FORWARD LOOKING STATEMENTS

Statements contained in this Report that are not statements of historical fact should be considered forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 (the “Act”). In addition, certain statements in our future filings with the Securities and Exchange Commission (“SEC”), in press releases, and in oral and written statements made by us or with our approval that are not statements of historical fact constitute forward-looking statements within the meaning of the Act. Examples of forward-looking statements include, but are not limited to: (i) projections of revenue, income or loss, earnings or loss per share, the payment or nonpayment of dividends, capital structure and other statements concerning future financial performance; (ii) statements of our plans and objectives by our management or Board of Directors, including those relating to products or services; (iii) statements of assumptions underlying such statements; (iv) statements regarding business relationships with vendors, customers or collaborators; and (v) statements regarding products, their characteristics, performance, sales potential or effect in the hands of customers. Words such as “believes,” “anticipates,” “expects,” “intends,” “targeted,” “should,” “potential,” “goals,” “strategy,” and similar expressions are intended to identify forward-looking statements, but are not the exclusive means of identifying such statements. Forward-looking statements involve risks and uncertainties that may cause actual results to differ materially from those in such statements. Factors that could cause actual results to differ from those discussed in the forward-looking statements include, but are not limited to, those described in Item 1A, Risk Factors, below. The performance of our business and our securities may be adversely affected by these factors and by other factors common to other businesses and investments, or to the general economy. Forward-looking statements are qualified by some or all of these risk factors. Therefore, you should consider these risk factors with caution and form your own critical and independent conclusions about the likely effect of these risk factors on our future performance. Such forward-looking statements speak only as of the date on which statements are made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made to reflect the occurrence of unanticipated events or circumstances. Readers should carefully review the disclosures and the risk factors described in this and other documents we file from time to time with the SEC, including our reports on Forms 10-Q and 8-K to be filed by the Company in fiscal 2007.

PRODUCTS AND SERVICES

We help businesses automate and improve decisions across the enterprise, an approach we commonly refer to as Enterprise Decision Management, or “EDM”. Most of our solutions address customer decisions, including customer targeting and acquisition, account origination, customer management, fraud, collections and recovery. We also help businesses improve non-customer decisions such as transaction and claims processing, and network integrity review. Our solutions enable users to make decisions that are more precise, consistent and agile, and that systematically advance business goals. This helps our clients to reduce the cost of doing business, increase revenues and profitability, reduce losses from risks and fraud, and increase customer loyalty.

Our Segments

We deliver EDM through products and services that we categorize into the following four operating segments:

•  Strategy Machine^tm Solutions.  These are pre-configured EDM applications designed for a specific type of business problem or process, such as marketing, account origination, customer management, fraud and medical bill review. This segment also includes our myFICO solutions for consumers.

•  Scoring Solutions.  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 lenders directly.

•  Professional Services.  Through our professional services, we tailor our EDM products to our clients’ environments, and we design more effective decisioning environments for our clients. This segment includes revenues from custom engagements, business solution and technical consulting services, systems integration services, and data management services.

•  Analytic Software Tools.  This segment is composed of software tools that clients can use to create their own custom EDM applications.

Comparative segment revenues, operating income and related financial information for fiscal 2006, 2005 and 2004 are set forth in Note 16 to the accompanying consolidated financial statements.

Our Solutions

Our solutions involve three fundamental disciplines:

•  Analytics to identify the risks and opportunities associated with individual clients, prospects and transactions, in order to detect patterns such as fraud, and to improve the design of decision logic or “strategies”;

•  Data management, profiling and text recognition that bring extensive customer information to every decision; and

•  Software such as rules management systems that implement business rules, models and decision strategies, often in a real-time environment.

All of our solutions are designed to help businesses make decisions that are faster, more precise, more consistent and more agile, while reducing costs and risks incurred in making decisions.

Strategy Machine Solutions

We develop industry-tailored EDM applications, which we call Strategy Machine Solutions, that apply analytics, data management and decision management software to specific business challenges and processes. These include credit offer prescreening, medical bill review, telecommunications fraud prevention and others. Our Strategy Machine Solutions serve clients in the financial services, insurance, healthcare, retail, telecommunications and government sectors.

Marketing Strategy Machine Solutions

The chief Strategy Machine offering for marketing is our Fair Isaac MarketSmart Decision System^® solution (“MarketSmart”). The MarketSmart solution is a suite of products and capabilities designed to integrate all of the technology and analytic services needed to perform context-sensitive customer acquisition, cross-selling and retention programs. The MarketSmart solution enables companies that offer multiple products and use multiple channels (companies such as large financial institutions, consumer branded goods companies, pharmaceutical companies, retail merchants and telecommunications service providers) to execute more efficient and profitable customer interactions. Services offered under the MarketSmart brand name include customer data integration (“CDI”) services; services that use transaction analytics to identify customer patterns and help clients target their marketing activities; services that enable real-time marketing through direct consumer interaction channels; campaign management and optimization services; interactive tools that automate the design, execution and collection of customer response data across multiple channels; and customer data collection, management and profiling services.

A number of our marketing services are designed for specific industries, such as retail and pharmaceuticals. For example, our services for retailers include using analytics to help retailers identify and market to their store shoppers; analyzing transaction data to provide insights into store customer activity and compare it with sales

4

pattern activity across the marketplace; and analyzing a retailer’s purchase transaction data to help them understand buying patterns, sequences and contexts.

Originations Strategy Machine Solutions

We provide solutions that enable banks, credit unions, finance companies, installment lenders, telecommunications service providers and other companies to automate and improve the processing of requests for credit or service. These solutions increase the speed and efficiency with which requests are handled, reduce losses and increase approval rates through analytics that assess applicant risk, and reduce the need for manual review by loan officers.

Our solutions include the web-based LiquidCredit^® service, which is primarily focused on the credit decision and offered largely to mid-tier financial services institutions, e-commerce providers and telecommunications providers; and Capstone^® Decision Manager, a complete end-user software solution for application decisioning and processing. In fiscal 2005, we introduced new components for the Capstone system that can be used with multiple originations platforms and environments. These components are Capstone Decision Accelerator, which is a rules-based application based on our Blaze Advisor^tm system, and Capstone Intelligent Data Manager, which enables lenders to access data from several consumer and small business credit data sources. We also offer custom and consortium-based credit risk and application fraud models.

Customer Management Strategy Machine Solutions

Our customer management products and services enable businesses to automate and improve decisions on their existing customers. These solutions help businesses decide which customers to cross-sell, what additional products and services to offer, whether customer risk levels have increased or decreased, when and how much to change a customer’s credit line, what pricing adjustments to make in response to account performance or promotional goals, and how to treat delinquent and high-risk accounts.

We provide customer management solutions for:

•  Financial Services.  In financial services, our leading account and customer management product is the TRIAD^tm adaptive control system. Our adaptive control systems are so named because they enable businesses to rapidly adapt to changing business and internal conditions by designing and testing new strategies in a “champion/challenger” environment. The TRIAD system is the world’s leading credit account management system, and our adaptive control systems are used by more than 250 issuers worldwide to manage approximately 65% of the world’s credit card accounts. Our latest version of the TRIAD system enables users to manage risk and communications at both the account and borrower level from a single platform. We also offer transaction-based neural network (the term neural network is defined under “Technology” later in this section) models called TRIAD Transaction Scores that help card issuers identify high-risk behavior more quickly and thus manage their credit card accounts more profitably. We market and sell TRIAD end-user software licenses, maintenance, consulting services, and strategy design and evaluation. Additionally, we provide TRIAD services and similar credit account management services through 12 third-party credit card processors worldwide, including the two largest processors in the U.S., First Data Resources, Inc. and Total System Services, Inc. We also provide the TRIAD system as a hosted service in Application Service Provider (“ASP”) mode.

•  Telecommunications.  The TelAdaptive^® account management system offers telecommunications service providers account management functionality similar to the TRIAD system, including receivables risk management, account spending limits, churn management and cross-sell communications.

•  Insurance.  We provide property and casualty insurers with decision management solutions that enable them to create, test and implement decision strategies for areas such as cross-selling, pricing, claims handling, retention, prospecting and underwriting.

Fraud Strategy Machine Solutions

Our fraud products improve our clients’ profitability by predicting the likelihood that a customer account is experiencing fraud. Our fraud products analyze customer transactions in real time and generate recommendations for immediate action, which is critical to stopping fraud and abuse. These applications can also detect some organized fraud schemes that are too complex and well-hidden to be identified by other methods.

Our solutions are designed to detect and prevent a wide variety of fraud and risk types across multiple industries, including credit and debit payment card fraud; identity fraud; telecommunications subscription fraud, technical fraud and bad debt; healthcare fraud; Medicaid and Medicare fraud; and property and casualty insurance fraud, including workers’ compensation fraud. Fair Isaac fraud solutions protect merchants, financial institutions, insurance companies, telecommunications carriers, government agencies and employers from losses and damaged customer relationships caused by fraud.

Our leading fraud detection solution is Falcon^tm Fraud Manager, recognized as the leader in global payment card fraud detection. Falcon Fraud Manager’s neural network predictive models and patented profiling technology, both further described below in the “Technology” section, examine transaction, cardholder and merchant data to detect a wide range of credit and debit card fraud quickly and accurately. Falcon Fraud Manager analyzes card transactions in real time, assesses the risk of fraud, and takes the user-defined steps to prevent fraud while expediting legitimate transactions. Falcon Fraud Manager protects hundreds of millions of active credit and debit card accounts, and is used in approximately 65% of all credit card transactions worldwide.

Fraud Predictor with Merchant Profiles is used in conjunction with Falcon Fraud Manager to improve fraud detection rates by analyzing merchant profile data. The merchant profiles include characteristics that reveal, for example, merchants that have a history of higher fraud volumes, and which purchase types and ticket sizes have most often been fraudulent at a particular merchant.

Falcon ID solution enables lenders and telecommunications service providers to control identity fraud across the customer lifecycle. Falcon ID relies on multiple sources of data and complex statistical modeling techniques to identify activity that is at high risk of stemming from identity theft. It also provides business rules management that companies can use to identify and resolve cases that appear to involve identity theft.

In addition to the Falcon products for financial services institutions, we offer CardAlert Fraud Manager. CardAlert Fraud Manager is a solution for fighting debit and ATM fraud in the U.S. The CardAlert service identifies and reports counterfeit payment cards to issuers before the majority of them incur fraud losses. The service analyzes daily transactions across multiple financial institutions, and uses this data to pinpoint multi-card fraud and identify common points of compromise.

We also provide a set of Fraud/Risk Analytics for Telecom solutions that are specifically designed to help telecommunications service providers reduce losses in four key areas. The bad debt solution is used to mitigate early-life and ongoing bad debt. The fraud solution is used to reduce complex types of fraud such as subscription fraud, technical fraud, internal fraud, dealer/agent fraud, calling card fraud, cloning and clip-on fraud. The revenue assurance solution predicts revenue leakage in the switch data collection, data mediation and billing/rating system phases. And the network assurance solution predicts problems in a telecommunications network by detecting intrusion, abuse or network integrity compromises. In addition, we offer RoamEx Roamer Data Exchanger, which delivers near real-time exchange of roamer call records that occur when subscribers roam outside a carrier’s home network. RoamEx Roamer Data Exchanger is used to exchange more than 90% of North American wireless carriers’ roamer call detail records.

Collections & Recovery Strategy Machine Solutions

Our leading solutions in this area are the Debt Manager^tm solution and the Recovery Management System^tm (“RMS^tm”) solution. The Debt Manager solution automates the full cycle of collections and recovery, including early collections, late collections, asset disposal, agency placement, recovery, litigation, bankruptcy, asset management and residual balance recovery. The RMS solution is focused on the later phases of distressed debt management, including bankruptcy and agency management. Companies using the Debt Manager and RMS solutions can access partner services such as collection agencies and attorneys via the ScoreNet^® network (formerly

6

BridgeLink^tm), which provides web-based access to and from thousands of third-party collections and recovery service providers, as well as access to multiple data sources and Fair Isaac solutions hosted in ASP mode.

Other solutions for collections and recovery include the PlacementsPlus service, an account placement optimization and management system; the Placement Optimizer^® service, which uses artificial intelligence-based analytics used to identify the agency that is likely to collect the most for each account; and custom collection and recovery models implemented in an ASP environment. Those analytic-based solutions can also be delivered via the ScoreNet network.

Mortgage Banking Strategy Machine Solutions

Fair Isaac provides end-to-end mortgage lending solutions that mortgage lenders can use to improve their loan marketing, sourcing, originations, servicing and default management. These solutions include the Diamond loan origination solution, an internet-based solution that streamlines the complete mortgage process; the LSAMS^tm loan servicing and account management system for the servicing of mortgage and consumer loans; FORTRACS software for default management; and the LenStar^tm default management communication network for attorney referrals. This category also includes our TCL^tm (The Construction Lender) solution, which enables lenders to manage the entire construction lending process. All of the mortgage solutions are integrated with Fair Isaac’s ScoreNet network (formerly BridgeLink), which provides real-time connectivity to a broad range of third-party service providers, business partners and external systems involved in the complex process of mortgage lending.

Insurance and Healthcare Strategy Machine Solutions

We provide software solutions and services that automate the review and repricing of medical bills for workers’ compensation and automobile medical injuries. Using these solutions, property and casualty insurers can automatically review and reprice a significant percentage of medical bills without human intervention. This allows for greater consistency and accuracy, which are important factors for regulatory compliance.

Our principal solutions in this area are:

•  Fair Isaac SmartAdvisor^tm medical bill review software.  The Fair Isaac SmartAdvisor solution provides medical bill review and repricing for workers’ compensation and automobile medical injury claims. It checks each bill against an extensive database of state fee schedules, automated contracts and user-defined policies to help insurers and others get the maximum savings on every bill reviewed. The SmartAdvisor software uses our business rules management technology to increase the speed, accuracy and consistency of decisions and reduce labor costs. It is available in both licensed client/server and ASP versions.

•  Insurance Service Bureau.  Utilizing Fair Isaac’s medical bill review software, we provide turnkey insurance bill review administration services at selected locations across the country. These service bureau operations offer expert medical bill and preferred provider review for workers’ compensation and auto medical insurance bills, including the additional review of complex medical, hospital and surgical bills.

We also provide fraud solutions for different segments of the insurance healthcare market. Our principal solutions in this area are:

•  Payment Optimizer^® fraud detection system, which provides both prepayment claims scoring and retrospective analysis to help payers reduce fraud losses and ensure payment integrity.

•  VeriComp^® Fraud Manager software, which uses neural networks and data analysis to identify potentially fraudulent workers’ compensation claims that need investigation or special handling.

Additionally, we serve the insurance claims management market through our MIRA^tm Claims Advisor product which uses predictive models to forecast appropriate claims reserves based on individual claim data. We also provide services that help healthcare payers reduce claims leakage and detect fraud, and that help hospitals determine payment strategies for patients during the admission process.

Consumer Strategy Machine Solutions

Through our myFICO^® division, we provide solutions based on our analytics to consumers, sold directly by us or through distribution partners. Consumers can use the myFICO.com website to purchase their FICO^® scores, the credit reports underlying the scores, explanations of the factors affecting their scores, and customized advice on how to improve their scores. Customers can also use the myFICO service to simulate how taking specific actions would affect their FICO^® score. The myFICO.com website is the only source for consumers to obtain their FICO^® scores and credit reports from all three of the major U.S. credit reporting agencies. Consumers can also purchase Score Watch^tm subscriptions, which deliver alerts via email and SMS or text messages when the user’s scores or balances change. The myFICO products and subscription offerings are available online at www.myfico.com, through two of the credit reporting agencies involved — Equifax Inc. (“Equifax”) and TransUnion Corporation (“TransUnion”) — and through lenders, financial portals and numerous other partners.

Scoring Solutions

We develop the world’s leading scores based on third-party data. Our FICO^® scores are used in most U.S. credit decisions, by most of the major credit card organizations as well as by mortgage and auto loan originators. These scores provide a consistent and objective measure of an individual’s credit risk. Credit grantors use the FICO^® scores to prescreen solicitation candidates, to evaluate applicants for new credit and to review existing accounts. The FICO^® scores are calculated based on proprietary scoring models. The scores produced by these models are available through each of the three major credit reporting agencies in the United States: TransUnion, Experian Information Solutions, Inc. (“Experian”), and Equifax. Users generally pay the credit reporting agencies scoring fees based on usage, and the credit reporting agencies share these fees with us.

The most powerful of our U.S. credit bureau products, NextGen FICO^® risk scores, are also available at all three major credit-reporting agencies. NextGen FICO^® risk scores provide a more refined risk assessment than the classic FICO^® risk scores.

We have expanded our scoring portfolio by analyzing data that is unavailable through the three major U.S. credit reporting agencies. The FICO^® Expansion^tm score provides scores on U.S. consumers who do not have traditional FICO^® scores, generally because they do not have any credit accounts being reported to the credit reporting agencies. The score analyzes multiple sources of non-traditional credit data accessed by our subsidiary, Fair Isaac Network, Inc., and the score and associated reports are provided to lenders through a subsidiary called Fair Isaac Credit Services, Inc. The Fair Isaac^® Qualify^tm score helps marketers find prospects on their promotional mailing lists who are most likely to respond and to be approved for credit. This score is based on commercially available sources of marketing data, and is delivered by Fair Isaac.

We also market a new score called the Global FICO^® score that extends our thorough analysis of multiple-lender credit data to countries around the world that have established credit bureaus. These scores help lenders assess the risk of prospects, applicants and borrowers, and are particularly valuable in markets where there is not a dominant credit bureau risk score available. So far lenders and credit bureaus in 13 countries across four continents are using or implementing the Global FICO^® score.

In addition to the scores noted above, we have developed marketing and bankruptcy scores offered through the U.S. credit reporting agencies; an application fraud and a bankruptcy score available in Canada; consumer risk scores offered through credit reporting agencies in Canada, South Africa and the U.K.; commercial credit scores delivered by both U.S. and U.K. credit reporting agencies; and a bankruptcy scoring service offered through ISC, a subsidiary of Visa USA.

We have also developed scoring systems for insurance underwriters and marketers. Such systems use the same underlying statistical technology as our FICO^® risk scores, but are designed to predict applicant or policyholder insurance loss risk for automobile or homeowners’ coverage. Our insurance scores are available in the U.S. from TransUnion, Experian, Equifax and ChoicePoint, Inc., and in Canada from Equifax. In fiscal 2005, we introduced a new kind of insurance score called the Property PredictR^tm score, which analyzes property inspection database data from an insurance services provider, Millennium Information Services, Inc., to calculate the loss risk of a property.

8

We also provide credit bureau scoring services and related consulting directly to users in financial services through two U.S.-based services: PreScore^® Service for prescreening solicitation candidates, and the FICO^® Score Delivery service (formerly known as ScoreNet Service) for customer account management.

Professional Services

We provide a variety of custom offerings, business solution and technical consulting services, systems integration services, and data management services to clients worldwide. The focus is on leveraging our industry experience and technical expertise, typically on a custom basis, to help clients address unique business challenges, to support the usage of our Strategy Machine^® Solutions and our analytic software tools, and to create new sales opportunities for our other offerings. This group also performs consultative selling, developing customized solution sets combining various products and capabilities to meet unique client or industry opportunities. These services are generally offered on an hourly or fixed fee basis.

In fiscal 2005, we acquired Braun Consulting, Inc. (“Braun”), a marketing strategy and technology consulting firm based in Chicago with offices in Boston and New York. As a result of this acquisition, we now offer a wider range of consulting services addressing business strategy, operational excellence and marketing best practice. This acquisition also increased our presence in the healthcare, retail and pharmaceutical industries.

Our services include:

•  Solution and technology consulting.  We help clients implement and use our solutions and technologies. These projects draw on our product knowledge, industry expertise and technical skills. Each project is delivered using our EDM consulting methodology.

•  Systems integration services.  We help clients manage customer relationships more successfully through integrated customer systems and personalized content delivery. To accomplish this, we create common web platforms that leverage internet technologies such as portals (both internal and external), enterprise content management, web services and enterprise application integration.

•  Data management services.  We help clients gain insight into their customers by enabling the access, analysis and application of corporate data and information. This work involves implementing enterprise-level data and decision management systems, including data warehouses and marts, campaign management tools, database marketing engines, rules-based decision engines and analytical applications.

•  Business strategy consulting.  We help companies improve business performance through the design and implementation of customer-centric growth strategies. Using qualitative and quantitative research techniques, we help businesses determine which customer segments they should be targeting, what the sales and service proposition should be for each segment, and how to address organizational issues to ensure project success. Another key focus is helping companies comply with regulations such as the New Basel Capital Accord.

•  Industry consulting.  We combine our knowledge of EDM technology with our consultants’ experience to address the specific needs of companies in the retail, pharmaceuticals, telecommunications, insurance, high-tech, travel/media/entertainment and healthcare industries. Our industry consultants provide a wide range of consulting services, including business strategy consulting and custom solutions development.

•  Strategy Science services.  Using our Strategy Science technology and related advanced analytic methodologies, we perform decision modeling and optimization projects for customer acquisition, customer management, fraud, collections and other areas. These projects apply data and proprietary algorithms to the design of customer treatment strategies.

•  Predictive Science services.  We perform custom predictive modeling and related analytic projects for clients in multiple industries. This work leverages our analytic methodologies and expertise to solve risk management and marketing challenges for a single business, using that business’s data and industry best practices to develop a highly customized solution.

9

•  Fraud consulting services.  We complement our fraud products with consulting engagements that help businesses benchmark their performance, assess areas to improve and adopt best practices and solutions aimed at reducing fraud losses. These engagements draw on Fair Isaac’s experience helping lenders and other parties worldwide bring fraud losses under control and implement more successful anti-fraud programs.

Analytic Software Tools

We provide end-user software products that businesses use to build their own tailored EDM applications. In contrast to our packaged Strategy Machine solutions developed for specific industry applications, our analytic software tools perform a single function — such as management of the rules and policies an enterprise uses to make decisions — that can be easily integrated within a variety of specialized industry applications.

We use these tools as common software components for our own EDM applications, described above in the Strategy Machine Solutions section. We also partner with third-party providers within given industry markets and with major software companies to embed our tools within existing applications. These tools are sold as licensed software.

The principal products offered are software tools for:

•  Rules Management.  The Blaze Advisor business rules management system is used to design, develop, execute and maintain rules-based business applications. The Blaze Advisor system enables businesses to more quickly develop complex decision making applications, respond to changing customer needs, implement regulatory compliance and reduce the total cost of day-to-day operations. The Blaze Advisor system is sold as an end-user tool and is also the rules engine within several of our Strategy Machine solutions. In fiscal 2005, we introduced a software offering called SmartForms for Blaze Advisor that is used to create and manage dynamic, web-based forms that improve the completeness and accuracy of customer data collected online. In September 2005, we acquired certain assets of RulesPower, Inc. (“RulesPower”), including its advanced rules execution technology. The latest version of the Blaze Advisor system, released in fiscal 2006, is available in six languages. It is a multi-platform solution that supports Web Services and SOA, Java 2 Enterprise Edition (J2EE) platforms, Microsoft .NET and COBOL for z/OS mainframes, and is the first rules engine to support Java, .NET and COBOL deployment of the same rules. It also incorporates the exclusive Rete III rules execution technology acquired from RulesPower in fiscal 2005, which improves the efficiency and speed with which the Blaze Advisor system is able to process and execute complex, high-volume business rules.

