THE COMPANY AND SUMMARY OF SIGN

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	3 Months Ended
	Mar. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Acquisition of Meredith On December 1, 2021, Dotdash Media Inc. (formerly known as About Inc., and referred to herein as "Dotdash"), a wholly-owned subsidiary of IAC/InterActiveCorp ("IAC"), completed the acquisition of Meredith Holdings Corporation (" Meredith "), which holds Meredith Corporation's national media business, consisting of its digital and magazine businesses, and its corporate operations. The parent of the combined entity is Dotdash Meredith, Inc. ("Dotdash Meredith"). See “ Note 4—Business Combinations ” for a description of the acquisition of Meredith. Vimeo Spin-off On May 25, 2021, IAC completed the spin-off of its full stake in Vimeo, Inc. (formerly Vimeo Holdings, Inc. ("Vimeo")) to IAC shareholders (which we refer to as the “Spin-off”). Following the Spin-off, Vimeo became an independent, separately traded public company. Therefore, Vimeo is presented as a discontinued operation within IAC's financial statements for all periods prior to May 25, 2021. See “ Note 3—Discontinued Operations ” for additional details. Nature of Operations IAC today is comprised of Dotdash Meredith, Angi Inc. and Care.com, as well as a number of other businesses ranging from early stage to established. As used herein, "IAC," the "Company," "we," "our" or "us" and similar terms refer to IAC/InterActiveCorp and its subsidiaries (unless the context requires otherwise). Basis of Presentation The Company prepares its consolidated financial statements (collectively referred to herein as "financial statements") in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP"). The consolidated 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 amongst the Company and its subsidiaries have been eliminated. The unaudited 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 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, 2021. COVID-19 Update The impact on the Company from the COVID-19 pandemic and the measures designed to contain its spread has been varied and volatile. As previously disclosed, the impact of COVID-19 on the businesses in IAC's Angi Inc. segment initially resulted in a decline in demand for service requests, driven primarily by decreases in demand in certain categories of jobs (particularly discretionary indoor projects). While these businesses experienced a rebound in service requests from mid-2020 through early 2021, service requests started to decline in May 2021 and continued to decline into the first quarter of 2022 because of Angi Inc.'s brand integration that began in March 2021 and, in late 2021 and early 2022, the Omicron variant surge. Moreover, many service professionals’ businesses have been and continue to be adversely impacted by labor and material constraints and many service professionals have limited capacity to take on new business, which continues to negatively impact the ability of Angi Inc.'s businesses to monetize service requests. Although Angi Inc.'s ability to monetize service requests rebounded modestly in the second half of 2021 and first quarter of 2022, it still has not returned to levels experienced pre-COVID-19. No assurances can be provided that Angi Inc. will continue to be able to improve monetization, or that service professionals’ businesses and, as a consequence, our revenue and profitability will not continue to be adversely impacted in the future. In addition, in the first quarter of 2022, revenue at Dotdash, excluding Meredith, declined compared to the first quarter of 2021 due to lower traffic to its sites compared to prior year COVID-19 traffic highs, impacting both display advertising and performance marketing revenue. The extent to which developments related to the COVID-19 pandemic and measures designed to curb its spread continue to impact the Company’s business, financial condition and results of operations will depend on future developments, all of which are highly uncertain and many of which are beyond the Company’s control, including the continuing spread of COVID-19, the severity of resurgences of COVID-19 caused by variant strains of the virus, the effectiveness of vaccines and attitudes toward receiving them, materials and supply chain constraints, labor shortages, the scope of governmental and other restrictions on travel, discretionary services and other activity, and public reactions to these developments. 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 equity securities; the carrying value of accounts receivable, including the determination of the allowance for credit losses and the determination of revenue reserves; the determination of the customer relationship period for certain costs to obtain a contract with a customer; the carrying value of right-of-use assets ("ROU assets"); the useful lives and recoverability of buildings, capitalized software, leasehold improvements and equipment and definite-lived intangible assets; the fair value of assets acquired and liabilities assumed as a result of an acquisition and the allocation of purchase price to the identifiable intangible assets acquired during the measurement period; the recoverability of goodwill and indefinite-lived intangible assets; the fair value of equity securities without readily determinable fair values; contingencies; the fair value of acquisition-related contingent consideration arrangements; unrecognized tax benefits; the valuation allowance for deferred income tax assets; pension and postretirement benefit expenses, including actuarial assumptions regarding discount rates, expected returns on plan assets 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. Accounting for Investments in Equity Securities Investments in equity securities, other than those of the Company's consolidated subsidiaries and those accounted for under the equity method, if applicable, are accounted for at fair value or under the measurement alternative of Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2016-01, Recognition and Measurement of Financial Assets and Liabilities , with any changes to fair value recognized in "Other income, net" in the statement of operations each reporting period. Under the measurement alternative, equity investments without readily determinable fair values are carried at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar securities of the same issuer; fair value is generally determined based on a market approach as of the transaction date. A security will be considered identical or similar if it has identical or similar rights to the equity securities held by the Company. The Company accounts for investments in the common stock or in-substance common stock of entities in which the Company has the ability to exercise significant influence over the operating and financial matters of the investee, but does not have a controlling financial interest, using the equity method. At March 31, 2022 and December 31, 2021, the Company has one investment accounted for using the equity method, which is included in "Long-term investments" in the balance sheet. See " Note 5—Financial Instruments and Fair Value Measurements " for additional information on investments in equity securities. General Revenue Recognition 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. The Company's disaggregated revenue disclosures are presented in " Note 9—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 of the applicable subscription period or expected completion of its performance obligation is one year or less. The