Summary of Significant Accounting Policies	Note 3. Summary of Significant Accounting Policies Cash Cash consists of all cash on hand and deposits. Our cash was held primarily in checking accounts and an Institutional Insured Liquid Deposit demand account as of December 31, 2024 and 2023. At times the amount of cash on deposit may exceed the federally insured limit of the bank. Deposit accounts at each of the institutions are insured up to $250,000 by the Federal Deposit Insurance Corporation (FDIC). At December 31, 2024 and 2023, the Company exceeded FDIC limits at various institutions. The Company has not experienced any losses in such accounts. Equity Investments Equity investments (including equity securities) with readily determinable fair value are reported at fair value, with unrealized gains and losses included in the determination of net income (loss). For equity investments with no readily determinable fair value, we measure these investments at cost less impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. Such observable price changes may include instances where the investee issues equity securities to new investors, thus creating a new indicator of fair value, as an example. As of each of December 31, 2024 and 2023, the total carrying value of our equity investments, with no readily determinable fair value, was $0.3 million, and are included in other non-current assets on our Consolidated Balance Sheets. On an annual basis, we perform a qualitative assessment considering impairment indicators to evaluate whether these investments are impaired and also monitor for any observable price changes. During the years ended December 31, 2024 and 2023, we did not have any impairment loss on these investments. Accounts Receivable The majority of our accounts receivable and revenue are from commercial insurance payers and government payers, such as Medicare, the Veterans Administration and Medicaid. Accounts receivable are recorded based on management’s assessment of the expected consideration to be received, based on a detailed review of historical pricing adjustments and collections. Management relies on the results of the assessment, which includes payment history of the applicable payer as well as historical patient collections, as a primary source of information in estimating the collectability of our accounts receivable. We update our assessment on a quarterly basis, which to date has not resulted in any material adjustments to the valuation of our accounts receivable. We believe the assessment provides reasonable estimates of our accounts receivable valuation, and therefore we believe that substantially all accounts receivable are fully collectible. A portion of claims to Medicare are initially denied and enter the appeals process, where many are ultimately reviewed by an Administrative Law Judge. After final adjudication of all claims, approximately 90% of the claims submitted are approved (this is on a number of claims, not a dollars claimed, basis across all our products). The appeals process can be lengthy, lasting more than a year in most cases. Accordingly, we classify a portion of our Medicare accounts receivable as non-current based on our experience with Medicare collections. Inventories Inventories are valued at the lower of cost (first-in, first-out method) or net realizable value. Property and Equipment Property and equipment are stated at cost and are depreciated using the straight-line method over their estimated useful lives of three to seven years. Leasehold improvements are depreciated over the remaining life of the respective building lease agreement. The value of demonstration equipment in the possession of our field sales representatives is capitalized and depreciated over the estimated useful life of the equipment. Major expenditures for property and equipment are capitalized. Maintenance, repairs and minor renewals are expensed as incurred. When assets are retired or otherwise disposed of, their costs and related accumulated depreciation are removed from the accumulated depreciation accounts and the resulting gains or losses are included in income. Software Costs We capitalize certain implementation costs incurred during the development stage of implementing new software. Capitalized costs are included within prepaid expenses and other current assets and other non-current assets on the Consolidated Balance Sheets. We expense costs as incurred during the post-implementation/operation stage. Capitalized implementation costs are amortized on a straight-line basis over the contractual term of the cloud computing arrangement, which includes renewal options that are reasonably certain to be exercised. Revenue Recognition We derive revenue from the sales and rentals of our Flexitouch Plus, Entre Plus and Nimbl systems, and from the sales of our AffloVest product. Flexitouch Plus, Entre Plus and Nimbl We recognize revenue when control of the product has been transferred to our customer, in the amount of the expected consideration to be received for the product. In general, revenue from the sale or rental of a product is recognized upon shipment, unless circumstances dictate that control has not yet passed to the customer. We provide a warranty for these products against defects in material and workmanship for a period of one to five years on garments and one to two years on controllers. In accordance with applicable accounting guidance, we have determined these were assurance warranties and therefore not considered a performance obligation. In addition, we did not evaluate immaterial promised goods or services in the context of the contract. As a result, the sale or rental of these products represent a single performance obligation that is satisfied at a point in time and is short-term in nature. In certain cases, we receive payment from Medicare sales over a period of time that may exceed one year. Despite these extended payment terms, no significant financing component is deemed to exist as the terms are not for the benefit of the patient with whom we have the contract. Rather, the extended payment terms occur as a result of an initial claim denial, which subsequently enters the Medicare appeals process as noted below. We commercially distribute these products directly to patients who are referred to us by physicians, therapists or nurses. In most cases, there is a third-party payer, such as a commercial insurer, Medicare or the Veterans Administration, involved with the transaction. Our contractual relationship resides with the patient when the third-party payer is either a commercial insurer or Medicare and with the Veterans Administration if the patient is covered under their services. Revenue is recognized from such sales upon transfer of control of the product to the customer at a transaction price determined by collection history. As a result, the transaction price is impacted by multiple factors, including the terms and conditions contracted by various