Organization, Consolidation and Presentation of Financial Statements Disclosure	The Company and Summary of Significant Accounting Policies Description of Company Web.com Group, Inc. ("Web.com" or "the Company") provides a full range of Internet services to small businesses to help them compete and succeed online. Web.com meets the needs of small businesses anywhere along their lifecycle with affordable, subscription-based solutions including domains and related security products, hosting, website design and management, search engine optimization, online marketing campaigns, local sales leads, social media, mobile products and eCommerce solutions. For more information about the Company, please visit http://www.web.com. The information obtained on or accessible through the Company's website is not incorporated into this Quarterly Report on Form 10-Q and you may not consider it a part of this Quarterly Report on Form 10-Q. The Company has reviewed the criteria of Accounting Standards Codification ("ASC") 280-10, Segment Reporting, and has determined that the Company is comprised of only one segment, web services and products. On January 31, 2017, the Company acquired 100% of the equity interests of Dattatec.com SRL ("DonWeb.com or DonWeb"), a hosting and domain registration company catering to the Spanish-speaking market, located in Rosario, Argentina. See Note 2, Business Combinations , for additional information surrounding the acquisition. On March 9, 2016, the Company completed the acquisition of 100% of the outstanding shares of Yodle, Inc., a Delaware corporation, ("Yodle"), for approximately $341.3 million , which included $40.9 million of deferred consideration. Yodle is a leading provider of cloud based local marketing solutions for small businesses with approximately 1,400 employees and 53,000 subscribers as of the closing of the acquisition. See Note 2, Business Combinations , for additional information surrounding the acquisition. Basis of Presentation The accompanying consolidated balance sheet as of September 30, 2017 , the consolidated statements of comprehensive income for the three and nine months ended September 30, 2017 and 2016 , the consolidated statements of cash flows for the nine months ended September 30, 2017 and 2016 , and the related notes to the consolidated financial statements are unaudited. The unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements for the year ended December 31, 2016 , except that certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or excluded as permitted. In the opinion of management, the unaudited consolidated financial statements include all adjustments of a normal recurring nature necessary for the fair presentation of the Company’s financial position as of September 30, 2017 , the Company’s results of operations for the three and nine months ended September 30, 2017 and 2016 , and the cash flows for the nine months ended September 30, 2017 and 2016 . The results of operations for the three and nine months ended September 30, 2017 , are not necessarily indicative of the results to be expected for the year ending December 31, 2017 . The Company's financial position as of September 30, 2017 includes the assets and liabilities of Donweb.com and the results of operations and cash flows include Donweb.com from the acquisition date through September 30, 2017 . The results of operations and cash flows include Yodle from the acquisition date through the respective period end dates. Pursuant to the rules and regulations of the SEC, certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been omitted from these interim financial statements. The Company suggests that these financial statements be read in conjunction with the audited financial statements and the notes included in the Company's most recent annual report on Form 10-K filed with the SEC on February 28, 2017, and any subsequently filed current reports on Form 8-K. Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. Sources of Revenue Subscription Revenue The Company currently derives a substantial majority of its revenue from fees associated with our subscription services, which generally include web services, online marketing, eCommerce, and domain name registration offerings. We bill a majority of our customers in advance and recognize revenue on a daily basis over the life of the contract. Generally, revenue is recognized net of sales tax. Professional Services and Other Revenue The Company also generates professional services revenue from custom website design, eCommerce store design and support services. Custom website design and eCommerce store design work is typically billed on a fixed-price basis and over very short periods. Generally, revenue is recognized net of sales tax when the service has been completed. Cost of Revenue and Operating Expenses Cost of Revenue Cost of revenue consists of expenses related to compensation of our web page development staff, domain name registration costs, directory listing fees, eCommerce store design, online marketing costs for services provided, billing costs, hosting expenses, and allocated occupancy overhead costs. The Company allocates occupancy overhead costs such as rent and utilities to all departments based on headcount. Accordingly, general overhead expenses are reflected in each cost of revenue and operating expense category. Sales and Marketing Expense The Company's direct marketing expenses include the costs associated with the online marketing channels used to promote our services and acquire customers. These channels include search marketing, affiliate marketing and partnerships. Sales and marketing costs consist primarily of compensation and related expenses for our sales and marketing staff as well as our customer support staff and allocated occupancy overhead costs. Sales and marketing expenses also include marketing programs, such as advertising, corporate sponsorships and other corporate events and communications. Technology and development Technology and development represents costs associated with creation, development and distribution of our products and websites. Technology and development expenses primarily consist of headcount-related costs associated with the design, development, deployment, testing, operation, enhancement of our products and costs associated with the data centers and all systems infrastructure costs supporting those products as well as all administrative platforms and allocated occupancy overhead costs. General and Administrative Expense General and administrative expenses consist of compensation and related expenses for executive, finance, and administration, as well as professional fees, corporate development costs, other corporate expenses, and allocated occupancy overhead costs. Depreciation and Amortization Expense Depreciation and amortization expenses relate primarily to the Company's intangible assets recorded due to the acquisitions it has completed, as well as depreciation expense from computer and other equipment, internally developed software, furniture and fixtures, and building and improvement expenditures. Foreign Currency Translation The functional currency of the Company’s Argentinian DonWeb operations and its United Kingdom-based operations is the Argentina Peso and British Pound, respectively. The Company translates the financial statements of these subsidiaries to U.S. dollars using month-end rates of exchange for assets and liabilities, historical rates of exchange for equity and average rates of exchange for revenues, costs, and expenses. Translation gains and losses are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. In addition, the Company’s foreign operations include a customer service center and an outbound sales center in Canada and a technology center in Buenos Aires, Argentina. The Company records foreign currency transaction gains and losses, and remeasurement of local currencies of these foreign subsidiaries where the functional currency is different from the local foreign currency in the consolidated statements of comprehensive income. New Accounting Standards Recently Adopted Accounting Standards In March 2016, the FASB issued Accounting Standards Update ("ASU") 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting and is effective for fiscal years beginning after December 15, 2016. The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows, statutory withholding requirements and forfeitures. The Company adopted ASU 