Internal Audit
Operation
The audit unit conducts assignments based on its annual plan, and provides results, including
working papers and related documents, compiled into reports and presented to the Chairman.
These reports are presented on a quarterly basis until improvements are achieved. The audit
manager must attend board meetings to report on results and findings.
All units and subsidiaries are required to conduct self-assessments every year, which are
then reviewed by the audit unit. Along with the aforementioned results and improvements,
this information is provided to the Board of Directors and the CEO for assessing the
effectiveness of company overall status, and is also serves as evidences for examining the
internal control system.
All reports, including the annual plan, results and findings, are documented according to the
prescribed format through an internet-based information system for reference.
