SIGNIFICANT ACCOUNTING POLICIES | SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements include the accounts of OrthoPediatrics Corp. and its wholly-owned subsidiaries, OrthoPediatrics US Distribution Corp., OrthoPediatrics EU Limited, OrthoPediatrics AUS PTY LTD, OrthoPediatrics NZ Limited, OP EU B.V., OP Netherlands B.V., Orthex, LLC, Telos Partners, LLC and ApiFix, Ltd. (collectively, the “Company,” “we,” “our” or “us”). All intercompany balances and transactions have been eliminated. The results of Vilex have been classified as discontinued operations within the consolidated financial statements for the year ended December 31, 2019. We have prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The accompanying consolidated financial statements have been prepared assuming our Company will continue as a going concern. We have experienced recurring losses from operations since our inception and had an accumulated deficit of $161,766 and $128,822 as of December 31, 2020 and 2019, respectively. On July 15, 2020, the Company repaid the $20,000 principal amount outstanding under the Loan Agreement’s Term Note A, together with all unpaid interest and other related amounts payable. On August 4, 2020, the Company entered into a Second Amendment to its First Amended Loan Agreement with Squadron. The Loan Agreement’s revolving credit commitment was increased from the previously established $15,000 to $25,000. The Company did not have an outstanding balance as of December 31, 2020. Management continues to monitor cash flows and liquidity on a regular basis. We believe that our cash balance at December 31, 2020 and expected cash flows from operations for the next twelve months subsequent to the issuance of the consolidated financial statements, are sufficient to enable us to maintain current and essential planned operations for more than the next twelve months. On December 11, 2018, we completed a follow-on offering of our common stock, in which we issued and sold 1.725 million shares of common stock at a public offering price of $27.00 per share for aggregate gross proceeds of $46,575. We received $43,423 in net proceeds after deducting $2,800 of underwriting discounts and commissions and paying $352 in offering costs. On December 13, 2019, we completed a follow-on offering of our common stock, in which we issued and sold 1.755 million shares at a public offering price of $36.50 per share for aggregate gross proceeds of $64,076. We received $59,996 in net proceeds after deducting $3,845 of underwriting discounts and commissions and paying $235 in underwriting commissions and offering costs. On June 22, 2020, we completed a follow-on offering of our common stock, in which we issued and sold 1.6 million shares of common stock at a public offering price of $47.00 per share for aggregate gross proceeds of $75,200. We received $70,207 in net proceeds after deducting $4,512 of underwriting discounts and commissions and paying $481 in offering costs. Use of Estimates Preparation of our consolidated financial statements requires the use of estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses, as of the date of the consolidated financial statements. By their nature, these judgments are subject to an inherent degree of uncertainty. We use historical experience and other assumptions as the basis for our judgments and estimates. 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 our consolidated financial statements. Foreign Currency Transactions We currently bill our international stocking distributors in U.S. dollars, resulting in minimal foreign exchange transaction expense. Beginning in the second quarter of 2017, we began selling direct within the United Kingdom, Ireland, Australia and New Zealand and billing using the local currency for each country.We began selling direct to Canada in September 2018, Belgium and the Netherlands in January 2019, Italy in March 2020 and Germany, Switzerland and Austria in January 2021. In the year ended December 31, 2020, the Company recorded a $2,730 revenue reduction due to the repurchase of inventory from a stocking distributor in Germany, Austria and Switzerland that we converted to a sales agency. Additionally, in March 2019, we established an operating company in the Netherlands in order to enhance our operations in Europe. The financial statements of our foreign subsidiaries are accounted for in local functional currencies and have been translated into U.S. dollars using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. Foreign currency translation adjustments have been recorded as a separate component of the consolidated statements of comprehensive loss. Fair Value of Financial Instruments The accounting standards related to fair value measurements define fair value and provide a consistent framework for measuring fair value under the authoritative literature. Valuation techniques are based on observable and unobservable inputs. Observable inputs reflect readily obtainable data from independent sources, while unobservable inputs reflect market assumptions. This guidance only applies when other standards require or permit the fair value measurement of assets and liabilities. The guidance does not expand the use of fair value measurements. A fair value hierarchy was established, which prioritizes the inputs used in measuring fair value into three broad levels. Level 1 – Quoted prices in active markets for identical assets or liabilities; Level 2 – Observable market-based inputs or unobservable inputs that are corroborated by market data; and Level 3 – Significant unobservable inputs that are not corroborated by market data. Generally, these fair value measures are model-based valuation techniques such as discounted cash flows, and are based on the best information available, including our own data. The Company's financial instruments include cash and cash equivalents, short-term investments, accounts receivable, accounts payable, acquisition