| Summary of Significant Accounting Policies | NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Because future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Any changes in these estimates will be reflected in the Company’s Consolidated Financial Statements. Significant items subject to such estimates and assumptions include the determination of the collectability of trade receivables, inventory obsolescence, impairment of long-lived assets, recoverability of goodwill and intangible assets, contingent earn-out liability, income taxes and stock-based compensation. Foreign Currency Translation The Consolidated Financial Statements are presented in U.S. dollars. The Company’s non-U.S. subsidiaries have a functional currency (i.e., the currency in which operational activities are primarily conducted) that is other than the U.S. dollar, generally the currency of the country in which such subsidiaries are domiciled. Such subsidiaries’ assets and liabilities are translated into U.S. dollars at year-end exchange rates, while revenue and expenses are translated at average exchange rates during the year based on the daily closing exchange rates. Adjustments that result from translating amounts from a subsidiary’s functional currency to U.S. dollars are reported in Accumulated Other Comprehensive (Loss) Income, net of tax. Business Combinations We allocate the purchase consideration to the identifiable net assets acquired, including intangible assets and liabilities assumed, based on estimated fair values at the date of the acquisition. The excess of the fair value of the purchase consideration over the fair value of the identifiable assets and liabilities, if any, is recorded as goodwill. During the measurement period, which is up to one year from the acquisition date, we may adjust provisional amounts that were recognized at the acquisition date to reflect new information obtained about facts and circumstances that existed as of the acquisition date. Determining the fair value of assets acquired and liabilities assumed requires significant judgment, including the selection of valuation methodologies including the income approach, the cost approach, and the market approach. Significant assumptions used in those methodologies include, but are not limited to, the expected values of the underlying metric, the systematic risk embedded in the underlying metric, the volatility of the underlying metric, the risk-free rate, and the counterparty risk. The use of different valuation methodologies and assumptions is highly subjective and inherently uncertain and, as a result, actual results may differ materially from estimates. Cash Cash consists of highly liquid investments with an original maturity of three months or less. There are no contractual or other restrictions as to the use of cash. Trade Receivables, Less Allowance for Doubtful Accounts Trade receivables due from customers are uncollateralized customer obligations due under normal trade terms requiring payment within 30 days from the invoice date and are stated at the amount billed to the customer. Trade receivables also include unbilled receivables due from customers that represent completed surgical cases that are pending customer-issued purchase orders. These unbilled receivables are covered by agreements with customers, the products have typically been used in a surgery, and collection is determined to be probable. The Company estimates an allowance for doubtful accounts based upon an evaluation of the current status of receivables, historical experience, and other factors as necessary. It is reasonably possible that the Company’s estimate of the allowance for doubtful accounts will change. Activity in the allowance for doubtful accounts consisted of the following:
December 31,
2022 2021
Allowance for doubtful accounts, beginning of year $ 1,032 $ 1,296
Additions charged against revenue or to expense 1,853 1,027
Deductions ( 1,197 ) ( 1,291 )
Allowance for doubtful accounts, end of year $ 1,688 $ 1,032 Inventories, Net Inventories are considered finished goods and are purchased from third party contract manufacturers. These inventories consist of implants, hardware, and consumables and are held in our warehouse, with third-party independent sales representatives or distributors, or consigned directly with hospitals. Inventories are stated at the lower of cost (weighted average cost basis) or net realizable value. When sold, inventory is relieved at weighted average cost. We evaluate the carrying value of our inventories in relation to the estimated forecast of product demand, which takes into consideration the life cycle of the product. A significant decrease in demand or development of products could result in an increase in the amount of excess inventory on hand, which could lead to additional charges for excess and obsolete inventory. The Company estimates a reserve for obsolete and slow-moving inventory based on current inventory levels, historical sales and future projected demand. Charges for excess and obsolete inventory are included in Cost of goods sold and were $ 485 , $ 2,850 and $ 7,467 for the years ended December 31, 2022, 2021 and 2020, respectively. The inventory reserve w as $ 16,804 a nd $ 19,374 as of December 31, 2022 and 2021, respectively. The need to maintain substantial levels of inventory impacts our estimates for excess and obsolete inventory. Each of our implant systems are designed to include implantable products that come in different sizes and shapes to accommodate the surgeon’s needs related to the patient’s anatomical size. Typically, a small number of the set components are used in each surgical procedure. Certain components within each set may become obsolete before other components based on the usage patterns. We adjust inventory values, as needed, to reflect these usage patterns and life cycle. Property and