Dec. 31, 2021
Postemployment Benefits [Abstract]
Post-Employment Benefits	Post-Employment Benefits We have a 401(k) Plan that covers substantially all of our employees in the U.S. Effective January 1, 2017, we have elected to match 100% of employees' contributions up to a maximum of 3% of an employee's annual salary. Matching contributions are immediately vested. For the years ended December 31, 2021, 2020 and 2019, we contributed approximately $9.8 million, $7.4 million and $5.1 million for the matching contributions, respectively.

The entire disclosure for postemployment benefits, which may include supplemental unemployment benefits, obligations recognized for all types of benefits provided to former or inactive employees, their beneficiaries, and covered dependents after employment but before retirement. Disclosure may also include discussion that an obligation for postemployment benefits is not accrued in accordance with regulation only because the amount cannot be reasonably estimated.
