Organization and Basis of Presentation
Organization and Basis of Presentation	Note 1. Organization and Basis of Presentation Organization and Basis of Presentation Glaukos Corporation (Glaukos or the Company), incorporated in Delaware on July 14, 1998, is a developer, manufacturer and marketer of medical devices for the treatment of glaucoma. The accompanying consolidated financial statements include the accounts of Glaukos, its wholly-owned subsidiaries Glaukos Australia Pty. Ltd., Glaukos Canada Inc., Glaukos Europe GmbH , Glaukos Japan GK and until June 30, 2015, affiliated entity DOSE Medical Corporation (DOSE) (see Note 9). All significant intercompany balances and transactions among the consolidated entities have been eliminated in consolidation. Reverse Stock Split On June 11, 2015, the Company effected a 1 for 2.5 share reverse stock split of the Company’s common stock and convertible preferred stock. Neither the par value nor the authorized number of shares was adjusted as a result of the reverse stock split. All issued and outstanding common stock, shares of common stock held in treasury, convertible preferred stock, warrants, and per share amounts contained in the accompanying financial statements and notes to the financial statements have been retroactively adjusted to give effect to the reverse stock split for all periods presented. Initial Public Offering On June 30, 2015, the Company completed an initial public offering (IPO), selling 6.9 million newly issued shares of common stock at a price of $18.00 per share. The IPO generated net cash proceeds of $113.6 million, after deducting underwriting commissions of approximately $8.7 million and other related expenses of $1.9 million. The underwriting commissions and offering costs were reflected as a reduction to the IPO proceeds included in additional paid-in capital. Immediately prior to the closing of the IPO, all unexercised warrants to purchase shares of Series D convertible preferred stock were net exercised at the IPO price per share, and then all outstanding shares of convertible preferred stock automatically converted into 21.7 million shares of common stock. Following the closing of the IPO, there were no shares of preferred stock and no warrants to purchase shares of Series D convertible preferred stock outstanding. An additional 4.5 million shares of common stock were reserved for issuance under the Company’s 2015 Omnibus Incentive Compensation Plan and 450,000 shares of common stock were reserved for the Company’s 2015 Employee Stock Purchase Plan. Acquisition of certain DOSE Medical Corporation Assets On June 30, 2015, the Company acquired certain assets from DOSE, including the iDose product line, in exchange for a cash payment of $15.0 million and the elimination of all amounts owed by DOSE to the Company. In addition to an asset purchase, the parties agreed to an amended and restated patent license agreement and an amended and restated transition services agreement that provides for limited support from the Company to DOSE for a period of up to three years (see Note 9).

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies There have been no significant changes in the Company’s significant accounting policies during the three and nine months ended September 30, 2015 as compared with those disclosed in its audited annual financial statements included in its final prospectus filed with the United States Securities and Exchange Commission (SEC) pursuant to R ule 424(b)(4) on June 25, 2015 relating to the Company’s Registration Statement on Form S-1 (File No. 333-204091) for the Company’s IPO . Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Management considers many factors in selecting appropriate financial accounting policies and controls and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. The most significant estimates in the accompanying condensed consolidated financial statements relate to revenue recognition, clinical trial expense accruals, collectability reserves, inventory reserves, fair value of the stock warrant liability and stock-based compensation expense. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, this process may result in actual results differing materially from those estimated amounts used in the preparation of the financial statements. Unaudited Interim Financial Information The accompanying interim condensed consolidated financial statements are unaudited. The unaudited interim financial statements have been prepared on a basis consistent with the audited financial statements and follow the requirements of the SEC for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by GAAP can be condensed or omitted. In the opinion of management, the unaudited interim financial statements reflect all adjustments, which include normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of September 30, 2015 and its results of operations, comprehensive loss and cash flows for the periods presented. These interim financial statements do not include all disclosures required by GAAP and should be read in conjunction with the Company’s financial statements and accompanying notes for the fiscal year ended December 31, 2014, which are contained in the Company’s final prospectus filed by the Company with the SEC pursuant to Rule 424(b)(4) on June 25, 2015 relating to the Company’s Registration Statement on Form S-1/A (File No. 333-204091) for the Company’s IPO. The results for the periods ended September 30, 2015 are not necessarily indicative of the results to be expected for the year ended December 31, 2015 or for any other interim period. Foreign Currency Translation The accompanying condensed consolidated financial statements are presented in U.S. dollars. The Company considers the local currency to be the functional currency for its international subsidiaries – the Australian Dollar for Glaukos Australia Pty. Ltd., the Canadian Dollar for Glaukos Canada Inc., the Euro for Glaukos Europe GmbH and the Yen for Glaukos Japan GK. Accordingly, their assets and liabilities are translated into U.S. dollars using the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at average exchange rates prevailing throughout the periods presented. Currency translation adjustments arising from period to period are charged or credited to accumulated other comprehensive income in stockholders’ equity (deficit). For the three months ended September 30, 2015 and 2014, the Company reported income from foreign currency translation adjustments of approximately $12,000 and $31,000, respectively . For the nine months ended September 30, 2015 and 2014, the Company reported income from foreign currency translation adjustments of approximately $51,000 and $53,000, respectively . Realized gains and losses resulting from foreign currency transactions are included in the consolidated statements of operations. For the three months ended September 30, 2015 and 2014, the Company reported foreign currency transaction losses of approximately $30,000 and $20,000 , respectively. For the nine months ended September 30, 2015 and 2014, the Company reported foreign currency transaction losses of approximately $115,000 and $34,000, respectively . Cash and Cash Equivalents The Company invests its excess cash in investment-grade marketable securities, including money market funds, money market securities, corporate bonds, and corporate commercial paper and U.S. government agency bonds. For financial reporting purposes, liquid investment instruments purchased with an original maturity of three months or less are considered to be cash equivalents. Cash and cash equivalents are recorded at face value or cost, which approximates fair market value. From time to time, the Company maintains cash balances in excess of amounts insured by the Federal Deposit Insurance Commission (FDIC). Investments are stated at fair value as determined by quoted market prices. Investments are considered available-for-sale and, accordingly, unrealized gains and losses are included in accumulated other comprehensive income within stockholders’ equity (deficit). The Company’s entire investment portfolio, except for restricted cash, is considered to be available for use in current operations and, accordingly, all such investments are stated at fair value using quoted market prices and classified as current assets, although the stated maturity of individual investments may be one year or more beyond the balance sheet date. The Company did not have any trading securities or restricted investments at September 30, 2015 and December 31, 2014. Realized gains and losses and declines in value, if