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 Directors.

U.S. GOVERNMENT SECURITIES

     The Funds may invest in U.S. government securities,  including bills, notes
and bonds issued by the U.S.  Treasury and  securities  issued or  guaranteed by
agencies  or  instrumentalities  of the U.S.  government.  Some U.S.  government
securities  are supported by the direct full faith and credit pledge of the U.S.
government;  others are  supported by the right of the issuer to borrow from the
U.S.  Treasury;  others,  such as  securities  issued  by the  Federal  National
Mortgage Association,  are supported by the discretionary  authority of the U.S.
government to purchase the agencies' obligations; and ot hers are supported only
by the  credit  of the  issuing  or  guaranteeing  instrumentality.  There is no
assurance  that  the  U.S.  government  will  provide  financial  support  to an
instrumentality it sponsors when it is not obligated by law to do so.

REPURCHASE AGREEMENTS

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

    Benham Management Corporation (the "Manager") attempts to minimize the risks
associated with repurchase agreements by adhering to the following criteria:

(1)  Limiting  the  securities  acquired  and  held by a Fund  under  repurchase
     agreement 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
     Funds' Board of Directors;

(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
     Directors  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 pr ice before the broker-dealer  deposits additional securities with
     the Funds' custodian;

(5)  Investing no more than 5% of a Fund's total 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 Funds' custodian bank.

     The  Funds  have  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 its investment
advisor,  Benham Management  Corporation.  Pooled repos are expected to increase
the  income the Funds can earn from repo  transactions  without  increasing  the
risks associated with these transactions.

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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


     When purchasing  securities on a when-issued or forward commitment basis, a
Fund assumes the rights and risks of ownership, including the risks of price and
yield  fluctuations.  While a Fund will make  commitments  to  purchase  or sell
securities on a when-issued  or forward  commitment  basis with the intention of
actually  receiving or delivering them, it may 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, a
Fund will establish and maintain until the settlement date a segregated  account
consisting of cash, cash  equivalents,  or high-quality  securities in an amount
sufficient  to  meet  the  purchase  price.  When  the  time  comes  t o 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
capital gains or losses.

     As an  operating  policy,  each 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 a Fund's total assets to be
committed under when-issued or forward commitment agreements,  t he Manager need
not sell such commitments,  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 at least 35%. In addition, as an operating policy,
each Fund will not enter into  when-issued  or forward  commitment  transactions
with settlement dates exceeding 120 days.

CONVERTIBLE SECURITIES

    Each Fund may buy securities that are convertible into common stock.  Listed
below is a brief description of the various types of convertible  securities the
Funds may buy.

     CONVERTIBLE BONDS are issued with lower coupons than  nonconvertible  bonds
of the same quality and  maturity,  but they give holders the option to exchange
their bonds for a specific  number of shares of the company's  common stock at a
predetermined  price.  This  structure  allows the  convertible  bond  holder to
participate in share price movements in the company's  common stock.  The actual
return on a convertible bond may exceed its stated yield if the company's common
stock  appreciates  in value and the option to convert to common shares  becomes
more valuable.


     CONVERTIBLE  PREFERRED  STOCKS are nonvoting  equity  securities that pay a
fixed  dividend.   These  securities  have  a  convertible  feature  similar  to
convertible  bonds;  however,  they do not have a  maturity  date.  Due to their
fixed-income  features,  convertible  issues typically are more sensitive to int
erest  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

    Although the Funds may buy securities of foreign issuers in foreign markets,
most of their foreign  securities  investments  are made by purchasing  American
Depositary Receipts (ADRs),  "ordinary shares," or "New York Shares" in the U.S.
The Funds may invest in  foreign-currency-denominated  securiti es that trade in
foreign  markets  if  the  Manager   believes  that  such  investments  will  be
advantageous to the Funds.

     ADRs  are   dollar-denominated   receipts  representing  interests  in  the
securities  of a foreign  issuer.  They are  issued by U.S.  banks and traded on
exchanges or over the counter in the U.S.  Ordinary shares are shares of foreign
issuers  that are traded  abroad  and on a U.S.  exchange.  New York  shares are
shares  that a foreign  issuer  has  allocated  for  trading  in the U.S. A DRs,
ordinary shares, and New York shares all may be purchased with and sold for U.S.
dollars,  which protects the Fund from the foreign  settlement  risks  described
below.

    Investing in foreign  companies may involve  risks not typically  associated
with investing in U.S. companies. The value of securities denominated in foreign
currencies and of dividends from such securities can change  significantly  when
foreign  currencies  strengthen or weaken relative to the U.S.  dollar.  Foreign
securities  markets  generally  have less trading volume and less liquidity than
U.S. markets, and prices in some foreign markets can be very volatile.

     Many foreign  countries lack uniform  accounting  and disclosure  standards
comparable to those that

     Statement of Additional Information                               3

apply  to  U.S.  companies,  and it may be more  difficult  to  obtain  reliable
information regarding a foreign issuer's financial condition and operations.  In
addition, the costs of foreign investing, including withholding taxes, brokerage
commissions,   and  custodial  fees,  are  generally   higher  than  for  U.  S.
investments.

     Foreign markets may offer less  protection to investors than U.S.  markets.
Foreign  issuers,  brokers,  and  securities  markets  may be  subject  to  less
governmental  supervision.  Foreign security trading practices,  including those
involving  the release of assets in advance of payment,  may involve  incr eased
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 as sets,
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 countr ies 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,  a 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 us
ually 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 a future date
and price.  By  entering  into a forward  contract  to buy or sell the amount of
foreign currency involved in a security  transaction for a fixed amou nt of U.S.
dollars,  the Manager can protect a 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 s hould be noted that
using forward  contracts to protect a Fund's foreign  investments  from currency
fluctuations  does not eliminate  fluctuations  in the prices of the  underlying
securities  themselves.  Forward  contracts  simply establish a rate of exchange
that can be  achieved  at some  future  point in ti me.  Additionally,  although
forward  contracts  tend to  minimize  the risk of loss due to a decline  in the
value of the hedged currency,  they also limit any gain that might result if the
hedged currency's value increases.

    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  of fering a
lesser rate of exchange on the purchase of that currency.

    The Manager uses forward  contracts for currency  hedging  purposes only and
not for speculative  purposes.  The Funds are not required to enter into forward
contracts with regard to their foreign  holdings and will not do so unless it is
deemed appropriate by the advisor.

     Each  Fund's  assets are valued  daily in U.S.  dollars,  although  foreign
currency  holdings are not  physically  converted  into U.S.  dollars on a daily
basis.

DEPOSITARY RECEIPTS

    American  Depositary  Receipts and European  Depositary Receipts ("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 purc hasing 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 inf ormation and
the market value of the unsponsored ADR or EDR.

RESTRICTED SECURITIES

    Restricted  securities  held by the Funds generally can be sold in privately
negotiated transactions, pursuant to an exemption from registration under the

     4                                      American Century Investments

Securities Act of 1933, or in a registered public offering.  Where  registration
is  required,  a Fund may be required  to pay all or a part of the  registration
expense,  and a  considerable  period may elapse  between the time it decides to
seek  registration  of the securities and the time it is permitted t o sell them
under an effective  registration  statement.  If,  during this  period,  adverse
market conditions were to develop,  the Fund might obtain a less favorable price
than prevailed when it decided to try to register the securities.


SECURITIES LENDING

    Each Fund may lend  portfolio  securities to earn  additional  income.  If a
borrower  defaulted on a securities  loan, 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 Directors:

(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 busines
     s 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 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
     o r 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  Directors  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 t
     he   creditworthiness   of  all  borrowers  with  which  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 Directors.

PUT OPTIONS ON INDIVIDUAL SECURITIES

    Each Fund may buy puts with  respect to stocks  underlying  its  convertible
security  holdings.  For example,  if the Manager  anticipates  a decline in the
price of the stock  underlying  a  convertible  security  a Fund  holds,  it may
purchase a put option on the stock. If the stock price  subsequently  decl ines,
an increase in the value of the put option  could be expected to offset all or a
portion of the  effect of the  stock's  decline on the value of the  convertible
security.

FUTURES AND OPTIONS TRANSACTIONS

     Futures 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 Commodit y Futures
Trading Commission (CFTC), a U.S. government agency.

     Although  futures  contracts,  by their terms,  call for actual delivery or
acceptance of the underlying securi-

     Statement of Additional Information                               5

ties,  in most cases the contracts  are closed out before the  settlement  date.
Closing  out a futures  position  is done by taking an  opposite  position in an
identical  contract  (i.e.,  buying a contract that has previously been sold, or
selling a contract that has previously been bought).

     To initiate and maintain  open  positions in futures  contracts,  a Fund is
required to make a good faith margin  deposit in cash or  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 an additional "variation" margin. Conve rsely, 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  Funds'   investment
restrictions.

     Those who trade  futures  contracts  may be  broadly  classified  as either
"hedgers" or "speculators."  Hedgers use the futures markets primarily to offset
unfavorable  changes in the value of  securities  they hold or expect to acquire
for  investment  purposes.  Speculators  are less  likely to own the sec urities
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.

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

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

     The buyer of a typical  put option can expect to realize a gain if security
prices fall substantially.  However,  if the underlying  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  pai d, plus
related transaction costs).

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

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

     6                                      American Century Investments

has written,  however,  the Fund must  continue to be prepared to pay the strike
price while the option is  outstanding,  regardless of price  changes,  and must
continue to set aside assets to cover its position.

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

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

     COMBINED  POSITIONS.  A Fund may purchase and write options in  combination
with one another, or in combination with futures or forward contracts,  in order
to adjust the risk and  return  characteristics  of the  overall  position.  For
example,  a Fund may  purchase a put option and write a call  option on the same
underlying  instrument in order to construct a combined  position whose risk and
return  characteristics  are  similar to 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 redu ce 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.

     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 (options not traded on exchanges)
generally  are  established  through  negotiation  with the  other p arty to the
option  contract.   While  this  type  of  arrangement  allows  a  Fund  greater
flexibility in tailoring an option to its needs, OTC options  generally  involve
greater credit risk than  exchange-traded  options,  which are guaranteed by the
clearing  organizations  of the  exchanges  where  they are trade d. The risk of
illiquidity is also greater with OTC options because these options generally can
be closed out only by negotiation with the other party to the option.

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

     CORRELATION OF PRICE CHANGES. Price changes of a Fund's futures and options
positions  may  not  be  well   correlated  with  price  changes  of  its  other
investments.  This may be because of differences  between the underlying indexes
and the types of securities  the Fund invests in. For example,  if a Fund sold a
broad-based index futures contract to hedge against a stock market decline while
completing sales of specific securities in its investment portfolio,  the prices
of the  securities  could move in a different  direction  than the broad  market
index  represented  by the index  futures  contract.  In th e case of an S&P 500
futures contract  purchased by a Fund, either in anticipation of stock purchases
or in an effort to be fully invested, failure of the contract to track the Index
accurately could hinder the Fund from achieving its investment objective.

     Options  and  futures  prices  can also  diverge  from the  prices of their
underlying  instruments  even if the  underlying  instruments  match the  Fund's
investments.  Options and futures prices are affected by factors such as current
and  anticipated  short-term  interest  rates,  changes  in  volatility  of  the
underlying instru-

     Statement of Additional Information                               7

ment, and the time remaining until expiration of the contract; these factors may
not affect security prices the same way.  Imperfect  correlation may also result
from  differing  levels of demand in the  options  and  futures  markets and the
securities markets, from structural  differences in how options a nd futures and
securities are traded, or from the imposition of daily price fluctuation  limits
or trading halts. A Fund may purchase or sell options and futures contracts with
a greater or lesser value than the  securities  it wishes to hedge or intends to
purchase in an effort to compensate  for diff erences in volatility  between the
contract and the securities, although this strategy may not be successful in all
cases.  If price  changes in a Fund's  options or futures  positions  are poorly
correlated  with its  other  investments,  the  positions  may  fail to  produce
anticipated  gains or  result  in loss es that are not  offset by gains in other
investments.

     LIQUIDITY OF FUTURES CONTRACTS AND OPTIONS.  There is no assurance a liquid
secondary market will exist for any particular futures contract or option at any
particular time. Options may have relatively low trading volume and liquidity if
their strike prices are not close to the underlying instru ment's current price.
In addition,  exchanges may establish daily price fluctuation limits for futures
contracts and options and may halt trading if a contract's price moves upward or
downward  more than the limit in a given day. On volatile  trading days when the
price  fluctuation  limit is reached  or a trading  halt is  imposed,  it may be
impossible  for a Fund to  enter  into  new  positions  or  close  out  existing
positions.  If the secondary  market for a contract  were not liquid  because of
price  fluctuation  limits  or  otherwise,  prompt  liquidation  of  unfavorable
positions  could be  difficult or impossi ble, and the Fund could be required to
continue  holding a position until delivery or expiration  regardless of changes
in value. Under these  circumstances,  the Fund's access to assets held to cover
its futures and options positions also could be impaired.

     RESTRICTIONS  ON THE USE OF FUTURES  CONTRACTS  AND OPTION.  The Funds have
filed a notice of eligibility  for exclusion as a "commodity pool operator" with
the CFTC and the National Futures  Association,  which regulates  trading in the
futures markets. The Funds intend to comply with Section 4.5 of t he regulations
under the Commodity Exchange Act, which limits the extent to which the Funds can
commit assets to initial margin deposits and options premiums.

     Each Fund may enter into futures contracts,  options, or options on futures
contracts,  provided  that such  obligations  represent  no more than 20% of the
Fund's  net  assets.  Under the  Commodity  Exchange  Act, a Fund may enter into
futures and options  transactions  for hedging  purposes  without  regard to the
percentage  of assets  committed to initial  margin and option  premiums and for
other than hedging purposes provided that assets committed to initial margin and
option  premiums  do not  exceed 5% of the  Fund's  net  assets.  To the  extent
required by law, each Fund will set aside cash and appropriat e liquid assets in
a segregated  account to cover its obligations  related to futures contracts and
options.

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

     FUTURES AND OPTIONS RELATING TO FOREIGN CURRENCIES.  Each Fund may purchase
and sell currency futures and purchase and write currency options to increase or
decrease  its  exposure  to  different  foreign  currencies.  Each Fund may also
purchase  and write  currency  options in  conjunction  with each othe r or with
currency futures or forward contracts.

