Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes We file a consolidated federal income tax return, consolidated unitary tax returns in certain states and other separate state income tax returns for our subsidiary companies. The income tax provision for interim periods is generally determined based upon the expected effective income tax rate for the full year and the tax rate applicable to certain discrete transactions in the interim period. To determine the annual effective income tax rate, we must estimate both the total income (loss) before income tax for the full year and the jurisdictions in which that income (loss) is subject to tax. The actual effective income tax rate for the full year may differ from these estimates if income (loss) before income tax is greater than or less than what was estimated or if the allocation of income (loss) to jurisdictions in which it is taxed is different from the estimated allocations. We review and adjust our estimated effective income tax rate for the full year each quarter based upon our most recent estimates of income (loss) before income tax for the full year and the jurisdictions in which we expect that income will be taxed. The effective income tax rate for the three months ended March 31, 2019 and 2018 was 39% and 19%, respectively. Other differences between our effective income tax rate and the U.S. federal statutory rate are the impact of state taxes, foreign taxes, non-deductible expenses, changes in reserves for uncertain tax positions and excess tax benefits or expense on share-based compensation ($0.6 million benefit and $0.7 million expense in 2019 and 2018, respectively). Deferred tax assets totaled $9.9 million at March 31, 2019, which includes the tax effect of state net operating loss carryforwards. We recognize state net operating loss carryforwards as deferred tax assets, subject to valuation allowances. At each balance sheet date, we estimate the amount of carryforwards that are not expected to be used prior to expiration of the carryforward period. The tax effect of the carryforwards that are not expected to be used prior to their expiration is included in the valuation allowance.
