Subsequent Events [Abstract]
Subsequent Events	Subsequent EventsOn October 26, 2021, our board of directors approved stock options to our chief executive officer (“CEO”) a long-term performance-based option award (the “Award”), which will vest in eight equal tranches based on service and achievement of financial performance and market conditions, with a total award value of approximately $150 million if all service, performance and market conditions are met. However, no portion of the Award will vest prior to two years from grant date and grantee must remain in continuous service as either the CEO or Executive Chairman of the Company to be eligible. The performance and market condition for a particular tranche may be achieved at different points in time and in any order but will become eligible to vest only when all service, performance and market conditions for the respective tranche are met. The performance and market condition must be achieved by September 30, 2026 and the Award will expire on October 29, 2031.
