Prof. Dr. Dr. Heinzl’s decision to resign was not the result of any disagreement with the Company on any matters relating to the Company’s operations, policies or practices.

On April 4, 2017, the Supervisory Board approved the nomination to the Supervisory Board of Mr. Eberhard Weiblen to be elected at the AGM to serve until the AGM to be held in 2019.
