The document does not contain financial statements or detailed financial data, nor is it an announcement of a report publication.

《董事、高级管理人员薪酬管理制度》（2026年4月）
Remuneration Information Classification · 95% confidence The document is titled '董事、高级管理人员薪酬管理制度' which translates to 'Remuneration Management System for Directors and Senior Management'. It details the principles, standards, management, performance evaluation, adjustment, and clawback mechanisms of remuneration for directors and senior management personnel. It references relevant laws and regulations, and discusses the structure and payment of compensation, performance assessment, and incentive plans. There is no indication that this is an announcement or a brief summary; rather, it is a detailed policy document on remuneration. This matches the definition of Remuneration Information (DEF 14A), which covers reports detailing compensation for top executives and directors. The document length (4804 characters) and content confirm it is a substantive remuneration report, not a brief announcement or certification. Therefore, the correct classification is DEF 14A with high confidence.
