주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 100% confidence The document is titled '주식등의 대량보유상황보고서' which translates to 'Report on Large Shareholding Status'. It details the shareholding status of a major shareholder, including changes in share ownership, related contracts, and voting rights. It references specific dates and share quantities, and includes detailed tables about shareholding and related contracts. This type of document corresponds to notifications about changes in significant share ownership levels, which matches the definition of 'Major Shareholding Notification' (Code: MRQ). The document is lengthy (8979 characters) and contains substantive data, not just an announcement or certification, so it is not a Regulatory Filing or Report Publication Announcement. Therefore, the correct classification is MRQ with high confidence.
