EXAMPLE:


You would pay the following expenses on a                        1 year              $10
$1,000 investment, assuming a 5% annual return and              3 years               32
redemption at the end of each time period:                      5 years               55
                                                               10 years              122
</TABLE>


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

(2)  Benham  Management  Corporation  (the  "manager")  has  agreed to limit the
     fund's  total  operating  expenses to specified  percentages  of the fund's
     average  daily net  assets.  The  agreement  provides  that the manager may
     recover  amounts  absorbed  on behalf of the fund during the  preceding  11
     months if, and to the extent that, for any given month,  fund expenses were
     less than the expense  limit in effect at that time.  The  current  expense
     limit for the fund is 1.00%.  Amounts paid by unaffiliated third parties do
     not apply to this expense  limit.  This expense  limit is subject to annual
     renewal  in June.  If the  expense  limit  was not in  effect,  the  fund's
     Management Fees, Other Expenses and Total Fund Operating  Expenses would be
     as follows, respectively: 0.66%, 0.54% and 1.20%.
    

The fund pays the manager advisory fees equal to an annualized percentage of the
fund's  average daily net assets.  Other  expenses  include  administrative  and
transfer agent fees paid to American Century Services Corporation.

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

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

discussion, see "Other Information" in the Statement of Additional Information.

INVESTMENT OBJECTIVE

The fund's  investment  objective is to seek to maximize  total return  (capital
appreciation plus dividend income)  consistent with prudent investment risk. The
fund seeks to achieve  this  objective by  allocating  its assets among (1) U.S.
equity  securities,   (2)  U.S.  fixed-income   securities,   (3)  money  market
instruments,  (4) foreign equity and fixed-income securities, and (5) securities
of companies with substantial  gold-related assets and natural resources- linked
investments.  There is no assurance  that the fund will  achieve its  investment
objective.

MANAGEMENT APPROACH

   
The fund has a neutral mix that represents the way the fund's  investments  will
be  generally  allocated  over the long term.  Working from the neutral mix, the
manager may  gradually  adjust the fund's  investments  within  their  operating
ranges to reflect either  growth-oriented  or defensive  strategies.  The fund's
neutral mix and operating range for each asset class are illustrated in the next
column.

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

Under extreme market conditions, the fund may adopt broader ranges for its asset
classes as  follows:  20-70% in stocks,  20-70% in bonds,  10-40% in  short-term
instruments,   0-40%  in  international  securities,   and  0-10%  in  specialty
securities.

This  "flexible"  investment  approach  allows  the  fund to take  advantage  of
performance  opportunities as they occur.  Fund performance may be affected by a
variety of factors, such as interest rate changes,  market conditions,  economic
events, and the manager's skill in allocating assets.

The  composition of the asset classes in the neutral mix is designed to create a
diversified  portfolio  emphasizing  total  return.  The fund's  diversification
reduces the  potential  risks from any one asset class.  No single  mutual fund,
however, can provide an appropriate balanced investment plan for all investors.

The essence of the fund's  diversification  strategy  is to produce  competitive
returns and limit volatility by owning assets that have  historically  responded
differently under similar market  conditions.  As opportunities  arise or market
conditions  warrant,  the  manager  may  alter  the  fund's  investment  mix and
particular  securities  within each asset class.  The manager  makes  investment
decisions for the fund in a two-

6    Information Regarding The Fund                 American Century Investments


tiered process by: (1)  determining  how the fund's assets should be distributed
among asset classes and (2) deciding which securities should be purchased within
each asset class.

The manager begins the decision  making  process by using a  quantitative  asset
allocation  model and a market  scenario  analysis to  determine  how the fund's
investments  should be distributed among its five asset classes,  without regard
to specific  securities.  This analysis  includes  consideration of the relative
opportunity for capital  appreciation of stocks and bonds,  dividend yields, and
the level of interest rates paid on debt securities of various maturities.

In determining the allocation of assets among U.S. and foreign capital  markets,
the manager also utilizes several analytical  techniques,  including  historical
analysis and projections for economics and markets worldwide.

In selecting  securities  denominated  in foreign  currencies,  the manager will
consider,  among other factors, the impact of foreign exchange rates relative to
the U.S. dollar value of such  securities.  The manager may use forward exchange
currency  contracts  or other  hedging  techniques  to seek to minimize  foreign
exchange rate risks. See "Currency Risk," page 10.

Periodically,  or under extraordinary  circumstances,  the manager recommends an
asset  allocation  strategy  to a committee  of senior  officers  and  portfolio
managers.  Subsequently,  the manager works with the portfolio  management  team
within their  respective  areas of  expertise to implement  changes to the asset
allocation and portfolio holdings.

INVESTMENT CATEGORIES

   
The types of  securities  the fund may buy  within  each  asset  class and their
strategic use in pursuing the fund's  objective are  illustrated in the table in
the next  column and are  described  more fully on the  following  pages.  Risks
related to each asset class and  specific  types of  investments  are  discussed
under "Risk  Factors and  Investment  Techniques,"  page 9. See the Statement of
Additional  Information for a more detailed  discussion of the fund's investment
techniques.

U.S. EQUITY SECURITIES

The fund will  generally  invest  25-45% of its total  assets in common  stocks,
preferred stocks,  convertible securities,  and warrants.  These investments may
include stocks of large, medium, and small  capitalization  companies located in
the United States.  In selecting both U.S. and foreign  equity  securities,  the
manager  considers  a variety  of factors  relating  to  dividend  and cash flow
valuation,  earnings  growth,  and the  likelihood  that  earnings  will  exceed
analysts' estimates.

