Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Company Overview LendingTree, Inc. is currently the parent of LendingTree, LLC and several companies owned by LendingTree, LLC (collectively, "LendingTree" or the "Company"). LendingTree operates what it believes to be the leading online consumer platform that connects consumers with the choices they need to be confident in their financial decisions. The Company offers consumers tools and resources, including free credit scores, that facilitate comparison-shopping for mortgage loans, home equity loans and lines of credit, reverse mortgage loans, auto loans, credit cards, deposit accounts, personal loans, student loans, small business loans, insurance quotes and other related offerings. The Company primarily seeks to match in-market consumers with multiple providers on its marketplace who can provide them with competing quotes for loans, deposit products, insurance or other related offerings they are seeking. The Company also serves as a valued partner to lenders and other providers seeking an efficient, scalable and flexible source of customer acquisition with directly measurable benefits, by matching the consumer inquiries it generates with these providers. The consolidated financial statements include the accounts of LendingTree and all its wholly-owned entities, except Home Loan Center, Inc. ("HLC") subsequent to its bankruptcy filing on July 21, 2019 which resulted in the Company's loss of a controlling interest in HLC under applicable accounting standards. Intercompany transactions and accounts have been eliminated. Discontinued Operations The LendingTree Loans business, which consisted of originating various consumer mortgage loans through HLC (the "LendingTree Loans Business"), is presented as discontinued operations in the accompanying consolidated balance sheets, consolidated statements of operations and comprehensive income and consolidated cash flows for all periods presented. The notes accompanying these consolidated financial statements reflect the Company's continuing operations and, unless otherwise noted, exclude information related to the discontinued operations. See Note 20 — Discontinued Operations for additional information. Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). Certain prior year amounts have been reclassified to conform to current year presentation. See the discussion in Note 2 —Significant Accounting Policies for the impact of adopting Accounting Standards Update ("ASU") 2016-18 on the presentation of changes in restricted cash.

SIGNIFICANT ACCOUNTING POLICIES

SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES Revenue Recognition The Company derives its revenue primarily from match fees and closing fees. Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied and promised services have transferred to the customer. In identifying performance obligations, judgment is required around contracts where there was a possibility of bundled services and multiple parties. In applying judgment, the Company considers customer expectations of performance, materiality and the core principles of Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers. The Company's services are generally transferred to the customer at a point in time. Variable consideration is included in revenue if it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Revenue from Home products is primarily generated from upfront match fees paid by mortgage Network Partners that receive a loan request, and in some cases upfront fees for clicks or call transfers. Match fees and upfront fees for clicks and call transfers are earned through the delivery of loan requests that originated through the Company's websites or affiliates. The Company recognizes revenue at the time a loan request is delivered to the customer, provided that no significant obligations remain. Revenue recognition on match fees was not impacted by the adoption of ASC Topic 606 in the first quarter of 2018, as the Company's contractual right to the match fee consideration is contemporaneous with the satisfaction of the performance obligation to deliver a loan request to the customer. Revenue from Consumer products is generated by match and other upfront fees for clicks or call transfers, as well as from closing fees, approval fees and upfront service and subscription fees. Closing fees are derived from lenders on certain auto loans, business loans, personal loans and student loans when the lender funds a loan with the consumer. Prior to the adoption of ASC Topic 606, closed loan fees were recognized at the time the lender reported the closed loan to the Company, which could be several months after the original request was transmitted. Approval fees are derived from credit card issuers when the credit card consumer receives card approval from the credit card issuer. Prior to the adoption of ASC Topic 606, approval fees were recognized at the time the credit card issuer reported the card approval for the consumer to the Company, which is generally within two weeks after the consumer's request was transmitted. Upfront service fees and subscription fees are derived from consumers in the Company's credit services product. Upfront fees paid by consumers are recognized as revenue over the estimated time the consumer will remain a customer and receive services. Subscription fees are recognized over the period a consumer is receiving services. Under ASC Topic 606, the timing of recognizing revenue for closing fees and approval fees is accelerated to the point when a loan request or a credit card consumer is delivered to the customer, as opposed to when the consumer loan is closed by the lender or credit card approval is made by the issuer. The Company's contractual right to closing fees and approval fees is not contemporaneous with the satisfaction of the performance obligation to deliver a loan request or a credit card consumer to the customer. As such, the Company records a contract asset at each reporting period-end related to the estimated variable consideration on closing fees and approval fees for which the Company has satisfied the related performance obligation, but are still pending the loan closing or credit card approval before the Company has a contractual right to payment. This estimate is based on the Company's historical closing rates and historical time between when a consumer request for a loan or credit card is delivered to the lender or card issuer and when the loan is closed by the lender or approved by the card issuer. The time between satisfaction of the Company's performance obligation and when the Company's right to consideration becomes unconditional varies across products, but is generally less than 90 days for auto loans, personal loans, student loans and credit card approvals. The time between satisfaction of the Company's performance obligation and when the Company's right to consideration becomes unconditional for small business loans is generally less than 27 months. Revenue from the Company's Insurance products is primarily generated from upfront match fees, and upfront fees for website clicks or fees for calls. Match fees and upfront fees for clicks and call transfers are earned through the delivery of consumer requests that originated through the Company's websites or affiliates. The Company recognizes revenue at the time a consumer request is delivered to the customer, provided that no significant obligations remain. The Company's contractual right to the match fee consideration is contemporaneous with the satisfaction of the performance obligation to deliver a consumer request to the customer. Our payment terms vary by customer and services offered. The term between invoicing and when payment is due is generally 45 days or less. Sales commissions are incremental costs of obtaining contracts with customers. The Company expenses sales commissions when incurred as the duration of contracts with customers is less than one year, based on the right for either party to terminate the contract with less than one year's notice without compensation to either party. These costs are recorded within selling and marketing expense on the consolidated statements of operations and comprehensive income. For additional information on the adoption of ASC Topic 606, see the discussion over ASU 2014-09 in the section titled "Recently Adopted Accounting Pronouncements" within this Note. Cash and Cash Equivalents Cash and cash equivalents include cash and short-term, highly liquid money market investments with original maturities of three months or less. Restricted Cash Cash escrowed or contractually restricted for a specific purpose is designated as restricted cash. Accounts Receivable Accounts receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time accounts receivable are past due, previous loss history and the specific customer's current ability to pay its obligation. Accounts receivable are considered past due when they are outstanding longer than the contractual payment terms. Accounts receivable are written off when management deems them uncollectible. A reconciliation of the beginning and ending balances of the allowance for doubtful accounts is as follows (in thousands) : Year Ended December 31, 2019 2018 2017 Balance, beginning of the period $ 1,143 $ 675 $ 1,059 Charges to earnings 1,697 880 195 Write-off of uncollectible accounts receivable (1,374 ) (412 ) (579 ) Balance, end of the period $ 1,466 $ 1,143 $ 675 Segment Reporting The Company has three reportable segments: Home, Consumer and Insurance. Characteristics which were relied upon in making the determination of the reportable segments include the nature of the products, the organization's internal structure, and the information that is regularly reviewed by the CODM for the purpose of assessing performance and allocating resources. Property and Equipment Property and equipment, including internally-developed software and significant improvements, are recorded at cost less accumulated depreciation. Due to the rapid advancements in technology and evolution of company products, all internally-developed software is written-off at the end of its useful life. Repairs and maintenance and any gains or losses on dispositions are recognized as incurred in current operations. Depreciation is recorded on a straight-line basis to allocate the cost of depreciable assets to operations over their estimated service lives. The following table presents the estimated useful lives for each asset category: Asset Category Estimated Useful Lives Computer equipment and capitalized software 1 to 5 years Leasehold improvements Lesser of asset life or life of lease Furniture and other equipment 7 years Aircraft and automobile 5 to 10 years Software Development Costs Software development costs primarily include internal and external labor expenses incurred to develop the software that powers the Company's websites. Certain costs incurred during the application development stage are capitalized based on specific activities tracked, while costs incurred during the preliminary project stage and post-implementation/operation stage are expensed as incurred. Capitalized software development costs are amortized over an estimated useful life of one to five years . Goodwill and Indefinite-Lived Intangible Assets Goodwill acquired in business combinations is assigned to the reporting units that are expected to benefit from the combination as of the acquisition date. Goodwill and indefinite-lived intangible assets, consisting of certain trade names and trademarks, are not amortized. Rather, these assets are tested annually for impairment as of October 1, or more frequently upon the occurrence of certain events or substantive changes in circumstances. As part of its annual impairment testing of goodwill and indefinite-lived intangible assets, in each instance, the Company may elect to assess qualitative factors as a basis for determining whether it is necessary to perform the traditional quantitative impairment testing. If the Company’s assessment of these qualitative factors indicates that it is not more likely than not that the fair value of the reporting unit or indefinite-lived intangible asset is less than its carrying value, then no further testing is required. Otherwise, the goodwill reporting unit or long-lived intangible assets, as applicable, must be quantitatively tested for impairment. The quantitative test for goodwill impairment is determined using a two-step process. The first step is to compare the fair value of a reporting unit with its carrying amount, including goodwill. In performing the first step, the Company determines the fair value of its reporting units by using a market approach and a discounted cash flow ("DCF") analysis. Determining fair value using a DCF analysis requires the exercise of significant judgments, including judgments about appropriate discount rates, perpetual growth rates and the amount and timing of expected future cash flows. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not required. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is required to be performed to measure the amount of impairment, if any. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The quantitative impairment test for indefinite-lived intangible assets involves a comparison of the estimated fair value of the intangible asset with its carrying value. If the carrying value of the indefinite-lived intangible asset exceeds its estimated fair value, an impairment loss is recognized in an amount equal to that excess. The estimates of fair value of indefinite-lived intangible assets are determined using a DCF valuation analysis that employs a relief-from-royalty methodology in estimating the fair value of trade names and trademarks. Significant judgments inherent in this analysis include the determination of royalty rates, discount rates, perpetual growth rates and the amount and timing of future revenues. At October 1, 2019, the Company performed the first step of the quantitative goodwill impairment test and found that the fair value of each reporting unit exceeded its carrying amount, indicating no goodwill impairment. The Company changed its operating segments in the fourth quarter of 2019 and accordingly changed its reporting units. At December 31, 2019, the Company performed the first step of the quantitative goodwill impairment test and found that the fair value of each reporting unit exceeded its carrying amount, indicating no goodwill impairment. Results of the October 1, 2019 qualitative annual impairment tests for the indefinite-lived intangible assets indicated that it is not more likely than not that the fair value of the assets were each less than their respective carrying values. Accordingly, no further testing was required. Results of the October 1, 2018 qualitative annual impairment tests indicated that it is not more likely than not that the fair value of the goodwill and the indefinite-lived intangible assets were each less than their respective carrying values. Accordingly, no further testing was required. Long-Lived Assets and Intangible Assets with Definite Lives Long-lived assets include property and equipment, definite-lived intangible assets and operating lease right-of-use assets. Amortization of definite-lived intangible assets is recorded on a straight-line basis over their estimated lives. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. The carrying amount 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 amount is deemed to not be recoverable, an impairment loss is recorded as the amount by which the carrying amount of the long-lived asset exceeds its fair value. At December 31, 2019 and 2018, the Company performed its review of impairment triggering events for long-lived assets and determined that a triggering event had not occurred. Assets and Liabilities Held for Sale The Company classifies assets or disposal groups to be sold as held for sale in the period in which all of the following criteria are met: • Management, having the authority to approve the action, commits to a plan to sell the asset or disposal group; • The asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets or disposal groups; • An active program to locate a buyer and other actions required to complete the plan to sell the asset or disposal group have been initiated; • The sale of the asset or disposal group is probable, and transfer of the asset or disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the asset or disposal group beyond one year; • The asset or disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and • Actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A long-lived asset or disposal group that is classified as held for sale is initially measured at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. The fair value of a long-lived asset or disposal group, less any costs to sell, is assessed each reporting period it remains classified as held for sale and any subsequent changes are reported as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held for sale. Fair Value Measurements The Company categorizes its assets and liabilities measured at fair value into a fair value hierarchy that prioritizes the assumptions used in pricing the asset or liability into the following three levels: • Level 1 : Observable inputs, such as quoted prices for identical assets and liabilities in active markets obtained from independent sources. • Level 2 : Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted 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. • Level 3 : Unobservable inputs for which there is little or no market data and which require the Company to develop its own assumptions, based on the best information available under the circumstances, about the assumptions market participants would use in pricing the asset or liability. The Company's non-financial assets, such as goodwill, intangible assets and property and equipment are recorded at fair value upon acquisition. These assets are remeasured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs. Contingent consideration payments related to acquisitions are measured at fair value each reporting period using Level 3 unobservable inputs. The Company's estimates of fair value are based upon assumptions believed to be reasonable but which are uncertain and involve significant judgments by management. Any changes in the fair value of these contingent consideration payments are included in operating income in the consolidated statements of operations and comprehensive income. Cost of Revenue Cost of revenue consists primarily of expenses associated with compensation and other employee-related costs (including stock-based compensation) related to internally-operated customer call centers, third-party customer call center fees, costs for online advertising resold to third parties, credit scoring fees, credit card fees, website network hosting and server fees. Product Development Product development expense consists primarily of compensation and other employee-related costs (including stock-based compensation) and third-party labor costs that are not capitalized, for employees and consultants engaged in the design, development, testing and enhancement of technology. Advertising Advertising costs are expensed in the period incurred (except for production costs which are initially capitalized and then recognized as expense when the advertisement first runs) and principally represent offline costs, including television, print and radio advertising, and online advertising costs, including fees paid to search engines and distribution partners. Advertising expense was $688.2 million , $469.9 million and $410.8 million for the years ended December 31, 2019 , 2018 and 2017 , respectively, and is included in selling and marketing expense on the consolidated statements of operations and comprehensive income. Income Taxes Income taxes are accounted for 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 amounts of existing assets and liabilities and their respective tax bases. In estimating future tax consequences, all expected future events are considered. 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 on deferred tax assets if it is determined that it is more likely than not that the deferred tax asset will not be realized. Interest is recorded on potential tax contingencies as a component of income tax expense and recorded net of any applicable related income tax benefit. For the years ended December 31, 2019 , 2018 and 2017 , the Company followed the incremental or "with" and "without" approach to intraperiod tax allocation for determination of the amount of tax benefit to allocate to continuing operations as prescribed in ASC 740-20-45-7. In accordance with the accounting standard for uncertainty in income taxes, liabilities for uncertain tax positions are recognized based on the two-step process prescribed by the accounting standards. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Effective January 1, 2018, the Company changed the method used to estimate the deduction for prepaid marketing and advertising costs. This change in methodology impacts the timing of the tax deductibility of these related costs. The Company historically estimated these expenses to be deductible if the services were provided within 12 months of payment. Under the proposed method of accounting, the Company will take into account only prepaid marketing and advertising as the Company makes payment for the services to the extent that the payment is due and the services are reasonably expected by the Company to be provided to the applicant within 3 ½-months after the date of payment as authorized by Treas. Reg. §1.461-4(d)(6)(ii). The Company has accounted for this change as a change in accounting method and recorded a cumulative impact of $1.0 million as a deferred tax liability to be recognized over four years. Effective January 1, 2017, the Company changed the method used to estimate the deduction for internally developed software. This change in methodology impacts the timing of the tax deductibility of these related costs. The Company historically capitalized these expenses and amortized them over three years. Under the proposed method of accounting, the Company will treat costs attributable to internally developed software as current expenses and take them into account in full in accordance with Section 5.01(1) of Rev. Proc. 2000-50 and rules similar to those applicable under Section 174(a). The Section 481(a) adjustment is the cumulative difference between the present method and the proposed method of accounting computed as of the first day of the year of change, January 1, 2017 and was reflected in the timely filed income tax return during 2018 related to the period of change. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides guidance on accounting for the tax effect of the Tax Cuts and Jobs Act ("TCJA"). SAB 118 provides a measurement period that should not extend beyond one year from the TCJA enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the TCJA for which the accounting under ASC 740 is complete. To the extent that a company's accounting for certain income tax effects of the TCJA is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. In accordance with SAB 118, the Company determined that the $ 9.1 million of the deferred tax expense recorded in connection with the remeasurement of certain deferred tax assets and liabilities was a provisional amount and a reasonable estimate at December 31, 2017. During the fourth quarter of the year ended December 31, 2018, the Company finalized the computations of the income tax effects of the Act. As such, in accordance with SAB 118, the Company's accounting for the effects of the Act is complete. The Company did not significantly adjust provisional amounts recorded in 2017 and the SAB 118 measurement period subsequently ended on December 22, 2018. Although the Company no longer considers these amounts to be provisional, the determination of the Act's income tax effects may change following future legislation or further interpretation of the Act based on future guidance from the Internal Revenue Service and state tax authorities. Stock-Based Compensation The forms of stock-based awards granted to LendingTree employees are principally restricted stock units ("RSUs"), RSUs with performance conditions, stock options and stock options with performance conditions. Further, stock options with market conditions, restricted stock awards ("RSAs") with performance conditions and RSAs with market conditions have been granted to the Company's Chairman and Chief Executive Officer. RSUs are awards in the form of units, denominated in a hypothetical equivalent number of shares of LendingTree common stock and with the value of each award equal to the fair value of LendingTree common stock at the date of grant. RSUs may be settled in cash, stock or both, as determined by the Company's Compensation Committee at the time of grant. The Company does not have a history of settling these awards in cash. Each stock-based award is subject to service-based vesting, where a specific period of continued employment must pass before an award vests. The Compensation Committee can modify the vesting provisions of an award. Certain awards also include performance-based vesting, where certain performance targets set at the time of grant must be achieved before an award vests. LendingTree recognizes as expense non-cash compensation for all stock-based awards for which vesting is considered probable. Forfeitures are recognized when they occur. For service-based awards, non-cash compensation is measured at fair value on the grant date and expensed ratably over the vesting term. The fair value of each stock option award without a market condition is estimated using the Black-Scholes option pricing model, while the fair value of an RSU or restricted stock award is measured as the closing common stock price at the time of grant. For performance-based grants, the fair value is measured on the grant date and recognized as non-cash compensation expense, considering the probability of the targets being achieved. Performance-based grants with a market condition are generally valued using a Monte Carlo simulation model. Excess tax benefits and deficiencies that arise due to the difference in the measure of stock compensation and the amount deductible for tax purposes are recorded in income tax expense within the consolidated statement of operations and comprehensive income, and are classified as a component of operating cash flows within the consolidated statements of cash flows. Litigation Settlements and Contingencies Litigation settlements and contingencies consists of expenses related to actual or anticipated litigation settlements. The Company is involved in legal proceedings on an ongoing basis. If the Company believes that a loss arising from such matters is probable and can be reasonably estimated, the estimated liability is accrued in the consolidated financial statements. If only a range of estimated losses can be determined, an amount within the range is accrued that, in the Company's judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, the low end of the range is accrued. For those proceedings in which an unfavorable outcome is reasonably possible but not probable, an estimate of the reasonably possible loss or range of losses or a conclusion that an estimate of the reasonably possible loss or range of losses arising directly from the proceeding (i.e., monetary damages or amounts paid in judgment or settlement) are not material is disclosed. Legal expenses associated with these matters are recognized as incurred. Accounting Estimates Management is required to make certain estimates and assumptions during the preparation of the consolidated financial statements in accordance with GAAP. These estimates and assumptions impact the reported amount of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amount of net earnings during any period. Actual results could differ from those estimates. Significant estimates underlying the accompanying consolidated financial statements, including discontinued operations, include: loan loss obligations; the recoverability of long-lived assets, goodwill and intangible assets; the determination of income taxes payable and deferred income taxes, including related valuation allowances; fair value of assets acquired in a business combination; contingent consideration related to business combinations; litigation accruals; HLC ownership related claims; contract assets; various other allowances, reserves and accruals; and assumptions related to the determination of stock-based compensation. Certain Risks and Concentrations LendingTree'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 at December 31, 2019 , consist primarily of cash and cash equivalents and accounts receivable, as disclosed in the consolidated balance sheet. Cash and cash equivalents are in excess of Federal Deposit Insurance Corporation insurance limits, but are maintained with quality financial institutions of high credit. The Company requires certain Network Partners to maintain security deposits with the Company, which in the event of non-payment, would be applied against any accounts receivable outstanding. Due to the nature of the mortgage lending industry, interest rate fluctuations may negatively impact future revenue from the Company's marketplace. For the year ended December 31, 2019 , one network partner accounted for 12% of total consolidated revenue, all of which was recorded within the Insurance segment. No Network Partners accounted for more than 10% of total consolidated revenue for the year ended December 31, 2018 . For the year ended December 31, 2017 , another network partner accounted for 11% of total consolidated revenue, which was recorded within the Home and Consumer segments. Lenders and lead purchasers participating on the Company's marketplace can offer their products directly to consumers through brokers, mass marketing campaigns or through other traditional methods of credit distribution. These lenders and lead purchasers can also offer their products online, either directly to prospective borrowers, through one or more online competitors, or both. If a significant number of potential consumers are able to obtain loans and other products from Network Partners without utilizing the Company's services, the Company's ability to generate revenue may be limited. Because the Company does not have exclusive relationships with the Network Partners whose loans and other financial products are offered on its online marketplace, consumers may obtain offers from these Network Partners without using its service. Other than a support services office in India, the Company's operations are geographically limited to and dependent upon the economic condition of the United States. Recently Adopted Accounting Pronouncements In June 2018, the FASB issued ASU 2018-07 which simplifies the accounting for nonemployee share-based payments by expanding the scope of ASC Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. Under the new guidance, most of the initial and subsequent measurement for such payments to nonemployees is aligned with the requirements for share-based payments to employees. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018, and early adoption was permitted. Entities must transition to the new guidance through a c

