Income Taxes

The effective tax rate for the three months ended March 31, 2021 and 2020 was 5.0% and 7.1%, respectively. The Company has established valuation allowances on deferred tax assets for losses and tax credits generated in 2021 and 2020.   The effective tax rate for 2021 was negatively impacted by current year losses in certain jurisdictions with no tax benefit, partially offset by favorable adjustments related to utilization of losses and tax credits for prior year tax returns.  The effective tax rate for 2020 was negatively impacted by losses in certain jurisdictions with no tax benefit as well as the impairment of nondeductible goodwill, partially offset by an income tax benefit from the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) that was enacted on March 27, 2020 allowing net operating losses originating in 2018, 2019 or 2020 to be carried back five years.
