Nature of Business	Nature of Business Fair Isaac Corporation Fair Isaac Corporation (NYSE: FICO) (together with its consolidated subsidiaries, the “Company,” which may also be referred to in this report as “we,” “us,” “our,” or “FICO”) is a leading applied analytics company. We were founded in 1956 on the premise that data, used intelligently, can improve business decisions. Today, FICO’s software and the widely used FICO® Score operationalize analytics, enabling thousands of businesses in more than 100 countries to uncover new opportunities, make timely decisions that matter, and execute them at scale. Most leading banks and credit card issuers rely on our solutions, as do insurers, retailers, telecommunications providers, automotive lenders, consumer reporting agencies, public agencies, and organizations in other industries. We also serve consumers through online services that enable people to access and understand their FICO® Scores — the standard measure in the U.S. of consumer credit risk — empowering them to increase financial literacy and manage their financial health. Principles of Consolidation and Basis of Presentation We have prepared the accompanying unaudited interim condensed consolidated financial statements in accordance with the instructions to Form 10-Q and the applicable accounting guidance. Consequently, we have not necessarily included all information and footnotes required for audited financial statements. In our opinion, the accompanying unaudited interim condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments, except as otherwise indicated) necessary for a fair presentation of our financial position and results of operations. These unaudited condensed consolidated financial statements and notes thereto should be read in conjunction with our audited consolidated financial statements and notes thereto presented in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023. The interim financial information contained in this report is not necessarily indicative of the results to be expected for any other interim period or for the entire fiscal year. The condensed consolidated financial statements include the accounts of FICO and its subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates We make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and the disclosures made in the accompanying notes. For example, we use estimates in determining the appropriate levels of various accruals; variable considerations included in the transaction price and standalone selling price of each performance obligation for our customer contracts; labor hours in connection with fixed-fee service contracts; the amount of our tax provision; and the realizability of deferred tax assets. We also use estimates in determining the remaining economic lives and carrying values of acquired intangible assets, property and equipment, and other long-lived assets. In addition, we use assumptions to estimate the fair value of reporting units and share-based compensation. Actual results may differ from our estimates. New Accounting Pronouncements Recent Accounting Pronouncements Adopted In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2021-08, “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” (“ASU 2021-08”). ASU 2021-08 requires an acquirer in a business combination to recognize and measure contract assets and contract liabilities from acquired contracts using the revenue recognition guidance under Accounting Standards Codification Topic 606, Revenue from Contacts with Customers, in order to align the recognition of a contract liability with the definition of a performance obligation. We adopted ASU 2021-08 in the first quarter of fiscal 2024 and the adoption did not have a significant impact on our condensed consolidated financial statements. Recent Accounting Pronouncements Not Yet Adopted In November 2023, the FASB issued ASU No. 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”). ASU 2023-07 expands annual and interim disclosure requirements for reportable segments, primarily through enhanced disclosures about significant segment expenses. The standard is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, which means that it will be effective for our annual periods beginning October 1, 2024, and our interim periods beginning October 1, 2025. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our disclosures within our consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” (“ASU 2023-09”). ASU 2023-09 requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as disaggregated information on income tax paid. The standard is effective for fiscal years beginning after December 15, 2024, which means that it will be effective for our fiscal years beginning October 1, 2025. Early adoption is permitted. We are currently evaluating the impact that the updated standard will have on our disclosures within our consolidated financial statements. In March 2024, the Securities and Exchange Commission (“SEC”) issued Final Rule Release No. 33-11275, “The Enhancement and Standardization of Climate-Related Disclosures for Investors.” This rule will require registrants to provide certain climate disclosures in their annual reports, including certain climate-related financial metrics in their audited financial statements. The rule is effective for large accelerated filers beginning with annual reports for the fiscal year beginning in 2025, which means that it will be effective for our fiscal years beginning October 1, 2025. We are currently evaluating the impact that the final rule will have on our disclosures within our consolidated financial statements. We do not expect that any other recently issued accounting pronouncements will have a significant effect on our consolidated financial statements.