     Currency  futures  contracts  are  similar  to  forward  currency  exchange
contracts,   except  that  they  are  traded  on  exchanges   (and  have  margin
requirements) and have standard contract sizes and delivery dates. Most currency
futures contracts call for payment or delivery in U.S. dollars.  The underlyin g
instrument of a currency  option may be a foreign  currency,  which generally is
purchased  or  delivered  in  exchange  for U.S.  dollars,  although it may be a
futures contract. The purchaser of a currency call obtains the right to purchase
the underlying currency,  and the purchaser of a currency put obt ains the right
to sell the underlying currency.

     The uses and risks of currency  futures and options are similar to those of
futures and options  relating to  securities  or indexes,  as  described  above.
Currency futures and option values can be expected to correlate

     8                                      American Century Investments

with exchange rates,  but may not reflect other factors that affect the value of
a  Fund's  investments.   A  currency  hedge,  for  example,  should  protect  a
deutsche-mark-denominated  security from a decline in the deutsche  mark, but it
will  not  protect  the  Fund  against  a  price  decline  resulting  from a det
erioration  in the  issuer's  creditworthiness.  Because  the  value of a Fund's
foreign-currency-denominated investments will change in response to many factors
other  than  exchange  rates,  it may not be  possible  to match  the  amount of
currency  options and futures to the value of the Fund's  foreign  invest  ments
over time.

INVESTMENT RESTRICTIONS

     The Funds' investment  restrictions set forth below are fundamental and may
not be changed  without  approval of a majority of the votes of  shareholders of
the Funds as determined in accordance with the Investment Company Act of 1940.

    EACH FUND MAY NOT:

(1)  With respect to 75% of its total  assets,  purchase the  securities  of any
     issuer (other than securities  issued or guaranteed by the U.S.  government
     or its agencies or instrumentalities)  if, as a result, more than 5% of its
     total assets would be invested in securities of that issuer.

(2)  Purchase  the  securities  of any one  issuer  if  immediately  after  such
     purchase  the Fund  would  hold  more  than 10% of the  outstanding  voting
     securities of that issuer.

(3)  Borrow  money  except  from  a  bank  as a  temporary  measure  to  satisfy
     redemption  requests or for  extraordinary  or emergency  purposes and then
     only in an amount not  exceeding  331&3% of the market  value of the Fund's
     total assets so that immediately after any such borrowing asset coverage of
     at least 300% for all such borrowings exists. To secure any such borrowing,
     the Fund may not mortgage,  pledge,  or hypothecate in excess of 33-1/3% of
     the value of its total  assets.  The Fund will not  purchase  any  security
     while  borrowings  representing  more  than  5% of  its  total  assets  are
     outstanding.  T he Fund may also borrow  money for  temporary  or emergency
     purposes  from  other  funds or  portfolios  for  which  Benham  Management
     Corporation  is the  investment  advisor,  or from a joint  account of such
     funds or portfolios, as permitted by federal regulatory agencies.

(4)  Act as an underwriter of securities issued by others.

(5)  Purchase real estate, real estate mortgage loans,  interests in real estate
     limited  partnerships,  or interests in oil, gas or mineral  exploration or
     development  programs or leases,  provided that this  limitation  shall not
     prohibit  (i) the  purchase of U.S.  Government  securities  and other debt
     securities secured by real estate or interests  therein;  (ii) the purchase
     of marketable securities issued by companies or investment trusts that deal
     in real  estate or  interests  therein;  or (iii)  purchase  of  marketable
     securities  issued by companies or other  entities or  investment  vehicles
     that  en gage  in  businesses  relating  to the  development,  exploration,
     mining, processing or distributing of oil, gas, or minerals.

(6)  Engage  in  any  short-selling   operations   (except  by  selling  futures
     contracts).

(7)  Make  loans to  others,  except for the  lending  of  portfolio  securities
     pursuant  to  guidelines  established  by  the  Board  of  Directors  or in
     connection  with purchase of debt  securities in accordance with the Fund's
     investment  objective and  policies.  The Fund may also lend money to other
     funds o r portfolios  for which the Manager is the investment  advisor,  as
     permitted under investment restriction (3) above.

(8)  Purchase  warrants,  valued at the lower of cost or market, in excess of 5%
     of the value of the Fund's net assets. Included within that amount, but not
     to exceed 2% of the value of the Fund's net assets,  may be warrants  which
     are not  listed  on the New York or  American  Stock  Exchanges.  Warran ts
     acquired by the Fund at any time in units or attached to securities are not
     subject to this restriction.

(9)  Purchase securities on margin, except for such short-term credits as may be
     necessary  for the  clearance of  transactions,  provided that the Fund may
     make initial and variation  margin payments in connection with purchases or
     sales of futures contracts or options on futures contracts.

(10) Invest in securities that are not readily  marketable or the disposition of
     which is restricted

     Statement of Additional Information                               9


     under federal securities laws (collectively "illiquid securities") if, as a
     result, more than 5% of the Fund's net assets would be invested in illiquid
     securities.

(11) Issue or sell any class of senior  security  as defined  in the  Investment
     Company Act of 1940  except for notes or other  evidences  of  indebtedness
     permitted under  investment  restriction (3) above and except to the extent
     that notes evidencing temporary borrowings or the purchase of securities on
     a when-issued or delayed delivery basis might be deemed such.

(12) Except  in  connection  with  a  merger,  consolidation,   acquisition,  or
     reorganization,  invest in the  securities of other  investment  companies,
     including  investment  companies  advised by the Manager,  if,  immediately
     after  such  purchase  or  acquisition,  more  than 10% of the value of the
     Fund's tot al assets would be invested in such  securities in the aggregate
     or more than 5% in any one such security.

(13) Purchase or retain  securities  of any issuer if, to the  knowledge  of the
     Fund's  management,  those  officers  and  Directors of the Fund and of its
     investment  advisor  who  each  own  beneficially  more  than  0.5%  of the
     outstanding securities of such issuer,  together own beneficially more than
     0.5% of such securities.

(14) Invest in securities of an issuer that, together with any predecessor,  has
     been in operation for less than three years if, as a result, more than 0.5%
     of the total assets of the Fund would then be invested in such securities.

(15) Invest in the  securities  of any one  issuer  if,  immediately  after such
     purchase, more than 25% of the Fund's total assets would be invested in the
     securities of issuers  having their  principal  business  activities in the
     same industry.

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

PORTFOLIO TRANSACTIONS

     Each Fund's assets are invested by the Manager in a manner  consistent with
the  Fund's  investment  objectives,  policies  and  restrictions  and  with any
instructions  the Board of  Directors  may issue from time to time.  Within this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement securities  transactions on behalf of the Funds. In placing orders for
the  purchase and sale of  portfolio  securities,  the Manager will use its best
efforts to obtain the best possible price and execution and will otherwise place
orders with  broker-dealers  subject to and in accordance with any  instructions
the Board of  Directors  may issue from time to time.  The  Manager  will select
broker-dealers to execute  portfolio  transactions on behalf of the Funds solely
on the basis of best price and executio n.

     The Funds' annual portfolio turnover rates are not expected to exceed 150%.
Because a higher  turnover  rate  increases  transaction  costs and may increase
taxable capital gains, the advisor  carefully  weighs the potential  benefits of
short-term investing against these considerations.

     The following table illustrates the Funds' portfolio turnover rates for the
fiscal years ended December 31, 1995 and 1994.

VALUATION OF PORTFOLIO SECURITIES

     Each Fund's net asset value per share ("NAV") is calculated as of the close
of business of the New York Stock Exchange (the "Exchange") usually at 3:00 p.m.
Central  time each day the  Exchange  is open for  business.  The  Exchange  has
designated the following  holiday  closings for 1997: New Year's Day (observed),
Presidents'  Day,  Good  Friday,  Memorial  Day,  Independence  Day,  Labor Day,
Thanksgiving  Day, and Christ-mas Day (observed).  Although the Funds expect the
same holiday schedule to be observed in the future,  the Exchange may modify its
holiday schedule at any time.

     The  Manager  typically  completes  its  trading  on behalf of the Funds in
various markets before the Exchange closes for the day. Securities are valued at
market,  depending  upon the  market or  exchange  on which  they  trade.  Price
quotations for exchange-listed  securities are taken from the primary ex changes
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 Excha nge and the Funds'  offices  are not open and
the Funds' net asset values are not calculated.  The Funds' net asset values may
be significantly affected on days when shareholders have no access to the Funds.
Securities for which market quotations are not readily  available,  or which may
change in value due to events  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 Directors.

PERFORMANCE

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

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

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

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

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

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

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

     Statement of Additional Information                              11


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

     The Funds' performance may be compared with the performance of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may  include  comparisons  with funds that,  unlike  American
Century funds,  are sold with a sales charge or deferred sales charg e. 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 (sour ce: 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 municipa l 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 Reso urces, Inc.); the CRB Futures Index (source: Commodity
Index  Report);  the price of gold  (sources:  London  am/pm fixing and New York
Comex Spot Price);  rankings of any mutual fund or mutual fund category  tracked
by Lipper Analytical Services,  Inc. or Morningstar,  Inc.; mutual fund rankings
published in major,  nationally  distributed  periodicals;  data provided by the
Investment Company Institute;  Ibbotson  Associates,  STOCKS,  BONDS, BILLS, AND
INFLATION; major indexes of stock market performance; and indexes and historical
data supplied by major  securities  brokerage or investment  advisory firms. The
Funds may also utilize reprints from newspapers and magazines furnished by third
parties to illustrate historical performance.

     Indexes may assume  reinvestment  of dividends,  but generally  they do not
reflect  administrative  and management costs such as those incurred by a mutual
fund.

     Occasionally  statistics may be used to illustrate Fund volatility or risk.
Measures of volatility or risk  generally are used to compare a Fund's net asset
value or  performance  to a market  index.  One measure of volatility is "beta."
Beta  expresses Fund  volatility  relative to the total market as represented by
the S&P 500.  A beta of more than 1.00  indicates  volatility  greater  than the
market, and a beta of less than 1.00 indicates  volatility less than the market.
Another  measure  of  volatility  or  risk  is  "standard  deviation."  Standard
deviation  is used to measure  variability  of net asset va lue or total  return
relative  to an average  over a  specified  period of time.  The premise is that
greater   volatility   connotes  greater  risk  undertaken  to  achieve  desired
performance.

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

TAXES

     Each Fund intends to qualify annually as a "regulated  investment  company"
under Subchapter M of the Internal Revenue Code of 1986 as amended (the "Code").
By so  qualifying,  a Fund will not be subject to federal and state income taxes
to the  extent  that it  distributes  substantially  all of its ne t  investment
income and net realized capital gains distributed to shareholders.

     Distributions  from the Funds are  taxable to  shareholders  regardless  of
whether they are taken in cash or reinvested in additional  shares.  For federal
income  tax  purposes,  shareholders  receiving  distributions  in the  form  of
additional  shares will have a basis in each such share equal to the Fund 's net
asset value per share on the reinvestment date.

     Distributions of net investment income and net short-term capital gains are
taxable to shareholders as

     12                                     American Century Investments


ordinary  income.  To the extent  that a Fund's  dividends  consist of  dividend
income from  domestic  corporations,  such  dividends  may be  eligible  for the
dividends-received  deduction  available to corporations.  Shareholders  will be
notified annually of the federal tax status of distributions.

     Upon redeeming, selling, or exchanging shares, a shareholder will realize a
taxable gain or loss depending  upon his or her basis in the shares  liquidated.
The gain or loss  generally  will be  long-term or  short-term  depending on the
length of time the shares were held. However, a loss recognized by a shareholder
in the  disposition  of shares on which  capital  gain  dividends  were paid (or
deemed  paid)  before the  shareholder  had held his or her shares more than six
months  would be treated as a long-term  capital loss for tax  purposes.  A gain
realized on the  redemption,  sale, or exchange of shar es would not be affected
by the  reacquisition  of shares.  A loss realized on the  redemption,  sale, or
exchange of shares would be disallowed to the extent that the shares disposed of
were replaced  (whether  through  reinvestment  of  distributions  or otherwise)

     The information  above is only a summary of some of the tax  considerations
affecting the Funds and their shareholders;  no attempt has been made to discuss
individual tax consequences. Shareholders who are neither citizens nor residents
of the U.S. may be subject to a nonresident  alien  withholdin g tax of 30% or a
lower  treaty rate,  depending  on the country in which they reside.  The Funds'
distributions  also  may be  subject  to  state,  local,  or  foreign  taxes.  A
prospective  investor  may wish to consult a tax  advisor to  determine  whether
either Fund is a suitable investment based on his or her tax situation.

ABOUT AMERICAN CENTURY QUANTITATIVE EQUITY FUNDS

     American  Century   Quantitative   Equity  Funds  (the  "Corporation")  was
organized as a California  corporation on December 31, 1987. The Corporation was
formerly  known as Benham Equity Funds.  The  Corporation is authorized to issue
ten series and to issue two billion (2,000,000,000) shares of each suc h series.
Within each  series,  the Board of Directors  may issue an  unlimited  number of
shares.  Currently,  there are five series in the Corporation,  American Century
Income  & Growth  Fund  (formerly  known as  Benham  Income & Growth  Fund)  and
American  Century  Equity  Growth Fund  (formerly  known as Benham Equity Growth
Fund) are described in this Statement of Additional Information. With respect to
each  series,  shares  issued  are  fully  paid  and  nonassessable  and have no
preemptive,  conversion,  or similar rights.  All consideration  received by the
Corporation  for shares of any series,  and all assets,  i ncome,  and gains (or
losses) earned thereon, belong to that series exclusively and are subject to the
liabilities related thereto.

     Shares of each series have equal voting  rights,  provided that each series
votes  separately  on matters that pertain to it  exclusively.  The  Corporation
instituted  dollar-based voting, meaning the number of votes you are entitled to
is  based  upon  the  dollar  value  of  their  investment.  Under  Califor  nia
Corporations Code Section 708,  shareholders have the right to cumulate votes in
the election (or  removal) of  Directors.  For  example,  if six  Directors  are
proposed for election,  a shareholder may cast six votes for a single candidate,
or three votes for each of two candidates, etc.