Convertible  securities are bonds,  preferred stocks,  and other securities that
may be  exchanged or converted  into shares of the  issuer's  underlying  common
stock at a specific  price for a specific time period.  The value of convertible
securities  is linked to the price of the  underlying  stock and is sensitive to
interest rate changes and the credit quality of the issuer.


Prospectus                                 Information Regarding The Fund     7



The fund may buy convertible securities rated, at the time of investment, within
the top four rating categories (i.e.,  investment-grade quality) by a nationally
recognized  statistical rating  organization (a "rating agency") or, if unrated,
judged by the manager  under the  supervision  of the Board of Trustees to be of
comparable quality.

U.S. FIXED-INCOME SECURITIES

The fund will generally  invest 25-45% of its total assets in securities  issued
or guaranteed by the U.S. government and its agencies or  instrumentalities  and
in debt  obligations  issued by U.S.  corporations.  The fund may also invest in
instruments   described   under   "Mortgage-Related   and   Other   Asset-Backed
Securities," page 10.

The  fund   may  buy  debt   securities   rated,   at  the  time  of   purchase,
investment-grade  quality  by a rating  agency  or,  if  unrated,  judged by the
manager,  under the  supervision  of the Board of Trustees,  to be of comparable
quality.  The  maturities of  securities  included in this portion of the fund's
portfolio  will  generally  range  from  two to 30  years  and  may be  adjusted
depending upon the manager's perception of market and economic conditions.

SHORT-TERM INSTRUMENTS

The fund will normally invest 10-25% of its total assets in  high-quality  money
market  instruments  with  remaining  maturities  of 13  months  or  less.  Such
instruments may include obligations of U.S. or foreign  governments,  government
agencies,  and  supranational   organizations;   commercial  paper;   short-term
corporate debt obligations;  and high-quality certificates of deposit (including
non-U.S. dollar deposits).

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

   
The fund may invest up to 5% of its total assets in money  market funds  advised
by the manager,  provided  that the  investment  is  consistent  with the fund's
investment policies and restrictions.  The manager and its affiliates will waive
fees charged to the fund on amounts invested in such money market funds to avoid
duplication of expense to fund shareholders.  For temporary  defensive purposes,
the fund may invest up to 100% of its assets in short-term instruments.
    

FOREIGN EQUITY AND FIXED-INCOME SECURITIES

The  foreign  securities  segment may  consist of equity  securities  of foreign
issuers  (including common stocks,  preferred stocks,  warrants,  and securities
convertible  into common stocks) as well as debt  securities of foreign  issuers
(including  bonds,  notes and other debt securities,  and obligations of foreign
governments  and  their  political  subdivisions).  The  fund's  foreign  equity
securities  are  generally  issued by  developed  countries  in Europe,  Canada,
Mexico,  Australia,  and  the Far  East.  These  countries'  stock  markets  are
represented  in the Morgan  Stanley  Capital  International's  EAFE Index ("EAFE
Index").

The fund may buy  debt  securities  deemed  by a rating  agency,  at the time of
purchase,  to be of  investment-grade  quality  or,  if  unrated,  judged by the
manager  under the  supervision  of the Board of  Trustees  to be of  comparable
quality.

The fund does not intend to invest more than 5% of its net assets in  securities
of issuers  located in developing  countries.  The fund may also invest in other
investment  companies as described under  "Investment  Companies,"  page 11. The
fund will not invest more that 25% of its total assets in  securities of issuers
located in any one  foreign  country.  The  maturities  of foreign  fixed-income
securities included in the fund's portfolio will range from two to 30 years.

The fund  may also  invest  in  sponsored  or  unsponsored  American  Depositary
Receipts (ADRs), European Depositary Receipts (EDRs), Global Depositary Receipts
(GDRs),  International  Depositary  Receipts (IDRs), or other similar securities
convertible into securities of foreign issuers.

GOLD COMPANIES AND NATURAL RESOURCES-LINKED INVESTMENTS

The fund will  generally  invest 0-10% of its total assets in stocks of domestic
and foreign companies that are engaged in exploring for, mining, processing,


8    Information Regarding The Fund                 American Century Investments


fabricating,  or otherwise  dealing in gold and other  precious  metals (such as
silver  and  platinum)  or other  natural  resources.  Stocks  included  in this
category  must be issued by a company that derives 50% or more of its revenue or
net profits from one or more of these activities.  This segment may also include
structured notes, which are described on page 14.


RISK FACTORS AND INVESTMENT TECHNIQUES


The fund is a convenient  way to diversity  while  seeking  total  return.  Risk
exposure  to any one asset  class is  limited  by the  allocation  of the fund's
assets among various  investment  categories.  The fund may be  appropriate  for
investors seeking one-stop diversification across various investment categories,
both in the U.S.  and  abroad.  The fund  works  best  for  long-term  investors
prepared to ride out the markets' up and downs.

The  fund  cannot  assure  that  the  techniques  it uses  will  be  successful.
Diversification  among asset classes will not necessarily  protect the fund from
loss; it is possible  that several of the fund's asset  classes will  experience
losses simultaneously under certain market conditions.

EQUITY SECURITIES

Equity securities are subject to the risks of stock market investing,  including
the  possibility  of sudden or  prolonged  market  declines as well as the risks
associated with individual companies. The fund may invest in stocks of companies
of large, medium, or small  capitalization.  Investing in smaller, less seasoned
companies  may  present  greater  opportunities  for growth but also may involve
greater risks than are customarily associated with more established companies.

