Regulatory Filings Classification · 95% confidence The document is a tabular financial disclosure showing investment details in overseas subsidiaries, including shareholding percentages, original investment amounts, investment balances, and recognized investment gains or losses for the current period and prior year-end.

There is no indication of a full annual or interim report, audit report, or earnings release. It does not contain management commentary or detailed financial statements.

Director's Dealing Classification · 100% confidence The document consists of detailed tables listing shareholdings of company insiders, including directors, managers, 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).

108年6月營業收入
Regulatory Filings Classification · 90% confidence The document is a summary report of monthly and cumulative net operating revenue figures for a company named 台亞, with data for June 2019 (民國108年06月). It includes percentage changes compared to the previous year and explanatory notes about accounting standards and reporting practices. The document is short (774 characters) and primarily presents financial summary data without detailed financial statements or management discussion. It does not appear to be a full annual or interim report, nor an earnings release or investor presentation. It is a regulatory disclosure of financial summary data, typical of a regulatory filing or a brief financial update. Given the short length and nature of the content, it fits best under Regulatory Filings (RNS) as a general regulatory announcement of financial data without the depth of a full report.
