Statement of Additional Information                                            1


INVESTMENT OBJECTIVES OF THE FUNDS

     The investment  objective of each fund comprising  American Century Capital
Portfolios,  Inc.  is  described  on  page 2 of the  applicable  prospectus.  In
achieving its objective, a fund must conform to certain policies,  some of which
are designated in its prospectus or in this Statement of Additional  Information
as  "fundamental"  and  cannot be  changed  without  shareholder  approval.  The
following  paragraph is also a statement of  fundamental  policy with respect to
selection of investments for Value and Equity Income.

     In general,  within the restrictions outlined herein,  American Century has
broad  powers  with  respect  to  investing  funds or holding  them  uninvested.
Investments are varied according to what is judged  advantageous  under changing
economic  conditions.  It  is  our  policy  to  retain  maximum  flexibility  in
management without restrictive provisions as to the proportion of one or another
class of securities  that may be held,  subject to the  investment  restrictions
described  below.  It is the manager's  intention  that each fund will generally
consist  of equity  securities.  However,  subject to the  specific  limitations
applicable  to a fund,  the  manager  may invest the assets of a fund in varying
amounts  in  other  instruments  and  in  senior  securities,   such  as  bonds,
debentures,  preferred  stocks  and  convertible  issues,  when such a course is
deemed appropriate in order to attempt to attain its financial objective.

     Neither the  Securities  and Exchange  Commission  nor any other federal or
state agency  participates in or supervises the management of the funds or their
investment practices or policies.

INVESTMENT RESTRICTIONS

     Additional  fundamental  policies that may be changed only with shareholder
approval provide as follows:

     (1) The funds shall not issue senior securities,  except as permitted under
the Investment Company Act of 1940.

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

     (3) The funds  shall not lend any  security or make any other loan if, as a
result,  more  than 33 1/3% of a  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) The funds shall not purchase or sell real estate  unless  acquired as a
result of ownership of  securities or other  instruments.  This policy shall not
prevent the funds 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) The  funds  shall not act as an  underwriter  of  securities  issued by
others, except to the extent that a fund may be considered an underwriter within
the  meaning of the  Securities  Act of 1933 in the  disposition  of  restricted
securities.

     (6) The funds  shall  not  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 funds from  purchasing  or selling
options  and  futures  contracts  or  from  investing  in  securities  or  other
instruments backed by physical commodities.

     (7) The funds shall not invest for  purposes  of  exercising  control  over
management.

     (8) Value and Equity  Income shall not  concentrate  their  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).

     In  addition,   the  funds  have  adopted  the  following   non-fundamental
investment restrictions:

     (1) As an operating policy, a fund shall not purchase additional investment
securities  at any time during  which  outstanding  borrowings  exceed 5% of the
total assets of the fund.

     (2) As an operating  policy,  a fund may not purchase any security or enter
into a repurchase

2                                                   American Century Investments


agreement if, as a result, more than 15% of its net assets (10% for money market
funds) 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.

     (3) As an operating policy, a fund 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  transaction in futures  contracts
and options are not deemed to constitute selling securities short.

     (4) As an operating policy, a fund shall not purchase securities on margin,
except that a 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.

     The Investment  Company Act imposes certain  additional  restrictions  upon
acquisition by the fund of securities  issued by insurance  companies,  brokers,
dealers,  underwriters  or  investment  advisors,  and  upon  transactions  with
affiliated persons as therein defined.  It also defines and forbids the creation
of cross and circular ownership.

     Neither Value nor Equity Income may  concentrate  their  investments in the
securities of issuers  engaged in a single  industry.  In  determining  industry
groups for purposes of this  restriction,  the SEC ordinarily  uses the Standard
Industry   Classification  codes  developed  by  the  United  States  Office  of
Management and Budget. In the interest of ensuring adequate diversification, the
funds monitor industry  concentration  using a more restrictive list of industry
groups  than that the  recommended  by the SEC.  The funds  believe  that  these
classifications  are reasonable  and are not so broad that the primary  economic
characteristics of the companies in a single class are materially different. The
use of these more restrictive industry  classifications may, however,  cause the
funds to forego  investment  possibilities  which may  otherwise be available to
them under the Investment Company Act.

     Neither  the SEC nor any other  agency of the  federal or state  government
participates  in  or  supervises  the  funds'  management  or  their  investment
practices or policies.

FORWARD CURRENCY EXCHANGE CONTRACTS

     A fund conducts its foreign currency exchange transactions either on a spot
(ie., cash) basis at the spot rate prevailing in the foreign  currency  exchange
market or through entering into forward currency exchange  contracts to purchase
or sell foreign currencies.

     A fund expects to use forward contracts under two circumstances:

     (1) When  the  manager  wishes  to "lock  in" the  U.S.  dollar  price of a
security  when a fund is  purchasing  or  selling a  security  denominated  in a
foreign currency,  the fund would be able to enter into a forward contract to do
so; or

     (2) When the manager  believes  that the currency of a  particular  foreign
country may suffer a substantial  decline against the U.S.  dollar, a fund would
be able to enter into a forward  contract  tosell  foreign  currency for a fixed
U.S.  dollar  amount  approximating  the  value of some or all of its  portfolio
securities  either  denominated  in,  or whose  value is tied to,  such  foreign
currency.

     As to the  first  circumstance,  when a fund  enters  into a trade  for the
purchase  or sale of a security  denominated  in a foreign  currency,  it may be
desirable to establish (lock in) the U.S.  dollar cost or proceeds.  By entering
into  forward  contracts  in U.S.  dollars for the purchase or sale of a foreign
currency involved in an underlying security  transaction,  the fund will be able
to protect  itself  against a possible loss between trade and  settlement  dates
resulting from the adverse change in the  relationship  between the U.S.  dollar
and the subject foreign currency.

     Under  the  second  circumstance,   when  the  manager  believes  that  the
currency of a particular  country may suffer a substantial  decline  relative to
the U.S.  dollar,  a fund  could  enter  into a forward  contract  to sell for a
fixed dollar  amount the amount in foreign  currencies  approximating  the value
of some or all of its  portfolio  securities  either  denominated  in,  or whose
value is tied to, such foreign currency. The

Statement of Additional Information                                            3


fund will place cash or high-grade  liquid securities in a separate account with
its custodian in an amount equal to the value of the forward  contracts  entered
into under the second circumstance. If the value of the securities placed in the
separate account  declines,  additional cash or securities will be placed in the
account on a daily basis so that the value of the  account  equals the amount of
the fund's commitments with respect to such contracts.

     The  precise  matching  of forward  contracts  in the amounts and values of
securities  involved  generally would not be possible since the future values of
such foreign  currencies will change as a consequence of market movements in the
values of those securities between the date the forward contract is entered into
and the date it matures.  Predicting  short-term  currency  market  movements is
extremely  difficult,  and the  successful  execution  of a  short-term  hedging
strategy is highly  uncertain.  The  manager  does not intend to enter into such
contracts  on a regular  basis.  Normally,  consideration  of the  prospect  for
currency parities will be incorporated into the long-term  investment  decisions
made with respect to overall  diversification  strategies.  However, the manager
believes  that it is  important to have  flexibility  to enter into such forward
contracts when it determines that a fund's best interests may be served.

     Generally,  a fund will not enter  into a forward  contract  with a term of
greater  than one year.  At the maturity of the forward  contract,  the fund may
either sell the portfolio security and make delivery of the foreign currency, or
it may retain the security and terminate  the  obligation to deliver the foreign
currency by purchasing an "offsetting"  forward  contract with the same currency
trader  obligating  the fund to purchase,  on the same maturity  date,  the same
amount of the foreign currency.

     It is impossible  to forecast  with absolute  precision the market value of
portfolio securities at the expiration of the forward contract.  Accordingly, it
may be necessary for a fund to purchase  additional foreign currency on the spot
market  (and bear the  expense  of such  purchase)  if the  market  value of the
security is less than the amount of foreign  currency  the fund is  obligated to
deliver and if a decision is made to sell the security and make  delivery of the
foreign currency the fund is obligated to deliver.

INDEX FUTURES CONTRACTS

     As  described in the  applicable  Prospectus,  Value and Equity  Income may
enter into domestic stock index futures contracts.  Unlike when a fund purchases
securities,  no purchase price for the underlying securities is paid by the fund
at the time it purchases a futures  contract.  When an index futures contract is
entered into,  both the buyer and seller of the contract are required to deposit
with a futures commission merchant ("FCM") cash or high-grade debt securities in
an amount equal to a percentage of the contract's  value, as set by the exchange
on which the contract is traded. This amount is known as "initial margin" and is
held by the  fund's  custodian  for the  benefit  of the FCM in the event of any
default by the fund in the payment of any future obligations.

     The value of the index  futures  contract is adjusted  daily to reflect the
fluctuation of the value of the underlying  securities  that comprise the index.
This is a process  known as marking the  contract  to market.  If the value of a
party's position declines,  that party is required to make additional "variation
margin"  payments to the FCM to settle the change in value. The party that has a
gain may be  entitled to receive  all or a portion of this  amount.  The FCM may
have  access to a fund's  margin  account  only under  specified  conditions  of
default.

     The funds  maintain  from time to time a percentage of their assets in cash
or high-grade liquid securities to provide for redemptions or to hold for future
investment in securities consistent with the funds' investment  objectives.  The
funds may enter into index futures contracts as an efficient means to expose the
funds' cash position to the domestic  equity market.  The manager  believes that
the purchase of futures  contracts is an efficient means to effectively be fully
invested in equity securities.

     The funds intend to comply with  guidelines  of  eligibility  for exclusion
from the  definition  of the  term  "commodity  pool  operator"  adopted  by the
Commodity Futures Trading Commission and the National Futures Association, which
regulate trading in the futures markets.  To do so, the aggregate initial margin
required to establish  such positions may not exceed 5% of the fair market value
of a fund's net assets, after taking into account unrealized profits and

4                                                   American Century Investments


unrealized losses on any contracts it has entered into.

     The principal risks generally associated with the use of futures include:

     o   the possible  absence of a liquid  secondary  market for any particular
         instrument  may make it difficult or impossible to close out a position
         when desired (liquidity risk);

     o   the risk that the counter party to the contract may fail to perform its
         obligations  or the  risk  of  bankruptcy  of the  FCM  holding  margin
         deposits (counter party risk);

     o   the risk that the index of  securities  to which the  futures  contract
         relates may go down in value (market risk); and

     o   adverse price  movements in the  underlying  index can result in losses
         substantially  greater  than the value of a fund's  investment  in that
         instrument because only a fraction of a contract's value is required to
         be deposited as initial margin (leverage risk); provided, however, that
         the funds may not purchase leveraged  futures,  so there is no leverage
         risk involved in the funds' use of futures.

     A liquid secondary market is necessary to close out a contract.  A fund may
seek to manage  liquidity  risk by investing  only in  exchange-traded  futures.
Exchange-traded  index  futures  pose less risk that  there will not be a liquid
secondary market than privately negotiated  instruments.  Through their clearing
corporations, the futures exchanges guarantee the performance of the contracts.

     Futures contracts are generally settled within a day from the date they are
closed out, as compared to three days for most types of equity securities.  As a
result,  futures  contracts can provide more liquidity than an investment in the
actual underlying securities.  Nevertheless, there is no assurance that a liquid
secondary  market  will  exist  for  any  particular  futures  contract  at  any
particular time.  Liquidity may also be influenced by an exchange-imposed  daily
price fluctuation  limit,  which halts trading if a contract's price moves up or
down more than the established  limit on any given day. On volatile trading days
when the price fluctuation limit is reached,  it may be impossible for a fund to
enter into new  positions  or close out  existing  positions.  If the  secondary
market for a futures contract is not liquid because of price fluctuation  limits
or otherwise,  a fund may not be able to promptly liquidate  unfavorable futures
positions  and  potentially  could be  required  to  continue  to hold a futures
position  until  liquidity in the market is  re-established.  As a result,  such
fund's access to other assets held to cover its futures  positions also could be
impaired until liquidity in the market is re-established.

     A fund manages  counter-party  risk by investing in  exchange-traded  index
futures.  In the event of the  bankruptcy of the FCM that holds margin on behalf
of a fund,  that fund may be  entitled to the return of margin owed to such fund
only in  proportion  to the amount  received by the FCM's other  customers.  The
manager will attempt to minimize the risk by monitoring the  creditworthiness of
the FCMs with which the funds do business.

     The  prices of futures  contracts  depend  primarily  on the value of their
underlying  instruments.  As a result,  the  movement  in market  price of index
futures contracts will reflect the movement in the aggregate market price of the
entire  portfolio of securities  comprising  the index.  Since the funds are not
index  funds,  a fund's  investment  in  futures  contracts  will not  correlate
precisely with the performance of such fund's other equity investments. However,
the manager  believes  that an  investment  in index  futures  will more closely
reflect  the  investment  performance  of the funds than an  investment  in U.S.
government or other highly liquid,  short-term debt  securities,  which is where
the cash position of the funds would otherwise be invested.

     The policy of the manager is to remain fully invested in equity securities.
There may be times when the manager  deems it  advantageous  to the funds not to
invest excess cash in index futures, but such decision will generally not be the
result of an active effort to use futures to time or anticipate market movements
in general.

AN EXPLANATION OF FIXED INCOME SECURITIES RATINGS

     As described in the applicable prospectuses,  the funds may invest in fixed
income  securities.  With the exception of convertible  securities and all fixed
income  investments  of the Real  Estate  Fund,  the  funds may  invest  only in
investment grade obligations.

     Fixed  income  securities  ratings  provide  the  investment  manager  with
current assessment of the credit

Statement of Additional Information                                            5


rating of an issuer  with  respect  to a specific  fixed  income  security.  The
following  is a  description  of the rating  categories  utilized  by the rating
services referenced in the prospectus disclosure:

     The following  summarizes the ratings used by Standard & Poor's Corporation
for bonds:

     AAA - This is the highest rating  assigned by S&P to a debt  obligation and
indicates an extremely strong capacity to pay interest and repay principal.

     AA - Debt rated AA is  considered  to have a very  strong  capacity  to pay
interest and repay principal and differs from AAA issues only to 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.

     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,  which  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 rating.

     C - The rating C typically is 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 rating CI is  reserved  for income  bonds on which no  interest is
being paid.

     D - Debt rated D is in payment default.  The D rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired,  unless S&P believes that such payments
will be made during such grace  period.  The D rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

     To provide more detailed indications of credit quality, the ratings from AA
to CCC may be modified by the addition of a plus or minus sign to show  relative
standing within these major rating categories.

     The following  summarizes  the ratings used by Moody's  Investors  Service,
Inc. for bonds:

     Aaa - Bonds that are rated Aaa are judged to be of the best  quality.  They
carry the smallest  degree of 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 comprise 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

6                                                   American Century Investments


be other elements  present that make the long-term risk appear  somewhat  larger
than the 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 some time in the future.

     Baa - Bonds that are rated Baa are considered as  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 the 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 small.

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

     Ca - Bonds that are rated Ca represent  obligations that are speculative in
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.

     Moody's  applies  numerical  modifiers  1, 2 and 3 in each  generic  rating
category  from Aa through B. The modifier 1 indicates  that the bond being rated
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking;  and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

SHORT SALES

     Value and Equity  Income  may engage in short  sales if, at the time of the
short  sale,  the fund owns or has the right to acquire  an equal  amount of the
security being sold short.

     In a short sale,  the seller does not  immediately  deliver the  securities
sold and is said to have a short  position in those  securities  until  delivery
occurs.  To make delivery to the  purchaser,  the executing  broker  borrows the
securities being sold short on behalf of the seller. While the short position is
maintained,  the seller  collateralizes its obligation to deliver the securities
sold  short in an  amount  equal  to the  proceeds  of the  short  sale  plus an
additional  margin amount  established  by the Board of Governors of the Federal
Reserve.  If a fund  engages in a short sale,  the  collateral  account  will be
maintained by the fund's custodian. There will be certain additional transaction
costs  associated  with short sales,  but the fund will endeavor to offset these
costs with income from the investment of the cash proceeds of short sales.

     A fund may make a short sale, as described above, when it wants to sell the
security  it owns at a  current  attractive  price  but  also  wishes  to  defer
recognition  of gain or loss for federal income tax purposes and for purposes of
satisfying certain tests applicable to regulated  investment companies under the
Internal  Revenue Code. In such a case, all or some part of any future losses in
the fund's long position in  substantially  identical  securities may not become
deductible  for tax  purposes  until all or some part of the short  position has
been closed.

PORTFOLIO TURNOVER

     In order to achieve  each fund's  investment  objective,  the manager  will
purchase and sell  securities  without regard to the length of time the security
has been  held.  Accordingly,  the  funds'  rate of  portfolio  turnover  may be
substantial.

     The funds intend to purchase a given security whenever the manager believes
it will contribute to the stated  objective of a fund, even if the same security
has only recently been sold. In selling a given  security,  the manager keeps in
mind that (1) profits from sales of securities  held less than three months must
be limited in order to meet the requirements of

Statement of Additional Information                                            7


Subchapter  M of the  Internal  Revenue  Code,  and (2)  profits  from  sales of
securities  are taxed to  shareholders.  Subject  to those  considerations,  the
corporation  will sell a given  security,  no matter for how long or how short a
period it has been held in the portfolio and no matter  whether the sale is at a
gain or at a loss,  if management  believes that the security is not  fulfilling
its  purpose,  either  because,  among other  things,  it did not live up to the
manager's  expectations,  or because it may be replaced  with  another  security
holding greater  promise,  or because it has reached its optimum  potential,  or
because of a change in the circumstances of a particular  company or industry or
in general economic conditions, or because of some combination of such reasons.

     When a  general  decline  in  security  prices is  anticipated,  a fund may
decrease  or  eliminate  entirely  its equity  position  and  increase  its cash
position,  and when a rise in price levels is  anticipated,  a fund may increase
its equity  position  and  decrease  its cash  position.  It should be expected,
however,  that the funds will, under most  circumstances,  be essentially  fully
invested in equity securities and equity equivalents.

     Since investment decisions are based on the anticipated contribution of the
security in question to a fund's objectives,  management  believes that the rate
of portfolio  turnover is  irrelevant  when  management  believes a change is in
order to achieve those objectives.

     The Board of  Directors  has  established  four  standing  committees,  the
Executive  Committee,  the Audit  Committee,  the  Compliance  Committee and the
Nominating Committee.

     Messrs.  Stowers Jr.,  Stowers III, and Lundgaard  constitute the Executive
Committee of the Board of Directors. The committee performs the functions of the
Board of Directors between meetings of the Board,  subject to the limitations on
its power set out in the  Maryland  General  Corporation  Law,  and  except  for
matters  required  by the  Investment  Company Act to be acted upon by the whole
Board.

     Messrs.   Lundgaard  (chairman),   Doering  and  Hock  and  Ms.  Strandjord
constitute the Audit  Committee.  The functions of the Audit  Committee  include
recommending the engagement of the funds' independent accountants, reviewing the
arrangements for and scope of the annual audit,  reviewing  comments made by the
independent accountants with respect to internal controls and the considerations
given or the  corrective  action taken by  management,  and  reviewing  nonaudit
services provided by the independent accountants.

     Messrs.  Brown  (chairman),  Pratt and  Silver  constitute  the  Compliance
Committee.  The  functions of the  Compliance  Committee  include  reviewing the
results of the funds' compliance  testing program,  reviewing  quarterly reports
from  the  manager  to  the  Board  regarding  various  compliance  matters  and
monitoring the implementation of the funds' Code of Ethics, including violations
thereof.

     The Nominating  Committee has as its principal role the  consideration  and
recommendation  of  individuals  for  nomination  as  directors.  The  names  of
potential  director  candidates  are drawn from a number of  sources,  including
recommendations  from members of the Board,  management and  shareholders.  This
committee  also reviews and makes  recommendations  to the Board with respect to
the composition of Board committees and other Board-related  matters,  including
its   organization,   size,   composition,   responsibilities,   functions   and
compensation.  The  members  of  the  nominating  committee  are  Messrs.  Pratt
(chairman), Lundgaard and Stowers III.

     The  Directors of the  corporation  also serve as Directors for other funds
advised by the  manager.  Each  Director  who is not an  "interested  person" as
defined in the  Investment  Company Act  receives for service as a member of the
Board of six of such  companies an annual  director's  fee of $44,000,  a fee of
$1,000 per regular Board meeting attended and $500 per special Board meeting and
committee meeting attended. In addition, those Directors who are not "interested
persons" who serve as chairman of a committee of the Board of Directors  receive
an  additional  $2,000 for such  services.  These fees and  expenses are divided
among the six investment  companies based upon their relative net assets.  Under
the  terms  of  the  management  agreement  with  the  manager,  the  funds  are
responsible for paying such fees and expenses.

     Set forth on page 10 is the  aggregate  compensation  paid for the  periods
indicated by the  corporation  and by the American  Century family of funds as a
whole to each director of the corporation  who is not an "interested  person" as
defined in the Investment Company Act.

MANAGEMENT

     A description of the  responsibilities  and method of  compensation  of the
funds' manager,  American Century Investment  Management,  Inc., appears in each
Prospectus under the caption "Management."

     During the three most recent  fiscal  years,  the  management  fees paid by
Value and Equity Income were as follows:

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

* Since inception (August 1, 1994) through March 31, 1995.

     The Advisor Class of Value commenced October 2, 1996, and the Advisor Class
of Equity  Income  commenced  March 7, 1997.  The  management  fees shown  above
include  $106,780  paid on Advisor  Class shares of Value and $9 paid on Advisor
Class shares of Equity Income for the period ended March 31, 1997.

     The management  agreements between Value, Equity Income and the Real Estate
Fund  and the  manager  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 (i) the funds'
Board of Directors or by the vote of a majority of outstanding votes (as defined
in the  Investment  Company  Act)  and  (ii) by the  vote of a  majority  of the
Directors  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.

     Each  management  agreement  provides that it may be terminated at any time
without payment of any penalty by the funds' Board of Directors, or by a vote of
the funds'  shareholders,  on 60 days' written notice to the manager and that it
shall be automatically terminated if it is assigned.

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

     Each management  agreement also provides that the manager and its officers,
directors 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.

     The  management  agreement  between  the Real  Estate  Fund and the manager
contemplates the retention of a subadvisor by the manager.

     Certain  investments  may be  appropriate  for the funds and also for other
clients  advised by the manager.  Investment  decisions  for the funds 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 in different amounts and
at  different  times for more than one but less than all  clients.  In addition,
purchases  or sales of the same  security may be made for two or more clients 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 a fund.

     The  manager  may  aggregate  purchase  and sale  orders of the funds  with
purchase  and sale orders of its other  clients when the manager  believes  that
such aggregation  provides the best execution for the funds. The funds' Board of
Directors has approved the policy of the manager with respect to the aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the funds  participate 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  funds  unless  it
believes such  aggregation is consistent with its duty to seek best execution on
behalf  of the  funds and the terms of the  management  agreement.  The  manager
receives  to  additional  compensation  or  remuneration  as a  result  of  such
aggregation.

     In  addition  to  managing  the  funds  the  manager  is also  acting as an
investment adviser to twelve institu-

tional accounts and to five registered  investment  companies:  American Century
Mutual Funds, Inc.,  American Century Premium Reserves,  Inc.,  American Century
World Mutual Funds, Inc.,  American Century Strategic Asset  Allocations,  Inc.,
and American Century Variable Portfolios, Inc.

     American  Century  Services   Corporation   provides  physical  facilities,
including  computer  hardware  and software  and  personnel,  for the day-to day
administration  of the funds and the  manager  pays  American  Century  Services
Corporation for such services.

     As  stated  in  each  Prospectus,  all of the  stock  of  American  Century
Investment  Management,  Inc. and American Century Services Corporation is owned
by American Century Companies, Inc.

CUSTODIANS

     Chase  Manhattan  Bank,  770  Broadway,  10th  Floor,  New  York,  New York
10003-9598,  and Commerce Bank, N.A., 1000 Walnut,  Kansas City, Missouri 64105,
each serves as custodian of the assets of the funds. The custodians take no part
in  determining  the  investment  policies  of the  funds or in  deciding  which
securities are purchased or sold by the funds. The funds, however, may invest in
certain  obligations  of  the  custodians  and  may  purchase  or  sell  certain
securities from or to the custodians.

