Income Taxes	INCOME TAXES For the three months ended March 31, 2015 and 2014, the Company recorded income tax provisions of $27.0 million and $32.5 million, respectively. The effective tax rate for the three months ended March 31, 2015 and 2014 was 39.0% and 39.9%, respectively. The decrease in the effective tax rate for the three months ended March 31, 2015 primarily resulted from the recognition of a discrete tax charge in 2014, which accounted for the higher effective tax rate versus the first quarter of 2015. As of March 31, 2015 and December 31, 2014, the Company had $35.8 million and $35.4 million, respectively, of uncertain tax positions excluding interest and penalties, which, if recognized in the future, would affect the annual effective income tax rate. Reductions to uncertain tax positions primarily from the lapse of the applicable statutes of limitations during the next twelve months are estimated to be approximately $10.5 million, not including any potential new additions. Estimated interest costs and penalties, which are classified as part of the provision for income taxes in the Company’s condensed consolidated statements of income, were $0.9 million and $0.6 million for the three months ended March 31, 2015 and 2014, respectively.
