Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Description of Business, Basis of Presentation and Summary of Significant Accounting Policies Angie’s List, Inc. (collectively with its wholly owned subsidiaries, the “Company”) operates a national local services consumer review service and marketplace where members can research, shop for and purchase local services for critical needs, as well as rate and review the providers of these services. Ratings and reviews, which are now available to members free-of-charge, assist members in identifying and hiring a provider for their local service needs. The Company’s services are provided in markets located across the continental United States. Basis of Presentation The consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and reflect all adjustments of a normal recurring nature considered, in the opinion of management, necessary to fairly report the results for the periods presented. Operating Segments Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company manages its business on the basis of one operating segment. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation. Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes as well as the disclosure of contingent assets and liabilities and reported revenue and expenses. Actual results could differ from those estimates. Reclassification of Prior Year Presentation Certain prior year amounts were reclassified for consistency with the current period presentation, including the marketing compensation and personnel-related costs and general marketing operating expenditures that were moved from general and administrative expense and selling expense to marketing expense within the consolidated statements of operations. These reclassifications did not impact net income (loss) previously reported. Significant Accounting Policies Revenue Recognition The Company recognizes revenue when all of the following conditions are met: there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of fees is reasonably assured and the amount of fees to be paid by the customer is fixed or determinable. Membership Revenue. Revenue from the sale of membership subscriptions is generally recognized ratably over the term of the associated subscription. Service Provider Revenue. Revenue from the sale of website, mobile and call center advertising is recognized ratably over the time period the advertisements run. Revenue from the sale of advertising in the Company’s Angie’s List Magazine publication is recognized in the period in which the publication is published and distributed. Revenue from e-commerce vouchers is recognized on a net basis when the voucher is delivered to the purchaser. While the Company is not the merchant of record with respect to its customers for these transactions, it does offer customers refunds in certain circumstances. Accordingly, revenue from e-commerce transactions is recorded net of a reserve for estimated refunds. Deferred Revenue. Deferred revenue includes the unamortized portion of revenue associated with membership and service provider fees for which the Company received payment in advance of services or advertising to be provided. Deferred revenue is recognized as revenue when the related services or advertising are actually provided. Cash and Cash Equivalents The Company maintains its cash in bank deposit accounts and money market funds with contractual maturities of three months or less, which, at times, may exceed federally insured limits. The Company also classifies as cash and cash equivalents any investments in certificates of deposit, U.S. Treasury securities or corporate bonds with contractual maturities of three months or less, which also, at times, may exceed federally insured limits. To date, the carrying values of the Company’s cash and cash equivalents approximate their fair values, and there have been no material losses in these accounts. Short-Term Investments Short-term investments consist of certificates of deposit, U.S. Treasury securities or corporate bonds with maturities of more than 90 days but less than one year, all of which are designated as held-to-maturity investments and recorded at amortized cost, adjusted, as applicable, for amortization of premiums to maturity computed under the effective interest method, in the consolidated balance sheets. Amortization and interest income from held-to-maturity investments are included in interest expense, net, in the consolidated statements of operations. The Company’s objective with respect to these investments is to earn a higher rate of return on funds that are otherwise not anticipated to be required to meet liquidity needs in the near term while maintaining a low level of investment risk with the positive intent and ability to hold these investments to maturity. The Company reviews its investment portfolio for other-than-temporary impairment whenever events or changes in circumstances indicate the carrying amount of the investment may be impaired, considering such factors as the duration, severity and reason for the decline in value as well as the potential recovery period. As of December 31, 2016 and 2015 , the Company held $16,541 and $23,976 , respectively, in short-term investments with no material unrealized gains or losses in these accounts in either year then ended. Accounts Receivable Accounts receivable is stated at the amount billed to service providers, less an estimated allowance for doubtful accounts. The Company performs ongoing credit evaluations and generally requires no collateral from service providers. Management reviews individual accounts as they become past due to determine collectability. The Company’s allowance for doubtful accounts balance is adjusted periodically based on management’s consideration of past due accounts. Individual accounts are charged against the allowance when all reasonable collection efforts are exhausted. The changes in the Company’s allowance for doubtful accounts balances during the years ended December 31, 2016 , 2015 and 2014 were as follows: Year Ended December 31, 2016 2015 2014 Beginning balance $ 1,658 $ 1,651 $ 1,107 Additions, net of recoveries 7,404 5,746 5,028 Deductions (5,766 ) (5,739 ) (4,484 ) Ending balance $ 3,296 $ 1,658 $ 1,651 Property, Equipment and Software Assets recorded as property, equipment and software are stated at cost and depreciated over their respective estimated useful lives. The Company also capitalizes certain costs related to website and software acquisition and development for internal use, including internal labor costs incurred during development. Construction in progress is comprised of costs incurred related to the construction or development of property, equipment and software that is not ready for its intended use and therefore not yet placed in service. The Company’s estimated useful lives for property, equipment and software generally range from 3 to 25 years . Depreciation/amortization is computed using the straight-line method. Repairs and routine maintenance are charged to expense as incurred. In accordance with authoritative guidance, the Company begins to capitalize website and software development costs for internal use when planning and design efforts are successfully completed and development is ready to commence. Costs incurred during planning and design, together with costs incurred for training and maintenance, are expensed as incurred and recorded in product and technology expense within the consolidated statements of operations. The Company places capitalized website and software development assets into service and commences depreciation/amortization when the applicable project or asset is substantially complete and ready for its intended use. Once placed into service, the Company capitalizes qualifying costs of specified upgrades or enhancements to capitalized website and software development assets when the upgrade or enhancement will result in new or additional functionality. The Company capitalizes internal labor costs, including compensation, benefits and payroll taxes, incurred for certain capitalized website and software development projects related to the Company’s technology platform. The Company’s policy with respect to capitalized internal labor stipulates that labor costs for employees working on eligible internal use capital projects are capitalized as part of the historical cost of the project when the impact, as compared to expensing such labor costs, is material. The Company also capitalized a portion of the interest on funds borrowed in relation to the development of the Company’s technology platform. The Company’s policy with respect to capitalized interest specifies that interest costs on eligible long-term internal use capital projects are capitalized as part of the historical cost of the project when the impact, as compared to expensing such interest costs, is material. Goodwill Goodwill is not amortized and is instead reviewed for impairment, at a minimum, on an annual basis as of December 31, or more frequently should an event or circumstance occur that indicates the carrying amount of goodwill may be impaired. If goodwill is considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the goodwill exceeds its fair market value. To date, no impairment of goodwill has been identified or recognized. Data Acquisition Costs Data acquisition costs consist of external costs related to acquiring consumer reports on service providers. These reports are used by the Company to provide its members with feedback on service providers. Amortization is computed using the straight-line method over the period during which the information is expected to benefit the Company’s members, which is estimated to be three years. The capitalized costs are included in intangible assets in the consolidated balance sheets, and the amortized expense is reflected within operations and support expense in the consolidated statements of operations. Long-Lived Assets Long-lived assets, including property, equipment and software and amortizable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to future net undiscounted cash flows expected to be generated by the related asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount exceeds the fair market value of the assets. Long-lived asset impairment charges were recorded during the second and fourth quarters of 2015 as discussed in further detail in Note 5, “Property, Equipment and Software,” of these Notes to Consolidated Financial Statements. Deferred Financing Fees As a result of the Company’s entry into a new financing agreement in September 2014, the Company incurred financing costs that were capitalized as a deferred financing fee asset. As further discussed below, upon adoption of the guidance set forth under Accounting Standards Update No. 2015-03, effective January 1, 2016, the Company reclassified the deferred financing fees previously recorded in other noncurrent assets to net long-term debt in the consolidated balance sheets. The deferred financing fees contra liability is offsetting the gross term loan balance and is being amortized to interest expense on a straight-line basis over the term of the financing agreement. The Company’s long-term debt balance is reported net of the remaining unamortized deferred financing fees within the consolidated balance sheets. In connection with the extinguishment of the Company’s previous loan and security agreement during the course of the aforementioned financing transaction, the Company expensed the remaining unamortized portion of the capitalized deferred financing fees associated with the previous loan and security agreement in 2014, and the related amount was included in the loss on debt extinguishment within the consolidated statement of operations for the year ended December 31, 2014. Fees Paid to Lender The Company incurred financing costs in the form of fees paid directly to the lender during the completion of its September 2014 debt financing transaction and in connection with the execution of the second amendment to the financing agreement in November 2016. In accordance with the applicable authoritative guidance, these fees were recorded as a contra liability, offsetting the gross term loan balance. The fees paid to lender contra liability is being amortized to interest expense on a straight-line basis over the term of the financing agreement. The Company’s long-term debt balance is reported net of the remaining unamortized fees paid to the lender within the consolidated balance sheets. Leases The Company leases office space pursuant to long-term non-cancellable operating leases expiring through 2021. Rent expense is recognized on a straight-line basis over the expected lease term. Certain of the Company’s leases contain provisions for tenant improvement allowances, which are recorded as a deferred rent liability and amortized over the term of the associated lease as an offset to rent expense each period. Leasehold improvements are capitalized to property, equipment and software and depreciated on a straight-line basis over the corresponding estimated useful lives. Sales Commissions Commissions expense from the sale of service provider advertisements is recognized ratably over the term of the associated advertisement. The Company defers the recognition of commission expense until such time as the revenue related to the contract for which the commission was paid is recognized. Deferred commissions for each contract are amortized to expense in a manner consistent with how revenue is recognized for each contract, resulting in straight-line recognition of expense over the contractual term. Unamortized commission expense of $8,869 and $8,573 as of December 31, 2016 and 2015 , respectively, is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets. Marketing Expense Marketing expense consists of national television, radio and print advertising as well as online digital advertising. The Company generally expenses advertising costs as incurred. The Company recorded advertising spend of $46,056 , $71,534 and $87,386 as a component of marketing expense in the consolidated statements of operations for the years ended December 31, 2016 , 2015 and 2014 , respectively. Stock-Based Compensation The Company accounts for stock-based compensation expense using the fair value measurement and recognition provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 718, Stock Compensation . For awards of stock options, restricted stock units (“RSUs”) and certain performance awards of restricted stock units (“PRSUs”), the Company recognizes stock-based compensation expense over the requisite service period in an amount equal to the fair market value on the grant date of the respective award. For PRSUs granted subject to the Company’s performance in relation to predetermined performance conditions, the Company recognizes stock-based compensation expense over the vesting period based on the projected probability of achievement of the performance conditions as of the end of each reporting period during the performance period and may periodically adjust the recognition of such expense, as necessary, in response to any changes in the Company’s forecasts with respect to the performance conditions. The fair value of stock options is estimated at the date of grant using the Black-Scholes option-pricing model utilizing the historical weighted-average assumptions outlined in Note 11, “Stock-Based Compensation,” of these Notes to Consolidated Financial Statements. The fair value of RSUs, as well as PRSUs granted subject to the Company’s performance in relation to predetermined performance conditions, is based on the fair market value of the underlying stock on the date of grant. The fair value of PRSUs contingent upon the performance of the Company’s stock price in relation to certain predetermined thresholds is estimated as of the date of grant using a Monte Carlo option-pricing simulation model. Effective January 1, 2016, the Company began utilizing its own historical data for the volatility input to the calculation of the estimated fair value of stock option awards as there is now sufficient historical volatility data available to do so. Additionally, in connection with the adoption of ASU 2016-09 during the third quarter of 2016, the Company elected to commence accounting for forfeitures of share-based payment awards as they occur instead of recognizing stock-based compensation expense net of estimated forfeitures. Loss Contingencies The Company is involved in various lawsuits, claims, investigations and other legal and regulatory proceedings, both as a plaintiff and as a defendant, related to its business and operations. The Company records a liability when it is both probable a loss has been incurred and the amount can be reasonably estimated. If the Company determines a loss is possible and a range of loss can be reasonably estimated, the Company discloses the range of the possible loss in these Notes to Consolidated Financial Statements. Significant judgment is required to determine the probability or possibility, as well as the estimated amount, as applicable, of a loss contingency. On at least a quarterly basis, as necessary, the Company reviews and evaluates developments with respect to legal matters that could impact the amount of an associated liability previously accrued, as well as the related ranges of possible losses disclosed, and makes adjustments and changes as appropriate. Loss on Debt Extinguishment The penalties, additional interest and other fees and expenses incurred in connection with the prepayment of the Company’s previous debt facility in September 2014, together with the amounts related to the write-off of the previous deferred financing fees and recognition of the remaining interest expense under the previous debt facility, were included within the loss on debt extinguishment contained in the consolidated statement of operations for the year ended December 31, 2014. Sales and Use Tax Currently, the Company does not separately collect sales and use taxes from its members. Instead, the Company reports and, if applicable, pays sales and use taxes on behalf of its members in certain jurisdictions and records an accrual for sales and use tax based on probable liability within other applicable jurisdictions. Sales and use tax expenses are included within operations and support expense in the consolidated statements of operations. Income Taxes The Company is subject to corporate federal and state income taxes at prevailing corporate rates and accounts for income taxes and the related accounts using the asset and liability method in accordance with ASC 740, Income Taxes . Under this method, the Company accrues income taxes payable or refundable and recognizes deferred tax assets and liabilities based on differences between the book and tax basis of assets and liabilities. The Company measures deferred tax assets and liabilities using enacted rates in effect for the years in which the differences are expected to reverse and recognizes the effect of a change in enacted rates in the period of enactment. After determining the total amount of deferred tax assets, the Company determines whether it is more likely than not that some portion of the deferred tax assets will not be realized. If the Company determines a deferred tax asset is not likely to be realized, a valuation allowance is established against that asset to record it at its expected realizable value. The Company periodically reviews deferred tax assets for recoverability based on historical taxable income, projected future taxable income and the expected timing of reversals of existing temporary differences. Should there be a change in the ability to recover deferred tax assets, the tax provision would be adjusted in the period in which the assessment changed. The Company establishes assets and liabilities for uncertain positions taken or expected to be taken in income tax returns using a more-likely-than-not recognition threshold. The Company includes in income tax expense any interest and penalties related to uncertain tax positions. Pledged Assets The Company’s obligations under the long-term debt financing agreement are guaranteed by each of the Company’s subsidiaries and are secured by first priority interests in all of the Company’s respective assets and a pledge of the equity interests of the Company’s subsidiaries. Recent Accounting Pronouncements - Adopted As of January 1, 2016, the Company adopted FASB Accounting Standards Update No. 2015-03: Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , which set forth a requirement that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that liability, resulting in the Company reclassifying the deferred financing fees previously recorded in other noncurrent assets, amounting to $1,462 as of December 31, 2015, to net long-term debt in the consolidated balance sheets. As of August 1, 2016, the Company adopted FASB Accounting Standards Update No. 2016-09: Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which simplified several aspects of the accounting guidance for employee share-based payment transactions, including accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance requires companies to record excess tax benefits and tax deficiencies as income tax benefit or expense in the statement of operations when share-based payment awards vest or are settled. Upon adoption, the Company’s previously unrecognized excess tax benefits were recorded as a deferred tax asset, which was fully offset by a valuation allowance. Without the valuation allowance, the Company’s deferred tax asset would have increased by $2,406 . Additionally, under the new guidance, the Company elected to begin accounting for forfeitures of share-based payment awards as they occur in lieu of the previous practice of estimating the number of awards expected to be forfeited and adjusting the estimate when it was no longer probable that the corresponding service condition would be fulfilled. As ASU 2016-09 was adopted as of an interim date, the Company recorded a modified retrospective transition adjustment as of the beginning of 2016 during the third quarter to reflect an increase in stock-based compensation expense of $804 related to the forfeitures election. No changes in presentation or classification in the statement of cash flows were required in connection with the adoption of ASU 2016-09, and the Company is now allowing share withholding for taxes upon the vesting of RSUs and PRSUs in excess of the minimum statutory tax withholding requirements, as permitted by ASU 2016-09. Recent Accounting Pronouncements - Not Yet Adopted In January 2017, the FASB issued Accounting Standards Update No. 2017-04: Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). The amendments in this update simplify the accounting for goodwill impairments by eliminating step 2 from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to the reporting unit. ASU 2017-04 will be effective for the Company in fiscal year 2020, but early adoption is permitted. The Company is currently evaluating the impact of this update on the consolidated financial statements. In August 2016, the FASB issued Accounting Standards Update No. 2016-15: Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The amendments in this update add to or clarify existing U.S. GAAP guidance on the classification of certain cash receipts and payments in the statement of cash flows. ASU 2016-15 will be effective for the Company in fiscal year 2018, but early adoption is permitted. The guidance set forth in this update must be applied retrospectively to all periods presented but may be applied prospectively if retrospective application would be impracticable. The Company is currently evaluating the impact of this update on the consolidated financial statements. In June 2016, the FASB issued Accounting Standards Update No. 2016-13: Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The amendments in this update add to U.S. GAAP a current expected credit loss impairment model that is based on expected losses rather than incurred losses, requiring consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. ASU 2016-13 is also intended to reduce the complexity of U.S. GAAP by decreasing the number of credit impairment models that entities use to account for debt instruments. ASU 2016-13 will be effective for the Company in fiscal year 2020, but early adoption is permitted beginning in 2019. The Company is currently evaluating the impact of this update on the consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02: Leases (Topic 842) (“ASU 2016-02”). The amendments in this update require lessees, among other things, to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous authoritative guidance. This update also introduces new disclosure requirements for leasing arrangements. ASU 2016-02 will be effective for the Company in fiscal year 2019, but early adoption is permitted. The Company is currently evaluating the impact of this update on the consolidated financial statements. In January 2016, the FASB issued Accounting Standards Update No. 2016-01: Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). The amendments in this update address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. In particular, the amendments in this update supersede, for public business entities, the requirement to disclose the methods and significant assumptions used in calculating the fair value of financial instruments required to be disclosed for financial instruments measured at amortized cost on the balance sheet. ASU 2016-01 will be effective for the Company in fiscal year 2018, but early adoption is permitted. The Company does not believe that the adoption of the guidance set forth in this update will have a material impact on the consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09: Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). This update outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” This update also requires significantly expanded disclosures related to revenue recognition. In March 2016, the FASB issued Accounting Standards Update No. 2016-08: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”) , amending the principal-versus-agent implementation guidance set forth in ASU 2014-09. Among other things, ASU 2016-08 clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued Accounting Standards Update No. 2016-10: Identifying Performance Obligations and Licensing (“ASU 2016-10”), which amends certain aspects of the guidance set forth in the FASB’s new revenue standard related to identifying performance obligations and licensing implementation. In May 2016, the FASB issued Accounting Standards Update No. 2016-12: Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”), amending certain aspects of ASU 2014-09 to address implementation issues identified by the FASB’s transition resource group and clarify the new revenue standard’s core revenue recognition principles. In December 2016, the FASB issued Accounting Standards Update No. 2016-20: Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”), which clarified or corrected unintended application of certain aspects of the guidance set forth under ASU 2014-09. ASU 2014-09 will be effective for the Company in fiscal year 2018 following the issuance of Accounting Standards Update No. 2015-14: Deferral of the Effective Date in August 2015, which deferred the effective date of ASU 2014-09 by one year. The Company currently anticipates adopting the new revenue recognition standard effective January 1, 2018 utilizing the modified retrospective method of adoption. Accordingly, upon adoption, the Company currently anticipates recognizing the cumulative effect of adopting this guidance as an adjustment to the opening balance of the accumulated deficit within the consolidated balance sheet for the period of adoption, and prior periods will not be retrospectively adjusted. The Company identified the following revenue streams that will be further evaluated in detail based on the criteria established under the new revenue standard: membership revenue, service provider advertising revenue and service provider e-commerce revenue. The Company is still in the process of evaluating the impact of these updates on the consolidated financial statements and related disclosures.

