[기재정정]타인에대한채무보증결정
Capital/Financing Update Classification · 1% confidence The document is a formal corporate disclosure of a board resolution to extend and issue guarantees on behalf of an overseas affiliate (“타인에 대한 채무보증 결정”), detailing amounts, periods, related parties, and board approval. This is a financing-related transaction announcement rather than a full financial report or regulatory notice. It falls under updates on financing activities/capital structure changes, so classify as a Capital/Financing Update (CAP).

주식등의대량보유상황보고서(일반)
Major Shareholding Notification Classification · 1% confidence The document is a “주식등의 대량보유상황보고서” (Large Shareholding Report) under the Korean Capital Markets Act, detailing the number of shares held by the reporting major shareholder and related parties, changes in holdings, and contracts (e.g., exchangeable bonds). It is a statutory notification of significant share ownership changes (threshold crossing) rather than an announcement of an earnings release or financial report. This aligns exactly with the “Major Shareholding Notification” category (Code: MRQ).

임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 1% confidence The document is an insider holdings change report (‘임원ㆍ주요주주 특정증권등 소유상황보고서’) filed by an executive (정창보) showing personal stock transactions (number of shares held before/after, trades on market). This matches a Director’s Dealing report of personal share transactions by company insiders. Therefore, it should be classified as DIRS.
