107年第4季權益變動表
Interim / Quarterly Report Classification · 90% confidence The document contains detailed financial tables showing changes in equity for a company over two fiscal years (民國107年度 and 民國106年度), including items such as common stock, capital surplus, legal surplus reserve, special surplus reserve, undistributed earnings, retained earnings, and other equity components. The presence of comprehensive financial data and accounting items related to equity changes indicates this is a financial report rather than a brief announcement or certification. The document is about consolidated equity changes, which is typically part of an annual or interim financial report. Given the length (4995 characters) and the detailed financial data, it is consistent with an Interim / Quarterly Report (IR) or Annual Report (10-K). However, since the document focuses on equity changes and is for a specific period (likely quarterly or interim), and no explicit mention of a full annual report or audit report is present, the best fit is an Interim / Quarterly Report (IR). FY 2018

107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 (106 and 107, likely referring to Taiwanese calendar years). It includes a note about gross margin changes and states no significant change occurred. There is no detailed financial statement, no narrative management discussion, no regulatory certification, or announcement of voting or management changes. The document appears to be a brief financial summary or factsheet rather than a full report or announcement. Given the brevity and content, it fits best as a Fund Information / Factsheet (FS) which typically provides brief summaries of key financial data.

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 (106 and 107). It includes a statement about the lack of significant change requiring explanation. There is no indication of a full financial report, audit, or management discussion. The content is a brief factual disclosure likely related to regulatory requirements but does not constitute a full report or announcement of a meeting or vote.

The document is short (886 characters) and serves as a notice of the board's decisions and AGM arrangements rather than the full AGM materials or reports themselves. Therefore, it fits the category of AGM Information (AGM-R) as it relates to presentations and materials shared during the AGM or announcements about the AGM agenda and resolutions.
