NuVasive, Inc.
Notes to Unaudited Condensed Consolidated Financial Statements
1. Description of Business and Basis of Presentation
Description of Business
     NuVasive®, Inc. (the Company or NuVasive) was incorporated in Delaware on July 21, 1997. The Company is focused on developing minimally disruptive surgical products and procedures for the spine. The Company began commercializing its products in 2001. Its currently-marketed product portfolio is focused on applications for spine fusion surgery. Its principal product offering includes a minimally disruptive surgical platform called Maximum Access Surgery, or MAS®, as well as a growing offering of biologics, cervical and motion preservation products. In the spine surgery market, the Company’s currently-marketed products are primarily used to enable access to the spine and to perform restorative and fusion procedures in a minimally disruptive fashion. The Company also focuses significant research and development efforts on expanding its MAS product platform, advancing the applications of their unique technology to additional procedures, and developing motion preservation products. The Company dedicates significant resources toward training spine surgeons on its unique technology and products.
     The Company’s primary business model is to loan its MAS systems to surgeons and hospitals who purchase disposables and implants for use in individual procedures. In addition, for larger customers, the Company’s proprietary nerve monitoring systems, MaXcess® and surgical instrument sets are placed with hospitals for an extended period at no up-front cost to them. The Company also offers a range of bone allograft in patented saline packaging, disposables and spine implants, which include its branded CoRoent® products and fixation devices such as rods, plates and screws. Implants and disposables are shipped from the Company’s inventories. The Company sells an immaterial quantity of MAS instrument sets, MaXcess and nerve monitoring systems to hospitals.
Basis of Presentation
     The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Pursuant to these rules and regulations, the Company has condensed or omitted certain information and footnote disclosures it normally includes in its annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP). In the opinion of management, the consolidated financial statements include all adjustments necessary, which are of a normal and recurring nature, for the fair presentation of the Company’s financial position and of the results of operations and cash flows for the periods presented.
     The accompanying unaudited condensed consolidated financial statements as of December 31, 2010 and for the three and six months ended June 30, 2011 and 2010 include the accounts of the Company and its wholly owned subsidiaries, as well as the accounts of a variable interest entity, Progentix Orthobiology, B.V. (Progentix), which is consolidated pursuant to existing guidance issued by the Financial Accounting Standards Board (FASB). All significant intercompany accounts and transactions have been eliminated in consolidation.
     These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2010 included in NuVasive’s Annual Report on Form 10-K filed with the SEC. Operating results for the three and six months ended June 30, 2011 are not necessarily indicative of the results that may be expected for any other interim period or for the full year. The balance sheet at December 31, 2010 has been derived from the audited financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements.
Change in Accounting Estimate
     During the first quarter of 2011, the Company completed a review of the estimated useful life of its surgical instrument sets. Based on historical useful life information, as well as forecasted product life cycles and demand expectations, the useful life of certain surgical instrument sets was extended from three to four years. In accordance with authoritative guidance, this was accounted for as a change in accounting estimate and was made on a prospective basis effective January 1, 2011. For the three and six months ended June 30, 2011, depreciation expense, which is included in sales, marketing and administrative expenses, was lower by approximately $2.1 million and $3.8 million, respectively, than it would have been had the useful life of these assets not been extended. The effect of this change on basic and diluted earnings per share for the three and six months ended June 30, 2011 was $0.03 and $0.05 per share, respectively.

Reclassifications and Adjustments
     Certain reclassifications have been made to the prior year condensed consolidated financial statements to conform to the current year presentation.
     During the three months ended June 30, 2011, the Company identified an immaterial error in the consolidated financial statements for the year ended December 31, 2010 related to the accrual of payroll expenses. Based on a quantitative and qualitative analysis of the error as required by authoritative guidance, management concluded that the correction, which increased expenses by approximately $1.3 million in the three and six months ended June 30, 2011, had no material impact on any of the Company’s previously issued financial statements, would be immaterial to the expected full year results for 2011 and had no effect on the trend of financial results. Of the $1.3 million, approximately $1.0 million and $0.3 million was charged to sales, marketing and administrative expenses and research and development expenses, respectively.
2. Significant Accounting Policies
Derivative Financial Instruments
     On June 28, 2011, the Company issued $402.5 million principal amount of 2.75% Senior Convertible Notes due 2017 (the 2017 Notes). The 2017 Notes may be settled only in cash unless stockholder approval is obtained to increase the number of the Company’s authorized shares of common stock. If such approval is obtained, the Company may settle the 2017 Notes in cash, stock, or a combination thereof. In accordance with authoritative guidance, the cash conversion feature of the 2017 Notes (the 2017 Notes Embedded Conversion Derivative) requires bifurcation from the 2017 Notes and is accounted for as a derivative liability, which is included in long-term liabilities in the Company’s condensed consolidated balance sheet.
     In connection with the issuance of the 2017 Notes, the Company entered into convertible note hedge transactions (the 2017 Hedge) entitling the Company, assuming stockholder approval is obtained to increase the number of the Company’s authorized shares of common stock as discussed above, to purchase up to 9,553,096 shares of the Company’s common stock at an initial stock price of $42.13 per share, each of which is subject to adjustment. Until stockholder approval is obtained to increase the number of the Company’s authorized shares of common stock, the 2017 Hedge may be settled only in cash. In accordance with authoritative guidance, the 2017 Hedge is accounted for as a derivative asset, which is included in long-term assets in the Company’s condensed consolidated balance sheet.
     The Company recognizes all derivative instruments as assets or liabilities in its balance sheet and measures these instruments at fair value by “marking-to-market” these assets and liabilities at the end of each reporting period. Gains and losses are recorded as a component of Other income (expense), net. As the fair values of the 2017 Notes Embedded Conversion Derivative and the 2017 Hedge on June 28, 2011 approximate their respective fair values as of June 30, 2011, no such gains or losses were recorded for the three and six months ended June 30, 2011.
Recently Adopted Accounting Standards
Fair Value Measurements Disclosures
     Effective January 1, 2011, the Company adopted the FASB’s updated guidance related to fair value measurements and disclosures, which requires a reporting entity to disclose separately information related to purchases, sales, issuances, and settlements in the reconciliation for fair value measurements using significant unobservable inputs, or Level 3, to be included in the rollforward of activity. The guidance is effective for interim or annual financial reporting periods beginning after December 15, 2010. The Company has updated its disclosures to comply with the updated guidance; however, adoption of the updated guidance did not have an impact on the Company’s consolidated results of operations or financial position.