Equipment, Net Property and equipment is recorded at cost less accumulated depreciation. Expenditures for renewals and improvements that significantly add to the productive capacity or extend the useful life of an asset are capitalized and included in Property and equipment, net in the Consolidated Balance Sheets. Expenditures for maintenance and repairs are charged to expense as incurred and are included in Selling, general, and administrative expense in the Consolidated Statements of Operations and Comprehensive (Loss) Income. When equipment is retired or sold, the cost and related accumulated depreciation are eliminated from the accounts and the resulting gain or loss is included in included in Selling, general and administrative in the Consolidated Statements of Operations and Comprehensive (Loss) Income. Depreciation is provided using the straight-line method based on useful lives of the assets which range from three to twenty-five years , which best reflects the pattern of use. The Company depreciates surgical instrumentation, once available for use, over a five-year period and cases, once available for use, over a three-year period. Depreciation for surgical instrumentation used in surgery is included in Selling, general, and administrative expense in the Consolidated Statements of Operations and Comprehensive (Loss) Income. Leasehold improvements are amortized using the straight-line method over the shorter of the asset’s useful life or the lease term. Property and equipment are assessed for impairment upon triggering events that indicate that the carrying value of an asset group may not be recoverable. Recoverability is measured by a comparison of the carrying amount to future net undiscounted cash flows of the asset group expected to be generated from its use and eventual disposition. If the asset group’s carrying value is determined to not be recoverable, the impairment to be recognized is measured by which the carrying amount exceeds the fair value of the asset group. No impairment charges related to property and equipment were recorded in any of the periods presented. Intangibles The costs associated with applying for patents and trademarks are capitalized. Patents are amortized on a straight-line basis over the lesser of the patent’s economic or legal life, which is seventeen years . Costs associated with capitalized patents include third-party attorney fees and other third-party fees as well as costs related to the following: the preparation of patent applications, government filings and registration fees, drawings, computer searches, and translations related to specific patents. Trademarks that are anticipated to be renewed every ten years have an indefinite life and are not amortized but tested for impairment annually. Once it is determined a trademark will no longer be renewed, the trademark is amortized over the remainder of the trademark’s registration period. Customer relationships are amortized over an estimated useful life of three to seven years on a straight-line basis. Other intangibles, which mainly consist of noncompete arrangements, are amortized over an estimated useful life of three years on a straight-line basis. Developed technology is amortized over an estimated useful life of twelve years on a straight-line basis. Amortizable intangible assets are assessed for impairment upon triggering events that indicate that the carrying value of an asset may not be recoverable. Recoverability is measured by a comparison of the carrying amount to future net undiscounted cash flows expected to be generated by the associated asset. If the asset’s carrying value is determined to not be recoverable, the impairment to be recognized is measured by the amount by which the carrying amount exceeds the fair market value of the intangible assets. No impairment charges related to amortizable assets were recorded for the years ended December 31, 2022, 2021 and 2020. Indefinite-lived trademark assets are reviewed for impairment annually or whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The Company can elect to first apply the optional qualitative impairment assessment to determine whether the indefinite-lived intangible asset is more-likely-than-not impaired. If, on the basis of the qualitative impairment assessment, an entity asserts that it is more likely than not that the indefinite-lived intangible asset is impaired, the Company would be required to calculate the fair value of the asset for an impairment test. Impairment loss is recognized if the carrying amount of the asset exceeds its fair value. A qualitative assessment considers macroeconomic and other industry-specific factors, such as trends in short-term and long-term interest rates and the ability to access capital, and company specific factors such as trends in revenue generating activities, and merger or acquisition activity. If the Company elects to bypass qualitatively assessing its indefinite-lived intangible assets, or it is not more likely than not that the fair value of the intangible asset exceeds its carrying value, management estimates the fair value of the intangible asset and compares it to the carrying value. The estimated fair value of the intangible asset is established using an income approach based on a discounted cash flow model that includes significant assumptions about the future operating results and cash flows of the intangible asset or assets. The Company elected to perform a qualitative analysis for its indefinite-lived intangible assets as of October 1, 2022, the annual test date. The Company determined, after performing the qualitative analysis that there was no evidence that it is more likely than not that the fair value of its intangible assets was less than the carrying amount. Therefore, it was not necessary to perform a quantitative impairment test. Goodwill Goodwill represents the excess of the purchase