THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Separation

On December 19, 2019, IAC/InterActiveCorp ("IAC") entered into a Transaction Agreement (as amended as of April 28, 2020, the "Transaction Agreement") with Match Group, Inc. ("MTCH"), IAC Holdings, Inc., a direct wholly owned subsidiary of IAC ("New IAC" or the "Company"), and Valentine Merger Sub LLC, an indirect wholly owned subsidiary of IAC. Subject to the terms and conditions set forth in the Transaction Agreement, if the transactions contemplated by the Transaction Agreement are consummated, the businesses of MTCH will be separated from the remaining businesses of IAC through a series of transactions that will result in the pre-transaction stockholders of IAC owning shares in two, separate public companies—(1) IAC, which will be renamed Match Group, Inc. ("New Match") and which will own the businesses of MTCH and certain IAC financing subsidiaries, and (2) New IAC, which will be renamed IAC/InterActiveCorp and which will own IAC's other businesses—and the pre-transaction stockholders of MTCH (other than IAC) owning shares in New Match. Completion of the separation, which is expected to occur in the second quarter of 2020, is subject to a number of conditions, including approval by a majority of the disinterested shareholders of MTCH, approval of IAC’s shareholders and other customary conditions and approvals. This transaction is referred to as the "Separation".

Basis of Presentation and Combination

In connection with the Separation, IAC Holdings, Inc. was incorporated as a Delaware corporation in November 2019. IAC Holdings, Inc. does not engage in any business or other activities other than in connection with the Separation. In contemplation of the Separation: (1) effective January 1, 2020, all employees of the IAC/InterActiveCorp legal entity became employees of the IAC Holdings, Inc. legal entity and (2) during the first quarter of 2020, IAC contributed $1.1 billion in cash to IAC Holdings, Inc. in connection with the transfer of the centrally-managed U.S. treasury function from January 1, 2020 to IAC Holdings, Inc. The legal entity financial statements of IAC Holdings, Inc. are included in "Note 12 - IAC Holdings, Inc. Legal Entity Financial Statements".

The historical combined financial statements of IAC Holdings, Inc. and the businesses comprising New IAC have been derived from the consolidated financial statements and accounting records of IAC. The combined financial statements reflect the historical financial position, results of operations and cash flows of IAC Holdings, Inc. and the businesses comprising New IAC since their respective dates of acquisition by IAC and the allocation to New IAC of certain IAC corporate expenses relating to New IAC based on the historical financial statements and accounting records of IAC. For the purpose of these financial statements, income taxes have been computed as if the entities comprising New IAC filed tax returns on a standalone, separate basis. The financial statements have been prepared on a combined, rather than consolidated, basis as the final steps of the legal reorganization, which will result in the contribution of all the entities that will comprise New IAC as of the date of the Separation, are not yet complete.

As used herein, ‘‘New IAC,’’ the ‘‘Company,’’ ‘‘we,’’ ‘‘our’’ or ‘‘us’’ and similar terms in these historical combined financial statements refer to IAC Holdings, Inc. and the businesses comprising New IAC (unless the context requires otherwise).

The Company prepares its combined financial statements in accordance with U.S. generally accepted accounting principles (‘‘GAAP’’).

All intercompany transactions and balances between and among the Company and the entities comprising the Company have been eliminated. All intercompany transactions between (i) New IAC and (ii) IAC and its subsidiaries are considered to be effectively settled for cash at the time the transaction is recorded. The total net effect of the settlement of these intercompany transactions is reflected in the combined statement of cash flows as a financing activity and in the combined balance sheet as ‘‘Invested capital.’’

In management’s opinion, the assumptions underlying the historical combined financial statements of the Company, including the basis on which the expenses have been allocated from IAC, are reasonable. However, the allocations may not reflect the expenses that we may have incurred as an independent, stand-alone company for the periods presented.

The accompanying unaudited combined 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. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited combined financial statements include all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited interim combined financial statements should be read in conjunction with the annual audited combined financial statements of the Company and notes thereto for the year ended December 31, 2019.

COVID-19 Update

The Company's business could be materially and adversely affected by the outbreak of COVID-19, which has been declared a "pandemic" by the World Health Organization.

Through March 31, 2020, the Company's ANGI Homeservices business has experienced a decline in demand for home services requests, driven primarily by decreases in demand in certain categories of jobs (particularly non-essential projects) and decreases in demand in regions most affected by the COVID-19 outbreak, which the Company attributes both to the unwillingness of consumers to interact with service professionals face-to-face or have service professionals in their homes, and to lower levels of consumer confidence and discretionary income generally. In addition, with respect to the Company's ad-supported businesses, the Company has experienced a meaningful decrease in advertising rates across the Company's various properties (as much as 30% year over year).

In connection with the first quarter close of its books, the Company determined that the effects of COVID-19 were an indicator of possible impairment for certain of its assets. The Company determined, as of March 31, 2020, the fair value for those assets for which COVID-19 was deemed to be an indicator of possible impairment and identified the following impairments:


•	a $212.0 million impairment related to the goodwill of the Desktop reporting unit;


•	a $21.4 million impairment related to certain indefinite-lived intangible assets of the Desktop reporting unit;


•	a $51.5 million impairment of certain equity securities without readily determinable fair values; and


•	a $7.5 million impairment of a note receivable and a warrant related to certain investees.

The extent to which developments related to the COVID-19 outbreak 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 speed of contagion, the development and implementation of effective preventative measures and possible treatments, the scope of governmental and other restrictions on travel, non-essential services and other activity, and public reactions to these developments. For example, these developments and measures have resulted in rapid and adverse changes to the operating environment in which we do business, as well as significant uncertainty concerning the near and long term economic ramifications of the COVID-19 outbreak, which have adversely impacted our ability to forecast our results and respond in a timely and effective manner to trends related to the COVID-19 outbreak. The longer the global outbreak and measures designed to curb the spread of the virus continue to adversely affect levels of consumer confidence, discretionary spending and the willingness of consumers to interact with other consumers, vendors and service providers face-to-face (and in turn, adversely affect demand for the Company’s various products and services), the greater the adverse impact is likely to be on the Company’s business, financial condition and results of operations and the more limited will be the Company’s ability to try and make up for delayed or lost revenues.

Nature of Operations

The Company operates Vimeo, Dotdash and Care.com, among many other online businesses, and has majority ownership of ANGI Homeservices, which includes HomeAdvisor, Angie’s List and Handy.

