Basis of Presentation, Significant Accounting Policies and Recently-Issued Accounting Pronouncements | Note 2—Basis of presentation, significant accounting policies and recently-issued accounting pronouncements The accompanying condensed consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. Certain information and disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. Accordingly, these condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K Use of estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual amounts could differ from those estimates. Significant Accounting Policies There have been no material changes in the accounting policies from those disclosed in the audited consolidated financial statements and the related notes included in the Annual Report on Form 10-K. Recently-issued accounting standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace all existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. In July 2015, the FASB voted to defer the effective date to January 1, 2018, with early adoption beginning January 1, 2017. In March, April, May, and December 2016, the FASB issued amendments to the new guidance relating to reporting revenue on a gross versus net basis, identifying performance obligations and licensing arrangements and other narrow scope improvements. The Company will adopt the new revenue guidance in the first quarter of 2018 though has not yet determined whether to adopt using a full retrospective or modified retrospective approach. The Company is currently assessing the impact of the new revenue guidance on its arrangements. The Company currently believes that the new guidance will impact the amount and timing of incremental costs of obtaining a contract, such as sales commissions. The Company generally does not pay sales commissions upon contract renewal and therefore, under the new revenue guidance, the sales commissions will be recognized over an estimated customer life rather than over the non-cancelable In February 2016, the FASB issued new guidance which significantly changes the accounting for leases. The new guidance requires a lessee recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use right-of-use In March 2016, the FASB issued new guidance to simplify various aspects relating to accounting for stock-based compensation and related tax impacts, the classification of excess tax benefits on the statement of cash flows, statutory tax withholding requirements, and other stock-based compensation classification matters. The guidance was effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods. The Company adopted this guidance during the first quarter ended March 31, 2017. Upon adoption, the Company changed an accounting policy to account for forfeitures when they occur rather than estimate a forfeiture rate. The impact of this change in policy increased the Company’s accumulated deficit and additional paid-in In June 2016, the FASB issued guidance which requires that financial assets measured at amortized costs be presented at the net amount expected to be collected. This guidance amends the accounting for credit losses for available-for-sale In November 2016, the FASB issued guidance which requires that restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning and ending total amounts shown on the statement of cash flows. This guidance is effective for fiscal years beginning after December 15, 2017, and interim periods within those years, and should be applied using a retrospective transition method to each period presented. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company’s restricted cash as of March 31, 2017 and December 31, 2016 was $0.4 million and therefore, the adoption of this guidance is not expected to have a material impact on the Company’s consolidated statements of cash flows. In February 2017, the FASB issued guidance which simplifies the subsequent measurement of goodwill by no longer requiring an entity to determine goodwill impairment by calculating the implied fair value of goodwill by assigning the fair value of a reporting unit to all of its assets and liabilities as if that reporting unit had been acquired in a business combination. Under this new guidance, an entity would perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount and would recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized would not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity would consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. Under the new guidance, an entity continues to have the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. This guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those years. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements. In March 2017, the FASB issued guidance which shortens the amortization period for certain purchased callable debt securities held at a premium. Under this new guidance, an entity would shorten the amortization period of the premium to the earliest call date. This guidance is effective for annual periods beginning after December 15, 2018, and interim periods within those annual periods. Early adoption is permitted, including adoption in an interim period. The Company has not determined the impact of this guidance on its consolidated financial statements. | Note 2—Significant accounting policies Principles of consolidation and basis of presentation The Company’s consolidated financial statements are presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and include the operating results of its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Reverse stock split On October 12, 2016, the Company effected a 1-for-5 