Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Organization and Significant Accounting Policies | 1. Organization and Significant Accounting Policies Description of Business NuVasive, Inc. (the “Company” or “NuVasive”) was incorporated in Delaware on July 21, 1997, and began commercializing its products in 2001. • • • • • The Company has also invested in enabling technologies, including the development of capital equipment designed to further improve clinical, financial, and operational outcomes of spine surgery. The Company’s capital equipment portfolio currently consists of Lessray and the Pulse platform. Lessray is an image enhancement platform designed to reduce radiation exposure in the operating room by allowing surgeons to take low-quality, low-dose images and improve them to look like conventional full-dose images. Pulse integrates multiple enabling technologies within a single, expandable platform and is engineered to improve workflow, reduce variability, and increase the reproducibility of surgical outcomes. The Pulse platform’s modular architecture is designed to incorporate applications for neuromonitoring Selling and leasing of capital equipment do not make up a material portion of the Company’s total net sales. In addition to the Company’s procedurally integrated solutions for spine surgery, it also designs and sells expandable growing rod implant systems that can be non-invasively lengthened following implantation with precise, incremental adjustments via an external remote controller using magnetic technology called MAGnetic External Control (“MAGEC”), which allows for the minimally invasive treatment of early-onset and adolescent scoliosis. This technology is also the basis for the Company’s Precice limb lengthening system, which allows for the correction of long bone limb length discrepancy, as well as other products for treating specialized orthopedic procedures. In December 2019, a novel strain of coronavirus, which causes COVID-19, was identified. Due to the rapid and global spread of the virus, on March 11, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. To slow the proliferation of COVID-19, governments have implemented extraordinary measures, which include the mandatory closure of businesses, restrictions on travel and gatherings, and quarantine and physical distancing requirements. In addition, many government agencies in conjunction with hospitals and healthcare systems have, to varying degrees, deferred or suspended elective surgical procedures. While certain spine surgeries are deemed essential and certain surgeries, like in cases of trauma, cannot be delayed, the Company has seen and may continue to see a significant reduction in procedural volumes as hospital systems and/or patients elect to defer spine surgery procedures. As a result of these measures, the Company has experienced reductions in procedural volumes during 2020 and anticipates this trend may continue. Basis of Presentation and Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of the Company and its majority-owned or controlled subsidiaries, collectively referred to as either NuVasive or the Company. The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. When there is a portion of equity in an acquired subsidiary not attributable, directly or indirectly, to the respective parent entity, the Company records the fair value of the non-controlling interest at the acquisition date and classifies the amounts attributable to non-controlling interest separately in equity in the Company's Consolidated Financial Statements. Any subsequent changes in a parent's ownership interest while the parent retains its controlling financial interest in its subsidiary are accounted for as equity transactions. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has replaced the caption “Revenue” with “Net sales,” and the caption “Sales, marketing and administrative” with “Selling, general and administrative,” within the Consolidated Statements of Operations and corresponding changes have been made throughout this Annual Report to conform to this presentation. These updated captions have no impact on previously reported results of operations or financial position. Use of Estimates To prepare financial statements in conformity with generally accepted accounting principles (“GAAP”) accepted in the United States, management must make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Recent Accounting Pronouncements Not Yet Adopted In January 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force) The Company will adopt ASU 2020-01 on January 1, 2021, and does not expect a material impact to its Consolidated Financial Statements. In August 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40) 115.4 Recently Adopted Accounting Standards In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments – Credit Losses (“ASU 2016-13”), which changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. January 1, 2020 In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles – Goodwill and Other In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement In September 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangible – Goodwill and Other – Internal-Use Software In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which modifies Accounting Standard Codification 740 – Income Taxes (“ASC 740”). ASU 2019-12 enhances and simplifies various aspects of the income tax accounting guidance in ASC 740. This update is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, and early adoption is permitted. The Company elected to early adopt ASU 2019-12 in the quarter ended June 30, 2020. The Company applied the updated guidance for year-to-date losses in the Company’s interim period tax accounting on a prospective basis. The early adoption had no impact on the expected full year tax expense for 2020, but rather accelerated certain tax benefits to earlier quarters in 2020 that would otherwise have been limited under ASC 740. In March 2020, the FASB issued Accounting Standards Update No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting Revenue Recognition In accordance with Accounting Standards Codification 606 Revenue from Contracts with Customers (“ASC 606”), the Company recognizes revenue upon the transfer of goods or services to a customer at an amount that reflects the expected consideration to be received in exchange for those goods or services. The principles in ASC 606 are applied using the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) the Company satisfies its performance obligation(s). Specifically, revenue from the sale of implants, fixation products and disposables is generally recognized at an amount that reflects the expected consideration upon notice that the Company’s products have been used in a surgical procedure or upon shipment to a third-party customer assuming control of the products. Revenue from IONM services is recognized in the period the service is performed for the amount of consideration expected to be received. Revenue from the sale of surgical instrument sets is generally recognized upon receipt of a purchase order and the subsequent shipment to a customer who assumes control. In certain cases, the Company does offer the ability for customers to lease surgical instrumentation primarily on a non-sales type basis. Revenue from the sale or lease of is recognized when the Company transfers control to the customer, which is generally at the point when acceptance occurs that indicates customer acknowledgment of delivery or installation, depending on the terms of the arrangement Accounts Receivable and Related Valuation Accounts Accounts receivable in the accompanying Consolidated Balance Sheets are presented net of allowances for credit losses. The Company maintains an allowance for credit losses resulting from the inability of its customers, including hospitals, ambulatory surgery centers, and distributors, to make required payments. The allowance for credit losses is calculated quarterly, and is estimated on a region-by-region basis considering a number of factors including age of account balances, collection history, historical account write-offs, third party credit reports, identified trends, current economic conditions, and supportable forecasted economic expectations. The allowance is adjusted on a specific identification basis for certain accounts as well as pooling of accounts with similar characteristics. An increase in the provision for credit losses may be required when the financial condition of the Company’s customers or its collection experience deteriorates. An increase to the allowance for credit losses results in a corresponding charge to selling, general and administrative expenses. The Company has a diverse customer base and no single customer represented greater than ten percent of net sales or accounts receivable. Historically, the Company’s reserves have been adequate to cover credit losses. The Company's exposure to credit losses may increase if its customers are adversely affected by changes in healthcare laws, coverage and reimbursement, economic pressures or uncertainty associated with local or global economic recessions, disruption associated with the current COVID-19 pandemic, or other customer-specific factors. It is possible that there could be a material adverse impact from potential adjustments of the carrying amount of trade receivables as customers’ cash flows are impacted by their response to the COVID-19 pandemic and the deferral of elective surgical procedures. The following table summarizes the changes in the allowance for credit losses: (in thousands) December 31, 2020 Allowance for credit losses at January 1, 2020 $ 9,423 Current-period provision for expected losses 1,079 Write-offs charged against the allowance (1,305 ) Recoveries of amounts previously written off 220 Changes resulting from foreign currency fluctuations 229 Allowance for credit losses at end of period $ 9,646 In addition, the Company establishes a liability for estimated sales returns and a reserve for price adjustments that are recorded as a reduction to net sales. The liability and reserve are maintained to account for the future product returns and price adjustments of products sold in the current period. Concentration of Credit Risk and Significant Customers Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of cash and cash equivalents, marketable securities and accounts receivable. The Company limits its exposure to credit loss by placing its cash and investments with high credit quality financial institutions. Additionally, the Company has established guidelines regarding diversification of its investments and their maturities, which are designed to maintain principal and maximize liquidity. The Company has a diverse customer base and no single customer represented greater than ten percent of sales or accounts receivable for any of the periods presented. Fair Value of Financial Instruments The Company’s financial instruments consist principally of cash and cash equivalents, marketable securities, restricted investments, derivatives, contingent consideration liabilities, accounts receivable, accounts payable, accrued expenses, and Senior Convertible Notes. The Company measures certain assets and liabilities in accordance with authoritative guidance which requires fair value measurements to be classified and disclosed in one of the following three categories: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the years presented. Cash and Cash Equivalents The Company considers all highly liquid investments that are readily convertible into cash and have an original maturity of three months or less at the time of purchase to be cash equivalents. Inventory, net Net inventory as of December 31, 2020 consisted of $285.4 million of finished goods, $7.3 million of work in progress and $7.9 million of raw materials. Net inventory as of December 31, 2019 consisted of $298.7 million of finished goods, $6.4 million of work in progress and $7.3 million of raw materials. Finished goods primarily consists of specialized implants, fixation products and disposables and are stated at the lower of cost or net realizable value determined by utilizing a standard cost method, which includes capitalized variances, which approximates the weighted average cost. Work in progress and raw materials represent the underlying material, and labor for work in progress, that ultimately yield finished goods upon completion and are subject to lower of cost or net realizable value. The Company reviews the components of its inventory on a periodic basis for excess and obsolescence and adjusts inventory to its net realizable value as necessary. The Company records an inventory reserve for estimated excess and obsolete inventory based upon historical turnover and assumptions about future demand for its products and market conditions, such as product life cycles and timing of the introduction and development of new or enhanced products One of the Company’s strategic objectives is to continue to rapidly develop and commercialize new products and product enhancements For the year ended December 31, 2020 and 2019, the Company recorded a reserve for excess and obsolete inventory of $48.9 million and $14.0 million, respectively. The increase is primarily attributable to updates to the Company’s estimates and assumptions about future product demand and product life cycles which have been affected by multiple factors, including the COVID-19 pandemic and general market conditions Goodwill and Intangible Assets The Company’s goodwill represents the excess of the cost over the fair value of net assets acquired from its business combinations. The determination of the value of goodwill and intangible assets arising from business combinations and asset acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired, including capitalized Intangible assets acquired in a business combination that are used for in-process research and development activities are considered indefinite lived until the completion or abandonment of the associated research and development efforts. Upon reaching the end of the relevant research and development project, the Company will amortize the acquired IPR&D over its estimated useful life or expense the acquired in-process research and development should the research and development project be unsuccessful with no future alternative use. Goodwill and IPR&D are not amortized; however, they are assessed for impairment using fair value measurement techniques on an annual basis or more frequently if facts and circumstance warrant such a review. The goodwill or IPR&D are considered to be impaired if the Company determines that the carrying value of the reporting unit or IPR&D exceeds its respective fair value. The Company performs its goodwill impairment analysis at the reporting unit level, which aligns with the Company’s reporting structure and availability of discrete financial information. The Company performs its annual impairment analysis by either comparing a reporting unit’s estimated fair value to its carrying amount or doing a qualitative assessment of a reporting unit’s fair value from the last quantitative assessment to determine if there is potential impairment. The Company may do a qualitative assessment when the results of the previous quantitative test indicated the reporting unit’s estimated fair value was significantly in excess of the carrying value of its net assets and it does not believe there have been significant changes in the reporting unit’s operations that would significantly decrease its estimated fair value or significantly increase its net assets. If a quantitative assessment is performed the evaluation includes management estimates of cash flow projections based on internal future projections and/or use of a market approach by looking at market values of comparable companies . Key assumptions for these projections include net sales growth, future gross and operating margin growth, and its weighted cost of capital and terminal growth rates. The net sales and margin growth is based on increased sales of new and existing products as the Company maintains investments in research and development. Additional assumed value creators may include increased efficiencies from capital spending. The resulting cash flows are discounted using a weighted average cost of capital. Operating mechanisms and requirements to ensure that growth and efficiency assumptions will ultimately be realized are also considered in the evaluation, including timing and probability of regulatory approvals for Company products to be commercialized. The Company’s market capitalization is also considered as a part of its analysis. The Company’s annual evaluation for impairment of goodwill consists of one reporting unit. In accordance with the Company’s policy, the Company completed its most recent annual evaluation for impairment as of October 1, 2020 using the qualitative assessment and determined that no impairment existed. In addition, no indicators of impairments were noted through and consequently, no impairment charge has been recorded during the year. Intangible assets with a finite life, such as acquired technology, customer relationships, manufacturing know-how, licensed technology, supply agreements and certain trade names and trademarks, are amortized on a straight-line basis over their estimated useful life, ranging from 2 to 17 years. In determining the useful lives of intangible assets, the Company considers the expected use of the assets and the effects of obsolescence, demand, competition, anticipated technological advances, changes in surgical techniques, market influences and other economic factors. For technology based intangible assets, the Company considers the expected life cycles of products which incorporate the corresponding technology. Trademarks and trade names that are related to products are assigned lives consistent with the period in which the products bearing each brand are expected to be sold. The Company evaluates its intangible assets with finite lives for indications of impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that could trigger an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of the Company’s use of the acquired assets or the strategy for the Company’s overall business or significant negative industry or economic trends. If this evaluation indicates that the value of the intangible asset may be impaired, the Company makes an assessment of the recoverability of the net carrying value of the asset over its remaining useful life. If this assessment indicates that the intangible asset is not recoverable, based on the estimated undiscounted future cash flows of the technology over the remaining amortization period, the Company reduces the net carrying value of the related intangible asset to fair value and may adjust the remaining amortization period. See Note 2 to the Consolidated Financial Statements included in this Annual Report for further disclosure on goodwill and intangible assets. Property and Equipment Property and equipment are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, ranging from 2 to 20 years. The Company depreciates leasehold improvements over their estimated useful lives or the term of the applicable lease, whichever is shorter. Leased property meeting certain financing lease criteria is capitalized under property and equipment, and the net present value of the related lease payments is recorded as a liability. Amortization of assets under financing leases is recorded using the straight-line method over the shorter of the estimated useful lives or the lease terms. The Company reviews property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss would be recognized when estimated future undiscounted cash flows relating to the asset are less than its carrying amount. An impairment loss is measured as the amount by which the carrying amount of an asset exceeds its fair value. Income Taxes The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Tax law and rate changes are reflected in income in the period such changes are enacted. The Company includes interest and penalties related to income taxes, including unrecognized tax benefits, within income tax expense. The Company’s income tax returns are based on calculations and assumptions that are subject to examination by the Internal Revenue Service and other tax authorities. In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of comp lex tax regulations. The Company recognize s liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believe s it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of examinations by tax authorities in determining the adequacy of its provision for income taxes. The Company continually assess es the likelihood and amount of potential revisions and adjusts the income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision become known. Significant judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities and the valuation allowance recorded against net deferred tax assets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available positive and negative evidence. Factors reviewed include projections of pre-tax book income for the foreseeable future, determination of cumulative pre-tax book income after permanent differences, earnings history, and reliability of forecasting. Based on the Company’s review, it concluded that it was more likely than not that it would be able to realize the future benefits of its domestic and foreign deferred tax assets, with the exceptions of California, Malta, Mexico, Brazil and Colombia. This conclusion was based on historical and projected operating performance, as well as the Company’s expectation that its operations will generate sufficient taxable income in future periods to realize the tax benefits associated with the deferred tax assets well within the statutory carryover periods. Due to low state apportionment, large net operating losses and the generation of sizeable research credits in California, the Company concluded that it is not more likely than not that it will be able to utilize its California deferred tax assets. Therefore, the Company has maintained a full valuation allowance on its California deferred tax assets as of December 31, 2020. Due to a history of losses in Malta, Brazil, Mexico and Colombia, and the lack of alternative sources of future taxable income, the Company has established a full valuation allowance against these entities’ deferred tax assets as of December 31, 2020. The Company will continue to assess the need for a valuation allowance on its deferred tax assets by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the statement of operations for the period that the adjustment is determined to be required. See Note 10 to the Consolidated Financial Statements included in this Annual Report for further discussion on income taxes. Loss Contingencies An estimated loss contingency is accrued and disclosed in the Company’s financial statements if it is probable or disclosed if it is reasonably possible that a liability has been incurred and the amount of the loss can be reasonably estimated. Based on the Company’s assessment, it has adequately accrued an amount for contingent liabilities currently in existence. The Company does not accrue amounts for liabilities that it does not believe are probable and only discloses those matters it considers material to its overall financial position. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded. The Company is involved in a number of legal actions arising in the normal course of business. The outcomes of these legal actions are not within the Company’s complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages as well as other relief, including injunctions barring the sale of products that are the subject of the lawsuit, that could require significant expenditures or result in lost net sales. Litigation is inherently unpredictable, and unfavorable resolutions could occur. As a result, assessing contingencies is highly subjective and requires judgment about future events. The amount of ultimate loss may exceed the Company’s current accruals, and it is possible that its cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies. See Note 12 to the Consolidated Financial Statements included in this Annual Report for further discussion on legal proceedings and investigations. Comprehensive Income Comprehensive income is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income includes net of tax, unrealized gains or losses on the Company’s marketable debt securities and foreign currency translation adjustments. The cumulative translation adjustments included in accumulated other comprehensive loss were $7.6 million, $9.4 million, and $8.6 million at December 31, 2020, 2019, and 2018, respectively. Research and Development Research and development costs are expensed as incurred. To the extent the Company purchases research and development assets with a future alternative use the Company will capitalize and amortize the assets over its useful life. Product Shipment Costs Product shipment costs, included in selling, general and administrative expense in the accompanying Consolidated Statements of Operations, were $27.4 million, $27.7 million, and $25.4 million for the years ended December 31, 2020, 2019, and 2018, respectively. The majority of the Company’s shipping costs are associated with providing instrument sets to hospitals for use in individual surgical procedures. Amounts billed to customers for shipping and handling of products are reflected in net sales and are not material for any period presented. Business Transition Costs The Company incurs certain costs related to acquisition, integration and business transition activities, which include severance, relocation, consulting, leasehold exit costs, third-party merger and acquisition costs, contingent consideration fair value adjustments and other costs directly associated with such activities. Contingent consideration is accrued based on the fair value of the expected payment, and such accruals are subject to increase or decrease based on the assessment of the likelihood that the contingent milestones will be achieved resulting in payment. If an accrual for contingent consideration decreases during a particular period, it results in a reduction of costs during such period. During the year ended December 31, 2020, the Company recorded $10.9 million of costs related to acquisition, integration and business transition activities, which included $2.3 million of fair value adjustments on contingent consideration liabilities associated with the Company’s 2018, 2017 and 2016 acquisitions. During the year ended December 31, 2019, the Company recorded a reduction of costs of $(2.0) million related to acquisition, integration and business transition activities, which included $(6.3) million of fair value adjustments on contingent consideration liabilities associated with the Company’s 2018, 2017 and 2016 acquisitions. During the year ended December 31, 2018, the Company recorded $11.5 million of costs related to acquisition, integration and business transition activities, which included $(1.5) million of fair value adjustments on contingent consideration liabilities associated with the Company’s 2018, 2017 and 2016 acquisitions. Stock-based Compensation Stock-based compensation expense for equity-classified awards, principally related to restricted stock units (“RSUs”) and performance restricted stock units (“PRSUs”), is measured at the grant date based on the estimated fair value of the award. The fair value of equity instruments that are expected to vest is recognized and amortized over the requisite service period. The Company has granted awards with up to five year graded or cliff vesting terms . The fair value of RSUs including PRSUs with pre-de |