FIXED-INCOME SECURITIES

Fixed-income securities are affected primarily by changes in interest rates. The
prices of these securities tend to rise when interest rates fall, and conversely
fall when interest rates rise.  Interest rate changes will have a greater effect
on the  fund if it is  heavily  invested  in  long-term  or  zero-coupon  bonds.
Fixed-income securities may also be affected by changes in the credit quality of
their issuers.

Securities  rated in the lowest  investment-grade  category may have speculative
characteristics.  Changes in economic conditions or other circumstances are more
likely to lead to a weakened  capacity to make  principal and interest  payments
than is the case for higher grade bonds.  In the event that an existing  holding
is  downgraded  below  investment  grade,  the Fund will seek to  dispose of the
security, but its ability to do so may be limited by its intention to qualify as
a regulated investment company for federal tax purposes.

The fund may purchase  zero-coupon  bonds ("zeros"),  which are debt obligations
that do not  pay  interest  periodically.  Zeros  are  issued  at a  substantial
discount from their maturity value, and this discount is amortized over the life
of the security. Because interest on zeros is not distributed on a current basis
but is, in effect,  compounded,  zeros tend to be subject to greater market risk
than interest-paying securities with similar maturities.

FOREIGN SECURITIES

Foreign  securities  may  present  unique  investment  opportunities;   however,
overseas  investing  involves  risks not  associated  with  domestic  investing.
Foreign  securities markets are not always as efficient as those in the U.S. and
are often less liquid and more volatile.

Other risks involved in investing in the securities of foreign  issuers  include
differences in accounting, auditing and financial reporting standards; generally
higher   commission   rates  on  foreign   portfolio   transactions;   political
instability,  which could  affect U.S.  investments  in foreign  countries;  and
potential restrictions on the flow of capital.

The extent of the support of foreign government obligations varies. Some foreign
government  obligations are direct  obligations of the foreign  government.  The
payment of principal and interest is unconditionally guaranteed on certain other
foreign government securities.  Other foreign government obligations are neither
direct  obligations  of, nor  guaranteed  by, a foreign  government  but involve
government sponsorship in one way or another, such as specific collateralization
or support by the credit of the issuing  government  agency or  instrumentality.
Foreign taxes can also affect the fund's performance.  For further details,  see
"Taxes," page 23 and the Statement of Additional Information.

Prospectus                                 Information Regarding The Fund     9


CURRENCY RISK

Currency risk will affect the value of  foreign-currency-denominated  securities
when foreign  exchange rates  fluctuate.  Currency risks are generally higher in
lesser  developed  markets.  The fund may,  however,  engage in foreign currency
transactions to protect its portfolio against  fluctuations in currency exchange
rates in relation to the U.S.  dollar.  Such foreign  currency  transactions may
include forward foreign currency contracts,  currency exchange transactions on a
spot (i.e., cash) basis, put and call options on foreign currencies, and foreign
exchange futures contracts.

GOLD COMPANIES AND NATURAL RESOURCES-LINKED INVESTMENTS

When the economy is threatened by inflation,  the fund may increase its holdings
in gold stocks to benefit from rising  commodities prices and offset bond market
declines.  Based upon  historical  experience,  during  periods of  economic  or
financial  instability,  the prices of securities of companies  included in this
segment  reflect  the  price  volatility  of gold and other  natural  resources.
Instability  of prices may affect  earnings of such  companies and may adversely
affect the financial  condition of such companies.  In addition,  some companies
involved  in  natural  resources  businesses  may also be  subject  to the risks
generally  associated with extraction of natural  resources,  such as oil spills
and as well as be vulnerable to natural disasters including,  but not limited to
fire, flood, and drought.


OTHER INVESTMENT PRACTICES, THEIR CHARACTERISTICS AND RISKS


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

PORTFOLIO TURNOVER

The portfolio  turnover  rate of the fund is shown in the  Financial  Highlights
table on page 5 of this Prospectus.

Investment   decisions  to  purchase  and  sell  securities  are  based  on  the
anticipated  contribution of the security in question to the fund's  objectives.
The manager  believes that the rate of portfolio  turnover is irrelevant when it
determines a change is in order to achieve those  objectives  and,  accordingly,
the annual portfolio turnover rate cannot be anticipated.

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

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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

MORTGAGE-RELATED AND OTHER ASSET-BACKED SECURITIES

The fund may purchase mortgage  pass-through  securities,  subject to the fund's
limits on investments in U.S.  fixed-income  securities.  Mortgage  pass-through
securities represent interests in "pools" of mortgages in which payments of both
interest and  principal on the  securities  are generally  made  monthly.  These
monthly mortgage  payments are in effect "passed through" to the security holder
(minus fees paid to the security's issuer or guarantor). These securities may be
subject to prepayment risk.

The primary  issuers of mortgage  securities are the Federal  National  Mortgage
Association  ("FNMA"),  the Federal Home Loan Mortgage Corporation ("FHLMC") and
the Government National Mortgage Association ("GNMA"). Payments of principal and
interest on GNMA  securities are guaranteed by GNMA and backed by the full faith
and credit of the U.S. government. Because FNMA and FHLMC have

10   Information Regarding The Fund                American Century Investments


close  relationship with the U.S.  government,  even though their securities are
not backed by the full faith and credit of the U.S.  government,  they are high-
quality securities with minimal credit risks.

The fund may also invest in collateralized mortgage obligations. See "Derivative
Securities" on page 12 for more details.

BORROWING

The fund may borrow money only for temporary or emergency  purposes.  Borrowings
are not expected to exceed 5% of the fund's total assets.

