Official Announcements contain no enforcement, payment order or tax authority notices about the company.

Official Announcements (CC BY-SA 4.0). Enforcement proceedings, payment orders or tax decisions are published there only if they cannot be delivered to the company otherwise. The enforcement register is not public, so the absence of a notice does not mean there are no claims.
