| Income Taxes                         | Income TaxesOur Provision for income tax expense of $32.8 million and $33.5 million for the three months ended March 31, 2014 and March 31, 2013, respectively, primarily resulted from the application of our estimated effective blended federal and state income tax rate. We have significant federal and state net operating loss carryforwards (“NOLs”) that expire in various amounts at varying times through 2031. Our utilization of NOLs could be subject to limitations under Internal Revenue Code Section 382 (“Section 382”) and may be limited in the event certain cumulative changes in ownership interests of significant stockholders over a three-year period exceed 50%. Section 382 imposes an annual limitation on the use of certain carryforward losses to an amount that approximates the value of a company at the time of an ownership change multiplied by the long-term tax exempt rate. At this time, we do not believe these limitations will restrict our ability to use any NOLs before they expire. However, no such assurances can be provided.The $464.2 million of net deferred tax assets included in the accompanying condensed consolidated balance sheet as of March 31, 2014 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 March 31, 2014, we maintained a valuation allowance of $30.3 million due to uncertainties regarding our ability to utilize a portion of our state NOLs 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, or if the timing of future tax deductions differs from our expectations.Our reported federal NOL of $303.0 million (approximately $866 million on a gross basis) as of March 31, 2014 excludes $11.2 million related to operating loss carryforwards resulting from excess tax benefits related to share-based awards, the tax benefits of which, when recognized, will be accounted for as a credit to Capital in excess of par value when they reduce taxes payable.Total remaining gross unrecognized tax benefits were $1.1 million as of March 31, 2014 and December 31, 2013, none of which would affect our effective tax rate if recognized. A reconciliation of the beginning and ending liability for unrecognized tax benefits is as follows (in millions): Gross Unrecognized Income Tax Benefits Accrued Interest and PenaltiesBalance at December 31, 2013$1.1 $0.3Gross amount of increases in unrecognized tax benefits related to prior periods— 0.1Balance at March 31, 2014$1.1 $0.4Our 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 months ended March 31, 2014 and 2013 was not material. Accrued interest income related to income taxes as of March 31, 2014 and December 31, 2013 was not material.HealthSouth and its subsidiaries’ federal and state income tax returns are periodically examined by various regulatory taxing authorities. In connection with such examinations, we have settled federal income tax examinations with the IRS for all tax years through 2010. We are currently under audit by two states for tax years ranging from 2007 through 2011.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. We do not expect a material change in our unrecognized tax benefits within the next 12 months due to the closing of the applicable statutes of limitation. |
