Income Taxes	(8) Income Taxes The income tax provision was $9.7 million and $18.8 million for the three and six months ended June 30, 2013, respectively, compared to income tax benefit of $15.3 million and $10.5 million for the same periods in 2012. The effective income tax rate was 38.5% and 38.3% for the three and six months ended June 30, 2013, respectively, as compared to 4.2% and 2.9% for the same periods in 2012. The increase in the effective tax rate for the three and six months ended June 30, 2013, as compared to the same periods in 2012, was primarily due to the $376.6 million impairment charge in the second quarter of 2012 and discrete events. The income tax expense for the three and six months ended June 30, 2013 of $9.7 million and $18.8 million, respectively, includes discrete items of less than $0.1 million and ($0.4) million, related mainly to a favorable state audit settlement and an adjustment to state tax attributes, compared to no discrete items for the second quarter of 2012 and $3.6 million for the first six months of 2012, related mainly to stock based compensation items. As of June 30, 2013, the total amount of unrecognized tax benefits, including related interest and penalties was $4.1 million. If the total amount of unrecognized tax benefits was recognized, $3.9 million of unrecognized tax benefits and $0.2 million of interest would impact the effective tax rate. The Company believes that it is reasonably possible that the amount of unrecognized tax benefits could decrease by less than $0.1 million within the next twelve months due to the settlement of audits or the expiration of the statute of limitations in various jurisdictions. The Company’s 2010 U.S. Federal tax return is currently being audited by the Internal Revenue Service. The Company currently does not expect any material adjustments to arise from this audit.
