2019年年度审计报告
Audit Report / Information Classification · 100% confidence The document is titled as an "审计报告" (Audit Report) for the year 2019 of 烟台正海生物科技股份有限公司. It contains detailed auditor opinions, audit basis, key audit matters, management responsibilities, and extensive financial statements including balance sheets, profit and loss statements, and cash flow statements. The presence of detailed audit procedures and auditor's opinion on the financial statements confirms this is a standalone audit report rather than a full annual report or other filing. The document length is substantial (15,000 characters) and contains actual financial data and audit details, not just an announcement or certification. Therefore, the document fits the definition of an Audit Report / Information (AR). FY 2019

关联交易管理制度（2020年4月）
Governance Information Classification · 95% confidence The document is titled '关联交易管理制度' which translates to 'Related Party Transaction Management System' and details the rules, definitions, and procedures for managing related party transactions within the company. It references relevant laws and stock exchange listing rules, outlines thresholds for approval by management, board, and shareholders, and specifies disclosure and voting procedures. The content is a governance policy document rather than a financial report, earnings release, or announcement. It does not contain financial statements or results, nor is it a notice or announcement of a report. It is a governance-related internal rules document about related party transactions, fitting the Governance Information (CGR) category.

董事、监事和高级管理人员持股变动管理制度（2020年4月）
Governance Information Classification · 95% confidence The document is titled '董事、监事和高级管理人员持股变动管理制度' which translates to 'Management System for Shareholding Changes of Directors, Supervisors and Senior Management'. It details rules and procedures for managing shareholdings and transactions by company directors, supervisors, and senior management, including reporting, disclosure, trading restrictions, and penalties for violations. It references relevant laws and regulatory bodies such as the Shenzhen Stock Exchange and China Securities Regulatory Commission. The content is a governance policy document focused on insider shareholding management rather than a report of financial results, audit, or meeting materials. It is not an announcement or a brief notice but a detailed internal governance document. Therefore, it fits best under Governance Information (CGR).

广发证券股份有限公司关于公司2019年年度跟踪报告
Regulatory Filings Classification · 95% confidence The document is titled as a '2019 Annual Tracking Report' by a sponsoring securities company regarding a specific company. It details the sponsor's review and supervision activities, including information disclosure, internal controls, fundraising supervision, governance, and other compliance matters. The document does not contain financial statements or detailed financial analysis but rather a summary of oversight and compliance activities related to the company for the year 2019. The length is 2390 characters, which is relatively short and more consistent with a report or summary rather than a full annual report or interim report. It is not a certification or a voting result announcement. The content aligns with a regulatory or compliance oversight report by a sponsor rather than a financial report or earnings release. Therefore, the best fitting category is Regulatory Filings (RNS), as it is a regulatory compliance related document that does not fit into other specific categories like Annual Report or Interim Report.

关于续聘2020年度审计机构的公告
Audit Report / Information Classification · 95% confidence The document is titled as an announcement regarding the reappointment of the audit firm for the 2020 fiscal year. It details the qualifications, experience, and independence of the audit firm, the audit fees, and the approval process by the board and audit committee. The document does not contain any actual audit report or financial statements but is an announcement about the appointment of the auditor for the upcoming audit period. The document length is 3491 characters, which is relatively short and consistent with an announcement rather than a full audit report. Therefore, this document fits best into the category of Audit Report / Information (AR) as it relates to audit matters but is not a full annual report or audit report itself. However, since it is an announcement of auditor reappointment and not the audit report itself, it is more precisely an Audit Report / Information (AR) filing rather than an Annual Report (10-K) or Report Publication Announcement (RPA). FY 2020
2020-04-09 Chinese
关于会计政策变更的公告
Regulatory Filings Classification · 95% confidence The document is titled '会计政策变更公告' which translates to 'Accounting Policy Change Announcement'. It details the company's change in accounting policies due to new accounting standards issued by the Ministry of Finance, including the new revenue recognition standard and financial statement format adjustments. The document includes the date of the board meeting approving the change, the reasons for the change, the impact on financial statements, and opinions from the supervisory board and independent directors. The document is relatively short (2699 characters) and serves as an announcement of the accounting policy change rather than a full financial report or audit report. It does not contain actual financial statements or detailed financial data but rather informs stakeholders about the policy change and its approval process. Therefore, it is best classified as a Regulatory Filing (RNS), which is the fallback category for announcements that do not fit other specific categories and are not full reports themselves.
