Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION ANGI Homeservices Inc. connects quality home service professionals across 500 different categories, from repairing and remodeling to cleaning and landscaping, with consumers. Over 240,000 domestic service professionals actively sought consumer matches, completed jobs or advertised work through ANGI Homeservices’ platforms and consumers turned to at least one of our brands to find a professional for approximately 32 million projects during the year ended December 31, 2020. The Company has established category-transforming products with brands such as HomeAdvisor, Angie’s List, and Handy. The HomeAdvisor digital marketplace service (“HomeAdvisor”) connects consumers with service professionals nationwide for home repair, maintenance and improvement projects. HomeAdvisor provides consumers with tools and resources to help them find local, pre-screened and customer-rated service professionals, as well as instantly book appointments online or connect them by telephone. Handy Technologies, Inc. (“Handy”), is a leading platform for connecting individuals looking for household services (primarily cleaning and handyman services) with top-quality, pre-screened independent service professionals. Together, the Company refers to the HomeAdvisor and Handy businesses in the United States as the “Marketplace”. The Company also owns and operates Angie’s List, which connects consumers with service professionals for local services through a nationwide online directory of service professionals in over 700 service categories, as well as provides consumers with valuable tools, services and content, including verified reviews of local service professionals, to help them research, shop and hire for local services. In addition to its market-leading U.S. operations, ANGI Homeservices owns leading home services online marketplaces in France (Travaux), Germany (MyHammer), Netherlands (Werkspot), United Kingdom (MyBuilder), Canada (HomeStars) and Italy (Instapro), as well as operations in Austria (MyHammer). The Company has two operating segments: (i) North America (United States and Canada), which includes HomeAdvisor, Angie’s List, Handy, HomeStars, and Felix, for periods prior to its sale on December 31, 2018, and (ii) Europe, which includes Travaux, MyHammer, MyBuilder, Werkspot and Instapro. As used herein, “ANGI Homeservices,” the “Company,” “ANGI,” “we,” “our” or “us” and similar terms refer to ANGI Homeservices Inc. and its subsidiaries (unless the context requires otherwise).

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Consolidation The Company prepares its consolidated financial statements in accordance with 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 among the Company and its subsidiaries have been eliminated. All intercompany transactions between (i) ANGI Homeservices and (ii) IAC and its subsidiaries, with the exception of a promissory note payable to a foreign subsidiary of IAC, are considered to be effectively settled for cash at the time the transaction is recorded. See “ Note 15—Related Party Transactions with IAC ” for additional information on transactions between ANGI Homeservices and IAC. In the opinion of management, the assumptions underlying the historical consolidated financial statements, including the basis on which the expenses have been allocated from IAC, are reasonable. However, the allocations may not reflect all of the expenses that ANGI Homeservices may have incurred as a standalone public company for the periods presented. COVID-19 Update The impact on the Company from the COVID-19 outbreak, which has been declared a “pandemic” by the World Health Organization, has been varied. 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, discretionary services (including those provided by certain of our service professionals) 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. When COVID-19 first impacted North America and Europe in the early spring of 2020, the Company experienced a decline in demand for service requests, driven primarily by decreases in demand in certain categories of jobs (particularly discretionary indoor projects). Toward the end of the spring of 2020, the Company experienced a rebound in service requests, exceeding pre-COVID-19 growth levels, driven by increased demand from homeowners who spent more time at home due to measures taken to reduce the spread of COVID-19. The Company continued to experience strong demand for home services in the last half of 2020. However, many service professionals’ businesses have been adversely impacted by labor and material constraints and many service professionals have limited capacity to take on new business, which has negatively impacted the Company's ability to monetize this increased level of service requests. In addition, North America, which represents 95% of the Company’s revenue for the year ended December 31, 2020, experienced a significant resurgence of the COVID-19 virus with record levels of infections being reported during the fourth quarter of 2020 and continuing into the first quarter of 2021. Europe, which is the second largest market for the Company’s products and services, has also seen a dramatic resurgence in COVID-19. This resurgence and the measures designed to curb its spread could materially and adversely affect our business, financial condition and results of operations. Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its consolidated 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 credit loss reserve; 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 capitalized software, leasehold improvements and equipment; the recoverability of goodwill and indefinite-lived intangible assets; 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. Revenue Recognition The Company adopted the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, effective January 1, 2018 using the modified retrospective transition method for open contracts as of the date of initial application. The effect of the adoption of ASU No. 2014-09 was that commissions paid to employees pursuant to certain sales incentive programs, which represent the incremental direct costs of obtaining a service professional contract, are now capitalized and amortized over the estimated life of a service professional (also referred to as the estimated customer relationship period). The cumulative effect of the adoption of ASU No. 2014-09 was the establishment of a current and non-current asset for capitalized sales commissions of $29.7 million and $4.2 million, respectively, and a related deferred tax liability of $8.3 million, resulting in a net increase to retained earnings of $25.6 million on January 1, 2018. The Company’s disaggregated revenue disclosures are presented in “ Note 12—Segment Information .” The Company accounts for a contract with a customer when it has approval and commitment from all parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to our customers and in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services or goods. Revenue is primarily derived from consumer connection revenue, which comprises fees paid by HomeAdvisor service professionals for consumer matches (regardless of whether the service professional ultimately provides the requested service) and revenue from completed jobs sourced through the HomeAdvisor and Handy platforms. Consumer connection revenue varies based upon several factors, including the service requested, product experience offered and geographic location of service. Consumer connection revenue is generally billed one week following a consumer match, with payment due upon receipt of invoice or collected when a consumer schedules a job through the HomeAdvisor and Handy platforms. The Company maintains revenue reserves for potential credits issued to HomeAdvisor services providers and for services provided by Handy service professionals to consumers. Revenue is also derived from (i) sales of time-based website, mobile and call center advertising to service professionals, (ii) HomeAdvisor service professional membership subscription fees, (iii) membership subscription fees from consumers and (iv) service warranty subscription and other services. Angie’s List service professionals generally pay for advertisements in advance on a monthly or annual basis at the option of the service professional, with the average advertising contract term being approximately one year. Angie’s List website, mobile and call center advertising revenue is recognized ratably over the contract term. Revenue from the sale of advertising in the Angie’s List Magazine is recognized in the period in which the publication is distributed. Service professional membership subscription revenue is initially deferred and is recognized using the straight-line method over the applicable subscription period, which is typically one year. Angie’s List prepaid consumer membership subscription fees are recognized as revenue using the straight-line method over the term of the applicable subscription period, which is typically one year. Prior to January 1, 2020, Handy 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. 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 $73.8 million during the year ended December 31, 2020. Transaction Price The objective of determining the transaction price is to estimate the amount of consideration the Company is due in exchange for its services or goods, including amounts that are variable. The Company determines the total transaction price, including an estimate of any variable consideration, at contract inception and reassesses this estimate each reporting period. The Company excludes from the measurement of transaction price all taxes assessed by governmental authorities that are both (i) imposed on and concurrent with a specific revenue-producing transaction and (ii) collected from customers. Accordingly, such tax amounts are not included as a component of net revenue or cost of revenue. For contracts that have an original duration of one year or less, the Company uses the practical expedient available under ASU No. 2014-09, applicable to such contracts and does not consider the time value of money. Arrangements with Multiple Performance Obligations The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers, which are directly observable or based on an estimate if not directly observable. Assets Recognized from the Costs to Obtain a Contract with a Customer The Company has determined that certain costs, primarily commissions paid to employees pursuant to certain sales incentive programs, meet the requirements to be capitalized as a cost of obtaining a contract. Capitalized sales commissions are amortized over the estimated customer relationship period. The Company calculates the estimated customer relationship period as the average customer life, which is based on historical data. When customer renewals are expected and the renewal commission is not commensurate with the initial commission, the average customer life includes renewal periods. 