INDEPENDENT AUDITORS

     At a meeting  held on December  12,  1996,  the Board of  Directors  of the
corporation  appointed  Deloitte & Touche  LLP,  1010 Grand  Avenue,  Suite 400,
Kansas City, Missouri 64106 as the independent  auditors of the funds to examine
the financial statements of the funds for the fiscal year ending March 31, 1998.
The  appointment of Deloitte & Touche was  recommended by the Audit Committee of
the Board of Directors.  As the  independent  auditors of the funds,  Deloitte &
Touche  will  provide  services  including  (1)  audit of the  annual  financial
statements,  (2) assistance and  consultation in connection with SEC filings and
(3)  review of the  annual  federal  income  tax  return  filed for each fund by
American Century.

     Ernst & Young LLP, One Kansas City Place,  1200 Main  Street,  Kansas City,
Missouri  64105,  served as  independent  auditors  for the funds for all fiscal
years ending prior to March 31, 1998.

CAPITAL STOCK

     The funds' capital stock is described in the Prospectuses under the heading
"Further Information About American Century."

     The corporation currently has two series of shares outstanding, and a third
series is planned to be  authorized.  Each  series of shares is further  divided
into four classes,  and the contemplated third series will be divided into three
classes.  The funds may in the  future  issue one or more  additional  series or
class of shares without a vote of the shareholders. The assets belonging to each
series or class of shares are held separately by the custodian and the shares of
each series or class represent a beneficial interest in the principal,  earnings
and profits (or losses) of  investment  and other assets held for that series or
class.  Your rights as a  shareholder  are the same for all series or classes of
securities unless otherwise stated. Within their respective series or class, all
shares will have equal redemption rights. Each share, when issued, is fully paid
and non-assessable.  Each share, irrespective of series or class, is entitled to
one vote for each  dollar of net asset  value  represented  by such share on all
questions.

     In  the  event  of  complete  liquidation  or  dissolution  of  the  funds,
shareholders of each series or class of shares will be entitled to receive,  pro
rata, all of the assets less the liabilities of that series or class.

     As of May 5,  1997,  in  excess of 5% of the  outstanding  shares of either
series of the funds were owned of record as follows:  Charles  Schwab & Co., San
Francisco, California, owned 12.5% of Value and 13.7% of Equity Income.

MULTIPLE CLASS STRUCTURE

     The  funds'  Board of  Directors  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 four classes of shares:  an Investor  Class,  an
Institutional Class, a Service Class and an Advisor Class.

     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,

Statement of Additional Information                                           11


without any load or commission.  The Institutional,  Service 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  management fee. In
addition to the management fee,  however,  Service Class shares are subject to a
Shareholder  Services Plan (described  below),  and the Advisor Class shares are
subject to a Master  Distribution and Shareholder  Services Plan (also described
below).  Both plans  have been  adopted by the  funds'  Board of  Directors  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  Directors  and  approved  by its  shareholders.
Pursuant to such rule,  the Board of Directors  and initial  shareholder  of the
funds'  Service  Class and  Advisor  Class  have  approved  and  entered  into a
Shareholder  Services  Plan,  with  respect to the Service  Class,  and a Master
Distribution  and  Shareholder  Services Plan, with respect to the Advisor Class
(collectively, the "Plans"). Both Plans are described beginning on this page.

     In adopting  the Plans,  the Board of  Directors  (including  a majority of
directors  who are not  "interested  persons"  of the funds (as  defined  in the
Investment Company Act),  hereafter referred to as the "independent  directors")
determined  that there was a reasonable  likelihood that the Plans would benefit
the funds and the shareholders of the affected classes.  Pursuant to Rule 12b-1,
information  with respect to revenues and expenses  under the Plans is presented
to the Board of Directors quarterly for its consideration in connection with its
deliberations as to the continuance of the Plans.  Continuance of the Plans must
be approved by the Board of Directors  (including a majority of the  independent
directors)  annually.  The  Plans  may be  amended  by a vote  of the  Board  of
Directors (including a majority of the independent  directors),  except that the
Plans 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 Plans terminate  automatically in the event of an assignment and may
be terminated upon a vote of a majority of the independent  directors 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.

SHAREHOLDER SERVICES PLAN

     As described in the  Prospectuses,  the funds'  Service  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.  In such circumstances,  certain record
keeping and  administrative  services  that are provided by the funds'  transfer
agent for the Investor Class shareholders may be performed by a plan sponsor (or
its agents) or by a financial  intermediary.  To enable the funds'  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 Service  Class shares and
the funds' Board of Directors has adopted a Shareholder  Services Plan. Pursuant
to the  Shareholder  Services  Plan,  the Service Class shares pay a shareholder
services fee of 0.25% annually of the aggregate  average daily net assets of the
funds' Service Class shares.

     American Century Investment Services,  Inc. enters into contracts with each
financial  intermediary  for the provision of certain  shareholder  services and
utilizes the shareholder  services fees under the  Shareholder  Services Plan to
pay for  such  services.  Payments  may be made  for a  variety  of  shareholder
services,  including,  but are not limited to, (1)  receiving,  aggregating  and
processing  purchase,  exchange and redemption  request from  beneficial  owners
(including  contract  owners of  insurance  products  that  utilize the funds as
underlying  investment  medium) of shares and  placing  purchase,  exchange  and
redemption  orders  with the  Distributor;  (2)  providing  shareholders  with a
service that invests the assets of their accounts in shares

12                                                  American Century Investments


pursuant to specific or  pre-authorized  instructions;  (3) processing  dividend
payments from a fund on behalf of  shareholders  and assisting  shareholders  in
changing dividend options, account designations and addresses; (4) providing and
maintaining  elective services such as check writing and wire transfer services;
(5) acting as  shareholder  of record and nominee  for  beneficial  owners;  (6)
maintaining account records for shareholders and/or other beneficial owners; (7)
issuing confirmations of transactions;  (8) providing subaccounting with respect
to shares  beneficially  owned by  customers of third  parties or providing  the
information  to a fund as necessary  for such  subaccounting;  (9) preparing and
forwarding   shareholder   communications  from  the  funds  (such  as  proxies,
shareholder reports,  annual and semi-annual  financial statements and dividend,
distribution and tax notices) to shareholders  and/or other  beneficial  owners;
(10) providing other similar  administrative  and sub-transfer  agency services;
and (11)  paying  "service  fees"  for the  provision  of  personal,  continuing
services to investors, as contemplated by the Rules of Fair Practice of the NASD
(collectively  referred to as "Shareholder  Services").  Shareholder Services do
not include those activities and expenses that are primarily  intended to result
in the sale of additional shares of the funds.

MASTER DISTRIBUTION AND SHAREHOLDER
SERVICES PLAN

     As described in the  Prospectuses,  the funds'  Advisor  Class of shares is
also 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 funds' shares in various  investment  products or in connection with various
financial services.

     As with the  Service  Class,  certain  record  keeping  and  administrative
services that are provided by the funds'  transfer  agent of 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  provide  various  distribution
services.

     To enable the funds'  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 funds'  Board of  Directors  has
adopted a Master  Distribution and Shareholder  Services Plan (the "Distribution
Plan").  Pursuant  to such Plan,  the  Advisor  Class  shares pay a fee of 0.50%
annually of the aggregate  average daily net assets of the funds'  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,  (1) the  payment  of  sales
commissions,  ongoing  commissions  and  other  payments  to  brokers,  dealers,
financial  institutions  or others who sell  Advisor  Class  shares  pursuant to
Selling  Agreements;  (2)  compensation to registered  representatives  or other
employees of  Distributor  who engage in or support  distribution  of the funds'
Advisor Class shares; (3) compensation to, and expenses  (including overhead and
telephone  expenses)  of,   Distributor;   (4)  the  printing  of  prospectuses,
statements  of  additional  information  and  reports  for other  than  existing
shareholders; (5) the preparation, printing and distribution of sales literature
and advertising  materials  provided to the funds'  shareholders and prospective
shareholders;  (6)  receiving  and  answering  correspondence  from  prospective
shareholders  including  distributing  prospectuses,  statements  of  additional
information,  and shareholder reports; (7) the providing of facilities to answer
questions  from  prospective  investors  about fund shares;  (8) complying  with
federal and state  securities  laws  pertaining to the sale of fund shares;  (9)
assisting  investors in completing  application forms and selecting dividend and
other  account  options:  (10) the providing of other  reasonable  assistance in
connection  with  the  distribution  of fund  shares;  (11) the  organizing  and
conducting  of  sales  seminars  and  payments  in  the  form  of  transactional
compensation or promotional incentives; (12) profit on the foregoing; (13) the

Statement of Additional Information                                           13


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 (14)
such other distribution and services activities as the manager determines may be
paid for by the funds  pursuant to the terms of this Agreement and in accordance
with Rule 12b-1 of the 1940 Act.

TAXES

     Each fund has  elected to be taxed  under the  Internal  Revenue  Code as a
regulated investment company. If they qualify,  they will not be subject to U.S.
federal  income tax on net investment  income and net capital  gains,  which are
distributed to its  shareholders  within  certain time periods  specified in the
Code.  Amounts not distributed on a timely basis would be subject to federal and
state corporate income tax and to a nondeductible 4% excise tax.

     Distributions  by the funds from net  investment  income and net short-term
capital  gains are taxable to  shareholders  as ordinary  income.  The dividends
received  deduction  available to corporate  shareholders for dividends received
from a fund will apply to ordinary income  distributions only to the extent that
they are attributable to the fund's dividend income from U.S.  corporations.  In
addition,  the dividends  received  deduction will be limited if the shares with
respect to which the dividends are received are treated as  debt-financed or are
deemed to have been held less than 46 days by a fund.

     Distributions by the funds from net long-term  capital gains are taxable to
a shareholder  as long-term  capital gains  regardless of the length of time the
shares on which such  distributions  are paid have been held by the shareholder.
However,  shareholders  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 the
shareholder with respect to such shares.

     Redemption  of shares of a fund will be a taxable  transaction  for federal
income tax purposes and shareholders will generally recognize 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.

     In addition to the federal income tax consequences described above relating
to an investment in shares of the funds,  there may be other  federal,  state or
local tax  considerations  that depend upon the circumstances of each particular
investor.  Prospective  shareholders  are  therefore  urged to consult their tax
advisers with respect to the effect of this investment on their own situations.

TAXATION OF CERTAIN MORTGAGE REITS

     The funds may invest in REITs that hold  residual  interests in real estate
mortgage investment conduits.  Under Treasury regulations that have not yet been
issued,  but may apply  retroactively,  a portion of a fund's income from a REIT
that is attributable to the REIT's residual  interest in a REMIC (referred to in
the Code as an "excess  inclusion") will be subject to Federal income tax in all
events.  These  regulations  are also expected to provide that excess  inclusion
income of a regulated  investment company,  such as a fund, will be allocated to
shareholders of the regulated  investment company in proportion to the dividends
received  by them with the same  consequences  as if the  shareholders  held the
related REMIC residual interest  directly.  In general,  excess inclusion income
allocated to shareholders  (i) cannot be offset by net operating losses (subject
to a limited exception for certain thrift institutions) and (ii) will constitute
unrelated  business  taxable income to entities  (including a qualified  pension
plan, an  individual  retirement  account,  a 401(k) plan, a Keogh plan or other
tax-exempt  entity)  subject  to  tax  on  unrelated  business  income,  thereby
potentially  requiring such an entity that is allocated excess inclusion income,
and otherwise  might be required to file a tax return,  to file a tax return and
pay tax on some income.  In  addition,  if at any time during any taxable year a
"disqualified organization" (as defined in the Code) is a record holder

14                                                  American Century Investments


of a share in a regulated  investment  company,  then the  regulated  investment
company will be subject to a tax equal to that  portion of its excess  inclusion
income for the taxable year that is allocable to the disqualified  organization,
multiplied by the highest Federal income tax rate imposed on corporations.

TAXATION OF DEBT INSTRUMENTS

     For Federal income tax purposes, debt securities purchased by the funds may
be treated as having  original  issue  discount.  Original  issue  discount  can
generally be defined as the excess of the stated redemption price at maturity of
a debt  obligation  over the issue price.  Original issue discount is treated as
interest earned by the fund for Federal income tax purposes,  whether or not any
income is  actually  received,  and  therefore  is subject  to the  distribution
requirements  of the Code.  However,  original  issue  discount  with respect to
tax-exempt  obligations generally will be excluded from a fund's taxable income.
Original  issue  discount with respect to  tax-exempt  securities is accrued and
added to the adjusted tax basis of such  securities  for purposes of determining
gain or loss upon sale or at maturity.  Generally,  the amount of original issue
discount  for any  period  is  determined  on the basis of a  constant  yield to
maturity  which takes into account the  compounding of accrued  interest.  Under
section 1286 of the Code, an  investment  in a stripped bond or stripped  coupon
will result in original issue discount.

     A fund may  purchase  debt  securities  at a  discount  which  exceeds  the
original issue price plus previously  accrued original issue discount  remaining
on the securities,  at the time of purchase. This additional discount represents
market discount for income tax purposes.  Generally,  market discount is accrued
on a daily basis.

     A fund may purchase debt securities at a premium, i.e., at a purchase price
in excess of face amount.  With respect to  tax-exempt  securities,  the premium
must be  amortized  to the  maturity  date but no  deduction  is allowed for the
premium amortization. Instead, the amortized bond premium will reduce the fund's
adjusted tax basis in the securities. For taxable securities, the premium may be
amortized if the fund so elects.  The amortized premium on taxable securities is
allowed as a deduction, and, generally for securities issued after September 27,
1985, must be amortized under an economic accrual method.

FOREIGN HOLDERS

     A foreign  holder is a person or entity that,  for U.S.  Federal income tax
purposes,  is a nonresident alien individual,  a foreign corporation,  a foreign
partnership,  or a  non-resident  fiduciary of a foreign  estate or trust.  If a
distribution of a fund's taxable income (without regard to its net capital gain)
to a foreign holder is not  effectively  connected with a U.S. trade of business
carried on by the investor, such distribution will be subject to withholding tax
at a 30% rate or such lower rate as may be specified by an applicable income tax
treaty.  In addition,  distributions  from the Fund will generally be subject to
information reporting.

     If at least  50% of the value of the Real  Estate  Fund is  represented  by
shares of REITs that are "domestically controlled" within the meaning of Section
897(h) of the Code,  or is  represented  by shares of classes of REIT stock that
(i) represent not more than 5% of such classes and (ii) are "regularly traded on
an established securities market" within the meaning of Section 897(c)(3) of the
Code,  a foreign  holder  should  not be subject  to  withholding  tax under the
Foreign  Investment  in Real  Property Tax Act with respect to gain arising from
the sale or redemption of units. In addition, based upon advice of counsel as to
existing law, the fund does not intend to withhold under FIRPTA on distributions
of the fund's net capital gain  (designated  as capital gain by the fund).  Such
income  generally will not be subject to federal income tax unless the income is
effectively  connected  with a trade or business of such  foreign  holder in the
United  States.  In the case of a foreign  holder  who is a  non-resident  alien
individual,  however,  gain  arising  from the sale or  redemption  of shares or
distributions  of the  fund's net  capital  gain  ordinarily  will be subject to
federal income tax at a rate of 30% if such individual is physically  present in
the U.S.  for 183 days or more during the  taxable  year and, in the case of the
gain  arising  from  the  sale  or  redemption  of  units,  either  the  gain is
attributable  to an office or other fixed place of  business  maintained  by the
holder in the

Statement of Additional Information                                           15


United States or the holder has a "tax home" in the United States.  In addition,
shares held by individual  who is not a citizen or resident of the United States
at the time of his death will  generally  be subject  to United  States  federal
estate tax.

     The tax  consequences to a foreign holder entitled to claim the benefits of
an applicable tax treaty may be different from those described  herein.  Foreign
Holders should consult their own tax advisers to determine whether investment in
the Fund is appropriate.

BROKERAGE

     Under  the terms of the  management  agreements  between  the funds and the
manager,  the manager has the  responsibility  of  selecting  brokers to execute
portfolio transactions. The funds' policy is to secure the most favorable prices
and execution of orders on its portfolio transactions. So long as that policy is
met, the manager may take into  consideration  the factors  discussed below when
selecting brokers.

     For  brokerage  services  related to the Real Estate Fund,  the manager has
delegated responsibility for selecting brokers to execute portfolio transactions
to the subadvisor under the terms of the Investment Subadvisory Agreement.

     The manager or the subadvisor, as the case may be, receives statistical and
other  information  and services  without  cost from  brokers and  dealers.  The
manager or the subadvisor evaluates such information and services, together with
all  other  information  that it may  have,  in  supervising  and  managing  the
investments  of the funds.  Because  such  information  and services may vary in
amount,  quality and  reliability,  their influence in selecting  brokers varies
from  none to very  substantial.  The  manager  and the  subadvisor  propose  to
continue to place some of the funds' brokerage business with one or more brokers
who provide information and services.  Such information and services provided to
the  manager  and the  subadvisor  will be in addition to and not in lieu of the
services  required to be performed for the funds by the manager and  subadvisor.
Neither the  manager  nor the  subadvisor  utilizes  brokers  who  provide  such
information  and  services  for the purpose of reducing the expense of providing
required services to the funds.

     In the years ended March 31, 1997, 1996 and 1995, the brokerage commissions
of Value and Equity Income were as follows:

VALUE                     $4,841,179       $2,929,681          $607,139

- -----------------------------------------------------------------------------
1Since inception.

     The brokerage  commissions  paid by the funds may exceed those that another
broker might have charged for  effecting  the same  transactions  because of the
value of the brokerage and/or research services provided by the broker. Research
services   furnished  by  brokers  through  whom  the  funds  effect  securities
transactions  may be used by the manager in servicing all of its  accounts,  and
not all such  services may be used by the manager in managing the  portfolios of
the funds.

     The  staff of the SEC has  expressed  the view  that  the  best  price  and
execution  of  over-the-counter  transactions  in  portfolio  securities  may be
secured by dealing directly with principal  market makers,  thereby avoiding the
payment of compensation to another broker. In certain  situations,  the officers
of the funds and the manager believe that the facilities,  expert  personnel and
technological systems of a broker enable the funds to secure as good a net price
by dealing with a broker instead of a principal market maker, even after payment
of  the   compensation   to  the  broker.   The  funds   normally   place  their
over-the-counter  transactions with principal market makers but also may deal on
a brokerage basis when utilizing electronic trading networks or as circumstances
warrant.

     On occasions  when the manager  deems the purchase or sale of a security to
be in the best interests of the funds as well as other fiduciary  accounts,  the
manager may  aggregate  the security to be sold or  purchased  for the fund with
those to be sold or purchased for other accounts in order to obtain the best net
price and most favorable  execution.  In such event, the allocation will be made
by the manager in the manner considered to be most equitable and consistent with
its fiduciary obligations to all such fiduciary accounts, including the funds.

PERFORMANCE ADVERTISING

FUND PERFORMANCE

     Individual fund performance may be compared to various  indices,  including
the  Standard  & Poor's 500  Index,  the  Consumer  Price  Index,  the Dow Jones
Industrial  Average and the S&P/Barra  Value (with regard to Value),  the Lipper
Equity Income Fund Index (with regard to Equity Income),  and the Morgan Stanley
REIT Index,  NAREIT Equity-Less Health Care Index , and Wilshire REIT Only Index
(with regard to the Real Estate Fund).  Fund performance also may be compared to
the rankings prepared by Lipper Analytical Services, Inc.

     The  following  table sets forth the  average  annual  total  return of the
Investor  class of the funds for the periods  indicated.  Average  annual  total
return is calculated by determining each fund's  cumulative total return for the
stated period and then computing the annual  compound  return that would produce
the  cumulative  total return if the fund's  performance  had been constant over
that period.  Cumulative total return includes all elements of return, including
reinvestment of dividends and capital gains  distributions.  Annualization  of a
fund's  return  assumes  that the  partial  year  performance  will be  constant
throughout  the period.  Actual return through the period may be greater or less
than the annualized data.

ADDITIONAL PERFORMANCE COMPARISONS

     Investors  may  judge  the  performance  of the  funds by  comparing  their
performance to the  performance of other mutual funds or mutual fund  portfolios
with comparable  investment  objectives and policies through various mutual fund
or market  indices such as the EAFE(R)  Index,  NAREIT  Equity-Less  Health Care
Index and Wilshire REIT Only Index, and those prepared by Dow Jones & Co., Inc.,
Standard & Poor's  Corporation,  Shearson Lehman Brothers,  Inc. and The Russell
2000  Index,  and  to  data  prepared  by  Lipper  Analytical  Services,   Inc.,
Morningstar,  Inc. and the Consumer Price Index. Comparisons may also be made to
indices or data published in Money, Forbes,  Barron's,  The Wall Street Journal,
The New York Times,  Business Week, Pensions and Investments,  USA Today, Realty
Stock  Review,  Changing  Times,   Institutional  Investor,  and  other  similar
publications  or  services.  In addition  to  performance  information,  general
information  about  the  funds  that  appears  in a  publication  such as  those
mentioned above or in the applicable  prospectus under the heading  "Performance
Advertising" may be included in advertisements and in reports to shareholders.

PERMISSIBLE ADVERTISING INFORMATION

     From time to time,  the funds may,  in  addition  to any other  permissible
information,  include the  following  types of  information  in  advertisements,
supplemental  sales literature and reports to  shareholders:  (1) discussions of
general economic or financial principles (such as the effects of compounding and
the benefits of dollar-cost  averaging);  (2)  discussions  of general  economic
trends; (3) presentations of statisti-

Statement of Additional Information                                           17


cal data to supplement such discussions; (4) descriptions of past or anticipated
portfolio  holdings for one or more of the funds; (5) descriptions of investment
strategies  for one or more of the funds;  (6)  descriptions  or  comparisons of
various  savings  and  investment  products  (including,  but  not  limited  to,
qualified  retirement plans and individual  stocks and bonds),  which may or may
not include the funds;  (7)  comparisons of investment  products  (including the
funds) with relevant market or industry indices or other appropriate benchmarks;
(8) discussions of fund rankings or ratings by recognized rating  organizations;
and (9) testimonials  describing the experience of persons that have invested in
one or more of the  funds.  The funds  may also  include  calculations,  such as
hypothetical   compounding  examples,  which  describe  hypothetical  investment
results in such  communications.  Such performance  examples will be based on an
express set of assumptions  and are not indicative of the  performance of any of
the funds.

DISTRIBUTION RATES

     In  its  sales  literature,  the  Real  Estate  Fund  may  also  quote  its
distribution rate along with the above described standard total return and yield
information.  The  distribution  rate is  calculated by  annualizing  the latest
distribution  and dividing the result by the offering  price per share as of the
end of the period to which the distribution  relates. A distribution can include
gross  investment  income from debt  obligations  purchased  at a premium and in
effect  include a portion of the premium paid. A  distribution  can also include
gross  short-term  capital gains without  recognition of any unrealized  capital
losses.  Further,  a distribution can include income from the sale of options by
the fund even though  such option  income is not  considered  investment  income
under generally accepted accounting principals.

     Because a distribution can include such premiums,  capital gains and option
income,  the amount of the  distribution  may be  susceptible  to control by the
manager  through  transactions  designed to  increase  the amount of such items.
Also, because the distribution rate is calculated in part by dividing the latest
distribution by net asset value ,the  distribution rate will increase as the net
asset value  declines.  A  distribution  rate can be greater than the yield rate
calculated as described above.

REDEMPTIONS IN KIND

     In order to protect the  investments  of the  remaining  shareholders,  the
funds  have  adopted  a policy  regarding  large  redemptions.  That  policy  is
described  in detail  in the  applicable  fund  prospectuses  under the  heading
"Special Requirements for Large Redemptions."

     The funds have  elected to be governed  by Rule 18f-1 under the  Investment
Company Act,  pursuant to which the funds are  obligated to redeem shares solely
in cash up to the  lesser of  $250,000  or 1% of the net  asset  value of a fund
during any 90-day  period for any one  shareholder.  Should  redemptions  by any
shareholder exceed such limitation,  the funds will have the option of redeeming
the excess in cash or in kind.  If shares are  redeemed in kind,  the  redeeming
shareholder  might incur  brokerage  costs in converting the assets to cash. The
securities  delivered  will be selected at the sole  discretion  of the manager.
Such securities will not necessarily be  representative  of the entire portfolio
and may be securities that the manager regards as least desirable. The method of
valuing  securities  used to make  redemptions  in kind  will be the same as the
method of valuing  portfolio  securities  described in each prospectus under the
heading "How Share Price is  Determined,"  and such valuation will be made as of
the same time the redemption price is determined.

