Unaudited Interim Financial Information | |
The accompanying unaudited interim consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and regulations of the Securities and Exchange Commission (the SEC) regarding interim financial reporting. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2013 included in our prospectus dated June 12, 2014 and filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on June 16, 2014 (the Prospectus). | |
In the opinion of the Company’s management, the unaudited interim consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments that are of a normal recurring nature and necessary for the fair statement of the Company’s financial position as of September 30, 2014 and the results of its operations for the three months and nine months ended September 30, 2014 and 2013 and the cash flows for the nine month period then ended. The Company has evaluated events through the date of this filing. | |
The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results to be expected for the year ending December 31, 2014 or any other period. | |
There have been no changes to our significant accounting policies described in the Prospectus that have had a material impact on our consolidated financial statements and notes thereto. All intercompany balances and transactions have been eliminated in consolidation. | |
Reclassification | |
The December 31, 2013 balance sheet reflects a $0.2 million reclassification of the Company’s sales returns reserve from a component of accrued expenses to a reduction of accounts receivable, a $0.1 million reclassification of other assets to prepaid expenses and other current assets and a reclassification of $0.1 million of other long term liabilities to other current liabilities to conform to the current period’s presentation.

Initial Public Offering | ' |
(2) Initial Public Offering | |
On June 18, 2014, the Company completed an initial public offering (an IPO) of 7,500,000 shares of its common stock at a public offering price of $11.00 per share. The Company received net proceeds of $74.7 million after deducting underwriting discounts and commissions of $4.3 million and other offering expenses of approximately $3.5 million. Upon the closing of the offering, all of the Company’s then-outstanding (i) warrants to purchase Series C preferred stock, (the “Series C warrants”) were subject to an automatic net cashless exercise, (ii) convertible preferred stock (including the shares of Series C preferred stock issued upon the automatic net cashless exercise of Series C warrants) automatically converted into 115,982 shares of common stock, and (iii) Convertible Notes (see note 9) and Senior Convertible Notes (see note 8) automatically converted into 15,319,034 shares of common stock. | |
Prior to the closing of the offering, the Company completed a 1-for-824.7412544 reverse stock split of its common stock. All common shares and related per share amounts in the financial statements and notes have been adjusted retroactively to reflect the reverse stock split. | |
Upon the closing of the IPO, the Company amended and restated its certificate of incorporation. The total number of shares of all classes of stock which the Company has the authority to issue is 130,000,000 shares, consisting of 125,000,000 shares of common stock, par value $0.00001 per share (the common stock) and 5,000,000 shares of preferred stock, par value $0.00001 per share (the preferred stock). | |
2014 Employee, Director and Consultant Equity Incentive Plan | |
Upon completion of the IPO, the Company adopted the 2014 Employee, Director and Consultant Equity Incentive Plan (the 2014 Equity Plan). Under the 2014 Equity Plan, the Company may grant incentive stock options, non-qualified stock options, restricted stock, unrestricted stock and other stock-based awards. Stock options under the plan are to be granted with an exercise price not less than the fair market value of the Company’s common stock at the date of grant. |

