It serves as an officer certification regarding the accuracy of the company's Annual Securities Report (有価証券報告書). According to the 'CERTIFICATION RULE', documents that are primarily officer certifications or attestations should be classified as Regulatory Filings (RNS), even if they reference a specific report type, as they do not contain the actual financial statements themselves.
