Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business	1. Description of Business Exa Corporation (the “Company” or “Exa”), a Delaware corporation, develops, sells and supports simulation software and services that vehicle manufacturers use to enhance the performance of their products, reduce product development costs and improve the efficiency of their design and engineering processes. The Company’s solutions enable engineers and designers to augment or replace conventional methods of evaluating designs that rely on expensive and inefficient physical prototypes and test facilities with accurate digital simulations that are more useful, cost effective and timely. The Company’s simulation solutions enable customers to gain crucial insights about design performance early in the design cycle, reducing the likelihood of expensive redesigns and late-stage engineering changes, which result in cost savings and fundamental improvements in the development process. The Company is primarily focused on the ground transportation market, but is also exploring the application of its capabilities in the aerospace, oil and gas production, chemical processing, architecture, engineering and construction, power generation, biomedical and electronics industries. Exa has offices and sells directly in the United States and through subsidiaries in France, Germany, Italy, Japan, Korea, China, and the United Kingdom. The Company also conducts business in Sweden, India, Brazil, Russia, Canada, Finland, Spain and Australia. The Company is subject to a number of risks common to companies in similar stages of development, including dependence on a small number of significant customers for a substantial portion of its revenues, the ability to attract and retain key personnel, competition from substitute products and services from larger companies, the need to continually develop commercially viable products, and risks associated with changes in information technology.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Applicable Accounting Guidance These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative nongovernmental GAAP as found in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”). Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. Reclassification Certain prior year amounts have been reclassified to be consistent with current year classifications. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. On an on-going basis, the Company evaluates its estimates and judgments, including those related to revenue recognition and allowance for doubtful accounts, stock- based compensation expense, intangible assets and other long-lived assets, certain accrued expenses and income taxes. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from management’s estimates if future events differ substantially from past experience, or other assumptions, while reasonable when made, do not turn out to be substantially accurate. Revenue Recognition The Company generates revenues from the licensing of its software products, typically in the form of one-year term “subscription” or capacity-based licenses that have a defined term, and from project fees for consulting services and training. Licenses for the Company’s software products may be software to be run on the customer’s own computer hardware, or provided in the form of software-as-a-service, via the Company’s hosted PowerFLOW ExaCLOUD and OnDemand offerings. Software The Company recognizes revenues from licensing the software products in accordance with ASC 985-605, Software Revenue Recognition The Company typically sells term and capacity-based software licenses combined in a bundled sale. For instance, when customers purchase simulation capacity, they typically also purchase a number of term-based licenses for preparation and analysis software. All of the Company’s software licenses include multiple elements such as maintenance and support. Pursuant to the guidance within ASC 985-605, the Company determined that since it does not have vendor-specific objective evidence of the fair value of the individual elements contained in a bundled sale of term and capacity-based software licenses, the arrangement is treated as a single unit of accounting and revenue is recognized ratably on a daily basis over the term of the license agreement, which coincides with the duration of the maintenance and support services. The Company’s arrangements typically do not include rights to carryover any unused capacity beyond the contractual license term or any customer right of return. Licenses have finite terms that are not extendible at their expiration, and capacity usage is limited by contract to the amount specified. The Company’s practice is not to modify existing capacity-based licenses to allow simulation capacity to be added to an existing arrangement. A customer desiring to purchase additional simulation capacity or to license additional users of the Company’s preparation and analysis software during the term of the original simulation license does so by entering into a separate arrangement. Revenue from these new arrangements is recognized over the term of the new agreements, which include bundled maintenance and support, and are for a term of less than twelve months, coterminous with the remaining term of the original simulation license. The Company commences recognition of term license revenue when persuasive evidence of an arrangement exists; delivery of the software or license keys has occurred and all service elements, if bundled or linked, have commenced; payment is fixed or determinable; and collection of the resulting receivable is considered probable by management. Payments received from customers in advance of revenue recognition are treated as deferred revenue. If training or consulting service projects are bundled with a software license sale or, as a result of specific facts and circumstances, are determined to be linked with a software license sale, the Company treats this as one arrangement and recognizes revenue ratably on a daily basis over the license period provided that delivery of all elements of the arrangement have commenced. Software as a service (OnDemand and ExaCLOUD) The Company recognizes revenue from software as a service arrangements in accordance with ASC 605. OnDemand capacity-based licenses allow the customer to buy simulation capacity as a service hosted by the Company and are sold based upon simulation capacity expected to be used within a certain time period—typically not exceeding one year. The contracts have finite terms that are not extendible at their expiration, and capacity usage is limited by contract to the amount specified. The Company’s practice is not to modify existing capacity-based licenses to allow simulation capacity to be added to an existing arrangement. A customer desiring to purchase additional simulation capacity or to license additional users of the Company’s preparation and analysis software during the term of the original simulation license must do so by entering into a separate arrangement. Revenue from these arrangements is recognized as the capacity is used. In the event that any capacity remains unused at the end of the term of the arrangement, it is recognized as revenue at that time. With the ExaCLOUD solution, customers have access to hosted simulation capacity as well as hosted preparation and analysis software through a web browser. The ExaCLOUD solution includes a “pay-as-you-use” model and an option to purchase a block of simulation capacity upfront to be used over a defined period—typically not exceeding one year. Revenue from these arrangements is recognized as the cloud hosting service is provided. Projects The Company also derives revenue from fees for separate, project-based services. The Company’s projects are typically short-term in nature and usually complete in less than 90 days. Project pricing is generally either fixed fee or time and material based. The Company recognizes revenue from these service arrangements in accordance with ASC 605. Projects are either sold as one deliverable, or as multiple deliverables with stand-alone For projects which have multiple deliverables, each with standalone value, the Company recognizes revenue based on ASC 605 and allocates the arrangement consideration based on the relative selling price of the deliverables. For project deliverables, the Company uses its best estimate of selling price (“BESP”) if vendor-specific Multiple element arrangements Multiple element arrangements may include customer rights to any combination of software, project deliverables, software as a service, maintenance and training. When more than one element is contained in a single arrangement, the Company first allocates total arrangement revenue based upon relative selling prices into two categories: (1) non-software components, such as services under projects not related to software licenses or software-as-a-service and (2) software components, such as software licenses, maintenance and support, and other software-related services. Revenue allocated to non-software services is recognized based on ASC 605 and the arrangement consideration is allocated based on the relative selling price of the deliverables. For non-software deliverables, the Company uses its best estimate of selling price (“BESP”) if vendor-specific objective evidence (“VSOE”) or third-party evidence of selling price (“TPE”) do not exist. Revenue allocated to products sold which meet the definition of software components is recognized based on software accounting guidance provided for in ASC 985-605. Under this guidance, most companies use the residual method to recognize revenue when a multiple element arrangement includes one or more software related elements to be delivered at a future date and VSOE of fair value of all undelivered elements exists (typically maintenance and other services), but does not exist for the delivered elements (typically the