2016-09 in the first quarter of 2017 and recorded excess tax benefits (ETBs) as income tax expense or benefit in the income statement prospectively as of the beginning of the year of adoption and the Company continued to record shortfalls as a component of income tax expense consistent with historical practices. For interim reporting purposes, the Company reports ETBs and shortfalls as discrete items in the period in which they occur. For the three and nine months ended September 30, 2017 , the Company recognized a tax benefit related to the adoption of $0.2 million and $1.1 million , respectively. In addition, the guidance eliminates the requirement that ETBs be realized before companies can recognize them. The Company applied this part of the guidance using a modified retrospective transition method and recorded a cumulative-effect adjustment for previously unrecognized ETBs in opening retained earnings on January 1, 2017 upon adoption. The cumulative-effect adjustment for federal and state tax purposes is $27.0 million and $2.7 million , respectively. A valuation allowance was recorded on $1.7 million of these deferred tax assets for a portion of the state adjustment to reflect the amount realized on a "more likely than not" basis. Further, the Company presents ETBs and excess tax deficiencies as an operating activity on the statement of cash flows starting on January 1, 2017. The Company has prospectively adopted this change. The Company continues to record its stock compensation expense based on an estimate of the awards that are expected to vest, rather than recording forfeitures when they occur. Accounting Standards Issued Not Yet Adopted In May 2014, the FASB and International Accounting Standards Board ("IASB") issued ASU 2014-09 Revenue from Contracts with Customers (Topic 606), a converged standard on revenue recognition which supersedes previous revenue recognition guidance. Some of the main areas of transition to the new standard include, among others, transfer of control (revenue is recognized when a customer obtains control of a good or service), allocation of transaction price is based on relative standalone selling price (entities that sell multiple goods or services in a single arrangement must allocate the consideration to each of those goods or services), contract costs (entities sometimes incur costs, such as sales commissions or mobilization activities, to obtain or fulfill a contract), and disclosures (extensive disclosures are required to provide greater insight into both revenue that has been recognized, and revenue that is expected to be recognized in the future from existing contracts). In August 2015, the FASB issued ASU 2015-14 Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date, which defers the effective date of the new standard by one year, resulting in the new standard being effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 with early adoption as of the original effective date permitted. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) and in April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing. Further in May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients. These standards clarify the guidance in ASU 2014-09 and have the same effective date as the original standard. The Company will apply the standard using a modified retrospective approach with the cumulative effect of initially applying the standard recognized at the date of initial application inclusive of certain additional disclosures, as permitted under Topic 606. The Company has substantially completed its initial evaluation of its customer contracts and related costs to acquire and fulfill contracts and is in the process of designing necessary systematic changes to ascertain the initial and ongoing impact of the new standard on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10), which addresses certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. The amendment will be effective for the Company beginning January 1, 2018 and the adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize on the balance sheet a right-of-use asset, representing their right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. ASU 2016-02 is effective for the Company beginning January 1, 2019 and the Company is currently evaluating the impact that ASU 2016-02 will have on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, addressing eight specific cash flow issues in an effort to reduce diversity in practice. The amended guidance is effective for the Company beginning after January 1, 2018, and for interim periods within those years. Early adoption is permitted. The Company is currently evaluating the impact that ASU 2016-15 will have on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, which requires that entities recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The standard will be effective for the Company on January 1, 2018. The adoption is not expected to have a material impact on the consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flow (Topic 230): Restricted Cash, which states that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance will be effective for the Company beginning January 1, 2018, and interim periods within those fiscal years. Early adoption is permitted. Upon adoption, the Company will present restricted cash, which is currently included in other assets, with the cash and cash equivalents balances in the cash flow statement. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The new guidance clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new guidance is effective for the Company beginning after January 1, 2018, including interim periods within those periods. The adoption of this standard is not expected to have a material impact on our consolidated financial statements or disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new guidance requires only a one-step quantitative impairment test, whereby a goodwill impairment loss will be measured as the excess of a reporting unit’s carrying amount over its fair value (not to exceed the total goodwill allocated to that reporting unit). It eliminates Step 2 of the current two-step goodwill impairment test, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. For public companies, the amended guidance is effective for the Company beginning after January 1, 2020. The adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting. The new guidance amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. This standard is effective for the Company beginning January 1, 2018, including interim periods within those periods. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities From Equity (Topic 480) And Derivatves And Hedging (Topic 815): Accounting For Certain Financial Instruments With Down Round Features, Replacement of the Indefinite Deferral For Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests With a Scope Exception. The new guidance changes the classification of certain equity-linked financial instruments (or embedded features) with down round features. The amendments also clarify existing disclosure requirements for equity-classified instruments. For freestanding equity-classified financial instruments, the amendments require entities that present earnings per share (EPS) in accordance with Topic 260, Earnings Per Share, to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features would be subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt—Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). The amendments in Part II of this Update recharacterize the indefinite deferral of certain provisions of Topic 480, Distinguishing Liabilities from Equity, that now are presented as pending content in the Codification, to a scope exception. Those amendments do not have an accounting effect. Part I of the new guidance affects any entity that issues financial instruments that include down round features. The amendments in Part I of this Update that relate to the recognition, measurement, and earnings per share of certain freestanding equity-classified financial instruments that include down round features affect entities that present earnings per share in accordance with the guidance in Topic 260, Earnings Per Share. Part I is effective for the Company beginning January 1, 2019 and Part II did not require transition guidance as the amendment did not have an accounting effect. The adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures.