HOLIDAYS

     The funds do not determine the net asset value of their shares on days when
the New York Stock  Exchange  is closed.  Currently,  the  Exchange is closed on
Saturdays and Sundays and on holidays, namely New Year's Day, Martin Luther King
Jr. Day,  Presidents' Day, Good Friday,  Memorial Day,  Independence  Day, Labor
Day, Thanksgiving and Christmas.

                         SUPPLEMENT DATED AUGUST 1, 1997
                         Prospectus dated March 1, 1997


The Board of  Directors  of the funds  offered  by this  Prospectus  unanimously
agreed to enter into an Agreement and Plan of  Reorganization  with the American
Century Government Income Trust. The Agreement provides for the consolidation of
these  funds with other  American  Century  funds that have  similar  investment

August 30, 1997.  Following the  reorganization,  shareholders of the Short-Term
Government Fund will own shares of the Adjustable Rate  Government  Fund,  which
will change its name to Short-Term  Government  Fund,  and  shareholders  of the
Intermediate-Term  Government  Fund  will own  shares  of the  Intermediate-Term
Treasury Fund, all in the same dollar amount as their shares held in the merging
funds at the close of business on the date of the merger.

INVESTMENT OBJECTIVES OF THE FUNDS

The investment  objective of each fund comprising American Century Mutual Funds,
Inc. is described  on page 2 of the  applicable  prospectus.  One feature of the
various series of shares (funds) merits further explanation. As described in the
Growth Funds Prospectus, the chief investment difference among Growth, Ultra and
Vista,  and between Select and Heritage,  is the size of the fund, which affects
the nature of the investments in the fund's  portfolio.  A smaller fund tends to
be more  responsive  to changes in the value of its  portfolio  securities.  For
example,  if a $1,000,000 fund buys $5,000 of stock which then doubles in value,
the value of the fund increases by only one-half of 1%.  However,  if a $100,000
fund buys  $5,000 of such stock  which then  doubles in value,  the value of the
fund increases by 5%, or at a rate 10 times as great.  By the same token, if the
value of such stock declines by one-half,  the small fund would decline in value
by 2.5%,  while the larger fund would decline in value by only one-half of 1% or
at a rate only one-tenth as great. Thus, a small fund with the same objective as
a large fund, and similarly  managed,  likely will have a greater  potential for
profit and for loss as well.

FUNDAMENTAL POLICIES OF THE FUNDS

In achieving its objective,  a fund must conform to certain fundamental policies
that may not be changed without shareholder approval, as follows:

SELECT,  HERITAGE,  GROWTH,  ULTRA, VISTA,  GIFTRUST,  NEW OPPORTUNITIES AND THE
EQUITY INVESTMENTS OF BALANCED

In general,  within the restrictions outlined herein, American Century has broad
powers with respect to investing funds or holding them  uninvested.  Investments
are varied  according to what is judged  advantageous  under  changing  economic
conditions. It is our policy to retain maximum flexibility in management without
restrictive  provisions  as to  the  proportion  of  one  or  another  class  of
securities  that may be held subject to the  investment  restrictions  described
below.  It is the  manager's  intention  that  each  of  these  portfolios  will
generally consist of common stocks.  However,  the manager may invest the assets
of each series in varying amounts in other instruments and in senior securities,
such as bonds, debentures,  preferred stocks and convertible issues, when such a
course  is deemed  appropriate  in order to  attempt  to  attain  its  financial
objective. Senior securities that, in the opinion of the manager, are high-grade
issues may also be purchased for defensive purposes.  [Note: The above statement
of fundamental  policy gives American Century  authority to invest in securities
other than common stocks and traditional debt and convertible issues. Though the
funds have not made such  investments  in the past,  the  manager  may invest in
master limited  partnerships  (other than real estate  partnerships) and royalty
trusts which are traded on domestic stock  exchanges when such  investments  are
deemed appropriate for the attainment of the funds' investment objectives.]

BALANCED

The manager will invest  approximately  60% of the Balanced  portfolio in common
stocks and the balance in fixed income securities.  Common stock investments are
described  above.  At least 80% of the fixed  income  assets will be invested in
securities  that are rated at the time of  purchase by a  nationally  recognized
statistical rating organization to be within the three highest  categories.  The
fund may invest in securities of the United States  government  and its agencies
and    instrumentalities,    corporate,    sovereign   government,    municipal,
mortgage-backed,  and other  asset-backed  securities.  It can be expected  that
management  will  invest  from  time  to  time  in  bonds  and  preferred  stock
convertible into common stock.

CASH RESERVE

The manager will invest the Cash Reserve portfolio in debt securities payable in
United States currency.  Such securities may be obligations issued or guaranteed
by the  United  States  government  or its  agencies  and  instrumentalities  or
obligations issued by corporations and others,  including repurchase agreements,
of such quality and with such maturities to permit Cash Reserve to be designated
as a money market fund and to enable it to maintain a stable  offering price per
share.

The fund  operates  pursuant  to a rule under the  Investment  Company  Act that
permits  valuation of portfolio  securities  on the basis of amortized  cost. As
required by the rule, the Board of Directors has 

2                                                   American Century Investments

adopted procedures designed to stabilize, to the extent reasonably possible, the
fund's price per share as computed for the purpose of sales and  redemptions  at
$1.00.  While the  day-to-day  operation  of the fund has been  delegated to the
manager,   the  quality   requirements   established  by  the  procedures  limit
investments to certain United States  dollar-denominated  instruments  which the
board of directors has  determined  present  minimal credit risks and which have
been  rated in one of the two  highest  rating  categories  as  determined  by a
nationally  recognized  statistical  rating  organization  or, in the case of an
unrated security,  of comparable  quality.  The procedures require review of the
fund's  portfolio  holdings  at such  intervals  as are  reasonable  in light of
current  market  conditions  to  determine  whether  the fund's net asset  value
calculated  by using  available  market  quotations  deviates from the per-share
value based on amortized  cost. The  procedures  also prescribe the action to be
taken if such deviation should occur.

SHORT-TERM GOVERNMENT FUND AND
INTERMEDIATE-TERM GOVERNMENT FUND

The  manager  will  invest the  portfolios  of  Short-Term  Government  Fund and
Intermediate-Term  Government  Fund in direct  obligations of the United States,
such as Treasury  bills,  Treasury  notes and U.S.  government  bonds,  that are
supported  by the full faith and credit of the United  States.  The  manager may
also invest in agencies and  instrumentalities  of the United States  government
that are established  under the authority of an act of Congress.  The securities
of some of such agencies and  instrumentalities  are supported by the full faith
and credit of the United States  Treasury;  others are supported by the right of
the issuer to borrow from the Treasury;  still others are supported  only by the
credit of the instrumentality.  Such agencies and instrumentalities include, but
are not  limited  to, the  Government  National  Mortgage  Association,  Federal
National Mortgage Association,  Federal Home Loan Mortgage Corporation,  Student
Loan Marketing Association,  Federal Farm Credit Banks, Federal Home Loan Banks,
and  Resolution  Funding  Corporation.  Purchase of such  securities may be made
outright  or on a  when-issued  basis  and may be  made  subject  to  repurchase
agreements.

LIMITED-TERM BOND, INTERMEDIATE-TERM BOND AND BENHAM BOND

The manager will invest the  portfolios of the corporate bond funds in high- and
medium-grade  debt securities  payable in United States currency.  The funds may
invest in securities  that,  at the time of purchase,  are rated by a nationally
recognized  statistical rating  organization or, if not rated, are of equivalent
investment quality as determined by the management, as follows: short-term notes
within the two highest categories; corporate, sovereign government and municipal
bonds  within the four  highest  categories;  securities  of the  United  States
government and its agencies and instrumentalities; and other types of securities
rated at  least  P-2 by  Moody's  or A-2 by S&P.  The  funds  may also  purchase
securities  under  repurchase  agreements  as  described in the  prospectus  and
purchase and sell  interest  rate futures  contracts  and related  options.  See
"Interest Rate Futures Contracts and Related Options," page 9.

LIMITED-TERM TAX-EXEMPT, INTERMEDIATE-TERM TAX-EXEMPT AND LONG-TERM TAX-EXEMPT

The manager  will invest the  tax-exempt  portfolios  in high- and  medium-grade
securities.  At  least  80% of  each  fund's  net  assets  will be  invested  in
securities  whose income is not subject to federal  income taxes,  including the
alternative minimum tax.

The two principal  classifications of tax-exempt securities are notes and bonds.
Tax-exempt notes are of short maturity, generally less than three years, and are
issued to provide for short-term  capital needs.  These include tax anticipation
notes and  revenue  anticipation  notes,  among  others,  as well as  tax-exempt
commercial  paper.   Tax-exempt  bonds,  which  meet  long-term  capital  needs,
generally have maturities longer than one year. The two categories of tax-exempt
bonds,  general  obligation  and  revenue,  may  be  held  by the  funds  in any
proportion.  General  obligation bonds are secured by the issuer's pledge of its
full faith,  credit and taxing power for the payment of principal  and interest.
Revenue bonds are payable from the revenue derived from a project or facility or
from the proceeds of a specific revenue source,  but not from the general taxing
power.  Industrial  development revenue bonds are a type of revenue bond secured
by payments  from a private  user,  and  generally  do not 

Statement of Additional Information                                            3

enjoy a call upon the  resources  of the  municipality  that  issued the bond on
behalf of the user.

The  funds  may  invest  in  fixed-,  floating-  and  variable-rate  securities.
Fixed-rate  securities pay interest at the fixed rate until maturity.  Floating-
and  variable-rate  securities  normally have a stated maturity in excess of one
year,  but may have a  provision  permitting  the  holder to demand  payment  of
principal and interest upon not more than seven days' notice.  Floating rates of
interest are tied to a percentage  of a designated  base rate,  such as rates on
Treasury  bills or the prime  rate at a major  bank,  and  change  whenever  the
designated  rate  changes.  Variable-rate  securities  provide  for  a  periodic
adjustment in the rate.

For the purpose of  determining  the maturity of an  individual  security or the
average  weighted  portfolio  maturity of one of the funds,  the  manager  shall
consider  the  maturity  to be the  shorter  of final  maturity,  the  remaining
expected  average  life of a sinking  fund  bond,  the  remaining  time  until a
mandatory put date,  the time until payment as the result of exercising a put or
demand-for-payment option, or the remaining time until the pre-refunding payment
date of a security whose  redemption on a call date in advance of final maturity
is assured through  contractual  agreement and with  high-quality  collateral in
escrow.

The funds may invest in securities that, at the time of purchase, are rated by a
nationally  recognized  statistical rating organization or, if not rated, are of
equivalent  investment  quality as  determined  by the  management,  as follows:
short-term  notes  within  the two  highest  categories,  bonds  within the four
highest categories,  and other types of securities rated at least P-2 by Moody's
or A-2 by S&P. The funds may invest more than 25% of their assets in  industrial
development revenue bonds. Each of the funds may invest in interest rate futures
contracts and related options.  See "Interest Rate Futures Contracts and Related
Options," page 9.

BENHAM BOND, LIMITED-TERM TAX-EXEMPT,
INTERMEDIATE-TERM TAX-EXEMPT AND LONG-TERM TAX-EXEMPT

Benham Bond, Limited-Term Tax-Exempt, Intermediate-Term Tax-Exempt and Long-Term
Tax-Exempt (the funds) may buy and sell interest rate futures contracts relating
to debt securities  ("debt futures," i.e.,  futures relating to debt securities,
and "bond index futures," i.e.,  futures  relating to indexes on types or groups
of bonds)  and write and buy put and call  options  relating  to  interest  rate
futures  contracts  for the purpose of hedging  against (i) declines or possible
declines in the market value of debt securities or (ii) inability to participate
in advances in the market values of debt  securities at times when the funds are
not fully  invested in long-term debt  securities;  provided that, the funds may
not  purchase  or sell  futures  contracts  or related  options  if  immediately
thereafter the sum of the amount of margin deposits on a fund's existing futures
positions  and premiums  paid for related  options would exceed 5% of the fund's
assets.

ADDITIONAL INVESTMENT RESTRICTIONS

Additional  fundamental  policies  that may be  changed  only  with  shareholder
approval provide as follows:

(1) The funds shall not issue senior  securities,  except as permitted under the
Investment Company Act of 1940.

(2) The funds shall not borrow money, except that the funds may borrow money for
temporary or emergency  purposes (not for leveraging or investment) in an amount
not exceeding  331/3% of a fund's total assets  (including the amount  borrowed)
less liabilities (other than borrowings).

(3) The  funds  shall  not lend any  security  or make any  other  loan if, as a
result,  more  than  331/3%  of a  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) The funds shall not concentrate  their  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).

(5) The funds shall not purchase or sell real estate unless acquired as a result
of ownership of securities or other instruments. This policy shall not prevent a
fund from investment in securities or other instruments backed by real

4                                                   American Century Investments

estate or securities of companies that deal in real estate or are engaged in the
real estate business.

(6) The funds shall not act as an  underwriter  of securities  issued by others,
except to the extent that a fund may be  considered  an  underwriter  within the
meaning  of  the  Securities  Act  of  1933  in the  disposition  of  restricted
securities.

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

(8) The  funds  shall  not  invest  for  purposes  of  exercising  control  over
management.

In addition,  the funds have adopted the  following  non-fundamental  investment
restrictions:

(1) As an  operating  policy,  a fund shall not purchase  additional  investment
securities  at any time during  which  outstanding  borrowings  exceed 5% of the
total assets of the fund.

(2) As an operating policy, a fund may not purchase any security or enter into a
repurchase  agreement if, as a result,  more than 15% of its net assets (10% for
money market funds) 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.

(3) As an operating  policy, a fund 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  transaction in futures  contracts and
options are not deemed to constitute selling securities short.

(4) As an  operating  policy,  a fund shall not purchase  securities  on margin,
except that a 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.

The  Investment  Company  Act  imposes  certain  additional   restrictions  upon
acquisition  by the  corporation  of securities  issued by insurance  companies,
brokers,  dealers,  underwriters or investment  advisers,  and upon transactions
with  affiliated  persons as therein  defined.  It also  defines and forbids the
creation of cross and circular  ownership.  Neither the  Securities and Exchange
Commission  nor any other agency of the federal  government  participates  in or
supervises the corporation's management or its investment practices or policies.

The Investment Company Act also provides that the funds may not invest more than
25% of their assets in the securities of issuers  engaged in a single  industry.
In determining industry groups for purposes of this standard, the Securities and
Exchange Commission  ordinarily uses the Standard Industry  Classification codes
developed by the United States Office of Management and Budget.  In the interest
of ensuring adequate  diversification,  the funds monitor industry concentration
using a more  restrictive  list of industry groups than that  recommended by the
SEC. The funds believe that these  classifications are reasonable and are not so
broad that the primary  economic  characteristics  of the  companies in a single
class  are  materially   different.   The  use  of  these  restrictive  industry
classifications may, however, cause the funds to forego investment possibilities
which may otherwise be available to them under the Investment Company Act.

Neither  the SEC  nor any  other  agency  of the  federal  or  state  government
participates in or supervise the funds' management or their investment practices
or policies.

FORWARD CURRENCY EXCHANGE CONTRACTS

The funds conduct their foreign currency exchange  transactions either on a spot
(i.e.,  cash) basis at the spot rate prevailing in the foreign currency exchange
market, or through entering into forward foreign currency exchange  contracts to
purchase or sell foreign currencies.

The funds expect to use forward contracts under two circumstances:

(1) When the  manager  wishes to "lock in" the U.S.  dollar  price of a security
when a fund is  pur-

Statement of Additional Information                                            5

chasing or selling a security denominated in a foreign currency,  the fund would
be able to enter into a forward contract to do so;

(2) When the manager believes that the currency of a particular  foreign country
may suffer a substantial  decline against the U.S.  dollar, a fund would be able
to enter  into a forward  contract  to sell  foreign  currency  for a fixed U.S.
dollar  amount  approximating  the value of some or all of its fund's  portfolio
securities  either  denominated  in,  or whose  value is tied to,  such  foreign
currency.

As to the first  circumstance,  when a fund enters into a trade for the purchase
or sale of a security denominated in a foreign currency,  it may be desirable to
establish (lock in) the U.S.  dollar cost or proceeds.  By entering into forward
contracts  in U.S.  dollars  for the  purchase  or  sale of a  foreign  currency
involved in an underlying security transaction, the fund will be able to protect
itself against a possible loss between trade and settlement dates resulting from
the adverse change in the  relationship  between the U.S.  dollar at the subject
foreign currency.

Under the second circumstance,  when the manager believes that the currency of a
particular country may suffer a substantial decline relative to the U.S. dollar,
a fund could enter into a foreign contract to sell for a fixed dollar amount the
amount  in  foreign  currencies  approximating  the  value of some or all of its
portfolio  securities  either  denominated  in, or whose  value is tied to, such
foreign currency.  The fund will place cash or high-grade liquid securities in a
separate  account  with its  custodian  in an  amount  sufficient  to cover  its
obligation  under the  contract.  If the value of the  securities  placed in the
separate account  declines,  additional cash or securities will be placed in the
account on a daily basis so that the value of the  account  equals the amount of
the fund's commitments with respect to such contracts.

The  precise  matching  of  forward  contracts  in the  amounts  and  values  of
securities  involved  would not generally be possible since the future values of
such foreign  currencies will change as a consequence of market movements in the
values of those securities between the date the forward contract is entered into
and the date it matures.  Predicting  short-term  currency  market  movements is
extremely difficult, and the successful execution of short-term hedging strategy
is highly uncertain. The manager does not intend to enter into such contracts on
a regular basis.  Normally,  consideration of the prospect for currency parities
will be incorporated into the long-term  investment  decisions made with respect
to overall diversification strategies.  However, the manager believes that it is
important  to have  flexibility  to enter into such  forward  contracts  when it
determines that a fund's best interests may be served.

Generally,  a fund will not enter into a forward contract with a term of greater
than one year. At the maturity of the forward contract, the fund may either sell
the  portfolio  security and make  delivery of the foreign  currency,  or it may
retain the security and terminate the obligation to deliver the foreign currency
by purchasing an  "offsetting"  forward  contract with the same currency  trader
obligating  the fund to purchase,  on the same maturity date, the same amount of
the foreign currency.

It is  impossible  to  forecast  with  absolute  precision  the market  value of
portfolio securities at the expiration of the forward contract.  Accordingly, it
may be necessary for a fund to purchase  additional foreign currency on the spot
market  (and bear the  expense  of such  purchase)  if the  market  value of the
security is less than the amount of foreign  currency  the fund is  obligated to
deliver and if a decision is made to sell the security and make  delivery of the
foreign currency the fund is obligated to deliver.

AN EXPLANATION OF FIXED INCOME SECURITIES RATINGS

As described in the  applicable  prospectus,  certain of the funds will have, at
any given time,  investments  in fixed  income  securities.  Those  investments,
however,  are subject to certain  credit quality  restrictions,  as noted in the
applicable  prospectus.  The following is a description of the rating categories
referenced in the prospectus fund disclosure.

The  following  summarizes  the highest  four  ratings used by Standard & Poor's
Corporation for bonds:

AAA - This  is the  highest  rating  assigned  by S&P to a debt  obligation  and
indicates an extremely strong capacity to pay interest and repay principal.

AA - Debt rated AA is considered to have a very strong  capacity to pay interest
and repay principal and differs from AAA issues only in a small degree.

6                                                   American Century Investments

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.

To  provide  more  detailed  indications  of credit  quality,  the AA, A and BBB
ratings may be modified by the addition of a plus or minus sign to show relative
standing within these major rating categories.

Commercial  paper rated A-1 by S&P indicates that the degree of safety regarding
timely payment is strong.  Those issues  determined to possess  extremely strong
safety  characteristics  are  denoted  A-1+.  Capacity  for  timely  payment  on
commercial paper rated A-2 is satisfactory, but the relative degree of safety is
not as high as for issues designated A-1.

The rating SP-1 is the highest  rating  assigned by S&P to  municipal  notes and
indicates  very strong or strong  capacity to pay principal and interest.  Those
issues determined to possess  overwhelming  safety  characteristics  are given a
plus (+) designation.

The  following  summarizes  the highest four  ratings used by Moody's  Investors
Service, Inc. for bonds:

Aaa - Bonds that are rated Aaa are judged to be of the best quality.  They carry
the smallest  degree of investment  risk and are generally  referred to as "gilt
edge."  Interest  payments  are  protected  by a large,  or by an  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 comprise 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 which make
the long-term risks appear somewhat larger than in Aaa securities.

A - Debt which is rated A possesses many favorable investment  attributes and is
to be considered as an upper medium-grade obligation. Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

Baa - Debt which is rated Baa is considered as a medium-grade obligation,  i.e.,
it is  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 debt lacks outstanding  investment  characteristics  and in
fact has speculative characteristics as well.

Moody's applies numerical modifiers (1, 2 and 3) with respect to bonds rated Aa,
A and Baa.  The  modifier 1  indicates  that the bond being  rated  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 bond ranks in the lower end of
its generic rating category.

The rating  Prime-1 or P-1 is the highest  commercial  paper rating  assigned by
Moody's.   Issuers  rated  Prime-1  (or  related  supporting  institutions)  are
considered to have a superior  capacity for  repayment of short-term  promissory
obligations.  Issuers rated Prime-2 or P-2 (or related supporting  institutions)
are considered to have a strong capacity for repayment of short-term  promissory
obligations.  This will normally be evidenced by many of the  characteristics of
issuers  rated  Prime-1 but to a lesser  degree.  Earnings  trends and  coverage
ratios,  while  sound,  will  be  more  subject  to  variation.   Capitalization
characteristics,  while  still  appropriated,  may be more  affected by external
conditions. Ample alternate liquidity is maintained.

The following summarized the highest rating used by Moody's for short-term notes
and variable rate demand obligations:

MIG-1;  VMIG-1 - Obligations bearing these designations are of the best quality,
enjoying strong protection by established cash flows, superior liquidity support
or demonstrated broad-based access to the market for refinancing.

SHORT SALES

The common  stock funds and the  Balanced  Fund may engage in short sales if, at
the time of the short  sale,  the fund owns or has the right to acquire an equal
amount of the security being sold short.

In a short sale, the seller does not immediately deliver the securities sold and
is said to have a short position in those securities  until delivery occurs.  To
make delivery to the  purchaser,  the executing  broker  borrows the  securities
being  sold  short  on  behalf  of the  seller.  While  the  short  position  is
maintained,  the seller  collateralizes its obligation to deliver the securities
sold  short in an  amount  equal  to the  proceeds  of the  short  sale  plus an
additional  margin amount  established  by the Board of Governors of the Federal
Reserve.  If a fund  engages in a short sale,  the  collateral  account  will be
maintained by the fund's custodian.  While the short sale is open, the fund will
maintain in a segregated  custodial account an amount of securities  convertible
into, or  exchangeable  for, such equivalent  securities at no additional  cost.
These securities would constitute the fund's long position.

A fund may make a short  sale,  as  described  above,  when it wants to sell the
security  it owns at a  current  attractive  price,  but  also  wishes  to defer
recognition  of gain or loss for federal income tax purposes and for purposes of
satisfying certain tests applicable to regulated  investment companies under the
Internal  Revenue  Code.  In such a case,  any future  losses in the fund's long
position should be reduced by a gain in the short position.  The extent to which
such gains or losses are reduced  would  depend upon the amount of the  security
sold  short  relative  to the  amount  the  fund  owns.  There  will be  certain
additional  transaction  costs  associated  with short sales,  but the fund will
endeavor  to offset  these costs with  income  from the  investment  of the cash
proceeds of short sales.

PORTFOLIO TURNOVER

The portfolio turnover rates of the funds are shown in the Financial  Highlights
table in the prospectuses.

With  respect to each  series of shares,  the  manager  will  purchase  and sell
securities  without regard to the length of time the security has been held and,
accordingly,  it can be  expected  that the rate of  portfolio  turnover  may be
substantial.

