[front cover]

                              INTERNATIONAL GROWTH

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        International  Growth seeks  capital  growth by  investing  primarily in
     international 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 managers use 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.  Our  growth  strategy  is an  aggressive
     strategy that pursues superior long-term returns for fund shareholders.

        Using American Century's extensive computer database, the 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 risk of an  international  portfolio.  For this  reason,  the
     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
     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  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.  Additionally,  an  investment  in the fund is not a bank
     deposit,  nor is it insured 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.  The
     potential risks of foreign  investing are explained in detail in the fund's
     prospectus, a summary of which is set forth 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  could  also  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,  are generally 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 could exert forces which could cause
          the value of the fund's  investments to decrease.  The fund could also
          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
          government regulation and oversight.


INTERNATIONAL GROWTH                              AMERICAN CENTURY INVESTMENTS


          Foreign markets may also 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.

              * 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

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

     together  to  manage  our  mutual  funds.  The  portfolio  managers  on the
     International Growth team are:

        HENRIK  STRABO,  Senior Vice  President  and Portfolio  Manager,  joined
     American Century in 1993 as an Investment Analyst. In 1995, he was promoted
     to Portfolio Manager.  Prior to joining American Century, Mr. Strabo served
     as Vice President, International Equity Sales with Barclays de Zoete Wedd.

        MARK  S.  KOPINSKI,  Vice  President  and  Portfolio  Manager,  rejoined
     American  Century  in  1997  following  two  years  as Vice  President  and
     Portfolio Manager of Federated Investors,  Inc. Prior to 1995, Mr. Kopinski
     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 $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 the 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 may also  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 that the fund held the securities that were
     sold. Fund  shareholders may also 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.

9. WHAT SERVICES ARE AVAILABLE?

        American Century offers several ways to make it easier for you to manage
     your account, such as:

     *    telephone transactions

     *    wire and electronic funds transfers

     our Web site, or by 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 Services Representative at 1-800-345-3533.

[front cover]

                             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  tradeable  securities.  As much as one-half of the
     fund may be invested in emerging market 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 managers use 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.  Our  growth  strategy  is an  aggressive
     strategy that pursues superior long-term returns for fund shareholders.

        Using American Century's extensive computer database, the 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 Discovery
     will  have at least 65% of its  assets  invested  at all  times in  smaller
     foreign companies.

        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 risk of an  international  portfolio.  For this  reason,  the
     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
     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  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.  Additionally,  an  investment  in the fund is not a bank
     deposit,  nor is it insured by the Federal  Deposit  Insurance  Corporation
     (FDIC) or any other government agency.

  *  International  Discovery  invests  primarily in smaller foreign issuers and
     may invest up to 50% of its assets in emerging market countries.  Investing
     in smaller foreign issuers,  especially those in emerging market countries,
     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 may also 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
     investment 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 are
     explained  in detail in the  fund's  prospectus,  a summary of which is set
     forth 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  could  also  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,  are generally held in the
          foreign


INTERNATIONAL DISCOVERY                             AMERICAN CENTURY INVESTMENTS


          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 could exert forces which could cause
          the value of the fund's  investments to decrease.  The fund could also
          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
          government  regulation  and oversight.  Foreign  markets may also 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.

           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 operating expenses shown above

                  your cost of investing in the fund would be:

           -------------------------------------------------------------------
                 1 year          3 years         5 years       10 years
           -------------------------------------------------------------------
                  $170             $530            $910         $1,970

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

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 $10,000.  If the value of your account
     falls below the 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 may also exchange  your shares in  International
     Discovery  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.

        IF YOU SELL SHARES OF  INTERNATIONAL  DISCOVERY WITHIN 180 DAYS OF THEIR
     PURCHASE,  YOU WILL PAY A REDEMPTION FEE OF 2.0% OF THE VALUE OF THE SHARES
     SOLD.

8. HOW ARE FUND DISTRIBUTIONS MADE AND TAXED?

        International  Discovery 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 that the fund held the securities that were
     sold. Fund  shareholders may also 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.

     employer-sponsored retirement plan or financial intermediary,  your ability
     to purchase shares of the fund,  exchange them for shares or 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 Services Representative at 1-800-345-3533.

                             TWENTIETH CENTURY GROUP

[front cover]


                                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 managers use 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.  Our  growth  strategy  is an  aggressive
     strategy that pursues superior long-term returns for fund shareholders.  We
     call this growth strategy "accelerating earnings and revenues."

        Using American Century's extensive computer database, the 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.  Emerging  Markets  will
     have at least 65% of its assets  invested at all times in  emerging  market
     companies.

        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 risk of an  inter-national  portfolio.  For this reason,  the
     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
     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 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 for them.  If you
     sell your shares  when the value is less than the price you paid,  you will
     lose money. Additionally,  an investment in the fund is not a bank deposit,
     nor is it insured 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 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 are
     explained in detail in the fund's prospectus, summary of which is set forth
     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  could  also  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,  are generally  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 could exert forces which could


EMERGING MARKETS                                    AMERICAN CENTURY INVESTMENTS


          cause the value of the fund's investments to decrease.  The fund could
          also 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
          government  regulation  and oversight.  Foreign  markets may also 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

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 $10,000.  If the value of your account
     falls below the 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 may also  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?

        The fund generally 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  may
     also 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.

9. WHAT SERVICES ARE AVAILABLE?

        American Century offers several ways to make it easier for you to manage

        You may 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 Services Representative at 1-800-345-3533.
