Mar. 31, 2014
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company's effective tax rate was 38.2% for the three months ended March 31, 2014 as compared to 39.6% for the three months ended March 31, 2013. The effective tax rate in 2014 was lower compared to the same period of 2013 due to the tax provision in 2013 reflecting a higher amount of unrecognized tax benefits as a result of audits from taxing authorities. The total gross unrecognized tax benefit as of March 31, 2014 and December 31, 2013 was $2.8 million and $2.7 million, respectively, excluding interest, penalties and related tax benefits. The Company estimates the unrecognized tax benefit may decrease over the upcoming 12 months by an amount up to $0.9 million related to settlements with taxing authorities and the lapse of statutes of limitations. For the remaining liability, due to the uncertainties related to these tax matters, the Company is unable to make a reasonably reliable estimate when cash settlement with a taxing authority will occur. As of March 31, 2014, accrued interest was $3.1 million and accrued penalties were less than $0.1 million, excluding any related income tax benefits. As of December 31, 2013, accrued interest and penalties were $2.9 million and $0.1 million, respectively, excluding any related income tax benefits. The increase of $0.2 million of accrued interest is primarily related to an increase in unrecognized tax benefits as a result of recent audits by taxing authorities. The Company recognizes interest accrued related to unrecognized tax benefits and penalties as a component of its income tax provision recognized in the Consolidated Statements of Comprehensive Income. The Company files federal income tax returns and the Company or one of its subsidiaries files income tax returns in various state and foreign jurisdictions. With few exceptions, the Company is no longer subject to federal, state or non-United States tax examinations by tax authorities for years before 2008. In the second quarter of 2013, the Internal Revenue Service (“IRS”) issued a Revenue Agent’s Report (“RAR”) related to its examination of the Company’s U.S federal income tax return for the tax years 2008 to 2010. The Company disagrees with a portion of the proposed assessments and has contested them through the IRS administrative appeals procedures. We anticipate the appeals process to continue into 2014. The Company believes that adequate reserves have been provided relating to all matters contained in the tax periods open to examination.
