公告本公司106年3月17日董事會重要決議
Board/Management Information Classification · 95% confidence The document is a company announcement from the board meeting held on 106/03/17 (Taiwan calendar year 106 corresponds to 2017). It reports important board resolutions including approval of the 105 fiscal year financial statements (annual results), earnings per share, and amendments to company bylaws and procedures. The document is short (765 characters) and primarily serves as a notification of board decisions rather than the full annual report itself. It does not contain detailed financial statements or comprehensive analysis. Therefore, it is best classified as a Board/Management Information (MANG) filing, which covers announcements of board decisions and management changes or resolutions.

Director's Dealing Classification · 95% confidence The document is a detailed tabular disclosure of shareholdings by insiders, including directors, supervisors, general managers, and other key personnel. It lists their shareholdings, changes in shares held, and related notes. The content focuses on insider share transactions and holdings, which is typical of a Director's Dealing report. There is no indication of financial statements, earnings, management discussion, or other report types. The document length is substantial and contains actual data, not just an announcement or certification. Therefore, the document fits best under the category of Director's Dealing (DIRS).

106年02月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed disclosure of shareholdings by insiders and related parties of the company 台勝科 (Taiwan Semiconductor). It lists the number of shares held by directors, supervisors, and senior management, including pledged shares and shares held by spouses or minors. The document is structured as a table with titles such as '董事長本人' (Chairman), '副董事長' (Vice Chairman), '董事' (Director), '監察人' (Supervisor), and other management roles, along with their shareholdings. There is no indication of financial statements, earnings data, or management discussion of financial results. The document is not a report of voting results, nor is it an announcement of changes in board or management personnel. It is a disclosure of insider shareholdings, which corresponds to the category of Director's Dealing (DIRS), as it reports personal share transactions or holdings by company directors and executives. The document length is 3080 characters, which is relatively short but contains substantive insider shareholding data rather than just an announcement or certification. Therefore, the best fitting classification is DIRS.

106年03月內部人持股轉讓(事前)
Director's Dealing Classification · 100% confidence The document contains tabular data about share transfers by an insider (監察人本人) of a company, including details such as transfer methods, share quantities, and dates. It reports on personal share transactions by company directors or executives. There is no indication of financial results, management discussion, or regulatory announcements beyond insider share dealings. This matches the definition of Director's Dealing (DIRS). The document length is short but contains detailed insider transaction data, not just an announcement or certification, so it is not RNS or RPA.

106年2月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a brief financial disclosure from a company (台勝科) providing information about fund loans and guarantees for a specific month (February 2017). It contains tabulated financial data but is very short (620 characters) and does not include comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure of financial status related to loans and guarantees rather than a full report or announcement of a meeting or voting results. Given the nature and length, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

106年2月營業收入
Fund Information / Factsheet Classification · 85% confidence The document is a revenue summary report from a listed company (台勝科) showing monthly and cumulative net operating revenue figures compared to the previous year. It includes explanations about accounting standards (IFRS) and reporting practices. The document is short (773 characters) and primarily provides financial summary data for a specific month and year (民國106年02月, which corresponds to February 2017). It does not contain comprehensive financial statements or detailed analysis typical of an Interim/Quarterly Report (IR). Instead, it is a brief financial summary report focusing on revenue figures. Given the nature and length, this fits best as a Fund Information / Factsheet (FS), which is a brief summary of key company financials and market info.
