[000004] II. Corporate Governance Status [100000] 1. General Corporate Governance Policy (a) Overall direction and key considerations of the company's corporate governance policy: The company aims to maximize shareholder value and corporate value based on customer-centric and transparent management. To this end, it pursues transparency, soundness, and stability in management, as well as balance through mutual checks between the board and management. In board operations, Article 37 of the Articles of Incorporation restricts directors with a special interest from exercising voting rights on relevant board resolutions, so as not to represent specific interests. To secure diversity and expertise on the board, candidate backgrounds are thoroughly reviewed and finally confirmed at the general meeting, preventing concentration in any particular background or profession. Regarding outside directors, per Article 29 of the Articles, at least one-third of all directors are outside directors, in compliance with Article 542-8 of the Commercial Act. Ultimately, a governance structure is built where the board, management, and outside directors achieve mutual checks and balances. (b) Unique governance features of the company: The board is the highest decision-making body composed of directors elected at the general meeting, and has authority over key corporate matters per the board regulations it has established. Currently, the board includes one outside director, representing about 33.3% of all directors, which meets the relevant legal requirement. Outside directors are external figures with independence and expertise, contributing to management efficiency and performing a board oversight role. The company has not established a separate committee for recommending outside director candidates, but the board strictly screens for disqualifying grounds under the Commercial Act before recommending qualified candidates to the general meeting.