(3) Significant Accounting Policies | |||||||||||||||||
Use of Estimates | |||||||||||||||||
The preparation of the consolidated financial statements requires the Company to make a number of estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include allowances for doubtful accounts, inventory valuation, the carrying amount of property and equipment, fair value of debt and capital stock, stock-based compensation and deferred income taxes. The Company evaluates its estimates and assumptions on an on-going basis using historical experience and other factors, including the current economic environment, which it believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity markets and declines in business investment increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. | |||||||||||||||||
Cash | |||||||||||||||||
Cash balances are maintained with a major financial institution in North America. Deposits with this financial institution exceed the amount of insurance provided on such deposits. | |||||||||||||||||
Fair Value of Financial Instruments | |||||||||||||||||
Fair value is an exit price that represents the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. Accordingly, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company discloses the manner in which fair value is determined for assets and liabilities based on a three-tiered fair value hierarchy. The hierarchy ranks the quality and reliability of the information used to determine the fair values. The three levels of inputs described in the standard are: | |||||||||||||||||
Level 1: | Quoted prices in active markets for identical assets or liabilities. | ||||||||||||||||
Level 2: | Observable inputs, other than Level 1 prices, for the assets or liabilities, either directly or indirectly, for substantially the full term of the assets or liabilities. | ||||||||||||||||
Level 3: | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | ||||||||||||||||
Under the Fair Value Option Subsections of Financial Accounting Standards Board (FASB) ASC Subtopic 825-10, Financial Instruments — Overall, the Company has the irrevocable option to report most financial assets and financial liabilities at fair value on an instrument by instrument basis, with changes in fair value reported in earnings each reporting period. As a result of electing this option, the Company had recorded its Subordinated Notes, Senior Convertible Notes and Convertible Notes at fair value in order to measure these liabilities at amounts that more accurately reflect the economics of these instruments (see notes 7, 8 and 9). | |||||||||||||||||
During the nine months ended September 30, 2014 and at December 31, 2013, the Company valued its Subordinated Notes, Senior Convertible Notes and Convertible Notes utilizing Level 3 inputs. | |||||||||||||||||
Stock-based Compensation | |||||||||||||||||
Stock-based compensation cost is measured at the grant date based on the fair value of the award. Expense is recognized on a straight-line basis over the requisite service period for all awards with service conditions. For performance-based awards, the grant date fair value is recognized as expense when the condition is probable of being achieved, and then on a graded basis over the requisite service period. The Company uses the Black-Scholes option-pricing model to determine the fair value of service-based awards, which requires a number of complex and subjective assumptions including fair value of the underlying security, the expected volatility of the underlying security, a risk-free interest rate, the expected term of the option and the forfeiture rate. For performance-based stock options issued during the year ended December 31, 2013, the Company used a Monte Carlo simulation model to estimate the number of options the Company expected to remain outstanding and eligible for vesting upon completion of an IPO. The simulation model was based on a number of complex assumptions including the terms of the performance condition, the expected value of the Company’s common stock at the time of its IPO, the expected time from the date of grant to its IPO, and expected volatility. The compensation cost of these performance-based options was determined by multiplying the Black-Scholes estimate of grant date fair value by the percentage of options expected to remain outstanding and eligible for vesting upon completion of the Company’s IPO. As a result of the closing of the IPO, the Company recorded $5.6 million of stock-based compensation related to these performance-based awards during the nine months ended September 30, 2014. | |||||||||||||||||
Upon the completion of the IPO, the Company issued 61,816 shares of restricted common stock with an aggregate value at issuance of approximately $0.7 million to its non-employee directors. In September 2014 the Company issued 318,517 restricted common stock units (RSU) and non-qualified stock options (NSO) to purchase 934,018 shares of common stock to employees under the 2014 Equity Plan. The RSUs and NSOs will vest over a four year period for certain employees and over a three year period for other employees. | |||||||||||||||||
Earnings per Share | |||||||||||||||||
Prior to the IPO, net income (loss) per common share was calculated using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for the holders of the Company’s common shares and participating securities. Prior to their conversion to common stock at the time of the Company’s IPO, the Company’s Series A preferred stock, Series B preferred stock and Series C preferred stock warrants contained participation rights in any dividend to be paid by the Company to holders of its common shares and were deemed to be participating securities. Net income (loss) available to common shareholders and participating securities was allocated to each share on an as-if-converted basis as if all of the earnings for the period had been distributed. The participating securities did not include a contractual obligation to share in losses of the Company and were not included in the calculation of net loss per share in the periods that have a net loss. | |||||||||||||||||
Diluted net income (loss) per share is computed using the more dilutive of (a) the two-class method, or (b) the if-converted method. The Company allocates net income (loss) first to preferred stockholders and holders of warrants to purchase preferred stock based on dividend rights and then to common, preferred stockholders and preferred warrant holders based on ownership interests. The weighted-average number of common shares included in the computation of diluted net income (loss) gives effect to all potentially dilutive common equivalent shares, including outstanding stock options and warrants. Common equivalent shares are excluded from the computation of diluted net income (loss) per share if their effect is antidilutive. | |||||||||||||||||
Subsequent to the IPO, the Company calculates net income (loss) per common share based on the weighted-average number of common shares outstanding during each period. Potential common stock equivalents are determined using the treasury stock method. The weighted-average number of common shares included in the computation of diluted net income (loss) gives effect to all potentially dilutive common equivalent shares, including outstanding stock options, restricted common stock units and warrants. Common equivalent shares are excluded from the computation of diluted net income (loss) per share if their effect is antidilutive. | |||||||||||||||||
Segments | |||||||||||||||||
Operating segments are identified as components of an enterprise about which discrete financial information is available for evaluation by the chief operating decision maker when making decisions on how to allocate resources and assess performance. The Company’s chief operating decision maker is the Chief Executive Officer. The Company’s chief operating decision maker reviews consolidated operating results to make decisions about allocating resources and assessing performance for the entire Company. The Company views its operations and manages its business as one operating segment. | |||||||||||||||||

