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 a variable rate to a 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 3—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 nine months ended September 30, 2022, if Services revenue were recorded on a net basis, revenue would have been reduced by $64.8 million and $187.5 million, respectively. The Company's disaggregated revenue disclosures are presented in " Note 5—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 $165.8 million and $0.1 million, respectively, at September 30, 2023 and $157.1 million and $0.2 million, respectively, at December 31, 2022. During the nine months ended September 30, 2023, the Company recognized $147.8 million of revenue that was included in the deferred revenue balance at December 31, 2022. During the nine months ended September 30, 2022, the Company recognized $145.4 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 nine months ended September 30, 2023, total revenue earned from Google was $180.3 million and $551.0 million, respectively, representing 16% and 17%, respectively, of the Company's revenue. The revenue earned from the Services Agreement for the three and nine months ended September 30, 2023, was $149.4 million and $452.7 million, respectively, representing 13% and 14%, respectively, of the Company's total revenue. For the three and nine months ended September 30, 2022, total revenue earned from Google was $161.6 million and $524.3 million , respectively, representing 12% and 13%, respectively, of the Company's revenue. The revenue earned from the Services Agreement for the three and nine months ended September 30, 2022, was $117.3 million and $386.6 million, respectively, representing 9% and 10%, respectively, of the Company's total revenue. The related accounts receivable totaled $57.4 million and $74.1 million at September 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 nine months ended September 30, 2023, revenue earned from the Services Agreement was $131.9 million and $398.3 million, respectively, within Ask Media Group and $17.5 million and $54.4 million, respectively, within the Desktop business . For the three and nine months ended September 30, 2022, revenue earned from the Services Agreement was $97.3 million and $315.4 million , respectively, within Ask Media Group and $20.0 million and $71.2 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 nine months ended September 30, 2022 included herein, has been recast to reflect this four operating segment presentation.

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS	FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS Marketable Securities At September 30, 2023 and December 31, 2022, the fair value of marketable securities are as follows: September 30, 2023 December 31, 2022 (In thousands) Marketable equity securities $ — $ 4,317 Available-for-sale marketable debt securities 173,717 235,056 Total marketable securities $ 173,717 $ 239,373 Marketable equity securities are carried at fair value. At December 31, 2022, the Company had two investments in marketable equity securities, other than the investment in MGM Resorts International ("MGM"), including one investment that was fully impaired in the first quarter of 2023 due to the investee declaring bankruptcy and another investment that was sold in the third quarter of 2023, resulting in a net pre-tax gain of $0.1 million. The Company recorded a net unrealized pre-tax loss of $0.3 million during the nine months ended September 30, 2023 and net unrealized pre-tax losses of $14.0 million and $8.3 million during the three and nine months ended September 30, 2022 for these investments, respectively. The realized and unrealized pre-tax gains and losses related to these investments are included in "Other income (expense), net" in the statement of operations. At September 30, 2023 and December 31, 2022, current available-for-sale marketable debt securities are as follows: September 30, 2023 December 31, 2022 Amortized cost Gross Unrealized Gains Gross Unrealized Losses Fair Value Amortized cost Gross Unrealized Gains Gross Unrealized Losses Fair Value (In thousands) Treasury discount notes $ 173,697 $ 20 $ — $ 173,717 $ 234,987 $ 75 $ (6) $ 235,056 Total available-for-sale marketable debt securities $ 173,697 $ 20 $ — $ 173,717 $ 234,987 $ 75 $ (6) $ 235,056 The contractual maturities of debt securities classified as current available-for-sale at September 30, 2023 and December 31, 2022 were within one year. There were no investments in available-for-sale marketable debt securities that had been in a continuous unrealized loss position for longer than twelve months at September 30, 2023 and December 31, 2022. Investment in MGM Resorts International September 30, 2023 December 31, 2022 (In thousands) Investment in MGM Resorts International $ 2,379,240 $ 2,170,182 At September 30, 2023, the Company owns 64.7 million shares of MGM, including a total of 5.7 million common shares purchased in the first and third quarters of 2022 for $244.3 million. Based on the number of MGM shares outstanding at June 30, 2023, the Company owns 18.3% of MGM. The fair value of the investment in MGM is remeasured each reporting period based upon MGM's closing stock price on the New York Stock Exchange on that last trading day in the reporting period and any unrealized pre-tax gains or losses are included in the statement of operations. For the three and nine months ended September 30, 2023, the Company recognized an unrealized pre-tax loss of $463.4 million and an unrealized pre-tax gain of $209.1 million on its investment in MGM, respectively. For the three and nine months ended September 30, 2022, the Company recorded an unrealized pre-tax gain of $42.5 million and an unrealized pre-tax loss of $970.1 million on its investment in MGM, respectively. The cumulative unrealized pre-tax gain at September 30, 2023 is $1.1 billion. A $2.00 increase or decrease in the share price of MGM would result in an unrealized gain or loss, respectively, of $129.4 million. At November 3, 2023, the