The funds intend to purchase a given security  whenever the manager  believes it
will contribute to the stated objective of the series, even if the same security
has only recently been sold. In selling a given  security,  the manager keeps in
mind that (1) profits from sales of securities  held less than three months must
be limited in order to meet the  requirements  of  Subchapter  M of the Internal
Revenue Code, and (2) profits from sales of securities are taxed to shareholders
as ordinary income. Subject to those considerations, the corporation will sell a
given  security,  no  matter  for how long or for how short a period it has been
held in the portfolio, and no matter whether the sale is at a gain or at a loss,
if the manager  believes that it is not fulfilling its purpose,  either because,
among other things, it did not live up to the manager's expectations, or because
it may be replaced with another security holding greater promise,  or because it
has reached its optimum  potential,  or because of a change in the circumstances
of a  particular  company or  industry  or in general  economic  conditions,  or
because of some combination of such reasons.

When a general decline in security  prices is anticipated,  the equity funds may
decrease or eliminate  entirely  their equity  positions and increase their cash
positions, and when a rise in price levels is anticipated,  the equity funds may
increase  their equity  positions and decrease  their cash  positions.  However,
these funds have followed the practice of remaining  essentially  fully invested
in equity securities.

Since  investment  decisions are based on the  anticipated  contribution  of the
security in question to the corporation's objectives,  the manager believes that
the rate of  portfolio  turnover is  irrelevant  when it believes a change is in
order to  achieve  those  objectives,  and the  corporation's  annual  portfolio
turnover  rate  cannot  be  anticipated  and  may be  comparatively  high.  This
disclosure regarding portfolio turnover is a statement of fundamental policy and
may be changed only by a vote of the shareholders.

Since the manager does not take  portfolio  turnover rate into account in making
investment  decisions,  (1) the manager has no  intention of  accomplishing  any
particular  rate  of  portfolio  turnover,  whether  high  or  low,  and (2) the
portfolio turnover rates in the past

8                                                   American Century Investments

should not be considered as a representation of the rates which will be attained
in the future.

INTEREST RATE FUTURES CONTRACTS AND RELATED
OPTIONS

Limited-Term Bond, Intermediate-Term Bond, Benham Bond, Limited-Term Tax-Exempt,
Intermediate-Term  Tax-Exempt and Long-Term  Tax-Exempt  (the funds) may buy and
sell  interest  rate  futures  contracts  relating  to  debt  securities  ("debt
futures," i.e.,  futures relating to debt securities,  and "bond index futures,"
i.e., futures relating to indexes on types or groups of bonds) and write and buy
put and call options relating to interest rate futures contracts.

A fund will not  purchase or sell  futures  contracts  and  options  thereon for
speculative  purposes but rather only for the purpose of hedging against changes
in the market value of its  portfolio  securities or changes in the market value
of securities  that  American  Century  Investment  Management,  Inc.  (manager)
anticipates  that it may wish to include in the  portfolio of a fund. A fund may
sell a future  or write a call or  purchase  a put on a  future  if the  manager
anticipates  that a general market or market sector decline may adversely affect
the market value of any or all of the fund's  holdings.  A fund may buy a future
or  purchase  a call or sell a put on a  future  if the  manager  anticipates  a
significant  market advance in the type of securities it intends to purchase for
the fund's  portfolio at a time when the fund is not invested in debt securities
to the extent permitted by its investment policies. A fund may purchase a future
or a  call  option  thereon  as a  temporary  substitute  for  the  purchase  of
individual  securities  which may then be  purchased in an orderly  fashion.  As
securities are purchased, corresponding futures positions would be terminated by
offsetting sales.

The "sale" of a debt future means the  acquisition  by the fund of an obligation
to deliver the related debt securities (i.e.,  those called for by the contract)
at a specified  price on a specified date. The "purchase" of a debt future means
the  acquisition  by the fund of an  obligation  to  acquire  the  related  debt
securities at a specified  time on a specified  date. The "sale" of a bond index
future means the  acquisition  by the fund of an obligation to deliver an amount
of cash equal to a specified  dollar  amount  times the  difference  between the
index value at the close of the last  trading day of the future and the price at
which the future is originally  struck. No physical delivery of the bonds making
up the index is expected to be made. The "purchase" of a bond index future means
the  acquisition by the fund of an obligation to take delivery of such an amount
of cash.

Unlike when the fund  purchases or sells a bond, no price is paid or received by
the fund upon the  purchase or sale of the future.  Initially,  the fund will be
required to deposit an amount of cash or securities equal to a varying specified
percentage of the contract amount.  This amount is known as initial margin. Cash
held in the margin account is not income producing.  Subsequent payments, called
variation margin,  to and from the broker,  will be made on a daily basis as the
price of the underlying debt securities or index  fluctuates,  making the future
more or less  valuable,  a  process  known  as mark to the  market.  Changes  in
variation margin are recorded by the fund as unrealized gains or losses.  At any
time prior to expiration of the future, the fund may elect to close the position
by taking an opposite  position  that will operate to terminate  its position in
the future. A final  determination of variation margin is then made;  additional
cash is required  to be paid by or released to the fund and the fund  realizes a
loss or a gain.

When a fund  writes an option on a futures  contract  it becomes  obligated,  in
return for the premium  paid,  to assume a position  in a futures  contract at a
specified  exercise  price at any time during the term of the option.  If a fund
has  written a call,  it  becomes  obligated  to assume a "long"  position  in a
futures  contract,  which  means that it is  required  to take  delivery  of the
underlying  securities.  If it has  written a put, it is  obligated  to assume a
"short"  position  in a futures  contract,  which  means that it is  required to
deliver  the  underlying  securities.  When the fund  purchases  an  option on a
futures contract it acquires a right in return for the premium it pays to assume
a position in a futures contract.

If a fund writes an option on a futures  contract it will be required to deposit
initial  and  variation  margin  pursuant  to  requirements   similar  to  those
applicable to futures contracts. Premiums received from the writing of an option
on a future are included in the

Statement of Additional Information                                            9

initial margin deposit.

For options sold, the fund will segregate cash or  high-quality  debt securities
equal to the value of  securities  underlying  the  option  unless the option is
otherwise covered.

A fund will deposit in a segregated account with its custodian bank high-quality
debt  obligations  maturing in one year or less,  or cash, 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.

Changes  in  variation  margin are  recorded  by a fund as  unrealized  gains or
losses.  Initial margin payments will be deposited in the fund's  custodian bank
in an account  registered  in the  broker's  name;  access to the assets in that
account may be made by the broker only under specified  conditions.  At any time
prior to expiration of a futures contract or an option thereon, a fund may elect
to close the  position  by taking an  opposite  position  that will  operate  to
terminate its position in the futures contract or option. A final  determination
of variation margin is made at that time; additional cash is required to be paid
by or released to it and it realizes a loss or gain.

Although  futures  contracts  by their  terms  call for the actual  delivery  or
acquisition of the underlying  securities or cash, in most cases the contractual
obligation is so fulfilled without having to make or take delivery. The funds do
not  intend  to  make  or  take  delivery  of  the  underlying  obligation.  All
transactions  in futures  contracts  and  options  thereon  are made,  offset or
fulfilled  through a  clearinghouse  associated  with the  exchange on which the
instruments  are  traded.  Although  the funds  intend  to buy and sell  futures
contracts  only on  exchanges  where  there  appears  to be an active  secondary
market,  there is no assurance that a liquid secondary market will exist for any
particular  future at any particular time. In such event, it may not be possible
to close a futures contract position.  Similar market liquidity risks occur with
respect to options.

The use of futures  contracts and options  thereon to attempt to protect against
the market risk of a decline in the value of portfolio securities is referred to
as having a "short futures  position." The use of futures  contracts and options
thereon to attempt to protect  against  the market risk that a fund might not be
fully invested at a time when the value of the securities in which it invests is
increasing  is referred to as having a "long futures  position."  The funds must
operate within certain  restrictions  as to long and short  positions in futures
contracts and options  thereon under a rule (CFTC Rule) adopted by the Commodity
Futures Trading  Commission under the Commodity  Exchange Act to be eligible for
the exclusion  provided by the CFTC Rule from  registration by the fund with the
CFTC as a  "commodity  pool  operator"  (as  defined  under the  CEA),  and must
represent to the CFTC that it will operate within such restrictions. Under these
restrictions  a fund will not, as to any  positions,  whether  long,  short or a
combination thereof,  enter into futures contracts and options thereon for which
the aggregate initial margins and premiums exceed 5% of the fair market value of
the fund's  assets after taking into  account  unrealized  profits and losses on
options  the  fund  has  entered  into;  in  the  case  of  an  option  that  is
"in-the-money"  (as  defined  under the CEA),  the  in-the-money  amount  may be
excluded in computing such 5%. (In general,  a call option on a futures contract
is in-the-money if the value of the future exceeds the strike,  i.e.,  exercise,
price of the call;  a put option on a futures  contract is  in-the-money  if the
value of the futures  contract that is the subject of the put is exceeded by the
strike price of the put.) Under the restrictions,  a fund also must, as to short
positions,  use  futures  contracts  and  options  thereon  solely for bona fide
hedging  purposes  within the  meaning and intent of the  applicable  provisions
under  the  CEA.  As to its  long  positions  that  are used as part of a fund's
portfolio strategy and are incidental to the fund's activities in the underlying
cash market, the "underlying  commodity value" (see below) of the fund's futures
contract and options thereon must not exceed the sum of (i) cash set aside in an
identifiable   manner,  or  short-term  U.S.  debt  obligations  or  other  U.S.
dollar-denominated,  high-quality,  short-term  money market  instruments so set
aside,  plus any funds  deposited as margin;  (ii) cash  proceeds  from existing
investments  due in 30 days;  and  (iii)  accrued  profits  held at the  futures
commission  merchant.  (There are described above the segregated accounts that a
fund must maintain with its custodian bank as to its options and

10                                                  American Century Investments

futures  contracts   activities  due  to  Securities  and  Exchange   Commission
requirements.  The fund will, as to its long positions,  be required to abide by
the  more  restrictive  of  these  SEC and CFTC  requirements.)  The  underlying
commodity  value of a futures  contract  is  computed  by  multiplying  the size
(dollar  amount) of the futures  contract by the daily  settlement  price of the
futures  contract.  For an  option  on a  futures  contract,  that  value is the
underlying commodity value of the future underlying the option.

Since futures contracts and options thereon can replicate  movements in the cash
markets  for the  securities  in which a fund  invests  without  the large  cash
investments  required  for dealing in such  markets,  they may subject a fund to
greater and more volatile risks than might  otherwise be the case. The principal
risks related to the use of such instruments are (i) 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;  (ii)  possible  lack of a liquid  secondary  market for  closing out
futures or options positions; (iii) the need for additional portfolio management
skills and techniques;  (iv) losses due to unanticipated market price movements;
and (v) the  bankruptcy  or failure  of a futures  commission  merchant  holding
margin deposits made by the funds and the funds'  inability to obtain  repayment
of all or part of such  deposits.  For a hedge to be completely  effective,  the
price  change of the hedging  instrument  should  equal the price  change of the
security 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 manager will attempt to create a closely  correlated
hedge,  but hedging  activity may not be completely  successful  in  eliminating
market value  fluctuation.  The ordinary  spreads between prices in the cash and
futures  markets,  due to the  differences in the natures of those markets,  are
subject to the  following  factors  which may  create  distortions.  First,  all
participants in the futures market are subject to margin deposit and maintenance
requirements.  Rather  than  meeting  additional  margin  deposit  requirements,
investors may close futures  contracts  through  offsetting  transactions  which
could  distort the normal  relationship  between  the cash and futures  markets.
Second,  the liquidity of the futures  market depends on  participants  entering
into  off-setting  transactions  rather than making or taking  delivery.  To the
extent  participants  decide to make or take delivery,  liquidity in the futures
market could be reduced,  thus producing  distortion.  Third,  from the point of
view of  speculators,  the deposit  requirements  in the futures market are less
onerous than margin requirements in the securities market. Therefore,  increased
participation  by speculators in the futures  market may cause  temporary  price
distortions. Due to the possibility of distortion, a correct forecast of general
interest 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.

The risk of imperfect correlation between movements in the price of a bond index
future and movements in the price of the securities  that are the subject of the
hedge  increases as the  composition  of a fund's  portfolio  diverges  from the
securities  included in the applicable index. The price of the bond index future
may move more than or less than the price of the securities being hedged. If the
price of the bond index future moves less than the price of the securities  that
are the subject of the hedge, the hedge will not be fully effective,  but if the
price of the securities being hedged has moved in an unfavorable direction,  the
fund  would be in a better  position  than if it had not  hedged at all.  If the
price of the securities  being hedged has moved in a favorable  direction,  this
advantage will be partially offset by the futures contract.  If the price of the
futures  contract  moves  more  than the  price  of the  security,  a fund  will
experience  either a loss or a gain on the  futures  contract  that  will not be
completely  offset  by  movements  in the price of the  securities  that are the
subject of the hedge.  To compensate for the imperfect  correlation of movements
in the price of the  securities  being hedged and  movements in the price of the
bond  index  futures,  a fund may buy or sell bond  index  futures  in a greater
dollar  amount  than  the  dollar  amount  of  securities  being  hedged  if the
historical volatility of the prices of such securities being hedged is less than
the historical  volatility of the bond index. It is also possible that,  where a
fund has sold futures contracts to hedge its 

Statement of Additional Information                                          11

securities against a decline in the market, the market may advance and the value
of securities held in the portfolio may decline. If this occurred,  a fund would
lose money on the futures contract and also experience a decline in value in its
portfolio securities. However, while this could occur for a brief period or to a
very small degree,  over time the value of a portfolio of debt  securities  will
tend to move in the same  direction as the market indexes upon which the futures
contracts are based.

Where bond index futures are  purchased to hedge against a possible  increase in
the price of bonds before a fund is able to invest in  securities  in an orderly
fashion,  it is possible that the market may decline  instead;  if the fund then
concludes  not to invest in  securities  at that time  because  of concern as to
possible further market decline or for other reasons,  it will realize a loss on
the  futures  contract  that is not  offset by a  reduction  in the price of the
securities it had anticipated purchasing.

The risks of  investment  in options on bond indexes may be greater than options
on securities. Because exercises of bond index options are settled in cash, when
a fund  writes a call on a bond  index it  cannot  provide  in  advance  for its
potential  settlement  obligations  by  acquiring  and  holding  the  underlying
securities.  A fund can  offset  some of the  risk of its  writing  position  by
holding a portfolio of bonds similar to those on which the  underlying  index is
based.  However,  a fund  cannot,  as a  practical  matter,  acquire  and hold a
portfolio containing exactly the same securities as the underlying index and, as
a result,  bears a risk that the value of the securities held will vary from the
value of the index.  Even if a fund  could  assemble a  portfolio  that  exactly
reproduced the composition of the underlying  index, it still would not be fully
covered from a risk standpoint  because of the "timing risk" inherent in writing
index  options.  When an index option is exercised,  the amount of cash that the
holder is  entitled  to receive is  determined  by the  difference  between  the
exercise  price  and the  closing  index  level on the date  when the  option is
exercised.  As with other kinds of options, a fund, as the call writer, will not
learn that it has been assigned until the next business day at the earliest. The
time lag between  exercise and notice of assignment poses no risk for the writer
of a covered call on a specific  underlying security because there, the writer's
obligation is to deliver the underlying  security,  not to pay its value as of a
fixed  time in the  past.  So long as the  writer  already  owns the  underlying
security, it can satisfy its settlement obligations by simply delivering it, and
the risk that its value may have  declined  since the exercise  date is borne by
the exercising  holder.  In contrast,  even if the writer of an index call holds
securities that exactly match the  composition of the underlying  index, it will
not be able to satisfy its assignment obligations by delivering those securities
against payment of the exercise price.  Instead, it will be required to pay cash
in an amount based on the closing index value of the exercise  date;  and by the
time it learns that it has been  assigned,  the index may have  declined  with a
corresponding  decline in the value of its  portfolio.  This "timing risk" is an
inherent  limitation  on the  ability of index call  writers to cover their risk
exposure by holding securities positions.

If a fund has  purchased  an index  option and  exercises  it before the closing
index  value for that day is  available,  it runs the risk that the level of the
underlying index may subsequently  change. If such a change causes the exercised
option to fall  out-of-the-money,  the fund  exercising  the option must pay the
difference  between the closing index value and the exercise price of the option
(times the applicable multiplier) to the assigned writer.

MUNICIPAL LEASES

The tax-exempt funds may invest in municipal lease  obligations and certificates
of participation in such obligations (collectively,  lease obligations). A lease
obligation  does not  constitute a general  obligation of the  municipality  for
which the municipality's taxing power is pledged,  although the lease obligation
is ordinarily backed by the  municipality's  covenant to budget for the payments
due under the lease obligation.

Certain lease obligations contain "non-appropriation" clauses which provide that
the municipality  has no obligation to make lease obligation  payments in future
years unless money is appropriated for such purpose on a yearly basis.  Although
"non-appropriation"  lease  obligations  are  secured  by the  leased  property,
disposition of the property in the event of foreclosure  might prove  difficult.
In evaluating a potential investment in such a lease obligation, management

12                                                  American Century Investments

will  consider:  (i)  the  credit  quality  of the  obligor,  (ii)  whether  the
underlying property is essential to a governmental  function,  and (iii) whether
the  lease   obligation   contains   covenants   prohibiting  the  obligor  from
substituting  similar property if the obligor fails to make  appropriations  for
the lease obligation.

Municipal  lease  obligations  may be determined to be liquid in accordance with
the  guidelines  established  by the funds' board of  directors  for purposes of
complying with the funds' investment restrictions.  In determining the liquidity
of a lease  obligation,  the manager will consider:  (1) the frequency of trades
and  quotes  for the lease  obligation,  (2) the  number of  dealers  willing to
purchase  or sell  the  lease  obligation  and the  number  of  other  potential
purchasers,  (3) dealer  undertakings to make a market in the lease  obligation,
(4) the nature of the marketplace  trades,  including the time needed to dispose
of the lease obligation,  the method of soliciting  offers, and the mechanics of
transfer,  (5) whether the lease obligation is of a size that will be attractive
to  institutional  investors,  (6)  whether  the  lease  obligation  contains  a
non-appropriation  clause and the likelihood  that the obligor will fail to make
an  appropriation  therefore,  and (7) such  other  factors as the  manager  may
determine to be relevant to such determination.

The Board of Directors has established four standing  committees,  the Executive
Committee,  the Audit  Committee,  the  Compliance  Committee and the Nominating
Committee.

Messrs.  Stowers Jr.,  Stowers  III,  and  Lundgaard  constitute  the  Executive
Committee of the Board of Directors. The committee performs the functions of the
Board of Directors between meetings of the Board,  subject to the limitations on
its power set out in the  Maryland  General  Corporation  Law,  and  except  for
matters  required  by the  Investment  Company Act to be acted upon by the whole
Board.

Messrs. Lundgaard (chairman), Doering and Hock and Ms. Strandjord constitute the
Audit Committee.  The functions of the Audit Committee include  recommending the
engagement of the funds' independent accountants, reviewing the arrangements for
and  scope of the  annual  audit,  reviewing  comments  made by the  independent
accountants with respect to internal  controls and the  considerations  given or
the  corrective  action taken by  management,  and reviewing  nonaudit  services
provided by the independent accountants.

Messrs. Brown (chairman),  Pratt and Silver constitute the Compliance Committee.
The functions of the Compliance  Committee  include reviewing the results of the
funds' compliance testing program,  reviewing quarterly reports from the manager
to  the  Board  regarding   various   compliance   matters  and  monitoring  the
implementation of the funds' Code of Ethics, including violations thereof.

The  Nominating  Committee  has as its  principal  role  the  consideration  and
recommendation  of  individuals  for  nomination  as  directors.  The  names  of
potential  director  candidates  are drawn from a number of  sources,  including
recommendations  from members of the Board,  management and  shareholders.  This
committee  also reviews and makes  recommendations  to the Board with respect to
the composition of Board committees and other Board-related  matters,  including
its   organization,   size,   composition,   responsibilities,   functions   and
compensation.  The  members  of  the  nominating  committee  are  Messrs.  Pratt
(Chairman), Lundgaard and Stowers III.

The Directors of the corporation also serve as Directors for other funds advised
by the manager.  Each Director who is not an  "interested  person" as defined in
the Investment  Company Act receives for service as a member of the Board of all
Twentieth Century investment  companies an annual director's fee of $44,000, and
an  additional  fee of $1,000 per regular  Board  meeting  attended and $500 per
special  Board  meeting and  committee  meeting  attended.  In  addition,  those
Directors who are not "interested  persons" and serve as chairman of a committee
of the Board of Directors receive an additional $2,000 for such services.  These
fees and  expenses are divided  among the six  investment  companies  based upon
their relative net assets.  Under the terms of the management agreement with the
manager, the funds are responsible for paying such fees and expenses.  Set forth
below is the aggregate  compensation paid for the periods indicated by the funds
and by the American  Century  family of funds as a whole to each Director who is
not an "interested person" as defined in the Investment Company Act.

1Includes  compensation  actually paid by the corporation during the fiscal year
ended October 31, 1996.

2Includes  compensation  paid by the fifteen  investment  company members of the
American Century family of funds for the calendar year ended December 31, 1996.

3Del Hock replaced Jack Urie as an independent  director  effective  October 31,
1996.

The  corporation  has  adopted  the  American   Century  Mutual  Funds  Deferred
Compensation   Plan  for   Non-Interested   Directors.   Under  the  Plan,   the
non-interested person Directors may defer receipt of all or any part of the fees
to be paid to them for serv-

14                                                  American Century Investments

ing as Directors of the corporation.

Under the Plan, all deferred fees are credited to an account  established in the
name of the  participating  Directors.  The amounts credited to the account then
increase or decrease,  as the case may be, in accordance with the performance of
one or more of the American Century funds that are selected by the participating
Director.  The account  balance  continues to fluctuate in  accordance  with the
performance  of the  selected  fund or funds until final  payment of all amounts
credited to the account.  Directors are allowed to change their  designation  of
mutual funds from time to time.

No  deferred  fees are  payable  until  such  time as a  participating  Director
resigns,  retires or otherwise  ceases to be a member of the Board of Directors.
Directors may receive deferred fee account balances either in a lump sum payment
or in substantially  equal installment  payments to be made over a period not to
exceed 10 years.  Upon the  death of a  Director,  all  remaining  deferred  fee
account  balances are paid to the  Director's  beneficiary  or, if none,  to the
Director's estate.

The  Plan  is an  unfunded  plan  and,  accordingly,  American  Century  has  no
obligation to segregate  assets to secure or fund the deferred  fees. The rights
of Directors to receive their deferred fee account  balances are the same as the
rights of a  general  unsecured  creditor  of the  corporation.  The Plan may be
terminated  at any  time  by  the  administrative  committee  of  the  Plan.  If
terminated, all deferred fee account balances will be paid in a lump sum.

No deferred fees were paid to any participating  Directors under the Plan during
the fiscal year ended October 31, 1995.

Those  Directors  who are  "interested  persons,"  as defined in the  Investment
Company Act,  receive no fee as such for serving as a Director.  The salaries of
such individuals, who are also officers of the funds, are paid by the manager.

Statement of Additional Information                                           15

The Advisor  Class of Ultra and Vista  commenced  operations on October 2, 1996.
The  management  fees shown above include $7,146 paid on Advisor Class shares of
Ultra and  $3,127  paid on Advisor  Class  shares of Vista for the 29 day period
ended October 31, 1996.

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 (i) the funds'
Board of Directors,  or by the vote of a majority of the  outstanding  votes (as
defined in the  Investment  Company Act),  and (ii) by the vote of a majority of
the  Directors of the funds 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 funds'  Board of  Directors,  or by a vote of a
majority of the funds' 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
funds or its  shareholders  for  anything  other than willful  misfeasance,  bad
faith, gross negligence or reckless disregard of its obligations or duties.

The  management  agreement  also  provides  that the manager  and its  officers,
directors 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 one or more funds and also for other
clients  advised by the manager.  Investment  decisions  for the funds 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 or series 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 a fund.

The manager may  aggregate  purchase and sale orders of the funds with  purchase
and sale  orders  of its  other  clients  when the  manager  believes  that such
aggregation  provides  the best  execution  for the funds.  The funds'  Board of
Directors has approved the policy of the manager with respect to the aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the funds  participate 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  funds  unless  it
believes such  aggregation is consistent with its duty to seek best execution on
behalf  of the  funds and the terms of the  management  agreement.  The  manager
receives  no  additional  compensation  or  remuneration  as a  result  of  such
aggregation.

