EXAMPLE:
You would pay the following expenses on a                   1 year      $   9
$1,000 investment, assuming a 5% annual return and         3 years         28
redemption at the end of each time period:                 5 years         48
                                                          10 years        107

(1) Redemption proceeds sent by wire are subject to a $10 processing fee.

(2) A portion of the management fee may be paid by American  Century  Investment
    Management,  Inc. (the "Manager") to unaffiliated  third parties who provide
    recordkeeping and administrative  services that would otherwise be performed
    by  an   affiliate  of  the  Manager.   See   "Management   -  Transfer  and
    Administrative Services," page 21.

  The purpose of the above table is to help you understand the various costs and
expenses  that you,  as a  shareholder,  will bear  directly  or  indirectly  in
connection  with an  investment  in the class of shares of the American  Century
Fund  offered  by  this   Prospectus.   The  example  set  forth  above  assumes
reinvestment  of all  dividends and  distributions  and uses a 5% annual rate of
return as required by SEC regulations.
    

  NEITHER  THE 5%  RATE OF  RETURN  NOR  THE  EXPENSES  SHOWN  ABOVE  SHOULD  BE
CONSIDERED  INDICATIONS OF PAST OR FUTURE  RETURNS AND EXPENSES.  ACTUAL RETURNS
AND EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

   
  The shares  offered by this  Prospectus  are Investor Class shares and have no
up-front or deferred sales charges,  commissions, or 12b-1 fees. The Fund offers
one other class of shares,  primarily  to  institutional  investors,  that has a
different  fee  structure  than the Investor  Class.  The  difference in the fee
structures  among the classes is the result of their separate  arrangements  for
shareholder  and  distribution  services and not the result of any difference in
amounts  charged  by  the  Manager  for  core  investment   advisory   services.
Accordingly,  the core  investment  advisory  expenses  do not vary by class.  A
difference in fees will result in different  performance for those classes.  For
additional information about the various classes, see "Further Information About
American Century," page 22.

                        INFORMATION REGARDING THE FUND

INVESTMENT POLICIES OF THE FUND

    The Fund has adopted certain  investment  restrictions that are set forth in
the  Statement of Additional  Information.  Those  restrictions,  as well as the
investment objective of the Fund identified on page 2 of this Prospectus and any
other investment  policies  designated as "fundamental" in this Prospectus or in
the Statement of Additional  Information,  cannot be changed without shareholder
approval.  The Fund has implemented additional investment policies and practices
to guide its  activities  in the  pursuit  of its  investment  objective.  These
policies and practices,  which are described throughout this Prospectus, are not
designated  as  fundamental  policies  and may be  changed  without  shareholder
approval.

    For an explanation of the  securities  ratings  referred to in the following
discussion, see "Other Information" in the Statement of Additional Information.

INVESTMENT OBJECTIVE

   
    The Fund seeks to provide high current  income and capital  appreciation  by
investing in high-quality,  nondollar-denominated  government and corporate debt
securities  outside the United States.  There is no assurance that the Fund will
achieve its investment  objective.  The Fund is a  "non-diversified  company" as
defined in the Investment  Company Act of 1940 (the  "Investment  Company Act"),
which means that the proportion of the Fund's assets that may be invested in the
securities of a single issuer is not limited by the Investment Company Act.
    

    The Fund may be appropriate for U.S. investors who:

    o   Want to protect their income against a decline in the  purchasing  power
        of the U.S. dollar relative to that of foreign currencies.

    o   Want to  diversify  their  investments  beyond  U.S.  dollar-denominated
        securities and interest rate exposure.

    As market conditions change (i.e.,  interest rate,  political,  and economic
changes  occur),  the Fund's  value will vary.  The Fund's  performance  will be
affected by currency values,  foreign  economies,  and other foreign  investment
factors.

INTERNATIONAL SUBADVISOR

    J.P. Morgan  Investment  Management Inc.  ("JPMIM") is the Fund's subadvisor
and is responsible for its day-to-day operations.  JPMIM is headquartered in New
York and maintains offices in most of the world's financial  centers,  including
London and Frankfurt.

INVESTMENT STRATEGY

    JPMIM selects the Fund's  investments  by using a combination of fundamental
research  and bond and  currency  valuation  models.  The  following  is a brief
summary of factors considered by JPMIM in selecting the Fund's investments:

    o   ECONOMIC/POLITICAL FUNDAMENTALS: JPMIM evaluates each country's economic
        climate and political discipline for controlling deficits and inflation.

    o   EXPECTED RETURN:  Using economic forecasts,  JPMIM projects the expected
        return for each country.

    o   RELATIVE   VALUE:   By  contrasting   expected  risks  and  returns  for
        investments in each country,  JPMIM selects those countries  expected to
        produce the best return at reasonable risk.

   
    The Fund's  investments  may  include  but shall not be limited to: (1) Debt
obligations issued or guaranteed by (a) a foreign sovereign government or one of
its agencies, authorities, instrumentalities or political subdivisions including
a foreign state, province or municipality,  and (b) supranational  organizations
such as the World Bank, Asian  Development Bank,  European  Investment Bank, and
European Economic Community;  (2) Debt obligations of (a) foreign banks and bank
holding  companies,  and (b) domestic banks and  corporations  issued in foreign
currencies;  and (3) Foreign corporate debt securities and commercial paper. All
of these  investments must satisfy the credit quality  standards (i.e.,  "AA" or
higher) established by the Trustees of the Fund.
    


6   INFORMATION REGARDING THE FUND                  AMERICAN CENTURY INVESTMENTS


   
    Such  securities may take a variety of forms  including  those issued in the
local currency of the issuer,  Euro bonds, and bonds denominated in the European
currencies or ECUs. ECUs are a composite currency consisting of fixed amounts of
currency of European  Economic  Community member countries.  Normally,  the Fund
will only purchase bonds denominated in foreign currencies.

PORTFOLIO COMPOSITION

    Under  normal  market  conditions,  the Fund will invest at least 65% of its
total  assets in bonds  issued or  guaranteed  by foreign  governments  or their
agencies and by foreign authorities,  provinces and municipalities. The Fund may
invest  up to 35% of its total  assets  in  high-quality  (i.e.,  rated  "AA" or
higher) foreign corporate debt securities.

    The Fund's credit quality  requirements  effectively  limit the countries in
which the Fund may invest.  As of the date of this Prospectus,  the Fund expects
to invest  in the  securities  of  issuers  located  in and  governments  of the
following countries:  Australia,  Austria,  Belgium,  Canada, Denmark,  Finland,
France, Germany, Ireland, Japan, Liechtenstein, Luxembourg, Netherlands, Norway,
Portugal, Singapore, Spain, Sweden, Switzerland,  Taiwan, and United Kingdom. To
limit the  possibility  that the Fund will become unduly  concentrated in Japan,
the Fund currently  limits its investment in issuers located in Japan to no more
than 15% of total assets.
    

CURRENCY MANAGEMENT

    The rate of exchange between U.S. dollars and foreign currencies fluctuates,
which  results  in gains  and  losses to the Fund.  Even if the  Fund's  foreign
security  holdings perform well, an increase in the value of the dollar relative
to the currencies in which  portfolio  securities are denominated can offset net
investment income.

    Because  the  Fund is  designed  for U.S.  investors  seeking  currency  and
interest  rate  diversification,  JPMIM  limits  its use of  hedging  strategies
intended  to  minimize  the effect of currency  fluctuations.  Although  hedging
strategies (if they are successful)  reduce exchange rate risk, they also reduce
the potential for share price appreciation when foreign  currencies  increase in
value relative to the U.S. dollar.

    When JPMIM  considers the U.S.  dollar to be attractive  relative to foreign
currencies,  as  much as 25% of the  Fund's  total  assets  may be  hedged  into
dollars. For temporary defensive purposes and under extraordinary  circumstances
(such as significant political events), more than 25% of the Fund's total assets
may be hedged in this manner.

   
    In managing the Fund's  currency  exposure,  JPMIM will buy and sell foreign
currencies  regularly,  either in the spot  (i.e.,  cash)  market or the forward
market.  Forward foreign currency exchange contracts  ("forward  contracts") are
individually  negotiated and privately  traded between currency traders (usually
large  commercial  banks)  and  their  customers.  In  most  cases,  no  deposit
requirements  exist,  and these  contracts  are  traded  at a net price  without
commission.  Forward  contracts  involve an  obligation  to  purchase  or sell a
specific  currency at an  agreed-upon  price on a future  date.  Most  contracts
expire in less than one year.  The Fund may also use  futures  and  options  for
currency  management  purposes.  The Fund will not use  futures  and options for
speculative  purposes.  For more information on futures and options,  please see
"Interest Rate Futures Contracts and Options Thereon" on page 9.
    

RISK FACTORS

   
INVESTING IN FOREIGN SECURITIES

    Investing in securities of foreign issuers generally  involves greater risks
than investing in the securities of domestic  companies.  As with any investment
in  securities,  the value of an  investment in the Fund can decrease as well as
increase,  depending  upon a variety of factors  which may affect the values and
income  generated by the Fund's  portfolio  securities.  Investments in the Fund
should  not  be  considered  a  complete  investment  program  and  may  not  be
appropriate for an individual with limited investment resources or who is unable
to tolerate  fluctuations  in the value of the investment.  Potential  investors
should carefully consider the following factors:

    Currency Risk. The value of the foreign  investments held by the Fund may be
significantly  affected by changes in currency  exchange rates. The dollar value
of a foreign  security  generally  decreases  when the value of the dollar rises
against the foreign cur-


PROSPECTUS                                    INFORMATION REGARDING THE FUND   7


rency in which the security is denominated  and tends to increase when the value
of the dollar falls against such currency. In addition, the value of Fund assets
may be affected by losses and other  expenses  incurred  in  converting  between
various  currencies  in order to purchase  and sell  foreign  securities  and by
currency  restrictions,  exchange control regulation,  currency devaluations and
political developments.

    Political and Economic Risk. The economies of many of the countries in which
the Fund invests are not as  developed  as the economy of the United  States and
may  be  subject  to  significantly   different  forces.   Political  or  social
instability,  expropriation,  nationalization,  or  confiscatory  taxation,  and
limitations on the removal of funds or other assets, could also adversely affect
the value of  investments.  Further,  the Fund may encounter  difficulties or be
unable to pursue legal remedies or obtain judgments in foreign courts.

    Regulatory  Risk.  Foreign  companies  are  generally  not  subject  to  the
regulatory  controls  imposed on U.S.  issuers  and, in  general,  there is less
publicly available  information about foreign securities than is available about
domestic  securities.   Many  foreign  companies  are  not  subject  to  uniform
accounting,   auditing  and  financial   reporting   standards,   practices  and
requirements  comparable to those applicable to domestic companies.  Income from
foreign  securities owned by the Fund may be reduced by a withholding tax at the
source which would reduce dividend income payable to shareholders.  See "TAXES,"
page 19.

    Market And Trading Risk.  Brokerage  commission rates in foreign  countries,
which are generally  fixed rather than subject to  negotiation  as in the United
States, are likely to be higher. The securities markets in many of the countries
in which the Fund invest will have  substantially  less trading  volume than the
principal U.S. markets.  As a result,  the securities of some companies in these
countries may be less liquid and more volatile than comparable U.S.  securities.
Furthermore,  one securities  broker may represent all or a significant  part of
the trading  volume in a particular  country,  resulting in higher trading costs
and decreased liquidity due to a lack of alternative trading partners.  There is
generally less government regulation and supervision of foreign stock exchanges,
brokers  and  issuers  which  may  make  it  difficult  to  enforce  contractual
obligations.

    Clearance  and  Settlement  Risk.   Foreign  securities  markets  also  have
different clearance and settlement procedures, and in certain markets there have
been times  when  settlements  have been  unable to keep pace with the volume of
securities  transactions,  making it  difficult  to conduct  such  transactions.
Delays in clearance and settlement could result in temporary periods when assets
of the Fund are uninvested and no return is earned thereon. The inability of the
Fund to  make  intended  security  purchases  due to  clearance  and  settlement
problems  could  cause  the Fund to miss  attractive  investment  opportunities.
Inability to dispose of portfolio  securities  due to clearance  and  settlement
problems could result either in losses to the Fund due to subsequent declines in
value of the  portfolio  security or, if the Fund has entered into a contract to
sell the security, liability to the purchaser.

CREDIT QUALITY

    Under normal  circumstances,  the Fund invests  exclusively in securities of
issuers rated high quality,  nondollar-denominated government and corporate debt
securities  outside the United  States.  "High  quality" means that the security
must be rated AA or higher, at the time of purchase,  by a nationally recognized
statistical rating agency or considered by JPMIM to be of comparable quality. If
a rating  agency  downgrades a security held by the Fund or judges a security to
be less than AA  quality,  the  security  would be sold as quickly  as  possible
without unnecessarily destabilizing the Fund's share price or yield.
    

DOLLAR-WEIGHTED AVERAGE MATURITY

    The Fund's dollar-weighted average portfolio maturity ranges from two to ten
years.

OTHER INVESTMENT PRACTICES, THEIR CHARACTERISTICS AND RISKS

    For additional  information  regarding the investment practices of the Fund,
see the Statement of Additional Information.

PORTFOLIO TURNOVER

    The  portfolio  turnover  rates  of the  Fund  are  shown  in the  Financial
Highlights table on page 5 of this Prospectus.

    Investment  decisions  to  purchase  and sell  securities  are  based on the
anticipated contribution of the secu-


8   INFORMATION REGARDING THE FUND                  AMERICAN CENTURY INVESTMENTS


rity in question to the Fund's objectives. The Manager believes that the rate of
portfolio  turnover is  irrelevant  when it or JPMIM  determines  a change is in
order to  achieve  those  objectives  and,  accordingly,  the  annual  portfolio
turnover rate cannot be accurately predicted.

    The  portfolio  turnover of the Fund may be higher than other  mutual  funds
with   similar   investment   objectives.   Higher   turnover   would   generate
correspondingly  greater  brokerage  commissions,  which is a cost that the Fund
pays  directly.  Portfolio  turnover  may also affect the  character  of capital
gains,  if any,  realized and distributed by the Fund since  short-term  capital
gains are taxable as ordinary income.

    Transaction  costs are normally higher for foreign  securities than for U.S.
securities; therefore, the Fund's anticipated portfolio turnover rate may have a
larger  negative  impact  on total  return  than it  would if the Fund  invested
primarily or exclusively in U.S. securities.

WHEN-ISSUED AND FORWARD  COMMITMENT AGREEMENTS

    The Fund may sometimes purchase new issues of securities on a when-issued or
forward  commitment  basis when, in the opinion of the Manager,  such  purchases
will  further the  investment  objective of the Fund.  The price of  when-issued
securities  is  established  at the time the  commitment  to  purchase  is made.
Delivery  of and  payment for these  securities  typically  occurs 15 to 45 days
after the commitment to purchase. Market rates of interest on debt securities at
the time of  delivery  may be higher or lower than those  contracted  for on the
security.  Accordingly, the value of the security may decline prior to delivery,
which could result in a loss to the Fund.

INTEREST RATE FUTURES CONTRACTS AND OPTIONS THEREON

    The Fund may buy or sell  interest rate futures  contracts  relating to debt
securities ("debt futures," i.e., futures relating to indexes on types or groups
of bonds)  and  write or buy put and call  options  relating  to  interest  rate
futures contracts.

    For options sold, the Fund will segregate cash or appropriate  liquid assets
including equity  securities and debt securities of any grade equal to the value
of securities underlying the option unless the option is otherwise covered.

   
    The Fund will  deposit  cash or  appropriate  liquid  assets in a segregated
custodial  account in an amount  equal to the  fluctuating  market value of long
futures  contracts  it has  purchased,  less any  margin  deposited  on its long
position.  It may hold cash or acquire such debt  obligations for the purpose of
making these deposits.
    

    The Fund may use futures and options  transactions to maintain cash reserves
while remaining fully invested,  to facilitate  trading,  to reduce  transaction
costs, or to pursue higher investment  returns when a futures contract is priced
more attractively than its underlying security or index.

   
    Since futures  contracts and options thereon can replicate  movements in the
markets  for the  securities  in which the Fund  invests  without the large cash
investments  required for dealing in such markets,  they may subject the Fund to
greater and more volatile risks than might  otherwise be the case. The principal
risks related to the use of such instruments are (1) the offsetting  correlation
between  movements in the market  price of the  portfolio  investments  (held or
intended) being hedged and in the price of the futures contract or option may be
imperfect;  (2)  possible  lack of a liquid  secondary  market for  closing  out
futures or option  positions;  (3) the need of additional  portfolio  management
skills  and  techniques;  and  (4)  losses  due to  unanticipated  market  price
movements.  For a hedge to be  completely  effective,  the  price  change of the
hedging instrument should equal the price change of the securities being hedged.
Such  equal  price  changes  are not  always  possible  because  the  investment
underlying the hedging  instrument may not be the same  investment that is being
hedged.
    

    The ordinary spreads between prices in the cash and futures markets,  due to
the differences in the nature of those markets,  are subject to distortion.  Due
to the possibility of distortion,  a correct  forecast of general  interest rate
trends by the  Manager  may still not result in a  successful  transaction.  The
Manager  may be  incorrect  in its  expectations  as to the  extent  of  various
interest rate movements or the time span within which the movements take place.

    See the Statement of Additional  Information for further  information  about
these instruments and their risks.


PROSPECTUS                                    INFORMATION REGARDING THE FUND   9


SHORT-TERM INSTRUMENTS

   
    For liquidity  purposes,  the Fund may invest in  high-quality  money market
instruments with remaining  maturities of one year or less. Such instruments may
include  nondollar-denominated   obligations  of  foreign  governments,  foreign
government agencies,  and supranational  organizations,  as well as high-quality
certificates of deposit.
    

    The Fund may also enter into repurchase  agreements,  collateralized by U.S.
government  securities,  with banks or broker-dealers that are deemed to present
minimal credit risk. Credit risk determinations are made by the Manager pursuant
to  guidelines  established  by the Board of Trustees.  A  repurchase  agreement
involves  the purchase of a security  and a  simultaneous  agreement to sell the
security back to the seller at a higher price.  Delays or losses could result if
the other party to the agreement defaults or becomes bankrupt.

   
    The Fund may invest up to 5% of its total  assets in any money  market  fund
Advised by the Manager,  provided that the  investment  is  consistent  with the
Fund's investment policies and restrictions.
    

SECURITIES LENDING

   
    In order  to  realize  additional  income,  the Fund may lend its  portfolio
securities  to  persons  not  affiliated  with  it  and  who  are  deemed  to be
creditworthy.  Such  loans  must be  secured  continuously  by  cash  collateral
maintained on a current basis in an amount at least equal to the market value of
the securities loaned, or by irrevocable letters of credit. During the existence
of the loan,  the Fund must  continue to receive the  equivalent of the interest
and dividends  paid by the issuer on the  securities  loaned and interest on the
investment of the collateral.  The Fund must have the right to call the loan and
obtain the  securities  loaned at any time on five days'  notice,  including the
right to call the loan to enable the Fund to vote the securities.  This practice
could result in a loss or a delay in recovering the Fund's securities.

    The Fund may not lend any  security  or make any other loan if, as a result,
more than 33-1/3% of the Fund's  total assets would be lent to other  parties in
the manner described above.
    

OTHER TECHNIQUES

    JPMIM may buy other types of securities or employ other portfolio management
techniques on behalf of the Fund.  When SEC guidelines  require it to do so, the
Fund will set aside cash or appropriate liquid assets in a segregated account to
cover its  obligations.  See the Statement of Additional  Information for a more
detailed  discussion of these  investments and some of the risks associated with
them.

PERFORMANCE ADVERTISING

   
    From time to time, the Fund may advertise performance data. Fund performance
may be shown  by  presenting  one or more  performance  measurements,  including
cumulative  total return or average  annual total  return,  yield and  effective
yield.  Performance data may be quoted separately for the Investor Class and for
the other class offered by the Fund.
    

    Cumulative  total  return data is computed by  considering  all  elements of
return,  including  reinvestment  of dividends and capital gains  distributions,
over a stated  period of time.  Average  annual  total return is  determined  by
computing  the annual  compound  return over a stated  period of time that would
have  produced  the Fund's  cumulative  total return over the same period if the
Fund's performance had remained constant throughout.

    A  quotation  of yield  reflects  the  Fund's  income  over a stated  period
expressed as a percentage  of the Fund's share  price.  The  effective  yield is
calculated in a similar manner,  but, when annualized,  the income earned by the
investment is assumed to be  reinvested.  The  effective  yield will be slightly
higher  than  the  yield  because  of the  compounding  effect  on  the  assumed
reinvestment.

    Yield is  calculated  by adding  over a 30-day  (or  one-month)  period  all
interest and dividend  income (net of fund  expenses)  calculated  on each day's
market  values,  dividing  this  sum  by  the  average  number  of  Fund  shares
outstanding  during the period, and expressing the result as a percentage of the
Fund's  share  price on the last day of the 30-day (or one  month)  period.  The
percentage is then annualized.  Capital gains and losses are not included in the
calculation.


10   INFORMATION REGARDING THE FUND                 AMERICAN CENTURY INVESTMENTS


   
    Yields are calculated  according to accounting methods that are standardized
in accordance with SEC rules.  Because yield accounting  methods differ from the
methods  used for other  accounting  purposes,  a Fund's yield may not equal the
income  paid on its  shares  or the  income  reported  in the  Fund's  financial
statements.
    

    The Fund may also include in advertisements data comparing  performance with
the performance of non-related  investment media,  published  editorial comments
and performance  rankings compiled by independent  organizations (such as Lipper
Analytical  Services) and  publications  that monitor the  performance of mutual
funds.  Performance information may be quoted numerically or may be presented in
a table,  graph or other  illustration.  In addition,  Fund  performance  may be
compared to well-known indices of market performance.  Fund performance may also
be compared,  on a relative basis,  to the other funds in our fund family.  This
relative  comparison,  which  may be based  upon  historical  or  expected  fund
performance,  volatility  or  other  Fund  characteristics,   may  be  presented
numerically,  graphically or in text.  Fund  performance may also be combined or
blended  with  other  funds in our fund  family,  and that  combined  or blended
performance may be compared to the same indices to which individual funds may be
compared.

    All performance  information  advertised by the Fund is historical in nature
and is not intended to represent or guarantee future results.  The value of Fund
shares when redeemed may be more or less than their original cost.

    As long as you meet any minimum  investment  requirements,  you may exchange
your Fund  shares to our other  funds up to six times per year per  account.  An

before the Fund's net asset  values are  calculated,  which is one hour prior to
the close of the New York Stock Exchange for the


PROSPECTUS                  HOW TO INVEST WITH AMERICAN CENTURY INVESTMENTS   13


funds issued by American  Century Target  Maturities  Trust, and at the close of
the Exchange for all of our other funds.  See "When Share Price is  Determined,"
page 18.

    For any single exchange,  the shares of each fund being acquired must have a
value of at least $100.  However, we will allow investors to set up an Automatic
Exchange Plan between any two funds in the amount of at least $50 per month. See
our Investor Services Guide for further information about exchanges.

    You may direct us in writing  to  exchange  your  shares  from one  American
Century account to another. For additional information,  please see our Investor
Services Guide.

HOW TO REDEEM SHARES

    We will  redeem or "buy back" your shares at any time.  Redemptions  will be
made at the next net asset value determined after a complete  redemption request
is received.

