        <ExplanationTxt>Per PMA's Bylaws, the executive committee is authorized to exercise the following specific powers and duties on behalf of the board of trustees: (a) To enter into employment with, and to terminate the employment of, the chief executive officer (the "Director"), to negotiate and enter into employment contracts with the Director subject to final approval by the board of trustees, to annually review the performance of the Director, to determine the Director's annual compensation adjustments and benefits adjustments, to resolve all disciplinary and other issues relating to the Director's employment; (b) To review annually the performance of any other key employees and to resolve all disciplinary and other issues relating to such employees when such tasks are specifically delegated to the executive committee by the board of trustees; The Executive Committee in 2017 developed a new compensation plan and five year contract for the PMA Director. The employment contract began on March 1, 2017 and terminates on February 28, 2022. The compensation plan was developed by an ad hoc committee of the Executive Committee. The ad hoc committee was formed to develop a multi-year plan for approval by the full Executive Committee. The ad hoc committee contracted with Career Management Associates (CMA) to provide guidance as to an appropriate level of compensation. On January 13, 2017, CMA provided a report titled: "Non-Profit Executive Compensation Analysis Report." CMA's report included data compiled from the 990 forms of specific peer group organizations identified by the PMA's board, and also compiled 990 data from a broader set of peers who reported the same nonprofit classification. Using the report's guidelines, the ad hoc committee negotiated with the Director a new five-year contract that provides remuneration within the band of reasonable compensation for a similarly situated museum director. The Executive Committee approved the terms of the new employment agreement and it was accepted by the Director and signed by all parties on May 3, 2017.</ExplanationTxt>
