                     SUPPLEMENT TO EQUITY FUNDS PROSPECTUS

                        Supplement dated January 2, 1996

                         Prospectus dated March 1, 1995

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

     The disclosure  set forth below  replaces the first  paragraph on page 2 of
the Equity Funds Prospectus:
     SELECT  INVESTORS AND HERITAGE  INVESTORS  seek capital  growth.  The funds
intend to pursue their  investment  objectives by investing  primarily in common
stocks   of   companies    that   are   considered   by   management   to   have
better-than-average  prospects  for  appreciation.  As a matter  of  fundamental
policy,  80% of the assets of Select Investors and of Heritage Investors must be
invested in  securities of companies  that have a record of paying  dividends or
have  committed  themselves  to the payment of regular  dividends,  or otherwise
produce income.

     The  following  paragraph  replaces the first  paragraph  under the heading
"Select Investors, Heritage Investors" on page 8 of the Equity Funds Prospectus:
     Securities of companies chosen for Select Investors and Heritage  Investors
are chosen primarily for their growth  potential.  Additionally,  as a matter of
fundamental  policy,  80% of the  assets of  Select  Investors  and of  Heritage
Investors  must be invested in  securities  of  companies  that have a record of
paying  dividends  or  have  committed  themselves  to the  payment  of  regular
dividends or otherwise  produce income.  The remaining 20% of fund assets may be
invested in any otherwise permissible  securities that the manager believes will
contribute to the funds' stated  investment  objectives.  The income payments of
equity  securities  chosen are only a secondary  consideration;  therefore,  the
income  return  that  Select  and  Heritage  provide  may  not  be  significant.
Otherwise,  Select and Heritage follow the same investment  techniques described
below for Growth, Ultra and Vista.

     The  following  paragraph  replaces the third  paragraph  under the heading
"Select Investors, Heritage Investors" on page 8 of the Equity Funds Prospectus:
     Because of its size,  and because it invests  primarily in securities  that
pay  dividends  or are  committed  to the  payment of  dividends,  Select may be
expected to be the least  volatile of the common  stock funds  described in this
prospectus.

     The following  paragraph  replaces the second  paragraph  under the heading
"Giftrust Investors" on page 9 of the Equity Funds Prospectus:
     A Giftrust is a unique way to give a gift to a child or any individual. You
cannot  establish or make investments in a Giftrust for yourself or your spouse,
nor  can a  Giftrust  be  established  that  designates  anyone  other  than  an
individual  (such as a  corporation,  partnership  or other  profit or nonprofit
organization) as a beneficiary.  To open a Giftrust account, call or write for a
Giftrust information kit. The minimum initial investment in Giftrust is $500.

     The following  paragraph is added  immediately  after the fourth  paragraph
under the heading "Giftrust Investors" on page 9 of the Equity Funds Prospectus:
     A $10 fee will be charged  against  each  Giftrust  account for which a tax
return is filed.  (See "A Tax Note About  Giftrust," page 28.)  Additionally,  a
$100  administrative  fee will be charged against each maturing Giftrust account
to help cover the costs incurred as a result of the Giftrust reaching maturity.

     The  following  paragraph is added  immediately  after the first  paragraph
under the heading  "Twentieth  Century Family of Funds" on page 15 of the Equity
Funds Prospectus:
     The Twentieth Century family of mutual funds now also includes the 35 funds
offered by The Benham Group as a result of the acquisition of Benham  Management
Corporation  ("BMC"),  investment  manager of The  Benham  Group,  by  Twentieth
Century  Companies,  Inc. The Benham Group offers several funds with  investment
objectives  similar to the  Twentieth  Century  funds,  but with  different  fee
structures. You may also wish to consider the funds of The Benham Group for your
investment  needs.  For a  prospectus  and more  information  about those funds,
please call 1-800-331-8331.

     The disclosure set forth below replaces the first two paragraphs  under the
heading  "Reports  to  Shareholders"  found  on  page  24 of  the  Equity  Funds
Prospectus:
     At the end of each quarter,  Twentieth Century will send you a consolidated
statement that summarizes all of your Twentieth  Century  holdings.  At the same
time, you will also receive an individual  statement for each Twentieth  Century
fund you own with complete year-to-date information on activity in your account.
You may at any time also request a statement of your account activity be sent to
you.
     With the exception of the automatic transactions noted below, each time you
invest,  redeem,  transfer or convert shares,  Twentieth Century will send you a
confirmation of the transaction.  Effective  October 1, 1995,  automatic monthly
investment purchases and 403(b) purchases (other than transfers),  and effective
November 1, 1995, conversions made in a Convert-A-Month program,  purchases made
by direct  deposit and transfers  made in a  Transfer-A-Month  program,  will no
longer be  confirmed  immediately,  but rather  will be  confirmed  on your next
consolidated  quarterly  statement.  Please  carefully review all information in
your confirmation or consolidated  statement  relating to transactions to ensure
that your  instructions  have been acted on properly.  Please  notify  Twentieth
Century in writing if there is an error. If you fail to provide  notification of
an error within 30 days of non-automatic  transactions (or within 30 days of the
date of your  consolidated  quarterly  statement,  in the case of the  automatic
transactions noted above) you will be deemed to have ratified the transaction.

     The  disclosure  set forth below  replaces the second  paragraph  under the
heading "A Tax Note About Giftrust" on page 28 of the Equity Funds Prospectus:
     The income of a Giftrust is exempt from federal income tax until it exceeds
$100;  the trustee of the Giftrust files federal income tax returns and pays the
income tax out of the assets of the trust.  A $10 fee will be charged  against a
Giftrust  account in each year that the trustee  files a tax return on behalf of
the  Giftrust.  The  distribution  to the  beneficiary  at the  maturity  of the
Giftrust may be subject to the throwback rules under the Internal  Revenue Code.
The throwback rules may create additional tax liability for a beneficiary who is
age 21 or older at the time the  Giftrust  matures.  More than one trust for the
same  beneficiary may be subject to the provisions of the Internal  Revenue Code
with respect to multiple trusts.

     The disclosure set forth below modifies the section "Management"  beginning
on page 28 of the Equity Funds Prospectus.  A new subheading titled  "Investment
Management" is hereby added immediately  below the heading  "Management" on page
28. The following paragraph is added after the first paragraph on page 29:
     In June 1995,  Twentieth Century  Companies,  Inc.  ("TCC"),  the parent of
Investors  Research,  acquired  Benham  Management  International,  Inc.  In the
acquisition,  Benham Management  Corporation  ("BMC"), the investment adviser to
the Benham  Group of Mutual  Funds,  became a wholly  owned  subsidiary  of TCC.
Certain  employees of BMC will be providing  investment  management  services to
Twentieth  Century  funds,  while certain  Twentieth  Century  employees will be
providing investment management services to Benham funds.

The first two paragraphs appearing on page 30 of the Equity Funds Prospectus are
hereby  deleted.  In addition,  the following two  paragraphs  replace the sixth
paragraph appearing on page 30:

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

TRANSFER AND ADMINISTRATIVE SERVICES
     Twentieth Century Services,  Inc., 4500 Main Street,  Kansas City, Missouri
64111, acts as transfer,  administrative  services and dividend-paying agent for
Twentieth Century. It provides facilities,  equipment and personnel to Twentieth
Century,  and  is  paid  for  such  services  by  Investors  Research.   Certain
record-keeping  services that would otherwise be performed by Twentieth  Century
Services,  Inc.,  may be  performed  by an  insurance  company  or other  entity
providing  similar  services  for  various  retirement  plans  using  shares  of
Twentieth Century as a funding medium or by  broker-dealers  for their customers
investing in shares of Twentieth Century.  Investors Research may elect to enter
into a contract to pay them for such services.

                              Revised June 1, 1995

- --------------------------------------------------------------------------------
    Twentieth Century Investors,  Inc., a member of the Twentieth Century family
of funds,  offers 16 no-load  mutual  funds  covering  a variety  of  investment
opportunities.  Seven of the funds invest primarily in equity securities and are
described in this  prospectus.  Their  investment  objectives  are listed on the
inside cover of this  prospectus.  The nine funds that invest primarily in fixed
income or debt securities are described in a separate prospectus.


NO-LOAD MUTUAL FUNDS

     Twentieth Century's funds are "no-load" investments,  which means there are
no sales charges or  commissions.  Twentieth  Century has no 12b-1 plan or other
deferred sales charges.  There is no minimum  investment  requirement for any of
the funds described in this prospectus except Giftrust  Investors.  However,  if
the value of the shares held in any one fund account is less than $2,500 ($1,000
for UGMA/UTMA  accounts),  you must establish a $50 or greater automatic monthly
investment in each such account.  (See "Automatic Monthly  Investments," page 16
and "Automatic Redemption of Shares," page 22.)
     This  prospectus  gives you information  about  Twentieth  Century that you
should know before  investing.  You should read this  prospectus  carefully  and
retain it for  future  reference.  Additional  information  is  included  in the
statement  of  additional  information  dated March 1, 1995,  and filed with the
Securities and Exchange  Commission.  It is  incorporated  in this prospectus by

                         INFORMATION REGARDING THE FUNDS
- --------------------------------------------------------------------------------

   INFORMATION ABOUT INVESTMENT                                                 
   POLICIES OF THE FUNDS                                                        
        Twentieth Century has adopted certain investment restrictions applicable
   to the funds that are set forth in the statement of  additional  information.
   Those  restrictions,  as  well  as the  investment  objectives  of the  funds
   identified on the inside front cover page of this  prospectus,  and any other
   investment  policies designated as "fundamental" in this prospectus or in the
   statement of additional  information,  cannot be changed without  shareholder
   approval.  The funds have  implemented  additional  investment  policies  and
   practices  to guide  their  activities  in the  pursuit  of their  respective
   investment  objectives.  These  policies and  practices,  which are described
   throughout this  prospectus,  are not designated as fundamental  policies and
   may be changed without shareholder approval.                                 
        The  descriptions  that follow are  designed to help you choose the fund
   that best fits your investment  objectives.  You may want to pursue more than
   one objective by investing in more than one of these funds.                  
                                                                                
   EQUITY FUNDS                                                                 
        All of Twentieth  Century's  equity funds and the equity  portion of the
   portfolio  of  Balanced   Investors  seek  capital  growth  by  investing  in
   securities,  primarily  common  stocks,  that meet  certain  fundamental  and
   technical  standards  of  selection  and have,  in the  opinion of  Twentieth
   Century's management, better-than-average potential for appreciation. So long
   as a sufficient  number of such securities are available,  Twentieth  Century
   intends to stay fully invested in these securities regardless of the movement
   of stock prices generally. In most circumstances,  the funds' actual level of
   cash and cash equivalents  will fluctuate  between 0% and 10% of total assets
   with 90% to 100% of its assets  committed  to equity  and  equity  equivalent
   investments.  The funds may purchase securities only of companies that have a
   record of at least three years continuous operation.                         
                                                                                
   SELECT INVESTORS, HERITAGE INVESTORS                                         
        Securities  of companies  chosen for Select and Heritage  Investors  are
   chosen  primarily for their growth  potential.  Additionally,  as a matter of
   fundamental  policy the companies must have a record of paying,  or must have
   committed  themselves  to the  payment of  regular  dividends.  Their  income
   payments are only a secondary  consideration;  therefore,  the income  return
   that Select and Heritage  provide may not be significant.  Otherwise,  Select
   and  Heritage  follow  the same  investment  techniques  described  below for
   Growth, Ultra and Vista.                                                     
        Since  Select is one of the  largest of  Twentieth  Century's  funds and
   Heritage  is  substantially  smaller,  Select will invest in shares of larger
   companies with larger share trading volume,  and Heritage will tend to invest
   in smaller  companies  with smaller share trading  volume.  However,  the two
   funds are not mutually  exclusive,  and a given security may be owned by both
   funds.  For the reasons  stated  below under the caption  "Growth,  Ultra and
   Vista  Investors,"  it should be expected that Heritage will be more volatile
   and subject to greater short-term risk and long-term opportunity than Select.
        Because of its size,  and because it can invest only in securities  that
   pay  dividends or are  committed to the payment of  dividends,  Select may be
   expected to be the least volatile of the common stock funds described in this
   prospectus.                                                                  
                                                                                
   GROWTH INVESTORS, ULTRA INVESTORS,                                           
   VISTA INVESTORS                                                              
        Management  selects,  for the  portfolios  of  Growth,  Ultra and Vista,
   securities of companies  whose earnings and revenue trends meet  management's
   standards of selection.  They then  determine to which of the three funds the
   selected securities would most contribute.                                   
        Large,   established   companies  are  generally  allocated  to  Growth.
   Medium-sized  and smaller  companies are allocated to Ultra and Vista.  As of
   February  1,  1995,  the  size  of  the  companies  (as  reflected  by  their
   capitalizations) held by the funds is as follows:

                                             Median Capitalization
                                               of Companies Held
- --------------------------------------------------------------------------------
   Growth Investors                             $ 7,658,739,000
   Ultra Investors                              $ 1,946,368,000
   Vista Investors                              $   623,861,000
- --------------------------------------------------------------------------------

        The median  capitalization  of the  companies in a given fund may change
   over  time.  In  addition,  the  criteria  outlined  above  are not  mutually
   exclusive, and a given security may be owned by more than one of the funds.
        The size of the fund and of its portfolio  companies  tends to give each
   fund its own  characteristics  of volatility and risk. These differences come
   about because developments such as new or improved products or methods, which
   would be relatively  insignificant to a large portfolio  company,  may have a
   substantial impact on the earnings and revenues of a small company and create
   a greater  demand and a higher value for its shares.  However,  a new product
   failure  which could  readily be absorbed  by a large  portfolio  company can
   cause a rapid decline in the value of the shares of a smaller company. Hence,
   it could be expected that funds investing in smaller  companies would be more
   volatile than funds investing in larger companies.

   GIFTRUST INVESTORS
        Giftrust  Investors is the smallest of the common stock funds  described
   in this  prospectus  and may be considered  the most  volatile.  Selection of
   securities for the portfolio of Giftrust is discussed  under "Equity  Funds,"
   page 8.
        A  Giftrust  investment  is a unique  way to give a gift to a  child,  a
   charity or any  individual  or  organization.  (You may not establish or make
   investments  in a Giftrust for  yourself or your  spouse.) To open a Giftrust
   account,  call or write for a Giftrust  Information  Kit. The minimum initial
   investment in Giftrust is $250.
        The shares in a  Giftrust  are held in trust by an  independent  trustee
   until the maturity date you specify. The duration of the trust may be as long
   as you wish,  but must be at least 10 years  from the time you make the first
   investment  in the  Giftrust  or  until  the  recipient  reaches  the  age of
   majority,  whichever is later.  The recipient will then receive the shares in
   the  account.  The  Giftrust is  irrevocable.  Before the  maturity  date you
   specify,  neither you nor the beneficiary may amend the terms of the trust in
   any way. Additional  investments may be made in amounts of $50 or more at any
   time without affecting the maturity date.
        At the maturity of the Giftrust, the beneficiary may continue to own the
   Giftrust shares but, except for reinvestment of  distributions,  may not make
   additional Giftrust investments.
        The tax laws  applicable  to trusts in general  are quite  complex.  You
   should  consider  consulting  your tax  adviser  before  opening  a  Giftrust
   account.  (For  information  on  Giftrusts  and taxes,  see "A Tax Note About
   Giftrust," page 28.)

   BALANCED FUND

   BALANCED INVESTORS
        Balanced Investors seeks capital growth and current income. Selection of
   securities for the equity portion of its portfolio is discussed under "Equity
   Funds," page 8.
        Since a portion of the fund's portfolio will be invested in fixed income
   securities,  the opportunity for capital  appreciation  may be expected to be
   less than the other funds described in this prospectus.
        Management intends to maintain approximately 40% of the fund's assets in
   fixed income  securities with a minimum of 25% of that amount in fixed income
   senior  securities.  The fixed income  securities  in the fund will be chosen
   based on their level of income  production and price stability.  The fund may
   invest in a  diversified  portfolio of debt and other  fixed-rate  securities
   payable in United  States  currency.  These may  include  obligations  of the
   United  States  government,  its  agencies and  instrumentalities;  corporate
   securities (bonds,  notes,  preferreds and convertible issues), and sovereign
   government, municipal, mortgage-backed and other asset-backed securities.
        There are no maturity restrictions on the fixed income securities in 
   which the fund


                                        9

<PAGE>

   invests.  Under normal  market  conditions  the weighted  average  portfolio
   maturity  will be in the three- to 10-year  range.  Management  will actively
   manage the portfolio,  adjusting the weighted average  portfolio  maturity in
   response to  expected  changes in interest  rates.  During  periods of rising
   interest rates, a shorter  weighted  average maturity may be adopted in order
   to reduce the effect of bond price  declines  on the fund's net asset  value.
   When interest  rates are falling and bond prices  rising,  a longer  weighted
   average portfolio maturity may be adopted.
        It is management's  intention to invest the fund's fixed income holdings
   in  high-grade  securities.  At least  80% of  fixed  income  assets  will be
   invested in  securities  which at the time of purchase  are rated  within the
   three  highest  categories  by a  nationally  recognized  statistical  rating
   organization  [at least A by Moody's  Investors  Service,  Inc.  (Moody's) or
   Standard & Poor's Corp. (S&P)].
        The  remaining  portion of the fixed  income  assets may be  invested in
   issues in the fourth highest  category (Baa by Moody's or BBB by S&P), or, if
   not  rated,  are  of  equivalent  investment  quality  as  determined  by the
   management  and  which,   in  the  opinion  of  management,   can  contribute
   meaningfully to the fund's results without compromising its objectives.  Such
   issues  might  include  a  lower-rated  issue  where  research  suggests  the
   likelihood of a rating increase;  or a convertible  issue of a company deemed
   attractive by the equity management team.  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 or changing circumstances.  (See, "An Explanation
   of  Fixed  Income   Securities   Ratings"  in  the  statement  of  additional
   information.)