    Please note that a request to redeem shares in an IRA or 403(b) plan must be
accompanied  by an  executed  IRS  Form  W4-P  and a reason  for  withdrawal  as
specified by the IRS.

BY MAIL

    Your  written  instructions  to  redeem  shares  may  be  made  either  by a
redemption form,  which we will send to you upon request,  or by a letter to us.
Certain  redemptions  may require a signature  guarantee.  Please see "Signature
Guarantee," page 15.

BY TELEPHONE

    If you have authorized us to accept telephone  instructions,  you may redeem
your shares by calling an Investor Services Representative.

BY CHECK-A-MONTH

    If you have at least a  $10,000  balance  in your  account,  you may  redeem
shares by  Check-A-Month.  A  Check-A-Month  plan  automatically  redeems enough
shares each month to provide  you with a check in an amount you choose  (minimum
$50). To set up a Check-A-Month  plan,  please call to request our Check-A-Month
brochure.

OTHER AUTOMATIC REDEMPTIONS

    If you have at least a $10,000  balance  in your  account,  you may elect to
make  redemptions  automatically by authorizing us to send funds directly to you
or to your account at a bank or other financial institution. To set up automatic
redemptions, call one of our Investor Services Representatives.

REDEMPTION PROCEEDS

    Please  note that  shortly  after a  purchase  of shares is made by check or
electronic  draft (also known as an ACH draft) from your bank, we may wait up to
15 days or longer to send  redemption  proceeds (to allow your purchase funds to
clear).  No interest is paid on the redemption  proceeds after the redemption is
processed but before your redemption proceeds are sent.

    Redemption proceeds may be sent to you in one of the following ways:

BY CHECK

    Ordinarily,  all  redemption  checks will be made payable to the  registered
owner of the shares and will be mailed only to the  address of record.  For more
information, please refer to our Investor Services Guide.

BY WIRE AND ACH

    You may authorize us to transmit  redemption  proceeds by wire or ACH. These
services will be effective 15 days after we receive the authorization.

    Your bank will usually receive wired funds within 48 hours of  transmission.
Funds transferred by ACH may be received up to seven days after transmission.
Wired funds are subject to a $10 fee to cover bank


14 HOW TO INVEST WITH AMERICAN CENTURY INVESTMENTS  AMERICAN CENTURY INVESTMENTS


wire charges,  which is deducted from  redemption  proceeds.  Once the funds are
transmitted,  the time of receipt and the funds'  availability are not under our
control.

REDEMPTION OF SHARES IN LOW-BALANCE ACCOUNTS

    Whenever  the  shares  held in an  account  have a value  of less  than  the
required  minimum,  a letter will be sent advising you of the necessity to bring
the value of the shares held in the account up to the minimum.  If action is not
taken within 90 days of the letter's  date,  the shares held in the account will
be  redeemed  and  proceeds  from the  redemption  will be sent by check to your
address of record. We reserve the right to increase the investment minimums.

SIGNATURE GUARANTEE

    To protect  your  accounts  from fraud,  some  transactions  will  require a
signature guarantee.  Which transactions will require a signature guarantee will
depend on which  service  options  you elect  when you open  your  account.  For
example, if you choose "In Writing Only," a signature guarantee will be required
when:

    o redeeming more than $25,000; or

    o establishing or increasing a Check-A-Month or automatic transfer on an
      existing account.

    You may obtain a signature  guarantee from a bank or trust  company,  credit
union,  broker-dealer,  securities  exchange or association,  clearing agency or
savings association, as defined by federal law.

    For a more in-depth explanation of our signature guarantee policy, or if you
live outside the United  States and would like to know how to obtain a signature
guarantee, please consult our Investor Services Guide.

    We reserve the right to require a signature guarantee on any transaction, or
to change this policy at any time.

SPECIAL SHAREHOLDER SERVICES

    We offer  several  service  options to make your  account  easier to manage.
These are listed on the account  application.  Please make note of these options
and  elect  the ones  that are  appropriate  for you.  Be aware  that the  "Full
Services" option offers you the most flexibility. You will find more information
about each of these service options in our Investor Services Guide.

    Our special shareholder services include:

AUTOMATED INFORMATION LINE

    We offer an Automated  Information  Line, 24 hours a day, seven days a week,
at 1-800-345-8765.  By calling the Automated Information Line, you may listen to
fund prices,  yields and total return  figures.  You may also use the  Automated
Information  Line to make  investments  into your accounts (if we have your bank
information  on file) and  obtain  your  share  balance,  value and most  recent
transactions.  If you have authorized us to accept telephone  instructions,  you
also may exchange shares from one fund to another via the Automated  Information
Line.  Redemption  instructions  cannot be given via the  Automated  Information
Line.

ONLINE ACCOUNT ACCESS

    You   may   contact   us  24   hours   a  day,   seven   days   a  week   at
www.americancentury.com to access your funds' daily share price, receive updates
on major market indexes and view  historical  performance of your funds.  If you
select "Full  Services" on your  application,  you can use your personal  access
code and  Social  Security  number to view your  account  balances  and  account
activity,  make subsequent investments from your bank account or exchange shares
from one fund to another.

OPEN ORDER SERVICE

    Through our open order  service,  you may  designate a price at which to buy
shares of a variable-priced fund by exchange from one of our money market funds,
or a price at which to sell shares of a variable-priced  fund by exchange to one
of our money market funds.  The  designated  purchase  price must be equal to or
lower, or the designated sale price equal to or higher, than the variable-priced
fund's net asset value at the time the order is placed.  If the designated price
is  met  within  90  calendar   days,  we  will  execute  your  exchange   order
automatically at that price (or better). Open orders not executed within 90 days
will be canceled.

    If the fund you have selected  deducts a distribution  from its share price,
your order  price will be  adjusted  accordingly  so the  distribution  does not
inadvertently trigger an open order transaction on


PROSPECTUS                  HOW TO INVEST WITH AMERICAN CENTURY INVESTMENTS   15


your behalf.  If you close or re-register  the account from which the shares are
to be redeemed, your open order will be canceled.

    Because of their time-sensitive nature, open order transactions are accepted
only by  telephone  or in person.  These  transactions  are  subject to exchange
limitations  described  in  each  fund's  prospectus,  except  that  orders  and
cancellations  received  before 2 p.m.  Central time are effective the same day,
and orders or cancellations received after 2 p.m. Central time are effective the
next business day.

TAX-QUALIFIED RETIREMENT PLANS

    The Fund is available for your  tax-deferred  retirement plan. Call or write
us and request the appropriate forms for:

    o Individual Retirement Accounts ("IRA"s);

    o 403(b) plans for employees of public school systems and non-profit
      organizations; or

    o Profit sharing plans and pension plans for corporations and other
      employers.

    If your IRA and  403(b)  accounts  do not total  $10,000,  each  account  is
subject to an annual $10 fee, up to a total of $30 per year.

    You can also transfer your  tax-deferred  plan to us from another company or
custodian. Call or write us for a Request to Transfer form.

IMPORTANT POLICIES REGARDING YOUR INVESTMENTS

    Every  account is subject to policies  that could  affect  your  investment.
Please refer to the Investor  Services Guide for further  information  about the
policies discussed below, as well as further detail about the services we offer

  (1) We reserve the right for any reason to suspend the  offering of shares for
      a period of time,  or to reject any  specific  purchase  order  (including
      purchases by exchange). Additionally,  purchases may be refused if, in the
      opinion  of the  Manager,  they  are  of a size  that  would  disrupt  the
      management of the Fund.

  (2) We  reserve   the  right  to  make   changes  to  any  stated   investment
      requirements,  including  those that relate to  purchases,  transfers  and
      redemptions.  In  addition,  we may also alter,  add to or  terminate  any
      investor services and privileges.  Any changes may affect all shareholders
      or only certain series or classes of shareholders.

  (3) Shares  being  acquired  must be  qualified  for  sale in  your  state  of
      residence.

  (4) Transactions requesting a specific price and date, other than open orders,
      will be  refused.  Once you have  mailed  or  otherwise  transmitted  your
      transaction instructions to us, they may not be modified or canceled.

  (5) If a transaction  request is made by a  corporation,  partnership,  trust,
      fiduciary, agent or unincorporated  association,  we will require evidence
      satisfactory to us of the authority of the individual making the request.

  (6) We have  established  procedures  designed to assure the  authenticity  of
      instructions  received by telephone.  These procedures  include requesting
      personal  identification  from callers,  recording  telephone  calls,  and
      providing   written   confirmations  of  telephone   transactions.   These
      procedures  are  designed to protect  shareholders  from  unauthorized  or
      fraudulent  instructions.  If we do not employ  reasonable  procedures  to
      confirm the genuineness of instructions,  then we may be liable for losses
      due to unauthorized or fraudulent instructions.  The company, its transfer
      agent and investment  advisor will not be responsible  for any loss due to
      instructions they reasonably believe are genuine.

  (7) All signatures  should be exactly as the name appears in the registration.
      If the owner's name appears in the  registration as Mary Elizabeth  Jones,
      she should sign that way and not as Mary E. Jones.

  (8) Unusual stock market  conditions  have in the past resulted in an increase
      in the number of shareholder telephone calls. If you experience difficulty
      in  reaching  us  during  such  periods,  you may  send  your  transaction
      instructions by mail,  express mail or courier  service,  or you may visit
      one of our Investor  Centers.  You may also use our Automated  Information
      Line if you  have  requested  and  received  an  access  code  and are not
      attempting to redeem shares.

  (9) If  you  fail  to  provide  us  with  the   correct   certified   taxpayer
      identification  number,  we may reduce any  redemption  proceeds by $50 to
      cover the penalty the IRS will impose on us


16 HOW TO INVEST WITH AMERICAN CENTURY INVESTMENTS  AMERICAN CENTURY INVESTMENTS


      for failure to report your correct taxpayer identification number on
      information reports.

 (10) We will perform special inquiries on shareholder  accounts. A research fee
      of $15 per hour may be applied.

REPORTS TO SHAREHOLDERS

    At the  end of  each  calendar  quarter,  we will  send  you a  consolidated
statement that summarizes all of your American Century  holdings,  as well as an
individual  statement  for  each  fund you own that  reflects  all  year-to-date
activity in your account.  You may request a statement of your account  activity
at any time.

    With the  exception of most  automatic  transactions,  each time you invest,
redeem,  transfer or exchange  shares,  we will send you a  confirmation  of the
transactions. See the Investor Services Guide for more detail.

    Carefully  review  all the  information  relating  to  transactions  on your
statements  and  confirmations  to ensure that your  instructions  were acted on
properly.  Please notify us immediately in writing if there is an error.  If you
fail to provide  notification  of an error  with  reasonable  promptness,  i.e.,
within 30 days of  non-automatic  transactions  or within 30 days of the date of
your consolidated quarterly statement, in the case of automatic transactions, we
will deem you to have ratified the transaction.

    No later than January  31st of each year,  we will send you reports that you
may use in completing  your U.S.  income tax return.  See the Investor  Services
Guide for more information.

    Each year,  we will send you an annual and a semiannual  report  relating to
your fund, each of which is incorporated herein by reference.  The annual report
includes audited financial  statements and a list of portfolio  securities as of
the  fiscal  year  end.  The  semiannual  report  includes  unaudited  financial
statements  for the first six  months of the fiscal  year,  as well as a list of
portfolio  securities at the end of the period. You also will receive an updated
prospectus at least once each year.  Please read these materials  carefully,  as
they will help you understand your Fund.

EMPLOYER-SPONSORED RETIREMENT PLANS AND INSTITUTIONAL ACCOUNTS

    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,  your  ability to  purchase  shares of the
funds, exchange them for shares of other American Century funds, and redeem them
will depend on the terms of your plan.

    If you  own or are  considering  purchasing  Fund  shares  through  a  bank,
broker-dealer,  insurance company or other financial intermediary,  your ability
to purchase,  exchange and redeem shares will depend on your agreement with, and
the policies of, such financial intermediary.

    You may reach one of our Institutional  Service  Representatives  by calling
1-800-345-3533 to request information about our funds and services,  to obtain a
current  prospectus or to get answers to any questions  about our funds that you
are unable to obtain through your plan administrator or financial intermediary.

                    ADDITIONAL INFORMATION YOU SHOULD KNOW

SHARE PRICE

WHEN SHARE PRICE IS DETERMINED

    The price of your shares is also  referred to as their net asset value.  Net
asset value is determined  by  calculating  the total value of a fund's  assets,
deducting  total  liabilities  and  dividing  the result by the number of shares
outstanding.  For all American  Century  funds,  except funds issued by American
Century Target  Maturities  Trust, net asset value is determined at the close of
regular trading on each day that the New York Stock Exchange is open,  usually 3
p.m.  Central time. Net asset values for Target  Maturities funds are determined
one hour prior to the close of the Exchange.

    Investments and requests to redeem or exchange shares will receive the share
price next  determined  after  receipt by us of the  investment,  redemption  or
exchange  request.  For example,  investments and requests to redeem or exchange
shares of a fund received by us or one of our agents before the time as of which
the net  asset  value of the fund is  determined,  are  effective  on,  and will
receive the price  determined,  that day.  Investment,  redemption  and exchange
requests received  thereafter are effective on, and receive the price determined
as of the close of the Exchange on, the next day the Exchange is open.

    Investments  are  considered  received  only when payment is received by us.
Wired funds are  considered  received on the day they are  deposited in our bank
account if they are deposited before the time as of which the net asset value is
determined.

    Investments by telephone pursuant to your prior  authorization to us to draw
on your bank account are considered received at the time of your telephone call.

    Investment and transaction  instructions  received by us on any business day
by mail  prior to the time as of which the net asset  value is  determined  will
receive that day's price.  Investments and instructions received after that time
will receive the price determined on the next business day.

    If you invest in Fund shares through an  employer-sponsored  retirement plan
or  other  financial  intermediary,  it  is  the  responsibility  of  your  plan
recordkeeper or financial  intermediary to transmit your purchase,  exchange and
redemption requests to the Fund's transfer agent prior to the applicable cut-off
time for receiving  orders and to make payment for any purchase  transactions in
accordance with the Fund's  procedures or any contractual  arrangement  with the
Fund or the Fund's distributor in order for you to receive that day's price.

HOW SHARE PRICE IS DETERMINED

    The valuation of assets for determining net asset value may be summarized as
follows:

    Portfolio  securities  of the Fund,  except as  otherwise  noted,  listed or
traded on a domestic  securities  exchange  are valued at the last sale price on
that  exchange.  Portfolio  securities  primarily  traded on foreign  securities
exchanges  are  generally  valued  at  the  preceding  closing  values  of  such
securities on the exchange where primarily traded. If no sale is reported, or if
local convention or regulation so provides, the mean of the latest bid and asked
prices is used.  Depending on local convention or regulation,  securities traded
over-the-counter  are priced at the mean of the latest bid and asked prices,  or
at the last sale  price.  When  market  quotations  are not  readily  available,
securities and other assets are valued at fair value as determined in accordance
with procedures adopted by the Board of Trustees.

    Debt  securities  not traded on a principal  securities  exchange are valued
through  valuations  obtained from a commercial  pricing  service or at the most
recent  mean of the bid and asked  prices  provided  by  investment  dealers  in
accordance with procedures established by the Board of Trustees.

WHERE TO FIND INFORMATION ABOUT SHARE PRICE

   
    The net asset  values of the  Investor  Class of the fund are  published  in
leading  newspapers  daily. The net asset value, as well as yield information on
the Fund and all other funds in the  American  Century  family of funds,  may be
obtained by calling us or by accessing our Web site at www.americancentury.com.
    


18   ADDITIONAL INFORMATION YOU SHOULD KNOW         AMERICAN CENTURY INVESTMENTS


DISTRIBUTIONS

    The Fund expects to declare and pay distributions from net investment income
quarterly, although it may elect not to do so in any given quarter. The Fund may
forego a dividend if, for example, net currency losses exceed investment income.
Distributions from net realized securities gains, if any, generally are declared
and paid once a year,  but the Fund may make  distributions  on a more  frequent
basis to comply with the distribution requirements of the Internal Revenue Code,
in all  events in a manner  consistent  with the  provisions  of the  Investment
Company Act.

    You will  begin to  participate  in the  distributions  the day  after  your
purchase is  effective.  See "When Share Price is  Determined,"  page 18. If you
redeem  shares,  you will receive the  distribution  declared for the day of the
redemption.  If all shares are redeemed, the distribution on the redeemed shares
will be included with your redemption proceeds.

   
    Distributions  from net realized  securities  gains,  if any,  generally are
declared  and paid once a year,  but the Fund may make  distributions  on a more
frequent  basis to comply with the  distribution  requirements  of the  Internal
Revenue Code, in all events in a manner  consistent  with the  provisions of the
Investment Company Act.
    

    Participants in employer-sponsored retirement or savings plans must reinvest
all  distributions.   For  shareholders   investing  through  taxable  accounts,
distributions  will be  reinvested  unless  you elect to  receive  them in cash.
Distributions of less than $10 generally will be reinvested.  Distributions made
shortly  after a  purchase  by check  or ACH may be held up to 15 days.  You may
elect to have distributions on shares held in Individual Retirement Accounts and
403(b)  plans  paid  in  cash  only  if you are at  least  59-1/2  years  old or
permanently and totally disabled. Distribution checks normally are mailed within
seven days after the record date. Please consult our Investor Services Guide for
further information regarding your distribution options.

    A  distribution  of shares of the Fund does not  increase  the value of your
shares of your total return. At any given time the value of your shares includes
the  undistributed  net  gains,  if any,  realized  by the  Fund on the  sale of
portfolio securities,  and undistributed  dividends and interest received,  less
fund expenses.

    Because  undistributed gains and dividends are included in the value of your
shares prior to distribution, when they are distributed the value of your shares
will be  reduced  by the  amount  of the  distribution.  If you buy your  shares
through a taxable  account just before the  distribution,  you will pay the full
price for your shares,  and then receive a portion of the purchase price back as
a taxable distribution. See "Taxes," this page.

TAXES

    The Fund has elected to be taxed under  Subchapter M of the Internal Revenue
Code,  which means that to the extent its income is distributed to shareholders,
it pays no income taxes.

TAX-DEFERRED ACCOUNTS

    If Fund  shares  are  purchased  through  tax-deferred  accounts,  such as a
qualified  employer-sponsored  retirement  or savings  plan,  income and capital
gains  distributions  paid by the Fund will  generally not be subject to current
taxation,  but will  accumulate in your account under the plan on a tax-deferred
basis.

    Employer-sponsored  retirement and savings plans are governed by complex tax
rules.  If you elect to participate in your employer's  plan,  consult your plan
administrator,  your plan's  summary plan  description,  or a  professional  tax
advisor   regarding  the  tax   consequences  of   participation  in  the  plan,
contributions to, and withdrawals or distributions from the plan.

TAXABLE ACCOUNTS

    If Fund shares are purchased through taxable accounts,  distributions of net
investment  income  and net  short-term  capital  gains  are  taxable  to you as
ordinary income, except as described below. The dividends from net income of the
Fund do not qualify for the 70%  dividends-received  deduction for  corporations
since they are derived from interest  income.  Distributions  from net long-term
capital gains are taxable as long-term capital gains regardless of the length of
time you have held the shares on which such distributions are paid. However, you
should note that any loss  realized  upon the sale or  redemption of shares held
for six months or less will be treated as a long-term capital loss to the extent
of any  distribution  of  long-term  capital  gain to you with  respect  to such
shares.


PROSPECTUS                           ADDITIONAL INFORMATION YOU SHOULD KNOW   19


    Distributions  are taxable to you  regardless  of whether  they are taken in
cash or reinvested,  even if the value of your shares is below your cost. If you
purchase shares shortly before a capital gain distribution,  you must pay income
taxes on the  distribution,  even though the value of your investment (plus cash
received, if any) will not have increased.  In addition,  the share price at the
time you purchase shares may include  unrealized gains in the securities held in
the  investment  portfolio  of the  Fund.  If  these  portfolio  securities  are
subsequently  sold and the gains are  realized,  they  will,  to the  extent not
offset by capital losses,  be paid to you as a distribution of capital gains and
will be taxable to you as short-term or long-term capital gains.

    In January of the year  following the  distribution,  if you own shares in a
taxable account, you will receive a Form 1099-DIV notifying you of the status of
your distributions for federal income tax purposes.

    Distributions may also be subject to state and local taxes, even if all or a
substantial  part  of  such  distribution  are  derived  from  interest  on U.S.
government  obligations  which,  if you received them directly,  would be exempt
from state income tax. However, most but not all states allow this tax exemption
to pass through to Fund  shareholders  when the Fund pays  distributions  to its
shareholders.  You should  consult your tax advisor about the tax status of such
distributions in your own state.

    If you have not complied  with certain  provisions  of the Internal  Revenue
Code,  we are  required by federal  law to withhold  and remit to the IRS 31% of
reportable  payments (which may include dividends,  capital gains  distributions
and  redemptions).  Those  regulations  require  you to certify  that the Social
Security number or tax identification number you provide is correct and that you
are not subject to 31% withholding for previous  under-reporting to the IRS. You
will be  asked  to  make  the  appropriate  certification  on your  application.
Payments   reported  by  us  that  omit  your  Social  Security  number  or  tax
identification number will subject us to a penalty of $50, which will be charged
against  your account if you fail to provide the  certification  by the time the
report is filed, and is not refundable.

    Redemption of shares of the Fund (including  redemptions made in an exchange
transaction)  will be a taxable  transaction for federal income tax purposes and
shareholders  will generally  recognize a gain or loss in an amount equal to the
difference  between  the basis of the shares and the amount  received.  Assuming
that  shareholders hold such shares as a capital asset, the gain or loss will be
a capital gain or loss and will generally be long term if shareholders have held
such  shares for a period of more than one year.  If a loss is  realized  on the
redemption of Fund shares,  the reinvestment in additional Fund shares within 30
days before or after the  redemption  may be subject to the "wash sale" rules of
the Internal  Revenue Code,  resulting in a postponement  of the  recognition of
such loss for federal income tax purposes.

    The portfolio  manager  members of the teams  managing the Fund described in
this  Prospectus and their work experience for the last five years are listed as
follows:

    DOMINIC PEGLER,  Vice President,  is a fixed income  Portfolio  Manager.  He
Joined JPMIM London in 1996 after seven years at the Bank of England, serving as
an  economist  and in the  Reserves  Management  Department,  managing  the UK's
foreign  exchange  reserves.  His time at the Bank included a two-year term with
the Directorate of Monetary  Affairs.  Mr. Pegler holds a Bachelor's  degree and
Master's degree in Economics from the London School of Economics.

   
    DAVID SCHROEDER, Vice President, oversees JPMIM's management of the Fund and
has done so since  June 1997.  Mr.  Schroeder  is also of the teams that  manage
American    Century-Benham    Inflation-Adjusted    Treasury   Fund,    American
Century-Benham  Intermediate-Term  Treasury  Fund,  and the  series of  American
Century Target  Maturities  Trust. Mr. Schroeder joined the Manager in 1990 as a
Portfolio  Manager and serves as the group  leader of the  portfolio  management
teams which manage American  Century's U.S.  government and  international  bond
funds.
    

    For subadvisory services, the Manager pays JPMIM a monthly fee at the annual
rate of 0.20% of  average  daily  net  assets  up to $200  million  and 0.15% of
average  daily net assets in excess of $200  million.  For the fiscal year ended
December 31, 1996, the Manager paid JPMIM subadvisory fees equal to 0.19% of the
Fund's average daily net assets.

