                          AMERICAN CENTURY INVESTMENTS

                        CALIFORNIA TAX-FREE MONEY MARKET

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        California  Tax-Free  Money Market  seeks  safety of principal  and high
     current income that is exempt from California and federal income taxes.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund buys high-quality,  cash equivalent debt securities with income
     payments exempt from California and federal income taxes. Cities,  counties
     and other  municipalities in California  usually issue these securities for
     public projects.

        The fund also buys some  high-quality,  cash  equivalent debt securities
     whose payments are exempt from California and regular federal income taxes,
     but not the federal  alternative  minimum tax.  Cities,  counties and other
     municipalities in California usually issue these securities (called private
     activity bonds) to fund for-profit private projects,  such as hospitals and
     athletic  stadiums.  No more than 20% of the  fund's  total  assets  may be
     invested in these securities.

        The weighted  average  maturity of the fund is expected to be 90 days or
     less.

        Additional   information   about  California   Tax-Free  Money  Market'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?

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

    *Although the fund seeks to preserve the value of your  investment  at $1.00
     per share, it is possible to lose money by investing in the fund.

    *Because   cash-equivalent   securities  are  among  the  safest  securities
     available,  the  interest  they pay is among the lowest  for  income-paying
     securities.  Accordingly,  the yield on this fund will likely be lower than
     funds that invest in longer-term or lower-quality securities.

    *Some of the fund's income may be subject to the federal alternative minimum
     tax.

    *Because the fund invests primarily in California municipal  securities,  it
     will be sensitive to events that affect  California's  economy.  California
     Tax-Free  Money  Market  may have a higher  level of risk than  funds  that
     invest in a larger universe of securities.

        In summary,  California  Tax-Free Money Market is intended for investors
     who seek safety of principal  and high  current  income that is exempt from
     California  and federal income taxes through a municipal  securities  fund,
     and who are  willing  to  accept  the  risks  associated  with  the  fund's
     investment strategy.

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

        There  are no sales  loads,  fees or other  charges  to buy fund  shares
     directly from American Century, to reinvest dividends in additional shares,
     to exchange into the Investor Class shares of other American Century 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                              0.50%(1)
          Distribution and Service (12b-1) Fees       None
          Other Expenses(2)                           0.00%
          Total Annual Fund Operating Expenses        0.50%

        (1)Based  on assets  at  August  31,  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 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
           ------------------------------------------------
             $51        $160           $279          $627

               Of course,  actual costs may be higher or lower. Use this example

                        CALIFORNIA MUNICIPAL MONEY MARKET

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        California  Municipal  Money Market  seeks safety of principal  and high
     current income that is exempt from  California  and regular  federal income
     taxes.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund buys high-quality,  cash-equivalent debt securities with income
     payments exempt from  California and regular federal income taxes.  Cities,
     counties  and  other  municipalities  in  California  usually  issue  these
     securities for public projects.

        The fund also buys high-quality,  cash-equivalent  debt securities whose
     payments are exempt from California and regular  federal income taxes,  but
     not the  federal  alternative  minimum  tax.  Cities,  counties  and  other
     municipalities in California usually issue these securities (called private
     activity bonds) to fund for-profit private projects,  such as hospitals and
     athletic stadiums.

        The weighted  average  maturity of the fund is expected to be 90 days or
     less.

        Additional   information  about  California   Municipal  Money  Market'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?

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

    *Although the fund seeks to preserve the value of your  investment  at $1.00
     per share, it is possible to lose money by investing in the fund.

    *Because   cash-equivalent   securities  are  among  the  safest  securities
     available,  the  interest  they pay is among the lowest  for  income-paying
     securities.  Accordingly,  the yield on this fund will likely be lower than
     funds that invest in longer-term or lower-quality securities.

    *Some or all of the fund's income may be subject to the federal  alternative
     minimum tax.

    *Because the fund invests primarily in California municipal  securities,  it
     will be sensitive to events that affect  California's  economy.  California
     Municipal  Money  Market  may have a higher  level of risk than  funds that
     invest in a larger universe of securities.

