Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. Revenue Recognition The Company primarily derives its revenues from subscription fees and related services, permitting customers to access and utilize the Company’s cloud-based business automation solutions for spend management. Customers may also purchase a perpetual license for certain software products. Revenue is recognized when there is persuasive evidence of an arrangement, the service has been provided or delivered to the customer, the collection of the fee is probable and the amount of the fee to be paid by the customer is fixed or determinable. The Company’s arrangements do not contain general rights of return. Because customers do not have the right to take possession of the Software-as-a-Service (“SaaS”) based software, these arrangements are considered service contracts and are not within the scope of Industry Topic 985 , Software. Revenue Recognition for Multiple-Element Arrangements For arrangements in which elements do have stand-alone value, the Company allocates revenue to each element in the arrangement based on a selling price hierarchy. The selling price for a deliverable is based on vendor-specific objective evidence of selling price (“VSOE”), if available, third-party evidence of selling price (“TPE”), if VSOE is not available, or estimated selling price (“ESP”) if neither VSOE nor TPE is available. Because the Company has neither VSOE nor TPE for its deliverables, the allocation of revenue is based on ESP. The Company’s process for determining ESP for its deliverables considers multiple factors that may vary depending upon the facts and circumstances related to each deliverable. Key factors considered in developing ESP related to deliverables include established pricing and approval policies, type and size of customer, number of products purchased, and historical transactions. The Company regularly reviews ESP and maintains internal controls over the establishment and updates of these estimates. The Company evaluates its SaaS subscription agreements and considers whether the associated services have standalone value to its customers. For arrangements when implementation services do not have standalone value to the customer, licenses and related implementation services are considered a single unit of accounting. Accordingly, the consideration allocated to licenses and services is recognized ratably over the term of the subscription agreement, beginning with the later of the start date specified in the subscription agreement, or the date access to the software is provided to the customer, provided all other revenue recognition criteria have been met. Fees for professional services that are contingent upon future performance are recognized ratably over the remaining subscription term once the performance milestones have been met. Alternatively, when services have standalone value to the customer, licenses and related services are considered separate units of accounting. For separate units of accounting, services are recognized as the services are performed and delivered to the customer and licenses are recognized over the term of the subscription arrangement, beginning with the later of the start date specified in the subscription agreement, or the date access to the software is provided to the customer, provided all other revenue recognition criteria have been met. Revenue from sales of certain of the Company’s perpetual software products and related implementation services and maintenance is recognized as a single unit of accounting since VSOE of fair value does not exist for the contractual elements. Accordingly, revenue for all elements in these arrangements is recognized over the contractual maintenance term, which is typically one year. The Company recognizes revenue from any professional services that are sold separately as the services are performed. Sales taxes collected from customers and remitted to government authorities are excluded from revenue. Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from the Company’s software and services described above. For multi-year subscription agreements, the Company generally invoices its customers in annual installments. Accordingly, the deferred revenue balance does not represent the total contract value of these multi-year subscription agreements. The Company’s services, such as implementation, are generally sold in conjunction with subscription agreements. These services are recognized ratably over the remaining term of the subscription agreement once any contingent performance milestones have been satisfied. The portion of deferred revenue that the Company anticipates will be recognized after the succeeding 12-month period is recorded as non-current deferred revenue and the remaining portion is recorded as current deferred revenue. Cost of Revenues Cost of revenues primarily consists of costs related to hosting the Company’s subscription software services, compensation and related expenses for implementation services, supplier enablement services, customer support staff and client partners, amortization of capitalized software development costs and allocated fixed asset depreciation and facilities costs. Cost of revenues is expensed as incurred. Deferred Commissions The Company capitalizes sales commission costs that are directly related to the execution of its subscription agreements. The commissions are deferred and amortized over the contractual term of the related non-cancelable subscription agreement. The Company believes this is the appropriate method of accounting, as the commission costs are so closely related to the revenues from the subscription agreements that they should be recorded as an asset and charged to expense over the same period that the subscription revenues are recognized. Amortization of deferred commissions is included in sales and marketing expense in the accompanying consolidated statements of operations and comprehensive loss. Concentrations As of December 31, 2015 and 2014, no individual customer comprised more than 10% of the accounts receivable balance. During each of the years ended December 31, 2015, 2014 and 2013, no individual customer comprised more than 10% of the Company’s revenues. During the year’s ended December 31, 2015, 2014 and 2013, approximately 88%, 87% and 89%, respectively, of the Company’s revenue was from sales transactions originating in the United States. As of December 31, 2015 and 2014, all of the Company’s long-lived assets were located in North America. Cash and Cash Equivalents The Company considers all highly liquid debt investments with an original maturity of three months or less at the date of purchase to be cash equivalents. The Company maintains cash balances at financial institutions that may at times exceed federally insured limits. The Company maintains this cash at reputable financial institutions and, as a result, believes credit risk related to its cash is minimal. Short-Term Investments Management determines the appropriate classification of investments at the time of purchase and evaluates such determination as of each balance sheet date. The Company’s investments were classified as available-for-sale securities and are stated at fair value at December 31, 2015 and 2014. Realized gains and losses are included in other income based on the specific identification method. There were no realized gains or losses for the years ended December 31, 2015, 2014 or 2013. Net unrealized gains and losses on available-for-sale securities are reported as a component of other comprehensive loss, net of tax. As of December 31, 2015 and 2014, there were no unrealized gains or losses on available-for-sale securities. The Company regularly monitors and evaluates the fair value of its investments to identify other-than-temporary declines in value. Management believes no such declines in value existed at December 31, 2015 or 2014. Accounts Receivable The Company assesses the need for an allowance for doubtful accounts based on estimates of probable credit losses. This assessment is based on several factors including aging of customer accounts, known customer specific risks, historical experience and existing economic conditions. The Company generally does not require collateral for receivable balances. Accounts would be charged against the allowance after all means of collection were exhausted and recovery was considered remote. Based on management’s analysis of its outstanding accounts receivable, the Company recorded an allowance of $473 and $1,100 at December 31, 2015 and 2014, respectively. Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives, which are usually seven years for furniture and three to five years for computer software and equipment. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the remainder of the lease term. Costs for repairs and maintenance are expensed as incurred. Upon retirement or sale, the cost of the disposed assets and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is credited or charged to operations. Software Development Costs The Company incurs certain costs associated with the development of its cloud-based solution, which are accounted for as internal-use software. Certain qualifying costs incurred during the application development phase are capitalized and amortized to expense over the estimated useful life of the related applications, which is generally three years. Goodwill Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. Additionally, the Company would also review the carrying value of goodwill whenever events or changes in circumstances indicated that its carrying amount may not be recoverable. The Company has concluded that it has one reporting unit for purposes of its annual goodwill impairment testing. To assess goodwill impairment, the first step is to identify if a potential impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered to have a potential impairment and the second step of the impairment test is not necessary. The Company performed its annual assessments on December 31, 2015 and 2014. The estimated fair value of the Company’s reporting unit exceeded its carrying amount, including goodwill, and as such, no goodwill impairment was recorded. Long-Lived Assets The Company evaluates the recoverability of its property and equipment and other long-lived assets, including acquired technology and customer relationships, when events change or circumstances indicate the carrying amount may not be recoverable. If such events or changes in circumstances are present, the undiscounted cash flow method is used to determine whether the asset is impaired. An impairment loss is recognized when, and to the extent, the net book value of such assets exceeds the fair value of the assets or the business to which the assets relate. Cash flows would include the estimated terminal value of the asset and exclude any interest charges. The discount rate utilized would be based on the Company’s best estimate of the related risks and return at the time the impairment assessment is made. There were no impairments losses recognized related to the Company’s long-lived assets during the years ended December 31, 2015, 2014, and 2013. Sales and Marketing Expenses Sales and marketing expenses consist primarily of costs, including salaries and sales commissions, of all personnel involved in the sales process. Sales and marketing expenses also include costs of advertising, trade shows, certain indirect costs and allocated fixed asset depreciation and facilities costs. Advertising costs are expensed as incurred. Advertising expenses totaled approximately $646, $883 and $678 for the years ended December 31, 2015, 2014 and 2013, respectively. Stock-Based Compensation Stock-based payments to employees, including grants of employee stock options, are recognized in the consolidated statement of operations and comprehensive loss based on their fair values. Stock-based compensation costs are measured at the grant date based on the fair value of the award and are recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes option-pricing model on the date of grant for stock options and a lattice model on the date of grant for performance-based restricted stock units. Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, forfeiture rates and expected term. The Company uses the historical volatility of its stock price to calculate the expected volatility. Prior to the second half of 2013, the expected volatility rates were estimated based on the actual volatility of comparable public companies over the expected term. The expected term for the years ended December 31, 2015, 2014 and 2013, represents the average time that options that vest are expected to be outstanding based on the mid-point between the vesting date and the end of the contractual term of the award. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards. Foreign Currency and Operations The reporting currency for all periods presented is the U.S. dollar. The functional currency for the Company’s foreign subsidiaries is generally their local currency. The translation of each subsidiary’s financial statements into U.S. dollars is performed for assets and liabilities using exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. The resulting translation adjustments are recognized in accumulated other comprehensive loss, a separate component of stockholders’ equity. At December 31, 2015 and 2014, accumulated other comprehensive loss was $(6,055) and $(3,055), respectively, which is predominantly due to the intercompany balance with the Company’s Canadian subsidiary not expected to be settled in the foreseeable future and the goodwill balance on the Company’s Canadian subsidiary. Realized foreign currency transaction gains and losses are included in the other income section of the consolidated statements of operations and comprehensive loss. Income ( Loss) Per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding for the period. Outstanding unvested restricted stock purchased by employees is subject to repurchase by the Company and therefore is not included in the calculation of the weighted-average shares outstanding until vested. Diluted net income (loss) per share is computed giving effect to all potentially dilutive common stock, including options and restricted stock. The dilutive effect of outstanding awards is reflected in diluted earnings per share by application of the treasury stock method. The following summarizes the calculation of basic and diluted net income (loss) per share: Year Ended December 31, 2015 2014 2013 Basic: Net income (loss) $ 1,862 $ (69 ) $ (4,734 ) Weighted average common shares, basic 27,721 26,609 23,044 Basic net income (loss) per share $ 0.07 $ (0.00 ) $ (0.20 ) Diluted: Net income (loss) $ 1,862 $ (69 ) $ (4,734 ) Weighted average common shares, basic 27,721 26,609 23,044 Dilutive effect of: Options to purchase common stock 122 - - Nonvested shares of restricted stock 34 - - Shares of employee stock purchase plan 12 - - Weighted average common shares, diluted 27,889 26,609 23,044 Diluted net income (loss) per share $ 0.07 $ (0.00 ) $ (0.20 ) The following equity instruments have been excluded from diluted net income (loss) per common share as they would be anti-dilutive. Year Ended December 31, 2015 2014 2013 Common stock options 602 373 77 For the years ended December 2014 and 2013, the Company incurred net losses and, therefore, the effect of the Company’s outstanding stock options, nonvested restricted stock and common stock issuable pursuant to the employee stock purchase plan was not included in the calculation of diluted net loss per share as the effect would be anti-dilutive. For the years ended December 31, 2014 and 2013, diluted net loss per share excluded the impact of 361 and 430 outstanding stock options, 13 and 28 nonvested shares of restricted stock, and approximately 18 shares of common stock issuable Segment Data The Company manages its operations on a consolidated basis for purposes of assessing performance and making operating decisions. Accordingly, the Company has determined that it has a single reporting segment. Income Taxes Deferred income taxes are provided using tax rates enacted for periods of expected reversal on all temporary differences. Temporary differences relate to differences between the book and tax basis of assets and liabilities, principally intangible assets, property and equipment, deferred subscription revenues, accruals and stock-based compensation. Valuation allowances are established to reduce deferred tax assets to the amount that will more likely than not be realized. To the extent that a determination is made to establish or adjust a valuation allowance, the expense or benefit is recorded in the period in which the determination is made. Judgment is required in determining the provision for income taxes. Additionally, the income tax provision is based on calculations and assumptions that are subject to examination by many different tax authorities and to changes in tax law and rates in many jurisdictions. The Company would adjust its income tax provision in the period in which it becomes probable that actual results differ from management estimates. The Company accounts for uncertain tax positions by recognizing and measuring tax benefits taken or expected to be taken on a tax return. A tax benefit from an uncertain position may be recognized only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’s widely understood administrative practices and precedents. If the recognition threshold is met, only the portion of the tax benefit that is greater than fifty percent likely to be realized upon settlement with a taxing authority is recorded. The tax benefit that is not recorded is considered an unrecognized tax benefit. Interest and penalties related to uncertain tax positions are recognized as a component of income tax expense. Recent Accounting Pronouncements In November 2015, the FASB issued new guidance related to balance sheet classification of deferred taxes. The new guidance requires that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. We early adopted this guidance during the year ended December 31, 2015. The retrospective application of this guidance decreased Current assets by $400 and increased Other assets by $400 to include the current portion of the deferred tax assets within the non-current portion of the deferred tax assets in the consolidated Balance Sheet as of December 31, 2014. In August 2014, the FASB issued new accounting guidance which addresses management’s responsibility to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. This guidance is effective for the fiscal year ending after December 15, 2016, and for fiscal years and interim periods thereafter. Early adoption is permitted. The Company does not expect to early adopt this guidance and does not believe that the adoption of this guidance will have a material impact on its financial statements. In May 2014, the FASB issued new accounting guidance on revenue recognition, which provides for a single five-step model to be applied to all revenue contracts with customers. The new standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. Companies have an option to use either a retrospective approach or cumulative effect adjustment approach to implement the standard. The new standard was originally effective for fiscal years and interim periods within those years beginning after December 15, 2016 and early adoption was not permitted. In August 2015, the FASB approved a one year delay of the effective date to reporting periods beginning after December 15, 2017, while permitting companies to voluntarily adopt the new standard as of the original effective date. The Company will adopt this standard in the first quarter of 2018. The Company is currently evaluating the impact that the implementation of this standard will have on its financial statements.

