102年05月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings and changes in share ownership by insiders, including directors, supervisors, and senior management of the company. It includes data on shares held at appointment, changes during the month, and current holdings, with specific mention of insider categories and their share transactions. There is no indication of financial statements, earnings data, or meeting materials. The content matches the description of a Director's Dealing report, which reports personal share transactions by company directors and executives (insider trades). The document length is sufficient and contains substantive data, not just an announcement or certification. Therefore, the appropriate classification is Director's Dealing (DIRS).

102年05月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed tabular disclosure of shareholdings by insiders, including directors, supervisors, and senior management, with specific numbers of shares held, pledged shares, and related information. It includes data about internal persons' shareholdings and their relationships, but does not contain financial statements, earnings data, or management discussion. The document is not a report or announcement of a meeting, nor is it a legal or regulatory filing about changes in management or capital structure. It is a notification of insider shareholdings, which corresponds to the category of Director's Dealing (DIRS), as it reports personal share transactions or holdings by company directors and executives. The document length is 3027 characters, which is consistent with a detailed insider shareholding report rather than a brief announcement or a full financial report.

102年5月營業收入
Interim / Quarterly Report Classification · 90% confidence The document is a summarized revenue report from a listed company (台勝科) showing monthly and cumulative net operating revenue figures compared to the previous year. It includes explanations about accounting standards (IFRS) and reporting practices. The document is short (774 characters) and primarily presents financial data for a specific month and year (May 2013, 民國102年05月). It does not contain a full annual or quarterly report, nor does it appear to be an announcement or certification. The content fits the definition of an Interim / Quarterly Report (IR) as it provides substantive financial data for a period shorter than a full fiscal year with analysis of revenue changes. Q1 2013

102年5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, with all values reported as zero. The content is brief (602 characters) and consists of tabular data on financial guarantees and loans, without any narrative, financial statements, or management discussion. It does not contain quarterly or annual financial results, nor does it announce any voting results, management changes, or legal matters. The document is a regulatory disclosure of financial status related to guarantees and loans, typical of a regulatory filing for compliance purposes. Given the short length and nature of the content, it fits best under Regulatory Filings (RNS) as a general compliance announcement rather than a full financial report or other specific category.

The document is brief (565 characters) and does not contain any financial statements, detailed analysis, or report attachments.

102年第1季現金流量表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial data including cash flow statements for specific fiscal quarters (e.g., 102年第1季, which corresponds to Q1 of the year 2013 in the Taiwanese calendar).
