Revenue from Contract with Customer [Abstract]
REVENUE RECOGNITION	REVENUE RECOGNITION General Revenue Recognition The Company accounts for a contract 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 is contractually due in exchange for those services or goods. Match Group Match Group revenue is primarily derived directly from users in the form of recurring subscriptions. Subscription revenue is presented net of credits and credit card chargebacks. Subscribers pay in advance, primarily by credit card or through mobile app stores, and, subject to certain conditions identified in our terms and conditions, generally all purchases are final and nonrefundable. Revenue is initially deferred and is recognized using the straight-line method over the term of the applicable subscription period, which primarily range from one to six months. Revenue is also earned from online advertising, the purchase of à la carte features and offline events. Online advertising revenue is recognized when an advertisement is displayed. Revenue from the purchase of à la carte features is recognized based on usage. Revenue associated with offline events is recognized when each event occurs. ANGI Homeservices ANGI revenue is primarily derived from (i) consumer connection revenue, which comprises fees paid by service professionals for consumer matches (regardless of whether the professional ultimately provides the requested service), and (ii) membership subscription fees paid by service professionals. Consumer connection revenue varies based upon several factors, including the service requested, type of match 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. Membership subscription revenue from service professionals 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. ANGI revenue is also derived from Angie's List (i) sales of time-based website, mobile and call center advertising to service professionals and (ii) membership subscription fees from consumers. 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. Video Revenue of businesses in this segment is generated primarily through subscriptions, media production and distribution, and advertising. Subscription fee revenue is recognized over the terms of the applicable subscription period, which are one month or one year, production revenue is recognized when control is transferred to the customer to broadcast or exhibit, and advertising revenue is recognized when an advertisement is displayed or over the advertising period. Applications Applications revenue largely consists of advertising revenue generated principally through the display of paid listings in response to search queries. The substantial majority of the paid listings displayed by our Applications businesses are supplied to us by Google pursuant to our services agreement with Google. Pursuant to this agreement, those of our Applications businesses that provide search services transmit search queries to Google, which in turn transmits a set of relevant and responsive paid listings back to these businesses for display in search results. This ad-serving process occurs independently of, but concurrently with, the generation of algorithmic search results for the same search queries. Google paid listings are displayed separately from algorithmic search results and are identified as sponsored listings on search results pages. Paid listings are priced on a price per click basis and when a user submits a search query through one of our Applications businesses and then clicks on a Google paid listing displayed in response to the query, Google bills the advertiser that purchased the paid listing directly and shares a portion of the fee charged to the advertiser with us. The Company recognizes paid listing revenue from Google when it delivers the user's click. In cases where the user’s click is generated due to the efforts of a third-party distributor, we recognize the amount due from Google as revenue and record a revenue share or other payment obligation to the third-party distributor as traffic acquisition costs. To a lesser extent, Applications revenue also consists of fees related to subscription downloadable desktop and mobile applications as well as display advertisements. Fees related to subscription downloadable desktop and paid mobile applications are generally recognized at the time of the sale when the software license is delivered. To the extent updates or maintenance is required or expected, revenue is recognized over the term of the applicable subscription period, which is primarily one or two years. Fees related to display advertisements are recognized when an advertisement is displayed. Publishing Publishing revenue consists principally of advertising revenue, which is generated primarily through the display of paid listings in response to search queries and display advertisements (sold directly and through programmatic ad sales). The majority of the paid listings that our Publishing businesses display are supplied to us by Google in the manner, and pursuant to the services agreement with Google, described above under "Applications." 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 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. Accounts Receivables, net of allowance for doubtful accounts and revenue reserves Accounts receivable include amounts billed and currently due from customers. The Company maintains an allowance for doubtful accounts to provide for the estimated amount of accounts receivables 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. The time between the Company issuance of an invoice and payments 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 allowances to reserve for potential credits issued to consumers or other revenue adjustments. The amounts of these reserves are based primarily upon historical experience. Deferred Revenue Deferred revenue consists of advance payments that are received or 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 generally 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 as of January 1, 2018 is $332.2 million. During the nine months ended September 30, 2018, the Company recognized $317.2 million of revenue that was included in the deferred revenue balance as of January 1, 2018. The deferred revenue balance as of June 30, 2018 is $377.2 million. During the three months ended September 30, 2018, the Company recognized $220.4 million of revenue that was included in the deferred revenue balance as of July 1, 2018. The current and non-current deferred revenue balances at September 30, 2018 are $381.4 million and $1.8 million, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying consolidated balance sheet. 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. For our multiple performance obligation arrangements that include functional intellectual property ("IP"), which comprise the downloadable apps and software of the Applications segment, the Company uses a residual approach to determine standalone selling prices for the functional IP. 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 and mobile app store fees, meet the requirements to be capitalized as a cost of obtaining a contract. Commissions paid to employees pursuant to certain sales incentive programs 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. The Company generally capitalizes and amortizes mobile app store fees over the term of the applicable subscription. During the three and nine months ended September 30, 2018, the Company recognized expense of $94.4 million and $254.3 million, respectively, related to the amortization of these costs. The current and non-current contract asset balances at September 30, 2018 are $69.9 million and $5.6 million, 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.