ASSETS HELD FOR SALE

ASSETS HELD FOR SALE	12 Months Ended
	Dec. 31, 2019
Discontinued Operations and Disposal Groups [Abstract]
ASSETS HELD FOR SALE	ASSETS HELD FOR SALE In December 2016, the Company acquired two office buildings in Charlotte, North Carolina for $23.5 million in cash, which included $0.1 million in acquisition-related costs which were capitalized. The buildings were acquired with the intent to use such buildings as the Company's corporate headquarters and rent any unused space. In November 2018, the Company's Board of Directors approved a plan to sell the two office buildings. The properties were classified as current assets held for sale in the consolidated balance sheet for December 31, 2018. The Company sold these buildings to an unrelated third party in the second quarter of 2019 for a sale price of $24.4 million , and the Company incurred closing fees of $0.3 million . The Company recognized a gain of $2.7 million on the sale within general and administrative expense in the consolidated statement of operations and comprehensive income. At the time the buildings were classified as held for sale, and at time of sale, they were associated with the Company's then one reportable segment. Property and equipment classified as held for sale at December 31, 2018 is as follows (in thousands) : Amount Land $ 5,818 Building 14,984 Site improvements 950 Computer equipment and capitalized software 166 Furniture and other equipment 145 Total gross property and equipment 22,063 Accumulated depreciation (1,278 ) Total property and equipment, net $ 20,785 Intangible assets classified as held for sale at December 31, 2018 is as follows (in thousands) : Amount Tenant leases $ 961 Total gross intangible assets 961 Accumulated amortization (468 ) Total intangible assets, net $ 493 The LendingTree Loans Business is presented as discontinued operations in the accompanying financial statements. The LendingTree Loans Business originated various consumer mortgage loans through HLC. On June 6, 2012, the Company sold substantially all of the operating assets of HLC, including the LendingTree Loans Business, for $55.9 million in cash to a wholly-owned subsidiary of Discover Financial Services ("Discover"). Discover generally did not assume liabilities of HLC that arose before the closing date, except for certain liabilities directly related to assets Discover acquired. Of the purchase price received, a portion was deposited in escrow in accordance with the purchase agreement with Discover for certain loan loss obligations that remained with HLC following the sale. During 2018, the remaining funds in escrow were released to HLC in accordance with the terms of the purchase agreement with Discover. Upon closing of the sale of substantially all of the operating assets of HLC on June 6, 2012, HLC ceased to originate consumer loans. Liability for losses on previously sold loans remains with HLC and is discussed below. Litigation settlements and contingencies and legal fees associated with ongoing related bankruptcy and legal proceedings against the Company are included in discontinued operations in the accompanying financial statements. Home Loan Center, Inc. Bankruptcy Filing On June 21, 2019, the U.S. District Court of Minnesota entered judgment in ResCap Liquidating Trust v. Home Loan Center, Inc. , against HLC for $68.5 million , see Litigation Related to Discontinued Operations below. The judgment against HLC exceeded the assets of HLC, which were $11.2 million at July 21, 2019, including cash of $5.9 million . On July 19, 2019, HLC appealed the judgment to the United States Court of Appeals for the Eighth Circuit. On July 21, 2019, at the direction of the sole independent director of HLC, HLC voluntarily filed a petition under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) with the U.S. Bankruptcy Court in the Northern District of California in San Jose, California (the “Bankruptcy Court”) in order to preserve assets for the benefit of all creditors of HLC. On September 16, 2019, the Bankruptcy Court converted the bankruptcy to Chapter 7 of the Bankruptcy Code and appointed a Trustee to liquidate HLC’s assets. HLC’s filing under the Bankruptcy Code creates an automatic stay of enforcement of the judgment entered against HLC by the Minnesota court in ResCap Liquidating Trust v. Home Loan Center, Inc. described above and in Litigation Related to Discontinued Operations below. As a result of the voluntary petition, LendingTree, LLC was, as of the initial July 21, 2019 bankruptcy petition filing date, no longer deemed to have a controlling interest in HLC under applicable accounting standards. As a result, HLC and its consolidated subsidiary were deconsolidated from the Company’s consolidated financial statements as of July 21, 2019. The effect of such deconsolidation was the elimination of the consolidated assets and liabilities of HLC (and its consolidated subsidiary) from the Company’s consolidated balance sheets. Upon deconsolidation, in 2019 the Company recognized a loss of $5.5 million which includes a net gain of $4.5 million related to the removal of HLC's (and its consolidated subsidiary's) assets and liabilities and the recognition of a liability of $10.0 million related to LendingTree LLC's ownership in HLC. No consideration was received by the Company as a result of the deconsolidation. The derecognition of HLC’s cash of $5.9 million removed from the consolidated balance sheet on the deconsolidation date of July 21, 2019 is included within cash flows from operating activities attributable to discontinued operations in the accompanying consolidated statement of cash flows. HLC has indicated that it believes that it has claims against HLC’s sole shareholder, LendingTree, LLC, and certain of its officers and directors, relating to the declaration of a dividend by HLC in January 2016 of $40.0 million . The Company is obligated to advance any expenses to the officers and directors related to these claims and to indemnify them to the maximum extent permitted by law. LendingTree, LLC believes the declaration of the dividend was proper, that the amounts paid to LendingTree, LLC following such declaration are not subject to recovery by HLC and that any claims by HLC relating to such dividend declaration are without merit. LendingTree, LLC intends to vigorously contest such claims. During the third quarter of 2019, LendingTree, LLC made a settlement offer to HLC after it filed for bankruptcy for $31.0 million for the release of any and all claims against the Company, including the dividend claim. LendingTree estimates the range of potential losses related to the dividend matter to be $0.0 million to $40.0 million plus a potential award of prejudgment interest. An estimated liability of $31.0 million is included in the accompanying consolidated balance sheet as of December 31, 2019 related to LendingTree LLC's ownership in HLC. HLC’s voluntary petition under the Bankruptcy Code does not represent an event of default under LendingTree, LLC’s Second Amended and Restated Credit Agreement dated as of December 10, 2019 or the Company’s indenture dated May 31, 2017 with respect to the Company’s 0.625% Convertible Senior Notes due 2022. Loan Loss Obligations Prior to the sale of its LendingTree Loans Business on June 6, 2012, HLC sold loans it originated through its LendingTree Loans Business to investors on a servicing-released basis, so the risk of loss or default by the borrower was generally transferred to the investor. However, HLC was required by these investors to make certain representations and warranties relating to credit information, loan documentation and collateral. These representations and warranties may extend through the contractual life of the loan. If underwriting deficiencies, borrower fraud or documentation defects, arising prior to the sale of the loan by HLC to such investor, are discovered in individual loans, HLC may be obligated to repurchase the respective loan or indemnify such investor for any losses from borrower defaults if such deficiency or defect cannot be cured within the contractually specified period following discovery. HLC continues to be liable for these indemnification obligations, repurchase obligations and premium repayment obligations following the sale of substantially all of its operating assets, including the LendingTree Loans Business, in the second quarter of 2012. The liability for losses on previously sold loans was presented as current liabilities of discontinued operations in the accompanying consolidated balance sheet as of December 31, 2018. Additionally, LendingTree guaranteed certain loans sold to investors in the event that HLC is unable to satisfy its repurchase and warranty obligations related to such loans. Litigation Related to Discontinued Operations Residential Funding Company ResCap Liquidating Trust v. Home Loan Center, Inc., Case No. 14-cv-1716 (U.S. Dist. Ct., Minn.), successor to Residential Funding Company, LLC v Home Loan Center, Inc., No. 13-cv-3451 (U.S. Dist. Ct., Minn.). On or about December 16, 2013, Home Loan Center, Inc. was served in the original captioned matter, which involves claims of Residential Funding Company, LLC ("RFC") for damages for breach of contract and indemnification for certain residential mortgage loans as well as residential mortgage-backed securitizations ("RMBS") containing mortgage loans. RFC asserted that, beginning in 2008, RFC faced massive repurchase demands and lawsuits from purchasers or insurers of the loans and RMBS that RFC had sold. RFC filed for bankruptcy protection in May 2012. Plaintiff alleged that, after RFC filed for Chapter 11 protection, hundreds of proofs of claim were filed, many of which mirrored the litigation filed against RFC prior to its bankruptcy. In December 2013, the United States Bankruptcy Court for the Southern District of New York entered an Order confirming the Second Amended Joint Chapter 11 Plan Proposed by Residential Capital, LLC et al. and the Official Committee of Unsecured Creditors. Plaintiff then began filing substantially similar complaints against approximately 80 of the loan originators from whom RFC had purchased loans, including HLC, in federal and state courts in Minnesota and New York. In each case, plaintiff claimed that the defendant is liable for a portion of the global settlement in RFC’s bankruptcy. Plaintiff asserted two claims against HLC: (1) breach of contract based on HLC’s alleged breach of representations and warranties concerning the quality and characteristics of the mortgage loans it sold to RFC; and (2) contractual indemnification for alleged liabilities, losses, and damages incurred by RFC arising out of purported defects in loans that RFC purchased from HLC and sold to third parties. Plaintiff alleged that the “types of defects” contained in the loans it purchased from HLC included “income misrepresentation, employment misrepresentation, appraisal misrepresentations or inaccuracies, undisclosed debt, and missing or inaccurate documents.” Plaintiff sought damages of up to $61.0 million plus attorney's fees and prejudgment interest. HLC denied the material allegations of the complaint and asserted numerous defenses thereto. The matter went to trial in the fourth quarter of 2018 and the jury returned a verdict of $28.7 million in favor of plaintiff. On June 21, 2019, the U.S. District Court in Minnesota entered judgment against HLC for $68.5 million . The judgment is comprised of: (i) $28.7 million in damages awarded by the jury; (ii) $14.1 million in pre-verdict interest; (iii) $23.1 million in attorneys' fees and costs, and (iv) $2.6 million in post-verdict, prejudgment interest. HLC’s filing under the Bankruptcy Code discussed above in Home Loan Center, Inc. Bankruptcy Filing creates an automatic stay of enforcement of the judgment entered against HLC by the U.S. District Court in Minnesota. On August 27, 2019, plaintiff filed a lawsuit captioned ResCap Liquidating Trust v. LendingTree, LCC, et al., Case No. 19-cv-2360 (U.S. Dist. Ct., Minn.) , seeking to hold the Company liable for the judgment against HLC, under assumption of liability, agency and alter ego theories. The Company believes that these claims lack merit and intends to defend this action vigorously. On October 17, 2019, the Company filed a motion to dismiss the liability and agency claims, and oral arguments with respect to such motion were held on January 10, 2020. Lehman Brothers Holdings, Inc. Lehman Brothers Holdings Inc. v. 1st Advantage Mortgage, LLC et al., Case No. 08-13555 (SCC), Adversary Proceeding No. 16-01342 (SCC) (Bankr. S.D.N.Y.). In February 2016, Lehman Brothers Holdings, Inc. (“LBHI”) filed an Adversary Complaint against HLC and approximately 149 other defendants (the "Complaint"). In December 2018, LBHI amended its complaint against HLC. The amended complaint references approximately 370 allegedly defective mortgage loans sold by HLC with purported "Claim Amounts" totaling $40.2 million . LBHI alleges it settled all such claims and is seeking indemnification from HLC for LBHI’s purported losses and liabilities associated with such settlements, plus prejudgment interest, attorneys’ fees, litigation costs and other expenses. The amended complaint does not specify the amount of LBHI’s purported damages. On December 4, 2019, LBHI filed a $44.7 million proof of claim in HLC’s bankruptcy seeking recovery for the claims asserted in the lawsuit. The Company believes that these claims lack merit and understands that HLC intends to defend this action vigorously. HLC’s filing under the Bankruptcy Code discussed above in Home Loan Center, Inc. Bankruptcy Filing creates an automatic stay of this proceeding. Financial Information of Discontinued Operations The components of net loss reported as discontinued operations in the accompanying consolidated statements of operations and comprehensive income are as follows (in thousands) : Year Ended December 31, 2019 2018 2017 Revenue $ — $ — $ (750 ) Gain from removal of HLC's assets and liabilities 4,515 — — Other operating expenses (35,002 ) (16,228 ) (5,159 ) Loss before income taxes (30,487 ) (16,228 ) (5,909 ) Income tax benefit 8,855 3,408 2,069 Net loss $ (21,632 ) $ (12,820 ) $ (3,840 ) Losses from discontinued operations included all activity of HLC prior to bankruptcy, including litigation settlements, contingencies and legal fees associated with legal proceedings, as well as a gain upon deconsolidation due to the accounting effect of HLC’s bankruptcy filing on the consolidated financial statements. The results of discontinued operations also include litigation settlements and contingencies and legal fees associated with ongoing legal proceedings against LendingTree Inc. or LendingTree LLC that arose due to the LendingTree Loans Business or the HLC bankruptcy filing.