   
    The  activities  of the Manager are subject only to directions of the Fund's
Board of  Trustees.  The  Manager  pays  all the  expenses  of the  Fund  except
brokerage,  taxes,  portfolio  insurance,  interest,  fees and  expenses  of the
non-interested  person  Trustees  (including  counsel  fees)  and  extraordinary
expenses.

    For the services  provided to the Fund,  the Manager  receives a monthly fee
based on a percentage of the average net assets of the Fund.  The annual rate at
which this fee is assessed is determined monthly in a two-step process: First, a
fee rate  schedule is applied to the assets of all of the bond funds  managed by
the  Manager  (the  "Investment  Category  Fee").  Second,  a separate  fee rate
schedule  is applied to the  assets of all of the funds  managed by the  Manager
(the "Complex  Fee").  The Investment  Category Fee and the Complex Fee are then
added  to  determine  the  unified  management  fee  payable  by the Fund to the
Manager.  Currently,  the Investment Category Fee for the Fund is an annual rate
of 0.54% of the average net assets of the Fund.  The Complex Fee is currently an
annual rate of 0.30% of the average net assets of the Fund. Further  information
about the calculation of the annual management fee is contained in the Statement
of Additional Information.

    On the first  business day of each month,  the Fund pays a management fee to
the  Manager  for the  previous  month at the  specified  rate.  The fee for the
previous month is calculated by  multiplying  the applicable fee for the Fund by
the  aggregate  average  daily closing value of the Fund's net assets during the
previous  month by a fraction,  the  numerator of which is the number of days in
the previous month and the denominator of which is 365 (366 in leap years).
    

CODE OF ETHICS

    The Trust and the  Manager  have  adopted a Code of Ethics  which  restricts
personal  investing  practices by  employees of the Manager and its  affiliates.
Among other  provisions,  the Code of Ethics requires that employees with access
to information about the purchase or sale of securities in the Fund's portfolios
obtain  preclearance before executing personal trades. With respect to Portfolio
Managers  and  other  investment   personnel,   the  Code  of  Ethics  prohibits
acquisition  of securities  in an initial  public  offering,  as well as profits
derived from the purchase and sale of the same security within 60 calendar days.
These  provisions  are  designed  to  ensure  that  the  interests  of the  Fund
shareholders come before the interests of the people who manage the Fund.

TRANSFER AND ADMINISTRATIVE SERVICES

   
    American  Century  Services  Corporation,  4500 Main  Street,  Kansas  City,
Missouri 64111, acts as transfer agent and  dividend-paying  agent for the Fund.
It provides facilities, equipment and personnel to the Fund and is paid for such
services by the Manager.
    

    The Fund  charges no sales  commissions,  or "loads," of any kind.  However,
investors who do not choose to purchase or sell Fund shares directly from


PROSPECTUS                           ADDITIONAL INFORMATION YOU SHOULD KNOW   21


the  transfer  agent  may  purchase  or  sell  Fund  shares  through  registered
broker-dealers and other qualified service  providers,  who may charge investors
fees for their services.  These  broker-dealers and service providers  generally
provide  shareholder,  administrative  and/or  accounting  services  which would
otherwise be provided by the transfer agent. To accommodate these investors, the
Manager and its affiliates have entered into agreements with some broker-dealers
and service  providers to provide  these  services.  Fees for such  services are
borne  normally by the Fund at the rates  normally  paid to the transfer  agent,
which would otherwise provide the services. Any distribution expenses associated
with these arrangements are borne by the Manager.

    From time to time,  special  services  may be  offered to  shareholders  who
maintain  higher  share  balances  in our family of funds.  These  services  may
include the waiver of minimum investment requirements, expedited confirmation of
shareholder  transactions,  newsletters and a team of personal  representatives.
Any expenses  associated with these special services will be paid by the Manager
or its affiliates.

    The Manager and the transfer  agent are both wholly  owned by ACC.  James E.
Stowers Jr.,  Chairman of the Board of Directors of ACC,  controls ACC by virtue
of his ownership of a majority of its common stock.

DISTRIBUTION OF FUND SHARES

   
    The Fund's shares are distributed by American Century  Investment  Services,
Inc. (the  "Distributor"),  a registered  broker-dealer  and an affiliate of the
Manager.  The Manager (or an affiliate) pays all expenses  incurred in promoting
and  distributing  the Investor Class of Fund shares offered by this Prospectus.
The Investor  Class of shares does not pay any  commissions or other fees to the
distributor  or to any  other  broker-dealers  or  financial  intermediaries  in
connection with the distribution of Fund shares.
    

FURTHER INFORMATION ABOUT AMERICAN CENTURY

    The Fund is an open-end  management  investment  company.  Its  business and
affairs  are  managed  by its  officers  under  the  direction  of its  Board of
Trustees.

    The  principal  office of the Trust is  American  Century  Tower,  4500 Main
Street, P.O. Box 419200, Kansas City, Missouri 64141-6200.  All inquiries may be
made by mail to that address,  or by telephone to 1-800-345-2021  (international
calls: 816-531-5575).

    The Fund is an  individual  series of the Trust which issues  shares with no
par value. Each series is commonly referred to as a fund. Currently, the Fund is
the only existing series of the Trust.  In the event that  additional  series of
the Trust are  created,  the assets  belonging to each series of shares are held
separately by the custodian and in effect each series is a separate fund.

   
    American  Century  International  Bond Funds  offers two classes of the Fund
offered by this  Prospectus:  an Investor Class and an Advisor Class. The shares
offered by this  Prospectus  are  Investor  Class  shares  and have no  up-front
charges, commissions or 12b-1 fees.

    The Advisor Class of shares is primarily offered to institutional  investors
or through  institutional  distributions  channels,  such as  employer-sponsored
retirement plans or through banks, broker-dealers,  insurance companies or other
financial intermediaries.  This other class has different fees, expenses, and/or
minimum  investment  requirements than the Investor Class. The difference in the
fee structures  among the classes is the result of their  separate  arrangements
for shareholder and  distribution  services and not the result of any difference
in  amounts  charged  by the  Manager  for core  investment  advisory  services.
Accordingly,  the  core  investment  advisory  expenses  do not  vary by  class.
Different fees and expenses will affect performance.  For additional information
concerning the Advisor Class of shares not offered by this Prospectus,  call one
of our Investor Services Representatives at 1-800-345-2021.

    Except as described  below,  all classes of shares of a Fund have  identical
voting,  dividend,   liquidation  and  other  rights,  preferences,   terms  and
conditions.  The only  differences  among the various classes are (a) each class
may be subject to different  expenses specific to that class, (b) each class has
a different identifying designation or name, (c) each class has exclusive voting
rights with respect to matters solely  affecting such class,  and (d) each class
may have different exchange privileges.
    

    Each  share,  irrespective  of series or class,  is entitled to one vote for
each dollar of net asset value applicable to such share on all questions, except
for


22   ADDITIONAL INFORMATION YOU SHOULD KNOW         AMERICAN CENTURY INVESTMENTS


those matters which must be voted on separately by the series or class of shares
affected. Matters affecting only one series or class are voted upon only by that
series or class.

    Shares have  non-cumulative  voting rights,  which means that the holders of
more than 50% of the votes cast in an election of Trustees  can elect all of the
Trustees if they choose to do so, and in such event the holders of the remaining
votes will not be able to elect any person or persons to the Board of Trustees.

    Unless required by the Investment  Company Act, it will not be necessary for
the Trust to hold annual meetings of shareholders. As a result, shareholders may
not vote each year on the election of Trustees or the  appointment  of auditors.
However,  pursuant to the Trust's by-laws, the holders of shares representing at
least 10% of the votes  entitled  to be cast may  request  that the Trust hold a
special meeting of shareholders. The Trust will assist in the communication with
other shareholders.

    WE RESERVE THE RIGHT TO CHANGE ANY OF OUR POLICIES, PRACTICES AND PROCEDURES
DESCRIBED IN THIS PROSPECTUS, INCLUDING THE STATEMENT OF ADDITIONAL INFORMATION,
WITHOUT  SHAREHOLDER  APPROVAL  EXCEPT  IN  THOSE  INSTANCES  WHERE  SHAREHOLDER
APPROVAL IS EXPRESSLY REQUIRED.

    THIS PROSPECTUS  CONSTITUTES AN OFFER TO SELL SECURITIES OF THE FUND ONLY IN
THOSE STATES WHERE THE FUND'S SHARES HAVE BEEN REGISTERED OR OTHERWISE QUALIFIED
FOR SALE. THE FUND WILL NOT ACCEPT  APPLICATIONS FROM PERSONS RESIDING IN STATES
WHERE THE FUND'S SHARES ARE NOT REGISTERED.

AMERICAN CENTURY -- BENHAM INTERNATIONAL BOND FUND

investing in high-quality,  nondollar-denominated  government and corporate debt
securities  outside the United  States.  Prior to October 1, 1997,  the Fund was
known as  "American  Century-  Benham  European  Government  Bond  Fund" and its
investment  objective  was "to seek  over the long term as high a level of total
return  as  is  consistent  with  investment  in  the  highest-quality  European
government debt securities."

NO  PERSON  IS  AUTHORIZED  BY THE  FUND TO GIVE  ANY  INFORMATION  OR MAKE  ANY
REPRESENTATION OTHER THAN THOSE CONTAINED IN THIS PROSPECTUS OR IN OTHER PRINTED

(1) A portion of the management fee may be paid by American  Century  Investment
    Management,  Inc. (the "Manager") to unaffiliated  third parties who provide
    recordkeeping and administrative  services that would otherwise be performed
    by  an   affiliate  of  the  Manager.   See   "Management   -  Transfer  and
    Administrative Services," page 16.

(2) The 12b-1 fee is designed to permit  investors  to  purchase  Advisor  Class
    shares  through   broker-dealers,   banks,  insurance  companies  and  other
    financial  intermediaries.  A portion of the fee is used to compensate  them
    for ongoing  recordkeeping and administrative  services that would otherwise
    be  performed  by an  affiliate  of the  Manager,  and a portion  is used to
    compensate  them  for  distribution  and  other  shareholder  services.  See
    "Service and Distribution Fees," page 17.

  The purpose of the above table is to help you understand the various costs and
expenses  that you,  as a  shareholder,  will bear  directly  or  indirectly  in
connection  with an  investment  in the class of shares of the American  Century
Fund  offered  by  this   Prospectus.   The  example  set  forth  above  assumes
reinvestment  of all  dividends and  distributions  and uses a 5% annual rate of
return as required by SEC regulations.

  NEITHER  THE 5%  RATE OF  RETURN  NOR  THE  EXPENSES  SHOWN  ABOVE  SHOULD  BE
CONSIDERED  INDICATIONS OF PAST OR FUTURE  RETURNS AND EXPENSES.  ACTUAL RETURNS
AND EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

  The shares  offered by this  Prospectus  are Advisor  Class  shares.  The Fund
offers one other  class of shares,  primarily  to retail  investors,  that has a
different  fee  structure  than the Advisor  Class.  The  difference  in the fee
structures  among the classes is the result of their separate  arrangements  for
shareholder  and  distribution  services and not the result of any difference in
amounts  charged  by  the  Manager  for  core  investment   advisory   services.
Accordingly,  the core  investment  advisory  expenses  do not vary by class.  A
difference in fees will result in different  performance for those classes.  For
additional information about the various classes, see "Further Information About
American Century," page 17.

                              INTERNATIONAL BOND

  The Advisor Class of the Fund was established October 1, 1997;  therefore,  no
shares had been issued prior to the Fund's prior fiscal year end. The  financial
information  in this  table  regarding  selected  per  share  data  for the Fund
reflects the  performance of the Fund's  Investor  Class of shares,  which has a
total expense ratio that is 0.25% lower than the Advisor Class.  Had the Advisor

PROSPECTUS                  PERFORMANCE INFORMATION OF OTHER CLASS     5


                        INFORMATION REGARDING THE FUND

INVESTMENT POLICIES OF THE FUND

    The Fund has adopted certain  investment  restrictions that are set forth in
the  Statement of Additional  Information.  Those  restrictions,  as well as the
investment objective of the Fund identified on page 2 of this Prospectus and any
other investment  policies  designated as "fundamental" in this Prospectus or in
the Statement of Additional  Information,  cannot be changed without shareholder
approval.  The Fund has implemented additional investment policies and practices
to guide its  activities  in the  pursuit  of its  investment  objective.  These
policies and practices,  which are described throughout this Prospectus, are not
designated  as  fundamental  policies  and may be  changed  without  shareholder
approval.

    For an explanation of the  securities  ratings  referred to in the following
discussion, see "Other Information" in the Statement of Additional Information.

INVESTMENT OBJECTIVE

    The Fund seeks to provide high current  income and capital  appreciation  by
investing in high-quality,  nondollar-denominated  government and corporate debt
securities  outside the United States.  There is no assurance that the Fund will
achieve its investment  objective.  The Fund is a  "non-diversified  company" as
defined in the Investment  Company Act of 1940 (the  "Investment  Company Act"),
which means that the proportion of the Fund's assets that may be invested in the
securities of a single issuer is not limited by the Investment Company Act.

    The Fund may be appropriate for U.S. investors who:

    *    Want to protect their income against a decline in the purchasing power
         of the U.S. dollar  relative to that of foreign currencies.

    *    Want to diversify their investments beyond U.S. dollar-denominated
         securities and interest rate exposure.

    As market conditions change (i.e.,  interest rate,  political,  and economic
changes  occur),  the Fund's  value will vary.  The Fund's  performance  will be
affected by currency values,  foreign  economies,  and other foreign  investment
factors.

INTERNATIONAL SUBADVISOR

    J.P. Morgan  Investment  Management Inc.  ("JPMIM") is the Fund's subadvisor
and is responsible for its day-to-day operations.  JPMIM is headquartered in New
York and maintains offices in most of the world's financial  centers,  including
London and Frankfurt.

INVESTMENT STRATEGY

    JPMIM selects the Fund's  investments  by using a combination of fundamental
research  and bond and  currency  valuation  models.  The  following  is a brief
summary of factors considered by JPMIM in selecting the Fund's investments:

    *    ECONOMIC/POLITICAL FUNDAMENTALS: JPMIM evaluates each country's
         economic climate and political discipline for controlling deficits and
         inflation.

    *    EXPECTED RETURN: Using economic forecasts, JPMIM projects the expected
         return for each country.

    *    RELATIVE VALUE: By contrasting expected risks and returns for
         investments in each country, JPMIM selects those countries expected to
         produce the best return at reasonable risk.

    The Fund's  investments  may  include  but shall not be limited to: (1) Debt
obligations issued or guaranteed by (a) a foreign sovereign government or one of
its agencies, authorities, instrumentalities or political subdivisions including
a foreign state, province or municipality,  and (b) supranational  organizations
such as the World Bank, Asian  Development Bank,  European  Investment Bank, and
European Economic Community;  (2) Debt obligations of (a) foreign banks and bank
holding  companies,  and (b) domestic banks and  corporations  issued in foreign
currencies;  and (3) Foreign corporate debt securities and commercial paper. All
of these  investments must satisfy the credit quality  standards (i.e.,  "AA" or
higher) established by the Trustees of the Fund.


6     INFORMATION REGARDING THE FUND           AMERICAN CENTURY INVESTMENTS


    Such  securities may take a variety of forms  including  those issued in the
local currency of the issuer,  Euro bonds, and bonds denominated in the European
currencies or ECUs. ECUs are a composite currency consisting of fixed amounts of
currency of European  Economic  Community member countries.  Normally,  the Fund
will only purchase bonds denominated in foreign currencies.

PORTFOLIO COMPOSITION

    Under  normal  market  conditions,  the Fund will invest at least 65% of its
total  assets in bonds  issued or  guaranteed  by foreign  governments  or their
agencies and by foreign authorities,  provinces and municipalities. The Fund may
invest  up to 35% of its total  assets  in  high-quality  (i.e.,  rated  "AA" or
higher) foreign corporate debt securities.

    The Fund's credit quality  requirements  effectively  limit the countries in
which the Fund may invest.  As of the date of this Prospectus,  the Fund expects
to invest  in the  securities  of  issuers  located  in and  governments  of the
following countries:  Australia,  Austria,  Belgium,  Canada, Denmark,  Finland,
France, Germany, Ireland, Japan, Liechtenstein, Luxembourg, Netherlands, Norway,
Portugal, Singapore, Spain, Sweden, Switzerland,  Taiwan, and United Kingdom. To
limit the  possibility  that the Fund will become unduly  concentrated in Japan,
the Fund currently  limits its investment in issuers located in Japan to no more
than 15% of total assets.

CURRENCY MANAGEMENT

    The rate of exchange between U.S. dollars and foreign currencies fluctuates,
which  results  in gains  and  losses to the Fund.  Even if the  Fund's  foreign
security  holdings perform well, an increase in the value of the dollar relative
to the currencies in which  portfolio  securities are denominated can offset net
investment income.

    Because  the  Fund is  designed  for U.S.  investors  seeking  currency  and
interest  rate  diversification,  JPMIM  limits  its use of  hedging  strategies
intended  to  minimize  the effect of currency  fluctuations.  Although  hedging
strategies (if they are successful)  reduce exchange rate risk, they also reduce
the potential for share price appreciation when foreign  currencies  increase in
value relative to the U.S. dollar.

    When JPMIM  considers the U.S.  dollar to be attractive  relative to foreign
currencies,  as  much as 25% of the  Fund's  total  assets  may be  hedged  into
dollars. For temporary defensive purposes and under extraordinary  circumstances
(such as significant political events), more than 25% of the Fund's total assets
may be hedged in this manner.

    In managing the Fund's  currency  exposure,  JPMIM will buy and sell foreign
currencies  regularly,  either in the spot  (i.e.,  cash)  market or the forward
market.  Forward foreign currency exchange contracts  ("forward  contracts") are
individually  negotiated and privately  traded between currency traders (usually
large  commercial  banks)  and  their  customers.  In  most  cases,  no  deposit
requirements  exist,  and these  contracts  are  traded  at a net price  without
commission.  Forward  contracts  involve an  obligation  to  purchase  or sell a
specific  currency at an  agreed-upon  price on a future  date.  Most  contracts
expire in less than one year.  The Fund may also use  futures  and  options  for
currency  management  purposes.  The Fund will not use  futures  and options for
speculative  purposes.  For more information on futures and options,  please see
"Interest Rate Futures Contracts and Options Thereon" on page 9.

RISK FACTORS

INVESTING IN FOREIGN SECURITIES

    Investing in securities of foreign issuers generally  involves greater risks
than investing in the securities of domestic  companies.  As with any investment
in  securities,  the value of an  investment in the Fund can decrease as well as
increase,  depending  upon a variety of factors  which may affect the values and
income  generated by the Fund's  portfolio  securities.  Investments in the Fund
should  not  be  considered  a  complete  investment  program  and  may  not  be
appropriate for an individual with limited investment resources or who is unable
to tolerate  fluctuations  in the value of the investment.  Potential  investors
should carefully consider the following factors:

    Currency Risk. The value of the foreign  investments held by the Fund may be
significantly  affected by changes in currency  exchange rates. The dollar value
of a foreign  security  generally  decreases  when the value of the dollar rises
against the foreign cur-


PROSPECTUS                          INFORMATION REGARDING THE FUND       7


rency in which the security is denominated  and tends to increase when the value
of the dollar falls against such currency. In addition, the value of Fund assets
may be affected by losses and other  expenses  incurred  in  converting  between
various  currencies  in order to purchase  and sell  foreign  securities  and by
currency  restrictions,  exchange control regulation,  currency devaluations and
political developments.

    Political and Economic Risk. The economies of many of the countries in which
the Fund invests are not as  developed  as the economy of the United  States and
may  be  subject  to  significantly   different  forces.   Political  or  social
instability,  expropriation,  nationalization,  or  confiscatory  taxation,  and
limitations on the removal of funds or other assets, could also adversely affect
the value of  investments.  Further,  the Fund may encounter  difficulties or be
unable to pursue legal remedies or obtain judgments in foreign courts.

    Regulatory  Risk.  Foreign  companies  are  generally  not  subject  to  the
regulatory  controls  imposed on U.S.  issuers  and, in  general,  there is less
publicly available  information about foreign securities than is available about
domestic  securities.   Many  foreign  companies  are  not  subject  to  uniform
accounting,   auditing  and  financial   reporting   standards,   practices  and
requirements  comparable to those applicable to domestic companies.  Income from
foreign  securities owned by the Fund may be reduced by a withholding tax at the
source which would reduce dividend income payable to shareholders.  See "Taxes,"
page 14.

    Market and Trading Risk.  Brokerage  commission rates in foreign  countries,
which are generally  fixed rather than subject to  negotiation  as in the United
States, are likely to be higher. The securities markets in many of the countries
in which the Fund invest will have  substantially  less trading  volume than the
principal U.S. markets.  As a result,  the securities of some companies in these
countries may be less liquid and more volatile than comparable U.S.  securities.
Furthermore,  one securities  broker may represent all or a significant  part of
the trading  volume in a particular  country,  resulting in higher trading costs
and decreased liquidity due to a lack of alternative trading partners.  There is
generally less government regulation and supervision of foreign stock exchanges,
brokers  and  issuers  which  may  make  it  difficult  to  enforce  contractual
obligations.

    Clearance  and  Settlement  Risk.   Foreign  securities  markets  also  have
different clearance and settlement procedures, and in certain markets there have
been times  when  settlements  have been  unable to keep pace with the volume of
securities  transactions,  making it  difficult  to conduct  such  transactions.
Delays in clearance and settlement could result in temporary periods when assets
of the Fund are uninvested and no return is earned thereon. The inability of the
Fund to  make  intended  security  purchases  due to  clearance  and  settlement
problems  could  cause  the Fund to miss  attractive  investment  opportunities.
Inability to dispose of portfolio  securities  due to clearance  and  settlement
problems could result either in losses to the Fund due to subsequent declines in
value of the  portfolio  security or, if the Fund has entered into a contract to
sell the security, liability to the purchaser.

CREDIT QUALITY

    Under normal  circumstances,  the Fund invests  exclusively in securities of
issuers rated high quality,  nondollar-denominated government and corporate debt
securities  outside the United  States.  "High  quality" means that the security
must be rated AA or higher, at the time of purchase,  by a nationally recognized
statistical rating agency or considered by JPMIM to be of comparable quality. If
a rating  agency  downgrades a security held by the Fund or judges a security to
be less than AA  quality,  the  security  would be sold as quickly  as  possible
without unnecessarily destabilizing the Fund's share price or yield.

DOLLAR-WEIGHTED AVERAGE MATURITY

    The Fund's dollar-weighted average portfolio maturity ranges from two to ten
years.

OTHER INVESTMENT PRACTICES, THEIR CHARACTERISTICS AND RISKS

    For additional  information  regarding the investment practices of the Fund,
see the Statement of Additional Information.

PORTFOLIO TURNOVER

    The  portfolio  turnover  rates  of the Fund  are  shown in the  Performance
Information of Other Class table on page 5 of this Prospectus.

    Investment  decisions  to  purchase  and sell  securities  are  based on the
anticipated contribution of the secu-


8     INFORMATION REGARDING THE FUND             AMERICAN CENTURY INVESTMENTS


rity in question to the Fund's objectives. The Manager believes that the rate of
portfolio  turnover is  irrelevant  when it or JPMIM  determines  a change is in
order to  achieve  those  objectives  and,  accordingly,  the  annual  portfolio
turnover rate cannot be accurately predicted.

