Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Company Overview LendingTree, Inc. ("LendingTree" or the "Company"), is the parent of LendingTree, LLC and several companies owned by LendingTree, LLC. 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. Intercompany transactions and accounts have been eliminated. Discontinued Operations 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 17 — Discontinued Operations and Note 18 — Subsequent Event for additional information. Basis of Presentation The accompanying unaudited interim consolidated financial statements as of June 30, 2019 and for the three and six months ended June 30, 2019 and 2018 , respectively, have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission ("SEC"). In the opinion of management, the unaudited interim consolidated financial statements have been prepared on the same basis as the audited financial statements, and include all adjustments, consisting only of normal recurring adjustments, necessary for the fair statement of the Company's financial position for the periods presented. The results for the three and six months ended June 30, 2019 are not necessarily indicative of the results to be expected for the year ending December 31, 2019 , or any other period. The accompanying consolidated balance sheet as of December 31, 2018 was derived from audited financial statements included in the Company's annual report on Form 10-K for the year ended December 31, 2018 (the " 2018 Annual Report"). The accompanying consolidated financial statements do not include all of the information and footnotes required by GAAP for annual financial statements. Accordingly, they should be read in conjunction with the audited financial statements and notes thereto included in the 2018

SIGNIFICANT ACCOUNTING POLICIES

Accounting Policies [Abstract]
SIGNIFICANT ACCOUNTING POLICIES	SIGNIFICANT ACCOUNTING POLICIES 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; 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 June 30, 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 generally 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. 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 services. 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. Litigation Settlements and Contingencies Litigation settlements and contingencies consists of expenses related to actual or anticipated litigation settlements. Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. Early adoption is permitted, including adoption in any interim period. The amendments should be applied either retrospectively or prospectively to all implementation costs incurred after the date 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 2018-13 which removes, modifies and adds certain disclosure requirements in Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurement. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019, with early adoption permitted. Entities are permitted to adopt any removed or modified disclosures and delay adoption of the additional disclosures until the effective date of the ASU. Certain amendments must be applied prospectively while others are to be applied on a retrospective basis to all periods presented. The Company is evaluating the impact this ASU will have on its consolidated financial statements and whether to early adopt. 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. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is evaluating the impact this ASU will have on its consolidated financial statements and whether to early adopt. 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. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted beginning after December 15, 2018, including adoption in interim periods. The guidance must be adopted using a modified retrospective transition. The Company is evaluating the impact this ASU will have on its consolidated financial statements and whether to early adopt. 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.

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Revenue is as follows (in thousands) : Three Months Ended Six Months Ended 2019 2018 2019 2018 Revenue: Mortgage products $ 54,618 $ 66,948 $ 100,602 $ 140,410 Non-mortgage products Credit cards 56,045 38,747 110,551 84,879 Personal loans 41,109 36,210 73,640 62,175 Insurance 71,941 13 139,033 26 Other 54,708 42,183 116,985 77,646 Total non-mortgage products 223,803 117,153 440,209 224,726 Total revenue $ 278,421 $ 184,101 $ 540,811 $ 365,136 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. The Company's services are generally transferred to the customer at a point in time. Revenue within the mortgage product category 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. 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. In addition to match and other upfront fees, revenue within the non-mortgage product category is also generated from closing fees and approval 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. Approval fees are derived from credit card issuers when the credit card consumer receives card approval from the credit card issuer. The Company recognizes revenue on closing fees and approval fees at the point when a loan request or a credit card consumer is delivered to the customer. 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. Revenue from the Company's insurance business is primarily generated from match fees, 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. Upfront fees and subscription fees are derived from consumers in the Company's credit services business. 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. The contract asset recorded within prepaid and other current assets on the consolidated balance sheets related to estimated variable consideration was $5.3 million and $4.8 million on June 30, 2019 and December 31, 2018 , respectively. The contract liability recorded within accrued expenses and other current liabilities on the consolidated balance sheets related to upfront fees paid by consumers in the Company's credit services business was $0.8 million and $0.4 million at June 30, 2019 and December 31, 2018 , respectively. During the second quarter and first six months of 2019 , the Company recognized revenue of $0.1 million and $0.4 million , respectively, that was included in the contract liability balance at December 31, 2018. Revenue recognized in any reporting period includes estimated variable consideration for which the Company has satisfied the related performance obligations, but are still pending the occurrence or non-occurrence of a future event outside the Company's control (such as lenders providing loans to consumers or credit card approvals of consumers) before the Company has a contractual right to payment. The Company recognized an increase to such revenue from prior periods of $0.5 million and $0.2 million in the second quarters of 2019 and 2018, respectively.

