Accounting Estimates	Accounting Estimates Management of the Company is required to make certain estimates, judgments and assumptions during the preparation of its consolidated financial statements in accordance with GAAP. These estimates, judgments and assumptions impact the reported amounts of assets, liabilities, revenue and expenses and the related disclosure of contingent assets and liabilities. Actual results could differ from these estimates. On an ongoing basis, the Company evaluates its estimates and judgments, including those related to: the fair values of cash equivalents; the carrying value of accounts receivable, including the determination of the allowance for credit losses; the determination of revenue reserves; the carrying value of right-of-use assets ("ROU assets"); the useful lives and recoverability of definite-lived intangible assets and capitalized software, leasehold improvements and equipment; the recoverability of goodwill and indefinite-lived intangible assets; unrecognized tax benefits; the valuation allowance for deferred income tax assets; and the fair value of and forfeiture rates for stock-based awards, among others. The Company bases its estimates and judgments on historical experience, its forecasts and budgets and other factors that the Company considers relevant.
General Revenue Recognition	General Revenue Recognition Revenue is recognized when control of the promised services or goods is transferred to the Company's customers and in the amount that reflects the consideration the Company expects to be entitled to in exchange for those services or goods. The Company's disaggregated revenue disclosures are presented in "Note 7—Segment Information." Prior to January 1, 2020, Handy recorded revenue on a net basis. Effective January 1, 2020, the Company modified the Handy terms and conditions so that Handy, rather than the service professional, has the contractual relationship with the consumer to deliver the service and Handy, rather than the consumer, has the contractual relationship with the service professional. Consumers request services and pay for such services directly through the Handy platform and then Handy fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. This change in contractual terms requires gross revenue accounting treatment effective January 1, 2020. Also, in the case of certain tasks, HomeAdvisor provides a pre-priced product offering, pursuant to which consumers can request services through a HomeAdvisor platform and pay HomeAdvisor for the services directly. HomeAdvisor then fulfills the request with independently established home services providers engaged in a trade, occupation and/or business that customarily provides such services. Revenue from HomeAdvisor’s pre-priced product offering is also recorded on a gross basis effective January 1, 2020. In addition to changing the presentation of revenue to gross from net, the timing of revenue recognition changed for HomeAdvisor pre-priced jobs and will be later than consumer connection revenue because the Company will not be able to record revenue, generally, until the service professional completes the job on the Company's behalf. The change to gross revenue reporting for Handy and HomeAdvisor’s pre-priced product offering, effective January 1, 2020, resulted in an increase in revenue of $20.8 million and $51.3 million during the three and nine months ended September 30, 2020, respectively. Deferred Revenue Deferred revenue consists of payments that are received or are contractually due in advance of the Company's performance. The Company’s deferred revenue is reported on a contract by contract basis at the end of each reporting period. The Company classifies deferred revenue as current when the term of the applicable subscription period or expected completion of the Company's performance obligation is one year or less. The current and non-current deferred revenue balances at December 31, 2019 were $58.2 million and $0.2 million, respectively. During the nine months ended September 30, 2020, the Company recognized $55.7 million of revenue that was included in the deferred revenue balance as of December 31, 2019. During the nine months ended September 30, 2019, the Company recognized $58.5 million of revenue that was included in the deferred revenue balance as of December 31, 2018. The current and non-current deferred revenue balances at September 30, 2020 are $58.2 million and $0.1 million, respectively. Non-current deferred revenue is included in “Other long-term liabilities” in the accompanying consolidated balance sheet. Practical Expedients and Exemptions As permitted under the practical expedient available under Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers, the Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts with variable consideration that is allocated entirely to unsatisfied performance obligations or to a wholly unsatisfied promise accounted for under the series guidance, and (iii) contracts for which the Company recognizes revenue at the amount which the Company has the right to invoice for services performed. For sales incentive programs where the customer relationship period is one year or less, the Company has elected the practical expedient to expense the costs as incurred.
Adoption of New Accounting Pronouncements	Adoption of New Accounting Pronouncements Adoption of ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments The Company adopted ASU No. 2016-13 effective January 1, 2020. ASU No. 2016-13 replaces the “incurred loss” approach with an “expected loss” model, under which companies will recognize allowances based on expected rather than incurred losses. The Company adopted ASU No. 2016-13 using the modified retrospective approach and there was no cumulative effect arising from the adoption. The adoption of ASU No. 2016-13 did not have a material impact on the Company's consolidated financial statements. Adoption of ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes The Company adopted ASU No. 2019-12 effective January 1, 2020, which simplifies the accounting for income taxes, eliminates certain exceptions within ASC 740, Income Taxes, and clarifies certain aspects of the current guidance to promote consistency among reporting entities. Most amendments within ASU No. 2019-12 are required to be applied on a prospective basis, while certain amendments must be applied on a retrospective or modified retrospective basis. The Company adopted ASU No. 2019-12 on January 1, 2020 using the modified retrospective basis for those amendments that are not applied on a prospective basis. The adoption of ASU No. 2019-12 did not have a material impact on the Company’s consolidated financial statements.