3. Investment in Progentix Orthobiology, B.V.
     In 2009, the Company completed the purchase of forty percent (40%) of the capital stock of Progentix, a company organized under the laws of the Netherlands, from existing shareholders (the Progentix Shareholders) pursuant to a Preferred Stock Purchase Agreement for $10 million in cash (the Initial Investment). Concurrent with the Initial Investment, NuVasive and Progentix also entered into a Senior Secured Facility Agreement, whereby Progentix may borrow up to $5 million from NuVasive to fund ongoing clinical and regulatory efforts (the Loan). At June 30, 2011, the Company had advanced Progentix the full $5.0 million in accordance with the Loan Agreement. The Loan accrues interest at a rate of six percent (6%) per year. Other than its obligations under the Loan Agreement, NuVasive is not obligated to provide additional funding, nor has any additional funding been provided, to Progentix.
     Also concurrent with the Preferred Stock Purchase Agreement, NuVasive, Progentix and the Progentix Shareholders entered into an Option Purchase Agreement, as amended (the Option Agreement), whereby NuVasive may be obligated (the Put Option), upon the achievement of an annual sales run rate on Progentix products in excess of a specified amount between June 14, 2011 and June 13, 2013 (the Option Period), to purchase the remaining sixty percent (60%) of capital stock of Progentix from its shareholders (the Remaining Shares) for an amount up to $35.0 million, subject to certain adjustments, payable in a combination of cash and NuVasive common stock, at NuVasive’s sole discretion. In accordance with the Option Agreement, NuVasive has the right to purchase the Remaining Shares (the Call Option) during the Option Period for an amount up to $35.0 million, subject to certain adjustments, payable in a combination of cash and NuVasive common stock, at NuVasive’s sole discretion. Also in accordance with the Option Agreement, an option expired in June 2011 that could have required NuVasive to purchase the Remaining Shares and make additional milestone related payments totaling up to $70 million, subject to certain adjustments. NuVasive and Progentix also entered into a Distribution Agreement, as amended, whereby Progentix appointed NuVasive as its exclusive distributor for certain Progentix products. The Distribution Agreement will be in effect for a term of ten years unless terminated earlier in accordance with its terms.
     In accordance with authoritative guidance issued by the FASB, the Company has determined that Progentix is a variable interest entity (VIE) as it does not have the ability to finance its activities without additional subordinated financial support and its equity investors will not absorb their proportionate share of expected losses and will be limited in the receipt of the potential residual returns of Progentix. Additionally, pursuant to this guidance, NuVasive is considered its primary beneficiary as NuVasive has both (1) the power to direct the economically significant activities of Progentix and (2) the obligation to absorb losses of, or the right to receive benefits from, Progentix. Accordingly, the financial position and results of operations of Progentix have been included in the Company’s consolidated financial statements from the date of the Initial Investment. The liabilities recognized as a result of consolidating Progentix do not represent additional claims on the Company’s general assets. The creditors of Progentix have claims only on the assets of Progentix, which are not material, and the assets of Progentix are not available to NuVasive.
     Pursuant to authoritative guidance, the equity interests in Progentix not owned by the Company, which includes shares of both common and preferred stock, are reported as noncontrolling interests on the consolidated balance sheet of the Company. The preferred stock represents 18% of the noncontrolling equity interests and provides for a cumulative 8% dividend, if and when declared by Progentix’s Board of Directors. As the rights and conversion features of the preferred stock are substantially the same as those of the common stock, the preferred stock is classified as noncontrolling interest and shares in the allocation of the losses incurred by Progentix. Losses incurred by Progentix are charged to the Company and to the noncontrolling interest holders based on their ownership percentage. The Remaining Shares and the Option Agreement that was entered into between NuVasive, Progentix and the Progentix Shareholders are not considered to be freestanding financial instruments as defined by authoritative guidance. Therefore the Remaining Shares and the Option Agreement are accounted for as a combined unit on the consolidated financial statements as a redeemable noncontrolling interest that was initially recorded at fair value and classified as mezzanine equity.

The Company reviews the components of its inventory on a periodic basis for excess, obsolete or impaired inventory, and records a reserve for the identified items.
5. Marketable Securities and Fair Value Measurements
     Marketable securities consist of certificates of deposit, corporate debt securities, U.S. government treasury securities and securities of government-sponsored entities. The Company classifies all securities as available-for-sale, as the sale of such securities may be required prior to maturity to implement management strategies. These securities are carried at fair value, with the unrealized gains and losses reported as a component of other comprehensive income in stockholders’ equity until realized. A decline in the market value of any marketable security below cost that is determined to be other than temporary will result in a revaluation of its carrying amount to fair value. The impairment is charged to earnings and a new cost basis for the security is established. No such impairment charges were recorded for any period presented.
     Realized gains and losses from the sale of marketable securities, if any, are determined on a specific identification basis. Realized gains and losses and declines in value judged to be other-than-temporary, if any, on available-for-sale securities are included in other income or expense on the consolidated statements of income. Realized gains and losses during the periods presented were immaterial. Premiums and discounts are amortized or accreted over the life of the related security as an adjustment to yield using the straight-line method and are included in interest income on the consolidated statements of income. Interest and dividends on securities classified as available-for-sale are included in interest income on the consolidated statements of income.

     As of June 30, 2011, the Company had no significant investment positions that were in an unrealized loss position. The Company reviews its investments to identify and evaluate investments that have an indication of possible other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary include the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee, and the Company’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. The Company maintains an investment portfolio of various holdings, types and maturities. The Company does not have derivative financial investments. The Company places its cash investments in instruments that meet high credit quality standards, as specified in its investment policy guidelines. These guidelines also limit the amount of credit exposure to any one issue, issuer or type of instrument.
     The Company measures certain assets and liabilities in accordance with authoritative guidance which requires fair value measurements 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.

Table of Contents

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 Level 1 and Level 2 and no transfers to or from Level 3 of the fair value measurement hierarchy during the six months ended June 30, 2011.
     The fair values of the Company’s assets and liabilities at June 30, 2011, which are measured at fair value on a recurring basis, were determined using the following inputs (in thousands):

The fair and carrying value of the Company’s Senior Convertible Notes is discussed in Note 7.
Contingent Consideration Liability
     In connection with the acquisition of Cervitech®, Inc. (Cervitech) in May 2009, the Company is required to pay an additional amount not to exceed $33.0 million in the event that the PCM® cervical total disc replacement device receives U.S. Food and Drug Administration approval. The fair value of the contingent consideration is determined using a probability-weighted discounted cash flow model, the significant inputs which are not observable in the market. The key assumptions in applying this approach are the interest rate, the timing of expected approval and the probability assigned to the milestone being achieved. Based on the expected timing of the milestone being achieved, the estimated fair value of the contingent consideration increased to $32.5 million at June 30, 2011. Changes in fair value are recorded in the statement of income as sales, marketing and administrative expenses.
     In connection with an immaterial acquisition in 2010, the Company is required to pay an additional amount not to exceed $3.0 million in the event three specified milestones are met. The fair value of the contingent consideration is determined using a probability-weighted discounted cash flow model, the significant inputs of which are not observable in the market. The key assumptions in applying this approach are the interest rate and the probabilities assigned to the milestones being achieved. Based on the probabilities assigned to the milestones being achieved, the estimated fair value of the contingent consideration totaled $1.5 million at June 30, 2011. Changes in fair value are recorded in the statement of income as sales, marketing and administrative expenses.
Derivative Financial Instruments
     The Convertible note hedge derivative (the 2017 Hedge) and the Embedded conversion derivative (the 2017 Notes Embedded Conversion Derivative) are classified as Level 3 because these assets and liabilities are not actively traded and are valued using significant

     2.75% Senior Convertible Notes due 2017
     In June 2011, the Company issued $402.5 million principal amount of 2.75% Senior Convertible Notes due 2017 (the 2017 Notes), which includes the issuance of $52.5 million principal amount for the exercise of the initial purchasers’ option to purchase additional notes. The net proceeds from the offering, after deducting initial purchasers’ discounts and costs directly related to the offering, were approximately $359.0 million. The 2017 Notes have a stated interest rate of 2.75%, mature on July 1, 2017 and may be settled only in cash, unless stockholder approval is obtained to increase the number of the Company’s authorized shares of common stock. Interest on the 2017 Notes began accruing in June 2011 and is payable semi-annually each January 1st and July 1st, beginning January 1, 2012. The fair value, based on quoted market prices, of the outstanding 2017 Notes at June 30, 2011 is approximately $402.6 million.
     Assuming the Company has received stockholder approval to increase the number of the Company’s authorized shares of common stock, the Company will settle conversions of the 2017 Notes by paying or delivering, as the case may be, cash, shares of common stock, or a combination of cash and shares of common stock, solely at the Company’s election. The initial conversion rate of the 2017 Notes is 23.7344 shares per $1,000 principal amount, subject to adjustment (which represents an initial conversion price of approximately $42.13 per share).
     Prior to January 1, 2017, holders may convert their notes only under the following conditions: a) During any calendar quarter beginning October 1, 2011, if the reported sale price of the Company’s common stock for at least 20 days of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is 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 2017 Notes falls 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 2017 Notes. From January 1, 2017 and until the close of business on the second scheduled trading day immediately preceding the July 1, 2017, holders may convert their 2017 Notes at any time, regardless of the foregoing circumstances. The Company may not redeem the 2017 Notes prior to maturity.