Depreciation expense was $85.9 million, $80.8 million, and $75.4 million for the years ended December 31, 2020, 2019 and 2018, respectively. The Company depreciates leasehold improvements over their estimated useful lives or the term of the applicable lease, whichever is shorter. Capitalized software costs include only those direct costs associated with the actual development or acquisition of computer software. At December 31, 2020 and 2019, the Company had $57.6 million and $51.7 million in unamortized capitalized software costs, respectively. Amortization expense related to capitalized software costs was $10.4 million, $10.4 million and $10.6 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Marketable Securities | 3. Marketable Securities Short-Term Marketable Securities The Company invests in available-for-sale marketable debt securities consisting of corporate notes and commercial paper. The Company has the ability, if necessary, to liquidate without penalty any of its marketable debt securities to meet its liquidity needs in the next 12 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 . As of December 31, 2020, the Company’s outstanding marketable debt securities all have contractual maturities due within one year. The carrying value and amortized cost of the Company’s marketable debt securities, summarized by major security type, consisted of the following: ( in thousands Amortized Cost Gross Unrealized Gains Gross Unrealized Losses Fair Value December 31, 2020: Debt securities, available for sale: Corporate notes $ 54,197 $ 6 $ (15 ) $ 54,188 Commercial paper 118,932 25 — 118,957 Total debt securities, available for sale $ 173,129 $ 31 $ (15 ) $ 173,145 At each reporting date, the Company performs an evaluation of impairment to determine if any unrealized losses are the result of credit losses. Impairment is assessed at the individual security level. Factors considered in determining whether a loss resulted from a credit loss or other factors include the Company’s intent and ability to hold the investment until the recovery of its amortized cost basis, the extent to which the fair value is less than the amortized cost basis, the length of time and extent to which fair value has been less than the cost basis, the financial condition of the issuer, any historical failure of the issuer to make scheduled interest or principal payments, any changes to the rating of the security by a rating agency, any adverse legal or regulatory events affecting the issuer or issuer’s industry, and any significant deterioration in economic conditions. The credit-related portion of unrealized losses, and any subsequent improvements, are recorded in interest income in the Consolidated Statement of Operations through an allowance for credit losses. Unrealized gains and losses that are not credit-related are included in accumulated other comprehensive loss. Unrealized losses on available-for-sale debt securities as of December 31, 2020 were not significant and were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Accordingly, the Company has not recorded an allowance for credit losses with these investments. |

