(1) Redemption proceeds sent by wire are subject to a $10 processing fee.
(2) Estimated.  Benham Management  Corporation (the "Manager") has agreed to limit each Fund's total operating expenses to specified
percentages of each Fund's average daily net assets.  The agreement provides that the Manager may recover amounts absorbed on behalf
of the Fund during the preceding 11 months if, and to the extent that, for any given month, Fund expenses were less than the expense
limit in effect at that time.  The current  expense  limitation for the Fund is .60%.  This expense  limitation is subject to annual
renewal in June, 1997.
</TABLE>

     The Fund pays the Manager  investment  advisory fees equal to an annualized
percentage   of  its  average   daily  net  assets.   Other   expenses   include
administrative  and  transfer  agent  fees  paid to  American  Century  Services
Corporation.
     The purpose of the above table is to help you  understand the various costs
and expenses  that you, as a  shareholder,  will bear  directly or indirectly in
connection  with an investment in the shares of the Fund.  The example set forth
above assumes  reinvestment  of all dividends  and  distributions  and uses a 5%
annual rate of return as required by SEC regulations.
     Neither  the 5% rate of  return  nor the  expenses  shown  above  should be
considered  indications of past or future  returns and expenses.  Actual returns
and expenses may be greater or less than those shown.

4 Information Regarding the Fund                                      Prospectus


                         INFORMATION REGARDING THE FUND
- --------------------------------------------------------------------------------

INVESTMENT POLICIES OF THE FUND
     The Fund has adopted certain investment  restrictions that are set forth in
the  Statement of Additional  Information.  Those  restrictions,  as well as the
investment objective of the Fund identified on page 1 of this Prospectus and any
other  investment  policies  which  are  designated  as  "fundamental"  in  this
Prospectus  or in the  Statement of  Additional  Information,  cannot be changed
without shareholder  approval.  The Fund has implemented  additional  investment
policies and practices to guide its  activities in the pursuit of its investment
objective.  These policies and practices,  which are described  throughout  this
Prospectus,  are not  designated  as  fundamental  policies  and may be  changed
without shareholder approval.

Investment Objective
     The Fund seeks to provide an inflation-protected  rate of return consistent
with investment in U.S. Treasury  inflation-protection  securities.  There is no
assurance that the Fund will achieve its investment objective.

Investment Strategy
     The Fund pursues its investment objective by investing, under normal market
conditions,  at least 65% of its total assets in  securities  that are backed by
the full  faith and  credit of the U.S.  government  and  indexed  or  otherwise
structured  by  the  U.S.  Treasury  to  provide  protection  against  inflation
("TIPS"). TIPS may be issued by the U.S. Treasury in the form of notes or bonds.
The Fund may also invest in U.S.  Treasury  securities  which are not indexed to
inflation for liquidity and tax purposes, or if at any time the manager believes
there is an inadequate supply of appropriate TIPS in which to invest. The Fund's
portfolio may consist of any  combination of these  securities  consistent  with
investment strategies employed by the Manager.
     There are no maturity or duration  restrictions for the securities in which
the Fund may invest. The U.S. Treasury initially is issuing TIPS securities with
a 10 year term to maturity. It has announced its intention (although there is no
guarantee it will do so) to issue additional  securities with a term to maturity
as long as 30  years  and as short  as five  years.  When  these  securities  of
differing  maturity are issued,  the manager  will buy from among the  available
issues  those  securities  that will provide the maximum  relative  value to the
Fund.
     The Fund may be appropriate for investors who are seeking to protect all or
a part of their investment portfolio from the effects of inflation.  Traditional
U.S.  Treasury  fixed-principal  notes and bonds pay a stated  return or rate of
interest in dollars and are redeemed at their par amount.  Inflation  during the
period the securities are outstanding will diminish the future  purchasing power
of these dollars.  The Fund is designed to serve as a vehicle to protect against
this diminishing effect.
     The Fund is not, however,  managed to pursue or provide current income. The
Fund's income yield will likely  reflect "real rates" of interest  (that is, the
then-prevailing  current interest rates minus the  then-prevailing  expectations
for inflation)  available in the Treasury market.  Because these "real rates" of
interest have historically been around 3.5%, the current income generated by the
Fund is expected to be substantially  below that of more traditional  government
securities  funds,  such as Treasury bond funds or government agency bond funds.
The Fund, however,  should benefit as a result of the inflation adjustments that
will be made to its  portfolio  holdings  at  their  final  maturity,  therefore
providing a degree of predictability to the value of the Fund.

5 Information Regarding the Fund                                      Prospectus


     TIPS in which the Fund may invest  are new  securities.  There are  special
investment risks,  particularly share price volatility and potential adverse tax
consequences,  associated with investment in TIPS.  These risks are described in
the following  section.  You should read that section carefully to make sure you
understand the nature of the Fund before you invest in it.

RISK FACTORS AND INVESTMENT TECHNIQUES
     The  obligations  in which the Fund may invest will differ from one another
in their  interest  rates,  maturities,  dates of issuance and interest  payment
schedules.  The pertinent features of the types of obligations in which the Fund
may invest are  described  in this  section.  To the extent that these  features
impact the value of Fund holdings,  they will in turn impact the net asset value
of the Fund.  While the Fund seeks to provide a measure of inflation  protection
to its  investors,  there is no  assurance  that the Fund will provide less risk
than a fund investing in conventional fixed amount treasury securities.

Treasury Inflation-Protection Securities
     TIPS are Treasury securities with a final value and interest payment stream
linked to the  inflation  rate.  TIPS may be issued in either note or bond form.
Treasury  inflation-protection  notes have  maturities of at least one year, but
not more than ten years. Treasury  inflation-protection bonds have maturities of
more than ten years.
     TIPS may be  attractive to investors  seeking an  investment  backed by the
full faith and credit of the U.S. Government that provides a return in excess of
the rate of inflation.  While, according to the U.S. Treasury,  TIPS are modeled
after the "Real Return  Bonds"  currently  issued by the  government  of Canada,
these securities are new to the U.S.  market,  having first been sold in January
1997.  There is  uncertainty as to how these  securities  will be treated by the
marketplace.  See  "Immaturity  of  TIPS  Market"  below.  Inflation  protection
securities  were first auctioned in January 1997 for issuance on January 15. The
securities will be auctioned and issued on a quarterly basis thereafter.

Structure and Inflation Index
     The  principal  value of TIPS will be  adjusted  to reflect  changes in the
level of inflation.  The index for measuring the inflation  rate for TIPS is the
non-seasonally adjusted U.S. City Average All Items Consumer Price Index for All
Urban Consumers  published  monthly by the U.S.  Department of Labor's Bureau of
Labor Statistics.
     Semiannual  coupon interest  payments are made at a fixed percentage of the
inflation-adjusted  principal  value.  The coupon  rate or "real  yield" for the
semiannual interest payment of each issuance of securities will be determined at
the time the securities  are sold to the public.  While a reduction in inflation
will cause a reduction  in the  interest  payment  made on the  securities,  the
repayment of  principal at the maturity of the security  will never be less than
the original face or par amount of the security at issuance.

Indexing Methodology
     The principal value of TIPS will be indexed, or adjusted,  semi-annually to
account for changes in the Consumer  Price Index.  Semi-annual  coupon  interest
payment  amounts  will  be  determined  by  multiplying  the  inflation-adjusted
principal  amount by  one-half  the stated  rate of  interest  on each  interest
payment date.
     The Consumer  Price Index used for the purpose of adjusting  the  principal
value  will be the  index for the  first  day of the  third  month  prior to the
adjustment.  Even if the Bureau of Labor Standards has subsequently revised that
index, the original index will be used. To the extent that

6 Information Regarding the Fund                                      Prospectus


inflation  has  increased  the three months prior to an interest  payment,  that
interest payment will not be protected from the inflation increase.  Further, to
the extent that  inflation  has  increased  during the final  three  months of a
security's  maturity,  the final  value of the  security  will not be  protected
against that increase,  which will negatively  impact the value of the security.
Additionally,  there is disagreement among financial market  professionals as to
whether the Consumer Price Index  actually  reflects the true rate of inflation.
If the market  perceives  that the adjustment  mechanism of the TIPS  securities
does not accurately adjust for inflation, the value of the TIPS securities could
be adversely affected.

Taxation
     Taxation applicable to TIPS is similar to conventional bonds. Both interest
payments   and   the   difference    between   original    principal   and   the
inflation-adjusted  principal  will be treated  as  interest  income  subject to
taxation.  Interest payments are taxable when received or accrued. The inflation
adjustment  to the  principal is subject to tax in the year  adjustment is made,
not at maturity of the security when the cash from the repayment of principal is
received. If an upward adjustment has been made (which typically should happen),
investors in non-tax deferred  accounts will pay taxes on this amount currently.
Decreases in the indexed principal can only be deducted from current or previous
interest payments reported as income.
     TIPS therefore  have a potential cash flow mismatch to an investors,  since
investors  must  pay  taxes  on  the  inflation-adjusted  principal  before  the
repayment of principal is received.  It is possible that,  particularly for high
income tax bracket investors,  TIPS security would not generate enough income in
a given year to cover the tax liability it could create.  This is similar to the
current tax treatment for zero coupon bonds and other discount securities. If an
inflation-protection security is sold prior to maturity, capital losses or gains
are realized in the same manner as traditional bonds. For more information about
taxes and their  affect on you as an investor in the Fund,  see "Taxes," on page
20.

Immaturity of TIPS Market
     The Treasury  securities  market is the largest and most liquid  securities
market in the world.  However,  prior to January  1997,  the  Treasury had never
issued TIPS.  It is  uncertain at this time the extent to which,  if at all, the
Treasury  will support the TIPS market.  Without  Treasury  support,  the market
could be relatively  illiquid or inefficient.  The  marketability of TIPS may be
enhanced over time as the Treasury  issues  additional  TIPS and more  investors
participate in the market.
     The secondary  market for TIPS may not be as active as the secondary market
for Treasury  fixed-principal  notes and bonds. In addition,  TIPS may not be as
widely traded or as well understood as Treasury fixed-principal  securities, nor
is it known at this time exactly how the market for TIPS will develop or react.
     If the number of TIPS  market  participants  is  limited,  it may result in
larger spreads between bid and asked prices for inflation-protection  securities
than the  bid-asked  spreads for  fixed-principal  notes and bonds with  similar
terms to  maturity.  Such  larger  bid-ask  spreads  normally  result  in higher
transactions  costs  and/or  lower  returns.  If the  market  does  not  develop
sufficient   liquidity,   large  buyers  or  sellers  of  these  securities  may
disproportionately negatively impact the value of the securities and, hence, the
Fund's asset value.

     The Manager currently  believes that the market for TIPS will be sufficient
to permit  the Fund to pursue  its  investment  objective.  However,  should the
market for TIPS prove less active than  anticipated by the Manager,  the Manager
is authorized to treat such an environment as an abnormal market condition. This
means that the Manager may purchase other types of Treasury

American Century * Benham Group of Funds        Information Regarding the Fund 7


securities  in excess of 35% of the Fund's total  assets.  During such a period,
the Fund will not be fully pursuing its investment objective.

