Oakmark Needs Your Vote

March 17, 2016

The Oakmark Funds mailed a Proxy Statement to our shareholders to vote on several important proposals at a shareholder meeting scheduled for May 20, 2016. We ask that you please review the Proxy Statement and proxy card provided to you via mail or e-delivery in early March. Your vote is important no matter how many shares you own and we ask that you please actively participate in the proxy process.

The purpose of the meeting is to seek your approval on a number of important proposals recommended by the Board of Trustees that affect each of the Funds. These proposals include investment and governance-related initiatives that are intended to improve the operations of the Funds. We are taking this opportunity to modernize certain older, less flexible provisions of the Funds’ documents as part of the meeting so that they are more consistent with existing industry standards.

After you have reviewed the materials, please submit your vote promptly by one of the following methods:

· Online. Visit www.proxy-direct.com and follow the instructions. You will need your proxy card to vote.

· By phone. Call 1-800-337-3503 and follow the recorded instructions. You will need your proxy card to vote.

· By mail. You may vote by filling out the paper proxy card or voting instruction form.

· In person. You may attend the shareholder meeting and vote at the meeting.

If you have any questions about any proposal or need assistance voting your shares, please contact our proxy solicitor, Computershare Fund Services, at (866) 612-1831.