price as compared to the fair value of net assets acquired and liabilities assumed. Goodwill is not amortized, but is tested for impairment annually or when indications of impairment exist. We can elect to qualitatively assess goodwill for impairment if it is more likely than not that the fair value of a reporting unit exceeds its carrying value. Impairment exists when the carrying amount, including goodwill, of the reporting unit exceeds its fair value, resulting in an impairment charge for this excess (not t o exceed the carrying amount of the goodwill). The impairment, if determined, is recorded within Operating expenses in the Consolidated Statements of Operations and Comprehensive (Loss) Income in the period the determination is made. Contingent Earn-out Consideration Business combinations may include contingent earn-out consideration as part of the purchase price under which the Company will make future payments to the seller upon the achievement of certain milestones. The fair value of the contingent earn-out consideration is estimated as of the acquisition date at the present value of the expected contingent payments and is subsequently remeasured at each balance sheet date. Two methodologies may be considered in the valuation: the scenario-based model (“SBM”) and Monte Carlo simulation. The SBM relies on multiple outcomes to estimate the likelihood of future payoff of the contingent consideration. The resulting earnout payoff is then probability-weighted and discounted at an appropriate risk adjusted rate in order to arrive at the present value of the expected earnout payment. The Monte Carlo simulation is used to value the non-linear contingent considerations based on projected financial metrics. Each trial of the Monte Carlo simulation draws a value from the assumed distribution for the underlying metric. The earnout payoff for each simulation trial is calculated based on that particular simulated path for the underlying metrics and then discounted to present value using the risk-free rate, adjusted for counterparty credit risk. The value of the earnout is estimated as the average value from all simulation trials. The fair value estimates use unobservable inputs that reflect our own assumptions as to the ability of the acquired business to meet the targeted benchmarks and discount rates used in the calculations. The unobservable inputs are defined in ASC Topic 820, “Fair Value Measurements and Disclosures,” as Level 3 inputs. We review the probabilities of achievement of the earnout milestones to determine impact on the fair value of the earnout consideration on a quarterly basis over the earn-out period. Actual results are compared to the estimates and probabilities of achievement used in our forecasts. Should actual results of the acquired business increase or decrease as compared to our estimates and assumptions, the estimated fair value of the contingent earn-out consideration liability will increase or decrease, up to the contractual limit, as applicable. Changes in the estimated fair value of the contingent earn-out consideration are recorded in other (expense) income in the Consolidated Statements of Operations and Comprehensive (Loss) Income and are reflected in the period in which they are identified. Changes in the estimated fair value of the contingent earn-out consideration may materially impact or cause volatility in our operating results. Income Taxes The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement 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 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 regularly reviews its deferred tax assets for recoverability and establishes a valuation allowance if it is more likely than not that some portion, or all, of a deferred tax asset will not be realized. The determination as to whether a deferred tax asset will be realized is made on a jurisdictional basis and is based on both positive and negative evidence. This evidence includes historic taxable income, projected future taxable income, the expected timing of the reversal of existing temporary differences and the implementation of tax planning strategies. The calculation of tax liabilities involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions. Accounting Standards Codification (ASC) No. 740 states that a tax benefit from an uncertain tax position may be recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolution of any related appeals or litigation processes, on the basis of its technical merits. The Company records unrecognized tax benefits as liabilities in accordance with ASC 740 and adjusts these liabilities when management’s judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from the current estimate of the unrecognized tax benefit liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available. The Company records uncertain tax positions in accordance with Accounting Standards Codification (“ASC”) Topic 740 on the basis of a two-step process in which (1) the Company determines whether it is more-likely-than-not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, the Company recognizes the largest amount of tax benefit that is more than 50 percent likely to be realized upon ultimate settlement with the related tax authority. The Company evaluates its tax positions that have been taken or are expected to be taken on income tax returns to determine if an accrual is necessary for uncertain tax positions. The Company will recognize interest and penalties as a component of income tax expense if incurred. Revenue Recognition We account for revenue in accordance with ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). Revenue is generated primarily from the sale of our implants and disposables and, to a much lesser extent, from the sale of our surgical instrumentation. We sell our products through employee sales personnel, and independent