current and non-current deferred revenue balances are $165.5 million and $0.4 million, respectively, at December 31, 2021, and $137.7 million and $0.7 million, respectively, at December 31, 2020. During the three months ended March 31, 2022, the Company recognized $90.0 million of revenue that was included in the deferred revenue balance at December 31, 2021. During the three months ended March 31, 2021, the Company recognized $66.1 million of revenue that was included in the deferred revenue balance at December 31, 2020. The current and non-current deferred revenue balances are $178.1 million and $0.5 million, at March 31, 2022, respectively. Non-current deferred revenue is included in "Other long-term liabilities" in the balance sheet. Practical Expedients and Exemptions As permitted under the practical expedient available under ASU No. 2014-09, Revenue from Contracts with Customers, 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. Costs to Obtain a Contract with a Customer The Company uses a portfolio approach to assess the accounting treatment of the incremental costs to obtain a contract with a customer. The Company recognizes an asset for these costs if we expect to recover those costs. To the extent that these costs are capitalized, the resultant asset is amortized on a systematic basis consistent with the pattern of the transfer of the services to which the asset relates. The Company has determined that certain costs, primarily commissions paid to employees pursuant to certain sales incentive programs and mobile app store fees, meet the requirements to be capitalized as a cost of obtaining a contract. Commissions Paid to Third-Party Agent Sales of Magazine Subscriptions Dotdash Meredith uses third-party agents to obtain certain subscribers. The agents are paid a commission, which can be as much as the subscription price charged to the subscriber. Dotdash Meredith subscriptions do not have substantive termination penalties; therefore, the contract term is determined on an issue-by-issue basis. Accordingly, these costs do not qualify for capitalization because there is no contract with a customer until a copy is served to a customer; therefore these costs are expensed when the publication is sent to the customer. Dotdash Meredith recognizes a liability to the extent the commission is refundable to the third-party agent. Dotdash Meredith expenses additional amounts paid to agents (such as per subscriber bounties) to acquire subscribers as incurred. Commissions Paid to Employees Pursuant to Sales Incentive Programs The Company has determined that commissions paid to employees pursuant to certain sales incentive programs meet the requirements to be capitalized as the incremental costs to obtain a contract with a customer. When customer renewals are expected and the renewal commission is not commensurate with the initial commission, the average customer life includes renewal periods. Capitalized commissions paid to employees pursuant to these sales incentive programs are amortized over the estimated customer relationship period. The Company calculates the anticipated customer relationship period as the average customer life, which is based on historical data. For sales incentive programs where the anticipated customer relationship period is one year or less, the Company has elected the practical expedient to expense the commissions as incurred. App Store Fees The Company pays fees to the Apple App Store and the Google Play Store for the distribution of our paid mobile apps. The Company capitalizes and amortizes mobile app store fees related to subscriptions over the term of the applicable subscription. The following table presents the capitalized costs to obtain a contract with a customer at March 31, 2022 and December 31, 2021, respectively: March 31, 2022 December 31, 2021 Sales Commissions App Store Fees Total Sales Commissions App Store Fees Total (In thousands) Current $ 42,794 $ 8,640 $ 51,434 $ 39,669 $ 9,023 $ 48,692 Non-current 5,987 — 5,987 6,086 — 6,086 Total $ 48,781 $ 8,640 $ 57,421 $ 45,755 $ 9,023 $ 54,778 The current and non-current capitalized costs to obtain a contract with a customer are included in "Other current assets" and "Other non-current assets," respectively, in the balance sheet. Certain Risks and Concentrations—Services Agreement with Google (the "Services Agreement") A meaningful portion of the Company's revenue (and a substantial portion of IAC's net cash from operating activities attributable to continuing operations that it can freely access) is attributable to the Services Agreement. In addition, the Company earns certain other advertising revenue from Google that is not attributable to the Services Agreement. For the three months ended March 31, 2022 and 2021, total revenue earned from Google was $193.4 million and $171.8 million , respectively, representing 15% and 22%, respectively, of the Company's revenue. The related accounts receivable totaled $66.8 million and $89.1 million at March 31, 2022 and December 31, 2021, respectively. The total revenue earned from the Services Agreement for the three months ended March 31, 2022 and 2021 was $147.1 million and $152.5 million, respectively, representing 11% and 19%, respectively, of the Company's total revenue. The revenue attributable to the Services Agreement is earned by Ask Media Group and the Desktop business, both within the Search segment. For the three months ended March 31, 2022 and 2021, revenue earned from the Services Agreement was $120.5 million and $121.4 million, respectively, within Ask Media Group and $26.6 million and $31.0 million, respectively, within the Desktop business . The Company and Google are parties to an amended Services Agreement, which expires on March 31, 2024 and provides for an automatic renewal for an additional one year period absent a notice of non-renewal from either party on or before March 31, 2023. 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. Certain industry-wide policy changes became effective on August 27, 2020. These industry-wide changes, combined with increased enforcement of policies under the Services Agreement, have had a negative impact on the results of operations of the B2C business. During the fourth quarter of 2020, Google suspended services with respect to some B2C's products and may do so with respect to other products in the future. As a result, the B2C business elected to modify certain marketing strategies in early January 2021. Subsequently, Google informed us of another policy change in the first quarter of 2021 that became effective on May 10, 2021. We anticipated that this Google policy change would eliminate our ability to successfully introduce and market new B2C products that would be profitable. Therefore, we undertook cost reduction measures and effectively eliminated all marketing of B2C products beginning in March 2021. This elimination of marketing has positively impacted profitability starting in the second quarter of 2021 because revenue from B2C products is earned over multiple periods beyond just the period in which the initial marketing is incurred. Following the cessation of the introduction of new products in March 2021, the B2C revenue stream relates solely to the then existing installed base of products. In 2022 and beyond, we expect the revenue and profits of the B2C business to decline significantly. Recent Accounting Pronouncements Accounting Pronouncements Not Yet Adopted by IAC There are no recently issued accounting pronouncements that have not yet been adopted 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.

