Filing Released Lang Actions
104年10月背書保證與資金貸與
Regulatory Filings Classification · 90% confidence The document contains financial data related to loan balances, endorsements, and guarantees for the company and its subsidiaries, with specific monthly and cumulative amounts. It is a financial update but does not contain comprehensive financial statements or detailed analysis typical of an Interim/Quarterly Report (IR) or Annual Report (10-K). The document is relatively short (634 characters) and appears to be a regulatory disclosure of financial guarantees and loan balances rather than a full report. It does not fit into categories like Earnings Release, Management Reports, or Capital Updates. Given the nature of the data and the format, it aligns best with a Regulatory Filing (RNS), which is a fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

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 status of a subsidiary's fund lending exceeding limits and the improvement plan execution. It references regulatory guidelines from the Financial Supervisory Commission and provides details on the situation and corrective measures. The document is short (965 characters) and serves as a compliance disclosure rather than a full financial report or detailed management discussion. It does not contain financial statements or detailed analysis, nor is it a report publication announcement. This fits best under Regulatory Filings (RNS), which covers general regulatory announcements and compliance documents that do not fit other specific categories.

104年9月營業收入
Fund Information / Factsheet Classification · 85% confidence The document is a summary report of monthly and cumulative net operating revenue figures for a company named 台亞, with data for September of 民國104年 (2015). It includes percentage changes compared to the previous year and explanatory notes about accounting standards (IFRS) and reporting practices. The document is very short (777 characters) and contains financial data but is more of a brief revenue summary rather than a full financial report. It does not contain comprehensive financial statements or detailed analysis typical of an Interim/Quarterly Report (IR) or Annual Report (10-K). It also does not fit other categories like Earnings Release or Investor Presentation. Given the concise nature and focus on key financial figures, this best fits the Fund Information / Factsheet (FS) category, which is for brief summaries of key company facts and financials.

104年9月背書保證與資金貸與
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 months, including amounts related to subsidiaries and mainland China. The content is numerical and specific but very short (634 characters) and does not contain comprehensive financial statements or analysis. It appears to be a regulatory disclosure of financial guarantees and lending balances rather than a full report or announcement of a report. Given the short length and nature of the data, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

104年09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 share transactions and holdings rather than financial results, management changes, or other corporate events. There is no indication of a full financial report, earnings release, or meeting materials. The document is a report of personal share transactions and holdings by company directors and executives, which matches the definition of Director's Dealing (DIRS). The document length is sufficient and contains substantive data on insider holdings, not just an announcement or certification, so it is not Regulatory Filings (RNS) or Report Publication Announcement (RPA). Therefore, the appropriate classification is DIRS with high confidence.

104年09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 and pledged shares. It is a disclosure of insider shareholdings and related information. There is no indication of financial results, management discussion, voting results, or other report types. The content matches the description of a Director's Dealing or insider shareholding notification. Given the detailed insider shareholding data, this fits best with the category Major Shareholding Notification (MRQ), which covers notifications of changes or status of significant share ownership by insiders. The document is not a report or announcement of a report, nor a certification or legal proceeding. Therefore, the classification is MRQ with high confidence.