any, judged to be other-than-temporary or available-for-sale securities, are reported in interest income or expense, net. When securities are sold, any associated unrealized gain or loss previously reported as a separate component of stockholders’ equity is reclassified out of stockholders’ equity and recorded in the statements of operations in the period sold. Accrued interest and dividends are included in interest income. The Company periodically reviews its available-for-sale securities for other-than-temporary declines in fair value below the cost basis, and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Restricted Cash The Company has a credit card facility with its primary operating bank which is collateralized by certificates of deposits maintained at the bank Fair Value Measurements Assets and liabilities are measured using quoted prices in active markets and total fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are valued by reference to similar assets or liabilities, adjusted for contract restrictions and other terms specific to that asset or liability. For these items, a significant portion of fair value is derived by reference to quoted prices of similar assets or liabilities in active markets. For all remaining assets and liabilities, fair value is derived using a fair value model, such as a discounted cash flow model or Black-Scholes model. Fair Value of Financial Instruments The carrying amounts of accounts receivable, accounts payable, and accrued liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments. Based on the borrowing rates currently available to the Company for loans with similar terms, the Company believes that the fair value of long-term debt approximates its carrying value. The carrying amount of the warrant liability and non-controlling interest represent their fair values. The valuation of assets and liabilities are subject to fair value measurements using a three-tiered approach and fair value measurements are classified and disclosed by the Company in one of the following three categories: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Revenue Recognition The Company recognizes revenue from product sales when the following criteria are met: goods are shipped, title and risk of loss has transferred to its customers, persuasive evidence of an arrangement exists and collectability is reasonably assured. Persuasive evidence of an arrangement exists when there is a contractual arrangement in place with the customer. Delivery has occurred when a product is shipped. If persuasive evidence of an arrangement exists and delivery has occurred, the Company determines whether the invoiced amount is fixed or determinable and collectability of the invoiced amount is reasonably assured. The Company assesses whether the invoiced amount is fixed or determinable based on the existing arrangement with the customer, including whether the Company has sufficient history with a customer to reliably estimate the customer’s payment patterns. The Company assesses collectability by evaluating historical cash receipts and individual customer outstanding balances. To the extent all criteria set forth above are not satisfied at the time of shipment, revenue is recognized when cash is received from the customer. Customers are not granted specific rights of return; however, the Company may permit returns of product from customers if such product is returned in a timely manner and in good condition. The Company provides a warranty on its products for one year from the date of shipment, and any product found to be defective or out of specification will be replaced at no charge during the warranty period. Estimated allowances for sales returns and warranty replacements are recorded at the time of sale of the product and are estimated based upon the historical patterns of product returns matched against sales, and an evaluation of specific factors that may increase the risk of product returns. Product returns and warranty replacements to date have been consistent with amounts reserved or accrued and have not been significant. Stock Warrants The Company has issued freestanding warrants to purchase shares of its common stock, which are accounted for as a liability because they contain a down-round protection provision that is outside the control of the Company. The warrants are recorded on the Company’s balance sheet at their fair value as determined on the date of issuance and are revalued at each subsequent balance sheet date, with fair value changes recognized as other income or expense in the accompanying condensed consolidated statements of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrants. The Company estimates the fair value of the liability using option pricing models and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, including assumptions for expected volatility, expected life, yield, and risk-free interest rate. Research and Development Expenses Major components of research and development expense include personnel costs, preclinical studies, clinical trials and related clinical product manufacturing, materials and supplies, and fees paid to consultants. Research and development costs are expensed as goods are received or services are rendered. Costs to acquire technologies to be used in research and development that have not reached technological feasibility and have no alternative future use are also expensed as incurred. At each financial reporting date, the Company accrues the estimated costs of clinical study activities performed by third party clinical sites with whom the Company has agreements that provide for fees based upon the quantities of subjects enrolled and clinical evaluation visits that occur over the life of the study. The estimates are determined based upon a review of the agreements and data collected by internal and external clinical personnel as to the status of enrollment and subject visits, and are based upon the facts and circumstances known to the Company at each financial reporting date. If the actual performance of activities varies from the assumptions used in the estimates, the accruals are adjusted accordingly. There have been no material adjustments to the Company’s prior period accrued estimates for clinical trial activities through September 30, 2015 and December 31, 2014. Stock-Based Compensation The Company recognizes compensation expense for all stock-based awards granted to employees and nonemployees, including members of its Board of Directors. The fair value of stock-based awards made to employees is estimated at the grant date using the Black-Scholes option-pricing model, and the portion that is ultimately expected to vest is recognized as compensation cost over the requisite service period using the straight-line method. The determination of the fair value-based measurement of stock options on the date of grant using an option pricing model is affected by the determination of the fair value of the underlying stock as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the Company’s stock price volatility over the expected term of the grants, and actual and projected employee stock option exercise behaviors. In the future, as additional empirical evidence regarding these estimates becomes available, the Company may change or refine its approach of deriving them, and these changes could impact the fair value-based measurement of stock options granted in the future. Changes in the fair value-based measurement of stock awards could materially impact the Company’s operating results. The fair values of stock-based awards made to nonemployees are remeasured at each reporting period using the Black-Scholes option-pricing model. Compensation expense for these stock-based awards is determined by applying the remeasured fair values to the shares that have vested during a period. Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted average number of common shares that were outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the sum of the weighted average number of dilutive common share equivalents outstanding for the period determined using the treasury-stock method. Common stock equivalents are comprised of convertible preferred stock, preferred stock warrants, and stock options outstanding under the Company’s stock option plans. The calculation of diluted net loss per share requires that, to the extent the average fair value of the underlying shares for the reporting period exceeds the exercise price of the warrants and the presumed exercise of such securities are dilutive to net loss per share for the period, adjustments to net loss used in the calculation are required to remove the change in fair value of the warrants for the period. Likewise, adjustments to the denominator are required to reflect the related dilutive shares. The Company’s computation of loss per share is as follows (in thousands, except per share amounts): Three Months Ended Nine Months Ended September 30, September 30, 2015 2014 2015 2014 Numerator: Net loss attributable to Glaukos Corporation - basic $ $ $ $ Adjustment for revaluation of warrants - - - Net loss attributable to Glaukos Corporation - diluted $ $ $ $ Denominator: Weighted average number of common shares oustanding - basic Common stock equivalents from outstanding common stock warrants - - - Weighted average number of common shares oustanding - diluted Basic net loss per share attributable to Glaukos Corporation common stockholders $ $ $ $ Diluted net loss per share attributable to Glaukos Corporation common stockholders $ $ $ $ Potentially dilutive securities not included in the calculation of diluted net loss per share attributable to common stockholders because to do so would be anti-dilutive were as follows (in common stock equivalent shares, in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2015 2014 2015 2014 Convertible preferred stock outstanding - - Preferred stock warrants outstanding - - Common stock warrants outstanding - - Stock options outstanding Recent Accounting Pronouncements In May 2014, the FASB issued guidance codified in ASC 606, Revenue Recognition — Revenue from Contracts with Customers , which amends the guidance in former ASC 605, Revenue Recognition , which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB deferred the effective date for annual reporting periods beginning after December 15, 2017 (including interim periods within those periods). Early adoption is permitted to the original effective date of December 15, 2016 (including interim periods within those periods). The Company is currently evaluating the impact of the provisions of ASC 606 on its financial statements. In June 2014, the FASB issued an accounting standards update that requires a performance target that affects vesting of a share-based payment award and that could be achieved after the requisite service period to be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. Compensation cost should be recognized over the required service period if it is probable that the performance target will be achieved. This guidance will be effective for fiscal years beginning after December 15, 2015, which will be the Company’s fiscal year 2016, with early adoption permitted. The Company does not expect the adoption of the guidance to have material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern . This ASU introduces an explicit requirement for management to assess if there is substantial doubt about an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. In connection with each annual and interim period, management must assess if there is substantial doubt about an entity’s ability to continue as a going concern within one year after the issuance date. Disclosures are required if conditions give rise to substantial doubt. ASU 2014-15 is effective for all entities in the first annual period ending after December 15, 2016. The Company is currently assessing the potential effects of this ASU on the consolidated financial statements . In February 2015, the FASB issued Accounting Standards Update (ASU) 2015-02, Amendments to the Consolidation Analysis , which eliminates the deferral of FAS 167, which allows reporting entities with interests in certain investment funds to follow the consolidation guidance in FIN 46(R), and make other changes to both the variable interest model and the voting model. The ASU is effective for annual periods beginning after December 15, 2015 and interim periods therein, with early adoption permitted. During the quarter ended June 30, 2015, the Company early adopted the provisions of the ASU effective January 1, 2015. Based on the asset purchase transaction with DOSE on June 30, 2015 and the Company’s evaluation of the modified relationship with DOSE, management determined that after the transaction DOSE is no longer a VIE requiring consolidation (See Note 9). In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330), Simplifying the Measurement of Inventory , which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance must be applied on a prospective basis and is effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. The Company does not believe the implementation of this standard will have a material impact on its financial statements.

Fair Value Measurements
Fair Value Measurements	Note 4. Fair Value Measurements Fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As such, 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 following tables present information about the Company's financial assets and financial liabilities measured at fair value on a recurring basis as of September 30, 2015 and December 31, 2014, and indicates the fair value hierarchy of the valuation techniques utilized by the Company to determine such fair value (in thousands): September 30, At September 30, 2015 2015 (Level 1) (Level 2) (Level 3) Assets Cash equivalents $ - $ - $ - $ - Total assets $ - $ - $ - $ - Liabilities Stock warrant liabilities $ $ - $ - $ Total liabilities $ $ - $ - $ December 31, At December 31, 2014 2014 (Level 1) (Level 2) (Level 3) Assets Cash equivalents $ - $ - $ - $ - Total assets $ - $ - $ - $ - Liabilities Stock warrant liabilities $ $ - $ - $ Total liabilities $ $ - $ - $ The stock warrant liabilities are recorded at fair value using the Black-Scholes option pricing model, which requires inputs such as the expected term of the warrants, volatility and risk-free interest rate. Some of these inputs are subjective and generally require significant analysis and judgment to develop. There were no transfers between levels within the fair value hierarchy during the periods presented. In conjunction with the Company’s February 2015 Amended and Restated Revolving Credit and Term Loan Agreement as more fully described in Note 5, the Company issued warrants to the lenders to purchase 11,298 shares of common stock at an exercise price of $8.85 per share. Warrants to purchase 5,649 shares of common stock were exercised by the lenders in September 2015. For the nine months ended September 30, 2015, the Company recorded other expense of $0.2 million related to changes in the fair value of the warrants. The fair value of the warrants as of the issuance date was estimated to be $53,000 using an option pricing framework, considering multiple exit scenarios and the probability of a down-round financing, with the following assumptions deemed by the Company to be significant unobservable inputs: risk-free interest rate of 1.9%; dividend yield of 0.0%; expected volatility of 70.0%; and an expected life of 7 years. The fair value of the warrants to purchase the remaining 5,649 shares of common stock as of September 30, 2015 was estimated to be $103,000 using the Black-Scholes valuation model with the following assumptions deemed by the Company to be significant unobservable inputs: risk-free interest rate of 1.6%; dividend yield of 0.0%; expected volatility of 55.2%; and an expected life of 6.4 years. If the value of the underlying shares were to decrease by 10%, the fair value of the warrants would decrease by approximately the same amount. In conjunction with loans to the Company in 2010 from certain holders of the Company's then-outstanding preferred stock, which were subsequently converted into preferred stock in 2011, the Company issued warrants to such holders to purchase 156,860 shares of Series D convertible preferred stock at $7.65 per share. Warrants to purchase 29,333 shares were exercised in 2014. Warrants to purchase 127,526 shares were exercised in 2015; 49,410 warrant shares were exercised with cash payment and 78,116 warrant shares were net exercised into 44,914 shares of common stock immediately prior to the IPO at the IPO price per share. For the nine months ended September 30, 2015 and 2014, the Company recorded other expense of $0.9 million and $0.1 million, respectively, related to changes in the fair value of the warrants. The fair value of the warrants as of December 31, 2014 was estimated to be $0.4 million using the Black-Scholes valuation model with the following assumptions deemed by the Company to be significant unobservable inputs: risk-free interest rate of 1.0%; dividend yield of 0.0%; expected volatility of 48.5%; and an expected life of 2.7 years.