     Other than restrictions relating to certain fundamental changes and consolidations, mergers or asset sales and customary anti-dilution adjustments, the 2017 Notes do not contain any financial covenants and do not restrict the Company from paying dividends or issuing or repurchasing any of its other securities.
     In accordance with authoritative guidance, the cash conversion feature of the 2017 Notes (the 2017 Notes Embedded Conversion Derivative) requires bifurcation from the 2017 Notes and is accounted for as a derivative liability, which is included in long-term liabilities in the Company’s condensed consolidated balance sheet. The fair value of the 2017 Notes Embedded Conversion Derivative at the time of issuance of the 2017 Notes was $88.9 million, and was recorded as the original debt discount for purposes of accounting for the debt component of the 2017 Notes. This discount will be recognized as interest expense using the effective interest method over the term of the 2017 Notes. The estimated fair value of the 2017 Notes Embedded Conversion Derivative was $88.9 million as of June 30, 2011.
     In connection with the offering of the 2017 Notes, the Company entered into convertible note hedge transactions (the 2017 Hedge) with the initial purchasers and/or their affiliates (the Counterparties) entitling the Company, assuming stockholder approval is obtained to increase the number of the Company’s authorized shares of common stock as discussed previously, to purchase up to 9,553,096 shares of the Company’s common stock at an initial stock price of $42.13 per share, each of which is subject to adjustment. Until stockholder approval of an increase in the number of the Company’s authorized common shares is obtained, the 2017 Hedge may be settled only in cash. Assuming stockholder approval is obtained, the 2017 Hedge is expected to reduce the potential equity dilution upon conversion of the 2017 Notes if the daily volume-weighted average price per share of the Company’s common stock exceeds the strike price of the 2017 Hedge. The 2017 Hedge is accounted for as a derivative asset, and is included in long-term assets in the Company’s condensed consolidated balance sheet. The cost of the 2017 Hedge was $80.1 million, which also represents its estimated fair value as of June 30, 2011. The 2017 Hedge expires on July 1, 2017.
     The 2017 Notes Embedded Conversion Derivative and the 2017 Hedge are adjusted to fair value each reporting period and gains and losses are recorded in the Company’s condensed consolidated statements of income. As the fair values of the 2017 Notes Embedded Conversion Derivative and the 2017 Hedge on June 28, 2011 approximate their respective fair values as of June 30, 2011, no such gains or losses were recorded during the three and six months ended June 30, 2011.
     In addition, the Company sold warrants to the Counterparties to acquire up to 477,654 shares of the Company’s Series A Participating Preferred Stock (the 2017 Warrants), at an initial strike price of $988.51 per share, subject to adjustment. If the Company receives the necessary stockholder approvals to increase the number of common shares available for issuance, each share of Series A Participating Preferred Stock is initially convertible into 20 shares of the Company’s common stock. The 2017 Warrants expire on various dates from September 2017 through January 2018 and may be settled in cash or net shares. The Company received $47.9 million in cash proceeds from the sale of the 2017 Warrants, which has been recorded as an increase in additional paid-in-capital. The 2017 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 (the quarter or year-to-date period) exceeds the strike price of the 2017 Warrants.
     2.25% Senior Convertible Notes due 2013
     In March 2008, the Company issued $230.0 million principal amount of 2.25% unsecured Senior Convertible Notes (the 2013 Notes), which includes the subsequent exercise of the initial purchasers’ option to purchase an additional $30.0 million aggregate principal amount of the 2013 Notes. The net proceeds from the offering, after deducting the initial purchasers’ discounts and costs directly related to the offering, were approximately $208.4 million. The Company pays 2.25% interest per annum on the principal amount of the 2013 Notes, payable semi-annually in arrears in cash on March 15 and September 15 of each year. Any of the 2013 Notes not converted prior to March 15, 2013, the Maturity Date, will be paid in cash. The fair value, based on quoted market prices, of the outstanding 2013 Notes at June 30, 2011 is approximately $240.1 million.
     The 2013 Notes are convertible into shares of the Company’s common stock, based on an initial conversion rate, subject to adjustment, of 22.3515 shares per $1,000 principal amount of the 2013 Notes (which represents an initial conversion price of approximately $44.74 per share). Holders may convert their 2013 Notes at their option on any day up to and including the second scheduled trading day immediately preceding the Maturity Date. If a fundamental change to the Company’s business occurs, as defined in the 2013 Notes, holders of the 2013 Notes have the right to require that the Company repurchase the 2013 Notes, or a portion thereof, at the principal amount plus accrued and unpaid interest.

Table of Contents

     In connection with the offering of the 2013 Notes, the Company entered into convertible note hedge transactions (the 2013 Hedge) with the initial purchasers and/or their affiliates (the 2013 Counterparties) entitling the Company to purchase up to 5.1 million shares of the Company’s common stock at an initial stock price of $44.74 per share, each of which is subject to adjustment. In addition, the Company sold to the 2013 Counterparties warrants to acquire up to 5.1 million shares of the Company’s common stock (the 2013 Warrants), at an initial strike price of $49.13 per share, subject to adjustment. The cost of the 2013 Hedge that was not covered by the proceeds from the sale of the 2013 Warrants was approximately $14.0 million and was recorded as a reduction of additional paid-in capital as of December 31, 2008. The impact of the 2013 Hedge is to raise the effective conversion price of the 2013 Notes to approximately $49.13 per share (or approximately 20.3542 shares per $1,000 principal amount of the 2013 Notes). The 2013 Hedge is expected to reduce the potential equity dilution upon conversion of the 2013 Notes if the daily volume-weighted average price per share of the Company’s common stock exceeds the strike price of the 2013 Hedge. The 2013 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 (the quarter or year to date period) exceeds the strike price of the 2013 Warrants.
8. Series A Preferred Securities
     On June 28, 2011, in connection with the issuance of the 2017 Warrants, the Company amended its Restated Certificate of Incorporation to designate 477,654 shares of the Company’s authorized preferred stock, par value $0.001 per share, as Series A Participating Preferred Stock (the Series A Preferred Stock). The Series A Preferred Stock will automatically convert into shares of the Company’s common stock if the Company receives the necessary stockholder approvals to increase the number of common shares available for issuance. If the Company has not received such stockholder approvals before the 2017 Warrants are converted into Series A Preferred Stock, the shares of Series A Preferred Stock will accumulate cash dividends at specified dividend rates, beginning on June 1, 2012, for as long as such shares remain outstanding.
     The holders of Series A Preferred Stock (collectively, the “Preferred Holders”) are entitled to receive dividends when and if declared by the Board of Directors. The preferred dividends are payable in preference and in priority to any dividends on the Company’s common stock.
     Shares of Series A Preferred Stock are convertible into 20 shares of common stock, subject to certain antidilution adjustments. Preferred Holders vote on an equivalent basis with common stockholders on an as-converted basis.
     The Preferred Holders are entitled to receive liquidation preferences at the rate of $648.20 per share. Liquidation payments to the Preferred Holders have priority and are made in preference to any payments to the holders of common stock.
     If the necessary stockholder approvals to increase the number of common shares available for issuance are not obtained prior to June 1, 2012, and dividends have not been paid on the shares of Series A Preferred Stock for an aggregate of six quarterly dividend periods or more, the Preferred Holders are entitled to elect two members to the Company’s Board of Directors.
9. Net 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 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 restricted stock units, warrants and the shares to be issued upon the conversion of the 2013 Notes. No shares related to the assumed conversion of the 2013 Notes were included in the diluted net income calculation for the three and six months ended June 30, 2011 and 2010 because the inclusion of such shares would have had an anti-dilutive effect. The shares to be issued upon exercise of all outstanding warrants were excluded from the diluted net income calculation for the three and six months ended June 30, 2011 and 2010 because the inclusion of such shares would have had an anti-dilutive effect.

11. Stock-Based Compensation
     The Company estimates the fair value of stock options and shares issued to employees under the Employee Stock Purchase Plan (ESPP Plan) using a Black-Scholes option-pricing model on the date of grant. The fair value of restricted stock units (RSUs) is based on the stock price on the date of grant. The fair value of equity instruments that are expected to vest are recognized and amortized on an accelerated basis over the requisite service period.

     The Company issued 71,000 and 96,000 shares of common stock upon exercise of stock options during the three and six months ended June 30, 2011, respectively, and issued 524,000 shares of common stock upon exercise of stock options during the year ended December 31, 2010. The Company issued 20,000 and 120,000 shares of common stock upon the vesting of RSUs during the three and six months ended June 30, 2011, respectively, and issued 73,000 shares of common stock upon the vesting of RSUs during the year ended December 31, 2010.
12. Income Taxes
     The Company recorded income tax expense of $4.8 million and $0.6 million for the three months ended June 30, 2011 and 2010, respectively, and $6.3 million and $1.4 million for the six months ended June 30, 2011 and 2010, respectively. The effective income tax rate for the six months ended June 30, 2011 was 47%, which is based on an estimate of the Company’s annual effective income tax rate. The Company updates its annual effective income tax rate each quarter and if the estimated effective income tax rate changes, a cumulative adjustment is made. The annual effective income tax rate for 2011 is expected to be higher than the U.S. federal statutory rate of 35% primarily due to state income taxes, net of federal benefit, estimates for certain non-deductible expenses, and foreign losses expected to be incurred for which no benefit can be recorded.
     There was no material change to the Company’s unrecognized tax benefits and interest accrued related to unrecognized tax benefits during the six months ended June 30, 2011.
13. Business Segment and Product Information
     The Company’s business operates in one segment based upon the Company’s organizational structure, the way in which the operations are managed and evaluated and the lack of availability of separate financial results. Substantially all of the Company’s assets and sales are in the United States.

