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 rather than financial results, management changes, or meeting materials. There is no indication of financial statements, earnings data, or meeting presentations. The document is a regulatory disclosure of insider shareholdings, which aligns with the category of Director's Dealing (DIRS), as it reports personal share transactions by company directors and executives. The document length is sufficient and contains substantive data on insider holdings and changes, not just an announcement or certification. Therefore, the best classification is DIRS with high confidence.

Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders and related parties of the company 台亞半導體股份有限公司, including directors, supervisors, and senior management. It lists the number of shares held, pledged shares, and related percentages.

Given the nature of the content as a brief financial summary, it best fits the category of Fund Information / Factsheet (FS), which is defined as a brief summary of key company facts and financials.