Business Combinations [Abstract]
Business Combinations	3. Business Combinations CombineNet On August 30, 2013, the Company acquired all of the outstanding capital stock of CombineNet, Inc. (“CombineNet”), a leading provider of advanced sourcing software. The acquisition of CombineNet expands the Company’s strategic sourcing footprint with an advanced, cloud-based tool that improves procurement decisions for spend categories that are typically beyond the capabilities of traditional eSourcing software. The purchase price consisted of approximately $26,575 in cash and 820 shares of the Company’s common stock at a fair value of $17,055. The purchase price was subject to an adjustment based on the closing amount of working capital of CombineNet and accordingly as a result of this adjustment, the Company paid an additional $59 in cash and issued approximately 1 shares of common stock at a fair value of $38. The purchase price included $2,465 in cash and 76 shares of common stock that were deposited in escrow to satisfy potential indemnification claims. The Company incurred acquisition costs of approximately $431 during the year ended December 31, 2013, which are included in general and administrative expense in the consolidated statements of operations and comprehensive loss. The acquisition was accounted for under the purchase method of accounting. The operating results of CombineNet are included in the accompanying consolidated financial statements from the date of acquisition. The purchase consideration consisted of the following: Cash $ 26,634 Fair value of common stock 17,093 Total purchase consideration 43,727 Cash acquired 1,042 Net purchase consideration $ 42,685 The purchase price was allocated to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. Acquired technology, trademarks and the covenant not to compete are amortized on a straight-line basis over their respective estimated useful lives. Acquired customer relationships are amortized over a fifteen-year estimated life in a pattern consistent with which the economic benefit is expected to be realized. The excess of the purchase price over the net tangible and identifiable intangible assets acquired was recorded as goodwill, which is not deductible for tax purposes. This asset is attributed to a trained workforce and buyer-specific value resulting from synergies that are not included in the fair values of assets. The allocation of the purchase price as of the acquisition date was as follows: Estimated Estimated Useful Life Fair Value Accounts receivable $ 2,679 Prepaid expenses and other current assets 334 Property and equipment 464 Deferred project costs 121 Deferred tax assets 4,606 Other assets 30 Covenant not to compete 2 years 100 Trademarks 3 years 300 Acquired technology 7 years 4,100 Customer relationships 15 years 13,000 Goodwill 28,624 Accounts payable (98 ) Accrued expenses (786 ) Deferred tax liability (6,349 ) Deferred revenues (4,440 ) Total purchase consideration $ 42,685 The measurement period for the acquisition purchase accounting was closed December 31, 2013. The following unaudited pro forma consolidated results of operations for the year ended December 31, 2013 assumes that the CombineNet acquisition occurred at the beginning of 2013. The unaudited pro forma information combines the historical results for the Company with the historical results for CombineNet for the same period. The unaudited pro forma financial information includes amortization of acquired intangible assets of $2,228 for the year ended December 31, 2013, and includes the fair value adjustment for deferred revenue of $2,366 for the year ended December 31, 2013. The following unaudited pro forma information is not intended to be indicative of future operating results. Year Ended December 31, 2013 Pro forma revenue $ 100,688 Pro forma net loss $ (3,536 ) Pro forma net loss per share, basic $ (0.15 ) Pro forma net loss per share, diluted $ (0.15 ) Spend Radar On October 1, 2012, the Company completed the acquisition of substantially all of the assets of Spend Radar LLC (“Spend Radar”), a leading provider of spend analysis solutions. The acquisition of Spend Radar added cloud-based software for cleansing and classifying spend data to drive and measure cost savings to the Company’s existing business automation solutions for spend management. The purchase price consisted of $8,000 in cash and 113 shares of the Company’s common stock at a fair value of $2,087. The purchase agreement also contained an earnout provision for up to $6,000 in cash and 85 shares of the Company’s common stock based on the successful achievement of certain performance targets and continued employment with the Company from the closing date to December 31, 2013.

