Our Audit Committee has a written charter. Under it, our Audit Committee assists our Board in fulfilling its oversight responsibilities by overseeing and monitoring our accounting, financial and external reporting policies and practices; the integrity of our financial statements; the independence, qualifications and performance of our independent auditor; the performance of our internal audit function; the management information services and operational policies and practices that affect our internal control; our compliance with legal and regulatory requirements; and the preparation of our Audit Committee's report included in our proxy statements. In discharging its duties, our Audit Committee has the authority to retain independent legal, accounting and other advisors.