Business Combinations [Abstract]
Business Combinations	Business Combinations Acquisition of DonWeb.com On January 31, 2017, the Company acquired DonWeb.com, a hosting and domain registration company catering to the Spanish-speaking market, located in Rosario, Argentina. The Company paid approximately $8.6 million at closing. The Company may pay the seller additional consideration of up to $2.0 million on January 31, 2021, present valued to $1.7 million as of the acquisition date, for total consideration of $10.3 million . In addition, the agreement includes a four -year earnout provision that entitles the seller up to $3.0 million of consideration contingent upon the post-acquisition business performance and employment. Earnout amounts are recorded as compensation expense. Transaction costs associated with the acquisition were not significant and the results of operations from DonWeb during the three and nine months ended September 30, 2017 were not material for disclosure herein. The Company has accounted for the acquisition using the acquisition method as required by ASC 805, Business Combinations. As such, preliminary fair values have been assigned to the assets acquired and liabilities assumed and the excess of the total purchase price over the fair value of the net assets acquired is recorded as goodwill. The Company, with the assistance of independent valuation professionals, has also performed preliminary estimates of the fair value of certain intangible assets. The goodwill recorded from this acquisition represents business benefits the Company anticipates realizing from acquiring an entity in the Spanish-speaking market, and is not expected to be deductible for income tax purposes. In connection with the acquisition, the Company recorded approximately $4.0 million of liabilities arising from pre-acquisition matters that are more likely than not to be sustained upon examination, inclusive of interest and penalties for which the Company is indemnified. The following table summarizes the Company's preliminary purchase price allocation based on the fair values of the assets acquired and the liabilities assumed. As of September 30, 2017 Tangible current assets $ 1,370 Property plant and equipment 2,331 Domain/Trade names 1,074 Non-competes 218 Customer relationships 1,655 Other non current assets 2,849 Goodwill 10,957 Current liabilities (1,617 ) Deferred revenue (2,860 ) Other long term liabilities (5,629 ) Purchase price consideration $ 10,348 The Company is still reviewing information surrounding intangible assets, certain assets and liabilities, income taxes and deferred revenue. These items may result in changes to the Company's preliminary purchase price allocation. The preliminary non-competes and customer relationships will be amortized over 4 years and 3 years respectively. The domain and trade names are indefinite life intangible assets and are not amortized. Acquisition of Yodle On March 9, 2016, the Company executed an Agreement and Plan of Merger (the "Merger Agreement) with Yodle, Inc., a Delaware corporation ("Yodle"), and Shareholder Representative Services, LLC, a Colorado limited liability company. The Company acquired 100% of the outstanding shares of Yodle, Inc. and paid approximately $300.3 million adjusted for, among other things, Yodle's cash and outstanding debt and transaction related expenses. The Company paid an additional $18.9 million on March 9, 2017 and will pay $22.0 million on the second anniversary date of the closing, subject to adjustments as described in the Merger Agreement. Finally, the Company converted out of the money stock options held by employees of Yodle to Web.com options, which resulted in additional consideration of $2.3 million , for total consideration of $341.3 million . In addition to the consideration, the Company incurred approximately $3.9 million of acquisition-related transaction expenses which are reflected as a general and administrative expense in the consolidated statements of comprehensive income. The Company has accounted for the acquisition of Yodle using the acquisition method as required by ASC 805. Pro Forma Condensed Consolidated Results of Operations The Company has prepared the unaudited condensed pro forma financial information to reflect the consolidated results of operations as though the Yodle acquisition had occurred on January 1, 2016 for the nine months ended September 30, 2016 . The Company has made adjustments to the historical Web.com and Yodle financial statements that are directly attributable to the acquisition, factually supportable and expected to have a continuing impact on the combined results. The pro forma presentation does not include any impact of transaction costs or expected synergies. The pro forma results are not necessarily indicative of our results of operations had the Company owned Yodle for the entire periods presented. The Company has adjusted the results of operations to reflect the impact of amortizing into revenue, deferred revenue that was recorded at fair value. In addition, interest expense and amortization of intangible assets were adjusted to reflect the cost of the March 9, 2016 debt issued to finance the acquisition and the fair value of the intangible assets on the acquisition date, respectively. The following summarizes unaudited pro forma total revenue and net loss (in thousands, except per share amounts): Nine months ended September 30, 2016 Revenue $ 563,272 Net loss $ (1,557 ) Basic net loss per share $ (0.03 ) Diluted net loss per share $ (0.03 ) Basic weighted-average common shares outstanding 49,221 Diluted weighted-average common shares outstanding 49,221 Acquisition of TORCHx On May 31, 2016, the Company completed the acquisition of substantially all of the assets and certain liabilities of Brokerage Leader Inc. ("TORCHx"), a Florida corporation, which primarily consisted of customer relationships and developed technology intangible assets. TORCHx is a real estate platform built for agents and brokerages that features search engine optimization (SEO) and responsive design, customer relationship management (CRM) and other tools to help run successful online marketing campaigns. The Company paid $4.4 million for this business during the second quarter of 2016, of which $3.0 million was paid at closing and the remaining $1.4 million is payable on November 30, 2017. The Company has accounted for the acquisition of TORCHx using the acquisition method as required in ASC 805. As such, fair values have been assigned to the assets acquired and liabilities assumed and the excess of the total purchase price over the fair value of the net assets acquired is recorded as goodwill. The Company estimated the fair value of certain intangible assets. The goodwill recorded from this acquisition represents business benefits the Company anticipates realizing from optimizing resources and cross-sale opportunities. The goodwill from the acquisition is deductible for tax purposes.

Net Income Per Common Share

Earnings Per Share [Abstract]
Net Income Per Common Share	Net Income Per Common Share Basic net income per common share is calculated using net income and the weighted-average number of shares outstanding during the reporting period. Diluted net income per common share includes the effect from the potential issuance of common stock, such as common stock issued pursuant to the exercise of stock options or vesting of restricted shares. The Company issues equity awards with performance, service and market conditions. These awards are included in basic shares outstanding once all criteria have been met and the shares have vested. Prior to the end of the vesting period, the number of contingently issuable shares included in diluted EPS is based on the number of shares, if any, that would be issuable under the terms of the arrangement if the end of the reporting period were the end of the contingency period, using the treasury stock method and assuming the result would be dilutive. See Note 10, Stock-Based Compensation and Stockholders' Equity , for additional information on this award. During the three months ended September 30, 2017 and 2016 , 1.8 million and 3.6 million share-based awards, respectively, have been excluded from the calculation of diluted common shares because including those securities would have been anti-dilutive. During the nine months ended September 30, 2017 and 2016 , 2.8 million and 3.7 million share-based awards, respectively, have been excluded from the calculation of diluted common shares because including those securities would have been anti-dilutive. The Company's potentially dilutive shares also include incremental shares issuable upon the conversion of