Accounting Policies [Abstract] |
Consolidation and Presentation | Consolidation The consolidated financial statements include the accounts of Molina Healthcare, Inc., its subsidiaries, and variable interest entities in which Molina Healthcare, Inc. is considered to be the primary beneficiary. See Note 18, “Variable Interest Entities (VIEs),” for more information regarding these variable interest entities. All significant inter-company balances and transactions have been eliminated in consolidation. Financial information related to subsidiaries acquired during any year is included only for periods subsequent to their acquisition. In the opinion of management, all adjustments considered necessary for a fair presentation of the results as of the date and for the periods presented have been included; such adjustments consist of normal recurring adjustments. Presentation and Reclassification The Centers for Medicare and Medicaid Services (CMS) incorporates the Health Insurer Fee (HIF) in our Medicare and Marketplace premium rates. We have therefore reclassified such amounts in our consolidated statements of operations to premium revenue, from health insurer fees reimbursed, for all applicable periods presented.
Use of Estimates | Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities. Estimates also affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Principal areas requiring the use of estimates include:
• | The determination of medical claims and benefits payable of our Health Plans segment;
• | Health plan contractual provisions that may limit revenue recognition based upon the costs incurred or the profits realized under a specific contract;
• | Health plan quality incentives that allow us to recognize incremental revenue if certain quality standards are met;
• | Molina Medicaid Solutions segment revenue and cost recognition;
• | Settlements under risk or savings sharing programs;
• | The assessment of deferred contract costs, deferred revenue, long-lived and intangible assets, and goodwill for impairment;
• | The determination of reserves for potential absorption of claims unpaid by insolvent providers;
• | The determination of reserves for the outcome of litigation;
• | The determination of valuation allowances for deferred tax assets; and
• | The determination of unrecognized tax benefits.
Cash and Cash Equivalents | Cash and Cash Equivalents Cash and cash equivalents consist of cash and short-term, highly liquid investments that are both readily convertible into known amounts of cash and have a maturity of three months or less on the date of purchase.
Investments | Investments Our investments are principally held in debt securities, which are grouped into two separate categories for accounting and reporting purposes: available-for-sale securities, and held-to-maturity securities. Available-for-sale securities are recorded at fair value and unrealized gains and losses, if any, are recorded in stockholders’ equity as other comprehensive income, net of applicable income taxes. Held-to-maturity securities are recorded at amortized cost, which approximates fair value, and unrealized holding gains or losses are not generally recognized. Realized gains and losses and unrealized losses judged to be other than temporary with respect to available-for-sale and held-to-maturity securities are included in the determination of net (loss) income. The cost of securities sold is determined using the specific-identification method. Our investment policy requires that all of our investments have final maturities of 10 years or less (excluding variable rate securities where interest rates may be periodically reset), and that the average maturity be three years or less. Investments and restricted investments are subject to interest rate risk and will decrease in value if market rates increase. Declines in interest rates over time will reduce our investment income. In general, our available-for-sale securities are classified as current assets without regard to the securities’ contractual maturity dates because they may be readily liquidated. We monitor our investments for other-than-temporary impairment.
Long-Lived Assets, Including Intangible Assets | Long-Lived Assets, including Intangible Assets Long-lived assets consist primarily of property, equipment, capitalized software (see Note 7, “Property, Equipment, and Capitalized Software, Net”), and intangible assets (see Note 8, “Goodwill and Intangible Assets, Net”). Property and equipment are stated at historical cost. Replacements and major improvements are capitalized, and repairs and maintenance are charged to expense as incurred. Furniture and equipment are generally depreciated using the straight-line method over estimated useful lives ranging from three to seven years. Software developed for internal use is capitalized. Software is generally amortized over its estimated useful life of three years. Leasehold improvements are amortized over the term of the lease, or over their useful lives from five to 10 years, whichever is shorter. Buildings are depreciated over their estimated useful lives of 31.5 to 40 years. The costs associated with certain of our Molina Medicaid Solutions segment equipment and software are capitalized and recorded as deferred contract costs. Such costs are amortized on a straight-line basis over the shorter of the useful life or the contract period, and the amortization is recorded within the heading “Cost of service revenue.”
