112年5月營業收入
Regulatory Filings Classification · 95% confidence The document is a revenue summary report from a listed company (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 is very short (777 characters) and primarily provides summarized financial data without detailed financial statements or management discussion. It does not appear to be a full financial report like an Annual Report (10-K) or Interim Report (IR). It also does not fit categories like Earnings Release or Investor Presentation since it lacks highlights or strategic content. Given the nature and length, it is best classified as a Regulatory Filing (RNS), which is a fallback category for miscellaneous regulatory announcements and summary data disclosures that do not fit other specific categories.

112年04月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings of company insiders, including directors, supervisors, and senior management, with specific numbers of shares held, changes in holdings, and related notes. The content focuses on insider shareholding disclosures, showing individual and related party holdings, increases, decreases, and trust shares. There is no indication of financial statements, earnings data, meeting materials, or legal proceedings. The document is a regulatory disclosure of insider share transactions or holdings. According to the filing definitions, this matches the category 'Director's Dealing' (DIRS), which covers reports of personal share transactions by company directors and executives (insider trades). The document length is sufficient and contains substantive data on insider holdings, not just an announcement or certification. Therefore, the correct classification is DIRS with high confidence.

Director's Dealing Classification · 95% confidence The document is a detailed tabular disclosure of shareholdings by insiders and related parties of the company 台亞半導體股份有限公司.

There is no indication of a meeting, voting results, financial performance data, or management discussion.

Given the nature of the data (insider holdings and pledges), this fits the category of Director's Dealing (DIRS).

Regulatory Filings Classification · 95% confidence The document is a financial disclosure from a listed company (台亞) providing details on fund lending balances and endorsement guarantees for the current and previous month, including maximum limits. It contains specific financial figures but is very short (633 characters) and appears to be a regulatory disclosure of financial status rather than a full financial report or announcement. There is no indication of it being an annual or interim report, earnings release, or other detailed report. It fits best as a Regulatory Filing (RNS) because it is a general regulatory announcement of financial data without the depth or context of a full report.