the Company's Senior Convertible Notes due August 15, 2018 ("2018 Notes"). See Note 6, Long-term Debt , for additional information regarding the 2018 Notes. Upon conversion or maturity of the 2018 Notes, the Company may settle the notes with either cash, shares of its common stock or a combination of cash and shares of its common stock, at its election. The Company has adopted a current policy to settle the principal amount in cash and any excess conversion value in shares of our common stock. Because the principal amount of the 2018 Notes will be settled in cash upon conversion, only the conversion spread relating to the 2018 Notes is included in our calculation of diluted net income per common share. When the market price of the Company's stock exceeds the conversion price, as applicable, it will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued upon conversion using the treasury stock method. There were no incremental common shares from the 2018 Notes that were included in the calculation of diluted shares because the Company's average price of its common stock did not exceed the conversion price during the three and nine months ended September 30, 2017 and 2016 . The following table sets forth the computation of basic and diluted net income per common share (in thousands, except per share amounts): Three months ended September 30, Nine months ended September 30, 2017 2016 2017 2016 Net income $ 8,301 $ 3,346 $ 22,863 $ 2,077 Basic weighted average common shares outstanding 48,888 49,221 49,150 49,296 Dilutive effect of stock options 1,541 1,281 1,389 1,347 Dilutive effect of restricted shares 584 269 551 327 Dilutive effect of performance shares — — 3 — Diluted weighted average common shares outstanding 51,013 50,771 51,093 50,970 Net income per basic common share $ 0.17 $ 0.07 0.47 0.04 Net income per diluted common share $ 0.16 $ 0.07 $ 0.45 $ 0.04

Debt Disclosure [Abstract]
Long-term Debt	Long-Term Debt 1% Senior Convertible Notes due August 15, 2018 In August 2013, the Company issued $258.8 million aggregate principal amount of 1.00% Senior Convertible Notes due August 15, 2018 (the "2018 Notes"). The 2018 Notes bear interest at a rate of 1.00% per year, payable semiannually in arrears, on February 15 and August 15 of each year, beginning on February 15, 2014. The conversion price for the 2018 Notes is equivalent to an initial effective conversion price of approximately $35.00 per share of common stock. Proceeds, net of original issuance discounts and debt issuance costs, of $252.3 million were received from the 2018 Notes. The net proceeds were used to pay down $208.0 million of the First Lien Term Loan and $43.0 million of the Revolving Credit Facility. On or after August 20, 2016 , the Company may redeem for cash any or all of the 2018 Notes, at its option, if the last reported sale price of its common stock exceeds 130% of the applicable conversion price on each applicable trading day as defined by the indenture. The redemption price will equal 100% of the principal amount of the 2018 Notes to be redeemed, plus accrued and unpaid interest to, but not including, the redemption date. Holders of the 2018 Notes may also convert their notes at any time prior to May 15, 2018 if the sale price of the Company's common stock exceeds 130% of the applicable conversion price on each applicable trading day as defined by the indenture. In addition, holders may also convert their 2018 Notes any time prior to May 15, 2018 , (i) if during the five business days after any five consecutive trading day period in which the trading price of the 2018 Notes was less than 98% of the product of the last reported sale price of the Company's common stock and the conversion rate, (ii) if the Company calls the 2018 Notes for redemption; or (iii) upon the occurrence of specified corporate events. The 2018 Notes are senior unsecured obligations and will be effectively junior to any of the Company's existing and future secured indebtedness. The Company determined that the embedded conversion option in the 2018 Notes is not required to be separately accounted for as a derivative under ASC 815, Derivatives and Hedging . The 2018 Notes are within the scope of ASC 470, Topic 20, Debt with Conversion and Other Options, which requires the Company to separate a liability component and an equity component from the proceeds received. The carrying amount of the liability component at the time of the transaction of $204.4 million was calculated by measuring the fair value of a similar debt instrument that does not have an associated equity component. The fair value of the liability component was subtracted from the initial proceeds and the remaining amount of $47.8 million was recorded as the equity component. The excess of the principal amount of the liability component over its carrying amount will be amortized to interest expense over the expected life of 5 years using the effective interest method. Upon conversion or maturity of the 2018 Notes, the Company may settle the notes with either cash, shares of its common stock or a combination of cash and shares of its common stock, at its election. The Company has adopted a current policy to settle the $258.8 million of principal amount in cash and any excess conversion value in shares of its common stock. Because the principal amount of the 2018 Notes will be settled in cash upon conversion, only the conversion spread relating to the 2018 Notes may be included in the Company's calculation of diluted net income per common share. When the market price of the Company's stock exceeds the conversion price, it will include, in the diluted net income per common share calculation, the effect of the additional shares that may be issued upon conversion using the treasury stock method. As such, the 2018 Notes have no impact on diluted net income per common share until the price of the Company's common stock exceeds the conversion price (approximately $35.00 per common share) of the 2018 Notes. As of September 30, 2017 and December 31, 2016 , the carrying value of the debt and equity component was $248.0 million and $47.8 million and $239.2 million and $47.8 million , respectively. The unamortized debt discount of $10.8 million as of September 30, 2017 will be amortized over the remaining life of ten months using the effective interest method. The Company has included $216.7 million of the 2018 Notes as long-term debt based upon our intent and ability to refinance these obligations. Credit Agreement On February 11, 2016, the Company entered into an amendment (the "Amendment") to that certain Credit Agreement, dated as of September 9, 2014 (the "Existing Credit Agreement" and as amended by the Amendment, the "Amended Credit Agreement"), by and among the Company, the several lenders from time to time parties thereto, and JPMorgan Chase Bank, N.A., as administrative agent. On March 9, 2016 (the "Closing Date"), the amended Credit Agreement became effective following the completion of the acquisition of Yodle Inc. (the "Acquisition"). On May 18, 2017, the Company entered into a second amendment to the Credit Agreement ("Second Amendment"). The Amended Credit Agreement provided (i) $390.0 million of five -year secured term loans, replacing and refinancing $190.0 million of secured term loans outstanding under the Existing Credit Agreement and providing for an additional $200.0 million of secured term loans (the "Term Loan") and (ii) a five -year secured revolving credit facility that provides up to $150.0 million of revolving loans (the "Revolving Credit Facility"), which replaces the revolving credit facility under the Existing Credit Agreement. On the Closing Date, the Company used the proceeds of the Term Loan and borrowed $115.0 million of loans under the Revolving Credit Facility, together with cash on hand, to complete the Acquisition. The Second Amendment to the Credit Agreement provided an incremental $ 50.0 million of secured Term Loan and an incremental $ 110.0 million of borrowing capacity on the Revolving Credit Facility with maturity dates that were commensurate with the Amended Credit Agreement. The Company used the proceeds from the incremental Term Loan to repay the then outstanding amount drawn on the Revolving Credit Facility at the date of closing. The Term Loan and loans under the Revolving Credit Facility initially bore interest at a rate equal to either, at the Company’s option, the LIBOR rate plus an applicable margin equal to 3.00% per annum, or the prime lending rate plus an applicable margin equal to 2.00% per annum. The applicable margins for the Term Loan and loans under the Revolving Credit Facility are subject to reduction or increase based upon