        In summary,  California Municipal Money Market is intended for investors
     who seek safety of principal  and high  current  income that is exempt from
     California and regular federal income taxes through a municipal  securities
     fund,  and who are willing to accept the risks  associated  with the fund's
     investment strategy.

     employer-sponsored retirement plan or financial intermediary,  your ability

     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.

                        CALIFORNIA LIMITED-TERM TAX-FREE

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        California  Limited-Term  Tax-Free  seeks safety of  principal  and high
     current income that is exempt from California and federal income taxes.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund buys quality,  short-term  debt securities with income payments
     exempt from California and federal income taxes. Cities, counties and other
     municipalities  in  California  usually issue these  securities  for public
     projects.

        The fund  also buys  some  quality,  short-term  debt  securities  whose
     payments are exempt from California and regular  federal income taxes,  but
     not the  federal  alternative  minimum  tax.  Cities,  counties  and  other
     municipalities in California usually issue these securities (called private
     activity bonds) to fund for-profit private projects,  such as hospitals and
     athletic  stadiums.  No more than 20% of the  fund's  total  assets  may be
     invested in these securities.

        The fund may also use  futures  contracts  and  options  to  pursue  its
     investment objective.

        During  unusual  market  conditions,  the  fund is  permitted  to keep a
     significant  amount of its assets in cash or cash equivalents.  If it does,
     it may not  achieve  its  investment  objective  and may  generate  taxable
     income.

        The weighted  average  maturity of the fund is expected to be five years
     or less.

        Additional   information   about  California   Limited-Term   Tax-Free'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?

    *When  interest  rates  change,  the fund's  share  value will be  affected.
     Generally,  when interest  rates rise, the fund's share value will decline.
     The opposite is true when interest  rates  decline.  The interest rate risk
     for  California  Limited-Term  Tax-Free  is higher than for funds that have
     shorter weighted average maturities, such as money market funds.

    *The fund may  invest in  securities  rated in the lowest  investment  grade
     category  (e.g.,  Baa or BBB).  The  issuers of these  securities  are more
     likely to have problems making interest and principal payments.

    *Some of the fund's income may be subject to the federal alternative minimum
     tax.

    *Because the fund invests primarily in California municipal  securities,  it
     will be sensitive to events that affect  California's  economy.  California
     Limited-Term  Tax-Free  may have a higher  level of risk  than  funds  that
     invest in a larger universe of securities.

    *As  with  all  funds,  at any  given  time  the  value  of your  shares  of
     California  Limited-Term  Tax-Free 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  or any  other
     government agency.

        In summary,  California  Limited-Term Tax-Free is intended for investors
     who seek safety of principal  and high  current  income that is exempt from
     California  and federal income taxes through a municipal  securities  fund,
     and who are  willing  to  accept  the  risks  associated  with  the  fund's
     investment strategy.

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

        There  are no sales  loads,  fees or other  charges  to buy fund  shares
     directly from American Century, to reinvest dividends in additional shares,
     to exchange into the Investor Class shares of other American Century 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                                 0.51%(1)
          Distribution and Service (12b-1) Fees          None
          Other Expenses(2)                              0.01%
          Total Annual Fund Operating Expenses           0.52%

        (1)Based  on assets  at  August  31,  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 OF HYPOTHETICAL FUND COSTS
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem all of your shares at the end of the periods shown below 
             * earn 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
          ----------------------------------------------
           $ 53        $167         $290         $652

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

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        California Intermediate-Term Tax-Free seeks safety of principal and high
     current income that is exempt from California and federal income taxes.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund buys quality,  intermediate-term  debt  securities  with income
     payments exempt from California and federal income taxes. Cities,  counties
     and other  municipalities in California  usually issue these securities for
     public projects.

        The fund also buys some quality, intermediate-term debt securities whose
     payments are exempt from California and regular  federal income taxes,  but
     not the  federal  alternative  minimum  tax.  Cities,  counties  and  other
     municipalities in California usually issue these securities (called private

     significant  amount of its assets in cash or cash equivalents.  If it does,
     it may not  achieve  its  investment  objective  and may  generate  taxable
     income.

        The weighted average maturity of the fund is expected to be between five
     and 10 years.

