EQUITY GROWTH FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

    Equity Growth seeks capital appreciation by investing in common stocks.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

    The fund's investment strategy utilizes  quantitative  management techniques
    in a two-step  process  that draws  heavily on computer  technology.  In the
    first step,  the fund  managers  rank stocks,  primarily  the 1,500  largest
    publicly  traded  companies in the United  States  (measured by the value of
    their stock),  from most attractive to least attractive.  This is determined
    by using a computer model that combines measures of a stock's value, as well
    as measures of its growth potential. To measure value, the fund managers use
    ratios of stock  price-to-book  value and stock  price-to-cash  flow,  among
    others. To measure growth,  the fund managers use, among others, the rate of
    growth of a company's  earnings and changes in the earnings  estimates for a
    company.

    In the second  step,  the fund  managers  use a technique  called  portfolio
    optimization.  In portfolio  optimization,  the fund managers use a computer
    model to build a portfolio  of stocks  that they  believe  will  provide the
    optimal  balance  between  risk and  expected  return of the  portfolio,  as
    measured in the stock  ranking  completed in the first step.  The goal is to
    create a fund that provides  better  returns than the S&P 500 without taking
    on significant additional risk.

    The fund may invest in  securities  other than stocks,  such as  convertible
    securities,  foreign  securities,  short-term  instruments and non-leveraged
    stock index futures contracts.  "Non-leveraged"  means that the fund may not
    invest in futures contracts where it would be possible to lose more than the
    fund invested.

    Additional information about Equity Growth's investments is available in its
    annual and semiannual  reports.  In these reports you will find a discussion
    of the  market  conditions  and  investment  strategies  that  significantly
    affected the fund's  performance  during the most recent fiscal period.  You
    may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

    * The value of Equity Growth's shares depends on the value of the stocks and
    other  securities it owns. The value of the individual  securities  that the
    fund owns will go up and down depending on the  performance of the companies
    that issued  them,  general  market and  economic  conditions,  and investor
    confidence.

    * Market  performance  tends to be  cyclical  and,  in the  various  cycles,
    certain investment styles may fall in and out of favor. If the market is not
    favoring  the fund's  style,  the fund's  gains may not be as big as, or its
    losses may be bigger than,  other equity  funds using  different  investment
    styles.

    * As with all funds,  at any given  time the value of your  shares of Equity
    Growth may be worth  more or less than the price you paid.  If you sell your
    shares when the value is less than the price you paid, you will lose money.

    * An investment in the fund is not a bank deposit,  and it is not insured or
    guaranteed by the Federal Deposit Insurance  Corporation (FDIC) or any other
    government agency.

    * Although  the fund  managers  invest the fund's  assets  primarily in U.S.
    stocks, Equity Growth can invest in securities of foreign companies. Foreign
    securities can have certain unique risks, including fluctuations in currency
    exchange  rates,  less stable  political  and economic  structures,  reduced
    availability  of  public  information,  and the  lack of  uniform  financial
    reporting and regulatory practices similar to those that apply in the United
    States. These factors make investing in foreign securities generally riskier
    than investing in U.S. stocks.

    In  summary,  Equity  Growth is  intended  for  investors  who seek  capital
    appreciation  through an equity fund and who are willing to accept the risks
    associated with the fund's investment strategy.

4. WHAT ARE THE FUND'S FEES AND EXPENSES?

    There are no sales loads, fees or other charges

    * to buy fund shares directly from American Century

    * to reinvest dividends in additional shares

    * to exchange into the Investor Class shares of other American Century fund

    * to redeem your shares

    The following table describes the fees and expenses that you will pay if you
    buy and hold shares of the fund.

     ANNUAL FUND OPERATING EXPENSES
     (EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)
     ---------------------------------------------
          Management Fee                                        0.69%(1)
          Distribution and Service (12b-1) Fees                 None
          Other Expenses(2)                                     0.00%
          Total Annual Fund Operating Expenses                  0.69%

        (1) Based on expenses  incurred  during the fund's  most  recent  fiscal
        year.  The fund has a stepped  fee  schedule.  As a result,  the  fund's
        management fee rate generally decreases as fund assets increase.

