104年03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. It includes data on shares held at appointment, changes during the month, and current holdings, with specific mention of identities such as chairman, directors, supervisors, and financial department heads. This type of document is characteristic of a Director's Dealing report, which discloses personal share transactions by company directors and executives. There is no indication of it being a full financial report, earnings release, or other types of filings. The document length is sufficient and contains substantive data, not just an announcement or certification. Therefore, the appropriate classification is Director's Dealing (DIRS).

104年03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 senior management. It lists the number of shares held, pledged shares, and related percentages. 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 the category of Director's Dealing (DIRS), which covers reports of personal share transactions 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 best classification is DIRS.

104年3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 details about fund lending balances and endorsement guarantees for a specific month (March of the 104th year in the Republic of China calendar, which corresponds to 2015). The content is tabular and quantitative but very brief (618 characters), focusing on financial data related to capital lending and guarantees rather than a full financial report or announcement. It does not contain comprehensive financial statements or management discussion, nor does it announce a report publication or voting results. Given the nature of the data and the short length, it fits best as a Regulatory Filing (RNS), which is a general category for miscellaneous regulatory disclosures that do not fit other specific categories.

104年3月營業收入
Financial Supplement Data Classification · 85% confidence The document is a summarized revenue report for a company named 台勝科 for the period 民國104年03月 (March 2015). It contains monthly and cumulative net operating revenue figures with percentage changes compared to the previous year. The document is short (772 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 comprehensive analysis. It is not an earnings release or interim report because it lacks key highlights or substantive financial data beyond revenue figures. It is also not an announcement of a report publication or regulatory filing. Given the nature of the data (monthly revenue summary) and the short length, the best fit is a Financial Supplement Data (XLSX) type, which covers supplementary financial data summaries, even though this is not an Excel file, the content matches the type of brief financial data summary. However, since the document is a brief revenue summary without detailed financial statements, the closest category is Financial Supplement Data (XLSX). Confidence is high due to clear financial data and short length.

103年度財務比率
Fund Information / Factsheet Classification · 90% confidence The document contains a table of financial ratios and metrics for fiscal years 101, 102, and 103 (likely referring to Taiwanese calendar years). The content includes financial structure, solvency, operating ability, profitability, and cash flow ratios. The document length is only 952 characters, which is quite short and does not contain detailed financial statements or narrative analysis. It appears to be a brief financial summary or factsheet rather than a full annual or interim report. There is no indication of it being a presentation, call transcript, or regulatory filing. Given the concise nature and focus on key financial metrics, this fits best as a Fund Information / Factsheet (FS) type document.
2015-03-30 Chinese
103年第4季現金流量表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial data, specifically a cash flow statement for the fiscal year 103 (2014) and the previous year 102 (2013) in New Taiwan Dollars. It includes line items such as net income before tax, depreciation, amortization, changes in working capital, investing and financing cash flows, and ending cash balances. The presence of comprehensive financial statements and substantive financial data for a specific fiscal period indicates this is a financial report rather than a brief announcement or certification. The document length is 2181 characters, which is relatively short, but the content is actual financial data, not just a notice or link to a report. Given the detailed financial data for a full fiscal year, this aligns best with an Interim / Quarterly Report (IR) since it is for a quarter (4th quarter) and not a full annual report (10-K). There is no indication this is an annual report or audit report. Therefore, the classification is IR with high confidence.
