107年4月營業收入
Interim / Quarterly Report Classification · 85% confidence The document is a summary report of monthly and cumulative operating revenue figures for a company named 台亞, presented in a tabular format with explanations about accounting standards and reporting practices. It contains financial data for a specific month (April 2018) and compares it to the previous year. The document is short (776 characters) and appears to be a periodic financial summary rather than a full comprehensive report. It does not contain detailed financial statements or management discussion, nor is it an announcement or certification. Given the presence of actual financial data for a period shorter than a full fiscal year and the nature of the content, this fits the definition of an Interim / Quarterly Report (IR). Q1 2018

107年4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 detailed data on fund loans, endorsements, and guarantees for a specific month (April 2018, 民國107年04月). The content includes numerical financial data but is very short (645 characters) and focuses on specific financial metrics related to loans and guarantees rather than comprehensive financial statements or management discussion. It does not present a full annual or interim report, nor is it an announcement of a meeting or voting results. The document appears to be a regulatory disclosure of financial information related to credit and guarantees, which fits best under Regulatory Filings (RNS) as it does not meet the criteria for other more specific categories like Annual Report, Interim Report, or Capital/Financing Update. The short length and nature of the data support this classification with high confidence.

107年第1季海外子公司投資
Regulatory Filings Classification · 90% confidence The document is a tabular financial disclosure showing investment amounts, shareholding percentages, and recognized investment gains or losses for various overseas subsidiaries for the first quarter of the 107th year (likely referring to a fiscal quarter). The content is numerical and financial but very brief (1372 characters) and does not contain comprehensive financial statements or detailed analysis. It appears to be a regulatory disclosure of investment holdings and results rather than a full interim or annual report. Given the short length and nature of the data, it is not a full Interim/Quarterly Report (IR) or Annual Report (10-K). It is more consistent with a Regulatory Filing (RNS) as a general regulatory announcement or financial disclosure that does not fit other specific categories.

107年第1季大陸投資
Regulatory Filings Classification · 95% confidence The document is a detailed tabular disclosure of investment amounts and related financial data concerning investments in mainland China by a Taiwanese listed company. It includes specific financial figures, investment methods, and regulatory limits. The content is regulatory in nature, providing compliance information about cross-border investments, but it does not constitute a full financial report, earnings release, or management discussion. The document length is short (1478 characters), and it is a structured disclosure likely filed to meet regulatory requirements. It does not announce or attach a report but provides direct data. This fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

107年03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, managers, and their related parties. It shows the number of shares held, changes in holdings, and classifications of shares for various insiders. This type of document is typically a disclosure of insider share transactions or holdings by directors and executives. There is no indication of financial statements, earnings data, or meeting materials. The content aligns with reporting personal share transactions or holdings by company directors and executives, which fits the definition of Director's Dealing (DIRS). The document length is sufficient and contains substantive data, not just an announcement or certification. Therefore, the appropriate classification is DIRS.

107年03月董事會成員及持股
Director's Dealing Classification · 95% confidence The document is a detailed tabulation of shareholdings by insiders and related parties, including directors and senior management, showing their current and initial shareholdings, pledged shares, and related percentages. It is a typical insider shareholding disclosure report. There is no indication of financial statements, earnings data, meeting materials, or voting results. The document is not a report publication announcement or certification but a direct disclosure of insider shareholdings. This matches the definition of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives (insider trades). The document length is 3025 characters, consistent with a concise insider shareholding report rather than a full financial report or announcement. Therefore, the correct classification is DIRS with high confidence.
