 practices and internal controls).

Based on its evaluation, the Audit and Risk Committee believes that Deloitte is independent and well-qualified to serve as the Company’s independent auditor in 2025.

The Audit and Risk Committee also reviews the performance of Deloitte’s lead audit partner, and the Audit and Risk Committee and its Chair oversee the rotation of Deloitte’s lead audit partner and are involved in the selection and approval of the lead audit partner. The lead audit partner rotates every five years in accordance with regulatory requirements. In addition, the Audit and Risk Committee is responsible for reviewing and pre-approving audit and non-audit services and related fees for the independent auditor.

Although ratification is not required by our Bylaws or otherwise, the Audit and Risk Committee is submitting the selection of Deloitte to shareholders as a matter of good corporate governance. If the shareholders fail to ratify the appointment of Deloitte, the Audit and Risk Committee will consider this in its selection of auditor for the following year. A representative from Deloitte will attend the Annual Meeting and will have the opportunity to make a statement and respond to appropriate questions.
