Retirement Plans

The Company provides eligible employees the opportunity to participate in defined-contribution savings plans (commonly known as 401(k) plans), which permit contributions on a before-tax basis. Generally, salaried employees and certain hourly employees are eligible to participate in the plans. Under most plans, the employee may contribute to various investment alternatives. In certain plans, the Company matches a portion of the employees’ contributions. The Company’s matching contributions to these defined-contribution savings plans totaled $4.9 million in 2013, 2014, and 2015.
