102年03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 insiders, including directors, supervisors, general managers, and other key personnel, 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 results. The document is a report on insider shareholdings, which corresponds to notifications of personal share transactions or holdings by company directors and executives. Therefore, the document fits the category of Director's Dealing (DIRS). The document length is sufficient and contains substantive data, not just an announcement or certification, supporting this classification.

Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings and stock pledges by company insiders, including directors, supervisors, and senior management. It lists the number of shares held, pledged shares, and related percentages. The document does not contain financial statements, earnings data, or management discussion. It is a disclosure of insider shareholdings and pledges, which aligns with reporting on insider transactions or holdings. This type of document fits best under Director's Dealing (DIRS), which covers reports of personal share transactions or holdings by company directors and executives. The document length is about 3,000 characters, which is consistent with a detailed insider shareholding report rather than a brief announcement or a full financial report. Therefore, the classification is DIRS with high confidence.

Regulatory Filings Classification · 95% confidence The document is very short (602 characters) and contains tabular financial data related to loan balances, endorsements, and guarantees for the company and its subsidiaries. It does not contain comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure of financial guarantees and loan balances rather than a full financial report. There is no indication of it being an annual or interim report, earnings release, or other detailed report. 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.
