Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying financial statements have been prepared in accordance with U.S. GAAP and pursuant to the rules and regulations of the SEC. In the opinion of management, all adjustments, consisting of only normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows have been made. Reporting Currency All values are in U.S. dollars ($ or "USD") unless specifically indicated otherwise. Basis of Consolidation These consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions have been eliminated. Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Management bases these estimates and assumptions upon historical experience, existing and known circumstances, authoritative accounting pronouncements and other factors that management believes to be reasonable. Areas requiring the use of management estimates relate to revenue recognition, accounts receivable and the related allowance for doubtful accounts, income tax provisions, and fair value of financial instruments. Actual results could differ from these estimates. Segment Reporting The Company’s chief operating decision-makers ("CODMs") are its Chief Executive Officer and Chief Operating Officer, who make resource allocation decisions and assess performance based on financial information presented on an aggregate basis. There are no segment managers who are held accountable by the chief operating decision-makers, or anyone else, for any planning, strategy and key decision-making regarding operations. The corporate office is responsible for contract negotiation with vendors and payors, corporate compliance with healthcare laws and regulations, and revenue cycle management, among other corporate supporting functions. Accordingly, the Company has a single reportable segment and operating segment structure based on ASC 280, Segment Reporting . Cash and Cash Equivalents Cash and cash equivalents consist of cash and temporary investments with an original maturity of three months or less that are readily convertible to known amounts of cash that are subject to insignificant risk or change. At December 31, 2022 and 2021, the Company's cash was held primarily in checking and money market accounts. Cash and cash equivalents consist of the following at December 31, 2022 and 2021: December 31, 2022 December 31, 2021 Cash $ 5,910 $ 11,952 Money market accounts 11,004 16,456 Total cash and cash equivalents $ 16,914 $ 28,408 Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are regularly reviewed for collectability and an allowance is recorded to cover the estimated bad debts and billing modifications. The accounts receivable are presented on the Consolidated Balance Sheets net of the allowance for doubtful accounts. It is possible that the estimates of the allowance for doubtful accounts could change, which could have a material impact on our operations and cash flows. The Company writes off receivables when the likelihood for collection is remote, and when the Company believes collection efforts have been fully exhausted and it does not intend to devote additional resources in attempting to collect. The write-offs are charged against the allowance for doubtful accounts. For the year ended December 31, 2022, the Company's evaluation takes into consideration such factors as historical bad debt and billing modification experience, national and local economic trends and conditions, industry and regulatory conditions, other collection indicators and information about disaggregated receivables. The complexity of many third-party billing arrangements, patient qualification for medical necessity of equipment and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. The estimates and charge-offs for the allowance for doubtful accounts for each reporting period were as follows: December 31, 2022 December 31, 2021 Balance, beginning of year $ 7,031 $ 9,013 Provision for uncollectible accounts 10,011 6,895 Amounts written off (8,559) (8,877) Balance, end of period $ 8,483 $ 7,031 Included in accounts receivable at December 31, 2022 are amounts due from Medicare and Medicaid representing 38% and 10%, respectively, and 48% combined, of total outstanding receivables. As of December 31, 2021, 44% of total outstanding receivables were amounts due from Medicare and Medicaid. Revenues from Medicare and Medicaid as percentages of the Company's traditional revenue streams, excluding COVID-19 response sales and services, for the years ended December 31, 2022 and 2021 were as follows: Year Ended December 31, 2022 2021 Medicare revenues 47 % 55 % Medicaid revenues 9 % 9 % Total Medicare and Medicaid revenues 56 % 64 % Inventory Inventory represents non-serialized supplies that consist of equipment parts, consumables, and associated product supplies and is expensed at the time of sale or use. The Company values inventory at the lower of cost or net realizable value. Obsolete and unserviceable inventories are valued at estimated net realizable value. Inventory is presented net of a reserve balance of nil and $1,418,000 at December 31, 2022 and 2021, respectively, that relates to COVID-19 response supplies. During the year ended December 31, 2022, these supplies were determined to be unavailable for sale due to expiration. Accordingly, the previously established inventory reserves were eliminated upon disposal. Property and Equipment Property and equipment is presented on the Consolidated Balance Sheets at historic cost less accumulated depreciation. Major renewals and improvements that extend the useful life of assets are capitalized to the respective property accounts, while maintenance and repairs, which do not extend the useful life of the respective assets, are expensed as incurred. Management has estimated the useful lives of equipment leased to customers. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets. The estimated useful lives of the property and equipment are as follows: Description Estimated Useful Lives Medical Equipment 1 - 10 Years Computer Equipment 5 Years Office Furniture & Fixtures 5 - 10 Years Leasehold Improvements Shorter of Useful Life or Lease Vehicles 5 Years Buildings 15 - 39 Years Land Indefinite Life Depreciation of medical equipment commences at the date of service, which represents the date that the asset has been delivered to a patient and is put in use and continues through the useful life of the asset. Property and equipment with definite useful lives are tested for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. Prepaid Expenses and Other Assets Prepaid expenses and other current assets includes amounts due from Medicare Administrative Contractors ("MACs") as a result of successful appeals and prepaid expenses such as insurance and rent. Equity Investments Equity investments on the Consolidated Balance Sheets are comprised of an investment accounted for under the equity method and equity investments without readily determinable fair values accounted for under the measurement alternative described in ASC 321-10-35-2. The following table details the Company’s equity investments: December 31, 2022 December 31, 2021 Equity method investments $ 816 $ 959 Other equity investments 1,339 1,198 Balance, end of period $ 2,155 $ 2,157 The Company's equity method investments include a 49% equity interest in Solvet Services, LLC, an entity which provides health care support services to state and federal governments. Investments accounted for under the equity method are investments in unconsolidated entities over whose operating and financial policies the Company has the ability to exercise significant influence but not control. Equity method investments are initially measured at cost in the Consolidated Balance Sheets with a n y subsequent adjustments made to the carrying amount of the investment for the Company’s proportionate share of income or loss. The Company has recognized its share of income or loss on the gain (loss) from equity method investments within non-operating expenses in the Consolidated Statements of Income. Equity method investments are evaluated for impairment whenever events or changes in circumstances indicate that the carrying value of the investments may exceed the fair value. No events or changes have occurred as of December 31, 2022 that would impair the carrying value of equity method investments. Other equity investments include an equity interest in VeruStat, Inc, a remote patient monitoring entity, and an equity interest in DMEscripts, LLC, an e-prescribing platform. Other equity investments are investments without a readily determinable fair value which do not qualify for the practical expedient in ASC 820. For these investments, the Company has elected the measurement alternative which measures the investment at cost, less any impairment. ASU 2019-04 clarifies that if an entity identifies observable price changes in orderly transactions for the identical or a similar investment of the same issuer, it must measure its equity investment at fair value in accordance with ASC 820 as of the date that the observable transaction occurred. The Company was not aware of any impairment or observable price change adjustments that needed to be made as of December 31, 2022 on its investments in equity securities without a readily determinable fair value. Debt Investment The Company's debt investment is a variable rate secured convertible note issued by Healthcare DX, Inc. (d/b/a ModoHealth) on December 21, 2022, classified as an available-for-sale debt instrument. Accrued interest is due upon the 18 month maturity of the note and is included in the amortized cost basis at each reporting period. At each financial statement date until a conversion event, the debt instrument is required to be remeasured at fair value. Changes in unrealized gains and losses are included in accumulated other comprehensive income, net of tax effect, until realized. Comprehensive Income Comprehensive income reflects the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. The Company's comprehensive income represents net income adjusted for unrealized gains and losses on derivative instruments, net of tax. Accumulated other comprehensive loss is presented on the accompanying Consolidated Balance Sheets as a component of shareholders' equity. As a result of the “backward tracing” prohibition in ASC 740, certain previously measured unrealized gains or losses have resulted in the existence of "dangling" amounts within other comprehensive income. The Company has elected the individual security approach to the release of these effects. Under the individual security approach, dangling amounts are tracked on a security-by-security basis and cleared out of the other comprehensive income balance upon sale of each individual security. During the year ended December 31, 2022, the underlying securities associated with a dangling balance were settled and the associated balances were recognized as a current tax expense. Revenue Recognition Revenue from a customer consists of sales and rentals of home medical equipment and medical services. Patient revenues are billed to and collections received from Medicare, Medicaid, third-party insurers, co-insurance and patient-pay. Patient revenue is recognized net of contractual adjustments and bad debt based on contractual arrangements with third-party payors, an evaluation of expected collections resulting from the analysis of current and past due accounts, past collection experience in relation to amounts billed and other relevant information. Contractual adjustments result from the differences between the rates charged for services and reimbursement rates paid by government-sponsored healthcare programs and insurance companies for such services. The Company's contracts with customers often include multiple products and services, and the Company evaluates these arrangements to determine the unit of accounting for revenue recognition purposes based on whether the product or service is distinct from other products or services in the arrangement and should be accounted for as a separate performance obligation. A product or service is distinct if the customer can benefit from it on its own or together