Filing Released Lang Actions
114年度存貨週轉率
Regulatory Filings Classification · 95% confidence The document is very short (304 characters) and contains inventory turnover ratios and average sales days for two fiscal years. It includes a note explaining that the change in inventory turnover rate is not significant enough to require explanation. There is no indication of a full financial report, management discussion, or regulatory filing. The content is a brief factual data snippet, likely part of a larger report or disclosure but by itself does not constitute a full report or announcement. Given the brevity and nature of the data, it does not fit into detailed report categories like Annual Report (10-K), Interim Report (IR), or Management Reports (MDA). It is also not an announcement or notice. The best fit is Regulatory Filings (RNS) as a general category for miscellaneous disclosures that do not fit other categories.

Regulatory Filings Classification · 95% confidence The document is very short (412 characters) and contains a brief financial summary table with annual revenue, cost, gross profit, and gross margin percentages for two years. It includes a note about gross margin changes but no detailed financial statements or comprehensive analysis. There is no indication that this is a full annual or interim report, nor is it a presentation or announcement of voting results. The document appears to be a brief financial data disclosure, likely a regulatory filing or a summary update. Given the brevity and nature, it fits best under Regulatory Filings (RNS) as a general financial disclosure without detailed reporting or analysis.

AGM Information Classification · 95% confidence The document is a formal announcement from a listed company (2340 台亞) regarding the resolutions of its board of directors related to the upcoming Annual General Meeting (AGM) scheduled for 115/06/25. It details the agenda items for the AGM, including reports, approvals, elections, and other matters. The document is short (838 characters) and serves as a notification of the board's decisions and AGM arrangements rather than the full AGM materials or the annual report itself.

公告本公司114年度財務報告董事會預計 召開日期為115年02月26日
Regulatory Filings Classification · 95% confidence The document is a short announcement from a company (2340 台亞) stating the planned date for the board meeting to discuss the 114th fiscal year financial report. It includes the board meeting convocation date and the expected date of the meeting, but does not contain the financial report itself or detailed financial data. The document is only notifying about the upcoming board meeting and the intention to present the annual financial report, not the report itself. The length is very short (547 characters), and it fits the pattern of a Regulatory Filing (RNS) as a general announcement about corporate actions without substantive financial content.

It is a regulatory disclosure about an asset acquisition, not a financial report or earnings release. The document length is short (1777 characters) and it does not contain financial statements or detailed financial analysis. It fits the category of a general regulatory announcement about a corporate transaction, which aligns with Regulatory Filings (RNS).

115年1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 information on fund loans and endorsement guarantees for the current and previous month, including limits and cumulative balances. It is short (633 characters) and contains tabular financial data but does not present a full financial report or detailed analysis. It appears to be a regulatory disclosure or compliance update rather than a full report like an Annual Report or Interim Report. There is no indication of a meeting, voting results, management changes, or legal proceedings. The content fits best as a Regulatory Filing (RNS) because it is a general regulatory announcement of financial data without the depth of a full report.
