2025年度董事会审计委员会履职情况报告
Audit Report / Information Classification · 95% confidence The document is titled '2025年度董事会审计委员会履职情况报告' which translates to '2025 Annual Report on the Board Audit Committee's Performance'. It details the audit committee's activities, meetings, oversight of financial reporting, internal controls, and external audit supervision for the year 2025. The content focuses on the audit committee's duties and their fulfillment during the year, rather than presenting full financial statements or a comprehensive annual report. The document length is 2586 characters, which is relatively short and more consistent with a committee report rather than a full Annual Report (10-K). It is not a certification or a brief announcement but a detailed report on audit committee activities. This fits best with the category 'Audit Report / Information (AR)', which includes standalone audit reports and related committee reports. Therefore, the document should be classified as AR with high confidence. FY 2025

拟续聘2026年度会计师事务所公告
Audit Report / Information Classification · 95% confidence The document is an announcement regarding the proposed reappointment of an accounting firm (信永中和会计师事务所) for the 2026 fiscal year audit. It details the firm's background, integrity records, audit fees, and the board and audit committee's approval process. There is no actual audit report or financial statements included, only information about the appointment process and related approvals. The document length is 3146 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this document is best classified as an Audit Report / Information (AR) type, as it relates to audit firm appointment and audit-related disclosures but is not a full annual report or audit report itself. However, since it is about the audit firm appointment and related information, AR is the most appropriate category rather than a regulatory filing or report publication announcement. FY 2026

董事会审计委员对会计师事务所履行监督职责情况报告
Audit Report / Information Classification · 95% confidence The document is a report from the company's Board Audit Committee on the supervision of the accounting firm (信永中和) for the 2025 annual audit. It details the audit firm's qualifications, the procedures followed in appointing the auditor, and the committee's evaluation of the auditor's performance and independence. The document does not contain the audit report itself or detailed financial statements but rather a supervisory report on the auditor's role and conduct. This fits the definition of an Audit Report / Information (AR), which includes standalone audit reports and information about the audit process and oversight, excluding full annual reports. The document length is 1561 characters, which is short but contains substantive content about audit supervision, not just an announcement or certification. Therefore, the appropriate classification is AR with high confidence. FY 2025

It also includes information about board and management changes, remuneration, and compliance with regulatory requirements. The document is a detailed report on the independent director's activities and oversight during the fiscal year, which is a form of management or board information rather than a full annual report or audit report. It is not a simple announcement or certification but a substantive report on governance and board activities. Therefore, the most appropriate classification is Board/Management Information (MANG). The document length (4944 characters) supports it being a full report rather than a brief announcement.

It is not an annual report (10-K), audit report (AR), or interim report (IR), nor is it a simple announcement or certification.
