SPECIAL MEETING OF SHAREHOLDERS

At a Special Meeting of Shareholders held on July 30, 1997,  shareholders of the
Funds approved, among other things, a new Management Agreement between the Funds
with American Century Investment Management,  Inc. This new Management Agreement
will  become  effective  on August 1, 1997,  and  replaces  the  Funds'  current
investment advisory agreement with Benham Management  Corporation,  an affiliate
of American Century Investment Management, Inc. At the meeting,  shareholders of
the  Funds  also  ratified  the  selection  of  Coopers  &  Lybrand  LLP  as the
independent  auditors  for each  Fund's  current  fiscal year and  approved  the
adoption of  standardized  investment  limitations  by  amending or  eliminating
certain of the Funds' fundamental investment limitations.  The changes resulting
from the  Special  Meeting of  Shareholders  are  reflected  in this  Prospectus
Supplement and in the revised Statement of Additional Information of the Funds.

AVERAGE WEIGHTED MATURITY

On page 13,  under  the  heading  "Portfolio  Investment  Quality  and  Maturity
Guidelines--Money  Market  Funds,"  item (2) is deleted  and  replaced  with the
following:

RULE 144A SECURITIES

On page 19, the last sentence of the last paragraph is deleted and the following
additional paragraph is added:

     No Fund may invest  more than 15% (10% for the Money  Market  Funds) of its
net assets in illiquid securities  (securities that may not be sold within seven
days at approximately  the price used in determining the net asset value of Fund
shares).

INVESTMENT MANAGEMENT

On page 30, the first  paragraph in the  subsection  "Investment  Management" is
deleted and replaced with the following:

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

On page 31, the first full paragraph is deleted,  and the last paragraph  before
the  subsection  heading  "Code of  Ethics"  is deleted  and  replaced  with the
following:

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

     For the services  provided to the Funds, the Manager receives a monthly fee
based on a percentage of the average net assets of each Fund. The annual rate at
which this fee is assessed is determined monthly in a two-step process: First, a
fee rate  schedule  is  applied  to the  assets  of all of the funds in a Fund's
investment  category which are managed by the Manager (the "Investment  Category
Fee"). There are three investment categories: Money Market Funds, Bond Funds and
Equity Funds.  Second,  a separate fee rate schedule is applied to the assets of
all of the  mutual  funds  managed  by the  Manager  (the  "Complex  Fee").  The
Investment  Category  Fee and the  Complex Fee are then added to  determine  the
unified  management  fee  payable  by the Fund to the  Manager.  Currently,  the
Investment  Category  Fee for each of the Funds is an annual rate of the average
net  assets  of the  Fund as  follows:  California  Tax-Free  Money  Market  and
California  Municipal Money Market,  0.20%;  California  Limited-Term  Tax-Free,
California   Intermediate-Term  Tax-Free,   California  Long-Term  Tax-Free  and
California  Insured  Tax-Free,  0.22%;  and California  High-Yield,  0.25%.  The
Complex Fee is  currently an annual rate of 0.30% of the average net assets of a
Fund. Further  information about the calculation of the annual management fee is
contained in the Statement of Additional Information.

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

TRANSFER AND ADMINISTRATIVE SERVICES

On page 32, the first paragraph under the heading  "Transfer and  Administrative
Services" is deleted and replaced with the following:

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

EXPENSES

On page 32, the subsection called "Expenses" is deleted.

Statement of Additional Information                                          1


INVESTMENT POLICIES AND TECHNIQUES

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

MUNICIPAL NOTES

     Municipal  notes are issued by state and local  governments  or  government
entities to provide short-term capital or to meet cash flow needs.

     Tax  Anticipation  Notes (TANs) are issued in  anticipation of seasonal tax
revenues,  such as ad valorem property,  income, sales, use, and business taxes,
and are payable from these future  taxes.  Tax  anticipation  notes  usually are
general  obligations  of the  issuer.  General  obligations  are  secured by the
issuer's  pledge of its full  faith and  credit  (i.e.,  taxing  power)  for the
payment of principal and interest.

     Revenue  Anticipation  Notes  (RANs) are issued with the  expectation  that
receipt  of  future  revenues,  such as  federal  revenue  sharing  or state aid
payments,  will be  used  to  repay  the  notes.  Typically,  these  notes  also
constitute general obligations of the issuer.

     Bond  Anticipation  Notes  (BANs) are issued to provide  interim  financing
until long-term  financing can be arranged.  In most cases,  the long-term bonds
provide the money for repayment of the notes.

     Tax-Exempt  Commercial Paper is an obligation with a stated maturity of 365
days or less issued to finance seasonal cash flow needs or to provide short-term
financing in anticipation of longer-term financing.

     Revenue Anticipation  Warrants,  or reimbursement  warrants,  are issued to
meet the cash flow needs of the State of  California at the end of a fiscal year
and in the early weeks of the following  fiscal year. These warrants are payable
from  unapplied  money in the State's  General  Fund,  including the proceeds of
revenue  anticipation notes issued following  enactment of a State budget or the
proceeds of refunding warrants issued by the State.

MUNICIPAL BONDS

     Municipal bonds, which generally have maturities of more than one year when
issued,  are designed to meet longer-term  capital needs.  These securities have
two principal classifications: general obligation bonds and revenue bonds.

     General  Obligation  (GO)  Bonds are issued by  states,  counties,  cities,
towns, and regional  districts to fund a variety of public  projects,  including
construction  of and  improvements  to  schools,  highways,  and water and sewer
systems.  General  obligation  bonds are backed by the  issuer's  full faith and
credit based on its ability to levy taxes for the timely payment of interest and
repayment  of  principal,  although  such  levies  may  be  constitutionally  or
statutorily limited as to rate or amount.

     Revenue  Bonds are not  backed by an  issuer's  taxing  authority;  rather,
interest  and  principal  are  secured  by the net  revenues  from a project  or
facility.  Revenue  bonds are issued to  finance a variety of capital  projects,
including  construction or refurbishment of utility and waste disposal  systems,
highways, bridges, tunnels, air and sea port facilities, schools, and hospitals.
Many  revenue  bond  issuers  provide  additional  security  in  the  form  of a
debt-service  reserve  fund that may be used to make  payments of  interest  and
repayments  of  principal  on  the  issuer's  obligations.   Some  revenue  bond
financings are further  protected by a state's  assurance  (without  obligation)
that it will make up deficiencies in the debt-service reserve fund.

     Industrial  Development Bonds (IDBs), a type of revenue bond, are issued by
or on behalf of public  authorities to finance  privately  operated  facilities.
These bonds are used to finance business, manufacturing,  housing, athletic, and
pollution  control  projects,  as well as public facilities such as mass transit
systems, air and sea port facilities,  and parking garages.  Payment of interest
and  repayment  of  principal  on an IDB  depend  solely on the  ability  of the
facility's user to meet financial obligations, and on the pledge, if any, of the
real or personal property  financed.  The interest earned on IDBs may be subject
to the federal alternative minimum tax.

VARIABLE- AND FLOATING-RATE DEMAND OBLIGATIONS

     The Funds may buy variable- and floating-rate demand obligations (VRDOs and
FRDOs).  These obligations carry rights that permit holders to demand payment of
the unpaid principal plus accrued  interest,  from the issuers or from financial
intermediaries.


2                                                American Century Investments


Floating-rate  securities  have interest  rates that change  whenever there is a
change in a  designated  base  rate;  variable-rate  instruments  provide  for a
specified, periodic adjustment in the interest rate, which typically is based on
an index.  These rate  formulas are designed to result in a market value for the
VRDO or FRDO that approximates par value.

OBLIGATIONS WITH TERM PUTS ATTACHED

     Each Fund may invest in fixed-rate bonds subject to third party puts and in
participation  interests  in such  bonds  held by a bank in trust or  otherwise.
These bonds and  participation  interests have tender options or demand features
that  permit  the Funds to tender  (or put)  their  bonds to an  institution  at
periodic intervals and to receive the principal amount thereof.

     American Century Investment  Management,  Inc. (the "Manager"),  the Funds'
investment  advisor,  expects that the Funds will pay more for  securities  with
puts attached than for securities without these liquidity features.  The Manager
may buy securities with puts attached to keep a Fund fully invested in municipal
securities while maintaining  sufficient  portfolio liquidity to meet redemption
requests or to facilitate  management of the Funds' investments.  To ensure that
the interest on municipal securities subject to puts is tax-exempt to the Funds,
the  Manager  limits  the  Funds'  use of puts  in  accordance  with  applicable
interpretations and rulings of the Internal Revenue Service (IRS).

     Because it is  difficult  to  evaluate  the  likelihood  of exercise or the
potential  benefit of a put, puts normally will be determined to have a value of
zero,  regardless  of whether  any  direct or  indirect  consideration  is paid.
Accordingly,  puts as separate  securities are not expected to affect the Funds'
weighted  average  maturities.  When a Fund has paid for a put, the cost will be
reflected as unrealized  depreciation on the underlying  security for the period
the put is held. Any gain on the sale of the underlying security will be reduced
by the cost of the put.

     There is a risk that the seller of a put will not be able to repurchase the
underlying  obligation  when (or if) a Fund  attempts  to  exercise  the put. To
minimize such risks, the Funds will purchase obligations with puts attached only
from sellers deemed creditworthy by the Manager under the direction of the Board
of Trustees.

TENDER OPTION BONDS

     Tender  option  bonds  (TOBs)  were  created  to  increase  the  supply  of
high-quality, short-term tax-exempt obligations, and thus they are of particular
interest to the Money Market Funds. However, any of the Funds may purchase these
instruments.

     TOBs  are  created  by  municipal  bond  dealers  who  purchase   long-term
tax-exempt bonds in the secondary market,  place the certificates in trusts, and
sell interests in the trusts with puts or other liquidity  guarantees  attached.
The credit quality of the resulting synthetic short-term  instrument is based on
the guarantor's short-term rating and the underlying bond's long-term rating.

     There is some risk that a remarketing  agent will renege on a tender option
agreement if the underlying bond is downgraded or defaults. Because of this, the
Manager  monitors the credit quality of bonds underlying the Funds' TOB holdings
and  intends  to sell or put back any TOB if the rating on its  underlying  bond
falls  below the  second-highest  rating  category  designated  by a  nationally
recognized statistical rating agency (a "rating agency").

     The Manager also takes steps to minimize the risk that the Fund may realize
taxable   income  as  a  result  of  holding  TOBs.   These  steps  may  include
consideration  of (a) legal opinions  relating to the  tax-exempt  status of the
underlying  municipal bonds, (b) legal opinions relating to the tax ownership of
the underlying  bonds, and (c) other elements of the structure that could result
in taxable income or other adverse tax consequences.

     After  purchase,  the Manager  monitors  factors  related to the tax-exempt
status of the Fund's TOB  holdings in order to minimize  the risk of  generating
taxable income.

WHEN-ISSUED AND FORWARD COMMITMENT
AGREEMENTS

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

     When purchasing securities on a when-issued or forward commitment basis,
the Fund assumes the


Statement of Additional Information                                         3


rights  and  risks  of  ownership,  including  the  risks  of  price  and  yield
fluctuations.  While  the  Fund  will  make  commitments  to  purchase  or  sell
securities with the intention of actually  receiving or delivering  them, it may
sell the securities  before the settlement date if doing so is deemed  advisable
as a matter of investment strategy.

     In purchasing  securities on a when-issued or forward commitment basis, the
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash, cash equivalents,  or other appropriate liquid securities in
an amount  sufficient to meet the purchase price. When the time comes to pay for
the when-issued  securities,  the Fund will meet its obligations  with available
cash, through the sale of securities,  or, although it would not normally expect
to do so, by selling the  when-issued  securities  themselves  (which may have a
market  value  greater  or less than the  Fund's  payment  obligation).  Selling
securities to meet  when-issued or forward  commitment  obligations may generate
taxable capital gains or losses.

     The Funds may sell a  security  and at the same time make a  commitment  to
purchase the same or a comparable security at a future date and specified price.
Conversely,  the  Funds  may  purchase  a  security  and at the same time make a
commitment  to sell  the same or a  comparable  security  at a  future  date and
specified price. These types of transactions are executed simultaneously in what
are known as "dollar-rolls,"  "cash-and-carry"  or financing  transactions.  For
example,  a  broker-dealer  may seek to purchase a particular  security that the
Funds  own.  The  Funds  will  sell  that  security  to  the  broker-dealer  and
simultaneously  enter into a forward  commitment  agreement  to buy it back at a
future  date.  This type of  transaction  generates  income for the Funds if the
dealer is willing to execute the  transaction  at a favorable  price in order to
acquire a specific security.  In purchasing  "dollar-rolls" or  "cash-and-carry"
transactions,  the Fund will  maintain  until the  settlement  date a segregated
account consisting of cash, cash equivalents,  or high-quality liquid securities
in an amount sufficient to meet the purchase price.

     As an  operating  policy,  each Fund will not  commit  more than 50% of its
total assets to when-issued or forward commitment agreements. If fluctuations in
the value of securities  held cause more than 50% of a Fund's total assets to be
committed under when-issued or forward commitment  agreements,  the Manager need
not sell such  agreements,  but it will be restricted from entering into further
agreements  on behalf of the Fund until the  percentage  of assets  committed to
such agreements is below 50% of total assets.

MUNICIPAL LEASE OBLIGATIONS

     Each Fund may invest in municipal  lease  obligations.  These  obligations,
which may take the form of a lease,  an installment  purchase,  or a conditional
sale  contract,  are issued by state and local  governments  and  authorities to
acquire land and a wide  variety of equipment  and  facilities.  Generally,  the
Funds will not hold such  obligations  directly as a lessor of the  property but
will purchase a participation  interest in a municipal  lease  obligation from a
bank or other third party.

     Municipal leases frequently carry risks distinct from those associated with
general obligation or revenue bonds. State  constitutions and statutes set forth
requirements that states and  municipalities  must meet to incur debt. These may
include  voter  referenda,  interest rate limits,  or public sale  requirements.
Leases,  installment  purchases,  or conditional  sale contracts (which normally
provide for title to the leased  asset to pass to the  government  issuer)  have
evolved  as a way for  government  issuers  to acquire  property  and  equipment
without meeting  constitutional  and statutory  requirements for the issuance of
debt.

     Many leases and contracts include  nonappropriation  clauses, which provide
that the governmental issuer has no obligation to make future payments under the
lease  or  contract  unless  money is  appropriated  for  such  purposes  by the
appropriate  legislative  body on a yearly or other  periodic  basis.  Municipal
lease   obligations  also  may  be  subject  to  abatement  risk.  For  example,
construction  delays or  destruction of a facility as a result of an uninsurable
disaster  that  prevents  occupancy  could result in all or a portion of a lease
payment not being made.

     California  and its  municipalities  are the largest  issuers of  municipal
lease obligations in the United States.

INVERSE FLOATERS (VARIABLE-PRICE FUNDS)

     The Variable-Price Funds may hold inverse floaters. An inverse floater is a
type of derivative  that bears an interest  rate that moves  inversely to market
interest rates. As market interest rates rise, the interest rate on


4                                                American Century Investments


inverse floaters goes down, and vice versa.  Generally,  this is accomplished by
expressing  the interest rate on the inverse  floater as an  above-market  fixed
rate of interest, reduced by an amount determined by reference to a market-based
or bond-specific  floating interest rate (as well as by any fees associated with
administering the inverse floater program).

     Inverse floaters may be issued in conjunction with an equal amount of Dutch
Auction  floating-rate bonds (floaters),  or a market-based index may be used to
set the interest rate on these securities.  Floaters and inverse floaters may be
brought to market by a broker-dealer  who purchases  fixed-rate bonds and places
them in a trust or by an issuer seeking to reduce  interest  expenses by using a
floater/inverse floater structure in lieu of fixed-rate bonds.

     In the  case  of a  broker-dealer  structured  offering  (where  underlying
fixed-rate bonds have been placed in a trust), distributions from the underlying
bonds are  allocated  to floater and inverse  floater  holders in the  following
manner:

(i)  Floater  holders  receive  interest  based on rates set at a Dutch Auction,
     which  is  typically  held  every 28 to 35 days.  Current  and  prospective
     floater  holders  bid the  minimum  interest  rate that they are willing to
     accept on the  floaters,  and the interest  rate is set just high enough to
     ensure that all of the floaters are sold.

(ii) Inverse  floater  holders  receive all of the interest  that remains on the
     underlying bonds after floater interest and auction fees are paid.

     Procedures  for  determining  the interest  payment on floaters and inverse
floaters  brought to market directly by the issuer are comparable,  although the
interest  paid on the inverse  floaters is based on a presumed  coupon rate that
would have been  required  to bring  fixed-rate  bonds to market at the time the
floaters and inverse floaters were issued.

     Where inverse  floaters are issued in conjunction  with  floaters,  inverse
floater holders may be given the right to acquire the underlying security (or to
create a fixed-rate bond) by calling an equal amount of corresponding  floaters.
The underlying security may then be held or sold. However,  typically, there are
time  constraints  and other  limitations  associated  with any right to combine
interests and claim the underlying security.

     Floater holders subject to a Dutch Auction procedure  generally do not have
the right to "put back" their  interests to the issuer or to a third party. If a
Dutch  Auction  fails,  the floater  holder may be required to hold its position
until the underlying bond matures,  during which time interest on the floater is
capped at a predetermined rate.

     The secondary market for floaters and inverse floaters may be limited.  The
market value of inverse  floaters tends to be  significantly  more volatile than
fixed-rate  bonds.  The interest rates on inverse  floaters may be significantly
reduced, even to zero, if interest rates rise.

LOWER-QUALITY BONDS
(CALIFORNIA HIGH-YIELD MUNICIPAL)

     As indicated in the  Prospectus,  an investment  in  California  High-Yield
Municipal carries greater risk than an investment in the other Funds because the
Fund may invest without limitation in lower-rated bonds and unrated bonds judged
by  the  Manager  to  be of  comparable  quality  (collectively,  "lower-quality
bonds").

     While the  market  values of  higher-quality  bonds tend to  correspond  to
market interest rate changes,  the market values of lower-quality  bonds tend to
reflect the financial condition of their issuers.

     Projects  financed  through the issuance of  lower-quality  bonds are often
highly  leveraged.  The issuer's  ability to service its debt obligations may be
adversely affected by an economic  downturn,  a period of rising interest rates,
the issuer's inability to meet projected revenue forecasts,  or a lack of needed
additional financing.

     Lower-quality  bonds generally are unsecured and often are  subordinated to
other  obligations of the issuer.  These bonds  frequently have call or buy-back
features that permit the issuer to call or repurchase  the bond from the holder.
Premature disposition of a lower-quality bond due to a call or buy-back feature,
deterioration  of the  issuer's  creditworthiness,  or a  default  may  make  it
difficult  for the  Manager to manage the flow of income to the Fund,  which may
have negative tax implications for shareholders.

     The market for lower-quality bonds tends to be concentrated among a smaller
number of dealers  than the  market for  higher-quality  bonds.  This  market is
dominated by dealers and institutions (including mutual


Statement of Additional Information                                          5


funds),  rather than by  individuals.  To the extent  that a  secondary  trading
market for lower-quality  bonds exists, it may not be as liquid as the secondary
market for higher-quality  bonds.  Limited liquidity in the secondary market may
adversely  affect market  prices and hinder the Manager's  ability to dispose of
particular  bonds when it determines that it is in the best interest of the Fund
to do so.  Reduced  liquidity  may also hinder the  Manager's  ability to obtain
market  quotations for purposes of valuing the Fund's  portfolio and determining
its net asset value.

     The Manager  continually  monitors  securities to determine  their relative
liquidity.

     The Fund may incur expenses in excess of its ordinary operating expenses if
it becomes necessary to seek recovery on a defaulted lower-quality bond.

LIMITED-TERM SECURITIES (VARIABLE-PRICE FUNDS)

     Under certain  circumstances,  California  Long-Term  Tax-Free,  California
High-Yield  Municipal,  and California Insured Tax-Free may invest in short-term
municipal or U.S.  government  securities,  including  money market  instruments
(short-term  securities).  Except as otherwise required for temporary  defensive
purposes,  the Manager does not expect these Funds'  investments  in  short-term
securities to exceed 35% of total assets.  If a Fund invests in U.S.  government
securities,  a portion of dividends paid to shareholders  will be taxable at the
federal  level,  and may be  taxable at the state  level,  as  ordinary  income.
However,  the Manager  intends to minimize such  investments  and, when suitable
short-term  municipal  securities are  unavailable,  may allow the Funds to hold
cash to avoid generating taxable dividends.

     Pursuant to an exemptive order from the Securities and Exchange  Commission
(SEC),  each  Variable-Price  Fund may  invest up to 5% of its  total  assets in
shares of the Money Market Funds to facilitate cash management provided that the
investment is consistent with the Funds'  investment  policies and restrictions.
To avoid generating  dividend income subject to the federal  alternative minimum
tax (AMT), the Variable-Price Funds (excluding  California High-Yield Municipal)
will limit their Money Market Fund  investments  to  California  Tax-Free  Money
Market.  California  High-Yield  Municipal,  which  ordinarily  invests  in  AMT
securities,  may invest up to 5% of its total  assets in shares of either of the
Money Market Funds.

CONCENTRATION OF ASSETS IN OBLIGATIONS ISSUED TO FINANCE SIMILAR PROJECTS OR
FACILITIES

     From time to time, a significant portion of a Fund's assets may be invested
in  municipal  obligations  related to the extent that  economic,  business,  or
political developments affecting one of these obligations could affect the other
obligations in a similar manner.  For example,  if a Fund invested a significant
portion of its assets in utility bonds and a state or federal  government agency
or  legislative  body  promulgated  or  enacted  new  environmental   protection
requirements  for utility  providers,  projects  financed by utility bonds could
suffer as a class. Additional financing might be required to comply with the new
environmental  requirements,  and  outstanding  debt might be  downgraded in the
interim.  Among other  factors  that could  negatively  affect  bonds  issued to
finance  similar types of projects are state and federal  legislation  regarding
financing  for  municipal  projects,  pending  court  decisions  relating to the
validity  or  means  of  financing  municipal  projects,  material  or  manpower
shortages,  and  declining  demand for  projects or  facilities  financed by the
municipal bonds.

FUTURES AND OPTIONS (VARIABLE-PRICE FUNDS)

     Each  Variable-Price  Fund may enter into futures  contracts,  options,  or
options on futures  contracts.  Some  futures  and options  strategies,  such as
selling  futures,  buying puts,  and writing calls,  hedge a Fund's  investments
against price fluctuations.  Other strategies,  such as buying futures,  writing
puts, and buying calls,  tend to increase market exposure.  The Funds do not use
futures and options transactions for speculative purposes.

     Although  other  techniques  may be used to  control a Fund's  exposure  to
market fluctuations,  the use of futures contracts may be a more effective means
of hedging this exposure.  While a Fund pays brokerage commissions in connection
with opening and closing out futures  positions,  these costs are lower than the
transaction   costs  incurred  in  the  purchase  and  sale  of  the  underlying
securities.

     Futures contracts provide for the sale by one party and purchase by another
party of a specific  security  at a  specified  future  time and price.  Futures
contracts  are traded on  national  futures  exchanges.  Futures  exchanges  and
trading are regulated under the


6                                                 American Century Investments


Commodity  Exchange Act by the Commodity  Futures Trading  Commission  (CFTC), a
U.S. government agency. The Funds may engage in futures and options transactions
based on securities indexes such as the Bond Buyer Index of Municipal Bonds that
are consistent with the Fund's investment  objectives.  The Fund may also engage
in futures and options  transactions  based on specific  securities such as U.S.
Treasury bonds or notes.

     Bond Buyer Municipal Bond Index futures  contracts  differ from traditional
futures  contracts in that when  delivery  takes place,  no bonds change  hands.
Instead,  these  contracts  settle in cash at the spot market  value of the Bond
Buyer Municipal Bond Index.  Although other types of futures  contracts by their
terms call for actual  delivery or acceptance of the underlying  securities,  in
most cases the  contracts are closed out before the  settlement  date. A futures
position may be closed by taking an opposite  position in an identical  contract
(i.e.,  buying a contract  that has  previously  been sold or selling a contract
that has previously been bought).

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

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

     RISKS  RELATED TO FUTURES  AND  OPTIONS  TRANSACTIONS.  Futures and options
prices can be volatile,  and trading in these markets involves certain risks. If
the Manager  applies a hedge at an  inappropriate  time or judges  interest rate
trends incorrectly, futures and options strategies may lower a Fund's return.

     A Fund  could  suffer  losses if it were  unable to close out its  position
because of an illiquid  secondary  market.  Futures  contracts may be closed out
only on an exchange that provides a secondary  market for these  contracts,  and
there  is no  assurance  that a  liquid  secondary  market  will  exist  for any
particular futures contract at any particular time. Consequently,  it may not be
possible to close a futures  position when the Manager  considers it appropriate
or desirable to do so. In the event of adverse price movements,  a Fund would be
required to continue making daily cash payments to maintain its required margin.
If the Fund had insufficient cash, it might have to sell portfolio securities to
meet daily margin  requirements  at a time when the Manager  would not otherwise
elect to do so. In addition,  a Fund may be required to deliver or take delivery
of instruments  underlying  futures contracts it holds. The Manager will seek to
minimize  these risks by limiting  the  contracts  entered into on behalf of the
Funds to those traded on national futures  exchanges and for which there appears
to be a liquid secondary market.

     A Fund  could  suffer  losses if the  prices  of its  futures  and  options
positions were poorly  correlated with its other  investments,  or if securities
underlying futures contracts  purchased by a Fund had different  maturities than
those of the portfolio  securities being hedged. Such imperfect  correlation may
give rise to  circumstances in which a Fund loses money on a futures contract at
the same  time  that it  experiences  a  decline  in the  value of its  "hedged"
portfolio  securities.  A Fund could also lose margin  payments it has deposited
with a margin broker, if, for example, the broker became bankrupt.

     Most futures exchanges limit the amount of fluctuation permitted in futures
contract  prices during a single  trading day. The daily limit  establishes  the
maximum  amount that the price of a futures  contract may vary either up or down
from the previous day's settlement price at the end of the trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price  beyond  the  limit.  However,  the  daily  limit
governs only price movement during a particular trading


Statement of Additional Information                                          7


day and,  therefore,  does not limit potential  losses.  In addition,  the daily
limit may prevent liquidation of unfavorable positions.  Futures contract prices
have occasionally moved to the daily limit for several  consecutive trading days
with little or no trading,  thereby  preventing  prompt  liquidation  of futures
positions and subjecting some futures traders to substantial losses.

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

     Although  they do not  currently  intend to do so,  the Funds may write (or
sell) call options that obligate it to sell (or deliver) the option's underlying
instrument  upon  exercise of the option.  While the receipt of option  premiums
would  mitigate  the  effects of price  declines,  the Funds  would give up some
ability to participate in a price increase on the underlying security. If a Fund
were to engage in options transactions, it would own the futures contract at the
time a call were written and would keep the contract  open until the  obligation
to deliver it pursuant to the call expired.

     RESTRICTIONS   ON  THE  USE  OF  FUTURES   CONTRACTS   AND  OPTIONS.   Each
Variable-Price  Fund may enter into futures  contracts,  options,  or options on
futures  contracts.  Under the  Commodity  Exchange  Act,  a Fund may enter into
futures and options  transactions (a) for hedging purposes without regard to the
percentage of assets committed to initial margin and option premiums, or (b) for
other than hedging  purposes,  provided that assets  committed to initial margin
and option  premiums do not exceed 5% of the Fund's total assets.  To the extent
required by law, each Fund will set aside cash and appropriate  liquid assets in
a segregated  account to cover its obligations  related to futures contracts and
options.

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

MUNICIPAL BOND INSURERS
(CALIFORNIA INSURED TAX-FREE)

     Securities held by California  Insured  Tax-Free may be (a) insured under a
new-issue  insurance policy obtained by the issuer of the security,  (b) insured
under a secondary  market  insurance  policy purchased by the Fund or a previous
bond holder, or (c) insured under a "when-in-portfolio" policy held by the Fund.
The  following   paragraphs  provide  some  background  on  the  bond  insurance
organizations  most  frequently  relied upon for municipal bond insurance in the
United States.

     AMBAC  Indemnity  Corporation  (AMBAC  Indemnity) is a  Wisconsin-domiciled
stock insurance  corporation with admitted assets of approximately  $2.1 billion
(unaudited) and statutory capital of approximately  $1.2 billion  (unaudited) as
of  December  31,  1994.   Statutory   capital  consists  of  AMBAC  Indemnity's
policyholders'  surplus and statutory contingency reserve.  AMBAC Indemnity is a
wholly  owned  subsidiary  of  AMBAC  Inc.,  a  publicly-held  company.  Moody's
Investors  Service,  Inc. (Moody's) and Standard & Poor's Corporation (S&P) have
rated AMBAC Indemnity's claims-paying ability Aaa and AAA, respectively.

     Financial Guaranty Insurance Company (FGIC) is a wholly owned subsidiary of
FGIC  Corporation,  a Delaware  corporation with admitted assets of $2.1 billion
and a statutory capital base of $1.1 billion as of December 31, 1994.  Statutory
capital  consists of total capital and surplus as well as  contingency  reserve.
FGIC's claims-paying  ability was rated Aaa/AAA/AAA by Moody's,  S&P, and Fitch,
respectively.

     Municipal  Bond  Investors  Assurance  Corporation  (MBIA)  is  a  monoline
insurance company organized as a New York corporation.  As of December 31, 1994,
MBIA  (consolidated)  had  admitted  assets of $3.4 billion  (unaudited),  total
liabilities of $1.6 billion  (unaudited),  and total capital and surplus of $1.7
billion (unaudited).  All bond issues insured by MBIA are rated "Aaa" by Moody's
and all  short-term  loans insured by MBIA  "MIG-1." All bond issues  insured by
MBIA are rated "AAA" by S&P.

SPECIAL CONSIDERATIONS REGARDING CALIFORNIA
MUNICIPAL SECURITIES

     As  briefly  discussed  in the  Prospectus,  the Funds are  susceptible  to
political,  economic,  and  regulatory  events that affect issuers of California
municipal  obligations.  These include  possible  adverse  affects of California
constitutional  amendments,  legislative measures, voter initiatives,  and other
matters described below.

     The  following  information  about risk  factors is provided in view of the
Funds'  policies  of   concentrating   their  assets  in  California   municipal
securities.  This information is based on recent official statements relating to
securities  offerings of California  issuers,  although it does not constitute a
complete  description  of the risk  associated  with  investing in securities of
these issuers.  While the Manager has not independently verified the information
contained  in  the  official  statements,  it  has  no  reason  to  believe  the
information is inaccurate.

ECONOMIC OVERVIEW

     California's  economy  is the  largest  among the 50 states  and one of the
largest  in the world.  The  State's  population  of over 30 million as of 1990,
representing approximately 12% of the U.S. population, grew by 27% in the 1980s.
Total  personal  income,  an  estimated  $703  billion  in 1994,  accounted  for
approximately  12% of personal  income  nationwide.  In 1994,  total  employment
increased 260,000 from 1993 levels of 13.8 million. Jobs are concentrated in the
service, trade, and manufacturing sectors.

     From  mid-1990  to late  1993,  the  State's  economy  suffered  its  worst
recession since the 1930s, with recovery starting later than for the nation as a
whole. The State has experienced the worst job losses of any post-war recession.
Prerecession  job levels may not be  realized  until near the end of the decade.
The largest job losses have been in Southern California,  led by declines in the
aerospace  and  construction   industries.   Weakness   statewide   occurred  in
manufacturing,  construction,  services,  and trade.  Additional  military  base
closures will have further  adverse  effects on the State's economy later in the
decade.

     Since the start of 1994, the  California  economy has shown signs of steady
recovery and growth.  The State  Department  of Finance  reports net job growth,
particularly in  construction  and related  manufacturing,  wholesale and retail
trade,  transportation,  recreation,  and  services.  This growth has offset the
continuing but slowing job losses in the aerospace industry and restructuring of
the  finance  and  utility   sectors.   Unemployment   in  the  State  was  down
substantially  in 1994 from its 10% peak in  January,  1994,  but still  remains
higher than the  national  average  rate.  Retail sales were up strongly in 1994
from year-earlier  figures.  Delay or slowdown in recovery will adversely affect
State revenues.

CONSTITUTIONAL LIMITATIONS ON TAXES

     Many  California  issuers rely on ad valorem  property taxes as a source of
revenue.  The taxing powers of California  local  governments  and districts are
limited by Article XIIIA of the  California  Constitution,  enacted by voters in
1978 and commonly known as "Proposition  13." Article XIIIA limits to 1% of full
cash value the rate of ad  valorem  taxes on real  property  and  restricts  the
reassessment  of  property  to 2% per year,  except  where new  construction  or
changes of ownership have occurred  (subject to a number of exemptions).  Taxing
entities  may,  however,  raise ad valorem  taxes above the 1% limit to pay debt
service on voter-approved bonded indebtedness. The U.S. Supreme Court has upheld
Proposition 13 against claims that it has unlawfully  resulted in widely varying
tax liability on similarly situated properties.

     Article  XIIIA  also  requires  voters  of any  governmental  unit  to give
two-thirds  approval to levy any  "special  tax."  Subsequent  court  decisions,
however, have allowed non-voter approved "general taxes" so long as they are not
dedicated to a specific use. In response to these  decisions,  voters adopted an
initiative  in 1986 that  imposed new limits on the ability of local  government
entities to raise or levy general  taxes without  voter  approval.  Based upon a
1991  intermediate  appellate court decision,  it was believed that  significant
parts of this initiative,  known as "Proposition 62," were unconstitutional.  On
September 28, 1995, the California Supreme Court rendered a decision in the case
of Santa Clara County Local Transportation  Authority v. Guardino which rejected
the prior  decision and upheld  Proposition  62, while  striking down a 1/2-cent
sales tax for transportation purposes which was approved by a majority, but less
than two-thirds, vote. Proposition 62 does not apply to charter cities,


Statement of Additional Information                                         9


but other local  governments  may be  constrained  in raising any taxes  without
voter approval.

CONSTITUTIONAL LIMITATIONS ON APPROPRIATIONS

     The State and its local governments are subject to an annual appropriations
limit imposed by Article XIIIB of the California Constitution.  This article was
enacted by voters in 1979 and was  significantly  amended by Propositions 98 and
111 in 1988 and  1990,  respectively.  Article  XIIIB  prohibits  the  State and
subject local governments from spending  "appropriations  subject to limitation"
in excess of an  appropriations  limit.  The  appropriations  limit is  adjusted
annually to reflect population changes and changes in the cost of living as well
as transfers of responsibility between government units. "Appropriations subject
to limitation" are authorizations to spend "proceeds of taxes" consisting of tax
revenues  and certain  other  charges and fees to the extent that such  proceeds
exceed the cost of providing the product or service.  However, proceeds of taxes
exclude most State subventions to local governments.

      "Excess  revenues" under Article XIIIB are measured over a two-year cycle.
Local  governments must return any excess revenues to taxpayers through tax rate
reductions.  The State  must  refund  50% of any excess and pay the other 50% to
schools and community  colleges.  With the  application  of more liberal  annual
adjustment  factors  since  1988 and  depressed  revenues  since 1990 due to the
recession,  few governments are currently  operating near their spending limits,
but this  condition  may  change  over time.  Local  governments  may,  by voter
approval, exceed their spending limits for a limited time.

     Because of the complex nature of Articles XIIIA and XIIIB,  the ambiguities
and possible inconsistencies in their terms, and the impossibility of predicting
future appropriations, population changes, changes in the cost of living, or the
probability of continuing legal challenges,  it is difficult to measure the full
impact of these Articles on the California municipal market or on the ability of
California issuers to pay debt service on their obligations.

OBLIGATIONS OF THE STATE OF CALIFORNIA

     As of October 1, 1995, the State had approximately $18.4 billion of general
obligation bonds outstanding, and approximately $3.3 billion remained authorized
but  unissued.  Of the  State's  outstanding  general  obligation  debt,  22% is
presently self-liquidating (i.e., program revenues are expected to be sufficient
to reimburse  the General Fund for debt service  payments).  In fiscal  1994-95,
debt  service  on  general   obligation  bonds  and   lease-purchase   debt  was
approximately 5.25% of General Fund revenues.

     The State's  principal  sources of General Fund revenues for fiscal 1993-94
were the California  personal income tax (44% of total revenues),  the sales tax
(35%),  bank and corporation taxes (12%), and the gross premium tax on insurance
(3%).  Historically,  the State has paid the  principal  of and  interest on its
general obligation bonds,  lease-purchase debt, and short-term  obligations when
due.

     GENERAL.  Throughout  the 1980s,  State spending  increased  rapidly as the
State population and economy also grew rapidly, including increased spending for
many  assistance  programs  to local  governments,  which  were  constrained  by
Proposition  13 and other laws. The largest State program is assistance to local
public school  districts.  In 1988, an initiative  (Proposition  98) was enacted
which  (subject to suspension by a two-thirds  vote of the  Legislature  and the
Governor)  guarantees local school districts and community  college  districts a
minimum share of State General Fund revenues (currently about 33%).

     Since the  start of  1990-91  Fiscal  Year,  the  State  has faced  adverse
economic,  fiscal,  and budget  conditions.  The  economic  recession  seriously
affected State tax revenues.  It also caused  increased  expenditures for health
and welfare  programs.  The State is also facing a  structural  imbalance in its
budget with the largest  programs  supported  by the  General  Fund  (education,
health,  welfare and corrections)  growing at rates higher than the growth rates
for the principal revenue sources of the General Fund. These structural concerns
will be  exacerbated  in  coming  years by the  expected  need to  substantially
increase  capital and operating  funds for  corrections  as a result of a "Three
Strikes" law enacted in 1994.

     RECENT BUDGETS.  As a result of these factors,  among others, from the late
1980s until 1992-93,  the State had a period of nearly chronic budget imbalance,
with  expenditures  exceeding  revenues in four out of six years,  and the State
accumulated  and sustained a budget deficit in the budget  reserve,  the Special
Fund for


10                                               American Century Investments


Economic Uncertainties ("SFEU") approaching $2.8 billion at its peak at June 30,
1993.  Starting in the 1990-91  Fiscal Year and for each year  thereafter,  each
budget  required  multibillion  dollar actions to bring  projected  revenues and
expenditures   into  balance  and  to  close  large  "budget  gaps"  which  were
identified.  The  Legislature  and  Governor  eventually  agreed  on a number of
different  steps  to  produce  Budget  Acts in the  years  1991-92  to  1994-95,
including:

     o  significant cuts in health and welfare program expenditures;

     o  transfers  of program  responsibilities  and  funding  from the State to
        local  governments,  coupled  with some  reduction  in mandates on local
        government;

     o  transfer of about $3.6  billion in annual  local  property  tax revenues
        from cities,  counties,  redevelopment agencies and some other districts
        to local school districts, thereby reducing State funding for schools;

     o  reduction in growth of support for higher education programs, coupled
        with increases in student fees;

     o  revenue increases (particularly in the 1991-92 Fiscal Year budget),
        most of which were for a short duration;

     o  increased  reliance  on aid from the  federal  government  to offset the
        costs of  incarcerating,  educating  and  providing  health and  welfare
        services to  undocumented  aliens  (although these efforts have produced
        much less federal aid than the State Administration has requested); and

     o  various one-time adjustments and accounting changes.

     Despite  these budget  actions,  the effects of the recession led to large,
unanticipated  deficits in the SFEU, as compared to projected positive balances.
By the start of the 1993-94  Fiscal Year, the  accumulated  deficit was so large
(almost  $2.8  billion)  that it was  impractical  to budget to retire it in one
year,  so a two-year  program  was  implemented,  using the  issuance of revenue
anticipation  warrants  to carry a portion  of the  deficit  over the end of the
fiscal  year.  When the economy  failed to recover  sufficiently  in 1993-94,  a
second two-year plan was implemented in 1994-95,  to carry the final  retirement
of the deficit into 1995-96.

     The combination of stringent budget actions cutting State expenditures, and
the  turnaround of the economy by late 1993,  finally led to the  restoration of
positive  financial  results.  While General Fund revenues and expenditures were
essentially equal in FY 1992-93 (following two years of excess expenditures over
revenues),  the General  Fund had positive  operating  results in FY 1993-94 and
1994-95,  which have  reduced  the  accumulated  budget  deficit to around  $600
million as of June 30, 1995.

     A  consequence  of the  accumulated  budget  deficits  in the early  1990s,
together  with  other  factors  such as  disbursement  of funds to local  school
districts  "borrowed" from future fiscal years and hence not shown in the annual
budget, was to significantly  reduce the State's cash resources available to pay
its ongoing obligations. When the Legislature and the Governor failed to adopt a
budget for the 1992-93 Fiscal Year by July 1, 1992, which would have allowed the
State to carry out its normal  annual cash flow  borrowing to replenish its cash
reserves,  the State Controller was forced to issue registered warrants ("IOUs")
to  pay a  variety  of  obligations  representing  prior  years'  or  continuing
appropriations,  and mandates  from court orders.  Available  funds were used to
make  constitutionally-mandated  payments,  such as debt  service  on bonds  and
warrants.  Between July 1, and September 4, 1992, the State Controller  issued a
total of approximately $3.8 billion of registered warrants. After that date, all
remaining  outstanding  registered warrants (about $2.9 billion) were called for
redemption  from proceeds of the issuance of 1992 Interim Notes after the budget
was adopted.

     The State's  cash  condition  became so serious in late spring of 1992 that
the  State  Controller  was  required  to issue  revenue  anticipation  warrants
maturing in the  following  fiscal  year in order to pay the State's  continuing
obligations.  The State was forced to rely increasingly on external debt markets
to meet its cash needs,  as a succession  of notes and  warrants  (both forms of
short-term cash flow financing) were issued in the period from June 1992 to July
1994,  often  needed  to  pay  previously  maturing  notes  or  warrants.  These
borrowings were used also in part to spread out the repayment of the accumulated
budget deficit over the end of a fiscal year.