PORTFOLIO LENDING

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

RULE 144A SECURITIES

The fund may, from time to time, purchase Rule 144A securities when they present
attractive  investment  opportunities that otherwise meet the fund's established
criteria for selection.  Rule 144A  securities are securities that are privately
placed with and traded among qualified  institutional  investors rather than the
general  public.  Although  Rule  144A  securities  are  considered  "restricted
securities," they are not necessarily illiquid.

With respect to securities eligible for resale under Rule 144A, the staff of the
SEC has  taken  the  position  that  the  liquidity  of such  securities  in the
portfolio of a fund offering redeemable securities is a question of fact for the
Board  of  Trustees  to  determine,  such  determination  to  be  based  upon  a
consideration  of the readily  available  trading  markets and the review of any
contractual restrictions.  Accordingly, the Board of Trustees is responsible for
developing and  establishing  the guidelines and procedures for  determining the
liquidity  of Rule  144A  securities.  As  allowed  by Rule  144A,  the Board of
Trustees of the fund has delegated the day-to-day  function of  determining  the
liquidity  of Rule  144A  securities  to the  manager.  The  Board  retains  the
responsibility to monitor the implementation of the guidelines and procedures it
has adopted.

Since the secondary  market for such securities is limited to certain  qualified
institutional  investors,  the  liquidity  of  such  securities  may be  limited
accordingly and a fund may, from time to time, hold a Rule 144A security that is
illiquid.  In such an event, the manager will consider  appropriate  remedies to
minimize the effect on such fund's liquidity.  The fund may not invest more than
15% 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 COMPANIES

   
The fund has received an  exemptive  order from the SEC to permit it to invest a
portion of its assets in the American  Century--Benham  European Government Bond
Fund (the "EuroBond Fund"), a series of the American Century  International Bond
Funds,  and any  future  international  funds  established  and  advised  by the
manager.
    

The manager believes that by investing in foreign  securities through investment
in funds such as the  EuroBond  Fund,  the fund may achieve  economies  of scale
resulting  in lower fees paid to managers  skilled in  international  investing;
lower  custodial,   brokerage  and  other  transactional   costs,  and  enhanced
diversification of the fund's assets.

The EuroBond Fund's investment objective is to seek over the long term as high a
level of total return as is consistent  with  investment in the  highest-quality
European government debt securities.  To avoid paying duplicative fees, the fund
will not pay the manager advisory fees for any portion of its assets invested in
any fund advised by the manager or its affiliates.

Prospectus                                 Information Regarding The Fund     11


DERIVATIVE SECURITIES

The fund may invest in securities that are commonly  referred to as "derivative"
securities.  Generally,  a derivative  is a financial  arrangement  the value of
which is based on, or "derived" from, a traditional  security,  asset, or market
index.   Certain  derivative   securities  are  more  accurately   described  as
"index/structured"   securities.   Index/structured  securities  are  derivative
securities whose value or performance is linked to other equity securities (such
as depositary receipts),  currencies, interest rates, indices or other financial
indicators ("reference indices").

Some derivatives such as mortgage-related and other asset-backed  securities are
in many respects like any other  investment,  although they may be more volatile
or less liquid than more traditional debt securities.

There are many  different  types of  derivatives  and many different ways to use
them. Futures and options are commonly used for traditional  hedging purposes to
attempt to protect a fund from exposure to changing  interest rates,  securities
prices,  or  currency  exchange  rates  and for cash  management  purposes  as a
low-cost method of gaining  exposure to a particular  securities  market without
investing directly in those securities.

The fund may not invest in a derivative  security  unless the reference index or
the  instrument to which it relates is an eligible  investment for the fund. For
example,  a security whose  underlying value is linked to the price of oil would
not be a  permissible  investment  since the fund may not  invest in oil and gas
leases or futures.

The return on a derivative  security may  increase or decrease,  depending  upon
changes in the reference index or instrument to which it relates.

There are a range of risks associated with derivative investments, including:

o    the risk that the underlying security, interest rate, market index or other
     financial  asset  will  not move in the  direction  the  portfolio  manager
     anticipates;

o    the  possibility  that  there may be no  liquid  secondary  market,  or the
     possibility that price  fluctuation  limits may be imposed by the exchange,
     either of which may make it difficult or impossible to close out a position
     when desired;

o    the risk that adverse price movements in an instrument can result in a loss
     substantially greater than a fund's initial investment; and

o    the risk that the counterparty will fail to perform its obligations.

The fund may use derivatives to enhance return and for hedging,  not leveraging,
purposes.  A description  of the  derivatives  that the fund may use and some of
their associated risks follows.

The Board of Trustees has approved the manager's policy regarding investments in
derivative securities.  That policy specifies factors that must be considered in
connection with a purchase of derivative securities. The policy also establishes
a committee that must review certain proposed purchases before the purchases can
be made.  The manager will report on fund activity in  derivative  securities to
the Board of  Trustees  as  necessary.  In  addition,  the Board will review the
manager's policy for investments in derivative securities annually.

INTEREST RATE FUTURES CONTRACTS AND OPTIONS THEREON

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

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

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

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

Since futures contracts and options thereon can replicate  movements in the cash
markets for the securities in which a fund invests without the large cash

12   Information Regarding The Fund                 American Century Investments


investments  required  for dealing in such  markets,  they may subject a fund to
greater and more volatile risks than might  otherwise be the case. The principal
risks related to the use of such instruments are (1) the offsetting  correlation
between  movements in the market  price of the  portfolio  investments  (held or
intended) being hedged and in the price of the futures contract or option may be
imperfect;  (2)  possible  lack of a liquid  secondary  market for  closing  out
futures or option  positions;  (3) the need of additional  portfolio  management
skills  and  techniques;  and  (4)  losses  due to  unanticipated  market  price
movements.  For a hedge to be  completely  effective,  the  price  change of the
hedging instrument should equal the price change of the securities being hedged.
Such  equal  price  changes  are not  always  possible  because  the  investment
underlying the hedging  instrument may not be the same  investment that is being
hedged.

