Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Principles of Consolidation These consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company is not the primary beneficiary of, nor does it have a controlling financial interest in, any variable interest entity. Accordingly, the Company has not consolidated any variable interest entity. Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Such estimates include allowances for doubtful accounts and returns, valuations of deferred income taxes, long-lived assets, capitalizable software development costs and the related amortization, incremental borrowing rate used in lease accounting, the determination of the useful lives of assets, and the impairment assessment of acquired intangibles and goodwill as well as the estimates disclosed in association with revenue recognition. Determination of these transactions and account balances are based on, among other things, the Company’s estimates and judgments. These estimates are based on the Company’s knowledge of current events and actions it may undertake in the future as well as on various other assumptions that it believes to be reasonable. Actual results could differ materially from these estimates. Revenue and Deferred Revenue The Company derives its revenue primarily from fees for subscription services and professional services sold to employers and insurance carriers as well as platform revenue derived from the value of products sold on our platform. Revenue is recognized when control of these services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Taxes collected from customers relating to services and remitted to governmental authorities are excluded from revenue. The Company determines revenue recognition through the following steps: • Identification of each contract with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, performance obligations are satisfied. Software Services Revenue Software services revenue consists of subscription revenue and platform revenue. Subscription Revenue Subscription revenue primarily consists of monthly subscription fees paid to the Company by its employer and insurance carrier customers for access to, and usage of, cloud-based benefits software solutions for a specified contract term. Fees are generally charged based on the number of employees or subscribers with access to the solution. Subscription services revenue is generally recognized on a ratable basis over the contract term beginning on the date the subscription services are made available to the customer. The Company’s subscription service contracts are generally three years. Subscription revenue also includes fees paid for other services, such as event sponsorships and certain data services. Platform Revenue Platform revenue is generated from the value of policies or products enrolled in through the Company’s marketplace. Platform revenue from carriers is generally recognized over the policy period of the enrolled products. In arrangements where the Company sells policies to employees of its customers as the broker, it earns broker commissions. Revenue from insurance broker commissions and supplier transactions is recognized at a point in time when the orders for the policies are received and transferred to the insurance carrier or supplier, and is reduced by estimates for risks from collectability, policy cancellation and termination. Professional Services Revenue Professional services revenue primarily consists of fees related to the implementation of software products purchased by customers. Professional services typically include discovery, configuration and deployment, integration, testing, and training. Fees from consulting services and support services are also included in professional services revenue. The Company determined that implementation services for certain of its insurance carrier customers significantly modify or customize the software solution and, as such, do not represent a distinct performance obligation. Accordingly, revenue from such implementation services with these insurance carrier customers are generally recognized over the contract term of the associated subscription services contract, including any extension periods representing a material right. In certain arrangements, the Company utilizes estimates of hours as a measure of progress to determine revenue. Revenue from implementation services with employer customers is generally recognized as those services are performed. Revenue from support and training fees is recognized over the service period. Contracts with Multiple Performance Obligations Certain of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the individual performance obligations are accounted for separately if they are distinct. The Company allocates the transaction price to the separate performance obligations based on their relative standalone selling prices. The Company determines the standalone selling prices based on its overall pricing objectives, taking into consideration market conditions and other factors, including the value of its contracts, the subscription services sold, customer size and complexity, and the number and types of users under the contracts. Contract Costs The Company capitalizes costs to obtain contracts that are considered incremental and recoverable, such as sales commissions. Payments of sales commissions generally include multiple payments. The Company capitalizes only those payments made within an insignificant time from the contract inception, typically three months or less. Subsequent payments are expensed as incurred. The capitalized costs are amortized to sales and marketing expense over the estimated period of benefit of the asset, which is generally four to five years. The Company expenses the costs to obtain a contract when the amortization period is less than one year. Deferred costs related to obtaining contracts is included in deferred contract costs and other non-current assets. The Company capitalizes contract fulfillment costs directly associated with customer contracts that are not related to satisfying performance obligations. The costs are amortized to cost of revenue expense over the estimated period of benefit, which is generally five years. Deferred fulfillment costs are included in deferred contract costs and other non-current assets. The following tables present information about deferred contract costs: As of December 31, Balance of deferred contract costs 2019 2018 Costs to obtain contracts $ 6,676 $ 7,506 Costs to fulfill contracts $ 3,112 $ 5,235 Year ended December 31, Amortization of deferred contract costs 2019 2018 2017 Costs to obtain contracts included in sales and marketing expense $ 3,662 $ 4,217 $ 4,488 Costs to fulfill contracts included in cost of revenue $ 2,790 $ 3,480 $ 3,525 Cost of Revenue Cost of revenue primarily consists of employee compensation, professional services, data center co-location costs, networking expenses, depreciation expense for computer equipment directly associated with generating revenue, amortization expense for capitalized software development costs, and infrastructure maintenance costs. In addition, the Company allocates a portion of overhead, such as facilities and security costs, additional depreciation and amortization expense, and employee benefit costs, to cost of revenue based on headcount. Cash and Cash Equivalents Cash and cash equivalents consist of bank checking accounts and money market accounts. The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents. Concentrations of Credit Risk The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash equivalents and accounts receivable. All of the Company’s cash and cash equivalents are held at financial institutions that management believes to be of high credit quality. The bank deposits of the Company might, at times, exceed federally insured limits and are generally uninsured and uncollateralized. The Company has not experienced any losses on cash and cash equivalents to date. To manage accounts receivable risk, the Company evaluates the creditworthiness of its customers and maintains an allowance for doubtful accounts. Accounts receivable are unsecured and derived from revenue earned from customers located in the United States. One customer represented approximately 13% and 11% of total revenue for the year ended December 31, 2018 and 2017, respectively. No customer exceeded 10% of total revenue for the year ended December 31, 2019. As of December 31, 2019, one customer represented approximately 11% of total accounts receivable. No customer exceeded 10% of accounts receivable as of December 31, 2018. Accounts Receivable and Allowance for Doubtful Accounts and Returns Accounts receivable are stated at realizable value, net of allowances for doubtful accounts and returns. The Company utilizes the allowance method to provide for doubtful accounts based on management’s evaluation of the collectability of amounts due, and other relevant factors. Bad debt expense is recorded in general and administrative expense in the consolidated statements of operations and comprehensive loss. The Company’s estimate is based on historical collection experience and a review of the current status of accounts receivable. Historically, actual write-offs for uncollectible accounts have not significantly differed from the Company’s estimates. The Company removes recorded receivables and the associated allowances when they are deemed permanently uncollectible. However, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates. The allowances for returns are accounted for as reductions of revenue and are estimated based on the Company’s periodic assessment of historical experience and trends. The Company considers factors such as historical reasons for adjustments, service and delivery issues or delays, and past due customer billings. The following table presents the balances of the allowances: As of December 31, Balance of allowances 2019 2018 Allowance for doubtful accounts $ 155 $ 392 Allowance for returns $ 2,760 $ 3,191 Property and Equipment and Capitalized Software Development Costs Property and equipment, including capitalized software development costs, are stated at cost less accumulated depreciation and amortization. Expenditures for major additions and improvements are capitalized. Depreciation and amortization are recognized over the estimated useful lives of the related assets using the straight-line method. The estimated useful lives for significant property and equipment categories are generally as follows: Buildings, leased (prior to adoption of ASC 842) 30 years Developed software 3 years Computers and related equipment 3-5 years Purchased software and licenses 1-7 years Leasehold improvements Lesser of estimated useful life of asset or lease term Furniture and fixtures 7 years Other equipment 5-12 years Vehicles 5 years Useful lives of significant assets are periodically reviewed and adjusted prospectively to reflect the Company’s current estimates of the respective assets’ expected utility. Costs associated with maintenance and repairs are expensed as incurred. The Company capitalizes certain costs related to its software developed or obtained for internal use. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Internal and external costs incurred during the application development stage, including upgrades and enhancements representing modifications that will result in significant additional functionality, are capitalized. Software maintenance and training costs are expensed as incurred. Capitalized costs are recorded as part of property and equipment and are amortized on a straight-line basis over the software’s estimated useful life which is three years. The Company evaluates these assets for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Identifiable Intangible Assets Identifiable intangible assets with finite lives are recorded at their fair values at the date of acquisition and are amortized on a straight-line basis over their respective estimated useful lives, which is the period over which the asset is expected to contribute directly or indirectly to future cash flows. Impairment of Long-Lived Assets and Goodwill The Company reviews long-lived assets and definite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset might not be recoverable. Recoverability of the long-lived asset is measured by a comparison of the carrying amount of the asset or asset group to future undiscounted net cash flows expected to be generated. If such assets are not recoverable, the impairment to be recognized, if any, is measured as the amount by which the carrying amount of the assets exceeds the estimated fair value (discounted cash flow) of the assets or asset group. Assets held for sale are reported at the lower of the carrying amount or fair value, less costs to sell. Goodwill represents the excess of the aggregate of the fair value of consideration transferred in a business combination over the fair value of assets acquired, net of liabilities assumed. Goodwill is not amortized; rather, goodwill is tested for impairment at the reporting unit level as of October 31 of each year, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value before testing goodwill for impairment for each reporting unit. The reporting units are determined by the components of the Company’s operating segments that constitute a business for which both (1) discrete financial information is available and (2) segment management regularly reviews the operating results of that component. If it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs the impairment test by applying a fair-value-based test. The Company compares the fair value of a reporting unit to its carrying value. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of our reporting unit, an impairment loss is recorded equal to the difference. The Company has one reporting unit. To determine the fair value of the Company’s reporting unit, the Company has used its market capitalization. The Company may also determine fair value using discounted cash flow analysis, which requires significant assumptions and estimates about future operations. Significant judgments inherent in this analysis include the determination of an appropriate discount rate, estimated terminal value and the amount and timing of expected future cash flows. Debt Issuance Costs Debt issuance costs related to the convertible senior note financing have been recorded as a reduction of the carrying amount of the debt and are amortized to interest expense using the effective interest method. Debt issuance costs related to the revolving line of credit have been recorded in other non-current assets and are amortized to interest expense over the remaining life of the agreement. Leases (after adoption of ASC 842) The Company periodically enters into finance leases for property and equipment. The leasing arrangements for the Company’s office space at its headquarters campus are classified as finance leases. The Company also leases office space under operating leases. The Company determines if an arrangement is a lease at inception. Right of use, or ROU, assets represent the Company’s right to use an underlying asset for the lease term. Lease liabilities represent an obligation to make lease payments arising from the lease. Leases with a term of 12 months or less are not included in the recognized ROU assets and lease liabilities for all classes of assets. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Because the Company’s operating leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on information available at commencement date to determine the present value of lease payments. The ROU asset also consists of any prepaid lease payments, lease incentives, or initial direct costs. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense. The Company has lease agreements which require payments for lease and non-lease components (e.g. common area maintenance and equipment maintenance) that are accounted for as a single lease component. Variable lease payment amounts that cannot be determined at the commencement of the lease, such as maintenance costs based on future obligations, are not included in the ROU assets or liabilities. These are expensed as incurred and recorded as variable lease expense. Financing Obligations Financing obligations include liabilities for the purchase of software licenses. Prior to the adoption of ASC 842, in its build-to-suit lease arrangements where the Company is involved in the construction of its buildings, the Company is deemed the owner for accounting purposes during the construction period. The Company records an asset for the amount of the total project costs in Property and Equipment, net and the related financing obligation in Lease Liabilities and Financing obligations on the Consolidated Balance Sheet. Once construction is complete, the Company determines if the asset qualifies for sale-leaseback accounting treatment. If the arrangement does not qualify for sale-lease back treatment, the Company continues to reduce the obligation over the lease term as payments are made and depreciates the asset over its useful life. The Company does not report rent expense for the portion of the rent payment determined to be related to the assets that it owns for accounting purposes. Rather, this portion of the rent payment under the lease is recognized as a reduction of the financing obligation and as interest expense. Advertising The Company expenses advertising costs as they are incurred. Direct advertising costs for the years ended December 31, 2019, 2018 and 2017 were $332, $391 and $168, respectively. Comprehensive Loss The Company’s net loss equals comprehensive loss for all periods presented. Stock-Based Employee Compensation Stock-based employee compensation is measured based on the grant-date fair value of the awards and recognized in the Consolidated Statements of Operations and Comprehensive Loss over the period during which the award holder is required to perform services in exchange for the award, which is the vesting period. Compensation expense is recognized over the vesting period of the applicable award using the straight-line method. Compensation expense related to performance-based restricted stock units, which are accounted for as equity awards, is recognized when it is probable that the performance measure will be met. Compensation costs related to restricted stock units (“RSUs”) is based on the market price on the grant date. The Company uses the Black-Scholes option pricing model for estimating the fair value of stock options. The use of the option valuation model requires the input of subjective assumptions, including the expected life of the option and the expected stock price volatility. The Company recognizes the effect of forfeitures as they occur. The recognition of stock-based compensation expense associated with performance-based restricted stock units requires the estimation of the probability of achieving performance measures. The Company adopted the guidance in Accounting Standards Update ("ASU") 2016-09, “Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting,” on January 1, 2017. Under this ASU, entities are permitted to make an accounting policy election to either estimate forfeitures on share-based payment awards, as previously required, or to recognize forfeitures as they occur. The Company has elected to recognize forfeitures as they occur and the impact of that change in accounting policy has been recorded as a $391 cumulative effect adjustment to its accumulated deficit as of January 1, 2017. Income Taxes The Company uses the asset and liability method for income tax accounting. This method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. Valuation allowances are recorded to reduce deferred tax assets to the amount the Company believes is more likely than not to be realized. The tax benefits of uncertain tax positions are recognized only when the Company believes it is more likely than not that the tax position will be upheld on examination by the taxing authorities based on the merits of the position. The Company recognizes interest and penalties, if any, related to unrecognized income tax benefits in income tax expense. Income tax effects related to settlements of share-based payment awards are reported in earnings as an increase or decrease to income tax expense (benefit), net. Additionally, income tax-related cash flows resulting from share-based payments are reported as operating activities in the statement of cash flows. Basic and Diluted Net Loss per Common Share Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including outstanding stock options, outstanding warrants, common stock related to unvested restricted stock units and convertible senior notes to the extent dilutive, and common stock issuable pursuant to the ESPP. Basic and diluted net loss per share was the same for each period presented, as the inclusion of all potential common shares outstanding would have been anti-dilutive. Recently Adopted Accounting Standards Leases On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2016-02, “Leases (Topic 842),” codified as ASC 842. 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. ASC 842 introduces new disclosure requirements for leasing arrangements. The Company adopted this update using the modified retrospective transition method at the beginning of the period of adoption. Accordingly, the Company did not adjust prior period financial statements, and recognized a cumulative-effect adjustment to the opening balance of accumulated deficit in 2019 in the amount of $7,686. The Company utilized the following additional significant policy elections: • Elected the package of three transition practical expedients to not reassess: o whether any expired or existing contracts are or contain a lease; o the classification of any expired or existing leases; and o the treatment of initial direct costs. • Adopted a policy to not separate lease and associated nonlease components for all classes of assets. The Company applied this policy to all existing leases on transition as well as new leases going forward. • Adopted a policy to not include leases with a term of 12 months or less in the recognized ROU assets and lease liabilities for all classes of assets. The adoption of this standard had a significant impact on the Company’s consolidated financial statements as follows: • Net assets of $21,019 and related financing obligations and other noncurrent liabilities of $34,909 for existing build-to-suit lease arrangements were derecognized. These leases were transitioned to the new standard based on an analysis of the lease balances as of the transition date as if they had been leases under ASC 840. Based on this analysis, the land component of these leases was combined with the remainder of the lease obligations. Historically, these obligations were accounted for separately and recognized as part of facilities expense and allocated to cost of revenue and operating expenses. Amounts recognized included $56,422 of net ROU assets, $2,848 of net leasehold improvements, and $63,952 of total finance lease liabilities. The net cumulative adjustment to accumulated deficit to derecognize and transition these leases was $7,686. • Finance lease liabilities and ROU assets of $3,589 were recorded related to payment obligations for nonlease components (e.g. common area maintenance and equipment maintenance) associated with existing capital leases. • Operating lease liabilities and ROU assets of $1,169 were recorded related to existing operating lease obligations. Accounting Standards Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” The ASU modifies the disclosure requirements required for fair value measurements. This ASU is effective for the Company for the interim and annual reporting periods starting January 1, 2020. Early adoption is permitted. The Company does not expect this guidance to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The purpose of this ASU is to require a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. This ASU is effective for interim and annual reporting periods starting January 1, 2020. The Company expects its net accounts receivable balance to be affected by the adoption of this guidance but has not completed its quantifying of the impact on its consolidated financial statements.