third-party payers, and therefore payments from third-party payers typically are less than our standard charge and represent an implicit price concession, resulting in variable consideration. As most contracts are with each individual sale to a patient, we have elected the portfolio approach to determine the transaction price, and ultimately the expected consideration. The portfolios used to determine transaction price are at the payer level, with pricing for each payer assessed based on the underlying similar characteristics. For any of our products sold to patients covered by private payers, such as commercial insurance companies, revenue is recognized upon shipment. A product is not shipped until we have received a prescription from a physician for our products and, as applicable, receipt of prior authorization from payers. At shipment, we invoice the payer for the total product price, and we recognize revenue in the amount of cash consideration anticipated to be received based on the transaction price. After the insurance payer has remitted payment, we separately invoice the patient for their portion of the payment obligation, such as copayments and deductibles. The transaction price is determined based on the payment history of the applicable payer drawn from actual write-off and collections experience from the payer over a rolling 12-month period, as well as historical patient collections. For our products sold to Medicare patients, we recognize revenue from such sales upon shipment of our products, which can occur only after we have received a prescription from a physician and all applicable patient documentation is obtained. The transaction price for our Entre Plus and Nimbl systems is determined based on the payment history using the same methodology as our private insurers. A portion of claims for payment for our Flexitouch Plus system are initially denied, and enter the appeals process, which can be lengthy. We assess the variable consideration for each of these claims as a percentage of the total invoice price based on ultimate approval and collection history. For our products sold to the Veterans Administration on behalf of the patient, our contract is with the Veterans Administration rather than the patient. We enter into individual sales contracts with the Veterans Administration on behalf of each patient. These contracts determine the amount of consideration, which is typically paid in full within 2-3 days of shipment, and therefore there is no implicit price concession. In addition, the contracts provide for the right of control to transfer to the Veterans Administration upon delivery of the product to the patient, at which time revenue is recognized. We incur incremental costs that directly relate to the sales of our products; however, as the amortization period would be less than one year, we have elected the practical expedient to expense these costs as incurred. We sell and rent these products either directly to patients or the Veterans Administration on behalf of patients, who are referred to us by physicians, therapists or nurses. We bill private insurers and other payers, Medicare, and the Veterans Administration directly for purchases or rentals of our product on behalf of a patient and bill patients directly for their cost-sharing amounts, including any portion of an unsatisfied deductible and any copayments or co-insurance obligation. A portion of our revenue is derived from patients who obtain our products under multiple-month rental arrangements. We bill these patients’ insurance payers monthly over the duration of the rental term. Title to these products passes to the patients at the end of the rental period. Rental agreements are recorded as sales-type leases in accordance with Accounting Standards Update (“ASU”) No. 2016-02, “Leases” (Topic 842) (“ASC 842”). Accordingly, as sales-type leases, the transaction price for the entire rental term is recognized upon transfer of control. AffloVest The AffloVest device is sold through durable medical equipment providers. Revenue is recognized when control of the promised goods or services is transferred to the distributors, in an amount that reflects the consideration we expect to be entitled to in exchange for transferring those goods or providing services. We account for a contract when it has approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. When determining whether the distributor has obtained control of the goods or services, we consider any future performance obligations. Generally, there is no post-shipment obligation on products sold other than warranty obligations in the normal and ordinary course of business. Consequently, revenue from the sale of the AffloVest product is recognized at shipment, unless circumstances dictate that control has not yet passed to the distributor. Certain of our contracts include volume-based incentives which involve rebates that are negotiated at or prior to the time of sale with the customer and are redeemable only if the customer achieves a specified cumulative level of sales or sales increase. Under these incentive programs, at the time of sale, we determine the most likely amount of the rebate to be paid based on forecasted sales levels. These forecasts are updated at least quarterly for applicable customers, and the transaction price is reduced for the anticipated cost of the rebate. If the forecasted sales for a customer change, the accrual for rebates is adjusted to reflect the new rebates expected to be earned by the customer. Amounts billed to customers for shipping and handling activities after the customer obtains control are treated as a promised service performance obligation and recorded in revenue in the accompanying Consolidated Statements of Operations. Shipping and handling costs incurred for the delivery of goods to customers are considered a cost to fulfill the contract and are included in cost of revenue sold in the accompanying Consolidated Statements of Operations. We provide a warranty for the AffloVest products against defects in material and workmanship for a period of five years. In accordance with applicable accounting guidance, we have determined these were assurance warranties and therefore not considered a performance obligation. In addition, we did not evaluate immaterial promised goods or services in the context of the contract. As a result, the sale of these products represents a single performance obligation that is satisfied at a point in time and is short-term in nature. Research and Development Costs We expense research and development costs as incurred, including expenses associated with clinical research studies and development. Shipping and Handling Costs Amounts billed to customers for shipping and handling activities after the customer obtains control are treated as a promised service performance obligation and recorded in total revenue in the accompanying Consolidated Statements of Operations. Shipping and handling costs