106年第3季海外子公司投資
Interim / Quarterly Report Classification · 95% confidence The document contains detailed financial data related to investments in overseas subsidiaries, including investment amounts, shareholding percentages, and recognized investment gains or losses. It references accounting standards and provides a tabular breakdown of investment balances and profits for a specific period (106年3季, which corresponds to the third quarter of a fiscal year). The document length is short (1378 characters) and it contains substantive financial data rather than just an announcement or certification. This aligns with an Interim / Quarterly Report (IR) as it provides comprehensive financial information for a period shorter than a full fiscal year, including actual financial figures and analysis. It is not a brief announcement or a certification, nor is it a full annual report or earnings release summary. Therefore, the best classification is Interim / Quarterly Report (IR). 9M 2017

106年10月營業收入
Interim / Quarterly Report Classification · 95% confidence The document is a summarized revenue report for a company named 台亞, showing monthly and cumulative net operating revenue figures with comparisons to the previous year. It includes notes on accounting standards (IFRS) and reporting practices. The document length is short (772 characters) and it primarily provides financial data for a specific month and year (民國106年10月, which corresponds to October 2017). This matches the characteristics of an Interim / Quarterly Report (IR), as it contains substantive financial data for a period shorter than a full fiscal year. It is not an announcement or a certification but actual financial figures and analysis. Therefore, the correct classification is IR with high confidence. Q3 2017

106年10月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a financial disclosure from a listed company (台亞) providing detailed figures on fund loans and endorsement guarantees for a specific month (October of the 106th year of the Republic of China calendar, which corresponds to 2017). The content includes numerical data on loan balances, guarantee amounts, and limits, but it is very short (640 characters) and does not contain comprehensive financial statements or analysis. It appears to be a regulatory disclosure of financial information related to guarantees and loans rather than a full financial report or announcement of a meeting or vote. Given the nature and length, it fits best as a Regulatory Filing (RNS), which is a fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

106年第3季大陸投資
Regulatory Filings Classification · 95% confidence The document is a detailed tabular disclosure of investment amounts, investment methods, and related financial figures concerning investments in mainland China by a Taiwanese listed company. It includes specific financial data such as capital amounts, investment income, and investment limits approved by the Ministry of Economic Affairs. The document is relatively short (1476 characters) and focuses on investment details rather than a full financial report or earnings announcement. It does not present comprehensive financial statements or management discussion but rather regulatory-required investment disclosures. This type of document aligns with regulatory filings that provide compliance and investment information but do not constitute full reports like Annual or Interim Reports. Therefore, the best classification is Regulatory Filings (RNS).

106年10月內部人持股異動(事後)
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. The content is focused on insider share transactions and holdings rather than financial results, governance policies, or meeting materials. There is no indication of a report or announcement of a report, nor is there any financial statement or management discussion. The document is a report of personal share transactions and holdings by company directors and executives, fitting the definition of Director's Dealing (DIRS). The document length is sufficient and contains substantive data on insider shareholdings, confirming it is not a mere announcement or certification.
