Summary Of Significant Accounting Policies [Abstract] |
Nature Of Operations | NATURE OF OPERATIONS We operate through our two wholly-owned subsidiaries: VITAS Healthcare Corporation (“VITAS”) and Roto-Rooter Group, Inc. (“Roto-Rooter”). VITAS focuses on hospice care that helps make terminally ill patients' final days as comfortable as possible. Through its team of doctors, nurses, home health aides, social workers, clergy and volunteers, VITAS provides direct medical services to patients, as well as spiritual and emotional counseling to both patients and their families. Roto-Rooter provides plumbing, drain cleaning and water restoration services to both residential and commercial customers. Through its network of company-owned branches, independent contractors and franchisees, Roto-Rooter offers plumbing, drain cleaning service and water restoration to approximately 90% of the U.S. population.
Principles Of Accounting | PRINCIPLES OF ACCOUNTING The consolidated financial statements have been prepared on a going-concern basis. The consolidated financial statements include the accounts of Chemed Corporation and its wholly owned subsidiaries. All intercompany transactions have been eliminated. We have analyzed the provisions of the Financial Accounting Standards Board (“FASB”) authoritative guidance on the consolidation of variable interest entities relative to our contractual relationships with Roto-Rooter’s independent contractors and franchisees. The guidance requires the primary beneficiary of a Variable Interest Entity (“VIE”) to consolidate the accounts of the VIE. We have concluded that neither the independent contractors nor the franchisees are VIEs. Certain reclassifications have been made to prior year financial statements to conform to current presentation.
Cash Equivalents | CASH EQUIVALENTS Cash equivalents comprise short-term, highly liquid investments, including money market funds that have original maturities of three months or less.
Concentration Of Risk | CONCENTRATION OF RISK As of December 31, 2019 and 2018, approximately 71% and 68%, respectively, of VITAS’ total accounts receivable balance were from Medicare and 24% and 26%, respectively, of VITAS’ total accounts receivable balance were due from various state Medicaid or managed Medicaid programs. Combined accounts receivable from Medicare, Medicaid, and managed Medicaid represent approximately 75% of the consolidated net accounts receivable in the accompanying consolidated balance sheets as of December 31, 2019.
Inventories | INVENTORIES Substantially all of the inventories are either general merchandise or finished goods. Inventories are stated at the lower of cost or net realizable value. For determining the value of inventories, cost methods that reasonably approximate the first-in, first-out (“FIFO”) method are used.
Depreciation And Properties And Equipment | DEPRECIATION AND PROPERTIES AND EQUIPMENT Depreciation of properties and equipment is computed using the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the lesser of the remaining lease terms (excluding option terms) or their useful lives. Expenditures for maintenance, repairs, renewals and betterments that do not materially prolong the useful lives of the assets are expensed as incurred. The cost of property retired or sold and the related accumulated depreciation are removed from the accounts, and the resulting gain or loss is reflected currently in other operating expense or other income, net. Expenditures for major software purchases and software developed for internal use are capitalized and depreciated using the straight-line method over the estimated useful lives of the assets. For software developed for internal use, external direct costs for materials and services and certain internal payroll and related fringe benefit costs are capitalized in accordance with the FASB’s authoritative guidance on accounting for the costs of computer software developed or obtained for internal use. The weighted average lives of our property and equipment at December 31, 2019, were:
Buildings and building improvements | 15.1 | yrs.
Transportation equipment | 4.6 |
Machinery and equipment | 5.2 |
Computer software | 4.2 |
Furniture and fixtures | 4.6 |
Goodwill And Intangible Assets | GOODWILL AND INTANGIBLE ASSETS The table below shows a rollforward of Goodwill (in thousands):
|  |  |  |  | Roto- |  |  |
|  | Vitas |  | Rooter |  | Total
Balance at December 31, 2017 |  | $ | 328,301 |  | $ | 148,586 |  | $ | 476,887
Business combinations |  |  | 5,030 |  |  | 28,780 |  |  | 33,810
Foreign currency adjustments |  |  | - |  |  | (127) |  |  | (127)
Balance at December 31, 2018 |  | $ | 333,331 |  | $ | 177,239 |  | $ | 510,570
Business combinations |  |  | - |  |  | 66,726 |  |  | 66,726
Foreign currency adjustments |  |  | - |  |  | 71 |  |  | 71
Balance at December 31, 2019 |  | $ | 333,331 |  | $ | 244,036 |  | $ | 577,367
Identifiable, definite-lived intangible assets arise from purchase business combinations and are amortized using either an accelerated method or the straight-line method over the estimated useful lives of the assets. The selection of an amortization method is based on which method best reflects the economic pattern of usage of the asset. Reacquired franchise rights are amortized over the remaining term of the franchise agreement at the time of acquisition. The weighted average lives of our identifiable, definite-lived intangible assets at December 31, 2019, were:
Covenants not to compete | 6.4 | yrs.
