The company irregularly reviews these measures to comply with current laws and practical management needs.

Every quarter, the company conducts training on the regulation and rule of article 10 of the Corporate Governance Best Practice Principles for insiders, certain supervisors, and colleagues. The training includes prohibitions on trading securities using undisclosed information and reminders not to engage in stock transactions during the thirty days before the annual financial report announcement and the fifteen days before each quarterly financial report announcement. This is to effectively prevent insider trading. In the year 2025, such training has been conducted for approximately 15 individuals in each quarter.

The new directors, supervisors and managers will be educated within 3 months after taking office, and new employees will be educated by pre-employment training.
