An Overview of the Funds

What are the funds' investment goals?

These funds are asset  allocation  funds.  They seek  different  proportions  of
regular income and long-term  capital growth by investing in different  mixes of
asset types, such as stocks, bonds and money market instruments.

What are the funds' primary investment strategies and principal risks?

The  following  table  indicates  each  fund's  neutral  mix.  The  neutral  mix
represents  a  benchmark  as to  how a  fund's  investments  generally  will  be
allocated among the major asset classes over the long term.

                       Equity            Fixed Income or
                       Securities        Debt Securities      Cash
Fund                   (Stocks)          (Bonds)              Equivalents
- -----------------------------------------------------------------------------
Strategic Allocation:
Conservative            40%               45%                 15%
- -----------------------------------------------------------------------------
Strategic Allocation:
Moderate                60%               30%                 10%
- -----------------------------------------------------------------------------
Strategic Allocation:
Aggressive              75%               20%                  5%

   
In selecting  stocks for the equity portion of the funds, the advisor may choose
stocks of U.S.  or  foreign  companies  of any size.  The  advisor  invests  the
fixed-income portion of the funds primarily in investment-grade debt securities.

The funds' principal risks include

* Market  Risk--The  value of a fund's  shares  will go up and down based on the
  performance  of the  companies  whose  securities  it owns and  other  factors
  affecting the securities market generally.

* Interest  Rate  Risk--When  interest  rates  change,  the value of the  funds'
  fixed-income securities will be affected.

* Principal  Loss--As with all mutual funds,  if you sell your shares when their
  value is less than the price you paid, you will lose money.
    

Who may want to invest in the funds?

The funds may be a good investment if you are

* seeking funds that combine the potential for long-term capital growth with
  income

* seeking the convenience of funds that invest in both equity and fixed-income
  securities

* comfortable with the risks associated with the funds' investment strategy

* investing through an IRA or other tax-advantaged retirement plan

Who may not want to invest in the funds?

The funds may not be a good investment if you are

* not seeking current income from your investment

* investing for a short period of time

* uncomfortable with volatility in the value of your investment

An  investment  in the  funds  is  not a bank  deposit  and  is not  insured  or
guaranteed  by the Federal  Deposit  Insurance  Corporation  (FDIC) or any other
government agency.

Information about the Funds

Strategic Allocation: Conservative Fund
Strategic Allocation: Moderate Fund
Strategic Allocation: Aggressive Fund

What are the funds' investment objectives?

The funds are asset allocation funds. That is, they diversify their assets among
various  classes  of  investments  such  as  stocks,   bonds  and  money  market
instruments.  Each fund holds a different mix of these asset types,  which gives
it a distinct risk profile and return potential.

*   Strategic Allocation: Conservative seeks regular income through its emphasis
    on bonds and money market securities. It also has the potential for moderate
    long-term total return as a result of its stake in equity securities.

*   Strategic  Allocation:  Moderate  seeks  long-term  capital growth with some
    regular  income.  It  emphasizes  investments  in  equity  securities,   but
    maintains a sizeable stake in bonds and money market securities.

*   Strategic Allocation: Aggressive seeks long-term capital growth with a small
    amount of  income.  It  emphasizes  investments  in equity  securities,  but
    maintains a portion of its assets in bonds and money market securities.

You should be aware that the names of the three asset  allocation  funds offered
in this  Prospectus  are  intended  to reflect  the  relative  short-term  price
volatility  risk  among  the  funds and not as an  indication  of the  advisor's
assessment  of the  riskiness  of the funds as compared to other  mutual  funds,
including other mutual funds within the American Century family of funds.

How do the funds pursue their investment objectives?

The funds' strategic asset allocation  strategy  diversifies  investments  among
equity securities,  bonds and cash-equivalent  instruments. The funds may invest
in any type of U.S. or foreign  equity  security that meets certain  fundamental
and  technical   standards.   The  fund  advisor  draws  on  growth,  value  and
quantitative  investment techniques in managing the equity portion of the funds'
portfolios and diversifies the funds' equity investments among small, medium and
large companies.

   
The growth  strategy looks for companies with earnings and revenues that are not
only growing, but growing at a successively faster, or accelerating,  pace. This
strategy  is based on the  premise  that,  over the long  term,  the  stocks  of
companies with  accelerating  earnings and revenues have a  greater-than-average
chance to increase  in value.  The value  investment  discipline  seeks  capital
growth by investing in equity securities of well-established  companies that the
funds' managers believe to be temporarily undervalued.  The primary quantitative
management  technique the managers use is portfolio  optimization.  The managers
may   construct  a  portion  of  the  funds'   portfolios   to  match  the  risk
characteristics  of the S&P 500 and then optimize each  portfolio to achieve the
desired balance of risk and return potential.
    

Although the funds will remain exposed to each of the investment disciplines and
categories  described above, a particular  discipline or investment category may
be  emphasized  when, in the managers'  opinion,  such  discipline or investment
category is undervalued relative to the other disciplines or categories.

   
The funds also invest in a variety of debt  securities  payable in both U.S. and
foreign currencies.  The funds primarily invest in investment-grade  securities,
that is, securities rated in the four highest  categories by independent  rating
organizations.  However,  Strategic Allocation:  Moderate may invest up to 5% of
its assets,  and Strategic  Allocation:  Aggressive  may invest up to 10% of its
assets,  in  high-yield  securities.  High-yield  securities  are  higher  risk,
nonconvertible debt obligations that are rated below investment-

grade.  The funds may also  invest in  unrated  securities  based on the  funds'
advisor's  assessment of their credit  quality.  The maturities of  fixed-income
securities in which the funds invest are expected to range from two to 30 years.
    

The  funds  may  invest  the cash  equivalent  portion  of their  portfolios  in
high-quality  money market  investments  (denominated in U.S. dollars or foreign
currencies).

The following  table shows the  operating  ranges in which each fund's asset mix
may vary over short-term periods.  These variations may be due to differences in
asset class performance or prevailing market conditions.

- -------------------------------------------------------------------------------
Strategic Allocation:
Moderate                      50-70%          20-40%                5-20%

What are the primary risks of investing in the fund?

The value of the funds'  shares  depends on the value of the  stocks,  bonds and
other securities they own.

The value of the individual  equity securities the funds own will go up and down
depending on the  performance of the companies that issued them,  general market
and economic conditions, and investor confidence.

The value of the funds' fixed income  securities  will be affected  primarily by
rising or falling  interest  rates and the  continued  ability of the issuers of
these securities to make payments of interest and principal as they become due.

When interest  rates  change,  the amount of income the fund  generates  will be
affected.  Generally,  when interest  rates rise, the funds income and its share
value will decline. The opposite is true when interest rates decline.

   
The  lowest-rated  investment-grade  bonds in which the funds may invest contain
some speculative  characteristics.  Having those bonds in the funds'  portfolios
means the  funds'  value may go down more if  interest  rates or other  economic
conditions  change  than if the funds  contained  only  higher-rated  bonds.  In
addition,  Strategic Allocation:  Moderate and Strategic Allocation:  Aggressive
may invest in higher-risk high-yield  securities,  sometimes referred to as junk
bonds.  These securities are considered to be predominantly  speculative and are
more likely to be  negatively  affected  by changes in  interest  rates or other
economic conditions.
    

As with all funds,  at any given time, the value of your shares of the funds may
be worth more or less than the price you paid.  If you sell your shares when the
value is less than the price you paid, you will lose money.

Although  the  fund  advisor  invests  the  funds'  assets   primarily  in  U.S.
securities,  the funds can invest in  securities of foreign  companies.  Foreign
securities can have certain  unique risks,  including  fluctuations  in currency
exchange rates, unstable political and economic structures, reduced availability
of public information and the lack of uniform financial reporting and regulatory
practices  similar to those  that  apply to U.S.  issuers.  These  factors  make
investing  in  foreign  securities  generally  riskier  than  investing  in U.S.
securities.  To the extent the funds invest in foreign  securities,  the overall
risk of the funds could be affected.

   
These funds are intended for investors who seek to diversify  their assets among
various  classes  of  investments,  such  as  stocks,  bonds  and  money  market
instruments,  and who are willing to accept the risks associated with the funds'
investment strategies.

Fixed-income  securities are rated by nationally  recognized  securities ratings
organizations  (SROs),  such as Moody's and Standard & Poor's.  Each SRO has its
own system for  classifying  securities,  but each tries to indicate a company's
ability  to  make  timely  payments  of  interest  and  principal.   A  detailed
description  of SRO's,  their ratings  system and what we do if a security isn't
rated is included in the Statement of Additional Information.

Management

Who manages the funds?

The Board of Directors,  investment  advisor and fund  management  team play key
roles in the management of the funds.

The Board of Directors

   
The Board of Directors  oversees the  management of the funds and meets at least
quarterly  to  review  reports  about  fund  operations.  Although  the Board of
Directors  does not manage the funds,  it has hired an investment  advisor to do
so. More than two-thirds of the Directors are independent of the funds' advisor;
that is, they are not employed by and have no financial interest in the advisor.
    

The Investment Advisor

The funds' investment  advisor is American Century Investment  Management,  Inc.
The advisor has been  managing  mutual  funds  since 1958.  American  Century is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible  for managing the investment  portfolios of the funds
and directing the purchase and sale of their investment securities.  The advisor
also arranges for transfer agency,  custody and all other services necessary for
the funds to operate.

For the  services it provided to the funds  during the most recent  fiscal year,
the  advisor  received a unified  management  fee based on a  percentage  of the
average net assets of the Investor  Class of shares of each fund.  The amount of
the  management  fee is  calculated  on a  class-by-class  basis  daily and paid
monthly.

   
Out of that fee, the advisor paid all  expenses of managing  and  operating  the
funds  except  brokerage  expenses,  taxes,  interest,  fees and expenses of the
independent directors (including legal counsel fees) and extraordinary expenses.
A  portion  of  the  management  fee  may  be  paid  by the  funds'  advisor  to
unaffiliated third parties who provide recordkeeping and administrative services
that would otherwise be performed by an affiliate of the advisor.
    

Management Fees Paid by the Funds to the Advisor as a Percentage of Average Net
Assets for the Most Recent Fiscal Year Ended November 30, 1998

American  Century has a Code of Ethics  designed to ensure that the interests of
fund  shareholders  come before the interests of the people who manage the fund.
Among other  provisions,  the Code of Ethics  prohibits  portfolio  managers and
other investment  personnel from buying securities in an initial public offering
or from  profiting  from the  purchase and sale of the same  security  within 60
calendar days. In addition,  the Code of Ethics requires  portfolio managers and
other  employees  with  access  to  information  about the  purchase  or sale of
securities by the funds to obtain approval before executing  permitted  personal
trades.

Fundamental Investment Policies

Fundamental  investment  policies  contained  in  the  Statement  of  Additional
Information  and the  investment  objectives  of the  funds  may not be  changed
without a shareholder vote. The Board of Directors may change any other policies
and investment strategies.

Year 2000 Issues

Many of the world's  computer  systems  currently  cannot properly  recognize or
process date-sensitive information relating to the Year 2000 and beyond. Because
this may impact the computer systems of various American  Century-affiliated and
external service providers for the funds,  American Century formally initiated a
Year 2000  readiness  project in July 1997.  It  involves a team of  information
technology  professionals  assisted  by  outside  consultants  and  guided  by a
senior-level steering committee.  The team's goal is to assess the impact of the
Year 2000 on  American  Century's  systems,  renovate  or  replace  noncompliant
critical systems and test those systems. In addition,  the team has been working
to gather  information  about the Year 2000  efforts of the funds'  other  major
service providers.

Although  American Century believes its critical systems will function  properly
in the Year 2000, this is not guaranteed.  If the efforts of American Century or
its  external  service  providers  are  not  successful,  the  funds'  business,
particularly the provision of shareholder services, may be hampered.

   
In  addition,  the  issuers  of  securities  the funds own could  have Year 2000
computer problems. Foreign issuers, especially those in emerging markets, may be
more  susceptible  to such  problems than U.S.  issuers.  These  problems  could
negatively affect the value of issuers' securities, which, in turn, could impact
the funds' performance. The advisor has established a process to gather publicly
available  information about the Year 2000 readiness of these issuers.  However,
this  process may not  uncover all  relevant  information,  and the  information
gathered  may not be complete  and  accurate.  Moreover,  an issuer's  Year 2000
readiness is only one of many factors the fund managers may consider when making
investment decisions, and other factors may receive greater weight.

Qualified Retirement Plans                                      $2,500*
    

* The  minimum  investment  requirements  may be  different  for  some  types of
retirement accounts.

If you  establish an automatic  investment  plan of at least $50 per month,  the
minimum may be waived.

   
Redemption of Shares in Low-Balance Accounts

If your  redemption  activity  causes  your  account  balance  to fall below the
minimum initial  investment  amount,  we will notify you and give you 90 days to
meet the minimum or to  establish an automatic  monthly  investment  of at least
$50. If you do not meet the deadline, American Century will redeem the shares in
the account and send the proceeds to your address of record.

Abusive Trading Practices

We do not permit market-timing or other abusive trading practices in our funds.

Excessive,  short-term  (market-timing)  or other abusive trading  practices may
disrupt portfolio management  strategies and harm fund performance.  To minimize
harm to the funds and their  shareholders,  we  reserve  the right to reject any
purchase order (including  exchanges) from any investor we believe has a history
of  abusive  trading  or  whose  trading,  in our  judgment,  has been or may be
disruptive to a fund. In making this judgment,  we may consider  trading done in
multiple  accounts under common ownership or control.  We also reserve the right
to delay  delivery of your  redemption  proceeds--up  to seven days--or to honor
certain redemptions with securities,  rather than cash, as described in the next
section.

Special Requirements for Large Redemptions

If,  during any 90-day  period,  you redeem fund shares worth more than $250,000
(or 1% of the assets of the fund if that percentage is less than  $250,000),  we
reserve  the right to pay part or all of the  redemption  proceeds  in excess of
this amount in readily marketable securities instead of cash. If we make payment
in securities,  we will value the securities,  selected by the fund, in the same
manner as we do in computing  the fund's net asset value.  We may provide  these
securities in lieu of cash without prior notice.

