C CLASS SHARES PROXY TALKING POINTS


Summary

American Century is asking shareholders to approve an increase in the 12b-1
distribution fee on its variable-priced fixed income C Class shares to 0.75%
from 0.50% for a total 12b-1 fee of 1.00% (i.e., distribution and service)
effective January 1, 2004. The 12b-1 fee is used as a trailing commission to
compensate financial advisors for the ongoing oversight and advice that they
provide to their clients. Affected funds include:

Why is American Century increasing the 12b-1 fee?

The overwhelming majority of mutual fund companies have structured their 12b-1
fees to enable them to pay such fees to financial professionals at an annual
rate of 1.00% of the average daily net asset value of a fund's C Class shares.
American Century's C Class, however, enables a payment equivalent to an annual
rate of only 0.75%, rather than 1.00%. In an increasingly competitive
environment for the sale of fund shares, the 12b-1 fee must be increased so that
the American Century funds can meet the increasing costs of distribution and
shareholder service and provide competitive compensation to financial
professionals.

Are any changes being proposed for American Century's
C class share equity funds?

No. C Class shares of American Century's equity funds are competitively priced
at the industry standard of 1.00% for traditional C Class shares, so changes are
not required. Only C Class shares of American Century variable-priced fixed
income funds will be changed if approved by shareholders.

How does an increase in the 12b-1 fee benefit investors?

The proposed increase will contribute to the long-term viability of each fund's
C Class shares. We believe that the lower fees paid to financial professionals
in connection with the sale of the funds' C Class shares will hamper growth of
the C Class considerably. In this environment, we have little confidence that
the funds' C Classes will grow sufficiently to cover their cost of operation.
Without the proposed 12b-1 fee increase, we believe that the funds' C Classes
may ultimately require liquidation. We believe that an investment vehicle with
long-term viability is a benefit to all long-term investors.

American Century also firmly believes that its C Class share investors place
value in the sound investment advice provided by their financial professionals.
The proposed 12b-1 fee increase will enable the funds to pay for this advice at
the industry-standard rate, which ultimately benefits the shareholder. Finally,
the proposed fee increase will stimulate additional sales of C Class shares of
the funds, thus increasing fund assets. Additional assets will ultimately
benefit fund shareholders, as portfolio managers have greater access to
investment opportunities and ability to trade securities more efficiently, and
shareholders may be able to benefit from breakpoints in management fees when
fund assets increase.

Why are the Trustees recommending a vote "FOR" the Proposal?

The Trustees reviewed this Proposal with investor interests in mind. They
believe that the proposed 12b-1 fee increase will serve investors well in the
long term by providing the benefits outlined above. In addition to these
benefits, the Trustees also considered that the entire amount of the increase
would be used to finance payments to financial professionals and therefore would
not be retained by American Century Investment Management, Inc. or its
affiliates.