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. In February 2019, the Company agreed to sell these buildings to an unrelated third party, which agreement was amended in March 2019. The sale was finalized 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. The properties were associated with the Company's one reportable segment.

LendingTree Loans On June 6, 2012, the Company sold substantially all of the operating assets of its 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 the LendingTree Loans business 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 agreement with Discover for certain loan loss obligations that remain with the Company following the sale. During the second quarter of 2018, the remaining funds in escrow were released to the Company in accordance with the terms of the agreement with Discover. Significant Assets and Liabilities of LendingTree Loans Upon closing of the sale of substantially all of the operating assets of the LendingTree Loans business on June 6, 2012, LendingTree Loans ceased to originate consumer loans. Liability for losses on previously sold loans will remain with LendingTree Loans and are discussed below. Loan Loss Obligations LendingTree Loans sold loans it originated to investors on a servicing-released basis, so the risk of loss or default by the borrower was generally transferred to the investor. However, LendingTree Loans 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. Subsequent to the loan sale, if underwriting deficiencies, borrower fraud or documentation defects are discovered in individual loans, LendingTree Loans may be obligated to repurchase the respective loan or indemnify the investors for any losses from borrower defaults if such deficiency or defect cannot be cured within the specified period following discovery. HLC, a subsidiary of the Company, continues to be liable for these indemnification obligations, repurchase obligations and premium repayment obligations following the sale of substantially all of the operating assets of its LendingTree Loans business in the second quarter of 2012. The following table represents the aggregate loans sold, subsequent settlements and remaining unsettled loans. Number of Loans Original Issue Balance (in thousands) (in billions) Loans sold by HLC 234 $ 38.9 Subsequent settlements (172 ) (28.8 ) Remaining unsettled balance as of June 30, 2019 62 $ 10.1 During the fourth quarter of 2015, LendingTree Loans completed a settlement agreement for $0.6 million with one of the investors to which it had sold loans. This investor accounted for approximately 10% of the total number of loans sold and 12% of the original issue balance. This settlement related to all existing and future losses on loans sold to this investor. During the fourth quarter of 2014, LendingTree Loans completed a settlement agreement for $5.4 million with the largest investor to which it had sold loans. This investor accounted for approximately 40% of both the total number of loans sold and the original issue balance. This settlement related to all existing and future losses on loans sold to this investor. In the second quarter of 2014, LendingTree Loans completed settlements with two buyers of previously purchased loans. The Company has been negotiating with certain of the remaining secondary market purchasers to settle any existing and future contingent liabilities, but it may not be able to complete such negotiations on acceptable terms, or at all. Because LendingTree Loans does not service the loans it sold, it does not maintain nor generally have access to the current balances and loan performance data with respect to the individual loans previously sold to investors. Accordingly, LendingTree Loans is unable to determine, with precision, its maximum exposure for breaches of the representations and warranties it made to the investors that purchased such loans. The Company uses a settlement discount framework for evaluating the adequacy of the reserve for loan losses. This model estimates lifetime losses on the population of remaining loans originated and sold by LendingTree Loans using actual defaults for loans with similar characteristics and projected future defaults. It also considers the likelihood of claims expected due to alleged breaches of representations and warranties made by LendingTree Loans and the percentage of those claims investors estimate LendingTree Loans may agree to repurchase. A settlement discount factor is then applied to the result of the foregoing to reflect publicly-announced bulk settlements for similar loan types and vintages, the Company's own settlement experience, as well as LendingTree Loans' non-operating status, in order to estimate a range of potential obligation. The estimated range of remaining loan losses using this settlement discount framework was determined to be $4.3 million to $7.9 million at June 30, 2019 . The reserve balance recorded as of June 30, 2019 was $7.6 million . Management has considered both objective and subjective factors in the estimation process, but given current general industry trends in mortgage loans as well as housing prices and market expectations, actual losses related to LendingTree Loans' obligations could vary significantly from the obligation recorded as of the balance sheet date or the range estimated above. Additionally, LendingTree has guaranteed certain loans sold to two investors in the event that LendingTree Loans is unable to satisfy its repurchase and warranty obligations related to such loans. Based on historical experience, it is anticipated that LendingTree Loans will continue to receive repurchase requests and incur losses on loans sold in prior years. The activity related to loss reserves on previously sold loans is as follows (in thousands) : Three Months Ended Six Months Ended 2019 2018 2019 2018 Loan loss reserve, beginning of period $ 7,554 $ 7,554 $ 7,554 $ 7,554 Provisions — — — — Charge-offs to reserves — — — — Loan loss reserve, end of period $ 7,554 $ 7,554 $ 7,554 $ 7,554 The liability for losses on previously sold loans is presented as current liabilities of discontinued operations in the accompanying consolidated balance sheets as of June 30, 2019 and December 31, 2018 .

