Income Taxes	Income Taxes On a quarterly basis, the Company estimates the effective tax rate expected to be applicable for the full year and makes changes if necessary based on new information or events. The estimated annual effective tax rate is forecast based on actual historical information and forward-looking estimates and is used to provide for income taxes in interim reporting periods. The Company also recognizes the tax impact of certain unusual or infrequently occurring items, such as the effects of changes in tax laws or rates and impacts from settlements with tax authorities, discretely in the quarter in which they occur. Additionally, the annual effective tax rate differs from the statutory U.S. Federal tax rate of 35% primarily due to the impact of state income taxes and to benefits related to the domestic production activities deduction. For the three months ended June 30, 2016, the Company recorded income tax expense of $7.7 million at an effective tax rate of 33.2%, which varied from the U.S. Federal tax rate of 35% primarily due to a 1.9% tax benefit related to the domestic production activities deduction and a 1.7% tax benefit attributable to the accounting for the investment in a foreign affiliate. For the three months ended June 30, 2015, the Company recorded income tax expense of $18.0 million at an effective tax rate of 35.7%. For the six months ended June 30, 2016, the Company recorded income tax expense of $0.4 million at an effective tax rate of 189.6%, which varied from the U.S. Federal tax rate of 35% primarily due to a 174.7% discrete tax charge related to state income taxes. For the six months ended June 30, 2015, the Company recorded income tax expense of $19.1 million at an effective tax rate of 34.4%. There have been no material changes to the balance of unrecognized tax benefits reported at December 31, 2015. During the quarter ended March 31, 2016, the IRS completed its audit of the Company’s 2011 and 2012 consolidated Federal income tax returns. The results of the examination will not have a material effect on the Company’s 2016 effective tax rate.
