Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Preparation The accompanying consolidated financial statements, which include the accounts of Holdings and its subsidiaries, have been prepared using accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany transactions were eliminated on consolidation. Although the Company believes the disclosures included herein are adequate to ensure that the consolidated financial statements are fairly presented, certain information and footnote disclosures to the financial statements have been condensed or omitted in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, the consolidated financial statements and the footnotes included herein should be read in conjunction with the audited financial statements and the footnotes included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2018. Segment Information Operating segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker ("CODM"). The Company has determined that its chief executive officer is the Company's CODM. The Company has identified three reportable segments: web presence, domains and email marketing. The Company has determined that it does not satisfy aggregation criteria for these operating segments, and that each segment meets the quantitative threshold of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 280, Segment Reporting . Therefore, all three operating segments are reportable segments. The Company's segments share certain resources, primarily related to sales and marketing, engineering and development, and general and administrative functions. Management allocates these costs to each respective segment based on a consistently applied methodology, primarily based on a percentage of revenue. Use of Estimates U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates, judgments and assumptions used in preparing the accompanying consolidated financial statements are based on the relevant facts and circumstances as of the date of the consolidated financial statements. Although the Company regularly assesses these estimates, judgments and assumptions used in preparing the consolidated financial statements, actual results could differ from those estimates. Changes in estimates are recorded in the period in which they become known. The more significant estimates reflected in these consolidated financial statements include estimates of fair value of assets acquired and liabilities assumed under purchase accounting related to the Company’s acquisitions and when evaluating goodwill and long-lived assets for potential impairment, the estimated useful lives of intangible and depreciable assets, revenue recognition for multiple-element arrangements, stock-based compensation, contingent consideration, derivative instruments, certain accruals, reserves and deferred taxes. Unaudited Interim Financial Information The accompanying interim consolidated balance sheet as of September 30, 2019 , and the related consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 2018 and 2019 , the consolidated statements of cash flows for the nine months ended September 30, 2018 and 2019 , the consolidated statements of changes in stockholders' equity for the three and nine months ended September 30, 2018 and 2019 , and the notes to consolidated financial statements are unaudited. These unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements. The unaudited consolidated financial statements include, in the opinion of management, all adjustments, consisting only of normal recurring adjustments that are necessary for a fair presentation of the Company’s financial position as of September 30, 2019 , results of operations for the three and nine months ended September 30, 2018 and 2019 , cash flows for the nine months ended September 30, 2018 and 2019 , and changes in stockholders' equity for the three and nine months ended September 30, 2018 and 2019 . The results in the consolidated statements of operations and comprehensive income (loss) are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2019 . Cash Equivalents Cash and cash equivalents include all highly liquid investments with remaining maturities of three months or less at the date of purchase. Restricted Cash Restricted cash is composed of certificates of deposit and cash held by merchant banks and payment processors, which provide collateral against any chargebacks, fees, or other items that may be charged back to the Company by credit card companies and other merchants, and collateral for certain facility leases. Accounts Receivable Accounts receivable is primarily composed of cash due from credit card companies for unsettled transactions charged to customers’ credit cards. As these amounts reflect authenticated transactions that are fully collectible, the Company does not maintain an allowance for doubtful accounts. The Company also accrues for earned referral fees and commissions, which are governed by reseller or affiliate agreements, when the amount is reasonably estimable. Prepaid Domain Name Registry Fees Prepaid domain name registry fees represent amounts that are paid in full at the time a domain is registered by one of the Company’s registrars on behalf of a customer. The registry fees are recognized on a straight-line basis over the term of the domain registration period. Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include cash equivalents, accounts receivable, accounts payable and certain accrued expenses, approximate their fair values due to their short maturities. The fair value of the Company's notes payable is based on the borrowing rates currently available to the Company for debt with similar terms and average maturities and approximates their carrying value. Derivative Instruments and Hedging Activities FASB ASC 815, Derivatives and Hedging , provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit risk-related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the FASB’s fair value measurement guidance in FASB Accounting Standards Update ("ASU") No. 2011-4, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio. Property and Equipment Property and equipment is recorded at cost, or at fair value if the property and equipment is acquired in an acquisition. The Company also capitalizes the direct costs of constructing additional computer equipment for internal use, as well as upgrades to existing computer equipment which extend the useful life, capacity or operating efficiency of the equipment. Capitalized costs include the cost of materials, shipping and taxes. Materials used for repairs and maintenance of computer equipment are expensed and recorded as a cost of revenue. Materials on hand and construction-in-process are recorded as property and equipment. Assets recorded under equipment financing are depreciated over the lease term. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets as follows: Building Thirty-five years Software Two to three years Computers and office equipment Three years Furniture and fixtures Five years Leasehold improvements Shorter of useful life or remaining term of the lease Software Development Costs The Company accounts for software development costs for internal-use software under the provisions of FASB ASC 350-40, Internal-Use Software. Accordingly, certain costs to develop internal-use computer software are capitalized, provided these costs are expected to be recoverable. During the three and nine months ended September 30, 2018 , the Company capitalized internal-use software development costs of $2.8 million and $7.1 million , respectively. During the three and nine months ended September 30, 2019 , the Company capitalized internal-use software development costs of $3.8 million and $11.1 million , respectively. Goodwill Goodwill relates to amounts that arose in connection with the Company’s various business combinations and represents the difference between the purchase price and the fair value of the identifiable intangible and tangible net assets when accounted for using the purchase method of accounting. Goodwill is not amortized, but is subject to periodic review for impairment. Events that would indicate impairment and trigger an interim impairment assessment include, but are not limited to, current economic and market conditions, including a decline in the equity value of the Company's business, a significant adverse change in agreements that would materially affect reported operating results, business climate or operational performance of the business and an adverse action or assessment by a regulator. Additionally, a reorganization or change in the number of reporting units could result in the reassignment of goodwill between reporting units and may trigger an impairment assessment. In accordance with ASU No. 2011-08, Intangibles—Goodwill and Other (Topic 350) , the Company is required to review goodwill by reporting unit for impairment at least annually or more often if there are indicators of impairment present. Under U.S. GAAP, a reporting unit is either the equivalent of, or one level below, an operating segment. The Company performs its annual goodwill test as of October 31 of each fiscal year. The Company has identified a total of ten reporting units, and goodwill has been allocated to six of these reporting units. The Company also early adopted the provisions of ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) , which eliminates the second step of the goodwill impairment test. As a result, the Company's goodwill impairment test includes only one step, which is a comparison of the carrying value of each reporting unit to its fair value, and any excess carrying value, up to the amount of goodwill allocated, is impaired. Goodwill has been allocated to each reporting unit in accordance with ASC 350-20-40, which requires that goodwill be allocated based on the relative fair values of each reporting unit. The carrying value of each reporting unit is based on the assignment of the appropriate assets and liabilities to each reporting unit. Assets and liabilities are assigned to each reporting unit if the assets or liabilities are employed in the operations of the reporting unit and the asset and liability is considered in the determination of the reporting unit's fair value. Certain assets and liabilities are shared by multiple reporting units, and are allocated to each reporting unit based on its relative size, primarily based on revenue. The fair value of each reporting unit is determined by the income approach and the market approach. For the income approach, fair value is determined based on the present value of estimated future after-tax cash flows, discounted at an appropriate risk adjusted rate. The Company derives its discount rates using a capital asset pricing model and by analyzing published rates for industries relevant to the reporting units to estimate the weighted-average cost of capital. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the business and in internally developed forecasts. For fiscal year 2018, the Company used a discount rate of 10.0% for all but one of its reporting units. The Company also performed sensitivity analysis on its discount rates. The Company uses internal forecasts to estimate future after-tax cash flows, which include an estimate of long-term future growth rates based on the Company's view of the long-term outlook for each reporting unit. Actual results may differ from those assumed in the Company's forecasts. For the market approach, the Company utilizes two different approaches: market multiples for publicly traded companies, and market multiples based on the acquisition value of comparable companies that were sold. For the fiscal year 2018 goodwill impairment analysis, the Company compared the fair value from the income approach to the two market approaches. For three of the Company's reporting units, which represent approximately 95% of the Company's goodwill, the fair value derived from the income approach was consistent with the fair value derived from the two market approaches. The Company established the fair value for these reporting units based on the average fair value from all three valuation approaches. For two of the Company's reporting units, which represent approximately 3% of the Company's goodwill, the Company based their fair value entirely upon the income approach, as these two reporting units are experiencing declining cash flows and are expected to continue to experience declines over time. The fair values from the income approach for these two reporting units were materially below the fair values derived from both market approaches. The goodwill allocated to these two reporting units is approximately $64.2 million as of December 31, 2018. Although the Company does not expect an impairment of goodwill for these two reporting units in the near term, the Company expects that cash flows will continue to decline, which could result in goodwill impairment charges for these two reporting units at some point in the future. For one of the reporting units, which represents approximately 2% of the Company's goodwill, the fair values derived from the market approaches were much lower than the income approach using a discount rate of 10% . The Company determined that more risk was present in the projected future cash flows of this reporting unit as compared to the Company's other reporting units and determined that a discount rate of 17% was appropriate. The fair value of this reporting unit under the income approach at a discount rate of 17% was consistent with the fair values determined under the two market approaches. The Company established fair value for this reporting unit based on the average fair value from all three valuation approaches. As of the test date of October 31, 2018, the fair value for all reporting units was higher than their respective carrying values, and no impairment has been recorded. No triggering events were identified between the October 31, 2018 test and December 31, 2018 . Goodwill as of December 31, 2018 was $1,849.1 million . The carrying value of goodwill that was allocated to the domain, email marketing and web presence reporting segments was approximately $29.9 million , $604.3 million and $1,214.9 million , respectively. The fair value of all reporting units with goodwill at December 31, 2018 exceeded each reporting unit's carrying value by at least 20% . Goodwill as of September 30, 2019 was $1,854.8 million . The carrying value of goodwill that was allocated to the domain, email marketing and web presence reporting segments was approximately $ 29.9 million , $611.3 million and $1,213.7 million , respectively. For the three and nine months ended September 30, 2019 , no impairment triggering events were identified and no impairment has been recorded. Long-Lived Assets The Company’s long-lived assets consist primarily of intangible assets, including acquired subscriber relationships, trade names, intellectual property, developed technology and domain names available for sale. The Company also has long-lived tangible assets, primarily consisting of property and equipment. The majority of the Company’s intangible assets are recorded in connection with its various acquisitions. The Company’s intangible assets are recorded at fair value at the time of their acquisition. The Company amortizes intangible assets over their estimated useful lives. Determination of the estimated useful lives of the individual categories of intangible assets is based on the nature of the applicable intangible asset and the expected future cash flows to be derived from the intangible asset. Amortization of intangible assets with finite lives other than developed technology is recognized in accordance with their estimated projected cash flows. The Company evaluates long-lived intangible and tangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If indicators of impairment are present and undiscounted future cash flows are less than the carrying amount, the fair value of the assets is determined and compared to the carrying value. If the fair value is less than the carrying value, then the carrying value of the asset is reduced to the estimated fair value and an impairment loss is charged to expense in the period the impairment is identified. Indefinite life intangible assets include domain names that are available for sale which are recorded at the cost to acquire. These assets are not being amortized and are being tested for impairment annually and whenever events or changes in circumstance indicate that their carrying value may not be recoverable. When a domain name is sold, the Company records the cost of the domain in cost of revenue. During the three and nine months ended September 30, 2019 , the Company recognized an impairment charge of $0.0 million and $17.9 million , respectively, relating primarily to premium domain name intangible assets acquired in 2014, which was recorded in cost of revenue in the consolidated statements of operations and comprehensive income (loss). The impairment resulted from recent market conditions that have adversely impacted cash flows from these assets, and these market conditions are expected to continue. The Company valued its premium domain name assets based on discounted projected cash flows from these assets using a discount rate of 11.6% , which resulted in an impairment of $16.2 million during the three months ended June 30, 2019. The balance of the impairment charge was primarily related to developed technology intangible assets associated with the premium domain business, which were valued using a relief from royalty approach. During the three and nine months ended September 30, 2018 , the Company recorded no impairment charge associated with these intangible assets. Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , or ASC 606, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. Since then, the FASB has also issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations, ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing, and ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606) , Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments , which further elaborate on the original ASU No. 2014-09. The Company adopted the guidance in ASC 606 on January 1, 2018. Revenue is recognized when control of the promised products or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to for those products and services. In general, the Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with the customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, the Company satisfies a performance obligation The Company provides cloud-based subscription services, which include web hosting and related add-ons, search engine optimization ("SEO") services, domain registration services and email marketing. Web hosting gives customers access to an environment where the Company hosts a customer’s website. The related contract terms are generally for one year , but can range from 30 days to three years . Web hosting services are typically sold in bundled offerings that include web hosting, domain registration services and various add-ons. The Company recognizes revenue for web hosting and domain registration services over the term of the contract. The main add-on services related to web hosting are domain privacy, website security, secure sockets layer security, site backup and restoration, and web builder tools. These services may be included in web hosting bundles, or they may be purchased on a standalone basis. Certain add-on services are provided by third parties. In cases where the Company is acting as an agent for the sale of third-party add-on services, the Company recognizes revenue on a net basis at the time of sale. In cases where the Company is acting as a principal for the sale of third-party add-on services (i.e., the Company has the primary responsibility to provide specific goods or services, it has discretion to establish prices and it may assume inventory risk), the Company recognizes revenue on a gross basis over the term of the contract. The revenue for Company-provided add-on services is primarily recognized over the term of the contract. SEO services are monthly subscriptions that provide a customer with increased traffic to their website over the term of the subscription. Revenue from SEO services is recognized over the monthly term of the contract. In the case of domain registration services, the Company is an accredited registrar and can provide registration services to the customer, or it can select an accredited third-party registrar to perform these duties. Domain registration services are generally annual subscriptions, but can cover multiple years. Revenue for these services is recognized over the life of the subscription. Email marketing services provide customers with a cloud-based platform that can send broadcast emails to a contact list managed by the customer. Pricing is based on contact list volume from the prior monthly period, which determines the contractual billing price for the upcoming month. Revenue for this service is recognized over the monthly term of the contract. Inventory management and marketplace listing services provide customers with a cloud-based platform that integrates standard inventory management features with order management and shipping management capabilities across multiple channels. Pricing is primarily based on order volume from the prior monthly period. For inventory management customers who subscribe to an annual plan, revenue is recognized ratably over the term of the contract. Inventory management professional services are also provided to customers on demand, and are recognized into revenue upon completion. Non-subscription-based services include certain professional services, primarily website design or re-design services, marketing development fund ("MDF") revenue, premium domain names and domain parking services. Website design and re-design services are recognized when the service is complete. Marketing development funds consist of commissions earned by the Company when a third party sells its products or services directly to the Company’s customers, and advertising revenue for third-party ads placed on Company websites. The Company records revenue when the service is provided and calculates it based on the contractual revenue share arrangement or over the term of the advertisement. Domain parking allows the Company to monetize certain of its premium domain names by loaning them to specialized third parties that generate advertising revenue from these parked domains