BUSINESS ACQUISITION	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. The preliminary allocation of purchase price to the assets acquired and liabilities assumed is as follows (in thousands): Preliminary Fair Value Net working capital $ 2,796 Fixed assets 68 Intangible assets 31,600 Goodwill 71,444 Net noncurrent assets 324 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 cost replacement analysis, the content was determined using excess earnings analysis, and the trademarks and tradenames were determined using relief from royalty analysis. The fair value of the intangible assets with definite lives are as follows (dollars in thousands) : Preliminary 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 As of June 30, 2019 , the Company has not completed its determination of the final allocation of the purchase price to the assets and liabilities of the acquisition. The final allocation of purchase price is expected to be finalized in 2019. Any adjustment to the assets and liabilities assumed with the acquisition will adjust goodwill. The Company recorded preliminary goodwill of $71.4 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 is recorded in the Company’s one reportable segment. For income tax purposes, the Company preliminarily accounted for the acquisition as an asset purchase which would indicate the goodwill will be tax deductible. As of June 30, 2019, the Company has completed the assessment of this election to treat the acquisition as an asset purchase and the election will be timely filed. Subsequent to the acquisition date, the Company’s consolidated results of operations include the results of the acquired ValuePenguin business. In the second quarter and first six months of 2019, the Company’s consolidated results of operations include revenue of $5.5 million and $10.9 million , respectively, and net income from continuing operations of $1.2 million and $3.1 million , respectively. Acquisition-related costs were $0.1 million in the first six months of 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 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. As of June 30, 2019 , the estimated fair value of the contingent consideration totaled $37.6 million , of which $22.4 million is included in current contingent consideration and $15.2 million 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 the second quarter and first six months of 2019, the Company recorded $2.5 million and $16.9 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.

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 excess earnings analysis, the customer relationships were determined using the distributor method, the content was determined using cost replacement analysis, and the trademarks and tradenames were determined using relief from royalty analysis.

The final allocation of purchase price is expected to be finalized in the third quarter of 2019. Any adjustment to the assets and liabilities assumed with the acquisition will adjust goodwill. The Company recorded preliminary goodwill of $183.0 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 is recorded in the Company’s one reportable segment. For income tax purposes, the acquisition was an asset purchase and the goodwill will be tax deductible. The unaudited pro forma financial results for the second quarter and first six months of 2018 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.