     The State issued $7.0 billion of  short-term  debt in July 1994 to meet its
cash flow needs and to finance the  deferral of part of the  accumulated  budget
deficit to the 1995-96  fiscal year. In order to assure  repayment of $4 billion
of this borrowing which matures on April 25, 1996, the State enacted legislation
(the  "Trigger  Law")  which  can lead to  automatic,  across-the-board  cuts in
General Fund  expenditures in either the 1994-95 or 1995-96 fiscal years if cash
flow  projections  made at certain  times during those years show  deterioration
from the  projections  made in July  1994  when the  borrowings  were  made.  On
November 15, 1994, the State Controller as part of the Trigger Law reported that
the cash  position of the  General  Fund on June 30,  1995,  would be about $580
million better than earlier  projected,  so no automatic budget adjustments were
required in 1994-95.  The Controller's  report showed that loss of federal funds
was offset by higher revenues,  lower expenditures,  and certain other increases
in cash resources.

     CURRENT  BUDGET.  For the first time in four years,  the State  entered the
1995-96 fiscal year with  strengthening  revenues based on an improving economy.
The major feature of the Governor's  proposed  Budget, a 15% phased tax cut, was
rejected by the Legislature.

     The 1995-96  Budget Act was signed by the  Governor  on August 3, 1995,  34
days after the start of the fiscal year.  The Budget Act  projects  General Fund
revenues and transfers of $44.1 billion,  a 3.5 percent  increase from the prior
year.  Expenditures  are budgeted at $43.4 billion,  a 4 percent  increase.  The
Department of Finance  projects  that,  after repaying the last of the carryover
budget deficit, there will be a positive balance of less than $30 million in the
budget reserve, the Special Fund for Economic  Uncertainties,  at June 30, 1996,
providing no margin for adverse results during the year.

     The  Department  of Finance  projects  cash flow  borrowings in the 1995-96
Fiscal Year will be the smallest in many years,  comprising  about $2 billion of
notes to be issued in April,  1996,  and  maturing by June 30,  1996.  With full
payment of $4 billion of revenue  anticipation  warrants on April 25, 1996,  the
Department  sees no further need for borrowing  over the end of the fiscal year.
The  Department  projects that  available  internal cash  resources to pay State
obligations  will be almost $2 billion at June 30, 1996.  This "cushion" will be
re-examined by the State  Controller on October 15, 1995, in the last step under
the "Trigger Law" process.  If the  Controller  believes the available  internal
cash  resources on June 30, 1996,  will,  in fact,  be zero or less,  her report
would start a process  which  could lead to  automatic  budget cuts  starting in
December 1995.

     The  principal  features  of the  1995-96  Budget Act, in addition to those
noted above,  are additional  cuts in health and welfare  expenditures  (some of
which are subject to  approvals or waivers by the federal  government);  assumed
receipt of an  additional  $473  million of federal  aid for  illegal  immigrant
costs;  and an increase in per-pupil  funding for public  schools and  community
colleges, the first such significant increase in four years.

     In July  1994,  all three of the  rating  agencies  that  rate the  State's
long-term debt lowered their ratings of the State's  general  obligation  bonds.
Moody's Investors Service, Inc. lowered its rating from "Aa" to "A1," Standard &
Poor's  Ratings  Group  lowered  its rating from "A+" to "A" and termed the bond
outlook as "stable," and Fitch Investors  Service,  Inc. lowered its rating from
"AA" to "A." The  credit  quality  of  obligations  issued  by local  California
issuers is not  directly  related to the  quality of  obligations  issued by the
State,  and  the  State  has no  obligation  to  make  payments  on  local  debt
obligations  in the event of default.  As described  below,  the State's  fiscal
problems have placed considerable pressure on local governments.

     Finally,  the State is  involved  in certain  legal  proceedings  that,  if
decided  against the State,  may require  the State to make  significant  future
expenditures or substantially impair revenues.

OBLIGATIONS OF OTHER ISSUERS

     Property tax revenues received by local governments  declined more than 50%
following  passage  of  Proposition  13 in 1978.  Subsequently,  the  California
legislature  enacted measures to provide for the  redistribution  of the State's
General  Fund  surplus to local  agencies,  the  reallocation  of certain  State
revenues to local agencies,  and the assumption of certain government  functions
by the State to assist the State's  municipalities.  However, in response to the
fiscal  crisis at the State  level,  the  Legislature  in  1992-93  and  1993-94
effectively  reversed the post-Proposition 13 "bailout" aid and directed over $3
billion  of  city,  county,  and  special  district  property  taxes  to  school
districts, which


12                                                AmericanCentury Investments


enabled the State to reduce its aid to schools by the same amount.  Part of this
shortfall  is to be covered by a 0.5% sales tax  allocated  to local  government
public safety  purposes.  The 0.5% sales tax increase was imposed by Proposition
172,  which was  approved by a majority of voters at the  statewide  election on
November 2, 1993.

     Even with these cuts and property tax shifts, over 70% of the State General
Fund  expenditures are for local government  assistance.  To the extent that the
State is constrained by its Article XIIIB  appropriations  limit, its obligation
to conform to Proposition 98, or other fiscal considerations, the absolute level
or rate of growth of State assistance to local  governments may be reduced.  Any
such  reductions  in State aid could  compound  the serious  fiscal  constraints
already experienced by many local governments, particularly counties.

INVESTMENT RESTRICTIONS

     The Funds'  investment  restrictions are set forth below.  These investment
restrictions  are  fundamental  and may not be changed  without  approval  of "a
majority of the outstanding  votes of  shareholders" of a Fund, as determined in
accordance with the  Invest-ment  Company Act of 1940 (the  "Investment  Company
Act").

     AS A FUNDAMENTAL POLICY, EACH FUND SHALL NOT:

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

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

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

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

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

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

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

8)   invest for purposes of exercising control over management.

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

     AS AN OPERATING POLICY, EACH FUND:

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


Statement of Additional Information                                         13


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

c)   [Money  Market Funds only] shall not purchase or sell futures  contracts or
     call options.  This  limitation  does not apply to options  attached to, or
     acquired or traded together with, their underlying securities, and does not
     apply to securities that incorporate features similar to options or futures
     contracts.

d)   shall not purchase any security or enter into a repurchase agreement if, as
     a result,  more than 15% of its net assets (10% for the 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.

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

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

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

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

     For purposes of the Funds' investment restrictions, the party identified as
the "issuer" of a municipal  security  depends on the form and conditions of the
security.  When the assets and revenues of a political  subdivision are separate
from those of the government  that created the  subdivision  and the security is
backed only by the assets and revenues of the  subdivision,  the  subdivision is
deemed  the sole  issuer.  Similarly,  in the case of an IDB,  if the bond  were
backed  only  by  the  assets  and  revenues  of a  non-governmental  user,  the
non-governmental  user would be deemed the sole issuer.  If, in either case, the
creating  government or some other entity were to guarantee  the  security,  the
guarantee would be considered a separate security and treated as an issue of the
guaranteeing entity.

PORTFOLIO TRANSACTIONS

     Each Fund's assets are invested by the Manager in a manner  consistent with
the Fund's  investment  objectives,  policies,  and  restrictions,  and with any
instructions  the Board of  Trustees  may issue from time to time.  Within  this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement securities transactions on behalf of the Funds.

     In placing  orders for the purchase and sale of portfolio  securities,  the
Manager  will  use its best  efforts  to  obtain  the best  possible  price  and
execution and will otherwise place orders with broker-dealers  subject to and in
accordance  with any  instructions  the Board of Trustees may issue from time to
time. The Manager will select broker-dealers to execute portfolio transac-


14                                                American Century Investments


tions on behalf of the Funds solely on the basis of best price and execution.

     Under  normal  conditions,   the  Variable-Price  Funds'  annual  portfolio
turnover rates are not expected to exceed 100%.  Because a higher  turnover rate
increases  transaction costs and may increase taxable capital gains, the Manager
carefully weighs the potential  benefits of short-term  investing  against these
considerations.

     The  Variable-Price  Funds'  portfolio  turnover rates for the fiscal years
ended August 31, 1996, and 1995, are indicated in the table below.

                          Portfolio Turnover Rates

- ---------------------------------------------------------------------------
California Limited-Term Tax-Free                43.70%            49.75%
California Intermediate-Term Tax-Free           35.66%            25.44%
California Long-Term Tax-Free                   41.66%            59.92%
California High-Yield Municipal                 35.98%            40.00%
California Insured Tax-Free                     42.71%            40.45%
- ------------------------------------------------------------------------

     Investment  decisions are made for each Fund  independently from those made
for other funds advised by the Manager.  From time to time, however, two or more
funds advised by the Manager may hold the same security.  When two or more funds
are simultaneously  engaged in purchasing or selling a security,  the prices and
amounts are  allocated  in a manner  believed by the Manager to be  equitable to
each of the funds involved. In some instances,  simultaneous  transactions could
have a  detrimental  effect  on the price or value of a  security  as far as the
participating funds are concerned.  In other instances,  however, the ability to
participate in volume transactions will produce better prices and executions for
the funds.

VALUATION OF PORTFOLIO SECURITIES

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

     The  Manager  typically  completes  its  trading  on behalf of each Fund in
various  markets before the Exchange closes for the day. Each Fund's share price
is calculated by adding the value of all portfolio  securities and other assets,
deducting  liabilities,  and  dividing  the  result  by  the  number  of  shares
outstanding.  Expenses and interest  earned on portfolio  securities are accrued
daily.

     MONEY MARKET FUNDS. Securities held by the Money Market Funds are valued at
amortized  cost.  This method  involves  valuing an  instrument  at its cost and
thereafter  assuming a constant  amortization  to  maturity  of any  discount or
premium paid at the time of purchase. Although this method provides certainty in
valuation,  it generally  disregards the effect of fluctuating interest rates on
an instrument's  market value.  Consequently,  the  instrument's  amortized cost
value may be higher or lower than its market value,  and this discrepancy may be
reflected in the Funds' yields.  During periods of declining interest rates, for
example,  the daily yield on Fund  shares  computed  as  described  above may be
higher than that of a fund with  identical  investments  priced at market value.
The converse would apply in a period of rising interest rates.

     The Money  Market Funds  operate  pursuant to  Investment  Company Act Rule
2a-7, which permits valuation of portfolio  securities on the basis of amortized
cost.  As required by the Rule,  the Board of  Trustees  has adopted  procedures
designed to stabilize,  to the extent reasonably possible, a Money Market Fund's
price per share as computed for the purposes of sales and  redemptions at $1.00.
While the  day-to-day  operation of the Money Market Funds has been delegated to
the  Manager,  the quality  requirements  established  by the  procedures  limit
investments  to certain  instruments  that the Board of Trustees has  determined
present  minimal credit risks and that 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 unrated securities,  of comparable quality.  The
procedures  require review of the Money Market Fund's portfolio holdings at such
intervals as are reasonable in light of current market conditions to determine


Statement of Additional Information                                        15


whether the Money Market 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.

     The Board of Trustees monitors the levels of illiquid  securities,  however
if the levels are exceeded, they will take action to rectify these levels.

     Actions  the Board of  Trustees  may  consider  under  these  circumstances
include (i) selling  portfolio  securities  prior to maturity,  (ii) withholding
dividends or distributions  from capital,  (iii) authorizing a one-time dividend
adjustment, (iv) discounting share purchases and initiating redemptions in kind,
or (v) valuing portfolio  securities at market price for purposes of calculating
NAV.

     VARIABLE-PRICE FUNDS.  Securities held by the Variable-Price Funds normally
are priced by an  independent  pricing  service,  provided  that such prices are
believed  by  the  Manager  to  reflect  the  fair  market  value  of  portfolio
securities.

     Because  there are hundreds of thousands of municipal  issues  outstanding,
and the  majority  of them do not trade  daily,  the prices  provided by pricing
services are generally  determined without regard to bid or last sale prices. In
valuing   securities,   the  pricing   services   generally  take  into  account
institutional trading activity, trading in similar groups of securities, and any
developments  related to specific  securities.  The methods  used by the pricing
service and the valuations so established  are reviewed by the Manager under the
general  supervision  of the Board of  Trustees.  There are a number of  pricing
services available, and the Manager, on the basis of ongoing evaluation of these
services,  may use other pricing  services or discontinue the use of any pricing
service in whole or in part.

     Securities  not priced by a pricing  service are valued at the mean between
the most  recently  quoted bid and ask prices  provided by  broker-dealers.  The
municipal bond market is typically a "dealer  market";  that is, dealers buy and
sell bonds for their own accounts  rather than for customers.  As a result,  the
spread, or difference  between bid and asked prices, for certain municipal bonds
may differ substantially among dealers.

     Securities  maturing  within 60 days of the valuation date may be valued at
cost,  plus or minus any  amortized  discount  or premium,  unless the  Trustees
determine  that this would not  result in fair  valuation  of a given  security.
Other assets and securities for which  quotations are not readily  available are
valued in good faith at their fair value using methods  approved by the Board of
Trustees.

PERFORMANCE

     The Funds may quote  performance  in various ways.  Historical  performance
information will be used in advertising and sales literature.

     For the Money Market Funds, yield quotations are based on the change in the
value of a hypothetical investment (excluding realized gains and losses from the
sale of securities and unrealized  appreciation  and depreciation of securities)
over a  seven-day  period  (base  period)  and  stated  as a  percentage  of the
investment at the start of the base period (base-period return). The base-period
return is then  annualized  by  multiplying  by 365/7 with the  resulting  yield
figure carried to at least the nearest hundredth of one percent.

     Calculations of effective yield begin with the same base-period return used
to  calculate  yield,  but the  return  is then  annualized  to  reflect  weekly
compounding according to the following formula:

Effective Yield = [(Base-Period Return + 1)365/7] - 1

     The Money  Market  Funds'  yields and  effective  yields for the  seven-day
period ended August 31, 1996, were as follows:

Money Market Fund                         7-Day Yield      Effective Yield
- --------------------------------------------------------------------------
California Tax-Free Money Market             2.85%              2.89%
California Municipal Money Market            2.96%              3.01%
- --------------------------------------------------------------------------

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

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

where a = dividends and interest earned during the


16                                                American Century Investments


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

     The  Variable-Price  Funds'  yields for the 30-day  period ended August 31,
1996, were as follows:

Variable-Price Fund                                     30-Day Yield
- -----------------------------------------------------------------------
California Limited-Term Tax-Free                            3.72%
California Intermediate-Term Tax-Free                       4.43%
California Long-Term Tax-Free                               5.03%
California High-Yield Municipal                             5.63%
California Insured Tax-Free                                 4.88%
- -----------------------------------------------------------------------

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

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

     The Funds'  average annual total returns for the one-year,  five-year,  and
ten-year or  life-of-fund  periods  ended August 31, 1996,  are indicated in the
table below.

     In addition to average annual total returns, each Fund may quote unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment over a stated period. Average annual and cumulative total returns may
be quoted as percentages or as dollar amounts and may be calculated for a single
investment,  a series of investments,  or a series of redemptions  over any time
period.  Total  returns may be broken down into their  components  of income and
capital  (including  capital gains and changes in share price) to illustrate the
relationship of these factors and their contributions to total return.

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

illustrate historical performances.

TAXES

FEDERAL INCOME TAX

     Each Fund intends to qualify annually as a "regulated  investment  company"
under  Subchapter  M of the  Internal  Revenue  Code of 1986,  as  amended  (the
"Code").  By so  qualifying,  a Fund will be exempt from federal and  California
income  taxes to the extent  that it  distributes  substantially  all of its net
investment income and net realized capital gains (if any) to shareholders.

     Certain  of the bonds  purchased  by the Funds may be treated as bonds that
were  originally  issued  at a  discount.  Original  issue  discount  represents
interest for federal  income tax  purposes  and can  generally be defined as the
difference  between  the price at which a  security  was  issued  and its stated
redemption  price at  maturity.  Original  issue  discount,  although no cash is
actually  received  by a Fund until the  maturity  of the bond,  is treated  for
federal  income  tax  purposes  as income  earned by a Fund over the term of the
bond, and therefore is subject to the distribution requirements of the Code. The
annual amount of income earned on such a bond by a Fund  generally is determined
on the basis of a  constant  yield to  maturity  that  takes  into  account  the
semiannual  compounding  of accrued  interest.  Original  issue  discount  on an
obligation  with  interest  exempt  from  federal  income  tax  will  constitute
tax-exempt interest income to the Fund.

     In  addition,  some of the bonds may be  purchased  by a Fund at a discount
that exceeds the original issue discount on such bonds,  if any. This additional
discount  represents  market discount for federal income tax purposes.  The gain
realized on the disposition of any bond having market discount generally will be
treated as taxable  ordinary income to the extent it does not exceed the accrued
market discount on such bond (unless a Fund elects to include market discount in
income in tax years to which it is  attributable).  Generally,  market  discount
accrues  on a daily  basis for each day the bond is held by a Fund on a straight
line basis over the time  remaining to the bond's  maturity.  In the case of any
debt security  having a fixed  maturity date of not more than one year from date
of  issue,  the gain  realized  on  disposition  generally  will be  treated  as
short-term capital gain. In general,  gain realized on disposition of a security
held less than one year is treated as short-term capital gain.

     It is intended  that each Fund's  assets will be  sufficiently  invested in
municipal  securities so that each Fund will be eligible to pay "exempt-interest
dividends" (as defined in the Code) to shareholders.  A Fund's dividends payable
from net tax-exempt interest earned from municipal securities will qualify to be
designated as exempt-interest  dividends if, at the close of each quarter of the
Fund's  taxable  year,  at least 50% of the  value of the  Fund's  total  assets
consists of  municipal  securities.  Exempt-interest  dividends  distributed  to
shareholders are not included in shareholders'  gross income for regular federal
income tax  purposes.  The  percentage  of income that is  tax-exempt is applied
uniformly to all  distributions  made during each calendar year. This percentage
may differ from the actual  percentage of tax-exempt  income received during any
particular month.

     Distributions  of net investment  income received by a Fund from investment
in debt securities other than municipal securities,  of ordinary income realized
upon the disposition of tax-exempt market discount bonds,


18                                               American Century Investments


and any net realized  short-term  capital gains  distributed by the Fund will be
taxable to shareholders as ordinary income. Because the Funds' investment income
is derived from interest rather than dividends, no portion of such distributions
is eligible for the dividends-received deduction available to corporations.

     Under the Code, any distribution of a Fund's net realized long-term capital
gains  designated  by  the  Fund  as a  capital  gain  dividend  is  taxable  to
shareholders as long-term capital gains, regardless of the length of time shares
are held.  If a capital  gain  dividend is paid with  respect to any shares of a
Fund sold at a loss after  being  held for six months or less,  the loss will be
treated as a long-term  capital loss for tax  purposes.  The Code also  provides
that if a  shareholder  holds  shares  of a Fund for six  months  or  less,  the
deduction of any loss on the sale or exchange of those shares is  disallowed  to
the extent that the shareholder received exempt-interest  dividends with respect
to those shares.

     As of August 31, 1996, the Funds had the following  capital loss carryovers
of $298,508 for  California  Tax-Free  Money  Market,  $158,606  for  California
Municipal  Money  Market,  $359,444 for  California  High-Yield  Municipal,  and
$654,341 for California  Insured  Tax-Free  (expiring 1998 through 2004).  As of
August 31, 1996,  California  Limited-Term Tax-Free had a capital loss carryover
of  $1,151,341  (expiring  2003  and  2004).  When a  Fund  has a  capital  loss
carryover,  it does not make capital gain distributions  until the loss has been
offset or expired.

     Interest on certain types of industrial development bonds (small issues and
obligations issued to finance certain exempt facilities that may be leased to or
used by persons  other than the  issuer) is not exempt from  federal  income tax
when received by "substantial  users" or persons related to substantial users as
defined  in the Code.  The term  "substantial  user"  includes  any  "non-exempt
person" who regularly uses in trade or business part of a facility financed from
the proceeds of industrial  development bonds. The Funds may invest periodically
in  industrial  development  bonds  and,  therefore,   may  not  be  appropriate
investments  for entities that are substantial  users of facilities  financed by
industrial   development  bonds  or  "related  persons"  of  substantial  users.
Generally,  an individual  will not be a related  person of a  substantial  user
under the Code unless he or his immediate  family  (spouse,  brothers,  sisters,
ancestors and lineal  descendants) owns directly or indirectly in aggregate more
than 50% in the equity value of the substantial user.

     From time to time,  proposals  have been  introduced  in  Congress  for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal securities, and similar proposals may be introduced in the
future.  If  such  a  proposal  were  enacted,  the  availability  of  municipal
securities  for  investment  by the Funds and the Funds' NAVs would be adversely
affected.  Under these circumstances,  the Trustees would re-evaluate the Funds'
investment  objectives  and policies and would  consider  either  changes in the
structure of the Trust or its dissolution.

ALTERNATIVE MINIMUM TAX

     While the  interest on bonds  issued to finance  essential  state and local
government  operations  is  generally  exempt from regular  federal  income tax,
interest on certain "private  activity" bonds issued after August 7, 1986, while
exempt from regular federal income tax,  constitutes a  tax-preference  item for
taxpayers in determining  alternative  minimum tax liability  under the Code and
income tax provisions of several states.

     California  Municipal Money Market and California  High-Yield Municipal may
each invest in private  activity bonds.  The interest on private  activity bonds
could  subject a  shareholder  to, or  increase  liability  under,  the  federal
alternative  minimum tax,  depending on the  shareholder's  tax  situation.  The
interest  on  California  private  activity  securities  is not  subject  to the
California alternative minimum tax when it is earned (either directly or through
investment in a mutual fund) by a California  taxpayer.  However, if either Fund
were to invest in private activity securities of non-California  issuers (due to
a limited supply of appropriate California municipal obligations,  for example),
the interest on those  securities  would be included in  California  alternative
minimum taxable income.

     All distributions  derived from interest exempt from regular federal income
tax may subject  corporate  shareholders  to, or increase their liability under,
the  alternative  minimum tax because  these  distributions  are included in the
corporation's "adjusted current earnings."

     In  addition,  a  deductible  "environmental  tax" of 0.12% is imposed on a
corporation's  modified  alternative  minimum  taxable  income  in  excess of $2
million.


Statement of Additional Information                                        19


The environmental tax will be imposed even if the corporation is not required to
pay an  alternative  minimum tax. To the extent that  exempt-interest  dividends
paid by a Fund are included in alternative  minimum  taxable  income,  corporate
shareholders may be subject to the environmental tax.

     The Trust will inform  California  Municipal  Money  Market and  California
High-Yield  Municipal  shareholders  annually  of the  amount  of  distributions
derived from interest payments on private activity bonds.

STATE AND LOCAL TAXES

     California  law  concerning  the payment of  exempt-interest  dividends  is
similar to federal law.  Assuming  each Fund  qualifies  to pay  exempt-interest
dividends under federal and California law, and to the extent that dividends are
derived  from  interest  on  tax-exempt  bonds  of  California  state  or  local
governments,  such dividends will also be exempt from California personal income
tax.  The  Trust  will  inform  shareholders   annually  as  to  the  amount  of
distributions  from each  Fund that  constitute  exempt-interest  dividends  and
dividends  exempt from California  personal income tax. The Funds' dividends are
not exempt from California state franchise or corporate income taxes.

     The Funds'  dividends may not qualify for  exemption  under income or other
tax laws of state or local taxing authorities outside  California.  Shareholders
should  consult their tax advisors or state or local tax  authorities  about the
status of distributions from the Funds in this regard.

     The information  above is only a summary of some of the tax  considerations
affecting the Funds and their shareholders.  No attempt has been made to discuss
individual tax consequences.  A prospective  investor should consult with his or
her tax  advisors or state or local tax  authorities  to  determine  whether the
Funds are suitable investments.

ABOUT THE TRUST

     American Century California Tax-Free and Municipal Funds (the "Trust") is a
registered  open-end  management  investment  company  that was  organized  as a
Massachusetts  business trust on February 18, 1983.  American Century California
Tax-Free  and  Municipal  Funds was known as  "Benham  California  Tax-Free  and
Municipal Funds" until January 1997.

     Currently, there are seven series (or Funds) of the Trust. The table on the
following page lists each Fund's current and prior name.

     Prior to  September  1996,  California  Limited-Term  Tax-Free was known as
"Benham California  Tax-Free  Short-Term Fund." The Board of Trustees may create
additional series from time to time.

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

     Each series votes separately on matters affecting that series  exclusively.
Voting rights are not cumulative, so that investors holding more than 50% of the
Trust's (i.e., all series')  outstanding  shares may be able to elect a Board of
Trustees. The Trust has instituted  dollar-based voting, meaning that the number
of votes you are entitled to is based upon the dollar amount of your investment.
The  election of Trustees is  determined  by the votes  received  from all Trust
shareholders  without  regard to whether a majority  of shares of any one series
voted in favor of a particular nominee or all nominees as a group.

     Each  shareholder  has rights to dividends  and  distributions  declared by
their  series  and to the net  assets of such  series  upon its  liquidation  or
dissolution  proportionate to his or her share ownership interest in the series.
Shares of each series  have equal  voting  rights,  although  each series  votes
separately on matters affecting that series exclusively.

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


20                                                American Century Investments


liabilities.  Thus,  the risk of a  shareholder  incurring  financial  loss as a
result of  shareholder  liability  is  limited  to  circumstances  in which both
inadequate insurance exists and the Trust is unable to meet its obligations.

     CUSTODIAN BANKS: Chase Manhattan Bank, 4 Chase Metrotech Center,  Brooklyn,
New York 11245 and  Commerce  Bank,  N. A., 1000 Walnut,  Kansas City,  Missouri
64106,  serve as  custodians  of the Funds'  assets.  Services  provided  by the
custodian  bank  include  (i)  settling  portfolio  purchases  and  sales,  (ii)
reporting failed trades,  (iii) identifying and collecting portfolio income, and
(iv)  providing  safekeeping  of  securities.  The  custodians  take  no part in
determining the Funds'  investment  policies or in determining  which securities
are sold or purchased by the Funds.

     INDEPENDENT  AUDITORS:  KPMG Peat  Marwick LLP,  1000  Walnut,  Suite 1600,
Kansas City,  Missouri  64106,  serves as the Trust's  independent  auditors and
provides services including the audit of the annual financial statements.

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

compensation  received  for  serving as a Director or Trustee of all other funds
advised by the Manager.

     As of November 30, 1996,  the Funds'  Trustees  and  officers,  as a group,
owned  less than 1% of each  Fund's  total  shares  outstanding,  except for the
California  Tax-Free  Money  Market of which they owned as a group  0.95% of the
Fund's shares outstanding.

MANAGEMENT

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

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

     The schedules by which the  Investment  Category Fee are  determined are as
follows:

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

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

     The management  agreement shall continue in effect until the earlier of the
expiration  of two  years  from the date of its  execution  or until  the  first
meeting of  shareholders  following such execution and for as long thereafter as
its  continuance  is  specifically  approved at least annually by (1) the Funds'
Board of Trustees, or by the vote of a majority of outstanding votes (as defined
in the Investment Company Act) and (2) by the vote of a majority of the Trustees
of the 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 Trustees,  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,
trustees and employees may engage in other  business,  devote time and attention
to any other  business  whether of a similar or  dissimilar  nature,  and render
services to others.

     Certain  investments  may be  appropriate  for the 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 invest-


24                                                American Century Investments


ment 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 other  clients when the Manager  believes  that
such aggregation  provides the best execution for the Funds. The Funds' Board of
Trustees has approved the policy of the Manager with respect to the  aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the 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,  the Manager also acts as an  investment
advisor to 12 institutional  accounts and to the following registered investment
companies:  American Century Mutual Funds,  Inc.,  American Century World Mutual
Funds, Inc., American Century Premium Reserves,  Inc., American Century Variable
Portfolios,  Inc., American Century Capital  Portfolios,  Inc., American Century
Strategic Asset Allocations,  Inc.,  American Century Municipal Trust,  American
Century  Government Income Trust,  American Century  Investment Trust,  American
Century Target Maturities Trust,  American Century Quantitative Equity Funds and
American Century International Bond Funds.

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

     Investment  advisory  fees paid by each Fund for the fiscal  periods  ended
August 31, 1996,  1995,  and 1994,  are  indicated in the following  table.  Fee
amounts  are net of amounts  reimbursed  or recouped  under the Funds'  previous
investment advisory agreement with Benham Management Corporation.

It provides physical  facilities,  including  computer hardware and software and

MUNICIPAL SECURITIES RATINGS

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

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

     Aaa: Bonds that are rated "Aaa" are judged to be of the best quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
"gilt edge." Interest payments are protected by a large or exceptionally  stable
margin,  and  principal  is secure.  While the various  protective  elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

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

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

     Baa:  Bonds that are rated "Baa" are considered  medium-grade  obligations,
i.e., they are neither highly  protected nor poorly secured.  Interest  payments
and principal security appear adequate for the present, but


Statement of Additional Information                                        27


certain  protective  elements  may  be  lacking  or  may  be  characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and, in fact, have speculative characteristics as well.

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

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

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

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

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

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

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

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

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

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

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

     Moody's  commercial paper ratings are opinions of the ability of issuers to
punctually repay those promissory obligations that have an original maturity not
exceeding nine months. Moody's makes no representation that such obligations are
exempt from registration under the Securities Act of 1933, nor does it represent
that any  specific  note is a valid  obligation  of a rated  issuer or issued in
conformity with any applicable law. The following designations, all judged to be
investment  grade,  indicate the relative  repayment ability of rated issuers of
securities in which the Funds may invest.

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

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

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

INVESTMENT GRADE

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

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

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

     BBB:  Debt rated "BBB" is  regarded  as having an adequate  capacity to pay
interest and repay principal.  Whereas it normally exhibits adequate  protection
para-


28                                               American Century Investments


meters, adverse economic conditions or changing circumstances are more likely to
lead to a weakened capacity to pay interest and repay principal for debt in this
category than in higher-rated categories.

SPECULATIVE

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

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

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

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

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

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

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

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

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

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

     SP-1:  Issues  carrying  this  designation  have a very  strong  or  strong
capacity to pay  principal  and  interest.  Those issues  determined  to possess
overwhelming safety characteristics will be given a plus (+) designation.

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

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

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

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

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

DESCRIPTION OF FITCH INVESTORS SERVICE, INC.'S RATINGS
FOR MUNICIPAL BONDS:

INVESTMENT GRADE

     AAA:  Bonds  considered  to be investment  grade and of the highest  credit
quality.  The obligor has an  exceptionally  strong  ability to pay interest and
repay  principal  that is  unlikely to be  affected  by  reasonably  foreseeable
events.

     AA:  Bonds  considered  to be  investment  grade  and of very  high  credit
quality.  The  obligor's  ability to pay  interest  and repay  principal is very
strong, although not quite


Statement of Additional Information                                        29


as  strong  as bonds  rated  "AAA."  Because  bonds  rated in the "AAA" and "AA"
categories are not significantly  vulnerable to foreseeable future developments,
short-term debt of these issuers is generally rated "F-1+."

     A: Bonds considered to be investment grade and of high credit quality.  The
obligor's  ability to pay  interest  and repay  principal  is  considered  to be
strong, but may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

     BBB: Bonds  considered to be investment  grade and of  satisfactory  credit
quality. The obligor's ability to pay interest and repay principal is considered
to be  adequate.  Adverse  changes in  economic  conditions  and  circumstances,
however,  are more likely to have  adverse  impact on these bonds and  therefore
impair timely payment.  The likelihood that the ratings of these bonds will fall
below investment grade is higher than for bonds with higher ratings.

     PLUS (+) MINUS (-):  Plus and minus signs are used with a rating  symbol to
indicate the relative position of a credit within the rating category.  Plus and
minus signs, however, are not used in the "AAA" category.

SPECULATIVE

     BB: Bonds are considered speculative. The obligor's ability to pay interest
and repay  principal  may be  affected  over time by adverse  economic  changes.
However, business and financial alternatives can be identified that could assist
the obligor in satisfying its debt service requirements.

     B: Bonds are considered highly  speculative.  While bonds in this class are
currently meeting debt service requirements, the probability of continued timely
payment of principal  and  interest  reflects the  obligor's  limited  margin or
safety and the need for reasonable business and economic activity throughout the
life of the issue.

     CCC: Bonds have certain identifiable characteristics that, if not remedied,
may lead to default.  The ability to meet  obligations  requires an advantageous
business and economic environment.

     CC: Bonds are minimally  protected.  Default in payment of interest  and/or
principal seems probable over time.

     C: Bonds are in imminent default in payment of interest or principal.

     DDD/DD/D:  Bonds are in default on interest and/or principal payments. Such
bonds  are  extremely  speculative  and  should  be valued on the basis of their
ultimate recovery value in liquidation or  reorganization of the obligor.  "DDD"
represents the highest potential for recovery on these bonds, and "D" represents
the lowest potential for recovery.

     Plus (+) Minus (-):  Plus and minus signs are used with a rating  symbol to
indicate the relative position of a credit within the rating category.  Plus and
minus signs, however, are not used in the "DDD," "DD," or "D" categories.

DESCRIPTION OF FITCH INVESTORS SERVICE, INC.'S RATINGS FOR
INVESTMENT-GRADE MUNICIPAL NOTES AND SHORT-TERM
DEMAND OBLIGATIONS:

     F-1+:  Exceptionally Strong Credit Quality. Issues assigned this rating are
regarded as having the strongest degree of assurance for timely payment.

     F-1: Very Strong Credit  Quality.  Issues  assigned this rating  reflect an
assurance  of timely  payment  only  slightly  less in degree than issues  rated
"F-1+."

QUALITY OF PORTFOLIO SECURITIES HELD BY THE VARIABLE PRICE
FUNDS

     The table below provides a summary of ratings  assigned to obligations held
by each of the Variable Price Funds. These figures are dollar-weighted  averages
of month-end  holdings  during  fiscal 1996,  presented as a percentage of total
investments. For obligations with different ratings assigned by different rating
agencies,  the  highest  rating  assigned  is the one relied upon to create this
table.  The  percentages  are historical and are not  necessarily  indicative of
current or future portfolio holdings, which may vary in quality.

                               Prime Money Market
                         SUPPLEMENT DATED JULY 31, 1997
                          Prospectus dated July 1, 1997

SPECIAL MEETING OF SHAREHOLDERS

At a Special Meeting of Shareholders held on July 30, 1997,  shareholders of the
Fund approved,  among other things, a new Management  Agreement between the Fund
with American Century Investment Management,  Inc. This new Management Agreement
will  become  effective  on August 1, 1997,  and  replaces  the  Fund's  current
investment advisory agreement with Benham Management  Corporation,  an affiliate
of American Century Investment Management, Inc. At the meeting,  shareholders of
the Fund also ratified the selection of Coopers & Lybrand LLP as the independent
auditors  for the Fund's  current  fiscal  year and  approved  the  adoption  of
standardized  investment  limitations by amending or eliminating  certain of the
Fund's  fundamental  investment  limitations.  The  changes  resulting  from the
Special Meeting of Shareholders are reflected in this Prospectus  Supplement and
in the revised Statement of Additional Information of the Fund.

     The shares offered by this Prospectus are Investor Class shares and have no
up-front or deferred  sales  charges,  commissions,  or 12b-1 fees. The Investor
Class is currently the only class of shares offered by the Fund.

INVESTMENT MANAGEMENT

On page 19, the first two paragraphs in the subsection  "Investment  Management"
are deleted and replaced with the following:

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

On page 20, the four paragraphs appearing before the subsection heading "Code of
Ethics" are deleted and replaced with the following:

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

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

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

TRANSFER AND ADMINISTRATIVE SERVICES

On page 20, the first paragraph under the heading  "Transfer and  Administrative
Services" is deleted and replaced with the following:

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

EXPENSES

On page 21, the subsection called "Expenses" is deleted.

INVESTMENT POLICIES AND TECHNIQUES

The following  paragraphs provide a more detailed  description of the securities
and investment practices  identified in the Prospectus.  Unless otherwise noted,
the policies  described  in this  Statement of  Additional  Information  are not
fundamental and may be changed by the board of trustees.

COMMERCIAL PAPER

Commercial  paper  ("CP")  is  issued  by  utility,  financial,  and  industrial
companies and supranational  organizations.  Nationally  recognized  statistical
rating organizations ("rating agencies") assign ratings to CP issuers indicating
the agencies' assessment of credit risk. Investment grade CP ratings assigned by
four rating agencies are provided in the following table.
<TABLE>

                        Moody's         Standard                              Fitch

                        Prime-3            A-3               D-3               F-3
- ---------------------------------------------------------------------------------------------
</TABLE>

If an  obligation  has  been  assigned  different  ratings  by  multiple  rating
agencies,  at least two rating  agencies must have assigned their highest rating
as indicated  above in order for the Manager to determine that the obligation is
eligible  for  purchase  by the Fund or,  if  unrated,  the  obligation  must be
determined to be of comparable quality by the Manager.

Some examples of CP and CP issuers are provided in the following paragraphs.

Domestic  CP is  issued  by  U.S.  industrial  and  finance  companies,  utility
companies, thrifts, and bank holding companies. Foreign CP is issued by non-U.S.
industrial  and finance  companies  and  financial  institutions.  Domestic  and
foreign  corporate  issuers  occasionally  have  the  underlying  support  of  a
well-known,  highly rated commercial bank or insurance company.  Bank support is
provided  in the form of a letter of credit (a "LOC") or  irrevocable  revolving
credit  commitment  (an "IRC").  Insurance  support is provided in the form of a
surety bond.

Bank Holding  Company CP is issued by the holding  companies of many  well-known
domestic banks,  including  Citicorp,  J.P. Morgan & Company  Incorporated,  and
First Union National Bank.  Bank holding  company CP may be issued by the parent
of a money center or regional bank.

Thrift  CP is  issued  by major  federal  or  state-chartered  savings  and loan
associations and savings banks.

Schedule B Bank CP is short-term,  U.S. dollar-denominated CP issued by Canadian
subsidiaries  of  non-Canadian  banks  (Schedule  B  banks).  Whether  issued as
commercial  paper,  a  certificate  of  deposit,  or  a  promissory  note,  each
instrument  issued by a  Schedule B bank ranks  equally  with any other  deposit
obligation.  Paper  issued by Schedule B banks  provides  an  investor  with the
comfort  and  reduced  risk of a direct and  unconditional  parental  guarantee.
Schedule  B  instruments  generally  offer  higher  rates  than  the  short-term
instruments of the parent bank or holding company.

REPURCHASE AGREEMENTS

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

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

2                                                   American Century Investments

of those which have been approved by the Board as sufficiently creditworthy.

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

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

REVERSE REPURCHASE AGREEMENTS

In a reverse repurchase  agreement,  the Fund transfers possession of (or sells)
securities  to  another  party,  such as a bank or  broker-dealer,  for cash and
agrees to later repay cash plus interest for the return (or  repurchase)  of the
same securities.  To collateralize the transaction,  the value of the securities
transferred  is slightly  greater  than the amount of cash the Fund  receives in
exchange for the securities.

If the purchaser  reneged on the agreement and failed to return the  securities,
the Fund  might  suffer a loss.  The Fund's  loss  could be even  greater if the
market value of the securities transferred increased in the meantime. To protect
against these risks, the Fund will enter into reverse repurchase agreements only
with parties whose  creditworthiness  is determined  to be  satisfactory  by the
Manager.  While a reverse  repurchase  agreement is  outstanding,  the Fund will
maintain sufficient liquid assets in a segregated custodial account to cover its
obligation under the agreement.

TAXABLE MUNICIPAL OBLIGATIONS

Taxable  municipal  obligations are state and local  obligations  whose interest
payments   are  subject  to  federal   income  tax  because  of  the  degree  of
non-government  involvement  in the  transaction  or  because  federal  tax code
limitations on the issuance of tax-exempt  bonds that benefit  private  entities
have been  exceeded.  Some  typical  examples of taxable  municipal  obligations
include industrial revenue bonds and economic  development bonds issued by state
or local  governments  to aid  private  enterprise.  The  interest  on a taxable
municipal  bond is often exempt from state  taxation in the issuing  state.  The
Fund may purchase taxable municipal  obligations  although it does not currently
intend to do so.

TIME DEPOSITS

Time deposits are non-negotiable  bank deposits  maintained for up to seven days
at a stated  interest  rate.  These  instruments  may be  withdrawn  on  demand,
although early withdrawals may be subject to penalties.

WHEN-ISSUED SECURITIES, FORWARD COMMITMENT
AGREEMENTS AND ROLL TRANSACTIONS

The Fund may  engage in  securities  transactions  on a  when-issued  or forward
commitment basis, in which the transaction price and yield are each fixed at the
time the  commitment  is made,  but payment and delivery  occur at a future date
(typically 1 to 7 days later).

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

In purchasing  securities on a when-issued or forward commitment basis, the Fund
will  establish  and maintain  until the  settlement  date a segregated  account
consisting of cash or appropriate  liquid  securities in an amount sufficient to
meet  the  purchase  price.  When  the  time  comes  to pay for the  when-issued
securities,  the Fund will meet its obligations with available cash, through the
sale of  securities,  or,  although  it would not  normally  expect to do so, by
selling the  when-issued  securities  themselves  (which may have a market value
greater or less than the Fund's payment obligation).  Selling securities to meet
when-issued or forward commitment obligations may generate taxable capital gains
or losses.

The Fund may sell a security and at the same time make a commitment  to purchase
the  same or a  comparable  security  at a  future  date  and  specified  price.
Conversely,  the Fund may  purchase  a  security  and at the  same  time  make a
commitment  to sell  the same or a  comparable  security  at a  future  date and
specified price. These types of transactions are executed simultaneously in what
are known as "dollar-rolls", "cash

Statement of Additional Information                                            3

and carry" or financing  transactions.  For example, a broker-dealer may seek to
purchase  a  particular  security  that the Fund  owns.  The Fund will sell that
security to the broker-dealer and simultaneously enter into a forward commitment
agreement to buy it back at a future date.  This type of  transaction  generates
income for the Fund if the dealer is willing  to execute  the  transaction  at a
favorable price in order to acquire a specific security.