14. Legal Proceedings
     Medtronic Sofamor Danek USA, Inc. Litigation
     In August 2008, Medtronic Sofamor Danek USA, Inc. and its related entities (Medtronic) filed suit against NuVasive in the United States District Court for the Southern District of California (Medtronic Litigation), alleging that certain of NuVasive’s products infringe, or contribute to the infringement of, twelve U.S. patents assigned or licensed to Medtronic. Three of the patents were later withdrawn by Medtronic, leaving nine patents. NuVasive brought counterclaims against Medtronic alleging infringement of certain of NuVasive’s patents. The case has been administratively broken into serial phases. The initial phase of the case includes three Medtronic patents and one NuVasive patent. Trial on the initial phase of the case is scheduled to begin August 30, 2011. A full schedule for the second phase of the lawsuit has not yet been set by the Court. NuVasive believes its own claims have merit and that Medtronic’s claims lack merit. At June 30, 2011, the probable outcome of this litigation cannot be determined, nor can the Company estimate a range of potential loss. Accordingly, in accordance with the authoritative guidance on the evaluation of contingencies, the Company has not recorded an accrual related to this litigation.
     Trademark Infringement Litigation
     In September 2009, Neurovision Medical Products, Inc. (NMP) filed suit against NuVasive in the U.S. District Court for the Central District of California (Case No. 2:09-cv-06988-R-JEM) alleging trademark infringement and unfair competition. NMP sought cancellation of NuVasive’s “NeuroVision” trademark registrations, injunctive relief and damages based on NMP’s common law use of the “Neurovision” mark. On November 23, 2009, the Company denied the allegations in NMP’s complaint. After trial of the matter, on October 25, 2010 an unfavorable jury verdict was delivered against the Company relating to its use of the NeuroVision trade name. The verdict awarded damages to NMP of $60.0 million. On January 3, 2011, the Court ordered a judgment be entered in the case in the amount of $60.0 million, and granted a permanent injunction prohibiting the Company’s use of the NeuroVision name for marketing purposes. The Company sought emergency relief, and on February 3, 2011, the Ninth Circuit Court of Appeals stayed enforcement of the injunction. The Company intends to timely appeal the judgment and permanent injunction. During pendency of the appeal, the Company has been required to escrow funds to secure the amount of the judgment, plus interest, attorneys’ fees and costs. On June 16, 2011, the Company entered into an escrow arrangement and transferred $62.5 million of cash and investments into a restricted escrow account. These funds are included in restricted cash and investments on the Company’s June 30, 2011 condensed consolidated balance sheet. Any payment of damages will be delayed while the appeals process runs its course, which could take up to two years. The Company continues to believe that the verdict is not supported by the facts or by applicable law. The Company, based on its own assessment as well as that of outside counsel, believes that the trial court committed a number of prejudicial legal errors and that these errors were significant, making the possibility of reversal of the judgment on appeal and/or a new trial probable. Accordingly, at June 30, 2011, in accordance with the authoritative guidance on the evaluation of contingencies, the Company has not recorded an accrual related to this litigation. The Company may be required to record an expense related to this damage award in the future.
     Contingencies
     The Company is party to certain claims and legal actions arising in the normal course of business. The Company does not expect any such claims and legal actions to have a material adverse effect on its business, results of operations or financial condition.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations
Forward-Looking Statements May Prove Inaccurate
     You should read the following discussion of our financial condition and results of operations in conjunction with the unaudited condensed consolidated financial statements and the notes to those statements included in this report. This discussion may contain forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of certain factors, such as those set forth under heading “Risk Factors,” and elsewhere in this report, and similar discussions in our other Securities and Exchange Commission filings, including our Annual Report on Form 10-K for the year ended December 31, 2010. We do not intend to update these forward looking statements to reflect future events or circumstances.
Overview
     We are a medical device company focused on developing minimally disruptive surgical products and procedures for the spine. Our currently-marketed product portfolio is focused on applications for spine fusion surgery, including biologics, a combined market estimated to exceed $7.7 billion globally in 2011. Our principal product offering includes a minimally disruptive surgical platform called Maximum Access Surgery, or MAS®, as well as a growing offering of biologics, cervical and motion preservation products. Our spine surgery product line offerings, which include products for the thoracolumbar spine, the cervical spine, and a set of motion preservation product offerings still under development, are primarily used to enable access to the spine and to perform restorative and fusion procedures in a minimally disruptive fashion. Our biologic product line offerings include allograft (donated human tissue), Osteocel® Plustm, an allograft cellular matrix containing viable mesenchymal stem cells, or MSCs, to aid in spinal fusion, and FormaGraft®, a collagen synthetic product used to aid the fusion process. We focus significant research and development efforts to expand our MAS product platform, advance the applications of our unique technology to additional procedures and develop motion preserving products such as our total disc replacement products. We dedicate significant resources toward training spine surgeons on our unique technology and products. Currently, we are training over 500 surgeons annually, which includes surgeons new to our MAS product platform as well as surgeons previously trained on our MAS product platform who are attending advanced training programs.
     Our MAS platform, with the unique advantages provided by our nerve monitoring systems, enables an innovative lateral procedure known as eXtreme Lateral Interbody Fusion, or XLIF®, in which surgeons access the spine for a fusion procedure from the side of the patient’s body, rather than from the front or back. Our MaXcess® instruments provide access to the spine in a manner that affords direct visualization and our nerve monitoring systems allow surgeons to avoid critical nerves.
     In the past certain insurance providers have adopted policies of not providing reimbursement for the XLIF procedure. We have worked with our surgeon customers and certain surgical societies who, in turn, have worked with these insurance providers to supply the information required to categorize the XLIF procedure as a procedure entitled to reimbursement under their policies. Most major insurance companies provide reimbursement for XLIF procedures, however certain smaller regional carriers have policies against coverage of XLIF. NuVasive cannot offer definitive time frames or final outcomes regarding reversal of the non-coverage policies, as the process is dictated by the third-party insurance providers. To date, we have not experienced significant lack of payment for our procedures based on these policies.
     Factors arising from third parties such as prolonged interaction with regulatory agencies, general pushback from private payers on any of our procedures, devices, or services, industry specific taxes, and other external factors may have a material impact on our business. We have begun to incur incremental expenditures to address these types of issues regionally and nationally as deemed necessary. Such advocacy for improvements in the regulatory approval process, payer coverage of new technologies, and policies that facilitate innovation to improve spine care are likely to become an ongoing expense.
     In recent years, we have significantly expanded our product offering relating to procedures in the cervical spine as well as in the area of biologics. Our cervical product offering now provides a full set of solutions for cervical fusion surgery, including both allograft and CoRoent® implants, as well as cervical plating and posterior fixation products. In 2009, we acquired Cervitech®, Inc. (Cervitech), a company focused on gaining regulatory approval of the PCM® cervical disc system, a motion preserving total disc replacement device. This strategic acquisition allows us the potential to accelerate our entry into the growing mechanical cervical disc replacement market. In the first quarter of 2010, we filed a PMA application with the U.S. Food and Drug Administration (FDA) for

