Filing Released Lang Actions
关于使用自有闲置资金进行投资理财的公告
Regulatory Filings Classification · 95% confidence The document is a company announcement regarding the use of idle funds for investment purposes. It details the investment plan, risk analysis, impact on the company, and includes independent directors' opinions. It is not a financial report, earnings release, or regulatory certification. The document is relatively short (2019 characters) and serves as an official announcement of a board decision and investment policy rather than a detailed financial report or audit. It does not fit into categories like Annual Report, Interim Report, or Earnings Release. It is best classified as a Regulatory Filing (RNS) because it is a general regulatory announcement about company activities that does not fit other specific categories.

募集资金专项存储及使用管理制度（2015年12月）
Governance Information Classification · 95% confidence The document is titled '募集资金专项存储及使用管理制度' which translates to 'Special Management System for the Storage and Use of Raised Funds'. It is a detailed internal policy document of 河南四方达超硬材料股份有限公司 (Henan Sifangda Superhard Materials Co., Ltd.) regarding the management, storage, and use of funds raised through securities issuance. The document references relevant laws, regulations, and stock exchange rules governing the use of raised funds, including procedures for storage, usage, supervision, and reporting. It does not contain financial statements, earnings data, or audit opinions. It is not an announcement or a brief summary but a comprehensive internal governance and compliance document related to capital management. Therefore, it fits best under Governance Information (CGR), which covers reports detailing the company's internal rules, board structure, and governance practices, including policies on capital use and compliance.

关于变更会计师事务所的公告
Audit Report / Information Classification · 95% confidence The document is an announcement regarding the change of the company's auditor (accounting firm) for the fiscal year 2015. It details the previous auditor, the new auditor to be appointed, and includes opinions from independent directors. The document does not contain any financial statements or audit results itself, but rather informs about the auditor change decision and related approvals. The document length is short (1403 characters) and it is clearly an announcement, not the audit report itself. Therefore, it fits best under the category of Audit Report / Information (AR), which includes standalone audit reports and related announcements about audit firms, but since this is specifically about changing the auditor, it is an audit-related announcement. Given the content, AR is the most appropriate classification with high confidence. FY 2015

This fits the category of Board/Management Information (MANG), which covers announcements of changes or decisions by the company's board or senior management. The document length is short (1327 characters) and it is not an announcement of a report publication or a regulatory filing. Therefore, the correct classification is MANG with high confidence.
