Audit Committee Pre-Approval Policy
The Audit Committee pre-approves all audit and permissible non-audit services provided by our independent registered public accounting firm on a case-by-case basis. These services may include audit services, audit-related services, tax services and other services. Our Chief Financial Officer is responsible for presenting the Audit Committee with an overview of all proposed audit, audit-related, tax or other non-audit services to be performed by our independent registered public accounting firm. The presentation must be in sufficient detail to define clearly the services to be performed. The Audit Committee does not delegate its responsibilities to pre-approve services performed by our independent registered public accounting firm to management or to an individual member of the Audit Committee.