Ovation On June 11, 2018, the Company acquired Ovation Credit Services, Inc., a leading provider of credit services with a strong customer service reputation. Ovation utilizes a proprietary software application that facilitates the credit repair process and is integrated directly with certain credit bureaus while educating consumers on credit improvement via ongoing outreach with Ovation case advisors. The proprietary software application offers consumers a simple, streamlined process to identify, dispute, and correct inaccuracies within their credit reports. The Company paid $12.2 million in initial cash consideration and could make up to two additional earnout payments, each ranging from zero to $4.375 million , based on certain defined operating metrics during the earnout periods July 1, 2018 through June 30, 2019 and July 1, 2019 through June 30, 2020. These additional payments, to the extent earned, will be payable in cash. The purchase price of $17.9 million is comprised of the upfront cash payment of $12.2 million , $5.8 million for the estimated fair value of the earnout payments, and a $0.1 million post-closing receipt for working capital settlement. As of June 30, 2019 , the estimated fair value of the contingent consideration totaled $7.4 million , of which $4.3 million is included in current contingent consideration and $3.1 million 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 the second quarter of 2019, the Company recorded contingent consideration expense of $0.6 million in the consolidated statement of operations and comprehensive income due to the change in estimated fair value of the contingent consideration.

The goodwill is primarily attributable to Ovation as a going concern, which represents the ability of the Company to earn a higher return on the collection of assets and business of Ovation 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 is recorded in the Company’s one reportable segment. For income tax purposes, the acquisition was an equity purchase and the goodwill will not be tax deductible. Changes in Contingent Consideration SnapCap On September 19, 2017, the Company acquired certain assets of Snap Capital LLC, which does business under the name SnapCap (“SnapCap”). SnapCap, a tech-enabled online platform, connects business owners with lenders offering small business loans, lines of credit and merchant cash advance products through a concierge-based sales approach. The Company paid $11.9 million of initial cash consideration and could make up to three additional contingent consideration payments, each ranging from zero to $3.0 million , based on certain defined operating results during the periods of October 1, 2017 through September 30, 2018, October 1, 2018 through September 30, 2019 and October 1, 2019 through March 31, 2020. These additional payments, to the extent earned, will be payable in cash. In the first quarter of 2019, the Company paid $3.0 million related to the earnout payment for the period of October 1, 2017 through September 30, 2018, which is included within cash flows from financing activities on the consolidated statement of cash flows. As of June 30, 2019 , the estimated fair value of the contingent consideration totaled $5.2 million , of which $2.9 million is included in current contingent consideration and $2.3 million 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 the second quarter and first six months of 2019, the Company recorded a gain of $0.1 million and contingent consideration expense of $1.5 million , respectively, in the consolidated statements of operations and comprehensive income due to the change in estimated fair value of the contingent consideration. 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. 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. 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 the first six months of 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 June 30, 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 the second quarter and first six months of 2019, the Company recorded gains of $0.2 million and $1.0 million , respectively, in the consolidated statements of operations and comprehensive income due to the change in estimated fair value of the contingent consideration. Pro forma Financial Results The unaudited pro forma financial results for the first six months of 2019 and the second quarter and first six months of 2018 combine the consolidated results of the Company and Ovation, Student Loan Hero, Inc. (“Student Loan Hero”), QuoteWizard and ValuePenguin, giving effect to the acquisitions as if the Ovation, Student Loan Hero and QuoteWizard acquisitions had been completed on January 1, 2017, and as if the ValuePenguin acquisition had been completed on January 1, 2018. This unaudited pro forma financial information is presented for informational purposes only and is not indicative of future operations or results had the acquisitions been completed as of January 1, 2017 or 2018, 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. Depreciation expense and interest expense was adjusted for the impact of the QuoteWizard acquisition, as described above. Interest expense was also adjusted to reflect incremental interest associated with debt issued to finance the ValuePenguin acquisition. The provision for income taxes from continuing operations has 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. Three Months Ended June 30, Six Months Ended June 30, 2018 2019 2018 (in thousands) Pro forma revenue $ 234,264 $ 541,326 $ 464,148 Pro forma net income from continuing operations $ 44,314 $ 13,250 $ 79,902 The unaudited pro forma net income from continuing operations in the first six months of 2019 includes the aggregate after tax contingent consideration expense associated with the DepositAccounts, SnapCap, Ovation and QuoteWizard earnouts of $12.6 million . The unaudited pro forma net income from continuing operations in the second quarter and first six months of 2018 includes the aggregate after tax contingent consideration gain associated with the DepositAccounts and SnapCap earnouts of $0.3 million and $1.1 million , respectively. The unaudited pro forma net income from continuing operations for the first six months of 2018 has been adjusted to include acquisition-related costs of $0.6 million incurred by the Company that are directly attributable to the ValuePenguin acquisition, and which will not have an ongoing impact. Accordingly, such acquisition-related costs have been eliminated from the unaudited pro forma net income from continuing operations for the first six months of 2019. Acquisition-related costs incurred by the Company, Student Loan Hero and QuoteWizard that are directly attributable to the Ovation, Student Loan Hero and QuoteWizard acquisitions, and which will not have an ongoing impact, have been eliminated from the unaudited pro forma net income from continuing operations for the second quarter and first six months of 2018.