Deferred Contract Costs | Deferred Contract Costs Direct costs associated with our Molina Medicaid Solutions contracts, other than software-related costs for which we apply the guidance for internal-use software, are expensed as incurred unless corresponding revenue is deferred. We defer recognition of any contingent revenue until the contingency has been removed. If revenue is deferred, direct costs relating to delivered service elements are deferred as well, and recognized on a straight-line basis over the period of revenue recognition. The recoverability of deferred contract costs associated with a particular contract is analyzed on a periodic basis using the undiscounted estimated cash flows of the whole contract over its remaining contract term. If such undiscounted cash flows are insufficient to recover the long-lived assets and deferred contract costs, the deferred contract costs are written down by the amount of the cash flow deficiency. If a cash flow deficiency remains after reducing the balance of the deferred contract costs to zero, any remaining long-lived assets are evaluated for impairment. Any such impairment recognized would equal the amount by which the carrying value of the long-lived assets exceeds the fair value of those assets.
Business Combinations | Business Combinations Accounting for acquisitions requires us to recognize separately from goodwill the assets acquired and the liabilities assumed at their acquisition date fair values. Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations. While we use our best estimates and assumptions to accurately value assets acquired and liabilities assumed at the acquisition date, our estimates are inherently uncertain and subject to refinement. As a result, during the measurement period, which may be up to one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. Upon the conclusion of the final determination of the values of assets acquired or liabilities assumed, or one year after the date of acquisition, whichever comes first, any subsequent adjustments are recorded within our consolidated statements of operations.
Premium Revenue - Health Plans | Premium Revenue - Health Plans Premium revenue is generated primarily from our Medicaid, Medicare and Marketplace contracts, including agreements with other managed care organizations for which we operate as a subcontractor. Premium revenue is generally received based on per member per month (PMPM) rates established in advance of the periods covered. These premium revenues are recognized in the month that members are entitled to receive health care services, and premiums collected in advance are deferred. The state Medicaid programs and the federal Medicare program periodically adjust premiums. Additionally, many of our contracts contain provisions that may adjust or limit revenue or profit, as described below. Consequently, we recognize premium revenue as it is earned under such provisions. The following table summarizes premium revenue for the periods indicated:
| Year Ended December 31,

Certain components of premium revenue are subject to accounting estimates and fall into the following categories: Contractual Provisions That May Adjust or Limit Revenue or Profit Medicaid Medical Cost Floors (Minimums), and Medical Cost Corridors. A portion of our premium revenue may be returned if certain minimum amounts are not spent on defined medical care costs. In the aggregate, we recorded a liability under the terms of such contract provisions of $135 million and $272 million at December 31, 2017 and December 31, 2016, respectively, to amounts due government agencies. Approximately $96 million and $244 million of the liability accrued at December 31, 2017 and December 31, 2016, respectively, relates to our participation in Medicaid Expansion programs. In certain circumstances, the health plans may receive additional premiums if amounts spent on medical care costs exceed a defined maximum threshold. Receivables relating to such provisions were insignificant at December 31, 2017 and December 31, 2016. Profit Sharing and Profit Ceiling. Our contracts with certain states contain profit-sharing or profit ceiling provisions under which we refund amounts to the states if our health plans generate profit above a certain specified percentage. In some cases, we are limited in the amount of administrative costs that we may deduct in calculating the refund, if any. Liabilities for profits in excess of the amount we are allowed to