Throughout each fiscal year, the Audit Committee invites appropriate members of management to its meetings to provide enterprise-level reports relevant to the Audit Committee's oversight role, including adequacy and effectiveness of management reporting and controls systems used to monitor adherence to policies and approved guidelines, information systems and security over systems and data, treasury, insurance structure and coverage, tax structure and planning, worldwide disaster recovery planning and the overall effectiveness of company's operations risk management policies. The Audit Committee is generally scheduled to meet at least twice a quarter, and generally covers one or more areas relevant to its risk oversight role in at least one of these meetings.
