捷捷微电2024年度独立董事述职报告（袁秀国）
Board/Management Information Classification · 95% confidence The document is a detailed annual report by an independent director of a company, describing their duties, attendance at meetings, communication with auditors, and oversight activities during the year 2024. It includes references to compliance with laws, attendance at board and committee meetings, review of financial reports, and involvement in major company decisions such as share issuance and remuneration. The document is a formal report on the independent director's performance and activities for the year, not a general annual report or financial statement. This fits the category of Board/Management Information (MANG), which covers announcements related to changes or reports from company directors or senior management. The document length is under 5,000 characters, but it is a substantive report, not just an announcement of a report publication or certification. Therefore, the best classification is MANG with high confidence.

Regulatory Filings Classification · 95% confidence The document is a special opinion from the board of Jiangsu Jiejie Microelectronics Co., Ltd. regarding the independence of its independent directors, referencing regulatory guidelines for independent directors. It is a regulatory compliance statement about director independence, not a financial report, meeting material, or voting result. The document is short (419 characters) and focuses on governance compliance. This fits best under Regulatory Filings (RNS) as it is a regulatory announcement that does not fit other specific categories.