Business Combinations [Abstract]
Business Combination	3. Business Combination On February 25, 2019, the Company purchased certain operating assets and liabilities, intellectual property and intangible assets, including the workforce in place, of the commercial business of Connecture, Inc., for $20,914 ($24,000 before working capital adjustments). This acquisition added technology to potentially strengthen the Company’s platform, expand its customer reach, and enhance the value the Company delivers to its carrier customers. The following table summarizes the fair value of the consideration paid and the amounts of the assets acquired and liabilities assumed recognized at the acquisition date: Consideration Transferred Cash $ 19,914 Contingent consideration arrangement 1,000 Fair value of total consideration transferred $ 20,914 Recognized Amounts of Identifiable Assets Acquired and Liabilities Assumed Accounts receivable, net $ 912 Contract, prepaid and other current assets 611 Property and equipment, net 198 Operating lease right-of-use assets 1,107 Intangible assets, net 14,600 Deferred contract costs and other non-current assets 250 Accrued expenses (2 ) Accrued compensation and benefits (186 ) Deferred revenue, current portion (6,692 ) Operating lease ROU liabilities, current portion (84 ) Operating lease ROU liabilities, net of current portion (1,023 ) Total identifiable net assets 9,691 Goodwill 11,223 Total identifiable net assets and goodwill $ 20,914 The goodwill of $11,223 arising from the acquisition consists largely of the value of the acquired organized workforce as well as economies of scale. The Company expects all of the goodwill recognized to be deductible for income tax purposes after satisfying performance obligations for certain customers. The identifiable intangible assets acquired have a weighted average amortization period of 6.5 years and include developed technology, customer relationships, and trade name. The Company did not acquire any contingent liabilities as part of the transaction. The cash transferred includes $1,000 in contingent consideration placed into a third-party escrow. These escrowed funds were to be released to Connecture as required contractual consents to the assignment of service arrangements are obtained from specified customers. The undiscounted consideration distributable to Connecture under this arrangement ranges from $0 to $1,000. As customer consents are obtained, the amount of the undiscounted consideration associated with the customer is transferred to Connecture. For any specified service contracts that, at the end of one year, are continuing to be honored by the customer, whether or not affirmative consent has been received from such customer, the related escrowed funds will be distributed to Connecture. If during the first year after the closing date of the acquisition, a customer refuses to consent to the assignment of the contract, or fails to deliver consent and stops performing under the contract or otherwise terminates the contract, the portion of the escrow related to that customer contract will then be distributable back to the Company. The Company expected all of the contingent consideration would be distributed to Connecture within one year of acquisition. Therefore, the full $1,000 undiscounted escrow balance is included in the fair value of the consideration transferred for the acquisition. As of December 31, 2019, all of these escrow funds had been released to Connecture. The fair value of the assets and liabilities assumed is provisional pending finalization of the Company’s review of supporting records for these assets and liabilities. The Company incurred $450 in costs related to completing the acquisition, all of which were recognized in general and administrative expense during the year ended December 31, 2019. Revenue recognized by the Company related to the operations of the acquired business were $23,855 for the year ended December 31, 2019. During the third quarter of 2019, the Company had integrated the acquired assets and workforce into its operations, which decreased the Company’s ability to identify incremental costs associated with the acquired business. Identifiable expenses associated with the acquired business were $20,219 for the year ended December 31, 2019. Coincident with the acquisition, the Company entered into two additional agreements with Connecture each of which are accounted for separately at contracted prices as described below: • Transition Services Agreement where each party provides certain transition services to the other for a 12-month period to facilitate an orderly transition the acquired business. During the year ended December 31, 2019, the Company recognized operating expense of $559 related to this agreement. • An agreement for the Company to provide interim services to Connecture as a subcontractor under a master services agreement maintained by Connecture that includes service commitments related to both the acquired business and Connecture’s retained business while the parties work together with the customer to legally separate the contract. During the year ended December 31, 2019, the Company recognized revenue of $979 related to this agreement. Supplemental pro forma revenue and earnings information are not presented because historical records for the acquired business are not available. Therefore, determining the amount of revenue and earnings of the combined entity as though the business combination had occurred as of the beginning of the comparable periods would require significant estimates of amounts that the Company cannot independently substantiate. The Company estimates that the difference between pro forma information compared to reported results would not be significant.

Fair Value Disclosures [Abstract]
Fair Value Measurement	5. Fair Value Measurement The carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, net accounts receivable, accounts payable and other accrued liabilities, and accrued compensation and benefits, approximate fair value due to their short-term nature. The carrying value of the Company’s financing obligations and revolving line of credit approximates fair value, considering the borrowing rates currently available to the Company for financing obligations with similar terms and credit risks. The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The hierarchy requires the Company to use observable inputs when available, and to minimize the use of unobservable inputs when determining fair value. The three tiers are defined as follows: Level 1. Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2. Other inputs that are directly or indirectly observable in the marketplace. Level 3. Unobservable inputs for which there is little or no market data, which require the Company to develop its own assumptions. Assets and Liabilities Measured at Fair Value on a Recurring Basis The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level to classify them for each reporting period. This determination requires significant judgments to be made. The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis using the above categories, as of December 31, 2019 and 2018. December 31, 2019 Description Level 1 Level 2 Level 3 Total Cash Equivalents: Money market mutual funds (1) $ 124,503 $ - $ - $ 124,503 Total assets $ 124,503 $ - $ - $ 124,503 December 31, 2018 Description Level 1 Level 2 Level 3 Total Cash Equivalents: Money market mutual funds (1) $ 182,748 $ - $ - $ 182,748 Total assets $ 182,748 $ - $ - $ 182,748 (1) Money market mutual funds are classified as cash equivalents in the Company’s consolidated balance sheets. As short-term, highly liquid investments readily convertible to known amounts of cash, with remaining maturities of three months or less at the time of purchase, the Company’s cash equivalent money market funds have carrying values that approximate fair value.

