To date, we have not received your vote. Please take a few minutes to review the information provided in this letter and vote your shares. We cannot emphasize enough the importance of your vote, regardless of how many shares you own. Voting promptly also is important as the rescheduled meeting date is June 22.

The Agreement and Declarations of Trust for each Trust governs the basic operations of the Trusts. Shareholder approval is required for certain changes. The changes described in the proxy statement you received in April are intended to modernize the Declarations of Trust to accommodate changes in law or practice since the Declarations of Trust were last approved by shareholders, as well as to make the Declarations of Trust uniform across the Trusts. We anticipate that the overall effect of these changes will reduce costs and expenses in the administration of the Funds and provide more flexibility for the operations of the Funds, within limits of applicable law.