software). However, since the Company cannot establish VSOE for its undelivered elements, the entire software arrangement is deferred and recognized ratably over the contract (maintenance) period. This particularly includes the Company’s term-based licenses since the software license term and the maintenance term are co-terminus. Foreign Currency Translation The Company has foreign subsidiaries in the United Kingdom, France, Germany, Italy, Japan, Korea and China. Foreign subsidiary records are maintained in the local currency. Foreign currency effects are accounted for in accordance with ASC 830— Foreign Currency Matters Other than for its subsidiary in the United Kingdom, the functional currency for all of the Company’s subsidiaries is the respective local currency. The resulting gains and losses from translation are included as a component of other comprehensive income. Transaction gains and losses and re-measurement of assets and liabilities denominated in currencies other than an entity’s functional currency are included in other (expense) income, net. For the Company’s subsidiary in the United Kingdom, which is unable to generate sufficient cash flows in its local currency to sustain operational viability, all assets and liabilities are re-measured into United States dollars, with any resulting unrealized gains or losses being recorded as a component of other (expense) income, net. Foreign currency (loss) gain included in other (expense) income, net for the years ended January 31, 2016, 2015 and 2014 was $(322), $344 and $(83), respectively. Concentration of Credit Risk and Significant Customers Financial instruments that potentially subject the Company to concentration of credit risks are principally cash and cash equivalents and accounts receivable. The Company invests its cash and cash equivalents with high credit quality financial institutions, and consequently, the Company believes that such funds are subject to minimal credit risk. The Company maintains its cash in bank deposit accounts, which at times may exceed federally insured limits, but management believes that the deposits are not exposed to significant credit risk due to the financial position of the depository institutions in which those financial instruments are held. Concentrated credit risk with respect to accounts receivable is limited to large creditworthy customers. The Company periodically assesses the financial strength of its customers and believes that its accounts receivable credit risk exposure is minimal. The Company typically does not require collateral from its customers for sales on account. The Company has not experienced significant losses related to receivables from individual customers or groups of customers in any specific industry or geographic region. The following table provides information concerning customers that individually in the respective fiscal year accounted for greater than 10% of total revenues or 10% of accounts receivable, and their respective percentages of total revenues and accounts receivable, as of and for the years ended January 31, 2016, 2015 and 2014: Year Ended January 31, 2016 2015 2014 Percentage of Percentage of accounts receivable at fiscal year end Percentage of total revenues Percentage of accounts receivable at fiscal year end Percentage of total revenues Percentage of accounts receivable at fiscal year end Customer A * 14 % 10 % 16 % 12 % 21 % Customer B * 14 % * 17 % * * Customer C * 29 % * 16 % * 15 % Customer D * 10 % * 12 % * 14 % Customer E 12 % * * * * * * less than 10% Concentration of Other Risks The Company has one main data center provider, and several support providers (which handle overflow), to host or provide access to hardware for the Company’s OnDemand and ExaCLOUD application services to customers. The disruption of these services could have a material adverse effect on the Company’s business, financial position, and results of operations. Cash and Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with an original maturity of 90 days or less, that are not restricted as to withdrawal, to be the equivalent of cash for the purpose of consolidated balance sheet and statement of cash flows presentation. Cash equivalents consisted of money market accounts as of January 31, 2016 and 2015. The Company maintained $352 and $525 of restricted cash related to an operating lease at January 31, 2016 and 2015, respectively. Accounts Receivable and Allowances for Doubtful Accounts Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for doubtful accounts is provided to the extent that specific accounts receivable are considered to be uncollectible, based on historical experience, known collection issues, and management’s evaluation of outstanding accounts receivable at the end of the year. Uncollectible amounts, if any, are written-off against the allowance after all collection efforts have been exhausted. The Company recorded no bad debt expense during fiscal years ended January 31, 2016 and 2015. During the fiscal year ended January 31, 2014, the Company recorded $21 of net bad debt expense relating to write-offs of uncollectible receivables. Based on management’s analysis of its outstanding accounts receivable, and customers’ creditworthiness and collection history, the Company concluded that an allowance was not necessary as of January 31, 2016 and 2015. Property and Equipment, net Property and equipment, net is stated at cost. Major renewals, additions and betterments are capitalized to property accounts while replacements, maintenance and repairs which do not improve or extend the lives of the respective assets are expensed in the period incurred. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in the consolidated statement of operations. Depreciation is computed using the straight-line method over the estimated useful life of each asset, generally as follows: Asset classification Estimated Useful Life Computer equipment 3-5 years Software 3 years Office equipment and furniture 3-7 years Leasehold improvements Shorter of useful life or remaining life of lease Leasehold improvements and assets acquired under capital leases are typically amortized using the straight-line method over the shorter of the estimated useful life of the asset or the term of the lease. However, assets acquired under capital leases that contain bargain purchase options that are typically exercised are amortized over the estimated useful life of the asset. Amortization of leasehold improvements and assets acquired under capital leases is included in depreciation expense. Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparison of their carrying amounts to the future undiscounted cash flows the assets are expected to generate. If any long-lived assets are considered to be impaired, the impairment recognized equals the amount by which the carrying value of the assets exceeds its estimated fair value. The Company did not identify any indicators of impairment of its long-lived assets during the fiscal years ended January 31, 2016 and 2015. Research and Development Expenses Research and development expense includes costs incurred to develop intellectual property and are charged to expense as incurred. The costs for the development of new software and substantial enhancements to existing software are expensed as incurred until technological feasibility has been established, at which time any additional costs are capitalized. The Company has determined that technological feasibility is established at the time a working model of software is completed. Because the Company believes that, under its current process for developing software, completion of the software is essentially concurrent with the establishment of technological feasibility, no costs have been capitalized to date. Internal-Use Software Costs incurred in the research and development of the Company’s software products are expensed as incurred. Costs incurred during the application development stage of internal-use software projects, such as those used to develop internal systems, are capitalized. Capitalized costs include external consulting fees and payroll and payroll-related costs for employees in the Company’s development and information technology groups who are directly associated with, and who devote time to, the Company’s internal-use software projects during the application development stage. Capitalization begins when the planning stage is complete and the Company commits resources to the software project. Amortization of the asset commences when the software is complete and placed in service. The Company amortizes completed internal-use software over its estimated useful life. Costs incurred during the planning, training and post-implementation stages of the software development life-cycle are expensed as incurred. Costs related to upgrades and enhancements of existing internal-use software that increase the functionality of the software are also capitalized. Advertising Costs Advertising costs are expensed as incurred. To date, the Company has not incurred significant advertising costs. Income Taxes Income taxes are accounted for in accordance with ASC 740, Income Taxes In determining the realizability of the net United States federal and state deferred tax assets, the Company considers numerous factors including historical profitability, estimated future taxable income, prudent and feasible tax planning strategies and the industry in which it operates. Management reassesses the realization of the deferred tax assets each reporting period, which resulted in a valuation allowance against the full amount of the Company’s United States net deferred tax assets being recorded in fiscal year 2015 and continuing to be recorded as of January 31, 2016 and 2015. To the extent that the financial results of the United States operations improve in the future and the deferred tax assets become more likely than not realizable, the Company will reduce the valuation allowance