Share price volatility
     TIPS are designed to offer a return linked to inflation, thereby protecting
future  purchasing  power of the  money  invested  in them.  TIPS  provide  this
"protected" return only if held to maturity,  however. In addition, TIPS may not
trade at par value.  "Real" interest rates (the market rate of interest less the
anticipated  rate of  inflation)  change over time, as a result of many factors,
such as what investors are demanding as a true value for money.  When real rates
do change, TIPS prices will be more sensitive to these changes than conventional
bonds,  since these securities were sold originally based upon a "real" interest
rate that is no longer prevailing.  Should market expectations for real interest
rates  rise,  the  price of TIPS and the  share  price  of the Fund  will  fall.
Investors  in the Fund  should be  prepared  to accept not only this share price
volatility but also the possible adverse tax consequences it may cause.

Treasury Securities
     Under certain  circumstances the Fund will invest in fixed principal amount
U.S. Treasury bills, notes, zero-coupon bonds, and other bonds. These securities
are  direct  obligations  of the U.S.  Treasury.  Treasury  bills  have  initial
maturities  of one year or less,  Treasury  notes  from  two to ten  years,  and
Treasury  bonds more than 10 years.  These  securities  are issued  with a fixed
interest coupon rate and a fixed final value at maturity. Although U.S. Treasury
securities carry little principal risk if held to maturity,  the prices of these
securities  (like all debt  securities)  change between issuance and maturity in
response to fluctuating market interest rates.

Zero Coupon ("Stripped") Inflation-Protection Securities
     The  Fund  may  invest  in zero  coupon  ("stripped")  TIPS if they  become
available.  Further  information about such securities is currently contained in
the Statement of Additional Information.

Repurchase Agreements
     The Fund may invest in repurchase agreements when such transactions present
an attractive  short-term return on cash that is not otherwise  committed to the
purchase of securities pursuant to the investment policies of the Fund.
     A  repurchase  agreement  occurs  when,  at the time the Fund  purchases an
interest-bearing  obligation,  the seller (a bank or a broker-dealer  registered
under  the  Securities  Exchange  Act of  1934)  agrees  to  repurchase  it on a
specified  date in the future at an  agreed-upon  price.  The  repurchase  price
reflects  an  agreed-upon  interest  rate  during the time the  Fund's  money is
invested in the security.
     Since  the  security  purchased  constitutes  security  for the  repurchase
obligation,  a repurchase  agreement can be considered a loan  collateralized by
the security purchased.  The Fund's risk is the ability of the seller to pay the
agreed-upon repurchase price on the repurchase date. If the seller defaults, the
Fund may incur costs in  disposing  of the  collateral,  which would  reduce the
amount realized  thereon.  If the seller seeks relief under the bankruptcy laws,
the  disposition of the collateral may be delayed or limited.  To the extent the
value of the security decreases, the Fund could experience a loss.
     The Fund may invest in repurchase  agreements  with respect to any security
in which it is authorized to invest.

OTHER INVESTMENT PRACTICES, THEIR CHARACTERISTICS AND RISKS
     For additional  information regarding the investment practices of the Fund,
see the Statement of Additional Information.

Portfolio Turnover
     Investment  decisions  to  purchase  and sell  securities  are based on the
anticipated  contribution  of the security in question to the Fund's  objective.
The rate of portfolio  turnover is irrelevant when Management  believes a change
is in order to achieve this objective  and,  accordingly,  the annual  portfolio
turnover rate cannot be accurately  anticipated.  The portfolio  turnover of the
Fund may be higher than other mutual funds with similar investment objectives. A
high turnover rate involves  correspondingly  higher  transaction costs that are
borne  directly by the Fund. It may also affect the character of capital  gains,
if any, realized and distributed by the Fund since short-term  capital gains are
taxable as ordinary income.

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

Cash Management
     For cash management purposes,  the Fund may invest up to an aggregate total
of 5% of its total  assets in any money  market  fund  advised  by the  Manager,
provided that the investment is consistent with the Fund's  investment  policies
and restrictions.

Other Techniques
     The Manager may buy other types of  securities  or employ  other  portfolio
management  techniques on behalf of the Fund. When SEC guidelines  require it to
do so, the Fund will set aside cash or appropriate liquid assets in a segregated
account to cover the Fund's obligations.

PERFORMANCE ADVERTISING
     From  time  to  time,  the  Fund  may  advertise   performance  data.  Fund
performance  may be shown by presenting  one or more  performance  measurements,
including  cumulative  total  return or  average  annual  total  return,  yield,
effective yield and tax-equivalent yield.
     Cumulative  total  return data is computed by  considering  all elements of
return,  including  reinvestment  of dividends and capital gains  distributions,
over a stated  period of time.  Average  annual  total return is  determined  by
computing  the annual  compound  return over a stated  period of time that would
have  produced a fund's  cumulative  total  return  over the same  period if the
Fund's performance had remained constant throughout.

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

American Century * Benham Group of Funds        Information Regarding the Fund 9


income earned by the investment is assumed to be reinvested. The effective yield
will be slightly higher than the yield because of the compounding  effect on the
assumed reinvestment.
     Yields are calculated according to accounting methods that are standardized
in accordance with SEC rules. The SEC yield should be regarded as an estimate of
the Fund's rate of  investment  income,  and it may not equal the Fund's  actual
income  distribution  rate, the income paid to a shareholder's  account,  or the
income reported in the Fund's financial statements.
     A tax-equivalent  yield demonstrates the taxable yield necessary to produce
after-tax  yield  equivalent  to that of a mutual  fund which  invests in exempt
obligations.  The Fund may quote  tax-equivalent  yield,  which show the taxable
yield an investor  would have to earn before taxes to equal the Fund's  tax-free
yield. As a prospective  investor in the Fund, you should determine whether your
tax-equivalent  yield is likely to be higher with a taxable or with a tax-exempt
fund. To determine this, you may use the formulas depicted below.
     You can  calculate  your  tax-equivalent  yield for the Fund  (taking  into
account only federal income taxes and not any applicable  state taxes) using the
following equation:

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

     The Fund may also include in advertisements data comparing performance with
the performance of non-related  investment media,  published  editorial comments
and performance  rankings compiled by independent  organizations (such as Lipper
Analytical  Services or  Donoghue's  Money Fund  Report) and  publications  that
monitor the performance of mutual funds.  Performance  information may be quoted
numerically  or may be presented  in a table,  graph or other  illustration.  In
addition,  a fund's  performance may be compared to well-known indices of market
performance  including the  Donoghue's  Money Fund Average and Bank Rate Monitor
National  Index  of 2 1/2  -year CD  rates.  A  fund's  performance  may also be
compared,  on a relative  basis,  to the other  funds in our fund  family.  This
relative  comparison,  which  may be based  upon  historical  or  expected  fund
performance,  volatility  or  other  fund  characteristics,   may  be  presented
numerically,  graphically  or in  text.  The  performance  of a fund may also be
combined or blended  with other funds in our fund family,  and that  combined or
blended  performance  may be  compared to the same  indices to which  individual
funds may be compared.
     All performance  information advertised by the Fund is historical in nature
and is not intended to represent or guarantee future results.  The value of Fund
shares when redeemed may be more or less than their original cost.

made at the next net asset value determined after a complete  redemption request
is received.
     Please  note that a request to redeem  shares in an IRA or 403(b) plan must
be  accompanied  by an  executed  IRS Form W4-P and a reason for  withdrawal  as
specified by the IRS.

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

shares  each  month to provide  you with  redemption  proceeds  in an amount you
choose  (minimum $50). To set up a Check-A-Month  plan,  please call and request
our Check-A-Month brochure.

Other Automatic Redemptions
     If you have at least a $10,000  balance in your  account,  you may elect to

or to your account at a bank or other financial institution. To set up automatic
redemptions, call one of our Investor Services Representatives.

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

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

By Wire and ACH
     You may authorize us to transmit  redemption proceeds by wire or ACH. These
services will be effective 15 days after we receive the authorization.
     Your bank will usually receive wired funds within 48 hours of transmission.
Funds  transferred  by ACH may be received up to seven days after  transmission.
Wired funds are subject

14 How to Invest with American Century Investments                    Prospectus


to a $10 fee to cover  bank wire  charges,  which is  deducted  from  redemption
proceeds.  Once the funds are  transmitted,  the time of receipt  and the funds'
availability are not under our control.

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

SIGNATURE GUARANTEE
     To protect  your  accounts  from fraud,  some  transactions  will require a
signature guarantee.  Which transactions will require a signature guarantee will
depend on which  service  options  you elect  when you open  your  account.  For
example, if you choose "In Writing Only," a signature guarantee will be required
when:
     - redeeming more than $25,000; or
     - establishing  or increasing a Check-A-Month  or automatic  transfer on an
       existing account.

     You may obtain a signature  guarantee from a bank or trust company,  credit
union,  broker-dealer,  securities  exchange or association,  clearing agency or
savings association, as defined by federal law.
     For a more in-depth  explanation of our signature  guarantee  policy, or if
you live  outside  the  United  States  and  would  like to know how to obtain a
signature guarantee, please consult our Investor Services Guide.
     We reserve the right to require a signature  guarantee on any  transaction,
or to change this policy at any time.

or a price at which to sell shares of a variable-priced  fund by exchange to one
of our money market funds.  The  designated  purchase  price must be equal to or
lower, or the designated sale price equal to or higher, than the variable-priced
fund's net asset value at the time the order is placed,  If the designated price
is  met  within  90  calendar   days,  we  will  execute  your  exchange   order
automatically at that price (or better). Open orders not executed within 90 days
will be canceled.
     If the fund you have selected deducts a distribution  from its share price,
your order  price will be  adjusted  accordingly  so the  distribution  does not
inadvertently  trigger an open order transaction on your behalf. If you close or
re-register  the  account  from which the shares are to be  redeemed,  your open
order will be canceled.
     Because  of  their  time-sensitive  nature,  open  order  transactions  are
accepted  only by  telephone  or in person.  These  transactions  are subject to
exchange limitations described in each fund's prospectus, except that orders and
cancellations  received  before 2 p.m.  Central time are effective the same day,
and orders or cancellations received after 2 p.m. Central time are effective the
next business day.

IMPORTANT POLICIES REGARDING YOUR INVESTMENTS
     Every  account is subject to policies  that could  affect your  investment.
Please refer to the Investor  Services Guide for further  information  about the
policies discussed below, as well as further detail about the services we offer.
     (1) We reserve the right for any reason to suspend  the  offering of shares
         for a  period  of  time,  or to  reject  any  specific  purchase  order
         (including  purchases  by  exchange).  Additionally,  purchases  may be
         refused  if, in the  opinion  of the  Manager,  they are of a size that
         would disrupt the management of the Fund.
     (2) We  reserve  the  right  to  make  changes  to  any  stated  investment
         requirements,  including those that relate to purchases,  transfers and
         redemptions.  In addition,  we may also alter,  add to or terminate any
         investor   services  and   privileges.   Any  changes  may  affect  all
         shareholders or only certain series or classes of shareholders.
     (3) Shares  being  acquired  must be  qualified  for sale in your state of
         residence.
     (4) Transactions  requesting  a  specific  price and date,  other than open
         orders, will be refused.  Once you have mailed or otherwise transmitted
         your  transaction  instructions  to us,  they  may not be  modified  or
         canceled.