Financial Instruments and Fair Value Measurements | 4. Financial Instruments and Fair Value Measurements Foreign Currency and Derivative Financial Instruments The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities, and average exchange rates during each reporting period for results of operations. Some of the Company’s reporting entities conduct a portion of their business in currencies other than the entity’s functional currency. These transactions give rise to receivables and payables that are denominated in currencies other than the entity’s functional currency. The value of these receivables and payables is subject to changes in currency exchange rates from the point at which the transactions are originated until the settlement in cash. Both realized and unrealized gains and losses in the value of these receivables and payables are included in the determination of net income. Net currency exchange losses, which include gains and losses from derivative instruments, were $4.2 million, $0.8 million and $3.7 million for the years ended December 31, 2020, 2019 and 2018, respectively, and are included in other (expense) income, net in the Consolidated Statements of Operations. To manage foreign currency exposure risks, the Company uses derivatives for activities in entities that have short-term intercompany receivables and payables denominated in a currency other than the entity’s functional currency. Fair Value Measurements Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the periods presented. The fair values of the Company’s assets and liabilities, including cash equivalents, marketable debt securities, derivatives, and contingent consideration are measured at fair value on a recurring basis . December 31, 2020 December 31, 2019 Cash equivalents and marketable debt securities are determined under the fair value categories as follows: Quoted Price in Significant Other Significant Active Market Observable Inputs Unobservable ( in thousands Total (Level 1) (Level 2) Inputs (Level 3) December 31, 2020: Cash equivalents: Money market funds $ 725,108 $ 725,108 $ — $ — Commercial paper 35,996 — 35,996 — Total cash equivalents 761,104 725,108 35,996 — Debt securities, available for sale: Corporate notes 54,188 — 54,188 — Commercial paper 118,957 — 118,957 — Total debt securities, available for sale 173,145 — 173,145 — Total assets measured at fair value $ 934,249 $ 725,108 $ 209,141 $ — December 31, 2019: Cash equivalents: Money market funds $ 151,750 $ 151,750 $ — $ — Total cash equivalents $ 151,750 $ 151,750 $ — $ — The carrying amounts of certain financial instruments such as cash and cash equivalents, accounts receivable, prepaid expenses, other current assets, accounts payable, accrued expenses, and other current liabilities as of December 31, 2020 and December 31, 2019 approximate their related fair values due to the short-term maturities of these instruments. The fair value of certain financial instruments was measured and classified within Level 1 of the fair value hierarchy based on quoted prices. Fair Value of Senior Convertible Notes The fair value, based on a quoted market price (Level 1), of the Company’s outstanding $650.0 million principal amount of Senior Convertible Notes due 2021 at December 31, 2020 and December 31, 2019 was approximately $651.6 million and $869.3 million, respectively. The fair value, based on a quoted market price (Level 1), of the Company’s outstanding $450.0 million principal amount of Senior Convertible Notes due 2023 at December 31, 2020 was approximately $461.9 million. The fair value, based on a quoted market price (Level 1), of the Company’s outstanding $450.0 million principal amount of Senior Convertible Notes due 2025 at December 31, 2020 was approximately $436.7 million. . Fair Value of Convertible Note Hedge and Embedded Conversion Derivatives On June 1, 2020, the Company issued $450.0 million principal amount of 1.00% Senior Convertible Notes due 2023 (the “2023 Notes”). The 2023 Notes were initially required to be settled in cash as the Company did not have enough available shares and was unable to reserve the maximum number of shares issuable under the 2023 Notes (“sufficient reserved shares”). On September 10, 2020, the Company held a Special Meeting of Stockholders and received stockholder approval to amend the Company’s Restated Certificate of Incorporation to increase the number of shares of its common stock authorized for issuance from 120,000,000 shares to 150,000,000 shares. As a result of the increase in the number of shares of the Company’s common stock authorized for issuance, as of September 10, 2020 and as of December 31, 2020, the Company had sufficient reserved shares and therefore may settle conversions of the 2023 Notes in cash, stock, or a combination thereof, solely at the Company’s discretion. In accordance with authoritative guidance, the cash conversion feature of the 2023 Notes requires bifurcation from the 2023 Notes and was initially accounted for as a derivative liability (“Embedded Conversion Derivative”), which was included in long-term liabilities in the Company’s Consolidated Balance Sheet. On September 10, 2020, and in accordance with authoritative literature, the was marked to fair value and reclassified to stockholders’ equity. In connection with the issuance of the 2023 Notes, the Company entered into convertible note hedge transactions (the “2023 Hedge”) entitling the Company . In accordance with authoritative literature, the was marked to fair value and reclassified to stockholders’ equity. Prior to their reclassification to stockholders’ equity on September 10, 2020, were classified as Level 3 of the fair value hierarchy as these derivative instruments were not actively traded and were valued using significant unobservable inputs. The following tables set forth the changes in the estimated fair value for the Company’s derivative assets and liabilities measured using significant unobservable inputs (Level 3): ( in thousands 2020 Assets: Fair value measurement at January 1 $ — Derivative assets recorded in connection with the 2023 Hedge 69,525 Change in fair value measurement (32,233 ) Derivative asset reclassified to stockholders’ equity (37,292 ) Fair value measurement at December 31 $ — ( in thousands 2020 Liabilities: Fair value measurement at January 1 $ — Derivative liability recorded in connection with the 2023 Notes 57,224 Change in fair value measurement (19,932 ) Derivative liability reclassified to stockholders’ equity (37,292 ) Fair value measurement at December 31 $ — During 2020, the fair value measurement was determined utilizing a Black-Scholes valuation model. Key assumptions used in the valuation included risk-free interest rates, volatility, and expected term. The Company recorded the change in fair value measurement associated with its derivative assets and liabilities in other (expense) income, net in the Consolidated Statement of Operations. Contingent Consideration Liabilities The fair value of contingent consideration liabilities assumed in business combinations is recorded as part of the purchase price consideration of the acquisition, and is determined using a discounted cash flow model or probability simulation model. The significant inputs of such models are not observable in the market, such as certain financial metric growth rates, volatility rates, projections associated with the applicable milestone, the interest rate, and the related probabilities and payment structure in the contingent consideration arrangement. Fair value adjustments to contingent consideration liabilities are recorded through operating expenses in the Consolidated Statement of Operations. Contingent consideration arrangements assumed by an asset purchase will be measured and accrued when such contingency is resolved. The recurring Level 3 fair value measurements of contingent consideration liabilities associated with commercial sales milestones include the following significant unobservable inputs as of December 31, 2020: 2020 Valuation Techniques Discounted cash flow, Monte Carlo Discount Rate Range 2.8% - 4.0% Weighted Average Discount Rate 3.6% Expected Years 2021 - 2024 Contingent consideration liabilities were $37.0 million December 31, 2020 December 31, 2019 The following table sets forth the changes in the estimated fair value of the Company’s liabilities measured on a recurring basis using significant unobservable inputs (Level 3): ( in thousands 2020 2019 Fair value measurement at January 1 $ 42,559 $ 50,410 Change in fair value measurement 2,420 (6,297 ) Contingent consideration paid or settled (7,938 ) (1,435 ) Changes resulting from foreign currency fluctuations — (119 ) Fair value measurement at December 31 $ 37,041 $ 42,559 Non-financial assets and liabilities measured on a nonrecurring basis Certain non-financial assets and liabilities are measured at fair value, usually with Level 3 inputs including the discounted cash flow method or cost method, on a nonrecurring basis in accordance with authoritative guidance. These include items such as nonfinancial assets and liabilities initially measured at fair value in a business combination and non-financial long-lived assets measured at fair value for an impairment assessment. In general, non-financial assets, including goodwill, intangible assets and property and equipment, are measured at fair value when there is an indication of impairment and are recorded at fair value only when any impairment is recognized. The carrying values of the Company’s financing lease obligations approximated their estimated fair value as of December 31, 2020 and 2019. During the year ended December 31, 2019, the Company recorded a loss of $4.8 million on a strategic investment. The loss was recorded in other (expense) income, net in the Consolidated Statement of Operations included in this Annual Report. During the year ended December 31, 2018, the Company expensed $8.9 million for a purchased in-process research and development asset which had no future alternative use. The Company also recorded a net loss of $3.8 million on strategic investments during the year ended December 31, 2018.