Reacquired franchise rights | 7.4 |
Referral networks | 10.0 |
Customer lists | 16.8 |
The date of our annual goodwill and indefinite-lived intangible asset impairment analysis is October 1. The VITAS trade name is considered to have an indefinite life. We also capitalize the direct costs of obtaining licenses to operate either hospice programs or plumbing operations subject to a minimum capitalization threshold. These costs are amortized over the life of the license using the straight-line method. Certificates of Need (“CON”), which are required in certain states for hospice operations, are generally granted without expiration and thus, we believe them to be indefinite-lived assets subject to impairment testing. We consider that Roto-Rooter Corp. (“RRC”), Roto-Rooter Services Co. (“RRSC”) and VITAS are appropriate reporting units for testing goodwill impairment. We consider RRC and RRSC separate reporting units but one operating segment. This is appropriate as they each have their own set of general ledger accounts that can be analyzed at “one level below an operating segment” per the definition of a reporting unit in FASB guidance. We completed our qualitative analysis for impairment of goodwill and our indefinite-lived intangible assets as of October 1, 2019. Based on our assessment, we do not believe that it is more likely than not that our reporting units or indefinite-lived assets fair values are less than their carrying values.
Long-Lived Assets | LONG-LIVED ASSETS If we believe a triggering event may have occurred that indicates a possible impairment of our long-lived assets, we perform an estimate and valuation of the future benefits of our long-lived assets (other than goodwill, the VITAS trade name and capitalized CON costs) based on key financial indicators. If the projected undiscounted cash flows of a major business unit indicate that properties and equipment or identifiable, definite-lived intangible assets have been impaired, a write-down to fair value is made.
Lease Accounting | LEASE ACCOUNTING In February 2016, the FASB issued Accounting Standards Update “ASU No. 2016-02 Leases” which introduced a lessee model that brings most leases onto the balance sheet and updates lessor accounting to align with changes in the lessee model and the revenue recognition standard. This standard is also referred to as Accountings Standards Codification No.842 (“ASC 842”). We adopted ASC 842 effective January 1, 2019, using the optional transition method requiring leases existing at, or entered into January 1, 2019 to be recognized and measured. The transition method selected does not require adjustments to prior period amounts, which continue to be reflected in accordance with historical accounting. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard which, among other things, allowed us to carry forward the historical lease classification. Chemed and each of its operating subsidiaries are service companies. As such, real estate leases comprise the largest lease obligation (and conversely, right of use asset) in our lease portfolio. VITAS has leased office space, as well as space for inpatient units (“IPUs”) and/or contract beds within hospitals. Roto-Rooter mainly has leased office space. Roto-Rooter purchases equipment and leases it to certain of its independent contractors. We analyzed these leases in accordance with ASC 842 and determined they are operating leases. As a result, Roto-Rooter will continue to capitalize the equipment underlying these leases, depreciate the equipment and recognize rental income. Adoption of the new standard resulted in right of use assets and lease liabilities of $93.1 million and $104.3 million, respectively, as January 1, 2019. In determining the liability, we used our incremental borrowing rate based on the information available at the time of adoption, since the rate implicit in the leases cannot be readily determined. At January 1, 2019, the weighted average rate was 3.47%. The standard did not materially impact our consolidated net income or cash flows. We did not book a cumulative effect adjustment upon adoption of the standard.
Cloud Computing | CLOUD COMPUTING On January 1, 2019, we early adopted ASU No. 2018-15, “Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract”. This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software. We adopted the ASU on a prospective basis. As of December 31, 2019, we have two cloud computing arrangements that are service contracts. Roto-Rooter is implementing a system to assist in technician dispatch and VITAS is implementing a new human resources system. We have capitalized approximately $5.7 million related to implementation of these projects which are included in prepaid assets in the accompanying balance sheets. There has been no amortization expense associated with the assets, as the software has not yet been placed in service. We anticipate amortizing the assets over the original term of the arrangements plus renewal options that are reasonably certain of being exercised.