The cash earn-out was recognized as compensation expense in the consolidated statement of operations and comprehensive loss in the period in which it was earned. The fair value of the shares under the stock earn-out was recognized as stock-based compensation expense in the consolidated statement of operations and comprehensive loss over the requisite service period of the award. During the year ended December 31, 2013, the Company recognized compensation expense of $4,800, and stock-based compensation expense of $1,252, related to this earn-out arrangement.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements Under GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. GAAP also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are obtained from independent sources and can be validated by a third party, whereas unobservable inputs reflect assumptions regarding what a third party would use in pricing an asset or liability. The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows: — Level 1 — Valuations based on quoted prices in active markets for identical instruments that the Company is able to access. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. — Level 2 — Valuations based on quoted prices in active markets for instruments that are similar, or quoted prices in markets that are not active for identical or similar instruments, and model-derived valuations in which all significant input and significant value drivers are observable in active markets. — Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement. The financial assets for which the Company performs recurring fair value remeasurements are cash equivalents and short-term investments. As of December 31, 2015 and 2014, the Company had cash equivalents of $60,714 and $48,469, respectively, which consist of money market accounts and commercial paper. As of December 31, 2015 and 2014, the Company had short-term investments of $74,612 and $71,493, respectively, which consist of commercial paper and variable rate demand notes that are invested in corporate and municipal bonds. These commercial paper investments have maturities between one and nine months whereas the variable rate demand notes have final maturities between 2025 and 2042, but are puttable by the Company at any time with seven days notice. These cash equivalents and short-term investments are classified within Level 1 of the fair value hierarchy since they are valued using quoted market prices. As of December 31, 2015 and 2014, the Company did not have any financial assets or liabilities with observable inputs not quoted on active markets (Level 2), or without observable market values that would require a high level of judgment to determine fair value (Level 3). The fair value measurements of the Company’s financial assets at December 31, 2015 are as follows: Total Level 1 Level 2 Level 3 Cash equivalents $ 60,714 $ 60,714 $ - $ - Short-term investments 74,612 74,612 - - Total $ 135,326 $ 135,326 $ - $ - Total Level 1 Level 2 Level 3 Cash equivalents $ 48,469 $ 48,469 $ - $ - Short-term investments 71,493 71,493 - - Total $ 119,962 $ 119,962 $ - $ -

Stockholders' Equity	10. Stockholders’ Equity Preferred Stock The Company is authorized to issue up to 5,000 shares of $0.001 par value preferred stock, of which 222 shares are designated as Series A redeemable preferred stock. The Company’s Board of Directors has the authority to issue up to 4,778 shares of preferred stock in one or more series and to fix the designations, rights, preferences and privileges and any qualifications, limitations or restrictions of the shares of each such series of preferred stock, including dividend rights and rates, conversion rights, voting rights, terms of redemption including price and sinking fund provisions, liquidation preferences and number of shares constituting any series or the designation of that series. As of December 31, 2015 and 2014, no shares of preferred stock were issued or outstanding. Stock Incentive Plan The Company’s 2013 Stock Incentive Plan (the “Plan”) allows the Company to grant common stock options, stock appreciation rights, restricted stock units, including performance-based restricted stock units, and restricted stock awards to employees, board members and others who contribute materially to the success of the Company. The Company reserved 3,500 shares of its common stock for issuance under the Plan. Additionally, per the terms of the Plan, shares of common stock previously reserved for issuance under the 2004 Stock Incentive Plan (the “Prior Plan”) as well as shares reserved for outstanding awards under the Prior Plan for which the awards are canceled, forfeited, repurchased or otherwise result in common stock not being issued will be added to the number of shares available for issuance under the Plan. Restricted stock units, including performance-based restricted stock units, and restricted stock awards that are granted shall count towards the total number of shares reserved for issuance under the Plan as 1.65 shares. As of December 31, 2015, 2,541 shares of common stock were available for issuance under the Plan. The following table summarizes the number of shares outstanding and the number of shares available for future grant under the stock incentive plan at December 31, 2015: December 31, 2015 Number of shares reserved under the 2013 Plan 3,500 Number of shares remaining for future grants transferred from Prior Plan 1,070 Number of stock options outstanding under the 2013 Plan (1,503 ) Weighted average exercise price under the 2013 Plan $ 17.49 Weighted average term (in years) 8.9 Number of restricted stock units issued under the 2013 Plan (526 ) Number of shares remaining for future grants SciQuest, Inc. 2013 Stock Incentive Plan 2,541 The Company’s Board of Directors approves the terms of stock options granted. Individual option grants generally become exercisable ratably over a period of four years from the grant date. The contractual term of the options is approximately ten years from the date of grant. The Company recognizes compensation expense associated with restricted stock and common stock options based on the grant-date fair value of the award on a straight-line basis over the requisite service period of the individual grantees, which generally equals the vesting period. Restricted Stock Units and Performance-Based Restricted Stock Units The Company issues restricted stock units and performance-based restricted stock units to certain employees and non-employee directors. Restricted stock units differ from restricted stock awards in that restricted stock units represent the right to receive shares of common stock once such shares are vested and issuable in accordance with the terms of the restricted stock units. Once issued, such shares are not subject to further restrictions. Performance-based restricted stock units differ from restricted stock units in that the number of shares of common stock issuable under performance-based restricted stock units is variable based on over- or under- performance of the Company’s stock price over a specified period of time. Stock-based compensation expense related to these restricted stock units and performance-based restricted stock units is recognized in the consolidated statements of operations and comprehensive loss based on the fair value of these awards. For restricted stock units, the fair value of the awards is the grant date market value of the Company’s common stock. For performance-based restricted stock units, the fair value of the awards is estimated using a lattice model with a volatility assumption based on the vesting period of the awards. Stock-based compensation expense of $1,307, $701, and $500 was recorded during the years ended December 31, 2015, 2014, and 2013, respectively, in connection with these awards. The total unrecognized compensation cost related to these awards is approximately $3,133 at December 31, 2015. This amount is expected to be recognized over a weighted-average period of 2.6 years. The following summarizes the activity of restricted stock units for the years ended December 31, 2015, 2014 and 2013: Weighted- Number of Average Grant Shares Date Fair Value Nonvested as of December 31, 2012 28 15.67 Issued 53 $ 17.87 Vested (28 ) 15.67 Forfeited (4 ) 16.30 Nonvested as of December 31, 2013 49 18.02 Issued 58 24.71 Vested (21 ) 20.24 Forfeited (3 ) 16.30 Nonvested as of December 31, 2014 83 22.20 Issued 305 13.88 Vested (35 ) 22.49 Forfeited (49 ) 16.04 Nonvested as of December 31, 2015 304 $ 14.80 Additionally, the Company previously issued restricted shares of its common stock to certain employees under the Prior Plan. These awards are recognized in the consolidated statements of operations and comprehensive loss based on their fair values. Stock-based compensation expense of $41 was recorded during the year ended December 31, 2013, in connection with these restricted stock awards. As of December 31, 2013, these awards were fully vested. Stock Options The Company also issues common stock options. The following summarizes stock option activity for the year ended December 31, 2015: Weighted- Average Weighted- Remaining Aggregate Number of Average Contractual Intrinsic Value Options Exercise Price Term (In Years) as of Balance outstanding as of December 31, 2014 2,220 $ 17.56 7.5 $ 2,389 Options granted 981 12.79 Options exercised (204 ) 7.53 Options cancelled (438 ) 19.19 Balance outstanding as of December 31, 2015 2,559 $ 16.26 7.6 $ 1,945 Vested and expected to vest at December 31, 2015 2,311 $ 16.31 7.4 $ 1,804 Exercisable as of December 31, 2015 1,318 $ 16.68 6.2 $ 710 The aggregate intrinsic value in the table above represents the difference between the exercise price of the underlying awards and the estimated fair value of the Company’s common stock at December 31, 2015 multiplied by the number of shares that would have been received by the option holders had all option holders exercised their options on December 31, 2015. The aggregate intrinsic value of options exercised during the years ended December 31, 2015, 2014 and 2013 was $1,615, $1,465 and $3,295, respectively. The total unrecognized compensation cost related to outstanding stock options is $8,464 at December 31, 2015. This amount is expected to be recognized over a weighted-average period of 2.7 years.