ANGI Homeservices

Our ANGI Homeservices segment includes the North American (United States and Canada) and European businesses and operations of ANGI Homeservices Inc. (‘‘ANGI’’). On September 29, 2017, the Company’s HomeAdvisor business and Angie’s List Inc. (‘‘Angie’s List’’) combined under a new publicly traded company called ANGI Homeservices Inc. (the ‘‘Combination’’). At March 31, 2020, the Company’s economic interest and voting interest in ANGI were 84.9% and 98.3%, respectively.

ANGI Homeservices Inc. connects quality home service professionals across 500 different categories, from repairing and remodeling to cleaning and landscaping, with consumers. Approximately 250,000 domestic service professionals find work through ANGI and consumers turn to at least one of our brands to find a professional for more than 25 million projects each year. ANGI has established category-transforming products with brands such as HomeAdvisor, Angie’s List, Handy and Fixd Repair.

On January 25, 2019, ANGI completed the acquisition of Fixd Repair, a home warranty and service company. ANGI also owns and operates Handy, a leading platform in the United States for connecting individuals looking for household services (primarily cleaning and handyman services) with top-quality, pre-screened independent service professionals, and mHelpDesk, a provider of cloud-based field service software for small to mid-size businesses. In addition to its market-leading U.S. operations, ANGI owns leading home services online marketplaces in France (Travaux), Germany (MyHammer), Netherlands (Werkspot), United Kingdom (MyBuilder Limited or ‘‘MyBuilder,’’ which we acquired a controlling interest in on March 24, 2017), Canada (HomeStars Inc. or ‘‘HomeStars,’’ which we acquired a controlling interest in on February 8, 2017) and Italy (Instapro), as well as operations in Austria (MyHammer).

Vimeo

Vimeo operates a global video platform for creative professionals, small and medium businesses (‘‘SMBs’’), organizations and enterprises to connect with their audiences, customers and employees. Vimeo provides cloud-based Software-as-a-Service (‘‘SaaS’’) offerings that allow customers to create, host, stream, monetize, analyze and distribute videos online and across devices. Vimeo also sold live streaming accessories through its hardware business, which was sold on March 29, 2019.

On May 28, 2019, Vimeo completed the acquisition of Magisto, a video creation service enabling consumers and businesses to create short-form videos.

Accounting Estimates

Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its combined 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 contingent assets and liabilities. Actual results could differ from these estimates.

On an ongoing basis, the Company evaluates its estimates and judgments, including those related to: the fair values of cash equivalents and marketable debt securities; the carrying value of accounts receivable, including the determination of the allowance for doubtful accounts; the determination of revenue reserves; the carrying value of right-of-use assets ("ROU assets"); the useful lives and recoverability of definite-lived intangible assets and property, capitalized software and equipment; 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; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments 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 combined 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 Financial Liabilities, with any changes to fair value recognized within other income (expense), net 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; 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 reviews its investments in equity securities without readily determinable fair values for impairment each reporting period when there are qualitative factors or events that indicate possible impairment. Factors the Company considers in making this determination include negative changes in industry and market conditions, financial performance, business prospects, and other relevant events and factors. When indicators of impairment exist, the Company prepares quantitative assessments of the fair value of its investments in equity securities, which require judgment and the use of estimates. When the Company's assessment indicates that the fair value of the investment is below its carrying value, the Company writes down the investment to its fair value and records the corresponding charge within other income (expense), net. See "Note 5 - Financial Instruments and Fair Value Measurements" for additional information on the impairments of certain equity securities without readily determinable fair values recorded in the quarter ended March 31, 2020.

In the event the Company has 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, are accounted for using the equity method and are included in "Long-term investments" in the accompanying combined balance sheet. At March 31, 2020 and December 31, 2019, the Company did not have any investments accounted for using the equity method.

General Revenue Recognition

Revenue is recognized when control of the promised services or goods is transferred to the Company's customers and in the 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 8—Segment Information."

Prior to January 1, 2020, ANGI's Handy business recorded revenue on a net basis. Effective January 1, 2020, the Company modified the Handy terms and conditions so that Handy, rather than the service professional, has the contractual relationship with the consumer to deliver the service and Handy, rather than the consumer, has the contractual relationship with the service professional. Consumers request services and pay for such services directly through the Handy platform and then Handy fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. This change in contractual terms requires gross revenue accounting treatment effective January 1, 2020. Also, in the case of certain tasks, HomeAdvisor provides a pre-priced product offering, pursuant to which consumers can request services through a HomeAdvisor platform and pay HomeAdvisor for the services directly. HomeAdvisor then fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. Revenue from HomeAdvisor’s pre-priced product offering is also recorded on a gross basis effective January 1, 2020. In addition to changing the presentation of revenue to gross from net, the timing of revenue recognition will change for pre-priced jobs and will be later than the timing of existing consumer connection revenue for HomeAdvisor because the Company will not be able to record revenue, generally, until the service professional completes the job on the Company's behalf. The change to gross revenue reporting for Handy and HomeAdvisor’s pre-priced product offering, effective January 1, 2020, resulted in an increase in revenue of $15.2 million during the three months ended March 31, 2020.

Deferred Revenue

Deferred revenue consists of advance payments that are received or are contractually due in advance of the Company's performance. 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 term of the applicable subscription period or expected completion of the Company's performance obligation is one year or less. The current and non-current deferred revenue balances at December 31, 2019 are $178.6 million and $1.3 million, respectively. During the three months ended March 31, 2020, the Company recognized $90.9 million of revenue that was included in the deferred revenue balance as of December 31, 2019. During the three months ended March 31, 2019, the Company recognized $76.0 million of revenue that was included in the deferred revenue balance as of December 31, 2018. The current and non-current deferred revenue balances at March 31, 2020 are $215.7 million and $1.3 million, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying combined 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 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 the Company has the right to invoice for services performed.

For sales incentive programs where the customer relationship period is one year or less, the Company has elected the practical expedient to expense the costs as incurred. The amount of capitalized sales commissions where the customer relationship period is greater than one year is $47.5 million and $42.4 million at March 31, 2020 and December 31, 2019, respectively.

Allowance for Doubtful Accounts and Revenue Reserve

The following table presents the changes in the allowance for doubtful accounts for three months ended March 31, 2020:



	Three Months Ended March 31, 2020
	(In thousands)
Balance at January 1	$	20,257
Current period provision of bad debt	19,193
Write-offs charged against the allowance	(16,528		)
Recoveries collected	736
Balance at March 31	$	23,658

The revenue reserve was $4.4 million and $3.9 million at March 31, 2020 and December 31, 2019, respectively. The total allowance for doubtful accounts and revenue reserve was $28.1 million and $24.1 million as of March 31, 2020 and December 31, 2019, respectively.