fair value of the Company's investment in MGM was $2.5 billion . Long-term Investments Long-term investments consist of: September 30, 2023 December 31, 2022 (In thousands) Equity securities without readily determinable fair values $ 426,938 $ 323,530 Equity method investment 5,400 2,191 Total long-term investments $ 432,338 $ 325,721 In April 2023, the Company purchased additional preferred shares of Turo Inc. ("Turo"), a peer-to-peer car sharing marketplace, for $103.6 million, which is accounted for as an equity security without a readily determinable fair value, as the preferred shares are not common stock equivalents. Equity Securities without Readily Determinable Fair Values The following table presents a summary of unrealized pre-tax gains and losses recorded in "Other income (expense), net" in the statement of operations as adjustments to the carrying value of equity securities without readily determinable fair values held at September 30, 2023 and 2022. Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (In thousands) Upward adjustments (gross unrealized pre-tax gains) $ — $ 8,245 $ 2,227 $ 8,245 Downward adjustments including impairments (gross unrealized pre-tax losses) — — (373) (22,376) Total $ — $ 8,245 $ 1,854 $ (14,131) The cumulative upward and downward adjustments (including impairments) to the carrying value of equity securities without readily determinable fair values held at September 30, 2023 were $37.8 million and $104.0 million, respectively. Realized and unrealized pre-tax losses and gains for the Company's investments without readily determinable fair values for the three and nine months ended September 30, 2023 and 2022 are as follows: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (In thousands) Realized pre-tax (losses) gains, net, for equity securities sold during the period $ (109) $ 11,840 $ 69 $ 12,302 Unrealized pre-tax gains (losses), net, on equity securities held — 8,245 1,854 (14,131) Total pre-tax (losses) gains, net recognized $ (109) $ 20,085 $ 1,923 $ (1,829) All pre-tax losses and gains on equity securities without readily determinable fair values, realized and unrealized, are recognized in "Other income (expense), net" in the statement of operations. Fair Value Measurements The Company categorizes its financial instruments measured at fair value into a fair value hierarchy that prioritizes the inputs used in pricing the asset or liability. The three levels of the fair value hierarchy are: • Level 1: Observable inputs obtained from independent sources, such as quoted market prices for identical assets and liabilities in active markets. • Level 2: Other inputs, which are observable directly or indirectly, such as quoted market prices for similar assets or liabilities in active markets, quoted market prices for identical or similar assets or liabilities in markets that are not active and inputs that are derived principally from or corroborated by observable market data. The fair values of the Company's Level 2 financial assets are primarily obtained from observable market prices for identical underlying securities that may not be actively traded. Certain of these securities may have different market prices from multiple market data sources, in which case an average market price is used. • Level 3: Unobservable inputs for which there is little or no market data and require the Company to develop its own assumptions, based on the best information available in the circumstances, about the assumptions market participants would use in pricing the assets or liabilities. The following tables present the Company's financial instruments that are measured at fair value on a recurring basis: September 30, 2023 Quoted Market Significant Significant Total (In thousands) Assets: Cash equivalents: Money market funds $ 796,305 $ — $ — $ 796,305 Treasury discount notes — 161,729 — 161,729 Time deposits — 18,955 — 18,955 Marketable securities: Treasury discount notes — 173,717 — 173,717 Investment in MGM 2,379,240 — — 2,379,240 Other non-current assets: Warrant — — 45,525 45,525 Interest rate swaps (a) — 8,129 — 8,129 Total $ 3,175,545 $ 362,530 $ 45,525 $ 3,583,600 _____________________ (a) Interest rate swaps relate to the $350 million notional amount of Dotdash Meredith's Term Loan B and are included in "Other non-current assets" in the balance sheet. See " Note 1—The Company and Summary of Significant Accounting Policies " and " Note 3—Long-term Debt " for additional information. The fair value of interest rate swaps was determined using discounted cash flows derived from observable market prices, including swap curves, which are Level 2 inputs. December 31, 2022 Quoted Market Significant Significant Total (In thousands) Assets: Cash equivalents: Money market funds $ 862,829 $ — $ — $ 862,829 Treasury discount notes — 137,219 — 137,219 Time deposits — 16,018 — 16,018 Marketable securities: Marketable equity securities 4,317 — — 4,317 Treasury discount notes — 235,056 — 235,056 Investment in MGM 2,170,182 — — 2,170,182 Other non-current assets: Warrant — — 46,799 46,799 Total $ 3,037,328 $ 388,293 $ 46,799 $ 3,472,420 The following table presents the changes in the Company's financial instruments that are measured at fair value on a recurring basis using significant unobservable inputs (Level 3): Three Months Ended September 30, 2023 2022 Warrant Warrant (In thousands) Balance at July 1 $ 39,068 $ 122,145 Total net gains: Fair value adjustments included in earnings 6,457 8,467 Balance at September 30 $ 45,525 $ 130,612 Nine months ended September 30, 2023 2022 Warrant Warrant Contingent (In thousands) Balance at January 1 $ 46,799 $ 109,294 $ (612) Total net (losses) gains: Fair value adjustments included in earnings (1,274) 21,318 612 Balance at September 30 $ 45,525 $ 130,612 $ — Warrant As part of the Company's original investment in Turo preferred shares, the Company received a warrant that is recorded at fair value each reporting period using a Monte Carlo simulation model with any change included in "Other income (expense), net" in the