•  Model Development.  Model Builder for Predictive Analytics enables the user to develop and deploy sophisticated predictive models for use in automated decisions. This software is based on the methodology and tools Fair Isaac uses to build both client-level and industry-level predictive models, and which we have evolved over nearly 40 years. The predictive models produced can be embedded in custom production applications or one of our Strategy Machine Solutions, and can also be executed in Blaze Advisor. The latest version of Model Builder, released in fiscal 2006, includes an optional segmentation module that can improve the quality of predictions by using Fair Isaac genetic algorithms to find segments of the data population that can benefit from specialized predictive models.

•  Data-Driven Strategy Design.  Model Builder for Decision Trees enables the user to create empirical strategies, augmenting the user’s expert judgment by applying data-driven analytics to discover patterns empirically. In designing the steps and criteria of a decision strategy, the user can segment the customer base for targeted action based on the results of different performance measures, and can simulate the performance of the designed strategy. Decision Optimizer, a key component in our Strategy Science offerings, uses an optimization algorithm to deliver customer treatment strategies or rule sets that improve results along one or more specified business objectives, while meeting stated constraints. The data-driven strategies produced by these tools can be executed by Blaze Advisor or one of our Strategy Machine Solutions.

In the United States, we market our products and services primarily through our own direct sales organization that is organized around Integrated Client Networks, or “ICNs”, which are sales teams that focus on customer segments typically aligned by vertical market and geography. Sales groups are based in our headquarters and in field offices strategically located

12

both in and outside the United States. We also market our products through indirect channels, including alliance partners and other resellers.

During fiscal 2006, 2005 and 2004, revenues generated from our agreements with Equifax, TransUnion and Experian collectively accounted for 18%, 17% and 16% of our total revenues, respectively.

Outside the United States, we market our products and services primarily through our subsidiary sales organizations. Our subsidiaries license and support our products in their local countries as well as within other foreign countries where we do not operate through a direct sales subsidiary. We also market our products through resellers and independent distributors in international territories not covered by our subsidiaries’ direct sales organizations.

Our largest market segments outside the United States are the United Kingdom and Canada. In addition, we have delivered products to users in over 60 countries.

Revenues from international customers, including end users and resellers, amounted to 28%, 25% and 22% of our total revenues in fiscal 2006, 2005 and 2004, respectively. See Note 16 to the accompanying consolidated financial statements for a summary of our operating segments and geographic information.

TECHNOLOGY

We specialize in analytics, software and data management technologies that analyze data and drive business processes and decision strategies. We maintain active research in a number of fields for the purposes of deriving greater insight and predictive value from data, making various forms of data more usable and valuable to the model-building process, and automating and applying analytics to the various processes involved in making high-volume decisions in real time.

Because of our pioneering work in credit scoring and fraud detection, we are widely recognized as the leader in predictive analytics. In addition, our Blaze Advisor software is consistently ranked as a leader in rules management systems. In all our work, we believe that our tools and processes are among the very best commercially available, and that we are uniquely able to integrate advanced analytic, software and data technologies into mission-critical business solutions that offer superior returns on investment.

Principal Areas of Expertise

Predictive Modeling.  Predictive modeling identifies and mathematically represents underlying relationships in historical data in order to explain the data and make predictions or classifications about future events. Our models summarize large quantities of data to amplify its value. Predictive models typically analyze current and historical data on individuals to produce easily understood metrics such as scores. These scores rank-order individuals by likely future performance, e.g., their likelihood of making credit payments on time, or of responding to a particular offer for services. We also include in this category models that detect the likelihood of a transaction being fraudulent. Our predictive models are frequently operationalized in mission-critical transactional systems and drive decisions and actions in near real time. A number of analytic methodologies underlie our products in this area. These include proprietary applications of both linear and non-linear mathematical programming algorithms, in which one objective is optimized within a set of constraints, and advanced “neural” systems, which learn complex patterns from large data sets to predict the probability that a new individual will exhibit certain behaviors of business interest. We also apply various related statistical techniques for analysis and pattern detection within large datasets. For example, we recently developed a proprietary technology we call “Peacock,” which can analyze large-scale purchase transaction data to reveal product relationships, purchase patterns and sequences.

Decision Analysis and Optimization.  Decision analysis refers to the broad quantitative field that deals with modeling, analyzing and optimizing decisions made by individuals, groups and organizations. Whereas predictive models analyze multiple aspects of individual behavior to forecast future behavior, decision analysis analyzes multiple aspects of a given decision to identify the most effective action to take to reach a desired result. We have developed an integrated approach to decision analysis that incorporates the development of a decision model that mathematically maps the entire decision structure; proprietary optimization technology that identifies the most

13

effective strategies, given both the performance objective and constraints; the development of designed testing required for active, continuous learning; and the robust extrapolation of an optimized strategy to a wider set of scenarios than historically encountered. This technology is behind our Strategy Science solutions.

Transaction Profiling.  Transaction profiling is a patent-protected technique used to extract meaningful information and reduce the complexity of transaction data used in modeling. Many of our products operate using transactional data, such as credit card purchase transactions, or other types of data that change over time. In its raw form, this data is very difficult to use in predictive models for several reasons: First, an isolated transaction contains very little information about the behavior of the individual that generated the transaction. In addition, transaction patterns change rapidly over time. Finally, this type of data can often be highly complex. To overcome these issues, we have developed a set of proprietary techniques that transform raw transactional data into a mathematical representation that reveals latent information, and which make the data more usable by predictive models. This profiling technology accumulates data across multiple transactions of many types to create and update profiles of transaction patterns. These profiles enable our neural network models to efficiently and effectively make accurate assessments of, for example, fraud risk and credit risk within real-time transaction streams.

Customer Data Integration.  Decisions made on customers or prospects can benefit from data stored in multiple sources, both inside and outside the enterprise. We have focused on developing data integration processes that are able to assemble and integrate those disparate data sources into a unified view of the customer or household, through the application of persistent keying technology.

Decision Management Software.  In order to make a decision strategy operational, the various steps and rules need to be programmed or exported into the business’ software infrastructure, where it can communicate with front-end, customer-facing systems and back-end systems such as billing systems. We have developed software systems, sometimes known as decision engines and business rules management systems that perform the necessary functions to execute a decision strategy. Our software includes very efficient programs for these functions, facilitating, for example, business user definition of extremely complex decision strategies using graphic user interfaces; simultaneous testing of hundreds of decision strategies in “champion/challenger” (test/control) mode; high-volume processing and analysis of transactions in real time; integration of multiple data sources; and execution of predictive models for improved behavior forecasts and finer segmentation.

Research and Development Activities

Our research and development expenses were $85.0 million, $81.3 million, and $71.1 million in fiscal 2006, 2005 and 2004, respectively. We believe that our future success depends on our ability to continually maintain and improve our core technologies, enhance our existing products, and develop new products and technologies that meet an expanding range of markets and customer requirements. In the development of new products and enhancements to existing products, we use our own development tools extensively.

We have traditionally relied primarily on the internal development of our products. Based on timing and cost considerations, however, we have acquired, and in the future may consider acquiring, technology or products from third parties.

PRODUCT PROTECTION AND TRADEMARKS

We rely on a combination of patent, copyright, trademark and trade secret laws and confidentiality agreements and procedures to protect our proprietary rights.

We retain the title to and protect the suite of models and software used to develop scoring models as a trade secret. We also restrict access to our source code and limit access to and distribution of our software, documentation and other proprietary information. We have generally relied upon the laws protecting trade secrets and upon contractual non-disclosure safeguards and restrictions on transferability to protect our software and proprietary interests in our product and service methodology and know-how. Our confidentiality procedures include invention assignment and proprietary information agreements with our employees and independent contractors, and nondisclosure agreements with our distributors, strategic partners and customers. We also claim copyright protection for certain proprietary software and documentation.

14

We have patents on many of our technologies and have patent applications pending on other technologies. The patents we hold may not be upheld as valid and may not prevent the development of competitive products. In addition, patents may never be issued on our pending patent applications or on any future applications that we may submit. We currently hold 39 U.S. and 11 foreign patents with 105 applications pending.

Despite our precautions, it may be possible for competitors or users to copy or reproduce aspects of our software or to obtain information that we regard as trade secrets. In addition, the laws of some foreign countries do not protect proprietary rights to the same extent as do the laws of the United States. Patents and other protections for our intellectual property are important, but we believe our success and growth will depend principally on such factors as the knowledge, ability, experience and creative skills of our personnel, new products, frequent product enhancements and name recognition.

We have developed technologies for research projects conducted under agreements with various United States government agencies or their subcontractors. Although we have acquired commercial rights to these technologies, the United States government typically retains ownership of intellectual property rights and licenses in the technologies that we develop under these contracts. In some cases, the United States government can terminate our rights to these technologies if we fail to commercialize them on a timely basis. In addition, under United States government contracts, the government may make the results of our research public, which could limit our competitive advantage with respect to future products based on funded research.

We have used, registered and/or applied to register certain trademarks and service marks for our technologies, products and services. We currently have 36 trademarks registered in the U.S. and select foreign countries.

PERSONNEL

As of September 30, 2006, we employed 2,737 persons worldwide. Of these, 403 full-time employees were located in our Minneapolis and Arden Hills, Minnesota offices, 351 full-time employees were located in our San Rafael, California office, 378 full-time employees were located in our San Diego, California office, and 225 full-time employees were located in our United Kingdom-based offices. None of our employees is covered by a collective bargaining agreement and no work stoppages have been experienced.

Information regarding our officers is included in “Executive Officers of the Registrant” at the end of Part I of this report.

Item 1A.  Risk Factors

RISK FACTORS

Risks Related to Our Business

We have expanded the pursuit of our EDM strategy, and we may not be successful.

We have expanded the pursuit of our business objective to become a leader in helping businesses automate and improve decisions across their enterprises, an approach that we commonly refer to as Enterprise Decision Management, or “EDM”. Our EDM strategy is designed to enable us to increase our business by selling multiple products to clients, as well as to enable the development of custom client solutions that may lead to opportunities to develop new proprietary scores or other new proprietary products. The market may be unreceptive to this general EDM business approach, including being unreceptive to purchasing multiple products from us or unreceptive to our customized solutions. If our EDM strategy is not successful, we may not be able to grow our business, growth may occur more slowly than we anticipate or our revenues and profits may decline.

We recently restructured the method by which we sell our products and services and if our new sales strategy is not successful, our business will be harmed.

Previously, we sold our products and services in a product-focused manner. As part of our expanded EDM strategy, we now sell our products and services using a client-centric approach which focuses on delivering

15

complete solutions involving multiple products or suites of products for our customers through various means, including the use of client teams called Integrated Client Networks (or “ICNs”) that focus on customers by vertical market and geography, and the use of an integrated consulting and sales approach. If our employees are not able to adjust rapidly enough to this ICN approach, then we may be unable to maintain or increase our revenues. Further, there can be no assurance that our customers and potential customers will react positively to EDM or this new selling approach and, as a result, that we will continue to maintain or increase revenues. If revenues eventually increase as a result of this change, there is no assurance that any increase will occur as quickly as we might anticipate.

We derive a substantial portion of our revenues from a small number of products and services, and if the market does not continue to accept these products and services, our revenues will decline.

As we attempt to implement our EDM strategy, we expect that revenues derived from our scoring solutions, account management solutions, fraud solutions, originations, collections, and insurance solutions products and services will continue to account for a substantial portion of our total revenues for the foreseeable future. Our revenues will decline if the market does not continue to accept these products and services. Factors that might affect the market acceptance of these products and services include the following:

•  changes in the business analytics industry;

•  changes in technology;

•  our inability to obtain or use state fee schedule or claims data in our insurance products;

•  saturation of market demand;

•  loss of key customers;

•  industry consolidation;

•  failure to execute our client-centric selling approach; and

•  inability to successfully sell our products in new vertical markets.

If we are unable to access new markets or develop new distribution channels, our business and growth prospects could suffer.

We expect that part of the growth that we seek to achieve through our EDM strategy will be derived from the sale of EDM products and service solutions in industries and markets we do not currently serve. We also expect to grow our business by delivering our EDM solutions through additional distribution channels. If we fail to penetrate these industries and markets to the degree we anticipate utilizing our EDM strategy, or if we fail to develop additional distribution channels, we may not be able to grow our business, growth may occur more slowly than we anticipate or our revenues and profits may decline.

If we are unable to develop successful new products or if we experience defects, failures and delays associated with the introduction of new products, our business could suffer serious harm.

Our growth and the success of our EDM strategy depends upon our ability to develop and sell new products or suites of products. If we are unable to develop new products, or if we are not successful in introducing new products, we may not be able to grow our business, or growth may occur more slowly than we anticipate. In addition, significant undetected errors or delays in new products or new versions of products may affect market acceptance of our products and could harm our business, financial condition or results of operations. In the past, we have experienced delays while developing and introducing new products and product enhancements, primarily due to difficulties developing models, acquiring data and adapting to particular operating environments. We have also experienced errors or “bugs” in our software products, despite testing prior to release of the products. Software errors in our products could affect the ability of our products to work with other hardware or software products, could delay the development or release of new products or new versions of products and could adversely affect market acceptance of our products. Errors or defects in our products that are significant, or are perceived to be

16

significant, could result in: rejection of our products, damage to our reputation, loss of revenues, diversion of development resources, increase in product liability claims, and increases in service and support costs and warranty claims.

We rely on relatively few customers, as well as our contracts with the three major credit reporting agencies, for a significant portion of our revenues and profits. If the terms of these relationships change, our revenues and operating results could decline.

Most of our customers are relatively large enterprises, such as banks, credit card processors, insurance companies, healthcare firms, retailers and telecommunications carriers. As a result, many of our customers and potential customers are significantly larger than we are and may have sufficient bargaining power to demand reduced prices and favorable nonstandard terms.

We also derive a substantial portion of our revenues and operating income from our contracts with the three major credit reporting agencies, TransUnion, Equifax and Experian, and other parties that distribute our products to certain markets. We are also currently involved in litigation with TransUnion, Equifax and Experian arising from their development and marketing of a credit scoring product competitive with our products. We have asserted various claims, including claims of unfair competition and antitrust, against each of the credit reporting agencies and their collective joint venture entity, VantageScore, LLC. This litigation could have a material adverse effect on our relationship with one or more of the major credit reporting agencies, or with major customers.

The loss of or a significant change in a relationship with a major customer, the loss of or a significant change in a relationship with one of the major credit reporting agencies with respect to their distribution of our products or with respect to our myFICO offerings, the loss of or a significant change in a relationship with a significant third-party distributor or the delay of significant revenues from these sources, could have a material adverse effect on our revenues and results of operations.

We rely on relationships with third parties for marketing and distribution. If we experience difficulties in these relationships, our future revenues may be adversely affected.

Our Scoring Solutions segment and Strategy Machine Solutions segment rely on distributors, and we intend to continue to market and distribute our products through existing and future distributor relationships. Our Scoring Solutions segment relies on, among others, TransUnion, Equifax and Experian. Failure of our existing and future distributors to generate significant revenues, demands by such distributors to change the terms on which they offer our products or our failure to establish additional distribution or sales and marketing alliances could have a material adverse effect on our business, operating results and financial condition. In addition, certain of our distributors presently compete with us and may compete with us in the future either by developing competitive products themselves or by distributing competitive offerings. For example, TransUnion, Equifax and Experian have developed a credit scoring product to compete directly with our products and are collectively attempting to sell the product. Competition from distributors or other sales and marketing partners could significantly harm sales of our products.

If we do not engage in acquisition activity to the extent we have in the past, we may be unable to increase our revenues at historical growth rates.

Our historical revenue growth has been augmented by numerous acquisitions, and we anticipate that acquisitions will continue to be an important part of our revenue growth. Our future revenue growth rate may decline if we do not make acquisitions of similar size and at a comparable rate as in the past.

17

If we engage in acquisitions, significant investments in new businesses, or divestitures of existing businesses, we will incur a variety of risks, any of which may adversely affect our business.

We have made in the past, and may make in the future, acquisitions of, or significant investments in, businesses that offer complementary products, services and technologies. Any acquisitions or investments will be accompanied by the risks commonly encountered in acquisitions of businesses, which may include:

•  failure to achieve the financial and strategic goals for the acquired and combined business;

•  overpayment for the acquired companies or assets;

•  difficulty assimilating the operations and personnel of the acquired businesses;

•  product liability exposure associated with acquired businesses or the sale of their products;

•  disruption of our ongoing business;

•  dilution of our existing stockholders and earnings per share;

•  unanticipated liabilities, legal risks and costs;

•  retention of key personnel;

•  distraction of management from our ongoing business; and

•  impairment of relationships with employees and customers as a result of integration of new management personnel.

We have also divested ourselves of businesses in the past, and may do so again in the future. Any divestitures will be accompanied by the risks commonly encountered in the sale of businesses, which may include:

•  disruption of our ongoing business;

•  dilution of our existing stockholders and earnings per share;

•  unanticipated liabilities, legal risks and costs;

•  retention of key personnel;

•  distraction of management from our ongoing business; and

•  impairment of relationships with employees and customers as a result of migrating a business to new owners.

These risks could harm our business, financial condition or results of operations, particularly if they occur in the context of a significant acquisition. Acquisitions of businesses having a significant presence outside the U.S. will increase our exposure to the risks of conducting operations in international markets.

The occurrence of certain negative events may cause fluctuations in our stock price.

The market price of our common stock may be volatile and could be subject to wide fluctuations due to a number of factors, including variations in our revenues and operating results. We believe that you should not rely on period-to-period comparisons of financial results as an indication of future performance. Because many of our operating expenses are fixed and will not be affected by short-term fluctuations in revenues, short-term fluctuations in revenues may significantly impact operating results. Additional factors that may cause our stock price to fluctuate include the following:

•  variability in demand from our existing customers;

•  failure to meet the expectations of market analysts;

•  changes in recommendations by market analysts;

•  the lengthy and variable sales cycle of many products, combined with the relatively large size of orders for our products, increases the likelihood of short-term fluctuation in revenues;

18

•  consumer dissatisfaction with, or problems caused by, the performance of our products;

•  the timing of new product announcements and introductions in comparison with our competitors;

•  the level of our operating expenses;

•  changes in competitive conditions in the consumer credit, financial services and insurance industries;

•  fluctuations in domestic and international economic conditions;

•  our ability to complete large installations on schedule and within budget;

•  acquisition-related expenses and charges; and

•  timing of orders for and deliveries of software systems.

In addition, the financial markets have experienced significant price and volume fluctuations that have particularly affected the stock prices of many technology companies, and these fluctuations sometimes have been unrelated to the operating performance of these companies. Broad market fluctuations, as well as industry-specific and general economic conditions may adversely affect the market price of our common stock.

Our products have long and variable sales cycles. If we do not accurately predict these cycles, we may not forecast our financial results accurately and our stock price could be adversely affected.

We experience difficulty in forecasting our revenues accurately because the length of our sales cycles makes it difficult for us to predict the quarter in which sales will occur. In addition, our ICN selling approach is more complex than our prior sales approach because it emphasizes the sale of complete EDM solutions involving multiple products or services across our customers’ organizations. This also makes forecasting of revenues in any given period more difficult. As a result of our ICN approach and lengthening sales cycles, revenues and operating results may vary significantly from period to period. For example, the sales cycle for licensing our products typically ranges from 60 days to 18 months. Customers are often cautious in making decisions to acquire our products, because purchasing our products typically involves a significant commitment of capital, and may involve shifts by the customer to a new software and/or hardware platform or changes in the customer’s operational procedures. Since our EDM strategy contemplates the sale of multiple decision solutions to a customer, expenditures by any given customer may be larger than with our prior sales approach. This may cause customers to make purchasing decisions more cautiously. Delays in completing sales can arise while customers complete their internal procedures to approve large capital expenditures and test and accept our applications. Consequently, we face difficulty predicting the quarter in which sales to expected customers will occur and experience fluctuations in our revenues and operating results. If we are unable to accurately forecast our revenues, our stock price could be adversely affected.

We typically have revenue-generating transactions concentrated in the final weeks of a quarter which may prevent accurate forecasting of our financial results and cause our stock price to decline.

Large portions of our software license agreements are consummated in the weeks immediately preceding quarter end. Before these agreements are consummated we create and rely on forecasted revenues for planning, modeling and earnings guidance. Forecasts, however, are only estimates and actual results may vary for a particular quarter or longer periods of time. Consequently, significant discrepancies between actual and forecasted results could limit our ability to plan, budget or provide accurate guidance, which could adversely affect our stock price. Any publicly-stated revenue or earnings projections are subject to this risk.

The failure to recruit and retain additional qualified personnel could hinder our ability to successfully manage our business.

Our EDM strategy and our future success will depend in large part on our ability to attract and retain experienced sales, consulting, research and development, marketing, technical support and management personnel. The complexity of our products requires highly trained customer service and technical support personnel to assist customers with product installation and deployment. The labor market for these individuals is very competitive due

19

to the limited number of people available with the necessary technical skills and understanding and may become more competitive with general market and economic improvement. We cannot be certain that our compensation strategies will be perceived as competitive by current or prospective employees. This could impair our ability to recruit and retain personnel. We have experienced difficulty in recruiting qualified personnel, especially technical, sales and consulting personnel, and we may need additional staff to support new customers and/or increased customer needs. We may also recruit skilled technical professionals from other countries to work in the United States. Limitations imposed by immigration laws in the United States and abroad and the availability of visas in the countries where we do business could hinder our ability to attract necessary qualified personnel and harm our business and future operating results. There is a risk that even if we invest significant resources in attempting to attract, train and retain qualified personnel, we will not succeed in our efforts, and our business could be harmed. Non-appreciation in the value of our stock may adversely affect our ability to use equity and equity based incentive plans to attract and retain personnel, and may require us to use alternative and more expensive forms of compensation for this purpose.

The failure to obtain certain forms of model construction data from our customers or others could harm our business.

We must develop or obtain a reliable source of sufficient amounts of current and statistically relevant data to analyze transactions and update our products. In most cases, these data must be periodically updated and refreshed to enable our products to continue to work effectively in a changing environment. We do not own or control much of the data that we require, most of which is collected privately and maintained in proprietary databases. Customers and key business alliances provide us the data we require to analyze transactions, report results and build new models. Our EDM strategy depends in part upon our ability to access new forms of data to develop custom and proprietary analytic tools. If we fail to maintain sufficient sourcing relationships with our customers and business alliances, or if they decline to provide such data due to legal privacy concerns, competition concerns, prohibitions or a lack of permission from their customers, we could lose access to required data and our products might become less effective. In addition, certain of our insurance solutions products use data from state workers’ compensation fee schedules adopted by state regulatory agencies. Third parties have asserted copyright interests in these data, and these assertions, if successful, could prevent us from using these data. Any interruption of our supply of data could seriously harm our business, financial condition or results of operations.

We will continue to rely upon proprietary technology rights, and if we are unable to protect them, our business could be harmed.

Our success depends, in part, upon our proprietary technology and other intellectual property rights. To date, we have relied primarily on a combination of copyright, patent, trade secret, and trademark laws, and nondisclosure and other contractual restrictions on copying and distribution to protect our proprietary technology. This protection of our proprietary technology is limited, and our proprietary technology could be used by others without our consent. In addition, patents may not be issued with respect to our pending or future patent applications, and our patents may not be upheld as valid or may not prevent the development of competitive products. Any disclosure, loss, invalidity of, or failure to protect our intellectual property could negatively impact our competitive position, and ultimately, our business. There can be no assurance that our protection of our intellectual property rights in the United States or abroad will be adequate or that others, including our competitors, will not use our proprietary technology without our consent. Furthermore, litigation may be necessary to enforce our intellectual property rights, to protect our trade secrets, or to determine the validity and scope of the proprietary rights of others. Such litigation could result in substantial costs and diversion of resources and could harm our business, financial condition or results of operations.

