Dear [Shareholder],
It was a pleasure speaking with you last week regarding your American Century
investment. I enjoyed our discussion very much, and I appreciate you taking the
time to talk with me. I hope the information I shared with you was helpful.
As we discussed, I am following up on our conversation with a copy of the
current proxy statements. As the majority shareholder in the Advisor Class of
our Tax-Free Bond fund, your vote is critical in our efforts to achieve quorum
in our ongoing proxy solicitation process. We would appreciate your serious
consideration very much.
While I know you currently have reservations about the significance of your
vote, it's important for you to know that two different independent bodies
recommend that shareholders vote in favor of the resolutions listed in the
proxy.
1. INSTITUTIONAL SHAREHOLDER SERVICES (ISS) - ISS is a company that
provides in-depth, objective proxy research and provides informed
voting recommendations to shareholders. Their mission is to help
shareholders manage risk and drive value. They have publicly
recommended that shareholders vote in favor of these proposals.
2. THE BOARD OF TRUSTEES FOR TAX-FREE BOND - The Board, which includes
all of the independent trustees, also unanimously recommends that
shareholders vote for the proposals. Keep in mind that these
independent members of the Board are not employees of American Century
Investments, and it's their job to oversee the funds on behalf of the
shareholders. They are the shareholders' advocate and have determined
that these proposals are in the best interest of shareholders.
The easiest and quickest way to vote is on-line or by phone. To vote on the
internet, go to www.proxyweb.com. You will need your proxy card control
number(s) from the information mailed to you to utilize the web site. If you
don't have access to that or prefer to call, phone toll-free at 877-256-6083 and
a proxy service representative will assist you.
I am happy to answer any additional questions you may have. Please don't
hesitate to contact me at your convenience.
Thank you again for your time and consideration.
Sincerely,
David Larrabee, Senior Vice President
