The Committee Chair determines the number, time, place and agenda of the Audit Committee meetings. The Committee meets not less than four times a year. At least quarterly, the Committee meets separately with management, with the internal auditors and with the independent registered public accountant and may meet with the Corporation's internal auditors and/or independent registered public accountant without management present whenever the Committee deems it appropriate. After each meeting, the Committee reviews with the Board any issues that arose with respect to the quality or integrity of the Corporation's financial statements, the Corporation's compliance with legal or regulatory requirements, the performance and independence of the independent registered public accountant or the performance of the internal audit function.