Some of our technologies were developed under research projects conducted under agreements with various U.S. government agencies or subcontractors. Although we have commercial rights to these technologies, the U.S. government typically retains ownership of intellectual property rights and licenses in the technologies developed by us under these contracts, and in some cases can terminate our rights in these technologies if we fail to commercialize them on a timely basis. Under these contracts with the U.S. government, the results of research may

20

be made public by the government, limiting our competitive advantage with respect to future products based on our research.

If we are subject to infringement claims, it could harm our business.

With recent developments in the law that permit patenting of business methods, we expect that products in the industry segments in which we compete, including software products, will increasingly be subject to claims of patent infringement as the number of products and competitors in our industry segments grow. We may need to defend claims that our products infringe patent, copyright or other rights, and as a result we may:

•  incur significant defense costs or substantial damages;

•  be required to cease the use or sale of infringing products;

•  expend significant resources to develop or license a substitute non-infringing technology;

•  discontinue the use of some technology; or

•  be required to obtain a license under the intellectual property rights of the third party claiming infringement, which license may not be available or might require substantial royalties or license fees that would reduce our margins.

Breaches of security, or the perception that e-commerce is not secure, could harm our business.

Our business requires the appropriate and secure utilization of consumer and other sensitive information. Internet-based, electronic commerce requires the secure transmission of confidential information over public networks, and several of our products are accessed through the Internet, including our consumer services accessible through the www.myFICO.com website. Security breaches in connection with the delivery of our products and services, including products and services utilizing the Internet, or well-publicized security breaches, and the trend toward broad consumer and general public notification of such incidents, could significantly harm our business, financial condition or results of operations. We cannot be certain that advances in criminal capabilities, discovery of new vulnerabilities, attempts to exploit vulnerabilities in our systems, data thefts, physical system or network break-ins or inappropriate access, or other developments will not compromise or breach the technology protecting the networks that access our net-sourced products, consumer services and proprietary database information.

Protection from system interruptions is important to our business. If we experience a sustained interruption of our telecommunication systems it could harm our business.

Systems or network interruptions could delay and disrupt our ability to develop, deliver or maintain our products and services, causing harm to our business and reputation and resulting in loss of customers or revenue. These interruptions can include fires, floods, earthquakes, power losses, equipment failures and other events beyond our control.

Risks Related to Our Industry

Our ability to increase our revenues will depend to some extent upon introducing new products and services. If the marketplace does not accept these new products and services, our revenues may decline.

We have a significant share of the available market in portions of our Scoring Solutions segment and for certain services in our Strategy Machine Solutions segment, specifically, the markets for account management services at credit card processors and credit card fraud detection software. To increase our revenues, we must enhance and improve existing products and continue to introduce new products and new versions of existing products that keep pace with technological developments, satisfy increasingly sophisticated customer requirements and achieve market acceptance. We believe much of the future growth of our business and the success of our EDM strategy will rest on our ability to continue to expand into newer markets for our products and services, such as direct marketing, healthcare, insurance, small business lending, retail, telecommunications, personal credit management, the design of business strategies using Strategy Science technology and Internet services. These areas are relatively new to our product development and sales and marketing personnel. Products that we plan to market in the future are in various

21

stages of development. We cannot assure you that the marketplace will accept these products. If our current or potential customers are not willing to switch to or adopt our new products and services, our revenues will decrease.

If we fail to keep up with rapidly changing technologies, our products could become less competitive or obsolete.

In our markets, technology changes rapidly, and there are continuous improvements in computer hardware, network operating systems, programming tools, programming languages, operating systems, database technology and the use of the Internet. If we fail to enhance our current products and develop new products in response to changes in technology or industry standards, or if we fail to bring product enhancements or new product developments to market quickly enough, our products could rapidly become less competitive or obsolete. For example, the rapid growth of the Internet environment creates new opportunities, risks and uncertainties for businesses, such as ours, which develop software that must also be designed to operate in Internet, intranet and other online environments. Our future success will depend, in part, upon our ability to:

•  innovate by internally developing new and competitive technologies;

•  use leading third-party technologies effectively;

•  continue to develop our technical expertise;

•  anticipate and effectively respond to changing customer needs;

•  initiate new product introductions in a way that minimizes the impact of customers delaying purchases of existing products in anticipation of new product releases; and

•  influence and respond to emerging industry standards and other technological changes.

If our competitors introduce new products and pricing strategies, it could decrease our product sales and market share, or could pressure us to reduce our product prices in a manner that reduces our margins.

We may not be able to compete successfully against our competitors, and this inability could impair our capacity to sell our products. The market for business analytics is new, rapidly evolving and highly competitive, and we expect competition in this market to persist and intensify. Our regional and global competitors vary in size and in the scope of the products and services they offer, and include:

•  in-house analytic and systems developers;

•  scoring model builders;

•  enterprise resource planning (ERP) and customer relationship management (CRM) packaged solutions providers;

•  business intelligence solutions providers;

•  credit report and credit score providers;

•  business process management solution providers;

•  process modeling tools providers;

•  automated application processing services providers;

•  data vendors;

•  neural network developers and artificial intelligence system builders;

•  third-party professional services and consulting organizations;

•  account/workflow management software providers;

22

•  managed care organizations; and

•  software tools companies supplying modeling, rules, or analytic development tools.

We expect to experience additional competition from other established and emerging companies, as well as from other technologies. For example, certain of our fraud solutions products compete against other methods of preventing credit card fraud, such as credit cards that contain the cardholder’s photograph, smart cards, cardholder verification and authentication solutions and other card authorization techniques. Many of our anticipated competitors have greater financial, technical, marketing, professional services and other resources than we do and industry consolidation is creating even larger competitors in many of our markets. As a result, our competitors may be able to respond more quickly to new or emerging technologies and changes in customer requirements. They may also be able to devote greater resources than we can to develop, promote and sell their products. Many of these companies have extensive customer relationships, including relationships with many of our current and potential customers. Furthermore, new competitors or alliances among competitors may emerge and rapidly gain significant market share. For example, TransUnion, Equifax and Experian have formed an alliance that has developed a credit scoring product competitive with our products. If we are unable to respond as quickly or effectively to changes in customer requirements as our competition, our ability to expand our business and sell our products will be negatively affected.

Our competitors may be able to sell products competitive to ours at lower prices individually or as part of integrated suites of several related products. This ability may cause our customers to purchase products that directly compete with our products from our competitors. Price reductions by our competitors could negatively impact our margins, and could also harm our ability to obtain new long-term contracts and renewals of existing long-term contracts on favorable terms.

Government regulations that apply to us or to our customers may expose us to liability, affect our ability to compete in certain markets, limit the profitability of or demand for our products, or render our products obsolete. If these regulations are applied or are further developed in ways adverse to us, it could adversely affect our business and results of operations.

Legislation and governmental regulation affect how our business is conducted and, in some cases, subject us to the possibility of future lawsuits arising from our products and services. Globally, legislation and governmental regulation also influence our current and prospective customers’ activities, as well as their expectations and needs in relation to our products and services. Both our core businesses and our newer initiatives are affected globally by federal, regional, provincial, state and other jurisdictional regulations, including those in the following significant regulatory areas:

•  Consumer report data and consumer reporting agencies. Examples in the U.S. include: the Fair Credit Reporting Act (“FCRA”), the Fair and Accurate Credit Transactions Act (“FACTA”), which amends FCRA, and certain proposed regulations under FACTA, presently under consideration;

•  Identity theft and loss of data. Examples include FACTA and other regulations modeled after the current California Security Breach Notification Act, that require consumer notification of security breach incidents and additional federal and state legislative enactments in this area;

•  Fair and non-discriminatory lending practices, such as the Equal Credit Opportunity Act (“ECOA”);

•  Privacy-related laws, including but not limited to the provisions of the Financial Services Modernization Act of 1999, also known as the Gramm Leach Bliley Act (“GLBA”), the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (“USA Patriot Act”) and similar state privacy laws;

•  Extension of credit to consumers through the Electronic Fund Transfers Act, as well as non-governmental VISA and MasterCard electronic payment standards;

•  Quasi-governmental regulations, such as Fannie Mae and Freddie Mac regulations for our mortgage services products;

23

•  Insurance regulations related to our insurance products;

•  The application or extension of consumer protection laws, including, state and federal laws governing the use of the Internet and telemarketing, and credit repair;

•  Jurisdictional regulations applicable to international operations, including the European Union’s Privacy Directive; and

•  Sarbanes-Oxley Act (“SOX”) regulations to verify internal process controls and require material event awareness and notification.

In making credit evaluations of consumers, performing fraud screening or user authentication, our customers are subject to requirements of multiple jurisdictions which may impose contradictory requirements. Privacy legislation such as GLBA or the European Union’s Privacy Directive may also affect the nature and extent of the products or services that we can provide to customers, as well as our ability to collect, monitor and disseminate information subject to privacy protection. In addition to existing regulation, changes in legislative, judicial, regulatory or consumer environments could harm our business, financial condition or results of operations. For example, the FACTA amendments to FCRA will result in new regulation. These regulations or the interpretation of these amendments could affect the demand for or profitability of some of our products, including scoring and consumer products. New regulations pertaining to financial institutions could cause them to pursue new strategies, reducing the demand for our products. In addition, legislative reforms of workers’ compensation laws that aim to simplify this area of regulation and curb abuses could diminish the need for, and the benefits provided by, certain of our insurance solutions products and services.

Our revenues depend, to a great extent, upon conditions in the consumer credit, financial services and insurance industries. If any of our clients’ industries experiences a downturn, it could harm our business, financial condition or results of operations.

During fiscal 2006, 71% of our revenues were derived from sales of products and services to the consumer credit, financial services and insurance industries. A downturn in the consumer credit, the financial services or the insurance industry, including a downturn caused by increases in interest rates or a tightening of credit, among other factors, could harm our business, financial condition or results of operations. While the rate of account growth in the U.S. bankcard industry has been slowing and many of our large institutional customers have merged and consolidated in recent years, we have generated most of our revenue growth from our bankcard-related scoring and account management businesses by selling and cross-selling our products and services to large banks and other credit issuers. As this industry continues to consolidate, we may have fewer opportunities for revenue growth due to changing demand for our products and services that support customer acquisition programs of our customers. In addition, industry consolidation could affect the base of recurring revenues derived from contracts in which we are paid on a per-transaction basis if consolidated customers combine their operations under one contract. There can be no assurance that we will be able effectively to promote future revenue growth in our businesses.

While we are expanding our sales of consumer credit, financial services and insurance products and services into international markets, the risks are greater as we are less well-known and some of these markets are in their infancy.

Risk Related to External Conditions

If any of a number of material adverse developments occurs in general economic conditions and world events, such developments could affect demand for our products and services and harm our business.

Purchases of technology products and services and decisioning solutions are subject to adverse economic conditions. When an economy is struggling, companies in many industries delay or reduce technology purchases, and we experience softened demand for our decisioning solutions and other products and services. If the current improvement in global economic conditions slows or reverses, or if there is an escalation in regional or continued global conflicts or terrorism, we may experience reductions in capital expenditures by our customers, longer sales cycles, deferral or delay of purchase commitments for our products and increased price competition, which may adversely affect our business and results of operations.

24

In operations outside the United States, we are subject to unique risks that may harm our business, financial condition or results of operations.

A growing portion of our revenues is derived from international sales. During fiscal 2006 28% of our revenues were derived from business outside the United States. As part of our growth strategy, we plan to continue to pursue opportunities outside the United States, including opportunities in countries with economic systems that are in early stages of development and that may not mature sufficiently to yield growth for our business. Accordingly, our future operating results could be negatively affected by a variety of factors arising out of international commerce, some of which are beyond our control. These factors include:

•  general economic and political conditions in countries where we sell our products and services;

•  difficulty in staffing and efficiently managing our operations in multiple geographic locations and in various countries;

•  effects of a variety of foreign laws and regulations, including restrictions on access to personal information;

•  import and export licensing requirements;

•  longer payment cycles;

•  reduced protection for intellectual property rights;

•  currency fluctuations;

•  changes in tariffs and other trade barriers; and

•  difficulties and delays in translating products and related documentation into foreign languages.

There can be no assurance that we will be able to successfully address each of these challenges in the near term. Additionally, some of our business will be conducted in currencies other than the U.S. dollar. Foreign currency transaction gains and losses are not currently material to our cash flows, financial position or results of operations. However, an increase in our foreign revenues could subject us to increased foreign currency transaction risks in the future.

In addition to the risk of depending on international sales, we have risks incurred in having research and development personnel located in various international locations. We currently have approximately 20% of our product development staff in international locations, some of which have political and developmental risks. If such risks materialize, our business could be damaged.

Our anti-takeover defenses could make it difficult for another company to acquire control of Fair Isaac, thereby limiting the demand for our securities by certain types of purchasers or the price investors are willing to pay for our stock.

Certain provisions of our Restated Certificate of Incorporation, as amended, could make a merger, tender offer or proxy contest involving us difficult, even if such events would be beneficial to the interests of our stockholders. These provisions include adopting a Shareholder Rights Agreement, commonly known as a “poison pill,” and giving our board the ability to issue preferred stock and determine the rights and designations of the preferred stock at any time without stockholder approval. The rights of the holders of our common stock will be subject to, and may be adversely affected by, the rights of the holders of any preferred stock that may be issued in the future. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or discouraging a third party from acquiring, a majority of our outstanding voting stock. These factors and certain provisions of the Delaware General Corporation Law may have the effect of deterring hostile takeovers or otherwise delaying or preventing changes in control or changes in our management, including transactions in which our stockholders might otherwise receive a premium over the fair market value of our common stock.

25

If we experience changes in tax laws or adverse outcomes resulting from examination of our income tax returns, it could adversely affect our results of operations.

We are subject to federal and state income taxes in the United States and in certain foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. Our future effective tax rates could be adversely affected by changes in tax laws, by our ability to generate taxable income in foreign jurisdictions in order to utilize foreign tax losses, and by the valuation of our deferred tax assets. In addition, we are subject to the examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from such examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from such examinations will not have an adverse effect on our operating results and financial condition.

Item 3.   Legal Proceedings

We are a defendant in a lawsuit captioned as Robbie Hillis v. Equifax Consumer Services, Inc. and Fair Isaac, Inc., which is pending in the U.S. District Court for the Northern District of Georgia. The plaintiff claims that the defendants have jointly sold the Score Power^® credit score product in violation of certain procedural requirements under the Credit Repair Organizations Act (“CROA”), and in violation of the antifraud provisions of that statute. The plaintiff also claims that the defendants are “credit repair organizations” under CROA. The plaintiff is seeking certification of a class on behalf of all individuals who purchased products containing Score Power from the defendants in the five year period prior to the filing of the Complaint on November 14, 2004. The plaintiff is seeking unspecified damages, attorneys’ fees and costs. We believe that the claims in this lawsuit are without merit, and we have denied any liability or wrongdoing and have denied that class certification is appropriate. We are vigorously contesting this matter. The plaintiff brought a motion for class certification and a motion for summary judgment in his favor and against the defendants. We opposed, and the Court denied, both of the plaintiff’s motions. The plaintiff has brought a motion asking the Court to reconsider its prior ruling. That motion is pending.

26

We are a defendant in a lawsuit captioned as Christy Slack v. Fair Isaac Corporation and MyFICO Consumer Services, Inc., which is pending in the United States District Court for the Northern District of California. As in the Hillis matter, the plaintiff is claiming that the defendants violated certain procedural requirements of CROA, and violated the antifraud provisions of CROA, with respect to the sale of credit score products on our myFICO.com website. The plaintiff also claims that the defendants violated the California Credit Services Act (the “CSA”) and were unjustly enriched. The plaintiff has sought certification of a class on behalf of all individuals who purchased credit score products from us on the myFICO.com website in the five year period prior to the filing of the Complaint on January 18, 2005. Plaintiff seeks unspecified damages, attorneys’ fees and costs. We believe that the claims in this lawsuit are without merit and we have denied any liability or wrongdoing and have denied that class certification is appropriate. We are vigorously contesting this matter. We brought a motion to dismiss the plaintiff’s claims. The Court granted our motion, in part, by dismissing certain of the plaintiff’s claims under the CSA. The plaintiff has brought motions for summary judgment and for class certification. We have opposed both motions. The Court has not yet ruled on the plaintiff’s motions

Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operations

RESULTS OF OPERATIONS

Overview

We are a leader in Enterprise Decision Management (“EDM”) solutions that enable businesses to automate and improve their decisions across the enterprise. Our predictive analytics and decision management systems power hundreds of billions of customer decisions each year. We help companies acquire customers more efficiently, increase customer value, reduce fraud and credit losses, lower operating expenses and enter new markets more profitably. Most leading banks and credit card issuers rely on our solutions, as do many insurers, retailers, telecommunications providers, healthcare organizations, pharmaceutical and government agencies. We also serve consumers through online services that enable people to purchase and understand their FICO^® scores, the standard measure in the United States of credit risk, empowering them to manage their financial health.

Most of our revenues are derived from the sale of products and services within the consumer credit, financial services and insurance industries, and during the year ended September 30, 2006, 71% of our revenues were derived from within these industries. A significant portion of our remaining revenues is derived from the telecommunications, healthcare and retail industries, as well as the government sector. Our clients utilize our products and services to facilitate a variety of business processes, including customer marketing and acquisition, account origination, credit and underwriting risk management, fraud loss prevention and control, and client account and policyholder management. A significant portion of our revenues is derived from transactional or unit-based software license fees, annual license fees under long-term software license arrangements, transactional fees derived under scoring, network service or internal hosted software arrangements, and annual software maintenance fees. The recurrence of these revenues is, to a significant degree, dependent upon our clients’ continued usage of our products and services in their business activities. The more significant activities underlying the use of our products in these areas include: credit and debit card usage or active account levels; lending acquisition, origination and customer management activity; workers’ compensation and automobile medical injury insurance claims; and wireless and wireline calls and subscriber levels. Approximately 75% of our revenues during fiscal 2006 were derived from arrangements with transactional or unit-based pricing. We also derive revenues from other sources which generally do not recur and include, but are not limited to, perpetual or time-based licenses with upfront payment terms, non-recurring professional service arrangements and gain-share arrangements where revenue is derived based on percentages of client revenue growth or cost reductions attributable to our products.

Within a number of our sectors there has been a sizable amount of industry consolidation. In addition, many of our sectors are experiencing increased levels of competition. As a result of these factors, we believe that future revenues in particular sectors may decline. However, due to the long-term customer arrangements we have with many of our customers, the near term impact of these declines may be more limited in certain sectors.

One measure used by management as an indicator of our business performance is the volume of new bookings achieved. We define a “new booking” as estimated future contractual revenues, including agreements with perpetual, multi-year and annual terms. New bookings values may include: (i) estimates of variable fee components such as hours to be incurred under new professional services arrangements and customer account or transaction activity for agreements with transactional-based fee arrangements, (ii) additional or expanded business from renewals of contracts, and (iii) to a lesser extent, previous customers that have attrited and been re-sold only as a result of a significant sales effort. In the fourth quarter of fiscal 2006, we achieved new bookings of $112.6 million, including nine deals with bookings values of $3.0 million or more. In comparison, new bookings in the fourth quarter of fiscal 2005 were $109.7 million, including four deals with bookings values of $3.0 million or more.

Management regards the volume of new bookings achieved, among other factors, as an important indicator of future revenues, but they are not comparable to, nor should they be substituted for, an analysis of our revenues, and they are subject to a number of risks and uncertainties, including those described in Item 1A “Risk Factors”, above, concerning timing and contingencies affecting product delivery and performance. Although many of our contracts have fixed non-cancelable terms, some of our contracts are terminable by the client on short notice or without

33

notice. Accordingly, we do not believe it is appropriate to characterize all of our new bookings as backlog that will generate future revenue.

Our revenues derived from clients outside the United States continue to grow, and may in the future grow more rapidly than our revenues from domestic clients. International revenues totaled $230.2 million, $201.5 million and $152.5 million in fiscal 2006, 2005 and 2004, respectively, representing 28%, 25% and 22% of total consolidated revenues in each of these years. In addition to clients acquired via our acquisitions, we believe that our international growth is a product of successful relationships with third parties that assist in international sales efforts and our own increased sales focus internationally, and we expect that the percentage of our revenues derived from international clients will increase in the future.

We acquired London Bridge in May 2004, Braun in November 2004 and RulesPower in September 2005. Results of operations from these acquisitions are included prospectively from the date of acquisition. As a result of these acquisitions, our financial results during the year ended September 30, 2006, are not directly comparable to those during the years ended September 30, 2005 and 2004, or other years prior to any of these acquisitions.

Our reportable segments are: Strategy Machine Solutions, Scoring Solutions, Professional Services and Analytic Software Tools. Although we sell solutions and services into a large number of end user product and industry markets and have recently developed a more customer-centric focus, our reportable business segments reflect the primary method in which management organizes and evaluates internal financial information to make operating decisions and assess performance. Comparative segment revenues, operating income, and related financial information for the years ended September 30, 2006, 2005 and 2004 are set forth in Note 16 to the accompanying consolidated financial statements.

Fiscal 2006 Revenues Compared to Fiscal 2005 Revenues

Strategy Machine Solutions segment revenues increased $3.5 million due to a $12.9 million increase in revenues from our fraud solutions, a $8.9 million increase in revenues from our consumer solutions, a $5.2 million increase in revenues from our collections and recovery solutions, and a $2.2 million increase in revenues from our other strategy machine solutions, partially offset by a $16.5 million decrease in revenues from our marketing solutions and a $9.2 million decrease in revenues from our insurance and healthcare solutions. The increase in fraud solutions revenues was attributable to an increase in license sales and an increase in transaction volumes. The increase in consumer solutions revenues was partially attributable to increases in revenues derived from myFICO.com and our strategic alliance partners. The increase in consumer solutions revenues was also the result of a revision made during fiscal 2006 to the estimated period during which revenue is earned on sales of certain products that provide consumers access to multiple credit scores. The revision, which increased revenues by $1.6 million in fiscal 2006, resulted from the completion of a study that showed that consumers were accessing their scores over a shorter period of time than initially estimated. The increase in collections and recovery solutions revenues was attributable primarily to an increase in perpetual license sales revenues. This increase was driven by higher international license sales due to increased sales efforts. The decrease in marketing solutions revenues was attributable primarily to the loss of two large financial services customers during fiscal 2005, which resulted from industry consolidation. The decrease in insurance and healthcare solutions revenues was attributable primarily to the loss of several customer accounts that primarily occurred in fiscal 2005.

Scoring Solutions segment revenues increased $9.9 million primarily due to an increase in revenues derived from risk scoring services at the credit reporting agencies, resulting from increased sales of scores for prescreening activities, and an increase in revenues derived from our own prescreening services directly to users. We also achieved increased revenues from our FICO expansion score product, which provides scores on U.S. consumers who do not have traditional FICO scores because they do not have credit accounts being reported to the credit reporting agencies.

During fiscal 2006 and 2005, revenues generated from our agreements with Equifax, TransUnion and Experian, collectively accounted for approximately 18% and 17%, respectively, of our total revenues, including revenues from these customers that are recorded in our other segments.