     As of July 31, 1996,  the officers and  Directors,  as a group,  owned less

INVESTMENT ADVISORY SERVICES

     Each Fund has an investment  advisory agreement with the Manager 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 Funds since each Fund's inception. ACC is a holding company that owns all
of the stock of the operating companies that provide the investment  management,

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.

     Each 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 majori ty of the Fund's
Directors,  including a majority of those  Directors who are neither  parties to

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 Directors.

U.S. GOVERNMENT SECURITIES

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

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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 settlement  date if it is deemed  advisable as a matter of investment
strategy.

In purchasing  securities on a when-issued or forward commitment basis, the Fund
will  establish  and maintain  until the  settlement  date a segregated  account
consisting of cash, cash  equivalents,  or high-quality  securities 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
capital gains or losses.

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,  Benham Management
Corporation  (the  "Manager")  need not sell  such  commitments,  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.

CONVERTIBLE SECURITIES

The  Fund may buy  securities  that  are  convertible  into  common  stock.  The
following is a brief description 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

2                                                   American Century Investments


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 the  underlying  stock.  Warrants  are
issued with expiration  dates.  Once a warrant  expires,  it has no value in the
market.

REPURCHASE AGREEMENTS

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

The manager 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 Directors;

(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
     Directors  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;

(5)  Investing  no more  than  15% of the  Fund's  total  assets  in  repurchase
     agreements that mature in more than seven days; and

(6)  Taking delivery of securities  subject to repurchase  agreement and holding
     them in a segregated 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 Manager, the Fund's
investment  advisor.  Pooled  repos are expected to increase the income the Fund
can earn from repo  transactions  without  increasing the risks  associated with
these transactions.

FOREIGN SECURITIES

Although the Fund may buy securities of foreign issuers in foreign markets, most
of its foreign securities investments are made by purchasing American Depositary
Receipts ("ADR"s), "ordinary shares," or "New York shares" in the U.S.

ADRs are dollar-denominated receipts representing interests in the securities of
a foreign issuer.  They are issued by U.S. banks and traded on exchanges or over
the counter in the U.S.  Ordinary  shares are shares of foreign issuers that are
traded abroad and on a U.S. exchange.  New York shares are shares that a foreign
issuer has allocated for trading in the U.S. ADRs, ordinary shares, and New York
shares all may be purchased with and sold for U.S.  dollars,  which protects the
Fund from the foreign settlement risks described below.

Investing in foreign  companies may involve risks not typically  associated with
investing in U.S.  companies.  The value of  securities  denominated  in foreign
currencies and of dividends from such securities can change  significantly  when
foreign  currencies  strengthen or weaken relative to the U.S.  dollar.  Foreign
securities  markets  generally  have less trading volume and less liquidity than
U.S. markets, and prices in some foreign markets can be very volatile.

Many  foreign  countries  lack  uniform  accounting  and  disclosure   standards
comparable to those that apply to U.S.  companies,  and it may be more difficult

Statement of Additional Information                                            3



to obtain reliable information  regarding a foreign issuer's financial condition
and  operations.  In  addition,  the  costs  of  foreign  investing,   including
withholding  taxes,  brokerage  commissions,  and custodial  fees, are generally
higher than for U.S. investments.

Foreign  markets  may offer less  protection  to  investors  than U.S.  markets.
Foreign  issuers,  brokers,  and  securities  markets  may be  subject  to  less
governmental  supervision.  Foreign security trading practices,  including those
involving  the  release of assets in advance of payment,  may involve  increased
risks in the event of a failed trade or the  insolvency of a  broker-dealer  and
may involve substantial delays. It may also be difficult to enforce legal rights
in foreign countries.

Investing  abroad  carries  political  and economic  risks  distinct  from those
associated  with investing in the U.S.  Foreign  investments  may be affected by
actions  of  foreign  governments  that are  adverse  to the  interests  of U.S.
investors,  including the possibility of  expropriation  or  nationalization  of
assets, confiscatory taxation,  restrictions on U.S. investment, or 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.

The Fund may purchase or sell forward foreign currency exchange contracts. While
these  contracts are not presently  regulated by the Commodity  Futures  Trading
Commission  (CFTC),  the CFTC may in the future  assert  authority  to  regulate
forward  contracts.  In such  event,  the  Fund's  ability  to  utilize  forward
contracts in the manner set forth in the Prospectus  may be restricted.  Forward
contracts  will  reduce  the  potential  gain  from  a  positive  change  in the
relationship  between  the U.S.  dollar and  foreign  currencies.  Unanticipated
changes in currency prices may result in poorer overall performance for the Fund
than if it had not  entered  into such  contracts.  The use of foreign  currency
contracts  will  not  eliminate  fluctuations  in  the  underlying  U.S.  dollar
equivalent  value  of,  or rates of  return  on,  the  Fund's  foreign  currency
denominated portfolio securities and the use of such techniques will subject the
Fund to certain risks.

The matching of the  increase in value of a forward  contract and the decline in
the U.S. dollar equivalent value of the foreign currency  denominated asset that
is the subject of the hedge generally will not be precise. In addition, the Fund
may not always be able to enter  into  foreign  currency  forward  contracts  at
attractive  prices and this will limit the Fund's  ability to use such contracts
to hedge or  cross-hedge  its  assets.  Also,  with  regard to the Fund's use of
cross-hedges, there can be no assurance that historical correlations between the
movement  of  certain  foreign  currencies  relative  to the  U.S.  dollar  will
continue. Thus, at any time, poor correlation may exist between movements in the
exchange rates of the foreign currencies in which the Fund's assets that are the
subject of such cross-hedges are denominated.

The Manager uses forward  contracts for currency  hedging  purposes only and not
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 doing so
is deemed appropriate by the Manager.

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.

INTEREST RATE SWAPS

Swap  transactions  contemplated by the Manager typically would involve entering
into a contract with a broker-dealer  to receive the total returns of a specific
Index  security  or basket of Index  securities  (minus a fee) in  exchange  for
periodic payments based on a money market interest rate index such as the London
Interbank Offered Rate (LIBOR).

The net  amount of the  excess,  if any,  of one  party's  obligations  over its
entitlements  with respect to the interest rate swap agreement  would be accrued
on a daily basis, and an equal amount of cash, cash  equivalents,  or high-grade
liquid debt securities would be maintained in a segregated account by the Fund's
custodian.

The Fund would not enter into an interest rate swap transaction  unless: (1) the
unsecured senior debt or  claims-paying  ability of the other party was rated in
the top two rating  categories  by at least two rating  agencies at the time the
transaction was

4                                                   American Century Investments


entered into, (2) unless it was so rated by one such rating agency if unrated by
the other two, or (3) if unrated by all three,  it was considered by the advisor
to be of comparable quality.

If the other party to a swap transaction defaulted,  the Fund would have certain
contractual  remedies under the agreement but would  nonetheless  bear a risk of
loss of unrealized  income (not principal) in the event of default or bankruptcy
of the broker-dealer.

Certain  restrictions imposed on the Fund by the Internal Revenue Code may limit
the Fund's ability to use swap agreements. The swap market is relatively new and
largely  unregulated.  It is  possible  that  developments  in the swap  market,
including  government  regulation,  could adversely affect the Fund's ability to
terminate  existing  agreements or to realize  amounts to be received under such
agreements.  The Manager  believes  that the swap market is  relatively  liquid.
However, as long as the SEC staff considers swap agreements to be illiquid,  the
Fund intends to treat them as such for purposes of its investment restrictions.

In the event that the  unsecured  senior  debt or  claims-paying  ability of the
other  party to an  interest  rate  swap  transaction  ceased to be rated or was
downgraded  by a rating  agency,  the  Manager  would,  although it would not be
required  to,  sell  or  exchange  such  instrument  within  a  reasonable  time
thereafter, taking into consideration such factors as price, credit risk, market
conditions, interest rates, and other hedging strategies available to the Fund.

GOLD FUTURES CONTRACTS

The Fund may enter  into  contracts  for the  future  delivery  of gold.  A gold
futures  contract  is an  agreement  between  two  parties  to buy and sell gold
bullion on a future date at a specified  price.  The purchaser of a gold futures
contract is bound by the terms of the  contract to pay a fixed price for gold to
be  delivered  on a fixed  date in the  future.  The  seller  of a gold  futures
contract is  obligated to deliver gold on a fixed date in the future in exchange
for a fixed price. Contracts of this type involve daily settlement,  in cash, of
the gain or loss on the underlying gold.  Although futures  contracts,  by their
terms,  require actual delivery and acceptance of the underlying  metal, in most
cases the contracts are closed out before the settlement date.

Gold futures contracts are standardized  obligations traded on major commodities
exchanges.  In the United States,  gold futures contracts trade on the Commodity
Exchange,  Inc. in New York,  the Chicago  Board of Trade,  and the  Mid-America
Commodity  Exchange in Chicago.  Gold futures contracts traded on U.S. commodity
exchanges are subject to regulation by the applicable  exchange and by the CFTC.
The CFTC's mandate is to prevent price  manipulation  and excessive  speculation
and to promote orderly and effective commodity futures markets. CFTC regulations
may include trading, price, and position limits as well as margin requirements.

When the Fund  purchases  or sells a futures  contract,  it  deposits an initial
margin with its custodian equal to a percentage of the contract's  value. If the
value of  either  party's  position  changes,  that  party is  required  to make
maintenance  margin payments to settle the change in value on a daily basis. The
Fund makes a payment if its  futures  position  becomes  less  valuable,  and it
receives a payment if its futures position becomes more valuable.

Positions  in gold  futures  contracts  may be closed out only on an exchange or
board of trade that provides a secondary market for such contracts. Although the
Fund intends to purchase contracts only on national exchanges or boards of trade
where there appears to be an active secondary market, there is no assurance that
a  liquid  secondary  market  will  exist  for any  particular  contract  at any
particular time.

Because  it is  possible  to enter  into a gold  futures  contract  by making an
initial  payment of as little as 5% of the value of the underlying  gold,  these
contracts can involve a high degree of risk. A small decline in the price of the
underlying gold could result in the loss of most or all of the cash invested.

Pursuant to a 1988 undertaking with the State of California, the Fund's combined
margin  deposits on gold futures  contracts  may not exceed 5% of the Fund's net
assets.  The extent to which the Fund enters into gold  futures  contracts  (and
forward foreign currency  transactions) may also be limited by the fact that the
Fund intends to meet Internal Revenue Service  requirements for qualification as
a regulated

Statement of Additional Information                                            5


investment company,  including requirements regarding  diversification of assets
and  qualifying  income.  To assure that the Fund's  investments in gold futures
contracts  do not  involve  leveraging,  cash or cash  equivalents  equal to the
underlying  commodity  value (at the time a contract  is  executed)  of any gold
futures  contract  purchased by the Fund (less related margin  deposits) will be
deposited in a segregated account with the Fund's custodian.

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 Directors:

(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 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  Directors  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.

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 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.

GOLD INVESTMENTS

GOLD  BULLION.  As a  means  of  seeking  its  principal  objective  of  capital
appreciation  and when it is felt to be  appropriate as a possible hedge against
inflation,  the Fund may invest a portion of its assets in gold  bullion and may
hold a portion of its cash in foreign currency in the form of gold coins.  There
is,  of  course,  no  assurance  that  such  investments  will  provide  capital
appreciation as a hedge against inflation.  The Fund's ability to invest in gold
bullion is restricted by

6                                                   American Century Investments


the diversification requirements which the Fund must meet in order to qualify as
a regulated  investment  company under Subchapter M of the Internal Revenue Code
of 1986, as amended (the "Code"), as well as the diversification requirements of
the  Investment  Company Act of 1940, as amended (the "1940 Act").  In addition,
the ability of the Fund to make such  investments  may be further  restricted by
the  securities  laws and  regulations in effect from time to time in the states
where the Fund's  shares are  qualified  for sale.  The Fund has not  previously
invested in gold bullion because of these regulations.  However,  at the date of
this  Statement  of  Additional  Information  there  do  not  appear  to be  any
regulations currently in effect in the states in which the Fund is qualified for
sale prohibiting such purchases.  Accordingly,  if otherwise consistent with the
Fund's objectives, it may purchase gold bullion.

Fund assets will be invested in gold  bullion at such times as the  prospects of
such  investments  are, in the opinion of management,  attractive in relation to
other  possible  investments.  The basic trading unit for gold bullion is a gold
bar weighing  approximately  100 troy ounces with a purity of at least 995/1000,
although gold bullion is also sold in much smaller  units.  Gold bars and wafers
are usually numbered and bear an indication of purity and the stamp of the assay
office which certifies the bar's purity. Bars of gold bullion  historically have
traded  primarily in New York,  London,  and Zurich gold markets and in terms of
volume,  such gold  markets  have been the major  markets  for  trading  in gold
bullion.  Prices in the Zurich gold market generally correspond to the prices in
the London gold market.  Since the ownership of gold bullion became legal in the
United States on December 31, 1974,  U.S.  markets for trading gold bullion have
developed. It is anticipated that transactions in gold will generally be made in
such U.S.  markets,  although such  transactions  may be made in foreign markets
when it is deemed to be in the best interest of the Fund.  Transactions  in gold
bullion by the Fund are negotiated with principal  bullion dealers,  unless,  in
the investment's  manager's opinion,  more favorable prices (including the costs
and expenses  described  below) are otherwise  obtainable.  Prices at which gold
bullion is purchased or sold include dealer  mark-ups or  mark-downs,  insurance
expenses,  may be a greater or lesser percentage of the price from time to time,
depending on whether the price of gold bullion  decreases  or  increases.  Since
gold bullion does not generate any investment  income, the only source of return
to the Fund on such an investment will be from any gains realized upon its sale,
and negative  return will be realized,  of course,  to the extent the Fund sells
its gold bullion at a loss.

SPECIAL CONSIDERATIONS AS A RESULT OF THE FUND'S
INVESTMENT POLICIES

As is the case  with  respect  to  virtually  all  investments,  there are risks
inherent in the Fund's policies of investing in securities of companies  engaged
in mining,  processing or dealing in gold or other  precious  metals and in gold
bullion.  In  addition  to the  general  considerations  described  above,  such
investments may involve the following special considerations:

FLUCTUATIONS  IN THE PRICE OF GOLD.  The price of gold has recently been subject
to substantial  upward and downward movements over short periods of time and may
be affected by unpredictable international monetary and political policies, such
as  currency  devaluations  or  revaluations,   economic  conditions  within  an
individual country,  trade imbalances or trade or currency  restrictions between
countries and world inflation  rates and interest  rates.  The price of gold, in
turn, is likely to affect the market  prices of securities of companies  mining,
processing,  or  dealing  in gold  and,  accordingly,  the  value of the  Fund's
investments in such securities also may be affected.

