주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 100% confidence The document is titled '주식등의 대량보유상황보고서' which translates to 'Report on Large Shareholding Status'. It contains detailed information about share ownership percentages, changes in shareholding, related contracts, and disclosures about major shareholders and their relationships. The document references specific dates and includes detailed tables about shareholdings and contracts related to shares. This type of document corresponds to notifications about major shareholding changes or disclosures of significant share ownership levels. It is not an annual report, earnings release, or any other financial report. It is a regulatory filing specifically about major shareholding notifications. Therefore, the appropriate classification is Major Shareholding Notification (MRQ). The document length is sufficient and contains substantive data, not just an announcement or certification, so it is not RNS or RPA.