   OTHER INVESTMENT PRACTICES
        For additional information,  see "Investment  Restrictions Applicable to
   All Series of Shares" in the statement of additional information.

   FOREIGN SECURITIES
        Each of  Twentieth  Century's  funds  described in this  prospectus  may
   invest  an  unlimited  amount  of its  assets in the  securities  of  foreign
   issuers,  primarily from developed  markets,  when these  securities meet its
   standards of selection.  The funds may make such investments  either directly
   in foreign  securities,  or by  purchasing  Depositary  Receipts  ("DRs") for
   foreign  securities.  DRs are securities listed on exchanges or quoted in the
   over-the-counter  market in one country but  represent  the shares of issuers
   domiciled in other  countries.  DRs may be sponsored or  unsponsored.  Direct
   investments in foreign  securities  may be made either on foreign  securities
   exchanges or in the over-the-counter markets.
        Subject to their  individual  investment  objectives  and policies,  the
   funds 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 funds will limit
   their purchase of debt securities to investment grade obligations.
        Investments in foreign  securities may present certain risks,  including
   those  resulting  from  fluctuations  in  currency  exchange  rates,   future
   political  and  economic   developments,   reduced   availability  of  public
   information  concerning  issuers,  and the fact that foreign  issuers are not
   generally  subject to uniform  accounting,  auditing and financial  reporting
   standards or to other  regulatory  practices and  requirements  comparable to
   those applicable to domestic issuers.

   FORWARD CURRENCY
   EXCHANGE CONTRACTS
        Some of the foreign  securities  held by the funds may be denominated in
   foreign currencies. Other securities, such as DRs, may be denominated in U.S.
   dollars,  but have a value that is dependent on the  performance of a foreign
   security, as valued in the currency of its home coun-


                                       10

<PAGE>

   try.  As a result,  the value of the funds'  portfolios  may be  affected by
   changes in the exchange rates between foreign  currencies and the dollar,  as
   well as by changes in the market  values of the  securities  themselves.  The
   performance of foreign  currencies  relative to the dollar may be a factor in
   the overall performance of the funds.
        To  protect  against  adverse   movements  in  ex-change  rates  between
   currencies,  the funds may,  for hedging  purposes  only,  enter into forward
   currency exchange  contracts.  A forward currency exchange contract obligates
   the fund to  purchase  or sell a  specific  currency  at a  future  date at a
   specific price.
        A fund may elect to enter into a forward currency exchange contract with
   respect to a specific purchase or sale of a security,  or with respect to the
   fund's portfolio positions generally.
        By entering into a forward  currency  exchange  contract with respect to
   the  specific  purchase  or  sale  of a  security  denominated  in a  foreign
   currency,  a fund can  "lock  in" an  exchange  rate  between  the  trade and
   settlement  dates for that  purchase  or sale.  This  practice  is  sometimes
   referred to as  "transaction  hedging." Each fund may enter into  transaction
   hedging contracts with respect to all or a substantial portion of its foreign
   securities trades.
        When the manager  believes  that a  particular  currency  may decline in
   value compared to the dollar, a fund may enter into forward currency exchange
   contracts to sell the value of some or all of the fund's portfolio securities
   either  denominated  in,  or  whose  value is tied to,  that  currency.  This
   practice  is  sometimes  referred to as  "portfolio  hedging." A fund may not
   enter into a portfolio  hedging  transaction  where it would be  obligated to
   deliver an amount of foreign currency in excess of the aggregate value of its
   portfolio  securities or other assets  denominated in, or whose value is tied
   to, that currency.
        Each fund will make use of the  portfolio  hedging to the extent  deemed
   appropriate by the manager. However, it is anticipated that a fund will enter
   into portfolio hedges much less frequently than transaction hedges.
        If a fund enters into a forward contract, the fund, when required,  will
   instruct its custodian bank to segregate cash or liquid high-grade securities
   in a separate  account in an amount  sufficient to cover its obligation under
   the contract.  Those assets will be valued at market daily,  and if the value
   of the segregated securities declines,  additional cash or securities will be
   added so that the value of the  account  is not less  than the  amount of the
   fund's  commitment.  At any given time,  no more than 10% of a fund's  assets
   will be  committed  to a  segregated  account in  connection  with  portfolio
   hedging transactions.
        Predicting the relative  future values of currencies is very  difficult,
   and there is no assurance that any attempt to protect a fund against  adverse
   currency  movements  through the use of forward currency  exchange  contracts
   will be  successful.  In  addition,  the  use of  forward  currency  exchange
   contracts  tends to limit  the  potential  gains  that  might  result  from a
   positive  change in the  relationships  between the foreign  currency and the
   U.S. dollar.

   PORTFOLIO TURNOVER
        The  total  portfolio  turnover  rates  of the  funds  are  shown in the
   Financial Highlights table on pages 5, 6 and 7 of this prospectus.
        Investment  decisions to purchase and sell  securities  are based on the
   anticipated  contribution of the security in question to a fund's objectives.
   The rate of  portfolio  turnover is  irrelevant  when  management  believes a
   change is in order to achieve those  objectives and  accordingly,  the annual
   portfolio turnover rate cannot be anticipated.
        The  portfolio  turnover  of each fund may be higher  than other  mutual
   funds with similar  investment  objectives.  Higher  turnover  would generate
   correspondingly greater brokerage commissions, which is a cost that each fund
   pays  directly.  Portfolio  turnover may also affect the character of capital
   gains, if any,  realized and distributed by a fund since  short-term  capital
   gains are taxable as ordinary income. 

   REPURCHASE AGREEMENTS
        Each fund may invest in  repurchase  agreements  when such  transactions
   present an attractive short-term return on cash that is not



                                       11

<PAGE>

   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  repurchase  it on a
   specified date in the future at an agreed-upon  price.  The repurchase  price
   reflects an  agreed-upon  interest  rate during the time the fund's  money is
   invested in the security.
        Since the security  purchased  constitutes  security for the  repurchase
   obligation, a repurchase agreement can be considered a loan collateralized by
   the security  purchased.  The fund's risk is the ability of the seller to pay
   the  agreed-upon  repurchase  price on the  repurchase  date.  If the  seller
   defaults,  the fund may incur costs in  disposing  of the  collateral,  which
   would reduce the amount  realized  thereon.  If the seller seeks relief under
   the  bankruptcy  laws,  the  disposition  of the collateral may be delayed or
   limited.  To the extent the value of the security  decreases,  the fund could
   experience a loss.
        The funds will limit  repurchase  agreement  transactions  to securities
   issued by the United States 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.
        No fund will invest more than 15% of its assets in repurchase agreements
   maturing in more than seven days.

   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.  Certain derivative  securities are more accurately
   described as "index/structured  securities."  Index/structured securities are
   derivative  securities  whose value or  performance is linked to other equity
   securities  (such as  DRs),  currencies,  interest  rates,  indexes  or other
   financial  indicators  ("reference  indexes").  No  fund  may  invest  in  an
   index/structured  security  unless the reference  index or the  instrument to
   which it relates is an eligible  investment for the fund. For example, a bond
   whose interest rate was indexed to the return on two-year treasury securities
   would be a permissible investment for Balanced Investors (assuming it met the
   other  requirements  for the fund),  while a bond whose return was indexed to
   the price of oil would not be a permissible investment.
        The return,  interest rate or, unlike most fixed income securities,  the
   principal amount payable at maturity of an  index/structured  security may be
   increased  or  decreased,  depending  upon  changes in the  reference  index.
   Index/structured  securities  may be positively or negatively  indexed.  That
   means that an  increase  in the  reference  index may  produce an increase or
   decrease in the return, interest rate or value at maturity of the security.
        No  purchases  will  be  made  of  index/structured   securities  having
   "leverage"  characteristics.  This means that no investments  will be made in
   securities  whose change in return,  interest  rate or value at maturity is a
   multiple  of the  change in the  reference  index.  With  regard to  Balanced
   Investors, in no event will an index/structured  security be purchased if its
   addition  to  Balanced  Investors'  fixed  income  portfolio  would cause the
   expected interest rate  characteristics of its fixed income portfolio to fall
   outside the expected interest rate  characteristics of a fund having the same
   permissible weighted average portfolio maturity range that does not invest in
   index/structured securities.
        Because their performance is tied to a reference index, a fund investing
   in  index/structured  securities,  in addition to being exposed to the credit
   risk of the issuer of the security, will also bear the market risk of changes
   in the reference index.
        The  board of  directors  has  approved  management's  policy  regarding
   investments in derivative securities. That policy specifies factors that must
   be  considered in connection  with a purchase of derivative  securities.  The
   policy  also  establishes  a  committee  that must  review  certain  proposed
   purchases before the purchases


                                       12

<PAGE>
   can be made. Management will report on fund activity in derivative securities
   to the board of directors as  necessary.  In addition,  the board will review
   management's policy for investments in derivative securities annually.

   PORTFOLIO LENDING
        In order to realize additional income,  each fund may lend its portfolio
   securities  to  persons  not  affiliated  with it and who  are  deemed  to be
   creditworthy.  Such  loans must be secured  continuously  by cash  collateral
   maintained on a current basis in an amount at least equal to the market value
   of the securities  loaned,  or by irrevocable  letters of credit.  During the
   existence of the loan,  the fund must  continue to receive the  equivalent of
   the interest and dividends  paid by the issuer on the  securities  loaned and
   interest on the investment of the collateral. The fund must have the right to
   call the loan and  obtain  the  securities  loaned at any time on five  days'
   notice,  including  the right to call the loan to enable the fund to vote the
   securities.  Such  loans may not  exceed  one-third  of the fund's net assets
   taken at  market.  Interest  on loaned  securities  may not exceed 10% of the
   annual gross income of the fund (without offset for realized  capital gains).
   The portfolio  lending  policy  described in this  paragraph is a fundamental
   policy  that  may be  changed  only  by a vote  of a  majority  of  Twentieth
   Century's shareholders.
        Twentieth  Century is  indemnified  against  loss on the loans by United
   States Trust Company of New York.

   WHEN-ISSUED SECURITIES
        Each of the funds may  sometimes  purchase new issues of securities on a
   when-issued  basis without  limit when,  in the opinion of the manager,  such
   purchases  will further the  investment  objectives of the fund. The price of
   when-issued  securities is established at the time  commitment to purchase is
   made.  Delivery of and payment for these securities  typically occur 15 to 45
   days after the  commitment  to  purchase.  Market  rates of  interest on debt
   securities  at the  time of  delivery  may be  higher  or  lower  than  those
   contracted for on the when-issued  security.  Accordingly,  the value of such
   security may decline  prior to delivery,  which could result in a loss to the
   fund. A separate  account for each fund  consisting  of cash or  high-quality
   liquid  debt  securities  in an  amount  at least  equal  to the  when-issued
   commitments will be established and maintained with the custodian.  No income
   will accrue to the fund prior to delivery. RULE 144A SECURITIES

   RULE 144A SECURITIES
        Each  fund will not  invest  more  than 15% of its  assets  in  illiquid
   securities   (securities   that  may  not  be  sold  within   seven  days  at
   approximately  the price  used in  determining  the net  asset  value of fund
   shares),  including restricted  securities.  Although securities which may be
   resold  only  to  qualified  institutional  buyers  in  accordance  with  the
   provisions  of Rule 144A  under  the  Securities  Act of 1933 are  considered
   "restricted  securities," each fund may purchase Rule 144A securities without
   regard to the 15% limitation described above when those securities present an
   attractive  investment  opportunity  and otherwise meet  Twentieth  Century's
   criteria of selection.
        With respect to  securities  eligible  for resale  under Rule 144A,  the
   staff of the Securities  and Exchange  Commission 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
   Twentieth  Century has delegated the day-to-day  function of determining  the
   liquidity  of Rule 144A  securities  to the  manager.  The board  retains the
   responsibility to monitor the implementation of the guidelines and procedures
   it has adopted.
        Since the secondary market for such securi-


                                       13
<PAGE>

   ties is limited to certain  institutional  investors,  the liquidity of such
   securities may be limited accordingly and a fund may from time to time hold a
   Rule 144A security that is illiquid. In such an event, Twentieth Century will
   consider appropriate remedies to minimize the effect on the fund's liquidity.

   SHORT SALES
        Twentieth  Century's  funds  described in this  prospectus may engage in
   short sales if, at the time of the short sale, the fund owns or has the right
   to acquire an equal amount of the security  being sold short at no additional
   cost. These  transactions allow a fund to hedge against price fluctuations by
   locking in a sale price for securities it does not wish to sell immediately.
        A fund may make a short sale 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  and for  purposes  of  satisfying
   certain tests applicable to regulated investment companies under the Internal
   Revenue Code.

   PERFORMANCE ADVERTISING
        From time to time,  Twentieth  Century may advertise  performance  data.
   Fund  performance  may  be  shown  by  presenting  one  or  more  performance
   measurements,  including  cumulative  total  return or average  annual  total
   return and, with respect to the balanced fund, yield.
        Cumulative  total return data is computed by considering all elements of
   return,  including reinvestment of dividends and capital gains distributions,
   over a stated  period of time.  Average  annual total return is determined by
   computing the annual  compound return over a stated period of time that would
   have  produced a fund's  cumulative  total return over the same period if the
   fund's performance had remained constant throughout.
        A  quotation  of yield  reflects a fund's  income  over a stated  period
   expressed as a percentage of the fund's share price.
        With respect to Balanced Investors, yield is calculated by adding over a
   30-day (or  one-month)  period all interest and dividend  income (net of fund
   expenses)  calculated on each day's market  values,  dividing this sum by the
   average number of fund shares  outstanding  during the period, and expressing
   the result as a  percentage  of the fund's share price on the last day of the
   30-day (or  one-month)  period.  The percentage is then  annualized.  Capital
   gains and losses are not included in the calculation.
        Yields  are  calculated   according  to  accounting   methods  that  are
   standardized  in  accordance  with SEC rules  for all  stock and bond  funds.
   Because  yield  accounting  methods  differ from the  methods  used for other
   accounting  purposes,  the fund's yield may not equal the income paid on your
   shares or the income reported in the fund's financial statements.
        The funds may also include in advertisements data comparing  performance
   with the performance of non-related  investment  media,  published  editorial
   comments and performance rankings compiled by independent organizations (such
   as  Lipper   Analytical   Services  or  Donoghue's  Money  Fund  Report)  and
   publications  that  monitor  the  performance  of mutual  funds.  Performance
   information may be quoted  numerically or may be presented in a table,  graph
   or other  illustration.  In  addition,  fund  performance  may be compared to
   well-known  indices of market  performance  including  the  Standard & Poor's
   (S&P) 500 Index and the Dow Jones  Industrial  Average.  Fund performance may
   also be compared to other funds in the Twentieth  Century family. It may also
   be combined or blended with other funds in the Twentieth Century family,  and
   that combined or blended  performance  may be compared to the same indices to
   which individual funds may be compared.
        All  performance  information  advertised  by the 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.

   value of less than $2,500 [$1,000 for Uniform  Gifts/Transfers  to Minors Act
   ("UGMA/UTMA")  accounts],  you must establish an automatic monthly investment
   to purchase  additional  shares in each such fund account in an amount of $50
   or more.**  (See  "Automatic  Monthly  Investments,"  page 16 and  "Automatic

      (1) Instruct your bank to wire funds to the Boatmen's  First National Bank
          of Kansas City, Missouri, ABA routing number 101000035.

      (2) BE SURE TO SPECIFY ON THE WIRE:
          (A) TWENTIETH CENTURY INVESTORS, INC.

          (C) YOUR NAME.
          (D) YOUR CITY AND STATE.
          (E) YOUR TAXPAYER IDENTIFICATION NUMBER.

<PAGE>

        Wired funds are  considered  received on the day they are  deposited  in
   Twentieth  Century's  account  if they  are  deposited  before  the  close of
   business on the New York Stock  Exchange,  usually 3 p.m.  Central time. (See
   "When Share Price Is Determined," page 25.)


   AUTOMATIC MONTHLY INVESTMENTS
        Once your account is open,  you may make  investments  automatically  by
   electing  the  service  authorizing  Twentieth  Century  to draw on your bank
   account.  SUCH INVESTMENTS MUST BE IN AMOUNTS OF NOT LESS THAN $50 IN ANY ONE
   ACCOUNT.   You  should   inquire  at  your  bank  whether  it  will  honor  a
   preauthorized electronic draft. Contact Twentieth Century if your bank cannot
   accept electronic drafts or if it requires additional documentation.
        You may change the date or amount of your monthly  investment anytime by
   letter or telephone  call to Twentieth  Century at least five  business  days
   before the change is to become effective.