The weighted average grant date fair value per share for stock options granted in 2015, 2014 and 2013 was $5.83, $11.57 and $10.34, respectively. The aggregate fair value of stock options that vested during the years ended December 31, 2015, 2014 and 2013 was $4,191, $5,422 and $3,481, respectively. As discussed in Note 3, the Company recognized stock-based compensation expense of $1,252 in the accompanying consolidated statement of operations and comprehensive loss for the year ended December 31, 2013, related to the earn-out arrangement associated with the Spend Radar acquisition. In addition, the Company recognized stock-based compensation expense of $976 in the accompanying consolidated statements of operations and comprehensive loss for the year ended December 31, 2013, related to the earn-out arrangement with certain former shareholders of AECsoft. Employee Stock Purchase Plan The Company adopted an Employee Stock Purchase Plan (the “Purchase Plan”) effective June 1, 2012. Eligible employees can contribute up to 10% of their gross earnings for each pay period, up to a maximum of $25 for any calendar year. The initial offering period that commenced on June 1, 2012 was a period of 12 months, and thereafter six month offering periods begin on December 1 and June 1 of each year. During the offering period eligible employees may elect to purchase shares of the Company’s common stock according to the terms of the offering. The per share purchase price is equal to the lessor of 85% of the fair market value of the Company’s common stock on the offering date or 85% of the fair market value of the Company’s common stock on the purchase date. As of December 31, 2015, 817 shares of common stock were available for issuance to participating employees under the Purchase Plan. During the years ended December 31, 2015, 2014 and 2013, the Company recognized stock-based compensation expense of $287, $293 and $273, respectively, related to the Purchase Plan.

During 2013, the Company acquired the stock of CombineNet in a tax-free reorganization under IRC Sec. 368(a)(2)(d). The acquisition resulted in a net deferred tax liability of $2,027 being recorded as part of purchase accounting, with a corresponding adjustment to goodwill. There was no impact to income tax expense. The tax effects of temporary differences that give rise to significant portions of the net deferred tax asset at December 31, 2015 and 2014 are as follows: 2015 2014 Deferred tax asset: Compensation accruals $ 1,801 $ 1,309 Other accruals 228 476 Net operating loss carryforwards 74,992 77,840 Foreign loss carryforward 9,055 3,645 Research and development tax credits 3,475 2,859 Deferred revenues 3,437 4,167 Stock compensation 5,610 4,157 Capitalized earn-out payments 2,494 2,723 Other credits 511 491 Other 395 606 Gross deferred tax asset 101,998 98,273 Less: valuation allowance for deferred tax asset (80,983 ) (76,175 ) Total deferred tax asset 21,015 22,098 Deferred tax liability: Depreciation and amortization 919 929 Trade names 156 158 Capitalized software costs 3,468 2,865 Identifiable intangibles 5,176 6,089 Total deferred tax liability 9,719 10,041 Net deferred tax asset $ 11,296 $ 12,057 As of December 31, 2015, the Company has federal and state net operating loss carryforwards of approximately $207,497 and $122,506, respectively, which will begin to expire in 2018 for federal tax purposes and began to expire in 2009 for state tax purposes. Furthermore, the Company has approximately $511 of alternative minimum tax credit carryforwards and $3,475 of net research and development credit carryforwards. The research and development credits remaining will begin to expire in 2018. The Tax Reform Act of 1986 contains provisions that limit the ability of companies to utilize net operating loss carryforwards and tax credit carryovers in the case of certain events including significant changes in ownership. These limitations may significantly impact the amount of net operating loss and tax credit carryovers available to offset future taxable income. As of December 31, 2015, the Company believes that federal and state net operating loss carryforwards in the amounts of $8,890 and $28,336, respectively, will be available for future utilization to the extent of future income. The Company has provided a valuation allowance for the remaining federal and state losses of $198,607 and $94,170, respectively, due to uncertainty regarding the Company’s ability to fully realize these assets. Additionally, the Company has a valuation allowance for its foreign net operating loss carryforwards. At December 31, 2015 and 2014, unrecognized tax benefits of $1,346 and $1,014, respectively, net of federal tax benefits, would have increased the Company’s deferred tax assets. This amount, if recognized, would impact the effective tax rate. The Company does not believe there will be any material changes in its unrecognized tax positions over the next twelve months. The following is a tabular reconciliation of the Company’s change in uncertain tax positions: 2015 2014 2013 Beginning Balance $ 1,014 $ 1,024 $ 515 Increases related to current year tax position 377 288 326 (Decreases) increases related to prior year tax positions (45 ) (298 ) 183 Ending balance $ 1,346 $ 1,014 $ 1,024 As of December 31, 2015 and 2014, the Company did not have any accrued interest or penalties associated with any unrecognized tax positions, and there were no such interest or penalties recognized during the years ended December 31, 2015, 2014 or 2013. The Company’s open tax years that are subject to federal examination are 2012 through 2014. All prior years with applicable net operating losses will remain open to the extent of the amount of the net operating loss. The Company provides for U.S. income taxes on earnings of foreign subsidiaries unless the subsidiaries’ earnings are considered indefinitely reinvested outside the United States. As of December 31, 2015, U.S. income taxes were not provided for any undistributed earnings for non-U.S. subsidiaries, as the Company currently intends to reinvest any earnings from foreign operations indefinitely.

