Director's Dealing Classification · 95% confidence The document contains 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 share ownership and transactions, which is characteristic of a Director's Dealing report. There is no indication of financial statements, earnings data, meeting materials, or other report types. The document length is substantial and contains actual data, not just an announcement or certification. Therefore, the document is best classified as a Director's Dealing report.

102年10月董事會成員及持股
Major Shareholding Notification Classification · 95% confidence The document contains detailed tables listing shareholdings of company insiders, including directors, supervisors, and executives, with specific numbers of shares held, pledged shares, and related percentages. It is a disclosure of insider shareholdings and pledges, typical of a Major Shareholding Notification or Director's Dealing report. However, since it lists holdings of multiple insiders and their pledges rather than individual insider transactions, it aligns more with a Major Shareholding Notification. The document is relatively short (3042 characters) and does not contain financial statements or earnings data, so it is not an Annual Report or Earnings Release. There is no indication of a meeting, voting results, or management changes. Therefore, the best fit is Major Shareholding Notification (MRQ).

公告本公司之子公司資金貸與超限訂定之改善計劃執行情形
Regulatory Filings Classification · 95% confidence The document is a regulatory announcement from a listed company (2340 台亞) regarding the execution status of an improvement plan related to the excess lending of funds by its subsidiary. It references compliance with financial supervisory authority regulations and provides details about the situation and corrective measures. The document is short (979 characters) and serves as a disclosure of a specific event or update rather than a full financial report or detailed management discussion. It does not contain financial statements or comprehensive analysis. Therefore, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory announcements that do not fit other specific categories.

102年9月背書保證與資金貸與
Regulatory Filings Classification · 95% confidence The document is a brief financial disclosure from a listed company (台亞) providing data on fund loans and endorsement guarantees for the current and previous months, including cumulative balances and limits. The content is short (634 characters) and consists mainly of tabular financial data related to guarantees and loans, without detailed financial statements or narrative analysis. It does not present a full financial report, nor does it announce a meeting or voting results. It is a regulatory disclosure of financial information but not a full report like an Annual Report or Interim Report. Given the nature and length, it fits best as a Regulatory Filing (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

There is no indication that this is an annual or interim report, nor is it an announcement or certification.