        Additional  information  about California  Intermediate-Term  Tax-Free'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

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

    *When  interest  rates  change,  the fund's  share  value will be  affected.
     Generally,  when interest  rates rise, the fund's share value will decline.
     The opposite is true when interest  rates  decline.  The interest rate risk
     for  California  Intermediate-Term  Tax-Free  is higher than for funds that
     have  shorter  weighted  average  maturities,  such  as  money  market  and
     short-term bond funds.

    *The fund may  invest in  securities  rated in the lowest  investment  grade
     category  (e.g.,  Baa or BBB).  The  issuers of these  securities  are more
     likely to have problems making interest and principal payments.

     Intermediate-Term  Tax-Free may have a higher level of risk than funds that
     invest in a larger universe of securities.

    *As  with  all  funds,  at any  given  time  the  value  of your  shares  of
     California  Intermediate-Term  Tax-Free  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  or any  other
     government agency.

        In  summary,  California  Intermediate-Term  Tax-Free  is  intended  for
     investors  who seek safety of  principal  and high  current  income that is
     exempt  from  California  and  federal  income  taxes  through a  municipal
     securities  fund, and who are willing to accept the risks  associated  with
     the fund's investment strategy.

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

        There  are no sales  loads,  fees or other  charges  to buy fund  shares
     directly from American Century, to reinvest dividends in additional shares,
     to exchange into the Investor Class shares of other American Century 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                                 0.51%(1)
         Distribution and Service (12b-1) Fees          None
         Other Expenses(2)                              0.00%
         Total Annual Fund Operating Expenses           0.51%

       (1)Based  on assets  at  August  31,  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 OF HYPOTHETICAL FUND COSTS
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem all of your shares at the end of the periods shown below 
             * earn 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
          ----------------------------------------------
           $52         $163         $285          $640

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

                          AMERICAN CENTURY INVESTMENTS

                          CALIFORNIA LONG-TERM TAX-FREE

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        California Long-Term Tax-Free seeks safety of principal and high current
     income that is exempt from California and federal income taxes.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund buys quality,  long-term debt  securities  with income payments
     exempt from California and federal income taxes. Cities, counties and other
     municipalities  in  California  usually issue these  securities  for public
     projects.

        The fund  also  buys  some  quality,  long-term  debt  securities  whose
     payments are exempt from California and regular  federal income taxes,  but
     not the  federal  alternative  minimum  tax.  Cities,  counties  and  other
     municipalities in California usually issue these securities (called private
     activity bonds) to fund for-profit private projects,  such as hospitals and
     athletic  stadiums.  No more than 20% of the  fund's  total  assets  may be
     invested in these securities.

        The fund may also use  futures  contracts  and  options  to  pursue  its
     investment objective.

        During  unusual  market  conditions,  the  fund is  permitted  to keep a
     significant  amount of its assets in cash or cash equivalents.  If it does,
     it may not  achieve  its  investment  objective  and may  generate  taxable
     income.

        The weighted  average maturity of the fund is expected to be 10 years or
     longer.

        Additional information about California Long-Term Tax-Free'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?

    *When  interest  rates  change,  the fund's  share  value will be  affected.
     Generally,  when interest  rates rise, the fund's share value will decline.
     The opposite is true when interest  rates  decline.  The interest rate risk
     for  California  Long-Term  Tax-Free  is higher  than for  funds  that have
     shorter  weighted average  maturities,  such as money market and short-term
     and intermediate-term bond funds.

    *The fund may  invest in  securities  rated in the lowest  investment  grade
     category  (e.g.,  Baa or BBB).  The  issuers of these  securities  are more
     likely to have problems making interest and principal payments.

    *Some of the fund's income may be subject to the federal alternative minimum
     tax.

    *Because the fund invests primarily in California municipal  securities,  it
     will be sensitive to events that affect  California's  economy.  California
     Long-Term  Tax-Free  may have a higher level of risk than funds that invest
     in a larger universe of securities.

    *As  with  all  funds,  at any  given  time  the  value  of your  shares  of
     California  Long-Term Tax-Free 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  or any  other
     government agency.

        In summary,  California Long-Term Tax-Free is intended for investors who
     seek  safety of  principal  and high  current  income  that is exempt  from
     California  and federal income taxes through a municipal  securities  fund,
     and who are  willing  to  accept  the  risks  associated  with  the  fund's
     investment strategy.