Other Assets | OTHER ASSETS Debt issuance costs are included in other assets. Issuance costs related to revolving credit agreements are amortized using the straight-line method, over the life of the agreement. All other issuance costs are amortized using the effective interest method over the life of the debt. There are no amounts included in other assets that individually exceed 5% of total assets.
Sales Tax | SALES TAX The Roto-Rooter segment collects sales tax from customers when required by state and federal laws. We record the amount of sales tax collected net in the accompanying consolidated statements of income.
Operating Expenses | OPERATING EXPENSES Cost of services provided and goods sold (excluding depreciation) includes salaries, wages and benefits of service providers and field personnel, material costs, medical supplies and equipment, pharmaceuticals, insurance costs, service vehicle costs and other expenses directly related to providing service revenues or generating sales. Selling, general and administrative expenses include salaries, wages, stock-based compensation expense and benefits of selling, marketing and administrative employees, advertising expenses, communications and branch telephone expenses, office rent and operating costs, legal, banking and professional fees and other administrative costs. The cost associated with VITAS sales personnel is included in cost of services provided and goods sold (excluding depreciation).
Advertising | ADVERTISING We expense the production costs of advertising the first time the advertising takes place. We pay for and expense the cost of internet advertising and placement on a “per click” basis. Similarly, the majority of our telephone directory listings are paid for and expensed on a “cost per call” basis. For those directories that are not on this billing basis, the cost of the directory is expensed when the directories are placed in circulation. Advertising expense for the year ended December 31, 2019, was $49.5 million (2018 – $47.0 million; 2017 - $40.9 million).
Other Current Liabilities | OTHER CURRENT LIABILITIES There are no amounts included in other current liabilities that individually exceed 5% of total current liabilities, with the exception of , the Medicare cap liability, which is discussed further in Footnote 2.
Other Liabilities (Non-Current) | OTHER LIABILITIES (NON-CURRENT) There are no amounts included in other liabilities that individually exceed 5% of total liabilities.
Stock-Based Compensation Plans | STOCK-BASED COMPENSATION PLANS Stock-based compensation cost is measured at the grant date, based on the fair value of the award and recognized as expense over the employee’s requisite service period on a straight-line basis.
Non-Employee Stock Compensation | NON-EMPLOYEE STOCK COMPENSATION In June 2018, the FASB issued Accounting Standards Update “ASU No. 2018-07 – Compensation – Stock Compensation”. The ASU expands the scope of current guidance to include all share-based payment arrangements related to the acquisition of goods and services from both non-employees and employees. The guidance in the ASU is effective for the Company in all fiscal years beginning after December 15, 2018. Adoption of this standard had no material impact on our Consolidated Financial Statements.
Insurance Accruals | I NSURANCE ACCRUALS For our Roto-Rooter segment and Corporate Office, we initially self-insure for all casualty insurance claims (workers’ compensation, auto liability and general liability). As a result, we closely monitor and frequently evaluate our historical claims experience to estimate the appropriate level of accrual for self-insured claims. Our third-party administrator (“TPA”) processes and reviews claims on a monthly basis. Currently, our exposure on any single claim is capped by stop-loss coverage at $750,000. In developing our estimates, we accumulate historical claims data for the previous 10 years to calculate loss development factors (“LDF”) by insurance coverage type. LDFs are applied to known claims to estimate the ultimate potential liability for known and unknown claims for each open policy year. LDFs are updated annually. Because this methodology relies heavily on historical claims data, the key risk is whether the historical claims are an accurate predictor of future claims exposure. The risk also exists that certain claims have been incurred and not reported on a timely basis. To mitigate these risks, in conjunction with our TPA, we closely monitor claims to ensure timely accumulation of data and compare claims trends with the industry experience of our TPA. For the VITAS segment, we initially self-insure for workers’ compensation claims. Currently, VITAS’ exposure on any single claim is capped by stop-loss coverage at $1,000,000. For VITAS’ self-insurance accruals for workers’ compensation, the valuation methods used are similar to those used internally for our other business units. We are also insured for other risks with respect to professional liability with a deductible of $750,000. Our casualty insurance liabilities are recorded gross before any estimated recovery for amounts exceeding our stop loss limits. Estimated recoveries from insurance carriers are recorded as accounts receivable. Claims experience adjustments to our casualty and workers’ compensation accrual for the years ended December 31, 2019, 2018 and 2017, were net pretax credits of ($1,664,000), ($3,437,000), and ($1,800,000) respectively.
