Income Tax Disclosure [Abstract]
Income taxes	13. Income taxes The Company recognized a $7.7 million and $10.3 million provision for income tax which reflects an effective tax rate of 39.5% and 36.3% on pre-tax income for the six months ended June 30, 2013 and 2012, respectively. For the six months ended June 30, 2012, $0.4 million of income related to legal settlements is discrete and not included in the foregoing calculation of the effective tax rate. Excluding the impact of various discrete charges, the effective tax rate on continuing operations for the first six months of 2013 and 2012 was 39.5% and 40.3%, respectively. The principal factors affecting the Company’s effective tax rate was the Company’s mix of earnings among various tax jurisdictions, state taxes and current period losses in certain jurisdictions for which the Company does not currently provide a tax benefit. The company applies a more likely than not recognition threshold for all tax uncertainties. Accounting guidance only allows the recognition of those tax benefits that have a greater than 50% likelihood of being sustained upon examination by the taxing authorities. As of June 30, 2013 and December 31, 2012, the Company’s unrecognized tax benefit was $0.8 million and $1.2 million, respectively. In March 2013 the Company settled a $0.9 million liability that had been previously accrued as of December 31, 2012. The entire amount of unrecognized tax benefits, including interest, would favorably impact the Company’s effective tax rate if recognized. As of June 30, 2013, the Company does not expect the amount of unrecognized tax benefits to change significantly over the next twelve months. Unremitted foreign earnings increased from $285.3 million at December 31, 2011 to $292 million at December 31, 2012. The $292 million includes $293.8 million in U.S subsidiaries. The Company does not anticipate any impact on income tax liabilities since earnings are permanently reinvested for both U.S and non-U.S. subsidiaries.
