Filing Released Lang Actions
深圳市特发信息股份有限公司关于公司债券将被实施投资者适当性管理的公告
Regulatory Filings Classification · 95% confidence The document is an announcement from Shenzhen Special Information Co., Ltd. regarding the implementation of investor suitability management for its bonds due to the company's audited 2021 net profit being negative. It references an audit report by Tianzhi International Accounting Firm but does not contain the full audit report itself. The document also mentions the suspension and resumption of trading of the bonds and the regulatory basis for the investor suitability management. The document length is short (1021 characters) and it primarily serves as a regulatory announcement about bond trading and investor restrictions, not a full financial report or audit report. It also directs readers to the company's 2021 annual report published elsewhere. Therefore, this document fits best as a Regulatory Filing (RNS) because it is a regulatory announcement about bond trading and investor suitability management, not the audit report or annual report itself.

Governance Information Classification · 95% confidence The document is a detailed company charter or articles of association, including chapters on general provisions, business scope, shares, shareholders and shareholders' meetings, board of directors, party committee, management, supervisory board, financial accounting system, profit distribution, audit, notices and announcements, mergers, amendments, and other special provisions. It references the company's establishment, share issuance, shareholder rights, and detailed procedures for shareholder meetings, including voting and resolutions. The document is not a financial report, earnings release, or announcement of voting results but rather a governance document outlining the company's internal rules and governance practices. Therefore, it fits the category of Governance Information (CGR).

关于前期会计差错更正的公告
Audit Report / Information Classification · 95% confidence The document is a detailed announcement from Shenzhen Tefa Information Co., Ltd. regarding the correction of prior period accounting errors affecting financial statements from 2015 to 2020. It includes extensive financial data adjustments, explanations of the errors, impacts on various years' financial statements, and opinions from the board, supervisory committee, independent directors, and an accounting firm audit report. The document is not a full annual report but a specific correction announcement with detailed financial restatements and audit confirmation. It is not a simple announcement of a report publication but contains substantive financial data and analysis related to prior period corrections. This fits the category of Audit Report / Information (AR), which covers standalone audit reports, accounting principles, and internal or regulatory stress tests, excluding full annual reports. Therefore, the classification is AR with high confidence. FY 2020

关于2022年度日常关联交易预计的公告
Regulatory Filings Classification · 95% confidence The document is an announcement regarding the expected daily related-party transactions for the fiscal year 2022 by Shenzhen Tefa Information Co., Ltd. It includes details about the nature, amounts, and pricing principles of these transactions, as well as independent directors' opinions and board resolutions. The document is relatively short (3,585 characters) and focuses on disclosure of related-party transactions rather than presenting comprehensive financial statements or detailed financial performance. It does not contain full financial data or analysis typical of an Annual Report (10-K) or Interim Report (IR). It is also not a certification or a regulatory compliance filing. The content fits best with a Regulatory Filing (RNS) as it is a general regulatory announcement about related-party transactions, which do not fit into other more specific categories.

Audit Report / Information Classification · 95% confidence The document is an audit report on the completion status of performance commitments related to a 2021 asset acquisition by Shenzhen Tefa Information Co., Ltd. It includes the auditor's responsibilities, management's responsibilities, audit opinion, and detailed financial performance analysis related to the asset purchase. The document is titled as an "audit report" and contains audit opinions and verification of financial data, which aligns with the definition of an Audit Report / Information (AR). The document length is 2697 characters, which is short but contains substantive audit content rather than just an announcement or certification. Therefore, it is classified as an Audit Report / Information (AR). FY 2021

2021年年度财务报告
Annual Report Classification · 100% confidence The document is titled as the "2021 年年度财务报告全文" which translates to "2021 Annual Financial Report Full Text" for Shenzhen Tefa Information Co., Ltd. It contains detailed financial statements including consolidated and parent company balance sheets, profit and loss statements, cash flow statements, audit report with unqualified opinion, and notes on key audit matters. The presence of comprehensive financial data for the full fiscal year 2021, audit opinion, and detailed financial disclosures clearly indicate this is a full Annual Report. The document length is substantial (15,000 characters), and it is not merely an announcement or a certification. Therefore, the correct classification is Annual Report (10-K). FY 2021
