Income Taxes
The income tax expense for the three months ended March 31, 2020 was determined based upon estimates of the Company’s effective income tax rates in various jurisdictions. The difference between the Company’s effective income tax rate and the U.S. federal statutory rate is primarily attributable to state income taxes, foreign income taxes, the effect of certain permanent differences, and full valuation allowance against net deferred tax assets.
The income tax expense for the three months ended March 31, 2020 relates primarily to state minimum income tax and income tax on the Company’s earnings in foreign jurisdictions. The income tax expense for the three months ended March 31, 2019 relates primarily to state minimum income tax.