through earnings. The Company follows ASC 740-10-25 with regards to accounting for uncertain tax positions, which prescribes a threshold for the financial statement recognition and measurement of a tax position taken or expected to be taken within an income tax return. For each tax position, the enterprise must determine whether it is more likely than not that the position will be sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation. A tax position that meets the more likely than not recognition threshold is then measured to determine the amount of benefit to recognize within the financial statements. No benefits may be recognized for tax positions that do not meet the more likely than not threshold. The Company’s intention is to indefinitely reinvest the total amount of its unremitted foreign earnings in the local international jurisdictions, except for instances where the Company can remit such earnings to the United States without an associated net tax cost. As a result, the Company currently does not provide for United States taxes on the unremitted earnings of its international subsidiaries. Comprehensive Loss and Accumulated Other Comprehensive Loss ASC 220, Comprehensive Income Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718, Compensation—Stock Compensation ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures rates differ from those estimates. Forfeitures are estimated based on historical experience. The Company recognizes windfall tax benefits associated with the exercise of stock options or release of restricted stock units directly to stockholders’ equity only when realized. A windfall tax benefit occurs when the actual tax benefit realized by the Company upon an employee’s disposition of a share-based award exceeds the deferred tax asset, if any, associated with the award that we had recorded. When assessing whether a tax benefit relating to share-based compensation has been realized, the Company follows the “with-and-without” method. Under the with-and-without method, the windfall is considered realized and recognized for financial statement purposes only when an incremental benefit is provided after considering all other tax benefits including the Company’s net operating losses. The with-and-without method results in the windfall from share-based compensation awards always being effectively the last tax benefit to be considered. Consequently, the windfall attributable to share-based compensation will not be considered realized in instances where our net operating loss carryover (that is unrelated to windfalls) is sufficient to offset the current year’s taxable income before considering the effects of current-year windfalls. Net Loss per Share Net loss per share is computed using the weighted average number of shares of common stock outstanding during each period. Diluted amounts per share include the impact of the Company’s outstanding potential common shares, such as shares issuable upon exercise of in-the-money stock options or warrants or upon conversion of convertible preferred stock, when dilutive. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net loss income per common share.

Included in computer software and equipment and office equipment and furniture is equipment held pursuant to capital leases with costs of $14,809 and $18,303 and accumulated depreciation of $6,808 and $12,736 as of January 31, 2016 and 2015, respectively. In January 2016, the Company substantially completed the renovation of its headquarters in Burlington, Massachusetts. In conjunction with these renovations, the Company capitalized $1,448 of furniture and equipment purchases, along with $1,201 of leasehold improvement construction. Additionally, the Company disposed of $2,290 of previously capitalized leasehold improvement construction and $8,129 of various computer equipment and furniture. All assets were fully depreciated and no gain or loss was recognized in conjunction with the disposals. The Company periodically reviews the estimated useful lives of property and equipment. Changes to the estimated useful lives are recorded prospectively from the date of the change. During the first quarter of fiscal year 2014, the Company reevaluated its network assets, consisting primarily of server equipment utilized in its data centers, and determined that the expected average useful life of those assets had increased from three to five years, due to advances in technology and increased durability of the server equipment. The net book value of server assets placed in service as of February 1, 2013 was approximately $2,755. This change resulted in a decrease in depreciation expense on these assets of approximately $456 on an after-tax basis, for the fiscal year ended January 31, 2014.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements Financial instruments consist primarily of cash and cash equivalents, accounts receivable and capital lease obligations. As of January 31, 2016 and 2015, the carrying amounts of these instruments approximate their fair values. The estimated fair values have been determined from information obtained from market sources and management estimates. In determining the fair value of its financial assets and liabilities, the Company uses various valuation approaches. ASC 820, Fair Value Measurements and Disclosures Level 1—Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access. Level 2—Valuations based on quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active and models for which all significant inputs are observable, either directly or indirectly. Level 3—Valuations based on inputs that are unobservable and significant to the overall fair value measurement and that are based on management’s best estimate of inputs market participants would use for pricing the asset or liability at the measurement date, including assumptions about risk. The availability of observable inputs can vary among the various types of financial assets and liabilities. To the extent that the valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for financial statement disclosure purposes, the level in the fair value hierarchy within which the fair value measurement is categorized is based on the lowest level input that is significant to the overall fair value measurement. The following table summarizes the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value as of January 31, 2016: Total Level 1 Level 2 Level 3 Assets: Money market funds $ 11,019 $ 11,019 $ — $ — The following table summarizes the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value as of January 31, 2015: Total Level 1 Level 2 Level 3 Assets: Money market funds $ 12,514 $ 12,514 $ — $ —

Debt Disclosure [Abstract]
Debt	8. Debt Loan and Security Agreement On January 28, 2011, the Company entered into a Loan and Security Agreement with Gold Hill Capital 2008, L.P. (“Gold Hill”) and Massachusetts Capital Resource Company (the “Loan and Security Agreement”), which provided for term loans of up to $8,500, of which $1,000 was with a related party. On May 31, 2013, as described more fully below, the Company repaid, with available cash on hand, all outstanding obligations under the Loan and Security Agreement. Under the Loan and Security Agreement, which was subsequently amended and extended at various times through January 30, 2012, the Company borrowed $5,000 on January 28, 2011 and an additional $3,500 on March 30, 2012, for a total borrowed amount of $8,500. The Loan and Security Agreement contained customary representations, warranties and reporting requirements, but no financial covenants. The term was for 54 months from the borrowing dates (the January 28, 2011 draw matured on August 1, 2015 and the March 30, 2012 draw matured on October 1, 2016) and the loans bore interest at 10.5% per annum. An additional 2.5% ($125 on the January 28, 2011 draw and $87 on the March 30, 2012 draw) was due at maturity and was originally recorded as a long-term liability and a debt discount. Interest only payments were payable during the first twelve months with principal and interest payments required for forty-two months thereafter. Included in interest expense in the accompanying consolidated statements of operations was interest paid to related parties under the Loan and Security Agreement of $0, $0 and $26 for the fiscal years ended January 31, 2016, 2015 and 2014, respectively. On May 31, 2013 the Company repaid, with available cash on hand, all outstanding obligations under the Loan and Security Agreement. The repayment amount included $6,852 of outstanding principal, $60 of accrued interest and $213 of deferred origination fees that were accrued for in other long-term liabilities in the accompanying consolidated balance sheet. In addition, in accordance with the terms of the agreement, the Company paid a prepayment interest penalty of $290, representing 3% of the amount advanced to the Company under the agreement in January 2011 and 4% of the amount advanced to the Company under the agreement in March 2012. The Company recognized a loss from the extinguishment of this debt of $755 during the second quarter of fiscal year 2014, representing the prepayment interest penalty and the write-off of unamortized debt discount. In connection with the Loan and Security Agreement, and its subsequent amendments and extensions, the Company issued warrants to purchase shares of the Company’s Series G Convertible Preferred Stock (see Note 9). The Company recorded the original fair value of the warrants as debt discount with an offset to preferred stock warrant liability. The debt discount was amortized over the term of the loans using the effective interest method, with the unamortized debt discount as of the date of early payoff being written off to loss from the extinguishment of debt. For the fiscal years ended January 31, 2016, 2015 and 2014, the Company recorded $0, $0 and $131, respectively, in non-cash interest expense relating to this debt discount.

