SUMMARY OF THE EXPERIENCE AND QUALIFICATIONS OF TRUSTEES

Described below for each Trustee are specific experiences, qualifications, attributes, or skills that support a conclusion that he should serve as a Trustee of the Trust as of the date of this SAI and in light of the Trust’s business and structure. The role of an effective Trustee inherently requires certain personal qualities, such as integrity, as well as the ability to comprehend, discuss and critically analyze materials and issues that are presented so that the Trustee may exercise judgment and reach conclusions in fulfilling his duties and fiduciary obligations. It is believed that the specific background of each Trustee evidences those abilities and is appropriate to his serving on the Trust’s Board of Trustees. Further information about each Trustee is set forth in the table above describing the business activities of each Trustee during the past five years and other directorships held.

INTERESTED TRUSTEE

Mr. Taylor has served as a Trustee of the Trust since October 2022 and President of the Trust since August 2022, while acting as Executive Vice President, Manufacturers and Trading Trust Company, as Head of Investment Implementation and Investment Advisor Services, and previously, as Director of Investment Planning and Portfolio Implementation, Regional Investment Advisory Lead & Regional Investment Implementation Officer, and Senior Investment Advisor. His current position within the M&T Bank organization entails significant responsibilities.

Ms. Sill presently serves as Chairman of the Nominating and Governance Committee of the Trust.

The Board believes that each Trustee’s experience, qualifications, attributes and skills should be evaluated on an individual basis and in consideration of the perspective such Trustee brings to the entire Board, with no single Trustee, or particular factor, being indicative of Board effectiveness. However, the Board believes that Trustees need to have the ability to critically review, evaluate, question and discuss information provided to them, and to interact effectively with Fund management, service providers and counsel, in order to exercise effective business judgment in the performance of their duties. The Board believes that its members satisfy this standard.

Experience relevant to having this ability may be achieved through a Trustee’s educational background; business, professional training or practice; public service or academic positions; experience from service as a board member (including the Board) or as an executive of investment funds, public companies or significant private or non-profit entities or other organizations; and/or other life experiences.

To assist them in evaluating matters under federal and state law, the Independent Trustees may benefit from information provided by counsel to the Trust. The Board and its committees have the ability to engage other experts as appropriate. The Board evaluates its performance on an annual basis.

The Trust has a Nominating and Governance Committee which functions pursuant to its Charter. The Board of the Trust appoints the members of the Nominating and Governance Committee, which is composed of Gregory P. Chandler, Donald E. Foley, Nicholas A. Giordano and Valerie J. Sill, Chairman, each an Independent Trustee. The Nominating and Governance Committee is responsible for the selection and nomination for election to the full Board appropriate candidates for service as Trustees of the Trust. In addition, the Nominating and Governance Committee provides a forum for the Independent Trustees to address important issues of corporate governance for the Trust, including Trustee compensation and the Board self-evaluation, and to make appropriate recommendations to the full Board regarding sound governance practices. During the fiscal year ended April 30, 2022, the Nominating and Governance Committee met four times.

The Pricing Committee is composed of any one Independent Trustee and representatives from the Advisor.

BOARD LEADERSHIP STRUCTURE

The Board of Trustees is composed of four Independent Trustees and one interested trustee. Donald E. Foley, Independent Trustee, serves as the Chairman of the Board and presides at meetings of the Board. Mr. Foley regularly communicates with representatives of the Advisor and the Trust. Mr. Foley leads the deliberative meetings of the Independent Trustees that are held outside of the presence of management personnel. The Independent Trustees are advised at these meetings, as well as at other times, by separate, independent legal counsel. Mr. Foley may perform such other functions as may be requested by the Board from time to time. The Board believes that having a super- majority of Independent Trustees, coupled with an Independent Chairman, is appropriate and in the best interests of the Trust, given its specific characteristics.

The Trustees have the authority to take all actions necessary in connection with the business affairs of the Trust, including, among other things, approving the investment goals, policies, and procedures for the Funds. The Trust enters into agreements with various entities to manage the day-to-day operations of the Funds, including with the Advisor, the sub-advisors, the administrator, the transfer agent, the distributor, and the custodian. The Trustees are responsible for selecting these service providers, approving the terms of their contracts with the Funds, and exercising general oversight of these service providers on an ongoing basis.

BOARD OVERSIGHT OF TRUST RISK

The Board has not established a formal risk committee. However, much of the regular work of the Board and its standing Committees addresses aspects of risk oversight. At each regular Board meeting, the Advisor reports to the full Board on actual and potential risks to the

Funds and the Trust as a whole. In addition, as part of its regular quarterly reports to the Board about various matters, the Advisor reports to the Board on the various elements of risk, including investment risk, credit risk, liquidity risk and operational risk, as well as overall business risks relating to the Fund. In addition, the Audit Committee considers risks related to financial reporting and controls.