Recently Issued Accounting Standards | |||||||||||||||||
In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers. The standard will eliminate the transaction- and industry-specific revenue recognition guidance under current U.S. GAAP and replace it with a principle based approach for determining revenue recognition. Public entities are required to apply the revenue recognition standard for annual reporting period beginning on or after December 15, 2016, including interim periods within that annual reporting period. Early application is not permitted. The Company has not yet selected a transition method and is evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures. | |||||||||||||||||
In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements — Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The standard requires an entity’s management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Public entities are required to apply standards for annual reporting periods ending after December 15, 2016, and interim periods thereafter. Early application is permitted. The Company is evaluating the impact of this standard on its consolidated financial statements. | |||||||||||||||||
From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. |

As of December 31, 2013, Subordinated Notes of $17.3 million were classified as a current liability. In June 2014, the Company used a portion of the net proceeds from the initial public offering discussed in note 2 to repay $18.8 million of the original principal balance and accrued interest on the Subordinated Notes. As of June 20, 2014, all obligations under the Subordinated Notes had been paid in full. | |||||
The Company elected the fair value option for the Subordinated Notes and recorded the instrument at fair value. The fair value of the Subordinated Notes was determined by analysis of the amount to be paid on the notes at the occurrence of certain events in which the Subordinated Notes would be repaid to the noteholders in cash. The probability weighted discounted cash flow analysis utilized assumptions related to the probability of the occurrence of each of the various events and appropriate discount rates for each of the scenarios. | |||||
At September 30, 2013, the valuations were calculated at an implied discount of approximately 20% and were weighted as follows: repayment prior to maturity on June 30, 2014, 20%; and repayment at maturity on September 30, 2014, 80%. There would not be a material difference if the weightings were increased or decreased by 10%. At September 30, 2013, the aggregate fair value of the Subordinated Notes was determined to be $16.5 million, with an aggregate unpaid principal balance totaling $14.4 million. | |||||