    The  portfolio  turnover of the Fund may be higher than other  mutual  funds
with   similar   investment   objectives.   Higher   turnover   would   generate
correspondingly  greater  brokerage  commissions,  which is a cost that the Fund
pays  directly.  Portfolio  turnover  may also affect the  character  of capital
gains,  if any,  realized and distributed by the Fund since  short-term  capital
gains are taxable as ordinary income.

    Transaction  costs are normally higher for foreign  securities than for U.S.
securities; therefore, the Fund's anticipated portfolio turnover rate may have a
larger  negative  impact  on total  return  than it  would if the Fund  invested
primarily or exclusively in U.S. securities.

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

    The Fund may sometimes purchase new issues of securities on a when-issued or
forward  commitment  basis when, in the opinion of the Manager,  such  purchases
will  further the  investment  objective of the Fund.  The price of  when-issued
securities  is  established  at the time the  commitment  to  purchase  is made.
Delivery  of and  payment for these  securities  typically  occurs 15 to 45 days
after the commitment to purchase. Market rates of interest on debt securities at
the time of  delivery  may be higher or lower than those  contracted  for on the
security.  Accordingly, the value of the security may decline prior to delivery,
which could result in a loss to the Fund.

INTEREST RATE FUTURES CONTRACTS AND OPTIONS THEREON

    The Fund may buy or sell  interest rate futures  contracts  relating to debt
securities ("debt futures," i.e., futures relating to indexes on types or groups
of bonds)  and  write or buy put and call  options  relating  to  interest  rate
futures contracts.

    For options sold, the Fund will segregate cash or appropriate  liquid assets
including equity  securities and debt securities of any grade equal to the value
of securities underlying the option unless the option is otherwise covered.

    The Fund will  deposit  cash or  appropriate  liquid  assets in a segregated
custodial  account in an amount  equal to the  fluctuating  market value of long
futures  contracts  it has  purchased,  less any  margin  deposited  on its long
position.  It may hold cash or acquire such debt  obligations for the purpose of
making these deposits.

    The Fund may use futures and options  transactions to maintain cash reserves
while remaining fully invested,  to facilitate  trading,  to reduce  transaction
costs, or to pursue higher investment  returns when a futures contract is priced
more attractively than its underlying security or index.

    Since futures  contracts and options thereon can replicate  movements in the
markets  for the  securities  in which the Fund  invests  without the large cash
investments  required for dealing in such markets,  they may subject the Fund to
greater and more volatile risks than might  otherwise be the case. The principal
risks related to the use of such instruments are (1) the offsetting  correlation
between  movements in the market  price of the  portfolio  investments  (held or
intended) being hedged and in the price of the futures contract or option may be
imperfect;  (2)  possible  lack of a liquid  secondary  market for  closing  out
futures or option  positions;  (3) the need of additional  portfolio  management
skills  and  techniques;  and  (4)  losses  due to  unanticipated  market  price
movements.  For a hedge to be  completely  effective,  the  price  change of the
hedging instrument should equal the price change of the securities being hedged.
Such  equal  price  changes  are not  always  possible  because  the  investment
underlying the hedging  instrument may not be the same  investment that is being
hedged.

    The ordinary spreads between prices in the cash and futures markets,  due to
the differences in the nature of those markets,  are subject to distortion.  Due
to the possibility of distortion,  a correct  forecast of general  interest rate
trends by the  Manager  may still not result in a  successful  transaction.  The
Manager  may be  incorrect  in its  expectations  as to the  extent  of  various
interest rate movements or the time span within which the movements take place.

    See the Statement of Additional  Information for further  information  about
these instruments and their risks.


PROSPECTUS                         INFORMATION REGARDING THE FUND       9


SHORT-TERM INSTRUMENTS

    For liquidity  purposes,  the Fund may invest in  high-quality  money market
instruments with remaining  maturities of one year or less. Such instruments may
include  nondollar-denominated   obligations  of  foreign  governments,  foreign
government agencies,  and supranational  organizations,  as well as high-quality
certificates of deposit.

    The Fund may also enter into repurchase  agreements,  collateralized by U.S.
government  securities,  with banks or broker-dealers that are deemed to present
minimal credit risk. Credit risk determinations are made by the Manager pursuant
to  guidelines  established  by the Board of Trustees.  A  repurchase  agreement
involves  the purchase of a security  and a  simultaneous  agreement to sell the
security back to the seller at a higher price.  Delays or losses could result if
the other party to the agreement defaults or becomes bankrupt.

    The Fund may invest up to 5% of its total  assets in any money  market  fund
advised by the Manager,  provided that the  investment  is  consistent  with the
Fund's investment policies and restrictions.

SECURITIES LENDING

    In order  to  realize  additional  income,  the Fund may lend its  portfolio
securities  to  persons  not  affiliated  with  it  and  who  are  deemed  to be
creditworthy.  Such  loans  must be  secured  continuously  by  cash  collateral
maintained on a current basis in an amount at least equal to the market value of
the securities loaned, or by irrevocable letters of credit. During the existence
of the loan,  the Fund must  continue to receive the  equivalent of the interest
and dividends  paid by the issuer on the  securities  loaned and interest on the
investment of the collateral.  The Fund must have the right to call the loan and
obtain the  securities  loaned at any time on five days'  notice,  including the
right to call the loan to enable the Fund to vote the securities.  This practice
could result in a loss or a delay in recovering the Fund's securities.

    The Fund may not lend any  security  or make any other loan if, as a result,
more than 33-1/3% of the Fund's  total assets would be lent to other  parties in
the manner described above.

OTHER TECHNIQUES

    JPMIM may buy other types of securities or employ other portfolio management
techniques on behalf of the Fund.  When SEC guidelines  require it to do so, the
Fund will set aside cash or appropriate liquid assets in a segregated account to
cover its  obligations.  See the Statement of Additional  Information for a more
detailed  discussion of these  investments and some of the risks associated with
them.

PERFORMANCE ADVERTISING

    From time to time, the Fund may advertise performance data. Fund performance
may be shown  by  presenting  one or more  performance  measurements,  including
cumulative  total return or average  annual total  return,  yield and  effective
yield.  Performance data may be quoted  separately for the Advisor Class and for
the other class offered by the Fund.

    Cumulative  total  return data is computed by  considering  all  elements of
return,  including  reinvestment  of dividends and capital gains  distributions,
over a stated  period of time.  Average  annual  total return is  determined  by
computing  the annual  compound  return over a stated  period of time that would
have  produced  the Fund's  cumulative  total return over the same period if the
Fund's performance had remained constant throughout.

    A  quotation  of yield  reflects  the  Fund's  income  over a stated  period
expressed as a percentage  of the Fund's share  price.  The  effective  yield is
calculated in a similar manner,  but, when annualized,  the income earned by the
investment is assumed to be  reinvested.  The  effective  yield will be slightly
higher  than  the  yield  because  of the  compounding  effect  on  the  assumed
reinvestment.

    Yield is  calculated  by adding  over a 30-day  (or  one-month)  period  all
interest and dividend  income (net of fund  expenses)  calculated  on each day's
market  values,  dividing  this  sum  by  the  average  number  of  Fund  shares
outstanding  during the period, and expressing the result as a percentage of the
Fund's  share  price on the last day of the 30-day (or one  month)  period.  The
percentage is then annualized.  Capital gains and losses are not included in the
calculation.


10      INFORMATION REGARDING THE FUND         AMERICAN CENTURY INVESTMENTS


    Yields are calculated  according to accounting methods that are standardized
in accordance with SEC rules.  Because yield accounting  methods differ from the
methods  used for other  accounting  purposes,  a Fund's yield may not equal the
income  paid on its  shares  or the  income  reported  in the  Fund's  financial
statements.

    The Fund may also include in advertisements data comparing  performance with
the performance of non-related  investment media,  published  editorial comments
and performance  rankings compiled by independent  organizations (such as Lipper
Analytical  Services) and  publications  that monitor the  performance of mutual
funds.  Performance information may be quoted numerically or may be presented in
a table,  graph or other  illustration.  In addition,  Fund  performance  may be
compared to well-known indices of market performance.  Fund performance may also
be compared,  on a relative basis,  to the other funds in our fund family.  This
relative  comparison,  which  may be based  upon  historical  or  expected  fund
performance,  volatility  or  other  Fund  characteristics,   may  be  presented
numerically,  graphically or in text.  Fund  performance may also be combined or
blended  with  other  funds in our fund  family,  and that  combined  or blended
performance may be compared to the same indices to which individual funds may be
compared.

    All performance  information  advertised by the Fund is historical in nature

12 HOW TO INVEST WITH AMERICAN CENTURY INVESTMENTS  AMERICAN CENTURY INVESTMENTS


                    ADDITIONAL INFORMATION YOU SHOULD KNOW

SHARE PRICE

WHEN SHARE PRICE IS DETERMINED

    The price of your shares is also  referred to as their net asset value.  Net
asset value is determined  by  calculating  the total value of a fund's  assets,
deducting  total  liabilities  and  dividing  the result by the number of shares
outstanding.  For all American  Century  funds,  except funds issued by American
Century Target  Maturities  Trust, net asset value is determined at the close of
regular trading on each day that the New York Stock Exchange is open,  usually 3
p.m.  Central time. Net asset values for Target  Maturities funds are determined
one hour prior to the close of the Exchange.

    Investments and requests to redeem or exchange shares will receive the share
price next  determined  after  receipt by us of the  investment,  redemption  or
exchange  request.  For example,  investments and requests to redeem or exchange
shares of a fund received by us or one of our agents before the time as of which
the net  asset  value of the fund is  determined,  are  effective  on,  and will
receive the price  determined,  that day.  Investment,  redemption  and exchange
requests received  thereafter are effective on, and receive the price determined
as of the close of the Exchange on, the next day the Exchange is open.

    Investments  are  considered  received  only when payment is received by us.
Wired funds are  considered  received on the day they are  deposited in our bank
account if they are deposited before the time as of which the net asset value is
determined.

    Investments by telephone pursuant to your prior  authorization to us to draw
on your bank account are considered received at the time of your telephone call.

    Investment and transaction  instructions  received by us on any business day
by mail  prior to the time as of which the net asset  value is  determined  will
receive that day's price.  Investments and instructions received after that time
will receive the price determined on the next business day.

    If you invest in Fund shares through an  employer-sponsored  retirement plan
or  other  financial  intermediary,  it  is  the  responsibility  of  your  plan
recordkeeper or financial  intermediary to transmit your purchase,  exchange and
redemption requests to the Fund's transfer agent prior to the applicable cut-off
time for receiving  orders and to make payment for any purchase  transactions in
accordance with the Fund's  procedures or any contractual  arrangement  with the
Fund or the Fund's distributor in order for you to receive that day's price.

HOW SHARE PRICE IS DETERMINED

    The valuation of assets for determining net asset value may be summarized as
follows:

    Portfolio  securities  of the Fund,  except as  otherwise  noted,  listed or
traded on a domestic  securities  exchange  are valued at the last sale price on
that  exchange.  Portfolio  securities  primarily  traded on foreign  securities
exchanges  are  generally  valued  at  the  preceding  closing  values  of  such
securities on the exchange where primarily traded. If no sale is reported, or if
local convention or regulation so provides, the mean of the latest bid and asked
prices is used.  Depending on local convention or regulation,  securities traded
over-the-counter  are priced at the mean of the latest bid and asked prices,  or
at the last sale  price.  When  market  quotations  are not  readily  available,
securities and other assets are valued at fair value as determined in accordance
with procedures adopted by the Board of Trustees.

    Debt  securities  not traded on a principal  securities  exchange are valued
through  valuations  obtained from a commercial  pricing  service or at the most
recent  mean of the bid and asked  prices  provided  by  investment  dealers  in
accordance with procedures established by the Board of Trustees.

WHERE TO FIND INFORMATION ABOUT SHARE PRICE

    The net asset  values of the  Investor  Class of the fund are  published  in
leading newspapers daily.  Because the total expense ratio for the Advisor Class
shares is 0.25% higher than the Investor  Class,  their net asset values will be
lower than the Investor Class.  The net asset values of the Advisor Class may be
obtained by calling us.


PROSPECTUS                  ADDITIONAL INFORMATION YOU SHOULD KNOW       13


DISTRIBUTIONS

    The Fund expects to declare and pay distributions from net investment income
quarterly, although it may elect not to do so in any given quarter. The Fund may
forego a dividend if, for example, net currency losses exceed investment income.
Distributions from net realized securities gains, if any, generally are declared
and paid once a year,  but the Fund may make  distributions  on a more  frequent
basis to comply with the distribution requirements of the Internal Revenue Code,
in all  events in a manner  consistent  with the  provisions  of the  Investment
Company Act.

    You will  begin to  participate  in the  distributions  the day  after  your
purchase is  effective.  See "When Share Price is  Determined,"  page 13. If you
redeem  shares,  you will receive the  distribution  declared for the day of the
redemption.  If all shares are redeemed, the distribution on the redeemed shares
will be included with your redemption proceeds.

    Distributions  from net realized  securities  gains,  if any,  generally are
declared  and paid once a year,  but the Fund may make  distributions  on a more
frequent  basis to comply with the  distribution  requirements  of the  Internal
Revenue Code, in all events in a manner  consistent  with the  provisions of the
Investment Company Act.

    Participants in employer-sponsored retirement or savings plans must reinvest
all  distributions.   For  shareholders   investing  through  taxable  accounts,
distributions  will be  reinvested  unless  you elect to  receive  them in cash.
Distributions of less than $10 generally will be reinvested.  Distributions made
shortly  after a  purchase  by check  or ACH may be held up to 15 days.  You may
elect to have distributions on shares held in Individual Retirement Accounts and
403(b)  plans  paid  in  cash  only  if you are at  least  59 1/2  years  old or
permanently and totally disabled. Distribution checks normally are mailed within
seven days after the record date. Please consult our Investor Services Guide for
further information regarding your distribution options.

    A  distribution  of shares of the Fund does not  increase  the value of your
shares of your total return. At any given time the value of your shares includes
the  undistributed  net  gains,  if any,  realized  by the  Fund on the  sale of
portfolio securities,  and undistributed  dividends and interest received,  less
fund expenses.

    Because  undistributed gains and dividends are included in the value of your
shares prior to distribution, when they are distributed the value of your shares
will be  reduced  by the  amount  of the  distribution.  If you buy your  shares
through a taxable  account just before the  distribution,  you will pay the full
price for your shares,  and then receive a portion of the purchase price back as
a taxable distribution. See "Taxes," this page.

TAXES

    The Fund has elected to be taxed under  Subchapter M of the Internal Revenue
Code,  which means that to the extent its income is distributed to shareholders,
it pays no income taxes.

TAX-DEFERRED ACCOUNTS

    If Fund  shares  are  purchased  through  tax-deferred  accounts,  such as a
qualified  employer-sponsored  retirement  or savings  plan,  income and capital
gains  distributions  paid by the Fund will  generally not be subject to current
taxation,  but will  accumulate in your account under the plan on a tax-deferred
basis.

    Employer-sponsored  retirement and savings plans are governed by complex tax
rules.  If you elect to participate in your employer's  plan,  consult your plan
administrator,  your plan's  summary plan  description,  or a  professional  tax
advisor   regarding  the  tax   consequences  of   participation  in  the  plan,
contributions to, and withdrawals or distributions from the plan.

TAXABLE ACCOUNTS

    If Fund shares are purchased through taxable accounts,  distributions of net
investment  income  and net  short-term  capital  gains  are  taxable  to you as
ordinary income, except as described below. The dividends from net income of the
Fund do not qualify for the 70%  dividends-received  deduction for  corporations
since they are derived from interest  income.  Distributions  from net long-term
capital gains are taxable as long-term capital gains regardless of the length of
time you have held the shares on which such distributions are paid. However, you
should note that any loss  realized  upon the sale or  redemption of shares held
for six months or less will be treated as a long-term capital


14   ADDITIONAL INFORMATION YOU SHOULD KNOW       AMERICAN CENTURY INVESTMENTS


loss to the extent of any  distribution  of  long-term  capital gain to you with
respect to such shares.

    Distributions  are taxable to you  regardless  of whether  they are taken in
cash or reinvested,  even if the value of your shares is below your cost. If you
purchase shares shortly before a capital gain distribution,  you must pay income
taxes on the  distribution,  even though the value of your investment (plus cash
received, if any) will not have increased.  In addition,  the share price at the
time you purchase shares may include  unrealized gains in the securities held in
the  investment  portfolio  of the  Fund.  If  these  portfolio  securities  are
subsequently  sold and the gains are  realized,  they  will,  to the  extent not
offset by capital losses,  be paid to you as a distribution of capital gains and
will be taxable to you as short-term or long-term capital gains.

    In January of the year  following the  distribution,  if you own shares in a
taxable account, you will receive a Form 1099-DIV notifying you of the status of
your distributions for federal income tax purposes.

    Distributions may also be subject to state and local taxes, even if all or a
substantial  part  of  such  distribution  are  derived  from  interest  on U.S.
government  obligations  which,  if you received them directly,  would be exempt
from state income tax. However, most but not all states allow this tax exemption
to pass through to Fund  shareholders  when the Fund pays  distributions  to its
shareholders.  You should  consult your tax advisor about the tax status of such
distributions in your own state.

    If you have not complied  with certain  provisions  of the Internal  Revenue
Code,  either we or your  financial  intermediary  is required by federal law to
withhold  and remit to the IRS 31% of  reportable  payments  (which may  include
dividends,  capital gains  distributions  and  redemptions).  Those  regulations
require you to certify  that the Social  Security  number or tax  identification
number you provide is correct  and that you are not  subject to 31%  withholding
for  previous  under-reporting  to the  IRS.  You  will be  asked  to  make  the
appropriate certification on your application. Payments reported by us that omit
your Social  Security number or tax  identification  number will subject us to a
penalty  of $50,  which  will be  charged  against  your  account if you fail to
provide  the  certification  by  the  time  the  report  is  filed,  and  is not
refundable.

    Redemption of shares of the Fund (including  redemptions made in an exchange
transaction)  will be a taxable  transaction for federal income tax purposes and
shareholders  will generally  recognize a gain or loss in an amount equal to the
difference  between  the basis of the shares and the amount  received.  Assuming
that  shareholders hold such shares as a capital asset, the gain or loss will be
a capital gain or loss and will generally be long term if shareholders have held
such  shares for a period of more than one year.  If a loss is  realized  on the
redemption of Fund shares,  the reinvestment in additional Fund shares within 30
days before or after the  redemption  may be subject to the "wash sale" rules of
the Internal  Revenue Code,  resulting in a postponement  of the  recognition of
such loss for federal income tax purposes.

MANAGEMENT

INVESTMENT MANAGEMENT

    The Fund is the sole nondiversified  open-end series of the American Century
International  Bond Funds (the "Trust").  Under the laws of the  Commonwealth of
Massachusetts,  the Board of Trustees is  responsible  for managing the business
and affairs of the Trust. Acting pursuant to an investment  management agreement
entered into with the Fund, American Century Investment Management,  Inc. serves
as the investment  manager of the Fund. Its principal place of business American
Century Tower,  4500 Main Street,  Kansas City,  Missouri 64111. The Manager has
been  providing   investment  advisory  services  to  investment  companies  and
institutional clients since it was founded in 1958.

    The Manager supervises and manages the investment  portfolio of the Fund and
directs the purchase and sale of their investment securities.  It utilizes teams
of portfolio managers, assistant portfolio managers and analysts acting together
to supervise the management of the Fund's assets.

    JPMIM is the Fund's  investment  subadvisor.  JPMIM is a leading  manager of
pension funds,  institutional accounts, and private accounts, with approximately
$112 billion in assets under  management.  JPMIM makes investment  decisions for
the Fund in


PROSPECTUS                     ADDITIONAL INFORMATION YOU SHOULD KNOW     15


accordance with the Fund's  investment  objective,  policies,  and  restrictions
under the  supervision  of the  Manager  and the Board of  Trustees.  JPMIM is a
wholly owned subsidiary of J.P. Morgan & Co. Incorporated.

    The portfolio  manager  members of the teams  managing the Fund described in
this  Prospectus and their work experience for the last five years are listed as
follows:

    DOMINIC PEGLER,  Vice President,  is a fixed income  Portfolio  Manager.  He
Joined JPMIM London in 1996 after seven years at the Bank of England, serving as
an  economist  and in the  Reserves  Management  Department,  managing  the UK's
foreign  exchange  reserves.  His time at the Bank included a two-year term with
the Directorate of Monetary  Affairs.  Mr. Pegler holds a Bachelor's  degree and
Master's degree in Economics from the London School of Economics.

    DAVID SCHROEDER, Vice President, oversees JPMIM's management of the Fund and
has done so since  June 1997.  Mr.  Schroeder  is also of the teams that  manage
American    Century-Benham    Inflation-Adjusted    Treasury   Fund,    American
Century-Benham  Intermediate-Term  Treasury  Fund,  and the  series of  American
Century Target  Maturities  Trust. Mr. Schroeder joined the Manager in 1990 as a
Portfolio  Manager and serves as the group  leader of the  portfolio  management
teams which manage American  Century's U.S.  government and  international  bond
funds.

    For subadvisory services, the Manager pays JPMIM a monthly fee at the annual
rate of 0.20% of  average  daily  net  assets  up to $200  million  and 0.15% of
average  daily net assets in excess of $200  million.  For the fiscal year ended
December 31, 1996, the Manager paid JPMIM subadvisory fees equal to 0.19% of the
Fund's average daily net assets.

    The  activities  of the Manager are subject only to directions of the Fund's
Board of  Trustees.  The  Manager  pays  all the  expenses  of the  Fund  except
brokerage,  taxes,  portfolio  insurance,  interest,  fees and  expenses  of the
non-interested  person  Trustees  (including  counsel  fees)  and  extraordinary
expenses.

    For the services  provided to the Fund,  the Manager  receives a monthly fee
based on a percentage of the average net assets of the Fund.  The annual rate at
which this fee is assessed is determined monthly in a two-step process: First, a
fee rate  schedule is applied to the assets of all of the bond funds  managed by
the  Manager  (the  "Investment  Category  Fee").  Second,  a separate  fee rate
schedule  is applied to the  assets of all of the funds  managed by the  Manager
(the "Complex  Fee").  The Investment  Category Fee and the Complex Fee are then
added  to  determine  the  unified  management  fee  payable  by the Fund to the
Manager.  Currently,  the Investment Category Fee for the Fund is an annual rate
of 0.29% of the average net assets of the Fund.  The Complex Fee is currently an
annual rate of 0.30% of the average net assets of the Fund. Further  information
about the calculation of the annual management fee is contained in the Statement
of Additional Information.

    On the first  business day of each month,  the Fund pays a management fee to
the  Manager  for the  previous  month at the  specified  rate.  The fee for the
previous month is calculated by  multiplying  the applicable fee for the Fund by
the  aggregate  average  daily closing value of the Fund's net assets during the
previous  month by a fraction,  the  numerator of which is the number of days in
the previous month and the denominator of which is 365 (366 in leap years).

