The Company and Summary of Sign

The Company and Summary of Significant Accounting Policies and Estimates	12 Months Ended
	Jul. 31, 2017
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 Company 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. The Company’s technology platform supports core insurance operations, including underwriting, 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 are primarily insurance carriers for property and casualty insurance. Basis of Presentation and Consolidation Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Guidewire Software, Inc. and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of the accompanying 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 from these estimates. Foreign Currency The functional currency of the Company’s foreign subsidiaries is their respective local currency. The Company translates all assets and liabilities of foreign subsidiaries to U.S. dollars at the current exchange rate as of the applicable balance sheet date. Revenues and expenses are translated at the average exchange rate prevailing during the period in which the transactions occur. The effects of foreign currency translations are recorded in accumulated other comprehensive income/loss as a separate component of stockholders’ equity in the accompanying consolidated statements of stockholders’ equity. Transaction gains and losses from foreign currency transactions that arise from exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are recorded as other income (expense) in the consolidated statements of operations. 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 primarily 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 classified as available-for-sale. 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) income. Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the related assets. Maintenance and repairs that do not extend the life or improve an asset are expensed in the period incurred. The estimated useful lives of property and equipment are as follows: Computer hardware 3 years Purchased software 3 years Furniture and fixtures 3 years Leasehold improvements Shorter of the lease term or estimated useful life Software Development Costs Certain software development costs incurred subsequent to the establishment of technological feasibility are subject to capitalization and amortized over the estimated lives of the related products. Technological feasibility is established upon completion of a working model. Through July 31, 2017, costs incurred subsequent to the establishment of technological feasibility have not been material, and therefore, all software development costs have been charged to research and development expense in the accompanying consolidated statements of operations as incurred. For qualifying costs incurred for computer software developed for internal use, the Company begins to capitalize its costs to develop software when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. These capitalized costs are amortized to expense over the estimated useful life of the related asset, generally estimated to be three years. Costs incurred prior to meeting these capitalization criteria and costs incurred for training and maintenance are expensed as incurred and recorded in research and development expense on the Company’s consolidated statements of operations. Capitalized software development costs are recorded in property and equipment on the Company’s consolidated balance sheet as of July 31, 2017. Business Combinations The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. Goodwill is calculated as the difference between the acquisition-date fair value of the consideration transferred and the values assigned to the assets acquired and liabilities assumed. The Company’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and subject to refinement and, as a result, actual results may differ from estimates. During the measurement period, which may be up to one year from the acquisition date, if new information is obtained about facts and circumstances that existed as of the acquisition date, the Company may record adjustments to the fair value of these assets and liabilities, with the corresponding offset to goodwill. During the year ended July 31, 2016, the Company adopted ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments (Topic 805)” (“ASU 2015-16”), which requires the cumulative impact of measurement period adjustments (including the impact on prior periods) to be recognized in the reporting period in which the adjustments are identified. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s consolidated statements of operations. Impairment of Long-Lived Assets, Intangible Assets and Goodwill The Company evaluates its long-lived assets, consisting of property and equipment and intangible assets, for indicators of possible impairment when events or changes in circumstances indicate that the carrying amount of certain assets may not be recoverable. Impairment exists if the carrying amounts of such assets exceed the estimates of future net undiscounted cash flows expected to be generated by such assets. Should impairment exist, the impairment loss would be measured based on the excess carrying value of the assets over the estimated fair value of the assets. The Company has not written down any of its long-lived assets as a result of impairment during any of the periods presented. The Company tests goodwill for impairment annually during the fourth quarter of each fiscal year and in the interim whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. The Company evaluates qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. In performing the qualitative assessment, the Company considers events and circumstances, including but not limited to, macroeconomic conditions, industry and market considerations, cost factors, overall financial performance, changes in management or key personnel, changes in strategy, changes in customers, changes in the composition or carrying amount of a reporting unit’s net assets and changes in the price of the Company’s common stock. If, after assessing the totality of events or circumstances, the Company determines that it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then the two-step goodwill impairment test is not performed. There have been no goodwill impairments during any of the periods presented. 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 years ended July 31, 2017 , 2016 and 2015 . As of July 31, 2017 , one customer accounted for 11% of the Company’s total accounts receivable. As of July 31, 2016, No customer individually accounted for 10% or more of the Company’s total accounts receivable. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at invoiced amounts, net of the Company’s estimated allowances for doubtful accounts. The allowance for doubtful accounts is estimated based on an assessment of the Company’s ability to collect on customer accounts receivable, and there is judgment involved in such assessment. The Company regularly reviews the allowance by considering relevant factors such as historical experience, industry data, credit quality, age of accounts receivable balances, customers’ financial condition and current economic conditions that may affect a customer’s ability to pay. The Company has had no allowance for doubtful accounts in any of the periods presented. The Company’s accounts receivable are not collateralized by any security. Revenue Recognition The Company enters into arrangements to deliver multiple products or services (multiple-elements). For a substantial majority of its sales, the Company applies software revenue recognition rules and allocates the total revenues among elements based on vendor-specific objective evidence (“VSOE”) of the 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 software subscription models including those from recently acquired companies; (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 from professional services related to implementation of the Company’s 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. 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. Generally, the Company offers extended payment terms to its customers for term licenses. As a result, term license fees are not considered to be fixed and determinable until they become due or payment is received. • 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. Substantially all of the Company’s professional services engagements are billed on a time and materials basis. Services are typically not considered to be essential to the functionality of the software and the related revenues and costs are recognized in the period incurred. In select situations, the Company will contract its professional services on a fixed fee basis. In these situations, if reliable estimates of total project costs are available, the Company recognizes services revenues on a proportional performance basis as the 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. If reliable estimates of total project costs cannot be made, the zero gross margin or the completed contract method is applied to revenues and direct costs. Under the zero gross margin method, revenues recognized are limited to the direct costs incurred for the implementation services. Under the completed contract method, revenues and direct costs are deferred until the project is complete. When the zero gross margin method is applied for lack of reliable project estimates and subsequently project estimates become reliable, the Company switches to the percentage-of-completion method, resulting in a cumulative effect adjustment for deferred license revenues to the extent of progress toward completion, and the related portion of the deferred professional service margin is recognized in full as revenues. In the limited 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. The Company sells some of its software licenses on a subscription basis and the related revenues are recognized ratably over the term of the arrangement typically upon provisioning the products. As noted above, the Company generally invoices fees for licenses and maintenance to its customers in annual or quarterly installments payable in advance. Deferred revenues represent amounts, which are billed to or collected from creditworthy 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. Sales Commissions Sales commissions are recognized as an expense when earned by the sales representative, generally occurring at the time the customer order is signed. Substantially all of the effort by the sales force is expended through the time of closing the sale, with limited to no involvement thereafter. Warranties The Company generally provides a warranty for its software products and services to its customers for periods ranging from 3 to 12 months . The Company’s software products are generally warranted to be free of defects in materials and workmanship under normal use and to substantially perform as described in published documentation. The Company’s services are generally warranted to be performed in a professional manner and to materially conform to the