The intrinsic value changes based on the market value of the Company's common stock. (b) During the six months ended June 30, 2019 , the Company granted stock options to certain employees and members of the board of directors with a weighted average grant date fair value per share of $166.39 , calculated using the Black-Scholes option pricing model, which vesting periods include (a) immediate vesting on grant date (b) 1 year from grant date (c) three years from grant date and (d) four years from 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: Expected term (1) 5.00 - 6.25 years Expected dividend (2) — Expected volatility (3) 51 - 55% Risk-free interest rate (4) 1.88% - 2.55% (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 in 2019 , 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 intrinsic value changes based on the market value of the Company's common stock. (b) During the six months ended June 30, 2019 , the Company granted stock options with a grant date fair value per share of $230.81 , calculated using the Monte Carlo simulation model, which has a vesting date of March 31, 2023. For purposes of determining stock-based compensation expense, the grant date fair value per share of the stock options was estimated using the Monte Carlo simulation model, which requires the use of various key assumptions. The assumptions used are as follows: Expected term (1) 7.00 years Expected dividend (2) — Expected volatility (3) 51% Risk-free interest rate (4) 2.54% (1) The expected term of stock options with a market condition granted was calculated using the midpoint between the time of vesting and the end of the contractual term. (2) For all stock options with a market condition granted in 2019, 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 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 September 30, 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 June 30, 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 are separated into a debt and 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. In the first six months of 2019, the Company recorded interest expense on the Notes of $7.5 million which consisted of $0.9 million associated with the 0.625% coupon rate, $5.9 million associated with the accretion of the debt discount, and $0.7 million associated with the amortization of the debt issuance costs. In the first six months of 2018, the Company recorded interest expense on the Notes of $7.2 million which consisted of $0.9 million associated with the 0.625% coupon rate, $5.6 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 June 30, 2019, the fair value of the Notes is estimated to be approximately $628.3 million using the Level 1 observable input of the last quoted market price on June 28, 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) : June 30, December 31, Gross carrying amount $ 300,000 $ 300,000 Unamortized debt discount 37,877 43,805 Debt issuance costs 4,541 5,252 Net carrying amount $ 257,582 $ 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 November 21, 2017, the Company's wholly-owned subsidiary, LendingTree, LLC, entered into an amended and restated $250.0 million five -year senior secured revolving credit facility which matures on November 21, 2022 (the “Revolving Credit Facility”). Under certain conditions, the Company will be permitted to add one or more term loans and/or increase revolving commitments under the Revolving Credit Facility by an additional $100.0 million or a greater amount provided that a total consolidated senior secured debt to EBITDA ratio does not exceed 2.50 to 1.00. On October 26, 2018, the Company amended the Revolving Credit Facility to increase the borrowing capacity by $100.0 million to $350.0 million . Pricing and other terms and conditions of the Revolving Credit Facility remain unchanged. Borrowings under the Revolving Credit Facility can be used to finance working capital needs, capital expenditures and general corporate purposes, including to finance permitted acquisitions. As of June 30, 2019 , the Company had $115.0 million in borrowings outstanding under the Revolving Credit Facility at the LIBO rate option with a weighted average interest rate of 3.91% , consisting of a $65.0 million 31-day borrowing and a $50.0 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 Revolving Credit Facility will be available for short-term loans, referred to as swingline loans. Additionally, up to $10.0 million of the Revolving Credit Facility will be available for the issuance of letters of credit. The Company’s borrowings under the 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 SunTrust 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 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 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 June 30, 2019 . The 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 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. In addition to the remaining unamortized debt issuance costs associated with the original revolving credit facility entered into on October 22, 2015 and the Revolving Credit Facility, debt issuance costs of $0.5 million related to the October 2018 amendment are being amortized to interest expense over the life of the Revolving Credit Facility, and are included in prepaid and other current assets and other non-current assets in the Company's consolidated balance sheet. In the first six months of 2019, the Company recorded interest expense related to the Revolving Credit Facility of $3.8 million , which consisted of $3.2 million associated with borrowings bearing interest at the LIBO rate, $0.3 million in unused commitment fees, and $0.3 million associated with the amortization of the debt issuance costs. In the first six months of 2018, the Company recorded interest expense related to the Revolving Credit Facility of $0.4 million in unused commitment fees and $0.2 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 business. With respect to the matters disclosed in this Note 14 , 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 June 30, 2019 , the Company had litigation settlement accruals of $0.1 million and $8.0 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. Specific Matters 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 asserts 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 alleges 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 claims 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. On July 21, 2019, at the direction of HLC’s sole independent director, 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, in order to preserve assets for the benefit of all creditors of HLC. The filing does not include as debtors LendingTree, Inc., LendingTree, LLC or any of their respective subsidiaries engaged in continuing operations. HLC’s filing under the Bankruptcy Code creates an automatic stay of enforcement of the judgment entered against HLC by the U.S. District Court in Minnesota. HLC has filed a motion for relief from stay to appeal that judgement and has asserted that it has strong grounds for such appeal. See Note 18 —Subsequent Event to the consolidated financial statements included elsewhere in this report for further information on the bankruptcy filing by HLC. The Company estimates the range of HLC’s potential losses in the RFC matter to be $0.0 million to $68.5 million . An estimated liability of $7.0 million for this matter is included in the accompanying consolidated balance sheet as of June 30, 2019 . 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. HLC believes that these claims lack merit and intends to defend this action vigorously. An estimated liability of $1.0 million for this matter is included in the accompanying consolidated balance sheet as of June 30, 2019 .

