Income Taxes	Note 4—Income Taxes The Company estimates its annual effective tax rate based on projected financial income for the full year at the end of each interim reporting period unless projected financial income for the full year is close to break-even, in which case the annual effective tax rate could become volatile and could distort the income tax provision for an interim period. When this happens, the Company calculates the interim income tax provision using actual year-to-date financial results for certain jurisdictions. This method results in an income tax provision based solely on the year-to-date financial taxable income or loss for those jurisdictions. In both cases, the tax effect of unusual or infrequently occurring items, including effects of changes in tax laws or rates, are reported in the interim period in which they occur. For the three months ended March 31, 2013, the Company determined the current period income tax benefit for the Alabama operations using the actual year-to-date financial results as compared to the estimated annual effective tax rate method utilized in 2012. The year-to-date tax benefit for the Canada, U.K. and West Virginia operations was determined using the estimated annual effective tax rate method. The Company recognized an income tax benefit of $66.0 million for the three months ended March 31, 2013, compared to an income tax provision of $8.7 million for the three months ended March 31, 2012 as the Company incurred a pretax operating loss for the three months ended March 31, 2013 compared to pretax operating income for the same period in 2012. The 2013 and 2012 tax rates reflect the benefit of our Canadian and U.K. operations which are taxed at statutory rates lower than the U.S. rate and the effects of tax losses in excess of losses related to foreign financing activities. The effective tax rates also reflect statutory depletion deductions in the Alabama mining operations.