Use of estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. On an ongoing basis, management evaluates its estimates, primarily those related to determining the best estimate of selling price (“BESP”) for separate deliverables in the Company’s subscription revenue arrangements, vendor-specific objective evidence (“VSOE”) for separate deliverables in the Company’s licensed revenue arrangements, allowance for doubtful accounts, fair value of assets and liabilities assumed in a business combination, recoverability of goodwill and long-lived assets, useful lives associated with long-lived assets, contingencies, fair value of contingent consideration, and the valuation and assumptions underlying stock-based compensation and common stock warrants. These estimates are based on historical data and experience, as well as various other factors that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. Segments Management has determined that the Company has one operating segment. The Company’s chief executive officer, who is the Company’s chief operating decision maker, reviews financial information on a consolidated and aggregate basis, together with certain operating metrics principally to make decisions about how to allocate resources and to measure the Company’s performance. Cash and cash equivalents The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents. Cash includes cash held in checking and savings accounts. Cash equivalents are comprised of investments in money market mutual funds. The carrying value of cash and cash equivalents approximates fair value. Restricted cash Included in non-current Investments in Marketable Securities Our marketable securities consist of commercial paper, corporate bonds, U.S. treasury bonds, and asset-backed securities. The Company classifies its marketable securities as available-for-sale The Company classifies its investments in marketable securities in current assets as the investments are available for use, if needed, in current operations. Investments in marketable securities presented within current assets on the consolidated balance sheet as of December 31, 2016 consisted of the following: Amortized Gross Gross Fair (in thousands) Marketable securities U.S. Treasury bonds $ 29,742 $ — $ (17 ) $ 29,725 Corporate Bonds 25,522 — (21 ) 25,501 Commercial paper 15,554 — — 15,554 Asset-backed securities 12,353 — (3 ) 12,350 $ 83,171 $ — $ (41 ) $ 83,130 Gross realized gains and losses on marketable securities and net gains and losses reclassified from accumulated other comprehensive income to earnings were not material for the year ended December 31, 2016. The Company’s marketable securities have a contractual maturity of less than 4 years. The amortized cost and fair values of marketable securities, by remaining contractual maturity, were as follows: December 31, 2016 Amortized Fair (in thousands) Due in 1 year or less $ 49,371 $ 49,363 Due after 1 year through 4 years 33,800 33,767 $ 83,171 $ 83,130 The Company held no marketable securities during the years ended December 31, 2015 and 2014. Accounts receivable and allowance for doubtful accounts Accounts receivable are recorded at the invoiced amount, do not require collateral and do not bear interest. The Company estimates its allowance for doubtful accounts by evaluating specific accounts where information indicates the Company’s customers may have an inability to meet financial obligations, such as bankruptcy and significantly aged receivables outstanding. Concentration of credit risk and significant customers Financial instruments that potentially subject the Company to a significant concentration of credit risk consist of cash and cash equivalents, investments in marketable securities and accounts receivable. The Company maintains the majority of its cash balances with one major commercial bank in non-interest The Company invests its excess cash in money market mutual funds, commercial paper, corporate bonds, U.S. treasury bonds, and asset-backed securities. To date, the Company has not experienced any impairment losses on its investments. For the years ended December 31, 2016, 2015 and 2014, no single customer comprised 10% or more of the Company’s total revenues. No single customer had an accounts receivable balance of 10% or greater of total accounts receivable at December 31, 2016 and 2015. Property and equipment Property and equipment is stated at cost less accumulated depreciation. Expenditures for repairs and maintenance are expensed as incurred, while renewals and betterments are capitalized. Depreciation expense is charged to operations on a straight-line basis over the estimated useful lives of the assets. The estimated useful lives of the Company’s property and equipment are as follows: Useful Lives Machinery and equipment 3-5 years Purchased software 3-5 Furniture and fixtures 5 years Leasehold improvements Lesser of 7 years or lease term Assets acquired under capital leases are capitalized at the present value of the related lease payments and are amortized over the shorter of the lease term or useful life of the asset. Capitalized internal-use The Company accounts for the costs of computer software obtained or developed for internal use in accordance with ASC 350, Intangibles—Goodwill and Other internal-use During the years ended December 31, 2016, 2015 and 2014, the Company amortized $1.8 million, $0.9 million and $0.3 million, respectively, of internal-use internal-use Business combinations The results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of the acquisition. Purchase accounting results in assets and liabilities of an acquired business generally being recorded at their estimated fair values on the acquisition date. Any excess consideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill. Transaction costs associated with business combinations are expensed as incurred and are included in general and administrative expenses in the consolidated statements of operations. The Company performs valuations of assets acquired and liabilities assumed and allocates the purchase price to its respective assets and liabilities. