Audit Committee Pre-Approval Policy

The Audit Committee must pre-approve any audit or permissible non-audit services. The Audit Committee pre-approves all audit and permissible non-audit services provided by the independent auditors prior to its engagement of such services. These services may include audit services, audit-related services, tax services and other services. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. The independent auditors and management are required to periodically report to the Audit Committee regarding the extent of services provided by the independent auditors in accordance with this pre-approval, and the fees for the services performed to date. All audit and non-audit services were pre-approved by the Audit Committee.