Professional Services segment revenues increased $15.6 million from industry consulting services, implementation services for our Blaze Advisor products and predictive modeling services. The increase in industry consulting services revenue resulted from initiatives to expand our professional service offerings into additional industry markets.

Analytic Software Tools segment revenues decreased $2.3 million primarily due to a decline in sales of perpetual licenses of Blaze Advisor. This decline reflects the timing of Blaze Advisor sales, which includes large individual contracts. The decline in revenues was partially offset by higher maintenance revenues, which resulted from the overall growth in our installed base of Blaze Advisor, and an increase in sales of Model Builder software applications.

Fiscal 2005 Revenues Compared to Fiscal 2004 Revenues

The increase in total revenues from fiscal 2004 to fiscal 2005 included a $67.4 million increase in revenues that resulted from our acquisitions in fiscal 2005 and 2004.

Strategy Machine Solutions segment revenues increased due to a $21.5 million increase in revenues from our collection and recovery solutions, a $16.6 million increase in revenues from our fraud solutions, a $14.4 million increase in revenues from our mortgage banking solutions, a $7.9 million increase in revenues from our consumer solutions and a $2.2 million increase in revenues from our other strategy machine solutions, partially offset by a $21.9 million decrease in revenues from our marketing solutions and a $14.6 million decrease in revenues from our insurance and healthcare solutions. The increase in collections and recovery solutions revenues was attributable primarily to increases in license and maintenance revenues related to acquired London Bridge solutions. The increase in fraud solutions revenues was attributable to an increase in active accounts and merchant transaction volumes with our existing customer base, and to the cross-selling of additional fraud products. The increase in

35

mortgage banking solutions revenues was attributable to volumes associated with acquired London Bridge transactional-based agreements. The increase in consumer solutions revenues was attributable primarily to increases in revenues derived from myFICO.com and our strategic alliance partners due to increased customer volumes and higher average selling prices. The decrease in marketing solutions revenues was attributable primarily to the loss of two large financial services customers, which resulted from industry consolidation. The decrease in insurance and healthcare solutions revenues was attributable primarily to a decline in bill review volumes associated with our existing customer base, lower claims volumes at some of our key customers and loss of several customer accounts.

Scoring Solutions segment revenues increased primarily due to an increase in revenues derived from risk scoring services at the credit reporting agencies, resulting from increased sales of scores for prescreening activities, and an increase in revenues derived from our own prescreening services.

During fiscal 2005 and 2004, revenues generated from our agreements with Equifax, TransUnion and Experian, collectively accounted for approximately 17% and 16%, respectively, of our total revenues, including revenues from these customers that are recorded in our other segments.

Professional Services segment revenues increased $29.2 million due to an increase in implementation and precision marketing service revenues from our acquisitions of London Bridge and Braun, and a net increase of $3.8 million in revenues in various other professional service activities.

Analytic Software Tools segment revenues increased primarily due to an increase in sales of perpetual licenses of Blaze Advisor and Model Builder software applications.

Effective October 1, 2005, we adopted Statement of Financial Accounting Standards (“SFAS”) No. 123(R), Share-Based Payment, using the modified prospective transition method. Under this method, share-based compensation expense that we recognized in fiscal 2006 included expense associated with the fair value of all awards granted on and after October 1, 2005, and expense for the unvested portion of previously granted awards outstanding on October 1, 2005. The fair value of the unvested options outstanding as of October 1, 2005 was based on the fair value estimated on the grant date in accordance with the original provisions of SFAS No. 123. Results for prior periods have not been restated.

In accordance with SFAS No. 123(R), we recorded pre-tax share-based compensation expense of $42.1 million in fiscal 2006. In comparison, we recorded pre-tax share-based compensation expense of $2.9 million and $1.6 million during fiscal 2005 and 2004, respectively. Share-based compensation expense was recorded in cost of revenues, research and development, and selling, general and administrative expense.

Cost of Revenues

Cost of revenues consists primarily of employee salaries and benefits for personnel directly involved in creating, installing and supporting revenue products; travel and related overhead costs; costs of computer service bureaus; internal network hosting costs; amounts payable to credit reporting agencies for scores; software costs; and expenses related to our consumer score services through myFICO.com.

The fiscal 2006 over 2005 increase of $6.9 million in cost of revenues resulted from a $15.5 million increase in personnel and other labor-related costs, a $2.6 million increase in travel expenses and a $0.6 million increase in other costs. The increase was partially offset by an $8.4 million decrease in facilities and infrastructure costs and a $3.4 million decrease in third-party software and data costs. The increase in personnel and other labor-related costs was attributable partially to a $10.3 million increase in share-based compensation expense due to the adoption of SFAS No. 123(R) and the remaining $5.2 million increase was primarily due to higher outside consultant costs. The increase in travel costs reflects the increase in professional service projects in the current year and associated travel to client locations. The decrease in facilities and infrastructure costs was attributable primarily to a reduction in

37

depreciation expense, lower outside costs for information systems and because fiscal 2005 included system integration costs associated with our acquisition of London Bridge. The decline in third-party software and data costs was attributable to a decrease in insurance and healthcare solutions costs, which was a result of lower revenues for these products.

The fiscal 2005 over 2004 increase of $22.5 million in cost of revenues includes a $10.6 million increase in personnel and other labor-related costs, a $5.4 million increase in third-party software and data, a $4.9 million increase in facilities and infrastructure costs, and a $1.6 million net increase in various other expenditures. The increase in personnel and other labor-related costs was attributable primarily to an increase in personnel resulting from our London Bridge and Braun acquisitions. The increase in third-party software and data costs was attributable primarily to an increase in consumer solutions revenues, partially offset by a decrease in insurance and healthcare solutions revenues, and the resulting variable cost impacts. The increase in facilities and infrastructure costs was also attributable primarily to our London Bridge and Braun acquisitions.

In fiscal 2007, we expect that cost of revenues as a percentage of revenues will be consistent with, or slightly lower than, the cost of revenues incurred during fiscal 2006.

Research and Development

Research and development expenses include the personnel and related overhead costs incurred in development of new products and services, including primarily the research of mathematical and statistical models and the development of new versions of Strategy Machine Solutions and Analytic Software Tools.

The fiscal 2006 over 2005 increase of $3.7 million in research and development expenditures was partially attributable to an increase in personnel and related costs of $2.4 million, which was driven by a $6.3 million increase in share-based compensation expense due to the adoption of SFAS No. 123(R). The increase in personnel costs was partially offset by lower salary and benefit costs due to staff reductions and the shift of employees to non-U.S. locations. The increase in research and development expenditures was also the result of a $1.5 million increase in facilities and infrastructure costs.

The fiscal 2005 over 2004 increase of $10.2 million in research and development expenditures was attributable primarily to an increase in personnel and related costs of $8.4 million, primarily as a result of our acquisition of London Bridge.

In fiscal 2007, we expect that research and development expenditures as a percentage of revenues will be consistent with those incurred during fiscal 2006.

Selling, General and Administrative

Selling, general and administrative expenses consist principally of employee salaries and benefits, travel, overhead, advertising and other promotional expenses, corporate facilities expenses, legal expenses, business development expenses, and the cost of operating computer systems.

The fiscal 2006 over 2005 increase of $37.4 million in selling, general and administrative expenses was attributable to a $32.1 million increase in personnel and other labor-related costs and a $5.9 million increase in facilities and infrastructure costs, slightly offset by a $0.6 million net decrease in other expenses. The increase in personnel and labor-related costs resulted from a $22.6 million increase in share-based compensation expense due to the adoption of SFAS No. 123(R) and the remaining $9.5 million increase was primarily due to higher salary and commission costs. The increase in facilities and infrastructure was due to higher information systems costs.

The fiscal 2005 over 2004 increase of $41.0 million in selling, general and administrative expenses was attributable to a $35.0 million increase in personnel and other labor-related costs, a $2.6 million increase in travel costs, a $2.3 million increase in our provision for doubtful accounts, a $0.6 million increase in legal and accounting fees and a $0.5 million net increase in other expenses. The increase in personnel and labor-related costs and travel costs resulted primarily from our London Bridge and Braun acquisitions. Legal and accounting fees were impacted by higher professional fees that resulted from our assessment of internal controls over financial reporting as

38

required by the Sarbanes-Oxley Act and tax planning projects, partially offset by the impact of a $3.0 million charge recorded in fiscal 2004 in connection with a legal settlement.

In fiscal 2007, we expect that selling, general and administrative expenses as a percentage of revenues will be consistent with, or slightly lower than, those incurred during fiscal 2006.

Amortization of Intangible Assets

Amortization of intangible assets consists of amortization expense related to intangible assets recorded in connection with acquisitions accounted for by the purchase method of accounting. Our definite-lived intangible assets, consisting primarily of completed technology and customer contracts and relationships, are being amortized using the straight-line method or based on forecasted cash flows associated with the assets over periods ranging from two to fifteen years.

The fiscal 2006 over 2005 decline of $0.7 million in amortization expense was attributable to certain intangible assets becoming fully amortized.

The fiscal 2005 over 2004 increase in amortization expense was attributable to incremental amortization associated with our acquisitions of London Bridge and Braun in May 2004 and November 2004, respectively.

In fiscal 2007, we expect amortization expenses as a percentage of revenues will be slightly lower than the amortization expense incurred in 2006.

Restructuring and Acquisition-Related Expenses

The following table sets forth certain summary information on restructuring and acquisition-related expenses.

	Fiscal Year
	2006			2005		2004
				(In thousands)
Restructuring initiative, principally severance costs	$	5,198		$	—	$	—
Vacating excess lease space		12,954			—		460
Abandoned acquisition		2,184			—		767
Restructuring plan adjustment-leased space		(674	)		—		—
Total restructuring and acquisition related expense	$	19,662		$	—	$	1,227

In connection with a restructuring initiative in fiscal 2006, we incurred charges of $5.1 million for severance costs associated with a reduction of 190 employees primarily in product management, delivery and development functions. Cash payments for the majority of these severance costs were paid in fiscal 2006. As part of this restructuring initiative, we also recognized a $0.1 million charge associated with the abandonment of leased office space representing future cash obligations under the lease. These actions are forecasted to result in annualized savings of approximately $22 million, which represents compensation costs for terminated employees. However, as part of the restructuring initiative, we expect that the cost savings will be partially offset by additional staff required to support our new customer-centric approach to marketing our products.

As a result of vacating excess leased space located in California in fiscal 2006, we incurred a charge of $13.0 million, representing future cash lease obligations, net of estimated sublease income. We expect that the future lease obligations will be paid out over the next five years, which represents the remaining term of the lease. We expect this action to result in an annualized reduction of rent expense of approximately $3.6 million to $4.3 million through the remaining lease period.

In fiscal 2006, we recorded costs of $2.2 million in connection with an abandoned acquisition, consisting of third-party legal, accounting and other professional fees.

We recorded a $0.7 million gain in fiscal 2006 due to the sublease of office space that we had exited in fiscal 2002. The gain resulted from an adjustment to the liability established for the exit of the lease space and a refund received for past rent paid to the landlord.

During fiscal 2004, we wrote off deferred acquisition costs totaling $0.8 million in connection with an abandoned acquisition, consisting principally of third-party legal, accounting and other professional fees. In addition, we recorded a $0.5 million charge in fiscal 2004 related to the closure of a Fair Isaac office facility upon relocating its operations into an acquired London Bridge office facility.

Interest Income

Interest income is derived primarily from the investment of funds in excess of our immediate operating requirements.

The fiscal 2006 over 2005 increase of $6.8 million in interest income was attributable to higher interest and investment income yields due to market conditions and to a lesser extent higher average cash and investment balances. The increase in cash and investment balances resulted principally from cash provided by operating activities and proceeds received from the exercise of employee stock options.

The fiscal 2005 over 2004 decrease of $1.6 million in interest income was attributable to lower average cash and investment balances, partially offset by higher interest and investment income yields due to market conditions. The decrease in cash and investment balances resulted principally from cash used in investing and financing activities, including cash used for the redemption of our 5.25% Convertible Subordinated Notes (“Subordinated Notes”) in the fourth quarter of fiscal 2004, repurchases of common stock and acquisitions, partially offset by increases in net cash provided by operating activities.

Interest Expense

Interest expense recorded in fiscal 2006 relates to our $400.0 million of 1.5% Senior Convertible Notes (“Senior Notes”), including the amortization of debt issuance costs, and was consistent with the interest expense related to the Senior Notes recorded by us during fiscal 2005.

The fiscal 2005 over 2004 decrease of $8.6 million in interest expense was attributable to the redemption of our $150.0 million of Subordinated Notes in September 2004. Interest expense recorded during fiscal 2005 relates to our $400.0 million of Senior Notes, including the amortization of debt issuance costs, and is consistent with the interest expense related to the Senior Notes recorded by us in fiscal 2004.

Loss on Redemption of Convertible Subordinated Notes

In July 2004, our Board of Directors approved the cash redemption of all of the outstanding Subordinated Notes at a redemption price equal to 102.625% of the $150.0 million principal amount of the Subordinated Notes, pursuant to the redemption criteria in the indenture. In September 2004, we redeemed all of the outstanding Subordinated Notes with a cash outlay of $153.9 million, which resulted in the recognition of a loss on redemption of $11.1 million, representing the excess of the redemption cost over the carrying amount of the notes upon redemption.

Other Income (Expense), Net

Other income (expense), net consists primarily of realized investment gains/losses, exchange rate gains/losses resulting from re-measurement of foreign-denominated receivable and cash balances held by our U.S. reporting entities into the U.S. dollar functional currency at period-end market rates, net of the impact of offsetting forward exchange contracts, and other non-operating items.

Other expense, net was $0.2 million in fiscal 2006, compared with other income, net of $1.0 million in fiscal 2005. The change in other income (expense), net was primarily due to net foreign exchange losses of $0.9 million recognized in fiscal 2006, compared with a net foreign currency gain of $0.4 million recognized in fiscal 2005. The foreign exchange losses in fiscal 2006 were the result of unfavorable currency positions.

The fiscal 2005 over 2004 decrease of $6.0 million in other income was due to a decline in realized gains on sales of our marketable securities of $7.6 million, including a $6.6 million gain recognized in fiscal 2004 on the sale of our investment in Open Solutions, Inc. (“OSI”). The decline in other income was partially offset by foreign

40

exchange gains of $0.4 million recognized in fiscal 2005, compared with a net foreign currency loss of $0.9 million recorded in fiscal 2004. The foreign exchange loss in fiscal 2004 resulted from a $1.3 million net foreign exchange loss recorded in connection with our London Bridge acquisition. This net foreign exchange loss represented the excess of a loss recorded on a forward foreign exchange contract entered into in connection with this transaction over exchange rate gains resulting from the re-measurement of British pound-sterling cash balances held by one of our U.S. dollar functional currency entities for the purpose of funding the acquisition.

Provision for Income Taxes

Our effective tax rates were 35.0%, 30.7% and 39.1% in fiscal 2006, 2005 and 2004, respectively.

The increase in our effective tax rate in fiscal 2006 compared with fiscal 2005 was due to the recognition in fiscal 2005 of $10.6 million of tax benefits. These benefits were determined in conjunction with tax studies we performed with outside advisors that identified additional U.S. federal and state tax credits and other deductions related to prior years’ tax returns. The tax benefits recognized reflect our estimate of the effect of amended tax returns filed for fiscal 1998 through 2004. These tax benefits reduced our effective tax rate in fiscal 2005 by 5.5%. Excluding these tax benefits, the effective tax rate for fiscal 2005 would have been 36.2%.

Our effective tax rate in fiscal 2004 was adversely impacted by the inability to recognize research and development credits in the fourth quarter of fiscal 2004 due to the temporary expiration of this credit and from the inability to recognize a tax benefit on certain foreign losses.

Operating Income

Operating income	$	152,723		$	193,011		$	179,866			(40,288	)		13,145			(21	)%		7	%

The fiscal 2006 over fiscal 2005 decrease of $40.3 million in operating income was attributable primarily to an increase in share-based compensation expense due to the adoption of SFAS No. 123(R) and restructuring and acquisition-related charges. The decrease in operating income was partially offset by an increase in segment revenues. At the segment level, the increase in segment operating income was driven by increases of $22.1 million and $11.9 million in segment operating income within our Strategy Machine Solutions and Scoring Solutions segments, respectively, partially offset by a $10.4 million and $5.1 million decrease in segment operating income within our Analytic Software Tools and Professional Services segments. The increase in Strategy Machine Solutions segment operating income was attributable to increases in sales of higher margin product offerings and a decline in operating expenses, partially offset by the impact of revenue declines we experienced in marketing solutions and insurance and healthcare solutions. The increase in Scoring Solutions segment operating income was attributable primarily to an increase in revenues derived from risk scoring services at the credit reporting agencies and an increase in revenues derived from our own prescreening services. In our Analytic Software Tools segment,

41

the decline in segment operating income was due to a decrease in sales of perpetual licenses as well as increased product development and sales costs. The decrease in Professional Services segment operating income was the result of higher personnel and outside consultant costs.

The fiscal 2005 over fiscal 2004 increase in operating income was attributable primarily to an increase in segment revenues, which included a $67.4 million increase in revenues that resulted from our acquisitions in fiscal 2005 and 2004. The increase was partially offset by an increase of $6.8 million in the amortization of intangible assets that resulted from our acquisitions in fiscal 2004 and 2005. At the segment level, the increase in segment operating income was driven by increases of $23.7 million, $9.3 million and $2.9 million in segment operating income within our Scoring Solutions, Professional Services and Analytic Software Tools segments, respectively, partially offset by a $22.7 million decrease in segment operating income within our Strategy Machine Solutions segment. The increase in Scoring Solutions segment operating income was attributable primarily to an increase in revenues derived from risk scoring services at the credit reporting agencies, resulting from increased sales of scores for prescreening activities, and an increase in revenues derived from our own prescreening services. The increase in Professional Services segment operating income was the result of an increase in Precision Marketing service revenues and implementations of EDM products. In our Analytic Software Tools segment, higher segment operating income was due to an increase in sales of perpetual licenses for our EDM products. The decrease in Strategy Machine Solutions segment operating income was attributable to revenue declines we experienced in insurance and healthcare solutions and marketing solutions, the impact of negative operating margins associated with London Bridge product offerings, partially offset by increases in sales of higher margin product offerings.

Capital Resources and Liquidity

Cash Flows from Operating Activities

Our primary method for funding operations and growth has been through cash flows generated from operating activities. Net cash provided by operating activities decreased from $214.1 million in fiscal 2005 to $199.0 million in fiscal 2006. The comparison of fiscal 2006 to fiscal 2005 operating cash flows was impacted by a $20.8 million prepayment received in fiscal 2005 from a single customer for future services. Operating cash flows in fiscal 2006 were also negatively affected by payments of $11.3 million for restructuring and acquisition-related activities and the increase of $9.7 million in receivables, which reflects the increase in revenues and longer payment terms in certain customer contracts. In addition, prior to the adoption of SFAS No. 123(R), we presented all tax benefits for deductions resulting from the exercise of stock options as operating cash flows within our consolidated statements of cash flows. SFAS No. 123(R) requires the cash flows resulting from the tax benefits for tax deductions in excess of the compensation expense recorded for those options (excess tax benefits) to be classified as financing cash flows. Accordingly, the $7.1 million excess tax benefit that is classified as a financing cash inflow on the accompanying consolidated statements of cash flows in fiscal 2006 was classified as an operating cash inflow prior to the adoption of SFAS No. 123(R).

Net cash provided by operating activities increased from $199.1 million in fiscal 2004 to $214.1 million in fiscal 2005. The increase in fiscal 2005 operating cash flows was driven by the $31.8 million increase in net income and a $20.8 million prepayment received from a single customer for future services. Operating cash flows were negatively impacted by an increase in trade receivables of $8.2 million, which was the result of higher sales volumes and slower collections. In addition, operating cash flows were negatively affected by payments of $8.3 million for acquisition-related restructuring activities.

Cash Flows from Investing Activities

Net cash used in investing activities totaled $17.0 million in fiscal 2006 compared to $2.9 million in fiscal 2005. The change in cash flows from investing activities was attributable to a $41.3 million decrease in cash paid for acquisitions, due to our acquisitions of Braun and RulesPower in fiscal 2005, $22.7 million decrease in cash proceeds from a business disposition due to the sale in fiscal 2005 of London Bridge Phoenix Software, and an $18.1 million decline in proceeds from sales and maturities of marketable securities, net of purchases. In addition, capital expenditures increased by $15.0 million in fiscal 2006, which included spending on a new information systems data center.

42

Net cash used in investing activities totaled $2.9 million in fiscal 2005, compared to net cash provided by investing activities of $7.4 million in fiscal 2004. The change in cash flows from investing activities was attributable to a $281.1 million decline in proceeds from sales and maturities of marketable securities, net of purchases, a $243.4 million decrease in cash paid for acquisitions, due to our acquisition of London Bridge in fiscal 2004, and $22.7 million in cash proceeds related to our disposition of London Bridge Phoenix Software in fiscal 2005.

Cash Flows from Financing Activities

Net cash used in financing activities totaled $190.3 million in fiscal 2006, compared to $262.0 million in fiscal 2005. The decrease in cash used for financing activities was due to a $72.1 million decline in common stock repurchased. In addition, prior to the adoption of SFAS No. 123(R), we presented all tax benefits for deductions resulting from the exercise of stock options as operating cash flows within our consolidated statements of cash flows. SFAS No. 123(R) requires the cash flows resulting from the tax benefits for tax deductions in excess of the compensation expense recorded for those options (excess tax benefits) to be classified as financing cash flows. Accordingly, the $7.1 million excess tax benefit that is classified as a financing cash inflow on the accompanying consolidated statements of cash flows in fiscal 2006 was classified as an operating cash inflow prior to the adoption of SFAS No. 123(R). The decrease in cash used in financing activities was partially offset by a $7.7 million decline in proceeds from issuances of common stock under employee stock option and purchase plans.

Net cash used in financing activities totaled $262.0 million in fiscal 2005, compared to net cash used in financing activities of $206.4 million in fiscal 2004. The increase in cash used for financing activities was due to a $227.4 million increase in common stock repurchased. The increase was partially offset by $153.9 million of cash used in fiscal 2004 in connection with the September 2004 redemption of our Subordinated Notes and an $18.3 million increase in cash proceeds from common stock issued under employee stock option and purchase plans.

Repurchases of Common Stock

From time to time, we repurchase our common stock in the open market pursuant to programs approved by our Board of Directors. During fiscal 2006, 2005 and 2004, we expended $256.5 million, $328.5 million and $101.1 million, respectively, in connection with our repurchase of common stock under such programs. In November 2006, our Board of Directors approved a new common stock repurchase program that replaces our previous program and allows us to purchase shares of our common stock up to an aggregate cost of $500.0 million. During the period October 1, 2006, through December 1, 2006, we repurchased 3,342,500 shares of our common stock for an aggregate cost of $138.5 million.

Dividends

We paid quarterly dividends of two cents per share, or eight cents per year, during each of fiscal 2006, 2005 and 2004. Our dividend rate is set by the Board of Directors on a quarterly basis taking into account a variety of factors, including among others, our operating results and cash flows, general economic and industry conditions, our obligations, changes in applicable tax laws and other factors deemed relevant by the Board. Although we expect to continue to pay dividends at the current rate, our dividend rate is subject to change from time to time based on the Board’s business judgment with respect to these and other relevant factors.

