Nature of Business

Accounting Policies [Abstract]
Nature of Business	Nature of Business Fair Isaac Corporation Incorporated under the laws of the State of Delaware, Fair Isaac Corporation (“FICO”) is a provider of analytic, software and data management products and services that enable businesses to automate, improve and connect decisions. FICO provides a range of analytical solutions, credit scoring and credit account management products and services to banks, credit reporting agencies, credit card processing agencies, insurers, retailers, telecommunications providers, pharmaceutical companies, healthcare organizations, public agencies and organizations in other industries. In these condensed consolidated financial statements, Fair Isaac Corporation is referred to as “FICO,” “we,” “us,” “our,” or “the Company.” Principles of Consolidation and Basis of Presentation We have prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q and the applicable accounting guidance. Consequently, we have not necessarily included all information and footnotes required for audited financial statements. In our opinion, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our financial position and results of operations. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with our audited consolidated financial statements and notes thereto presented in our Annual Report on Form 10-K for the year ended September 30, 2017 . The interim financial information contained in this report is not necessarily indicative of the results to be expected for any other interim period or for the entire fiscal year. The condensed consolidated financial statements include the accounts of FICO and its subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates We make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures made in the accompanying notes. For example, we use estimates in determining the collectability of accounts receivable; the appropriate levels of various accruals; labor hours in connection with fixed-fee service contracts; the amount of our tax provision and the realizability of deferred tax assets. We also use estimates in determining the remaining economic lives and carrying values of acquired intangible assets, property and equipment, and other long-lived assets. In addition, we use assumptions to estimate the fair value of reporting units and share-based compensation. Actual results may differ from our estimates. New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “ Revenue from Contracts with Customers (Topic 606) ” (“ASU 2014-09”). ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. Generally Accepted Accounting Principles when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In August 2015, the FASB issued ASU No 2015-14, “ Deferral of the Effective Date ” (“ASU 2015-14”), which defers the effective date for ASU 2014-09 by one year. For public entities, the guidance in ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods), which means it will be effective for our fiscal year beginning October 1, 2018. Early adoption is permitted to the original effective date of December 15, 2016 (including interim reporting periods within those periods). In March 2016, the FASB issued ASU No. 2016-08, “ Principal versus Agent Considerations (Reporting Revenue versus Net) ” (“ASU 2016-08”), which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard. In April 2016, the FASB issued ASU No. 2016-10, “ Identifying Performance Obligations and Licensing ” (“ASU 2016-10”), which reduces the complexity when applying the guidance for identifying performance obligations and improves the operability and understandability of the license implementation guidance. In May 2016, the FASB issued ASU No. 2016-12 “ Narrow-Scope Improvements and Practical Expedients ” (“ASU 2016-12”), which amends the guidance on transition, collectability, noncash consideration and the presentation of sales and other similar taxes. In December 2016, the FASB further issued ASU 2016-20, “ Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ” (“ASU 2016-20”), which makes minor corrections or minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments are intended to address implementation issues that were raised by stakeholders and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. These amendments have the same effective date as the new revenue standard. We have established a cross-functional implementation team consisting of representatives across the organization to address the scope of work required to implement the recognition and disclosure requirements under the new standard. This cross-functional implementation team has developed a project plan, which includes evaluating customer contracts across the organization, developing policies, processes and tools to report financial results, and implementing and evaluating our internal controls over financial reporting that will be necessary under the new standard. We currently plan to adopt Topic 606 in the first quarter of our fiscal 2019 using the retrospective transition method. Our ability to adopt Topic 606 using the full retrospective method is dependent on system readiness, and the completion of our analysis of information necessary to restate prior period financial statements. As we continue to assess the new standard along with industry trends and additional interpretive guidance, we may adjust our implementation plan accordingly. We are continuing to assess the impact of adopting Topic 606 on our consolidated financial statements and believe the new standard will impact the following policies and disclosures: • Timing of revenue recognition of license revenue on term licenses and transactional revenue on guaranteed minimum fees related to our on-premises software products. Under the new standard, we expect to recognize revenue when control of the license is transferred to the customer, rather than at the date payments become due and payable or ratably over the term of the contract required under the current standard; • Presentation of contract balances. Under the new standard, when we enter into noncancellable contracts that provide unconditional rights to payment from our customers for services that we have not yet completed providing or services we will provide in the near future, we expect to present the unconditional rights as receivables, regardless of whether cash has been received from customers; • Required disclosures including information about remaining transaction price and when we expect to recognize revenue; and • Accounting for commissions under the new standard will result in the deferral of incremental commission costs for obtaining contracts. We do not currently expect Topic 606 to have a significant effect on the timing of revenue recognition for our maintenance or professional services revenues, or SaaS contracts. In October 2016, the FASB issued ASU No. 2016-16, “ Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory ” (“ASU 2016-16”). ASU 2016-16 requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The guidance is effective for fiscal years and interim periods beginning after December 15, 2017, which means it will be effective for our fiscal year beginning October 1, 2018. ASU 2016-16 should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the beginning of the period of adoption. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued. We do not believe that adoption of ASU 2016-16 will have a significant impact on our consolidated financial statements. In February 2016, the FASB issued ASU 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. ASU 2016-02 is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018, which means it will be effective for our fiscal year beginning October 1, 2019. Early adoption is permitted. We are currently evaluating the timing of our adoption and the impact that the updated standard will have on our consolidated financial statements.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. The accounting guidance establishes a three-level hierarchy for disclosure that is based on the extent and level of judgment used to estimate the fair value of assets and liabilities. • Level 1 - uses unadjusted quoted prices that are available in active markets for identical assets or liabilities. Our Level 1 assets are comprised of money market funds and certain equity securities. • Level 2 - uses inputs other than quoted prices included in Level 1 that are either directly or indirectly observable through correlation with market data. These include quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; and inputs to valuation models or other pricing methodologies that do not require significant judgment because the inputs used in the model, such as interest rates and volatility, can be corroborated by readily observable market data. We do not have any assets that are valued using inputs identified under a Level 2 hierarchy as of March 31, 2018 and September 30, 2017 . • Level 3 - uses one or more significant inputs that are unobservable and supported by little or no market activity, and that reflect the use of significant management judgment. Level 3 assets and liabilities include those whose fair value measurements are determined using pricing models, discounted cash flow methodologies or similar valuation techniques, and significant management judgment or estimation. We do not have any assets or liabilities that are valued using inputs identified under a Level 3 hierarchy as of March 31, 2018 and September 30, 2017 . The following tables represent financial assets that we measured at fair value on a recurring basis at March 31, 2018 and September 30, 2017 : March 31, 2018 Active Markets for Identical Instruments (Level 1) Fair Value as of March 31, 2018 (In thousands) Assets: Cash equivalents (1) $ 11,237 $ 11,237 Marketable securities (2) 16,134 16,134 Total $ 27,371 $ 27,371 September 30, 2017 Active Markets for Fair Value as of September 30, 2017 (In thousands) Assets: Cash equivalents (1) $ 15,295 $ 15,295 Marketable securities (2) 13,791 13,791 Total $ 29,086 $ 29,086 (1) Included in cash and cash equivalents on our condensed consolidated balance sheet at March 31, 2018 and September 30, 2017 . Not included in these tables are cash deposits of $96.6 million and $90.3 million at March 31, 2018 and September 30, 2017 , respectively. (2) Represents securities held under a supplemental retirement and savings plan for senior management employees, which are distributed upon termination or retirement of the employees. Included in marketable securities on our condensed consolidated balance sheet at March 31, 2018 and September 30, 2017 . Where applicable, we use quoted prices in active markets for identical assets or liabilities to determine fair value. This pricing applies to our Level 1 investments. To the extent quoted prices in active markets for assets or liabilities are not available, the valuation techniques used to measure the fair values of our financial assets incorporate market inputs, which include reported trades, broker/dealer quotes, benchmark yields, issuer spreads, benchmark securities and other inputs derived from or corroborated by observable market data. This methodology would apply to our Level 2 investments. We have not changed our valuation techniques in measuring the fair value of any financial assets and liabilities during the period. For the fair value of our derivative instruments and senior notes, see Note 3 and Note 7, respectively.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Financial Instruments	Derivative Financial Instruments We use derivative instruments to manage risks caused by fluctuations in foreign exchange rates. The primary objective of our derivative instruments is to protect the value of foreign-currency-denominated receivable and cash balances from the effects of volatility in foreign exchange rates that might occur prior to conversion to their respective functional currencies. We principally utilize foreign currency forward contracts, which enable us to buy and sell foreign currencies in the future at fixed exchange rates and economically offset changes in foreign exchange rates. We routinely enter into contracts to offset exposures denominated in the British pound, Euro, and Singapore dollar. Foreign-currency-denominated receivable and cash balances are remeasured at foreign exchange rates in effect on the balance sheet date with the effects of changes in foreign exchange rates reported in other income (expense), net. The forward contracts are not designated as hedges and are marked to market through other income (expense), net. Fair value changes in the forward contracts help mitigate the changes in the value of the remeasured receivable and cash balances attributable to changes in foreign exchange rates. The forward contracts are short-term in nature and typically have average maturities at inception of less than three months . The following tables summarize our outstanding foreign currency forward contracts, by currency, at March 31, 2018 and September 30, 2017 : March 31, 2018 Contract Amount Fair Value Foreign Currency US$ US$ (In thousands) Sell foreign currency: Euro (EUR) EUR 5,250 $ 6,506 $ — Buy foreign currency: British pound (GBP) GBP 6,556 $ 9,250 $ — Singapore dollar (SGD) SGD 8,363 $ 6,400 $ — September 30, 2017 Contract Amount Fair Value Foreign Currency US$ US$ (In thousands) Sell foreign currency: Euro (EUR) EUR 5,050 $ 5,968 $ — Buy foreign currency: British pound (GBP) GBP 9,341 $ 12,500 $ — The foreign currency forward contracts were entered into on March 31, 2018 and September 30, 2017 , respectively; therefore, their fair value was $0 on each of these dates.