retain under these provisions were insignificant at December 31, 2017 and December 31, 2016. Retroactive Premium Adjustments. State Medicaid programs periodically adjust premium rates on a retroactive basis. In these cases, we must adjust our premium revenue in the period in which we learn of the adjustment, rather than in the months of service to which the retroactive adjustment applies. Medicare Risk Adjustment: Our Medicare premiums are subject to retroactive increase or decrease based on the health status of our Medicare members (as measured by member risk score). We estimate our members’ risk scores and the related amount of Medicare revenue that will ultimately be realized for the periods presented based on our knowledge of our members’ health status, risk scores and CMS practices. Consolidated balance sheet amounts related to anticipated Medicare risk adjustment premiums and Medicare Part D settlements were insignificant at December 31, 2017 and December 31, 2016. Minimum MLR: Additionally, federal regulations have established a minimum annual medical loss ratio (Minimum MLR) of 85% for Medicare. The medical loss ratio represents medical costs as a percentage of premium revenue. Federal regulations define what constitutes medical costs and premium revenue. If the Minimum MLR is not met, we may be required to pay rebates to the federal government. We recognize estimated rebates under the Minimum MLR as an adjustment to premium revenue in our consolidated statements of operations. Marketplace Premium Stabilization Programs: The Affordable Care Act (ACA) established Marketplace premium stabilization programs effective January 1, 2014. These programs, commonly referred to as the “3R’s,” include a permanent risk adjustment program, a transitional reinsurance program, and a temporary risk corridor program. We record receivables or payables related to the 3R programs and the Minimum MLR when the amounts are reasonably estimable as described below, and, for receivables, when collection is reasonably assured. Our receivables (payables) for each of these programs, as of the dates indicated, were as follows:
| December 31, 2017 |  | December 31, 2016
| Current Benefit Year |  | Prior Benefit Years |  | Total |
| (In millions)
Risk adjustment | $ | (912 | ) |  | $ | — |  |  | $ | (912 | ) |  | $ | (522 | )
Reinsurance | — |  |  | 10 |  |  | 10 |  |  | 55 |
Risk corridor | — |  |  | — |  |  | — |  |  | (1 | )
Minimum MLR | (2 | ) |  | — |  |  | (2 | ) |  | (1 | )
• | Risk adjustment: Under this permanent program, our health plans’ composite risk scores are compared with the overall average risk score for the relevant state and market pool. Generally, our health plans will make a risk transfer payment into the pool if their composite risk scores are below the average risk score, and will receive a risk transfer payment from the pool if their composite risk scores are above the average risk score. We estimate our ultimate premium based on insurance policy year-to-date experience, and recognize estimated premiums relating to the risk adjustment program as an adjustment to premium revenue in our consolidated statements of operations.
• | Reinsurance: This program was designed to provide reimbursement to insurers for high cost members and ended December 31, 2016; we expect to settle the outstanding receivable balance in the first quarter of 2018.
• | Risk corridor: This program was intended to limit gains and losses of insurers by comparing allowable costs to a target amount as defined by CMS, and ended December 31, 2016; all outstanding payable balances were settled in the third quarter of 2017. We are owed, but have not recorded $128 million in risk corridor payments from CMS related to benefit year 2016 and 2015.
Additionally, the ACA established a Minimum MLR of 80% for the Marketplace. The medical loss ratio represents medical costs as a percentage of premium revenue. Federal regulations define what constitutes medical costs and premium revenue. If the Minimum MLR is not met, we may be required to pay rebates to our Marketplace policyholders. Each of the 3R programs is taken into consideration when computing the Minimum MLR. We recognize estimated rebates under the Minimum MLR as an adjustment to premium revenue in our consolidated statements of operations. Quality Incentives At several of our health plans, revenue ranging from approximately 1% to 3% of certain health plan premiums is earned only if certain performance measures are met.