POTENTIAL  EFFECT OF  CONCENTRATION OF SOURCE OF SUPPLY AND CONTROL OF SALES. At
the  current  time there are only four major  sources of supply of primary  gold
production,  and the market share of each source cannot be readily  ascertained.
One of the  largest  national  producers  of gold  bullion  and  platinum is the
Republic of South Africa. Changes in political and economic conditions affecting
South Africa may have a direct impact on its sales of gold.  Under South African
law, the only  authorized  sales agent for gold  produced in South Africa is the
Reserve Bank of South Africa which, through its retention policies, controls the
time and place of its retention policies, and controls the time and place of any
sale of South African bullion. The South African Ministry of Mines

Statement of Additional Information                                            7


determines gold mining policy. South Africa depends  predominantly on gold sales
for the foreign exchange necessary to finance its imports,  and its sales policy
is  necessarily  subject to national and  international  economic and  political
developments.

TAX AND CURRENCY  LAWS.  Changes in the tax or currency laws of the U.S., and of
foreign countries,  may inhibit the Fund's ability to pursue or may increase the
cost of pursuing its investment  programs.  For example,  in September 1985, the
government  of South Africa  reimposed a two-tier  currency  system.  While this
system  may be  removed  within  the next  couple  of  years,  it  continues  to
differentiate  between  currency  which  may be used in  transactions  involving
transfers of South African  investments  by foreign  investors  (the  "financial
rand") and currency used for importing goods and remitting profits and dividends
from an operating enterprise ( the "commercial rand"). Since the reimposition of
the  two-tier  currency  system,  the  volatility  of  the  financial  rand  has
contributed to  fluctuations  in the net asset value of the Fund.  These effects
may increase if the permissible uses of the financial rand are expanded.

UNPREDICTABLE MONETARY POLICIES,  ECONOMIC AND POLITICAL CONDITIONS.  The Fund's
assets  might be less  liquid or the change in the value of its assets  might be
more volatile (and less related to general price movements in the U.S.  markets)
than  would be the case  with  investments  in the  securities  of  larger  U.S.
companies,  particularly because the price of gold and other precious metals may
be affected by unpredictable  international  monetary  policies and economic and
political considerations, governmental controls, conditions of scarcity, surplus
or  speculation.  In addition,  the use of gold or Special Drawing Rights (which
are also used by members of the  International  Monetary Fund for  international
settlements) to settle net deficits and surpluses in trade and capital movements
between nations subject the supply and demand,  and therefore the price, of gold
to a variety of economic  factors which normally would not affect other types of
commodities.

NEW AND DEVELOPING MARKETS FOR PRIVATE GOLD OWNERSHIP. Between 1933 and December
31,  1974,  a market  did not exist in the United  States in which gold  bullion
could be purchased by individuals for investment purposes. Since it became legal
to invest in gold,  markets have  developed  in the U.S. Any large  purchases or
sales of gold  bullion  could  have an  effect  on the  price  of gold  bullion.
Recently,  several  Central  Banks have been  sellers of gold bullion from their
reserves. Sales by central banks and/or rumors of such sales have had a negative
effect on gold prices.

EXPERTISE OF THE INVESTMENT  MANAGER.  The  successful  management of the Fund's
portfolio may be more  dependent upon the skills and expertise of its investment
manager than is the case for most mutual  funds  because of the need to evaluate
the  factors  identified  above.   Moreover,  in  some  countries,   disclosures
concerning an issuer's financial  condition and results and other matters may be
subject to less stringent regulatory  provisions,  or may be presented on a less
uniform  basis than is the case for  issuers  subject to U.S.  securities  laws.
Issuers  and  securities  exchanges  in some  countries  may be  subject to less
stringent governmental regulations than is the case for U.S. companies.

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  votes  of
shareholders of the Fund as determined in accordance with the 1940.

THE FUND MAY NOT:

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

(2)  Borrow  money,  except  that the Fund may  borrow  money for  temporary  or
     emergency  purposes  (not for  leveraging or  investment)  in an amount not
     exceeding 331/3% of the Fund's total assets (including the amount borrowed)
     less  liabilities  (other than  borrowings).  Any  borrowings  that come to
     exceed this amount will be reduced within three days (not including Sundays
     and holidays) to the extent necessary to comply with the 331/3% limitation.

(3)  Lend any security or make any other loan if, as a result,  more than 331/3%
     of the Fund's  total  assets would be lent to other  parties,  except,  (i)
     through  the  purchase  of a  portion  of an  issue of debt  securities  in
     accordance with its investment objective, policies and limitations, or (ii)
     by engaging in repurchase agreements with 

8                                                   American Century Investments


     respect to portfolio securities.

(4)  Purchase or sell real estate  unless  acquired as a result of  ownership of
     securities or other  instruments  (but this shall not prevent the fund from
     investment  in  securities  or other  instruments  backed by real estate or
     securities of companies engaged in the real estate business).

(5)  Deviate from its policy of  concentrating  its investments in securities of
     issuers  engaged in mining,  fabricating,  processing or dealing in gold or
     other precious metals, such as silver, platinum and palladium.

(6)  Act as  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.

The Fund is also subject to the following  restrictions that are not fundamental
and may,  therefore,  be changed by the Board of Directors  without  shareholder
approval.

THE FUND MAY NOT:

(a)  Purchase the securities of any one issuer (other than securities  issued or
     guaranteed   by  the   U.S.   government   or  any  of  its   agencies   or
     instrumentalities)  if, as a result  thereof,  the Fund would own more than
     10% of its outstanding voting securities of such issuer.

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

(c)  Except  in  connection  with  a  merger,  consolidation,   acquisition,  or
     reorganization,  invest in the  securities of other  investment  companies,
     including  investment  companies  advised by the Manager,  if,  immediately
     after  such  purchase  or  acquisition,  more  than 10% of the value of the
     Fund's total assets would be invested in such securities.

(d)  Purchase gold bullion,  gold coins, or gold  represented by certificates of
     ownership  interest or gold futures  contracts whose  underlying  commodity
     value would cause the Fund's  aggregate  investment in such  commodities to
     exceed 10% of the Fund's net assets.

(e)  Invest in securities of an issuer that, together with any predecessor,  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.

(f)  Purchase warrants,  valued at the lower of cost or market, in excess of 10%
     of the Fund's net  assets.  Included in that amount but not to exceed 2% of
     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.

(g)  Invest in oil, gas or other mineral exploration or development  programs or
     leases.

(h)  Sell securities short, unless it owns or has the right to obtain securities
     equivalent in kind and amount to the  securities  sold short,  and provided
     that  transaction  in  futures  contracts  and  options  are not  deemed to
     constitute selling securities short.

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

(j)  Lend assets other than  securities to other parties,  except by (a) lending
     money  (up to 5% of the  Fund's  net  assets)  to a  registered  investment
     company or  portfolio  for which its  investment  adviser  or an  affiliate
     serves as investment adviser or (b) acquiring loans, loan participation, or
     other  forms  of  direct  debt  instruments  and in  connection  therewith,
     assuming  any  associated  unfunded  commitments  of  the  sellers.   (This
     limitation  does not apply to purchases of debt securities or to repurchase
     agreements.)

(k)  Purchase the  securities  of any issuer if, to the  knowledge of the Fund's
     management,  those officers and Directors of the Fund and of its investment
     advisor,  who each  own  beneficially  more  than  0.5% of the  outstanding
     securities  of

Statement of Additional Information                                            9


     such issuer, together own more than 5% of such issuer's securities.

(l)  Purchase or sell options of any kind.

PORTFOLIO TRANSACTIONS

The Fund's  assets are invested by the Manager in a manner  consistent  with the
Fund's  investment   objective,   policies  and   restrictions,   and  with  any
instructions  the Board of  Directors  may issue from time to time.  Within this
framework,  the Manager is responsible for making all  determinations  as to the
purchase and sale of portfolio  securities and for taking all steps necessary to
implement  securities  transactions on behalf of 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  Directors  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 is not expected to exceed 100%.  The
table below illustrates the Fund's portfolio turnover rates for the fiscal years
ended December 31, 1995 and 1994.

Fiscal Period                   Portfolio Turnover Rates
- -------------------------------------------------------------
1995                                     28.40%
1994                                     41.67%
- -------------------------------------------------------------

Brokerage  commissions  paid by the Fund during the fiscal years ended  December
31, 1995, 1994, and 1993, are indicated in the following table.

Fiscal Period                     Brokerage Commissions

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

VALUATION OF PORTFOLIO SECURITIES

The Fund's net asset value per share  ("NAV") is  calculated  as of the close of
business of the New York Stock Exchange (the  "Exchange"),  usually at 3:00 p.m.
Central  time each day the  Exchange  is open for  business.  The  Exchange  has
designated the following  holiday  closings for 1997: New Year's Day (observed),
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.

The  Manager  typically  completes  its trading on behalf of the Fund in various
markets before the Exchange closes for the day. Securities are valued at market,
depending upon the market or exchange on which they trade.  Price quotations for
exchange-listed  securities are taken from the primary  exchanges on which these
securities  trade.  Stocks  traded on exchanges or  over-the-counter  are valued
according to last sale prices,  if such prices are available,  or at the current
bid price.  Fixed-income  securities  are priced at market value on the basis of
market quotations  supplied by independent  pricing  services.  Foreign currency
exchange rates are also determined  prior to the close of the Exchange.  Trading
of securities in foreign markets may not take place on every day the Exchange is
open,  and trading takes place in various  foreign  markets on days on which the
Exchange  and the Fund's  offices are not open and the Fund's net asset value is
not calculated. The Fund's net asset value may be significantly affected on days
when  shareholders  have no  access  to the Fund.  Securities  for which  market
quotations are not readily available, or which may change in value due to events
occurring  after their  primary  exchange  has closed for the day, are valued at
fair market value as  determined  in good faith under the direction of the Board
of Directors.

PERFORMANCE

The Fund's  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.

Total returns reflect all aspects of the Fund's return,  including the effect of
reinvesting  dividends  and  capital  gain  distributions  and any change in the
Fund's net asset value per share during the period.

Average annual total returns are calculated by determining the growth or decline
in value  of a  hypothetical  historical  investment  in the Fund  over a stated
period and then calculating the annually compounded

10                                                  American Century Investments


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

The Fund's  average  annual  total  returns  for the  one-year,  five-year,  and
life-of-fund periods ended June 30, 1996, are indicated in the table below.

Fiscal Period                 Average Annual Total Returns
- --------------------------------------------------------------
One Year                                  3.93%
Five Year                                 7.98%
Life of Fund*                             3.66%
- --------------------------------------------------------------

* The Fund commenced operations on August 17, 1988.

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)  in order 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 the American
Century funds, are sold with a sales charge or deferred sales charge. Sources of
economic data that may be used for such comparisons 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 tax-free municipal  securities (source:  Telerate);  yield curves
for foreign government securities (sources: Bloomberg Financial Markets and Data
Resources,  Inc.); total return on foreign bonds (source: J.P. Morgan Securities
Inc.);  various  U.S.  and  foreign  government  reports;  the junk bond  market
(source: Data Resources,  Inc.); the CRB Futures Index (source:  Commodity Index
Report); the price of gold (sources: London am/pm fixing and New York Comex Spot
Price);  rankings of any mutual fund or mutual fund  category  tracked by Lipper
Analytical Services,  Inc. or Morningstar,  Inc.; mutual fund rankings published
in major,  nationally distributed  periodicals;  data provided by the Investment
Company Institute;  Ibbotson  Associates,  Stocks,  Bonds, Bills, and Inflation;
major  indexes of stock  market  performance;  and indexes and  historical  data
supplied by major  securities  brokerage or investment  advisory firms. The 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.

The Fund's  sales  literature  may  illustrate  the  market for gold  within the
context of historical and current economic  conditions.  Specific  illustrations
may  include  the  relationship  of the price of gold (per  London pm fixing) to
30-year U.S. Treasury bond yields, 30-year U.S. Treasury bond prices,  inflation
as measured by the Consumer Price Index, or equity securities as measured by the
Standard & Poor's 500  Composite  Stock  Price  Index (S&P 500) or the Dow Jones
Industrial Average.

Occasionally,  statistics  may be used to  illustrate  Fund  volatility or risk.
Measures  of  volatility  or risk are  generally  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

Statement of Additional Information                                           11


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 the  variability of net asset value or total return
relative  to an average  over a  specified  period of time.  The premise is that
greater   volatility   connotes  greater  risk  undertaken  to  achieve  desired
performance.

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

TAXES

The Fund intends to qualify annually as a "regulated  investment  company" under
the Code.  By so  qualifying,  the Fund will not be  subject to federal or state
income  taxes  on its net  investment  income  and net  realized  capital  gains
distributed to shareholders.

Distributions  from the Fund are taxable to  shareholders  regardless of whether
they are taken in cash or reinvested in additional  shares.  For federal  income
tax purposes,  shareholders  receiving  distributions  in the form of additional
shares  will have a basis in each such share equal to the Fund's net asset value
per share on the reinvestment date.

Distributions  of net  investment  income and net  short-term  capital gains are
taxable to  shareholders  as ordinary  income.  The Board of Directors  does not
expect to declare  dividends  on a regular  basis.  However,  to the extent that
dividends  are declared  and to the extent that they consist of dividend  income
from   domestic   corporations,   such   dividends   may  be  eligible  for  the
dividends-received  deduction  available to corporations.  Shareholders  will be
notified annually of the federal tax status of distributions.

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  long-term  or  short-term,
depending on the length of time shares were held.  However, a loss recognized by
a shareholder in the  disposition of shares on which capital gain dividends were
paid (or deemed paid) before the shareholder had held his or her shares for more
than six months would be treated as a long-term capital loss for tax purposes. A
gain  realized on the  redemption,  sale,  or  exchange  of shares  would not be
affected by the  reacquisition  of shares.  A loss  realized on the  redemption,
sale,  or exchange of shares would be  disallowed  to the extent that the shares
disposed of were replaced  (whether  through  reinvestment of  distributions  or
otherwise)  within a period of 61 days  beginning  30 days  before and ending 30
days after the date shares were disposed of. Under such circumstances, the basis
of the shares acquired would be adjusted to reflect the disallowed loss.