BUSINESS ACQUISITIONS	12 Months Ended

Business Combinations [Abstract]
BUSINESS ACQUISITIONS	BUSINESS ACQUISITIONS 2019 Acquisition ValuePenguin On January 10, 2019 , the Company acquired Value Holding, Inc., the parent company of ValuePenguin Inc. ("ValuePenguin"), a personal finance website that offers consumers objective analysis on a variety of financial topics from insurance to credit cards. The Company made an upfront cash payment of $106.1 million at the closing of the transaction, funded through $90.0 million drawn on the Company's revolving credit facility and the balance using cash on hand. The purchase price of $106.2 million is comprised of the upfront cash payment of $106.1 million and a $0.1 million post-closing payment for working capital settlement. The acquisition has been accounted for as a business combination. In 2019, the Company completed the determination of the final allocation of purchase price to the assets acquired and liabilities assumed as follows (in thousands) : Fair Value Net working capital $ 2,502 Fixed assets 68 Intangible assets 31,600 Goodwill 71,739 Net noncurrent assets 323 Total purchase price $ 106,232 The Company primarily used the income approach for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions. Market participants are buyers and sellers unrelated to the Company and fair value is determined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction at the measurement date. The acquired intangible assets are definite-lived assets consisting of developed technology, content and trademarks and tradenames. The estimated fair values of the developed technology were determined using the cost replacement method, the content was determined using the excess earnings method, and the trademarks and tradenames were determined using the relief from royalty method. The estimated fair value of the intangible assets are based on estimates for content lifecycles, estimates for revenue growth rates, estimates for future cash flows, the probability weighting of scenarios and discount rates, known at the acquisition date, which management believes are reasonable. The fair value of the intangible assets with definite lives is as follows (dollars in thousands) : Fair Value Weighted Average Amortization Life Technology $ 4,200 3 years Content 26,100 3 years Trademarks and tradenames 1,300 5 years Total intangible assets $ 31,600 3.1 years The Company recorded goodwill of $71.7 million , which represents the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of the liabilities assumed. The goodwill is primarily attributable to ValuePenguin as a going concern, which represents the ability of the Company to earn a higher return on the collection of assets and business of ValuePenguin than if those assets and business were to be acquired and managed separately. The benefit of access to the workforce is an additional element of goodwill. The goodwill was recorded in the Company’s then one reportable segment. For income tax purposes, the Company accounted for the acquisition as an asset purchase which would indicate the goodwill will be tax deductible. Subsequent to the acquisition date, the Company’s consolidated results of operations include the results of the acquired ValuePenguin business. In 2019 , the Company’s consolidated results of operations include revenue of $19.8 million attributable to the ValuePenguin business. In the first six months of 2019 , net income from continuing operations attributable to the ValuePenguin business was $3.1 million . Due to the integration of the ValuePenguin business subsequent to the acquisition, earnings of the acquired ValuePenguin business beginning in the third quarter of 2019 is impracticable to determine with sufficient accuracy. Acquisition-related costs were $0.1 million in 2019 and are included in general and administrative expense on the consolidated statement of operations and comprehensive income. 2018 Acquisitions QuoteWizard On October 31, 2018 , the Company acquired QuoteWizard.com, LLC ("QuoteWizard"), one of the largest insurance comparison marketplaces in the growing online insurance advertising market. QuoteWizard services clients by driving consumers to insurance companies’ websites, providing leads to agents and carriers, as well as phone transfers of consumers into carrier call centers. The Company paid $299.9 million in initial cash consideration, funded through $174.9 million of cash on hand and $125.0 million drawn on the Company's revolving credit facility, and could make up to three additional earnout payments, each ranging from zero to $23.4 million , based on certain defined operating results during the earnout periods November 1, 2018 through October 31, 2019, November 1, 2019 through October 31, 2020, and November 1, 2020 through October 31, 2021. These additional payments, to the extent earned, will be payable in cash. The purchase price of $313.4 million is comprised of the upfront cash payment of $299.9 million , $13.9 million for the estimated fair value of the earnout payments, and a $0.4 million post-closing receipt for working capital settlement. In the fourth quarter of 2019, the Company paid $23.4 million related to the earnout payment for the period of November 1, 2018 through October 31, 2019, of which $13.9 million is included within cash flows from financing activities and $9.5 million is included within cash flows from operating activities on the consolidated statement of cash flows. As of December 31, 2019 , the estimated fair value of the contingent consideration totaled $24.4 million , which is included in non-current contingent consideration in the accompanying consolidated balance sheet. The estimated fair value of the contingent consideration payments is determined using an option pricing model. The estimated value of the contingent consideration is based upon available information and certain assumptions, known at the time of this report, which management believes are reasonable. Any differences in the actual contingent consideration payments will be recorded in operating income in the consolidated statements of operations and comprehensive income. During 2019 and 2018, the Company recorded $27.1 million and $6.8 million , respectively, of contingent consideration expense in the consolidated statements of operations and comprehensive income due to the change in estimated fair value of the contingent consideration. The acquisition has been accounted for as a business combination. In 2019, the Company completed the determination of the final allocation of purchase price to the assets acquired and liabilities assumed as follows (in thousands) : Fair Value Net working capital $ 8,521 Fixed assets 1,509 Intangible assets 120,400 Goodwill 182,896 Other noncurrent assets 29 Total purchase price $ 313,355 The Company primarily used the income approach for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions. Market participants are buyers and sellers unrelated to the Company and fair value is determined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction at the measurement date. The acquired intangible assets are definite-lived assets consisting of developed technology, customer relationships, content and trademarks and tradenames. The estimated fair values of the developed technology were determined using the excess earnings method, the customer relationships were determined using the distributor method, the content was determined using the cost replacement method, and the trademarks and tradenames were determined using the relief from royalty method. The fair value of the intangible assets with definite lives is as follows (dollars in thousands) : Fair Value Weighted Average Amortization Life Technology $ 68,900 4 years Customer lists 42,700 14.7 years Content 1,000 3 years Trademarks and tradenames 7,800 5 years Total intangible assets $ 120,400 7.9 years The Company recorded goodwill of $182.9 million , which represents the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of the liabilities assumed. The goodwill is primarily attributable to QuoteWizard as a going concern, which represents the ability of the Company to earn a higher return on the collection of assets and business of QuoteWizard than if those assets and business were to be acquired and managed separately. The benefit of access to the workforce is an additional element of goodwill. The goodwill was recorded in the Company’s then one reportable segment. For income tax purposes, the acquisition was an asset purchase and the goodwill will be tax deductible. Acquisition-related costs were $4.8 million in 2018 and are included in general and administrative expense on the consolidated statement of operations and comprehensive income. The unaudited pro forma financial results for the years ended December 31, 2018 and 2017 below combine the consolidated results of the Company and QuoteWizard, giving effect to the acquisition as if it had been completed on January 1, 2017. This unaudited pro forma financial information is presented for informational purposes only and is not indicative of future operations or results had the acquisition been completed as of January 1, 2017, or any other date. The unaudited pro forma financial results include adjustments for additional amortization expense based on the fair value of the intangible assets with definite lives and their estimated useful lives, as well as changes in depreciation expense associated with the change in fair value of the property, plant and equipment recorded in relation to the acquisition. Interest expense was adjusted to eliminate historical interest associated with QuoteWizard's revolving credit facility and notes payable that were not assumed with the acquisition, as well as reflect incremental interest expense associated with debt issued to finance the acquisition. The provision for income taxes from continuing operations has also been adjusted to reflect taxes on the historical results of operations of QuoteWizard. QuoteWizard did not pay taxes at the entity level as it was a limited liability company whose members elected for it to be taxed as a partnership. 2018 2017 (in thousands) Pro forma revenue $ 900,978 $ 701,184 Pro forma net income from continuing operations $ 110,015 $ 1,164 The unaudited pro forma net income from continuing operations in 2018 includes the aggregate after-tax contingent consideration expense associated with the QuoteWizard earnout of $4.9 million . The unaudited pro forma net income from continuing operations for 2017 has been adjusted to include acquisition-related costs of $5.9 million incurred by the Company and QuoteWizard that are directly attributable to the acquisition, which will not have an ongoing impact. Accordingly, these acquisition-related costs have been eliminated from the unaudited pro forma net income from continuing operations for 2018. Student Loan Hero On July 23, 2018 , the Company acquired Student Loan Hero, Inc., a personal finance website dedicated to helping student loan borrowers manage their student debt. Student Loan Hero offers current and former students in-depth financial comparison tools, educational resources, and unbiased, personalized advice. The Company made an upfront cash payment of $60.7 million at the closing of the transaction, of which $2.3 million was recognized as severance expense in the Company's consolidated statements of operations and comprehensive income. The purchase price of $60.4 million is comprised of the upfront cash payment of $60.7 million less the $2.3 million recognized as severance expense, and a $2.0 million post-closing payment for working capital settlement. The acquisition has been accounted for as a business combination. During 2018, the Company completed the determination of the final allocation of purchase price to the assets acquired and liabilities assumed as follows (in thousands) : Fair Value Net working capital $ 5,429 Intangible assets 19,600 Goodwill 40,856 Deferred tax liabilities (5,467 ) Total purchase price $ 60,418 The Company primarily used the income approach for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions.

The acquired intangible assets are definite-lived assets consisting of content, customer relationships and trademarks and tradenames. The estimated fair values of the content was determined using the excess earnings method, the customer relationships were determined using the distributor method and the trademarks and tradenames were determined using the relief from royalty method. The fair value of the intangible assets with definite lives is as follows (dollars in thousands) : Fair Value Weighted Average Amortization Life Content $ 16,100 3 years Customer lists 2,500 10 years Trademarks and tradenames 1,000 5 years Total intangible assets $ 19,600 4.0 years The Company recorded goodwill of $40.9 million , which represents the excess of the purchase price over the estimated fair value of tangible and intangible assets acquired, net of the liabilities assumed.

For income tax purposes, the acquisition was an equity purchase and the goodwill will not be tax deductible. Acquisition-related costs were $0.5 million in 2018 and are included in general and administrative expense on the consolidated statement of operations and comprehensive income.

These additional payments, to the extent earned, will be payable in cash.

The estimated fair value of the contingent consideration payments is determined using an option pricing model.

Any differences in the actual contingent consideration payments will be recorded in operating income in the consolidated statements of operations and comprehensive income.

The acquired intangible assets are definite-lived assets consisting primarily of developed technology, customer relationships and trade name and trademarks. The estimated fair values of the developed technology were determined using the cost savings method, the customer relationships were determined using the excess earnings method and the trade name and trademarks were determined using the relief from royalty method. The fair value of the intangible assets with definite lives are as follows (dollars in thousands) : Fair Value Weighted Average Amortization Life Technology $ 400 3 years Customer lists 3,300 10 years Trade name and trademarks 600 5 years Total intangible assets $ 4,300 8.7 years The Company recorded goodwill of $13.7 million , which represents the excess of the purchase price over the estimated fair value of the intangible assets acquired. The goodwill is primarily attributable to SnapCap as a going concern which represents the ability of the Company to earn a higher return on the collection of assets and business of SnapCap than if those assets were to be acquired and managed separately. The benefit of access to the workforce is an additional element of goodwill. The goodwill was recorded in the Company’s then one reportable segment. For income tax purposes, the acquisition was an asset purchase and the goodwill will be tax deductible. Acquisition-related costs were $0.3 million in 2017 and are included in general and administrative expense on the consolidated statement of operations and comprehensive income. MagnifyMoney On June 20, 2017 , the Company acquired the membership interests of Camino Del Avion (Delaware), LLC, which does business under the name MagnifyMoney (“MagnifyMoney”) for $29.6 million cash consideration at the closing of the transaction. Camino del Avion (Delaware), LLC was immediately merged with and into LendingTree, LLC following such acquisition. MagnifyMoney is a leading consumer-facing media property that offers editorial content, expert commentary, tools and resources to help consumers compare financial products and make informed financial decisions. The Company also acquired an option to purchase an affiliate in India, which provides technology and research support to MagnifyMoney under a services agreement, for an estimated fair value of $0.5 million at any time during the three years after the closing. This purchase option was exercised on December 31, 2018. In addition, the Company issued two key employees of MagnifyMoney restricted stock unit awards for a total of 38,468 shares of Company common stock. In connection with the terms of the purchase option described above, the Company issued a further restricted stock unit award for 19,234 shares to a key employee of technology and research operations in India upon the exercise of the purchase option. The total value of these restricted stock unit awards was $10.0 million on June 20, 2017. Vesting of these restricted stock units was contingent on the basis of performance conditions following the acquisition. The acquisition has been accounted for as a business combination. During 2017, the Company completed the determination of the final allocation of purchase price to the assets acquired and liabilities assumed as follows (in thousands) : Fair Value Net working capital $ 921 Intangible assets 9,700 Goodwill 23,784 Deferred tax liabilities (4,176 ) Noncontrolling interest (637 ) Total purchase price $ 29,592 The Company primarily used the income approach for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions. Market participants are buyers and sellers unrelated to the Company and fair value is determined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction at the measurement date. The acquired intangible assets are definite-lived assets consisting primarily of content, developed technology, customer relationships and trade name and trademarks. The estimated fair values of the content was determined using the excess earnings method, developed technology was determined using the cost savings method, the customer relationships were determined using the distributor method and the trade name and trademarks were determined using the relief from royalty method. The fair value of the intangible assets with definite lives are as follows (dollars in thousands) : Fair Value Weighted Average Amortization Life Technology $ 200 3 years Customer lists 1,100 9 years Trade name and trademarks 600 4 years Content 7,800 3 years Total intangible assets $ 9,700 3.7 years The Company recorded goodwill of $23.8 million , which represents the excess of the purchase price over the estimated fair value of the tangible and intangible assets acquired, net of the liabilities assumed. The goodwill is primarily attributable to MagnifyMoney as a going concern which represents the ability of the Company to earn a higher return on the collection of assets and business of MagnifyMoney than if those assets were to be acquired and managed separately. The benefit of access to the workforce is an additional element of goodwill. The goodwill was recorded in the Company’s then one reportable segment. For income tax purposes, the acquisition was an equity purchase and the goodwill will not be tax deductible. Acquisition-related costs were $0.4 million in 2017 and are included in general and administrative expense on the consolidated statement of operations and comprehensive income. DepositAccounts On June 14, 2017 , the Company acquired substantially all of the assets of Deposits Online, LLC, which does business under the name DepositAccounts.com (“DepositAccounts”). DepositAccounts is a leading consumer-facing media property in the depository industry and is one of the most comprehensive sources of depository deals and analysis on the Internet, covering all major deposit product categories through editorial content, programmatic rate tables and user-generated content. The Company paid $24.0 million of initial cash consideration and could make additional contingent consideration payments of up to $9.0 million . The potential contingent consideration payments are comprised of (i) up to seven payments of $1.0 million each based on specified increases in Federal Funds interest rates during the period commencing on the closing date and ending on June 30, 2020 and (ii) a one-time performance payment of up to $2.0 million based on the net revenue of deposit products during the period of January 1, 2018 through December 31, 2018. These additional payments, to the extent earned, will be payable in cash. The purchase price for the acquisition is $29.0 million , comprised of the upfront cash payment of $24.0 million and $5.0 million for the estimated fair value of the contingent consideration at the time of closing the acquisition. In the third quarter of 2017, the Company made a payment of $1.0 million associated with a specified increase in the Federal Funds rate in June 2017. In each of the four quarters of 2018, the Company paid $1.0 million associated with specified increases in the Federal Funds rate in December 2017, March 2018, June 2018 and September 2018, respectively, which are included within cash flows from financing activities on the consolidated statement of cash flows, except for an immaterial portion of the fourth quarter payment included within cash flows from operating activities. In the first quarter of 2019, the Company paid $1.0 million associated with a specified increase in the Federal Funds rate in December 2018. In the second quarter of 2019, the Company paid $2.0 million associated with the one-time performance payment based on the net revenue of deposit products during the period of January 1, 2018 through December 31, 2018. The contingent consideration paid in 2019 is included within cash flows from operating activities on the consolidated statement of cash flows. The estimated fair value of the portion of the contingent consideration payments based on increases in interest rates is determined using a scenario approach based on the interest rate forecasts of Federal Open Market Committee participants. The estimated value of the contingent consideration is based upon available information and certain assumptions, known at the time of this report, which management believes are reasonable. Any differences in the actual contingent consideration payments will be recorded in operating income in the consolidated statements of operations and comprehensive income. As of December 31, 2019 , no liability has been recorded in the accompanying consolidated balance sheet for the remaining contingent consideration payment based on Federal Funds interest rates. Accordingly, during 2019 the Company recorded a gain of $1.0 million in the consolidated statement of operations and comprehensive income due to the change in estimated fair value of the contingent consideration. During each of 2018 and 2017, the Company recorded $2.0 million of contingent consideration expense in the consolidated statement of operations and comprehensive income due to the change in estimated fair value of the contingent consideration. The acquisition has been accounted for as a business combination. During 2017, the Company completed the determination of the final allocation of purchase price to the assets acquired and liabilities assumed as follows (in thousands) : Fair Value Intangible assets $ 9,600 Goodwill 19,389 Total purchase price $ 28,989 The Company primarily used the income approach for the valuation as appropriate, and used valuation inputs in these models and analyses that were based on market participant assumptions.