Long-Term Debt.
Long-Term Debt	Note 5. Long-Term Debt Bank Loan Facility In June 2013, the Company entered into a Loan and Security Agreement (the Credit Agreement) with the Company’s primary bank, under which the bank agreed to extend to the Company a revolving loan in the maximum principal amount of $6.0 million. Advances under the loan were limited to the lesser of (i) $6.0 million or (ii) 77% of the sum of cash, cash equivalents and eligible domestic accounts receivable. The entire unpaid principal amount plus any accrued but unpaid interest were to become due and payable in full on June 5, 2015. Obligations under the Credit Agreement bore interest on the outstanding daily balance thereof at the bank’s prime rate plus 0.5% (3.75% at December 31, 2014). Amounts owed were secured by a first priority security interest in all of the Company’s assets, excluding intellectual property. The Credit Agreement was subject to certain reporting and financial covenants which, if not met, could have constitute d an event of default. As of December 31, 2014, the balance outstanding on the line of credit was $1.9 million. In February 2015, the Agreement was amended and restated, at which time the balance outstanding on the line of credit was $2.1 million. In February 2015, the Company and its primary bank executed an Amended and Restated Revolving Credit and Term Loan Agreement (the Amended Credit Agreement) which provide d for a $5.0 million senior secured term loan, a $5.0 million senior secured draw-to term loan and an $8.0 million senior secured revolving credit facility. Amounts owed under the Amended Credit Agreement were secured by a first priority security interest in all of the Company’s assets, excluding intell ectual property. The Amended Credit Agreement wa s subject to certain reporting and financial covenants which, if not met, could have constitute d an event of default. On the closing date, the Company received $5.0 million cash under the senior secured term loan and immediately paid off the $2.1 million balance outstanding on the line of credit. The Company incurred loan origination fees of $41,000 which was recorded as a loan discount, and debt issuance costs of $0.1 million which was recorded as a deferred asset. The term loan require d quarterly principal payments of $0.4 million over a three -year period beginning May 1, 2016. The senior secured draw-to term loan was available through February 23, 2016 for advances up to an aggregate of $5.0 million, and it required quarterly principal payments equal to 1/12 of the aggregate principal amount over a three -year period beginning May 1, 2016. As of Ju ly 3 1 , 2015, the Company had drawn $2.0 million under the draw-to term loan. The senior secured term loan and draw-to term loan would have mature d and would have been required to be fully paid by February 23, 2019. Advances under the revolving line of credit were limited to the lesser of (i) $8.0 million or (ii) a calculated borrowing base consisting of (a) 80% of eligible accounts receivable plus (b) the lesser of 30% of eligible inventory or $1.5 million. The entire unpaid principal amount plus any accrued but unpaid interest under the revolving line of credit was due and payable in full on February 23, 2017. The Company was permitted to make voluntary prepayments of the term and draw-to term loans without prepayment penalty. On July 31, 2015, the Company paid off in full all amounts outstanding under the Amended Credit Agreement with the payment of $7.0 million in principal plus all interest and fees payable through the payoff date , and recorded a loss on extinguishment of debt in the amount of $0.2 million . Accordingly, this facility is no longer outstanding and available to the Company. Outstanding balances under the senior secured term loan and senior secured draw-to term loan bore interest on the outstanding daily balance at an annual percentage rate equal to the bank’s prime rate plus 2% . At the Company’s option all or a portion of the amounts owed under any of the senior secured term loan and draw-to term loan may have been converted into Eurodollar-based advances at an annual percentage rate equal to LIBOR plus 3% . Outstanding balances under the revolving credit facility bore interest on the outstanding daily balance thereof at an annual percentage rate equal to the bank’s prime rate plus 1.75% . At the Company’s option all or a portion of the amounts owed under the revolving credit facility may have been converted into Eurodollar-based advances at an annual percentage rate equal to LIBOR plus 2.75% . In connection with the execution of the Amended Credit Agreement, the Company issued warrants to the lenders to purchase an aggregate of 11,298 shares of common stock at an exercise price of $8.85 per share (See Note 4). The Company accounted for the debt discount and deferred asset utilizing the effective interest method. Amortization of debt discount and the deferred asset to interest expense amounted to $0 and $15,000 f or the three months and nine months ended September 30, 2015, respectively. Notes Payable in Connection with GMP Vision Solutions In January 2007, the Company entered into an agreement (the Original GMP Agreement) with GMP Vision Solutions, Inc. (GMP) to acquire certain in-process research and development. In connection with the Original GMP A greement, the Company was obligated to make periodic royalty payments equal to a single-digit percentage of revenues received for royalty-bearing products and periodic royalty payments at a higher royalty rate applied to all amounts received in connection with the grant of licenses or sublicenses of the related intellectual property. There was no related royalty expense recorded in cost of sales in the periods ended September 30, 201 5 and 201 4 . In December 2012, the Company entered into an agreement with GMP in which it paid GMP $1.0 million for a 90 -day option to buy out all remaining royalties payable to GMP. In April 2013, the option expired unexercised and , as provided in the agreement, the $1.0 million payment satisfied the Company’s obligation to pay the first $1.0 million in royalties earned beginning on January 1, 2013. The $1.0 million payment was recorded in cost of sales in the year ended December 31, 2012. In November 2013, the Company entered into an amended agreement with GMP in which remaining royalties payable to GMP (the Buyout Agreement) were canceled in exchange for the issuance of $17.5 million in promissory notes payable to GMP and a party related to GMP (together, the GMP Note Parties). The GMP notes are collateralized by all of the Company’s assets, excluding intellectual property. However, in connection with the Buyout Agreement, the GMP Note Parties entered