Duties of the Company’s Audit & Supervisory Board Members included attendance at Board of Directors meetings, monitoring the status of supervising execution of Director duties, and stating opinions when recognized as necessary. In addition, the decision-making process for important Group matters and the conditions of discussion at important meetings were checked, and the status of execution of duties by the President and Chief Executive Officer, Presidents of the operating companies, and functional top management was monitored. Audit & Supervisory Board Members participated in the quarterly PHD ERM Committee meeting, and attended as observers at the quarterly PHD Internal Audit Committee meeting which is the controlling institution for internal audit functions. In addition to receiving reports of the results of audits and other information from the internal auditing group, the Audit & Supervisory Board Members, internal auditing group, and Accounting Auditors all met together to exchange information on matters such as risk assessments and plans for visits at the start of the year, as well as changes in the audit contents, identified items, and risk assessments, and engaged in other audit and supervisory activities intended to strengthen Group governance.

At the Audit & Supervisory Board meetings, based on the system of independent action, Audit & Supervisory Board Members who have different expertise and knowledge openly discuss the contents of the above audit and supervisory activities, and form opinions and other information to be delivered to the Board of Directors and executive divisions. In order to continually improve the effectiveness of audit and supervisory activities, the Audit & Supervisory Board conducts an evaluation of Audit & Supervisory Board effectiveness at the end of each fiscal year. In addition to a quantitative evaluation of effectiveness based on a total of 40 evaluation items from perspectives such as action based on Corporate Governance Code, the effectiveness evaluation identified specific issues proposed by each Audit & Supervisory Board Member, and worked to identify items for improvement. Issues and improvements proposed by Audit & Supervisory Board Members are discussed and the action to be taken is decided. The results are applied to the Audit Plan for the following fiscal year.

In fiscal 2026, based on the results of the effectiveness evaluation conducted at the end of fiscal 2025, when interviewing the President, Presidents of operating companies, and others regarding the status of duties execution at meetings of the Audit & Supervisory Board, continue to receive reports focused on the subjects proposed in advance by the Audit & Supervisory Board, then secure sufficient time to focus on exchange of opinions and questioning in order to make discussions more effective. Senior Audit & Supervisory Board Members shall interview the Audit & Supervisory Board Members and audit & supervisory officers of operating companies regarding matters including the status of measures to prevent recurrence of incidents of irregularities and misconduct, quality-related issues, occupational accidents, and fires. After sharing information with the Outside Audit & Supervisory Board Members, confirm the existence of any issues, and if instructions are necessary, provide feedback to the Audit & Supervisory Board Members and audit & supervisory officers of operating companies. Furthermore, Outside Audit & Supervisory Board Members accompanied visiting audits conducted by Audit & Supervisory Board Members, and implemented measures such as conducting audits of operating conditions from wide-ranging perspectives, working to improve the effectiveness of the Audit & Supervisory Board.