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. During the years ended December 31, 2020, 2019 and 2018 the Company recognized expense of $64.8 million, $56.8 million, and $50.0 million, respectively, related to the amortization of these costs. The current contract assets are $49.2 million and $35.1 million at December 31, 2020, and 2019, respectively. The non-current contract asset balances are $0.4 million and $4.0 million at December 31, 2020 and 2019, respectively. The current and non-current contract assets are included in “Other current assets” and “Other non-current assets,” respectively, in the accompanying consolidated balance sheet. Performance Obligations As permitted under the practical expedient available under ASU No. 2014-09, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is 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 we have the right to invoice for services performed. Accounts Receivables, Net of Credit Loss and Revenue Reserves Accounts receivable include amounts billed and currently due from customers. The credit loss reserve is based upon a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history and the specific customer’s ability to pay its obligation. The time between the Company’s issuance of an invoice and payment due date is not significant; customer payments that are not collected in advance of the transfer of promised services or goods are generally due no later than 30 days from invoice date. The Company also maintains reserves for potential credits issued to service professionals or other revenue adjustments. The amounts of these revenue reserves are based primarily upon historical experience. Credit Losses and Revenue Reserve The following table presents the changes in the credit loss reserve for the year ended December 31, 2020: December 31, 2020 (In thousands) Balance at January 1 $ 19,066 Current period provision for credit losses 78,229 Write-offs charged against the credit loss reserve (73,682) Recoveries collected 2,433 Balance at December 31 $ 26,046 The revenue reserve was $1.8 million and $1.2 million at December 31, 2020 and 2019, respectively. The total credit loss and revenue reserve was $27.8 million and $20.3 million as of December 31, 2020 and 2019. 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 its performance obligation is one year or less. During the years ended December 31, 2020 and 2019, the Company recognized $57.6 million and $61.0 million of revenue that was included in the deferred revenue balance as of December 31, 2019 and 2018, respectively. The current deferred revenue balances are $54.7 million and $58.2 million at December 31, 2020 and 2019, respectively. The non-current deferred revenue balances are $0.2 million and $0.2 million at December 31, 2020 and 2019, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying consolidated balance sheet. Cash and Cash Equivalents Cash and cash equivalents include cash and short-term investments, with maturities of less than 91 days from the date of purchase. Domestically, cash equivalents consist of AAA rated government money market funds, treasury discount notes, commercial paper, time deposits and certificates of deposit. Internationally, there are no cash equivalents at December 31, 2020 and 2019. Investments in Marketable Debt Securities The Company invests in marketable debt securities with active secondary or resale markets to ensure portfolio liquidity to fund current operations or satisfy other cash requirements as needed. Marketable debt securities are adjusted to fair value each quarter, and the unrealized gains and losses, net of tax, are included in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity. The specific-identification method is used to determine the cost of debt securities sold and the amount of unrealized gains and losses reclassified out of accumulated other comprehensive income (loss) into earnings. The Company reviews its debt securities for impairment, including from risk of credit loss, each reporting period. The Company recognizes an unrealized loss on debt securities in net earnings when the impairment is determined to be other-than- temporary. Factors the Company considers in making such determination include the duration, severity and reason for the decline in value and the potential recovery and our intent to sell the debt security. The Company also considers whether it will be required to sell the security before recovery of its amortized cost basis and whether the amortized cost basis cannot be recovered because of credit losses. If an impairment is considered to be other-than-temporary, the debt security will be written down to its fair value and the loss will be recognized within other income (expense), net. The Company held $50.0 million in marketable debt securities at December 31, 2020. The Company held no marketable debt securities at December 31, 2019. Capitalized Software, Leasehold Improvements and Equipment Capitalized software, leasehold improvements and equipment, including significant improvements, are recorded at cost. Repairs and maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, or, in the case of leasehold improvements, the lease term, if shorter. Asset Category Estimated Capitalized software and computer equipment 2 to 3 Years Furniture and other equipment 5 to 7 Years Leasehold improvements 5 to 25 Years The Company capitalizes certain internal use software costs including external direct costs utilized in developing or obtaining the software and compensation for personnel directly associated with the development of the software. Capitalization of such costs begins when the preliminary project stage is complete and ceases when the project is substantially complete and ready for its intended purpose. The net book value of capitalized internal use software was $67.9 million and $56.3 million at December 31, 2020 and 2019, respectively. Business Combinations The purchase price of each acquisition is attributed to the assets acquired and liabilities assumed based on their fair values at the date of acquisition, including identifiable intangible assets that either arise from a contractual or legal right or are separable from goodwill. The Company usually uses the assistance of outside valuation experts to assist in the allocation of purchase price to identifiable intangible assets acquired. While outside valuation experts may be used, management has ultimate responsibility for the valuation methods, models and inputs used and the resulting purchase price allocation. The excess purchase price over the net tangible and identifiable intangible assets is recorded as goodwill and is assigned to the reporting unit(s) that is expected to benefit from the combination as of the acquisition date. Goodwill and Indefinite-Lived Intangible Assets The Company assesses goodwill and indefinite-lived intangible assets for impairment annually as of October 1, or more frequently if an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit or the fair value of an indefinite-lived intangible asset has declined below its carrying value. At October 1, 2020, the Company has two reporting units: North America and Europe. When the Company elects to perform a qualitative assessment and concludes it is not more likely than not that the fair value of the reporting unit is less than its carrying value, no further assessment of that reporting unit’s goodwill is necessary; otherwise, a quantitative assessment is performed and the fair value of the reporting unit is determined. If the carrying value of the reporting unit exceeds its fair value an impairment equal to the excess is recorded. For the Company’s annual goodwill test at October 1, 2020, a qualitative assessment of the North America and Europe reporting units’ goodwill was performed and it was concluded that it was more likely than not that the fair value of these reporting units was in excess of their respective carrying values. In the aggregate, ANGI Homeservices’ October 1, 2020 market capitalization of $5.5 billion exceeded its carrying value by approximately $4.3 billion. The primary factor that the Company considered in its qualitative assessment for its Europe reporting unit were valuations performed during 2020 that indicated a fair value in excess of the carrying value. The fair value based on the valuation that was most proximate to, but not as of, October 1, 2020 exceeded the carrying value of the Europe reporting unit by $131.4 million. The primary factor that the Company considered in its qualitative assessment for its North America reporting unit was the significant excess of the estimated fair value of the North America reporting unit over its carrying value. The fair value of the North America reporting unit was estimated by subtracting the fair value of the Europe reporting unit, based on the valuation described above, from the October 1, 2020 market capitalization of the Company; the estimated fair value of the North America reporting unit exceeded its carrying value by approximately $4.1 billion. The fair value of the Company’s Europe reporting unit is determined using both an income approach based on discounted cash flows (“DCF”) and a market approach when it tests goodwill for impairment, either on an interim basis or annual basis as of October 1 each year. 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 are based on the Company’s most recent forecast and budget and, for years beyond the budget, the Company’s estimates, which are based, in part, on forecasted growth rates. The discount rates used in the DCF analyses are intended to reflect the risks inherent in the expected future cash flows of the respective reporting units. Assumptions used in the DCF analyses, including the discount rate, are assessed based on the reporting units’ current results and forecasted future performance, as well as macroeconomic and industry specific factors. The discount rate used in determining the fair value of the Company’s Europe reporting unit was 15% in both 2020 and 2019. 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 a reporting unit. To determine a peer group of companies for our respective reporting units, we considered companies relevant in terms of consumer use, monetization model, margin and growth characteristics, and brand strength operating in their respective sectors. While the Company has the option to qualitatively assess whether it is more likely than not that the fair values of its indefinite-lived intangible assets are less than their carrying values, the Company’s policy is to determine the fair value of each of its indefinite-lived intangible assets annually as of October 1, in part, because the level of effort required to perform the quantitative and qualitative assessments is essentially equivalent. 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 are 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 are based upon an estimate of the royalty rates that a market participant would pay to license the Company’s trade names and trademarks. Assumptions used in the avoided royalty DCF analyses, including the discount rate and royalty rate, are assessed annually based on the actual and projected cash flows related to the asset, as well as macroeconomic and industry specific factors. The discount rates used in the Company’s annual indefinite-lived impairment assessment ranged from 11.5% to 15.0% in 2020 and 11.5% to 27.5% in 2019, and the royalty rates used ranged from 2.0% to 5.5% in 2020 and 1.5% to 5.5% in 2019. The 2020, 2019 and 2018 annual assessments of goodwill and indefinite-lived intangible assets identified no impairments. Long-Lived Assets and Intangible Assets with Definite Lives Long-lived assets, which consist of ROU assets, capitalized software, leasehold improvements and equipment and intangible assets with definite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value is deemed not to be recoverable, an impairment loss is recorded equal to the amount by which the carrying value of the long-lived asset exceeds its fair value. Amortization of definite-lived intangible assets is computed either on a straight-line basis or based on the pattern in which the economic benefits of the asset will be realized. 