Earnings Per Share [Abstract]
SHAREHOLDERS' EQUITY	SHAREHOLDERS' EQUITY Basic and diluted net income per share was determined based on the following share data (in thousands) : Year Ended December 31, 2019 2018 2017 Weighted average basic common shares 12,834 12,504 11,945 Effect of stock options 747 1,043 1,626 Effect of dilutive share awards 167 153 111 Effect of Convertible Senior Notes and warrants 871 397 — Weighted average diluted common shares 14,619 14,097 13,682 For the years ended December 31, 2019 , 2018 and 2017, the weighted average shares that were anti-dilutive, and therefore excluded from the calculation of diluted income per share, included options to purchase 0.1 million, 0.4 million and 0.1 million shares of common stock, respectively. The 0.625% Convertible Senior Notes due June 1, 2022 and the warrants issued by the Company in 2017 could be converted into the Company’s common stock, subject to certain contingencies. See Note 14 —Debt for additional information. Shares of the Company’s common stock associated with these instruments were excluded from the calculation of diluted income per share during 2017 as they were anti-dilutive since the conversion price of the Convertible Senior Notes and the strike price of the warrants were greater than the average market price of the Company’s common stock. See Note 12 —Stock-Based Compensation for a full description of outstanding equity awards. Common Stock Repurchases In each of February 2018 and February 2019, the board of directors authorized and the Company announced the repurchase of up to $100.0 million and $150.0 million , respectively, of LendingTree's common stock. During the years ended December 31, 2019 , 2018 and 2017 , the Company purchased 22,731 , 379,449 and 75,393 shares, respectively, of its common stock for aggregate consideration of $5.5 million, $92.6 million and $ 21.0 million, respectively. At December 31, 2019 , $ 179.7 million remains authorized for share repurchase.

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION	12 Months Ended

Share-based Payment Arrangement [Abstract]
STOCK-BASED COMPENSATION	STOCK-BASED COMPENSATION The Company currently has two active plans, the Sixth Amended and Restated LendingTree 2008 Stock and Annual Incentive Plan (the "Equity Award Plan") and the LendingTree 2017 Inducement Grant Plan (the "Inducement Plan"), under which future awards may be granted, which currently covers outstanding stock options to acquire shares of the Company's common stock, restricted stock, restricted stock with performance conditions, RSUs and RSUs with performance conditions, and provides for the future grants of these and other equity awards. Under the Equity Award Plan and the Inducement Plan, the Company is authorized to grant stock options, restricted stock, RSUs and other equity-based awards for up to 6.1 million and 0.5 million shares, respectively, of LendingTree common stock to employees, and, under the Equity Award Plan only, to non-employee consultants and directors. The Equity Award Plan and Inducement Plan each have a stated term of ten years and provide that the exercise price of stock options granted will not be less than the market price of the common stock on the grant date. The Equity Award Plan and Inducement Plan do not specify grant dates or vesting schedules, as those determinations are delegated to the Compensation Committee of the board of directors. Each grant agreement reflects the vesting schedule for that particular grant, as determined by the Compensation Committee. The Compensation Committee has the authority to modify the vesting provisions of an award. Non-cash compensation related to equity awards is included in the following line items in the accompanying consolidated statements of operations and comprehensive income (in thousands) : Year Ended December 31, 2019 2019 2018 2017 Cost of revenue $ 755 $ 378 $ 175 Selling and marketing expense 5,785 3,568 3,973 General and administrative expense 39,177 34,325 16,874 Product development 6,450 6,094 2,339 Total non-cash compensation $ 52,167 $ 44,365 $ 23,361 For the years ended December 31, 2019 , 2018 and 2017 , the Company recognized $12.2 million , $11.2 million and $9.5 million of income tax benefit related to non-cash compensation. Additionally, for the years ended December 31, 2019 , 2018 and 2017, the Company recognized $17.1 million , $77.6 million and $12.9 million , respectively, of excess tax benefit, including state taxes, in income tax expense. See Note 2—Significant Accounting Policies, for additional information regarding excess tax benefits and deficiencies. Stock Options A summary of changes in outstanding stock options is as follows: Number of Options Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (a) (per option) (in years) (in thousands) Outstanding at December 31, 2018 940,533 $ 65.12 Granted 43,704 323.82 Exercised (167,686 ) 52.08 Forfeited (38,680 ) 318.36 Expired — — Outstanding at December 31, 2019 777,871 $ 69.87 4.28 $ 182,809 Options exercisable 668,976 $ 39.73 3.61 $ 176,710 (a) The aggregate intrinsic value represents the total pre-tax intrinsic value (the difference between the Company's closing stock price of $303.44 on the last trading day of 2019 and the exercise price, multiplied by the number of shares covered by in-the-money options) that would have been received by the option holder had the option holder exercised these options on December 31, 2019 . The intrinsic value changes based on the market value of the Company's common stock. As of December 31, 2019 , there was approximately $10.5 million of unrecognized compensation cost related to stock options. These costs are expected to be recognized over a weighted-average period of approximately 2.2 years . Upon exercise, the intrinsic value represents the pre-tax difference between the Company's closing stock price on the exercise date and the exercise price, multiplied by the number of stock options exercised. During the years ended December 31, 2019 , 2018 and 2017 , the total intrinsic value of stock options that were exercised was $50.2 million , $268.3 million and $27.7 million , respectively. Cash received from stock option exercises and the related actual tax benefit realized were $8.7 million and $11.9 million , respectively, for the year ended December 31, 2019 . During the years ended December 31, 2019 , 2018 and 2017 , the Company granted stock options with a weighted average grant date fair value per share of $167.10 , $150.55 and $105.15 , respectively, of which the vesting periods include (a) immediately upon grant, (b) one year from the grant date, (c) 50% over a period of two years from the grant date, (d) 33% over a period of three years from the grant date, and (e) certain grants to executive officers that vest over periods of up to five and a half years. For purposes of determining stock-based compensation expense, the weighted average grant date fair value per share of the stock options was estimated using the Black-Scholes option pricing model, which requires the use of various key assumptions. The weighted average assumptions used are as follows: Year Ended December 31, 2019 2018 2017 Expected term (1) 5.00 - 6.25 years 5.00 - 6.71 years 5.00 - 7.00 years Expected dividend (2) — — — Expected volatility (3) 51% - 55% 50% - 53% 51% - 52% Risk-free interest rate (4) 1.46% - 2.55 % 2.33% - 3.06% 1.74% - 2.24% (1) The expected term of stock options granted was calculated using the 'Simplified Method', which utilizes the midpoint between the weighted average time of vesting and the end of the contractual term. This method was utilized for the stock options due to a lack of historical exercise behavior by the Company's employees. (2) For all stock options granted during the years ended December 31, 2019 , 2018 and 2017 , no dividends are expected to be paid over the contractual term of the stock options, resulting in a zero expected dividend rate. (3) The expected volatility rate is based on the historical volatility of the Company's common stock. (4) The risk-free interest rate is specific to the date of grant. The risk-free interest rate is based on U.S. Treasury yields for notes with comparable expected terms as the awards, in effect at the grant date. During the years ended December 31, 2019 , 2018 and 2017 , the total fair value of options vested was $6.9 million , $11.4 million and $4.1 million , respectively. Stock Options with Performance Conditions A summary of changes in outstanding stock options with performance conditions is as follows: Number of Options with Performance Conditions Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (per option) (in years) (in thousands) Outstanding at December 31, 2018 37,877 $ 308.90 Granted — — Exercised — — Forfeited — — Expired (37,877 ) 308.90 Outstanding at December 31, 2019 — $ — 0.00 $ — Options exercisable — $ — 0.00 $ — No stock options with performance conditions were granted in 2019 or 2018. During 2017, the Company granted stock options with performance conditions with a weighted average grant date fair value per share of $152.45 , of which vesting periods range from 1.2 years to 2.2 years , pending the attainment of certain performance targets set at the time of grant. The performance measurement period ended on December 31, 2019. The performance conditions associated with this grant were not met, and the performance-based nonqualified stock options were not earned. No compensation cost associated with these options has been recorded. For purposes of determining stock-based compensation expense, the weighted average grant date fair value per share of the stock options was estimated using the Black-Scholes option pricing model, which requires the use of various key assumptions. The weighted average assumptions used are as follows: Year ended December 31, 2017 Expected term (1) 5.50 - 6.00 years Expected dividend (2) — Expected volatility (3) 51% Risk-free interest rate (4) 2.16% - 2.23% (1) The expected term of stock options granted was calculated using the 'Simplified Method', which utilizes the midpoint between the weighted average time of vesting and the end of the contractual term. This method was utilized for the stock options due to a lack of historical exercise behavior by the Company's employees. (2) For all stock options granted during the year ended December 31, 2017, no dividends are expected to be paid over the contractual term of the stock options, resulting in a zero expected dividend rate. (3) The expected volatility rate is based on the historical volatility of the Company's common stock. (4) The risk-free interest rate is specific to the date of grant. The risk-free interest rate is based on U.S. Treasury yields for notes with comparable expected terms as the awards, in effect at the grant date. Stock Options with Market Conditions A summary of changes in outstanding stock options with market conditions at target is as follows: Number of Options with Market Conditions Weighted Average Exercise Price Weighted Average Remaining Contractual Term Aggregate Intrinsic Value (a) (per option) (in years) (in thousands) Outstanding at December 31, 2018 447,193 $ 200.51 Granted 16,247 308.96 Exercised — — Forfeited — — Expired — — Outstanding at December 31, 2019 463,440 $ 204.31 7.67 $ 48,178 Options exercisable — $ — 0.00 $ — (a) The aggregate intrinsic value represents the total pre-tax intrinsic value (the difference between the Company's closing stock price of $303.44 on the last trading day of 2019 and the exercise price, multiplied by the number of shares covered by in-the-money options) that would have been received by the option holder had the option holder exercised these options on December 31, 2019 . The intrinsic value changes based on the market value of the Company's common stock. As of December 31, 2019 , there was approximately $40.5 million of unrecognized compensation cost related to stock options with market conditions. These costs are expected to be recognized over a weighted-average period of approximately 2.8 years . The fair value of the stock options with market conditions will be recognized on a straight-line basis through each grant’s vest date, whether or not any of the total shareholder return targets are met. During the years ended December 31, 2019 , 2018 and 2017 , the Company granted stock options with a weighted-average grant date fair value per share of $230.81 , $296.80 and $142.45 , respectively, which have vest dates of March 31, 2023, March 31, 2022 and September 30, 2022, respectively. For purposes of determining stock-based compensation expense, the weighted-average grant date fair value per share of the stock options with a market condition was estimated using the Monte Carlo simulation model, which requires the use of various key assumptions. The weighted-average assumptions used are as follows: Year Ended December 31, 2019 2018 2017 Expected term (1) 7.00 years 7.00 - 7.15 years 7.50 years Expected dividend (2) — — — Expected volatility (3) 51% 50% 50% Risk-free interest rate (4) 2.54% 2.38% - 2.81% 2.12% (1) The expected term of stock options with a market condition granted was calculated using the midpoint between the weighted average time of vesting and the end of the contractual term. (2) For all stock options with a market condition granted during the years ended December 31, 2019 , 2018 and 2017 , no dividends are expected to be paid over the contractual term of the stock options, resulting in a zero expected dividend rate. (3) The expected volatility rate is based on the historical volatility of the Company's common stock. (4) The risk-free interest rate is specific to the date of grant. The risk-free interest rate is based on U.S. Treasury yields for notes with comparable expected terms as the awards, in effect at the grant date. The stock options with a market condition granted in 2019 have a target number of shares that vest upon achieving a targeted total shareholder return performance of 81% stock price appreciation and a maximum of 27,132 shares for achieving superior performance. No shares will vest unless 41% of the targeted performance is achieved. The performance measurement period ends on March 31, 2023. Certain of the stock options with a market condition granted in 2018 have a target number of shares that vest upon achieving a targeted total shareholder return performance of 110% stock price appreciation and a maximum of 52,332 shares for achieving superior performance.

