Accounting Policies [Abstract] |
Condensed consolidated interim financial statements | Condensed consolidated interim financial statements The condensed consolidated interim financial statements included in this report are prepared by the Company without audit. In the opinion of management, all adjustments necessary for a fair presentation of the results of operations are reflected in these condensed consolidated interim financial statements. All significant intercompany accounts and transactions have been eliminated. The preparation of these financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. The most significant estimates and assumptions underlying these financial statements and accompanying notes generally involve revenue recognition and accounts receivable, contingencies, impairments of goodwill and other long-lived assets, fair value estimates, accounting for income taxes, variable compensation accruals, consolidation of variable interest entities, purchase accounting valuation estimates, long-term incentive program compensation and medical liability claims. The results of operations for the six months ended June 30, 2017 are not necessarily indicative of the operating results for the full year. The condensed consolidated interim financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016. Prior year balances and amounts have been reclassified to conform to the current year presentation. The Company has evaluated subsequent events through the date these condensed consolidated financial statements were issued and has included all necessary adjustments and disclosures.