Commitments and Contingencies	12. Commitments and Contingencies Operating Leases The Company leases office space under non-cancelable operating leases. The Company did not have any capital lease obligations as of December 31, 2015 or 2014. The Company is committed to a lease agreement for office space for its headquarters through July 2024. On July 29, 2014, the Company entered into a lease assignment, pursuant to which the Company assigned all of its right, title and interest in the Company’s office lease at its former headquarters. The assignment required the Company to pay an amount equal to $20 as an estimate of additional rental adjustments that are expected to be payable under the lease, and a lump sum payment to the landlord in the amount of $685 as a partial prepayment of rental payments owed under the lease for the remaining lease term. These costs, adjusted for the existing deferred rent balance of $468, are included in general and administrative expense in the accompanying consolidated statements of operations and comprehensive loss for the year ended December 31, 2014. In addition, in connection with the negotiation of the lease assignment, the Company incurred broker’s fees of $141, which are included in general and administrative expense for the year ended December 31, 2014. As discussed in Note 6, certain fixed assets were transferred in accordance with the lease assignment. The Company recognized a loss of $430 in the accompanying consolidated statements of operations and comprehensive loss for the year ended December 31, 2014 related to the disposal of these assets. The Company is also committed to leases through May 2016, June 2016, July 2018, March 2019, and June 2021. Future minimum lease payments required under leases in effect as of December 31, 2015 are as follows: Operating Leases 2016 $ 2,422 2017 2,239 2018 2,227 2019 2,099 2020 2,122 Thereafter 7,547 Total future minimum lease payments $ 18,656 Rent expense is calculated on a straight-line basis over the term of the lease. Rent expense recognized under operating leases totaled approximately $3,202, $3,190 and $2,378 for the years ended December 31, 2015, 2014 and 2013, respectively. Legal Contingencies From time to time, the Company is subject to legal proceedings and claims that arise in the ordinary course of business. The Company records an accrual for a contingency when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company is not currently subject to any material legal proceedings. Warranties and Indemnification The Company’s hosting service is typically warranted to perform in a manner consistent with general industry standards that are reasonably applicable under normal use and circumstances. The Company’s arrangements also include certain provisions for indemnifying customers against liabilities if its products or services infringe a third party’s intellectual property rights. The Company to date has not incurred costs to settle claims or pay awards under these indemnification obligations. The Company accounts for these indemnity obligations as contingencies and records a liability for these obligations when a loss is probable and reasonably estimable. To date, the Company has not incurred any material costs as a result of these indemnifications and has not accrued any liabilities related to the obligations in the accompanying consolidated financial statements. The Company enters into service level agreements with its cloud-based solution customers warranting certain levels of uptime reliability. To date, the Company has not incurred any material costs and has not accrued any liabilities related to such obligations.

Summary of Significant Accoun21

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”).
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates.
Revenue Recognition	Revenue Recognition The Company primarily derives its revenues from subscription fees and related services, permitting customers to access and utilize the Company’s cloud-based business automation solutions for spend management. Customers may also purchase a perpetual license for certain software products. Revenue is recognized when there is persuasive evidence of an arrangement, the service has been provided or delivered to the customer, the collection of the fee is probable and the amount of the fee to be paid by the customer is fixed or determinable. The Company’s arrangements do not contain general rights of return. Because customers do not have the right to take possession of the Software-as-a-Service (“SaaS”) based software, these arrangements are considered service contracts and are not within the scope of Industry Topic 985 , Software. Revenue Recognition for Multiple-Element Arrangements For arrangements in which elements do have stand-alone value, the Company allocates revenue to each element in the arrangement based on a selling price hierarchy. The selling price for a deliverable is based on vendor-specific objective evidence of selling price (“VSOE”), if available, third-party evidence of selling price (“TPE”), if VSOE is not available, or estimated selling price (“ESP”) if neither VSOE nor TPE is available. Because the Company has neither VSOE nor TPE for its deliverables, the allocation of revenue is based on ESP. The Company’s process for determining ESP for its deliverables considers multiple factors that may vary depending upon the facts and circumstances related to each deliverable. Key factors considered in developing ESP related to deliverables include established pricing and approval policies, type and size of customer, number of products purchased, and historical transactions. The Company regularly reviews ESP and maintains internal controls over the establishment and updates of these estimates. The Company evaluates its SaaS subscription agreements and considers whether the associated services have standalone value to its customers. For arrangements when implementation services do not have standalone value to the customer, licenses and related implementation services are considered a single unit of accounting. Accordingly, the consideration allocated to licenses and services is recognized ratably over the term of the subscription agreement, beginning with the later of the start date specified in the subscription agreement, or the date access to the software is provided to the customer, provided all other revenue recognition criteria have been met. Fees for professional services that are contingent upon future performance are recognized ratably over the remaining subscription term once the performance milestones have been met. Alternatively, when services have standalone value to the customer, licenses and related services are considered separate units of accounting. For separate units of accounting, services are recognized as the services are performed and delivered to the customer and licenses are recognized over the term of the subscription arrangement, beginning with the later of the start date specified in the subscription agreement, or the date access to the software is provided to the customer, provided all other revenue recognition criteria have been met. Revenue from sales of certain of the Company’s perpetual software products and related implementation services and maintenance is recognized as a single unit of accounting since VSOE of fair value does not exist for the contractual elements. Accordingly, revenue for all elements in these arrangements is recognized over the contractual maintenance term, which is typically one year. The Company recognizes revenue from any professional services that are sold separately as the services are performed. Sales taxes collected from customers and remitted to government authorities are excluded from revenue. Deferred revenue primarily consists of billings or payments received in advance of revenue recognition from the Company’s software and services described above. For multi-year subscription agreements, the Company generally invoices its customers in annual installments. Accordingly, the deferred revenue balance does not represent the total contract value of these multi-year subscription agreements. The Company’s services, such as implementation, are generally sold in conjunction with subscription agreements. These services are recognized ratably over the remaining term of the subscription agreement once any contingent performance milestones have been satisfied. The portion of deferred revenue that the Company anticipates will be recognized after the succeeding 12-month period is recorded as non-current deferred revenue and the remaining portion is recorded as current deferred revenue.
