Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings and changes in share ownership by insiders, including directors, executives, and their related parties. It includes data on shares held, increases, decreases, and trust shares. The content is focused on insider share transactions and holdings rather than financial results, management changes, or other corporate events. There is no indication of it being a full financial report, earnings release, or management discussion. The document is not a brief announcement but a detailed insider shareholding report.

109年08月董事會成員及持股
Director's Dealing Classification · 95% confidence The document contains detailed tabular data about shareholdings of company insiders, including directors and senior management, with specific numbers of shares held, pledged shares, and related information. It is focused on insider shareholdings and their changes, not on financial results, management changes, or voting results. The document length is about 3,075 characters, which is relatively short but contains substantive data on insider holdings. This matches the definition of Director's Dealing (DIRS), which reports personal share transactions by company directors and executives. There is no indication that this is an announcement of a report or a certification, so it is not Regulatory Filings (RNS) or Report Publication Announcement (RPA). Therefore, the best classification is DIRS.