Effective March 28, 2013, the Company entered into a Note and Warrant Purchase Agreement (March 2013 NPA) authorizing the issuance of $22.5 million of Senior Subordinated Convertible Notes (the March 2013 Investor Notes) and Senior Subordinated Arcapita Notes (the March 2013 Arcapita Notes) (collectively, the Senior Convertible Notes). At each closing under the March 2013 NPA, the Company issued warrants to purchase shares of a newly created Series C Preferred Stock (the Series C) based on the principal balance of Senior Convertible Notes issued to each purchaser. The Company determined that the Series C warrants, which were subject to net share settlement, were equity classified. Collectively, the warrants issued pursuant to the March 2013 NPA were exercisable for Series C shares equal to 85.7% of the then outstanding capital stock of the Company on a fully diluted basis. The warrants had an exercise price of $0.0001 per share, were immediately exercisable and were scheduled to expire by their terms on March 28, 2023. | |||||||||||||||||
Pursuant to side letter agreements, in March and May 2013, holders of $7.5 million of Convertible Notes (see note 9) issued in November 2012 and January 2013 (the Initial Notes) exchanged their original principal balance for an equivalent principal amount of Senior Convertible Notes (the Exchanged Notes) and a pro-rata share of Series C warrants issued under the March 2013 NPA. The Company accounted for the warrants as a debt issuance cost and recorded an immediate charge for the fair value of the Series C warrants totaling $5.4 million in other income (expense). Pursuant to the exchange, the holders of the Exchanged Notes received notes senior in preference to the Initial Notes and with an extended maturity date of March 28, 2016. | |||||||||||||||||
Given that the terms of the Exchanged Notes were substantially different than the terms of the Initial Notes, the exchange was accounted for as an extinguishment of debt. Upon the exchange, the Company recognized a loss totaling $5.7 million for the nine month period ended September 30, 2013. This loss represents the difference between (i) the fair value of the Exchanged Notes at reissuance and the fair value of Series C warrants, and (ii) the carrying value of the Initial Notes. The Company elected to account for all of the issuances of its Senior Convertible Notes and various embedded derivatives in accordance with ASC Topic 825-10, Fair Value Option for Financial Liabilities, whereby the Company initially and subsequently measured this financial instrument in its entirety at fair value, with the changes in fair value recorded each reporting period in interest expense (income). | |||||||||||||||||
In March and May 2013, the Company issued an additional $15.0 million of Senior Convertible Notes. The noteholders received a pro-rata share of Series C warrants for their participation in these financings. The Company accounted for the warrant issuances as a debt issuance cost and recorded an immediate charge for the fair value of the Series C warrants. For the three and nine months ended September 30, 2013, the Company recorded $0.0 million and $10.7 million, respectively, as a charge to interest expense related to the warrants (see note 11). | |||||||||||||||||
In conjunction with the March 2013 NPA, the Company incurred $0.9 million of debt issuance costs during the nine months ended September 30, 2013. These debt issuance costs were allocated between the debt and equity instruments related to the transaction. Of the total debt issuance costs, $0.6 million was allocated to the Senior Convertible Notes and recorded through interest expense, while the remaining $0.3 million was allocated to the Series C warrants with an offset for additional paid-in capital. | |||||||||||||||||
Upon the closing of the Company’s IPO discussed in note 2, the outstanding principal and accrued interest on the Senior Convertible Notes were marked to an aggregate fair value of $39.5 million and automatically converted into 3,591,604 shares of common stock equal to the unpaid principal amount of the Senior Convertible Notes and accrued interest as of June 18, 2014 divided by the Conversion Price, which was 62.5% of the initial public offering price of $11.00 per share. In addition, all outstanding Series C warrants were automatically net exercised, which, together with the then outstanding shares of Series C preferred stock, converted into 104,734 shares of common stock upon the closing of the Company’s IPO. | |||||||||||||||||

The change in the fair values of the Senior Convertible Notes during the nine months ended September 30, 2014 and 2013 was determined by utilizing probability weighted discounted cash flow analyses, which took into consideration market and general economic events, as well as the Company’s financial results and other data available as of September 30, 2014 and 2013. These analyses determined the amount to be paid on the Senior Convertible Notes in either cash or shares at the occurrence of certain events in which the Senior Convertible Notes would be converted into shares of the Company’s common stock or would be repaid in cash. The probability weighted discounted cash flow analyses utilized assumptions related to the probability of the occurrence of each of the various events and appropriate discount rates for each of the scenarios as follows: | |||||||||||||||||