        (2) Other  expenses,  which  include the fees and expenses of the fund's
        independent directors, their legal counsel and interest, are expected to
        be less than 0.005% for the current fiscal year.

           EXAMPLE
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem all of your shares at the end of the periods shown below
             * earn a 5% return each year
             * incur the same operating expenses as shown above
             . . . your cost of investing in the fund would be:

                   1 year        3 years        5 years        10 years
                   $70           $220           $383           $856

            Of course,  actual costs may be higher or lower. Use this example to
            compare the costs of investing in other funds.

    American Century offers several ways to purchase shares

    * Complete  and return the  enclosed  application  along with an  investment
    check payable to American Century Investments

    * If you already have an American Century account, call us or access our Web
    site to exchange shares from another American Century fund

    * Call us and send your investment by bank wire transfer

    Your  initial  investment  must be at least $2,500  ($1,000 for  traditional
    IRAs, Roth IRAs and UGMA/UTMA accounts).  If your redemption activity causes
    the value of your  account to fall below this account  minimum,  your shares
    may be redeemed involuntarily.

7. HOW DO I SELL FUND SHARES?

    You may sell all or part of your fund shares on any  business day by writing
    or calling us. You also may exchange your shares in Equity Growth for shares
    in nearly 70 other mutual funds  offered by American  Century.  Depending on
    the options you select when you open your  account,  some  restrictions  may
    apply.  For your  protection,  some redemption  requests require a signature
    guarantee.

8. HOW ARE FUND DISTRIBUTIONS MADE AND TAXED?

    Equity  Growth  pays  distributions  of  substantially  all  of  its  income
    quarterly.  Distributions from realized capital gains are paid twice a year,
    usually in March and  December.  Distributions  may be  taxable as  ordinary
    income,  capital gains or a combination of the two.  Capital gains are taxed
    at  different  rates  depending  on the  length  of time the  fund  held the
    securities that were sold.  Distributions  are reinvested  automatically  in
    additional shares unless you choose another option.

    employer-sponsored retirement plan or financial intermediary.

    If  you  own  or  are   considering   purchasing   fund  shares  through  an
    employer-sponsored  retirement plan or financial intermediary,  your ability
    to purchase  shares of the fund,  exchange them for shares of other American
    Century  funds,  and  redeem  them will  depend on the terms of your plan or
    financial  intermediary.  If  you  have  questions  about  investing  in  an
    employer-sponsored retirement plan or through a financial intermediary, call

INCOME & GROWTH FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

    Income  &  Growth  seeks  dividend   growth,   current  income  and  capital
    appreciation by investing in common stocks.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

    The fund's investment strategy utilizes  quantitative  management techniques
    in a two-step  process  that draws  heavily on computer  technology.  In the
    first step,  the fund  managers  rank stocks,  primarily  the 1,500  largest
    publicly  traded  companies in the United  States  (measured by the value of
    their stock),  from most attractive to least attractive.  This is determined
    by using a computer model that combines  measures of a stock's value as well
    as measures of its growth potential. To measure value, the fund managers use
    ratios of stock  price-to-book  value and stock  price-to-cash  flow,  among
    others. To measure growth,  the fund managers use, among others, the rate of
    growth of a company's  earnings and changes in the earnings  estimates for a
    company.

    In the second  step,  the fund  managers  use a technique  called  portfolio
    optimization.  With portfolio optimization, the fund managers use a computer
    model to build a portfolio  of stocks  that they  believe  will  provide the
    optimal  balance  between  risk and  expected  return  of the  portfolio  as
    measured in the stock  ranking  completed in the first step.  The goal is to
    create a fund that provides  better  returns than the S&P 500 without taking
    on significant additional risk. When building the fund's portfolio, the fund
    managers  also attempt to create a dividend  yield for the fund that will be
    greater than that of the S&P 500.

    The fund may invest in  securities  other than stocks,  such as  convertible
    securities,  foreign  securities,  short-term  instruments and non-leveraged
    stock index futures contracts.  "Non-leveraged"  means that the fund may not
    invest in futures contracts where it would be possible to lose more than the
    fund invested.

