임원ㆍ주요주주특정증권등소유상황보고서
Major Shareholding Notification Classification · 100% confidence The document is titled '임원ㆍ주요주주 특정증권등 소유상황보고서' which translates to 'Report on Ownership Status of Specific Securities by Executives and Major Shareholders.' It includes detailed information about securities ownership, changes in holdings, and related personal and company data. The document is addressed to regulatory bodies such as the Securities and Futures Commission and the Korea Exchange, indicating it is a formal disclosure of insider holdings. This matches the definition of a Major Shareholding Notification, which involves reporting changes in significant share ownership levels. The document length is 2463 characters, which is consistent with a detailed notification rather than a full financial report or announcement. Therefore, the appropriate classification is Major Shareholding Notification (MRQ).

사외이사의선임ㆍ해임또는중도퇴임에관한신고
Board/Management Information Classification · 99% confidence The document is a formal regulatory notice titled “사외이사의 선임ㆍ해임 또는 중도퇴임에 관한 신고,” which translates to “Report on the appointment, dismissal, or mid-term resignation of outside directors.” It lists dates, names, terms, and details of newly appointed outside directors, clearly indicating changes to the company’s board. This aligns with the “Board/Management Information” category, which covers announcements of changes in the board of directors.

주주명부폐쇄기간또는기준일설정
Regulatory Filings Classification · 75% confidence The document is a short regulatory notice (403 characters) announcing the record date and registry closure period for shareholder rights determination ahead of an extraordinary general meeting.

No specific category exists for record‐date notices, so it falls under the general Regulatory Filings category (RNS).