     (5) If a transaction request is made by a corporation,  partnership, trust,
         fiduciary,  agent  or  unincorporated   association,  we  will  require
         evidence  satisfactory to us of the authority of the individual  making
         the request.
     (6) We have established  procedures  designed to assure the authenticity of
         instructions received by telephone. These procedures include requesting
         personal  identification  from callers,  recording telephone calls, and
         providing  written  confirmations  of  telephone  transactions.   These
         procedures are designed to protect  shareholders  from  unauthorized or
         fraudulent  instructions.  If we do not employ reasonable procedures to
         confirm  the  genuineness  of  instructions,  then we may be liable for
         losses due to unauthorized or fraudulent instructions. The company, its
         transfer agent and investment  adviser will not be responsible  for any
         loss due to instructions they reasonably believe are genuine.
     (7) All  signatures   should  be  exactly  as  the  name  appears  in  the
         registration.  If the owner's name appears in the registration as Mary
         Elizabeth Jones, she should sign that way and not as Mary E. Jones.
     (8) Unusual  stock  market  conditions  have  in the  past  resulted  in an
         increase  in  the  number  of  shareholder   telephone  calls.  If  you
         experience  difficulty in reaching us during such periods, you may send
         your transaction instructions by mail, express mail or courier service,
         or you may visit  one of our  Investors  Centers.  You may also use our
         Automated Information Line if you have requested and received an access
         code and are not attempting to redeem shares.
     (9) If  you  fail  to  provide  us  with  the  correct  certified  taxpayer
         identification  number, we may reduce any redemption proceeds by $50 to
         cover the  penalty the IRS will impose on us for failure to report your
         correct taxpayer identification number on information reports.

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

REPORTS TO SHAREHOLDERS
     At the end of  each  calendar  quarter,  we will  send  you a  consolidated
statement that summarizes all of your American Century  holdings,  as well as an
individual  statement  for  each  fund you own that  reflects  all  year-to-date
activity in your account.  You may request a statement of your account  activity
at any time.
     With the exception of most  automatic  transactions,  each time you invest,
redeem,  transfer or exchange  shares,  we will send you a  confirmation  of the
transactions. See the Investor Services Guide for more detail.
     Carefully  review all the  information  relating  to  transactions  on your
statements  and  confirmations  to ensure that your  instructions  were acted on
properly.  Please notify us immediately in writing if there is an error.  If you
fail to provide  notification  of an error  with  reasonable  promptness,  i.e.,
within 30 days of  non-automatic  transactions  or within 30 days of the date of
your consolidated quarterly statement, in the case of automatic transactions, we
will deem you to have ratified the transaction.

     No later than January 31st of each year,  we will send you reports that you
may use in completing  your U.S.  income tax return.  See the Investor  Services
Guide  for  more  information.  Each  year,  we will  send you an  annual  and a
semiannual report relating to your fund, each of which is incorporated herein by
reference. The annual report includes audited financial statements and a list of
portfolio  securities as of the fiscal year end. The semiannual  report includes
unaudited  financial  statements for the first six months of the fiscal year, as
well as a list of portfolio  securities at the end of the period.  You also will
receive an updated prospectus at

you understand your fund.

EMPLOYER-SPONSORED RETIREMENT PLANS AND INSTITUTIONAL ACCOUNTS
     Information   contained  in  our  Investor   Services   Guide  pertains  to
shareholders  who invest  directly with American  Century rather than through an
employer-sponsored retirement plan or through a financial intermediary.
     If  you  own  or  are   considering   purchasing  Fund  shares  through  an
employer-sponsored retirement plan, your ability to purchase shares of the Fund,
exchange them for shares of other American  Century funds,  and redeem them will
depend on the terms of your plan.
     If you  own or are  considering  purchasing  Fund  shares  through  a bank,
broker-dealer,  insurance company or other financial intermediary,  your ability
to purchase,  exchange and redeem shares will depend on your agreement with, and
the policies of, such financial intermediary.
     You may reach one of our Institutional Investor Service  Representatives by
calling  1-800-345-3533 to request information about our funds and services,  to

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

SHARE PRICE

When Share Price Is Determined
     The price of your shares is also referred to as their net asset value.  Net
asset value is determined  by  calculating  the total value of a Fund's  assets,
deducting  total  liabilities  and  dividing  the result by the number of shares
outstanding.  Net asset value is determined  at the close of regular  trading on
each day that the New York Stock Exchange (the "Exchange") is open.
     Investments  and  requests  to redeem or exchange  shares will  receive the
share price next determined  after receipt by us of the investment or redemption
or exchange request. For example, investments and requests to redeem or exchange
shares  received by us or our authorized  agents before the close of business on
the Exchange,  usually 3 p.m.  Central time,  are effective on, and will receive
the  price  determined,  that day as of the close of the  Exchange.  Investment,
redemption  and exchange  requests  received  thereafter  are  effective on, and
receive the price  determined  as of, the close of the  Exchange on the next day
the Exchange is open.
     Investments are considered received only when your check or wired funds are
received  by us.  Wired  funds  are  considered  received  on the day  they  are
deposited in our bank account if they are deposited before the close of business
on the Exchange.
     Investments by telephone pursuant to your prior authorization to us to draw
on your bank account are considered received at the time of your telephone call.
Investment and  transaction  instructions  received by us on any business day by
mail prior to the close of  business on the  Exchange  will  receive  that day's
price.  Investments and  instructions  received after that time will receive the
price determined on the next business day.
     If you invest in Fund shares through an employer-sponsored  retirement plan
or  other  financial  intermediary,  it  is  the  responsibility  of  your  plan
recordkeeper or financial  intermediary to transmit your purchase,  exchange and
redemption requests to the Funds' transfer agent prior to the applicable cut-off
time for receiving  orders and to make payment for any purchase  transactions in
accordance with the Fund's  procedures or any contractual  arrangement  with the
Fund or the Fund's distributor in order for you to receive that day's price.

How Share Price Is Determined

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

     Portfolio  securities  of the Fund,  except as otherwise  noted,  listed or
traded on a domestic  securities  exchange  are valued at the last sale price on
that  exchange.  Portfolio  securities  primarily  traded on foreign  securities
exchanges  are  generally  valued  at  the  preceding  closing  values  of  such
securities on the exchange where primarily traded. If no sale is reported, or if
local convention or regulation so provides, the mean of the latest bid and asked
prices is used.  Depending on local convention or regulation,  securities traded
over-the-counter  are priced at the mean of the latest bid and asked prices,  or
at the last sale  price.  When  market  quotations  are not  readily  available,
securities and other assets are valued at fair value as determined in accordance
with procedures adopted by the board of directors/trustees.
     Debt  securities not traded on a principal  securities  exchange are valued
through  valuations  obtained from a commercial  pricing  service or at the most
recent  mean of the bid and asked  prices  provided  by  investment  dealers  in
accordance with procedures established by the board of trustees.

Where To Find Information About Share Price
     The net asset value of the Fund is published in leading  newspapers  daily.

DISTRIBUTIONS
     At the close of each day including  Saturdays,  Sundays and  holidays,  net
income of the Fund, included amounts  attributable to increases in the principal
amount of TIPS, is determined and declared as a distribution.  The  distribution
will be paid monthly.
     You will  begin to  participate  in the  distributions  the day after  your
purchase is  effective.  See "When Share Price is  Determined,"  page __. If you
redeem  shares,  you will receive the  distribution  declared for the day of the
redemption.  If all shares are redeemed, the distribution on the redeemed shares
will be included with your redemption proceeds.
     Distributions  from net  realized  capital  gains,  if any,  generally  are
declared  and paid once a year,  but the Fund may make  distributions  on a more
frequent  basis to comply with the  distribution  requirements  of the  Internal
Revenue Code and its Regulations,  in all events in a manner consistent with the
provisions of the 1940 Act.
     Participants  in  employer-sponsored   retirement  or  savings  plans  must
reinvest all distributions. For shareholders investing through taxable accounts,
distributions  will be  reinvested  unless  you elect to  receive  them in cash.
Distributions of less than $10 generally will be reinvested.  Distributions made
shortly  after a  purchase  by check  or ACH may be held up to 15 days.  You may
elect to have distributions on shares held in Individual Retirement Accounts and
403(b)  plans paid in cash only if you are 59 1/2 years old or  permanently  and
totally  disabled.  Distribution  checks  normally are mailed  within seven days
after the record date.  Please  consult our Investor  Services Guide for further
information regarding your distribution options.

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

Tax-Deferred Accounts
     If the Fund's shares are purchased through tax-deferred accounts, such as a
qualified  employer-sponsored  retirement  or savings  plan,  income and capital
gains  distributions  paid by the Fund will  generally not be subject to current
taxation,  but will  accumulate in your account under the plan on a tax-deferred
basis.  Employer-sponsored  retirement and savings plans are governed by complex
tax rules.  If you elect to participate in your  employer's  plan,  consult your
plan administrator,  your plan's summary plan description, or a professional tax
advisor   regarding  the  tax   consequences  of   participation  in  the  plan,
contributions to, and withdrawals or distributions from the plan.