Earnings Per Share [Abstract]
Net Income (Loss) Per Common Share	Net Income (Loss) Per Common Share Basic and diluted net income (loss) per common share are computed by dividing consolidated net income (loss) by the basic and diluted weighted-average number of common shares outstanding, respectively, for the period. Basic net income (loss) per common share was $(0.13) , $0.18 and $(0.21) for the years ended December 31, 2016 , 2015 and 2014 , respectively. Diluted net income (loss) per common share was $(0.13) , $0.17 and $(0.21) for the years ended December 31, 2016 , 2015 and 2014 , respectively. The following table shows the calculation of the diluted weighted-average number of common shares outstanding: December 31, 2016 2015 2014 Weighted-average number of common shares outstanding — basic 58,860,152 58,520,546 58,510,106 Total dilutive effect of outstanding share-based payments — 262,343 — Weighted-average number of common shares outstanding — diluted 58,860,152 58,782,889 58,510,106 The following potentially dilutive outstanding share-based payments were not included in the diluted net income (loss) per common share calculations as the impact would have been antidilutive for the periods presented: December 31, 2016 2015 2014 Stock options 6,817,996 6,477,872 5,438,897 Restricted stock units 1,699,053 1,128,826 — Performance awards of restricted stock units 3,087,949 778,829 — Shares to be purchased under employee stock purchase plan 2,829 — — See Note 11, “Stock-Based Compensation,” of these Notes to Consolidated Financial Statements for additional detail and discussion regarding the Company’s share-based payment awards and employee stock purchase plan. The PRSUs granted during 2016 (the “2016 LTIP”) that remained outstanding as of December 31, 2016 were not included in the computation of diluted net income (loss) per common share as the number of shares that will ultimately be issued is contingent upon the Company’s achievement of certain predetermined performance conditions and does not meet the criteria for inclusion per the applicable U.S. GAAP guidance.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Whenever possible, quoted prices in active markets are used to determine the fair value of the Company’s financial instruments. The Company’s financial instruments are not held for trading or other speculative purposes. The estimated fair value of financial instruments was determined using available market information and appropriate valuation methodologies. However, considerable judgment is required in interpreting market data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize in a current market exchange. The use of different market assumptions and/or estimation methodologies may materially impact the estimated fair value amounts. Fair Value Hierarchy Fair value is based on the price that would be received upon sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In accordance with ASC 820, Fair Value Measurement (“ASC 820”), the Company categorized the financial assets and liabilities that are adjusted to fair value based on the priority of the inputs to the valuation technique, following the three-level fair value hierarchy prescribed by ASC 820, as follows: Level 1: Quoted prices (unadjusted) in active markets that are accessible at the measurement date for assets or liabilities. Level 2: Observable prices that are based on inputs not quoted on active markets but corroborated by market data. Level 3: Unobservable inputs that are used when little or no market data is available. Valuation Techniques The Company’s money market fund investments, the maturities for which are less than 90 days, are classified as cash equivalents within Level 1 of the fair value hierarchy on the basis of valuations using quoted market prices. Short-term investments consist of certificates of deposit, corporate bonds and U.S. Treasury securities with maturities of more than 90 days but less than one year. As many fixed income securities do not trade daily, fair values are often derived using recent trades of securities with similar features and characteristics. When recent trades are not available, pricing models are used to determine these prices. These models calculate fair values by discounting future cash flows at estimated market interest rates. Such market rates are derived by calculating the appropriate spreads over comparable U.S. Treasury securities, based on the credit quality, industry and structure of the asset. Typical inputs and assumptions to pricing models include, but are not limited to, a combination of benchmark yields, reported trades, issuer spreads, liquidity, benchmark securities, bids, offers, reference data and industry and economic events. The Company’s fixed income certificates of deposit, U.S. Treasury securities and corporate bond investments with fixed maturities are valued using recent trades or pricing models and are therefore classified within Level 2 of the fair value hierarchy. Recurring Fair Value Measurements There were no movements between fair value measurement levels for the Company’s cash equivalents and investments during 2016 or 2015 , and there were no material unrealized gains or losses in these accounts as of December 31, 2016 or 2015 . The following tables summarize the Company’s financial instruments at fair value based on the fair value hierarchy for each class of instrument as of December 31, 2016 and 2015 : Fair Value Measurement at December 31, 2016 Using Carrying Value at December 31, 2016 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash equivalents: Money market funds $ 2,419 $ 2,419 $ — $ — Investments: Certificates of deposit 13,840 — 13,837 — U.S. Treasury securities 2,701 — 2,702 — Total assets $ 18,960 $ 2,419 $ 16,539 $ — Fair Value Measurement at December 31, 2015 Using Carrying Value at December 31, 2015 Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Cash equivalents: Money market funds $ 970 $ 970 $ — $ — Investments: Certificates of deposit 19,310 — 19,292 — U.S. Treasury securities 3,652 — 3,649 — Corporate bonds 1,014 — 1,013 — Total assets $ 24,946 $ 970 $ 23,954 $ — The Company did not recognize any other-than-temporary impairment losses for the years ended December 31, 2016 , 2015 , or 2014 . The carrying amount of the term loan approximates fair value, using Level 2 inputs, as this borrowing bears interest at a variable (market) rate at December 31, 2016 and 2015 . Non-Recurring Fair Value Measurements The Company has certain assets that are measured at fair value on a non-recurring basis under circumstances and events, including those described in Note 5, “Property, Equipment and Software,” and Note 6, “Goodwill and Amortizable Intangible Assets,” of these Notes to Consolidated Financial Statements that are adjusted to fair value in certain circumstances when the carrying values are more than the fair values. The categorization of the framework used to price the assets in the event of an impairment is considered a Level 3 measurement due to the subjective nature of the unobservable inputs used to determine the fair value. Assets and liabilities acquired in business combinations are recorded at their fair value as of the date of acquisition using Level 2 and Level 3 inputs. The carrying amounts of accounts receivable and accounts payable reported in the consolidated balance sheets approximate fair value.