   ADDITIONAL INFORMATION
   ABOUT INVESTMENTS
         TWENTIETH CENTURY CANNOT ACCEPT INVESTMENTS SPECIFYING A CERTAIN PRICE,
   DATE OR NUMBER OF SHARES AND WILL RETURN THESE INVESTMENTS.
        Once  you  have  mailed  or  otherwise   trans-mitted   your  investment
   instruction to Twentieth Century, it may not be modified or cancelled.
        Each fund  reserves  the right to suspend  the  offering of shares for a
   period of time,  and each fund  reserves  the  right to reject  any  specific
   purchase order including  purchases by exchange or conversion.  Additionally,
   purchases  may be refused  if, in the opinion of the  manager,  they are of a
   size that would disrupt the management of the funds.
        Twentieth Century intends,  upon 60 days' prior notice, to involuntarily
   redeem  shares  in any  account  that  does  not meet  the  minimum  value or
   automatic  monthly  investment   requirements  applicable  to  such  account.
   Twentieth  Century  reserves the right to change the amount of these minimums
   from time to time or waive  them in whole or in part for  certain  classes of
   investors.  (See "Automatic  Monthly  Investments,"  this page and "Automatic
   Redemption of Shares," page 22.)
        Transactions  in  shares  of the funds may be  executed  by  brokers  or
   investment advisers who charge a fee for their services.  You should be aware
   of the fact that  these  transactions  may be made  directly  with  Twentieth
   Century without incurring such fees.

   TAX IDENTIFICATION NUMBER
         You must furnish Twentieth Century with your tax identification  number
   and  state  whether  or  not  you  are  subject  to  withholding   for  prior
   under-reporting,  certified  under  penalties of perjury as prescribed by the
   Internal  Revenue  Code  and  Regulations.   Unless   previously   furnished,
   investments   received   without  such   certifications   will  be  returned.
   Instructions to convert or transfer shares held in established  accounts will
   be refused unless the  certifications  have been provided,  and redemption of
   such shares will be subject to federal tax withholding at the rate of 31%. In
   addition,  redemption  proceeds will be reduced by $50 to reimburse Twentieth
   Century for the  penalty  that the IRS will impose on the company for failure
   to report your tax identification number on information reports. Please avoid
   these penalties by correctly furnishing your tax identification number.

   CERTIFICATES
        At your written request,  Twentieth  Century will issue negotiable stock
   certificates.   Unless  your  shares  are  purchased   with  wired  funds,  a
   certificate  will not be issued  until 15 days have  elapsed from the time of
   purchase,  or Twentieth Century has satisfactory proof of payment,  such as a
   copy of your cancelled check. Negotiable certificates



                                       16
<PAGE>

   will not be issued for fund  shares  held in  accounts  that do not meet the
   minimum account value requirement for that fund.

   SPECIAL SHAREHOLDER SERVICES
        You may  establish one or more special  services  designed to provide an
   easy way to do business with Twentieth Century. By electing these services on
   your application or by completing the appropriate forms, you may authorize:

    o Investments by phone.
    o Automatic Monthly Investments.
    o Conversions and redemptions by phone.
    o Conversions and redemptions in writing signed by any one registered owner.
    o Redemptions without a signature guarantee.
    o Transmission of redemption proceeds by wire or electronic funds transfer.

        An election to establish  any of the above  services,  except  Automatic
   Monthly  Investments,  will also apply to all existing and future accounts in
   the Twentieth  Century family of funds listed under the same social  security
   number or employer identification number.
        With  regard to the service  which  enables you to convert and redeem by
   phone or in writing signed by only one  registered  owner and with respect to
   redemptions,  without a signature guarantee,  Twentieth Century, its transfer
   agent  and  investment  adviser  will  not be  responsible  for any  loss for
   instructions  that they  reasonably  believe are genuine.  Twentieth  Century
   intends to employ reasonable procedures to confirm that instructions received
   by Twentieth  Century for your account in fact are genuine.  Such  procedures
   will  include  requiring  personal  information  to verify  the  identity  of
   callers,  providing  written  confirmations  of telephone  transactions,  and
   recording  telephone calls. If Twentieth  Century does not employ  reasonable
   procedures to confirm the genuineness of instructions, then Twentieth Century
   may be liable for losses due to unauthorized or fraudulent instructions.

   HOW TO CONVERT YOUR
   INVESTMENT FROM ONE TWENTIETH
   CENTURY FUND TO ANOTHER
        Subject to any applicable minimum initial investment  requirements,  you
   may  exchange  ("convert")  your  shares to shares of any of the other  funds
   (except Giftrust  Investors) in the Twentieth Century family of funds. Please
   call the Investors Line for a prospectus and additional information about the
   other funds in the Twentieth Century family of funds.
        Except as noted below, conversions from any one fund account are limited
   to four  times in any one  calendar  year.  In  addition,  the  shares  being
   converted  and the  shares of each fund  being  acquired  must have a current
   value of at least $500 and otherwise meet the minimum investment requirement,
   if any, of the fund being acquired. If you would like to convert your shares,
   please call the Investors Line for a prospectus  and  additional  information
   about  the  other  funds in the  Twentieth  Century  family  of  funds.  (See
   "Additional Information About Conversions," page 18.)
        Shares of the funds  (except  Giftrust  Investors)  may be  received  in
   exchange  for  shares  of any  series  issued  by the  other  members  of the
   Twentieth Century family of funds.
        THE CONVERSION PRIVILEGE IS NOT DESIGNED TO AFFORD SHAREHOLDERS A WAY TO
   PLAY SHORT-TERM  SWINGS IN THE MARKET.  TWENTIETH CENTURY IS NOT SUITABLE FOR
   THAT PURPOSE.

   BY TELEPHONE
        You may convert  your shares by phone if you have  authorized  Twentieth
   Century to accept telephone  instructions.  (Before calling, read "Additional
   Information About Conversions," page 18.)

   BY MAIL
        You may direct Twentieth Century in writing to convert your shares.



                                       17

<PAGE>

        If you have authorized  Twentieth Century to accept written instructions
   from any one  registered  owner,  and if the  shares are owned by two or more
   persons,  only one signature is required on your written conversion  request.
   Otherwise,  the  request  should be signed by each  person in whose  name the
   shares are registered.  All signatures  should be exactly as the name appears
   in the  registration;  for example,  if an owner's name is registered as John
   Robert Jones, he should sign that way and not as John R. Jones.
        (Before writing,  read "Additional  Information  About  Conversions," on
   this page.)

   ADDITIONAL INFORMATION
   ABOUT CONVERSIONS
     (1) IN A CONVERSION FROM ONE ACCOUNT TO ANOTHER  ACCOUNT,  THE SHARES BEING
         SOLD AND THE NEW SHARES BEING PURCHASED MUST HAVE A CURRENT VALUE OF AT
         LEAST $500 AND YOU MUST MEET ANY INVESTMENT MINIMUM IMPOSED BY THE FUND
         BEING ACQUIRED.
     (2) CONVERSIONS  FROM ANY ONE FUND ACCOUNT ARE LIMITED TO FOUR TIMES IN ANY
         ONE CALENDAR YEAR except for the  conversion  of shares  pursuant to an
         automatic  monthly  conversion.  [This  limitation  will  not  apply to
         automatic  Twentieth Century College Investment Program  conversions or
         to shares held in 403(b)  accounts and certain pooled accounts owned by
         institutional investors.]
     (3) The  shares  being acquired must be qualified for sale in your state of
         residence.
     (4) If the shares are represented by a  negotiable stock  certificate,  the
         certificate must be returned before the conversion can be effected.
     (5) ONCE YOU HAVE TELEPHONED OR MAILED YOUR CONVERSION REQUEST, IT IS 
         IRREVOCABLE AND MAY NOT BE MODIFIED OR CANCELLED.
     (6) If, in any 90-day  period, the  total of  your  conversions  and  your 
         redemptions from any one account in the equity funds or  the  balanced 
         fund  exceeds  the lesser of  $250,000  or 1% of such  fund's  assets, 
         further conversions will be subject to special requirements to  comply 
         with  Twentieth  Century's  policy on large  redemptions. (See "Special
         Requirements for Large Redemptions," page 21.)
     (7) For the  purposes of  processing  conversions,  the value of the shares
         surrendered  and the  value of the  shares  acquired  are the net asset
         values of such shares next computed  after  receipt of your  conversion
         order.
     (8) Shares MAY NOT be converted unless you have furnished Twentieth Century
         with your tax  identification  number,  certified as  prescribed by the
         Internal  Revenue  Code  and  Regulations.   (See  "Tax  Identification
         Number," page 16.)
     (9) Conversion of shares is, for federal income tax purposes, a sale of the
         shares, on which you may realize a taxable gain or loss.
    (10) If the request is made by a corporation, partnership, trust, fiduciary,
         agent or  unincorporated  association,  Twentieth  Century will require
         evidence  satisfactory to it of the authority of the individual signing
         the request.
    (11) Shares of Giftrust  Investors may be con-verted only AFTER the Giftrust
         matures  because the trust is irrevocable and may not be changed in any
         way prior to its maturity.

   HOW TO REDEEM SHARES
        Twentieth  Century will buy back  ("redeem")  your shares at any time at
   the net asset value next determined after receipt of a redemption  request in
   good order.  (Before redeeming,  please read "Special  Requirements for Large
   Redemptions,"  page 21, "Additional  Information About  Redemptions," page 22
   and "When Share Price Is Determined," page 25.)


                                       18
<PAGE>

        Your  redemption  proceeds  may be delayed if you have owned your shares
   less than 15 days. (See "Redemption Proceeds," page 20.)
        ALL REQUESTS TO REDEEM  SHARES,  THE PROCEEDS OF WHICH ARE TO BE PAID BY
   CHECK,  MADE  WITHIN 30 DAYS OF OUR RECEIPT OF AN ADDRESS  CHANGE  (INCLUDING
   REQUESTS  TO REDEEM THAT  ACCOMPANY  AN ADDRESS  CHANGE)  MUST BE IN WRITING.
   ADDITIONALLY,  THE  REQUEST  MUST BE SIGNED BY EACH  PERSON IN WHOSE NAME THE
   SHARES ARE OWNED,  AND ALL  SIGNATURES  MUST BE GUARANTEED.  (See  "Signature
   Guarantee," page 20 and "How to Change Your Address of Record," page 23.)

   BY TELEPHONE
        If  you  have   authorized   Twentieth   Century  to  accept   telephone
   instructions,  you may redeem  your  shares by  telephone.  ONCE  MADE,  YOUR
   TELEPHONE REQUEST MAY NOT BE MODIFIED OR CANCELLED.
        If you call before the close of the New York Stock Exchange, usually 3
   p.m. Central time, you will receive that day's closing price. 
        (Before calling,  read "Additional  Information About Redemptions," page
   22.)

   BY MAIL
        Your  written  instructions  to redeem  shares  may be in any one of the
   following forms: 

       o A redemption form, available from Twentieth Century.
       o A letter to Twentieth Century.
       o An assignment form or stock power.
       o An endorsement on the back of your negotiable stock certificate, if you
         have one.

        ONCE MAILED TO TWENTIETH CENTURY,  THE REDEMPTION REQUEST IS IRREVOCABLE
   AND MAY NOT BE MODIFIED OR CANCELLED.
        If you have authorized  Twentieth Century to accept written instructions
   from  any one  registered  owner  without  a  signature  guarantee,  only one
   signature is required on your written  redemption  request and it need not be
   guaranteed.
        If you have NOT elected this special  service,  all  signatures  must be
   guaranteed.  (See "Signature Guarantee," page 20.) The request must be signed
   by each person in whose name the shares are registered;  for example,  in the
   case of joint ownership, each owner must sign.
        All   signatures   should  be  exactly  as  the  name   appears  in  the
   registration.  If the  owner's  name  appears  in the  registration  as  Mary
   Elizabeth Jones, she should sign that way and not as Mary E. Jones.
        (Before writing, see "Additional Information About Redemptions," page 
   22.)

   BY CHECK-A-MONTH
        Twentieth  Century's  Check-A-Month  plan  automatically  redeems enough
   shares each month to provide you with a check for a minimum of $25. To set up
   a Check-A-Month plan, call Twentieth Century for instructions.
        Shares  will be  redeemed  on the  20th  day of each  month  or the next
   business  day,  and your check will be mailed the next day.  If your  monthly
   checks  exceed the  dividends,  interest  and  capital  appreciation  on your
   shares, the payments will deplete your investment.
        Amounts  paid  to  you  by  Check-A-Month  are  not  a  return  on  your
   investment.  They are derived from the  redemption of shares in your account,
   and you must  report on your  income  tax  return  gains or  losses  that you
   realize.
        You may specify a Check-A-Month when you make your first investment.  If
   you order a Check-A-Month thereafter, then, as in any redemption, the request
   for a  Check-A-Month  or any  increase in amount must be signed by all owners
   with their signatures guaranteed unless Twentieth Century has been authorized
   to accept instructions from any one owner, by telephone or in writing without
   a signature guarantee.
        You may request that the Check-A-Month be sent to an address other than 
   the address of


                                       19

<PAGE>

   record at the time of your first investment. Thereafter, a request to send a
   Check-A-Month  to an address  other than the address of record must be signed
   by all owners, with their signatures guaranteed.
        Twentieth  Century may  terminate the Check-  A-Month at any time,  upon
   notice to you, and you likewise may  terminate it or change the amount of the
   Check-A-Month,  by notice to  Twentieth  Century in writing or by  telephone.
   Termination  or change  will  become  effective  within  five  business  days
   following receipt of your instruction.
        Your  Check-A-Month  plan may begin  anytime  after you have  owned your
   shares for 15 days.

SIGNATURE GUARANTEE
        When  a  signature  guarantee  is  required,   each  signature  MUST  be
   guaranteed by a domestic bank or trust company, credit union, broker, dealer,
   national securities exchange,
   registered securities association,  clearing agency or savings association as
   defined by federal law. The  institution  providing the guarantee  must use a
   signature  guarantee  ink  stamp  or  medallion  which  states  "Signature(s)
   Guaranteed"  and be  signed  in the name of the  guarantor  by an  authorized
   person with that person's title and the date.  Twentieth Century may reject a
   signature  guarantee if the guarantor is not a member of or  participant in a
   signature guarantee program.
        Shareholders  living abroad may acknowledge  their  signatures  before a
   U.S.   consular  officer.   Military   personnel  in  foreign  countries  may
   acknowledge   their   signatures   before   officers   authorized   to   take
   acknowledgements; e.g., legal officers and adjutants.
        Twentieth  Century may waive the signature  guarantee on a redemption of
   $5,000  or less if it is able to  verify  the  signatures  of all  registered
   owners from its account  records.  Twentieth  Century  reserves  the right to
   amend or  discontinue  this waiver  policy at any time and,  with regard to a
   particular  redemption  transaction,  to require a signature guarantee at its
   discretion.

   REDEMPTION PROCEEDS
        Redemption proceeds may be sent to you:

   BY MAIL
        If your redemption  check is mailed,  it is usually mailed on the second
   business day after  receipt of your  redemption  request,  but not later than
   seven  days  afterwards.  When a  redemption  occurs  shortly  after a recent
   purchase made by check,  Twentieth  Century may hold the redemption  proceeds
   beyond seven days but only until the purchase check clears, which may take up
   to 15 days or more. No interest is paid on the redemption  proceeds after the
   redemption and before the check is mailed. IF YOU ANTICIPATE REDEMPTIONS SOON
   AFTER YOU PURCHASE YOUR SHARES, YOU ARE ADVISED TO WIRE FUNDS TO AVOID DELAY.
        Except  for a direct  transfer  of  proceeds  from an IRA or 403(b) to a
   custodian of another IRA or 403(b),  and as noted  below,  all checks will be
   made payable to the registered owner of the shares and will be mailed only to
   the ADDRESS OF RECORD.
        If you would like a redemption  check made payable to someone other than
   the registered owner of the shares and/or mailed to an address other than the
   address of record,  your  request to redeem must (1) be made in writing;  (2)
   include an  instruction  to make the check  payable to someone other than the
   registered  owner of the shares  and/or mail it to an address  other than the
   address  of record;  and (3) be signed by all  registered  owners  with their
   signatures guaranteed. (See "Signature Guarantee," on this page.) Redemptions
   from UGMA/UTMA accounts and from certain types of retirement  accounts,  such
   as IRA, 403(b) and qualified  retirement plan accounts,  will not be eligible
   for this special  service.  If you would like to use this special service but
   are not certain that a redemption from your account is eligible,  please call
   Twentieth   Century  prior  to  submitting  your  request.   (See  "Telephone
   Services," page 22.)


                                       20

<PAGE>

   BY WIRE AND ELECTRONIC
   FUNDS TRANSFER
        You may authorize  Twentieth Century to transmit  redemption proceeds by
   wire or electronic  funds transfer.  These services will be effective 30 days
   after Twentieth Century receives the authorization.
        Proceeds from the  redemption of shares will normally be  transmitted on
   the first  business  day, but not later than the seventh day,  following  the
   date of redemption.
        Your bank usually will receive wired funds the day they are  transmitted
   or the next day. Electronically transferred funds will ordinarily be received
   within one to seven days after transmission.  Once the funds are transmitted,
   the  time of  receipt  and  the  availability  of the  funds  are not  within
   Twentieth  Century's  control.  Wired funds are subject to a charge of $10 to
   cover bank wire charges, which is deducted from redemption proceeds.
        If your  bank  account  changes,  you must  send a new  "voided"  check,
   preprinted with your bank registration, with written instructions,  including
   tax identification number. The change will be effective 30 days after receipt
   by Twentieth Century.
        Redemption  proceeds will be  transmitted  by wire or  electronic  funds
   transfer only after Twentieth  Century is satisfied that checks that paid for
   the shares have  cleared,  i.e.,  after 15 days have elapsed from the time of
   purchase,  or you have furnished  Twentieth Century with  satisfactory  proof
   that the check  has been  paid,  such as a copy of the  cancelled  check.  No
   interest is paid on the  redemption  proceeds after the redemption and before
   the funds are transmitted. IF YOU ANTICIPATE REDEMPTIONS WITHIN 15 DAYS AFTER
   YOU PURCHASE SHARES,  YOU ARE ADVISED TO WIRE FUNDS TO PAY FOR YOUR PURCHASES
   TO AVOID DELAY.

