Pre-Approval Policies and Procedures.

The Audit Committee (Audit Committee) reviews all requests for proposed audit or permitted non-audit services to be provided by the
Companys independent auditor under the Audit Committees Protocol for Approval of Audit and Permitted Non-Audit Services (the Protocol). Under the Protocol, the Audit Committee annually reviews and pre-approves recurring audit
and non-audit services that are identifiable for the coming year. The Protocol also requires that any audit or non-audit services that are proposed during the year be approved by the Audit Committee, or by a member of the Audit Committee appointed
by the Audit Committee and acting on its behalf.

All audit and non-audit services provided to the Company by Ernst & Young LLP have
been pre-approved by the Audit Committee pursuant to the Protocol. The Audit Committee has reviewed the magnitude and nature of these services to ensure that they are compatible with maintaining the independence of the external auditor.