Cost of Revenues	Cost of Revenues Cost of revenues primarily consists of costs related to hosting the Company’s subscription software services, compensation and related expenses for implementation services, supplier enablement services, customer support staff and client partners, amortization of capitalized software development costs and allocated fixed asset depreciation and facilities costs. Cost of revenues is expensed as incurred.
Deferred Commissions	Deferred Commissions The Company capitalizes sales commission costs that are directly related to the execution of its subscription agreements. The commissions are deferred and amortized over the contractual term of the related non-cancelable subscription agreement. The Company believes this is the appropriate method of accounting, as the commission costs are so closely related to the revenues from the subscription agreements that they should be recorded as an asset and charged to expense over the same period that the subscription revenues are recognized. Amortization of deferred commissions is included in sales and marketing expense in the accompanying consolidated statements of operations and comprehensive loss.
Concentrations	Concentrations As of December 31, 2015 and 2014, no individual customer comprised more than 10% of the accounts receivable balance. During each of the years ended December 31, 2015, 2014 and 2013, no individual customer comprised more than 10% of the Company’s revenues. During the year’s ended December 31, 2015, 2014 and 2013, approximately 88%, 87% and 89%, respectively, of the Company’s revenue was from sales transactions originating in the United States. As of December 31, 2015 and 2014, all of the Company’s long-lived assets were located in North America.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid debt investments with an original maturity of three months or less at the date of purchase to be cash equivalents. The Company maintains cash balances at financial institutions that may at times exceed federally insured limits. The Company maintains this cash at reputable financial institutions and, as a result, believes credit risk related to its cash is minimal.
Short-Term Investments	Short-Term Investments Management determines the appropriate classification of investments at the time of purchase and evaluates such determination as of each balance sheet date. The Company’s investments were classified as available-for-sale securities and are stated at fair value at December 31, 2015 and 2014. Realized gains and losses are included in other income based on the specific identification method. There were no realized gains or losses for the years ended December 31, 2015, 2014 or 2013. Net unrealized gains and losses on available-for-sale securities are reported as a component of other comprehensive loss, net of tax. As of December 31, 2015 and 2014, there were no unrealized gains or losses on available-for-sale securities. The Company regularly monitors and evaluates the fair value of its investments to identify other-than-temporary declines in value. Management believes no such declines in value existed at December 31, 2015 or 2014.
Accounts Receivable	Accounts Receivable The Company assesses the need for an allowance for doubtful accounts based on estimates of probable credit losses. This assessment is based on several factors including aging of customer accounts, known customer specific risks, historical experience and existing economic conditions. The Company generally does not require collateral for receivable balances. Accounts would be charged against the allowance after all means of collection were exhausted and recovery was considered remote. Based on management’s analysis of its outstanding accounts receivable, the Company recorded an allowance of $473 and $1,100 at December 31, 2015 and 2014, respectively.
Property and Equipment	Property and Equipment Property and equipment are recorded at cost and depreciated using the straight-line method over their estimated useful lives, which are usually seven years for furniture and three to five years for computer software and equipment. Leasehold improvements are amortized over the shorter of the estimated useful lives of the assets or the remainder of the lease term. Costs for repairs and maintenance are expensed as incurred. Upon retirement or sale, the cost of the disposed assets and the related accumulated depreciation are removed from the accounts, and any resulting gain or loss is credited or charged to operations.
Software Development Costs	Software Development Costs The Company incurs certain costs associated with the development of its cloud-based solution, which are accounted for as internal-use software. Certain qualifying costs incurred during the application development phase are capitalized and amortized to expense over the estimated useful life of the related applications, which is generally three years.
Goodwill	Goodwill Goodwill represents the excess of the cost of an acquired entity over the net fair value of the identifiable assets acquired and liabilities assumed. Goodwill is not amortized, but rather is assessed for impairment at least annually. Additionally, the Company would also review the carrying value of goodwill whenever events or changes in circumstances indicated that its carrying amount may not be recoverable. The Company has concluded that it has one reporting unit for purposes of its annual goodwill impairment testing. To assess goodwill impairment, the first step is to identify if a potential impairment exists by comparing the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not considered to have a potential impairment and the second step of the impairment test is not necessary. The Company performed its annual assessments on December 31, 2015 and 2014. The estimated fair value of the Company’s reporting unit exceeded its carrying amount, including goodwill, and as such, no goodwill impairment was recorded.
Long-Lived Assets	Long-Lived Assets The Company evaluates the recoverability of its property and equipment and other long-lived assets, including acquired technology and customer relationships, when events change or circumstances indicate the carrying amount may not be recoverable. If such events or changes in circumstances are present, the undiscounted cash flow method is used to determine whether the asset is impaired. An impairment loss is recognized when, and to the extent, the net book value of such assets exceeds the fair value of the assets or the business to which the assets relate. Cash flows would include the estimated terminal value of the asset and exclude any interest charges. The discount rate utilized would be based on the Company’s best estimate of the related risks and return at the time the impairment assessment is made. There were no impairments losses recognized related to the Company’s long-lived assets during the years ended December 31, 2015, 2014, and 2013.
Sales and Marketing Expenses	Sales and Marketing Expenses Sales and marketing expenses consist primarily of costs, including salaries and sales commissions, of all personnel involved in the sales process. Sales and marketing expenses also include costs of advertising, trade shows, certain indirect costs and allocated fixed asset depreciation and facilities costs. Advertising costs are expensed as incurred. Advertising expenses totaled approximately $646, $883 and $678 for the years ended December 31, 2015, 2014 and 2013, respectively.
Stock-Based Compensation	Stock-Based Compensation Stock-based payments to employees, including grants of employee stock options, are recognized in the consolidated statement of operations and comprehensive loss based on their fair values. Stock-based compensation costs are measured at the grant date based on the fair value of the award and are recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes option-pricing model on the date of grant for stock options and a lattice model on the date of grant for performance-based restricted stock units. Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, forfeiture rates and expected term. The Company uses the historical volatility of its stock price to calculate the expected volatility. Prior to the second half of 2013, the expected volatility rates were estimated based on the actual volatility of comparable public companies over the expected term. The expected term for the years ended December 31, 2015, 2014 and 2013, represents the average time that options that vest are expected to be outstanding based on the mid-point between the vesting date and the end of the contractual term of the award. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.
