106年11月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings and pledged shares of company insiders, including directors, supervisors, and senior management. It lists their current holdings, pledged shares, and related party holdings. The document also includes notes about the absence of certain managerial positions and clarifications on share counts. There is no financial performance data, no discussion of financial results, no meeting materials, no voting results, no legal proceedings, no capital changes, and no earnings announcements. The content is focused on insider shareholdings and related disclosures. This matches the definition of Director's Dealing (DIRS), which covers reports of personal share transactions or holdings by company directors and executives (insider trades). The document length is about 3,078 characters, which is consistent with a detailed insider shareholding report rather than a full financial report or announcement. Therefore, the appropriate classification is DIRS with high confidence.

106年11月營業收入
Regulatory Filings Classification · 90% confidence The document is a revenue summary report from a listed company (台勝科) showing monthly and cumulative net operating revenue figures for a specific month and year (民國106年11月, which corresponds to November 2017). It includes percentage changes compared to the previous year and notes about accounting standards (IFRS) and reporting requirements. The document is very short (780 characters) and contains only summarized financial data without detailed financial statements or management discussion. It does not appear to be a full financial report like an Annual Report (10-K) or Interim Report (IR). It is also not an announcement of a report publication or a certification. The content fits best as a Regulatory Filing (RNS) because it is a general regulatory announcement of financial data without the depth or format of a formal financial report or earnings release. Therefore, the classification is Regulatory Filings (RNS) with high confidence.

106年11月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a financial disclosure from a listed company (台勝科) providing information about fund loans and guarantee endorsements for a specific month (November of the 106th year in the Republic of China calendar, which corresponds to 2017). The content is tabular and quantitative but very brief (621 characters), focusing on loan balances and guarantee information without detailed financial statements or analysis. It does not contain comprehensive financial results or management discussion. It is a regulatory disclosure of financial status related to loans and guarantees, typical of a regulatory filing rather than a full report or announcement. Given the short length and nature of the data, it fits best under Regulatory Filings (RNS) as a general compliance disclosure rather than a full financial report or announcement.

106年11月內部人持股轉讓(事前)
Director's Dealing Classification · 100% confidence The document contains detailed information about share transactions by an insider (監察人本人, meaning supervisor or director) involving specific share quantities, transfer methods, and dates. It lists the insider's name, company code, and shareholding changes. This matches the definition of Director's Dealing filings, which report personal share transactions by company directors and executives. The document is not a general regulatory announcement, nor is it a report or announcement of a report. It specifically details insider share transactions, so the correct classification is DIRS.

The presence of full financial statements, notes, and auditor's opinion indicates this is a full annual financial report.
