*The sub-section entitled "Board Structure" is deleted in its entirety and hereby replaced with the following:*

 

**Board Structure.** The Trust's Board includes three independent Trustees. Mr. Nusblatt serves as Chairman of the Board. The Trustees have determined that the Trust's current leadership structure is appropriate, as it allows Trust management to communicate with each independent Trustee as and when needed and permits each independent Trustee to be involved in each committee of the Board (each a "Committee") as well as each Board function. With respect to risk oversight, the Board holds quarterly meetings each year to consider and address matters involving the Trust and the Funds. During these meetings, the Board receives reports from the Funds' administrator, transfer agent and distributor, and Trust management, including the Trust's President, Mr. Byrd, and the Trust's CCO, Mr. Wowak, on regular quarterly items and, where appropriate and as needed, on specific issues. As part of its oversight function, the Board also may hold special meetings or communicate directly with the Trust's officers to address matters arising between regular meetings. The Board has established a committee structure that includes an Audit Committee (discussed in more detail below). The Audit Committee is comprised entirely of independent Trustees.