On June 10, 2016, the Company entered into a first amendment to the financing agreement which, among other things, (i) extended the commencement of the Company’s quarterly repayment obligations under the term loan from September 30, 2016 to September 30, 2017; (ii) revised the financial covenants for minimum consolidated EBITDA, as defined in the financing agreement, for periods ending after June 30, 2016; (iii) revised the financial covenant related to minimum required liquidity from $10,000 to $30,000 ; (iv) removed the financial covenant related to minimum membership revenue for periods ending after March 31, 2016; and (v) modified the basis for the calculation of the applicable interest rate. On November 1, 2016, the Company entered into a second amendment to the financing agreement which, among other things, (i) added a new financial covenant related to consolidated active service provider contract value beginning with the period ending December 31, 2016; (ii) revised the financial covenants for minimum consolidated EBITDA, as defined in the financing agreement and subsequently modified under the second amendment, for periods ending after September 30, 2016; (iii) revised the financial covenant related to minimum required liquidity; (iv) modified the basis for the calculation of the applicable interest rate; (v) modified the dates under which the prepayment premium is applicable; and (vi) modified certain terms related to the delayed draw term loan. Additionally, the second amendment set forth a fee to be paid by the Company to the lender, in three equal annual installments, in connection with the execution of the amendment, and this fee was capitalized along with the existing unamortized fees paid to lender contra liability and is being amortized to interest expense over the remaining term of the financing agreement. The financing agreement requires monthly interest payments on the first business day of each month until maturity on any principal amounts outstanding under either debt facility. In accordance with the second amendment to the financing agreement, if the Company’s consolidated EBITDA for the trailing four consecutive fiscal quarters is less than $20,000 or the Company’s qualified cash, as defined in the financing agreement, is less than $20,000 as of the applicable period end, amounts outstanding under the financing agreement bear interest at a per annum rate, at the option of the Company, equal to (i) the LIBOR rate for the interest period in effect, subject to a floor of 0.5% , plus 9.50% or (ii) the reference rate, which is based on the prime rate as published by the Wall Street Journal, subject to a floor of 3.25% , plus 8.50% . If the Company’s qualified cash is greater than $20,000 , and the Company’s consolidated EBITDA for the trailing four consecutive fiscal quarters is: • greater than $20,000 but less than $25,000 , the applicable LIBOR interest rate is 8.5% , and the applicable reference interest rate is 7.5% ; • greater than $25,000 but less than $30,000 , the applicable LIBOR interest rate is 7.5% , and the applicable reference interest rate is 6.5% ; or • greater than $30,000 , the applicable LIBOR interest rate is 6.5% , and the applicable reference interest rate is 5.5% .

The Company is required to make principal payments on the outstanding balance of the delayed draw term loan equal to 1.25% of the amount of such loan funded at or prior to the last day of each calendar quarter and to repay the remaining outstanding balance of the delayed draw term loan at maturity. From the effective date of the financing agreement through September 26, 2017, the Company is also required to pay a commitment fee equal to 0.75% per annum of the unborrowed amounts of the delayed draw term loan. The Company may prepay the amounts outstanding under the financing agreement at any time and is required to prepay the loans with (i) the net proceeds of certain asset sales, issuances of debt or equity, and certain casualty events, and (ii) up to 50% of consolidated excess cash flow, as defined in the financing agreement, for each fiscal year during the term of the financing agreement, commencing with the year ended December 31, 2015.

The Company’s obligations under the financing agreement are guaranteed by each of its subsidiaries and are secured by first priority security interests in all of their respective assets and a pledge of the equity interests of the Company’s subsidiaries. The term loan and the delayed draw term loan mature on September 26, 2019. As of December 31, 2016 , the Company had $57,642 in outstanding borrowings under the term loan, net of unamortized deferred financing fees of $1,071 and unamortized fees paid to the lender of $1,287 , both of which are being amortized into interest expense over the term of the financing agreement, and availability of $25,000 under the delayed draw term loan. Principal amounts due over the remaining term of the financing agreement as of December 31, 2016 are as follows: $1,500 in 2017 , $3,000 in 2018 and $55,500 in 2019 . The financing agreement contains various restrictive covenants, including restrictions on the Company’s ability to dispose of assets, make acquisitions or investments, incur debt or liens, make distributions to stockholders or repurchase outstanding stock, enter into related-party transactions and make capital expenditures, other than upon satisfaction of the conditions set forth in the financing agreement. The Company is also required to comply with certain financial covenants, including minimum consolidated EBITDA, as defined in the financing agreement and subsequently modified under the second amendment, minimum liquidity, minimum consolidated active service provider contract value and maximum consolidated capital expenditures. Upon an event of default, which includes certain customary events such as, among other things, a failure to make required payments when due, a failure to comply with covenants, certain bankruptcy and insolvency events, defaults under other material indebtedness, or a change in control, the lenders may accelerate amounts outstanding, terminate the agreement and foreclose on all collateral. The Company was in compliance with all financial and non-financial covenants at December 31, 2016 .

As of December 31, 2016 , the estimated future minimum lease payments under long-term non-cancellable operating leases for each of the next five years and thereafter are as follows: 2017 $ 2,134 2018 2,093 2019 2,141 2020 736 2021 8 Thereafter — Total future minimum lease payments $ 7,112 Rent expense under the Company’s operating leases totaled $1,892 , $1,997 and $1,643 in 2016 , 2015 and 2014 , respectively. Legal Matters The Company is regularly involved in litigation, both as a plaintiff and as a defendant, relating to its business and operations. The Company assesses the likelihood of any judgments or outcomes with respect to these matters and determines loss contingency assessments on a gross basis after assessing the probability of incurrence of a loss and whether a loss is reasonably estimable. In addition, the Company considers other relevant factors that could impact its ability to reasonably estimate a loss. A determination of the amount of reserves required, if any, for these contingencies is made after analyzing each matter. The Company’s reserves may change in the future due to new developments or changes in strategy in handling these matters. Although the results of litigation and claims cannot be predicted with certainty, the Company currently believes the final outcome of the matters listed below will not have a material adverse effect on its business, consolidated financial position, results of operations or cash flows. Regardless of the outcome, litigation can adversely impact the Company as a result of defense and settlement costs, diversion of management resources and other factors. Moore, et al. v. Angie’s List, Inc., 2:15cv-01243-SD. On March 11, 2015, a lawsuit seeking class action status was filed against the Company in the U.S. District Court for the Eastern District of Pennsylvania. The lawsuit alleged claims for breaches of contract and the covenant of good faith and fair dealing, fraud and fraudulent inducement, unjust enrichment and violation of Pennsylvania’s Unfair Trade Practices and Consumer Protection Law premised on the allegations that the Company does not disclose that it accepts advertising payments from service providers or that the payments allegedly impact the service provider letter-grade ratings, the content and availability of reviews about the provider and the provider’s place in search-result rankings. The Company filed a motion to dismiss on May 13, 2015, which was granted in part on August 7, 2015. In particular, the plaintiff’s claims for breach of the covenant of good faith and fair dealing and unjust enrichment were dismissed from the action. On April 19, 2016, the parties agreed to settle the claims on a class-wide basis. Among other relief, the settlement provided for a cash payment of up to $2,350 to create a fund for the payment of cash to settlement class members and for the payment of plaintiffs’ attorneys’ fees and costs as approved by the Court. Settlement class members were given the option of sharing in the cash fund or selecting a free period of membership of up to four months depending on the date and length of their membership with Angie’s List. The settlement also provided certain prospective relief in the form of enhanced explanations in the Company’s membership agreement and in responses to frequently asked questions concerning, among other things, the advertising revenue earned from service providers. The Company recorded a $3,500 contingent liability related to this matter in the first quarter of 2016, and this amount included the estimated cost of the cash fund described above as well as the payment of reasonable notice and administration costs, attorneys’ fees and an assumption of revenue the Company would forego as a result of certain class members selecting the option for a free period of membership. On December 12, 2016, the Court entered an order granting final approval of the settlement. One class member appealed the order, but the plaintiff settled with the class member, and the class member stipulated to dismiss the appeal. On January 13, 2017, the Third Circuit Court of Appeals entered an order dismissing the appeal, and the settlement became final and effective as of that date. The Company, with the assistance of its third-party settlement administrator, is now in the process of administering the settlement by making the above-referenced enhanced explanations regarding advertising revenue earned from service providers, by making the above-referenced cash payment into an escrow account that will be appropriately paid to the class members who selected the cash class benefit and to plaintiffs’ counsel and by providing instructions on how to redeem membership extensions to the class members who selected the membership extension class benefit. The aforementioned contingent legal liability was subsequently reduced by $671 following completion of the election period for settlement class members during the fourth quarter. The Company’s accrual for this matter was $2,601 as of December 31, 2016. Williams, et al. v. Angie’s List, Inc., 1:16-cv-878 . On April 20, 2016, a group of former employees filed a lawsuit in the United States District Court for the Southern District of Indiana. The lawsuit alleges the Company failed to pay (i) wages earned in a timely manner as required under Indiana Wage Statutes and (ii) overtime wages in violation of the Fair Labor Standards Act (29 U.S.C. §§ 206-07) and is requesting payment of all damages, including unpaid wages, interest, attorneys’ fees and other charges. First and second amended complaints were filed, adding additional named plaintiffs, and the Company’s answer to the second amended complaint was filed on July 26, 2016. The plaintiffs filed a motion for conditional certification on June 10, 2016, and the Company filed its response brief in opposition on July 15, 2016. The Court denied the plaintiffs’ motion for conditional certification on November 30, 2016 but allowed the plaintiffs to refile with a more narrow class definition. On December 9, 2016, the plaintiffs filed a renewed motion for conditional certification. The Company filed its response to the renewed motion on January 6, 2017, and the plaintiffs filed their reply on January 17, 2017. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability, if any, related to this matter, and accordingly, has not established any reserve for this matter. Crabtree, et al. v. Angie’s List, Inc., 1:16-cv-877 . On April 20, 2016, three former employees filed a lawsuit in the United States District Court for the Southern District of Indiana. The lawsuit alleges the Company failed to pay (i) wages earned in a timely manner as required under Indiana Wage Statutes and (ii) overtime wages in violation of the Fair Labor Standards Act (29 U.S.C. §§ 206-07) and is requesting payment of all damages, including unpaid wages, interest, attorneys’ fees and other charges. The plaintiffs filed a first amended complaint in May 2016, adding one additional Indiana wage statute claim. The Company filed its answer and defenses on June 9, 2016. Discovery with respect to this matter is ongoing. The Company is currently unable to determine the likely outcome or reasonably estimate the amount or range of potential liability, if any, related to this matter, and accordingly, has not established any reserve for this matter.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation In April 2010, the Company adopted an Omnibus Incentive Plan (“Incentive Plan”) in order to provide stock-based compensation to executive officers, directors and certain other employees. The Incentive Plan was amended and restated effective August 2011, increasing the number of shares issuable to 5,090,496 . In each year since, additional shares of stock were reserved for issuance, bringing the total available shares issuable to 19,609,325 . As of December 31, 2016 , there were 16,621,491 shares of common stock reserved under the Incentive Plan, of which 1,213,290 shares remained available for future grants. To date, the Company has granted stock options, restricted stock units (“RSUs”) and performance awards of restricted stock units (“PRSUs”) under the Incentive Plan, the latter two of which were issued for the first time during 2015. In connection with the adoption of ASU 2016-09 in August 2016, the Company elected to begin accounting for forfeitures of share-based payment awards as they occur in lieu of the Company’s previous practice of estimating the number of awards expected to be forfeited and adjusting the estimate when it was no longer probable that the corresponding service condition would be fulfilled. Stock Options A summary of stock option activity under the Incentive Plan as of December 31, 2016 and 2015 and changes during the years then ended is as follows: Number of Shares Weighted-Average Weighted-Average Aggregate (in years) (in thousands) Outstanding at December 31, 2014 5,438,897 $ 13.09 8.59 $ 21 Granted 3,026,780 6.30 Exercised (87,601 ) 7.70 Forfeited/Cancelled (1,900,204 ) 12.18 Outstanding at December 31, 2015 6,477,872 $ 10.26 8.24 $ 9,383 Granted 1,463,051 8.74 Exercised (268,931 ) 7.62 Forfeited/Cancelled (675,707 ) 9.26 Outstanding at December 31, 2016 6,996,285 $ 10.14 7.29 $ 4,469 Number of Shares Weighted-Average Weighted-Average Aggregate (in years) (in thousands) Vested and Exercisable at December 31, 2015 2,211,094 $ 12.09 7.18 $ 1,345 Unvested at December 31, 2015 4,266,778 9.32 8.34 Vested and Exercisable at December 31, 2016 3,269,095 $ 11.57 6.12 $ 1,399 Unvested at December 31, 2016 3,727,190 8.89 7.61 Stock options are awarded with an exercise price equal to the market close price on the date of grant. The contractual terms of stock options expire ten years from the grant date and generally vest over a period of four years . The fair value of stock options on the date of grant as determined using the Black-Scholes option-pricing model is amortized on a straight-line basis over the requisite service period. The aggregate intrinsic value shown in the tables above is calculated using the difference between the exercise price of the underlying stock options and the closing price of the Company’s stock on each respective date presented. The fair value of stock options granted is estimated at the date of grant using the Black-Scholes option-pricing model, utilizing the following weighted-average assumptions for the years ended December 31, 2016 , 2015 and 2014 : Year of Grant Risk-Free Dividend Expected Volatility (in years) 2014 1.67% 0% 5.00 53.0% 2015 1.48% 0% 5.00 53.1% 2016 1.26% 0% 5.00 64.6% The risk-free interest rate is based on yields of U.S. Treasury securities with a maturity similar to the estimated expected term of the stock options. The dividend yield assumption is based on the fact that the Company does not have a history of issuing dividends and does not anticipate issuing dividends in the near term. The expected term represents the period of time the stock options are expected to be outstanding based on historical experience. Prior to 2016, the expected volatility assumption was estimated based on historical volatilities for publicly traded common stock of comparable peer companies with similarities in size, lines of business, market capitalization, revenue or financial leverage over the estimated expected life of the stock options. As the Company believes there is now sufficient historical data available with respect to the volatility of its common stock, effective January 1, 2016, the expected volatility assumption was based on the Company’s own historical volatility. The weighted-average grant date fair value of stock options granted during 2016 , 2015 and 2014 was $4.76 , $2.95 and $5.12 per share, respectively. The total intrinsic value of stock options exercised during 2016 , 2015 and 2014 was $428 , $133 and $456 , respectively. The Company recognized stock-based compensation expense of $8,114 , $7,321 and $7,889 in the consolidated statements of operations related to stock options in 2016 , 2015 and 2014 , respectively. As of December 31, 2016 , total unrecognized stock-based compensation expense related to unvested stock options was $11,559 , which will be recognized over the remaining weighted-average life of the awards, 2.30 years. Restricted Stock Units A summary of RSU activity under the Incentive Plan for the years ended December 31, 2016 and 2015 and changes during the years then ended is as follows: RSUs Number of Shares Weighted-Average Grant Date Fair Value Unvested at December 31, 2014 — $ — Granted 1,440,645 6.06 Vested — — Forfeited/Cancelled (225,731 ) 6.54 Unvested at December 31, 2015 1,214,914 $ 5.97 Granted 1,823,767 8.50 Vested (434,619 ) 6.35 Forfeited/Cancelled (400,003 ) 7.74 Unvested at December 31, 2016 2,204,059 $ 7.66 RSUs are measured based on the fair market value of the underlying stock on the date of grant. RSUs generally vest over a period of four years from the grant date and are amortized on a straight-line basis over the requisite service period. Once vested, shares will generally either be issued net of the applicable tax withholding requirements to be paid by the Company on behalf of employees, or a portion of the shares issued will subsequently be sold by employees to satisfy the tax obligations created by the vesting of RSUs. The Company recognized stock-based compensation expense of $4,756 , $973 and $0 in the consolidated statements of operations related to RSUs in 2016 , 2015 and 2014 , respectively. As of December 31, 2016 , total unrecognized stock-based compensation expense related to unvested RSUs was $13,922 , which will be recognized over the remaining weighted-average life of the awards, 3.05 years . Performance Awards of Restricted Stock Units A summary of PRSU activity under the Incentive Plan for the years ended December 31, 2016 and 2015 and changes during the years then ended is as follows: PRSUs Number of Shares Weighted-Average Grant Date Fair Value Unvested at December 31, 2014 — $ — Granted 955,084 2.95 Vested — — Forfeited/Cancelled — — Unvested at December 31, 2015 955,084 $ — Granted 3,034,329 6.55 Vested (298,466 ) 3.68 Forfeited/Cancelled (286,256 ) 6.55 Unvested at December 31, 2016 3,404,691 $ 5.79 The Company’s President and Chief Executive Officer, Scott A. Durchslag, was granted 955,084 PRSUs on September 8, 2015 under the Incentive Plan. The PRSUs, which are market condition performance share-based payment awards, consist of four tranches, each with separate performance criteria based upon the Company’s achievement of certain predetermined stock price thresholds. The PRSUs were measured on the date of grant using a Monte Carlo option-pricing simulation model. The first and second PRSU tranches were earned during 2015, prior to the first anniversary of the grant date, and commenced vesting during 2016, one-half upon the first anniversary of the grant date and the remaining one-half ratably on a quarterly basis over a one -year period thereafter. PRSUs earned subsequent to the first anniversary of the grant date will vest one-half upon achievement of the corresponding stock price target, and the remaining one-half will vest ratably on a quarterly basis over a one -year period thereafter. No PRSUs have been earned subsequent to the first anniversary of the grant date as of December 31, 2016 . On June 29, 2016, the Company granted 3,034,329 PRSUs under the Incentive Plan to its executive officers and other members of the Company’s senior leadership team as of that date (i.e., the “2016 LTIP”). The PRSUs granted are contingent upon the Company’s performance with respect to certain predetermined Total Cumulative Revenue targets over the 33 -month period commencing April 1, 2016 and concluding December 31, 2018, subject to the Company’s achievement of a predetermined cumulative Adjusted EBITDA threshold over the same time period. Of the 3,034,329 PRSUs granted, 2,748,073 PRSUs remained outstanding as of December 31, 2016 due to forfeitures during the year, representing the number of shares to be issued at the 100% target achievement level for this award. The number of shares ultimately issued could be 0% or range from 75% (threshold achievement level) to 200% (maximum achievement level) of the number of PRSUs outstanding, based on the Company’s performance in relation to the performance conditions, and linear interpolation will be applied should Total Cumulative Revenue fall between the threshold and maximum achievement levels. Any PRSUs earned under the 2016 LTIP will vest in full on May 31, 2019, subject to continued employment as of that date. The Company is recognizing stock-based compensation expense for these awards over the vesting period based on the projected probability of achievement of the aforementioned performance conditions as of the end of each reporting period during the performance period and may periodically adjust the recognition of such expense, as necessary, in response to any changes in the Company’s forecasts with respect to the performance conditions. For the year ended December 31, 2016 , the Company did not recognize any stock-based compensation expense related to the 2016 LTIP based on the Company’s determination that achievement of the performance conditions was not probable as of that date. Once vested, shares will generally either be issued net of the applicable tax withholding requirements to be paid by the Company on behalf of employees, or a portion of the shares issued will subsequently be sold by employees to satisfy the tax obligations created by the vesting of PRSUs. The Company recognized stock-based compensation expense of $1,685 , $581 and $0 in the consolidated statements of operations related to PRSUs in 2016 , 2015 and 2014 , respectively. As of December 31, 2016 , total unrecognized stock-based compensation expense related to PRSUs was $552 , which will be recognized over a remaining weighted-average life of 0.93 years . Employee Stock Purchase Plan The Company implemented an Employee Stock Purchase Plan (“ESPP”) during 2016. The ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations, and provides for six -month offering periods, commencing in May and November of each year. At the end of each offering period, participating employees are able to purchase shares of common stock at 90% of the Company’s stock price at market close on the first trading day of the offering period or the last trading day of the offering period, whichever is lower. In April 2016, the Company registered 1,755,500 shares of common stock under the ESPP. During 2016 , there were 68,723 shares purchased by employees under the ESPP at a purchase price of $6.93 per share. The Company recognized stock-based compensation expense of $189 in the consolidated statement of operations related to the ESPP in 2016 . As of December 31, 2016 , 1,686,777 shares of common stock remained available for purchase under the ESPP.