Certain Risks and Concentrations—Services Agreement with Google

IAC and Google are party to a services agreement (the "Services Agreement"). If the Separation is consummated, IAC shall assign the Services Agreement to the Company. A meaningful portion of the Company's revenue 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, 2020 and 2019, total revenue earned from Google was $138.9 million and $195.8 million, representing 20% and 31%, respectively, of the Company's combined revenue. Accounts receivable related to revenue earned from Google totaled $48.7 million and $53.0 million at March 31, 2020 and December 31, 2019, respectively.

Revenue attributable to the Services Agreement is earned by the Desktop business within the Applications segment and by the Ask Media Group segment. For the three months ended March 31, 2020 and 2019, revenue earned from the Services Agreement was $46.1 million and $88.1 million, respectively, within the Applications segment and $80.5 million and $94.8 million, respectively, within the Ask Media Group segment.

The current Services Agreement was scheduled to expire on March 31, 2020. On February 11, 2019, IAC and Google amended the Services Agreement, effective as of April 1, 2020. The amendment extends the expiration date of the agreement to March 31, 2023; provided that during September 2020 and during each September thereafter, either party may, after discussion with the other party, terminate the Services Agreement, effective on September 30 of the year following the year such notice is given. IAC believes that the amended agreement, taken as a whole, is comparable to the pre-amendment agreement with Google. 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 could in turn require modifications to, or prohibit and/or render obsolete certain of the Company's products, services and/or business practices, which could be costly to address or otherwise have an adverse effect on the Company's combined financial condition and results of operations, particularly the Desktop business and Ask Media Group. From time to time, 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 and Google may do so in the future.

Adoption of New Accounting Pronouncements

Adoption of ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments

The Company adopted ASU No. 2016-13 effective January 1, 2020. The standard significantly changes how entities measure credit losses for most financial assets, including accounts receivable. ASU No. 2016-13 replaces the “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. The Company adopted ASU No. 2016-13 using the modified retrospective approach and there was no cumulative effect arising from the adoption. The adoption of ASU No. 2016-13 did not have a material impact on the Company's combined financial statements.

Adoption of ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes

The Company adopted ASU No. 2019-12 effective January 1, 2020, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. Most amendments within ASU No. 2019-12 are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. The Company adopted ASU No. 2019-12 on January 1, 2020 using the modified retrospective basis for those amendments that are not applied on a prospective basis. The adoption of ASU No. 2019-12 did not have a material impact on the Company's combined financial statements.

Income Tax Disclosure [Abstract]

INCOME TAXES

The Company is included within IAC’s tax group for purposes of federal and consolidated state income tax return filings. In all periods presented, current and deferred income tax benefit/provision have been computed for the entities comprising the Company on an as if standalone, separate return basis and payments to and refunds from IAC for the Company’s share of IAC’s consolidated federal and state tax return liabilities/receivables calculated on this basis have been reflected within cash flows from operating activities in the accompanying combined statements of cash flows.

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 in the quarter in which the change occurs.

We have calculated the provision for income taxes during the March 31, 2020 period by applying an estimate of the annual effective tax rate for the full fiscal year to ordinary loss (pretax loss excluding unusual or infrequently occurring discrete items) for the reporting period. We have used a discrete effective tax rate method to calculate domestic taxes for the three months ended March 31, 2019. We determined that since small changes in estimated ordinary income would result in significant changes in the estimated annual effective tax rate, the historical method would not provide a reliable estimate for the three months ended March 31, 2019.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was signed into law. The CARES Act provides opportunities for additional liquidity, loan guarantees, and other government programs to support companies affected by the COVID-19 pandemic and their employees. Based on the Company's preliminary analysis of the CARES Act, New IAC expects to avail itself of the following:


•	a refund of federal income taxes due to a five-year carryback of net operating loss incurred in 2019;


•	accelerated depreciation deductions; and


•	a deferral of 2020 employer social security payroll taxes.

The Company continues to review and consider worldwide government programs related to the COVID-19 pandemic; however, the Company does not expect the impact of these programs to be material.

For the three months ended March 31, 2020, the Company recorded an income tax benefit of $41.4 million which represents an effective income tax rate of 11%. The effective income tax rate is lower than the statutory rate of 21% due primarily to the non-deductible portion of Desktop goodwill impairment charge and unbenefited losses related to other investments, partially offset by a revaluation of net operating loss deferred taxes due to the CARES Act. For the three months ended March 31, 2019, the Company recorded an income tax benefit of $29.2 million which represents an effective income tax rate of 68%. The effective income tax rate is higher than the statutory rate of 21% due primarily to excess tax benefits generated by the exercise and vesting of stock-based awards.

Upon the Separation, the Company will be allocated a portion of tax attributes related to the IAC consolidated federal and state tax filings pursuant to the Internal Revenue Code and applicable state law. This allocation will require that the Company’s net deferred tax liability (computed on an as if standalone, separate return basis) be adjusted as of the Separation date with a corresponding adjustment to additional paid-in capital. The final allocation of tax attributes and resulting adjustment to the Company’s deferred taxes will be impacted by multiple factors, including, but not limited to, the ultimate date of the Separation and the amount of taxable income or loss generated by the IAC consolidated tax group in the year of the Separation.

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 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 IAC. 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 IAC’s federal income tax returns for the years ended December 31, 2010 through 2016, which includes the operations of the Company, resulting in reductions to the research credits claimed. The IRS is expected to begin an audit of the year ended December 31, 2017 in the second quarter of 2020. The statute of limitations for the years 2010 through 2012 has been extended to November 30, 2020 and the statute of limitations for the years 2013 through 2016 has been extended to March 31, 2021. Returns filed in various other jurisdictions are open to examination for tax years beginning with 2009. Income taxes payable include unrecognized tax benefits considered sufficient to pay assessments that may result from 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 March 31, 2020 and December 31, 2019, unrecognized tax benefits, including interest and penalties, are $16.7 million and $20.3 million, respectively. Unrecognized tax benefits, including interest and penalties, at March 31, 2020 decreased by $3.6 million due primarily to the effective settlement of certain prior year tax positions with the IRS relating to research credits. If unrecognized tax benefits at March 31, 2020 are subsequently recognized, $15.3 million, net of related deferred tax assets and interest, would reduce income tax expense. The comparable amount as of December 31, 2019 was $18.9 million. The Company believes it is reasonably possible that its unrecognized tax benefits could decrease by $6.4 million by March 31, 2021, due primarily to expirations of statutes of limitations and other settlements, $6.2 million of which would reduce the income tax provision.

