公告本公司102年3月15日董事會重要決議
Board/Management Information Classification · 95% confidence The document is a company announcement from the board meeting held on 102/03/15 (Taiwan calendar year, corresponding to 2013). It reports important board resolutions including approval of the 101 fiscal year financial statements (with revenue, pre-tax profit, net profit, and EPS), amendments to company articles, and shareholder meeting rules. The document is short (759 characters) and primarily announces board decisions rather than providing a full annual report or detailed financial statements. It is not a full Annual Report (10-K) or Interim Report (IR), nor is it a Management Report (MDA) or Earnings Release (ER). The content fits best with Board/Management Information (MANG) as it announces board meeting resolutions and corporate governance changes. Therefore, the classification is MANG with high confidence.

Interim / Quarterly Report Classification · 95% confidence The document is a revenue summary report from a publicly 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 (773 characters) and primarily provides financial data for a specific month and year (民國102年02月, which corresponds to February 2013). 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) because it provides substantive financial data for a period shorter than a full fiscal year with actual financial figures and analysis notes. Therefore, the classification is IR with high confidence. Q1 2013

Regulatory Filings Classification · 95% confidence The document is a brief financial disclosure from a listed company (台勝科) reporting on the status of fund loans and endorsement guarantees for the current and previous month, including cumulative amounts and limits. It contains no detailed financial statements or analysis, nor does it mention any report publication or certification. The content is a regulatory disclosure of financial guarantees and loans, which fits best under Regulatory Filings (RNS) as it is a general compliance announcement without substantive financial report data.

Director's Dealing Classification · 100% confidence The document consists of detailed tables listing shareholdings and changes in share ownership by insiders, including directors, supervisors, and senior management. It includes data on shares held, increases, decreases, and trust shares. The content is focused on insider share transactions and holdings rather than financial results, management changes, or meeting materials. There is no indication of it being a full financial report, earnings release, or regulatory certification. The document is a report of personal share transactions by company directors and executives, fitting the definition of Director's Dealing (DIRS).

102年02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, including directors, supervisors, and senior management, showing their current holdings, pledged shares, and related information. It includes data on shareholdings by various insiders and their relationships, but does not contain financial statements, earnings data, or management discussion. The document is focused on insider shareholdings and related disclosures. This matches the definition of Director's Dealing (DIRS), which reports personal share transactions or holdings by company directors and executives. The document length is about 3,000 characters, which is consistent with a detailed insider shareholding report rather than a full financial report or announcement. Therefore, the appropriate classification is DIRS with high confidence.

Fund Information / Factsheet Classification · 95% confidence The document is a brief financial summary report showing monthly and cumulative net operating revenue figures for a company (台勝科) for a specific month (民國102年01月, which corresponds to January 2013). It includes percentage changes compared to the previous year and some explanatory notes about accounting standards and reporting practices. The document length is very short (771 characters) and contains no detailed financial statements or comprehensive analysis. It is essentially a factsheet or summary of key financial data rather than a full report or announcement of a report. Therefore, the best fitting category is Fund Information / Factsheet (FS), which covers brief summaries of key company financials and market info.