    Additional  information about Income & Growth's  investments is available in
    its  annual  and  semiannual  reports.  In these  reports  you  will  find a
    discussion  of  the  market   conditions  and  investment   strategies  that
    significantly  affected the fund's performance during the most recent fiscal
    period. You may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

    * The value of Income & Growth's  shares  depends on the value of the stocks
    and other  securities it owns. The value of the individual  securities  that
    the  fund  owns  will go up and down  depending  on the  performance  of the
    companies  that issued them,  general  market and economic  conditions,  and
    investor confidence.

    * Market  performance  tends to be  cyclical  and,  in the  various  cycles,
    certain investment styles may fall in and out of favor. If the market is not
    favoring  the fund's  style,  the fund's  gains may not be as big as, or its
    losses may be bigger than,  other equity  funds using  different  investment
    styles.

    * As with all funds,  at any given time the value of your shares of Income &
    Growth may be worth  more or less than the price you paid.  If you sell your
    shares when the value is less than the price you paid, you will lose money.

    * An investment in the fund is not a bank deposit,  and it is not insured or
    guaranteed by the Federal Deposit Insurance  Corporation (FDIC) or any other
    government agency.

    * Although  the fund  managers  invest the fund's  assets  primarily in U.S.
    stocks,  Income & Growth can  invest in  securities  of  foreign  companies.
    Foreign securities can have certain unique risks,  including fluctuations in
    currency  exchange  rates,  less stable  political and economic  structures,
    reduced  availability  of  public  information,  and  the  lack  of  uniform
    financial reporting and regulatory  practices similar to those that apply in
    the United  States.  These  factors  make  investing  in foreign  securities
    generally riskier than investing in U.S. stocks.

    In summary,  Income & Growth is intended  for  investors  who seek  dividend
    growth,  current income and capital  appreciation through an equity fund and
    who are willing to accept the risks  associated  with the fund's  investment
    strategy.

        (1) Based on expenses  incurred  during the fund's  most  recent  fiscal
        year.  The fund has a stepped  fee  schedule.  As a result,  the  fund's
        management fee rate generally decreases as fund assets increase.

        (2) Other  expenses,  which  include the fees and expenses of the fund's
        independent directors, their legal counsel and interest, are expected to
        be less than 0.005% for the current fiscal year.

           EXAMPLE
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem all of your shares at the end of the periods shown below
             * earn a 5% return each year
             * incur the same operating expenses as shown above
             . . . your cost of investing in the fund would be:

                   1 year       3 years       5 years       10 years
                   $70          $220          $383          $856

             Of course, actual costs may be higher or lower. Use this example to
             compare the costs of investing in other funds.

GLOBAL GOLD FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

    Global Gold seeks to realize a total return  (capital  growth and dividends)
    consistent  with  investment in securities of companies  that are engaged in
    mining,  processing,  fabricating  or  distributing  gold or other  precious
    metals throughout the world.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

    The fund's investment strategy utilizes  quantitative  management techniques
    as well as fundamental stock selection in a two-part process. The first part
    involves  selecting  stocks  based on several  valuation  criteria,  without
    comparing the fund's holdings to the holdings of an index or benchmark.

    In the second part of the  process,  the  managers  use a  technique  called
    portfolio  optimization.  In  portfolio  optimization,  the  managers  use a
    computer model to build a portfolio of stocks that they believe will provide
    the optimal balance between risk relative to the fund's benchmark,  which is
    described  below,  and expected return of the fund, as measured in the stock
    ranking  completed  in the  first  step.  The goal is to  create a fund that
    produces  performance  similar to performance of the worldwide gold equities
    market.

    The managers use a  proprietary  benchmark  that the advisor  developed  and
    monitors  that   represents  the  worldwide  gold  equities   market.   This
    proprietary  benchmark  contains  securities of companies engaged in mining,
    processing,  exploring for or otherwise  dealing with gold or other precious
    metals (Gold  Companies).  To be included in the  benchmark,  Gold Companies
    must be a certain size and receive a minimum  percentage  of their  revenues
    from  gold-related  activities or have a minimum  percentage of their assets
    invested in gold-related assets.