On January  31,  1997,  the manager  was acting as an  investment  advisor to 12
institutional  accounts with an aggregate value of  $498,426,343.  While each of
these clients has unique investment  restrictions and guidelines,  some have all
elected to have their portfolios managed in a manner similar to the portfolio of
either Growth or Select. Accordingly, anytime a security is being bought or sold
for the Growth or Select funds, it may also be bought or sold for some or all of
such institutional  accounts.  The manager anticipates acquiring additional such
accounts in the future.

American Century Services Corporation  provides physical  facilities,  including
computer hardware and software and personnel, for the day-to-day  administration
of the funds and of the manager.  The manager  pays  American  Century  Services
Corporation for such services.  The payments by the manager to American  Century
Services  Corporation  for the years ending October 31, 1996, 1995 and 1994 have
been, respectively, $118,664,664, $100,504,910 and $139,895,701.

As stated in each  prospectus,  all of the stock of  American  Century  Services
Corporation  and  American  Century  Investment  Management,  Inc.  is  owned by
American Century Companies, Inc.

Touche  will  provide  services  including  (1)  audit of the  annual  financial
statements,  (2) assistance and  consultation in connection with SEC filings and

of shares are held  separately by the custodian and the shares of each series or
class represent a beneficial interest in the principal,  earnings and profit (or
losses) of  investments  and other  assets held for each  series or class.  Your
rights  as a  shareholder  are the same for all  series  or class of  securities
unless otherwise  stated.  Within their  respective  series or class, all shares
have equal  redemption  rights.  Each share,  when  issued,  is  fully-paid  and
non-assessable.  Each share, irrespective of series or class, is entitled to one
vote for  each  dollar  of net  asset  value  represented  by such  share on all
questions.

In the  event of  complete  liquidation  or  dissolution  of  American  Century,
shareholders of each series or class of shares shall be entitled to receive, pro
rata, all of the assets less the liabilities of that series or class.

MULTIPLE CLASS STRUCTURE

The funds' Board of Directors 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 four classes of funds: an Investor Class, an Institutional
Class,  a  Service  Class and an  Advisor  Class.  Not all funds  offer all four
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, Service 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  management fee. In addition to the management fee,
however,  Service  Class  shares are  subject  to a  Shareholder  Services  Plan
(described  below),  and the  Advisor  Class  shares  are  subject  to a  Master
Distribution and Shareholder  Services Plan (also described  below).  Both plans
have been adopted by the funds' board of directors  and initial  shareholder  in
accordance with Rule 12b-1 adopted by the SEC under the 1940 Act.

RULE 12-B1

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 Directors and approved by its shareholders.  Pursuant to such
rule, the Board of Directors and initial shareholder of the funds' Service Class
and Advisor Class have approved and entered into a  Shareholder  Services  Plan,
with respect to the Service Class,  and a Master  Distribution  and  Shareholder
Services Plan,  with respect to the Advisor Class  (collectively,  the "Plans").
Both Plans are described below.

In adopting the Plans, the Board of Directors (including a majority of directors
who are not  "interested  persons"  of the funds (as  defined  in the 1940 Act),
hereafter referred to as the "independent  directors") determined that there was
a  reasonable  likelihood  that  the  Plans  would  benefit  the  funds  and the
shareholders of the affected classes.  Pursuant to Rule 12b-1,  information with
respect to revenues  and  expenses  under the Plans is presented to the Board of
Directors  quarterly for its  consideration in connection with its deliberations
as to the continuance of the Plans. Continuance of the Plans must be approved by
the Board of  Directors  (including  a majority  of the  independent  directors)
annually.  The  Plans  may be  amended  by a  vote  of the  Board  of  Directors
(including a majority of the independent  directors),  except that the Plans 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 Plans
terminate automatically in the event of an assignment and may be terminated upon
a vote of a majority of the  independent  directors  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.

SHAREHOLDER SERVICES PLAN

As described in the  Prospectuses,  the funds'  Service Class of shares are 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.   In  such  circumstances,   certain
recordkeeping  and  administrative  services  that are  provided  by the  funds'
transfer  agent for the Investor Class  shareholders  may be performed by a plan
sponsor  (or its agents) or by a  financial  intermediary.  To enable the funds'
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 Service Class shares
and the funds'  Board of  Directors  has adopted a  Shareholder  Services  Plan.
Pursuant  to the  Shareholder  Services  Plan,  the Service  Class  shares pay a
shareholder services fee of 0.25% annually of the aggregate average daily assets
of the funds' Service Class shares.

18                                                  American Century Investments

American  Century  Investment  Services,  Inc. (the  "Distributor")  enters into
contracts  with  each  financial  intermediary  for  the  provision  of  certain
shareholder  services and utilizes the shareholder  services fees received under
the Shareholder Services Plan to pay for such services. Payments may be made for
a variety  of  shareholder  services,  including,  but are not  limited  to, (a)
receiving,  aggregating and processing purchase, exchange and redemption request
from beneficial  owners  (including  contract owners of insurance  products that
utilize  the  funds as  underlying  investment  media)  of  shares  and  placing
purchase,  exchange and redemption  orders with the  Distributor;  (b) providing
shareholders  with a service that invests the assets of their accounts in shares
pursuant to specific or  pre-authorized  instructions;  (c) processing  dividend
payments from a fund on behalf of  shareholders  and assisting  shareholders  in
changing dividend options, account designations and addresses; (d) providing and
maintaining  elective services such as check writing and wire transfer services;
(e) acting as  shareholder  of record and nominee  for  beneficial  owners;  (f)
maintaining account records for shareholders and/or other beneficial owners; (g)
issuing confirmations of transactions;  (h) providing subaccounting with respect
to shares  beneficially  owned by  customers of third  parties or providing  the
information  to a fund as necessary  for such  subaccounting;  (i) preparing and
forwarding   shareholder   communications  from  the  funds  (such  as  proxies,
shareholder reports,  annual and semi-annual  financial statements and dividend,
distribution and tax notices) to shareholders  and/or other  beneficial  owners;
(j) providing other similar administrative and sub-transfer agency services; and
(k) paying "service fees" for the provision of personal,  continuing services to
investors,   as  contemplated  by  the  Rules  of  Fair  Practice  of  the  NASD
(collectively  referred to as "Shareholder  Services").  Shareholder Services do
not include those activities and expenses that are primarily  intended to result
in the sale of additional shares of the funds.

MASTER DISTRIBUTION AND SHAREHOLDER SERVICES PLAN

As described in the  Prospectuses,  the funds'  Advisor Class of shares are also
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 funds' shares in various  investment  products or in connection with various
financial services.

As with the Service Class,  certain  recordkeeping and  administrative  services
that  are  provided  by  the  funds'  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  provide  various  distribution
services.

To  enable  the  funds'  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 funds'  Board of  Directors  has
adopted a Master  Distribution and Shareholder  Services Plan (the "Distribution
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  funds'
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 funds'
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 litera-

ture  and  advertising   materials  provided  to  the  funds'  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 funds  pursuant to the terms of this Agreement and in accordance
with Rule 12b-1 of the 1940 Act.

BROKERAGE

SELECT,  HERITAGE,  GROWTH, ULTRA, VISTA, GIFTRUST AND THE EQUITY INVESTMENTS OF
BALANCED

Under the management  agreement  between the funds and the manager,  the manager
has the  responsibility of selecting brokers to execute portfolio  transactions.
The funds' policy is to secure the most favorable prices and execution of orders
on its  portfolio  transactions.  So long as that policy is met, the manager may
take into  consideration the factors discussed under this caption when selecting
brokers.

The manager receives statistical and other information and services without cost
from brokers and dealers.  The manager  evaluates such information and services,
together  with all  other  information  that it may  have,  in  supervising  and
managing the investment  portfolios of the funds.  Because such  information and
services  may vary in  amount,  quality  and  reliability,  their  influence  in
selecting brokers varies from none to very substantial.  The manager proposes to
continue to place some of the funds' brokerage business with one or more brokers
who provide  information and services.  Such information and services will be in
addition to and not in lieu of services required to be performed by the manager.
The manager does not utilize brokers that provide such  information and services
for the purpose of reducing  the expense of providing  required  services to the
funds.

In the years ended October 31, 1996, 1995 and 1994, the brokerage commissions of
each fund were as follows:

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

In 1996,  $49,120,223 of the total brokerage commissions was paid to brokers and
dealers who provided information and services on transactions of $56,023,070,599
(92% of all transactions).

The  brokerage  commissions  paid by the funds may exceed  those  which  another
broker might have charged for  effecting the same  transactions,  because of the
value of the brokerage and research  services  provided by the broker.  Research
services   furnished  by  brokers  through  whom  the  funds  effect  securities
transactions  may be used by the manager in servicing all of its  accounts,  and
not all such  services may be used by the manager in managing the  portfolios of
the funds.

The staff of the SEC has expressed the view that the best price and execution of
over-the-counter  transactions in portfolio securities may be secured by dealing
directly  with  principal  market  makers,   thereby  avoiding  the  payment  of
compensation to another broker. In certain situations, the officers of the funds
and the manager believe that the facilities,  expert personnel and technological
systems  of a broker  often  enable  the  funds to secure as good a net price by
dealing with a broker instead of a principal market maker, even after payment of
the compensation to the broker.  The funds regularly place its  over-the-counter
transactions with principal market

networks or as circumstances warrant.

INVESTMENTS OF BALANCED

Under the management  agreement  between the funds and the manager,  the manager
has the  responsibility  of selecting  brokers and dealers to execute  portfolio
transactions.  In many  transactions,  the  selection of the broker or dealer is
determined by the  availability of the desired  security and its offering price.
In other  transactions,  the  selection of broker or dealer is a function of the
selection  of  market  and the  negotiation  of price,  as well as the  broker's
general  execution and  operational  and financial  capabilities  in the type of
transaction involved. The manager will seek to obtain prompt execution of orders
at the most favorable  prices or yields.  The manager may choose to purchase and
sell portfolio  securities to and from dealers who provide services or research,
statistical  and  other  information  to the  funds  and to  the  manager.  Such
information  or services  will be in addition to and not in lieu of the services
required to be performed  by the  manager,  and the expenses of the manager will
not  necessarily  be  reduced as a result of the  receipt  of such  supplemental
information.

PERFORMANCE ADVERTISING

Individual fund  performance  may be compared to various  indices  including the
Standard & Poor's 500 Index, the Dow Jones Industrial Average,  Donoghue's Money
Fund Average and the Bank Rate Monitor National Index of 21/2-year CD rates.

EQUITY FUNDS

The  following  table sets forth the average  annual  total return of the equity
funds and  Balanced  for the one-,  five- and 10-year  periods (or period  since
inception)  ended  October 31,  1996,  the last day of the funds'  fiscal  year.
Average annual total return is calculated by determining each fund's  cumulative
total return for the stated period and then computing the annual compound return
that would produce the  cumulative  total return if the fund's  performance  had
been constant over that period. Cumulative total return includes all elements of
return, including reinvestment of dividends and capital gains distributions.

FIXED INCOME FUNDS AND BALANCED

Cash  Reserve.  The yield of Cash Reserve is  calculated by measuring the income
generated  by an  investment  in the fund over a  seven-day  period (net of fund
expenses).  This  income is then  "annualized."  That is,  the  amount of income
generated by the investment over the seven-day period is assumed to be generated
over each similar period  throughout a full year and is shown as a percentage of
the  investment.  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 of the assumed reinvestment.

Based upon these methods of computation,  the yield and effective yield for Cash
Reserve for the seven days ended  October 31,  1996,  the last seven days of the
fund's fiscal year, was 4.74% and 4.85%, respectively.

Other Fixed  Income Funds and  Balanced.  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.

The  following  table sets forth yield  quotations  for the fixed  income  funds
(other than Cash  Reserve) and Balanced for the 30-day  period ended October 31,
1996, the last day of the fiscal year pursuant to computation methods prescribed

redeeming  shareholder  might incur  brokerage costs in converting the assets to

                          NOTES TO FINANCIAL STATEMENTS


JANUARY 31, 1997 (Unaudited)

1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

ORGANIZATION  -- American  Century  Mutual  Funds,  Inc.  (the  Corporation)  is
registered under the Investment  Company Act of 1940 as an open-end  diversified
management investment company. Twentieth Century New Opportunities (the Fund) is
one of the  seventeen  series of funds  issued by the  Corporation.  The  Fund's
investment objective is capital growth. The Fund seeks to achieve its investment
objective  by  investing  primarily  in common  stocks  that are  considered  by
management to have better-than-average prospects for appreciation. The following
significant  accounting  policies,  related to the Fund, are in accordance  with
accounting policies generally accepted in the investment company industry.

SECURITY  VALUATIONS  -- Portfolio  securities  traded  primarily on a principal
securities  exchange are valued at the last reported sales price, or the mean of
the  latest  bid and  asked  prices  where no last  sales  price  is  available.
Securities traded  over-the-counter are valued at the mean of the latest bid and
asked prices or, in the case of certain foreign securities, at the last reported
sales price,  depending on local  convention or regulation.  When valuations are
not readily  available,  securities  are valued at fair value as  determined  in
accordance with procedures adopted by the Board of Directors.

SECURITY  TRANSACTIONS  -- Security  transactions  are accounted for on the date
purchased  or  sold.  Net  realized  gains  and  losses  are  determined  on the
identified cost basis, which is also used for federal income tax purposes.

INVESTMENT  INCOME -- Dividend income,  less foreign taxes withheld (if any), is
recorded as of the ex-dividend date.  Interest income is recorded on the accrual
basis and includes amortization of discounts and premiums.

REPURCHASE  AGREEMENTS  -- The Fund may enter into  repurchase  agreements  with
institutions that the Fund's  investment  manager,  American Century  Investment
Management,  Inc. (ACIM),  has determined are creditworthy  pursuant to criteria
adopted by the Board of  Directors.  Each  repurchase  agreement  is recorded at
cost.  The  Fund  requires  that  the  securities   purchased  in  a  repurchase
transaction be transferred to the custodian in a manner sufficient to enable the
Fund to obtain those  securities in the event of a default under the  repurchase
agreement.  ACIM  monitors,  on a  daily  basis,  the  value  of the  securities
transferred  to  ensure  that the  value,  including  accrued  interest,  of the
securities  under each repurchase  agreement is equal to or greater than amounts
owed to the Fund under each repurchase agreement.

JOINT TRADING ACCOUNT -- Pursuant to an Exemptive Order issued by the Securities
and  Exchange  Commission,  the Fund,  along  with other  registered  investment
companies  having   management   agreements  with  ACIM  and  Benham  Management
Corporation, may transfer uninvested cash balances into a joint trading account.
These  balances  are  invested  in one or more  repurchase  agreements  that are
collaterized by U.S. Treasury or Agency obligations.

INCOME  TAX  STATUS -- It is the policy of the Fund to  distribute  all  taxable
income and capital gains to shareholders and to otherwise qualify as a regulated
investment  company under provisions of the Internal Revenue Code.  Accordingly,
no provision has been made for federal income taxes.

DISTRIBUTIONS  TO SHAREHOLDERS --  Distributions to shareholders are recorded on
the ex-dividend date.  Distributions from net investment income and net realized
gains are declared and paid annually.

The character of distributions  made during the year from net investment  income
or net  realized  gains may differ  from  their  ultimate  characterization  for
federal income tax purposes.  These differences are primarily due to differences
in the  recognition of income and expense items for financial  statement and tax
purposes.

SUPPLEMENTARY  INFORMATION -- Certain  officers and directors of the Corporation
are also officers and/or directors, and, as a group, controlling stockholders of
American Century  Companies,  Inc., the parent of the  Corporation's  investment
manager,  ACIM,  the  Corporation's  distributor,  American  Century  Investment
Services,  Inc., and the Corporation's transfer agent, American Century Services
Corporation.

USE OF ESTIMATES -- The  preparation of financial  statements in conformity with
generally accepted  accounting  principles requires management to make estimates
and assumptions  that affect the reported  amounts of assets and liabilities and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements,  and the reported  amounts of increases  and decreases in net assets
from operations  during the reporting  period.  Actual results could differ from
those estimates.

2. TRANSACTIONS WITH RELATED PARTIES

The Corporation has entered into a Management  Agreement with ACIM that provides
the Fund with  investment  advisory  and  management  services in exchange for a
single,  unified  fee.  The  Agreement  provides  that all expenses of the Fund,
except brokerage commissions,  taxes, interest,  expenses of those directors who
are not considered "interested persons" as defined in the Investment Company Act
of 1940 (including  counsel fees) and  extraordinary  expenses,  will be paid by
ACIM.  The fee is computed  daily and paid monthly  based on the Fund's  average
daily closing net assets during the previous  month.  The annual  management fee
for the Fund is 1.5%.

3. INVESTMENT TRANSACTIONS

The aggregate  cost of investment  securities  purchased  (excluding  short-term
investments)  for the period December 26, 1996  (inception)  through January 31,
1997, totaled $90,556,978 for common stocks. Proceeds from investment securities
sold (excluding short-term investments) totaled $2,065,528 for common stocks. As
of January 31, 1997, accumulated net unrealized  appreciation on investments was
$754,496,  consisting of unrealized  appreciation  of $2,651,084  and unrealized
depreciation of $1,896,588. The aggregate cost of investments for federal income
tax purposes was the same as the cost for financial reporting purposes.

Statement of Additional Information                                            1


INVESTMENT OBJECTIVES OF THE FUNDS

The investment  objective of each fund  comprising  American  Century  Strategic
Asset Allocations,  Inc. is described on page 2 of the Prospectus. In seeking to
achieve its objective,  a fund must conform to certain  policies,  some of which
are designated in the Prospectus or in this Statement of Additional  Information
as  "fundamental"  and  cannot be  changed  without  shareholder  approval.  The
following  paragraph is also a statement of  fundamental  policy with respect to
selection of investments.

In  general,  within the  restrictions  outlined  herein,  each series has broad
powers with respect to investing funds or holding them  uninvested.  Investments
are varied  according to what is judged  advantageous  under  changing  economic
conditions. It is our policy to retain maximum flexibility in management without
restrictive  provisions  as to  the  proportion  of  one  or  another  class  of
securities that may be held,  subject to the investment  restrictions  described
below.

ADDITIONAL INVESTMENT RESTRICTIONS

Additional  fundamental  policies  that may be  changed  only  with  shareholder
approval provide as follows:

(1) The funds shall not issue senior  securities,  except as permitted under the
Investment Company Act of 1940.

(2) The funds shall not borrow money, except that the funds may borrow money for
temporary or emergency  purposes (not for leveraging or investment) in an amount
not exceeding  331/3% of a fund's total assets  (including the amount  borrowed)
less liabilities (other than borrowings).

(3) The  funds  shall  not lend any  security  or make any  other  loan if, as a
result,  more  than  331/3%  of a  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) The funds shall not concentrate  their  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).

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

(6) The funds shall not act as an  underwriter  of securities  issued by others,
except to the extent that a fund may be  considered  an  underwriter  within the
meaning  of  the  Securities  Act  of  1933  in the  disposition  of  restricted
securities.

(7) The funds shall not 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 funds from  purchasing or selling options and
futures contracts or from investing in securities or other instruments backed by
physical commodities.

(8) The  funds  shall  not  invest  for  purposes  of  exercising  control  over
management.

In addition,  the funds have adopted the  following  non-fundamental  investment
restrictions:

(1) As an  operating  policy,  a fund shall not purchase  additional  investment
securities  at any time during  which  outstanding  borrowings  exceed 5% of the
total assets of the fund.

(2) As an operating policy, a fund may not purchase any security or enter into a
repurchase  agreement if, as a result,  more than 15% of its net assets (10% for
money market funds) 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.

(3) As an operating  policy, a fund 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  transaction in futures  contracts and
options are not deemed to constitute selling securities short.

2                                                   American Century Investments

(4) As an  operating  policy,  a fund 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.

The  Investment  Company  Act  imposes  certain  additional   restrictions  upon
acquisition  by  the  funds  of  securities   issued  by  insurance   companies,
broker-dealers,  underwriters or investment advisors, and upon transactions with
affiliated persons as therein defined.  It also defines and forbids the creation
of cross and circular ownership.

The Investment Company Act also provides that the funds may not invest more than
25% of their assets in the securities of issuers  engaged in a single  industry.
In determining industry groups for purposes of this standard, the Securities and
Exchange Commission  ordinarily uses the Standard Industry  Classification codes
developed by the United States Office of Management and Budget.  In the interest
of ensuring adequate  diversification,  the funds monitor industry concentration
using a more  restrictive  list of industry groups than that  recommended by the
SEC. The funds believe that these  classifications are reasonable and are not so
broad that the primary  economic  characteristics  of the  companies in a single
class are  materially  different.  The use of these  more  restrictive  industry
classifications may, however, cause the funds to forego investment possibilities
which may otherwise be available to them under the Investment Company Act.

Neither  the SEC  nor any  other  agency  of the  federal  or  state  government
participates  in  or  supervises  the  funds'  management  or  their  investment
practices or policies.

FORWARD CURRENCY EXCHANGE CONTRACTS

The funds conduct their foreign currency exchange  transactions either on a spot
(i.e.,  cash) basis at the spot rate prevailing in the foreign currency exchange
market, or through entering into forward foreign currency exchange  contracts to
purchase or sell foreign currencies.

Each fund expects to use forward contracts under two circumstances:

(1) When the  manager  wishes to "lock in" the U.S.  dollar  price of a security
when a fund is  purchasing  or  selling  a  security  denominated  in a  foreign
currency, the fund would be able to enter into a forward contract to do so; or

(2) When the manager believes that the currency of a particular  foreign country
may suffer a substantial  decline against the U.S.  dollar, a fund would be able
to enter  into a forward  contract  to sell  foreign  currency  for a fixed U.S.
dollar  amount  approximating  the value of some or all of the fund's  portfolio
securities  either  denominated  in,  or whose  value is tied to,  such  foreign
currency.

As to the first  circumstance,  when a fund enters into a trade for the purchase
or sale of a security denominated in a foreign currency,  it may be desirable to
establish (lock in) the U.S.  dollar cost or proceeds.  By entering into forward
contracts  in U.S.  dollars  for the  purchase  or  sale of a  foreign  currency
involved in an underlying security transaction, the fund will be able to protect
itself against a possible loss between trade and settlement dates resulting from
the adverse change in the  relationship  between the U.S. dollar and the subject
foreign currency.

Under the second circumstance,  when the manager believes that the currency of a
particular country may suffer a substantial decline relative to the U.S. dollar,
a fund could enter into a forward contract to sell for a fixed dollar amount the
amount  in  foreign  currencies  approximating  the  value of some or all of its
portfolio  securities  either  denominated  in, or whose  value is tied to, such
foreign currency.  The fund will place cash or high-grade liquid securities in a
separate  account  with its  custodian  in an  amount  sufficient  to cover  its
obligation under the contract entered into under the second circumstance. If the
value of the securities placed in the separate account declines, additional cash
or  securities  will be placed in the account on a daily basis so that the value
of the account equals the amount of the fund's  commitments with respect to such
contracts.

The  precise  matching  of  forward  contracts  in the  amounts  and  values  of
securities  involved  would not generally be possible since the future values of
such

Statement of Additional Information                                            3

foreign  currencies  will change as a  consequence  of market  movements  in the
values of those securities between the date the forward contract is entered into
and the date it matures.  Predicting  short-term  currency  market  movements is
extremely  difficult,  and the  successful  execution  of a  short-term  hedging
strategy is highly  uncertain.  The  manager  does not intend to enter into such
contracts  on a regular  basis.  Normally,  consideration  of the  prospect  for
currency parities will be incorporated into the long-term  investment  decisions
made with respect to overall  diversification  strategies.  However, the manager
believes  that it is  important to have  flexibility  to enter into such forward
contracts when it determines that a fund's best interests may be served.

Generally,  a fund will not enter into a forward contract with a term of greater
than one year. At the maturity of the forward contract, the fund may either sell
the  portfolio  security and make  delivery of the foreign  currency,  or it may
retain the security and terminate the obligation to deliver the foreign currency
by purchasing an  "offsetting"  forward  contract with the same currency  trader
obligating  the fund to purchase,  on the same maturity date, the same amount of
the foreign currency.