Warrants for Preferred Stock	9. Warrants for Preferred Stock In connection with the Loan and Security Agreement, and its subsequent amendments and extensions (see Note 8), the Company issued various warrants to purchase an aggregate 1,190,000 shares of the Company’s Series G Convertible Preferred Stock at an exercise price of $0.94 per share. The warrants were issued at various times during the fiscal years ended January 31, 2011 and 2012 and had terms ranging from nine to ten years. The Company calculated the fair value of the warrants utilizing the Black-Scholes option pricing model with the following ranges of assumptions: volatility of 54.92% to 55.73%, term of nine to ten years, risk-free interest rate of 1.83% to 3.36%, and a dividend yield of 0%. The Company recorded the original fair value of the warrants, aggregating $1,049, as debt discount with an offset to preferred stock warrant liability. The preferred stock warrant liability was marked to market on a quarterly basis with the offsetting adjustment reflected in other income (expense), net in the accompanying consolidated statements of operations. As a result of the 1-for-6.5 reverse stock split effected with respect to the Company’s common stock on June 8, 2012, and the conversion to common stock of all outstanding shares of preferred stock upon the closing of the Company’s initial public offering on July 3, 2012, the warrants became exercisable for 183,076 shares of common stock at an exercise price of $6.11 per share. In addition, upon the closing of the initial public offering, the Company performed a final mark-to-market adjustment of the fair value of the warrants and recorded a gain of $165 to other income (expense), net in the second quarter of fiscal year 2013. Lastly, upon closing of the initial public offering, the warrants were no longer required to be classified as a liability and the final warrant fair value of $1,324 was reclassified to additional paid-in capital. On July 6, 2012, Gold Hill exercised warrants on a cashless basis to purchase an aggregate 161,538 shares of common stock, as a result of which the Company issued 67,268 shares of common stock. In July 2015, Massachusetts Capital Resource Company exercised warrants to purchase 21,538 shares of common stock at a cash exercise price of $6.11 per share. The Company has no remaining outstanding warrants as of January 31, 2016.

Commitments and Contingencies	10. Commitments and Contingencies Capital Leases The Company leases certain equipment under capital leases expiring on various dates through fiscal 2019. Future minimum lease payments under capital lease commitments as of January 31, 2016 are as follows: Year ended January 31, 2017 2,962 2018 1,720 2019 877 Total future minimum lease payments 5,559 Less: Interest 187 Present value of future minimum lease payments 5,372 Current portion of capital lease obligation 2,823 Long-term capital lease obligation $ 2,549 Operating Leases Effective July 1, 2015, the Company entered into an amendment to the lease for its corporate headquarters space in Burlington, Massachusetts. The amendment extends the lease term, originally set to expire in March 2016, through March 2023 and reduces the leased space from 65,941 square feet to 44,241 square feet. The 21,700 square foot reduction primarily relates to first floor space that had been subleased by the Company to a subtenant, and under the terms of the amendment, the landlord assumed the sublease effective July 1, 2015. The amendment also provides for a tenant improvement allowance of up to $1,681 to cover renovations that are being made to the retained second floor space over the remainder of fiscal year 2016. Management believes that the renovated space will be suitable and adequate to meet the Company’s planned growth needs at its headquarters over the next several years. In conjunction with the relinquishment of the first floor space, the amendment reduced the Company’s required security deposit letter of credit from $525 to $352. The reduction of the letter of credit is reflected as a change in restricted cash in the investing activity section of the accompanying consolidated statement of cash flows. In conjunction with the purchase of additional computer processor equipment for its high performance computing data center in New Jersey, effective as of September 1, 2015, the Company’s hosting and support arrangement for that facility was expanded to account for the new equipment. The Company leases office facilities for all its other locations under operating leases expiring on various dates through April 2024. The Company also leases certain office equipment under operating leases that expire on various dates through February 2018. As of January 31, 2016, after taking into consideration the above amendments, total future minimum lease payments under non-cancelable lease and hosting arrangements are as follows: Year ended January 31, 2017 $ 4,457 2018 4,493 2019 4,114 2020 3,249 2021 2,002 Thereafter 4,807 $ 23,122 Rent expense is calculated on a straight-line basis over the term of the lease. Rent expense recognized under all operating leases totaled $2,740, $2,699 and $2,823 for the fiscal years ended January 31, 2016, 2015 and 2014, respectively. Sub-rental income was $159, $382 and $324 for the fiscal years ended January 31, 2016, 2015 and 2014, respectively. Purchase Obligations The Company has minimum annual purchase commitments for certain sublicenses. As of January 31, 2016, the obligations payable relating to these commitments is $600 for each of the fiscal years 2017, 2018 and 2019. Legal Contingencies From time to time the Company is involved in legal proceedings arising in the ordinary course of business. There is no litigation pending that could, individually or in the aggregate, have a material adverse effect on the Company’s financial position, results of operations, or cash flows. Guarantees and Indemnification Obligations The Company enters into standard indemnification agreements in the ordinary course of business. Pursuant to these agreements, the Company indemnifies, holds harmless, and agrees to reimburse the indemnified party for losses suffered or incurred by the indemnified party, generally the Company’s business partners or customers, in connection with any United States patent, or any copyright or other intellectual property infringement claim by any third party with respect to the Company’s products. The term of these indemnification provisions is generally perpetual after execution of the agreement. The maximum potential amount of future payments the Company could be required to make under these agreements is unlimited. Based on historical experience and information known as of January 31, 2016 and 2015, the Company has not recorded any liabilities for the above guarantees and indemnities.