Income Taxes	12.Income Taxes Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. We evaluate the recoverability of our deferred tax assets by scheduling the expected reversals of deferred tax assets and liabilities in order to determine whether net operating loss carry forwards are recoverable prior to expiration and have established a valuation allowance in accordance with ASC Topic 740, “Income Taxes”. The tax expense for the three and nine months ended September 30, 2018 primarily relates to state income taxes and tax amortization of indefinite-life intangibles. The expected tax expense from operating income during the three and nine months ended September 30, 2018 was offset by the reduction of our valuation allowance. In future reporting periods, we will continue to assess the likelihood that deferred tax assets will be realizable. In connection with our initial analysis of the impact of the Tax Cuts and Jobs Act, we recorded a provisional income tax benefit of approximately $18.3 million at December 31, 2017 for the revaluation of our net deferred tax liability. There were no changes recorded in the third quarter of 2018 to the provisional income tax benefit. At September 30, 2018, the Company had available unused federal net operating loss carryforwards of approximately $167.6 million. The net operating loss carryforwards will expire at various dates from 2019 through 2038.