into agreements with the Company’s primary bank pursuant to which any collateralized interests, liens, rights of payment or ability to initiate any enforcement actions in the event of an event of default were subordinate to the rights of the Company’s primary bank under the Credit Agreement (and subsequently, the Amended Credit Agreement) which was paid off in full on July 31, 2015 . The Buyout Agreement also calls for a payment of up to $2.0 million in the event of a sale of the Company meeting certain criteria. The promissory notes carry an interest rate of 5% per annum and required monthly interest - only payments from November 30, 2013 through December 31, 2014 of $72,900 , followed by 24 equal monthly principal and interest payments of $767,700 , which began on January 31, 2015, and end on December 31, 2016. The Company concluded that the $17.5 million transaction represented the purchase of an intangible asset. The Company estimated a useful life of five years over which the intangible asset will be amortized to cost of sales in the statements of operations, which amortization period was determined after consideration of the projected outgoing royalty payment stream had the Buyout A greement not occurred, and the remaining life of the patents obtained in the Original GMP Agreement. After determining that the pattern of future cash flows associated with this intangible asset could not be reliably estimated with a high level of precision, the Company concluded that the intangible asset will be amortized on a straight-line basis over the useful life. The following reflects the composition of intangible assets, net (in thousands): September 30, December 31, 2015 2014 Gross amount $ $ Accumulated amortization Total $ $ Weighted average amortization period (in months) The Company recorded related amortization expense in cost of sales of $0.9 million and $0.9 million in the three months ended September 30, 201 5 and 201 4 , respectively, and $2.6 million and $2.6 million in the nine months ended September 30, 201 5 and 201 4 , respectively.

Stock-Based Compensation.
Stock-Based Compensation	Note 7. Stock-Based Compensation The Company has four stock-based compensation plans (collectively, the Stock Plans)—the 2001 Stock Option Plan (the 2001 Stock Plan), the 2011 Stock Plan, the 2015 Omnibus Incentive Compensation Plan (the 2015 Stock Plan) and the 2015 Employee Stock Purchase Plan (the ESPP). The purpose of these plans is to provide incentives to employees, directors and nonemployee consultants. The Company will no longer grant any awards under the 2001 Stock Plan and the 2011 Stock Plan. The maximum term of any stock options granted under the Stock Plans is 10 years. The options generally vest 25% on the first anniversary of the original vesting date, with the balance vesting monthly or annually over the remaining three years. Stock options are granted at exercise prices at least equal to the fair value of the underlying stock at the date of the grant. The Company reserved an aggregate of 4.5 million shares of common stock for issuance under the 2015 Stock Plan, and 450,000 shares of common stock for issuance under the ESPP. The ESPP is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. Stock options granted pursuant to the 2001 Stock Plan and 2011 Stock Plan generally permit optionees to elect to exercise unvested options in exchange for restricted common stock. All unvested shares issued upon the early exercise of stock options, so long as they remain unvested, are subject to the Company's right of repurchase at the optionee's original exercise price for a 90-day period beginning on the date that an optionee's service with the Company voluntarily or involuntarily terminates. Consistent with authoritative guidance, early exercises are not considered exercises for accounting purposes. Cash received for the exercise of unvested options is recorded as a liability, which liability is released to equity at each reporting date as the shares vest. During the three months ended September 30, 2015 and 2014, there were no option exercises for unvested shares, and during the nine months ended September 30, 2015 and 2014, there were option exercises for 337 and 55,908 unves ted shares, respectively. As of September 30, 2015 and December 31, 2014, 22,033 , and 38,678 shares, respectively, remained subject to a repurchase right. As of September 30, 2015 and December 31, 2014, the related liability, which is included in other accrued liabilities in the accompanying consolidated balance sheets, was approximately $88,000 and $153,000 , respectively. The following table summarizes stock option activity under the 2001 Stock Plan, 2011 Stock Plan and 2015 Stock Plan (in thousands): Number of Shares Underlying Options Outstanding at December 31, 2014 Granted (unaudited) Exercised (unaudited) Canceled/forfeited/expired (unaudited) Outstanding at September 30, 2015 (unaudited) Exercisable at September 30, 2015 (unaudited) The following table summarizes the allocation of stock-based compensation in the accompanying condensed consolidated statements of operations (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2015 2014 2015 2014 Cost of sales $ $ $ $ Selling, general and administrative Research and development Total $ $ $ $ Stock-Based Awards to Employees The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model applying the assumptions noted in the following table. The weighted average assumptions used to estimate the fair value of options granted to employees were as follows: Three Months Ended Nine Months Ended September 30, September 30, 2015 2014 2015 2014 Risk-free interest rate % % % % Expected dividend yield % % % % Expected volatility % % % % Expected term (in years) In July 2014, the Company granted stock options to purchase an aggregate of 1.2 million shares of common stock, which options contain a performance condition such that they would only become exercisable in the event that the Company’s common stock was listed on a national securities exchange within one year from the date of grant. In accordance with authoritative guidance, the Company did not record any compensation expense associated with the grants until the performance condition was satisfied in the three month period ended June 30, 2015. Upon the completion of the IPO on June 30, 2015, the Company immediately recognized cumulative compensation cost of $3.8 million for the grants as if the method had been applied since the date of grant using the required graded accelerated attribution method, and the Company will record compensation expense over the remainder of the four -year vesting period using this method. Stock options granted subsequent to July 2014 do not contain a performance condition.