specifications set forth in the related customer contract. In the event there is a failure of such warranties, the Company generally will correct the problem or provide a reasonable workaround or replacement product. If the Company cannot correct the problem or provide a workaround or replacement product, then the customer’s remedy is generally limited to refund of the fees paid for the nonconforming product or services. Warranty expense has been insignificant to date. Advertising Costs Advertising costs are expensed as incurred and amounts incurred were not material during the years ended July 31, 2017 , 2016 and 2015 . Stock-Based Compensation The Company accounts for stock-based compensation using the fair value method, which requires the Company to measure the stock-based compensation based on the grant-date fair value of the awards and recognize the compensation expense over the requisite service period. The Company recognizes compensation expense net of estimated forfeitures. To date, the Company has granted stock options, time-based restricted stock units (“RSUs”), performance-based restricted stock units (“PSUs”), and beginning in the first quarter of fiscal 2017, restricted stock units that may be earned subject to the Company’s total shareholder return ranking relative to the software companies in the S&P Software and Services Select Industry Index for a specified performance period or specified performance periods, service periods, and in select cases, subject to certain performance conditions (“TSR PSUs”). The Company recognizes compensation expense 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 that contain either a performance condition, market conditions, or both using the graded vesting method. The fair value of the Company’s RSUs and PSUs equals the market value of the Company’s common stock on the date of grant. The Company estimates the grant date fair value of the Company’s stock options using the Black-Scholes option-pricing model. These awards are subject to time-based vesting, which generally occurs over a period of four years. The fair value of the Company’s TSR PSUs are estimated at the grant date using a Monte Carlo simulation method. The assumptions utilized in this simulation require judgments and estimates. Changes in these inputs and assumptions could affect the measurement of the estimated fair value of the related compensation expense. Compensation expense associated with these TSR PSUs will be recognized over the vesting period regardless of whether the market condition is ultimately satisfied, however, the expense will be reversed if a grantee terminates prior to satisfying the requisite service period. For TSR PSUs containing an additional performance condition, a portion of the expense will fluctuate depending on the achievement of the performance conditions. All TSR PSUs will vest at the end of a three-year period. 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. All deferred tax assets and liabilities are classified as non-current on its consolidated financial statements. 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. 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 tax audits, changes 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 consolidated statement of operations. Recent Accounting Pronouncements Improvements on Employee Share-Based Payment Accounting In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Improvements on Employee Share-Based Payment Accounting (Topic 718) (“ASU 2016-09”), which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance requires all of the tax effects related to share based payments to be recorded through the income statement. The guidance also removes the present requirement to delay recognition of a windfall tax benefit until it reduces current taxes payable; instead it is recognized at the time of settlement, subject to normal valuation allowance consideration. The standard is effective for public business entities for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. Early adoption is permitted. The Company will adopt this standard effective on August 1, 2017. Upon adoption of this guidance the Company will change its accounting policy to account for forfeitures for share based awards as they occur and will record a cumulative effect adjustment to opening retained earnings. The amendments related to accounting for previously unrecognized excess tax benefits as deferred tax assets will be adopted on a modified retrospective basis with a cumulative effect adjustment to opening retained earnings, subject to valuation allowance considerations that we are still evaluating. Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), 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. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”), deferring the effective date of this standard. As a result, the ASU and related amendments will be effective for the Company for its fiscal year beginning August 1, 2018, including interim periods within that fiscal year. Early adoption is permitted, but not before the original effective date of the ASU, August 1, 2017. Subsequently, the FASB issued ASU No. 2016-08, Principal Versus Agent Consideration (or Reporting Revenue Gross versus Net) (“ASU 2016-08”) in March 2016, ASU No. 2016-10, Identifying Performance Obligations and Licensing in April 2016, and ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients in May 2016. These amendments clarified certain aspects of Topic 606 and have the same effective date as ASU 2014-09. The Company will adopt these ASUs (collectively, Topic 606) on August 1, 2018. Topic 606 permits two methods of adoption: retrospectively to each prior reporting period presented (the “Full Retrospective Method”), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the “Modified Retrospective Method”). The Company currently intends to apply the Modified Retrospective Method. The Company has evaluated the potential impact of Topic 606 on its revenue recognition policy and practices and has concluded that Topic 606 will impact the pattern of its revenue recognition associated with its software licenses. The Company’s term licenses require payments to be made annually or quarterly in advance and are subject to extended payment terms. Currently, revenues associated with the payment for term software licenses are recognized in the earlier of the period in which the payments are due or are actually made. Under Topic 606, the Company will be required to recognize the revenue associated with such payments not when they are made or due, but when control of the software license is transferred to the customer, which occurs at or near the time a contract with a customer is executed. As a result, under Topic 606, all contractually obligated payments under a term license that the Company reasonably expects to collect would be recognized upon delivery. In conjunction with its evaluation of this new standard, the Company began revising its contracting practices and amending existing agreements with certain customers primarily by shortening the initial, non-refundable term of its licenses. Since fiscal 2016, a substantial majority of new contracts feature a two-year initial term with subsequent one-year auto renewal options. The Company has engaged with its existing and prospective customers on its new licensing model. The Company continues to evaluate the other potential impacts that Topic 606 will have on its consolidated financial statements, internal controls, business processes, and information technology systems including, for example, how to account for commission expense and revenue models acquired from recent acquisitions. Business Combinations (Topic 805): Clarifying the Definition of a Business In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which provides a more robust framework to use in determining when a set of assets and activities is a business. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Financial Instruments In January 2016, the FASB issued ASU 2016-01, Financial Instruments, which impacts certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The standard will be effective for the Company beginning August 1, 2018. The Company is currently evaluating the effect the updated standard will have on its consolidated financial statements and related disclosures. Statement of Cash Flows (Topic 230): Restricted Cash In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires the statement of cash flows to report changes in cash, cash equivalents, and restricted cash. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Income Tax Consequences of an Intra-Entity Transfer of Assets Other Than Inventory In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”), which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new standard must be adopted using a modified retrospective transition method which is a cumulative-effective adjustment to retained earnings as of the beginning of the first effective reporting period. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Scope of Modification Accounting In May 2017, the FASB issued ASU No. 2017-09, Scope of Modification Accounting (Topic 718) (“ASU 2017-09”), which amends the scope of modification accounting for share-based payment arrangements. ASU 2017-09 provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The new standard is effective for annual periods beginning after December 15, 2017 and interim periods within those years. Early adoption is permitted. The standard will be

Fair Value of Financial Instruments	Financial Instruments and Fair Value Measurements The Company’s financial instruments consist of cash equivalent and investments classified as available-for-sale. The following table summarize the Company’s available-for-sale investments by significant investment categories as of July 31, 2017 and 2016 : July 31, 2017 Amortized Cost Unrealized Gains Unrealized Losses Estimated Fair Value (in thousands) U.S. agency securities $ 22,662 $ — $ (66 ) $ 22,596 Commercial paper 147,371 2 (34 ) 147,339 Corporate bonds 258,334 157 (146 ) 258,345 U.S. government bonds 67,164 — (185 ) 66,979 Certificate of deposit 27,498 29 — 27,527 Money market funds 96,313 — — 96,313 Total $ 619,342 $ 188 $ (431 ) $ 619,099 July 31, 2016 Amortized Cost Unrealized Gains Unrealized Losses Estimated Fair Value (in thousands) U.S. agency securities $ 58,070 $ 30 $ (12 ) $ 58,088 Commercial paper 152,317 12 (6 ) 152,323 Corporate bonds 274,656 321 (38 ) 274,939 U.S. government bonds 90,593 58 (2 ) 90,649 Foreign government bonds 2,418 9 — 2,427 Money market funds 114,833 — — 114,833 Total $ 692,887 $ 430 $ (58 ) $ 693,259 The following table presents the gross unrealized losses and fair value of the Company’s financial instruments with unrealized losses, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position: July 31, 2017 Less Than 12 Months 12 Months or Greater Total Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses (in thousands) U.S. agency securities $ 16,062 $ (41 ) $ 5,533 $ (25 ) $ 21,595 $ (66 ) Commercial paper 62,964 (34 ) — — 62,964 (34 ) Corporate bonds 139,764 (146 ) — — 139,764 (146 ) U.