Taxes On Income | TAXES ON INCOME On December 22, 2017, the President of the United States signed into law H.R.1, “An Act to Provide for Reconciliation Pursuant to Titles II and V of the Concurrent Resolution on the Budget for Fiscal Year 2018” (previously known as “The Tax Cuts and Jobs Act”) or (the “Act”). The Act amends the Internal Revenue Code to reduce tax rates and modify policies, credits, and deductions for individuals and businesses. For businesses, U.S. generally accepted accounting principles requires resulting tax effects for the Act, to be recorded in the reporting period of enactment. The SEC issued SAB 118, which provides guidance on accounting for the Act’s impact. Under SAB 118, an entity would use something similar to the measurement period in a business combination, not to exceed one year. For matters that have not been completed, the Company would recognize provisional amounts to the extent that they are reasonably estimable, adjust them over time as more information becomes available, and disclose this information in its financial statements. Our accounting for all elements of the Tax Act is complete. The Company did not record any material changes to the provisional amounts previously recorded, net benefit recorded in 2017 of $8.3 million. The Company also determined new rules, such as the Global Intangible Low-Taxed Income (GILTI) and Base Erosion and Anti-Abuse Tax (BEAT), have no material impact to the financial statements. Historically, the Company has not provided for deferred taxes on undistributed earnings because such earnings are considered to be indefinitely reinvested outside of the U.S. The Company continues this assertion that foreign earnings are permanently reinvested under the Act. The Act provides for 100 percent bonus depreciation on personal tangible property expenditures starting September 27, 2017 through 2022. The bonus depreciation percentage is phased down from 100 percent beginning in 2023 through 2026. The Company expects to take full benefit of these bonus depreciation rules. The IRS and other tax authorities are still issuing guidance on the Act, through various regulations some of which are still proposed and not final. The Company will implement any changes related to finalized regulations and other guidance in the period issued. Deferred taxes are provided on an asset and liability method whereby deferred tax assets are recognized for deductible temporary differences and operating loss carryforwards and deferred tax liabilities are recognized for taxable temporary differences. Temporary differences are the differences between the reported amount of assets and liabilities and their tax basis. Deferred tax assets are reduced by a valuation allowance when, in our opinion, it is more likely than not that some portion or all of the deferred tax assets will not be realized due to insufficient taxable income within the carryback or carryforward period available under the tax laws. Deferred tax assets and liabilities are adjusted for the effects of changes in law and rates on the date of enactment. We are subject to income taxes in Canada, U.S. federal and most state jurisdictions. Judgement is required to determine our provision for income taxes. Our financial statements reflect expected future tax consequences of such uncertain positions assuming the taxing authorities’ full knowledge of the position and all relevant facts.
Contingencies | CONTINGENCIES As discussed in Note 17, we are subject to various lawsuits and claims in the normal course of our business. In addition, we periodically receive communications from governmental and regulatory agencies concerning compliance with Medicare and Medicaid billing requirements at our VITAS subsidiary. We establish reserves for specific, uninsured liabilities in connection with regulatory and legal action that we deem to be probable and reasonably estimable. We record legal fees associated with legal and regulatory actions as the costs are incurred. We disclose material loss contingencies that are probable but not reasonably estimable and those that are at least reasonably possible.
Business Combinations | BUSINESS COMBINATIONS We account for acquired businesses using the acquisition method of accounting. All assets acquired and liabilities assumed are recorded at their respective fair values at the date of acquisition. The determination of fair value involves estimates and the use of valuation techniques when market value is not readily available. We use various techniques to determine fair value in accordance with accepted valuation models, primarily the income approach. The significant assumptions used in developing fair values include, but are not limited to, revenue growth rates, the amount and timing of future cash flows, discount rates, useful lives, royalty rates and future tax rates. The excess of purchase price over the fair value of assets and liabilities acquired is recorded as goodwill. See Footnote 7 for discussion of recent acquisitions.
Estimates | ESTIMATES The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States requires us to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Disclosures of after-tax expenses and adjustments are based on estimates of the effective income tax rates for the applicable segments.