Regents of the University of California On December 30, 2014, the Company executed an agreement (the UC Agreement) with the Regents of the University of California (the Regents) to correct inventorship in connection with a group of the Company’s U.S. patents (the Patent Rights) and to obtain from the Regents a covenant that it did not and would not claim any right or title to the Patent Rights and will not challenge or assist any others in challenging the Patent Rights. In connection with the Agreement, Glaukos agreed to pay to the Regents the sum of $2.7 million via five payments during the course of 2015, and, beginning with sales on or after January 1, 2015, to pay a low single-digit percentage of worldwide net sales of certain current and future products, including the Company’s iStent products, with a required minimum annual payment of $500,000. This ongoing royalty payment terminates on the date that the last of the Patent Rights expires, which is currently expected to be in 2022. The $2.7 million obligation, net of imputed interest of $0.1 million, was accrued as of December 31, 2014 and charged to cost of sales in the year ended December 31, 2014. Under the terms of the UC A greement, the payments comprising the $2.7 million obligation were due within 60 days of the IPO, and, accordingly, the Company paid the remaining balance due of $1.8 million prior to August 29, 2015.

Variable Interest Entity
Variable Interest Entity	Note 9 . Variable Interest Entity In October 2009, the Company formed a wholly-owned subsidiary, DOSE Medical Corporation and in April 2010, the Company distributed all of its shares of common stock of DOSE via a stock dividend to the Company’s stockholders of record as of the close of business on March 31, 2010. Since its formation, the Company had provided DOSE with a small number of leased employees, management services and space, all of which had been charged to DOSE and pursuant to written agreements between the parties. Additionally, the Company had provided DOSE the cash required to fund its operations that, together with accrued interest and charges for the aforementioned services, the Company had recorded in an intercompany receivable account. Up until the transaction on June 30, 2015 described below , the Company had accounted for DOSE as a variable interest entity in which it had a variable interest in all reporting periods since the formation of DOSE. Accordingly, the Company’s consolidated financial statements include the accounts of DOSE, with all intercompany balances eliminated and with the deficit balance of DOSE's net assets reflected as noncontrolling interest, up to but excluding June 30, 2015. On June 30, 2015, the Company completed a transaction initially executed in July 2014, the closing of which was contingent upon the successful completion of an IPO. Pursuant to the terms of the asset purchase agreement, the Company acquired from DOSE certain assets, including the iDose product line, in exchange for payment of $15.0 million in cash and the elimination of the $10.9 million intercompany receivable owed by DOSE to the Company as of the closing date. In addition to the asset purchase agreement, the parties agreed to an amended and restated patent license agreement and an amended and restated transition services agreement that provides for limited support from the Company to DOSE for a period of up to three years. Either party can terminate the transition services agreement upon adequate written notice. Two members of the Company’s board of directors currently serve on the board of directors of DOSE. The Company has reconsidered its relationship with DOSE as a result of the transaction and has determined that the Company is no longer considered to be the primary beneficiary with the power to direct operations and the right to receive benefits/absorb losses of DOSE; therefore, upon the close of the transaction, the Company derecognized DOSE and will no longer consider it a consolidated entity in its financial statements. Accordingly, in the three months ended June 30, 2015, the Company recorded a charge to other expense in the amount of $25.7 million to reflect the deconsolidation of DOSE’ non-glaucoma related assets and noncontrolling interest.

Summary of Significant Accounting Policies
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP).
Use of Estimates	Use of Estimates The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results could differ materially from those estimates. Management considers many factors in selecting appropriate financial accounting policies and controls and in developing the estimates and assumptions that are used in the preparation of these financial statements. Management must apply significant judgment in this process. In addition, other factors may affect estimates, including expected business and operational changes, sensitivity and volatility associated with the assumptions used in developing estimates, and whether historical trends are expected to be representative of future trends. The estimation process often may yield a range of potentially reasonable estimates of the ultimate future outcomes, and management must select an amount that falls within that range of reasonable estimates. The most significant estimates in the accompanying condensed consolidated financial statements relate to revenue recognition, clinical trial expense accruals, collectability reserves, inventory reserves, fair value of the stock warrant liability and stock-based compensation expense. Although these estimates are based on the Company’s knowledge of current events and actions it may undertake in the future, this process may result in actual results differing materially from those estimated amounts used in the preparation of the financial statements.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying interim condensed consolidated financial statements are unaudited. The unaudited interim financial statements have been prepared on a basis consistent with the audited financial statements and follow the requirements of the SEC for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by GAAP can be condensed or omitted. In the opinion of management, the unaudited interim financial statements reflect all adjustments, which include normal recurring adjustments, necessary for the fair presentation of the Company’s financial position as of September 30, 2015 and its results of operations, comprehensive loss and cash flows for the periods presented. These interim financial statements do not include all disclosures required by GAAP and should be read in conjunction with the Company’s financial statements and accompanying notes for the fiscal year ended December 31, 2014, which are contained in the Company’s final prospectus filed by the Company with the SEC pursuant to Rule 424(b)(4) on June 25, 2015 relating to the Company’s Registration Statement on Form S-1/A (File No. 333-204091) for the Company’s IPO. The results for the periods ended September 30, 2015 are not necessarily indicative of the results to be expected for the year ended December 31, 2015 or for any other interim period.