Business Combination Description [Abstract] | |
Business Combinations | 5. Business Combinations The Company recognizes the assets acquired, liabilities assumed, and any non-controlling interest at fair value at the date of acquisition. Certain acquisitions contained contingent consideration arrangements that required the Company to assess the acquisition date fair value of the contingent consideration liabilities, which was recorded as part of the purchase price allocation of the acquisition, with subsequent fair value adjustments to the contingent consideration recorded in the Consolidated Statements of Operations. to the Consolidated Financial Statements included in this Annual Report for further discussion on contingent consideration liabilities. Acquisitions The Company has completed acquisitions that were not considered material, individually or collectively, to the overall Consolidated Financial Statements during the periods presented. These acquisitions have been included in the Consolidated Financial Statements from the respective dates of acquisition. The Company does not believe that collectively the acquisitions made during the periods presented are material to the overall financial statements. The Company finalizes the purchase price allocation of the assets and liabilities subject to valuation obtained in business combinations within one year from the acquisition date. While the Company does not expect material changes from the initial outcome of the valuation, certain assumptions and findings made at the date of acquisition could result in changes in the purchase price allocation. Variable Interest Entities The Company provides IONM services through various subsidiaries, which conduct business as NuVasive Clinical Services. In providing IONM services to surgeons and healthcare facilities across the United States, the Company maintains contractual relationships with several physician practices (“PCs”). In accordance with authoritative guidance, the Company has determined that the PCs are variable interest entities and therefore, the accompanying Consolidated Financial Statements include the accounts of the PCs from the date of acquisition. During the periods presented, the results of the PCs were immaterial to the Company’s financial statements. The creditors of the PCs have claims only to the assets of the PCs, which are not material, and the assets of the PCs are not available to the Company. |

The interest expense recognized on the 2021 Notes during the year ended December 31, 2020 Prior to September 15, 2020, holders could have converted their 2021 Notes only under the following conditions: (a) during any calendar quarter beginning June 30, 2016, if the reported sale price of the Company's common stock for at least 20 days out of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter was greater than 130% of the conversion price on each applicable trading day; (b) during the five business day period in which the trading price of the 2021 Notes fell below 98% of the product of (i) the last reported sale price of the Company's common stock and (ii) the conversion rate on that date; and (c) upon the occurrence of specified corporate events, as defined in the 2021 Notes. From September 15, 2020 and until the close of business on the second scheduled trading day immediately preceding March 15, 2021, holders may convert their 2021 Notes at any time (regardless of the foregoing circumstances). The 2021 Notes can no longer be redeemed by the Company. The Company previously had the ability to redeem the 2021 Notes, at its option, in whole or in part beginning on March 20, 2019 until the close of business on the business day immediately preceding September 15, 2020 if the last reported sale price of the Company’s common stock had been at least 130% of the conversion price then in effect for at least 20 trading days during any 30 consecutive trading day period ending on, and including, the trading day immediately preceding the date on which the Company delivers written notice of a redemption. As of September 15, 2020, holders may convert their 2021 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. As a result, the 2021 Notes are considered redeemable as of December 31, 2020. A portion of the equity component that was recorded upon the issuance of the 2021 Notes was reclassified to temporary equity in the Consolidated Balance Sheet. Such amount was determined based on the cash consideration to be paid upon conversion and the carrying amount of the debt. The reclassification into temporary equity as of December 31, 2020 was $4.7 million based on the 2021 Notes principal of $650.0 million and the carrying value of $645.3 million. 2021 Hedge In connection with the offering of the 2021 Notes, the Company entered into the hedge transaction with the initial purchasers of the 2021 Notes and/or their affiliates (the "2021 Counterparties") entitling the Company to purchase up to 10,865,270 shares of the Company's common stock at an initial stock price of $59.82 per share, each of which is subject to adjustment. The cost of the 2021 Hedge was $111.2 million and accounted for as an equity instrument by recognizing $111.2 million in additional paid-in-capital during 2016. The 2021 Hedge will expire on March 15, 2021. The 2021 Hedge is expected to reduce the potential equity dilution upon conversion of the 2021 Notes if the daily volume-weighted average price per share of the Company's common stock exceeds the strike price of the 2021 Hedge. An assumed exercise of the 2021 Hedge by the Company is considered anti-dilutive since the effect of the inclusion would always be anti-dilutive with respect to the calculation of diluted earnings per share. 2021 Warrants The Company sold warrants to the 2021 Counterparties to acquire up to 10,865,270 shares of the Company’s common stock. The 2021 Warrants will expire on various dates from June 2021 through December 2021 and may be settled in cash or net shares. It is the Company's current intent and policy to settle all conversions in shares of the Company’s common stock. The Company received $44.9 million in cash proceeds from the sale of the 2021 Warrants, which was recorded in additional paid-in-capital. The 2021 Warrants could have a dilutive effect on the Company's earnings per share to the extent that the price of the Company's common stock during a given measurement period exceeds the strike price of the 2021 Warrants, which is $80.00 per share. The Company uses the treasury share method for assumed conversion of its 2021 Warrants to compute the weighted average common shares outstanding for diluted earnings per share. 1.00% Senior Convertible Notes due 2023 In June 2020, the Company issued $450.0 million principal amount of unsecured Senior Convertible Notes with a stated interest rate of 1.00% and a maturity date of June 1, 2023. The net proceeds from the offering, after deducting initial purchasers’ discounts and costs directly related to the offering, were approximately $436.7 million. The 2023 Notes were initially required to be settled in cash as the Company did not have sufficient reserved shares. On September 10, 2020, the Company held a Special Meeting of Stockholders and received stockholder approval to amend the Company’s Restated Certificate of Incorporation to increase the number of shares of its common stock authorized for issuance from 120,000,000 shares to 150,000,000 shares. As a result of the increase in the number of shares of the Company’s common stock authorized for issuance, as of September 10, 2020 and as of December 31, 2020, the Company had sufficient reserved shares and therefore may settle conversions of the 2023 Notes in cash, stock, or a combination thereof, solely at the Company’s discretion. It is the Company’s current intent and policy to settle all conversions through combination settlement, which involves satisfying the principal amount outstanding with cash and any note conversion value over the principal amount in shares of the Company’s common stock. The initial conversion rate of the 2023 Notes is 11.8778 shares per $1,000 principal amount, which is equivalent to a conversion price of approximately $84.19 per share, subject to adjustments. In addition, following certain corporate events that occur prior to the maturity date, the Company will increase the conversion rate for a holder who elects to convert its 2023 Notes in connection with such a corporate event in certain circumstances. The Company also entered into transactions for a convertible notes hedge and warrants concurrently with the issuance of the 2023 Notes. As discussed in Note 4, the Embedded Conversion Derivative requires bifurcation from the 2023 Notes and was initially accounted for as a liability, which was included in long-term liabilities in the Company’s Consolidated Balance Sheet. The fair value of the 2023 Notes Embedded Conversion Derivative at the time of issuance of the 2023 Notes was $57.2 million, and was recorded as the original debt discount for purposes of accounting for the debt component of the 2023 Notes. On September 10, 2020, in accordance with authoritative literature, the was marked to fair value and reclassified to stockholders’ equity, which resulted in recognizing $37.3 million in additional paid-in-capital during the year ended December 31, 2020. The interest expense recognized on the 2023 Notes during the year ended December 31, 2020 includes $2.6 million, $10.4 million and $2.2 million for the contractual coupon interest, the accretion of the debt discount and the amortization of the debt issuance costs, respectively. The effective interest rate on the 2023 Notes is 6.8%, which includes the interest on the notes, amortization of the debt discount and debt issuance costs. Interest on the 2023 Notes began accruing upon issuance and is payable semi-annually. Prior to February 1, 2023, holders may convert their 2023 Notes only under the following conditions: (a) during any calendar quarter commencing after the calendar quarter ending on September 30, 2020 (and only during such calendar quarter), if the last reported sale price of the Company’s common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (b) during the five business day period after any five consecutive trading day period (the “measurement period”) in which the trading price of the 2023 Notes per $1,000 principal amount of notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on such trading day; or (c) upon the occurrence of specified corporate events, as defined in the 2023 Notes. On or after February 1, 2023, until the close of business on the second scheduled trading day immediately preceding June 1, 2023, holders may convert their 2023 Notes at any time, regardless of the foregoing conditions. The Company may not redeem the 2023 Notes prior to the maturity date and no principal payments are due on the 2023 Notes prior to maturity. Other than restrictions relating to certain fundamental changes and consolidations, mergers or asset sales and customary anti-dilution adjustments, the 2023 Notes do not contain any financial covenants and do not restrict the Company from conducting significant restructurings, paying dividends or issuing or repurchasing any of its other securities. As of December 31, 2020, the Company is unaware of any current events or market conditions that would allow holders to convert the 2023 Notes. 2023 Hedge In connection with the sale of the 2023 Notes, the Company entered into privately negotiated call option transactions with certain dealers, which included affiliates of certain of the initial purchasers of the 2023 Notes and other financial institutions (the “2023 Counterparties”), entitling the Company to purchase up to 5,345,010 shares of the Company’s common stock at an initial stock price of $84.19 per share, each of which is subject to adjustment. The 2023 Hedge was initially required to be settled in cash as the Company did not have sufficient reserved shares with respect to the 2023 Notes. As a result, the 2023 Hedge was accounted for as a derivative asset, which was included in long-term assets in the Company’s Consolidated Balance Sheet. The cost of the 2023 Hedge was $69.5 million. In accordance with authoritative literature, the Convertible Note Hedge Derivative was marked to fair value and reclassified to stockholders’ equity, which resulted in recognizing a reduction of $37.3 million in additional paid-in-capital during the year ended December 31, 2020. The 2023 Hedge will expire on the second scheduled trading day immediately preceding June 1, 2023. The 2023 Hedge is expected to reduce the potential equity dilution upon conversion of the 2023 Notes if the daily volume-weighted average price per share of the Company’s common stock exceeds the strike price of the 2023 Hedge. An assumed exercise of the 2023 Hedge by the Company is considered anti-dilutive since the effect of the inclusion would always be anti-dilutive with respect to the calculation of diluted earnings per share. 2023 Warrants In connection with the sale of the 2023 Notes, the Company sold warrants to the 2023 Counterparties (the “2023 Warrants”) to acquire up to 5,345,010 shares of the Company’s common stock. The 2023 Warrants initially limited the amount of shares the Company was required to reserve for issuance under the 2023 Warrants to an aggregate of 3,093,500 shares of the Company’s common stock, subject to adjustment upon the Company having a sufficient amount of authorized and unissued shares which are not reserved for other transactions. As a result of the Company receiving stockholder approval to increase the number of shares of the Company’s common stock authorized for issuance on September 10, 2020, the Company subsequently entered into amendment agreements with each of the 2023 Counterparties to increase the number of authorized shares of the Company’s common stock required to be reserved under the 2023 Warrants to the aggregate amount of 6,948,512 shares. The 2023 Warrants will expire on various dates from September 2023 through November 2023 and may be settled in net shares or cash, subject to certain conditions.