   SPECIAL REQUIREMENTS FOR
   LARGE REDEMPTIONS
        Twentieth  Century  has  elected to be  governed by Rule 18f-1 under the
   Investment  Company Act, which  obligates each fund to redeem shares in cash,
   with  respect to any one  shareholder  during any  90-day  period,  up to the
   lesser of $250,000 or 1% of the assets of the fund.  Although  redemptions in
   excess of this  limitation  will  also  normally  be paid in cash,  Twentieth
   Century  reserves the right to honor these  redemptions  by making payment in
   whole or in part in readily marketable  securities (a  "redemption-in-kind").
   If payment is made in  securities,  the  securities  will be  selected by the
   fund,  will be valued in the same manner as they are in computing  the fund's
   net asset  value and will be provided  to you in lieu of cash  without  prior
   notice.
         If you  expect to make a large  redemption  and would like to avoid any
   possibility of being paid in securities, you may do so by providing Twentieth
   Century 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.  Receipt of your  instruction  15 days prior to the
   transaction  provides the fund with  sufficient  time to raise the cash in an
   orderly manner to pay the redemption and thereby  minimizes the effect of the
   redemption on the fund and its remaining shareholders.
         Despite its right to redeem fund shares  through a  redemption-in-kind,
   Twentieth  Century does not expect to exercise  this option unless a fund has
   an unusually  low level of cash to meet  redemptions  and/or is  experiencing
   unusually  strong  demands for its cash.  Such a demand might be caused,  for
   example, by extreme market conditions that result in an abnormally high level
   of redemption  requests  concentrated in a short period of time. Absent these
   or similar circumstances,  Twentieth Century expects redemptions in excess of
   $250,000  to be paid in cash in any fund with assets of more than $50 million
   if total  redemptions from any one account in any 90-day period do not exceed
   one-half of 1% of the total assets of the fund.


                                       21

<PAGE>

   AUTOMATIC REDEMPTION OF SHARES
        If at any time you have a fund account  (other than Giftrust) that falls
   into either of the following categories:

        (i) you invested the required minimum initial  investment amount for the
        fund,  currently  $2,500  ($1,000 for  UGMA/UTMA  accounts),  but due to
        conversions or redemptions you have made, the account now has a value of
        less than the minimum initial investment amount; or

        (ii) you have not invested the minimum initial  investment amount, and a
        $50 or greater  automatic  monthly  investment  to  purchase  additional
        shares does not exist for the account;

   a  notification  will be sent  advising  you of the  need to  either  make an
   investment  to bring the value of the  shares  held in the  account up to the
   minimum initial  investment amount or to establish a $50 or greater automatic
   monthly  investment to purchase  additional  shares. If the investment is not
   made or the automatic  monthly  investment is not established  within 60 days
   from the date of  notification,  the shares held in the fund  account will be
   redeemed and the proceeds from the  redemption  will be sent by check to your
   address of record.
        The automatic redemption of shares will not apply to Giftrust Investors,
   College  Investment  Program accounts in the rebalancing  phase,  Indivi-dual
   Retirement  Accounts,   403(b)  accounts  and  other  types  of  tax-deferred
   retirement plan accounts.  In addition,  Twentieth Century reserves the right
   to modify its policies  regarding the automatic  redemption of shares,  or to
   waive such policies in whole or in part for certain classes of investors.

   ADDITIONAL INFORMATION
   ABOUT REDEMPTIONS
        If you  experience  difficulty in making a telephone  redemption  during
   periods of drastic economic or market changes, your redemption request may be
   made by regular  or express  mail.  It will be  implemented  at the net asset
   value next  determined  after your  request has been  received  by  Twentieth
   Century in good  order.  Twentieth  Century  reserves  the right to revise or
   terminate the telephone redemption privilege at any time.
        REDEMPTIONS  SPECIFYING  A CERTAIN  DATE OR PRICE CANNOT BE ACCEPTED AND
   WILL BE RETURNED.
        If the shares are  represented by a negotiable  stock  certificate,  the
   certificate must be returned before the redemption can be effected.
        ALL REDEMPTIONS ARE MADE AND THE PRICE IS DETERMINED ON THE DAY WHEN ALL
   DOCUMENTATION,  PROPERLY  COMPLETED,  IS RECEIVED BY TWENTIETH CENTURY.  (See
   "When Share Price Is Determined," page 25.)
        Until a Giftrust  matures,  only the independent  trustee,  as the legal
   owner of the  shares,  may redeem  them.  The ability of the  beneficiary  to
   compel  the  trustee  to redeem  the  shares is  subject  to the terms of the
   Giftrust.
        If a request  to redeem is made by a  corporation,  partnership,  trust,
   fiduciary,  agent,  or  unincorporated  association,  Twentieth  Century will
   require  evidence  satisfactory  to it of the  authority  of  the  individual
   signing  the  request.  Please  call or write  Twentieth  Century for further
   information.
        A request to redeem shares in an IRA or 403(b) plan must be  accompanied
   by an IRS Form W-4P and a reason for withdrawal as specified by the IRS.

        You may notify  Twentieth  Century of changes in your  address of record
   either by writing us or calling our Investors  Line.  Because your address of
   record  impacts every piece of  information  we send to you, you are urged to
   notify us  promptly of any change of  address.  TO PROTECT YOU AND  TWENTIETH
   CENTURY,  ALL REQUESTS TO REDEEM SHARES, THE PROCEEDS OF WHICH ARE TO BE PAID
   BY CHECK,  MADE WITHIN 30 DAYS OF OUR RECEIPT OF AN ADDRESS CHANGE (INCLUDING
   REQUESTS TO REDEEM THAT ACCOMPANY AN ADDRESS CHANGE) MUST BE MADE IN WRITING,
   SIGNED BY EACH PERSON IN WHOSE NAME THE SHARES ARE OWNED,  AND ALL SIGNATURES
   MUST BE GUARANTEED. (See "Signature Guarantee," page 20.)

   TAX-QUALIFIED RETIREMENT PLANS
        Twentieth Century's funds are available for your tax-deferred retirement
   plan. Call or write Twentieth Century and request the appropriate forms for:

       o Individual Retirement Accounts (IRAs).
       o 403(b) plans for employees of public school systems and non-profit 
         organizations.
       o Profit sharing plans and pension plans for corporations and other 
         employers.

   HOW TO TRANSFER AN INVESTMENT
   TO A TWENTIETH CENTURY
   RETIREMENT PLAN
        It is easy to transfer your  tax-deferred plan to Twentieth Century from
   another company or custodian.  Call or write Twentieth  Century for a Request
   to Transfer form.
        If you direct  Twentieth  Century  to  transfer  funds from an  existing
   non-retirement  Twentieth  Century  account  into a retirement  account,  the
   shares  in your  non-retirement  account  will be  redeemed.  The  redemption
   proceeds   will  be  invested  in  your   Twentieth   Century  IRA  or  other
   tax-qualified retirement plan. The redemption is a taxable event resulting in
   a taxable gain or loss.

   COLLEGE INVESTMENT PROGRAM
        Through  this  special  service,  you can  sys-tematically  invest for a
   child's college education.  You may make automatic monthly investments in any
   amount  you choose  (minimum  of $50) in shares of Select  Investors.  As the
   child nears  college age, or another age you select,  Twentieth  Century will
   automatically   begin   reallocating  a  predetermined   percentage  of  your
   investment


                                       23

<PAGE>

   from shares of Select  Investors  to shares of our money  market  fund,  Cash
   Reserve.  (See  Twentieth  Century's  Fixed  Income  Funds  Prospectus.)  The
   percentage of your investment that will be reallocated is based on the number
   of years  over  which  you want the  reallocation  to occur.  Call  Twentieth
   Century for additional information about this service.

   HOW TO TRANSFER YOUR SHARES
   TO ANOTHER PERSON
        You  may  transfer  ownership  of  your  shares  to  another  person  or
   organization  by written  instructions  to Twentieth  Century,  SIGNED BY ALL
   OWNERS  AND  WITH  SIGNATURES   GUARANTEED  AS  DESCRIBED  UNDER   "SIGNATURE
   GUARANTEE,"  PAGE 20. IF THE SHARES ARE  REPRESENTED  BY A  NEGOTIABLE  STOCK
   CERTIFICATE,   THE   CERTIFICATE   MUST  BE  RETURNED   WITH  YOUR   TRANSFER
   INSTRUCTIONS.

   REPORTS TO SHAREHOLDERS
        In January of each year, Twentieth Century will send shareholders in the
   common  stock  funds a  cumulative  statement  of their  account  showing all
   transactions  since the beginning of the previous year.  Shareholders  in the
   balanced fund will receive such statements,  including dividend  information,
   at the end of each  calendar  quarter.  You may request a  statement  of your
   account activity at any time.
        Each time you  invest,  redeem,  transfer or convert  shares,  Twentieth
   Century will send you a confirmation of the transaction. Carefully review all
   the information  relating to the transaction to ensure that your  instruction
   was acted on properly. Please notify Twentieth Century immediately in writing
   if there is an error. If you fail to provide  notification of an error within
   30  days of the  transaction,  you  will  be  deemed  to  have  ratified  the
   transaction.
        No later than January 31 of each year,  Twentieth  Century will send you
   the following  reports,  which you may use in completing your U.S. income tax
   return:

        Form 1099-DIV  Reports taxable distributions during the preceding year.
                       (If you did not receive taxable distributions in the  
                       previous year, you will not receive a 1099-DIV.)
        Form 1099-B    Reports proceeds paid on redemptions during the preceding
                       year.
        Form 1099-R    Reports  distributions  from IRAs and 403(b) plans during
                       the preceding year. 

        At such time as  prescribed  by law,  Twentieth  Century will send you a
   Form 5498, which reports  contributions to your IRA for the previous calendar
   year.
        In  December  of each year,  Twentieth  Century  will send you an annual
   report that includes audited financial  statements for the fiscal year ending
   the preceding  October 31 and a list of securities in its  portfolios on that
   date.  In June of each year,  Twentieth  Century  will send you a  semiannual
   report that includes unaudited financial statements for the six months ending
   the preceding  April 30, as well as a list of securities in its portfolios on
   that date.  Twentieth  Century  does not publish  interim  lists of portfolio
   securities.
        Twentieth  Century usually  prepares a new prospectus on March 1 of each
   year. You will receive a current  prospectus  with the  confirmation  of your
   first investment after that date.
        Each year that an annual  meeting  is held you will  receive a notice of
   the annual meeting of shareholders  (and of special  meetings,  if any) and a
   proxy statement.
        BECAUSE  TWENTIETH CENTURY NEEDS YOUR VOTE TO CONDUCT ITS ANNUAL MEETING
   OF SHAREHOLDERS, YOU ARE URGED TO RETURN YOUR PROXY.
        IT IS IMPORTANT THAT YOU NOTIFY TWENTIETH CENTURY PROMPTLY OF ANY CHANGE
   OF ADDRESS. (See "How to Change Your Address of Record," page 23.)

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

   SHARE PRICE

   WHEN SHARE PRICE IS DETERMINED
        The price of your shares is their net asset value next determined  after
   receipt of your instruction to purchase,  convert or redeem.  Net asset value
   is determined by calculating  the total value of a fund's  assets,  deducting
   total   liabilities   and  dividing  the  result  by  the  number  of  shares
   outstanding.  Net  asset  value is  determined  on each day that the New York
   Stock Exchange is open.
        Investments  and requests to redeem  shares will receive the share price
   next  determined  after  receipt by Twentieth  Century of the  investment  or
   redemption  request.  For example,  investments and requests to redeem shares
   received by  Twentieth  Century  before the close of business on the New York
   Stock Exchange are effective on, and will receive the price determined,  that
   day as of the close of the Exchange.  Redemption requests received thereafter
   are  effective  on, and receive the price  determined  as of the close of the
   Exchange on, the next day the Exchange is open.
        Investments are considered  received only when your check or wired funds
   are received by Twentieth Century. Wired funds are considered received on the
   day they are  deposited  in  Twentieth  Century's  bank  account  if they are
   deposited  before  the  close of  business  on the  Exchange,  usually 3 p.m.
   Central time.
        Investments  by  telephone  pursuant  to  your  prior  authorization  to
   Twentieth Century to draw on your bank account are considered received at the
   time of your telephone call.
        Investment and transaction instructions received by Twentieth Century on
   any  business day by mail at its office prior to the close of business on the
   Exchange,  usually 3 p.m.  Central  time,  will  receive  that  day's  price.
   Investments and instructions received after that time, will receive the price
   determined on the next business day.

   HOW SHARE PRICE IS DETERMINED
        The  valuation  of  assets  for  determining  net  asset  value  may  be
   summarized as follows:
        The portfolio securities of each fund, except as otherwise noted, listed
   or traded on a domestic securities exchange are valued at the last sale price
   on that  exchange.  If no sale is  reported,  the mean of the  latest bid and
   asked  price  is used.  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 good faith 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.
        Pursuant to a  determination  by Twentieth  Century's board of directors
   that such value represents fair value,  debt securities with maturities of 60
   days or less are  valued at  amortized  cost.  When a  security  is valued at
   amortized  cost, it is valued at its cost when  purchased,  and thereafter by
   assuming a constant  amortization  to  maturity  of any  discount or premium,
   regardless of the impact of fluctuating interest rates on the market value of
   the instrument.
        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,
   usually 3 p.m. Central time, if that is earlier. That value is then converted
   to dollars at the prevailing foreign exchange rate.


                                       25

<PAGE>

        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  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 a 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 a fund's  portfolio  may be  affected on days when shares of the
   fund may not be purchased or redeemed.

   WHERE TO FIND INFORMATION
   ABOUT SHARE PRICE
        The net asset  values of  Twentieth  Century's  funds are  published  in
   leading  newspapers  daily.  The net asset  values  may also be  obtained  by
   calling Twentieth Century. (See "Telephone Services," page 22.)

   DISTRIBUTIONS
        In general,  distributions  from net investment  income and net realized
   securities  gains,  if any, are declared and paid once a year,  but the funds
   may  make  distributions  on  a  more  frequent  basis  to  comply  with  the
   distribution  requirements  of the Internal  Revenue Code, in all events in a
   manner consistent with the provisions of the Investment Company Act.

   EQUITY FUNDS
        Distributions  from investment  income and from net profits  realized on
   the sale of  securities,  if any,  will be  declared  annually  on or  before
   December 31.
        THE  OBJECTIVE  OF  THESE  FUNDS  IS  CAPITAL  APPRECIATION  AND NOT THE
   PRODUCTION OF DIS-TRIBUTIONS.  YOU MAY MEASURE THE SUCCESS OF YOUR INVESTMENT
   BY  THE  VALUE  OF  YOUR  INVESTMENT  AT  ANY  GIVEN  TIME  AND  NOT  BY  THE
   DISTRIBUTIONS YOU RECEIVE. 

   BALANCED FUND
        Distributions  from  investment  income will be paid quarterly in March,
   June, September and December.  Distributions from net profits realized on the
   sale of securities, if any, will be paid annually on or before December 31.

   GENERAL INFORMATION
   ABOUT DISTRIBUTIONS
        Distributions  will be  reinvested  unless you elect to receive  them in
   cash.  Distributions  of less than $10 and  distributions on shares purchased
   within  the  last 15  days,  however,  will  not be paid in cash  and will be
   reinvested.  You may elect to have distributions on shares held in Individual
   Retirement  Accounts  and  403(b)  plans  paid in cash only if you are 59 1/2
   years old or permanently  and totally  disabled.  Distributions  on shares of
   Giftrust accounts will not be paid in cash and will be reinvested.
   Distribution  checks  normally are mailed  within seven days after the record
   date.
        The board of  directors  may elect not to  distribute  capital  gains in
   whole or in part to take advantage of loss carryovers.
        A  distribution  on shares of a fund does not increase the value of your
   shares  or your  total  return.  At any given  time the value of your  shares
   includes the  undistributed  net gains,  if any,  realized by the fund on the
   sale of  portfolio  securities,  and  undistributed  dividends  and  interest
   received, less fund expenses.


                                       26

<PAGE>

        Because  such  gains and  dividends  are  included  in the value of your
   shares,  when they are distributed the value of your shares is reduced by the
   amount  of  the  distribution.  If  you  buy  your  shares  just  before  the
   distribution, you will pay the full price for your shares, and then receive a
   portion of the purchase price back as a taxable  distribution.  (See "Taxes,"
   on this page.)
        If  your   distribution   is  reinvested  in  additional   shares,   the
   distribution  has no effect on the  value of your  investment;  while you own
   more  shares,  the value of each share has been  reduced by the amount of the
   distribution.  Likewise,  if you take your distribution in cash, the value of
   your  shares  after the record  date plus the cash  received  is equal to the
   value of the shares  before the record  date.  For  example,  if your  shares
   immediately  before the  distribution  have a value of $10,  including  $2 in
   dividends and capital gains  realized by the fund during the year, and if the
   $2 is  distributed,  the value will decline to $8. If the $2 is reinvested at
   $8 per share, you will receive .250 shares,  so that, after the distribution,
   you will have 1.250 shares at $8 per share, or $10, the same as before.