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates, including the selection of valuation methodologies, estimates of future revenue, costs and cash flows, discount rates, and selection of comparable companies. The Company engages the assistance of valuation specialists in concluding on fair value measurements in connection with determining fair values of assets acquired and liabilities assumed in a business combination. Intangible assets Intangible assets primarily consist of acquired developed technology, customer relationships, trade names and non-compete Useful Lives Trade name 1-10 years Developed technology 6-8 Non-compete 2-5 Customer relationships 8-10 Impairment of long-lived assets Management evaluates the recoverability of the Company’s property and equipment, finite-lived intangible assets and capitalized internal-software costs when events or changes in circumstances indicate a potential impairment exists. Events and changes in circumstances considered by the Company in determining whether the carrying value of long-lived assets may not be recoverable include, but are not limited to, significant changes in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, and changes in the Company’s business strategy. Impairment testing is performed at an asset level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (an “asset group”). In determining if impairment exists, the Company estimates the undiscounted cash flows to be generated from the use and ultimate disposition of the asset group. If impairment is indicated based on a comparison of the assets’ carrying values and the undiscounted cash flows, the impairment loss is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company determined that there were no events or changes in circumstances that potentially indicated that the Company’s long-lived assets were impaired during the years ended December 31, 2016, 2015 and 2014. Goodwill Goodwill represents the excess of the purchase price over the fair value of net assets acquired in a business combination. The Company tests goodwill for impairment in accordance with the provisions of Accounting Standards Codification (“ASC”) 350, Intangibles—Goodwill and Other ASC 350 provides that an entity has the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, an entity determines it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, then additional impairment testing is not required. However, if an entity concludes otherwise, then it is required to perform the first of a two-step The first step involves comparing the estimated fair value of a reporting unit with its book value, including goodwill. If the estimated fair value exceeds book value, goodwill is considered not to be impaired and no additional steps are necessary. If, however, the fair value of the reporting unit is less than book value, then, under the second step, the carrying amount of the goodwill is compared with its implied fair value. The estimate of implied fair value of goodwill may require valuations of certain internally-generated and unrecognized intangible assets. If the carrying amount of goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. The Company has one reporting unit and it tests for goodwill impairment annually during the fourth quarter of the calendar year. At December 31, 2016, the fair value of the Company significantly exceeded the carrying value of its net assets and accordingly goodwill was not impaired. Deferred rent Rent expense is recorded on a straight-line basis over the term of the lease. The difference between rent expense and the cash paid under the lease agreement is recorded as deferred rent. Lease incentives, including tenant improvement allowances, are also recorded as deferred rent and amortized on a straight-line basis over the lease term. Debt issued with warrants to purchase common stock The Company issued warrants to purchase common stock in connection with its former credit facility. These warrants are a liability classified under ASC 815-40, Contracts in Entity’s Own Equity at-market The initial carrying value of the debt was reduced by the fair value of the warrants. The resulting debt discount was amortized to interest expense over the life of the debt on a straight-line basis, which approximates the effective interest method. In November 2016, the Company repaid all outstanding debt and expensed the then-remaining unamortized debt discount to interest expense in the consolidated statements of operations. Fair value of financial instruments ASC 820, Fair Value Measurements Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. ASC 820 describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value, which are the following: Level 1: Quoted prices in active markets for identical or similar assets and liabilities. Level 2: Quoted prices for identical or similar assets and liabilities in markets that are not active or observable inputs other than quoted prices in active markets for identical or similar 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. As of December 31, 2016 and 2015, the carrying values of cash equivalents, accounts receivable, accounts payable, and accrued expenses, approximate fair values due to the short-term nature of such instruments. The following table summarizes the Company’s financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2016 and 2015, by level, within the fair value hierarchy. Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands): December 31, 2016 Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $ 18,936 $ — $ — $ 18,936 Marketable securities U.S. Treasury bonds 29,725 — — 29,725 Corporate bonds — 25,501 — 25,501 Commercial paper — 15,554 — 15,554 Asset-backed securities — 12,350 — 12,350 Total assets $ 48,661 $ 53,405 $ — $ 102,066 Liabilities Common stock warrant liability $ — $ — $ 11,380 $ 11,380 Contingent consideration — — 5,238 5,238 Total liabilities $ — $ — $ 16,618 $ 16,618 December 31, 2015 Level 1 Level 2 Level 3 Total Cash equivalents Money market funds $ 15,990 $ — $ — $ 15,990 Total assets 15,990 $ — $ — $ 15,990 Liabilities Common stock warrant liability $ — $ — $ 5,500 $ 5,500 Contingent consideration — — 4,867 4,867 Total liabilities $ — $ — $ 10,367 $ 10,367 Contingent consideration relating to our 2013 Acquisition (Refer to Note 9) is recorded as a liability and is measured at fair value each period, based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions management believes would be made by a market participant. Management assesses these estimates on an ongoing basis as additional data impacting the assumptions becomes available. Changes in the fair value of contingent consideration related to updated assumptions and estimates are recognized within general and administrative expenses in the consolidated statements of operations. The Company determined the fair value of the contingent consideration by discounting estimated future taxable income. The significant inputs used in the fair value measurement of contingent consideration are the timing and amount of taxable income in any given period and determining an appropriate discount rate, which considers the risk associated with the forecasted taxable income. Significant changes in the estimated future taxable income and the periods in which they are generated would significantly impact the fair value of the contingent consideration liability. Warrants to purchase common stock are liability classified and are measured at fair value each period. The fair value is determined using a binomial lattice valuation model. The fair value includes significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The valuation of common stock warrants uses assumptions management believes would be made by a market participant. Management assesses these estimates on an ongoing basis as additional data impacting the assumptions becomes available. Changes in the fair value of the common stock warrant liability related to updated assumptions and estimates are recognized within other income (expense), net in the consolidated statements of operations. The significant inputs used in the fair value measurement of the common stock warrants are the estimated fair value of the Company’s common stock and, to a lesser extent, the expected stock volatility, the probability of a change in control and future stock issuances, which impact the term of the warrants. Significant increases or decreases in the estimated fair value of the Company’s common stock would significantly impact the fair value of the warrant liability. The following table summarizes the changes in the common stock warrant liability and contingent consideration liability (in thousands): Contingent Common Fair value as of December 31, 2013 $ 5,607 $ 1,380 Change in fair value (781 ) 3,700 Fair value as of December 31, 2014 4,826 5,080 Change in fair value 41 420 Fair value as of December 31, 2015 4,867 5,500 Change in fair value 371 5,880 Fair value as of December 31, 2016 $ 5,238 $ 11,380 Certain assets, including goodwill and long-lived assets, are also subject to measurement at fair value on a non-recurring non-recurring Revenue recognition The Company derives its revenue from the following sources: Subscription and support revenue — one-year Professional services time-and-material time-and-material The Company recognizes subscription and professional services revenues when (i) persuasive evidence of an arrangement for the sale of the Company’s solutions or consulting services exists, (ii) the solutions have been made available or delivered, or services have been performed, (iii) the sales price is fixed or determinable, and (iv) collectability is reasonably assured. The timing and amount the Company recognizes as revenue is determined based on the facts and circumstances of each customer’s arrangement. Evidence of an arrangement consists of a signed customer agreement. The Company considers that delivery of a solution has commenced once it provides the customer with log-in The majority of customer arrangements include multiple deliverables, such as subscriptions to the Company’s SaaS solutions and professional services. The Company recognizes revenue in accordance with the guidance for arrangements with multiple deliverables under Accounting Standards Update (“ASU”) 2009-13, Revenue Recognition (Topic 605)—Multiple-Deliverable Revenue Arrangements—a Consensus of the Emerging Issues Task Force 985-605, Software non-performance For multiple-deliverable revenue arrangements, the Company first assesses whether each deliverable has value to the customer on a standalone basis. The Company has determined that the SaaS products have standalone value because, once access is given to the customer, the solutions are fully functional and do not require any additional development, modification or customization. Professional