sales representatives in the U.S. Outside the U.S. sales are through independent sales representatives and to stocking distributors. We have consignment agreements with certain distributors and hospitals. Our customers are primarily hospitals and surgery centers. Revenue is recorded, net of estimated losses for bad debts, when our performance obligation is satisfied which is when our customers take title of the product, and typically when the product is used in surgery. We generally have written contracts with our customers which incorporate pricing and our standard terms and conditions. Any discounts we offer are outlined in our customer agreements. As the discounts are known at the time of purchase, no estimates are required at the time of revenue recognition. Shipping and handling costs are recorded as cost of goods sold and amounts billed to customers for shipping and handling costs are recorded in revenue. We record as revenue any amounts billed to customers for shipping and handling costs and record as cost of goods sold the actual shipping costs incurred. We have elected to exclude from the measurement of the transaction price all taxes (e.g., sales, use, value-added) assessed by government authorities and collected from a customer. Therefore, revenue is recognized net of such taxes. We have elected to use the practical expedient allowed under ASC 606 to account for shipping and handling activities that occur after the customer has obtained control of a promised good as fulfillment costs rather than as an additional promised service and, therefore, we do not allocate a portion of the transaction price to a shipping service obligation. Commissions to sales agents for the sales exceeding their quotas are classified as incremental costs of obtaining a contract as such costs would not have been incurred if the contract was not signed. We have elected to use the practical expedient to expense such costs that should be capitalized as the amortization period of the costs would be less than one year . Due to the nature of our products, returns are minimal and an estimate for returns is not material. The timing of revenue recognition may differ from the timing of invoicing to our customers . We have recorded unbilled accounts receivable involving management judgement related to this timing difference of $ 4,511 and $ 3,637 as of December 31, 2022 and December 31, 2021 , respectively. Cost of Goods Sold Cost of goods sold consists primarily of products purchased from third-party suppliers, freight, shipping, excess and obsolete inventory charges and royalties. Implants are manufactured to our specifications by third-party suppliers. Most implants are produced in the U.S. Cost of goods sold is recognized for consigned implants at the time the implant is used in surgery and the related revenue is recognized. Prior to their use in surgery, the cost of consigned implants is recorded as Inventories, net in our Consolidated Balance Sheets. Stock-Based Compensation All stock-based awards to employees and nonemployee contractors, including any grants of stock, stock options, restricted stock units (“RSU”), performance stock units ("PSU") and the option to purchase common stock under the Employee Stock Purchase Plan (“ESPP”), are measured at fair value at the grant date and recognized over the relevant vesting period in accordance with the ASC Topic 718 (“ASC 718”). Stock-based awards to nonemployees are recognized as a selling, general and administrative expense over the period of performance. Such awards are measured at fair value at the date of grant. In addition, for awards that vest immediately, the awards are measured at fair value and recognized in full at the grant date. The Company estimates the fair value of each stock-based award containing service and/or performance conditions on the grant date using the Black-Scholes option valuation model which incorporates assumptions as to stock price volatility, the expected life of the options, risk-free interest rate and dividend yield. The Company relies on its historical volatility as an input to the option pricing model as management believes that this rate will be representative of future volatility over the expected term of the options. The expected term until exercise represents the weighted-average period of time that options granted are expected to be outstanding giving consideration to vesting schedules and the Company’s historical exercise patterns. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. The Company has not paid any dividends since its inception and does not anticipate paying any dividends for the foreseeable future, so the dividend yield is assumed to be zero. Forfeitures are recorded as they occur, and when they occur compensation expense previously recognized is reversed in the period of the forfeiture. Option awards are generally granted with an exercise price equal to the fair value of the Company’s common stock at the date of grant. Subsequent to the IPO, the fair value of the Company’s common stock underlying its equity awards is based on the quoted market price of the Company’s common stock on the grant date. Prior to the IPO, because there was no public market for the Company’s common stock, the fair value of the common stock underlying the stock awards has historically been determined at the time of grant of the stock option by considering a number of objective and subjective factors, including sales of shares of common stock, third-party valuations performed, important developments in the Company’s operations, actual operating results and financial performance, the conditions in the medical device industry and the economy in general, and the stock price performance, volatility of comparable public companies, and an assumption for a discount for lack of marketability, among other factors. Research and Development Research and