INCOME TAXES

INCOME TAXES	3 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. For the three months ended March 31, 2022, the Company recorded an income tax benefit of $70.5 million, which represents an effective income tax rate of 23%, which is higher than the statutory rate of 21% due primarily to state taxes and excess tax benefits generated by the exercise and vesting of stock-based awards, partially offset by nondeductible stock-based compensation expense. For the three months ended March 31, 2021, the Company recorded an income tax provision of $53.3 million, which represents an effective income tax rate of 14% which is lower than the statutory rate of 21% due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards, partially offset by state taxes. 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. On December 19, 2019, IAC/InterActiveCorp ("Old IAC") entered into a Transaction Agreement (as amended, the "Transaction Agreement") with Match Group, Inc. ("Old MTCH"), IAC Holdings, Inc. ("New IAC" or the "Company"), a direct wholly-owned subsidiary of Old IAC, and Valentine Merger Sub LLC, an indirect wholly-owned subsidiary of Old IAC. On June 30, 2020, the businesses of Old MTCH were separated from the remaining businesses of Old IAC through a series of transactions that resulted in the pre-transaction stockholders of Old IAC owning shares in two, separate public companies—(1) Old IAC, which was renamed Match Group, Inc. ("New Match") and which owns the businesses of Old MTCH and certain Old IAC financing subsidiaries, and (2) New IAC, which was renamed IAC/InterActiveCorp, and which owns Old IAC's other businesses—and the pre-transaction stockholders of Old MTCH (other than Old IAC) owning shares in New Match. This transaction is referred to as the "MTCH Separation." The Company is routinely under audit by federal, state, local and foreign authorities in the area of income tax as a result of previously filed separate company and consolidated tax returns with Old IAC and for its tax returns filed on a standalone basis following the MTCH 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. The Internal Revenue Service ("IRS") has substantially completed its audit of Old IAC’s federal income tax returns for the years ended December 31, 2013 through 2017, and is currently auditing the years ended December 31, 2018 through 2019, which include the operations of the Company. The statute of limitations for the years 2013 through 2019 has been extended to December 31, 2023. Returns filed in various other jurisdictions are open to examination for tax years beginning with 2012. 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.