Revolving Senior Credit Facility In February 2020, the Company entered into a Second Amended and Restated Credit Agreement (the “2020 Credit Agreement”) for a revolving senior credit facility (the “2020 Facility”), which replaced the previous Amended and Restated Credit Agreement the Company had entered into in April 2017. The 2020 Credit Agreement was further amended in May 2020 to, among other things, provide additional flexibility in determining the financial covenant leverage ratios for the second and third fiscal quarters of 2020 and to adjust certain margin and benchmark rates used to determine interest under the 2020 Facility. The 2020 Credit Agreement provides for secured revolving loans, multicurrency loan options and letters of credit in an aggregate amount of up to $ 550.0 and includes a sublimit of $50.0 million for standby letters of credit, a sublimit of $250.0 million for multicurrency borrowings, and a sublimit of $5.0 million for swingline loans.

Borrowings under the 2020 Facility bear interest, at the Company’s option, at a rate equal to an applicable margin plus: (a) the applicable Eurocurrency Rate (as defined in the 2020 Credit Agreement), or (b) a base rate determined by reference to the highest of (1) the federal funds effective rate plus 0.50%, (2) the Bank of America prime rate, and (3) the Eurocurrency Rate for an interest period of one month plus 1.00%. The margin for the 2020 Facility ranges, based on the Company’s consolidated total net leverage ratio, from 0.50% to 1.25% in the case of base rate loans and from 1.50% to 2.25% in the case of Eurocurrency Rate loans. The 2020 Facility includes an unused line fee ranging, based on the Company’s consolidated total net leverage ratio, from 0.35% to 0.50% per annum on the revolving commitment. The 2020 Credit Agreement contains affirmative, negative, permitted acquisition and financial covenants, and events of default customary for financings of this type. The financial covenants require the Company to maintain a consolidated interest coverage ratio and certain consolidated leverage ratios, which are measured on a quarterly basis. The 2020 Facility grants the lenders preferred first priority liens and security interests in capital stock, intercompany debt and all of the present and future property and assets of the Company and each guarantor. The Company is currently in compliance with the 2020 Credit Agreement covenants. |

Commitments | 7. Commitments 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 records the associated lease liability and corresponding right-of-use asset upon commencement of the lease using a discount rate based on a credit-adjusted secured 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 as long-term assets. Right-of-use assets for financing leases are recorded within property and equipment, net in the Consolidated Balance Sheet. Leases with an initial term of 12 months or less are not recorded in the Consolidated Balance Sheet. The Company recognizes lease expense on a straight-line basis over the lease term. In connection with certain operating leases, the Company has security deposits recorded and maintained as restricted cash totaling $1.5 million as of December 31, 2020 The Company leases office and storage facilities and equipment under various operating and financing lease agreements. The initial terms of these leases range from 1 to 17 years and generally provide for periodic rent increases, and renewal and termination options The Company’s lease agreements do not contain any material variable lease payments, residual value guarantees or material restrictive covenants. Certain leases require the Company to pay taxes, insurance and maintenance. Payments for the transfer of goods or services such as common area maintenance and utilities represent non-lease components. The Company elected the package of practical expedients and therefore does not separate non-lease components from lease components.

Certain agreements call for payments that are based on historical compensation, and accordingly, the amount of the contractual commitment will change over time commensurate with the executive’s applicable earnings. At December 31, 2020, future commitments for such key executives were approximately $20.1 million. In certain circumstances, the agreements call for the acceleration of equity vesting.

Stock-Based Compensation | 9. Stock-Based Compensation Common Stock There were 150,000,000 and 120,000,000 shares of common stock authorized at December 31, 2020 and 2019, respectively. Preferred Stock There are 5,000,000 shares of preferred stock authorized and none issued or outstanding at December 31, 2020 and 2019. Stock-based Compensation In March 2014, the Compensation Committee (the "Compensation Committee") of the Board of Directors of the Company adopted the 2014 Equity Incentive Plan of NuVasive, Inc. (the "2014 EIP"), replacing the 2004 Amended and Restated Equity Incentive Plan (the “2004 EIP”). No further awards may be granted under the 2004 EIP; however, that plan continues to govern all awards previously issued under it (of which awards remain outstanding). The 2014 EIP provides the Company with the ability to grant various types of equity awards to its workforce (including, without limitation, restricted stock units (“RSUs”), restricted stock awards, performance awards, and deferred stock awards). The 2014 EIP also provides for the issuance of performance RSUs (“PRSUs”) to be granted subject to time- and/or performance-based vesting requirements. In addition, the award agreements under the 2014 EIP generally provide for the acceleration of 50% of the unvested equity awards of all employees upon a change in control and the vesting of the remaining unvested equity awards for those employees that are involuntarily terminated within a year of the change in control. Each of the 2004 EIP and the 2014 EIP allow for “net share settlement” of certain equity awards whereby, in lieu of (i) making cash payments in satisfaction of the exercise price owed respective to non-qualified stock option awards, or (ii) open market selling award shares to generate cash proceeds for use in satisfaction of statutory tax obligations respective to an award’s settlement or exercise, the company offsets the award shares being settled in a respective transaction by the number of shares of company stock with a value equal to the respective obligation, and, in the case of taxes, making a cash payment to the respective taxing authority on behalf of the employee using Company cash. The net share settlement is accounted for with the cost of any award shares that are net settled being included in treasury stock and reported as a reduction in total equity at the time of settlement. In connection with the acquisition of Ellipse Technologies in February 2016, the Company assumed the Ellipse Technologies, Inc. 2015 Incentive Award Plan and the shares thereunder, subject to an equity exchange adjustment, for future awards by the Company. The compensation cost that has been included in the Consolidated Statements of Operations for the Company’s stock-based compensation plans was as follows: Year Ended December 31, ( in thousands 2020 2019 2018 Selling, general and administrative expense $ 12,622 $ 25,968 $ 22,190 Research and development expense 5,259 3,798 3,052 Cost of sales 264 531 431 Stock-based compensation expense before taxes 18,145 30,297 25,673 Related income tax benefits (3,088 ) (6,191 ) (6,418 ) Stock-based compensation expense, net of taxes $ 15,057 $ 24,106 $ 19,255 As of December 31, 2020, there was $21.0 million and $16.1 million of unrecognized compensation expense for RSUs and PRSUs, respectively, which is expected to be recognized over a weighted-average period of approximately 1.7 years and 2.7 years, respectively. In addition, as of December 31, 2020, there was $1.0 million of unrecognized compensation expense for shares expected to be issued under the ESPP which is expected to be recognized through April 2021. There was no unamortized expense for stock options as of December 31, 2020. Restricted Stock Units The total fair value of RSUs that vested during the year ended December 31, 2020, 2019, and 2018 was $12.1 million, $21.5 million and $8.8 million, respectively.

The total shares withheld related to vested RSUs were approximately 71,000, 122,000, and 42,000 in 2020 2019 , and 2018 , respectively, and were based on the value of the awards on their vesting dates as determined by the Company’s closing stock price. Total payments for the employees’ tax obligations to the taxing authorities related to vesting RSUs were $4.1 million, $7.2 million and $2.2 million in 2020 , 2019 and 2018 , respectively. Performance-Based Restricted Stock Units The Company has granted PRSUs since 2012 for which the ultimate issuance amount is determined by the Company’s Compensation Committee upon its certification of Company performance against a pre-determined matrix, which have included targets for net sales, operating margin, earnings per share and total shareholder return over pre-determined periods of time. Share payout levels range from 0% to 200% depending on the respective terms of an award. Based upon the Company’s actual performance against the performance conditions, approximately 61,000, 276,000 and 21,000 shares of common stock vested pursuant to PRSUs in 2020, 2019 and 2018, respectively. In 2015, the Company granted a PRSU award with a five-year subject to recurring fair value adjustments that affect stock-based compensation expense. The total fair value of PRSUs vested during 2020, 2019, 2018 and was $3.8 million, $19.9 million and $2.1 million, respectively.

The total shares withheld related to vesting PRSUs were approximately 25,000, 121,000 and 8,000 in 2020 2019 and 2018 respectively, and were based on the value of the awards on their vesting dates as determined by the Company’s closing stock price. Total payments for the employees’ tax obligations to the taxing authorities related to vesting PRSUs were $1.6 million, $7.2 million, and $0.4 million in 2020 2019 , and 2018 respectively. Stock Options The Company has not granted any stock options since 2011. The stock options previously granted are exercisable for a period of up to ten years after the date of grant. The aggregate intrinsic value of outstanding stock options at December 31, 2020 is based on the Company’s closing stock price on December 31, 2020 of $56.33. Stock option exercises during the years ended December 31, 2020 and 2019 were primarily all executed with net share settlements, for which the Company does not receive any cash proceeds. The Company received $1.3 million in proceeds from the exercise of stock options during the year ended December 31, 2018. The total intrinsic value of stock options exercised was $0.4 million, $1.0 million, and $2.5 million during the years ended December 31, 2020, 2019 and 2018, respectively. There were no stock options that vested during the years ended December 31, 2020, 2019 or 2018.