BUSINESS COMBINATION

Care.com

On February 11, 2020, IAC acquired 100% of Care.com, a leading global platform for finding and managing family care, for a total purchase price of $627.5 million, which includes cash consideration of $587.0 million paid by the Company and the settlement of all outstanding vested employee equity awards for $40.5 million paid by Care.com prior to the completion of the acquisition. The Company's purchase accounting is not yet complete, including the determination of purchase price and the allocation of purchase price to the fair value of assets acquired and liabilities assumed. These preliminary values are subject to revision and are not expected to be finalized until the fourth quarter of 2020.

The financial results of Care.com are included in the Company's combined financial statements, within the Emerging & Other segment, beginning February 11, 2020. For the three months ended March 31, 2020, the Company included $18.5 million of revenue and $12.3 million of net loss in its combined statement of operations related to Care.com. The net loss of Care.com reflects a reduction in revenue of $8.7 million due to the write-off of deferred revenue related to the acquisition and $4.8 million in transaction-related costs, including severance.

The table below summarizes the preliminary estimated fair values of the assets acquired and liabilities assumed at the date of acquisition:



	Care.com
	(In thousands)
Cash and cash equivalents	$	57,873
Short-term investments	20,000
Accounts receivable	20,292
Other current assets	5,678

Other current liabilities	(36,400		)
Deferred income taxes	(33,960		)
Other non-current liabilities	(25,001		)
Net assets acquired	$	586,975

IAC acquired Care.com because it is complementary to other marketplace businesses of New IAC. The purchase price was based on the expected financial performance of Care.com, not on the value of the net identifiable assets at the time of acquisition. This resulted in a significant portion of the purchase price being attributed to goodwill.

The preliminary estimated fair values of the identifiable intangible assets acquired at the date of acquisition are as follows:



	Care.com
	(In thousands)		Useful Life (Years)
Indefinite-lived trade name and trademarks	$	59,400	Indefinite
Developed technology	49,700		5
Customer relationships	35,400		2 - 7
Provider relationships	800		4
Total identifiable intangible assets acquired	$	145,300

Other current assets, other non-current assets, other current liabilities and other non-current liabilities of Care.com were reviewed and adjusted to their fair values at the date of acquisition, as necessary. The fair values of the trade name and developed technology were determined using an income approach that utilized the relief from royalty methodology. The fair values of customer relationships and provider relationships were determined using an income approach that utilized the excess earnings methodology. The valuations of the intangible assets incorporate significant unobservable inputs and require significant judgment and estimates, including the amount and timing of future cash flows and the determination of royalty and discount rates. The amount attributed to goodwill is not tax deductible.

Unaudited pro forma financial information

The unaudited pro forma financial information in the table below presents the combined results of the Company and Care.com as if this acquisition had occurred on January 1, 2019. 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 the acquisition actually occurred on January 1, 2019. For the three months ended March 31, 2020, pro forma adjustments include a reduction in transaction related costs (including stock-based compensation expense related to the acceleration of vesting of outstanding employee equity awards) of $60.9 million because they are one-time in nature and will not have a continuing impact on operations and an increase in revenue of $8.7 million related to deferred revenue written off as a part of the acquisition. For the three months ended March 31, 2019, pro forma adjustments include an increase in amortization of intangibles of $4.0 million and a decrease of $7.7 million related to the deferred revenue written off as a part of the acquisition.

Additions are related to the acquisition of Care.com (included in Emerging & Other Segment).

In connection with the first quarter close of its books, the Company determined that the effects of COVID-19 were an indicator of possible impairment for certain of its reporting units and indefinite-lived intangible assets. The Company determined the fair value of these reporting units and indefinite-lived intangible assets as of March 31, 2020 and identified the following impairments:


•	a $212.0 million impairment related to the goodwill of the Desktop reporting unit and

•a $21.4 million impairment related to certain indefinite-lived intangible assets of the Desktop reporting unit.

In addition, the updated valuation of the Mosaic Group reporting unit indicates that the fair value of this reporting unit approximates its carrying value. The goodwill of the Desktop and Mosaic Group reporting units is $53.2 million and $239.5 million, respectively, as of March 31, 2020. To the extent there is a decline in the fair value of these reporting units, a goodwill impairment would be recorded to the extent the carrying value exceeds the fair value.

The fair value of the Desktop and Mosaic Group reporting units 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 forecasts for Desktop and Mosaic Group for 2020 and each of the years in the forecast period, which were updated in light of COVID-19. For years beyond the forecast period, Desktop and Mosaic Group estimates were based, in part, on forecasted growth rates. The discount rates used in the DCF analyses were intended to reflect the risks inherent in the expected future cash flows of the Desktop and Mosaic Group reporting units. The discount rate used for determining the fair value of both the Desktop and Mosaic Group reporting units was 15.0%. 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 Desktop and Mosaic Group reporting units. To determine a peer group of companies for Desktop and Mosaic Group, the Company considered companies relevant in terms of consumer use, monetization model, margin and growth characteristics, and brand strength operating in their respective sectors. The aggregate carrying value of goodwill for which the most recent estimate of the excess of fair value over carrying value is less than 20% is approximately $709.4 million.

The following table presents the balance of goodwill by reportable segment, including the changes in the carrying value of goodwill, for the year ended December 31, 2019:



	Balance at December 31, 2018		Additions		(Deductions)			Impairment			Foreign Exchange Translation			Balance at December 31, 2019

Additions primarily relate to the acquisitions of Magisto (included in the Vimeo segment) and Fixd Repair (included in the ANGI Homeservices segment). Deductions primarily relate to tax benefits of acquired attributes related to the acquisition of Handy (included in the ANGI Homeservices segment). During the fourth quarter of 2019, the Company recorded an impairment charge of $3.3 million related to the goodwill of the College Humor Media business (included in the Emerging & Other Segment).

The March 31, 2020 and December 31, 2019 goodwill balances reflect accumulated impairment losses of $741.1 million and $529.1 million, respectively, at Applications. The March 31, 2020 and December 31, 2019 goodwill balances also reflect accumulated impairment losses of $212.6 million, $198.3 million, $187.1 million and $14.9 million at the businesses previously included in the IAC Publishing segment (excluding Dotdash and Ask Media Group, included in the Emerging & Other segment), Dotdash, Ask Media Group and College Humor Media (included in the Emerging & Other segment), respectively.