If your  redemption  would  exceed  this limit and you would like to avoid being
paid in  securities,  please  provide us with an  unconditional  instruction  to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur.  The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the  transaction.  This  minimizes the effect of the
redemption on the fund and its remaining shareholders.

Investing Through Financial Intermediaries

If you do business  with us through a  financial  intermediary  or a  retirement
plan,  your ability to purchase,  exchange and redeem  shares will depend on the
policies of that entity. Some policy differences may include

*  minimum investment requirements

*  exchange policies

*  fund choices

   
*  cutoff time for investments
    

Please  contact  your  financial  intermediary  or plan  sponsor  for a complete
description  of its policies.  Copies of the funds' annual  reports,  semiannual
reports  and  Statements  of  Additional  Information  are  available  from your
intermediary or plan sponsor.

Certain  financial  intermediaries  perform for their clients  recordkeeping and
administrative  services that would otherwise be performed by American Century's
transfer agent.  In some  circumstances,  American  Century will pay the service
provider a fee for performing those services.

Although  transactions in fund shares may be made directly with American Century
at no charge,  you also may purchase,  redeem and exchange  fund shares  through
financial  intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the intermediary and are not shared with
American Century or the funds.

   
American Century has contracts with certain financial  intermediaries  requiring
them to track  the time  investment  orders  are  received  and to  comply  with
procedures  relating to the  transmission  of orders.  The funds have authorized
those  intermediaries  to accept  orders on their behalf up to the time at which
the net asset value is determined.  If those orders are  transmitted to American
Century and paid for in accordance with the contract, they will be priced at the
net asset  value next  determined  after your  request is  received  in the form
required by the intermediary on a fund's behalf.
    

(left margin)
(graphic of hand with index finger pointing)
Financial intermediaries include banks, broker-dealers,  insurance companies and
investment advisors.

Share Price and Distributions

Share Price

   
American  Century  determines  the net asset  value (NAV) of the funds as of the
close of regular trading on the New York Stock Exchange  (usually 4 p.m. Eastern
time)  each day the  Exchange  is open.  On days when the  Exchange  is not open
(including  certain U.S.  holidays),  we do not  calculate the NAV. The NAV of a
fund share is the current  value of the fund's  assets,  minus any  liabilities,
divided by the number of fund shares outstanding.

If  current  market  prices  of  securities  owned  by a fund  are  not  readily
available,  the  advisor  may  determine  their  fair value in  accordance  with
procedures  adopted by the fund's Board of  Directors.  Trading of securities in
foreign  markets  may not take place on every day the  Exchange  is open.  Also,
trading in some foreign  markets may take place on weekends or holidays when the
fund's  NAV is not  calculated.  So, the value of the  fund's  portfolio  may be
affected on days when you can't purchase or redeem shares of the fund.
    

We will price your purchase,  exchange or redemption at the NAV next  determined
after we receive your transaction request in good order.

Distributions

Federal tax laws require each fund to make  distributions to its shareholders in
order  to  qualify  as a  "regulated  investment  company."  Qualification  as a
regulated  investment  company means that the funds will not be subject to state
or federal  income  tax on  amounts  distributed.  The  distributions  generally
consist of dividends and interest received, as well as capital gains realized on
the sale of investment securities.

   
The funds pay distributions of substantially all of their income quarterly, with
the exception of Strategic Allocation: Aggressive, which pays such distributions
annually.  Distributions  from realized capital gains are generally paid twice a
year,  usually  in  March  and  December.  The  funds  may  make  more  frequent
distributions,  if necessary,  to comply with Internal  Revenue Code provisions.
The funds'  distributions may be taxable as ordinary income,  capital gains or a
combination of the two.  Capital gains are taxed at different rates depending on
the length of time the fund held the  securities  that were sold.  Distributions
are  reinvested  automatically  in additional  shares unless you choose  another
option.

You will participate in fund distributions,  when they are declared, starting on
the day after your purchase is effective. For example, if you purchase shares on
a day that a distribution is declared,  you will not receive that  distribution.
If you redeem shares, you will receive any distribution  declared on the day you
redeem.  If you redeem all shares,  we will include any  distributions  received
with your redemption proceeds.

Participants in employer-sponsored retirement or savings plans must reinvest all
distributions.  For shareholders  investing  through taxable  accounts,  we will
reinvest  distributions unless you elect to receive them in cash. Please consult
your services guide for further  information  regarding  distributions  and your
distribution options.

The net asset value of the fund is the price of its shares.

Capital gains are increases in value of a capital asset, such as stock, from the
time the assets are purchased. Tax becomes due on capital gains once an asset is
sold.

Taxes

   
The tax  consequences  of  owning  shares of the funds  will vary  depending  on
whether you own them through a taxable or tax-deferred account. Tax consequences
result from  distributions  by a fund of  dividend  and  interest  income it has
received or capital gains it has generated  through its  investment  activities.
Tax  consequences  also result from sales of fund shares by investors  after the
net asset value has increased or decreased.

Tax-Deferred Accounts

If you purchase fund shares through a tax-deferred  account, such as an IRA or a
qualified  employer-sponsored  retirement  or savings  plan,  income and capital
gains  distributions  usually will not be subject to current taxation,  but will
accumulate in your account  under the plan on a  tax-deferred  basis.  Likewise,
moving  from one fund to  another  fund  within a plan or  tax-deferred  account
generally  will  not  cause  you to be  taxed.  For  information  about  the tax
consequences of making  purchases or withdrawals  through an  employer-sponsored
retirement  or  savings  plan,  or  through  an IRA,  please  consult  your plan
administrator, your summary plan description or a professional tax advisor.

Taxable Accounts
    

If you own fund shares through a taxable account,  distributions by the fund and
sales by you of fund shares may cause you to be taxed.

   
Taxability of Distributions

Fund distributions may consist of income earned by the fund from sources such as
dividends  and  interest,  or  capital  gains  generated  from  the sale of fund
investments. Distributions of income are taxed as ordinary income. Distributions
of capital gains are classified  either as short-term or long-term and are taxed
as follows:
    

<TABLE>
<CAPTION>
   
Type of Distribution        Tax Rate for 15% Bracket   Tax Rate for 28% Bracket or above
- ----------------------------------------------------------------------------------------
<S>                         <C>                        <C>
Short-term capital gains    Ordinary income rate       Ordinary income rate
- ----------------------------------------------------------------------------------------
Long-term capital gains     10%                        20%
</TABLE>

The tax status of any  distribution  of capital  gains is determined by how long
the fund held the  underlying  security that was sold,  not by how long you have
been  invested  in the  fund or  whether  you  reinvest  your  distributions  in
additional  shares or take them in cash.  American Century will send you the tax
status of fund  distributions  for each calendar year in an annual tax statement
from the fund.
    

Distributions  also may be subject to state and local taxes.  Because everyone's
tax situation is unique,  always  consult your tax  professional  about federal,
state and local tax consequences.

   
Taxes on Transactions

Your  redemptions -- including  exchanges to other American Century funds -- are
subject to capital  gains tax.  The table above can provide a general  guide for
your potential tax liability when selling or exchanging fund shares.  Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares  decrease in value,  their sale or exchange will result in a long-term or
short-term capital loss.
    

(left margin)
Buying a Dividend

Purchasing  fund shares in a taxable  account  shortly before a distribution  is
sometimes known as buying a dividend.  In taxable accounts,  you must pay income
taxes on the  distribution  whether you reinvest the  distribution or take it in
cash. In addition,  you will have to pay taxes on the  distribution  whether the
value of your  investment  decreased,  increased  or remained the same after you
bought the fund shares.

The risk in buying a dividend  is that a fund's  portfolio  may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. We distribute those gains to you, after  subtracting any losses,  even
if you did not own the shares when the gains occurred.

If you buy a  dividend,  you incur the full tax  liability  of the  distribution
period,  but you may not enjoy the full  benefit  of the gains  realized  in the
fund's portfolio.

Multiple Class Information

   
American  Century  offers two classes of the funds:  Investor  Class and Advisor
Class.  The shares offered by this Prospectus are Investor Class shares and have
no up-front or deferred charges, commissions or 12b-1 fees.

American  Century offers the Advisor Class of shares  primarily to institutional
investors   or   through   institutional    distribution   channels,   such   as
employer-sponsored   retirement  plans  or  through  banks,  broker-dealers  and
insurance  companies.  The Advisor Class has different  fees,  expenses,  and/or
minimum  investment  requirements than the Investor Class. The difference in the
fee structures between the classes is the result of their separate  arrangements
for shareholder and  distribution  services and not the result of any difference
in  amounts  charged  by the  advisor  for core  investment  advisory  services.
Accordingly,  the  core  investment  advisory  expenses  do not  vary by  class.
Different fees and expenses will affect performance.  For additional information
concerning the Advisor Class of shares not offered by this  Prospectus,  call us
at 1-800-345-3533,  or contact a sales representative or financial  intermediary
who offers that class of shares.

Except as  described  below,  all  classes  of  shares of a fund have  identical
voting,  dividend,   liquidation  and  other  rights,  preferences,   terms  and
conditions.  The only  differences  among the various classes are (a) each class
may be subject to different  expenses specific to that class, (b) each class has
a different identifying designation or name, (c) each class has exclusive voting
rights with respect to matters solely  affecting such class;  and (d) each class
may have different exchange privileges.

An Overview of the Funds

What are the funds' investment goals?

These funds are asset  allocation  funds.  They seek  different  proportions  of
regular income and long-term  capital growth by investing in different  mixes of
asset types, such as stocks, bonds and money market instruments.

What are the funds' primary investment strategies and principal risks?

The  following  table  indicates  each  fund's  neutral  mix.  The  neutral  mix
represents  a  benchmark  as to  how a  fund's  investments  generally  will  be
allocated among the major asset classes over the long term.

Neutral Mixes

                                              Fixed Income
                           Equity                 or
                           Securities        Debt Securities         Cash
Fund                       (Stocks)             (Bonds)            Equivalents

Strategic Allocation:
Conservative                 40%                  45%                   15%
- --------------------------------------------------------------------------------
Strategic Allocation:
Moderate                     60%                  30%                   10%
- --------------------------------------------------------------------------------
Strategic Allocation:
Aggressive                   75%                  20%                    5%

   
In selecting  stocks for the equity portion of the funds, the advisor may choose
stocks of U.S.  or  foreign  companies  of any size.  The  advisor  invests  the
fixed-income portion of the funds primarily in investment-grade debt securities.

The funds' principal risks include

*   Market  Risk--The  value of a fund's shares will go up and down based on the
    performance  of the  companies  whose  securities  it owns and other factors
    affecting the securities market generally.

*   Interest Rate  Risk--When  interest  rates  change,  the value of the funds'
    fixed-income securities will be affected.

*   Principal Loss--As with all mutual funds, if you sell your shares when their
    value is less than the price you paid, you will lose money.
    

Who may want to invest in the funds?

The funds may be a good investment if you are

* seeking funds that combine the potential for long-term capital growth with
  income

* seeking the convenience of funds that invest in both equity and fixed-income
  securities

* comfortable with the risks associated with the funds' investment strategy

* investing through an IRA or other tax-advantaged retirement plan

Who may not want to invest in the funds?

The funds may not be a good  investment if you are 

* not seeking current income from your investment

* investing for a short period of time

* uncomfortable with volatility in the value of your investment

An  investment  in the  funds  is  not a bank  deposit,  and is not  insured  or
guaranteed  by the Federal  Deposit  Insurance  Corporation  (FDIC) or any other
government agency.

funds have stepped fee schedules.  As a result,  the funds'  management fee rate
generally  decreases as fund assets  increase.  Please  consult the Statement of
Additional Information for more details about the funds' management fees.

2 The 12b-1 fee is designed to permit investors to purchase Advisor Class shares
through   broker-dealers,   banks,   insurance  companies  and  other  financial
intermediaries.  A portion  of the fee is used to  compensate  them for  ongoing
recordkeeping and  administrative  services that would otherwise be performed by
an  affiliate  of the  advisor,  and a portion  is used to  compensate  them for
distribution  and other  shareholder  services.  See "Service  and  Distribution
Fees," page 15.
    

3 Other expenses,  which include the fees and expenses of the fund's independent
directors,  their legal counsel,  interest and extraordinary expenses, were less
than 0.005% for the most recent fiscal year.

Information about the Funds

   
Strategic Allocation: Conservative Fund
Strategic Allocation: Moderate Fund
Strategic Allocation: Aggressive Fund
    

What are the funds' investment objectives?

The funds are asset allocation funds. That is, they diversify their assets among
various  classes  of  investments  such  as  stocks,   bonds  and  money  market
instruments.  Each fund holds a different mix of these asset types,  which gives
it a distinct risk profile and return potential.

*   Strategic Allocation: Conservative seeks regular income through its emphasis
    on bonds and money market securities. It also has the potential for moderate
    long-term total return as a result of its stake in equity securities.

*   Strategic  Allocation:  Moderate  seeks  long-term  capital growth with some
    regular  income.  It  emphasizes  investments  in  equity  securities,   but
    maintains a sizeable stake in bonds and money market securities.

*   Strategic Allocation: Aggressive seeks long-term capital growth with a small
    amount of  income.  It  emphasizes  investments  in equity  securities,  but
    maintains a portion of its assets in bonds and money market securities.

   
You should be aware that the names of the three asset  allocation  funds offered
in this  Prospectus  are  intended  to reflect  the  relative  short-term  price
volatility  risk  among  the  funds and not as an  indication  of the  advisor's
assessment  of the  riskiness  of the funds as compared to other  mutual  funds,
including other mutual funds within the American Century family of funds.
    

How do the funds pursue their investment objectives?

The funds' strategic asset allocation  strategy  diversifies  investments  among
equity securities,  bonds and cash-equivalent  instruments. The funds may invest
in any type of U.S. or foreign  equity  security that meets certain  fundamental
and  technical   standards.   The  fund  advisor  draws  on  growth,  value  and
quantitative  investment techniques in managing the equity portion of the funds'
portfolios and diversifies the funds' equity investments among small, medium and
large companies.