approval of the PCM cervical disc system. Approval, if obtained, would further strengthen our cervical product offering and should enable us to continue our trend of increasing our market share.
     In 2009 we purchased forty percent (40%) of the capital stock of Progentix Orthobiology, B.V. (Progentix), a company organized under the laws of the Netherlands, from existing shareholders for $10.0 million in cash (the Initial Investment). Progentix has as its objective the development and exploitation of knowledge and technology in the field of synthetic bone graft materials to aid in the healing and generation of human bone.
     We have an active product development pipeline focused on expanding our current fusion product platform as well as products designed to preserve spinal motion.
     The majority of our revenues are derived from the sale of disposables and implants, and we expect this trend to continue for the foreseeable future. We loan our proprietary software-driven nerve monitoring systems and surgical instrument sets at no cost to surgeons and hospitals that purchase disposables and implants for use in individual procedures. In addition, we place our proprietary software-driven nerve monitoring systems, MaXcess and other MAS or cervical surgical instrument sets with hospitals for an extended period at no up-front cost to them. Our implants and disposables are currently sold and shipped from our primary distribution and warehousing operations facility located in Memphis, Tennessee. We recognize revenue for disposables or implants used upon receiving acknowledgement of a purchase order from the hospital indicating product use or implantation. In addition, we sell an immaterial number of MAS instrument sets, MaXcess devices, and our proprietary software-driven nerve monitoring systems. To date, we have derived less than 5% of our total revenues from these sales.
     Through June 30, 2011, substantially all of our operations are located in the United States and substantially all of our sales have been generated in the United States. We sell our products in the United States through a sales force comprised of exclusive independent sales agents and our own directly-employed sales professionals; both selling only NuVasive spine surgery products. Our sales force provides a delivery and consultative service to our surgeon and hospital customers and is compensated based on sales and product placements in their territories. Sales force commissions are reflected in our statement of income in the sales, marketing and administrative expense line. We expect to continue to expand our distribution channel. Beginning late in 2007 and continuing today, we are continuing our expansion of international sales efforts with the focus on European, Asian and Latin American markets. Our international sales force is comprised of directly-employed exclusive shareowners as well as exclusive distributors and independent sales agents.
     In June 2011, we issued $402.5 million principal amount of 2.75% Senior Convertible Notes due 2017 (the 2017 Notes), which includes the issuance of $52.5 million principal amount upon the exercise of the initial purchasers’ option to purchase additional notes. The net proceeds from the offering, after deducting initial purchasers’ discounts and costs directly related to the offering, were approximately $359.0 million. We pay 2.75% interest per annum on the principal amount of the 2017 Notes. The 2017 Notes mature on July 1, 2017 and may be settled only in cash, unless stockholder approval is obtained to increase the number of our authorized shares of common stock to allow for conversion of the notes and exercise of warrants issued in connection with the debt offering. Interest on the 2017 Notes began accruing in June 2010 and is payable semi-annually each January 1st and July 1st, beginning January 1, 2012. The completion of this financing transaction affords us greater flexibility and liquidity.

     Our spine surgery product line offerings, which include products for the thoracolumbar spine, the cervical spine, and a set of motion preservation product offerings still under development, are primarily used to enable access to the spine and to perform restorative and fusion procedures in a minimally disruptive fashion. Our biologics product line offerings include allograft (donated human tissue), Osteocel Plus, an allograft cellular matrix containing viable mesenchymal stem cells, or MSCs, to aid in spinal fusion, and FormaGraft, a collagen synthetic product used to aid the fusion process.
     The continued adoption of minimally invasive procedures for spine has led to the continued expansion of our innovative lateral procedure known as eXtreme Lateral Interbody Fusion, or XLIF, in which surgeons access the spine for a fusion procedure from the side of the patient’s body, rather than from the front or back. The execution of our strategy of expanding our product offering for the lumbar region and addressing broader indications further up the spine in the thoracic and cervical regions has contributed to strong revenue growth. In addition, increased market acceptance in our international markets contributed to the increase in revenues noted for the periods presented. We expect the continued adoption of our XLIF procedure and deeper penetration into existing accounts and our newer international markets as our sales force executes on the strategy of selling the full mix of our products; however, recent changes in payer and hospital behavior in the United States have created less predictability in the U.S. lumbar portion of the spine market and impacted the overall spine market’s growth rate. Accordingly, we believe that our growth in revenue in 2011 will be more weighted towards increased sales of our cervical offerings, our biologics product line and in our international businesses.
     Our total revenues increased $13.4 million and $28.8 million in the three and six months ended June 30, 2011, respectively, representing total revenue growth of 11% and 13% for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010. Revenue from our Spine Surgery Products increased $10.9 million and $23.6 million, or 11% and 13%, in the three and six months ended June 30, 2011, respectively compared to the same periods in 2010. Revenue from our Biologics product line increased $2.5 million and $5.1 million, or 11% and 12%, in the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010. Total revenues were impacted by small unfavorable changes in price of approximately 1% and 2% in the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010.

     We expect cost of goods sold, as a percentage of revenue, to remain consistent for the remainder of 2011 at approximately 19% due to the expected continued increased revenue contribution from our lower margin biologics and international businesses, roughly offset by new product introductions that may capture some price premium.

     Sales, marketing and administrative expenses consist primarily of compensation, commission and training costs for personnel engaged in sales, marketing and customer support functions; distributor commissions; depreciation expense for surgical instrument sets; shipping costs; surgeon training costs; shareowner (employee) related expenses for our administrative functions; and third-party professional service fees.
     The increases in sales, marketing and administrative expenses principally result from growth in our revenue and the overall growth of the Company, including: expenses that tend to vary based on revenue such as commissions, depreciation expense for loaned surgical instrument sets, worldwide sales force headcount and shipping; expenses associated with investments in our worldwide infrastructure such as operating systems and real estate; legal expenses; and non-sales related headcount growth, offset by the decrease in depreciation expense due to the change in useful life of certain surgical instrument sets. As a percentage of revenue, sales, marketing and administrative expenses decreased slightly for the three and six months ended June 30, 2011 compared to the same periods in 2010 principally as a result of increased operating leverage in our expenses relative to the 11% and 13% growth in revenue for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010.
     Excluding the impact resulting from a change in an accounting estimate related to the useful life of certain surgical instrument sets, costs that tend to vary based on revenue increased $4.7 million and $6.8 million for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010. These increases include expenses totaling $0.4 million recorded in the three and six months ended June 30, 2011 resulting from the correction of an immaterial error related to the accrual of payroll expenses. This increase is slightly less than our increased revenue growth of 11% and 13% in the first three and six months of 2011 as compared to the same periods in 2010. Effective January 1, 2011, we changed the useful life of certain surgical instrument sets from three to four years. This change, which was accounted for as a change in accounting estimate, resulted in approximately $2.1 million and $3.8 million less depreciation expense for the three and six months ended June 30, 2011, respectively, than would have been recorded had the useful life of these assets not been extended.
     Compensation and other shareowner related expenses for our marketing and administrative support functions increased $1.3 million and $6.6 million for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010 due to increased compensation and other shareowner related expenses resulting from additions to our headcount. These increases include expenses totaling $0.6 million recorded in the three and six months ended June 30, 2011 resulting from the correction of an immaterial error related to the accrual of payroll expenses. Stock-based compensation increased $0.5 million and $2.1 million for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010, primarily related to an increase in stock-based awards granted to shareowners associated with the continued increase in headcount and our fiscal 2011 annual grants.
     In addition to the items discussed above, acquisition-related costs increased $0.6 million and $1.2 million for the three and six months ended June 30, 2011, respectively, compared to the same periods in 2010 primarily attributable to the accretion of the contingent consideration liabilities incurred in the three and six months ended June 30, 2011, and expenses incurred related to other acquisition-related activities. In addition, during the three and six months ended June 30, 2010, expenses were lower due to a recovery

of an international receivable totaling $0.5 million and $1.5 million, respectively, for which no comparable reduction in expenses occurred during the same period in 2011.
     On a long-term basis, as a percentage of revenue, we expect total sales, marketing and administrative costs to continue to decrease moderately over time.

