The Company and Summary of Sign

The Company and Summary of Significant Accounting Policies and Estimates	6 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
The Company and Summary of Significant Accounting Policies and Estimates	The Company and Summary of Significant Accounting Policies and Estimates Business Guidewire Software, Inc., a Delaware corporation, was incorporated on September 20, 2001. Guidewire Software, Inc., together with its subsidiaries (the “Company”), provides a technology platform which consists of three key elements: core transaction processing, data management and analytics, and digital engagement. It supports core insurance operations, including underwriting and policy administration, claim management and billing, enables new insights into data that can improve business decision making and supports digital sales, service and claims experiences for policyholders, agents, and other key stakeholders. The Company’s customers include insurance carriers for property and casualty insurance. Basis of Presentation The accompanying unaudited condensed consolidated financial statements and accompanying notes include the Company and its wholly-owned subsidiaries, and reflect all adjustments (all of which are normal and recurring in nature) that, in the opinion of management, are necessary for a fair presentation of the interim periods presented. All inter-company balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and related notes, together with management’s discussion and analysis of financial condition and results of operations, presented in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2015 . There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s consolidated financial statements for the fiscal year ended July 31, 2015 included in the Company’s Annual Report on Form 10-K. Use of Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Significant items subject to such estimates include, but are not limited to, revenue recognition, the useful lives of property and equipment and intangible assets, allowance for doubtful accounts, valuation allowance for deferred tax assets, stock-based compensation, annual bonus attainment, income tax uncertainties, valuation of goodwill and intangible assets, and contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors; however, actual results could differ significantly from these estimates. Cash and Cash Equivalents Cash and cash equivalents are comprised of cash and highly liquid investments with remaining maturities of 90 days or less at the date of purchase. Cash equivalents consist of commercial paper and money market funds. Investments Management determines the appropriate classification of investments at the time of purchase based upon management’s intent with regard to such investments. All investments are held as available-for-sale investments. The Company classifies investments as short-term when they have remaining contractual maturities of one year or less from the balance sheet date, and as long-term when the investments have remaining contractual maturities of more than one year from the balance sheet date. All investments are recorded at fair value with unrealized holding gains and losses included in accumulated other comprehensive loss. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, investments and accounts receivable. The Company maintains its cash, cash equivalents and investments with high quality financial institutions. The Company is exposed to credit risk for cash held in financial institutions in the event of a default to the extent that such amounts recorded on the balance sheet are in excess of amounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”). No customer individually accounted for 10% or more of the Company’s revenues for the three and six months ended January 31, 2016 or 2015 . No customer individually accounted for 10% or more of the Company’s total accounts receivable as of January 31, 2016 or as of July 31, 2015 . Revenue Recognition The Company enters into arrangements to deliver multiple products or services (multiple-elements). The Company applies software revenue recognition rules and allocates the total revenues among elements based on vendor-specific objective evidence (“VSOE”) of fair value of each element. The Company recognizes revenue on a net basis excluding indirect taxes, such as sales tax and value added tax collected from customers and remitted to government authorities. Revenues are derived from three sources: (i) License fees related to term (or time-based) licenses, perpetual software licenses, and other; (ii) Maintenance fees related to email and phone support, bug fixes and unspecified software updates and upgrades released when, and if, available during the maintenance term; and (iii) Services fees related to professional services related to implementation of our software, reimbursable travel and training. Revenues are recognized when all of the following criteria are met: • Persuasive evidence of an arrangement exists. Evidence of an arrangement consists of a written contract signed by both the customer and management prior to the end of the period. • Delivery or performance has occurred . The Company’s software is delivered electronically to the customer. Delivery is considered to have occurred when the Company provides the customer access to the software along with login credentials. • Fees are fixed or determinable. The Company assesses whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. Term and perpetual license fees are not considered to be fixed or determinable until they become due. Fees from term licenses are invoiced in annual or quarterly installments over the term of the agreement beginning on the effective date of the license. A significant majority are invoiced annually. Perpetual license fees are generally due between 30 and 60 days from delivery of software, however in certain cases extended payment terms may be offered. • Collectability is probable. Collectability is assessed on a customer-by-customer basis, based primarily on creditworthiness as determined by credit checks and analysis, as well as customer payment history. Payment terms generally range from 30 to 90 days from invoice date. If it is determined prior to revenue recognition that collection of an arrangement fee is not probable, revenues are deferred until collection becomes probable or cash is collected, assuming all other revenue recognition criteria are satisfied. VSOE of fair value does not exist for the Company’s software licenses; therefore, the Company allocates revenues to software licenses using the residual method. Under the residual method, the amount recognized for license fees is the