the Company’s consolidated first lien net leverage ratio as of the end of each fiscal quarter. Effective August 2017, the Company's interest rate on these loans was reduced to the LIBOR rate plus the applicable margin of 2.00% per an num as a result of reaching certain financial covenant ratios. The Company must also pay (i) a commitment fee of 0.40% per annum on the actual daily amount by which the revolving credit commitment exceeds then-outstanding usage under the Revolving Credit Facility, also subject to reduction or increase based upon the Company’s consolidated first lien net leverage ratio, (ii) a letter of credit fee equal to the applicable margin that applies to LIBOR loans under the Revolving Credit Facility and (iii) a fronting fee of 0.125% per annum, calculated on the daily amount available to be drawn under each letter of credit issued under the Revolving Credit Facility. The Company is permitted to make voluntary prepayments with respect to the Revolving Credit Facility and the Term Loan at any time without payment of a premium. The Company is required to make mandatory prepayments of the Term Loan with (i) net cash proceeds from certain asset sales (subject to reinvestment rights) and (ii) net cash proceeds from certain issuances of debt. The Company is also required to maintain certain financial ratios under the Credit Agreement and there are customary covenants that limit the incurrence of debt, the payment of dividends, the disposition of assets, and making of certain payments. Substantially all of the Company's and certain of its domestic subsidiaries' tangible and intangible assets are pledged as collateral under the Credit Agreement. Both of the aforementioned amendments were accounted for as a modification of the credit agreement and as a result, $1.9 million of additional loan origination discounts and bank lender fees were capitalized during the second quarter ended June 30, 2017 and $5.7 million during the first quarter ended March 31, 2016. The Company has $226.1 million of available borrowings under the Revolving Credit Facility as of September 30, 2017 . Outstanding long-term debt and the interest rates in effect at September 30, 2017 and December 31, 2016 consist of the following (in thousands): September 30, December 31, Revolving Credit Facility maturing 2021, 3.23% based on LIBOR plus 2.00% $ 32,000 $ 47,094 Term Loan due 2021, 3.23% based on LIBOR plus 2.00% less unamortized discount of $4,102 at September 30, 2017, effective rate of 3.58% 385,632 377,851 Senior Convertible Notes, maturing 2018, 1.00%, less unamortized discount of $10,796 at September 30, 2017, effective rate of 5.88% 248,011 239,196 Total Outstanding Debt 665,643 664,141 Less: Current Portion of Long-Term Debt (31,266 ) (16,847 ) Long-Term Portion $ 634,377 $ 647,294 Debt discount and issuance costs The Company recorded $3.9 million and $3.6 million of expense from amortizing debt issuance and discount costs during each of the three months ended September 30, 2017 and 2016 , respectively. During the nine months ended September 30, 2017 and 2016 , $10.7 million and $10.3 million of amortization expense was recorded, respectively.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company applies the following fair value hierarchy, which prioritizes the inputs used to measure fair value into three levels as follows: Level 1 -Quoted prices in active markets for identical assets or liabilities. Level 2 -Observable inputs other than quoted prices in active markets for identical assets and liabilities, quoted prices for identical or similar assets or liabilities in inactive markets, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 -Inputs that are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The Company has financial assets and liabilities that are not required to be remeasured to fair value on a recurring basis. The carrying value of the Company’s cash and cash equivalents, accounts receivable, accounts payable, deferred consideration and accrued expenses approximates fair market value as of September 30, 2017 and December 31, 2016 due to the short maturity of these items. As of September 30, 2017 , the fair value and carrying value of the Company’s 2018 Notes totaled $257.0 million and $248.0 million , respectively. As of December 31, 2016 , the fair value and carrying value of the Company's 2018 Notes was $ 248.6 million and $239.2 million , respectively. The fair value of the 2018 Notes, including the equity component, was calculated by taking the quoted market price for the instruments multiplied by the principal amount. This is based on a Level 2 fair value hierarchy calculation obtained from quoted market prices for the Company’s long-term debt instruments that may not be actively traded at each respective period end. The Revolving Credit Facility and Term Loan are variable rate debt instruments indexed to 1-Month LIBOR that resets monthly and the fair value approximates the carrying value as of September 30, 2017 and December 31, 2016 . See Note 6, Long-term Debt , for additional information surrounding the amendment.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company accounts for income taxes under the provisions of ASC 740, Income Taxes , using the liability method. ASC 740 requires recognition of deferred tax liabilities and assets for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax liabilities and assets are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the difference is expected to reverse. The Company recorded income tax expense of $6.7 million and $6.5 million during the three months ended September 30, 2017 and 2016 , and $19.7 million and $8.0 million during the nine months ended September 30, 2017 and 2016 , respectively, based upon the estimated annual effective tax rates for each year. The estimated annual effective tax rate for 2017 and 2016 reflects the impact of net unfavorable permanent book-tax differences, primarily driven by stock compensation costs estimated for the year and an increase in the projected year-end valuation allowance related to certain state and foreign deferred tax assets.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Standby Letters of Credit The Company utilizes letters of credit to back certain payment obligations relating to its facility operating leases. The Company had approximately $ 6.9 million in standby letters of credit as of September 30, 2017 , $ 1.9 million of which were issued under the Revolving Credit Facility. Legal Proceedings On July 13, 2017, the Company was named as a defendant in a lawsuit in the United States District Court for the Middle District of Florida. The plaintiff in the case alleges that the Company infringed upon certain copyrights, misappropriated trade secrets, breached contracts, and violated the Florida Deceptive and Unfair Trade Practices Act. The plaintiff seeks damages in an unspecified amount. The Company believes that it has meritorious defenses against these purported claims, which it will vigorously pursue. On October 20, 2017, the Court entered a preliminary injunction against the Company, which the Company appealed on October 24, 2017. The appeal is still pending. Given the inherent uncertainties of litigation, including the early stage of these cases, the unknown size of any claim, and legal and factual issues in dispute, the outcome of this case cannot be predicted and a range of loss, if any, cannot currently be estimated. From time to time, the Company and its subsidiaries receive inquiries from foreign, federal, state and local regulatory authorities or are named as defendants in various investigations, inquires or legal actions that are incidental to our business and arise out of or are related to claims made in connection with our marketing practices, customer and vendor contracts and employment related disputes. We believe that the resolution of these investigations, inquiries or legal actions will not have a material adverse effect on our financial position, marketing practices or results of operations. Indemnifications The Company has agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by them in any action or proceeding to which any of them is, or is threatened to be, made a party by reason of his service as a director or officer, including any action by the Company, arising out of his services as the Company’s director or officer or his services provided to any other company or enterprise at the Company’s request. Other The Company is responsible for charging end customers certain taxes in numerous jurisdictions. In the ordinary course of its business, there are many transactions and calculations where the ultimate tax determination is uncertain. In the future, the Company may come under audit, which could result in changes to its tax estimates. The Company routinely assesses these matters and although the Company believes its tax estimates are reasonable, the final determination of tax audits could be materially different than the Company’s estimates, which would result in the Company recording an expense in the period in which a final determination is made.