107年2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 information on fund loans, endorsements, and guarantees for a specific month (February of the 107th year in the ROC calendar, which corresponds to 2018). The content includes numerical data on loan balances, guarantee amounts, and limits, but it is very brief (641 characters) and does not contain comprehensive financial statements or analysis. It appears to be a regulatory disclosure or compliance update rather than a full financial report or announcement of a meeting or vote. 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.

107年1月背書保證與資金貸與
Capital/Financing Update Classification · 90% confidence The document is a financial disclosure from a listed company (台亞) providing detailed information on fund loans, endorsements, and guarantees for a specific month (January of the 107th year in the ROC calendar, which corresponds to 2018). The content includes numerical data on loan balances, guarantee amounts, and related financial limits. The document length is short (647 characters) and it primarily presents financial data related to capital lending and guarantees rather than a full financial report or announcement. It does not appear to be an annual or interim report, earnings release, or management discussion. It is a regulatory disclosure of financial information related to capital and guarantees, which fits best under the category of Capital/Financing Update (CAP).

107年1月營業收入
Interim / Quarterly Report Classification · 85% confidence The document is a summarized revenue report for a company named 台亞 for the month of January in 民國107年 (2018). It contains numerical financial data such as net operating revenue for the current month and year-to-date, compared to the previous year, with percentage changes. The document is short (774 characters) and appears to be a periodic financial 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 nature of the data and the length, it best fits the category of Interim / Quarterly Report (IR), as it provides substantive financial data for a period shorter than a full fiscal year. Q1 2018

107年01月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document contains detailed tables listing shareholdings of company insiders, including directors, managers, and their related parties. It shows changes in shareholdings, types of shares held, and other related insider information. There is no indication of financial statements, earnings data, or meeting results. The content is focused on insider share transactions and holdings. This matches 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 the content is consistent with insider shareholding disclosures rather than a general regulatory filing or announcement.

The content is focused on capital structure information and does not contain financial statements or detailed analysis. The document length is short (810 characters), and it appears to be a regulatory announcement about capital changes rather than a full report.
