113年度財務比率
Fund Information / Factsheet Classification · 90% confidence The document contains a financial data table showing key financial ratios and metrics for three consecutive fiscal years (111, 112, 113年度). The data includes financial structure, debt ratios, liquidity ratios, operational efficiency, profitability, and cash flow metrics. The document is relatively short (1008 characters) and appears to be a summary or analysis of recent three-year financial data provided by the company. There is no indication that this is a full annual report or interim report with detailed financial statements. It also does not appear to be an announcement or notice but rather a brief financial factsheet or summary. Given the concise nature and focus on key financial metrics over multiple years, the best fitting category is Fund Information / Factsheet (FS).

113年度應收帳款周轉率
Fund Information / Factsheet Classification · 90% confidence The document is very short (309 characters) and contains financial ratio data related to accounts receivable turnover and average collection days for two fiscal years. It includes a note explaining that changes less than 20% do not require further explanation. There is no indication of a full financial report, management discussion, or regulatory filing. The content resembles a brief financial fact sheet or summary of key financial metrics rather than a detailed report or announcement. Given the brevity and nature of the data, the best fitting category is Fund Information / Factsheet (FS), which covers brief summaries of key company financials and facts.

113年度存貨週轉率
Regulatory Filings Classification · 95% confidence The document is very short (304 characters) and contains inventory turnover ratios and average sales days for two fiscal years (112 and 113). 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, audit, or management discussion. The content is a brief factual data disclosure likely related to regulatory compliance or a routine operational metric update. Given the brevity and nature of the content, 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 general disclosure of operational metrics without substantive financial statements or analysis.

113年度毛利率
Fund Information / Factsheet Classification · 85% confidence The document contains annual financial data including net operating revenue, operating costs, gross profit, and gross profit margin for two consecutive years (112年度 and 113年度). It also includes an explanation for a significant change in gross profit margin. The document is very short (424 characters) and appears to be a brief financial summary or excerpt rather than a full annual report or detailed financial statement. There is no indication that this is an announcement of a report publication or a certification. Given the brief nature and the financial data presented, this fits best as a Fund Information / Factsheet (FS) or a brief financial summary. However, since it is from a company and not explicitly a fund, and it is a short summary of key financials, the best fit is Fund Information / Factsheet (FS).

113年度營益分析
Interim / Quarterly Report Classification · 95% confidence The document contains detailed quarterly and annual financial performance data including revenue, gross margin, operating profit margin, pre-tax profit margin, and after-tax profit margin for multiple fiscal years. The data covers multiple periods within each fiscal year (first quarter, half-year, third quarter, full year). This level of detailed financial data and period coverage is characteristic of an Interim / Quarterly Report rather than a brief summary or announcement. The document length is short (1066 characters), but it contains substantive financial data, not just a notice or certification. Therefore, it is classified as an Interim / Quarterly Report (IR).

113年第4季權益變動表
Interim / Quarterly Report Classification · 90% confidence The document contains detailed tables of consolidated equity changes for a company, including line items such as common stock, capital surplus, legal surplus reserve, undistributed earnings, retained earnings, foreign currency translation adjustments, and other comprehensive income items. The data is presented for the current period and the same period last year, with amounts in thousands of New Taiwan Dollars. This type of detailed equity statement is typically part of a comprehensive financial report rather than a brief announcement or a certification. The document length is 4585 characters, which is relatively short but contains substantive financial data. There is no indication that this is an announcement of a report or a certification letter. The content aligns with financial statements found in an Interim / Quarterly Report (IR), as it provides detailed financial data for a period shorter than a full fiscal year (the document mentions the 4th quarter of 2024). Therefore, the document is best classified as an Interim / Quarterly Report (IR).
