2020年度内部控制自我评价报告
Audit Report / Information Classification · 95% confidence The document is titled '年度内部控制自我评价报告' which translates to 'Annual Internal Control Self-Evaluation Report' for the year 2020. It discusses the company's internal control evaluation, including financial and non-financial internal control effectiveness, governance structure, risk management, and compliance with regulatory standards. The document is detailed and contains substantive content about internal control evaluation and results, not merely an announcement or certification. It is not a full annual report (10-K) but a specific report on internal control evaluation, which aligns with the definition of an Audit Report / Information (AR) as it relates to audit and internal control results. The document length (8718 characters) supports it being a full report rather than a brief announcement. Therefore, the most appropriate classification is AR (Audit Report / Information). FY 2020

Audit Report / Information Classification · 95% confidence The document is titled as an announcement regarding the reappointment of the audit firm for the fiscal year 2021. It details the qualifications, experience, and independence of the audit firm, the audit fees, and the approval process by the board and supervisory committee. It does not contain actual audited financial statements or audit reports but rather announces the intention and approval to rehire the audit firm for the upcoming audit period. The document length is 4034 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this document fits the category of an Audit Report / Information announcement about the audit firm reappointment rather than the audit report itself. According to the filing definitions, standalone audit reports or audit-related announcements fall under the Audit Report / Information (AR) category. Hence, the appropriate classification is AR with high confidence. FY 2021
