Basis of Presentation, Summary of Significant Accounting Policies and Change in Accounting Principles | Basis of Presentation, Summary of Significant Accounting Policies and Change in Accounting Principle Basis of Presentation In our opinion, the accompanying unaudited interim consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to fairly state our financial position, results of operations, and cash flows. The consolidated balance sheet at December 31, 2018 , has been derived from audited financial statements as of that date. The interim consolidated results of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain footnote disclosures normally included in financial statements prepared in accordance with United States of America generally accepted accounting principles (“GAAP”) have been omitted pursuant to instructions, rules, and regulations prescribed by the United States Securities and Exchange Commission (“SEC”). The disclosures provided herein should be read in conjunction with the audited financial statements and notes thereto included in our 2018 Form 10-K. Summary of Significant Accounting Policies Certain GAAP policies that significantly affect the determination of our financial position, results of operations and cash flows, are summarized below. Accounting Estimates and Assumptions The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities and the disclosures of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses for the reporting period. Those estimates are inherently subject to change and actual results could differ from those estimates. In the accompanying consolidated financial statements, estimates are used for, but not limited to, the valuation of assets (including intangibles and long-lived assets), liabilities (including IBNR), consideration related to business combinations and asset acquisitions, revenue recognition (including variable consideration), estimated selling prices for performance obligations in contracts with multiple performance obligations, reserves for claims and performance-based arrangements, contingent payments, allowance for doubtful accounts, depreciable lives of assets, impairment of long-lived assets (including equity method investments), stock-based compensation, deferred income taxes and valuation allowance, contingent liabilities, valuation of intangible assets (including goodwill), purchase price allocation in taxable stock transactions and useful lives of intangible assets. Principles of Consolidation The consolidated financial statements include the accounts of Evolent Health, Inc. and its subsidiaries. All inter-company accounts and transactions are eliminated in consolidation. Operating Segments Operating segments are defined as components of a business that may recognize revenue and incur expenses for which discrete financial information is available that is evaluated, on a regular basis, by the chief operating decision maker (“CODM”) to decide how to allocate resources and assess performance. The Company operates through two segments: (1) Services, and (2) True Health. Our Services segment consists of our technology-enabled value-based care services, specialty care management services and comprehensive health plan administration services. Our True Health segment consists of a commercial health plan we operate in New Mexico that focuses on small and large businesses. See Note 18 for a discussion of our operating results by segment. Revenue Recognition Our Services segment derives revenue from two sources: (1) transformation services and (2) platform and operations services. Transformation services consist of implementation services whereby we assist the customer in launching its population health or health plan strategy. In certain cases, transformation services can also include revenue associated with our support of certain one-time wind-down activities for clients who are exiting a line of business or population. Platform and operations services generally include multi-year arrangements with customers to provide various population health, health plan operations, specialty care management (through performance-based arrangements) and claims processing services on an ongoing basis, as well as transition or run-out services to customers receiving primarily third-party administration (“TPA”) services. Revenue is recognized when control of the services is transferred to our customers. We use the following 5-step model, outlined in Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), to determine revenue recognition for our Services segment from our contracts with customers: • Identify the contract(s) with a customer • Identify the performance obligations in the contract • Determine the transaction price • Allocate the transaction price to performance obligations • Recognize revenue when (or as) the entity satisfies a performance obligation Our True Health segment derives revenue from premiums that are earned over the terms of the related insurance policies. True Health also derives revenue from reinsurance premiums assumed from NMHC under the terms of the reinsurance agreement (as defined in Note 9 ). The portion of premiums that will be earned in the future or are received prior to the effectiveness of the policy are deferred and reported as premiums received in advance. These amounts are generally classified as short-term deferred revenue on our consolidated balance sheets. See Note 5 for further discussion of our policies related to revenue recognition. Leases As discussed in Note 3 , we adopted Accounting Standards Update (“ASU”) 2016-02 effective January 1, 2019. The following reflects our updated policy for leases. The Company enters into various office space, data center, and equipment lease agreements in conducting its normal business operations. At the inception of any contract, the Company evaluates the agreement to determine whether the contract contains a lease. If the contract contains a lease, the Company then evaluates the term and whether the lease is an operating or finance lease. Most leases include one or more options to renew or may have a termination option. The Company determines whether these options are reasonably certain to be exercised at the inception of the lease. The rent expense is recognized on a straight-line basis in the consolidated statements of operations and comprehensive income (loss) over the term of the lease. Leases with an initial term of 12 months or less are not recorded on the balance sheet. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. Further, the Company treats all lease and non-lease components as a single combined lease component for all classes of underlying assets. The Company also enters into sublease agreements for some of its leased office space. Rental income attributable to subleases is immaterial and is offset against rent expense over the terms of the respective leases. Refer to Note 10 for additional lease disclosures. Restricted Cash and Restricted Investments Restricted cash and restricted investments include cash and investments used to collateralize various contractual obligations (in thousands) as follows: As of As of June 30, December 31, 2019 2018 Collateral for letters of credit for facility leases (1) $ 3,610 $ 3,710 Collateral with financial institutions (2) 37,876 34,142 Claims processing services (3) 2,933 122,439 Other 739 532 Total restricted cash and restricted investments 45,158 160,823 Current restricted investments 702 211 Current restricted cash 37,917 154,507 Total current restricted cash and restricted investments 38,619 154,718 Noncurrent restricted investments 110 607 Noncurrent restricted cash 6,429 5,498 Total noncurrent restricted cash and restricted investments $ 6,539 $ 6,105 (1) Represents restricted cash related to collateral for letters of credit required in conjunction with lease agreements. See Note 9 for further discussion of our lease commitments. (2) Represents collateral held with financial institutions for risk-sharing and other arrangements. As of June 30, 2019 , and December 31, 2018 , approximately $35.0 million and $31.2 million of the collateral amount was in a trust account and invested in a money market fund. The amounts invested in money market funds are considered restricted cash and are carried at fair value, which approximates cost. See Note 16 for discussion of our fair value measurement and Note 9 for discussion of our risk-sharing arrangements. As of June 30, 2019 , and December 31, 2018 , approximately $2.9 million of the collateral amount was held in FDIC participating bank accounts, primarily related to letters of credit. (3) Represents cash held by Evolent related to claims processing services on behalf of partners. These are pass-through amounts and can fluctuate materially from period to period depending on the timing of when the claims are processed. The following table provides a reconciliation of cash and cash equivalents and restricted cash reported within the consolidated balance sheets that sum to the total of the same such amounts shown in the statements of cash flows. As of June 30, 2019 2018 Cash and cash equivalents $ 92,821 $ 197,983 Restricted cash and restricted investments 45,158 57,054 Restricted investments included in restricted cash and restricted investments (812 ) (712 ) Total cash and cash equivalents and restricted cash shown in the consolidated statements of cash flows $ 137,167 $ 254,325 Notes Receivable Notes receivable are carried at the face amount of each note plus accrued interest receivable, less received payments. The Company does not typically carry notes receivable in the course of its regular business, but contributed $40.0 million in the form of an advance for regulatory capital requirements (the “Passport Note”) under an agreement with Passport, a current customer, entered into during the second quarter of 2019. The Passport Note carries a fixed interest rate of 6.5% per annum and is required to be repaid, plus accrued interest, in a single payment on July 1, 2025, the maturity date, or earlier, subject to regulatory approval. The Passport Note is required to be repaid out of surplus in excess of Passport’s obligations to its policyholders, claimant and beneficiary claims and all other creditors. As of June 30, 2019, the outstanding principal balance of the Passport Note was $40.0 million , excluding approximately $0.1 million of accrued interest. Business Combinations Companies acquired during each reporting period are reflected in the results of the Company effective from their respective dates of acquisition through the end of the reporting period. The Company allocates the fair value of purchase consideration to the assets acquired and liabilities assumed based on their estimated fair values at the acquisition date. Our estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. Critical estimates used to value certain identifiable assets include, but are not limited to, expected long-term revenues, future expected operating expenses, cost of capital, and appropriate discount rates. The excess of the fair value of purchase consideration over the fair value of the assets acquired and liabilities assumed in the acquired entity is recorded as goodwill. Goodwill is assigned to the reporting unit that benefits from the synergies arising from the business combination. If the Company obtains new information about facts and circumstances that existed as of the acquisition date during the measurement period, which may be up to one year from the acquisition date, the Company may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company's consolidated statements of operations and comprehensive income (loss). For contingent consideration recorded as a liability, the Company initially measures the amount at fair value as of the acquisition date and adjusts the liability, if needed, to fair value at each reporting period. Changes in the fair value of contingent consideration, other than measurement period adjustments, are recognized