주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 100% confidence The document is a '주식등의 대량보유상황보고서' (Report on Large Shareholding), which is a standard regulatory filing in South Korea under the Capital Markets Act (Article 147). This document discloses significant ownership stakes (5% rule) by major shareholders and related parties. Since it does not fit into specific categories like 'Director's Dealing' (which is for individual trades) or 'Major Shareholding Notification' (which is a specific category for threshold crossings), and given that 'RNS' serves as the fallback for regulatory filings that do not fit other specific categories, it is classified as RNS.