Earnings  derived by the Fund from  sources  outside the U.S.  may be subject to
non-U.S.  withholding  and possibly other taxes.  Such taxes might be reduced or
eliminated  under the terms of a U.S.  income  tax  treaty,  and the Fund  would
undertake any procedural  steps required to claim the benefits of such a treaty.
With respect to any non-U.S.  taxes actually paid by a Fund, if more than 50% of
the value of the Fund's total  assets at the close of any taxable year  consists
of securities of foreign corporations, the Fund will elect to treat any non-U.S.
income  and  similar  taxes  it  pays  as  though  the  taxes  were  paid by its
shareholders.

Generally,  a credit for foreign taxes is subject to the limitation  that it may
not exceed the shareholder's  U.S. tax attributable to his or her taxable income
from foreign  sources.  Gains  realized by the Fund from the sale of  securities
will be  treated as derived  from U.S.  sources,  and  certain  currency  gains,
including gains from foreign-currency-denominated debt securities,  receivables,
and  payables,  will be  treated  as  income  derived  from  U.S.  sources.  The
limitation  on the foreign tax credit is applied  separately  to foreign  source
passive income,  which may include certain dividends  received from the Fund and
certain other types of income. Accordingly,  shareholders may be unable to claim
a credit for the full amount of their  proportionate  share of the foreign taxes
paid by the Fund.

Gains  attributable to the disposition of the Fund`s direct  investments in gold
bullion  or  coins  do  not  qualify  as  income  for  purposes  of   satisfying
diversification  tests under the Code. If the Fund realizes  greater than 10% of
its income from such non-qualifying sources, the Fund would incur federal income
and state taxes on the net investment income and capital gains it distributes to
shareholders.

The information above is only a summary of some

12                                                  American Century Investments


of the tax  considerations  affecting the Fund and its shareholders;  no attempt
has been made to  discuss  individual  tax  consequences.  Shareholders  who are
neither citizens nor residents of the U.S. may be subject to a nonresident alien
withholding tax of 30% or a lower treaty rate, depending on the country in which
they reside. The Fund's  distributions  also may be subject to state,  local, or
foreign taxes. To determine  whether the Fund is a suitable  investment based on
his or her tax  situation,  a  prospective  investor  may wish to  consult a tax
advisor.

ABOUT AMERICAN CENTURY QUANTITATIVE EQUITY FUNDS

American Century  Quantitative  Equity Funds (the "Corporation") is a registered
open-end  management  investment  company  that was  organized  as a  California
corporation  on December 31, 1987.  The  Corporation  was formerly  known as the
Benham Equity  Funds.  The  Corporation  is authorized to issue 10 series and to
issue  two  billion  (2,000,000,000)  shares of each such  series.  Within  each
series,  the  Board of  Directors  may  issue an  unlimited  number  of  shares.
Currently,  there are five series in the  Corporation,  American  Century Global
Gold Fund  (formerly  known as Benham  Global Gold Fund and Benham Gold Equities
Index  Fund) is decribed  in this  Statement  of  Additional  Information.  With
respect to each series,  shares issued are fully paid and nonassessable and have
no preemptive,  conversion, or similar rights. All consideration received by the
Corporation  for shares of any  series,  and all assets,  income,  and gains (or
losses) earned thereon, belong to that series exclusively and are subject to the
liabilities related thereto.

Shares of each series have equal voting rights,  provided that each series votes
separately on matters that pertain to it exclusively. The Corporation instituted
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 Directors is
determined  by the votes  received  from all of the  Corporation's  shareholders
without  regard  to  whether  a  majority  of  shareholders  voted in favor of a
particular  nominee or all nominees of a group.  Under California  Corporation's
Code Section 708,  shareholders have the right to cumulate votes in the election
(or removal) of Directors.  For example, if six Directors are up for election, a
shareholder may cast six votes for a single  candidate,  three votes for each of
two candidates, etc.

INVESTMENT ADVISORY SERVICES

The Fund has an investment  advisory  agreement with the Manager,  dated June 1,
1995, that was approved by the Fund`s 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 family
of 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  shares,  or by vote of a majority of the Fund's  Directors,
including a majority of those Directors 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.

The investment  advisory agreement  stipulates that the Manager will provide the
Fund with investment advice and portfolio management services in accordance with
the Fund's investment objective,  policies, and restrictions. The agreement also
provides that the Manager will determine what  securities  will be purchased and
sold by the Fund and assist the Fund's  officers in carrying out decisions  made
by the Board of Directors.

Under the  investment  advisory  agreement,  the Fund pays the Manager a monthly
investment advisory fee equal to its pro rata share of the dollar amount derived
from  applying  the  Corporation's  average  daily net  assets to the  following
investment advisory fee rate schedule:

     .50% of the first $100 million;  
     .45% of the next $100 million; 
     .40% of the next $100 million;
     .35% of the next $100 million;  
     .30% of the next $100 million;  
     .25% of the next $1 billion; 
     .24% of the next $1 billion; 
     .23% of the next $1 billion;  
     .22% of the next $1 billion;  
     .21% of the next $1 billion; 
     .20% of the next $1 billion; and
     .19% of average daily net assets over $6.5 billion.

Investment  advisory  fees paid by the Fund to the Manager for the fiscal  years
ended December 31,

pays ACS a monthly fee equal to its pro rata share of the dollar amount  derived
from  applying the average  daily net assets of all of the Funds  advised by the
Manager to the following administrative fee rate schedule:

Statement of Additional Information                                            1

INVESTMENT POLICIES AND TECHNIQUES

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

The Fund may purchase and sell indexed  securities and may engage in futures and
options  transactions  for investment as well as hedging  purposes to the extent
permitted by applicable law. Indexed securities,  as described below, are a type
of investment security and, accordingly, may fluctuate in value.

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

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)  that 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 Directors;

(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
     Directors  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;

(5)  Investing  no  more  than  15% of  the  Fund's  net  assets  in  repurchase
     agreements that mature in more than seven days; and

(6)  Taking  delivery of all  securities  subject to a 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 its 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).

In purchasing  securities on a when-issued or forward commitment basis, the Fund
will establish and

2                                                   American Century Investments


maintain until the settlement date a segregated account consisting of cash, cash
equivalents,  or  high-quality  securities  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 capital gains or losses.

On the  settlement  date,  the market  value of the security may be more or less
than its  purchase  or sale price under the  agreement.  If the other party to a
when-issued  or  forward  commitment  agreement  fails to deliver or pay for the
security, the Fund could miss a favorable price or yield opportunity or suffer a
loss.  The  Fund  does not earn  interest  on  purchased  securities  until  the
settlement date.

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

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 a Fund's  total  assets to be
committed under when-issued or forward commitment  agreements,  the Manager 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%.
However,  the  Manager  need not  sell  such  commitments.  In  addition,  as an
operating policy, the Fund will not enter into when-issued or forward commitment
transactions with settlement dates exceeding 120 days.

CONVERTIBLE SECURITIES

The Fund may buy securities that are convertible into common stock. Listed below
is a 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 provide  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

Statement of Additional Information                                            3


issuer's financial condition and operations.  In addition,  the costs of foreign
investing,  including withholding taxes,  brokerage  commissions,  and custodial
fees, are generally higher than for U.S. investments.

Foreign  markets  may offer less  protection  to  investors  than U.S.  markets.
Foreign  issuers,  brokers,  and  securities  markets  may be  subject  to  less
governmental  supervision.  Foreign security trading practices,  including those
involving  the  release of assets in advance of payment,  may involve  increased
risks in the event of a failed trade or the  insolvency of a  broker-dealer  and
may involve substantial delays. It may also be difficult to enforce legal rights
in foreign countries.

Investing  abroad  carries  political  and economic  risks  distinct  from those
associated  with investing in the 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 a future date and
price. By entering into a forward  contract to buy or sell the amount of foreign
currency involved in a security  transaction for a fixed amount of U.S. dollars,
the advisor can protect the Fund against losses  resulting from adverse  changes
in the relationship between the U.S. dollar and the foreign currency between the
date the security is purchased or sold and the date on which  payment is made or
received.  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.

The Fund uses forward  contracts for currency  hedging purposes only and not 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.

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.

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 or if the value of the

4                                                   American Century Investments


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 Directors:

(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 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  Directors  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.

FOREIGN CURRENCY EXCHANGE TRANSACTIONS

The Manager may engage in foreign  currency  exchange  transactions on behalf of
the Fund in order to manage currency risk.  Foreign currencies will be purchased
and sold  regularly,  either in the spot (i.e.,  cash)  market or in the forward
market  (through  forward  foreign  currency  exchange  contracts,  or  "forward
contracts").

A forward  foreign  currency  exchange  contract is an obligation to purchase or
sell a specific currency at a future date, which may be any fixed number of days
agreed upon by the parties, commencing with the date of the contract, at a price
set at the time of the contract.  When the Fund agrees to buy or sell a security
denominated in a foreign currency, it may enter into a forward contract to "lock
in" the U.S. dollar price of the security.  By entering into a forward  contract
for the purchase or sale, for a fixed amount of U.S.  dollars,  of the amount of
foreign currency involved in the underlying securities transaction,  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  subject  foreign  currency
between the date the  security is purchased or sold and the date payment is made
or received.  This type of transaction  is sometimes  referred to as a "position
hedge."

Successful use of forward  contracts depends on the Manager's skill in analyzing
and predicting currency values.  Although they are used for settlement purposes,
forward  contracts alter the Fund's exposure to currency  exchange rate activity
and  could  result in losses to the Fund if  currencies  do not  perform  as the
Manager  anticipates.  The Fund may also incur significant costs when converting
assets from one currency to another.

Statement of Additional Information                                            5


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.

NON-SECTOR EQUITY SECURITIES

The Fund may invest in companies engaged in the natural resources  industry that
do not meet all of the criteria for inclusion in the Energy and Basic  Materials
sectors (excluding chemical companies) of the Dow Jones World Stock Index. These
may include small companies that do not meet the capitalization  requirement for
inclusion in the Energy and Basic  Materials  sectors  ("Sectors")  but that the
Manager believes represent significant investment opportunities for the Fund.

Within this category, the Manager attempts to select securities of issuers whose
revenues and earnings are expected to be  influenced by changes in the prices of
natural  resources  and that are expected to perform in a manner that causes the
Fund s performance to closely track the performance of the Sectors.

DEPOSITARY RECEIPTS

American  Depositary  Receipts  ("ADR"s)  and European  Depositary  Receipts and
("EDR"s) are receipts representing  ownership of a foreign-based issuer's shares
held in trust by a bank or similar financial institution. These are designed for
the U.S.  and European  securities  markets as  alternatives  to the purchase of
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.

FUTURES AND OPTIONS TRANSACTIONS

Futures  Transactions.  The  Fund  may  engage  in  futures  transactions.  Such
transactions  may be  used to  maintain  cash  reserves  while  remaining  fully
invested,  to facilitate  trading,  to reduce  transaction  costs,  or to pursue
higher  investment  returns when a futures contract is priced more  attractively
than its underlying security or index.

Futures  contracts  provide  for the sale by one party and  purchase  by another
party of a security  at a  specified  future  time and price.  Although  futures
contracts,  by their terms,  generally call for actual delivery or acceptance of
the underlying securities, in most cases the contracts are closed out before the
settlement date. The Fund can close out a futures position 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.

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

Some futures  contract  strategies carry a substantial risk of loss, due to both
the low margin  deposits  required  and the high degree of leverage  involved in
futures pricing. A relatively small movement in a futures contract may result in
immediate, substantial gains or losses to the Fund.

Although  techniques other than trading futures contracts can be used to control
a Fund's exposure to market fluctuations,  the use of futures contracts may be a
more  effective  means of hedging this  exposure.  While the 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.

6                                                   American Century Investments


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

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

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

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

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

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

COMBINED POSITIONS.  The Fund may purchase and write options in combination with
one another or in  combination  with  futures or forward  contracts  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 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-

Statement of Additional Information                                            7


counter  ("OTC")  options  (options  not  traded  on  exchanges)  generally  are
established  through  negotiation  with the other party to the option  contract.
While this type of arrangement allows the Fund greater  flexibility in tailoring
an option to its needs, OTC options  generally  involve greater credit risk than
exchange-traded  options,  which are guaranteed by the clearing organizations of
the exchanges  where they are traded.  The risk of  illiquidity  is also greater
with OTC  options  because  these  options  generally  can be closed out only by
negotiation with the other party to the option.

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

CORRELATION  OF PRICE  CHANGES.  Because there are a limited  number of types of
exchange-traded   futures  and  options   contracts,   it  is  likely  that  the
standardized   contracts   available  will  not  match  the  Fund's  current  or
anticipated  investments  exactly.  The Fund may invest in futures  and  options
contracts  based on securities  with  different  issuers,  maturities,  or other
characteristics than the securities in which they typically invest (for example,
hedging  intermediate-term  securities with a futures contract based on an index
of  long-term  bond  prices);  this  strategy  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,
all of 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  and  options  are  similar to those of
futures and options  relating to  securities  or indexes,  as  described  above.
Currency futures' and options' values can be expected to correlate with exchange
rates,  but may not reflect other  factors (such as exchange  rates) that affect
the value of 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. It may not always be possible to
match currency futures to the Fund's foreign securities holdings.

RISKS AND LIQUIDITY OF FUTURES  CONTRACTS AND OPTIONS.  Futures and options have
risks  associated  with their use:  possible  default by the other  party to the
transaction;  illiquidity;  and, to the extent the Manager's  interpretation  of
certain  market  movements  is  incorrect,   the  risk  that  the  use  of  such
transactions  could  result in losses  greater  than if they had not been  used.
Losses resulting from the use of these transactions would reduce net asset value
and possibly income.

There is no assurance a liquid  secondary  market will exist for any  particular
futures contract or option at any particular time. Options may have a 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 the value of the  position.  Under  these
circumstances,  the Fund's access to assets held to cover future positions could
also be impaired.