   
The growth  strategy looks for companies with earnings and revenues that are not
only growing, but growing at a successively faster, or accelerating,  pace. This
strategy  is based on the  premise  that,  over the long  term,  the  stocks  of
companies with  accelerating  earnings and revenues have a  greater-than-average
chance to increase  in value.  The value  investment  discipline  seeks  capital
growth by investing in equity securities of well-established  companies that the
funds' managers believe to be temporarily undervalued.  The primary quantitative
management  technique the managers use is portfolio  optimization.  The managers
may   construct  a  portion  of  the  funds'   portfolios   to  match  the  risk
characteristics  of the S&P 500, and then optimize each portfolio to achieve the
desired  balance of risk and return  potential.  Although  the funds will remain
exposed to each of the investment  disciplines and categories described above, a
particular  discipline  or investment  category may be  emphasized  when, in the
managers'  opinion,  such  discipline  or  investment  category  is  undervalued
relative to the other disciplines or categories.

The funds also invest in a variety of debt  securities  payable in both U.S. and
foreign currencies.  The funds primarily invest in investment-grade  securities,
that is, securities rated in the four highest  categories by independent  rating
organizations.  However,  Strategic Allocation:  Moderate may invest up to 5% of
its assets,  and Strategic  Allocation:  Aggressive  may invest up to 10% of its
assets,  in  high-yield  securities.   High-yield  securities  are  higher-risk,
nonconvertible debt obligations that are rated below investment grade. The funds
may also invest in unrated  securities based on the funds' advisor's  assessment
of their credit quality. The maturities of fixed-income  securities in which the
funds invest are expected to range from two to 30 years.

(left margin)
(graphic of hand with index finger pointing)
Fixed-income  securities are rated by nationally  recognized  securities ratings
organizations  (SROs),  such as Moody's and Standard & Poor's.  Each SRO has its
own system for  classifying  securities,  but each tries to indicate a company's
ability  to  make  timely  payments  of  interest  and  principal.   A  detailed
description  of SRO's,  their ratings  system and what we do if a security isn't
rated is included in the Statement of Additional Information.

The  funds  may  invest  the cash  equivalent  portion  of their  portfolios  in
high-quality  money market  investments  (denominated in U.S. dollars or foreign
currencies).

The following  table shows the  operating  ranges in which each fund's asset mix
may vary over short-term periods.  These variations may be due to differences in
asset class performance or prevailing market conditions.

- --------------------------------------------------------------------------------
Strategic Allocation:
Moderate                50-70%                    20-40%            5-20%

What are the primary risks of investing in the fund?

The value of the funds'  shares  depends on the value of the  stocks,  bonds and
other  securities  they own. The value of the individual  equity  securities the
funds own will go up and down depending on the performance of the companies that
issued them, general market and economic conditions, and investor confidence.

The value of the funds' fixed income  securities  will be affected  primarily by
rising or falling  interest  rates and the  continued  ability of the issuers of
these securities to make payments of interest and principal as they become due.

   
When interest  rates  change,  the amount of income the fund  generates  will be
affected.  Generally,  when interest rates rise, the funds' income and its share
value will decline. The opposite is true when interest rates decline.

The  lowest-rated  investment-grade  bonds in which the funds may invest contain
some speculative  characteristics.  Having those bonds in the funds'  portfolios
means the  funds'  value may go down more if  interest  rates or other  economic
conditions  change  than if the funds  contained  only  higher-rated  bonds.  In
addition,  Strategic Allocation:  Moderate and Strategic Allocation:  Aggressive
may invest in higher-risk high-yield  securities,  sometimes referred to as junk
bonds.  These securities are considered to be predominantly  speculative and are
more likely to be  negatively  affected  by changes in  interest  rates or other
economic conditions.
    

As with all funds,  at any given time, the value of your shares of the funds may
be worth more or less than the price you paid.  If you sell your shares when the
value is less than the price you paid, you will lose money.

Although  the  fund  advisor  invests  the  funds'  assets   primarily  in  U.S.
securities,  the funds can invest in  securities of foreign  companies.  Foreign
securities can have certain  unique risks,  including  fluctuations  in currency
exchange rates, unstable political and economic structures, reduced availability
of public information and the lack of uniform financial reporting and regulatory
practices  similar to those  that  apply to U.S.  issuers.  These  factors  make
investing  in  foreign  securities  generally  riskier  than  investing  in U.S.
securities.  To the extent the funds invest in foreign  securities,  the overall
risk of the funds could be affected.

   
These funds are intended for investors who seek to diversify  their assets among
various  classes  of  investments,  such  as  stocks,  bonds  and  money  market
instruments,  and who are willing to accept the risks associated with the funds'
investment strategies.

Management

Who manages the funds?

The Board of Directors,  investment  advisor and fund  management  team play key
roles in the management of the funds.

The Board of Directors

   
The Board of Directors  oversees the  management of the funds and meets at least
quarterly  to  review  reports  about  fund  operations.  Although  the Board of
Directors  does not manage the funds,  it has hired an investment  advisor to do
so. More than two-thirds of the Directors are independent of the funds' advisor;
that is, they are not employed by and have no financial interest in the advisor.
    

The Investment Advisor

The funds' investment  advisor is American Century Investment  Management,  Inc.
The advisor has been  managing  mutual  funds  since 1958.  American  Century is
headquartered at 4500 Main Street, Kansas City, Missouri 64111.

The advisor is responsible  for managing the investment  portfolios of the funds
and directing the purchase and sale of their investment securities.  The advisor
also arranges for transfer agency,  custody and all other services necessary for
the funds to operate.

For the services it provided to the funds during their most recent  fiscal year,
the  advisor  received a unified  management  fee based on a  percentage  of the
average  net assets of the Advisor  Class of shares of each fund.  The amount of
the  management  fee is  calculated  on a  class-by-class  basis  daily and paid
monthly.

   
Out of that fee, the advisor paid all  expenses of managing  and  operating  the
funds  except  brokerage  expenses,  taxes,  interest,  fees and expenses of the
independent directors (including legal counsel fees) and extraordinary expenses.
A  portion  of  the  management  fee  may  be  paid  by the  funds'  advisor  to
unaffiliated  third  parties who  provide  record-  keeping  and  administrative
services that would otherwise be performed by an affiliate of the advisor.

American  Century has a Code of Ethics  designed to ensure that the interests of
fund  shareholders  come before the interests of the people who manage the fund.
Among other  provisions,  the Code of Ethics  prohibits  portfolio  managers and

or from  profiting  from the  purchase and sale of the same  security  within 60

securities by the funds to obtain approval before executing  permitted  personal
trades.

Fundamental Investment Policies

Fundamental  investment  policies  contained  in  the  Statement  of  Additional
Information  and the  investment  objectives  of the  funds  may not be  changed
without a shareholder vote. The Board of Directors may change any other policies
and investment strategies.

Year 2000 Issues

Many of the world's  computer  systems  currently  cannot properly  recognize or
process date-sensitive information relating to the Year 2000 and beyond. Because
this may impact the computer systems of various American  Century-affiliated and
external service providers for the funds,  American Century formally initiated a
Year 2000  readiness  project in July 1997.  It  involves a team of  information
technology  professionals  assisted  by  outside  consultants  and  guided  by a
senior-level steering committee.  The team's goal is to assess the impact of the
Year 2000 on  American  Century's  systems,  renovate  or  replace  noncompliant
critical systems and test those systems. In addition,  the team has been working
to gather  information  about the Year 2000  efforts of the funds'  other  major
service providers.

Although  American Century believes its critical systems will function  properly
in the Year 2000, this is not guaranteed.  If the efforts of American Century or
its  external  service  providers  are  not  successful,  the  funds'  business,
particularly the provision of shareholder services, may be hampered.

   
In  addition,  the  issuers  of  securities  the funds own could  have Year 2000
computer problems. Foreign issuers, especially those in emerging markets, may be
more  susceptible  to such  problems than U.S.  issuers.  These  problems  could
negatively affect the value of issuers' securities, which, in turn, could impact
the funds' performance. The advisor has established a process to gather publicly
available  information about the Year 2000 readiness of these issuers.  However,
this  process may not  uncover all  relevant  information,  and the  information
gathered  may not be complete  and  accurate.  Moreover,  an issuer's  Year 2000
readiness is only one of many factors the fund managers may consider when making
investment decisions, and other factors may receive greater weight.

Investing with American Century

Eligibility for Advisor Class Shares

The  Advisor  Class  shares  are  intended  for  purchase  by   participants  in
employer-sponsored retirement or savings plans and for persons purchasing shares
through   broker-dealers,   banks,  insurance  companies  and  other  "financial
intermediaries" that provide various administrative and distribution services.

Investing Through Financial Intermediaries

If you do business  with us through a  financial  intermediary  or a  retirement
plan,  your ability to purchase,  exchange and redeem  shares will depend on the
policies of that entity. Some policy differences may include

* minimum investment requirements

* exchange policies

* fund choices

   
* cutoff time for investments
    

Please  contact  your  financial  intermediary  or plan  sponsor  for a complete
description  of its policies.  Copies of the funds' annual  reports,  semiannual
reports  and  Statements  of  Additional  Information  are  available  from your
intermediary or plan sponsor.

Certain  financial  intermediaries  perform for their clients  recordkeeping and
administrative  services that would otherwise be performed by American Century's
transfer agent.  In some  circumstances,  American  Century will pay the service
provider a fee for performing those services.

Although  transactions in fund shares may be made directly with American Century
at no charge,  you also may purchase,  redeem and exchange  fund shares  through
financial  intermediaries that charge a transaction-based or other fee for their
services. Those charges are retained by the intermediary and are not shared with
American Century or the funds.

   
American Century has contracts with certain financial  intermediaries  requiring
them to track  the time  investment  orders  are  received  and to  comply  with
procedures  relating to the  transmission  of orders.  The funds have authorized
those  intermediaries  to accept  orders on their behalf up to the time at which
the net asset value is determined.  If those orders are  transmitted to American
Century and paid for in accordance with the contract, they will be priced at the
net asset value next  determined  after your  request is received in in the form
required by the intermediary on a fund's behalf.

(left margin)
(graphic of hand with index finger pointing)
Financial intermediaries include banks, broker-dealers,  insurance companies and
investment advisors.

Abusive Trading Practices

We do not permit market-timing or other abusive trading practices in our funds.

Excessive,  short-term  (market-timing)  or other abusive trading  practices may
disrupt portfolio management  strategies and harm fund performance.  To minimize
harm to the funds and their  shareholders,  we  reserve  the right to reject any
purchase order (including  exchanges) from any investor we believe has a history
of  abusive  trading  or  whose  trading,  in our  judgment,  has been or may be
disruptive to a fund. In making this judgment,  we may consider  trading done in
multiple  accounts under common ownership or control.  We also reserve the right
to delay  delivery of your  redemption  proceeds--up  to seven days--or to honor
certain redemptions with securities,  rather than cash, as described in the next
section.

Special Requirements for Large Redemptions

If,  during any 90-day  period,  you redeem fund shares worth more than $250,000
(or 1% of the assets of the fund if that percentage is less than  $250,000),  we
reserve  the right to pay part or all of the  redemption  proceeds  in excess of
this amount in readily marketable securities instead of cash. If we make payment
in securities,  we will value the securities,  selected by the fund, in the same
manner as we do in computing  the fund's net asset value.  We may provide  these
securities in lieu of cash without prior notice.

If your  redemption  would  exceed  this limit and you would like to avoid being
paid in  securities,  please  provide us with an  unconditional  instruction  to
redeem at least 15 days prior to the date on which the redemption transaction is
to occur.  The instruction must specify the dollar amount or number of shares to
be redeemed and the date of the  transaction.  This  minimizes the effect of the
redemption on the fund and its remaining shareholders.

Share Price and Distributions

Share Price

   
American  Century  determines  the net asset  value (NAV) of the funds as of the
close of regular trading on the New York Stock Exchange  (usually 4 p.m. Eastern
time) each day the Exchange is open.  On days when the Exchange is not open,  we
do not  calculate  the NAV. The NAV of a fund share is the current  value of the
fund's  assets,  minus any  liabilities,  divided by the  number of fund  shares
outstanding.

If  current  market  prices  of  securities  owned  by a fund  are  not  readily
available,  the  advisor  may  determine  their  fair value in  accordance  with
procedures  adopted by the fund's Board of  Directors.  Trading of securities in
foreign  markets  may not take place on every day the  Exchange  is open.  Also,
trading in some foreign  markets may take place on weekends or holidays when the
fund's  NAV is not  calculated.  So, the value of the  fund's  portfolio  may be
affected on days when you can't purchase or redeem shares of the fund.

We will price your purchase,  exchange or redemption at the NAV next  determined
after we receive your transaction request in good order.

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  cutoff  time for  receiving  orders and to make
payment for any purchase  transactions in accordance with the funds'  procedures
or any  contractual  arrangements  with the funds or the funds'  distributor  in
order for you to receive that day's price.
    

Distributions

Federal tax laws require each fund to make  distributions to its shareholders in
order  to  qualify  as a  "regulated  investment  company."  Qualification  as a
regulated  investment  company means that the funds will not be subject to state
or federal  income  tax on  amounts  distributed.  The  distributions  generally
consist of dividends and interest received, as well as capital gains realized on
the sale of investment securities.

   
The funds pay distributions of substantially all of their income quarterly, with
the exception of Strategic Allocation: Aggressive, which pays such distributions
annually.  Distributions  from  realized  capital  gains are paid  twice a year,
usually in March and  December.  They may make more frequent  distributions,  if
necessary, to comply with Internal Revenue Code Provisions. Distributions may be
taxable as ordinary  income,  capital gains or a combination of the two. Capital
gains are taxed at different rates depending on the length of time the fund held
the securities that were sold.  Distributions  are reinvested  automatically  in
additional shares unless you choose another option.

Participants in employer-sponsored retirement or savings plans must reinvest all
distributions.  For shareholders  investing  through taxable  accounts,  we will
reinvest  distributions unless you elect to receive them in cash. Please consult
your services guide for further  information  regarding  distributions  and your
distribution options.

(left margin)
The net asset value of the fund is the price of the fund's shares.