difference between the total fixed and determinable fees and the VSOE of fair value for the undelivered elements under the arrangement. The VSOE of fair value for elements of an arrangement is based upon the normal pricing and discounting practices for those elements when sold separately. VSOE of fair value for maintenance is established using the stated maintenance renewal rate in the customer’s contract. For term licenses with duration of one year or less, no VSOE of fair value for maintenance exists. VSOE of fair value for services is established if a substantial majority of historical stand-alone selling prices for a service fall within a reasonably narrow price range. If the undelivered elements are all service elements and VSOE of fair value does not exist for one or more service element, the total arrangement fee is recognized ratably over the longest service period starting at software delivery, assuming all the related services have been made available to the customer. In certain offerings sold as fixed fee arrangements, the Company recognizes services revenues on a proportional performance basis as performance obligations are completed by using the ratio of labor hours to date as an input measure compared to total estimated labor hours for the consulting services. In cases where professional services are deemed to be essential to the functionality of the software, the arrangement is accounted for using contract accounting until the essential services are complete. If reliable estimates of total project costs can be made, the Company applies the percentage-of-completion method whereby percentage toward completion is measured by using the ratio of service billings to date compared to total estimated service billings for the consulting services. Service billings approximate labor hours as an input measure since they are generally billed monthly on a time and material basis. The fees related to the maintenance are recognized over the period the maintenance is provided. As noted above, the Company generally invoices fees for licenses and maintenance in annual or quarterly installments payable in advance. Deferred revenues represent amounts, which are billed to or collected from customers for which one or more of the revenue recognition criteria have not been met. The deferred revenues balance does not represent the total contract value of annual or multi-year, non-cancellable arrangements. Income Taxes Income taxes are accounted for under the asset and liability method. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement carrying amounts of existing assets and liabilities by using enacted tax rates in effect for the year in which the difference is expected to reverse. Deferred tax assets related to excess tax benefits are recorded when utilized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance against deferred tax assets is recorded when it is more likely than not that some portion or all of such deferred tax assets will not be realized and is based on the positive and negative evidence about the future including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. As described below in Recent Accounting Pronouncements, we adopted ASU 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes, effective January 31, 2016 on a prospective basis. As a result, all deferred tax assets and liabilities are classified as non-current as of January 31, 2016. Prior to the adoption, deferred tax assets and liabilities were classified as either current or non-current based on the related asset or liability. The effective tax rate in any given financial statement period may differ materially from the statutory rate. These differences may be caused by changes in the mix and level of income or losses, changes in the expected outcome of audits, change in tax regulations, or changes in the deferred tax valuation allowance. The Company records interest and penalties related to unrecognized tax benefits as income tax expense in its condensed consolidated statement of operations. Stock-Based Compensation The Company recognizes compensation expense related to its stock options and restricted stock units (“RSUs”) granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The awards are subject to time-based vesting, which generally occurs over a period of 4 years . Option awards expire 10 years from the grant date. The Company estimates the grant date fair value, and the resulting stock-based compensation expense, of the Company’s stock options using the Black-Scholes option-pricing model. The Company recognizes the fair value of stock-based compensation for awards which contain only service conditions on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. The Company recognizes the compensation cost for awards which contain performance conditions based upon the probability of that performance condition being met, net of estimated forfeitures, using the graded method. Recent Accounting Pronouncements Balance Sheet Classification of Deferred Taxes In November 2015, the FASB issued ASU 2015-17, Income Taxes (Subtopic 740-10) which provides guidance for balance sheet classification of deferred taxes. This ASU requires that deferred tax assets and liabilities be classified as non-current on the balance sheet. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this ASU. ASU 2015-17 is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods with earlier application permitted as of the beginning of an interim or annual reporting period. The amendments in this update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We adopted this guidance on a prospective basis effective January 31, 2016 and accordingly, classified all deferred taxes as non-current on our balance sheet as of January 31, 2016. Under the prospective method, the prior period balance sheet was not retrospectively adjusted. Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides guidance for revenue recognition. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. In July 2015, the FASB deferred the effective date to annual reporting periods and interim periods within fiscal years beginning after December 15, 2017. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The standard will be effective for the Company beginning August 1, 2018 and permits the use of either the retrospective or cumulative effect transition method. We have not yet selected a transition method and continue to evaluate all the potential impacts that this guidance will have on our consolidated financial statements. We have, however, begun modifying the way we engage with customers to reduce the impact we currently believe is likely to occur under the new standard which will be effective in fiscal 2019.

