NOTE 14 - INCOME TAXES
Our 2013 estimated annual effective tax rate before discrete items is approximately 1.4 percent. This estimated 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, income not subject to tax and foreign taxes and benefits derived from operations outside the U.S., which are taxed at rates lower than the U.S. statutory rate of 35 percent. There were discrete items booked in the first quarter of approximately $7.7 million primarily related to adjustments to deferred tax balances, including the reversal of a previously recorded valuation allowance for which it was determined the benefit of the associated deferred tax asset is realizable.