Capital gains are increases in value of a capital asset, such as stock, from the
time the assets are purchased. Tax becomes due on capital gains once an asset is
sold.
    


www.americancentury.com                   American Century Investments        13


Taxes

The tax  consequences  of  owning  shares of the funds  will vary  depending  on
whether you own them through a taxable or tax-deferred account. Tax consequences
result from  distributions  by a fund of  dividend  and  interest  income it has
received and capital gains it has generated  through its investment  activities,
and by sales of fund shares by investors after the net asset value has increased
or decreased.

Tax-Deferred Accounts

   
If you purchase fund shares through a tax-deferred  account, such as an IRA or a
qualified  employer-sponsored  retirement  or savings  plan,  income and capital
gains  distributions  usually will not be subject to current taxation,  but will
accumulate in your account  under the plan on a  tax-deferred  basis.  Likewise,
moving  from one fund to  another  fund  within a plan or  tax-deferred  account
generally  will  not  cause  you to be  taxed.  For  information  about  the tax
consequences of making  purchases or withdrawals  through an  employer-sponsored
retirement  or  savings  plan,  or  through  an IRA,  please  consult  your plan
administrator, your summary plan description or a professional tax advisor.

Taxable Accounts

If you own fund shares through a taxable account,  distributions by the fund and
sales by you of fund shares may cause you to be taxed.

Taxability of Distributions

Fund distributions may consist of income earned by the fund from sources such as
dividends  and  interest,  or  capital  gains  generated  from  the sale of fund
investments. Distributions of income are taxed as ordinary income. Distributions
of capital gains are classified  either as short-term or long-term and are taxed
as follows:
    

<TABLE>
Type of distribution      Tax rate for 15% bracket    Tax rate for 28% bracket or above
- ---------------------------------------------------------------------------------------
<S>                            <C>                              <C>
Short-term capital gains  Ordinary income rate        Ordinary income rate
- ---------------------------------------------------------------------------------------
</TABLE>
Long-term capital gains        10%                              20%

The tax status of any  distribution  of capital  gains is determined by how long
the fund held the  underlying  security that was sold,  not by how long you have
been  invested  in the  fund or  whether  you  reinvest  your  distributions  in
additional  shares or take them as income.  American Century will detail the tax
status of fund  distributions  for each calendar year in an annual tax statement
from the fund.

Distributions  also may be subject to state and local taxes.  Because everyone's
tax situation is unique,  always  consult your tax  professional  about federal,
state and local tax consequences.

   
Taxes on Transactions

Your  redemptions--including  exchanges  to other  American  Century  funds--are
subject to capital  gains tax.  The table above can provide a general  guide for
your potential tax liability when selling or exchanging fund shares.  Short-term
capital gains are gains on fund shares you held for 12 months or less. Long-term
capital gains are gains on fund shares you held for more than 12 months. If your
shares  decrease in value,  their sale or exchange will result in a long-term or
short-term capital loss.
    

(left margin)
(graphic of hand with index finger pointing) 
Buying a Dividend

Purchasing  fund shares in a taxable  account  shortly before a distribution  is
sometimes known as buying a dividend.  In taxable accounts,  you must pay income
taxes on the  distribution  whether you reinvest the  distribution or take it in
cash. In addition,  you will have to pay taxes on the  distribution  whether the
value of your  investment  decreased,  increased  or remained the same after you
bought the fund shares.

The risk in buying a dividend  is that a fund's  portfolio  may build up taxable
gains throughout the period covered by a distribution, as securities are sold at
a profit. We distribute those gains to you, after  subtracting any losses,  even
if you did not own the shares when the gains occurred.

If you buy a  dividend,  you incur the full tax  liability  of the  distribution
period,  but you may not enjoy the full  benefit  of the gains  realized  in the
fund's portfolio.

Multiple Class Information

American  Century  offers two classes of the funds:  Investor  Class and Advisor
Class.  The shares  offered by this  Prospectus are Advisor Class shares and are
offered primarily to institutional investors, through institutional distribution
channels,  such  as  employer-sponsored  retirement  plans,  or  through  banks,
broker-dealers and insurance companies.

   
American Century offers another class of shares that has no up-front or deferred
charges,  commissions  or 12b-1  fees.  The  other  class  has  different  fees,
expenses,  and/or minimum  investment  requirements  than the Advisor Class. The
difference  in the fee  structures  among  the  classes  is the  result of their
separate  arrangements  for  shareholder and  distribution  services and not the
result of any difference in amounts  charged by the advisor for core  investment
advisory  services.  Accordingly,  the core investment  advisory expenses do not
vary by  class.  Different  fees  and  expenses  will  affect  performance.  For
additional  information concerning the other class of shares not offered by this
Prospectus,  call us at 1-800-345-2021  for Investor class shares.  You can also
contact a sales  representative or financial  intermediary who offers that class
of shares.
    

Except as  described  below,  all  classes  of  shares of a fund have  identical
voting,  dividend,   liquidation  and  other  rights,  preferences,   terms  and
conditions.  The only  differences  among the various classes are (a) each class
may be subject to different  expenses specific to that class, (b) each class has
a different identifying designation or name, (c) each class has exclusive voting
rights with respect to matters solely  affecting such class,  and (d) each class
may have different exchange privileges.

Service and Distribution Fees

   
Investment Company Act Rule 12b-1 permits mutual funds that adopt a written plan
to pay out of fund assets certain  expenses  associated with the distribution of
their shares. The funds' Advisor Class shares have a 12b-1 Plan. Under the Plan,
each  fund  pays an  annual  fee of  0.50%  of fund  assets,  half  for  certain
shareholder and administrative  services and half for distribution services. The
advisor,  as paying  agent for the funds,  pays all or a portion of such fees to
the  banks,  broker-dealers  and  insurance  companies  that  make  such  shares
available.  Because  these fees are paid out of the funds'  assets on an ongoing
basis,  over time these fees will increase the cost of your  investment  and may
cost  you  more  than  paying  other  types of  sales  charges.  For  additional
information about the Plan and its terms, see "Multiple Class  Structure--Master
Distribution  and  Shareholder  Services  Plan" in the  Statement of  Additional
Information.

Financial Highlights

Understanding the Financial Highlights

The tables on the next few pages  itemize  what  contributed  to the  changes in
share  price  during the  period.  They also show the changes in share price for
this period in comparison to changes over the last three fiscal periods.

   
On a per-share basis, each table includes as appropriate
    

*  share price at the beginning of the period

*  investment income and capital gains or losses

*  distributions of income and capital gains paid to shareholders

*  share price at the end of the period

   
Each table also includes some key statistics for the period as appropriate

*  Total Return--the overall percentage of return of the fund, assuming the
   reinvestment of all distributions

*  Expense Ratio--operating expenses as a percentage of average net assets

*  Net Income Ratio--net investment income as a percentage of average net asset

*  Portfolio Turnover--the percentage of the fund's buying and selling activity

The Financial Highlights have been audited by Deloitte & Touche LLP, independent
auditors.  Their  Independent  Auditors' report is included in the funds' annual
reports for the year ended November 30, 1998, which is incorporated by reference
into the Statement of Additional Information, and is available upon request.

Performance Information of Other Class

The following  financial  information is provided to show the performance of the
funds' original class of shares.  This class,  the Investor  Class,  has a total
expense ratio that is 0.25% lower than the Advisor  Class.  If the Advisor Class
existed  during the periods  presented,  its  performance  would have been lower
because of the additional expense.

These tables  itemize what  contributed to the changes in share price during the
period, and compares this to changes over the last three fiscal periods.

On a per-share basis, each table includes as appropriate

*  share price at the beginning of the period

*  investment income and capital gains or losses

*  distributions of income and capital gains paid to shareholders

*  share price at the end of the period

Each table also includes some key statistics for the period as appropriate

*  Total Return--the overall percentage of return of the fund, assuming the
   reinvestment of all distributions

*  Expense Ratio--operating expenses as a percentage of average net assets

*  Net Income Ratio--net investment income as a percentage of average net asset

*  Portfolio Turnover--the percentage of the fund's buying and selling activity

The Financial Highlights have been audited by Deloitte & Touche LLP, independent
auditors.  Their  Independent  Auditors' report is included in the funds' annual
report for the year ended November 30, 1998,  which is incorporated by reference
into the Statement of Additional Information, and is available upon request.

 THE FUNDS' HISTORY

  American Century Strategic Asset Allocations, Inc. is a registered open-end
management investment company that was organized as a Maryland corporation on
April 4, 1994. Prior to January 1, 1997, it was known as Twentieth Century
Strategic Asset Allocations, Inc. Throughout this Statement of Additional
Information, we refer to American Century Strategic Asset Allocations as the
corporation.

  Each fund described in this Statement of Additional Information is a separate
series of the corporation and operates for many purposes as if it were an
independent company. Each fund has its own investment objective, strategy,
management team, assets, tax identification and stock registration number.

FUND INVESTMENT GUIDELINES

   
    This section explains the extent to which the funds' advisor, American
Century Investment Management, Inc., can use various investment  vehicles and
strategies in managing a fund's assets. Descriptions of the investment
techniques and risks associated with each appear in the section, "Investment
Strategies and Risks," which begins on page 5. In the case of the funds'
principal investment strategies, these descriptions elaborate upon discussions
contained in the Prospectus.
    

    Each fund is a diversified open-end investment company as defined in the
Investment Company Act of 1940 (the Investment Company Act). Diversified means
that, with respect to 75% of its total assets, each fund will not invest more
than 5% of its total assets in the securities of a single issuer.

    To meet federal tax requirements for qualification as a regulated investment
company, each fund must limit its investments so that at the close of each
quarter of its taxable year (1) no more than 25% of its total assets are
invested in the securities of a single issuer (other than the U.S government or
a regulated investment company), and (2) with respect to at least 50% of its
total assets, no more than 5% of its total assets are invested in the securities
of a single issuer.

    In general, within the restrictions outlined here  and in the funds'
Prospectus, the advisor has broad powers to decide how to invest fund assets,
including the power to hold them uninvested.

    Investments are varied according to what is judged advantageous under
changing economic conditions. It is the advisor's policy to retain  maximum
flexibility in management without restrictive provisions as to the proportion of
one  or another class of securities that may be held, subject to the investment
restrictions described  in the funds' Prospectus and below.

    As described in the funds' Prospectus, each fund's assets are allocated
among major asset classes according to its respective asset mix and subject to
the applicable operating range. Each fund's assets are further diversified among
various investment categories and disciplines within the major asset classes.

    The equity portion of a fund's portfolio may be invested in any type of
domestic or foreign equity or equity equivalent security, primarily common
stocks, that meets certain fundamental and technical standards of selection.
Equity equivalents include securities that permit the fund to receive an equity
interest in an issuer, the opportunity to acquire an equity interest in an
issuer, or the opportunity to receive a return on its investment that permits
the fund to benefit from the growth over time in the equity of an issuer.
Examples of equity securities and equity equivalents include preferred stock,
convertible preferred stock and convertible debt securities. Equity equivalents
may also include securities whose value or return is derived from the value or
return of a different security. Depositary receipts, which are described


2                                                  American Century Investments


   
below under the heading "Foreign Securities," are  an example of the type
of derivative security in which the funds might invest. Derivative securities
are discussed in greater detail below under the heading "Derivative
Securities."
    

    The funds' managers utilize several investment disciplines in managing the
equity portion of each fund's portfolio, including growth, value and
quantitative management strategies. The growth  discipline seeks long-term
capital appreciation by investing in companies whose earnings and revenue trends
meet the advisor's standards of selection, which generally means that the
companies have demonstrated, or, in the managers' opinion, have the prospects
for demonstrating, accelerating earnings and revenues as compared to prior
period and/or industry competitors. The value investment discipline seeks
capital growth by investing in equity securities of well-established companies
that the managers believe to be temporarily undervalued.

    The advisor believes that both value investing and growth investing provide
the potential for appreciation over time. Value investing tends to provide less
volatile results. This lower volatility means that the price of value stocks
tends not to fall as significantly as the price of growth stocks in down
markets. However, value stocks do not usually appreciate as significantly as
growth stocks do in up markets. In keeping with the diversification theme of
these funds, and as a result of management's belief that these styles are
complementary, both disciplines will be represented to some degree in each
portfolio at all times.

    As noted, the value investment discipline tends to be less volatile than the
growth style. As a result, Strategic Allocation: Conservative will generally
have a higher proportion of its equity investments in value stocks than the
other two funds. Likewise, Strategic Allocation: Aggressive will generally have
a greater proportion of growth stocks than either Strategic Allocation: Moderate
or Strategic Allocation: Conservative.

    In addition, the equity portion of each fund's portfolio will be further
diversified among small, medium and large companies. This approach provides
investors with an additional level of diversification and enables investors to
achieve a broader exposure to the various capitalization ranges without having
to invest in multiple funds.

    The funds' managers may also apply quantitative management techniques to a
portion of each fund's portfolio. These techniques combine elements of both
growth and value investing and are intended to reduce overall volatility
relative to the market. Quantitative management combines two investment
management approaches. The first is active management, which allows the managers
to select investments for a fund without reference to an index or investment
model. The second is indexing, in which the managers try to match a portion of a
fund's portfolio composition to that of a particular index.

    The primary quantitative management technique the managers use is portfolio
optimization. The managers construct a portion of the funds' portfolios to match
the risk characteristics of the S&P 500 and then optimize each portfolio to
achieve the desired balance of risk and return potential.

   
    Although the funds will remain exposed to each of the investment disciplines
and categories described above, a particular discipline or investment category
may be emphasized when, in the managers' opinion, such discipline or investment
category is undervalued relative to the other disciplines or categories.
    

    The fixed income portion of a fund's portfolio will include U.S. Treasury
securities, securities issued or guaranteed by the U.S. government or a foreign
government, or an agency or instrumentality of the U.S. or a foreign government,
and nonconvertible debt obligations issued by U.S. or foreign corporations. The
funds may also invest in mortgage-related and other asset-backed securities,
which are described in greater detail under the heading "Mortgage-Related and
Other Asset-Backed Securities."  As with the equity portion of a fund's
portfolio, the bond portion of a fund's portfolio will be diversified among the
various types of fixed income investment categories described above. The
managers' strategy is to actively manage the portfolio by investing the fund's
assets in sectors they believe are undervalued (relative to the other sectors)
and that represent better relative long-term investment opportunities.