The expense is primarily related to the remeasurement of LendingTree’s deferred tax assets and liabilities considering the TCJA’s enacted tax rates and certain other impacts. Simultaneous with the Act, the SEC Staff released Accounting Bulletin No. 118 ("SAB 118"), which allows the use of provisional amounts (reasonable estimates) if the analysis of the impacts of the Act have not been completed when financial statements are issued. During the fourth quarter of 2018, the Company finalized the computations of the income tax effects of the Act. As such, in accordance with SAB 118, the Company's accounting for the effects of the Act is complete. The Company did not significantly adjust provisional amounts recorded in 2017 and the SAB 118 measurement period subsequently ended on December 22, 2018. Although the Company no longer considers these amounts to be provisional, the determination of the Act’s income tax effects may change following future legislation or further interpretation of the Act based on the publication of recently proposed U.S. Treasury regulations and guidance from the Internal Revenue Service and state tax authorities. Deferred Income Taxes The tax effects of cumulative temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities are as follows (in thousands) : December 31, 2019 2018 Deferred tax assets: Provision for accrued expenses $ 12,234 $ 5,953 Leasing (a) 7,299 — Net operating loss carryforwards (b) 56,450 59,817 Non-cash compensation expense 15,805 12,505 Interest limitation 987 3,532 Contingent liabilities 9,366 3,053 Tax credits 6,124 1,569 Other 1,624 2,976 Total gross deferred tax assets 109,889 89,405 Less: valuation allowance (c) (4,102 ) (2,229 ) Total deferred tax assets, net of the valuation allowance 105,787 87,176 Deferred tax liabilities: Intangible and other assets (1,744 ) (4,623 ) Leasing (a) (6,596 ) — Other (1,835 ) (892 ) Total gross deferred tax liabilities (10,175 ) (5,515 ) Net deferred taxes $ 95,612 $ 81,661 (a) As of December 31, 2019, the adoption of ASC Topic 842 has no material impact to the effective tax rate. Related deferred tax positions are individually disclosed as components of deferred tax as of December 31, 2019. (b) At December 31, 2019 , the Company had pre-tax consolidated federal net operating losses ("NOLs") of $188.2 million . The federal NOLs no longer expire under the new TCJA. The Company's NOLs will be available to offset taxable income subject to the Internal Revenue Code Section 382 annual limitation. In addition, the Company has state NOLs of approximately $484.7 million at December 31, 2019 that will expire at various times between 2021 and 2039. (c) The valuation allowance is related to items for which it is "more likely than not" that the tax benefit will not be realized. Deferred income taxes are presented in the accompanying consolidated balance sheets as follows (in thousands) : December 31, 2019 2018 Deferred income tax assets $ 87,664 $ 79,289 Non-current assets of discontinued operations 7,948 3,266 Deferred income tax liabilities — (894 ) Net deferred taxes $ 95,612 $ 81,661 Valuation Allowance A valuation allowance is provided on deferred tax assets if it is determined that it is "more likely than not" that the deferred tax asset will not be realized. As of each reporting date, management considers both positive and negative evidence regarding the likelihood of future realization of the deferred tax assets. At December 31, 2019 , 2018 and 2017 , the Company recorded a partial valuation allowance of $4.1 million , $2.2 million and $2.7 million , respectively, primarily related to state net operating losses, which the Company does not expect to be able to utilize prior to expiration. A reconciliation of the beginning and ending balances of the deferred tax valuation allowance is as follows (in thousands) : Year Ended December 31, 2019 2018 2017 Balance, beginning of the period $ 2,229 $ 2,694 $ 2,101 Charges to earnings 1,873 (465 ) 593 Balance, end of the period $ 4,102 $ 2,229 $ 2,694 Unrecognized Tax Benefits A reconciliation of the beginning and ending amounts of unrecognized tax benefits, excluding interest and penalties, is as follows (in thousands) : Year Ended December 31, 2019 2018 Balance, beginning of the period $ 1,127 $ 748 Additions based on tax positions of the current period 525 249 Additions based on tax positions of the prior period 344 130 Balance, end of the period $ 1,996 $ 1,127 Interest and, if applicable, penalties are recognized related to unrecognized tax benefits in income tax expense. Interest and penalties on unrecognized tax benefits included in income tax expense for each of the years ended December 31, 2019 , 2018 and 2017 is immaterial. As of December 31, 2019 and 2018 , the accrual for unrecognized tax benefits, including interest, was $2.1 million and $1.2 million , respectively, which would benefit the effective tax rate if recognized. Management also believes that it is reasonably possible that the amount of unrecognized income tax benefits may decrease by $0.6 million within the next twelve months due to settlement of audits and expiration of statutes of limitations. Tax Audits LendingTree is subject to audits by federal, state and local authorities in the area of income tax. These audits include questioning the timing and the amount of deductions and the allocation of income among various tax jurisdictions. Income taxes payable include amounts considered sufficient to pay assessments that may result from examination of prior year returns; however, any amounts paid upon resolution of issues raised may differ from the amount provided. Differences between the reserves for tax contingencies and the amounts owed by the Company are recorded in the period they become known. As of December 31, 2019 , the Company is subject to a federal income tax examination for the tax years 2014 through 2018. In addition, the Company is subject to state and local tax examinations for the tax years 2014 through 2018.

DEBT DEBT

DEBT DEBT	12 Months Ended

Debt Disclosure [Abstract]
DEBT	DEBT Convertible Senior Notes On May 31, 2017, the Company issued $300.0 million aggregate principal amount of its 0.625% Convertible Senior Notes due June 1, 2022 (the “Notes”) in a private placement. The Notes bear interest at a rate of 0.625% per year, payable semi-annually on June 1 and December 1 of each year, beginning on December 1, 2017. The Notes will mature on June 1, 2022, unless earlier repurchased or converted. The initial conversion rate of the Notes is 4.8163 shares of Common Stock per $1,000 principal amount of Notes (which is equivalent to an initial conversion price of approximately $207.63 per share). The conversion rate will be subject to adjustment upon the occurrence of certain specified events but will not be adjusted for accrued and unpaid interest. In addition, upon the occurrence of a fundamental change prior to the maturity of the Notes, the Company will, in certain circumstances, increase the conversion rate by a specified number of additional shares for a holder that elects to convert the Notes in connection with such fundamental change. Upon conversion, the Notes will settle for cash, shares of the Company’s stock, or a combination thereof, at the Company’s option. It is the intent of the Company to settle the principal amount of the Notes in cash and any conversion premium in shares of its common stock. The Notes are the Company’s senior unsecured obligations and will rank senior in right of payment to any of the Company’s indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to any of the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s secured indebtedness, including borrowings under the senior secured revolving credit facility, described below, to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of the Company’s subsidiaries. Prior to the close of business on the business day immediately preceding February 1, 2022, the Notes will be convertible at the option of the holders thereof only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ending on September 30, 2017 (and only during such calendar quarter), if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during the 30 consecutive trading day period ending on, and including the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; • during the five business day period after any five consecutive trading day period in which, for each trading day of that period, the trading price (as defined in the Notes) per $1,000 principal amount of Notes for such trading day was less than 98% of the product of the last reported sale price of the Common Stock and the conversion rate on each such trading day; or • upon the occurrence of specified corporate events including but not limited to a fundamental change. Holders of the Notes became entitled to convert the Notes on January 1, 2018, based on the last reported sales price of the Company's common stock, for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on December 31, 2017, being greater than or equal to 130% of the conversion price of the Notes on each applicable trading day. Holders of the Notes continued to have such right until June 30, 2018 based on the last reported sales price of the Company's common stock, for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on March 31, 2018, being greater than or equal to 130% of the conversion price of the Notes on each applicable trading day. Holders of the Notes were not entitled to convert the Notes from July 1, 2018 to March 31, 2019. Holders of the Notes became entitled to convert the Notes on April 1, 2019, based on the last reported sales price of the Company's common stock, for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on March 31, 2019, being greater than or equal to 130% of the conversion price of the Notes on each applicable trading day. Holders of the Notes will continue to have such right until March 31, 2020, based on the last reported sales price of the Company's common stock, for at least 20 trading days (whether or not consecutive) during the period of 30 consecutive trading days ending on December 31, 2019, being greater than or equal to 130% of the conversion price of the Notes on each applicable trading day. On or after February 1, 2022, until the close of business on the second scheduled trading day immediately preceding the maturity date of the Notes, holders of the Notes may convert all or a portion of their Notes regardless of the foregoing conditions. The Company may not redeem the Notes prior to the maturity date and no sinking fund is provided for the Notes. Upon the occurrence of a fundamental change prior to the maturity date of the Notes, holders of the Notes may require the Company to repurchase all or a portion of the Notes for cash at a price equal to 100% of the principal amount of the Notes to be repurchased, plus any accrued and unpaid interest to, but excluding, the fundamental change repurchase date. If the market price per share of the Common Stock, as measured under the terms of the Notes, exceeds the conversion price of the Notes, the Notes could have a dilutive effect, unless the Company elects, subject to certain conditions, to settle the principal amount of the Notes and any conversion premium in cash. The initial measurement of convertible debt instruments that may be settled in cash is separated into a debt and an equity component whereby the debt component is based on the fair value of a similar instrument that does not contain an equity conversion option. The separate components of debt and equity of the Company’s Notes were determined using an interest rate of 5.36% , which reflects the nonconvertible debt borrowing rate of the Company at the date of issuance. As a result, the initial components of debt and equity were $238.4 million and $61.6 million , respectively. Financing costs related to the issuance of the Notes were approximately $9.3 million of which $7.4 million were allocated to the liability component and are being amortized to interest expense over the term of the debt and $1.9 million were allocated to the equity component. During 2019 , the Company recorded interest expense on the Notes of $15.3 million which consisted of $1.9 million associated with the 0.625% coupon rate, $12.0 million associated with the accretion of the debt discount, and $1.4 million associated with the amortization of the debt issuance costs. During 2018 , the Company recorded interest expense on the Notes of $14.6 million which consisted of $1.9 million associated with the 0.625% coupon rate, $11.4 million associated with the accretion of the debt discount, and $1.3 million associated with the amortization of the debt issuance costs. During 2017, the Company recorded interest expense on the Notes of $8.2 million which consisted of $1.1 million associated with the 0.625% coupon rate, $6.4 million associated with the accretion of the debt discount, and $0.7 million associated with the amortization of the debt issuance costs. The debt discount is being amortized over the term of the debt. As of December 31, 2019 , the fair value of the Notes is estimated to be approximately $469.1 million using the Level 1 observable input of the last quoted market price on December 31, 2019 . A summary of the gross carrying amount, unamortized debt cost, debt issuance costs and net carrying value of the liability component of the Notes are as follows (in thousands) : December 31, December 31, Gross carrying amount $ 299,991 $ 300,000 Unamortized debt discount 31,789 43,805 Debt issuance costs 3,811 5,252 Net carrying amount $ 264,391 $ 250,943 Convertible Note Hedge and Warrant Transactions On May 31, 2017, in connection with the issuance of the Notes, the Company entered into Convertible Note Hedge (the “Hedge”) and Warrant transactions with respect to the Company’s common stock. The Company used approximately $18.1 million of the net proceeds from the Notes to pay for the cost of the Hedge, after such cost was partially offset by the proceeds from the Warrant transactions. On May 31, 2017, the Company paid $61.5 million to the counterparties for the Hedge transactions. The Hedge transactions cover approximately 1.4 million shares of the Company’s common stock, the same number of shares initially underlying the Notes, and are exercisable upon any conversion of the Notes. The Hedge Transactions are expected generally to reduce the potential dilution to the Common Stock upon conversion of the Notes and/or offset any cash payments the Company is required to make in excess of the principal amount of the converted Notes, as the case may be, in the event that the market price per share of Common Stock, as measured under the terms of the Hedge transactions, is greater than the strike price of the Hedge transactions, which initially corresponds to the initial conversion price of the Notes, or approximately $207.63 per share of Common Stock. The Hedge transactions will expire upon the maturity of the Notes. On May 31, 2017, the Company sold to the counterparties, warrants (the "Warrants") to acquire 1.4 million shares of Common Stock at an initial strike price of $266.39 per share, which represents a premium of 70% over the reported sale price of the Common Stock of $156.70 on May 24, 2017. On May 31, 2017, the Company received aggregate proceeds of approximately $43.4 million from the sale of the Warrants. If the market price per share of the Common Stock, as measured under the terms of the Warrants, exceeds the strike price of the Warrants, the Warrants could have a dilutive effect, unless the Company elects, subject to certain conditions, to settle the Warrants in cash. The Hedge and Warrant transactions are indexed to, and potentially settled in, the Company's common stock and the net cost of $18.1 million has been recorded as a reduction to additional paid-in capital in the consolidated statement of shareholders’ equity. Senior Secured Revolving Credit Facility On December 10, 2019 , the Company's wholly-owned subsidiary, LendingTree, LLC, entered into an amended and restated $500.0 million five -year senior secured revolving credit facility (the “Amended Revolving Credit Facility”), which amended and restated the Company's previous $350.0 million five-year senior secured revolving credit facility (the “2017 Revolving Credit Facility”). The Amended Revolving Credit Facility matures on December 10, 2024 . Borrowings under the Amended Revolving Credit Facility can be used to finance working capital needs, capital expenditures and general corporate purposes, including to finance permitted acquisitions. As of December 31, 2019 , the Company had $75.0 million in borrowings outstanding under the Amended Revolving Credit Facility at the LIBO rate option with a weighted average interest rate of 3.01% , consisting of a $50.0 million 31-day borrowing and a $25.0 million 31-day borrowing. As of December 31, 2018, the Company had a $125.0 million , 31-day borrowing outstanding under the Revolving Credit Facility bearing interest at the LIBO rate option of 4.02% . Up to $10.0 million of the Amended Revolving Credit Facility will be available for short-term loans, referred to as swingline loans. Under certain conditions, the Company will be permitted to add one or more term loans and/or increase revolving commitments under the Amended Revolving Credit Facility by an additional amount equal to the greater of $185.0 million or 100% of Consolidated EBITDA as defined, or a greater amount provided that a total consolidated senior secured debt to EBITDA ratio does not exceed 2.50 to 1.00 . Additionally, up to $10.0 million of the Amended Revolving Credit Facility will be available for the issuance of letters of credit. As of December 31, 2019, the Company has outstanding one letter of credit issued in the amount of $0.2 million . The Company’s borrowings under the Amended Revolving Credit Facility bear interest at annual rates that, at the Company’s option, will be either: • a base rate generally defined as the sum of (i) the greater of (a) the prime rate of Truist Bank, (b) the federal funds effective rate plus 0.5% and (c) the LIBO rate (defined below) on a daily basis applicable for an interest period of one month plus 1.0% and (ii) an applicable percentage of 0.25% to 1.0% based on a total consolidated debt to EBITDA ratio; or • a LIBO rate generally defined as the sum of (i) the rate for Eurodollar deposits in the applicable currency and (ii) an applicable percentage of 1.25% to 2.0% based on a total consolidated debt to EBITDA ratio. All swingline loans bear interest at the base rate defined above. Interest on the Company’s borrowings are payable quarterly in arrears for base rate loans and on the last day of each interest rate period (but not less often than three months) for LIBO rate loans. The Amended Revolving Credit Facility contains a restrictive financial covenant, which initially limits the total consolidated debt to EBITDA ratio to 4.5 , with step downs to 4.0 over time, except that this may increase by 0.5 for the four fiscal quarters following a material acquisition. In addition, the Amended Revolving Credit Facility contains customary affirmative and negative covenants in addition to events of default for a transaction of this type that, among other things, restrict additional indebtedness, liens, mergers or certain fundamental changes, asset dispositions, dividends, stock repurchases and other restricted payments, transactions with affiliates, sale-leaseback transactions, hedging transactions, loans and investments and other matters customarily restricted in such agreements. The Company was in compliance with all covenants at December 31, 2019 . The Amended Revolving Credit Facility requires LendingTree, LLC to pledge as collateral, subject to certain customary exclusions, substantially all of its assets, including 100% of its equity in all of its domestic subsidiaries and 66% of the voting equity, and 100% of the non-voting equity, in all of its material foreign subsidiaries (of which there are currently none). The obligations under this facility are unconditionally guaranteed on a senior basis by LendingTree, Inc. and material domestic subsidiaries of LendingTree, LLC, which guaranties are secured by a pledge as collateral, subject to certain customary exclusions, of 100% of each such guarantor's assets, including 100% of each such guarantor’s equity in all of its domestic subsidiaries and 66% of the voting equity, and 100% of the non-voting equity, in all of its material foreign subsidiaries (of which there are currently none). The Company is required to pay an unused commitment fee quarterly in arrears on the difference between committed amounts and amounts actually borrowed under the Amended Revolving Credit Facility equal to an applicable percentage of 0.25% to 0.45% per annum based on a total consolidated debt to EBITDA ratio. The Company is required to pay a letter of credit participation fee and a letter of credit fronting fee quarterly in arrears. The letter of credit participation fee is based upon the aggregate face amount of outstanding letters of credit at an applicable percentage of 1.25% to 2.0% based on a total consolidated debt to EBITDA ratio. The letter of credit fronting fee is 0.125% per annum on the face amount of each letter of credit. The Company recognized $0.3 million and $0.1 million in additional interest expense in the fourth quarters of 2019 and 2017, respectively, due to the write-off of certain unamortized debt issuance costs associated with the original revolving credit facility and previous amendments to the credit agreement. In addition to the remaining unamortized debt issuance costs associated with the original revolving credit facility and the Revolving Credit Facility, debt issuance costs of $2.8 million related to the Amended Revolving Credit Facility entered into on December 10, 2019 are being amortized to interest expense over the life of the Amended Revolving Credit Facility, and are included in prepaid and other current assets and other non-current assets in the Company's consolidated balance sheet. During 2019 , the Company recorded interest expense related to the revolving credit facility of $6.1 million which consisted of $4.9 million associated with borrowings bearing interest at the LIBO rate, $0.6 million in unused commitment fees, and $0.6 million associated with the amortization of the debt issuance costs. During 2018 , the Company recorded interest expense related to the revolving credit facility of $2.0 million which consisted of $0.8 million associated with borrowing bearing interest at the base rate and the LIBO rate, $0.8 million in unused commitment fees, and $0.4 million associated with the amortization of the debt issuance costs. During 2017 , the Company recorded interest expense related to the revolving credit facility of $0.5 million in unused commitment fees and $0.4 million associated with the amortization of the debt issuance costs.

