111年企業社會責任報告書
Environmental & Social Information Classification · 95% confidence The document is a brief tabular summary from a public information observation station, listing a sustainability report for the company '台亞' (TASC) covering the period 111/01/01 to 111/12/31 (Taiwan calendar year equivalent to 2022). It references the GRI standards and a third-party audit by an accounting firm. The document includes links to the sustainability report files and contact information but does not contain the report itself or detailed financial data. The length is only 1229 characters, indicating it is a short announcement or summary rather than a full report. Given the content and length, this fits best as an Environmental & Social Information (SR) filing, which covers sustainability reports and ESG disclosures.

112年8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 the current and previous month, including limits and cumulative balances. It is a regulatory disclosure of financial status related to capital lending and guarantees, typical of periodic regulatory filings in Taiwan's public information observation station. The document is short (633 characters) and contains specific financial data but does not present a full financial report or analysis. It is not an annual or interim report, nor an earnings release or management discussion. It is a regulatory announcement of financial information related to capital and guarantees, fitting best under Regulatory Filings (RNS) as a general compliance disclosure.

112年8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 and year (August 2023, 民國112年08月) and compares current figures with the previous year. The document is short (775 characters) and appears to be a periodic financial summary rather than a full comprehensive report. It does not contain detailed financial statements or extensive analysis typical of an Interim/Quarterly Report (IR) but provides substantive financial data and analysis for a period shorter than a full fiscal year. Therefore, it fits best as an Interim / Quarterly Report (IR). Q3 2023

112年08月內部人持股異動(事後)
Director's Dealing Classification · 95% confidence The document consists of detailed tables listing shareholdings and changes in share ownership by insiders such as directors, chairpersons, general managers, and other executives. It includes specific data on stock types, amounts held at different times, and changes during the month. The content is focused on insider shareholdings and transactions, not on financial results, management commentary, or meeting materials. There is no indication of it being a full financial report, earnings release, or regulatory certification. The document is not a report publication announcement but a detailed insider shareholding disclosure. Therefore, it fits the category of Director's Dealing (DIRS), which covers reports of personal share transactions by company directors and executives (insider trades).

112年08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, supervisors, and senior management, with specific numbers of shares held, pledged shares, and related notes. It focuses on insider shareholdings and their changes or status. There is no indication of financial results, earnings, management discussion, or regulatory announcements beyond insider holdings. This type of document aligns with reporting of insider share transactions or holdings by directors and executives. Therefore, the document fits best under the category 'Director's Dealing' (DIRS). The document length is under 5,000 characters and contains detailed insider shareholding data, not just an announcement or certification, so it is not a Regulatory Filing or Report Publication Announcement.

The document is short (633 characters) and focused on specific financial data disclosures related to guarantees and lending balances, which fits best under Regulatory Filings (RNS) as a general regulatory announcement that does not fit other specific categories.