See Note 13 —Debt for additional information on the 0.625% Convertible Senior 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 second quarters and first six months of 2019 and 2018 are as follows (in thousands) : Three Months Ended Six Months Ended 2019 2018 2019 2018 Contingent consideration, beginning of period $ 49,429 $ 33,108 $ 38,837 $ 57,349 Transfers into Level 3 — — — — Transfers out of Level 3 — — — — Total net losses (gains) included in earnings (realized and unrealized) 2,790 (167 ) 17,382 (908 ) Purchases, sales and settlements: Additions — 5,800 — 5,800 Payments (2,000 ) (23,500 ) (6,000 ) (47,000 ) Contingent consideration, end of period $ 50,219 $ 15,241 $ 50,219 $ 15,241 The contingent consideration liability at June 30, 2019 is the estimated fair value of the earnout payments of the DepositAccounts, SnapCap, Ovation and QuoteWizard acquisitions. The Company will make payments ranging from zero to $1.0 million based on the achievement of defined milestone targets for DepositAccounts, payments ranging from zero to $6.0 million based on the achievement of certain defined earnings targets for SnapCap, payments ranging from $4.4 million to $8.8 million based on the achievement of certain defined operating metrics for Ovation, and payments ranging from zero to $70.2 million based on the achievement of certain defined performance targets for QuoteWizard. See Note 7 —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. In February 2019, the Company agreed to sell these buildings to an unrelated third party, which agreement was amended in March 2019. The sale was finalized 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. The properties were associated with the Company's 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 revenue and net loss reported as discontinued operations in the accompanying consolidated statements of operations and comprehensive income are as follows (in thousands) : Three Months Ended Six Months Ended 2019 2018 2019 2018 Revenue $ — $ — $ — $ — Loss before income taxes $ (966 ) $ (2,914 ) $ (2,310 ) $ (8,399 ) Income tax benefit 203 612 485 1,764 Net loss $ (763 ) $ (2,302 ) $ (1,825 ) $ (6,635 ) During the second quarters and first six months of 2019 and 2018, loss from discontinued operations was primarily due to litigation settlements and contingencies and legal fees associated with ongoing legal proceedings. LendingTree Loans On June 6, 2012, the Company sold substantially all of the operating assets of its 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 the LendingTree Loans business 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 agreement with Discover for certain loan loss obligations that remain with the Company following the sale. During the second quarter of 2018, the remaining funds in escrow were released to the Company in accordance with the terms of the agreement with Discover. Significant Assets and Liabilities of LendingTree Loans Upon closing of the sale of substantially all of the operating assets of the LendingTree Loans business on June 6, 2012, LendingTree Loans ceased to originate consumer loans. Liability for losses on previously sold loans will remain with LendingTree Loans and are discussed below. Loan Loss Obligations LendingTree Loans sold loans it originated to investors on a servicing-released basis, so the risk of loss or default by the borrower was generally transferred to the investor. However, LendingTree Loans 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. Subsequent to the loan sale, if underwriting deficiencies, borrower fraud or documentation defects are discovered in individual loans, LendingTree Loans may be obligated to repurchase the respective loan or indemnify the investors for any losses from borrower defaults if such deficiency or defect cannot be cured within the specified period following discovery. HLC, a subsidiary of the Company, continues to be liable for these indemnification obligations, repurchase obligations and premium repayment obligations following the sale of substantially all of the operating assets of its LendingTree Loans business in the second quarter of 2012. The following table represents the aggregate loans sold, subsequent settlements and remaining unsettled loans. Number of Loans Original Issue Balance (in thousands) (in billions) Loans sold by HLC 234 $ 38.9 Subsequent settlements (172 ) (28.8 ) Remaining unsettled balance as of June 30, 2019 62 $ 10.1 During the fourth quarter of 2015, LendingTree Loans completed a settlement agreement for $0.6 million with one of the investors to which it had sold loans. This investor accounted for approximately 10% of the total number of loans sold and 12% of the original issue balance. This settlement related to all existing and future losses on loans sold to this investor. During the fourth quarter of 2014, LendingTree Loans completed a settlement agreement for $5.4 million with the largest investor to which it had sold loans. This investor accounted for approximately 40% of both the total number of loans sold and the original issue balance. This settlement related to all existing and future losses on loans sold to this investor. In the second quarter of 2014, LendingTree Loans completed settlements with two buyers of previously purchased loans. The Company has been negotiating with certain of the remaining secondary market purchasers to settle any existing and future contingent liabilities, but it may not be able to complete such negotiations on acceptable terms, or at all. Because LendingTree Loans does not service the loans it sold, it does not maintain nor generally have access to the current balances and loan performance data with respect to the individual loans previously sold to investors. Accordingly, LendingTree Loans is unable to determine, with precision, its maximum exposure for breaches of the representations and warranties it made to the investors that purchased such loans. The Company uses a settlement discount framework for evaluating the adequacy of the reserve for loan losses. This model estimates lifetime losses on the population of remaining loans originated and sold by LendingTree Loans using actual defaults for loans with similar characteristics and projected future defaults. It also considers the likelihood of claims expected due to alleged breaches of representations and warranties made by LendingTree Loans and the percentage of those claims investors estimate LendingTree Loans may agree to repurchase. A settlement discount factor is then applied to the result of the foregoing to reflect publicly-announced bulk settlements for similar loan types and vintages, the Company's own settlement experience, as well as LendingTree Loans' non-operating status, in order to estimate a range of potential obligation. The estimated range of remaining loan losses using this settlement discount framework was determined to be $4.3 million to $7.9 million at June 30, 2019 . The reserve balance recorded as of June 30, 2019 was $7.6 million . Management has considered both objective and subjective factors in the estimation process, but given current general industry trends in mortgage loans as well as housing prices and market expectations, actual losses related to LendingTree Loans' obligations could vary significantly from the obligation recorded as of the balance sheet date or the range estimated above.

