See Note 1,Summary of Significant Accounting Policies, “Income Taxes,” for a discussion of the allocation of income or loss related to pass-through entities, which is referred to as the impact of noncontrolling interests in the above table.The Provision for income tax expense in 2011 is less than the federal statutory rate primarily due to: (1) an approximate $28 million benefit associated with a current period net reduction in the valuation allowance and (2) an approximate $18 million net benefit associated with settlements with various taxing authorities including the settlement of federal income tax claims with the Internal Revenue Service for tax years 2007 and 2008 offset by (3) approximately $7 million of net expense primarily related to corrections to 2010 deferred tax assets associated with our NOLs and corresponding valuation allowance. See Note 1,Summary of Significant Accounting Policies, “Out-of-Period Adjustments.”The Provision for income tax benefit in 2010 primarily resulted from the reduction in the valuation allowance, as discussed below. This benefit was offset by settlements related to federal IRS examinations, including reductions in unrecognized tax benefits, as discussed below.Deferred income taxes recognize the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and amounts used for income tax purposes and the impact of available NOLs.

Such losses expire in various amounts at varying times through 2031. Our reported federal NOL as of December 31, 2012 excludes $8.6 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 additional paid-in-capital when they reduce taxes payable.For the years ended December 31, 2012, 2011, and 2010, the net decreases in our valuation allowance were $10.5 million, $62.4 million, and $825.4 million, respectively. Substantially all of the decrease in the valuation allowance in 2012 and 2010 and approximately $21 million of the decrease in the valuation allowance during 2011 related primarily to our determination it is more likely than not a substantial portion of our deferred tax assets will be realized in the future. Based on the weight of available evidence including our generation of pre-tax income from continuing operations on a three-year look back basis, our forecast of future earnings, and our ability to sustain a core level of earnings, we determined, in the fourth quarter of 2010, it is more likely than not a substantial portion of our deferred tax assets will be realized on a federal basis and in certain state jurisdictions in the future and decreased our valuation allowance. In addition, approximately $34 million of the decrease in the valuation allowance in 2011 was due to the corrections made to the valuation allowance, as discussed above. Approximately $7 million of the decrease in the valuation allowance in 2011 resulted from our settlement with the IRS for tax years 2007 and 2008 which enabled us to utilize certain capital losses previously offset by a valuation allowance.As of December 31, 2012, we have a remaining valuation allowance of $39.8 million. This valuation allowance remains recorded due to uncertainties regarding our ability to utilize a portion of our deferred tax assets, primarily related to 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 utilization of NOLs could be subject to limitations under Internal Revenue Code Section 382 (“Section 382”) and may be limited in the event of certain cumulative changes in ownership interests of significant shareholders over a three-year period in excess of 50%. Section 382 imposes an annual limitation on the use of these 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.As of January 1, 2010, total remaining gross unrecognized tax benefits were $50.9 million, all of which would affect our effective tax rate if recognized. Total accrued interest expense related to unrecognized tax benefits was $1.9 million as of January 1, 2010. The amount of unrecognized tax benefits changed during 2010 due to a settlement with the IRS regarding tax positions taken for tax years 2005 through 2007 and the running of the statute of limitations on certain state claims. Total remaining gross unrecognized tax benefits were $12.6 million as of December 31, 2010, all of which would affect our effective tax rate if recognized. Total accrued interest expense related to unrecognized tax benefits as of December 31, 2010 was $1.1 million. The amount of unrecognized tax benefits changed during 2011 primarily due to the settlement of federal income tax claims with the IRS for tax years 2007 and 2008 and the lapse of the applicable statute of limitations for certain federal and state claims. Total remaining gross unrecognized tax benefits were $6.0 million as of December 31, 2011, all of which would affect our effective tax rate if recognized. Total accrued interest expense related to unrecognized tax benefits as of December 31, 2011 was $0.1 million, all of which would affect our effective tax rate if recognized. The amount of unrecognized tax benefits changed during 2012 primarily based on ongoing discussions with taxing authorities as part of our continued pursuit of the maximization of our tax benefits, primarily related to our federal NOL, as discussed below. Total remaining gross unrecognized tax benefits were $78.0 million as of December 31, 2012, $76.0 million 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 PenaltiesJanuary 1, 2010$50.9 $1.9Gross amount of increases in unrecognized tax benefits related to prior periods96.1 0.1Gross amount of decreases in unrecognized tax benefits related to prior periods(37.5) —Decreases in unrecognized tax benefits relating to settlements with taxing authorities(93.0) —Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations(3.9) (0.9)December 31, 201012.6 1.1Gross amount of increases in unrecognized tax benefits related to prior periods19.8 —Gross amount of decreases in unrecognized tax benefits related to prior periods(3.0) —Decreases in unrecognized tax benefits relating to settlements with taxing authorities(20.2) —Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations(3.2) (1.0)December 31, 20116.0 0.1Gross amount of increases in unrecognized tax benefits related to prior periods75.8 —Gross amount of decreases in unrecognized tax benefits related to prior periods(2.5) —Decreases in unrecognized tax benefits relating to settlements with taxing authorities(0.9) —Reductions to unrecognized tax benefits as a result of a lapse of the applicable statute of limitations(0.4) (0.1)December 31, 2012$78.0 $—Our continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. For the years ended December 31, 2012, 2011, and 2010, we recorded $0.7 million, $4.7 million, and $1.7 million of net interest income, respectively, primarily related to amended state income tax returns, as part of our income tax provision. Total net accrued interest income was $0.2 million and $0.1 million as of December 31, 2012 and 2011, respectively.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 2008. We are currently under audit by the IRS for the 2009 and 2010 tax years and by two states for tax years ranging from 2007 through 2011. For the tax years that remain open under the applicable statutes of limitations, amounts related to these unrecognized tax benefits have been considered by management in its estimate of our potential net recovery of prior years’ income taxes. It is reasonably possible a decrease in our unrecognized tax benefits of less than $0.1 million will occur within the next 12 months due to the closing of the applicable statutes of limitations.In addition, we continue to actively pursue, through ongoing discussions with taxing authorities, the maximization of our income tax benefits, primarily related to our federal NOL. As part of our pursuit of these benefits, we requested a pre-filing agreement with the IRS, the primary purpose of which was to consider whether certain amounts related to the restatement of our financial statements for periods prior to 2003 result in net increases to our federal NOL and adjustments to other tax attributes. The pre-filing agreement program permits taxpayers to resolve certain tax issues in advance of filing their corporate income tax returns. Due to the unique nature of our claims and uncertainties around this process, we did not recognize any amounts associated with our request as of December 31, 2012. In July 2012, the IRS granted our request to utilize the pre-filing agreement process. Depending upon the process undertaken by the IRS to audit and settle these matters, the accounting recognition criteria for these positions could be met either in part or in total as the process continues or upon completion of the process. Therefore, as we continue this process with the IRS, it is reasonably possible that over the next twelve-month period we may experience an increase or decrease to our unrecognized tax benefits, our NOLs, other tax attributes, or any combination thereof that could have a material net favorable impact on income tax expense and our effective income tax rate. Due to the aforementioned uncertainties regarding the outcome of this process, it is not possible to determine the range of any impact at this time. |
