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 consumers can research, shop for and purchase local services for critical needs, such as home, health and automotive services, as well as rate and review the providers of these services. Ratings and reviews, which are available only to the Company’s members, assist members in identifying and hiring a highly-rated provider for their local service needs. Membership subscriptions are sold on a monthly, annual and multi-year basis. The Company also sells advertising in its monthly publication, on its website and mobile applications and through its call center to service providers that meet certain eligibility criteria. In addition, the Company’s e-commerce marketplace offerings provide consumers with the opportunity to purchase services directly through the Company's marketplace from highly-rated service providers. 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”). 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 were 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. The consolidated financial statements reflect all adjustments of a normal recurring nature considered, in the opinion of management, necessary to fairly report the results for the periods presented. Reclassification of Prior Year Presentation Certain prior year amounts were reclassified for consistency with the current period presentation. These reclassifications did not materially impact the consolidated financial statements. 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 recognized ratably over the term of the associated subscription. Prior to 2014, the Company also generally received a one-time, nonrefundable enrollment fee at the time a member joined. Enrollment fees were deferred and are being recognized as revenue ratably over an estimated average membership life of 80 months for annual or multi-year members and 13 months for monthly members, based on historical membership experience. The Company discontinued charging one-time, nonrefundable enrollment fees in 2014. 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 and 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 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 that 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, 2015 and 2014 , the Company held $23,976 and $24,268 , 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, 2015 , 2014 and 2013 were as follows: Year Ended December 31, 2015 2014 2013 Beginning balance $ 1,651 $ 1,107 $ 922 Additions, net of recoveries 5,746 5,028 3,773 Deductions (5,739 ) (4,484 ) (3,588 ) Ending balance $ 1,658 $ 1,651 $ 1,107 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 the associated interest and internal labor costs incurred during development. Construction in progress is 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 range from 3 to 25 years . Depreciation 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 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 additional functionality. The Company is capitalizing a portion of the interest on funds borrowed in relation to the capitalized website and software development costs incurred for the ongoing development around the Company's website and technology platform. The Company's policy with respect to capitalized interest specifies that interest costs on 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. For the year ended December 31, 2015 , total interest costs incurred amounted to $5,131 , of which $3,570 was capitalized as construction in progress for website and software development costs. For the year ended December 31, 2014 , total interest costs incurred amounted to $2,613 , of which $1,410 was capitalized as construction in progress for website and software development costs. No interest costs were capitalized for the year ended December 31, 2013 . The Company is also capitalizing internal labor costs, including compensation, benefits and payroll taxes, incurred for the ongoing capitalized website and software development project related to the Company's website and technology platform. The Company's policy with respect to capitalized internal labor stipulates that labor costs for employees working on 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. As of December 31, 2015 and 2014 , internal labor costs amounting to $11,107 and $4,410 , respectively, were capitalized as construction in progress for website and software development costs. 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 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 that 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 by 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 well as the fourth quarter of 2014 as discussed in further detail in Note 5, “Property, Equipment and Software,” of these Notes to Consolidated Financial Statements. No other adjustments to the respective carrying values of the Company's long-lived assets have been recorded to date. 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 and are being amortized into interest expense over the term of the financing agreement. 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. 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 related debt. 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 noncancellable 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 $8,573 and $11,378 as of December 31, 2015 and 2014 , 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. Stock-Based Compensation The Company accounts for stock-based compensation using the fair value 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 performance awards of restricted stock units (“PRSUs”), the Company recognizes stock-based compensation expense in an amount equal to the fair market value on the grant date of the respective award. The Company recognizes this expense, net of estimated forfeitures, over the requisite service period. The Company estimates the forfeiture rates utilized based on historical forfeitures of equity awards and adjusts the rates to reflect changes in facts and circumstances, if any, as deemed necessary. The Company's estimated forfeiture rates are revised if actual forfeitures differ from initial estimates. The fair value of stock options granted 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 granted is based on the fair market value of the underlying stock on the date of grant, while the the fair value of PRSUs granted is estimated as of the date of grant using a Monte Carlo option-pricing simulation model. Loss Contingencies The Company is involved in various lawsuits, claims, investigations and proceedings. The Company records a liability when it is both probable that a loss has been incurred and the amount can be reasonably estimated. If the Company determines that 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 Sales and use tax expenses are included within operations and support expense in the consolidated statements of operations. The Company does not separately collect sales and use taxes from its members. Instead, the Company records an accrual for sales and use tax based on probable liability within applicable jurisdictions. 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 that 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 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 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 application 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 application 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 November 2015, the FASB issued Accounting Standards Update No. 2015-17: Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). The amendments in this update require that deferred tax assets and liabilities be presented as noncurrent in a classified balance sheet, simplifying the previous guidance, which required entities to separately present deferred tax assets and liabilities as current and noncurrent in a classified balance sheet. Under the guidance set forth in this update, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets as those allowances will also be classified as noncurrent. ASU 2015-17, which may be applied on either a retrospective or prospective basis at the option of the Company, will be effective for the Company in fiscal year 2017, but early adoption is allowed. The Company adopted ASU 2015-17 for the year ended December 31, 2015 and elected to retrospectively apply, noting no material impact to the consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update No. 2015-05: Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”). The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the update specifies that the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. The update further specifies that the customer should account for a cloud computing arrangement as a service contract if the arrangement does not include a software license. ASU 2015-05 will be effective for the Company in fiscal year 2016. 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 April 2015, the FASB issued Accounting Standards Update No. 2015-03: Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). This update sets forth a requirement that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this update. ASU 2015-03 will be effective for the Company in fiscal year 2016. Retrospective application of the guidance set forth in this update is required, and as such, once effective, will result in a reclassification of the deferred financing fees currently recorded as a noncurrent asset within the consolidated balance sheet to a direct deduction from the carrying amount of long-term debt within noncurrent liabilities. In August 2014, the FASB issued Accounting Standards Update No. 2014-15: Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (“ASU 2014-15”). The update sets forth a requirement for management to evaluate whether there are conditions and events that raise substantial doubt about an entity's ability to continue as a going concern, a responsibility that did not previously exist in U.S. GAAP. The amendments included in this update require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term substantial doubt, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 will be effective for the Company in fiscal year 2016. 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”). The 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.” The update also requires significantly expanded disclosures related to revenue recognition. ASU 2014-09 will be effective for the Company in fiscal year 2018 following the issuance of ASU 2015-14 in August 2015, which deferred the effective date of ASU 2014-09 by one year. The Company is currently evaluating the future impact and method of adoption of this update with respect to the consolidated financial statements.