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

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

The Fund may enter into futures  transactions  (including  related  options) for
hedging purposes without regard to the percentage of assets committed to initial
margin and for other than hedging  purposes  provided  that assets  committed to
initial margin deposits on such instruments, plus premiums paid for open futures
options   positions,   less  the  amount  by  which  any  such   positions   are
"in-the-money,"  do not  exceed 5% of the  Fund's  total  assets.  To the extent
required by law, the Fund will set aside cash and appropriate liquid assets in a
segregated  account to cover its  obligations  related to futures  contracts and
options.  Financial  futures  or options  purchased  or sold by the Fund will be
standardized  and traded through the facilities of a U.S. or foreign  securities
association or listed on a U.S. or foreign  securities or commodities  exchange,
board of trade, or similar entity,  or quoted on an automatic  quotation system,
except that the Fund may effect  transactions in  over-the-counter  options with
primary U.S.  government  securities  dealers  recognized by the Federal Reserve
Bank of New  York.  In  addition,  the Fund has  undertaken  to limit  aggregate
premiums  paid on all  options  purchased  by the Fund to no more than 5% 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  capital  gains  from  the  sale  of
securities  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.

INDEXED SECURITIES

The Fund may invest in indexed  securities whose value is linked to commodities,
including,  but not limited to,  notes  indexed to the Goldman  Sachs  Commodity
Index  (GSCI).  The GSCI is composed  of energy,  agricultural,  livestock,  and
metals  commodities.  The Fund may invest in notes indexed to the entire GSCI or
to certain components of the GSCI.

A commodity-linked note enables the investor to purchase a note whose coupons or
redemption  value is linked to the performance of a particular  commodity price.
The Fund may purchase and sell indexed  securities  for  investment  purposes as
well as hedging  purposes to the extent  permitted by  applicable  law.  Indexed
securities may have return characteristics  similar to direct investments in the
underlying  commodity  or to one or more  options on the  underlying  commodity.
Indexed securities may be more volatile than the underlying commodity itself and
present

Statement of Additional Information                                            9


many of the same risks as investing in futures and options.  Indexed  securities
are also subject to credit risks associated with the issuer of the security.

The Fund  may  invest  in  indexed  securities  to track  the  Sectors  at lower
transaction  costs  or  to  take  advantage  of  investment   opportunities  not
represented by the Sectors.

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  votes of the
shareholders of the Fund as determined in accordance with the Investment Company
Act of 1940 (the "1940 Act").

THE FUND MAY NOT:

(1)  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 may borrow money for temporary or emergency  purposes
     from other funds or portfolios for which Benham  Management  Corporation is
     the investment advisor or from a joint account of such funds or portfolios,
     as permitted by federal regulatory agencies.

(2)  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.

(3)  Purchase or sell real estate,  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
     securities  related to the real estate business);  physical  commodities or
     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 indexes of
     such  securities  or  currencies,   or  any  other  financial  instruments;
     purchasing and selling options on such futures contracts;  and investing in
     securities or other instruments backed by physical commodities.

(4)  Make  loans to  others,  except for the  lending  of  portfolio  securities
     pursuant to  guidelines  established  by the Board of Directors  and except
     those  otherwise in  accordance  with the Fund's  investment  objective and
     policies.

(5)  Issue senior securities, except as permitted under the 1940 Act.

(6)  Purchase  any  security  if, as a result,  25% or more of the Fund's  total
     assets will be invested in the securities of issuers having their principal
     business in the same  industry,  except that the Fund will invest more than
     25% of its  assets  in  securities  of  issuers  in the  natural  resources
     industry.  This limitation does not apply to securities  issued 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 Directors  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

10                                                  American Century Investments


     (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,  or  except  in  connection  with  a  merger,
     consolidation, acquisition, or reorganization.

(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 for 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 the Fund has
complied with its investment restrictions.

PORTFOLIO TRANSACTIONS

The Fund's  assets are invested by the Manager in a manner  consistent  with the
Fund's   investment   objectives,   policies  and   restrictions  and  with  any
instructions  from the Board of Directors  that may be issued from time to time.
Within this framework,  the Manager is responsible for making all determinations
relating 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 with  broker-dealers  orders subject to and in accordance
with any  instructions  the Board of Directors may issue from time to time.  The
Manager will select  broker-dealers to execute portfolio  transactions on behalf
of the Fund solely on the basis of best price and execution.

The Fund's  annual  portfolio  turnover  rate is not  expected  to exceed  100%.
Because a higher  turnover  rate  increases  transaction  costs and may increase
taxable capital gains, the advisor  carefully  weighs the potential  benefits of
short-term  investing  against  these  considerations.  There  was no  portfolio
turnover for the period from September 15, 1994  (commencement  of  operations),
through  December 31, 1994.  The Fund`s  portfolio  turnover rate for the period
ended December 31, 1995 was 39%.

VALUATION OF PORTFOLIO SECURITIES

The Fund's net asset value per share  ("NAV") is  calculated  as of the close of
business of the New York Stock  Exchange (the  "Exchange")  usually at 3:00 p.m.
Central  time each day the  Exchange  is open for  business.  The  Exchange  has
designated the following  holiday  closings for 1997: New Year's Day (observed),
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.

The  Manager  typically  completes  its trading on behalf of the Fund in various
markets before the Exchange closes for the day. Securities are valued at market,
depending upon the market or exchange on which they trade.  Price quotations for
exchange-listed  securities are taken from the primary  exchanges on which these
securities  trade.  Securities  traded on exchanges will be valued at their last
sale prices.  If no sale is reported,  the mean between the latest bid and asked
prices is used.  Securities traded  over-the-counter  will be valued at the mean
between the latest bid and asked prices.  Fixed-income  securities are priced at
market value on the basis of market quotations  supplied by independent  pricing
services.  Trading of securities in foreign  markets may not take place on every
day the Exchange is open, and trading takes place in various  foreign markets on
days on which the  Exchange  and the 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

Statement of Additional Information                                           11


due to events occurring after their primary exchange has closed for the day, are
valued at fair market value as  determined  in good faith under the direction of
the Board of Directors.

PERFORMANCE

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

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

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

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

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

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

In addition to average  annual total returns,  the Fund may quote  unaveraged or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Average annual and cumulative total returns may be quoted
as a  percentage  or as a  dollar  amount  and may be  calculated  for a  single
investment,  a series of investments,  or a series of redemptions  over any time
period.  Total  returns may be broken down into their  components  of income and
capital  (including  capital  gains  and  changes  in share  price)  in order to
illustrate the  relationship of these factors and their  contributions  to total
return.  Performance information may be quoted numerically or in a table, graph,
or similar illustration. The Fund's average annual total return for the one-year
and  life-of-fund  periods  ended June 30, 1996,  are indicated in the following
table.

                                                     Average Annual Total Return

* The Fund commenced operations on September 15, 1994.

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 considered in making such comparisons may include, but
are not limited to, U.S. Treasury bill, note, and bond yields, money market fund
yields, U.S.  government debt and percentage held by foreigners,  the U.S. money
supply,  net free reserves,  and yields on  current-coupon  Government  National
Mortgage  Association  securities  (GNMAs)  (source:  Board of  Governors of the
Federal Reserve System);  the federal funds and discount rates (source:  Federal

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 coupon interest or dividends, but, generally,
they do not reflect  administrative  and management costs such as those incurred
by a mutual fund.

Statistics  may be  used in  advertising  and  sales  literature  to  illustrate
historical and projected demand for commodities  owned or processed by companies
in which the Fund invests.  This may include  illustrations such as a chart that
shows  historical and projected  demand for multiple energy sources  measured in
barrels of oil equivalents, or "BOEs."

Occasionally  statistics  may be used to  illustrate  Fund  volatility  or risk.
Measures  of  volatility  or risk  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 the variability
of net asset  value or total  return  relative  to an average  over a  specified
period of time.  The premise is that greater  volatility  connotes  greater risk
undertaken to achieve desired performance.

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

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

TAXES

The Fund will be  treated  as a  separate  corporation  for  federal  income tax
purposes,  and 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 or state income
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  distributions  declared by the Fund in December  and paid in January of the
following year are taxable as if they were paid on December 31st.

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 sold at the Fund's fiscal year end),
which may cause the Fund to recognize income without  receiving  sufficient cash
for making distributions in amounts necessary to satisfy the 90% and

Statement of Additional Information                                           13


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 other instruments,
gains or losses  attributable to fluctuations in the value of a foreign currency
between  the  date the  security  or  contract  is  acquired  and the date it is
disposed of are also usually treated as ordinary  income or loss.  Under Section
988 of the Code,  these gains or losses may  increase or decrease  the amount of
the Fund's  investment  company  taxable income  distributed to  shareholders as
ordinary income.

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 if at least one-half of its assets
constitute  investment-type  assets  or  75% or  more  of its  gross  income  is
investment-type  income.  Certain  distributions  from a PFIC and gains from the
sale  of  PFIC  shares  are  treated  as  excess  distributions.   These  excess
distributions  and gains may be subject to federal income tax.  Interest charges
may also be imposed on the fund with respect to deferred taxes arising from such
excess distributions or gains.

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  certain  income  from PFIC  shares,  the  amount  that must be
distributed to  shareholders,  which will be taxed to  shareholders  as ordinary
income or long-term  capital gain,  may be increased or decreased  substantially
compared to that of a fund that did not invest in PFIC shares.

Earnings  derived by the Fund from  sources  outside the U.S.  may be subject to
non-U.S.  withholding  and possibly other taxes.  Such taxes might be reduced or
eliminated  under the terms of a U.S.  income  tax  treaty,  and the Fund  would
undertake any procedural  steps required to claim the benefits of such a treaty.
With respect to any non-U.S.  taxes actually paid by a Fund, if more than 50% of
the value of the Fund's total  assets at the close of any taxable year  consists
of securities of foreign corporations, the Fund will elect to treat any non-U.S.
income  and  similar  taxes  it  pays  as  though  the  taxes  were  paid by its
shareholders.

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

Some of the debt  securities  may be  purchased  by 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  that it does not
exceed the accrued  market  discount on such debt  security.  Generally,  market
discount  accrues on a daily basis for each day the debt security is held by the
Fund and at a  constant  rate  over the time  remaining  to the debt  security's
maturity or, at the election of the Fund,  at a constant  yield to maturity that
takes into account the semiannual compounding of interest.

Generally,  the Fund  will be  required  to  distribute  dividends  representing
discounts  on debt  securities  that  are  currently  includable  in  income  to
shareholders, even if cash representing such income has not been received by the
Fund. Cash to pay such divi-

14                                                  American Century Investments


dends may be obtained from proceeds of sales of securities held by the Fund.

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

TAXATION OF U.S. SHAREHOLDERS

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

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

TAXATION OF NON-U.S. SHAREHOLDERS

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

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

If the  shareholder is not engaged in a U.S. trade or business,  or the payments
received from the Fund are not effectively  connected with the conduct of such a
trade or  business,  the  shareholder  will  generally  be subject  to U.S.  tax
withholding at the rate of 30% (or a lower rate under an applicable  U.S. income
tax  treaty)  on  distributions  of  net  investment  income  and  net  realized
short-term  capital gain received.  Non-U.S.  shareholders not engaged in a U.S.
trade or business or having no effectively  connected income may also be subject
to  U.S.  taxes  at the  rate  of 30% (or a lower  treaty  rate)  on  additional
distributions as a result of the Fund's election to treat any non-U.S.  taxes it
pays as though the taxes were paid by its shareholders.

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

The  information  above  is only a  summary  of  some of the tax  considerations
affecting  the Fund and its  shareholders;  no attempt  has been made to discuss
individual tax consequences.  The Fund and its distributions may also be subject
to state, local, or foreign taxes.  Prospective  investors may wish to consult a
tax advisor to determine whether the Fund is a suitable  investment  relative to
their tax situation.

ABOUT AMERICAN CENTURY QUANTITATIVE EQUITY FUNDS

American Century  Quantitative Equity Funds (the "Corporation") was organized as
a California  corporation on December 31, 1987. The Corporation,  formerly known
as Benham  Equity  Funds,  is  authorized  to issue 10  series  and to issue two
billion (2,000,000,000) shares of each series. Within each series, the Directors
may issue an unlimited number of shares. Currently, there are five series in the
Corporation.  American Century Global Natural Resources Fund,  formerly known as
Benham Global  Natural  Resources  Index Fund, is described in this Statement of
Additional  Information.  With respect to each series,  shares  issued are fully
paid and  nonassessable and have no preemptive,  conversion,  or similar rights.
All consideration  received by the Corporation for shares of any series, and all
assets,  income,  and gains (or losses)  earned  thereon,  belong to that series
exclusively and are subject to the liabilities related thereto.

Shares of each series have equal voting rights,  provided that each series votes
separately on matters  affecting  only that series.  The number of votes you are
entitled to is based upon the dollar value of your  investment  as of the record
date for a shareholder meeting. Under California  Corporations Code Section 708,
shareholders  have the right to cumulate  votes in the  election (or removal) of
Directors.   For  example,  if  six  Directors  are  proposed  for  election,  a
shareholder may cast six votes for a single candidate or three votes for each of
two candidates, etc.

INVESTMENT ADVISORY SERVICES

The Fund has an investment  advisory  agreement with the Manager,  dated June 1,
1995, that was approved by the Fund's 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  either of a majority of the
Fund's  Directors,  including  a majority  of those  Directors  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
which  securities  will be purchased  and sold by the Fund.  It also assists the
Corporation's officers in carrying out decisions made by the Board of Directors.

For these services,  the Fund pays the Manager a monthly investment advisory fee
equal to the sum of two components:  (i) a group fee based on the  Corporation's
average  daily net  assets and (ii) an  individual  fund fee based on the Fund's
average  daily  net  assets.   The  group  fee  is  derived  from  applying  the
Corporation's average daily net assets to the schedule in the next column:

     .50% of the first $100 million;  
     .45% of the next $100 million; 
     .40% of the next $100 million;  
     .35% of the next $100 million;  
     .30% of the next $100 million;  
     .25% of the next $1 billion; 
     .24% of the next $1 billion; 
     .23% of the next $1 billion;  
     .22% of the next $1 billion;  
     .21% of the next $1 billion; 
     .20% of the next $1 billion; and
     .19% of average daily net assets over $6.5 billion.

