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 include: 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; litigation accruals; contract assets; various other allowances, reserves and accruals; assumptions related to the determination of stock-based compensation; and the determination of right-of-use assets and lease liabilities. The Company considered the impact of the current economic conditions, including interest rates and inflation on the assumptions and estimates used when preparing its consolidated financial statements including, but not limited to, the allowance for doubtful accounts, valuation allowances, contract asset, and the recoverability of long-lived assets, goodwill and intangible assets. These assumptions and estimates may change as new events occur and additional information is obtained. If economic conditions worsen, such future changes may have an adverse impact on the Company's results of operations, financial position and liquidity. 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 September 30, 2023, consist primarily of cash and cash equivalents and accounts receivable, as disclosed in the consolidated balance sheet. Cash and cash equivalents are in excess of Federal Deposit Insurance Corporation insurance limits, but are maintained with quality financial institutions of high credit. The Company requires certain Network Partners to maintain security deposits with the Company, which, in the event of non-payment, would be applied against any accounts receivable outstanding. Due to the nature of the mortgage lending industry, interest rate fluctuations may negatively impact future revenue from the Company's marketplace. Lenders and lead purchasers participating on the Company's marketplace can offer their products directly to consumers through brokers, mass marketing campaigns or through other traditional methods of credit distribution. These lenders and lead purchasers can also offer their products online, either directly to prospective borrowers, through one or more online competitors, or both. If a significant number of potential consumers are able to obtain loans and other products from Network Partners without utilizing the Company's services, the Company's ability to generate revenue may be limited. Because the Company does not have exclusive relationships with the Network Partners whose loans and other financial products are offered on its online marketplace, consumers may obtain offers from these Network Partners without using its service. Other than a support services office in India, the Company's operations are geographically limited to and dependent upon the economic condition of the United States. Litigation Settlements and Contingencies Litigation settlements and contingencies consists of expenses related to actual or anticipated litigation settlements. Recently Adopted Accounting Pronouncements In August 2020, the Financial Accounting Standards Board issued Accounting Standards Update ("ASU") 2020-06, which simplifies the accounting for convertible instruments, amends the derivatives scope exception guidance for contracts in an entity’s own equity, and amends the related earnings-per-share guidance. Under the new guidance, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. As a result, a convertible debt instrument will be accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. The Company adopted ASU 2020-06 on January 1, 2022 using the modified retrospective transition approach and recognized the cumulative effect of initially applying ASU 2020-06 as a $44.4 million adjustment to the opening balance of accumulated deficit, comprised of $60.8 million for the interest adjustment, net of $16.4 million for the related tax impacts. The recombination of the equity conversion component of the Company's convertible debt remaining outstanding caused a reduction in additional paid-in capital and an increase in deferred income tax assets. The removal of the remaining debt discounts recorded for this previous separation had the effect of increasing our net debt balance. ASU 2020-06 also requires the dilutive impact of convertible debt instruments to utilize the if-converted method when calculating diluted earnings per share and the result is more dilutive. The adoption of ASU 2020-06 did not impact the Company's cash flows or compliance with debt covenants. Recently Issued Accounting Pronouncements The Company has considered the applicability of recently issued accounting pronouncements by the Financial Accounting Standards Board and have determined that they are either not applicable or are not expected to have a material impact on the Company's consolidated financial statements.
