107年第2季權益變動表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial data specifically showing a consolidated statement of changes in equity for the first half of the year 2018 (民國107年上半年度) and the same period in the previous year. The data includes items such as common stock, capital surplus, legal reserve, undistributed earnings, retained earnings, foreign currency translation adjustments, and total equity. The presence of actual financial figures and the focus on a half-year period indicate this is a substantive financial report for a period shorter than a full fiscal year. The document length is 3917 characters, which is relatively short but contains detailed financial tables, not just an announcement or a link to a report. Therefore, it fits the definition of an Interim / Quarterly Report (IR).

107年07月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders, including directors, chairpersons, general managers, and other key management personnel. It lists their share types, holdings at various points in time, and changes in shareholdings. The content focuses on insider share transactions and holdings disclosures. There is no indication of financial results, earnings, management discussion, or regulatory announcements beyond insider shareholding data. 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 sufficient and the content is substantive insider shareholding data, not a mere announcement or certification. Therefore, the correct classification is DIRS with high confidence.

107年07月董事會成員及持股
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings and pledged shares of company insiders, including directors, supervisors, and major shareholders. It includes specific data on share counts held at appointment and currently held, as well as pledged shares and related ratios. The document is focused on insider shareholdings and their changes, which aligns with reporting of personal share transactions or holdings by company directors and executives. There is no indication of financial results, management discussion, or other report types. The document length is about 2773 characters, which is relatively short but contains detailed insider shareholding data. Therefore, the document best fits the category of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives (insider trades).
2018-08-07 Chinese
107年7月背書保證與資金貸與
Capital/Financing Update Classification · 90% confidence The document is a financial disclosure from a listed company (台勝科) providing information about fund loans and endorsement guarantees for a specific month (July 2018, 民國107年07月). It contains tabulated financial data about loan balances and guarantees but does not include comprehensive financial statements or detailed analysis. The content is typical of a regulatory announcement about financing or capital-related information rather than a full report. Given the nature of the data (fund loans, guarantees, limits) and the short length (621 characters), this fits best under Capital/Financing Update (CAP).

107年7月營業收入
Fund Information / Factsheet Classification · 85% confidence The document is a summary report of monthly and cumulative net operating revenue figures for a company named 台勝科, with data presented for July 2018 (民國107年07月) and comparisons to the previous year. It includes percentage changes and notes on accounting standards (IFRS) and reporting practices. The document is very short (781 characters) and primarily provides financial summary 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 also does not fit categories like Earnings Release (ER) since it lacks key highlights or narrative. The document resembles a brief financial summary or factsheet. Given the brief nature and summary format, the best fitting category is Fund Information / Factsheet (FS).
2018-08-06 Chinese
107年08月內部人持股轉讓(事前)
Director's Dealing Classification · 100% confidence The document contains a table detailing a share transfer by a company director, including information about the number of shares to be transferred, transfer method, and dates. It is a report of a personal share transaction by a company director, which fits the definition of Director's Dealing (DIRS). The document is short and specific to insider share transactions, not a general financial report or announcement.