Business Combination and Asset Acquisition [Abstract]
BUSINESS COMBINATION	BUSINESS COMBINATION On December 1, 2021, Dotdash acquired Meredith under the terms of an agreement (the "Merger Agreement") dated as of October 6, 2021. At the effective time of the merger, each outstanding share of common stock of Meredith (other than certain excluded shares) was converted into the right to receive $42.18 in cash. Pursuant to the Merger Agreement, Meredith equity awards were cancelled, and in exchange each holder received such holder’s portion of the merger consideration as set forth in the Merger Agreement, less the per share exercise price in the case of stock options. The Company accounted for this acquisition as a business combination under the acquisition method of accounting. The total preliminary purchase price was calculated and allocated as follows: (In thousands) Common stock of Meredith $ 1,931,376 Cash payment used to settle a portion of Meredith debt 625,000 Cash settlement of all outstanding vested equity awards and deferred compensation 130,089 Total preliminary purchase price $ 2,686,465 The table below summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the date of acquisition: (In thousands) Cash and cash equivalents $ 12,436 Accounts receivable 373,091 Other current assets 90,371 Property and equipment 283,319 Goodwill 1,564,929 Intangible assets 1,095,500 Other non-current assets 682,214 Total assets 4,101,860 Customer deposit liability (140,690) Other current liabilities (457,549) Deferred income taxes (230,880) Other non-current liabilities (586,276) Net assets acquired $ 2,686,465 The Company acquired Meredith because it is complementary to Dotdash. The purchase was based on the expected future financial performance of Meredith under Dotdash leadership, not on the value of the net identifiable assets at the time of acquisition. This resulted in a significant portion of the preliminary purchase price being attributed to goodwill. The purchase price attributed to goodwill is not tax deductible. The preliminary fair values of the identifiable intangible assets acquired at the date of acquisition are as follows: (In thousands) Useful Life Indefinite-lived trade names and trademarks $ 432,800 Indefinite-lived Advertiser relationships 334,000 5-7 Licensee relationships 150,000 3-6 Trade name and trademarks 105,000 2-5 Subscriber relationships 73,700 1-2 Total identifiable intangible assets acquired $ 1,095,500 The allocation of the preliminary purchase price to certain assets acquired and liabilities assumed is provisional and is subject to review and revision during the measurement period, which the Company expects to extend through the fourth quarter of 2022. In addition, the Company is still in the process of identifying acquired assets and assumed liabilities, which may also result in an adjustment of the provisional amounts recorded. The subsequent adjustment of the provisional amounts may be material. The provisional amounts for assets acquired and liabilities assumed include the fair value of: 1. accounts receivable and other receivables, which has been adjusted for an estimated $10.1 million of gross contractual amounts not expected to be collected, may be subject to adjustment for reassessment of collectability as of the date of acquisition, collections and other adjustment subsequent to the acquisition; 2. prepaid expenses and other current and noncurrent assets, which will be subject to adjustment based upon a review of recoverability and consideration of other factors; 3. inventory; 4. property, plant and equipment, for which the preliminary estimates are subject to revision for: a. identification of assets acquired; b. finalization of preliminary appraisals; and c. determination of useful lives; 5. right of use assets and lease liabilities, which will be subject to adjustment upon completion of the review of the inputs, including sublease assumptions, for the calculations; 6. accounts payable and accrued expenses, which will be subject to adjustment based upon subsequent payment and assessment of other factors; 7. indemnification liabilities, which include pre-acquisition income tax and non-income tax liabilities, will be subject to adjustment for: a. the reconciliation of the income tax return to the income tax provision for Meredith Corporation's fiscal year ended June 30, 2021 and the short period return from July 1, 2021 through the date of acquisition; b. the assessment of the amounts of liabilities that existed at the date of acquisition based upon ongoing audits; c. the assessment of applicable tax rates and other factors; and d. the identification of other liabilities; 8. contingencies, the initial estimated recorded liability for which is approximately $100 million, including indemnification liabilities, will be subject to adjustment for additional items that are identified and for additional information obtained that will assist in the determination of liabilities as of the date of acquisition; 9. definite and indefinite-lived intangible assets acquired will be subject to adjustment as additional assets are identified, estimates and forecasts are refined and disaggregated, useful lives are finalized, and other factors deemed relevant are considered; 10. deferred income taxes will be subject to adjustment based upon the completion of the review of the book and tax bases of assets acquired and liabilities assumed, applicable tax rates and the impact of the revisions of estimates for the items described above; 11. goodwill will be subject to adjustment for the impact of the revisions of estimates for the items described above; and 12. the allocation of goodwill to reporting units, which is still in process of being assessed, will be subject to revision based upon the items described above and the finalization of the determination of fair value of the reporting units, which has not yet been completed. Unaudited pro forma financial information The unaudited pro forma financial information in the table below presents the results of the Company and Meredith as if the Meredith acquisition had occurred on January 1, 2020. The unaudited pro forma financial information includes adjustments required under the acquisition method of accounting and is presented for informational purposes only and is not necessarily indicative of the results that would have been achieved had this acquisition occurred on January 1, 2020. For the three months ended March 31, 2021, pro forma adjustments include an increase in amortization expense of $23.9 million related to intangible asset adjustments in purchase accounting. Three Months Ended March 31, 2021 (In thousands, except per share data) Revenue $ 1,254,571 Net earnings from continuing operations $ 371,736 Basic earnings per share from continuing operations $ 4.19 Diluted earnings per share from continuing operations $ 3.92 Net earnings attributable to IAC shareholders $ 381,919 Basic earnings per share attributable to IAC shareholders $ 4.29 Diluted earnings per share attributable to IAC shareholders $ 4.02

FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS	FINANCIAL INSTRUMENTS AND FAIR VALUE MEASUREMENTS Marketable Securities At March 31, 2022 and December 31, 2021, the fair value of marketable securities are as follows: March 31, 2022 December 31, 2021 (In thousands) Marketable equity securities $ 59,012 $ 19,788 Total marketable securities $ 59,012 $ 19,788 The Company has two investments in marketable equity securities at March 31, 2022, which are carried at fair value following the investees' initial public offerings, which took place in the third quarter of 2021 and the first quarter of 2022, respectively. Prior to the respective initial public offerings, these investments were accounted for as equity securities without readily determinable fair values. The Company recorded a net unrealized pre-tax gain of $34.4 million during the three months ended March 31, 2022 for these investments. The net unrealized pre-tax gain related to these investments is included in "Other income, net" in the statement of operations. Investment in MGM Resorts International March 31, 2022 December 31, 2021 (In thousands) Investment in MGM Resorts International ("MGM") $ 2,664,612 $ 2,649,442 On February 16, 2022, the Company purchased an additional 4.5 million shares of MGM for $202.5 million. Following this purchase, the Company owns approximately 63.5 million shares, representing a 14.5% ownership interest in MGM as of February 23, 2022. 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 the last trading day in the reporting period and any unrealized gains or losses are included in the statement of operations. For the three months ended March 31, 2022 and 2021, the Company recorded an unrealized pre-tax loss and an unrealized pre-tax gain on its investment in MGM of $187.3 million and $382.5 million, respectively. The cumulative unrealized net pre-tax gain through March 31, 2022 is $1.4 billion. Long-term Investments Long-term investments consist of: March 31, 2022 December 31, 2021 (In thousands) Equity securities without readily determinable fair values $ 319,727 $ 324,649 Equity method investment 3,198 3,189 Total long-term investments $ 322,925 $ 327,838 Equity Securities without Readily Determinable Fair Values The following table presents a summary of unrealized pre-tax gains recorded in "Other income, net" in the statement of operations as adjustments to the carrying value of equity securities without readily determinable fair values held at March 31, 2021. There were no unrealized pre-tax gains or losses recorded for the three months ended March 31, 2022. Three Months Ended (In thousands) Upward adjustments (gross unrealized pre-tax gains) $ 1,376 Total $ 1,376 The cumulative upward and downward adjustments (including impairments) to the carrying value of equity securities without readily determinable fair values held at March 31, 2022 were $28.7 million and $38.6 million, respectively. Realized and unrealized pre-tax gains and losses for the Company's investments without readily determinable fair values for the three months ended March 31, 2022 and 2021 are as follows: Three Months Ended March 31, 2022 2021 (In thousands) Realized pre-tax gains, net, for equity securities sold $ 468 $ 81 Unrealized pre-tax gains, net, on equity securities held — 1,376 Total pre-tax gains, net recognized $ 468 $ 1,457 All pre-tax gains and losses on equity securities without readily determinable fair values, realized and unrealized, are recognized in "Other income, net" in the statement of operations. Equity Method Investment The Company owns common shares of Turo Inc. ("Turo"), a peer-to-peer car sharing marketplace. This investment is accounted for under the equity method of accounting given the Company's ownership interest at March 31, 2022 of approximately 26.9% on a fully diluted basis in the form of preferred shares, which are not common stock equivalents. The Company accounts for the equity losses for this investment on a one quarter lag. 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: March 31, 2022 Quoted Market Significant Significant Total (In thousands) Assets: Cash equivalents: Money market funds $ 1,214,018 $ — $ — $ 1,214,018 Treasury discount notes — 299,989 — 299,989 Marketable equity securities 59,012 — — 59,012 Investment in MGM 2,664,612 — — 2,664,612 Other non-current assets: — Warrant — — 117,279 117,279 Total $ 3,937,642 $ 299,989 $ 117,279 $ 4,354,910 Liabilities: Contingent consideration arrangement $ — $ — December 31, 2021 Quoted Market Significant Significant Total (In thousands) Assets: Cash equivalents: Money market funds $ 1,660,921 $ — $ — $ 1,660,921 Time deposits — 6,057 — 6,057 Marketable equity security 19,788 — — 19,788 Investment in MGM 2,649,442 — — 2,649,442 Other non-current assets: Warrant — — 109,294 109,294 Total $ 4,330,151 $ 6,057 $ 109,294 $ 4,445,502 Liabilities: Contingent consideration arrangement $ (612) $ (612) 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 March 31, 2022 2021 Warrant Contingent Warrant (In thousands) Balance at January 1 $ 109,294 $ (612) $ 5,276 Total net gains: Fair value adjustments included in earnings 7,985 612 12,775 Balance at March 31 $ 117,279 $ — $ 18,051 Warrant As part of the Company's investment in Turo preferred shares, the Company received a warrant that is recorded at fair value each reporting period with any change included in "Other income, 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 March 31, 2022, the Company has two outstanding contingent consideration arrangements related to business combinations. The maximum contingent payments related to these arrangements is $7.0 million, however, as of March 31, 2022 the Company does not expect to make any further payments on these arrangements. Assets measured at fair value on a nonrecurring basis The Company's non-financial assets, such as goodwill, intangible assets, ROU assets and buildings, capitalized software, leasehold improvements and equipment, are adjusted to fair value only when an impairment is recognized. The Company's financial assets, comprising equity securities without readily determinable fair values, are adjusted to fair value when observable price changes are identified or an impairment is recognized. Such fair value measurements are based predominantly on Level 3 inputs. The Mosaic Group reporting unit fair value approximates its carrying value at March 31, 2022. To the extent there is a decline in the fair value of the reporting unit, a goodwill impairment would be recorded to the extent the carrying value exceeds the fair value. A 10% decline in the fair value of the Mosaic Group reporting unit would result in a goodwill impairment of approximately $25.0 million. Financial instruments measured at fair value only for disclosure purposes The following table presents the carrying value and the fair value of financial instruments measured at fair value only for disclosure purposes: March 31, 2022 December 31, 2021 Carrying Fair Carrying Fair (In thousands) Current portion of long-term debt $ (30,000) $ (29,925) $ (30,000) $ (29,550) Long-term debt, net (a) $ (2,039,655) $ (1,980,958) $ (2,046,237) $ (2,061,450) _____________________ (a) At March 31, 2022 and December 31, 2021, the carrying value of long-term debt, net includes unamortized original issue discount and debt issuance costs of $22.8 million and $23.8 million, respectively . At March 31, 2022 and December 31, 2021, the fair value of long-term debt, including the current portion, is estimated using observable market prices or indices for similar liabilities, which are Level 2 inputs.

