115年3月背書保證與資金貸與
Regulatory Filings Classification · 1% confidence The document is a routine disclosure of the company’s and its subsidiaries’ fund lending balances and guarantee/endorsement exposures (tables showing zero balances). It does not present financial statements as a full report (e.g., Annual or Interim Report), nor is it an AGM material, call transcript, earnings release, dividend notice, major shareholding, management change, or other specific category. It is a standard regulatory submission of guarantee/endorsement data under public disclosure requirements. This falls under the fallback category “Regulatory Filings (RNS).”

115年03月內部人持股異動(事後)
Director's Dealing Classification · 1% confidence The document is a public disclosure of individual shareholdings and monthly changes for the company’s directors, chair, general manager, independent directors and other key insiders (including spouses and related parties). It details “本月增加” and “本月減少” share movements by each insider. This matches the definition of a Director’s Dealing report (insider transactions and holdings).

115年03月董事會成員及持股
Director's Dealing Classification · 1% confidence The document is a regulatory disclosure from Taiwan’s Market Observation Post System showing a detailed schedule of insiders’ (directors, independent directors, managers) current and pledged shareholdings. This corresponds to insider shareholding disclosures rather than a financial report or AGM material. Under the taxonomy, the closest match is a Director’s Dealing–type filing which covers insider share transactions and holdings disclosures. Therefore, we classify it as DIRS.

公司基本資料
Regulatory Filings Classification · 1% confidence The document is a basic company profile disclosure filed via Taiwan’s Market Observation Post System (MOPS), listing corporate details (stock code, address, contacts, share capital, auditors, IR contacts, etc.). It contains no financial results, dividend notice, governance changes, or other specialized report content. It is a general regulatory announcement of company information and does not fit into specific categories like Board changes, Dividends, or ESG reports. Hence it falls into the fallback category ‘Regulatory Filings’.
