Audit Committee Pre-Approval Policies and Procedures The Audit Committee has adopted a policy that requires advance approval of all audits, audit-related, tax and other services performed by the independent registered public accounting firm. The policy provides for pre-approval by the Audit Committee of specifically defined audit and non-audit services. Unless the specific service has been previously pre-approved with respect to that year, the Audit Committee must approve the permitted service before the independent registered public accounting firm is engaged to perform it. The Audit Committee has delegated to the chair of the Audit Committee authority to approve permitted services, provided that the chair reports all approvals to the Audit Committee at its next meeting. All of the fees described in the table on page 77under “Audit Fees”, “Audit-Related Fees”, “Tax Fees” and “All Other Fees” were approved by the Audit Committee.
