109年第4季資產負債表
Interim / Quarterly Report Classification · 95% 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 3640 characters, which is relatively short but contains substantive financial data rather than just an announcement or a link to a report. The presence of detailed financial statements indicates this is a financial report rather than a simple announcement or certification. Given the quarterly date and the detailed financial data, this aligns with an Interim / Quarterly Report (IR) rather than a full Annual Report (10-K) or other categories. Therefore, the document is best classified as an Interim / Quarterly Report (IR). FY 2020

109年度應收帳款周轉率
Regulatory Filings Classification · 95% confidence The document is very short (310 characters) and contains financial ratio data (accounts receivable turnover and average collection days) for two fiscal years (108 and 109). It includes a note explaining that changes are not significant enough to require further explanation. 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 related to financial ratios. Given the brevity and nature, it does not qualify as a full Annual Report, Interim Report, or Earnings Release. It is more consistent with a Regulatory Filing (RNS) as a miscellaneous financial disclosure that does not fit other categories.

109年第4季權益變動表
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial tables showing changes in equity for a company, including items such as common stock, capital surplus, legal surplus reserve, special surplus reserve, undistributed earnings, retained earnings, and treasury stock. The data is presented for two periods: the current period (year 109 in the Taiwanese calendar, corresponding to 2020) and the previous period (year 108, corresponding to 2019). The document is about consolidated equity changes, which is a typical component of a financial report. The document length is 4294 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 mere announcement or a certification letter. The content is consistent with a financial report, specifically an Interim / Quarterly Report (IR), as it provides detailed financial data for a period shorter than a full fiscal year and includes substantive financial tables. It is not an Annual Report (10-K) because the data is for a quarterly or interim period, and the document is not a simple announcement or a certification. Therefore, the best classification is Interim / Quarterly Report (IR). FY 2020

109年度存貨週轉率
Regulatory Filings Classification · 95% confidence The document is very short (304 characters) and contains a brief table with inventory turnover ratios and average sales days for two fiscal years (108 and 109). It includes a note explaining that the change in inventory turnover rate is not significant enough to require further explanation. There is no indication of a full financial report, management discussion, or detailed analysis. The content is a simple disclosure of a specific financial metric without comprehensive financial statements or narrative. Given the brevity and nature of the content, it does not qualify as an Annual Report, Interim Report, or Management Report. It is more consistent with a Regulatory Filing (RNS) as a general disclosure or compliance update that does not fit other categories.

109年度毛利率
Fund Information / Factsheet Classification · 90% confidence The document is very short (413 characters) and contains a simple table of annual revenue, cost, gross profit, and gross margin percentages for two years (108 and 109, likely referring to Taiwanese calendar years). It includes a note about gross margin changes and states no significant change requiring explanation. There is no detailed financial statement, no narrative management discussion, no regulatory certification, or announcement of a report publication. The content is a brief financial summary, likely a factsheet or summary data. Given the brevity and nature of the data, it fits best as a Fund Information / Factsheet (FS) rather than a full Annual Report or Interim Report. Therefore, the classification is FS with high confidence.

109年度營益分析
Interim / Quarterly Report Classification · 95% confidence The document contains financial data for multiple fiscal periods including quarterly (first quarter, half-year, third quarter) and full-year results. It includes detailed financial metrics such as operating revenue, gross margin, operating profit margin, pre-tax profit margin, and after-tax profit margin. The data is presented in a tabular format with specific fiscal years and periods, indicating substantive financial data and analysis. The document length is 1057 characters, which is relatively short but contains actual financial data rather than just an announcement or certification. The content aligns with an Interim / Quarterly Report (IR) as it covers quarterly and half-year financial performance with detailed metrics, not just a brief earnings release or announcement. Therefore, the most appropriate classification is Interim / Quarterly Report (IR). FY 2020
