Education, activities and vested interests
The summary on the following pages contains basic information about the career paths and education of the individual IEC-members. It also discloses the mandates held by each member outside the Group as well as any further significant activities and permanent positions in significant interest groups.
Number of permissible activities
According to Art. 22e of the Articles of Association, each member of the IEC may hold no more than nine mandates as a director or officer of legal entities outside the Implenia Group (no more than four of which may be held in exchange-listed companies), which are to be registered in the Swiss Commercial Register or a similar foreign register, providing that they are approved on a case-by-case basis by the NCC. If mandates are held in different legal entities of one and the same corporate group or are held on behalf of a corporate group or a legal entity, then these will be counted in their entirety as one mandate in each case. It is permissible to exceed the foregoing limits for short periods. The Articles of Association with the exact wording of the above-cited provision can be viewed on Implenia's website.
