AMEDICA CORPORATION
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
1. Organization and Summary of Significant Accounting Policies
Organization
Amedica Corporation (“Amedica” or “the Company”) was incorporated in the state of Delaware on December 10, 1996. Amedica is a commercial-stage biomaterials company focused on using its silicon nitride technology platform to develop, manufacture, and commercialize a broad range of medical devices. The Company believes it is the first and only manufacturer to use silicon nitride in medical applications. The Company acquired US Spine, Inc. (“US Spine”), a Delaware incorporated spinal products company with operations in Florida, on September 20, 2010. The Company’s products are sold primarily in the United States.
Basis of Presentation
These unaudited condensed consolidated financial statements have been prepared in accordance with the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Such rules and regulations allow the omission of certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States, so long as the statements are not misleading. In the opinion of management, these financial statements and accompanying notes contain all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position and results of operations for the periods presented herein. These condensed consolidated financial statements should be read in conjunction with the consolidated audited financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 , filed with the SEC on March 24, 2015. The results of operations for the nine months ended September 30, 2015 are not necessarily indicative of the results to be expected for the year ending December 31, 2015 . The Company’s significant accounting policies are set forth in Note 1 to the consolidated audited financial statements in its Annual Report on Form 10-K for the year ended December 31, 2014 .
Use of Estimates
The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates. Some of the more significant estimates relate to inventory, allowance for accounts receivable, stock-based compensation, long-lived and intangible assets and derivative liabilities.
Liquidity and Capital Resources
For the nine months ended September 30, 2015 and 2014, the Company incurred a net loss of $21.4 million and $22.9 million , respectively, and used cash in operations of $7.1 million and $11.4 million , respectively. The Company had an accumulated deficit of $194.1 million and $172.5 million at September 30, 2015 and December 31, 2014 , respectively. To date, the Company’s operations have been principally financed from proceeds from the issuance of preferred and common stock, convertible debt and bank debt and, to a lesser extent, cash generated from product sales. It is anticipated that the Company will continue to generate operating losses and use cash in operations through 2015.
As discussed further in Note 7, the Company has entered into a term loan with Hercules Technology Growth Capital, Inc. (“Hercules Technology”), as administrative and collateral agent for the lenders thereunder and as lender, and Hercules Technology III, LP, as lender (the “Hercules Term Loan”). The Hercules Term Loan has a liquidity covenant that requires the Company to maintain a cash balance of not less than $8.5 million at September 30, 2015. At September 30, 2015 , the Company’s cash balance was approximately $11.3 million . The Company anticipates that it will need to obtain additional funding during the fourth quarter of 2015 to maintain compliance through 2015 with the liquidity covenants related to the Hercules Term Loan. As discussed in Footnote 8 and Footnote 12, the Company received gross proceeds of $5.0 million in November 2015 from the exercise of the Series B Warrants and could potentially raise up to an additional $5.0 million during the fourth quarter of 2015 from the exercise of the Series B and Series C warrants issued in September 2015. However, if the Series C Warrants are not exercised and the Company is unable to access additional funds prior to becoming non-compliant with the financial and liquidity covenants related to the Hercules Term Loan, the entire remaining balance of the debt under the Hercules Term Loan could become immediately due and payable at the option of the lender. Although the Company is seeking additional financing, additional funding may not be available to the Company on favorable or acceptable terms, or at all. Any

6

additional equity financing, if available to the Company, will most likely be dilutive to its current stockholders, and debt financing, if available, may involve more restrictive covenants. The Company’s ability to access capital when needed is not assured and, if not achieved on a timely basis, will materially harm its business, financial condition and results of operations. These uncertainties create substantial doubt about the Company’s ability to continue as a going concern. No adjustment has been made to our financial statements as a result of this uncertainty.
Significant Accounting Policies
There have been no significant changes to the Company’s significant accounting policies as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 .
New Accounting Pronouncements
In May 2014, the Financial Accounting Standards Board (“FASB”) updated the accounting guidance related to revenue from contracts with customers, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. The core principle is that a company should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. The standard defines a five step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing U.S. GAAP. The standard is effective for annual periods beginning after December 15, 2017, and interim periods therein, and shall be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.
In August 2014, the FASB updated the accounting guidance related to disclosure of uncertainties about an entity’s ability to continue as a going concern. The new standard provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. It requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern. The new standard is effective for annual periods ending after December 15, 2016, and interim periods thereafter. Early adoption is permitted. The impact on the Company’s financial statements of adopting the new standard is currently being assessed by management.
In April 2015, the FASB updated the accounting guidance related to simplifying the presentation of debt issuance costs on the balance sheet. The new standard requires that debt issuance costs be presented as a direct deduction from the associated debt liability. It will be effective on January 1, 2016, and early adoption is permitted. The standard will be applied retrospectively to all prior periods presented. The Company expects that the new standard will impact the presentation of its consolidated balance sheet.
2. Basic and Diluted Net Loss per Common Share
Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method. Dilutive common stock equivalents are comprised of warrants for the purchase of common stock, convertible notes, stock options and unvested restricted stock units. For all periods presented, there is no difference in the number of shares used to calculate basic and diluted shares outstanding because their effect would have been anti-dilutive due to the Company reporting a net loss. The Company had potentially dilutive securities representing approximately 45.2 million and 5.8 million shares of common stock at September 30, 2015 and 2014 , respectively.
3. Inventories

5. Fair Value Measurements
Financial Instruments Measured and Recorded at Fair Value on a Recurring Basis
The Company measures and records certain financial instruments at fair value on a recurring basis. Fair value is based on the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, under a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:
Level 1
-
quoted market prices for identical assets or liabilities in active markets.
Level 2
-
observable prices that are based on inputs not quoted on active markets, but corroborated by market data.
Level 3
-
unobservable inputs reflecting management’s assumptions, consistent with reasonably available assumptions made by other market participants. These valuations require significant judgment.
The Company classifies assets and liabilities measured at fair value in their entirety based on the lowest level of input that is significant to their fair value measurement. No financial assets were measured on a recurring basis at September 30, 2015 and December 31, 2014 . The following tables set forth the financial liabilities measured at fair value on a recurring basis by level within the fair value hierarchy at September 30, 2015 and December 31, 2014 :