CODE OF ETHICS

    The Trust and the  Manager  have  adopted a Code of Ethics  which  restricts
personal  investing  practices by  employees of the Manager and its  affiliates.
Among other  provisions,  the Code of Ethics requires that employees with access
to information about the purchase or sale of securities in the Fund's portfolios
obtain  preclearance before executing personal trades. With respect to Portfolio
Managers  and  other  investment   personnel,   the  Code  of  Ethics  prohibits
acquisition  of securities  in an initial  public  offering,  as well as profits
derived from the purchase and sale of the same security within 60 calendar days.
These  provisions  are  designed  to  ensure  that  the  interests  of the  Fund
shareholders come before the interests of the people who manage the Fund.

TRANSFER AND ADMINISTRATIVE SERVICES

    American  Century  Services  Corporation,  4500 Main  Street,  Kansas  City,
Missouri 64111, acts as transfer agent and dividend-paying agent for the Fund.

of his ownership of a majority of its common stock.

DISTRIBUTION OF FUND SHARES

    The Fund's shares are distributed by American Century  Investment  Services,
Inc. (the  "Distributor"),  a registered  broker-dealer  and an affiliate of the
Manager.  As agent for the Fund and the  Manager,  the  Distributor  enters into
contracts  with various  banks,  broker-dealers,  insurance  companies and other
financial  intermediaries  with respect to the sale of the Fund's  shares and/or
the use of the Fund's shares in various financial  services.  The Manager (or an
affiliate) pays all expenses  incurred in promoting  sales of, and  distributing
the  Advisor  Class and in  securing  such  services  out of the Rule 12b-1 fees
described in the section that follows.

SERVICE AND DISTRIBUTION FEES

    Rule  12b-1  adopted by the SEC under the  Investment  Company  Act  permits
investment  companies  that  adopt  a  written  plan  to  pay  certain  expenses
associated  with the  distribution  of their shares.  Pursuant to that rule, the
Fund's Board of Trustees and the initial shareholder of the Fund's Advisor Class
shares have approved and adopted a Master Distribution and Shareholder  Services
Plan  (the  "Plan").  Pursuant  to the  Plan,  each  Fund  pays  the  Manager  a
shareholder  services  fee and a  distribution  fee,  each equal to 0.25% (for a
total of 0.50%) per annum of the  average  daily net assets of the shares of the
Fund's Advisor Class.  The  shareholder  services fee is paid for the purpose of
paying the costs of securing certain  shareholder and  administrative  services,
and the  distribution  fee is paid  for the  purpose  of  paying  the  costs  of
providing various distribution  services. All or a portion of such fees are paid
by the  Manager  to the  banks,  broker-dealers,  insurance  companies  or other
financial intermediaries through which such shares are made available.

    The Plan has been adopted and will be  administered  in accordance  with the
requirements  of Rule 12b-1 under the  Investment  Company Act.  For  additional
information  about  the  Plan  and  its  terms,  see  "Master  Distribution  and
Shareholder Services Plan" in the Statement of Additional Information. Fees paid
pursuant to the Plan may be paid for shareholder services and the maintenance of
accounts and therefore may constitute  "service fees" for purposes of applicable
rules of the National Association of Securities Dealers.

FURTHER INFORMATION ABOUT AMERICAN CENTURY

    The Fund is an open-end  management  investment  company.  Its  business and
affairs  are  managed  by its  officers  under  the  direction  of its  Board of
Trustees.

    The  principal  office of the Trust is  American  Century  Tower,  4500 Main
Street, P. O. Box 419385, Kansas City, Missouri 64141-6385. All inquiries may be
made by mail to that address,  or by telephone to 1-800-345-3533  (international
calls: 816-531-5575).

    The Fund is an  individual  series of the Trust which issues  shares with no
par value. Each series is commonly referred to as a fund. Currently, the Fund is
the only existing series of the Trust.  In the event that  additional  series of
the Trust are  created,  the assets  belonging to each series of shares are held
separately by the custodian and in effect each series is a separate fund.

    American  Century  International  Bond Funds  offers two classes of the Fund
offered by this  Prospectus:  an Investor Class and an Advisor Class. The shares
offered by this Prospectus are Advisor Class shares.

    The  Investor  Class  of  shares  is  primarily  made  available  to  retail
investors.  This  other  class has  different  fees,  expenses,  and/or  minimum
investment  requirements  than the  Advisor  Class.  The  difference  in the fee
structures  among the classes is the result of their separate  arrangements  for
shareholder  and  distribution  services and not the result of any difference in
amounts  charged  by  the  Manager  for  core  investment   advisory   services.
Accordingly, the core investment advisory expenses do not vary by class.


PROSPECTUS                   ADDITIONAL INFORMATION YOU SHOULD KNOW    17


    Different  fees  and  expenses  will  affect  performance.   For  additional
information  concerning the Investor  class of shares,  call one of our Investor
Services Representatives at 1-800-345-2021.

    Except as described  below,  all classes of shares of a Fund have  identical
voting,  dividend,   liquidation  and  other  rights,  preferences,   terms  and
conditions.  The only  differences  among the various classes are (a) each class
may be subject to different  expenses specific to that class, (b) each class has
a different identifying designation or name, (c) each class has exclusive voting
rights with respect to matters solely  affecting such class,  and (d) each class
may have different exchange privileges.

    Each  share,  irrespective  of series or class,  is entitled to one vote for
each dollar of net asset value applicable to such share on all questions, except
for those  matters  which must be voted on  separately by the series or class of
shares affected.  Matters affecting only one series or class are voted upon only
by that series or class.

    Shares have  non-cumulative  voting rights,  which means that the holders of
more than 50% of the votes cast in an election of Trustees  can elect all of the
Trustees if they choose to do so, and in such event the holders of the remaining
votes will not be able to elect any person or persons to the Board of Trustees.

    Unless required by the Investment  Company Act, it will not be necessary for
the Trust to hold annual meetings of shareholders. As a result, shareholders may
not vote each year on the election of Trustees or the  appointment  of auditors.
However,  pursuant to the Trust's by-laws, the holders of shares representing at
least 10% of the votes  entitled  to be cast may  request  that the Trust hold a
special meeting of shareholders. The Trust will assist in the communication with
other shareholders.

    WE RESERVE THE RIGHT TO CHANGE ANY OF OUR POLICIES, PRACTICES AND PROCEDURES
DESCRIBED IN THIS PROSPECTUS, INCLUDING THE STATEMENT OF ADDITIONAL INFORMATION,
WITHOUT  SHAREHOLDER  APPROVAL  EXCEPT  IN  THOSE  INSTANCES  WHERE  SHAREHOLDER
APPROVAL IS EXPRESSLY REQUIRED.

    THIS PROSPECTUS  CONSTITUTES AN OFFER TO SELL SECURITIES OF THE FUND ONLY IN
THOSE STATES WHERE THE FUND'S SHARES HAVE BEEN REGISTERED OR OTHERWISE QUALIFIED
FOR SALE. THE FUND WILL NOT ACCEPT  APPLICATIONS FROM PERSONS RESIDING IN STATES
WHERE THE FUND'S SHARES ARE NOT REGISTERED.

INVESTMENT POLICIES, TECHNIQUES AND RISK FACTORS

   
    The following  pages provide a more detailed  description  of securities and
investment  practices identified in the Prospectus and the risks associated with
these  practices.  Unless  otherwise  noted,  the  policies  described  in  this
Statement of Additional  Information  are not  fundamental and may be changed by
the Board of Trustees.
    

U.S. GOVERNMENT SECURITIES

    U.S.  government  securities  include bills,  notes, and bonds issued by the
U.S.   Treasury   and   securities   issued  or   guaranteed   by   agencies  or
instrumentalities of the U.S. government.

    Some U.S.  government  securities are supported by the direct full faith and
credit pledge of the U.S.  government;  others are supported by the right of the
issuer to borrow from the U.S.  Treasury;  others,  such as securities issued by
the  Federal  National  Mortgage   Association  (FNMA),  are  supported  by  the
discretionary  authority  of the  U.S.  government  to  purchase  the  agencies'
obligations;  and others  are  supported  only by the  credit of the  issuing or
guaranteeing  instrumentality.  There is no assurance  that the U.S.  government
will provide financial support to an  instrumentality it sponsors when it is not
obligated by law to do so.

REPURCHASE AGREEMENTS

    In a repurchase  agreement (a "repo"), the Fund buys a security at one price
and simultaneously  agrees to sell it back to the seller at an agreed upon price
on a specified date (usually  within seven days from the date of purchase) or on
demand.  The  repurchase  price  exceeds  the  purchase  price by an amount that
reflects an  agreed-upon  rate of return and that is  unrelated  to the interest
rate on the underlying security. Delay or losses could result if the other party
to the agreement defaults or becomes bankrupt.

    American Century  Investment  Management,  Inc. (the "Manager")  attempts to
minimize the risks associated with repurchase  agreements by adhering to written
guidelines which govern repurchase agreements.  These guidelines strictly govern
(1) the type of  securities  which may be  acquired  and held  under  repurchase
agreements; (2) collateral requirements for sellers under repurchase agreements;
(3) the  amount of the Fund's net assets  that may be  committed  to  repurchase
agreements  that mature in more than seven days; and (4) the manner in which the
Fund  must  take  delivery  of  securities  subject  to  repurchase  agreements.
Moreover,  the Board of Trustees reviews and approves, on a quarterly basis, the
creditworthiness of brokers, dealers and banks with whom the Fund may enter into
repurchase agreements.  The Fund may enter into a repurchase agreement only with
an entity that appears on a list of those which have been  approved by the Board
as sufficiently creditworthy.

    The Fund  has  received  permission  from  the SEC to  participate  in joint
repurchase  agreements  collateralized by U.S. government  securities with other
mutual funds advised by the Manager or its affiliates.  Joint repos are expected
to  increase  the  income  the Fund  can earn  from  repo  transactions  without
increasing the risks associated with these transactions.

   
    Under the  Investment  Company Act of 1940 (the  "Investment  Company Act"),
repurchase agreements are considered loans.
    

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

    The Fund may engage in securities  transactions  on a when-issued or forward
commitment basis, in which the transaction price and yield are each fixed at the
time the  commitment  is made,  but payment and delivery  occur at a future date
(typically 15 to 45 days later).

    When purchasing securities on a when-issued or forward commitment basis, the
Fund assumes the rights and risks of ownership, including the risks of price and
yield fluctuations.  Although the Fund will make commitments to purchase or sell
securities with the intention of actually  receiving or delivering  them, it may
sell the securities  before the settlement date if doing so is deemed  advisable
as a matter of investment strategy.

    In purchasing  securities on a when-issued or forward  commitment basis, the
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash or appropriate  liquid assets including equity securities and
debt securities of any grade in an amount sufficient to meet the purchase price.
When the time comes to pay for the  when-issued  securities,  the Fund will meet
its obligations with available cash, through the sale of securi-


2                                               AMERICAN CENTURY INVESTMENTS


ties,  or,  although  it would not  normally  expect to do so,  by  selling  the
when-issued securities themselves (which may have a market value greater or less
than the Fund's payment  obligation).  Selling securities to meet when-issued or
forward commitment obligations may generate taxable capital gains or losses.

SECURITIES LENDING

    The Fund may lend its portfolio  securities to earn additional  income. If a
borrower  defaulted on a securities  loan, the Fund could  experience  delays in
recovering  the  securities  it loaned;  if the value of the  loaned  securities
increased over the value of the collateral, the Fund could suffer a loss.

    To minimize the risk of default on securities  loans, the Manager adheres to
guidelines  prescribed by the Board of Trustees governing lending of securities.
These guidelines strictly govern (1) the type and amount of collateral that must
be received by the Fund;  (2) the  circumstances  under which  additions to that
collateral must be made by borrowers; (3) the return received by the Fund on the
loaned securities; (4) the limitations on the percentage of Fund assets on loan;
and (5) the  credit  standards  applied in  evaluating  potential  borrowers  of
portfolio securities. In addition, the guidelines require that the Fund have the
option  to  terminate  any  loan of a  portfolio  security  at any  time and set
requirements for recovery of securities from borrowers.

FOREIGN CURRENCY EXCHANGE TRANSACTIONS

    The Fund expects to exchange dollars for the Fund's  underlying  currencies,
and  vice  versa,  in the  normal  course  of  managing  the  Fund's  underlying
investments.  JPMIM does not expect that the Fund will hold currency that is not
earning income on a regular basis,  although the Fund may do so temporarily when
suitable  investments are not available.  The Fund may exchange  currencies on a
"spot" basis (i.e.,  for prompt  delivery and  settlement),  or by entering into
forward  currency  exchange  contracts (also called forward  contracts) or other
contracts to purchase and sell  currencies  for settlement at a future date. The
Fund will incur costs in converting assets from one currency to another. Foreign
exchange dealers may charge a fee for conversion; in addition, they also realize
a profit based on the difference  (i.e., the spread) between the prices at which
they buy and sell various  currencies in the spot and forward  markets.  Thus, a
dealer  may  offer  to sell a  foreign  currency  to the Fund at one  rate,  and
repurchase  it at a lesser rate should the fund desire to resell the currency to
the dealer.

    Forward  contracts  are  agreements  to  exchange a  specific  amount of one
currency for a specified amount of another at a future date. The date may be any
agreed  fixed  number  of days in the  future.  The  amount  of  currency  to be
exchanged,  the price at which the exchange will take place, and the date of the
exchange are negotiated when the Fund enters into the contract and are fixed for
the term of the contract.  Forward  contracts are traded in an interbank  market
conducted directly between currency traders (usually large commercial banks) and
their customers.  A forward contract generally has no deposit requirement and is
consummated without payment of any commission.  However, the Fund may enter into
forward contracts with deposit requirements or commissions.

    At the maturity of a forward contract, the Fund may complete the contract by
paying for and receiving the underlying  currency,  may seek to roll forward its
contractual  obligation by entering into an  "offsetting"  transaction  with the
same  currency  trader  and  paying or  receiving  the  difference  between  the
contractual  exchange rate and the current  exchange  rate. The Fund may also be
able  to  enter  into  an  offsetting  contract  prior  to the  maturity  of the
underlying  contract.  This practice is sometimes referred to as "cross hedging"
and may be employed if, for example,  JPMIM  believes that one foreign  currency
(in which a portion of the Fund's  foreign  currency  holdings are  denominated)
will  change in value  relative  to the U.S.  dollar  differently  than  another
foreign  currency.  There is no assurance that offsetting  transactions,  or new
forward contracts, will always be available to the Fund.

    Investors  should  realize  that  the  use of  forward  contracts  does  not
eliminate  fluctuations  in  the  underlying  prices  of  the  securities.  Such
contracts  simply establish a rate of exchange that the Fund can achieve at some
future point in time. Additionally, although such contracts tend to minimize the
risk of loss due to  fluctuations  in the value of the hedged currency when used
as a hedge  against  foreign  currency  declines,  at the same time they tend to
limit any potential gain which might result from the


STATEMENT OF ADDITIONAL INFORMATION                                   3


change in the value of such currency.

    Because  investments  in,  and  redemptions  from,  the Fund will be in U.S.
dollars, JPMIM expects that the Fund's normal investment activity will involve a
significant  amount of currency  exchange.  For  example,  the Fund may exchange
dollars  for its  underlying  foreign  currencies  for  dollars in order to meet
shareholder  redemption  requests or to pay expenses.  These transactions may be
executed in the spot or forward markets.

    In addition,  the Fund may combine  forward  transactions  in its underlying
currency with investments in U.S. dollar-denominated  instruments, in an attempt
to construct an investment position whose overall performance will be similar to
that of a security  denominated  in its  underlying  currency.  If the amount of
dollars to be exchanged is properly  matched with the  anticipated  value of the
dollar-denominated  securities, the Fund should be able to "lock in" the foreign
currency value of the securities,  and the Fund's overall investment return from
the combined  position should be similar to the return from purchasing a foreign
currency-denominated  instrument. This is sometimes referred to as a "synthetic"
investment position or a "position hedge."

    The execution of a synthetic  investment position may not be successful.  It
is impossible to forecast  with  absolute  precision  what the dollar value of a
particular   security   will  be  at  any  given   time.   If  the  value  of  a
dollar-denominated  security is not exactly  matched with the Fund's  obligation
under the forward  contract on the  contract's  maturity  date,  the Fund may be
exposed to some risk of loss from fluctuation of the dollar. Although JPMIM will
attempt to hold such  mismatchings to a minimum,  there can be no assurance that
JPMIM will be successful in doing so.

FUTURES AND OPTIONS TRANSACTIONS

    FUTURES  CONTRACTS provide for the sale by one party and purchase by another
party of a specific  security  at a  specified  future  time and price.  Futures
contracts  are traded on  national  futures  exchanges.  Futures  exchanges  and
trading are regulated under the Commodity  Exchange Act by the Commodity Futures
Trading Commission (CFTC), a U.S. government agency.

    Although  futures  contracts,  by their terms,  call for actual  delivery or
acceptance of the underlying securities,  in most cases the contracts are closed
out before the settlement date. Closing out a futures position is done by taking
an opposite position in an identical contract (i.e.,  buying a contract that has
previously been sold, or selling a contract that has previously been bought).

    To initiate and maintain open  positions in futures  contracts,  the Fund is
required to make a good faith margin  deposit in cash or  government  securities
with a broker or custodian. A margin deposit is intended to assure completion of
the contract  (delivery or acceptance of the  underlying  security) if it is not
terminated  prior  to  the  specified  delivery  date.  Minimum  initial  margin
requirements  are  established by the futures  exchanges and may be revised.  In
addition,  brokers may establish  deposit  requirements that are higher than the
exchange minimums.

    After a futures  contract  position is opened,  the value of the contract is
marked to market daily. If the futures contract price changes to the extent that
the margin on deposit does not satisfy margin requirements,  the contract holder
is required to pay additional  "variation"  margin.  Conversely,  changes in the
contract  value may reduce the  required  margin,  resulting  in a repayment  of
excess margin to the contract  holder.  Variation margin payments are made to or
from  the  futures  broker  as  long as the  contract  remains  open  and do not
constitute   margin   transactions   for  purposes  of  the  Fund's   investment
restrictions.

    Those  who trade  futures  contracts  may be  broadly  classified  as either
"hedgers" or "speculators."  Hedgers,  such as the Fund, use the futures markets
primarily to offset unfavorable  changes in the value of securities they hold or
expect to acquire for investment  purposes.  Speculators  are less likely to own
the securities  underlying the futures  contracts they trade and are more likely
to use  futures  contracts  with  the  expectation  of  realizing  profits  from
fluctuations  in the  prices  of the  underlying  securities.  The Fund will not
utilize futures contracts for speculative purposes.

    Although  techniques  other than trading  futures  contracts  can be used to
control the Fund's exposure to market fluctuations, the use of futures contracts
may be a more  effective  means of hedging  this  exposure.  While the Fund pays
brokerage commissions in connection with opening and closing out futures


4                                                AMERICAN CENTURY INVESTMENTS


positions,  these  costs are lower than the  transaction  costs  incurred in the
purchase and sale of the underlying securities.

    PURCHASING  PUT AND CALL  OPTIONS.  By  purchasing  a put  option,  the Fund
obtains  the right  (but not the  obligation)  to sell the  option's  underlying
instrument at a fixed strike price. In return for this right,  the Fund pays the
current market price for the option (known as the option premium).  Options have
various types of underlying instruments,  including specific securities, indexes
of securities prices, and futures contracts. The Fund may terminate its position
in a put option it has purchased by allowing it to expire or by  exercising  the
option.  If the  option is  allowed  to  expire,  the Fund will lose the  entire
premium it paid. If the Fund exercises the option,  it completes the sale of the
underlying  instrument  at the strike price.  The Fund may also  terminate a put
option  position by closing it out in the secondary  market at its current price
if a liquid secondary market exists.

    The buyer of a typical  put option can expect to realize a gain if  security
prices fall substantially.  However,  if the underlying  instrument's price does
not fall enough to offset the cost of  purchasing  the  option,  a put buyer can
expect to suffer a loss (limited to the amount of the premium paid, plus related
transaction costs).

    The  features  of call  options  are  essentially  the  same as those of put
options,  except  that the  purchaser  of a call  option  obtains  the  right to
purchase,  rather than sell,  the underlying  instrument at the option's  strike
price.  A call buyer  typically  attempts  to  participate  in  potential  price
increases  of the  underlying  instrument  with risk  limited to the cost of the
option if security prices fall. At the same time, the buyer can expect to suffer
a loss if  security  prices do not rise  sufficiently  to offset the cost of the
option.

    WRITING PUT AND CALL OPTIONS.  If the Fund writes a put option, it takes the
opposite  side of the  transaction  from the option's  purchaser.  In return for
receipt of the premium,  the Fund assumes the obligation to pay the strike price
for the option's  underlying  instrument  if the other party chooses to exercise
the  option.  When  writing  an option on a futures  contract,  the Fund will be
required to make margin payments to a broker or custodian as described above for
futures  contracts.  The Fund may seek to terminate its position in a put option
it writes before  exercise by closing out the option in the secondary  market at
its current  price.  However,  if the  secondary  market is not liquid for a put
option the Fund has  written,  the Fund must  continue to be prepared to pay the
strike price while the option is outstanding,  regardless of price changes,  and
must continue to set aside assets to cover its position.

    If security  prices  rise, a put writer  would  generally  expect to profit,
although  the gain would be limited to the amount of the  premium  received.  If
security  prices remain the same over time,  the writer would likely also profit
by being able to close out the option at a lower price. If security prices fall,
the put writer would expect to suffer a loss.  This loss should be less than the
loss from purchasing the underlying  instrument directly,  however,  because the
premium  received  for writing  the option  should  mitigate  the effects of the
decline.

    Writing a call option  obligates  the Fund to sell or deliver  the  option's
underlying  instrument  in return for the  strike  price  upon  exercise  of the
option.  The  characteristics  of writing  call  options are similar to those of
writing put  options,  except  that  writing  calls  generally  is a  profitable
strategy  if prices  remain  the same or fall.  Through  receipt  of the  option
premium,  a call writer  mitigates the effects of a price  decline.  At the same
time,  because  a call  writer  must  be  prepared  to  deliver  the  underlying
instrument  in return for the strike price even if its current value is greater,
a call writer gives up some ability to participate in security price increases.

    COMBINED  POSITIONS.  The Fund may purchase and write options in combination
with one another, or in combination with futures or forward contracts, to adjust
the risk and return  characteristics of the overall position.  For example,  the
Fund may  purchase a put option and write a call  option on the same  underlying
instrument   to   construct   a   combined   position   whose  risk  and  return
characteristics  are  similar to selling a futures  contract.  Another  possible
combined  position  would involve  writing a call option at one strike price and
buying a call  option at a lower  price to reduce the risk of the  written  call
option in the event of a substantial  price increase.  Because  combined options
positions involve multiple trades,  they result in higher  transaction costs and
may be more difficult to open


STATEMENT OF ADDITIONAL INFORMATION                                     5


and close out.

    OVER-THE-COUNTER   OPTIONS.   Unlike  exchange-traded   options,  which  are
standardized  with  respect  to  the  underlying  instrument,  expiration  date,
contract size, and strike price, the terms of  over-the-counter  ("OTC") options
(options not traded on exchanges)  generally are established through negotiation
with the other  party to the option  contract.  While  this type of  arrangement
allows  the Fund  greater  flexibility  to tailor an  option to its  needs,  OTC
options  generally  involve  greater credit risk than  exchange-traded  options,
which are guaranteed by the clearing  organizations  of the exchanges where they
are traded.  The risk of  illiquidity  is also greater with OTC options  because
these  options  generally can be closed out only by  negotiation  with the other
party to the option.