As of July 31, 2017 , the Company had 113 investments in a gross unrealized loss position. The unrealized losses on its available-for-sale securities were primarily a result of unfavorable changes in interest rates subsequent to the initial purchase of these securities. The Company does not intend to sell, nor does it 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 July 31, 2017 to be other-than-temporarily impaired, nor are any unrealized losses considered to be credit losses. The Company has recorded the securities at fair value in its consolidated balance sheets, with unrealized gains and losses reported as a component of accumulated other comprehensive loss. The amount 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 material. The following table summarizes the contractual maturities of the Company’s financial instruments as of July 31, 2017 : Less Than 12 Months 12 to 24 Months Total (in thousands) U.S. agency securities $ 20,583 $ 2,013 $ 22,596 Commercial paper 147,339 — 147,339 Corporate bonds 170,654 87,691 258,345 U.S. government bonds 47,105 19,874 66,979 Certificate of deposit 22,520 5,007 27,527 Money market funds 96,313 — 96,313 Total $ 504,514 $ 114,585 $ 619,099 Fair Value Measurement The Company classifies cash equivalents, short-term investments and long-term investments within Level 1 or Level 2 in the fair value hierarchy because the Company uses quoted market prices or alternative pricing sources and models utilizing observable market inputs to determine their fair value. Fair value is defined as the exchange price that would be received for an asset or an exit price paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The Company uses a three-tier fair value hierarchy, which prioritizes the inputs used in the valuation methodologies in measuring fair value: Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2 - Inputs other than quoted prices included within Level I 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. The categorization of a financial instrument within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The carrying value of the Company’s accounts receivable, accounts payable and accrued liabilities approximates their fair value due to the short-term nature of these instruments. The Company bases the fair value of its Level 1 financial instruments, which are in active markets, using quoted market prices for identical instruments. The Company obtains the fair value of its Level 2 financial instruments, which are not in active markets, from a third-party professional pricing service using quoted market prices for identical or comparable instruments, rather than direct observations of quoted prices in active markets. The Company’s professional pricing service gathers observable inputs for all of its fixed income securities from a variety of industry data providers (e.g. large custodial institutions) and other third-party sources. Once the observable inputs are gathered, all data points are considered and an average price is determined. The Company validates the quoted market prices provided by its primary pricing service by comparing their assessment of the fair values of our Level 2 investment portfolio balance against the fair values of its Level 2 investment portfolio balance provided by its investment managers. The Company’s investment managers use similar techniques to its professional pricing service to derive pricing as described above. The Company did not have any Level 3 financial assets or liabilities as of July 31, 2017 , or 2016 . The following tables summarize the Company’s financial assets and liabilities measured at fair value on a recurring basis, by level within the fair value hierarchy: July 31, 2017 Level 1 Level 2 Level 3 Total (in thousands) Assets Cash equivalents: Commercial paper $ — $ 98,174 $ — $ 98,174 Money market funds 96,313 — — 96,313 Short-term investments: U.S. agency securities — 20,583 — 20,583 Commercial paper — 49,165 — 49,165 U.

Acquisition (Notes)	12 Months Ended

Business Combinations [Abstract]
Acquisition	Acquisitions The Company’s acquisitions during fiscal years 2017 and 2016 were all accounted for as business combinations. U.S. GAAP requires the Company to recognize separately from goodwill the assets acquired and the liabilities assumed at the acquisition date fair values. Goodwill as of the acquisition date is measured as the excess of consideration transferred over the net of the acquisition date fair value of the assets acquired and the liabilities assumed. The Company utilized the discounted cash flow methodology and the profit allocation methodology under the income approach to estimate the fair values of the intangible assets. The acquired intangible assets are amortized over their estimated useful lives. The Company used the cost build-up approach to estimate the fair value of deferred revenue by estimating the costs related to fulfilling the obligation plus an additional markup for an assumed operating margin to reflect the profit a third party would expect to make on the costs incurred. These fair value measurements were based on significant inputs that were not observable in the market and thus represents a Level 3 measurement. The valuation models were based on estimates of future operating projections of the acquired business and rights to sell new products containing the acquired technology as well as judgments on the discount rates used and other variables. The Company developed forecasts based on a number of factors including future revenue and operating cost projections, a discount rate that is representative of the weighted average cost of capital, in addition to royalty and long-term sustainable growth rates based on market analysis. Fiscal Year 2017 ISCS Acquisition On February 16, 2017, pursuant to the Agreement and Plan of Merger entered into on December 18, 2016, the Company completed its acquisition of ISCS, Inc., a privately-held company that provides a cloud-based, all-in-one system for policy administration, billing and claims management to P&C insurers (“ISCS Acquisition”). The gross purchase price of the ISCS Acquisition was $160 million , subject to certain preliminary adjustments including a net working capital adjustment, which resulted in cash consideration paid of $154.9 million . A portion of the consideration has been placed into an escrow account as partial security to satisfy any potential claims, including the indemnification liability for state sales taxes. The ISCS Acquisition is intended to enhance the Company's ability to serve those P&C insurers that prefer a cloud-based, all-in-one platform that offers policy, billing, and claims management functionality. Total acquisition costs of $1.1 million were expensed as incurred and recorded as general and administrative expenses in the accompanying consolidated statement of operations. In connection with the ISCS Acquisition, we recorded an indemnification asset of $1.6 million , which represents the selling security holders’ obligation under the Agreement and Plan of Merger to indemnify the Company for unpaid state sales taxes. The indemnification asset was recognized on the same basis as the corresponding liability, which is based on its estimated fair value as of the date of acquisition. The ISCS Acquisition was accounted for as a business combination. As part of the preliminary purchase price allocation, the Company determined that ISCS’s separately identifiable intangible assets were developed technology, customer contracts and related relationships, and order backlog. The valuation method used was in accordance with the Company’s policy, practice and experience as described above. Total Purchase Price Allocation Estimated Useful Lives (in thousands) (in years) Acquired assets, net of assumed liabilities $ 4,624 Developed technology 43,300 4 Customer contracts and related relationships 7,000 9 Order backlog 3,500 4 Deferred tax assets 171 Goodwill 96,337 Total preliminary purchase price $ 154,932 The goodwill of $96.3 million arising from the ISCS Acquisition consists largely of the acquired workforce, the expected company-specific synergies and the opportunity to expand the Company’s customer base. The goodwill recognized is expected to be deductible for income tax purposes. ISCS’s post-acquisition results of operations were included in the Company’s results of operations. Since the acquisition date, total revenue and net loss of ISCS for the period from February 16, 2017 through July 31, 2017 was $17.6 million and $4.8 million , respectively. Unaudited Pro Forma Financial Information The following unaudited pro forma financial information presents the consolidated results of the Company and ISCS for the fiscal year ended July 31, 2017 and 2016, after giving effect to the ISCS Acquisition as if it had occurred on August 1, 2015, and combines the historical financial results of the Company and ISCS. The unaudited pro forma financial information includes adjustments to give effect to pro forma events that are directly attributable to the ISCS Acquisition. The pro forma financial information includes adjustments for the amortization of intangible assets, adjustments to stock-based compensation expense, the effect of reduction of deferred revenue, and the inclusion of transaction costs on August 1, 2015 with a corresponding reduction of these amounts in the period originally recognized. The unaudited pro forma financial information is presented for illustrative purposes only and is not necessarily indicative of the results of operations that would have been realized had the ISCS Acquisition been completed on August 1, 2015, nor does it purport to project the results of operations of the combined company in future periods. The unaudited pro forma financial information does not give effect to any anticipated synergies and integration costs related to the acquired company. Consequently, actual results will differ from the unaudited pro forma financial information. Fiscal Year Ended July 31, 2017 2016 (Unaudited) (in thousands except for per share amounts) Pro forma revenues $ 539,202 $ 462,421 Pro forma net income (loss) $ 10,795 $ (5,470 ) Pro forma net income (loss) per share -- basic $ 0.15 $ (0.08 ) Pro forma net income (loss) per share -- diluted $ 0.15 $ (0.08 ) FirstBest Acquisition On August 31, 2016, the Company acquired all of the outstanding equity interests of FirstBest Systems, Inc. (the “FirstBest Acquisition”), a privately-held provider of underwriting management systems and related applications to P&C insurers. Total consideration for the FirstBest Acquisition was $37.8 million which included amounts placed into escrow to cover future potential claims. The Company believes that the FirstBest Acquisition will enable the expansion of its insurance platform by providing insurers in the U.S. and Canada writing complex commercial, specialty, and workers’ compensation lines greater support for their risk assessment and decision-making processes. Total acquisition costs of $1.2 million were expensed as incurred and recorded as general and administrative expenses in the accompanying consolidated statement of operations, of which, $0.9 million were expensed as incurred during the year ended July 31, 2017 and $0.3 million were expensed as incurred in the prior fiscal year. The FirstBest Acquisition was accounted for as a business combination. As part of the preliminary purchase price allocation, the Company determined that FirstBest’s separately identifiable intangible assets were developed technology, customer contracts and related relationships, and order backlog. The valuation method used was in accordance with the Company’s policy, practice and experience as described above. The allocation of the purchase price is preliminary pending the final valuation of intangible assets, certain acquired deferred tax assets and completion of certain statutory tax filing requirements and is therefore subject to potential future measurement period adjustments. The preliminary allocation of the purchase consideration was as follows: Total Purchase Price Allocation Estimated Useful Lives (in thousands) (in years) Acquired assets, net of assumed liabilities $ 2,518 Developed technology 8,000 5 Customer contracts and related relationships 6,500 9 Order backlog 900 3 Deferred tax assets, net 4,406 Goodwill 15,434 Total purchase price $ 37,758 The goodwill of $15.4 million arising from the acquisition consists largely of the acquired workforce, the expected company-specific synergies and the opportunity to expand the Company’s customer base. None of the goodwill recognized is expected to be deductible for income tax purposes. The results of FirstBest’s operations since the date of acquisition were included in the Company’s results of operations for the fiscal year ended July 31, 2017 , and were not material. The pro forma results of operations have not been presented because the effects of the business combination were not material to the Company’s consolidated results of operations. Fiscal Year 2016 EagleEye Acquisition On March 31, 2016, the Company purchased all of the outstanding equity interests of EagleEye Analytics, Inc. (“EagleEye”), a privately held provider of cloud-based predictive analytics products specifically designed for property and casualty insurers, for total purchase consideration of $40.2 million , including an amount placed into escrow to cover future potential claims. At the time of the purchase, EagleEye maintained a management incentive program that required certain payments to management upon the completion of a change in control. Pursuant to this program, an additional $1.6 million was placed into a separate escrow account to be paid out 18 months after closing to former EagleEye employees. This additional payment is subject to continued employment with the Company and therefore is excluded from the purchase consideration. The payment will be recognized as compensation expense over the requisite service period of 18 months. The Company believes that the acquisition will enable its customers to apply predictive analytics to make better decisions across the insurance lifecycle. Acquisition-related costs of $1.4 million were recorded in general and administrative expenses in the Company’s consolidated statements of operations for the fiscal year ended July 31, 2016. As part of the purchase price allocation, the Company determined that EagleEye’s separately identifiable intangible assets were developed technology, customer contracts and related relationships, partner relationships and order backlog. The Company measured fair values of the intangible assets by applying the income and relief from royalty approach. This fair value measurement is based on significant inputs that are not observable in the market and thus represents a Level 3 measurement. The valuation method used was in accordance with the Company’s policy, practice and experience as described above. The allocation of the purchase price is preliminary pending final valuation of acquired deferred tax assets and is therefore subject to potential future measurement period adjustments. Preliminary allocation of the purchase consideration was as follows: Total Purchase Price Allocation Estimated Useful Lives (in thousands) (in years) Assumed Liabilities, net of acquired assets $ (550 ) Developed technology 6,700 4 Customer contracts and related relationships 4,500 9 Partner relationships 200 9 Order backlog 1,100 3 Deferred tax assets, net 7,325 Goodwill 20,875 Total purchase price $ 40,150 The goodwill of $20.9 million arising from the acquisition consists largely of the acquired workforce, the expected company-specific synergies and the opportunity to expand the Company’s customer base. None of the goodwill recognized is expected to be deductible for income tax purposes. The results of EagleEye’s operations since the date of acquisition have been included in the Company’s results for the fiscal year ended July 31, 2016 and were not material.