Fair Value Measurements

Fair Value Measurements	12 Months Ended
	Dec. 31, 2015
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 , 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, which possess maturities of 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 of the Company’s cash equivalents and investments during 2015 or 2014 , and there were no material unrealized gains or losses in these accounts as of December 31, 2015 or 2014 . 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, 2015 and 2014 : 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 $ — Fair Value Measurement at December 31, 2014 Using Carrying Value at December 31, 2014 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 $ 365 $ 365 $ — $ — Certificates of deposit 240 — 240 — Investments: Certificates of deposit 21,235 — 21,211 — Corporate bonds 3,033 — 3,028 — Total assets $ 24,873 $ 365 $ 24,479 $ — The Company did not recognize any other-than-temporary impairment losses for the years ended December 31, 2015 , 2014 , or 2013 . 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, 2015 and 2014 . 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,” 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, such as the current and prior year non-cash long-lived asset impairment charges (see Note 5 for additional information), 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.

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 that 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. Clark v. Oesterle, et al., C.A. No. 10255. On October 17, 2014, a derivative complaint was filed in the Court of Chancery of the State of Delaware, naming members of the Company’s Board of Directors and various current and former officers as individual defendants. The complaint alleges that the individual defendants breached their fiduciary duties by making misleading representations regarding, among other things, the Company’s business prospects. The complaint also alleges that certain individual defendants breached their fiduciary duties by selling shares of Angie’s List common stock between February 2013 and October 2013. The Court issued an order staying the action pending a ruling on the motion to dismiss in the Putative Securities Class Action Litigation described above. On October 12, 2015, the plaintiff filed an amended complaint alleging that the individual defendants breached their fiduciary duties by engaging in business practices that were contrary to the Company's representations. The plaintiffs filed a voluntary motion to dismiss on February 2, 2016, and the Court ordered dismissal on February 2, 2016. Moore 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 alleges claims of breaches of contract and 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 will impact the service provider letter grade ratings, the content and availability of reviews about the provider, and the provider's placement 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 breach of covenant of good faith and unjust enrichment claims were dismissed from the action based on the face of the plaintiff's complaint. Pursuant to the Court’s recently amended scheduling order, the parties must complete discovery by April 14, 2016 and file any summary judgment motions by April 25, 2016. The parties have exchanged extensive written and document discovery and have conducted depositions. The parties are also exploring the possibility of resolving the matter. Certain other cases, with similar allegations and filed by some of the same plaintiffs’ counsel, were also filed in two other jurisdictions, California and New Jersey. However, the Company has not been served with the summons and complaint in the California matter, and no action is currently necessary as a result. Glick v. Angie's List, Inc., 2:16-cv-00546 . On February 1, 2016, Gary Glick, an Angie's List member, filed a putative class action lawsuit in the United States District Court for the District of New Jersey. The plaintiff alleges that the Company deceives its consumers by representing that service providers “can't pay” or “don't pay” to be on Angie's List, while concealing that service providers pay advertising fees to influence their search result ranking, and further asserts other claims substantially similar to those alleged in the Moore litigation. The plaintiff's complaint includes claims for breach of contract and for a violation of the New Jersey Consumer Fraud Act. Glick served the summons and complaint on February 23, 2016, and the parties have submitted a joint stipulation to extend the response deadline by 75 days as the outcome of the Moore litigation could moot any further proceedings in the Glick action. The Court has yet to rule on the stipulation.

