关于拟续聘会计师事务所的公告
Regulatory Filings Classification · 95% confidence The document is an announcement regarding the proposed reappointment of an accounting firm (auditor) for the company for the 2021 fiscal year. It details the auditor's qualifications, independence, audit fees, and the approval process by the board and audit committee. It does not contain any financial statements or audit reports themselves, but rather is a notice about the auditor appointment to be approved at the upcoming shareholders' meeting. The document length is under 5,000 characters and is clearly an announcement rather than a full audit report or annual report. Therefore, it fits best under the category of Audit Report / Information (AR) since it relates to audit matters but is not a full annual report or audit report itself. However, since it is specifically about the auditor appointment and not the audit report results, it is more appropriate to classify it as Regulatory Filings (RNS) as a general regulatory announcement about auditor appointment, which does not fit other categories better. Hence, the best classification is Regulatory Filings (RNS).

长江证券承销保荐有限公司关于上海凯鑫分离技术股份有限公司2020年度募集资金存放与使用情况的专项核查意见
Audit Report / Information Classification · 95% confidence The document is a detailed report from a securities underwriting and sponsorship company regarding the 2020 annual special verification opinion on the deposit and use of raised funds by Shanghai Kaixin Separation Technology Co., Ltd. It includes detailed financial figures about the amount raised, usage, bank accounts, and compliance with regulatory requirements. It also contains an auditor's verification opinion and a detailed table of fund usage. The document is focused on the management and use of funds raised through a public offering, which aligns with a specialized audit or verification report rather than a full annual report or earnings release. The presence of an auditor's opinion and detailed fund usage verification indicates this is an Audit Report / Information type document, specifically a special verification report on raised funds usage. The document length (5498 characters) is sufficient to contain substantive content, not just an announcement or certification. Therefore, the appropriate classification is AR (Audit Report / Information). FY 2020

2020年度募集资金存放与使用情况的专项报告
Capital/Financing Update Classification · 95% confidence The document is titled as a "2020年度募集资金存放与使用情况的专项报告" which translates to "2020 Annual Special Report on the Deposit and Use of Raised Funds." It details the company's fundraising activities, the amount raised, the use of the funds, bank accounts holding the funds, and compliance with regulatory requirements. It references approvals from the China Securities Regulatory Commission and Shenzhen Stock Exchange, and includes detailed financial figures related to the raised capital and its usage. The document is a specialized report focused on the management and use of capital raised through a public offering, not a general annual report or earnings release. This matches the description of a Capital/Financing Update (CAP) which covers updates on company fundraising and capital structure changes. The document length is 4638 characters, which is sufficient to be a report rather than a brief announcement. Therefore, the appropriate classification is CAP with high confidence.

2020年年度报告摘要
Annual Report Classification · 100% confidence The document is titled as the "2020 年年度报告摘要" which translates to "2020 Annual Report Summary". It contains detailed financial data for the year 2020, including revenue, net profit, assets, and shareholder information. It also includes management discussion and analysis of business operations, industry environment, and company strategy. The document references the auditor's opinion and detailed accounting policies, which are typical components of an annual report. The length of the document (over 11,000 characters) and the presence of substantive financial data and analysis confirm it is the report itself, not just an announcement or summary. Therefore, this document fits the definition of an Annual Report (10-K). FY 2020

Notice of Dividend Amount Classification · 95% confidence The document is an announcement regarding the company's 2020 profit distribution plan, including details on dividends per share, legal compliance, and approvals by the board and supervisory committee. It does not contain full financial statements or comprehensive financial performance data but focuses on the dividend distribution proposal and related approvals.

Therefore, it fits best under the category of Notice of Dividend Amount (DIV).

2020年度内部控制自我评价报告
Audit Report / Information Classification · 95% confidence The document is titled '2020年度内部控制自我评价报告' which translates to '2020 Annual Internal Control Self-Evaluation Report'.

The content focuses on internal control evaluation and does not present full financial statements or audit opinions. Given the nature of the document as an internal control self-evaluation report, it fits best under the category of Audit Report / Information (AR), which includes applied accounting principles and internal control results but excludes full annual reports. The document length is 2862 characters, which is sufficient for a substantive report rather than a brief announcement. Therefore, the classification is AR with high confidence. FY 2020