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 Company’s non-financial assets, such as goodwill, intangible assets, ROU assets, capitalized software, leasehold improvements and equipment are adjusted to fair value only when an impairment is recognized. Such fair value measurements are based predominantly on Level 3 inputs. Warranty Costs As part of certain of our revenue arrangements, we include warranties providing customers with assurance on the quality of the services provided. Under our warranties, we incur costs to ensure the services performed are up to the customers standard and/or to reimburse for any claim for damages submitted in accordance with our warranty terms and conditions. These costs are recorded as a component of cost of revenue in the Consolidated Statement of Operations. Advertising Costs Advertising costs are expensed in the period incurred (when the advertisement first runs for production costs that are initially capitalized) and represent online marketing, including fees paid to search engines, offline marketing, which is primarily television advertising and partner-related payments to those who direct traffic to our platforms. Advertising expense was $487.6 million, $484.3 million and $334.7 million for the years ended December 31, 2020, 2019 and 2018, respectively. Legal Costs Legal costs are expensed as incurred. 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, the income tax provision and/or benefit has been computed for 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 consolidated statement of cash flows. The Company accounts for income taxes under the liability method, and deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying values of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided if it is determined that it is more likely than not that the deferred tax asset will not be realized. The Company records interest, net of any applicable related income tax benefit, on potential income tax contingencies as a component of income tax expense. The Company evaluates and accounts for uncertain tax positions using a two-step approach. Recognition (step one) occurs when the Company concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustainable upon examination. Measurement (step two) determines the amount of benefit that is greater than 50% likely to be realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. De-recognition of a tax position that was previously recognized would occur when the Company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. Earnings Per Share Basic earnings per share is computed by dividing net earnings attributable to ANGI Homeservices Inc. shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if stock appreciation rights, stock options and other commitments to issue common stock were exercised or equity awards vested resulting in the issuance of common

Income Tax Disclosure [Abstract]
INCOME TAXES	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, the income tax benefit and/or provision has been computed for 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 consolidated statement of cash flows. The tax sharing agreement between the Company and IAC governs the parties’ respective rights, responsibilities and obligations with respect to tax matters, including responsibility for taxes attributable to the Company, entitlement to refunds, allocation of tax attributes and other matters and, therefore, ultimately governs the amount payable to or receivable from IAC with respect to income taxes. Any differences between taxes currently payable or receivable from IAC under the tax sharing agreement and the current tax provision computed on an as if standalone, separate return basis for GAAP are reflected as adjustments to additional paid-in capital and as financing activities within the statement of cash flows. U.S. and foreign (loss) earnings before income taxes and noncontrolling interests are as follows: Years Ended December 31, 2020 2019 2018 (In thousands) U.S. $ (10,913) $ 39,821 $ 82,652 Foreign (8,415) (6,175) (12,628) Total $ (19,328) $ 33,646 $ 70,024 The components of the income tax (benefit) provision are as follows: Years Ended December 31, 2020 2019 2018 (In thousands) Current income tax provision: Federal $ (306) $ (43) $ — State 1,408 819 (20) Foreign (992) 806 905 Current income tax provision 110 1,582 885 Deferred income tax benefit Federal (5,163) (3,416) (5,549) State (6,249) 517 (1,100) Foreign (3,866) (351) (1,719) Deferred income tax benefit (15,278) (3,250) (8,368) Income tax benefit $ (15,168) $ (1,668) $ (7,483) The tax effects of cumulative temporary differences that give rise to significant deferred tax assets and deferred tax liabilities are presented below. The valuation allowance relates to deferred tax assets for which it is more likely than not that the tax benefit will not be realized.

At December 31, 2020, the Company has federal and state NOLs of $431.5 million and $375.9 million, respectively, available to offset future income. Of these federal NOLs, $59.3 million can be carried forward indefinitely and $372.2 million, if not utilized, will expire at various times between 2030 and 2037. The state NOLs, if not utilized, will expire at various times primarily between 2025 and 2040. Federal and state NOLs of $166.1 million and $79.9 million, respectively, can be used against future taxable income without restriction and the remaining NOLs will be subject to limitations under Section 382 of the Internal Revenue Code, separate return limitations, and applicable state law. At December 31, 2020, the Company has foreign NOLs of $413.7 million available to offset future income. Of these foreign NOLs, $374.3 million can be carried forward indefinitely and $39.4 million, if not utilized, will expire at various times between 2022 and 2039. During 2020, the Company recognized tax benefits related to NOLs of $12.6 million. At December 31, 2020, the Company has tax credit carryforwards of $16.6 million relating to federal and state tax credits for research activities. Of these credit carryforwards, $0.6 million can be carried forward indefinitely and $16.0 million, if not utilized, will expire between 2024 and 2040. The Company regularly assesses the realizability of deferred tax assets considering all available evidence including, to the extent applicable, the nature, frequency and severity of prior cumulative losses, forecasts of future taxable income, tax filing status, the duration of statutory carryforward periods, available tax planning and historical experience. At December 31, 2020, the Company has a U.S. gross deferred tax asset of $176.4 million that the Company expects to fully utilize on a more likely than not basis. During 2020, the Company’s valuation allowance increased by $5.6 million primarily due to an increase in foreign NOLs offset by a decrease in state NOLs. At December 31, 2020, the Company has a valuation allowance of $77.1 million related to the portion of NOLs and other items for which it is more likely than not that the tax benefit will not be realized. A reconciliation of the income tax benefit to the amounts computed by applying the statutory federal income tax rate to earnings before income taxes is shown as follows: Years Ended December 31, 2020 2019 2018 (In thousands) Income tax (benefit) provision at the federal statutory rate of 21% $ (4,058) $ 7,066 $ 14,705 State income taxes, net of effect of federal tax benefit 1,641 2,693 4,702 Deferred tax adjustment for enacted changes in tax law and rates (5,244) $ 502 $ (1,431) Change in judgement on beginning of the year valuation allowance (3,544) $ — $ — Stock-based compensation (2,914) (12,768) (25,184) Unbenefited losses 2,899 1,523 2,227 Research credit (2,494) (3,308) (1,169) Net adjustment related to the reconciliation of income tax provision accruals to tax returns (743) 448 (1,669) Other, net (711) 2,176 336 Income tax benefit $ (15,168) $ (1,668) $ (7,483) A reconciliation of the beginning and ending amount of unrecognized tax benefits, excluding interest, is as follows: December 31, 2020 2019 2018 (In thousands) Balance at January 1 $ 4,025 $ 2,356 $ 1,548 Additions based on tax positions related to the current year 1,676 1,325 411 Additions for tax positions of prior years 423 344 397 Settlements (856) — — Balance at December 31 $ 5,268 $ 4,025 $ 2,356 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 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. The IRS began its audit of the year ended December 31, 2017 in the second quarter of 2020. The statute of limitations for the years 2010 through 2012 and for the years 2013 through 2017 have been extended to May 31, 2021 and December 31, 2021, respectively. Returns filed in various other jurisdictions are open to examination for various 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 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 recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. At December 31, 2020, there are no accruals for interest and penalties. At December 31, 2019, accruals for interest are not material and there are no accruals for penalties. At December 31, 2020 and 2019, unrecognized tax benefits, including interest, are $5.3 million and $4.1 million respectively; all of which are for tax positions included in IAC’s consolidated tax return filings. If unrecognized tax benefits at December 31, 2020 are subsequently recognized, the income tax provision would be reduced by $5.1 million. The comparable amount as of December 31, 2019 is $4.0 million. The Company believes that it is reasonably possible that its unrecognized tax benefits could decrease by $0.5 million by December 31, 2021, due to settlements, all of which would reduce the income tax provision. At December 31, 2020, all of the Company’s international cash can be repatriated without any significant tax consequences.

Business Combinations [Abstract]
BUSINESS COMBINATIONS	BUSINESS COMBINATIONS Handy Acquisition On October 19, 2018, the Company acquired 100% of Handy, a leading platform for connecting individuals looking for household services, for total consideration of $168.4 million. This includes the aggregate fair value of 8.6 million shares of Class A common stock issued by the Company of $165.8 million, which was based on the closing stock price of ANGI on the NASDAQ on October 19, 2018 of $19.31 and cash consideration paid by the Company. During 2019, the Company finalized its assessment of net operating losses acquired in the Handy acquisition. As a result, the Company revised the purchase price allocation for Handy by increasing the fair value of deferred tax assets by $27.2 million and decreasing goodwill by $27.2 million. The financial results of Handy are included in the Company’s consolidated financial statements, within the North America segment, beginning October 19, 2018. The table below summarizes the fair values of the assets acquired and liabilities assumed at the date of acquisition: Handy (In thousands) Cash and cash equivalents $ 5,710 Other current assets 2,050 Goodwill 115,183 Intangible assets 38,800 Other non-current assets 8 Deferred income taxes 20,070 Total assets 181,821 Current liabilities (13,419) Net assets acquired $ 168,402 The purchase price was based on the expected financial performance of Handy, 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 because Handy is complementary and synergistic to the other North America businesses of ANGI Homeservices. The fair values of the identifiable intangible assets acquired at the date of acquisition are as follows: Handy (In thousands) Weighted-Average Indefinite-lived trade name and trademarks $ 18,800 Indefinite Developed technology 15,600 4 User base 3,400 1 Retail partners 600 3 Service professionals 400 1 Total identifiable intangible assets acquired $ 38,800 Other current assets, other non-current assets and current liabilities of Handy 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 variations of the income approach; specifically, in respective order, the relief from royalty and excess earnings methodologies. The fair values of user base, retail partners, and service professionals were determined using a cost approach that utilized the cost to replace 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.