   TAXES
        Twentieth  Century  has elected to be taxed  under  Subchapter  M of the
   Internal  Revenue  Code,  which  means  that  to the  extent  its  income  is
   distributed to shareholders it pays no income tax.
        Distributions of net investment income and net short-term  capital gains
   are  taxable to you as  ordinary  income.  Distributions  from net  long-term
   capital gains are taxable as long-term capital gains regardless of the length
   of time you have  held the  shares  on which  such  distributions  are  paid.
   However,  you should note that any loss  realized upon the sale or redemption
   of shares held for six months or less will be treated as a long-term  capital
   loss to the extent of any distribution of long-term  capital gain to you with
   respect to such shares.
        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  of  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.
        If a fund purchases the securities of certain foreign  investment  funds
   or trusts called passive foreign investment  companies,  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 may also 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.
        Distributions are taxable to you regardless of whether they are taken in
   cash or  reinvested,  even if the value of your shares is below your cost. If
   you purchase shares shortly before a distribution,  you must pay income taxes
   on the  distribution,  even  though the value of your  investment  (plus cash
   received, if any) remains the same. In addition,  the share price at the time
   you purchase  shares may include  unrealized  gains in the securities held in
   the  investment  portfolio of the fund.  If these  portfolio  securities  are
   subsequently sold and the gains are realized, they will,


        
                                       27
       
<PAGE>

    to the extent not offset by capital losses, be paid to you as a distribution
   of  capital  gains and will be  taxable  to you as  short-term  or  long-term
   capital gains. (See "General Information About Distributions," on page 26.)
        In January of the year  following the  distribution,  Twentieth  Century
   will  send  you  a  Form  1099-DIV  notifying  you  of  the  status  of  your
   distributions for federal income tax purposes.
        Distributions  may also be subject to state and local taxes, even if all
   or a substantial part of such distributions are derived from interest on U.S.
   government obligations which, if you received them directly,  would be exempt
   from  state  income  tax.  However,  most but not all  states  allow this tax
   exemption to pass through to fund shareholders when a fund pays distributions
   to its shareholders. You should consult your tax adviser about the tax status
   of such distributions in your own state.
        If you have not complied with certain provisions of the Internal Revenue
   Code and  Regulations,  Twentieth  Century  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 TWENTIETH
   CENTURY THAT OMIT YOUR SOCIAL  SECURITY NUMBER OR TAX  IDENTIFICATION  NUMBER
   WILL  SUBJECT  TWENTIETH  CENTURY 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.  (See "Tax  Identification  Number,"
   page 16.)
        Redemption of shares of a fund 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.  Assuming that  shareholders  hold such shares as a capital
   asset,  the gain or loss will be a capital gain or loss and will generally be
   long term if shareholders have held such shares for a period of more than one
   year.  If  a  loss  is  realized  on  the  redemption  of  fund  shares,  the
   reinvestment  in  additional  fund shares  within 30 days before or after the
   redemption may be subject to the "wash sale" rules of the Code,  resulting in
   a  postponement  of the  recognition  of such  loss for  federal  income  tax
   purposes.

   A TAX NOTE ABOUT GIFTRUST
        Because it is a gift of a future  interest,  an investment in a Giftrust
   does not qualify for the annual gift tax exclusion of $10,000.  If you give a
   Giftrust,  you  must  file a  United  States  Gift  Tax  Return.  If you make
   additional  investments in subsequent  years, a Gift Tax Return must be filed
   for each year's  gift.  No gift tax is payable  until your  cumulative  gifts
   exceed the exemption equivalent of $600,000.  The gift is applied against the
   exemption equivalent that would otherwise be available in the future.
        The income of the  Giftrust is exempt from  federal  income tax until it
   exceeds $100; the trustee of the Giftrust  files federal and Missouri  income
   tax  returns  and pays the income  tax out of the  assets of the  trust.  The
   distribution  to the  beneficiary  at the  maturity  of the  Giftrust  may be
   subject to the throwback rules under the Internal Revenue Code. The throwback
   rules may create  additional tax liability for a beneficiary who is age 21 or
   older at the time the  Giftrust  matures.  More  than one  trust for the same
   beneficiary  may be subject to the  provisions  of the Internal  Revenue Code
   with respect to multiple trusts.
         The tax laws  applicable  to trusts in general are quite  complex.  You
   should  consider  consulting  your tax  adviser  before  opening  a  Giftrust
   account.

   MANAGEMENT
        Under  the laws of the State of  Maryland,  the  board of  directors  is
   responsible for managing the business and affairs of Twentieth Century.

<PAGE>

   Acting  pursuant  to an  investment  advisory  agreement  entered  into with
   Twentieth Century,  Investors  Research  Corporation  ("Investors  Research")
   serves as the investment manager of Twentieth Century. Its principal place of
   business is Twentieth Century Tower, 4500 Main Street,  Kansas City, Missouri
   64111.  Investors Research has been providing investment advisory services to
   Twentieth Century since it was founded in 1958.
        Investors Research  supervises and manages the investment  portfolios of
   Twentieth  Century  and  directs  the  purchase  and  sale of its  investment
   securities.   Investors  Research  utilizes  teams  of  portfolio   managers,
   assistant  portfolio  managers  and  analysts  acting  together to manage the
   assets of the funds.  The teams meet regularly to review  portfolio  holdings
   and to discuss  purchase and sale activity.  The teams adjust holdings in the
   funds'  portfolios  as  they  deem  appropriate  in  pursuit  of  the  funds'
   investment  objectives.  Individual portfolio manager members of the team may
   also  adjust  portfolio  holdings  of the  funds as  necessary  between  team
   meetings.
        The portfolio  manager members of the teams managing the funds described

        The  activities of Investors  Research are subject only to directions of
   Twentieth  Century's  board of  directors.  Investors  Research  pays all the
   expenses of Twentieth Century except  brokerage,  taxes,  interest,  fees and
   expenses of the non-interested  person directors (including counsel fees) and
   extraordinary expenses.
        For the  services  provided to  Twentieth  Century,  Investors  Research
   receives  an annual fee of 1% of the  average  net  assets of each  series of
   shares offered by this  prospectus.  On the first business day of each month,
   each series of shares pays a  management  fee to the manager for the previous
   month at the rate specified.  The fee for the previous month is calculated by
   multiplying the applicable fee for such series by the aggregate average daily
   closing  value of the  series'  net assets  during the  previous  month,  and
   further multiplying that product 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  fees paid by the  funds to  Investors  Research  may be
   higher than that paid by many investment companies.  However, most if not all
   of such companies also pay in addition  certain of their own expenses,  while
   virtually all of Twentieth  Century's  expenses except as specified above are
   paid by Investors Research.
        Twentieth  Century  Services,  Inc.,  4500  Main  Street,  Kansas  City,
   Missouri  64111,  acts  as  transfer  agent  and  dividend-paying  agent  for
   Twentieth  Century.  It  provides  facilities,  equipment  and  personnel  to
   Twentieth  Century,  and is paid for such  services  by  Investors  Research.
   Certain  record-keeping   services  that  would  otherwise  be  performed  by
   Twentieth Century Services, Inc., may be performed by an insurance company or
   other entity providing  similar  services for various  retirement plans using
   shares of  Twentieth  Century as a funding  medium or by broker  dealers  for
   their customers investing in shares of Twentieth Century.  Investors Research
   may elect to enter into a contract to pay them for such services.
        From time to time,  special  services may be offered to shareholders who
   maintain  higher share balances in the funds.  These services may include the
   waiver  of  minimum  investment   requirements,   expedited  confirmation  of
   shareholder transactions, newsletters and a team of personal representatives.
   Any expenses associated with these special services will be paid by Investors
   Research.
        Investors Research and Twentieth Century Services,  Inc. are both wholly
   owned by Twentieth Century Companies,  Inc. James E. Stowers Jr., chairman of
   the  board  of  Twentieth  Century  Investors,   controls  Twentieth  Century
   Companies by virtue of his ownership of a majority of its common stock.

   FURTHER INFORMATION
   ABOUT TWENTIETH CENTURY
        Twentieth   Century   Investors,   Inc.  was  organized  as  a  Maryland
   corporation on July 2, 1990. The corporation commenced operations on February
   28, 1991, the date it merged with


                                       30

<PAGE>

   Twentieth Century Investors,  Inc., a Delaware corporation which had been in
   business since October 1958.  Pursuant to the terms of the Agreement and Plan
   of Merger dated July 27, 1990,  the Maryland  corporation  was the  surviving
   entity and continued the business of the Delaware  corporation  with the same
   officers  and  directors,  the  same  shareholders  and the  same  investment
   objectives, policies and restrictions.
        Twentieth  Century  is a  diversified,  open-end  management  investment
   company   whose  shares  are   presently   held  by  more  than  1.5  million
   shareholders.  Its business and affairs are managed by its officers under the
   direction of its board of directors.
        The principal  office of Twentieth  Century is Twentieth  Century Tower,
   4500 Main Street,  P.O. Box 419200,  Kansas City,  Missouri  64141-6200.  All
   inquiries may be made by mail to that address, or by phone to 1-800-345-2021.
   (For local Kansas City area or international callers: 816-531-5575.)
        Twentieth Century issues 16 series of $.01 par value shares.  The assets
   belonging to each series of shares are held separately by the custodian,  and
   in effect each series is a separate fund.
        Each  share,  irrespective  of series,  is entitled to one vote for each
   dollar of net asset value  applicable to such share on all questions,  except
   for those  matters  which must be voted on separately by the series of shares
   affected.  Matters  affecting  only one  series  are voted  upon only by that
   series.
        Shares have non-cumulative  voting rights,  which means that the holders
   of more than 50% of the shares voting for the election of directors can elect
   all of the  directors  if they choose to do so, and in such event the holders
   of the  remaining  less-than-50%  of the shares will not be able to elect any
   person  or  persons  to  the  board  of  directors.  
        Unless required by the Investment  Company Act, it will not be necessary
   for Twentieth  Century to hold annual meetings of shareholders.  As a result,
   shareholders  may not vote  each year on the  election  of  directors  or the
   appointment of auditors.  However,  pursuant to Twentieth  Century's by-laws,
   the holders of shares  representing  at least 10% of the votes entitled to be

                     SUPPLEMENT TO INSTITUTIONAL PROSPECTUS

                        Supplement dated January 2, 1996

                         Prospectus dated March 1, 1995

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

     The disclosure  set forth below  replaces the first  paragraph on page 2 of
the Institutional Prospectus:
     SELECT  INVESTORS AND HERITAGE  INVESTORS  seek capital  growth.  The funds
intend to pursue their  investment  objectives by investing  primarily in common
stocks   of   companies    that   are   considered   by   management   to   have
better-than-average  prospects  for  appreciation.  As a matter  of  fundamental
policy,  80% of the assets of Select Investors and of Heritage Investors must be
invested in  securities of companies  that have a record of paying  dividends or
have  committed  themselves  to the payment of regular  dividends,  or otherwise
produce income.

     The  following  paragraph  replaces the first  paragraph  under the heading
"Select  Investors,   Heritage   Investors"  on  page  9  of  the  Institutional
Prospectus:
     Securities of companies chosen for Select Investors and Heritage  Investors
are chosen primarily for their growth  potential.  Additionally,  as a matter of
fundamental  policy,  80% of the  assets of  Select  Investors  and of  Heritage
Investors  must be invested in  securities  of  companies  that have a record of
paying  dividends  or  have  committed  themselves  to the  payment  of  regular
dividends or otherwise  produce income.  The remaining 20% of fund assets may be
invested in any otherwise permissible  securities that the manager believes will
contribute to the funds' stated  investment  objectives.  The income payments of
equity  securities  chosen are only a secondary  consideration;  therefore,  the
income  return  that  Select  and  Heritage  provide  may  not  be  significant.
Otherwise,  Select and Heritage follow the same investment  techniques described
below for Growth, Ultra and Vista.

     The  following  paragraph  replaces the third  paragraph  under the heading
"Select  Investors,   Heritage   Investors"  on  page  9  of  the  Institutional
Prospectus:
     Because of its size,  and because it invests  primarily in securities  that
pay  dividends  or are  committed  to the  payment of  dividends,  Select may be
expected to be the least  volatile of the common  stock funds  described in this
prospectus.

     The disclosure set forth below modifies the section "Management"  beginning
on page 24 of the Institutional  Prospectus. A new subheading titled "Investment
Management" is hereby added immediately  below the heading  "Management" on page
24. The following paragraph is added after the first paragraph on page 25.
     In June 1995,  Twentieth Century  Companies,  Inc.  ("TCC"),  the parent of
Investors  Research,  acquired  Benham  Management  International,  Inc.  In the
acquisition,  Benham Management  Corporation  ("BMC"), the investment adviser to
the Benham  Group of Mutual  Funds,  became a wholly  owned  subsidiary  of TCC.
Certain  employees of BMC will be providing  investment  management  services to
Twentieth  Century  funds,  while certain  Twentieth  Century  employees will be
providing investment management services to Benham funds.


<PAGE>

     The following two paragraphs are added after the first paragraph on page 26
of the Institutional Prospectus.
     DAVID W. SCHROEDER joined Benham in 1990. He currently  maintains principal
management  responsibility  for nine Benham funds.  Mr. Schroeder is a member of
the  team  that  manages  U.S.  Governments   Short-Term  and  U.S.  Governments
Intermediate-Term.
     AMY  O'DONNELL  joined  Benham in 1987,  becoming a member of its portfolio
department  in 1988.  In 1992 she assumed  her  current  position as a portfolio
manager of three  Benham  funds.  She is a member of the team that  manages Cash
Reserve.

     The following two paragraphs replace the sixth paragraph  appearing on page
26 of the Institutional Prospectus.

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

TRANSFER AND ADMINISTRATIVE SERVICES
     Twentieth Century Services,  Inc., 4500 Main Street,  Kansas City, Missouri
64111, acts as transfer,  administrative  services and dividend-paying agent for
Twentieth Century. It provides facilities,  equipment and personnel to Twentieth
Century,  and  is  paid  for  such  services  by  Investors  Research.   Certain
record-keeping  services that would otherwise be performed by Twentieth  Century
Services,  Inc.,  may be  performed  by an  insurance  company  or other  entity
providing  similar  services  for  various  retirement  plans  using  shares  of
Twentieth Century as a funding medium or by  broker-dealers  for their customers
investing in shares of Twentieth Century.  Investors Research may elect to enter
into a contract to pay them for such services.

                         INFORMATION REGARDING THE FUNDS
- --------------------------------------------------------------------------------

INFORMATION ABOUT INVESTMENT
POLICIES OF THE FUNDS
       Twentieth Century has adopted certain investment  restrictions applicable
  to the funds that are set forth in the  statement of  additional  information.
  Those  restrictions,  as  well  as the  investment  objectives  of the  funds,
  identified  on the inside front cover page of this  prospectus,  and any other
  investment  policies  designated as "fundamental" in this prospectus or in the
  statement of additional  information,  cannot be changed  without  shareholder
  approval.  The funds  have  implemented  additional  investment  policies  and
  practices  to guide  their  activities  in the  pursuit  of  their  respective
  investment  objectives.  These  policies and  practices,  which are  described
  throughout this prospectus, are not designated as fundamental policies and may
  be changed without shareholder approval.
       The descriptions that follow are designed
  to help you choose the fund that best fits your investment objectives. You may
  want to pursue more than one  objective by investing in more than one of these
  funds.

  EQUITY FUNDS
       All of Twentieth  Century's  equity  funds and the equity  portion of the
  portfolio  of  Balanced   Investors   seek  capital  growth  by  investing  in
  securities,  primarily  common  stocks,  that  meet  certain  fundamental  and
  technical  standards  of  selection  and have,  in the  opinion  of  Twentieth
  Century's management,  better-than-average potential for appreciation. So long
  as a sufficient  number of such  securities  is available,  Twentieth  Century
  intends to stay fully invested in these securities  regardless of the movement
  of stock prices generally.  In most circumstances,  the funds' actual level of
  cash and cash  equivalents  will fluctuate  between 0% and 10% of total assets
  with 90% to 100% of its  assets  committed  to equity  and  equity  equivalent
  investments.  The funds may purchase  securities only of companies that have a
  record of at least three years continuous operation.

  SELECT INVESTORS
  HERITAGE INVESTORS
       Securities  of  companies  chosen for Select and Heritage  Investors  are
  chosen  primarily  for their growth  potential.  Additionally,  as a matter of
  fundamental  policy,  the companies must have a record of paying, or must have
  committed  themselves  to the  payment of,  regular  dividends.  Their  income
  payments are only a secondary consideration; therefore, the income return that
  Select and Heritage  provide may not be  significant.  Other-wise,  Select and
  Heritage  follow the same  investment  techniques  described below for Growth,
  Ultra and Vista.
       Since  Select is one of the  largest  of  Twentieth  Century's  funds and
  Heritage  is  substantially  smaller,  Select  will invest in shares of larger
  companies with larger share trading  volume,  and Heritage will tend to invest
  in smaller companies with smaller share trading volume. However, the two funds
  are not mutually  exclusive,  and a given security may be owned by both funds.
  For the  reasons  stated  below  under the  caption  "Growth,  Ultra and Vista
  Investors,"  it should be expected  that  Heritage  will be more  volatile and
  subject to greater short-term risk and long-term opportunity than Select.
       Because of its size,  and because it can invest only in  securities  that
  pay  dividends  or are  committed to the payment of  dividends,  Select may be
  expected to be the least volatile of the common stock funds  described in this
  prospectus.

