Management of Conflict of Interest (COI)
Kyoto Fusioneering Ltd. diligently implements effective management practices to prevent conflicts of interest in activities that require public interest, neutrality, and transparency, such as industry-academia-government collaboration.
The Company’s Board of Directors, which includes external directors, serves as the highest decision-making authority. Article 6.3 of the Board of Directors Regulations outlines the process for approving competitive transactions and conflict of interest transactions involving directors. Furthermore, Article 13.4 of the Board of Directors Regulations mandates the submission of reports on competitive transactions, conflict of interest transactions, and conflicts of interest involving directors. These requirements are explicitly stated in Article 13(4) of the Board of Directors’ Regulations, which specifies the need for approval and reporting of such transactions and conflicts of interest.
In cases where any of our directors or employees assume roles in external committees or similar bodies that may pose a conflict of interest with our activities, we make a commitment to individually verify the conflict of interest policy with the relevant external committee secretariat and adhere to it.
