Mar. 31, 2019
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense was $0.1 million, or an effective income tax rate of 30.6%, for the three months ended March 31, 2019 compared to $1.7 million, or an effective income tax rate of 39.7%, for the three months ended March 31, 2018. The decrease in the effective income tax rate in 2019 compared to 2018 is primarily due to a $0.9 million increase to the provisional estimate recorded in the first quarter of 2018 relating to the one-time transition tax on the mandatory deemed repatriation of cumulative foreign earnings, imposed by the Tax Cuts and Jobs Act (the "Tax Act") that was enacted on December 22, 2017. Income tax expense for the interim quarterly periods is based on an estimated annual effective tax rate which includes the U.S. federal, state and local, and non-U.S. statutory rates, permanent differences, and other items that may have an impact on income tax expense. An uncertain tax position taken or expected to be taken in a tax return is recognized in the financial statements when it is more likely than not (i.e., a likelihood of more than fifty percent) that the position would be sustained upon examination by tax authorities that have full knowledge of all relevant information. A recognized tax position is then measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Interest and penalties related to income taxes are accounted for as income tax expense. As of March 31, 2019, we had no uncertain tax positions reflected on our condensed consolidated balance sheet. The Company files income tax returns in U.S. federal, state and local jurisdictions, and various non-U.S. jurisdictions, and is subject to audit by tax authorities in those jurisdictions. Tax years 2015 through 2018 remain open to examination by these tax jurisdictions, and earlier years remain open to examination in certain of these jurisdictions which have longer statutes of limitations.