  GROWTH INVESTORS
  ULTRA INVESTORS
  VISTA INVESTORS
       Management  selects,  for the  portfolios  of  Growth,  Ultra and  Vista,
  securities of companies  whose earnings and revenue  trends meet  management's
  standards of  selection.  They then  determine to which of the three funds the
  selected securities would most contribute.
       Large,   established   companies  are  generally   allocated  to  Growth.
  Medium-sized and smaller


                                        9

<PAGE>

  companies are allocated to Ultra and Vista.  As of February 1, 1995,  the size
  of the companies (as reflected by their  capitalizations) held by the funds is
  as follows:

                                            Median Capitalization
                                              of Companies Held
================================================================================
  Growth Investors                              $7,658,739,000
  Ultra Investors                               $1,946,368,000
  Vista Investors                               $  623,861,000
================================================================================

       The median  capitalization  of the  companies  in a given fund may change
  over  time.  In  addition,  the  criteria  outlined  above  are  not  mutually
  exclusive, and a given security may be owned by more than one of the funds.
       The size of the fund and of its  portfolio  companies  tends to give each
  fund its own  characteristics  of volatility and risk. These  differences come
  about because developments such as new or improved products or methods,  which
  would be relatively  insignificant  to a large portfolio  company,  may have a
  substantial  impact on the earnings and revenues of a small company and create
  a greater  demand and a higher value  forits  shares.  However,  a new product
  failure which could readily be absorbed by a large portfolio company can cause
  a rapid  decline in the value of the shares of a smaller  company.  Hence,  it
  could be expected  that funds  investing  in smaller  companies  would be more
  volatile than funds investing in larger companies.

  BALANCED FUND

  BALANCED INVESTORS
       Balanced Investors seeks capital growth and current income.  Selection of
  securities for the equity portion of its portfolio is discussed  under "Equity
  Funds," page 9.
       Since a portion of the fund's  portfolio will be invested in fixed income
  securities,  the  opportunity for capital  appreciation  may be expected to be
  less than with  Twentieth  Century's  funds that  invest  primarily  in common
  stocks.
       Management intends to maintain  approximately 40% of the fund's assets in
  fixed income  securities  with a minimum of 25% of that amount in fixed income
  senior  securities.  The fixed  income  securities  in the fund will be chosen
  based on their level of income  production and price  stability.  The fund may
  invest in a  diversified  portfolio  of debt and other  fixed-rate  securities
  payable in United States currency. These may include obligations of the United
  States government,  its agencies and  instrumentalities;  corporate securities
  (bonds,  notes,  preferreds and convertible issues), and sovereign government,
  municipal, mortgage-backed and other asset-backed securities.
       There are no maturity  restrictions  on the fixed  income  securities  in
  which the fund invests.  Under normal market  conditions the weighted  average
  portfolio maturity will be in the three- to 10-year range. The management will
  actively  manage the  portfolio,  adjusting  the  weighted  average  portfolio
  maturity  in response to expected  interest  rates.  During  periods of rising
  interest rates, a shorter weighted average maturity may be adopted in order to
  reduce the effect of bond price  declines on the fund's net asset value.  When
  interest rates are falling and bond prices rising,  a longer weighted  average
  portfolio maturity may be adopted.
       It is  management's  intention to invest the fund's fixed income holdings
  in high-grade securities. At least 80% of fixed income assets will be invested
  in securities which at the time of purchase are rated within the three highest
  categories by a nationally  recognized  statistical  rating  organization  [at
  least A by Moody's  Investors  Service,  Inc.  (Moody's)  or Standard & Poor's
  Corp.
  (S&P)].
       The  remaining  portion of the fixed  income  assets may be  invested  in
  issues in the fourth  highest  category (Baa by Moody's or BBB by S&P), or, if
  not  rated,  are  of  equivalent  investment  quality  as  determined  by  the
  management  and  which,   in  the  opinion  of   management,   can  contribute
  meaningfully to the fund's results without  compromising its objectives.  Such
  issues  might  include  a  lower-rated   issue  where  research  suggests  the
  likelihood of a rating


                                       10

<PAGE>

  increase;  or a convertible issue of a company deemed attractive by the equity
  management  team.  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  or
  changing circumstances. (See "Fundamentals of Fixed Income Investing," page 13
  and "An  Explanation of Fixed Income  Securities  Ratings" in the statement of
  additional information.)


  FIXED INCOME FUNDS
       For  an  explanation  of  the  securities  ratings  referred  to  in  the
  discussion  of our fixed income  funds,  see "An  Explanation  of Fixed Income
  Securities Ratings" in the statement of additional information.


  CASH RESERVE
       Cash Reserve seeks to obtain a level of current  income  consistent  with
  preservation of capital and maintenance of liquidity. Cash Reserve is designed
  for investors who want income and no fluctuation in their principal.
       Cash  Reserve  expects,  but cannot  guarantee,  that it will  maintain a
  constant share price of $1.00. The fund follows  industry-standard  guidelines
  on the quality and maturity of its  investments,  purchasing  only  securities
  having  remaining  maturities of not more than 13 months and by  maintaining a
  weighted average portfolio maturity of not more than 90 days.
       Cash Reserve  invests  substantially  all of its assets in a  diversified
  portfolio of U.S. dollar denominated  high-quality  money market  instruments,
  consisting of:
  (1) Securities issued or guaranteed by the U.S.
      government and its agencies and instrumentalities. (For a description of
      such securities, see "U.S. Governments Short-Term," on this page.)
  (2) Commercial Paper.
  (3) Certificates of Deposit and Euro Dollar Certificates of Deposit.
  (4) Bankers' Acceptances.
  (5) Short-term notes, bonds, debentures, or other debt instruments.
  (6) Repurchase agreements.
      These  classes  of  securities  may be held in any  proportion,  and  such
  proportion may vary as market conditions  change.
      All portfolio  holdings are limited to those which at the time of purchase
  have a short-term rating of A-1 by S&P or P-1 by Moody's, or if they have no
  short-term rating are issued or guaranteed by an entity having a long-term
  rating of at least AA by S&P or Aa by Moody's.

  U.S. GOVERNMENTS SHORT-TERM
  U.S. GOVERNMENTS INTERMEDIATE-TERM
       These  funds seek to provide a  competitive  level of income and  limited
  price  volatility by investing in  securities of the United States  government
  and its agencies.
       The  two  funds  differ  in the  weighted  average  maturities  of  their
  portfolios  and  accordingly  in their  degree  of risk and  level of  income.
  Generally, the longer the weighted average maturity of a fund's portfolio, the
  higher the yield and the greater the price volatility.
       U.S.  Governments  Short-Term will maintain a weighted average  portfolio
  maturity of three years or less.  The fund is designed for  investors  who can
  accept  some  fluctuation  in  principal  in order  to earn a higher  level of
  current income than is generally  available from money market securities,  but
  who do not  want  as much  price  volatility  as is  inherent  in  longer-term
  securities.
       U.S.  Governments  Intermediate-Term  will  maintain a  weighted  average
  portfolio  maturity of three to 10 years.  The fund is designed for  investors
  seeking a higher  level of current  income than is  generally  available  from
  shorter-term  government  securities  and who are  willing to accept a greater
  degree of price fluctuation.


                                       11

<PAGE>

       The market value of the securities in which U.S.  Governments  Short-Term
  and U.S. Governments Intermediate-Term invest will fluctuate, and accordingly,
  the value of your  shares  will vary from day to day.  (See  "Fundamentals  of
  Fixed Income Investing," page 13.)
       Both  funds may invest in (1) direct  obligations  of the United  States,
  such as Treasury bills, notes and bonds, which are supported by the full faith
  and   credit  of  the   United   States,   and  (2)   obligations   (including
  mortgage-related   securities)   issued  or   guaranteed   by   agencies   and
  instrumentalities  of the United States  government that are established under
  an  act  of  Congress.   The   securities  of  some  of  these   agencies  and
  instrumentalities,  such as the Government National Mortgage Association,  are
  guaranteed  as to  principal  and  interest  by the U.S.  Treasury,  and other
  securities are supported by the right of the issuer,  such as the Federal Home
  Loan Banks, to borrow from the Treasury.  Other  obligations,  including those
  issued by the Federal National Mortgage  Association and the Federal Home Loan
  Mortgage Corporation, are supported only by the credit of the instrumentality.
       Mortgage-related  securities  in  which  the  funds  may  invest  include
  collateralized  mortgage obligations ("CMOs") issued by a United States agency
  or  instrumentality.  A CMO is a debt  security  that is  collateralized  by a
  portfolio  or pool of mortgages or  mortgage-backed  securities.  The issuer's
  obligation  to  make  interest  and  principal  payments  is  secured  by  the
  underlying pool or portfolio of mortgages or securities.
       The market value of mortgage-related  securities, even those in which the
  underlying pool of mortgage loans is guaranteed as to the payment of principal
  and interest by the United States  government,  is not insured.  When interest
  rates rise,  the market  value of those  securities  may  decrease in the same
  manner as other debt, but when interest rates decline,  their market value may
  not  increase  as much as other debt  instruments  because  of the  prepayment
  feature inherent in the underlying mortgages. If such securities are purchased
  at a  premium,  the fund  will  suffer a loss if the  obligation  is  prepaid.
  Prepayments will be reinvested at prevailing rates, which may be less than the
  rate paid by the prepaid obligation.
       For the purpose of determining the weighted average portfolio maturity of
  the funds,  management  shall  consider  the  maturity  of a  mortgage-related
  security  to be the  remaining  expected  average  life of the  security.  The
  average life of such  securities is likely to be  substantially  less than the
  original  maturity as a result of  prepayments  of principal on the underlying
  mortgages, especially in a declining interest rate environment. In determining
  the remaining  expected average life,  management makes assumptions  regarding
  prepayments on underlying  mortgages.  In a rising interest rate  environment,
  those  prepayments  generally  decrease,  and may  decrease  below the rate of
  prepayment  assumed by  management  when  purchasing  those  securities.  Such
  slowdown may cause the  remaining  maturity of those  securities  to lengthen,
  which will increase the relative  volatility of those  securities  and, hence,
  the  fund  holding  the  securities.   (See   "Fundamentals  of  Fixed  Income
  Investing," page 13.)

  LIMITED-TERM BOND
  INTERMEDIATE-TERM BOND
  LONG-TERM BOND
       These funds seek to provide investors with income through  investments in
  bonds and other debt instruments.
       The  three  funds  differ in the  weighted  average  maturities  of their
  portfolios  and  accordingly  in their  degree  of risk and  level of  income.
  Generally,  the longer the weighted average maturity, the higher the yield and
  the greater the price volatility.
       Limited-Term  Bond will invest  primarily in investment  grade  corporate
  securities and other debt  instruments and will maintain,  under normal market
  conditions,  a weighted  average  maturity of five years or less.  The fund is
  designed for  investors  seeking a  competitive  level of current  income with
  limited price volatility.
       Intermediate-Term Bond will invest primarily in investment grade
  corporate securities and other

                                       12

<PAGE>

  debt instruments and will maintain, under normal market conditions, a weighted
  average  maturity  of three to 10 years.  The fund is designed  for  investors
  seeking a higher  level of current  income than is  generally  available  from
  shorter-term corporate and government securities and who are willing to accept
  a greater degree of price fluctuation.
       Long-Term Bond will invest  primarily in investment grade corporate bonds
  and other debt instruments and will, under normal market conditions,  maintain
  a weighted  average  portfolio  maturity of 10 years or  greater.  The fund is
  designed for investors  whose primary goal is a level of current income higher
  than is  generally  provided by money  market or short- and  intermediate-term
  securities  and  who  can  accept  the  generally   greater  price  volatility
  associated with longer-term bonds.
       The value of the shares of all three of these funds will vary from day to
  day. (See "Fundamentals of Fixed Income Investing," on this page.)
       Under normal market  conditions,  each fund will maintain at least 65% of
  the  value of its total  assets  in  investment  grade  bonds  and other  debt
  instruments.  Under normal market conditions,  each of the funds may invest up
  to 35% of its assets,  and for temporary  defensive purposes up to 100% of its
  assets, in short-term money market instruments.
       Management will actively  manage the  portfolios,  adjusting the weighted
  average  portfolio  maturities as necessary in response to expected changes in
  interest rates.  During periods of rising interest rates, the weighted average
  maturity of a fund may be moved to the shorter  end of its  maturity  range in
  order to reduce  the  effect of bond  price  declines  on the fund's net asset
  value.  When interest rates are falling and bond prices  rising,  the weighted
  average portfolio  maturity may be moved toward the longer end of its maturity
  range.
       To  achieve  their  objectives,  the funds  will  invest  in  diversified
  portfolios of high- and medium-grade debt securities  payable in United States
  currency.  The funds will invest in  securities  which at the time of purchase
  are rated by a nationally  recognized  statistical rating  organization or, if
  not  rated,  are  of  equivalent  investment  quality  as  determined  by  the
  management,  as follows:  short-term  notes within the two highest  categories
  (for example, at least MIG-2 by Moody's or SP-2 by S&P); corporate,  sovereign
  government,  and  municipal  bonds  within the four  highest  categories  (for
  example,  at least Baa by  Moody's  or BBB by S&P);  securities  of the United
  States  government  and its  agencies  and  instrumentalities  (see  the  U.S.
  Governments  funds,  page 11); other types of securities rated at least P-2 by
  Moody's or A-2 by S&P. 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
  or changing circumstances.
       As noted, each fund may invest up to 35% of its assets, and for temporary
  defensive  purposes as determined by the manager,  up to 100% of its assets in
  short-term  money market  instruments.  Those  instruments  may  include:
  (1) Securities issued or guaranteed by the U.S. government and its agencies
      and instrumentalities;
  (2) Commercial Paper;
  (3) Certificates  of Deposit and Euro  Dollar  Certificates  of Deposit;
  (4) Bankers' Acceptances;
  (5) Short-term notes, bonds, debentures, or other debt instruments;
  (6) Repurchase agreements;
  and must meet the rating standards set out above. To the extent a fund assumes
  a defensive position, the weighted average maturity of its portfolio may not
  fall within the ranges stated above for the fund.

  FUNDAMENTALS OF
  FIXED INCOME INVESTING
       Over time,  the level of  interest  rates  available  in the  marketplace
  changes.  As prevailing  rates fall, the prices of bonds and other  securities
  that trade on a yield basis rise. On the other hand, when prevailing  interest
  rates rise, bond prices fall.

                        BOND PRICE VOLATILITY
       For a given  change  in  interest  rates,  longer
       maturity bonds experience a greater change in price,

       Generally,  the longer the  maturity of a debt  security,  the higher its
  yield and the  greater  its price  volatility.  Conversely,  the  shorter  the
  maturity, the lower the yield but the greater the price stability.
       These factors  operating in the marketplace have a similar impact on bond
  portfolios. A change in the level of interest rates causes the net asset value
  per share of any bond fund, except money market funds, to change. If sustained
  over time,  it would also have the impact of raising or lowering  the yield of
  the fund.
       In addition to the risk arising from  fluctuating  interest  rate levels,
  debt securities are subject to credit risk. When a security is purchased,  its
  anticipated  yield is dependent on the timely  payment by the borrower of each
  interest and principal installment. Credit analysis and resultant bond ratings
  take into account the relative likelihood that such timely payment will occur.
  As a result,  lower-rated  bonds  tend to sell at  higher  yield  levels  than
  top-rated bonds of similar maturity. In addition,  as economic,  political and
  business developments unfold,  lower-quality bonds, which possess lower levels
  of  protection  with  regard to timely  payment,  usually  exhibit  more price
  fluctuation than do higher-quality bonds of like maturity.
       The investment  practices of Twentieth  Century's  fixed income funds and
  the  fixed  income  portion  of the  balanced  fund take  into  account  these
  relationships.  The maturity and asset quality of each fund have  implications
  for the degree of price  volatility  and the yield level to be  expected  from
  each.

OTHER INVESTMENT PRACTICES

       For additional  information,  see "Investment  Restrictions Applicable to
  All Series of Shares" in the statement of additional information.

  PORTFOLIO TURNOVER
       The total portfolio turnover rates of the funds, except Cash Reserve, are
  shown in the Financial Highlights table on pages 5 to 8 of this prospectus.
       With respect to each series of shares,  investment  decisions to purchase
  and sell securities are based on the anticipated  contribution of the security
  in  question  to the  particular  fund's  objectives.  The  rate of  portfolio
  turnover  is  irrelevant  when  management  believes  a change  is in order to
  achieve those objectives and accordingly,  the annual portfolio  turnover rate
  cannot be anticipated.
       The portfolio turnover of each fund may be higher than other mutual funds
  with  similar   investment   objectives.   A  high   turnover   rate  involves
  correspondingly higher transaction costs that are borne directly by a fund. It
  may  also  affect  the  character  of  capital  gains,  if any,  realized  and
  distributed by a fund since  short-term  capital gains are taxable as ordinary
  income.

