Employee Benefit Plan
The Company sponsors a defined contribution 401(k) plan (the Plan) in which substantially all U.S. employees are eligible to participate. Through April 30, 2016, the Company matched 100 percent of each participant’s pre-tax contributions in an amount not exceeding 4 percent of the participant's compensation and 50 percent of each participant’s pre-tax contributions in an amount not exceeding 2 percent of the participant's compensation, up to the maximum amount of contributions allowed by law.  The Company match was suspended on May 1, 2016. The costs of matching contributions to the Plan were $1.1 million, $4.0 million and $4.7 million in 2016, 2015 and 2014, respectively. Employees become 100 percent vested in the employer match contributions immediately upon participation in the Plan.