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

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

FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS

Some of the foreign  securities  held by the fund may be  denominated in foreign
currencies.  Other securities, such as ADRs, may be denominated in U.S. dollars,
but have a value that is dependent on the performance of a foreign security,  as
valued in the currency of its home country. As a result, the value of the fund's
portfolio  may be  affected by changes in the  exchange  rates  between  foreign
currencies  and the  dollar,  as well as by changes in the market  values of the
securities  themselves.  The performance of foreign  currencies  relative to the
dollar may be a factor in the overall performance of the fund.

To protect against adverse movements in exchange rates between  currencies,  the
fund may,  for  hedging  purposes  only,  enter into  forward  foreign  currency
exchange  contracts.  A forward foreign currency exchange  contract  obligates a
fund to  purchase  or sell a specific  currency  at a future  date at a specific
price.

The fund may elect to enter into a forward foreign  currency  exchange  contract
with  respect to a specific  purchase or sale of a security,  or with respect to
the fund's portfolio positions generally.

By entering into a forward foreign  currency  exchange  contract with respect to
the specific  purchase or sale of a security  denominated in a foreign currency,
the fund can "lock in" an exchange rate between the trade and  settlement  dates
for  that  purchase  or  sale.  This  practice  is  sometimes   referred  to  as
"transaction  hedging." The fund may enter into  transaction  hedging  contracts
with respect to all or a substantial portion of its foreign securities trades.

When the  manager  believes  that a  particular  currency  may  decline in value
compared to the dollar, a fund may enter into forward foreign currency  exchange
contracts  to sell the value of some or all of the fund's  portfolio  securities
either  denominated in, or whose value is tied to, that currency.  This practice
is sometimes  referred to as "portfolio  hedging." The fund may not enter into a
portfolio  hedging  transaction where it would be obligated to deliver an amount
of foreign currency in excess of the aggregate value of its portfolio securities
or other assets denominated in, or whose value is tied to, that currency.

The fund will make use of the portfolio hedging to the extent deemed appropriate
by the  manager.  However,  it is  anticipated  that the fund  will  enter  into
portfolio hedges much less frequently than transaction hedges.

   
If the fund  enters  into a forward  contract,  the fund,  when  required,  will
instruct its custodian bank to segregate cash or appropriate  liquid assets in a
separate  account  in an amount  sufficient  to cover its  obligation  under the
contract.  Those assets will be valued at market daily,  and if the value of the
segregated  securities declines,  additional cash or securities will be added so
that the  value  of the  account  is not less  than  the  amount  of the  fund's
commitment.
    

Predicting the relative future values of currencies is very difficult, and there
is no  assurance  that any attempt to protect a fund  against  adverse  currency
movements through the use of forward foreign cur-

Prospectus                                 Information Regarding The Fund     13


rency exchange  contracts will be  successful.  In addition,  the use of forward
foreign  currency  exchange  contracts  tends to limit the potential  gains that
might  result from a positive  change in the  relationships  between the foreign
currency and the U.S. dollar.

WARRANTS

Warrants are instruments  issued by a corporation that give the holder the right
to subscribe to a specific  amount of the  corporation's  capital stock at a set
price for a specified  period of time.  The fund may invest up to 10% of its net
assets in  warrants,  except  that this  limitation  does not apply to  warrants
acquired in units or attached to securities.

COLLATERALIZED MORTGAGE OBLIGATIONS

Collateralized  mortgage  obligations are  mortgage-backed  securities issued by
government agencies; single-purpose,  stand-alone financial subsidiaries; trusts
established by financial institutions; or similar institutions.  CMOs are hybrid
instruments  with  characteristics  of both  mortgage-backed  bonds and mortgage
pass-through securities.  Similar to a bond, interest and principal on a CMO are
paid monthly,  quarterly,  or semiannually.  CMOs may be collateralized by whole
mortgage loans but are more typically  collateralized  by portfolios of mortgage
pass-through securities guaranteed by GNMA, FHLMC, or FNMA.

CMOs are categorized in multiple classes, or "tranches," with each class bearing
a  different   stated  maturity.   Monthly  payments  of  principal,   including
prepayments,  are returned to investors in ascending order of the maturity class
they hold.

Floating-rate CMO tranches  ("floaters") pay a variable rate of interest that is
usually tied to the London Interbank Offered Rate. "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.  The yield of any floater is sensitive to the rate of prepayments as well
as to the level of the applicable  index.  Low levels of the index will reduce a
floater's  yield,  while an  interest  rate cap on the  floater  will  limit the
floater's  yield  when the  level of the  index  is  high.  Because  the rate of
interest paid on an inverse  floater often varies  inversely  with a multiple of
the index,  any change in the index may have an exaggerated  effect on the yield
of the inverse floater.

STRUCTURED NOTES

The fund may  invest up to 5% of its  total  assets in  structured  notes  whose
coupons  or  principal  value  is  linked  to the  performance  of a  particular
commodity  or index  price.  Structured  notes may have  return  characteristics
similar to direct  investments  in the  underlying  instrument or to one or more
options on the underlying instrument. Structured notes may be more volatile than
the underlying instrument itself and present many of the same risks as investing
in futures  and  options.  Structured  notes are also  subject  to credit  risks
associated with the issuer of the security.  The fund's investment in structured
notes is subject to the limits of the fund's  investment  in gold  companies and
natural resources-linked investments as well as to considerations related to the
Fund's tax status.