Medical Care Costs - Health Plans | Medical Care Costs - Health Plans Expenses related to medical care services are captured in the following categories: Fee-for-service expenses. Nearly all hospital services and the majority of our primary care and physician specialist services and LTSS costs are paid on a fee-for-service basis. Under fee-for-service arrangements, we retain the financial responsibility for medical care provided and incur costs based on actual utilization of services. Such expenses are recorded in the period in which the related services are dispensed. The costs of drugs administered in a physician or hospital setting that are not billed through our pharmacy benefit manager are included in fee-for-service costs. Pharmacy expenses. All drug, injectibles, and immunization costs paid through our pharmacy benefit manager are classified as pharmacy expenses. As noted above, drugs and injectibles not paid through our pharmacy benefit manager are included in fee-for-service costs, except in those limited instances where we capitate drug and injectible costs. Capitation expenses. Many of our primary care physicians and a small number of our specialists and hospitals are paid on a capitated basis. Under capitation arrangements, we pay a fixed amount PMPM to the provider without regard to the frequency, extent, or nature of the medical services actually furnished. Under capitated arrangements, we remain liable for the provision of certain health care services. Capitation payments are fixed in advance of the periods covered and are not subject to significant accounting estimates. These payments are expensed in the period the providers are obligated to provide services. The financial risk for pharmacy services for a small portion of our membership is delegated to capitated providers. Direct delivery expenses. All costs associated with our direct delivery of medical care are separately identified. Other medical expenses. All medically related administrative costs, certain provider incentive costs, and other health care expenses are classified as other medical expenses. Medically related administrative costs include, for example, expenses relating to health education, quality assurance, case management, care coordination, disease management, and 24-hour on-call nurses. Salary and benefit costs are a substantial portion of these expenses. For the years ended December 31, 2017, 2016, and 2015, medically related administrative costs were $554 million, $488 million, and $398 million, respectively. The following table provides the details of our consolidated medical care costs for the periods indicated (dollars in millions, except PMPM amounts):
| Year Ended December 31,
| 2017 |  | 2016 |  | 2015
| Amount |  | PMPM |  | % of Total |  | Amount |  | PMPM |  | % of Total |  | Amount |  | PMPM |  | % of Total
Fee-for-service | $ | 12,682 |  |  | $ | 229.63 |  |  | 74.3 | % |  | $ | 10,993 |  |  | $ | 217.84 |  |  | 74.4 | % |  | $ | 8,572 |  |  | $ | 218.35 |  |  | 72.7 | %
Pharmacy | 2,563 |  |  | 46.40 |  |  | 15.0 |  |  | 2,213 |  |  | 43.84 |  |  | 15.0 |  |  | 1,610 |  |  | 41.01 |  |  | 13.7 |
Capitation | 1,360 |  |  | 24.63 |  |  | 8.0 |  |  | 1,218 |  |  | 24.13 |  |  | 8.2 |  |  | 982 |  |  | 25.02 |  |  | 8.3 |
Direct delivery | 73 |  |  | 1.33 |  |  | 0.4 |  |  | 78 |  |  | 1.55 |  |  | 0.5 |  |  | 128 |  |  | 3.26 |  |  | 1.1 |
Other | 395 |  |  | 7.15 |  |  | 2.3 |  |  | 272 |  |  | 5.39 |  |  | 1.9 |  |  | 502 |  |  | 12.79 |  |  | 4.2 |
Total | $ | 17,073 |  |  | $ | 309.14 |  |  | 100.0 | % |  | $ | 14,774 |  |  | $ | 292.75 |  |  | 100.0 | % |  | $ | 11,794 |  |  | $ | 300.43 |  |  | 100.0 | %
Our medical care costs include amounts that have been paid by us through the reporting date, as well as estimated liabilities for medical care costs incurred but not paid by us as of the reporting date. Such medical care cost liabilities include, among other items, unpaid fee-for-service claims, capitation payments owed providers, unpaid pharmacy invoices, and various medically related administrative costs that have been incurred but not paid. We use judgment to determine the appropriate assumptions for determining the required estimates. The most important element in estimating our medical care costs is our estimate for fee-for-service claims which have been incurred but not paid by us. These fee-for-service costs that have been incurred but have not been paid at the reporting date are collectively referred to as medical costs that are incurred but not paid (IBNP). Our IBNP claims reserve, as reported in our balance sheet, represents our best estimate of the total amount of claims we will ultimately pay with respect to claims that we have incurred as of the balance sheet date. We estimate our IBNP monthly using actuarial methods based on a number of factors. For further information, see Note 10, “Medical Claims and Benefits Payable.” We report reinsurance premiums as a reduction to premium revenue, while related reinsurance recoveries are reported as a reduction to medical care costs. We limit our risk of catastrophic losses by maintaining high deductible reinsurance coverage. Such reinsurance coverage does not relieve us of our primary obligation to our policyholders. We do not consider this coverage to be material because the cost is not significant and the likelihood that coverage will apply is low.