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation and Stockholders' Equity	Stock-Based Compensation and Stockholders' Equity The Company records compensation expense for employee and director stock-based compensation plans based upon the fair value of the award in accordance with ASC 718, Compensation-Stock Compensation. Equity Incentive Plans The Company has the 2014 Equity Incentive Plan for the issuance of stock-based compensation, including but not limited to, common stock options and restricted shares to employees. In addition, the Company’s plan provides for grants of non-statutory stock options and restricted shares awards (“RSA’s”) to non-employee directors. The Company issues shares out of treasury stock, if available, upon the exercise of stock options, otherwise new shares of common stock are issued. Restricted shares are issued out of common stock when they are granted. Incentive stock options and non-statutory stock options issued generally vest ratably over three to four years, are contingent upon continued service and expire ten years from the grant date. Restricted share awards generally vest 25 percent each year over a four year period. The Board of Directors or a committee thereof, administers all of the equity incentive plans and establishes the terms of options granted, including the exercise price, the number of shares subject to individual option awards and the vesting period of options, within the limits set forth in the plans. Options have a maximum term of 10 years and vest as determined by the Board of Directors. The Company has additional equity incentive plans that are established in conjunction with its acquisitions. These plans are considered one-time, inducement awards of incentive stock options, non-statutory stock options and restricted shares. Once the inducement awards are granted, no additional shares, including forfeitures and cancellations, are available for future grant under these plans. Yodle Equity Grants In connection with the March 2016 Yodle acquisition, the Company granted 0.3 million restricted shares that vest annually over a four year period and 0.3 million stock options of which 25 percent vest one year from the date of grant and the remaining 75 percent vest monthly over a three year period for a total of four years. In addition, the Company converted unvested and out of the money existing Yodle stock options to 1.3 million stock options of the Company in connection with the March 9, 2016 acquisition of Yodle. The total value of the converted stock options was approximately $8.3 million . Approximately $2.3 million has been recorded as additional consideration representing the vesting that occurred prior to the closing of the acquisition. The remaining $6.0 million is amortized to stock compensation expense over the remaining service period of approximately three years. Performance Shares During the first quarter of 2017 and 2016 , the Compensation Committee of the Board of Directors approved the issuance of performance share equity awards. The targeted number of shares under a 100 percent payout scenario for each of the 2017 and 2016 awards granted are 0.2 million shares and 0.2 million shares, respectively, earned over the three year vesting periods, with one-third vesting each year. The actual number of shares that may be earned and issued, if any, may range from 0-200% of the target number of shares granted. The range is based upon (1) the number of shares earned based upon the over achievement or under achievement of the financial measures for the annual performance period and (2) the number of shares earned being adjusted higher or lower depending on the performance of the Company's total shareholder return, compared against the Company's peer group. Compensation expense related to the performance share stock plan for the three months ended September 30, 2017 and 2016 was approximately and $0.8 million and $0.3 million , respectively. Compensation expense for the nine months ended September 30, 2017 and 2016 was $2.7 million and $0.8 million respectively. The 2016 tranche of the performance share award resulted in a payout of 43% of the target shares, or approximately 41 thousand shares during the first quarter of 2017 . During the nine months ended September 30, 2017 , approximately 17 thousand shares totaling $0.3 million were withheld by the Company for minimum income tax withholding requirements. Stock Options Compensation expense related to the Company’s stock option plans was $1.8 million and $2.5 million for the three months ended September 30, 2017 and 2016 , respectively. Compensation expense for the nine months ended September 30, 2017 and 2016 was $5.8 million and $7.2 million , respectively. During the three months ended September 30, 2017 and 2016 , 0.3 million and 0.5 million common shares were issued for options exercised, respectively. During the nine months ended September 30, 2017 and 2016 , 0.9 million and 0.6 million common shares were issued for options exercised, respectively. During the nine months ended September 30, 2017 and 2016 , 1.0 million and 1.3 million options were granted, respectively. The weighted-average grant-date fair value of an option granted during the nine months ended September 30, 2017 and 2016 was $8.63 and $8.12 , respectively. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant. Below are the ranges of assumptions used in calculating the fair value of options granted during the following periods: Nine months ended September 30, 2017 2016 Risk-free interest rate 1.84% - 1.98% 1.11% - 1.39% Dividend yield N/A N/A Expected life (in years) 5.02 - 5.07 4.97 - 5.19 Volatility 42.77% - 44.67% 52.21% - 53.82% Restricted Stock Compensation expense related to restricted stock plans for the three months ended September 30, 2017 and 2016 , was approximately $3.1 million and $2.2 million , respectively. Compensation expense for the nine months ended September 30, 2017 and 2016 was $8.8 million and $7.3 million , respectively. During the nine months ended September 30, 2017 and 2016 , approximately 0.2 million and 0.2 million shares totaling approximately $3.2 million and $3.5 million , respectively, were withheld by the Company for minimum income tax withholding requirements. During the three months ended September 30, 2017 and 2016 , 15 thousand and 0.2 million restricted common shares were granted, respectively. During the nine months ended September 30, 2017 and 2016 , 0.9 million and 0.8 million restricted common shares were granted, respectively. This excludes the Yodle restricted stock awards discussed above. The weighted-average grant-date fair value of restricted stock granted during the three months ended September 30, 2017 and 2016 was $22.80 and $17.07 , respectively. The weighted-average grant-date fair value of restricted stock granted during the nine months ended September 30, 2017 and 2016 was $20.47 and $17.70 , respectively. Stock Repurchases On November 5, 2014 , the Company's Board of Directors authorized a share repurchase program of up to $100.0 million of the Company's common stock expiring on December 31, 2016 . In October 2016, the Company's Board of Directors authorized that the share repurchase program of the Company's outstanding securities be extended through December 31, 2018 and be increased by an additional $100.0 million . The aggregate amount remaining available for repurchase under this program was $33.6 million at September 30, 2017 . Repurchases under the repurchase programs may take place in the open market or in privately negotiated transactions, including structured and derivative transactions such as accelerated share repurchase transactions, and may be made under a Rule 10b5-1 plan. During the three months ended September 30, 2017 , the Company repurchased 3.0 million shares for a total of $74.4 million . During the three months ended September 30, 2016 , the Company repurchased approximately 32 thousand common shares for a total of $0.6 million . During the nine months ended September 30, 2017 and 2016 , the Company repurchased approximately 3.1 million and 1.0 million common shares, respectively. The total amount repurchased during the nine months ended September 30, 2017 and 2016 was $76.5 million and $17.5 million , respectively.

