Organization, Consolidation and Presentation of Financial Statements [Abstract]
THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations IAC today consists of category leading businesses, including Dotdash Meredith, Angi Inc. and Care.com, among others ranging from early stage to established businesses. As used herein, "IAC," the "Company," "we," "our," "us" and other similar terms refer to IAC Inc. and its subsidiaries (unless the context requires otherwise). Basis of Presentation The Company prepares its consolidated financial statements (referred to herein as "financial statements") in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP"). The financial statements include the accounts of the Company, all entities that are wholly-owned by the Company and all entities in which the Company has a controlling financial interest. All intercompany transactions and balances between and among the Company and its subsidiaries have been eliminated. The unaudited interim financial statements have been prepared in accordance with GAAP for interim financial information and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, they do not include all of the information and notes required by GAAP for complete annual financial statements. In the opinion of management, the unaudited interim financial statements include all normal recurring adjustments considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The unaudited interim financial statements should be read in conjunction with the annual audited financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2022. Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of assets and liabilities. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates, judgments and assumptions, including those related to: the fair values of cash equivalents and marketable debt and equity securities; the carrying value of accounts receivable, including the determination of the allowance for credit losses; the determination of the customer relationship period for certain costs to obtain a contract with a customer; the recoverability of right-of-use assets ("ROU assets"); the useful lives and recoverability of capitalized software, equipment, buildings and leasehold improvements and definite-lived intangible assets; the recoverability of goodwill and indefinite-lived intangible assets; the fair value of equity securities without readily determinable fair values; the fair value of interest rate swaps; contingencies; the fair value of acquisition-related contingent consideration arrangements; unrecognized tax benefits; the liability for potential refunds and customer credits; the valuation allowance for deferred income tax assets; pension and postretirement benefit expenses, including actuarial assumptions regarding discount rates, expected returns on plan assets, inflation and healthcare costs; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates, judgments and assumptions on historical experience, its forecasts and budgets and other factors that the Company considers relevant. Interest Rate Swaps In March 2023, Dotdash Meredith entered into interest rate swaps for a total notional amount of $350 million, which synthetically converted a portion of the Dotdash Meredith Term Loan B from floating rate to fixed rate to manage interest rate risk exposure beginning on April 3, 2023. Dotdash Meredith designated the interest rate swaps as cash flow hedges and applies hedge accounting to these contracts in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification 815, Derivatives and Hedging. As cash flow hedges, the interest rate swaps are recognized at fair value on the balance sheet as either assets or liabilities, with the changes in fair value recorded in "Accumulated other comprehensive loss" in the balance sheet and reclassified into “Interest expense” in the statement of operations in the periods in which the interest rate swaps affect earnings. Dotdash Meredith assessed hedge effectiveness at the time of entering into these agreements and determined these interest rate swaps are expected to be highly effective. Dotdash Meredith evaluates the hedge effectiveness of the interest rate swaps quarterly, or more frequently, if necessary, by verifying (i) that the critical terms of the interest rate swaps continue to match the critical terms of the hedged interest payments and (ii) that it is probable the counterparties will not default. If the two requirements are met, the interest rate swaps are determined to be effective and all changes in the fair value of the interest rate swaps are recorded in "Accumulated other comprehensive loss." The cash flows related to interest settlements of the hedged monthly interest payments are classified as operating activities in the statement of cash flows, consistent with the interest expense on the related Dotdash Meredith Term Loan B. See "Note 4—Long-term Debt" for additional information. General Revenue Recognition The Company accounts for a contract with a customer when it has approval and commitment from all parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to the Company's customers and in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services or goods. From January 1, 2020 through December 31, 2022, Services recorded revenue on a gross basis. Effective January 1, 2023, Angi Inc. modified the Services terms and conditions so that the service professional, rather than Angi Inc., has the contractual relationship with the consumer to deliver the service and Angi Inc.'s performance obligation to the consumer is to connect them with the service professional. This change in contractual terms requires revenue to be reported as the net amount of what is received from the consumer after deducting the amounts owed to the service professional providing the service effective for all arrangements entered into after December 31, 2022. There is no impact to operating loss or Adjusted EBITDA from this change in revenue recognition. For the three and six months ended June 30, 2022, if Services revenue were recorded on a net basis, revenue would have been reduced by $71.1 million and $122.8 million, respectively. The Company's disaggregated revenue disclosures are presented in "Note 6—Segment Information." Deferred Revenue