CORPORATE GOVERNANCE

The Board of Directors has also adopted the Code of Ethics for Chief Executive and Senior Financial Officers. These individuals are expected to avoid actual or apparent conflicts between their personal and professional relationships and make full disclosure of any material transaction or relationship that could create or appear to create a conflict of interest to the General Counsel, who will inform and seek a determination from the Chair of the Audit Committee as to whether a conflict exists and the appropriate disposition of the matter. In addition, these individuals are expected to promote the corporate policy of making full, fair, accurate and understandable disclosure in all reports and documents filed with the SEC; report violations of the Code of Ethics to the General Counsel or the Chair of the Audit Committee; and request from the General Counsel any waivers of the Code of Ethics, which shall be publicly disclosed if required by applicable law.

Any waiver of any provision of the Global Code of Conduct or the Code of Ethics for Chief Executive and Senior Financial Officers for any executive officer may be granted only by the Board of Directors. Any waiver of the Code of Conduct for Non-Employee Directors may be granted only by the disinterested directors of the Board of Directors or the Audit Committee, and any such waiver shall be promptly disclosed to the Corporation’s stockholders. The Board of Directors and the Audit Committee review whether such waivers are in the best interests of the Corporation and its stockholders, taking into account all relevant factors. In 2024, there were no waivers of (a) the Global Code of Conduct for executive officers, (b) the Code of Ethics for Chief Executive and Senior Financial Officers, or (c) the Code of Conduct for Non-Employee Directors.

The Corporation also maintains an ethics hotline to allow any employee to express a concern or lodge a complaint, confidentially and anonymously, about any potential violation of the Corporation’s Global Code of Conduct.