installment payables, contingent consideration and long-term debt. The carrying amounts of accounts receivable, accounts payable, acquisition installment payables and long-term debt approximate the fair value due to the short-term nature or market rates of these instruments. The company bases the fair value of short-term investments on quoted market prices for identical or comparable assets. Contingent consideration represents the system sales payment the Company is obligated to make. The fair value of the contingent consideration payment is considered a level 3 fair value measurement and was determined with the assistance of an independent valuation specialist at the original issuance date and as of the balance sheet date. See Note 6 for further discussion of financial instruments that carried a fair value on a recurring and nonrecurring basis. Revenue from Contracts with Customers The Company adopted ASC 606, " Revenue From Contracts with Customers (ASC 606)", on January 1, 2018 using the modified retrospective method for all contracts not completed as of the date of adoption. The adoption of ASC 606 did not have any impact on the Company's consolidated historical financial statements. The reported results for 2019 and 2018 reflect the application of ASC 606 guidance. In accordance with ASC 606, revenue is recognized when our performance obligations under the terms of a contract with our customer are satisfied. This typically occurs when we transfer control of our products to the customers, generally upon implantation or when title passes upon shipment. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these goods or services, and excludes any sales incentives or taxes collected from a customer which are subsequently remitted to government authorities. Revenue Recognition – United States Revenue in the United States is generated primarily from the sale of our implants and, to a much lesser extent, from the sale of our instruments. Sales in the United States are primarily to hospital accounts through independent sales agencies. We recognize revenue when our performance obligations under the terms of a contract with our customer are satisfied. The products are generally consigned to our independent sales agencies, and revenue is recognized when the products are used by or shipped to the hospital for surgeries on a case by case basis. On rare occasions, hospitals purchase product for their own inventory, and revenue is recognized when the products are shipped and the title and risk of loss passes to the customer. Pricing for each customer is dictated by a unique pricing agreement. Sales through two of our independent sales agencies in the United States accounted for 14.2% and 13.8% of our global revenue in 2020. Sales through two of our independent sales agencies in the United States accounted for 12.3% and 12.2% of our global revenue in 2019, respectively. Sales through two of our independent sales agencies in the United States accounted for 12.1% and 11.2% of our global revenue in 2018, respectively. Revenue Recognition – International Outside of the United States, we sell our products directly to hospitals through independent sales agencies or to independent stocking distributors. Generally, the distributors are allowed to return products, and some are thinly capitalized. Prior to 2019, we concluded that collectibility was not reasonably assured at the time of delivery for certain customers who had not evidenced a consistent pattern of timely payment. Accordingly, in the past we did not recognize international revenue and associated cost of revenue at the time title transfers for these customers for whom collectibility had not been deemed probable based on the customer’s history and ability to pay, but rather when cash had been received. Following a review of our collection history, we deemed collectibility was probable for all international stocking distributors effective January 1, 2019. Based on a history of reliable collections, we have concluded that a contract exists and revenue should be recognized when we transfer control of our products to the customer, generally when title passes upon shipment. Additionally, based on our history of immaterial returns from international customers, we have historically estimated no reserve for returns. In early 2017, we expanded operations and established legal entities in the United Kingdom, Australia and New Zealand, permitting us to sell under an agency model direct to local hospitals in these countries. We began selling direct to Canada in September 2018, Belgium and the Netherlands in January 2019, Italy in March 2020 and Germany, Switzerland and Austria in January 2021. In the year ended December 31, 2020, the Company recorded a $2,730 revenue reduction due to the repurchase of inventory from a stocking distributor in Germany, Austria and Switzerland that we converted to a sales agency. Additionally, in March 2019, we established an operating company in the Netherlands in order to enhance our operations in Europe. The products are generally consigned to our independent sales agencies, and revenue is recognized when the products are used by or shipped to the hospital for surgeries on a case by case basis. On rare occasions, hospitals purchase products for their own inventory, and revenue is recognized when title passes upon shipment. Pricing for each customer is dictated by a unique pricing agreement. Cash, Cash Equivalents and Short Term Investments We maintain cash in bank deposit accounts which, at times, may exceed federally insured limits. To date, we have not experienced any loss in such accounts. We consider all highly liquid investments with original maturity of three months or less at inception to be cash equivalents. The carrying amounts reported in the balance sheets for cash are valued at cost, which approximates fair value. The Company invests in available-for-sale short term investments. The Company has the ability, if