    OPTIONS ON FUTURES. By purchasing an option on a futures contract,  the Fund
obtains the right,  but not the obligation,  to sell the futures contract (a put
option) or to buy the contract (a call option) at a fixed  "strike"  price.  The
Fund can  terminate  its position in a put option by allowing it to expire or by
exercising the option.  If the option is exercised,  the Fund completes the sale
of the  underlying  security  at the  strike  price.  Purchasing  an option on a
futures  contract does not require the Fund to make margin  payments  unless the
option is exercised.

    CORRELATION OF PRICE CHANGES. Because there are a limited number of types of
exchange-traded   futures  and  options   contracts,   it  is  likely  that  the
standardized   contracts   available  will  not  match  the  Fund's  current  or
anticipated  investments  exactly.  The Fund may invest in futures  and  options
contracts  based on securities  with  different  issuers,  maturities,  or other
characteristics  from the securities in which it typically invests (for example,
by hedging  intermediate-term  securities  with a futures  contract  based on an
index of long-term bond prices);  this involves a risk that the futures position
will not track the performance of the Fund's other investments.

    Options and futures  prices can diverge from the prices of their  underlying
instruments  even if the underlying  instruments  correlate well with the Fund's
investments.  Options and futures prices are affected by factors such as current
and  anticipated  short-term  interest  rates,  changes  in  volatility  of  the
underlying instrument,  and the time remaining until expiration of the contract,
which may not affect  security  prices the same way.  Imperfect  correlation may
also result from differing  levels of demand in the options and futures  markets
and securities markets,  from structural  differences in how options and futures
and  securities are traded,  or from the  imposition of daily price  fluctuation
limits or trading  halts.  The Fund may  purchase  or sell  options  and futures
contracts  with a greater or lesser value than the securities it wishes to hedge
or intends to purchase in an effort to compensate for  differences in volatility
between the contract and the securities,  although this may not be successful in
all  cases.  If price  changes in the Fund's  options or futures  positions  are
poorly correlated with its other investments,  the positions may fail to produce
anticipated  gains or  result in  losses  that are not  offset by gains in other
investments.

    FUTURES AND OPTIONS CONTRACTS RELATING TO FOREIGN  CURRENCIES.  The Fund may
purchase and sell currency  futures and purchase and write  currency  options to
increase or decrease its exposure to different  foreign  currencies.  A Fund may
also purchase and write currency  options in connection with currency futures or
forward contracts.

    Currency  futures   contracts  are  similar  to  forward  currency  exchange
contracts,  except that they are traded on exchanges and have standard  contract
sizes and delivery dates.  Most currency  futures  contracts call for payment or
delivery in U.S. dollars.

    The uses and risks of  currency  futures  are  similar  to those of  futures
relating to securities or indexes,  as described above.  Currency futures values
can be expected to correlate  with  exchange  rates,  but may not reflect  other
factors that affect the value of the Fund's  investments.  A currency hedge, for
example, should protect a German-mark-denominated security from a decline in the
German mark, but it will not protect the Fund against a price decline  resulting
from a deterioration in the issuer's creditworthiness.

    LIQUIDITY OF FUTURES  CONTRACTS  AND OPTIONS.  There is no assurance  that a
liquid secondary market will exist for any particular futures contract or option
at any  particular  time.  Options may have  relatively  low trading  volume and
liquidity if their strike  prices are not close to the  underlying  instrument's
current  price.  In addition,  exchanges may establish  daily price  fluctuation
limits for futures contracts and options


6                                              AMERICAN CENTURY INVESTMENTS


and may halt  trading if a contract's  price moves upward or downward  more than
the limit on a given day. On volatile  trading  days when the price  fluctuation
limit is reached or a trading halt is imposed, it may be impossible for the Fund
to enter into new  positions or close out existing  positions.  If the secondary
market for a contract  was not liquid,  because of price  fluctuation  limits or
otherwise,  prompt  liquidation of unfavorable  positions  could be difficult or
impossible,  and the Fund could be required to continue holding a position until
delivery  or  expiration  regardless  of  changes  in  its  value.  Under  these
circumstances,  the Fund's  access to assets held to cover its future  positions
could also be impaired.

    Futures and options  trading on foreign  exchanges  may not be  regulated as
effectively  as similar  transactions  in the U.S. and may not involve  clearing
mechanisms or guarantees  similar to those  available in the U.S. The value of a
futures  contract  or  option  traded  on a foreign  exchange  may be  adversely
affected by the imposition of different  exercise and settlement terms,  trading
procedures, and margin requirements, and lesser trading volume.

    RESTRICTIONS ON THE USE OF FUTURES CONTRACTS AND OPTIONS. The Fund has filed
a notice of  eligibility  for exclusion as a "commodity  pool operator" with the
Commodity   Futures  Trading   Commission   (CFTC)  and  the  National   Futures
Association, which regulates trading in the futures markets. The Fund intends to
comply with Section 4.5 of the  regulations  under the  Commodity  Exchange Act,
which  limits the extent to which the Fund can commit  assets to initial  margin
deposits and options premiums.

    The Fund may enter into futures transactions (including related options) for
hedging purposes without regard to the percentage of assets committed to initial
margin and for other than hedging  purposes  provided  that assets  committed to
initial margin deposits on such instruments, plus premiums paid for open futures
options   positions,   less  the  amount  by  which  any  such   positions   are
"in-the-money,"  do not  exceed 5% of the  Fund's  total  assets.  To the extent
required by law, the Fund will set aside cash and appropriate liquid assets in a
segregated  account to cover its  obligations  related to futures  contracts and
options.

    Financial  futures  or  options  purchased  or  sold  by the  Fund  will  be
standardized  and traded through the facilities of a U.S. or foreign  securities
association or listed on a U.S. or foreign  securities or commodities  exchange,
board of trade, or similar entity,  or quoted on an automatic  quotation system,
except that the Fund may effect  transactions in  over-the-counter  options with
primary U.S.  government  securities  dealers  recognized by the Federal Reserve
Bank of New  York.  In  addition,  the Fund has  undertaken  to limit  aggregate
premiums  paid on all options  purchased  by the Fund to no more than 20% of the
Fund's total assets.

    The Fund intends to comply with tax rules applicable to regulated investment
companies,  including  a  requirement  that  capital  gains  from  the  sale  of
securities  held less than  three  months  constitute  less than 30% of a Fund's
gross income for each fiscal year.  Gains on some futures  contracts and options
are included in this 30% calculation,  which may limit the Fund's investments in
these instruments.

INVESTMENT RESTRICTIONS

    The Fund's  investment  restrictions  are set forth below.  These investment
restrictions  are  fundamental  and may not be changed  without  approval  of "a
majority of the outstanding votes of shareholders" of the Fund, as determined in
accordance with the Investment Company Act.

    AS A FUNDAMENTAL POLICY, THE FUND SHALL NOT:

  1)     issue senior securities, except as permitted under the Investment
         Company Act of 1940.

  2)     borrow  money,  except that the Fund may borrow money for  temporary or
         emergency  purposes (not for leveraging or investment) in an amount not
         exceeding  33-1/3% of the Fund's  total  assets  (including  the amount
         borrowed) less liabilities (other than borrowings).

  3)     lend any  security  or make any other  loan if, as a result,  more than
         33-1/3%  of the Fund's  total  assets  would be lent to other  parties,
         except,  (i) through the purchase of debt securities in accordance with
         its investment objective, policies and limitations, or (ii) by engaging
         in repurchase agreements with respect to portfolio securities.

  4)     purchase or sell real estate  unless  acquired as a result of ownership
         of securities or other  instruments.  This policy shall not prevent the
         Fund from investment in securities or other instruments  backed by real
         estate or  securities  of  companies  that  deal in real  estate or are
         engaged in the real estate business.

  5)     concentrate  its  investments  in securities of issuers in a particular
         industry  (other  than  securities  issued  or  guaranteed  by the U.S.
         government or any of its agencies or instrumentalities).

  6)     act as an  underwriter  of securities  issued by others,  except to the
         extent  that the Fund  may be  considered  an  underwriter  within  the
         meaning of the Securities Act of 1933 in the  disposition of restricted
         securities.

  7)     purchase or sell physical  commodities  unless  acquired as a result of
         ownership  of  securities  or other  instruments;  provided  that  this
         limitation  shall not  prohibit  the Fund from  purchasing  or  selling
         options and futures  contracts or from investing in securities or other
         instruments backed by physical commodities.

  8)     invest for purposes of exercising control over management.

    In  addition,  the Fund is subject to the  following  additional  investment
restrictions  which  are not  fundamental  and may be  changed  by the  Board of
Trustees.

    AS AN OPERATING POLICY, THE FUND:

  a)     to meet  federal tax  requirements  for  qualification  as a "regulated
         investment company," limits its investment so that at the close of each
         quarter of its taxable  year:  (i) with regard to at least 50% of total
         assets,  no more than 5% of total assets are invested in the securities
         of a single  issuer,  and (ii) no more  than  25% of total  assets  are
         invested in the securities of a single issuer. Limitations (i) and (ii)
         do not apply to  "Government  securities"  as defined  for  federal tax
         purposes.  The Fund does not,  with respect to 75% of its total assets,
         currently  intend to purchase the  securities of any issuer (other than
         securities  issued or guaranteed  by the U.S.  government or any of its
         agencies or instrumentalities)  if, as a result thereof, the Fund would
         own more than 10% or the outstanding voting securities of such issuer.

  b)     shall not purchase additional  investment securities at any time during
         which outstanding borrowings exceed 5% of the total assets of the Fund.

  c)     shall not purchase  any  security or enter into a repurchase  agreement
         if, as a result,  more than 15% of its net assets  would be invested in
         repurchase  agreements not entitling the holder to payment of principal
         and interest  within seven days and in securities  that are illiquid by
         virtue of legal or contractual restrictions on resale or the absence of
         a readily available market.

  d)     shall  not sell  securities  short,  unless it owns or has the right to
         obtain securities  equivalent in kind and amount to the securities sold
         short, and provided that  transactions in futures contracts and options
         are not deemed to constitute selling securities short.

  e)     shall not  purchase  securities  on  margin,  except  that the Fund may
         obtain such  short-term  credits as are  necessary for the clearance of
         transactions,  and provided  that margin  payments in  connection  with
         futures contracts and options on futures contracts shall not constitute
         purchasing securities on margin.

    For purposes of the investment restriction (5), relating to concentration, a
Fund shall not  purchase  any  securities  which  would cause 25% or more of the
value of the Fund's  total  assets at the time of purchase to be invested in the
securities of one or more issuers conducting their principal business activities
in the same industry,  provided that (a) there is no limitation  with respect to
obligations issued or guaranteed by the U.S. government, any state, territory or
possession  of the United  States,  the  District  of  Columbia  or any of their
authorities,   agencies,   instrumentalities   or  political   subdivisions  and
repurchase  agreements  secured by such  instruments,  (b) wholly-owned  finance
companies  will be considered to be in the  industries of their parents if their
activities are primarily related to financing the activities of the parents, (c)
utilities will be divided  according to their  services,  for example,  gas, gas
transmission, electric and gas, electric and telephone will each be consid-


8                                               AMERICAN CENTURY INVESTMENTS


ered a separate industry, and (d) personal credit and business credit businesses
will be considered separate industries.

    Unless  otherwise   indicated,   percentage   limitations  included  in  the
restrictions apply at the time transactions are entered into.  Accordingly,  any
later  increase or decrease  beyond the specified  limitation  resulting  from a
change in the Fund's net assets will not be considered in determining whether it
has complied with its investment restrictions.

PORTFOLIO TRANSACTIONS

    In selecting  broker-dealers to execute  transactions on behalf of the Fund,
JPMIM seeks the best net price and  execution  available.  In assessing the best
net price and execution available for any Fund transaction,  JPMIM will consider
all factors it deems relevant including,  but not limited to, (i) the breadth of
the market for the security, (ii) the price of the security, (iii) the financial
condition  and  execution   capability  of  the  broker-dealer,   and  (iv)  the
reasonableness  of  any  commission  for  the  specific  transaction.  When  the
execution and price offered by two or more broker-dealers are comparable,  JPMIM
may,  with  discretion,  in  recognition  of the value of  brokerage or research
services provided by the broker-dealer,  purchase and sell portfolio  securities
to and from broker-dealers who provide the Fund with research and other services
provided,  however,  that in all instances best net price and execution shall be
the  controlling  factor,  and in no event may JPMIM  pay to a  broker-dealer  a
commission in excess of that which another  broker-dealer would have charged for
effecting the same transaction.

    When  JPMIM  deems  the  purchase  or sale of a  security  to be in the best
interest  of the  Fund as well  as its  other  clients,  it may,  to the  extent
permitted by applicable  law,  aggregate the  securities to be sold or purchased
with those of its other clients.  In such an event, the allocation of securities
so  purchased  or sold will be made by JPMIM in a manner it  considers to be the
most equitable and consistent with its fiduciary obligations to the Fund and its
other clients.

    JPMIM is authorized  to execute such  documents as may be required to affect
forward foreign currency exchange  contracts on behalf of the Fund. In selecting
counterparties for such contracts,  JPMIM seeks the best overall terms available
and executes or directs the execution of all such  transactions  as permitted by
law and consistent with the best interest of the Fund.

    The Fund's portfolio  turnover rates are listed in the Financial  Highlights
in the Prospectus.

TRANSACTIONS WITH JPMIM AFFILIATES

    As described in further detail under the section titled "Investment Advisory
Services,"  JPMIM is subadvisor to the Fund pursuant to an agreement with Benham
Management Corporation.

    JPMIM, Morgan Guaranty Trust Company of New York ("Morgan  Guaranty"),  J.P.
Morgan  Securities  Inc., and J.P.  Morgan  Securities  Limited are wholly owned
subsidiaries  of  J.P.  Morgan  &  Co.   Incorporated,   hereafter  referred  to
collectively as "Morgan affiliates."

    J.  P.  Morgan  Securities  Inc.  is a  broker-dealer  registered  with  the
Securities and Exchange  Commission and is a member of the National  Association
of Securities Dealers.  It is active as a dealer in U.S.  government  securities
and an underwriter of and dealer in U.S.  government agency securities and money
market instruments.

    J.P.  Morgan  Securities  Limited  underwrites,   distributes,   and  trades
international  securities,  including  Eurobonds,  commercial paper, and foreign
government  bonds.  J.P. Morgan & Co.  Incorporated  issues commercial paper and
long-term debt  securities.  Morgan  Guaranty and some of its  affiliates  issue
certificates of deposit and create bankers' acceptances.

    To the  extent  that  the Fund  invests  a  portion  of its  assets  in such
obligations,  it will not  invest  in  securities  issued or  created  by Morgan
affiliates.

    Certain  activities of Morgan  affiliates may affect the Fund's portfolio or
the markets for securities in which the Fund invests. In particular,  activities
of Morgan  affiliates  may affect the prices of securities  held by the Fund and
the  supply  of  issues  available  for  purchase  by the  Fund.  Where a Morgan
affiliate holds a large portion of a given issue,  the price at which that issue
is traded may  influence  the price of similar  securities  the Fund holds or is
considering purchasing.

    The Fund will not purchase securities  directly from Morgan affiliates,  and
the size of Morgan  affiliates'  holdings  may limit the  selection of available
securities in a particular maturity, yield, or price


STATEMENT OF ADDITIONAL INFORMATION                                            9


range.  The Fund will not execute any  transactions  with Morgan  affiliates and
will  use only  unaffiliated  broker-dealers.  In  addition,  the Fund  will not
purchase any securities of U.S.  government  agencies during the existence of an
underwriting or selling group of which a Morgan affiliate is a member, except to
the extent permitted by law.

    The Fund's  ability to engage in  transactions  with  Morgan  affiliates  is
restricted by the SEC and the Federal Reserve Board. In JPMIM's  opinion,  these
limitations  should not  significantly  impair the Fund's  ability to pursue its
investment objectives.  However, there may be circumstances in which the Fund is
disadvantaged  by  these  limitations  compared  to  other  funds  with  similar
investment objectives that are not subject to these limitations.

    In acting for its fiduciary  accounts,  including  the Fund,  JPMIM will not
discuss its  investment  decisions or positions with the personnel of any Morgan
affiliate.  JPMIM has informed the Fund that, in making investment decisions, it
will not obtain or use material, non-public information in the possession of any
division or department of JPMIM or other Morgan affiliates.

    The commercial  banking  divisions of Morgan Guaranty and its affiliates may
have deposit,  loan, and other commercial banking  relationships with issuers of
securities the Fund purchases, including loans that may be repaid in whole or in
part with the proceeds of  securities  purchased  by the Fund.  Except as may be
permitted  by  applicable  law,  the Fund will not  purchase  securities  in any
primary public offering when the prospectus  discloses that the proceeds will be
used to repay a loan from Morgan Guaranty. JPMIM will not cause the Fund to make
investments for the direct purpose of benefitting other commercial  interests of
Morgan affiliates at the Fund's expense.

VALUATION OF PORTFOLIO SECURITIES

    The Fund's net asset value per share  ("NAV") is  calculated as of the close
of business of the New York Stock  Exchange (the  "Exchange")  usually at 3 p.m.
Central  time each day the  Exchange  is open for  business.  The  Exchange  has
designated the following  holiday  closings for 1997: New Year's Day (observed),
Martin  Luther  King Jr.  Day,  Presidents'  Day,  Good  Friday,  Memorial  Day,
Independence  Day, Labor Day,  Thanksgiving  Day, and Christmas Day  (observed).
Although  the Fund  expects  the same  holiday  schedule  to be  observed in the
future, the Exchange may modify its holiday schedule at any time.

    Securities  are valued at market,  depending  upon the market or exchange on
which they trade. Price quotations for exchange-listed securities are taken from
the primary  exchanges on which these  securities  trade.  Securities  traded on
exchanges will be valued at their last sale prices. If no sale is reported,  the
mean  between  the  latest  bid and  asked  prices  is used.  Securities  traded
over-the-counter  will be valued at the mean  between  the  latest bid and asked
prices.  Fixed-income  securities  are  priced at  market  value on the basis of
market  quotations  supplied  by  independent   pricing  services.   Trading  of
securities  in foreign  markets may not take place on every day the  Exchange is
open,  and trading takes place in various  foreign  markets on days on which the
Exchange  and the Fund's  offices are not open and the Fund's net asset value is
not calculated. The Fund's net asset value may be significantly affected on days
when  shareholders  have no  access  to the Fund.  Securities  for which  market
quotations are not readily available, or which may change in value due to events
occurring  after their  primary  exchange  has closed for the day, are valued at
fair market value as  determined  in good faith under the direction of the Board
of Trustees.

    JPMIM  typically  completes  its  trading  on behalf of the Fund in  various
markets  before  the  Exchange  closes for the day,  and the value of  portfolio
securities is determined when the primary market for those securities closes for
the day. Foreign currency  exchange rates are also determined prior to the close
of the Exchange.  However,  if  extraordinary  events occur that are expected to
affect the value of a portfolio security after the close of the primary exchange
on which it is  traded,  the  security  will be valued at fair  market  value as
determined in good faith under the direction of the Board of Trustees.

PERFORMANCE

    The Fund's  yield and total  return may be quoted in  advertising  and sales
literature.  These figures,  as well as the Fund's share price,  will vary. Past
performance should not be considered an indication of future results.


10                                            AMERICAN CENTURY INVESTMENTS


    Yield quotations are based on the investment  income per share earned during
a  particular  30-day  period,  less  expenses  accrued  during the period  (net
investment  income),  and are  computed  by dividing  the Fund's net  investment
income  by its  share  price  on the last day of the  period,  according  to the
following formula:


    YIELD = 2 [(a - b + 1)(6)- 1]
               ------
                 cd


where a = dividends and interest earned during the period,  b = expenses accrued
for the period (net of  reimbursements),  c = the average daily number of shares
outstanding during the period that were entitled to receive  dividends,  and d =
the maximum offering price per share on the last day of the period.

   
    For the 30-day period ended June 30, 1997, the Fund's yield was 4.72%.
    

    Total returns quoted in advertising and sales literature reflect all aspects
of the Fund's return,  including the effect of reinvesting dividends and capital
gain distributions and any change in the Fund's NAV per share during the period.

    Average  annual total returns are  calculated by  determining  the growth or
decline  in value of a  hypothetical  historical  investment  in the Fund over a
stated period, and then calculating the annually compounded percentage rate that
would have  produced  the same  result if the rate of growth or decline in value
had been constant  throughout the period. For example, a cumulative total return
of 100% over 10 years would produce an average annual return of 7.18%,  which is
the steady annual rate that would result in 100% growth on a compounded basis in
10 years. While average annual total returns are a convenient means of comparing
investment alternatives, investors should realize that the Fund's performance is
not constant over time,  but changes from year to year,  and that average annual
total  returns  represent  averaged  figures as  opposed to actual  year-to-year
performance.

    In addition to average annual total returns,  the Fund may quote  unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment over a stated period. Average annual and cumulative total returns may
be quoted as a  percentage  or as a dollar  amount and may be  calculated  for a
single investment, a series of investments,  or a series of redemptions over any
time period.  Total  returns may be broken down into their  components of income
and capital  (including  capital gains and changes in share price) to illustrate
the relationship of these factors and their  contributions to total return.  The
Fund's one year,  three year,  five year and life of fund  average  annual total
return through June 30, 1997, are indicated in the following table:

                                      Average Annual Total Return
- --------------------------------------------------------------------
One Year                                        0.37%
Three Year                                      7.65%
Five Year                                       6.84%
Life of Fund                                    7.60%
- --------------------------------------------------------------------

    The Fund commenced  operations on January 7, 1992.  Performance  information
may be quoted numerically or in a table, graph, or similar illustration.

    The Fund's  performance may be compared with the performance of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may  include  comparisons  with funds that,  unlike  American
Century funds, are sold with a sales charge or deferred sales charge. Sources of
economic  data that may be used for such  comparisons  may include,  but are not
limited to, U.S. Treasury bill, note, and bond yields, money market fund yields,
U.S.  government debt and percentage held by foreigners,  the U.S. money supply,
net free reserves,  and yields on  current-coupon  Government  National Mortgage

market performance; and indexes and historical data supplied by major securities
brokerage or investment  advisory firms. The Fund may also utilize reprints from
newspapers  and magazines  furnished by third  parties to illustrate  historical
performance.

    The Fund's  shares are sold  without a sale charge (a load).  No-load  funds
offer an  advantage  to investors  when  compared to load funds with  comparable
investment objectives and strategies.

    The advisor may obtain ratings on the safety of Fund shares from one or more
rating  agencies  and may  publish  such  ratings  in  advertisements  and sales
literature.

TAXES

    The Fund will be treated as a separate  corporation  for federal  income tax
purposes  and intends to qualify  annually as a "regulated  investment  company"
under  Subchapter  M of the  Internal  Revenue  Code of 1986,  as  amended  (the
"Code"). By so qualifying, the Fund will not incur federal or state income taxes
on its net  investment  income or net  realized  capital  gains  distributed  to
shareholders.

    The Fund may be subject to a 4% excise tax on a portion of its undistributed
income. To avoid the tax, the Fund must distribute  annually at least 98% of its
ordinary  income (not taking into  account any capital  gains or losses) for the
calendar  year and at least 98% of its capital  gain net income for the 12-month
period ending on October 31st of the calendar year. Any dividend declared by the
Fund in October,  November,  or December of any year and payable to shareholders
of  record  on a  specified  date in such a month  shall be  deemed to have been
received by each shareholder on December 31st of such year and to have been paid
by the Fund not  later  than  December  31st of such  year,  provided  that such
dividend is actually paid by the Fund during January of the following year.