     Research and development expenses consist primarily of product research and development, clinical trial and study costs, regulatory and clinical functions, and shareowner related expenses.
     In the last several years, we have introduced numerous new products and product enhancements that have significantly expanded our MAS platform, enhanced the applications of the XLIF procedure, expanded our offering of cervical products, and moved us closer to entering into the growing motion preservation market. We have also acquired complementary and strategic assets and technology, particularly in the area of biologics. We are developing proprietary total disc replacement devices for lateral lumbar spine applications and separately for cervical spine applications, which are currently in different phases of clinical trials and related studies. We anticipate continuing to incur costs related to such clinical trials and studies through at least 2011.
     Compensation and other shareowner related expenses, including stock-based compensation, decreased $0.3 million for the three months ended June 30, 2011 compared to the same period in 2010 ($0.6 million excluding the impact of expenses totaling $0.3 million recorded in the three months ended June 30, 2011 resulting from the correction of an immaterial error related to the accrual of payroll expenses) primarily due to a decrease in performance-based compensation and stock-based compensation, offset by increased compensation and other shareowner related expenses resulting from additions to the Company’s headcount to support our product development and enhancement efforts. Compensation and other shareowner related expenses, including stock-based compensation, increased $0.6 million for the six months ended June 30, 2011 compared to the same period in 2010 ($0.3 million excluding the impact of expenses totaling $0.3 million recorded in the three months ended June 30, 2011 resulting from the correction of an immaterial error related to the accrual of payroll expenses) primarily due to increased compensation and other shareowner related expenses resulting from additions to the Company’s headcount to support our product development and enhancement efforts, offset by a decrease in stock-based compensation.
     In addition to the items discussed above, expenses for the three and six months ended June 30, 2011 decreased by $1.2 million and $2.0 million, respectively, compared to the same periods in 2010 due to decreased expenses incurred in connection with various clinical trials and studies, which include our PCM cervical disc system. These decreases were offset by an increase in expenses of $0.5 million for the three and six months ended June 30, 2011 compared to the same periods in 2010 related to an asset acquisition-related milestone payment in 2011.
     For the foreseeable future, as a percentage of revenue, we expect total research and development costs to remain around 8% in support of our ongoing development and planned clinical trial and study related activities.

     Amortization of intangible assets relates to amortization of finite-lived intangible assets acquired. Although amortization expense for the three and six months ended June 30, 2011 compared to the same periods in 2010 remained relatively constant, we expect expenses recorded in connection with the amortization of intangible assets to continue to increase in absolute dollars for the foreseeable future as amortization of acquired in-process research and development commences once acquired research and development projects reach technological feasibility.

Interest and other expense, net, for the three and six months ended June 30, 2011 compared to the same periods in 2010 remained relatively constant.
     Interest and other expense, net, is expected to increase in the foreseeable future as a result of the additional cash and non-cash interest expense associated with the 2017 Notes offering which closed on June 28, 2011.

     We recorded income tax expense of $4.8 million and $0.6 million for the three months ended June 30, 2011 and 2010, respectively, and $6.3 million and $1.4 million for the six months ended June 30, 2011 and 2010, respectively. The effective income tax rate for the six months ended June 30, 2011 was 47%, which is based on an estimate of our annual effective income tax rate. We update our annual effective income tax rate each quarter and if the estimated effective income tax rate changes, a cumulative adjustment is made. Our annual effective income tax rate for 2011 is expected to be higher than the U.S. federal statutory rate of 35% primarily due to state income taxes, net of federal benefit, estimates for certain non-deductible expenses, and foreign losses expected to be incurred for which no benefit can be recorded.
     We expect our effective income tax rate to continue to exceed the U.S. federal and state statutory income tax rates primarily due to non-deductible expenses and foreign losses expected to be incurred by Progentix.

     Stock-based compensation related to stock awards is recognized and amortized on an accelerated basis in accordance with authoritative guidance. The increase in stock-based compensation of approximately $0.2 million and $1.7 million for the three and six months ended June 30, 2011 is primarily attributed to an increase in the number of awards granted to shareowners associated with the continued increase in headcount year over year for the periods presented, and the fiscal 2011 annual grants that occurred during the three months ended March 31, 2011.
Liquidity, Cash Flows and Capital Resources
     Since our inception in 1997, we have incurred significant losses and as of June 30, 2011, we had an accumulated deficit of approximately $103.7 million. Through 2008, our operations were funded primarily with proceeds from the sale of our equity securities, which at December 31, 2008, totaled $284.5 million since inception, including $210.1 million sold in the public markets. Since 2009, our operations have been funded primarily with proceeds from our convertible debt financing issued in March 2008, as well as the positive cash flow generated from operations.
     In March 2008, we issued $230.0 million principal amount of 2.25% Senior Convertible Notes due 2013 (the 2013 Notes). The net proceeds from the offering, after deducting the initial purchasers’ discounts and costs directly related to the offering, were approximately $208.4 million. We pay 2.25% interest per annum on the principal amount of the 2013 Notes, payable semi-annually in arrears in cash on March 15 and September 15 of each year. Any 2013 Notes not converted prior to March 15, 2013, the maturity date, will be paid in cash.
     In June 2011, we issued $402.5 million principal amount of the 2017 Notes, which includes the issuance of $52.5 million principal amount upon the exercise of the initial purchasers’ option to purchase additional notes. The net proceeds from the offering, after deducting initial purchasers’ discounts and costs directly related to the offering, were approximately $359.0 million. We pay 2.75% interest per annum on the principal amount of the 2017 Notes. The 2017 Notes mature on July 1, 2017 and may be settled only in cash, unless stockholder approval is obtained to increase the number of our authorized shares of common stock to allow for conversion of the notes and the exercise of warrants issued in connection with the debt offering. Interest on the 2017 Notes began accruing in June 2010 and is payable semi-annually each January 1st and July 1st, beginning January 1, 2012.
     In addition, as more fully discussed in Note 14 to the unaudited condensed consolidated financial statements included in this Report, we were required to escrow funds to secure the recent $60.0 million judgment against us in connection with the NeuroVision trademark infringement litigation. On June 16, 2011, we entered into an escrow arrangement and transferred $62.5 million of cash and investments, representing the $60.0 million judgment amount, plus interest, attorneys’ fees and costs, into a restricted escrow account. These funds are included in restricted cash and investments in our June 30, 2011 condensed consolidated balance sheet.
     Cash, cash equivalents and marketable securities was $524.2 million and $229.7 million at June 30, 2011 and December 31, 2010, respectively. We believe that our existing cash, cash equivalents and short-term marketable securities will be sufficient to meet our anticipated cash needs for at least the next 12 months. Our future capital requirements will depend on many factors including our rate of revenue growth, the timing and extent of spending to support development efforts, the expansion of sales, marketing and administrative activities, the timing of introductions of new products and enhancements to existing products, the continuing market acceptance of our products and the expenditures associated with possible future acquisitions or other business combination transactions.

Table of Contents

     We expect that cash provided by operating activities may fluctuate in future periods as a result of a number of factors, including fluctuations in our operating results and working capital requirements. We have historically invested our cash primarily in U.S. treasuries and government agencies, corporate debt, money market funds, and commercial paper meeting certain criteria. Certain of these investments are subject to general credit, liquidity and other market risks. The general condition of the financial markets and the economy has exacerbated those risks and may affect the value of our current investments and restrict our ability to access the capital markets or even our own funds.
Cash Flows
     The following table summarizes, for the periods indicated, selected items in our condensed consolidated statements of cash flows (in thousands):

Cash flows from operating activities
     Cash provided by operating activities was $27.7 million for the six months ended June 30, 2011, as compared to $25.5 million for the same period in 2010. The $2.2 million increase in cash provided by operating activities for the six months ended June, 30 2011 as compared to the same period in 2010 is primarily due to improved collections from accounts receivable, a decrease in amounts paid to shareowners, and an increase in net income, adjusted for noncash items, offset by the use of $7.9 million more cash to build inventory.
Cash flows from investing activities
     Cash provided by investing activities was $21.6 million for the six months ended June 30, 2011, as compared to cash used in investing activities of $29.0 million for the same period in 2010. The $50.6 million increase in cash provided by investing activities for the six months ended June, 30 2011 as compared to the same period in 2010 is primarily due to a net increase in our net sales of marketable securities of $66.2 million, offset by payments made in connection with a supply agreement, restricted cash investments, and increased purchases of surgical instrument sets which are deployed to support our increasing revenue volume.
Cash flows from financing activities
     Cash provided by financing activities was $363.1 million for the six months ended June 30, 2011, as compared to $5.9 million for the same period in 2010. The $357.3 million increase in cash provided by financing activities for the six months ended June 30, 2011 as compared to the same period in 2010 is primarily due to net proceeds totaling approximately $359.0 million from the issuance of $402.5 million Senior Convertible Notes on June 28, 2011.
Contractual Obligations and Commitments
     Contractual obligations and commitments represent future cash commitments and liabilities under agreements with third parties, including our Senior Convertible Notes, operating leases and other contractual obligations. Our future contractual obligations and commitments are discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010 and there have been no material changes during the six months ended June 30, 2011 except as follows:
     In June 2011, we issued $402.5 million principal amount of the 2017 Notes. We pay 2.75% interest per annum on the

