Income Tax Disclosure [Abstract]
Income taxes	14. Income taxes For the quarter ended September 30, 2015, the Company’s income tax provision was $221, compared to $145 for the prior year period. For the nine months ended September 30, 2015, the Company’s income tax provision was $312, compared to $745 for the prior year period. The change in the income tax provision for the nine months ended September 30, 2015 is primarily related to a change in the geographical mix of income which decreased taxable non-U.S. earnings before income taxes when compared to the prior year period. If the Company’s current estimates change in future periods, the impact on the deferred tax assets and liabilities may change correspondingly. As of September 30, 2015 and December 31, 2014, the Company maintained a valuation allowance against its net deferred tax assets primarily attributable to operations in the United States, as the realization of such assets was not considered more likely than not. There were no changes to the Company’s unrecognized tax benefits during the nine months ended September 30, 2015. The Company does not expect any significant changes to its unrecognized tax positions during the next twelve months. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. No interest and penalties related to uncertain tax positions were recognized during the nine months ended September 30, 2015.
