104年03月董事會成員及持股
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings of company insiders, including directors, supervisors, and management, with specific numbers of shares held, pledged shares, and related percentages. It is a disclosure of insider shareholdings and their changes. There is no indication of financial statements, earnings data, or meeting materials. The content aligns with reporting of personal share transactions or holdings by company directors and executives. Therefore, this document fits the category of Director's Dealing (DIRS). The document length is 2934 characters, which is consistent with a detailed insider shareholding report rather than a brief announcement or a full financial report.

103年度財務比率
Fund Information / Factsheet Classification · 85% confidence The document contains a table of financial ratios and metrics for multiple fiscal years (101年度, 102年度, 103年度), including liquidity ratios, profitability ratios, turnover ratios, and cash flow ratios. The data is structured and quantitative, indicating a financial performance summary over multiple years. The document length is 952 characters, which is relatively short but contains substantive financial data rather than just an announcement or a link to a report. There is no indication that this is a full annual report or an interim report with full financial statements, but the presence of multiple years of financial ratios suggests it is a financial summary or factsheet. Given the concise nature and focus on key financial metrics, this aligns best with a Fund Information / Factsheet (FS) rather than a full Annual Report (10-K) or Interim Report (IR).

103年第4季海外子公司投資
Interim / Quarterly Report Classification · 85% confidence The document contains detailed financial data related to investments in overseas subsidiaries, including investment amounts, shareholding percentages, and recognized investment gains or losses. It references accounting standards and provides a tabular breakdown of investment balances and profits/losses for a specific period (103rd year, 4th quarter). The content is financial and analytical, not a brief announcement or a certification. The document length is 1553 characters, which is relatively short but contains substantive financial data. Given the detailed financial information and the period reference, this aligns with an Interim / Quarterly Report (IR) rather than a simple announcement or regulatory filing. There is no indication that this is an Annual Report or Earnings Release, and it is not a presentation or management change notice. Therefore, the best classification is Interim / Quarterly Report (IR). Q4 2014

103年第4季現金流量表
Interim / Quarterly Report Classification · 95% confidence The document contains a detailed consolidated cash flow statement for the fiscal year 103 (2014) fourth quarter, with extensive financial data including operating, investing, and financing activities. The presence of actual financial figures and comprehensive cash flow details indicates this is a financial report rather than a brief announcement or certification. The document length is 2781 characters, which is relatively short but contains substantive financial data. Given the quarterly period and detailed financial statements, this fits the definition of an Interim / Quarterly Report (IR). FY 2014

103年第4季綜合損益表
Interim / Quarterly Report Classification · 95% confidence The document contains a consolidated comprehensive income statement with detailed financial data for fiscal years 103 and 102 (Taiwanese calendar years), including revenue, costs, expenses, net income, and earnings per share. The presence of full 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 2364 characters, which is relatively short but contains actual financial data, not just a notice or link to a report. The content corresponds to a quarterly or interim financial report rather than a full annual report, as it specifies the 4th quarter of year 103 and includes quarterly financial figures. Therefore, the most appropriate classification is Interim / Quarterly Report (IR). FY 2014
2015-03-25 Chinese
103年第4季資產負債表
Annual Report Classification · 90% confidence The document contains a consolidated balance sheet with detailed financial data for the fiscal year ending December 31, 2014 (民國103年12月31日). It includes asset, liability, and equity figures, which are typical components of a financial report. The document length is 3386 characters, which is relatively short but contains substantive financial data rather than just an announcement or a certification. There is no indication that this is an announcement of a report or a certification letter. The presence of detailed financial statements for a full fiscal year suggests this is an Annual Report (10-K equivalent). Therefore, the document is classified as an Annual Report (10-K). Q4 2014