Commencing in June 2011 and concluding in January 2013, the Company issued a total of $69.9 million of 8% subordinated convertible notes (the Investor Notes) to new and existing investors. The Investor Notes had original maturity dates of June 1, 2014, June 14, 2014 and December 6, 2014, depending on their date of issuance. Commencing in December 2011 and concluding in September 2012, the Company issued a total of $3.5 million of noninterest bearing convertible notes to an existing investor (the Arcapita Notes, and together with the Investor Notes, the Convertible Notes). The Arcapita Notes were originally set to mature on December 6, 2014. Net proceeds from the Convertible Notes were used to fund the completion of the Company’s second production line at the East Providence facility, to begin the construction of a third production line at the East Providence facility and to fund the Company’s operating cash requirements. | |||||||||||||||||
In conjunction with the execution of the March 2013 NPA (see note 8) on March 28, 2013, the holders of all but approximately $0.3 million of the original principal amount of the Convertible Notes agreed to extend the original maturity date of their notes by two years. Given that the term of the Convertible Notes, as amended, differed substantially from the original term, the amendment was accounted for as an extinguishment of debt. On March 28, 2013, the Company recognized a gain on extinguishment totaling $8.9 million, which represents the difference between (i) the fair value of the Convertible Notes at reissuance, and (ii) the fair value of the Convertible Notes just prior to the amendment. | |||||||||||||||||
The Company elected to record the Convertible Notes at fair value upon issuance. The aggregate fair value of the Convertible Notes was $91.9 million as of December 31, 2013. | |||||||||||||||||
Upon the closing of the Company’s IPO discussed in note 2, the outstanding principal and accrued interest on the Convertible Notes were marked to an aggregate fair value of $129.0 million and automatically converted into 11,727,430 shares of common stock equal to the unpaid principal amount of the Convertible Notes and accrued interest divided by the Conversion Price, which was 62.5% of the initial public offering price of $11.00 per share. | |||||||||||||||||

(10) Revolving Line of Credit | |
In March 2011, the Company entered into a $10.0 million revolving credit facility with Silicon Valley Bank. This facility has been amended at various dates through 2014. | |
On September 3, 2014, the Company amended its line of credit agreement to extend the maturity date of the facility to August 31, 2016 and increase the maximum amount the Company is permitted to borrow, subject to continued covenant compliance and borrowing base requirements, from $10 million to $20.0 million. At the Company’s election, the interest rate applicable to borrowings under the amended line of credit may be based on the prime rate or the LIBOR. Prime rate-based rates vary from prime rate plus 0.75% per annum to prime rate plus 1.75% per annum, while LIBOR-based rates vary from LIBOR plus 3.75% per annum to LIBOR plus 4.25% per annum. The amended line of credit is secured by a first priority security interest in all assets of the Company, including those at the East Providence facility, except for certain exclusions. | |
At September 30, 2014 and December 31, 2013, the Company had drawn $0.0 million and $1.0 million, respectively, on the line of credit. The Company also had outstanding letters of credit backed by the line of credit of $1.7 million and $1.2 million at September 30, 2014 and December 31, 2013, respectively, which reduce the funds otherwise available to the Company. Based on the available borrowing base, the effective amount available to the Company at September 30, 2014 was $10.7 million due to the $1.7 million of outstanding letters of credit. Under the amended line of credit, the Company is required to comply with financial covenants relating to, among other items, free cash flow and liquidity and other non-financial covenants. At September 30, 2014, the Company was in compliance with all such financial covenants. |

In March 2013, the Company recorded decreases in the redemption value of the Company’s Series B and Series A of $30.0 million and $56.1 million, respectively, reflecting the changes in the fair market value of the Series B and Series A at the time of the March 2013 NPA. Given that the release of the redemption rights substantially impacted the fair value of the Series B and Series A, the elimination of the rights was accounted for as an extinguishment of the securities. | |||||||||||||||||
During the nine months ended September 30, 2013, the Company recorded a gain on extinguishment of Series B and Series A of approximately $86.2 million recorded in additional paid-in capital available to common stockholders. Additionally, the remaining value of the Series B and Series A of $1.1 million subsequent to extinguishment was recorded in additional paid-in capital upon reclassification from temporary to permanent equity. As a result, the Company included in the computation of basic and diluted net income (loss) per share attributable to common stockholders preferred stock deemed dividends aggregating $29.6 million and $55.5 million for the Series B and A, respectively, during the nine months ended September 30, 2013. | |||||||||||||||||

As of September 30, 2014, there was no dilutive impact of the common stock options, restricted common stock units and common stock warrants.