The unrealized losses on its available-for-sale securities were primarily a result of changes in interest rates subsequent to the initial purchase of these securities. The Company does not intend to sell, nor believe it will need to sell, these securities before recovering the associated unrealized losses. The Company does not consider any portion of the unrealized losses at January 31, 2016 to be an other-than-temporary impairment, nor are any unrealized losses considered to be credit losses. The Company has recorded the securities at fair value in its condensed consolidated balance sheets, with unrealized gains and losses reported as a component of accumulated other comprehensive loss. The amounts of realized gains and losses reclassified into earnings are based on the specific identification of the securities sold. The realized gains and losses from sales of securities in the periods presented were not significant. The following table summarizes the contractual maturities of the Company’s investments measured at fair value as of January 31, 2016 : Less Than 12 Months 12 to 36 Months Total (in thousands) U.S. agency securities $ 79,777 $ 10,610 $ 90,387 Commercial paper 105,055 — 105,055 Corporate bonds 192,698 70,971 263,669 U.S. government bonds 64,154 23,239 87,393 Foreign government bonds 8,595 — 8,595 Money market funds 93,897 — 93,897 Non-marketable convertible note $ — $ 5,000 $ 5,000 Total $ 544,176 $ 109,820 $ 653,996 Fair Value Measurement The current accounting guidance for fair value measurements defines a three-level valuation hierarchy for disclosures as follows: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Inputs other than quoted prices included within Level 1 that are observable, unadjusted quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data; and Level 3—Unobservable inputs that are supported by little or no market activity, which require the Company to develop its own assumptions. During December 2015, the Company invested $5 million in a convertible note issued by a privately-held company that does not have a readily determinable market value. The convertible note is recorded in long-term investments on the condensed consolidated balance sheet at fair value. The convertible note is classified within Level 3 as it is valued using significant unobservable inputs or data in an inactive market, and the valuation requires management judgment due to the absence of a market price and inherent lack of liquidity.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies There has been no material change in the Company’s contractual obligations and commitments other than in the ordinary course of business since the Company’s fiscal year ended July 31, 2015 . See the Annual Report on Form 10-K for the fiscal year ended July 31, 2015 for additional information regarding the Company’s contractual obligations. Leases The Company leases certain facilities and equipment under operating leases. On December 5, 2011, the Company entered into a seven -year lease for a facility to serve as its corporate headquarters, located in Foster City, California, for approximately 97,674 square feet of space which commenced on August 1, 2012. In connection with this lease, the Company opened an unsecured letter of credit with Silicon Valley Bank for $1.2 million . On July 1, 2015 , the unsecured letter of credit was reduced to $0.4 million in accordance with the lease agreement. Lease expense for all worldwide facilities and equipment, which is being recognized on a straight-line basis over terms of the various leases, was $1.4 million and $ 2.8 million for the three and six months ended January 31, 2016 , respectively, and was $1.6 million and $3.2 million for the three and six months ended January 31, 2015 , respectively. Letters of Credit The Company had two outstanding letters of credit required to secure contractual commitments and prepayments as of January 31, 2016 and July 31, 2015 , respectively. In addition to the unsecured letter of credit for the building lease, the Company had an unsecured letter of credit agreement related to a customer arrangement for Polish Zloty 10.0 million (approximately $2.5 million as of January 31, 2016 ) to secure contractual commitments and prepayments. No amounts were outstanding under the Company’s unsecured letters of credit as of January 31, 2016 or July 31, 2015 . Legal Proceedings From time to time, the Company is involved in various legal proceedings and receives claims, arising from the normal course of business activities. The Company accrues for estimated losses in the accompanying condensed consolidated financial statements for matters with respect to which the Company believes the likelihood of an adverse outcome is probable and the amount of the loss is reasonably estimable. Indemnification The Company sells software licenses and services to its customers under contracts (“Software License”). Each Software License contains the terms of the contractual arrangement with the customer and generally includes certain provisions for defending the customer against any claims that the Company’s software infringes upon a patent, copyright, trademark, or other proprietary right of a third party. Software Licenses also indemnify the customer against losses, expenses, and liabilities from damages that may be assessed against the customer in the event the Company’s software is found to infringe upon such third party rights. The Company has not had to reimburse any of its customers for losses related to indemnification provisions and no material claims against the Company were outstanding as of January 31, 2016 or July 31, 2015 . For several reasons, including the lack of prior indemnification claims and the lack of a monetary liability limit for certain infringement cases under various Software Licenses, the Company cannot estimate the amount of potential future payments, if any, related to indemnification provisions. The Company has also agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of these persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by the Company, arising out of that person’s services as the Company’s director or officer or that person’s services provided to any other company or enterprise at the Company’s request. The Company maintains director and officer insurance coverage that may enable the Company to recover a portion of any future amounts paid.

