Filing Released Lang Actions
係因本公司有價證券於集中交易市場達公布注意交易資訊標準， 故公布相關財務業務等重大訊息，以利投資人區別瞭解。
Regulatory Filings Classification · 95% confidence The document is a short announcement from a listed company (2340 台亞) disclosing recent financial information due to reaching a threshold for disclosure under Taiwan Stock Exchange regulations. It provides summarized financial data for recent periods but does not contain a full financial report or detailed analysis. The document length is only 1361 characters, which is quite short and consistent with a regulatory announcement rather than a full report. It explicitly states it is disclosing "重大訊息" (material information) as required by the exchange, referencing compliance with specific exchange rules. There is no indication this is a full Annual Report, Interim Report, or Earnings Release. It is not a certification or officer attestation. The document is best classified as a Regulatory Filing (RNS) because it is a general regulatory announcement of material financial information without the depth or format of a formal financial report.

公告本公司107年股東常會決議事項
Declaration of Voting Results & Voting Rights Announcements Classification · 95% confidence The document is a formal announcement from a company (2340 台亞) regarding the resolutions passed at its Annual General Meeting (AGM) held on 107/06/20 (Taiwan calendar year, equivalent to 2018). It details key decisions such as dividend distribution, approval of financial statements and business reports for the fiscal year 106 (2017), and other AGM-related matters. The content is focused on the outcomes of the shareholder meeting rather than the full report itself. The document length is short (633 characters), and it explicitly states the resolutions passed at the AGM, which aligns with the category of Declaration of Voting Results & Voting Rights Announcements (DVA). It is not a full Annual Report or financial report, nor is it a mere announcement of a report publication. Therefore, the correct classification is DVA with high confidence.

There is no indication of financial statements, earnings data, or meeting materials. The document is not an announcement of a report but contains substantive data on insider shareholdings and transactions. Therefore, the appropriate classification is Director's Dealing (DIRS).

The document length is short (644 characters), and it is not an announcement of a report publication but a direct disclosure. Therefore, it fits best under Regulatory Filings (RNS).