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	11. Stock-Based Compensation Summary of Plans The Company’s equity compensation plans generally provide the board of directors the authority to grant incentive stock options, nonqualified stock options, restricted stock awards, unrestricted stock awards, performance share awards, restricted stock units, and stock appreciation rights (collectively, options) and to select the employees and consultants to whom options are granted and determine the terms of each option, including (i) the number of shares of common or preferred stock subject to the option, (ii) when the option becomes exercisable, (iii) the option exercise price, which, in the case of incentive stock options, must be at least 100% (110% in the case of incentive stock options granted to a stockholder owning in excess of 10% of the Company’s common stock) of the fair market value of the stock as of the date of grant and (iv) the duration of the option (which, in the case of incentive stock options, may not be less than five years or exceed 10 years). Options generally expire 10 years from the date of issuance. On June 10, 2014, the Company’s stockholders approved the amendment and restatement of the Company’s 2011 Stock Incentive Plan. As a result, the number of shares available to be issued under the plan increased from 769,230 to 1,769,230 shares of common stock. The Company’s common and preferred stock incentive plans are summarized as follows (the table reflects options for preferred stock on an as converted to common stock basis): Plan Authorized and Reserved Outstanding January 31, 2016 Available to Issue 1999 Series G Convertible Preferred Nonqualified Stock Option Plan (1) 384,615 — — 2005 Series G Convertible Preferred Stock Incentive Plan (1) 1,846,153 179,257 — 2007 Stock Incentive Plan (1) 1,076,923 656,338 — 2011 Stock Incentive Plan 1,769,230 1,301,375 (2) 420,202 5,076,921 2,136,970 420,202 (1) Effective upon the consummation of its initial public offering on July 3, 2012, the Company ceased issuing awards under any plan other than its 2011 Stock Incentive Plan. (2) Outstanding awards include 24,867 restricted stock units granted during the year to certain members of the board of directors, which will fully vest in June 2016. Grant-Date Fair Value All options have been granted at exercise prices not less than the fair value of the underlying shares on the date of grant. The Company uses the Black-Scholes option pricing model to calculate the grant-date fair value of stock options issued. The Black-Scholes model requires estimates regarding volatility, expected life of the award, the risk-free rate of return, dividend yields, and estimated forfeitures of awards during the service period. The Company computes volatility under the “calculated value method” of ASC 718, Compensation—Stock Compensation Since adopting ASC 718, the Company has been unable to use historical employee exercise and option expiration data to estimate the expected term assumption for the Black-Scholes grant-date valuation. As such, the Company has utilized the “simplified” method, as prescribed by Staff Accounting Bulletin No. 107, Share-Based Payment The Company utilizes the Federal Reserve Board’s published Treasury Constant Maturity rate which most closely matches the option term. As an example, for a 6.25 year term, the Company would use the 7-year rate coinciding with the option issuance date. The Company has never paid dividends and does not currently intend to pay dividends, and thus has assumed a dividend yield of zero. The Company estimates potential forfeitures of stock grants and adjusts compensation cost recorded accordingly. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ, or are expected to differ, from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will also impact the amount of stock compensation expense to be recognized in future periods. The Company considers the indirect effect of income tax benefits from stock-based compensation in arriving at its income tax provision. In addition, the Company has elected to recognize excess income tax benefits from stock-based compensation as an addition to paid-in capital only if an incremental income tax benefit would be realized by applying the with-and-without method. Under this method, the excess tax benefit is considered realized and recognized for financial statement purposes only when an incremental benefit is provided after considering all other tax benefits including the Company’s net operating losses. The Company measures the tax benefit associated with excess tax deductions by multiplying the excess tax over book deduction by the statutory tax rates. The fair value of common stock service-based options for employees and directors is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions used: Year Ended January 31, 2016 2015 2014 Expected life (years) 6.25 6.25 6.25 Risk-free interest rate 1.96 % 2.15 % 2.21 % Expected volatility 36.8 % 47.3 % 50.6 % Expected dividend yield 0.0 % 0.0 % 0.0 % A summary of the changes in common stock options issued under all of the existing stock option plans is as follows (the table reflects options for preferred stock on an as converted to common stock basis): Year Ended January 31, 2016 Number of Weighted Average Exercise Price Weighted Average Remaining Contractual Term (in years) Aggregate Intrinsic Value (1) Outstanding—beginning of period 2,809,960 $ 7.57 Granted 130,284 10.68 Exercised (747,818 ) 1.41 Cancelled (80,323 ) 11.71 Outstanding—end of period 2,112,103 $ 9.79 6.5 $ 3,689 Exercisable—end of period 1,245,480 $ 9.12 5.2 $ 2,976 Vested or Expected to Vest—end of period 1,877,880 $ 9.76 6.2 $ 3,468 (1) The aggregate intrinsic value was calculated based on the positive difference between the fair value of the Company’s stock on January 31, 2016 and the exercise price of the underlying options. The following table summarizes information relating to stock options granted and exercised: Year Ended January 31 2016 2015 2014 Weighted average fair value of options granted $ 10.68 $ 10.67 $ 6.80 Aggregate intrinsic value of options exercised (1) 6,812 5,503 528 (1) The aggregate intrinsic value was calculated based on the positive difference between the fair value of the Company’s stock at exercise and the exercise price of the underlying options. In June 2015, 19,521 restricted stock units, granted to certain members of the board of directors, vested with a fair market value of $180. The Company also granted 24,867 restricted stock units to certain members of the board of directors, which will fully vest in June 2016. Stock-Based Compensation Expense For standard service-based stock options, the Company records stock-based compensation expense over the estimated service/vesting period. The amount of stock-based compensation expense recognized during a period is based on the value of the portion of the awards that are ultimately expected to vest. Performance-based stock options are recognized as expense over the requisite service period when it becomes probable that performance measures triggering vesting will be met. During fiscal year 2015, the Company granted performance-based options with vesting criteria tied to performance metrics for fiscal years 2015 and 2016. Required metrics for certain grants eligible to vest were achieved in fiscal years 2015 and 2016, and, accordingly, the Company has recorded $289 and $410, respectively, in share-based compensation expense associated with these options. Total stock-based compensation expense was recorded within the consolidated statement of operations for the fiscal years ended January 31, 2016, 2015 and 2014 as follows: Year Ended January 31 2016 2015 2014 Cost of revenues $ 234 $ 209 $ 137 Sales and marketing 405 413 239 Research and development 886 865 376 General and administrative 751 743 458 Total $ 2,276 $ 2,230 $ 1,210 The total unrecognized compensation cost related to outstanding stock options is $3,804 at January 31, 2016. This amount is expected to be recognized over a weighted-average period of 1.93 years.

