                          AMERICAN CENTURY INVESTMENTS

                              INTERNATIONAL GROWTH

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        International  Growth seeks  capital  growth by  investing  primarily in
     foreign  equity  securities.  International  Growth  invests  primarily  in
     securities of issuers in developed countries.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund advisor looks for securities of international companies that it
     believes will  increase in value over time.  The fund advisor uses a growth
     investment  strategy developed by American Century that looks for companies
     whose  earnings  and  revenues  are not  only  growing,  but  growing  at a
     successively faster, or accelerating,  pace.  Accelerating growth is shown,
     for  example,  by growth that is faster this  quarter  than last and faster
     this year than the year before.

        Using American Century's  extensive computer database,  the fund advisor
     tracks  financial  information  for  thousands of companies to research and
     select the stocks it believes will be able to sustain  accelerating growth.
     This strategy is based on the premise that,  over the long term, the stocks
     of   companies   with   accelerating   earnings   and   revenues   have   a
     greater-than-average chance to increase in value. International Growth will
     have at least 65% of its  assets  invested  at all  times in  international
     equity securities.

        In addition to locating strong companies with accelerating earnings, the
     fund  advisor  believes  that the  diversification  of the fund's  holdings
     across different countries and geographical  regions is important in trying
     to manage the risks of an  international  portfolio.  For this reason,  the
     fund advisor also  considers  the prospects  for relative  economic  growth
     among  countries or regions,  economic and political  conditions,  expected
     inflation rates,  currency exchange  fluctuations,  and tax  considerations
     when making investments.

        Additional  information  about  International  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
     six-month 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  International  Growth's  shares  depends  on the value of the
     stocks and other securities it owns. The value of the individual securities
     International  Growth 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
     International  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,  nor is it  insured  or
     guaranteed  by the  Federal  Deposit  Insurance  Corporation  or any  other
     government agency.

    *International  Growth  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  International  Growth 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


INTERNATIONAL GROWTH                                AMERICAN CENTURY INVESTMENTS


     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,  International  Growth is intended  for  investors  who find
     foreign securities 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
     or to redeem  your  shares.  The  following  table  describes  the fees and
     expenses that you may pay if you buy and hold shares of the fund.

     ANNUAL FUND OPERATING EXPENSES
     (EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)
          Management Fee                               1.37%(1)
          Distribution and Service (12b-1) Fees        None

       (1)Based  upon assets at November  30,  1997.  The fund has a stepped fee
       schedule. As a result, the fund's management fee decreases as fund assets
       increase.

       independent  directors,  their legal counsel,  interest and extraordinary

5. WHO ARE THE FUND'S INVESTMENT ADVISOR AND PORTFOLIO MANAGERS?

        American  Century  Investment   Management,   Inc.  provides  investment
     advisory and management  services for the fund. American Century uses teams

     International Growth team are:

        HENRIK STRABO,  Senior Vice President and Portfolio Manager,  has been a
     member of the team that manages  International  Growth since April 1994. He
     joined American Century in 1993 as an Investment Analyst.

        MARK S.  KOPINSKI,  Vice  President  and Portfolio  Manager,  has been a
     member  of the team  that  manages  International  Growth  since  rejoining
     American  Century in April 1997.  Before  rejoining  American  Century,  he
     served as Vice President and Portfolio Manager of Federated Investors, Inc.
     from June 1995 to March 1997.  Prior to 1995,  he served as Vice  President
     and Portfolio Manager of American Century.

6. HOW DO I BUY FUND SHARES?

     * Complete and return the enclosed application

     * Call us and 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),  unless you establish an automatic
     investment  plan of at least $50 per  month.  If the value of your  account
     falls   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 the fund 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?

        International  Growth pays  distributions  of  substantially  all of its
     income  and  realized  capital  gains  once a year,  usually  in  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. Fund  shareholders also may be able to claim a foreign tax credit for
     any foreign  income taxes paid by the fund.  Distributions  are  reinvested
     automatically in additional shares unless you choose another option.

                          AMERICAN CENTURY INVESTMENTS

                             INTERNATIONAL DISCOVERY

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        International  Discovery seeks capital growth by investing  primarily in
     equity  securities of smaller foreign  companies.  These smaller  companies
     have a market  capitalization  (the number of shares times the share price)
     at the time of  investment  of less than $1  billion or will have less than
     $500 million in freely tradable securities.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund advisor looks for securities of international companies that it
     believes will  increase in value over time.  The fund advisor uses a growth
     investment  strategy developed by American Century that looks for companies
     whose  earnings  and  revenues  are not  only  growing,  but  growing  at a

     among  countries or regions,  economic and political  conditions,  expected
     inflation rates,  currency exchange  fluctuations,  and tax  considerations
     when making investments.

        Additional  information about International  Discovery'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
     six-month 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 International  Discovery's  shares depends on the value of the
     stocks and other securities it owns. The value of the individual securities
     International  Discovery  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
     International  Discovery 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,  nor is it  insured  or
     guaranteed  by the  Federal  Deposit  Insurance  Corporation  or any  other
     government agency.

    *International  Discovery  invests  primarily  in smaller  foreign  issuers.
     Investing in smaller foreign issuers is much riskier than investing in U.S.
     companies  or even  investing  in  foreign  securities  generally.  Smaller
     companies may have limited resources,  trade less frequently, and have less
     publicly available information.  Smaller companies in emerging markets also
     may be subject to government and economic instability,  the effect of which
     can  be  magnified  by the  country's  financial  markets.  Each  of  these
     potential factors may cause the fund's investments to be extremely volatile
     and could result in significant losses to the fund.

    *In addition to the risks of investing in smaller foreign  companies,  there
     are many risks associated with foreign investing generally. 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 International  Discovery 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.