As of September 30, 2013, the Company had $25.9 million of Senior Convertible Notes and $84.6 million of Convertible Notes outstanding, which were convertible into common stock upon the occurrence of an IPO at prices that were not determinable until the occurrence of the IPO (see notes 8 and 9). Because the necessary conditions for the conversion of these convertible notes had not been satisfied during the period ended September 30, 2013, the Company excluded these convertible notes from the table above and the calculation of diluted net (loss) income per share for the three and nine months ended September 30, 2013. |

The accompanying unaudited interim consolidated financial statements include the accounts of the Company and have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) and regulations of the Securities and Exchange Commission (the SEC) regarding interim financial reporting. Certain information and disclosures normally included in the consolidated financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2013 included in our prospectus dated June 12, 2014 and filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended, on June 16, 2014 (the Prospectus). | |||||||||||||||||

Reclassification | |||||||||||||||||
The December 31, 2013 balance sheet reflects a $0.2 million reclassification of the Company’s sales returns reserve from a component of accrued expenses to a reduction of accounts receivable, a $0.1 million reclassification of other assets to prepaid expenses and other current assets and a reclassification of $0.1 million of other long term liabilities to other current liabilities to conform to the current period’s presentation. The change has no impact on the results of operations. | |||||||||||||||||
Use of Estimates | ' | ||||||||||||||||
Use of Estimates | |||||||||||||||||
The preparation of the consolidated financial statements requires the Company to make a number of estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Significant items subject to such estimates and assumptions include allowances for doubtful accounts, inventory valuation, the carrying amount of property and equipment, fair value of debt and capital stock, stock-based compensation and deferred income taxes. The Company evaluates its estimates and assumptions on an on-going basis using historical experience and other factors, including the current economic environment, which it believes to be reasonable under the circumstances. Management adjusts such estimates and assumptions when facts and circumstances dictate. Illiquid credit markets, volatile equity markets and declines in business investment increase the uncertainty inherent in such estimates and assumptions. As future events and their effects cannot be determined with precision, actual results could differ significantly from these estimates. Changes in these estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. | |||||||||||||||||