Basis of Presentation	Basis of Presentation The accompanying consolidated balance sheet as of September 30, 2017 , the consolidated statements of comprehensive income for the three and nine months ended September 30, 2017 and 2016 , the consolidated statements of cash flows for the nine months ended September 30, 2017 and 2016 , and the related notes to the consolidated financial statements are unaudited. The unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements for the year ended December 31, 2016 , except that certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or excluded as permitted. In the opinion of management, the unaudited consolidated financial statements include all adjustments of a normal recurring nature necessary for the fair presentation of the Company’s financial position as of September 30, 2017 , the Company’s results of operations for the three and nine months ended September 30, 2017 and 2016 , and the cash flows for the nine months ended September 30, 2017 and 2016 . The results of operations for the three and nine months ended September 30, 2017 , are not necessarily indicative of the results to be expected for the year ending December 31, 2017 . The Company's financial position as of September 30, 2017 includes the assets and liabilities of Donweb.com and the results of operations and cash flows include Donweb.com from the acquisition date through September 30, 2017 . The results of operations and cash flows include Yodle from the acquisition date through the respective period end dates. Pursuant to the rules and regulations of the SEC, certain information and disclosures normally included in the notes to the annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("GAAP") have been omitted from these interim financial statements. The Company suggests that these financial statements be read in conjunction with the audited financial statements and the notes included in the Company's most recent annual report on Form 10-K filed with the SEC on February 28, 2017, and any subsequently filed current reports on Form 8-K.
Use of Estimates	Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.
Subscription Revenue	Subscription Revenue The Company currently derives a substantial majority of its revenue from fees associated with our subscription services, which generally include web services, online marketing, eCommerce, and domain name registration offerings. We bill a majority of our customers in advance and recognize revenue on a daily basis over the life of the contract. Generally, revenue is recognized net of sales tax.
Professional Services and Other Revenue	Professional Services and Other Revenue The Company also generates professional services revenue from custom website design, eCommerce store design and support services. Custom website design and eCommerce store design work is typically billed on a fixed-price basis and over very short periods. Generally, revenue is recognized net of sales tax when the service has been completed.
Cost of Revenue	Cost of Revenue Cost of revenue consists of expenses related to compensation of our web page development staff, domain name registration costs, directory listing fees, eCommerce store design, online marketing costs for services provided, billing costs, hosting expenses, and allocated occupancy overhead costs. The Company allocates occupancy overhead costs such as rent and utilities to all departments based on headcount. Accordingly, general overhead expenses are reflected in each cost of revenue and operating expense category.
Sales and Marketing Expense	Sales and Marketing Expense The Company's direct marketing expenses include the costs associated with the online marketing channels used to promote our services and acquire customers. These channels include search marketing, affiliate marketing and partnerships. Sales and marketing costs consist primarily of compensation and related expenses for our sales and marketing staff as well as our customer support staff and allocated occupancy overhead costs. Sales and marketing expenses also include marketing programs, such as advertising, corporate sponsorships and other corporate events and communications.
Technology and development	Technology and development Technology and development represents costs associated with creation, development and distribution of our products and websites. Technology and development expenses primarily consist of headcount-related costs associated with the design, development, deployment, testing, operation, enhancement of our products and costs associated with the data centers and all systems infrastructure costs supporting those products as well as all administrative platforms and allocated occupancy overhead costs.
General and Administrative Expense	General and Administrative Expense General and administrative expenses consist of compensation and related expenses for executive, finance, and administration, as well as professional fees, corporate development costs, other corporate expenses, and allocated occupancy overhead costs.
Depreciation and Amortization Expense	Depreciation and Amortization Expense Depreciation and amortization expenses relate primarily to the Company's intangible assets recorded due to the acquisitions it has completed, as well as depreciation expense from computer and other equipment, internally developed software, furniture and fixtures, and building and improvement expenditures.
Foreign Currency Transactions	Foreign Currency Translation The functional currency of the Company’s Argentinian DonWeb operations and its United Kingdom-based operations is the Argentina Peso and British Pound, respectively. The Company translates the financial statements of these subsidiaries to U.S. dollars using month-end rates of exchange for assets and liabilities, historical rates of exchange for equity and average rates of exchange for revenues, costs, and expenses. Translation gains and losses are recorded in accumulated other comprehensive income (loss) as a component of stockholders’ equity. In addition, the Company’s foreign operations include a customer service center and an outbound sales center in Canada and a technology center in Buenos Aires, Argentina. The Company records foreign currency transaction gains and losses, and remeasurement of local currencies of these foreign subsidiaries where the functional currency is different from the local foreign currency in the consolidated statements of comprehensive income.