    Global  Gold  will   concentrate  its  investments  in  securities  of  Gold
    Companies. Under normal circumstances, at least 65% of the value of the fund
    will be invested in such  companies.  When the  managers  believe that it is
    prudent,  the fund may  invest in  securities  other  than  stocks,  such as
    convertible   securities,   sponsored  or  unsponsored  American  Depositary
    Receipts,  gold,  gold  certificates  or gold  futures.  Normally,  the fund
    managers will invest in securities of companies in at least three  different
    countries.

    The fund may invest in  securities  other than stocks,  such as  convertible
    securities, foreign securities other than stocks, short-term instruments and
    non-leveraged stock index futures contracts.  "Non-leveraged" means that the
    fund may not invest in futures  contracts where it would be possible to lose
    more than the fund invested.  Global Gold also may purchase debt securities,
    such as notes, bonds, debentures or commercial paper.

    Additional  information about Global Gold's  investments is available in its
    annual and semiannual  reports.  In these reports you will find a discussion
    of the  market  conditions  and  investment  strategies  that  significantly
    affected the fund's  performance  during the most recent fiscal period.  You
    may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

    * The value of Global Gold's  shares  depends on the value of the stocks and
    other securities it owns. The value of the individual securities Global Gold
    owns will go up and down depending on the  performance of the companies that
    issued  them,   general  market  and  economic   conditions,   and  investor
    confidence.

    * As with all funds,  at any given  time the value of your  shares of Global
    Gold may be worth  more or less than the  price  you paid.  If you sell your
    shares when the value is less than the price you paid, you will lose money.

    * An investment in the fund is not a bank deposit,  and it is not insured or
    guaranteed by the Federal Deposit Insurance  Corporation (FDIC) or any other
    government agency.

    * Because Global Gold concentrates its investments in Gold Companies, it may
    be  subject  to  greater  risks and  market  fluctuations  than a  portfolio
    representing  a broader  range of  industries.  Gold  stocks  generally  are
    considered speculative because of their high share price volatility, and the
    fund's share price may be affected by this volatility.

    * Many  investors  believe that gold  investments  hedge against  inflation,
    currency  devaluations,  and general stock market declines,  but there is no
    guarantee that these historical inverse relationships will continue.


Global Gold                                    American Century Investments


    * Global Gold  invests  primarily  in foreign  securities,  which  generally
    involves  greater risks than investing in U.S.  securities.  These risks are
    summarized below:

        Currency  Risk.  In  addition  to  changes  in the  value of the  fund's
        investments, changes in the value of foreign currencies against the U.S.
        dollar also could result in gains or losses to the fund.  The value of a
        share  of  Global  Gold  is  determined  in  U.S.  dollars.  The  fund's
        investments,  however, generally are held in the foreign currency of the
        country  where  investments  are  made.  As a  result,  the  fund  could
        recognize a gain or loss based solely upon a change in the exchange rate
        between the foreign currency and the U.S. dollar.

        Political and Economic Risk.  Many countries  where the fund invests are
        not as politically or economically  developed as the United States. As a
        result,  the  economies  and  political  and social  structures of these
        countries  could be unstable and exert forces that could cause the value
        of the fund's investments to decrease.  The fund also could be unable to
        enforce its ownership rights or pursue legal remedies in countries where
        it invests.

        Market and Trading Risk. The trading markets for many foreign securities
        are  not as  active  as U.S.  markets  and may  have  less  governmental
        regulation  and oversight.  Foreign  markets also may have clearance and
        settlement  procedures  that make it  difficult  for the fund to buy and
        sell  securities.  These  factors  could result in a loss to the fund by
        causing  the fund to be unable to dispose of an  investment,  by causing
        the fund to miss an  attractive  investment  opportunity,  or by causing
        fund assets to be uninvested for some period of time.

        Availability of Information. Foreign companies generally are not subject
        to  the  regulatory  controls  or  uniform  accounting,   auditing,  and
        financial  reporting  standards  imposed on U.S.  issuers.  As a result,
        there may be less publicly  available  information about foreign issuers
        than is available regarding U.S. issuers.

    In summary, Global Gold is intended for investors who find Gold Companies an
    appropriate  investment  and who are  willing to accept the  increased  risk
    associated with the fund's  investment  strategy.  An investment in the fund
    should  not  be  considered  a  complete   investment  program  and  is  not
    appropriate  for investors who are unable to tolerate rapid  fluctuations in
    the value of their investment.

