Director's Dealing Classification · 76% confidence The document is a disclosure of shareholdings and pledged share counts for company insiders (directors, managers, independent directors, etc.) as reported on the Taiwan Market Observation Post System (“公開資訊觀測站”). It itemizes “選任時持股” (shareholding at appointment), “目前持股” (current shareholding), pledge amounts, and related insider categories. This is not an earnings announcement, dividend notice, or AGM material. It fits the definition of an insider share transaction/holding report (Director’s Dealing). Therefore, it should be classified under DIRS.