New Accounting Standards	New Accounting Standards Recently Adopted Accounting Standards In March 2016, the FASB issued Accounting Standards Update ("ASU") 2016-09, Compensation-Stock Compensation: Improvements to Employee Share-Based Payment Accounting and is effective for fiscal years beginning after December 15, 2016. The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows, statutory withholding requirements and forfeitures. The Company adopted ASU 2016-09 in the first quarter of 2017 and recorded excess tax benefits (ETBs) as income tax expense or benefit in the income statement prospectively as of the beginning of the year of adoption and the Company continued to record shortfalls as a component of income tax expense consistent with historical practices. For interim reporting purposes, the Company reports ETBs and shortfalls as discrete items in the period in which they occur. For the three and nine months ended September 30, 2017 , the Company recognized a tax benefit related to the adoption of $0.2 million and $1.1 million , respectively. In addition, the guidance eliminates the requirement that ETBs be realized before companies can recognize them. The Company applied this part of the guidance using a modified retrospective transition method and recorded a cumulative-effect adjustment for previously unrecognized ETBs in opening retained earnings on January 1, 2017 upon adoption. The cumulative-effect adjustment for federal and state tax purposes is $27.0 million and $2.7 million , respectively. A valuation allowance was recorded on $1.7 million of these deferred tax assets for a portion of the state adjustment to reflect the amount realized on a "more likely than not" basis. Further, the Company presents ETBs and excess tax deficiencies as an operating activity on the statement of cash flows starting on January 1, 2017. The Company has prospectively adopted this change. The Company continues to record its stock compensation expense based on an estimate of the awards that are expected to vest, rather than recording forfeitures when they occur. Accounting Standards Issued Not Yet Adopted In May 2014, the FASB and International Accounting Standards Board ("IASB") issued ASU 2014-09 Revenue from Contracts with Customers (Topic 606), a converged standard on revenue recognition which supersedes previous revenue recognition guidance. Some of the main areas of transition to the new standard include, among others, transfer of control (revenue is recognized when a customer obtains control of a good or service), allocation of transaction price is based on relative standalone selling price (entities that sell multiple goods or services in a single arrangement must allocate the consideration to each of those goods or services), contract costs (entities sometimes incur costs, such as sales commissions or mobilization activities, to obtain or fulfill a contract), and disclosures (extensive disclosures are required to provide greater insight into both revenue that has been recognized, and revenue that is expected to be recognized in the future from existing contracts). In August 2015, the FASB issued ASU 2015-14 Revenue from Contracts with Customers (Topic 606), Deferral of the Effective Date, which defers the effective date of the new standard by one year, resulting in the new standard being effective for fiscal years, and interim periods within those years, beginning after December 15, 2017 with early adoption as of the original effective date permitted. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) and in April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers: Identifying Performance Obligations and Licensing. Further in May 2016, the FASB issued ASU 2016-12, Revenue from Contracts with Customers: Narrow-Scope Improvements and Practical Expedients. These standards clarify the guidance in ASU 2014-09 and have the same effective date as the original standard. The Company will apply the standard using a modified retrospective approach with the cumulative effect of initially applying the standard recognized at the date of initial application inclusive of certain additional disclosures, as permitted under Topic 606. The Company has substantially completed its initial evaluation of its customer contracts and related costs to acquire and fulfill contracts and is in the process of designing necessary systematic changes to ascertain the initial and ongoing impact of the new standard on its consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (Subtopic 825-10), which addresses certain aspects of the recognition, measurement, presentation and disclosure of financial instruments. The amendment will be effective for the Company beginning January 1, 2018 and the adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires lessees to recognize on the balance sheet a right-of-use asset, representing their right to use the underlying asset for the lease term, and a lease liability for all leases with terms greater than 12 months. The guidance also requires qualitative and quantitative disclosures designed to assess the amount, timing and uncertainty of cash flows arising from leases. The standard requires the use of a modified retrospective transition approach, which includes a number of optional practical expedients that entities may elect to apply. ASU 2016-02 is effective for the Company beginning January 1, 2019 and the Company is currently evaluating the impact that ASU 2016-02 will have on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, addressing eight specific cash flow issues in an effort to reduce diversity in practice. The amended guidance is effective for the Company beginning after January 1, 2018, and for interim periods within those years. Early adoption is permitted. The Company is currently evaluating the impact that ASU 2016-15 will have on its consolidated financial statements. In October 2016, the FASB issued ASU 2016-16, which requires that entities recognize the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. The standard will be effective for the Company on January 1, 2018. The adoption is not expected to have a material impact on the consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flow (Topic 230): Restricted Cash, which states that amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amended guidance will be effective for the Company beginning January 1, 2018, and interim periods within those fiscal years. Early adoption is permitted. Upon adoption, the Company will present restricted cash, which is currently included in other assets, with the cash and cash equivalents balances in the cash flow statement. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The new guidance clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The new guidance is effective for the Company beginning after January 1, 2018, including interim periods within those periods. The adoption of this standard is not expected to have a material impact on our consolidated financial statements or disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The new guidance requires only a one-step quantitative impairment test, whereby a goodwill impairment loss will be measured as the excess of a reporting unit’s carrying amount over its fair value (not to exceed the total goodwill allocated to that reporting unit). It eliminates Step 2 of the current two-step goodwill impairment test, under which a goodwill impairment loss is measured by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. For public companies, the amended guidance is effective for the Company beginning after January 1, 2020. The adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting. The new guidance amends the scope of modification accounting for share-based payment arrangements and provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. This standard is effective for the Company beginning January 1, 2018, including interim periods within those periods. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities From Equity (Topic 480) And Derivatves And Hedging (Topic 815): Accounting For Certain Financial Instruments With Down Round Features, Replacement of the Indefinite Deferral For Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests With a Scope Exception. The new guidance changes the classification of certain equity-linked financial instruments (or embedded features) with down round features. The amendments also clarify existing disclosure requirements for equity-classified instruments. For freestanding equity-classified financial instruments, the amendments require entities that present earnings per share (EPS) in accordance with Topic 260, Earnings Per Share, to recognize the effect of the down round feature when it is triggered. That effect is treated as a dividend and as a reduction of income available to common shareholders in basic EPS. Convertible instruments with embedded conversion options that have down round features would be subject to the specialized guidance for contingent beneficial conversion features (in Subtopic 470-20, Debt—Debt with Conversion and Other Options), including related EPS guidance (in Topic 260). The amendments in Part II of this Update recharacterize the indefinite deferral of certain provisions of Topic 480, Distinguishing Liabilities from Equity, that now are presented as pending content in the Codification, to a scope exception. Those amendments do not have an accounting effect. Part I of the new guidance affects any entity that issues financial instruments that include down round features. The amendments in Part I of this Update that relate to the recognition, measurement, and earnings per share of certain freestanding equity-classified financial instruments that include down round features affect entities that present earnings per share in accordance with the guidance in Topic 260, Earnings Per Share. Part I is effective for the Company beginning January 1, 2019 and Part II did not require transition guidance as the amendment did not have an accounting effect. The adoption of this standard is not expected to have a material impact on its consolidated financial statements or disclosures.