                                                                        address.


GLOBAL NATURAL RESOURCES FUND


1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

    Global Natural Resources seeks to realize a total return (capital growth and
    dividends)  consistent  with  investment in securities of companies that are
    engaged in the natural resources industries.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

    Global Natural  Resources will  concentrate its investments in securities of
    companies engaged in the natural resources industries. The fund's investment
    strategy  utilizes  some  quantitative  management  techniques  as  well  as
    fundamental  stock  selection.  The fund managers build the fund's portfolio
    using a top-down approach. They first consider factors in the global economy
    that affect the supply and demand in commodity  markets.  The managers  then
    review  those  factors  and  how  they  affect  particular  industries,  and
    determine whether to over- or under-weight  certain  industries  compared to
    the  benchmark.  The managers next consider the cost structure of individual
    companies  and analyze the  economies of the regions where the companies are
    located or operate.  The managers then create a selection list of stocks for
    the portfolio.

    The selection list is then compared to the fund's  benchmark using portfolio
    optimization.  In portfolio optimization,  the managers use a computer model
    to build a portfolio  of stocks from the  selection  list that they  believe
    will provide the optimal balance between risk and expected return.  The goal
    is to create a fund that provides better returns than the benchmark  without
    taking on significant  additional  risk. The fund's benchmark is a subset of
    companies in the energy and basic  materials  sectors of the Dow Jones World
    Stock Index* (DJWSI).

    The managers do not attempt to time the market. Instead, they intend to keep
    Global Natural Resources  essentially fully invested in stocks regardless of
    the movement of stock prices  generally.  The managers also may invest up to
    35% of the fund's assets in when-issued and forward commitment agreements if
    necessary to purchase securities.  In these agreements the transaction price
    and yield are each fixed at the time the  commitment  is made,  but  payment
    typically occurs 15 to 45 days later.

    The fund may invest in  securities  other than stocks,  such as  convertible
    securities, foreign securities other than stocks, short-term instruments and
    non-leveraged stock index futures contracts.  "Non-leveraged" means that the
    fund may not invest in futures  contracts where it would be possible to lose
    more than the fund invested.

    Additional  information  about  Global  Natural  Resources'  investments  is
    available in its annual and  semiannual  reports.  In these reports you will
    find a discussion of the market  conditions and investment  strategies  that
    significantly  affected the fund's performance during the most recent fiscal
    period. You may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

    * The value of Global Natural  Resources' shares depends on the value of the
    stocks and other securities it owns. The value of the individual  securities
    Global  Natural  Resources  owns  will  go up  and  down  depending  on  the
    performance of the companies  that issued them,  general market and economic
    conditions, and investor confidence.

    * As with all funds,  at any given  time the value of your  shares of Global
    Natural  Resources may be worth more or less than the price you paid. If you
    sell your  shares  when the value is less than the price you paid,  you will
    lose money.

    * An investment in the fund is not a bank deposit,  and it is not insured or
    guaranteed by the Federal Deposit Insurance  Corporation (FDIC) or any other
    government agency.

    * Because Global Natural  Resources  concentrates its investments in natural
    resource  companies,   it  may  be  subject  to  greater  risks  and  market
    fluctuations  than a portfolio  representing  a broader range of industries.
    Historically,  the  securities  of some natural  resources  companies may be
    subject to broad price fluctuations  during periods of economic or financial
    instability.  These  fluctuations  may cause  volatility in the fund's share
    price.

    * The DJWSI is the property of Dow Jones & Co., Inc.


Global Natural Resources                       American Century Investments


    * Many investors  believe that  investments in natural  resources  companies
    hedge against  commodity-price-driven  inflation,  but there is no guarantee
    that this historical inverse relationship will continue.

    * Depending on the composition of the sectors,  Global Natural Resources may
    invest in foreign  securities,  which generally  involves greater risks than
    investing in U.S. securities. These risks are summarized below:

        Currency  Risk.  In  addition  to  changes  in the  value of the  fund's
        investments, changes in the value of foreign currencies against the U.S.
        dollar also could result in gains or losses to the fund.  The value of a
        share of Global  Natural  Resources is determined in U.S.  dollars.  The
        fund's investments,  however, generally are held in the foreign currency
        of the country where  investments are made. As a result,  the fund could
        recognize a gain or loss based solely upon a change in the exchange rate
        between the foreign currency and the U.S. dollar.