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

        There  are no sales  loads,  fees or other  charges  to buy fund  shares
     directly from American Century, to reinvest dividends in additional shares,
     to exchange into the Investor Class shares of other American Century 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                                 0.51%(1)

          Total Annual Fund Operating Expenses           0.51%

        (1)Based  on assets  at  August  31,  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 OF HYPOTHETICAL FUND COSTS

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

          ------------------------------------------------
           $52         $163          $285           $640

                          AMERICAN CENTURY INVESTMENTS

                         CALIFORNIA HIGH-YIELD MUNICIPAL

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        California High-Yield Municipal seeks high current income that is exempt
     from California and regular federal income taxes.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund buys long- and  intermediate-term  debt  securities with income
     payments exempt from  California and regular federal income taxes.  Cities,
     counties  and  other  municipalities  in  California  usually  issue  these
     securities for public projects.

        The fund also may buy long- and intermediate-term  debt securities whose
     payments are exempt from California and regular  federal income taxes,  but
     not the  federal  alternative  minimum  tax.  Cities,  counties  and  other
     municipalities in California usually issue these securities (called private
     activity bonds) to fund for-profit private projects,  such as hospitals and
     athletic  stadiums.  Between 10% and 30% of the fund's  total assets may be
     invested in these securities.

        The fund buys securities  that are considered  below  investment  grade,
     including  so-called "junk bonds." Issuers of these  securities  often have
     short financial histories or have questionable credit.

        The fund also may use  futures  contracts  and  options  to  pursue  its
     investment objective.

        During  unusual  market  conditions,  the  fund is  permitted  to keep a
     significant  amount of its assets in cash or cash equivalents.  If it does,
     it may not  achieve  its  investment  objective  and may  generate  taxable
     income.

        The weighted  average maturity of the fund is expected to be 10 years or
     longer.

        Additional   information   about   California   High-Yield   Municipal's
     investments is available in its annual and  semi-annual  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?

    *When  interest  rates  change,  the fund's  share  value will be  affected.
     Generally,  when interest  rates rise, the fund's share value will decline.
     The opposite is true when interest  rates  decline.  The interest rate risk
     for  California  High-Yield  Municipal  is higher  than for funds that have
     shorter  weighted average  maturities,  such as money market and short-term
     and intermediate-term bond funds.

    *The fund may invest in securities rated below investment  grade,  including
     bonds that are in technical or monetary default. By definition, the issuers
     of many of these  securities  have had, and may continue to have,  problems
     making interest and principal payments.

    *The fund's  investments often have high credit risk. The fund's share value
     may  fluctuate  significantly  more than other bond funds  because the fund
     invests in lower-rated debt securities.

    *Some or all of the fund's income may be subject to the federal  alternative
     minimum tax.

    *Because the fund invests primarily in California municipal  securities,  it
     will be sensitive to events that affect  California's  economy.  California
     High-Yield Municipal may have a higher level of risk than funds that invest
     in a larger universe of securities.

    *As  with  all  funds,  at any  given  time  the  value  of your  shares  of
     California  High-Yield  Municipal  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  or any  other
     government agency.

        In summary,  California  High-Yield  Municipal is intended for investors
     who seek high  current  income that is exempt from  California  and regular
     federal  income  taxes  through a municipal  securities  fund,  and who are
     willing to accept the risks associated with the fund's investment strategy.

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

        There  are no sales  loads,  fees or other  charges  to buy fund  shares
     directly from American Century, to reinvest dividends in additional shares,
     to exchange into the Investor Class shares of other American Century 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                                 0.54%(1)
          Distribution and Service (12b-1) Fees          None
          Other Expenses(2)                              0.00%
          Total Annual Fund Operating Expenses           0.54%

        (1)Based  on assets  at  August  31,  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 OF HYPOTHETICAL FUND COSTS
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem all of your shares at the end of the periods shown below 
             * earn 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
           -----------------------------------------------
            $55         $173         $301         $676

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

     employer-sponsored retirement plan or financial intermediary,  your ability

                          AMERICAN CENTURY INVESTMENTS

                           CALIFORNIA INSURED TAX-FREE

1. WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

        California  Insured  Tax-Free seeks safety of principal and high current
     income that is exempt from  California  and federal  income  taxes  through
     investment in insured California municipal securities.

