Organization and Significant Accounting Policies | Organization and Significant Accounting Policies Business Description The consolidated financial statements of Select Medical Holdings Corporation (“Holdings”) include the accounts of its wholly owned subsidiary, Select Medical Corporation (“Select”). Holdings conducts substantially all of its business through Select and its subsidiaries. Holdings and Select and its subsidiaries are collectively referred to as the “Company.” The Company is, based on number of facilities, one of the largest operators of critical illness recovery hospitals, rehabilitation hospitals, outpatient rehabilitation clinics, and occupational health centers in the United States. As of December 31, 2021, the Company had operations in 46 states and the District of Columbia. As of December 31, 2021, the Company operated 104 critical illness recovery hospitals, 30 rehabilitation hospitals, and 1,881 outpatient rehabilitation clinics. As of December 31, 2021, Concentra operated 518 occupational health centers and 134 onsite clinics at employer worksites. The Company operates through four business segments: the critical illness recovery hospital segment, the rehabilitation hospital segment, the outpatient rehabilitation segment, and the Concentra segment. The Company’s critical illness recovery hospital segment consists of hospitals designed to serve the needs of patients recovering from critical illnesses, often with complex medical needs, and the rehabilitation hospital segment consists of hospitals designed to serve patients that require intensive physical rehabilitation care. Patients are typically admitted to the Company’s critical illness recovery hospitals and rehabilitation hospitals from general acute care hospitals. The Company’s outpatient rehabilitation segment consists of clinics that provide physical, occupational, and speech rehabilitation services. The Company’s Concentra segment consists of occupational health centers that provide workers’ compensation injury care, physical therapy, and consumer health services and onsite clinics located at employer worksites that deliver occupational medicine services. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses. Estimates and assumptions are used for, but not limited to: revenue recognition, allowances for expected credit losses, estimated useful lives of assets, the fair value of goodwill and intangible assets, amounts payable for self-insured losses, and the computation of income taxes. Future events and their effects cannot be predicted with certainty; accordingly, the Company’s accounting estimates require the exercise of judgment. The accounting estimates used in the preparation of the financial statements will change as new events occur, as more experience is acquired, as additional information is obtained, and as the Company’s operating environment changes. The Company’s management evaluates and updates assumptions and estimates on an ongoing basis. Actual results could differ from those estimates. Principles of Consolidation The consolidated financial statements include the accounts of Holdings, Select, and the subsidiaries, limited liability companies, limited partnerships, and variable interest entities in which the Company has a controlling financial interest. All intercompany balances and transactions are eliminated in consolidation. Variable Interest Entities Certain states prohibit the “corporate practice of medicine,” which restricts the Company from owning medical practices which directly employ physicians and from exercising control over medical decisions by physicians. In these states, the Company enters into long-term management agreements with medical practices that are owned by licensed physicians which, in turn, employ or contract with physicians who provide professional medical services in certain of its occupational health centers and clinics. The agreements provide for the Company to direct the transfer of ownership of the medical practices to new licensed physicians at any time. Based on the provisions of the management agreements, the medical practices are variable interest entities for which the Company is the primary beneficiary. Non-Controlling Interests The ownership interests held by outside parties in subsidiaries, which include limited liability companies and limited partnerships, controlled by the Company are classified as non-controlling interests. Net income or loss is attributed to the Company’s non-controlling interests. Some of the Company’s non-controlling ownership interests consist of outside parties that have certain redemption rights that, if exercised, require the Company to purchase the parties’ ownership interests. These interests are classified and reported as redeemable non-controlling interests and have been adjusted to their approximate redemption values, after the attribution of net income or loss . Earnings per Share The Company’s capital structure includes common stock and unvested restricted stock awards. To compute earnings per share (“EPS”), the Company applies the two-class method because the Company’s unvested restricted stock awards are participating securities which are entitled to participate equally with the Company’s common stock in undistributed earnings. Application of the Company’s two-class method is as follows: (i) Net income attributable to the Company is reduced by the amount of dividends declared and by the contractual amount of dividends that must be paid for the current period for each class of stock, if any. (ii) The remaining undistributed net income of the Company is then equally allocated to its common stock and unvested restricted stock awards, as if all of the earnings for the period had been distributed. The total net income allocated to each security is determined by adding both distributed and undistributed net income for the period. (iii) The net income allocated to each security is then divided by the weighted average number of outstanding shares for the period to determine the EPS for each security considered in the two-class method. Cash and Cash Equivalents The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents are stated at cost which approximates fair value. Accounts Receivable Substantially all of the Company’s