1.5% Senior Convertible Notes

In August 2003, we issued $400.0 million of Senior Notes that mature on August 15, 2023. The Senior Notes become convertible into shares of Fair Isaac common stock, subject to the conditions described below, at an initial conversion price of $43.9525 per share, subject to adjustments for certain events. The initial conversion price is equivalent to a conversion rate of approximately 22.7518 shares of Fair Isaac common stock per $1,000 principal amount of the Senior Notes. Holders may surrender their Senior Notes for conversion, if any of the following conditions is satisfied: (i) prior to August 15, 2021, during any fiscal quarter, if the closing price of our common stock for at least 20 trading days in the 30 consecutive trading day period ending on the last day of the immediately preceding fiscal quarter is more than 120% of the conversion price per share of our common stock on the

43

corresponding trading day; (ii) at any time after the closing sale price of our common stock on any date after August 15, 2021 is more than 120% of the then current conversion price; (iii) during the five consecutive business day period following any 10 consecutive trading day period in which the average trading price of a Senior Note was less than 98% of the average sale price of our common stock during such 10 trading day period multiplied by the applicable conversion rate; provided, however, if, on the day before the conversion date, the closing price of our common stock is greater than 100% of the conversion price but less than or equal to 120% of the conversion price, then holders converting their notes may receive, in lieu of our common stock based on the applicable conversion rate, at our option, cash or common stock with a value equal to 100% of the principal amount of the notes on the conversion date; (iv) if we have called the Senior Notes for redemption; or (v) if we make certain distributions to holders of our common stock or we enter into specified corporate transactions. The conversion price of the Senior Notes will be adjusted upon the occurrence of certain dilutive events as described in the indenture, which include but are not limited to: (i) dividends, distributions, subdivisions, or combinations of our common stock; (ii) issuance of rights or warrants for the purchase of our common stock under certain circumstances; (iii) the distribution to all or substantially all holders of our common stock of shares of our capital stock, evidences of indebtedness, or other non-cash assets, or rights or warrants; (iv) the cash dividend or distribution to all or substantially all holders of our common stock in excess of certain levels; and (v) certain tender offer activities by us or any of our subsidiaries.

The Senior Notes are senior unsecured obligations of Fair Isaac and rank equal in right of payment with all of our unsecured and unsubordinated indebtedness. The Senior Notes are effectively subordinated to all of our existing and future secured indebtedness and existing and future indebtedness and other liabilities of our subsidiaries. The Senior Notes bear regular interest at an annual rate of 1.5%, payable on August 15 and February 15 of each year until August 15, 2008. Beginning August 15, 2008, regular interest will accrue at the rate of 1.5%, and be due and payable upon the earlier to occur of redemption, repurchase, or final maturity. In addition, the Senior Notes bear contingent interest during any six-month period from August 15 to February 14 and from February 15 to August 14, commencing with the six-month period beginning August 15, 2008, if the average trading price of the Senior Notes for the five trading day period immediately preceding the first day of the applicable six-month period equals 120% or more of the sum of the principal amount of, plus accrued and unpaid regular interest on, the Senior Notes. The amount of contingent interest payable on the Senior Notes in respect to any six-month period will equal 0.25% per annum of the average trading price of the Senior Notes for the five trading day period immediately preceding such six-month period.

We may redeem for cash all or part of the Senior Notes on and after August 15, 2008, at a price equal to 100% of the principal amount of the Senior Notes, plus accrued and unpaid interest. Holders may require us to repurchase for cash all or part of the $400 million of Senior Notes on August 15, 2007, August 15, 2008, August 15, 2013 and August 15, 2018, or upon a change in control, at a price equal to 100% of the principal amount of the Senior Notes being repurchased, plus accrued and unpaid interest.

On March 31, 2005, we completed an exchange offer for the Senior Notes, whereby holders of approximately 99.9% of the total principal amount of our Senior Notes exchanged their existing securities for new 1.5% Senior Convertible Notes, Series B (“New Notes”). The terms of the New Notes are similar to the terms of the Senior Notes described above, except that: (i) upon conversion, we will pay holders cash in an amount equal to the lesser of the principal amount of such notes and the conversion value of such notes, and to the extent such conversion value exceeds the principal amount of the notes, the remainder of the conversion obligation in cash or common shares or combination thereof; (ii) in the event of a change of control, we may be required in certain circumstances to pay a make-whole premium on the New Notes converted in connection with the change of control and (iii) if the conversion condition in the first clause (iii) in the third paragraph preceding this paragraph is triggered and the closing price of our common stock is greater than 100% of the conversion price but less than or equal to 120% of the conversion price, the holders converting New Notes shall receive cash with a value equal to 100% of the principal amount of New Notes on the conversion date.

Credit Agreement

In October 2006, we entered into a five-year $300 million unsecured revolving credit facility with a syndicate of banks. The credit facility may be increased to $500 million subject to certain terms and conditions. Proceeds from the credit facility can be used for capital requirements and general business purposes and may be used for the

44

refinancing of existing debt, acquisitions and repurchases 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 and (b) the Federal Funds rate plus 0.50% or (ii) LIBOR plus an applicable margin. The margin on LIBOR borrowings ranges from 0.30% to 0.55% and is determined based on our consolidated leverage ratio. In addition, we must pay utilization fees if borrowings and commitments under the credit facility exceed 50% of the total credit facility commitment, as well as facility fees. The credit facility contains certain restrictive covenants, including maintenance of consolidated leverage and fixed charge coverage ratios. The credit facility also contains covenants typical of unsecured facilities.

Capital Resources and Liquidity Outlook

As of September 30, 2006, we had $265.6 million in cash, cash equivalents and marketable security investments. We believe that these balances, as well as borrowings from our $300 million revolving credit facility and anticipated cash flows from operating activities, will be sufficient to fund our working and other capital requirements and any repayment of existing debt over the course of the next twelve months and for the foreseeable future. In the normal course of business, we evaluate the merits of acquiring technology or businesses, or establishing strategic relationships with or investing in these businesses. We may elect to use available cash and cash equivalents and marketable security investments to fund such activities in the future. In the event additional needs for cash arise, we may raise additional funds from a combination of sources, including the potential issuance of debt or equity securities. Additional financing might not be available on terms favorable to us, or at all. If adequate funds were not available or were not available on acceptable terms, our ability to take advantage of unanticipated opportunities or respond to competitive pressures could be limited.

Contractual Obligations

The following is a summary of our contractual obligations at September 30, 2006:

	Fiscal Year
	2007		2008		2009		2010		2011		Thereafter		Total
							(In thousands)
Senior Notes (1)	$	400,000	$	—	$	—	$	—	$	—	$	—	$	400,000
Operating lease obligations		25,088		24,295		21,529		19,141		13,748		24,467		128,268
Total commitments	$	425,088	$	24,295	$	21,529	$	19,141	$	13,748	$	24,467	$	528,268

(1) $400.0 million represents the aggregate principal amount of the Senior Notes. Our Senior Notes are classified in short-term debt in our consolidated balance sheet at September 30, 2006 because holders may require us to purchase the Senior Notes upon delivery of a written purchase notice on specific dates, the earliest of which is August 2007. Refer to Note 9 to our accompanying consolidated financial statements for more detailed information regarding the Senior Notes.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future material effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures, or capital resources.

Critical Accounting Policies and Estimates

We prepare our consolidated financial statements in conformity with U.S. generally accepted accounting principles. These accounting principles require management to make certain judgments and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. We periodically evaluate our estimates including those relating to revenue recognition, the allowance for doubtful accounts, goodwill and other intangible assets resulting from business acquisitions, internal-use software, income taxes and contingencies and litigation. We base our estimates on historical experience and various other

45

assumptions that we believe to be reasonable based on the specific circumstances, the results of which form the basis for making judgments about the carrying value of certain assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

We believe the following critical accounting policies involve the most significant judgments and estimates used in the preparation of our consolidated financial statements:

Revenue Recognition

Software license fee revenue is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred at our customer’s location, the fee is fixed or determinable and collection is probable. We use the residual method to recognize revenue when an arrangement includes one or more elements to be delivered at a future date and vendor-specific objective evidence (“VSOE”) of the fair value of all undelivered elements exists. VSOE of fair value is based on the normal pricing practices for those products and services when sold separately by us and customer renewal rates for post-contract customer support services. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is recognized as revenue. If evidence of the fair value of one or more undelivered elements does not exist, the revenue is deferred and recognized when delivery of those elements occurs or when fair value can be established. The determination of whether fees are fixed or determinable and collection is probable involves the use of assumptions. We evaluate contract terms and customer information to ensure that these criteria are met prior to our recognition of license fee revenue. Changes to the elements in a software arrangement, the ability to identify VSOE for those elements, the fair value of the respective elements, and change to a product’s estimated life cycle could materially impact the amount of earned and unearned revenue.

When software licenses are sold together with implementation or consulting services, license fees are recognized upon delivery provided that the above criteria are met, payment of the license fees is not dependent upon the performance of the services, and the services do not provide significant customization or modification of the software products and are not essential to the functionality of the software that was delivered. For arrangements with services that are essential to the functionality of the software, the license and related service revenues are recognized using contract accounting as described below.

If at the outset of an arrangement we determine that the arrangement fee is not fixed or determinable, revenue is deferred until the arrangement fee becomes due, assuming all other revenue recognition criteria have been met. If at the outset of an arrangement we determine that collectibility is not probable, revenue is deferred until the earlier of when collectibility becomes probable or the receipt of payment. If there is uncertainty as to the customer’s acceptance of our deliverables, revenue is not recognized until the earlier of receipt of customer acceptance, expiration of the acceptance period when we can demonstrate we meet the acceptance criteria.

Revenues from post-contract customer support services, such as software maintenance, are recognized on a straight-line basis over the term of the support period. The majority of our software maintenance agreements provide technical support as well as unspecified software product upgrades and releases when and if made available by us during the term of the support period.

Revenues recognized from our credit scoring, data processing, data management and internet delivery services are recognized as these services are performed, provided persuasive evidence of an arrangement exists, fees are fixed or determinable, and collection is reasonably assured. The determination of certain of our credit scoring and data processing revenues requires the use of estimates, principally related to transaction volumes in instances where these volumes are reported to us by our clients on a monthly or quarterly basis in arrears. In these instances, we estimate transaction volumes based on preliminary customer transaction information, if available, or based on average actual reported volumes for an immediate trailing period. Differences between our estimates and actual final volumes reported are recorded in the period in which actual volumes are reported. We have not experienced significant variances between our estimates and actual reported volumes in the past and anticipate that we will be able to continue to make reasonable estimates in the future. If for some reason we were unable to reasonably estimate transaction volumes in the future, revenue may be deferred until actual customer data was received, and this could have a material impact on our results of operations during the period of time that we changed accounting methods.

46

Transactional or unit-based license fees under software license arrangements, network service and internally-hosted software agreements are recognized as revenue based on system usage or when fees based on system usage exceed monthly minimum license fees, provided persuasive evidence of an arrangement exists, fees are fixed or determinable and collection is probable. The determination of certain of our transactional or unit-based license fee revenues requires the use of estimates, principally related to transaction usage or active account volumes in instances where this information is reported to us by our clients on a monthly or quarterly basis in arrears. In these instances, we estimate transaction volumes based on preliminary customer transaction information, if available, or based on average actual reported volumes for an immediate trailing period. Differences between our estimates and actual final volumes reported are recorded in the period in which actual volumes are reported. We have not experienced significant variances between our estimates and actual reported volumes in the past and anticipate that we will be able to continue to make reasonable estimates in the future. If for some reason we were unable to reasonably estimate customer account or transaction volumes in the future, revenue would be deferred until actual customer data was received, and this could have a material impact on our consolidated results of operations.

We provide consulting, training, model development and software integration services under both hourly-based time and materials and fixed-priced contracts. Revenues from these services are generally recognized as the services are performed. For fixed-price service contracts, we apply the percentage-of-completion method of contract accounting to determine progress towards completion, which requires the use of estimates. In such instances, management is required to estimate the input measures, generally based on hours incurred to date compared to total estimated hours of the project, with consideration also given to output measures, such as contract milestones, when applicable. Adjustments to estimates are made in the period in which the facts requiring such revisions become known and, accordingly, recognized revenues and profits are subject to revisions as the contract progresses to completion. Estimated losses, if any, are recorded in the period in which current estimates of total contract revenue and contract costs indicate a loss. If substantive uncertainty related to customer acceptance of services exists, we apply the completed contract method of accounting and defer the associated revenue until the contract is completed. If we are unable to accurately estimate the input measures used for percentage-of-completion accounting, revenue would be deferred until the contract is complete, and this could have a material impact on our consolidated results of operations.

Revenue recognized under the percentage-of-completion method in excess of contract billings is recorded as an unbilled receivable. Such amounts are generally billable upon reaching certain performance milestones as defined by individual contracts. Billings collected in advance of performance and recognition of revenue under contracts are recorded as deferred revenue.

In certain of our non-software arrangements, we enter into contracts that include the delivery of a combination of two or more of our service offerings. Typically, such multiple element arrangements incorporate the design and development of data management tools or systems and an ongoing obligation to manage, host or otherwise run solutions for our customer. Such arrangements are divided into separate units of accounting provided that the delivered item has stand-alone value and there is objective and reliable evidence of the fair value of the undelivered items. The total arrangement fee is allocated to the undelivered elements based on their fair values and to the initial delivered elements using the residual method. Revenue is recognized separately, and in accordance with our revenue recognition policy, for each element.

As described above, sometimes our customer arrangements have multiple deliverables, including service elements. Generally, our multiple element arrangements fall within the scope of specific accounting standards that provide guidance regarding the separation of elements in multiple-deliverable arrangements and the allocation of consideration among those elements (e.g., American Institute of Certified Public Accountants Statement of Position (“SOP”) No. 97-2, Software Revenue Recognition, as amended). If not, we apply the separation provisions of Emerging Issues Task Force (“EITF”) Issue No. 00-21, Revenue Arrangements with Multiple Deliverables. The provisions of EITF Issue No. 00-21 require us to unbundle multiple element arrangements into separate units of accounting when the delivered element(s) has stand-alone value and fair value of the undelivered element(s) exists. When we are able to unbundle the arrangement into separate units of accounting, we apply one of the accounting policies described above to each unit. If we are unable to unbundle the arrangement into separate units of accounting, we apply one of the accounting policies described above to the entire arrangement. Sometimes this results in recognizing the entire arrangement fee when delivery of the last element in a multiple element

47

arrangement occurs. For example, if the last undelivered element is a service, we recognize revenue for the entire arrangement fee as the service is performed, or if no pattern of performance is discernable, we recognize revenue on a straight-line basis over the term of the arrangement.

We record revenue on a net basis for those sales in which we have in substance acted as an agent or broker in the transaction.

Allowance for Doubtful Accounts

We make estimates regarding the collectibility of our accounts receivable. When we evaluate the adequacy of our allowance for doubtful accounts, we analyze specific accounts receivable balances, historical bad debts, customer creditworthiness, current economic trends and changes in our customer payment cycles. Material differences may result in the amount and timing of expense for any period if we were to make different judgments or utilize different estimates. If the financial condition of our customers deteriorates resulting in an impairment of their ability to make payments, additional allowances might be required. We have not experienced significant variances in the past between our estimated and actual doubtful accounts and anticipate that we will be able to continue to make reasonable estimates in the future. If for some reason we did not reasonably estimate the amount of our doubtful accounts in the future, it could have a material impact on our consolidated results of operations.

Business Acquisitions; Valuation of Goodwill and Other Intangible Assets

Our business acquisitions typically result in the recognition of goodwill and other intangible assets, and in certain cases non-recurring charges associated with the write-off of in-process research and development (“IPR&D”), which affect the amount of current and future period charges and amortization expense. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including identified intangible assets, in connection with our business combinations accounted for by the purchase method of accounting. We amortize our definite-lived intangible assets using the straight-line method or based on forecasted cash flows associated with the assets over the estimated useful lives, while IPR&D is recorded as a non-recurring charge on the acquisition date. Goodwill is not amortized, but rather is periodically assessed for impairment.

The determination of the value of these components of a business combination, as well as associated asset useful lives, requires management to make various estimates and assumptions. Critical estimates in valuing certain of the intangible assets include but are not limited to: future expected cash flows from product sales and services, maintenance agreements, consulting contracts, customer contracts, and acquired developed technologies and patents or trademarks; expected costs to develop the IPR&D into commercially viable products and estimating cash flows from the projects when completed; the acquired company’s brand awareness and market position, as well as assumptions about the period of time the acquired products and services will continue to be used in our product portfolio; and discount rates. Management’s estimates of fair value and useful lives are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable. Unanticipated events and circumstances may occur and assumptions may change. Estimates using different assumptions could also produce significantly different results.

We continually review the events and circumstances related to our financial performance and economic environment for factors that would provide evidence of the impairment of our intangible assets. When impairment indicators are identified with respect to our previously recorded intangible assets, then we test for impairment using undiscounted cash flows. If such tests indicate impairment, then we measure the impairment as the difference between the carrying value of the asset and the fair value of the asset, which is measured using discounted cash flows. Significant management judgment is required in forecasting of future operating results, which are used in the preparation of the projected discounted cash flows and should different conditions prevail, material write downs of net intangible assets and other long-lived assets could occur. We periodically review the estimated remaining useful lives of our acquired intangible assets. A reduction in our estimate of remaining useful lives, if any, could result in increased amortization expense in future periods.

We test goodwill for impairment at the reporting unit level at least annually during the fourth quarter of each fiscal year and more frequently if impairment indicators are identified. We have determined that our reporting units are the same as our reportable segments. The first step of the goodwill impairment test is a comparison of the fair

48

value of a reporting unit to its carrying value. We estimate the fair values of our reporting units using discounted cash flow valuation models and by comparing our reporting units to guideline publicly-traded companies. These methods require estimates of our future revenues, profits, capital expenditures, working capital, and other relevant factors, as well as selecting appropriate guideline publicly-traded companies for each reporting unit. We estimate these amounts by evaluating historical trends, current budgets, operating plans, industry data, and other relevant factors. The estimated fair value of each of our reporting units exceeded its respective carrying value in fiscal 2006, indicating the underlying goodwill of each reporting unit was not impaired as of our most recent testing date. Accordingly, we were not required to complete the second step of the goodwill impairment test. The timing and frequency of our goodwill impairment test is based on an ongoing assessment of events and circumstances that would more than likely reduce the fair value of a reporting unit below its carrying value. We will continue to monitor our goodwill balance and conduct formal tests on at least an annual basis or earlier when impairment indicators are present. There are various assumptions and estimates underlying the determination of an impairment loss, and estimates using different, but each reasonable, assumptions could produce significantly different results and materially affect the determination of fair value and/or goodwill impairment for each reporting unit. Therefore, the timing and recognition of impairment losses by us in the future, if any, may be highly dependent upon our estimates and assumptions. We believe that the assumptions and estimates utilized were appropriate based on the information available to management.

Share-Based Compensation

Prior to October 1, 2005, we accounted for our share-based employee compensation plans under the measurement and recognition provisions of Accounting Principles Board (“APB”) Opinion No. 25, Accounting for Stock Issued to Employees, and related Interpretations, as permitted by Financial Accounting Standards Board (“FASB”) SFAS No. 123, Accounting for Stock-Based Compensation. We generally recorded no employee compensation expense for options granted prior to October 1, 2005 as options granted generally had exercise prices equal to the fair market value of our common stock on the date of grant. We also recorded no compensation expense in connection with our 1999 Employee Stock Purchase Plan as the purchase price of the stock was not less than 85% of the lower of the fair market value of our common stock at the beginning of each offering period or at the end of each offering period. In accordance with SFAS No. 123, we disclosed our net income and earnings per share as if we had applied the fair value-based method in measuring compensation expense for our share-based incentive awards.

Effective October 1, 2005, we adopted the fair value recognition provisions of SFAS No. 123(R), Share-Based Payment, using the modified prospective transition method. Under that transition method, compensation expense that we recognize beginning on that date includes expense associated with the fair value of all awards granted on and after October 1, 2005, and expense for the unvested portion of previously granted awards outstanding on October 1, 2005. Results for prior periods have not been restated.

We estimate the fair value of options granted using the Black-Scholes option valuation model and the assumptions shown in Note 15 to the accompanying consolidated financial statements. We estimate the volatility of our common stock at the date of grant based on a combination of the implied volatility of publicly traded options on our common stock and our historical volatility rate, consistent with SFAS No. 123(R) and Securities and Exchange Commission Staff Accounting Bulletin No. 107 (“SAB 107”). Our decision to use implied volatility was based upon the availability of actively traded options on our common stock and our assessment that implied volatility is more representative of future stock price trends than historical volatility. We estimate expected term consistent with the simplified method identified in SAB 107 for share-based awards. We elected to use the simplified method as we changed the contractual life for share-based awards from ten to seven years starting in fiscal 2006. The simplified method calculates the expected term as the average of the vesting and contractual terms of the award. Previously, we estimated expected term based on historical exercise patterns. The dividend yield assumption is based on historical dividend payouts. The risk-free interest rate assumption is based on observed interest rates appropriate for the term of our employee options. We use historical data to estimate pre-vesting option forfeitures and record share-based compensation expense only for those awards that are expected to vest. For options granted, we amortize the fair value on a straight-line basis. All options are amortized over the requisite service periods of the awards, which are generally the vesting periods. If factors change we may decide to use different assumptions under the Black-Scholes

49

option valuation model in the future, which could materially affect our share-based compensation expense, net income and earnings per share.

Income Taxes

We use the asset and liability approach to account for income taxes. This methodology recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the carrying amounts and the tax base of assets and liabilities and operating loss and tax credit carryforwards. We then record a valuation allowance to reduce deferred tax assets to an amount that more likely than not will be realized. We consider future taxable income and ongoing prudent and feasible tax planning strategies in assessing the need for the valuation allowance, which requires the use of estimates. If we determine during any period that we could realize a larger net deferred tax asset than the recorded amount, we would adjust the deferred tax asset to increase income for the period or reduce goodwill if such deferred tax asset relates to an acquisition. Conversely, if we determine that we would be unable to realize a portion of our recorded deferred tax asset, we would adjust the deferred tax asset to record a charge to income for the period or increase goodwill if such deferred tax asset relates to an acquisition. Although we believe that our estimates are reasonable, there is no assurance that our the valuation allowance will not need to be increased to cover additional deferred tax assets that may not be realizable, and such an increase could have a material adverse impact on our income tax provision and results of operations in the period in which such determination is made. In addition, the calculation of tax liabilities also involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with management’s expectations could also have a material impact on our income tax provision and results of operations in the period in which such determination is made.

Contingencies and Litigation

We are subject to various proceedings, lawsuits and claims relating to products and services, technology, labor, shareholder and other matters. We are required to assess the likelihood of any adverse outcomes and the potential range of probable losses in these matters. If the potential loss is considered probable and the amount can be reasonably estimated, we accrue a liability for the estimated loss. If the potential loss is considered less than probable or the amount cannot be reasonably estimated, disclosure of the matter is considered. The amount of loss accrual or disclosure, if any, is determined after analysis of each matter, and is subject to adjustment if warranted by new developments or revised strategies. Due to uncertainties related to these matters, accruals or disclosures are based on the best information available at the time. Significant judgment is required in both the assessment of likelihood and in the determination of a range of potential losses. Revisions in the estimates of the potential liabilities could have a material impact on our consolidated financial position or consolidated results of operations.

New Accounting Pronouncements Not Yet Adopted

In July 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes, which prescribes a recognition threshold and measurement process for recording in the financial statements uncertain tax positions taken or expected to be taken in a tax return. Additionally, FIN 48 provides guidance on the derecognition, classification, accounting in interim periods and disclosure requirements for uncertain tax positions. The accounting provisions of FIN 48 will be effective for the Company beginning October 1, 2007. We are in the process of determining what effect, if any, the adoption of FIN 48 will have on our consolidated financial statements.

