2024年度董事会审计委员会对会计师事务所履行监督职责情况的报告
Audit Report / Information Classification · 95% confidence The document is a report from the Board Audit Committee regarding the supervision of the accounting firm for the 2024 fiscal year. It discusses the audit committee's evaluation of the auditor's qualifications, the audit plan, communication during the audit process, and the committee's oversight responsibilities. It does not contain the full audit report or financial statements but rather focuses on the audit committee's supervisory role and the audit process. This fits the definition of an Audit Report / Information (AR), which includes standalone audit reports and information about audit processes and oversight, excluding full annual reports. The document length is short but contains substantive content about audit supervision, not merely an announcement or certification. Therefore, the appropriate classification is AR with high confidence. FY 2024

董事会审计委员会工作制度（2025年4月）
Governance Information Classification · 95% confidence The document is titled '董事会审计委员会工作制度' which translates to 'Board Audit Committee Working System'. It details the structure, responsibilities, and procedures of the audit committee under the board of directors. The content focuses on governance, internal audit oversight, committee composition, meeting rules, and decision-making processes. There is no financial data, no report of financial results, no announcement of voting results, no legal proceedings, no capital changes, or other typical financial disclosures. The document is a governance-related internal regulation of the company, describing the audit committee's role and operation within the board structure. Therefore, it fits best under Governance Information (CGR). The document length is 2885 characters, which is relatively short but contains substantive governance content, not just an announcement or notice. Hence, the classification is CGR with high confidence.

It explicitly states that the full report is available on the website and urges investors to review it.

The document does not contain financial data or detailed report content, only a notice of the report's release.

The document also mentions that these resolutions will be submitted to the shareholders' meeting for approval. The document is a formal announcement of board meeting decisions rather than the full annual report or financial statements themselves. It is a typical board meeting resolution announcement that includes management and governance information but is not a full management report or annual report. Therefore, the best fitting classification is Board/Management Information (MANG).

It is a comprehensive report on internal control self-assessment rather than a general annual report or financial statement. It does not contain quarterly or annual financial statements but focuses on internal control evaluation and compliance with regulatory requirements. This type of document fits best under the category of Audit Report / Information (AR), which includes standalone audit reports and internal control evaluations, excluding full annual reports. The document length (11,930 characters) and detailed content confirm it is the report itself, not just an announcement or certification. Therefore, the appropriate classification is AR with high confidence. FY 2024
