Income Taxes [Abstract]
Income Taxes	(13) Income Taxes For interim tax reporting we estimate our annual effective tax rate and apply it to our year to date ordinary (loss) income. Tax jurisdictions with a projected or year to date loss for which a benefit cannot be realized are excluded. For the three months ended March 31, 2021, income tax expense of $419 was attributable to the mix of earnings among tax jurisdictions as well as tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions. The effective tax rate of 76.2% is greater than the statutory rate primarily due to the impact of tax losses for which no benefit is recognized due to valuation allowances in certain jurisdictions, offset by tax deductible stock compensation and tax incentives. For the three months ended March 31, 2020, income tax expense of $1,213 was primarily related to the mix of earnings among tax jurisdictions. The effective tax rate of 25.8% is greater than the statutory rate primarily due to losses incurred in jurisdictions for which a valuation allowance is recorded.