Commitments and Contingencies Disclosure [Abstract]
CONTINGENCIES	CONTINGENCIES Overview LendingTree is involved in legal proceedings on an ongoing basis. In assessing the materiality of a legal proceeding, the Company evaluates, among other factors, the amount of monetary damages claimed, as well as the potential impact of non-monetary remedies sought by plaintiffs (e.g., injunctive relief) that may require it to change its business practices in a manner that could have a material and adverse impact on the Company's business. With respect to the matters disclosed in this Note 16 , unless otherwise indicated, the Company is unable to estimate the possible loss or range of losses that could potentially result from the application of such non-monetary remedies. As of December 31, 2019 , the Company had litigation settlement accruals of $0.2 million and $31.0 million in continuing operations and discontinued operations, respectively. As of December 31, 2018 , the Company had litigation settlement accruals of $0.2 million and $8.0 million in continuing operations and discontinued operations, respectively. The litigation settlement accruals relate to litigation matters that were either settled or a firm offer for settlement was extended, thereby establishing an accrual amount that is both probable and reasonably estimable. See Note 20 —Discontinued Operations for additional information.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENTS Other than the Notes and the Warrants, the carrying amounts of the Company's financial instruments are equal to fair value at December 31, 2019 . See Note 14 —Debt for additional information on the Notes and the Warrants. Contingent consideration payments related to acquisitions are measured at fair value each reporting period using Level 3 unobservable inputs. The changes in the fair value of the Company's Level 3 liabilities during the years ended December 31, 2019 , 2018 and 2017 are as follows (in thousands) : Year Ended December 31, 2019 2018 2017 Contingent consideration, beginning of period $ 38,837 $ 57,349 $ 23,100 Transfers into Level 3 — — — Transfers out of Level 3 — — — Total net losses included in earnings (realized and unrealized) 28,402 10,788 23,931 Purchases, sales and settlements: Additions — 19,700 11,318 Payments (33,775 ) (49,000 ) (1,000 ) Contingent consideration, end of period $ 33,464 $ 38,837 $ 57,349 The contingent consideration liability at December 31, 2019 and 2018 consisted of the estimated fair value of the earnout payments of the DepositAccounts, SnapCap, Ovation, and QuoteWizard acquisitions. The contingent consideration liability at December 31, 2017 was the estimated fair value of the earnout payments of the CompareCards, DepositAccounts, and SnapCap acquisitions. The Company will make earnout payments ranging from zero to $1.0 million based on the achievement of defined milestone targets for DepositAccounts, payments ranging from $3.0 million to $6.0 million based on the achievement of certain defined earnings targets for SnapCap, payments ranging from zero to $4.4 million based on the achievement of certain defined operating metrics for Ovation, and payments ranging from zero to $46.8 million based on the achievement of certain defined performance targets for QuoteWizard. See Note 8 —Business Acquisitions for additional information on the contingent consideration for each of these respective acquisitions. The significant unobservable inputs used to calculate the fair value of the contingent consideration are estimated future cash flows for the acquisitions, estimated customer growth rates, estimated date and likelihood of an increase in interest rates and the discount rate. Actual results will differ from the projected results and could have a significant impact on the estimated fair value of the contingent considerations. Additionally, as the liability is stated at present value, the passage of time alone will increase the estimated fair value of the liability each reporting period. Any changes in fair value will be recorded in operating income in the consolidated statements of operations and comprehensive income.

Discontinued Operations and Disposal Groups [Abstract]
DISCONTINUED OPERATIONS	ASSETS HELD FOR SALE In December 2016, the Company acquired two office buildings in Charlotte, North Carolina for $23.5 million in cash, which included $0.1 million in acquisition-related costs which were capitalized. The buildings were acquired with the intent to use such buildings as the Company's corporate headquarters and rent any unused space. In November 2018, the Company's Board of Directors approved a plan to sell the two office buildings. The properties were classified as current assets held for sale in the consolidated balance sheet for December 31, 2018. The Company sold these buildings to an unrelated third party in the second quarter of 2019 for a sale price of $24.4 million , and the Company incurred closing fees of $0.3 million . The Company recognized a gain of $2.7 million on the sale within general and administrative expense in the consolidated statement of operations and comprehensive income. At the time the buildings were classified as held for sale, and at time of sale, they were associated with the Company's then one reportable segment. Property and equipment classified as held for sale at December 31, 2018 is as follows (in thousands) : Amount Land $ 5,818 Building 14,984 Site improvements 950 Computer equipment and capitalized software 166 Furniture and other equipment 145 Total gross property and equipment 22,063 Accumulated depreciation (1,278 ) Total property and equipment, net $ 20,785 Intangible assets classified as held for sale at December 31, 2018 is as follows (in thousands) : Amount Tenant leases $ 961 Total gross intangible assets 961 Accumulated amortization (468 ) Total intangible assets, net $ 493 The LendingTree Loans Business is presented as discontinued operations in the accompanying financial statements. The LendingTree Loans Business originated various consumer mortgage loans through HLC. On June 6, 2012, the Company sold substantially all of the operating assets of HLC, including the LendingTree Loans Business, for $55.9 million in cash to a wholly-owned subsidiary of Discover Financial Services ("Discover"). Discover generally did not assume liabilities of HLC that arose before the closing date, except for certain liabilities directly related to assets Discover acquired. Of the purchase price received, a portion was deposited in escrow in accordance with the purchase agreement with Discover for certain loan loss obligations that remained with HLC following the sale. During 2018, the remaining funds in escrow were released to HLC in accordance with the terms of the purchase agreement with Discover. Upon closing of the sale of substantially all of the operating assets of HLC on June 6, 2012, HLC ceased to originate consumer loans. Liability for losses on previously sold loans remains with HLC and is discussed below. Litigation settlements and contingencies and legal fees associated with ongoing related bankruptcy and legal proceedings against the Company are included in discontinued operations in the accompanying financial statements. Home Loan Center, Inc. Bankruptcy Filing On June 21, 2019, the U.S. District Court of Minnesota entered judgment in ResCap Liquidating Trust v. Home Loan Center, Inc. , against HLC for $68.5 million , see Litigation Related to Discontinued Operations below. The judgment against HLC exceeded the assets of HLC, which were $11.2 million at July 21, 2019, including cash of $5.9 million . On July 19, 2019, HLC appealed the judgment to the United States Court of Appeals for the Eighth Circuit. On July 21, 2019, at the direction of the sole independent director of HLC, HLC voluntarily filed a petition under Chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) with the U.S. Bankruptcy Court in the Northern District of California in San Jose, California (the “Bankruptcy Court”) in order to preserve assets for the benefit of all creditors of HLC. On September 16, 2019, the Bankruptcy Court converted the bankruptcy to Chapter 7 of the Bankruptcy Code and appointed a Trustee to liquidate HLC’s assets. HLC’s filing under the Bankruptcy Code creates an automatic stay of enforcement of the judgment entered against HLC by the Minnesota court in ResCap Liquidating Trust v. Home Loan Center, Inc. described above and in Litigation Related to Discontinued Operations below. As a result of the voluntary petition, LendingTree, LLC was, as of the initial July 21, 2019 bankruptcy petition filing date, no longer deemed to have a controlling interest in HLC under applicable accounting standards. As a result, HLC and its consolidated subsidiary were deconsolidated from the Company’s consolidated financial statements as of July 21, 2019. The effect of such deconsolidation was the elimination of the consolidated assets and liabilities of HLC (and its consolidated subsidiary) from the Company’s consolidated balance sheets. Upon deconsolidation, in 2019 the Company recognized a loss of $5.5 million which includes a net gain of $4.5 million related to the removal of HLC's (and its consolidated subsidiary's) assets and liabilities and the recognition of a liability of $10.0 million related to LendingTree LLC's ownership in HLC. No consideration was received by the Company as a result of the deconsolidation. The derecognition of HLC’s cash of $5.9 million removed from the consolidated balance sheet on the deconsolidation date of July 21, 2019 is included within cash flows from operating activities attributable to discontinued operations in the accompanying consolidated statement of cash flows. HLC has indicated that it believes that it has claims against HLC’s sole shareholder, LendingTree, LLC, and certain of its officers and directors, relating to the declaration of a dividend by HLC in January 2016 of $40.0 million . The Company is obligated to advance any expenses to the officers and directors related to these claims and to indemnify them to the maximum extent permitted by law. LendingTree, LLC believes the declaration of the dividend was proper, that the amounts paid to LendingTree, LLC following such declaration are not subject to recovery by HLC and that any claims by HLC relating to such dividend declaration are without merit. LendingTree, LLC intends to vigorously contest such claims. During the third quarter of 2019, LendingTree, LLC made a settlement offer to HLC after it filed for bankruptcy for $31.0 million for the release of any and all claims against the Company, including the dividend claim. LendingTree estimates the range of potential losses related to the dividend matter to be $0.0 million to $40.0 million plus a potential award of prejudgment interest. An estimated liability of $31.0 million is included in the accompanying consolidated balance sheet as of December 31, 2019 related to LendingTree LLC's ownership in HLC. HLC’s voluntary petition under the Bankruptcy Code does not represent an event of default under LendingTree, LLC’s Second Amended and Restated Credit Agreement dated as of December 10, 2019 or the Company’s indenture dated May 31, 2017 with respect to the Company’s 0.625% Convertible Senior Notes due 2022. Loan Loss Obligations Prior to the sale of its LendingTree Loans Business on June 6, 2012, HLC sold loans it originated through its LendingTree Loans Business to investors on a servicing-released basis, so the risk of loss or default by the borrower was generally transferred to the investor. However, HLC was required by these investors to make certain representations and warranties relating to credit information, loan documentation and collateral. These representations and warranties may extend through the contractual life of the loan. If underwriting deficiencies, borrower fraud or documentation defects, arising prior to the sale of the loan by HLC to such investor, are discovered in individual loans, HLC may be obligated to repurchase the respective loan or indemnify such investor for any losses from borrower defaults if such deficiency or defect cannot be cured within the contractually specified period following discovery. HLC continues to be liable for these indemnification obligations, repurchase obligations and premium repayment obligations following the sale of substantially all of its operating assets, including the LendingTree Loans Business, in the second quarter of 2012. The liability for losses on previously sold loans was presented as current liabilities of discontinued operations in the accompanying consolidated balance sheet as of December 31, 2018. Additionally, LendingTree guaranteed certain loans sold to investors in the event that HLC is unable to satisfy its repurchase and warranty obligations related to such loans. Litigation Related to Discontinued Operations Residential Funding Company ResCap Liquidating Trust v. Home Loan Center, Inc., Case No. 14-cv-1716 (U.S. Dist. Ct., Minn.), successor to Residential Funding Company, LLC v Home Loan Center, Inc., No. 13-cv-3451 (U.S. Dist. Ct., Minn.). On or about December 16, 2013, Home Loan Center, Inc. was served in the original captioned matter, which involves claims of Residential Funding Company, LLC ("RFC") for damages for breach of contract and indemnification for certain residential mortgage loans as well as residential mortgage-backed securitizations ("RMBS") containing mortgage loans. RFC asserted that, beginning in 2008, RFC faced massive repurchase demands and lawsuits from purchasers or insurers of the loans and RMBS that RFC had sold. RFC filed for bankruptcy protection in May 2012. Plaintiff alleged that, after RFC filed for Chapter 11 protection, hundreds of proofs of claim were filed, many of which mirrored the litigation filed against RFC prior to its bankruptcy. In December 2013, the United States Bankruptcy Court for the Southern District of New York entered an Order confirming the Second Amended Joint Chapter 11 Plan Proposed by Residential Capital, LLC et al. and the Official Committee of Unsecured Creditors. Plaintiff then began filing substantially similar complaints against approximately 80 of the loan originators from whom RFC had purchased loans, including HLC, in federal and state courts in Minnesota and New York. In each case, plaintiff claimed that the defendant is liable for a portion of the global settlement in RFC’s bankruptcy. Plaintiff asserted two claims against HLC: (1) breach of contract based on HLC’s alleged breach of representations and warranties concerning the quality and characteristics of the mortgage loans it sold to RFC; and (2) contractual indemnification for alleged liabilities, losses, and damages incurred by RFC arising out of purported defects in loans that RFC purchased from HLC and sold to third parties. Plaintiff alleged that the “types of defects” contained in the loans it purchased from HLC included “income misrepresentation, employment misrepresentation, appraisal misrepresentations or inaccuracies, undisclosed debt, and missing or inaccurate documents.” Plaintiff sought damages of up to $61.0 million plus attorney's fees and prejudgment interest. HLC denied the material allegations of the complaint and asserted numerous defenses thereto. The matter went to trial in the fourth quarter of 2018 and the jury returned a verdict of $28.7 million in favor of plaintiff. On June 21, 2019, the U.S. District Court in Minnesota entered judgment against HLC for $68.5 million . The judgment is comprised of: (i) $28.7 million in damages awarded by the jury; (ii) $14.1 million in pre-verdict interest; (iii) $23.1 million in attorneys' fees and costs, and (iv) $2.6 million in post-verdict, prejudgment interest. HLC’s filing under the Bankruptcy Code discussed above in Home Loan Center, Inc. Bankruptcy Filing creates an automatic stay of enforcement of the judgment entered against HLC by the U.S. District Court in Minnesota. On August 27, 2019, plaintiff filed a lawsuit captioned ResCap Liquidating Trust v. LendingTree, LCC, et al., Case No. 19-cv-2360 (U.S. Dist. Ct., Minn.) , seeking to hold the Company liable for the judgment against HLC, under assumption of liability, agency and alter ego theories. The Company believes that these claims lack merit and intends to defend this action vigorously. On October 17, 2019, the Company filed a motion to dismiss the liability and agency claims, and oral arguments with respect to such motion were held on January 10, 2020. Lehman Brothers Holdings, Inc. Lehman Brothers Holdings Inc. v. 1st Advantage Mortgage, LLC et al., Case No. 08-13555 (SCC), Adversary Proceeding No. 16-01342 (SCC) (Bankr. S.D.N.Y.). In February 2016, Lehman Brothers Holdings, Inc. (“LBHI”) filed an Adversary Complaint against HLC and approximately 149 other defendants (the "Complaint"). In December 2018, LBHI amended its complaint against HLC. The amended complaint references approximately 370 allegedly defective mortgage loans sold by HLC with purported "Claim Amounts" totaling $40.2 million . LBHI alleges it settled all such claims and is seeking indemnification from HLC for LBHI’s purported losses and liabilities associated with such settlements, plus prejudgment interest, attorneys’ fees, litigation costs and other expenses. The amended complaint does not specify the amount of LBHI’s purported damages. On December 4, 2019, LBHI filed a $44.7 million proof of claim in HLC’s bankruptcy seeking recovery for the claims asserted in the lawsuit. The Company believes that these claims lack merit and understands that HLC intends to defend this action vigorously. HLC’s filing under the Bankruptcy Code discussed above in Home Loan Center, Inc. Bankruptcy Filing creates an automatic stay of this proceeding. Financial Information of Discontinued Operations The components of net loss reported as discontinued operations in the accompanying consolidated statements of operations and comprehensive income are as follows (in thousands) : Year Ended December 31, 2019 2018 2017 Revenue $ — $ — $ (750 ) Gain from removal of HLC's assets and liabilities 4,515 — — Other operating expenses (35,002 ) (16,228 ) (5,159 ) Loss before income taxes (30,487 ) (16,228 ) (5,909 ) Income tax benefit 8,855 3,408 2,069 Net loss $ (21,632 ) $ (12,820 ) $ (3,840 ) Losses from discontinued operations included all activity of HLC prior to bankruptcy, including litigation settlements, contingencies and legal fees associated with legal proceedings, as well as a gain upon deconsolidation due to the accounting effect of HLC’s bankruptcy filing on the consolidated financial statements. The results of discontinued operations also include litigation settlements and contingencies and legal fees associated with ongoing legal proceedings against LendingTree Inc. or LendingTree LLC that arose due to the LendingTree Loans Business or the HLC bankruptcy filing.

