Income Tax Disclosure [Abstract] |
Income Taxes | NOTE 9 - INCOME TAXES Our 2016 estimated annual effective tax rate before discrete items is approximately 0.4 percent. The annual effective tax rate differs from the U.S. statutory rate of 35 percent primarily due to deductions for percentage depletion in excess of cost depletion related to U.S. operations, a deduction for worthless stock and the placement of valuation allowance from operations in the current year. The 2015 estimated annual effective tax rate before discrete items at September 30, 2015 was 2.1 percent. For the three and nine months ended September 30, 2016, we recorded discrete items that resulted in an income tax benefit of $2.9 million and $2.2 million, respectively. These items relate primarily to prior year adjustments due to a change in estimate of the 2015 net operating loss and corresponding reversal of valuation allowance and quarterly interest accrued on reserves for uncertain tax positions. For the three and nine months ended September 30, 2015, there were discrete items that resulted in an income tax benefit of $4.5 million and income tax expense of $162.6 million, respectively. These items were related primarily to the recording of valuation allowances against existing deferred tax assets as a result of the determination that these would no longer be realizable.
