Director's Dealing Classification · 95% confidence The document contains detailed tabular data about shareholdings of company insiders, including directors, chairpersons, and executives, with specific numbers of shares held, changes in holdings, and related notes. The content focuses on personal share transactions and holdings by company directors and executives, including shares held under their names and those held under others' names. There is no indication of financial statements, earnings data, meeting materials, or regulatory announcements. The document is not a report or announcement of a report but a detailed disclosure of insider shareholdings. This matches the definition of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives (insider trades). The document length is substantial and contains actual data, not just a notice or certification. Therefore, the appropriate classification is DIRS with high confidence.

114年5月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a brief financial disclosure from a listed company, providing information on loan balances and endorsement guarantees for the current and previous months. It contains tabulated financial data but is very short (616 characters) and does not include comprehensive financial statements or detailed analysis.