Segment Reporting [Abstract]
SEGMENT INFORMATION	SEGMENT INFORMATION The Company manages its business and reports its financial results through the following three operating and reportable segments: Home, Consumer and Insurance. Characteristics which were relied upon in making the determination of the reportable segments include the nature of the products, the organization's internal structure, and the information that is regularly reviewed by the CODM for the purpose of assessing performance and allocating resources. The Company changed its reportable segments in the fourth quarter of 2019 and previously reported segment results have been revised to conform to the Company's reportable segments at December 31, 2019. The Home segment includes the following products: purchase mortgage, refinance mortgage, home equity loans and lines of credit, reverse mortgage loans, and real estate. The Consumer segment includes the following products: credit cards, personal loans, small business loans, student loans, auto loans, deposit accounts, and other credit products such as credit repair and debt settlement. The Insurance segment consists of insurance quote products. Revenue from the resale of online advertising space to third parties and revenue from home improvement referrals, and the related variable marketing and advertising expenses, are included within the Other category. The following tables are a reconciliation of segment profit, which is the Company's primary segment profitability measure, to income before income taxes and discontinued operations. Segment cost of revenue and marketing expense represents the portion of selling and marketing expense attributable to variable costs paid for advertising, direct marketing and related expenses, that are directly attributable to the segments' products. This measure excludes overhead, fixed costs and personnel-related expenses. For the Other category, segment cost of revenue and marketing expense also includes the portion of cost of revenue attributable to costs paid for advertising re-sold to third parties.

SIGNIFICANT ACCOUNTING POLICI_2

SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition The Company derives its revenue primarily from match fees and closing fees. Revenue is recognized when performance obligations under the terms of a contract with a customer are satisfied and promised services have transferred to the customer. In identifying performance obligations, judgment is required around contracts where there was a possibility of bundled services and multiple parties. In applying judgment, the Company considers customer expectations of performance, materiality and the core principles of Accounting Standards Codification ("ASC") Topic 606, Revenue from Contracts with Customers. The Company's services are generally transferred to the customer at a point in time. Variable consideration is included in revenue if it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Revenue from Home products is primarily generated from upfront match fees paid by mortgage Network Partners that receive a loan request, and in some cases upfront fees for clicks or call transfers. Match fees and upfront fees for clicks and call transfers are earned through the delivery of loan requests that originated through the Company's websites or affiliates. The Company recognizes revenue at the time a loan request is delivered to the customer, provided that no significant obligations remain. Revenue recognition on match fees was not impacted by the adoption of ASC Topic 606 in the first quarter of 2018, as the Company's contractual right to the match fee consideration is contemporaneous with the satisfaction of the performance obligation to deliver a loan request to the customer. Revenue from Consumer products is generated by match and other upfront fees for clicks or call transfers, as well as from closing fees, approval fees and upfront service and subscription fees. Closing fees are derived from lenders on certain auto loans, business loans, personal loans and student loans when the lender funds a loan with the consumer. Prior to the adoption of ASC Topic 606, closed loan fees were recognized at the time the lender reported the closed loan to the Company, which could be several months after the original request was transmitted. Approval fees are derived from credit card issuers when the credit card consumer receives card approval from the credit card issuer. Prior to the adoption of ASC Topic 606, approval fees were recognized at the time the credit card issuer reported the card approval for the consumer to the Company, which is generally within two weeks after the consumer's request was transmitted. Upfront service fees and subscription fees are derived from consumers in the Company's credit services product. Upfront fees paid by consumers are recognized as revenue over the estimated time the consumer will remain a customer and receive services. Subscription fees are recognized over the period a consumer is receiving services. Under ASC Topic 606, the timing of recognizing revenue for closing fees and approval fees is accelerated to the point when a loan request or a credit card consumer is delivered to the customer, as opposed to when the consumer loan is closed by the lender or credit card approval is made by the issuer. The Company's contractual right to closing fees and approval fees is not contemporaneous with the satisfaction of the performance obligation to deliver a loan request or a credit card consumer to the customer. As such, the Company records a contract asset at each reporting period-end related to the estimated variable consideration on closing fees and approval fees for which the Company has satisfied the related performance obligation, but are still pending the loan closing or credit card approval before the Company has a contractual right to payment. This estimate is based on the Company's historical closing rates and historical time between when a consumer request for a loan or credit card is delivered to the lender or card issuer and when the loan is closed by the lender or approved by the card issuer. The time between satisfaction of the Company's performance obligation and when the Company's right to consideration becomes unconditional varies across products, but is generally less than 90 days for auto loans, personal loans, student loans and credit card approvals. The time between satisfaction of the Company's performance obligation and when the Company's right to consideration becomes unconditional for small business loans is generally less than 27 months. Revenue from the Company's Insurance products is primarily generated from upfront match fees, and upfront fees for website clicks or fees for calls. Match fees and upfront fees for clicks and call transfers are earned through the delivery of consumer requests that originated through the Company's websites or affiliates. The Company recognizes revenue at the time a consumer request is delivered to the customer, provided that no significant obligations remain. The Company's contractual right to the match fee consideration is contemporaneous with the satisfaction of the performance obligation to deliver a consumer request to the customer. Our payment terms vary by customer and services offered. The term between invoicing and when payment is due is generally 45 days or less. Sales commissions are incremental costs of obtaining contracts with customers. The Company expenses sales commissions when incurred as the duration of contracts with customers is less than one year, based on the right for either party to terminate the contract with less than one year's notice without compensation to either party. These costs are recorded within selling and marketing expense on the consolidated statements of operations and comprehensive income. For additional information on the adoption of ASC Topic 606, see the discussion over ASU 2014-09 in the section titled "Recently Adopted Accounting Pronouncements" within this Note.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash and short-term, highly liquid money market investments with original maturities of three months or less.
Restricted Cash	Restricted Cash Cash escrowed or contractually restricted for a specific purpose is designated as restricted cash.
Accounts Receivable	Accounts Receivable Accounts receivable are stated at amounts due from customers, net of an allowance for doubtful accounts. The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time accounts receivable are past due, previous loss history and the specific customer's current ability to pay its obligation. Accounts receivable are considered past due when they are outstanding longer than the contractual payment terms. Accounts receivable are written off when management deems them uncollectible. A reconciliation of the beginning and ending balances of the allowance for doubtful accounts is as follows (in thousands) : Year Ended December 31, 2019 2018 2017 Balance, beginning of the period $ 1,143 $ 675 $ 1,059 Charges to earnings 1,697 880 195 Write-off of uncollectible accounts receivable (1,374 ) (412 ) (579 ) Balance, end of the period $ 1,466 $ 1,143 $ 675
Segment Reporting	Segment Reporting The Company has three reportable segments: Home, Consumer and Insurance. Characteristics which were relied upon in making the determination of the reportable segments include the nature of the products, the organization's internal structure, and the information that is regularly reviewed by the CODM for the purpose of assessing performance and allocating resources.
Property and Equipment	Property and Equipment Property and equipment, including internally-developed software and significant improvements, are recorded at cost less accumulated depreciation. Due to the rapid advancements in technology and evolution of company products, all internally-developed software is written-off at the end of its useful life. Repairs and maintenance and any gains or losses on dispositions are recognized as incurred in current operations. Depreciation is recorded on a straight-line basis to allocate the cost of depreciable assets to operations over their estimated service lives. The following table presents the estimated useful lives for each asset category: Asset Category Estimated Useful Lives Computer equipment and capitalized software 1 to 5 years Leasehold improvements Lesser of asset life or life of lease Furniture and other equipment 7 years Aircraft and automobile 5 to 10 years
Software Development Costs	Software Development Costs Software development costs primarily include internal and external labor expenses incurred to develop the software that powers the Company's websites. Certain costs incurred during the application development stage are capitalized based on specific activities tracked, while costs incurred during the preliminary project stage and post-implementation/operation stage are expensed as incurred. Capitalized software development costs are amortized over an estimated useful life of one to five years .
Goodwill and Indefinite-Lived Intangible Assets	Goodwill and Indefinite-Lived Intangible Assets Goodwill acquired in business combinations is assigned to the reporting units that are expected to benefit from the combination as of the acquisition date. Goodwill and indefinite-lived intangible assets, consisting of certain trade names and trademarks, are not amortized. Rather, these assets are tested annually for impairment as of October 1, or more frequently upon the occurrence of certain events or substantive changes in circumstances. As part of its annual impairment testing of goodwill and indefinite-lived intangible assets, in each instance, the Company may elect to assess qualitative factors as a basis for determining whether it is necessary to perform the traditional quantitative impairment testing. If the Company’s assessment of these qualitative factors indicates that it is not more likely than not that the fair value of the reporting unit or indefinite-lived intangible asset is less than its carrying value, then no further testing is required. Otherwise, the goodwill reporting unit or long-lived intangible assets, as applicable, must be quantitatively tested for impairment. The quantitative test for goodwill impairment is determined using a two-step process. The first step is to compare the fair value of a reporting unit with its carrying amount, including goodwill. In performing the first step, the Company determines the fair value of its reporting units by using a market approach and a discounted cash flow ("DCF") analysis. Determining fair value using a DCF analysis requires the exercise of significant judgments, including judgments about appropriate discount rates, perpetual growth rates and the amount and timing of expected future cash flows. If the fair value of a reporting unit exceeds its carrying amount, goodwill of the reporting unit is not impaired and the second step of the impairment test is not required. If the carrying amount of a reporting unit exceeds its fair value, the second step of the goodwill impairment test is required to be performed to measure the amount of impairment, if any. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill. The implied fair value of goodwill is determined in the same manner as the amount of goodwill recognized in a business combination. If the carrying amount of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The quantitative impairment test for indefinite-lived intangible assets involves a comparison of the estimated fair value of the intangible asset with its carrying value. If the carrying value of the indefinite-lived intangible asset exceeds its estimated fair value, an impairment loss is recognized in an amount equal to that excess. The estimates of fair value of indefinite-lived intangible assets are determined using a DCF valuation analysis that employs a relief-from-royalty methodology in estimating the fair value of trade names and trademarks. Significant judgments inherent in this analysis include the determination of royalty rates, discount rates, perpetual growth rates and the amount and timing of future revenues. At October 1, 2019, the Company performed the first step of the quantitative goodwill impairment test and found that the fair value of each reporting unit exceeded its carrying amount, indicating no goodwill impairment. The Company changed its operating segments in the fourth quarter of 2019 and accordingly changed its reporting units. At December 31, 2019, the Company performed the first step of the quantitative goodwill impairment test and found that the fair value of each reporting unit exceeded its carrying amount, indicating no goodwill impairment. Results of the October 1, 2019 qualitative annual impairment tests for the indefinite-lived intangible assets indicated that it is not more likely than not that the fair value of the assets were each less than their respective carrying values. Accordingly, no further testing was required. Results of the October 1, 2018 qualitative annual impairment tests indicated that it is not more likely than not that the fair value of the goodwill and the indefinite-lived intangible assets were each less than their respective carrying values. Accordingly, no further testing was required.
Long-Lived Assets and Intangible Assets with Definite Lives	Long-Lived Assets and Intangible Assets with Definite Lives Long-lived assets include property and equipment, definite-lived intangible assets and operating lease right-of-use assets. Amortization of definite-lived intangible assets is recorded on a straight-line basis over their estimated lives. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. The carrying amount 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 amount is deemed to not be recoverable, an impairment loss is recorded as the amount by which the carrying amount of the long-lived asset exceeds its fair value. At December 31, 2019 and 2018, the Company performed its review of impairment triggering events for long-lived assets and determined that a triggering event had not occurred.
Assets and Liabilities Held for Sale	Assets and Liabilities Held for Sale The Company classifies assets or disposal groups to be sold as held for sale in the period in which all of the following criteria are met: • Management, having the authority to approve the action, commits to a plan to sell the asset or disposal group; • The asset or disposal group is available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets or disposal groups; • An active program to locate a buyer and other actions required to complete the plan to sell the asset or disposal group have been initiated; • The sale of the asset or disposal group is probable, and transfer of the asset or disposal group is expected to qualify for recognition as a completed sale within one year, except if events or circumstances beyond the Company's control extend the period of time required to sell the asset or disposal group beyond one year; • The asset or disposal group is being actively marketed for sale at a price that is reasonable in relation to its current fair value; and • Actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. A long-lived asset or disposal group that is classified as held for sale is initially measured at the lower of its carrying value or fair value less any costs to sell. Any loss resulting from this measurement is recognized in the period in which the held for sale criteria are met. Conversely, gains are not recognized on the sale of a long-lived asset or disposal group until the date of sale. The fair value of a long-lived asset or disposal group, less any costs to sell, is assessed each reporting period it remains classified as held for sale and any subsequent changes are reported as an adjustment to the carrying value of the asset or disposal group, as long as the new carrying value does not exceed the carrying value of the asset at the time it was initially classified as held for sale.
Fair Value Measurements	Fair Value Measurements The Company categorizes its assets and liabilities measured at fair value into a fair value hierarchy that prioritizes the assumptions used in pricing the asset or liability into the following three levels: • Level 1 : Observable inputs, such as quoted prices for identical assets and liabilities in active markets obtained from independent sources. • Level 2 : Other inputs that are observable directly or indirectly, such as quoted prices for similar assets or liabilities in active markets, quoted 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. • Level 3 : Unobservable inputs for which there is little or no market data and which require the Company to develop its own assumptions, based on the best information available under the circumstances, about the assumptions market participants would use in pricing the asset or liability. The Company's non-financial assets, such as goodwill, intangible assets and property and equipment are recorded at fair value upon acquisition. These assets are remeasured at fair value when there is an indicator of impairment and recorded at fair value only when an impairment charge is recognized. Such fair value measurements are based predominantly on Level 3 inputs. Contingent consideration payments related to acquisitions are measured at fair value each reporting period using Level 3 unobservable inputs. The Company's estimates of fair value are based upon assumptions believed to be reasonable but which are uncertain and involve significant judgments by management. Any changes in the fair value of these contingent consideration payments are included in operating income in the consolidated statements of operations and comprehensive income.
Cost of Revenue	Cost of Revenue Cost of revenue consists primarily of expenses associated with compensation and other employee-related costs (including stock-based compensation) related to internally-operated customer call centers, third-party customer call center fees, costs for online advertising resold to third parties, credit scoring fees, credit card fees, website network hosting and server fees.
Product Development	Product Development
Advertising	Product development expense consists primarily of compensation and other employee-related costs (including stock-based compensation) and third-party labor costs that are not capitalized, for employees and consultants engaged in the design, development, testing and enhancement of technology. Advertising
Income Taxes	Income Taxes Income taxes are accounted for 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 amounts of existing assets and liabilities and their respective tax bases. In estimating future tax consequences, all expected future events are considered. 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 on deferred tax assets if it is determined that it is more likely than not that the deferred tax asset will not be realized. Interest is recorded on potential tax contingencies as a component of income tax expense and recorded net of any applicable related income tax benefit. For the years ended December 31, 2019 , 2018 and 2017 , the Company followed the incremental or "with" and "without" approach to intraperiod tax allocation for determination of the amount of tax benefit to allocate to continuing operations as prescribed in ASC 740-20-45-7. In accordance with the accounting standard for uncertainty in income taxes, liabilities for uncertain tax positions are recognized based on the two-step process prescribed by the accounting standards. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Effective January 1, 2018, the Company changed the method used to estimate the deduction for prepaid marketing and advertising costs. This change in methodology impacts the timing of the tax deductibility of these related costs. The Company historically estimated these expenses to be deductible if the services were provided within 12 months of payment. Under the proposed method of accounting, the Company will take into account only prepaid marketing and advertising as the Company makes payment for the services to the extent that the payment is due and the services are reasonably expected by the Company to be provided to the applicant within 3 ½-months after the date of payment as authorized by Treas. Reg. §1.461-4(d)(6)(ii). The Company has accounted for this change as a change in accounting method and recorded a cumulative impact of $1.0 million as a deferred tax liability to be recognized over four years. Effective January 1, 2017, the Company changed the method used to estimate the deduction for internally developed software. This change in methodology impacts the timing of the tax deductibility of these related costs. The Company historically capitalized these expenses and amortized them over three years. Under the proposed method of accounting, the Company will treat costs attributable to internally developed software as current expenses and take them into account in full in accordance with Section 5.01(1) of Rev. Proc. 2000-50 and rules similar to those applicable under Section 174(a). The Section 481(a) adjustment is the cumulative difference between the present method and the proposed method of accounting computed as of the first day of the year of change, January 1, 2017 and was reflected in the timely filed income tax return during 2018 related to the period of change. On December 22, 2017, the SEC staff issued Staff Accounting Bulletin No. 118 ("SAB 118"), which provides guidance on accounting for the tax effect of the Tax Cuts and Jobs Act ("TCJA"). SAB 118 provides a measurement period that should not extend beyond one year from the TCJA enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the TCJA for which the accounting under ASC 740 is complete. To the extent that a company's accounting for certain income tax effects of the TCJA is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. In accordance with SAB 118, the Company determined that the $ 9.1 million of the deferred tax expense recorded in connection with the remeasurement of certain deferred tax assets and liabilities was a provisional amount and a reasonable estimate at December 31, 2017. During the fourth quarter of the year ended December 31, 2018, the Company finalized the computations of the income tax effects of the Act. As such, in accordance with SAB 118, the Company's accounting for the effects of the Act is complete. The Company did not significantly adjust provisional amounts recorded in 2017 and the SAB 118 measurement period subsequently ended on December 22, 2018. Although the Company no longer considers these amounts to be provisional, the determination of the Act's income tax effects may change following future legislation or further interpretation of the Act based on future guidance from the Internal Revenue Service and state tax authorities.
Stock-Based Compensation	Stock-Based Compensation The forms of stock-based awards granted to LendingTree employees are principally restricted stock units ("RSUs"), RSUs with performance conditions, stock options and stock options with performance conditions. Further, stock options with market conditions, restricted stock awards ("RSAs") with performance conditions and RSAs with market conditions have been granted to the Company's Chairman and Chief Executive Officer. RSUs are awards in the form of units, denominated in a hypothetical equivalent number of shares of LendingTree common stock and with the value of each award equal to the fair value of LendingTree common stock at the date of grant. RSUs may be settled in cash, stock or both, as determined by the Company's Compensation Committee at the time of grant. The Company does not have a history of settling these awards in cash. Each stock-based award is subject to service-based vesting, where a specific period of continued employment must pass before an award vests. The Compensation Committee can modify the vesting provisions of an award. Certain awards also include performance-based vesting, where certain performance targets set at the time of grant must be achieved before an award vests. LendingTree recognizes as expense non-cash compensation for all stock-based awards for which vesting is considered probable. Forfeitures are recognized when they occur. For service-based awards, non-cash compensation is measured at fair value on the grant date and expensed ratably over the vesting term. The fair value of each stock option award without a market condition is estimated using the Black-Scholes option pricing model, while the fair value of an RSU or restricted stock award is measured as the closing common stock price at the time of grant. For performance-based grants, the fair value is measured on the grant date and recognized as non-cash compensation expense, considering the probability of the targets being achieved. Performance-based grants with a market condition are generally valued using a Monte Carlo simulation model.
Litigation Settlements and Contingencies	Litigation Settlements and Contingencies Litigation settlements and contingencies consists of expenses related to actual or anticipated litigation settlements.
Accounting Estimates	Accounting Estimates Management is required to make certain estimates and assumptions during the preparation of the consolidated financial statements in accordance with GAAP. These estimates and assumptions impact the reported amount of assets and liabilities and disclosures of contingent assets and liabilities as of the date of the consolidated financial statements. They also impact the reported amount of net earnings during any period. Actual results could differ from those estimates.
Certain Risks and Concentrations	Certain Risks and Concentrations LendingTree'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 at December 31, 2019 , consist primarily of cash and cash equivalents and accounts receivable, as disclosed in the consolidated balance sheet. Cash and cash equivalents are in excess of Federal Deposit Insurance Corporation insurance limits, but are maintained with quality financial institutions of high credit. The Company requires certain Network Partners to maintain security deposits with the Company, which in the event of non-payment, would be applied against any accounts receivable outstanding. Due to the nature of the mortgage lending industry, interest rate fluctuations may negatively impact future revenue from the Company's marketplace. For the year ended December 31, 2019 , one network partner accounted for 12% of total consolidated revenue, all of which was recorded within the Insurance segment. No Network Partners accounted for more than 10% of total consolidated revenue for the year ended December 31, 2018 . For the year ended December 31, 2017 , another network partner accounted for 11% of total consolidated revenue, which was recorded within the Home and Consumer segments. Lenders and lead purchasers participating on the Company's marketplace can offer their products directly to consumers through brokers, mass marketing campaigns or through other traditional methods of credit distribution. These lenders and lead purchasers can also offer their products online, either directly to prospective borrowers, through one or more online competitors, or both. If a significant number of potential consumers are able to obtain loans and other products from Network Partners without utilizing the Company's services, the Company's ability to generate revenue may be limited. Because the Company does not have exclusive relationships with the Network Partners whose loans and other financial products are offered on its online marketplace, consumers may obtain offers from these Network Partners without using its service. Other than a support services office in India, the Company's operations are geographically limited to and dependent upon the economic condition of the United States.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2018, the FASB issued ASU 2018-07 which simplifies the accounting for nonemployee share-based payments by expanding the scope of ASC Topic 718, Compensation—Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. Under the new guidance, most of the initial and subsequent measurement for such payments to nonemployees is aligned with the requirements for share-based payments to employees. This ASU is effective for annual and interim reporting periods beginning after December 15, 2018, and early adoption was permitted. Entities must transition to the new guidance through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company early-adopted this ASU during the second quarter of 2018, with no impact to its consolidated financial statements. In May 2017, the FASB issued ASU 2017-09 which clarifies when to account for a change to the terms or conditions of a share-based payment award as a modification. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions or the classification of the award changes as a result of the change in terms or conditions. This ASU is effective prospectively for annual periods beginning on or after December 15, 2017. The Company adopted this ASU during the first quarter of 2018. In November 2016, the FASB issued ASU 2016-18 which is intended to reduce the diversity in the classification and presentation of changes in restricted cash in the statement of cash flows, by requiring entities to combine the changes in cash and cash equivalents and restricted cash in one line. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash in the statement of cash flows. In addition, if more than one line item is recorded on the balance sheet for cash and cash equivalents and restricted cash, a reconciliation between the statement of cash flows and balance sheet is required. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017. The retrospective transition method, requiring adjustment to all comparative periods presented, is required. The Company adopted this ASU during the first quarter of 2018. The adoption resulted in an immaterial reclassification of cash outflows from investing activities to operating activities for 2017. See Note 4 —Cash and Restricted Cash for the reconciliation of cash and cash equivalents and restricted cash reported on the balance sheet to the total of such amounts shown on the statement of cash flows. In August 2016, the FASB issued ASU 2016-15 which addresses eight cash flow classification issues, eliminating the diversity in practice. This ASU is effective for annual and interim reporting periods beginning after December 15, 2017. The retrospective transition method, requiring adjustment to all comparative periods presented, is required unless it is impracticable for some of the amendments, in which case those amendments would be prospectively applied as of the earliest date practicable. The Company adopted this ASU during the first quarter of 2018, and there was no adjustment to prior periods. Pursuant to adoption of this ASU, contingent consideration payments made are classified as cash outflows from financing activities up to the amount of the contingent consideration liability recognized at the acquisition date, and the portion of payments in excess of that initial liability are classified as cash outflows from operating activities. See Note 8 —Business Acquisitions for additional information. In March 2016, the FASB issued ASU 2016-09 which simplifies various aspects related to how share-based payments are accounted for and presented in the financial statements, including the income tax consequences, classification of awards as either equity or liabilities, forfeitures and classification of excess tax benefits on the statement of cash flows. This ASU was effective for annual and interim reporting periods beginning after December 15, 2016. Upon adoption, any adjustments were to be reflected as of the beginning of the fiscal year of adoption. The Company adopted this ASU during the first quarter of 2017. The new standard required excess tax benefits and deficiencies, which arise due to the difference in the measure of stock compensation and the amount deductible for tax purposes, to be recorded in earnings in income tax expense. These excess tax benefits and deficiencies were generally previously recorded in additional paid-in capital and had no impact on net income. The standard required prospective adoption for this portion of the new guidance. Additionally, the new standard required the excess tax benefits and deficiencies to be classified as an operating activity in the accompanying consolidated statements of cash flows. These excess tax benefits and deficiencies were previously recorded as a financing activity in the statement of cash flows. The standard allowed for either prospective or retrospective adoption for the change in presentation in the statement of cash flows. The Company elected to retrospectively adopt the classification change in the statement of cash flows. The standard also allows for an election by the Company to either estimate forfeitures, as required under previous guidance, or recognize forfeitures when they occur. The Company elected to recognize forfeitures of stock awards as they occur, with the modified retrospective transition method required. Accordingly, the Company recognized a $1.4 million cumulative-effect adjustment to retained earnings as of January 1, 2017. In February 2016, the FASB issued ASU 2016-02 related to lease accounting guidance. This ASU introduces ASC Topic 842, Leases, which supersedes ASC Topic 840, Leases. In 2018 and 2019, the FASB issued final amendments clarifying certain narrow aspects of implementing ASU 2016-02, including clarifications related to the rate implicit in the lease, lessee reassessment of lease classification, lessor reassessment of lease term and purchase options, variable payments that depend on an index or rate, transition disclosures and certain other transition matters. The clarification ASUs also provided an optional transition method that allows entities to initially apply the lease accounting transition requirements at the adoption date and recognize a cumulative effect adjustment to the opening balance of retained earnings in the period of adoption without restating comparative prior periods presented. The clarification ASUs must be adopted concurrently with the adoption of ASU 2016-02 (collectively, "ASC Topic 842"). The Company has adopted ASC Topic 842 as of January 1, 2019 using the optional transition method to apply the new requirements at the adoption date without restating comparative prior periods presented. The adoption resulted in the increase in total assets and total liabilities of $8.8 million as of January 1, 2019 related to operating leases greater than one year in duration for which the Company is the lessee, with no cumulative effect adjustment to the opening balance of accumulated deficit. As part of the transition, the Company has elected the package of practical expedients, which allows the Company to not reassess whether expired or existing contracts contain leases, lease classification for expired or existing leases, and initial direct costs for existing leases. Additionally, the Company has elected an accounting policy to not record short-term leases, which are leases with an initial term of twelve months or fewer, on the balance sheet. In May 2014, the FASB issued ASU 2014-09 related to revenue recognition. This guidance introduces ASC Topic 606, Revenue from Contracts with Customers, and supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition. In 2016, the FASB issued final amendments clarifying implementation guidance for principal versus agent considerations, identifying performance obligations, assessing collectability, presenting sales taxes, measuring noncash consideration and certain other transition matters. The clarification ASUs must be adopted concurrently with the adoption of ASU 2014-09 (collectively, "ASC Topic 606"). Under the new ASUs, the timing of recognizing revenue for closing fees and approval fees in the Company's Consumer products has been accelerated to the point when a loan request or a credit card consumer is delivered to the customer as opposed to when the consumer loan is closed by the lender or credit card approval is made by the issuer and communicated to the Company. The Company adopted ASC Topic 606 as of January 1, 2018 using the modified retrospective transition approach. The Company recognized the cumulative effect of initially applying ASC Topic 606 as an adjustment to the opening balance of accumulated deficit. Under this approach, revenue for 2017 is reported in the consolidated statements of operations and comprehensive income on the historical basis, and revenue for 2019 and 2018 is reported in the consolidated statements of operations and comprehensive income under ASC Topic 606. See Note 3 —Revenue for additional information. The cumulative effect of the changes made to the consolidated January 1, 2018 balance sheet for the adoption of ASC Topic 606 were as follows (in thousands) : December 31, Adjustments due to ASC Topic 606 January 1, Assets: Prepaid and other current assets $ 11,881 $ 1,903 $ 13,784 Deferred income tax assets 20,156 (530 ) 19,626 Shareholders' equity: Accumulated deficit $ (708,354 ) $ 1,373 $ (706,981 ) Recently Issued Accounting Pronouncements In December 2019, the Financial Accounting Standards Board ("FASB") issued ASU 2019-12, which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC Topic 740, Income Taxes, and clarifies certain aspects of the current guidance to improve consistency among reporting entities. This ASU is effective for annual and interim reporting periods beginning after December 15, 2020. Early adoption is permitted, including adoption in interim periods. Entities electing early adoption must adopt all amendments in the same period. Most amendments must be applied prospectively while others are to be applied on a retrospective basis for all periods presented or a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The Company is evaluating the impact this ASU will have on its consolidated financial statements and whether to early adopt. In August 2018, the FASB issued ASU 2018-15, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. The amendments should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. The Company does not expect this ASU to have a material impact on its consolidated financial statements and will adopt ASU 2018-15 in the first quarter of 2020 using the prospective approach. In August 2018, the FASB issued ASU 2018-13, which removes, modifies and adds certain disclosure requirements in ASC Topic 820, Fair Value Measurement. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Certain amendments must be applied prospectively while others are to be applied on a retrospective basis to all periods presented. The Company will adopt ASU 2018-13 in the first quarter of 2020. In January 2017, the FASB issued ASU 2017-04, which eliminates the requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge (Step 2 of the goodwill impairment test). Instead, an impairment charge will be based on the excess of the carrying amount over the fair value. This ASU is effective for annual and interim impairment tests performed in periods beginning after December 15, 2019. The Company will adopt ASU 2017-04 in the first quarter of 2020. In June 2016, the FASB issued ASU 2016-13, which requires entities to measure expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This ASU introduces ASC Topic 326, Financial Instruments—Credit Losses, which replaces the existing incurred loss model and is applicable to financial assets measured at amortized cost, including trade receivables and certain other financial assets that have the contractual right to receive cash. ASC Topic 326 is effective for annual and interim reporting periods beginning after December 15, 2019. The guidance must be adopted using a modified retrospective transition. The adoption of ASC Topic 326 is not expected to have a material effect on the Company's consolidated financial statements. The Company will adopt ASC Topic 326 as of January 1, 2020, and does not expect a material cumulative effect adjustment to the opening balance of accumulated deficit in the period of adoption.