        Political and Economic Risk.  Many countries  where the fund invests are
        not as politically or economically  developed as the United States. As a
        result,  the  economies  and  political  and social  structures of these
        countries  could be unstable and exert forces that could cause the value
        of the fund's investments to decrease.  The fund also could be unable to
        enforce its ownership rights or pursue legal remedies in countries where
        it invests.

        Market and Trading Risk. The trading markets for many foreign securities
        are  not as  active  as U.S.  markets  and may  have  less  governmental
        regulation  and oversight.  Foreign  markets also may have clearance and
        settlement  procedures  that make it  difficult  for the fund to buy and
        sell  securities.  These  factors  could result in a loss to the fund by
        causing  the fund to be unable to dispose of an  investment,  by causing
        the fund to miss an  attractive  investment  opportunity,  or by causing
        fund assets to be uninvested for some period of time.

        Availability of Information. Foreign companies generally are not subject
        to  the  regulatory  controls  or  uniform  accounting,   auditing,  and
        financial  reporting  standards  imposed on U.S.  issuers.  As a result,
        there may be less publicly  available  information about foreign issuers
        than is available regarding U.S. issuers.

    In summary,  Global  Natural  Resources is intended for  investors  who find
    natural resources companies an appropriate investment and who are willing to
    accept the increased risk associated with the fund's investment strategy. An
    investment  in the fund  should  not be  considered  a  complete  investment
    program  and is not  appropriate  for  investors  who are unable to tolerate
    rapid fluctuations in the value of their investment.

4. WHAT ARE THE FUND'S FEES AND EXPENSES?

    There are no sales loads, fees or other charges

    *  to buy fund shares directly from American Century

    *  to reinvest dividends in additional shares

    *  to exchange into the Investor Class shares of other American Century
       funds

    *  to redeem your shares.

    The following table describes the fees and expenses that you will pay if you
    buy and hold shares of the fund.

     ANNUAL FUND OPERATING EXPENSES
     (EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)
     ---------------------------------------------
         Management Fee                               0.69%(1)
         Distribution and Service (12b-1) Fees        None
         Other Expenses(2)                            0.00%
         Total Annual Fund Operating Expenses         0.69%

        (1) Based on expenses  incurred  during the fund's  most  recent  fiscal
        year.  The fund has a stepped  fee  schedule.  As a result,  the  fund's
        management fee rate generally decreases as fund assets increase.

        (2) Other  expenses,  which  include the fees and expenses of the fund's
        independent directors,  their legal counsel and interest, were less than
        0.005% for the most recent fiscal year.

           EXAMPLE
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem your shares at the end of the periods shown below
             * earn a 5% return each year
             * incur the same operating expenses shown above
             . . . your cost of investing in the fund would be:

                      1 year         3 years         5 years          10 years
                       $70            $220             $383              $856

             Of course, actual costs may be higher or lower. Use this example to
             compare the costs of investing in other funds.

UTILITIES FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

    Utilities  seeks current income and long-term  growth of capital and income.
    The fund invests  primarily in equity securities of companies engaged in the
    utilities industry.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

    Utilities invests primarily in equity securities of companies engaged in the
    utilities  industry.  The fund's investment  strategy utilizes  quantitative
    management   techniques  in  a  two-part  process  that  utilizes   computer
    technology.  The first part  involves  ranking  stocks on the basis of their
    growth and valuation characteristics. Examples of growth characteristics are
    earnings growth rates and changes in analyst earnings estimates. Examples of
    valuation characteristics are price-to-earnings and price-to-book ratios.

    In the second part of the process,  the fund managers use a technique called
    portfolio optimization.  In portfolio optimization,  the fund managers use a
    computer model to build a portfolio of stocks that they believe will provide
    the optimal balance between risk relative to the fund's benchmark,  which is
    described  below,  and expected return of the fund, as measured in the stock
    ranking completed in the first step.

