Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes Our Provision for income tax expense of $23.5 million and $54.3 million for the three and six months ended June 30, 2019, respectively, primarily resulted from the application of our estimated effective blended federal and state income tax rate, tax benefits resulting from share-based compensation windfalls and the deductibility of the settlement payment discussed in Note 12, Contingencies and Other Commitments. Our Provision for income tax expense of $29.3 million and $59.3 million for the three and six months ended June 30, 2018, respectively, primarily resulted from the application of our estimated effective blended federal and state income tax rate. We have state net operating losses (“NOLs”) of $62.8 million that expire in various amounts at varying times through 2031. The $42.6 million of net deferred tax assets included in the accompanying condensed consolidated balance sheet as of June 30, 2019 reflects management’s assessment it is more likely than not we will be able to generate sufficient future taxable income to utilize those deferred tax assets based on our current estimates and assumptions. As of June 30, 2019, we maintained a valuation allowance of $34.3 million due to uncertainties regarding our ability to utilize a portion of our state NOLs and other credits before they expire. The amount of the valuation allowance has been determined for each tax jurisdiction based on the weight of all available evidence including management’s estimates of taxable income for each jurisdiction in which we operate over the periods in which the related deferred tax assets will be recoverable. It is possible we may be required to increase or decrease our valuation allowance at some future time if our forecast of future earnings varies from actual results on a consolidated basis or in the applicable state tax jurisdictions, if the timing of future tax deductions differs from our expectations, or pursuant to changes in state tax laws and rates. During the third quarter of 2016, we filed a non-automatic tax accounting method change related to billings denied under pre-payment claims reviews conducted by certain of our Medicare Administrative Contractors. In March 2017, the IRS approved our request resulting in additional cash tax benefits of approximately $51.3 million through December 31, 2017. These benefits are expected to reverse as pre-payment claims denials are settled and collected. This change did not have a material impact on our effective tax rate. The 2017 Tax Cuts and Jobs Act (the “Tax Act”) included revisions to Internal Revenue Code §451 that may eliminate this deferral of revenue for tax purposes. We are currently evaluating this provision of the Tax Act and its future impact on the method change we received in March 2017. Total remaining gross unrecognized tax benefits were $0.6 million and $0.9 million as of June 30, 2019 and December 31, 2018, respectively, all of which would affect our effective tax rate if recognized. Our continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. Interest recorded as part of our income tax provision during the three and six months ended June 30, 2019 and 2018 was not material. Accrued interest income related to income taxes as of June 30, 2019 and December 31, 2018 was not material. In December 2016, we signed an agreement with the IRS to participate in their Compliance Assurance Process (“CAP”) for the 2017 tax year. CAP is a program in which we and the IRS endeavor to agree on the treatment of significant tax positions prior to the filing of our federal income tax returns. We renewed this agreement in January 2018 for the 2018 tax year and in December 2018 for the 2019 tax year. As a result of these agreements, the IRS is currently examining the 2018 and 2019 tax years. In July 2019, the IRS issued a no-change Letter effectively closing our 2017 tax year audit. The statute of limitations has expired or we have settled federal income tax examinations with the IRS for all tax years through 2017. Our state income tax returns are also periodically examined by various regulatory taxing authorities. We are currently under audit by one state for tax years ranging from 2013 through 2015. For the tax years that remain open under the applicable statutes of limitation, amounts related to unrecognized tax benefits have been considered by management in its estimate of our potential net recovery of prior years’ income taxes. Based on discussions with taxing authorities, we anticipate that approximately $0.2 million of our unrecognized tax benefits will be released within the next 12 months.