    The Fund's  transactions in foreign currencies,  forward contracts,  options
and  futures  contracts  (including  options and  futures  contracts  on foreign
currencies) will be subject to special  provisions of the Code that, among other
things, may affect the character of gains and losses realized by the Fund (i.e.,
may  affect  whether  gains or  losses  are  ordinary  or  capital),  accelerate
recognition  of  income  to  the  Fund,  defer  Fund  losses,   and  affect  the
determination of whether capital gains and losses are characterized as long-term
or short-term  capital gains or losses.  These rules could therefore  affect the
character, amount and timing of distributions to shareholders.  These provisions
also may require the Fund to mark to market  certain  types of the  positions in
its portfolio (i.e.,  treat them as if they were sold), which may cause the Fund
to recognize income without  receiving cash with which to make  distributions in
amounts  necessary  to satisfy  the 90% and 98%  distribution  requirements  for
relief from income and excise  taxes,  respectively.  The Fund will  monitor its
transactions   and  may  make  such  tax  elections  as  Fund  management  deems
appropriate  with respect to foreign  currency,  options,  futures  contracts or
forward contracts. The Fund's status as a regulated investment company may limit
its  transactions  involving  foreign  currency,  futures,  options  and forward
contracts.

    Under the Code,  gains or losses  attributable  to  fluctuations in exchange
rates that occur between the time the Fund accrues  income or other  receivables
or accrues expenses or other  liabilities  denominated in a foreign currency and
the time the Fund actually  collects such  receivables or pays such  liabilities
generally  are treated as ordinary  income or loss.  Similarly,  in disposing of
debt securities  denominated in foreign  currencies,  certain  forward  currency
contracts, or other instruments, gains or losses attributable to fluctuations in
the value of a foreign  currency  between the date the  security,  contract,  or
other  instrument  is acquired  and the date it is disposed of are also  usually
treated as ordinary income or loss.  Under Section 988 of the Code,  these gains
or losses may increase or decrease the amount of the Fund's  investment  company
taxable income distributed to shareholders as ordinary income.

    Earnings derived by the Fund from sources outside the U.S. may be subject to
non-U.S.  withholding  and possibly  other  taxes.  Such taxes may be reduced or
eliminated under the terms of a U.S. income tax treaty,  and the Fund intends to
undertake any proce-


12                                            AMERICAN CENTURY INVESTMENTS


dural steps required to claim the benefits of such a treaty. With respect to any
non-U.S.  taxes  actually  paid by the  Fund,  if more  than 50% in value of the
Fund's total assets at the close of any taxable year  consists of  securities of
foreign  corporations,  the Fund will  elect to treat any  non-U.S.  income  and
similar taxes it pays as though the taxes were paid by its shareholders.

    Some of the debt  securities that may be acquired by the Fund may be treated
as debt securities originally issued at a discount. Generally, the amount of the
original issue  discount (OID) is treated as interest  income and is included in
income over the term of the debt security even though  payment of that amount is
not received until a later time, usually when the debt security matures.

    Some of the debt  securities may be purchased by the Fund at a discount that
exceeds the  original  issue  discount  on such debt  securities,  if any.  This
additional  discount represents market discount for federal income tax purposes.
The gain realized on the  disposition of any taxable debt security having market
discount will be treated as ordinary income to the extent it does not exceed the
accrued  market  discount on such debt security if such market  discount was not
previously included in taxable income.  Generally,  market discount accrues on a
daily  basis for each day the debt  security  is held by the Fund at a  constant
rate over the time remaining to the debt security's maturity or, at the election
of the Fund,  at a  constant  yield to  maturity  that takes  into  account  the
semiannual compounding of interest.

    Exchange control  regulations  that may restrict  repatriation of investment
income,  capital,  or the proceeds of securities sales by foreign  investors may
limit the Fund's ability to make sufficient distributions to satisfy the 90% and
excise tax distribution requirements.

TAXATION OF U.S. SHAREHOLDERS

    Upon  redeeming,  selling,  or exchanging  shares of the Fund, a shareholder
will  realize  a  taxable  gain or loss  depending  upon his or her basis in the
shares liquidated. The gain or loss generally will be a capital gain or loss, if
the shares are capital assets in the shareholder's  hands, and will be long-term
or short-term  depending on the length of time the shares were held.  However, a
loss  recognized by a shareholder in the  disposition of shares on which capital
gain dividends were paid (or deemed paid) before the shareholder had held his or
her shares for more than six months would be treated as a long-term capital loss
for tax purposes.

    A gain realized on the redemption,  sale, or exchange of shares would not be
affected by the reacquisition of shares. A loss realized on a redemption,  sale,
or exchange of shares would be disallowed to the extent that the shares disposed
of were replaced  (whether  through  reinvestment of distributions or otherwise)
within a period of 61 days beginning 30 days before and ending 30 days after the
date on which the shares were disposed.  Under such circumstances,  the basis of
the shares acquired would be adjusted to reflect the disallowed loss.

TAXATION OF NON-U.S. SHAREHOLDERS

    U.S.  taxation of a shareholder  who is a  non-resident  alien or a non-U.S.
corporation,  partnership,  trust,  or estate  depends on whether  the  payments
received from a Fund are  "effectively  connected" with a U.S. trade or business
carried on by such a shareholder.  Ordinarily,  income from the Fund will not be
treated as "effectively connected."

    If the payments received from the Fund are effectively connected with a U.S.
trade or business of the shareholder,  then all  distributions of net investment
income and net capital gains of the Fund and gains realized upon the redemption,
exchange, or other taxable disposition of shares will be subject to U.S. federal
income tax at the graduated rates  applicable to U.S.  citizens,  residents,  or
domestic  entities,  although  the tax may be  eliminated  under the terms of an
applicable U.S. income tax treaty.  Non-U.S.  corporate shareholders also may be
subject to a branch profits tax with respect to payments from the Fund.

    If the  shareholder  is not  engaged  in a U.S.  trade or  business,  or the
payments  received from the Fund are not effectively  connected with the conduct
of such a trade or business,  the shareholder  will generally be subject to U.S.
tax  withholding  at the rate of 30% (or a lower rate under an  applicable  U.S.
income tax treaty) on  distributions  of net investment  income and net realized
short-term capital received.  Non-U.S.  shareholders not engaged in a U.S. trade
or business, or


STATEMENT OF ADDITIONAL INFORMATION                                13


having no effectively  connected income,  may also be subject to U.S. tax at the
rate of 30% (or a lower treaty rate) on additional  distributions resulting from
the Fund's election to treat any non-U.S. taxes it pays as though the taxes were
paid by its shareholders.

    Distributions   of  net  realized   long-term   capital  gains  to  non-U.S.
shareholders and any capital gains realized by them upon the redemption or other
taxable  disposition of shares generally will not be subject to U.S. tax. In the
case of individuals  and other  non-exempt,  non-U.S.  shareholders  who fail to
furnish the Fund with required certifications  regarding their foreign status on
IRS Form W-8 or an  appropriate  substitute,  the Fund may be required to impose
backup  withholding  of  U.S.  tax at the  rate of 31% on  distributions  of net
realized capital gains and proceeds of redemptions and exchanges.

    The  information  above is only a summary of some of the tax  considerations
affecting  the Fund and its  shareholders;  no attempt  has been made to discuss
individual tax consequences.  The Fund and the Fund's  distributions may also be
subject to state,  local,  or foreign taxes. A prospective  investor may wish to
consult a tax advisor to  determine  whether  the Fund is a suitable  investment
based on his or her tax situation.

ABOUT THE TRUST

   
    American  Century  International  Bond Funds (the  "Trust") is a  registered
open-end  management  investment  company that was organized as a  Massachusetts
business  trust on August  28,  1991.  The Trust was  formerly  known as "Benham
International  Funds."  American  Century  --  Benham  International  Bond  Fund
(formerly known as American  Century--Benham  European  Government Bond Fund and
Benham European Government Bond Fund) is currently the sole series of the Trust.
The Board of Trustees may create additional series from time to time.
    

    The Declaration of Trust permits the Board of Trustees to issue an unlimited
number of full and fractional  shares of beneficial  interest without par value,
which may be  issued  in  series  (funds).  Shares  issued  are  fully  paid and
nonassessable and have no preemptive, conversion, or similar rights.

    Shares of the Fund have equal voting rights, provided that each series votes
separately  on  matters  affecting  only  that  series.  Voting  rights  are not
cumulative.  In the election of Trustees, each nominee may receive only one vote
from  each  shareholder,  and,  because  the  election  requires  only a  simple
majority, more than 50% of the shares voting in an election can elect all of the
Trustees.

    Each shareholder has rights to dividends and  distributions  declared by the
Fund and to the net  assets  of the Fund  upon its  liquidation  or  dissolution
proportionate to his or her share ownership interest in the Fund.

    Shareholders  of  a  Massachusetts   business  trust  could,  under  certain
circumstances,  be held  personally  liable  as  partners  for its  obligations.
However,  the Declaration of Trust contains an express disclaimer of shareholder
liability for acts or  obligations of the Trust.  The  Declaration of Trust also
provides for  indemnification  and  reimbursement of expenses of any shareholder
held personally  liable for  obligations of the Trust.  The Declaration of Trust
provides that the Trust will, upon request, assume the defense of any claim made
against any  shareholder  for any act or obligation of the Trust and satisfy any
judgment  thereon.  The Declaration of Trust further provides that the Trust may
maintain appropriate insurance (for example,  fidelity,  bonding, and errors and
omissions  insurance)  for  the  protection  of  the  Trust,  its  shareholders,
Trustees,  officers,  employees,  and  agents to cover  possible  tort and other
liabilities.  Thus,  the risk of a  shareholder  incurring  financial  loss as a
result of  shareholder  liability  is  limited  to  circumstances  in which both
inadequate insurance exists and the Trust is unable to meet its obligations.

    CUSTODIAN BANKS:  State Street Bank and Trust Company,  225 Franklin Street,
Boston, Massachusetts,  02101 and Commerce Bank, N.A., 1000 Walnut, Kansas City,
Missouri  64106 serve as custodians of the Fund's assets.  Services  provided by
the custodian  bank include (i) settling  portfolio  purchases  and sales,  (ii)
reporting failed trades,  (iii) identifying and collecting portfolio income, and
(iv)  providing  safekeeping  of  securities.  The  custodian  takes  no part in
determining the Fund's  investment  policies or in determining  which securities
are sold or purchased by the Fund.

    INDEPENDENT AUDITORS: KPMG Peat Marwick LLP, 1000 Walnut, Suite 1600, Kansas
City, Missouri 64106, serves as the Trust's independent auditors audits the

annual financial statements.

    For the current fiscal year,  which started on January 1, 1997, the Trustees
of the Fund have selected Coopers & Lybrand LLP to serve as independent auditors
of the Fund.  The address of Coopers & Lybrand LLP is City Center  Square,  1100
Main Street, Suite 900, Kansas City, Missouri 64105-2140.

   
MULTIPLE CLASS STRUCTURE

    The  Fund's  Board of  Trustees  has  adopted  a  multiple  class  plan (the
"Multiclass  Plan") pursuant to Rule 18f-3 adopted by the SEC.  Pursuant to such
plan, the funds may issue up to three classes of funds:  an Investor  Class,  an
Advisor Class and an Institutional Class. Not all funds offer all three classes.

    The Investor Class is made available to investors directly by the investment
manager  through  its  affiliated  broker-dealer,  American  Century  Investment
Services,  Inc.,  for a  single  unified  management  fee,  without  any load or
commission.  The  Institutional  and  Advisor  Classes  are  made  available  to
institutional  shareholders  or  through  financial  intermediaries  that do not
require  the same level of  shareholder  and  administrative  services  from the
Manager as  Investor  Class  shareholders.  As a result,  the Manager is able to
charge  these  classes  a lower  unified  management  fee.  In  addition  to the
management  fee,  however,   Advisor  Class  shares  are  subject  to  a  Master
Distribution and Shareholder  Services Plan (described below). The plan has been
adopted by the Fund's Board of Trustees and initial  shareholder  in  accordance
with Rule 12b-1 adopted by the SEC under the Investment Company Act.

RULE 12B-1

    Rule 12b-1 permits an investment company to pay expenses associated with the
distribution  of its shares in accordance  with a plan adopted by the investment
company's Board of Trustees and approved by its  shareholders.  Pursuant to such
rule, the Board of Trustees and initial  shareholder of the Fund's Advisor Class
has approved and entered into a Master  Distribution  and  Shareholder  Services
Plan,  with respect to the Advisor Class (the "Plan").  The Master  Distribution
and Shareholder Services Plan is described below.

    In adopting  the Plan,  the Board of Trustees  [including a majority who are
not  "interested  persons"  of the funds (as defined in the  Investment  Company
Act),  hereinafter  referred to as the "independent  trustees"]  determined that
there was a reasonable  likelihood  that the Plan would benefit the Fund and the
shareholders of the affected  class.  Pursuant to Rule 12b-1,  information  with
respect to revenues  and  expenses  under the Plan is  presented to the Board of
Trustees quarterly for its consideration in connection with its deliberations as
to the continuance of the Plan.  Continuance of the Plan must be approved by the
Board of Trustees  (including a majority of the independent  trustees) annually.
The Plan may be amended by a vote of the Board of Trustees (including a majority
of the  independent  trustees),  except  that  the Plan  may not be  amended  to
materially  increase the amount to be spent for  distribution  without  majority
approval  of  the  shareholders  of  the  affected  class.  The  Plan  terminate
automatically in the event of an assignment and may be terminated upon a vote of
a  majority  of  the  independent  trustees  or by  vote  of a  majority  of the
outstanding voting securities of the affected class.

    All fees paid under the plans will be made in accordance  with Section 26 of
the Rules of Fair Practice of the National Association of Securities Dealers.

MASTER DISTRIBUTION AND SHAREHOLDER SERVICES PLAN

    As described in the Prospectuses, the Fund's Advisor Class of shares is made
available to participants in employer-sponsored  retirement or savings plans and
to  persons  purchasing  through  financial   intermediaries,   such  as  banks,
broker-dealers  and insurance  companies.  The Distributor enters into contracts
with various  banks,  broker-dealers,  insurance  companies and other  financial
intermediaries  with respect to the sale of the funds'  shares and/or the use of
the Fund's shares in various  investment  products or in connection with various
financial services.

    Certain  recordkeeping and administrative  services that are provided by the
Fund's transfer agent for the Investor Class  shareholders may be performed by a
plan sponsor (or its agents) or by a financial  intermediary for shareholders in
the Advisor Class. In addition to such services, the financial intermediaries


STATEMENT OF ADDITIONAL INFORMATION                                   15


provide various distribution services.

    To enable  the Fund's  shares to be made  available  through  such plans and
financial  intermediaries,  and to compensate them for such services, the funds'
investment  manager  has  reduced  its  management  fee by 0.25% per annum  with
respect to the Advisor Class shares and the Fund's Board of Trustees has adopted
the Plan.  Pursuant to such Plan, the Advisor Class shares pay the Distributor a
fee of 0.50%  annually  of the  aggregate  average  daily  assets of the  Fund's
Advisor  Class  shares,  0.25% of which is paid  for  Shareholder  Services  (as
described above) and 0.25% of which is paid for distribution services.

    Distribution  services  include any activity  undertaken or expense incurred
that is primarily intended to result in the sale of Advisor Class shares,  which
services  may  include  but  are  not  limited  to,  (a) the  payment  of  sales
commission,   ongoing  commissions  and  other  payments  to  brokers,  dealers,
financial  institutions  or others who sell  Advisor  Class  shares  pursuant to
Selling  Agreements;  (b)  compensation to registered  representatives  or other
employees of  Distributor  who engage in or support  distribution  of the Fund's
Advisor Class shares; (c) compensation to, and expenses  (including overhead and
telephone  expenses)  of,   Distributor;   (d)  the  printing  of  prospectuses,
statements  of  additional  information  and  reports  for other  than  existing
shareholders; (e) the preparation, printing and distribution of sales literature
and advertising  materials  provided to the Fund's  shareholders and prospective
shareholders;  (f)  receiving  and  answering  correspondence  from  prospective
shareholders,  including  distributing  prospectuses,  statements  of additional
information,  and shareholder reports; (g) the providing of facilities to answer
questions  from  prospective  investors  about Fund shares;  (h) complying  with
federal and state  securities  laws  pertaining to the sale of fund shares;  (i)
assisting  investors in completing  application forms and selecting dividend and
other  account  options;  (j) the  providing of other  reasonable  assistance in
connection  with  the  distribution  of  Fund  shares;  (k) the  organizing  and
conducting  of  sales  seminars  and  payments  in  the  form  of  transactional
compensation  or promotional  incentives;  (l) profit on the foregoing;  (m) the
payment of "service fees" for the provision of personal,  continuing services to
investors,  as  contemplated  by the Rules of Fair  Practice of the NASD and (n)
such other distribution and services activities as the Manager determines may be
paid for by the Fund  pursuant to the terms of this  Agreement and in accordance
with Rule 12b-1 of the Investment Company Act.

fiscal year ended  December 31, 1996, as well as the  compensation  received for
serving as Director or Trustee of all other funds advised by the Manager.

MANAGEMENT

    The Fund has an  investment  management  agreement  with the  Manager  dated
August 1, 1997.  This agreement was approved by the  shareholders of the Fund on
July 30, 1997.

    For the services  provided to the Fund,  the Manager  receives a monthly fee
based on a percentage of the average net assets of the Fund.  The annual rate at
which this fee is assessed is determined monthly in a two-step process: First, a
fee rate schedule is applied to the assets of all of the funds of its investment
category  managed by the Manager  (the  "Investment  Category  Fee").  The three
investment  categories  are Money  Market  Funds,  Bond Funds and Equity  Funds.
Second,  a  separate  fee rate  schedule  is applied to the assets of all of the
funds managed by the Manager (the "Complex  Fee").  The Investment  Category Fee
and the  Complex Fee are then added to  determine  the  unified  management  fee
payable by the Fund to the Manager.

    The  schedule  by which the  Investment  Category  Fee is  determined  is as
follows:

Category Assets                                       Fee Rate
- -------------------------------------------------------------------
First $1 billion                                      0.6100%
Next $1 billion                                       0.5580%
Next $3 billion                                       0.5280%
Next $5 billion                                       0.5080%
Next $15 billion                                      0.4950%
Next $25 billion                                      0.4930%
Thereafter                                            0.4925%
- -------------------------------------------------------------------


    The Complex Fee Schedule is as follows:

Complex Assets                                        Fee Rate
- -------------------------------------------------------------------
First $2.5 billion                                    0.3100%
Next $7.5 billion                                     0.3000%
Next $15.0 billion                                    0.2985%
Next $25.0 billion                                    0.2970%
Next $50.0 billion                                    0.2960%
Next $100.0 billion                                   0.2950%
Next $100.0 billion                                   0.2940%
Next $200.0 billion                                   0.2930%
Next $250.0 billion                                   0.2920%
Next $500.0 billion                                   0.2910%
Thereafter                                            0.2900%
- -------------------------------------------------------------------

   
    The Complex Fee schedule for the Institutional  Class is lower by 0.2500% at
each graduated  step. For example,  if the Investor Class Complex Fee is 0.3000%
for the first $2 billion,  the  Advisor  Class  Complex Fee is 0.0500%  (0.3000%
minus 0.2500%) for the first $2 billion.
    

    On the first  business day of each month,  the Fund pays a management fee to
the  Manager  for the  previous  month at the  specified  rate.  The fee for the
previous month is calculated by  multiplying  the applicable fee for the Fund by
the  aggregate  average  daily closing value of the Fund's net assets during the
previous  month by a fraction,  the  numerator of which is the number of days in
the previous month and the denominator of which is 365 (366 in leap years).

    The management  agreement  shall continue in effect until the earlier of the
expiration  of two  years  from the date of its  execution  or until  the  first
meeting of  shareholders  following such execution and for as long thereafter as
its  continuance  is  specifically  approved at least annually by (1) the Fund's
Board of Trustees, or by the vote of a majority of outstanding votes (as defined
in the Investment Company Act) and (2) by the vote of a majority of the Trustees
of the Fund who are not parties to the  agreement or  interested  persons of the
Manager,  cast in person at a meeting  called for the  purpose of voting on such
approval.

    The  management  agreement  provides  that it may be  terminated at any time
without payment of any penalty by the Fund's Board of Trustees,  or by a vote of
a  majority  of the  Fund's  shareholders,  on 60 days'  written  notice  to the
Manager, and that it shall be automatically terminated if it is assigned.

    The  management  agreement  provides that the Manager shall not be liable to
the Fund or its  shareholders for anything other than willful  misfeasance,  bad
faith, gross negligence or reckless disregard of its obligations and duties.

    The  management  agreement  also provides that the Manager and its officers,
Trustees and employees may engage in other  business,  devote time and attention
to any other  business  whether of a similar or  dissimilar  nature,  and render
services to others.

    Certain  investments  may be  appropriate  for the Fund  and also for  other
clients advised by the


18                                            AMERICAN CENTURY INVESTMENTS


Manager.  Investment  decisions  for the Fund and other  clients are made with a
view to achieving their respective  investment objectives after consideration of
such factors as their current holdings, availability of cash for investment, and
the size of their investment  generally.  A particular security may be bought or
sold for only one client or series,  or in  different  amounts and at  different
times  for more than one but less  than all  clients  or  series.  In  addition,
purchases  or sales of the same  security may be made for two or more clients or
series on the same date. Such  transactions will be allocated among clients in a
manner  believed  by the  Manager to be  equitable  to each.  In some cases this
procedure  could have an adverse effect on the price or amount of the securities
purchased or sold by the Fund.

    The Manager may aggregate purchase and sale orders of the Fund with purchase
and sale  orders  of its  other  clients  when the  Manager  believes  that such
aggregation  provides  the best  execution  for the Fund.  The  Fund's  Board of
Trustees has approved the policy of the Manager with respect to the  aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the Fund  participates  at the average share price for all  transactions in that
security on a given day and share  transaction  costs on a pro rata  basis.  The
Manager will not aggregate portfolio transactions of the Fund unless it believes
such aggregation is consistent with its duty to seek best execution on behalf of
the Fund and the terms of the  management  agreement.  The  Manager  receives no
additional compensation or remuneration as a result of such aggregation.

    In addition to managing  the Fund,  the Manager  also acts as an  investment
advisor to 12 institutional  accounts and to the following registered investment
companies:  American Century Mutual Funds,  Inc.,  American Century World Mutual
Funds, Inc., American Century Premium Reserves,  Inc., American Century Variable
Portfolios,  Inc., American Century Capital  Portfolios,  Inc., American Century
Strategic Asset Allocations,  Inc.,  American Century Municipal Trust,  American
Century  Government Income Trust,  American Century  Investment Trust,  American
Century  Target  Maturities  Trust,  American  Century  California  Tax-Free and
Municipal Funds and American Century Quantitative Equity Funds.

    Prior to  August  1,  1997,  Benham  Management  Corporation  served  as the
investment  advisor to the Fund.  Benham  Management  Corporation  is,  like the
Manager, wholly-owned by ACC.

   
    For the fiscal years ended December 31, 1996,  1995, and 1994, the Fund paid
investment advisory fees as listed in the table below.
    

