Accounting Policies [Abstract]
Basis of Presentation and Recently Issued Accounting Pronouncements	2.Basis of Presentation and Recently Issued Accounting Pronouncements Principles of Consolidation The Company conducts its business through limited liability companies and C-corporations, each of which is a direct or indirect wholly owned subsidiary of the Company. The accompanying condensed consolidated financial statements include the accounts of the Company, its wholly owned subsidiaries, the accounts of variable interest entities (“VIEs”) in which the Company is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation. The Company consolidated six professional groups (“Professional Groups”) that constituted VIEs as of March 31, 2016. The Professional Groups are responsible for the supervision and delivery of medical services to the Company’s clients. The Company provides management services to the Professional Groups. Based on the Company’s ability to direct the activities that most significantly impact the economic performance of the Professional Groups, provide necessary funding and the obligation and likelihood of absorbing all expected gains and losses, the Company has determined that it is the primary beneficiary of these Professional Groups. The accompanying condensed consolidated balance sheets as of March 31, 2016 and December 31, 2015 include assets of $1.6 million and $1.4 million, respectively, and liabilities of $0.6 million as of both March 31, 2016 and December 31, 2015, related to the VIEs. The accompanying condensed consolidated statements of operations include net loss attributable to noncontrolling interest of $0.9 million and $0.6 million related to the VIEs for the three months ended March 31, 2016 and 2015, respectively. The accompanying condensed consolidated financial statements are unaudited, with the exception of the December 31, 2015 balance sheet, which is consistent with the audited financial statements at that date but does not include all of the information and footnotes required by U.S. generally accepted accounting principles (“GAAP”) for a complete set of financial statements. The information contained in these condensed consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto for the fiscal year ended December 31, 2015 included in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on March 9, 2016. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Recent Pronouncements In March 2016, the FASB issued ASU No. 2016-09, “Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). ASU 2016-09 requires that all excess tax benefits and tax deficiencies resulting from share-based payments be recognized as income tax expense or benefit in the income statement, which eliminates the accounting for additional paid-in capital pools. ASU 2016-09 also allows companies to make an entity-wide policy election to either estimate the number of stock-based awards that are expected to vest or account for forfeitures as they occur. With regards to the Statement of Cash Flows, both inflows and outflows of cash related to excess tax benefits will be classified as operating activities, whereas prior to this update, excess tax benefits as cash inflows were to be classified as financing activities. Also, cash paid by an employer when directly withholding shares for tax-withholding purposes (“net share settlement”) should now be classified as a financing activity. The new standard is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The Company is currently evaluating the impact that adoption of this new standard will have on its consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases”. The new standard establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for lessees for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company is currently evaluating the impact that adoption of this new standard will have on its consolidated financial statements. In September 2015, the FASB issued ASU 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments” (“ASU 2015-16”). ASU 2015-16 eliminates the requirement for an acquirer to retrospectively adjust its financial statements for changes to provisional amounts that are identified during the measurement-period following the consummation of a business combination. Instead, ASU 2015-16 requires these types of adjustments to be made during the reporting period in which they are identified and would require additional disclosure or separate presentation of the portion of the adjustment that would have been recorded in the previously reported periods as if the adjustment to the provisional amounts had been recognized as of the acquisition date. ASU 2015-16 is effective prospectively for fiscal years beginning after December 15, 2015, including interim periods within those years, with earlier application permitted for financial statements that have not been issued. The adoption of ASU 2015-16 is not expected to have a material impact on the Company’s results of operations. In April 2015, the FASB issued ASU No. 2015-05, “Intangibles – Goodwill and Other – Internal-Use Software.” The update is effective for financial statements issued for fiscal years beginning after December 15, 2015, and those interim periods within those fiscal years, with early adoption permitted. ASU 2015-05 provides guidance for customer’s accounting for fees paid in a cloud computing arrangement. If a cloud computing arrangement includes a software license, then the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. An entity can elect to adopt the amendments either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The adoption of ASU 2015-05 did not have a material impact on the Company’s condensed consolidated financial statements. In May 2014, the Financial Accounting Standards Board (“FASB”) and the International Accounting Standards Board issued Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers”, which outlines a single comprehensive model for recognizing revenue and supercedes most existing revenue recognition guidance, including guidance specific to the healthcare industry. Companies across all industries will use a new five-step model to recognize revenue from customer contracts. The new standard, which replaces nearly all existing GAAP and International Financial Reporting Standards revenue recognition guidance, will require significant management judgment in addition to changing the way many companies recognize revenue in their financial statements. The standard is effective for public entities for annual and interim periods beginning after December 15, 2017, with early adoption permitted for annual periods beginning after December 15, 2016. The Company is currently evaluating the impact that the adoption of this standard will have on its revenue recognition policies and procedures, financial position, result of operations, cash flows, financial disclosures and control framework.