Summary of stock option valuation assumptions	For purposes of determining stock-based compensation expense, the weighted average grant date fair value per share of the stock options was estimated using the Black-Scholes option pricing model, which requires the use of various key assumptions. The weighted average assumptions used are as follows: Year Ended December 31, 2019 2018 2017 Expected term (1) 5.00 - 6.25 years 5.00 - 6.71 years 5.00 - 7.00 years Expected dividend (2) — — — Expected volatility (3) 51% - 55% 50% - 53% 51% - 52% Risk-free interest rate (4) 1.46% - 2.55 % 2.33% - 3.06% 1.74% - 2.24% (1) The expected term of stock options granted was calculated using the 'Simplified Method', which utilizes the midpoint between the weighted average time of vesting and the end of the contractual term. This method was utilized for the stock options due to a lack of historical exercise behavior by the Company's employees. (2) For all stock options granted during the years ended December 31, 2019 , 2018 and 2017 , no dividends are expected to be paid over the contractual term of the stock options, resulting in a zero expected dividend rate. (3) The expected volatility rate is based on the historical volatility of the Company's common stock. (4) The risk-free interest rate is specific to the date of grant. The risk-free interest rate is based on U.S. Treasury yields for notes with comparable expected terms as the awards, in effect at the grant date. For purposes of determining stock-based compensation expense, the weighted-average grant date fair value per share of the stock options with a market condition was estimated using the Monte Carlo simulation model, which requires the use of various key assumptions. The weighted-average assumptions used are as follows: Year Ended December 31, 2019 2018 2017 Expected term (1) 7.00 years 7.00 - 7.15 years 7.50 years Expected dividend (2) — — — Expected volatility (3) 51% 50% 50% Risk-free interest rate (4) 2.54% 2.38% - 2.81% 2.12% (1) The expected term of stock options with a market condition granted was calculated using the midpoint between the weighted average time of vesting and the end of the contractual term. (2) For all stock options with a market condition granted during the years ended December 31, 2019 , 2018 and 2017 , no dividends are expected to be paid over the contractual term of the stock options, resulting in a zero expected dividend rate. (3) The expected volatility rate is based on the historical volatility of the Company's common stock. (4) The risk-free interest rate is specific to the date of grant. The risk-free interest rate is based on U.S. Treasury yields for notes with comparable expected terms as the awards, in effect at the grant date. For purposes of determining stock-based compensation expense, the weighted average grant date fair value per share of the stock options was estimated using the Black-Scholes option pricing model, which requires the use of various key assumptions. The weighted average assumptions used are as follows: Year ended December 31, 2017 Expected term (1) 5.50 - 6.00 years Expected dividend (2) — Expected volatility (3) 51% Risk-free interest rate (4) 2.16% - 2.23% (1) The expected term of stock options granted was calculated using the 'Simplified Method', which utilizes the midpoint between the weighted average time of vesting and the end of the contractual term. This method was utilized for the stock options due to a lack of historical exercise behavior by the Company's employees. (2) For all stock options granted during the year ended December 31, 2017, no dividends are expected to be paid over the contractual term of the stock options, resulting in a zero expected dividend rate. (3) The expected volatility rate is based on the historical volatility of the Company's common stock. (4) The risk-free interest rate is specific to the date of grant. The risk-free interest rate is based on U.S. Treasury yields for notes with comparable expected terms as the awards, in effect at the grant date.