Balance Sheet Components	Balance Sheet Components Property and Equipment, net Property and equipment, net consisted of the following: July 31, 2017 July 31, 2016 (in thousands) Computer hardware $ 21,408 $ 19,257 Purchased software 3,855 5,066 Capitalized software development costs 1,065 — Furniture and fixtures 3,253 3,492 Leasehold improvements 8,251 8,434 Total property and equipment 37,832 36,249 Less accumulated depreciation (23,456 ) (23,294 ) Property and equipment, net $ 14,376 $ 12,955 As of July 31, 2017 and 2016 , no property and equipment was pledged as collateral against borrowings. Amortization of leasehold improvements is included in depreciation expense. Depreciation expense was $6.6 million , $6.5 million and $6.0 million for the years ended July 31, 2017 , 2016 and 2015 , respectively. During the third quarter of 2017, the Company began to capitalize software development costs for a cloud-based technology application that the Company will offer solely for its software subscription service. The amount capitalized was $ 1.1 million for the fiscal year ended July 31, 2017 and comprised primarily of compensation and related headcount costs for employees who were directly associated with the software development projects. Other Assets The Company’s other assets of $20.1 million and $12.3 million at July 31, 2017 and 2016, respectively, include the strategic equity investment in a privately-held company, which was accounted for using the cost method of accounting. Strategic investments are non-marketable equity securities, in which the Company does not have a controlling interest or the ability to exert significant influence. These investments do not have a readily determinable market value. Under the cost method of accounting, the non-marketable securities are carried at cost and are adjusted only for other-than temporary impairments, certain distributions and additional investments. Accordingly, if the Company were to disclose the fair value of the investment, the fair value measurement would be Level 3 in the valuation hierarchy. The Company assesses the investment for impairment when events or changes in circumstances indicate that its carrying amount may not be recoverable. In December 2015, the Company invested $5.0 million in a convertible note issued by a privately-held company. In April 2016, the convertible note with accrued interest was converted to preferred stock. The investment was re-measured at $6.0 million based on the estimated fair value of the preferred stock at the date of conversion. This equity investment was reported in long-term other assets on the Company’s consolidated balance sheet as of July 31, 2016. During the third quarter of 2017, the Company invested an additional $4.7 million in this privately-held company resulting in no significant change in ownership or degree of influence. As of July 31, 2017 and July 31, 2016 , there were no indicators that the investment with carrying values of $10.7 million and $6.0 million , respectively, were impaired.

Earnings Per Share [Abstract]
Net Income per Share	Net Income per Share The Company calculates basic earnings per share by dividing the net income by the weighted average number of shares of common stock outstanding for the period. The diluted earnings per share is computed by giving effect to all potential dilutive common stock equivalents outstanding for the period. For purposes of this calculation, options to purchase common stock and restricted stock units are considered to be common stock equivalents. The following table sets forth the computation of the Company’s basic and diluted net income per share for the years ended July 31, 2017 , 2016 and 2015 : Fiscal years ended July 31, 2017 2016 2015 (in thousands, except share and per share amounts) Numerator: Net income $ 21,224 $ 14,976 $ 9,885 Denominator: Basic - weighted-average shares 73,994,577 72,026,694 70,075,908 Weighted-average effect of dilutive securities: Stock options 544,520 859,855 1,223,106 Restricted stock units 789,246 879,411 1,015,419 Diluted - weighted-average shares 75,328,343 73,765,960 72,314,433 Net income per share: Basic $ 0.29 $ 0.21 $ 0.14 Diluted $ 0.28 $ 0.20 $ 0.14 The following outstanding shares of common stock equivalents are excluded from the computation of diluted net income per share for the periods presented because including them would have been antidilutive: Fiscal years ended July 31, 2017 2016 2015 Stock options to purchase common stock 24,128 77,737 290,670 Restricted stock units 88,582 22,994 678

(2) Royalty obligations primarily represent our obligations under our non-cancellable agreements related to software used in certain revenue-generating agreements. (3) Purchase commitments consist of agreements to purchase services, entered into in the ordinary course of business. These represent non-cancellable long term commitments for which a penalty would be imposed if the agreement was canceled for any reason other than an event of default as described by the agreement. 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 new corporate headquarters, located in Foster City, California, for approximately 97,674 square feet of space commencing August 1, 2012. In connection with the 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 from $0.8 million 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 $6.8 million , $5.7 million and $5.5 million during the years ended July 31, 2017 , 2016 and 2015 , respectively. Letters of Credit 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 as of July 31, 2016 to secure contractual commitments and prepayments. In May 2017, this letter of credit was closed and no longer outstanding. Legal Proceedings From time to time, the Company is involved in various other legal proceedings and receives claims, arising from the normal course of business activities. The Company has not accrued for estimated losses in the accompanying consolidated financial statements as the Company has determined that no provision for liability nor disclosure is required related to any claim against the Company because: (a) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial. 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 are outstanding as of July 31, 2017 and 2016 . 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.

Stockholders' Equity and Stock-based Compensation [Abstract]
Stockholders' Equity and Stock-based Compensation	Stockholders’ Equity and Stock-Based Compensation Equity Incentive Plans On September 14, 2011, the Company’s Board of Directors adopted the 2011 Stock Plan (“2011 Plan”) for the purpose of granting equity-based incentive awards as compensation tools to motivate the Company’s workforce. The Company had initially reserved 7,500,000 shares of its common stock for the issuance of awards under the 2011 Plan. The 2011 Plan provides that the number of shares reserved and available for issuance under the plan will automatically increase each January 1, beginning on January 1, 2013, by up to 5% of the outstanding number of shares of the Company’s common stock on the immediately preceding December 31. This number is subject to adjustment in the event of a stock split, stock dividend or other defined changes in the Company’s capitalization. In addition, the Company has equity awards outstanding from its other equity incentive plans, the 2006 Stock Plan, the 2009 Stock Plan and the 2010 Restricted Stock Unit Plan, which were discontinued for the purposes of making new grants upon the adoption of the 2011 Plan. In fiscal year 2015, the Company began requiring that employees sell a portion of the shares that they receive upon the vesting of RSUs in order to cover any required withholding taxes (“sell-to-cover”), rather than its previous approach of net share settlement. Stock-Based Compensation Expense Stock-based compensation cost related to options and restricted stock units (“RSUs”) granted to employee and non-employee is as follows: Fiscal years ended July 31, 2017 2016 2015 (in thousands) Total cost of stock-based compensation $ 72,695 $ 66,409 $ 51,375 Impact of capitalized stock-based compensation (901 ) (278 ) — Amount charged to income $ 71,794 $ 66,131 $ 51,375 Stock-based compensation cost charged to the following expense categories: Cost of license and other revenues $ 373 $ 433 $ 222 Cost of maintenance revenues 1,694 1,491 1,158 Cost of services revenues 18,622 17,878 15,022 Research and development 18,123 15,555 10,683 Sales and marketing 16,663 15,090 12,090 General and administrative 16,319 15,684 12,200 Total stock-based compensation expense 71,794 66,131 51,375 Tax benefit from stock-based compensation 23,014 20,092 19,087 Total stock-based compensation expense, net of tax effect $ 48,780 $ 46,039 $ 32,288 As of July 31, 2017 , total unrecognized compensation cost, adjusted for estimated forfeitures and before tax benefit, was as follows: As of July 31, 2017 Unrecognized Expense Weighted Average Expected Recognition Period (in thousands) (in years) Restricted stock units $ 118,288 2.4 Stock options 990 1.1 $ 119,278 RSUs RSU activity under the Company’s equity incentive plans is as follows: Number of RSUs Weighted Average Grant Date Fair Value Aggregate Intrinsic Value (1) (in thousands) Balance as of July 31, 2014 3,384,221 $ 30.70 $ 137,061 Granted 1,664,413 47.50 Released (1,819,825 ) 25.99 $ 88,648 Canceled (346,135 ) 36.72 Balance as of July 31, 2015 2,882,674 42.65 $ 170,222 Granted 1,586,192 54.99 Released (1,408,746 ) 41.21 $ 78,763 Canceled (332,396 ) 46.71 Balance as of July 31, 2016 2,727,724 50.08 $ 167,673 Granted 1,542,235 61.22 Released (1,372,770 ) 49.38 $ 81,427 Canceled (263,104 ) 53.53 Balance as of July 31, 2017 2,634,085 $ 56.62 $ 190,076 Expected to vest as of July 31, 2017 2,465,394 $ 56.40 $ 177,903 (1) Aggregate intrinsic value at each fiscal year end represents the total market value of RSUs at the Company’s closing stock price of $72.16 , $61.47 and $59.05 on July 31, 2017 , 2016 and 2015 , respectively. Aggregate intrinsic value for released RSUs represents the total market value of released RSUs at date of release. The Company’s restricted stock units also included PSU and TSR PSU awards, which have been granted to certain executives and employees of the Company. The PSU awards included performance conditions as well as time-based vesting which generally vest over four -year period. The TSR PSUs are subject to total shareholder return rankings relative to the software companies in the S&P Software and Services Select Industry Index for a specified performance period or specified performance periods, and vest at the end of three years. In select cases, certain TSR PSUs are also subject to performance-based conditions. The number of TSR PSUs that may ultimately vest will vary based on the relative performance of the Company’s total shareholder return rankings relative to the software companies in the S&P Software and Services Select Industry Index for a specified performance period or specified performance periods. The Monte Carlo methodology incorporates into the valuation all possible outcomes, including that the Company’s relative performance may result in no shares vesting. As a result, stock-based compensation expense is recognized regardless of the ultimate achievement of the plan’s performance metrics. The expense will be reversed only in the event that a grantee is terminated prior to satisfying the requisite service period. For a subset of TSR PSUs, the number of shares that may ultimately vest will vary based on the achievement of certain Company specific financial performance metrics in addition to the Company’s total shareholder return condition noted above. As a result, the expense recognized will fluctuate based on the Company’s estimated financial performance relative to the target financial performance metrics. The Company recognized stock-based compensation of $9.4 million , $6.9 million and $2.4 million that were related to these performance-based awards in fiscal years 2017 , 2016 and 2015 , respectively. Valuation assumptions of TSR PSUs The fair values of the TSR PSUs were estimated at the grant date using Monte Carlo simulation model which included the following assumptions: Fiscal years ended July 31, 2017 2016 2015 Expected term (in years) 2.66 - 2.88 * * Risk-free interest rate 0.89% - 1.34% * * Expected volatility 30.2% - 31.5% * * Average expected volatility of the peer companies in the index 36.9% - 37.0% * * Expected dividend yield —% * * * There were no TSR PSUs granted during fiscal years ended July 31, 2016 and 2015.

Aggregate intrinsic value for exercised options represents the difference between the Company’s stock price at date of exercise and the exercise price. Valuation assumptions of Stock Options The per share fair value of each stock option was determined using the Black-Scholes option-pricing model with the following assumptions: Fiscal years ended July 31, 2017 2016 2015 Expected life (in years) * 4.9 6.0 - 6.1 Risk-free interest rate * 1.5% 1.7% - 1.9% Expected volatility * 38.8% 39.4% - 45.1% Expected dividend yield * —% —% Weighted average fair value of options granted * $19.18 $20.78 * There were no options granted during fiscal year ended July 31, 2017.

As a result, the pre-tax excess tax benefits included in federal and California net operating loss carryforwards on the tax returns but not reflected in deferred tax assets for fiscal year 2017 are $176.1 million and $50.6 million , respectively. Federal and California laws impose restrictions on the utilization of net operating loss carryforwards and R&D credit carryforwards in the event of a change in ownership of the Company, which constitutes an “ownership change” as defined by Internal Revenue Code Sections 382 and 383. The Company experienced an ownership change in the past that does not materially impact the availability of its net operating losses and tax credits. Nevertheless, should there be an ownership change in the future, the Company’s ability to utilize existing carryforwards could be substantially restricted. 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 July 31, 2017 , U.S. income taxes were not provided for on the cumulative total of $35.6 million in undistributed earnings from profitable foreign subsidiaries. As of July 31, 2017 , the unrecognized deferred tax liability for these earnings was approximately $10.8 million . Unrecognized Tax Benefits The following table summarizes the activity related to unrecognized tax benefits: Fiscal years ended July 31, 2017 2016 2015 (in thousands) Unrecognized tax benefit - beginning of period $ 7,687 $ 6,109 $ 7,976 Gross increases - prior period tax positions 712 177 1 Gross decreases - prior period tax positions (691 ) (216 ) (2,896 ) Gross increases - current period tax positions 1,638 1,617 1,028 Unrecognized tax benefit - end of period $ 9,346 $ 7,687 $ 6,109 During the year ended July 31, 2017 , the Company’s unrecognized tax benefits increased by $1.7 million , primarily associated with the Company’s U.S. federal and California R&D tax credits. As of July 31, 2017 , the Company had unrecognized tax benefits of $4.0 million that, if recognized, would affect the Company’s effective tax rate. The Company or one of its subsidiaries files income taxes in the U.S. federal jurisdiction and various states and foreign jurisdictions. If the Company utilizes net operating losses or tax credits in future years, the U.S. federal, state and local, and non-U.S. tax authorities may examine the tax returns covering the period in which the net operating losses and tax credits arose. As a result, the Company’s tax returns in the U.S. and California remain open to examination from fiscal years 2002 through 2017 . As of July 31, 2017 , the Company has no tax audits in progress in the U.S. and in foreign jurisdictions.

Segment Reporting [Abstract]
Segment Information	Segment Information The Company operates in one segment. The Company’s chief operating decision maker (the “CODM”), its Chief Executive Officer, manages the Company’s operations on a consolidated basis for purposes of allocating resources. When evaluating the Company’s financial performance, the CODM reviews separate revenue information for the Company’s license, maintenance and professional services offerings, while all other financial information is reviewed on a consolidated basis. All of the Company’s principal operations and decision-making functions are located in the United States. The following table sets forth revenues by country and region based on the billing address of the customer: Fiscal years ended July 31, 2017 2016 2015 (in thousands) United States $ 301,155 $ 230,935 $ 208,104 Canada 50,981 44,717 37,833 Other Americas 19,447 18,114 7,162 Total Americas 371,583 293,766 253,099 United Kingdom 32,554 34,031 44,393 Other EMEA 48,727 41,914 47,449 Total EMEA 81,281 75,945 91,842 Total APAC 61,420 54,735 35,596 Total revenues $ 514,284 $ 424,446 $ 380,537 No country other than those listed above accounted for more than 10% of revenues during the years ended July 31, 2017 , 2016 and 2015 .

The Company and Summary of Si19

The Company and Summary of Significant Accounting Policies and Estimates (Policies)	12 Months Ended
	Jul. 31, 2017	Jul. 31, 2015
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business	Company 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. The Company’s technology platform supports core insurance operations, including underwriting, 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 are primarily insurance carriers for property and casualty insurance.
Basis of Presentation	Basis of Presentation and Consolidation Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). The consolidated financial statements include the accounts of Guidewire Software, Inc. and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the accompanying 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 from these estimates.
