Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings of company insiders, including directors, senior management, and their related parties. It shows the number of shares held, changes in holdings, and classifications of shares. This type of document is typical of a Director's Dealing report, which discloses personal share transactions by company directors and executives. There is no indication of financial statements, earnings data, or meeting materials. The document is not an announcement of a report but the actual disclosure of insider shareholdings and transactions. Therefore, the appropriate classification is Director's Dealing (DIRS).

107年12月營業收入
Regulatory Filings Classification · 95% confidence The document is a summary report of monthly and cumulative net operating revenue figures for a company named 台亞, with data for December 2018 (民國107年12月). It includes percentage changes compared to the previous year and explanatory notes about accounting standards and reporting practices. The document is very short (773 characters) and does not contain detailed financial statements or comprehensive analysis. It appears to be a brief financial summary or regulatory disclosure rather than a full financial report or earnings release. There is no indication of an earnings announcement, management discussion, or detailed financial data. Given the brevity and nature of the content, it fits best as a Regulatory Filing (RNS), which is a fallback category for miscellaneous filings that do not fit other specific categories.