  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  repurchase  it on a
  specified date in the future at an  agreed-upon  price.  The repurchase  price
  reflects an  agreed-upon  interest  rate  during the time the fund's  money is
  invested in the security.
       Since the security  purchased  constitutes  security  for the  repurchase
  obligation,  a repurchase  agreement can be considered a loan  collaterized by
  the  security  purchased.  The fund's risk is the ability of the seller to pay
  the  agreed-upon  repurchase  price  on the  repurchase  date.  If the  seller
  defaults, the fund may incur costs in disposing of the collateral, which would
  reduce the amount  realized  thereon.  If the seller  seeks  relief  under the
  bankruptcy laws, the disposition of the collateral may be delayed or limited.
  To the extent the value of the security decreases, the fund could experience a
  loss.
       The funds will limit  repurchase  agreement  transactions  to  securities
  issued by the United States  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.
       Each of the funds may invest in repurchase agreements with respect to any
  security in which that fund is  authorized  to invest,  even if the  remaining
  maturity of the underlying  security  would make that security  ineligible for
  purchase  by such fund.  No fund will invest more than 15% (10% in the case of
  Cash  Reserve) of its assets in  repurchase  agreements  maturing in more than
  seven days.

  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.  Certain  derivative  securities are more accurately
  described as "index/structured"  securities.  Index/structured  securities are
  derivative  securities  whose value or  performance  is linked to other equity
  securities (such as Depositary Receipts, discussed under "Foreign Securities,"
  page 16),  currencies,  interest rates,  indexes or other financial indicators
  ("reference  indexes").  No fund may  invest in an  index/structured  security
  unless  the  reference  index or the  instrument  to which  it  relates  is an
  eligible  investment for the fund. For example, a bond whose interest rate was
  indexed to the return on two-year  treasury  securities would be a permissible
  investment (assuming it met the other


                                       15

<PAGE>

  requirements  for a fund),  while a bond whose return was indexed to the price
  of oil would not be a permissible investment.
       The return,  interest rate or, unlike most fixed income  securities,  the
  principal  amount payable at maturity of an  index/structured  security may be
  increased  or  decreased,  depending  upon  changes  in the  reference  index.
  Index/structured  securities  may be positively or  negatively  indexed.  That
  means that an  increase  in the  reference  index may  produce an  increase or
  decrease in the return, interest rate or value at maturity of the security.
       No  purchases  will  be  made  of   index/structured   securities  having
  "leverage"  characteristics.  This means that no  investments  will be made in
  securities  whose  change in return,  interest  rate or value at maturity is a
  multiple  of  the  change  in  the  reference  index.  In  no  event  will  an
  index/structured  security be  purchased  if its  addition  to a fixed  income
  fund's portfolio, or to the fixed income portion of Balanced Investors,  would
  cause the expected interest rate  characteristics of such fund to fall outside
  the  expected  interest  rate  characteristics  of  a  fund  having  the  same
  permissible  weighted average portfolio maturity range that does not invest in
  index/structured securities.
       Because their  performance is tied to a reference index, a fund investing
  in  index/structured  securities,  in addition to being  exposed to the credit
  risk of the issuer of the security,  will also bear the market risk of changes
  in the reference index.
       The  board  of  directors  has  approved  management's  policy  regarding
  investments in derivative securities.  That policy specifies factors that must
  be considered in connection  with the purchase of derivative  securities.  The
  policy  also  establishes  a  committee  that  must  review  certain  proposed
  purchases  before the  purchases can be made.  Management  will report on fund
  activity in derivative  securities to the board of directors as necessary.  In
  addition,  the board  will  review  management's  policy  for  investments  in
  derivative securities annually.

  PORTFOLIO LENDING
       In order to realize additional  income,  each fund may lend its portfolio
  securities  to  persons  not  affiliated  with  it and who  are  deemed  to be
  creditworthy.  Such  loans  must be secured  continuously  by cash  collateral
  maintained  on a current basis in an amount at least equal to the market value
  of the  securities  loaned,  or by irrevocable  letters of credit.  During the
  existence of the loan, the fund must continue to receive the equivalent of the
  interest  and  dividends  paid by the  issuer  on the  securities  loaned  and
  interest on the investment of the collateral.  The fund must have the right to
  call the loan and  obtain  the  securities  loaned  at any time on five  days'
  notice,  including,  if  applicable,  the  right to call  the  loan to  enable
  Twentieth Century to vote the securities.  Such loans may not exceed one-third
  of the fund's net assets taken at market.  Interest on loaned  securities  may
  not exceed  10% of the annual  gross  income of the fund  (without  offset for
  realized  capital  gains).  The  portfolio  lending  policy  described in this
  paragraph  is a  fundamental  policy  that  may be  changed  only by a vote of
  Twentieth Century's shareholders.
       Twentieth  Century  is  indemnified  against  loss on the loans by United
  States Trust Company of New York.

  FOREIGN SECURITIES
       Each of Twentieth Century's funds offered by this prospectus, except U.S.
  Governments  Short-Term and U.S. Governments  Intermediate-Term  may invest an
  unlimited amount of its assets in the securities of foreign issuers, primarily
  from developed markets, when these securities meet its standards of selection.
  The funds may make  such  investments  either  directly  in, or by  purchasing
  Depositary  Receipts  ("DRs")  for  foreign  securities.  DRs are listed on an
  exchange or quoted in the over-the-counter market in one country but represent
  the shares of issuers  domiciled in other  countries.  DRs may be sponsored or
  unsponsored.  Direct  investments in foreign  securities may be made either on
  foreign securities exchanges or in the over-the-counter markets.
       Subject to their individual investment objectives and policies, the funds
  may invest in common stocks, convertible securities, preferred stocks, bonds,


                                       16

<PAGE>

  notes and other debt  securities of foreign  issuers,  and debt  securities of
  foreign governments and their agencies. The funds will limit their purchase of
  debt securities to investment grade obligations.
       Investments in foreign  securities may present  certain risks,  including
  those resulting from fluctuations in currency exchange rates, future political
  and  economic   developments,   reduced  availability  of  public  information
  concerning  issuers,  and the fact  that  foreign  issuers  are not  generally
  subject to uniform  accounting,  auditing and financial reporting standards or
  to other regulatory practices and requirements  comparable to those applicable
  to domestic issuers.

  FORWARD CURRENCY
  EXCHANGE CONTRACTS
       Some of the foreign  securities  held by the funds may be  denominated in
  foreign currencies.  Other securities, such as DRs, may be denominated in U.S.
  dollars,  but have a value that is dependent on the  performance  of a foreign
  security,  as valued in the  currency of its home  country.  As a result,  the
  value of the funds'  portfolios  may be  affected  by changes in the  exchange
  rates between foreign  currencies and the dollar, as well as by changes in the
  market  values  of the  securities  themselves.  The  performance  of  foreign
  currencies  relative to the dollar may be a factor in the overall  performance
  of the funds.
       To  protect   against   adverse   movements  in  exchange  rates  between
  currencies,  the funds may,  for hedging  purposes  only,  enter into  forward
  currency exchange  contracts.  A forward currency exchange contract  obligates
  the  fund to  purchase  or sell a  specific  currency  at a  future  date at a
  specific price.
       A fund may elect to enter into a forward currency  exchange contract with
  respect to a specific  purchase or sale of a security,  or with respect to the
  fund's portfolio positions generally.
       By entering into a forward currency exchange contract with respect to the
  specific purchase or sale of a security  denominated in a foreign currency,  a
  fund can "lock in" an exchange rate between the trade and settlement dates for
  that purchase or sale. This practice is sometimes  referred to as "transaction
  hedging." Each fund may enter into transaction  hedging contracts with respect
  to all or a substantial portion of its foreign securities trades.
       When the manager believes that a particular currency may decline in value
 compared  to the  dollar,  a fund may  enter  into  forward  currency  exchange
 contracts to sell the value of some or all of the fund's  portfolio  securities
 either denominated in, or whose value is tied to, that currency.  This practice
 is sometimes  referred to as  "portfolio  hedging." A fund may not enter into a
 portfolio hedging  transaction where it would be obligated to deliver an amount
 of  foreign  currency  in  excess  of the  aggregate  value  of  its  portfolio
 securities  or other  assets  denominated  in, or whose  value is tied to, that
 currency.
       Each fund will make use of the  portfolio  hedging to the  extent  deemed
 appropriate by the manager.  However,  it is anticipated that a fund will enter
 into portfolio hedges much less frequently than transaction hedges.
       If a fund enters into a forward contract,  the fund, when required,  will
 instruct its custodian bank to segregate cash or liquid  high-grade  securities
 in a separate account in an amount sufficient to cover its obligation under the
 contract.  Those assets will be valued at market daily, and if the value of the
 segregated securities declines,  additional cash or securities will be added so
 that the  value of the  account  is not less  than  the  amount  of the  fund's
 commitment.  At any given  time,  no more than 10% of a fund's  assets  will be
 committed  to  a  segregated  account  in  connection  with  portfolio  hedging
 transactions.
       Predicting  the relative  future values of currencies is very  difficult,
 and there is no assurance  that any attempt to protect a fund  against  adverse
 currency  movements through the use of forward currency exchange contracts will
 be successful.  In addition,  the use of forward  currency  exchange  contracts
 tends to limit the potential  gains that might result from a positive change in
 the relationships between the foreign currency and the U.S. dollar.


                                       17

<PAGE>

  WHEN-ISSUED SECURITIES
       Each of the funds may  sometimes  purchase new issues of  securities on a
  when-issued  basis  without  limit when,  in the opinion of the manager,  such
  purchases  will further the  investment  objectives of the fund.  The price of
  when-issued  securities is established  at the time  commitment to purchase is
  made.  Delivery of and payment for these  securities  typically occur 15 to 45
  days after the  commitment  to  purchase.  Market  rates of  interest  on debt
  securities  at the  time  of  delivery  may be  higher  or  lower  than  those
  contracted for on the  when-issued  security.  Accordingly,  the value of such
  security may decline  prior to  delivery,  which could result in a loss to the
  fund.  A separate  account for each fund  consisting  of cash or  high-quality
  liquid  debt  securities  in an  amount  at  least  equal  to the  when-issued
  commitments  will be established and maintained with the custodian.  No income
  will accrue to the fund prior to delivery.

  RULE 144A SECURITIES
       Cash Reserve  will not invest more than 10% of its assets,  while each of
  the  other  funds  will not  invest  more than 15% of its  assets in  illiquid
  securities (securities that may not be sold within seven days at approximately
  the price used in determining  the net asset value of fund shares),  including
  restricted  securities.  Although  securities  which  may be  resold  only  to
  qualified  institutional buyers in accordance with the provisions of Rule 144A
  under the Securities Act of 1933 are considered "restricted  securities," each
  fund may purchase Rule 144A securities without regard to the percentage limits
  described  above  when  those  securities  present  an  attractive  investment
  opportunity and otherwise meet Twentieth Century's criteria of selection.
       With respect to securities eligible for resale under Rule 144A, the staff
  of the  Securities  and Exchange  Commission  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  Twentieth
  Century has delegated the day-to-day  function of determining the liquidity of
  Rule 144A securities to the manager.  The board retains the  responsibility to
  monitor the implementation of the guidelines and procedures it has adopted.
       Since the  secondary  market  for such  securities  is limited to certain
  institutional  investors,  the  liquidity  of such  securities  may be limited
  accordingly and a fund may from time to time hold a Rule 144A security that is
  illiquid.  In such an  event,  Twentieth  Century  will  consider  appropriate
  remedies to minimize the effect on the fund's liquidity.

  INTEREST RATE FUTURES CONTRACTS
  AND OPTIONS THEREON
       The corporate bond funds may buy and sell interest rate futures contracts
  relating to debt securities  ("debt  futures," i.e.,  futures relating to debt
  securities,  and "bond index  futures," i.e.,  futures  relating to indexes on
  types or groups of bonds) and write and buy put and call  options  relating to
  interest rate futures contracts.
       For  options  sold,  a fund  will  segregate  cash or  high-quality  debt
  securities  equal to the value of securities  underlying the option unless the
  option is otherwise covered.
       A fund will  deposit in a  segregated  account  with its  custodian  bank
  high-quality  debt  obligations  maturing in one year or less,  or cash, in an
  amount equal to the fluctuating  market value of long futures contracts it has
  purchased, less any margin deposited on its long position. It may hold cash or
  acquire such debt obligations for the purpose of making these deposits.
       A fund will purchase or sell futures  contracts and options  thereon only
  for the  purpose  of  hedging  against  changes  in the  market  value  of its
  portfolio  securities or changes in the market value of securities that it may
  wish to include in its

                                       18

<PAGE>

  portfolio.  A fund will enter into future and option  transactions only to the
  extent that the sum of the amount of margin  deposits on its existing  futures
  positions  and  premiums  paid for  related  options  do not  exceed 5% of its
  assets.
       Since futures  contracts and options  thereon can replicate  movements in
  the cash markets for the securities in which a fund invests  without the large
  cash investments required for dealing in such markets, they may subject a fund
  to greater  and more  volatile  risks than might  otherwise  be the case.  The
  principal risks related to the use of such  instruments are (1) the offsetting
  correlation between movements in the market price of the portfolio investments
  (held or intended)  being  hedged and in the price of the futures  contract or
  option may be imperfect;  (2) possible lack of a liquid  secondary  market for
  closing out futures or option positions; (3) the need for additional portfolio
  management skills and techniques;  and (4) losses due to unanticipated  market
  price movements.  For a hedge to be completely effective,  the price change of
  the hedging  instrument  should equal the price change of the securities being
  hedged.  Such  equal  price  changes  are  not  always  possible  because  the
  investment  underlying the hedging  instrument may not be the same  investment
  that is being hedged.
        Management will attempt to create a closely correlated hedge but hedging
  activity  may  not  be  completely  successful  in  eliminating  market  value
  fluctuation.  The  ordinary  spreads  between  prices in the cash and  futures
  markets,  due to the differences in the natures of those markets,  are subject
  to distortion.  Due to the  possibility of distortion,  a correct  forecast of
  general  interest  rate  trends by the  management  may still not  result in a
  successful transaction.  Management may be incorrect in its expectations as to
  the extent of various  interest  rate  movements or the time span within which
  the movements  take place.  (See the statement of additional  information  for
  further information about these instruments and their risks.)

  SHORT SALES
       Twentieth  Century's  funds  described in this  prospectus  may engage in
  short sales if, at the time of the short sale,  the fund owns or has the right
  to acquire an equal amount of the security  being sold short at no  additional
  cost. These  transactions  allow a fund to hedge against price fluctuations by
  locking in a sale price for securities it does not wish to sell immediately.
       A fund may make a short sale 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 and for purposes of  satisfying  certain
  tests applicable to regulated  investment companies under the Internal Revenue
  Code.

  PERFORMANCE ADVERTISING
       From time to time, Twentieth Century may advertise performance data. Fund
  performance may be shown by presenting one or more  performance  measurements,
  including  cumulative  total return or average  annual total return and,  with
  respect to the fixed income funds and the balanced  fund,  yield and effective
  yield.
       Cumulative  total return data is computed by considering  all elements of
  return,  including  reinvestment of dividends and capital gains distributions,
  over a stated  period of time.  Average  annual total return is  determined by
  computing the annual  compound  return over a stated period of time that would
  have  produced a fund's  cumulative  total  return over the same period if the
  fund's performance had remained constant throughout.
       A  quotation  of yield  reflects  a fund's  income  over a stated  period
  expressed  as a  percentage  of the fund's  share  price.  In the case of Cash
  Reserve,  yield  is  calculated  by  measuring  the  income  generated  by  an
  investment in the fund over a seven-day  period (net of fund  expenses).  This
  income is then  "annualized."  That is, the amount of income  generated by the
  investment  over the  seven-day  period is assumed to be  generated  over each
  similar  period each week  throughout a full year and is shown as a percentage
  of the  investment.  The  "effective  yield" is calculated in a similar manner
  but, when annualized,

                                      19

<PAGE>

  the income earned by the investment is assumed to be reinvested. The effective
  yield will be slightly higher than the yield because of the compounding effect
  of the assumed reinvestment.
       With respect to Twentieth Century's other fixed income funds and Balanced
  Investors,  yield is calculated by adding over a 30-day (or one-month)  period
  all interest and dividend  income (net of fund  expenses)  calculated  on each
  day's market  values,  dividing this sum by the average  number of fund shares
  outstanding  during the period,  and  expressing the result as a percentage of
  the fund's  share price on the last day of the 30-day (or  one-month)  period.
  The percentage is then  annualized.  Capital gains and losses are not included
  in the calculation.
       Yields  are   calculated   according  to  accounting   methods  that  are
  standardized  in  accordance  with SEC rules  for all  stock  and bond  funds.
  Because  yield  accounting  methods  differ  from the  methods  used for other
  accounting  purposes,  the fund's  yield may not equal the income paid on your
  shares or the income reported in the fund's financial statements.
       The funds may also include in advertisements  data comparing  performance
  with the  performance of non-related  investment  media,  published  editorial
  comments and performance rankings compiled by independent  organizations (such
  as  Lipper   Analytical   Services  or  Donoghue's   Money  Fund  Report)  and
  publications  that  monitor  the  performance  of  mutual  funds.  Performance
  information may be quoted numerically or may be presented in a table, graph or
  other  illustration.   In  addition,  fund  performance  may  be  compared  to
  well-known  indices of market  performance,  including  the  Standard & Poor's
  (S&P) 500  Index,  the Dow Jones  Industrial  Average,  Donoghue's  Money Fund
  Average and the Bank Rate Monitor National Index of 2 1/2-year CD rates.  Fund
  performance  may also be  compared  to other  funds in the  Twentieth  Century
  family.  It may also be combined or blended with other funds in the  Twentieth
  Century  family,  and that combined or blended  performance may be compared to
  the same indices to which individual funds may be compared.
       All  performance  information  advertised  by the 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.

