Defined Benefit Pension Plan

10. Defined Benefit Pension Plan

Our German subsidiary maintains an unfunded defined benefit pension plan which covers substantially all employees who joined the company prior to the plan’s closure to new participants in 2006. Participants are entitled to benefits in the form of retirement, disability and surviving dependent pensions. Benefits generally depend on years of service and the salary of the employees.