Interest on amounts borrowed under the credit facility is based on (i) a base rate, which is the greater of (a) the prime rate, (b) the Federal Funds rate plus 0.500% and (c) the one-month LIBOR rate plus 1.000% , plus, in each case, an applicable margin, or (ii) an adjusted LIBOR rate plus an applicable margin. The applicable margin for base rate borrowings ranges from 0% to 0.875% and for LIBOR borrowings ranges from 1.000% to 1.875% , and is determined based on our consolidated leverage ratio. In addition, we must pay credit facility fees. The credit facility contains certain restrictive covenants including maintaining a minimum fixed charge ratio of 2.5 and a maximum consolidated leverage ratio of 3.0 , subject to a step up to 3.5 following certain permitted acquisitions. The credit agreement also contains other covenants typical of unsecured facilities. As of March 31, 2018 , we had $460.0 million in borrowings outstanding at a weighted average interest rate of 2.973% , of which $400.0 million was classified as a long-term liability and recorded in long-term debt within the accompanying condensed consolidated balance sheets. We were in compliance with all financial covenants under this credit facility as of March 31, 2018 . Depending on market conditions, we may refinance some of our debt in 2018.

The outstanding 2010 Senior Notes’ weighted average interest rate is 5.6% and the weighted average maturity is 9.8 years . The Senior Notes require interest payments semi-annually and contain certain restrictive covenants, including the maintenance of consolidated net debt to consolidated EBITDA ratio and a fixed charge coverage ratio. The purchase agreements for the Senior Notes also contain certain covenants typical of unsecured facilities. As of March 31, 2018 , we were in compliance with all financial covenants.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate The effective income tax rate was 20.9% and 24.3% during the quarters ended March 31, 2018 and 2017 , respectively, and 20.3% and (1.9)% during the six months ended March 31, 2018 and 2017, respectively. The provision for income taxes during interim quarterly reporting periods is based on our estimates of the effective tax rates for the full fiscal year. The effective tax rate in any quarter can also be affected positively or negatively by adjustments that are required to be reported in the specific quarter of resolution. The effective tax rate for the six months ended March 31, 2018 was significantly impacted by recording the impact of the Tax Cuts and Jobs Act (the “Tax Act”), enacted on December 22, 2017 by the U.S. government. The Tax Act makes broad and complex changes to the U.S. tax code that will affect our fiscal year ended September 30, 2018, including, but not limited to, (1) reducing the U.S. federal corporate tax rate and (2) requiring a one-time transition tax on certain un-repatriated earnings of foreign subsidiaries that is payable over eight years. The Tax Act reduces the federal corporate tax rate to 21.0% effective January 1, 2018. In accordance with Section 15 of the Internal Revenue Code, we will utilize a blended rate of 24.5% for our fiscal 2018 tax year, by applying a prorated percentage of the number of days prior to and subsequent to the January 1, 2018 effective date. We recorded provisional charges for the re-measurement of the deferred tax assets of $5.6 million to our income tax expense related to long-term deferred tax assets and $3.0 million related to short-term deferred tax assets during the six months ended March 31, 2018. The Deemed Repatriation Transition Tax (the “Transition Tax”) is a tax on previously untaxed accumulated earnings and profits (“E&P”) of certain of our foreign subsidiaries. To determine the amount of the Transition Tax, we must determine, in addition to other factors, the amount of post-1986 E&P of the relevant subsidiaries, as well as the amount of non-U.S. income taxes paid on such earnings. As of March 31, 2018, we are able to make a reasonable estimate and recorded a provisional Transition Tax obligation of $4.9 million . On December 22, 2017, the SEC issued Staff Accounting Bulletin (“SAB 118”), which provides guidance on accounting for tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate to be included in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provision of the tax laws that were in effect immediately before the enactment of the Tax Act. While we are able to make reasonable estimates of the impact of the reduction in corporate rate and the deemed repatriation transition tax, the final impact of the Tax Act may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the I.R.S., and actions we may take. W e are continuing to gather additional information to determine the final impact. The total unrecognized tax benefit for uncertain tax positions is estimated to be $6.4 million and $6.5 million at March 31, 2018 and September 30, 2017 , respectively. We recognize interest expense related to unrecognized tax benefits and penalties as part of the provision for income taxes in our condensed consolidated statements of income and comprehensive income. We have accrued interest of $0.5 million and $0.4 million related to unrecognized tax benefits as of March 31, 2018 and September 30, 2017 , respectively.

