Director's Dealing Classification · 95% confidence The document is a short tabular report showing a pledge or release of shares by a company director or executive (副總經理本人 means Vice General Manager himself). It lists details such as the number of pledged shares, dates, and pledgee information. This matches the definition of Director's Dealing, which reports personal share transactions by company directors and executives. The document length is very short (327 characters), consistent with a brief insider transaction report. Therefore, the classification is DIRS with high confidence.

Major Shareholding Notification Classification · 95% confidence The document is a statistical table showing the shareholding situation of overseas and mainland China investors, including details on shareholding changes due to cash capital increase. It includes specific stock codes, share counts before and after changes, and dates related to shareholding records. The document is short (1068 characters) and focuses on shareholding data rather than financial results or management commentary. It does not contain financial statements or detailed analysis, nor is it an announcement of a meeting or voting results. The content aligns with notifications about changes in significant share ownership levels or shareholding structure. Therefore, the most appropriate classification is Major Shareholding Notification (MRQ).

Share Issue/Capital Change Classification · 95% confidence The document contains detailed information about the company's capital structure, including authorized capital, paid-in capital, and sources of capital such as cash capital increase and private placement of new shares. It is a specific announcement about share capital changes rather than a full financial report or an announcement of a report. The document length is short (857 characters) and focuses on capital changes, indicating it is a Share Issue/Capital Change announcement.

Director's Dealing Classification · 100% confidence The document is a short tabular report showing a change in pledged shares by a company director or executive (副總經理本人 means Vice General Manager himself). It lists details such as the number of shares pledged and released, the pledgee, and dates. This matches the definition of a Director's Dealing report, which covers personal share transactions by company directors and executives. The document length is very short (327 characters), but it contains specific data about share pledging activity by a director, not just an announcement or certification. Therefore, it should be classified as DIRS.

114年第2季海外子公司投資
Interim / Quarterly Report Classification · 85% confidence The document contains detailed financial data related to investments in overseas subsidiaries, including shareholding percentages, original investment amounts, investment balances, and recognized investment gains or losses for the current period. The data is presented in a tabular format with notes explaining accounting treatments. The document length is 1411 characters, which is relatively short and does not appear to be an announcement of a report but rather a financial data disclosure. The content aligns with detailed financial reporting on investments, which is typical of an Interim / Quarterly Report (IR) or a segment of such a report. There is no indication that this is a full Annual Report (10-K) or a simple announcement. Given the nature of the data and the period reference (114年2季, which corresponds to the second quarter of the 114th year in the Taiwanese calendar), this is consistent with an Interim / Quarterly Report. Therefore, the most appropriate classification is IR (Interim / Quarterly Report).

114年第2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 the company 光罩. It includes specific financial figures, investment methods, and regulatory limits, but it is relatively short (1535 characters) and appears to be a regulatory disclosure rather than a full financial report. There is no indication that this is a full annual or interim report, audit report, or earnings release. The document is a regulatory disclosure of investment information, which fits best under Regulatory Filings (RNS) as it does not match other more specific categories and is a compliance-related announcement.