Aggregate intrinsic value for exercised options represents the difference between the Company’s stock price at date of exercise and the exercise price. Valuation of Awards The assumptions used to estimate the grant date fair value of options and the estimated weighted average grant date fair value of options for the six months ended January 31, 2016 and 2015 are as follows: Six Months Ended January 31, 2016 2015 Expected life (in years) 4.9 6.0 Risk-free interest rate 1.49% 1.92% Expected volatility 38.8% 45.1% Expected dividend yield —% —% Weighted average grant date fair value of options $19.18 $20.53 There were no options granted during the three months ended January 31, 2016 and 2015 . Beginning fiscal year 2016, the Company began estimating the expected term using a historical data method, instead of the simplified method, because it now has sufficient data to estimate the stock option exercise period based on its historical stock option activity and employee termination data. In addition, the Company began estimating the volatility using its own common stock data, instead of volatility of several comparable public listed peers, as the Company now has sufficient trading history of its stock. Common Stock Reserved for Issuance As of January 31, 2016 and July 31, 2015 , the Company was authorized to issue 500,000,000 shares of common stock with a par value of $0.0001 per share, and 72,054,151 and 71,005,738 shares of common stock were issued and outstanding, respectively.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company recognized an income tax expense of $6.4 million and an income tax benefit of $0.1 million for the three and six months ended January 31, 2016 , and income tax benefits of $1.0 million and $1.6 million for the three and six months ended January 31, 2015, respectively. The effective tax rates of 87.5% and 7.1% for the three and six months ended January 31, 2016 differ from the statutory U.S. federal income tax rate of 35% mainly due to incentive stock options tax deductions, permanent differences for stock-based compensation, the impact of state income taxes, the tax rate differences between the United States and foreign countries, and research and development credits. The Company provides U.S. income taxes on the earnings of foreign subsidiaries, unless the subsidiaries’ earnings are considered indefinitely reinvested outside the United States. As of January 31, 2016 , U.S. income taxes were not provided for on the cumulative total of $31.0 million undistributed earnings from certain foreign subsidiaries. As of January 31, 2016 , the unrecognized deferred tax liability for these earnings was approximately $10.2 million . During the six months ended January 31, 2016 , the decrease in unrecognized tax benefits from the beginning of the period was $0.9 million . Accordingly, as of January 31, 2016 , the Company had unrecognized tax benefits of $3.9 million that, if recognized, would affect the Company’s effective tax rate.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	Business Guidewire Software, Inc., a Delaware corporation, was incorporated on September 20, 2001. Guidewire Software, Inc., together with its subsidiaries (the “Company”), provides a technology platform which consists of three key elements: core transaction processing, data management and analytics, and digital engagement. It supports core insurance operations, including underwriting and policy administration, claim management and billing, enables new insights into data that can improve business decision making and supports digital sales, service and claims experiences for policyholders, agents, and other key stakeholders. The Company’s customers include insurance carriers for property and casualty insurance.
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements and accompanying notes include the Company and its wholly-owned subsidiaries, and reflect all adjustments (all of which are normal and recurring in nature) that, in the opinion of management, are necessary for a fair presentation of the interim periods presented. All inter-company balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in annual financial statements prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been condensed or omitted under the rules and regulations of the Securities and Exchange Commission (“SEC”). These unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s financial statements and related notes, together with management’s discussion and analysis of financial condition and results of operations, presented in the Company’s Annual Report on Form 10-K for the fiscal year ended July 31, 2015 . There have been no changes in the Company’s significant accounting policies from those that were disclosed in the Company’s consolidated financial statements for the fiscal year ended July 31, 2015 included in the Company’s Annual Report on Form 10-K.
