401(k) Plan

We offer a 401(k) plan to which employees may contribute earnings subject to IRS limitations.  We match 100% of an employee’s contribution, up to 6% of compensation, as defined by the plan, which is vested immediately.  During 2019, 2018 and 2017, our matching contributions to the 401(k) plan were approximately $6.3 million, $6.2 million and $7.1 million, respectively.