on a pay-per-click basis. Revenue is recognized when earned and calculated based on the revenue share arrangement with the third party. Revenue from the sale of premium domains is recognized when persuasive evidence of an arrangement to sell such domains exists and delivery of an authorization key to access the domain name has occurred. Premium domain names are paid for in advance prior to the delivery of the domain name. The contracts that the Company enters into typically do not contain any variable or non-cash considerations. The Company maintains a reserve for refunds and chargebacks related to revenue that has been recognized and is expected to be refunded, as calculated based on observed historical trends. The Company had a refund and chargeback reserve of $0.4 million and $0.3 million as of December 31, 2018 and September 30, 2019 , respectively. The portion of deferred revenue that was expected to be refunded at December 31, 2018 and September 30, 2019 was $2.2 million and $1.7 million , respectively. Based on refund history, approximately 83% of all refunds happen in the same fiscal month that the contract starts or renews, and approximately 95% of all refunds happen within 45 days of the contract start or renewal date. The Company did not apply any practical expedients during its adoption of ASC 606. The Company elected to use the portfolio method in the calculation of the deferred contract assets. Contracts with Multiple Performance Obligations A considerable amount of the Company’s revenue is generated from transactions that are contracts with customers that may include web hosting plans, domain name registrations, and other cloud-based products and services. In these cases, the Company determines whether the products and services are distinct performance obligations that should be accounted for separately versus together. The Company allocates revenue to each performance obligation based on its relative standalone selling price ("SSP"), generally based on the price charged to customers. Web hosting services, domain name registrations, and other cloud-based products and services have distinct performance obligations and are often sold separately. If the promise is not distinct and therefore not a performance obligation, then the total transaction amount is allocated to the identified performance obligation based on a relative selling price hierarchy. When multiple performance obligations are included in a contract, the total transaction amount for the contract is allocated to the performance obligations based on a relative selling price hierarchy. The Company determines the relative selling price for a performance obligation based on SSP. The Company determines SSP by considering its observed SSPs, competitive prices in the marketplace and management judgment; these SSPs may vary depending upon the particular facts and circumstances related to each deliverable. The Company analyzes the SSPs used in its allocation of transaction amount, at a minimum, on a quarterly basis. Deferred Revenue The Company records deferred revenue when cash payments are received or are due in advance of the Company’s performance, including amounts that are refundable. The following table provides a reconciliation of the Company's deferred revenue as of September 30, 2019 : Short-term Long-term (in thousands) Balance at December 31, 2018 $ 371,758 $ 96,140 Recognition of beginning deferred revenue into revenue, as a result of performance obligations satisfied (323,934 ) — Cash received in advance during the period 652,151 191,750 Recognition of cash received in the period into revenue, as a result of performance obligations satisfied (512,146 ) — Impact of foreign exchange rates (733 ) — Reclassification between short-term and long-term 188,633 (188,633 ) Balance at September 30, 2019 $ 375,729 $ 99,257 The difference between the opening and closing balances of the Company’s deferred revenue liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. During the nine months ended September 30, 2019 , the Company recognized $323.9 million and $0.0 million , respectively, from beginning deferred revenue current and long-term balances existing at December 31, 2018 . The Company did not recognize any revenue from performance obligations satisfied in prior periods. The following table provides the remaining performance obligation amounts as of September 30, 2019 . These amounts are equivalent to the ending deferred revenue balance of $475.0 million , which includes both short and long-term amounts: Web presence Email marketing Domain Total (in thousands) Remaining performance obligation, short-term $ 260,679 $ 55,983 $ 59,067 $ 375,729 Remaining performance obligation, long-term 84,161 4 15,092 99,257 Total $ 344,840 $ 55,987 $ 74,159 $ 474,986 This backlog of revenue related to future performance obligations is prepaid by customers and supported by executed contracts with customers. The Company has established a reserve of $0.3 million for refunds and chargebacks, 95% of which is expected to materialize in the first 45 days after the contract start date or renewal date. The remainder of the deferred revenue is expected to be recognized in future periods. Deferred Customer Acquisition Costs As a result of the implementation of ASC 606, the Company now capitalizes the incremental costs directly related to obtaining and fulfilling a contract (such as sales commissions and certain direct sales and marketing success-based costs), if these costs are expected to be recovered. These costs are amortized over the period the services are transferred to the customer, which is estimated based on customer churn rates for various segments of the business. The Company includes only those incremental costs that would not have been incurred if the contracts had not been entered into: Short-term Long-term (

Business Combinations [Abstract]
Acquisitions	Acquisitions The Company accounts for the acquisitions of businesses using the purchase method of accounting. The Company allocates the purchase price to the tangible and identifiable intangible assets and liabilities assumed based on their estimated fair values. Purchased identifiable intangible assets typically include subscriber relationships, trade names, domain names held for sale, developed technology and in-process research and development. The methodologies used to determine the fair value assigned to subscriber relationships and domain names held for sale are typically based on the excess earnings method that considers the return received from the intangible asset and includes certain expenses and also considers an attrition rate based on the Company’s internal subscriber analysis and an estimate of the average life of the subscribers. The fair value assigned to trade names is typically based on the income approach using a relief from royalty methodology that assumes that the fair value of a trade name can be measured by estimating the cost of licensing and paying a royalty fee for the trade name that the owner of the trade name avoids. The fair value assigned to developed technology typically uses the cost approach. If applicable, the Company estimates the fair value of contingent consideration payments in determining the purchase price. The contingent consideration is then adjusted to fair value in subsequent periods as an increase or decrease in current earnings in general and administrative expense in the consolidated statements of operations and comprehensive income (loss). Ecomdash On September 13, 2019, the Company acquired substantially all of the assets of LTD Software LLC, doing business as Ecomdash (“Ecomdash”), which is a software provider that offers inventory management and marketplace listing solutions for small and mid-sized businesses selling online. The aggregate purchase price was $9.6 million , of which approximately $8.9 million was paid in cash at the closing. The Company retained the remainder of the purchase price as a holdback t o fund any working capital adjustment, if applicable, and to serve as security for the indemnification obligations of the seller under the asset purchase agreement . Subject to any working capital adjustment and indemnification claims, the Company will release the holdback funds to the seller 12 months from the closing date. Transaction costs were expensed as incurred. The Company has accounted for this transaction as a business combination in accordance with the acquisition method of accounting, which requires, among other things, that assets acquired and liabilities assumed be recognized at their estimated fair values as of the acquisition date. The following table summarizes the preliminary allocation of the purchase consideration to the assets acquired and liabilities assumed at the date of acquisition: September 13, 2019 (in thousands) Working capital $ (163 ) Goodwill 6,953 Developed technology 2,445 Subscriber relationships 390 Total $ 9,625 Goodwill related to the acquisition is deductible for tax purposes.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements The following valuation hierarchy is used for disclosure of the valuation inputs used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows: • Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities • Level 2 inputs are quoted prices for similar assets or liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument • Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. As of December 31, 2018 , the Company’s financial assets required to be measured on a recurring basis consisted of the 2015 interest rate cap, the 2018 interest rate cap, and certain cash equivalents, which included money market instruments and bank time deposits. As of September 30, 2019 , the Company’s financial assets required to be measured on a recurring basis consist of the 2018 interest rate cap and certain cash equivalents, which include money market instruments and bank time deposits. The Company has classified the interest rate caps, which are discussed in Note 7 , Derivatives and Hedging Activities below, within Level 2 of the fair value hierarchy. The Company has also classified these cash equivalents within Level 2 of the fair value hierarchy. The 2015 interest rate cap matured during the three months ended March 31, 2019.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	Derivatives and Hedging Activities Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk primarily by managing the amount, sources, and duration of its debt funding and the use of derivative financial instruments. Specifically, the Company may enter into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to the Company’s investments and borrowings. Cash Flow Hedges of Interest Rate Risk The Company has entered into two three -year interest rate caps as part of its risk management strategy, of which the first one matured in the three months ended March 31, 2019. The interest rate caps, designated as cash flow hedges of interest rate risk, provide for the payment to the Company of variable amounts if interest rates rise above the strike rate on the contract in exchange for an upfront premium. Therefore, these derivatives limit the Company’s exposure if the interest rate rises, but also allow the Company to benefit when the interest rate falls.

