104年度毛利率
Regulatory Filings Classification · 95% confidence The document is very short (413 characters) and contains a simple financial summary table with annual revenue, cost, gross profit, and gross margin percentages for two years (103 and 104). It includes a note about gross margin changes but no detailed financial statements or comprehensive analysis. There is no indication that this is a full annual or interim report, nor is it a presentation or announcement of voting results. The document appears to be a brief financial data disclosure, likely a regulatory filing or a summary report. Given the brevity and nature, it fits best under Regulatory Filings (RNS) as a general financial disclosure without detailed reporting or analysis.

104年第4季權益變動表
Interim / Quarterly Report Classification · 85% 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, special surplus reserve, undistributed earnings, retained earnings, and other equity items. The data is presented for the current period and the previous year, with amounts in thousands of New Taiwan Dollars. The document is a financial statement showing changes in equity, which is typically part of a comprehensive financial report. However, the document length is 4366 characters, which is relatively short and does not contain a full set of financial statements or extensive analysis. It appears to be a specific financial statement rather than a full annual or interim report. Given the nature of the data (equity changes) and the absence of other financial statements or narrative, this document best fits the category of an Interim / Quarterly Report (IR) as it contains substantive financial data for a period shorter than a full fiscal year. The document is not an announcement or a certification, so it is not RPA or RNS. Therefore, the classification is IR with high confidence. FY 2015

104年度應收帳款周轉率
Regulatory Filings Classification · 90% confidence The document is very short (310 characters) and contains financial ratio data related to accounts receivable turnover and average collection days for two fiscal years (103 and 104). It includes a note explaining that changes less than 20% do not require further explanation. There is no indication of a full financial report, audit, or management discussion. The content is a brief financial metric disclosure, likely part of a regulatory or compliance filing rather than a full report. Given the brevity and nature, it fits best as a Regulatory Filing (RNS) rather than a full Annual Report or Interim Report.

104年度營益分析
Interim / Quarterly Report Classification · 95% confidence The document contains tabulated financial data for multiple fiscal periods including quarterly and annual figures such as operating revenue, gross margin, operating profit margin, pre-tax profit margin, and after-tax profit margin. The data spans multiple years and includes detailed financial metrics, indicating it is a comprehensive financial report for periods shorter than a full fiscal year (quarters and half-year). The document length is short (1044 characters), but it contains substantive financial data rather than just an announcement or certification. Therefore, it fits the definition of an Interim / Quarterly Report (IR). FY 2015

104年度財務比率
Fund Information / Factsheet Classification · 95% confidence The document contains a financial data analysis for the company 台亞 over three fiscal years (102年度, 103年度, 104年度), showing various financial ratios and performance metrics such as debt ratio, liquidity ratios, turnover rates, profitability ratios, and cash flow ratios. The content is a summary of financial data over multiple years but does not include detailed financial statements or comprehensive narrative analysis typical of full annual or interim reports. The document length is only 1004 characters, which is quite short and more consistent with a brief financial summary or factsheet rather than a full report. There is no indication that this is an announcement or publication notice of a report, nor is it a transcript, management discussion, or regulatory filing. Given the concise presentation of key financial metrics over multiple years, this document best fits the definition of a Fund Information / Factsheet (FS), which is a brief summary of key company facts and financials.

104年第4季海外子公司投資
Financial Supplement Data Classification · 85% confidence The document is a financial table showing investment details in overseas subsidiaries, including shareholding percentages, original investment amounts, investment balances, and recognized investment gains or losses for a specific period (104th year, 4th quarter). The content is detailed financial data related to equity method investments, which is typical of a financial report or supplementary financial data. However, the document length is only 1557 characters, which is quite short and does not contain a full financial report or comprehensive analysis. It appears to be a detailed financial data table rather than a full report. Given the short length and the nature of the data, this is best classified as Financial Supplement Data (XLSX) or a similar category. Since the document is not an Excel file but a tabular financial data excerpt, the closest fitting category is Financial Supplement Data (XLSX).
