104年11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 specific data on share counts and relationships but does not contain financial statements, earnings data, or report narratives. The document is relatively short (3080 characters) and focuses on insider shareholdings rather than financial results or corporate governance policies. This type of document aligns with the definition of Director's Dealing (DIRS), which reports personal share transactions or holdings by company directors and executives. There is no indication that this is an announcement of voting results, a report publication, or a regulatory filing. Therefore, the best classification is DIRS.

104年11月營業收入
Interim / Quarterly Report Classification · 85% confidence The document is a summarized revenue report from a listed company (台勝科) showing monthly and cumulative net operating revenue figures for a specific month and year (民國104年11月, which corresponds to November 2015). It includes comparative figures from the previous year and percentage changes. The document is short (779 characters) and appears to be a periodic financial summary rather than a full financial report. It does not contain detailed financial statements or comprehensive analysis typical of an Interim/Quarterly Report (IR) or Annual Report (10-K). It also does not fit other categories like earnings release or investor presentation. Given the nature of the data and the format, this is best classified as an Interim / Quarterly Report (IR), as it provides substantive financial data for a period shorter than a full fiscal year.

104年11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 (November of the 104th year of the Republic of China calendar, which corresponds to 2015). The content is tabular and focuses on financial data related to loans and guarantees, but it is very brief (620 characters) and does not contain comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure or compliance update rather than a full financial report or announcement of a meeting or vote. Given the short length and nature of the data, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

104年第3季海外子公司投資
Interim / Quarterly Report Classification · 90% confidence The document is a financial disclosure related to investment in overseas subsidiaries, showing investment amounts, shareholding percentages, and recognized investment gains or losses for a specific period (104th year, 3rd quarter). It contains detailed financial data about investments and their valuation, which is typical of interim or quarterly financial reporting. The document length is short (644 characters), but it contains substantive financial data, not just an announcement or certification. There is no indication that this is a full annual report or an earnings release summary. Therefore, the document fits best as an Interim / Quarterly Report (IR).

104年第3季現金流量表
Interim / Quarterly Report Classification · 95% confidence The document contains a detailed consolidated cash flow statement for the third quarter of the fiscal year 104 (Taiwan calendar), which corresponds to a quarterly period. It includes actual financial data such as cash flows from operating, investing, and financing activities, with specific amounts and comparative figures from the previous year. The document length is 2187 characters, which is relatively short but contains substantive financial data, not just an announcement or a certification. The presence of detailed financial statements for a period shorter than a full fiscal year indicates this is an Interim / Quarterly Report (IR).

104年第3季綜合損益表
Interim / Quarterly Report Classification · 95% confidence The document contains a consolidated comprehensive income statement with detailed financial figures for the third quarter of the year 104 (Taiwan calendar, corresponding to 2015) and year-to-date figures. It includes revenue, costs, operating profit, net profit, and earnings per share data. The presence of actual financial data and the quarterly period covered indicates this is a financial report for a period shorter than a full fiscal year. The document length is 3248 characters, which is sufficient to contain substantive financial data, not just an announcement or summary. There is no indication that this is an annual report or a certification or announcement of a report. Therefore, the document is best classified as an Interim / Quarterly Report (IR).
