401(k) Profit-Sharing Retirement Plan

The Company maintains a contributory 401(k) profit-sharing retirement plan covering substantially all U.S. employees. At its discretion, the Company may match up to 50% of the first 6% of eligible wages contributed by the participants. This match was indefinitely suspended as of January 1, 2017. Company contributions, net of forfeitures, which currently consist of cash and may include the Company’s stock, were funded and charged to operations in the amounts of $0.0 million, $2.0 million, and $3.0 million for 2017, 2016, and 2015, respectively.

Other Retirement Plans

The Company maintains various other defined contribution retirement plans covering substantially all of the remaining European employees. Company contributions charged to operations were $0.2 million in 2017, $0.1 million in 2016, and $0.2 million in 2015.

Employee Health Insurance

The Company provides various health insurance plans for its employees, including a self-insured plan for its salaried and hourly employees in the U.S. In 2015, the Company began offering compliant healthcare coverage as required under The Patient Protection and Affordable Care Act (PPACA). Where possible, the Company has passed the cost of this coverage on to its customers where the employees that elect this coverage are engaged.
