Income Tax Disclosure [Abstract] | |
Income taxes | Income Taxes In determining quarterly provisions for income taxes, the Company uses the annual estimated effective tax rate applied to the actual year-to-date loss. The Company’s annual estimated effective tax rate differs from the statutory rate primarily as a result of state taxes, tax amortization of goodwill and changes in the Company’s valuation allowance. The Company recorded $0.2 million and $0.1 million income tax expense for the three months ended June 30, 2016 and 2015, respectively. The Company recorded $0.3 million in income tax expense for each of the six months ended June 30, 2016 and 2015. There were no material changes to the Company’s unrecognized tax benefits in the three and six months ended June 30, 2016, and the Company does not expect to have any significant changes to unrecognized tax benefits through the end of the fiscal year. Due to the presence of net operating loss carryforwards, all income tax years remain open for examination by the Internal Revenue Service (“IRS") and various state taxing authorities. |
