Nature of Business	6 Months Ended
Nature of Business	Mar. 31, 2015
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 in this Form 10-Q all information and footnotes required for audited financial statements. In our opinion, the accompanying unaudited interim condensed consolidated financial statements in this Form 10-Q 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, 2014. 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 collectibility 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 Recently Issued or Adopted 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. Early adoption is not permitted. ASU 2014-09 is effective for fiscal years and interim periods within those years, beginning on or after December 15, 2016, which means it will be effective for our fiscal year beginning October 1, 2017. We have not yet selected a transition method and we are currently evaluating the impact that the updated standard will have on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance" ("ASU 2015-03"), which changes the presentation of debt issuance costs in financial statements. Under ASU 2015-03, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs is reported as interest expense. ASU 2015-03 is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2015, which means it will be effective for our fiscal year beginning October 1, 2016. Early adoption is permitted. We do not believe that adoption of ASU 2015-03 will have a significant impact on our consolidated financial statements.

Business Combinations [Abstract]

Business Combinations

On January 12, 2015, we acquired 100% of the equity of TONBELLER Aktiengesellschaft ("TONBELLER"). TONBELLER is an innovative provider of financial crime and compliance ("FCC") solutions that support the demanding regulatory compliance requirements of more than a thousand banks and commercial organizations. This acquisition will allow us to capitalize on the escalating demand for new, risk-based, integrated FCC solutions.

The purchase price allocation as of the date of the acquisition was based on a preliminary valuation and is subject to revision as more detailed analyses are completed and additional information about the fair value of assets acquired and liabilities assumed become available. The major classes of assets and liabilities to which we have preliminarily allocated the purchase price are as follows:



	(In thousands)
Consideration

Cash	$	59,640

Acquisition-related costs (included in the company’s condensed consolidated statement of income for the quarter and six months ended March 31, 2015 as a component of selling, general and administrative expenses)	$	486

Recognized amounts of identifiable assets acquired and liabilities assumed

Cash and cash equivalents	$	2,640
Accounts receivable, net	5,389
Prepaid expenses and other current assets	209
Intangible assets:
Completed technology	2,700
Customer relationships	11,600
Trade names	600
Other assets	112
Accounts payable	(1,118		)
Accrued compensation and employee benefits	(1,493		)
Other accrued liabilities	(2,838		)
Deferred income taxes	(4,349		)
Total identifiable net assets	13,452

Goodwill	46,188
Total	$	59,640

The acquired identifiable intangible assets have a weighted average useful life of approximately 4.9 years and are being amortized using the straight-line method over their estimated useful lives as follows: completed technology, five years; customer relationships, five years; and trade names, three years. The goodwill of $46.2 million arising from the acquisition consists largely of the revenue synergies related to market expansion and more rapid innovation for our solutions. The goodwill was allocated to our Applications segment and is not deductible for tax purposes. TONBELLER has been included in our operating results since the acquisition date. The pro forma impact of this acquisition was not deemed material to our results of operations.

Fair Value Disclosures [Abstract]

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, 2015 and September 30, 2014.

•

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, 2015 and September 30, 2014.

The following tables represent financial assets that we measured at fair value on a recurring basis at March 31, 2015 and September 30, 2014:



March 31, 2015	Active Markets for Identical Instruments (Level 1)		Fair Value as of March 31, 2015

Marketable securities (2)	8,751		8,751
Total	$	19,077	$	19,077


(1)	Included in cash and cash equivalents on our condensed consolidated balance sheet at March 31, 2015 and September 30, 2014. Not included in these tables are cash deposits of $86.4 million and $94.7 million at March 31, 2015 and September 30, 2014, 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 available for sale on our condensed consolidated balance sheet at March 31, 2015 and September 30, 2014.

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 4 and Note 8 to the condensed consolidated financial statements, respectively.

Derivative Financial Instruments

Derivative Instruments and Hedging Activities Disclosure [Abstract]

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 Canadian 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, 2015 and September 30, 2014:



	March 31, 2015
	Contract Amount				Fair Value
	Foreign Currency		US$		US$

The foreign currency forward contracts were entered into on March 31, 2015 and September 30, 2014, respectively; therefore, their fair value was $0 on each of these dates.

Revolving Line of Credit	6 Months Ended
Revolving Line of Credit	Mar. 31, 2015
Debt Disclosure [Abstract]
Revolving Line of Credit	Revolving Line of Credit We have a $400 million unsecured revolving line of credit with a syndicate of banks that expires on December 30, 2019. Proceeds from the credit facility can be used for working capital and general corporate purposes and may also be used for the refinancing of existing debt, acquisitions and the repurchase of our common stock. 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, 2015, we had $211.0 million in borrowings outstanding at a weighted average interest rate of 1.555%, of which $200.0 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, 2015.

