임원ㆍ주요주주특정증권등소유상황보고서
Director's Dealing Classification · 92% confidence The document is a report titled “임원ㆍ주요주주 특정증권등 소유상황보고서,” filed with the Financial Services Commission and Korea Exchange. It details an executive’s (and major shareholder’s) holdings, changes in share counts, acquisition dates, security types and ratios. This matches an insider dealing/ownership report rather than a threshold-based major shareholding notification. Therefore, it should be classified as a Director’s Dealing (insider trades) filing.