incurred for the delivery of goods to customers are considered a cost to fulfill the contract and are included in cost of revenue in the accompanying Consolidated Statements of Operations. Product Warranty We provide a warranty for our products against defects in material and workmanship for a period of one to five years. We record a liability for future warranty claims at the time of sale for the warranty period offered to a customer. If the assumptions used in calculating the provision were to materially change, such as incurring higher than anticipated warranty claims, an additional provision may be required. Impairment of Long-Lived Assets We review long-lived assets, including property and equipment and patents, for impairment whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be fully recoverable. We will assess long-lived assets used in operations for impairment indicators, including when undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amount (see Note 8 – “Goodwill and Intangible Assets”). Goodwill Goodwill represents the excess of the purchase price paid over the estimated fair value of the net assets acquired and liabilities assumed in the acquisition of a business. Goodwill is not amortized, but is tested for impairment at least annually or on an interim basis if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. We perform our annual assessment of goodwill for impairment as of July 1st of each fiscal year. See Note 8 – “Goodwill and Intangible Assets” for additional information. Stock-Based Compensation We provide stock-based compensation in the form of various types of equity-based awards, including time-based restricted stock units, performance-based restricted stock units, stock options, and through our Employee Stock Purchase Plan (“ESPP”). Stock-based compensation expense is based on the estimated fair value of the award on the grant date for equity awards, or on the first date of the ESPP purchase period for shares under the ESPP, and recognized over the requisite service periods on our Consolidated Statements of Income using the straight-line expense attribution approach. The estimated fair value of time-based and performance based restricted stock units is based on the closing price of our common stock on the grant date. Stock options and ESPP shares are valued using the Black-Scholes option-pricing model. The Black-Scholes valuation model requires the input of highly subjective assumptions. The assumptions include the expected term of the option or ESPP shares, the expected volatility of the price of our common stock, expected dividend yield and the risk-free interest rate. These estimates involve inherent uncertainties and the significant application of management’s judgment. If factors change and different assumptions are used, our stock-based compensation expense could be materially different in the future (see Note 13 – “Stockholders’ Equity”). Income Taxes Income taxes are accounted for under the liability method. Deferred income taxes are provided for temporary differences between the financial reporting and the tax basis of assets and liabilities. If we determine in the future that it is more likely than not that we will not realize all or a portion of the deferred tax assets, we will record a valuation allowance in the period the determination is made (see Note 15 – “Income Taxes”). Changes in tax rates are reflected in the tax provision as they occur. Net Income (Loss) Per Common Share Basic net income (loss) per common share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per common share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential stock-based awards outstanding during the period using the treasury stock method. Dilutive potential stock-based awards include outstanding common stock options, time- and performance-based restricted stock units and ESPP shares. Business Segments The Company operates as one operating segment. The Company's Chief Operating Decision Maker ("CODM") is its Chief Executive Officer, who reviews financial information presented on a consolidated basis. The CODM uses consolidated net income (loss) as the measure of segment profit or loss. Significant segment expenses are those expenses reported in the Consolidated Statement of Operations. The CODM assesses performance for the segment, allocates resources and monitors budget versus actual results using consolidated revenue and net income (loss) which is reflected in the Consolidated Statement of Operations. Accounting Pronouncement Not Yet Adopted In November 2024, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses” which requires entities to disclose additional information about specific expense categories in the notes to financial statements on an annual and interim basis. The guidance is effective for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the effect that this standard will have on its consolidated financial statements and related disclosures. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” which requires entities to enhance disclosures around income taxes. The guidance is effective for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is currently evaluating the effect this standard will have on its consolidated financial statements and related disclosures. Recently Adopted Accounting Pronouncement In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” which requires entities to enhance disclosures around segment reporting. The guidance is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 with respect to the year ended December 31, 2024. As a result, we have enhanced our segment disclosures in this report. The adoption of this ASU affects only our disclosures, with no impacts to our financial condition and results of operations.

Impairment of Long-Lived Assets

We review long-lived assets, including property and equipment and patents, for impairment whenever events or changes in business circumstances indicate that the carrying amount of an asset may not be fully recoverable.

Net Income (Loss) Per Common Share

Basic net income (loss) per common share is computed based on the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per common share is computed based on the weighted average number of shares of common stock plus the effect of dilutive potential stock-based awards outstanding during the period using the treasury stock method. Dilutive potential stock-based awards include outstanding common stock options, time- and performance-based restricted stock units and ESPP shares.

In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” which requires entities to enhance disclosures around segment reporting. The guidance is effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 with respect to the year ended December 31, 2024. As a result, we have enhanced our segment disclosures in this report. The adoption of this ASU affects only our disclosures, with no impacts to our financial condition and results of operations.