Deferred revenue consists of payments that are received or are contractually due in advance of the Company's performance obligation. The Company’s deferred revenue is reported on a contract-by-contract basis at the end of each reporting period. The Company classifies deferred revenue as current when the remaining term or expected completion of its performance obligation is one year or less. The current and non-current deferred revenue balances were $160.8 million and $0.1 million, respectively, at June 30, 2023, and $157.1 million and $0.2 million, respectively, at December 31, 2022. During the six months ended June 30, 2023, the Company recognized $127.3 million of revenue that was included in the deferred revenue balance at December 31, 2022. During the six months ended June 30, 2022, the Company recognized $125.2 million of revenue that was included in the deferred revenue balance at December 31, 2021. The current and non-current deferred revenue balances were $165.5 million and $0.4 million, respectively, at December 31, 2021. Non-current deferred revenue is included in "Other long-term liabilities" in the balance sheet. Practical Expedients and Exemptions For contracts that have an original duration of one year or less, the Company uses the practical expedient available under FASB Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, applicable to such contracts and does not consider the time value of money. In addition, as permitted under the practical expedient available under ASU No. 2014-09, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is tied to sales-based or usage-based royalties, allocated entirely to unsatisfied performance obligations, or to a wholly unsatisfied promise accounted for under the series guidance and (iii) contracts for which the Company recognizes revenue at the amount which it has the right to invoice for services performed. Certain Risks and Concentrations—Services Agreement with Google (the "Services Agreement") The Company and Google are parties to an amended Services Agreement, which automatically renewed effective March 31, 2023 and now expires on March 31, 2025. The Company earns certain other advertising revenue from Google that is not attributable to the Services Agreement. A meaningful portion of the Company’s net cash from operating activities that it can freely access is attributable to revenue earned pursuant to the Services Agreement and other revenue earned from Google. For the three and six months ended June 30, 2023, total revenue earned from Google was $197.9 million and $370.8 million, respectively, representing 18% and 17%, respectively, of the Company's revenue. The revenue earned from the Services Agreement for the three and six months ended June 30, 2023, was $164.6 million and $303.3 million, respectively, representing 15% and 14%, respectively, of the Company's total revenue. For the three and six months ended June 30, 2022, total revenue earned from Google was $169.3 million and $362.7 million, respectively, representing 12% and 13%, respectively, of the Company's revenue. The revenue earned from the Services Agreement for the three and six months ended June 30, 2022, was $122.1 million and $269.3 million, respectively, representing 9% and 10%, respectively, of the Company's total revenue. The related accounts receivable totaled $68.8 million and $74.1 million at June 30, 2023 and December 31, 2022, respectively. The revenue attributable to the Services Agreement is earned by Ask Media Group and the Desktop business, which comprise the Search segment. For the three and six months ended June 30, 2023, revenue earned from the Services Agreement was $146.1 million and $266.4 million, respectively, within Ask Media Group and $18.4 million and $37.0 million, respectively, within the Desktop business. For the three and six months ended June 30, 2022, revenue earned from the Services Agreement was $97.6 million and $218.1 million, respectively, within Ask Media Group and $24.5 million and $51.2 million, respectively, within the Desktop business. The Services Agreement requires that the Company comply with certain guidelines promulgated by Google. Google may generally unilaterally update its policies and guidelines without advance notice. These updates may be specific to the Services Agreement or could be more general and thereby impact the Company as well as other companies. These policy and guideline updates have in the past and could in the future require modifications to, or prohibit and/or render obsolete certain of our products, services and/or business practices, which have been and could be costly to address or negatively impact revenue and have had and in the future could have an adverse effect on our financial condition and results of operations. As described below, Google has made changes to the policies under the Services Agreement and has also made industry-wide changes that have negatively impacted the Desktop business-to-consumer ("B2C") business. Google may make changes in the future that could impact the revenue earned from Google, including under the Services Agreement. As a result of certain industry-wide policy changes combined with increased enforcement by Google of policies under the Services Agreement in prior periods, the Company discontinued the introduction of new products in 2021. Therefore, the current B2C revenue stream relates solely to the then existing installed base of products. As a result, the revenue and profits of the B2C business have declined significantly and the Company expects that trend to continue. Recent Accounting Pronouncements There are no recently issued accounting pronouncements that are expected to have a material effect on the results of operations, financial condition or cash flows of the Company. Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation. In the fourth quarter of 2022, the Angi Inc. segment presentation was changed to reflect the following operating segments: (i) Ads and Leads, (ii) Services, (iii) Roofing and (iv) International (consisting of businesses in Europe and Canada). Angi Inc.'s financial information for all prior periods, including the three and six months ended June 30, 2022 included herein, has been recast to reflect this four operating segment presentation.
