Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Income tax expense was $5.2 million, or an effective income tax rate of 28.3%, for the nine months ended September 30, 2017 compared to $8.1 million, or an effective income tax rate of 37.4%, for the nine months ended September 30, 2016. The decrease in the effective income tax rate in 2017 compared to 2016 is primarily due to a change in the mix of taxable income from higher taxing jurisdictions to lower taxing jurisdictions. Income tax expense for the 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 September 30, 2017, we had no uncertain tax positions reflected on our 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 2013 through 2016 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.