Foreign Currency Translation	Foreign Currency Translation The accompanying condensed consolidated financial statements are presented in U.S. dollars. The Company considers the local currency to be the functional currency for its international subsidiaries – the Australian Dollar for Glaukos Australia Pty. Ltd., the Canadian Dollar for Glaukos Canada Inc., the Euro for Glaukos Europe GmbH and the Yen for Glaukos Japan GK. Accordingly, their assets and liabilities are translated into U.S. dollars using the exchange rate in effect on the balance sheet date. Revenues and expenses are translated at average exchange rates prevailing throughout the periods presented. Currency translation adjustments arising from period to period are charged or credited to accumulated other comprehensive income in stockholders’ equity (deficit). For the three months ended September 30, 2015 and 2014, the Company reported income from foreign currency translation adjustments of approximately $12,000 and $31,000, respectively . For the nine months ended September 30, 2015 and 2014, the Company reported income from foreign currency translation adjustments of approximately $51,000 and $53,000, respectively . Realized gains and losses resulting from foreign currency transactions are included in the consolidated statements of operations. For the three months ended September 30, 2015 and 2014, the Company reported foreign currency transaction losses of approximately $30,000 and $20,000 , respectively. For the nine months ended September 30, 2015 and 2014, the Company reported foreign currency transaction losses of approximately $115,000 and $34,000, respectively .
Cash and Cash Equivalents	Cash and Cash Equivalents The Company invests its excess cash in investment-grade marketable securities, including money market funds, money market securities, corporate bonds, and corporate commercial paper and U.S. government agency bonds. For financial reporting purposes, liquid investment instruments purchased with an original maturity of three months or less are considered to be cash equivalents. Cash and cash equivalents are recorded at face value or cost, which approximates fair market value. From time to time, the Company maintains cash balances in excess of amounts insured by the Federal Deposit Insurance Commission (FDIC). Investments are stated at fair value as determined by quoted market prices. Investments are considered available-for-sale and, accordingly, unrealized gains and losses are included in accumulated other comprehensive income within stockholders’ equity (deficit). The Company’s entire investment portfolio, except for restricted cash, is considered to be available for use in current operations and, accordingly, all such investments are stated at fair value using quoted market prices and classified as current assets, although the stated maturity of individual investments may be one year or more beyond the balance sheet date. The Company did not have any trading securities or restricted investments at September 30, 2015 and December 31, 2014. Realized gains and losses and declines in value, if any, judged to be other-than-temporary or available-for-sale securities, are reported in interest income or expense, net. When securities are sold, any associated unrealized gain or loss previously reported as a separate component of stockholders’ equity is reclassified out of stockholders’ equity and recorded in the statements of operations in the period sold. Accrued interest and dividends are included in interest income. The Company periodically reviews its available-for-sale securities for other-than-temporary declines in fair value below the cost basis, and whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.
Restricted Cash	Restricted Cash The Company has a credit card facility with its primary operating bank which is collateralized by certificates of deposits maintained at the bank
Fair Value Measurements	Fair Value Measurements Assets and liabilities are measured using quoted prices in active markets and total fair value is the published market price per unit multiplied by the number of units held without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are valued by reference to similar assets or liabilities, adjusted for contract restrictions and other terms specific to that asset or liability. For these items, a significant portion of fair value is derived by reference to quoted prices of similar assets or liabilities in active markets. For all remaining assets and liabilities, fair value is derived using a fair value model, such as a discounted cash flow model or Black-Scholes model.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts of accounts receivable, accounts payable, and accrued liabilities are considered to be representative of their respective fair values because of the short-term nature of those instruments. Based on the borrowing rates currently available to the Company for loans with similar terms, the Company believes that the fair value of long-term debt approximates its carrying value. The carrying amount of the warrant liability and non-controlling interest represent their fair values. The valuation of assets and liabilities are subject to fair value measurements using a three-tiered approach and fair value measurements are classified and disclosed by the Company in one of the following three categories: Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; Level 2: Quoted prices for similar assets and liabilities in active markets, quoted prices in markets that are not active, or inputs which are observable, either directly or indirectly, for substantially the full term of the asset or liability; and Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity).
Revenue Recognition	Revenue Recognition The Company recognizes revenue from product sales when the following criteria are met: goods are shipped, title and risk of loss has transferred to its customers, persuasive evidence of an arrangement exists and collectability is reasonably assured. Persuasive evidence of an arrangement exists when there is a contractual arrangement in place with the customer. Delivery has occurred when a product is shipped. If persuasive evidence of an arrangement exists and delivery has occurred, the Company determines whether the invoiced amount is fixed or determinable and collectability of the invoiced amount is reasonably assured. The Company assesses whether the invoiced amount is fixed or determinable based on the existing arrangement with the customer, including whether the Company has sufficient history with a customer to reliably estimate the customer’s payment patterns. The Company assesses collectability by evaluating historical cash receipts and individual customer outstanding balances. To the extent all criteria set forth above are not satisfied at the time of shipment, revenue is recognized when cash is received from the customer. Customers are not granted specific rights of return; however, the Company may permit returns of product from customers if such product is returned in a timely manner and in good condition. The Company provides a warranty on its products for one year from the date of shipment, and any product found to be defective or out of specification will be replaced at no charge during the warranty period. Estimated allowances for sales returns and warranty replacements are recorded at the time of sale of the product and are estimated based upon the historical patterns of product returns matched against sales, and an evaluation of specific factors that may increase the risk of product returns. Product returns and warranty replacements to date have been consistent with amounts reserved or accrued and have not been significant.
Stock Warrants	Stock Warrants The Company has issued freestanding warrants to purchase shares of its common stock, which are accounted for as a liability because they contain a down-round protection provision that is outside the control of the Company. The warrants are recorded on the Company’s balance sheet at their fair value as determined on the date of issuance and are revalued at each subsequent balance sheet date, with fair value changes recognized as other income or expense in the accompanying condensed consolidated statements of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrants. The Company estimates the fair value of the liability using option pricing models and assumptions that are based on the individual characteristics of the warrants or instruments on the valuation date, including assumptions for expected volatility, expected life, yield, and risk-free interest rate.
