109年02月董事會成員及持股
Director's Dealing Classification · 95% confidence The document contains detailed tabular data about shareholdings of company insiders, including directors, independent directors, and senior management, with specific numbers of shares held, pledged shares, and related percentages. It is a disclosure of insider shareholdings and changes, typical of a Director's Dealing or insider shareholding notification. The document is not a report or announcement of a meeting, financial results, or legal matters. It does not contain financial statements or management discussion. The presence of insider names, titles, and shareholding details aligns with the category of Director's Dealing filings, which report personal share transactions by company directors and executives. The document length is about 3,087 characters, which is sufficient for such a detailed insider shareholding report. Therefore, the most appropriate classification is Director's Dealing (DIRS).

109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 company named 台亞, providing data on fund loans, endorsements, and guarantees for the current and previous months, including limits and cumulative amounts. The content is a regulatory financial update related to the company's financial guarantees and fund lending status. The document length is short (628 characters) and it does not contain comprehensive financial statements or detailed analysis. It appears to be a regulatory announcement or compliance disclosure rather than a full financial report or earnings release. There is no indication of it being an annual report, interim report, earnings release, or any other detailed report type. Therefore, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory disclosures that do not fit other specific categories.

109年2月營業收入
Regulatory Filings Classification · 95% confidence The document is a summary report of monthly and cumulative net operating revenue figures for a company named 台亞, with data for February 2020 (民國109年02月). It includes percentage changes compared to the previous year and explanatory notes about accounting standards and reporting practices. The document is very short (767 characters) and contains no detailed financial statements or management discussion. It appears to be a brief financial data disclosure rather than a full financial report or earnings release. There is no indication of a conference call transcript, AGM materials, or regulatory certifications. Given the brevity and nature of the content, it fits best as a Regulatory Filing (RNS), which is a fallback category for miscellaneous filings that do not fit other specific categories.

Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings of company insiders, including directors, senior management, and their related parties. It shows the number of shares held, changes in holdings, and classifications of shares. The content is focused on insider share transactions and holdings rather than financial results, management commentary, or corporate governance policies. There is no indication of it being a full annual or quarterly report, earnings release, or any other type of report. The document is a report of personal share transactions and holdings by company directors and executives, which fits the definition of Director's Dealing (DIRS). The document length is substantial and contains actual data, not just an announcement or certification, so it is not Regulatory Filings (RNS) or Report Publication Announcement (RPA). Therefore, the appropriate classification is DIRS.
