Participants are eligible on the first day of the quarter following the date of hire after one month of service and are allowed to make tax-deferred contributions up to 100% of annual compensation, subject to limitations specified by the Internal Revenue Code of 1986, as amended. Employer contributions consist of matching contributions and/or non-elective employer contributions. The Company match is 100% of the employee’s contribution up to 3% of the employee’s salary, and thereafter 50% of the employee’s contribution, until the employee’s contributions reach 5% of the employee’s salary. All contributions are immediately fully vested. The Company recorded contributions to its defined contribution plans of $4.4 million, $4.1 million and $4.0 million for the years ended December 31, 2018, 2017 and 2016, respectively.