Subsequent Events [Abstract]
SUBSEQUENT EVENT	SUBSEQUENT EVENT On July 21, 2019, at the direction of the sole independent director of the Company’s Home Loan Center, Inc. (“HLC”) subsidiary, 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 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 Note 14 —Contingencies. The judgment against HLC exceeded the assets of HLC, which were approximately $11.4 million at July 21, 2019, including cash of approximately $5.9 million , which approximate the assets of HLC as of June 30, 2019. The bankruptcy filing does not include as debtors LendingTree, Inc., LendingTree, LLC or any of their respective subsidiaries engaged in continuing operations. 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 in Note 14 —Contingencies. HLC’s independent director has advised the Company that HLC, as debtor-in-possession in bankruptcy, intends to pursue an appeal of the judgment entered in ResCap Liquidating Trust v. Home Loan Center, Inc . As a result of the voluntary petition, the Company was, as of the 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 will be deconsolidated from the Company’s consolidated financial statements beginning with the consolidated financial statements for the third quarter of 2019. The effect of such deconsolidation will be elimination of the consolidated assets and liabilities of HLC (and its consolidated subsidiary) from the Company’s consolidated balance sheets and could result in a gain or loss in the third quarter of 2019. Additionally, any successful claims asserted against LendingTree Inc. or LendingTree LLC, such as the claim described below, could also affect any resulting gain or loss upon deconsolidation. In its filings with the Bankruptcy Court, HLC has indicated that it believes that it has claims against HLC’s sole shareholder, the Company’s operating subsidiary LendingTree, LLC, and its former sole director (the Company’s Chairman and Chief Executive Officer), 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 HLC’s former sole director related to these claims and to indemnify such former sole director to the maximum extent permitted by law. The Company 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. The Company has commenced settlement talks with HLC, and if the Company is not able to settle HLC’s claims relating to such dividend declaration on terms the Company deems acceptable, the Company intends to vigorously contest such claims. Any settlement agreement with HLC that the Company might enter into would be subject to approval by the Bankruptcy Court. HLC’s voluntary petition under the Bankruptcy Code does not represent an event of default under LendingTree, LLC’s Amended and Restated Credit Agreement dated as of November 21, 2017 or the Company’s indenture dated May 31, 2017 with respect to the Company’s 0.625% Convertible Senior Notes due 2022.