Taxable Accounts

     If Fund shares are purchased through taxable accounts, distributions of net
investment  income  and net  short-term  capital  gains  are  taxable  to you as
ordinary income, except as described below. The dividends from net income of the
Fund does not qualify for the 70% dividends-received  deduction for corporations
since they are derived  from  interest  income.  Dividends  representing  income
derived from tax-exempt bonds generally retain the bonds' tax-

20 Additional Information You Should Know                             Prospectus


exempt  character in a  shareholder's  hands.  Distributions  from net long-term
capital gains are taxable as long-term capital gains regardless of the length of
time you have held the shares on which such distributions are paid. However, you
should note that any loss  realized  upon the sale or  redemption of shares held
for six months or less will be treated as a long-term capital loss to the extent
of any  distribution  of  long-term  capital  gain to you with  respect  to such
shares.
     The TIPS  purchased  by the Fund  accrue  additional  interest  for federal
income tax purposes in addition to the current  interest paid.  This  additional
interest is commonly referred to as "imputed  income".  The Fund must distribute
this imputed income to  shareholders  as ordinary  income  dividends,  which are
subject to federal  taxes but generally  exempt from state taxes.  In periods of
high  inflation,  it is possible that the imputed income earned by the Fund will
exceed current interest earned.
     Distributions  of capital  gains are taxable to you  regardless  of whether
they are taken in cash or reinvested,  even if the value of your shares is below
your cost. If you purchase  shares shortly  before a capital gain  distribution,
you must pay income  taxes on the  distribution,  even  though the value of your
investment  (plus cash received,  if any) will not have increased.  In addition,
the share price at the time you purchase shares may include  unrealized gains in
the securities held in the investment  portfolio of the Fund. If these portfolio
securities are subsequently  sold and the gains are realized,  they will, to the
extent not offset by capital losses, be paid to you as a distribution of capital
gains and will be taxable to you as short-term or long-term capital gains.
     In January of the year following the  distribution,  if you own shares in a
taxable account, we or your financial intermediary will send you a Form 1099-DIV
notifying  you of the  status  of your  distributions  for  federal  income  tax
purposes.  Distributions  may also be subject to state and local taxes,  even if
all or a substantial part of such distribution are derived from interest on U.S.
government  obligations  which,  if you received them directly,  would be exempt
from state income tax. However, most but not all states allow this tax exemption
to pass  through  to Fund  shareholders  when a Fund pays  distributions  to its
shareholders.  You should  consult your tax adviser about the tax status of such
distributions in your own state.
     If you have not complied with certain  provisions  of the Internal  Revenue
Code and its  Regulations,  we are required by federal law to withhold and remit
to the IRS 31% of  reportable  payments  (which may include  dividends,  capital
gains  distributions and redemptions).  Those regulations require you to certify
that the social  security  number or tax  identification  number you  provide is
correct  and  that  you  are  not  subject  to  31%   withholding  for  previous
underreporting   to  the  IRS.  You  will  be  asked  to  make  the  appropriate
certification on your application. Payments reported by us that omit your social
security  number or tax  identification  number will  subject us to a penalty of
$50,  which  will be charged  against  your  account if you fail to provide  the
certification by the time the report is filed, and is not refundable.
     Redemption of shares of the Fund (including redemptions made in an exchange
transaction)  will be a taxable  transaction for federal income tax purposes and
shareholders  will generally  recognize a gain or loss in an amount equal to the
difference  between  the basis of the shares and the amount  received.  Assuming
that  shareholders hold such shares as a capital asset, the gain or loss will be
a capital gain or loss and will generally be long term if shareholders have held
such  shares for a period of more than one year.  If a loss is  realized  on the
redemption of Fund shares,  the reinvestment in additional Fund shares within 30
days before or after the  redemption  may be subject to the "wash sale" rules of
the Internal  Revenue Code,  resulting in a postponement  of the  recognition of
such loss for federal income tax purposes.

MANAGEMENT

Investment Management
     The Fund is a series of the American  Century  Government  Income Trust,  a
Massachusetts  business  trust formerly  known as the Benham  Government  Income
Trust (the "Trust"),  and is officially designated as "American Century - Benham
Treasury  Inflation   Protection   Securities  Fund".  Under  the  laws  of  the
Commonwealth of Massachusetts, the board of trustees is responsible for managing
the business and affairs of the Trust.
     Acting pursuant to an investment  advisory  agreement entered into with the
Trust,  Benham  Management  Corporation (the "Manager") serves as the investment
adviser of the Fund. Its principal  place of business is 1665  Charleston  Road,
Mountain  View,  California  94043.  The Manager has been  providing  investment
advisory services to investment companies and other clients since 1971.
     The Manager supervises and manages the investment portfolio of the Fund and
directs the purchase and sale of its investment securities. The Manager utilizes
a team of portfolio  managers,  assistant portfolio managers and analysts acting
together to manage the assets of the Fund.  The team meets  regularly  to review
portfolio  holdings and to discuss purchase and sale activity.  The team adjusts
holdings  in the  Fund's  portfolios  and  the  Fund's  asset  mix  as it  deems
appropriate in pursuit of the Fund's investment objective.  Individual portfolio
manager members of the team may also adjusts  portfolio  holdings of the Fund as
necessary between team meetings.
     In June 1995,  American Century  Companies,  Inc. ("ACC"),  acquired Benham
Management  International,  Inc., the then-parent company of the Manager. ACC is
the parent company of American Century  Investment  Management,  Inc.  ("ACIM"),
which  provides  investment  advisory  services  to many  funds in the  American
Century family of funds. In the  acquisition,  the Manager became a wholly owned
subsidiary of ACC. Certain employees of the Manager will be providing investment
management  services to funds  managed by ACIM,  while  certain  ACIM  employees
provide investment management services to fund managed by the Manager.
     David  Schroeder  joined  the  Manager  in  1990  and  has  been  primarily
responsible for the day-to-day operations of the Fund since its inception and is
in charge of the team  managing  the Fund.  Mr.  Schroeder  also has managed the
American Century-Benham Intermediate-Term Treasury Fund since January, 1992, the
American  Century-Benham  Long-Term  Treasury Fund since  September,  1992,  and
American  Century Target  Maturities  Trust since July,  1990. Mr. Schroeder has
co-managed the American Century-Benham GNMA Fund since January, 1996.
     The  activities  of the  Manager  are  subject  only  to  direction  of the
trustees.  The Manager  pays all of the  expenses of the Fund except  brokerage,
taxes,  interest and fees and expenses of the disinterested  Trustees (including
counsel fees) and extraordinary expenses.
     For the  services  provided to the Fund by the  Manager,  the Fund pays the
Manager a monthly  investment  advisory  fee  equal to an  amount  derived  from
applying  the Trust's  average  daily net assets to an  investment  advisory fee
schedule.
     The investment  advisory fee rate ranges from .45% to .35% of average daily
net assets, dropping as the Fund's total assets increase.

Code Of Ethics
     The Fund and the Manager  have  adopted a Code of Ethics,  which  restricts
personal  investing  practices by  employees of the Manager and its  affiliates.
Among other  provisions,  the Code of Ethics requires that employees with access
to information about the purchase or sale of securities in the Fund's portfolios
obtain  preclearance before executing personal trades. With respect to portfolio
managers  and  other  investment   personnel,   the  Code  of  Ethics  prohibits
acquisition of

22 Additional Information You Should Know                             Prospectus


securities in an initial public  offering,  as well as profits  derived from the
purchase and sale of the same security within 60 calendar days. These provisions
are designed to ensure that the interests of the Fund  shareholders  come before
the interests of the people who manage the Fund.

Transfer And Administrative Services
     American  Century  Services  Corporation,  4500 Main  Street,  Kansas City,
Missouri,  64111,  (the  "transfer  agent")  acts  as  transfer,  administrative
services and dividend  paying agent for the Fund.  The transfer  agent  provides
facilities, equipment and personnel to the Fund and is paid for such services by
the Fund. For transfer and administrative  services,  the Manager, not the Fund,
pays the transfer agent a monthly fee.
     The Fund charges no sales  commissions,  or "loads," of any kind.  However,
investors  who do not choose to purchase or sell Fund shares  directly  from the
transfer   agent  may   purchase   or  sell  Fund  shares   through   registered
broker-dealers and other qualified service  providers,  who may charge investors
fees for their services.  These  broker-dealers and service providers  generally
provide  shareholder,  administrative  and/or  accounting  services  which would
otherwise be provided by the transfer agent. To accommodate these investors, the
Manager and its affiliates have entered into agreements with some broker-dealers
and service providers to provide these services. Fees for such services are paid
by the Manager at the rates  normally  paid to the transfer  agent,  which would
otherwise provide the services.  Any distribution expenses associated with these
arrangements are also borne by the Manager.
     Although  there is no sales  charge  levied  by the Fund,  transactions  in
shares of the Fund may be executed by brokers or investment  advisers who charge
a transaction-based  fee or other fee for their services.  Such charges may vary
among  broker-dealers and financial advisors,  but in all cases will be retained
by the  broker-dealer  or financial  advisor and not remitted to the Fund or the
Manager.  You  should be aware of the fact that these  transactions  may be made
directly with American Century without incurring such fees.
     From time to time,  special  services  may be offered to  shareholders  who
maintain  higher  share  balances  in our family of funds.  These  services  may
include the waiver of minimum investment requirements, expedited confirmation of
shareholder  transactions,  newsletters and a team of personal  representatives.
Any expenses  associated with these special services will be paid by the Manager
or its affiliates.
     The Manager and the transfer  agent are both wholly owned by ACC.  James E.
Stowers Jr.,  Chairman of the board of directors of ACC,  controls ACC by virtue
of his ownership of a majority of its common stock.

Distribution Of Fund Shares
     The Fund's shares are distributed by American Century Investment  Services,
Inc. (the  "Distributor"),  a registered  broker-dealer  and an affiliate of the
Manager. The Manager 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.

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

FURTHER INFORMATION ABOUT THE FUND
     The Trust was organized as a  Massachusetts  business trust in May 1, 1984.
The  Trust is a  diversified,  open-end  management  investment  company.  Their
business  and affairs are managed by its  officers  under the  direction  of the
board of trustees.
     The  principal  office of the Fund is  American  Century  Tower,  4500 Main
Street, P.O. Box 419200, Kansas City, Missouri 64141-6200. All inquiries made by
mail should be directed  to the  address and phone  numbers on the cover,  or by
phone to 1-800-345-2021. (international calls: 816-531-5575.)
     The Fund is an individual series of the Trust which also issues shares with
no par value.  The assets belonging to each series of shares are held separately
by the custodian and in effect each series is a separate fund.
     Each share, irrespective of series, is entitled to one vote for each dollar
of net asset value  applicable to such share on all  questions,  except,  in the
case of the Trust, those matters which must be voted on separately by the series
of shares affected.  Matters affecting only one Fund are voted upon only by that
Fund.
     Shares of the Trust have noncumulative  voting rights, which means that the
holders of more than 50% of the shares  voting for the  election of trustees can
elect all of the trustees if they choose to do so, and in such event the holders
of the  remaining  less-than  50% of the  shares  will not be able to elect  any

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

   
Repurchase Agreements (Variable Price Funds)
The Funds may engage in repurchase  agreements  collateralized  by U.S. Treasury
bills,  notes, and bonds, or by  mortgage-backed  GNMA  certificates,  which are
guaranteed by the Government  National  Mortgage  Association  and backed by the
full faith and credit of the U.S. government.
    

Repos  may  involve  risks  not  associated  with  direct  investments  in  U.S.
government  debt  securities.  If the seller  fails to complete the terms of the
agreement,  the Fund may experience delays in recovering its cash or incur costs
in the disposal of  securities it has purchased  under the  agreement.  The Fund
could also suffer a loss if the  securities  decline in value before they can be
sold in the open market.

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

   
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 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 trustees;

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

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

(5)  Investing  no more  than  10% of the  Fund's  total  assets  in  repurchase
     agreements  of more than seven  days'  duration  (although  the  underlying
     securities usually will have longer maturities);

(6)  Taking delivery of securities subject to repurchase  agreements and holding
     them in a segregated account at the Fund's custodian bank.

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

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


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

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

                                       2

American Century Government Income Trust
Statement of Additional Information
- --------------------------------------------------------------------------------

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, U.S.  government  securities,  or other high-quality  liquid
debt  securities in an amount  sufficient to meet the purchase  price.  When the
time comes to pay for such  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 when-issued  securities  themselves
(which  may  have a  market  value  greater  or less  than  the  Fund's  payment
obligation).  Selling  securities  to meet  when-issued  or  forward  commitment
obligations may generate taxable capital gains or losses.