statement of operations. The warrant is measured using significant unobservable inputs and is classified in the fair value hierarchy table as Level 3. The warrant is included in "Other non-current assets" in the balance sheet. Contingent Consideration Arrangements At September 30, 2023, the Company has no contingent consideration arrangements outstanding. In connection with the Meredith acquisition on December 1, 2021, the Company assumed a contingent consideration arrangement liability of $0.6 million, which was written off during the first quarter of 2022 due to a change in estimate of the liability related to this arrangement. Assets measured at fair value on a nonrecurring basis The Company's non-financial assets, such as goodwill, intangible assets, ROU assets, capitalized software, equipment, buildings and leasehold improvements, are adjusted to fair value only when an impairment is recognized. Such fair value measurements are based predominantly on Level 3 inputs. Goodwill During the third quarter of 2023 and second quarter of 2022, the Company reassessed the fair value of the Mosaic Group reporting unit (included in the Emerging & Other segment) and recorded goodwill impairments of $9.0 million and $86.7 million, respectively, as a result of the projected reduction in future revenue and profits from the business and lower trading multiples of a selected peer group of companies. The fair value of the Mosaic Group reporting unit was determined using both an income approach based on discounted cash flows ("DCF") and a market approach. Determining fair value using a DCF analysis requires the exercise of significant judgment with respect to several items, including the amount and timing of expected future cash flows and appropriate discount rates. The expected cash flows used in the DCF analyses were based on the most recent forecast for Mosaic Group. For years beyond the forecast period, the Mosaic Group estimates was based, in part, on forecasted growth rates. The discount rate used in the DCF analyses was 16% and was intended to reflect the risks inherent in the expected future cash flows of the Mosaic Group reporting unit. Determining fair value using a market approach considers multiples of financial metrics based on both acquisitions and trading multiples of a selected peer group of companies. From the comparable companies, a representative market multiple is determined, which is applied to financial metrics to estimate the fair value of the Mosaic Group reporting unit. To determine a peer group of companies for the Mosaic Group reporting unit, the Company considered companies relevant in terms of consumer use, monetization model, margin and growth characteristics, and brand strength operating in their respective markets. At September 30, 2023, Mosaic Group has goodwill of $144.6 million and the carrying value of this reporting unit approximates its fair value. Any subsequent declines in the fair value of Mosaic Group will result in additional goodwill impairment charges to the extent the carrying value exceeds the fair value. Intangible Asset During the third quarter of 2023, the Company determined that a projected reduction in future revenue related to a certain indefinite-lived trade name intangible asset in the Dotdash Meredith Digital segment was an indicator of possible impairment. Following the identification of the indicator, the Company updated its calculation of the fair value of the indefinite-lived intangible asset and recorded an impairment of $7.6 million. The impairment of indefinite-lived intangible assets is included in “Amortization of intangibles” in the statement of operations. The Company determines the fair value of indefinite-lived intangible assets using an avoided royalty DCF valuation analysis. Significant judgments inherent in this analysis include the selection of appropriate royalty and discount rates and estimating the amount and timing of expected future cash flows. The discount rate used in the DCF analysis was intended to reflect the risks inherent in the expected future cash flows generated by the intangible asset. The royalty rate used in the DCF analysis was based upon an estimate of the royalty rate that a market participant would pay to license the Company's trade names and trademarks. The discount rate used to value the trade name was 16% and the royalty rate was 8%. Following the impairment charge, the carrying value of this indefinite-lived intangible asset approximates its fair value. ROU Assets and Related Leasehold Improvements, Furniture and Equipment During the first quarter of 2023, Dotdash Meredith recorded impairment charges of $70.0 million related to certain unoccupied leased office space due to the continued decline in the commercial real estate market consisting of impairments of $44.7 million and $25.3 million of an ROU asset and related leasehold improvements, furniture and equipment, respectively. During the third quarter of 2022, Dotdash Meredith recorded impairment charges of $21.3 million related to the consolidation of certain leased spaces following the Meredith acquisition consisting of impairments of $14.3 million and $7.0 million of an ROU asset and related leasehold improvements, furniture and equipment, respectively. See " Note 6—Dotdash Meredith Restructuring Charges, Transaction-Related Expenses and Change-In-Control Payments " for additional information. The impairment charges related to ROU assets are included in "General and administrative expense" and the impairment charges related to leasehold improvements, furniture and equipment are included in "Depreciation" in the statement of operations. The impairment charges represent the amount by which the carrying value of the asset group exceeded its estimated fair value, calculated using a DCF approach using sublease market assumptions of the expected cash flows and discount rate. The impairment charges were allocated between the ROU assets and related leasehold improvements, furniture and equipment of the asset group based on their relative carrying values.