There is a risk  that  the  party  with  whom the  Fund  enters  into a  forward
commitment agreement will not uphold its commitment,  which could cause the Fund
to miss a favorable price or yield opportunity or to suffer a loss.

INTEREST RATE RESETS ON VARIABLE- AND
FLOATING-RATE INSTRUMENTS

The interest  rate on variable-  and  floating-rate  instruments  is  ordinarily
determined by reference to (or is a percentage of) an objective standard.  There
are  two  types  of  indexes   that   provide  the  basis  for   interest   rate
adjustments--those based on market rates and those based on a calculated measure
such as a  cost-of-funds  index.  Commonly used indexes  include the three-month
Treasury bill rate, the Federal Funds effective rate (the "Fed Funds rate"),  or
the one-month or  three-month  London  Interbank  Offered Rate (LIBOR),  each of
which is highly correlated with changes in market interest rates.

Three-month  Treasury bill rates are  calculated by the Federal  Reserve Bank of
New York based on weekly auction averages.

LIBOR is the rate at which banks in London offer  Eurodollars  in trades between
banks.  LIBOR has become a key rate in the U.S. domestic money market because it
is perceived to reflect the true global cost of money.

The Fed Funds  rate is the  overnight  rate at which  banks  lend  funds to each
other, usually as unsecured loans from regional banks to money center banks. The
Fed Funds rate is the average  dollar-weighted  rate of overnight  funds.  It is
reported with a one-day lag (Monday's rate is reported  Tuesday morning) and may
be found in reports issued by various financial information services.

The Manager may invest in instruments  whose interest rate adjustments are based
on new indexes as these indexes become available.

Variable-rate  demand instruments include master demand notes. These obligations
permit the Fund to invest  amounts that may change daily  without  penalty under
direct arrangements between the Fund and the issuer.

The issuer  normally has a  corresponding  right,  after a given period and on a
specified number of days notice,  to prepay the outstanding  principal amount of
the obligation plus accrued interest.  Although there is no secondary market for
master demand notes, these instruments are repayable by the borrower at par plus
accrued interest on seven days' notice.

Variable- and  floating-rate  demand  instruments  frequently are not rated. The
Fund may invest in these unrated instruments if the Manager  determines,  at the
time of investment,  that they are of a quality  comparable to other obligations
the Fund buys.

LOAN PARTICIPATIONS

Although  the  Fund  does  not  currently  intend  to do  so,  it may  buy  loan
participations,  which  represent  interests  in  the  cash  flow  generated  by
commercial loans. Each loan participation  requires three parties: a participant
(or investor), a lending bank, and a borrower. The investor purchases a share in
a loan  originated  by a  lending  bank,  and this  participation  entitles  the
investor to a percentage  of the  principal  and interest  payments  made by the
borrower.

Loan  participations  are attractive  because they typically offer higher yields
than other money market  instruments.  However,  along with these higher  yields
come certain  risks,  not least of which is the risk that the  borrower  will be
unable to repay the loan.  Generally,  since the lending bank does not guarantee
payment,  the investor is directly  exposed to risk of default by the  borrower.
Secondly,   the  investor  is  not  a  direct  creditor  of  the  borrower.  The
participation represents an interest in assets owned by the lending bank. If the
lending bank becomes  insolvent,  the investor  could be considered an unsecured
creditor  of the bank  instead of the holder of a  participating  interest  in a
loan.   Because  of  these  risks,  the  Manager  must  carefully  consider  the
creditworthiness of both the borrower and the lender.

Another concern is liquidity.  Because there is no established  secondary market
for loan  participations,  the Fund's  ability to sell them for cash is limited.
Some  participation  agreements  place  limitations on 

4                                                   American Century Investments

the investor's right to resell the loan participation,  even when a buyer can be
found.  To alleviate  these liquidity  concerns,  the Fund generally  limits its
investments  in loan  participations  to  those  with  terms  of 7 days or less,
although it may invest in loan participations with terms of up to 30 days.

SECURITIES LENDING

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

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

ILLIQUID SECURITIES

Illiquid  securities are  investments  that cannot be sold or disposed of in the
ordinary  course of  business  at  approximately  the  prices at which  they are
valued. Pursuant to guidelines established by the board of trustees, the Manager
determines the liquidity of the Fund's investments, and through reports from the
Manager, the board of Trustees monitors trading activity in illiquid securities.

In determining the liquidity of the Fund's investments, the Manager may consider
various factors  including (i) the frequency of trades and quotations,  (ii) the
number of dealers and prospective  purchasers in the  marketplace,  (iii) dealer
undertakings  to make a market,  (iv) the nature of the security  (including any
demand or tender features), and (v) the marketplace for trades.

In the absence of market quotations, illiquid securities are valued for purposes
of  monitoring  amortized  cost  valuation at fair market value as determined in
good faith by a committee appointed by the Board of Trustees.

RESTRICTED SECURITIES

Restricted  securities  generally  can  be  sold  (i)  in  privately  negotiated
transactions,  (ii)  pursuant  to  an  exemption  from  registration  under  the
Securities  Act of  1933,  or  (iii)  in a  registered  public  offering.  Where
registration  is  required,  the Fund may be obligated to pay all or part of the
registration  expense,  and a considerable period may elapse between the time it
decides to seek  registration  and the time it is  permitted  to sell a security
under an  effective  registration  statement.  If during  such a period  adverse
market conditions were to develop,  the Fund might obtain a less favorable price
than prevailed when it decided to seek registration of the security.

Rule 144A  under the  Securities  Act  permits a broader  institutional  trading
market for securities  otherwise subject to restriction on resale to the general
public. Rule 144A establishes a "safe harbor" from the registration requirements
of  the  Securities   Act  for  resales  of  certain   securities  to  qualified
institutional buyers. Investing in Rule 144A securities could increase the level
of fund  illiquidity to the extent that qualified  institutional  buyers become,
for a time, uninterested in purchasing these securities.

The Fund may also  invest in CP issued in reliance  on the  "private  placement"
exemption  from  registration  under Section 4(2) of the  Securities Act of 1933
(Section 4(2) paper).  Section 4(2) paper is restricted as to disposition  under
the federal  securities  laws and generally is sold to  institutional  investors
such as the Fund who agree that they are purchasing the paper for investment and
not with a view to public  distribution.  Any resale by the purchaser must be in
an  exempt  transaction.   Section  4(2)  paper  normally  is  resold  to  other
institutional  investors  like the Fund  through or with the  assistance  of the
issuer or investment  dealers who make a market in the Section 4(2) paper,  thus
providing  liquidity.  The Manager may  consider  Section  4(2) paper that meets
certain conditions to be liquid, pursuant to procedures approved by the board of
trustees.  Section 4(2) paper that is not  determined  to be liquid  pursuant to
these procedures will be included within the 10% limitation on

Statement of Additional Information                                           5

illiquid   securities.   The  Manager  monitors  the  liquidity  of  the  Fund's
investments in Section 4(2) paper on a continuing basis.

INVESTMENT RESTRICTIONS

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

AS A FUNDAMENTAL POLICY, THE FUND SHALL NOT:

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

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

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

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

5) concentrate its investments in securities of issuers in a particular industry
(other than securities issued or guaranteed by the U.S. government or any of its
agencies or  instrumentalities),  except that the Fund will invest more than 25%
of its total assets in the financial services industry.

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

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

8) invest for purposes of exercising control over management.

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

AS AN OPERATING POLICY, THE FUND:

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

b) shall not purchase or sell futures contracts or call options. This limitation
does not apply to options  attached  to, or  acquired or traded  together  with,
their underlying  securities,  and does not apply to securities that incorporate
features similar to options or futures contracts.

c) shall not purchase any security or enter into a repurchase agreement if, as a
result,  more  than  10% of its net  assets  would  be  invested  in  repurchase
agreements not entitling the holder to payment of principal and interest  within
seven days and in securities that are illiquid by virtue of legal or contractual
restrictions on resale or the absence of a readily available market.

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

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

6                                                   American Century Investments

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

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

PORTFOLIO TRANSACTIONS

The Fund's  assets are invested by the Manager in a manner  consistent  with the
Fund's   investment   objective,   policies,   and  restrictions  and  with  any
instructions  the board of  trustees  may issue from time to time.  Within  this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement securities transactions on behalf of the Fund.

In placing orders for the purchase and sale of portfolio securities, the Manager
will use its best efforts to obtain the best  possible  price and  execution and
will  otherwise  place orders with  broker-dealers  subject to and in accordance
with any  instructions  the board of trustees  may issue from time to time.  The
Manager will select  broker-dealers to execute portfolio  transactions on behalf
of the Fund solely on the basis of best price and execution.

Securities   in  which   the  Fund   invests   generally   are   traded  in  the
over-the-counter market through broker-dealers.  A broker-dealer is a securities
firm or bank that makes a market for  securities by offering to buy at one price
and sell at a slightly higher price.

The difference between the prices is known as a spread. The Manager transacts in
round lots ($1  million to $10  million or more) on behalf of the Fund  whenever
possible.  Since commissions are not charged for money market transactions,  the
Fund's  transaction  costs  consist  solely  of  custodian  charges  and  dealer
mark-ups.  The Fund may hold its portfolio securities to maturity or may sell or
swap  them for other  securities,  depending  upon the  level and slope of,  and
anticipated changes in, the yield curve.

The Fund acquired,  during the fiscal year ended  February 28, 1997,  securities
issued by its  regular  brokers or dealers  (as  defined in Rule 10b-1 under the
1940 Act) and/or their parent  corporations.  As of February 28, 1997,  the Fund
held  securities  issued by the  following  brokers or dealers in the  following
aggregate   amounts:   Merrill   Lynch,   $20,000,000,   Morgan  Stanley  Group,
$30,000,000,  Goldman Sachs Group,  $26,000,000  and BT Securities  Corporation,
$20,000,000.

VALUATION OF PORTFOLIO SECURITIES

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

Securities  held by the Fund are valued at amortized  cost. This method involves
valuing  an  instrument  at  its  cost  and   thereafter   assuming  a  constant
amortization  to  maturity  of any  discount  or  premium  paid  at the  time of
purchase.  Although this method  provides  certainty in valuation,  it generally
disregards the effect of 

Statement of Additional Information                                            7

fluctuating  interest rates on an instrument's market value.  Consequently,  the
instrument's  amortized cost value may be higher or lower than its market value,
and this  discrepancy  may be reflected in the Fund's yield.  During  periods of
declining  interest rates, for example,  the daily yield on Fund shares computed
as described above may be higher than that of a fund with identical  investments
priced at market value.  The converse would apply in a period of rising interest
rates.

The Fund operates  pursuant to Investment  Company Act Rule 2a-7,  which permits
valuation of portfolio securities on the basis of amortized cost. As required by
the Rule, the Board of Trustees has adopted procedures designed to stabilize, to
the extent reasonably  possible,  the Fund's price per share as computed for the
purposes 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  instruments  that the Board of
Trustees has determined present minimal credit risks and that have been rated in
one of the two highest rating categories as determined by a rating agency or, in
the case of unrated securities,  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 deviations should occur.

PERFORMANCE

The  Fund's  yield and total  return  may be  quoted  in  advertising  and sales
literature.  Yield and total return will vary.  Past  performance  should not be
considered an indication of future results.

Yield  quotations  are  based  on the  change  in the  value  of a  hypothetical
investment  (excluding realized gains and losses from the sale of securities and
unrealized  appreciation and depreciation of securities) over a seven-day period
(base period) and stated as a percentage  of the  investment at the start of the
base period (base-period  return).  The base-period return is then annualized by
multiplying it by 365/7 with the resulting  yield figure carried to at least the
nearest hundredth of one percent.

Calculations of effective yield begin with the same  base-period  return used to
calculate yield, but the return is then annualized to reflect weekly compounding
according to the following formula:

Effective Yield = [(Base-Period Return + 1)365/7] - 1

For the seven-day period ended February 28, 1997, the Fund's yield and effective
yield are indicated in the following table.

                                                   7-Day
                                  7-Day          Effective
                                  Yield            Yield
- ----------------------------------------------------------------
Prime                             4.94%            5.06%
- ----------------------------------------------------------------

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

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

Average annual total returns for periods of less than one year are calculated by
determining the Fund's total return for the period,  extending that return for a
full year (assuming that performance  remains constant throughout the year), and
quoting the result as an annual return. Because the Fund's return may not remain
constant over the course of a year, these  performance  figures should be viewed
as strictly hypothetical.

8                                                  American Century Investments

In addition to average  annual total returns,  the Fund may quote  unaveraged or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Average annual and cumulative total returns may be quoted
as a  percentage  or as a  dollar  amount  and may be  calculated  for a  single
investment,  a series of investments,  or a series of redemptions  over any time
period.

The Fund's  performance  may be compared  with the  performance  of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may  include  comparisons  with funds that,  unlike  American
Century funds, are sold with a sales charge or deferred sales charge. Sources of
economic  data that may be used for such  comparisons  may include,  but are not
limited to, U.S. Treasury bill, note, and bond yields, money market fund yields,
U.S.  government debt and percentage held by foreigners,  the U.S. money supply,
net  free  reserves,  and  yields  on  current-coupon  GNMAs  (source:  Board of
Governors of the Federal Reserve  System);  the federal funds and discount rates
(source:  Federal  Reserve  Bank of New York);  yield  curves for U.S.  Treasury
securities and AA/AAA-rated  corporate  securities (source:  Bloomberg Financial
Markets);  yield curves for AAA-rated  tax-free  municipal  securities  (source:
Telerate);  yield curves for foreign government  securities (sources:  Bloomberg
Financial  Markets and Data  Resources,  Inc.);  total  returns on foreign bonds
(source:  J.P.  Morgan  Securities  Inc.);  various U.S. and foreign  government
reports;  the junk bond market (source:  Data Resources,  Inc.); the CRB Futures
Index  (source:  Commodity  Index Report);  the price of gold  (sources:  London
a.m./p.m.  fixing and New York Comex Spot Price); rankings of any mutual fund or
mutual fund category tracked by Lipper Analytical Services, Inc. or Morningstar,
Inc.;   mutual  fund  rankings   published  in  major   nationally   distributed
periodicals;  data  provided  by  the  Investment  Company  Institute;  Ibbotson
Associates,  Stocks, Bonds, Bills, and Inflation;  major indexes of stock market
performance;  and  indexes and  historical  data  supplied  by major  securities
brokerage or investment  advisory firms. The Fund may also utilize reprints from
newspapers  and magazines  furnished by third  parties to illustrate  historical
performance.

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

The Manager may obtain Fund  ratings  from one or more rating  agencies  and may
publish these ratings in advertisements and sales literature.

TAXES

FEDERAL INCOME TAX

The Fund intends to qualify each year as a "regulated  investment company" under
Subchapter M of the Internal Revenue Code of 1986, as amended, (the "Code" ). To
qualify as a regulated investment company and avoid being subject to federal and
state  income  taxes at the Fund  level,  the Fund must  distribute  within each
calendar  year  as  well  as  each  fiscal  year  substantially  all of its  net
investment  income and net realized capital gains (if any) to  shareholders.  In
addition to federal income taxes, shareholders may be subject to state and local
taxes on their distributions from the Fund.

The  information  above  is only a  summary  of  some of the tax  considerations
generally  affecting the Fund and its shareholders.  No attempt has been made to
discuss individual tax consequences.

An investor considering an investment in the Fund should consult with his or her
tax advisors to determine whether the Fund is a suitable investment.

ABOUT THE TRUST

American  Century  Investment  Trust  (the  "Trust")  is a  registered  open-end
management  investment  company that was organized as a  Massachusetts  business
trust on June 16, 1993. The Trust was formerly known as Benham Investment Trust.
Currently  American  Century-Benham  Prime Money Market Fund (formerly  known as
Benham Prime Money  Market  Fund) is the only series of the Trust,  although the
trustees are authorized to create additional series at their discretion.

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

Statement of Additional Information                                            9

If  additional  series were created by the board of trustees,  each series would
vote separately on matters affecting that series exclusively.  Voting rights are
not  cumulative,  so that investors  holding more than 50% of the Trust's (i.e.,
all series')  outstanding  shares may be able to elect a board of trustees.  The
Trust instituted  dollar-based voting,  meaning that the number of votes you are
entitled to is based upon the dollar amount of your investment.  The election of
trustees is determined by the votes received from all Trust shareholders without
regard to  whether a majority  of shares of any one  series  voted in favor of a
particular nominee or all nominees as a group.

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

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

MANAGEMENT

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

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

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

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

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

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

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

The  management  agreement  also  provides  that the Manager  and its  officers,
Trustees and employees may engage in other  business,  devote time and attention
to

12                                                  American Century Investments

any other  business  whether  of a similar  or  dissimilar  nature,  and  render
services to others.

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

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

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

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

The investment  advisory fees paid by the Fund to the Manager (and its affiliate
Benham  Management  Corporation)  for the fiscal years ended  February 28, 1997,
February 29, 1996, and February 28, 1995, are indicated on the following  table.
Fee amounts are net of any amounts reimbursed or recouped.

TRANSFER AND ADMINISTRATIVE SERVICES

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

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

Transfer  agent and  administrative  agent  fees paid by the Fund for the fiscal
years ended  February 28, 1997,  and  February  29, 1996,  are  indicated in the
following table.

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

Statement of Additional Information                                           13

Due to the  expense  limitation  agreements  made  under  its  prior  investment
advisory agreement with Benham Management Corporation, the Fund paid no transfer
agent or administrative fees for the fiscal year ended February 28, 1995, or for
the period from November 17, 1993 (commencement of operations), through February
28, 1994.

DISTRIBUTION OF FUND SHARES

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

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

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

As of May 31,  1997,  to the Fund`s  knowledge,  no  shareholder  was the record
holder or beneficial owner of 5% or more of the Fund`s total shares outstanding.

American  Century may reject or limit the amount of an investment to prevent any
one shareholder or affiliated group from controlling the Trust or its series; to
avoid jeopardizing a series' tax status; or whenever,  in management's  opinion,
such rejection or limitation is in the Trust's or a series' best interest.

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

When it is in the best interest of the Fund and its  shareholders  (for example,
to deter abusive  market  timing  transactions),  the Fund may honor  redemption
requests in kind, normally by delivering  portfolio  securities in lieu of cash.
Securities  delivered as  redemptions  in kind will be valued by the same method
used to value securities in determining the Fund's NAV. Shareholders who receive
securities  may realize a capital gain or loss for tax purposes,  incur costs in
handling or disposing of the securities, or encounter other inconveniences.

SECURITIES RATINGS

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

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

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  constitute  what are  generally  known as
high-grade  bonds.  They are rated lower than the best bonds because  margins of
protection  may  not  be as  large  as in  Aaa  securities,  or  fluctuation  of
protective elements may be of greater amplitude,  or there may be other elements
present that make long-term risks appear somewhat larger than in Aaa securities.

A: Bonds that are rated "A" possess many favorable investment attributes and are
to be considered as 

14                                                  American Century Investments

upper  medium-grade  obligations.  Factors  giving  security  to  principal  and
interest  are  considered  adequate,  but elements may be present that suggest a
susceptibility to impairment sometime in the future.

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

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

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

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

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

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

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

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

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

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

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

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

Moody's  commercial  paper  ratings  are  opinions  of the ability of issuers to
punctually repay those promissory obligations that have an original maturity not
exceeding nine months. Moody's makes no representation that such obligations are
exempt from registration under the Securities Act of 1933, nor does it represent
that any  specific  note is a valid  obligation  of a rated  issuer or issued in
conformity with any applicable law. The following designations, all judged to be
investment  grade,  indicate the relative  repayment ability of rated issuers of
securities in which the Funds may invest.

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

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

Statement of Additional Information                                           15

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

INVESTMENT GRADE

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

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

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

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

SPECULATIVE

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

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

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

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

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

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

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

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

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

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

SP-1:  Issues carrying this designation have a very strong or strong capacity to
pay  principal  and interest.  Those issues  determined to possess  overwhelming
safety characteristics will be given a plus (+) designation.

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

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

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

16                                                  American Century Investments

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

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

SPECIAL MEETING OF SHAREHOLDERS

At a Special Meeting of Shareholders held on July 30, 1997,  shareholders of the
Funds approved, among other things, a new Management Agreement between the Funds
with American Century Investment Management,  Inc. This new Management Agreement
will  become  effective  on August 1, 1997,  and  replaces  the  Funds'  current
investment advisory agreement with Benham Management  Corporation,  an affiliate
of American Century Investment Management, Inc.

At the meeting, shareholders of the Funds also ratified the selection of Coopers
& Lybrand LLP as the  independent  auditors for each Fund's  current fiscal year
and approved the adoption of standardized  investment limitations by amending or
eliminating  certain of the Funds'  fundamental  investment  limitations.  These
changes are reflected in this Prospectus Supplement and in the revised Statement
of Additional Information of the Funds.

AGREEMENT AND PLAN OF REORGANIZATION

In  addition,   shareholders  of  American   Century--Benham   Intermediate-Term
Tax-Exempt Fund and American Century--Benham  Long-Term Tax-Exempt Fund approved
an Agreement and Plan of Reorganization with the Intermediate-Term  Tax-Free and
Long-Term Tax-Free,  respectively.  The reorganization  involves funds which are
identical in investment objective and investment management technique.

The Agreement was approved by shareholders  of each of American  Century--Benham
Intermediate-Term   Tax-Exempt  Fund  and  American  Century--Benham   Long-Term
Tax-Exempt Fund at a Special Meeting of Shareholders  held on July 30, 1997. The
reorganization  is  expected  to  occur  on  August  30,  1997.   Following  the
reorganization,   shareholders  of  American  Century--Benham  Intermediate-Term
Tax-Exempt Fund will own shares of Intermediate-Term Tax-Free in the same dollar
amount  as their  American  Century--Benham  Intermediate-Term  Tax-Exempt  Fund
shares at the close of business on August 30, 1997.  Likewise,  shareholders  of
American Century--Benham  Long-Term Tax-Exempt Fund will own shares of Long-Term
Tax-Free in the same dollar amount as their American  Century--Benham  Long-Term
Tax-Exempt Fund shares at the close of business on August 30, 1997.

As part of the reorganization,  shareholders of  Intermediate-Term  Tax-Free and
Long-Term  Tax-Free will notice a one-time  nominal  adjustment to the net asset
value of their shares.  This is being done to consolidate  the assets of the two
Funds.  The  dollar  value  of a  shareholder's  account,  however,  will not be
affected by the reorganization transaction.

RULE 144A SECURITIES

On page 18, the last  sentence  of the  paragraph  appearing  before the heading
"Cash Management" is deleted and the following additional paragraph is added:

     No Fund may invest  more than 15% (10% for the Money  Market  Funds) of its
net assets in illiquid securities  (securities that may not be sold within seven
days at approximately  the price used in determining the net asset value of Fund
shares).

INVESTMENT MANAGEMENT

On page 31, the first  paragraph in the  subsection  "Investment  Management" is
deleted and replaced with the following:

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

On page 31, the third full paragraph is deleted,  and the last paragraph  before
the  subsection  heading  "Code of  Ethics"  is deleted  and  replaced  with the
following:

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

     For the services  provided to the Funds, the Manager receives a monthly fee
based on a percentage of the average net assets of the Fund.  The annual rate at
which this fee is assessed is determined monthly in a two-step process: First, a
fee rate  schedule  is  applied  to the  assets  of all of the funds in a Fund's
investment  category which are managed by the Manager (the "Investment  Category
Fee"). There are three investment categories: Money Market Funds, Bond Funds and
Equity Funds.  Second,  a separate fee rate schedule is applied to the assets of
all of the  mutual  funds  managed  by the  Manager  (the  "Complex  Fee").  The
Investment  Category  Fee and the  Complex Fee are then added to  determine  the
unified  management  fee  payable  by the Fund to the  Manager.  Currently,  the
Investment  Category  Fee for each of the Funds is an annual rate of the average
net assets of the Fund as follows:  Florida  Municipal Money Market and Tax-Free
Money  Market,   0.20%;  and  Arizona   Intermediate-Term   Municipal,   Florida
Intermediate-Term Municipal,  Intermediate-Term Tax-Free and Long-Term Tax-Free,
0.22%.  The Complex Fee is  currently an annual rate of 0.30% of the average net
assets of a Fund.  Further  information  about  the  calculation  of the  annual
management fee is contained in the Statement of Additional Information.

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

TRANSFER AND ADMINISTRATIVE SERVICES

On page 32, the first paragraph under the heading  "Transfer and  Administrative
Services" is deleted and replaced with the following:

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

EXPENSES

On page 32, the subsection called "Expenses" is deleted.

INVESTMENT POLICIES AND TECHNIQUES

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

MUNICIPAL NOTES

     Municipal  notes are issued by state and local  governments  or  government
entities to provide short-term capital or to meet cash flow needs.

     TAX  ANTICIPATION  NOTES (TANs) are issued in  anticipation of seasonal tax
revenues,  such as ad valorem property,  income, sales, use, and business taxes,
and are payable from these future  taxes.  Tax  anticipation  notes  usually are
general  obligations  of the  issuer.  General  obligations  are  secured by the
issuer's  pledge of its full  faith and  credit  (i.e.,  taxing  power)  for the
payment of principal and interest.

     REVENUE  ANTICIPATION  NOTES  (RANs) are issued with the  expectation  that
receipt  of  future  revenues,  such as  federal  revenue  sharing  or state aid
payments,  will be  used  to  repay  the  notes.  Typically,  these  notes  also
constitute general obligations of the issuer.

     BOND  ANTICIPATION  NOTES  (BANs) are issued to provide  interim  financing
until long-term  financing can be arranged.  In most cases,  the long-term bonds
provide the money for repayment of the notes.

     TAX-EXEMPT  COMMERCIAL PAPER is an obligation with a stated maturity of 365
days or less issued to finance seasonal cash flow needs or to provide short-term
financing in anticipation of longer-term financing.

MUNICIPAL BONDS

     Municipal bonds, which generally have maturities of more than one year when
issued,  are designed to meet longer-term  capital needs.  These securities have
two principal classifications: general obligation bonds and revenue bonds.

     GENERAL  OBLIGATION  (GO)  Bonds are issued by  states,  counties,  cities,
towns, and regional  districts to fund a variety of public  projects,  including
construction  of and  improvements  to  schools,  highways,  and water and sewer
systems.  General  obligation  bonds are backed by the  issuer's  full faith and
credit based on its ability to levy taxes for the timely payment of interest and
repayment  of  principal,  although  such  levies  may  be  constitutionally  or
statutorily limited as to rate or amount.

     REVENUE  BONDS are not  backed by an  issuer's  taxing  authority;  rather,
interest  and  principal  are  secured  by the net  revenues  from a project  or
facility.  Revenue  bonds are issued to  finance a variety of capital  projects,
including  construction or refurbishment of utility and waste disposal  systems,
highways, bridges, tunnels, air and sea port facilities, schools, and hospitals.
Many  revenue  bond issuers  provide  additional  security in the form of a debt
service  reserve  fund  that  may be used  to  make  payments  of  interest  and
repayments  of  principal  on  the  issuer's  obligations.   Some  revenue  bond
financings are further  protected by a state's  assurance  (without  obligation)
that it will make up deficiencies in the debt service reserve fund.

     INDUSTRIAL  DEVELOPMENT BONDS (IDBs), types of revenue bonds, are issued by
or on behalf of public  authorities to finance  privately  operated  facilities.
These bonds are used to finance business, manufacturing,  housing, athletic, and
pollution  control projects as well as public  facilities,  such as mass transit
systems, air and sea port facilities,  and parking garages.  Payment of interest
and  repayment  of  principal  on an IDB  depends  solely on the  ability of the
facility's user to meet its financial  obligations and on the pledge, if any, of
the real or  personal  property  financed.  The  interest  earned on IDBs may be
subject to the federal alternative minimum tax.

VARIABLE- AND FLOATING-RATE DEMAND OBLIGATIONS

     The Funds may buy variable- and floating-rate demand obligations (VRDOs and
FRDOs).  These obligations carry rights that permit holders to demand payment of
the unpaid  principal,  plus  accrued  interest,  from the issuers or  financial
intermediaries.  Floating-rate  instruments  have  interest  rates  that  change
whenever there is a change in a designated base rate; variable-rate  instruments
provide for a specified,  periodic  adjustment  in the interest  rate,  which is
typically  based on an index.  These formulas are designed to result in a market
value for the VRDO or FRDO that approximates par value.

2                                                   American Century Investments


     The Board of Trustees  has approved  investments  in VRDOs and FRDOs on the
following conditions:

     (1) The Fund  must have an  unconditional  right to  demand  the  return of
principal plus accrued interest from the issuer on 30 days' notice or less;

     (2)  Under  the  direction  of the  Board  of  Trustees,  American  Century
Investment Management,  Inc. (the "Manager") must determine that the issuer will
be able to make  payment  upon such  demand,  either from its own  resources  or
through an  unqualified  commitment  (such as a letter of  credit)  from a third
party; and

     (3) The rate of interest  payable on the VRDO or FRDO must be calculated to
ensure  that its  market  value  will  approximate  par value on  interest  rate
adjustment dates.

OBLIGATIONS WITH TERM PUTS ATTACHED

     Each Fund may invest in fixed-rate bonds subject to third party puts and in
participation  interests  in such  bonds  held by a bank in trust or  otherwise.
These bonds and  participation  interests have tender options or demand features
that  permit  the Funds to tender  (or put)  their  bonds to an  institution  at
periodic intervals and to receive the principal amount thereof.

     The Manager  expects that the Funds will pay more for securities  with puts
attached than for securities without these liquidity  features.  The Manager may
buy  securities  with puts  attached to keep a Fund fully  invested in municipal
securities while maintaining  sufficient  portfolio liquidity to meet redemption
requests or to facilitate  management of the Funds' investments.  To ensure that
the interest on municipal securities subject to puts is tax-exempt to the Funds,
the  Manager  limits  the  Funds'  use of puts  in  accordance  with  applicable
interpretations and rulings of the Internal Revenue Service (IRS).

     Because it is  difficult  to  evaluate  the  likelihood  of exercise or the
potential  benefit of a put, puts normally will be determined to have a value of
zero,  regardless  of whether  any  direct or  indirect  consideration  is paid.
Accordingly,  puts as separate  securities are not expected to affect the Funds'
weighted average  maturities.  Where a Fund has paid for a put, the cost will be
reflected as unrealized  depreciation on the underlying  security for the period
the put is held. Any gain on the sale of the underlying security will be reduced
by the cost of the put.

     There is a risk that the seller of a put will not be able to repurchase the
underlying  obligation  when (or if) a Fund  attempts  to  exercise  the put. To
minimize such risks, the Funds will purchase obligations with puts attached only
from sellers deemed creditworthy by the Manager under the direction of the Board
of Trustees.

TENDER OPTION BONDS

     Tender  option  bonds  (TOBs) are  created by  municipal  bond  dealers who
purchase  long-term   tax-exempt  bonds  in  the  secondary  market,  place  the
certificates  in trusts,  and sell  interests  in the trusts  with puts or other
liquidity  guarantees  attached.  The credit quality of the resulting  synthetic
short-term  instrument  is based on the  guarantor's  short-term  rating and the
underlying bond's long-term rating.

     There is some risk that a remarketing  agent will renege on a tender option
agreement if the underlying bond is downgraded or defaults. Because of this, the
Manager  monitors the credit quality of bonds underlying the Funds' TOB holdings
and  intends  to sell or put back any TOB if the rating on its  underlying  bond
falls  below the second  highest  rating  category  designated  by a  nationally
recognized statistical rating agency (a "rating agency").

     The Manager  also takes steps to minimize  the risk that a Fund may realize
taxable   income  as  a  result  of  holding  TOBs.   These  steps  may  include
consideration  of (a) legal opinions  relating to the  tax-exempt  status of the
underlying  municipal bonds, (b) legal opinions relating to the tax ownership of
the underlying  bonds, and (c) other elements of the structure that could result
in taxable income or other adverse tax consequences.

     After  purchase,  the Manager  monitors  factors  related to the tax-exempt
status of the Fund's TOB  holdings in order to minimize  the risk of  generating
taxable income.

     TOBs were  created  to  increase  the  supply of  high-quality,  short-term
tax-exempt obligations,  and, thus, they are of particular interest to the Money
Market Funds. However, any of the Funds may purchase these instruments.

Statement of Additional Information                                            3


WHEN-ISSUED AND FORWARD
COMMITMENT AGREEMENTS

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

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

     In purchasing  securities on a when-issued or forward  commitment  basis, a
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash or appropriate  liquid assets in an amount sufficient to meet
the purchase price.  When the time comes to pay for the when-issued  securities,
the Fund  will  meet its  obligations  with  available  cash,  through  sales of
securities, or, although it would not normally expect to do so, through the sale
of the when-issued  securities themselves (which may have a market value greater
or  less  than  the  Fund's  payment  obligation).  Selling  securities  to meet
when-issued or forward commitment obligations may generate taxable capital gains
or losses.

     The Funds may sell a  security  and at the same time make a  commitment  to
purchase the same security at a future date and specified price. Conversely, the
Funds may purchase a security and at the same time make a commitment to sell the
same security at a future date and specified price.  These types of transactions
are   executed   simultaneously   in  what  are   known  as   "dollar-roll"   or
"cash-and-carry" transactions. For example, a broker-dealer may seek to purchase
a particular  security  that the Funds own. The Funds will sell that security to
the broker-dealer and simultaneously  enter into a forward commitment  agreement
to buy it back at a future date. This type of transaction  generates  income for
the Funds if the dealer is willing to execute  the  transaction  at a  favorable
price in order to acquire a specific security.

MUNICIPAL LEASE OBLIGATIONS

     Each Fund may invest in municipal  lease  obligations.  These  obligations,
which may take the form of a lease,  an installment  purchase,  or a conditional
sale  contract,  are issued by state and local  governments  and  authorities to
acquire land and a wide  variety of equipment  and  facilities.  Generally,  the
Funds will not hold such  obligations  directly as a lessor of the  property but
will purchase a participation  interest in a municipal  lease  obligation from a
bank or other third party.

     Municipal leases frequently carry risks distinct from those associated with
general obligation or revenue bonds. State  constitutions and statutes set forth
requirements that states and  municipalities  must meet to incur debt. These may
include  voter  referenda,  interest rate limits,  or public sale  requirements.
Leases,  installment  purchases,  or conditional sales contracts (which normally
provide for title to the leased  asset to pass to the  government  issuer)  have
evolved  as a way for  government  issuers  to acquire  property  and  equipment
without meeting  constitutional  and statutory  requirements for the issuance of
debt.

     Many leases and contracts include  nonappropriation  clauses providing that
the  governmental  issuer has no  obligation to make future  payments  under the
lease  or  contract  unless  money is  appropriated  for  such  purposes  by the
appropriate  legislative  body on a yearly or other  periodic  basis.  Municipal
lease   obligations  also  may  be  subject  to  abatement  risk.  For  example,
construction  delays or  destruction of a facility as a result of an uninsurable
disaster  that  prevents  occupancy  could result in all or a portion of a lease
payment not being made.

INVERSE FLOATERS (VARIABLE-PRICE FUNDS)

     An inverse floater is a type of derivative that bears an interest rate that
moves  inversely to market  interest  rates.  As market interest rates rise, the
interest rate on an inverse floater goes down, and vice versa. Generally this is
accomplished  by  expressing  the  interest  rate on the  inverse  floater as an
above-market  fixed  rate  of  interest,  reduced  by an  amount  determined  by
reference to a market-based or bond-specific  floating interest rate (as well as
by any fees associated with administering the inverse floater program).

4                                                   American Century Investments


     Inverse floaters may be issued in conjunction with an equal amount of Dutch
Auction  floating-rate bonds (floaters),  or a market-based index may be used to
set the interest rate on these securities.  Floaters and inverse floaters may be
brought to market by a broker-dealer  who purchases  fixed-rate bonds and places
them in a trust or by an issuer seeking to reduce  interest  expenses by using a
floater/inverse floater structure in lieu of fixed-rate bonds.

     In the  case  of a  broker-dealer  structured  offering  (where  underlying
fixed-rate bonds have been placed in a trust), distributions from the underlying
bonds are  allocated  to floater and inverse  floater  holders in the  following
manner:

     (a) Floater holders receive interest based on rates set at a Dutch Auction,
which is typically  held every 28 to 35 days.  Current and  prospective  floater
holders  bid the  minimum  interest  rate that they are willing to accept on the
floaters,  and the  interest  rate is set just high enough to ensure that all of
the floaters are sold.

     (b) Inverse floater holders receive all of the interest that remains on the
underlying bonds after floater interest and auction fees are paid.

     Procedures  for  determining  the interest  payment on floaters and inverse
floaters  brought to market directly by the issuer are comparable,  although the
interest paid on such inverse  floaters is based on a presumed  coupon rate that
would have been  required  to bring  fixed-rate  bonds to market at the time the
floaters and inverse floaters were issued.

     Where inverse  floaters are issued in conjunction  with  floaters,  inverse
floater holders may be given the right to acquire the underlying security (or to
create a fixed-rate bond) by calling an equal amount of corresponding  floaters.
The underlying security may then be held or sold.  However,  typically there are
time  constraints  and other  limitations  associated  with any right to combine
interests and claim the underlying security.

     Floater holders subject to a Dutch Auction procedure  generally do not have
the right to "put back" their  interests to the issuer or to a third party. If a
Dutch  Auction  fails,  the floater  holder may be required to hold its position
until the underlying bond matures; during which time, interest on the floater is
capped at a predetermined rate.

     The secondary market for floaters and inverse floaters may be limited.  The
market value of inverse  floaters tends to be  significantly  more volatile than
fixed-rate  bonds  because of the way  interest  payments  are  determined.  The
interest rates on inverse floaters may be significantly  reduced,  even to zero,
if interest rates rise.

RESTRICTED SECURITIES

     The Funds may buy securities  that are subject to  restrictions  on resale.
These  securities  will be deemed  illiquid  unless  (a) the  Board of  Trustees
establishes  guidelines for determining  the liquidity of restricted  securities
and (b) the  securities (on a case by case basis) are determined to be liquid in
accordance with Board-approved guidelines.

SHORT-TERM INVESTMENTS (VARIABLE-PRICE FUNDS)

     Under  certain  circumstances,  the  Variable-Price  Funds  may  invest  in
short-term  municipal  or U.S.  government  securities,  including  money market
instruments (short-term securities).  Except as otherwise required for temporary
defensive  purposes,  the  Manager  does not expect the  Funds'  investments  in
short-term  securities to exceed 35% of total assets.  If a Fund invests in U.S.
government  securities,  a portion of  dividends  paid to  shareholders  will be
taxable at the federal level, and may be taxable at the state level, as ordinary
income. The Manager intends to minimize such investments, however, and may allow
the Funds to hold  cash to avoid  generating  taxable  dividends  when  suitable
short-term municipal securities are unavailable.

     Pursuant  to  an  exemptive  order  that  the  Manager  received  from  the
Securities  and  Exchange   Commission   (SEC),  for  liquidity   purposes  each
Variable-Price Fund may invest up to 5% of its total assets in shares of a money
market fund advised by the Manager,  provided that the  investment is consistent
with the Fund's investment policies and restrictions.

CONCENTRATION OF ASSETS IN OBLIGATIONS ISSUED
TO FINANCE SIMILAR PROJECTS OR FACILITIES

     From time to time, a significant portion of a Fund's assets may be invested
in  municipal  obligations  related to the extent that  economic,  business,  or
political developments affecting one of these obligations could affect the other
obligations in a similar manner.

Statement of Additional Information                                            5


For example,  if a Fund invested a significant  portion of its assets in utility
bonds and a state or federal  government  agency or legislative body promulgated
or enacted new  environmental  protection  requirements  for utility  providers,
projects  financed by utility  bonds that a Fund holds could  suffer as a class.
Additional  financing  might be required  to comply  with the new  environmental
requirements,  and  outstanding  debt might be downgraded in the interim.  Among
other factors that could negatively affect bonds issued to finance similar types
of projects are state and federal legislation  regarding financing for municipal
projects,  pending court  decisions  relating to the validity of or the means of
financing  municipal  projects,  material or manpower  shortages,  and declining
demand for the projects or facilities financed by the municipal bonds.

FUTURES AND OPTIONS (VARIABLE-PRICE FUNDS)

     Each  Variable-Price  Fund may enter into futures  contracts,  options,  or
options on futures  contracts.  Some  futures  and options  strategies,  such as
selling  futures,  buying puts,  and writing calls,  hedge a Fund's  investments
against price fluctuations.  Other strategies,  such as buying futures,  writing
puts, and buying calls,  tend to increase market exposure.  The Funds do not use
futures and options transactions for speculative purposes.

     Although  other  techniques  may be used to  control a Fund's  exposure  to
market fluctuations,  the use of futures contracts can be a more effective means
of hedging this exposure.  While a Fund pays brokerage commissions in connection
with  opening  and closing  out  futures  positions,  these costs are lower than
transaction   costs  incurred  in  the  purchase  and  sale  of  the  underlying
securities.

     Futures Contracts provide for the sale by one party and purchase by another
party of a specific  security  at a  specified  future  time and price.  Futures
contracts  are traded on  national  futures  exchanges.  Futures  exchanges  and
trading are regulated under the Commodity  Exchange Act by the Commodity Futures
Trading  Commission  (CFTC),  a U.S.  government  agency.  A Fund may  engage in
futures and options  transactions based on securities indexes,  such as the Bond
Buyer Index of Municipal Bonds,  that are consistent with that Fund's investment
objectives.  A Fund may also engage in futures and options transactions based on
specific securities, such as U.S. Treasury bonds or notes.

     Bond Buyer Municipal Bond Index futures  contracts  differ from traditional
futures  contracts in that when  delivery  takes place,  no bonds change  hands.
Instead,  these  contracts  settle  in  cash at the  spot  market  value  of the
Municipal Bond Index. Although other types of futures contracts, by their terms,
call for actual  delivery or acceptance of the  underlying  securities,  in most
cases the  contracts  are  closed  out before  the  settlement  date.  A futures
position may be closed by taking an opposite  position in an identical  contract
(i.e.,  buying a contract  that has  previously  been sold or selling a contract
that has previously been bought).

