This ad hoc report must be submitted to Bafin as soon as your share in an instrument exceeds or falls below a certain threshold in accordance with the Securities Trading Act. Once the threshold has been reached, the notification must be submitted to the supervisory authority within four trading days. If the relatively short notification period is exceeded, Bafin is authorised to impose case-related fines.

Since 2020, notifications must only be submitted electronically using the Bafin MVP portal. The WpHG voting rights notification must take into account not only directly held voting rights but also indirect voting rights and derivatives. In addition, short positions may be offset against long positions.
