SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Consolidation The Company prepares its consolidated and combined financial statements in accordance with U.S. generally accepted accounting principles ("GAAP"). The Company's financial statements were prepared on a consolidated basis beginning September 29, 2017 and on a combined basis for periods prior thereto. The difference in presentation is due to the fact that the final steps of the legal reorganization, through which IAC contributed the HomeAdvisor business and cash to fund the cash consideration paid in the Combination to ANGI Homeservices Inc., were not completed, as planned, until immediately prior to September 29, 2017 . The preparation of the financial statements on a combined basis for periods prior thereto allows for the financial statements to be presented on a consistent basis for all periods presented. The combined financial statements have been prepared on a standalone basis and are derived from the historical consolidated financial statements and accounting records of IAC through September 29, 2017 . The combined financial statements reflect the results of operations and cash flows of the businesses comprising the HomeAdvisor business since their respective dates of acquisition by IAC. 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. The combined financial statements reflect the allocation to ANGI Homeservices of certain IAC corporate expenses relating to the HomeAdvisor business based on the historical consolidated financial statements and accounting records of IAC through September 29, 2017 . For the purpose of these financial statements, income taxes have been computed as if ANGI Homeservices filed tax returns on a standalone, separate basis. 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. The promissory note payable to a foreign subsidiary of IAC is included in "Long-term debt—related party" in the accompanying consolidated balance sheet and was settled during the first quarter of 2019. 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 and combined financial statements, including the basis on which the expenses have been allocated from IAC, are reasonable. However, the allocations may not reflect the expenses that we may have incurred as a standalone public company for the periods presented. Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its consolidated and combined financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates and judgments, including those related to: the fair values of cash equivalents and marketable debt securities; the carrying value of accounts receivable, including the determination of the allowance for doubtful accounts; the determination of revenue reserves; the carrying value of right-of-use assets ("ROU assets"); the useful lives and recoverability of definite-lived intangible assets and 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). These costs were expensed as incurred prior to January 1, 2018. 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 following table presents the impact of the adoption of ASU No. 2014-09 by segment under Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers , as reported, and ASC 605, Revenue Recognition , for the year ended December 31, 2018. Under ASC 606 Under ASC 605 Effect of adoption of ASU No. 2014-09 (In thousands) Revenue by segment: North America $ 1,062,171 $ 1,062,171 $ — Europe 70,070 70,070 — Total $ 1,132,241 $ 1,132,241 $ — Operating costs and expenses by segment: North America $ 984,069 $ 989,004 $ (4,935 ) Europe 84,266 84,271 (5 ) Total $ 1,068,335 $ 1,073,275 $ (4,940 ) Operating income (loss) by segment: North America $ 78,102 $ 73,167 $ 4,935 Europe (14,196 ) (14,201 ) 5 Total $ 63,906 $ 58,966 $ 4,940 Net earnings $ 77,507 $ 73,792 $ 3,715 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 (i) 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 fees from completed jobs sourced through the HomeAdvisor and Handy platforms, and (ii) HomeAdvisor service professional membership subscription fees. Consumer connection revenue varies based upon several factors, including the service requested, product experience offered and geographic location of service. The Company’s consumer connection revenue is generated and recognized when an in-network service professional is delivered a consumer match or when a job sourced through the HomeAdvisor and Handy platforms are completed. 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. 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 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) membership subscription fees from consumers and (iii) 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. 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, we modified the Handy terms and conditions so that Handy, rather than the service professional, has the contractual relationship with the consumer to deliver the service and Handy, rather than the consumer, has the contractual relationship with the service professional. Consumers request services and pay for such services directly through the Handy platform and then Handy fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. This change in contractual terms requires gross revenue accounting treatment effective January 1, 2020. Also, in the case of certain tasks, HomeAdvisor provides a pre-priced product offering, pursuant to which consumers can request services through a HomeAdvisor platform and pay HomeAdvisor for the services directly. HomeAdvisor then fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. Revenue from HomeAdvisor’s pre-priced product offering is also recorded on a gross basis effective January 1, 2020. In addition to changing the presentation of revenue to gross from net, the timing of revenue recognition will change for pre-priced jobs and will be later than the timing of existing consumer connection revenue for HomeAdvisor because we will not be able to record revenue, generally, until the service professional commences the job on our behalf. 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, 2019 and 2018 , the Company recognized expense of $56.8 million and $50.0 million , respectively, related to the amortization of these costs. The current contract assets are $35.1 million , $35.5 million and $29.7 million at December 31, 2019 and 2018 , and January 1, 2018 , respectively. The non-current contract asset balances are $4.0 million , $3.4 million and $4.2 million at December 31, 2019 and 2018 , and January 1, 2018 , 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 Receivable, Net of Allowance for Doubtful Accounts and Revenue Reserves Accounts receivable include amounts billed and currently due from customers. Accounts receivable outstanding longer than the contractual payment terms are considered past due. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivable that will not be collected. The allowance for doubtful accounts 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 to the Company. The term between the Company issuance of an invoice and payment due date is not significant. The Company also maintains allowances to reserve for potential credits issued to service professionals or other revenue adjustments. The amounts of these reserves are based primarily upon historical experience. Deferred Revenue Deferred revenue consists of 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 our performance obligation is one year or less. The deferred revenue balance is $58.4 million , $61.9 million and $64.1 million at December 31, 2019 and 2018 , and January 1, 2018 , respectively. During the years ended December 31, 2019 and 2018 , the Company recognized $61.0 million and $61.2 million of revenue that was included in the deferred revenue balance at December 31, 2018 and January 1, 2018 , respectively. The current deferred revenue balances are $58.2 million and $61.4 million at December 31, 2019 and 2018 , respectively. The non-current deferred revenue balances are $0.2 million and $0.5 million at December 31, 2019 and 2018 , 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, 2019 and 2018 . 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. We review our debt securities for impairment 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 we consider 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. We also consider whether we 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 no marketable debt securities at December 31, 2019 . At December 31, 2018 , marketable debt securities consisted of treasury discount notes. 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 Useful Lives 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 is $56.3 million and $37.6 million at December 31, 2019 and 2018 , 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, 2019 , 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, 2019 , a qualitative assessment of the North America and Europe reporting units' goodwill was performed because the Company concluded 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, 2019 market capitalization of $3.6 billion exceeded its carrying value by approximately $2.2 billion . The primary factor that the Company considered in its qualitative assessment for its Europe reporting unit were valuations performed during 2019 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, 2019 exceeded the carrying value of the Europe reporting unit by $113.3 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, 2019 market capitalization of the Company; the estimated fair value of the North America reporting unit exceeded its carrying value by approximately $2.1 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 2019 and 2018 . 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 27.5% in both 2019 and 2018 , and the royalty rates used ranged from 1.5% to 5.5% in both 2019 and 2018 . The 2019 , 2018 and 2017 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. 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 is $484.3 million , $334.7 million and $282.3 million for the years ended December 31, 2019 , 2018 and 2017 , respectively. Legal Costs Legal costs are expensed as incurred. Income Taxes ANGI Homeservices is included within IAC's tax group for purposes of federal and consolidated state income tax return filings. In all periods presented, current and deferred income tax provision/benefit have been computed for ANGI Homeservices on an as if standalone, separate return basis and payments to and refunds from IAC for its 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 and combined 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 stock that could share in the earnings of the Company. 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 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 and combined 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 compensation is measured at the grant d |
