Income Taxes	6 Months Ended
Jun. 30, 2017
Income Tax Disclosure [Abstract]
Income Tax Disclosure	Income Taxes The Company's effective tax rate for the three months ended June 30, 2017 differs from the statutory rate due to a full valuation allowance provided against its United States (“U.S.”) net deferred tax assets, and taxes on foreign income that differ from the U.S. tax rate. The Company utilizes the asset and liability method of accounting for income taxes. The Company records deferred tax assets to the extent it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance. Based upon the Company's review of all positive and negative evidence, including its three year U.S. cumulative pre-tax book loss and taxable loss, it concluded that a full and a partial valuation allowance should continue to be recorded against its U.S. and Canadian net deferred tax assets at June 30, 2017. In certain other foreign jurisdictions, where the Company does not have cumulative losses or other negative evidence, the Company had net deferred tax assets of $1.0 million and $1.1 million at June 30, 2017 and December 31, 2016. In the future, if the Company determines that it is more likely than not that it will realize its U.S. and Canadian net deferred tax assets, it will reverse the applicable portion of the valuation allowance and recognize an income tax benefit in the period in which such determination is made. The ending balance for the unrecognized tax benefits for uncertain tax positions was approximately $3.5 million at June 30, 2017. The related interest and penalties were $0.8 million and $0.2 million. The uncertain tax positions that are reasonably possible to decrease in the next twelve months are insignificant. The Company is currently under tax examination in India. The periods covered under examination are the Company's financial years 2005, 2006, 2008 and 2011. The examinations are in various stages of appellate proceedings and all material uncertain tax positions associated with the examination have been taken into account in the ending balance of the unrecognized tax benefits at June 30, 2017. The Company is currently under tax examination in Canada. The periods covered under examination in Canada are the Company's financial years 2013, 2014, 2015 and 2016. No examination adjustments have been proposed. As of June 30, 2017, the Company is not under examination by tax authorities in any other jurisdictions.