   
Roll Transactions
A Fund may sell a security  and at the same time make a  commitment  to purchase
the  same or a  comparable  security  at a  future  date  and  specified  price.
Conversely,  a  Fund  may  purchase  a  security  and at the  same  time  make a
commitment  to sell  the same or a  comparable  security  at a  future  date and
specified price. These types of transactions are executed simultaneously in what
are known as "dollar-rolls",  "cash-and-carry",  or financing transactions.  For
example, a broker-dealer may seek to purchase a particular  security that a Fund
owns. The Fund will sell that security to the broker-dealer  and  simultaneously
enter into a forward commitment  agreement to buy it back at a future date. This
type of  transaction  generates  income for the Fund if the dealer is willing to
execute  the  transaction  at a  favorable  price in order to acquire a specific
security.  As  an  operating  policy,  the  Manager  limits  forward  commitment
transactions  (including roll  transactions) to 35% of a Fund's total assets and
will  not  enter  into  when-issued  or  forward  commitment  transactions  with
settlement dates that exceed 120 days.
    

In engaging in roll  transactions,  the Fund will maintain  until the settlement
date a segregated account consisting of cash, cash equivalents,  or high-quality
liquid  securities  in an  amount  sufficient  to meet the  purchase  price,  as
described above.


Interest Rate Resets on Floating-Rate U.S. Government Agency Securities
Interest  rate  resets  on  floating-rate  U.S.   government  agency  securities
generally  occur at  intervals  of one year or less in  response to changes in a
predetermined  interest  rate index.  There are two main  categories of indexes,
those based on U.S.  Treasury  securities  and those  derived  from a calculated
measure,  such as a cost of funds  index.  Commonly  used  indexes  include  the
three-month,  six-month,  and one-year Treasury bill rate; the two-year Treasury
note yield;  the  Eleventh  District  Federal Home Loan Bank Cost of Funds Index
(EDCOFI);  and the London  Interbank  Offered Rate (LIBOR).  Fluctuations in the
prices  of  floating-rate  U.S.   government  agency  securities  are  typically
attributed  to  differences  between the coupon  rates on these  securities  and
prevailing market interest rates between interest rate reset dates.


   
Master Demand Notes (Government Agency only)
Government Agency may acquire  variable-rate  master demand notes issued by U.S.
government  agencies  such as the Student  Loan  Marketing  Association.  Master
demand  notes allow the Fund to lend money at varying  rates of  interest  under
direct agreements with borrowers. The Fund may adjust the amount of money loaned
under a master  demand note daily or weekly up to the full amount  specified  in
the  agreement,  and the  borrower  may prepay up to the full amount of the loan
without penalty. Master demand notes may or may not be backed by bank letters of
credit.  Although, as direct agreements between lenders and borrowers,  there is
no secondary  market for master demand notes,  these  instruments are redeemable
(immediately  repayable by the  borrower)  at par plus  accrued  interest at any
time.


Securities Lending (All Funds Except Intermediate-Term Treasury)
The Manager may seek approval from the board of trustees to engage in securities
lending on behalf of the Funds.  Such loans would be made with the  intention of
allowing  the Funds to earn  additional  income.  If a borrower  defaulted  on a
securities  loan,  the lending Fund could  experience  delays in recovering  the
securities  it loaned;  if the value of the loaned  securities  increased in the
meantime,  the Fund  could  suffer a loss.  To  minimize  the risk of default on
securities loans, the Manager adheres to the following guidelines  prescribed by
the board of trustees:
    

(1)  Type and Amount of  Collateral.  At the time a loan is made,  the Fund must
     receive,  from or on behalf of a  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 a 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.

(2)  Additions to Collateral. Collateral must be marked to market daily, and the
     borrower must agree to add  collateral to the 

                                       3

American Century Government Income Trust
Statement of Additional Information
- --------------------------------------------------------------------------------

     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 ability to terminate a 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.  The normal settlement period
     for U.S. government securities is typically two trading days.

(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 Fund Assets on Loan. A Fund's loans may not
     exceed 33 1/3 % of its total assets.

   
(6)  Credit Analysis.  As part of the regular monitoring procedures set forth by
     the board of  trustees  that the  Manager  follows  to  evaluate  banks and
     broker-dealers in connection with, for example,  repurchase  agreements and
     municipal  securities  credit issues,  the Manager will analyze and monitor
     the   creditworthiness  of  all  borrowers  with  which  portfolio  lending
     arrangements are contemplated or entered into.
    


Mortgage-Backed Securities (ARM Fund and GNMA Fund)
Background.  A mortgage-backed  security  represents an ownership  interest in a
pool of mortgage loans. The loans are made by financial  institutions to finance
home and other real estate purchases. As the loans are repaid, investors receive
payments of both interest and principal.

Like  fixed-income  securities  such as  U.S.  Treasury  bonds,  mortgage-backed
securities pay a stated rate of interest over the life of the security. However,
unlike  a bond,  which  returns  principal  to the  investor  in one lump sum at
maturity,  mortgage-backed  securities  return  principal  to  the  investor  in
increments over the life of the security.

Because  the timing and speed of  principal  repayments  vary,  the cash flow on
mortgage  securities  is  irregular.  If  mortgage  holders  sell  their  homes,
refinance their loans,  prepay their  mortgages,  or default on their loans, the
principal is distributed pro rata to investors.

As with  other  fixed-income  securities,  the  prices  of  mortgage  securities
fluctuate in response to changing  interest rates; when interest rates fall, the
prices of mortgage securities rise, and vice versa. Changing interest rates have
additional  significance  for  mortgage-backed  securities  investors,  however,
because they influence  prepayment  rates (the rates at which  mortgage  holders
prepay  their  mortgages),  which in turn  affect the yields on  mortgage-backed
securities.  When interest rates decline,  prepayment rates generally  increase.
Mortgage  holders take advantage of the opportunity to refinance their mortgages
at lower rates with lower monthly payments.  When interest rates rise,  mortgage
holders are less inclined to refinance their mortgages. The effect of prepayment
activity on yield depends on whether the mortgage-backed  security was purchased
at a premium or at a discount.

A Fund may get back  principal  sooner than it expected  because of  accelerated
prepayments. Under these circumstances, the Fund might have to reinvest returned
principal  at rates lower than it would have earned if principal  payments  were
made  on  schedule.  Conversely,  a  mortgage-backed  security  may  exceed  its
anticipated  life if  prepayment  rates  decelerate  unexpectedly.  Under  these
circumstances,  a Fund  might miss an  opportunity  to earn  interest  at higher
prevailing rates.

Ginnie Mae Certificates.  The Government National Mortgage  Association (GNMA or
Ginnie Mae) is a wholly owned  corporate  instrumentality  of the United  States
within the Department of Housing and Urban Development. The National Housing Act
of 1934 (Housing Act), as amended, authorizes Ginnie Mae to guarantee the timely
payment of interest and repayment of principal on  certificates  that are backed
by a pool of mortgage loans insured by the Federal Housing  Administration under
the  Housing  Act,  or by Title V of the  Housing  Act of 1949 (FHA  Loans),  or
guaranteed by the Veterans'  Administration under the Servicemen's  Readjustment
Act of 1944 (VA  Loans),  as  amended,  or by pools of other  eligible  mortgage
loans.  The  Housing  Act  provides  that the full  faith and credit of the U.S.
government  is pledged to the payment of all amounts  that may be required to be
paid under any guarantee.  Ginnie Mae has unlimited authority to borrow from the
U.S. Treasury in order to meet its obligations under this guarantee.

Ginnie Mae  certificates  represent a pro rata  interest in one or more pools of
the following types of mortgage  loans:  (a) fixed-rate  level payment  mortgage
loans; (b) fixed-rate  graduated  payment mortgage loans (GPMs);  (c) fixed-rate
growing equity mortgage loans (GEMs);  (d) fixed-rate  mortgage loans secured by
manufactured (mobile) homes (MHs); (e) mortgage loans on multifamily residential
properties  under   construction   (CLCs);   (f)  mortgage  loans  on  completed
multifamily  projects

                                       4

American Century Government Income Trust
Statement of Additional Information
- --------------------------------------------------------------------------------

(PLCs);  (g)  fixed-rate  mortgage  loans that use escrowed  funds to reduce the
borrower's  monthly  payments  during  the  early  years of the  mortgage  loans
(buydown  mortgage  loans);  and (h)  mortgage  loans that  provide  for payment
adjustments  based on  periodic  changes in interest  rates or in other  payment
terms of the mortgage loans.

Fannie Mae  Certificates.  The Federal National  Mortgage  Association  (FNMA or
Fannie Mae) is a federally chartered and privately owned corporation established
under the Federal  National  Mortgage  Association  Charter Act.  Fannie Mae was
originally  established in 1938 as a U.S.  government agency designed to provide
supplemental  liquidity  to  the  mortgage  market  and  was  reorganized  as  a
stockholder-owned  and privately managed  corporation by legislation  enacted in
1968. Fannie Mae acquires capital from investors who would not ordinarily invest
in  mortgage  loans  directly  and  thereby  expands  the total  amount of funds
available for housing.  This money is used to buy home mortgage loans from local
lenders, replenishing the supply of capital available for mortgage lending.

Fannie Mae  certificates  represent a pro rata  interest in one or more pools of
FHA Loans,  VA Loans,  or, most  commonly,  conventional  mortgage  loans (i.e.,
mortgage loans that are not insured or guaranteed by a  governmental  agency) of
the following types: (a) fixed-rate level payment mortgage loans; (b) fixed-rate
growing equity mortgage loans; (c) fixed-rate  graduated payment mortgage loans;
(d) adjustable-rate mortgage loans; and (e) fixed-rate mortgage loans secured by
multifamily projects.

Fannie  Mae  certificates  entitle  the  registered  holder to  receive  amounts
representing  a pro rata interest in scheduled  principal and interest  payments
(at the  certificate's  pass-through  rate,  which is net of any  servicing  and
guarantee fees on the underlying mortgage loans), any principal prepayments, and
a  proportionate  interest in the full  principal  amount of any  foreclosed  or
otherwise  liquidated mortgage loan. The full and timely payment of interest and
repayment of principal on each Fannie Mae  certificate  is  guaranteed by Fannie
Mae;  this  guarantee  is not  backed by the full  faith and  credit of the U.S.
government.

Freddie Mac Certificates.  The Federal Home Loan Mortgage  Corporation (FHLMC or
Freddie  Mac)  is a  corporate  instrumentality  of the  United  States  created
pursuant to the  Emergency  Home  Finance Act of 1970 (FHLMC  Act),  as amended.
Freddie  Mac  was  established  primarily  for the  purpose  of  increasing  the
availability of mortgage credit.  Its principal  activity consists of purchasing
first-lien conventional  residential mortgage loans (and participation interests
in such mortgage loans) and reselling these loans in the form of mortgage-backed
securities, primarily Freddie Mac certificates.