7. Debt
On June 30, 2014, the Company entered into a Loan and Security Agreement with Hercules which provided the Company with a $20 million term loan. On June 30, 2014, the Company also entered into a Securities Purchase Agreement with Magna pursuant to which the Company sold to Magna an initial unsecured senior convertible note (“Initial Convertible Note”) with an original principal amount of $2.9 million for a purchase price of $2.5 million . Additionally, on August 11, 2014, the Company sold to Magna an additional unsecured senior convertible note (“Additional Convertible Note”) with an original principal amount of $3.5 million for a purchase price of $3.5 million . The Initial Convertible Note and the Additional Convertible Note are collectively referred to as the Magna Convertible Notes.
Hercules Term Loan
The Hercules Term Loan matures on January 1, 2018 . The Hercules Term Loan included a $200,000 closing fee, which was paid to Hercules Technology on the closing date of the loan.  The closing fee was recorded as a debt discount and is being amortized to interest expense over the life of the loan. The Hercules Term Loan also includes a non-refundable final payment fee of $1.7 million .  The final payment fee is being accrued and recorded to interest expense over the life of the loan.
The Hercules Term Loan bears interest at the rate of the greater of either (i) the prime rate plus 7.7% , or (ii) 10.95% .  Interest accrues from the closing date of the loan and interest payments are due monthly. Principal payments commenced August 1, 2015 and are to be made in 30 equal installments of approximately $700,000 , with the remainder due at maturity. The Company’s obligations to Hercules are secured by a first priority security interest in substantially all of its assets, including intellectual property. The Hercules Term Loan contains certain covenants related to restrictions on payments to certain Company affiliates and financial reporting requirements.
On September 8, 2015, the Company entered into a Consent and First Amendment to Loan and Security Agreement (the “Amendment”) with Hercules Technology. The Amendment amended certain terms the Hercules Loan and Security Agreement and granted certain consents to the Company relating to the Settlement Agreement with Magna discussed below. The Amendment provides that if the Company prepays its loan from Hercules, it must pay a prepayment charge of 1.5% of the amount being prepaid until September 8, 2016 and thereafter 0.75% . The Amendment also increased the fee the Company must pay to Hercules upon the maturity of the loan or if it is prepaid from $1.5 million to $1.7 million . Further, the annual interest rate on the loan will increase by 1.5% if the Company does not receive gross proceeds of at least $10.0 million from the exercise of the Series B and Series C Warrants discussed in Footnote 8. As part of the Amendment, Hercules also waived and released its event of default notice sent on June 30, 2015. Additionally, the Amendment reduced the Company’s obligation to maintain cash and cash equivalents of not less than $9.0 million to an amount that varies based on the loan amount. The minimum cash requirement is reduced by $500,000 for every $1.0 million paid in principal to a minimum of $2.5 million . The minimum cash and cash equivalents balance required to maintain compliance with the minimum liquidity covenant at September 30, 2015 was $8.5 million . Although the Company was in compliance with the liquidity covenant at September 30,

10

2015, the Company anticipates that it will be non-compliant with the liquidity covenant during the fourth quarter of 2015 if additional financing is not obtained, and has therefore classified the entire obligation as a current liability.
As part of the Amendment, the warrant held by Hercules was modified to increase the number of underlying shares to 1,548,387 and decrease the exercise price to $0.47 , subject to adjustment. The warrant modification increased the estimated fair value of the warrant by $382,000 , which was recorded as a debt discount and an increase in derivative liability. The debt discount is being amortized over the life of the loan.
Magna Convertible Notes
On April 2, 2015, we entered into an Amendment and Exchange Agreement (the “Amendment Agreement”) with Magna. The Amendment Agreement provides for the issuance by the Company to Magna of two new senior convertible notes, one with a maturity date in June 2016 and one with a maturity date in August 2016 (the "June Note", the "August Note," and collectively the “Exchange Convertible Notes”) in exchange for the Initial Convertible Note, the Additional Convertible Note and a warrant issued to Magna ("Magna Warrant") to purchase 568,889 shares of the Company's common stock at an exercise price of $4.65 . The exchange resulted in the cancellation of the Initial Convertible Note, Additional Convertible Note and Magna Warrant.
On June 19, 2015, the Company received written notice from Magna that an event of default had occurred with respect to the Exchange Convertible Notes and underlying agreements. On September 8, 2015, the Company entered into a Settlement and Waiver Agreement ("Settlement Agreement") with Magna. Pursuant to the Settlement Agreement, the Company paid Magna $2.5 million from the September 2015 Offering discussed in Footnote 8 to redeem the entire $800,000 of outstanding principal amount and accrued interest of the June Note and to partially redeem $1.4 million principal amount of the August Note and any accrued interest. The Company agreed to pay an additional $1.25 million to partially redeem $1.1 million of the remaining principal amount of the August Note and any accrued interest if the Company receives gross proceeds of $5.0 million from the sale of equity securities and up to another $1.25 million to redeem in full the remaining August Note principal balance and interest if the Company receives up to an additional $5.0 million in gross proceeds. As part of the Settlement Agreement, Magna waived its event of default notice delivered to the Company on June 19, 2015 and its right to convert the August Note into shares of common stock.
The Settlement Agreement was accounted for as a debt extinguishment and the Company recorded a gain on extinguishment of debt of $2.4 million . Since the conversion features of the Exchange Convertible Notes were eliminated, the estimated fair value of the conversion features of $3.5 million was extinguished and included in the calculation of the gain on extinguishment of debt.
The outstanding principal amount of the remaining Magna August Note was $2.1 million at September 30, 2015. The Magna August Note matures on August 11, 2016 , and accrues interest at an annual rate of 6.0% .
During the nine months ended September 30, 2015 , Magna converted a total of $202,000 of the principal amount of the Convertible Notes into 373,000 shares of common stock. The Company recorded a loss upon extinguishment of $79,000 during the nine months ended September 30, 2015 related to the conversion into shares of common stock.

