Board of Directors

Responsible Management governed by Independent Board of Directors

Board of Directors

We ensure that the Board members are well balanced in their expertise and capability to help the Board make decisions in an efficient and strategic manner. With the election of a female independent director in 2020, who has professional knowledge in law, the Board of Directors has now become much more diversified. In 2021, an independent director was also elected as the chair of the Board, which has helped the Board gain greater independence.
