Income Tax Disclosure [Abstract]
Income taxes	13. Income taxes The Company recognized a $4.5 million and $7.6 million provision for income tax which reflects an effective tax rate of 77.3% and 48.9% on pre-tax income for the six months ended June 30, 2014, and 2013, respectively. Excluding the impact of various discrete charges, the effective tax rate on continuing operations for the first six months of 2014 and 2013 was 63.2% and 48.8%, respectively. The principal factors affecting the Company’s June 30, 2014, effective tax rate were the Company’s mix of earnings among various tax jurisdictions, state taxes, current period losses in certain jurisdictions for which the Company does not currently provide a tax benefit and variations in the customary relationship between income tax expense and pretax earnings resulting from non-recurring expenses. As of June 30, 2014 and December 31, 2013, the Company’s unrecognized tax benefit was $0.8 million. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits in income tax expense. The Company had approximately $0.5 million accrued for payment of interest and penalties as of June 30, 2014, and December 31, 2013. The entire amount of unrecognized tax benefits, including interest, would favorably impact the Company’s effective tax rate if recognized. It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions will significantly increase or decrease within the next 12 months. These changes may be the result of settlements of ongoing audits, competent authority proceedings or other events. At this time, an estimate of the range of the reasonably possible outcomes cannot be made.