with other readily available resources and the Company's ability to transfer the goods or services is separately identifiable from other promises in the contractual arrangement with the customer (e.g. patient). Revenue is then allocated to each separately identifiable good or service based on the standalone price of the items underlying the performance obligations. Most of the Company’s products fall in the Medicare FFS program which is a payment model where services are unbundled and paid for separately. These services are paid based on a Medicare determined price that is publicly available on the website for CMS. For commercial payors, DME companies must negotiate in-network pricing separately, though in general, the Company’s payors tend to benchmark their contract rates and coverage policies closely to those of Medicare. The Company considers performance obligations for sales and rentals to be met when the customer receives the equipment, and revenue for rentals is recognized over time, over the respective rental period. For revenue associated with HME rentals, the Company recognizes revenue in accordance with FASB ASC 842, “Leases,” (Topic 842). For any HME sales and services, the Company recognizes revenue under FASB ASU 2014-09, “Revenue from Contracts with Customers,” (Topic 606) and related amendments. The Company recognizes equipment rental revenue over the non-cancelable lease term, which varies based on the type of equipment rental, less estimated adjustments, in accordance with Topic 842. The Company has separate contracts with each patient that are not subject to a master lease agreement with any third-party payor. The Company would first consider the lease classification issue (sales-type lease or operating lease) and then appropriately recognize or defer rental revenue over the lease term . Revenues associated with external staffing services are accrued on an hourly basis and are recorded based on the determination of whether the Company is acting as a principal or an agent. In arrangements in which the Company manages customers' supplemental workforce needs utilizing its own network of healthcare professionals, the Company is determined to be a principal and includes the contractual gross billings in revenues with a corresponding increase to cost of revenues for worksite employee payroll costs associated with these services. Alternatively, when the Company acts as agent in the performance of workforce management, revenue is recorded based on contractually agreed upon fees or commissions with no associated cost of revenues. The revenues from each major source are summarized in the following table: Year Ended December 31, 2022 2021 Revenue from rentals under Topic 842 Ventilator rentals, non-invasive and invasive $ 92,710 $ 83,849 Other durable medical equipment rentals 21,446 13,843 Revenue from sales and services under Topic 606 Equipment and supply sales 13,927 8,765 COVID-19 response sales and services 2,278 8,558 Service revenues 8,471 2,047 Total revenues $ 138,832 $ 117,062 Revenue Accounting under Topic 842 The Company leases HME such as non-invasive and invasive ventilators, PAP machines, percussion vests, oxygen concentrator units and other small respiratory equipment to customers for a fixed monthly amount on a month-to-month basis. The customer generally has the right to cancel the lease at any time during the rental period. The Company considers these rentals to be operating leases. Under FASB Accounting Standards Codification Topic 842, the Company recognizes rental revenue on operating leases on a straight-line basis over the contractual lease term which varies based on the type of equipment rental. The lease term begins on the date equipment is delivered to patients, and revenues are recorded at amounts estimated to be received under reimbursement arrangements with third-party payors, including Medicare, private commercial payors, and Medicaid. Certain customer co-payments are included in revenue when considered probable of payment, which is generally when paid. Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenue and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. Such adjustments are typically identified and recorded at the point of cash application or claim denial. Revenue Accounting under Topic 606 The Company sells HME, replacement parts and supplies to customers and recognizes revenue based on contractual payment rates as determined by the payors at the point in time where control of the good or service is transferred through delivery to the customer. The customer and, if applicable, the payors are generally charged at the time that the product is sold. For sales of equipment previously placed in service, proceeds associated with these sales are recorded to gain (loss) on disposal of property and equipment. The Company also provides sleep study services to customers and recognizes revenue when the sleep study results are complete, satisfying the performance obligation. In response to the COVID-19 pandemic, the Company began offering contact tracing services, which revenues are recognized in the period in which the service has been provided. The transaction price on equipment sales, sleep studies, and contact tracing is the amount that the Company expects to receive in exchange for the goods and services provided. Due to the nature of the HME business, gross charges are retail charges and generally do not reflect what the Company is ultimately paid. As such, the transaction price is constrained for the difference between the gross charge and what is estimated to be collected from payors and from patients. The transaction price therefore is predominantly based on contractual payment rates as determined by the payors. The payment terms and conditions of customer contracts vary by customer type and the products and services offered. For staffing services, performance obligations in the staffing agreements are satisfied over time when the customer simultaneously receives and consumes the benefits provided. Accordingly, revenues from staffing services are recognized on an hourly basis as services are rendered by the job site employee in both principal and agent arrangements. The Company determines its estimates of contractual allowances and discounts based upon contractual agreements, its policies and historical experience. While the rates are fixed for the product or service with the customer and the payors, such amounts typically include co-payments, co-insurance and deductibles, which vary in amounts, and are due from the patient. The Company includes in the transaction price only the amount that the Company expects to be entitled, which is substantially all of the payor billings at contractual rates. The transaction price is initially constrained by the amount of customer co-payments, which are included in the transaction price when considered probable of payment and included in revenue if the product or service has already been provided to the customer. Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenue and accounts receivable at their net realizable values. Inherent in these estimates is the risk that they will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payors may result in adjustments to amounts originally recorded. Such adjustments are typically identified and recorded at the point of cash application or claim denial. Returns and refunds are not accepted on equipment sales, sleep study services, staffing services, or contact tracing services. The Company does not offer warranties to customers in excess of the manufacturer’s warranty. Any taxes due upon sale of the products or services are not recognized as revenue. The Company does not have any partially or unfilled performance obligations related to contracts with customers and as such, the Company has no contract liabilities as of December 31, 2022 or 2021. Stock-Based Compensation The Company accounts for its stock-based compensation in accordance with ASC 718 , "Compensation—Stock Compensation" , which establishes accounting for share-based awards exchanged for employee services and requires companies to expense the estimated fair value of these awards over the requisite employee service period. Stock–based compensation costs for stock options are determined at the grant date using the Black-Scholes option pricing model. Stock-based compensation costs for RSUs are determined at the grant date based on the closing stock price. The expense of such stock-based compensation awards is recognized using the graded vesting attribution method over the vesting period and the offsetting credit is recorded as an increase in additional paid-in capital. Forfeitures are recorded as incurred. Any excess tax benefit or deficiency is recognized as a component of income taxes and within operating cash flows upon vesting of the share-based award. For the Company’s phantom share units settled in cash, the Company computes the fair value of the phantom share units using the closing price of the Company's stock at the end of each period and records a liability based on the percentage of requisite service. Interest Rate Swaps The Company utilized an interest rate swap contract to reduce exposure to fluctuations in variable interest rates for future interest payments on the 2019 Term Note (as defined below). For determining the fair value of the interest rate swap contract, the Company uses significant other observable market data or assumptions (Level 2 inputs) that market participants would use in pricing similar assets or liabilities, including assumptions about counterparty risk. These fair value estimates reflect an income approach based on the terms of the interest rate swap contract and inputs corroborated by observable market data including interest rate curves. The Company presents a positive ending period fair value of the interest rate swap contract in other long-term assets, as a component of long-term assets, and a negative ending period fair value of the interest rate swap contract in accrued liabilities, as a component of long-term liabilities on the Consolidated Balance Sheets. The Company recognized any differences between the variable interest rate payments and the fixed interest rate settlements from its swap counterparty as an adjustment to interest expense over the life of the swap. If determined to be an effective cash flow hedge, the Company will record the changes in the estimated fair value of the swaps to accumulated other comprehensive income or loss on the Consolidated Balance Sheets. To the extent that interest rate swaps are determined to be ineffective, the Company would recognize the changes in the estimated fair value of swaps in interest and other non-operating expenses, net in its Consolidated Statements of Income. During the year ended December 31, 2022, the Company settled its interest rate swap in connection with the refinancing of its credit facilities and recognized the realized gain of $0.2 million in Other Income. Income Taxes The Company is subject to income taxes in numerous U.S. jurisdictions. Significant judgment is required in determining the provision for income taxes. The Company’s income tax provisions reflect management’s interpretation of country and state tax laws. There are many transactions and calculations for which the ultimate tax determination is uncertain during the ordinary course of business and may remain uncertain for several years after their occurrence. The Company recognizes assets and liabilities for taxation when it is probable that the Company will receive refunds or pay taxes to the relevant tax authority. Where the final determination of tax assets and liabilities is different from the amounts that were initially recorded, such differences will impact the current and deferred income taxes provision in the period in which such determination is made. Changes in tax law or changes in the way tax law is interpreted may also impact the Company’s effective tax rate as well as its business and operations. Income tax expense consists of current and deferred tax expense. Current and deferred tax are recognized in profit or loss except to the extent that