As described above, since the effects of COVID-19 were an indicator of impairment, the Company updated its calculations of the fair value of its indefinite-lived intangible assets as of March 31, 2020. The Company recorded impairment charges of $21.4 million at Desktop, related to indefinite-lived trade names. The impairment of indefinite-lived intangible assets is included in “Amortization of intangibles” in the accompanying combined 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 rates used in the DCF analyses were intended to reflect the risks inherent in the expected future cash flows generated by the respective intangible assets. The royalty rates used in the DCF analyses were based upon an estimate of the royalty rates that a market participant would pay to license the Company's trade names and trademarks. The discount rate used to value the trade names that were impaired in the first quarter of 2020 was 15.0% and the royalty rate was 1.0%. The aggregate carrying value of indefinite-lived intangible assets for which the most recent estimate of the excess of fair value over carrying value is less than 20% is approximately $70.2 million.

At March 31, 2020 and December 31, 2019, intangible assets with definite lives are as follows:

Equity Securities Without Readily Determinable Fair Values

At March 31, 2020 and December 31, 2019, the carrying values of the Company's investments in equity securities without readily determinable fair values totaled $296.5 million and $348.0 million, respectively, and are included in "Long-term investments" in the accompanying combined balance sheet. During the first quarter of 2020, the Company recorded unrealized impairments of $51.5 million related to certain equity securities without readily determinable fair values due to the impact of COVID-19. All gains and losses on equity securities without readily determinable fair values, realized and unrealized, are recognized in "Other expense, net" in the accompanying combined statement of operations.

The following table presents a summary of unrealized gains and losses recorded in "Other expense, net," as adjustments to the carrying value of equity securities without readily determinable fair values held as of March 31, 2020 and 2019.

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:

Warrant

As part of the Company's investment in Turo, a peer-to-peer car sharing marketplace, the Company received a warrant that is net settleable at the Company's option and is recorded at fair value each reporting period with any change included in "Other expense, net" in the accompanying combined 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 accompanying combined balance sheet.

Contingent Consideration Arrangements

At March 31, 2020, the Company has one outstanding contingent consideration arrangement related to a business acquisition. The arrangement has a remaining total maximum contingent payment of $30.0 million. At March 31, 2020, the gross fair value of this arrangement, before unamortized discount, is $1.3 million. In connection with the Care.com acquisition on February 11, 2020, the Company assumed a contingent consideration arrangement liability of $1.0 million, which was subsequently paid during the first quarter of 2020.

Generally, our contingent consideration arrangements are based upon financial performance and/or operating metric targets and the Company generally determines the fair value of the contingent consideration arrangements by using probability-weighted analyses to determine the amounts of the gross liability, and, if the arrangements are initially long-term in nature, applying a discount rate that appropriately captures the risks associated with the obligations to determine the net amount reflected in the combined financial statements. The fair values of the contingent consideration arrangement at March 31, 2020 and December 31, 2019 reflect a discount rate of 25%.

The fair value of contingent consideration arrangements is sensitive to changes in the expected achievement of the applicable targets and changes in discount rates. The Company remeasures the fair value of the contingent consideration arrangements each reporting period, including the accretion of the discount, if applicable, and changes are recognized in "General and administrative expense" in the accompanying combined statement of operations. The contingent consideration arrangement liability at March 31, 2020 and December 31, 2019 includes a non-current portion of $0.6 million and $6.9 million, respectively. The non-current portion of the contingent consideration liability is included in “Other long-term liabilities” in the accompanying combined balance sheet.

Assets measured at fair value on a nonrecurring basis

The Company's non-financial assets, such as goodwill, intangible assets, ROU assets and property, capitalized software 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. See "Note 4—Goodwill and Intangible Assets" for a detailed description of the Desktop goodwill and indefinite-lived intangible asset impairments recorded in the quarter ended March 31, 2020.

Financial instruments measured at fair value only for disclosure purposes

ANGI Term Loan and ANGI Credit Facility

The outstanding balance of the loan ("ANGI Term Loan") was $244.1 million and $247.5 million at March 31, 2020 and December 31, 2019, respectively. There are quarterly principal payments of $3.4 million through December 31, 2021, $6.9 million for the one-year period ending December 31, 2022 and $10.3 million through maturity of the loan when the final amount of $161.6 million is due. Additionally, interest payments are due at least quarterly through the term of the loan. At both March 31, 2020 and December 31, 2019, the ANGI Term Loan bore interest at LIBOR plus 1.50%, or 2.28% and 3.25%, respectively. The spread over LIBOR is subject to change in future periods based on ANGI's consolidated net leverage ratio.

The terms of the ANGI Term Loan require ANGI to maintain a consolidated net leverage ratio of not more than 4.5 to 1.0 and a minimum interest coverage ratio of not less than 2.0 to 1.0 (in each case as defined in the credit agreement). The ANGI Term Loan also contains covenants that would limit ANGI's ability to pay dividends, make distributions or repurchase its stock in the event a default has occurred or ANGI's consolidated net leverage ratio exceeds 4.25 to 1.0. At March 31, 2020, there were no limitations pursuant thereto. There are additional covenants under the ANGI Term Loan that limit the ability of ANGI and its subsidiaries to, among other things, incur indebtedness, pay dividends or make distributions.

The $250 million revolving credit facility (the "ANGI Credit Facility") expires on November 5, 2023. At March 31, 2020 and December 31, 2019, there were no outstanding borrowings under the ANGI Credit Facility. The annual commitment fee on undrawn funds is based on the consolidated net leverage ratio most recently reported and was 25 basis points at both March 31, 2020 and December 31, 2019. Borrowings under the ANGI Credit Facility bear interest, at ANGI's option, at either a base rate or LIBOR, in each case plus an applicable margin, which is based on ANGI's consolidated net leverage ratio. The financial and other covenants are the same as those for the ANGI Term Loan.

The ANGI Term Loan and ANGI Credit Facility are guaranteed by ANGI's wholly-owned material domestic subsidiaries and are secured by substantially all assets of ANGI and the guarantors, subject to certain exceptions.

IAC Group Credit Facility

IAC Group, LLC ("IAC Group") is the borrower under the IAC Credit Facility. IAC Group is included within these combined financial statements and will become a subsidiary of New IAC upon consummation of the Separation.