Use of Estimates	Use of Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events that affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenues and expenses. Significant items subject to such estimates include, but are not limited to, revenue recognition, the useful lives of property and equipment and intangible assets, allowance for doubtful accounts, valuation allowance for deferred tax assets, stock-based compensation, annual bonus attainment, income tax uncertainties, valuation of goodwill and intangible assets, and contingencies. These estimates and assumptions are based on management’s best estimates and judgment. Management regularly evaluates its estimates and assumptions using historical experience and other factors; however, actual results could differ significantly from these estimates.
Cash. Cash Equivalents and Investments	Cash and Cash Equivalents Cash and cash equivalents are comprised of cash and highly liquid investments with remaining maturities of 90 days or less at the date of purchase. Cash equivalents consist of commercial paper and money market funds. Investments Management determines the appropriate classification of investments at the time of purchase based upon management’s intent with regard to such investments. All investments are held as available-for-sale investments. The Company classifies investments as short-term when they have remaining contractual maturities of one year or less from the balance sheet date, and as long-term when the investments have remaining contractual maturities of more than one year from the balance sheet date. All investments are recorded at fair value with unrealized holding gains and losses included in accumulated other comprehensive loss.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents, investments and accounts receivable. The Company maintains its cash, cash equivalents and investments with high quality financial institutions. The Company is exposed to credit risk for cash held in financial institutions in the event of a default to the extent that such amounts recorded on the balance sheet are in excess of amounts that are insured by the Federal Deposit Insurance Corporation (“FDIC”).
Revenue Recognition	Revenue Recognition The Company enters into arrangements to deliver multiple products or services (multiple-elements). The Company applies software revenue recognition rules and allocates the total revenues among elements based on vendor-specific objective evidence (“VSOE”) of fair value of each element. The Company recognizes revenue on a net basis excluding indirect taxes, such as sales tax and value added tax collected from customers and remitted to government authorities. Revenues are derived from three sources: (i) License fees related to term (or time-based) licenses, perpetual software licenses, and other; (ii) Maintenance fees related to email and phone support, bug fixes and unspecified software updates and upgrades released when, and if, available during the maintenance term; and (iii) Services fees related to professional services related to implementation of our software, reimbursable travel and training. Revenues are recognized when all of the following criteria are met: • Persuasive evidence of an arrangement exists. Evidence of an arrangement consists of a written contract signed by both the customer and management prior to the end of the period. • Delivery or performance has occurred . The Company’s software is delivered electronically to the customer. Delivery is considered to have occurred when the Company provides the customer access to the software along with login credentials. • Fees are fixed or determinable. The Company assesses whether a fee is fixed or determinable at the outset of the arrangement, primarily based on the payment terms associated with the transaction. Term and perpetual license fees are not considered to be fixed or determinable until they become due. Fees from term licenses are invoiced in annual or quarterly installments over the term of the agreement beginning on the effective date of the license. A significant majority are invoiced annually. Perpetual license fees are generally due between 30 and 60 days from delivery of software, however in certain cases extended payment terms may be offered. • Collectability is probable. Collectability is assessed on a customer-by-customer basis, based primarily on creditworthiness as determined by credit checks and analysis, as well as customer payment history. Payment terms generally range from 30 to 90 days from invoice date. If it is determined prior to revenue recognition that collection of an arrangement fee is not probable, revenues are deferred until collection becomes probable or cash is collected, assuming all other revenue recognition criteria are satisfied. VSOE of fair value does not exist for the Company’s software licenses; therefore, the Company allocates revenues to software licenses using the residual method. Under the residual method, the amount recognized for license fees is the difference between the total fixed and determinable fees and the VSOE of fair value for the undelivered elements under the arrangement. The VSOE of fair value for elements of an arrangement is based upon the normal pricing and discounting practices for those elements when sold separately. VSOE of fair value for maintenance is established using the stated maintenance renewal rate in the customer’s contract. For term licenses with duration of one year or less, no VSOE of fair value for maintenance exists. VSOE of fair value for services is established if a substantial majority of historical stand-alone selling prices for a service fall within a reasonably narrow price range. If the undelivered elements are all service elements and VSOE of fair value does not exist for one or more service element, the total arrangement fee is recognized ratably over the longest service period starting at software delivery, assuming all the related services have been made available to the customer. In certain offerings sold as fixed fee arrangements, the Company recognizes services revenues on a proportional performance basis as performance obligations are completed by using the ratio of labor hours to date as an input measure compared to total estimated labor hours for the consulting services. In cases where professional services are deemed to be essential to the functionality of the software, the arrangement is accounted for using contract accounting until the essential services are complete. If reliable estimates of total project costs can be made, the Company applies the percentage-of-completion method whereby percentage toward completion is measured by using the ratio of service billings to date compared to total estimated service billings for the consulting services. Service billings approximate labor hours as an input measure since they are generally billed monthly on a time and material basis. The fees related to the maintenance are recognized over the period the maintenance is provided.
