                            TWENTIETH CENTURY GROUP


                         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 managers look for  securities of  international  companies that
     they  believe  will  increase in value over time.  The fund  managers use a
     growth  investment  strategy  developed by American  Century that looks for
     companies with earnings and revenue growth. Ideally, the fund managers look
     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 or
     faster this year than the year before.

        The fund managers track financial information for thousands of companies
     to  research  and select the stocks  they  believe  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  managers  believe  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 managers also  consider 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 fiscal
     period. You may get these reports at no cost by calling us.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING INTERNATIONAL GROWTH 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  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
          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, and it is not insured
          or guaranteed by the Federal Deposit Insurance  Corporation  (FDIC) 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.


INTERNATIONAL GROWTH                                AMERICAN CENTURY INVESTMENTS


     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  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 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 will pay if you buy and hold shares of the fund.

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

     Total Annual Fund Operating Expenses        1.37%(1)

        (1)Based upon assets as of November 30, 1998. The fund has a stepped fee
        schedule. As a  result, the fund's management fee generally 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

              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
                 $139         $432        $746          $1,636

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

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
     of portfolio  managers,  assistant  portfolio managers and analysts working

     from the University of Washington.

        MARK S.  KOPINSKI,  Vice  President  and Portfolio  Manager,  has been a

     American  Century in April 1997.  Before  rejoining  American  Century,  he
     served as Vice President and Portfolio Manager at Federated Investors, Inc.
     from June 1995 to March 1997.  Prior to 1995,  he served as Vice  President
     and Portfolio  Manager of American  Century.  He has a bachelor's degree in
     business administration from the University of Illinois.

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  once a year,  usually  in  December.  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. 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 $1.5 billion or will have less than
     $500 million in freely tradable securities.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund managers look for  securities of  international  companies that
     they  believe  will  increase in value over time.  The fund  managers use a
     growth  investment  strategy  developed by American  Century that looks for

     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  managers  believe  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 managers also  consider 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  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 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 International  Discovery'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.

     *    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, and it is not insured
          or guaranteed by the Federal Deposit Insurance  Corporation  (FDIC) 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 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  tables describe the
     fees and expenses that you may pay if you buy and hold shares of the fund.

     ----------------------------------------------------------
      SHAREHOLDER FEES
     (FEES PAID DIRECTLY FROM YOUR INVESTMENT)
     ----------------------------------------------------------
      Redemption Fee
         Shares held less than 180 days              2.0%(1)
         Shares held for 180 days or more            None

        (1)This redemption fee is retained by 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, 1998. The fund has a stepped fee
        schedule. As a result, the fund's management fee generally 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

              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 managers look for securities of emerging market  companies that
     they  believe  will  increase in value over time.  The fund  managers use a
     growth  investment  strategy  developed by American  Century that looks for
     companies with earnings and revenue growth. Ideally, the fund managers look
     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 or
     faster this year than the year before.

        The fund managers track financial information for thousands of companies
     to  research  and select the stocks  they  believe  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  managers  believe  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 managers also  consider 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 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  Emerging  Markets'  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
          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, and it is not insured
          or guaranteed by the Federal Deposit Insurance  Corporation  (FDIC) 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  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.


Emerging Markets                                    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,  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 is not  appropriate for investors who are unable to tolerate rapid
     fluctuations in the value of their investment.

        expenses, 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 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.

     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.

                            TWENTIETH CENTURY GROUP


                         AMERICAN CENTURY INVESTMENTS
                                 GLOBAL GROWTH

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        Global  Growth seeks capital  growth by investing  primarily in U.S. and
     foreign equity securities of issuers in developed countries.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund  managers look for  securities  of both U.S. and  international
     companies  that they  believe  will  increase in value over time.  The fund
     managers use a growth  investment  strategy  developed by American  Century
     that looks for companies  with earnings and revenue  growth.  Ideally,  the
     fund managers look 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 or faster this year than the year before.

        The fund managers track financial information for thousands of companies
     to  research  and select the stocks  they  believe  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.

        Global Growth will have at least 65% of its assets invested at all times
     in equity securities of issuers in developed countries.  The fund considers
     developed countries to include the United States, Canada, Japan, the United
     Kingdom,  Germany,  Austria,  France, Italy,  Ireland,  Spain, Belgium, the
     Netherlands,  Switzerland,  Sweden, Finland, Norway, Denmark, Australia and
     New  Zealand.  The  fund  may also  invest  in  securities  of  issuers  in
     developing  countries  where the fund  managers  believe  they  present  an
     attractive investment opportunity for the fund.

        In addition to locating strong companies with accelerating earnings, the
     fund  managers  believe  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 managers also  consider 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.

3. WHAT ARE THE SIGNIFICANT RISKS OF INVESTING

 IN THE FUND?

     *    The value of Global 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.

     *    As with all  funds,  at any  given  time the  value of your  shares of
          Global  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.

     *    Global  Growth  may  invest a  significant  portion  of its  assets in
          foreign  securities,   which  generally  involve  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 Growth is determined in U.S.  dollars.  The fund's  foreign
     investments,  however,  generally  are held in the foreign  currency of the
     countries 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.


GLOBAL GROWTH                                       AMERICAN CENTURY INVESTMENTS


     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 losses 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.  Also, the information which is available could be
     less reliable than information regarding U.S. issuers.

        In summary,  Global  Growth is intended for  investors who find U.S. and
     foreign growth 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 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 will pay if you buy and hold shares of the fund.

     ----------------------------------------------------------
      ANNUAL FUND OPERATING EXPENSES
     (EXPENSES THAT ARE DEDUCTED FROM FUND ASSETS)
     ----------------------------------------------------------
           Management Fee                              1.30%(1)
           Distribution and Service (12b-1) Fees       None
           Other Expenses(2)                           0.00%
           Total Annual Fund Operating Expenses        1.30%(1)

        (1)The fund has a stepped fee schedule. As a result, the fund's
        management fee generally decreases as fund assets increase.

        (2)Other expenses include the fees and expenses of the fund's
        independent directors, their legal counsel, interest and extraordinary
        expenses.

           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 fund operating expenses shown above

               . . . your cost of investing in the fund would be:

                           1 year                  3 years
                            $132                    $410

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