8. Equity
September 2015 Offering
In September 2015, the Company entered into a Securities Purchase Agreement whereby it issued to certain investors 13,123,360 shares of common stock at a price of $0.381 per share for gross proceeds of $5.0 million before deducting placement agent fees and related offering expenses. Pursuant to the terms of the Securities Purchase Agreement the company also issued to the investors Series A Warrants, Series B Warrants, Series C Warrants and Series D Warrants. Each of the Series A Warrants, the Series B Warrants and the Series C Warrants are initially exercisable for 13,123,360 shares of common stock with at an initial exercise price of $0.47 per share.
Shareholder approval is required for the issuance of the common shares underlying the Series B Warrants, the Series C Warrants and the Series D Warrants. The Company obtained the requisite shareholder approval for the issuance at a Special Meeting of Stockholders held on November 3, 2015. The Series B and Series C Warrants have automatic exercise provisions if certain conditions are met, which include, the attainment of requisite shareholder approval and the satisfaction of certain other equity trading conditions. The Company could receive up to a maximum of $5.0 million from the exercise of the Series B Warrants and up to a maximum of $5.0 million from the exercise of the Series C Warrants. If the Series B and Series C Warrants are exercised, the Series C exercise price will be the lesser of the current exercise price of $0.47 per share or 75% of the sum of the three lowest closing consolidated bid prices of the common stock during the five trading day period prior to the date on which payment of the exercise price is received by the Company. If, as a result of the application of such formula, the exercise price is adjusted downward from the initial exercise price of $0.47 per share, then the number of common shares issuable upon the exercise of each of the warrants will be increased such that the gross proceeds from exercise of each of the Series B Warrants and Series C Warrants will equal $5.0 million , respectively, or a lesser amount if the warrants are not exercised in full. The Series B Warrants and Series C Warrants expire on November 17, 2015 and December 30, 2015, respectively.
The number of Series A Warrants would increase to match the number of shares of common stock issued upon the exercise of the Series B and Series C Warrants. The Series A Warrants have an exercise price adjustment provision that in the event the Company sells shares of any additional common stock or securities convertible into common stock prior to December 30, 2015, subject to certain exceptions, at a price per share less than the original exercise price of the warrant, the exercise price shall be adjusted to a price equal to the price paid per share for such additional common stock or securities.
The Series A Warrants, Series B Warrant and Series C Warrants are considered to be liabilities and are marked to market at each reporting period until they are exercised or are no longer classified as liabilities. The Company estimated the fair value of these warrants to be $14.4 million . The Company recorded $4.9 million of the $5.0 million gross proceeds from the offering to derivative liabilities and $131,000 to equity and recorded a loss of $9.5 million , which was included in the change in fair value of derivative liabilities per the Condensed Consolidated Statements of Operations and Comprehensive Loss. Furthermore, all of the $821,000 of the September 2015 offering costs were expensed since the value of the warrants exceeded the gross proceeds.
The Company entered into a placement agent agreement in connection with the September 2015 Offering. As part of the placement agent agreement, the Company issued a warrant to the placement agent to purchase 656,168 shares of common stock at an exercise price of $0.47 . The warrant was determined to be a liability and the estimated fair value of $157,000 was included in offering costs.

November 2014 Secondary Offering
On November 26, 2014 , the Company completed a secondary offering, in which the Company sold and issued 11,441,646 units. Each unit was issued at a price of $1.14 and consisted of one share of common stock and one common stock warrant (“Secondary Offering Warrant”). The Company issued an additional 1,716,246 Secondary Offering Warrants pursuant to the underwriters’ over-allotment option.
The Secondary Offering Warrants were immediately exercisable after issuance into common shares at an exercise price of $1.48 and terminate on November 26, 2019 . The Secondary Offering Warrants contain a cashless exercise provision whereby the holders may exercise warrants by paying the exercise price in cash or, in lieu of payment of the exercise price in cash, at any time 120 days after issuance, by electing to receive a cash payment from the Company equal to the Black Scholes Value (as defined below) of the number of shares the holder elects to exercise (the “Black Scholes Payment”); provided that we have discretion as to whether to deliver the Black Scholes Payment or, subject to meeting certain conditions, to deliver a number of shares of our common stock determined according to the following formula (the “Cashless Exercise”):
Total Shares = (A x B) / C
Where:
Total Shares is the number of shares of common stock to be issued upon a Cashless Exercise
A is the total number of shares with respect to which the warrant is then being exercised.
B is the Black Scholes Value (as defined below).
C is the closing bid price of our common stock as of two trading days prior to the time of such exercise.
As defined in the Secondary Offering Warrants, “Black Scholes Value” means the Black Scholes value of an option for one share of our common stock at the date of the applicable Black Scholes Payment or Cashless Exercise, which is calculated using the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg utilizing (i) an underlying price per share equal to the closing bid price of the common stock as of trading day immediately preceding the date of issuance of the warrant, (ii) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of the warrant as of the applicable Black Scholes Payment or Cashless Exercise, (iii) a strike price equal to the exercise price in effect at the time of the applicable Black Scholes Payment or Cashless Exercise, (iv) an expected volatility equal to 135% and (v) a remaining term of such option equal to five years (regardless of the actual remaining term of the warrant).
The Secondary Offering Warrants are considered to be liabilities and are marked to market at each reporting period. During the nine months ended September 30, 2015 , 13,047,372 of the Secondary Offering Warrants had been exercised via the cashless exercise provision resulting in the issuance of 38,202,840 shares of common stock. Had the cashless exercise provision been exercised by all the holders of the remaining 110,520 Secondary Offering Warrants at September 30, 2015 , the Company would have had to either pay $87,000 in cash or issue an additional 274,738 shares of common stock. The number of shares of common stock that would be required to satisfy the cashless exercise provision increases as the price of the Company’s common stock decreases and decreases as the price of the Company’s common stock increases.
Other Issuances
During the nine months ended September 30, 2015 , the Company issued 30,000 shares of common stock to a service provider as consideration for services to be rendered under a consulting agreement. Furthermore, 853,365 shares of common stock were issued upon the conversion of restricted stock units into common stock, of which 206,380 shares of common stock were withheld to satisfy the employees' tax withholding obligations associated with the conversion of the restricted stock units into common stock. The withheld shares were included in treasury stock at a total value of $120,000 , which was based on the market price of the common stock on the date the shares were issued. During June 2015, these treasury shares were issued upon the conversion of restricted stock units into common stock. Additionally, during the nine months ended September 30, 2015 , 242 shares of common stock were issued upon the exercise of warrants.
9. Stock-Based Compensation
Option and Equity Plans
In May 2015, the stockholders of the Company approved an increase in the aggregate number of common shares issuable under the 2012 Employee, Director and Consultant Equity Incentive Plan (the “2012 Plan”) 1,000,000 shares to 4,586,181 shares.
The total number of shares available for grant under the 2012 Plan at September 30, 2015 was 1,483,015 .

