The pension plan for all members of the Board of Management is based on an income and age-related defined contribution plan. The available premium is invested with a pension fund. The pension payment at pension age depends on the premiums received and the investment results during the period. The premium percentages to be paid for the Board member concerned are fixed by the Supervisory Board. The premiums are paid over the base salary in the current year and the short-term incentive of the previous year. The premiums will therefore vary depending on the performance during the previous year. External reference data can be used in determining market competitive levels of pension arrangements. If applicable, pension rights built up in the period preceding Board membership can be taken into account to limit the premiums to be paid to the relevant Board member. In addition, members of the Board of Management pay a personal contribution.