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 below, plus accrued and unpaid interest thereon, if any, to the applicable redemption date, if redeemed during the twelve-month period beginning on August 15 of the years indicated below: Year Percentage 2023 101.938 % 2024 100.969 % 2025 and thereafter 100.000 % The indenture governing the 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 December 31, 2020, there were no limitations pursuant thereto. ANGI Group Term Loan and ANGI Group Revolving Facility ANGI was a party to a credit agreement that terminates on November 5, 2021. The credit agreement governs the Term Loan and revolving credit facility (the “Revolving Facility”). On August 12, 2020, ANGI Group entered into a joinder agreement with the Company, the other subsidiaries of the Company that are party to the credit agreement, and each of the other loan parties to the credit agreement, pursuant to which ANGI Group became the successor borrower under the credit agreement (“ANGI Group Credit Agreement”) and ANGI Homeservices Inc.’s obligations thereunder were terminated. In addition, on August 12, 2020, the definition of “Permitted Unsecured Ratio Debt” in the credit agreement was amended to remove the requirement that guarantees of certain indebtedness of the borrower be subordinated to the guarantees under the credit agreement. The outstanding balance of the ANGI Group Term Loan was $220 million and $247.5 million at December 31, 2020 and 2019, respectively. As of December 31, 2020, the Company prepaid its quarterly principal payments totaling of $13.8 million due in 2021. There are quarterly principal payments of $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 December 31, 2020 and 2019, the Term Loan bore interest at LIBOR plus 2.00% and LIBOR plus 1.50% respectively. The spread over LIBOR is subject to change in future periods based on ANGI Group’s consolidated net leverage ratio. The interest rate was 2.16% and 3.25%, at December 31, 2020 and 2019, respectively. The ANGI Group Credit Agreement requires ANGI Group 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. The ANGI Group Credit Agreement also contains covenants that would limit ANGI Group’s ability to pay dividends or make distributions in the event a default has occurred or ANGI Group’s consolidated net leverage ratio exceeds 4.25 to 1.0. At December 31, 2020, there were no limitations pursuant thereto. The $250.0 million ANGI Group Revolving Facility expires on November 5, 2023. At December 31, 2020 and 2019, there were no outstanding borrowings under the ANGI Group Revolving Facility. The annual commitment fee on undrawn funds is based on ANGI Group’s consolidated net leverage ratio most recently reported and was 35 basis points and 25 basis points at December 31, 2020 and 2019, respectively. Any future borrowings under the ANGI Group Revolving Facility would bear interest, at ANGI Group’s option, at either a base rate or LIBOR, in each case plus an applicable margin, which is based on ANGI Group’s consolidated net leverage ratio. The financial and other covenants are the same as those for the ANGI Group Term Loan. The ANGI Group Senior Notes and ANGI Group Credit Agreement are guaranteed by certain of ANGI Group’s wholly-owned material domestic subsidiaries and ANGI Group’s obligations under the ANGI Group Credit Agreement are secured by substantially all assets of ANGI Group and the guarantors, subject to certain exceptions. The ANGI Group Term Loan and outstanding borrowings, if any, under the ANGI Group Revolving Facility rank equally with each other, and have priority over the ANGI Group Senior Notes to the extent of the value of the assets securing the borrowings under the ANGI Group Credit Agreement.

Accordingly, the weighted average basic shares outstanding were used to compute all earnings per share amounts. (b) If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of stock appreciation rights, stock options and subsidiary denominated equity and vesting of restricted stock units (“RSUs”). For the years ended December 31, 2019 and 2018, 5.5 million, and 3.1 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. (c) Market-based awards and performance-based stock units are considered contingently issuable shares. Shares issuable upon exercise or vesting of market-based awards and performance-based stock units are included in the denominator for earnings per share if (i) the applicable performance or market condition(s) has been met and (ii) the inclusion of the market-based award and performance-based stock units is dilutive for the respective reporting periods. For the years ended December 31, 2019 and 2018, 0.9 million, and 1.3 million shares underlying market-based awards and performance-based stock units, respectively, were excluded from the calculation of diluted earnings per share because the performance or market condition(s) had not been met.

STOCK-BASED COMPENSATION

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATIONThe Company currently has one active stock plan, which became effective in 2017 upon the completion of the combination of IAC’s HomeAdvisor business and Angie’s List, Inc. on September 29, 2017 (the “Combination”). The 2017 plan covers stock options, stock appreciation rights and RSU awards, including those that are linked to the achievement of the Company’s stock price, known as market-based awards (“MSUs”) and those that are linked to the achievement of a performance target, known as performance-based awards (“PSUs”), denominated in shares of ANGI Homeservices common stock, as well as provides for the future grant of these and other equity awards. The 2017 plan authorizes the Company to grant awards to its employees, officers, directors and consultants. At December 31, 2020, there are 15.2 million shares available for grant under the 2017 plan. The 2017 plan has a stated term of ten years, and provides that the exercise price of stock options and stock appreciation rights granted will not be less than the market price of the Company’s common stock on the grant date. The plan does not specify grant dates or vesting schedules for awards, as those determinations have been delegated to the Compensation Committee of ANGI Homeservices Board of Directors (the “Committee”). Each grant agreement reflects the grant date and vesting schedule for that particular grant as determined by the Committee. Stock options and stock appreciation rights granted subsequent to the Combination through December 31, 2018 generally vest in equal annual installments over a four-year period from the grant date. RSU awards granted subsequent to the Combination through December 31, 2020 generally vest either in two 50% installments over a three two Stock-based compensation expense recognized in the consolidated statement of operations includes expense related to: (i) the Company’s stock options, stock appreciation rights and RSUs; (ii) equity instruments denominated in shares of its subsidiaries; and (iii) IAC denominated stock options and PSUs held by ANGI Homeservices employees. The amount of stock-based compensation expense recognized is net of estimated forfeitures. The forfeiture rate is estimated at the grant date based on historical experience and revised, if necessary, in subsequent periods if actual forfeitures differ from the estimated rate. The expense ultimately recorded is for the awards that vest. At December 31, 2020, there was $77.2 million of unrecognized compensation cost, net of estimated forfeitures, related to all equity-based awards, which is expected to be recognized over a weighted average period of approximately 2.2 years. The total income tax benefit recognized in the accompanying consolidated statement of operations for the years ended December 31, 2020, 2019 and 2018 related to all stock-based compensation is $24.3 million, $28.8 million and $49.5 million, respectively. The aggregate income tax benefit recognized related to the exercise of stock options and stock appreciation rights for the years ended December 31, 2020, 2019 and 2018 is $11.4 million, $27.9 million and $40.2 million, respectively. There may be some delay in the timing of the realization of the cash benefit of the income tax deductions related to stock-based compensation because it will be dependent upon the amount and timing of future taxable income and the timing of estimated income tax payments. Stock Options and Stock Appreciation Rights Stock options and stock appreciation rights outstanding at December 31, 2020 and changes during the year ended December 31, 2020 were as follows: December 31, 2020 Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (In Years) Aggregate Intrinsic Value (Shares and intrinsic value in thousands) Outstanding at January 1, 2020 23,984 $ 3.89 Granted — — Exercised (12,931) 3.18 Forfeited (352) 6.16 Expired (12) 15.03 Outstanding at December 31, 2020 10,689 $ 4.67 5.68 $ 92.08 Exercisable 8,944 $ 4.59 5.59 $ 77.97 The aggregate intrinsic value in the table above represents the difference between ANGI Homeservices closing stock price on the last trading day of 2020 and the exercise price, multiplied by the number of in-the-money awards that would have been exercised had all award holders exercised their awards on December 31, 2020. The total intrinsic value of awards exercised during the years ended December 31, 2020, 2019 and 2018 is $120.9 million, $107.5 million and $151.2 million, respectively. The following table summarizes the information