It is  impossible  to  forecast  with  absolute  precision  the market  value of
portfolio securities at the expiration of the forward contract.  Accordingly, it
may be necessary for a fund to purchase  additional foreign currency on the spot
market  (and bear the  expense  of such  purchase)  if the  market  value of the
security is less than the amount of foreign  currency  the fund is  obligated to
deliver and if a decision is made to sell the security and make  delivery of the
foreign currency the fund is obligated to deliver.

FUTURES CONTRACTS

As described  in the  Prospectus,  each fund may enter into  futures  contracts.
Unlike when a fund  purchases  securities,  no purchase price for the underlying
securities is paid by the fund at the time it purchases a futures contract. When
a futures  contract is entered  into,  both the buyer and seller of the contract
are  required to deposit  with a futures  commission  merchant  ("FCM")  cash or
high-grade  debt securities in an amount equal to a percentage of the contract's
value,  as set by the exchange on which the  contract is traded.  This amount is
known as "initial margin" and is held by the fund's custodian for the benefit of
the FCM in the event of any  default  by the fund in the  payment  of any future
obligations.

The value of a futures  contract is adjusted daily to reflect the fluctuation of
the value of the underlying  securities.  This is a process known as marking the
contract to market. If the value of a party's position  declines,  that party is
required to make additional "variation margin" payments to the FCM to settle the
change in value. The party that has a gain is generally  entitled to receive all
or a portion of this amount.

The funds  maintain  from time to time a  percentage  of their assets in cash or
high-grade  liquid  securities to provide for  redemptions or to hold for future
investment in securities consistent with the funds' investment  objectives.  The
funds may enter into index futures contracts as an efficient means to expose the
funds' cash position to the domestic  equity market.  The manager  believes that
the purchase of futures  contracts is an efficient means to effectively be fully
invested in equity securities.

The funds intend to comply with guidelines of eligibility for exclusion from the
definition  of the term  "commodity  pool  operator"  adopted  by the  Commodity
Futures Trading Commission ("CFTC") and the National Futures Association,  which
regulate trading in the futures markets.  To do so, the aggregate initial margin
required to establish  such positions may not exceed 5% of the fair market value
of a fund's net  assets,  after  taking  into  account  unrealized  profits  and
unrealized losses on any contracts it has entered into.

The principal risks generally associated with the use of futures include:

o  the  possible  absence  of a  liquid  secondary  market  for  any  particular
instrument  may make it difficult  or  impossible  to close out a position  when
desired (liquidity risk);

o the risk  that the  counter  party to the  contract  may fail to  perform  its
obligations  or the  risk of  bankruptcy  of the  FCM  holding  margin  deposits
(counter-party risk);

o the risk that the securities to which the futures contract relates may go down
in value (market risk); and

o adverse  price  movements in the  underlying  securities  can result in losses
substantially

4                                                   American Century Investments

greater than the value of a fund's investment in that instrument  because only a
fraction of a contract's  value is required to be  deposited  as initial  margin
(leverage risk);  provided,  however,  that the funds may not purchase leveraged
futures, so there is no leverage risk involved in the funds' use of futures.

A liquid  secondary  market is necessary to close out a contract.  The funds may
seek  to  manage  liquidity  risk  by  investing  in  exchange-traded   futures.
Exchange-traded futures pose less risk that there will not be a liquid secondary
market  than   privately   negotiated   instruments.   Through  their   clearing
corporations, the futures exchanges guarantee the performance of the contracts.

Futures  contracts  are  generally  settled  within a day from the date they are
closed out, as compared to three days for most types of equity securities.  As a
result,  futures  contracts can provide more liquidity than an investment in the
actual underlying securities.  Nevertheless, there is no assurance that a liquid
secondary  market  will  exist  for  any  particular  futures  contract  at  any
particular time.  Liquidity may also be influenced by an exchange-imposed  daily
price fluctuation  limit,  which halts trading if a contract's price moves up or
down more than the established  limit on any given day. On volatile trading days
when the price fluctuation limit is reached,  it may be impossible for a fund to
enter into new  positions  or close out  existing  positions.  If the  secondary
market for a futures contract is not liquid because of price fluctuation  limits
or otherwise,  a fund may not be able to promptly liquidate  unfavorable futures
positions  and  potentially  could be  required  to  continue  to hold a futures
position  until  liquidity in the market is  re-established.  As a result,  such
fund's access to other assets held to cover its futures  positions also could be
impaired until liquidity in the market is re-established.

The funds  manage  counter-party  risk by  investing  in  exchange-traded  index
futures.  In the event of the  bankruptcy of the FCM that holds margin on behalf
of a fund,  that fund may be  entitled to the return of margin owed to such fund
only in  proportion  to the amount  received by the FCM's other  customers.  The
manager will attempt to minimize the risk by monitoring the  creditworthiness of
the FCMs with which the funds do business.

AN EXPLANATION OF FIXED INCOME SECURITIES RATINGS

As described in the Prospectus, the funds may invest in fixed income securities.
The fixed income  securities  that comprise part of a fund's bond portfolio will
primarily be limited to investment grade obligations,  provided,  that Strategic
Allocation:  Moderate  may  invest  up  to  5%  of  its  assets,  and  Strategic
Allocation:  Aggressive  may  invest  up to 10% of its  assets,  in  high  yield
securities.  In addition, each fund may invest a portion of its equity portfolio
in convertible  securities,  which may be rated below  investment grade (but not
below B- by S&P or B3 by Moody's).

Fixed income securities  ratings provide the manager with current  assessment of
the credit rating of an issuer with respect to a specific fixed income security.
The following is a description of the rating  categories  utilized by the rating
services referenced in the Prospectus disclosure:

The following  summarizes the ratings used by Standard & Poor's  Corporation for
bonds:

AAA--This  is the  highest  rating  assigned  by S&P  to a debt  obligation  and
indicates an extremely strong capacity to pay interest and repay principal.

AA--Debt  rated AA is considered to have a very strong  capacity to pay interest
and repay principal and differs from AAA issues only to 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.

BB--Debt  rated  BB has less  near-term  vulnerability  to  default  than  other
speculative issues. However, it faces major ongoing uncertainties or exposure to

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 rating.

C--The rating C typically is 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  rating CI is  reserved  for income  bonds on which no interest is being
paid.

D--Debt  rated D is in  payment  default.  The D rating  category  is used  when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired,  unless S&P believes that such payments
will be made during such grace  period.  The D rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

To provide more detailed  indications of credit quality,  the ratings from AA to
CCC may be  modified by the  addition  of a plus or minus sign to show  relative
standing within these major rating categories.

The following summarizes the ratings used by Moody's Investors Service, Inc. for
bonds:

Aaa--Bonds  that are rated Aaa are judged to be of the best quality.  They carry
the smallest  degree of 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 comprise 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
the long-term risk appear somewhat larger than the 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 some time in the future.

Baa--Bonds that are rated Baa are considered as 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 the  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 small.

6                                                   American Century Investments

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

Ca--Bonds that are rated Ca represent obligations that are speculative in 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.

Moody's applies  numerical  modifiers 1, 2 and 3 in each generic rating category
from Aa through B. The  modifier 1 indicates  that the bond being rated ranks in
the higher end of its  generic  rating  category;  the  modifier 2  indicates  a
mid-range  ranking;  and the  modifier 3 indicates a ranking in the lower end of
that generic rating category.

In the event any of a fund's fixed income  securities  are  downgraded  from one
category to another by a  securities  ratings  agency,  the  manager  intends to
evaluate  the  reasons  for  such  downgrade  and  other  available  information
regarding the issuer and will take action it deems appropriate regarding whether
or not to continue holding such securities.

INVESTING IN EMERGING MARKET COUNTRIES

Strategic Allocation: Moderate and Strategic Allocation: Aggressive may invest a
portion of their  international  holdings in  securities  of issuers in emerging
market  countries.  Investing  in  securities  of  issuers  in  emerging  market
countries  involves  exposure to  significantly  higher risk than  investing  in
countries with developed  markets.  Emerging market  countries may have economic
structures  that are generally  less diverse and mature,  and political  systems
that can be expected to be less stable than those of developed countries.

Securities  prices  in  emerging  market  countries  can be  significantly  more
volatile than in developed  countries,  reflecting the greater  uncertainties of
investing in lesser  developed  markets and economies.  In particular,  emerging
market countries may have relatively unstable  governments,  and may present the
risk of nationalization of businesses, expropriation confiscatory taxation or in
certain instances, reversion to closed-market, centrally planned economics. Such
countries  may also have less  protection  of  property  rights  than  developed
countries.

The economies of emerging market countries may be predominantly  based on only a
few industries or may be dependent on revenues from particular commodities or on
international  aid of  developmental  assistance,  may be highly  vulnerable  to
changes in local or global  trade  conditions,  and may suffer from  extreme and
volatile debt burdens or inflation  rates.  In addition,  securities  markets in
emerging  market  countries  may trade a small number of  securities  and may be
unable to  respond  effectively  to  increases  in trading  volume,  potentially
resulting in a lack of liquidity  and in  volatility  in the price of securities
traded on those markets.  Also,  securities markets in emerging market countries
typically offer less regulatory protection for investors.

SHORT SALES

A fund may  engage in short  sales if, at the time of the short  sale,  the fund
owns or has the right to  acquire  an equal  amount of the  security  being sold
short.

In a short sale, the seller does not immediately deliver the securities sold and
is said to have a short position in those securities  until delivery occurs.  To
make delivery to the  purchaser,  the executing  broker  borrows the  securities
being  sold  short  on  behalf  of the  seller.  While  the  short  position  is
maintained,  the seller  collateralizes its obligation to deliver the securities
sold  short in an  amount  equal  to the  proceeds  of the  short  sale  plus an
additional  margin amount  established  by the Board of Governors of the Federal
Reserve.  If a fund  engages in a short sale,  the  collateral  account  will be
maintained by the fund's custodian. There will be certain additional transaction
costs  associated  with short sales,  but the fund will endeavor to offset these
costs with income from the investment of the cash proceeds of short sales.

A fund may make a short  sale,  as  described  above,  when it wants to sell the
security  it owns at a  current  attractive  price,  but  also  wishes  to defer
recognition  of gain or loss for federal income tax purposes and for purposes of
satisfying certain tests applicable to regulated  investment companies under the
Internal  Revenue  Code.  In such a case,  any future  losses in the fund's long
position in substantially identical securities may not become deductible for tax
purposes until all or some part of the short position has been closed.

PORTFOLIO TURNOVER

With  respect to each  series of shares,  the  manager  will  purchase  and sell
securities  without  regard to the  length of time the  security  has been held.
Accordingly, the rate of portfolio turnover may be greater than other investment
companies with similar investment objectives.

The funds intend to purchase a given security  whenever the manager  believes it
will contribute to the stated objective of a fund, even if the same security has
only recently been sold. In selling a given security,  the manager keeps in mind
that (1) profits  from sales of  securities  held less than three months must be
limited  in order to meet  the  requirements  of  Subchapter  M of the  Internal
Revenue  Code,   and  (2)  profits  from  sales  of  securities   are  taxed  to
shareholders.  Subject  to  those  considerations,  a fund  will  sell  a  given
security,  no matter  for how long or how short a period it has been held in the
portfolio,  and no  matter  whether  the sale is at a gain or at a loss,  if the
manager  believes  that the  security  is not  fulfilling  its  purpose,  either
because,  among other things, it did not live up to the manager's  expectations,
or because it may be replaced with another security holding greater promise,  or
because it has  reached  its  optimum  potential,  or because of a change in the
circumstances  of a  particular  company  or  industry  or in  general  economic
conditions, or because of some combination of such reasons.

When a general decline in securities prices is anticipated,  a fund may decrease
its  position in such  category  and increase its position in one or both of the
other asset categories,  and when a rise in price levels is anticipated,  a fund
may  increase  its  position in such  category  and decrease its position in the
other  categories.  However,  the  funds  will,  under  most  circumstances,  be
essentially  fully  invested  within  the  operating  ranges  set  forth  in the
Prospectus.

Since  investment  decisions are based on the  anticipated  contribution  of the
security in question to a fund's objectives,  the manager believes that the rate
of  portfolio  turnover is  irrelevant  when it believes a change is in order to
achieve those objectives,  and a fund's annual portfolio turnover rate cannot be
anticipated and may be comparatively  high. This disclosure  regarding portfolio
turnover is a statement of fundamental  policy and may be changed only by a vote
of the shareholders.

Since the manager does not take  portfolio  turnover rate into account in making
investment  decisions,  (1) the manager has no  intention of  accomplishing  any
particular  rate  of  portfolio  turnover,  whether  high  or  low,  and (2) the
portfolio   turnover   rates  in  the  past  should  not  be   considered  as  a
representation of the rates which will be attained in the future.

The Board of Directors has established four standing  committees:  the Executive
Committee,  the Audit  Committee,  the  Compliance  Committee and the Nominating
Committee.

Messrs.  Stowers  Jr.,  Stowers  III  and  Lundgaard  constitute  the  Executive
Committee of the Board of Directors. The committee performs the functions of the
Board of Directors between meetings of the Board,  subject to the limitations on
its power set out in the  Maryland  General  Corporation  Law,  and  except  for
matters  required  by the  Investment  Company Act to be acted upon by the whole
Board.

Messrs. Lundgaard (chairman), Doering and Hock and Ms. Strandjord constitute the
Audit Committee.  The functions of the Audit Committee include  recommending the
engagement of the funds'  independent  auditors,  reviewing the arrangements for
and  scope of the  annual  audit,  reviewing  comments  made by the  independent
auditors with respect to internal controls and the  considerations  given or the
corrective  action taken by management and reviewing  nonaudit services provided
by the independent auditors.

Messrs. Brown (chairman),  Pratt and Silver constitute the Compliance Committee.
The functions of the Compliance  Committee  include reviewing the results of the
funds' compliance testing program,  reviewing quarterly reports from the manager
to  the  Board  regarding   various   compliance   matters  and  monitoring  the
implementation of the funds' Code of Ethics, including any violations thereof.

The  Nominating  Committee  has as its  principal  role  the  consideration  and
recommendation  of  individuals  for  nomination  as  directors.  The  names  of
potential  director  candidates  are drawn from a number of  sources,  including
recommendations  from members of the Board,  management and  shareholders.  This
committee  also reviews and makes  recommendations  to the Board with respect to
the composition of Board committees and other Board-related  matters,  including
its   organization,   size,   composition,   responsibilities,   functions   and
compensation.  The  members  of  the  nominating  committee  are  Messrs.  Pratt
(chairman), Lundgaard and Stowers III.

The Directors of the corporation also serve as Directors for other funds advised
by the manager.  Each Director who is not an  "interested  person" as defined in
the Investment  Company Act receives for service as a member of the Board of all
six of such companies an annual director's fee of $44,000, and an additional fee
of $1,000 per regular Board meeting  attended and $500 per special Board meeting
and  committee  meeting  attended.  In  addition,  those  directors  who are not
"interested  persons"  and  serve as  chairman  of a  committee  of the Board of
Directors  receive  an  additional  $2,000  for such  services.  These  fees and
expenses  are  divided  among the six  investment  companies  based  upon  their
relative  net  assets.  Under the  terms of the  management  agreement  with the
manager, the funds are responsible for paying such fees and expenses.  Set forth
below is the aggregate  compensation paid for the periods indicated by the funds
and by the American  Century  family of funds as a whole to each Director who is
not an "interested person" as defined in the Investment Company Act.

The Advisor  Class of the funds  commenced  operations  on October 2, 1996.  The
management  fees shown  above  include  $4,575 paid on Advisor  Class  shares of
Strategic  Allocation:  Conservative,  $9,815  paid on Advisor  Class  shares of
Strategic  Allocation:  Moderate  and  $8,332  paid on Advisor  Class  shares of
Strategic Allocation: Aggressive for the 59 day period ended November 30, 1996.

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 (i) the funds'
Board of  Directors,  or by the vote of a  majority  of  outstanding  votes  (as
defined in the Investment Company Act) and (ii) by the vote of a majority of the
Directors  of the funds  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 funds'  Board of  Directors,  or by a vote of a
majority of the funds' 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
funds 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,
directors 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 funds and also for other clients
advised by the manager. Investment decisions for the funds 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 a fund.

The manager may  aggregate  purchase and sale orders of the funds with  purchase
and sale  orders  of its  

10                                                  American Century Investments

other clients when the manager believes that such aggregation  provides the best
execution  for the funds.  The funds' Board of Directors has approved the policy
of the manager with respect to the aggregation of portfolio transactions.  Where
portfolio  transactions  have  been  aggregated,  the funds  participate  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 funds  unless it believes  such  aggregation  is
consistent  with its duty to seek best  execution on behalf of the funds 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 funds,  on February  28, 1997,  the manager was also
acting  as an  investment  adviser  to 12  institutional  accounts  and to  five
registered investment  companies,  American Century Mutual Funds, Inc., American
Century World Mutual Funds,  Inc.,  American  Century  Premium  Reserves,  Inc.,
American  Century  Variable  Portfolios,   Inc.  and  American  Century  Capital
Portfolios, Inc.

American Century Services Corporation  provides physical  facilities,  including
computer hardware and software and personnel, for the day-to-day  administration
of the funds and of the manager.  The manager  pays  American  Century  Services
Corporation for such services.

As  stated in the  Prospectus,  all of the stock of  American  Century  Services
Corporation  and  American  Century  Investment  Management,  Inc.  is  owned by
American Century Companies, Inc.

CUSTODIANS

The  Chase  Manhattan  Bank,  770  Broadway,  10th  floor,  New  York,  New York
10003-9598 and Commerce Bank,  N.A., 1000 Walnut,  Kansas City,  Missouri 64105,
each serves as custodian of assets of the funds.  The custodians take no part in
determining the investment policies of the funds or in deciding which securities
are purchased or sold by the funds.  The funds,  however,  may invest in certain
obligations of the custodians and may purchase or sell certain  securities  from
or to the custodians.

INDEPENDENT AUDITORS

At a  meeting  held  on  December  12,  1996,  the  Board  of  Directors  of the
corporation  appointed  Deloitte & Touche LLP, 1010 Grand  Avenue,  Kansas City,
Missouri  64106,  as the  independent  auditors  of the  funds  to  examine  the
financial  statements of the funds for the fiscal year ending November 30, 1997.
The  appointment of Deloitte & Touche was  recommended by the Audit Committee of
the Board of Directors.  As the  independent  auditors of the funds,  Deloitte &
Touche  will  provide  services  including  (1)  audit of the  annual  financial
statements,  (2) assistance and  consultation in connection with SEC filings and
(3)  review of the  annual  federal  income  tax  return  filed for each fund by
American Century.

Ernst & Young  LLP,  One Kansas  City  Place,  1200 Main  Street,  Kansas  City,
Missouri  64105,  served as  independent  auditors  for the funds for the period
ended November 30, 1996.

CAPITAL STOCK

The funds'  capital  stock is  described  in the  Prospectus  under the  heading
"Further Information About American Century."

The corporation currently has three series of shares outstanding. Each series of
shares is further divided into three classes.  The funds may in the future issue
one or  more  additional  series  or  class  of  shares  without  a vote  of the
shareholders.  The assets  belonging  to each series or class of shares are held
separately by the  custodian and the shares of each series or class  represent a
beneficial  interest  in the  principal,  earnings  and  profits  (or losses) of
investment  and other  assets  held for that  series or class.  Your rights as a
shareholder  are the  same  for all  series  or  classes  of  securities  unless
otherwise stated.  Within their respective series or class, all shares will have
equal  redemption   rights.   Each  share,   when  issued,  is  fully  paid  and
non-assessable.  Each share, irrespective of series or class, is entitled to one
vote for  each  dollar  of net  asset  value  represented  by such  share on all
questions.

In the event of complete  liquidation or dissolution of the funds,  shareholders
of each series or class of shares will be entitled to receive,  pro rata, all of
the assets less the liabilities of that series or class.

As of  February  28,  1997,  in  excess of 5% of the  outstanding  shares of the

MULTIPLE CLASS STRUCTURE

The funds' Board of Directors has adopted a multiple class plan (the "Multiclass
Plan") pursuant to Rule 18f-3 adopted by the Securities and Exchange  Commission
("SEC").  Pursuant  to such  plan,  the funds may issue up to three  classes  of
shares: an Investor Class, a Service Class and an Advisor Class.

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 Service 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 management fee. In addition to the management fee, however,  Service Class
shares are subject to a Shareholder  Services Plan  (described  below),  and the
Advisor  Class  shares are  subject  to a Master  Distribution  and  Shareholder
Services Plan (also described below). Both plans have been adopted by the funds'
Board of Directors 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 Directors and approved by its shareholders.  Pursuant to such
rule, the Board of Directors and initial shareholder of the funds' Service Class
and Advisor Class have approved and entered into a  Shareholder  Services  Plan,
with respect to the Service Class,  and a Master  Distribution  and  Shareholder
Services Plan,  with respect to the Advisor Class  (collectively,  the "Plans").
Both Plans are described below.

In adopting the Plans, the Board of Directors (including a majority of directors
who are not  "interested  persons"  of the funds (as  defined in the  Investment
Company Act), hereafter referred to as the "independent  directors")  determined
that there was a reasonable  likelihood  that the Plans would  benefit the funds
and  the  shareholders  of  the  affected  classes.   Pursuant  to  Rule  12b-1,
information  with respect to revenues and expenses  under the Plans is presented
to the Board of Directors quarterly for its consideration in connection with its
deliberations as to the continuance of the Plans.  Continuance of the Plans must
be approved by the Board of Directors  (including a majority of the  independent
directors)  annually.  The  Plans  may be  amended  by a vote  of the  Board  of
Directors (including a majority of the independent  directors),  except that the
Plans 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 Plans terminate  automatically in the event of an assignment and may
be terminated upon a vote of a majority of the independent  directors 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.

SHAREHOLDER SERVICES PLAN

As  described in the  Prospectus,  the funds'  Service  Class of shares are 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.   In  such  circumstances,   certain
recordkeeping  and  administrative  services  that are  provided  by the  funds'
transfer  agent for the Investor Class  shareholders  may be performed by a plan
sponsor  (or its agents) or by a  financial  intermediary.  To enable the funds'
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 Service Class shares
and the funds'  Board of  Directors  has adopted a  Shareholder  Services  Plan.
Pursuant  to the  Shareholder  Services  Plan,  the Service  Class  shares pay a
shareholder  services fee of 0.25%  annually of the aggregate  average daily net
assets of the funds' Service Class shares.

American  Century  Investment  Services,  Inc. (the  "Distributor")  enters into
contracts  with  each  financial  intermediary  for  the  provision  of  certain
shareholder  services  and  utilizes  the  shareholder  services  fees under the
Shareholder  Services Plan to pay for such services.  Payments may be made for a
variety  of  shareholder  services,  including,  but are  not  limited  to,  (1)
receiving,  aggregating and processing purchase, exchange and redemption request
from beneficial  owners  (including  contract owners of insurance  products that
utilize  the  funds as  underlying  investment  medium)  of shares  and  placing
purchase,  exchange and redemption  orders with the  Distributor;  (2) providing
shareholders  with a service that invests the assets of their accounts in shares
pursuant to specific or  pre-authorized  instructions;  (3) processing  dividend
payments from a fund on behalf of  shareholders  and assisting  shareholders  in
changing dividend options, account designations and addresses; (4) providing and
maintaining  elective services such as check writing and wire transfer services;
(5) acting as  shareholder  of record and nominee  for  beneficial  owners;  (6)
maintaining account records for shareholders and/or other beneficial owners; (7)
issuing confirmations of transactions;  (8) providing subaccounting with respect
to shares  beneficially  owned by  customers of third  parties or providing  the
information  to a fund as necessary  for such  subaccounting;  (9) preparing and
forwarding   shareholder   communications  from  the  funds  (such  as  proxies,
shareholder reports,  annual and semi-annual  financial statements and dividend,
distribution and tax notices) to shareholders  and/or other  beneficial  owners;
(10) providing other similar  administrative  and sub-transfer  agency services;
and (11)  paying  "service  fees"  for the  provision  of  personal,  continuing
services to investors, as contemplated by the Rules of Fair Practice of the NASD
(collectively  referred to as "Shareholder  Services").  Shareholder Services do
not include those activities and expenses that are primarily  intended to result
in the sale of additional shares of the funds.

MASTER DISTRIBUTION AND SHAREHOLDER SERVICES PLAN

As described in the Prospectus, the funds' Advisor Class of shares are also 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 funds' shares in various  investment  products or in connection with various
financial services.