At March 31, 2020, IAC Group has a $250 million revolving credit facility (the "IAC Group Credit Facility"), that expires on November 5, 2023. At March 31, 2020 and December 31, 2019, there were no outstanding borrowings under the IAC Group Credit Facility. The annual commitment fee on undrawn funds is based on the consolidated net leverage ratio (as defined in the agreement) most recently reported and was 20 basis points at both March 31, 2020 and December 31, 2019. Borrowings under the IAC Group Credit Facility bear interest, at IAC Group's option, at a base rate or LIBOR, in each case, plus an applicable margin, which is based on IAC Group's consolidated net leverage ratio. The terms of the IAC Group Credit Facility require that IAC Group maintains a consolidated net leverage ratio of not more than 3.25 to 1.0 before the date on which IAC Group no longer holds majority of the outstanding voting stock of ANGI (the "Trigger Date") and no greater than 2.75 to 1.0 on or after the Trigger Date. The terms of the IAC Group Credit Facility also restrict IAC Group's ability to incur additional indebtedness. Borrowings under the IAC Group Credit Facility are unconditionally guaranteed by certain of our wholly-owned domestic subsidiaries and are also secured by the stock of certain of our domestic and foreign subsidiaries, including the shares of Match Group and ANGI owned by IAC Group. Following the Separation, Match Group shares will no longer be pledged as collateral to secure the IAC Group Credit Facility.

Segment Reporting [Abstract]

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: how the chief operating decision maker views the businesses; 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.

_____________________

^(a)

The Company's primary financial measure is Adjusted EBITDA, which is defined as operating income excluding: (1) stock-based compensation expense; (2) depreciation; and (3) acquisition-related items consisting of (i) amortization of intangible assets and impairments of goodwill and intangible assets, if applicable, and (ii) gains and losses recognized on changes in the fair value of contingent consideration arrangements. The Company believes this measure is useful for analysts and investors as this measure allows a more meaningful comparison between the Company's performance and that of its competitors. The above items are excluded from the Company's Adjusted EBITDA measure because these items are non-cash in nature. Adjusted EBITDA has certain limitations because it excludes the impact of these expenses.

The following tables reconcile operating (loss) income for the Company's reportable segments and net loss attributable to IAC/InterActiveCorp equity in IAC Holdings, Inc. to Adjusted EBITDA:

CONTINGENCIES	3 Months Ended
CONTINGENCIES	Mar. 31, 2020
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. Tinder Optionholder Litigation against IAC and Match Group On August 14, 2018, ten then-current and former employees of Match Group, LLC or Tinder, Inc. ("Tinder"), an operating business of Match Group, filed a lawsuit in New York state court against IAC and Match Group. See Sean Rad et al. v. IAC/InterActiveCorp and Match Group, Inc., No. 654038/2018 (Supreme Court, New York County). The complaint alleges that in 2017, the defendants: (i) wrongfully interfered with a contractually established process for the independent valuation of Tinder by certain investment banks, resulting in a substantial undervaluation of Tinder and a consequent underpayment to the plaintiffs upon exercise of their Tinder stock options, and (ii) then wrongfully merged Tinder into Match Group, thereby depriving certain of the plaintiffs of their contractual right to later valuations of Tinder on a stand-alone basis. The complaint asserts claims for breach of contract, breach of the implied covenant of good faith and fair dealing, unjust enrichment, interference with contractual relations (as against Match Group only), and interference with prospective economic advantage, and seeks compensatory damages in the amount of at least $2 billion, as well as punitive damages. On August 31, 2018, four plaintiffs who were still employed by Match Group filed a notice of discontinuance of their claims without prejudice, leaving the six former employees as the remaining plaintiffs. On October 9, 2018, the defendants filed a motion to dismiss the complaint on various grounds, including that the 2017 valuation of Tinder by the investment banks was an expert determination any challenge to which is both time-barred under applicable law and available only on narrow substantive grounds that the plaintiffs have not pleaded in their complaint; the plaintiffs opposed the motion. On June 13, 2019, the court issued a decision and order (i) granting the motion to dismiss the claims for breach of the implied covenant of good faith and fair dealing and for unjust enrichment, (ii) granting the motion to dismiss the merger-related claim for breach of contract as to two of the remaining six plaintiffs, and (iii) otherwise denying the motion to dismiss. On June 21, 2019, the defendants filed a notice of appeal from the trial court’s partial denial of their motion to dismiss, and the parties thereafter briefed the appeal. On October 29, 2019, the Appellate Division, First Department, issued an order affirming the lower court’s decision. On November 22, 2019, the defendants filed a motion for reargument or, in the alternative, leave to appeal the Appellate Division's order to the New York Court of Appeals; the plaintiffs opposed the motion. On May 21, 2020, the Appellate Division issued an order (i) granting the defendants’ motion for reargument, vacating its prior decision, and replacing it with a new decision that affirmed the lower court’s decision on different grounds, and (ii) denying the defendants’ motion for leave to appeal the initial (and now vacated) decision to the Court of Appeals, without prejudice to the defendants’ filing a motion for leave to appeal the new decision to the Court of Appeals. On June 3, 2019, the defendants filed a second motion to dismiss based upon certain provisions of the plaintiffs' agreement with a litigation funding firm; the plaintiffs opposed the motion, which remains pending. Document discovery in the case is substantially complete; deposition discovery has begun but is currently in hiatus in light of the COVID-19 pandemic. On January 30, 2020, the parties participated in a mediation that did not result in resolution of the matter. IAC and Match Group believe that the allegations against them in this lawsuit are without merit and will continue to defend vigorously against it. Pursuant to the Transaction Agreement, Match Group has agreed to indemnify the Company for matters relating to any business of Match Group, including indemnifying the Company for costs related to the matter described above.

RELATED PARTY TRANSACTIONS

Relationship with IAC prior to the Separation

New IAC’s combined statement of operations includes allocations of costs, including stock-based compensation expense, related to IAC’s accounting, treasury, legal, tax, corporate support and internal audit functions. To the extent applicable, IAC has historically allocated costs related to its accounting, treasury, legal, tax, corporate support and internal audit functions that are incurred at the IAC/InterActiveCorp legal entity level to its publicly traded subsidiaries, Match Group and ANGI Homeservices, based upon time spent or other cost drivers, such as revenue, number of legal entities or transaction volume, in their standalone financial statements. For periods subsequent to the Match Group IPO in November 2015 and the Combination in September 2017, IAC billed Match Group and ANGI Homeservices for any services provided under the applicable services agreements. The remaining unallocated expenses of IAC/InterActiveCorp related to its accounting, treasury, legal, tax, corporate support and internal audit functions were allocated to New IAC based upon time spent or other cost drivers, such as revenue, number of legal entities or transaction volume. Allocated costs, inclusive of stock-based compensation expense, were $24.0 million, and $35.5 million, for the three months ended March 31, 2020 and 2019, respectively. It is not practicable to determine the actual expenses that would have been incurred for these services had New IAC operated as a standalone entity during the periods presented. Management considers the allocation method to be reasonable.