    The value of fixed income securities fluctuates based on changes in interest
rates and in the credit quality of the issuer. Debt securities that comprise


Statement of Additional Information                                           3


   
part of a fund's fixed income portfolio will primarily be limited to
investment-grade obligations. However, Strategic Allocation: Moderate may invest
up to 5%  of its assets, and Strategic Allocation: Aggressive  may invest up to
10% of its assets, in "high yield" securities. Investment-grade means that at
the time  of purchase, such obligations are rated within the  four highest
categories by a nationally recognized  statistical rating organization [for
example, at least Baa by Moody's Investors Service, Inc. ("Moody's") or BBB by
Standard & Poor's Corporation ("S&P"), or, if  not rated, are of equivalent
investment quality as determined by the managers. According to Moody's, bonds
rated Baa are medium-grade and possess  some speculative characteristics. A BBB
rating by S&P indicates S&P's belief that a security exhibits a satisfactory
degree of safety and capacity for  repayment, but is more vulnerable to adverse
economic conditions and changing circumstances.

    High-yield securities, sometimes referred to as "junk bonds," are
higher-risk, nonconvertible  debt obligations that are rated below
investment-grade securities, or are unrated, but with similar credit quality.

    There are no credit or maturity restrictions on the fixed income securities
in which the high-yield  portion of a fund's portfolio may be invested. Debt
securities rated lower than Baa by Moody's or BBB by S&P or their equivalent are
considered by many to be predominantly speculative. Changes in economic
conditions or other circumstances are more likely to lead to a weakened capacity
to make principal and interest payments on such securities than is the case with
higher-quality debt securities. Regardless of  rating levels, all debt
securities considered for  purchase by the fund are analyzed by the managers to
determine, to the extent reasonably possible, that the planned investment is
consistent with the investment objective of the fund.

    Under normal market conditions, the maturities of fixed income securities in
which the funds invest will range from two to 30 years.
    

    The cash equivalent portion of a fund's  portfolio may be invested in
high-quality money  market instruments (denominated in U.S. dollars  or foreign
currencies), including U.S. government obligations, obligations of domestic and
foreign  banks, short-term corporate debt instruments and repurchase
agreements.

   
    Within each asset class, each fund's holdings will be invested across
industry groups and issuers that meet its investment criteria. This diversity of
investment is intended to help reduce the risk created by overconcentration in a
particular industry or issuer.

    The funds are "strategic" rather than "tactical"  allocation funds, which
means that the managers do not try to time the market to identify the exact time
when a major reallocation should be made. Instead, the managers utilize a
longer-term approach in  pursuing the funds' investment objectives, and  thus
select a blend of investments in the various  asset classes.
    

    The managers regularly review each fund's  investments and allocations and
may make changes in the securities holdings within each asset class or to a
fund's asset mix (within the defined operating ranges) to favor investments that
they believe will  provide the most favorable outlook for achieving a fund's
objective. Recommended reallocations may be implemented promptly or may be
implemented  gradually. In order to minimize the impact of reallocations on a
fund's performance, the managers will  generally attempt to reallocate assets
gradually.

    In determining the allocation of assets among U.S. and foreign capital
markets, the managers consider the condition and growth potential of the various
economies; the relative valuations of the markets; and social, political, and
economic factors that may affect the markets.

    In selecting securities in foreign currencies, the managers consider, among
other factors, the impact of foreign exchange rates relative to the U.S. dollar
value of such securities. The managers may seek to hedge all or a part of a
fund's foreign currency exposure through the use of forward foreign currency
contracts or options thereon.

   
    The funds attempt to diversify across asset classes and investment
categories to a greater extent than mutual funds that invest primarily in equity
securities or primarily in fixed income securities. However, the funds are
designed to fit three general risk profiles and may not provide an appropriately
balanced investment plan for all investors.

DETAILED INFORMATION ABOUT THE FUNDS

INVESTMENT STRATEGIES AND RISKS

    In addition to investing in common stocks, bonds and cash equivalent
instruments, the funds' managers may also use the various investment vehicles
and techniques described in this section in managing the funds' assets. This
section also details the risks  associated with each, because each technique
contributes to a fund's overall risk profile.

FOREIGN SECURITIES

   
    Each fund may invest in the securities (including debt securities) of
foreign issuers, including foreign governments and their agencies, when these
securities meet its standards of selection. Securities  of foreign issuers may
trade in the U.S. or foreign securities markets.
    

    The chart below shows the portion of each fund's total assets that may be
invested in the securities of foreign issuers.

                                                PERCENTAGE GENERALLY
FUND                                        INVESTED IN FOREIGN SECURITIES
- ------------------------------------------------------------------------
Strategic Allocation:
Conservative                                             7-17%
- ------------------------------------------------------------------------
Strategic Allocation:
Moderate                                                 10-30%
- ------------------------------------------------------------------------
Strategic Allocation:
Aggressive                                               15-35%
- ------------------------------------------------------------------------

   
    The funds may make such investments either directly in foreign securities or
indirectly by  purchasing depositary receipts or depositary shares of similar
instruments ("depositary receipts") for foreign securities. Depositary receipts
are securities that are listed on exchanges or quoted in the domestic
over-the-counter markets in one country but represent shares of issuers
domiciled in another country. Direct investments in foreign securities may be
made either on foreign securities exchanges or in the over-the-counter markets.
    

    Subject to its investment objective and policies, each fund may invest in
common stocks, convertible securities, preferred stocks, bonds, notes and other
debt securities of foreign issuers and debt securities of foreign governments
and their agencies. The credit quality standards applicable to domestic debt
securities purchased by each fund are also applicable to its foreign securities
investments. The funds will limit their purchase of debt securities to
investment-grade obligations.

    Investments in foreign securities may present certain risks, including:

   
    Currency Risk. The value of the foreign investments held by the funds may be
significantly affected by changes in currency exchange rates. The dollar value
of a foreign security generally decreases when the value of the dollar rises
against the foreign currency in which the security is denominated and tends to
increase when the value of the dollar falls against such currency. In addition,
the value of fund assets may be affected by losses and other expenses incurred
in converting between various currencies in order to purchase and sell foreign
securities and by currency restrictions, exchange control regulation, currency
devaluations and political developments.

    Political and Economic Risk. The economies of many of the countries in which
the funds may invest are not as developed as the economy of the United States
and may be subject to significantly different forces. Political or social
instability, expropriation, nationalization, or confiscatory taxation, and
limitations on the removal of funds or other assets, could also adversely affect
the value of investments. Further, the funds may encounter difficulties or be
unable to enforce ownership rights, pursue legal remedies or obtain judgments in
foreign courts.

    Regulatory Risk. Foreign companies generally are not subject to the
regulatory controls imposed on U.S. issuers and, in general, there is less
publicly available information about foreign securities than is available about
domestic securities. Many foreign companies are not subject to uniform
accounting, auditing and financial reporting standards, practices and
requirements comparable to those applicable to domestic companies. Income from
foreign securities owned by the funds may be reduced by a withholding tax at the
source, which would reduce dividend income payable to shareholders.

    Market and Trading Risk. Brokerage commission rates in foreign countries,
which are generally fixed rather than subject to negotiation as in the United
States, are likely to be higher. The securities markets in
    


Statement of Additional Information                                          5


   
many of the countries in which the funds may invest will have substantially
less trading volume than the principal U.S. markets. As a result, the securities
of some companies in these countries may be less liquid and more volatile than
comparable U.S. securities. Furthermore, one securities broker may represent
all or a significant part of the trading volume in a  particular country,
resulting in higher trading costs and decreased liquidity due to a lack of
alternative trading partners. There is generally less government regulation and
supervision of foreign stock exchanges, brokers and issuers, which may make it
difficult to enforce contractual obligations.

    Clearance and Settlement Risk. Foreign securities markets also have
different clearance and settlement procedures, and in certain markets there have
been times when settlements have been unable to keep pace with the volume of
securities transactions, making it difficult to conduct such transactions.
Delays in clearance and settlement could result in temporary periods when assets
of the funds are uninvested and no return is earned thereon. The inability of
the funds to make intended security purchases due to clearance and settlement
problems could cause the funds to miss attractive investment opportunities.
Inability to dispose of portfolio securities due to clearance and settlement
problems could result either in losses to the funds due to subsequent declines
in the value of the portfolio security or, if the fund has entered into a
contract to sell the security, liability to the purchaser.

    Ownership Risk. Evidence of securities ownership may be uncertain in many
foreign countries. In many of these countries, the most notable of which is the
Russian Federation, the ultimate evidence of securities ownership is the share
register held by the issuing company or its registrar. While some companies may
issue share certificates or provide extracts of the company's share register,
these are not negotiable instruments and are not effective evidence of
securities ownership. In an ownership dispute, the company's share register is
controlling. As a result, there is a risk that a fund's trade details could be
incorrectly or fraudulently entered on the issuer's share register at the time
of the transaction, or that a fund's ownership position could thereafter be
altered or deleted entirely, resulting in a loss to the fund. Each fund may
purchase and sell foreign currency on a spot basis and may engage in forward
currency contracts, currency options and futures transactions for hedging or any
other lawful purpose.  (See Derivative Securities on page 9.)

INVESTING IN EMERGING MARKET COUNTRIES

    Strategic Allocation: Moderate and Strategic Allocation: Aggressive may
invest a minority portion of their international holdings in securities of
issuers in emerging market (developing) countries. The funds consider "emerging
market countries" to include all countries that are considered by the advisor to
be developing or emerging countries. Currently, the countries not included in
this category for the funds are the United States, Canada, Japan, the United
Kingdom, Germany, Austria, France, Hong Kong, Italy, Ireland, Singapore, Spain,
Belgium, the Netherlands, Portugal, Switzerland, Sweden, Finland, Norway,
Denmark, Australia and New Zealand. In addition, as used in this Statement of
Additional Information, "securities of issuers in emerging market countries"
means (i) securities of issuers the principal securities trading market for
which is an emerging market country or (ii) securities of issuers having their
principal place of business or principal office in an emerging market country.
    

    Investing in securities of issuers in emerging market countries involves
exposure to significantly higher risk than investing in countries with developed
markets. Emerging market countries may have economic structures that are
generally less diverse and mature, and political systems that can be expected to
be less stable than those of developed countries.  Securities prices in emerging
market countries can be significantly more volatile than in developed countries,
reflecting the greater uncertainties of investing in lesser developed markets
and economies. In particular, emerging market countries may have relatively
unstable governments, and may present the risk of nationalization of businesses,
expropriation, confiscatory taxation or in certain instances, reversion to
closed-market, centrally planned economies. Such countries may also have less
protection of property rights than developed countries.

    The economies of emerging market countries may


6                                               American Century Investments


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

   
MORTGAGE-RELATED AND OTHER ASSET-BACKED SECURITIES

    The funds may purchase mortgage-related and other asset-backed securities.
Mortgage pass- through securities are securities representing  interests in
"pools" of mortgages in which payments of both interest and principal on the
securities are generally made monthly, in effect "passing through" monthly
payments made by the individual borrowers on the residential mortgage loans that
underlie the securities (net of fees paid to the issuer or guarantor of the
securities).
    

    Early repayment of principal on mortgage  pass-through securities (arising
from prepayments of principal due to sale of the underlying property,
refinancing, or foreclosure, net of fees and costs which may be incurred) may
expose the funds to a lower rate of return upon reinvestment of principal. Also,
if a security subject to prepayment were purchased at a premium, in the event of
prepayment, the value of the premium would be lost. Like other  fixed-income
securities, when interest rates rise, the value of a mortgage-related security
generally will decline; however, when interest rates decline, the value of
mortgage-related securities with prepayment features may not increase as much as
other fixed-income securities.

    Payment of principal and interest on some  mortgage pass-through securities
(but not the market value of the securities themselves) may be guaranteed by the
full faith and credit of the U.S. government, as in the case of securities
guaranteed by the Government National Mortgage Association (GNMA), or guaranteed
by agencies or instrumentalities of  the U.S. government, as in the case of
securities  guaranteed by the Federal National Mortgage Association (FNMA) or
the Federal Home Loan Mortgage Corporation (FHLMC), which are supported only by
the discretionary authority of the U.S. government to purchase the agency's
obligations.

   
    Mortgage pass-through securities created by  nongovernmental issuers (such
as commercial banks, savings and loan institutions, private mortgage  insurance
companies, mortgage bankers and other secondary market issuers) may be supported
by  various forms of insurance or guarantees, including individual loan, title,
pool and hazard insurance and letters of credit, which may be issued by
governmental entities, private insurers, or the mortgage poolers.
    

    The funds may also invest in collateralized mortgage obligations (CMOs).
CMOs are mortgage-backed securities issued by government agencies;
single-purpose, stand-alone financial subsidiaries; trusts established by
financial institutions; or similar institutions. The funds may buy CMOs that:

*   are collateralized by pools of mortgages in which payment of principal and
    interest of each mortgage is guaranteed by an agency or instrumentality of
    the U.S. government;

*   are collateralized by pools of mortgages in which payment of principal and
    interest are guaranteed by the issuer, and the guarantee is collateralized
    by U.S. government securities; and

*   are securities in which the proceeds of the issue are invested in mortgage
    securities and payments of principal and interest are supported by the
    credit of an agency or instrumentality of the U.S. government.

FORWARD CURRENCY EXCHANGE CONTRACTS

   
    Each fund may purchase and sell foreign currency on a spot (i.e. cash) basis
and may engage in forward currency contracts, currency options and futures
transactions for hedging or any other lawful purpose. See "Derivative
Securities," page 9.
    

    The funds expect to use forward contracts under two circumstances:

   
(1) When a fund's managers wish to lock in the U.S. dollar price of a security
    when the fund
    


Statement of Additional Information                                            7


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

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

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

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

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

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

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

CONVERTIBLE SECURITIES

   
    A convertible security is a fixed-income security that offers the potential
for capital appreciation through a conversion feature that enables the holder to
convert the fixed-income security into a stated number of shares of common
stock. As fixed income securities, convertible securities provide a stable
stream of income, with generally higher yields than common stocks. Because
convertible securities offer the potential to benefit from increases in the
market price of the underlying common stock, however, they generally offer lower
yields than nonconvertible securities of similar quality. Of course, like all
fixed- income securities, there can be no assurance of  current income because
the issuers of the convertible
    


8                                                  AMERICAN CENTURY INVESTMENTS


securities may default on their obligations. In  addition, there can be no
assurance of capital  appreciation because the value of the underlying common
stock will fluctuate.