Interest payments are due at least quarterly through the terms of the Dotdash Meredith Term Loans. In March 2023, Dotdash Meredith entered into interest rate swaps on the Dotdash Meredith Term Loan B for a total notional amount of $350 million with a maturity date of April 1, 2027. The interest rate swaps synthetically convert $350 million of the Dotdash Meredith Term Loan B for the duration of the interest rate swaps from a variable rate to a fixed rate of approximately 7.92% ((i) the weighted average fixed interest rate of approximately 3.82% on the interest rate swaps plus (ii) the adjustment to the secured overnight financing rate of 0.10% plus (iii) the base rate of 4.00%), beginning on April 3, 2023. The interest rate swaps are expected to be highly effective. See " Note 4—Accumulated Other Comprehensive (Loss) Income " for the net unrealized gains recognized in "Accumulated other comprehensive loss" and realized gains reclassified into “Interest expense” for the three and nine months ended September 30, 2023. At September 30, 2023, approximately $5.1 million is expected to be reclassified into interest expense within the next twelve months as realized gains. The related asset of $8.1 million is included in “Other non-current assets” in the balance sheet at September 30, 2023. The Dotdash Meredith Term Loan A requires quarterly principal payments of approximately $4.4 million through December 31, 2024, $8.8 million through December 31, 2025 and approximately $13.1 million thereafter through maturity. The Dotdash Meredith Term Loan B requires quarterly payments of $3.1 million through maturity. The Dotdash Meredith Term Loan B may require additional annual principal payments as part of an excess cash flow sweep provision, the amount of which, in part, is governed by the applicable net leverage ratio. No such payment was required related to the period ended December 31, 2022. There were no outstanding borrowings under the Dotdash Meredith Revolving Facility at September 30, 2023 and December 31, 2022. The annual commitment fee on undrawn funds is based on Dotdash Meredith's consolidated net leverage ratio, as defined in the Dotdash Meredith Credit Agreement, most recently reported and was 40 basis points at both September 30, 2023 and December 31, 2022. Any borrowings under the Dotdash Meredith Revolving Facility would bear interest, at Dotdash Meredith's option, at either a base rate or Adjusted Term SOFR, plus an applicable margin, which is based on Dotdash Meredith's consolidated net leverage ratio. As of the last day of any calendar quarter, if either (i) $1.00 or more of loans under the Dotdash Meredith Revolving Facility or Dotdash Meredith Term Loan A are outstanding, or (ii) the outstanding face amount of undrawn letters of credit, other than cash collateralized letters of credit at 102% of face value, exceeds $25 million, subject to certain increases for qualifying material acquisitions, then Dotdash Meredith will not permit the consolidated net leverage ratio, which permits netting of up to $250 million in cash and cash equivalents, as of the last day of such quarter to exceed 5.5 to 1.0. The Dotdash Meredith Credit Agreement also contains covenants that would limit Dotdash Meredith’s ability to pay dividends, incur incremental secured indebtedness, or make distributions or certain investments in the event a default has occurred or if Dotdash Meredith’s consolidated net leverage ratio exceeds 4.0 to 1.0, subject to certain available amounts as defined in the Dotdash Meredith Credit Agreement. This ratio was exceeded for both test periods ended September 30, 2023 and December 31, 2022. The Dotdash Meredith Credit Agreement also permits the Company to, among other things, contribute cash to Dotdash Meredith, which will provide additional liquidity to ensure that Dotdash Meredith does not exceed certain consolidated net leverage ratios for any test period, as further defined in the Dotdash Meredith Credit Agreement. In connection with these capital contributions, Dotdash Meredith may make distributions to IAC in amounts not more than any such capital contributions, provided that no default has occurred and is continuing. Such capital contributions and subsequent distributions impact the consolidated net leverage ratios of Dotdash Meredith. In the three and nine months ended September 30, 2023, the Company contributed $125.0 million and $405.0 million, respectively, to Dotdash Meredith, which Dotdash Meredith subsequently distributed back to the Company $125.0 million in October 2023 and $130.0 million and $280.0 million in the three and nine months ended September 30, 2023, respectively. The obligations under the Dotdash Meredith Credit Agreement are guaranteed by certain of Dotdash Meredith's wholly-owned subsidiaries and are secured by substantially all of the assets of Dotdash Meredith and certain of its subsidiaries. ANGI Group Debt ANGI Group, LLC ("ANGI Group"), a direct wholly-owned subsidiary of Angi Inc., issued the ANGI Group Senior Notes on August 20, 2020. These notes may be redeemed at the redemption prices, plus accrued and unpaid interest thereon, if any, as set forth in the indenture governing the notes.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The overall concept that the Company employs in determining its operating segments is to present the financial information in a manner consistent with the chief operating decision maker's view of the businesses. In addition, we consider how the businesses are organized as to segment management and the focus of the businesses with regards to the types of services or products offered or the target market. Operating segments are combined for reporting purposes if they meet certain aggregation criteria, such as the Search segment, which principally relate to the similarity of their economic characteristics, or, in the case of Emerging & Other, do not meet the quantitative thresholds that require presentation as separate reportable segments. The following table presents revenue by reportable segment: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (In thousands) Revenue Dotdash Meredith Digital $ 212,050 $ 220,749 $ 608,819 $ 671,424 Print 211,259 251,471 625,046 801,756 Intersegment eliminations (a) (5,852) (5,135) (14,828) (16,100) Total Dotdash Meredith 417,457 467,085 1,219,037 1,457,080 Angi Inc.