    Under normal market conditions,  Utilities invests at least 75% of its total
    assets in stocks of companies  engaged in the  utilities  industry.  Of this
    75%, the fund managers  will not buy shares of a company  unless 50% or more
    of the  company's  revenues  or net  profits  come  from  the  ownership  or
    operation  of  facilities   used  to  provide   electricity,   natural  gas,
    telecommunications  services, cable television,  water or sanitary services.
    Utilities  may  invest  up to  25%  of  its  total  assets  in  fixed-income
    securities.

    The fund may invest in  securities  other than stocks,  such as  convertible
    securities,  foreign  securities,  short-term  instruments and non-leveraged
    stock index futures contracts.  "Non-leveraged"  means that the fund may not
    invest in futures contracts where it would be possible to lose more than the
    fund invested.

    The fund's benchmark is a market  capitalization-weighted index of companies
    engaged in the  utilities  industry  as defined  above and whose  shares are
    traded in the United States. It is an internally  developed index maintained
    by the fund advisor.  The index is changed periodically to reflect corporate
    actions such as mergers and acquisitions.  It also may be changed to reflect
    underlying trends in the utilities  industry over time. Changes in the index
    may induce changes to the fund's  holdings.  As of the end of December 1998,
    the  benchmark  was  comprised of 163  companies  with an  aggregate  market
    capitalization of almost $1.02 trillion.  The average market  capitalization
    of the companies in the benchmark was $6.26 billion.

    Additional  information  about  Utilities'  investments  is available in its
    annual and semiannual  reports.  In these reports you will find a discussion
    of the  market  conditions  and  investment  strategies  that  significantly
    affected the fund's  performance  during the most recent fiscal period.  You
    may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

    * The value of  Utilities'  shares  depends  on the value of the  stocks and
    other  securities it owns. The value of the individual  securities  that the
    fund owns will go up and down depending on the  performance of the companies
    that issued  them,  general  market and  economic  conditions,  and investor
    confidence.

    * As with all funds, at any given time the value of your shares of Utilities
    may be worth more or less than the price you paid.  If you sell your  shares
    when the value is less than the price you paid, you will lose money.

    * An investment in the fund is not a bank deposit,  and it is not insured or
    guaranteed by the Federal Deposit Insurance  Corporation (FDIC) or any other
    government agency.


Utilities                                     American Century Investments


    * Because Utilities concentrates its investments in utilities companies,  it
    may be subject to greater  risks and market  fluctuations  than a  portfolio
    representing  a broader range of  industries.  As an example of these risks,
    companies in the  telecommunications  and electric utilities industries have
    experienced  substantial changes in the amount and type of regulation at the
    state and federal levels.  While creating  opportunities for some companies,
    it also has  increased  the  uncertainty  for others with  respect to future
    revenues and  earnings.  This trend may continue for some time and increased
    share price volatility may result.

    * Although  the fund  managers  invest the fund's  assets  primarily in U.S.
    stocks,  Utilities can invest in securities  of foreign  companies.  Foreign
    securities can have certain unique risks, including fluctuations in currency
    exchange  rates,  less stable  political  and economic  structures,  reduced
    availability of public information,  and lack of uniform financial reporting
    and regulatory  practices  similar to those that apply in the United States.
    These factors make investing in foreign  securities  generally  riskier than
    investing in U.S. stocks.

    long-term  capital  growth  and  income  through  investments  in  utilities
    companies,  and who are  willing  to accept  the risks  associated  with the

SMALL CAP QUANTITATIVE FUND

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

    Small Cap Quantitative seeks capital  appreciation by investing primarily in
    common stocks of small companies.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

    The fund's investment strategy utilizes  quantitative  management techniques
    in a two-step  process  that draws  heavily on computer  technology.  In the
    first step,  the fund managers rank stocks,  primarily of smaller  companies
    (measured  by the  value of their  stock),  from  most  attractive  to least
    attractive.  This is  determined  by using a computer  model  that  combines
    measures of a stock's value, as well as measures of its growth potential. To
    measure value, the fund managers use ratios of stock price-to-book value and
    stock price-to-cash flow, among others. To measure growth, the fund managers
    use, among others, the rate of growth of a company's earnings and changes in
    the earnings estimates for a company.