CASH MANAGEMENT

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

OTHER TECHNIQUES

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


PERFORMANCE ADVERTISING


From time to time, the fund may advertise performance data. Fund performance may
be  shown  by  presenting  one  or  more  performance  measurements,   including
cumulative  total return or average  annual total  return,  yield and  effective
yield.

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

14   Information Regarding The Fund                 American Century Investments


the same period if the fund's performance had remained constant throughout.

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

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

   
Yields are calculated  according to accounting  methods that are standardized in
accordance  with SEC rules.  The SEC yield  should be regarded as an estimate of
the fund's rate of  investment  income,  and it may not equal the fund's  actual
income  distribution  rate, the income paid to a shareholder's  account,  or the
income reported in the fund's financial statements.
    

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

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

As long as you meet any minimum investment  requirements,  you may exchange your
Fund shares to our other funds up to six times per year per account. An exchange
request will be processed  the same day it is received if it is received  before
the funds' net asset values are calculated, which is one hour prior to the close
of the New York Stock Exchange for American Century Target Maturities Trust, and
at the close of the Exchange  for all of our other funds.  See "When Share Price
is Determined," page 22.

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

HOW TO REDEEM SHARES


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

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

BY MAIL

Your written  instructions  to redeem  shares may be made either by a redemption
form,  which we will send to you upon  request,  or by a letter  to us.  Certain
redemptions may require a signature guarantee. Please see "Signature Guarantee,"
page 19.

BY TELEPHONE

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

BY CHECK-A-MONTH

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

OTHER AUTOMATIC REDEMPTIONS

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

REDEMPTION PROCEEDS

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

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

BY CHECK

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

BY WIRE AND ACH

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

Your bank will  usually  receive  wired funds  within 48 hours of  transmission.
Funds  transferred  by ACH may be received up to seven days after  transmission.
Wired  funds  are  subject  to a $10 fee to cover  bank wire  charges,  which is
deducted from redemption proceeds.  Once the funds are transmitted,  the time of
receipt and the funds' availability are not under our control.

REDEMPTION OF SHARES IN LOW-BALANCE ACCOUNTS

Whenever  the shares held in an account  have a value of less than the  required
minimum, a letter will

18 How To Invest With American Century Investments  American Century Investments


be sent advising you to either bring the value of the shares held in the account
up to the minimum or to establish an automatic investment that is the equivalent
of at least $50 per month. If action is not taken within 90 days of the letter's
date,  the shares held in the account  will be redeemed  and  proceeds  from the
redemption will be sent by check to your address of record. We reserve the right
to increase the investment minimums.


SIGNATURE GUARANTEE


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

     o    redeeming more than $25,000; or

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

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

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

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


SPECIAL SHAREHOLDER SERVICES


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

Our special shareholder services include:

AUTOMATED INFORMATION LINE

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

ONLINE ACCOUNT ACCESS

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

OPEN ORDER SERVICE

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

If the fund you have selected deducts a distribution  from its share price, your
order  price  will  be  adjusted   accordingly  so  the  distribution  does  not
inadvertently  trigger an open order transaction on your behalf. If you close or
re-register  the  account  from which the shares are to be  redeemed,  your open
order will be canceled.

Because of their  time-sensitive  nature,  open order  transactions are accepted
only by  telephone  or in person.  These  transactions  are  subject to exchange
limita-

tions described in each fund's prospectus,  except that orders and cancellations
received  before 2 p.m.  Central time are  effective the same day, and orders or
cancellations received after 2 p.m. Central time are effective the next business
day.

TAX-QUALIFIED RETIREMENT PLANS

Each fund is available for your  tax-deferred  retirement plan. Call or write us

IMPORTANT POLICIES REGARDING YOUR  INVESTMENTS


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

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

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

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

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

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

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

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

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

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

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

EMPLOYER-SPONSORED RETIREMENT PLANS AND INSTITUTIONAL ACCOUNTS


Information  contained in our Investor  Services Guide pertains to  shareholders
who  invest   directly   with   American   Century   rather   than   through  an
employer-sponsored retirement plan or through a financial intermediary.

If  you   own  or  are   considering   purchasing   fund   shares   through   an
employer-sponsored retirement plan, your ability to purchase shares of the fund,
exchange them for shares of other American  Century funds,  and redeem them will
depend on the terms of your plan.

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

You may  reach  one of our  Institutional  Service  Representatives  by  calling
1-800-345-3533 to request information about our funds and services,  to obtain a

                     ADDITIONAL INFORMATION YOU SHOULD KNOW


SHARE PRICE


WHEN SHARE PRICE IS DETERMINED

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

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

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

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

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

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

HOW SHARE PRICE IS DETERMINED

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

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

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

WHERE TO FIND INFORMATION ABOUT SHARE PRICE

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

22 Additional Information You Should Know          American Century Investments



DISTRIBUTIONS


Distributions  from net  investment  income  are  declared  and paid  quarterly.
Distributions from net realized securities gains, if any, generally are declared
and paid once a year,  but the fund may make  distributions  on a more  frequent
basis to comply with the distribution requirements of the Internal Revenue Code,
in all events in a manner consistent with the provisions of the 1940 Act.

You will begin to participate in the  distributions  the day after your purchase
is  effective.  See "When  Share  Price is  Determined,"  page 22. If you redeem
shares,  you  will  receive  the  distribution  declared  for  the  day  of  the
redemption.  If all shares are redeemed, the distribution on the redeemed shares
will be included with your redemption proceeds.