Freddie Mac  certificates  represent a pro rata  interest in a group of mortgage
loans (a Freddie Mac certificate  group)  purchased by Freddie Mac. The mortgage
loans underlying  Freddie Mac certificates  consist of fixed- or adjustable-rate
mortgage  loans with original terms to maturity of between ten and thirty years,
substantially  all of which are secured by  first-liens  on one- to  four-family
residential  properties or  multifamily  projects.  Each mortgage loan must meet
standards  set  forth in the FHLMC  Act.  A Freddie  Mac  certificate  group may
include whole loans, participation interests in whole loans, undivided interests
in whole loans,  and  participations  composing  another Freddie Mac certificate
group.

Freddie Mac guarantees to each  registered  holder of a Freddie Mac  certificate
the timely  payment of interest  at the rate  provided  for by the  certificate.
Freddie Mac also guarantees  ultimate collection of all principal on the related
mortgage  loans,  without  any  offset  or  deduction,  but  generally  does not
guarantee the timely repayment of principal.  Freddie Mac may remit principal at
any time after default on an underlying mortgage loan, but no later than 30 days
following (a) foreclosure  sale, (b) payment of a claim by any mortgage insurer,
or (c) the expiration of any right of redemption, whichever occurs later, and in
any event no later than one year after  demand has been made upon the  mortgager
for accelerated payment of principal.  Obligations guaranteed by Freddie Mac are
not backed by the full faith and credit of the U.S. government.

Collateralized Mortgage Obligations (CMOs). A CMO is a multiclass bond backed by
a pool of mortgage  pass-through  certificates or mortgage  loans.  CMO's may be
collateralized  by (a) Ginnie  Mae,  Fannie  Mae,  or Freddie  Mac  pass-through
certificates,  (b)  unsecuritized  mortgage loans insured by the Federal Housing
Administration  or  guaranteed  by the  Department  of  Veterans'  Affairs,  (c)
unsecuritized conventional mortgages, or (d) any combination thereof.

In  structuring  a CMO,  an issuer  distributes  cash  flow from the  underlying
collateral over a series of classes called "tranches".  Each CMO is a set of two
or more  tranches,  with average lives and cash flow  patterns  designed to meet
specific investment  objectives.  The average life expectancies of the different
tranches in a four-part deal, for example, might be two, five, seven, and twenty
years.

As payments on the underlying mortgage loans are collected,  the CMO issuer pays
the coupon rate of interest to the  bondholders in each tranche.  At the outset,
scheduled  and  unscheduled  principal  payments  go to  investors  in the first
tranches.  Investors in later tranches do not begin receiving principal payments
until the prior  tranches  are paid off.  This  basic  type of CMO is known as a
"sequential pay" or "plain vanilla" CMO.

                                       5

American Century Government Income Trust
Statement of Additional Information
- --------------------------------------------------------------------------------

Some CMOs are structured so that the prepayment or market risks are  transferred
from one tranche to another.  Prepayment  stability is improved in some tranches
if other tranches absorb more prepayment variability.

The final  tranche of a CMO often  takes the form of a Z-bond,  also known as an
"accrual bond" or "accretion bond." Holders of these securities  receive no cash
until the earlier  tranches  are paid in full.  During the period that the other
tranches are outstanding,  periodic  interest  payments are added to the initial
face amount of the Z-bond but are not paid to investors. When the prior tranches
are retired, the Z-bond receives coupon payments on its higher principal balance
plus any principal prepayments from the underlying mortgage loans. The existence
of a Z-bond tranche helps stabilize cash flow patterns in the other tranches. In
a changing interest rate environment,  however, the value of the Z-bond tends to
be more volatile.

As CMOs have evolved, some classes of CMO bonds have become more prevalent.  The
planned  amortization  class (PAC) and targeted  amortization  class (TAC),  for
example,  were designed to reduce prepayment risk by establishing a sinking-fund
structure.  PAC and TAC bonds  assure to varying  degrees  that  investors  will
receive payments over a predetermined period under various prepayment scenarios.
Although  PAC and TAC bonds are  similar,  PAC bonds are better  able to provide
stable cash flows under various  prepayment  scenarios than TAC bonds because of
the order in which these tranches are paid.

The existence of a PAC or TAC tranche can create higher levels of risk for other
tranches in the CMO because the  stability of the PAC or TAC tranche is achieved
by creating at least one other  tranche-known as a companion bond,  support,  or
non-PAC  bond--that  absorbs the  variability of principal  cash flows.  Because
companion bonds have a high degree of average life  variability,  they generally
pay a higher yield. A TAC bond can have some of the prepayment  variability of a
companion bond if there is also a PAC bond in the CMO issue.

Floating-rate  CMO tranches  (floaters)  pay a variable rate of interest that is
usually  tied  to the  London  Interbank  Offered  Rate  (LIBOR).  Institutional
investors with  short-term  liabilities,  such as commercial  banks,  often find
floating-rate  CMOs  attractive  investments.  "Super  floaters"  (which float a
certain percentage above LIBOR) and "inverse floaters" (which float inversely to
LIBOR) are variations on the floater  structure  that have highly  variable cash
flows.

Stripped   Mortgage-Backed   Securities  (ARM  Fund  only).   Stripped  mortgage
securities are created by segregating  the cash flows from  underlying  mortgage
loans or mortgage  securities to create two or more new securities,  each with a
specified  percentage  of  the  underlying   security's  principal  or  interest
payments.  Mortgage  securities may be partially  stripped so that each investor
class receives some interest and some principal.  When securities are completely
stripped,  however, all of the interest is distributed to holders of one type of
security, known as an interest-only security, or IO, and all of the principal is
distributed  to holders of another  type of security  known as a  principal-only
security,  or PO.  Strips  can be  created  in a  pass-through  structure  or as
tranches of a CMO.

The  market  values  of IOs and POs are  very  sensitive  to  interest  rate and
prepayment rate fluctuations.  POs, for example, increase (or decrease) in value
as interest rates decline (or rise). The price behavior of these securities also
depends  on  whether  the  mortgage  collateral  was  purchased  at a premium or
discount to its par value. Prepayments on discount coupon POs generally are much
lower than  prepayments on premium coupon POs. IOs may be used to hedge a Fund's
other investments  because prepayments cause the value of an IO strip to move in
the opposite direction from other mortgage-backed securities.

Adjustable-Rate Mortgage Loans (ARMs). ARMs eligible for inclusion in a mortgage
pool will  generally  provide for a fixed initial  mortgage  interest rate for a
specified  period of time,  generally for either the first three,  six,  twelve,
thirteen,  thirty-six,  or sixty scheduled  monthly  payments.  Thereafter,  the
interest rates are subject to periodic adjustment based on changes in an index.

ARMs have minimum and maximum rates beyond which the mortgage  interest rate may
not vary over the  lifetime of the loan.  Certain  ARMs  provide for  additional
limitations on the maximum amount by which the mortgage interest rate may adjust
for any  single  adjustment  period.  Negatively  amortizing  ARMs  may  provide
limitations on changes in the required monthly  payment.  Limitations on monthly
payments can result in monthly payments that are greater or less than the amount
necessary  to  amortize  a  negatively  amortizing  ARM by its  maturity  at the
interest rate in effect during any particular month.

There are two types of indexes that provide the basis for ARM rate  adjustments:
those based on market rates and those based on a calculated  measure,  such as a
cost of funds index or a moving  average of mortgage  rates.  Commonly  utilized
indexes include the one-year,  three-year,  and five-year constant maturity U.S.
Treasury  rates (as  reported by the Federal  Reserve  Board);  the  three-month
Treasury  bill  rate;  the  180-day  Treasury  bill rate;  rates on  longer-term
Treasury securities;  the Eleventh District Federal Home Loan Bank Cost of Funds
Index  (EDCOFI);  the  National  Median  Cost of  Funds  Index;  the  one-month,
three-month,  six-month,  or one-year London Interbank Offered Rate (LIBOR);  or
six-month  CD  rates.  Some  indexes,  such as the  one-year  constant  maturity
Treasury rate or three-month LIBOR, are highly correlated with changes in market
interest rates. Other indexes, such as the EDCOFI, tend to lag behind changes in
market rates and be somewhat less

volatile over short periods of time.

The EDCOFI  reflects the monthly  weighted  average cost of funds of savings and
loan  associations  and savings banks whose home offices are located in Arizona,
California,  and Nevada (the Federal Home Loan Bank  Eleventh  District) and who
are member institutions of the Federal Home Loan Bank of San Francisco (the FHLB
of San Francisco),  as computed from  statistics  tabulated and published by the
FHLB of San Francisco.  The FHLB of San Francisco normally announces the Cost of
Funds Index on the last  working day of the month  following  the month in which
the cost of funds was incurred.

One-year and three-year Constant Maturity Treasury (CMT) rates are calculated by
the  Federal  Reserve  Bank of New York,  based on daily  closing  bid yields on
actively traded Treasury  securities  submitted by five leading  broker-dealers.
The median bid yields are used to construct a daily yield curve.

The National  Median Cost of Funds Index,  similar to the EDCOFI,  is calculated
monthly by the Federal Home Loan Bank Board (FHLBB) and  represents  the average
monthly  interest  expenses on  liabilities  of member  institutions.  A median,
rather than an arithmetic mean, is used to reduce the effect of extreme numbers.

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

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


Zero-Coupon   Securities  (Short-Term  Treasury,   Intermediate-Term   Treasury,
Long-Term Treasury and Inflation Fund) 
Zero-coupon  U.S.  Treasury  securities are the unmatured  interest  coupons and
underlying  principal  portions of U.S.  Treasury  notes and bonds.  Originally,
these  securities were created by  broker-dealers  who bought Treasury notes and
bonds and deposited these  securities with a custodian bank. The  broker-dealers
then sold receipts representing  ownership interests in the coupons or principal
portions of the notes and bonds.  Some examples of zero-coupon  securities  sold
through custodial receipt programs are CATS (Certificates of Accrual on Treasury
Securities),  TIGRs  (Treasury  Investment  Growth  Receipts),  and  generic TRs
(Treasury Receipts).
    

The U.S. Treasury  subsequently  introduced a program called Separate Trading of
Registered  Interest and  Principal of  Securities  (STRIPS).  In this  program,
eligible  securities  may be presented to the U.S.  Treasury and  exchanged  for
their component  parts,  which are then traded in book-entry  form.  (Book-entry
trading eliminated the bank credit risks associated with broker-dealer sponsored
custodial  receipt   programs.)  STRIPS  are  direct  obligations  of  the  U.S.
government and have the same credit risks as other U.S. Treasury securities.

Principal  and interest on bonds issued by the  Resolution  Funding  Corporation
(REFCORP) have also been separated and issued as stripped  securities.  The U.S.
government  and its agencies may issue  securities in  zero-coupon  form.  These
securities are referred to as "original issue zero-coupon securities."

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  from the board of  trustees  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 Funds.

