Defined Benefit Plan [Abstract] |
BENEFIT PLANS | (9.) BENEFIT PLANS Savings Plan The Company sponsors a defined contribution 401(k) plan (the “Plan”), for its U.S. based employees. The Plan provides for the deferral of employee compensation under Internal Revenue Code §401(k) and a Company match. The Company matches $0.50 per dollar of participant deferral, up to 6% of the compensation of each participant. Contributions from employees, as well at those matched by the Company, vest immediately. Net costs related to defined contribution plans were $6.8 million in 2018, $6.0 million in 2017 and $4.6 million in 2016. Defined Benefit Plans The Company is required to provide its employees located in Switzerland and Mexico certain statutorily mandated defined benefits. Under these plans, benefits accrue to employees based upon years of service, position, age and compensation. The defined benefit pension plan provided to the Company’s employees located in Switzerland is a funded contributory plan, while the plans that provide benefits to the Company’s employees located in Mexico are unfunded and noncontributory. The assets of the Switzerland plan are held at an AA- rated insurance carrier who bears the pension risk and longevity risk, and will be used to cover the pension liability for the remaining retirees of the Swiss plan, as well as the remaining employees at that location. The liability and corresponding expense related to these benefit plans is based on actuarial computations of current and future benefits for employees. (9.)
