Internal Audit

Formulation and supervision of integrity management policies.

Internal Audit Organization

The Company's Audit Office is an independent unit under the Board of Directors, responsible for examining and evaluating internal controls to ensure continuous and effective compliance with the internal control system.
The Audit Office has one audit supervisor with a designated deputy. The appointment and dismissal of the internal audit supervisor shall be approved by the Audit Committee and then submitted to the Board of Directors for resolution, with filing through the internet information system.
In addition to meeting the qualifications required by the competent authority, audit personnel continue to take professional courses related to internal audit each year to improve audit quality and capabilities. The roster of internal audit personnel and training records are filed through the internet information system before the end of January each year.

Internal Audit Operations

The internal audit unit prepares the audit plan for the following year before year-end, including monthly audit items, and submits it to the Board of Directors and Audit Committee for approval. Following the audit procedures and key points established in the Company's 'Internal Audit Implementation Rules', on-site interviews and sample testing are conducted for examination, verification, and evaluation, with working papers and related materials compiled into audit reports.
Audit reports are delivered to Audit Committee members for review before the end of the month following completion, with regular reports to the Board of Directors and Audit Committee on audit execution.
Internal audit personnel truthfully disclose any internal control deficiencies and anomalies discovered in audit reports, follow up after report approval, and regularly prepare follow-up reports to ensure all units have taken appropriate corrective measures.
The Audit Office submits the 'Internal Control System Effectiveness Assessment' for approval by more than half of all Audit Committee members.
The Audit Office annually reviews self-inspection reports from all company units and subsidiaries as required, combining these with internal audit results and improvement status to provide the Board of Directors, Chairman, and General Manager with a basis for evaluating overall internal control system effectiveness and issuing the 'Internal Control System Statement'. This statement is published in the annual report as required, and the annual internal audit plan, audit plan execution, internal control deficiencies, and improvement status are all filed on the Market Observation Post System as required.