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

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

   
On behalf of the Funds,  the Manager  transacts  in round lots  ($100,000 to $10
million or more)  whenever  possible.  Since  commissions  are not  charged  for
round-lot transactions of U.S. Treasury securities, the Funds' transaction costs
consist solely of custodian charges and dealer mark-ups.  Each Fund may hold its
portfolio securities to maturity or sell or swap them for others, depending upon
the level and slope of, and anticipated  changes in, the yield curve.  The Funds
paid no brokerage commissions during the fiscal year ended March 31, 1996.

Highlights appearing in the Prospectus.


VALUATION OF PORTFOLIO SECURITIES
Each Fund's net asset value per share ("NAV") is calculated by American  Century
Services  Corporation (the "transfer agent"), as of the close of business of the
New York Stock  Exchange  (the  "Exchange")  each day the  Exchange  is open for
business,  usually at 3:00 p.m.  Central Time.  The Exchange has  designated the
following holiday closings for 1996: New Year's Day (observed), Presidents` Day,
Good Friday,  Memorial Day,  Independence Day, Labor Day,  Thanksgiving Day, and
Christmas Day  (observed).  Although the transfer agent expects the same holiday
schedule  to be  observed in the  future,  the  Exchange  may modify its holiday
schedule at any time.
    

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

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

The amortized  cost valuation  method is permitted in accordance  with Rule 2a-7
under the 1940 Act.  Under the Rule, a fund such as Government  Agency,  holding
itself out as a money market fund,  must adhere to certain  quality and maturity
criteria which are described in the Prospectus.

The trustees have established  procedures  designed to stabilize,  to the extent
reasonably  possible,   Government  Agency's  NAV  at  $1.00  per  share.  These
procedures  require the Fund's  chief  financial  officer to notify the trustees
immediately if, at any time, the Fund's  weighted  average  maturity  exceeds 60
days, or its NAV, as determined by using available market  quotations,  deviates
from its  amortized  cost per share by .25% or more. If such  deviation  exceeds
 .40%,  a meeting of the board of  trustees'  audit  committee  will be called to
consider what action,  if any, should be taken. If such deviation  exceeds .50%,
the Fund's  chief  financial  officer is  instructed  to adjust  daily  dividend
distributions  immediately  to the extent  necessary to reduce the  deviation to
 .50% or lower and to call a meeting of the board of trustees to consider further
action.
    

Actions the board may  consider  under these  circumstances  include (a) selling
portfolio   securities   prior  to  maturity,   (b)  withholding   dividends  or
distributions from capital, (c) authorizing a one-time dividend adjustment,  (d)
discounting  share purchases and initiating  redemptions in kind, or (e) valuing
portfolio securities at market for purposes of calculating NAV.

Most  securities held by the  Variable-Price  Funds are valued at current market
value as provided by an independent pricing service. Other securities are priced
at fair value as determined in good faith pursuant to guidelines  established by
the Fund's board of trustees.


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

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

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

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

For the  seven-day  period  ended March 31,  1996,  the Agency  Fund's yield was
4.73%, and its effective yield was 4.84%.

For the  Variable-Price  Funds,  yield  quotations  are based on the  investment
income per share earned during a particular 30-

day period, less expenses accrued during the period (net investment income), and
are computed by dividing the Fund's net investment  income by its share price on
the last day of the period, according to the following formula:

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

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

Each Variable-Price  Fund's yield for the 30-day period ended March 31, 1996, is
indicated in the following table.

   
                  Fund                                              30-day Yield

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

Average annual total returns are calculated by determining the growth or decline
in value of a hypothetical  historical investment in a Fund over a stated period
and then  calculating  the annually  compounded  percentage rate that would have
produced  the same  result if the rate of growth  or  decline  in value had been
constant  throughout the period.  For example,  a cumulative return of 100% over
ten years would  produce an average  annual total return of 7.18%,  which is the
steady  annual rate that would equal 100%  growth on a  compounded  basis in ten
years.  While average  annual total returns are a convenient  means of comparing
investment alternatives, investors should realize that the Funds' performance is
not constant over time,  but changes from year to year,  and that average annual
returns   represent   averaged   figures  as  opposed  to  actual   year-to-year
performance.  The Funds'  average  annual  returns for the one-year,  five-year,
ten-year,  and  life-of-fund  periods ended March 31, 1996, are indicated in the
following table.

In addition to average annual total returns,  each Fund may quote  unaveraged or
cumulative total returns  reflecting the simple change in value of an investment
over a stated period.  Average annual and cumulative total returns may be quoted
as a  percentage  or as a  dollar  amount  and may be  calculated  for a  single
investment,  a series of investments,  or a series of redemptions  over any time
period.  Total  returns may be broken down into their  components  of income and
capital  (including  capital  gains  and  changes  in share  price)  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 Funds'  performance  may be compared  with the  performance  of other mutual
funds  tracked by mutual  fund rating  services or with other  indexes of market

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,

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.  If an investor pays $10,000 to buy shares of a load
fund with an 8.5% sales charge,  $850 of that $10,000 is paid as a commission to
a salesperson,  leaving only $9,150 to put to work for the investor.  Over time,
the  difference  between  paying  a sales  load  and not  paying  one can have a
significant  effect on an  investor's  total return.  The Mutual Fund  Education
Alliance  provides a comparison of $10,000 invested in each of two mutual funds,
one with an 8.5% sales load and one without a sales load.  Assuming a compounded
annual growth rate of 10% for both  investments,  the no-load fund investment is
worth  $25,937  after ten  years,  and the load fund  investment  is worth  only
$23,732.


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

Amounts not  distributed  on a timely basis in  accordance  with a calendar year
distribution  requirement  are subject to a  nondeductible  4% excise tax at the
Fund level. To avoid the tax, a Fund must  distribute  during each calendar year
an  amount  equal to the sum of (a) at least  98% if its  ordinary  income  (not
taking into account any capital gains or losses) for the calendar  year,  (b) at
least 98% of its capital gains in excess of capital losses (adjusted for certain
ordinary  losses) for a one-year  period  generally  ending on October 31 of the
calendar year, and (c) all ordinary  income and capital gains for previous years
that were not distributed during such years.

Under the Code,  dividends  derived from interest,  and any  short-term  capital
gains, are federally  taxable to shareholders as ordinary income,  regardless of
whether such  dividends are taken in cash or  reinvested  in additional  shares.
Distributions  made  from a Fund's  net  realized  long-term  capital  gains and
designated as capital gain  dividends are taxable to  shareholders  as long-term
capital  gains,  regardless  of the length of time  shares  are held.  Corporate
investors are not eligible for the dividends-received  deduction with respect to
distributions from the Funds. A distribution will be treated as paid on December
31st of a calendar  year if it is  declared  by a Fund in  October,  November or
December  of the year  with a record  date in such a month  and paid by the Fund
during  January of the following  year.  Such  distributions  will be taxable to
shareholders in the calendar year the  distributions  are declared,  rather than
the calendar year in which the distributions are received.

Upon  redeeming,  selling,  or  exchanging  shares of a  Variable-Price  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 to the extent of capital gain dividends paid (or deemed paid).

   
As of March 31,  1996,  capital  loss  carryovers  were as  follows:  $7,505,846
(Intermediate-Term  Treasury),  $857,191 (Long-Term Treasury),  $69,205,630 (ARM
Fund),  and $23,041,420  (GNMA Fund). All loss carryovers will expire during the
period March 31, 2000 through  March 31, 2004. A Fund will not make capital gain
distributions to its shareholders  until all of its capital loss carryovers have
been offset or expired.

The Funds may  invest in  obligations  issued at a  discount.  In that  case,  a
portion of the discount element  generally is included in the Fund's  investment
company  taxable  income in each taxable period in which the obligation is held.
Such  amounts are subject to the Fund's  tax-related  distribution  requirements
even if not received by the Fund in cash in that period.

   
Dividends  paid by Government  Agency,  Short-Term  Treasury,  Intermediate-Term
Treasury,  and Long-Term  Treasuryare exempt from state personal income taxes in
all states to the extent these Funds derive their income from debt securities of
the U.S. government, whose interest payments are state tax-exempt.
    

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


   
ABOUT THE TRUST
American Century  Government  Income Trust,  formerly known as Benham Government
Income Trust, was organized as a Massachusetts  business trust on July 24, 1985.
Currently,   there  are  seven   series  of  the  Trust  as  follows:   American
Century-Benham  Government  Agency Money Market  Fund,  American  Century-Benham
Short-Term Treasury Fund,  American  Century-Benham  Intermediate-Term  Treasury
Fund, American  Century-Benham  Long-Term Treasury Fund, American Century-Benham
Adjustable Rate Government  Securities Fund,  American  Century-Benham GNMA Fund
and  American  Century-Benham  Inflation-Adjusted  Treasury  Fund.  The board of
trustees may create additional series from time to time.
    

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

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

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

INVESTMENT ADVISORY SERVICES
The Funds have 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 a wholly owned subsidiary of ACC, a
Delaware  corporation.  The Manager , as well as its  affiliates,  became wholly
owned  subsidiaries of ACC on June 1, 1995, upon the merger of Benham Management
International (BMI), the former parent of the Manager, into ACC. 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 and is investment
advisor to many of American Century's mutual funds.

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 a majority of the Fund's
shareholders  or by vote of a majority  of the  Trust's  trustees,  including  a
majority  of  those  trustees  who are  neither  parties  to the  agreement  nor
interested persons of any such party, cast in person at a meeting called for the
purpose of voting on such approval.

Each Fund's agreement is terminable on sixty 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 objectives, policies, and restrictions. The Manager determines
what  securities  will be purchased  and sold by the Fund and assist the Trust's
officers in carrying out decisions made by the board of trustees.

For these services, each Fund pays the Manager a monthly investment advisory fee
based on a percentage  of the Trust's  average daily net assets to the following
investment advisory fee 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
               .19% of average daily net assets over $6.5 billion

              ADMINISTRATIVE SERVICES AND TRANSFER AGENCY AGREEMENT

                                The Benham Group

     AGREEMENT effective as of the 3rd day of September, 1996, by each open-end
management investment company listed on Schedule E attached hereto and made part
of this agreement by reference, each portfolio of an open-end management
investment company listed on Schedule E and all open-end management investment
companies (or portfolios thereof) subsequently established and made subject to
this Agreement in accordance with Paragraph XI. (individually, "Fund" or
collectively, "Funds"), and Twentieth Century Services, Inc. ("TCS"), a
registered transfer agent incorporated under the laws of the State of California
and a wholly-owned subsidiary of TWENTIETH CENTURY COMPANIES, INC. ("TCC"), for
general administrative, transfer agency, and dividend disbursing services as
follows:

I. ADMINISTRATIVE SERVICES.

     A.   Description of Services. As consideration for the compensation
          described in Section I.B, TCS agrees to provide the Funds with the
          services described and set forth on Schedule A attached hereto and
          made a part of this Agreement by reference.