Restructuring and Related Activities [Abstract]
DOTDASH MEREDITH RESTRUCTURING CHARGES, TRANSACTION-RELATED EXPENSES AND CHANGE-IN-CONTROL PAYMENTS	DOTDASH MEREDITH RESTRUCTURING CHARGES, TRANSACTION-RELATED EXPENSES AND CHANGE-IN-CONTROL PAYMENTS Restructuring Charges During 2023, Dotdash Meredith continued to incur costs related to a voluntary retirement program announced in the first quarter of 2022 and recorded adjustments to previously accrued amounts related to a reduction in force plan, for which the related expenses were accrued primarily in the fourth quarter of 2022. During 2022, Dotdash Meredith management committed to several actions to improve efficiencies and better align its cost structure following the acquisition of Meredith on December 1, 2021, which included: (i) the discontinuation of certain print publications and the shutdown of PeopleTV, for which the related expense was primarily reflected in the first quarter of 2022, (ii) the aforementioned voluntary retirement program, for which the related expense was primarily reflected in the first half of 2022, (iii) the consolidation of certain leased office space, for which the related expense was reflected in the third quarter of 2022 and (iv) the aforementioned reduction in force plan. These actions resulted in $80.2 million of restructuring charges incurred for the year ended December 31, 2022. A summary of the costs incurred, payments and related accruals is presented below. The Company anticipates the estimated remaining costs associated with the 2022 restructuring events will be paid by December 31, 2023 from existing cash on hand.

The actuarial gain of $1.2 million for the nine months ended September 30, 2023 primarily relates to investment performance, an increase in the discount rate and updates to participant census data. Settlements during the three and nine months ended September 30, 2022 triggered remeasurements of the funded pension plan in the U.S. The actuarial gain of $2.6 million for the three months ended September 30, 2022 primarily relates to assumption changes due to increases in the discount rate and updates to participant census data. The actuarial loss of $7.5 million for the nine months ended September 30, 2022 primarily relates to the decline in the fair value of the pension plan's assets exceeding the decline in the plan liabilities, partially offset by a gain related to the revaluation of an annuity contract and the gain in the third quarter of 2022 described above. Settlements during the nine months ended September 30, 2022 triggered remeasurements of the funded pension plan in the United Kingdom ("U.K."). The actuarial loss of $68.6 million for the nine months ended September 30, 2022 primarily relates to the decline in the fair value of the pension plan's assets exceeding the decline in the plan liabilities due to higher interest rates. The following table summarizes the weighted average expected return on plan assets used to determine the net periodic benefit costs at September 30, 2023 following the remeasurements, and December 31, 2022, respectively: September 30, 2023 December 31, 2022 Pension Domestic Domestic Expected return on plan assets 4.48 % 2.80 %

INCOME TAXES

INCOME TAXES	9 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES At the end of each interim period, the Company estimates the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to significant, unusual, or extraordinary items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which they occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or unrecognized tax benefits is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences and the likelihood of the realization of deferred tax assets generated in the current year. The accounting estimates used to compute the provision or benefit for income taxes may change as new events occur, more experience is acquired, additional information is obtained or the Company's tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision or benefit in the quarter in which the change occurs. Included in the income tax benefit for the three months ended September 30, 2023 was a benefit of $2.8 million due to a higher estimated annual effective tax rate from that applied to the second quarter's year-to-date ordinary loss from continuing operations. The higher estimated annual effective rate was due primarily to the reduced impact that forecasted nondeductible compensation expense had on the increase in forecasted ordinary pre-tax losses and state taxes. For the three and nine months ended September 30, 2023, the Company recorded an income tax benefit of $118.8 million and $3.6 million, respectively, which represents an effective income tax rate of 23% and 5%, respectively. For the three months ended September 30, 