Revenue from Contract with Customer [Abstract]
Revenue	Revenue Adoption of ASC 606, Revenue from Contracts with Customers The Company recorded a net increase to opening retained earnings of $59.4 million as of January 1, 2018 due to the cumulative impact of adopting ASC 606, with the impact primarily related to customer acquisition costs. During the three months ended September 30, 2018 and 2019 , the Company recognized $283.8 million and $277.2 million of revenue, respectively, the majority of which was derived from contracts with customers. During the nine months ended September 30, 2018 and 2019 , the Company recognized $862.9 million and $836.1 million of revenue, respectively, the majority of which was derived from contracts with customers. During the three and nine months ended September 30, 2018 and 2019 , the Company did not incur any impairment or credit losses on any receivables or contract assets arising from the Company’s contracts with customers. In accordance with ASC 606, the Company disaggregates revenue from contracts with customers based on the timing of revenue recognition.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended September 30, 2018 and 2019 , the Company recognized a tax expense of $11.7 million and a tax benefit of $4.8 million , respectively, in the consolidated statements of operations and comprehensive income (loss). For the nine months ended September 30, 2018 and 2019 , the Company recognized a tax expense of $8.8 million and $3.0 million , respectively, in the consolidated statements of operations and comprehensive income (loss). The components of the expense (benefit) for income taxes consisted of the following: Three Months Ended September 30, Nine Months Ended September 30, 2018 2019 2018 2019 (in thousands) Current: U.S. Federal and State $ 118 $ (3,254 ) $ 536 $ 599 Foreign (1,620 ) (1,091 ) (756 ) 499 Total current (benefit) expense (1,502 ) (4,345 ) (220 ) 1,098 Deferred: U.S. Federal and State 12,940 (580 ) 8,883 1,986 Foreign 277 86 163 (44 ) Total deferred expense (benefit) 13,217 (494 ) 9,046 1,942 Total expense (benefit) $ 11,715 $ (4,839 ) $ 8,826 $ 3,040 The expense (benefit) for income taxes shown on the consolidated statements of operations and comprehensive income (loss) differs considerably from amounts that would result from applying the statutory tax rates to income before taxes primarily due to tax rules and attributes that are available to each of the jurisdictions in which the Company operates. In addition, due to the recent changes in U.S. tax law based on the TCJA, there are a number of provisions that impact the Company’s overall tax result, a significant item being the limitation on the deductibility of interest expenses. These new laws may create variability from period to period, especially when the Company is assessing whether its deferred tax assets and liabilities are more likely than not to be realized. The Company is required to assess its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive and negative evidence, and weighted the evidence based on its objectivity. Evidence the Company considered included: • NOLs incurred from the Company’s inception to date • Expiration of various federal, state and foreign tax attributes • Reversals of existing temporary differences • Composition and cumulative amounts of existing temporary differences and • Current year forecasted profit before tax After consideration of all positive and negative evidence, the Company believes that it is more likely than not that a portion of its deferred tax assets will not be realized. The Company has recorded a valuation allowance at December 31, 2018 and September 30, 2019 of $47.1 million and $64.0 million , respectively. The increase in valuation allowance is primarily due to the change in the timing of when the existing temporary differences are expected to reverse in the future. The Company establishes reserves when the Company believes that certain positions are likely to be challenged despite the Company’s assertion that its tax return positions are fully supportable. The calculation of the Company’s tax liabilities involves significant judgment based on individual facts, circumstances and information available in addition to applying complex tax regulations in various jurisdictions. The Company recognizes, in its consolidated financial statements, the effect of a tax position when it is more likely than not, based on the technical merits, that the position will be sustained upon examination. The Company has recorded unrecognized tax benefits at December 31, 2018 and September 30, 2019 of $4.4 million and $3.7 million , respectively, that would affect its effective tax rate. The Company does not expect a significant change in the liability for unrecognized tax benefits in the next 12 months. As of December 31, 2018 , the Company had recorded the following tax attributes available to be carried forward: Jurisdiction Amount Year Loss Carry-forwards Expire (in millions) Domestic Federal $ 108.9 2037 State 115.5 various dates through 2038 Foreign China 0.9 2021 Netherlands 12.1 2020 India 0.6 2020 Singapore 0.3 indefinite Total NOL carry-forwards $ 238.3 Domestic Federal $ 29.2 2023 State 12.9 various dates through 2023 Total capital loss carry-forwards $ 42.1 Domestic Federal $ 23.7 2038 State 12.4 various dates through 2038 Total R&D credit carry-forwards $ 36.1 Total tax attributes available $ 316.5 As of December 31, 2018 and September 30, 2019 , the Company has recorded interest expense that can be carried forward indefinitely due to provisions of the TCJA, of $61.2 million and $139.8 million , respectively. The Company files income tax returns in the United States for federal income taxes and in various state jurisdictions. The Company also files in several foreign jurisdictions. In the normal course of business, the Company is subject to examination by tax authorities throughout the world. Since the Company is in a loss carry-forward position, it is generally subject to U.S. federal and state income tax examinations by tax authorities for all years for which a loss carry-forward is utilized.

These severance charges were associated with the elimination of approximately 660 positions, primarily in customer support. Additionally, the Company implemented additional restructuring plans to create operational efficiencies and synergies related to the Constant Contact acquisition, which resulted in additional severance charges for the elimination of approximately 50 positions. During the three and nine months ended September 30, 2019 , in connection with these plans (together, the “2017 Restructuring Plan”), the Company recorded severance charges of $0.0 million and $0.0 million and paid $0.1 million and $0.2 million , respectively.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies From time to time, the Company is involved in legal proceedings or subject to claims arising in the ordinary course of its business. The Company is not presently involved in any such legal proceeding or subject to any such claim that, in the opinion of its management, would have a material adverse effect on its business, operating results or financial condition. However, the results of such legal proceedings or claims cannot be predicted with certainty, and regardless of the outcome, can have an adverse impact on the Company because of defense and settlement costs, diversion of management resources and other factors. As previously disclosed, the Company was named as a defendant in two shareholder litigation matters, which are discussed below. Endurance On May 4, 2015, Christopher Machado, a purported holder of the Company’s common stock, filed a civil action in the United States District Court for the District of Massachusetts against the Company and its former chief executive officer and former chief financial officer, captioned Machado v. Endurance International Group Holdings, Inc., et al., Civil Action No. 1:15-cv-11775-GAO. The plaintiff filed an amended complaint on December 8, 2015, a second amended complaint on March 18, 2016, and a third amended complaint on June 30, 2017. In the third amended complaint, plaintiffs Christopher Machado and Michael Rubin alleged claims for violations of Section 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and Sections 11, 12(a)(2), and 15 of the Securities Act of 1933, as amended, on behalf of a purported class of purchasers of the Company’s securities between October 25, 2013 and December 16, 2015, including persons or entities who purchased or acquired the Company's shares pursuant or traceable to the registration statement and prospectus issued in connection with the Company's October 25, 2013 initial public offering. The plaintiffs challenged as false or misleading certain of the Company’s disclosures about the total number of subscribers, average revenue per subscriber, the number of customers paying over $500 per year for the Company’s products and services, and the average number of products sold per subscriber. The proceedings were stayed and the parties negotiated the terms and conditions of a stipulation and agreement of settlement and related papers, which, among other things, provided for the release of all claims asserted against the Company and its former chief executive officer and former chief financial officer. On September 13, 2019, the court entered an order granting final approval of the settlement and dismissed the case with prejudice. The Company's contribution to the settlement pool was equal to the $5.8 million it reserved for this matter during the year ended December 31, 2018. Constant Contact On February 9, 2016, the Company acquired all of the outstanding shares of common stock of Constant Contact. On August 7, 2015, a purported class action lawsuit, William McGee v. Constant Contact, Inc., et al., was filed in the United States District Court for the District of Massachusetts against Constant Contact and two of its former officers. An amended complaint, which named an additional former officer as a defendant, was filed December 19, 2016. The lawsuit asserts claims under Sections 10(b) and 20(a) of the Exchange Act, and is premised on allegedly false and/or misleading statements, and non-disclosure of material facts, regarding Constant Contact’s business, operations, prospects and performance during the proposed class period of October 23, 2014 to July 23, 2015. The parties mediated the claims on March 27, 2018, and as a result of that mediation reached an agreement in principle with the lead plaintiff to settle the action. The parties then negotiated the terms and conditions of a stipulation and agreement of settlement and related papers, which, among other things, provide for the release of all claims asserted against Constant Contact and its former officers. On May 18, 2018, the plaintiffs filed an unopposed motion seeking preliminary approval of the proposed settlement, certification of the proposed settlement class for settlement purposes only, and approval of notice to the settlement class. The court has not yet ruled on this motion but a hearing is scheduled for November 8, 2019. The Company's contribution to the settlement pool under this proposed settlement would be equal to the $1.5 million it reserved for this matter during the year ended December 31, 2018. The Company cannot make any assurances as to whether or when the McGee settlement will be approved by the court and the Company cannot assess the ultimate outcome of this matter or an estimate of any probable losses or any reasonably possible losses (other than the reserve specifically discussed above) at this time.

Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions The Company has various agreements in place with related parties. Below are details of significant related party transactions that occurred during the nine months ended September 30, 2018 and 2019 . Tregaron: The Company has contracts with Tregaron India Holdings, LLC and its affiliates, including Diya Systems (Mangalore) Private Limited, Glowtouch Technologies Pvt. Ltd. and Touchweb Designs, LLC (collectively, “Tregaron”), for outsourced services, including email- and chat-based customer and technical support, network monitoring, engineering and development support and web design and web building services, and an office space lease. As of December 31, 2018, these entities were owned directly or indirectly by family members of the Company’s former chief executive officer, who was also a holder of more than 5% of the Company's capital stock during the majority of the year ended December 31, 2018. During the last quarter of fiscal year 2018, the former chief executive officer divested shares of the Company's capital stock, reducing his ownership to under 5% . As a result, Tregaron is not a related party as of January 1, 2019 and, therefore, no related party transactions are reported with Tregaron for the three and nine months ended September 30, 2019 . The following table presents the amounts of related party transactions recorded in the consolidated statements of operations and comprehensive income (loss) for the periods presented relating to services provided by Tregaron and its affiliates under these agreements for the periods in 2018 during which Tregaron was a related party: Three Months Ended Nine Months Ended 2018 2019 2018 2019 (in thousands) Cost of revenue $ 3,330 $ — $ 10,555 $ — Sales and marketing 160 — 605 — Engineering and development 290 — 960 — General and administrative 20 — 65 — Total related party transaction expense, net $ 3,800 $ — $ 12,185 $ — As of December 31, 2018 , approximately $2.4 million was included in accounts payable and accrued expense relating to services provided by Tregaron. Innovative Business Services, LLC and SiteLock, LLC: The Company also has an agreement with SiteLock, LLC ("SiteLock"), a subsidiary of Innovative Business Services, LLC, which provides multi-layered third-party security and website performance applications that are sold by the Company. During the nine months ended September 30, 2019 , a director of the Company and the Company’s former chief executive officer, who was also a holder of more than 5% of the Company's capital stock during the majority of the year ended December 31, 2018, continued to hold a material financial interest in SiteLock. The Company records revenue on the sale of SiteLock products on a net basis, since the Company views SiteLock as the primary obligor to deliver these services. As a result, the revenue share paid by the Company to SiteLock is recorded as contra-revenue. Further, SiteLock pays the Company a fee on sales made by SiteLock directly to customers of the Company. The Company records these fees as revenue. The following table presents the amounts of related party transactions recorded in the consolidated statements of operations and comprehensive income (loss) for the periods presented relating to the Company's agreement with SiteLock: Three Months Ended Nine Months Ended 2018 2019 2018 2019 (in thousands) Revenue $ (1,430 ) $ (1,400 ) $ (4,075 ) $ (4,140 ) Revenue (contra) 1,800 1,190 6,140 5,180 Total related party transaction impact to revenue $ 370 $ (210 ) $ 2,065 $ 1,040 Cost of revenue 170 180 490 500 Total related party transaction expense, net $ 540 $ (30 ) $ 2,555 $ 1,540 As of December 31, 2018 and September 30, 2019 , approximately $0.2 million and $0.0 million , respectively, was included in prepaid expenses and other current assets relating to the Company’s agreement with SiteLock.

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2019
Accounting Policies [Abstract]
Basis of Preparation	Basis of Preparation The accompanying consolidated financial statements, which include the accounts of Holdings and its subsidiaries, have been prepared using accounting principles generally accepted in the United States of America (“U.S. GAAP”). All intercompany transactions were eliminated on consolidation.
Segment Information	Segment Information Operating segments are defined as components of an enterprise that engage in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker ("CODM"). The Company has determined that its chief executive officer is the Company's CODM. The Company has identified three reportable segments: web presence, domains and email marketing. The Company has determined that it does not satisfy aggregation criteria for these operating segments, and that each segment meets the quantitative threshold of Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") 280, Segment Reporting . Therefore, all three operating segments are reportable segments. The Company's segments share certain resources, primarily related to sales and marketing, engineering and development, and general and administrative functions. Management allocates these costs to each respective segment based on a consistently applied methodology, primarily based on a percentage of revenue.
Use of Estimates	Use of Estimates U.S. GAAP requires management to make certain estimates, judgments and assumptions that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. These estimates, judgments and assumptions used in preparing the accompanying consolidated financial statements are based on the relevant facts and circumstances as of the date of the consolidated financial statements. Although the Company regularly assesses these estimates, judgments and assumptions used in preparing the consolidated financial statements, actual results could differ from those estimates. Changes in estimates are recorded in the period in which they become known. The more significant estimates reflected in these consolidated financial statements include estimates of fair value of assets acquired and liabilities assumed under purchase accounting related to the Company’s acquisitions and when evaluating goodwill and long-lived assets for potential impairment, the estimated useful lives of intangible and depreciable assets, revenue recognition for multiple-element arrangements, stock-based compensation, contingent consideration, derivative instruments, certain accruals, reserves and deferred taxes.
Unaudited Interim Financial Information	Unaudited Interim Financial Information The accompanying interim consolidated balance sheet as of September 30, 2019 , and the related consolidated statements of operations and comprehensive income (loss) for the three and nine months ended September 30, 2018 and 2019 , the consolidated statements of cash flows for the nine months ended September 30, 2018 and 2019 , the consolidated statements of changes in stockholders' equity for the three and nine months ended September 30, 2018 and 2019 , and the notes to consolidated financial statements are unaudited. These unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements. The unaudited consolidated financial statements include, in the opinion of management, all adjustments, consisting only of normal recurring adjustments that are necessary for a fair presentation of the Company’s financial position as of September 30, 2019 , results of operations for the three and nine months ended September 30, 2018 and 2019 , cash flows for the nine months ended September 30, 2018 and 2019 , and changes in stockholders' equity for the three and nine months ended September 30, 2018 and 2019 . The results in the consolidated statements of operations and comprehensive income (loss) are not necessarily indicative of the results of operations to be expected for the full fiscal year ending December 31, 2019 .
Cash Equivalents	Cash Equivalents Cash and cash equivalents include all highly liquid investments with remaining maturities of three months or less at the date of purchase.
Restricted Cash	Restricted Cash Restricted cash is composed of certificates of deposit and cash held by merchant banks and payment processors, which provide collateral against any chargebacks, fees, or other items that may be charged back to the Company by credit card companies and other merchants, and collateral for certain facility leases.
Accounts Receivable	Accounts Receivable Accounts receivable is primarily composed of cash due from credit card companies for unsettled transactions charged to customers’ credit cards. As these amounts reflect authenticated transactions that are fully collectible, the Company does not maintain an allowance for doubtful accounts. The Company also accrues for earned referral fees and commissions, which are governed by reseller or affiliate agreements, when the amount is reasonably estimable.