about stock options and stock appreciation rights outstanding and exercisable at December 31, 2020: Awards Outstanding Awards Exercisable Range of Exercise Prices Outstanding Weighted average Weighted Exercisable Weighted average Weighted (Shares in thousands) $0.01 to $3.00 2,864 4.9 $ 2.29 2,864 4.9 $ 2.29 $3.01 to $6.00 6,814 6.1 4.53 5,213 6.1 4.53 $6.01 to $9.00 106 4.0 8.04 106 4 8.04 $9.01 to $12.00 405 6.0 10.54 324 5.7 10.47 $12.01 to $15.00 369 5.5 12.94 306 5.3 12.98 $15.01 to $18.00 — — — — — — $18.01 to$21.00 115 2.2 19.88 115 2.2 19.88 $21.01 to $24.00 16 2.6 22.02 16 2.6 22.02 10,689 5.7 $ 4.67 8,944 5.6 $ 4.59 There were no stock options or stock appreciation rights granted by the Company for the years ended December 31, 2020, 2019 or 2018. In connection with the Combination, the previously issued HomeAdvisor (US) stock appreciation rights were converted into ANGI Homeservices’ equity awards resulting in a modification charge. Included in stock-based compensation expense in the years ended December 31, 2020, 2019 and 2018 were charges of $21.1 million, $29.0 million and $56.9 million, respectively, related to these modified awards, and the remaining charge of $0.9 million will be recognized over the remaining vesting period of the modified awards. In connection with the departure of the president and chief operating officer in the fourth quarter of 2020, the Company recognized a modification charge of $6.8 million related to the acceleration of vesting of his unvested stock appreciation rights and the extension of the post-termination exercise period for his vested and exercisable stock appreciation rights. In connection with the chief executive officer transition during the fourth quarter of 2018, the Company accelerated $3.9 million of expense into 2018 from 2019. No cash was received from stock option exercises during the year ended December 31, 2020 because they were net settled in shares of ANGI Homeservices’ common stock. Cash received from stock option exercises was $0.6 million and $4.7 million for the years ended December 31, 2019 and 2018, respectively. The Company currently settles all equity awards on a net basis. In connection with the Combination, previously issued stock appreciation rights related to the common stock of HomeAdvisor (US) were converted into ANGI stock appreciation rights that are settleable, at the Company’s option, on a net basis with the Company remitting withholding taxes on behalf of the employee or on a gross basis with the Company issuing a sufficient number of Class A shares to cover the withholding taxes. In addition, at IAC’s option, these awards can be settled in either Class A shares of ANGI or shares of IAC common stock. If settled in IAC common stock, ANGI reimburses IAC in either cash or through the issuance of Class A shares to IAC. Assuming all of the stock appreciation rights outstanding on December 31, 2020 were net settled on that date, ANGI would have issued 3.4 million Class A shares (either to award holders or to IAC as reimbursement) and ANGI would have remitted $45.2 million in cash for withholding taxes (assuming a 50% withholding rate). Assuming all other ANGI equity awards outstanding on December 31, 2020, were net settled on that date, including stock options, RSUs and subsidiary denominated equity described below, ANGI would have issued 6.0 million shares and would have remitted $76.8 million in cash for withholding taxes (assuming a 50% withholding rate). Restricted Stock Units, Market-based Stock Units and Performance-based Stock Units RSUs, MSUs and PSUs are awards in the form of phantom shares or units denominated in a hypothetical equivalent number of shares of ANGI Homeservices common stock and with the value of each RSU and PSU equal to the fair value of ANGI Homeservices common stock at the date of grant. The value of each MSU is estimated using a lattice model that incorporates a Monte Carlo simulation of ANGI’s stock price. Each RSU, MSU and PSU grant is subject to service-based vesting, where a specific period of continued employment must pass before an award vests. MSUs also include market-based vesting, tied to the stock price of ANGI before an award vests and PSUs include performance-based vesting, where certain performance targets set at the time of grant must be achieved before an award vests. For RSU grants, the expense is measured at the grant date as the fair value of ANGI Homeservices common stock and expensed as stock-based compensation over the vesting term. For MSU grants, the expense is measured using a lattice model and expensed as stock-based compensation over the requisite service period. For PSU grants, the expense is measured at the grant date as the fair value of ANGI Homeservices common stock and expensed as stock-based compensation over the vesting term if the performance targets are considered probable of being achieved. Unvested RSUs, MSUs and PSUs outstanding at December 31, 2020 and changes during the year ended December 31, 2020 are as follows: RSUs MSUs PSUs Number of Shares Weighted Average Number of Shares (a) Weighted Average Number of Shares (a) Weighted Average (Shares in thousands) Unvested at January 1, 2020 5,660 $ 15.29 3,503 $ 3.62 881 $ 15.89 Granted 6,962 7.37 — — 1,844 6.92 Vested (2,128) 13.78 (738) 6.8 — — Forfeited (934) 11.93 (269) 6.8 (767) 16.4 Unvested at December 31, 2020 9,560 $ 10.19 2,496 $ 7.82 1,958 $ 5.11 ___________________________ (a) Included in the table are MSUs and PSUs which vests in varying amounts depending upon certain market or performance conditions. The MSUs and PSUs in the table above includes these awards at their maximum potential payout. In 2019, the Company granted certain MSUs that are liability-classified stock-settled awards with a market condition. The fair value of these awards is subject to remeasurement each reporting period until settlement of the award. The total expense related to these awards will ultimately be equal to the number of shares vested based on the fair value of ANGI Homeservices’ common stock on the settlement date. The weighted average fair value of RSUs granted during the years ended December 31, 2020, 2019 and 2018 based on market prices of ANGI Homeservices’ common stock on the grant date was $7.37, $13.16 and $18.08, respectively. There were no MSUs granted during the year ended December 31, 2020. The weighted average fair value of MSUs granted during the year ended December 31, 2019 based on the lattice model was $3.67. The weighted average fair value of PSUs granted during the years ended December 31, 2020 and 2019 based on market prices of ANGI Homeservices’ common stock on the grant date was $6.92 and $15.93, respectively. There were no MSUs or PSUs granted or outstanding during the year ended December 31, 2018. The total fair value of RSUs that vested during the years ended December 31, 2020, 2019 and 2018 was $23.4 million, $16.1 million and $19.5 million, respectively. The total fair value of MSUs that vested during the years ended December 31, 2020 and 2019, was $5.2 million and $3.2 million, respectively. There were no PSUs that vested during the years ended December 31, 2020, 2019 and 2018. In connection with the departure of the president and chief operating officer in the fourth quarter of 2020, the Company recognized a modification charge of $7.3 million related to the acceleration of vesting of his unvested RSUs. Equity Instruments Denominated in the Shares of Certain Subsidiaries ANGI Homeservices has granted stock appreciation rights denominated in the equity of certain non-publicly traded subsidiaries to employees and management of those subsidiaries. These equity awards vest over a period of years, which is typically four years. The value of the stock appreciation rights is tied to the value of the common stock of these subsidiaries, which is determined by the Company using a variety of valuation techniques including a combination of market based and discounted cash flow valuation methodologies. Accordingly, these interests only have value to the extent the relevant business appreciates in value above the initial value utilized to determine the exercise price. These interests can have significant value in the event of significant appreciation. The fair value of these interests is generally determined by negotiation or arbitration when settled, which will occur at various dates through 2026 and are ultimately settled in IAC common stock or ANGI Homeservices Class A common stock, at IAC’s election. These equity awards are settled on a net basis, with the award holder entitled to receive a payment in shares equal to the intrinsic value of the award at exercise less an amount equal to the required cash tax withholding payment. The expense associated with these equity awards is initially measured at fair value, using the Black-Scholes option pricing model, at the grant date and is expensed as stock-based compensation over the vesting term. The plans under which these awards are granted establish specific settlement dates or liquidity events for which the valuation of the relevant subsidiary is determined for purposes of settlement of the awards.

The Company believes this measure is useful for analysts and investors as this measure allows a more meaningful comparison between our performance and that of our competitors. The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature. Adjusted EBITDA has certain limitations because it excludes the impact of these expenses.