Convertible Senior Notes

Convertible Senior Notes	12 Months Ended

Debt Disclosure [Abstract]
Convertible Senior Notes	8. Convertible Senior Notes In December 2018, the Company issued $240,000 aggregate principal amount of 1.25% convertible senior notes (“Notes”) due December 15, 2023, unless earlier repurchased by the Company or converted by the holder pursuant to their terms. Interest is payable semiannually in arrears on June 15 and December 15 of each year, commencing on June 15, 2019. The Notes are governed by an Indenture between the Company, as issuer, and U.S. Bank, National Association, as trustee. The Notes are unsecured and rank: senior in right of payment to the Company’s future indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to the Company’s unsecured indebtedness that is not so subordinated; effectively junior in right of payment to any of the Company’s senior, secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities incurred by the Company’s subsidiaries. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of common stock, at the Company’s election. The Notes have an initial conversion rate of 18.8076 shares of common stock per $1 principal amount of Notes. This represents an initial effective conversion price of approximately $53.17 per share of common stock and 4,513,824 shares issuable upon conversion. Throughout the term of the Notes, the conversion rate may be adjusted upon the occurrence of certain events. Holders of the Notes will not receive any cash payment representing accrued and unpaid interest, if any, upon conversion of a Note, except in limited circumstances. Accrued but unpaid interest will be deemed to be paid by cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock paid or delivered, as the case may be, to the holder upon conversion of Notes. Prior to the close of business on September 14, 2023, the Notes will be convertible at the option of holders during certain periods, only upon satisfaction of certain conditions set forth below. On or after September 15, 2023, until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes at the conversion price at any time regardless of whether the conditions set forth below have been met. Holders may convert all or a portion of their Notes prior to the close of business on September 14, 2023, in multiples of $1 principal amount, only under the following circumstances: • during any calendar quarter commencing after the calendar quarter ending on March 31, 2019 (and only during such calendar quarter), if the last reported sales price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price on each applicable trading day; • during the five business day period after any five consecutive trading day period, or the Notes measurement period, in which the “trading price” (as defined in the Indenture) per $1 principal amount of notes for each trading day of the Notes measurement period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate on each such trading day; • if the Company calls any or all of the Notes for redemption, at any time prior to the close of business on September 14, 2023; or • upon the occurrence of specified corporate events. As of December 31, 2019, the Notes are not yet convertible. Based on market data available for publicly traded, senior, unsecured corporate bonds issued by companies in the same industry and with similar maturity, the Company estimated the implied market interest rate of its Notes to be approximately 7.30%, assuming no conversion option. Assumptions used in the estimate represent what market participants would use in pricing the liability component of the Notes, including market interest rates, credit standing, and yield curves, all of which are defined as Level 2 observable inputs. The estimated implied interest rate was applied to the Notes, which resulted in a fair value of the liability component of $181,500 upon issuance, calculated as the present value of future contractual payments based on the $240,000 aggregate principal amount. The excess of the principal amount of the liability component over its carrying amount, or the debt discount, is amortized to interest expense over the term of the Notes. The $58,500 difference between the In accounting for the transaction costs related to the issuance of the Notes, the Company allocated the total amount incurred to the liability and equity components in proportion to the allocation of proceeds. Transaction costs attributable to the liability component, totaling $4,808, are being amortized to expense over the term of the Notes, and transaction costs attributable to the equity component, totaling $1,550, and were included with the equity component in shareholders’ equity. The Notes consist of the following as of December 31: 2019 2018 Liability Component: Principal $ 240,000 $ 240,000 Less: debt discount, net of amortization (52,051 ) (63,308 ) Net carrying amount $ 187,949 $ 176,692 Equity component (a) 56,950 56,950 (a) Recorded in the consolidated balance sheet within additional paid-in capital, net of $1,550 transaction costs in equity. The following table sets forth total interest expense recognized related to the Notes: Year Ended December 31, 2019 2018 1.25% coupon $ 3,000 $ 42 Amortization of debt discount and transaction costs 11,256 - $ 14,256 $ 42 As of December 31, 2019, the fair value of the Notes, which was determined based on inputs that are observable in the market or that could be derived from, or corroborated with, observable market data, quoted price of the Notes in an over-the-counter market (Level 2), and carrying value of debt instruments (carrying value excludes the equity component of the Company’s convertible notes classified in equity) were as follows: December 31, 2019 December 31, 2018 Fair Value Carrying Value Fair Value Carrying Value Convertible senior notes $ 207,600 $ 187,949 $ 254,400 $ 176,692 In connection with the issuance of the Notes, the Company entered into capped call transactions with certain counterparties affiliated with the initial purchasers and others. The capped call transactions are expected to reduce potential dilution of earnings per share upon conversion of the Notes. Under the capped call transactions, the Company purchased capped call options that in the aggregate relate to the total number of shares of the Company’s common stock underlying the Notes, with an initial strike price of approximately $53.17 per share, which corresponds to the initial conversion price of the Notes and is subject to anti-dilution adjustments substantially similar to those applicable to the conversion rate of the Notes, and have a cap price of approximately $89.98. The cost of the purchased capped calls of $33,024 was recorded to stockholders’ deficit and will not be re-measured. Based on the closing price of our common stock of $21.94 on December 31, 2019, the if-converted value of the Notes was less than their respective principal amounts.

Revolving Line of Credit

Revolving Line of Credit	12 Months Ended

Debt Disclosure [Abstract]
Revolving Line of Credit	9. Revolving Line of Credit In February 2015, the Company executed a loan and security agreement with a syndicate of lenders led by Silicon Valley Bank for a senior revolving credit agreement (“Senior Revolver”) to replace its then current revolving line of credit. Debt issuance fees of $591 were capitalized in the Company’s balance sheet and are amortized over the life of the Senior Revolver. The Senior Revolver had an original borrowing limit of $60,000 and an original term of three years. Borrowing capacity under the Senior Revolver is subject to a borrowing base limit that is a function of the Company’s monthly recurring revenue as adjusted to reflect lost customer revenue during the previous three calendar months. Therefore, credit available under the Senior Revolver may be less than the borrowing limit. Interest is payable monthly. Advances under the Senior Revolver bear interest at the prime rate as published in the Wall Street Journal plus a margin based on the Company’s liquidity, which originally ranged between 1.0% and 1.5%. The Company is charged an unused line fee under this arrangement at a rate based on its liquidity, which was originally 0.300% to 0.375% per year. Any outstanding principal is due at the end of the term. In 2016, the Company amended its Senior Revolver agreement. The amendments, among other things, increased the borrowing capacity to $95,000, extended the termination date of the facility to February 20, 2020, added Goldman Sachs Lending Partners LLC to the lending syndicate and revised certain covenants including those related to accounts receivable, Minimum Consolidated EBITDA requirements, Indebtedness, permitted Indebtedness and certain capital expenditure limits. Additionally, the amendments altered definitions in the Senior Revolver agreement, including Alternate Base Rate, Applicable Margin, Consolidated EBITDA, Liquidity and Commitment Fee Rate. As a result of certain of these definitional changes, the Alternate Base Rate was modified to be the prime rate as published in the Wall Street Journal plus a margin based on our liquidity that ranges between 0.75% and 1.25%. The amendments further waived any default that may have occurred as a result of certain Indebtedness previously incurred by the Company and the disclosure to the lenders of registered Intellectual Property. In connection with the amendments, debt issuance fees of $379 were capitalized in the Company’s balance sheet and are being amortized over the remaining life of the Senior Revolver. The Company further amended its Senior Revolver agreement in April 2017 to adjust terms in the agreement to accommodate changes in its business. In March 2018, the Company amended its Senior Revolver to modify certain terms and requirements to account for the Company’s adoption of Topic 606. The Company amended its Senior Revolver again in December 2018. The amendment altered definitions and amended sections of the agreement to allow for transactions required to administer the convertible senior note financing. The Company is bound by customary affirmative and negative covenants in connection with the Senior Revolver agreement, including financial covenants related to liquidity and EBITDA. In the event of a default, the lenders may declare all obligations immediately due and stop advancing money or extending credit under the line of credit. The line of credit is collateralized by substantially all of the Company’s tangible and intangible assets, including intellectual property and the equity of subsidiaries. During the years ended December 31, 2018 and 2017, the Company borrowed an aggregate of $115,000 and $105,000, respectively, under the Senior Revolver for general operating purposes and repaid an aggregate of $171,246 and $89,000, respectively. No amounts were borrowed or repaid during the year ended December 31, 2019. As of December 31, 2019, there were no amounts outstanding under the Senior Revolver and the amount available to borrow was $88,541.