Foreign Currency and Operations	Foreign Currency and Operations The reporting currency for all periods presented is the U.S. dollar. The functional currency for the Company’s foreign subsidiaries is generally their local currency. The translation of each subsidiary’s financial statements into U.S. dollars is performed for assets and liabilities using exchange rates in effect at the balance sheet date and for revenue and expense accounts using an average exchange rate during the period. The resulting translation adjustments are recognized in accumulated other comprehensive loss, a separate component of stockholders’ equity. At December 31, 2015 and 2014, accumulated other comprehensive loss was $(6,055) and $(3,055), respectively, which is predominantly due to the intercompany balance with the Company’s Canadian subsidiary not expected to be settled in the foreseeable future and the goodwill balance on the Company’s Canadian subsidiary. Realized foreign currency transaction gains and losses are included in the other income section of the consolidated statements of operations and comprehensive loss.
Income (Loss) Per Share	Income ( Loss) Per Share Basic net income (loss) per share is computed by dividing net income (loss) by the weighted-average number of shares of common stock outstanding for the period. Outstanding unvested restricted stock purchased by employees is subject to repurchase by the Company and therefore is not included in the calculation of the weighted-average shares outstanding until vested. Diluted net income (loss) per share is computed giving effect to all potentially dilutive common stock, including options and restricted stock. The dilutive effect of outstanding awards is reflected in diluted earnings per share by application of the treasury stock method. The following summarizes the calculation of basic and diluted net income (loss) per share: Year Ended December 31, 2015 2014 2013 Basic: Net income (loss) $ 1,862 $ (69 ) $ (4,734 ) Weighted average common shares, basic 27,721 26,609 23,044 Basic net income (loss) per share $ 0.07 $ (0.00 ) $ (0.20 ) Diluted: Net income (loss) $ 1,862 $ (69 ) $ (4,734 ) Weighted average common shares, basic 27,721 26,609 23,044 Dilutive effect of: Options to purchase common stock 122 - - Nonvested shares of restricted stock 34 - - Shares of employee stock purchase plan 12 - - Weighted average common shares, diluted 27,889 26,609 23,044 Diluted net income (loss) per share $ 0.07 $ (0.00 ) $ (0.20 ) The following equity instruments have been excluded from diluted net income (loss) per common share as they would be anti-dilutive. Year Ended December 31, 2015 2014 2013 Common stock options 602 373 77 For the years ended December 2014 and 2013, the Company incurred net losses and, therefore, the effect of the Company’s outstanding stock options, nonvested restricted stock and common stock issuable pursuant to the employee stock purchase plan was not included in the calculation of diluted net loss per share as the effect would be anti-dilutive. For the years ended December 31, 2014 and 2013, diluted net loss per share excluded the impact of 361 and 430 outstanding stock options, 13 and 28 nonvested shares of restricted stock, and approximately 18 shares of common stock issuable
Segment Data	Segment Data The Company manages its operations on a consolidated basis for purposes of assessing performance and making operating decisions. Accordingly, the Company has determined that it has a single reporting segment.
Income Taxes	Income Taxes Deferred income taxes are provided using tax rates enacted for periods of expected reversal on all temporary differences. Temporary differences relate to differences between the book and tax basis of assets and liabilities, principally intangible assets, property and equipment, deferred subscription revenues, accruals and stock-based compensation. Valuation allowances are established to reduce deferred tax assets to the amount that will more likely than not be realized. To the extent that a determination is made to establish or adjust a valuation allowance, the expense or benefit is recorded in the period in which the determination is made. Judgment is required in determining the provision for income taxes. Additionally, the income tax provision is based on calculations and assumptions that are subject to examination by many different tax authorities and to changes in tax law and rates in many jurisdictions. The Company would adjust its income tax provision in the period in which it becomes probable that actual results differ from management estimates. The Company accounts for uncertain tax positions by recognizing and measuring tax benefits taken or expected to be taken on a tax return. A tax benefit from an uncertain position may be recognized only if it is more likely than not that the position is sustainable, based solely on its technical merits and consideration of the relevant taxing authority’s widely understood administrative practices and precedents. If the recognition threshold is met, only the portion of the tax benefit that is greater than fifty percent likely to be realized upon settlement with a taxing authority is recorded. The tax benefit that is not recorded is considered an unrecognized tax benefit. Interest and penalties related to uncertain tax positions are recognized as a component of income tax expense.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2015, the FASB issued new guidance related to balance sheet classification of deferred taxes. The new guidance requires that deferred tax assets and liabilities be classified as noncurrent in a classified statement of financial position. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Early adoption is permitted. We early adopted this guidance during the year ended December 31, 2015. The retrospective application of this guidance decreased Current assets by $400 and increased Other assets by $400 to include the current portion of the deferred tax assets within the non-current portion of the deferred tax assets in the consolidated Balance Sheet as of December 31, 2014. In August 2014, the FASB issued new accounting guidance which addresses management’s responsibility to evaluate whether there is substantial doubt about the entity’s ability to continue as a going concern and to provide related footnote disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably knowable at the date that the financial statements are issued. This guidance is effective for the fiscal year ending after December 15, 2016, and for fiscal years and interim periods thereafter. Early adoption is permitted. The Company does not expect to early adopt this guidance and does not believe that the adoption of this guidance will have a material impact on its financial statements. In May 2014, the FASB issued new accounting guidance on revenue recognition, which provides for a single five-step model to be applied to all revenue contracts with customers. The new standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. Companies have an option to use either a retrospective approach or cumulative effect adjustment approach to implement the standard. The new standard was originally effective for fiscal years and interim periods within those years beginning after December 15, 2016 and early adoption was not permitted. In August 2015, the FASB approved a one year delay of the effective date to reporting periods beginning after December 15, 2017, while permitting companies to voluntarily adopt the new standard as of the original effective date. The Company will adopt this standard in the first quarter of 2018. The Company is currently evaluating the impact that the implementation of this standard will have on its financial statements.