Since income taxes for these subsidiaries are assessed in their local currency, deferred tax balances are translated into the Company’s reporting currency and adjusted for changes in the exchange rates over time through the cumulative translation account. Additionally, the Company established certain deferred taxes associated with the issuance of convertible debt in 2020 the benefit of which was recorded to equity. Accordingly, changes in the deferred tax balances associated with revaluations and convertible debt issuances are not reflected in income tax expense and create disparities between the changes in total deferred taxes for the year and deferred tax expense. In the year ended December 31, 2020, net decreases in deferred taxes of approximately $0.8 million and decreases in valuation allowances of approximately $1.3 million were recorded against equity and, therefore, not reflected in deferred tax expense. The following table summarizes the activity related to the Company’s unrecognized tax benefits: Year Ended December 31, ( in thousands 2020 2019 2018 Gross unrecognized tax benefits at January 1 $ 20,328 $ 19,545 $ 25,356 Increases in tax positions for prior years 1,758 62 499 Decreases in tax positions for prior years — (112 ) (756 ) Increases in tax positions for current year relating to ongoing operations 2,159 2,073 1,913 Decreases in tax positions as a result of a lapse of statute of limitations (5,929 ) (616 ) (6,446 ) Increases in tax positions for current year relating to acquisitions — — 169 Decreases in tax positions due to settlements with taxing authorities — (624 ) (1,190 ) Gross unrecognized tax benefits at December 31 $ 18,316 $ 20,328 $ 19,545 At December 31, 2020, 2019, and 2018, $16.5 million, $18.7 million, and $18.1 million, respectively, of the Company’s total unrecognized tax benefits, if recognized, would impact the effective income tax rate. In accordance with the disclosure requirements as described in ASC Topic 740, Income Taxes, the Company classified uncertain tax positions as non-current income tax liabilities unless expected to be paid in one year. The Company’s continuing practice is to recognize interest and/or penalties related to income tax matters in income tax expense. For the years ended December 31, 2020, 2019, and 2018, the Company recognized approximately $(0.1) million, $0.1 million, and $(0.5) million, respectively, in interest and penalties as income tax (benefit) expense in the Consolidated Statements of Operations. The Company had approximately $0.1 million for the payment of interest and penalties accrued at both December 31, 2020 and 2019 in the Consolidated Balance Sheets. The Company believes it is reasonably possible that approximately $2.4 million of its remaining unrecognized tax positions, primarily attributable to withholding obligations and the valuation of intercompany transactions, may decrease by the end of 2021 as we reach settlements with taxing authorities or certain statute of limitations expire. In November 2018, the Company completed a reorganization of its international intellectual property company structure. This international restructuring generated a step-up in local tax basis, which under ASC Topic 740-10-25-20 ASU 2016-16, The Company is subject to routine compliance reviews on various tax matters around the world in the ordinary course of business. Currently, the only active audit is with the U.S. Internal Revenue Service for 2014 – 2016 tax years. California is subject to examination in all years due to prior year net operating losses and research and development credits. Other major state and foreign jurisdictions remain subject to examination from 2016 and 2013 forward, respectively. The Company made the accounting policy election to treat taxes due on U.S. inclusions in taxable income related to Global Intangible Low-Taxed Income as a current period expense when incurred (the "period cost method"). The Company has approximately $13.2 million of undistributed earnings attributable to operations in its controlled foreign corporations as of December 31, 2020. Due to recent tax reform in the United States and favorable treaties between the United States and countries in which its controlled foreign corporations operate, the Company has the ability to repatriate earnings without incurring additional tax liabilities. Accordingly, the Company has not recorded a liability for taxes associated with any future distributions of these undistributed earnings. At December 31, 2020, the Company had $2.0 million, $50.9 million and $0.1 million of federal, state and foreign net operating loss carryforwards, respectively. Federal net operating loss carryforwards begin to expire in 2026, state net operating loss carryforwards begin to expire in 2021, and foreign net operating losses carry forward indefinitely. The Company also has federal and California research and development income tax credit carryforwards of $11.4 million and $35.7 million, respectively. The federal credits will begin to expire in 2038, while the California credits can be carried forward indefinitely. Due to the “change of ownership” provision of the Tax Reform Act of 1986, utilization of the Company’s net operating loss and credit carryforwards may be subject to an annual limitation against taxable income in future periods. As a result of any future ownership changes, the annual limitation of loss and credit carryforwards may cause them to expire before ultimately becoming available to reduce future income tax liabilities. |

Business Segment, Product and Geographic Information | 11. Business Segment, Product and Geographic Information The Company operates in one The Company’s CODM reviews net sales at the product line offering level, and manufacturing, operating income and expenses, and net income at the Company-wide level to allocate resources and assess the Company’s overall performance. The Company shares common, centralized support functions, including finance, human resources, legal, information technology, and corporate marketing, all of which report directly to the CODM. Accordingly, decision-making regarding the Company’s overall operating performance and allocation of Company resources is assessed on a consolidated basis. The Company has disclosed the net sales for each of its product line offerings to provide the reader of the financial statements transparency into the operations of the Company. The Company reports under two distinct product lines; spinal hardware and surgical support. The Company’s spinal hardware product line offerings include implants and fixation products. The Company’s surgical support product offerings include IONM services, disposables and biologics, and our capital equipment, all of which are used to aid spinal surgery.

Contingencies [Abstract] | |
Contingencies | 12. Contingencies The Company is subject to potential liabilities under government regulations and various claims and legal actions that are pending or may be asserted from time-to-time. These matters arise in the ordinary course and conduct of the Company’s business and include, for example, commercial, intellectual property, environmental, securities and employment matters. The Company intends to continue to defend itself vigorously in such matters and when warranted, take legal action against others. Furthermore, the Company regularly assesses contingencies to determine the degree of probability and range of possible loss for potential accrual in its financial statements. During the year ended December 31, 2018 An estimated loss contingency is accrued in the Company’s financial statements if it is probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Based on the Company’s assessment, it has adequately accrued an amount for contingent liabilities currently in existence. The Company does not accrue amounts for liabilities that it does not believe are probable. Litigation is inherently unpredictable, and unfavorable resolutions could occur. As a result, assessing contingencies is highly subjective and requires judgment about future events. The amount of ultimate loss may exceed the Company’s current accruals, and it is possible that its cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies. |