   
    Convertible securities generally are subordinated to other similar but
nonconvertible securities of the same issuer, although convertible bonds, as
corporate debt obligations, enjoy seniority in right of payment to all equity
securities, and convertible preferred stock is senior to common stock of the
same issuer. Because of the subordination feature, however, convertible
securities typically have lower ratings than similar nonconvertible securities.

    Unlike a convertible security that is a single  security, a synthetic
convertible security is comprised of two distinct securities that together
resemble  convertible securities in certain respects. Synthetic convertible
securities are created by combining  nonconvertible bonds or preferred stocks
with  warrants or stock call options. The options that will form elements of
synthetic convertible securities will be listed on a securities exchange or on
the National Association of Securities Dealers Automated Quotation Systems. The
two components of a  synthetic convertible security, which will be issued with
respect to the same entity, generally are not offered as a unit, and may be
purchased and sold by the fund at different times. Synthetic convertible
securities differ from convertible securities in certain respects, including
that each component of a synthetic convertible security has a separate market
value and responds differently to market fluctuations. Investing in synthetic
convertible securities involves the risk normally found in holding the
securities  comprising the synthetic convertible security.

    Each fund will limit its holdings of convertible debt securities to those
that, at the time of purchase, are rated at least B- by S&P or B3 by Moody's,
or, if not rated by S&P or Moody's, are of equivalent  investment quality as
determined by the fund's  managers. A fund's investments in convertible debt
securities and other high-yield, nonconvertible debt securities rated below
investment grade will comprise less than 35% of the fund's net assets.
    

SHORT SALES

    A fund may engage in short sales if, at the time of the short sale, the fund
owns or has the right to acquire securities equivalent in kind and amount to the
securities being sold short.

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

    A fund may make a short sale, as described above, when it wants to sell the
security it owns at a current attractive price, but also wishes to defer
recognition of gain or loss for federal income tax purposes. There will be
certain additional transaction costs associated with short sales, but the fund
will endeavor to offset these costs with income from the investment of the cash
proceeds of short sales.

   
PORTFOLIO LENDING
    

    In order to realize additional income, a fund  may lend its portfolio
securities. Such loans may  not exceed one-third of the fund's net assets valued
at market except (i) through the purchase of debt securities in accordance with
its investment objective, policies and limitations, or (ii) by engaging in
repurchase agreements with respect to portfolio securities.

DERIVATIVE SECURITIES

   
    To the extent permitted by its investment  objectives and policies, each of
the funds may  invest in securities that are commonly referred to  as derivative
securities. Generally, a derivative is a financial arrangement the value of
which is based  on, or derived from, a traditional security, asset, or market
index. Certain derivative securities are more accurately described as
index/structured securities. Index/structured securities are derivative
securities
    


Statement of Additional Information                                            9


   
whose value or performance is linked to other equity securities (such as
depositary receipts), currencies, interest rates, indices or other financial
indicators  (reference indices).

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

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

   
    No fund may invest in a derivative security unless the reference index or
the instrument to which it relates is an eligible investment for the fund. For
example, a security whose underlying value is linked to the price of oil would
not be a permissible investment because the funds may not invest in oil and gas
leases or futures.
    

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

    There is a range of risks associated with derivative investments, including

   
*   the risk that the underlying security, interest rate, market index or other
    financial asset will not move in the direction the fund managers anticipate;
    

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

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

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

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

INVESTMENTS IN COMPANIES WITH  
LIMITED OPERATING HISTORIES

    The funds may invest in the securities of issuers with limited operating
histories. The managers  consider an issuer to have a limited operating history
if that issuer has a record of less than three years of continuous operation.
The managers will consider  periods of capital formation, incubation,
consolidations, and research and development in determining whether a particular
issuer has a record of three years of continuous operation.
    

    Investments in securities of issuers with limited operating histories may
involve greater risks than investments in securities of more mature issuers.  By
their nature, such issuers present limited  operating history and financial
information upon which the manager may base its investment decision on behalf of
the funds. In addition, financial and other information regarding such issuers,
when  available, may be incomplete or inaccurate.

REPURCHASE AGREEMENTS

    Each 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 that 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 purchase 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.

   
    Because 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
    


10                                               American Century Investments


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 funds will limit repurchase agreement transactions to securities issued
by the U.S. government, its agencies and instrumentalities, and will enter into
such transactions with those banks and securities dealers who are deemed
creditworthy pursuant to  criteria adopted by the funds' Board of Directors.

VARIABLE- AND FLOATING-RATE OBLIGATIONS

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

OBLIGATIONS WITH TERM PUTS ATTACHED

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

   
    The managers expect that the funds will pay more for securities with puts
attached than for securities without these liquidity features.
    

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

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

WHEN-ISSUED AND FORWARD COMMITMENT AGREEMENTS

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

    When purchasing securities on a when-issued or forward commitment basis, a
fund assumes the rights and risks of ownership, including the risks of price and
yield fluctuations. Market rates of interest on debt securities at the time of
delivery may be higher or lower than those contracted for on the when-issued
security. Accordingly, the value of such security may decline prior to delivery,
which could result in a loss to the fund. While the fund will make commitments
to purchase or sell securities with the intention of actually receiving or
delivering them, it may sell the securities before the settlement date if doing
so is deemed advisable as a matter of investment strategy.

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


Statement of Additional Information                                          11


INVERSE FLOATERS

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

    Inverse floaters may be issued in conjunction with an equal amount of Dutch
Auction floating-rate bonds (floaters), or a market-based index may be used to
set the interest rate on these securities. A Dutch Auction is an auction system
in which the price of the security is gradually lowered until it meets a
responsive bid and is sold. Floaters and inverse floaters may be brought to
market by a broker-dealer who purchases fixed-rate bonds and places them in a
trust or by an issuer seeking to reduce interest expenses by using a
floater/inverse floater structure in lieu of fixed-rate bonds.

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

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

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

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

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

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

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

SHORT-TERM SECURITIES

   
    In order to meet anticipated redemptions, to hold pending the purchase of
additional securities for a funds portfolio, or in some cases, for temporary
defensive purposes, the funds may invest a portion of their assets in money
market and other short-term securities.
    

    Examples of those securities include

* Securities issued or guaranteed by the U.S. government and its agencies and
  instrumentalities;

* Commercial Paper;

* Certificates of Deposit and Euro Dollar Certificates of Deposit;

* Bankers' Acceptances;

   
* Short-term notes, bonds, debentures or other debt instruments; and
    

* Repurchase agreements.

   
OTHER INVESTMENT COMPANIES

     Each of the funds may invest up to 10% of its total assets in any other
mutual fund, including those of the advisor, provided that the investment is
consistent with the fund's investment policies and restrictions.
    


12                                                 American Century Investments


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

FUTURES AND OPTIONS

    Each fund may enter into futures contracts, options or options on futures
contracts. Funds may not, however, enter into a futures transaction for
speculative purposes. Generally, futures transactions will be used to

   
* protect against a decline in market value of the funds' securities (taking a
short futures position), or

* protect against the risk of an increase in market value for securities in
which the fund generally invests at a time when the fund is not fully invested
(taking a long futures position), or
    

* provide a temporary substitute for the purchase of an individual security that
may be purchased in an orderly fashion.

   
    Some futures and options strategies, such as  selling futures, buying puts
and writing calls, hedge a fund's investments against price fluctuations. Other
strategies, such as buying futures, writing puts and buying calls, tend to
increase market exposure. Although other techniques may be used to control a
fund's exposure to market fluctuations, the use of futures contracts may be a
more effective means of hedging this exposure. While a fund pays brokerage
commissions in connection with opening and closing out futures positions, these
costs are lower than the transaction costs incurred in the purchase and sale of
the underlying securities.

    For example, the sale of a future by a fund means the fund becomes obligated
to deliver the security (or securities, in the case of an index future) at a
specified price on a specified date. The purchase of a future means the fund
becomes obligated to buy the security (or securities) at a specified price on a
specified date. Futures contracts provide for the sale by one party and purchase
by another party of a specific security at a specified future time and price.
The funds may engage in futures and options transactions based on securities
indices that are consistent with the fund's investment objectives. Examples of
indices that may be used include the Bond Buyer Index of Municipal Bonds, for
fixed-income funds, or the S&P 500 Index, for equity funds. The funds also may
engage in futures and options transactions based on specific securities, such as
U.S. Treasury bonds or notes. Futures contracts are traded on national futures
exchanges. Futures exchanges and trading are regulated under the Commodity
Exchange Act by the Commodity Futures Trading Commission (CFTC), a U.S.
government agency.

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

    Unlike when the fund purchases or sells a bond, no price is paid or received
by the fund upon the  purchase or sale of the future. Initially, the fund will
be required to deposit an amount of cash or securities equal to a varying
specified percentage of the contract amount. This amount is known as initial
margin. The margin deposit is intended to assure completion of the contract
(delivery or acceptance of the underlying security) if it is not terminated
prior to the specified delivery date. They do not constitute margin
transactions for purposes of the funds' investment restrictions. Minimum initial
margin requirements are established by the futures exchanges and may be
    


Statement of Additional Information                                           13


   
revised. In addition, brokers may establish margin deposit requirements that
are higher than the exchange minimums. Cash held in the margin account is not
income-producing. Subsequent  payments, called variation margin, to and from the
broker, will be made on a daily basis as the price of the underlying debt
securities or index fluctuates, making the future more or less valuable , a
process known as marking the contract to market. Changes  in variation margin
are recorded by the fund as  unrealized gains or losses. At any time prior to
expiration of the future, the fund may elect to close the position by taking an
opposite position that will operate to terminate its position in the future. A
final determination of variation margin is then made;  additional cash is
required to be paid by or released to the fund and the fund realizes a loss or
gain.
    

RISKS RELATED TO FUTURES AND OPTIONS TRANSACTIONS

   
    Futures and options prices can be volatile, and trading in these markets
involves certain risks. If the fund managers apply a hedge at an inappropriate
time or judge interest rate or equity market trends incorrectly, futures and
options strategies may lower the fund's return.

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

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

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

OPTIONS ON FUTURES

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

    Although they do not currently intend to do so, the funds may write (or
sell) call options that obligate it to sell (or deliver) the option's underlying
instrument


14                                                 American Century Investments


upon exercise of the option. While the receipt of option premiums would
mitigate the effects of price declines, the funds would give up some ability to
participate in a price increase on the underlying security. If a fund were to
engage in options transactions, it would own the futures contract at the time a
call were written and would keep the contract open until the obligation to
deliver it pursuant to the call expired.

RESTRICTIONS ON THE USE OF CONTRACTS AND OPTIONS

    Each fund may enter into futures contracts, options or options on futures
contracts.

   
    Under the Commodity Exchange Act, a fund may enter into futures and options
transactions (a) for hedging purposes without regard to the percentage of assets
committed to initial margin and option premiums or (b) for other than hedging
purposes, provided that assets committed to initial margin and option premiums
do not exceed 5% of the fund's total assets. To the extent required by law, each
fund will  segregate cash or securities on its records in an amount sufficient
to cover its obligations under the futures contracts and options.
    

RESTRICTED AND ILLIQUID SECURITIES

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

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

    Since the secondary market for such securities is limited to certain
qualified institutional investors, the liquidity of such securities may be
limited accordingly and a fund may, from time to time, hold a Rule 144A or other
security that is illiquid. In such an event, the fund managers will consider
appropriate remedies to minimize the effect on such fund's liquidity.
    

ZERO-COUPON, STEP-COUPON AND PAY-IN-KIND SECURITIES

    Zero-coupon, step-coupon and pay-in-kind  securities are debt securities
that do not make  regular cash interest payments. Zero-coupon and step-coupon
securities are sold at a deep discount to their face value. Pay-in-kind
securities pay interest through the issuance of additional securities. Because
such securities do not pay current cash income, the price of these securities
can be volatile when interest rates fluctuate. While these securities do not pay
current cash income, federal income tax law requires the holders of zero-coupon,
step-coupon and pay-in-kind securities to include in income each year the
portion


STATEMENT OF ADDITIONAL INFORMATION                                           15


   
of the original issue discount and other noncash income on such securities
accrued during that year. In order to continue to qualify for treatment as a
regulated investment company under the Internal Revenue Code and avoid certain
excise tax, the funds may be required to dispose of other portfolio securities,
which may occur in periods of adverse market prices, in order to generate cash
to meet these  distribution requirements.

LOAN INTERESTS

    Loan interests are interests in amounts owed by a corporate, governmental or
other borrower to lenders or lending syndicates. Loan interests purchased by the
funds may have a maturity of any number of days or years, and may be acquired
from U.S. and foreign banks, insurance companies, finance companies or other
financial institutions that have made loans or are members of a lending
syndicate or from the holders of loan interests. Loan interests involve the risk
of loss in case of default or bankruptcy of the borrower and, in the case of
participation interests, involve a risk of insolvency of the agent lending bank
or other financial intermediary. Loan interests are not rated by any nationally
recognized securities rating organization and are, at present, not readily
marketable and may be subject to contractual restrictions on resale.
    

INVESTMENT POLICIES

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

FUNDAMENTAL INVESTMENT POLICIES

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

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

NONFUNDAMENTAL INVESTMENT POLICIES

    In addition, the funds are subject to the following additional investment
restrictions that are not fundamental and may be changed by the Board of
Directors.

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

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

Short Sales           A fund may not sell securities short, unless it owns or has the

                      short, and provided that transactions in futures contracts and options  are not
                      deemed to constitute selling securities short.

                       provided that margin payments in connection with futures contracts and options
                       on futures contracts shall not constitute purchasing securities on margin.