The  individual  fund fee is derived from applying the Fund's  average daily net
assets to the following schedule of annualized rates:

     .05% of the first $500 million;  
     .04% of the next $500 million; and 
     .03% of the next $1 billion.

No investment  advisory fees have been paid by the Fund to the Manager since the
inception of the Fund in September 1994.

TRANSFER AND ADMINISTRATIVE SERVICES

American Century Services Corporation,  4500 Main Street, Kansas City, Missouri,
64111, (ACS) acts as transfer, administrative services and dividend paying agent
for the Fund. ACS provides  facilities,  equipment and personnel to the Fund and
is paid for such services by the Fund.  For  administrative  services,  the Fund
pays ACS a monthly fee equal to its pro rata share of the dollar amount  derived
from  applying the average  daily net assets of all of the Funds  advised by the
Manager to the following administrative fee rate schedule:

Group Assets                        Administrative Fee Rate
- ----------------------------------------------------------------------
up to $4.5 billion                            .11%
up to $6 billion                              .10
up to $9 billion                              .09
over  $9 billion                              .08
- ----------------------------------------------------------------------

For transfer agent services, the Fund pays ACS a monthly fee of $1.1875 for each
shareholder account

18                                                  American Century Investments


maintained  and $1.35 for each  shareholder  transaction  executed  during  that
month.

For  the  fiscal  year  ended  December  31,  1995,  the  Fund  paid  $7049  for
administrative  services and $62,844 for transfer agent  services.  The fee paid
for administrative services was reduced by a fee waiver of $14,030.

DISTRIBUTION OF FUND SHARES

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

DIRECT FUND EXPENSES

The Fund pays certain operating  expenses that are not assumed by the Manager or
ACS. These include fees and expenses of the  independent  Directors;  custodian,
audit,  tax  preparation  and pricing fees;  fees of outside counsel and counsel
employed   directly  by  the   Corporation;   costs  of  printing   and  mailing
prospectuses,  statements of additional information, proxy statements,  notices,
confirmations,  and reports to  shareholders;  fees for  registering  the Fund's
shares under federal and state securities  laws;  brokerage fees and commissions
(if any);  trade  association  dues;  costs of fidelity and liability  insurance
policies  covering the Fund; costs for incoming WATS lines maintained to receive
and handle shareholder inquiries; and organizational costs.

EXPENSE LIMITATION AGREEMENT

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,  the Fund's
expenses  were less than the  expense  limitation  in effect at that  time.  The
Manager has agreed  under  contract to limit the Fund's  expenses to .75% of the
Fund's  average daily net assets until May 31, 1997.  The expense  limitation is
subject to annual renewal.  The Manager  absorbed $93,050 of the Fund's expenses
for the fiscal year ended December 31, 1995.

VOLUNTARY  EXPENSE  LIMITATION.  As a  supplement  to  the  contractual  expense
guarantee  rate,  the  Manager  voluntarily  agreed to absorb  all of the Fund`s
expenses through December 31, 1994. The Manager`s  voluntary expense limitations
are not  eligible  for  recoupment  (as  described  above  with  respect  to the
contractual expense limitation agreement).

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

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

American  Century may reject or limit the amount of an investment to prevent any
one shareholder or affiliated  group from  controlling the Corporation or one of
its  series;  to avoid  jeopardizing  a series'  tax  status;  or  whenever,  in
management's  opinion,  such rejection is in the Corporation's or a series' best
interest.  As of July 31, 1996, Charles Schwab & Co., 101 Montgomery Street, San
Francisco,  California  94104,  was the omnibus  record holder of  1,756,372.463
shares or 39.1% of the Fund's outstanding shares.

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

Share purchases and redemptions are governed by California law.

under the Investment  Advisers Act of 1940 since December 14, 1971. The Fund has

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 Directors.

U.S. GOVERNMENT SECURITIES

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

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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 settlement  date if it is deemed  advisable as a matter of investment
strategy.

In purchasing  securities on a when-issued or forward commitment basis, the Fund
will  establish  and maintain  until the  settlement  date a segregated  account
consisting of cash, cash  equivalents,  or high-quality  securities 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
capital gains or losses.

As an operating  policy,  the Fund will not commit greater 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  Benham
Management  Corporation (the "Manager") need not sell such  commitments,  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.

CONVERTIBLE SECURITIES

The Fund may buy  securities  that are  convertible  into common stock shares of
utility  companies.  Listed below is a brief description 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 if 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  

2                                                   American Century Investments


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 the  underlying  stock.  Warrants  are
issued with expiration  dates.  Once a warrant  expires,  it has no value in the
market.

REPURCHASE AGREEMENTS

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

The Manager 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 Directors;

(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
     Directors  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;

(5)  Investing  no  more  than  15% of  the  Fund's  net  assets  in  repurchase
     agreements that mature in more than seven days; and

(6)  Taking delivery of securities subject to a repurchase agreement and holding
     them in a segregated 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 Manager.  Pooled
repos  are  expected  to  increase  the  income  the  Fund can  earn  from  repo
transactions without increasing the risks associated with these transactions.

FOREIGN SECURITIES

Although the Fund may buy securities of foreign issuers in foreign markets, most
of its foreign securities investments are made by purchasing American Depositary
Receipts ("ADR"s),  "ordinary shares," or "New York shares." The Fund may invest
in  foreign-currency-denominated  debt or equity securities of companies engaged
in the utilities  industry if the Manager believes that such investments will be
advantageous to the Fund.

ADRs are dollar-denominated receipts representing interests in the securities of
a foreign issuer.  They are issued by U.S. banks and traded on exchanges or over
the counter in the U.S.  Ordinary  shares are shares of foreign issuers that are
traded abroad and on a U.S. exchange.  New York shares are shares that a foreign
issuer has allocated for trading in the U.S. ADRs, ordinary shares, and New York
shares all may be purchased with and sold for U.S.  dollars,  which protects the
Fund from the foreign settlement risks described below.

Investing in foreign  companies may involve risks not typically  associated with
investing in U.S.  companies.  The value of  securities  denominated  in foreign
currencies and of dividends from such securities can change  significantly  when
foreign  currencies  strengthen or weaken relative to the U.S.  dollar.  Foreign
securities  markets  generally  have less trading volume and less liquidity than
U.S. markets, and prices in some foreign markets can be very volatile.

Many  foreign  countries  lack  uniform  accounting  and  disclosure   standards
comparable to those that

Statement of Additional Information                                            3


apply  to  U.S.  companies,  and it may be more  difficult  to  obtain  reliable
information regarding a foreign issuer's financial condition and operations.  In
addition, the costs of foreign investing, including withholding taxes, brokerage
commissions, and custodial fees, are generally higher than for U.S. investments.

Foreign  markets  may offer less  protection  to  investors  than U.S.  markets.
Foreign  issuers,  brokers,  and  securities  markets  may be  subject  to  less
governmental  supervision.  Foreign security trading practices,  including those
involving  the  release of assets in advance of payment,  may involve  increased
risks in the event of a failed trade or the  insolvency of a  broker-dealer  and
may involve substantial delays. It may also be difficult to enforce legal rights
in foreign countries.

Investing  abroad  carries  political  and economic  risks  distinct  from those
associated  with investing in the U.S.  Foreign  investments  may be affected by
actions  of  foreign  governments  that are  adverse  to the  interests  of U.S.
investors,  including the possibility of  expropriation  or  nationalization  of
assets, confiscatory taxation,  restrictions on U.S. investment, or 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 a future date and
price. By entering into a forward  contract to buy or sell the amount of foreign
currency involved in a security  transaction for a fixed amount of U.S. dollars,
the advisor 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  (i.e.,  the spread)  between the
prices at which they are buying and  selling  various  currencies.  A dealer may
offer to sell a foreign  currency  at one rate while  simultaneously  offering a
lesser rate of exchange on the purchase of that currency.

The Manager uses forward  contracts for currency  hedging  purposes only and not
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 this
procedure is deemed appropriate by the Manager.

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.

DEPOSITARY RECEIPTS

American  Depositary  Receipts and  European  Depositary  Receipts  ("EDR"s) are
receipts  representing  ownership  of shares of a  foreign-based  issuer held in
trust by a bank or similar  financial  institution.  These are designed for U.S.
and  European  securities  markets  as  alternatives  to  purchasing  underlying
securities in their corresponding national markets and currencies. ADRs and EDRs
can be sponsored or unsponsored.

Sponsored  ADRs  and  EDRs  are  certificates  in  which  a  bank  or  financial
institution participates with a custodian.  Issuers of unsponsored ADRs and EDRS
are not contractually  obligated to disclose material  information in the United
States.  Therefore,  there may not be a correlation between such information and
the market value of the unsponsored ADR or EDR.

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.

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 or 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 Directors:

(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) above.  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 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  Directors  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.

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 advisor
anticipates  a  decline  in the  price of the  stock  underlying  a  convertible
security  the Fund holds,  it may purchase a put option on the stock or sell the
stock short. If the stock price subsequently declines, the proceeds of the short
sale or an increase  in the value of the put option  could be expected to offset
all or a  portion  of the  effect  of the  stock's  decline  on the value of the
convertible security.

When the  Fund  enters  into a short  sale,  it will be  required  to set  aside
securities equivalent in kind and

Statement of Additional Information                                            5


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

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

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

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

The features of call options are  essentially  the same as those of put options,
except that the purchaser of a call option obtains the right to purchase,

6                                                   American Century Investments


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,  it would be likely that the
writer would 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
one another,  or in combination with futures or forward  contracts,  in order to
adjust the risk and return characteristics of the overall position. For example,
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 a futures  contract.  Another  possible
combined  position  would involve  writing a call option at one strike price and
buying a call  option  at a lower  price,  in order  to  reduce  the risk of the
written  call  option  in the event of a  substantial  price  increase.  Because
combined  options  positions  involve  multiple  trades,  they  result in higher
transaction costs and may be more difficult to open and close out.

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

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

Statement of Additional Information                                            7



CORRELATION  OF PRICE  CHANGES.  Because there are a limited  number of types of
exchange-traded   options  and  futures   contracts,   it  is  likely  that  the
standardized   contracts   available  will  not  match  the  Fund's  current  or
anticipated  investments  exactly.  The Fund may invest in options  and  futures
contracts based on securities with issuers, maturities, or other characteristics
different  from  those  of the  securities  in which it  typically  invests  for
example, it may hedge intermediate-term securities with a futures contract based
on an index of  long-term  bond  prices or hedge  stock  holdings  with  futures
contracts  on a  broad-based  stock  index  such as the  Standard  & Poor's  500
Composite  Stock Price Index (S&P 500) which involves a risk that the options or
futures position will not track the performance of the Fund's other investments.

Options and futures prices can also diverge from the prices of their  underlying
instruments,  even if the underlying  instruments  are well  correlated with the
Fund's  investments.  Options and futures prices are affected by factors such as
current and anticipated  short-term interest rates, changes in the volatility of
the  underlying  instrument,  and the time  remaining  until  expiration  of the
contract;  these  factors  may not  affect  security  prices  in the  same  way.
Imperfect  correlation  may also result from  differing  levels of demand in the
options  and  futures  markets  and  the  securities  markets,  from  structural
differences in how options and futures and  securities  are traded,  or from the
imposition  of daily price  fluctuation  limits or trading  halts.  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 strategy may not be successful in all cases. If price
changes in the Fund's options or futures  positions are poorly  correlated  with
its other  investments,  the positions may fail to produce  anticipated gains or
result in losses that are not offset by gains in other investments.

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  increases or
decreases more than the limit in a given day. On volatile  trading days when the
price  fluctuation  limit is reached  or a trading  halt is  imposed,  it may be
impossible  for 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 and options positions also could be impaired.

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 extent to which the Fund can commit  assets to initial  margin  deposits and
options premiums.

The Fund may enter  into  futures  contracts,  options,  or  options  on futures
contracts,  provided  that such  obligations  represent  no more than 20% of the
Fund's net assets.  Under the  Commodity  Exchange  Act, the Fund may enter into
futures and options  transactions  for hedging  purposes  without  regard to the
percentage  of assets  committed to initial  margin and option  premiums and for
other than hedging  purposes,  provided that assets  committed to initial margin
and option  premiums  do not exceed 5% of the Fund's net  assets.  To the extent
required by law, the Fund will set aside cash and appropriate liquid assets in a
segregated  account to cover its  obligations  related to futures  contracts and
options.

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

8                                                   American Century Investments


included in this 30% calculation, which may limit the Fund's investments in such
instruments.

FUTURES AND OPTIONS  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 each other or with
currency futures or forward contracts.

Currency futures contracts are similar to forward currency  exchange  contracts,
except that they are traded on exchanges (and have margin requirements) and have
standard contract sizes and delivery dates. Most currency futures contracts call
for payment or delivery in U.S. dollars. The underlying instrument of a currency
option may be a foreign  currency,  which generally is purchased or delivered in
exchange for U.S. dollars,  although it may be a futures contract. The purchaser
of a currency call obtains the right to purchase the  underlying  currency,  and
the  purchaser  of a  currency  put  obtains  the  right to sell the  underlying
currency.

The uses and risks of  currency  futures  and  options  are  similar to those of
futures and options  relating to  securities  or indexes,  as  described  above.
Currency  futures and options  values can be expected to correlate with exchange
rates but may not  reflect  other  factors  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.     Because    the    value    of    the    Fund's
foreign-currency-denominated investments will change in response to many factors
other  than  exchange  rates,  it may not be  possible  to match  the  amount of
currency options and futures to the value of the Fund's investments over time.

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  votes of the
shareholders of the Fund as determined in accordance with the Investment Company
Act of 1940 (the "1940 Act").

THE FUND MAY NOT:

(1)  With respect to 75% of its total  assets,  purchase the  securities  of any
     issuer (other than securities  issued or guaranteed by the U.S.  government
     or its agencies or instrumentalities)  if, as a result, (a) more than 5% of
     its total assets would be invested in securities of that issuer, or (b) the
     Fund would hold more than 10% of the outstanding  voting securities of that
     issuer.

(2)  Issue senior  securities,  except as permitted under the Investment Company
     Act of 1940.