    In the second  step,  the fund  managers  use a technique  called  portfolio
    optimization.  In portfolio  optimization,  the fund managers use a computer
    model to build a portfolio  of stocks  that they  believe  will  provide the
    optimal  balance  between  risk and  expected  return of the  portfolio,  as
    measured in the stock  ranking  completed in the first step.  The goal is to
    create a fund that provides  better returns than the S&P Small-Cap 600 Index
    without taking on significant additional risk.

    The fund invests  primarily in common stocks of companies which, at the time
    of  investment,  have market  capitalization  not  greater  than that of the
    largest company in the S&P Small-Cap 600 Index.  The S&P Small-Cap 600 Index
    is an unmanaged stock index that tracks the performance of equity securities
    of smaller companies.  As of June 30, 1999, the largest company in the index
    had a market capitalization of approximately $2.6 billion,  while the median
    company  in the  index had a market  capitalization  of  approximately  $483
    million.

    The fund may invest in  securities  other than stocks,  such as  convertible
    securities,  foreign  securities,  short-term  instruments and non-leveraged
    stock index futures contracts.  "Non-leveraged"  means that the fund may not
    invest in futures contracts where it would be possible to lose more than the
    fund invested.

    Additional  information  about  Small  Cap  Quantitative's   investments  is
    available  in  its  semiannual  report.  In  this  report  you  will  find a
    discussion  of  the  market   conditions  and  investment   strategies  that
    significantly  affected the fund's performance during the most recent fiscal
    period. You may get this report at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING IN THE FUND?

    * The value of Small Cap  Quantitative's  shares depends on the value of the
    stocks and other securities it owns. The value of the individual  securities
    the  fund  owns  will go up and down  depending  on the  performance  of the
    companies  that issued them,  general  market and economic  conditions,  and
    investor confidence.

    * Market  performance  tends to be  cyclical  and,  in the  various  cycles,
    certain investment styles may fall in and out of favor. If the market is not
    favoring  the fund's  style,  the fund's  gains may not be as big as, or its
    losses may be bigger than,  other equity  funds using  different  investment
    styles.

    * As with all funds, at any given time the value of your shares of Small Cap
    Quantitative  may be worth more or less than the price you paid. If you sell
    your  shares  when the value is less than the price you paid,  you will lose
    money.

    * An investment in the fund is not a bank deposit,  and it is not insured or
    guaranteed by the Federal Deposit Insurance  Corporation (FDIC) or any other
    government agency.

    * Although  the fund  managers  invest the fund's  assets  primarily in U.S.
    stocks,   Small  Cap  Quantitative  can  invest  in  securities  of  foreign
    companies.  Foreign  securities  can have certain  unique  risks,  including
    fluctuations in currency  exchange rates, less stable political and economic
    structures,  reduced  availability  of public  information,  and the lack of
    uniform financial  reporting and regulatory  practices similar to those that
    apply  in the  United  States.  These  factors  make  investing  in  foreign
    securities generally riskier than investing in U.S. stocks.


Small Cap Quantitative                        American Century Investments


    In summary,  Small Cap  Quantitative  is  intended  for  investors  who seek
    capital appreciation through a small capitalization  equity fund and who are
    willing to accept the risks associated with the fund's investment strategy.

4. WHAT ARE THE FUND'S FEES AND EXPENSES?

    There are no sales loads, fees or other charges

    * to buy fund shares directly from American Century

    * to reinvest dividends in additional shares

    * to exchange into the Investor Class shares of other American Century fund

    * to redeem your shares

    The following table describes the fees and expenses that you will pay if you
    buy and hold shares of the fund.

     ANNUAL FUND OPERATING EXPENSES

     ---------------------------------------------

        (1) Based on expenses  incurred  during the fund's  most  recent  fiscal
        year.  The fund has a stepped  fee  schedule.  As a result,  the  fund's
        management fee rate generally decreases as fund assets increase.

        (2) Other  expenses,  which  include the fees and expenses of the fund's
        independent directors, their legal counsel and interest, are expected to
        be less than 0.005% for the current fiscal year.

           EXAMPLE
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem all of your shares at the end of the periods shown below
             * earn a 5% return each year
             * incur the same operating expenses as shown above

                   $96                              $299