Leases [Abstract]
LEASES	LEASES The Company leases office space, data center facilities and equipment in connection with its operations under various operating leases, the majority of which contain escalation clauses. ROU assets represent the Company’s right to use the underlying assets for the lease term and lease liabilities represent the present value of the Company’s obligation to make payments arising from these leases. ROU assets and related lease liabilities are based on the present value of fixed lease payments over the lease term using the Company’s incremental borrowing rate on the lease commencement date or January 1, 2019 for leases that commenced prior to that date. The Company combines the lease and non-lease components of lease payments in determining ROU assets and related lease liabilities. If the lease includes one or more options to extend the term of the lease, the renewal option is considered in the lease term if it is reasonably certain the Company will exercise the option(s). Lease expense is recognized on a straight-line basis over the term of the lease. As permitted by ASC 842, leases with an initial term of twelve months or less (“short-term leases”) are not recorded on the accompanying consolidated balance sheet. Variable lease payments consist primarily of common area maintenance, utilities and taxes, which are not included in the recognition of ROU assets and related lease liabilities. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Commitments The Company has entered into certain off-balance sheet commitments that require the future purchase of services (“purchase obligations”). Future payments under non-cancelable unconditional purchase obligations as of December 31, 2020 are as follows: Amount of Commitment Expiration Per Period Less Than 1–3 3–5 More Than Total (In thousands) Purchase obligations $ 12,916 $ 22 $ — $ — $ 12,938 Purchase obligations include (i) a remaining minimum payment of $5.6 million that is due in 2021 under the Company’s allocable share of a three-year cloud computing arrangement, and (ii) payments of $7.3 million related to advertising commitments to be made in 2021. The Company has an allocable share of a three-year cloud computing arrangement between IAC and a third party provider of $15.6 million, of which $3.2 million and $5.6 million was paid in 2020 and 2019, respectively, and the Company had a related prepaid asset of $4.2 million and $4.3 million at December 31, 2020 and 2019, respectively, which is included in “Other current assets” on the consolidated balance sheet. 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 we believe an unfavorable outcome is not probable and, therefore, no reserve is established. Although management currently believes that resolving claims against us, 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.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS WITH IAC	RELATED PARTY TRANSACTIONS WITH IAC Relationship with IAC ANGI Homeservices and IAC have entered into certain agreements to govern their relationship. These agreements include: a contribution agreement; an investor rights agreement; a services agreement; a tax sharing agreement; and an employee matters agreement. On October 10, 2018, ANGI issued 5.1 million shares of its Class B common stock to IAC pursuant to the post-closing adjustment provision of the Angie's List merger agreement. Contribution Agreement The contribution agreement sets forth the agreements between the Company and IAC regarding the principal transactions necessary for IAC to separate the HomeAdvisor business from IAC's other businesses and to cause the HomeAdvisor business to be transferred to ANGI Homeservices prior to the Combination, as well as governs certain aspects of our relationship following the Combination. Under the contribution agreement, the Company agreed to assume all of the assets and liabilities related to the HomeAdvisor business and agreed to indemnify IAC against any losses arising out of any breach by the Company of the contribution agreement or the other transaction related agreements described below. IAC also agreed to indemnify the Company against losses arising out of any breach by IAC of the contribution agreement or any of the other transaction related agreements described below. Investor Rights Agreement The investor rights agreement provides IAC with certain registration, preemptive and governance rights related to the Company and the shares of its capital stock it holds, as well as certain governance rights for the benefit of stockholders other than IAC. Services Agreement The services agreement governs services that IAC provides to the Company including, among others: (i) assistance with certain legal, M&A, human resources, finance, risk management, internal audit and treasury functions, health and welfare benefits, information security services and insurance and tax affairs, including assistance with certain public company and unclaimed property reporting obligations; (ii) accounting, controllership and payroll processing services; (iii) investor relations services; (iv) tax compliance services; and (v) such other services as to which IAC and the Company may agree. The services agreement automatically renews annually for an additional one-year period for so long as IAC continues to own a majority of the outstanding shares of the Company’s common stock. For the years ended December 31, 2020, 2019 and 2018, the Company was charged $4.8 million, $4.8 million and $5.7 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 December 31, 2020 and 2019, respectively. At December 31, 2018, the Company had an outstanding receivable due from IAC of $0.1 million pursuant to the services agreement. This amount was deducted from the charges due to IAC pursuant to the services agreement discussed above during the first quarter of 2019. Separately, the Company subleases office space to IAC and charged rent of $1.8 million and $1.4 million for the years ended December 31, 2020 and 2019, respectively. There were no amounts charged pursuant to subleases for office space to IAC for the year ended December 31, 2018. At both December 31, 2020 and 2019, there were outstanding receivables of less than $0.1 million due from IAC pursuant to sublease agreements, which were subsequently paid in full in the first quarter of 2021 and 2020, respectively. Tax Sharing Agreement The tax sharing agreement governs the rights, responsibilities, and obligations of the Company and IAC with respect to tax liabilities and benefits, entitlements to refunds, preparation of tax returns, tax contests and other tax matters regarding U.S. federal, state, local and foreign income taxes. Under the tax sharing agreement, the Company is generally responsible and required to indemnify IAC for: (i) all taxes imposed with respect to any consolidated, combined or unitary tax return of IAC or its subsidiaries that includes the Company or any of its subsidiaries to the extent attributable to the Company or any of its subsidiaries, as determined under the tax sharing agreement, and (ii) all taxes imposed with respect to any of the Company's or its subsidiaries’ consolidated, combined, unitary or separate tax returns. At December 31, 2020 and 2019, the Company had outstanding payables of $0.9 million and $0.2 million, respectively, due to IAC pursuant to the tax sharing agreement, which is included in “Accrued expenses and other current liabilities” in the accompanying consolidated balance sheet. There were $3.1 million of refunds received from IAC pursuant to this agreement during the twelve months ended December 31, 2020. During the first quarter of 2019, $11.4 million was paid to IAC, pursuant to this agreement. Employee Matters Agreement The employee matters agreement addresses certain compensation (including stock-based compensation) and benefit issues related to the allocation of liabilities associated with: (i) employment or termination of employment, (ii) employee benefit plans and (iii) equity awards. Under the employee matters agreement, the Company's employees participate in IAC’s U.S. health and welfare plans, 401(k) plan and flexible benefits plan and the Company reimburses IAC for the costs of such participation. In the event IAC no longer retains shares representing at least 80% of the aggregate voting power of shares entitled to vote in the election of the Company’s Board of Directors, ANGI Homeservices will no longer participate in IAC’s employee benefit plans, but will establish its own employee benefit plans that will be substantially similar to the plans sponsored by IAC prior to the Combination. In addition, the employee matters agreement requires the Company to reimburse IAC for the cost of any IAC equity awards held by ANGI Homeservices current and former employees, with IAC electing to receive payment in cash or shares of our Class B common stock. This agreement also provides that IAC may require stock appreciation rights granted prior to the closing of the Combination and equity awards in our subsidiaries to be settled in either shares of our Class A common stock or IAC common stock. To the extent shares of IAC common stock are issued in settlement of these awards, the Company is obligated to reimburse IAC for the cost of those shares by issuing shares of our Class A common stock in the case of stock appreciation rights granted prior to the closing of the Combination and shares of our Class B common stock in the case of equity awards in our subsidiaries. Lastly, pursuant to the employee matters agreement, in the event of a distribution of ANGI capital stock to IAC stockholders in a transaction intended to qualify as tax-free for U.S. federal income tax purposes, the Compensation Committee of the IAC Board of Directors has the exclusive authority to determine the treatment of outstanding IAC equity awards. Such authority includes (but is not limited to) the ability to convert all or part of IAC equity awards outstanding immediately prior to the distribution into equity awards denominated in shares of ANGI Class A Common Stock, which ANGI would be obligated to assume and which would be dilutive to ANGI's stockholders. For the years ended December 31, 2020, 2019 and 2018, 0.3 million, 0.5 million and 0.9 million shares of ANGI Homeservices Class B common stock were issued to IAC, respectively, 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 Homeservices employees.

BENEFIT PLANS	BENEFIT PLANSThe Company’s employees in the United States are eligible to participate in a retirement savings program offered by IAC, which is qualified under Section 401(k) of the Internal Revenue Code. Under the IAC/InterActiveCorp Retirement Savings Plan (the “IAC Plan”), participating employees may contribute up to 50% of their pre-tax earnings, but not more than statutory limits. The current employer match under the IAC Plan is fifty cents for each dollar a participant contributes in the IAC Plan, with a maximum contribution of 3% of a participant’s eligible earnings. Matching contributions under the IAC Plan for the years ended December 31, 2020, 2019 and 2018 were $7.7 million, $6.3 million and $5.6 million, respectively. Matching contributions are invested in the same manner as each participant’s voluntary contributions in the investment options provided under the IAC Plan. An investment option in the IAC Plan is IAC common stock, but neither participant nor matching contributions are required to be invested in IAC common stock.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2020
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The Company prepares its consolidated financial statements in accordance with 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 among the Company and its subsidiaries have been eliminated. All intercompany transactions between (i) ANGI Homeservices and (ii) IAC and its subsidiaries, with the exception of a promissory note payable to a foreign subsidiary of IAC, are considered to be effectively settled for cash at the time the transaction is recorded. See “ Note 15—Related Party Transactions with IAC ” for additional information on transactions between ANGI Homeservices and IAC. In the opinion of management, the assumptions underlying the historical consolidated financial statements, including the basis on which the expenses have been allocated from IAC, are reasonable. However, the allocations may not reflect all of the expenses that ANGI Homeservices may have incurred as a standalone public company for the periods presented.
Accounting Estimates	Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its consolidated 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 credit loss reserve; 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 capitalized software, leasehold improvements and equipment; the recoverability of goodwill and indefinite-lived intangible assets; 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.
