heading "American Century Investments" on page 22 of the Investor Class
Prospectus and as the last paragraph under the heading "How to Purchase and Sell
American Century Funds" on page 21 of the Advisor Class Prospectus.
To reduce expenses and demonstrate respect for our environment, we have
initiated a project through which we will eliminate duplicate copies of most
financial reports and prospectuses to most households and deliver account
statements to most households in a single envelope, even if they have more than
one account. If additional copies of financial reports and prospectuses or
separate mailing of account statements is desired, please call us.
The following disclosure is added on page 28 of the Investor Class Prospectus
and page 22 of the Advisor Class Prospectus, following the last paragraph under
the heading "When Share Price is Determined."
We have contractual relationships with certain financial intermediaries in
which such intermediaries represent that they have systems to track the time at
which investment orders are received and to segregate orders received at
different times. Based on these representations, the fund has authorized such
intermediaries and their designees to accept purchase and redemption orders on
the fund's behalf up to the applicable cut-off time. The fund will be deemed to
have received such orders upon acceptance by the duly authorized intermediary,
and such orders will be priced at the fund's net asset value next determined
after acceptance on the fund's behalf by such intermediary.
The following disclosure is added on page 32 of the Investor Class Prospectus