accounts receivable is related to providing healthcare services to patients. These services are paid for primarily by federal and state governmental authorities, managed care health plans, commercial insurance companies, workers’ compensation programs, and employer-directed programs. The Company’s general policy is to verify insurance coverage prior to the date of admission for patients admitted to its critical illness recovery hospitals and rehabilitation hospitals. Within the Company’s outpatient rehabilitation clinics, insurance coverage is verified prior to the patient’s visit. Within the Company’s Concentra centers, insurance coverage is verified or an authorization is received from the patient’s employer prior to the patient’s visit. The Company performs periodic assessments to determine if an allowance for expected credit losses is necessary. The Company considers its incurred loss experience and adjusts for known and expected events and other circumstances. In estimating its expected credit losses, the Company may consider changes in the length of time its receivables have been outstanding, changes in credit ratings for its payors, requests from payors to alter payment terms due to financial difficulty, and notices of payor bankruptcies or payors entering receivership. Because the Company’s accounts receivable is typically paid for by highly-solvent, creditworthy payors, such as Medicare, other governmental programs, and highly-regulated commercial insurers on behalf of the patient, the Company’s credit losses have been infrequent and insignificant in nature. Amounts recognized for allowances for expected credit losses are immaterial to the consolidated financial statements. Leases The Company evaluates whether a contract is or contains a lease at the inception of the contract. Upon lease commencement, the date on which a lessor makes the underlying asset available to the Company for use, the Company classifies the lease as either an operating or finance lease. Most of the Company’s facility leases are classified as operating leases. A right-of-use asset represents the Company’s right to use an underlying asset for the lease term while the lease liability represents an obligation to make lease payments arising from a lease. Right-of-use assets and lease liabilities are measured at the present value of the remaining fixed lease payments at lease commencement. As most of the Company’s leases do not specify an implicit rate, the Company uses its incremental borrowing rate, which coincides with the lease term at the commencement of a lease, in determining the present value of its remaining lease payments. The Company’s leases may also specify extension or termination clauses; these options are factored into the measurement of the lease liability when it is reasonably certain that the Company will exercise the option. Right-of-use assets also include any prepaid lease payments and initial direct costs, less any lease incentive received, at the lease commencement date. The Company has elected to account for lease and non-lease components, such as common area maintenance, as a single lease component for its facility leases. As a result, the fixed payments that would otherwise be allocated to the non-lease components are accounted for as lease payments and are included in the measurement of the Company’s right-of-use asset and lease liability. For the Company’s operating leases, lease expense, a component of cost of services and general and administrative expense in the consolidated statements of operations, is recognized on a straight-line basis over the lease term. For the Company’s finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization expense related to the right-of-use asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. The Company also makes variable lease payments which are expensed as incurred. These payments relate to changes in indexes or rates after the lease commencement date, as well as property taxes, insurance, and common area maintenance which were not fixed at lease commencement. This expense is a component of cost of services and general and administrative expense in the consolidated statements of operations. The Company may enter into arrangements to sublease portions of its facilities and the Company typically retains the obligation to the lessor under these arrangements. The Company’s subleases are classified as operating leases; accordingly, the Company continues to account for the original leases as it did prior to commencement of the subleases. Sublease income, a component of cost of services in the consolidated statements of operations, is recognized on a straight-line basis, as a reduction to lease expense, over the term of the sublease. The Company elected the short-term lease exemption for equipment leases; accordingly, equipment leases with terms of 12 months or less are not recorded in the consolidated balance sheets. For these leases, the Company recognizes lease payments on a straight-line basis over the lease term and variable lease payments are expensed as incurred. These expenses are included as components of cost of services in the consolidated statements of operations. Property and Equipment Property and equipment are stated at cost, net of accumulated depreciation. Maintenance and repairs of property and equipment are expensed as incurred. Improvements that increase the estimated useful life of an asset are capitalized. Direct internal and external costs of developing software for internal use, including programming and enhancements, are capitalized and depreciated over the estimated useful lives once the software is placed in service. Capitalized software costs are included within furniture and equipment. Software training costs, maintenance, and repairs are expensed as incurred. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the assets or the term of the lease, as appropriate. The general range of useful lives is as follows: Land improvements 5 – 25 years Leasehold improvements 1 – 20 years Buildings 40 years Building improvements 5 – 40 years Furniture and equipment 1 – 20 years The Company’s long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets or asset groups may not be recoverable. If the expected undiscounted future cash flows are less than the carrying amount of such assets or asset groups, the Company recognizes an impairment loss to the extent the carrying amount exceeds its estimated fair value. Intangible Assets Goodwill and indefinite-lived identifiable intangible assets Goodwill and other indefinite-lived intangible assets are recognized primarily as the result of business combinations. Goodwill is assigned to reporting units based upon the specific nature of the business acquired or, when a business combination contains business components related to more than one reporting unit, goodwill is assigned to each reporting unit based upon an allocation determined by the relative fair values of the business acquired. When the Company disposes of a business, the Company allocates a portion of the reporting unit’s goodwill to that business based on the relative fair values of the portion of the reporting unit being disposed of and the portion of the reporting unit remaining. The Company evaluates its reporting units on an annual basis and, if its reporting units are reorganized, the Company reassigns goodwill based on the relative fair values of the new reporting units. Goodwill and other indefinite-lived intangible assets are not amortized, but instead are subject to periodic impairment evaluations. The Company performs its impairment tests annually as of October 1 or when events or conditions occur that might suggest a possible impairment. Events or conditions which might suggest impairment could include a significant change in the business environment, the regulatory environment, or legal factors; a current period operating or cash flow loss combined with a history of such losses or a projection of continuing losses; or a sale or disposition of a significant portion of a reporting unit. The Company may first assess qualitatively whether goodwill is more likely than not impaired by considering relevant events or circumstances that affect the fair value or carrying amount of a reporting unit. If goodwill is more likely than not impaired, the Company is then required to complete a quantitative analysis. The Company considers both the income and market approach in determining the fair values of its reporting units when performing a quantitative analysis. If the carrying value of a reporting unit exceeds its fair value, an impairment charge is recognized equal to the difference between the carrying amount of the reporting unit and its fair value, not to exceed the carrying value of goodwill of the reporting unit. At December 31, 2021, the Company’s other indefinite-lived intangible assets consist of trademarks, certificates of need, and accreditations. To determine the fair values of its trademarks, the Company uses a relief from royalty income approach. For the Company’s certificates of need and accreditations, the Company performs qualitative assessments. As part of these assessments, the Company evaluates the current business environment, regulatory environment, legal and other company-specific factors. If it is more likely than not that the fair values are less than the carrying values, the Company performs a quantitative impairment test. The Company’s most recent impairment assessments were completed during the fourth quarter of 2021 utilizing information as of October 1, 2021. The Company did not identify any instances of impairment with respect to goodwill or other indefinite-lived intangible assets as of October 1, 2021. Finite-lived identifiable intangible assets Finite-lived intangible assets are amortized based on the pattern in which the economic benefits are consumed or otherwise depleted. If such a pattern cannot be reliably determined, finite-lived intangible assets are amortized on a straight-line basis over their estimated lives. Management believes that the below estimated useful lives are reasonable based on the economic factors applicable to each class of finite-lived intangible asset. The general range of useful lives is as follows: Customer relationships 5 – 15 years Non-compete agreements 1 – 15 years The Company’s finite-lived intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of those assets or asset groups may not be recoverable. If the expected undiscounted future cash flows are less than the carrying amount of such assets or asset groups, the Company recognizes an impairment loss to the extent the carrying amount exceeds its estimated fair value. Equity Method Investments The Company applies the equity method of accounting for investments in which the Company has the ability to exercise significant influence over the operating and financial policies of the investee, but does not possess a controlling financial interest in the investee. Investments of this nature are recorded at their original cost and adjusted periodically to recognize the Company’s share of its investees’ net income or losses after the date of investment. When net losses from an investment accounted for under the equity method exceed the carrying amount, the investment balance is reduced to zero. The Company resumes accounting for the investment under the equity method if the investee subsequently reports net income and the Company’s share of that net income exceeds the share of the net losses not recognized during the period the equity method was suspended. Investments are written down only when there is clear evidence that a decline in value that is other than temporary has occurred. The Company evaluates its equity method investments for impairment when there is evidence or indicators that a loss in value may be other than temporary. Income Taxes The Company recognizes deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s financial statements. Deferred tax assets and liabilities are determined on the basis of the differences between the book and tax bases of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company also recognizes the future tax benefits from net operating loss carryforwards as deferred tax assets. