104年9月營業收入
Regulatory Filings Classification · 90% confidence The document is a revenue summary report for a company named 台勝科, showing monthly and cumulative net operating revenue figures compared to the previous year. It includes notes on accounting standards (IFRS) and reporting practices. The document is very short (776 characters) and primarily provides summarized financial data 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 categories like Earnings Release or Investor Presentation, as it lacks narrative or strategic content. Given the brevity and nature of the content, it is best classified as a Regulatory Filing (RNS), which is a fallback category for miscellaneous regulatory announcements and compliance documents that do not fit other specific categories.

104年08月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings of insiders, including directors, supervisors, general managers, and other key personnel. It shows their stock ownership, changes in holdings, and related notes. The content is focused on insider share transactions and holdings rather than financial results, management changes, or other corporate events. There is no indication of a full financial report, earnings release, or meeting materials. The document is a report of personal share transactions and holdings by company directors and executives, which fits the definition of Director's Dealing (DIRS). The document length is sufficient and contains substantive data, not just an announcement or certification.

104年08月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders and related parties of the company 台勝科, including directors, supervisors, and management. It lists the number of shares held, pledged shares, and related ratios. There is no indication of financial statements, earnings data, or management discussion. 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. The document length is about 3,080 characters, which is relatively short and focused on insider shareholding data. This matches the definition of Director's Dealing (DIRS) filings, which report personal share transactions by company directors and executives. Therefore, the appropriate classification is DIRS.

104年8月營業收入
Interim / Quarterly Report Classification · 95% confidence The document is a revenue summary report from a listed company (台勝科) showing monthly and cumulative net operating revenue figures with comparisons to the previous year. It includes notes on accounting standards (IFRS) and reporting practices. The document length is short (778 characters) and it primarily provides financial data for a specific month and year (August 2015, 民國104年08月). This matches the characteristics of an Interim / Quarterly Report (IR) as it contains substantive financial data for a period shorter than a full fiscal year. It is not an announcement or a brief summary but actual financial figures and explanations, so it is not RPA or RNS. Therefore, the best classification is IR (Interim / Quarterly Report).

104年8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 lending balances and endorsement guarantees for a specific month (August of the 104th year of the Republic of China calendar, which corresponds to 2015). The content is numerical and relates to financial status but is very brief (620 characters) and does not contain comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure of financial data rather than a full report or announcement of a meeting or voting results. Given the nature and brevity, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

更正本公司104年6月資金貸與明細表申報資料
Regulatory Filings Classification · 95% confidence The document is a short announcement correcting previously submitted financial data related to a loan detail report for June 2015 (104 year in ROC calendar). It is issued by the company and uploaded to a public information observation station. The content is a correction notice about a funding loan amount mistakenly omitted and now re-uploaded. There is no detailed financial report, no full annual or interim report, no earnings release, no management discussion, no audit report, and no other substantive financial data. The document is brief (649 characters) and serves as a regulatory announcement correcting prior disclosure. Therefore, it fits best under Regulatory Filings (RNS) as a general regulatory announcement and correction notice.
