Share-based Payment Arrangement [Abstract]

Share-based Payment Arrangement

The income tax benefit related to stock-based compensation expense was $8.6 million, $9.0 million and zero for the year ended December 31, 2022, 2021 and 2020, respectively. There was no income tax benefit related to stock-based compensation expense realized in 2020 due to a full valuation allowance on the Company’s United States net deferred tax assets during that year. See Note 8, Income taxes, for additional details.

On December 31, 2022, total unearned stock-based compensation of $53.2 million related to stock options, RSUs, PSUs and ESPP shares is expected to be recognized over a weighted-average period of 1.98 years.