(the “Company” or “NuVasive”) was incorporated in Delaware on July 21, 1997, and began commercializing its products in 2001. • • • • • The Company has also invested in enabling technologies, including the development of capital equipment designed to further improve clinical, financial, and operational outcomes of spine surgery. The Company’s capital equipment portfolio currently consists of Lessray and the Pulse platform. Lessray is an image enhancement platform designed to reduce radiation exposure in the operating room by allowing surgeons to take low-quality, low-dose images and improve them to look like conventional full-dose images. Pulse integrates multiple enabling technologies within a single, expandable platform and is engineered to improve workflow, reduce variability, and increase the reproducibility of surgical outcomes. The Pulse platform’s modular architecture is designed to incorporate applications for neuromonitoring Selling and leasing of capital equipment do not make up a material portion of the Company’s total net sales. In addition to the Company’s procedurally integrated solutions for spine surgery, it also designs and sells expandable growing rod implant systems that can be non-invasively lengthened following implantation with precise, incremental adjustments via an external remote controller using magnetic technology called MAGnetic External Control (“MAGEC”), which allows for the minimally invasive treatment of early-onset and adolescent scoliosis. This technology is also the basis for the Company’s Precice limb lengthening system, which allows for the correction of long bone limb length discrepancy, as well as other products for treating specialized orthopedic procedures. In December 2019, a novel strain of coronavirus, which causes COVID-19, was identified. Due to the rapid and global spread of the virus, on March 11, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. To slow the proliferation of COVID-19, governments have implemented extraordinary measures, which include the mandatory closure of businesses, restrictions on travel and gatherings, and quarantine and physical distancing requirements. In addition, many government agencies in conjunction with hospitals and healthcare systems have, to varying degrees, deferred or suspended elective surgical procedures. While certain spine surgeries are deemed essential and certain surgeries, like in cases of trauma, cannot be delayed, the Company has seen and may continue to see a significant reduction in procedural volumes as hospital systems and/or patients elect to defer spine surgery procedures. As a result of these measures, the Company has experienced reductions in procedural volumes during 2020 and anticipates this trend may continue. |
Basis of Presentation and Principles of Consolidation | Basis of Presentation and Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of the Company and its majority-owned or controlled subsidiaries, collectively referred to as either NuVasive or the Company. The Company translates the financial statements of its foreign subsidiaries using end-of-period exchange rates for assets and liabilities and average exchange rates during each reporting period for results of operations. When there is a portion of equity in an acquired subsidiary not attributable, directly or indirectly, to the respective parent entity, the Company records the fair value of the non-controlling interest at the acquisition date and classifies the amounts attributable to non-controlling interest separately in equity in the Company's Consolidated Financial Statements. Any subsequent changes in a parent's ownership interest while the parent retains its controlling financial interest in its subsidiary are accounted for as equity transactions. All significant intercompany balances and transactions have been eliminated in consolidation. The Company has replaced the caption “Revenue” with “Net sales,” and the caption “Sales, marketing and administrative” with “Selling, general and administrative,” within the Consolidated Statements of Operations and corresponding changes have been made throughout this Annual Report to conform to this presentation. These updated captions have no impact on previously reported results of operations or financial position. |
Use of Estimates | Use of Estimates To prepare financial statements in conformity with generally accepted accounting principles (“GAAP”) accepted in the United States, management must make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. |
Recently Accounting Pronouncements Not Yet Adopted And Recently Adopted Accounting Standards | Recent Accounting Pronouncements Not Yet Adopted In January 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2020-01, Investments—Equity Securities (Topic 321), Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815)—Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (a consensus of the Emerging Issues Task Force) The Company will adopt ASU 2020-01 on January 1, 2021, and does not expect a material impact to its Consolidated Financial Statements. In August 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40) 115.4 Recently Adopted Accounting Standards In June 2016, the FASB issued Accounting Standards Update No. 2016-13, Financial Instruments – Credit Losses (“ASU 2016-13”), which changes the accounting for recognizing impairments of financial assets. Under the new guidance, credit losses for certain types of financial instruments will be estimated based on expected losses. The new guidance also modifies the impairment models for available-for-sale debt securities and for purchased financial assets with credit deterioration since their origination. January 1, 2020 In January 2017, the FASB issued Accounting Standards Update No. 2017-04, Intangibles – Goodwill and Other In August 2018, the FASB issued Accounting Standards Update No. 2018-13, Fair Value Measurement: Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement In September 2018, the FASB issued Accounting Standards Update No. 2018-15, Intangible – Goodwill and Other – Internal-Use Software In December 2019, the FASB issued Accounting Standards Update No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which modifies Accounting Standard Codification 740 – Income Taxes (“ASC 740”). ASU 2019-12 enhances and simplifies various aspects of the income tax accounting guidance in ASC 740. This update is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years, and early adoption is permitted. The Company elected to early adopt ASU 2019-12 in the quarter ended June 30, 2020. The Company applied the updated guidance for year-to-date losses in the Company’s interim period tax accounting on a prospective basis. The early adoption had no impact on the expected full year tax expense for 2020, but rather accelerated certain tax benefits to earlier quarters in 2020 that would otherwise have been limited under ASC 740. In March 2020, the FASB issued Accounting Standards Update No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting |
Revenue Recognition | Revenue Recognition In accordance with Accounting Standards Codification 606 Revenue from Contracts with Customers (“ASC 606”), the Company recognizes revenue upon the transfer of goods or services to a customer at an amount that reflects the expected consideration to be received in exchange for those goods or services. The principles in ASC 606 are applied using the following five steps: (i) identify the contract with a customer; (ii) identify the performance obligation(s) in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligation(s) in the contract; and (v) recognize revenue when (or as) the Company satisfies its performance obligation(s). Specifically, revenue from the sale of implants, fixation products and disposables is generally recognized at an amount that reflects the expected consideration upon notice that the Company’s products have been used in a surgical procedure or upon shipment to a third-party customer assuming control of the products. Revenue from IONM services is recognized in the period the service is performed for the amount of consideration expected to be received. Revenue from the sale of surgical instrument sets is generally recognized upon receipt of a purchase order and the subsequent shipment to a customer who assumes control. In certain cases, the Company does offer the ability for customers to lease surgical instrumentation primarily on a non-sales type basis. Revenue from the sale or lease of is recognized when the Company transfers control to the customer, which is generally at the point when acceptance occurs that indicates customer acknowledgment of delivery or installation, depending on the terms of the arrangement |
Accounts Receivable and Related Valuation Accounts | Accounts Receivable and Related Valuation Accounts Accounts receivable in the accompanying Consolidated Balance Sheets are presented net of allowances for credit losses. The Company maintains an allowance for credit losses resulting from the inability of its customers, including hospitals, ambulatory surgery centers, and distributors, to make required payments. The allowance for credit losses is calculated quarterly, and is estimated on a region-by-region basis considering a number of factors including age of account balances, collection history, historical account write-offs, third party credit reports, identified trends, current economic conditions, and supportable forecasted economic expectations. The allowance is adjusted on a specific identification basis for certain accounts as well as pooling of accounts with similar characteristics. An increase in the provision for credit losses may be required when the financial condition of the Company’s customers or its collection experience deteriorates. An increase to the allowance for credit losses results in a corresponding charge to selling, general and administrative expenses. The Company has a diverse customer base and no single customer represented greater than ten percent of net sales or accounts receivable. Historically, the Company’s reserves have been adequate to cover credit losses. The Company's exposure to credit losses may increase if its customers are adversely affected by changes in healthcare laws, coverage and reimbursement, economic pressures or uncertainty associated with local or global economic recessions, disruption associated with the current COVID-19 pandemic, or other customer-specific factors. It is possible that there could be a material adverse impact from potential adjustments of the carrying amount of trade receivables as customers’ cash flows are impacted by their response to the COVID-19 pandemic and the deferral of elective surgical procedures. The following table summarizes the changes in the allowance for credit losses: (in thousands) December 31, 2020 Allowance for credit losses at January 1, 2020 $ 9,423 Current-period provision for expected losses 1,079 Write-offs charged against the allowance (1,305 ) Recoveries of amounts previously written off 220 Changes resulting from foreign currency fluctuations 229 Allowance for credit losses at end of period $ 9,646 In addition, the Company establishes a liability for estimated sales returns and a reserve for price adjustments that are recorded as a reduction to net sales. The liability and reserve are maintained to account for the future product returns and price adjustments of products sold in the current period. |
Concentration of Credit Risk and Significant Customers | Concentration of Credit Risk and Significant Customers Financial instruments, which potentially subject the Company to concentrations of credit risk, consist primarily of cash and cash equivalents, marketable securities and accounts receivable. The Company limits its exposure to credit loss by placing its cash and investments with high credit quality financial institutions. Additionally, the Company has established guidelines regarding diversification of its investments and their maturities, which are designed to maintain principal and maximize liquidity. The Company has a diverse customer base and no single customer represented greater than ten percent of sales or accounts receivable for any of the periods presented. |
Fair Value of Financial Instruments | Fair Value of Financial Instruments The Company’s financial instruments consist principally of cash and cash equivalents, marketable securities, restricted investments, derivatives, contingent consideration liabilities, accounts receivable, accounts payable, accrued expenses, and Senior Convertible Notes. The Company measures certain assets and liabilities in accordance with authoritative guidance which requires fair value measurements to be classified and disclosed in one of the following three categories: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. Level 2: Observable prices that are based on inputs not quoted on active markets, but corroborated by market data. Level 3: Unobservable inputs are used when little or no market data is available. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value measurement hierarchy during the years presented. |
Cash and Cash Equivalents | Cash and Cash Equivalents The Company considers all highly liquid investments that are readily convertible into cash and have an original maturity of three months or less at the time of purchase to be cash equivalents. |
Inventory, net | Inventory, net Net inventory as of December 31, 2020 consisted of $285.4 million of finished goods, $7.3 million of work in progress and $7.9 million of raw materials. Net inventory as of December 31, 2019 consisted of $298.7 million of finished goods, $6.4 million of work in progress and $7.3 million of raw materials. Finished goods primarily consists of specialized implants, fixation products and disposables and are stated at the lower of cost or net realizable value determined by utilizing a standard cost method, which includes capitalized variances, which approximates the weighted average cost. Work in progress and raw materials represent the underlying material, and labor for work in progress, that ultimately yield finished goods upon completion and are subject to lower of cost or net realizable value. The Company reviews the components of its inventory on a periodic basis for excess and obsolescence and adjusts inventory to its net realizable value as necessary. The Company records an inventory reserve for estimated excess and obsolete inventory based upon historical turnover and assumptions about future demand for its products and market conditions, such as product life cycles and timing of the introduction and development of new or enhanced products One of the Company’s strategic objectives is to continue to rapidly develop and commercialize new products and product enhancements For the year ended December 31, 2020 and 2019, the Company recorded a reserve for excess and obsolete inventory of $48.9 million and $14.0 million, respectively. The increase is primarily attributable to updates to the Company’s estimates and assumptions about future product demand and product life cycles which have been affected by multiple factors, including the COVID-19 pandemic and general market conditions |