The income tax provision for fiscal year 2015 includes a $14,423 non-cash charge to record a valuation allowance against the Company’s United States net deferred tax assets and a $788 non-cash write-off of state deferred tax assets (discussed further below). During fiscal year 2015, the Company determined that the United States federal and state net deferred tax assets were no longer more-likely-than-not realizable. As a result, the Company recorded a deferred tax provision of $14,423 to establish a valuation allowance on the full amount of the United States federal and state net deferred tax assets. In determining the realizability of these assets, the Company considered numerous factors including historical profitability, estimated future taxable income, prudent and feasible tax planning strategies and the industry in which it operates. Through the three months ended April 30, 2014, the Company’s results reflected a three-year cumulative loss position in the United States; prior thereto, the historical results reflected a three-year cumulative profit. Reflecting management’s plans to continue investing in the business for future growth, the Company continued in a three-year cumulative loss position through the remainder of fiscal year 2015 and throughout 2016. The Company’s cumulative historical loss position at April 30, 2014 and projected cumulative loss position resulted in significant negative evidence which caused management to modify its assessment of the Company’s deferred tax assets, concluding that it no longer was more likely than not that these deferred tax assets would be realized and thus, a valuation allowance was necessary against the full amount of our United States net deferred tax assets; this conclusion has continued through January 31, 2016. Most of the Company’s revenues are generated from ground transportation customers outside the United States but a significantly disproportionate amount of the Company’s operating expenses, including investments in future products, are incurred in the United States, causing the results of operations in the United States to reflect losses during this period of investment. Management reassesses the realization of the deferred tax assets each reporting period. To the extent that the financial results of the Company’s United States operations improve and the deferred tax asset becomes realizable, the Company will reduce the valuation allowance through earnings. Under Section 382 of the Internal Revenue Code of 1986, as amended, substantial changes in the Company’s ownership may limit the amount of net operating loss carryforwards that can be utilized annually in the future to offset its United States federal taxable income. Specifically, this limitation may arise in the event of a cumulative change in ownership of the Company of more than 50% within a three-year period. During the first quarter of fiscal year 2015, management determined that the Company had experienced an ownership change for purposes of Section 382. This ownership change resulted in annual limitations to the amount of net operating loss carryforwards that can be utilized to offset future taxable income, if any, at the federal level. The annual limit was approximately $14,032 for fiscal year 2015, $16,758 for each of fiscal years 2016 through 2019, $8,046 for fiscal year 2020 and $6,366 for each fiscal year thereafter. The ownership change also resulted in the loss of the Company’s ability to utilize $788 of its $819 of state net operating loss carryforwards, credits and other state attributes, which resulted in a write-off of the $788 of state deferred tax assets. As of January 31, 2016, the Company had United States federal net operating loss carryforwards of $28,782, which will begin to expire in fiscal year 2018, and state net operating loss carryforwards of $1,035, which will begin to expire in fiscal year 2025. The Company has an additional $1,130 of federal and state net operating losses not reflected above (net of tax), that are attributable to stock option exercises, which will be recorded as an increase in additional paid-in capital on the Company’s consolidated balance sheet once they are “realized” in accordance with ASC 718, Compensation—Stock Compensation Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not that the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. The Company reevaluates these uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company has gross unrecognized tax benefits of $2,836 and $2,442 at January 31, 2016 and 2015, respectively, of which $2,163 and $1,972, if recognized respectively, would result in a reduction to the Company’s effective tax rate. A tabular roll forward of the Company’s uncertainties in its income tax provision liability is presented below: Year Ended January 31 2016 2015 Gross balance at February 1 $ 2,442 $ 2,167 Additions based on tax positions related to the current year 485 648 Reductions for tax positions of prior years (91 ) (373 ) Gross balance at January 31 $ 2,836 $ 2,442 The Company classifies interest and penalties related to unrecognized tax benefits as income tax expense. These amounts are not reflected in the reconciliation above. The total amount of interest and penalties related to uncertain tax positions and recognized in the balance sheet as of January 31, 2016 and 2015 was $97 and $78, respectively. It is reasonably possible within the next twelve months that the liability for unrecognized tax benefits relating to transfer pricing in a foreign jurisdiction will decrease by approximately $399, inclusive of interest, primarily as a result of the expiration of the statute of limitations. The Company and one or more of its subsidiaries file United States federal income tax returns and tax returns in various state and foreign jurisdictions. With limited exceptions, the Company is no longer subject to federal, state or local examinations for years prior to January 31, 2011. However, carryforward attributes that were generated prior to January 31, 2012 may still be adjusted upon examination by federal, state or local tax authorities if they either have been or will be used in a future period. The Company’s intention is to indefinitely reinvest the total amount of its unremitted earnings in the local international jurisdiction, except for instances in which the Company can remit such earnings to the United States without an associated net tax cost. Events that could trigger a tax might include United States acquisitions or other investments funded by cash distributions or loans from a foreign subsidiary. Because of the complexity of United States and foreign tax rules applicable to the distribution of earnings from foreign subsidiaries to United States legal entities, the determination of the unrecognized deferred tax liability on these earnings is not practicable. The Company has not provided for United States taxes on the unremitted earnings of its international subsidiaries of $5,010.

Earnings Per Share [Abstract]
Net Loss per Share	13. Net Loss per Share Net loss per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted amounts per share include the impact of the Company’s outstanding potential common shares, such as shares issuable upon exercise of in-the-money stock options or warrants, when dilutive. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net loss per common share. The following table sets forth the components of the computation of basic and diluted net loss per common share for the periods indicated: Year Ended January 31, 2016 2015 2014 Numerator: Net loss $ (4,807 ) $ (19,157 ) $ (709 ) Denominator: Weighted average common shares, basic and diluted 14,520,834 13,735,897 13,326,883 Basic and diluted net loss per share $ (0.33 ) $ (1.39 ) $ (0.05 ) All of the Company’s outstanding stock options and unvested restricted stock unit awards were excluded from the computation of diluted net loss per share for the years ended January 31, 2016, 2015 and 2014 because including them would have had an anti-dilutive effect due to the net loss position of the Company. At January 31, 2016, 2015 and 2014, the Company had outstanding options, unvested restricted stock unit awards and warrants of 2,136,970, 2,851,394 and 2,401,649, respectively.

Summary of Significant Accoun25

Summary of Significant Accounting Policies (Policies)	12 Months Ended

Accounting Policies [Abstract]
Applicable Accounting Guidance	Applicable Accounting Guidance These consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). Any reference in these notes to applicable accounting guidance is meant to refer to the authoritative nongovernmental GAAP as found in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”).
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.
Reclassification	Reclassification Certain prior year amounts have been reclassified to be consistent with current year classifications.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Although the Company regularly assesses these estimates, actual results could differ materially from these estimates. On an on-going basis, the Company evaluates its estimates and judgments, including those related to revenue recognition and allowance for doubtful accounts, stock- based compensation expense, intangible assets and other long-lived assets, certain accrued expenses and income taxes. Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other assumptions that it believes to be reasonable under the circumstances. Actual results could differ from management’s estimates if future events differ substantially from past experience, or other assumptions, while reasonable when made, do not turn out to be substantially accurate.