2023, the effective income tax rate was higher than the statutory rate of 21% due primarily to state taxes. For the nine months ended September 30, 2023, the effective income tax rate was lower than the statutory rate of 21% due primarily to nondeductible compensation expense, return to provision adjustments, foreign income taxed at different statutory rates and unconsolidated tax losses, partially offset by research credits and the realization of capital losses. For the three and nine months ended September 30, 2022, the Company recorded an income tax benefit of $26.1 million and $325.5 million, respectively, which represents an effective income tax rate of 28% and 22%, respectively. For the three months ended September 30, 2022, the effective income tax rate was higher than the statutory rate of 21% due primarily to the realization of a capital loss. For the nine months ended September 30, 2022, the effective income tax rate was higher than the statutory rate of 21% due primarily to state taxes, offset by the non-deductible portion of the Mosaic Group goodwill impairment charge. The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. Accruals for interest and penalties are not material. The Company's income taxes are routinely under audit by federal, state, local and foreign authorities as a result of previously filed separate company and consolidated tax returns for periods prior to the June 30, 2020 separation of IAC from Match Group (the "Match Separation") and for its tax returns filed on a standalone basis following the Match Separation. These audits include questioning the timing and the amount of income and deductions and the allocation of income and deductions among various tax jurisdictions. On June 27, 2023, the Joint Committee of Taxation completed its review of the federal income tax returns for the years ended December 31, 2013 through 2019, which include the operations of the Company, and approved the audit settlement previously agreed to with the Internal Revenue Services ("IRS"). The statute of limitations for the years 2013 through 2019 expires on December 31, 2023. The resolution of this IRS examination will result in a net liability to Match Group of $2.5 million excluding interest, which was previously accrued. Returns filed in various other jurisdictions are open to examination for tax years beginning with 2013. Income taxes payable include unrecognized tax benefits considered sufficient to pay assessments that may result from the examination of prior year tax returns. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may not accurately anticipate actual outcomes and, therefore, may require periodic adjustment. Although management currently believes changes in unrecognized tax benefits from period to period and differences between amounts paid, if any, upon resolution of issues raised in audits and amounts previously provided will not have a material impact on the liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. At September 30, 2023 and December 31, 2022, unrecognized tax benefits, including interest and penalties, were $18.9 million and $16.6 million, respectively. Unrecognized tax benefits, including interest and penalties, at September 30, 2023 increased by $2.3 million due primarily to research credits, partially offset by settlements. If unrecognized tax benefits at September 30, 2023 are subsequently recognized, $17.9 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount at December 31, 2022 was $15.4 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $0.8 million by September 30, 2024 due to expected settlements of which $0.7 million would reduce the income tax provision. The Company regularly assesses the realizability of deferred tax assets considering all available evidence including, to the extent applicable, the nature, frequency and severity of prior cumulative losses, forecasts of future taxable income, tax filing status, the duration of statutory carryforward periods, available tax planning and historical experience. At September 30, 2023, the Company has a U.S. gross deferred tax asset of $840.4 million that the Company expects to fully utilize on a more likely than not basis. Of this amount, $525.5 million will be utilized upon the future reversal of deferred tax liabilities and the remaining net deferred tax asset of $314.9 million will be utilized based on forecasts of future taxable income. The Company's most significant net deferred tax asset that could expire relates to U.S. federal net operating loss ("NOL") carryforwards of $40.4 million. The Company expects to generate sufficient future taxable income of at least $192.6 million prior to the expiration of these NOLs, the majority of which expire between 2033 and 2036, to fully realize this deferred tax asset.