The portion of interest income reflected in the combined statement of operations that is related party in nature, was less than $0.1 million for the three months ended March 31, 2020 and is included in ‘‘Interest income, net’’ in the table below.

The following table summarizes the components of the net (increase) decrease in IAC’s investment in IAC Holdings, Inc. for the three months ended March 31, 2020 and 2019:

Notes Receivable—Related Party

During 2019, New IAC, through two domestic subsidiaries, entered into loan agreements with IAC for cash transfers to IAC under its centrally managed U.S. treasury function. During the first quarter of 2020, the outstanding balance, which was $55.3 million at December 31, 2019, was repaid.

On February 11, 2020, New IAC, through a domestic subsidiary, entered into a loan agreement with IAC for cash transfers to IAC under its centrally managed U.S. treasury function. The outstanding receivable at March 31, 2020 is $27.2 million and bears interest at a rate per annum equal to the Monthly Short-Term Applicable Federal Rate and is due on demand. The interest rate at March 31, 2020 was 1.49%.

Long-term Debt—Related Party

On December 14, 2018, New IAC, through a domestic subsidiary, entered into a loan agreement with IAC for an amount not to exceed $15.0 million for general working capital purposes in the ordinary course of business. During the first quarter of 2019, the outstanding balance, which was $2.5 million at December 31, 2018, was repaid.

Guarantee of IAC Senior Notes

On December 21, 2012, IAC issued $500.0 million aggregate principal amount of 4.75% Senior Notes due December 15, 2022 (‘‘4.75% Senior Notes’’). On August 23, 2019, IAC redeemed the 4.75% Senior Notes and repaid the outstanding balance of $34.5 million. The 4.75% Senior Notes were unconditionally guaranteed by certain of New IAC’s domestic subsidiaries. New IAC did not pay any amount (or record any liability) as a result of our guarantee of IAC’s Senior Notes.

Relationship with IAC/New Match following the Separation

If the Separation is consummated, New IAC shall enter into certain agreements with IAC/New Match to govern the relationship between New IAC and IAC following the Separation. These agreements will include: a tax sharing agreement; a services agreement; and an employee matters agreement.

New IAC and ANGI

IAC and ANGI, in connection with the Combination, entered into a contribution agreement; an investor rights agreement; a services agreement; a tax sharing agreement; and an employee matters agreement. If the Separation is consummated, IAC shall assign these agreements to New IAC.

For the three months ended March 31, 2020 and 2019, 0.2 million and 0.3 million shares, respectively, of ANGI Class B common stock were issued to IAC pursuant to the employee matters agreement as reimbursement for shares of IAC common stock issued in connection with the exercise and vesting of IAC equity awards held by ANGI employees.

For the three months ended March 31, 2020 and 2019, ANGI was charged $1.2 million and $1.4 million, respectively, by IAC for services rendered pursuant to the services agreement. There were no outstanding receivables or payables pursuant to the services agreement as of March 31, 2020 or December 31, 2019.

New IAC and Match Group

For the three months ended March 31, 2020 and 2019, Match Group incurred rent expense of $0.8 million and $1.4 million, respectively, for the leasing of office space for certain of its businesses at properties owned by New IAC. The respective amounts were paid in full by Match Group at March 31, 2020 and December 31, 2019, respectively.

On January 31, 2020, IAC contributed two office buildings in Los Angeles to Match Group, which are primarily occupied and were previously leased from New IAC by Tinder. In connection with the contribution, New IAC entered into a lease with Match Group for office space which New IAC currently occupies in one of the buildings and for the three months ended March 31, 2020, New IAC paid Match Group less than $0.1 million under the lease. Match Group issued 1.4 million shares of Match Group common stock for the buildings.

New IAC and Expedia

Each of New IAC and Expedia has a 50% ownership interest in two aircraft that may be used by both companies. New IAC and Expedia purchased an aircraft during the second quarter of 2017 to replace a previously owned aircraft, which was subsequently sold on February 13, 2018. New IAC paid $17.4 million (50% of the total purchase price and refurbish costs) for its interest in the new aircraft. In addition, in 2019, New IAC and Expedia entered into an agreement to jointly acquire a new corporate aircraft for a total expected cost of $72.3 million (including purchase price and related costs), with each company to bear 50% of such expected cost. New IAC paid approximately $23 million in 2019 in connection with our joint entry into the purchase agreement, and the respective share of the balance is due upon delivery of the new aircraft, which is expected to occur in the second quarter of 2021. Members of the aircraft flight crews are employed by an entity in which each of New IAC and Expedia has a 50% ownership interest. New IAC 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. IAC and Expedia are related parties since they are under common control, given that Mr. Diller serves as Chairman and Senior Executive of both IAC and Expedia and subsequent to the Separation will serve as Chairman and Senior Executive of New IAC. For the three months ended March 31, 2020 and 2019, total payments made to this entity by New IAC were not material.