The proceeds of the Dotdash Meredith Term Loans were used to fund a portion of the purchase price for the acquisition of Meredith and pay related fees and expenses. The Dotdash Meredith Term Loan A bears interest at an adjusted term secured overnight financing rate ("Adjusted Term SOFR") as defined in the Dotdash Meredith Credit Agreement plus an applicable margin depending on Dotdash Meredith's most recently reported consolidated net leverage ratio, as defined in the Dotdash Meredith Credit Agreement. At March 31, 2022 and December 31, 2021, the Dotdash Meredith Term Loan A bore interest at Adjusted Term SOFR plus 2.00%, or 2.29% and 2.15%, respectively. The Dotdash Meredith Term Loan B bore interest at Adjusted Term SOFR, subject to a minimum of 0.50%, plus 4.00%, or 4.50% at both March 31, 2022 and December 31, 2021. Interest payments are due at least quarterly through the terms of the Dotdash Meredith Term Loans. The outstanding balances of the Dotdash Meredith Term Loan A and Dotdash Meredith Term Loan B were $345.6 million and $1.25 billion at March 31, 2022, respectively, and $350.0 million and $1.25 billion at December 31, 2021, respectively. 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. Commencing December 31, 2022, pursuant to the Dotdash Meredith Credit Agreement, 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 Dotdash Meredith's net leverage ratio. There were no outstanding borrowings under the Dotdash Meredith Revolving Facility at March 31, 2022 and December 31, 2021. The annual commitment fee on undrawn funds is based on the consolidated net leverage ratio, as defined in the Dotdash Meredith Credit Agreement, most recently reported and was 35 basis points at both March 31, 2022 and December 31, 2021. Any borrowings under the Dotdash Meredith Revolving Facility would bear interest, at Dotdash Meredith's option, at either a base rate or term benchmark rate, plus an applicable margin, which is based on Dotdash Meredith's net leverage ratio. As of the last day of any calendar quarter ending on or after March 31, 2022, 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 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 or make distributions in the event a default has occurred or if Dotdash Meredith’s consolidated net leverage ratio (as defined in the Dotdash Meredith Credit Agreement) exceeds 4.0 to 1.0. There were no such limitations at March 31, 2022. 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 The ANGI Group Senior Notes were issued on August 20, 2020. At any time prior to August 15, 2023, these notes may be redeemed at a redemption price equal to the sum of the principal amount thereof, plus accrued and unpaid interest and a make-whole premium. Thereafter, these notes may be redeemed at the redemption prices set forth in the indenture governing the notes, plus accrued and unpaid interest thereon, if any, to the applicable redemption date. The indenture governing the ANGI Group Senior Notes contains a covenant that would limit ANGI Group’s ability to incur liens for borrowed money in the event a default has occurred or ANGI Group’s secured leverage ratio (as defined in the indenture) exceeds 3.75 to 1.0. At March 31, 2022 there were no limitations pursuant thereto. The $250 million ANGI Group Revolving Facility, which otherwise would have expired on November 5, 2023, was terminated effective August 3, 2021. No amounts were ever drawn under the ANGI Group Revolving Facility prior to its termination.

