106年06月內部人持股未轉讓(事前)
Director's Dealing Classification · 100% confidence The document is a short tabular report showing a director's holding and planned transfer of shares, including reasons for not transferring. It lists the director's name, company code, and share quantities. This matches the definition of a Director's Dealing report, which details personal share transactions by company directors and executives. The document length is very short (408 characters), and it is not an announcement of a report but the actual data itself. Therefore, the correct classification is DIRS (Director's Dealing).

106年5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 presented for May 2017 (民國106年05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 contains no detailed financial statements or management discussion. It appears to be a regulatory disclosure of monthly revenue figures rather than a full financial report or earnings release. There is no indication of a conference call transcript, AGM materials, or management changes. Given the nature and length, this fits best as a Regulatory Filing (RNS) which covers general regulatory announcements and compliance disclosures that do not fit other categories.

106年5月背書保證與資金貸與
Regulatory Filings Classification · 90% confidence The document is a financial disclosure from a listed company (台亞) providing detailed figures on fund lending balances, endorsement guarantees, and related financial limits for a specific month (May of the 106th year in the ROC calendar, which corresponds to 2017). The content is numerical and relates to financial status updates rather than a full financial report or announcement of a report. The document length is short (642 characters), but it contains substantive financial data about fund lending and guarantees, which is typical of a regulatory financial disclosure. It does not fit the profile of an Annual Report, Interim Report, or Earnings Release, nor is it a simple announcement or certification. Given the nature of the data and the context, this is best classified as a Regulatory Filing (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.
