The Company is subject to federal and state income taxes in the United States. The Company’s tax provision for interim periods is determined using an estimate of its annual effective tax rate, adjusted for discrete items arising in that quarter, unless a reliable estimate of ordinary income or the related tax expense or benefit cannot be made. In each quarter, the Company updates its estimate of the annual effective tax rate, and if its estimated annual tax rate changes, the Company makes a cumulative adjustment in that quarter. For the three months ended March 31, 2022, the Company concluded that it was in a cumulative loss and maintained the valuation allowance.

For the three months ended March 31, 2022 and 2021, the Company's effective income tax rate was 0.8% and 9.5%, respectively, differing from the U.S. corporate statutory federal income tax rate of 21%, and the difference is primarily the result of the valuation allowance applied to reduce the Company’s deferred tax assets to the amount that is more likely than not to be realized.

As of March 31, 2022 the Company had unrecognized tax benefits of $0.7 million. The tax returns for years 2018-2022 may be selected for examination by taxing authorities.