Revenue Recognition	Revenue Recognition The Company generates revenues from the licensing of its software products, typically in the form of one-year term “subscription” or capacity-based licenses that have a defined term, and from project fees for consulting services and training. Licenses for the Company’s software products may be software to be run on the customer’s own computer hardware, or provided in the form of software-as-a-service, via the Company’s hosted PowerFLOW ExaCLOUD and OnDemand offerings. Software The Company recognizes revenues from licensing the software products in accordance with ASC 985-605, Software Revenue Recognition The Company typically sells term and capacity-based software licenses combined in a bundled sale. For instance, when customers purchase simulation capacity, they typically also purchase a number of term-based licenses for preparation and analysis software. All of the Company’s software licenses include multiple elements such as maintenance and support. Pursuant to the guidance within ASC 985-605, the Company determined that since it does not have vendor-specific objective evidence of the fair value of the individual elements contained in a bundled sale of term and capacity-based software licenses, the arrangement is treated as a single unit of accounting and revenue is recognized ratably on a daily basis over the term of the license agreement, which coincides with the duration of the maintenance and support services. The Company’s arrangements typically do not include rights to carryover any unused capacity beyond the contractual license term or any customer right of return. Licenses have finite terms that are not extendible at their expiration, and capacity usage is limited by contract to the amount specified. The Company’s practice is not to modify existing capacity-based licenses to allow simulation capacity to be added to an existing arrangement. A customer desiring to purchase additional simulation capacity or to license additional users of the Company’s preparation and analysis software during the term of the original simulation license does so by entering into a separate arrangement. Revenue from these new arrangements is recognized over the term of the new agreements, which include bundled maintenance and support, and are for a term of less than twelve months, coterminous with the remaining term of the original simulation license. The Company commences recognition of term license revenue when persuasive evidence of an arrangement exists; delivery of the software or license keys has occurred and all service elements, if bundled or linked, have commenced; payment is fixed or determinable; and collection of the resulting receivable is considered probable by management. Payments received from customers in advance of revenue recognition are treated as deferred revenue. If training or consulting service projects are bundled with a software license sale or, as a result of specific facts and circumstances, are determined to be linked with a software license sale, the Company treats this as one arrangement and recognizes revenue ratably on a daily basis over the license period provided that delivery of all elements of the arrangement have commenced. Software as a service (OnDemand and ExaCLOUD) The Company recognizes revenue from software as a service arrangements in accordance with ASC 605. OnDemand capacity-based licenses allow the customer to buy simulation capacity as a service hosted by the Company and are sold based upon simulation capacity expected to be used within a certain time period—typically not exceeding one year. The contracts have finite terms that are not extendible at their expiration, and capacity usage is limited by contract to the amount specified. The Company’s practice is not to modify existing capacity-based licenses to allow simulation capacity to be added to an existing arrangement. A customer desiring to purchase additional simulation capacity or to license additional users of the Company’s preparation and analysis software during the term of the original simulation license must do so by entering into a separate arrangement. Revenue from these arrangements is recognized as the capacity is used. In the event that any capacity remains unused at the end of the term of the arrangement, it is recognized as revenue at that time. With the ExaCLOUD solution, customers have access to hosted simulation capacity as well as hosted preparation and analysis software through a web browser. The ExaCLOUD solution includes a “pay-as-you-use” model and an option to purchase a block of simulation capacity upfront to be used over a defined period—typically not exceeding one year. Revenue from these arrangements is recognized as the cloud hosting service is provided. Projects The Company also derives revenue from fees for separate, project-based services. The Company’s projects are typically short-term in nature and usually complete in less than 90 days. Project pricing is generally either fixed fee or time and material based. The Company recognizes revenue from these service arrangements in accordance with ASC 605. Projects are either sold as one deliverable, or as multiple deliverables with stand-alone For projects which have multiple deliverables, each with standalone value, the Company recognizes revenue based on ASC 605 and allocates the arrangement consideration based on the relative selling price of the deliverables. For project deliverables, the Company uses its best estimate of selling price (“BESP”) if vendor-specific Multiple element arrangements Multiple element arrangements may include customer rights to any combination of software, project deliverables, software as a service, maintenance and training. When more than one element is contained in a single arrangement, the Company first allocates total arrangement revenue based upon relative selling prices into two categories: (1) non-software components, such as services under projects not related to software licenses or software-as-a-service and (2) software components, such as software licenses, maintenance and support, and other software-related services. Revenue allocated to non-software services is recognized based on ASC 605 and the arrangement consideration is allocated based on the relative selling price of the deliverables. For non-software deliverables, the Company uses its best estimate of selling price (“BESP”) if vendor-specific objective evidence (“VSOE”) or third-party evidence of selling price (“TPE”) do not exist. Revenue allocated to products sold which meet the definition of software components is recognized based on software accounting guidance provided for in ASC 985-605. Under this guidance, most companies use the residual method to recognize revenue when a multiple element arrangement includes one or more software related elements to be delivered at a future date and VSOE of fair value of all undelivered elements exists (typically maintenance and other services), but does not exist for the delivered elements (typically the software). However, since the Company cannot establish VSOE for its undelivered elements, the entire software arrangement is deferred and recognized ratably over the contract (maintenance) period. This particularly includes the Company’s term-based licenses since the software license term and the maintenance term are co-terminus.
Foreign Currency Translation	Foreign Currency Translation The Company has foreign subsidiaries in the United Kingdom, France, Germany, Italy, Japan, Korea and China. Foreign subsidiary records are maintained in the local currency. Foreign currency effects are accounted for in accordance with ASC 830— Foreign Currency Matters Other than for its subsidiary in the United Kingdom, the functional currency for all of the Company’s subsidiaries is the respective local currency. The resulting gains and losses from translation are included as a component of other comprehensive income. Transaction gains and losses and re-measurement of assets and liabilities denominated in currencies other than an entity’s functional currency are included in other (expense) income, net. For the Company’s subsidiary in the United Kingdom, which is unable to generate sufficient cash flows in its local currency to sustain operational viability, all assets and liabilities are re-measured into United States dollars, with any resulting unrealized gains or losses being recorded as a component of other (expense) income, net. Foreign currency (loss) gain included in other (expense) income, net for the years ended January 31, 2016, 2015 and 2014 was $(322), $344 and $(83), respectively.
Concentration of Credit Risk and Significant Customers	Concentration of Credit Risk and Significant Customers Financial instruments that potentially subject the Company to concentration of credit risks are principally cash and cash equivalents and accounts receivable. The Company invests its cash and cash equivalents with high credit quality financial institutions, and consequently, the Company believes that such funds are subject to minimal credit risk. The Company maintains its cash in bank deposit accounts, which at times may exceed federally insured limits, but management believes that the deposits are not exposed to significant credit risk due to the financial position of the depository institutions in which those financial instruments are held. Concentrated credit risk with respect to accounts receivable is limited to large creditworthy customers. The Company periodically assesses the financial strength of its customers and believes that its accounts receivable credit risk exposure is minimal. The Company typically does not require collateral from its customers for sales on account. The Company has not experienced significant losses related to receivables from individual customers or groups of customers in any specific industry or geographic region. The following table provides information concerning customers that individually in the respective fiscal year accounted for greater than 10% of total revenues or 10% of accounts receivable, and their respective percentages of total revenues and accounts receivable, as of and for the years ended January 31, 2016, 2015 and 2014: Year Ended January 31, 2016 2015 2014 Percentage of Percentage of accounts receivable at fiscal year end Percentage of total revenues Percentage of accounts receivable at fiscal year end Percentage of total revenues Percentage of accounts receivable at fiscal year end Customer A * 14 % 10 % 16 % 12 % 21 % Customer B * 14 % * 17 % * * Customer C * 29 % * 16 % * 15 % Customer D * 10 % * 12 % * 14 % Customer E 12 % * * * * * * less than 10% Concentration of Other Risks The Company has one main data center provider, and several support providers (which handle overflow), to host or provide access to hardware for the Company’s OnDemand and ExaCLOUD application services to customers. The disruption of these services could have a material adverse effect on the Company’s business, financial position, and results of operations.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash The Company considers all highly liquid investments purchased with an original maturity of 90 days or less, that are not restricted as to withdrawal, to be the equivalent of cash for the purpose of consolidated balance sheet and statement of cash flows presentation. Cash equivalents consisted of money market accounts as of January 31, 2016 and 2015. The Company maintained $352 and $525 of restricted cash related to an operating lease at January 31, 2016 and 2015, respectively.