The Company estimates the fair value of each stock option on the grant date using the Black-Scholes valuation model, which requires several estimates including an estimate of the fair value of the underlying common stock on grant date. The expected volatility was based on an average of the historical volatility of a peer group of similar companies. The expected term was calculated utilizing the simplified method. The risk-free interest rate was based on the U.S. Treasury yield curve in effect at the time of grant for the expected term of the option. The following weighted average assumptions were used in the calculation to estimate the fair value of options granted to employees nine months ended September 30, 2015 and 2014:

10. Commitments and Contingencies
From time to time, the Company is subject to various claims and legal proceedings covering matters that arise in the ordinary course of its business activities. Management believes any liability that may ultimately result from the resolution of these matters will not have a material adverse effect on the Company’s consolidated financial position, operating results or cash flows.
11. Related-Party Transactions

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our consolidated financial statements for the year ended December 31, 2014 and the notes thereto, along with Management’s Discussion and Analysis of Financial Condition and Results of Operations, included in our Annual Report on Form 10-K for the year ended December 31, 2014, filed separately with the U.S. Securities and Exchange Commission. This discussion and analysis contains forward-looking statements based upon current beliefs, plans, expectations, intentions and projections that involve risks, uncertainties and assumptions. Our actual results and the timing of selected events could differ materially from those anticipated in these forward-looking statements as a result of several factors, including those set forth under the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2014, and any updates to those risk factors filed from time to time in our Quarterly Reports on Form 10-Q, including those set forth under Part II, Item 1A.of this Quarterly Report on Form 10-Q.
Overview
We are a commercial biomaterial company focused on using our silicon nitride technology platform to develop, manufacture and sell a broad range of medical devices. We currently market spinal fusion products and are developing products for use in total hip and knee joint replacements. We believe our silicon nitride technology platform enables us to offer new and transformative products in the orthopedic and other medical device markets. We believe we are the first and only company to use silicon nitride in medical applications. Over 20,000 of our silicon nitride spine products have been implanted in patients.
Biomaterials come in a variety of synthetic or natural materials available in a variety of forms that are used in virtually every medical specialty. We believe our silicon nitride biomaterial has superior characteristics compared to commonly used biomaterials in the markets we are targeting, including polyetheretherketone, or PEEK, which is the most common biomaterial used for interbody spinal fusion products. Specifically, we believe our silicon nitride has the following key attributes: promotion of bone growth; hardness, strength and resistance to fracture; resistance to wear; non-corrosive; anti-infective properties; biocompatibility; and superior diagnostic imaging compatibility.
We currently market our Valeo® family of silicon nitride interbody spinal fusion devices in the United States and Europe for use in the cervical and thoracolumbar areas of the spine. We believe our Valeo devices have a number of advantages over existing products due to silicon nitride’s key characteristics, resulting in faster and more effective fusion and reduced risk of infection.
In addition to our silicon nitride-based spinal fusion products, we market a line of non-silicon nitride spinal fusion products which allows us to provide surgeons and hospitals with a broader range of products. These additional products are complementary to our fusion products and are designed for the treatment of deformity and degenerative spinal procedures. Although our non-silicon nitride products have accounted for approximately 48% and 55% of our product revenues for the nine months ended September 30, 2015 and 2014 , respectively, we believe the continued promotion and potential for adoption of our silicon nitride products and product candidates, if approved, provides us the greatest opportunity to grow our business in new and existing markets and achieve our goal to become a leading biomaterial company.
In addition to the markets into which we directly sell our products, we are utilizing our silicon nitride technology platform to expand our current penetration in the spinal fusion market through original equipment manufacturer (“OEM”) and private label partnerships. We also expect to do the same in other markets such as total hip and knee joint replacements, dental and sports medicine. We believe our biomaterial expertise, strong intellectual property and formulaic manufacturing process will allow us to transition currently available medical device products made of inferior biomaterials and manufacture them using silicon nitride and our technology platform to improve their characteristics.
We are also incorporating our silicon nitride technology into components for use in total hip and knee replacement product candidates that we plan on developing in collaboration with a strategic partner. We believe that our silicon nitride total hip and knee product candidates will provide competitive advantages over current products made with traditional biomaterials. We also believe our silicon nitride technology platform can be used for developing products in other markets and have developed prototypes for use in the dental, sports medicine and trauma markets. As a result of some of the key characteristics of our silicon nitride, we also believe our coating technology may be used to enhance our metal products as well as commercially available metal spinal fusion, joint replacement and other medical products.

16

We operate a 30,000 square foot manufacturing facility located at our corporate headquarters in Salt Lake City, Utah, and we are the only vertically integrated silicon nitride orthopedic medical device manufacturer in the world. We market and sell our products to surgeons and hospitals in the United States and select markets in Europe and South America through our established network of independent sales distributors who are managed by our experienced in-house sales and marketing management team. We have also started entering into OEM and private label relationships with third parties to further the commercialization of our silicon nitride technology platform beyond our own direct marketing and selling efforts.
September 2015 Offering
In September 2015, we entered into a Securities Purchase Agreement whereby we issued to certain investors 13,123,360 shares of common stock at a price of $0.381 per share for gross proceeds of $5.0 million before deducting placement agent fees and related offering expenses. Pursuant to the terms of the Securities Purchase Agreement the company also issued to the investors Series A Warrants, Series B Warrants, Series C Warrants and Series D Warrants. Each of the Series A Warrants, the Series B Warrants and the Series C Warrants are initially exercisable for 13,123,360 shares of common stock with an initial exercise price of $0.47 per share.
Shareholder approval is required for the issuance of the common shares underlying the Series B Warrants and Series C Warrants and the issuance of Series D Warrants. The Company obtained the requisite shareholder approval for the issuance at a Special Meeting of Stockholders held on November 3, 2015. The Series B and Series C Warrants have automatic exercise provisions that will be triggered if certain conditions are met, which include the attainment of requisite shareholder approval and the satisfaction of certain other equity trading conditions. In November, 2015, the automatic exercise provision of the Series B Warrants was triggered, pursuant to which the Company issued 49,862,877 shares of common stock at an exercise price of $0.10 per share and received gross proceeds of $5.0 million. The Company could receive up to a maximum of $5.0 million from the exercise of the Series C Warrants if they are exercised in full. Pursuant to the terms of the Series C Warrants and the exercise of the Series B Warrants, the exercise price of the Series C Warrants has been adjusted to $0.10 per share. If the Series C Warrants are exercised, the Series C exercise price will be the lesser of the current exercise price of $0.10 per share or 75% of the sum of the three lowest closing consolidated bid prices of the common stock during the five trading day period prior to the date on which payment of the exercise price is received by the Company. Pursuant to the terms of the Series C Warrants, the number of shares of common stock issuable upon the exercise of the Series C Warrants will be increased such that the gross proceeds from the exercise of the Series C Warrants will equal $5.0 million. The Series B Warrants and Series C Warrants expire on November 17, 2015 and December 30, 2015, respectively.
The number of Series A Warrants increase to match the number of shares of common stock issued upon the exercise of the Series B and Series C Warrants. The Series A Warrants have an exercise price adjustment provision that in the event the Company sells shares of any additional common stock or securities convertible into common stock prior to December 30, 2015, subject to certain exceptions, at a price per share less than the original exercise price of the warrant, the exercise price shall be adjusted to a price equal to the price paid per share for such additional common stock or securities. Pursuant to the terms of the Series A Warrants and as a result of the exercise of the Series B Warrants, the number of shares issuable upon the exercise of the Series A Warrants increased by 49,862,877 to 62,986,237 and the exercise price was adjusted to $0.10.
The Series A Warrants, Series B Warrant and Series C Warrants are considered to be liabilities and are marked to market at each reporting period until they are exercised or are no longer classified as liabilities. The Company estimated the fair value of these warrants to be $14.4 million. The Company recorded $4.9 million of the $5.0 million gross proceeds from the offering to derivative liabilities and $131,000 to equity and recorded a loss of $9.5 million, which was included in the change in fair value of derivative liabilities per the Condensed Consolidated Statements of Operations and Comprehensive Loss. Furthermore, all of the $821,000 of the September 2015 offering costs were expensed since the value of the warrants exceeded the gross proceeds.
The Company entered into a placement agent agreement in connection with the September 2015 Offering. As part of the placement agent agreement, the Company issued a warrant to the placement agent to purchase 656,168 shares of common stock at an exercise price of $0.47. The warrant was determined to be a liability and the estimated fair value of $157,000 was included in offering costs.