Futures & Options      A fund may enter into futures contracts, options or options
                       on futures contracts. Futures transactions may be used to (1) protect against a
                       decline in market value of the fund's securities, (2) protect against the risk
                       of an increase in market value for securities in which the fund generally
                       invests at a time when the fund is not fully-invested, or (3) provide a
                       temporary substitute for the purchase of an individual security that may be
                       purchased in an orderly fashion. A fund may not, however, enter into leveraged
                       futures transactions.
- ---------------------------------------------------------------------------------------------
Issuers with Limited   A fund may invest up to 5% of its assets in the securities of issuers with
                       limited operating histories. An Operating Histories issuer is considered to
                       have a limited operating history if that issuer has a record of less than
                       three years of continuous operation. Periods of capital formation,
                       incubation,  consolidations, and research and development may be
                       considered in determining whether a particular issuer has a record of three
                       years of continuous operation.
- ---------------------------------------------------------------------------------------------
</TABLE>
    

PORTFOLIO TURNOVER

   
    The portfolio turnover rates of the funds are shown in the Financial
Highlights tables in the Prospectus.
    

    With respect to each fund, the managers may purchase and sell securities
without regard to the length of time the security has been held. Accordingly,
the fund's rate of portfolio turnover may be substantial.

   
    The fund managers intend to purchase a given security whenever they believe
it will contribute to the stated objective of the fund. In order to achieve each
fund's investment objective, the managers may sell a given security, no matter
for how long or for how short a period it has been held in the portfolio, and no
matter whether the sale is at a gain or at a loss, if the managers believe that
the security is not fulfilling its purpose, either because, among other things,
it did not live up to the managers' expectations, or because it may be replaced
with another security holding greater promise, or because it has reached its
optimum potential, or because of a change in the circumstances of a particular
company or industry or in general economic conditions, or because of some
combination of such reasons.
    

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

   
    Because investment decisions are based on the anticipated contribution of
the security in question to a funds' objectives, the managers believe that the
rate of portfolio turnover is irrelevant when they believe a change is in order
to achieve those objectives. As a result, a fund's annual portfolio turnover
rate cannot be anticipated and may be higher than other mutual funds with
similar investment objectives. Higher turnover would generate correspondingly
greater  brokerage commissions, which is a cost the funds pay directly.
Portfolio turnover also may affect the character of capital gains realized and
distributed by the fund, if any, since short-term capital gains are taxable as
ordinary income. This disclosure regarding portfolio turnover is a statement of
fundamental policy and may be changed only by a vote of the shareholders.

    Because the managers do not take portfolio turnover rate into account in
making investment  decisions, (1) the managers have no intention of
    


18                                               American Century Investments


   
accomplishing any particular rate of portfolio turnover, whether high or low,
and (2) the portfolio turnover rates in the past should not be considered  as
representative of the rates that will be attained  in the future.
    

 MANAGEMENT

THE BOARD OF DIRECTORS

   
    The Board of Directors oversees the management of the funds and meets at
least quarterly to review reports about fund operations. Although the Board  of
Directors does not manage the funds, it has hired the advisor to do so.
Two-thirds of the directors are independent of the funds' advisor, that is, they
are not employed by and have no financial interest in the advisor.

    The individuals listed in the table below whose names are marked by an
asterisk (*) are interested persons of the funds (as defined in the Investment
Company Act) by virtue of, among other considerations, their affiliation with
either the advisor, American Century Investment Management, Inc. (ACIM); the
funds' agent for transfer and administrative services, American Century Services
Corporation (ACSC); the parent corporation of ACIM and ACSC, American Century
Companies, Inc. (ACC); ACC's subsidiaries; the funds' distribution agent and
co-administrator, Funds Distributor, Inc. (FDI); the funds or other funds
advised by the advisor. Each director listed below serves as a director of six
registered investment companies in the six investment companies served by this
board which are also advised by the advisor.

COMPENSATION OF DIRECTORS

    The directors also serve as directors for five American Century investment
companies other than American Century Strategic Asset Allocations, Inc. Each
director who is not an interested person as defined in the Investment Company
Act receives compensation for service as a member of the Board of all six such
companies based on a schedule that takes into account the number of meetings
attended and the assets of the funds for which the meetings are held. These fees
and expenses are divided among the six investment companies based, in part,
upon their relative net assets. Under the terms of the management agreement
with the advisor, the funds are responsible for paying such fees and expenses.

    The table presented shows the aggregate compensation paid by the corporation
for the periods indicated and by the six investment companies served by this
Board to each director who is not an interested person as defined in the
Investment Company Act.

(1)  Includes compensation paid to the directors during the fiscal year ended
November 30, 1998, and also includes amounts deferred at the election of the
directors under the American Century Mutual Funds Deferred Compensation Plan for
Non-Interested Directors and Trustees. The total amount of deferred compensation
included in the preceding table is as follows: Mr. Brown, $81.00; Ms. Hall, $
259.00; Mr. Hock, $75.00; Mr. Pratt, $179.00; Mr. Silver, $394.00 and Ms.
Strandjord, $510.00.

(2)  Includes compensation paid by the six investment company members of the
American Century family of funds served by this Board.
    

    The funds have adopted the American Century Deferred Compensation Plan for
Non-Interested Directors and Trustees. Under the plan, the independent directors
may defer receipt of all or any part of the fees to be paid to them for serving
as directors of the funds.

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

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

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

   
    No deferred fees were paid to any director under the plan during the fiscal
year ended November 30, 1998.

INVESTMENT ADVISOR

Century Investment Management, Inc. dated August 1, 1997. This agreement was
approved by the shareholders of each of the funds July 30, 1997. A description
of the responsibilities of the advisor appears in the Prospectus under the
heading "Management."
    

    For the services provided to the funds, the advisor receives a monthly fee
based on a percentage of the average net assets of the fund.

    For the services provided to the funds, the advisor receives a monthly fee

    On the first business day of each month, the funds pay a management fee to
the advisor for the previous month at the specified rate. The fee for the
previous month is calculated by multiplying the applicable fee


Statement of Additional Information                                           23

for the fund by the aggregate average daily closing value of a fund's net assets
during the previous month, by a fraction, the numerator of which is the number
of days in the previous month and the denominator of which is 365 (366 in leap
years).

    The management agreement shall continue in effect until the earlier of the
expiration of two years from the date of its execution or until the first
meeting of shareholders following such execution and for as long thereafter as
its continuance is specifically approved at least annually by (1) the funds'
Board of Directors, or by the vote of a majority of outstanding votes (as
defined in the Investment Company Act) and (2) the vote of a majority of the
directors of the funds who are not parties to the agreement or interested
persons of the advisor, cast in person at a meeting called for the purpose of
voting on such approval.

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

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

    The management agreement also provides that the advisor and its officers,
directors and employees may engage in other business, devote time and attention
to any other business whether of a similar or dissimilar nature, and render
services to others.

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

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

    Unified management fees incurred by each fund by class for the fiscal
periods ended November 30, 1998, 1997 and 1996, are indicated in the following
table.

responsible for (i) providing certain officers of the funds and (ii) reviewing
and filing marketing and sales literature on behalf of the funds. The fees and
expenses of FDI are paid by the advisor out of its unified fee.
    

DISTRIBUTOR

   
    The funds' shares are distributed by FDI, a registered broker-dealer. The
distributor is a wholly owned indirect subsidiary of Boston Institutional Group,
Inc. The distributor's principal business address is 60 State Street, Suite

BROKERAGE ALLOCATION

THE EQUITY PORTION OF THE FUNDS

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

    The advisor receives statistical and other information and services,
including research, without cost from brokers and dealers. The advisor evaluates
such information and services, together with all other information that it may
have, in supervising and managing the investments of the funds. Because such


STATEMENT OF ADDITIONAL INFORMATION                                           25


information and services may vary in amount, quality and reliability, their
influence in selecting brokers varies from none to very substantial. The
advisor proposes to continue to place some of the funds' brokerage business
with one or more brokers who provide information and services. Such information
and services will be in addition to and not in lieu of services required to be
performed by the advisor. The advisor does not utilize brokers that provide
such information and services for the purpose of reducing the expense of
providing required services to the funds.

    In the years ended November 30, 1998, 1997 and 1996, the brokerage
commissions of each fund were as follows:

   
FUND                      1998       1997       1996
- -------------------------------------------------------
Strategic Allocation:   $198,409   $127,134   $22,060
Conservative
- -------------------------------------------------------
Strategic Allocation:   521,010     337,258    81,203
Moderate
- -------------------------------------------------------
Strategic Allocation:   359,809     254,195    74,216
Aggressive
- -------------------------------------------------------
    

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

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

THE FIXED-INCOME PORTION OF THE FUNDS

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

   
INFORMATION ABOUT FUND SHARES

    Each of the three funds named on the front of this Statement of Additional
Information is a series of shares issued by American Century Strategic Asset
Allocations, Inc. In addition, each series (or fund) may be divided into
separate classes. See "Multiple Class Structure" that follows. Additional funds
and classes may be added without a shareholder vote.

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


26                                                 American Century Investments


    The assets belonging to each series or class of shares are held separately
by the custodian and the shares of each series or class represent a beneficial
interest in the principal, earnings and profit (or losses) of investment and
other assets held for each series or class. Your rights as a shareholder are the
same for all series or class of securities unless otherwise stated. Within their
respective series or class, all shares have equal redemption rights. Each share,
when issued, is fully paid and non-assessable.

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

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

MULTIPLE CLASS STRUCTURE

   
    The funds' Board of Directors has adopted a multiple class plan (the
Multiclass Plan) pursuant to Rule  18f-3 adopted by the SEC. Pursuant to such
plan, the funds may issue up to four classes of shares: an Investor Class, an
Institutional Class, a Service Class and an Advisor Class. Not all funds offer
all four classes.

    The Investor Class is made available to investors directly without any load
or commission, for a single unified management fee. The Institutional, Service
and Advisor Classes are made available to institutional shareholders or through
financial intermediaries that do not require the same level of shareholder and
administrative services from the advisor as Investor Class shareholders. As a
result, the advisor is able to charge these classes a lower management fee. In
addition to the management fee, however, the Advisor Class shares are subject to
a Master Distribution and Shareholder Services Plan (described on this page).
The plan has been adopted by the funds' Board of Directors and initial
shareholder in accordance with Rule 12b-1 adopted by the SEC under the
Investment Company Act.

RULE 12B-1

    Rule 12b-1 permits an investment company to pay expenses associated with the
distribution of its shares in accordance with a plan adopted by the investment
company's Board of Directors and approved by its shareholders. Pursuant to such
rule, the Board of Directors and initial shareholder of the funds' Advisor Class
have approved and entered into a Master Distribution and Shareholder Services
Plan. The Plan is described below.

    In adopting the Plan, the Board of Directors (including a majority of
directors who are not "interested persons" of the funds [as defined in the
Investment Company Act], hereafter referred to as the independent directors)
determined that there was a reasonable likelihood that the Plan would benefit
the funds and the shareholders of the affected class. Pursuant to Rule 12b-1,
information with respect to revenues and expenses under the Plan is presented to
the Board of Directors quarterly for its consideration in connection with its
deliberations as to the continuance of the Plan. Continuance of the Plan must be
approved by the Board of Directors (including a majority of the independent
directors) annually. The Plan may be amended by a vote of the Board of Directors
(including a majority of the independent directors), except that the Plan may
not be amended to materially increase the amount to be spent for distribution
without majority approval of the shareholders of the affected class. The Plan
terminates automatically in the event of an assignment and may be terminated
upon a vote of a majority of the independent directors or by vote of a majority
of the outstanding voting securities of the affected class.
    

    All fees paid under the Plan will be made in accordance with Section 26 of
the Rules of Fair Practice of the National Association of Securities Dealers.

   
MASTER DISTRIBUTION AND SHAREHOLDER SERVICES PLAN

    As described in the Prospectus, the funds' Advisor Class of shares are also
made available to participants in employer-sponsored retirement or savings plans
and to persons purchasing through financial intermediaries such as banks,
broker-dealers and insurance companies. The funds' distributor enters into
con-
    


Statement of Additional Information                                           27


tracts with various banks, broker-dealers, insurance companies and other
financial intermediaries, with respect to the sale of the funds' shares and/or
the use of the funds' shares in various investment products or in connection
with various financial services.

    Certain recordkeeping and administrative services that are provided by the
funds' transfer agent for the Investor Class shareholders may be performed by
a plan sponsor (or its agents) or by a financial  intermediary for shareholders
in the Advisor Class. In addition to such services, the financial
intermediaries provide various distribution services.

   
    To enable the funds' shares to be made available through such plans and
financial intermediaries, and to compensate them for such services, the funds'
advisor has reduced its management fee by 0.25% per annum with respect to the
Advisor Class shares and the funds' Board of Directors has adopted a Master
Distribution and Shareholder Services Plan (the Distribution Plan). Pursuant to
such Plan, the Advisor Class shares pay a fee of 0.50% annually of the
aggregate average daily assets of the funds' Advisor Class shares, 0.25% of
which is paid for Shareholder Services (as described below) and 0.25% of which
is paid for distribution services.

    Payments may be made for a variety of shareholder services, including, but
are not limited to, (a) receiving, aggregating and processing purchase, exchange
and redemption requests from beneficial owners (including contract owners of
insurance products that utilize the funds as underlying investment media) of
shares and placing purchase, exchange and redemption orders with the funds'
distributor; (b) providing shareholders with a service that invests the assets
of their accounts in shares pursuant to specific or pre-authorized instructions;
(c) processing dividend payments from a fund on behalf of shareholders and
assisting shareholders in changing dividend options, account designations and
addresses; (d) providing and maintaining elective services such as check writing
and wire transfer services; (e) acting as shareholder of record and nominee for
beneficial owners; (f) maintaining account records for shareholders and/or other
beneficial owners; (g) issuing confirmations of transactions; (h) providing
subaccounting with respect to shares beneficially owned by customers of third
parties or providing the information to a fund as necessary for such
subaccounting; (i) preparing and forwarding shareholder communications from the
funds (such as proxies, shareholder reports, annual and semi-annual financial
statements and dividend, distribution and tax notices) to shareholders and/or
other beneficial owners; and (j)  providing other similar administrative and
sub-transfer agency services. Shareholder services do not include those
activities and expenses that are primarily intended to result in the sale of
additional shares of the funds.