as operating income or expense. Acquisition-related expenses and post-acquisition restructuring costs are recognized separately from the business combination and are expensed as incurred. Goodwill We recognize the excess of the purchase price, plus the fair value of any non-controlling interests in the acquiree, over the fair value of identifiable net assets acquired as goodwill. Goodwill is not amortized, but is reviewed at least annually for indications of impairment, with consideration given to financial performance and other relevant factors. We perform impairment tests of goodwill at a reporting unit level, which is consistent with the way management evaluates our business. The Company has three reporting units: Legacy Services, New Century Health and True Health. Our annual goodwill impairment review occurs during the fourth quarter of each year. In interim periods between annual goodwill reviews, we also evaluate qualitative factors that could cause us to believe that it is more likely than not that the estimated fair value of each of our reporting units may be lower than the carrying value and trigger a quantitative assessment, including, but not limited to (i) macroeconomic conditions, (ii) industry and market considerations, (iii) our overall financial performance, including an analysis of our current and projected cash flows, revenues and earnings, (iv) a sustained decrease in share price and (v) other relevant entity-specific events including changes in management, strategy, partners, or litigation. If the Company determines that it is more likely than not that the fair value of a reporting unit is below the carrying amount, a quantitative goodwill assessment is required. In the quantitative evaluation, the fair value of the relevant reporting unit is determined and compared to the carrying value. If the fair value estimate of the relevant the reporting unit is greater than its carrying value, then the goodwill of the reporting unit is considered not impaired and no further action is required. If the fair value estimate of the relevant the reporting unit is less than its carrying value, goodwill is considered impaired for the amount by which the carrying amount exceeds the reporting unit’s fair value and a charge is reported in impairment of goodwill on our Consolidated Statements of Operations and Comprehensive Income (Loss). Intangible Assets, Net Identified intangible assets are recorded at their estimated fair values at the date of acquisition and are amortized over their respective estimated useful lives using a method of amortization that reflects the pattern in which the economic benefits of the intangible assets are used. Information regarding the determination and allocation of the fair value of recently acquired assets and liabilities is further described within Note 4 . The following summarizes the estimated useful lives by asset classification: Corporate trade name 10-20 years Customer relationships 10-25 years Technology 5 years Provider network contracts 5 years Intangible assets are reviewed for impairment if circumstances indicate the Company may not be able to recover the asset’s carrying value. The Company evaluates recoverability by determining whether the undiscounted cash flows expected to result from the use and eventual disposition of that asset or group exceed the carrying value at the evaluation date. If the undiscounted cash flows are not sufficient to cover the carrying value, the Company measures an impairment loss as the excess of the carrying amount of the long-lived asset or group over its fair value. See Note 7 for additional discussion regarding our intangible assets. Reserves for claims and performance-based arrangements Reserves for claims and performance-based arrangements for our Services and True Health segments reflect estimates of payments under performance-based arrangements and the ultimate cost of claims that have been incurred but not reported, including expected development on reported claims, those that have been reported but not yet paid (reported claims in process), and other medical care expenses and services payable that are primarily comprised of accruals for incentives and other amounts payable to health care professionals and facilities. Reserves for claims and performance-based arrangements also reflect estimated amounts owed to NMHC under a reinsurance agreement as discussed further in Note 9 . The Company uses actuarial principles and assumptions that are consistently applied in each reporting period and recognizes the actuarial best estimate of the ultimate liability along with a margin for adverse deviation. This approach is consistent with actuarial standards of practice that the liabilities be adequate under moderately adverse conditions. The process of estimating reserves involves a considerable degree of judgment by the Company and, as of any given date, is inherently uncertain. The methods for making such estimates and for establishing the resulting liability are continually reviewed, and adjustments are reflected in current results of operations in the period in which they are identified as experience develops or new information becomes known. See Note 19 for additional discussion regarding our reserves for claims and performance-based arrangements. Foreign Currency The Company formed a subsidiary in India during the first quarter of 2018. The functional currency of our international subsidiary is the Indian Rupee. We translate the financial statements of this subsidiary to U.S. dollars using month-end rates of exchange for assets and liabilities, and monthly average rates of exchange for revenue and expenses. Translation gains and losses are recorded in accumulated other comprehensive income (loss) as a component of shareholders' equity. Foreign currency translation gains and losses did not have a material impact on our consolidated statements of operations and comprehensive income (loss) for the three and six months ended June 30, 2019 and 2018 |