(LOSS) EARNINGS PER SHARE

(LOSS) EARNINGS PER SHARE	3 Months Ended

Earnings Per Share [Abstract]
(LOSS) EARNINGS PER SHARE	(LOSS) EARNINGS PER SHARE The Company treats its common stock and Class B common stock as one class of stock for net (loss) earnings 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 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. 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 (loss) earnings 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 (loss) earnings 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 March 31, 2022 2021 (In thousands, except per share data) Basic EPS: Numerator: Net (loss) earnings from continuing operations $ (240,893) $ 318,945 Net loss attributable to noncontrolling interests of continuing operations 5,095 1,036 Net earnings attributed to unvested participating security — (10,798) Net (loss) earnings from continuing operations attributable to IAC Common Stock and Class B common stock shareholders $ (235,798) $ 309,183 Net earnings from discontinued operations, net of tax $ — $ 9,956 Net earnings attributable to noncontrolling interests of discontinued operations — (809) Net earnings attributed to unvested participating security — (309) Net earnings from discontinued operations attributable to IAC Common Stock and Class B common stock shareholders $ — $ 8,838 Net (loss) earnings attributable to IAC Common Stock and Class B common stock shareholders $ (235,798) $ 318,021 Denominator: Weighted average basic IAC Common Stock and Class B common stock shares outstanding (a) 86,784 85,899 (Loss) earnings per share: (Loss) earnings per share from continuing operations attributable to IAC Common Stock and Class B common stock shareholders $ (2.72) $ 3.60 Earnings per share from discontinued operations, net of tax, attributable to IAC Common Stock and Class B common stock shareholders $ — $ 0.10 (Loss) earnings per share attributable to IAC Common Stock and Class B common stock shareholders $ (2.72) $ 3.70 Three Months Ended March 31, 2022 2021 (In thousands, except per share data) Diluted EPS: Numerator: Net (loss) earnings from continuing operations $ (240,893) $ 318,945 Net loss attributable to noncontrolling interests of continuing operations 5,095 1,036 Net earnings attributed to unvested participating security — (10,089) Impact from public subsidiaries' dilutive securities (b) — (18) Net (loss) earnings from continuing operations attributable to IAC Common Stock and Class B common stock shareholders $ (235,798) $ 309,874 Net earnings from discontinued operations, net of tax $ — $ 9,956 Net earnings attributable to noncontrolling interests of discontinued operations — (809) Net earnings attributed to unvested participating security — (288) Net earnings from discontinued operations attributable to IAC Common Stock and Class B common stock shareholders $ — $ 8,859 Net (loss) earnings attributable to IAC Common Stock and Class B common stock shareholders $ (235,798) $ 318,733 Denominator: Weighted average basic IAC Common Stock and Class B common stock shares outstanding (a) 86,784 85,899 Dilutive securities (b)(c)(d) — 6,239 Denominator for earnings per share—weighted average shares (b)(c)(d) 86,784 92,138 (Loss) earnings per share: (Loss) earnings per share from continuing operations attributable to IAC Common Stock and Class B common stock shareholders $ (2.72) $ 3.36 Earnings per share from discontinued operations, net of tax, attributable to IAC Common Stock and Class B common stock shareholders $ — $ 0.10 (Loss) earnings per share attributable to IAC Common Stock and Class B common stock shareholders $ (2.72) $ 3.46 _____________________ (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. For the three months ended March 31, 2022, both the Company and Angi Inc. had a loss from operations and as a result these awards were excluded from computing dilutive earnings per share because the impact would have been anti-dilutive. For the three months ended March 31, 2021 it was more dilutive for IAC to settle these Angi Inc. equity awards. The impact on net earnings relates to the settlement of Angi Inc.'s dilutive securities in IAC common shares. (c) For the three months ended March 31, 2022, the Company had a loss from continuing operations and, as a result, approximately 7.8 million potentially dilutive securities 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 months ended March 31, 2022. (d)

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, which principally relate to the similarity of their economic characteristics, or, in the case of the Emerging & Other reportable segment, do not meet the quantitative thresholds that require presentation as separate reportable segments. The determination of operating segments for Dotdash Meredith following the acquisition of Meredith is provisional; therefore, it is possible that a different level of segment reporting may be required following the completion of this determination. The following table presents revenue by reportable segment: Three Months Ended March 31, 2022 2021 (In thousands) Revenue Dotdash Meredith Digital $ 216,165 $ 65,421 Print 289,978 — Intra-segment eliminations (a) (5,672) — Total Dotdash Meredith 500,471 65,421 Angi Inc. 436,159 387,029 Search 223,385 181,034 Emerging & Other 166,994 153,156 Inter-segment eliminations (1,664) (70) Total $ 1,325,345 $ 786,570 The following table presents the revenue of the Company's segments disaggregated by type of service: Three Months Ended March 31, 2022 2021 (In thousands) Dotdash Meredith Digital: Display advertising revenue $ 137,090 $ 37,171 Performance marketing revenue 50,105 27,593 Licensing and other revenue 28,970 657 Total digital revenue 216,165 65,421 Print: Subscription revenue 132,607 — Advertising revenue 72,687 — Project and other revenue 33,025 — Newsstand revenue 31,239 — Performance marketing revenue 20,420 — Total print revenue 289,978 — Intra-segment eliminations (a) (5,672) — Total Dotdash Meredith revenue $ 500,471 $ 65,421 (a) Includes $5.6 million of intra-segment eliminations related to digital performance marketing revenue.

CONTINGENCIES

CONTINGENCIES	3 Months Ended

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES In the ordinary course of business, the Company is a party to various lawsuits. The Company establishes reserves 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 the Company believes an unfavorable outcome is not probable and, therefore, no reserve 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 income 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 2—Income Taxes " for additional information related to income tax contingencies.

