주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 90% confidence The document is a detailed ‘주식등의 대량보유상황보고서(일반)’ (Report on the status of large shareholdings) filed under the Korean Capital Markets Act. It provides full disclosure of shareholdings by a major shareholder and related parties, including precise share counts, percentages, changes and contract details. This corresponds exactly to a notification of significant share ownership levels (Major Shareholding Notification).

최대주주등소유주식변동신고서
Major Shareholding Notification Classification · 98% confidence The document is a formal notification of changes in share ownership by the largest shareholder and related persons, titled “최대주주등소유주식변동신고서” (Major Shareholder Shareholding Change Report). It details pre- and post-transaction share counts, percentages, and individual insider transactions. This corresponds to a Major Shareholding Notification. Therefore, the correct classification is MRQ.

기업가치제고계획(자율공시)
Regulatory Filings Classification · 47% confidence The document is a voluntary disclosure (“자율공시”) by a Korean issuer detailing its “기업가치 제고 계획” (corporate value enhancement plan), focused primarily on dividend policy, payout targets, and related tax‐law classification as a high-dividend company. It is not a full annual or interim financial report, nor is it an investor presentation, earnings release, M&A announcement, board change, or other defined category. It also is not merely a notice pointing to an attached report (so it’s not RPA), and it does not strictly fit ‘Notice of Dividend Amount’ since it’s about policy and plan rather than setting payment records/dates. Therefore it falls into the fallback “Regulatory Filings” category.