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

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

     RISKS  RELATED TO FUTURES  AND  OPTIONS  TRANSACTIONS.  Futures and options
prices can be volatile,  and trading in these markets involves certain risks. If
the Manager  applies a hedge at an  inappropriate  time or judges  interest rate
trends incorrectly,  futures and options strategies may lower a Fund's return. A
Fund could also suffer losses if the prices of its futures and options positions
were poorly

6                                                   American Century Investments


correlated  with its other  investments,  or if it were  unable to close out its
position because of an illiquid secondary market.

     Futures  contracts  may be closed out only on an exchange  that  provides a
secondary  market for these  contracts,  and there is no assurance that a liquid
secondary  market  will  exist  for  any  particular  futures  contract  at  any
particular  time.  Consequently,  it might  not be  possible  to close a futures
position when the Manager considers it appropriate or desirable to do so. In the
event of adverse price  movements,  a Fund would be required to continue  making
daily  cash  payments  to  maintain  its  required  margin.   If  the  Fund  had
insufficient  cash,  it might have to sell  portfolio  securities  to meet daily
margin  requirements  at a time when the Manager would not otherwise elect to do
so.  In  addition,  a Fund  may be  required  to  deliver  or take  delivery  of
instruments  underlying the futures contracts it holds. The Manager will seek to
minimize  these risks by limiting the  contracts it enters into on behalf of the
Funds to those traded on national futures  exchanges and for which there appears
to be a liquid secondary market.

     A Fund  could  suffer  losses if the  prices  of its  futures  and  options
positions  were poorly  correlated  with its other  investments or if securities
underlying futures contracts purchased by the Fund had different maturities than
those of the portfolio  securities being hedged. Such imperfect  correlation may
give rise to  circumstances  in which the Fund loses money on a futures contract
at the same  time that it  experiences  a  decline  in the  value of its  hedged
portfolio securities.  The Fund could also lose margin payments it has deposited
with a margin broker if, for example, the broker becomes bankrupt.

     Most futures exchanges limit the amount of fluctuation permitted in futures
contract  prices during a single  trading day. The daily limit  establishes  the
maximum  amount that the price of a futures  contract may vary either up or down
from the previous day's settlement price at the end of the trading session. Once
the daily limit has been reached in a particular type of contract, no trades may
be made on that day at a price  beyond  the  limit.  However,  the  daily  limit
governs only price movement during a particular trading day and, therefore, does
not limit potential losses. In addition, the daily limit may prevent liquidation
of unfavorable positions. Futures contract prices have occasionally moved to the
daily  limit for  several  consecutive  trading  days with little or no trading,
thereby  preventing prompt  liquidation of futures positions and subjecting some
futures traders to substantial losses.

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

     Although  they do not  currently  intend to do so,  the Funds may write (or
sell)  call  options  that  obligate  them to sell  (or  deliver)  the  option's
underlying  instrument upon exercise of the option.  While the receipt of option
premiums would mitigate the effects of price declines, a Fund would give up some
ability to participate in a price increase on the underlying security. If a Fund
engages in options transactions, it would own the futures contract at the time a
call was  written  and would  keep the  contract  open until the  obligation  to
deliver it pursuant to the call expired.

     RESTRICTIONS   ON  THE  USE  OF  FUTURES   CONTRACTS   AND  OPTIONS.   Each
Variable-Price  Fund may enter into futures  contracts,  options,  or options on
futures contracts,  provided that such obligations represent no more than 20% of
the Fund's net assets.  Under the Commodity  Exchange Act, a fund may enter into
futures and options  transaction (a) for hedging  purposes without regard to the
percentage of assets  committed to initial margin and option premiums or (b) for
other than hedging  purposes,  provided that assets  committed to initial margin
and option  premiums  do not exceed 5% of the fund's net  assets.  To the extent
required by law, each Fund will set aside cash or appropriate liquid assets in a
segregated  account to cover its  obligations  related to futures  contracts and
options.

     The  Funds  intend  to  comply  with  tax  rules  applicable  to  regulated
investment  companies,  including a requirement that capital gains from the sale
of securities held less than three months constitute less than

Statement of Additional Information                                            7


30% of a  Fund's  gross  income  for each  fiscal  year.  Gains on some  futures
contracts and options are included in this 30% calculation,  which may limit the
Funds' investments in such instruments.

OTHER INVESTMENT COMPANIES

     Each Fund may invest in securities issued by open and closed-end investment
companies  advised  by the  Manager  which are  consistent  with its  investment
objective  and  policies.   Under  the  Investment  Company  Act  of  1940  (the
"Investment Company Act"), the Fund's investment in such securities,  subject to
certain exceptions,  currently is limited to (a) 3% of the total voting stock of
any one investment company,  (b) 5% of the Fund's net assets with respect to any
one  investment  company and (c) 10% of the Fund's net assets in the  aggregate.
Such  purchases will be made in the open market where no commission or profit to
a sponsor or dealer results from the purchase other that the customary  brokers'
commissions.  As a shareholder of another investment company, a Fund would bear,
along  with other  shareholders,  its pro rata  portion of the other  investment
company's expenses, including advisory fees. These expenses would be in addition
to the management  fee that each Fund bears directly in connection  with its own
operations.

SPECIAL CONSIDERATIONS REGARDING
ARIZONA MUNICIPAL SECURITIES

     As briefly discussed in the Prospectus,  the Arizona Fund is susceptible to
political,  economic,  and  regulatory  events  that  affect  issuers of Arizona
municipal obligations.  The following information about risk factors is provided
in view of the  Arizona  Fund's  policy of  concentrating  its assets in Arizona
municipal  securities.  This information is based on certain official statements
of the state of Arizona  published in  connection  with the issuance of specific
Arizona municipal  securities as well as from other publicly  available sources.
It does not  constitute  a  complete  description  of the risk  associated  with
investing  in  securities  of these  issuers.  While  BMC has not  independently
verified the information contained in the official statements,  it has no reason
to believe the information is inaccurate.

     Located in the  country's  sunbelt,  Arizona has been,  and is projected to
continue to be, one of the faster growing areas in the United  States.  Over the
last several  decades,  the state has outpaced most other regions of the country
in population and personal income growth, gross state product, and job creation.

     Geographically,  Arizona is the nation's  sixth  largest  state in terms of
area. It is divided into three distinct  topographic regions: the northern third
which is high plateau  country  traversed by deep canyons,  such as Grand Canyon
National  Park;  central  Arizona  which is  rugged,  mountainous,  and  heavily
forested;  and the  southern  third  which  encompasses  desert  areas and flat,
fertile  agricultural  lands  in  valleys  between  mountains  rich  in  mineral
deposits.  These  topographic  areas all have  different  climates,  which  have
distinctively  influenced  development in each region.  Land ownership is vested
largely  in the  federal  and  state  governments:  32% is owned by the  federal
government,  28% is held as  Federal  Trust  Land  (Indian),  17% is in  private
ownership, and 13% is held by the state, leaving approximately 10% held in other
categories.

     Over the last  twenty-five  years,  the state's  emphasis on the mining and
agricultural  employment sectors has diminished,  and significant job growth has
occurred in the areas of aerospace and high technology,  construction,  finance,
insurance,  and real estate.  Arizona's  economy has continued to grow in recent
years,  although  at a slower  rate of growth  than was  experienced  in earlier
periods.

     Under its  constitution,  the state of  Arizona is not  permitted  to issue
general  obligation  bonds  secured  by the full  faith and credit of the state.
However,  certain agencies and  instrumentalities of the state are authorized to
issue bonds secured by revenues from specific  projects and activities,  and the
state  and local  governmental  units may enter  into  lease  transactions.  The
particular source of payments and security for an Arizona  municipal  obligation
is detailed in the instruments themselves and in related offering materials.

     The state and local governmental  units are subject to limitations  imposed
by Arizona law with respect to ad valorem  taxation,  bonded  indebtedness,  the
amount of annual  increases in taxes, and other matters.  These  limitations may
affect the  ability of the issuers to  generate  revenues to satisfy  their debt
obligations.  There are periodic  attempts in the form of voter  initiatives and
legislative  proposals to further limit the amount of annual  increases in taxes
that may

8                                                   American Century Investments


be levied without voter approval.  If such a proposal were enacted,  there might
be an adverse impact on state or local government financing.

     Arizona is required by law to maintain a balanced budget.  In the past, the
state has used a combination  of spending  reductions and tax increases to avoid
potential budgetary shortfalls and may be required to do so again in the future.

SPECIAL CONSIDERATIONS REGARDING
FLORIDA MUNICIPAL SECURITIES

     As briefly  discussed in the Prospectus,  the Florida Funds are susceptible
to political,  economic,  and  regulatory  events that affect issuers of Florida
municipal obligations.  The following information about risk factors is provided
in view of the Florida Funds' policies of concentrating  their assets in Florida
municipal securities.  This information is based on independent municipal credit
reports  relating to securities  offerings of Florida issuers and other publicly
available  sources.  It does not  constitute a complete  description of the risk
associated  with  investing in  securities of these  issuers.  While BMC has not
independently  verified  this  information,  it has no  reason  to  believe  the
information is inaccurate.

     Because the Florida Funds invest primarily in Florida municipal securities,
they will be affected by political  and  economic  conditions  and  developments
within the state of Florida.  In general,  the credit quality and credit risk of
any  issuer's  debt  depend on the state and local  economy,  the  health of the
issuer's  finances,  the amount of the issuer's debt, the quality of management,
and the  strength  of legal  provisions  in debt  documents  that  protect  debt
holders.  Credit risk is usually lower  whenever the economy is strong,  growing
and  diversified,  financial  operations  are  sound,  and the  debt  burden  is
reasonable.

     The state of Florida's  economy is characterized by a large service sector,
a dependence on the tourism and construction industries,  and a large retirement
population.  The management of rapid growth has been the major challenge  facing
state and local governments.  Florida's  population has grown rapidly and is now
the fourth  largest state;  this growth is expected to continue,  but at reduced
rates.  The retiree  component is expected to continue to be a major factor.  As
this growth continues, particularly within the retirement population, the demand
for both public and private services will increase, which may strain the service
sector's capacity and impede the state's budget balancing efforts.

     In recent years,  the Florida economy has been  transforming  from a narrow
base of agriculture and seasonal tourism into a service and trade economy,  with
substantial  insurance,  banking,  and export  participation  as well as greater
year-round  attraction.  The  outlook  for  the  Florida  economy  is  continued
expansion  fueled by  population  growth  but at a slower  rate than that of the
1980s.

     Debt levels in the state of Florida are  moderate to high,  reflecting  the
tremendous capital demands  associated with rapid population growth.  Florida is
unusual among states in that all general  obligation  full faith and credit debt
issues  of  municipalities  must be  approved  by  public  referendum  and  are,
therefore, relatively rare. Most debt instruments issued by local municipalities
and authorities have a narrower pledge of security,  such as a sales tax stream,
special  assessment  revenue,  user fees,  utility taxes, or fuel taxes.  Credit
quality of such debt instruments tends to be somewhat lower than that of general
obligation  debt.  The state of Florida  issues  general  obligation  debt for a
variety of purposes; however, the state constitution requires a specific revenue
stream to be pledged to state general obligation bonds as well.

     The state of Florida is heavily  dependent  upon sales tax, which makes the
state's  general fund  vulnerable  to recession  and  presents  difficulties  in
expanding  the tax base in an  economy  increasingly  geared to  services.  This
dependence  upon sales tax,  combined with economic  recession,  has resulted in
budgetary  shortfalls  in the past;  Florida has reacted to preserve an adequate
financial position primarily through  expenditure  reductions.  State officials,
however, still face tremendous capital and operating pressures due to the growth
that will continue to strain the state's narrow revenue base. Future budgets may
require a wider revenue base to meet such demands; the most likely candidate for
such  revenue  enhancement  is a tax on  consumer  services.  The  creation of a
Florida personal income tax is a remote possibility  because it would require an
amendment to the state's constitution. However, there can be no assurance that a
personal income tax will not be implemented in the

Statement of Additional Information                                            9


future if such a tax were to be imposed,  there is no  assurance  that  interest
earned on Florida municipal obligations would be exempt from this tax.

INVESTMENT RESTRICTIONS

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

     AS A FUNDAMENTAL POLICY, EACH FUND SHALL NOT:

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

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

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

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

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

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

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

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

     AS AN OPERATING POLICY, EACH FUND:

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

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

     c) [Money  Market Funds only] shall not purchase or sell futures  contracts
or call  options.  This  limitation  does not apply to options  attached  to, or
acquired or traded  together with,  their  underlying  securities,  and does not
apply to  securities  that  incorporate  features  similar to options or futures
contracts.

     d) shall not purchase any security or enter into a repurchase agreement if,
as a result,  more than 15% of its net assets (10% for the 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.

     e) 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.

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

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

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

     For purposes of the Funds' investment restrictions, the party identified as
the "issuer" of a municipal  security  depends on the form and conditions of the
security.  When the assets and revenues of a political  subdivision are separate
from those of the government  that created the  subdivision  and the security is
backed only by the assets and revenues of the  subdivision,  the  subdivision is
deemed the sole issuer.  Similarly, in the case of an IDB, if the bond is backed
only by the assets and revenues of a nongovernmental  user, the  nongovernmental
user  would be  deemed  the sole  issuer.  If,  in  either  case,  the  creating
government or some other entity guarantees the security,  the guarantee would be
considered  a  separate  security  and  would  be  treated  as an  issue  of the
guaranteeing entity.

PORTFOLIO TRANSACTIONS

     Each Fund's assets are invested by the Manager in a manner  consistent with
the Fund's  investment  objectives,  policies,  and  restrictions,  and with any
instructions  the Board of  Trustees  may issue from time to time.  Within  this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement securities transactions on behalf of the Funds.

     In placing  orders for the purchase and sale of portfolio  securities,  the
Manager  will  use its best  efforts  to  obtain  the best  possible  price  and
execution and will otherwise place orders with broker-dealers  subject to and in
accordance  with any  instructions  the Board of Trustees may issue from time to
time. The Manager will select  broker-dealers to execute portfolio  transactions
on behalf of the Funds solely on the basis of best price and execution.

     The portfolio turnover rates for each of the Variable-Price Funds appear in
the  Financial  Highlights  appearing  in the  Prospectuses.  Because  a  higher
turnover  rate  increases  transaction  costs and may increase  taxable  capital
gains,  the  Manager  carefully  weighs the  potential  benefits  of  short-term
investing against these considerations.

VALUATION OF PORTFOLIO SECURITIES

     Each  Fund's  net asset  value per share  ("NAV") is  calculated  as of the
close of business of the New York Stock Exchange (the  "Exchange")  usually at 3
p.m.  Central time each day the Exchange is open for business.  The Exchange has
designated the following  holiday  closings for 1997: New Year's Day (observed),
Martin Luther King Jr. Day, Presidents' Day, Good

Statement of Additional Information                                           11


Friday,  Memorial Day, Independence Day, Labor Day, Thanksgiving,  and Christmas
(observed).  Although the Funds expect the same holiday  schedule to be observed
in the future, the Exchange may modify its holiday schedule at any time.

     Each Fund's share price is  calculated by adding the value of all portfolio
securities and other assets,  deducting liabilities,  and dividing the result by
the number of shares  outstanding.  Expenses  and  interest  earned on portfolio
securities are accrued daily.

     MONEY MARKET FUNDS. Securities held by the Money Market Funds are valued at
amortized  cost.  This method  involves  valuing an  instrument  at its cost and
thereafter  assuming a constant  amortization  to  maturity  of any  discount or
premium paid at the time of purchase. Although this method provides certainty in
valuation,  it generally  disregards the effect of fluctuating interest rates on
an instrument's  market value.  Consequently,  the  instrument's  amortized cost
value may be higher or lower than its market value,  and this discrepancy may be
reflected in the Fund's yield.  During periods of declining  interest rates, for
example,  the daily yield on Fund  shares  computed  as  described  above may be
higher than that of a fund with  identical  investments  priced at market value.
The converse would apply in a period of rising interest rates.

     The amortized  cost valuation  method is permitted in accordance  with Rule
2a-7 under the Investment Company Act. Under the Rule, a fund holding itself out
as a money  market fund must adhere to certain  quality  and  maturity  criteria
which are described in the Prospectus.

     Each Money Market Fund  operates  pursuant to  Investment  Company Act Rule
2a-7, which permits valuation of portfolio  securities on the basis of amortized
cost.  As required by the Rule,  the Board of  Trustees  has adopted  procedures
designed to stabilize,  to the extent reasonably possible, each Fund's price per
share as computed for the purpose of sales and  redemptions at $1.00.  While the
day-to-day operation of each Fund has been delegated to the Manager, the quality
requirements   established  by  the  procedures  limit  investments  to  certain
instruments  that the Board of Trustees has  determined  present  minimal credit
risks and that have been rated in one of the two highest  rating  categories  as
determined  by a rating  agency  or,  in the  case of an  unrated  security,  of
comparable  quality.  The  procedures  require  review of each 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.

     VARIABLE-PRICE  FUNDS. Most securities held by the Variable-Price Funds are
priced by an independent pricing service, provided that such prices are believed
by the Manager to reflect the fair market value of portfolio securities. Because
there are  hundreds  of  thousands  of  municipal  issues  outstanding,  and the
majority of them do not trade daily, the prices provided by pricing services are
generally  determined  without  regard to bid or last sale  prices.  In  valuing
securities,  the  pricing  services  take  into  account  institutional  trading
activity,  trading in similar groups of securities, and any developments related
to  specific  securities.  The  methods  used  by the  pricing  service  and the
valuations  so  established  are  reviewed  by the  Manager  under  the  general
supervision  of the Board of  Trustees.  There are a number of pricing  services
available,  and the  Manager,  on the  basis  of  ongoing  evaluation  of  these
services,  may use other pricing  services or discontinue the use of any pricing
service in whole or in part.

     Securities  not priced by a pricing  service are valued at the mean between
the most recently  quoted bid and asked prices provided by  broker-dealers.  The
municipal bond market is typically a "dealer  market";  that is, dealers buy and
sell bonds for their own accounts  rather than for customers.  As a result,  the
spread, or difference  between bid and asked prices, for certain municipal bonds
may differ substantially among broker-dealers.

     Securities  maturing  within 60 days of the valuation date may be valued at
amortized cost, which is plus or minus any amortized discount or premium, unless
the Trustees  determine  that this would not result in fair valuation of a given
security.  Other  assets and  securities  for which  quotations  are not readily
available  are valued in good faith at their fair  market  value  using  methods
approved by the Board of Trustees.

PERFORMANCE

     The Funds may quote  performance  in various ways.  Historical  performance
information  will  be  used  in  advertising  and  sales  literature  and is not
indicative of future results. A Fund's share price,  yield, and return will vary
with changing market conditions.

     For the MONEY MARKET FUNDS, yield quotations are based on the change in the
value of a hypothetical investment (excluding realized gains and losses from the
sale of securities and unrealized  appreciation  and depreciation of securities)
over a  seven-day  period  (base  period)  and  stated  as a  percentage  of the
investment at the start of the base period (base-period return). The base-period
return is then  annualized by multiplying it by 365/7,  with the resulting yield
figure carried to at least the nearest hundredth of one percent.

     Calculations of effective yield begin with the same base-period return used
to  calculate  yield,  but the  return  is then  annualized  to  reflect  weekly
compounding according to the following formula:

     Effective Yield = [(Base-Period Return + 1)365/7] - 1

     The Money  Market  Funds'  yields and  effective  yields for the  seven-day
period ended November 30, 1996 are listed in the following table:

                                   7-Day Yield        7-Day Effective Yield
- -----------------------------------------------------------------------------

Florida Municipal Money Market        3.60%                   3.67%
- -----------------------------------------------------------------------------

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

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

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

     The  Variable-Price  Funds' yields for the 30-day period ended November 30,
1996 are listed in the following table:

                                                      30-Day Yield

- -----------------------------------------------------------------------------
*period ended October 31, 1996

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

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

     The  Limited-Term  Fund's average annual total returns for the one-year and
life-of-fund  period ended  October 31, 1996 are 4.26% and 4.23%,  respectively.
The inception date of the Limited-Term Fund is March 1, 1993.

     The  remaining  Funds'  average  annual  total  returns  for the  one-year,
five-year,  ten-year and  life-of-fund  periods  ended  November  30, 1996,  are
indicated in the following table.

     In addition to average annual total returns, each Fund may quote unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment over a stated period. Average annual and cumulative total returns may
be quoted as a  percentage  or as a dollar  amount and may be  calculated  for a
single investment, a series of investments,  or a series of redemptions over any
time period.  Total  returns may be broken down into their  components of income
and capital  (including  capital gains and changes in share price) to illustrate
the  relationship  of these  factors and their  contributions  to total  return.
Performance  information  may be quoted  numerically  or in a table,  graph,  or
similar illustration.

     Each Fund may also quote  tax-equivalent  yields,  which  show the  taxable
yields an investor would have to earn before taxes to equal the Fund's  tax-free
yields.  As a prospective  investor in the Funds, you should  determine  whether
your  tax-equivalent  yield is  likely to be  higher  with a  taxable  or with a
tax-exempt Fund. To determine this, you may use the formula depicted below.

     You can calculate your tax-equivalent yield for a Fund (taking into account
only  federal  income  taxes  and not any  applicable  state  taxes)  using  the
following equation:

        Fund's Tax-Free Yield       Your Tax-
     -------------------------- =  Equivalent
       100% - Federal Tax Rate        Yield

     The Funds' performance may be compared with the performance of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may  include  comparisons  with funds that,  unlike  American
Century family of funds,  are sold with a sales charge or deferred sales charge.
Sources of economic data that may be used for such comparisons may include,  but
are not limited to, U.S. Treasury bill, note, and bond yields, money market fund
yields, U.S.  government debt and percentage held by foreigners,  the U.S. money
supply, net free reserves,  and yields on current-coupon GNMAs (source: Board of
Governors of the Federal Reserve  System);  the federal funds and discount rates
(source:  Federal  Reserve  Bank of New York);  yield  curves for U.S.  Treasury
securities and AA/AAA-rated  corporate  securities (source:  Bloomberg Financial
Markets);  yield curves for AAA-rated  tax-free  municipal  securities  (source:
Telerate);  yield curves for foreign government  securities (sources:  Bloomberg
Financial  Markets and Data  Resources,  Inc.);  total  returns on foreign bonds
(source:  J.P.  Morgan  Securities  Inc.);  various U.S. and foreign  government
reports;  the junk bond market (source:  Data Resources,  Inc.); the CRB Futures
Index  (source:  Commodity  Index Report);  the price of gold  (sources:  London
a.m./p.m.  fixing and New York Comex Spot Price); rankings of any mutual fund or
mutual fund category tracked by Lipper Analytical Services, Inc. or Morningstar,
Inc.;   mutual  fund  rankings   published  in  major   nationally   distributed
periodicals;  data  provided  by  the  Investment  Company  Institute;  Ibbotson
Associates,  Stocks, Bonds, Bills, and Inflation;  major indexes of stock market
performance;  and  indexes and  historical  data  supplied  by major  securities
brokerage or investment advisory firms. The Funds may also utilize reprints from
newspapers  and magazines  furnished by third  parties to illustrate  historical
performance.

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

TAXES

FEDERAL INCOME TAX

     Each Fund intends to qualify annually as a "regulated  investment  company"
under  Subchapter  M of the  Internal  Revenue  Code of 1986,  as  amended  (the
"Code").  By so  qualifying,  the Funds will not incur  federal or state  income
taxes on its net  investment  income and on net  realized  capital  gains to the
extent distributed as dividends to shareholders.

     It is intended  that each Fund's  assets will be  sufficiently  invested in
municipal securities to qualify to

14                                                  American Century Investments


pay  "exempt-interest  dividends"  (as defined in the Code) to  shareholders.  A
Fund's  dividends  payable from net  tax-exempt  interest  earned from municipal
securities  will qualify as  exempt-interest  dividends if, at the close of each
quarter  of its  taxable  year,  at least 50% of the  value of its total  assets
consists of  municipal  securities.  Exempt-interest  dividends  distributed  to
shareholders are not included in shareholders'  gross income for purposes of the
regular  federal  income tax. The  percentage  of income that is  tax-exempt  is
applied  uniformly to all  distributions  made during each calendar  year.  This
percentage may differ from the actual  percentage of tax-exempt  income received
during any particular month.

     Each  Fund  will  determine   periodically  which   distributions  will  be
designated  as  exempt-interest  dividends.  If a Fund earns income which is not
eligible to be designated as exempt-interest  dividends,  the Fund, nonetheless,
intends  to  distribute  such  income.  Such  distributions  will be  subject to
federal, state, and local taxes, as applicable, in the hands of shareholders.

     Distributions  of net investment  income received by a Fund from investment
in debt  securities  other  than  municipal  securities  and  any  net  realized
short-term capital gains distributed by the Fund will be taxable to shareholders
as  ordinary  income.  Because  the Funds'  investment  income is  derived  from
interest rather than dividends, no portion of such distributions is eligible for
the dividends-received deduction available to corporations.

     The timing of your investment could have undesirable tax  consequences.  If
you open an account or buy shares for your account  before the day a dividend or
distribution  is declared,  you may receive a portion of your investment back as
taxable  income  if that  dividend  or  distribution  is not an  exempt-interest
dividend.

     Under the Code,  any  distribution  from a fund's  net  realized  long-term
capital gains is taxable to shareholders as a long-term capital gain, regardless
of the length of time shares have been held.

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

     Upon the sale or exchange of a Fund's shares, a shareholder  generally will
realize a taxable gain or loss depending upon his/her basis in the shares.  Such
gain or loss will be treated as a capital gain or loss if the shares are capital
assets in the  shareholder's  hands and will be long-term  if the  shareholder's
holding  period  for the  shares  is more  than one year  and,  generally,  will
otherwise be short-term.

     Any loss realized from a disposition  of Fund shares held for six months or
less will be  disallowed  to the extent that  dividends  from the Fund have been
designated as exempt-interest dividends. Any loss realized on a sale or exchange
of Fund shares also will be disallowed to the extent that the shares disposed of
are replaced (including replacement through reinvesting of dividends and capital
gain  distributions  in the Fund)  within a period of 61 days  beginning 30 days
before and ending 30 days after the  disposition of the shares.  In such a case,
the basis of the shares  acquired  will be adjusted  to reflect  the  disallowed
loss.

     Interest on certain  types of  industrial  development  bonds is subject to
federal income tax when received by  "substantial  users" or persons  related to
substantial users as defined in the Code. The term  "substantial  user" includes
any  "nonexempt  person"  who  regularly  uses in  trade or  business  part of a
facility financed from the proceeds of industrial  development  bonds. The Funds
may invest periodically in industrial development bonds and, therefore,  may not
be appropriate investments for entities that are substantial users of facilities
financed by industrial  development  bonds or "related  persons" of  substantial
users.  Generally,  an individual  will not be a related person of a substantial
user under the Code unless

Statement of Additional Information                                           15


he/she or  his/her  immediate  family  (spouse,  brothers,  sisters,  and lineal
descendants)  owns  directly or  indirectly  in  aggregate  more than 50% of the
equity value of the substantial user.

     Certain  options,  futures  contracts,  and forward  contracts in which the
Funds may invest are "section 1256  contracts."  Gains or losses on section 1256
contracts  generally are  considered  60% long-term and 40%  short-term  capital
gains or losses (60-40).  Also, section 1256 contracts held by a Fund at the end
of each taxable year (and, in some cases,  for purposes of the 4% excise tax, on
October 31st of each year) are marked to market with the result that  unrealized
gains or losses are treated as though they were realized.

     The hedging  transactions  undertaken  by the Funds may result in straddles
for federal income tax purposes.  The straddle rules may affect the character of
gains (or losses) realized by a fund. In addition,  losses realized by a fund on
positions that are part of a straddle may be deferred under the straddle  rules,
rather than being taken into account in  calculating  the taxable income for the
taxable year in which such losses are realized.  Because only a few  regulations
implementing the straddle rules have been  promulgated,  the tax consequences to
the  Funds  of  hedging   transactions  are  not  entirely  clear.  The  hedging
transactions may increase the amount of short-term capital gains realized by the
Funds, which are taxed as ordinary income when distributed to shareholders.

     Each Fund may make one or more of the  elections  available  under the Code
that are  applicable to  straddles.  If a Fund makes any of the  elections,  the
amount,  character,  and timing of the  recognition  of gains or losses from the
affected  straddle  positions will be determined under rules that vary according
to the elections made. The rules  applicable  under certain of the elections may
operate to  accelerate  the  recognition  of gains or losses  from the  affected
straddle positions.

     Because application of the straddle rules may affect the character of gains
or losses,  defer losses,  and/or  accelerate the recognition of gains or losses
from the affected  straddle  positions,  the amount that must be  distributed to
shareholders  and that will be taxed to  shareholders as ordinary income or as a
long-term  capital gain may be increased or decreased  substantially as compared
to a fund that did not engage in such hedging transactions.

     Opinions  relating to the tax status of interest  derived  from  individual
municipal  securities are rendered by bond counsel to the issuer. The Funds, the
investment  manager,  and the  Funds'  counsel  do not  review  the  proceedings
relating to the issuance of state or municipal  securities  on the basis of bond
counsel opinions.

     From time to time,  proposals  have been  introduced  in  Congress  for the
purpose of  restricting  or  eliminating  the federal  income tax  exemption for
interest on municipal securities, and similar proposals may be introduced in the
future.  If  such  a  proposal  were  enacted,  the  availability  of  municipal
securities  for  investment  by the Funds and the Funds' NAVs would be adversely
affected. Under these circumstances, the Board of Trustees would re-evaluate the
Funds'  investment  objectives and policies and would consider either changes in
the structure of the Trust or its dissolution.

     The information  above is only a summary of some of the tax  considerations
affecting the Funds and their shareholders.  No attempt has been made to discuss
individual  tax  consequences.  To  determine  whether  a  Fund  is  a  suitable
investment  based on his or her  situation,  a prospective  investor may wish to
consult a tax advisor.

ALTERNATIVE MINIMUM TAX

     While the  interest on bonds  issued to finance  essential  state and local
government operations is generally tax-exempt,  interest on certain nonessential
or private activity securities issued after August 7, 1986, while tax-exempt for
regular  federal  income tax  purposes,  constitutes a  tax-preference  item for
taxpayers in determining  alternative  minimum tax liability  under the Code and
income tax  provisions  of several  states.  The  interest  on private  activity
securities  could subject a shareholder  to, or increase  liability  under,  the
federal alternative minimum tax, depending on the shareholder's tax situation.

     All distributions  derived from interest exempt from regular federal income
tax may subject  corporate  shareholders  to, or increase their liability under,
the  alternative  minimum tax because  these  distributions  are included in the
corporation's adjusted current earnings.

16                                                  American Century Investments


     The Trust will  inform  shareholders  annually  as to the dollar  amount of
distributions derived from interest payments on private activity securities.

STATE AND LOCAL TAXES (ARIZONA FUND)

     Under a ruling by the Arizona  Department of Revenue,  shareholders who are
otherwise  subject  to  Arizona  income  tax will not be  subject to such tax on
dividends  paid by the  Arizona  Fund to the  extent  that  such  dividends  are
attributable  to either (a) obligations of the State of Arizona or its political
subdivisions  thereof  or (b)  obligations  issued by the  governments  of Guam,
Puerto Rico, or the Virgin Islands.  In addition,  dividends paid by the Arizona
Fund that are  attributable  to interest  payments on direct  obligations of the
United States  government  will not be subject to Arizona  income tax so long as
the Arizona Fund qualifies as a regulated  investment company under Subchapter M
of the  Code.  Other  distributions  from the  Arizona  Fund,  however,  such as
distributions  of short-term or long-term  capital gains,  will generally not be
exempt from Arizona income tax.

     The Arizona Fund's  dividends may not qualify for exemption under income or
other  tax laws of  state  or  local  taxing  authorities  outside  of  Arizona.
Shareholders should consult their tax advisors or state or local tax authorities
about the status of distributions from the Arizona Fund in this regard.

     The information  above is only a summary of some of the tax  considerations
affecting  the Arizona  Fund and its  shareholders.  No attempt has been made to
discuss individual tax consequences.  To determine whether the Arizona Fund is a
suitable investment based on his or her tax situation, a prospective shareholder
may wish to consult a tax advisor.

STATE AND LOCAL TAXES (FLORIDA FUNDS)

     Dividends and  distributions  paid by the Florida Funds to individuals  who
are Florida residents will not be subject to personal income taxation by Florida
because Florida does not have a personal income tax. Corporate shareholders that
are subject to the Florida  corporate  income tax should  consult with their tax
advisor  regarding  the  application  of the  Florida  corporate  income  tax to
dividends and distributions paid by the Florida Funds.

     The Florida  Funds may apply for rulings  from the  Florida  Department  of
Revenue  (FDR) to the effect that  shares of a Florida  Fund will be exempt from
the  Florida  intangibles  tax each  year if the  Florida  Fund's  portfolio  of
investments on January 1st of that year consists of investments  exempt from the
Florida  intangibles tax.  Investments  exempt from the Florida  intangibles tax
include,  but are not limited to, (a) notes,  bonds and other obligations issued
by the state of  Florida  or its  municipalities,  counties,  and  other  taxing
districts  and (b)  notes,  bonds,  and  other  obligations  issued  by the U.S.
government and its agencies. Obligations issued by the government of Puerto Rico
are also exempt if  permitted  by ruling.  If the Florida  Fund's  portfolio  of
investments on January 1st of each year includes investments that are not exempt
from the Florida  intangibles  tax, the Florida Fund's shares could be wholly or
partially subject to the Florida  intangibles tax. The Florida Funds intend that
on January 1st of each year, each Florida Fund's  portfolio of investments  will
consist solely of investments exempt from the Florida intangibles tax.

     The Florida Funds'  dividends may not qualify for exemption under income or
other  tax laws of  state  or  local  taxing  authorities  outside  of  Florida.
Shareholders should consult their tax advisors or state or local tax authorities
about the status of distributions from the Florida Funds in this regard.

     The information  above is only a summary of some of the tax  considerations
affecting the Florida Funds and their shareholders.  No attempt has been made to
discuss individual tax consequences.  To determine whether the Florida Funds are
a suitable investment based on his or her tax situation,  a prospective investor
may wish to consult a tax advisor.

ABOUT THE TRUST

     American  Century  Municipal Trust (the "Trust") is a registered,  open-end
management  investment  company that was organized as a  Massachusetts  business
trust on May 1, 1984 (the Trust was formerly known as "Benham  Municipal  Trust"
and "Benham National Tax-Free Trust").  Currently, there are seven series of the
Trust which are: American  Century-Benham  Arizona  Intermediate-Term  Municipal
Fund (formerly  known as "Benham  Arizona  Municipal  Intermediate-Term  Fund"),
American  Century-Benham  Florida  Municipal Money Market Fund (formerly "Benham
Florida Municipal Money Market Fund"), American

Statement of Additional Information                                           17


Century-Benham  Florida  Intermediate-Term  Municipal  Fund  (formerly  known as
"Benham Florida  Municipal  Intermediate-Term"  Fund),  American  Century-Benham
Tax-Free Money Market Fund (formerly  known as "Benham  National  Tax-Free Money
Market Fund"), American Century-Benham Intermediate-Term Tax-Free Fund (formerly
known  as  "Benham  National   Tax-Free   Intermediate-Term   Fund"),   American
Century-Benham  Limited-Term Tax-Free Fund and American Century-Benham Long-Term
Tax-Free Fund (formerly known as "Benham National Tax-Free Long-Term Fund"). The
Board of Trustees may create additional series from time to time.

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

     Each series votes separately on matters affecting that series  exclusively.
Voting rights are not cumulative, so that investors holding more than 50% of the
Trust's (i.e.,  all series')  outstanding  shares may elect a Board of Trustees.
The Trust instituted  dollar-based voting,  meaning that the number of votes you
are entitled to is based upon the dollar amount of your investment. The election
of Trustees is  determined  by the votes  received  from all Trust  shareholders
without regard to whether a majority of  shareholders of any one series voted in
favor of a particular  nominee or all nominees as a group.  Each shareholder has
equal rights to dividends and distributions  declared by the Fund and to the net
assets of such Fund upon its liquidation or dissolution  proportionate to his or
her share  ownership  interest  in the Fund.  Shares of each  series  have equal
voting rights,  although each series votes separately on matters  affecting that
series exclusively.

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

     CUSTODIAN BANKS: Chase Manhattan Bank, 4 Chase Metrotech Center,  Brooklyn,
New York 11245 and Commerce Bank, N.A., 1000 Walnut, Kansas City, Missouri 64106
serve as custodians of the Trust's  assets.  Services  provided by the custodian
banks include (a) settling  portfolio  purchases and sales, (b) reporting failed
trades,  (c)  identifying  and collecting  portfolio  income,  and (d) providing
safekeeping of securities.  The custodian  takes no part in determining a Fund's
investment  policies or in determining which securities are sold or purchased by
the Fund.

     INDEPENDENT  AUDITORS:  KPMG Peat  Marwick LLP,  1000  Walnut,  Suite 1600,
Kansas City, Missouri 64106, serve as the Trust's  independent  auditors for the
Funds (except Limited-Term Tax-Free) and audits the annual financial statements.

the Fund have selected Coopers & Lybrand LLP to serve as independent auditors of
the Funds. The address of Coopers & Lybrand LLP is City Center Square, 1100 Main
Street, Suite 900, Kansas City, Missouri 64105-2140.

Corporation, a predecessor to the Manager.

     As of May 5, 1997, the Trust's  Officer's and Trustees,  as a group,  owned
less than 1% of each Fund's total shares outstanding.

MANAGEMENT

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

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

     The schedules by which the  Investment  Category Fee are  determined are as
follows:

                               MONEY MARKET FUNDS

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

     The management  agreement shall continue in effect until the earlier of the
expiration  of two  years  from the date of its  execution  or until  the  first
meeting of  shareholders  following such execution and for as long thereafter as
its  continuance  is  specifically  approved at least annually by (1) the Funds'
Board of Trustees, or by the vote of a majority of outstanding votes (as defined
in the Investment Company Act) and (2) by the vote of a majority of the Trustees
of the 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 Trustees,  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,
trustees and employees may engage in other  business,  devote time and attention
to any other  business  whether of a similar or  dissimilar  nature,  and render
services to others.

     Certain  investments  may be  appropriate  for the 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 other  clients when the Manager  believes  that
such aggregation  provides the best execution for the Funds. The Funds' Board of
Trustees has approved the policy of the Manager with respect to the  aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the 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,  the Manager also acts as an  investment
advisor  to  12   institutional   accounts  and  to  the  following   registered
investment  companies:  American  Century Mutual Funds,  Inc.,  American Century
World Mutual Funds, Inc., American Century Premium Reserves, Inc., American

Income  Trust,  American  Century  Investment  Trust,  American  Century  Target
Maturities  Trust,  American  Century  California  Tax-Free and Municipal Funds,
American Century  Quantitative  Equity Funds and American Century  International
Bond Funds.

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

     Limited-Term  Tax-Free  paid the Manager the following  management  fees in
1996,  $205, 918 (net of fees waived by the Manager) and no management fees were
paid in 1995 and 1994 for the periods ended October 31. Investment advisory fees
paid  by  each  of  the  remaining  Funds  in the  Trust  to  Benham  Management
Corporation  for the  fiscal  periods  ended May 31,  1996,  1995,  and 1994 are
indicated in the following table.

It provides physical  facilities,  including  computer hardware and software and

Corporation  directly  for its  services  as transfer  agent and  administrative
services agent.

     Administrative  service and  transfer  agent fees paid by each Fund (except

     American Century may reject or limit the amount of an investment to prevent
any one shareholder or affiliated group from controlling the Trust or one of its
series;  to avoid  jeopardizing  a  series'  tax  status;  or  whenever,  in the
Manager's opinion, such rejection is in the Trust's or a series' best interest.

     As of May 5, 1997, to the knowledge of the Trust, the  shareholders  listed

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

     Pursuant to Rule 18f-1 under the Investment  Company Act of 1940, the Trust
has elected to pay in cash all requests for  redemption  by any  shareholder  of
record,  limited in amount with  respect to each  shareholder  during any 90-day
period to the  lesser of  $250,000  or 1% of the net assets of the Fund in which
shares are held at the beginning of such period.  This  election is  irrevocable
without the prior  approval of the  Securities  and  Exchange  Commission.  With
respect to redemption requests in excess of the above limit, it is the intention
of the Trust to make payments in cash,  although the Trustees  reserve the right
to make payments in whole or in part in securities under emergency circumstances
or when payment in cash would impair the liquidity of a Fund to the detriment of
shareholders.  In this event,  the securities would be valued in the same manner
applied in valuing  the  Funds'  assets for  purposes  of  calculating  NAV.  An
investor may incur brokerage costs upon the sale of such securities.

MUNICIPAL SECURITIES RATINGS

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

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

     Aaa: Bonds that are rated "Aaa" are judged to be of the best quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
"gilt edge." Interest payments are protected by a large or exceptionally  stable
margin,  and  principal  is secure.  While the various  protective  elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

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

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

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

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

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

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

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

     C: Bonds that are rated "C" are the lowest-rated class of bonds, and issues
so rated can be regarded as having  extremely  poor  prospects of ever attaining
any real investment standing.Note:  Moody's may apply the numerical modifier "1"
for   municipally   backed   bonds   and   modifiers   "1,"  "2,"  and  "3"  for
corporate-backed  municipal  bonds. The modifier "1" indicates that the security
ranks in the  higher  end of its  generic  rating  category;  the  modifier  "2"
indicates a mid-range  ranking,  and the modifier "3"  indicates  that the issue
ranks in the lower end of its generic rating category.

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

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

Statement of Additional Information                                           25


on fixed maturity dates and payments relying on external liquidity.