November 2014 Secondary Offering
On November 26, 2014, we completed a secondary offering, in which we sold and issued 11,441,646 units. Each unit was issued at a price of $1.14 and consisted of one share of common stock and one common stock warrant (“Secondary Offering Warrant”). We received proceeds of approximately $11.3 million, net of approximately $1.7 million in cash underwriting and other offering costs from the secondary offering. We issued an additional 1,716,246 Secondary Offering Warrants pursuant to the exercise of the underwriters’ over-allotment option.

17

The Secondary Offering Warrants were immediately exercisable after issuance into common shares at an exercise price of $1.48 and terminate on November 26, 2019. The Secondary Offering Warrants contain a cashless exercise provision whereby the holders may exercise warrants by paying the exercise price in cash or, in lieu of payment of the exercise price in cash, at any time 120 days after the November 26, 2014 issuance date, by electing to receive a cash payment from the Company equal to the Black Scholes Value (as defined below) of the number of shares the holder elects to exercise (the “Black Scholes Payment”); provided that we have discretion as to whether to deliver the Black Scholes Payment or, subject to meeting certain conditions, to deliver a number of shares of our common stock determined according to the following formula (the “Cashless Exercise”):
Total Shares = (A x B) / C
Where:
Total Shares is the number of shares of common stock to be issued upon a Cashless Exercise
A is the total number of shares with respect to which the warrant is then being exercised.
B is the Black Scholes Value (as defined below).
C is the closing bid price of our common stock as of two trading days prior to the time of such exercise.
As defined in the Secondary Offering Warrants, “Black Scholes Value” means the Black Scholes value of an option for one share of our common stock at the date of the applicable Black Scholes Payment or Cashless Exercise, which is calculated using the Black Scholes Option Pricing Model obtained from the “OV” function on Bloomberg utilizing (i) an underlying price per share equal to the closing bid price of the common stock as of trading day immediately preceding the date of issuance of the warrant, (ii) a risk-free interest rate corresponding to the U.S. Treasury rate for a period equal to the remaining term of the warrant as of the applicable Black Scholes Payment or Cashless Exercise, (iii) a strike price equal to the exercise price in effect at the time of the applicable Black Scholes Payment or Cashless Exercise, (iv) an expected volatility equal to 135% and (v) a remaining term of such option equal to five years (regardless of the actual remaining term of the warrant).
During the nine months ended September 30, 2015 , 13,047,372 of the Secondary Offering Warrants had been exercised via the cashless exercise provision resulting in the issuance of 38,202,840 shares of common stock. As of September 30, 2015 , there were 110,520 Secondary Offering Warrants outstanding.
Magna Notes
On April 2, 2015, we entered into an Amendment and Exchange Agreement (the “Amendment Agreement”) with Magna. The Amendment Agreement provides for the issuance by the Company to Magna of two new senior convertible notes, one with a maturity date in June 2016 and one with a maturity date in August 2016 (the "June Note", the "August Note," and collectively the “Exchange Convertible Notes”) in exchange for the Initial Convertible Note, the Additional Convertible Note and a warrant issued to Magna ("Magna Warrant") to purchase 568,889 shares of the Company's common stock at an exercise price of $4.65 . The exchange resulted in the cancellation of the Initial Convertible Note, Additional Convertible Note and Magna Warrant.
On June 19, 2015, the Company received written notice from Magna that an event of default had occurred with respect to the Exchange Convertible Notes and underlying agreements. On September 8, 2015, the Company entered into a Settlement and Waiver Agreement ("Settlement Agreement") with Magna. Pursuant to the Settlement Agreement, the Company paid Magna $2.5 million from the September 2015 Offering discussed above to redeem the entire $800,000 of outstanding principal amount and accrued interest of the June Note and to partially redeem $1.4 million principal amount of the August Note and any accrued interest. The Company agreed to pay an additional $1.25 million to partially redeem $1.1 million of the remaining principal amount of the August Note and any accrued interest if the Company receives gross proceeds of $5.0 million from the sale of equity securities and up to another $1.25 million to redeem in full the remaining August Note principal balance and interest if the Company receives up to an additional $5.0 million in gross proceeds. As part of the Settlement Agreement, Magna waived its event of default notice delivered to the Company on June 19, 2015 and its right to convert the August Note into shares of common stock.
The Settlement Agreement was accounted for as a debt extinguishment and the Company recorded a gain on extinguishment of debt of $2.4 million . Since the conversion features of the Exchange Convertible Notes were eliminated, the estimated fair value of the conversion features of $3.5 million was extinguished and included in the calculation of the gain on extinguishment of debt.
The outstanding principal amount of the remaining Magna August Note was $2.1 million at September 30, 2015. The Magna August Note matures on August 11, 2016 , and accrues interest at an annual rate of 6.0% .