LOSS PER SHARE

LOSS PER SHARE	9 Months Ended
	Sep. 30, 2023
Earnings Per Share [Abstract]
LOSS PER SHARE	LOSS PER SHARE The Company treats its common stock and Class B common stock as one class of stock for net earnings (loss) per share ("EPS") purposes as both classes of stock participate in earnings, dividends and other distributions on the same basis. The restricted stock award granted to our Chief Executive Officer ("CEO") on November 5, 2020 is a participating security and the Company calculates basic EPS using the two-class method since those restricted shares are unvested and have a non-forfeitable dividend right in the event the Company declares a cash dividend on common shares and participate in all other distributions of the Company in the same manner as all other IAC common shares. Diluted EPS is calculated, on the most dilutive basis, which excludes awards that would be anti-dilutive, including the restricted stock award granted to our CEO. Undistributed earnings allocated to the participating security is subtracted from earnings in determining earnings attributable to holders of IAC common stock and Class B common stock for basic EPS. Basic EPS is computed by dividing net earnings (loss) attributable to holders of IAC common stock and Class B common stock by the weighted-average number of shares of common stock and Class B common stock outstanding during the period. For the calculation of diluted EPS, net earnings (loss) attributable to holders of IAC common stock and Class B common stock is adjusted for the impact from our public subsidiary's dilutive securities, if applicable, and the reallocation of undistributed earnings allocated to the participating security by the weighted-average number of common stock and Class B common stock outstanding plus dilutive securities during the period. The numerator and denominator of basic and diluted EPS computations for the Company’s common stock and Class B common stock are calculated as follows: Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (In thousands, except per share data) Basic EPS: Numerator: Net loss $ (392,022) $ (65,847) $ (68,333) $ (1,182,139) Net loss attributable to noncontrolling interests 1,484 2,024 6,525 13,388 Net earnings attributed to unvested participating security — — — — Net loss attributable to IAC common stock and Class B common stock shareholders $ (390,538) $ (63,823) $ (61,808) $ (1,168,751) Denominator: Weighted average basic IAC common stock and Class B common stock shares outstanding (a) 82,826 86,022 83,804 86,515 Loss per share attributable to IAC common stock and Class B common stock shareholders: Loss per share $ (4.72) $ (0.74) $ (0.74) $ (13.51) Three Months Ended September 30, Nine Months Ended September 30, 2023 2022 2023 2022 (In thousands, except per share data) Diluted EPS: Numerator: Net loss $ (392,022) $ (65,847) $ (68,333) $ (1,182,139) Net loss attributable to noncontrolling interests 1,484 2,024 6,525 13,388 Net earnings attributed to unvested participating security — — — — Impact from public subsidiaries' dilutive securities (b) — — — — Net loss attributable to IAC common stock and Class B common stock shareholders $ (390,538) $ (63,823) $ (61,808) $ (1,168,751) Denominator: Weighted average basic IAC common stock and Class B common stock shares outstanding (a) 82,826 86,022 83,804 86,515 Dilutive securities (b)(c) — — — — Denominator for earnings per share—weighted average shares (b)(c) 82,826 86,022 83,804 86,515 Loss per share attributable to IAC common stock and Class B common stock shareholders: Loss per share $ (4.72) $ (0.74) $ (0.74) $ (13.51) _____________________ (a) On November 5, 2020, IAC's CEO was granted a stock-based award in the form of 3.0 million shares of restricted common stock. The number of shares that ultimately vests is subject to the satisfaction of growth targets in IAC's stock price over the 10-year service condition of the award. These restricted shares have a non-forfeitable dividend right in the event the Company declares a cash dividend on its common shares and participate in all other distributions of the Company in the same manner as all other IAC common shares. Accordingly, the two-class method of calculating EPS is used. While the restricted shares are presented as outstanding shares in the balance sheet, these shares are excluded from the weighted average shares outstanding in calculating basic EPS and the allocable portion of net earnings are also excluded. Fully diluted EPS reflects the impact on earnings and fully diluted shares in the manner that is most dilutive. (b) IAC has the option to settle certain Angi Inc. stock-based awards in its shares. The impact on net earnings relates to the settlement of Angi Inc.'s dilutive securities in IAC common shares. For the three and nine months ended September 30, 2023 and 2022, these Angi Inc. equity awards were anti-dilutive. (c) For the three and nine months ended September 30, 2023 and 2022, the Company had a loss from operations and, as a result, approximately 8.0 million and 8.0 million potentially dilutive securities, respectively, were excluded from computing diluted EPS because the impact would have been anti-dilutive. Accordingly, the weighted average basic shares outstanding were used to compute the EPS amounts for the three and nine months ended September 30, 2023 and 2022.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES In the ordinary course of business, the Company is a party to various lawsuits. The Company establishes accruals for specific legal matters when it determines that the likelihood of an unfavorable outcome is probable and the loss is reasonably estimable. Management has also identified certain other legal matters where it believes an unfavorable outcome is not probable and, therefore, no accrual is established. Although management currently believes that resolving claims against the Company, including claims where an unfavorable outcome is reasonably possible, will not have a material impact on the liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management's view of these matters may change in the future. The Company also evaluates other contingent matters, including uncertain income tax positions and non-income tax contingencies, to assess the likelihood of an unfavorable outcome and estimated extent of potential loss. It is possible that an unfavorable outcome of one or more of these lawsuits or other contingencies could have a material impact on the liquidity, results of operations, or financial condition of the Company. See " Note 8—Income Taxes " for information related to uncertain income tax positions.