Foreign Currency Translation	Foreign Currency The functional currency of the Company’s foreign subsidiaries is their respective local currency. The Company translates all assets and liabilities of foreign subsidiaries to U.S. dollars at the current exchange rate as of the applicable balance sheet date. Revenues and expenses are translated at the average exchange rate prevailing during the period in which the transactions occur. The effects of foreign currency translations are recorded in accumulated other comprehensive income/loss as a separate component of stockholders’ equity in the accompanying consolidated statements of stockholders’ equity. Transaction gains and losses from foreign currency transactions that arise from exchange rate fluctuations on transactions denominated in a currency other than the local functional currency are recorded as other income (expense) in the consolidated statements of operations.
Cash, Cash Equivalents, Investments and Restricted cash	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 primarily 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 classified as available-for-sale. 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) income.
Property and Equipment	Property and Equipment Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is calculated on a straight-line basis over the estimated useful lives of the assets. Leasehold improvements are amortized over the shorter of the lease term or the estimated useful lives of the related assets. Maintenance and repairs that do not extend the life or improve an asset are expensed in the period incurred. The estimated useful lives of property and equipment are as follows: Computer hardware 3 years Purchased software 3 years Furniture and fixtures 3 years Leasehold improvements Shorter of the lease term or estimated useful life
Software Development Costs	Certain software development costs incurred subsequent to the establishment of technological feasibility are subject to capitalization and amortized over the estimated lives of the related products. Technological feasibility is established upon completion of a working model. Through July 31, 2017, costs incurred subsequent to the establishment of technological feasibility have not been material, and therefore, all software development costs have been charged to research and development expense in the accompanying consolidated statements of operations as incurred. For qualifying costs incurred for computer software developed for internal use, the Company begins to capitalize its costs to develop software when preliminary development efforts are successfully completed, management has authorized and committed project funding, and it is probable that the project will be completed and the software will be used as intended. These capitalized costs are amortized to expense over the estimated useful life of the related asset, generally estimated to be three years. Costs incurred prior to meeting these capitalization criteria and costs incurred for training and maintenance are expensed as incurred and recorded in research and development expense on the Company’s consolidated statements of operations. Capitalized software development costs are recorded in property and equipment on the Company’s consolidated balance sheet as of July 31, 2017.
Business Combinations	The Company uses its best estimates and assumptions to assign fair value to the tangible and intangible assets acquired and liabilities assumed at the acquisition date. Goodwill is calculated as the difference between the acquisition-date fair value of the consideration transferred and the values assigned to the assets acquired and liabilities assumed. The Company’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and subject to refinement and, as a result, actual results may differ from estimates. During the measurement period, which may be up to one year from the acquisition date, if new information is obtained about facts and circumstances that existed as of the acquisition date, the Company may record adjustments to the fair value of these assets and liabilities, with the corresponding offset to goodwill. During the year ended July 31, 2016, the Company adopted ASU 2015-16, “Simplifying the Accounting for Measurement-Period Adjustments (Topic 805)” (“ASU 2015-16”), which requires the cumulative impact of measurement period adjustments (including the impact on prior periods) to be recognized in the reporting period in which the adjustments are identified. Upon the conclusion of the measurement period or final determination of the fair value of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are recorded to the Company’s consolidated statements of operations.	0
Impairment of Long-Lived Assets, Intangible Assets and Goodwill
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”). No customer individually accounted for 10% or more of the Company’s revenues for the years ended July 31, 2017 , 2016 and 2015 . As of July 31, 2017 , one customer accounted for 11% of the Company’s total accounts receivable. As of July 31, 2016, No customer individually accounted for 10% or more of the Company’s total accounts receivable.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at invoiced amounts, net of the Company’s estimated allowances for doubtful accounts. The allowance for doubtful accounts is estimated based on an assessment of the Company’s ability to collect on customer accounts receivable, and there is judgment involved in such assessment. The Company regularly reviews the allowance by considering relevant factors such as historical experience, industry data, credit quality, age of accounts receivable balances, customers’ financial condition and current economic conditions that may affect a customer’s ability to pay. The Company has had no allowance for doubtful accounts in any of the periods presented. The Company’s accounts receivable are not collateralized by any security.
Revenue Recognition	Revenue Recognition The Company enters into arrangements to deliver multiple products or services (multiple-elements). For a substantial majority of its sales, the Company applies software revenue recognition rules and allocates the total revenues among elements based on vendor-specific objective evidence (“VSOE”) of the 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 software subscription models including those from recently acquired companies; (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 from professional services related to implementation of the Company’s 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. 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. Generally, the Company offers extended payment terms to its customers for term licenses. As a result, term license fees are not considered to be fixed and determinable until they become due or payment is received. • 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. Substantially all of the Company’s professional services engagements are billed on a time and materials basis. Services are typically not considered to be essential to the functionality of the software and the related revenues and costs are recognized in the period incurred. In select situations, the Company will contract its professional services on a fixed fee basis. In these situations, if reliable estimates of total project costs are available, the Company recognizes services revenues on a proportional performance basis as the 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. If reliable estimates of total project costs cannot be made, the zero gross margin or the completed contract method is applied to revenues and direct costs. Under the zero gross margin method, revenues recognized are limited to the direct costs incurred for the implementation services. Under the completed contract method, revenues and direct costs are deferred until the project is complete. When the zero gross margin method is applied for lack of reliable project estimates and subsequently project estimates become reliable, the Company switches to the percentage-of-completion method, resulting in a cumulative effect adjustment for deferred license revenues to the extent of progress toward completion, and the related portion of the deferred professional service margin is recognized in full as revenues. In the limited 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. The Company sells some of its software licenses on a subscription basis and the related revenues are recognized ratably over the term of the arrangement typically upon provisioning the products.
Deferred Revenues	As noted above, the Company generally invoices fees for licenses and maintenance to its customers in annual or quarterly installments payable in advance. Deferred revenues represent amounts, which are billed to or collected from creditworthy 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.
Sales Commissions	Sales Commissions Sales commissions are recognized as an expense when earned by the sales representative, generally occurring at the time the customer order is signed. Substantially all of the effort by the sales force is expended through the time of closing the sale, with limited to no involvement thereafter.
Warranties	Warranties The Company generally provides a warranty for its software products and services to its customers for periods ranging from 3 to 12 months . The Company’s software products are generally warranted to be free of defects in materials and workmanship under normal use and to substantially perform as described in published documentation. The Company’s services are generally warranted to be performed in a professional manner and to materially conform to the specifications set forth in the related customer contract. In the event there is a failure of such warranties, the Company generally will correct the problem or provide a reasonable workaround or replacement product. If the Company cannot correct the problem or provide a workaround or replacement product, then the customer’s remedy is generally limited to refund of the fees paid for the nonconforming product or services. Warranty expense has been insignificant to date.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred and amounts incurred were not material during the years ended July 31, 2017 , 2016 and 2015 .