Goodwill and Intangible Assets | Goodwill and Intangible Assets The Company’s goodwill represents the excess of the cost over the fair value of net assets acquired from its business combinations. The determination of the value of goodwill and intangible assets arising from business combinations and asset acquisitions requires extensive use of accounting estimates and judgments to allocate the purchase price to the fair value of the net tangible and intangible assets acquired, including capitalized Intangible assets acquired in a business combination that are used for in-process research and development activities are considered indefinite lived until the completion or abandonment of the associated research and development efforts. Upon reaching the end of the relevant research and development project, the Company will amortize the acquired IPR&D over its estimated useful life or expense the acquired in-process research and development should the research and development project be unsuccessful with no future alternative use. Goodwill and IPR&D are not amortized; however, they are assessed for impairment using fair value measurement techniques on an annual basis or more frequently if facts and circumstance warrant such a review. The goodwill or IPR&D are considered to be impaired if the Company determines that the carrying value of the reporting unit or IPR&D exceeds its respective fair value. The Company performs its goodwill impairment analysis at the reporting unit level, which aligns with the Company’s reporting structure and availability of discrete financial information. The Company performs its annual impairment analysis by either comparing a reporting unit’s estimated fair value to its carrying amount or doing a qualitative assessment of a reporting unit’s fair value from the last quantitative assessment to determine if there is potential impairment. The Company may do a qualitative assessment when the results of the previous quantitative test indicated the reporting unit’s estimated fair value was significantly in excess of the carrying value of its net assets and it does not believe there have been significant changes in the reporting unit’s operations that would significantly decrease its estimated fair value or significantly increase its net assets. If a quantitative assessment is performed the evaluation includes management estimates of cash flow projections based on internal future projections and/or use of a market approach by looking at market values of comparable companies . Key assumptions for these projections include net sales growth, future gross and operating margin growth, and its weighted cost of capital and terminal growth rates. The net sales and margin growth is based on increased sales of new and existing products as the Company maintains investments in research and development. Additional assumed value creators may include increased efficiencies from capital spending. The resulting cash flows are discounted using a weighted average cost of capital. Operating mechanisms and requirements to ensure that growth and efficiency assumptions will ultimately be realized are also considered in the evaluation, including timing and probability of regulatory approvals for Company products to be commercialized. The Company’s market capitalization is also considered as a part of its analysis. The Company’s annual evaluation for impairment of goodwill consists of one reporting unit. In accordance with the Company’s policy, the Company completed its most recent annual evaluation for impairment as of October 1, 2020 using the qualitative assessment and determined that no impairment existed. In addition, no indicators of impairments were noted through and consequently, no impairment charge has been recorded during the year. Intangible assets with a finite life, such as acquired technology, customer relationships, manufacturing know-how, licensed technology, supply agreements and certain trade names and trademarks, are amortized on a straight-line basis over their estimated useful life, ranging from 2 to 17 years. In determining the useful lives of intangible assets, the Company considers the expected use of the assets and the effects of obsolescence, demand, competition, anticipated technological advances, changes in surgical techniques, market influences and other economic factors. For technology based intangible assets, the Company considers the expected life cycles of products which incorporate the corresponding technology. Trademarks and trade names that are related to products are assigned lives consistent with the period in which the products bearing each brand are expected to be sold. The Company evaluates its intangible assets with finite lives for indications of impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Factors that could trigger an impairment review include significant under-performance relative to expected historical or projected future operating results, significant changes in the manner of the Company’s use of the acquired assets or the strategy for the Company’s overall business or significant negative industry or economic trends. If this evaluation indicates that the value of the intangible asset may be impaired, the Company makes an assessment of the recoverability of the net carrying value of the asset over its remaining useful life. If this assessment indicates that the intangible asset is not recoverable, based on the estimated undiscounted future cash flows of the technology over the remaining amortization period, the Company reduces the net carrying value of the related intangible asset to fair value and may adjust the remaining amortization period. See Note 2 to the Consolidated Financial Statements included in this Annual Report for further disclosure on goodwill and intangible assets. |
Property and Equipment | Property and Equipment Property and equipment are carried at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, ranging from 2 to 20 years. The Company depreciates leasehold improvements over their estimated useful lives or the term of the applicable lease, whichever is shorter. Leased property meeting certain financing lease criteria is capitalized under property and equipment, and the net present value of the related lease payments is recorded as a liability. Amortization of assets under financing leases is recorded using the straight-line method over the shorter of the estimated useful lives or the lease terms. The Company reviews property, plant and equipment for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. An impairment loss would be recognized when estimated future undiscounted cash flows relating to the asset are less than its carrying amount. An impairment loss is measured as the amount by which the carrying amount of an asset exceeds its fair value. |
Income Taxes | Income Taxes The asset and liability approach is used to recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax bases of assets and liabilities. Tax law and rate changes are reflected in income in the period such changes are enacted. The Company includes interest and penalties related to income taxes, including unrecognized tax benefits, within income tax expense. The Company’s income tax returns are based on calculations and assumptions that are subject to examination by the Internal Revenue Service and other tax authorities. In addition, the calculation of the Company’s tax liabilities involves dealing with uncertainties in the application of comp lex tax regulations. The Company recognize s liabilities for uncertain tax positions based on a two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon settlement. While the Company believe s it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of examinations by tax authorities in determining the adequacy of its provision for income taxes. The Company continually assess es the likelihood and amount of potential revisions and adjusts the income tax provision, income taxes payable and deferred taxes in the period in which the facts that give rise to a revision become known. Significant judgment is required in determining the Company’s provision for income taxes, deferred tax assets and liabilities and the valuation allowance recorded against net deferred tax assets. Deferred tax assets and liabilities are determined using the enacted tax rates in effect for the years in which those tax assets are expected to be realized. A valuation allowance is established when it is more likely than not the future realization of all or some of the deferred tax assets will not be achieved. The evaluation of the need for a valuation allowance is performed on a jurisdiction-by-jurisdiction basis, and includes a review of all available positive and negative evidence. Factors reviewed include projections of pre-tax book income for the foreseeable future, determination of cumulative pre-tax book income after permanent differences, earnings history, and reliability of forecasting. Based on the Company’s review, it concluded that it was more likely than not that it would be able to realize the future benefits of its domestic and foreign deferred tax assets, with the exceptions of California, Malta, Mexico, Brazil and Colombia. This conclusion was based on historical and projected operating performance, as well as the Company’s expectation that its operations will generate sufficient taxable income in future periods to realize the tax benefits associated with the deferred tax assets well within the statutory carryover periods. Due to low state apportionment, large net operating losses and the generation of sizeable research credits in California, the Company concluded that it is not more likely than not that it will be able to utilize its California deferred tax assets. Therefore, the Company has maintained a full valuation allowance on its California deferred tax assets as of December 31, 2020. Due to a history of losses in Malta, Brazil, Mexico and Colombia, and the lack of alternative sources of future taxable income, the Company has established a full valuation allowance against these entities’ deferred tax assets as of December 31, 2020. The Company will continue to assess the need for a valuation allowance on its deferred tax assets by evaluating both positive and negative evidence that may exist. Any adjustment to the net deferred tax asset valuation allowance would be recorded in the statement of operations for the period that the adjustment is determined to be required. See Note 10 to the Consolidated Financial Statements included in this Annual Report for further discussion on income taxes. |
Loss Contingencies | Loss Contingencies An estimated loss contingency is accrued and disclosed in the Company’s financial statements if it is probable or disclosed if it is reasonably possible that a liability has been incurred and the amount of the loss can be reasonably estimated. Based on the Company’s assessment, it has adequately accrued an amount for contingent liabilities currently in existence. The Company does not accrue amounts for liabilities that it does not believe are probable and only discloses those matters it considers material to its overall financial position. In most cases, significant judgment is required to estimate the amount and timing of a loss to be recorded. The Company is involved in a number of legal actions arising in the normal course of business. The outcomes of these legal actions are not within the Company’s complete control and may not be known for prolonged periods of time. In some actions, the claimants seek damages as well as other relief, including injunctions barring the sale of products that are the subject of the lawsuit, that could require significant expenditures or result in lost net sales. Litigation is inherently unpredictable, and unfavorable resolutions could occur. As a result, assessing contingencies is highly subjective and requires judgment about future events. The amount of ultimate loss may exceed the Company’s current accruals, and it is possible that its cash flows or results of operations could be materially affected in any particular period by the unfavorable resolution of one or more of these contingencies. See Note 12 to the Consolidated Financial Statements included in this Annual Report for further discussion on legal proceedings and investigations. |
Comprehensive Income | Comprehensive Income Comprehensive income is defined as the change in equity during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income includes net of tax, unrealized gains or losses on the Company’s marketable debt securities and foreign currency translation adjustments. The cumulative translation adjustments included in accumulated other comprehensive loss were $7.6 million, $9.4 million, and $8.6 million at December 31, 2020, 2019, and 2018, respectively. |
Research and Development | Research and Development Research and development costs are expensed as incurred. To the extent the Company purchases research and development assets with a future alternative use the Company will capitalize and amortize the assets over its useful life. |
Product Shipment Costs | Product Shipment Costs Product shipment costs, included in selling, general and administrative expense in the accompanying Consolidated Statements of Operations, were $27.4 million, $27.7 million, and $25.4 million for the years ended December 31, 2020, 2019, and 2018, respectively. The majority of the Company’s shipping costs are associated with providing instrument sets to hospitals for use in individual surgical procedures. Amounts billed to customers for shipping and handling of products are reflected in net sales and are not material for any period presented. |
Business Transition Costs | Business Transition Costs The Company incurs certain costs related to acquisition, integration and business transition activities, which include severance, relocation, consulting, leasehold exit costs, third-party merger and acquisition costs, contingent consideration fair value adjustments and other costs directly associated with such activities. Contingent consideration is accrued based on the fair value of the expected payment, and such accruals are subject to increase or decrease based on the assessment of the likelihood that the contingent milestones will be achieved resulting in payment. If an accrual for contingent consideration decreases during a particular period, it results in a reduction of costs during such period. During the year ended December 31, 2020, the Company recorded $10.9 million of costs related to acquisition, integration and business transition activities, which included $2.3 million of fair value adjustments on contingent consideration liabilities associated with the Company’s 2018, 2017 and 2016 acquisitions. During the year ended December 31, 2019, the Company recorded a reduction of costs of $(2.0) million related to acquisition, integration and business transition activities, which included $(6.3) million of fair value adjustments on contingent consideration liabilities associated with the Company’s 2018, 2017 and 2016 acquisitions. During the year ended December 31, 2018, the Company recorded $11.5 million of costs related to acquisition, integration and business transition activities, which included $(1.5) million of fair value adjustments on contingent consideration liabilities associated with the Company’s 2018, 2017 and 2016 acquisitions. |
Stock-based Compensation | Stock-based Compensation Stock-based compensation expense for equity-classified awards, principally related to restricted stock units (“RSUs”) and performance restricted stock units (“PRSUs”), is measured at the grant date based on the estimated fair value of the award. The fair value of equity instruments that are expected to vest is recognized and amortized over the requisite service period. The Company has granted awards with up to five year graded or cliff vesting terms . The fair value of RSUs including PRSUs with pre-defined performance criteria pre-defined performance criteria is adjusted with the probability of achievement of such performance criteria at each period end Stock-based compensation expense is adjusted from the grant date to exclude expense for awards that are expected to be forfeited. The forfeiture estimate is adjusted as necessary through the vesting date so that full compensation cost is recognized only for awards that vest. The Company assesses the reasonableness of the estimated forfeiture rate at least annually, with any change to be made on a cumulative basis in the period the estimated forfeiture rates change. The Company considered its historical experience of pre-vesting forfeitures on awards by each homogenous group of employees as the basis to arrive at its estimated annual pre-vesting forfeiture rates. The Company estimates the fair value of stock options issued under its equity incentive plans and shares issued to employees under its employee stock purchase plan (“ESPP”) using a Black-Scholes option-pricing model on the date of grant. The Black-Scholes option-pricing model incorporates various assumptions including expected volatility, expected term and risk-free interest rates. The expected volatility is based on the historical volatility of the Company’s common stock over the most recent period commensurate with the estimated expected term of the Company’s stock options and ESPP offering period which is derived from historical experience. The risk-free interest rate for periods within the contractual life of the option is based on the U.S. Treasury yield in effect at the time of grant. The Company has never declared or paid dividends and has no plans to do so in the foreseeable future . See Note 9 to the Consolidated Financial Statements included in this Annual Report for further discussion on stock-based compensation. |
Net Income Per Share | Net (Loss) Income Per Share The Company computes basic net income per share using the weighted-average number of common shares outstanding during the period. Diluted net income per share assumes the conversion, exercise or issuance of all potential common stock equivalents, unless the effect of inclusion would be anti-dilutive. For purposes of this calculation, common stock equivalents include the Company’s stock options, unvested RSUs, PRSUs (including those with performance and market conditions), warrants, and the shares to be issued upon the conversion of the Senior Convertible Notes. The contingently issuable shares are included in basic net income per share as of the date that all necessary conditions have been satisfied and are included in the denominator for dilutive calculation for the entire period if such shares would be issuable as of the end of the reporting period assuming the end of the reporting period was the end of the contingency period. The following table sets forth the computation of basic and diluted consolidated net (loss) income per share: Year Ended December 31, ( in thousands, except per share data 2020 2019 2018 Numerator: Net (loss) income $ (37,153 ) $ 65,234 $ 12,479 Denominator for basic and diluted net (loss) income per share: Weighted average common shares outstanding for basic 51,416 51,956 51,382 Dilutive potential common stock outstanding: Stock options and ESPP — 15 36 RSUs and PRSUs — 658 760 Senior Convertible Notes — 531 177 Weighted average common shares outstanding for diluted 51,416 53,160 52,355 Basic net (loss) income per share $ (0.72 ) $ 1.26 $ 0.24 Diluted net (loss) income per share $ (0.72 ) $ 1.23 $ 0.24 The following weighted outstanding common stock equivalents were not included in the calculation of net (loss) income per diluted share because their effects were anti-dilutive: Year Ended December 31, ( in thousands 2020 2019 2018 Stock options, ESPP, RSUs and PRSUs 1,095 115 162 Warrants 21,034 10,865 10,865 Senior Convertible Notes 21,034 5,433 5,433 Total 43,163 16,413 16,460 |
