Part 2 Corporate Governance

Confidentiality

1. All related persons must keep the fraud information and the investigation confidential and not be disclosed to
anyone other than those who have a legitimate need to know.

2. The Investigation Report may not be disclosed to anyone in order to avoid damaging the reputation of
employees suspected but subsequently found innocent of any fraud, and to avoid potential civil liability.
3. Any employees contacted by the media, investors, or other stakeholders, must respond that “I’m not at liberty
to discuss this matter” and refer them to the Investor Relations or Public Relations Department.

In 2022, the Company has quarterly followed-up the progress of reports provided through all channels, along with
the details of investigations and measurements which had been implemented. It appears that no misconduct, fraud,
or any kinds of actions which violated the Corporate Governance Policy, have occurred.
