Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Upon evaluation of all available evidence, and considering the projected U.S. pre-tax losses for 2017, a valuation allowance has been contemplated as a component of the estimated annual effective tax rate for 2017. The valuation allowance to be recorded during 2017 related to the U.S. federal tax jurisdiction is incremental to the valuation allowance recorded as of December 31, 2016. The Company maintained other valuation allowances for certain non-U.S. jurisdictions with cumulative losses. The effective income tax rates for the three months ended March 31, 2017 and 2016 were (19.9)% and 17.2%, respectively, and were determined using an estimated annual effective tax rate after considering any discrete items for such periods. The change in the effective tax rates relates primarily to an increase in the valuation allowance recorded against net deferred tax assets in the U.S. federal tax jurisdiction for the three months ended March 31, 2017. The effective income tax rate for the three months ended March 31, 2017 reflects an overall tax expense due to the application of a full valuation allowance against the U.S. pre-tax losses coupled with a tax expense on foreign pre-tax earnings. In the three months ended March 31, 2016, we have an overall tax benefit as the valuation allowance recorded during the period was only applicable to a portion of the U.S. pre-tax losses.

As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Upon evaluation of all available evidence, and considering the projected U.S. pre-tax losses for 2017, a valuation allowance has been contemplated as a component of the estimated annual effective tax rate for 2017. The valuation allowance to be recorded during 2017 related to the U.S. federal tax jurisdiction is incremental to the valuation allowance recorded as of December 31, 2016. The Company maintained other valuation allowances for certain non-U.S. jurisdictions with cumulative losses.

The effective income tax rates for the three months ended March 31, 2017 and 2016 were (19.9)% and 17.2%, respectively, and were determined using an estimated annual effective tax rate after considering any discrete items for such periods.
