Income Tax Disclosure [Abstract] |
Income taxes | Income taxes We recorded an income tax benefit for the three months ended March 31, 2014 of $1,094, which primarily consisted of foreign and state income taxes. Our domestic deferred tax assets, net of deferred tax liabilities, are subject to a valuation allowance; therefore, the domestic losses were not benefited. We recorded income tax expense for the three months ended March 31, 2013 of $2,517, which primarily consisted of foreign and state income taxes. 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 requirements for accounting for income taxes in interim periods, after consideration of our valuation allowance, causes a significant variation in the typical relationship between income tax expense and pretax accounting income. For the first quarter of 2014, the application of our effective tax rate resulted in a benefit primarily due to not recognizing the benefit of current period losses in certain domestic jurisdictions where it is not more likely than not that such benefits would be realized. As of March 31, 2014, 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. The realization of these assets is dependent on substantial future taxable income which, at March 31, 2014, is not more likely than not to be achieved. Our Icelandic tax returns are subject to examination beginning with the 2008 tax year. Our 2010 through 2012 tax years are currently under review by the Directorate of Internal Revenue of Iceland.