principal amount of the 2017 Notes. The 2017 Notes mature on July 1, 2017 and may be settled only in cash, unless stockholder approval is obtained to increase the number of our authorized shares of common stock to allow for conversion of the notes and the exercise of warrants issued in connection with the debt offering. Interest on the 2017 Notes began accruing in June 2010 and is payable semi-annually each January 1st and July 1st, beginning January 1, 2012.
Critical Accounting Policies and Estimates
     Our discussion and analysis of our financial condition and results of operations is based upon our unaudited condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (GAAP). The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. On an ongoing basis, we evaluate our estimates including those related to bad debts, inventories, valuation of goodwill, intangibles and other long-term assets, income taxes, stock-based compensation, and legal proceedings. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities not readily apparent from other sources. Actual results may differ from these estimates. Our critical accounting policies and estimates are discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010 and there have been no material changes during the six months ended June 30, 2011 except as follows:
Change in Accounting Estimate
     Effective January 1, 2011, we changed the estimated useful lives of instrument sets that we loan to or place with hospitals from three to four years.
Financial Instruments and Fair Value
     Inputs to valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect our market assumptions. These two types of inputs have created the following fair-value hierarchy:
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.
     This hierarchy requires us to minimize the use of unobservable inputs and to use observable market data, if available, when determining fair value. We recognize transfers between levels of this hierarchy based on the fair values of the respective financial instruments at the end of the reporting period in which the transfer occurred. Changes in fair value are recognized in earnings each period for financial instruments that are carried at fair value.
     The types of instruments that trade in markets that are not considered to be active, but are valued based on quoted market prices, broker or dealer quotations, or alternative pricing sources with reasonable levels of price transparency are generally classified within Level 2 of the fair value hierarchy.
     As more fully discussed in Notes 2 and 5 to the unaudited condensed consolidated financial statements included in this Report, in June 2011, in connection with the offering of the 2017 Notes, we entered into convertible note hedge transactions, and recorded an embedded conversion derivative liability. The fair values of these derivatives are determined using an option pricing model based on unobservable inputs and are classified within Level 3. The significant inputs to the model include our stock price, risk free interest rate, bond yield, credit rating, and expected volatility of our stock price.
     Certain contingent consideration liabilities are classified within Level 3 of the fair value hierarchy because they use unobservable inputs. For those liabilities, fair value is determined using a probability-weighted discounted cash flow model, the significant inputs which are not observable in the market.

New accounting requirements
     Effective January 1, 2011, we adopted the FASB’s updated guidance related to fair value measurements and disclosures, which requires a reporting entity to disclose separately information related to purchases, sales, issuances, and settlements in the reconciliation for fair value measurements using significant unobservable inputs, or Level 3, to be included in the rollforward of activity. The guidance is effective for interim or annual financial reporting periods beginning after December 15, 2010. The Company has updated its disclosures to comply with the updated guidance; however, adoption of the updated guidance did not have an impact on our consolidated results of operations or financial position.
Off-Balance Sheet Arrangements
     We have not engaged in any off-balance sheet activities.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
     There has been no material change in the Company’s assessment of its sensitivity to market risk since its presentation set forth in Item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” in its Annual Report on Form 10-K for the fiscal year ended December 31, 2010.
Item 4. Controls and Procedures
     Disclosure Controls and Procedures. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our reports under the Securities Exchange Act of 1934, as amended (Exchange Act), is recorded, processed, summarized and reported within the timelines specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives, and in reaching a reasonable level of assurance, management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.
     Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we carried out an evaluation of the effectiveness of the Company’s disclosure controls and procedures (as such term is defined in Exchange Act Rules 13a — 15(e) and 15d — 15(e)) as of June 30, 2011. Based on such evaluation, our management has concluded that as of June 30, 2011, the Company’s disclosure controls and procedures are effective.
     Changes in Internal Control over Financial Reporting. There has been no change to our internal control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
PART II. OTHER INFORMATION
Item 1. Legal Proceedings
     There have been no material changes to the Legal Proceedings discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010, except as follows:
     As reported by us previously, Medtronic Sofamor Danek USA, Inc. and its related entities (Medtronic), on August 18, 2008, filed a patent infringement lawsuit against NuVasive in the United States District Court for the Southern District of California, alleging that certain of NuVasive’s products or methods, including the XLIF® procedure, infringe, or contribute to the infringement of, twelve U.S. patents. Three of the patents were later withdrawn by Medtronic leaving the following nine patents in the lawsuit: Nos. 5,860,973; 5,772,661; 6,936,051; 6,936,050; 6,916,320; 6,945,933; 6,969,390; 6,428,542; 6,592,586 assigned or licensed to Medtronic (Medtronic Patents). Medtronic is seeking monetary damages and a court injunction against future infringement by NuVasive. NuVasive has answered the complaint denying the allegations, and filed counterclaims seeking dismissal of Medtronic’s complaint and a declaration that NuVasive has not infringed and currently does not infringe any valid claim of the Medtronic Patents.

Additionally, NuVasive has made counterclaims against Medtronic seeking the following relief: (i) Medtronic being permanently enjoined from charging that NuVasive has infringed or is infringing the Medtronic Patents; (ii) a declaration that the Medtronic Patents are invalid; (iii) a declaration that the 5,860,973 and 5,772,661 patents are unenforceable due to inequitable conduct; and (iv) costs and reasonable attorneys’ fees.
     NuVasive filed an amended counterclaim on September 4, 2009, alleging that NuVasive’s U.S. Patent Nos. 7,207,949; 7,582,058; and 7,470,236 are being infringed by Medtronic’s NIM-Eclipse System and accessories and Quadrant products, and DLIF (Direct Lateral Interbody Fusion) surgical technique. Medtronic, on June 23, 2009, filed a request for inter partes reexamination with the Patent Office on NuVasive’s U.S. Patent No. 7,207,949. On October 14, 2009, Medtronic filed a request for inter partes reexamination on NuVasive’s U.S. Patent No. 7,582,058. The Patent Office granted both requests and issued rejections of the claims. Both reexaminations are pending.
     Given the number of patents asserted in the litigation, the parties agreed to proceed on a limited number of patents. The court determined to proceed only with patents that are not the subject of active reexamination proceedings. As a result, the initial phase of the case includes three Medtronic patents and one NuVasive patent. Trial on the initial phase of the case is scheduled to begin August 30, 2011, and is expected to proceed expeditiously. A full schedule for the second phase of the lawsuit has not yet been set by the Court. We cannot determine or predict the probable outcome of this litigation and have therefore not recorded a loss contingency related to this litigation.
Trademark Infringement Litigation
     In September 2009, Neurovision Medical Products, Inc. (NMP) filed suit against NuVasive in the U.S. District Court for the Central District of California (Case No. 2:09-cv-06988-R-JEM) alleging trademark infringement and unfair competition. NMP sought cancellation of NuVasive’s “NeuroVision” trademark registrations, injunctive relief and damages based on NMP’s common law use of the “Neurovision” mark. On November 23, 2009, the Company denied the allegations in NMP’s complaint. After trial of the matter, on October 25, 2010 an unfavorable jury verdict was delivered against the Company relating to its use of the NeuroVision trade name. The verdict awarded damages to NMP of $60.0 million. On January 3, 2011, the Court ordered a judgment be entered in the case in the amount of $60.0 million, and granted a permanent injunction prohibiting the Company’s use of the NeuroVision name for marketing purposes. The Company sought emergency relief, and on February 3, 2011, the Ninth Circuit Court of Appeals stayed enforcement of the injunction, and has consolidated this issue with our appeal of the verdict. During pendency of the appeal, the Company has been required to escrow funds to secure the amount of the judgment, plus interest, attorneys’ fees and costs. On June 16, 2011, the Company entered into an escrow arrangement and transferred $62.5 million of cash and investments into a restricted escrow account. Any payment of damages will be delayed while the appeals process runs its course, which could take up to two years. The Company continues to believe that the verdict is not supported by the facts or by applicable law. The Company, based on its own assessment as well as that of outside counsel, believes that the trial court committed a number of prejudicial legal errors and that these errors were significant, making the possibility of reversal of the judgment on appeal and/or a new trial probable. Accordingly, at June 30, 2011, in accordance with the authoritative guidance on the evaluation of contingencies, the Company has not recorded an accrual related to this litigation. The Company may be required to record an expense related to this damage award in the future.