Segment Reporting [Abstract]
Segment Information	Segment Information We are organized into the following three operating segments, each of which is a reportable segment, to align with internal management of our worldwide business operations based on product offerings. • Applications . This segment includes pre-configured decision management applications designed for a specific type of business problem or process — such as marketing, account origination, customer management, fraud, collections and insurance claims management — as well as associated professional services. These applications are available to our customers as on-premises software, and many are available as hosted, software-as-a-service (“SaaS”) applications through the FICO ® Analytic Cloud. • Scores. This segment includes our business-to-business scoring solutions, our myFICO ® solutions for consumers and associated professional services. Our scoring solutions give our clients access to analytics that can be easily integrated into their transaction streams and decision-making processes. Our scoring solutions are distributed through major credit reporting agencies, as well as services through which we provide our scores to clients directly. • Decision Management Software. This segment is composed of analytic and decision management software tools that clients can use to create their own custom decision management applications, our new FICO ® Decision Management Suite, as well as associated professional services. These tools are available to our customers as on-premises software or through the FICO ® Analytic Cloud. Our Chief Executive Officer evaluates segment financial performance based on segment revenues and segment operating income. Segment operating expenses consist of direct and indirect costs principally related to personnel, facilities, consulting, travel and depreciation. Indirect costs are allocated to the segments generally based on relative segment revenues, fixed rates established by management based upon estimated expense contribution levels and other assumptions that management considers reasonable. We do not allocate broad-based incentive expense, share-based compensation expense, restructuring expense, amortization expense, various corporate charges and certain other income and expense measures to our segments. These income and expense items are not allocated because they are not considered in evaluating the segment’s operating performance. Our Chief Executive Officer does not evaluate the financial performance of each segment based on its respective assets, nor capital expenditures where depreciation amounts are allocated to the segments from their internal cost centers as described above.

Contingencies	Contingencies We are in disputes with certain customers regarding amounts owed in connection with the sale of certain of our products and services. We also have had claims asserted by former employees relating to compensation and other employment matters. We are also involved in various other claims and legal actions arising in the ordinary course of business. We record litigation accruals for legal matters which are both probable and estimable. For legal proceedings for which there is a reasonable possibility of loss (meaning those losses for which the likelihood is more than remote but less than probable), we have determined we do not have material exposure on an aggregate basis.

Fair Isaac Corporation	Fair Isaac Corporation Incorporated under the laws of the State of Delaware, Fair Isaac Corporation (“FICO”) is a provider of analytic, software and data management products and services that enable businesses to automate, improve and connect decisions. FICO provides a range of analytical solutions, credit scoring and credit account management products and services to banks, credit reporting agencies, credit card processing agencies, insurers, retailers, telecommunications providers, pharmaceutical companies, healthcare organizations, public agencies and organizations in other industries.
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation We have prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q and the applicable accounting guidance. Consequently, we have not necessarily included all information and footnotes required for audited financial statements. In our opinion, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our financial position and results of operations. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with our audited consolidated financial statements and notes thereto presented in our Annual Report on Form 10-K for the year ended September 30, 2017 . The interim financial information contained in this report is not necessarily indicative of the results to be expected for any other interim period or for the entire fiscal year. The condensed consolidated financial statements include the accounts of FICO and its subsidiaries. All intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates We make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures made in the accompanying notes. For example, we use estimates in determining the collectability of accounts receivable; the appropriate levels of various accruals; labor hours in connection with fixed-fee service contracts; the amount of our tax provision and the realizability of deferred tax assets. We also use estimates in determining the remaining economic lives and carrying values of acquired intangible assets, property and equipment, and other long-lived assets. In addition, we use assumptions to estimate the fair value of reporting units and share-based compensation. Actual results may differ from our estimates.
