Internal Audit
-
The Company’s internal audit is an independent unit that reports directly to the Board of Directors. In accordance with the Company's scale, business status, management requirements, and relevant legal regulations, one qualified full-time Chief Internal Auditor and one full-time Internal Audit Officer are appointed. In addition to regularly reporting audit activities to the members of the Audit Committee, the internal audit unit also attends routine Board meetings to present reports.
-
The Company has established Internal Audit Implementation Rules that clearly define the audit items, schedule, procedures, and methods. Based on the results of risk assessments, an annual audit plan is formulated. Audit personnel conduct on-site audits on a regular or ad hoc basis. The audit findings, supported by working papers and related documentation, are compiled into audit reports for review and approval. This ensures the continued effectiveness of the internal control system and serves as a basis for revising and improving internal controls. The internal control system and audit scope cover all operations of the Company and its subsidiaries.
-
The Company requires each department and subsidiary to conduct an annual self-assessment of the effectiveness of their internal control systems. The internal audit unit reviews these self-assessment reports and integrates them with the audit findings, including identified deficiencies and the status of corrective actions. These combined results serve as the primary basis for the Board of Directors and the General Manager to evaluate the overall effectiveness of the internal control system and to issue the Internal Control System Statement.
-
Upon approval, audit reports and follow-up reports are submitted to the Audit Committee members for review by the end of the month following the completion of each audit project. If internal auditors discover any material violations or incidents that may cause significant damage to the Company, a report is immediately submitted for approval, and the Audit Committee members are notified without delay.