Deferred Revenues	As noted above, the Company generally invoices fees for licenses and maintenance in annual or quarterly installments payable in advance. Deferred revenues represent amounts, which are billed to or collected from customers for which one or more of the revenue recognition criteria have not been met. The deferred revenues balance does not represent the total contract value of annual or multi-year, non-cancellable arrangements.
Income Taxes	Income Taxes Income taxes are accounted for under the asset and liability method. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement carrying amounts of existing assets and liabilities by using enacted tax rates in effect for the year in which the difference is expected to reverse. Deferred tax assets related to excess tax benefits are recorded when utilized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance against deferred tax assets is recorded when it is more likely than not that some portion or all of such deferred tax assets will not be realized and is based on the positive and negative evidence about the future including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies, and results of recent operations. As described below in Recent Accounting Pronouncements, we adopted ASU 2015-17, Income Taxes: Balance Sheet Classification of Deferred Taxes, effective January 31, 2016 on a prospective basis. As a result, all deferred tax assets and liabilities are classified as non-current as of January 31, 2016. Prior to the adoption, deferred tax assets and liabilities were classified as either current or non-current based on the related asset or liability. The effective tax rate in any given financial statement period may differ materially from the statutory rate. These differences may be caused by changes in the mix and level of income or losses, changes in the expected outcome of audits, change in tax regulations, or changes in the deferred tax valuation allowance. The Company records interest and penalties related to unrecognized tax benefits as income tax expense in its condensed consolidated statement of operations.
Stock-Based Compensation	Stock-Based Compensation The Company recognizes compensation expense related to its stock options and restricted stock units (“RSUs”) granted to employees based on the estimated fair value of the awards on the date of grant, net of estimated forfeitures. The awards are subject to time-based vesting, which generally occurs over a period of 4 years . Option awards expire 10 years from the grant date. The Company estimates the grant date fair value, and the resulting stock-based compensation expense, of the Company’s stock options using the Black-Scholes option-pricing model. The Company recognizes the fair value of stock-based compensation for awards which contain only service conditions on a straight-line basis over the requisite service period, which is generally the vesting period of the respective awards. The Company recognizes the compensation cost for awards which contain performance conditions based upon the probability of that performance condition being met, net of estimated forfeitures, using the graded method.
Recent Accounting Pronouncement	Recent Accounting Pronouncements Balance Sheet Classification of Deferred Taxes In November 2015, the FASB issued ASU 2015-17, Income Taxes (Subtopic 740-10) which provides guidance for balance sheet classification of deferred taxes. This ASU requires that deferred tax assets and liabilities be classified as non-current on the balance sheet. The current requirement that deferred tax liabilities and assets of a tax-paying component of an entity be offset and presented as a single amount is not affected by the amendments in this ASU. ASU 2015-17 is effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods with earlier application permitted as of the beginning of an interim or annual reporting period. The amendments in this update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. We adopted this guidance on a prospective basis effective January 31, 2016 and accordingly, classified all deferred taxes as non-current on our balance sheet as of January 31, 2016. Under the prospective method, the prior period balance sheet was not retrospectively adjusted. Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides guidance for revenue recognition. This ASU affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of non-financial assets. This ASU will supersede the revenue recognition requirements in Topic 605, Revenue Recognition, and most industry-specific guidance. This ASU also supersedes some cost guidance included in Subtopic 605-35, Revenue Recognition-Construction-Type and Production-Type Contracts. In July 2015, the FASB deferred the effective date to annual reporting periods and interim periods within fiscal years beginning after December 15, 2017. Early adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The standard will be effective for the Company beginning August 1, 2018 and permits the use of either the retrospective or cumulative effect transition method. We have not yet selected a transition method and continue to evaluate all the potential impacts that this guidance will have on our consolidated financial statements. We have, however, begun modifying the way we engage with customers to reduce the impact we currently believe is likely to occur under the new standard which will be effective in fiscal 2019.