Taxes Based on Premiums | Taxes Based on Premiums Health Insurer Fee (HIF). The federal government under the ACA imposes an annual fee, or excise tax, on health insurers for each calendar year. The HIF is based on a company’s share of the industry’s net premiums written during the preceding calendar year, and is non-deductible for income tax purposes. We recognize expense for the HIF over the year on a straight-line basis. Within our Medicaid program, we must secure additional reimbursement from our state partners for this added cost. We recognize the related revenue when we have obtained a contractual commitment or payment from a state to reimburse us for the HIF; such HIF revenue is recognized ratably throughout the year. The Consolidated Appropriations Act of 2016 provided for a HIF moratorium in 2017. Therefore, there were no health insurer fees reimbursed, nor health insurer fees incurred, in 2017. Premium and Use Tax. Certain of our health plans are assessed a tax based on premium revenue collected. The premium revenues we receive from these states include the premium tax assessment. We have reported these taxes on a gross basis, as premium tax revenue and as premium tax expenses in the consolidated statements of operations.
Premium Deficiency Reserves on Loss Contracts | Premium Deficiency Reserves on Loss Contracts We assess the profitability of our medical care policies to identify groups of contracts where current operating results or forecasts indicate probable future losses. If anticipated future variable costs exceed anticipated future premiums and investment income, a premium deficiency reserve is recognized.
Concentrations of Credit Risk | Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash and cash equivalents, investments, receivables, and restricted investments. Our investments and a portion of our cash equivalents are managed by professional portfolio managers operating under documented investment guidelines. Our portfolio managers must obtain our prior approval before selling investments where the loss position of those investments exceeds certain levels. Our investments consist primarily of investment-grade debt securities with a maximum maturity of 10 years and an average duration of three years or less. Restricted investments, non-current are invested principally in certificates of deposit and U.S. treasury securities. Concentration of credit risk with respect to accounts receivable is limited because our payors consist principally of the governments of each state in which our health plan subsidiaries operate.
Risks and Uncertainties | Risks and Uncertainties Our profitability depends in large part on our ability to accurately predict and effectively manage medical care costs. We continually review our medical costs in light of our underlying claims experience and revised actuarial data. However, several factors could adversely affect medical care costs. These factors, which include changes in health care practices, inflation, new technologies, major epidemics, natural disasters, and malpractice litigation, are beyond our control and may have an adverse effect on our ability to accurately predict and effectively control medical care costs. Costs in excess of those anticipated could have a material adverse effect on our financial condition, results of operations, or cash flows. We operate health plans primarily as a direct contractor with the states (or Commonwealth), and in Los Angeles County, California, as a subcontractor to another health plan holding a direct contract with the state. We are therefore dependent upon a small number of contracts to support our revenue. The loss of any one of those contracts could have a material adverse effect on our financial position, results of operations, or cash flows. Our ability to arrange for the provision of medical services to our members is dependent upon our ability to develop and maintain adequate provider networks. Our inability to develop or maintain such networks might, in certain circumstances, have a material adverse effect on our financial position, results of operations, or cash flows.
