Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective December 31, 2015, the Company early-adopted ASU No. 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes, which changes how deferred taxes are classified on the balance sheet. The ASU eliminates the current requirement for organizations to present deferred tax liabilities and assets as current and noncurrent in a classified balance sheet. Instead, organizations will be required to classify all deferred tax assets and liabilities as noncurrent. The provisions have been applied on a prospective basis and prior periods were not retrospectively adjusted, as permitted by the ASU. For the three and six months ended June 30, 2016, the Company recorded an income tax expense of $0.1 million and $0.8 million, respectively, primarily related to ordinary tax expense of the Company’s foreign subsidiaries and the tax effect of items in accumulated other comprehensive loss, net. For the three and six months ended June 30, 2015, the Company recorded an income tax expense of $1.3 million and $0.8 million, respectively, comprised primarily of ordinary foreign tax expense of the Company’s foreign subsidiaries, partially offset by the tax effect of items in accumulated other comprehensive loss, net. The Company’s effective tax rate for the three and six months ended June 30, 2016 and 2015 differs from the statutory federal income tax rate of 34%, primarily due to the impact of operations in foreign jurisdictions, as well as income or loss in the United States federal and state jurisdictions for which no tax expense or benefit is recorded. There is a difference in the effective tax rate for the three and six months ended June 30, 2016, compared to the three and six months ended June 30, 2015, which is primarily due to levels of losses in the United States for which no income tax benefit was recorded in relation to income generated in foreign jurisdictions. The Company utilizes the liability method of accounting for income taxes. Under the liability method, deferred taxes are determined based on the temporary differences between the financial statement and tax bases of assets and liabilities using enacted tax rates. The Company’s position is to record a valuation allowance when it is more likely than not that some of the deferred tax assets will not be realized. Based on all available objective evidence, the Company believes that it is more likely than not that the net United States deferred tax assets will not be fully realized. Accordingly, the Company continues to maintain a full valuation allowance on its United States deferred tax assets and will do so until there is sufficient evidence to support the reversal of all or some portion of this valuation allowance. The Company or one of its subsidiaries files income tax returns in the United States federal jurisdiction and various state and foreign jurisdictions. The Company’s United States and state income tax return years 1996 through 2015 remain open to examination. In addition, the Company files tax returns in multiple foreign taxing jurisdictions with open tax years ranging from 2010 to 2015. The Company anticipates that the total unrecognized tax benefits will not significantly change within the next 12 months due to the settlement of audits and the expiration of statutes of limitations. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. For the three and six months ended June 30, 2016 and 2015, the Company did not recognize any significant interest or penalties related to uncertain tax positions, nor had any been accrued for as of June 30, 2016 and December 31, 2015.