Prepaid Domain Name Registry Fees	Prepaid Domain Name Registry Fees Prepaid domain name registry fees represent amounts that are paid in full at the time a domain is registered by one of the Company’s registrars on behalf of a customer. The registry fees are recognized on a straight-line basis over the term of the domain registration period.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts of the Company's financial instruments, which include cash equivalents, accounts receivable, accounts payable and certain accrued expenses, approximate their fair values due to their short maturities. The fair value of the Company's notes payable is based on the borrowing rates currently available to the Company for debt with similar terms and average maturities and approximates their carrying value.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities FASB ASC 815, Derivatives and Hedging , provides the disclosure requirements for derivatives and hedging activities with the intent to provide users of financial statements with an enhanced understanding of: (a) how and why an entity uses derivative instruments, (b) how the entity accounts for derivative instruments and related hedged items, and (c) how derivative instruments and related hedged items affect an entity’s financial position, financial performance, and cash flows. Further, qualitative disclosures are required that explain the Company’s objectives and strategies for using derivatives, as well as quantitative disclosures about the fair value of and gains and losses on derivative instruments, and disclosures about credit risk-related contingent features in derivative instruments. As required by ASC 815, the Company records all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain of its risks, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. In accordance with the FASB’s fair value measurement guidance in FASB Accounting Standards Update ("ASU") No. 2011-4, Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements, the Company made an accounting policy election to measure the credit risk of its derivative financial instruments that are subject to master netting agreements on a net basis by counterparty portfolio.
Property and Equipment	Property and Equipment Property and equipment is recorded at cost, or at fair value if the property and equipment is acquired in an acquisition. The Company also capitalizes the direct costs of constructing additional computer equipment for internal use, as well as upgrades to existing computer equipment which extend the useful life, capacity or operating efficiency of the equipment. Capitalized costs include the cost of materials, shipping and taxes. Materials used for repairs and maintenance of computer equipment are expensed and recorded as a cost of revenue. Materials on hand and construction-in-process are recorded as property and equipment. Assets recorded under equipment financing are depreciated over the lease term. Depreciation is computed using the straight-line method over the estimated useful lives of the related assets as follows: Building Thirty-five years Software Two to three years Computers and office equipment Three years Furniture and fixtures Five years Leasehold improvements Shorter of useful life or remaining term of the lease
Software Development Costs	Software Development Costs The Company accounts for software development costs for internal-use software under the provisions of FASB ASC 350-40, Internal-Use Software.
Goodwill	Goodwill Goodwill relates to amounts that arose in connection with the Company’s various business combinations and represents the difference between the purchase price and the fair value of the identifiable intangible and tangible net assets when accounted for using the purchase method of accounting. Goodwill is not amortized, but is subject to periodic review for impairment. Events that would indicate impairment and trigger an interim impairment assessment include, but are not limited to, current economic and market conditions, including a decline in the equity value of the Company's business, a significant adverse change in agreements that would materially affect reported operating results, business climate or operational performance of the business and an adverse action or assessment by a regulator. Additionally, a reorganization or change in the number of reporting units could result in the reassignment of goodwill between reporting units and may trigger an impairment assessment. In accordance with ASU No. 2011-08, Intangibles—Goodwill and Other (Topic 350) , the Company is required to review goodwill by reporting unit for impairment at least annually or more often if there are indicators of impairment present. Under U.S. GAAP, a reporting unit is either the equivalent of, or one level below, an operating segment. The Company performs its annual goodwill test as of October 31 of each fiscal year. The Company has identified a total of ten reporting units, and goodwill has been allocated to six of these reporting units. The Company also early adopted the provisions of ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350) , which eliminates the second step of the goodwill impairment test. As a result, the Company's goodwill impairment test includes only one step, which is a comparison of the carrying value of each reporting unit to its fair value, and any excess carrying value, up to the amount of goodwill allocated, is impaired. Goodwill has been allocated to each reporting unit in accordance with ASC 350-20-40, which requires that goodwill be allocated based on the relative fair values of each reporting unit. The carrying value of each reporting unit is based on the assignment of the appropriate assets and liabilities to each reporting unit. Assets and liabilities are assigned to each reporting unit if the assets or liabilities are employed in the operations of the reporting unit and the asset and liability is considered in the determination of the reporting unit's fair value. Certain assets and liabilities are shared by multiple reporting units, and are allocated to each reporting unit based on its relative size, primarily based on revenue. The fair value of each reporting unit is determined by the income approach and the market approach. For the income approach, fair value is determined based on the present value of estimated future after-tax cash flows, discounted at an appropriate risk adjusted rate. The Company derives its discount rates using a capital asset pricing model and by analyzing published rates for industries relevant to the reporting units to estimate the weighted-average cost of capital. The Company uses discount rates that are commensurate with the risks and uncertainty inherent in the business and in internally developed forecasts. For fiscal year 2018, the Company used a discount rate of 10.0% for all but one of its reporting units. The Company also performed sensitivity analysis on its discount rates. The Company uses internal forecasts to estimate future after-tax cash flows, which include an estimate of long-term future growth rates based on the Company's view of the long-term outlook for each reporting unit. Actual results may differ from those assumed in the Company's forecasts. For the market approach, the Company utilizes two different approaches: market multiples for publicly traded companies, and market multiples based on the acquisition value of comparable companies that were sold. For the fiscal year 2018 goodwill impairment analysis, the Company compared the fair value from the income approach to the two market approaches. For three of the Company's reporting units, which represent approximately 95% of the Company's goodwill, the fair value derived from the income approach was consistent with the fair value derived from the two market approaches. The Company established the fair value for these reporting units based on the average fair value from all three valuation approaches. For two of the Company's reporting units, which represent approximately 3% of the Company's goodwill, the Company based their fair value entirely upon the income approach, as these two reporting units are experiencing declining cash flows and are expected to continue to experience declines over time. The fair values from the income approach for these two reporting units were materially below the fair values derived from both market approaches. The goodwill allocated to these two reporting units is approximately $64.2 million as of December 31, 2018. Although the Company does not expect an impairment of goodwill for these two reporting units in the near term, the Company expects that cash flows will continue to decline, which could result in goodwill impairment charges for these two reporting units at some point in the future. For one of the reporting units, which represents approximately 2% of the Company's goodwill, the fair values derived from the market approaches were much lower than the income approach using a discount rate of 10% . The Company determined that more risk was present in the projected future cash flows of this reporting unit as compared to the Company's other reporting units and determined that a discount rate of 17% was appropriate. The fair value of this reporting unit under the income approach at a discount rate of 17% was consistent with the fair values determined under the two market approaches. The Company established fair value for this reporting unit based on the average fair value from all three valuation approaches. As of the test date of October 31, 2018, the fair value for all reporting units was higher than their respective carrying values, and no impairment has been recorded. No triggering events were identified between the October 31, 2018 test and December 31, 2018 .
