Income Tax Disclosure [Abstract] |
Income Taxes | NOTE 11 - INCOME TAXES Our 2019 estimated annual effective tax rate before discrete items is 12.9%. The estimated annual effective tax rate differs from the U.S. statutory rate of 21.0% primarily due to the deductions for percentage depletion in excess of cost depletion related to U.S. operations. The 2018 estimated annual effective tax rate before discrete items at March 31, 2018 was 0.1%. The rate in the comparable prior-year period was significantly lower due to the reversal of valuation allowance in the same period. For the three months ended March 31, 2019 and 2018, we recorded discrete items that resulted in an income tax benefit of $0.4 million and expense of $15.7 million, respectively. The prior-year period expense of $15.7 million primarily relates to the $14.5 million reduction of the refundable AMT credit recorded in Income tax receivable, non-current in our Statements of Unaudited Condensed Consolidated Financial Position based on the sequestration guidance issued by the Internal Revenue Service during the first quarter of 2018. This position was subsequently reversed by the Internal Revenue Service during the fourth quarter of 2018. The prior-year period expense was a $15.7 million reduction of an asset and did not result in a cash tax outlay.