Research and Development Expenses	Research and Development Expenses Major components of research and development expense include personnel costs, preclinical studies, clinical trials and related clinical product manufacturing, materials and supplies, and fees paid to consultants. Research and development costs are expensed as goods are received or services are rendered. Costs to acquire technologies to be used in research and development that have not reached technological feasibility and have no alternative future use are also expensed as incurred. At each financial reporting date, the Company accrues the estimated costs of clinical study activities performed by third party clinical sites with whom the Company has agreements that provide for fees based upon the quantities of subjects enrolled and clinical evaluation visits that occur over the life of the study. The estimates are determined based upon a review of the agreements and data collected by internal and external clinical personnel as to the status of enrollment and subject visits, and are based upon the facts and circumstances known to the Company at each financial reporting date. If the actual performance of activities varies from the assumptions used in the estimates, the accruals are adjusted accordingly. There have been no material adjustments to the Company’s prior period accrued estimates for clinical trial activities through September 30, 2015 and December 31, 2014. Stock-Based Compensation
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense for all stock-based awards granted to employees and nonemployees, including members of its Board of Directors. The fair value of stock-based awards made to employees is estimated at the grant date using the Black-Scholes option-pricing model, and the portion that is ultimately expected to vest is recognized as compensation cost over the requisite service period using the straight-line method. The determination of the fair value-based measurement of stock options on the date of grant using an option pricing model is affected by the determination of the fair value of the underlying stock as well as assumptions regarding a number of highly complex and subjective variables. These variables include, but are not limited to, the Company’s stock price volatility over the expected term of the grants, and actual and projected employee stock option exercise behaviors. In the future, as additional empirical evidence regarding these estimates becomes available, the Company may change or refine its approach of deriving them, and these changes could impact the fair value-based measurement of stock options granted in the future. Changes in the fair value-based measurement of stock awards could materially impact the Company’s operating results. The fair values of stock-based awards made to nonemployees are remeasured at each reporting period using the Black-Scholes option-pricing model. Compensation expense for these stock-based awards is determined by applying the remeasured fair values to the shares that have vested during a period.
Net Loss Per Share	Net Loss Per Share Basic net loss per share is calculated by dividing the net loss by the weighted average number of common shares that were outstanding for the period, without consideration for common stock equivalents. Diluted net loss per share is calculated by dividing the net loss by the sum of the weighted average number of dilutive common share equivalents outstanding for the period determined using the treasury-stock method. Common stock equivalents are comprised of convertible preferred stock, preferred stock warrants, and stock options outstanding under the Company’s stock option plans. The calculation of diluted net loss per share requires that, to the extent the average fair value of the underlying shares for the reporting period exceeds the exercise price of the warrants and the presumed exercise of such securities are dilutive to net loss per share for the period, adjustments to net loss used in the calculation are required to remove the change in fair value of the warrants for the period. Likewise, adjustments to the denominator are required to reflect the related dilutive shares. The Company’s computation of loss per share is as follows (in thousands, except per share amounts): Three Months Ended Nine Months Ended September 30, September 30, 2015 2014 2015 2014 Numerator: Net loss attributable to Glaukos Corporation - basic $ $ $ $ Adjustment for revaluation of warrants - - - Net loss attributable to Glaukos Corporation - diluted $ $ $ $ Denominator: Weighted average number of common shares oustanding - basic Common stock equivalents from outstanding common stock warrants - - - Weighted average number of common shares oustanding - diluted Basic net loss per share attributable to Glaukos Corporation common stockholders $ $ $ $ Diluted net loss per share attributable to Glaukos Corporation common stockholders $ $ $ $ Potentially dilutive securities not included in the calculation of diluted net loss per share attributable to common stockholders because to do so would be anti-dilutive were as follows (in common stock equivalent shares, in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2015 2014 2015 2014 Convertible preferred stock outstanding - - Preferred stock warrants outstanding - - Common stock warrants outstanding - - Stock options outstanding
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB issued guidance codified in ASC 606, Revenue Recognition — Revenue from Contracts with Customers , which amends the guidance in former ASC 605, Revenue Recognition , which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most current revenue recognition guidance. This ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. In July 2015, the FASB deferred the effective date for annual reporting periods beginning after December 15, 2017 (including interim periods within those periods). Early adoption is permitted to the original effective date of December 15, 2016 (including interim periods within those periods). The Company is currently evaluating the impact of the provisions of ASC 606 on its financial statements. In June 2014, the FASB issued an accounting standards update that requires a performance target that affects vesting of a share-based payment award and that could be achieved after the requisite service period to be treated as a performance condition. As such, the performance target should not be reflected in estimating the grant date fair value of the award. Compensation cost should be recognized over the required service period if it is probable that the performance target will be achieved. This guidance will be effective for fiscal years beginning after December 15, 2015, which will be the Company’s fiscal year 2016, with early adoption permitted. The Company does not expect the adoption of the guidance to have material impact on the Company’s consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern . This ASU introduces an explicit requirement for management to assess if there is substantial doubt about an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. In connection with each annual and interim period, management must assess if there is substantial doubt about an entity’s ability to continue as a going concern within one year after the issuance date. Disclosures are required if conditions give rise to substantial doubt. ASU 2014-15 is effective for all entities in the first annual period ending after December 15, 2016. The Company is currently assessing the potential effects of this ASU on the consolidated financial statements. In February 2015, the FASB issued Accounting Standards Update (ASU) 2015-02, Amendments to the Consolidation Analysis , which eliminates the deferral of FAS 167, which allows reporting entities with interests in certain investment funds to follow the consolidation guidance in FIN 46(R), and make other changes to both the variable interest model and the voting model. The ASU is effective for annual periods beginning after December 15, 2015 and interim periods therein, with early adoption permitted. During the quarter ended June 30, 2015, the Company early adopted the provisions of the ASU effective January 1, 2015. Based on the asset purchase transaction with DOSE on June 30, 2015 and the Company’s evaluation of the modified relationship with DOSE, management determined that after the transaction DOSE is no longer a VIE requiring consolidation (See Note 9). In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330), Simplifying the Measurement of Inventory , which changes the measurement principle for inventory from the lower of cost or market to the lower of cost and net realizable value. ASU 2015-11 defines net realizable value as estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance must be applied on a prospective basis and is effective for fiscal years beginning after December 15, 2015, and interim periods within those years, with early adoption permitted. The Company does not believe the implementation of this standard will have a material impact on its financial statements.
