Regulatory Filings Classification · 95% confidence The document is an announcement from a credit rating agency (中证鹏元资信评估股份有限公司) regarding regulatory and legal developments affecting Shenzhen 特发信息股份有限公司, including receipt of a warning letter from the Shenzhen Securities Regulatory Bureau and a police investigation notice. It discusses the impact on credit ratings and ongoing monitoring but does not contain financial statements or detailed financial data.

Therefore, it fits best under Regulatory Filings (RNS), which is the fallback category for miscellaneous regulatory announcements and compliance updates.

关于公司2015年度审计报告（重新审计）的公告
Audit Report / Information Classification · 95% confidence The document is an announcement from Shenzhen Tefa Information Co., Ltd. regarding the re-audit of the 2015 annual audit report due to prior accounting errors that changed the nature of profit and loss. It references the issuance of a new audit report by an accounting firm and mentions related corrected financial statements. The document is relatively short (1069 characters) and primarily serves to inform about the completion and availability of the re-audit report and related corrected financial statements, rather than containing the full audit report itself. Therefore, it fits the category of an Audit Report / Information announcement rather than the full Annual Report or the full audit report document. The focus is on the audit report and related audit information, not on the entire annual report or other filings. Hence, the appropriate classification is AR (Audit Report / Information). FY 2015
