Moreover, we have established a department in charge of business ethics that is charged with the identification and resolution of issues pertaining to the compliance system. The Company is strongly promoting compliance management. It aims to be healthy and open, with both a culture that encourages and enforces proper ethical conduct and a system for preventing misconduct and scandals before they occur. In so doing, we will meet the expectations of investors and other stakeholders.
