108年10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, providing information about the absence of fund loans and endorsement guarantees for the current and previous months, with amounts stated as zero. It is a short, factual update without detailed financial statements or analysis. The document length is only 601 characters, indicating it is a concise regulatory disclosure rather than a full report. There is no indication of an annual or interim report, audit report, or other detailed filings. This type of document fits best under Regulatory Filings (RNS), which covers general regulatory announcements and compliance disclosures that do not fit other categories.

Director's Dealing Classification · 100% confidence The document consists of detailed tables listing shareholdings of company insiders, including directors, managers, and their related parties. It shows the number of shares held, increases, decreases, and other shareholding details for various insiders. This type of document is typical of a Director's Dealing or insider shareholding disclosure report, which tracks personal share transactions or holdings by company directors and executives. There is no indication of financial statements, earnings data, or meeting materials. The document is not an announcement of a report but a direct disclosure of insider shareholdings. Therefore, the most appropriate classification is Director's Dealing (DIRS).

Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by company insiders, including directors, managers, and related parties, showing their current holdings, pledged shares, and related percentages. It includes specific data on share ownership and internal relationships but does not contain financial statements, earnings data, or management discussion. The content is focused on insider shareholdings and their changes, which aligns with the category of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives. The document length is 2411 characters, which is relatively short but contains detailed insider shareholding data rather than just an announcement or a link to a report. Therefore, the best classification is DIRS.

108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 (榮創) reporting on the status of fund loans and endorsement guarantees for the current and previous month, including cumulative amounts and limits. It contains tabulated financial data but is very short (601 characters) and does not include comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure of specific financial information rather than a full report or announcement of a report. The content fits best under Regulatory Filings (RNS) as it is a compliance-type disclosure without the depth of an annual or interim report.

108年9月營業收入
Interim / Quarterly Report Classification · 90% confidence The document is a summarized revenue report from a listed company, showing monthly and cumulative net operating revenue figures with percentage changes compared to the previous year. It includes notes on accounting standards (IFRS) and reporting requirements. The document is short (778 characters) and primarily provides financial data for a specific month and year (September 2019). It does not contain a full annual or interim report, nor is it an announcement of a report publication. It is a financial data summary for a period shorter than a full fiscal year with substantive financial data and analysis. Therefore, it fits the definition of an Interim / Quarterly Report (IR).

Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings of company insiders, including directors, managers, and other key personnel. It shows the number of shares held, changes in holdings, and related information. The content is focused 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. This type of document aligns with the definition of Director's Dealing (DIRS), which reports personal share transactions by company directors and executives (insider trades). The document length is sufficient and contains substantive data on insider holdings, supporting this classification with high confidence.