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company accounts for income taxes in accordance with authoritative guidance, which requires the use of the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon the difference between the consolidated financial statement amounts and the tax basis of assets and liabilities and are measured using the enacted tax rate expected to apply to taxable income in the years in which the differences are expected to be reversed. As management believes it is more likely than not that the Company will not realize the full amount of its net deferred tax assets, the Company recorded a valuation allowance for the deferred tax assets as of December 31, 2016 , 2015 and 2014 . The provision for income taxes for the years ended December 31, 2016 , 2015 and 2014 consisted of the following components: 2016 2015 2014 Current: U.S. federal $ — $ — $ — State 21 27 40 Total current 21 27 40 Deferred: U.S. federal $ 17 $ 17 $ 10 State 5 — 1 Total deferred 22 17 11 Provision for income taxes $ 43 $ 44 $ 51 The reconciliation of income tax expense computed at the U.S. federal statutory rate to the Company’s effective tax rate for the years ended December 31, 2016 , 2015 and 2014 is as follows: 2016 2015 2014 U.S. federal income tax rate 34.0 % 34.0 % 34.0 % State income taxes, net of federal benefit 9.1 % (1.3 )% (0.5 )% Valuation allowance (41.0 )% (29.7 )% (20.1 )% Stock-based compensation 6.3 % 15.6 % (9.4 )% Research and development credits 1.0 % (16.4 )% — % Internal Revenue Code Section 162(m) (8.3 )% — % — % Other (1.7 )% (1.8 )% (4.4 )% Effective income tax rate (0.6 )% 0.4 % (0.4 )% Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2016 and 2015 are as follows: 2016 2015 Deferred tax assets: Deferred revenue $ 27,239 $ 34,177 Intangibles - other 9,210 10,088 Net operating loss carryforwards 62,033 50,885 Stock-based compensation 8,529 5,301 Research and development credits 2,864 2,556 Other 5,341 3,756 Total deferred tax assets 115,216 106,763 Valuation allowance (89,854 ) (84,035 ) Total net deferred tax assets 25,362 22,728 Deferred tax liabilities: Prepaid expenses $ (4,022 ) $ (3,853 ) Property, equipment and software (21,340 ) (18,875 ) Goodwill (220 ) (198 ) Total net deferred tax liabilities (25,582 ) (22,926 ) Total net deferred tax liability $ (220 ) $ (198 ) As of December 31, 2016 , the Company had net operating loss carryforwards for federal and state income tax purposes of approximately $159,329 and $210,891 , respectively. The net operating loss carryforwards will expire in future years, primarily beginning in 2027 . The net operating losses may be subject to annual limitations of use under Internal Revenue Code Section 382. The Company files income tax returns in the U.S. federal jurisdiction and in various state jurisdictions. Income tax returns for the short year ended December 31, 2010 to present are open for examination in the federal jurisdiction and in significant state jurisdictions. A valuation allowance is provided when it is more likely than not that some portion of the deferred tax asset will not be realized. The Company does not benefit from its deferred tax assets based on the deferred tax liabilities related to goodwill that are not expected to reverse during the carryforward period. As this deferred tax liability would not reverse until some future indefinite period when the intangibles are either sold or impaired, any resulting temporary differences cannot be considered a source of future taxable income to support realization of the deferred tax assets. At December 31, 2016 and 2015 , the Company did not have any material unrecognized income tax benefits recorded in its consolidated balance sheets.

The first quarter of 2016 included a $3,500 charge to general and administrative expense related to a contingent legal liability recorded in connection with the Moore litigation and related cases. This contingent liability was subsequently reduced during the fourth quarter of 2016, yielding a benefit of $671 to fourth quarter general and administrative expense. In connection with the Company’s early adoption of ASU 2016-09 during the third quarter of 2016, the Company was required to record a modified retrospective transition adjustment at the time of adoption to reflect an increase in stock-based compensation expense for 2016 related to the Company’s forfeitures election under this new standard. Although this adjustment was recorded during the third quarter, given the modified retrospective nature of the adjustment, the Company was precluded from presenting the full amount of the adjustment in the consolidated financial statements for the quarter ended September 30, 2016 and was instead required to update amounts previously reported, yielding retrospective increases to general and administrative expense of $638 and $140 for the quarters ended March 31, 2016 and June 30, 2016, respectively. As a result, the operating income (loss), net income (loss) and corresponding per share figures presented in the table above for the first and second quarters of 2016 differ from amounts previously reported. For the third quarter of 2016, the Company’s basic and diluted weighted-average number of common shares outstanding was 58,883,623 , and basic and diluted net loss per common share was $(0.29) , as reflected in the table above. These amounts were previously incorrectly reported as 59,495,592 and $(0.28) , respectively. The Company does not believe this correction is material to these consolidated financial statements or any previously issued consolidated financial statements. The second quarter of 2015 included a $686 charge to general and administrative expense for the recognition of a non-cash long-lived asset impairment related to the Company’s decision not to pursue its Indianapolis campus expansion plan. The fourth quarter of 2015 included an $892 charge to product and technology expense for the recognition of a non-cash long-lived asset impairment related to the abandonment of certain software assets.

Description of Business, Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Nature of Operations	Basis of Presentation The consolidated financial statements were prepared in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) and reflect all adjustments of a normal recurring nature considered, in the opinion of management, necessary to fairly report the results for the periods presented.
Operating Segments	Operating Segments Operating segments are defined as components of an enterprise engaging in business activities for which discrete financial information is available and regularly reviewed by the chief operating decision maker in deciding how to allocate resources and in assessing performance. The Company manages its business on the basis of one operating segment.
Principles of Consolidation	Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions are eliminated in consolidation.
Estimates	Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the consolidated financial statements and accompanying notes as well as the disclosure of contingent assets and liabilities and reported revenue and expenses. Actual results could differ from those estimates.
Reclassification of Prior Year Presentation	Reclassification of Prior Year Presentation Certain prior year amounts were reclassified for consistency with the current period presentation, including the marketing compensation and personnel-related costs and general marketing operating expenditures that were moved from general and administrative expense and selling expense to marketing expense within the consolidated statements of operations. These reclassifications did not impact net income (loss) previously reported.
Revenue Recognition and Deferred Revenue	Revenue Recognition The Company recognizes revenue when all of the following conditions are met: there is persuasive evidence of an arrangement, the service has been provided to the customer, the collection of fees is reasonably assured and the amount of fees to be paid by the customer is fixed or determinable.
Revenue Recognition, Subscription Revenue [Policy Text Block]	Membership Revenue. Revenue from the sale of membership subscriptions is generally recognized ratably over the term of the associated subscription.
Service Provider Revenue	Service Provider Revenue. Revenue from the sale of website, mobile and call center advertising is recognized ratably over the time period the advertisements run. Revenue from the sale of advertising in the Company’s Angie’s List Magazine publication is recognized in the period in which the publication is published and distributed. Revenue from e-commerce vouchers is recognized on a net basis when the voucher is delivered to the purchaser. While the Company is not the merchant of record with respect to its customers for these transactions, it does offer customers refunds in certain circumstances. Accordingly, revenue from e-commerce transactions is recorded net of a reserve for estimated refunds.
Deferred Revenue	Deferred Revenue. Deferred revenue includes the unamortized portion of revenue associated with membership and service provider fees for which the Company received payment in advance of services or advertising to be provided. Deferred revenue is recognized as revenue when the related services or advertising are actually provided.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company maintains its cash in bank deposit accounts and money market funds with contractual maturities of three months or less, which, at times, may exceed federally insured limits. The Company also classifies as cash and cash equivalents any investments in certificates of deposit, U.S. Treasury securities or corporate bonds with contractual maturities of three months or less, which also, at times, may exceed federally insured limits. To date, the carrying values of the Company’s cash and cash equivalents approximate their fair values, and there have been no material losses in these accounts.
