Retirement Benefits [Abstract]
Retirement Plans	Retirement PlansWe have a defined contribution 401(k) retirement and savings plan (the “401(k) Plan”) to provide retirement benefits for all eligible employees. All employees who have completed forty-five days of service and are at least twenty-one years of age are eligible to participate in the 401(k) Plan. The 401(k) Plan allows eligible employees to make salary-deferred contributions up to 75% of their annual compensation, as defined, and subject to certain Internal Revenue Service limitations. Employer contributions vest at 25% per year, over four years. For the years ending December 31, 2019, 2018 and 2017, we incurred $5.5 million, $4.7 million and $3.3 million, respectively, in contribution expense related to the employer matching contributions. We are obligated to make plan contributions for the employees of certain of our wholly-owned foreign subsidiaries. For the years ending December 31, 2019, 2018 and 2017, we incurred $1.5 million, $1.3 million and $0.9 million, respectively, in contribution expense related to our foreign subsidiaries.