In September 2006, the Securities and Exchange Commission (“SEC”) released Staff Accounting Bulletin (“SAB”) No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, which provided the Staff’s view regarding the process of quantifying financial statement misstatements. SAB 108 requires an entity to quantify misstatements using both a balance sheet and income statement approach to determine if a misstatement is material. The evaluation requirements of SAB No. 108 are effective for years ending after November 15, 2006. We are in the process of determining what effect, if any, the adoption of SAB No. 108 will have on our consolidated financial statements.

50

In September 2006, the FASB issued SFAS No. 157, Fair Value Measures, which defines fair value, establishes a framework for measuring fair value and expands disclosures about assets and liabilities measured at fair value. The statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. We are in the process of determining what effect, if any, the adoption of SFAS No. 157 will have on our consolidated financial statements.

Item 7A.   Quantitative and Qualitative Disclosures About Market Risk

Market Risk Disclosures

We are exposed to market risk related to changes in interest rates, equity market prices, and foreign currency exchange rates. We do not use derivative financial instruments for speculative or trading purposes.

Interest Rate Risk

We maintain an investment portfolio consisting mainly of income securities with an average maturity of three years or less. These available-for-sale securities are subject to interest rate risk and will fall in value if market interest rates increase. We have the ability to hold our fixed income investments until maturity, and therefore we would not expect our operating results or cash flows to be affected to any significant degree by the effect of a sudden change in market interest rates on our securities portfolio. The following table presents the principal amounts and related weighted-average yields for our investments with interest rate risk at September 30, 2006 and 2005:

	September 30, 2006							September 30, 2005
	Cost		Carrying		Average			Cost		Carrying		Average
	Basis		Amount		Yield			Basis		Amount		Yield
					(In thousands)
Cash and cash equivalents	$	75,178	$	75,154		2.85	%	$	82,883	$	82,880		3.27	%
Short-term investments		152,446		152,141		4.79	%		146,543		146,088		3.26	%
Long-term investments		33,306		33,254		5.10	%		53,002		52,503		3.73	%
	$	260,930	$	260,549		4.27	%	$	282,428	$	281,471		3.36	%

We are the issuer of 1.5% Senior Convertible Notes (“Senior Notes”) that mature in August 2023. The fair value of our Senior Notes, including the New Notes issued in the exchange offer completed on March 31, 2005, as determined based on quoted market prices, may increase or decrease due to various factors, including fluctuations in the market price of our common stock, fluctuations in market interest rates and fluctuations in general economic conditions. See Management’s Discussion and Analysis of Financial Condition and Results of Operations — Capital Resources and Liquidity, above, for additional information on these notes. The following table presents the principal amounts, carrying amounts, and fair values for our Senior Notes at September 30, 2006 and 2005:

	September 30, 2006						September 30, 2005
			Carrying		Fair				Carrying		Fair
	Principal		Amount		Value		Principal		Amount		Value
					(In thousands)
Senior Notes	$	400,000	$	400,000	$	407,000	$	400,000	$	400,000	$	446,497

Forward Foreign Currency Contracts

We maintain a program to manage our foreign currency exchange rate risk on existing foreign currency receivable and bank balances by entering into forward contracts to sell or buy foreign currency. At period end, foreign-denominated receivables and cash balances held by our U.S. reporting entities are remeasured into the U.S. dollar functional currency at current market rates. The change in value from this remeasurement is then reported as a foreign exchange gain or loss for that period in our accompanying consolidated statements of income and the resulting gain or loss on the forward contract mitigates the exchange rate risk of the associated assets. All of our forward foreign currency contracts have maturity periods of less than three months. Such derivative financial instruments are subject to market risk.

51

The following table summarizes our outstanding forward foreign currency contracts, by currency at September 30, 2006:

	Contract Amount
	Foreign				Fair Value
	Currency		US$		US$
			(In thousands)
Sell foreign currency:
EURO (EUR)		EUR    6,650	$	8,468	$	—
Japanese Yen (YEN)		YEN 100,000		854		—
Buy foreign currency:
British Pound (GBP)		GBP    3,174	$	6,000	$	—

The forward foreign currency contracts were all entered into on September 30, 2006, therefore, the fair value was $0 on that date.

1.   Nature of Business and Summary of Significant Accounting Policies

  Fair Isaac Corporation

Incorporated under the laws of the State of Delaware, Fair Isaac Corporation is a provider of analytic, software and data management products and services that enable businesses to automate and improve decisions. Fair Isaac Corporation 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, healthcare organizations and government agencies.

In these consolidated financial statements, Fair Isaac Corporation is referred to as “we,” “us,” “our,” and “Fair Isaac.”

Principles of Consolidation and Basis of Presentation

The consolidated financial statements include the accounts of Fair Isaac and its subsidiaries. All intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. These estimates and assumptions include, but are not limited to, assessing the following: the recoverability of accounts receivable, goodwill and other intangible assets, software development costs and deferred tax assets; the ability to estimate hours in connection with fixed-fee service contracts, the ability to estimate transactional-based revenues for which actual transaction volumes have not yet been received, and the determination of whether fees are fixed or determinable and collection is probable or reasonably assured.

Adoption of Accounting Pronouncement

We adopted the Emerging Issues Task Force (“EITF”) consensus with respect to Issue No. 04-8, The Effect of Contingently Convertible Instruments on Diluted Earnings Per Share, during fiscal 2005. This consensus requires us to consider all instruments with contingent conversion features that are based on the market price of our own stock in our diluted earnings per share calculation, regardless of whether the market price conversion triggers are met. As required by the consensus, we have restated our diluted earnings per share calculations for fiscal 2004 to include the shares of our common stock issuable upon conversion of our Senior Convertible Notes (“Senior Notes”) using the “if converted” method.

Cash and Cash Equivalents

Cash and cash equivalents consist of cash in banks and investments with a maturity of 90 days or less at time of purchase.

Fair Value of Financial Instruments

The fair value of certain of our financial instruments, including cash and cash equivalents, receivables, and other current assets, accounts payable, accrued compensation and employee benefits, and other accrued liabilities, approximate their carrying amounts because of the short-term maturity of these instruments. The fair values of our cash and cash equivalents, marketable security investments are disclosed in Note 4. The fair value of our cost-method investment approximates its recorded value. The fair value of our senior convertible notes is disclosed in Note 9.

Investments

Management determines the appropriate classification of our investments in marketable debt and equity securities at the time of purchase, and re-evaluates this designation at each balance sheet date. While it is our intent to hold debt securities to maturity, our investments in U.S. government obligations and marketable equity and debt securities that have readily determinable fair values are classified as available-for-sale, as the sale of such securities may be required prior to maturity to implement management strategies. Therefore, such securities are carried at fair value with unrealized gains or losses related to these securities included in comprehensive income (loss). Realized gains and losses are included in other income (expense), net. The cost of investments sold is based on the specific identification method. Losses resulting from other than temporary declines in fair value are charged to operations. Investments with remaining maturities over one year are classified as long-term investments.

Our investments in equity securities of companies over which we do not have significant influence are accounted for under the cost method. Investments in which we own 20% to 50% and exercise significant influence over operating and financial policies are accounted for using the equity method. Under the equity method, the investment is originally recorded at cost and adjusted to recognize our share of net earnings or losses of the investee, limited to the extent of our investment in, advances to, and financial guarantees for the investee. Under the cost method, the investment is originally recorded at cost and adjusted for additional contributions or distributions. Management periodically reviews equity-method and cost-method investments for instances where fair value is less than the carrying amount and the decline in value is determined to be other than temporary. If the decline in value is judged to be other than temporary, the carrying amount of the security is written down to fair value and the resulting loss is charged to operations.

Concentration of Risk

Financial instruments that potentially expose us to concentrations of risk consist primarily of cash and cash equivalents, marketable securities and accounts receivable, which are generally not collateralized. Our policy is to place our cash, cash equivalents, and marketable securities with high credit quality financial institutions, commercial corporations and government agencies in order to limit the amount of credit exposure. We have established guidelines relative to diversification and maturities for maintaining safety and liquidity. We generally do not require collateral from our customers, but our credit extension and collection policies include analyzing the financial condition of potential customers, establishing credit limits, monitoring payments, and aggressively pursuing delinquent accounts. We maintain allowances for potential credit losses.

Property and Equipment

Property and equipment are recorded at cost less accumulated depreciation and amortization. Major renewals and improvements are capitalized, while repair and maintenance costs are expensed as incurred. Depreciation and amortization charges are calculated using the straight-line method over the following estimated useful lives:

	Estimated Useful Life
Data processing equipment and software	2 to 3 years
Office furniture, vehicles and equipment	3 to 7 years
Leasehold improvements	Shorter of estimated useful life or lease term

The cost and accumulated depreciation for property and equipment sold, retired or otherwise disposed of are removed from the accounts and resulting gains or losses are recorded in operations. Depreciation and amortization on property and equipment totaled $23.6 million, $24.3 million and $26.1 million during fiscal 2006, 2005 and 2004, respectively.

Internal-use Software

Costs incurred to develop internal-use software during the application development stage are capitalized and reported at cost, subject to an impairment test as described below. Application development stage costs generally include costs associated with internal-use software configuration, coding, installation and testing. Costs of significant upgrades and enhancements that result in additional functionality are also capitalized whereas costs incurred for maintenance and minor upgrades and enhancements are expensed as incurred. Capitalized costs are amortized using the straight-line method over two to three years.

We assess potential impairment of capitalized internal-use software whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows that are expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell. We capitalized $0.8 million, $1.1 million and $4.8 million in fiscal 2006, 2005 and 2004, respectively. Amortization expense related to internal-use software was $2.5 million, $3.0 million and $2.8 million in fiscal 2006, 2005 and 2004, respectively.

Capitalized Software Development Costs

All costs incurred prior to the resolution of unproven functionality and features, including new technologies, are expensed as research and development. After the uncertainties have been tested and the development issues have been resolved and technological feasibility is achieved, subsequent direct costs such as coding, debugging and testing are capitalized. Capitalized software development costs are amortized using the greater of the amount computed using (a) the ratio that current gross revenues for a product bear to the total of current and anticipated future gross revenues for that product or (b) the straight-line method over the remaining estimated economic life of the product. Capitalized software development costs were $0, net of accumulated amortization of $3.4 million as of September 30, 2006 and 2005, and are included in other long-term assets in the accompanying consolidated balance sheets. Amortization expense related to capitalized software development costs totaled $0, $1.3 million and $1.7 million during fiscal 2006, 2005 and 2004, respectively.

At each balance sheet date, we compare a product’s unamortized capitalized cost to the product’s estimated net realizable value. To the extent unamortized capitalized costs exceed net realizable value based on the product’s estimated future gross revenues, reduced by the estimated future costs of completing and disposing of the product, the excess is written off. This analysis requires us to estimate future gross revenues associated with certain products, and the future costs of completing and disposing of certain products. If these estimates change, reductions or write-offs of capitalized software development costs could result. No write-offs were recorded during fiscal 2006, 2005 or 2004.

Goodwill and Intangible Assets

Goodwill and intangible assets with indefinite lives are tested for impairment at least annually or more frequently if impairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of net assets acquired, including identified intangible assets, in connection with our business combinations accounted for by the purchase method of accounting (see Note 2).

61

FAIR ISAAC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Years Ended September 30, 2006, 2005 and 2004

We amortize our intangible assets, which result from our acquisitions accounted for under the purchase method of accounting, using the straight-line method or based on the forecasted cash flows associated with the assets over the following estimated useful lives:

	Estimated Useful Life
Completed technology		5 to 6 years
Customer contracts and relationships		2 to 15 years
Trade names		5 years
Other		3 years

Revenue Recognition

Software license fee revenue is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred at our customer’s location, the fee is fixed or determinable and collection is probable. We use the residual method to recognize revenue when an arrangement includes one or more elements to be delivered at a future date and vendor-specific objective evidence (“VSOE”) of the fair value of all undelivered elements exists. VSOE of fair value is based on the normal pricing practices for those products and services when sold separately by us and customer renewal rates for post-contract customer support services. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the arrangement fee is recognized as revenue. If evidence of the fair value of one or more undelivered elements does not exist, the revenue is deferred and recognized when delivery of those elements occurs or when fair value can be established. The determination of whether fees are fixed or determinable and collection is probable involves the use of assumptions. We evaluate contract terms and customer information to ensure that these criteria are met prior to our recognition of license fee revenue.

When software licenses are sold together with implementation or consulting services, license fees are recognized upon delivery provided that the above criteria are met, payment of the license fees is not dependent upon the performance of the services, and the services do not provide significant customization or modification of the software products and are not essential to the functionality of the software that was delivered. For arrangements with services that are essential to the functionality of the software, the license and related service revenues are recognized using contract accounting as described below.

If at the outset of an arrangement we determine that the arrangement fee is not fixed or determinable, revenue is deferred until the arrangement fee becomes due assuming all other revenue recognition criteria have been met. If at the outset of an arrangement we determine that collectibility is not probable, revenue is deferred until the earlier of when collectibility becomes probable or the receipt of payment. If there is uncertainty to the customer’s acceptance of our deliverables, revenue is not recognized until the earlier of receipt of customer acceptance, expiration of the acceptance period or where we can demonstrate we meet the acceptance criteria.

Revenues from post-contract customer support services, such as software maintenance, are recognized on a straight-line basis over the term of the support period. The majority of our software maintenance agreements provide technical support as well as unspecified software product upgrades and releases when and if made available by us during the term of the support period.

Revenues recognized from our credit scoring, data processing, data management and internet delivery services are recognized as these services are performed, provided persuasive evidence of an arrangement exists, fees are fixed or determinable, and collection is reasonably assured. The determination of certain of our credit scoring and data processing revenues requires the use of estimates, principally related to transaction volumes in instances where these volumes are reported to us by our clients on a monthly or quarterly basis in arrears. In these instances, we estimate transaction volumes based on preliminary customer transaction information, if available, or based on

62

FAIR ISAAC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Years Ended September 30, 2006, 2005 and 2004

average actual reported volumes for an immediate trailing period. Differences between our estimates and actual final volumes reported are recorded in the period in which actual volumes are reported.

Transactional or unit-based license fees under software license arrangements, network service and internally-hosted software agreements are recognized as revenue based on system usage or when fees based on system usage exceed monthly minimum license fees, provided persuasive evidence of an arrangement exists, fees are fixed or determinable and collection is probable. The determination of certain of our transactional or unit-based license fee revenues requires the use of estimates, principally related to transaction usage or active account volumes in instances where this information is reported to us by our clients on a monthly or quarterly basis in arrears. In these instances, we estimate transaction volumes based on preliminary customer transaction information, if available, or based on average actual reported volumes for an immediate trailing period. Differences between our estimates and actual final volumes reported are recorded in the period in which actual volumes are reported.

We provide consulting, training, model development and software integration services under both hourly-based time and materials and fixed-priced contracts. Revenues from these services are generally recognized as the services are performed. For fixed-price service contracts, we apply the percentage-of-completion method of contract accounting to determine progress towards completion, which requires the use of estimates. In such instances, management is required to estimate the input measures, generally based on hours incurred to date compared to total estimated hours of the project, with consideration also given to output measures, such as contract milestones, when applicable. Adjustments to estimates are made in the period in which the facts requiring such revisions become known and, accordingly, recognized revenues and profits are subject to revisions as the contract progresses to completion. Estimated losses, if any, are recorded in the period in which current estimates of total contract revenue and contract costs indicate a loss. If substantive uncertainty related to customer acceptance of services exists, we apply the completed contract method of accounting and defer the associated revenue until the contract is completed.

Revenue recognized under the percentage-of-completion method in excess of contract billings is recorded as an unbilled receivable. Such amounts are generally billable upon reaching certain performance milestones as defined by individual contracts. Billings collected in advance of performance and recognition of revenue under contracts are recorded as deferred revenue.

In certain of our non-software arrangements, we enter into contracts that include the delivery of a combination of two or more of our service offerings. Typically, such multiple element arrangements incorporate the design and development of data management tools or systems and an ongoing obligation to manage, host or otherwise run solutions for our customer. Such arrangements are divided into separate units of accounting provided that the delivered item has stand-alone value and there is objective and reliable evidence of the fair value of the undelivered items. The total arrangement fee is allocated to the undelivered elements based on their fair values and to the initial delivered elements using the residual method. Revenue is recognized separately, and in accordance with our revenue recognition policy, for each element.

As described above, sometimes our customer arrangements have multiple deliverables, including service elements. Generally, our multiple element arrangements fall within the scope of specific accounting standards that provide guidance regarding the separation of elements in multiple-deliverable arrangements and the allocation of consideration among those elements (e.g., American Institute of Certified Public Accountants Statement of Position (“SOP”) No. 97-2, Software Revenue Recognition, as amended). If not, we apply the separation provisions of Emerging Issues Task Force (“EITF”) Issue No. 00-21, Revenue Arrangements with Multiple Deliverables. The provisions of EITF Issue No. 00-21 require us to unbundle multiple element arrangements into separate units of accounting when the delivered element(s) has stand-alone value and fair value of the undelivered element(s) exists. When we are able to unbundle the arrangement into separate units of accounting, we apply one of the accounting policies described above to each unit. If we are unable to unbundle the arrangement into separate units of

63

FAIR ISAAC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Years Ended September 30, 2006, 2005 and 2004

accounting, we apply one of the accounting policies described above to the entire arrangement. Sometimes this results in recognizing the entire arrangement fee when delivery of the last element in a multiple element arrangement occurs. For example, if the last undelivered element is a service, we recognize revenue for the entire arrangement fee as the service is performed, or if no pattern of performance is discernable, we recognize revenue on a straight-line basis over the term of the arrangement.

We record revenue on a net basis for those sales in which we have in substance acted as an agent or broker in the transaction.

Allowance for Doubtful Accounts

We make estimates regarding the collectibility of our accounts receivable. When we evaluate the adequacy of our allowance for doubtful accounts, we analyze specific accounts receivable balances, historical bad debts, customer creditworthiness, current economic trends and changes in our customer payment cycles. Material differences may result in the amount and timing of expense for any period if we were to make different judgments or utilize different estimates. If the financial condition of our customers deteriorates resulting in an impairment of their ability to make payments, additional allowances might be required.

Income Taxes

Income taxes are recognized during the year in which transactions enter into the determination of financial statement income, with deferred taxes being provided for temporary differences between amounts of assets and liabilities for financial reporting purposes and such amounts as measured by tax laws. A deferred income tax asset or liability is computed for the expected future impact of differences between the financial reporting and tax bases of assets and liabilities as well as the expected future tax benefit to be derived from tax loss and tax credit carryforwards. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount “more likely than not” to be realized in future tax returns. Tax rate changes are reflected in income during the period the changes are enacted.

Earnings per Share

Diluted earnings per share are based on the weighted-average number of common shares outstanding and potential common shares. Potential common shares result from the assumed exercise of outstanding stock options or other potentially dilutive equity instruments, including our outstanding senior convertible notes, when they are dilutive under the treasury stock method or the if-converted method. Basic earnings per share are computed on the basis of the weighted-average number of common shares outstanding.

Comprehensive Income

Comprehensive income is the change in our equity (net assets) during each period from transactions and other events and circumstances from non-owner sources. It includes net income, foreign currency translation adjustments and unrealized gains and losses, net of tax, on our investments in marketable securities.

Foreign Currency

We have determined that the functional currency of each foreign operation is the local currency. Assets and liabilities denominated in their local foreign currencies are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenues and expenses are translated at average rates of exchange prevailing during the period. Translation adjustments are accumulated as a separate component of stockholders’ equity.

64

FAIR ISAAC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Years Ended September 30, 2006, 2005 and 2004

From time to time, we utilize forward contract instruments to manage market risks associated with fluctuations in certain foreign currency exchange rates as they relate to specific balances of accounts receivable and cash denominated in foreign currencies. It is our policy to use derivative financial instruments to protect against market risks arising in the normal course of business. Our policies prohibit the use of derivative instruments for the sole purpose of trading for profit on price fluctuations or to enter into contracts that intentionally increase our underlying exposure. All of our forward foreign currency contracts have maturity periods of less than three months.

At the end of the reporting period, foreign currency denominated receivable and cash balances are remeasured into the functional currency of the reporting entities at current market rates. The change in value from this remeasurement is reported as a foreign exchange gain or loss for that period in other income (expense) in the accompanying consolidated statements of income. The resulting gains or losses from the forward foreign currency contracts described above, which are also included in other income (expense), mitigate the exchange rate risk of the associated assets.

Share-Based Compensation

Prior to October 1, 2005, we accounted for our share-based employee compensation plans under the measurement and recognition provisions of Accounting Principles Board Opinion (“APB”) No. 25, Accounting for Stock Issued to Employees, and related Interpretations, as permitted by Financial Accounting Standards Board Statement of Financial Accounting Standards (“SFAS”) No. 123, Accounting for Stock-Based Compensation. We generally recorded no employee compensation expense for options granted prior to October 1, 2005 as options granted generally had exercise prices equal to the fair market value of our common stock on the date of grant. We also recorded no compensation expense in connection with our 1999 Employee Stock Purchase Plan (“Purchase Plan”) as the purchase price of the stock was not less than 85% of the lower of the fair market value of our common stock at the beginning of each offering period or at the end of each offering period. In accordance with SFAS No. 123, we disclosed our net income and earnings per share as if we had applied the fair value-based method in measuring compensation expense for our share-based incentive awards.

Effective October 1, 2005, we adopted the fair value recognition provisions of SFAS No. 123(R), Share-Based Payment, using the modified prospective transition method. Under that transition method, compensation expense that we recognize beginning on that date includes expense associated with the fair value of all awards granted on and after October 1, 2005, and expense for the unvested portion of previously granted awards outstanding on October 1, 2005. Results for prior periods have not been restated. See Note 15 for further discussion of the impact of the adoption of SFAS No. 123(R).

Impairment of Long-lived Assets

We assess potential impairment to long-lived assets and certain identifiable intangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to the future undiscounted net cash flows that are expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. We determined that our long-lived intangible assets were not impaired at September 30, 2006, 2005 or 2004. Assets to be disposed of are reported at the lower of the carrying amount or fair value less costs to sell.

Advertising and Promotion Costs

Advertising and promotion costs are expensed as incurred. Advertising and promotion costs totaled $4.3 million, $5.3 million and $6.5 million in fiscal 2006, 2005 and 2004, respectively, and are included in selling, general and administrative expenses in the accompanying consolidated statements of income.

New Accounting Pronouncements Not Yet Adopted

In July 2006, the FASB issued FASB Interpretation No. 48 (“FIN 48”), Accounting for Uncertainty in Income Taxes, which prescribes a recognition threshold and measurement process for recording in the financial statements uncertain tax positions taken or expected to be taken in a tax return. Additionally, FIN 48 provides guidance on the derecognition, classification, accounting in interim periods and disclosure requirements for uncertain tax positions. The accounting provisions of FIN 48 will be effective for the Company beginning October 1, 2007. We are in the process of determining what effect, if any, the adoption of FIN 48 will have on our consolidated financial statements.

In September 2006, the Securities and Exchange Commission (“SEC”) released Staff Accounting Bulletin (“SAB”) No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, which provided the Staff’s view regarding the process of quantifying financial statement misstatements. SAB 108 requires an entity to quantify misstatements using both a balance sheet and income statement approach to determine if a misstatement is material. The evaluation requirements of SAB No. 108 are effective for years ending after November 15, 2006. We are in the process of determining what effect, if any, the adoption of SAB No. 108 will have on our consolidated financial statements.

