关联交易管理办法
Governance Information Classification · 95% confidence The document is titled "斯达半导体股份有限公司 关联交易管理办法" which translates to "Related Party Transaction Management Measures" for the company. It is a detailed policy document outlining principles, definitions, decision-making procedures, disclosure requirements, and compliance rules regarding related party transactions. It references relevant laws and regulations such as the Company Law, Securities Law, and Shanghai Stock Exchange listing rules. The document is a governance and compliance manual rather than a financial report, earnings release, or announcement. It does not contain financial statements, audit opinions, or voting results. It is not a presentation or transcript. It is a governance-related internal rules document. Therefore, the most appropriate classification is Governance Information (CGR). The document length (7639 characters) supports it being a full policy document rather than a brief announcement or notice.

年报信息披露重大差错责任追究制度
Governance Information Classification · 95% confidence The document is titled '年报信息披露重大差错责任追究制度' which translates to 'Annual Report Information Disclosure Major Error Responsibility Pursuit System'. It outlines the company's internal policy and procedures for accountability related to major errors in annual report disclosures. The content focuses on rules, responsibilities, and penalties for errors in annual report information disclosure, referencing relevant laws and regulations. It does not contain actual financial data, financial statements, or the annual report itself. Instead, it is a governance or compliance document related to the annual report disclosure process. Given the nature of the document as a policy or governance framework concerning annual report disclosures, the most appropriate classification is Governance Information (CGR). The document length is 2389 characters, which is relatively short and consistent with a policy document rather than a full report or announcement.

第五届董事会第十二次会议决议公告
Board/Management Information Classification · 95% confidence The document is a formal announcement of resolutions passed at a board meeting of the company, including approval of governance-related rules and proposals to convene a shareholders' meeting. It contains voting results and details about amendments to company governance documents and internal rules. There is no financial data, earnings information, or report publication mentioned. The content focuses on board decisions and governance matters, which aligns with the category for Board/Management Information (MANG). The document length is short and it is not a report itself but a meeting resolution announcement, so it is not an Annual Report or Management Report. Therefore, the best classification is MANG with high confidence.

Audit Report / Information Classification · 95% confidence The document is titled '审计委员会年报工作规程' which translates to 'Audit Committee Annual Report Work Procedures'.

The content is procedural and governance-focused, detailing how the audit committee supervises the annual audit work, interacts with auditors, and ensures the integrity of the annual financial report. It does not contain actual financial data, audit results, or the audit report itself. Instead, it is a governance document describing the audit committee's work rules related to the annual report. Therefore, it fits best under 'Audit Report / Information (AR)' as it relates to audit committee procedures and audit oversight, but is not the annual report itself or a regulatory announcement. The document length is 2251 characters, which is relatively short and procedural, supporting this classification rather than a full report or announcement.
