Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings of company insiders, including directors, supervisors, and management, with specific numbers of shares held, pledged shares, and related information. The content focuses on insider shareholdings and changes, which is typical of a Director's Dealing report. There is no indication of financial statements, earnings data, or meeting materials. The document length is about 2935 characters, which is consistent with a detailed insider shareholding disclosure rather than a full report or announcement.

Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings of company insiders, including directors, supervisors, and executives, with specific numbers of shares held, pledged shares, and related percentages. It is a disclosure of insider shareholdings and changes, typical of a report on personal share transactions or holdings by company directors and executives. There is no indication of financial statements, earnings data, or meeting materials. The document length is relatively short (2935 characters), and it is not an announcement of a report but a direct disclosure of insider shareholdings. Therefore, the most appropriate classification is Director's Dealing (DIRS).

104年第3季大陸投資
Regulatory Filings Classification · 95% confidence The document is a detailed tabular disclosure of investment amounts, investment methods, and investment income related to the company's investments in mainland China for a specific quarter (year 104, quarter 3 in the Taiwanese calendar). It includes financial figures, investment percentages, and regulatory approval limits. The document is relatively short (1602 characters) and appears to be a regulatory disclosure of investment information rather than a full financial report or earnings release. It does not contain comprehensive financial statements or management discussion but rather specific investment data and compliance information. This type of document fits best under Regulatory Filings (RNS), as it is a regulatory disclosure that does not fit into other specific categories like Annual Report, Interim Report, or Capital Update.