Stock Options Stock options are awarded with an exercise price equal to the market 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. A summary of stock option activity under the Incentive Plan as of December 31, 2015 and 2014 and changes during the periods then ended are as follows: Number of Shares Weighted-Average Weighted-Average Aggregate (in years) (in thousands) Outstanding at December 31, 2013 3,310,764 $ 14.67 8.63 $ 9,717 Granted 3,239,740 10.89 Exercised (60,632 ) 8.26 Forfeited/Cancelled (1,050,975 ) 11.54 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 Number of Shares Weighted-Average Weighted-Average Aggregate (in years) (in thousands) Vested and Exercisable at December 31, 2014 1,248,711 $ 12.97 7.23 $ — Unvested at December 31, 2014 4,190,186 13.13 9.04 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 The aggregate intrinsic value as shown in the tables above is calculated as 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, 2015 , 2014 and 2013 : Year of Grant Risk-Free Dividend Expected Volatility (in years) 2013 1.02% 0% 4.90 57.0% 2014 1.67% 0% 5.00 53.0% 2015 1.48% 0% 5.00 53.1% 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. As the Company's common stock was never publicly traded prior to November 17, 2011, and the Company does not believe its historical volatility is representative of the Company's future volatility, 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. 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 expected term represents the period of time the stock options are expected to be outstanding based on historical experience. The weighted-average grant date fair value of stock options granted during 2015 , 2014 and 2013 was $2.95 , $5.12 and $9.38 per share, respectively. The total intrinsic value of stock options exercised during 2015 , 2014 and 2013 was $133 , $456 and $7,376 , respectively. The Company recognized stock-based compensation expense of $7,321 , $7,889 and $4,064 in the consolidated statements of operations related to stock options in 2015 , 2014 and 2013 , respectively. As of December 31, 2015 , total unrecognized stock-based compensation expense related to unvested stock options, reflecting an estimated forfeiture rate, was $12,111 , which will be recognized over the remaining weighted-average life of the awards, 2.44 years. Restricted Stock Units 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. A summary of RSU activity under the Incentive Plan for the year ended December 31, 2015 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 Once vested, shares will be issued net of the minimum statutory tax withholding requirements to be paid by the Company on behalf of employees. As a result, the actual number of shares issued will be fewer than the actual number of RSUs outstanding. The Company recognized stock-based compensation expense of $973 , $0 and $0 in the consolidated statements of operations related to RSUs in 2015 , 2014 and 2013 , respectively. As of December 31, 2015 , total unrecognized stock-based compensation expense related to unvested RSUs, reflecting an estimated forfeiture rate, was $4,839 , which will be recognized over the remaining weighted-average life of the awards, 3.34 years . Performance Awards of Restricted Stock Units 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 equity 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. A summary of PRSU activity under the Incentive Plan for the year ended December 31, 2015 is as follows: PRSUs Number of Shares Weighted-Average Grant Date Fair Value Outstanding at December 31, 2014 — $ — Granted 955,084 2.95 Vested — — Forfeited/Cancelled — — Unvested at December 31, 2015 955,084 $ 2.95 PRSUs earned prior to the first anniversary of the grant date vest one-half upon the first anniversary of the grant date, and the remaining one-half vest ratably on a quarterly basis over a one year period thereafter. PRSUs earned subsequent to the first anniversary of the grant date vest one-half upon achievement of the corresponding stock price target, and the remaining one-half vest ratably on a quarterly basis over a one year period thereafter, contingent on continued employment on such vesting dates. Once vested, shares will be issued net of the minimum statutory tax withholding requirements to be paid by the Company on behalf of Mr. Durchslag. As a result, the actual number of shares issued will be fewer than the actual number of PRSUs outstanding. The Company recognized stock-based compensation expense of $581 , $0 and $0 in the consolidated statements of operations related to PRSUs in 2015 , 2014 and 2013 , respectively. As of December 31, 2015 , total unrecognized stock-based compensation expense related to PRSUs was $2,236 , which will be recognized over the remaining weighted-average life of the award, 1.44 years .