INTERNATIONAL DISCOVERY                             AMERICAN CENTURY INVESTMENTS


     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,  International  Discovery is intended for investors who find
     foreign securities an appropriate  investment and who are willing to accept
     the increased risk of investing in smaller foreign companies. 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 or to reinvest  dividends  in  additional
     shares.


FUND PROFILE                                             INTERNATIONAL DISCOVERY


        THE FUND  CHARGES A  REDEMPTION  FEE OF 2.0% OF THE VALUE OF THE  SHARES
     SOLD WITHIN 180 DAYS OF THEIR PURCHASE.  This redemption fee is retained by
     the fund. It is intended to discourage short-term investment in the fund as
     well as to decrease the negative impact that  short-term  investors have on
     the  shareholders  remaining in the fund.  Otherwise,  there are no fees or
     charges  to  exchange  into the  Investor  Class  shares of other  American
     Century funds or to redeem your shares.  The following  table describes the
     fees and expenses that you may pay if you buy and hold shares of the fund.

     ANNUAL FUND OPERATING EXPENSES
     (EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)
          Management Fee                              1.68%(1)
          Distribution and Service (12b-1) Fees       None
          Other Expenses(2)                           0.00%
          Total Annual Fund Operating Expenses        1.68%(1)

       (1)Based  upon assets at November  30,  1997.  The fund has a stepped fee
       schedule. As a result, the fund's management fee decreases as fund assets
       increase.

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

          EXAMPLE OF HYPOTHETICAL FUND COSTS
             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 fund operating expenses shown above
                 . . . your cost of investing in the fund would be:

          1 year            3 years            5 years             10 years
          -----------------------------------------------------------------
           $170               $526               $907               $1,971

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

                             TWENTIETH CENTURY GROUP


                          AMERICAN CENTURY INVESTMENTS

                                EMERGING MARKETS

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        Emerging  Markets seeks capital growth by investing  primarily in equity
     securities of emerging market companies. The fund considers emerging market
     companies  to  be  companies  located  in  emerging  market  countries  and
     companies that derive a significant portion of their business from emerging
     market countries.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund advisor looks for securities of emerging market  companies that
     it believes  will  increase  in value over time.  The fund  advisor  uses a
     growth  investment  strategy  developed by American  Century that looks for
     companies whose earnings and revenues are not only growing,  but growing at
     a successively faster, or accelerating, pace. Accelerating growth is shown,
     for  example,  by growth that is faster this  quarter  than last and faster
     this year than the year before.

        Using American Century's  extensive computer database,  the fund advisor
     tracks  financial  information  for  thousands of companies to research and
     select the stocks it believes will be able to sustain  accelerating growth.
     This strategy is based on the premise that,  over the long term, the stocks
     of   companies   with   accelerating   earnings   and   revenues   have   a
     greater-than-average chance to increase in value.

        In addition to locating strong companies with accelerating earnings, the
     fund  advisor  believes  that the  diversification  of the fund's  holdings
     across different countries and geographical  regions is important in trying
     to manage the risks of an  international  portfolio.  For this reason,  the
     fund advisor also  considers  the prospects  for relative  economic  growth
     among  countries or regions,  economic and political  conditions,  expected
     inflation rates,  currency exchange  fluctuations,  and tax  considerations
     when making investments.

        Additional  information about Emerging Markets' 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
     six-month 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 Emerging  Markets'  shares  depends on the value of the stocks
     and  other  securities  it owns.  The  value of the  individual  securities
     Emerging  Markets 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 Emerging
     Markets 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,  nor is it  insured  or
     guaranteed  by the  Federal  Deposit  Insurance  Corporation  or any  other
     government agency.

    *Emerging Markets invests primarily in emerging market companies.  Investing
     in  emerging  market  companies  is much  riskier  than  investing  in U.S.
     companies  or even  investing  in foreign  securities  generally.  Emerging
     market countries may have extremely  unstable  governments and/or economies
     that are subject to sudden  change.  These  changes may be magnified by the
     country's  financial  markets  resulting in  significant  volatility in the
     fund's investments.  In addition to the risks of emerging market companies,
     there are many risks  associated with foreign  investing  generally.  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  Emerging  Markets  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


EMERGING MARKETS                                   AMERICAN CENTURY INVESTMENTS


     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,  Emerging Markets is intended for investors who find foreign
     securities  an  appropriate  investment  and who are  willing to accept the
     increased risk of investing in emerging market companies.  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
     or to redeem  your  shares.  The  following  table  describes  the fees and
     expenses that you may pay if you buy and hold shares of the fund.

      ANNUAL FUND OPERATING EXPENSES
     (EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)
          Management Fee                                2.00%(1)
          Distribution and Service (12b-1) Fees         None
          Other Expenses(2)                             0.00%
          Total Annual Fund Operating Expenses          2.00%(1)

       (1)Based  upon assets at November  30,  1997.  The fund has a stepped fee
       schedule. As a result, the fund's management fee decreases as fund assets
       increase.

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

           EXAMPLE OF HYPOTHETICAL FUND COSTS
              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 fund operating expenses shown above
                  . . . your cost of investing in the fund would be:

           1 year              3 years            5 years             10 years
           -------------------------------------------------------------------
            $202                 $623             $1,069               $2,305

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

        You will find more  information  about  these  choices  in our  Investor
     Services Guide, which you may request by calling us, accessing our Web site
     or visiting one of our Investor Centers.

        Information  contained  in  our  Investor  Services  Guide  pertains  to
     shareholders  who invest directly with American Century rather than through
     an employer-sponsored retirement plan or through a 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 an Institutional Service Representative at 1-800-345-3533.
