2. Why IRISO set up the Audit and Supervisory Committee?

To achieve sustainable growth and increase medium-and long-term business value by following IRISO philosophy of "100-year company that creates customer value," several outside directors were appointed. They have been engaged in improving corporate governance to achieve transparency, fairness, and promptness in decision-making.

To improve the supervisory function of the Board of Directors and accelerate decision-making, IRISO recently deemed that an Audit and Supervisory Committee would be suitable for its institutional design and thus set up the Audit and Supervisory Committee with the approval of the General Meeting of Shareholders on June 26, 2018.

In addition, the Nominating Committee and Remuneration Committee as voluntary advisory bodies to the Board of Directors was set up when the Board of Directors meeting was held on June 26, 2018.

The Nominating Committee and Remuneration Committee aim at ensuring independent outside directors effectively involve and give advices for decisions made on business matters such as nominations of directors and executive remuneration, increasing the transparency and objectivity of the decision-making process of the Board of Directors, as well as improving corporate governance.