SIGNIFICANT ACCOUNTING POLICI_2

SIGNIFICANT ACCOUNTING POLICIES (Policies)	6 Months Ended
	Jun. 30, 2019
Accounting Policies [Abstract]
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 June 30, 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 generally 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. 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 services. 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.
Litigation Settlements and Contingencies	Litigation Settlements and Contingencies Litigation settlements and contingencies consists of expenses related to actual or anticipated litigation settlements.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("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. Early adoption is permitted, including adoption in any interim period. The amendments should be applied either retrospectively or prospectively to all implementation costs incurred after the date 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 2018-13 which removes, modifies and adds certain disclosure requirements in Accounting Standards Codification ("ASC") Topic 820, Fair Value Measurement. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019, with early adoption permitted. Entities are permitted to adopt any removed or modified disclosures and delay adoption of the additional disclosures until the effective date of the ASU. Certain amendments must be applied prospectively while others are to be applied on a retrospective basis to all periods presented. The Company is evaluating the impact this ASU will have on its consolidated financial statements and whether to early adopt. 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. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The Company is evaluating the impact this ASU will have on its consolidated financial statements and whether to early adopt. 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. This ASU is effective for annual and interim reporting periods beginning after December 15, 2019. Early adoption is permitted beginning after December 15, 2018, including adoption in interim periods. The guidance must be adopted using a modified retrospective transition. The Company is evaluating the impact this ASU will have on its consolidated financial statements and whether to early adopt. 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.

The intrinsic value changes based on the market value of the Company's common stock.
Schedule 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: Expected term (1) 5.00 - 6.25 years Expected dividend (2) — Expected volatility (3) 51 - 55% Risk-free interest rate (4) 1.88% - 2.55% (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 in 2019 , 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 grant date fair value per share of the stock options was estimated using the Monte Carlo simulation model, which requires the use of various key assumptions. The assumptions used are as follows: Expected term (1) 7.00 years Expected dividend (2) — Expected volatility (3) 51% Risk-free interest rate (4) 2.54% (1) The expected term of stock options with a market condition granted was calculated using the midpoint between the time of vesting and the end of the contractual term. (2) For all stock options with a market condition granted in 2019, 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.
