107年9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 endorsement guarantees for a specific month (September 2018, 民國107年09月). It contains tabulated financial data about loan balances and guarantees but is very short (621 characters) and does not include comprehensive financial statements or analysis. It appears to be a regulatory disclosure related to financing or guarantees rather than a full financial report. Given the content 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.

107年9月營業收入
Interim / Quarterly Report Classification · 85% confidence The document is a summarized revenue report for a company named 台勝科 for the period 民國107年09月 (September 2018). It contains monthly and cumulative net operating revenue figures with percentage changes compared to the previous year. The document is short (782 characters) and appears to be a periodic financial summary rather than a full financial report. There is no indication of detailed financial statements, management discussion, or audit information. It is not an announcement of a report publication but a direct data disclosure. Given the nature of the content—monthly and cumulative revenue figures with explanations—it fits best as an Interim / Quarterly Report (IR), which covers financial data for a period shorter than a full fiscal year.

107年09月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document is a detailed tabular disclosure of shareholdings by insiders, including directors, senior management, and major shareholders. It lists share counts, changes in holdings, and related notes. The content focuses on insider share transactions and holdings rather than financial results, governance policies, or meeting materials. There is no indication of it being a full annual or quarterly report, earnings release, or management discussion. The document is not a proxy statement or voting result announcement. It is a report of personal share transactions and holdings by company directors and executives, consistent with the definition of Director's Dealing filings.

107年09月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings and stock pledges by company insiders, including directors, supervisors, and senior management. It lists their shareholdings, pledged shares, and related information. The content focuses on insider share transactions and holdings rather than financial results, management changes, or meeting materials. There is no indication of a report or announcement of voting results, nor is it a regulatory compliance filing or a financial report. The document fits the definition of a Director's Dealing report, which covers personal share transactions by company directors and executives (insider trades). The document length is 2776 characters, which is consistent with a detailed insider shareholding disclosure rather than a full report or announcement. Therefore, the appropriate classification is Director's Dealing (DIRS).

Major Shareholding Notification Classification · 95% confidence The document is a statistical table showing the shareholding situation of overseas and mainland China investors, including changes in shareholding numbers and reasons such as capital reduction. It includes detailed shareholding figures before and after changes, but does not contain financial statements, management discussion, or report narratives. The document is a notification of changes in significant share ownership levels, fitting the definition of a Major Shareholding Notification (MRQ). The document length is short and focused on shareholding data, not a full report or announcement of a report publication.

107年09月內部人持股未轉讓(事前)
Director's Dealing Classification · 100% confidence The document is a short tabular report showing a director's personal share transactions, including details such as the number of shares held, shares not transferred, and reasons for not transferring shares. It specifically mentions '董事本人' (director himself) and shareholding details. The document length is only 432 characters, indicating it is a brief notification rather than a full report. This matches the definition of a Director's Dealing report, which reports personal share transactions by company directors and executives (insider trades).