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company evaluates the realizability of deferred tax assets and reduces those assets using a valuation allowance if it is more likely than not that some portion or all of the deferred tax asset will not be realized. Among the factors used to assess the likelihood of realization are projections of future taxable income streams, the expected timing of the reversals of existing temporary differences, and the impact of tax planning strategies that could be implemented to avoid the potential loss of future tax benefits. Reserves for uncertain tax positions are established for exposure items related to various federal and state tax matters. Income tax reserves are recorded when an exposure is identified and when, in the opinion of management, it is more likely than not that a tax position will not be sustained and the amount of the liability can be estimated. Insurance Risk Programs Under a number of the Company’s insurance programs, which include the Company’s employee health insurance, workers’ compensation, and professional malpractice liability insurance programs, the Company is liable for a portion of its losses before it can attempt to recover from the applicable insurance carrier. The Company accrues for losses under an occurrence-based approach whereby the Company estimates the losses that will be incurred in a respective accounting period and accrues that estimated liability using actuarial methods. These programs are monitored quarterly and estimates are revised as necessary to take into account additional information. The Company also records insurance proceeds receivable for liabilities which exceed the Company’s deductibles and self-insured retention limits and are recoverable through its insurance policies. Revenue Recognition Patient Service Revenues Patient service revenues are recognized at an amount equal to the consideration the Company expects to be entitled to in exchange for providing healthcare services to its patients. Amounts owed for services provided are the obligations of the Company’s patients and can be paid for by third-party payors, including health insurers, government programs, and other payors on the patient’s behalf. Most of the Company’s patients are subject to healthcare coverage through a third-party payor arrangement. Given the nature and extent of third-party payor arrangements, the Company disaggregates its revenue by the following payor categories: Medicare : Medicare is a federal program that provides medical insurance benefits to persons age 65 and over, some disabled persons, and persons with end stage renal disease. The Company determines the transaction price for services provided to patients who are Medicare beneficiaries using Medicare’s prospective payment systems and other payment methods. The expected payment is determined by the level of clinical services provided and is sensitive to the patient’s length of stay. Non-Medicare : Non-Medicare payor sources include, but are not limited to, insurance companies (including Medicare Advantage plans), state Medicaid programs, workers’ compensation programs, health maintenance organizations, preferred provider organizations, other managed care companies and employers, as well as patients themselves. The transaction price for services provided to non-Medicare patients include amounts prescribed by state and federal fee schedules, negotiated contract amounts, or usual and customary amounts associated with the specific payor or based on the service provided. The Company applies the portfolio approach in determining revenues for certain homogeneous non-Medicare patient populations. The Company’s principal revenue source comes from providing healthcare services to patients. For patients treated within the Company’s outpatient rehabilitation clinics and Concentra centers, performance obligations are generally satisfied upon completion of the patient’s visit. For patients treated within the Company’s critical illness recovery and rehabilitation hospitals, the Company’s performance obligation is satisfied over the duration of the patient’s stay. As such, the Company recognizes revenue over the patient’s stay in amounts which are commensurate with the level of services provided to the patient. Any differences between the Company’s estimates of the transaction price, which may be impacted by various factors as described further below, and the payment received upon a patient’s discharge would be recognized as revenue in the period in which this change becomes known; such adjustments are not significant. The Company has an obligation to continue delivering treatment to patients admitted in the Company’s critical illness recovery and rehabilitation hospitals at the end of each reporting period. These performance obligations are typically satisfied in the subsequent month following the reporting period. The Company has elected the optional exemption which allows for the exclusion of disclosures regarding the transaction price allocated to unsatisfied performance obligations of contracts with a duration of less than one year. Revenue earned from providing services to patients is variable in nature, as the Company is required to make judgments which impact the transaction price, such as a patient’s condition and length of stay. These factors, among others, impact the payment the Company expects to receive for providing services. Variable consideration included in the transaction price is inclusive of the Company’s estimates of implicit discounts and other adjustments related to timely filing and documentation denials, out of network adjustments, and medical necessity denials, which are estimated using the Company’s historical experience. The Company is also subject to regular post-payment inquiries, investigations, and audits of the claims it submits for services provided. Some claims can take several years for resolution and may result in adjustments to the transaction price. Management includes in its estimates of the transaction price its expectations for these types of adjustments such that the amount of cumulative revenue recognized will not be subject to significant reversal in future periods. Historically, adjustments arising from a change in the transaction price have not been significant. Other Revenues The Company recognizes revenue for other services which principally consist of management and employee leasing services under contractual arrangements with related parties affiliated with the Company and non-affiliated