THE COMPANY AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	3 Months Ended
	Mar. 31, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Combination In connection with the Separation, IAC Holdings, Inc. was incorporated as a Delaware corporation in November 2019. IAC Holdings, Inc. does not engage in any business or other activities other than in connection with the Separation. In contemplation of the Separation: (1) effective January 1, 2020, all employees of the IAC/InterActiveCorp legal entity became employees of the IAC Holdings, Inc. legal entity and (2) during the first quarter of 2020, IAC contributed $1.1 billion in cash to IAC Holdings, Inc. in connection with the transfer of the centrally-managed U.S. treasury function from January 1, 2020 to IAC Holdings, Inc. The legal entity financial statements of IAC Holdings, Inc. are included in "Note 12 - IAC Holdings, Inc. Legal Entity Financial Statements". The historical combined financial statements of IAC Holdings, Inc. and the businesses comprising New IAC have been derived from the consolidated financial statements and accounting records of IAC. The combined financial statements reflect the historical financial position, results of operations and cash flows of IAC Holdings, Inc. and the businesses comprising New IAC since their respective dates of acquisition by IAC and the allocation to New IAC of certain IAC corporate expenses relating to New IAC based on the historical financial statements and accounting records of IAC. For the purpose of these financial statements, income taxes have been computed as if the entities comprising New IAC filed tax returns on a standalone, separate basis. The financial statements have been prepared on a combined, rather than consolidated, basis as the final steps of the legal reorganization, which will result in the contribution of all the entities that will comprise New IAC as of the date of the Separation, are not yet complete. As used herein, ‘‘New IAC,’’ the ‘‘Company,’’ ‘‘we,’’ ‘‘our’’ or ‘‘us’’ and similar terms in these historical combined financial statements refer to IAC Holdings, Inc. and the businesses comprising New IAC (unless the context requires otherwise). The Company prepares its combined financial statements in accordance with U.S. generally accepted accounting principles (‘‘GAAP’’). All intercompany transactions and balances between and among the Company and the entities comprising the Company have been eliminated. All intercompany transactions between (i) New IAC and (ii) IAC and its subsidiaries are considered to be effectively settled for cash at the time the transaction is recorded. The total net effect of the settlement of these intercompany transactions is reflected in the combined statement of cash flows as a financing activity and in the combined balance sheet as ‘‘Invested capital.’’ In management’s opinion, the assumptions underlying the historical combined financial statements of the Company, including the basis on which the expenses have been allocated from IAC, are reasonable. However, the allocations may not reflect the expenses that we may have incurred as an independent, stand-alone company for the periods presented. The accompanying unaudited combined 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. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, the accompanying unaudited combined financial statements include all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation. Interim results are not necessarily indicative of the results that may be expected for the full year. The accompanying unaudited interim combined financial statements should be read in conjunction with the annual audited combined financial statements of the Company and notes thereto for the year ended December 31, 2019.
Nature of Operations	Nature of Operations The Company operates Vimeo, Dotdash and Care.com, among many other online businesses, and has majority ownership of ANGI Homeservices, which includes HomeAdvisor, Angie’s List and Handy.
Accounting Estimates	Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its combined 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 contingent assets and liabilities. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates and judgments, including those related to: the fair values of cash equivalents and marketable debt securities; the carrying value of accounts receivable, including the determination of the allowance for doubtful accounts; the determination of revenue reserves; the carrying value of right-of-use assets ("ROU assets"); the useful lives and recoverability of definite-lived intangible assets and property, capitalized software and equipment; 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; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.
Accounting for Investments and Equity Securities	Accounting for Investments in Equity Securities Investments in equity securities, other than those of the Company's combined 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 Financial Liabilities, with any changes to fair value recognized within other income (expense), net 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; 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 reviews its investments in equity securities without readily determinable fair values for impairment each reporting period when there are qualitative factors or events that indicate possible impairment. Factors the Company considers in making this determination include negative changes in industry and market conditions, financial performance, business prospects, and other relevant events and factors. When indicators of impairment exist, the Company prepares quantitative assessments of the fair value of its investments in equity securities, which require judgment and the use of estimates. When the Company's assessment indicates that the fair value of the investment is below its carrying value, the Company writes down the investment to its fair value and records the corresponding charge within other income (expense), net. See "Note 5 - Financial Instruments and Fair Value Measurements" for additional information on the impairments of certain equity securities without readily determinable fair values recorded in the quarter ended March 31, 2020. In the event the Company has 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, are accounted for using the equity method and are included in "Long-term investments" in the accompanying combined balance sheet. At March 31, 2020 and December 31, 2019, the Company did not have any investments accounted for using the equity method.
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 the 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 8—Segment Information." Prior to January 1, 2020, ANGI's Handy business recorded revenue on a net basis. Effective January 1, 2020, the Company modified the Handy terms and conditions so that Handy, rather than the service professional, has the contractual relationship with the consumer to deliver the service and Handy, rather than the consumer, has the contractual relationship with the service professional. Consumers request services and pay for such services directly through the Handy platform and then Handy fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. This change in contractual terms requires gross revenue accounting treatment effective January 1, 2020. Also, in the case of certain tasks, HomeAdvisor provides a pre-priced product offering, pursuant to which consumers can request services through a HomeAdvisor platform and pay HomeAdvisor for the services directly. HomeAdvisor then fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. Revenue from HomeAdvisor’s pre-priced product offering is also recorded on a gross basis effective January 1, 2020. In addition to changing the presentation of revenue to gross from net, the timing of revenue recognition will change for pre-priced jobs and will be later than the timing of existing consumer connection revenue for HomeAdvisor because the Company will not be able to record revenue, generally, until the service professional completes the job on the Company's behalf. The change to gross revenue reporting for Handy and HomeAdvisor’s pre-priced product offering, effective January 1, 2020, resulted in an increase in revenue of $15.2 million during the three months ended March 31, 2020. Deferred Revenue Deferred revenue consists of advance payments that are received or are contractually due in advance of the Company's performance. 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 term of the applicable subscription period or expected completion of the Company's performance obligation is one year or less. The current and non-current deferred revenue balances at December 31, 2019 are $178.6 million and $1.3 million, respectively. During the three months ended March 31, 2020, the Company recognized $90.9 million of revenue that was included in the deferred revenue balance as of December 31, 2019. During the three months ended March 31, 2019, the Company recognized $76.0 million of revenue that was included in the deferred revenue balance as of December 31, 2018. The current and non-current deferred revenue balances at March 31, 2020 are $215.7 million and $1.3 million, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying combined 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 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 the Company has the right to invoice for services performed. For sales incentive programs where the customer relationship period is one year or less, the Company has elected the practical expedient to expense the costs as incurred.
Certain Risks and Concentrations - Services Agreement with Google	Certain Risks and Concentrations—Services Agreement with Google IAC and Google are party to a services agreement (the "Services Agreement"). If the Separation is consummated, IAC shall assign the Services Agreement to the Company. A meaningful portion of the Company's revenue 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.
Adoption of New Accounting Pronouncements	Adoption of New Accounting Pronouncements Adoption of ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The Company adopted ASU No. 2016-13 effective January 1, 2020. The standard significantly changes how entities measure credit losses for most financial assets, including accounts receivable. ASU No. 2016-13 replaces the “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. The Company adopted ASU No. 2016-13 using the modified retrospective approach and there was no cumulative effect arising from the adoption. The adoption of ASU No. 2016-13 did not have a material impact on the Company's combined financial statements. Adoption of ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes The Company adopted ASU No. 2019-12 effective January 1, 2020, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. Most amendments within ASU No. 2019-12 are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. The Company adopted ASU No. 2019-12 on January 1, 2020 using the modified retrospective basis for those amendments that are not applied on a prospective basis. The adoption of ASU No. 2019-12 did not have a material impact on the Company's combined financial statements.