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	RELATED PARTY TRANSACTIONS IAC and Angi Inc. Allocation of CEO Compensation and Certain Expenses Joseph Levin, CEO of IAC and Chairman of Angi Inc., was appointed CEO of Angi Inc. on October 10, 2022. As a result, for the three and nine months ended September 30, 2023, IAC allocated $2.6 million and $7.2 million, respectively, in costs to Angi Inc. (including salary, benefits, stock-based compensation and costs related to the CEO's office). These costs were allocated from IAC based upon time spent on Angi Inc. by Mr. Levin. Management considers the allocation method to be reasonable. The allocated costs also include costs directly attributable to Angi Inc. that were initially paid for by IAC and billed by IAC to Angi Inc. The Combination and Related Agreements The Company and Angi Inc., in connection with the transaction resulting in the formation of Angi Inc. in 2017, which is referred to as the "Combination," entered into a contribution agreement; an investor rights agreement; a services agreement; a tax sharing agreement; and an employee matters agreement, which collectively govern the relationship between IAC and Angi Inc. IAC and Vimeo Inc. ("Vimeo") In connection with the spin-off of Vimeo from IAC, the parties entered in several agreements to govern their relationship following the completion of the transaction, certain of which remain in effect and are as follows: a separation agreement, a tax matters agreement and an employee matters agreement. Following the completion of the transaction, Vimeo and IAC entered into certain commercial agreements, including lease agreements, which IAC believes are ordinary course and have been negotiated at arm's length. The Company and Vimeo are related parties because Mr. Diller is the beneficial owner of more than 10% of the voting interests in both IAC and Vimeo. The Company has an outstanding receivable of $0.8 million due from Vimeo pursuant to the separation agreement at September 30, 2023 and December 31, 2022. This amount is included in "Other current assets" in the balance sheet and was paid in full in October 2023. The Company charged Vimeo rent pursuant to lease agreements of $0.9 million and $2.6 million for the three and nine months ended September 30, 2023, respectively, and $0.7 million and $3.7 million for the three and nine months ended September 30, 2022, respectively. At September 30, 2023, the Company has an outstanding receivable of $0.2 million due from Vimeo pursuant to the lease agreements. This amount is included in "Other non-current assets" in the balance sheet. At December 31, 2022, there were no outstanding receivables due from Vimeo pursuant to the lease agreements. IAC and Expedia At September 30, 2023, the Company and Expedia each had a 50% ownership interest in two aircraft that may be used by both companies. Members of the aircraft flight crews are employed by an entity in which the Company and Expedia each have a 50% ownership interest. The Company and Expedia have agreed to share costs relating to flight crew compensation and benefits pro-rata according to each company’s respective usage of the aircraft, for which they are separately billed by the entity described above. The Company and Expedia are related parties because Mr. Diller serves as Chairman and Senior Executive of both IAC and Expedia. For the three and nine months ended September 30, 2023 and 2022, total payments made to this entity by the Company were not material. In addition, Expedia may use certain aircraft owned 100% by a subsidiary of the Company on a cost basis. For the three and nine months ended September 30, 2023 and 2022, the payments made by Expedia to the Company pursuant to this arrangement were not material.

THE COMPANY AND SUMMARY OF SI_2

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Sep. 30, 2023
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	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	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	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	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 a variable rate to a 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 3—Long-term Debt " for additional information.
General Revenue Recognition	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 nine months ended September 30, 2022, if Services revenue were recorded on a net basis, revenue would have been reduced by $64.8 million and $187.5 million, respectively. The Company's disaggregated revenue disclosures are presented in " Note 5—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 $165.8 million and $0.1 million, respectively, at September 30, 2023 and $157.1 million and $0.2 million, respectively, at December 31, 2022. During the nine months ended September 30, 2023, the Company recognized $147.8 million of revenue that was included in the deferred revenue balance at December 31, 2022. During the nine months ended September 30, 2022, the Company recognized $145.4 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")	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.
Recent Accounting Pronouncements	Recent Accounting PronouncementsThere 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	Reclassifications Certain prior year amounts have been reclassified to conform to the current year presentation.

The number of shares that ultimately vests is subject to the satisfaction of growth targets in IAC's stock price over the 10-year service condition of the award. These restricted shares have a non-forfeitable dividend right in the event the Company declares a cash dividend on its common shares and participate in all other distributions of the Company in the same manner as all other IAC common shares. Accordingly, the two-class method of calculating EPS is used. While the restricted shares are presented as outstanding shares in the balance sheet, these shares are excluded from the weighted average shares outstanding in calculating basic EPS and the allocable portion of net earnings are also excluded. Fully diluted EPS reflects the impact on earnings and fully diluted shares in the manner that is most dilutive. (b) IAC has the option to settle certain Angi Inc. stock-based awards in its shares. The impact on net earnings relates to the settlement of Angi Inc.'s dilutive securities in IAC common shares. For the three and nine months ended September 30, 2023 and 2022, these Angi Inc. equity awards were anti-dilutive. (c) For the three and nine months ended September 30, 2023 and 2022, the Company had a loss from operations and, as a result, approximately 8.0 million and 8.0 million potentially dilutive securities, respectively, were excluded from computing diluted EPS because the impact would have been anti-dilutive. Accordingly, the weighted average basic shares outstanding were used to compute the EPS amounts for the three and nine months ended September 30, 2023 and 2022.