Fair Value of Financial Instruments | ' | ||||||||||||||||
Fair Value of Financial Instruments | |||||||||||||||||
Fair value is an exit price that represents the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. Accordingly, fair value is a market-based measurement that should be determined based on assumptions that market participants would use in pricing an asset or liability. The Company discloses the manner in which fair value is determined for assets and liabilities based on a three-tiered fair value hierarchy. The hierarchy ranks the quality and reliability of the information used to determine the fair values. The three levels of inputs described in the standard are: | |||||||||||||||||
Level 1: | Quoted prices in active markets for identical assets or liabilities. | ||||||||||||||||
Level 2: | Observable inputs, other than Level 1 prices, for the assets or liabilities, either directly or indirectly, for substantially the full term of the assets or liabilities. | ||||||||||||||||
Level 3: | Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. | ||||||||||||||||
Under the Fair Value Option Subsections of Financial Accounting Standards Board (FASB) ASC Subtopic 825-10, Financial Instruments — Overall, the Company has the irrevocable option to report most financial assets and financial liabilities at fair value on an instrument by instrument basis, with changes in fair value reported in earnings each reporting period. As a result of electing this option, the Company had recorded its Subordinated Notes, Senior Convertible Notes and Convertible Notes at fair value in order to measure these liabilities at amounts that more accurately reflect the economics of these instruments (see notes 7, 8 and 9). | |||||||||||||||||
During the nine months ended September 30, 2014 and at December 31, 2013 the Company valued its Subordinated Notes, Senior Convertible Notes and Convertible Notes utilizing Level 3 inputs. | |||||||||||||||||
Stock-based Compensation | ' | ||||||||||||||||
Stock-based Compensation | |||||||||||||||||
Stock-based compensation cost is measured at the grant date based on the fair value of the award. Expense is recognized on a straight-line basis over the requisite service period for all awards with service conditions. For performance-based awards, the grant date fair value is recognized as expense when the condition is probable of being achieved, and then on a graded basis over the requisite service period. The Company uses the Black-Scholes option-pricing model to determine the fair value of service-based awards, which requires a number of complex and subjective assumptions including fair value of the underlying security, the expected volatility of the underlying security, a risk-free interest rate, the expected term of the option and the forfeiture rate. For performance-based stock options issued during the year ended December 31, 2013, the Company used a Monte Carlo simulation model to estimate the number of options the Company expected to remain outstanding and eligible for vesting upon completion of an IPO. The simulation model was based on a number of complex assumptions including the terms of the performance condition, the expected value of the Company’s common stock at the time of its IPO, the expected time from the date of grant to its IPO, and expected volatility. The compensation cost of these performance-based options was determined by multiplying the Black-Scholes estimate of grant date fair value by the percentage of options expected to remain outstanding and eligible for vesting upon completion of the Company’s IPO. As a result of the closing of the IPO, the Company recorded $5.6 million of stock-based compensation related to these performance-based awards during the nine months ended September 30, 2014. | |||||||||||||||||
Upon the completion of the IPO, the Company issued 61,816 shares of restricted common stock with an aggregate value at issuance of approximately $0.7 million to its non-employee directors. In September 2014 the Company issued 318,517 restricted common stock units (RSU) and non-qualified stock options (NSO) to purchase 934,018 shares of common stock to employees under the 2014 Equity Plan. The RSUs and NSOs will vest over a four year period for certain employees and over a three year period for other employees. | |||||||||||||||||
Earnings per Share | ' | ||||||||||||||||
Earnings per Share | |||||||||||||||||
Prior to the IPO, net income (loss) per common share was calculated using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for the holders of the Company’s common shares and participating securities. Prior to their conversion to common stock at the time of the Company’s IPO, the Company’s Series A preferred stock, Series B preferred stock and Series C preferred stock warrants contained participation rights in any dividend to be paid by the Company to holders of its common shares and were deemed to be participating securities. Net income (loss) available to common shareholders and participating securities was allocated to each share on an as-if-converted basis as if all of the earnings for the period had been distributed. The participating securities did not include a contractual obligation to share in losses of the Company and were not included in the calculation of net loss per share in the periods that have a net loss. | |||||||||||||||||
Diluted net income (loss) per share is computed using the more dilutive of (a) the two-class method, or (b) the if-converted method. The Company allocates net income (loss) first to preferred stockholders and holders of warrants to purchase preferred stock based on dividend rights and then to common, preferred stockholders and preferred warrant holders based on ownership interests. The weighted-average number of common shares included in the computation of diluted net income (loss) gives effect to all potentially dilutive common equivalent shares, including outstanding stock options and warrants. Common equivalent shares are excluded from the computation of diluted net income (loss) per share if their effect is antidilutive. | |||||||||||||||||
Subsequent to the IPO, the Company calculates net income (loss) per common share based on the weighted-average number of common shares outstanding during each period. Potential common stock equivalents are determined using the treasury stock method. The weighted-average number of common shares included in the computation of diluted net income (loss) gives effect to all potentially dilutive common equivalent shares, including outstanding stock options, restricted common stock units and warrants. Common equivalent shares are excluded from the computation of diluted net income (loss) per share if their effect is antidilutive. | |||||||||||||||||

In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers. The standard will eliminate the transaction- and industry-specific revenue recognition guidance under current U.S. GAAP and replace it with a principle based approach for determining revenue recognition. Public entities are required to apply the revenue recognition standard for annual reporting period beginning on or after December 15, 2016, including interim periods within that annual reporting period. Early application is not permitted. The Company has not yet selected a transition method and is evaluating the effect that the updated standard will have on its consolidated financial statements and related disclosures. | |||||||||||||||||
In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements — Going Concern: Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The standard requires an entity’s management to evaluate whether there are conditions or events that raise substantial doubt about the entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Public entities are required to apply standards for annual reporting periods ending after December 15, 2016, and interim periods thereafter. Early application is permitted. The Company is evaluating the impact of this standard on its consolidated financial statements. | |||||||||||||||||
From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. |