necessary, to liquidate without penalty any of its short term investments to meet its liquidity needs in the next twelve months. As such, those investments with contractual maturities greater than one year from the date of purchase are classified as short-term on the accompanying Consolidated Balance Sheets. The company includes unrealized gains or losses in stockholders' equity. If the adjustment to fair value reflects a decline in the value of the investment, the Company considers available information to determine whether the decline is "other than temporary" and, if so, reflects the change on the Consolidated Statements of Operations. Restricted Cash In conjunction with the sale of Vilex, $1,250 was placed into a separate escrow account. This cash is reported as restricted cash on the December 31, 2020 and 2019 consolidated balance sheet. These funds will remain restricted until August 31, 2021 at which time, they will be released to the Company subject to no claims related to the purchase. The Company also maintains restricted cash of 100 Euro at its Netherlands entity for potential Italian tenders. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are uncollateralized customer obligations due under normal trade terms, generally requiring payment within 30 days from the invoice date in the United States and within 90 days internationally. Account balances with invoices over 30 or 90 days past due for domestic and international accounts, respectively, are considered delinquent. No interest is charged on past due accounts. Payments of accounts receivable are applied to the specific invoices identified on the customer's remittance advice or, if unspecified, to the customer's account as an unapplied credit. The carrying amount of accounts receivable is reduced by an allowance that reflects management's best estimate of the amounts that will not be collected, determined principally on the basis of historical experience, management's assessment of the collectability of specific customer accounts and the aging of the accounts receivable. All accounts or portions thereof deemed to be uncollectible or to require an excessive collection cost are written off to the allowance for doubtful accounts. The allowance for doubtful accounts was $433 and $506 as of year ended December 31, 2020 and 2019, respectively. The following table summarizes activity in the allowance for doubtful accounts: December 31, 2020 2019 2018 Balance at beginning of year $ 506 $ 134 $ 143 Additions charged to expense 274 424 3 Write-offs 347 52 12 Balance at end of year $ 433 $ 506 $ 134 Inventories, net Inventories are stated at the lower of cost or net realizable value, with cost determined using the first-in-first-out method. Inventories, which consist of implants and instruments held in our warehouse, with third-party independent sales agencies or distributors, or consigned directly with hospitals, are considered finished goods and are purchased from third parties. 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 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 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. 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. In addition, we continue to introduce new products, which may require us to take additional charges for excess and obsolete inventory in the future. Charges for excess and obsolete inventory are included in cost of revenue and were $1,269, $604 and $504 for the years ended December 31, 2020, 2019 and 2018, respectively. Costs Related to the Initial Public Offering At the time of the IPO, $1,840 of additional costs, primarily consisting of legal, accounting and other direct fees and costs related to the IPO incurred during 2017 and were initially deferred and capitalized and then reclassified to stockholders’ equity at the conclusion of our IPO on October 12, 2017. Additionally, $1,986 of additional non-cash expense related to the accelerated vesting of restricted stock was included in general and administrative expenses in 2018. Costs Related to the Follow-on Offerings On December 11, 2018, we completed a follow-on offering of our common stock. Offering expenses of $352, primarily consisting of legal, accounting and other direct fees and costs related to the offering, were initially deferred and capitalized and then reclassified to stockholders' equity at the conclusion of our follow-on offering on December 11, 2018. On December 13, 2019, we completed another offering of our common stock. Offering expenses of $235, primarily consisting of legal, accounting and other direct fees and costs related to the offering were recorded in stockholders' equity at the conclusion of our offering. On June 22, 2020, we completed another offering of our common stock. Offering expenses of $481, primarily consisting of legal, accounting and other direct fees and costs related to the offering were recorded in stockholders' equity at the conclusion of our offering. Property and Equipment, net Property and equipment are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful life of the assets. When assets are retired or otherwise disposed of, costs and related accumulated depreciation are removed from the accounts, and any resulting gain or loss is recognized in operations for the period. Maintenance and repairs that prolong or extend the useful life are capitalized, whereas standard maintenance, replacements, and repair costs are expensed as incurred. Instruments are hand-held devices, specifically designed for use with our implants and are used by surgeons during surgery. Instruments deployed in the field are carried at cost less accumulated depreciation and are recorded in property and equipment, net on the consolidated balance sheets. Sample inventory consists of our implants and instruments, and is maintained to market and promote our products. Sample inventory is carried at cost less accumulated depreciation. Depreciable lives are generally as