Hercules Term Loan
On June 30, 2014, we entered into a Loan and Security Agreement with Hercules Technology Capital, Inc. ("Hercules Technology" or “Hercules”) in connection with the Hercules Term Loan.  The Hercules Term Loan provided us with a $20 million term loan. The Hercules Term Loan matures on January 1, 2018. The Hercules Term Loan also includes a non-refundable final payment fee of $1.7 million.  The final payment fee is being accrued and recorded to interest expense over the life of the loan.
The Hercules Term Loan bears interest at the rate of the greater of either (i) the prime rate plus 7.7%, and (ii) 10.95%.  Interest accrues from the closing date of the loan and interest payments are due monthly. Principal payments are required commencing August 1, 2015 and are to be made in 30 equal installments of approximately $700,000, with the remainder due at maturity. Our obligations to Hercules are secured by a first priority security interest in substantially all of our assets, including intellectual property. The Hercules Term Loan contains certain covenants related to restrictions on payments to certain affiliates and financial reporting requirements.
On June 30, 2015, we received written notice from Hercules that an event of default has occurred with respect to the Hercules Term Loan. On September 8, 2015, we entered into a Consent and First Amendment to Loan and Security Agreement (the “Amendment”) with Hercules. The Amendment amends certain terms of the Hercules Loan and Security Agreement and grants to us certain consents relating to the Settlement Agreement with Magna discussed above. The Amendment provides that if we prepay the Hercules Term Loan, we must pay a prepayment charge of 1.5% of the amount being prepaid until September 8, 2016 and 0.75% thereafter. The Amendment also increased the fee we must pay to Hercules upon prepayment of the loan or upon maturity of the loan from $1.5 million to $1.7 million. Further, the annual interest rate on the loan will increase by 1.5% if we don't receive gross proceeds of at least $10.0 million from the exercise of the Series B and Series C Warrants discussed above. As part of the Amendment, Hercules waived and released its event of default notice sent on June 30, 2015. Additionally, the Amendment reduces our obligation to maintain cash and cash equivalents of not less than $9.0 million to an amount that varies based on the loan amount. The minimum cash requirement is reduced by $500,000 for every $1.0 million paid in principal to a minimum of $2.5 million. The minimum cash and cash equivalents balance required to maintain compliance with the minimum liquidity covenant at September 30, 2015 was $8.5 million. Although we were in compliance with the liquidity covenant at September 30, 2015, we anticipate we will be non-compliant with the liquidity covenant during the fourth quarter of 2015 if additional financing is not obtained, and have therefore classified the entire obligation as a current liability. As part of the Amendment, the warrant held by Hercules was modified to increase the number of underlying shares to 1,548,387 and decrease the exercise price to $0.47, subject to adjustment.
Components of our Results of Operations
We manage our business within one reportable segment, which is consistent with how our management reviews our business, makes investment and resource allocation decisions and assesses operating performance.
Product Revenue
We derive our product revenue primarily from the sale of spinal fusion devices and related products used in the treatment of spine disorders. Our product revenue is generated from sales to three types of customers: (1) surgeons and hospitals; (2) stocking distributors; and (3) private label customers. Most of our products are sold on a consignment basis through a network of independent sales distributors; however, we also sell our products to independent stocking distributors. Product revenue is recognized when all four of the following criteria are met: (1) persuasive evidence that an arrangement exists; (2) delivery of the products has occurred; (3) the selling price of the product is fixed or determinable; and (4) collectability is reasonably assured. We generate the majority of our revenue from the sale of inventory that is consigned to independent sales distributors that sell our products to surgeons and hospitals. For these products, we recognize revenue at the time we are notified the product has been used or implanted and all other revenue recognition criteria have been met. For all other transactions, we recognize revenue when title and risk of loss transfer to the stocking distributor, and all other revenue recognition criteria have been met. We generally recognize revenue from sales to stocking distributors at the time the product is shipped to the distributor. Stocking distributors, who sell the products to their customers, take title to the products and assume all risks of ownership at time of shipment. Our stocking distributors are obligated to pay within specified terms regardless of when, if ever, they sell the products. Our policy is to classify shipping and handling costs billed to customers as an offset to total shipping expense in the statement of operations, primarily within sales and marketing. In general, our customers do not have any rights of return or exchange.
We believe our product revenue from the sale of our silicon nitride based products will increase due to our sales and marketing efforts and as we introduce new silicon nitride based products into the market and product revenue from the sale of our non-

19

silicon nitride products to remain flat. We expect that our product revenue will continue to be primarily attributable to sales of our products in the United States.
Cost of Revenue
The expenses that are included in cost of revenue include all direct product costs if we obtained the product from third-party manufacturers and our in-house manufacturing costs for the products we manufacture. We obtain our non-silicon nitride products, including our metal and orthobiologic products, from third-party manufacturers, while we currently manufacture the majority of our silicon-nitride products in-house.
Specific provisions for excess or obsolete inventory and, beginning in 2013, the excise tax on the sale of medical devices in the United States, are also included in cost of revenue. In addition, we pay royalties attributable to the sale of specific products to some of our surgeon advisors that assisted us in the design, regulatory clearance or commercialization of a particular product, and these payments are recorded as cost of revenue.
Gross Profit
Our gross profit measures our product revenue relative to our cost of revenue. We expect our gross profit to decrease as we expand the penetration of our silicon nitride technology platform through OEM and private label partnerships.
Research and Development Expenses
Our net research and development costs are expensed as incurred. Research and development costs consist of engineering, product development, clinical trials, test-part manufacturing, testing, developing and validating the manufacturing process, manufacturing, facility and regulatory-related costs. Research and development expenses also include employee compensation, employee and non-employee stock-based compensation, supplies and materials, consultant services, and travel and facilities expenses related to research activities. To the extent that certain research and development expenses are directly related to our manufactured products, such expenses and related overhead costs are allocated to inventory.
We expect to incur additional research and development costs as we continue to develop new spinal fusion products, our product candidates for total joint replacements, such as our total hip replacement product candidate, and our silicon nitride-coated metals which may increase our total research and development expenses.
Sales and Marketing Expenses
Sales and marketing expenses consist of salaries, benefits and other related costs, including stock-based compensation, for personnel employed in sales, marketing, medical education and training. In addition, our sales and marketing expenses include commissions and bonuses, generally based on a percentage of sales, to our sales managers and independent sales distributors. We provide our products in kits or banks that consist of a range of device sizes and separate instruments sets necessary to perform the surgical procedure. We generally consign our instruments to our distributors or our hospital customers that purchase the device used in spinal fusion surgery. Our sales and marketing expenses include depreciation of the surgical instruments.
We expect our sales and marketing expenses will remain flat or slightly decline due to the cost saving measures implemented during the first quarter. Additionally, we expect our commissions to increase in absolute terms over time but remain approximately the same or decrease as a percentage of product revenue.
General and Administrative Expenses
General and administrative expenses primarily consist of salaries, benefits and other related costs, including stock-based compensation, for certain members of our executive team and other personnel employed in finance, legal, compliance, administrative, information technology, customer service, executive and human resource departments. General and administrative expenses include allocated facility expenses, related travel expenses and professional fees for accounting and legal services.
We expect our general and administrative expenses to decrease as a result of the restructuring and cost saving measures implemented during the first quarter of 2015.