Risks Related to Our Financial Results and Need for Financing
The sale of our 2.75% Senior Convertible Notes due 2017 significantly increased our amount of long-term debt, and our financial condition and results of operations could be adversely affected if we do not effectively manage our liabilities.
     As described in more detail in Note 7 to our unaudited condensed consolidated financial statements, in June 2011, we issued $402,500,000 aggregate principal amount of our 2.75% convertible senior Notes due 2017 (the 2017 Notes). As a result of the sale of the 2017 Notes, we have a substantially greater amount of long-term debt than we have maintained in the past. Our maintenance of such increased level of debt could adversely affect our flexibility to take advantage of corporate opportunities and could adversely affect our financial condition and results of operations.
Conversion of the 2017 Notes, including under the conditional conversion features of the 2017 Notes, if triggered, may adversely affect our financial condition and operating results.
     The conversion of some or all of the 2017 Notes and any sales in the public market of our common stock issued upon such conversion could adversely affect the market price of our common stock. In addition, the existence of the 2017 Notes may encourage short selling by market participants because the conversion of the 2017 Notes could depress our common stock price.
     In the event the conditional conversion features of the 2017 Notes are triggered, holders of 2017 Notes will be entitled to convert the 2017 Notes during specified periods at their option. If one or more holders elect to convert their 2017 Notes, unless we receive certain necessary stockholder approvals and we elect to satisfy our conversion obligation by delivering solely shares of our common stock, we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders do not elect to convert their 2017 Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the 2017 Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.
Our failure to obtain the requisite stockholder approvals pursuant to the terms of the 2017 Notes and warrants issued in connection therewith could affect our liquidity, financial position and results of operations.
     As described in more detail in Notes 2 and 7 to our unaudited condensed consolidated financial statements, in connection with the issuance of the 2017 Notes, we entered into convertible note hedge transactions (the 2017 Hedge) and issued warrants (the 2017 Warrants) that are exercisable into a number of shares of a new series of our preferred stock, called the Series A participating preferred stock (the “Series A Preferred Stock”), based on the amount, if any, by which the market price per share of our common stock exceeds the strike price of the 2017 Warrants during a measurement period at the maturity of the 2017 Warrants. Pursuant to the terms of the 2017 Notes and 2017 Warrants, we agreed to use our best efforts to hold a meeting of our stockholders as soon as practicable, but not later than June 1, 2012, at which we would seek to obtain the requisite stockholder approval to (i) amend our Restated Certificate of Incorporation to increase the number of authorized but unissued shares of our common stock to permit (1) the conversion and settlement of all 2017 Notes into shares of our common stock and (2) the conversion and settlement, through the delivery of shares of our common stock, of the maximum number of shares of the Series A Preferred Stock issuable upon exercise of the 2017 Warrants and (ii) authorize such conversion and settlement of the Series A Preferred Stock in accordance with NASDAQ Stock Market Rule 5635. If we do not obtain the requisite stockholder approval for these matters:
    the 2017 Notes will not be convertible into shares of our common stock, and we will be required to satisfy our conversion obligation under the 2017 Notes solely in cash;
 
    a gain (or loss) will be reported in our consolidated statement of income to the extent the valuation of the conversion option of the 2017 Notes or the 2017 Hedge changes from the previous period for each financial statement period after issuance of the 2017 Notes or the 2017 Hedge, as applicable;
 
    the Series A Preferred Stock issuable upon settlement of the 2017 Warrants will not convert into shares of our common stock and will accumulate cumulative cash dividends at a rate of up to 16% per annum for so long as such shares remain outstanding;
 
    after June 1, 2012, in addition to the common stock issuable upon conversion of each share of Series A Preferred Stock at the then-applicable conversion rate, on the conversion date, we will pay to the holders to whom we deliver the shares of our common stock due upon conversion cash dividends in an amount equal to all accumulated and unpaid dividends on such share of Series A Preferred Stock, whether or not declared prior to such conversion date, for the then-current dividend period (or portion thereof) ending on such conversion date and all prior dividend periods, if any (other than previously declared dividends on such share of Series A Preferred Stock that were paid to the holder of record of such share of Series A Preferred Stock as of a prior date) to the extent we are lawfully permitted to pay such dividends under Delaware law; and
 
    upon exercise of the 2017 Warrants, the Series A Preferred Stock will remain outstanding and include those rights and preferences set forth in the Series A Preferred Stock certificate of designations, including, but not limited to rights ranking senior to our common stock with respect to dividends and liquidation rights.

     As a result, our failure to obtain the requisite stockholder approval pursuant to the terms of the 2017 Notes and 2017 Warrants could affect our liquidity, financial position and results of operations.
     In addition, if we fail to obtain stockholder approval prior to June 1, 2012, we intend to (i) continue to seek to obtain stockholder approval at each subsequent annual meeting of our stockholders and (ii) hold at least one special meeting of our stockholders in each calendar year, beginning with the 2012 calendar year, at which we will seek to obtain such stockholder approval, in each case, until such approval has been obtained, and we will incur the costs associated therewith.
Risks Related to Our Intellectual Property and Litigation
We are currently involved in several patent litigation actions, including an action involving Medtronic, and, if we do not prevail in this action against Medtronic, we could be liable for past damages and might be prevented from making, using, selling, offering to sell, importing or exporting certain of our products.
     On August 18, 2008, Medtronic Sofamor Danek USA, Inc. and its related entities (Medtronic) filed suit against NuVasive in the United States District Court for the Southern District of California, alleging that certain of our products infringe, or contribute to the infringement of, U.S. patents owned by Medtronic. Medtronic is a large, publicly-traded corporation with significantly greater financial resources than us.
     As further examples of intellectual property risks we face in this industry, on April 20, 2010, we filed a lawsuit against Orthofix, Inc. and its related entities (Orthofix) and Musculoskeletal Transplant Foundation for infringement of a patent licensed as part of our purchase of Osteocel Plus®. In December 2010, the parties entered into a license agreement covering the subject product marketed by Orthofix, Trinity Evolution®, and the lawsuit was settled by the parties. Similarly, on October 5, 2010, we initiated a patent infringement lawsuit against Globus Medical, Inc. (Globus) to protect our investment in our XLIF procedure and MaXcess retractor system. The lawsuit against Globus is in its early stages, and the outcome of this litigation is difficult to predict.
     Intellectual property litigation is expensive, complex and lengthy and its outcome is difficult to predict. A court could enter orders that temporarily, preliminarily or permanently enjoin us or our customers from modeling, using, selling, offering to sell or importing our current or future products, or could enter an order mandating that we undertake certain remedial activities. We may also be subject to negative publicity due to litigation. Pending or future patent litigation against us or any strategic partners or licensees may force us or any strategic partners or licensees to stop or delay developing, manufacturing or selling potential products that are claimed to infringe a third party’s intellectual property, unless we develop alternative non-infringing technology or that party grants us or any strategic partners or licensees rights to use its intellectual property, and may significantly divert the attention of our technical and management personnel. In the event that our right to market any of our products is successfully challenged, or if we fail to obtain a required license or are unable to design around a patent, our business, financial condition or results of operations could be materially adversely affected. In such cases, we may be required to obtain licenses to patents or proprietary rights of others in order to continue to commercialize our products. However, we may not be able to obtain any licenses required under any patents or proprietary rights of third parties on acceptable terms, or at all, and any licenses may require substantial royalties or other payments by us. Even if any strategic partners, licensees or we were able to obtain rights to the third party’s intellectual property, these rights may be non-exclusive, thereby giving our competitors access to the same intellectual property. Furthermore, if we are found to infringe patent claims of a third party, we may, among other things, be required to pay damages, including up to treble damages and attorneys’ fees and costs, which may be substantial.
     An unfavorable outcome for us in patent or other intellectual property litigation could significantly harm our business if such outcome makes us unable to commercialize some of our current or potential products or cease some of our business operations. In addition, costs of defense and any damages resulting from litigation may materially adversely affect our business and financial results. Litigation may also harm our relationships with existing customers and subject us to negative publicity, each of which could harm our business and financial results.
