海油工程2025年度独立董事述职报告（辛伟）
Board/Management Information Classification · 95% confidence The document is a detailed independent director's annual report for the year 2025 from a Chinese company, 海洋石油工程股份有限公司. It includes extensive information about the director's duties, attendance at board and committee meetings, opinions on company matters, and detailed attachments about board resolutions, risk assessments, financial audits, internal controls, and management changes. The content is comprehensive and covers the director's oversight and governance activities throughout the year, including financial and operational reviews. This type of document is a formal report by an independent director on their annual duties and observations, which is typically part of governance and management reporting rather than a full annual report or audit report. It is not a transcript, earnings release, or a simple announcement. Given the focus on the independent director's role, duties, and opinions on governance and company operations, the best fitting category is Board/Management Information (MANG).

海油工程2025年年度报告
Annual Report Classification · 100% confidence The document is titled "海洋石油工程股份有限公司2025 年年度报告" which translates to "Offshore Oil Engineering Co., Ltd. 2025 Annual Report." It contains detailed financial data, management discussion and analysis, company overview, governance, and audited financial statements. The document length is substantial (15,000 characters), indicating it is the full report rather than a brief announcement. It includes audited financial figures, management commentary, risk disclosures, and corporate governance information typical of an annual report. The presence of an auditor's unqualified opinion and detailed financial metrics further confirms this classification. Therefore, this document is the official yearly report covering company activity and full financial performance, matching the definition of an Annual Report (10-K).

海油工程董事会审计委员会对中审众环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 detailed report from the Board Audit Committee regarding the audit work performed by the accounting firm 中审众环会计师事务所 for the fiscal year 2025. It discusses the audit plan, supervision during the audit process, evaluation of the audit firm's independence, professional capability, and audit procedures, and concludes with an opinion on the audit work and the audit report issued. The document is not the full annual report (10-K) but a standalone audit-related report focusing on the audit process and results. It matches the description of an Audit Report / Information (AR) filing, which includes standalone audit reports and related audit information. The document length is 2027 characters, which is consistent with a detailed audit report rather than a brief announcement or certification. Therefore, the correct classification is AR with high confidence.
