Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our effective tax rate for the three and six months ended June 30, 2019 was (62.8)% and 0.8%, respectively, compared to 41.9% and 92.6%, respectively for the three and six months ended June 30, 2018. The significant items impacting the 2019 rates include a benefit recognized due to application of the exception to the rules regarding intraperiod tax allocation, a provision for net state and foreign taxes, certain permanent items, and a change in the valuation allowance established for the net deferred tax asset balance projected for December 31, 2019. The significant items impacting the 2018 rates include a provision for net state and foreign taxes, foreign withholding taxes related to dividends from a foreign subsidiary, certain permanent items, and a change in the valuation allowance established for the net deferred tax asset balance that had been projected for December 31, 2018. We recognize valuation allowances on deferred tax assets if, based on the weight of the evidence, we determine it is more likely than not such assets will not be realized. Changes in valuation allowances are included in our tax provision in the period of change. In determining whether a valuation allowance is warranted, we evaluate factors such as prior years’ earnings history, expected future earnings, loss carry-forward periods, reversals of existing deferred tax liabilities and tax planning strategies that potentially enhance the likelihood of the realization of a deferred tax asset. At June 30, 2019 and December 31, 2018, substantially all of our net deferred tax assets were subject to a valuation allowance.