                                   Investment Advisory Fees
- --------------------------------------------------------------
    1996                               $1,060,306
    1995                               $1,017,677
    1994                               $1,124,210
- --------------------------------------------------------------

    The investment  management  agreement provides that the Manager may delegate
certain responsibilities under the agreement to a subadvisor.  Currently,  JPMIM
serves as  subadvisor  to the Fund under a  subadvisory  agreement  between  the
Manager and JPMIM dated  August 1, 1997,  that was approved by  shareholders  on
July 30,  1997.  This  superseded  subadvisory  agreements  dated  June 1, 1995,
December 31, 1991, and June 1, 1994. The subadvisory  agreement continues for an
initial   period  of  two  years  and  thereafter  so  long  as  continuance  is
specifically  approved  by vote of a majority of the Fund's  outstanding  voting
securities or by vote of a majority of the Fund's Trustees, including a majority
of those  Trustees  who are  neither  parties to the  agreement  nor  interested
persons of any such party, cast in person at a meeting called for the purpose of
voting on such  approval.  The  subadvisory  agreement is subject to termination
without  penalty  on 60  days'  written  notice  by the  Manager,  the  Board of
Trustees,  or a majority of the Fund's  outstanding shares or 12 months' written
notice  by  JPMIM  and  will  terminate  automatically  in the  event of (i) its
assignment or (ii) termination of the investment  advisory agreement between the
Fund and the Manager.

    The subadvisory agreement provides that JPMIM will make investment decisions
for the Fund in accordance with the Fund's investment objective,  policies,  and
restrictions, and whatever additional written guidelines it may receive from the
Manager from time to time. For these services,  the Manager pays JPMIM a monthly
fee at an annual rate of .20% of the Fund's  average daily net assets up to $200
million; and .15% of average daily net assets over $200 million.  Under the 1991
subadvisory agreement, the Manager paid


STATEMENT OF ADDITIONAL INFORMATION                                   19


JPMIM a monthly fee at an annual rate of .25% of average  daily net assets up to
$200  million,  and .05% of average  daily net assets in excess of $200 million,
with a minimum annual fee of $250,000.

    For the fiscal years ended  December 31,  1996,  1995 and 1994,  the Manager
paid JPMIM subadvisory fees as listed in the following table:

TRANSFER AND ADMINISTRATIVE SERVICES

    American  Century  Services  Corporation,  4500 Main  Street,  Kansas  City,
Missouri  64111,  acts as transfer agent and dividend paying agent for the Fund.
It provides physical  facilities,  including  computer hardware and software and
personnel, for the day-to-day administration of the Fund and of the Manager. The
Manager pays American Century Services Corporation for such services.

    Prior to August 1, 1997, the Fund paid American Century Services Corporation
directly for its services as transfer agent and administrative services agent.

    For the fiscal years ended  December 31, 1996,  and 1995,  the fees paid for
administrative  services  and for  transfer  agent  services  are  listed in the
following table:

DISTRIBUTION OF FUND SHARES

    The Fund's shares are distributed by American Century  Investment  Services,
Inc. (the  "Distributor"),  a registered  broker-dealer  and an affiliate of the
Manager. The Manager pays all expenses for promoting and distributing the Fund's
shares.  The Fund does not pay any  commissions or other fees to the Distributor
or to any other  broker-dealers  or financial  intermediaries in connection with
the distribution of Fund shares.

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

    The Fund's shares are  continuously  offered at NAV. Share  certificates are
issued  (without  charge) only when requested in writing.  Certificates  are not
issued for fractional shares. Dividend and voting rights are not affected by the
issuance of certificates.

    American  Century may reject or limit the amount of an investment to prevent
any one shareholder or affiliated group from controlling the Trust or one of its
series; to avoid jeopardizing a series' tax status; or whenever, in management's
opinion,  such  rejection  is in the Trust's or a series' best  interest.  As of
April 7, 1997,  Charles  Schwab & Co., 101  Montgomery  Street,  San  Francisco,
California 94104, was the record holder of 34% of the outstanding  shares of the
Fund with  6,986,691.849  shares.  As of that date, no other shareholder was the
record  holder or  beneficial  owner of 5% or more of the  Fund's  total  shares
outstanding.

    ACS charges  neither fees nor  commissions  on the purchase and sale of fund
shares.  However,  ACS may  charge  fees for  special  services  requested  by a
shareholder or necessitated by acts or omissions of a shareholder.  For example,
ACS may charge a fee for processing dishonored investment checks or stop-payment
requests. See the Investor Services Guide for more information.

SECURITIES RATINGS

    Securities  rating  descriptions  provided  under this heading are excerpted
from  publications  of Moody's  Investors  Service,  Inc.  and Standard & Poor's
Corporation.

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S MUNICIPAL BOND RATINGS:

    AAA:  Bonds that are rated "Aaa" are judged to be of the best quality.  They
carry the smallest degree of


20                                         AMERICAN CENTURY INVESTMENTS


investment risk and are generally  referred to as "gilt edge." Interest payments
are  protected  by a large or  exceptionally  stable  margin,  and  principal is
secure. While the various protective elements are likely to change, such changes
as can be  visualized  are most  unlikely  to impair  the  fundamentally  strong
position of such issues.

    AA:  Bonds  that are  rated  "Aa" are  judged to be of high  quality  by all
standards. Together with the Aaa group, they constitute what are generally known
as high-grade bonds. They are rated lower than the best bonds because margins of
protection  may  not  be as  large  as in  Aaa  securities,  or  fluctuation  of
protective elements may be of greater amplitude,  or there may be other elements
present that make long-term risks appear somewhat larger than in Aaa securities.

    A: Bonds that are rated "A" possess many favorable investment attributes and
are to be considered as upper medium-grade obligations.  Factors giving security
to principal and interest are considered  adequate,  but elements may be present
that suggest a susceptibility to impairment sometime in the future.

    BAA:  Bonds that are rated "Baa" are  considered  medium-grade  obligations,
i.e., they are neither highly  protected nor poorly secured.  Interest  payments
and principal  security appear adequate for the present,  but certain protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics and, in
fact, have speculative characteristics as well.

    BA: Bonds that are rated "Ba" are judged to have speculative elements; their
future cannot be considered  as well assured.  Often the  protection of interest
and  principal  payments may be very  moderate and thereby not well  safeguarded
during  both  good  and  bad  times  in  the  future.  Uncertainty  of  position
characterizes bonds in this class.

    B: Bonds that are rated "B" generally  lack  characteristics  of a desirable
investment.  Assurance of interest and principal  payments or of  maintenance of
other terms of the contract over any long period of time may be limited.

    CAA: Bonds that are rated "Caa" are of poor standing.  Such issues may be in
default, or there may be elements of danger present with respect to principal or
interest.

    CA: Bonds that are rated "Ca" represent  obligations that are speculative to
a  high  degree.  Such  issues  are  often  in  default  or  have  other  marked
shortcomings.

    C: Bonds that are rated "C" are the lowest-rated  class of bonds, and issues
so rated can be regarded as having  extremely  poor  prospects of ever attaining
any real investment standing.

    Note:  Moody's may apply the numerical  modifier "1" for municipally  backed
bonds and modifiers "1," "2," and "3" for corporate-backed  municipal bonds. The
modifier "1" indicates  that the security ranks in the higher end of its generic
rating  category;  the  modifier  "2"  indicates  a mid-range  ranking,  and the
modifier  "3"  indicates  that the issue  ranks in the lower end of its  generic
rating category.

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S RATINGS
OF NOTES AND VARIABLE-RATE DEMAND OBLIGATIONS:

    Moody's  ratings  for  state  and  municipal   short-term   obligations  are
designated   Moody's  Investment  Grade  or  MIG.  Such  ratings  recognize  the
differences between short-term credit and long-term risk.  Short-term ratings on
issues   with   demand   features   (variable-rate   demand   obligations)   are
differentiated by the use of the VMIG symbol to reflect such  characteristics as
payment upon periodic  demand rather than on fixed  maturity  dates and payments
relying on external liquidity.

    MIG  1/VMIG  1:  This  designation  denotes  best  quality.  There is strong
protection present through  established cash flows,  superior liquidity support,
or demonstrated broad-based access to the market for refinancing.

    MIG 2/VMIG 2: This denotes high quality.  Margins of  protection  are ample,
although not as large as in the preceding group.

DESCRIPTION OF MOODY'S INVESTORS SERVICE, INC.'S
TAX-EXEMPT COMMERCIAL PAPER RATINGS:

    Moody's  commercial  paper ratings are opinions of the ability of issuers to
punctually repay those promissory obligations that have an original maturity not
exceeding nine months. Moody's makes no representation that such obligations are
exempt from registration under the Securities Act of 1933, nor does it represent
that any specific note is a valid obligation of


STATEMENT OF ADDITIONAL INFORMATION                                   21


a rated issuer or issued in conformity  with any  applicable  law. The following
designations, all judged to be investment grade, indicate the relative repayment
ability of rated issuers of securities in which the Funds may invest.

    PRIME  1:  Issuers  rated  "Prime  1" (or  supporting  institutions)  have a
superior ability for repayment of senior short-term promissory obligations.

    PRIME 2: Issuers rated "Prime 2" (or supporting  institutions) have a strong
ability for repayment of senior short-term promissory obligations.

DESCRIPTION OF STANDARD & POOR'S CORPORATION'S RATINGS FOR MUNICIPAL BONDS:

INVESTMENT GRADE

    AAA: Debt rated "AAA" has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

    AA: Debt rated "AA" has a very strong capacity to pay interest and repay
principal and differs from the highest-rated issues only in a small degree.

    A: Debt rated "A" has a strong capacity to pay interest and repay principal,
although it is somewhat more  susceptible  to the adverse  effects of changes in
circumstances and economic conditions than debt in higher-rated categories.

    BBB:  Debt rated "BBB" is  regarded  as having an  adequate  capacity to pay
interest and repay principal.  Whereas it normally exhibits adequate  protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
debt in this category than in higher-rated categories.

SPECULATIVE

    BB, B,  CCC,  CC:  Debt  rated in these  categories  is  regarded  as having
predominantly  speculative  characteristics  with  respect  to  capacity  to pay
interest and repay principal.  While such debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions.

    BB: Debt rated "BB" has less near-term  vulnerability  to default than other
speculative issues. However, it faces major ongoing uncertainties or exposure to
adverse  business,   financial,  or  economic  conditions  that  could  lead  to
inadequate  capacity to meet timely  interest and principal  payments.  The "BB"
rating  category  is also  used for debt  subordinated  to  senior  debt that is
assigned an actual or implied "BBB-" rating.

    B: Debt rated "B" has a greater  vulnerability  to default but currently has
the  capacity  to meet  interest  payments  and  principal  repayments.  Adverse
business,  financial,  or economic  conditions  will likely  impair  capacity or
willingness to pay interest and repay principal. The "B" rating category is also
used for debt  subordinated to senior debt that is assigned an actual or implied
"BB" or "BB-" rating.

    CCC: Debt rated "CCC" has a currently identifiable  vulnerability to default
and is dependent upon favorable business,  financial, and economic conditions to
meet timely  payment of interest  and  repayment of  principal.  In the event of
adverse business,  financial,  or economic conditions,  it is not likely to have
the capacity to pay interest and repay  principal.  The "CCC" rating category is
also used for debt  subordinated  to senior  debt that is  assigned an actual or
implied "B" or "B-" rating.

    CC: The rating "CC" typically is applied to debt subordinated to senior debt
that is assigned an actual or implied "CCC" debt rating.

    C: The "C" rating is typically  applied to debt  subordinated to senior debt
that is assigned an actual or implied "CCC-" debt rating.  The "C" rating may be
used to cover a situation where a bankruptcy  petition has been filed,  but debt
service payments are continued.

    CI: The "CI"  rating is  reserved  for income  bonds on which no interest is
being paid.

    D: Debt rated "D" is in default, and payment of interest and/or repayment of
principal is in arrears.

    PLUS (+) OR MINUS (-): The ratings from "AA" to "CCC" may be modified by the
addition  of a plus or minus  sign to show  relative  standing  within the major
rating categories.

DESCRIPTION  OF STANDARD & POOR'S  CORPORATION'S  RATINGS FOR  INVESTMENT  GRADE
MUNICIPAL NOTES AND SHORT-TERM DEMAND OBLIGATIONS:

    SP-1: Issues carrying this designation have a very strong or strong capacity
to pay principal and inter-


22                                              AMERICAN CENTURY INVESTMENTS


est. Those issues determined to possess overwhelming safety characteristics will
be given a plus (+) designation.

    SP-2:  Issues carrying this designation have a satisfactory  capacity to pay
principal and interest.

DESCRIPTION OF STANDARD & POOR'S  CORPORATION'S  RATINGS FOR DEMAND  OBLIGATIONS
AND TAX-EXEMPT COMMERCIAL PAPER:

    A Standard & Poor's  commercial paper rating is a current  assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days. The two rating categories for securities in which the Funds may invest
are as follows:

    A-1: This highest  category  indicates  that the degree of safety  regarding
timely payment is strong.  Those issues  determined to possess  extremely strong
safety characteristics are denoted with a plus (+) designation.

    A-2:  Capacity  for  timely  payment  on  issues  with this  designation  is
satisfactory.  However,  the  relative  degree  of  safety is not as high as for
issues designated "A-1."

         to and approval in writing by the Trust,  which  approval  shall not be
         unreasonably  withheld.  Such  records  may not be  withheld  when  the
         Sub-Advisor  may be exposed to civil or criminal  contempt  proceedings
         for failure to comply,  when  requested to divulge such  information by
         duly  constituted  authorities,  or when so requested by the Trust.  In
         providing  those services,  the  Sub-Advisor  will supervise the Fund's
         investments and conduct a continual  program of investment,  evaluation
         and, if appropriate,  sale and  reinvestment  of the Fund's assets.  In
         addition,  the Sub-Advisor will furnish the Trust or ACIM with whatever
         information,   including  statistical  data,  the  Trust  or  ACIM  may
         reasonably  request with respect to the  instruments  that the Fund may
         hold or contemplate purchasing.

III.     BROKERAGE

         A.       Securities.   In  executing  transactions  for  the  Fund  and
                  selecting  brokers or dealers,  the  Sub-Advisor  will use its
                  best  efforts  to  obtain  the best net  price  and  execution
                  available  and shall  execute or direct the  execution  of all
                  such  transactions  as  permitted  by law and in a manner that
                  best suits the interest of the Fund and its  shareholders.  In
                  assessing the best net price and  execution  available for any
                  Fund transaction, the Sub-Advisor will consider all factors it
                  deems relevant  including,  but not limited to, breadth of the
                  market  in  the  security,  the  price  of the  security,  the
                  financial condition and execution  capability of the broker or
                  dealer  and  the  reasonableness  of any  commission  for  the
                  specific  transaction and on a continuing  basis..  Consistent
                  with this obligation,  when the execution and price offered by
                  two or more brokers or dealers are comparable, the Sub-Advisor
                  may, at its discretion,  execute transactions with brokers and
                  dealers who provide the Trust with  research  advice and other
                  services,  but in all  instances  best net price and execution
                  shall control.

                  On occasions when the  Sub-Advisor  deems the purchase or sale
                  of a security  to be in the best  interest of the Fund as well
                  as its  other  clients,  the  Sub-Advisor  may  to the  extent
                  permitted by  applicable  law, but shall not be obligated  to,
                  aggregate the securities to be sold or purchased with those of
                  its other clients. In such event, allocation of the securities
                  so  purchased  or sold  will be made by the  Sub-Advisor  in a
                  manner it considers to be equitable  and  consistent  with its
                  fiduciary  obligations to the Trust and to such other clients.
                  Securities so allocated will be delivered in proportion to the
                  consideration  paid. The expenses  incurred in the transaction
                  shall be allocated pro-rata.

         B.       Foreign Exchange  Transactions.  The Sub-Advisor is authorized
                  to effect,  on behalf of the Fund,  spot and  forward  foreign
                  exchange  contracts  for purposes  consistent  with the Fund's
                  investment  objectives and policies as described in the Fund's
                  Prospectus  and  Statement  of  Additional   Information,   as
                  amended, and with such other operating policies and guidelines
                  as ACIM may from time to time provide to the Sub-Advisor.  The
                  Sub-Advisor is further authorized to execute such documents as
                  may be required to effect such transactions. In effecting such
                  spot and forward foreign  exchange  contracts and in selecting
                  counterparties  for such contracts,  the Sub-Advisor shall use
                  its best efforts to seek the best overall terms  available and
                  shall execute or direct the execution of all such transactions
                  as  permitted  by law and in a  manner  that  best  suits  the
                  interests of the Fund and its shareholders.

IV.      INFORMATION  PROVIDED TO THE TRUST. The Sub-Advisor will keep the Trust
         and ACIM  informed of  developments  materially  affecting the Fund and
         will  take  initiative  to  furnish  the  Trust  and ACIM on at least a
         quarterly basis with whatever  information the Sub-Advisor  believes is
         appropriate  for this  purpose.  Such regular  quarterly  reports shall
         include  (i) a  discussion  of the Fund's  performance  relative to its
         benchmark,  (ii) an assessment of investment  decisions and analysis of
         the  components of the Fund's  performance  (i.e.,  bond  selection and
         currency hedging),  (iii) the decisions it has made with respect to the
         Fund's  assets and the purchase and sale of its  portfolio  securities,
         (iv) the reasons for such  decisions and related  actions,  and (v) the
         extent to which those decisions have been implemented.

         Sub-Advisor  will  provide  the Trust  and ACIM  with  such  investment
         records,   ledgers,   accounting  and   statistical   data,  and  other
         information  as the  Trust  or ACIM  requires  for the  preparation  of
         registration statements, periodic and other reports and other documents
         required by federal and state laws and regulations, and particularly as
         may  be  required  for  the  periodic  review,  renewal,  amendment  or
         termination  of this  Agreement,  and  such  additional  documents  and
         information  as the  Trust  and ACIM  may  reasonably  request  for the
         management of their affairs. At least once annually a representative of
         the Sub-Advisor shall attend a meeting of the Board of Trustees to make
         a presentation on the Fund's performance during the preceding year.

         The Sub-Advisor shall furnish to regulatory authorities any information
         or  reports  in  connection  with  such  services  as may  be  lawfully
         requested.  The Sub-Advisor shall also, at the Trust's request, certify
         to the Trust's independent  auditors that sales or purchases aggregated
         with those of other clients of the Sub-Advisor, as described in Section
         3(a) above, were equitably allocated.

         In compliance with the  requirements  of the Investment  Company Act of
         1940, the Sub-Advisor  hereby agrees that all records that it maintains
         for the Fund are the  property  of the  Trust  and  further  agrees  to
         surrender  promptly to the Trust any of such  records  upon the Trust's
         request. Sub-Advisor further agrees to preserve for the periods of time
         prescribed  by the  Investment  Company Act of 1940 and the  Investment
         Advisers Act of 1940 the records required to be maintained thereunder.

V.       LIABILITY AND INDEMNIFICATION OF THE SUB-ADVISOR. The Sub-Advisor shall
         be responsible  for the exercise of reasonable care in carrying out its
         responsibilities  hereunder;  provided,  however,  that no provision of
         this  Agreement  shall be construed  to protect any trustee,  director,
         officer,  agent or employee of the Sub-Advisor from liability by reason
         of negligence,  willful  malfeasance,  bad faith in the  performance of
         such person's duties or by reason of reckless  disregard of obligations
         and duties hereunder.

         ACIM shall indemnify and hold harmless the Sub-Advisor from and against
         all  claims,  losses,  liabilities  or  damages  (including  reasonable
         attorneys  fees  and  other  related  expenses),  arising  from  or  in
         connection  with  the  performance  by the  Sub-Advisor  of its  duties
         hereunder and not resulting from the Sub-Advisor's negligence,  willful
         malfeasance, bad faith in the performance of its duties or by reason of
         its reckless disregard of obligations and duties hereunder.

VI.      COMPENSATION.  In  consideration of the services  rendered  pursuant to
         this Agreement, ACIM will pay the Sub-Advisor on the first business day
         of each month a fee for the previous  month at an annual rate  computed
         as follows:

            0.20% of the Fund's average daily net assets up to $200 million; and
            0.15% of the Fund's average daily net assets over $200 million.

         The  Sub-Advisor  shall have no right to obtain  compensation  directly
         from the Fund or the Trust for services  provided  hereunder and agrees
         to look solely to ACIM for  payment of fees due.  Upon  termination  of
         this Agreement  before the end of a month, the fee for that month shall
         be prorated  according to the proportion  that such period bears to the
         full monthly  period and shall be payable upon the date of  termination
         of this Agreement.  For the purpose of determining  fees payable to the
         Sub-Advisor,  the value of the Fund's net assets  shall be  computed at
         the times and in the  manner  specified  in the  Fund's  Prospectus  or
         Statement of Additional Information.

VII.     EXPENSES. The Sub-Advisor will bear all expenses in connection with the
         performance of its services under this Agreement,  which expenses shall
         not  include  brokerage  fees or  commissions  in  connection  with the
         execution of securities transactions.

VIII.    SERVICES TO OTHER COMPANIES OR ACCOUNTS. The Trust understands that the
         Sub-Advisor now acts, will continue to act as investment advisor to one
         or more other investment  companies or series of investment  companies.
         The Trust has no objection to the Sub-Advisor so acting, provided that,
         as  described  in  Section 3 above,  whenever  the Fund and one or more
         other accounts or investment  companies advised by the Sub-Advisor have
         funds  available for investment,  investments  suitable and appropriate
         for each will be allocated  equitably to each entity in accordance with
         procedures.  Similarly,   opportunities  to  sell  securities  will  be
         allocated in an equitable  manner.  In addition,  the Trust understands
         that  the  persons  employed  by  the  Sub-Advisor  to  assist  in  the
         performance of the Sub-Advisor's duties hereunder will not devote their
         full time to such service and nothing  contained herein shall be deemed
         to limit or restrict the right of the  Sub-Advisor  or any affiliate of
         the  Sub-Advisor  to engage in and devote time and  attention  to other
         business or to render services of whatever kind or nature.

IX.      TERM OF AGREEMENT. This Agreement shall become effective as of the date
         the Fund commences its  investment  operations and shall continue for a
         two-year  term  and   thereafter  so  long  as  such   continuance   is
         specifically approved at least annually by (i) the Board of Trustees of
         the Trust or (ii) a vote of a "majority"  (as defined in the Investment
         Company  Act of 1940,  as  amended)  of the Fund's  outstanding  voting
         securities,  provided  that in  either  event the  continuance  is also
         approved by a majority of the Board of Trustees who are not "interested
         persons" (as defined in said Act) of any part to this  Agreement,  by a
         vote cast in person at a meeting  called  for the  purpose of voting on
         such  approval.  This Agreement is  terminable,  without  penalty on 60
         days' written  notice,  by ACIM, the Board of Trustees of the Trust, or
         by vote of holders of a majority of the Fund's  shares,  or upon twelve
         months'  written  notice  by  the   Sub-Advisor,   and  will  terminate
         automatically upon any termination of the management  agreement between
         the Trust and ACIM. In addition,  this  Agreement  will also  terminate
         automatically  in the event of its assignment (as defined in said Act).
         The Sub-Advisor  agrees to notify the Trust of any  circumstances  that
         might result in this Agreement being deemed to be assigned.

X.       REPRESENTATIONS OF THE TRUST AND THE SUB-ADVISOR.  The Trust represents