Accounts Receivable and Allowances for Doubtful Accounts	Accounts Receivable and Allowances for Doubtful Accounts Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for doubtful accounts is provided to the extent that specific accounts receivable are considered to be uncollectible, based on historical experience, known collection issues, and management’s evaluation of outstanding accounts receivable at the end of the year. Uncollectible amounts, if any, are written-off against the allowance after all collection efforts have been exhausted. The Company recorded no bad debt expense during fiscal years ended January 31, 2016 and 2015. During the fiscal year ended January 31, 2014, the Company recorded $21 of net bad debt expense relating to write-offs of uncollectible receivables. Based on management’s analysis of its outstanding accounts receivable, and customers’ creditworthiness and collection history, the Company concluded that an allowance was not necessary as of January 31, 2016 and 2015.
Property and Equipment, net	Property and equipment, net is stated at cost. Major renewals, additions and betterments are capitalized to property accounts while replacements, maintenance and repairs which do not improve or extend the lives of the respective assets are expensed in the period incurred. Upon retirement or sale, the cost of the assets disposed of and the related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in the consolidated statement of operations. Depreciation is computed using the straight-line method over the estimated useful life of each asset, generally as follows: Asset classification Estimated Useful Life Computer equipment 3-5 years Software 3 years Office equipment and furniture 3-7 years Leasehold improvements Shorter of useful life or remaining life of lease Leasehold improvements and assets acquired under capital leases are typically amortized using the straight-line method over the shorter of the estimated useful life of the asset or the term of the lease. However, assets acquired under capital leases that contain bargain purchase options that are typically exercised are amortized over the estimated useful life of the asset. Amortization of leasehold improvements and assets acquired under capital leases is included in depreciation expense.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of these assets is measured by comparison of their carrying amounts to the future undiscounted cash flows the assets are expected to generate. If any long-lived assets are considered to be impaired, the impairment recognized equals the amount by which the carrying value of the assets exceeds its estimated fair value. The Company did not identify any indicators of impairment of its long-lived assets during the fiscal years ended January 31, 2016 and 2015.
Research and Development Expenses	Research and Development Expenses Research and development expense includes costs incurred to develop intellectual property and are charged to expense as incurred. The costs for the development of new software and substantial enhancements to existing software are expensed as incurred until technological feasibility has been established, at which time any additional costs are capitalized. The Company has determined that technological feasibility is established at the time a working model of software is completed. Because the Company believes that, under its current process for developing software, completion of the software is essentially concurrent with the establishment of technological feasibility, no costs have been capitalized to date.
Internal-Use Software	Internal-Use Software Costs incurred in the research and development of the Company’s software products are expensed as incurred. Costs incurred during the application development stage of internal-use software projects, such as those used to develop internal systems, are capitalized. Capitalized costs include external consulting fees and payroll and payroll-related costs for employees in the Company’s development and information technology groups who are directly associated with, and who devote time to, the Company’s internal-use software projects during the application development stage. Capitalization begins when the planning stage is complete and the Company commits resources to the software project. Amortization of the asset commences when the software is complete and placed in service. The Company amortizes completed internal-use software over its estimated useful life. Costs incurred during the planning, training and post-implementation stages of the software development life-cycle are expensed as incurred. Costs related to upgrades and enhancements of existing internal-use software that increase the functionality of the software are also capitalized.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred. To date, the Company has not incurred significant advertising costs.
Income Taxes	Income Taxes Income taxes are accounted for in accordance with ASC 740, Income Taxes In determining the realizability of the net United States federal and state deferred tax assets, the Company considers numerous factors including historical profitability, estimated future taxable income, prudent and feasible tax planning strategies and the industry in which it operates. Management reassesses the realization of the deferred tax assets each reporting period, which resulted in a valuation allowance against the full amount of the Company’s United States net deferred tax assets being recorded in fiscal year 2015 and continuing to be recorded as of January 31, 2016 and 2015. To the extent that the financial results of the United States operations improve in the future and the deferred tax assets become more likely than not realizable, the Company will reduce the valuation allowance through earnings. The Company follows ASC 740-10-25 with regards to accounting for uncertain tax positions, which prescribes a threshold for the financial statement recognition and measurement of a tax position taken or expected to be taken within an income tax return. For each tax position, the enterprise must determine whether it is more likely than not that the position will be sustained upon examination based on the technical merits of the position, including resolution of any related appeals or litigation. A tax position that meets the more likely than not recognition threshold is then measured to determine the amount of benefit to recognize within the financial statements. No benefits may be recognized for tax positions that do not meet the more likely than not threshold. The Company’s intention is to indefinitely reinvest the total amount of its unremitted foreign earnings in the local international jurisdictions, except for instances where the Company can remit such earnings to the United States without an associated net tax cost. As a result, the Company currently does not provide for United States taxes on the unremitted earnings of its international subsidiaries.
Comprehensive Loss and Accumulated Other Comprehensive Loss	Comprehensive Loss and Accumulated Other Comprehensive Loss ASC 220, Comprehensive Income
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with ASC 718, Compensation—Stock Compensation ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures rates differ from those estimates. Forfeitures are estimated based on historical experience. The Company recognizes windfall tax benefits associated with the exercise of stock options or release of restricted stock units directly to stockholders’ equity only when realized. A windfall tax benefit occurs when the actual tax benefit realized by the Company upon an employee’s disposition of a share-based award exceeds the deferred tax asset, if any, associated with the award that we had recorded. When assessing whether a tax benefit relating to share-based compensation has been realized, the Company follows the “with-and-without” method. Under the with-and-without method, the windfall is considered realized and recognized for financial statement purposes only when an incremental benefit is provided after considering all other tax benefits including the Company’s net operating losses. The with-and-without method results in the windfall from share-based compensation awards always being effectively the last tax benefit to be considered. Consequently, the windfall attributable to share-based compensation will not be considered realized in instances where our net operating loss carryover (that is unrelated to windfalls) is sufficient to offset the current year’s taxable income before considering the effects of current-year windfalls.
Net Loss per Share	Net Loss per Share Net loss per share is computed using the weighted average number of shares of common stock outstanding during each period. Diluted amounts per share include the impact of the Company’s outstanding potential common shares, such as shares issuable upon exercise of in-the-money stock options or warrants or upon conversion of convertible preferred stock, when dilutive. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net loss income per common share.
