Prevention of Insider Trading Operational Overview

  • Preventing insider trading
    In order to implement corporate governance and prevent insider trading, the Company has established internal regulations prohibiting insiders from trading in securities using unpublished information in the market. The regulations include controls on stock trading by insiders from the date they become aware of the contents of the Company's financial reports or related results, including (but not limited to) a prohibition on directors trading their shares during the closed periods of 30 days prior to the announcement of the annual financial report and 15 days prior to the announcement of each quarterly financial report.
  • Control measures
    E-mail or notification letters are sent to directors and insiders before the closed periods for the annual and quarterly financial report announcements, to avoid inadvertent violation of these regulations by trading in the Company's shares.
  • Education and awareness on the prevention of insider trading
  • From time to time, directors and insiders are notified by e-mail or notification letter of the Taiwan Stock Exchange's letter, "Common Types of Insider Shareholding Change Filings in Violation of the Securities and Exchange Act".
  • When directors take office upon the annual re-election of directors, the following regulatory guidance materials are provided to them: "Handbook on Directors and Supervisors Regulations", "Securities Market Regulations for Listed Companies, Their Directors, Supervisors, and Substantial Shareholders", "Handbook on Independent Directors Regulations", and "Laws and Regulations Related to Changes in Shareholdings of Insiders of the Company and Matters of Note for Implementation".
