Income Tax Disclosure [Abstract] |
Income taxes | Income taxes We recorded an income tax benefit of $1.0 million for the three months ended March 31, 2018 and an income tax benefit of $0.3 million for the three months ended March 31, 2017 which primarily consisted of tax benefits on losses from foreign operations. Our income tax benefit or expense is based on an annual effective tax rate forecast, including estimates and assumptions that could change during the year. The application of the accounting requirements for income taxes in interim periods, after consideration of our valuation allowance, causes a significant variation in the typical relationship between income tax expense/benefit and pretax accounting income/loss. As of March 31, 2018, all of Century's U.S. and certain foreign deferred tax assets, net of deferred tax liabilities, continue to be subject to a valuation allowance. We continue to assess the impact of the recently enacted Tax Cuts and Jobs Act (the “Act”) on our business and our consolidated financial statements through the measurement period allowed under Staff Accounting Bulletin ("SAB") 118. Adjustments to provisional amounts, if any, that are identified during the measurement period will be recorded in the reporting period in which the adjustment is determined. As of March 31, 2018, no adjustments have been recorded to the recorded provisional amounts related to the Act. On April 2, 2018, the Internal Revenue Service issued Notice 2018-26 which provides guidance on how to determine, report and pay the repatriation tax on deemed repatriated earnings of foreign subsidiaries provided in the Tax Reform Act and included in the consolidated financial statements for the year ended December 31, 2017. Notice 2018-26 is not expected to have a significant impact on the Company's consolidated financial statements.
