Income Tax Disclosure [Abstract]
Income Taxes	7. Income Taxes We are calculating our effective income tax rate using an estimated annual effective tax rate with the exception of jurisdictions where losses have a full valuation allowance against them and jurisdictions with indefinite lived deferred tax liabilities for which their deferred tax assets are also subject to a full valuation allowance. In assessing the realizability of the deferred tax assets, management considers whether it is more likely than not that some portion or the entire deferred tax assets will not be realized. The ultimate realization of the deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. Due to the continued pre-tax operating losses reported through the first quarter of 2019, management has not changed its valuation allowance position as of March 31, 2019 from December 31, 2018. Our income tax expense differs from the statutory federal tax rate of 21% and related statutory state tax rates primarily due to the tax amortization on certain indefinite-lived intangible assets that do not have any valuation allowance, offset by the deferred tax asset created from disallowed interest as a result of tax laws changes from the Tax Legislation, and other changes in the valuation allowance. U.S. Federal jurisdiction and the jurisdictions of Florida, New York, California, Illinois, Texas and Puerto Rico are the major tax jurisdictions where we file income tax returns. The tax years that remain subject to assessment of additional liabilities by the federal, state and local tax authorities are 2015 through 2018. The tax years that remain subject to assessment of additional liabilities by the Puerto Rico tax authority are 2012 through 2018. Based on our evaluation, we have concluded that there are no material uncertain tax positions requiring recognition in our consolidated financial statements as of March 31, 2019 and December 31, 2018.