Short-Term Investments	Short-Term Investments Short-term investments consist of certificates of deposit, U.S. Treasury securities or corporate bonds with maturities of more than 90 days but less than one year, all of which are designated as held-to-maturity investments and recorded at amortized cost, adjusted, as applicable, for amortization of premiums to maturity computed under the effective interest method, in the consolidated balance sheets. Amortization and interest income from held-to-maturity investments are included in interest expense, net, in the consolidated statements of operations. The Company’s objective with respect to these investments is to earn a higher rate of return on funds that are otherwise not anticipated to be required to meet liquidity needs in the near term while maintaining a low level of investment risk with the positive intent and ability to hold these investments to maturity. The Company reviews its investment portfolio for other-than-temporary impairment whenever events or changes in circumstances indicate the carrying amount of the investment may be impaired, considering such factors as the duration, severity and reason for the decline in value as well as the potential recovery period. As of December 31, 2016 and 2015 , the Company held $16,541 and $23,976 , respectively, in short-term investments with no material unrealized gains or losses in these accounts in either year then ended.
Accounts Receivable	Accounts Receivable Accounts receivable is stated at the amount billed to service providers, less an estimated allowance for doubtful accounts. The Company performs ongoing credit evaluations and generally requires no collateral from service providers. Management reviews individual accounts as they become past due to determine collectability. The Company’s allowance for doubtful accounts balance is adjusted periodically based on management’s consideration of past due accounts. Individual accounts are charged against the allowance when all reasonable collection efforts are exhausted.
Property, Equipment and Software	Property, Equipment and Software Assets recorded as property, equipment and software are stated at cost and depreciated over their respective estimated useful lives. The Company also capitalizes certain costs related to website and software acquisition and development for internal use, including internal labor costs incurred during development. Construction in progress is comprised of costs incurred related to the construction or development of property, equipment and software that is not ready for its intended use and therefore not yet placed in service. The Company’s estimated useful lives for property, equipment and software generally range from 3 to 25 years . Depreciation/amortization is computed using the straight-line method. Repairs and routine maintenance are charged to expense as incurred. In accordance with authoritative guidance, the Company begins to capitalize website and software development costs for internal use when planning and design efforts are successfully completed and development is ready to commence. Costs incurred during planning and design, together with costs incurred for training and maintenance, are expensed as incurred and recorded in product and technology expense within the consolidated statements of operations. The Company places capitalized website and software development assets into service and commences depreciation/amortization when the applicable project or asset is substantially complete and ready for its intended use. Once placed into service, the Company capitalizes qualifying costs of specified upgrades or enhancements to capitalized website and software development assets when the upgrade or enhancement will result in new or additional functionality. The Company capitalizes internal labor costs, including compensation, benefits and payroll taxes, incurred for certain capitalized website and software development projects related to the Company’s technology platform. The Company’s policy with respect to capitalized internal labor stipulates that labor costs for employees working on eligible internal use capital projects are capitalized as part of the historical cost of the project when the impact, as compared to expensing such labor costs, is material. The Company also capitalized a portion of the interest on funds borrowed in relation to the development of the Company’s technology platform. The Company’s policy with respect to capitalized interest specifies that interest costs on eligible long-term internal use capital projects are capitalized as part of the historical cost of the project when the impact, as compared to expensing such interest costs, is material.
Goodwill	Goodwill Goodwill is not amortized and is instead reviewed for impairment, at a minimum, on an annual basis as of December 31, or more frequently should an event or circumstance occur that indicates the carrying amount of goodwill may be impaired. If goodwill is considered to be impaired, the impairment to be recognized equals the amount by which the carrying value of the goodwill exceeds its fair market value. To date, no impairment of goodwill has been identified or recognized.
Data Acquisition Costs	Data Acquisition Costs Data acquisition costs consist of external costs related to acquiring consumer reports on service providers. These reports are used by the Company to provide its members with feedback on service providers. Amortization is computed using the straight-line method over the period during which the information is expected to benefit the Company’s members, which is estimated to be three years. The capitalized costs are included in intangible assets in the consolidated balance sheets, and the amortized expense is reflected within operations and support expense in the consolidated statements of operations.
Long-Lived Assets	Long-Lived Assets Long-lived assets, including property, equipment and software and amortizable intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability is measured by comparison of the carrying amount to future net undiscounted cash flows expected to be generated by the related asset. If such assets are considered to be impaired, the impairment to be recognized is measured as the amount by which the carrying amount exceeds the fair market value of the assets. Long-lived asset impairment charges were recorded during the second and fourth quarters of 2015 as discussed in further detail in Note 5, “Property, Equipment and Software,” of these Notes to Consolidated Financial Statements.
Deferred Financing Fees	Deferred Financing Fees As a result of the Company’s entry into a new financing agreement in September 2014, the Company incurred financing costs that were capitalized as a deferred financing fee asset. As further discussed below, upon adoption of the guidance set forth under Accounting Standards Update No. 2015-03, effective January 1, 2016, the Company reclassified the deferred financing fees previously recorded in other noncurrent assets to net long-term debt in the consolidated balance sheets. The deferred financing fees contra liability is offsetting the gross term loan balance and is being amortized to interest expense on a straight-line basis over the term of the financing agreement. The Company’s long-term debt balance is reported net of the remaining unamortized deferred financing fees within the consolidated balance sheets. In connection with the extinguishment of the Company’s previous loan and security agreement during the course of the aforementioned financing transaction, the Company expensed the remaining unamortized portion of the capitalized deferred financing fees associated with the previous loan and security agreement in 2014, and the related amount was included in the loss on debt extinguishment within the consolidated statement of operations for the year ended December 31, 2014.
Fees Paid to Lender	Fees Paid to Lender The Company incurred financing costs in the form of fees paid directly to the lender during the completion of its September 2014 debt financing transaction and in connection with the execution of the second amendment to the financing agreement in November 2016. In accordance with the applicable authoritative guidance, these fees were recorded as a contra liability, offsetting the gross term loan balance. The fees paid to lender contra liability is being amortized to interest expense on a straight-line basis over the term of the financing agreement. The Company’s long-term debt balance is reported net of the remaining unamortized fees paid to the lender within the consolidated balance sheets.
Leases	Leases The Company leases office space pursuant to long-term non-cancellable operating leases expiring through 2021. Rent expense is recognized on a straight-line basis over the expected lease term. Certain of the Company’s leases contain provisions for tenant improvement allowances, which are recorded as a deferred rent liability and amortized over the term of the associated lease as an offset to rent expense each period. Leasehold improvements are capitalized to property, equipment and software and depreciated on a straight-line basis over the corresponding estimated useful lives.
Sales Commissions	Sales Commissions Commissions expense from the sale of service provider advertisements is recognized ratably over the term of the associated advertisement. The Company defers the recognition of commission expense until such time as the revenue related to the contract for which the commission was paid is recognized. Deferred commissions for each contract are amortized to expense in a manner consistent with how revenue is recognized for each contract, resulting in straight-line recognition of expense over the contractual term. Unamortized commission expense of $8,869 and $8,573 as of December 31, 2016 and 2015 , respectively, is included in prepaid expenses and other current assets in the accompanying consolidated balance sheets.
Marketing Expense	Marketing Expense Marketing expense consists of national television, radio and print advertising as well as online digital advertising. The Company generally expenses advertising costs as incurred. The Company recorded advertising spend of $46,056 , $71,534 and $87,386 as a component of marketing expense in the consolidated statements of operations for the years ended December 31, 2016 , 2015 and 2014 , respectively.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation expense using the fair value measurement and recognition provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 718, Stock Compensation . For awards of stock options, restricted stock units (“RSUs”) and certain performance awards of restricted stock units (“PRSUs”), the Company recognizes stock-based compensation expense over the requisite service period in an amount equal to the fair market value on the grant date of the respective award. For PRSUs granted subject to the Company’s performance in relation to predetermined performance conditions, the Company recognizes stock-based compensation expense over the vesting period based on the projected probability of achievement of the performance conditions as of the end of each reporting period during the performance period and may periodically adjust the recognition of such expense, as necessary, in response to any changes in the Company’s forecasts with respect to the performance conditions. The fair value of stock options is estimated at the date of grant using the Black-Scholes option-pricing model utilizing the historical weighted-average assumptions outlined in Note 11, “Stock-Based Compensation,” of these Notes to Consolidated Financial Statements. The fair value of RSUs, as well as PRSUs granted subject to the Company’s performance in relation to predetermined performance conditions, is based on the fair market value of the underlying stock on the date of grant. The fair value of PRSUs contingent upon the performance of the Company’s stock price in relation to certain predetermined thresholds is estimated as of the date of grant using a Monte Carlo option-pricing simulation model. Effective January 1, 2016, the Company began utilizing its own historical data for the volatility input to the calculation of the estimated fair value of stock option awards as there is now sufficient historical volatility data available to do so. Additionally, in connection with the adoption of ASU 2016-09 during the third quarter of 2016, the Company elected to commence accounting for forfeitures of share-based payment awards as they occur instead of recognizing stock-based compensation expense net of estimated forfeitures.