For the three months ended September 30, 2015 , total product revenue decreased $1.2 million , or 19% , as compared to the same period in 2014 . The decrease was primarily due to decreased sales of our non-silicon nitride products, which decreased by $0.9 million , or 27% , for the three months ended September 30, 2015 as compared to the same period in 2014 . This decline was primarily due to lower metals sales as a result of a decline in the level of activity for a few key surgeons and our continued focus and investment in sales and marketing efforts of our silicon nitride products. Silicon nitride sales decreased by $0.3 million , or 10% , as compared to the same period in 2014 .  This decline was primarily attributable to the loss of a few surgeons during the year and consequences from our restructuring. This was partially offset by the addition of new surgeons, as well as international and private label sales.
For the nine months ended September 30, 2015 , total product revenue decreased $3.3 million , or 18% , as compared to the same period in 2014 . The decrease was primarily due to decreased sales of our non-silicon nitride products, which decreased by $2.8 million , or 29% , for the nine months ended September 30, 2015 as compared to the same period in 2014 . This decline was primarily due to lower metals sales as a result of a decline in the level of activity for a few key surgeons and our continued focus and investment in sales and marketing efforts of our silicon nitride products. Silicon nitride sales decreased by $0.5 million , or 6% , as compared to the same period 2014 .  This decline was primarily attributable to the loss of a few surgeons during the year and consequences from our restructuring. This was partially offset by the addition of new surgeons, as well as international and private label sales.

International revenue increased during the three months ended September 30, 2015 as compared to the same periods in 2014 , primarily as a result of having received regulatory approval to begin selling our silicon nitride products in Brazil.
Cost of Revenue and Gross Profit
For the three months ended September 30, 2015 , our cost of revenue decreased $0.3 million , or 15% , as compared to the same period in 2014 . The decrease in cost of revenue was primarily a result of reduced sales for the three months ended September 30, 2015 , as compared to the same period in 2014. Although we have reduced our product costs through production efficiencies and lower overhead costs, our gross profit as a percentage of product revenue decreased by 2% to 66% for the three months ended September 30, 2015 from 68% for the same period in 2014 as a result of revenue recognized from private label sales and international sales during 2015, which has lower gross margins due to lower selling prices.
For the nine months ended September 30, 2015 , our cost of revenue decreased $0.7 million , or 13% , as compared to the same period in 2014 . The decrease in cost of revenue was primarily a result of reduced sales for the nine months ended September 30, 2015 , as compared to the same period in 2014. Although we have reduced our product costs through production efficiencies and lower overhead costs, our gross profit as a percentage of product revenue decreased by 3% to 68% for the nine months ended September 30, 2015 from 71% for the same period in 2014 primarily as a result of revenue recognized from private label sales during 2015, which has lower gross margins due to lower selling prices.
Research and Development Expenses
For the three months ended September 30, 2015 , research and development expenses decreased $0.3 million , or 15% , as compared to the same period in 2014 . This decrease was primarily due to a $0.5 million decrease in stock-based compensation and $0.7 million decrease in personnel related and other development costs. This was offset by an increase in operating expenses that could not be allocated to inventory due to lower production levels of our Valeo products in 2015 as compared to the same period in 2014 . In 2014, as a result of the ramp-up phase for our second generation Valeo products, these overhead costs had previously been allocated to inventory.
For the nine months ended September 30, 2015 , research and development expenses decreased $0.5 million , or 9% , as compared to the same period in 2014 . This decrease was primarily due to a $1.1 million decrease in stock compensation and $2.3 million decrease in personnel related and other development costs, which was offset by an increase in operating expenses that could not be allocated to inventory due to lower production levels of our Valeo products during the nine months ended September 30, 2015 as compared to the same period in 2014. In 2014, as a result of the ramp-up phase for our second generation Valeo products, these overhead costs had previously been allocated to inventory.
General and Administrative Expenses
For the three months ended September 30, 2015 , general and administrative expenses decreased $1.5 million , or 51% , as compared to the same period in 2014 . This decrease was primarily due to a $0.7 million decrease in stock-based compensation and $0.8 million decrease in personnel related costs resulting from the restructure in the first quarter of 2015.
For the nine months ended September 30, 2015 , general and administrative expenses decreased $7.5 million , or 61% , as compared to the same period in 2014 . This decrease was primarily due to a $5.8 million decrease in stock-based compensation and $0.9 million decrease in personnel related costs and $0.7 million decrease in other operating expenses as we have reduced operating costs in 2015.

Sales and Marketing Expenses
For the three months ended September 30, 2015 , sales and marketing expenses decreased $1.9 million , or 40% , as compared to the same period in 2014 .  This decrease was primarily due to a $0.5 million decrease in stock-based compensation, a $0.6 million decrease in commissions due to lower sales, and a $0.8 million decrease in personnel related costs, consulting, and other operating expenses as we have reduced operating costs in 2015.
For the nine months ended September 30, 2015 , sales and marketing expenses decreased $5.5 million , or 37% , as compared to the same period in 2014 .  This decrease was primarily due to a $2.1 million decrease in stock compensation, a $1.6 million decrease in commissions due to lower sales, and a $1.8 million decrease in personnel related costs, travel, consulting and other operating expenses as we have reduced operating costs in 2015.
Other Income (Expense), Net
For the three months ended September 30, 2015 , other expense increased $8.0 million as compared to the same period in 2014 . This increase was primarily due to offering costs of $0.8 million and an increase of $9.7 million from the change in fair value of derivative liabilities primarily due to the issuance of warrants in the September 2015 Offering. These increases were partially offset by a $2.4 million gain on the extinguishment of the Magna debt in September 2015.
For the nine months ended September 30, 2015 , other expense increased $9.5 million as compared to the same period in 2014 . This increase was primarily due to offering costs of $0.8 million, an increase of $9.7 million from the change in fair value of derivative liabilities primarily due to the issuance of warrants in the September 2015 Offering, a $1.3 million loss on extinguishment of derivative liabilities during 2015 when certain warrants were exercised, and a $1.2 million increase in interest expense from additional debt incurred during the second quarter of 2014. These increases were partially offset by a $2.4 million gain on the extinguishment of debt during the nine months ended September 30, 2015 as compared to a $1.6 million loss on extinguishment of debt for the same period in 2014.
Liquidity and Capital Resources
For the nine months ended September 30, 2015 and 2014, we incurred a net loss of $21.4 million and $22.9 million , respectively, and used cash in operations of $7.1 million and $11.4 million, respectively. We have an accumulated deficit of $194.1 million as of September 30, 2015 . To date, our operations have been principally financed from proceeds from the issuance of convertible preferred stock and common stock, convertible debt and bank debt and, to a lesser extent, cash generated from product sales. As of September 30, 2015 , we had approximately $11.3 million in cash and cash equivalents.
We will need to from time-to-time seek additional financing through the issuance of common stock and/or debt, to satisfy our debt obligations and financial covenants, meet our working capital requirements, make continued investment in research and development and make capital expenditures needed for us to maintain and expand our business. We anticipate we will need to obtain additional funding in the fourth quarter of 2015 to maintain compliance with the financial and liquidity covenants related to the Hercules Term Loan into 2016. As discussed previously, the Company received gross proceeds of $5.0 million in November 2015 from the exercise of the Series B Warrants and could potentially raise up to an additional $5.0 million during the fourth quarter of 2015 from the exercise of the Series C Warrants issued in September 2015. However, if the Series C Warrants are not exercised and the Company is unable to access additional funds prior to becoming non-compliant with the financial and liquidity covenants related to the Hercules Term Loan, the entire remaining balance of the debt under the Hercules Term Loan could become immediately due and payable at the option of Hercules Technology. We may not be able to obtain additional financing on terms favorable to us, if at all. It is also possible that we may allocate significant amounts of capital toward solutions or technologies for which market demand is lower than anticipated and, as a result, abandon such efforts. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, or if we expend capital on projects that are not successful, our ability to continue to support our business growth and to respond to business challenges could be significantly limited, or we may even have to scale back our operations. If we raise additional funds through further issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock.
Going Concern
Our ability to access capital when needed is not assured and, if not achieved on a timely basis, will materially harm our business, financial condition and results of operations. These uncertainties create substantial doubt about our ability to continue as a going concern. Our independent registered public accounting firm included an explanatory paragraph regarding substantial doubt about our ability to continue as a going concern in their report on our annual financial statements for the fiscal year ended December 31, 2014. The financial information and statements throughout this quarterly report have been prepared on a basis which assumes that we will continue as a going concern, which contemplates the realization of assets and the satisfaction