Recent Accounting Pronouncements Not Yet Adopted and Recent Accounting Pronouncements Adopted | Recent Accounting Pronouncements Comprehensive Income. In February 2018, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017. ASU 2018-02 also requires certain disclosures about stranded tax effects. ASU 2018-02 is effective beginning January 1, 2019; we early adopted this ASU effective January 1, 2018, with no material impact to our financial condition, results of operations or cash flows. We are currently evaluating the required disclosures. Goodwill Impairment. In January 2017, FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment loss. Instead, an impairment loss is measured as the excess of the carrying amount of the reporting unit, including goodwill, over the fair value of the reporting unit. ASU 2017-04 is effective beginning January 1, 2020; we early adopted ASU 2017-04 as of June 30, 2017, in connection with the interim assessment of our Pathways subsidiary. See further discussion at Note 8, “Goodwill and Intangible Assets, Net.” Restricted Cash. In November 2016, the FASB issued ASU 2016-18, Restricted Cash, which will require us to include in our consolidated statements of cash flows the balances of cash, cash equivalents, restricted cash and restricted cash equivalents. When these items are presented in more than one line item on the balance sheet, the new guidance requires a reconciliation of the totals in the statement of cash flows to the related captions in the balance sheet. Transfers between cash and cash equivalents and restricted cash and restricted cash equivalents will no longer be presented in the statement of cash flows. ASU 2016-18 is effective beginning January 1, 2018. We are currently evaluating the classification changes that will be required in our presentation of the consolidated statements of cash flows. Stock Compensation. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which amends ASC Topic 718, Compensation – Stock Compensation. ASU 2016-09 simplifies several aspects of accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, statutory tax and classification in the statement of cash flows. We adopted ASU 2016-09 on January 1, 2017; such adoption did not significantly impact our consolidated financial statements. In addition, the prior period presentation in the statement of cash flows was not adjusted because such adjustments were insignificant. Leases. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), as modified by ASU 2017-03, Transition and Open Effective Date Information. Under ASU 2016-02, an entity will be required to recognize assets and liabilities for the rights and obligations created by leases on the entity’s balance sheet for both finance and operating leases. For leases with a term of 12 months or less, an entity can elect to not recognize lease assets and lease liabilities and expense the lease over a straight-line basis for the term of the lease. ASU 2016-02 will require new disclosures that depict the amount, timing, and uncertainty of cash flows pertaining to an entity’s leases. ASU 2016-02 is effective beginning January 1, 2019, and must be adopted using a modified retrospective approach for annual and interim periods beginning after December 15, 2018. Under this guidance, we will record assets and liabilities relating primarily to our long-term office leases. We are in the early stages of evaluating the effect to our consolidated financial statements. Financial Instruments. In January 2016, the FASB issued ASU 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities, which will require public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. Also, entities will have to assess the realizability of a deferred tax asset related to an available-for-sale debt security in combination with the entity’s other deferred tax assets. Effective on January 1, 2018, ASU 2016-01 is applied prospectively with a cumulative-effect adjustment to beginning retained earnings as of the beginning of the first reporting period in which the guidance is adopted. We have determined that there will be no impact to beginning retained earnings; we are in the process of determining the changes to required disclosures. Revenue Recognition. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). We intend to adopt this standard and the related modifications on January 1, 2018, using the modified retrospective approach. Under this approach, the cumulative effect of initially applying the guidance will be reflected as an adjustment to beginning retained earnings. We have determined that the insurance contracts of our Health Plans segment, which segment constitutes the vast majority of our operations, are excluded from the scope of Topic 606 because the recognition of revenue under these contracts is dictated by other accounting standards governing insurance contracts. For our Molina Medicaid Solutions segment, we have determined that revenue for contracts that include design, development and implementation (DDI) of Medicaid management information systems shall be deferred until the system ‘go-live’ date, and then generally recognized on a straight-line basis over the hosting period. This approach is similar to our historical revenue recognition methodology, with two exceptions. First, revenues contingent upon a state’s acceptance of DDI and other services were previously deferred until the contingency was removed. Under Topic 606, we have determined that such revenues are appropriately recognized at the system ‘go-live’ date as noted above, resulting in a slight acceleration of revenue under Topic 606. Second, contract extensions were previously considered a single unit of account with the original contracts. Under Topic 606, contract extensions are considered to be standalone contracts, so revenues previously deferred over the original contract plus extension periods are now recognized over the original contract period, resulting in slightly accelerated revenue recognition. Cost of service revenue continues to be recognized in a manner consistent with the corresponding revenue recognition. As a result, the cumulative adjustment to retained earnings associated with the adoption of Topic 606 effective January 1, 2018, is insignificant for our Molina Medicaid Solutions segment. For our Pathways behavioral health and social services provider, which is reported in the Other segment, there is no substantive change to revenue recognition under Topic 606, and therefore no impact to retained earnings effective January 1, 2018. Other recent accounting pronouncements issued by the FASB (including its Emerging Issues Task Force), the American Institute of Certified Public Accountants, and the Securities and Exchange Commission (SEC) did not have, or are not believed by management to have, a significant impact on our present or future consolidated financial statements.