services have standalone value because third-party partners and customers themselves can perform these services without the Company’s involvement. The performance of these professional services generally does not require highly specialized or technologically skilled individuals and the professional services are not essential to the functionality of the solutions. The Company allocates revenue among the separate non-contingent 2009-13. The Company is not able to determine VSOE or TPE for its deliverables because the deliverables are typically bundled and infrequently sold separately within a consistent price range. Additionally, management has determined that there are no third-party offerings reasonably comparable to the Company’s solutions. Therefore, the selling prices of subscriptions to the SaaS solutions and professional services are based on BESP. The determination of BESP requires the Company to make significant estimates and judgments. The Company considers numerous factors, including the nature of the deliverables themselves, geography, customer size and number of users, and discounting practices. The determination of BESP is made through consultation with senior management. The Company updates its estimates of BESP on an ongoing basis as events and circumstances may require. As the Company’s marketing strategies evolve, the Company may modify its pricing practices in the future, which could result in changes in relative selling prices and BESP. The Company uses business process outsourcers (“BPOs”) and resellers to complement its direct sales and marketing efforts. The BPOs and resellers place orders with the Company after receiving an order from an end customer. The BPOs and resellers receive business terms of sale similar to those received by the Company’s direct customers, and payment to the Company is not contingent on the receipt of payment from the end customer. The BPOs and resellers negotiate pricing with the end customer and are responsible for implementation services, if any, and for certain support levels directly with the end customer. The Company recognizes revenue over the term of the arrangement for the contractual amount charged to the BPO or reseller once access to the Company’s solution has been provided to the end customer provided that the other revenue recognition criteria noted above have been met. Subscription and support revenues also include revenues associated with sales of software licenses and related support. Prior to the development of the Company’s SaaS solutions, the Company sold software licenses and post contract support related to its legacy software in accordance with ASC 985-605. On August 31, 2016, the Company acquired Runbook, a Netherlands-based provider of licensed financial close automation software and integration for SAP customers. The Company plans to migrate Runbook’s licensed products to a cloud-based platform, but the Company continues to sell Runbook’s on-premise Revenues recognized from sales of software licenses, support and implementation services related to software arrangements comprised approximately 1%, 1% and 3% of total revenues for the years ended December 31, 2016, 2015 and 2014, respectively. Taxes collected from customers are accounted for on a net basis and are excluded from revenue. Cost of revenues Cost of revenues primarily consists of costs related to hosting the Company’s cloud-based application suite, salaries and benefits of operations and support personnel, including stock-based compensation, and amortization of capitalized internal-use Sales and marketing Sales and marketing expenses consist primarily of compensation and employee benefits, including stock-based compensation, of sales and marketing personnel and related sales support teams, sales and partner commissions, marketing events, advertising costs, travel, trade shows, other marketing materials, and allocated overhead. Sales and marketing expenses also include amortization of customer relationship intangible assets. Advertising costs are expensed as incurred and totaled $4.2 million, $3.0 million and $1.5 million for the years ended December 31, 2016, 2015 and 2014, respectively. Deferred sales commissions Deferred sales commissions are the incremental costs that are directly associated with non-cancelable non-cancelable non-cancelable non-cancelable Research and development Research and development expenses are comprised primarily of salaries, benefits and stock-based compensation associated with the Company’s engineering, product and quality assurance personnel. Research and development expenses also include third-party contractors and supplies and allocated overhead. Other than software development costs that qualify for capitalization, as discussed above, research and development costs are expensed as incurred. General and administrative General and administrative expenses consist primarily of personnel costs associated with the Company’s executive, finance, legal, human resources, compliance, and other administrative personnel, as well as accounting and legal professional services fees, other corporate-related expenses and allocated overhead. General and administrative expenses also include amortization of covenant not to compete and tradename intangible assets, the change in value of the contingent consideration and acquisition-related costs of business combinations. Stock-based compensation The Company accounts for stock-based compensation awards granted to employees and directors based on the awards’ estimated grant date fair value. The Company estimates the fair value of its stock options using the Black-Scholes option-pricing