follows: Building and building improvements 25 to 30 years Furniture and fixtures 5 to 7 years Computer equipment 3 to 5 years Business software 3 years Office and other equipment 5 to 7 years Instruments 5 years Sample inventory 2 years Amortizable Intangible Assets, net Amortizable intangible assets include fees necessary to secure various patents and licenses, including Band-Lok, the value of internally developed software, customer relationships, and non-competition agreements related to the acquisition of Orthex, and customer relationships and non-competition agreements related to the acquisitions of Telos and ApiFix. Amortization is calculated on a straight-line basis over the estimated useful life of the asset. Amortization for patents and licenses commences at the time of patent approval, and for licenses upon market launch, respectively. Amortization for assets acquired commences upon acquisition. Intangible assets are amortized over a 3 to 20 year period. 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 such assets are determined to be impaired, 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 were recorded in any of the periods presented. Goodwill and Other Intangible Assets Our goodwill represents the excess of the cost over the fair value of net assets acquired. The determination of the value of goodwill and intangible assets arising from acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair value of net tangible and intangible assets acquired. Goodwill is not amortized and is assessed for impairment using fair value measurement techniques on an annual basis or more frequently if facts and circumstances warrant such a review. The goodwill is considered to be impaired if we determine that the carrying value of our one reporting unit exceeds its respective fair value. No impairment changes were recorded in the current year. The Company tests goodwill for impairment by either performing a qualitative evaluation or a quantitative test. The quantitative assessment for goodwill requires us to estimate the fair value of our one reporting unit using either an income or market approach or a combination thereof. We have indefinite lived tradename assets that are reviewed for impairment by performing a quantitative analysis, which occurs annually in the fourth quarter, utilizing balances as of October 1, or whenever events or changes in circumstances 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 discounted cash flows expected to be generated by the associated asset. If such assets are determined to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount exceeds the fair market value of the assets. No impairment charges were recorded in any of the periods presented. Acquisition Payable and Contingent Consideration Upon the completion of an acquisition the Company may record an acquisition installment payable, contingent consideration or both. Both are recorded at their fair values as determined by management with the assistance of an independent valuation specialist at the original issuance date and are adjusted on a recurring basis. Accretion of interest expense attributable to the acquisition installment payable are recorded as a component of interest expense, net. Changes in the fair value of the contingent consideration are included in fair value adjustments of contingent consideration. The amount of expense recorded in interest expense, net and fair value adjustments of contingent consideration for the year ended December 31, 2020 were $2,397 and $3,520, respectively. Shipping and Handling Costs Shipping and handling costs that are billed to the customer are included in net revenue and were $635, $599 and $513, for the years ended December 31, 2020, 2019 and 2018, respectively. Shipping and handling costs that are not billed to the customer are included in sales and marketing expenses and were $2,261, $2,788 and $2,148, for the years ended December 31, 2020, 2019 and 2018, respectively. Cost of Revenue Cost of revenue consists primarily of products purchased from third-party suppliers, excess and obsolete inventory adjustments, inbound freight, and royalties. Our implants and instruments are manufactured to our specifications by third-party suppliers who meet our manufacturer qualifications standards. Our third-party manufacturers are required to meet Food and Drug Administration (the “FDA”), International Organization for Standardization and other country-specific quality standards. The majority of our implants and instruments are produced in the United States. Sales and Marketing Expenses Sales and marketing expenses primarily consist of commissions to our domestic and select international independent sales agencies and consignment distributors, as well as compensation, commissions, benefits and other related costs for personnel we employ. Commissions and bonuses are generally based on a percentage of sales. Our international independent stocking distributors purchase instrument sets and replenishment stock for resale, and we do not pay commissions or any other sales related costs for international sales to distributors. Advertising Costs Advertising costs consist primarily of print advertising, trade shows, and other related expenses. Advertising costs are expensed as incurred and are recorded as a component of sales and marketing expense. Advertising costs were $1,231, $1,422 and $978 for the years ended December 31, 2020, 2019 and 2018, respectively. Research and Development Costs Research and development costs are expensed as incurred. Our research and development expenses primarily consist of costs associated with engineering, product development, consulting services, outside prototyping services, outside research activities, materials, development and protection of our intellectual property portfolio, as well as other costs associated with development of our products. Research and development costs also include related personnel and consultants’ compensation expense. Stock-Based Compensation Prior to our IPO, we maintained an Amended and Restated 2007 Equity Incentive Plan (the “2007 Plan”) that provides for grants of options and restricted stock to employees, directors and associated third-party representatives of our company as determined by the Board of Directors. The 2007 Plan had authorized 1,585,000 shares for award. Immediately prior to our IPO, we adopted our 2017 Incentive Award Plan (the “2017 Plan”) which replaced the 2007 Plan. The 2017 Plan provides for grants of options and restricted stock to officers, employees, consultants or directors of our Company. The 2017 Plan has authorized 1,789,647 shares for award. Options holders, upon vesting, may purchase common stock at the exercise price, which is the estimated fair value of our common stock on the date of grant. Option grants generally vest immediately or over a three Restricted stock may not be transferred prior to the expiration of the restricted period. The restricted stock that has been granted under the 2007 Plan has restriction periods that generally last until the earlier of six years from the date of grant, or an initial public offering or change in control, as defined in the 2007 Plan. All restricted stock granted prior to May 2014 vested upon our IPO and the remaining grants under the 2007 Plan vested in April 2018. Generally under the 2017 plan, restricted stock vests over a three year period. We have elected to recognize the reversal of stock compensation expense when a restricted stock forfeiture occurs as opposed to estimating future forfeitures. We record the fair value of restricted stock at the grant date. Stock-based compensation is recognized ratably over the requisite service period, which is generally the restriction period for restricted stock. In determining the fair value of our common stock at the grant date for awards issued prior to our IPO, which is the basis for the fair value of stock based awards, we use the market approach, which is based on the assumption that the value of an asset is equal to the value of a substitute asset with the same characteristics. In using the market approach, we consider both the guideline public company method and the precedent transaction method. Given the absence of a public trading market for our common stock at that time, we exercise reasonable judgment and consider a number of objective and subjective factors to determine the best estimate of the fair value of our common stock, including: the preferences and dividends of our redeemable convertible preferred stock relative to those of our common stock; our operating results and financial conditions, including our level of available capital resources; equity market conditions affecting comparable public companies; general U.S. market conditions; and the lack of marketability of our common stock. Prior to our IPO, for restricted stock awards we applied a discount for lack of marketability to the fair value of common shares due to estimate the impact of valuing a minority interest in our Company as a closely held, non-public company with no liquid market for its shares. Foundation for Advancing Pediatric Orthopedics The Company may periodically make contributions to the Foundation for Advancing Pediatric Orthopedics (the "Foundation"). The Foundation was incorporated in 2018 exclusively for pediatric orthopedic research and education and qualifies under IRC 501(c)(3) as an exempt private foundation. The mission of the Foundation is to enhance the knowledge and experience, through education and research, of surgical trainees or practicing surgeons who are involved in helping children with orthopaedic disorders and injuries. The Foundation is a separate legal entity and is not a subsidiary of the Company; therefore, its results are not included in these consolidated financial statements. The Company contributed $325, $500 and $200 to the Foundation during the years ended December 31, 2020, 2019 and 2018, respectively. These contributions were recorded in general and administrative expenses. Comprehensive Income (Loss) Comprehensive income (loss) is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) includes foreign currency translation adjustments. Income Taxes We account 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, we determine 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. We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence. If we determine that we would be able to realize our deferred tax assets in the future in excess of their net recorded amount, we would make an adjustment to the valuation allowance. We record uncertain tax positions on the bases of a two-step process in which (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the positions and (2) for those tax positions that do not meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. Litigation and Contingencies Accruals for litigation and contingencies are reflected in the consolidated financial statements based on management’s assessment, including advice of legal counsel, of the expected outcome of litigation or other dispute resolution proceedings and/or the expected resolution of contingencies. Liabilities for estimated losses are accrued if the potential loss from any claim or legal proceeding is considered probable and the amount can be reasonably estimated. Significant judgment is required in both the determination of probability of loss and the determination as to whether the amount is reasonably estimable. Accruals are based only on information available at the time of the assessment due to the uncertain nature of such matters. As additional information becomes available, management reassesses potential liabilities related to pending claims and litigation and may revise its previous estimates, which could materially affect the Company’s results of operations in a given period. The Company recorded an accrual of $6,342 for legal settlements for the |
