AMERICAN CENTURY TARGET MATURITIES TRUST
STATEMENT OF ADDITIONAL INFORMATION SUPPLEMENT
Supplement dated December 28, 1999 * Statement of Additional Information dated
February 1, 1999
The following is inserted immediately after the chart for Fundamental Investment
Policies on page 6.
For purposes of the investment restrictions relating to lending and borrowing,
the funds have received an exemptive order from the SEC regarding interfund
lending. Under the terms of the exemptive order, the funds may borrow money from
or lend money to other funds, advised by ACIM, that permit such transactions.
All such transactions will be subject to the limits set above for borrowing
and lending. The funds will borrow money through the program only when the costs
are equal to or lower than the cost of short-term bank loans. Interfund loans
and borrowings normally extend only overnight, but can have a maximum duration
of seven days. The funds will lend through the program only when the returns are
higher than those available from other short-term instruments (such as
repurchase agreements). The funds may have to borrow from a bank at a higher
interest rate if an interfund loan is called or not renewed. Any delay in
repayment to a lending fund could result in a lost investment opportunity or
additional borrowing costs.