(3)  Borrow money except for temporary or emergency purposes (not for leveraging
     or investment) in an amount exceeding 331/3% of its total assets (including
     the  amount  borrowed)  less  liabilities  (other  than  borrowings).   Any
     borrowings  that exceed this amount will be reduced  within three days (not
     including  Sundays and holidays) to the extent necessary to comply with the
     331/3% limitation.

(4)  Underwrite  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.

(5)  Purchase or sell real estate  unless  acquired as a result of  ownership of
     securities  or other  instruments  (but this will not prevent the Fund from
     investing in securities or other  instruments  backed by real estate or the
     securities of companies engaged in the real estate business).

(6)  Purchase  or sell  physical  commodities  unless  acquired  as a result  of
     ownership of securities or other instruments (but this will not prevent the
     Fund from  purchasing  or selling  options  and futures  contracts  or from
     investing  in   securities   or  other   instruments   backed  by  physical
     commodities).

(7)  Lend any security or make any other loan if, as a result,  more than 331/3%
     of its total  assets  would be lent to other  parties,  provided  that this
     restriction does not apply to purchases of debt securities or to repurchase
     agreements.

The Fund is also subject to the following  restrictions that are not fundamental
and may  therefore  be changed  by the Board of  Directors  without  shareholder
approval.

Statement of Additional Information                                            9

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  futures  contracts  and  options  are not deemed to
     constitute selling securities short.

(b)  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 will not constitute  purchasing  securities on
     margin.

(c)  Purchase  any  security  if, as a result,  more than 15% of its net  assets
     would be invested  in  securities  that are  illiquid by virtue of legal or
     contractual  restrictions  on resale or the absence of a readily  available
     market.

(d)  Purchase  securities  of other  investment  companies,  except  in the open
     market where no commission except the ordinary broker's  commission is paid
     or  purchase  or  retain  securities  issued by other  open-end  investment
     companies.  These  restrictions  do not  apply to  securities  received  as
     dividends,  through offers of exchange, or as a result of a reorganization,
     consolidation, or merger.

(e)  Purchase  securities  of  any  issuer  (other  than  securities  issued  or
     guaranteed  by domestic or foreign  governments  or political  subdivisions
     thereof)  if,  as a  result,  more  than 5% of its  total  assets  would be
     invested  in  the  securities  of  business   enterprises  that,  including
     predecessors,  have a  record  of  less  than  three  years  of  continuous
     operation.

(f)  Purchase  warrants,  valued at the lower of cost or market, in excess of 5%
     of the Fund's net assets.  Included in that amount, but not to exceed 2% of
     the Fund's net assets,  may be warrants that are not listed on the New York
     Stock Exchange or the American  Stock  Exchange.  Warrants  acquired by the
     Fund  in  units  or  attached  to  securities  are  not  subject  to  these
     restrictions.

(g)  Invest in oil, gas, or other mineral exploration or development programs or
     leases.

(h)  Purchase the  securities  of any issuer if those  officers and Directors of
     the Fund and those  officers and Directors of the Manager who  individually
     own more than 1/2 of 1% of the securities of such issuer  together own more
     than 5% of such issuer's securities.

(i)  Invest in securities of real estate  investment trusts that are not readily
     marketable or invest in securities of real estate limited partnerships that
     are not  listed  on the New  York  Stock  Exchange  or the  American  Stock
     Exchange or traded on the NASDAQ National Market System.

(j)  Purchase  any security  when  borrowings  representing  more than 5% of its
     total assets are outstanding.

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.

RISK FACTORS

Because  the  Fund  concentrates  its  assets  in the  utilities  industry,  its
performance  depends in part on how favorably  investors perceive this sector of
the market relative to other sectors (such as transportation or technology).  Of
course,  investor  perceptions of the utilities  industry are driven not only by
comparisons  with other  market  sectors  but by trends  and  events  within the
utilities industry.  The following is a brief outline of risk factors associated
with investment in the utilities industry.

REGULATORY RISKS.  Regulators (primarily at the state level) monitor and control
public  utility  company  revenues and costs.  Regulators  can limit profits and
dividends  paid to investors;  they may also restrict a company's  access to new
markets.  Some analysts observe that state  regulators have become  increasingly
active in developing and promoting energy policy through the regulatory process.

NATURAL RESOURCE RISKS. Swift and unpredictable  changes in the price and supply
of natural resources can hamper utility company profitability. These changes may
be caused by political  events,  energy  conservation  programs,  the success of
exploration

10                                                  American Century Investments


projects, or tax and other regulatory policies of various governments.

ENVIRONMENTAL  RISKS. There are considerable costs associated with environmental
compliance,   nuclear  waste  cleanup,  and  safety  regulation.   For  example,
coal-burning  utilities  are under  pressure to curtail  sulfur  emissions,  and
utilities  in  general  increasingly  are  called  upon  by  regulators  to bear
environmental costs, which may not be easily recovered through rate increases or
business growth.

Changing  weather  patterns and natural  disasters  affect  consumer  demand for
utility  services (e.g.,  electricity,  heat, and air  conditioning),  which, in
turn, affects utility revenues.

TECHNOLOGY  AND  COMPETITIVE   RISKS.  The  introduction  and  phase-in  of  new
technologies can affect a utility company's  competitive  strength.  The race by
long-distance  telephone  providers to incorporate fiber optic technology is one
example of competitive risk within the utilities industry.

The increasing role of independent  power producers  ("IPP"s) in the natural gas
and electric  utility  segments of the utilities  industry is another example of
competitive  risk.   Typically,   IPPs  wholesale  power  to  established  local
providers,  but there is a trend  toward  letting  them sell power  directly  to
industrial  consumers.  Co-generation  facilities,  such as  those  of  landfill
operators that produce  methane gas as a byproduct of their core business,  pose
another  competitive  challenge  to gas and electric  utilities.  In addition to
offering a less  expensive  source of power,  these  companies  may receive more
favorable  regulatory treatment than utilities seeking to expand facilities that
consume nonrenewable energy sources.

INTEREST RATE RISKS.  Utility  companies  usually finance  capital  expenditures
(e.g.,  new plant  construction)  by issuing  long-term debt.  Rising  long-term
interest rates increase interest expenses and reduce company earnings.

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  from the Board of Directors  that may be issued 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 otherwise
will place  orders with  broker-dealers  subject to and in  accordance  with any
instructions from the Board of Directors. The Manager will select broker-dealers
to execute  portfolio  transactions on behalf of the Fund solely on the basis of
best price and execution.

The Fund's  annual  portfolio  turnover  rate is not  expected  to exceed  150%.
Because a higher  turnover  rate  increases  transaction  costs and may increase
taxable capital gains, the Manager  carefully  weighs the potential  benefits of
short-term investing against these considerations.

The portfolio turnover rates for the Fund are listed in the table below.

Fiscal Year                   Portfolio Turnover Rate
- --------------------------------------------------------
1995                                           68.17%
1994                                           61.42%
- --------------------------------------------------------

For the fiscal years ended  December 31, 1995,  December 31, 1994,  and December
31,  1993,  the Fund  paid  brokerage  commissions  of  $205,544,  $180,145  and
$266,365, respectively.

VALUATION OF PORTFOLIO SECURITIES

The Fund's net asset value per share  ("NAV") is  calculated  as of the close of
business of the New York Stock Exchange (the  "Exchange"),  usually at 3:00 p.m.
Central  time each day the  Exchange  is open for  business.  The  Exchange  has
designated the following  holiday  closings for 1997: New Year's Day (observed),
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.

The  Manager  typically  completes  its trading on behalf of the Fund in various
markets before the Exchange closes for the day.  Securities are priced at market
value,  depending  upon the  market  or  exchange  on which  they  trade.  Price
quotations for

Statement of Additional Information                                           11


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 every day
the Exchange is open, and trading takes place in various foreign markets on days
on which the  Exchange  and the Fund's  offices  are not open and the Fund's net
asset value is not calculated.  The Fund's net asset value may be  significantly
affected on days when  shareholders  have no access to the Fund.  Securities for
which market quotations are not readily available,  or which may change in value
due to events occurring after their primary exchange has closed for the day, are
valued at fair market value as  determined  in good faith under the direction of
the Board of Directors.

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 an indication of future results.

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

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

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

For the 30-day period ended June 30, 1996, the Fund's yield was 4.11%.

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

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

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

In  addition  to  average  annual  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)  in order to
illustrate the  relationship of these factors and their  contributions  to total
return. The

12                                                  American Century Investments


Fund's  average  annual total return for the one-year and  life-of-fund  periods
ended  June 30,  1996 was 20.91% and  8.53%,  respectively.  The Fund  commenced
operations on March 1, 1993.  Performance  information may be quoted numerically
or in a table, graph, or similar illustration.

The Fund's  performance  may be compared  with the  performance  of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market
performance.  This may  include  comparisons  with funds that,  unlike  American
Century funds, are sold with a sales charge or deferred sales charge. Sources of
economic data that may be considered in making such comparisons may include, but
are not limited to: U.S. Treasury bill, note, and bond yields, money market fund
yields, U.S.  government debt and percentage held by foreigners,  the U.S. money
supply,  net free reserves,  and yields on  current-coupon  Government  National
Mortgage  Association  securities  (GNMAs)  (source:  Board of  Governors of the
Federal Reserve System);  the federal funds and discount rates (source:  Federal
Reserve  Bank of New  York);  yield  curves  for U.S.  Treasury  securities  and
AA/AAA-rated corporate securities (source:  Bloomberg Financial Markets);  yield
curves for AAA-rated tax-free municipal  securities  (source:  Telerate);  yield
curves for foreign government  securities (sources:  Bloomberg Financial Markets
and Data Resources,  Inc.); total returns on foreign bonds (source:  J.P. Morgan
Securities Inc.);  various U.S. and foreign  government  reports;  the junk bond
market (source: Data Resources,  Inc.); the CRB Futures Index (source: Commodity
Index Report); the price of gold (sources:  London a.m./p.m. fixing and New York
Comex Spot Price);  rankings of any mutual fund or mutual fund category  tracked
by Lipper Analytical Services,  Inc. or Morningstar,  Inc.; mutual fund rankings
published in major,  nationally  distributed  periodicals;  data provided by the
Investment Company Institute;  Ibbotson  Associates,  Stocks,  Bonds, Bills, and
Inflation; major indexes of stock market performance; and indexes and historical
data supplied by major  securities  brokerage or investment  advisory firms. The
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 are  generally  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 the  market.  Another  measure  of  volatility  or risk is
"standard  deviation."  Standard deviation is used to measure the variability of
net asset value or total return  relative to an average over a specified  period
of time. The premise is that greater volatility connotes greater risk undertaken
to achieve a desired performance.

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

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

TAXES

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

Distributions  from the Fund are taxable to  shareholders  regardless of whether
they are taken in cash or reinvested in additional  shares.  For federal  income
tax purposes,  shareholders  receiving  distributions  in the form of additional
shares  will have a basis in each such share equal to the Fund's net asset value
per share on the reinvestment date.

Distributions  of net  investment  income and net  short-term  capital gains are
taxable to  shareholders  as  ordinary  income.  To the  extent  that the Fund's
dividends consist of dividend income from domestic

Statement of Additional Information                                           13


corporations,   such  dividends  may  be  eligible  for  the  dividends-received
deduction  available to corporations.  Shareholders will be notified annually of
the federal tax status of distributions.

As of December 31, 1995,  the Fund had a capital  loss  carryover of  $7,035,543
that  will  expire on  December  31,  2002 and  $4,356,683  that will  expire on
December 31, 2003. No capital gain  distributions will be made by the Fund until
its capital loss carryovers have been offset or have expired.

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  long-term  or  short-term,
depending on the length of time the shares were held. However, a loss recognized
by a shareholder  in the  disposition  of shares on which capital gain dividends
were paid (or deemed paid) before the shareholder had held his or her shares for
more than six  months  would be  treated  as a  long-term  capital  loss for tax
purposes.  A gain realized on the redemption,  sale, or exchange of shares would
not  be  affected  by the  reacquisition  of  shares.  A  loss  realized  on the
redemption,  sale,  or exchange of shares would be disallowed to the extent that
the  shares  disposed  of  were  replaced   (whether  through   reinvestment  of
distributions or otherwise)  within a period of 61 days beginning 30 days before
and  ending  30 days  after  the  date  shares  were  disposed  of.  Under  such
circumstances, the basis of the shares acquired would be adjusted to reflect the
disallowed loss.

The  information  above  is only a  summary  of  some of the tax  considerations
affecting  the Fund and its  shareholders;  no attempt  has been made to discuss
individual tax consequences. Shareholders who are neither citizens nor residents
of the U.S. may be subject to a nonresident  alien  withholding  tax of 30% or a
lower  treaty rate,  depending  on the country in which they reside.  The Fund's
distributions  also  may be  subject  to  state,  local,  or  foreign  taxes.  A
prospective  investor may wish to consult a tax advisor to determine whether the
Fund is a suitable investment based on the investor's tax situation.

ABOUT AMERICAN CENTURY QUANTITATIVE EQUITY FUNDS

American Century  Quantitative Equity Funds (the "Corporation") was organized as
a California  corporation  on December 31, 1987.  The  Corporation  was formerly
known as the Benham  Equity  Funds.  The  Corporation  is authorized to issue 10
series  and to issue two  billion  (2,000,000,000)  shares of each such  series.
Within each  series,  the  Directors  may issue an  unlimited  number of shares.
Currently, there are five series in the Corporation.  American Century Utilities
Fund  (formerly  know as Benham  Utilities  Income  Fund) is  described  in this
Statement of Additional Information.  With respect to each series, shares issued
are fully paid and nonassessable and have no preemptive,  conversion, or similar
rights. All consideration  received by the Corporation for shares of any series,
and all assets,  income,  and gains (or losses) earned  thereon,  belong to that
series exclusively and are subject to related liabilities.

Shares of each series have equal voting rights,  provided that each series votes
separately  on matters  that  pertain to it  exclusively.  Each  shareholder  is
entitled to vote based on the total dollar interest in the Fund as of the record
date for a shareholder meeting. Under California  Corporations Code Section 708,
shareholders  have the right to cumulate  votes in the  election (or removal) of
Directors.   For  example,  if  six  Directors  are  proposed  for  election,  a
shareholder may cast six votes for a single  candidate,  three votes for each of
two candidates, etc.