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

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

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

     Moody's  commercial paper ratings are opinions of the ability of issuers to
punctually repay those promissory obligations that have an original maturity not
exceeding nine months. Moody's makes no representation that such obligations are
exempt from registration under the Securities Act of 1933, nor does it represent
that any  specific  note is a valid  obligation  of a rated  issuer or issued in
conformity with any applicable law. The following designations, all judged to be
investment  grade,  indicate the relative  repayment ability of rated issuers of
securities in which the Funds may invest.

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

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

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

INVESTMENT GRADE

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

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

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

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

SPECULATIVE

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

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

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

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

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

     C: The "C"  rating is  typically  applied  to debt  subordinated  to senior
debt that is assigned an actual

26                                                  American Century Investments


or implied  "CCC-" debt rating.  The "C" rating may be used to cover a situation
where a  bankruptcy  petition  has been filed,  but debt  service  payments  are
continued.

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

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

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

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

     SP-1:  Issues  carrying  this  designation  have a very  strong  or  strong
capacity to pay  principal  and  interest.  Those issues  determined  to possess
overwhelming safety characteristics will be given a plus (+) designation.

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

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

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

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

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

SPECIAL MEETING OF SHAREHOLDERS

At a Special Meeting of Shareholders held on July 30, 1997,  shareholders of the
Funds approved, among other things, a new Management Agreement between the Funds
with American Century Investment Management,  Inc. This new Management Agreement
will  become  effective  on August 1, 1997,  and  replaces  the  Funds'  current
investment advisory agreement with Benham Management  Corporation,  an affiliate
of American Century Investment Management, Inc. At the meeting,  shareholders of
the  Funds  also  ratified  the  selection  of  Coopers  &  Lybrand  LLP  as the
independent  auditors  for each  Fund's  current  fiscal year and  approved  the
adoption of  standardized  investment  limitations  by  amending or  eliminating
certain of the Funds' fundamental investment limitations.  The changes resulting
from the  Special  Meeting of  Shareholders  are  reflected  in this  Prospectus
Supplement and in the revised Statement of Additional Information of the Funds.

INVESTMENT MANAGEMENT

On page 23, the first  paragraph in the  subsection  "Investment  Management" is
deleted and replaced with the following:

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

On page 24, the second full  paragraph is deleted,  and the last two  paragraphs
before the subsection heading "Code of Ethics" are deleted and replaced with the
following:

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

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

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

TRANSFER AND ADMINISTRATIVE SERVICES

On page 24, the first paragraph under the heading  "Transfer and  Administrative
Services" is deleted and replaced with the following:

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

EXPENSES

On page 25, the subsection called "Expenses" is deleted.

Statement of Additional Information                                            1


INVESTMENT POLICIES AND TECHNIQUES

     The  following  paragraphs  provide  a  more  detailed  description  of the
securities  and  investment  practices  identified  in  the  Prospectus.  Unless
otherwise  noted,  the  policies  described  in  this  Statement  of  Additional
Information are not fundamental and may be changed by the board of trustees.

LOANS OF PORTFOLIO SECURITIES

     Each Fund may lend its portfolio securities to earn additional income. If a
borrower defaults on a securities loan, the lending Fund could experience delays
in recovering  the securities it loaned;  if the value of the loaned  securities
increased  over the value of the  collateral,  the Fund could suffer a loss.  To
minimize the risk of default on securities  loans,  American Century  Investment
Management,  Inc. (the "Manager") adheres to the following guidelines prescribed
by the Board of  Trustees  governing  lending of  securities.  These  guidelines
strictly  govern (1) the type and amount of collateral  that must be received by
the Fund; (2) the circumstances under which additions to that collateral must be
made by borrowers; (3) the return received by the Fund on the loaned securities;
(4) the limitations on the percentage of Fund assets on loan; and (5) the credit
standards applied in evaluating potential borrowers of portfolio securities.  In
addition,  the guidelines require that the Fund have the option to terminate any
loan of a portfolio  security at any time and set  requirements  for recovery of
securities from borrowers.

INVESTMENT RESTRICTIONS

     The Funds'  investment  restrictions are set forth below.  These investment
restrictions  are  fundamental  and may not be changed  without  approval  of "a
majority of the outstanding  vote of  shareholders"  of a Fund, as determined in
accordance  with the  Investment  Company Act of 1940 (the  "Investment  Company
Act").

     AS A FUNDAMENTAL POLICY, EACH FUND SHALL NOT:

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

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

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

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

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

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

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

     8)  invest for purposes of exercising control over management.

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

     AS AN OPERATING POLICY, EACH FUND:

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

     b)  shall not purchase  any  security or enter into a repurchase  agreement
if,  as a  result,  more  than  15% of its  net  assets  would  be  invested  in
repurchase agreements not entitling the holder to

2                                                   American Century Investments


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.

     c) 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.

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

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

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

PORTFOLIO TRANSACTIONS

     Each Fund's assets are invested by the Manager in a manner  consistent with
the Fund's  investment  objectives,  policies,  and  restrictions,  and with any
instructions  the Board of  Trustees  may issue from time to time.  Within  this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement securities transactions on behalf of the Funds.

     In placing  orders for the purchase and sale of portfolio  securities,  the
Manager  will  use its best  efforts  to  obtain  the best  possible  price  and
execution and will otherwise place orders with broker-dealers  subject to and in
accordance  with any  instructions  the Board of Trustees may issue from time to
time. The Manager will select  broker-dealers to execute portfolio  transactions
on behalf of the Funds solely on the basis of best price and execution.

     U.S.  government  securities  generally are traded in the  over-the-counter
(OTC) market through  broker-dealers.  A  broker-dealer  is a securities firm or
bank that makes a market for securities by offering to buy at one price and sell
at a slightly  higher price.  The difference  between these prices is known as a
spread.

     The Manager  expects to execute most  transactions  on a net basis  through
broker-dealers  unless it is determined  that a better price or execution can be
obtained on a commission basis through a broker.  Portfolio  securities may also
be purchased directly from the issuer.  The Funds paid no brokerage  commissions
during the fiscal years ended September 30, 1996, 1995, and 1994.

     Each Fund may hold portfolio  securities until they mature,  or it may sell
or otherwise dispose of these  securities,  replacing them with other securities
consistent  with its  investment  objectives and policies.  The Funds'  turnover
rates for the fiscal years ended  September 30, 1996, and 1995, are indicated in
the following table.

VALUATION OF PORTFOLIO SECURITIES

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

     The  Manager  typically  completes  its  trading  on behalf of each Fund in
various  markets before the Exchange closes for the day. Each Fund's share price
is calculated by adding the value of all portfolio  securities and other assets,
deducting  liabilities,  and  dividing  the  result  by  the  number  of  shares
outstanding. Expenses and interest on portfolio securities are accrued daily.

     Most  securities  held by the Funds are priced at market value using prices
obtained from an  independent  pricing  service.  Because of the large number of
zero-coupon  Treasury  obligations  available,  many do not trade  each day.  In
valuing  these  securities,  the pricing  service  generally  takes into account
institutional  trading,  trading  in  similar  groups  of  securities,  and  any
developments related to specific securities.

     The methods used by the pricing  service and the  valuations so established
are  reviewed  by the  Manager  under the  general  supervision  of the Board of
Trustees.  There are a number of pricing services available, and the Manager, on
the  basis of  ongoing  evaluation  of these  services,  may use  other  pricing
services or discontinue the use of any pricing service in whole or in part.

     Securities  maturing  within 60 days of the valuation date may be valued at
amortized cost,  which is cost plus or minus any amortized  discount or premium,
unless the Trustees  determine that this would not result in fair valuation of a
given security. Other assets and securities for which quotations are not readily
available are valued in good faith at their fair value using methods approved by
the Board of Trustees.

PREDICTABILITY OF RETURN

     ANTICIPATED VALUE AT MATURITY. The maturity values of zero-coupon bonds are
specified at the time the bonds are issued, and this feature,  combined with the
ability to  calculate  yield to  maturity,  has made these  instruments  popular
investment vehicles for investors seeking reliable investments to meet long-term
financial goals.

     To provide a comparable investment opportunity while allowing investors the
flexibility  to  purchase  or  redeem  shares  each  day the  Trust  is open for
business,  each Fund  consists  primarily of  zero-coupon  bonds but is actively
managed to accommodate  shareholder  activity and to take advantage of perceived
market  opportunities.  Because of this active management approach,  the Manager
does not guarantee that a certain price per share will be attained by the time a
Fund is liquidated. Instead, the Manager attempts to track the price behavior of
a directly held zero-coupon bond by:

     (1) Maintaining  a weighted  average  maturity  within  the  Fund's  target
maturity year;

     (2) Investing at least 90% of assets in  securities  that mature within one
year of the Fund's target maturity year;

     (3) Investing  a  substantial  portion of assets in  Treasury  STRIPS  (the
most liquid Treasury zero);

     (4) Under normal conditions, maintaining a cash balance of less than 1%;

     (5) Executing   portfolio   transactions   necessary  to  accommodate   net
shareholder purchases or redemptions on a daily basis; and

4                                                   American Century Investments


     (6) Whenever  feasible,   contacting  several  U.S.  government  securities
dealers for each intended  transaction  in an effort to obtain the best price on
each transaction.

     These  measures  enable the advisor to  calculate an  anticipated  value at
maturity (AVM) for each Fund that approximates the price per share the Fund will
achieve  by its  weighted  average  maturity  date.  The AVM  calculation  is as
follows:

                               AVM = P(1+AGR/2)2T

where P = the Fund's  current price per share, T = the Fund's  weighted  average
term to maturity in years, and AGR = the anticipated growth rate.

     This  calculation  assumes that the shareholder  will reinvest all dividend
and capital gain  distributions (if any). It also assumes an expense ratio and a
portfolio  composition  that remain  constant for the life of the Fund.  Because
Fund  expenses and  composition  do not remain  constant,  however,  the Manager
calculates AVM for each Fund each day the Trust is open for business.

     In addition to the measures described above, which the Manager believes are
adequate to assure close correspondence  between the price behavior of each Fund
and the price  behavior  of  directly  held  zero-coupon  bonds with  comparable
maturities, the Trust has made an undertaking to the staff of the Securities and
Exchange  Commission  (SEC)  that each Fund will  invest at least 90% of its net
assets in zero-coupon bonds until it is within four years of its target maturity
year and at least 80% of its net assets in zero-coupon securities while the Fund
is within two to four years of its target maturity year. This undertaking may be
revoked if the market supply of zero-coupon securities diminishes  unexpectedly,
although it will not be revoked without prior  consultation  with the SEC staff.
In addition,  the Manager has undertaken that any coupon-bearing  bond purchased
on behalf of a Fund will have a  duration  that falls  within the Fund's  target
maturity year.

     ANTICIPATED  GROWTH RATE. The Manager also calculates an anticipated growth
rate  (AGR)  for each Fund  each day the  Trust is open for  business.  AGR is a
calculation of the annualized  rate of growth an investor may expect from his or
her  purchase  date to the  Fund's  target  maturity  date.  As is the case with
calculations of AVM, the AGR calculation assumes that the investor will reinvest
all  dividends  and  capital  gain  distributions  (if any) and that the  Fund's
expense ratio and portfolio  composition will remain  constant.  Each Fund's AGR
changes from day to day primarily because of changes in interest rates and, to a
lesser extent, to changes in portfolio composition and other factors that affect
the value of the Fund's investments.

     The Manager expects that  shareholders who hold their shares until a Fund's
weighted  average  maturity date and who reinvest all dividends and capital gain
distributions  (if any),  will realize an investment  return and maturity  value
that do not differ  substantially from the AGR and AVM calculated on the day his
or her shares were purchased.

     The following  table  illustrates  investor  experience with Target 1990, a
series  of the Trust  that was first  offered  on March 25,  1985,  and that was
liquidated  on January  25,  1991.  This table is not  indicative  of the future
performance of the existing Funds.

     Calculations in the table above may not reconcile precisely due to rounding
of share price, AGR, and weighted average maturity to two decimal points.

     Note that the Target  1990's share price on December 31, 1990,  was not the
same as its AVM on that date  because the Fund had not yet been  liquidated  and
still held short-term Treasury  securities with a 25-day maturity.  The Fund was
liquidated on January 25, 1991, at a final share price of $101.46.

PERFORMANCE

     The Funds' yields and total returns may be quoted in advertising  and sales
literature.  These figures,  as well as the Funds' share prices will vary.  Past
performance should not be considered as indicative of future results.

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

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

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

     Each  Fund's  yield  for  the  30-day  period  ended  September  30,  1996,
calculated using the SEC yield formula described above, is indicated below.

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

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

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

     The Funds'  average  annual  total  returns  for the  one-year,  five-year,

     In addition to average annual total returns, each Fund may quote unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment over a stated period. Average annual and cumulative total returns may
be quoted as percentages or as dollar amounts and may be calculated for a single
investment,  a series of investments,  or a series of redemptions  over any time
period.  Total  returns may be broken down into their  components  of income and
capital  (including  capital gains and changes in share price) to illustrate the
relationship of these factors and their contributions to total return.

     The Funds' performance may be compared with the performance of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may include  comparisons with funds that, unlike the American
Century funds, are sold with a sales charge or deferred sales charge. Sources of
economic  data that may be used for such  comparisons  may include,  but are not
limited to, U.S. Treasury bill, note, and bond yields, money market fund yields,
U.S.  government debt and percentage held by foreigners,  the U.S. money supply,
net  free  reserves,  and  yields  on  current-coupon  GNMAs  (source:  Board of
Governors of the Federal Reserve  System);  the federal funds and discount rates
(source:  Federal  Reserve  Bank of New York);  yield  curves for U.S.  Treasury
securities and AA/AAA-rated  corporate  securities (source:  Bloomberg Financial
Markets);  yield curves for AAA-rated  tax-free  municipal  securities  (source:
Telerate);  yield curves for foreign government  securities (sources:  Bloomberg
Financial  Markets and Data  Resources,  Inc.);  total  returns on foreign bonds
(source:  J.P.  Morgan  Securities  Inc.);  various U.S. and foreign  government
reports;  the junk bond market (source:  Data Resources,  Inc.); the CRB Futures
Index  (source:  Commodity  Index Report);  the price of gold  (sources:  London
a.m./p.m.  fixing and New York Comex Spot Price); rankings of any mutual fund or
mutual fund category tracked by Lipper Analytical Services, Inc. or Morningstar,
Inc.;  mutual  fund  rankings   published  in  major,   nationally   distributed
periodicals;  data  provided  by  the  Investment  Company  Institute;  Ibbotson
Associates,  Stocks, Bonds, Bills, and Inflation;  major indexes of stock market
performance;  and  indexes and  historical  data  supplied  by major  securities
brokerage or investment advisory firms. The Funds may also utilize reprints from
newspapers  and magazines  furnished by third  parties to illustrate  historical
performances.

TAXES

     Each Fund intends to qualify annually as a "regulated  investment  company"
under  Subchapter  M of the  Internal  Revenue  Code of 1986,  as  amended  (the
"Code").  By so  qualifying,  a Fund will be exempt from federal and  California
income  taxes to the extent  that it  distributes  substantially  all of its net
investment income and net realized capital gains (if any) to shareholders.

     As holders of zero-coupon Treasury securities ("zeros"),  the Funds receive
no cash  payments  of  interest  prior to the  dates  these  securities  mature.
However,  portfolio  holdings  that  include  zeros  accrue  interest  (commonly
referred to as "imputed income") for federal income tax purposes.

     Under the Code,  dividends derived from interest,  imputed income,  and any
short-term  capital  gains are  federally  taxable to  shareholders  as ordinary
income,  regardless  of whether such  dividends  are taken in cash or reinvested
in additional shares. Distributions

Statement of Additional Information                                            7


designated as being made from a Fund's net realized  long-term capital gains are
taxable to shareholders as long-term capital gains,  regardless of the length of
time  shares  are  held.   Corporate   investors   are  not   eligible  for  the
dividends-received deduction with respect to distributions from the Funds.

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

     Dividends paid by each Fund are exempt from state personal  income taxes in
all states  because the Funds derive their  income from debt  securities  of the
U.S.  government whose interest payments are state tax-exempt.  Distributions of
capital gains are generally not exempt from state and local taxes.

     The information  above is only a summary of some of the tax  considerations
generally affecting the Funds and their  shareholders.  No attempt has been made
to discuss  individual tax consequences.  A prospective  investor should consult
with his or her tax  advisors  or state or local tax  authorities  to  determine
whether the Funds are suitable investments.

ABOUT THE TRUST

     American  Century Target  Maturities Trust (the "Trust") was organized as a
Massachusetts  business  trust on November  8, 1984.  The  Declaration  of Trust
permits  the  Board  of  Trustees  to  issue  an  unlimited  number  of full and
fractional shares of beneficial  interest without par value, which may be issued
in series (or Funds). Shares issued are fully paid and nonassessable and have no
preemptive, conversion, or similar rights.

     Currently,  there are six series of the Trust,  as  follows:  Target 2000 ,
Target 2005,  Target 2010,  Target 2015 , Target 2020 and Target 2025. The table
below  lists each  Fund's  current and former  name.  The Board of Trustees  may
create additional  series from time to time. In addition,  the Board of trustees
may liquidate a series at the conclusion of its target maturity year.

     Shares of each Fund have  equal  voting  rights,  although  each Fund votes
separately on matters affecting it exclusively. Voting rights are not cumulative
so that investors holding more than 50% of the Trust's outstanding shares may be
able to elect a Board of Trustees. The Trust has instituted dollar-based voting,
meaning  that the number of votes you are  entitled  to is based upon the dollar
amount of your  investment.  The election of Trustees is determined by the votes
received  from all Trust  shareholders  without  regard to whether a majority of
shares of any one series voted in favor of a particular  nominee or all nominees
as a group.

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

     Shareholders  of  a  Massachusetts  business  trust  could,  under  certain
circumstances,  be held  personally  liable for its  obligations.  However,  the
Declaration  of Trust contains an express  disclaimer of  shareholder  liability
for acts or obligations of the Trust. The

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

MANAGEMENT

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

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

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

Category Assets                                           Fee Rate

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

     The management  agreement shall continue in effect until the earlier of the
expiration  of two  years  from the date of its  execution  or until  the  first
meeting of  shareholders  following such execution and for as long thereafter as
its  continuance  is  specifically  approved at least annually by (1) the Funds'
Board of Trustees, or by the vote of a majority of outstanding votes (as defined
in the Investment Company Act) and (2) by the vote of a majority of the Trustees
of the 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 Trustees,  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,
trustees and employees may engage in other  business,  devote time and attention
to any other  business  whether of a similar or  dissimilar  nature,  and render
services to others.

     Certain  investments  may be  appropriate  for the 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 other  clients when the Manager  believes  that
such aggregation  provides the best execution for the Funds. The Funds' Board of
Trustees has approved the policy of the Manager with respect to the  aggregation
of portfolio  transactions.  Where portfolio  transactions have been aggregated,
the 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,  the Manager also acts as an  investment
advisor to 12 institutional  accounts and to the following registered investment
companies:  American Century Mutual Funds,  Inc.,  American Century World Mutual
Funds, Inc., American Century Premium Reserves,  Inc., American Century Variable
Portfolios, Inc., American Century

American Century  Municipal Trust,  American  Century  Government  Income Trust,
American Century  Investment  Trust,  American Century  California  Tax-Free and
Municipal Funds, American Century Quantitative Equity Funds and American Century
International Bond Funds.

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

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

     Share purchases and redemptions are governed by California law.

     FUND  LIQUIDATIONS.  On or  before  January  31st of the year  following  a
Fund's target maturity year, its investments  will be sold or allowed to mature;
its liabilities will be discharged, or a provision will be made

14                                                  American Century Investments


for their  discharge,  and its accounts will be closed. A shareholder may choose
to redeem  his or her  shares in one of the  following  ways:  (i) by  receiving
redemption  proceeds or (ii) by exchanging shares for shares of another American
Century fund. If the Fund receives no  instructions  from a shareholder,  his or
her shares  will be  exchanged  for shares of  Capital  Preservation  Fund (or a
similar  fund if Capital  Preservation  Fund is not  available).  The  estimated
expenses of terminating  and liquidating a Fund will be accrued ratably over its
target maturity year.  These  expenses,  which are charged to income (as are all
expenses), are not expected to exceed significantly the ordinary annual expenses
incurred  by a Fund  and,  therefore,  should  have  little  or no effect on the
maturity value of the Fund.

SPECIAL MEETING OF SHAREHOLDERS

At a Special Meeting of Shareholders held on July 30, 1997,  shareholders of the
Fund approved,  among other things, a new Management  Agreement between the Fund
with American Century Investment Management,  Inc. This new Management Agreement
will  become  effective  on August 1, 1997,  and  replaces  the  Fund's  current
investment advisory agreement with Benham Management  Corporation,  an affiliate
of American Century Investment Management, Inc.

At the meeting,  shareholders of the Fund also ratified the selection of Coopers
& Lybrand LLP as the  independent  auditors for the Fund's  current fiscal year,
approved  the adoption of  standardized  investment  limitations  by amending or
eliminating certain of the Fund's fundamental investment limitations, approved a
new  Subadvisory  Agreement with J.P.  Morgan  Investment  Management,  Inc. and
approved of  amendments  to the Fund's  fundamental  investment  objective.  The
changes resulting from the Special Meeting of Shareholders are reflected in this
Prospectus Supplement and in the revised Statement of Additional  Information of
the Fund.

INVESTMENT OBJECTIVE

On page 2,  after the  sentence  under  the  caption  "American  Century--Benham
European Government Bond Fund," the following paragraph is added:

     Effective October 1, 1997, the investment  objective of the Fund will be to
seek to provide high  current  income and capital  appreciation  by investing in
high-quality,  nondollar-denominated  government and corporate  debt  securities
outside the U.S. Effective October 1, 1997, the name of the Fund will be changed
to  "American  Century--Benham  International  Bond Fund."  These  changes  were
approved by shareholders at the July 30, 1997, Special Meeting.

INVESTMENT OBJECTIVE OF THE FUND

On page 2, in the section  "American  Century--Benham  European  Government Bond
Fund" and on page 6, in the  subsection  "Investment  Objective,"  the following
additional paragraph is added:

     On October 1, 1997, the Fund's investment  objective will change.  The Fund
will seek to provide high current income and capital  appreciation  by investing
in high-quality,  nondollar-denominated government and corporate debt securities
outside the U.S. (the "New Investment Objective"). The Fund will also change its
name to  "American  Century--Benham  International  Bond Fund" to  reflect  this
change.  This change was approved by  shareholders at a meeting held on July 30,
1997. The pending change will change the risk  characteristics  of an investment
in the Fund. You are encouraged to read this Prospectus Supplement carefully.

CURRENCY MANAGEMENT

On page 7, in the  carryover  subsection  "Currency  Management,"  the following
paragraph is added:

     The currency  management  techniques  employed by JPMIM will continue under
the New  Investment  Objective.  Because  the  Fund  will  be  able to  purchase
securities  of  issuers  outside  Europe,  the  currency  management  techniques
described  above may be  utilized  to hedge with  respect to  currencies  of any
country in which the Fund may invest.

INVESTMENT TECHNIQUES UNDER
THE NEW INVESTMENT OBJECTIVE

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

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

ISSUER DIVERSIFICATION

On page 8, in the carryover subsection "Issuer  Diversification,"  the following
paragraph is added:

     Under the New  Investment  Objective,  the Fund is not expected to maintain
its investment in securities  issued by the German government in amounts greater
than 25% of the  Fund's  total  assets.  In  addition,  the Fund may  invest  in
corporate debt securities rated "AA" or better. See "Investment Techniques Under
the New Investment Objective," above.

CREDIT QUALITY

On page 8, in the subsection "Credit Quality," the following paragraph is added:

     Under the New  Investment  Objective,  the Fund will invest  exclusively in
high quality  instruments  of the types  described  above.  "High  quality" debt
securities  are  those  rated  in the  top two  ratings  categories  of  Moody's
Investors Service, Inc. ("Moody's"),  Standard & Poor's Ratings Services ("S&P")
or Fitch Investors Service, Inc. ("Fitch") or, if not rated, determined to be of
comparable  quality by JPMIM.  This necessarily  means that the Fund will not be
able to  invest  in  securities  issued by many  countries  (including  those of
corporations based in these countries) whose credit ratings do not satisfy these
requirements.  See the Appendix  for further  information  about the  securities
ratings.

FOREIGN SECURITIES

On page 8, in the section "Other Investment Practices, Their Characteristics and
Risks," the following new subsection is added before the subsection "When-Issued
and Forward Commitment Agreements":

     Broad international  investing involves additional risks which can increase
the potential  for losses in the Fund under the New  Investment  Objective  when
compared to the Fund's current  investments in European  government  securities.
The currency risk associated with international  investing may be more difficult
to eliminate  entirely and the likelihood that hedging will work may be reduced.
In  addition,  it may not be possible to  effectively  hedge the  currencies  of
certain non-European  countries.  Furthermore,  hedging costs may be higher than
under the Fund's current investment objective, and these costs are paid out of a
Fund's  capital and  reflected in the net asset value.  Although  expanding  the
universe of potential Fund investments to include  countries  outside Europe may
increase these risks, the high quality credit standards  adopted by the Trustees
is designed to help minimize the magnitude of the risks.

     o   Costs. Some foreign markets may be more expensive for U.S. investors to
         trade in than those in Europe and certainly  more  expensive than those
         markets  in the U.S.  As a  consequence,  the Fund could  incur  higher
         transaction costs for its investments in these markets.

     o   Political and economic factors.  The economies,  markets, and political
         structures  of a number of the  countries  in which the Fund can invest
         may not  compare  favorably  with those of the  European  countries  in
         which the Fund can currently  invest in terms of wealth and  stability.
         Therefore,  investments in these  countries will be riskier and subject
         to  more   erratic   and  abrupt   price   movements.   While  this  is
         particularly  true for  emerging  markets of the type in which the Fund
         cannot invest,  even  investments  in countries  with highly  developed
         economies are subject to risk.

     o   Location of Company.  In  determining  the domicile or nationality of a
         company,  the Fund will primarily consider the following  factors:  (1)
         whether  the  securities  of the  company  are  primarily  traded  in a
         particular  country;  (2) whether the company has its  principal  place
         of business or principal  office in or is  organized  under the laws of
         a  particular  country;   and  (3)  regardless  of  where  a  company's
         securities  are  traded,  whether it derives a  significant  proportion
         (at least 50%) of its  revenues  or  profits  from  goods  produced  or
         sold,  investments  made,  or services  performed in the country or has
         at least 50% of its assets situated in that country.

SECURITIES LENDING

On page 9, in the  subsection  "Securities  Lending,"  the last  sentence of the
paragraph is deleted and the following new paragraph is added:

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

INVESTMENT MANAGEMENT

On page 19, the first two paragraphs in the subsection  "Investment  Management"
are deleted and replaced with the following:

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

On page 20, the three full  paragraphs  before the  subsection  heading "Code of
Ethics" are deleted and replaced with the following:

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

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

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

     For the services  provided to the Fund, the Manager  receives a monthly fee
based on a percentage of the average net assets of the Fund.  The annual rate at
which this fee is assessed is determined monthly in a two-step process: First, a
fee rate  schedule is applied to the assets of all of the bond funds  managed by
the  Manager  (the  "Investment  Category  Fee").  Second,  a separate  fee rate
schedule  is applied to the  assets of all of the  mutual  funds  managed by the
Manager (the "Complex Fee"). The Investment Category Fee and the Complex Fee are
then added to determine  the unified  management  fee payable by the Fund to the
Manager.  Currently,  the Investment Category Fee for the Fund is an annual rate
of 0.55% of the average net assets of the Fund.  The Complex Fee is currently an
annual rate of 0.30% of the average net assets of the Fund. Further  information
about the calculation of the annual management fee is contained in the Statement
of Additional Information.

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

TRANSFER AND ADMINISTRATIVE SERVICES

On page 20, the first paragraph under the heading  "Transfer and  Administrative
Services" is deleted and replaced with the following:

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

EXPENSES

On page 21, the subsection called "Expenses" is deleted.

INVESTMENT POLICIES, TECHNIQUES AND RISK FACTORS

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

CHANGE IN INVESTMENT OBJECTIVE

     On July 30, 1997,  shareholders  of the Fund  approved a proposal to change
the Fund's investment objective. This change will become effective on October 1,
1997.  As a result of the change,  the name of the Fund will change to "American
Century--Benham International Bond Fund". More significantly, the Fund will face
additional risks  associated from its investment in countries  outside of Europe
and from its increased investment in corporate debt securities.

EUROPEAN GOVERNMENT BONDS

     The Fund invests  primarily in European  government  bonds.  The market for
these bonds is active; however, there are risks associated with investing in the
European  government bond market  distinct from those typically  associated with
investing in U.S. government bonds. The following is a brief list of the primary
risks you should consider.

     1. CURRENCY EXCHANGE RATE  RISK--Currencies in which the Fund's investments
are denominated may decline significantly relative to the U.S. dollar.

     2. TAX RISK--Interest income from European government bonds may be taxed by
foreign  governments  at  significantly  higher rates than interest  income from
domestic  investments.  As has  happened  in the past,  the U.S.  government  or
European governments may adopt tax policies that discourage overseas investing.

     3. SETTLEMENT  RISK--J.P.  Morgan Investment  Management,  Inc. (JPMIM) may
encounter  difficulties  resulting  from  delays in settling  transactions  with
European  broker-dealers.  Settlement delays may encumber  portfolio  management
efforts  by  tying  up  Fund  assets  at  times  when  JPMIM  perceives   market
opportunities.

     Under  normal  conditions,  more than 25% of the  Fund's  total  assets are
invested  in  securities  issued  by the  German  government  or  its  political
subdivisions.  This policy is currently  viewed by the  Securities  and Exchange
Commission  (SEC)  staff as a  concentration  policy.  Under  Section  13 of the
Investment  Company Act of 1940 (the  "Investment  Company Act"), a Fund may not
change its concentration policy without shareholder approval.

EUROPEAN CORPORATE BONDS

     If necessary to satisfy diversification  requirements under Subchapter M of
the  Internal  Revenue Code (the  "Code"),  the Fund may invest a portion of its
assets in AAA-rated European corporate bonds. The risks of investing in European
corporate bonds are somewhat greater than the risks associated with investing in
European  government bonds. In addition to the risks outlined above with respect
to European government bonds, JPMIM may encounter  difficulty obtaining adequate
public  information  about corporate bond issuers.  Investment  decisions may be
encumbered  by the lack of uniform  accounting,  audit,  or financial  reporting
standards  among  European  issuers or nations.  The Fund may encounter  greater
volatility and less liquidity in foreign corporate bond markets than it would in
U.S.  bond  markets and less  government  regulation  of foreign  exchanges  and
broker-dealers than is typical in the United States.

     The Fund's European  investments  (government or corporate) may be affected
by political  or economic  developments  within or among  European  nations,  or
between European nations and the United States.

U.S. GOVERNMENT SECURITIES

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

     Some U.S. government  securities are supported by the direct full faith and
credit pledge of the U.S.  government;  others are supported by the right of the
issuer to borrow from the U.S.  Treasury;  others,  such as securities issued by
the  Federal  National  Mortgage   Association  (FNMA),  are  supported  by  the
discretionary  authority  of the  U.S.  government  to  purchase  the  agencies'
obligations;  and others  are  supported  only by the  credit of the  issuing or
guaranteeing

2                                                   American Century Investments


instrumentality.  There is no assurance  that the U.S.  government  will provide
financial  support to an  instrumentality  it sponsors  when it is not obligated
by law to do so.

REPURCHASE AGREEMENTS

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

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

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

     Under the  Investment  Company Act,  repurchase  agreements  are considered
loans.

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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

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

     In purchasing  securities on a when-issued or forward commitment basis, the
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash or appropriate  liquid assets including equity securities and
debt securities of any grade in an amount sufficient to meet the purchase price.
When the time comes to pay for the  when-issued  securities,  the Fund will meet
its  obligations  with  available  cash,  through  the sale of  securities,  or,
although  it would not  normally  expect to do so, by  selling  the  when-issued
securities  themselves  (which may have a market value  greater or less than the
Fund's payment  obligation).  Selling  securities to meet when-issued or forward
commitment obligations may generate taxable capital gains or losses.

SECURITIES LENDING

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

     To minimize the risk of default on securities loans, the Manager adheres to
guidelines  prescribed by the Board of Trustees governing lending of securities.
These guidelines strictly govern (1) the type and amount of collateral that must
be received by the Fund;  (2) the  circumstances  under which  additions to that
collateral must be made by borrowers; (3) the

Statement of Additional Information                                            3


return received by the Fund on the loaned securities; (4) the limitations on the
percentage  of Fund  assets on loan;  and (5) the  credit  standards  applied in
evaluating  potential  borrowers  of  portfolio  securities.  In  addition,  the
guidelines  require  that the Fund have the  option to  terminate  any loan of a
portfolio  security at any time and set  requirements for recovery of securities
from borrowers.

FOREIGN CURRENCY EXCHANGE TRANSACTIONS

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

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

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

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

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

     In addition,  the Fund may combine  forward  transactions in its underlying
currency with investments in U.S. dollar-denominated  instruments, in an attempt
to construct an investment position whose overall performance will be similar to
that of a security  denominated  in its  underlying  currency.  If the amount of
dollars to be exchanged is properly  matched with the  anticipated  value of the
dollar-denominated securities, the Fund should be able to

4                                                   American Century Investments


"lock in" the foreign  currency value of the securities,  and the Fund`s overall
investment  return from the  combined  position  should be similar to the return
from  purchasing a foreign  currency-denominated  instrument.  This is sometimes
referred to as a "synthetic" investment position or a "position hedge."

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

FUTURES AND OPTIONS TRANSACTIONS

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

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

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

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

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

     Although  techniques  other than trading  futures  contracts can be used to
control the Fund's exposure to market fluctuations, the use of futures contracts
may be a more  effective  means of hedging  this  exposure.  While the Fund pays
brokerage  commissions  in  connection  with  opening  and  closing  out futures
positions,  these  costs are lower than the  transaction  costs  incurred in the
purchase and sale of the underlying securities.

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

Statement of Additional Information                                            5


of the underlying  instrument at the strike price. The Fund may also terminate a
put option  position  by closing it out in the  secondary  market at its current
price if a liquid secondary market exists.

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

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

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

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

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

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

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

6                                                   American Century Investments


because these options  generally can be closed out only by negotiation  with the
other party to the option.

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

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

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

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

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

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

     LIQUIDITY OF FUTURES  CONTRACTS AND OPTIONS.  There is no assurance  that a
liquid secondary market will exist for any particular futures contract or option
at any  particular  time.  Options may have  relatively  low trading  volume and
liquidity if their strike  prices are not close to the  underlying  instrument's
current  price.  In addition,  exchanges may establish  daily price  fluctuation
limits for futures  contracts  and options and may halt  trading if a contract's
price moves  upward or downward  more than the limit on a given day. On volatile
trading  days when the price  fluctuation  limit is reached or a trading halt is
imposed,  it may be impossible for the Fund to enter into new positions or close
out existing  positions.  If the secondary market for a contract was not liquid,
because  of  price  fluctuation  limits  or  otherwise,  prompt  liquidation  of
unfavorable  positions  could be difficult or impossible,  and the Fund could be
required to continue holding a position until delivery or expiration  regardless
of changes in its value. Under

Statement of Additional Information                                            7


these  circumstances,  the  Fund's  access  to assets  held to cover its  future
positions could also be impaired.

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

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

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

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

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

INVESTMENT RESTRICTIONS

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

     AS A FUNDAMENTAL POLICY, THE FUND SHALL NOT:

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

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

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

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

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

     6)  act as an  underwriter  of securities  issued by others,  except to the
extent that the Fund may

8                                                   American Century Investments


be considered an underwriter within the meaning of the Securities Act of 1933 in
the disposition of restricted securities.

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

     8)  invest for purposes of exercising control over management.

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

     AS AN OPERATING POLICY, THE FUND:

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

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

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

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

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

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

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

PORTFOLIO TRANSACTIONS

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

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

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

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

TRANSACTIONS WITH JPMIM AFFILIATES

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

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

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

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

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

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

     The Fund will not purchase securities directly from Morgan affiliates,  and
the size of Morgan  affiliates'  holdings  may limit the  selection of available
securities in a particular  maturity,  yield, or price range.  The Fund will not
execute any transactions  with Morgan  affiliates and will use only unaffiliated
broker-dealers.  In addition,  the Fund will not purchase any securities of U.S.
government  agencies during the existence of an underwriting or selling group of
which a Morgan affiliate is a member, except to the extent permitted by law.

     The Fund's  ability to engage in  transactions  with Morgan  affiliates  is
restricted by the SEC and the Federal Reserve Board. In JPMIM's  opinion,  these
limitations should not significantly impair the Fund's

10                                                  American Century Investments


ability to pursue its investment objectives. However, there may be circumstances
in which the Fund is disadvantaged by these limitations  compared to other funds
with similar investment objectives that are not subject to these limitations.

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

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

VALUATION OF PORTFOLIO SECURITIES

     The Fund's net asset value per share  ("NAV") is calculated as of the close
of business of the New York Stock Exchange (the "Exchange") usually at 3:00 p.m.
Central  time each day the  Exchange  is open for  business.  The  Exchange  has
designated the following  holiday  closings for 1997: New Year's Day (observed),
Martin  Luther  King Jr.  Day,  Presidents`  Day,  Good  Friday,  Memorial  Day,
Independence  Day, Labor Day,  Thanksgiving  Day, and Christmas Day  (observed).
Although  the Fund  expects  the same  holiday  schedule  to be  observed in the
future, the Exchange may modify its holiday schedule at any time.

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

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

PERFORMANCE

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

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

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

Statement of Additional Information                                           11


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

     For the 30-day period ended December 31, 1996, the Fund's yield was 5.07%.

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

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

     In addition to average annual total returns,  the Fund may quote unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment over a stated period. Average annual and cumulative total returns may
be quoted as a  percentage  or as a dollar  amount and may be  calculated  for a
single investment, a series of investments,  or a series of redemptions over any
time period.  Total  returns may be broken down into their  components of income
and capital  (including  capital gains and changes in share price) to illustrate
the relationship of these factors and their  contributions to total return.  The
Fund's one year, three year and life of fund average annual total return through
December 31, 1996, are indicated in the following table:

                                      Average Annual Total Return
- -----------------------------------------------------------------------------
One Year                                        6.38%
Three Year                                     10.34%
Life of Fund                                   10.48%

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

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

from  newspapers  and  magazines   furnished  by  third  parties  to  illustrate
historical performance.

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

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

TAXES

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

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

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

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

     Earnings  derived by the Fund from sources  outside the U.S. may be subject
to non-U.S.  withholding and possibly other taxes.  Such taxes may be reduced or
eliminated under the terms of a U.S. income tax treaty,  and the Fund intends to
undertake any procedural  steps required to claim the benefits of such a treaty.
With respect to any non-U.S.  taxes  actually paid by the Fund, if more than 50%
in value of the Fund's total assets at the close of any taxable year consists of
securities  of foreign  corporations,  the Fund will elect to treat any non-U.S.
income  and  similar  taxes  it  pays  as  though  the  taxes  were  paid by its
shareholders.

Statement of Additional Information                                           13


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

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

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

TAXATION OF U.S. SHAREHOLDERS

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

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

TAXATION OF NON-U.S. SHAREHOLDERS

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

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

     If the  shareholder  is not  engaged in a U.S.  trade or  business,  or the
payments  received from the Fund are not effectively  connected with the conduct
of such a trade or business,  the shareholder  will generally be subject to U.S.
tax  withholding  at the rate of 30% (or a lower rate under an  applicable  U.S.
income tax treaty) on  distributions  of net investment  income and net realized
short-term capital received.  Non-U.S.  shareholders not engaged in a U.S. trade
or business,  or having no effectively  connected income, may also be subject to
U.S.  tax  at  the  rate  of  30%  (or  a  lower  treaty  rate)  on   additional
distributions  resulting  from the Fund's  election to treat any non-U.S.  taxes
it pays as though the taxes were paid by its shareholders.

     Distributions  of  net  realized   long-term   capital  gains  to  non-U.S.
shareholders  and any  capital  gains  realized by them upon the  redemption  or
other

14                                                  American Century Investments


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

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

ABOUT THE TRUST

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

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

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

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

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

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

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

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

received for the Fund's  fiscal year ended  December  31,  1996,  as well as the

MANAGEMENT

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

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

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

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

     The Complex Fee Schedule is as follows:

Statement of Additional Information                                           17


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

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

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

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

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

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

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

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

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

     For the fiscal years ended December 31, 1996, 1995, and 1994, the Fund paid
investment advisory fees as listed in the table on page 19.

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

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

     The  subadvisory   agreement  provides  that  JPMIM  will  make  investment
decisions  for the Fund in  accordance  with the  Fund's  investment  objective,
policies,  and restrictions,  and whatever  additional written guidelines it may
receive from the Manager from time to time. For these services, the Manager pays
JPMIM a monthly  fee at an annual rate of .20% of the Fund's  average  daily net
assets  up to $200  million;  and .15% of  average  daily net  assets  over $200
million. Under the 1991 subadvisory agreement,  the Manager paid JPMIM a monthly
fee at an annual  rate of .25% of average  daily net assets up to $200  million,
and .05% of average daily net assets in excess of $200  million,  with a minimum
annual fee of $250,000.

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

SECURITIES RATINGS

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

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

     Aaa: Bonds that are rated "Aaa" are judged to be of the best quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
"gilt edge." Interest payments are protected by a large or exceptionally  stable
margin,  and  principal  is secure.  While the various  protective  elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

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

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

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

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

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

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

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

     C:  Bonds  that are rated  "C" are the  lowest-rated  class of  bonds,  and
issues so rated can be regarded as

20                                                  American Century Investments


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

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

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

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

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

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

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

     Moody's  commercial paper ratings are opinions of the ability of issuers to
punctually repay those promissory obligations that have an original maturity not
exceeding nine months. Moody's makes no representation that such obligations are
exempt from registration under the Securities Act of 1933, nor does it represent
that any  specific  note is a valid  obligation  of a rated  issuer or issued in
conformity with any applicable law. The following designations, all judged to be
investment  grade,  indicate the relative  repayment ability of rated issuers of
securities in which the Funds may invest.

