114年第4季大陸投資
Regulatory Filings Classification · 95% confidence The document is a tabular disclosure of investment information related to investments in mainland China by a Taiwanese listed company. It includes details such as invested capital, investment methods, cumulative investment amounts, and regulatory approval limits. The document is short (1276 characters) and primarily provides regulatory-required investment disclosures rather than financial statements or management commentary. There is no indication of it being an annual or quarterly report, audit report, earnings release, or any other detailed financial or management report. It is a regulatory disclosure related to investment activities, which fits best under the category of Regulatory Filings (RNS) as a general compliance announcement that does not fit other specific categories.

114年度應收帳款周轉率
Fund Information / Factsheet Classification · 90% confidence The document is very short (281 characters) and contains financial ratio data related to accounts receivable turnover and average collection days for two fiscal years. There is no indication of a full financial report, management discussion, or regulatory announcement. The content resembles a brief financial fact summary or key financial metrics. Given the brevity and nature of the data, it fits best as a Fund Information / Factsheet (FS) which typically provides concise financial highlights and key metrics.

114年度存貨週轉率
Regulatory Filings Classification · 95% confidence The document is very short (279 characters) and contains a brief table with inventory turnover ratios and average sales days for two years. There is no indication of a full financial report, management discussion, or detailed analysis. It appears to be a small data disclosure or a regulatory snippet rather than a comprehensive report. Given the brevity and nature of the content, it does not fit into detailed report categories like Annual Report (10-K) or Interim Report (IR). It is more consistent with a Regulatory Filing (RNS) as a general disclosure or compliance document without substantive financial statements or narrative.

114年度毛利率
Fund Information / Factsheet Classification · 85% confidence The document is very short (382 characters) and contains a brief financial summary table with annual revenue, cost, gross profit, and gross margin percentages for two years. There is no detailed financial statement, management discussion, or comprehensive report content. It appears to be a simple financial data disclosure or summary rather than a full report. Given the brevity and nature of the content, it does not qualify as an Annual Report (10-K), Interim Report (IR), or Earnings Release (ER). It also does not fit other specific categories like Audit Report or Management Report. The document resembles a brief financial summary or factsheet. Therefore, the best fitting category is Fund Information / Factsheet (FS).

114年度營益分析
Interim / Quarterly Report Classification · 90% confidence The document contains financial data segmented by fiscal periods such as first quarter, half-year, third quarter, and full year, with detailed metrics like revenue, gross margin, operating profit margin, pre-tax profit margin, and after-tax profit margin. The data is presented in a tabular format and covers multiple years. The document length is only 1050 characters, which is quite short for a full comprehensive report but contains substantive financial data for quarterly and annual periods. Given the presence of quarterly and annual financial metrics, this aligns best with an Interim / Quarterly Report (IR) classification, as it provides actual financial data and analysis for periods shorter than a full fiscal year. It is not a mere announcement or certification, and it is not a full annual report (10-K) due to the inclusion of quarterly data and the relatively short length. Therefore, the most appropriate classification is IR with high confidence.

114年第4季權益變動表
Interim / Quarterly Report Classification · 85% confidence The document is a consolidated statement of changes in equity for a company, showing detailed financial data such as share capital, capital surplus, retained earnings, and other equity components for the current and previous fiscal periods. It includes actual financial figures and accounting items, indicating it is a substantive financial report rather than a brief announcement or certification. The document length is 3904 characters, which is relatively short but contains detailed financial tables and data. This type of financial statement is typically part of an Interim or Quarterly Report (IR) or Annual Report (10-K). However, since the document covers a specific period within a fiscal year (indicated by the mention of the 4th quarter of 2025 and comparison with the previous year), and it contains detailed financial data but not a full annual report, it fits best as an Interim / Quarterly Report (IR).