Revenue Recognition	Revenue Recognition The Company adopted the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, effective January 1, 2018 using the modified retrospective transition method for open contracts as of the date of initial application. The effect of the adoption of ASU No. 2014-09 was that commissions paid to employees pursuant to certain sales incentive programs, which represent the incremental direct costs of obtaining a service professional contract, are now capitalized and amortized over the estimated life of a service professional (also referred to as the estimated customer relationship period). The cumulative effect of the adoption of ASU No. 2014-09 was the establishment of a current and non-current asset for capitalized sales commissions of $29.7 million and $4.2 million, respectively, and a related deferred tax liability of $8.3 million, resulting in a net increase to retained earnings of $25.6 million on January 1, 2018. The Company’s disaggregated revenue disclosures are presented in “ Note 12—Segment Information .” The Company accounts for a contract with a customer when it has approval and commitment from all parties, the rights of the parties and payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Revenue is recognized when control of the promised services or goods is transferred to our customers and in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services or goods. Revenue is primarily derived from consumer connection revenue, which comprises fees paid by HomeAdvisor service professionals for consumer matches (regardless of whether the service professional ultimately provides the requested service) and revenue from completed jobs sourced through the HomeAdvisor and Handy platforms. Consumer connection revenue varies based upon several factors, including the service requested, product experience offered and geographic location of service. Consumer connection revenue is generally billed one week following a consumer match, with payment due upon receipt of invoice or collected when a consumer schedules a job through the HomeAdvisor and Handy platforms. The Company maintains revenue reserves for potential credits issued to HomeAdvisor services providers and for services provided by Handy service professionals to consumers. Revenue is also derived from (i) sales of time-based website, mobile and call center advertising to service professionals, (ii) HomeAdvisor service professional membership subscription fees, (iii) membership subscription fees from consumers and (iv) service warranty subscription and other services. Angie’s List service professionals generally pay for advertisements in advance on a monthly or annual basis at the option of the service professional, with the average advertising contract term being approximately one year. Angie’s List website, mobile and call center advertising revenue is recognized ratably over the contract term. Revenue from the sale of advertising in the Angie’s List Magazine is recognized in the period in which the publication is distributed. Service professional membership subscription revenue is initially deferred and is recognized using the straight-line method over the applicable subscription period, which is typically one year. Angie’s List prepaid consumer membership subscription fees are recognized as revenue using the straight-line method over the term of the applicable subscription period, which is typically one year. Prior to January 1, 2020, Handy 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. 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 $73.8 million during the year ended December 31, 2020. Transaction Price The objective of determining the transaction price is to estimate the amount of consideration the Company is due in exchange for its services or goods, including amounts that are variable. The Company determines the total transaction price, including an estimate of any variable consideration, at contract inception and reassesses this estimate each reporting period. The Company excludes from the measurement of transaction price all taxes assessed by governmental authorities that are both (i) imposed on and concurrent with a specific revenue-producing transaction and (ii) collected from customers. Accordingly, such tax amounts are not included as a component of net revenue or cost of revenue. For contracts that have an original duration of one year or less, the Company uses the practical expedient available under ASU No. 2014-09, applicable to such contracts and does not consider the time value of money. Arrangements with Multiple Performance Obligations The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines standalone selling prices based on the prices charged to customers, which are directly observable or based on an estimate if not directly observable. Assets Recognized from the Costs to Obtain a Contract with a Customer The Company has determined that certain costs, primarily commissions paid to employees pursuant to certain sales incentive programs, meet the requirements to be capitalized as a cost of obtaining a contract. Capitalized sales commissions are amortized over the estimated customer relationship period. The Company calculates the estimated customer relationship period as the average customer life, which is based on historical data. When customer renewals are expected and the renewal commission is not commensurate with the initial commission, the average customer life includes renewal periods. 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. During the years ended December 31, 2020, 2019 and 2018 the Company recognized expense of $64.8 million, $56.8 million, and $50.0 million, respectively, related to the amortization of these costs. The current contract assets are $49.2 million and $35.1 million at December 31, 2020, and 2019, respectively. The non-current contract asset balances are $0.4 million and $4.0 million at December 31, 2020 and 2019, respectively. The current and non-current contract assets are included in “Other current assets” and “Other non-current assets,” respectively, in the accompanying consolidated balance sheet. Performance Obligations As permitted under the practical expedient available under ASU No. 2014-09, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is 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 we have the right to invoice for services performed. Accounts Receivables, Net of Credit Loss and Revenue Reserves Accounts receivable include amounts billed and currently due from customers. The credit loss reserve is based upon a number of factors, including the length of time accounts receivable are past due, the Company’s previous loss history and the specific customer’s ability to pay its obligation. The time between the Company’s issuance of an invoice and payment due date is not significant; customer payments that are not collected in advance of the transfer of promised services or goods are generally due no later than 30 days from invoice date. The Company also maintains reserves for potential credits issued to service professionals or other revenue adjustments. The amounts of these revenue reserves are based primarily upon historical experience. Credit Losses and Revenue Reserve The following table presents the changes in the credit loss reserve for the year ended December 31, 2020: December 31, 2020 (In thousands) Balance at January 1 $ 19,066 Current period provision for credit losses 78,229 Write-offs charged against the credit loss reserve (73,682) Recoveries collected 2,433 Balance at December 31 $ 26,046 The revenue reserve was $1.8 million and $1.2 million at December 31, 2020 and 2019, respectively. The total credit loss and revenue reserve was $27.8 million and $20.3 million as of December 31, 2020 and 2019. 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 its performance obligation is one year or less. During the years ended December 31, 2020 and 2019, the Company recognized $57.6 million and $61.0 million of revenue that was included in the deferred revenue balance as of December 31, 2019 and 2018, respectively. The current deferred revenue balances are $54.7 million and $58.2 million at December 31, 2020 and 2019, respectively. The non-current deferred revenue balances are $0.2 million and $0.2 million at December 31, 2020 and 2019, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying consolidated balance sheet.
Cash and Cash Equivalents	Cash and Cash EquivalentsCash and cash equivalents include cash and short-term investments, with maturities of less than 91 days from the date of purchase. Domestically, cash equivalents consist of AAA rated government money market funds, treasury discount notes, commercial paper, time deposits and certificates of deposit.
Investment in Marketable Debt Securities	Investments in Marketable Debt Securities The Company invests in marketable debt securities with active secondary or resale markets to ensure portfolio liquidity to fund current operations or satisfy other cash requirements as needed. Marketable debt securities are adjusted to fair value each quarter, and the unrealized gains and losses, net of tax, are included in accumulated other comprehensive income (loss) as a separate component of shareholders’ equity. The specific-identification method is used to determine the cost of debt securities sold and the amount of unrealized gains and losses reclassified out of accumulated other comprehensive income (loss) into earnings. The Company reviews its debt securities for impairment, including from risk of credit loss, each reporting period. The Company recognizes an unrealized loss on debt securities in net earnings when the impairment is determined to be other-than-
Capitalized Software, Leasehold Improvements and Equipment	Capitalized Software, Leasehold Improvements and Equipment Capitalized software, leasehold improvements and equipment, including significant improvements, are recorded at cost. Repairs and maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, or, in the case of leasehold improvements, the lease term, if shorter. Asset Category Estimated Capitalized software and computer equipment 2 to 3 Years Furniture and other equipment 5 to 7 Years Leasehold improvements 5 to 25 Years
Business Combinations	Business Combinations The purchase price of each acquisition is attributed to the assets acquired and liabilities assumed based on their fair values at the date of acquisition, including identifiable intangible assets that either arise from a contractual or legal right or are separable from goodwill. The Company usually uses the assistance of outside valuation experts to assist in the allocation of purchase price to identifiable intangible assets acquired. While outside valuation experts may be used, management has ultimate responsibility for the valuation methods, models and inputs used and the resulting purchase price allocation. The excess purchase price over the net tangible and identifiable intangible assets is recorded as goodwill and is assigned to the reporting unit(s) that is expected to benefit from the combination as of the acquisition date.
