109年第4季綜合損益表
Annual Report Classification · 95% confidence The document contains a consolidated comprehensive income statement with detailed financial data for the fiscal year 109 (2020) and the previous year 108 (2019). It includes revenue, costs, expenses, net income, and earnings per share figures. The presence of detailed financial statements and analysis for a full fiscal year indicates this is a full annual financial report. The document length is 2865 characters, which is relatively short but contains substantive financial data, not just an announcement or certification. The content matches the characteristics of an Annual Report (10-K) or equivalent annual financial report.

109年第4季資產負債表
Annual Report Classification · 85% confidence The document contains a consolidated balance sheet with detailed financial data for the fiscal year ending December 31, 2020 (民國109年12月31日). It includes asset, liability, and equity figures, which are typical components of a financial report. The document length is 2913 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 a partial or quarterly report; the data is for the full year 2020. The document is not a simple announcement or a certification letter, nor is it a presentation or a voting result. Therefore, this document is best classified as an Annual Report (10-K) or equivalent full-year financial report. Given the data is for the full fiscal year and includes comprehensive financial statements, the classification is 10-K with high confidence. FY 2020

Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial data for multiple fiscal periods including quarterly (first quarter, half-year, third quarter) and full-year results. It includes metrics such as operating revenue, gross margin, operating profit margin, pre-tax profit margin, and after-tax profit margin. The presence of actual financial figures and analysis for partial fiscal periods (quarters and half-year) indicates this is a comprehensive interim or quarterly financial report rather than a brief announcement or summary. The document length is 1064 characters, which is relatively short but contains substantive financial data, so it is not merely a report publication announcement or certification. Therefore, the document best fits the category of an Interim / Quarterly Report (IR). FY 2020

109年度毛利率
Fund Information / Factsheet Classification · 90% confidence The document is very short (430 characters) and contains a brief financial summary with revenue, cost, gross profit, and gross margin percentages for two fiscal years (108 and 109). It also includes a short explanation for a significant change in gross margin. There is no indication that this is a full annual or interim report, nor is it a detailed earnings release or management discussion. The document appears to be a brief financial fact summary or a snippet of financial data rather than a comprehensive report or announcement. Given the brevity and nature of the content, it best fits the category of Fund Information / Factsheet (FS), which is defined as a brief (1-2 page) summary of key company facts and financials.

It includes a note explaining that changes less than 20% are not analyzed. There is no indication of a full financial report, management discussion, or detailed financial statements. The content resembles a brief financial metric disclosure or a regulatory filing update rather than a full report or announcement. Given the brevity and nature of the content, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous filings that do not fit other specific categories.

Regulatory Filings Classification · 95% confidence The document is very short (292 characters) and contains a brief table with inventory turnover rates and average sales days for two fiscal years (108 and 109). It includes a note about significant changes in inventory turnover rates but does not provide comprehensive financial statements or detailed analysis. There is no indication that this is a full annual or interim report, nor is it an announcement of a meeting, voting results, or management changes. The content is a brief factual disclosure likely related to regulatory reporting requirements but does not fit into detailed report categories. Given the brevity and nature of the content, it best fits the Regulatory Filings (RNS) category as a general regulatory announcement or disclosure.
