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 period (February 2018, 民國107年02月). It includes comparative data with the previous year and percentage changes. The document is short (777 characters) and primarily provides financial summary data without detailed financial statements or management discussion. It does not appear to be a full annual or interim report, nor an earnings release with key highlights. It is more of a regulatory or public disclosure of revenue figures. Given the short length and nature, it fits best as a Regulatory Filing (RNS) which is a fallback category for miscellaneous filings that do not fit other specific categories.

107年2月背書保證與資金貸與
Regulatory Filings Classification · 90% confidence The document is a financial disclosure from a listed company (台勝科) providing specific data on fund lending balances and endorsement guarantees for a particular month (February of the 107th year in the ROC calendar, which corresponds to 2018). The content is tabular and quantitative but very brief (621 characters), focusing on financial data related to loans and guarantees. It does not contain comprehensive financial statements or detailed analysis typical of an Annual Report (10-K) or Interim Report (IR). It also does not announce a report publication or voting results, nor does it discuss management changes or legal matters. Given the nature of the data and the brevity, this fits best as a Regulatory Filing (RNS), which covers general regulatory announcements and compliance documents that do not fit other categories.

107年1月背書保證與資金貸與
Capital/Financing Update Classification · 85% confidence The document is a financial disclosure from a listed company (台勝科) providing information about fund lending balances and endorsement guarantees for a specific month (January of the 107th year in the ROC calendar, which corresponds to 2018). The content is tabular and quantitative but very brief (621 characters), focusing on financial data related to capital lending and guarantees. It does not contain comprehensive financial statements or detailed analysis typical of an Interim/Quarterly Report (IR) or Annual Report (10-K). It is also not an announcement of a report publication or a certification. Given the nature of the data (fund lending and guarantees), this fits best under Capital/Financing Update (CAP), which covers updates on company financing activities or capital structure changes. The document is too short and specific to be a full financial report but provides substantive financial data related to financing activities.

107年1月營業收入
Regulatory Filings Classification · 95% confidence The document is a summarized revenue report for a company named 台勝科 for the month of January in 民國107年 (2018). It contains monthly and cumulative net operating revenue figures, percentage changes compared to the previous year, and notes on accounting standards (IFRS) and reporting requirements. The document is very short (779 characters) and primarily provides a brief financial summary without detailed financial statements or analysis. 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 into categories like Earnings Release (ER) because it lacks key highlights or narrative commentary. The document is more of a regulatory or compliance filing providing summarized financial data. Given the short length and nature, it is best classified as a Regulatory Filing (RNS), which is the fallback category for miscellaneous filings that do not fit other specific categories.

107年01月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings and changes in shareholdings by insiders, including directors, supervisors, general managers, and other key personnel. It includes data on stock types, share counts at different times, increases and decreases in holdings, and notes on identities and roles. The content is focused on insider share transactions and holdings disclosures. There is no indication of financial statements, earnings data, meeting materials, or legal proceedings. The document is not a report or announcement of a report but a detailed insider shareholding disclosure. 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 consistent with insider shareholding disclosures rather than other categories.