Long-Lived Assets	Long-Lived Assets The Company’s long-lived assets consist primarily of intangible assets, including acquired subscriber relationships, trade names, intellectual property, developed technology and domain names available for sale. The Company also has long-lived tangible assets, primarily consisting of property and equipment. The majority of the Company’s intangible assets are recorded in connection with its various acquisitions. The Company’s intangible assets are recorded at fair value at the time of their acquisition. The Company amortizes intangible assets over their estimated useful lives. Determination of the estimated useful lives of the individual categories of intangible assets is based on the nature of the applicable intangible asset and the expected future cash flows to be derived from the intangible asset. Amortization of intangible assets with finite lives other than developed technology is recognized in accordance with their estimated projected cash flows. The Company evaluates long-lived intangible and tangible assets whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If indicators of impairment are present and undiscounted future cash flows are less than the carrying amount, the fair value of the assets is determined and compared to the carrying value. If the fair value is less than the carrying value, then the carrying value of the asset is reduced to the estimated fair value and an impairment loss is charged to expense in the period the impairment is identified. Indefinite life intangible assets include domain names that are available for sale which are recorded at the cost to acquire. These assets are not being amortized and are being tested for impairment annually and whenever events or changes in circumstance indicate that their carrying value may not be recoverable. When a domain name is sold, the Company records the cost of the domain in cost of revenue. During the three and nine months ended September 30, 2019 , the Company recognized an impairment charge of $0.0 million and $17.9 million , respectively, relating primarily to premium domain name intangible assets acquired in 2014, which was recorded in cost of revenue in the consolidated statements of operations and comprehensive income (loss). The impairment resulted from recent market conditions that have adversely impacted cash flows from these assets, and these market conditions are expected to continue. The Company valued its premium domain name assets based on discounted projected cash flows from these assets using a discount rate of 11.6% , which resulted in an impairment of $16.2 million during the three months ended June 30, 2019. The balance of the impairment charge was primarily related to developed technology intangible assets associated with the premium domain business, which were valued using a relief from royalty approach. During the three and nine months ended September 30, 2018 , the Company recorded no impairment charge associated with these intangible assets.
Revenue Recognition	Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) , or ASC 606, which supersedes nearly all existing revenue recognition guidance under U.S. GAAP. Since then, the FASB has also issued ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606), Principal versus Agent Considerations, ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606), Identifying Performance Obligations and Licensing, and ASU No. 2017-13, Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606) , Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments , which further elaborate on the original ASU No. 2014-09. The Company adopted the guidance in ASC 606 on January 1, 2018. Revenue is recognized when control of the promised products or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to for those products and services. In general, the Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, with the customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue when, or as, the Company satisfies a performance obligation The Company provides cloud-based subscription services, which include web hosting and related add-ons, search engine optimization ("SEO") services, domain registration services and email marketing. Web hosting gives customers access to an environment where the Company hosts a customer’s website. The related contract terms are generally for one year , but can range from 30 days to three years . Web hosting services are typically sold in bundled offerings that include web hosting, domain registration services and various add-ons. The Company recognizes revenue for web hosting and domain registration services over the term of the contract. The main add-on services related to web hosting are domain privacy, website security, secure sockets layer security, site backup and restoration, and web builder tools. These services may be included in web hosting bundles, or they may be purchased on a standalone basis. Certain add-on services are provided by third parties. In cases where the Company is acting as an agent for the sale of third-party add-on services, the Company recognizes revenue on a net basis at the time of sale. In cases where the Company is acting as a principal for the sale of third-party add-on services (i.e., the Company has the primary responsibility to provide specific goods or services, it has discretion to establish prices and it may assume inventory risk), the Company recognizes revenue on a gross basis over the term of the contract. The revenue for Company-provided add-on services is primarily recognized over the term of the contract. SEO services are monthly subscriptions that provide a customer with increased traffic to their website over the term of the subscription. Revenue from SEO services is recognized over the monthly term of the contract. In the case of domain registration services, the Company is an accredited registrar and can provide registration services to the customer, or it can select an accredited third-party registrar to perform these duties. Domain registration services are generally annual subscriptions, but can cover multiple years. Revenue for these services is recognized over the life of the subscription. Email marketing services provide customers with a cloud-based platform that can send broadcast emails to a contact list managed by the customer. Pricing is based on contact list volume from the prior monthly period, which determines the contractual billing price for the upcoming month. Revenue for this service is recognized over the monthly term of the contract. Inventory management and marketplace listing services provide customers with a cloud-based platform that integrates standard inventory management features with order management and shipping management capabilities across multiple channels. Pricing is primarily based on order volume from the prior monthly period. For inventory management customers who subscribe to an annual plan, revenue is recognized ratably over the term of the contract. Inventory management professional services are also provided to customers on demand, and are recognized into revenue upon completion. Non-subscription-based services include certain professional services, primarily website design or re-design services, marketing development fund ("MDF") revenue, premium domain names and domain parking services. Website design and re-design services are recognized when the service is complete. Marketing development funds consist of commissions earned by the Company when a third party sells its products or services directly to the Company’s customers, and advertising revenue for third-party ads placed on Company websites. The Company records revenue when the service is provided and calculates it based on the contractual revenue share arrangement or over the term of the advertisement. Domain parking allows the Company to monetize certain of its premium domain names by loaning them to specialized third parties that generate advertising revenue from these parked domains on a pay-per-click basis. Revenue is recognized when earned and calculated based on the revenue share arrangement with the third party. Revenue from the sale of premium domains is recognized when persuasive evidence of an arrangement to sell such domains exists and delivery of an authorization key to access the domain name has occurred. Premium domain names are paid for in advance prior to the delivery of the domain name. The contracts that the Company enters into typically do not contain any variable or non-cash considerations. The Company maintains a reserve for refunds and chargebacks related to revenue that has been recognized and is expected to be refunded, as calculated based on observed historical trends. The Company had a refund and chargeback reserve of $0.4 million and $0.3 million as of December 31, 2018 and September 30, 2019 , respectively. The portion of deferred revenue that was expected to be refunded at December 31, 2018 and September 30, 2019 was $2.2 million and $1.7 million , respectively. Based on refund history, approximately 83% of all refunds happen in the same fiscal month that the contract starts or renews, and approximately 95% of all refunds happen within 45 days of the contract start or renewal date. The Company did not apply any practical expedients during its adoption of ASC 606. The Company elected to use the portfolio method in the calculation of the deferred contract assets. Contracts with Multiple Performance Obligations A considerable amount of the Company’s revenue is generated from transactions that are contracts with customers that may include web hosting plans, domain name registrations, and other cloud-based products and services. In these cases, the Company determines whether the products and services are distinct performance obligations that should be accounted for separately versus together. The Company allocates revenue to each performance obligation based on its relative standalone selling price ("SSP"), generally based on the price charged to customers. Web hosting services, domain name registrations, and other cloud-based products and services have distinct performance obligations and are often sold separately. If the promise is not distinct and therefore not a performance obligation, then the total transaction amount is allocated to the identified performance obligation based on a relative selling price hierarchy. When multiple performance obligations are included in a contract, the total transaction amount for the contract is allocated to the performance obligations based on a relative selling price hierarchy. The Company determines the relative selling price for a performance obligation based on SSP. The Company determines SSP by considering its observed SSPs, competitive prices in the marketplace and management judgment; these SSPs may vary depending upon the particular facts and circumstances related to each deliverable. The Company analyzes the SSPs used in its allocation of transaction amount, at a minimum, on a quarterly basis. Deferred Revenue The Company records deferred revenue when cash payments are received or are due in advance of the Company’s performance, including amounts that are refundable. The following table provides a reconciliation of the Company's deferred revenue as of September 30, 2019 : Short-term Long-term (in thousands) Balance at December 31, 2018 $ 371,758 $ 96,140 Recognition of beginning deferred revenue into revenue, as a result of performance obligations satisfied (323,934 ) — Cash received in advance during the period 652,151 191,750 Recognition of cash received in the period into revenue, as