23

of liabilities and commitments in the normal course of business. This financial information and statements do not include any adjustments that may result from the outcome of this uncertainty.

Net Cash Used in Operating Activities
Net cash used in operating activities was $ 7.1 million during the nine months ended September 30, 2015 , compared to $11.4 million for the same period in 2014 , a decrease of $ 4.4 million . The decrease in cash used in operating activities during 2015 was primarily attributable to lower production rates resulting in a $5.2 million decrease in inventories and lower operating expenses, which were partially offset by $0.9 million of severance and benefits for terminated employees paid during the nine months ended September 30, 2015 .
Net Cash Used in Investing Activities
Net cash used in investing activities was $0.5 million during the nine months ended September 30, 2015 , compared to $1.6 million used in investing activities during the same period in 2014 , a decrease of $1.1 million. The decrease in net cash used in investing activities during 2015 was primarily attributable to decreased purchases of property and equipment of $1.5 million and a decrease in restricted cash of $0.4 million during 2015 as compared to 2014 .
Net Cash Provided by Financing Activities
Net cash provided by financing activities was $ 0.6 million during the nine months ended September 30, 2015 , compared to $ 21.1 million provided during the same period in 2014 , a decrease of $20.5 million. The cash provided by financing activities in 2015 was primarily attributable to receiving $4.3 million in net proceeds from the issuance of common stock and warrants which was offset by long-term debt payments of $3.7 million. The cash provided by financing activities in 2014 was primarily attributable to receiving $15.4 million in net proceeds from the issuance of common stock in our IPO. Additionally, long-term debt increased by $5.8 million due to the debt refinancing in June and August 2014.
Indebtedness
For a description of our material indebtedness see information above under the headings “ Hercules Term Loan ” and “ Magna Notes.”
Off-Balance Sheet Arrangements
We do not have any off-balance sheet arrangements, as defined in Item 303(a)(4) of Regulation S-K.
Critical Accounting Policies and Estimates
A summary of our significant accounting policies and estimates is discussed in Management’s Discussion and Analysis of Financial Condition and Results of Operations and in Note 1 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2014. There have been no material changes to those policies during the nine months ended September 30, 2015 . The preparation of the financial statements in accordance with U.S. generally accepted accounting principles requires us to make judgments, estimates and assumptions regarding uncertainties that affect the reported amounts of assets and liabilities. Significant areas of uncertainty that require judgments, estimates and assumptions include the accounting for income taxes and other contingencies as well as valuation of derivative liabilities, asset impairment and collectability of accounts receivable. We use historical and other information that we consider to be relevant to make these

24

judgments and estimates. However, actual results may differ from those estimates and assumptions that are used to prepare our financial statements.
New Accounting Pronouncements
See discussion under Note 1, Organization and Summary of Significant Accounting Policies, to the Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q, for information on new accounting pronouncements.
ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Not applicable.
ITEM 4. CONTROLS AND PROCEDURES
This Report includes the certifications of our Chief Executive Officer and Principal Accounting Officer required by Rule 13a-14 of the Securities Exchange Act of 1934 (the “Exchange Act”). See Exhibits 31.1 and 31.2. This Item 4 includes information concerning the controls and control evaluations referred to in those certifications.
Evaluation of Disclosure Controls and Procedures
Our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in rules and forms adopted by the Securities and Exchange Commission, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and our Principal Accounting Officer, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.
In connection with the preparation of this report, our management, under the supervision and with the participation of our Chief Executive Officer and our Principal Accounting Officer, evaluated the effectiveness of our disclosure controls and procedures. Based on that evaluation, our Chief Executive Officer and Principal Accounting Officer have concluded that our disclosure controls and procedures were effective as of September 30, 2015 .
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting that occurred during the third quarter of 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
PART II
ITEM 1. LEGAL PROCEEDINGS
We are not aware of any pending or threatened legal proceeding against us that could have a material adverse effect on our business, operating results or financial condition. The medical device industry is characterized by frequent claims and litigation, including claims regarding patent and other intellectual property rights as well as improper hiring practices. As a result, we may be involved in various additional legal proceedings from time to time.
ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS
Unregistered sales of equity securities during the quarterly period ended September 30, 2015 were previously reported by the Company in a Form 8-K dated September 8, 2015 and filed with the Securities and Exchange Commission on that same date.

On October 19, 2015, the company issued 240,000 shares of our common stock to a service provider for services with respect to certain corporate development activities. The sales and issuances of these securities were exempt from registration under the Securities Act in reliance upon Section 4(2) of the Securities Act, as transactions by an issuer not involving any public offering. The recipient represented its intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and an appropriate legend was placed upon the stock certificate issued in this transaction.  No underwriter was involved in this transaction.
