Business Combinations [Abstract]

Business Acquisition, Pro Forma Information

The following unaudited pro forma combined financial information reflects the consolidated statement of operations of the Company as if the acquisitions of Solstas and Summit Health had occurred as of January 1, 2013. The pro forma information includes adjustments primarily related to the amortization of intangible assets acquired, interest expense associated with debt extinguished prior to the acquisitions, and transaction costs related to the Solstas and Summit Health acquisitions. The unaudited pro forma combined financial information does not include the estimated annual synergies expected to be realized upon completion of the integration of Solstas and Summit Health and is not indicative of the results of operations as they would have been had the transaction been effected on the assumed date. Financial information for Steward has not been included in the table below as this acquisition is not material to the Company’s interim unaudited consolidated financial statements.