Income Taxes

Income Taxes	12 Months Ended

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 that 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, 2015 , 2014 and 2013 . The provision for income taxes for the years ended December 31, 2015 , 2014 and 2013 consisted of the following components: 2015 2014 2013 Current: U.S. federal $ — $ — $ — State 27 40 34 Total current 27 40 34 Deferred: U.S. federal $ 17 $ 10 $ 4 State — 1 2 Total deferred 17 11 6 Provision for income taxes $ 44 $ 51 $ 40 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, 2015 , 2014 and 2013 is as follows: 2015 2014 2013 U.S. federal income tax rate 34.0 % 34.0 % 34.0 % State income taxes, net of federal benefit (1.3 )% (0.5 )% 6.4 % Valuation allowance (29.7 )% (20.1 )% (39.7 )% Stock-based compensation 15.6 % (9.4 )% (0.4 )% Research and development credits (16.4 )% — % — % Other (1.8 )% (4.4 )% (0.4 )% Effective income tax rate 0.4 % (0.4 )% (0.1 )% Significant components of the Company’s deferred tax assets and liabilities as of December 31, 2015 and 2014 are as follows: 2015 2014 Deferred tax assets: Deferred revenue $ 34,177 $ 35,477 Intangibles - other 10,088 11,275 Net operating loss carryforwards 50,885 48,433 Stock-based compensation 5,301 3,773 Research and development credits 2,556 — Other 3,756 4,930 Total deferred tax assets 106,763 103,888 Valuation allowance (84,035 ) (89,271 ) Total net deferred tax assets 22,728 14,617 Deferred tax liabilities: Prepaid expenses $ (3,853 ) $ (4,806 ) Property, equipment and software (18,875 ) (9,811 ) Goodwill (198 ) (181 ) Total net deferred tax liabilities (22,926 ) (14,798 ) Total net deferred tax liability $ (198 ) $ (181 ) As of December 31, 2015 , the Company had net operating loss carryforwards for federal and state income tax purposes of approximately $137,626 and $176,371 , respectively. These net operating losses include an unrealized benefit of approximately $6,056 related to share-based compensation that will be recorded in equity when realized. 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, 2015 and 2014 , the Company did not have any material unrecognized income tax benefits recorded in its consolidated balance sheets.

