Internal Audit

The company has established an internal audit unit that reports to the board of directors, specializing in internal audit work. Depending on the company's size, business conditions, management needs, and other relevant legal requirements, the internal audit unit is staffed with one audit manager and an appropriate number of internal audit personnel.

Audit personnel conduct regular or irregular audit operations. The audit results are compiled into audit reports and submitted regularly to the Audit Committee and the Board of Directors. This is done to ensure the continuous and effective implementation of the company's internal control system. Follow-up reports on audit findings and improvement status are prepared to confirm that relevant units have taken appropriate corrective actions.

The internal audit unit supervises various internal units within the company and its subsidiaries, requiring them to conduct annual self-assessments of the effectiveness of their internal control systems. The internal audit unit then reviews these self-assessments along with any internal control deficiencies and anomalies found by the audit unit. This information is used as a key basis for the Board of Directors and the General Manager to evaluate the overall effectiveness of the internal control system and issue an internal control system statement. The internal control system statement is announced and published on the website designated by the competent authority and included in the annual report, as required by regulations.