THE COMPANY AND SUMMARY OF SI_2

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2022
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations	Nature of Operations IAC today is comprised of Dotdash Meredith, Angi Inc. and Care.com, as well as a number of other businesses ranging from early stage to established. As used herein, "IAC," the "Company," "we," "our" or "us" and similar terms refer to IAC/InterActiveCorp and its subsidiaries (unless the context requires otherwise).
Basis of Presentation	Basis of Presentation The Company prepares its consolidated financial statements (collectively referred to herein as "financial statements") in accordance with United States ("U.S.") generally accepted accounting principles ("GAAP"). The consolidated 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 amongst the Company and its subsidiaries have been eliminated. The unaudited 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 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, 2021.
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 equity securities; the carrying value of accounts receivable, including the determination of the allowance for credit losses and the determination of revenue reserves; the determination of the customer relationship period for certain costs to obtain a contract with a customer; the carrying value of right-of-use assets ("ROU assets"); the useful lives and recoverability of buildings, capitalized software, leasehold improvements and equipment and definite-lived intangible assets; the fair value of assets acquired and liabilities assumed as a result of an acquisition and the allocation of purchase price to the identifiable intangible assets acquired during the measurement period; the recoverability of goodwill and indefinite-lived intangible assets; the fair value of equity securities without readily determinable fair values; contingencies; the fair value of acquisition-related contingent consideration arrangements; unrecognized tax benefits; the valuation allowance for deferred income tax assets; pension and postretirement benefit expenses, including actuarial assumptions regarding discount rates, expected returns on plan assets 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.
Accounting for Investments in Equity Securities	Accounting for Investments in Equity Securities Investments in equity securities, other than those of the Company's consolidated subsidiaries and those accounted for under the equity method, if applicable, are accounted for at fair value or under the measurement alternative of Financial Accounting Standards Board ("FASB") Accounting Standards Update ("ASU") No. 2016-01, Recognition and Measurement of Financial Assets and Liabilities
General Revenue Recognition	General Revenue Recognition 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. The Company's disaggregated revenue disclosures are presented in " Note 9—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 of the applicable subscription period or expected completion of its performance obligation is one year or less. The current and non-current deferred revenue balances are $165.5 million and $0.4 million, respectively, at December 31, 2021, and $137.7 million and $0.7 million, respectively, at December 31, 2020. During the three months ended March 31, 2022, the Company recognized $90.0 million of revenue that was included in the deferred revenue balance at December 31, 2021. During the three months ended March 31, 2021, the Company recognized $66.1 million of revenue that was included in the deferred revenue balance at December 31, 2020. The current and non-current deferred revenue balances are $178.1 million and $0.5 million, at March 31, 2022, respectively. Non-current deferred revenue is included in "Other long-term liabilities" in the balance sheet. Practical Expedients and Exemptions As permitted under the practical expedient available under ASU No. 2014-09, Revenue from Contracts with Customers, 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. Costs to Obtain a Contract with a Customer The Company uses a portfolio approach to assess the accounting treatment of the incremental costs to obtain a contract with a customer. The Company recognizes an asset for these costs if we expect to recover those costs. To the extent that these costs are capitalized, the resultant asset is amortized on a systematic basis consistent with the pattern of the transfer of the services to which the asset relates. The Company has determined that certain costs, primarily commissions paid to employees pursuant to certain sales incentive programs and mobile app store fees, meet the requirements to be capitalized as a cost of obtaining a contract. Commissions Paid to Third-Party Agent Sales of Magazine Subscriptions Dotdash Meredith uses third-party agents to obtain certain subscribers. The agents are paid a commission, which can be as much as the subscription price charged to the subscriber. Dotdash Meredith subscriptions do not have substantive termination penalties; therefore, the contract term is determined on an issue-by-issue basis. Accordingly, these costs do not qualify for capitalization because there is no contract with a customer until a copy is served to a customer; therefore these costs are expensed when the publication is sent to the customer. Dotdash Meredith recognizes a liability to the extent the commission is refundable to the third-party agent. Dotdash Meredith expenses additional amounts paid to agents (such as per subscriber bounties) to acquire subscribers as incurred. Commissions Paid to Employees Pursuant to Sales Incentive Programs The Company has determined that commissions paid to employees pursuant to certain sales incentive programs meet the requirements to be capitalized as the incremental costs to obtain a contract with a customer. When customer renewals are expected and the renewal commission is not commensurate with the initial commission, the average customer life includes renewal periods. Capitalized commissions paid to employees pursuant to these sales incentive programs are amortized over the estimated customer relationship period. The Company calculates the anticipated customer relationship period as the average customer life, which is based on historical data. For sales incentive programs where the anticipated customer relationship period is one year or less, the Company has elected the practical expedient to expense the commissions as incurred. App Store Fees The Company pays fees to the Apple App Store and the Google Play Store for the distribution of our paid mobile apps. The Company capitalizes and amortizes mobile app store fees related to subscriptions over the term of the applicable subscription. The following table presents the capitalized costs to obtain a contract with a customer at March 31, 2022 and December 31, 2021, respectively: March 31, 2022 December 31, 2021 Sales Commissions App Store Fees Total Sales Commissions App Store Fees Total (In thousands) Current $ 42,794 $ 8,640 $ 51,434 $ 39,669 $ 9,023 $ 48,692 Non-current 5,987 — 5,987 6,086 — 6,086 Total $ 48,781 $ 8,640 $ 57,421 $ 45,755 $ 9,023 $ 54,778
Certain Risks and Concentrations - Services Agreement with Google (the "Services Agreement")	Certain Risks and Concentrations—Services Agreement with Google (the "Services Agreement")A meaningful portion of the Company's revenue (and a substantial portion of IAC's net cash from operating activities attributable to continuing operations that it can freely access) is attributable to the Services Agreement. In addition, the Company earns certain other advertising revenue from Google that is not attributable to the Services Agreement.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Not Yet Adopted by IAC There are no recently issued accounting pronouncements that have not yet been adopted 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. For the three months ended March 31, 2022, both the Company and Angi Inc. had a loss from operations and as a result these awards were excluded from computing dilutive earnings per share because the impact would have been anti-dilutive. For the three months ended March 31, 2021 it was more dilutive for IAC to settle these Angi Inc. equity awards. The impact on net earnings relates to the settlement of Angi Inc.'s dilutive securities in IAC common shares. (c) For the three months ended March 31, 2022, the Company had a loss from continuing operations and, as a result, approximately 7.8 million potentially dilutive securities 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 months ended March 31, 2022. (d)
