📌 Tracking the Final Decision Filing on Unfaithful Disclosure Designation

This advance notice informs that an advance notice procedure has been initiated regarding two disclosure revocations concerning subsidiaries in November 2024. Verifying whether the final outcome regarding designation or non-designation is officially published by the deadline of January 20, 2025, is important to track the final resolution of this regulatory update. The final decision can be confirmed in subsequent filings such as ‘Non-Designation as Unfaithful Disclosure Corporation’ or ‘Designation as Unfaithful Disclosure Corporation’ to be submitted around the decision deadline.