As with the Service Class,  certain  recordkeeping and  administrative  services
that  are  provided  by  the  funds'  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  provide  various  distribution
services.

To  enable  the  funds'  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 funds'  Board of  Directors  has
adopted a Master  Distribution and Shareholder  Services Plan (the "Distribution
Plan").  Pursuant  to such Plan,  the  Advisor  Class  shares pay a fee of 0.50%
annually of the aggregate  average daily net assets of the funds'  Advisor Class
shares, 0.25% of which is 

Statement of Additional Information                                           13

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,  (1) 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;  (2)  compensation to registered  representatives  or other
employees of  Distributor  who engage in or support  distribution  of the funds'
Advisor Class shares; (3) compensation to, and expenses  (including overhead and
telephone  expenses)  of,   Distributor;   (4)  the  printing  of  prospectuses,
statements  of  additional  information  and  reports  for other  than  existing
shareholders; (5) the preparation, printing and distribution of sales literature
and advertising  materials  provided to the funds'  shareholders and prospective
shareholders;  (6)  receiving  and  answering  correspondence  from  prospective
shareholders,  including  distributing  prospectuses,  statements  of additional
information,  and shareholder reports; (7) the providing of facilities to answer
questions  from  prospective  investors  about fund shares;  (8) complying  with
federal and state  securities  laws  pertaining to the sale of fund shares;  (9)
assisting  investors in completing  application forms and selecting dividend and
other  account  options;  (10) the providing of other  reasonable  assistance in
connection  with  the  distribution  of fund  shares;  (11) the  organizing  and
conducting  of  sales  seminars  and  payments  in  the  form  of  transactional
compensation or promotional incentives;  (12) profit on the foregoing;  (13) 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 (14)
such other distribution and services activities as the manager determines may be
paid for by the funds  pursuant to the terms of this Agreement and in accordance
with Rule 12b-1 of the Investment Company Act.

TAXES

Each fund has elected to be taxed under  Subchapter  M of the  Internal  Revenue
Code as a  regulated  investment  company.  If they  qualify,  they  will not be
subject to U.S. federal income tax on net ordinary income and net capital gains,
which are distributed to its shareholders  within certain time periods specified
in the Code.  Amounts  not  distributed  on a timely  basis  would be subject to
federal and state corporate income tax and to a nondeductible 4% excise tax.

Distributions by the funds from net investment income and net short-term capital
gains are taxable to shareholders  as ordinary  income.  The dividends  received
deduction available to corporate shareholders for dividends received from a fund
will apply to  ordinary  income  distributions  only to the extent that they are
attributable to the fund's dividend income from U.S. corporations.  In addition,
the dividends  received  deduction will be limited if the shares with respect to
which the dividends are received are treated as  debt-financed  or are deemed to
have been held less than 46 days by a fund.

Distributions  from net long-term  capital gains are taxable to a shareholder as
long-term  capital  gains  regardless  of the length of time the shares on which
such  distributions  are  paid  have  been  held  by the  shareholder.  However,
shareholders  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 the shareholder
with respect to such shares.

Redemption of shares of a fund will be a taxable  transaction for federal income
tax purposes and shareholders will generally recognize 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.

In addition to the federal income tax  consequences  described above relating to
an investment in shares of the funds, there may be other federal, state or local
tax  considerations  that  depend  upon  the  circumstances  of each  particular
investor.  Prospective  shareholders  are  therefore  urged to consult their tax


14                                                  American Century Investments

advisors with respect to the effect of this investment on their own situations.

BROKERAGE

Under the management  agreement  between the funds and the manager,  the manager
has the  responsibility of selecting brokers to execute portfolio  transactions.
The funds' policy is to secure the most favorable prices and execution of orders
on its  portfolio  transactions.  So long as that policy is met, the manager may
take into  consideration the factors discussed under this caption when selecting
brokers.

The manager receives statistical and other information and services without cost
from brokers and dealers.  The manager  evaluates such information and services,
together  with all  other  information  that it may  have,  in  supervising  and
managing the investments of the funds. Because such information and services may
vary in amount,  quality and reliability,  their influence in selecting  brokers
varies from none to very substantial.  The manager proposes to continue to place
some of the funds'  brokerage  business  with one or more  brokers  who  provide
information and services.  Such  information and services will be in addition to
and not in lieu of the services  required to be  performed  by the manager.  The
manager does not utilize  brokers who provide such  information and services for
the purpose of reducing the expense of providing required services to the funds.

In the period from  February  15, 1996  (inception)  through  November 30, 1996,
brokerage commissions paid by each fund were as follows:

                                               Period ended
Fund                                         November 30, 1996
- -------------------------------------------------------------------------
Strategic Allocation: Conservative               $22,060
Strategic Allocation: Moderate                     81,203
Strategic Allocation: Aggressive                   74,216
- -------------------------------------------------------------------------

The brokerage commissions paid by the funds may exceed those that another broker
might have charged for effecting the same  transactions  because of the value of
the brokerage and/or research services provided by the broker. Research services
furnished by brokers through whom the funds effect  securities  transactions may
be used by the  manager  in  servicing  all of its  accounts,  and not all  such
services may be used by the manager in managing the portfolios of the funds.

The staff of the SEC has expressed the view that the best price and execution of
over-the-counter  transactions in portfolio securities may be secured by dealing
directly  with  principal  market  makers,   thereby  avoiding  the  payment  of
compensation to another broker. In certain situations, the officers of the funds
and the manager believe that the facilities,  expert personnel and technological
systems  of a broker  enable  the funds to secure as good a net price by dealing
with a broker  instead of a principal  market  maker,  even after payment of the
compensation  to the broker.  The funds  normally  place their  over-the-counter
transactions with principal market makers but also may deal on a brokerage basis
when utilizing electronic trading networks or as circumstances warrant.

PERFORMANCE ADVERTISING

FUND PERFORMANCE

Individual fund  performance  may be compared to various  indices  including the
Standard & Poor's (S&P) 500 Index, the Dow Jones Industrial Average,  the Lehman
Aggregate Bond Index and the Three-Month Treasury Bill Index.

Average annual total return is calculated by determining each fund's  cumulative
total return for the stated period and then computing the annual compound return
that would produce the  cumulative  total return if the fund's  performance  had
been constant over that period.  The following  table sets forth the  cumulative
total return since  inception for the Investor Class of the funds for the period
from  February 15, 1996  through  November  30,  1996.  Cumulative  total return
includes all elements of return, including reinvestment of dividends and capital
gains  distribution.  Annualization  of a fund's return assumes that the partial
year performance will be constant  throughout the period.  Actual return through
the period may be greater or less than the annualized data.

The funds also may elect to advertise cumulative total return and average annual
total return,  computed

as described  above,  over periods of time other than one, five and 10 years and
cumulative total return over various time periods.

ADDITIONAL PERFORMANCE COMPARISONS

Investors may judge the performance of the funds by comparing their  performance
to the  performance  of  other  mutual  funds or  mutual  fund  portfolios  with
comparable  investment  objectives and policies  through  various mutual fund or
market indices such as those prepared by Dow Jones & Co., Inc. Standard & Poor's
Corporation,  Shearson Lehman  Brothers,  Inc., J. P. Morgan & Company,  Salomon
Brothers, Inc., the Morgan Stanley Capital International EAFE (Europe, Australia
and Far East)  Index,  Donoghue's  Money  Fund  Average,  the Bank Rate  Monitor
National  Index of  21/2-year  CD rates,  IFC  Global  Composite  Index,  and to
composite  indices  consisting  of two or more of the  above to more  accurately
reflect fund holdings, and to data prepared by Lipper Analytical Services,  Inc.
or Morningstar,  Inc., and to the Consumer Price Index.  Comparisons may also be
made to indices or data published in Money Magazine,  Forbes, Barron's, The Wall
Street Journal,  The New York Times,  Business Week,  Pensions and  Investments,
U.S.A.  Today,  and other  similar  publications  or  services.  In  addition to
performance  information,  general information about the funds that appears in a
publication such as those mentioned above or in the Prospectus under the heading
"Performance  Advertising" may be included in  advertisements  and in reports to
shareholders.

PERMISSIBLE ADVERTISING INFORMATION

From  time to  time,  the  funds  may,  in  addition  to any  other  permissible
information,  include the  following  types of  information  in  advertisements,
supplemental sales literature and reports to shareholders:

(1)  discussions  of  general  economic  or  financial  principles  (such as the
     effects of compounding and the benefits of dollar-cost averaging);

(2)  discussions of general economic trends;

(3)  presentations of statistical data to supplement such discussions;

(4)  descriptions of past or anticipated  portfolio  holdings for one or more of
     the funds;

(5)  descriptions of investment strategies for one or more of the funds;

(6)  descriptions  or  comparisons of various  savings and  investment  products
     (including,  but not limited to, qualified  retirement plans and individual
     stocks and bonds). which may or may not include the funds;

(7)  comparisons  of  investment  products  (including  the funds) with relevant
     market or industry indices or other appropriate benchmarks;

(8)  discussions   of  fund   rankings   or   ratings  by   recognized   ratings
     organizations; and

(9)  testimonials describing the experience of persons that have invested in one
     or more of the funds.

The  funds  may also  include  calculations,  such as  hypothetical  compounding
examples, which describe hypothetical investment results in such communications.
Such performance examples will be based on an express set of assumptions and are
not indicative of the performance of any of the funds.

REDEMPTIONS IN KIND

The funds' policy with regard to large redemptions is described in detail in the
Prospectus under the heading "Special Requirements for Large Redemptions."

The funds have elected to be governed by Rule 18f-1 under the Investment Company
Act of 1940,  pursuant to which the funds are  obligated to redeem shares solely
in cash up to the  lesser of  $250,000  or 1% of the net  asset  value of a fund
during any 90-day  period for any one  shareholder.  If shares are  redeemed  in
kind, the redeeming  shareholder  might incur  brokerage costs in converting the
assets to cash. The securities delivered will be selected at the sole discretion
of the  manager  and  will  not  necessarily  be  representative  of the  entire
portfolio and will be securities  that the manager  regards as least  desirable.
The method of valuing  securities  used to make  redemptions in kind will be the
same as the method of valuing portfolio  securities  described in the Prospectus
under the heading "How Share Price is  Determined,"  and such  valuation will be
made as of the same time the redemption price is determined.

HOLIDAYS

The funds do not  determine  the net asset  value of its shares on days when the
New York Stock Exchange

16                                                 American Century Investments

is closed.  Currently,  the Exchange is closed on  Saturdays  and Sundays and on
holidays,  namely New Year's Day, Martin Luther King Jr. Day,  Presidents'  Day,
Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,  Thanksgiving  and
Christmas.

                         Prospectus dated April 1, 1997

The  disclosure  set forth below  replaces  footnote  (4) found on page 4 of the
Investor Class Prospectus:

"(4) International Growth pays an annual management fee of 1.50% of the first $1
     billion of average net assets,  1.20% of the next $1 billion of average net
     assets, and 1.10% of average net assets over $2 billion,  and International
     Discovery pays an annual  management fee of 1.75% of the first $500 million
     of average  net  assets,  1.40% of the next $500  million  of  average  net
     assets, and 1.20% of average net assets over $1 billion."

The disclosure set forth below  replaces the first  paragraph  under the heading
"Short  Sales"  found  on  page  13 of  the  Investor  and  Institutional  Class
Prospectuses and page 14 of the Advisor Class Prospectus:

     "A fund may engage in short  sales if, at the time of the short  sale,  the
fund owns or has the right to acquire  securities  equivalent in kind and amount
to the securities being sold short.  Such  transactions  allow the fund to hedge
against price fluctuations by locking in a sale price for securities it does not

INVESTMENT OBJECTIVES OF THE FUNDS

     The investment  objective of each fund  comprising  American  Century World
Mutual  Funds,  Inc. is  described  on page 2 of the  Prospectus.  In seeking to
achieve its objective,  a fund must conform to certain  policies,  some of which
are designated in the Prospectus or in this Statement of Additional  Information
as  "fundamental"  and  cannot be  changed  without  shareholder  approval.  The
following  paragraph is also a statement of  fundamental  policy with respect to
selection of investments.

     In general,  within the restrictions outlined herein, each series has broad
powers with respect to investing funds or holding them  uninvested.  Investments
are varied  according to what is judged  advantageous  under  changing  economic
conditions. It is our policy to retain maximum flexibility in management without
restrictive  provisions  as to  the  proportion  of  one  or  another  class  of
securities that may be held,  subject to the investment  restrictions  described
below.  It is the manager's  intention that each fund will generally  consist of
common stocks.  However,  the manager may invest the assets of a fund in varying
amounts  in  other  instruments  and  in  senior  securities,   such  as  bonds,
debentures,  preferred  stocks  and  convertible  issues,  when such a course is
deemed appropriate in order to attempt to attain its financial objective.

ADDITIONAL INVESTMENT RESTRICTIONS

     Additional  fundamental  policies that may be changed only with shareholder
approval provide as follows:

     (1) The funds shall not issue senior securities,  except as permitted under
the Investment Company Act of 1940.

     (2) The funds  shall not  borrow  money,  except  that the funds may borrow
money for temporary or emergency  purposes (not for leveraging or investment) in
an amount not exceeding  331/3% of a fund's total assets  (including  the amount
borrowed) less liabilities (other than borrowings).

     (3) The funds  shall not lend any  security or make any other loan if, as a
result,  more  than  331/3%  of a  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) The funds shall not  concentrate  their  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).

     (5) The funds shall not purchase or sell real estate  unless  acquired as a
result of ownership of  securities or other  instruments.  This policy shall not
prevent a 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.

     (6) The  funds  shall not act as an  underwriter  of  securities  issued by
others, except to the extent that a fund may be considered an underwriter within
the  meaning of the  Securities  Act of 1933 in the  disposition  of  restricted
securities.

     (7) The funds  shall  not  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 funds from  purchasing  or selling
options  and  futures  contracts  or  from  investing  in  securities  or  other
instruments backed by physical commodities.

     (8) The funds shall not invest for  purposes  of  exercising  control  over
management.

     In  addition,   the  funds  have  adopted  the  following   non-fundamental
investment restrictions:

     (1) As an operating policy, a fund shall not purchase additional investment
securities  at any time during  which  outstanding  borrowings  exceed 5% of the
total assets of the fund.

     (2) As an operating  policy,  a fund may 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.


2                                                 American Century Investments



     (3) As an operating policy, a fund 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  transaction in futures  contracts
and options are not deemed to constitute selling securities short.

     (4) As an operating policy, a fund 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.

     The Investment  Company Act imposes certain  additional  restrictions  upon
acquisition  by  the  funds  of  securities   issued  by  insurance   companies,
broker-dealers,  underwriters or investment advisors, and upon transactions with
affiliated persons as therein defined.  It also defines and forbids the creation
of cross and circular ownership.

     The Investment Company Act also provides that the funds may not invest more
than 25% of their  assets  in the  securities  of  issuers  engaged  in a single
industry.  In determining  industry  groups for purposes of this  standard,  the
Securities  and  Exchange  Commission  ordinarily  uses  the  Standard  Industry
Classification  codes  developed by the United States  Office of Management  and
Budget. In the interest of ensuring adequate diversification,  the funds monitor
industry  concentration  using a more  restrictive  list of industry groups than
that  recommended by the SEC. The funds believe that these  classifications  are
reasonable and are not so broad that the primary economic characteristics of the
companies  in a single  class are  materially  different.  The use of these more
restrictive  industry  classifications  may, however,  cause the funds to forego
investment  possibilities  which may  otherwise  be  available to them under the
Investment Company Act.

     Neither  the SEC nor any other  agency of the  federal or state  government
participates  in  or  supervises  the  funds'  management  or  their  investment
practices or policies.

FORWARD CURRENCY EXCHANGE CONTRACTS

     The funds conduct their foreign currency exchange  transactions either on a
spot (i.e.,  cash)  basis at the spot rate  prevailing  in the foreign  currency
exchange  market,  or through  entering into forward foreign  currency  exchange
contracts to purchase or sell foreign currencies.

     Each fund expects to use forward contracts under two circumstances:

     (1) When  the  manager  wishes  to "lock  in" the  U.S.  dollar  price of a
security  when the fund is  purchasing  or selling a security  denominated  in a
foreign currency,  the fund would be able to enter into a forward contract to do
so; or

     (2) When the manager  believes  that the currency of a  particular  foreign
country may suffer a substantial decline against the U.S. dollar, the fund would
be able to enter into a forward  contract to sell  foreign  currency for a fixed
U.S.  dollar  amount  approximating  the  value  of  some  or all of the  fund's
portfolio  securities  either  denominated  in, or whose  value is tied to, such
foreign currency.

     As to the  first  circumstance,  when a fund  enters  into a trade  for the
purchase  or sale of a security  denominated  in a foreign  currency,  it may be
desirable to establish (lock in) the U.S.  dollar cost or proceeds.  By entering
into  forward  contracts  in U.S.  dollars for the purchase or sale of a foreign
currency involved in an underlying security  transaction,  the fund will be able
to protect  itself  against a possible loss between trade and  settlement  dates
resulting from the adverse change in the  relationship  between the U.S.  dollar
and the subject foreign currency.

     Under the second circumstance,  when the manager believes that the currency
of a particular  country may suffer a substantial  decline  relative to the U.S.
dollar,  a fund could enter into a forward  contract to sell for a fixed  dollar
amount the amount in foreign  currencies  approximating the value of some or all
of its portfolio  securities  either  denominated in, or whose value is tied to,
such foreign currency.  The fund will place cash or high-grade liquid securities
in a separate  account with its  custodian in an amount  sufficient to cover its
obligation  under the  contract.  If the value of the  securities  placed in the
separate account declines,

Statement of Additional Information                                            3




additional  cash or securities will be placed in the account on a daily basis so
that the value of the account equals the amount of the fund's  commitments  with
respect to such contracts.

     The  precise  matching  of forward  contracts  in the amounts and values of
securities  involved  would not generally be possible since the future values of
such foreign  currencies will change as a consequence of market movements in the
values of those securities between the date the forward contract is entered into
and the date it matures.  Predicting  short-term  currency  market  movements is
extremely difficult, and the successful execution of short-term hedging strategy
is highly  uncertain.  Normally,  consideration  of the  prospect  for  currency
parities will be incorporated into the long-term  investment decisions made with
respect to overall  diversification  strategies.  However,  the manager believes
that it is important to have  flexibility  to enter into such forward  contracts
when it determines that a fund's best interests may be served.

     Generally,  a fund will not enter  into a forward  contract  with a term of
greater  than one year.  At the maturity of the forward  contract,  the fund may
either sell the portfolio security and make delivery of the foreign currency, or
it may retain the security and terminate  the  obligation to deliver the foreign
currency by purchasing an "offsetting"  forward  contract with the same currency
trader  obligating  the fund to purchase,  on the same maturity  date,  the same
amount of the foreign currency.

     It is impossible  to forecast  with absolute  precision the market value of
portfolio securities at the expiration of the forward contract.  Accordingly, it
may be necessary for a fund to purchase  additional foreign currency on the spot
market  (and bear the  expense  of such  purchase)  if the  market  value of the
security is less than the amount of foreign  currency  the fund is  obligated to
deliver and if a decision is made to sell the security and make  delivery of the
foreign currency the fund is obligated to deliver.

AN EXPLANATION OF FIXED INCOME SECURITIES RATINGS

     As  described  in the  Prospectus,  the  funds may  invest in fixed  income
securities.   International   Growth   may  invest   only  in   investment-grade
obligations,  while  International  Discovery and the Emerging  Markets Fund may
invest in bonds, corporate debt securities and governmental  obligations without
regard to credit quality  restrictions if such obligations are determined by the
manager to be sound investments.

     Fixed  income  securities  ratings  provide  the  manager  with  a  current
assessment  of the credit  rating of an issuer with respect to a specific  fixed
income  security.  The  following  is a  description  of the  rating  categories
utilized by the rating services referenced in the Prospectus disclosure.

     The following  summarizes the ratings used by Standard & Poor's Corporation
for bonds:

     AAA -- This is the highest rating  assigned by S&P to a debt obligation and
indicates an extremely strong capacity to pay interest and repay principal.

     AA -- Debt rated AA is  considered  to have a very  strong  capacity to pay
interest and repay principal and differs from AAA issues only to 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.

     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
also is 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

4                                                   American Century Investments




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 rating.

     C -- The rating C typically is applied to debt subordinated to senior debt,
which 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 rating CI is  reserved  for income  bonds on which no interest is
being paid.

     D -- Debt rated D is in payment default. The D rating category is used when
interest payments or principal payments are not made on the date due even if the
applicable grace period has not expired,  unless S&P believes that such payments
will be made during such grace  period.  The D rating also will be used upon the
filing of a bankruptcy petition if debt service payments are jeopardized.

     To provide more detailed indications of credit quality, the ratings from AA
to CCC may be modified by the addition of a plus or minus sign to show  relative
standing within these major rating categories.

     The following  summarizes  the ratings used by Moody's  Investors  Service,
Inc. for bonds:

     Aaa -- Bonds that are rated Aaa are judged to be of the best quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
"gilt edge." Interest  payments are protected by a large or by an  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 comprise what generally are 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 the  long-term  risk  appear  somewhat  larger  than the 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 some time in the future.

     Baa -- Bonds that are rated Baa are considered as 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 over the  future.  Uncertainty  of
position characterizes bonds in this class.

     B -- Bonds that are rated B generally lack characteristics of the 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 small.

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

     Ca -- Bonds that are rated Ca represent obligations that are speculative in
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


Statement of Additional Information                                            5




as  having  extremely  poor  prospects  of ever  attaining  any real  investment
standing.

     Moody's  applies  numerical  modifiers  1, 2 and 3 in each  generic  rating
category  from Aa through B. The modifier 1 indicates  that the bond being rated
ranks in the higher end of its generic rating category; the modifier 2 indicates
a mid-range ranking;  and the modifier 3 indicates a ranking in the lower end of
that generic rating category.

SHORT SALES

     A fund may  engage in short  sales if, at the time of the short  sale,  the
fund owns or has the right to acquire an equal amount of the security being sold
short.

     In a short sale,  the seller does not  immediately  deliver the  securities
sold and is said to have a short  position in those  securities  until  delivery
occurs.  To make delivery to the  purchaser,  the executing  broker  borrows the
securities being sold short on behalf of the seller. While the short position is
maintained,  the seller  collateralizes its obligation to deliver the securities
sold  short in an  amount  equal  to the  proceeds  of the  short  sale  plus an
additional  margin amount  established  by the Board of Governors of the Federal
Reserve.  If a fund  engages in a short sale,  the  collateral  account  will be
maintained by the fund's custodian.  While the short sale is open, the fund will
maintain in a segregated  custodial account an amount of securities  convertible
into or exchangeable for such equivalent securities at no additional cost. These
securities would constitute the fund's long position.

     A fund may make a short sale, as described above, when it wants to sell the
security  it owns at a  current  attractive  price,  but  also  wishes  to defer
recognition  of gain or loss for federal income tax purposes and for purposes of
satisfying certain tests applicable to regulated  investment companies under the
Internal  Revenue  Code.  In such a case,  any future  losses in the fund's long
position should be reduced by a gain in the short position.  The extent to which
such gains or losses are reduced  would  depend upon the amount of the  security
sold  short  relative  to the  amount  the  fund  owns.  There  will be  certain
additional  transaction  costs  associated  with short sales,  but the fund will
endeavor  to offset  these costs with  income  from the  investment  of the cash
proceeds of short sales.

PORTFOLIO TURNOVER

     In order to achieve its investment objective, the manager will purchase and
sell securities  without regard to the length of time the security has been held
and, accordingly,  it can be expected that the rate of portfolio turnover may be
substantial.

     The funds intend to purchase a given security whenever  management believes
it will contribute to the stated  objective of a fund, even if the same security
has only recently been sold. In selling a given  security,  the manager keeps in
mind that (1) profits from sales of securities  held less than three months must
be limited in order to meet the  requirements  of  Subchapter  M of the Internal
Revenue Code, and (2) profits from sales of securities are taxed to shareholders
as ordinary income. Subject to those considerations, the corporation will sell a
given  security,  no  matter  for how long or for how short a period it has been
held in the portfolio, and no matter whether the sale is at a gain or at a loss,
if the  management  believes  that  it is not  fulfilling  its  purpose,  either
because, among other things, it did not live up to management's expectations, or
because it may be replaced with another  security  holding greater  promise,  or
because it has  reached  its  optimum  potential,  or because of a change in the
circumstances  of a  particular  company  or  industry  or in  general  economic
conditions, or because of some combination of such reasons.