Supplemental cash flow information related to the Company’s operating and finance leases was as follows: Cash Paid for Amounts Included in the Measurement of Lease Liabilities Year Ended December 31, 2019 Financing cash flows from finance leases $ 5,884 Operating cash flows from finance leases $ 8,527 Operating cash flows from operating leases $ 599 ROU Assets Obtained in Exchange for New Lease Obligations Finance lease liabilities $ 4,248 Operating lease liabilities $ 1,107 As of December 31, 2019, the Company had no additional significant operating or finance leases that had not yet commenced. Operating Leases The Company leases office facilities under various non-cancelable operating lease agreements with original lease periods expiring between 2020 and 2027. Some of the leases provide for renewal terms at the Company’s option. Certain future minimum lease payments due under these operating lease agreements contain free rent periods or escalating rent payment provisions. These leases generally do not contain purchase options. Lease expense is recognized on a straight-line basis over the lease term as an operating expense. The components of operating lease expense were as follows: Year Ended December 31, 2019 Fixed operating lease expense $ 705 Short-term lease expense 33 Variable operating lease expense 145 Total operating lease expense 883 Sublease income (28 ) Total operating lease cost $ 855 The following table presents the lease balances within the Consolidated Balance Sheet, weighted average remaining lease term, and weighted average discount rates related to the Company’s operating leases: Lease Assets and Liabilities Classification As of December 31, 2019 Assets Operating lease ROU asset - Buildings Operating lease right-of-use assets $ 1,715 Liabilities Operating lease ROU liabilities, current portion Lease liabilities, current $ 343 Operating lease ROU liabilities, net of current portion Lease liabilities, non-current 1,568 Total operating lease liabilities $ 1,911 Weighted average remaining lease term (in years) 5.86 Weighted average discount rate 5.96 % The following table presents the maturity of the Company’s operating lease liabilities as of December 31, 2019: Operating Leases Year Ending December 31, 2020 $ 445 2021 385 2022 391 2023 398 2024 175 Thereafter 485 Total minimum lease payments 2,279 Less: imputed interest (368 ) Total operating lease liabilities $ 1,911 Finance Leases The Company leases three buildings on its Charleston, South Carolina campus. Under ASC 840, one leasing arrangement was accounted for as a capital lease while the remaining two lease agreements were accounted for as build-to-suit, failed sale-leaseback arrangements. Accordingly, the Company recognized liabilities for the lease payments related to these two buildings, which were recorded as financing obligations. Pursuant to ASC 842, the assets and related financing obligations for the existing build-to-suit lease arrangements were derecognized with a cumulative adjustment of $7,686 to accumulated deficit. These leases were transitioned to the new standard based on an analysis of the lease balances as of the transition date as if they had been a lease under ASC 840. Based on this analysis, the land components of these leases were combined with the remainder of the lease obligation whereas this obligation was previously accounted for separately and recognized as part of facility expense. To calculate the present value of lease payments, the Company used an incremental borrowing rate based on third-party valuation results as of December 2016. All three leasing arrangements are classified as finance leases under ASC 842. As a result of the adoption of ASC 842, operating expenses increased as depreciation expense related to the buildings increased due to shortening the period of depreciation from the estimated life of the asset to the expected term of the lease. Additionally, interest expense decreased as a result of a discount rate that is lower than the rate required for build-to-suit accounting. Additional information regarding these three leases is incorporated in the following disclosures. The Company has entered into various purchase agreements to obtain property and equipment for operations that are accounted for as finance leases. These arrangements have original terms ranging from 3 to 5 years with interest rates ranging from 5.25% to 14.09%. The leases are secured by the underlying leased property and equipment. The components of finance lease expense were as follows: Year Ended December 31, 2019 Amortization of ROU assets $ 8,599 Interest on lease liabilities 8,535 Variable finance lease expense 53 Total finance lease expense $ 17,187 The following table presents the lease balances within the Consolidated Balance Sheet, weighted average remaining lease term, and weighted average discount rates related to the Company’s finance leases: Lease Assets and Liabilities Classification As of December 31, 2019 Assets Finance lease ROU asset Finance lease right-of-use assets, net $ 87,067 Finance lease ROU accumulated amortization Finance lease right-of-use assets, net (8,547 ) Finance lease ROU assets, net $ 78,520 Liabilities Finance lease ROU liabilities, current portion Lease liabilities, current $ 5,315 Finance lease ROU liabilities, net of current portion Lease liabilities, non-current 86,284 Total finance lease liabilities $ 91,599 Weighted average remaining lease term (in years) 11.34 Weighted average discount rate 9.26 % The following table presents the maturity of the Company’s finance lease liabilities as of December 31, 2019: Finance Leases Year Ending December 31, 2020 $ 13,474 2021 12,942 2022 12,218 2023 11,553 2024 11,696 Thereafter 91,964 Total minimum lease payments 153,847 Less: imputed interest (62,248 ) Total finance lease liabilities $ 91,599 Financing Obligations Financing obligations were $1,933 and $37,544, as of December 31, 2019 and 2018, respectively, and consist primarily of obligations for software support for 2019 and, prior to the adoption of ASC 842, build-to-suit lease arrangements for 2018. Contractual Commitments In March 2019, the Company terminated its cancellable lease agreement to build additional office space on its headquarters campus. The Company also has $2,067 of non-cancellable contractual commitments as of December 31, 2019 related to the purchase of software and maintenance. These commitments are not accrued in the consolidated balance sheet of the Company. Legal Contingencies The Company may become a party to a variety of legal proceedings that arise in the normal course of business. While the results of such normal course legal proceedings cannot be predicted with certainty, management believes, based on current knowledge, that the final outcome of any matters will not have a material adverse effect on the Company’s business, financial position, results of operations or cash flows.

The 2012 Plan, effective on January 31, 2012, serves as the successor to the 2000 Plan and permits the granting of incentive stock options, non-statutory stock options, stock bonuses, stock purchase rights, stock appreciation rights, and restricted stock units and awards. No new awards can be issued under the 2000 Plan after the effective date of the 2012 Plan. Outstanding awards under the 2000 Plan continue to be subject to the terms and conditions of the 2000 Plan. Shares available for grant under the 2000 Plan, which were reserved but not issued or subject to outstanding awards under the 2000 Plan as of the effective date, were added to the reserves of the 2012 Plan. As of December 31, 2019, the Company had 3,189,756 shares allocated to the 2012 Plan, but not yet issued. The Company has issued two types of awards under these plans: stock options and restricted stock units (“RSUs”). The following table sets forth the number of awards outstanding for each award type is as follows: Outstanding at December 31, Award type 2019 2018 2017 Restricted stock units 1,970,555 2,174,250 1,937,014 Stock options 206,447 233,247 263,155 The grant date value of RSUs is equal to the closing price of the Company’s stock on the date of grant, or, if not a trading day, the closing price of the previous trading day. Stock options are granted at exercise prices not less than the estimated fair market value of the Company’s common stock at the date of grant. Generally, the Company issues previously unissued shares for the exercise of stock options or exchange of RSUs; however, previously acquired shares may be reissued to satisfy future issuances. The standard vesting period for RSU and option awards is over four years however vesting periods range from one to five years. Some RSUs vest immediately upon grant. The options expire 10 years from the grant date. Compensation expense for the fair value of the stock-based awards at their grant date is recognized ratably over the vesting period. Compensation expense related to stock-based awards is included in the following line items in the accompanying consolidated statements of operations and comprehensive loss for the years ended December 31: 2019 2018 2017 Cost of revenue $ 3,569 $ 5,164 $ 2,508 Sales and marketing 3,799 6,764 4,953 Research and development 3,265 5,510 2,990 General and administrative 8,939 11,430 5,686 $ 19,572 $ 28,868 $ 16,137 The total compensation cost related to non-vested awards not yet recognized as of December 31, 2019 was $31,629 and will be recognized over a weighted-average period of approximately 2.65 years. Restricted Stock Units During 2019, the Company granted RSUs under the 2012 Plan. Restricted stock units granted to employees vest in equal annual installments over terms that range from immediate vesting at grant to 4 years. The fair value of the stock at the time of grant is amortized based on a straight-line basis over the vesting period.