     B.   Compensation. As consideration for the services described in Section
          I.A above, each Fund shall pay TCS a fee equal to its pro rata share
          of the dollar amount derived from applying the aggregate average daily
          net assets of the Funds listed on Schedule E to the rate schedule set
          forth on Schedule F attached hereto and made a part of this Agreement
          by reference ("fund-level fee"). Each Fund's fund-level fee, or pro
          rata share of the dollar amount derived from applying the Funds'
          aggregate average daily net assets to the rate schedule set forth on
          Schedule F, shall be determined on the basis of its average daily net
          assets relative to all other Funds listed on Schedule E. Said
          fund-level fees shall be calculated and accrued daily and payable
          monthly in three installments, the first on the tenth of the month (or
          the next business day, if not a business day), the second on the
          twentieth of the month (or the next business day, if not a business
          day), and the third not later than the third business day of the
          following month.

II. TRANSFER AGENT SERVICES.

     A.   Services to be Provided. As consideration for the compensation
          described in Section II.B, TCS will provide each Portfolio with the
          share transfer and dividend disbursing services described on Schedule
          B attached hereto and made a part of this Agreement by reference. TCS
          agrees to maintain sufficient trained personnel, equipment, and
          supplies to perform such services in conformity with the current
          prospectus of each Fund and such other reasonable standards of
          performance as the Funds may from time to time specify, and otherwise
          in an accurate, timely, and efficient manner.

     B.   Compensation. As consideration for the services described in Section
          II.A, each Fund agrees to pay TCS the fees specified on Schedule F for
          each shareholder account maintained and each shareholder account
          transaction executed by TCS each month. For purposes of this Agreement
          "shareholder account transaction" is any one of the transactions
          described on Schedule C attached hereto and made a part of this
          Agreement by reference, as it may be amended from time to time. Such
          fees shall be paid monthly in three installments, the first on the
          tenth of the month (or the next business day, if not a business day),
          the second on the twentieth of the month (or the next business day, if
          not a business day), and the third on the third business day of the
          following month.

     C.   Third Party Servicing. Subject to approval by the applicable Fund's
          Board of Directors/Trustees, TCS may enter into agreements with third
          parties for the performance of one or more of its obligations under
          this Agreement (and such other services as TCS may desire) for all or
          any portion of the shareholders of the Fund who maintain shareholder
          accounts through, or who are otherwise provided services by, any such
          third parties. To the extent that such third parties perform services
          that TCS is obligated to perform under this Agreement, TCS shall be
          entitled to receive the fees to which it would otherwise be entitled
          hereunder had it performed such services directly; provided, however,
          that the Fund's Board of Directors/Trustees may limit amounts
          receivable by TCS under this Agreement for services performed on its
          behalf by third parties. TCS will furnish the Fund shareholder and
          account records and data upon which the Fund's obligations under this
          Agreement are calculated, and such other data pertaining to any
          services rendered by third parties as the Fund may reasonably require.
          The Fund shall be entitled to have any and all such records audited by
          the Fund's independent accountants at any time upon reasonable notice
          to TCS.
             
III. EXPENSES.

     A.   Expenses of TCS. TCS shall pay all expenses incurred in providing the
          Funds the services and facilities described in this Agreement, whether
          or not such expenses are billed to TCS or the Funds.

          Directors/Trustees, shall pay (or reimburse TCS for payment of) the
          following expenses, which shall be categorized as Extraordinary
          Expenses and shall be excluded from each Fund's expense ratio, whether
          or not the expense was billed to the Funds, TCS, or any related
          entity:

          1.   Brokerage commissions

          2.   Taxes

IV. TERM. With respect to each Fund, this Agreement shall become effective upon
its approval by vote of a majority of the Fund's shareholders at a meeting
called for the purpose of voting on such approval and a majority of the Fund's
Directors/Trustees, including a majority of those Directors/Trustees who are not
"interested persons" of the Fund or TCS (as that term is defined in the
Investment Company Act of 1940), and shall continue until it is terminated
pursuant to the provisions of Paragraph XII.

V. INSURANCE. The Funds and TCS agree to procure and maintain, separately or as
joint insureds with their Directors/Trustees, employees, agents, and others, an

Investment Company Act of 1940 in such amounts and with such deductibles as are
set forth on Schedule D attached to this Agreement and made a part hereof by
reference, as it may be amended from time to time, and to pay premiums therefor,
provided that if a Fund or TCS is party to a policy in which it is named as a
joint insured, its liability for premiums on said policy shall be determined on
the basis of premiums it would pay to obtain equivalent coverage separately
relative to the premiums each other joint insured would pay to obtain equivalent
coverage separately.

VI. REGISTRATION AND COMPLIANCE.

     A.   TCS represents that it is registered as a transfer agent with the
          Securities and Exchange Commission ("SEC") pursuant to ss.17A of the
          Securities Exchange Act of 1934 and the rules and regulations
          thereunder, and agrees to maintain said registration and comply with
          all of the requirements of said Act, rules, and regulations so long as
          this Agreement remains in force.

     B.   Each Fund represents that it is an open-end management investment
          company registered with the SEC under the Securities Act of 1933 and
          the rules and regulations thereunder and the Investment Company Act of
          1940 and the rules and regulations thereunder, and that it is
          authorized to sell its shares pursuant to said Acts, and the rules and
          regulations thereunder.

          Each Fund will furnish TCS with a list of those jurisdictions in the
          United States and elsewhere in which it is authorized to sell its
          shares to the general public and maintain the currency of said list by
          amendment. Each Fund agrees to promptly advise TCS of any change in or
          limitation upon its authority to carry on business as an investment
          company pursuant to said Acts, and the statutes, rules, and
          regulations of each and every jurisdiction in which its shares are
          registered for sale.

VII. DOCUMENTATION. Each of the Funds and TCS shall supply to the other upon
request such documentation as is required by them to carry out their respective
obligations under this Agreement, including, but not limited to, declarations of
trust, articles of incorporation, bylaws, codes of ethics, registration
statements, permits, financial reports, third party audits, certificates of
authority, computer tapes, and related items.

VIII. PROPRIETARY INFORMATION. It is agreed that all records and documents,
except computer data processing programs and any related documentation used or
prepared by, or on behalf of, TCS for the performance of its services hereunder,
are the property of the Funds and shall be open to audit or inspection by the
Funds or their duly authorized agents during the normal business hours of TCS,
shall be maintained in such fashion as to preserve the confidentiality thereof
and to comply with applicable federal and state laws and regulations, and shall,
in whole or any specified part, be surrendered and turned over to the Funds or
their duly authorized agents upon receipt by TCS of reasonable notice of and
request therefor.

IX. INDEMNITY. Each Fund shall indemnify and hold TCS harmless against any
losses, claims, damages, liabilities, or expenses (including reasonable counsel
fees and expenses) resulting from any claim, demand, action, or suit brought by
any person other than the Fund (including a shareholder naming the Fund as a
party) and not resulting from TCS's bad faith, willful misfeasance, reckless
disregard of its obligations and duties, negligence, or breach of this
Agreement, and arising out of, or in connection with:

     A.   TCS's performance of its obligations under this Agreement;

     B.   Any error or omission in any record (including but not limited to
          magnetic tapes, computer printouts, hard copies, and microfilm or
          microfiche copies) delivered, or caused to be delivered, by a Fund to
          TCS in connection with this Agreement;

     C.   Bad faith, willful misfeasance, reckless disregard of its obligations
          and duties, or negligence on the part of the Fund, or TCS's acting
          upon any instructions reasonably believed by it to have been properly
          executed or communicated by any person duly authorized by the Fund;

     D.   TCS's acting in reliance upon advice reasonably believed by it to have
          been given by counsel for the Funds, or;

     E.   TCS's acting in reliance upon any instrument reasonably believed by it
          to have been genuine and signed, countersigned, or executed by the
          proper person(s) in accordance with the currently effective
          certificate(s) of authority delivered to TCS by the Funds

               In the event that TCS requests a Fund to indemnify or hold it
          harmless hereunder, TCS shall use its best efforts to inform the Fund
          of the relevant facts concerning the matter in question. TCS shall use
          reasonable care to identify and promptly notify the Fund concerning
          any matter which presents, or appears likely to present, a claim for
          indemnification against the Fund.

               Each Fund may elect to defend TCS against any claim which may be
          the subject of indemnification hereunder. In the event that the Fund
          makes such an election, it shall notify TCS and shall take over
          defense of the claim and, if so requested by the Fund, TCS shall incur
          no further legal or other expenses related thereto for which it is
          entitled to indemnity hereunder; provided, however, that nothing
          herein shall prevent TCS from retaining, at its own expense, counsel
          to defend any claim. Except with the applicable Fund's prior consent,
          TCS shall not confess to any claim or make any compromise in any
          matter in which the Fund will be asked to indemnify or hold TCS
          harmless hereunder without the Fund's prior consent.

X. LIABILITY.

     A.   Damages. TCS shall not be liable to any Fund, or any third party, for
          punitive, exemplary, indirect, special, or consequential damages (even
          if TCS has been advised of the possibility of such damages) arising
          from the performance of its obligations under this Agreement,
          including but not limited to loss of profits, loss of use of the
          shareholder accounting system, cost of capital, and expenses for
          substitute facilities, programs, or services.

     B.   Force Majeure. Any provision in this Agreement to the contrary
          notwithstanding, TCS shall not be liable for delays or errors
          occurring by reason of circumstances beyond its control or the control
          of any of its affiliates and not attributable to the negligence of TCS
          or any of its affiliates, including, but not limited to, acts of civil
          or military authority, national emergencies, national or regional work
          stoppages, fire, flood, catastrophe, earthquake, acts of God,
          insurrection, war, riot, failure of communication systems, or
          interruption of power supplies.

     C.   Trust Series Sole Obligor. TCS is expressly put on notice that, for
          any Fund which is a series of a registered investment company
          organized as a Massachusetts business trust (a "Trust Series"),
          liability under this Agreement shall be limited to the Trust Series
          incurring such liability and to the assets of such Trust Series. TCS
          shall not have any rights or remedies against any trustee, officer,
          employee, or shareholder of the Trust Series or any other series of
          the Trust for breach of this Agreement nor recourse to the property of
          any such persons or other series of the Trust for satisfaction of any
          judgment or other claim against the Trust Series.

XI. AMENDMENT. This Agreement and the Schedules forming a part hereof may be
amended at any time, with or without shareholder approval (except as otherwise
required by law), by a document signed by each of the parties hereto. In the
event that one or more additional Funds are established, and the governing
bodies of said Funds by resolution indicate that the Funds are to be made
parties to this Agreement, Schedule E hereto shall be amended to reflect the
addition of such new Funds, and such new Funds shall become parties hereto. Any
change in a Fund's registration statement or other compliance documents, or in
the forms relating to any plan, program, or service offered by its current
prospectus which would require a change in TCS's obligations hereunder shall be
subject to TCS's approval, which shall not be unreasonably withheld.

XII. TERMINATION. This Agreement may be terminated by any Fund with respect to
said Fund, or by TCS, without cause, upon 120 days' written notice to the other
party, and at any time for cause in the event that such cause remains unremedied
for more than 30 days after receipt by the other party of written specification