it relates to items recognized directly in equity or other comprehensive income. Current tax is recognized and measured at the amount expected to be recovered from or payable to the taxation authorities based on the income tax rates enacted at the end of the reporting period and includes any adjustment to taxes payable in respect of previous years. Deferred income tax assets and liabilities are recognized for the future income tax consequences attributable to temporary differences between the financial statement carrying value of assets and liabilities and their respective income tax bases. Deferred income tax assets or liabilities are measured using enacted income tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be settled. The calculation of current and deferred income taxes requires management to make estimates and assumptions and to exercise a certain amount of judgment concerning the carrying value of assets and liabilities. The current and deferred income tax assets and liabilities are also impacted by expectations about future operating results and the timing of reversal of temporary differences as well as possible audits of tax filings by regulatory agencies. Changes or differences in these estimates or assumptions may result in changes to the current and deferred tax assets and liabilities on the Consolidated Balance Sheets and a charge to or recovery of income tax expense. Deferred tax is recognized on any temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases used in the computation of taxable earnings. The effect of a change in the enacted tax rates is recognized in net earnings and comprehensive income or in equity depending on the item to which the adjustment relates. At each reporting period end, deferred tax assets are evaluated for recoverability based on whether it is more likely than not that sufficient taxable earnings will be available to allow all or part of the asset to be recovered. See Note 10 for details on income taxes recognized. Impairment of Long-Lived Assets The Company follows ASC Topic 360, which requires that long-lived assets be reviewed for impairment whenever events or changes in circumstances indicate that the asset group’s carrying amounts may not be recoverable. In performing the review for recoverability, if future undiscounted cash flows (excluding interest charges) from the use and ultimate disposition of the assets are less than their carrying values, an impairment loss represented by the difference between its fair value and carrying value, is recognized. When properties are classified as held for sale they are recorded at the lower of the carrying amount or the expected sales price less costs to sell. There were no impairment charges recognized during the years ended December 31, 2022 and 2021. Net Income per Share Attributable to Common Stockholders Basic net income per common share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted net income per common share is computed based on the weighted average number of shares of common stock plus the effect of dilutive stock-based awards outstanding during the period using the treasury stock method. Dilutive stock-based awards include outstanding common stock options and time-based RSUs. See Note 11 for earnings per share computations. Recently Adopted Accounting Pronouncements In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). ASU 2019-12 removes certain exceptions for performing intraperiod tax allocations, recognizing deferred taxes for investments, and calculating income taxes in interim periods. The guidance also simplifies the accounting for franchise taxes, transactions that result in a step-up in the tax basis of goodwill, and the effect of enacted changes in tax laws or rates in interim periods. The Company adopted ASU 2019-12 in the first quarter of 2021 and the adoption had no material impact to the Company’s consolidated financial statements. On January 1, 2021, the Company adopted Accounting Standards Update (ASU) No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815) (ASU 2020-01), which clarifies the interaction of the accounting for equity securities under Topic 321, the accounting for equity method investments in Topic 323, and the accounting for certain forward contracts and purchased options in Topic 815. The adoption of this new standard did not have a material impact on our consolidated financial statements. On January 1, 2023, the Company adopted ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, The standard replaces the current incurred loss impairment model that recognizes losses when a probable threshold is met with a requirement to recognize lifetime expected credit losses immediately when a financial asset is originated or purchased. Further, the FASB issued ASU 2019-04 and ASU 2019-05 to provide additional guidance on the credit losses standard. While the adoption of ASC 326 could result in a higher allowance for credit losses on receivables within the scope of the standard due to the prescribed measurement principles, the Company does not expect the impact of the adoption on the consolidated financials statements to be material. In November 2021, the FASB issued ASU No. 2021-10, Government Assistance (Topic 832): Disclosure by Business Entities about Government Assistance (ASU 2021-10), which improves the transparency of government assistance received by most business entities by requiring the disclosure of: (1) the types of government assistance received; (2) the accounting for such assistance; and (3) the effect of the assistance on a business entity's financial statements. The standard became effective for annual periods beginning after December 15, 2021 and the Company has satisfied the disclosure related requirements in the footnotes of these consolidated financial statements for the year ended December 31, 2022. Recently Issued Accounting Pronouncements The Company is an “emerging growth company” as defined by the JOBS Act. The JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. In other words, an emerging growth company can selectively delay |