The valuation allowance increased by $20,209 and decreased by $6,785 during the years ended December 31, 2019 and 2018, respectively. The valuation allowance increased in 2019 resulted primarily from changes in the deferred tax assets related to the net operating loss carryforwards and deferred revenue. The decrease in the valuation allowance in 2018 resulted primarily from establishing deferred tax liabilities related to tax method changes and convertible debt issuance partially offset by changes in the deferred tax assets related to the net operating loss carryforwards. Net operating loss carryforwards for federal income tax purposes were approximately $327,415 and $287,686 at December 31, 2019 and 2018, respectively. State net operating loss carryforwards were $325,106 and $285,377 at December 31, 2019 and 2018, respectively. The federal and state net operating loss carryforwards will expire at various dates during 2020 through 2038, if not utilized. Net operating loss carryforwards and credit carryforwards reflected above may be limited due to historical and future ownership changes. South Carolina jobs tax credit and headquarters tax credit carryovers of $11,309 and $10,483 were available at December 31, 2019 and 2018, respectively. Headquarters credits are expected to be used to offset future state income tax license fees. The credits expire in various amounts during 2020 through 2034.

Subsequent Events [Abstract]
Subsequent Events	19. Subsequent Events Stock-Based Compensation During January and February 2020, the Company granted 36,772 restricted stock units to employees with an aggregate grant date fair value of $733. These restricted stock units generally vest in equal annual installments generally over 3 and 4 years from the grant date. The Company amortizes the fair value of the stock subject to the restricted stock units at the time of grant on a straight-line basis over the period of vesting. During January and February 2020, stock option exercises and vesting of restricted stock units resulted in the issuance of 30,498 shares of common stock. Revolving Line of Credit On February 20, 2020, the Company’s Senior Revolver expired. Other than unused line fees, which have all been paid, there was no outstanding indebtedness under the Senior Revolver when it expired. On March 3, 2020, the Company entered into a new credit facility and revolving line of credit agreement with Silicon Valley Bank. The three-year agreement has a borrowing limit of $50,000, with the ability for the Company to increase it to up to $100,000. Interest is payable monthly. Advances under the agreement bear interest at (a) the higher of (i) the prime rate as published in the Wall Street Journal or (ii) the federal funds effective rate plus 0.50%, plus (b) an applicable margin ranging from (0.50%) to 0.50% based on the Company’s Average Daily Usage (“ADU”) of the credit facility in the preceding month. The Company also is charged for amounts unused under this arrangement at a rate ranging from 0.00% to 0.40% based on the Company’s ADU in the preceding month. Any outstanding principal is due at the end of the term. The obligations of the Company under the new credit facility are secured by a first priority lien (subject to certain permitted liens) in substantially all of their respective personal property assets pursuant to the terms of a Guarantee and Collateral Agreement, dated March 3, 2020 and the other security documents. The new credit facility contains customary representations and warranties and restrictive covenants. In addition, the Company are required to maintain a Consolidated Adjusted Quick Ratio (“AQR”) of (i) Consolidated Quick Assets to (ii) Consolidated Current Liabilities minus the current portion of Deferred Revenue of at least 1.25 to 1.00 as of the last day of any fiscal quarter, and, if the AQR is less than 2.00 to 1.00, a Minimum Consolidated EBITDA of at least $1.00 for any such fiscal quarter calculated on a trailing 12 month basis. The Company has also agreed to fiscal year dollar limits on its capital expenditures. The new credit facility contains customary events of default, including payment and covenant defaults (subject to grace and cure periods), breaches of representations and warranties, defaults under certain other indebtedness, change of control, insolvency events, and the occurrence of a material adverse effect. If an event of default occurs, the lender would be entitled to take various actions, including the acceleration of amounts due under the credit facility and all actions permitted to be taken by a secured creditor.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation These consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The Company is not the primary beneficiary of, nor does it have a controlling financial interest in, any variable interest entity. Accordingly, the Company has not consolidated any variable interest entity.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Such estimates include allowances for doubtful accounts and returns, valuations of deferred income taxes, long-lived assets, capitalizable software development costs and the related amortization, incremental borrowing rate used in lease accounting, the determination of the useful lives of assets, and the impairment assessment of acquired intangibles and goodwill as well as the estimates disclosed in association with revenue recognition. Determination of these transactions and account balances are based on, among other things, the Company’s estimates and judgments. These estimates are based on the Company’s knowledge of current events and actions it may undertake in the future as well as on various other assumptions that it believes to be reasonable. Actual results could differ materially from these estimates.
Revenue and Deferred Revenue	Revenue and Deferred Revenue The Company derives its revenue primarily from fees for subscription services and professional services sold to employers and insurance carriers as well as platform revenue derived from the value of products sold on our platform. Revenue is recognized when control of these services is transferred to customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those services. Taxes collected from customers relating to services and remitted to governmental authorities are excluded from revenue. The Company determines revenue recognition through the following steps: • Identification of each contract with a customer; • Identification of the performance obligations in the contract; • Determination of the transaction price; • Allocation of the transaction price to the performance obligations in the contract; and • Recognition of revenue when, or as, performance obligations are satisfied. Software Services Revenue Software services revenue consists of subscription revenue and platform revenue. Subscription Revenue Subscription revenue primarily consists of monthly subscription fees paid to the Company by its employer and insurance carrier customers for access to, and usage of, cloud-based benefits software solutions for a specified contract term. Fees are generally charged based on the number of employees or subscribers with access to the solution. Subscription services revenue is generally recognized on a ratable basis over the contract term beginning on the date the subscription services are made available to the customer. The Company’s subscription service contracts are generally three years. Subscription revenue also includes fees paid for other services, such as event sponsorships and certain data services. Platform Revenue Platform revenue is generated from the value of policies or products enrolled in through the Company’s marketplace. Platform revenue from carriers is generally recognized over the policy period of the enrolled products. In arrangements where the Company sells policies to employees of its customers as the broker, it earns broker commissions. Revenue from insurance broker commissions and supplier transactions is recognized at a point in time when the orders for the policies are received and transferred to the insurance carrier or supplier, and is reduced by estimates for risks from collectability, policy cancellation and termination. Professional Services Revenue Professional services revenue primarily consists of fees related to the implementation of software products purchased by customers. Professional services typically include discovery, configuration and deployment, integration, testing, and training. Fees from consulting services and support services are also included in professional services revenue. The Company determined that implementation services for certain of its insurance carrier customers significantly modify or customize the software solution and, as such, do not represent a distinct performance obligation. Accordingly, revenue from such implementation services with these insurance carrier customers are generally recognized over the contract term of the associated subscription services contract, including any extension periods representing a material right. In certain arrangements, the Company utilizes estimates of hours as a measure of progress to determine revenue. Revenue from implementation services with employer customers is generally recognized as those services are performed. Revenue from support and training fees is recognized over the service period. Contracts with Multiple Performance Obligations Certain of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the individual performance obligations are accounted for separately if they are distinct. The Company allocates the transaction price to the separate performance obligations based on their relative standalone selling prices. The Company determines the standalone selling prices based on its overall pricing objectives, taking into consideration market conditions and other factors, including the value of its contracts, the subscription services sold, customer size and complexity, and the number and types of users under the contracts.