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

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

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

INVESTMENT GRADE

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

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

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

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

SPECULATIVE

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

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

Statement of Additional Information                                           21


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

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

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

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

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

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

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

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

     SP-1:  Issues  carrying  this  designation  have a very  strong  or  strong
capacity to pay  principal  and  interest.  Those issues  determined  to possess
overwhelming safety characteristics will be given a plus (+) designation.

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

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

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

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

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

INVESTMENT POLICIES AND TECHNIQUES

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

U.S. GOVERNMENT SECURITIES

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

REPURCHASE AGREEMENTS

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

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

    The Fund has received permission from the Securities and Exchange Commission
("SEC") to participate in joint  repurchase  agreements  collateralized  by U.S.
government  securities  with other mutual funds  advised by the Fund's  Manager.
Joint  repos are  expected  to  increase  the income the Fund can earn from repo
transactions without increasing the risks associated with these transactions.

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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


2                                             AMERICAN CENTURY INVESTMENTS


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

    In purchasing  securities on a when-issued or forward  commitment basis, the
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash or appropriate  liquid assets including equity securities and
debt securities of any grade in an amount sufficient to meet the purchase price.
When the time comes to pay for  when-issued  securities,  the Fund will meet its
obligations with available cash, through the sale of securities, or, although it
would not normally expect to do so, through sales of the when-issued  securities
themselves  (which  may have a market  value  greater  or less  than the  Fund's
payment   obligation).   Selling  securities  to  meet  when-issued  or  forward
commitment obligations may generate taxable gains or losses.

    These types of transactions are executed simultaneously in what are known as
"dollar-roll" or "cash-and-carry" transactions. For example, a broker-dealer may
seek to purchase a particular  security  that the Fund owns.  The Fund will sell
that  security  to the  broker-dealer  and  simultaneously  enter into a forward
commitment  agreement to buy it back at a future date.  This type of transaction
generates  income  for  the  Fund  if the  dealer  is  willing  to  execute  the
transaction at a favorable price in order to acquire a specific security.

    As an operating policy,  the Fund will not commit more than 35% of its total
assets to when-issued or forward commitment  agreements.  If fluctuations in the
value of  securities  held cause more than 35% of the Fund's  total assets to be
committed under when-issued or forward commitment  agreements,  the Manager need
not sell such  commitment,  but it will be restricted from entering into further
agreements  on behalf of the Fund until the  percentage  of assets  committed to
such agreements is reduced to 35%. In addition, as an operating policy, the Fund
will  not  enter  into  when-issued  or  forward  commitment  transactions  with
settlement dates exceeding 120 days.

MORTGAGE-BACKED SECURITIES

    GENERAL.  A mortgage-backed  security  represents an ownership interest in a
pool of mortgage loans. The loans are made by financial  institutions to finance
home and other real estate purchases. As the loans are repaid, investors receive
payments of both interest and principal.

    Like fixed-income securities,  such as U.S. Treasury bonds,  mortgage-backed
securities pay a stated rate of interest over the life of the security. However,
unlike  a bond,  which  returns  principal  to the  investor  in one lump sum at
maturity,  mortgage-backed  securities  return  principal  to  the  investor  in
increments over the life of the security.

    Because the timing and speed of principal  repayments vary, the cash flow on
mortgage  securities  is  irregular.  If  mortgage  holders  sell  their  homes,
refinance their loans,  prepay their  mortgages,  or default on their loans, the
principal is distributed pro rata to investors.

    As with other  fixed-income  securities,  the prices of mortgage  securities
fluctuate in response to changing  interest rates; when interest rates fall, the
prices of mortgage securities rise, and vice versa. Changing interest rates have
additional  significance  for  mortgage-backed  securities  investors,  however,
because they influence  prepayment  rates (the rates at which  mortgage  holders
prepay  their  mortgages),  which in turn  affect the yields on  mortgage-backed
securities.  When interest rates decline,  prepayment rates generally  increase.
Mortgage  holders take advantage of the opportunity to refinance their mortgages
at lower rates with lower monthly payments.  When interest rates rise,  mortgage
holders are less inclined to refinance their mortgages. The effect of prepayment
activity on yield depends on whether the mortgage-backed  security was purchased
at a premium or at a discount.

    The  Fund  may get  back  principal  sooner  than  it  expected  because  of
accelerated  prepayments.  Under  these  circumstances,  the Fund  might have to
reinvest  returned  principal  at rates  lower  than it  would  have  earned  if
principal payments were made on schedule. Conversely, a mortgage-backed security
may exceed


STATEMENT OF ADDITIONAL INFORMATION                                       3


its anticipated life if prepayment rates  decelerate  unexpectedly.  Under these
circumstances,  the Fund might miss an  opportunity  to earn  interest at higher
prevailing rates.

    GINNIE MAE CERTIFICATES.  The Government  National  Mortgage  Association ("
GNMA" or "Ginnie Mae") is a wholly owned corporate instrumentality of the United
States  within the  Department  of Housing and Urban  Development.  The National
Housing  Act of 1934  ("Housing  Act"),  as  amended,  authorizes  Ginnie Mae to
guarantee  the  timely  payment  of  interest  and  repayment  of  principal  on
certificates  that are backed by a pool of mortgage loans insured by the Federal
Housing  Administration  under the Housing Act, or by Title V of the Housing Act
of 1949 (FHA Loans),  or guaranteed by the  Veterans'  Administration  under the
Servicemen's  Readjustment  Act of 1944 (VA Loans),  as amended,  or by pools of
other eligible  mortgage loans. The Housing Act provides that the full faith and
credit of the U.S.  government is pledged to the payment of all amounts that may
be required to be paid under any guarantee.  Ginnie Mae has unlimited  authority
to borrow  from the U.S.  Treasury in order to meet its  obligations  under this
guarantee.

    Ginnie Mae  certificates  represent a pro rata interest in one or more pools
of the following types of mortgage loans:  (i) fixed-rate level payment mortgage
loans;  (ii)  fixed-rate  graduated  payment  mortgage  loans  ("GPM"s);   (iii)
fixed-rate  growing equity  mortgage loans ("GEM"s);  (iv)  fixed-rate  mortgage
loans secured by  manufactured  (mobile)  homes  ("MH"s);  (v) mortgage loans on
multifamily  residential properties under construction  ("CLC"s);  (vi) mortgage
loans on completed  multifamily  projects  ("PLC"s);  (vii) fixed-rate  mortgage
loans that use escrowed funds to reduce the borrower's  monthly  payments during
the early years of the  mortgage  loans  (buydown  mortgage  loans);  and (viii)
mortgage loans that provide for payment adjustments based on periodic changes in
interest rates or in other payment terms of the mortgage loans.

    FANNIE MAE CERTIFICATES.  The Federal National Mortgage  Association ("FNMA"
or "Fannie  Mae") is a  federally  chartered  and  privately  owned  corporation
organized and existing under the Federal National Mortgage  Association  Charter
Act. Fannie Mae was originally  established in 1938 as a U.S.  government agency
to provide supplemental  liquidity to the mortgage market and was reorganized as
a stockholder-owned  and privately managed corporation by legislation enacted in
1968. Fannie Mae acquires capital from investors who would not ordinarily invest
in  mortgage  loans  directly  and  thereby  expands  the total  amount of funds
available for housing.  This money is used to buy home mortgage loans from local
lenders,  which  replenishes  the  supply of  capital  for  additional  mortgage
lending.

    Fannie Mae  certificates  represent a pro rata interest in one or more pools
of FHA Loans, VA Loans,  or, most commonly,  conventional  mortgage loans (i.e.,
mortgage loans that are not insured or guaranteed by a  governmental  agency) of
the  following  types:  (i)  fixed-rate  level  payment  mortgage  loans;   (ii)
fixed-rate  growing equity mortgage loans;  (iii)  fixed-rate  graduated-payment
mortgage loans; (iv) adjustable-rate mortgage loans; and (v) fixed-rate mortgage
loans secured by multifamily projects.

    Fannie Mae  certificates  entitle the registered  holder to receive  amounts
representing  a pro rata interest in scheduled  principal and interest  payments
(at the  certificate's  pass-through  rate,  which is net of any  servicing  and
guarantee fees on the underlying mortgage loans), any principal prepayments, and
a  proportionate  interest in the full  principal  amount of any  foreclosed  or
otherwise  liquidated mortgage loan. The full and timely payment of interest and
repayment of principal on each Fannie Mae  certificate  is  guaranteed by Fannie
Mae;  this  guarantee  is not  backed by the full  faith and  credit of the U.S.
government.

    FREDDIE MAC  CERTIFICATES.  The Federal Home Loan  Mortgage  Corporation  ("
FHLMC" or "Freddie  Mac") is a corporate  instrumentality  of the United  States
created  pursuant to the Emergency  Home Finance Act of 1970 ("FHLMC  Act"),  as
amended. Freddie Mac was established primarily for the purpose of increasing the
availability of mortgage credit.  Its principal  activity consists of purchasing
first-lien  conventional  residential mortgage loans (and participation interest
in such mortgage loans) and reselling these loans in the form of mortgage-backed
securities, primarily Freddie Mac certificates.

    Freddie  Mac  certificates  represent  a pro  rata  interest  in a group  of
mortgage loans (a Freddie Mac certificate  group)  purchased by Freddie Mac. The
mortgage loans underlying Freddie Mac certificates


4                                             AMERICAN CENTURY INVESTMENTS


consist  of fixed- or  adjustable-rate  mortgage  loans with  original  terms to
maturity  of 10 to 30 years,  substantially  all of which are  secured  by first
liens on one- to four-family  residential  properties or  multifamily  projects.
Each mortgage loan must meet standards set forth in the FHLMC Act. A Freddie Mac
certificate  group may include  whole  loans,  participation  interests in whole
loans,  undivided  interests in whole  loans,  and  participations  constituting
another Freddie Mac certificate group.

    Freddie  Mac  guarantees  to  each  registered   holder  of  a  Freddie  Mac
certificate  the timely  payment of  interest  at the rate  provided  for by the
certificate. Freddie Mac also guarantees ultimate collection of all principal on
the related mortgage loans, without any offset or deduction,  but generally does
not guarantee the timely repayment of principal. Freddie Mac may remit principal
at any time after default on any underlying  mortgage loan, but no later than 30
days following:  (i)  foreclosure  sale, (ii) payment of a claim by any mortgage
insurer,  or (iii) the expiration of any right of redemption,  whichever  occurs
later,  and in any event no later than one year after  demand has been made upon
the mortgager for accelerated  payment of principal.  Obligations  guaranteed by
Freddie Mac are not backed by the full faith and credit of the U.S. government.

    COLLATERALIZED  MORTGAGE  OBLIGATIONS  ("CMO"S).  A CMO is a multiclass bond
backed by a pool of mortgage  pass-through  certificates or mortgage loans. CMOs
may be collateralized by (i) Ginnie Mae, Fannie Mae, or Freddie Mac pass-through
certificates,  (ii) unsecuritized  mortgage loans insured by the Federal Housing
Administration  or guaranteed  by the  Department  of Veterans'  Affairs,  (iii)
unsecuritized conventional mortgages, or (iv) any combination thereof.

    In  structuring a CMO, an issuer  distributes  cash flow from the underlying
collateral over a series of classes called  "tranches." Each CMO is a set of two
or more  tranches  with average  lives and cash flow  patterns  designed to meet
specific investment  objectives.  The average life expectancies of the different
tranches in a four-part  deal, for example,  might be two, five,  seven,  and 20
years.

    As payments on the underlying  mortgage loans are collected,  the CMO issuer
pays the coupon rate of  interest to the  bondholders  in each  tranche.  At the
outset,  scheduled  and  unscheduled  principal  payments go to investors in the
first  tranches.  Investors in later tranches do not begin  receiving  principal
payments  until the prior tranches are paid off. This basic type of CMO is known
as a "sequential pay" or "plain vanilla" CMO.

    Some  CMOs are  structured  so that  the  prepayment  or  market  risks  are
transferred  from one tranche to another.  Prepayment  stability  is improved in
some tranches if other tranches absorb more prepayment variability.

    The final  tranches of a CMO often take the form of a Z-bond,  also known as
an "accrual bond" or "accretion  bond." Holders of these  securities  receive no
cash until the  earlier  tranches  are paid in full.  During the period that the
other  tranches are  outstanding,  periodic  interest  payments are added to the
initial face amount of the Z-bond but are not paid to investors.  When the prior
tranches  are  retired,  the  Z-bond  receives  coupon  payments  on its  higher
principal balance,  plus any principal  prepayments from the underlying mortgage
loans.  The existence of a Z-bond tranche helps  stabilize cash flow patterns in
the other tranches. In a changing interest rate environment,  however, the value
of the Z-bond tends to be more volatile.

    As CMOs have evolved,  some classes of CMO bonds have become more prevalent.
The planned amortization class ("PAC") and targeted  amortization class ("TAC"),
for  example,  were  designed  to  reduce  prepayment  risk  by  establishing  a
sinking-fund  structure.  PAC and TAC  bonds  assure  to  varying  degrees  that
investors  will receive  payments  over a  predetermined  period  under  various
prepayment  scenarios.  Although  PAC and TAC bonds are  similar,  PAC bonds are
better able to provide stable cash flows under various prepayment scenarios than
TAC bonds because of the order in which these tranches are paid.

    The  existence of a PAC or TAC tranche can create  higher levels of risk for
other  tranches in the CMO because  the  stability  of the PAC or TAC tranche is
achieved  by  creating at least one other  tranche  known as a  companion  bond,
support,  or non-PAC bond that absorbs the  variability of principal cash flows.
Because  companion  bonds have a high degree of average life  variability,  they
generally  pay a  higher  yield.  A TAC bond  can  have  some of the  prepayment
variability of a companion bond if there is also a PAC bond in the CMO issue.


STATEMENT OF ADDITIONAL INFORMATION                                      5


    Floating-rate CMO tranches ("floaters") pay a variable rate of interest that
is usually tied to the London  Interbank  Offered Rate ("LIBOR").  Institutional
investors with  short-term  liabilities,  such as commercial  banks,  often find
floating-rate  CMOs  attractive  investments.  "Super  floaters"  (which float a
certain percentage above LIBOR) and "inverse floaters" (which float inversely to
LIBOR) are variations on the floater structure with highly variable cash flows.

CONVERTIBLE SECURITIES

    The Fund may buy securities that are convertible  into common stock.  Listed
below are brief descriptions of the various types of convertible  securities the
Fund may buy.

    Convertible bonds are issued with lower coupons than nonconvertible bonds of
the same  quality  and  maturity,  but they give  holders the option to exchange
their bonds for a specific  number of shares of the company's  common stock at a
predetermined  price.  This  structure  allows the  convertible  bond  holder to
participate in share price movements in the company's  common stock.  The actual
return on a convertible bond may exceed its stated yield if the company's common
stock  appreciates in value,  and the option to convert to common shares becomes
more valuable.

    Convertible  preferred  stocks are nonvoting  equity  securities  that pay a
fixed  dividend.   These  securities  have  a  convertible  feature  similar  to
convertible  bonds;  however,  they do not have a  maturity  date.  Due to their
fixed-income  features,  convertible  issues  typically  are more  sensitive  to
interest  rate  changes  than  the  underlying  common  stock.  In the  event of
liquidation,  bondholders would have claims on company assets senior to those of
stockholders; preferred stockholders would have claims senior to those of common
stockholders.

    Warrants  entitle the holder to buy the issuer's  stock at a specific  price
for a specific  period of time. The price of a warrant tends to be more volatile
than, and does not always track, the price of its underlying stock. Warrants are
issued with expiration  dates.  Once a warrant  expires,  it has no value in the
market.

FOREIGN SECURITIES

    The Fund's investments in securities of foreign issuers may subject the Fund
to additional investment risks.

    Investing in foreign  companies may involve  risks not typically  associated
with investing in U.S. companies. The value of securities denominated in foreign
currencies, and of dividends from such securities, can change significantly when
foreign  currencies  strengthen or weaken relative to the U.S.  dollar.  Foreign
securities  markets  generally  have less trading volume and less liquidity than
U.S. markets, and prices in some foreign markets can be very volatile.

    Many foreign  countries lack uniform  accounting  and  disclosure  standards
comparable to those that apply to U.S.  companies,  and it may be more difficult
to obtain reliable information  regarding a foreign issuer's financial condition
and  operations.  In  addition,  the  costs  of  foreign  investing,   including
withholding  or other taxes,  brokerage  commissions,  and custodial  fees,  are
generally higher than for U.S. investments.

    Foreign  markets may offer less  protection to investors than U.S.  markets.
Foreign  issuers,  brokers,  and  securities  markets  may be  subject  to  less
governmental  supervision.  Foreign security trading practices,  including those
involving  the  release of assets in advance of payment,  may involve  increased
risks in the event of a failed trade or the  insolvency of a  broker-dealer  and
may involve substantial delays. It may also be difficult to enforce legal rights
in foreign countries.

    Investing  abroad  carries  political and economic risks distinct from those
associated  with investing in the U.S.  Foreign  investments  may be affected by
actions  of foreign  governments  adverse to the  interests  of U.S.  investors,
including  the  possibility  of  expropriation  or  nationalization  of  assets,
confiscatory taxation,  restrictions on U.S. investment,  or restrictions on the
ability to repatriate assets or to convert currency into U.S. dollars. There may
be   a   greater    possibility   of   default   by   foreign   governments   or
foreign-government-sponsored  enterprises. Investments in foreign countries also
involve a risk of local political,  economic,  or social  instability,  military
action or unrest, or adverse diplomatic developments.

    To offset the currency  risks  associated  with  investing in  securities of
foreign  issuers,  the Fund may hold foreign  currency  deposits and may convert
dollars  and  foreign  currencies  in the  foreign  exchange  markets.  Currency
conversion involves dealer spreads and


6                                             AMERICAN CENTURY INVESTMENTS


other costs, although commissions usually are not charged.

    Currencies may be exchanged on a spot (i.e.  cash) basis or by entering into
forward  contracts  to purchase or sell  foreign  currencies  at future date and
price. By entering into a forward  contract to buy or sell the amount of foreign
currency involved in a security  transaction for a fixed amount of U.S. dollars,
the Manager can protect the Fund against losses  resulting from adverse  changes
in the relationship  between the U.S. dollar and the foreign currency during the
period  between the date the security is purchased or sold and the date on which
payment is made or  received.  However,  it should be noted  that using  forward
contracts to protect the Fund's foreign  investments from currency  fluctuations
does not  eliminate  fluctuations  in the  prices of the  underlying  securities
themselves.  Forward  contracts  simply establish a rate of exchange that can be
achieved at some future point in time. Additionally,  although forward contracts
tend to  minimize  the risk of loss due to a decline  in the value of the hedged
currency,  they also limit any gain that might  result if the hedged  currency's
value were to increase.

    Foreign  exchange  dealers  do not  charge  fees for  currency  conversions.
Instead,  they realize a profit based on the difference (the spread) between the
prices at which they are buying and  selling  various  currencies.  A dealer may
offer to sell a foreign  currency  at one rate while  simultaneously  offering a
lesser rate of exchange on the purchase of that currency.

DEPOSITARY RECEIPTS

    American  Depositary Receipts and European Depositary Receipts ("ADR"s and "
EDR"s) are receipts  representing  ownership of shares of a foreign-based issuer
held in trust by a bank or similar financial institution. These are designed for
U.S. and European  securities  markets as alternatives to purchasing  underlying
securities in their corresponding national markets and currencies. ADRs and EDRs
can be sponsored or unsponsored.

    Sponsored  ADRs  and  EDRs are  certificates  in  which a bank or  financial
institution participates with a custodian.  Issuers of unsponsored ADRs and EDRs
are not contractually  obligated to disclose material  information in the United
States.  Therefore,  there may not be a correlation between such information and
the market value of the unsponsored ADR or EDR.

RESTRICTED SECURITIES

    Restricted  securities  held by the Fund  generally can be sold in privately
negotiated  transactions,  pursuant to an exemption from registration  under the
Securities Act of 1933, or in a registered public offering.  Where  registration
is required,  the Fund may be required to pay all or a part of the  registration
expense,  and a  considerable  period may elapse  between the time it decides to
seek  registration  of the  securities and the time it is permitted to sell them
under an effective  registration  statement.  If,  during this  period,  adverse
market conditions were to develop,  the Fund might obtain a less favorable price
than prevailed when it decided to try to register the securities initially.

SECURITIES LENDING

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

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

    If a borrower fails  financially,  there may be delays in recovering  loaned
securities  and a loss in the value of collateral.  However,  loans will only be
made to parties that meet the guidelines prescribed by the Board of Trustees.

FOREIGN CURRENCY EXCHANGE TRANSACTIONS

    The Manager may engage in foreign currency  exchange  transactions on behalf
of the Fund to manage  currency  risk.  Foreign  currencies may be purchased and
sold regularly, either in the spot (i.e., cash)


STATEMENT OF ADDITIONAL INFORMATION                                      7


market or in the forward  market  (through  forward  foreign  currency  exchange
contracts, or "forward contracts").  Foreign exchange dealers do not charge fees
for currency conversions. Instead, they realize a profit based on the difference
(the  spread)  between the prices at which they are buying and  selling  various
currencies.  A dealer  may offer to sell a foreign  currency  at one rate  while
simultaneously  offering  a lesser  rate of  exchange  on the  purchase  of that
currency.

    When the Fund  agrees  to buy or sell a  security  denominated  in a foreign
currency,  it may enter  into a forward  contract  to "lock in" the U.S.  dollar
price of the security.  By entering  into a forward  contract to buy or sell the
amount of foreign currency involved in the underlying securities transaction for
a fixed  amount of U.S.  dollars,  the Manager  can  protect the Fund  against a
possible loss resulting from an adverse change in the  relationship  between the
U.S.  dollar and the foreign  currency  between the security's  purchase or sale
date and its payment date. This type of transaction is sometimes  referred to as
a "position hedge."

    In addition to position  hedges,  the Manager may engage in  "cross-hedging"
transactions  on behalf of the Fund.  Cross  hedging  involves  entering  into a
forward contract to sell one foreign  currency and buy another.  The Manager may
employ a  cross-hedging  strategy on behalf of the Fund if it believes  that one
foreign currency (in which a portion of the Fund's foreign currency holdings are
denominated)  will change in value relative to the U.S. dollar  differently than
another foreign currency.

    Successful  use of  forward  contracts  depends  on the  Manager's  skill in
analyzing and predicting  currency  values.  Forward  contracts  could result in
losses to the Fund if currencies do not perform as anticipated. The advisor uses
forward  contracts for currency  hedging purposes only. The adviser does not use
forward  contracts for speculative  purposes.  The Fund is not required to enter
into forward  contracts  with regard to its foreign  holdings and will not do so
unless it is deemed appropriate by the advisor.

    The  Fund's  assets  are  valued  daily in U.S.  dollars,  although  foreign
currency  holdings are not  physically  converted  into U.S.  dollars on a daily
basis.

    The currency  management  techniques  discussed above are limited by various
constraints,  including the intention to protect the U.S. tax status of the Fund
as a regulated investment company.

SHORT SALES AND PUT OPTIONS ON INDIVIDUAL SECURITIES

    The Fund may buy puts and enter  into  short  sales  with  respect to stocks
underlying  its  convertible  security  holdings.  For  example,  if the Manager
anticipates  a  decline  in the  price of the  stock  underlying  a  convertible
security  the Fund holds,  it may purchase a put option on the stock or sell the
stock short. If the stock price subsequently declines, the proceeds of the short
sale or an increase  in the value of the put option  could be expected to offset
all or a  portion  of the  effect  of the  stock's  decline  on the value of the
convertible security.

    When a Fund enters into a short sale,  it will be required to set aside cash
or  appropriate  liquid  assets  in kind and  amount  to those  sold  short  (or
securities  convertible  or  exchangeable  into  such  securities)  and  will be
required to continue to hold them while the short sale is outstanding.  The Fund
will incur transaction costs,  including  interest expenses,  in connection with
opening, maintaining, and closing short sales.

FUTURES AND OPTIONS TRANSACTIONS

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

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

    To initiate and maintain open  positions in futures  contracts,  the Fund is
required to make a good faith margin  deposit in cash or  government  securities
with a broker or custodian. A margin deposit is intended to assure completion of
the contract (delivery or acceptance of the underlying security) if it is not


8                                             AMERICAN CENTURY INVESTMENTS


terminated  prior  to  the  specified  delivery  date.  Minimum  initial  margin
requirements  are  established by the futures  exchanges and may be revised.  In
addition,  brokers may establish  deposit  requirements that are higher than the
exchange minimums.

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

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

    Although  techniques  other than trading  futures  contracts  can be used to
control the Fund's exposure to market fluctuations, the use of futures contracts
may be a more  effective  means of hedging  this  exposure.  While the Fund pays
brokerage  commissions  in  connection  with  opening  and  closing  out futures
positions,  these  costs are lower than the  transaction  costs  incurred in the
purchase and sale of the underlying securities.

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

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

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

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

    If security  prices were to rise,  a put writer  would  generally  expect to
profit,  although  the gain  would  be  limited  to the  amount  of the  premium
received. If security prices were to remain the same over time, the writer would
likely also profit by being able to


STATEMENT OF ADDITIONAL INFORMATION                                    9


close out the option at a lower price.  If security prices were to fall, the put
writer  would  expect to suffer a loss.  This loss  should be less than the loss
from purchasing the underlying instrument directly, however, because the premium
received for writing the option should mitigate the effects of the decline.

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

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

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

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

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

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


10                                             AMERICAN CENTURY INVESTMENTS


options or futures positions are poorly  correlated with its other  investments,
the positions may fail to produce anticipated gains or result in losses that are
not offset by gains in other investments.

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

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

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

    LIQUIDITY OF FUTURES  CONTRACTS AND OPTIONS.  There is no assurance a liquid
secondary market will exist for any particular futures contract or option at any
particular time. Options may have relatively low trading volume and liquidity if
their strike prices are not close to the underlying  instrument's current price.
In addition,  exchanges may establish daily price fluctuation limits for futures
contracts and options and may halt trading if a contract's price moves upward or
downward  more than the limit on a given day. On volatile  trading days when the
price  fluctuation  limit is reached  or a trading  halt is  imposed,  it may be
impossible  for the  Fund to enter  into new  positions  or close  out  existing
positions.  If the secondary  market for a contract were not liquid,  because of
price  fluctuation  limits  or  otherwise,  prompt  liquidation  of  unfavorable
positions  could be difficult or  impossible,  and the Fund could be required to
continue  holding a position until delivery or expiration  regardless of changes
in its value.  Under these  circumstances,  the Fund's  access to assets held to
cover its future positions could also be impaired.

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

RESTRICTIONS ON THE USE OF FUTURES CONTRACTS AND OPTIONS

    The Fund has filed a notice of  eligibility  for  exclusion  as a "commodity
pool  operator"  with the  CFTC  and the  National  Futures  Association,  which
regulates  trading in the  futures  markets.  The Fund  intends  to comply  with
Section 4.5 of the  regulations  under the Commodity  Exchange Act, which limits
the extent to which the Fund can commit  assets to initial  margin  deposits and
options premiums.

    The Fund may enter into futures transactions (including related options) for
hedging purposes without regard to the percentage of assets committed to initial
margin and for other than hedging  purposes  provided  that assets  committed to
initial margin deposits on such instruments, plus premiums paid for open futures
options  positions,   less  the  amount  by  which  any  such  positions  are  "
in-the-money,"  do not  exceed 5% of the  Fund's  total  assets.  To the  extent
required by law, the Fund will set aside cash or appropriate  liquid assets in a
segregated  account to cover its  obligations  related to futures  contracts and
options.  Financial  futures  or options  purchased  or sold by the Fund will be
standardized  and traded through the facilities of a U.S. or foreign  securities
association or listed on a U.S. or foreign  securities or commodities  exchange,
board of trade, or similar entity,  or quoted on an automatic  quotation system,
except that the Fund may effect  transactions in  over-the-counter  options with
primary U.S.  government  securities  dealers  recognized by the Federal Reserve
Bank of New  York.  In  addition,  the Fund has  undertaken  to limit  aggregate
premiums  paid on all options  purchased  by the Fund to no more than 20% of the
Fund's total net asset value.


STATEMENT OF ADDITIONAL INFORMATION                                       11


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

INVESTMENT RESTRICTIONS

    The Fund's  investment  restrictions set forth below are fundamental and may
not  be  changed  without  approval  of a  majority  of the  outstanding  voting
securities of the Fund, as defined in the Investment Company Act of 1940.

    THE FUND MAY NOT:

  (1)    Purchase the securities of any issuer (other than securities  issued or
         guaranteed by the U.S. government,  its agencies or  instrumentalities)
         if, as a result,  at the time of such  investment,  (a) more than 5% of
         its total assets would be invested in the securities of that issuer, or
         (b) the  Fund  would  hold  more  than  10% of the  outstanding  voting
         securities of that issuer.

  (2)    Borrow  money  except  from a bank as a  temporary  measure  to satisfy
         redemption requests or for extraordinary or emergency purposes provided
         that the Fund  maintains  asset  coverage of at least 300% for all such
         borrowings.  The Fund will not purchase any security  while  borrowings
         representing more than 5% of its total assets are outstanding. The Fund
         may borrow money for  temporary or emergency  purposes from other funds
         or portfolios for which the Manager is the investment  advisor, or from
         a joint  account of such funds or  portfolios,  as permitted by federal
         regulatory  agencies,  and  provided  it  has  received  any  necessary
         exemptive order from the Securities and Exchange Commission.

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

  (4)    Purchase  or sell real  estate  or real  estate  limited  partnerships,
         unless  acquired  as a  result  of  ownership  of  securities  or other
         instruments  (but this shall not  prevent  the Fund from  investing  in
         securities  or other  instruments  backed  by real  estate  or  readily
         marketable  securities of issuers engaged in the real estate business);
         physical commodities;  contracts relating to physical  commodities;  or
         interests in oil, gas and/or mineral exploration  development  programs
         or leases.  This  restriction  shall not be deemed to prohibit the Fund
         from purchasing or selling currencies;  entering into futures contracts
         on  securities,  currencies,  or  on  indexes  of  such  securities  or
         currencies,  or any other  financial  instruments;  and  purchasing and
         selling options on such futures contracts.

  (5)    Make loans to others,  except for the lending of  portfolio  securities
         pursuant to guidelines  established by the Board of Trustees and except
         as otherwise in  accordance  with the Fund's  investment  objective and
         policies.

  (6)    Issue  senior  securities,  except as  permitted  under the  Investment
         Company Act of 1940.

  (7)    Purchase any security if, as a result,  25% or more of the Fund's total
         assets  would be invested in the  securities  of issuers  having  their
         principal  business  activities  in the same  industry.  However,  this
         limitation  does not apply to  securities  issued or  guaranteed by the
         U.S. government or any of its agencies or instrumentalities.

    The  Fund  is  also  subject  to the  following  restrictions  that  are not
fundamental  and may,  therefore,  be changed by the Board of  Trustees  without
shareholder approval.

    THE FUND MAY NOT:

  (a)    Sell  securities  short,  unless  it owns or has the  right  to  obtain
         securities  equivalent in kind and amount to the securities sold short,
         and provided that transactions in options and futures contracts are not
         deemed to constitute short sales of securities.

  (b)    Purchase warrants,  valued at the lower of cost or market, in excess of
         10% of the Fund's net assets.  Included within that amount,  but not to
         exceed 2% of the Fund's  net  assets,  are  warrants  whose  underlying
         securities are not traded on principal  domestic or foreign  exchanges.
         Warrants  acquired by the Fund in units or attached to  securities  are
         not subject to these restrictions.


12                                             AMERICAN CENTURY INVESTMENTS


  (c)    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 the purchase of
         securities on margin.

  (d)    Invest  in  securities  that are not  readily  marketable,  or that are
         illiquid because they are subject to legal or contractual  restrictions
         on resale (collectively,  "illiquid  securities") if, as a result, more
         than 15% of the  Fund's  net  assets  would  be  invested  in  illiquid
         securities.

  (e)    Acquire or retain the securities of any other investment company if, as
         a result, more than 3% of such investment company's  outstanding shares
         would be held by the  Fund,  more  than 5% of the  value of the  Fund's
         assets would be invested in shares of such investment  company, or more
         than 10% of the value of the Fund's  assets would be invested in shares
         of investment  companies in the aggregate,  except in connection with a
         merger,  consolidation,  acquisition, or reorganization or as otherwise
         permitted by applicable law.

  (f)    Invest in securities of an issuer that,  together with any  predecessor
         or unconditional  guarantor,  has been in operation for less than three
         years  if, as a  result,  more than 5% of the total  assets of the Fund
         would then be invested in such securities, except obligations issued or
         guaranteed by the U.S. government or its agencies.

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

    For purposes of the Fund's investment restrictions,  the party identified as
the "issuer" of a municipal  security  depends on the form and conditions of the
security.  When the assets and revenues of a political  subdivision are separate
from those of the government  that created the  subdivision  and the security is
backed only by the assets and revenues of the  subdivision,  the  subdivision is
deemed the sole issuer. Similarly, in the case of an Industrial Development Bond
("IDB"),  if  the  bond  were  backed  only  by the  assets  and  revenues  of a
non-governmental  user,  the  non-governmental  user  would be  deemed  the sole
issuer. If, in either case, the creating government or some other entity were to
guarantee the security,  the guarantee  would be considered a separate  security
and treated as an issue of the guaranteeing entity.

PORTFOLIO TRANSACTIONS

    The Fund's  assets are invested by the Manager in a manner  consistent  with
the Fund's  investment  objectives,  policies,  and  restrictions,  and with any
instructions  the Board of  Trustees  may issue from time to time.  Within  this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement securities transactions on behalf of the Fund.

    In placing  orders for the purchase and sale of  portfolio  securities,  the
Manager  will  use its best  efforts  to  obtain  the best  possible  price  and
execution and will otherwise place orders with broker-dealers  subject to and in
accordance  with any  instructions  the Board of Trustees may issue from time to
time. The Manager will select  broker-dealers to execute portfolio  transactions
on behalf of the Fund solely on the basis of best price and execution.

    The Fund's annual portfolio  turnover rate for the  fixed-income  portion of
its  portfolio  is not  expected  to exceed  250%;  the  equity  portion  of its
portfolio  is not expected to exceed 150%.  These  turnover  rates may vary from
year to year. Because a higher turnover rate increases transaction costs and may
increase taxable gains, the advisor  carefully weighs the potential  benefits of
short-term investing against these considerations.

VALUATION OF PORTFOLIO SECURITIES

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


STATEMENT OF ADDITIONAL INFORMATION                                    13


    Although the Fund  expects the same  holiday  schedule to be observed in the
future, the Exchange may modify its holiday schedule at any time.

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

    If no sale is reported,  the mean between the latest bid and asked prices is
used. Securities traded  over-the-counter will be valued at the mean between the
latest bid and asked prices.

PERFORMANCE

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

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


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

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

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

    The Fund's  average  annual total returns for the one-year and  life-of-fund
periods ended November 30, 1996, are indicated in the following table.

                  Average Annual Total Return
- ---------------------------------------------------
One Year                    15.58%

Life-of-Fund*               17.65%
- ---------------------------------------------------
* Since Fund inception on December 1, 1994.


    In addition to average annual total returns,  the Fund may quote  unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment over a stated period. Average annual and cumulative total returns may
be quoted as a  percentage  or as a dollar  amount and may be  calculated  for a
single investment, a series of investments,  or a series of redemptions over any
time period.  Total  returns may be broken down into their  components of income
and capital  (including  capital gains and changes in share price) to illustrate
the relationship of these factors and their contributions to total return.

    The Fund's performance may be compared with the performance of other mutual
funds tracked by


14                                             AMERICAN CENTURY INVESTMENTS


mutual fund rating  services or with other indexes of market  performance.  This
may include comparisons with funds that, unlike American Century funds, are sold
with a sales charge or deferred sales charge.  Sources of economic data that may
be used for such comparisons may include,  but are not limited to, U.S. Treasury
bill, note, and bond yields,  money market fund yields, U.S. government debt and
percentage  held by foreigners,  the U.S. money supply,  net free reserves,  and
yields on  current-coupon  GNMAs  (source:  Board of  Governors  of the  Federal
Reserve System);  the federal funds and discount rates (source:  Federal Reserve
Bank of New York);  yield curves for U.S.  Treasury  securities and AA/AAA-rated
corporate  securities (source:  Bloomberg  Financial Markets);  yield curves for
AAA-rated tax-free municipal  securities  (source:  Telerate);  yield curves for
foreign government  securities  (sources:  Bloomberg  Financial Markets and Data
Resources, Inc.); total returns on foreign bonds (source: J.P. Morgan Securities
Inc.);  various  U.S.  and  foreign  government  reports;  the junk bond  market
(source: Data Resources,  Inc.); the CRB Futures Index (source:  Commodity Index
Report); the price of gold (sources:  London a.m./p.m. fixing and New York Comex
Spot  Price);  rankings of any mutual fund or mutual  fund  category  tracked by
Lipper  Analytical  Services,  Inc. or Morningstar,  Inc.;  mutual fund rankings
published in major  nationally  distributed  periodicals;  data  provided by the
Investment Company Institute;  Ibbotson  Associates,  Stocks,  Bonds, Bills, and
Inflation; major indexes of stock market performance; and indexes and historical
data supplied by major  securities  brokerage or investment  advisory firms. The
Fund may also utilize reprints from newspapers and magazines  furnished by third
parties to illustrate historical performance.

    Indexes may assume reinvestment of dividends,  but,  generally,  they do not
reflect  administrative  and management costs such as those incurred by a mutual
fund.

    Occasionally  statistics may be used to illustrate  Fund volatility or risk.
Measures  of  volatility  or risk  generally  are used to compare the Fund's net
asset value or  performance  to a market  index.  One measure of volatility is "
beta."  Beta  expresses  Fund  volatility   relative  to  the  total  market  as
represented  by the S&P  500.  A beta of more  than  1.00  indicates  volatility
greater  than  that  of the  market,  and a beta  of less  than  1.00  indicates
volatility  less than that of the market.  Another measure of volatility or risk
is "standard  deviation."  Standard deviation is used to measure  variability of
net asset value or total return  relative to an average over a specified  period
of time. The premise is that greater volatility connotes greater risk undertaken
to achieve desired performance.

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

TAXES

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

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

    The Fund's  transactions in foreign currencies,  forward contracts,  options
and  futures  contracts  (including  options and  futures  contracts  on foreign
currencies) will be subject to special  provisions of the Code that, among other
things, may affect the character of gains and losses realized by the Fund (i.e.,
may  affect  whether  gains or  losses  are  ordinary  or  capital),  accelerate
recognition  of  income  to  the  Fund,  defer  Fund  losses,   and  affect  the
determination of whether capital gains and losses are characterized as long-term
or short-term capital gains or losses. These rules


STATEMENT OF ADDITIONAL INFORMATION                                      15


could  therefore  affect the character,  amount and timing of  distributions  to
shareholders.  These  provisions also may require a Fund to market certain types
of the positions in its portfolio (i.e., treat them as if they were closed out),
which may cause the Fund to recognize  income without  receiving cash with which
to  make  distributions  in  amounts  necessary  to  satisfy  the  90%  and  98%
distribution requirements for relief from income and excise taxes. The Fund will
monitor its  transactions  and may make such tax  elections  as Fund  management
deems appropriate with respect to foreign currency,  options, futures contracts,
forward  contracts,  or hedged  investments.  The Fund's  status as a  regulated
investment  company  may  limit its  transactions  involving  foreign  currency,
futures, options, and forward contracts.

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

    The Fund may invest in shares of foreign corporations that may be classified
under the Code as passive foreign investment companies ("PFIC"s).  In general, a
foreign  corporation  is classified as a PFIC is at least one-half of its assets
constitute passive  investment-type assets or 75% or more of its gross income is
passive investment-type income. Certain distributions from a PFIC and gains from
the sale of PFIC  shares  are  treated  as excess  distributions.  These  excess
distributions  and gains may subject the Fund to  non-deductible  federal income
tax.

    The Fund will monitor its  transactions  and may make such tax  elections as
Fund management  deems  appropriate  with respect to its holdings in PFICs.  The
Fund's intention to qualify annually as a regulated investment company may limit
its elections with respect to PFIC shares.

    Because the  application  of the PFIC rules may affect,  among other things,
the  character  of  gains,  the  amount of gain or loss,  and the  timing of the
recognition  of income with respect to PFIC shares,  as well as subject the Fund
itself to tax on excess  distributions from PFIC shares, the amount that must be
distributed to  shareholders,  which will be taxed to  shareholders  as ordinary
income or long-term  capital gain,  may be increased or decreased  substantially
compared to a fund that did not invest in PFIC shares.

    Earnings  derived by the Fund from sources  outside the United States may be
subject to non-U.S.  withholding  and possibly  other  taxes.  Such taxes may be
reduced or eliminated under the terms of a U.S. income tax treaty,  and the Fund
generally  intends to  undertake  any  procedural  steps  required  to claim the
benefits of such a treaty.  Generally,  such taxes will reduce the Fund's income
distributable  to  shareholders.  This Fund will not qualify to pass through any
such foreign taxes to the Fund's shareholders.

    Some of the debt  securities that may be acquired by the Fund may be treated
as debt  securities  that are originally  issued at a discount.  Generally,  the
amount of the original issue discount  ("OID") is treated as interest income and
is included in income over the term of the debt security, even though payment of
that amount is not received  until a later time,  usually when the debt security
matures. Therefore,  distribution of this income may be required even though the
Fund would not have received the cash with which to make the distribution.

    Some of the debt securities may be purchased in the secondary  market by the
Fund at a  discount  that  exceeds  the  original  issue  discount  on such debt
securities,  if any. This  additional  discount  represents  market discount for
federal income tax purposes. The gain realized on the disposition of any taxable
debt security  having market  discount will be treated as ordinary income to the
extent it does not exceed the  accrued  market  discount  on such debt  security
previously  included in the Fund's  investment  company taxable  income.  At the
election of the Fund,  market discount accrues for tax purposes on a daily basis
for each day


16                                             AMERICAN CENTURY INVESTMENTS


the debt security is held by the Fund at a constant rate over the time remaining
to the debt  security's  maturity or, at the election of the Fund, at a constant
yield to  maturity  that  takes  into  account  the  semiannual  compounding  of
interest.