Description of Business, Basi21

Description of Business, Basis of Presentation and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2015
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”).
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 were 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. The consolidated financial statements reflect all adjustments of a normal recurring nature considered, in the opinion of management, necessary to fairly report the results for the periods presented.
Reclassification of Prior Year Presentation	Reclassification of Prior Year Presentation Certain prior year amounts were reclassified for consistency with the current period presentation. These reclassifications did not materially impact the consolidated financial statements.
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 recognized ratably over the term of the associated subscription. Prior to 2014, the Company also generally received a one-time, nonrefundable enrollment fee at the time a member joined. Enrollment fees were deferred and are being recognized as revenue ratably over an estimated average membership life of 80 months for annual or multi-year members and 13 months for monthly members, based on historical membership experience. The Company discontinued charging one-time, nonrefundable enrollment fees in 2014.
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 and 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 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 that 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, 2015 and 2014 , the Company held $23,976 and $24,268 , 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 the associated interest and internal labor costs incurred during development. Construction in progress is 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 range from 3 to 25 years . Depreciation 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 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 additional functionality. The Company is capitalizing a portion of the interest on funds borrowed in relation to the capitalized website and software development costs incurred for the ongoing development around the Company's website and technology platform. The Company's policy with respect to capitalized interest specifies that interest costs on 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. For the year ended December 31, 2015 , total interest costs incurred amounted to $5,131 , of which $3,570 was capitalized as construction in progress for website and software development costs. For the year ended December 31, 2014 , total interest costs incurred amounted to $2,613 , of which $1,410 was capitalized as construction in progress for website and software development costs. No interest costs were capitalized for the year ended December 31, 2013 . The Company is also capitalizing internal labor costs, including compensation, benefits and payroll taxes, incurred for the ongoing capitalized website and software development project related to the Company's website and technology platform. The Company's policy with respect to capitalized internal labor stipulates that labor costs for employees working on 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. As of December 31, 2015 and 2014 , internal labor costs amounting to $11,107 and $4,410 , respectively, were capitalized as construction in progress for website and software development costs.
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 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 that 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 by 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 well as the fourth quarter of 2014 as discussed in further detail in Note 5, “Property, Equipment and Software,” of these Notes to Consolidated Financial Statements. No other adjustments to the respective carrying values of the Company's long-lived assets have been recorded to date.
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 and are being amortized into interest expense over the term of the financing agreement. 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. 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 related debt. 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 noncancellable 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 $8,573 and $11,378 as of December 31, 2015 and 2014 , 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.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation using the fair value 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 performance awards of restricted stock units (“PRSUs”), the Company recognizes stock-based compensation expense in an amount equal to the fair market value on the grant date of the respective award. The Company recognizes this expense, net of estimated forfeitures, over the requisite service period. The Company estimates the forfeiture rates utilized based on historical forfeitures of equity awards and adjusts the rates to reflect changes in facts and circumstances, if any, as deemed necessary. The Company's estimated forfeiture rates are revised if actual forfeitures differ from initial estimates. The fair value of stock options granted 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 granted is based on the fair market value of the underlying stock on the date of grant, while the the fair value of PRSUs granted is estimated as of the date of grant using a Monte Carlo option-pricing simulation model.
Commitments and Contingencies, Policy [Policy Text Block]	Loss Contingencies The Company is involved in various lawsuits, claims, investigations and proceedings. The Company records a liability when it is both probable that a loss has been incurred and the amount can be reasonably estimated. If the Company determines that 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 Sales and use tax expenses are included within operations and support expense in the consolidated statements of operations. The Company does not separately collect sales and use taxes from its members. Instead, the Company records an accrual for sales and use tax based on probable liability within 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 that 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 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 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 application 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 application 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 November 2015, the FASB issued Accounting Standards Update No. 2015-17: Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). The amendments in this update require that deferred tax assets and liabilities be presented as noncurrent in a classified balance sheet, simplifying the previous guidance, which required entities to separately present deferred tax assets and liabilities as current and noncurrent in a classified balance sheet. Under the guidance set forth in this update, companies will no longer allocate valuation allowances between current and noncurrent deferred tax assets as those allowances will also be classified as noncurrent. ASU 2015-17, which may be applied on either a retrospective or prospective basis at the option of the Company, will be effective for the Company in fiscal year 2017, but early adoption is allowed. The Company adopted ASU 2015-17 for the year ended December 31, 2015 and elected to retrospectively apply, noting no material impact to the consolidated financial statements. In April 2015, the FASB issued Accounting Standards Update No. 2015-05: Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement (“ASU 2015-05”). The amendments in this update provide guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the update specifies that the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. The update further specifies that the customer should account for a cloud computing arrangement as a service contract if the arrangement does not include a software license. ASU 2015-05 will be effective for the Company in fiscal year 2016. 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 April 2015, the FASB issued Accounting Standards Update No. 2015-03: Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). This update sets forth a requirement that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. The recognition and measurement guidance for debt issuance costs is not affected by the amendments in this update. ASU 2015-03 will be effective for the Company in fiscal year 2016. Retrospective application of the guidance set forth in this update is required, and as such, once effective, will result in a reclassification of the deferred financing fees currently recorded as a noncurrent asset within the consolidated balance sheet to a direct deduction from the carrying amount of long-term debt within noncurrent liabilities. In August 2014, the FASB issued Accounting Standards Update No. 2014-15: Presentation of Financial Statements - Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern (“ASU 2014-15”). The update sets forth a requirement for management to evaluate whether there are conditions and events that raise substantial doubt about an entity's ability to continue as a going concern, a responsibility that did not previously exist in U.S. GAAP. The amendments included in this update require management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards. Specifically, the amendments (1) provide a definition of the term substantial doubt, (2) require an evaluation every reporting period, including interim periods, (3) provide principles for considering the mitigating effect of management’s plans, (4) require certain disclosures when substantial doubt is alleviated as a result of consideration of management’s plans, (5) require an express statement and other disclosures when substantial doubt is not alleviated, and (6) require an assessment for a period of one year after the date that the financial statements are issued (or available to be issued). ASU 2014-15 will be effective for the Company in fiscal year 2016. 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”). The 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.” The update also requires significantly expanded disclosures related to revenue recognition. ASU 2014-09 will be effective for the Company in fiscal year 2018 following the issuance of ASU 2015-14 in August 2015, which deferred the effective date of ASU 2014-09 by one year. The Company is currently evaluating the future impact and method of adoption of this update with respect to the consolidated financial statements.