     When a  general  decline  in  security  prices is  anticipated,  a fund may
decrease  or  eliminate  entirely  its equity  position  and  increase  its cash
position,  and when a rise in price levels is  anticipated,  a fund may increase
its equity  position  and  decrease  its cash  position.  However,  it should be
expected that each fund will,  under most  circumstances,  be essentially  fully
invested in equity securities.

     Since investment decisions are based on the anticipated contribution of the
security in question to a fund's  objectives,  the rate of portfolio turnover is
irrelevant  when the  manager  believes  a change is in order to  achieve  those
objectives,  and a fund's annual  portfolio  turnover rate cannot be anticipated
and may be comparatively high. This disclosure regarding portfolio turnover is a
statement  of  fundamental  policy  and  may be  changed  only  by a vote of the
shareholders.


6                                                   American Century Investments




     Since the manager  does not take  portfolio  turnover  rate into account in
making investment  decisions,  (1) the manager has no intention of accomplishing
any  particular  rate of  portfolio  turnover,  whether high or low, and (2) the
portfolio  turnover  rates should not be considered as a  representation  of the
rates that will be attained in the future.

     The Board of  Directors  has  established  four  standing  committees:  the
Executive  Committee,  the Audit  Committee,  the  Compliance  Committee and the
Nominating Committee.

     Messrs.  Stowers Jr.,  Stowers III and Lundgaard  constitute  the Executive
Committee of the Board of Directors. The committee performs the functions of the
Board of Directors between meetings of the Board,  subject to the limitations on
its power set out in the  Maryland  Corporation  Law,  and  except  for  matters
required by the Investment Company Act to be acted upon by the whole Board.

     Messrs.   Lundgaard  (chairman),   Doering  and  Hock  and  Ms.  Strandjord
constitute the Audit  Committee.  The functions of the Audit  Committee  include
recommending the engagement of the funds' inde-

pendent auditors,  reviewing the arrangements for and scope of the annual audit,
reviewing  comments  made by the  independent  auditors with respect to internal
controls  and  the  considerations  given  or the  corrective  action  taken  by
management and reviewing nonaudit services provided by the independent auditors.

     Messrs.  Brown  (chairman),  Pratt and  Silver  constitute  the  Compliance
Committee.  The  functions of the  Compliance  Committee  include  reviewing the
results of the funds' compliance  testing program,  reviewing  quarterly reports
from  the  manager  to  the  Board  regarding  various  compliance  matters  and
monitoring  the  implementation  of the  funds'  Code of Ethics,  including  any
violations thereof.

     The Nominating  Committee has as its principal role the  consideration  and
recommendation  of  individuals  for  nomination  as  directors.  The  names  of
potential  director  candidates  are drawn from a number of  sources,  including
recommendations  from members of the Board,  management and  shareholders.  This
committee  also reviews and makes  recommendations  to the Board with respect to
the composition of Board committees and other Board-related  matters,  including
its   organization,   size,   composition,   responsibilities,   functions   and
compensation.  The  members  of  the  nominating  committee  are  Messrs.  Pratt
(chairman), Lundgaard and Stowers III.

     The  Directors of the  corporation  also serve as Directors for other funds
advised by the  manager.  Each  Director  who is not an  "interested  person" as
defined in the  Investment  Company Act  receives for service as a member of the
Board of all six of such companies an annual  director's fee of $44,000,  and an
additional fee of $1,000 per regular Board meeting attended and $500 per special
Board meeting and committee meeting attended.  In addition,  those directors who
are not  "interested  persons" and serve as chairman of a committee of the Board
of Directors  receive an  additional  $2,000 for such  services.  These fees and
expenses  are  divided  among the six  investment  companies  based  upon  their
relative  net  assets.  Under the  terms of the  management  agreement  with the
manager, the funds are responsible for paying such fees and expenses.

     Set  forth  below  is the  aggregate  compensation  paid  for  the  periods
indicated by the funds and by the American Century family of funds as a whole to
each  Director who is not an  "interested  person" as defined in the  Investment
Company Act.

     Those Directors who are "interested  persons," as defined in the Investment
Company Act,  receive no fee as such for serving as a Director.  The salaries of
such individuals, who are also officers of the funds, are paid by the manager.

MANAGEMENT

     A description of the  responsibilities  and method of  compensation  of the
funds' investment manager, American Century Investment Management, Inc., appears
in the Prospectus under the caption, "Management."

     During the  fiscal  years  ended  November  30,  1996,  1995 and 1994,  the
management fees paid by  International  Growth to the manager were  $21,271,619,
$21,967,586   and   $22,155,449   on  average  net  assets  of   $1,289,561,744,
$1,240,949,990  and  $1,205,407,244.  During the fiscal years ended November 30,
1996 and 1995, and the period from April 1, 1994  (inception)  through  November
30, 1994, the  management  fees paid by  International  Discovery to the manager
were $4,421,277,  $2,260,979 and $957,116 on average net assets of $235,583,979,
$113,067,308 and $71,587,570.

     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


8                                                   American Century Investments




as long thereafter as its continuance is specifically approved at least annually
by (i) the  funds'  Board  of  Directors,  or by the vote of a  majority  of the
outstanding  votes (as defined in the  Investment  Company Act), and (ii) by the
vote of a  majority  of the  Directors  of the funds 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 funds' Board of Directors, or by a vote of
a  majority  of the  funds'  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 funds or its shareholders for anything other than willful  misfeasance,  bad
faith, gross negligence or reckless disregard of its obligations or duties.

     The  management  agreement also provides that the manager and its officers,
directors 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 funds and also for other
clients  advised by the manager.  Investment  decisions  for the funds 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 in different amounts and
at  different  times for more than one but less than all  clients.  In addition,
purchases  or sales of the same  security may be made for two or more clients on
the same date.  Such  transactions  will be allocated  among clients in a manner
believed by  Investors  Research  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 a fund.

     The  manager  may  aggregate  purchase  and sale  orders of the funds  with
purchase  and sale orders of its other  clients when the manager  believes  that
such aggregation  provides the best execution for the funds. The funds' Board of
Directors has approved the policy of the manager with respect to the aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the funds  participate 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  funds  unless  it
believes such  aggregation is consistent with its duty to seek best execution on
behalf  of the  funds 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 funds,  on February  28, 1997,  the manager was
acting  as an  investment  advisor  to 12  institutional  accounts  and to  five
registered investment  companies,  American Century Mutual Funds, Inc., American
Century Premium  Reserves,  Inc.,  American  Century Capital  Portfolios,  Inc.,
American Century Strategic Asset Allocations, Inc. and American Century
Variable Portfolios, Inc.

     American  Century  Services   Corporation   provides  physical  facilities,
including  computer  hardware  and software and  personnel,  for the  day-to-day
administration  of the funds  and of the  manager.  The  manager  pays  American
Century Services Corporation for such services.

     As  stated  in the  Prospectus,  all  of  the  stock  of  American  Century
Services Corporation and American Century Investment  Management,  Inc. is owned
by American Century Companies, Inc.

CUSTODIANS

     UMB Bank, N.A., 10th and Grand,  Kansas City,  Missouri 64105, and Commerce
Bank, N.A. 1000 Walnut, Kansas City, Missouri 64105, each serves as custodian of
the  assets  of the  funds.  The  custodians  take no part  in  determining  the
investment  policies of the funds or in deciding which  securities are purchased
or sold by the funds. The funds,  however,  may invest in certain obligations of
the  custodians  and may  purchase  or sell  certain  securities  from or to the
custodians.

INDEPENDENT AUDITORS

At a  meeting  held  on  December  12,  1996,  the  Board  of  Directors  of the
corporation  appointed  Deloitte & Touche LLP, 1010 Grand  Avenue,  Kansas City,
Missouri


Statement of Additional Information                                            9




64106,  as the  independent  auditors  of the  funds to  examine  the  financial
statements  of the funds for the fiscal  year  ending  November  30,  1997.  The
appointment of Deloitte & Touche was  recommended by the Audit  Committee of the
Board of Directors.  As the independent auditors of the funds, Deloitte & Touche
will provide services  including (1) audit of the annual  financial  statements,
(2) assistance and consultation in connection with SEC filings and (3) review of
the annual federal income tax return filed for each fund by American Century.

     Ernst & Young LLP, One Kansas City Place,  1200 Main  Street,  Kansas City,
Missouri 64105, served as independent auditors for the funds for the fiscal year
ended November 30, 1996.

     Baird,  Kurtz & Dobson,  City Center Square,  Suite 2700, 1100 Main Street,
Kansas City, Missouri 64105, served as independent accountants for the funds and
examined the financial statements of the funds for all fiscal years ending prior
to December 1, 1995.

CAPITAL STOCK

     The funds' capital stock is described in the Prospectus  under the heading,
"Further Information About American Century."

     The  corporation  currently  has three series of shares  outstanding.  Each
series of shares is  further  divided  into four  classes.  The funds may in the
future  issue  additional  series or  classes  of  shares  without a vote of the
shareholders.  The assets  belonging  to each series or class of shares are held
separately by the  custodian and the shares of each series or class  represent a
beneficial  interest  in the  principal,  earnings  and  profits  (or losses) of
investment  and other  assets  held for that  series or class.  Your rights as a
shareholder  are the  same  for all  series  or  classes  of  securities  unless
otherwise stated. Within their respective series or class, all shares have equal
redemption  rights.  Each share, when issued, is fully paid and  non-assessable.
Each share,  irrespective  of series or class,  is entitled to one vote for each
dollar of net asset value represented by such share on all questions.

     In  the  event  of  complete  liquidation  or  dissolution  of  the  funds,
shareholders of each series or class of shares shall be entitled to receive, pro
rata, all of the assets less the liabilities of that series or class.

     As of February 28, 1997, 10% of the outstanding shares of Twentieth Century
International  Growth  were  owned of record  by  Charles  Schwab & Co.  Special
Custody Account For Exclusive Benefit of Customers-Reinvest.

MULTIPLE CLASS STRUCTURE

     The  funds'  Board of  Directors  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 four classes of shares:  an Investor  Class,  an
Institutional Class, a Service Class and an Advisor Class.

     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, Service 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  management fee. In addition to the management fee,
however,  Service  Class  shares are  subject  to a  Shareholder  Services  Plan
(described  below),  and the  Advisor  Class  shares  are  subject  to a  Master
Distribution and Shareholder  Services Plan (also described  below).  Both plans
have been adopted by the funds' Board of Directors  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  Directors  and  approved  by its  shareholders.
Pursuant to such rule,  the Board of Directors and initial  shareholders  of the
funds'  Service  Class and  Advisor  Class  have  approved  and  entered  into a
Shareholder  Services  Plan,  with  respect to the Service  Class,  and a Master
Distribution  and  Shareholder  Services Plan, with respect to the Advisor Class
(collectively, the "Plans"). Both Plans are described below.


10                                                  American Century Investments





     In adopting  the Plans,  the Board of  Directors  (including  a majority of
directors  who are not  "interested  persons"  of the funds [as  defined  in the
Investment Company Act],  hereafter referred to as the "independent  directors")
determined  that there was a reasonable  likelihood that the Plans would benefit
the funds and the shareholders of the affected classes.  Pursuant to Rule 12b-1,
information  with respect to revenues and expenses  under the Plans is presented
to the Board of Directors quarterly for its consideration in connection with its
deliberations as to the continuance of the Plans.  Continuance of the Plans must
be approved by the Board of Directors  (including a majority of the  independent
directors)  annually.  The  Plans  may be  amended  by a vote  of the  Board  of
Directors (including a majority of the independent  directors),  except that the
Plans 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 Plans terminate  automatically in the event of an assignment and may
be terminated upon a vote of a majority of the independent  directors 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.

SHAREHOLDER SERVICES PLAN

     As described in the Prospectus, the funds' Service Class of shares are 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.   In  such  circumstances,   certain
recordkeeping  and  administrative  services  that are  provided  by the  funds'
transfer  agent for the Investor Class  shareholders  may be performed by a plan
sponsor  (or its agents) or by a  financial  intermediary.  To enable the funds'
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 Service Class shares
and the funds'  Board of  Directors  has adopted a  Shareholder  Services  Plan.
Pursuant  to the  Shareholder  Services  Plan,  the Service  Class  shares pay a
shareholder  services fee of 0.25%  annually of the aggregate  average daily net
assets of the funds' Service Class shares.

     American Century Investment Services,  Inc. (the "Distributor") enters into
contracts  with  each  financial  intermediary  for  the  provision  of  certain
shareholder  services and utilizes the shareholder  services fees received under
the Shareholder Services Plan to pay for such services. Payments may be made for
a variety  of  shareholder  services,  including,  but are not  limited  to, (1)
receiving, aggregating and processing purchase, exchange and redemption requests
from beneficial  owners  (including  contract owners of insurance  products that
utilize  the  funds as  underlying  investment  media)  of  shares  and  placing
purchase,  exchange and redemption  orders with the  Distributor;  (2) providing
shareholders  with a service that invests the assets of their accounts in shares
pursuant to specific or  pre-authorized  instructions;  (3) processing  dividend
payments from a fund on behalf of  shareholders  and assisting  shareholders  in
changing dividend options, account designations and addresses; (4) providing and
maintaining  elective  services  such as wire transfer  services;  (5) acting as
shareholder of record and nominee for beneficial owners; (6) maintaining account
records  for   shareholders   and/or  other  beneficial   owners;   (7)  issuing
confirmations  of  transactions;  (8)  providing  subaccounting  with respect to
shares  beneficially  owned by  customers  of third  parties  or  providing  the
information  to a fund as necessary  for such  subaccounting;  (9) preparing and
forwarding   shareholder   communications  from  the  funds  (such  as  proxies,
shareholder  reports,  annual and semiannual  financial statements and dividend,
distribution and tax notices) to shareholders  and/or other  beneficial  owners;
(10) providing other similar  administrative  and sub-transfer  agency services;
and (11)  paying  "service  fees"  for the  provision  of  personal,  continuing
services to investors, as contemplated by the Rules of Fair Practice of the NASD
(collectively  referred to as "Shareholder  Services").  Shareholder Services do
not include those activities and expenses that are primarily  intended to result
in the sale of additional shares of the funds.

MASTER DISTRIBUTION AND SHAREHOLDER SERVICES PLAN

     As  described  in the  Prospectus,  the funds'  Advisor  Class of shares is
also made available to participants


Statement of Additional Information                                           11




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 funds' shares in
various investment products or in connection with various financial services.

     As  with  the  Service  Class,  certain  recordkeeping  and  administrative
services that are provided by the funds'  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  provide  various  distribution
services.

     To enable the funds'  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 funds'  Board of  Directors  has
adopted a Master  Distribution and Shareholder  Services Plan (the "Distribution
Plan").  Pursuant to such Plan,  the Advisor Class shares pay the  Distributor a
fee of 0.50%  annually of the  aggregate  average daily net assets of the funds'
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,  (1) 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;  (2)  compensation to registered  representatives  or other
employees of  Distributor  who engage in or support  distribution  of the funds'
Advisor Class shares; (3) compensation to, and expenses  (including overhead and
telephone  expenses)  of,   Distributor;   (4)  the  printing  of  prospectuses,
statements  of  additional  information  and  reports  for other  than  existing
shareholders; (5) the preparation, printing and distribution of sales literature
and advertising  materials  provided to the funds'  shareholders and prospective
shareholders;  (6)  receiving  and  answering  correspondence  from  prospective
shareholders,  including  distributing  prospectuses,  statements  of additional
information and shareholder  reports;  (7) the providing of facilities to answer
questions  from  prospective  investors  about fund shares;  (8) complying  with
federal and state  securities  laws  pertaining to the sale of fund shares;  (9)
assisting  investors in completing  application forms and selecting dividend and
other  account  options;  (10) the providing of other  reasonable  assistance in
connection  with  the  distribution  of fund  shares;  (11) the  organizing  and
conducting  of  sales  seminars  and  payments  in  the  form  of  transactional
compensation or promotional incentives;  (12) profit on the foregoing;  (13) 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 (14)
such other distribution and services activities as the manager determines may be
paid for by the funds  pursuant to the terms of this Agreement and in accordance
with Rule 12b-1 of the Investment Company Act.

TAXES

     Each  fund has  elected  to be taxed  under  Subchapter  M of the  Internal
Revenue Code as a regulated investment company. If it qualifies,  it will not be
subject to U.S.  federal income tax (other than any tax resulting from investing
in passive foreign  investment  companies,  as discussed  below) on net ordinary
income and net capital gains,  which are distributed to its shareholders  within
certain time periods specified in the Code.  Amounts not distributed on a timely
basis  would be subject  to  federal  corporate  income  tax and  possibly  to a
nondeductible 4% excise tax.

     Distributions  by the funds from net  investment  income and net short-term
capital   gains  are   taxable  to   shareholders   as  ordinary   income.   The
dividend-received  deduction  available to corporate  shareholders for dividends
received  from a fund will apply to ordinary  income  distributions  only to the
extent  that they are  attributable  to the  fund's  dividend  income  from U.S.
corporations.  In addition, the dividends-received  deduction will be limited if
the shares  with  respect to which the  dividends  are  received  are treated as
debt-financed or are deemed to have been held less than 46 days by a fund.


12                                                  American Century Investments





     Distributions from net long-term capital gains are taxable to a shareholder
as long-term  capital gains regardless of the length of time the shares on which
such  distributions  are  paid  have  been  held  by the  shareholder.  However,
shareholders  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 the shareholder
with respect to such shares.

     Income  from  foreign  securities  purchased  by a fund may be reduced by a
withholding  tax at the source.  If, as of the end of any fiscal year, more than
50% of the assets of a fund are invested in securities of foreign  corporations,
the fund may make an  election  that will result in the  shareholder  having the
option to elect either to deduct their pro rata share of the foreign  taxes paid
by the fund or to use their pro rata share of the foreign taxes paid by the fund
in calculating the foreign tax credit to which they are entitled.  Distributions
by a fund  will be  treated  as U.S.  source  income  for  purposes  other  than
computing the foreign tax credit limitation.

     If a fund invests in the securities of certain foreign  investment funds or
trusts called passive foreign investment  companies,  the fund may be subject to
federal corporate income taxation on a portion of any "excess distribution" with
respect to, or gain from the disposition of, such  securities.  The tax would be
determined by allocating such distribution or gain ratability to each day of the
fund's holding period for the stock.  The  distribution  or gain so allocated to
any  taxable  year of the  fund,  other  than  the  taxable  year of the  excess
distribution for disposition, would be taxed to the fund at the highest marginal
rate in effect  for such  year,  and the tax would be  further  increased  by an
interest  charge.  Any amount of  distribution  or gain allocated to the taxable
year of the distribution or disposition  would be included in the fund's taxable
income. In the alternative,  the fund may elect to recognize cumulative gains on
such  investments  as of the  last day of its  fiscal  year  and  distribute  to
shareholders.

     Redemption  of shares of a fund will be a taxable  transaction  for federal
income tax purposes,  and shareholders will generally  recognize 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.

     In addition to the federal income tax consequences described above relating
to an  investment  in a fund,  there  may be other  federal,  state or local tax
considerations  that depend upon the circumstances of each particular  investor.
Prospective  shareholders are therefore urged to consult their tax advisors with
respect to the effect of this investment on their own specific situations.

BROKERAGE

     Under the  management  agreement  between  the funds and the  manager,  the
manager  has the  responsibility  of  selecting  brokers  to  execute  portfolio
transactions.  The  funds'  policy is to secure  the most  favorable  prices and
execution  of orders on its  portfolio  transactions.  So long as that policy is
met, the manager may take into  consideration  the factors  discussed under this
caption when selecting brokers.

     The manager receives statistical and other information and services without
cost from  brokers and  dealers.  The manager  evaluates  such  information  and
services,  together with all other  information that it may have, in supervising
and managing the investments of the funds. Because such information and services
may vary in amount,  quality  and  reliability,  their  influence  in  selecting
brokers varies from none to very  substantial.  The manager proposes to continue
to place some of the funds'  brokerage  business  with one or more  brokers  who
provide information and services.  Such information and services provided to the
manager  will be in  addition  to and not in lieu  of  services  required  to be
performed  for the funds by the manager.  The manager  does not utilize  brokers
that  provide  such  information  and  services  for the purpose of reducing the
expense of providing required services to the funds.


Statement of Additional Information                                           13




     In the fiscal years ended November 30, 1996,  1995 and 1994,  International
Growth paid brokerage  commissions in the amount of $9,717,846,  $12,351,904 and
$18,168,517.  In the fiscal  years ended  November  30,  1996 and 1995,  and the
period from April 1, 1994 (inception)  through November 30, 1994,  International
Discovery paid brokerage commissions in the amount of $2,886,323, $1,434,299 and
$901,470.

     The brokerage  commissions paid by the funds may exceed those which another
broker might have charged for  effecting the same  transactions,  because of the
value of the brokerage and research  services  provided by the broker.  Research
services  furnished  by  brokers  through  whom  the  funds  effects  securities
transactions  may be used by the manager in servicing all of its  accounts,  and
not all such  services may be used by the manager in managing the  portfolios of
the funds.

     The  staff of the SEC has  expressed  the view  that  the  best  price  and
execution  of  over-the-counter  transactions  in  portfolio  securities  may be
secured by dealing directly with principal  market makers,  thereby avoiding the
payment of compensation to another broker. In certain  situations,  the officers
of the funds and the manager believe that the facilities,  expert  personnel and
technological systems of a broker enable the funds to secure as good a net price
by dealing with a broker instead of a principal market maker, even after payment
of  the   compensation   to  the  broker.   The  funds   normally   place  their
over-the-counter transactions with principal market makers, but also may deal on
a brokerage basis when utilizing electronic trading networks or as circumstances
warrant.

PERFORMANCE ADVERTISING

FUND PERFORMANCE

     Individual fund  performance  may be compared to various indices  including
the  Standard & Poor's  500 Index,  the Dow Jones  World  Index,  the IFC Global
Composite Index and the Morgan Stanley Capital International Europe,  Australia,
Far East EAFE(R) Index (EAFE Index).

     The  following  tables set forth the  average  annual  total  return of the
Investor  Class of the funds for the periods  indicated.  Average  annual  total
return is  calculated  by  determining  cumulative  total  return for the stated
period and then  computing  the annual  compound  return that would  produce the
cumulative  total return if the funds'  performance  had been constant over that
period.  Cumulative  total return  includes  all  elements of return,  including
reinvestment of dividends and capital gains distributions.  Annualization of the
funds'  return  assumes  that the  partial  year  performance  will be  constant
throughout the period.  Actual returns through the period may be greater or less
than the annualized data.

its inception through November 30, 1996, was 96.97%.  International  Discovery's
cumulative  total return for the period from its inception  through November 30,
1996, was 52.83%.

REDEMPTIONS IN KIND

     The funds'  policy with regard to large  redemptions  is  described  in the
Prospectus under the heading "Special Requirements for Large Redemptions."

     The  corporation  has  elected  to be  governed  by Rule  18f-1  under  the
Investment  Company  Act,  pursuant to which the funds are  obligated  to redeem
shares  solely in cash up to the lesser of $250,000 or 1% of the net asset value
of a fund  during  any  90-day  period  for any one  shareholder.  If shares are
redeemed in kind,  the  redeeming  shareholder  might incur  brokerage  costs in
converting the assets to cash. The securities  delivered will be selected at the
sole  discretion  of the  manager.  Such  securities  will  not  necessarily  be
representative  of the entire  portfolio and may be securities  that the manager
regards as least desirable.  The method of valuing portfolio  securities used to
make  redemptions  in kind will be the same as the method of  valuing  portfolio
securities  described  in the  prospectus  under the caption "How Share Price is
Determined,"  and such valuation will be made as of the same time the redemption
price is determined.

HOLIDAYS

     The funds do not determine the net asset value of their shares on days when
the New York Stock  Exchange  is closed.  Currently,  the  Exchange is closed on
Saturdays  and Sundays,  and on holidays,  namely New Year's Day,  Martin Luther
King Jr. Day,  Presidents'  Day, Good Friday,  Memorial Day,  Independence  Day,
Labor Day, Thanksgiving and Christmas.