Participants in employer-sponsored retirement or savings plans must reinvest all
distributions.    For   shareholders   investing   through   taxable   accounts,
distributions  will be  reinvested  unless  you elect to  receive  them in cash.
Distributions of less than $10 generally will be reinvested.  Distributions made
shortly  after a  purchase  by check  or ACH may be held up to 15 days.  You may
elect to have distributions on shares held in Individual Retirement Accounts and
403(b)  plans  paid  in  cash  only  if you  are at  least  591/2  years  old or
permanently and totally disabled. Distribution checks normally are mailed within
seven days after the record date. Please consult our Investor Services Guide for
further information regarding your distribution options.

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

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


TAXES


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

TAX-DEFERRED ACCOUNTS

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

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

TAXABLE ACCOUNTS

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

Distributions are taxable to you regardless of whether they are taken in cash or
reinvested, even if the value of your shares is below your cost. If you purchase
shares shortly before a capital gain distribution,  you must pay income taxes on
the distribution,  even though the value of your investment (plus cash received,
if any) will not have  increased.  In addition,  the share price at the time you
purchase shares may include unrealized gains in the securities held in the

Prospectus                        Addtitional Information You Should Know     23


investment portfolio of the fund. If these portfolio securities are subsequently
sold and the gains are realized,  they will, to the extent not offset by capital
losses, be paid to you as a distribution of capital gains and will be taxable to
you as short-term or long-term capital gains.

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

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

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

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


MANAGEMENT


INVESTMENT MANAGEMENT

   
The fund is a diversified, open-end series of the American Century Manager Funds
(the  "Trust"),  organized as a  Massachusetts  business trust on July 12, 1994,
formerly known as Benham Manager Funds.  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  advisory  agreement
entered into with the Trust, the manager serves as the investment advisor to the
fund. Its principal  place of business is 1665 Charleston  Road,  Mountain View,
California 94043. The manager has been providing investment advisory services to
investment companies and other clients since 1971.
    

In  June  1995,  American  Century  Companies,   Inc.  ("ACC")  acquired  Benham
Management  International,  Inc., the then-parent company of the manager. In the
acquisition, the manager became a wholly owned subsidiary of ACC.

The manager  supervises  and manages the  investment  portfolio  of the fund and
directs the purchase and sale of its investment securities. It utilizes teams of
portfolio managers, assistant portfolio managers and analysts acting together to
manage the  assets of the fund.  The team meets  regularly  to review  portfolio
holdings and to discuss purchase and sale activity. The team adjusts holdings in
the fund's portfolio as it deems appropriate in pursuit of the fund's investment
objective.  Individual  portfolio  manager  members of the team may also  adjust
portfolio  holdings of a fund or of sectors of a fund as necessary  between team
meetings.

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

JEFFREY TYLER,  Senior Vice  President,  has been primarily  responsible for the
day-to-day  management  of the fund since  December  1994.  Mr.  Tyler heads the
manager's fixed income portfolio  department and joined the manager in 1987. Mr.
Tyler has a bachelor's

24 Addtitional Information You Should Know          American Century Investments


degree in Business  Economics from the University of California at Santa Barbara
and a Master of  Management  degree in Finance and Economics  from  Northwestern
University.

DONG ZHANG,  Portfolio Manager,  has been responsible for the equity investments
of the fund since June 1996.  Mr.  Zhang joined the manager in 1993 and received
his Ph.D. in Physics from Stanford University.

BRIAN HOWELL,  Portfolio Manager,  has been a member of the portfolio management
team that  manages the fund since June 1996.  Mr.  Howell  joined the manager in
1987 as a research  analyst and was promoted to his current  position in January
1994.

The  activities of the manager are subject only to direction of the fund's Board
of Trustees.  For the  services  provided to the fund,  the manager  receives an
annual fee which cannot exceed 0.65% of average daily net assets.  The manager's
fee drops to a marginal  rate of 0.27% of average daily net assets as the fund's
assets increase.

CODE OF ETHICS

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

TRANSFER AND ADMINISTRATIVE SERVICES

American Century Services Corporation,  4500 Main Street, Kansas City, Missouri,
64111, (the "transfer agent") 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 fund. For administrative  services,  the fund pays
the  transfer  agent 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.  The  administrative fee rate ranges from 0.11% to 0.08%
of average daily net assets, dropping as assets advised by the manager increase.
For transfer agent services,  the fund pays the transfer agent a monthly fee for
each  shareholder  account  maintained  and  for  each  shareholder  transaction
executed during that month.

   
The fund  charges  no sales  commissions,  or  "loads,"  of any  kind.  However,
investors  who do not choose to purchase or sell fund shares  directly  from the
transfer   agent  may   purchase   or  sell  fund  shares   through   registered
broker-dealers and other qualified service  providers,  who may charge investors
fees for their services.  These  broker-dealers and service providers  generally
provide  shareholder,  administrative  and/or  accounting  services  which would
otherwise be provided by the transfer agent. To accommodate these investors, the
manager and its affiliates have entered into agreements with some broker-dealers
and service  providers to provide  these  services.  Fees for such  services are
borne  normally by the fund at the rates  normally  paid to the transfer  agent,
which would otherwise provide the services. Any distribution expenses associated
with these arrangements are borne by the manager.
    

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

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


DISTRIBUTION OF FUND SHARES


The fund's shares are distributed by American Century Investment Services,  Inc.
(the "Distributor"), a registered broker-dealer and an affiliate of the manager.
The manager pays all expenses for  promoting  and  distributing  the fund shares
offered by this Prospectus.  The fund does not pay any commissions or other fees
to the Distributor or to any other broker-

Prospectus                        Addtitional Information You Should Know     25


dealers or financial  intermediaries in connection with the distribution of fund
shares.