In September 2006, the FASB issued SFAS No. 157, Fair Value Measures, which defines fair value, establishes a framework for measuring fair value and expands disclosures about assets and liabilities measured at fair value. The statement is effective for financial statements issued for fiscal years beginning after November 15, 2007. We are in the process of determining what effect, if any, the adoption of SFAS No. 157 will have on our consolidated financial statements.

2.   Acquisitions

RulesPower, Inc.

On September 23, 2005, we acquired certain assets of RulesPower, Inc. (“RulesPower”), a leading provider of analytics and decision management technology, in exchange for cash consideration of $6.5 million. The purpose of this acquisition was to acquire RulesPower’s high-performance business rules management systems. These systems utilize proprietary execution engines that help users manage large amounts of data by executing rules faster and more efficiently. We intend to integrate this technology into Blaze Advisor system’s existing performance optimization capabilities, rules repository, developer tools, templates for business user rules management and other Fair Isaac products in which the Blaze Advisor system is embedded. We accounted for this transaction using the purchase method of accounting. Our allocation of the purchase price included $5.3 million for goodwill and $1.2 million for intangible assets, consisting of core technology. The acquired intangible assets have an estimated useful life of five years and are being amortized over this period using the straight-line method. The goodwill was allocated entirely to our Analytical Software Tools operating segment and will be deductible for tax purposes.

Braun Consulting, Inc.

On November 10, 2004, we acquired all of the issued and outstanding stock of Braun Consulting, Inc. (“Braun”), a marketing strategy and technology consulting firm, in exchange for cash consideration of $37.1 million and contingent cash consideration of $3.3 million payable to a former Braun shareholder if certain revenue parameters are achieved during either the fiscal year ended September 30, 2005, the two fiscal years ended September 30, 2006, or the three fiscal years ended September 30, 2007. These revenue parameters were not achieved during fiscal 2006 or 2005. The acquisition of Braun was consummated principally to complement our marketing solutions and services related to marketing strategy and customer management technologies, as well as to expand our capabilities in markets targeted for growth, including healthcare, retail and pharmaceuticals. Braun is

included in the Professional Services operating segment. The results of operations of Braun have been included in our results prospectively from November 10, 2004.

The total purchase price, excluding contingent consideration, is summarized as follows (in thousands):

Total cash consideration	$	37,093
Acquisition-related costs		615
Fair value of options to purchase Fair Isaac common stock, less $0.4 million representing the portion of the intrinsic value of unvested options allocated to unearned compensation		2,023
Total purchase price	$	39,731

In connection with the acquisition, we issued 182,000 options to purchase Fair Isaac common stock in exchange for outstanding Braun options. The table above reflects the total fair value of these options based on application of the Black-Scholes option pricing model, less the portion of the intrinsic value related to unvested options, which was allocated to unearned compensation.

Our allocation of the purchase price was as follows (in thousands):

Assets:
Cash, cash equivalents and marketable securities available for sale	$	9,643
Receivables, net		7,196
Prepaid expenses and other current assets		645

The acquired customer contracts and relationships, which include backlog, have a weighted average useful life of approximately 4.5 years and are being amortized over their estimated useful lives using the straight-line method. The goodwill was allocated to our Professional Services operating segment, and will not be deductible for tax purposes.

London Bridge Software Holdings plc

On April 26, 2004, our Board of Directors, together with the Board of Directors of London Bridge Software Holdings plc (“London Bridge”), a provider of intelligent business software, announced that they had reached

67

FAIR ISAAC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Years Ended September 30, 2006, 2005 and 2004

agreement on the terms of a recommended cash offer (the “Offer”) to be made by us and by Hawkpoint Partners Limited on our behalf outside of the United States for the entire issued and to be issued ordinary share capital of London Bridge. The Offer was made on April 30, 2004.

On May 28, 2004, we announced that valid acceptances of the Offer had been received in respect of a total of approximately 159.6 million London Bridge shares, representing approximately 93.4% of the issued share capital of London Bridge. Accordingly, all conditions related to the Offer were deemed to have been satisfied, and the Offer was declared unconditional by us in all respects. As of June 30, 2004, acceptances in respect of approximately 96% of the issued London Bridge share capital had been received, and during our fourth quarter ended September 30, 2004, we acquired all remaining outstanding London Bridge shares through compulsory acquisition procedures under U.K. law. Accordingly, as of September 30, 2004, we owned 100% of London Bridge’s issued share capital.

London Bridge delivers solutions for the management of retail debt and deposit origination, collection and recovery and the provision of core banking systems to its target markets. These markets include retail financial services and range from telecommunications, utilities and governmental agencies to other service providers and to the debt collection industry. Our acquisition of London Bridge was consummated principally to incorporate London Bridge’s software and systems for collections and recovery into our existing portfolio, and extend our ability to deliver analytics-driven strategies across the entire credit customer lifecycle. This acquisition was also made to enhance our presence and growth opportunities internationally.

We accounted for this transaction using the purchase method of accounting. The results of operations of London Bridge have been included in our results prospectively from May 28, 2004.

The total purchase price is summarized as follows (in thousands):

Total cash consideration for share capital	$	303,025
Acquisition-related costs		5,865
Fair value of options to purchase Fair Isaac common stock		1,320
Total purchase price of acquisition	$	310,210

In connection with the acquisition, we issued 99,096 options to purchase Fair Isaac common stock in exchange for certain London Bridge options. The table above reflects the total fair value of these options based on application of the Black-Scholes option pricing model. All of these exchanged options were issued out-of-the money (zero intrinsic value) commensurate with that of the London Bridge options that were replaced. Accordingly, no portion of the fair value was allocated to unearned future compensation.

The acquired intangible assets have a weighted average useful life of approximately 7.3 years and are being amortized using the straight-line method over their estimated useful lives as follows: completed technology, six years; and customer contracts and relationships, nine years. In addition, no value was recorded to in-process research and development. The goodwill was allocated to our Strategy Machine Solutions and Analytic Software Tools operating segments in the amounts of $181.5 million and $34.7 million, respectively. None of this goodwill is deductible for tax purposes.

During the quarter ended June 30, 2004, in connection with our acquisition of London Bridge, we entered into a forward foreign currency contract to sell £170.0 million for $300.1 million. This contract was entered into to offset exchange rate transaction gains or losses on British Pounds cash balances that were held by our wholly-owned acquiring subsidiary, whose functional currency is that of the U.S. Dollar, for the purpose of funding the London Bridge acquisition. We reduced the notional amount of the forward currency contract in connection with the payment of consideration to the selling shareholders, and settled the contract in the fourth quarter of fiscal 2004. During fiscal 2004, we recorded realized losses on this contract totaling $10.4 million, which is included in other income, net in the accompanying consolidated statements of income. These losses were principally offset by foreign currency transaction gains of $9.0 million, which are also included in other income, net.

Seurat Company

On October 1, 2003, we acquired substantially all of the assets of Seurat Company (“Seurat”) for cash consideration of $5.0 million. Seurat is a provider of solutions and services that help companies target, acquire and retain customers through creative marketing strategies. We accounted for this transaction using the purchase method of accounting. The results of operations of Seurat have been included in our results prospectively from October 1, 2003. Our allocation of the purchase price, including $0.1 million in acquisition costs, was as follows: (i) $3.6 million was allocated to net tangible assets, consisting principally of receivables and property and

equipment, (ii) $1.4 million was allocated to intangible assets, consisting of acquired customer contracts and relationships, and (iii) $0.1 million was allocated to goodwill. The acquired intangible assets have an estimated useful life of five years and are being amortized over this period using the straight-line method. The goodwill was allocated entirely to our Strategy Machine Solutions operating segment, all of which is deductible for tax purposes.

3.   Sales of Product Line Assets

In November 2004, we sold all of the issued and outstanding stock of London Bridge Phoenix Software, Inc. (“Phoenix”) to Harland Financial Solutions, Inc. (“Harland”). In connection with this disposition, we sold all of the Phoenix related assets, including all Phoenix bank processing solutions, the associated customer base, intellectual property rights and other related assets to Harland in exchange for cash consideration of $22.7 million and the assumption of substantially all Phoenix liabilities by Harland. Phoenix was an indirectly wholly-owned subsidiary that we acquired in connection with our acquisition of London Bridge in May 2004. As this disposition occurred shortly after the London Bridge acquisition and the fair value of Phoenix did not change significantly from the date of the London Bridge acquisition, no gain or loss was recorded in connection with this transaction. The excess of the consideration received over the book value of the net assets sold in this disposition, amounting to $15.1 million, was recorded as a decrease to goodwill in the Strategy Machines Solutions segment.

The long-term marketable equity securities represent securities held under a supplemental retirement and savings plan for certain officers and senior management employees, which are distributed upon termination or retirement of the employees.

The following table shows the gross unrealized losses and fair value of our investments with unrealized losses that are not deemed to be other-than-temporarily impaired, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at September 30, 2006 and 2005:

The unrealized losses from our fixed income securities at September 30, 2006 are primarily attributable to changes in interest rates. Because we have the ability and intent to hold these fixed income securities until a recovery of fair value, which may be maturity, we do not consider these securities to be other-than temporarily impaired at September 30, 2006.

Less allowance for doubtful accounts		(6,006	)		(7,222	)
Receivables, net	$	165,806		$	156,375

Unbilled receivables represent revenue recorded in excess of amounts billable pursuant to contract provisions and generally become billable at contractually specified dates or upon the attainment of milestones. Unbilled amounts are expected to be realized within one year. During fiscal 2006, 2005 and 2004, we increased our allowance for the provision for doubtful accounts by $2.2 million, $3.7 million and $1.4 million, respectively, recorded an allowance for doubtful accounts on acquired receivables of $0, $0.5 million and $8.9 million, respectively, and wrote off receivables (net of recoveries) of $3.4 million, $5.7 million and $0.3 million, respectively. In addition, we recorded a $5.9 million decrease in the allowance in fiscal 2005 from the completion of the purchase price allocation for the London Bridge acquisition, the disposition of Phoenix and currency translation.

6.   Other Investments

As a result of our acquisition of HNC Software, Inc. (“HNC”) in August 2002, we obtained investments accounted for using the cost method including an approximate 6.0% ownership interest in Open Solutions, Inc. (“OSI”), a developer of client/server core data processing solutions for community banks and credit unions. In November 2003, OSI completed an initial public offering of its common stock, at which time we began accounting for it as a marketable equity security. In May 2004, we sold our investment in OSI for net proceeds of $14.1 million, which included a realized gain of $6.6 million ($4.0 million net of tax) that was included in other income, net, within the accompanying consolidated statement of income for fiscal 2004.

7.   Goodwill and Intangible Assets

Goodwill and intangible assets with indefinite lives are tested for impairment at least annually or more frequently if impairment indicators arise. Our other intangible assets have definite lives and are being amortized using the straight-line method or based on the forecasted cash flows associated with the assets over their estimated useful lives.

As prescribed by SFAS No. 142, Goodwill and Other Intangible Assets, we have determined that our reporting units are the same as our reportable segments (see Note 16). We selected the fourth quarter to perform our annual goodwill impairment test, and determined that goodwill was not impaired as of July 1, 2006 and 2005.

Balance at September 30, 2006	$	542,549		$	88,254	$	12,451	$	51,908		$	695,162

During fiscal 2005, we adjusted our preliminary allocation of the London Bridge and Diversified HealthCare Services, Inc. purchase prices. The London Bridge adjustment was primarily attributable to an $8.0 million adjustment made to increase accounts receivable to its net realizable value, which was partially offset by a $2.6 million reduction in deferred tax assets to reflect a revision of certain estimates made. The Diversified HealthCare Services adjustment resulted in a $4.1 million increase in goodwill due to additional payments made to the selling shareholders as the result of achievement of revenue targets.

9.   Convertible Notes

Senior Notes

In August 2003, we issued $400.0 million of Senior Notes that mature on August 15, 2023. The Senior Notes become convertible into shares of Fair Isaac common stock, subject to the conditions described below, at an initial conversion price of $43.9525 per share, subject to adjustments for certain events. The initial conversion price is equivalent to a conversion rate of approximately 22.7518 shares of Fair Isaac common stock per $1,000 principal amount of the Senior Notes. Holders may surrender their Senior Notes for conversion, if any of the following conditions is satisfied: (i) prior to August 15, 2021, during any fiscal quarter, if the closing price of our common stock for at least 20 trading days in the 30 consecutive trading day period ending on the last day of the immediately preceding fiscal quarter is more than 120% of the conversion price per share of our common stock on the corresponding trading day; (ii) at any time after the closing sale price of our common stock on any date after August 15, 2021 is more than 120% of the then current conversion price; (iii) during the five consecutive business day period following any 10 consecutive trading day period in which the average trading price of a Senior Note was less than 98% of the average sale price of our common stock during such 10 trading day period multiplied by the applicable conversion rate; provided, however, if, on the day before the conversion date, the closing price of our common stock is greater than 100% of the conversion price but less than or equal to 120% of the conversion price, then holders converting their notes may receive, in lieu of our common stock based on the applicable conversion rate, at our option, cash or common stock with a value equal to 100% of the principal amount of the notes on the conversion date; (iv) if we have called the Senior Notes for redemption; or (v) if we make certain distributions to holders of our common stock or we enter into specified corporate transactions. The conversion price of the Senior Notes will be adjusted upon the occurrence of certain dilutive events as described in the indenture, which include but are not limited to: (i) dividends, distributions, subdivisions, or combinations of our common stock; (ii) issuance of rights or warrants for the purchase of our common stock under certain circumstances; (iii) the distribution to all or substantially all holders of our common stock of shares of our capital stock, evidences of indebtedness, or other non-cash assets, or rights or warrants; (iv) the cash dividend or distribution to all or substantially all holders of our common stock in excess of certain levels; and (v) certain tender offer activities by us or any of our subsidiaries.

The Senior Notes are senior unsecured obligations of Fair Isaac and rank equal in right of payment with all of our unsecured and unsubordinated indebtedness. The Senior Notes are effectively subordinated to all of our existing and future secured indebtedness and existing and future indebtedness and other liabilities of our subsidiaries. The Senior Notes bear regular interest at an annual rate of 1.5%, payable on August 15 and February 15 of each year until August 15, 2008. Beginning August 15, 2008, regular interest will accrue at the rate of 1.5%, and be due and payable upon the earlier to occur of redemption, repurchase, or final maturity. In addition, the Senior Notes bear contingent interest during any six-month period from August 15 to February 14 and from February 15 to August 14, commencing with the six-month period beginning August 15, 2008, if the average trading price of the Senior Notes for the five trading day period immediately preceding the first day of the applicable six-month period equals 120% or more of the sum of the principal amount of, plus accrued and unpaid regular interest on, the Senior Notes. The amount of contingent interest payable on the Senior Notes in respect of any six-month period will equal 0.25% per annum of the average trading price of the Senior Notes for the five trading day period immediately preceding such six-month period.

We may redeem for cash all or part of the Senior Notes on and after August 15, 2008, at a price equal to 100% of the principal amount of the Senior Notes, plus accrued and unpaid interest. Holders may require us to repurchase for cash all or part of the $400.0 million of Senior Notes on August 15, 2007, August 15, 2008, August 15, 2013 and August 15, 2018, or upon a change in control, at a price equal to 100% of the principal amount of the Senior Notes being repurchased, plus accrued and unpaid interest.

On March 31, 2005, we completed an exchange offer for the Senior Notes, whereby holders of approximately 99.9% of the total principal amount of our Senior Notes exchanged their existing securities for new 1.5% Senior Convertible Notes, Series B (“New Notes”). The terms of the New Notes are similar to the terms of the Senior Notes described above, except that: (i) upon conversion, we will pay holders cash in an amount equal to the lesser of the principal amount of such notes and the conversion value of such notes, and to the extent such conversion value exceeds the principal amount of the notes, the remainder of the conversion obligation in cash or common shares or combination thereof; (ii) in the event of a change of control, we may be required in certain circumstances to pay a make-whole premium on the New Notes converted in connection with the change of control and (iii) if the conversion condition in the first clause (iii) in the third paragraph preceding this paragraph is triggered and the closing price of our common stock is greater than 100% of the conversion price but less than or equal to 120% of the conversion price, the holders converting New Notes shall receive cash with a value equal to 100% of the principal amount of New Notes on the conversion date.

The fair value of the Senior Notes at September 30, 2006 and 2005, as determined based upon quoted market prices, was $407.0 million and $446.5 million, respectively.

Subordinated Notes

In connection with our acquisition of HNC, we assumed $150.0 million of 5.25% Convertible Subordinated Notes (the “Subordinated Notes”) that were to mature on September 1, 2008. In July 2004, our Board of Directors approved the cash redemption of all of the outstanding Subordinated Notes at a redemption price equal to 102.625% of the $150.0 million principal amount of the Subordinated Notes, pursuant to the redemption criteria in the indenture. In September 2004, we redeemed all of the outstanding Subordinated Notes for $153.9 million, which resulted in the recognition of a loss on redemption of $11.1 million, representing the excess of the redemption cost over the carrying amount of the notes upon redemption.

10.   Restructuring and Acquisition-Related Expenses

During fiscal 2004, in connection with our acquisition of London Bridge, we completed a plan to exit certain London Bridge office space and reduce London Bridge staff. Accordingly, we recorded a lease exit accrual of $3.2 million, representing future cash obligations under the leases, net of estimated sublease income, and we recorded an employee separation accrual of $1.2 million. These amounts were recorded to goodwill in connection with our preliminary allocation of the London Bridge purchase price.

During fiscal 2004, we completed a plan to exit certain office space acquired in connection with our fiscal 2003 acquisition of NAREX Inc., and accordingly, recorded a lease exit accrual and additional goodwill of $1.7 million. Also during fiscal 2004, we recorded a $0.5 million charge related to the closure of a Fair Isaac office facility upon relocating those operations into an acquired London Bridge office facility. This amount is recorded in restructuring and acquisition-related expense in the accompanying consolidated statements of income.

During fiscal 2005, in connection with our acquisition of Braun, we recorded a $4.5 million lease exit accrual and we also completed a plan to reduce Braun staff and accordingly recorded a $1.3 million employee separation accrual. These amounts were recorded to goodwill in connection with our allocation of the Braun purchase price. During fiscal 2005, we incurred an additional $1.2 million of lease exit costs related to our London Bridge acquisition. These amounts were recorded to goodwill in connection with our allocation of the Braun and London Bridge purchase prices.

During fiscal 2006, we vacated excess lease space primarily located in California and recorded a lease exit accrual of $13.0 million, representing future cash lease obligations, net of estimated sublease income. In connection with a restructuring initiative, we incurred charges of $5.1 million for severance costs associated with a reduction of 190 employees primarily in product management, delivery and development functions. Cash payments for the

majority of these severance costs were paid in fiscal 2006. We also recorded a $0.2 million gain in fiscal 2006 due to the adjustment of liabilities established for the exit of certain leased spaces.

The following table summarizes our restructuring and acquisition-related accruals associated with the above actions. The current portion and non-current portion was recorded in other accrued current liabilities and other long-term liabilities within the accompanying consolidated balance sheets.

During fiscal 2006, we recorded a $0.5 million gain from past rent paid that was refunded to us from the landlord. During fiscal 2006 and 2004, we wrote off deferred acquisition costs totaling $2.2 million and $0.7 million, respectively, in connection with abandoned acquisitions, consisting principally of third-party legal, accounting and other professional fees. These amounts are recorded in restructuring and acquisition-related expenses in the accompanying consolidated statements of income.

11.   Income Taxes

The provision for income taxes was as follows during fiscal 2006, 2005 and 2004:

	2006			2005			2004
	(In thousands)
Current:
Federal	$	44,832		$	40,213		$	47,789
State		8,346			5,771			6,034

		1,125			13,279			11,911
Total provision	$	55,706		$	59,540		$	66,027

The foreign provision was based on foreign pretax earnings (loss) of $3.8 million, $(9.8) million and $(7.5) million in fiscal 2006, 2005 and 2004, respectively.

During fiscal 2006, 2005 and 2004, we realized certain tax benefits related to nonqualified and incentive stock options in the amounts of $10.6 million, $12.7 million and $15.9 million, respectively, that were credited directly to paid-in-capital.

Deferred tax assets and liabilities at September 30, 2006 and 2005 were as follows:

Deferred tax assets, net	$	22,221		$	26,990

Based upon the level of historical taxable income and projections for future taxable income over the periods that the deferred tax assets will reverse, management believes it is more likely than not that we will realize the benefits of the deferred tax asset, net of the existing valuation allowance at September 30, 2006.

For fiscal 2006, the change in the valuation allowance was due to utilization of net operating losses (“NOL”) in the United Kingdom. The valuation allowance for deferred tax assets increased approximately $16.1 million in fiscal 2005. Approximately $11.3 million of this increase related to a valuation allowance established for a U.S. capital loss carryforward that was principally generated as a result of the sale of London Bridge Phoenix Software and for which realization of a tax benefit is uncertain prior to the expiration of the carryforward period. The balance of the increase in the valuation allowance principally related to an increase of deferred tax assets associated with foreign operations for which realization also remains uncertain.

For fiscal 2006, the change in the balance of the NOL carryforward was due to utilization. We acquired NOL and research credit carryforwards in connection with our acquisitions of Braun, London Bridge, and HNC in fiscal 2005, 2004 and 2002, respectively. As of September 30, 2006, we had available U.S. federal, state and foreign NOL carryforwards of approximately $74.5 million, $44.1 million and $32.3 million, respectively. We also have available U.S. federal and state research credit carryforwards of approximately $8.9 million and $7.8 million, respectively. The U.S. federal NOL carryforwards will expire at various dates beginning in fiscal 2010 through

79

FAIR ISAAC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Years Ended September 30, 2006, 2005 and 2004

fiscal 2024, if not utilized. The state NOL carryforwards will begin to expire in fiscal 2007 through fiscal 2024, if not utilized. The U.S. federal research credit carryforwards will begin to expire in fiscal 2007 through 2022, if not utilized. Utilization of the U.S. federal and state NOL and research credit carryforwards are subject to an annual limitation due to the “change in ownership” provisions of the Internal Revenue Code of 1986 (the “Code”), as amended, and similar state provisions. In addition, certain limitations apply to our ability to utilize the foreign NOL carryforwards.

We are currently under examination by the IRS for tax returns filed for fiscal 1998 through 2004 and by the California Franchise Tax Board for fiscal 1998 through 2002. Although the final outcome of these examinations remains unknown, we have reserved for potential adjustments that may result from the examinations and believe the final resolution will not have a material effect on our results of operations. We assess the adequacy of these reserves in each reporting period based on then-current information. Adjustments to the reserves are recognized in our income tax provision in the period in which such determination is made.

