110年第4季權益變動表
Interim / Quarterly Report Classification · 95% 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, foreign currency translation adjustments, unrealized gains/losses on financial assets, treasury stock, and total equity attributable to the parent company and non-controlling interests. 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 4713 characters, which is sufficient to contain substantive financial data. There is no indication that this is merely an announcement or a certification. The content aligns with a financial report that includes detailed financial statements and analysis for a fiscal period. Given the nature of the data and the presentation, this document is best classified as an Interim / Quarterly Report (IR). FY 2021

110年度存貨週轉率
Regulatory Filings Classification · 95% confidence The document is very short (304 characters) and contains only a brief table of inventory turnover ratios and average sales days for two fiscal years (109 and 110). It includes a note explaining that the change in inventory turnover rate is not significant enough to require further explanation. There is no detailed financial data, no narrative management discussion, no regulatory or audit information, and no indication of a full report. The content is a simple factual disclosure likely related to regulatory requirements for inventory turnover metrics. Given the brevity and nature of the content, it does not qualify as a full Annual Report, Interim Report, or any detailed financial filing. It is best classified as a Regulatory Filing (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other categories.

It includes a note about the update date and a statement about the gross margin change analysis. There is no detailed financial statement, management discussion, or comprehensive report content. The document appears to be a brief financial fact summary or a simple data disclosure rather than a full report or announcement.

110年度應收帳款周轉率
Regulatory Filings Classification · 95% confidence The document is very short (309 characters) and contains financial ratio data (accounts receivable turnover and average collection days) for two fiscal years (109 and 110). It includes a note about the significance of changes in the turnover ratio. 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 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 financial information without substantive financial statements or analysis.

It details the old and new accounting firms and auditors, reasons for the change, and related procedural information. There is no financial data, report content, or detailed financial analysis present. The document is an announcement about a management decision related to audit services, not the audit report itself or an annual/interim report. This fits best under Regulatory Filings (RNS) as it is a regulatory announcement about auditor changes without substantive financial statements or audit results.