EXPENSES


The fund pays certain operating  expenses directly,  including,  but not limited
to: custodian, audit, and legal fees; fees of the independent Trustees; costs of
printing and mailing prospectuses,  statements of additional information,  proxy
statements, notices, and reports to shareholders;  insurance expenses; and costs
of  registering  the fund's shares for sale under  federal and state  securities
laws. See the Statement of Additional Information for a more detailed discussion
of independent Trustee compensation.


FURTHER INFORMATION ABOUT AMERICAN CENTURY


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

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

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

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

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

Unless  required by the 1940 Act, it will not be necessary for the Trust to hold
annual meetings of  shareholders.  As a result,  shareholders  may not vote each
year on the  election of  Trustees  or the  appointment  of  auditors.  However,
pursuant to the Trust's by-laws, the holders of shares representing at least 10%
of the votes  entitled  to be cast may  request  that the  Trust  hold a special
meeting of shareholders.  The Trust will assist in the communication  with other
shareholders.

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

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

INVESTMENT POLICIES 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.

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.

The advisor attempts to minimize the risks associated with repurchase agreements
by adhering to the following criteria:

     (1)  Limiting the securities acquired and held by the Fund under repurchase
          agreements to U.S. government securities;

     (2)  Entering into repurchase  agreements only with primary dealers in U.S.
          government securities (including bank affiliates) who are deemed to be
          creditworthy under guidelines  established by a nationally  recognized
          statistical  rating  organization (a "rating  agency") and approved by
          the Fund's Board of Trustees;

     (3)  Monitoring  the  creditworthiness  of all firms involved in repurchase
          agreement transactions;

     (4)  Requiring  the seller to establish  and maintain  collateral  equal to
          102% of the  agreed-upon  resale price,  provided,  however,  that the
          Board of Trustees may determine that a broker-dealer's credit standing
          is  sufficient  to allow  collateral  to fall to as low as 101% of the
          agreed-upon resale price before the broker-dealer  deposits additional
          securities with the Fund's custodian or subcustodian;

     (5)  Investing  no more than 15% of the  Fund's  net  assets in  repurchase
          agreements  that  mature in more than  seven days  (together  with any
          other illiquid security the Fund holds); and

     (6)  Taking delivery of all securities subject to repurchase  agreement and
          holding them in an account at the Fund's custodian bank.

The Fund has received  permission  from the Securities  and Exchange  Commission
("SEC") to participate in pooled  repurchase  agreements  collateralized by U.S.
government  securities with other mutual funds advised by the Fund's  investment
advisor,  Benham  Management  Corporation  (the  "Manager").  Pooled  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).

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 settle-

2                                                   American Century Investments


ment 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  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

Statement of Additional Information                                           3


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  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

4                                                   American Century Investments


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.

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

Statement of Additional Information                                           5


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 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.

6                                                   American Century Investments


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 the
following guidelines prescribed by the Board of Trustees:

(1)  TYPE AND AMOUNT OF  COLLATERAL.  At the time a loan is made,  the Fund must
     receive,  from or on behalf of the borrower,  collateral  consisting of any
     combination  of cash and full faith and credit U.S.  government  securities
     equal to not less than 102% of the market value of the  securities  loaned.
     Cash collateral  received by the Fund in connection with loans of portfolio
     securities  may be commingled by the Fund's  custodian  with other cash and
     marketable  securities,  provided that the loan agreement  expressly allows
     such commingling.  The loan must not reduce the risk of loss or opportunity
     for gain in the securities loaned.

(2)  ADDITIONS TO COLLATERAL. Collateral must be marked to market daily, and the
     borrower must agree to add  collateral to the extent  necessary to maintain
     the 102% level  specified  in  guideline  (1).  The  borrower  must deposit
     additional collateral no later than the business day following the business
     day on which a collateral  deficiency  occurs or  collateral  appears to be
     inadequate.

(3)  TERMINATION OF LOAN. The Fund must have the option to terminate any loan of
     portfolio  securities  at any  time.  The  borrower  must be  obligated  to
     redeliver the borrowed securities within

Statement of Additional Information                                           7


     the normal settlement period following receipt of the termination notice.

(4)  REASONABLE  RETURN ON LOAN.  The borrower must agree that the Fund (a) will
     receive  all  dividends,   interest,   or  other  distributions  on  loaned
     securities and (b) will be paid a reasonable return on such loans either in
     the form of a loan fee or premium or from the retention by the Fund of part
     or all of the earnings and profits  realized  from the  investment  of cash
     collateral in full faith and credit U.S government securities.

(5)  LIMITATIONS ON PERCENTAGE OF PORTFOLIO SECURITIES ON LOAN. The Fund's loans
     may not exceed 331/3% of its total assets.

(6)  CREDIT ANALYSIS.  As part of the regular monitoring procedures set forth by
     the Board of  Trustees  that the  Manager  follows  to  evaluate  banks and
     broker-dealers in connection with, for example,  repurchase  agreements and
     municipal  securities  credit issues,  the Manager will analyze and monitor
     the   creditworthiness   of  all  borrowers  with  whom  portfolio  lending
     arrangements are proposed or made.

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)  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

8                                                   American Century Investments


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
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).

Statement of Additional Information                                           9


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 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.

10                                                  American Century Investments


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  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.
    

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

12                                                  American Century Investments


     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.

(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),
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
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:

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

14                                                  American Century Investments


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 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 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 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 share-

16                                                  American Century Investments


holders 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 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 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
the Fund.

INVESTMENT ADVISORY SERVICES


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
