Income Taxes

13. Income Taxes

The provision for income taxes in interim periods is determined using an estimate of the Company’s annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, the Company updates its estimate of its annual effective tax rate, and if the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period. The quarterly provision for income taxes, and estimate of the Company’s annual effective tax rate, are subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how the Company conducts business, and tax law developments.

The provision effective tax rate for the three months ended March 31, 2022 and 2021 was 0.1% and 0.0%, respectively. The deferred income taxes for the three months ended March 31, 2022 was primarily due to discrete items.

The realization of deferred tax assets is dependent upon a variety of factors, including the generation of future taxable income, the reversal of deferred tax liabilities, and tax planning strategies. Based upon the Company’s historical operating losses and the uncertainty of future taxable income, the Company has provided a valuation allowance against most of the deferred tax assets as of March 31, 2022 and 2021.
