Dear Shareholder:
We recently sent you proxy materials concerning
important proposals affecting your fund(s), which was considered a Meeting of Shareholders of the funds on January 16, 2026 at 2:00 p.m.,
Central Time. The Meeting has been adjourned to allow shareholders more time to vote. The Meeting will reconvene on February 26, 2026.
This letter was sent because you held shares in the fund(s) on the record date and we have not received
your vote.
YOUR FUND’S BOARD OF TRUSTEES RECOMMENDS THAT YOU VOTE "FOR"
THE PROPOSALS
YOUR VOTE IS VERY IMPORTANT
VOTING NOW HELPS MINIMIZE PROXY COSTS, AVOIDS UNNECESSARY COMMUNICATIONS
AND ELIMINATES PHONE CALLS TO SHAREHOLDERS
Your vote is very
important. We encourage you as a shareholder to participate in your fund’s governance by returning your vote as soon as possible.
If enough shareholders fail to cast their votes, a fund may not be able to hold its Meeting or the vote on the proposals and will be required
to incur additional solicitation costs in order to obtain sufficient shareholder participation. Because
your vote is critical, our outreach to you will continue until there is sufficient voting.
