A public limited company consists by default of three institutions: the Annual General Meeting, the Management Board and the Supervisory Board. The AG is managed autonomously by the Management Board. The Management Board may consist of one or more persons. The management board is appointed and supervised by the supervisory board. The Annual General Meeting in turn elects the Supervisory Board and, among other things, adopts resolutions on amendments to the Articles of Association. All investors can participate in the general meeting. The allocation of voting rights for resolutions and amendments to the Articles of Association is based on the proportion of shares held.
