Modern by tradition
We traditionally manage our business ourselves and responsibly and maintain this close and family-orientated character, while creating professional and independent structures at the same time. To this end, the Executive and Supervisory Boards serve as acting-responsible and advisory-controlling levels.
Taking responsibility
We have taken on the task of setting the direction as shareholders of our family business. We fulfil this responsibility and attach great importance to unity within the family on all key points. Our decisions are underpinned by recommendations from the Supervisory Board and external consultants.

Geared towards the future
