Income Tax Disclosure [Abstract]  
Income Taxes Income TaxesThe Company uses the estimated annual effective tax rate approach to determine the provision for income taxes. The estimated annual effective tax rate is based on forecasted annual results and may fluctuate due to differences between the forecasted and actual results, changes in valuation allowances, and any other transactions that result in differing tax treatment.
The Company's income tax expense and effective tax rate were as follows:
Three Months Ended September 30,Nine Months Ended September 30,
2022202120222021
Income tax expense$(12)$(1,052)$574 $151 
Effective tax rate0.1 %1.1 %(0.6)%(0.2)%
The Company’s estimated annual effective income tax rate for the three and nine months ended September 30, 2022 and 2021 differed from the statutory rate primarily due to non-deductible executive compensation, stock-based compensation, differences in tax rates in state and foreign jurisdictions, the valuation allowance, and other permanent items.
