12. Employee Retirement Savings Plan and Other Employee Matters
Our Employee Retirement Plan (the “Retirement Plan”) is an Internal Revenue Code Section 401(k) Retirement Savings Plan. Historically, all U.S.-based employees at least 21 years of age with at least three months of employment with us are eligible to participate in the Retirement Plan. The Retirement Plan provides for an annual employer discretionary matching contribution. In December 2013, we approved a basic matching contribution equal to 100% of each participant’s contributions not exceeding 3% of each participant’s compensation, plus 50% of the participant’s contributions in excess of 3% but not in excess of 5% of the participant’s compensation. Further, we may make additional discretionary matching contributions not to exceed 4% of each participant’s compensation. During the years ended December 31, 2017, 2016 and 2015, expenses recorded for our contributions to the Retirement Plan totaled $5.1 million, $5.0 million and $4.8 million, respectively.