model. For awards that vest solely based on continued service (“service-only vesting conditions”), the resulting fair value, net of estimated forfeitures, is recognized on a straight-line basis over the period during which an employee is required to provide service in exchange for the award, usually the vesting period, which is generally four years. The Company recognizes the fair value of stock options which contain performance conditions based upon the probability of the performance conditions being met, net of estimated forfeitures, using the graded vesting method. Estimated forfeitures are based upon the Company’s historical experience and the Company revises its estimates, if necessary, in subsequent periods if actual forfeitures differ from initial estimates. Determining the grant date fair value of options using the Black-Scholes option-pricing model requires management to make assumptions and judgments. These estimates involve inherent uncertainties and, if different assumptions had been used, stock-based compensation expense could have been materially different from the amounts recorded. The assumptions and estimates are as follows: Value per share of the Company’s common stock. Expected volatility. Expected term. mid-point Risk-free interest rate. Estimated dividend yield. The following information represents the weighted average of the assumptions used in Black-Scholes option-pricing model: Year ended December 31, 2016 2015 2014 Expected term (years) 6.3 6.3 6.2 Expected volatility 47.5 % 49.6 % 54.0 % Risk free interest rate 1.4 % 1.7 % 1.9 % Expected dividends — — — Income taxes The Company accounts for income taxes in accordance with ASC 740, Income Taxes The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized. The Company recognizes interest and penalties accrued with respect to uncertain tax positions, if any, in the provision for income taxes in the consolidated statements of operations. Net loss per share Basic and diluted loss per share is calculated by dividing net loss by the weighted average number of shares of common stock outstanding. As the Company has net losses for the periods presented, all potentially dilutive common stock, which are comprised of stock options and warrants, are antidilutive. As of December 31, 2016 and 2015, the following potentially dilutive shares have been excluded from the calculation of diluted net loss per share attributable to common stockholders because they are anti-dilutive: December 31, 2016 2015 Options to purchase common stock 6,556,986 5,904,376 Common stock warrants 499,999 499,999 Total shares excluded from net loss per share 7,056,985 6,404,375 Foreign currency The Company’s foreign subsidiaries’ functional currency is the U.S. Dollar. The foreign exchange impacts of remeasuring the foreign subsidiaries’ local currency to the U.S. Dollar functional currency is recorded in general and administrative expenses, net in the Company’s consolidated statements of operations. Monetary assets and liabilities of foreign operations are remeasured at balance sheet date exchange rates, non-monetary Recently issued accounting standards Under the Jumpstart Our Business Startups Act, or the JOBS Act, the Company meets the definition of an emerging growth company. The Company has irrevocably elected to opt out of the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act. In May 2014, the Financial Accounting Standards Board (“FASB”) issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace all existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. In July 2015, the FASB voted to defer the effective date to January 1, 2018, with early adoption beginning January 1, 2017. In March, April, May, and December 2016, the FASB issued amendments to the new guidance relating to reporting revenue on a gross versus net basis, identifying performance obligations and licensing arrangements and other narrow scope improvements. The Company will adopt the new revenue guidance in the first quarter of 2018 though has not yet determined whether to adopt using a full retrospective or modified retrospective approach. The Company is currently assessing the impact of the new revenue guidance on its arrangements. The Company currently believes that the new guidance will impact the amount and timing of incremental costs of obtaining a contract, such as sales commissions. The Company generally does not pay sales commissions upon contract renewal and therefore, under the new revenue guidance, the sales commissions will be recognized over an estimated customer life rather than over the non-cancelable In February 2016, the FASB issued new guidance which significantly changes the accounting for leases. The new guidance requires a lessee recognize in the balance sheet a liability to make lease payments (the lease liability) and a right-of-use right-of-use In March 2016, the FASB issued new guidance to simplify various aspects relating to accounting for stock-based compensation and related tax impacts, the classification of excess tax benefits on the statement of cash flows, statutory tax withholding requirements and other stock-based compensation classification matters. The guidance is effective for annual reporting periods beginning after December 15, 2016 and interim periods within those annual periods. Early adoption was permitted in any interim or annual period. All of the amendments in the new guidance must be adopted in the same period. The Company is required to adopt this guidance during the first quarter ending March 31, 2017. The Company expects to adopt a policy to account for forfeitures when they occur rather than estimate a forfeiture rate.