Receivables | Receivables consist primarily of amounts due from government Medicaid agencies, which may be subject to potential retroactive adjustments. Because all of our receivable amounts are readily determinable and substantially all of our creditors are governmental authorities, our allowance for doubtful accounts is insignificant. Any amounts determined to be uncollectible are charged to expense when such determination is made.
Goodwill | Goodwill represents the excess of the purchase price over the fair value of net assets acquired in business combinations. Goodwill is not amortized, but is tested for impairment on an annual basis and more frequently if impairment indicators are present. When testing goodwill for impairment, we may first assess qualitative factors, such as industry and market factors, cost factors, and changes in overall performance, to determine if it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value. If our qualitative assessment indicates that it is more likely than not that the carrying value of a reporting unit exceeds its estimated fair value, we perform the quantitative assessment. We may also elect to bypass the qualitative assessment and proceed directly to the quantitative assessment. We estimated the fair values of our reporting units using the higher of the income approach using discounted cash flows, or the asset liquidation method. For the annual impairment test, the base year in the reporting units’ discounted cash flows is derived from the most recent annual financial budgeting cycle, for which the planning process commences in the fourth quarter of the year. When computing discounted cash flows, we make assumptions about a wide variety of internal and external factors, and consider what the reporting unit’s selling price would be in an orderly transaction between market participants at the measurement date. Significant assumptions include financial projections of free cash flow (including significant assumptions about operations, capital requirements and income taxes), long-term growth rates for determining terminal value beyond the discretely forecasted periods, and discount rates. When determining the discount rate, we consider the overall level of inherent risk of the reporting unit, and the expected rate an outside investor would expect to earn. The asset liquidation method is computed as total assets minus total liabilities, excluding intangible assets and liabilities.
Income Taxes | The (benefit) provision for income taxes is determined using an estimated annual effective tax rate, which generally differs from the U.S. federal statutory rate primarily because of state taxes, nondeductible expenses such as the HIF, goodwill impairment, certain compensation, and other general and administrative expenses. The effective tax rate was not impacted by the HIF in 2017, given the 2017 HIF moratorium. The effective tax rate may be subject to fluctuations during the year, particularly as a result of the level of pretax earnings, and also as new information is obtained. Such information may affect the assumptions used to estimate the annual effective tax rate, including factors such as the mix of pretax earnings in the various tax jurisdictions in which we operate, valuation allowances against deferred tax assets, the recognition or the reversal of the recognition of tax benefits related to uncertain tax positions, and changes in or the interpretation of tax laws in jurisdictions where we conduct business. We recognize deferred tax assets and liabilities for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities, along with net operating loss and tax credit carryovers. The Tax Cuts and Jobs Act (TCJA) was enacted on December 22, 2017. The TCJA, in part, reduces the U.S. federal corporate tax rate from 35% to 21% effective January 1, 2018. TCJA’s change in the federal rate requires that we revalue deferred tax assets and liabilities based on the rates at which they are expected to reverse in the future, which is generally the new 21% federal corporate tax rate plus applicable state tax rate. At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the TCJA; however, we have made a reasonable estimate of the effects on our existing deferred tax balances and we recognized a provisional deferred federal income tax expense of $54 million, which is included as a reduction of income tax benefit for the year ended December 31, 2017. We will continue to make and refine our calculations as additional analysis is completed. In addition, our estimates may also be affected as we gain a more thorough understanding of the tax law based on expected future guidance from the Internal Revenue Service and U.S. Treasury.