2. WHAT IS THE FUND'S INVESTMENT STRATEGY?

        The fund buys quality,  long-term  insured debt  securities  with income
     payments exempt from California and federal income taxes. Cities,  counties
     and other  municipalities in California  usually issue these securities for
     public projects.

        The fund also buys some quality, long-term insured debt securities whose
     payments are exempt from California and regular  federal income taxes,  but
     not the  federal  alternative  minimum  tax.  Cities,  counties  and  other
     municipalities in California usually issue these securities (called private
     activity bonds) to fund for-profit private projects,  such as hospitals and
     athletic  stadiums.  No more than 20% of the  fund's  total  assets  may be
     invested in these securities.

        The fund's investments are insured. This is significant because

    *   the credit  risk is less than for funds that  invest in  long-term  debt
        securities without insurance

    *   potential  income is lower than for funds that invest in long-term  debt
        securities without insurance

        A debt  security's  insurance  cannot be cancelled and  guarantees  that
     interest and other payments will be made as scheduled.

        The weighted  average maturity of the fund is expected to be 10 years or
     longer.

        The fund also may use  futures  contracts  and  options  to  pursue  its
     investment objective.

        During  unusual  market  conditions,  the  fund is  permitted  to keep a
     significant  amount of its assets in cash or cash equivalents.  If it does,
     it may not  achieve  its  investment  objective  and may  generate  taxable
     income.

        Additional  information about California Insured Tax-Free'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?

    *When  interest  rates  change,  the fund's  share  value will be  affected.
     Generally,  when interest  rates rise, the fund's share value will decline.
     The opposite is true when interest  rates  decline.  The interest rate risk
     for California  Insured Tax-Free is higher than for funds that have shorter
     weighted  average  maturities,  such as money  market  and  short-term  and
     intermediate-term bond funds.

    *The fund may  invest in  securities  rated in the lowest  investment  grade
     category  (e.g.,  Baa or BBB).  The  issuers of these  securities  are more
     likely to have problems making interest and principal payments.

    *Some of the fund's income may be subject to the federal alternative minimum
     tax.

    *Because the fund invests primarily in California municipal  securities,  it
     will be sensitive to events that affect  California's  economy.  California
     Insured  Tax-Free may have a higher level of risk than funds that invest in
     a larger universe of securities.

    *As  with  all  funds,  at any  given  time  the  value  of your  shares  of
     California  Insured  Tax-Free  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  or any  other
     government agency.


CALIFORNIA INSURED TAX-FREE                         AMERICAN CENTURY INVESTMENTS


        In summary,  California  Insured  Tax-Free is intended for investors who
     seek  safety of  principal  and high  current  income  that is exempt  from
     California  and federal income taxes through a municipal  securities  fund,
     and who are  willing  to  accept  the  risks  associated  with  the  fund's
     investment strategy.

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

        There  are no sales  loads,  fees or other  charges  to buy fund  shares
     directly from American Century, to reinvest dividends in additional shares,
     to exchange into the Investor Class shares of other American Century 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                                 0.51%(1)
          Distribution and Service (12b-1) Fees          None

          Total Annual Fund Operating Expenses           0.51%

        (1)Based  on assets  at  August  31,  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 OF HYPOTHETICAL FUND COSTS
             Assuming you . . .
             * invest $10,000 in the fund
             * redeem all of your shares at the end of the periods shown below 
             * earn 5% return each year 
             * incur the same operating expenses shown above

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 $5,000.  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 may also  exchange  your  shares in  California
     Insured  Tax-Free  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?

        California  Insured Tax-Free pays  distributions of substantially all of
     its income monthly.  Distributions will generally be exempt from California
     and  federal  income  taxes.  Some of the fund's  income may,  however,  be
     subject to the federal  alternative  minimum tax.  Consult your tax advisor
     for  information  about whether you are subject to the federal  alternative
     minimum tax.  Distributions  are  reinvested  automatically  in  additional
     shares unless you choose another option.

     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.