Commitments and Contingencies, Policy [Policy Text Block]	Loss Contingencies The Company is involved in various lawsuits, claims, investigations and other legal and regulatory proceedings, both as a plaintiff and as a defendant, related to its business and operations. The Company records a liability when it is both probable a loss has been incurred and the amount can be reasonably estimated. If the Company determines a loss is possible and a range of loss can be reasonably estimated, the Company discloses the range of the possible loss in these Notes to Consolidated Financial Statements. Significant judgment is required to determine the probability or possibility, as well as the estimated amount, as applicable, of a loss contingency. On at least a quarterly basis, as necessary, the Company reviews and evaluates developments with respect to legal matters that could impact the amount of an associated liability previously accrued, as well as the related ranges of possible losses disclosed, and makes adjustments and changes as appropriate.
Loss On Debt Extinguishment	Loss on Debt Extinguishment The penalties, additional interest and other fees and expenses incurred in connection with the prepayment of the Company’s previous debt facility in September 2014, together with the amounts related to the write-off of the previous deferred financing fees and recognition of the remaining interest expense under the previous debt facility, were included within the loss on debt extinguishment contained in the consolidated statement of operations for the year ended December 31, 2014.
Sales and Use Tax	Sales and Use Tax Currently, the Company does not separately collect sales and use taxes from its members. Instead, the Company reports and, if applicable, pays sales and use taxes on behalf of its members in certain jurisdictions and records an accrual for sales and use tax based on probable liability within other applicable jurisdictions.
Income Taxes	Income Taxes The Company is subject to corporate federal and state income taxes at prevailing corporate rates and accounts for income taxes and the related accounts using the asset and liability method in accordance with ASC 740, Income Taxes . Under this method, the Company accrues income taxes payable or refundable and recognizes deferred tax assets and liabilities based on differences between the book and tax basis of assets and liabilities. The Company measures deferred tax assets and liabilities using enacted rates in effect for the years in which the differences are expected to reverse and recognizes the effect of a change in enacted rates in the period of enactment. After determining the total amount of deferred tax assets, the Company determines whether it is more likely than not that some portion of the deferred tax assets will not be realized. If the Company determines a deferred tax asset is not likely to be realized, a valuation allowance is established against that asset to record it at its expected realizable value. The Company periodically reviews deferred tax assets for recoverability based on historical taxable income, projected future taxable income and the expected timing of reversals of existing temporary differences. Should there be a change in the ability to recover deferred tax assets, the tax provision would be adjusted in the period in which the assessment changed. The Company establishes assets and liabilities for uncertain positions taken or expected to be taken in income tax returns using a more-likely-than-not recognition threshold. The Company includes in income tax expense any interest and penalties related to uncertain tax positions.
Recent Accounting Pronouncements	Recent Accounting Pronouncements - Adopted As of January 1, 2016, the Company adopted FASB Accounting Standards Update No. 2015-03: Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs , which set forth a requirement that debt issuance costs related to a recognized debt liability be presented on the balance sheet as a direct deduction from the carrying amount of that liability, resulting in the Company reclassifying the deferred financing fees previously recorded in other noncurrent assets, amounting to $1,462 as of December 31, 2015, to net long-term debt in the consolidated balance sheets. As of August 1, 2016, the Company adopted FASB Accounting Standards Update No. 2016-09: Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which simplified several aspects of the accounting guidance for employee share-based payment transactions, including accounting for income taxes, forfeitures and statutory tax withholding requirements, as well as classification in the statement of cash flows. The guidance requires companies to record excess tax benefits and tax deficiencies as income tax benefit or expense in the statement of operations when share-based payment awards vest or are settled. Upon adoption, the Company’s previously unrecognized excess tax benefits were recorded as a deferred tax asset, which was fully offset by a valuation allowance. Without the valuation allowance, the Company’s deferred tax asset would have increased by $2,406 . Additionally, under the new guidance, the Company elected to begin accounting for forfeitures of share-based payment awards as they occur in lieu of the previous practice of estimating the number of awards expected to be forfeited and adjusting the estimate when it was no longer probable that the corresponding service condition would be fulfilled. As ASU 2016-09 was adopted as of an interim date, the Company recorded a modified retrospective transition adjustment as of the beginning of 2016 during the third quarter to reflect an increase in stock-based compensation expense of $804 related to the forfeitures election. No changes in presentation or classification in the statement of cash flows were required in connection with the adoption of ASU 2016-09, and the Company is now allowing share withholding for taxes upon the vesting of RSUs and PRSUs in excess of the minimum statutory tax withholding requirements, as permitted by ASU 2016-09. Recent Accounting Pronouncements - Not Yet Adopted In January 2017, the FASB issued Accounting Standards Update No. 2017-04: Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”). The amendments in this update simplify the accounting for goodwill impairments by eliminating step 2 from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss will be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to the reporting unit. ASU 2017-04 will be effective for the Company in fiscal year 2020, but early adoption is permitted. The Company is currently evaluating the impact of this update on the consolidated financial statements. In August 2016, the FASB issued Accounting Standards Update No. 2016-15: Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The amendments in this update add to or clarify existing U.S. GAAP guidance on the classification of certain cash receipts and payments in the statement of cash flows. ASU 2016-15 will be effective for the Company in fiscal year 2018, but early adoption is permitted. The guidance set forth in this update must be applied retrospectively to all periods presented but may be applied prospectively if retrospective application would be impracticable. The Company is currently evaluating the impact of this update on the consolidated financial statements. In June 2016, the FASB issued Accounting Standards Update No. 2016-13: Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). The amendments in this update add to U.S. GAAP a current expected credit loss impairment model that is based on expected losses rather than incurred losses, requiring consideration of a broader range of reasonable and supportable information to inform credit loss estimates. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses, which the FASB believes will result in more timely recognition of such losses. ASU 2016-13 is also intended to reduce the complexity of U.S. GAAP by decreasing the number of credit impairment models that entities use to account for debt instruments. ASU 2016-13 will be effective for the Company in fiscal year 2020, but early adoption is permitted beginning in 2019. The Company is currently evaluating the impact of this update on the consolidated financial statements. In February 2016, the FASB issued Accounting Standards Update No. 2016-02: Leases (Topic 842) (“ASU 2016-02”). The amendments in this update require lessees, among other things, to recognize lease assets and lease liabilities on the balance sheet for those leases classified as operating leases under previous authoritative guidance. This update also introduces new disclosure requirements for leasing arrangements. ASU 2016-02 will be effective for the Company in fiscal year 2019, but early adoption is permitted. The Company is currently evaluating the impact of this update on the consolidated financial statements. In January 2016, the FASB issued Accounting Standards Update No. 2016-01: Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). The amendments in this update address certain aspects of recognition, measurement, presentation and disclosure of financial instruments. In particular, the amendments in this update supersede, for public business entities, the requirement to disclose the methods and significant assumptions used in calculating the fair value of financial instruments required to be disclosed for financial instruments measured at amortized cost on the balance sheet. ASU 2016-01 will be effective for the Company in fiscal year 2018, but early adoption is permitted. The Company does not believe that the adoption of the guidance set forth in this update will have a material impact on the consolidated financial statements. In May 2014, the FASB issued Accounting Standards Update No. 2014-09: Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). This update outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that “an entity recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.” This update also requires significantly expanded disclosures related to revenue recognition. In March 2016, the FASB issued Accounting Standards Update No. 2016-08: Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”) , amending the principal-versus-agent implementation guidance set forth in ASU 2014-09. Among other things, ASU 2016-08 clarifies that an entity should evaluate whether it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued Accounting Standards Update No. 2016-10: Identifying Performance Obligations and Licensing (“ASU 2016-10”), which amends certain aspects of the guidance set forth in the FASB’s new revenue standard related to identifying performance obligations and licensing implementation. In May 2016, the FASB issued Accounting Standards Update No. 2016-12: Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”), amending certain aspects of ASU 2014-09 to address implementation issues identified by the FASB’s transition resource group and clarify the new revenue standard’s core revenue recognition principles. In December 2016, the FASB issued Accounting Standards Update No. 2016-20: Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”), which clarified or corrected unintended application of certain aspects of the guidance set forth under ASU 2014-09. ASU 2014-09 will be effective for the Company in fiscal year 2018 following the issuance of Accounting Standards Update No. 2015-14: Deferral of the Effective Date in August 2015, which deferred the effective date of ASU 2014-09 by one year. The Company currently anticipates adopting the new revenue recognition standard effective January 1, 2018 utilizing the modified retrospective method of adoption. Accordingly, upon adoption, the Company currently anticipates recognizing the cumulative effect of adopting this guidance as an adjustment to the opening balance of the accumulated deficit within the consolidated balance sheet for the period of adoption, and prior periods will not be retrospectively adjusted. The Company identified the following revenue streams that will be further evaluated in detail based on the criteria established under the new revenue standard: membership revenue, service provider advertising revenue and service provider e-commerce revenue. The Company is still in the process of evaluating the impact of these updates on the consolidated financial statements and related disclosures.