    Generally, the Fund will be required to distribute to shareholders dividends
representing  the accretion of discounts on debt  securities  that are currently
includable  in  income,  even if cash  representing  such  income  has not  been
received by the Fund.  Cash to pay such  dividends may be obtained from proceeds
of sales of securities held by the Fund.

    Exchange control  regulations  that may restrict  repatriation of investment
income,  capital,  or the proceeds of securities sales by foreign  investors may
limit the Fund's  ability to make  sufficient  distributions  to satisfy the 90%
income tax and 98% excise tax distribution requirements.

    Ordinarily, the Fund will declare and pay dividends of net investment income
quarterly and make distributions of net realized capital gains, if any, at least
annually.

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

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

    The  information  above is only a summary of some of the tax  considerations
generally  affecting the Fund and its shareholders.  No attempt has been made to
discuss  individual  tax  consequences.  The  Fund's  distributions  may also be
subject to state,  local, or foreign taxes. U.S. tax rules applicable to foreign
investors  may differ  significantly  from those  outlined  above.  To determine
whether  the Fund is a  suitable  investment  based on his or her tax  situation
prospective investor may wish to consult a tax advisor.

ABOUT AMERICAN CENTURY MANAGER FUNDS

    American  Century  Manager  Funds (the  "Trust")  is a  registered  open-end
management  investment  company that was organized as a  Massachusetts  business
trust on July 12, 1994. The Trust was formerly known as "Benham  Manager Funds."
American Century Capital Manager Fund (formerly known as "Benham Capital Manager
Fund" until January  1997) is currently the sole series of the Trust.  The Board
of Trustees may create additional series from time to time.

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

    If  additional  series were  created by the Board of  Trustees,  each series
would vote  separately  on matters  affecting  that series  exclusively.  Voting
rights are not cumulative so that investors holding more than 50% of the Trust's
outstanding  shares  may  elect  a  Board  of  Trustees.  The  Trust  instituted
dollar-based  voting,  meaning  that the number of votes you are  entitled to is
based upon the dollar  amount of your  investment.  The  election of Trustees is
determined by the votes received from all Trust  shareholders  without regard to
whether a majority  of shares of any one series  voted in favor of a  particular
nominee or all nominees as a group.  Shareholders have equal rights to dividends
and  distributions  declared  by the Fund and to the net assets of the Fund upon
its  liquidation  or  dissolution  proportionate  to his or her share  ownership
interest in the Fund.

    Shareholders  of  a  Massachusetts   business  trust  could,  under  certain
circumstances,  be held  personally  liable for its  obligations.  However,  the
Declaration of Trust contains an express disclaimer of shareholder


STATEMENT OF ADDITIONAL INFORMATION                                     17


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

investment  policies or in determining which securities are sold or purchased by

advised by the Manager.

MANAGEMENT

    The  Fund  has an  investment  advisory  agreement  with  Benham  Management
Corporation,  dated June 1, 1995,  that was approved by  shareholders on May 31,
1995.

    The Manager is a California corporation and became a wholly owned subsidiary
of ACC on June 1, 1995. The Manager has served as investment advisor to the Fund
since the Fund's inception.  ACC is a holding company that owns all of the stock
of the operating  companies  that provide the  investment  management,  transfer
agency,  shareholder service, and other services for the American Century funds.
James E. Stowers,  Jr., controls ACC by virtue of his ownership of a majority of
its common  stock.  The Manager has been a registered  investment  advisor since
1971.

    The Fund's agreement with the Manager continues for an initial period of two
years and thereafter from year to year provided that, after the initial two year
period,  it is  approved  at least  annually by vote of either a majority of the
Fund's  outstanding  voting  securities  or by vote of a majority  of the Fund's
Trustees,  including a majority of those Trustees who are neither parties to the
agreement nor interested  persons of any such party, cast in person at a meeting
called for the purpose of voting on such approval.

    The investment  advisory agreement is terminable on 60 days' written notice,
either  by the  Fund or by the  Manager,  to the  other  party,  and  terminates
automatically in the event of its assignment.

    Pursuant to the investment advisory agreement, the Manager provides the fund
with investment advice and portfolio  management services in accordance with the
Fund's investment objective,  policies, and restrictions. The Manager determines
what  securities  will be purchased and sold by the Fund and assists the Trust's
officers in carrying out decisions made by the Board of Trustees.

    For these services, the Fund pays the Manager a monthly investment advisory
fee based on its pro rata


STATEMENT OF ADDITIONAL INFORMATION                                    19


share of the dollar amount  derived from applying the Trust's  average daily net
assets to the following investment advisory fee rate schedule:


          0.65% of the first $100 million; 
          0.60% of the next $100 million; 
          0.55% of the next $100 million; 
          0.50% of the next $100 million; 
          0.45% of the next $100 million;

          0.31% of the next $1 billion; 
          0.30% of the next $1 billion; 
          0.29% of the next $1 billion; 
          0.28% of the next $1 billion; and
          0.27% of the average daily net assets over $6.5 billion


    Investment advisory fee paid by the Fund for the fiscal years ended November
30, 1995 and 1996, are $22,524 and $332,953,  respectively.  Fee amounts are net
of reimbursements.

TRANSFER AND ADMINISTRATIVE SERVICES

    American  Century  Services  Corporation,  4500 Main  Street,  Kansas  City,
Missouri,  64111, (ACS) acts as transfer,  administrative  services and dividend
paying agent for the Fund. ACS provides  facilities,  equipment and personnel to
the Fund and is paid for such services by the Fund. For administrative services,
the Fund pays ACS a monthly fee equal to its pro rata share of the dollar amount
derived from  applying the average  daily net assets of all of the funds advised
by the Manager to the following administrative fee rate schedule:


Group Assets                       Administrative Fee Rate
- -------------------------------------------------------------------------
up to $4.5 billion                            .11%

over $9 billion                               .08
- -------------------------------------------------------------------------


    For transfer agent services,  the Fund pays ACS a monthly fee of $1.1875 for
each shareholder  account maintained and $1.35 for each shareholder  transaction
executed during that month.

    The Fund paid $29,031 and $78,439 in administrative service fees and $59,873
and $87,034 in transfer  agent fees net of  reimbursements  for the fiscal years
ended November 30, 1995 and 1996, respectively.

SPECIAL MEETING OF SHAREHOLDERS

At a Special Meeting of Shareholders held on July 30, 1997,  shareholders of the
Funds approved, among other things, a new Management Agreement between the Funds
with American Century Investment Management,  Inc. This new Management Agreement
will  become  effective  on August 1, 1997,  and  replaces  the  Funds'  current
investment advisory agreement with Benham Management  Corporation,  an affiliate
of American Century Investment Management, Inc.

At the meeting, shareholders of the Funds also ratified the selection of Coopers
& Lybrand LLP as the  independent  auditors for each Fund's  current fiscal year
and approved the adoption of standardized  investment limitations by amending or
eliminating  certain  of the  Funds'  fundamental  investment  limitations.  The
changes resulting from the Special Meeting of Shareholders are reflected in this
Prospectus Supplement and in the revised Statement of Additional  Information of
the Funds.

FUTURES CONTRACTS AND OPTIONS

On page 9, the heading  "Interest Rate Futures Contracts and Options Thereon" is
deleted and  replaced  with  "Futures  Contracts  and  Options."  The first full
paragraph  appearing  under the current heading is deleted and replaced with the
following:

     The  Funds  may  buy or  sell  futures  contracts  relating  to  groups  of

futures contracts.

INVESTMENT MANAGEMENT

On page 20, the first two paragraphs in the subsection  "Investment  Management"
are deleted and replaced with the following:

     The Funds are series of the American Century Quantitative Equity Funds (the
"Company"). Under the laws of the State of California, the Board of Directors is
responsible  for  managing  the  business  and  affairs of the  Company.  Acting
pursuant to an  investment  management  agreement  entered  into with the Funds,
American Century Investment Management, Inc. serves as the investment manager of
the Funds. Its principal place of business is American Century Tower,  4500 Main
Street,  Kansas City, Missouri 64111. The Manager has been providing  investment
advisory services to investment companies and institutional clients since it was
founded in 1958.

On page 21, the four full  paragraphs  before the  subsection  heading  "Code of
Ethics" are deleted and replaced with the following:

     The  members  of  the  American  Century   quantitative   equity  portfolio
management  team  responsible  for  management  of  Income  &  Growth  are  John
Schniedwind and Kurt Borgwardt. The members of the American Century quantitative
equity portfolio management team responsible for management of Equity Growth are
Jeff Tyler and William Martin.

     JOHN  SCHNIEDWIND,  Senior Vice  President  and Group  Leader--Quantitative
Equity,  has been a member of the team that  manages  Income & Growth  since its
inception  and has  supervised  the teams that manage  Equity  Growth  since its
inception.  Mr.  Schniedwind joined American Century in 1982 and also supervises
the portfolio  management  teams which manage American Century Global Gold Fund,
American Century Global Natural  Resources Fund and American  Century  Utilities
Fund.

     JEFF TYLER,  Senior Vice President and Portfolio  Manager,  joined the team
managing Equity Growth in May 1997. Mr. Tyler joined  American  Century in 1988.
Mr.  Tyler is also  responsible  for the  supervision  of the  American  Century
Strategic  Asset  Allocation  Funds and the  American  Century--Benham  European
Government  Bond Fund.  Prior to May 1997,  Mr. Tyler  supervised  the portfolio
management teams for American Century's government bond and money market funds.

     WILLIAM  MARTIN,  Senior Vice President and Portfolio  Manager,  joined the
team  managing  Equity  Growth in May 1997.  Mr.  Martin  also has served on the
management  team for American  Century  Global Gold and American  Century Global
Natural Resources Funds since their respective inception dates.

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

     For the services  provided to the Funds, the Manager receives a monthly fee
based on a percentage of the average net assets of the Fund.  The annual rate at
which this fee is assessed is determined monthly in a two-step process: First, a
fee rate  schedule  is  applied  to the  assets  of all of the funds in a Fund's
investment  category which are managed by the Manager (the "Investment  Category
Fee"). There are three investment categories: Money Market Funds, Bond Funds and
Equity Funds.  Second,  a separate fee rate schedule is applied to the assets of
all of the  mutual  funds  managed  by the  Manager  (the  "Complex  Fee").  The
Investment  Category  Fee and the  Complex Fee are then added to  determine  the
unified  management  fee  payable  by the Fund to the  Manager.  Currently,  the
Investment  Category Fee for each of the Funds is an annual rate of 0.40% of the
average net assets of the Fund.  The Complex Fee is  currently an annual rate of
0.30% of the  average  net  assets  of a Fund.  Further  information  about  the
calculation  of the annual  management  fee is  contained  in the  Statement  of
Additional Information.

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

TRANSFER AND ADMINISTRATIVE SERVICES

On page 27, the first paragraph under the heading  "Transfer and  Administrative
Services" is deleted and replaced with the following:

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

EXPENSES

On page 28, the subsection called "Expenses" is deleted.

INVESTMENT POLICIES AND TECHNIQUES

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

U.S. GOVERNMENT SECURITIES

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

REPURCHASE AGREEMENTS

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

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

     The  Funds  have  received  permission  from the  Securities  and  Exchange
Commission (SEC) to participate in joint repurchase agreements collateralized by
U.S. government securities with other mutual funds advised by the Manager. Joint
repos  are  expected  to  increase  the  income  the  Funds  can earn  from repo
transactions without increasing the risks associated with these transactions.

WHEN-ISSUED AND FORWARD
COMMITMENT AGREEMENTS

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

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

     In purchasing  securities on a when-issued or forward  commitment  basis, a
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash or appropriate  liquid assets including equity securities and
debt securities of any grade in an amount sufficient to meet the purchase price.
When the time comes to pay for the when-issued securities,  a Fund will meet its
obligations with available cash, through the sale of securities, or, although it
would not  normally  expect  to do so, by  selling  the  when-issued  securities
themselves


2                                                American Century Investments


(which  may  have a  market  value  greater  or less  than  the  Fund's  payment
obligation).  Selling  securities  to meet  when-issued  or  forward  commitment
obligations may generate taxable capital gains or losses.

CONVERTIBLE SECURITIES

     Each Fund may buy securities that are convertible into common stock. Listed
below is a brief description of the various types of convertible  securities the
Funds may buy.

     CONVERTIBLE BONDS are issued with lower coupons than  nonconvertible  bonds
of the same quality and  maturity,  but they give holders the option to exchange
their bonds for a specific  number of shares of the company's  common stock at a
predetermined  price.  This  structure  allows the  convertible  bond  holder to
participate in share price movements in the company's  common stock.  The actual
return on a convertible bond may exceed its stated yield if the company's common
stock  appreciates  in value and the option to convert to common shares  becomes
more valuable.

     CONVERTIBLE  PREFERRED  STOCKS are nonvoting  equity  securities that pay a
fixed  dividend.   These  securities  have  a  convertible  feature  similar  to
convertible  bonds;  however,  they do not have a  maturity  date.  Due to their
fixed-income  features,  convertible  issues  typically  are more  sensitive  to
interest  rate  changes  than  the  underlying  common  stock.  In the  event of
liquidation,  bondholders would have claims on company assets senior to those of
stockholders; preferred stockholders would have claims senior to those of common
stockholders.

     WARRANTS  entitle the holder to buy the issuer's  stock at a specific price
for a specific  period of time. The price of a warrant tends to be more volatile
than, and does not always track,  the price of its under-lying  stock.  Warrants
are issued with expiration dates. Once a warrant expires, it has no value in the
market.

FOREIGN SECURITIES

     Although  the  Funds may buy  securities  of  foreign  issuers  in  foreign
markets,  most of their foreign  securities  investments  are made by purchasing
American  Depositary  Receipts (ADRs),  "ordinary shares," or "New York Shares."
The Funds may invest in  foreign-currency-denominated  securities  that trade in
foreign  markets  if  the  Manager   believes  that  such  investments  will  be
advantageous to the Funds.

     ADRs  are   dollar-denominated   receipts  representing  interests  in  the
securities  of a foreign  issuer.  They are  issued by U.S.  banks and traded on
exchanges or over the counter in the United States.  Ordinary  shares are shares
of foreign  issuers  that are traded  abroad  and on a U.S.  exchange.  New York
shares are shares that a foreign  issuer has allocated for trading in the United
States. ADRs, ordinary shares, and New York shares all may be purchased with and
sold for U.S. dollars, which protects the Fund from the foreign settlement risks
described below.

     Investing in foreign  companies may involve risks not typically  associated
with investing in U.S. companies. The value of securities denominated in foreign
currencies and of dividends from such securities can change  significantly  when
foreign  currencies  strengthen or weaken relative to the U.S.  dollar.  Foreign
securities  markets  generally  have less trading volume and less liquidity than
U.S. markets, and prices in some foreign markets can be very volatile.

     Many foreign  countries lack uniform  accounting  and disclosure  standards
comparable to those that apply to U.S.  companies,  and it may be more difficult
to obtain reliable information  regarding a foreign issuer's financial condition
and  operations.  In  addition,  the  costs  of  foreign  investing,   including
withholding  taxes,  brokerage  commissions,  and custodial  fees, are generally
higher than for U.S. investments.

     Foreign markets may offer less  protection to investors than U.S.  markets.
Foreign  issuers,  brokers,  and  securities  markets  may be  subject  to  less
governmental  supervision.  Foreign security trading practices,  including those
involving  the  release of assets in advance of payment,  may involve  increased
risks in the event of a failed trade or the  insolvency of a  broker-dealer  and
may involve substantial delays. It may also be difficult to enforce legal rights
in foreign countries.

     Investing  abroad carries  political and economic risks distinct from those
associated  with investing in the United  States.  Foreign  invest-ments  may be
affected  by actions of foreign  governments  adverse to the  interests  of U.S.
investors,  including the possibility of  expro-priation or  nationalization  of
assets, confiscatory taxation, restric-tions on U.S. investment, or restrictions
on the ability to repatriate  assets or to convert  currency into U.S.  dollars.
There may be a greater possibility of default by foreign governments or

foreign- government-sponsored enterprises. Investments in foreign countries also
involve a risk of local political,  economic,  or social  instability,  military
action or unrest, or adverse diplomatic developments.

FOREIGN CURRENCY EXCHANGE TRANSACTIONS

     The Manager may engage in foreign currency exchange  transactions on behalf
of a Fund in order to manage currency risk. Foreign currencies will be purchased
and sold  regularly,  either in the spot (i.e.,  cash)  market or in the forward
market  (through  forward  foreign  currency  exchange  contracts,  or  "forward
contracts").

     A forward foreign currency  exchange  contract is an obligation to purchase
or sell a specific  currency at a future date,  which may be any fixed number of
days agreed upon by the parties,  commencing with the date of the contract, at a
price  set at the time of the  contract.  When the Fund  agrees to buy or sell a
security denominated in a foreign currency, it may enter into a forward contract
to "lock in" the U.S.  dollar price of the security.  By entering into a forward
contract  to buy or sell the amount of foreign  currency  involved in a security
trans-action for a fixed amount of U.S. dollars,  the Manager can protect a Fund
against possible loss resulting from adverse changes in the relationship between
the U.S.  dollar and the  foreign  currency  between  the date the  security  is
purchased or sold and the date on which  payment is made or received.  This type
of transaction is sometimes referred to as a "position hedge."

     However,  it should be noted  that  using  forward  contracts  to protect a
Fund's  foreign  investments  from  currency  fluctuations  does  not  eliminate
fluctuations  in the prices of the  underlying  securities  themselves.  Forward
contracts  simply  establish  a rate of  exchange  that can be  achieved at some
future point in time. Additionally,  although forward contracts tend to minimize
the risk of loss due to a decline in the value of the hedged currency, they also
limit any gain that might result if the hedged currency's value increases.

     Successful  use of  forward  contracts  depends on the  Manager's  skill in
analyzing and predicting currency values.  Although they are used for settlement
purposes,  forward contracts alter the Fund's exposure to currency exchange rate
activity  and could result in losses to a Fund if  currencies  do not perform as
the Manager anticipates. A Fund may also incur significant costs when converting
assets from one currency to another.

     Foreign  exchange  dealers do not  charge  fees for  currency  conversions.
Instead,  they  realize a profit  based on the  difference  (i.e.,  the  spread)
between the prices at which they are buying and selling  various  currencies.  A
dealer may offer to sell a foreign  currency  at one rate  while  simultaneously
offering a lesser rate of exchange on the purchase of that currency.

     The Funds use forward  contracts for currency hedging purposes only and not
for  speculative  purposes.  The Funds are not  required  to enter into  forward
contracts with regard to their foreign  holdings and will not do so unless it is
deemed appropriate by the Manager.

     Each  Fund's  assets are valued  daily in U.S.  dollars,  although  foreign
currency  holdings are not  physically  converted  into U.S.  dollars on a daily
basis.

DEPOSITARY RECEIPTS

     American  Depositary  Receipts and European  Depositary  Receipts (ADRs and
EDRs) are receipts  representing  ownership of shares of a foreign-based  issuer
held in trust by a bank or similar financial institution. These are designed for
U.S. and European  securities markets as alter-natives to purchasing  underlying
securities in their corresponding national markets and currencies. ADRs and EDRs
can be sponsored or unsponsored.

     Sponsored  ADRs  and  EDRs are  certificates  in which a bank or  financial
institution participates with a custodian.  Issuers of unsponsored ADRs and EDRs
are not contractually  obligated to disclose material  information in the United
States.  Therefore,  there may not be a correlation between such information and
the market value of the unsponsored ADR or EDR.

RESTRICTED SECURITIES

     Restricted  securities held by the Funds generally can be sold in privately
negotiated  transactions,  pursuant to an exemption from registration  under the
Securities Act of 1933, or in a registered public offering.  Where  registration
is  required,  a Fund may be required  to pay all or a part of the  registration
expense,  and a  considerable  period may elapse  between the time it decides to
seek registration of the securities


4                                                American Century Investments


and the  time it is  permitted  to sell  them  under an  effective  registration
statement.  If, during this period,  adverse market  conditions were to develop,
the Fund might obtain a less  favorable  price than prevailed when it decided to
try to register the securities.

SECURITIES LENDING

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

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

     If a borrower fails  financially,  there may be delays in recovering loaned
securities  and a loss in the value of collateral.  However,  loans will only be
made to parties that meet the guidelines prescribed by the Board of Directors.

PUT OPTIONS ON INDIVIDUAL SECURITIES

     Each Fund may buy puts with respect to stocks  underlying  its  convertible
security  holdings.  For example,  if the Manager  anticipates  a decline in the
price of the stock  underlying  a  convertible  security  a Fund  holds,  it may
purchase a put option on the stock. If the stock price subsequently declines, an
increase  in the value of the put option  could be  expected  to offset all or a
portion of the  effect of the  stock's  decline on the value of the  convertible
security.

FUTURES AND OPTIONS TRANSACTIONS

     FUTURES  TRANSACTIONS.  A Fund may  engage in  futures  transactions.  Such
transactions  may be  used to  maintain  cash  reserves  while  remaining  fully
invested,  to facilitate  trading,  to reduce  transaction  costs,  or to pursue
higher  investment  returns when a futures contract is priced more  attractively
than its underlying security or index.

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

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

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

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

     Those who trade  futures  contracts  may be  broadly  classified  as either
"hedgers" or "speculators."  Hedgers use the futures markets primarily to offset
unfavorable changes in the value of securities they hold or expect to


Statement of Additional Information                                         5


acquire  for  investment  purposes.  Speculators  are  less  likely  to own  the
securities  underlying  the futures  contracts they trade and are more likely to
use  futures   contracts  with  the   expectation  of  realizing   profits  from
fluctuations  in the  prices of the  underlying  securities.  The Funds will not
utilize futures contracts for speculative purposes.

     Although  techniques  other than trading  futures  contracts can be used to
control a Fund's exposure to market  fluctuations,  the use of futures contracts
may be a more  effective  means of hedging  this  exposure.  While the Funds pay
brokerage  commissions  in  connection  with  opening  and  closing  out futures
positions,  these costs are generally lower than the transaction  costs incurred
in the purchase and sale of the underlying securities.

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

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

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

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

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

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

     COMBINED  POSITIONS.  A Fund may purchase and write options in  combination
with one another, or in combination with futures or forward contracts, in


6                                                  American Century Investments


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

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

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

     CORRELATION OF PRICE CHANGES. Price changes of a Fund's futures and options
positions  may  not  be  well   correlated  with  price  changes  of  its  other
investments.  This may be because of differences  between the underlying indexes
and the types of securities  the Fund invests in. For example,  if a Fund sold a
broad-based index futures contract to hedge against a stock market decline while
completing sales of specific securities in its investment portfolio,  the prices
of the  securities  could move in a different  direction  than the broad  market
index  represented  by the  index  futures  contract.  In the case of an S&P 500
futures contract  purchased by a Fund, either in anticipation of stock purchases
or in an effort to be fully invested, failure of the contract to track the Index
accurately could hinder the Fund from achieving its investment objective.

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

     LIQUIDITY OF FUTURES CONTRACTS AND OPTIONS.  There is no assurance a liquid
secondary market will exist for any particular futures contract or option at any
particular time. Options may have relatively low trading volume and liquidity if
their strike prices are not close to the underlying  instrument's current price.
In addition,  exchanges may establish daily price fluctuation limits for futures
contracts and options and may halt trading if a contract's price moves upward or
downward  more than the limit in a given day. On volatile  trading days when the
price  fluctuation  limit is reached  or a trading  halt is  imposed,  it may be
impossible  for a Fund to  enter  into  new  positions  or  close  out  existing
positions.  If the secondary  market for a contract  were not liquid  because of
price fluctuation limits or otherwise, prompt liquidation of unfa-


Statement of Additional Information                                         7



vorable  positions  could be  difficult  or  impossible,  and the Fund  could be
required to continue holding a position until delivery or expiration  regardless
of changes in value. Under these circumstances, the Fund's access to assets held
to cover its futures and options positions also could be impaired.

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

     Each Fund may enter into futures contracts,  options, or options on futures
contracts,  provided  that such  obligations  represent  no more than 20% of the
Fund's  net  assets.  Under the  Commodity  Exchange  Act, a Fund may enter into
futures and options  transactions  for hedging  purposes  without  regard to the
percentage  of assets  committed to initial  margin and option  premiums and for
other than hedging purposes provided that assets committed to initial margin and
option  premiums  do not  exceed 5% of the  Fund's  net  assets.  To the  extent
required by law, each Fund will set aside cash and appropriate  liquid assets in
a segregated  account to cover its obligations  related to futures contracts and
options.

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

     FUTURES AND OPTIONS RELATING TO FOREIGN CURRENCIES.  Each Fund may purchase
and sell currency futures and purchase and write currency options to increase or
decrease  its  exposure  to  different  foreign  currencies.  Each Fund may also
purchase  and write  currency  options  in  conjunction  with each other or with
currency futures or forward contracts.

     Currency  futures  contracts  are  similar  to  forward  currency  exchange
contracts,   except  that  they  are  traded  on  exchanges   (and  have  margin
requirements) and have standard contract sizes and delivery dates. Most currency
futures contracts call for payment or delivery in U.S.  dollars.  The underlying
instrument of a currency option may be a foreign  cur-rency,  which generally is
purchased  or  delivered  in  exchange  for U.S.  dollars,  although it may be a
futures contract. The purchaser of a currency call obtains the right to purchase
the underlying  currency,  and the purchaser of a currency put obtains the right
to sell the underlying currency.

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

INVESTMENT RESTRICTIONS

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

     AS A FUNDAMENTAL POLICY, EACH FUND SHALL NOT:

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

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

3)   lend any security or make any other loan if, as a result,  more than 331/3%
     of the Fund's  total  assets would be lent to other  parties,  except,  (i)
     through the purchase of debt  securities in accordance  with its investment
     objective, poli-


8                                                American Century Investments


     cies and  limitations,  or (ii) by engaging in repurchase  agreements  with
     respect to portfolio securities.

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

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

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

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

8)   invest for purposes of exercising control over management.

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

     AS AN OPERATING POLICY, EACH FUND:

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

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

c)   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.

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

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

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

PORTFOLIO TRANSACTIONS

     Each Fund's assets are invested by the Manager in a manner  consistent with
the  Fund's  investment  objectives,  policies  and  restrictions  and  with any
instructions the Board of Directors may issue from


Statement of Additional Information                                         9


time to time.  Within this framework,  the Manager is responsible for making all
determinations  as to the  purchase  and sale of  portfolio  securities  and for
taking all steps necessary to implement securities transactions on behalf of the
Funds. In placing orders for the purchase and sale of portfolio securities,  the
Manager  will  use its best  efforts  to  obtain  the best  possible  price  and
execution and will otherwise place orders with broker-dealers  subject to and in
accordance with any  instructions  the Board of Directors may issue from time to
time. The Manager will select  broker-dealers to execute portfolio  transactions
on behalf of the Funds solely on the basis of best price and execution.

     The Funds' annual portfolio turnover rates are not expected to exceed 150%.
Because a higher  turnover  rate  increases  transaction  costs and may increase
taxable capital gains, the advisor  carefully  weighs the potential  benefits of
short-term investing against these considerations.

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

     Brokerage  commissions  paid by each Fund  during  the fiscal  years  ended
December 31, 1996, 1995 and 1994, are indicated in the following table.

VALUATION OF PORTFOLIO SECURITIES

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

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

PERFORMANCE

     The Funds may quote  performance  in various ways.  Historical  performance
information  will be used in advertising and sales  literature and should not be
considered an indication of future results.

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

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

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

     Total  returns  quoted in  advertising  and sales  literature  reflect  all
aspects of a Fund's return, including


10                                               American Century Investments


the effect of  reinvesting  dividends  and capital  gain  distributions  and any
change in the Fund's net asset value during the period.

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

     The Funds'  average  annual  total  returns for the  one-year,  three-year,
five-year and life-of-fund periods ended December 31, 1996, are indicated in the
following table.

                        AVERAGE ANNUAL TOTAL RETURNS

*Income & Growth Fund commenced  operations on December 17, 1990.  Equity Growth
Fund commenced operations on May 9, 1991.


     In addition to average annual total returns, each Fund may quote unaveraged
or  cumulative  total  returns  reflecting  the  simple  change  in  value of an
investment over a stated period. Average annual and cumulative total returns may
be quoted as a  percentage  or as a dollar  amount and may be  calculated  for a
single investment, a series of investments,  or a series of redemptions over any
time period.  Total  returns may be broken down into their  components of income
and capital  (including  capital  gains and changes in share  price) in order to
illustrate the  relationship of these factors and their  contributions  to total
return.

     The Funds' performance may be compared with the performance of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may  include  comparisons  with funds that,  unlike  American
Century funds,  are sold with a sales charge or deferred sales charge.  Economic
data that may be used for such comparisons may include,  but are not limited to:
U.S.  Treasury  bill,  note,  and bond yields,  money  market fund yields,  U.S.
government  debt and percentage held by foreigners,  the U.S. money supply,  net
free reserves, and yields on current-coupon GNMAs (source: Board of Governors of
the Federal  Reserve  System);  the federal  funds and discount  rates  (source:
Federal Reserve Bank of New York); yield curves for U.S. Treasury securities and
AA/AAA-rated corporate securities (source:  Bloomberg Financial Markets);  yield
curves for AAA-rated tax-free municipal  securities  (source:  Telerate);  yield
curves for foreign government  securities (sources:  Bloomberg Financial Markets
and Data Resources,  Inc.); total returns on foreign bonds (source:  J.P. Morgan
Securities Inc.);  various U.S. and foreign  government  reports;  the junk bond
market (source: Data Resources,  Inc.); the CRB Futures Index (source: Commodity
Index  Report);  the price of gold  (sources:  London  am/pm fixing and New York
Comex Spot Price);  rankings of any mutual fund or mutual fund category  tracked
by Lipper Analytical Services,  Inc. or Morningstar,  Inc.; mutual fund rankings
published in major,  nationally  distributed  periodicals;  data provided by the
Investment Company Institute;  Ibbotson  Associates,  Stocks,  Bonds, Bills, and
Inflation; major indexes of stock market performance; and indexes and historical
data supplied by major  securities  brokerage or investment  advisory firms. The
Funds may also utilize reprints from newspapers and magazines furnished by third
parties to illustrate historical performance.

     Indexes may assume  reinvestment  of dividends,  but generally  they do not
reflect  administrative  and management costs such as those incurred by a mutual
fund.

     Occasionally  statistics may be used to illustrate Fund volatility or risk.
Measures of volatility or risk  generally are used to compare a Fund's net asset
value or  performance  to a market  index.  One measure of volatility is "beta."
Beta  expresses Fund  volatility  relative to the total market as represented by
the S&P 500.


Statement of Additional Information                                        11


A beta of more than 1.00  indicates  volatility  greater than the market,  and a
beta of less than  1.00  indicates  volatility  less  than the  market.  Another
measure of volatility  or risk is "standard  deviation."  Standard  deviation is
used to measure  variability  of net asset value or total return  relative to an
average over a specified period of time. The premise is that greater  volatility
connotes greater risk undertaken to achieve desired performance.

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

TAXES

     Each Fund intends to qualify annually as a "regulated  investment  company"
under Subchapter M of the Internal Revenue Code of 1986 as amended (the "Code").
By so  qualifying,  a Fund will not be subject to federal and state income taxes
to the extent that it distributes substantially all of its net investment income
and net realized capital gains distributed to shareholders.

     Distributions  from the Funds are  taxable to  shareholders  regardless  of
whether they are taken in cash or reinvested in additional  shares.  For federal
income  tax  purposes,  shareholders  receiving  distributions  in the  form  of
additional  shares  will have a basis in each such share equal to the Fund's net
asset value per share on the reinvestment date.

     Distributions of net investment income and net short-term capital gains are
taxable  to  shareholders  as  ordinary  income.  To the  extent  that a  Fund's
dividends consist of dividend income from domestic corp-orations, such dividends
may be eligible for the dividends-received  deduction available to corporations.
Shareholders   will  be   notified   annually  of  the  federal  tax  status  of
distributions.

     Upon redeeming, selling, or exchanging shares, a shareholder will realize a
taxable gain or loss depending  upon his or her basis in the shares  liquidated.
The gain or loss  generally  will be  long-term or  short-term  depending on the
length of time the shares were held. However, a loss recognized by a shareholder
in the  disposition  of shares on which  capital  gain  dividends  were paid (or
deemed  paid)  before the  shareholder  had held his or her shares more than six
months  would be treated as a long-term  capital loss for tax  purposes.  A gain
realized on the redemption, sale, or exchange of shares would not be affected by
the  reacquisition  of shares.  A loss  realized  on the  redemption,  sale,  or
exchange of shares would be disallowed to the extent that the shares disposed of
were replaced  (whether  through  reinvestment  of  distributions  or otherwise)
within a period of 61 days beginning 30 days before and ending 30 days after the
date shares were disposed of. Under such circumstances,  the basis of the shares
acquired would be adjusted to reflect the disallowed loss.

     The information  above is only a summary of some of the tax  considerations
affecting the Funds and their shareholders;  no attempt has been made to discuss
individual tax consequences. Shareholders who are neither citizens nor residents
of the United States may be subject to a nonresident  alien  withholding  tax of
30% or a lower treaty rate,  depending on the country in which they reside.  The
Funds'  distributions  also may be subject to state,  local, or foreign taxes. A
prospective  investor  may wish to consult a tax  advisor to  determine  whether
either Fund is a suitable investment based on his or her tax situation.

ABOUT AMERICAN CENTURY QUANTITATIVE EQUITY FUNDS

     American  Century   Quantitative   Equity  Funds  (the  "Corporation")  was
organized as a California  corporation on December 31, 1987. The Corporation was
formerly known as Benham Equity Funds. The Corporation is authorized to issue 10
series  and to issue two  billion  (2,000,000,000)  shares of each such  series.
Within each  series,  the Board of Directors  may issue an  unlimited  number of
shares.  Currently,  there are five series in the Corporation,  American Century
Income  & Growth  Fund  (formerly  known as  Benham  Income & Growth  Fund)  and
American  Century  Equity  Growth Fund  (formerly  known as Benham Equity Growth
Fund) are described in this Statement of Additional Information. With respect to
each  series,  shares  issued  are  fully  paid  and  nonassessable  and have no
preemptive,  conversion,  or similar rights.  All consideration  received by the
Corporation  for shares of any  series,  and all assets,  income,  and gains (or
losses) earned thereon, belong to that series exclusively and are subject to the
liabilities related thereto.

     Shares of each series have equal voting  rights,  provided that each series
votes  separately  on matters that pertain to it  exclusively.  The  Corporation
instituted


12                                               American Century Investments


dollar-based  voting,  meaning the number of votes you are  entitled to is based
upon the dollar value of their  investment.  Under California  Corporations Code
Section 708,  shareholders  have the right to cumulate votes in the election (or
removal) of Directors.  For example, if six Directors are proposed for election,
a shareholder may cast six votes for a single candidate, or three votes for each
of two candidates, etc.

rate at which this fee is assessed is determined  monthly in a two-step process:
First,  a fee rate  schedule is applied to the assets of all of the funds of its
investment  category  managed by the Manager (the  "Investment  Category  Fee").
Second,  a  separate  fee rate  schedule  is applied to the assets of all of the
funds managed by the Manager (the "Complex  Fee").  The Investment  Category Fee
and the  Complex Fee are then added to  determine  the  unified  management  fee
payable by the Fund to the Manager.

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

Category Assets               Fee Rate
- --------------------------------------
First $1 billion               0.5200%
Next $5 billion                0.4600%
Next $15 billion               0.4160%
Next $25 billion               0.3690%
Next $50 billion               0.3420%
Next $150 billion              0.3390%
Thereafter                     0.3380%
- ----------------------------------

     The Complex Fee Schedule is as follows:

Category Assets               Fee Rate
- --------------------------------------
First $2.5 billion             0.3100%
Next $7.5 billion              0.3000%

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

     The management  agreement shall continue in effect until the earlier of the
expiration  of two  years  from the date of its  execution  or until  the  first
meeting of  shareholders  following such execution and for as long thereafter as
its  continuance  is  specifically  approved at least annually by (1) the Funds'
Board of  Directors,  or by the vote of a  majority  of  outstanding  votes  (as
defined in the Investment  Company Act) and (2) by the vote of a majority of the
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 their 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 other  clients when the Manager  believes  that
such


Statement of Additional Information                                        15


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

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

     Investment  advisory  fees paid by each Fund to the  Manager for the fiscal
years ended  December 31,  1996,  1995 and 1994 are  indicated in the  following
table. Fee amounts are net of any reimbursements  under the prior agreement with

INVESTMENT POLICIES AND TECHNIQUES

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

U.S. GOVERNMENT SECURITIES

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

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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

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

     In purchasing  securities on a when-issued or forward  commitment  basis, a
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash or appropriate  liquid assets including equity securities and
debt securities of any grade in an amount sufficient to meet the purchase price.
When the time comes to pay for the when-issued securities,  a Fund will meet its
obligations with available cash, through the sale of securities, or, although it
would not  normally  expect  to do so, by  selling  the  when-issued  securities
themselves  (which may have a market value greater or less than a Fund's payment
obligation).  Selling  securities  to meet  when-issued  or  forward  commitment
obligations may generate taxable capital gains or losses.

     On the  settlement  date,  the market  value of the security may be more or
less than its purchase or sale price under the agreement.  If the other party to
a when-issued or forward  commitment  agreement  fails to deliver or pay for the
security,  a Fund could miss a favorable price or yield  opportunity or suffer a
loss. A Fund does not earn interest on purchased securities until the settlement
date.

CONVERTIBLE SECURITIES

     Each Fund may buy securities that are convertible into common stock. Listed
below is a brief description of the various types of convertible  securities the
Funds may buy.

     CONVERTIBLE BONDS are issued with lower coupons than  nonconvertible  bonds
of the same quality and  maturity,  but they give holders the option to exchange
their bonds for a specific  number of shares of the company's  common stock at a
predetermined  price.  This  structure  allows the  convertible  bond  holder to
participate in share price movements in the company's  common stock.  The actual
return on a convertible bond may exceed its stated yield if the company's common
stock  appreciates  in value and the option to convert to common shares  becomes
more valuable.

     CONVERTIBLE  PREFERRED  STOCKS are nonvoting  equity  securities that pay a
fixed  dividend.   These  securities  have  a  convertible  feature  similar  to
convertible  bonds;  however,  they do not have a  maturity  date.  Due to their
fixed-income  features,  convertible  issues  typically  are more  sensitive  to
interest  rate  changes  than  the  underlying  common  stock.  In the  event of
liquidation,  bondholders would have claims on company assets senior to those of
stockholders;

2                                                   American Century Investments


preferred   stockholders   would   have   claims   senior  to  those  of  common
stockholders.

     WARRANTS  entitle the holder to buy the issuer's  stock at a specific price
for a specific  period of time. The price of a warrant tends to be more volatile
than, and does not always track, the price of the underlying stock. Warrants are
issued with expiration  dates.  Once a warrant  expires,  it has no value in the
market.

REPURCHASE AGREEMENTS

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

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

     The  Funds  have  received  permission  from the  Securities  and  Exchange
Commission (SEC) to participate in joint repurchase agreements collateralized by
U.S. government securities with other mutual funds advised by the Manager. Joint
repos  are  expected  to  increase  the  income  the  Funds  can earn  from repo
transactions without increasing the risks associated with these transactions.

FOREIGN SECURITIES

     The Funds may buy securities of foreign  issuers in foreign  markets.  With
respect to the Global Gold and Utilities Funds, most of their foreign securities
investments  are  made by  purchasing  American  Depositary  Receipts  ("ADR"s),
"ordinary  shares," or "New York shares."  Please refer to the discussion  under
"Depositary   Receipts"   on  page  5.  The   Utilities   Fund  may   invest  in
foreign-currency-denominated  debt or equity  securities of companies engaged in
the  utilities  industry that trade in foreign  markets if the Manager  believes
that such investments will be advantageous to the Fund.

     Investing in foreign  companies may involve risks not typically  associated
with investing in U.S. companies. The value of securities denominated in foreign
currencies and of dividends from such securities can change  significantly  when
foreign  currencies  strengthen or weaken relative to the U.S.  dollar.  Foreign
securities  markets  generally  have less trading volume and less liquidity than
U.S. markets, and prices in some foreign markets can be very volatile.

     Many foreign  countries lack uniform  accounting  and disclosure  standards
comparable to those that apply to U.S.  companies,  and it may be more difficult
to obtain reliable information  regarding a foreign issuer's financial condition
and  operations.  In  addition,  the  costs  of  foreign  investing,   including
withholding  taxes,  brokerage  commissions,  and custodial  fees, are generally
higher than for U.S. investments.

     Foreign markets may offer less  protection to investors than U.S.  markets.
Foreign  issuers,  brokers,  and  securities  markets  may be  subject  to  less
governmental  supervision.  Foreign security trading practices,  including those
involving  the  release of assets in advance of payment,  may involve  increased
risks in the event of a failed trade or the  insolvency of a  broker-dealer  and
may involve substantial delays. It may also be difficult to enforce legal rights
in foreign countries.

     Investing  abroad carries  political and economic risks distinct from those
associated  with  investing in the United  States.  Foreign  investments  may be
affected by actions of foreign  governments that are adverse to the interests of
U.S. investors, including the possibility of expropriation or nationalization of
assets, confiscatory taxation, restrictions on U.S. investment, or

Statement of Additional Information                                            3


restrictions  on the ability to  repatriate  assets or to convert  currency into
U.S.  dollars.  There  may  be a  greater  possibility  of  default  by  foreign
governments or foreign-government-sponsored  enterprises. Investments in foreign
countries  also  involve  a  risk  of  local  political,   economic,  or  social
instability, military action or unrest, or adverse diplomatic developments.