Contract Costs	Contract Costs The Company capitalizes costs to obtain contracts that are considered incremental and recoverable, such as sales commissions. Payments of sales commissions generally include multiple payments. The Company capitalizes only those payments made within an insignificant time from the contract inception, typically three months or less. Subsequent payments are expensed as incurred. The capitalized costs are amortized to sales and marketing expense over the estimated period of benefit of the asset, which is generally four to five years. The Company expenses the costs to obtain a contract when the amortization period is less than one year. Deferred costs related to obtaining contracts is included in deferred contract costs and other non-current assets. The Company capitalizes contract fulfillment costs directly associated with customer contracts that are not related to satisfying performance obligations. The costs are amortized to cost of revenue expense over the estimated period of benefit, which is generally five years. Deferred fulfillment costs are included in deferred contract costs and other non-current assets. The following tables present information about deferred contract costs: As of December 31, Balance of deferred contract costs 2019 2018 Costs to obtain contracts $ 6,676 $ 7,506 Costs to fulfill contracts $ 3,112 $ 5,235 Year ended December 31, Amortization of deferred contract costs 2019 2018 2017 Costs to obtain contracts included in sales and marketing expense $ 3,662 $ 4,217 $ 4,488 Costs to fulfill contracts included in cost of revenue $ 2,790 $ 3,480 $ 3,525
Cost of Revenue	Cost of Revenue Cost of revenue primarily consists of employee compensation, professional services, data center co-location costs, networking expenses, depreciation expense for computer equipment directly associated with generating revenue, amortization expense for capitalized software development costs, and infrastructure maintenance costs. In addition, the Company allocates a portion of overhead, such as facilities and security costs, additional depreciation and amortization expense, and employee benefit costs, to cost of revenue based on headcount.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of bank checking accounts and money market accounts. The Company considers all highly liquid investments with original maturities of three months or less at the time of purchase to be cash equivalents.
Concentrations of Credit Risk	Concentrations of Credit Risk The Company’s financial instruments that are exposed to concentrations of credit risk consist primarily of cash equivalents and accounts receivable. All of the Company’s cash and cash equivalents are held at financial institutions that management believes to be of high credit quality. The bank deposits of the Company might, at times, exceed federally insured limits and are generally uninsured and uncollateralized. The Company has not experienced any losses on cash and cash equivalents to date. To manage accounts receivable risk, the Company evaluates the creditworthiness of its customers and maintains an allowance for doubtful accounts. Accounts receivable are unsecured and derived from revenue earned from customers located in the United States. One customer represented approximately 13% and 11% of total revenue for the year ended December 31, 2018 and 2017, respectively. No customer exceeded 10% of total revenue for the year ended December 31, 2019. As of December 31, 2019, one customer represented approximately 11% of total accounts receivable. No customer exceeded 10% of accounts receivable as of December 31, 2018.
Accounts Receivable and Allowance for Doubtful Accounts and Returns	Accounts Receivable and Allowance for Doubtful Accounts and Returns Accounts receivable are stated at realizable value, net of allowances for doubtful accounts and returns. The Company utilizes the allowance method to provide for doubtful accounts based on management’s evaluation of the collectability of amounts due, and other relevant factors. Bad debt expense is recorded in general and administrative expense in the consolidated statements of operations and comprehensive loss. The Company’s estimate is based on historical collection experience and a review of the current status of accounts receivable. Historically, actual write-offs for uncollectible accounts have not significantly differed from the Company’s estimates. The Company removes recorded receivables and the associated allowances when they are deemed permanently uncollectible. However, higher than expected bad debts may result in future write-offs that are greater than the Company’s estimates. The allowances for returns are accounted for as reductions of revenue and are estimated based on the Company’s periodic assessment of historical experience and trends. The Company considers factors such as historical reasons for adjustments, service and delivery issues or delays, and past due customer billings. The following table presents the balances of the allowances: As of December 31, Balance of allowances 2019 2018 Allowance for doubtful accounts $ 155 $ 392 Allowance for returns $ 2,760 $ 3,191
Property and Equipment and Capitalized Software Development Costs	Property and Equipment and Capitalized Software Development Costs Property and equipment, including capitalized software development costs, are stated at cost less accumulated depreciation and amortization. Expenditures for major additions and improvements are capitalized. Depreciation and amortization are recognized over the estimated useful lives of the related assets using the straight-line method. The estimated useful lives for significant property and equipment categories are generally as follows: Buildings, leased (prior to adoption of ASC 842) 30 years Developed software 3 years Computers and related equipment 3-5 years Purchased software and licenses 1-7 years Leasehold improvements Lesser of estimated useful life of asset or lease term Furniture and fixtures 7 years Other equipment 5-12 years Vehicles 5 years Useful lives of significant assets are periodically reviewed and adjusted prospectively to reflect the Company’s current estimates of the respective assets’ expected utility. Costs associated with maintenance and repairs are expensed as incurred. The Company capitalizes certain costs related to its software developed or obtained for internal use. Costs related to preliminary project activities and post-implementation activities are expensed as incurred. Internal and external costs incurred during the application development stage, including upgrades and enhancements representing modifications that will result in significant additional functionality, are capitalized. Software maintenance and training costs are expensed as incurred. Capitalized costs are recorded as part of property and equipment and are amortized on a straight-line basis over the software’s estimated useful life which is three years. The Company evaluates these assets for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets.
Identifiable Intangible Assets	Identifiable Intangible Assets Identifiable intangible assets with finite lives are recorded at their fair values at the date of acquisition and are amortized on a straight-line basis over their respective estimated useful lives, which is the period over which the asset is expected to contribute directly or indirectly to future cash flows.
Impairment of Long-Lived Assets and Goodwill	Impairment of Long-Lived Assets and Goodwill The Company reviews long-lived assets and definite-lived intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset might not be recoverable. Recoverability of the long-lived asset is measured by a comparison of the carrying amount of the asset or asset group to future undiscounted net cash flows expected to be generated. If such assets are not recoverable, the impairment to be recognized, if any, is measured as the amount by which the carrying amount of the assets exceeds the estimated fair value (discounted cash flow) of the assets or asset group. Assets held for sale are reported at the lower of the carrying amount or fair value, less costs to sell. Goodwill represents the excess of the aggregate of the fair value of consideration transferred in a business combination over the fair value of assets acquired, net of liabilities assumed. Goodwill is not amortized; rather, goodwill is tested for impairment at the reporting unit level as of October 31 of each year, or more frequently if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. The Company performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value before testing goodwill for impairment for each reporting unit. The reporting units are determined by the components of the Company’s operating segments that constitute a business for which both (1) discrete financial information is available and (2) segment management regularly reviews the operating results of that component. If it is more likely than not that the fair value of a reporting unit is less than its carrying value, the Company performs the impairment test by applying a fair-value-based test. The Company compares the fair value of a reporting unit to its carrying value. If the carrying value of the net assets assigned to the reporting unit exceeds the fair value of our reporting unit, an impairment loss is recorded equal to the difference. The Company has one reporting unit. To determine the fair value of the Company’s reporting unit, the Company has used its market capitalization. The Company may also determine fair value using discounted cash flow analysis, which requires significant assumptions and estimates about future operations. Significant judgments inherent in this analysis include the determination of an appropriate discount rate, estimated terminal value and the amount and timing of expected future cash flows.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs related to the convertible senior note financing have been recorded as a reduction of the carrying amount of the debt and are amortized to interest expense using the effective interest method. Debt issuance costs related to the revolving line of credit have been recorded in other non-current assets and are amortized to interest expense over the remaining life of the agreement.