The reconciliation between the U.S. federal statutory income tax rate of 35% and our effective tax rate is shown below for fiscal 2006, 2005 and 2004:

	2006			2005			2004

Other		2,526			1,918			1,508
Recorded income tax provision	$	55,706		$	59,540		$	66,027

Our effective tax rate in fiscal 2006 was impacted by three major items. First, the effective rate was impacted by the recognition of $1.0 million of tax benefit from the adoption of Internal Revenue Code (“IRC”) §199. IRC §199 provides a special income tax deduction for income from domestic production activities. Second, the effective rate was impacted by our foreign operations reporting income in fiscal 2006 as opposed to losses as reported in previous years. Finally, the effective rate was impacted by the non-recurring discrete tax benefits recognized in fiscal 2005. Our effective tax rate in fiscal 2005 was impacted by the recognition of $10.6 million of tax benefits from the implementation of tax planning strategies that related to prior years. These benefits were determined in conjunction with tax studies we performed with outside advisors that identified an additional $7.1 million of U.S. federal and $3.5 million of state tax credits and other deductions related to prior years’ tax return filings. The additional amounts relate to research credits, extraterritorial income exclusion, and state apportionment methodology. The tax benefits recognized reflect our estimate of the effect of amended tax returns filed for fiscal 1998 through 2004.

12.   Earnings Per Share

The following reconciles the numerators and denominators of basic and diluted earnings per share (“EPS”) during fiscal 2006, 2005 and 2004:

	2006		2005		2004
	(In thousands, except per share data)
Numerator for basic earnings per share — net income	$	103,486	$	134,548	$	102,788
Interest expense on Senior Notes, net of tax		4		2,508		4,918
Numerator for diluted earnings per share	$	103,490	$	137,056	$	107,706
Denominator — shares:
Basic weighted-average shares		63,579		66,556		69,933
Effect of dilutive securities		1,546		7,028		12,199
Diluted weighted-average shares		65,125		73,584		82,132
Earnings per share:
Basic	$	1.63	$	2.02	$	1.47
Diluted	$	1.59	$	1.86	$	1.31

The computation of diluted EPS for fiscal 2006, 2005 and 2004 excludes options to purchase approximately 3,194,000, 3,211,000 and 3,051,000 shares of common stock, respectively, because the options’ exercise prices exceeded the average market price of our common stock in these fiscal years and their inclusion would be antidilutive. The computation of diluted EPS for fiscal 2004 excludes approximately 3,800,000 shares of common stock issuable upon conversion of our Subordinated Notes, as the inclusion of such shares would have been antidilutive. On October 13, 2004, the FASB ratified the consensus reached by the EITF with respect to Issue No. 04-8, The Effect of Contingently Convertible Instruments on Diluted Earnings Per Share. This consensus requires us to consider all instruments with contingent conversion features that are based on the market price of our own stock in our diluted earnings per share calculation, regardless of whether the market price conversion triggers are then met. The computation for diluted EPS for fiscal 2005 and 2004 includes approximately 4,529,000 and 9,101,000 shares of common stock, respectively, issuable upon conversion of our Senior Notes. Effective with the completed exchange offer on March 31, 2005, the dilutive effect of the New Notes are calculated using the treasury stock method.

13.   Stockholders’ Equity

Common Stock

From time to time, we repurchase our common stock in the open market pursuant to programs approved by our Board of Directors. During fiscal 2006, 2005 and 2004, we expended $256.5 million, $328.5 million and $101.1 million, respectively, in connection with our repurchase of common stock under such programs. In August 2006, our Board of Directors approved a new common stock repurchase program that allows us to purchase shares of our common stock up to an aggregate cost of $250.0 million. Through September 30, 2006, we had repurchased 2,369,428 shares of our common stock under this program for an aggregate cost of $85.3 million. See Note 20 regarding a new stock repurchase program approved subsequent to September 30, 2006.

We paid quarterly dividends on common stock of two cents per share, or eight cents per year, during each of fiscal 2006, 2005 and 2004.

Stockholder Rights Plan

We maintain a stockholder rights plan pursuant to which one right to purchase preferred stock was distributed for each outstanding share of common stock held of record on August 21, 2001. Since this distribution, all newly issued shares of common stock have been accompanied by a preferred stock purchase right. In general, the rights will become exercisable and trade independently from the common stock if a person or group acquires or obtains the right to acquire 15 percent or more of the outstanding shares of common stock or commences a tender or exchange offer that would result in that person or group acquiring 15 percent or more of the outstanding shares of common stock, either event occurring without the consent of the Board of Directors. Each right represents a right to purchase Series A Participating Preferred Stock in an amount and at an exercise price that are subject to adjustment. The

person or group who acquired 15 percent or more of the outstanding shares of common stock would not be entitled to make this purchase. The rights will expire in August 2011, or they may be redeemed by the Company at a price of $0.001 per right prior to that date.

14.   Employee Benefit Plans

Defined Contribution Plans

We sponsor a Fair Isaac 401(k) plan for eligible employees. Under this plan, eligible employees may contribute up to 25% of compensation, not to exceed statutory limits. We also provide a company matching contribution. Investment in Fair Isaac common stock is not an option under this plan. Our contributions into all 401(k) plans, including former acquired company sponsored plans that have since merged into the Fair Isaac 401(k) plan or have been frozen, totaled $7.4 million, $6.8 million and $6.5 million during fiscal 2006, 2005 and 2004, respectively.

Employee Incentive Plans

We maintain various employee incentive plans for the benefit of eligible employees, including officers. The awards generally are based on the achievement of certain financial and performance objectives subject to the discretion of management. Total expenses under our employee incentive plans were $8.6 million, $6.9 million and $5.2 million during fiscal 2006, 2005 and 2004, respectively.

15.   Stock-Based Employee Benefit Plans

Description of Stock Option and Share Plans

We maintain the 1992 Long-term Incentive Plan (the “1992 Plan”) under which we may grant stock options, stock appreciation rights, restricted stock, restricted stock units and common stock to officers, key employees and non-employee directors. Under the 1992 Plan, a number of shares equal to 4% of the number of shares of Fair Isaac common stock outstanding on the last day of the preceding fiscal year is added to the shares available under this plan each fiscal year, provided that the number of shares for grants of incentive stock options for the remaining term of this plan shall not exceed 5,062,500 shares. As of September 30, 2006, 832,157 shares remained available for grants under this plan. The 1992 Plan will terminate in February 2012. In November 2003, our Board of Directors approved the adoption of the 2003 Employment Inducement Award Plan (the “2003 Plan”). The 2003 Plan reserves 2,250,000 shares of common stock solely for the granting of inducement stock options and other awards, as defined, that meet the “employment inducement award” exception to the New York Stock Exchange’s listing standards requiring shareholder approval of equity-based inducement incentive plans. Except for the employment inducement award criteria, awards under the 2003 Plan will be generally consistent with those made under our 1992 Plan. As of September 30, 2006, 1,461,975 shares remained available for grants under this plan. The 2003 Plan shall remain in effect until terminated by the Board of Directors. We also maintain individual stock option plans for certain of our executive officers and the chairman of the board. There are no shares available for future grants under these plans.

Stock option awards granted during fiscal 2006 typically have a maximum term of seven years and vest ratably over four years. Stock option awards granted prior to October 1, 2005, typically have a maximum term of ten years and vest ratably over four years.

We assumed all outstanding stock options held by former employees and non-employee directors of HNC, who as of our acquisition date, held unexpired and unexercised stock option grants under the various HNC stock option plans. As of September 30, 2006, 1,324,593 shares remained available for future grant under these option plans.

Description of Employee Stock Purchase Plan

Under our Purchase Plan, we are authorized to issue up to 5,062,500 shares of common stock to eligible employees. Employees may have up to 10% of their base salary withheld through payroll deductions to purchase Fair Isaac common stock during semi-annual offering periods. The purchase price of the stock is the lower of 85% of (i) the fair market value of the common stock on the enrollment date (the first day of the offering period), or (ii) the fair market value on the exercise date (the last day of each offering period). Offering period means approximately six-month periods commencing (a) on the first trading day on or after January 1 and terminating on the last trading day in the following June, and (b) on the first trading day on or after July 1 and terminating on the last trading day in the following December.

A total of approximately 300,000, 298,000 and 268,000 shares of our common stock with a weighted average purchase price of $30.88, $29.12 and $27.68 per share were issued under the Purchase Plan during fiscal 2006, 2005 and 2004, respectively. At September 30, 2006, 3,559,000 shares remained available for issuance.

Description of Employee Stock Ownership Plan

We maintain a Non-U.S. Employee Stock Ownership Plan (“Non-U.S. ESOP”) that covers eligible employees working in the United Kingdom and contributions into the Non-U.S. ESOP are determined annually by our Board of Directors. There were no contributions into this plan during fiscal 2006, 2005 and 2004.

Impact of the Adoption of SFAS No. 123(R)

See Note 1 for a description of our adoption of SFAS No. 123(R) on October 1, 2005. The following table summarizes the share-based compensation expense included in operating expense captions that we recorded within the accompanying consolidated statements of income for fiscal 2006, 2005 and 2004:

	2006		2005		2004
	(In thousands)
Cost of revenues	$	10,970	$	703	$	120
Research and development		6,435		166		169
Selling, general and administrative		24,680		2,058		1,280
	$	42,085	$	2,927	$	1,569

We recorded $41.1 million in pre-tax share-based compensation expense for stock options and purchases under the Purchase Plan and $1.0 million in share-based compensation expense for restricted stock awards in fiscal 2006. The total tax benefit related to this share-based compensation expense was $15.4 million in fiscal 2006. Share-based compensation expense reduced diluted earnings per share by $0.41 in fiscal 2006. As of September 30, 2006, there was $70.4 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under all equity compensation plans. Total unrecognized compensation cost will be adjusted for future changes in estimated forfeitures. We expect to recognize that cost over a weighted average period of 2.0 years.

SFAS No. 123(R) also requires companies to calculate an initial “pool” of excess tax benefits available at the adoption date to absorb any tax deficiencies that may be recognized under SFAS No. 123(R). The pool includes the net excess tax benefits that would have been recognized if we had adopted SFAS No. 123 for recognition purposes on its effective date. We have elected to calculate the pool of excess tax benefits under the alternative transition method described in FASB Staff Position 123(R)-3, Transition Election Related to Accounting for Tax Effects of Share-Based Payment Awards, which also specifies the method we must use to calculate excess tax benefits reported on the statement of cash flows.

Prior to the adoption of SFAS No. 123(R), we presented all tax benefits for deductions resulting from the exercise of stock options as operating cash flows within our consolidated statements of cash flows. SFAS No. 123(R)requires the cash flows resulting from the tax benefits for tax deductions in excess of the compensation expense recorded for those options (excess tax benefits) to be classified as financing cash flows. Accordingly, the $7.1 million excess tax benefit that is classified as a financing cash inflow in the accompanying consolidated statements of cash flows in fiscal 2006 was classified as an operating cash inflow prior to the adoption of SFAS No. 123(R).

We received $64.2 million in cash from option exercises and issuances of stock under the Purchase Plan in fiscal 2006. The actual tax benefit that we realized for the tax deductions from option exercises of the share-based payment arrangements totaled $11.5 million for that period.

Due primarily to our ongoing program of repurchasing shares on the open market, we had approximately 29.5 million treasury shares at September 30, 2006. We satisfy stock option exercises and Purchase Plan issuances from this pool of treasury shares.

Determining Fair Value

We estimate the fair value of options granted using the Black-Scholes option valuation model. We estimate the volatility of our common stock at the date of grant based on a combination of the implied volatility of publicly traded options on our common stock and our historical volatility rate, consistent with SFAS No. 123(R) and Securities and Exchange Commission Staff Accounting Bulletin No. 107 (“SAB 107”). Our decision to use implied volatility was based upon the availability of actively traded options on our common stock and our assessment that implied volatility is more representative of future stock price trends than historical volatility. We estimate expected term consistent with the simplified method identified in SAB 107 for share-based awards granted during the fiscal year ended September 30, 2006. We elected to use the simplified method as we changed the contractual life for share-based awards from ten to seven years starting in fiscal 2006. The simplified method calculates the expected term as the average of the vesting and contractual terms of the award. Previously, we estimated expected term based on historical exercise patterns. The dividend yield assumption is based on historical dividend payouts. The risk-free interest rate assumption is based on observed interest rates appropriate for the term of our employee options. We use historical data to estimate pre-vesting option forfeitures and record share-based compensation expense only for those awards that are expected to vest. For options granted, we amortize the fair value on a straight-line basis over the vesting period of the options.

The weighted average fair value of options granted during fiscal 2006, 2005 and 2004 were $13.79, $13.61, and $14.75, respectively. The aggregate intrinsic value of options outstanding at September 30, 2006 was calculated as the difference between the exercise price of the underlying options and the market price of our common stock for the 9.8 million shares that had exercise prices that were lower than the $36.57 market price of our common stock at September 30, 2006. The total intrinsic value of options exercised during fiscal 2006, 2005 and 2004 was $35.8 million, $55.8 million and $41.8 million, respectively, determined as of the date of exercise.

16.   Segment Information

We are organized into the following four reportable segments, to align with the internal management of our worldwide business operations based on product and service offerings:

•  Strategy Machine^tm Solutions.  These are pre-configured EDM applications designed for a specific type of business problem or process, such as marketing, account origination, customer management, fraud and medical bill review. This segment also includes our myFICO solutions for consumers.

•  Scoring Solutions.  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 lenders directly.

Years Ended September 30, 2006, 2005 and 2004

•  Professional Services.  Through our professional services, we tailor our EDM products to our clients’ environments, and we design more effective decisioning environments for our clients. This segment includes revenues from custom engagements, business solution and technical consulting services, systems integration services, and data management services.

•  Analytic Software Tools.  This segment is composed of software tools that clients can use to create their own custom EDM applications.

Our Chief Executive Officer evaluates segment financial performance based on segment revenues and operating income. Segment operating expenses consist of direct and indirect costs principally related to personnel, facilities, consulting, travel, depreciation and amortization. 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 share-based compensation expense, restructuring and acquisition-related expense 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 and amortization amounts are allocated to the segments from their internal cost centers as described above.

During fiscal 2006, 2005 and 2004, no individual customer contributed to 10% or more of our total revenues, however, we derive a substantial portion of our revenues from our contracts with the three major credit reporting agencies, TransUnion, Equifax and Experian. Revenues collectively generated by agreements with these customers accounted for 18% of our total revenues in fiscal 2006. At September 30, 2006 and 2005, no individual customer contributed to 10% or more of total consolidated receivables.

Our property and equipment, net, on a geographical basis are summarized below at September 30, 2006 and 2005. At September 30, 2006 and 2005, no individual country outside of the United States accounted for 10% or more of total consolidated net property and equipment.

We occupy the majority of our facilities under non-cancelable operating leases with lease terms in excess of one year. Such facility leases generally provide for annual increases based upon the Consumer Price Index or fixed increments. Rent expense under operating leases, including month-to-month leases, totaled $28.2 million, $28.4 million and $26.4 million during fiscal 2006, 2005 and 2004, respectively.

We are also a party to a management agreement with twenty of our executives providing for certain payments and other benefits in the event of a qualified change in control of Fair Isaac, coupled with a termination of the officer during the following year.

18.   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 believe that none of these aforementioned claims or actions will result in a material adverse impact to our consolidated results of operations, liquidity or financial condition. However, the amount or range of any potential liabilities associated with these claims and actions, if any, cannot be determined with certainty. Set forth below is additional detail concerning certain ongoing litigation.

Customer Claims

We are party to two separate lawsuits involving two different customers who have asserted that our performance under professional services contracts with such customers has caused them to incur damages. One customer’s lawsuit is pending in the United States District Court for the Central District of California, and the other is pending as a counterclaim to a collection lawsuit that we commenced in the United States District Court for the Southern District of Texas. The customers in these matters have claimed damages in excess of $10 million. We believe that these claims are without merit, and we intend to contest them vigorously. We also believe that the resolution of these claims will not result in a material adverse impact to our consolidated financial condition.

Putative Consumer Class Action Lawsuits

We are a defendant in a lawsuit captioned as Robbie Hillis v. Equifax Consumer Services, Inc. and Fair Isaac, Inc., which is pending in the U.S. District Court for the Northern District of Georgia. The plaintiff claims that the defendants have jointly sold the Score Power^® credit score product in violation of certain procedural requirements under the Credit Repair Organizations Act (“CROA”), and in violation of the antifraud provisions of that statute. The plaintiff also claims that the defendants are “credit repair organizations” under CROA. The plaintiff is seeking certification of a class on behalf of all individuals who purchased products containing Score Power from the defendants in the five year period prior to the filing of the Complaint on November 14, 2004. The plaintiff is seeking unspecified damages, attorneys’ fees and costs. We believe that the claims in this lawsuit are without merit, and we have denied any liability or wrongdoing and have denied that class certification is appropriate. We are vigorously contesting this matter. The plaintiff brought a motion for class certification and a motion for summary judgment in his favor and against the defendants. We opposed, and the Court denied, both of the plaintiff’s motions. The plaintiff has brought a motion asking the Court to reconsider its prior ruling. That motion is pending. We believe that the resolution of this claim will not result in a material adverse impact to our consolidated financial condition.

We are a defendant in a lawsuit captioned as Christy Slack v. Fair Isaac Corporation and MyFICO Consumer Services, Inc., which is pending in the United States District Court for the Northern District of California. As in the Hillis matter, the plaintiff is claiming that the defendants violated certain procedural requirements of CROA, and violated the antifraud provisions of CROA, with respect to the sale of credit score products on our myFICO.com website. The plaintiff also claims that the defendants violated the California Credit Services Act (the “CSA”) and were unjustly enriched. The plaintiff has sought certification of a class on behalf of all individuals who purchased credit score products from us on the myFICO.com website in the five year period prior to the filing of the Complaint on January 18, 2005. Plaintiff seeks unspecified damages, attorneys’ fees and costs. We believe that the claims in this lawsuit are without merit and we have denied any liability or wrongdoing and have denied that class certification is appropriate. We are vigorously contesting this matter. We brought a motion to dismiss the plaintiff’s claims. The Court granted our motion, in part, by dismissing certain of the plaintiff’s claims under the CSA. The plaintiff has brought motions for summary judgment and for class certification. We have opposed both motions. The Court has not yet ruled on the plaintiff’s motions. We believe that the resolution of this claim will not result in a material adverse impact to our consolidated financial condition.

Braun Consulting, Inc.

Braun (which we acquired in November 2004) was a defendant in a lawsuit filed on November 26, 2001, in the United States District Court for the Southern District of New York (Case No. 01 CV 10629) that alleges violations of federal securities laws in connection with Braun’s initial public offering in August 1999. This lawsuit is among approximately 300 coordinated putative class actions against certain issuers, their officers and directors, and underwriters with respect to such issuers’ initial public offerings. As successor in interest to Braun, we have entered into a Stipulation and Agreement of Settlement, pursuant to a Memorandum of Understanding, along with most of the other defendant issuers in this coordinated litigation, whereby such issuers and their officers and directors will be dismissed with prejudice, subject to the satisfaction of certain conditions, including, among others, approval of the court. Under the terms of this agreement, we will not pay any amount of the settlement.

19.   Guarantees

In the ordinary course of business, we are not subject to potential obligations under guarantees that fall within the scope of FASB Interpretation (“FIN”) No. 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others, except for standard indemnification and warranty provisions that are contained within many of our customer license and service agreements and certain supplier agreements, including underwriter agreements, as well as standard indemnification agreements that we

91

FAIR ISAAC CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
Years Ended September 30, 2006, 2005 and 2004

have executed with certain of our officers and directors, and give rise only to the disclosure requirements prescribed by FIN No. 45. In addition, under previously existing accounting principles generally accepted in the United States of America, we continue to monitor the conditions that are subject to the guarantees and indemnifications to identify whether it is probable that a loss has occurred, and would recognize any such losses under the guarantees and indemnifications when those losses are estimable.

Indemnification and warranty provisions contained within our customer license and service agreements and certain supplier agreements are generally consistent with those prevalent in our industry. The duration of our product warranties generally does not exceed 90 days following delivery of our products. We have not incurred significant obligations under customer indemnification or warranty provisions historically and do not expect to incur significant obligations in the future. Accordingly, we do not maintain accruals for potential customer indemnification or warranty-related obligations. The indemnification agreements that we have executed with certain of our officers and directors would require us to indemnify such officers and directors in certain instances. We have not incurred obligations under these indemnification agreements historically and do not expect to incur significant obligations in the future. Accordingly, we do not maintain accruals for potential officer or director indemnification obligations. The maximum potential amount of future payments that we could be required to make under the indemnification provisions in our customer license and service agreements, and officer and director agreements is unlimited.

20.   Subsequent Events

Credit Agreement

In October 2006, we entered into a five-year $300 million unsecured revolving credit facility with a syndicate of banks. The credit facility may be increased to $500 million subject to certain terms and conditions. Proceeds from the credit facility can be used for capital requirements and general business purposes and may be used for the refinancing of existing debt, acquisitions and repurchases 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 and (b) the Federal Funds rate plus 0.50% or (ii) LIBOR plus an applicable margin. The margin on LIBOR borrowings ranges from 0.30% to 0.55% and is determined based on our consolidated leverage ratio. In addition, we must pay utilization fees if borrowings and commitments under the credit facility exceed 50% of the total credit facility commitment, as well as facility fees. The credit facility contains certain restrictive covenants, including maintenance of consolidated leverage and fixed charge coverage ratios. The credit facility also contains covenants typical of unsecured facilities.

Stock Repurchase Program

In November 2006, our Board of Directors canceled the stock repurchase program originally approved in August 2006 for the purchase of $250 million in common stock and approved a new common stock repurchase program. The new repurchase program allows us to purchase up to an aggregate of $500 million in shares of our common stock in the open market or through negotiated transactions. During the period October 1, 2006, through December 1, 2006, we repurchased 3,342,500 shares of our common stock for an aggregate cost of $138.5 million.

Not applicable.

Item 9A.   Controls and Procedures

An evaluation was carried out under the supervision and with the participation of Fair Isaac’s management, including the Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of Fair Isaac’s disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of the end of the period covered by this annual report. Based on that evaluation, the CEO and CFO have concluded that Fair Isaac’s disclosure controls and procedures are effective to ensure that information required to be disclosed by Fair Isaac in reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms.

No change in Fair Isaac’s internal control over financial reporting was identified in connection with the evaluation required by Rule 13a-15(d) of the Exchange Act that occurred during the quarter ended September 30, 2006, that has materially affected, or is reasonably likely to materially affect, Fair Isaac’s internal control over financial reporting.

Management’s Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rules 13a-15(f). Under the supervision and with the participation of management, including our CEO and CFO, we conducted an evaluation of the effectiveness of our internal controls over financial reporting based on the framework in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this evaluation management has concluded that our internal control over financial reporting was effective as of September 30, 2006.

Our management’s assessment of the design and effectiveness of our internal control over financial reporting as of September 30, 2006, has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which is included herein.

Our management, including our CEO and CFO, does not expect that our disclosure controls or our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM ON INTERNAL
CONTROL OVER FINANCIAL REPORTING

To the Board of Directors and Stockholders of

Fair Isaac Corporation

Minneapolis, Minnesota

We have audited management’s assessment, included in the accompanying Management’s Report on Internal Control Over Financial Reporting, that Fair Isaac Corporation and subsidiaries (the “Company”) maintained effective internal control over financial reporting as of September 30, 2006, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management’s assessment and an opinion on the effectiveness of the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management’s assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed by, or under the supervision of, the company’s principal executive and principal financial officers, or persons performing similar functions, and effected by the company’s board of directors, management, and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America (“generally accepted accounting principles”). A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion or improper management override of controls, material misstatements due to error or fraud may not be prevented or detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial reporting to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, management’s assessment that the Company maintained effective internal control over financial reporting as of September 30, 2006, is fairly stated, in all material respects, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of September 30, 2006, based on the criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended September 30, 2006 of the Company and our report dated December 8, 2006 expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the Company’s adoption of a new accounting standard.
