The rule in brief
Companies must identify individuals who hold 25% or more of equity, profits or voting rights, or who otherwise control the company, and file them with SAMR. Changes must be updated within 30 days.
Common mistakes
- Stopping at the parent company instead of looking through to the individuals
- Forgetting control by other means, such as board appointment rights
- Not updating the filing after a group restructuring
