Income Tax

 

The determination of the annual effective tax rate is based upon a number of significant estimates and judgments, including the estimated annual pretax income in each tax jurisdiction in which the Company operates and the development of tax planning strategies during the year. In addition, as a global commercial enterprise, the Company’s tax expense can be impacted by changes in tax rates or laws, the finalization of tax audits and reviews and other factors that cannot be predicted with certainty. As such, there can be significant volatility in interim tax provisions.

 

Income tax expense (benefit) was $0.6 million and $(0.1) million for the three months ended March 31, 2023 and 2022, respectively. The effective tax rates for the three months ended March 31, 2023 and 2022 were 48.5% and 2.0%, respectively. The difference between the Company’s effective tax rates in 2023 and 2022 compared to the U.S. statutory tax rate of 21% is primarily due to a Global Intangible Low-Taxed Income (“GILTI”) inclusion to taxable income and changes in valuation allowances associated with the Company’s assessment of the likelihood of the recoverability of deferred tax assets. The Company has valuation allowances against substantially all of its net operating loss carryforwards and tax credit carryforwards.