healthcare institutions. The Company accounts for management and employee leasing services as single performance obligations satisfied over time. The transaction price is variable in nature and the Company recognizes revenue in amounts which are commensurate with the level of services provided during the period. The Company’s transaction price is determined such that the amount of cumulative revenue recognized will not be subject to significant reversal in future periods. Recently Adopted Accounting Guidance Reference Rate Reform In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2020-04, Reference Rate Reform (Topic 848), Facilitation of the Effects of Reference Rate Reform on Financial Reporting and in January 2021, the FASB issued 2021-01, Reference Rate Reform (Topic 848), Scope, which further clarified the scope of the reference rate reform optional practical expedients and exceptions outlined in Topic 848. Topic 848 provides temporary relief from some of the existing rules governing contract modifications when the modification is related to the replacement of the London Interbank Offered Rate (“LIBOR”) or other reference rates discontinued as a result of reference rate reform. On March 5, 2021, the Financial Conduct Authority (“FCA”) in the U.K. announced that all LIBOR settings will either cease to be provided or no longer be representative (i) immediately after December 31, 2021, in the case of the one-week and two-month USD LIBOR terms and all sterling, euro, Swiss franc and Japanese yen settings, and (ii) immediately after June 30, 2023, in the case of the one-, three-, six-, and 12-month USD LIBOR terms. For eligible contract modifications, the update generally allows an entity to account for and present modifications as an event that does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. That is, the modified contract is accounted for as a continuation of the existing contract. For cash flow hedging relationships affected by reference rate reform, Topic 848 provides expedients that allow an entity to (i) change the reference rate of either the forecasted transaction or hedging instrument due to reference rate reform without requiring dedesignation of the hedging relationship; (ii) assert that changes to the hedged forecasted transaction due to reference rate reform will not impact whether it remains probable of occurring; and (iii) for the purposes of assessment of hedge effectiveness assume that the reference rate will not be replaced for the remainder of the hedging relationship if both the hedged forecasted transaction and hedging instrument are expected to be impacted by reference rate reform. The standard was effective upon issuance on March 12, 2020, and the optional practical expedients can generally be applied to contract modifications made and hedging relationships entered into on or before December 31, 2022. Borrowings under the Company’s credit agreement bear interest, at the election of Select, based on LIBOR or an alternate base rate. The Company currently elects for its term loan borrowings to bear interest at a rate that is indexed to one-month LIBOR. Provisions within the credit agreement provide the Company with the ability to agree with JPMorgan Chase Bank, N.A., as administrative agent to the lenders, to replace LIBOR with a different reference rate in the event that LIBOR ceases to exist. The Company has not yet agreed upon a different reference rate with JPMorgan Chase Bank, N.A. For the Company’s cash flow hedge, which mitigates the Company’s exposure to increases in the one-month LIBOR rate above 1.0% on $2.0 billion of principal outstanding under the term loan, the Company has elected to assert that the hedged forecasted transaction remains probable of occurring, regardless of a modification or expected modification that may replace one-month LIBOR with a different reference rate. The Company intends to modify the cash flow hedge’s contractual terms related to the replacement of the reference rate, as necessary, to align with the reference rate specified for the Company’s term loan. For the purpose of the assessment of hedge effectiveness, the Company assumes that the reference rate will not be replaced for the remainder of the hedging relationship, as outlined by Topic 848. The Company’s cash flow hedge is described further in Note 12 – Interest Rate Cap. ASU 2020-04 has not had, and the Company does not expect it to have in future periods, a material impact on the Company's consolidated financial statements. Government Assistance In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832) , which requires business entities to disclose information about certain government assistance they receive if they account for the transactions by applying a grant or contribution model by analogy (for example, International Financial Reporting Standards (“IFRS”) guidance in International Accounting Standard (“IAS”) 20 or guidance on contributions for not-for-profit entities in Accounting Standards Codification (“ASC”) 958-605). For transactions in the scope of the new standard, business entities will need to provide information about the nature of the transaction and the accounting policy used, the significant terms and conditions associated with the transaction, and the amounts and financial statement line items affected by the transaction. The new guidance is effective for annual reporting periods beginning after December 15, 2021; however, early adoption is permitted. The disclosure requirements can be applied either prospectively or retrospectively. The Company early adopted ASU 2021-10 as of December 31, 2021. ASU 2021-10 did not have an impact on the Company's consolidated financial statements upon adoption. Recent Accounting Guidance Not Yet Adopted Convertible Instruments and Contracts on an Entity’s Own Equity In August 2020, the FASB issued ASU 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity. The ASU simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts on an entity’s own equity. As part of this update, convertible instruments are to be included in diluted earnings per share using the if-converted method, rather than the treasury stock method. Further, contracts which can be settled in cash or shares, excluding liability-classifie |