    Distribution services include any activity undertaken or expense incurred
that is primarily intended to result in the sale of Advisor Class shares, which
services may include but are not limited to, (a) the payment of sales
commissions, on-going commissions and other payments to brokers, dealers,
financial institutions or others who sell Advisor Class shares pursuant to
Selling Agreements; (b) compensation to registered representatives or other
employees of  distributor who engage in or support distribution of the funds'
Advisor Class shares; (c) compensation to, and expenses (including overhead and
telephone expenses) of, distributor; (d) the printing of prospectuses,
statements of additional information and reports for other than existing
shareholders; (e) the preparation, printing and distribution of sales literature
and advertising materials provided to the funds' shareholders and prospective
shareholders; (f) receiving and answering correspondence from prospective
shareholders, including distributing prospectuses, statements of additional
information, and shareholder reports; (g) the providing of facilities to answer
questions from prospective investors about fund shares; (h) complying with
federal and state securities laws pertaining to the sale of fund shares; (i)
assisting investors in completing application forms and selecting dividend and
other account options; (j) the providing of other reasonable assistance in
connection with the distribution of fund shares; (k) the organizing and
conducting of sales seminars and payments in the form of transactional and
compensation or promotional incentives; (l) profit on the foregoing; (m) the
payment of "service fees" for the provision of personal, continuing services to
investors, as contemplated by the Rules of Fair

Practice of the NASD and (n) such other distribution and services activities as
the advisor determines may be paid for by the funds pursuant to the terms of
this Agreement and in accordance with Rule 12b-1 of the Investment Company Act.

BUYING AND SELLING FUND SHARES

    Information about buying, selling and exchanging fund shares is contained in
the American Century Investor Services Guide. The guide is available to
investors without charge and may be obtained by  calling us.

VALUATION OF THE FUNDS' SECURITIES

   
    Each fund's net asset value per share (NAV), is  calculated as of the close
of business of the New York Stock Exchange (the Exchange), usually at 4 p.m.
Eastern time each day the Exchange is open for  business. The Exchange has
designated the following holiday closings for 1999: New Year's Day, Martin
Luther King Jr. Day, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day. Although the funds expect
the same holiday schedule to be observed in the future, the Exchange may modify
its holiday schedule at any time.
    

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

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

    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 Directors.

   
    The value of an exchange-traded foreign security is determined in its
national currency as of the close of trading on the foreign exchange on which it
is traded or as of the close of business on the New York Stock Exchange, if that
is earlier. That value is then translated to dollars at the prevailing foreign
exchange rate.
    

    Trading in securities on European and Far Eastern securities exchanges and
over-the-counter markets is normally completed at various times before the close
of business on each day that the New York Stock Exchange is open. If an event
were to occur after the value of a security was established but before the net
asset value per share was determined that was likely to materially change the
net asset value, then that security would be valued at fair value as determined
in accordance with procedures adopted by the Board of Directors.

   
    Trading of these securities in foreign markets may not take place on every
New York Stock Exchange business day. In addition, trading may take place in
various foreign markets on Saturdays or on other days when the New York Stock
Exchange is not open and on which the fund's net asset value is not calculated.
Therefore, such calculation does not take place contemporaneously with the
determination of the prices of many of the portfolio securities used in such
calculation and the value of the fund's portfolio may be affected on days when
shares of the fund may not be purchased or redeemed.
    

TAXES

FEDERAL INCOME TAXES

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


Statement of Additional Information                                           29


butions to shareholders and eliminating shareholders' ability to treat
distributions of the funds in the manner they were realized by the funds.

    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. The dividends from net income may qualify for the 70% dividends
received deduction for corporations to the extent that the fund held shares
receiving the dividend for more than 45 days.

   
    Distributions from gains on assets held greater than 12 months are taxable
as long-term gains regardless of the length of time you have held the shares.
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 distributions of long-term capital gain to you with respect
to such shares.

    Dividends and interest received by a fund on foreign securities may give
rise to withholding and other taxes imposed by foreign countries. Tax
conventions between certain countries and the United States may reduce or
eliminate such taxes. Foreign countries generally do not impose taxes on capital
gains in respect to investments by non-resident investors. The foreign taxes
paid by a fund will reduce its dividends.

    If more than 50% of the value of a fund's total assets at the end of each
quarter of its fiscal year consists of securities of foreign corporations, the
fund may qualify for and make an election with the Internal Revenue Service with
respect to such fiscal year so that fund shareholders may be able to claim a
foreign tax credit in lieu of a deduction for foreign income taxes paid by the
fund. If such an election is made, the foreign taxes paid by the fund will be
treated as income received by you. In order for the shareholder to utilize the
foreign tax credit, the mutual fund shares must have been held for 16 days or
more during the 30-day period, beginning 15 days prior to the ex-dividend date
for the mutual fund shares. The mutual fund must meet a similar holding period
requirement with respect to foreign securities to which a dividend is
attributable. Any portion of the foreign tax credit that is ineligible as a
result of the fund not meeting the holding period requirement will be separately
disclosed and may be eligible as an itemized deduction.

    If a fund purchases the securities of certain foreign investment funds or
trusts called passive foreign investment companies (PFIC), capital gains on the
sale of such holdings will be deemed to be ordinary income regardless of how
long the fund holds its investment. The fund also may be subject to corporate
income tax and an interest charge on certain dividends and capital gains earned
from these investments, regardless of whether such income and gains are
distributed to shareholders. In the alternative, the fund may elect to recognize
cumulative gains on such investments as of the last day of its fiscal year and
distribute it to shareholders. Any distribution attributable to a PFIC is
characterized as ordinary income.

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

    Redemption of shares of a fund (including redemption made in an exchange
transaction) will be a taxable transaction for federal income tax purposes and
shareholders will generally recognize gain or loss in an amount equal to the
difference between the basis of the shares and the amount received.  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 Code, resulting in a postponement of the recognition of
such loss for federal income tax purposes.
    

STATE AND LOCAL TAXES

   
    Distributions also may be subject to state and local taxes, even if all or a
substantial part of such distributions are derived from interest on U.S.
government
    


30                                                  American Century Investments


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 advisor about the tax status of such
distributions in your own state.

HOW FUND PERFORMANCE INFORMATION IS CALCULATED

    The funds may quote performance in various ways. Fund performance may be
shown by presenting one or more performance measurements, including cumulative
total return, average annual total return or yield.

    All performance information advertised by the funds 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.

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

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

    The following tables set forth the average annual total return for the
various classes of the funds for the one-year period and the period since
inception ended November 30, 1998, the last day of the funds' fiscal year.

    In addition to average annual total returns, each fund may quote unaveraged
or cumulative total returns reflecting the simple change in value of an
investment over a stated period, including periods other than one, five and 10
years. Average annual and cumulative total returns may be quoted as percentages
or as dollar amounts and may be calculated for a single investment, a series of
investments, or a series of redemptions over any time period. Total returns may
be broken down into their components of income and capital (including capital
gains and changes in share price) to illustrate the relationship of these
factors and their contributions to total return.

PERMISSIBLE ADVERTISING INFORMATION

   
    From time to time, the funds may, in addition to any other permissible
information, include the  following types of information in advertisements,
supplemental sales literature and reports to  shareholders: (1) discussions of
general economic  or financial principles (such as the effects of  compounding
and the benefits of dollar-cost  averaging); (2) discussions of general economic
trends; (3) presentations of statistical data to  supplement such discussions;
(4) descriptions of past or anticipated portfolio holdings for one or more of
the funds; (5) descriptions of investment strategies  for one or more of the
funds; (6) descriptions or  comparisons of various savings and investment
products (including, but not limited to, qualified retirement plans and
individual stocks and bonds), which may or may not include the funds; (7)
comparisons of investment products (including the funds) with relevant market or
industry indices or other appropriate benchmarks; (8) discussions of fund

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

MULTIPLE CLASS PERFORMANCE ADVERTISING

    Pursuant to the Multiple Class Plan, the funds may issue additional classes
of existing funds or introduce new funds with multiple classes available for
purchase. To the extent a new class is added to an existing fund, the advisor
may, in compliance with SEC and NASD rules, regulations and guidelines, market
the new class of shares using the historical performance information of the
original class of shares. When quoting performance information for the new class
of shares for periods prior to the first full quarter after inception, the
original class' performance will be restated to reflect the expenses of the new
class and for periods after the first full quarter after inception, actual
performance of the new class will be used.

EXPLANATION OF FIXED INCOME SECURITIES RATINGS

   
    As described in the Prospectus, the funds may invest in fixed income
securities. Those investments, however, are subject to certain credit quality
restrictions, as noted in the Prospectus. The following is a summary of the
rating categories referenced in the Prospectus disclosure.
    

<TABLE>
BOND RATINGS

S&P   Moody's   Description
- -------------------------------------------------------------------------------------------
<S>  <C>       <C>
AAA   Aaa       These are the highest ratings assigned by S&P and Moody's to a debt
                obligation and indicates an extremely strong capacity to pay interest and repay
                principal.
- -------------------------------------------------------------------------------------------
AA    Aa        Debt rated in this category is considered to have a very strong
                capacity to pay interest and repay principal and
                differs from AAA/Aaa issues only in a small degree.
- -------------------------------------------------------------------------------------------
A     A         Debt rated A has a strong capacity to pay interest and repay
                principal although it is somewhat more susceptible to the adverse effects of
                changes in circumstances and economic conditions than debt in higher-rated
                categories.
- -------------------------------------------------------------------------------------------
BBB   Baa       Debt rated BBB/Baa is regarded as having an adequate capacity to pay
                interest and repay principal. Whereas it normally exhibits adequate protection
                parameters, adverse economic conditions or changing circumstances are more
                likely to lead to a weakened capacity to pay interest and repay principal for
                debt in this category than in higher-rated categories.
- -------------------------------------------------------------------------------------------
BB    Ba        Debt rated BB/Ba has less near-term vulnerability to default than
                other speculative issues. However, it faces major ongoing uncertainties or
                exposure to adverse business, financial or economic conditions that could lead
                to inadequate capacity to meet timely interest and principal payments. The BB
                rating category also is used for debt subordinated to senior debt that is
                assigned an actual or implied BBB- rating.
- -------------------------------------------------------------------------------------------
B     B         Debt rated B has a greater vulnerability to default but currently
                has the capacity to meet interest payments and principal repayments. Adverse
                business, financial or economic conditions will likely impair capacity or
                willingness to pay interest and repay principal. The B rating category is also
                used for debt subordinated to senior debt that is assigned an actual or implied
                BB/Ba or BB-/Ba3 rating.
- -------------------------------------------------------------------------------------------
CCC   Caa       Debt rated CCC/Caa has a currently identifiable vulnerability to
                default and is dependent upon favorable business, financial and economic
                conditions to meet timely payment of interest and repayment of principal. In the
                event of adverse business, financial or economic conditions, it is not likely to
                have the capacity to pay interest and repay principal. The CCC/Caa rating
                category is also used for debt subordinated to senior debt that is assigned an
                actual or implied B or B-/B3 rating.
- -------------------------------------------------------------------------------------------
CC    Ca        The rating CC/Ca typically is applied to debt subordinated to senior
                debt that is assigned an actual or implied CCC/Caa rating.

BOND RATINGS

S&P   Moody's   Description
- -------------------------------------------------------------------------------------------
C     C         The rating C typically is applied to debt subordinated to senior
               debt, which is assigned an actual or implied
               CCC/Caa3 debt rating. The C rating may be used to cover a situation where a
               bankruptcy petition has been filed, but debt service payments are continued.
- -------------------------------------------------------------------------------------------
CI    -        The rating CI is reserved for income bonds on which no interest is
               being paid.
- -------------------------------------------------------------------------------------------
D     D        Debt rated D is in payment default. The D rating category is used
               when interest payments or principal payments are not made on the date due even
               if the applicable grace period has not expired, unless S&P believes that such
               payments will be made during such grace period. The D rating also will be used
               upon the filing of a bankruptcy petition if debt service payments are
               jeopardized.

  To provide more detailed indications of credit quality, the Standard & Poor's
ratings from AA to CCC may be modified by the addition of a plus or minus sign
to show relative standing within these major rating categories. Similarly,
Moody's adds numerical modifiers (1,2,3) to designate relative standing within
its major bond rating categories. Fitch Investors Service, Inc. also rates bonds
and uses a ratings system that is substantially similar to that used by Standard
& Poor's.
    

COMMERCIAL PAPER RATINGS

   
S&P             Moody's         Description
- --------------------------------------------------------------------------------
A-1             Prime-1         This indicates that the degree of safety
                                regarding timely payment is strong.
                (P-1)           Standard & Poor's rates those issues determined
                                to possess extremely strong safety characteristics
                                as A-1+.
- --------------------------------------------------------------------------------
A-2             Prime-2         Capacity for timely payment on commercial paper
                                is satisfactory, but the relative
                (P-2)           degree of safety is not as high as for issues
                                designated A-1. Earnings trends and coverage ratios,
                                while sound, will be more subject to variation.
                                Capitalization characteristics, while still
                                appropriated, may be more affected by external
                                conditions. Ample alternate liquidity is maintained.
- --------------------------------------------------------------------------------
A-3             Prime-3         Satisfactory capacity for timely repayment.
                                Issues that carry this rating
                (P-3)           are somewhat more vulnerable to the adverse
                                changes in circumstances
                                than obligations carrying the higher designations.

NOTE RATINGS

S&P             Moody's         Description
- --------------------------------------------------------------------------------
SP-1            MIG-1; VMIG-1   Notes are of the highest quality enjoying strong
                                protection from established cash flows of funds
                                for their servicing or from established and
                                broad-based access to the market for refinancing,
                                or both.
- --------------------------------------------------------------------------------
SP-2            MIG-2; VMIG-2   Notes are of high quality, with margins of
                                protection ample, although not so large as in
                                the preceding group.
- --------------------------------------------------------------------------------
SP-3            MIG-3; VMIG-3   Notes are of favorable quality, with all
                                security elements accounted for, but lacking the
                                undeniable strength of the preceding grades.
                                Market access for refinancing, in particular,
                                is likely to be less well
established.
- --------------------------------------------------------------------------------
SP-4            MIG-4; VMIG-4   Notes are of adequate quality, carrying specific
                                risk but having protection and not distinctly
                                or predominantly speculative.

Investment Management, Inc., the investment advisor of the Corporation.

     I hereby consent to the use of this opinion as an exhibit to Post-Effective
Amendment No. 6, referenced above.

                                 Very truly yours,