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation using the fair value method, which requires the Company to measure the stock-based compensation based on the grant-date fair value of the awards and recognize the compensation expense over the requisite service period. The Company recognizes compensation expense net of estimated forfeitures. To date, the Company has granted stock options, time-based restricted stock units (“RSUs”), performance-based restricted stock units (“PSUs”), and beginning in the first quarter of fiscal 2017, restricted stock units that may be earned subject to the Company’s total shareholder return ranking relative to the software companies in the S&P Software and Services Select Industry Index for a specified performance period or specified performance periods, service periods, and in select cases, subject to certain performance conditions (“TSR PSUs”). The Company recognizes compensation expense 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 that contain either a performance condition, market conditions, or both using the graded vesting method. The fair value of the Company’s RSUs and PSUs equals the market value of the Company’s common stock on the date of grant. The Company estimates the grant date fair value of the Company’s stock options using the Black-Scholes option-pricing model. These awards are subject to time-based vesting, which generally occurs over a period of four years. The fair value of the Company’s TSR PSUs are estimated at the grant date using a Monte Carlo simulation method. The assumptions utilized in this simulation require judgments and estimates. Changes in these inputs and assumptions could affect the measurement of the estimated fair value of the related compensation expense. Compensation expense associated with these TSR PSUs will be recognized over the vesting period regardless of whether the market condition is ultimately satisfied, however, the expense will be reversed if a grantee terminates prior to satisfying the requisite service period. For TSR PSUs containing an additional performance condition, a portion of the expense will fluctuate depending on the achievement of the performance conditions. All TSR PSUs will vest at the end of a three-year period.
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. All deferred tax assets and liabilities are classified as non-current on its consolidated financial statements. 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. 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 tax audits, changes 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 consolidated statement of operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Improvements on Employee Share-Based Payment Accounting In March 2016, the FASB issued Accounting Standards Update No. 2016-09, Improvements on Employee Share-Based Payment Accounting (Topic 718) (“ASU 2016-09”), which simplifies several aspects of the accounting for employee share-based payment transactions for both public and nonpublic entities, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance requires all of the tax effects related to share based payments to be recorded through the income statement. The guidance also removes the present requirement to delay recognition of a windfall tax benefit until it reduces current taxes payable; instead it is recognized at the time of settlement, subject to normal valuation allowance consideration. The standard is effective for public business entities for annual reporting periods beginning after December 15, 2016, and interim periods within that reporting period. Early adoption is permitted. The Company will adopt this standard effective on August 1, 2017. Upon adoption of this guidance the Company will change its accounting policy to account for forfeitures for share based awards as they occur and will record a cumulative effect adjustment to opening retained earnings. The amendments related to accounting for previously unrecognized excess tax benefits as deferred tax assets will be adopted on a modified retrospective basis with a cumulative effect adjustment to opening retained earnings, subject to valuation allowance considerations that we are still evaluating. Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), 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. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date (“ASU 2015-14”), deferring the effective date of this standard. As a result, the ASU and related amendments will be effective for the Company for its fiscal year beginning August 1, 2018, including interim periods within that fiscal year. Early adoption is permitted, but not before the original effective date of the ASU, August 1, 2017. Subsequently, the FASB issued ASU No. 2016-08, Principal Versus Agent Consideration (or Reporting Revenue Gross versus Net) (“ASU 2016-08”) in March 2016, ASU No. 2016-10, Identifying Performance Obligations and Licensing in April 2016, and ASU No. 2016-12, Narrow-Scope Improvements and Practical Expedients in May 2016. These amendments clarified certain aspects of Topic 606 and have the same effective date as ASU 2014-09. The Company will adopt these ASUs (collectively, Topic 606) on August 1, 2018. Topic 606 permits two methods of adoption: retrospectively to each prior reporting period presented (the “Full Retrospective Method”), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the “Modified Retrospective Method”). The Company currently intends to apply the Modified Retrospective Method. The Company has evaluated the potential impact of Topic 606 on its revenue recognition policy and practices and has concluded that Topic 606 will impact the pattern of its revenue recognition associated with its software licenses. The Company’s term licenses require payments to be made annually or quarterly in advance and are subject to extended payment terms. Currently, revenues associated with the payment for term software licenses are recognized in the earlier of the period in which the payments are due or are actually made. Under Topic 606, the Company will be required to recognize the revenue associated with such payments not when they are made or due, but when control of the software license is transferred to the customer, which occurs at or near the time a contract with a customer is executed. As a result, under Topic 606, all contractually obligated payments under a term license that the Company reasonably expects to collect would be recognized upon delivery. In conjunction with its evaluation of this new standard, the Company began revising its contracting practices and amending existing agreements with certain customers primarily by shortening the initial, non-refundable term of its licenses. Since fiscal 2016, a substantial majority of new contracts feature a two-year initial term with subsequent one-year auto renewal options. The Company has engaged with its existing and prospective customers on its new licensing model. The Company continues to evaluate the other potential impacts that Topic 606 will have on its consolidated financial statements, internal controls, business processes, and information technology systems including, for example, how to account for commission expense and revenue models acquired from recent acquisitions. Business Combinations (Topic 805): Clarifying the Definition of a Business In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which provides a more robust framework to use in determining when a set of assets and activities is a business. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Financial Instruments In January 2016, the FASB issued ASU 2016-01, Financial Instruments, which impacts certain aspects of recognition, measurement, presentation and disclosure of financial instruments. The standard will be effective for the Company beginning August 1, 2018. The Company is currently evaluating the effect the updated standard will have on its consolidated financial statements and related disclosures. Statement of Cash Flows (Topic 230): Restricted Cash In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires the statement of cash flows to report changes in cash, cash equivalents, and restricted cash. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which clarifies how companies present and classify certain cash receipts and cash payments in the statement of cash flows. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Income Tax Consequences of an Intra-Entity Transfer of Assets Other Than Inventory In October 2016, the FASB issued ASU No. 2016-16, Income Taxes - Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”), which requires entities to recognize the income tax consequences of an intra-entity transfer of an asset other than inventory when the transfer occurs. The new standard must be adopted using a modified retrospective transition method which is a cumulative-effective adjustment to retained earnings as of the beginning of the first effective reporting period. The standard will be effective for the Company beginning August 1, 2018. Based on its current assessment, the Company does not expect the adoption of this update to have a material impact on its consolidated financial statements. Scope of Modification Accounting In May 2017, the FASB issued ASU No. 2017-09, Scope of Modification Accounting (Topic 718) (“ASU 2017-09”), which amends the scope of modification accounting for share-based payment arrangements. ASU 2017-09 provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The new standard is effective for annual periods beginning after December 15, 2017 and interim periods within those years. Early adoption is permitted. The standard will be effective for the Company beginning August 1, 2018. The Company is currently evaluating the impact this update will have on its consolidated financial statements. Accounting for Leases In February 2016, the FASB issued Accounting Standards Update No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”), which requires lessees to put most leases on their balance sheets but recognize the expenses on their income statements in a manner similar to current practice. ASU 2016-02 states that a lessee would recognize a lease liability for the obligation to make lease payments and a right-to-use asset for the right to use the underlying asset for the lease term. The standard will be effective for the Company beginning August 1, 2019. The Company is currently evaluating the impact this update will have on its consolidated financial statements. Simplifying the Test for Goodwill Impairment In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which removes the requirement for an entity to calculate the implied fair value of goodwill (as part of step 2 of the current goodwill impairment test) in measuring a goodwill impairment loss.