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets The Company assesses goodwill and indefinite-lived intangible assets for impairment annually as of October 1, or more frequently if an event occurs or circumstances change that would indicate that it is more likely than not that the fair value of a reporting unit or the fair value of an indefinite-lived intangible asset has declined below its carrying value. At October 1, 2020, the Company has two reporting units: North America and Europe. When the Company elects to perform a qualitative assessment and concludes it is not more likely than not that the fair value of the reporting unit is less than its carrying value, no further assessment of that reporting unit’s goodwill is necessary; otherwise, a quantitative assessment is performed and the fair value of the reporting unit is determined. If the carrying value of the reporting unit exceeds its fair value an impairment equal to the excess is recorded. For the Company’s annual goodwill test at October 1, 2020, a qualitative assessment of the North America and Europe reporting units’ goodwill was performed and it was concluded that it was more likely than not that the fair value of these reporting units was in excess of their respective carrying values. In the aggregate, ANGI Homeservices’ October 1, 2020 market capitalization of $5.5 billion exceeded its carrying value by approximately $4.3 billion. The primary factor that the Company considered in its qualitative assessment for its Europe reporting unit were valuations performed during 2020 that indicated a fair value in excess of the carrying value. The fair value based on the valuation that was most proximate to, but not as of, October 1, 2020 exceeded the carrying value of the Europe reporting unit by $131.4 million. The primary factor that the Company considered in its qualitative assessment for its North America reporting unit was the significant excess of the estimated fair value of the North America reporting unit over its carrying value. The fair value of the North America reporting unit was estimated by subtracting the fair value of the Europe reporting unit, based on the valuation described above, from the October 1, 2020 market capitalization of the Company; the estimated fair value of the North America reporting unit exceeded its carrying value by approximately $4.1 billion. The fair value of the Company’s Europe reporting unit is determined using both an income approach based on discounted cash flows (“DCF”) and a market approach when it tests goodwill for impairment, either on an interim basis or annual basis as of October 1 each year. 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 are based on the Company’s most recent forecast and budget and, for years beyond the budget, the Company’s estimates, which are based, in part, on forecasted growth rates. The discount rates used in the DCF analyses are intended to reflect the risks inherent in the expected future cash flows of the respective reporting units. Assumptions used in the DCF analyses, including the discount rate, are assessed based on the reporting units’ current results and forecasted future performance, as well as macroeconomic and industry specific factors. The discount rate used in determining the fair value of the Company’s Europe reporting unit was 15% in both 2020 and 2019. 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 a reporting unit. To determine a peer group of companies for our respective reporting units, we considered companies relevant in terms of consumer use, monetization model, margin and growth characteristics, and brand strength operating in their respective sectors.
Long-Lived Assets and Intangible Assets with Definite Lives	Long-Lived Assets and Intangible Assets with Definite Lives Long-lived assets, which consist of ROU assets, capitalized software, leasehold improvements and equipment and intangible assets with definite lives, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The carrying value of a long-lived asset is not recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the asset. If the carrying value is deemed not to be recoverable, an impairment loss is recorded equal to the amount by which the carrying value of the long-lived asset exceeds its fair value. Amortization of definite-lived intangible assets is computed either on a straight-line basis or based on the pattern in which the economic benefits of the asset will be realized.
Fair Value Measurements	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 Company’s non-financial assets, such as goodwill, intangible assets, ROU assets, capitalized software, leasehold improvements and equipment are adjusted to fair value only when an impairment is recognized. Such fair value measurements are based predominantly on Level 3 inputs.
Warranty Costs	Warranty Costs As part of certain of our revenue arrangements, we include warranties providing customers with assurance on the quality of the services provided. Under our warranties, we incur costs to ensure the services performed are up to the customers standard and/or to reimburse for any claim for damages submitted in accordance with our warranty terms and conditions. These costs are recorded as a component of cost of revenue in the Consolidated Statement of Operations.
Advertising Costs	Advertising CostsAdvertising costs are expensed in the period incurred (when the advertisement first runs for production costs that are initially capitalized) and represent online marketing, including fees paid to search engines, offline marketing, which is primarily television advertising and partner-related payments to those who direct traffic to our platforms.
Legal Costs	Legal Costs Legal costs are expensed as incurred.
Income Taxes	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, the income tax provision and/or benefit has been computed for 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 consolidated statement of cash flows. The Company accounts for income taxes under the liability method, and deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying values of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. A valuation allowance is provided if it is determined that it is more likely than not that the deferred tax asset will not be realized. The Company records interest, net of any applicable related income tax benefit, on potential income tax contingencies as a component of income tax expense. The Company evaluates and accounts for uncertain tax positions using a two-step approach. Recognition (step one) occurs when the Company concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustainable upon examination. Measurement (step two) determines the amount of benefit that is greater than 50% likely to be realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. De-recognition of a tax position that was previously recognized would occur when the Company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained.
Earnings Per Share	Earnings Per Share Basic earnings per share is computed by dividing net earnings attributable to ANGI Homeservices Inc. shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share reflects the potential dilution that could occur if stock appreciation rights, stock options and other commitments to issue common stock were exercised or equity awards vested resulting in the issuance of common stock that could share in the earnings of the Company.
Foreign Currency Translation and Transaction Gains and Losses	Foreign Currency Translation and Transaction Gains and Losses The financial position and operating results of foreign entities whose primary economic environment is based on their local currency are consolidated using the local currency as the functional currency. These local currency assets and liabilities are translated at the rates of exchange as of the balance sheet date, and local currency revenue and expenses of these operations are translated at average rates of exchange during the period. Translation gains and losses are included in accumulated other comprehensive income (loss) as a component of shareholders’ equity. Transaction gains and losses resulting from assets and liabilities denominated in a currency other than the functional currency are included in the consolidated statement of operations as a component of other income (expense), net. Translation gains and losses relating to foreign entities that are liquidated or substantially liquidated are reclassified out of accumulated other comprehensive income (loss) into earnings.
Stock-Based Compensation	Stock-Based CompensationStock-based compensation is measured at the grant date based on the fair value of the award and is expensed over the requisite service period.
Redeemable Noncontrolling Interests	Redeemable Noncontrolling Interests Noncontrolling interests in the consolidated subsidiaries of the Company are ordinarily reported on the consolidated balance sheet within shareholders’ equity, separately from the Company’s equity. However, securities that are redeemable at the option of the holder and not solely within the control of the issuer must be classified outside of shareholders’ equity. Accordingly, all noncontrolling interests that are redeemable at the option of the holder are presented outside of shareholders’ equity in the accompanying consolidated balance sheet. In connection with the acquisition of certain subsidiaries, management of these businesses has retained an ownership interest. The Company is party to fair value put and call arrangements with respect to these interests. These put and call arrangements allow management of these businesses to require the Company to purchase their interests or allow the Company to acquire such interests at fair value, respectively. The put arrangements do not meet the definition of a derivative instrument as the put agreements do not provide for net settlement. These put and call arrangements become exercisable by the Company and the counter-party at various dates. During the year ended December 31, 2020, one of these arrangements was exercised. No put and call arrangements were exercised during the year ended December 31, 2019, and one of these arrangements was exercised during the year ended December 31, 2018. Because these put arrangements are exercisable by the counter-party outside the control of the Company, to the extent that the fair value of these interests exceeds the value determined by normal noncontrolling interest accounting, the value of such interests is adjusted to fair value with a corresponding adjustment to additional paid-in capital. During the years ended December 31, 2020, 2019 and 2018, the Company recorded adjustments of $1.6 million, $8.2 million and $1.2 million, respectively, to increase these interests to fair value. Fair value determinations require high levels of judgment and are based on various valuation techniques, including market comparables and discounted cash flow projections.
Certain Risks and Concentrations	Certain Risks and Concentrations The Company’s business is subject to certain risks and concentrations including dependence on third-party technology providers, exposure to risks associated with online commerce security and credit card fraud. Financial instruments, which potentially subject the Company to concentration of credit risk, consist primarily of cash and cash equivalents and marketable debt securities. Cash and cash equivalents are maintained with financial institutions and are in excess of Federal Deposit Insurance Corporation insurance limits.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Accounting Pronouncements Adopted Adoption of Accounting Standards Update (“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. 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 consolidated 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 consolidated financial statements. Accounting Pronouncements Not Yet Adopted There are no recently issued accounting pronouncements that have not yet been adopted that are expected to have a material effect of the financial statement of the Company.

Accordingly, the weighted average basic shares outstanding were used to compute all earnings per share amounts. (b) If the effect is dilutive, weighted average common shares outstanding include the incremental shares that would be issued upon the assumed exercise of stock appreciation rights, stock options and subsidiary denominated equity and vesting of restricted stock units (“RSUs”). For the years ended December 31, 2019 and 2018, 5.5 million, and 3.1 million potentially dilutive securities, respectively, are excluded from the calculation of diluted earnings per share because their inclusion would have been anti-dilutive. (c) Market-based awards and performance-based stock units are considered contingently issuable shares. Shares issuable upon exercise or vesting of market-based awards and performance-based stock units are included in the denominator for earnings per share if (i) the applicable performance or market condition(s) has been met and (ii) the inclusion of the market-based award and performance-based stock units is dilutive for the respective reporting periods. For the years ended December 31, 2019 and 2018, 0.9 million, and 1.3 million shares underlying market-based awards and performance-based stock units, respectively, were excluded from the calculation of diluted earnings per share because the performance or market condition(s) had not been met.