Leases	Leases (after adoption of ASC 842) The Company periodically enters into finance leases for property and equipment. The leasing arrangements for the Company’s office space at its headquarters campus are classified as finance leases. The Company also leases office space under operating leases. The Company determines if an arrangement is a lease at inception. Right of use, or ROU, assets represent the Company’s right to use an underlying asset for the lease term. Lease liabilities represent an obligation to make lease payments arising from the lease. Leases with a term of 12 months or less are not included in the recognized ROU assets and lease liabilities for all classes of assets. ROU assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Because the Company’s operating leases do not provide an implicit interest rate, the Company uses its incremental borrowing rate based on information available at commencement date to determine the present value of lease payments. The ROU asset also consists of any prepaid lease payments, lease incentives, or initial direct costs. The lease terms used to calculate the ROU asset and related lease liability include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for operating leases is recognized on a straight-line basis over the lease term as an operating expense while the expense for finance leases is recognized as depreciation expense and interest expense. The Company has lease agreements which require payments for lease and non-lease components (e.g. common area maintenance and equipment maintenance) that are accounted for as a single lease component. Variable lease payment amounts that cannot be determined at the commencement of the lease, such as maintenance costs based on future obligations, are not included in the ROU assets or liabilities. These are expensed as incurred and recorded as variable lease expense.
Financing Obligations	Financing Obligations Financing obligations include liabilities for the purchase of software licenses. Prior to the adoption of ASC 842, in its build-to-suit lease arrangements where the Company is involved in the construction of its buildings, the Company is deemed the owner for accounting purposes during the construction period. The Company records an asset for the amount of the total project costs in Property and Equipment, net and the related financing obligation in Lease Liabilities and Financing obligations on the Consolidated Balance Sheet. Once construction is complete, the Company determines if the asset qualifies for sale-leaseback accounting treatment. If the arrangement does not qualify for sale-lease back treatment, the Company continues to reduce the obligation over the lease term as payments are made and depreciates the asset over its useful life. The Company does not report rent expense for the portion of the rent payment determined to be related to the assets that it owns for accounting purposes. Rather, this portion of the rent payment under the lease is recognized as a reduction of the financing obligation and as interest expense.
Advertising	Advertising The Company expenses advertising costs as they are incurred. Direct advertising costs for the years ended December 31, 2019, 2018 and 2017 were $332, $391 and $168, respectively.
Comprehensive Loss	Comprehensive Loss The Company’s net loss equals comprehensive loss for all periods presented.
Stock-Based Employee Compensation	Stock-Based Employee Compensation Stock-based employee compensation is measured based on the grant-date fair value of the awards and recognized in the Consolidated Statements of Operations and Comprehensive Loss over the period during which the award holder is required to perform services in exchange for the award, which is the vesting period. Compensation expense is recognized over the vesting period of the applicable award using the straight-line method. Compensation expense related to performance-based restricted stock units, which are accounted for as equity awards, is recognized when it is probable that the performance measure will be met. Compensation costs related to restricted stock units (“RSUs”) is based on the market price on the grant date. The Company uses the Black-Scholes option pricing model for estimating the fair value of stock options. The use of the option valuation model requires the input of subjective assumptions, including the expected life of the option and the expected stock price volatility. The Company recognizes the effect of forfeitures as they occur. The recognition of stock-based compensation expense associated with performance-based restricted stock units requires the estimation of the probability of achieving performance measures. The Company adopted the guidance in Accounting Standards Update ("ASU") 2016-09, “Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting,” on January 1, 2017. Under this ASU, entities are permitted to make an accounting policy election to either estimate forfeitures on share-based payment awards, as previously required, or to recognize forfeitures as they occur. The Company has elected to recognize forfeitures as they occur and the impact of that change in accounting policy has been recorded as a $391 cumulative effect adjustment to its accumulated deficit as of January 1, 2017.
Income Taxes	Income Taxes The Company uses the asset and liability method for income tax accounting. This method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using the tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. Valuation allowances are recorded to reduce deferred tax assets to the amount the Company believes is more likely than not to be realized. The tax benefits of uncertain tax positions are recognized only when the Company believes it is more likely than not that the tax position will be upheld on examination by the taxing authorities based on the merits of the position. The Company recognizes interest and penalties, if any, related to unrecognized income tax benefits in income tax expense. Income tax effects related to settlements of share-based payment awards are reported in earnings as an increase or decrease to income tax expense (benefit), net. Additionally, income tax-related cash flows resulting from share-based payments are reported as operating activities in the statement of cash flows.
Basic and Diluted Net Loss per Common Share	Basic and Diluted Net Loss per Common Share Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share is computed by giving effect to all potential shares of common stock, including outstanding stock options, outstanding warrants, common stock related to unvested restricted stock units and convertible senior notes to the extent dilutive, and common stock issuable pursuant to the ESPP. Basic and diluted net loss per share was the same for each period presented, as the inclusion of all potential common shares outstanding would have been anti-dilutive.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards Leases On January 1, 2019, the Company adopted Accounting Standards Update (“ASU”) No. 2016-02, “Leases (Topic 842),” codified as ASC 842. 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. ASC 842 introduces new disclosure requirements for leasing arrangements. The Company adopted this update using the modified retrospective transition method at the beginning of the period of adoption. Accordingly, the Company did not adjust prior period financial statements, and recognized a cumulative-effect adjustment to the opening balance of accumulated deficit in 2019 in the amount of $7,686. The Company utilized the following additional significant policy elections: • Elected the package of three transition practical expedients to not reassess: o whether any expired or existing contracts are or contain a lease; o the classification of any expired or existing leases; and o the treatment of initial direct costs. • Adopted a policy to not separate lease and associated nonlease components for all classes of assets. The Company applied this policy to all existing leases on transition as well as new leases going forward. • Adopted a policy to not include leases with a term of 12 months or less in the recognized ROU assets and lease liabilities for all classes of assets. The adoption of this standard had a significant impact on the Company’s consolidated financial statements as follows: • Net assets of $21,019 and related financing obligations and other noncurrent liabilities of $34,909 for existing build-to-suit lease arrangements were derecognized. These leases were transitioned to the new standard based on an analysis of the lease balances as of the transition date as if they had been leases under ASC 840. Based on this analysis, the land component of these leases was combined with the remainder of the lease obligations. Historically, these obligations were accounted for separately and recognized as part of facilities expense and allocated to cost of revenue and operating expenses. Amounts recognized included $56,422 of net ROU assets, $2,848 of net leasehold improvements, and $63,952 of total finance lease liabilities. The net cumulative adjustment to accumulated deficit to derecognize and transition these leases was $7,686. • Finance lease liabilities and ROU assets of $3,589 were recorded related to payment obligations for nonlease components (e.g. common area maintenance and equipment maintenance) associated with existing capital leases. • Operating lease liabilities and ROU assets of $1,169 were recorded related to existing operating lease obligations.
Accounting Standards Not Yet Adopted	Accounting Standards Not Yet Adopted In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement.” The ASU modifies the disclosure requirements required for fair value measurements. This ASU is effective for the Company for the interim and annual reporting periods starting January 1, 2020. Early adoption is permitted. The Company does not expect this guidance to have a material impact on its consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The purpose of this ASU is to require a financial asset measured at amortized cost basis to be presented at the net amount expected to be collected. Credit losses relating to available-for-sale debt securities should be recorded through an allowance for credit losses. This ASU is effective for interim and annual reporting periods starting January 1, 2020. The Company expects its net accounts receivable balance to be affected by the adoption of this guidance but has not completed its quantifying of the impact on its consolidated financial statements.

The Company expected all of the contingent consideration would be distributed to Connecture within one year of acquisition.
