| Business Combinations                | Business Combinations:Encompass AcquisitionOn December 31, 2014, we completed the acquisition of EHHI and its Encompass Home Health and Hospice business. Encompass provides home health and hospice services out of 135 locations across 12 states. In the acquisition, we acquired all of the issued and outstanding equity interests of EHHI, other than equity interests contributed to HealthSouth Home Health Holdings, Inc. (“Holdings”), a subsidiary of HealthSouth and now indirect parent of EHHI, by certain sellers in exchange for shares of common stock of Holdings. These certain sellers, who are members of Encompass management, including April Anthony, the Chief Executive Officer of Encompass, contributed a portion of their shares of common stock of EHHI, valued at approximately $64.5 million, in exchange for shares of common stock of Holdings. As a result of that contribution, they hold approximately 16.7% of the outstanding common stock of Holdings, while HealthSouth owns the remainder. In addition, Ms. Anthony and certain other employees of Encompass entered into amended and restated employment agreements, each agreement having an initial term of three years. We funded the cash purchase price in the acquisition entirely with draws under the revolving and expanded term loan facilities of our credit agreement. See Note 8,Long-term Debt.This acquisition was made to enhance our position and expand our ability to provide post-acute healthcare services to patients. We expect approximately 23% of the goodwill resulting from this transaction to be deductible for federal income tax purposes. The goodwill reflects our expectations of favorable growth opportunities in the home health and hospice markets based on positive demographic trends.We accounted for this transaction under the acquisition method of accounting. Because the acquisition took place on December 31, 2014, our consolidated results of operations do not include any results of operations from Encompass. Assets acquired, liabilities assumed, and redeemable noncontrolling interests were recorded at their estimated fair values as of the acquisition date. Estimated fair values were based on various valuation methodologies including: replacement cost and continued use methods for property and equipment; an income approach using primarily discounted cash flow techniques for amortizable intangible assets; an income approach utilizing the relief-from-royalty method for the indefinite-lived intangible asset; and an estimated realizable value approach using historical trends and other relevant information for accounts receivable and certain accrued liabilities. For all other assets and liabilities, the fair value was assumed to represent carrying value due to their short maturities. The excess of the fair value of the consideration conveyed over the fair value of the net assets acquired was recorded as goodwill.The fair values recorded were based upon a preliminary valuation. Estimates and assumptions used in such valuation are subject to change, which could be significant, within the measurement period (up to one year from the acquisition date). The primary areas of the preliminary valuation that are not yet finalized relate to the fair values of amounts for income taxes, adjustments to working capital, and the final amount of residual goodwill. We expect to continue to obtain information to assist us in determining the fair values of the net assets acquired at the acquisition date during the measurement period.The preliminary fair value of the assets acquired and liabilities assumed at the acquisition date were as follows (in millions):Cash and cash equivalents$20.9Accounts receivable, net37.6Prepaid expenses and other current assets8.6Property and equipment, net9.6Identifiable intangible assets: Noncompete agreements (useful life of 2 to 5 years)5.6Trade name (indefinite life)135.2Licenses (useful life of 10 years)58.2Internal-use software (useful life of 3 years)3.2Goodwill592.5Other long-term assets2.1Total assets acquired873.5Current portion of long-term debt2.0Accounts payable0.9Accrued payroll25.8Other current liabilities18.5Long-term debt, net of current portion2.0Deferred tax liabilities64.3Total liabilities assumed113.5Redeemable noncontrolling interests64.5Net assets acquired$695.5Because the noncontrolling interests included in this acquisition include redemption features that are not solely within our control, they are included in Redeemable noncontrolling interests in our consolidated balance sheet as of December 31, 2014. Beginning in the first quarter of 2015, the fair value of the Redeemable noncontrolling interests related to Encompass will be determined using the product of a twelve-month specified performance measure for Holdings and a specified median market price multiple based on a basket of public home health companies. See Note 11,Redeemable Noncontrolling Interests.In conjunction with this acquisition, we granted stock appreciation rights (“SARs”) based on Holdings’ common stock to certain members of Encompass management at closing on December 31, 2014. We granted 122,976 SARs that vest based on continued employment and an additional 129,124 SARs that vest based on continued employment and the extent of Encompass’ attainment of a target 2017 specified performance measure. In general terms, half of the SARs of each type will vest on December 31, 2018 with the remainder vesting on December 31, 2019. The SARs that ultimately vest will expire on the tenth anniversary of the grant date or within a specified period following any earlier termination of employment. Upon exercise, each SAR must be settled for cash in the amount by which the per share fair value of Holdings’ common stock on the exercise date exceeds the agreed upon per share fair value on the acquisition date. The fair value of Holdings’ common stock is determined using the product of the trailing 12-month specified performance measure for Holdings and a specified median market price multiple based on a basket of public home health companies.Information regarding the net cash paid for the acquisition of Encompass is as follows (in millions):Fair value of assets acquired, net of $20.9 million of cash acquired$260.1Goodwill592.5Fair value of liabilities assumed(113.5)Redeemable noncontrolling interests(64.5)Net cash paid for acquisition$674.6As a result of the acquisition of Encompass, in the first quarter of 2015, management changed the way it manages and operates the consolidated reporting entity and modified the reports used by its chief operating decision maker to assess performance and allocate resources. These changes will require us to revise our segment reporting from our historic presentation of only one reportable segment. Beginning in the first quarter of 2015, we will manage our operations and disclose financial information using