New Accounting Pronouncements	New Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09, “ Revenue from Contracts with Customers (Topic 606) ” (“ASU 2014-09”). ASU 2014-09 requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will replace most existing revenue recognition guidance in U.S. Generally Accepted Accounting Principles when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts. In August 2015, the FASB issued ASU No 2015-14, “ Deferral of the Effective Date ” (“ASU 2015-14”), which defers the effective date for ASU 2014-09 by one year. For public entities, the guidance in ASU 2014-09 will be effective for annual reporting periods beginning after December 15, 2017 (including interim reporting periods within those periods), which means it will be effective for our fiscal year beginning October 1, 2018. Early adoption is permitted to the original effective date of December 15, 2016 (including interim reporting periods within those periods). In March 2016, the FASB issued ASU No. 2016-08, “ Principal versus Agent Considerations (Reporting Revenue versus Net) ” (“ASU 2016-08”), which clarifies the implementation guidance on principal versus agent considerations in the new revenue recognition standard. In April 2016, the FASB issued ASU No. 2016-10, “ Identifying Performance Obligations and Licensing ” (“ASU 2016-10”), which reduces the complexity when applying the guidance for identifying performance obligations and improves the operability and understandability of the license implementation guidance. In May 2016, the FASB issued ASU No. 2016-12 “ Narrow-Scope Improvements and Practical Expedients ” (“ASU 2016-12”), which amends the guidance on transition, collectability, noncash consideration and the presentation of sales and other similar taxes. In December 2016, the FASB further issued ASU 2016-20, “ Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers ” (“ASU 2016-20”), which makes minor corrections or minor improvements to the Codification that are not expected to have a significant effect on current accounting practice or create a significant administrative cost to most entities. The amendments are intended to address implementation issues that were raised by stakeholders and provide additional practical expedients to reduce the cost and complexity of applying the new revenue standard. These amendments have the same effective date as the new revenue standard. We have established a cross-functional implementation team consisting of representatives across the organization to address the scope of work required to implement the recognition and disclosure requirements under the new standard. This cross-functional implementation team has developed a project plan, which includes evaluating customer contracts across the organization, developing policies, processes and tools to report financial results, and implementing and evaluating our internal controls over financial reporting that will be necessary under the new standard. We currently plan to adopt Topic 606 in the first quarter of our fiscal 2019 using the retrospective transition method. Our ability to adopt Topic 606 using the full retrospective method is dependent on system readiness, and the completion of our analysis of information necessary to restate prior period financial statements. As we continue to assess the new standard along with industry trends and additional interpretive guidance, we may adjust our implementation plan accordingly. We are continuing to assess the impact of adopting Topic 606 on our consolidated financial statements and believe the new standard will impact the following policies and disclosures: • Timing of revenue recognition of license revenue on term licenses and transactional revenue on guaranteed minimum fees related to our on-premises software products. Under the new standard, we expect to recognize revenue when control of the license is transferred to the customer, rather than at the date payments become due and payable or ratably over the term of the contract required under the current standard; • Presentation of contract balances. Under the new standard, when we enter into noncancellable contracts that provide unconditional rights to payment from our customers for services that we have not yet completed providing or services we will provide in the near future, we expect to present the unconditional rights as receivables, regardless of whether cash has been received from customers; • Required disclosures including information about remaining transaction price and when we expect to recognize revenue; and • Accounting for commissions under the new standard will result in the deferral of incremental commission costs for obtaining contracts. We do not currently expect Topic 606 to have a significant effect on the timing of revenue recognition for our maintenance or professional services revenues, or SaaS contracts. In October 2016, the FASB issued ASU No. 2016-16, “ Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory ” (“ASU 2016-16”). ASU 2016-16 requires an entity to recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The guidance is effective for fiscal years and interim periods beginning after December 15, 2017, which means it will be effective for our fiscal year beginning October 1, 2018. ASU 2016-16 should be applied on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings at the beginning of the period of adoption. Early adoption is permitted as of the beginning of an annual reporting period for which financial statements (interim or annual) have not been issued. We do not believe that adoption of ASU 2016-16 will have a significant impact on our consolidated financial statements. In February 2016, the FASB issued ASU 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. ASU 2016-02 is effective for fiscal years and interim periods within those fiscal years beginning after December 15, 2018, which means it will be effective for our fiscal year beginning October 1, 2019. Early adoption is permitted. We are currently evaluating the timing of our adoption and the impact that the updated standard will have on our consolidated financial statements.