development expense is comprised of in-house research and development of new products and technologies, clinical studies and trials, regulatory expenses, and employee related compensation and expenses. We maintain a procedurally focused approach to product development and have projects underway to add new products to our existing systems and to add new systems across multiple foot and ankle indications. Leases At the inception of a contractual arrangement, the Company determines whether the contract contains a lease by assessing whether there is an identified asset and whether the contract conveys the right to control the use of the identified asset in exchange for consideration over a period of time. If both criteria are met, the Company calculates the associated lease liability and corresponding right-of-use asset upon lease commencement using a discount rate based on a borrowing rate commensurate with the term of the lease. The Company records lease liabilities within current liabilities or long-term liabilities based upon the length of time associated with the lease payments. The Company records its operating lease right-of-use assets within other assets. Contingencies A liability is contingent if the amount is not presently known but may become known in the future as a result of the occurrence of some uncertain future event. We accrue a liability for an estimated loss if we determine that the potential loss is probable of occurring and the amount can be reasonably estimated. Significant judgment is required in both the determination of probability and the determination as to whether the amount of an exposure is reasonably estimable, and accruals are based only on the information available to our management at the time the judgment is made. We expense legal costs, including those legal costs incurred in connection with a loss contingency, as incurred. Fair Value of Financial Instruments Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. There is a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2- Includes other inputs that are directly or indirectly observable in the marketplace, such as quoted market prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 - Unobservable inputs which are supported by little or no market activity. Financial instruments (principally cash, trade receivables, accounts payable and accrued expenses) are carried at cost, which approximates fair value due to the short-term maturity of these instruments. Our debt is carried at cost, which approximates fair value due to the variable interest rate associated with our debt. The Company does not have any assets or liabilities presented in the Level 1 or Level 2 categories as of December 31, 2022 and 2021, and there were no changes in level hierarchies during the years ended December 31, 2022, 2021 and 2020 . Accounting Pronouncements Issued In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASC 842”), which sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. ASU 2016-02 supersedes the previous leases standard, ASC 840, Leases. ASU 2016-02, as subsequently amended for various technical issues, is effective for emerging growth companies following private company adoption dates in fiscal years beginning after December 15, 2021, and interim periods with fiscal years beginning after December 15, 2022 and allows entities to elect an optional transition method where entities may continue to apply the existing lease guidance during the comparative periods and apply the new lease requirements through a cumulative effect adjustment in the period of adoption rather than in the earliest period presented. The Company adopted the standard on January 1, 2022 . A s part of the adoption: • We adopted the option to apply the transition requirements in ASC 842 at the effective date of January 1, 2022 with the effects of initially applying ASC 842 recognized as a cumulative-effect adjustment to retained earnings in the period of adoption. • We elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed the Company to carry forward its ASC 840 assessment around definition of a lease, lease classification, and initial direct costs. • We have not elected the hindsight practical expedient to determine the lease term and right-of-use asset impairment. • We elected the short-term lease exception which allows us to account for leases with a term of 12 months or less to be accounted for similar to existing operating leases. The cost of these leases are not recognized in the right-of-use asset and lease liability balances. Consistent with ASC 842 requirements, leases that are 12 month or less are not included in the disclosures. • We elected to not separate non-lease components. This expedient allows us to not separate lease and non-lease components and to account for both components as a single lease component, recognized on the balance sheet. This resulted in increases of lease liabilities and leased assets. This election has been applied to all classes of underlying assets. The adoption of this standard did not have a material impact on our financial position and results of operations. See Note 14 - Commitments and Contingencies for mo re detail regarding our disclosures. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which requires entities to estimate all expected credit losses for certain types of financial instruments, including trade receivables, held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. The updated guidance also expands the disclosure requirements to enable users of financial statements to understand the entity’s assumptions, models and methods for estimating expected credit losses over the entire contractual term of the instrument from the date of initial recognition of that instrument. ASU 2016-13, as subsequently amended for various technical issues, is effective for emerging growth companies following private co |