a result of performance obligations satisfied (512,146 ) — Impact of foreign exchange rates (733 ) — Reclassification between short-term and long-term 188,633 (188,633 ) Balance at September 30, 2019 $ 375,729 $ 99,257 The difference between the opening and closing balances of the Company’s deferred revenue liabilities primarily results from the timing difference between the Company’s performance and the customer’s payment. During the nine months ended September 30, 2019 , the Company recognized $323.9 million and $0.0 million , respectively, from beginning deferred revenue current and long-term balances existing at December 31, 2018 . The Company did not recognize any revenue from performance obligations satisfied in prior periods. The following table provides the remaining performance obligation amounts as of September 30, 2019 . These amounts are equivalent to the ending deferred revenue balance of $475.0 million , which includes both short and long-term amounts: Web presence Email marketing Domain Total (in thousands) Remaining performance obligation, short-term $ 260,679 $ 55,983 $ 59,067 $ 375,729 Remaining performance obligation, long-term 84,161 4 15,092 99,257 Total $ 344,840 $ 55,987 $ 74,159 $ 474,986 This backlog of revenue related to future performance obligations is prepaid by customers and supported by executed contracts with customers. The Company has established a reserve of $0.3 million for refunds and chargebacks, 95% of which is expected to materialize in the first 45 days after the contract start date or renewal date. The remainder of the deferred revenue is expected to be recognized in future periods. Deferred Customer Acquisition Costs As a result of the implementation of ASC 606, the Company now capitalizes the incremental costs directly related to obtaining and fulfilling a contract (such as sales commissions and certain direct sales and marketing success-based costs), if these costs are expected to be recovered. These costs are amortized over the period the services are transferred to the customer, which is estimated based on customer churn rates for various segments of the business. The Company includes only those incremental costs that would not have been incurred if the contracts had not been entered into: Short-term Long-term (in thousands) Balance at December 31, 2018 $ 41,458 $ 42,472 Deferred customer acquisition costs incurred in the period 17,969 28,231 Amounts recognized as expense in the period (41,784 ) — Impact of foreign exchange rates (122 ) 80 Reclassification between short-term and long-term 23,007 (23,007 ) Balance at September 30, 2019 $ 40,528 $ 47,776 As of September 30, 2019 , the Company had a total of approximately $73.9 million , $12.6 million and $1.7 million in deferred assets relating to costs incurred to obtain or fulfill contracts in its web presence, email marketing and domain segments, respectively. These deferred assets consist entirely of recoverable, specific, success-based sales commissions. During the nine months ended September 30, 2019 , the Company recognized total amortization costs related to the above items of approximately $34.9 million , $4.7 million , and $2.1 million in its web presence, email marketing and domain segments, respectively, which were included in sales and marketing in the consolidated statements of operations and comprehensive income (loss). Significant Judgments The Company sells a number of third-party cloud-based services to enhance a customer’s overall web hosting experience. The Company exercises considerable judgment to determine if it is the principal or agent in each of these arrangements, and in some instances, has concluded that it is an agent of the third party and recognizes revenue at the time of the customer purchase in an amount that is net of the revenue share payable to the third party. The Company exercises judgment to determine the SSP for each distinct performance obligation. In instances where the SSP is not directly observable, such as when the Company does not sell the product or service separately, the Company determines the SSP using information that may include a competitive market assessment approach and other observable inputs. The Company typically has more than one SSP for individual products and services. Judgment is required to determine whether particular types of sales and marketing costs incurred, including commissions, are incremental and recoverable costs incurred to obtain and fulfill the customer contract. In addition, judgment is required to determine the life of the customer over which deferred customer acquisition costs are amortized.
Income Taxes	Income Taxes Income taxes are accounted for in accordance with FASB ASC 740, Accounting for Income Taxes . Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using the enacted tax rates and laws that will be in effect when the Company expects the differences to reverse. The Company reduces the deferred tax assets by a valuation allowance if, based upon the weight of available evidence, it is more likely than not that the Company will not realize some portion or all of the deferred tax assets. The Company considers relevant evidence, both positive and negative, to determine the need for a valuation allowance. As part of the Tax Cut and Jobs Act of 2017 (the “TCJA”), the Company is subject to a territorial tax system in which it is required to make an accounting policy in providing for tax on Global Intangible Low Taxed Income (“GILTI”) earned by certain foreign subsidiaries. The Company has elected to treat the impact of GILTI as a period cost, to be reported as a part of continuing operations, as a component of income tax expense. The Company establishes reserves when it believes that certain positions are likely to be challenged despite the Company’s assertion that its tax return positions are fully supportable. The calculation of the Company’s tax liabilities involves significant judgment based on individual facts, circumstances, and information available in addition to applying complex tax regulations in various jurisdictions. Under U.S. GAAP, in order to recognize an uncertain tax benefit, the taxpayer must determine it is more likely than not the position will be sustained, and the measurement of the benefit is calculated as the largest amount that is more than 50 percent likely to be realized upon resolution of the benefit. Although the Company believes that it has adequately provided for liabilities resulting from tax assessment by taxing authorities, positions taken by these tax authorities could have an impact on the Company’s results of operations, financial position and/or cash flows. The Company recognizes the interest and penalties related to income taxes as a part of interest expense and operating expenses, respectively, in continuing operations in its consolidated statements of operations and comprehensive income (loss). ASC 740 clarifies the accounting for income taxes by prescribing a minimum recognition threshold that a tax position is required to meet before being recognized in the financial statements. The Company recognizes the effect of income tax positions only if those positions are more likely than not to be sustained. Recognized income tax positions are measured at the largest amount that is more likely than not to be realized. Changes in recognition or measurement are reflected in the period in which the change in judgment occurs.
Stock-Based Compensation	Stock-Based Compensation The Company may issue restricted stock units, restricted stock awards and stock options which vest upon the satisfaction of a performance condition and/or a service condition. The Company follows the provisions of FASB ASC 718, Compensation—Stock Compensation , which requires employee stock-based payments to be accounted for under the fair value method. Under this method, the Company is required to record compensation cost based on the estimated fair value for stock-based awards granted over the requisite service periods for the individual awards, which generally equals the vesting periods, net of estimated forfeitures. The Company uses the straight-line amortization method for recognizing stock-based compensation expense. In addition, for stock-based awards where vesting is dependent upon achieving certain performance goals, the Company estimates the likelihood of achieving the performance goals against established performance targets. The Company estimates the fair value of employee stock options on the date of grant using the Black-Scholes option-pricing model, which requires the use of highly subjective estimates and assumptions. For restricted stock awards and restricted stock units granted, the Company estimates the fair value of each restricted stock award or restricted stock unit based on the closing trading price of its common stock on the date of grant.
Net (Loss) Income per Share	Net (Loss) Income per Share The Company considered FASB ASC 260-10, Earnings per Share , which requires the presentation of both basic and diluted earnings per share in the consolidated statements of operations and comprehensive income (loss). The Company’s basic net (loss) income per share is computed by dividing net (loss) income by the weighted-average number of shares of common stock outstanding for the period, and, if there are dilutive securities, diluted income per share is computed by including common stock equivalents which includes shares issuable upon the exercise of stock options, net of shares assumed to have been purchased with the proceeds, using the treasury stock method.
Recent Accounting Pronouncements	Recent Accounting Pronouncements - Recently Adopted In February 2016, the FASB issued ASU No. 2016-02, Leases, or ASC 842. Since then, the FASB has also issued ASU No. 2018-10, Codification Improvements to Topic 842, Leases , which further clarifies ASU No. 2016-02 and corrects unintended application of guidance. The new standard establishes a right-of-use ("ROU") model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. The new standard is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. A modified retrospective transition approach is required for capital and operating leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company adopted the new standard on January 1, 2019. The Company elected to utilize the available practical expedients and implemented internal controls and reporting systems to enable the preparation of the financial information on adoption and on an ongoing basis subsequent to adoption. Upon adoption, the Company recorded an ROU asset of $114.9 million , and a lease liability of $124.5 million , and reduced accrued facility exit costs by $1.7 million and deferred rent liabilities by $7.9 million . There was no impact to opening retained earnings as a result of the adoption of the new guidance. The impact of applying ASC 842 on the results for reporting periods and balance sheet beginning after January 1, 2019 is presented under ASC 842, while prior amounts are not adjusted and continue to be reported in accordance with the Company’s historic accounting under ASC 840, Leases . The Company's accounting for finance leases remained substantially unchanged. See Note 5, Leases , for further details. Recent Accounting Pronouncements - Recently Issued In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The new guidance provides for the deferral of implementation costs for cloud computing arrangements and expensing those costs over the term of the cloud services arrangement. The Company is currently evaluating the timing of adoption and the expected impact of the new guidance.