two reportable segments: (1) inpatient rehabilitation and (2) home health and hospice.Other AcquisitionsIn June 2014, using cash on hand, we acquired an additional 30% equity interest from UMass Memorial Health Care, our joint venture partner in Fairlawn Rehabilitation Hospital (“Fairlawn”) in Worcester, Massachusetts. This transaction increased our ownership interest from 50% to 80% and resulted in a change in accounting for this hospital from the equity method of accounting to a consolidated entity. As a result of our consolidation of this hospital and the remeasurement of our previously held equity interest at fair value, Goodwill increased by $34.0 million, and we recorded a $27.2 million gain as part of Other income during 2014. The Fairlawn transaction was made to increase our ownership in a profitable hospital and continue to grow our core business by consolidating its operations. None of the goodwill resulting from this transaction is deductible for federal income tax purposes. See also Note 16,Income Taxes.In November 2014, we acquired 50.1% of the James H. & Cecile C. Quillen Rehabilitation Hospital (“Quillen”), a 26-bed inpatient rehabilitation hospital in Johnson City, Tennessee, through a joint venture with Mountain States Health Alliance. The joint venture, which was funded using cash on hand, was not material to our financial position, results of operations, or cash flows. The Quillen transaction was made to enhance our position and ability to provide inpatient rehabilitative services to patients in Johnson City and its surrounding areas. As a result of this transaction, Goodwill increased by $0.6 million, none of which is deductible for federal income tax purposes. The noncontrolling interest associated with this agreement includes redemption features that are not solely within our control and, therefore, is considered Redeemable noncontrolling interests. See Note 11,Redeemable Noncontrolling Interests.In April 2013, we closed the transaction to acquire Walton Rehabilitation Hospital, a 58-bed inpatient rehabilitation hospital in Augusta, Georgia. This acquisition was made to enhance our position and ability to provide inpatient rehabilitative services to patients in Augusta, Georgia and its surrounding areas. The acquisition, which was funded using availability under our revolving credit facility, was not material to our financial position, results of operations, or cash flows. As a result of this transaction, Goodwill increased by $13.7 million, all of which is deductible for federal income tax purposes.In April 2012, we acquired 12 inpatient rehabilitation beds in Andalusia, Alabama from a subsidiary of LifePoint Hospitals in order to add beds at our existing hospital in Dothan, Alabama. In July 2012, we acquired the 34-bed inpatient rehabilitation unit of CHRISTUS Santa Rosa Hospital - Medical Center. The operations of this unit have been relocated to and consolidated with our existing hospital in San Antonio, Texas. Both transactions were made to enhance our position and ability to provide inpatient rehabilitative services to patients in the respective areas. These transactions, either individually or in the aggregate, were not material to our financial position, results of operations, or cash flows. Goodwill did not increase as a result of these transactions. Both acquisitions were funded with available cash.We accounted for all of these transactions under the acquisition method of accounting and reported the results of operations of the acquired or newly consolidated hospitals from their respective dates of acquisition. Assets acquired and liabilities assumed were recorded at their estimated fair values as of the respective acquisition dates. The fair values of identifiable intangible assets were based on valuations using the cost and income approaches. The cost approach is based on amounts that would be required to replace the asset (i.e., replacement cost). The income approach is based on management’s estimates of future operating results and cash flows discounted using a weighted-average cost of capital that reflects market participant assumptions. The excess of the fair value of the consideration conveyed over the fair value of the net assets acquired was recorded as goodwill. The goodwill reflects our expectations of our ability to gain access to and penetrate the acquired or consolidated hospitals’ historical patient base and the benefits of being able to leverage operational efficiencies with favorable growth opportunities based on positive demographic trends in these markets.The fair value of the assets acquired and liabilities assumed at the acquisition dates for the Fairlawn and Quillen transactions completed in 2014 were as follows (in millions):Total current assets$12.1Property and equipment, net36.9Identifiable intangible assets: Noncompete agreements (useful lives of 2 to 3 years)0.4Trade names (useful lives of 20 years)2.9Certificates of need (useful lives of 20 years)10.8Licenses (useful lives of 20 years)2.1Goodwill34.6Total assets acquired99.8Total current liabilities assumed(7.8)Total long-term liabilities assumed(13.4)Net assets acquired$78.6Information regarding the net cash paid for all other acquisitions during each period presented is as follows (in millions): For the Year Ended December 31, 2014 2013 2012Fair value of assets acquired, net of $5.1 million of cash acquired in 2014$60.1 $15.6 $3.1Goodwill34.6 13.7 —Fair value of liabilities assumed(21.2) (0.4) —Fair value of noncontrolling interest owned by joint venture partner(18.3) — —Fair value of equity interest prior to acquisition(35.0) — —Net cash paid for acquisitions$20.2 $28.9 $3.1See also Note 7,Investments in and Advances to Nonconsolidated Affiliates.Pro Forma Results of OperationsThe following table summarizes the results of operations of the above mentioned transactions from their respective dates of acquisition included in our consolidated results of operations and the unaudited pro forma results of operations of the combined entity had the date of the acquisitions been January 1, 2013 (in millions): Net OperatingRevenues Net IncomeAttributable toHealthSouthAcquired entities only: Actual from acquisition date to December 31, 2014*$27.2 $4.0Combined entity: Supplemental pro forma from 1/01/2014-12/31/2014 (unaudited)2,799.8 237.5Combined entity: Supplemental pro forma from 1/01/2013-12/31/2013 (unaudited)2,627.6 311.3* Encompass - Actual amounts are zero due to the acquisition of Encompass on December 31, 2014.Fairlawn - includes operating results from June 1, 2014 through December 31, 2014Quillen - includes operating results from November 1, 2014 through December 31, 2014The information presented above is for illustrative purposes only and is not necessarily indicative of results that would have been achieved if the acquisitions had occurred as of the beginning of our 2013 reporting period.