Debt Disclosure [Abstract]
Senior Notes	Senior Notes On May 7, 2008, we issued $275 million of senior notes in a private placement to a group of institutional investors (the “2008 Senior Notes”). The 2008 Senior Notes were issued in four series with maturities ranging from 5 to 10 years. The outstanding 2008 Senior Notes’ weighted average interest rate is 7.0% and the weighted average maturity is 9.0 years. On July 14, 2010, we issued $245 million of senior notes in a private placement to a group of institutional investors (the “2010 Senior Notes” and, with the 2008 Senior Notes, the “Senior Notes”). The 2010 Senior Notes were issued in four series with maturities ranging from 6 to 10 years. The 2010 Senior Notes’ weighted average interest rate is 5.2% and the weighted average maturity is 8.0 years. The Senior Notes require interest payments semi-annually and also include certain restrictive covenants. As of March 31, 2015, we were in compliance with all financial covenants which include the maintenance of consolidated net debt to consolidated EBITDA ratio and a fixed charge coverage ratio. The issuance of the Senior Notes also required us to make certain covenants typical of unsecured facilities. The carrying value of the Senior Notes was $447.0 million as of March 31, 2015 and September 30, 2014. The fair value of the Senior Notes was $465.8 million and $462.7 million as of March 31, 2015 and September 30, 2014, respectively. We measure the fair value of the Senior Notes based on Level 2 inputs, which include quoted market prices and interest rate spreads of similar securities.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Effective Tax Rate The effective income tax rate was 27.5% and 33.7% during the quarters ended March 31, 2015 and 2014, respectively and 25.0% and 35.5% during the six months ended March 31, 2015 and 2014, respectively. The provision for income taxes during interim quarterly reporting periods is based on our estimates of the effective tax rates for the respective 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 decrease in our effective tax rate year over year was primarily due to the retroactive extension of the U.S. Federal Research and Development Credit through 2014, which was enacted during the first quarter of our fiscal 2015, as well as a higher percentage of revenue expected in lower taxing jurisdictions. The total unrecognized tax benefit for uncertain tax positions is estimated to be approximately $5.0 million and $4.6 million at March 31, 2015 and September 30, 2014, 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 $0.6 million and $0.5 million, related to unrecognized tax benefits as of March 31, 2015 and September 30, 2014, respectively.

We exclude the options to purchase shares of common stock in the computation of the diluted EPS where the options’ exercise price exceeds the average market price of our common stock as their inclusion would be antidilutive. There were approximately 46,000 and 14,000 options excluded for the quarters ended March 31, 2015 and 2014, respectively. There were approximately 270,000 and 7,000 options excluded for the six months ended March 31, 2015 and 2014, respectively.

Segment Reporting [Abstract]

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. Our Applications products are pre-configured decision management applications and associated professional services, designed for a specific type of business problem or process, such as marketing, account origination, customer management, fraud and insurance claims management.

•

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.


•	Tools. The Tools segment is composed of software tools and associated professional services that clients can use to create their own custom decision management applications.

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 or capital expenditures; rather, depreciation amounts are allocated to the segments from their internal cost centers as described above.

Commitments and Contingencies Disclosure [Abstract]
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.

Nature of Business (Policies)	6 Months Ended
Nature of Business (Policies)	Mar. 31, 2015
Accounting Policies [Abstract]
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. 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	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 in this Form 10-Q all information and footnotes required for audited financial statements. In our opinion, the accompanying unaudited interim condensed consolidated financial statements in this Form 10-Q 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, 2014. 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 collectibility 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 Recently Issued or Adopted	New Accounting Pronouncements Recently Issued or Adopted 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. Early adoption is not permitted. ASU 2014-09 is effective for fiscal years and interim periods within those years, beginning on or after December 15, 2016, which means it will be effective for our fiscal year beginning October 1, 2017. We have not yet selected a transition method and we are currently evaluating the impact that the updated standard will have on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Simplifying the Presentation of Debt Issuance" ("ASU 2015-03"), which changes the presentation of debt issuance costs in financial statements. Under ASU 2015-03, an entity presents such costs in the balance sheet as a direct deduction from the related debt liability rather than as an asset. Amortization of the costs is reported as interest expense. ASU 2015-03 is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2015, which means it will be effective for our fiscal year beginning October 1, 2016. Early adoption is permitted. We do not believe that adoption of ASU 2015-03 will have a significant impact on our consolidated financial statements.
