Retirement Benefits [Abstract] |
Pension Plans | Pension Plans The Company has defined benefit pension plans that cover certain French and German employees. Most of these acquired defined pension plans are unfunded; however, one of the pension plans in Germany is insured and the Company has pledged the insurance contracts to the pensioners. Accordingly, the contracts are now considered to be a plan asset. As the plan assets are insurance contracts, the Company does not control the investment strategy and thus cannot influence the return on investments. The insurance payments are guaranteed by the insurer and should the insurer default on its obligation, the security fund for insurance companies in Germany would assume the contracts. Plan benefits are provided in accordance with local statutory requirements. Benefits are based on years of service and employee compensation levels. Pension liabilities and charges are based upon various assumptions, updated annually, including discount rates, future salary increases, employee turnover, and mortality rates. The Company's French pension plan provides for termination benefits paid to covered French employees only at retirement, and consists of approximately one to five months of salary. The Company's German pension plan provides for defined benefit payouts for covered German employees following retirement. The aggregate net pension expense relating to these plans is as follows (in millions):

The Company expects total contributions to these plans to be approximately $1.2 million in fiscal 2019.