     Each  Fund's  assets are valued  daily in U.S.  dollars,  although  foreign
currency  holdings are not  physically  converted  into U.S.  dollars on a daily
basis.

FOREIGN CURRENCY EXCHANGE TRANSACTIONS

     The Manager may engage in foreign currency exchange  transactions on behalf
of a Fund in order to manage currency risk. Foreign currencies will be purchased
and sold  regularly,  either in the spot (i.e.,  cash)  market or in the forward
market  (through  forward  foreign  currency  exchange  contracts,  or  "forward
contracts").

     A forward foreign currency  exchange  contract is an obligation to purchase
or sell a specific  currency at a future date,  which may be any fixed number of
days agreed upon by the parties,  commencing with the date of the contract, at a
price  set at the  time of the  contract.  When a Fund  agrees  to buy or sell a
security denominated in a foreign currency, it may enter into a forward contract
to "lock in" the U.S.  dollar price of the security.  By entering into a forward
contract  to  buy or  sell  the  amount  of  foreign  currency  involved  in the
underlying  securities  transaction  for a fixed  amount  of U.S.  dollars,  the
Manager  can  protect a Fund  against a possible  loss  resulting  from  adverse
changes in the  relationship  between the U.S.  dollar and the foreign  currency
between the date the  security is purchased or sold and the date payment is made
or received.  This type of transaction  is sometimes  referred to as a "position
hedge."

     However,  it should be noted  that  using  forward  contracts  to protect a
Fund's  foreign  investments  from  currency  fluctuations  does  not  eliminate
fluctuations  in the prices of the  underlying  securities  themselves.  Forward
contracts  simply  establish  a rate of  exchange  that can be  achieved at some
future point in time. Additionally,  although forward contracts tend to minimize
the risk of loss due to a decline in the value of the hedged currency, they also
limit  any gain  that  might  result  if the  hedged  currency's  value  were to
increase.

     Successful  use of  forward  contracts  depends on the  Manager's  skill in
analyzing and predicting currency values.  Although they are used for settlement
purposes,  forward  contracts alter a Fund's exposure to currency  exchange rate
activity  and could result in losses to a Fund if  currencies  do not perform as
the Manager anticipates. A Fund may also incur significant costs when converting
assets from one currency to another.

     Foreign  exchange  dealers do not  charge  fees for  currency  conversions.
Instead,  they  realize a profit  based on the  difference  (i.e.,  the  spread)
between the prices at which they are buying and selling  various  currencies.  A
dealer may offer to sell a foreign  currency  at one rate  while  simultaneously
offering a lesser rate of exchange on the purchase of that currency.

     The Funds use forward  contracts for currency hedging purposes only and not
for  speculative  purposes.  The Funds are not  required  to enter into  forward
contracts  with  regard  to  foreign  holdings  and will not do so  unless  this
procedure is deemed appropriate by the Manager.

     The currency management  techniques  discussed above are limited by various
constraints, including the intention to protect the U.S. tax status of each Fund
as a regulated investment company.

NON-SECTOR EQUITY SECURITIES (GLOBAL NATURAL RESOURCES)

     Global  Natural  Resources  may invest in companies  engaged in the natural
resources  industry  that do not meet all of the criteria  for  inclusion in the
Energy and Basic Materials  sectors  (excluding  chemical  companies) of the Dow
Jones World Stock Index.  These may include small companies that do not meet the
capitalization  requirement  for  inclusion  in the Energy  and Basic  Materials
sectors  ("Sectors")  but  that  the  Manager  believes  represent   significant
investment opportunities for the Fund.

     Within this category,  the Manager attempts to select securities of issuers
whose  revenues and earnings  are  expected to be  influenced  by changes in the
prices of natural  resources  and that are  expected to perform in a manner that
causes the Fund's performance to closely track the performance of the Sectors.

DEPOSITARY RECEIPTS

     American  Depositary  Receipts  ("ADR"s) and European  Depositary  Receipts
("EDR"s) are receipts representing ownership of shares of a foreign-based issuer
held in trust by a bank or similar financial institution. These are designed for
U.S. and European  securities  markets as alternatives to purchasing  underlying
securities in their corresponding national markets and currencies. ADRs and EDRs
can be sponsored or unsponsored.

     Sponsored  ADRs  and  EDRs are  certificates  in which a bank or  financial
institution participates with a custodian.  Issuers of unsponsored ADRs and EDRs
are not contractually  obligated to disclose material  information in the United
States.  Therefore,  there may not be a correlation between such information and
the market value of the unsponsored ADR or EDR.

     ADRs  are   dollar-denominated   receipts  representing  interests  in  the
securities  of a foreign  issuer.  They are  issued by U.S.  banks and traded on
exchanges or over the counter in the United States.  Ordinary  shares are shares
of foreign  issuers  that are traded  abroad  and on a U.S.  exchange.  New York
shares are shares that a foreign  issuer has allocated for trading in the United
States. ADRs, ordinary shares, and New York shares all may be purchased with and
sold for U.S. dollars, which protects the Fund from the foreign settlement risks
described under the section titled "Foreign Securities" on page 3.

RESTRICTED SECURITIES

     Restricted  securities held by the Funds generally can be sold in privately
negotiated  transactions,  pursuant to an exemption from registration  under the
Securities Act of 1933, or in a registered public offering.  Where  registration
is required,  the Funds may be required to pay all or a part of the registration
expense,  and a  considerable  period may elapse  between the time it decides to
seek  registration  of the  securities and the time it is permitted to sell them
under an effective  registration  statement.  If,  during this  period,  adverse
market  conditions  were to develop,  a Fund might obtain a less favorable price
than prevailed when it decided to try to register the securities.

SECURITIES LENDING

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

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

SHORT SALES AND PUT OPTIONS ON INDIVIDUAL SECURITIES (UTILITIES FUND)

     The Utilities  Fund may buy puts and enter into short sales with respect to
stocks underlying its convertible security holdings. For example, if the advisor
anticipates  a  decline  in the  price of the  stock  underlying  a  convertible
security  the Fund holds,  it may purchase a put option on the stock or sell the
stock short. If the stock price subsequently declines, the proceeds of the short
sale or an increase  in the value of the put option  could be expected to offset
all or a  portion  of the  effect  of the  stock's  decline  on the value of the
convertible security.

     When the Fund enters  into a short  sale,  it will be required to set aside
securities  equivalent  in kind and amount to those  sold  short (or  securities
convertible  or  exchangeable  into such  securities)  and will be  required  to
continue to hold them while the short sale is  outstanding.  The Fund will incur
transaction  costs,  including  interest  expenses,  in connection with opening,
maintaining, and closing short sales.

FUTURES AND OPTIONS TRANSACTIONS

     FUTURES  TRANSACTIONS.  A Fund may  engage in  futures  transactions.  Such
transactions  may be  used to  maintain  cash  reserves  while  remaining  fully
invested,  to facilitate  trading,  to reduce  transaction  costs,  or to pursue
higher  investment  returns when a futures contract is priced more  attractively
than its underlying security or index.

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

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

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

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

     Some futures  contract  strategies carry a substantial risk of loss, due to
both the low margin deposits  required and the high degree of leverage  involved
in futures pricing. A relatively small movement in a futures contract may result
in immediate, substantial gains or losses to a Fund.

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

     Although  techniques  other than trading  futures  contracts can be used to
control a Fund's exposure to market  fluctuations,  the use of futures contracts
may be a more  effective  means of  hedging  this  exposure.  While a Fund  pays
brokerage  commissions  in  connection  with  opening  and  closing  out futures
positions,  these costs are generally lower than the transaction  costs incurred
in the purchase and sale of the underlying securities.

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

     The buyer of a typical  put option can expect to realize a gain if security
prices fall substantially.  However,  if the underlying  instrument's price does
not fall enough to offset the cost of purchasing the

6                                                   American Century Investments


option,  a put buyer can expect to suffer a loss  (limited  to the amount of the
premium paid plus related transaction costs).

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

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

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

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

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

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

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

Statement of Additional Information                                            7


Purchasing  an  option  on a futures  contract  does not  require a Fund to make
margin payments unless the option is exercised.

     CORRELATION OF PRICE  CHANGES.  Because there are a limited number of types
of  exchange-traded  options  and  futures  contracts,  it is  likely  that  the
standardized  contracts available will not match a Fund's current or anticipated
investments exactly. A Fund may invest in options and futures contracts based on
securities with issuers,  maturities,  or other  characteristics  different from
those of the securities in which it typically invests (for example, it may hedge
intermediate-term  securities  with a  futures  contract  based  on an  index of
long-term  bond prices or hedge  stock  holdings  with  futures  contracts  on a
broad-based  stock index such as the Standard & Poor's 500 Composite Stock Price
Index (S&P 500)) which involves a risk that the options or futures position will
not track the performance of the Fund's other investments.

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

     RISKS AND LIQUIDITY OF FUTURES  CONTRACTS AND OPTIONS.  Futures and options
have risks associated with their use: possible default by the other party to the
transaction;  illiquidity;  and, to the extent the Manager's  interpretation  of
certain  market  movements  is  incorrect,   the  risk  that  the  use  of  such
transactions  could  result in losses  greater  than if they had not been  used.
Losses resulting from the use of these transactions would reduce net asset value
and possibly income.

     There  is no  assurance  a  liquid  secondary  market  will  exist  for any
particular  futures contract or option at any particular time.  Options may have
relatively low trading volume and liquidity if their strike prices are not close
to the  underlying  instrument's  current  price.  In  addition,  exchanges  may
establish daily price  fluctuation  limits for futures contracts and options and
may halt trading if a  contract's  price  increases  or decreases  more than the
limit on a given day. On volatile trading days when the price  fluctuation limit
is reached or a trading  halt is  imposed,  it may be  impossible  for a Fund to
enter into new  positions  or close out  existing  positions.  If the  secondary
market for a contract were not liquid,  because of price  fluctuation  limits or
otherwise,  prompt  liquidation of unfavorable  positions  could be difficult or
impossible,  and the Fund could be required to continue holding a position until
delivery or expiration regardless of changes in the value of the position. Under
these  circumstances,  the Fund's  access to assets held to cover its future and
options positions also could be impaired.

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

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

8                                                   American Century Investments


     The Utilities Fund may enter into futures contracts, options, or options on
futures contracts,  provided that such obligations represent no more than 20% of
its net assets.

     Each Fund may enter into futures  transactions  (including related options)
for hedging  purposes  without regard to the  percentage of assets  committed to
initial  margin  and for  other  than  hedging  purposes  provided  that  assets
committed to initial margin deposits on such instruments, plus premiums paid for
open futures options positions,  less the amount by which any such positions are
"in-the-money,"  do not exceed 5% of its total assets. To the extent required by
law, Global Natural Resources will set aside cash and appropriate  liquid assets
in a segregated  account to cover its obligations  related to futures  contracts
and options. Financial futures or options purchased or sold will be standardized
and traded through the facilities of a U.S. or foreign securities association or
listed on a U.S. or foreign securities or commodities exchange,  board of trade,
or similar entity, or quoted on an automatic  quotation  system,  except that it
may effect transactions in over-the-counter options with primary U.S. government
securities  dealers  recognized  by the  Federal  Reserve  Bank of New York.  In
addition,  Global Natural  Resources has undertaken to limit aggregate  premiums
paid on all options purchased to no more than 5% of its total net asset value.

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

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

     Currency  futures  contracts  are  similar  to  forward  currency  exchange
contracts,   except  that  they  are  traded  on  exchanges   (and  have  margin
requirements) and have standard contract sizes and delivery dates. Most currency
futures contracts call for payment or delivery in U.S.  dollars.  The underlying
instrument of a currency  option may be a foreign  currency,  which generally is
purchased  or  delivered  in  exchange  for U.S.  dollars,  although it may be a
futures contract. The purchaser of a currency call obtains the right to purchase
the underlying  currency,  and the purchaser of a currency put obtains the right
to sell the underlying currency.

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

     GOLD FUTURES  CONTRACTS.  Pursuant to a 1988  undertaking with the State of
California, Global Gold's combined margin deposits on gold futures contracts may
not exceed 5% of its net  assets.  The extent to which  Global  Gold enters into
gold futures  contracts (and forward foreign currency  transactions) may also be
limited  by the fact that the Fund  intends  to meet  Internal  Revenue  Service
requirements for  qualification  as a regulated  investment  company,  including
requirements  regarding  diversification  of assets and  qualifying  income.  To
assure that Global Gold's  investments in gold futures  contracts do not involve
leveraging, cash or cash equivalents equal to the underlying commodity value (at
the time a contract is executed) of any gold futures  contract  purchased by the
Fund (less related margin  deposits)  will be deposited in a segregated  account
with its custodian.

INDEXED SECURITIES (GLOBAL NATURAL RESOURCES)

     Global Natural  Resources may invest in indexed  securities  whose value is
linked to commodities, including, but not limited to, notes indexed to the

Statement of Additional Information                                            9


Goldman  Sachs  Commodity  Index  (GSCI).   The  GSCI  is  composed  of  energy,
agricultural,  livestock,  and metals commodities.  The Fund may invest in notes
indexed to the entire GSCI or to certain components of the GSCI.

     A  commodity-linked  note  enables  the  investor  to purchase a note whose
coupons  or  redemption  value is  linked  to the  performance  of a  particular
commodity  price.  The  Fund  may  purchase  and  sell  indexed  securities  for
investment  purposes  as well as hedging  purposes  to the extent  permitted  by
applicable law. Indexed  securities may have return  characteristics  similar to
direct investments in the underlying  commodity or to one or more options on the
underlying  commodity.   Indexed  securities  may  be  more  volatile  than  the
underlying  commodity  itself and present many of the same risks as investing in
futures  and  options.  Indexed  securities  are also  subject  to credit  risks
associated with the issuer of the security.

     The Fund may invest in  indexed  securities  to track the  Sectors at lower
transaction  costs  or  to  take  advantage  of  investment   opportunities  not
represented by the Sectors.

GOLD INVESTMENTS (GLOBAL GOLD)

     GOLD  BULLION.  As a means of seeking its  principal  objective  of capital
appreciation  and when it is felt to be  appropriate as a possible hedge against
inflation,  Global  Gold may invest a portion of its assets in gold  bullion and
may hold a portion of its cash in foreign  currency  in the form of gold  coins.
There is, of course,  no assurance that such  investments  will provide  capital
appreciation as a hedge against inflation.  The Fund's ability to invest in gold
bullion is restricted by the  diversification  requirements  which the Fund must
meet in order to qualify as a regulated investment company under Subchapter M of
the Internal  Revenue  Code of 1986,  as amended  (the  "Code"),  as well as the
diversification  requirements of the Investment  Company Act of 1940, as amended
(the "1940 Act"). In addition,  the ability of the Fund to make such investments
may be further  restricted by the securities laws and regulations in effect from
time to time in the states where the Fund's shares are  qualified for sale.  The
Fund has not previously  invested in gold bullion because of these  regulations.
However,  at the date of this Statement of Additional  Information  there do not
appear to be any regulations currently in effect in the states in which the Fund
is qualified for sale  prohibiting  such  purchases.  Accordingly,  if otherwise
consistent with the Fund's objectives, it may purchase gold bullion.

     Fund assets will be invested in gold bullion at such times as the prospects
of such investments are, in the opinion of management, attractive in relation to
other  possible  investments.  The basic trading unit for gold bullion is a gold
bar weighing  approximately  100 troy ounces with a purity of at least 995/1000,
although gold bullion is also sold in much smaller  units.  Gold bars and wafers
are usually numbered and bear an indication of purity and the stamp of the assay
office which certifies the bar's purity. Bars of gold bullion  historically have
traded  primarily in New York,  London,  and Zurich gold markets and in terms of
volume,  such gold  markets  have been the major  markets  for  trading  in gold
bullion.  Prices in the Zurich gold market generally correspond to the prices in
the London gold market.  Since the ownership of gold bullion became legal in the
United States on December 31, 1974,  U.S.  markets for trading gold bullion have
developed. It is anticipated that transactions in gold will generally be made in
such U.S.  markets,  although such  transactions  may be made in foreign markets
when it is deemed to be in the best interest of the Fund.  Transactions  in gold
bullion by the Fund are negotiated with principal  bullion dealers,  unless,  in
the investment's  manager's opinion,  more favorable prices (including the costs
and expenses  described  below) are otherwise  obtainable.  Prices at which gold
bullion is purchased or sold include dealer  mark-ups or  mark-downs,  insurance
expenses,  may be a greater or lesser percentage of the price from time to time,
depending on whether the price of gold bullion  decreases  or  increases.  Since
gold bullion does not generate any investment  income, the only source of return
to the Fund on such an investment will be from any gains realized upon its sale,
and negative  return will be realized,  of course,  to the extent the Fund sells
its gold bullion at a loss.

SPECIAL CONSIDERATIONS REGARDING GLOBAL GOLD'S
INVESTMENT POLICIES

     As is the case with respect to virtually all  investments,  there are risks
inherent in Global  Gold's  policies of  investing  in  securities  of companies
engaged in mining, processing or dealing in gold or other precious metals and in
gold bullion.  In addition to the general  considerations  described above, such
investments may involve the following special considerations:

     FLUCTUATIONS  IN THE  PRICE OF GOLD.  The price of gold has  recently  been
subject to substantial  upward and downward movements over short periods of time
and may be  affected  by  unpredictable  international  monetary  and  political
policies,  such as currency  devaluations or revaluations,  economic  conditions
within an individual country, trade imbalances or trade or currency restrictions
between  countries and world inflation  rates and interest  rates.  The price of
gold,  in turn, is likely to affect the market prices of securities of companies
mining, processing, or dealing in gold and, accordingly, the value of the Fund's
investments in such securities also may be affected.

     POTENTIAL EFFECT OF CONCENTRATION OF SOURCE OF SUPPLY AND CONTROL OF SALES.
At the current time there are only four major  sources of supply of primary gold
production,  and the market share of each source cannot be readily  ascertained.
One of the  largest  national  producers  of gold  bullion  and  platinum is the
Republic of South Africa. Changes in political and economic conditions affecting
South Africa may have a direct impact on its sales of gold.  Under South African
law, the only  authorized  sales agent for gold  produced in South Africa is the
Reserve Bank of South Africa which, through its retention policies, controls the
time and place of its retention policies, and controls the time and place of any
sale of South African  bullion.  The South African  Ministry of Mines determines
gold mining  policy.  South Africa depends  predominantly  on gold sales for the
foreign  exchange  necessary  to finance its  imports,  and its sales  policy is
necessarily  subject  to  national  and  international  economic  and  political
developments.

     TAX AND CURRENCY  LAWS.  Changes in the tax or currency  laws of the United
States,  and of foreign  countries,  may inhibit the Fund's ability to pursue or
may increase  the cost of pursuing  its  investment  programs.  For example,  in
September  1985,  the government of South Africa  reimposed a two-tier  currency
system.  While this system may be removed  within the next  couple of years,  it
continues to  differentiate  between  currency which may be used in transactions
involving  transfers of South  African  investments  by foreign  investors  (the
"financial  rand") and currency used for importing  goods and remitting  profits
and dividends from an operating  enterprise ( the "commercial rand").  Since the
reimposition of the two-tier  currency  system,  the volatility of the financial
rand has contributed to  fluctuations in the net asset value of the Fund.  These
effects may increase if the permissible uses of the financial rand are expanded.

     UNPREDICTABLE  MONETARY POLICIES,  ECONOMIC AND POLITICAL  CONDITIONS.  The
Fund's  assets  might be less  liquid or the  change in the value of its  assets
might be more volatile (and less related to general price  movements in the U.S.
markets)  than would be the case with  investments  in the  securities of larger
U.S. companies, particularly because the price of gold and other precious metals
may be affected by unpredictable  international  monetary  policies and economic
and political  considerations,  governmental  controls,  conditions of scarcity,
surplus or speculation.  In addition,  the use of gold or Special Drawing Rights
(which  are  also  used  by  members  of the  International  Monetary  Fund  for
international  settlements)  to settle net deficits  and  surpluses in trade and
capital movements  between nations subject the supply and demand,  and therefore
the price,  of gold to a variety of economic  factors which  normally  would not
affect other types of commodities.

     NEW AND  DEVELOPING  MARKETS FOR PRIVATE GOLD  OWNERSHIP.  Between 1933 and
December  31,  1974,  a market did not exist in the United  States in which gold
bullion could be purchased by  individuals  for  investment  purposes.  Since it
became legal to invest in gold, markets have developed in the United States. Any
large  purchases or sales of gold  bullion  could have an effect on the price of
gold bullion.  Recently, several Central Banks have been sellers of gold bullion
from their reserves. Sales by central banks and/or rumors of such sales have had
a negative effect on gold prices.

     EXPERTISE OF THE  INVESTMENT  MANAGER.  The  successful  management  of the
Fund's  portfolio  may be more  dependent  upon the skills and  expertise of its
investment manager than is the case for most mutual funds because of the need to
evaluate the factors identified above. Moreover, in some countries,  disclosures
concerning an issuer's financial  condition and results and other matters may be
subject to less stringent regulatory  provisions,  or may be presented on a less
uniform  basis than is the case for  issuers  subject to U.S.  securities  laws.
Issuers  and  securities  exchanges  in some  countries  may be  subject to less
stringent governmental regulations than is the case for U.S. companies.

RISK FACTORS (UTILITIES FUND)

     Because  the  Utilities  Fund  concentrates  its  assets  in the  utilities
industry,  its performance  depends in part on how favorably  investors perceive
this sector of the market relative to other sectors (such as  transportation  or
technology).  Of course,  investor  perceptions  of the  utilities  industry are
driven not only by  comparisons  with  other  market  sectors  but by trends and
events within the utilities  industry.  The following is a brief outline of risk
factors associated with investment in the utilities industry.

     REGULATORY  RISKS.  Regulators  (primarily at the state level)  monitor and
control public utility company revenues and costs.  Regulators can limit profits
and dividends  paid to investors;  they may also restrict a company's  access to
new  markets.   Some  analysts   observe  that  state   regulators  have  become
increasingly  active in  developing  and  promoting  energy  policy  through the
regulatory process.

     NATURAL RESOURCE RISKS.  Swift and  unpredictable  changes in the price and
supply of natural  resources can hamper  utility  company  profitability.  These
changes may be caused by political events,  energy  conservation  programs,  the
success of exploration projects, or tax and other regulatory policies of various
governments.

     ENVIRONMENTAL   RISKS.   There  are  considerable   costs  associated  with
environmental  compliance,  nuclear waste cleanup,  and safety  regulation.  For
example,  coal-burning utilities are under pressure to curtail sulfur emissions,
and  utilities in general  increasingly  are called upon by  regulators  to bear
environmental costs, which may not be easily recovered through rate increases or
business growth.

     Changing weather patterns and natural  disasters affect consumer demand for
utility  services (e.g.,  electricity,  heat, and air  conditioning),  which, in
turn, affects utility revenues.

     TECHNOLOGY AND  COMPETITIVE  RISKS.  The  introduction  and phase-in of new
technologies can affect a utility company's  competitive  strength.  The race by
long-distance  telephone  providers to incorporate fiber optic technology is one
example of competitive risk within the utilities industry.

     The increasing role of independent power producers  ("IPP"s) in the natural
gas and electric utility  segments of the utilities  industry is another example
of  competitive  risk.  Typically,  IPPs wholesale  power to  established  local
providers,  but there is a trend  toward  letting  them sell power  directly  to
industrial  consumers.  Co-generation  facilities,  such as  those  of  landfill
operators that produce  methane gas as a byproduct of their core business,  pose
another  competitive  challenge  to gas and electric  utilities.  In addition to
offering a less  expensive  source of power,  these  companies  may receive more
favorable  regulatory treatment than utilities seeking to expand facilities that
consume nonrenewable energy sources.

     INTEREST RATE RISKS. Utility companies usually finance capital expenditures
(e.g.,  new plant  construction)  by issuing  long-term debt.  Rising  long-term
interest rates increase interest expenses and reduce company earnings.

INVESTMENT RESTRICTIONS

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

     AS A FUNDAMENTAL POLICY, EACH FUND SHALL NOT:

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

     2)  borrow  money,  except that the Fund may borrow money for  temporary or
emergency  purposes  (not  for  leveraging  or  investment)  in  an  amount  not
exceeding 33 1/3% of the Fund's

12                                                  American Century Investments


total  assets  (including  the amount  borrowed)  less  liabilities  (other than
borrowings).

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

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

     5) deviate from its policy of  concentrating  its investments in securities
of  issuers  engaged in mining,  fabricating,  processing  or dealing in gold or
other  precious  metals,  such as silver,  platinum and  palladium  [Global Gold
only]; engaged in the utilities industry [Utilities Fund only] or engaged in the
natural resources industries [Global Natural Resources only].

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

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

         (b) [Global  Gold only]  purchase  gold  bullion,  gold coins,  or gold
represented  by  certificates  of ownership  interest or gold futures  contracts
whose underlying  commodity value would cause the Fund's aggregate investment in
such commodities to exceed 10% of the Fund's net assets.

     8)  invest for purposes of exercising control over management.

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

     AS AN OPERATING POLICY, EACH FUND:

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

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

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

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

Statement of Additional Information                                           13


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

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

PORTFOLIO TRANSACTIONS

     Each Fund's assets are invested by the Manager in a manner  consistent with
the  Fund's  investment  objectives,  policies,  and  restrictions  and with any
instructions  the Board of  Directors  may issue from time to time.  Within this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement securities  transactions on behalf of each Fund. In placing orders for
the  purchase and sale of  portfolio  securities,  the Manager will use its best
efforts to obtain the best possible price and execution and otherwise will place
orders with  broker-dealers  subject to and in accordance with any  instructions
from the Board of Directors.  The Manager will select  broker-dealers to execute
portfolio  transactions on behalf of each Fund solely on the basis of best price
and execution.

     Global Gold, Global Natural Resources and Utilities Funds' annual portfolio
turnover  rates are not  expected to exceed 100%,  100% and 150%,  respectively.
Because a higher  turnover  rate  increases  transaction  costs and may increase
taxable capital gains, the Manager  carefully  weighs the potential  benefits of
short-term investing against these considerations.

     The  portfolio  turnover  rates for the Funds are  listed in the  Financial
Highlights in the prospectus.

     Brokerage  commissions  paid by the Funds  during  the fiscal  years  ended
December 31, 1996, 1995 and 1994, are indicated in the following table.

VALUATION OF PORTFOLIO SECURITIES

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

     The  Manager  typically  completes  its  trading  on behalf of the Funds in
various markets before the Exchange closes for the day. Securities are priced at
market value,  depending upon the market or exchange on which they trade.  Price
quotations for  exchange-listed  securities are taken from the primary exchanges
on which these securities  trade.  Securities traded on exchanges will be valued
at their last sale prices.  If no sale is reported,  the mean between the latest
bid and asked prices is used. Securities traded  over-the-counter will be valued
at the mean between the latest bid and asked prices. Fixed-income securities are
priced at market value on the basis of market quotations supplied by independent
pricing  services.  Foreign currency exchange rates are also determined prior to
the close of the Exchange. Trading of securities in foreign markets may not take
place every day the Exchange is open, and trading takes place in various foreign
markets on days on which the  Exchange  and the Funds'  offices are not open and
the Funds' net asset values are not calculated.  A Fund's net asset value may be
significantly  affected on days when  shareholders  have no access to the Funds.
Securities for which market quotations are not readily  available,  or which may
change in value due to events occurring

14                                                  American Century Investments


after their  primary  exchange has closed for the day, are valued at fair market
value as determined in good faith under the direction of the Board of Directors.

PERFORMANCE

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

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

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

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

     For the 30-day period ended December 31, 1996,  the Utilities  Fund's yield
was 3.66%.

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

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

     The Funds'  average  annual  total  returns for the  one-year,  three-year,
five-year and life-of-fund periods ended December 31, 1996, are indicated in the
table below.

     Average  annual  total  returns  for  periods  of less  than  one  year are
calculated by  determining a Fund's total return for the period,  extending that
return for a full year (assuming that performance  remains  constant  throughout
the year),  and quoting the result as an annual return.  Because a Fund's return
may not remain  constant over the course of a year,  these  performance  figures
should be viewed as strictly hypothetical.

     In addition to average annual  returns,  the Funds may quote  unaveraged or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Average annual and cumulative total returns may be quoted
as a  percentage  or as a  dollar  amount  and may be  calculated  for a  single
investment,  a series of investments,  or a series of redemptions  over any time
period.  Total  returns may be broken down into their  components  of income and
capital  (including  capital  gains  and  changes  in share  price)  in order to
illustrate the  relationship of these factors and their  contributions  to total
return.  Performance information may be quoted numerically or in a table, graph,
or similar illustration.

     A Fund's  performance  may be compared with the performance of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may  include  comparisons  with funds that,  unlike  American
Century funds, are sold

Statement of Additional Information                                           15


with a sales charge or deferred sales charge.  Sources of economic data that may
be considered in making such  comparisons  may include,  but are not limited to:
U.S.  Treasury  bill,  note,  and bond yields,  money  market fund yields,  U.S.
government  debt and percentage held by foreigners,  the U.S. money supply,  net
free  reserves,  and  yields  on  current-coupon  Government  National  Mortgage
Association  securities  (GNMAs)  (source:  Board of  Governors  of the  Federal
Reserve System);  the federal funds and discount rates (source:  Federal Reserve
Bank of New York);  yield curves for U.S.  Treasury  securities and AA/AAA-rated
corporate  securities (source:  Bloomberg  Financial Markets);  yield curves for
AAA-rated tax-free municipal  securities  (source:  Telerate);  yield curves for
foreign government  securities  (sources:  Bloomberg  Financial Markets and Data
Resources, Inc.); total returns on foreign bonds (source: J.P. Morgan Securities
Inc.);  various  U.S.  and  foreign  government  reports;  the junk bond  market
(source: Data Resources,  Inc.); the CRB Futures Index (source:  Commodity Index
Report); the price of gold (sources:  London a.m./p.m. fixing and New York Comex
Spot  Price);  rankings of any mutual fund or mutual  fund  category  tracked by
Lipper  Analytical  Services,  Inc. or Morningstar,  Inc.;  mutual fund rankings
published in major,  nationally  distributed  periodicals;  data provided by the
Investment Company Institute;  Ibbotson  Associates,  Stocks,  Bonds, Bills, and
Inflation; major indexes of stock market performance; and indexes and historical
data supplied by major  securities  brokerage or investment  advisory firms. The
Funds may also utilize reprints from newspapers and magazines furnished by third
parties to illustrate historical performance.

     Global Gold's sales  literature  may  illustrate the market for gold within
the  context  of   historical   and  current   economic   conditions.   Specific
illustrations  may include the  relationship of the price of gold (per London pm
fixing) to 30-year U.S. Treasury bond yields, 30-year U.S. Treasury bond prices,
inflation  as measured by the  Consumer  Price Index,  or equity  securities  as
measured by the Standard & Poor's 500  Composite  Stock Price Index (S&P 500) or
the Dow Jones Industrial Average.

     Indexes may assume  reinvestment  of dividends,  but generally  they do not
reflect  administrative  and management costs such as those incurred by a mutual
fund.

     Statistics  may be used in advertising  and sales  literature to illustrate
historical and projected demand for commodities  owned or processed by companies
in which Global Natural Resources invests.  This may include  illustrations such
as a chart that shows  historical  and  projected  demand  for  multiple  energy
sources measured in barrels of oil equivalents, or "BOEs."

     Occasionally, statistics may be used to illustrate Fund volatility or risk.
Measures of volatility or risk are generally  used to compare a Fund's net asset
value or  performance  to a market  index.  One measure of volatility is "beta."
Beta  expresses Fund  volatility  relative to the total market as represented by
the S&P 500. A beta of more than 1.00 indicates  volatility greater than that of
the  market,  and a beta of less than 1.00  indicates  volatility  less than the
market.  Another measure of volatility or risk is "standard deviation." Standard
deviation is used to measure the  variability of net asset value or total return
relative  to an average  over a  specified  period of time.  The premise is that
greater  volatility  connotes  greater  risk  undertaken  to  achieve  a desired
performance.

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

     The Manager may obtain  ratings  from one or more rating  agencies  and may
publish such ratings in advertisements and sales literature.

TAXES

     Each Fund intends to qualify each year as a "regulated  investment company"
under  Subchapter  M of the  Internal  Revenue  Code of 1986,  as  amended  (the
"Code").  By so qualifying,  a Fund will not incur federal or state income taxes
on its net  investment  income and net realized  capital  gains  distributed  to
shareholders.

     Distributions  from the Funds are  taxable to  shareholders  regardless  of
whether they are taken in cash or reinvested in additional  shares.  For federal
income  tax  purposes,  shareholders  receiving  distributions  in the  form  of
additional  shares  will have a basis in each such  share  equal to a Fund's net
asset value per share on the reinvestment date.

16                                                  American Century Investments


     Distributions of net investment income and net short-term capital gains are
taxable to  shareholders  as ordinary  income.  With respect to Global Gold, the
Board of Directors does not expect to declare  dividends on a regular basis.  To
the extent  that a Fund's  dividends  consist of dividend  income from  domestic
corporations,   such  dividends  may  be  eligible  for  the  dividends-received
deduction  available to corporations.  Shareholders will be notified annually of
the federal tax status of distributions.

     As of December 31,  1996,  Utilities  Fund had a capital loss  carryover of
$194,348  that will expire on December 31, 2003.  No capital gain  distributions
will be made by  Utilities  Fund until its  capital  loss  carryovers  have been
offset or have expired.

     Gains  attributable to the disposition of Global Gold's direct  investments
in gold  bullion or coins do not qualify as income for  purposes  of  satisfying
diversification tests under the Code. If a Fund realizes greater than 10% of its
income from such non-qualifying sources, it would incur federal income and state
taxes  on the  net  investment  income  and  capital  gains  it  distributes  to
shareholders.

     A Fund may be subject to a 4% excise tax on a portion of its  undistributed
income. To avoid the tax, a Fund must timely distribute annually at least 98% of
its ordinary  income (not taking into  account any capital  gains or losses) for
the  calendar  year and at least  98% of its  capital  gain net  income  for the
12-month period ending, as a general rule, on October 31st of the calendar year.
Any  distributions  declared  by a Fund in  December  and paid in January of the
following year are taxable as if they were paid on December 31st.

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

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

     Each  Fund  may  invest  in  shares  of  foreign  corporations  that may be
classified under the Code as passive foreign investment companies ("PFIC"s).  In
general,  a foreign  corporation is classified as a PFIC if at least one-half of
its assets constitute  investment-type assets or 75% or more of its gross income
is investment-type  income. Certain distributions from a PFIC and gains from the
sale  of  PFIC  shares  are  treated  as  excess  distributions.   These  excess
distributions  and gains may be subject to federal income tax.  Interest charges
may also be imposed on a Fund with respect to deferred  taxes  arising from such
excess distributions or gains.

     Each Fund's intention to qualify annually as a regulated investment company
may limit its elections with respect to PFIC shares.


Statement of Additional Information                                           17


     Because the  application of the PFIC rules may affect,  among other things,
the  character  of  gains,  the  amount of gain or loss,  and the  timing of the
recognition of income with respect to PFIC shares,  as well as subject a Fund to
tax on certain  income from PFIC shares,  the amount that must be distributed to
shareholders,  which  will be  taxed  to  shareholders  as  ordinary  income  or
long-term capital gain, may be increased or decreased  substantially compared to
that of a fund that did not invest in PFIC shares.

     Earnings  derived by a Fund from sources  outside the United  States may be
subject to non-U.S.  withholding  and possibly other taxes.  Such taxes might be
reduced or eliminated  under the terms of a U.S.  income tax treaty,  and a Fund
would  undertake any  procedural  steps required to claim the benefits of such a
treaty. With respect to any non-U.S. taxes actually paid by a Fund, if more than
50% of the value of the Fund's  total  assets at the close of any  taxable  year
consists of securities of foreign corporations, the Fund will elect to treat any
non-U.S.  income and similar  taxes it pays as though the taxes were paid by its
shareholders.

     Generally,  a credit for foreign taxes is subject to the limitation that it
may not exceed the  shareholder's  U.S. tax  attributable  to his or her taxable
income  from  foreign  sources.  Gains  realized  by a Fund  from  the  sale  of
securities will be treated as derived from U.S.  sources,  and certain  currency
gains,  including  gains  from   foreign-currency-denominated  debt  securities,
receivables,  and payables, will be treated as income derived from U.S. sources.
The limitation on the foreign tax credit is applied separately to foreign source
passive income,  which may include certain dividends  received from the Fund and
certain other types of income. Accordingly,  shareholders may be unable to claim
a credit for the full amount of their  proportionate  share of the foreign taxes
paid by a Fund.

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

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

     Generally,  a Fund will be required to  distribute  dividends  representing
discounts  on debt  securities  that  are  currently  includable  in  income  to
shareholders, even if cash representing such income has not been received by the
Fund.  Cash to pay such  dividends  may be  obtained  from  proceeds of sales of
securities held by the Fund.

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

TAXATION OF U.S. SHAREHOLDERS

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

     A gain realized on the redemption, sale, or exchange of shares would not be
affected by the reacquisition of shares. A loss realized on a redemption,  sale,
or exchange of shares would be disallowed to the

18                                                  American Century Investments


extent that the shares disposed of were replaced  (whether through  reinvestment
of  distributions  or  otherwise)  within a period of 61 days  beginning 30 days
before and ending 30 days after the date shares  were  disposed  of.  Under such
circumstances, the basis of the shares acquired would be adjusted to reflect the
disallowed loss.

TAXATION OF NON-U.S. SHAREHOLDERS

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

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

     If the  shareholder  is not  engaged in a U.S.  trade or  business,  or the
payments  received from a Fund are not  effectively  connected  with the conduct
of such a trade or business,  the shareholder  will generally be subject to U.S.
tax  withholding  at the rate of 30% (or a lower rate under an  applicable  U.S.
income tax treaty) on  distributions  of net investment  income and net realized
short-term  capital gain received.  Non-U.S.  shareholders not engaged in a U.S.
trade  or  business  or  having  no  effectively  connected  income  may also be
subject  to  U.S.  taxes  at the  rate  of  30%  (or a  lower  treaty  rate)  on
additional  distributions  as a result  of the  Fund's  election  to  treat  any
non-U.S. taxes it pays as though the taxes were paid by its shareholders.

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

     The information  above is only a summary of some of the tax  considerations
affecting the Funds and their shareholders;  no attempt has been made to discuss
individual tax consequences. Shareholders who are neither citizens nor residents
of the United States may be subject to a nonresident  alien  withholding  tax of
30% or a lower treaty rate,  depending on the country in which they reside.  The
Funds'  distributions  also may be subject to state,  local, or foreign taxes. A
prospective  investor may wish to consult a tax advisor to  determine  whether a
Fund is a suitable investment based on the investor's tax situation.

ABOUT AMERICAN CENTURY QUANTITATIVE EQUITY FUNDS

     American  Century   Quantitative   Equity  Funds  (the  "Corporation")  was
organized as a California  corporation  on December 31, 1987.  The  Corporation,
formerly known as the Benham Equity Funds,  is authorized to issue 10 series and
to issue two billion  (2,000,000,000) shares of each series. Within each series,
the Board of Directors may issue an unlimited number of shares. Currently, there
are five series in the Corporation:  American Century Global Gold Fund (formerly
known as Benham Global Gold Fund and Benham Gold Equities Index Fund),  American
Century Global Natural  Resources Fund (formerly  known as Benham Global Natural
Resources  Index Fund) and American  Century  Utilities Fund (formerly  known as
Benham  Utilities  Income Fund) are  described in this  Statement of  Additional
Information.  With  respect  to each  series,  shares  issued are fully paid and
nonassessable  and  have no  preemptive,  conversion,  or  similar  rights.  All
consideration  received by the  Corporation  for shares of any  series,  and all
assets,  income,  and gains (or losses)  earned  thereon,  belong to that series
exclusively and are subject to related liabilities.

     Shares of each series have equal voting  rights,  provided that each series
votes  separately on matters  affecting  only that series.  Each  shareholder is
entitled

Statement of Additional Information                                           19


to vote based on the total dollar interest in a Fund as of the record date for a
shareholder  meeting.  The  election of  Directors  is  determined  by the votes
received from all of the Corporation's  shareholders without regard to whether a
majority of shareholders  voted in favor of a particular nominee or all nominees
of a group.  Under California  Corporations Code Section 708,  shareholders have
the right to cumulate  votes in the  election  (or  removal) of  Directors.  For
example, if six Directors are proposed for election,  a shareholder may cast six
votes for a single candidate, three votes for each of two candidates, etc.

MANAGEMENT

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

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

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

Category Assets                                           Fee Rate
- -----------------------------------------------------------------------------
First $1 billion                                           0.5200%
Next $5 billion                                            0.4600%
Next $15 billion                                           0.4160%

</TABLE>

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

     The management  agreement shall continue in effect until the earlier of the
expiration  of two  years  from the date of its  execution  or until  the  first
meeting of  shareholders  following such execution and for as long thereafter as
its  continuance  is  specifically  approved at least annually by (1) the Funds'
Board of  Directors,  or by the vote of a  majority  of  outstanding  votes  (as
defined in the Investment  Company Act) and (2) by the vote of a majority of the
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 their shareholders for anything other than willful misfeasance, bad
faith, gross negligence or reckless disregard of its obligations and duties.

22                                                  American Century Investments


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

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

     Investment  advisory  fees paid by each Fund to the  Manager for the fiscal
years ended  December 31,  1996,  1995 and 1994 are  indicated in the  following
table. Fee amounts are net of any reimbursements  under the prior agreement with
Benham Management Corporation.

DISTRIBUTION OF FUND SHARES

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

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

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

     American Century may reject or limit the amount of an investment to prevent
any one shareholder or affiliated  group from controlling the Corporation or one
of its series; to avoid  jeopardizing a series' tax status; or whenever,  in the
Manager's  opinion,  such  rejection is in the  Corporation's  or a series' best
interest.  As of April 7, 1997, to the knowledge of the Funds,  the shareholders