                      HOW TO INVEST WITH TWENTIETH CENTURY
- --------------------------------------------------------------------------------

  TWENTIETH CENTURY FAMILY OF FUNDS
       In addition to the 16 funds offered by Twentieth Century Investors, Inc.,
  the Twentieth Century family of funds also includes funds offered by Twentieth
  Century World Investors,  Inc.,  Twentieth Century Premium Reserves,  Inc. and
  Twentieth Century Capital Portfolios,  Inc. Please call the Investors Line for
  a prospectus and additional information about the other funds in the Twentieth
  Century family of funds.

  INVESTING IN TWENTIETH CENTURY
       One or more of the funds  offered by this  prospectus  is available as an
  investment option in your  employer-sponsored  retirement or savings plan. All
  orders  to  purchase   shares  must  be  made  through  your   employer.   The
  administrator  of your plan or your employee  benefits  office can provide you
  with  information  on how to  participate  in your  plan  and how to  select a
  Twentieth Century fund as an investment option.
       If you have questions about a fund, see  "Information  About  Investment
  Policies of the Funds," page 9, or call Twentieth  Century's Investors Line at
  1-800-345-3533.
       Orders to purchase  shares are  effective on the day  Twentieth  Century
  receives payment. (See "When Share Price is Determined," page 23.)
       Twentieth Century may discontinue  offering shares generally in the funds
  or in any particular state without notice to shareholders.

  HOW TO CONVERT YOUR
  INVESTMENT FROM ONE TWENTIETH
  CENTURY FUND TO ANOTHER
       Your plan may permit you to exchange ("convert") your investment from the
  shares of a fund to shares of another  fund.  See your plan  administrator  or
  employee  benefits  office  for  details  on the rules in your plan  governing
  conversions,  or call Twentieth  Century's  Investors Line at  1-800-345-3533.
  Conversions  will be accepted by  Twentieth  Century only as permitted by your
  plan.
       Conversions  are made at the respective  net asset values,  next computed
  after receipt of the conversion  instruction by Twentieth  Century.  If in any
  90-day period,  the total of the conversions and redemptions from any one plan
  participant's  accounts in the equity funds or the  balanced  fund exceeds the
  lesser of  $250,000  or 1% of a fund's  assets,  further  conversions  will be
  subject to special  requirements to comply with Twentieth  Century's policy on
  large equity fund  redemptions.  (See "Special  Requirements  for Large Equity
  Fund Redemptions," on this page.)

  HOW TO REDEEM SHARES
       Subject to any restrictions imposed by your employer's plan, you can sell
  ("redeem")  your shares  through the plan at their net asset value.  Your plan
  administrator,  trustee,  or other  designated  person must provide  Twentieth
  Century with redemption  instructions.  The shares will be redeemed at the net
  asset value next  computed  after receipt of the  instructions  in good order.
  (See,  "When Share Price Is  Determined,"  page 23.) If you have any questions
  about how to redeem, contact your plan administrator or your employee benefits
  office.

  SPECIAL REQUIREMENTS FOR
  LARGE EQUITY FUND REDEMPTIONS
       Twentieth  Century  has  elected to be  governed  by Rule 18f-1 under the
  Investment  Company Act,  which  obligates each fund to redeem shares in cash,
  with respect to any one  participant  account during any 90-day period,  up to
  the lesser of $250,000 or 1% of the assets of the fund.  Although  redemptions
  in excess of this  limitation  will also  normally be paid in cash,  Twentieth
  Century  reserves the right to honor these  redemptions  by making  payment in
  whole or in part in readily

                                      21

<PAGE>

  marketable  securities  (a  "redemption-in-kind").   If  payment  is  made  in
  securities, the securities will be selected by the fund, will be valued in the
  same  manner as they are in  computing  the fund's net asset value and will be
  provided to the  redeeming  plan  participant  in lieu of cash  without  prior
  notice.
       If you  expect to make a large  redemption  and  would  like to avoid any
  possibility of being paid in securities,  you may do so by providing Twentieth
  Century 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.  Receipt of your instruction 15 days prior to the transaction
  provides the fund with  sufficient time to raise the cash in an orderly manner
  to pay the  redemption  and thereby  minimizes the effect of the redemption on
  the fund and its remaining shareholders.
       Despite  its right to redeem fund  shares  through a  redemption-in-kind,
  Twentieth Century does not expect to exercise this option unless a fund has an
  unusually  low  level  of cash  to meet  redemptions  and/or  is  experiencing
  unusually  strong  demands for its cash.  Such a demand  might be caused,  for
  example,  by extreme market conditions that result in an abnormally high level
  of redemption requests concentrated in a short period of time. Absent these or
  similar  circumstances,  Twentieth  Century  expects  redemptions in excess of
  $250,000  to be paid in cash in any fund with  assets of more than $50 million
  if total  redemptions  from any one account in any 90-day period do not exceed
  one-half of 1% of the total assets of the fund.
       The special  policies with respect to large  redemptions  described above
  apply only to the equity funds and the  balanced  fund.  Redemptions  from the
  fixed income funds will be paid in cash regardless of the redemption amount.

                     ADDITIONAL INFORMATION YOU SHOULD KNOW
- --------------------------------------------------------------------------------

  SHARE PRICE

  WHEN SHARE PRICE IS DETERMINED
       The price of your shares is their net asset value next  determined  after
  receipt of your instruction to purchase, convert or redeem. Net asset value is
  determined by calculating the total value of a fund's assets,  deducting total
  liabilities and dividing the result by the number of shares  outstanding.  Net
  asset  value is  determined  on each day that the New York Stock  Exchange  is
  open.
       Investments  and  requests to redeem  shares will receive the share price
  next determined after receipt by Twentieth  Century or its authorized agent of
  the investment or redemption request. For example, investments and requests to
  redeem shares received by Twentieth Century or its authorized agent before the
  close of business on the New York Stock Exchange, usually 3 p.m. Central time,
  are  effective on, and will receive the price  determined,  that day as of the
  close of the Exchange.  Redemption  requests received thereafter are effective
  on, and receive the price  determined  as of the close of the Exchange on, the
  next day the Exchange is open.


  HOW SHARE PRICE IS DETERMINED
       The valuation of assets for determining net asset value may be summarized
  as follows:
       The portfolio  securities of each fund, except as otherwise noted, listed
  or traded on a domestic  securities exchange are valued at the last sale price
  on that exchange. If no sale is reported, the mean of the latest bid and asked
  price is used.  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 good faith 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.
       Pursuant to a  determination  by Twentieth  Century's  board of directors
  that such value  represents fair value,  debt securities with maturities of 60
  days or less are  valued  at  amortized  cost.  When a  security  is valued at
  amortized  cost, it is valued at its cost when  purchased,  and  thereafter by
  assuming a constant  amortization  to  maturity  of any  discount  or premium,
  regardless of the impact of fluctuating  interest rates on the market value of
  the instrument.
       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,
  usually 3 p.m. Central time, if that is earlier.  That value is then converted
  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  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 a 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 a
  fund's  portfolio  may be  affected on days when shares of the fund may not be
  purchased or redeemed.

  WHERE TO FIND INFORMATION
  ABOUT SHARE PRICE
       The net asset  values of  Twentieth  Century's  funds  are  published  in
  leading  newspapers  daily.  The yield of Cash Reserve is published  weekly in
  leading  financial  publications and daily in many local  newspapers.  The net
  asset values, as well as yield information on all of Twentieth Century's fixed
  income funds, may be obtained by calling  Twentieth  Century.  (See "Telephone
  Services," page 22.)

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

  EQUITY FUNDS
       Distributions from investment income and from net profits realized on the
  sale of securities,  if any, will be declared  annually on or before  December
  31.
       THE  OBJECTIVE  OF  THESE  FUNDS  IS  CAPITAL  APPRECIATION  AND  NOT THE
  PRODUCTION OF DISTRIBUTIONS. YOU MAY MEASURE THE SUCCESS OF YOUR INVESTMENT BY
  THE VALUE OF YOUR  INVESTMENT  AT ANY GIVEN TIME AND NOT BY THE  DISTRIBUTIONS
  YOU RECEIVE.

  BALANCED FUND
       Distributions  from  investment  income will be paid  quarterly in March,
  June,  September and December.  Distributions from net profits realized on the
  sale of securities, if any, will be paid annually on or before December 31.

  FIXED INCOME FUNDS
       At the close of each day, including Saturdays,  Sundays and holidays, net
  income of the fixed income funds is determined and declared as a distribution.
  The distribution will be paid monthly on the last Friday of each month.
       You will begin to  participate  in the  distributions  the day AFTER your
  purchase is effective. (See "When Share Price is Determined," page 23.) If you
  redeem shares,  you will receive the distribution  declared for the day of the
  redemption.
       Any net realized  capital gains of the fixed income funds other than Cash
  Reserve  will be  distributed  at least  annually  on or before  December  31.
  Realized  gains on securities  in the Cash Reserve  portfolio may be paid with
  the daily dividend. Otherwise, they will be distributed annually after
  October 31 and before December 31.

  TAXES
       Twentieth  Century  has  elected to be taxed  under  Subchapter  M of the
  Internal Revenue Code, which means that because Twentieth Century  distributes
  all of its income, it pays no income taxes.
       If you  choose  to use one or more of  Twentieth  Century's  funds  as an
  investment  option in your  employer-sponsored  retirement  or  savings  plan,
  income and capital gains distributions paid by the funds will generally not be
  subject to current  taxation,  but will  accumulate  in your account under the
  plan on a tax-deferred basis.
       Employer-sponsored  retirement  and savings plans are governed by complex
  tax rules. If you elect to participate in your employer's  plan,  consult your
  plan  administrator,  your plan's summary plan description,  or a professional
  tax adviser  regarding  the tax  consequences  of  participation  in the plan,
  contributions to, and withdrawals or distributions from the plan.

  MANAGEMENT
       Under  the laws of the  State of  Maryland,  the  board of  directors  is
  responsible for managing the business and affairs of Twentieth Century. Acting
  pursuant to an  investment  advisory  agreement  entered  into with  Twentieth
  Century, Investors

  Research Corporation  ("Investors  Research") serves as the investment manager
  of Twentieth  Century.  Its principal  place of business is Twentieth  Century
  Tower, 4500 Main Street,  Kansas City, Missouri 64111.  Investors Research has
  been providing  investment advisory services to Twentieth Century since it was
  founded in 1958.
       Investors  Research  supervises and manages the investment  portfolios of
  Twentieth  Century  and  directs  the  purchase  and  sale  of its  investment
  securities. Investors Research utilizes teams of portfolio managers, assistant
  portfolio  managers and analysts  acting  together to manage the assets of the
  funds.  The teams meet regularly to review  portfolio  holdings and to discuss
  purchase and sale activity. The teams adjust holdings in the funds' portfolios
  as they deem  appropriate  in  pursuit of the  funds'  investment  objectives.
  Individual  portfolio  manager  members of the team may also adjust  portfolio
  holdings of the funds as necessary between team meetings.
       The portfolio  manager  members of the teams managing the funds described
  in this  prospectus  and their work  experience for the last five years are as

       Robert V. Gahagan,  Vice President and Portfolio Manager,  has worked for
  Twentieth  Century since May 1983.  He became a Portfolio  Manager in December
  1991. Prior to that he served as Assistant  Portfolio Manager.  He is a member
  of the team that manages Cash Reserve,  U.S.  Governments  Short-Term and U.S.
  Governments Intermediate-Term.
       The  activities  of Investors  Research are subject only to directions of
  Twentieth  Century's  board  of  directors.  Investors  Research  pays all the
  expenses of Twentieth  Century except  brokerage,  taxes,  interest,  fees and
  expenses of the non-interested  person directors  (including counsel fees) and
  extraordinary expenses.
       For the  services  provided  to  Twentieth  Century,  Investors  Research
  receives an annual fee at the following  rates:

     o 1% of the average net assets of Select, Heritage, Growth, Ultra, Vista
       and Balanced;
     o .80 of 1% of Long-Term Bond;
     o .75 of 1% of the average net assets of U.S. Governments Intermediate-Term
       and Intermediate-Term Bond; and
     o .70 of 1% of the average net assets of Limited-Term Bond, Cash Reserve
       and U.S. Governments Short-Term.

       On the first  business  day of each  month,  each series of shares pays a
  management  fee to the manager for the previous  month at the rate  specified.
  The fee for the previous month is calculated by multiplying the applicable fee
  for such series by the  aggregate  average  daily closing value of the series'
  net assets during the previous month, and further  multiplying that product 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 fees paid by the funds to Investors Research may be higher
  than that paid by many investment companies.  However, most if not all of such
  companies also pay in addition certain of their own expenses,  while virtually
  all of Twentieth  Century's  expenses  except as  specified  above are paid by
  Investors Research.
       Twentieth Century Services, Inc., 4500 Main Street, Kansas City, Missouri
  64111, acts as transfer agent and dividend paying agent for Twentieth Century.
  It provides  facilities,  equipment and personnel to Twentieth Century, and is
  paid for such services by Investors Research.  Certain recordkeeping  services
  that would otherwise be performed by Twentieth Century  Services,  Inc. may be
  performed by an insurance  company or other entity providing  similar services
  for various  retirement  plans using shares of Twentieth  Century as a funding
  medium  or by  broker  dealers  for  their  customers  investing  in shares of
  Twentieth  Century.  Investors  Research may elect to enter into a contract to
  pay them for such services.
       From time to time,  special  services may be offered to shareholders  who
  maintain  higher share  balances in the funds.  These services may include the
  waiver  of  minimum  investment   requirements,   expedited   confirmation  of
  shareholder transactions,  newsletters and a team of personal representatives.
  Any expenses  associated with these special services will be paid by Investors
  Research.
       Investors  Research and Twentieth Century Services,  Inc. are both wholly
  owned by Twentieth Century  Companies,  Inc. James E. Stowers Jr., chairman of
  the board of Twentieth Century Investors, controls Twentieth Century Companies
  by virtue of his ownership of a majority of its common stock.

  FURTHER INFORMATION
  ABOUT TWENTIETH CENTURY
       Twentieth Century Investors, Inc. was organized as a Maryland corporation
  on July 2, 1990. The  corporation  commenced  operations on February 28, 1991,
  the  date it  merged  with  Twentieth  Century  Investors,  Inc.,  a  Delaware
  corporation  which had been in business  since October  1958.  Pursuant to the
  terms of the  Agreement  and Plan of Merger dated July 27, 1990,  the Maryland
  corporation was the surviving

  entity and  continued the business of the Delaware  corporation  with the same
  officers  and  directors,  the  same  shareholders  and  the  same  investment
  objectives, policies and restrictions.
       Twentieth  Century  is  a  diversified,  open-end  management  investment
  company whose shares are presently held by more than 1.5 million shareholders.
  Its business and affairs are managed by its  officers  under the  direction of
  its board of directors.
       The principal  office of Twentieth  Century is Twentieth  Century  Tower,
  4500 Main Street,  P.O.  Box 419200,  Kansas City,  Missouri  64141-6200.  All
  inquiries may be made by mail to that address,  or by phone to 1-800-345-3533.
  (For local Kansas City area or international callers: 816-531-5575.)
       Twentieth  Century issues 16 series of $.01 par value shares.  The assets
  belonging to each series of shares are held  separately by the custodian,  and
  in effect each series is a separate fund.
       Each  share,  irrespective  of series,  is  entitled to one vote for each
  dollar of net asset value  applicable to such share on all  questions,  except
  those  matters  which  must be voted on  separately  by the  series  of shares
  affected.  Matters  affecting  only one  series  are  voted  upon only by that
  series.
       Shares have non-cumulative voting rights, which means that the holders of
  more than 50% of the shares voting for the election of directors can elect all
  of the directors if they choose to do so, and in such event the holders of the
  remaining  less-than-50% of the shares will not be able to elect any person or
  persons to the board of directors.
       Unless  required by the Investment  Company Act, it will not be necessary
  for Twentieth  Century to hold annual meetings of  shareholders.  As a result,
  shareholders  may not vote  each  year on the  election  of  directors  or the
  appointment of auditors.  However, pursuant to Twentieth Century's bylaws, the
  holders of shares  representing  at least 10% of the votes entitled to be cast
  may  request  Twentieth  Century to hold a special  meeting  of  shareholders.
  Twentieth Century will assist in the communication with other shareholders.
       TWENTIETH  CENTURY  RESERVES  THE  RIGHT TO CHANGE  ANY OF ITS  POLICIES,
  PRACTICES AND PROCEDURES DESCRIBED IN THIS PROSPECTUS, INCLUDING THE STATEMENT
  OF  ADDITIONAL  INFORMATION,  WITHOUT  SHAREHOLDER  APPROVAL  EXCEPT  IN THOSE
  INSTANCES WHERE SHAREHOLDER APPROVAL IS EXPRESSLY REQUIRED.
