Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The Company’s accounting and financial reporting policies conform to accounting principles generally accepted in the United States of America (“GAAP”). Principles of Consolidation The accompanying consolidated financial statements include the accounts of TrueCar and its wholly owned subsidiaries. Business acquisitions are included in the Company’s consolidated financial statements from the date of the acquisition. The Company’s purchase accounting resulted in all assets and liabilities of acquired businesses being recorded at their estimated fair values on the acquisition dates. All intercompany balances and transactions have been eliminated in consolidation. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Assets and liabilities that are subject to judgment and use of estimates include sales allowances and allowances for doubtful accounts, contract assets, the fair value of a warrant asset and the related liability, the fair value of assets and liabilities assumed in business combinations, the fair value of the capitalized facility leases, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets, useful lives associated with property and equipment and intangible assets, lease exit liabilities, contingencies, and the valuation and assumptions underlying stock-based compensation and other equity instruments. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for making judgments about the carrying value of assets and liabilities. In addition, the Company engaged valuation specialists to assist with management’s determination of the fair values of its right-of-use assets and lease liabilities, capitalized facility leases, assets and liabilities assumed in business combinations, warrant asset and related liability, assets and liabilities of its equity method investment, performance-based stock units, and in periods prior to the Company’s initial public offering, valuation of common stock. Segments The Company has one operating segment. During the first quarter of 2019, the Company’s chief operating decision maker (“CODM”) was the President and Chief Executive Officer and the Interim Chief Financial Officer and Chief Accounting Officer, who managed the Company’s operations based on consolidated financial information for purposes of evaluating financial performance and allocating resources. Effective April 1, 2019, the Company’s Interim Chief Financial Officer and Chief Accounting Officer resigned from his positions. From April 1, 2019, through May 31, 2019, the Company’s CODM was solely comprised of the President and Chief Executive Officer until his resignation on May 31, 2019. From June 1, 2019 through June 16, 2019, the CODM was comprised of the Interim President and Chief Executive Officer. Upon the hiring of the Chief Financial Officer on June 17, 2019 and through December 31, 2019, the CODM was comprised of both the Interim President and Chief Executive Officer and the Chief Financial Officer. During the year ended December 31, 2019, the Company’s operations were managed based on consolidated financial information for purposes of evaluating financial performance and allocating resources by the various CODM in place. The CODM reviews financial information on a consolidated basis, accompanied by information about dealer revenue, OEM incentive revenue, and forecasts, consulting and other revenue (Note 4). All of the Company’s principal operations, decision-making functions and assets are located in the United States. Equity Method Investment On February 8, 2019, the Company acquired 20% of the outstanding equity interests of Accu-Trade, LLC, a Delaware limited liability company (“Accu-Trade”), from R.M. Hollenshead Auto Sales & Leasing, Inc., a Florida corporation (“RHAS”), Robert M. Hollenshead (“Hollenshead”) and Jeffrey J. Zamora (“Zamora” and, together with RHAS and Hollenshead, the “Sellers”), pursuant to a Membership Interest Purchase Agreement, dated as of February 8, 2019 (the “Purchase Agreement”), by and among Accu-Trade, RHAS, Hollenshead, Zamora and the Company. Pursuant to the Purchase Agreement, and upon the terms and subject to the conditions thereof, the Company paid the Sellers $17.9 million in cash consideration and made a $5 million capital contribution to Accu-Trade. The Company recognizes its proportional share of the income or loss from the equity method investment on a one-quarter lag due to the timing and availability of financial information from Accu-Trade. Included in the initial carrying value of $22.9 million , which represents the fair value on the transaction date, was a basis difference of $21.0 million related to the difference between the cost of the investment and the Company’s proportionate share of the net assets of Accu-Trade. The carrying value of the equity method investment is primarily adjusted for the Company’s share in the losses of Accu-Trade and amortization of the basis difference. The Company amortizes its basis difference between the estimated fair value and the underlying book value of Accu-Trade’s technology and guarantor relationship over their respective useful lives using the straight-line method. The weighted-average life of these intangible assets is approximately 5 years . Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Accounting standards describe a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: • Level 1 — Quoted prices in active markets for identical assets or liabilities or funds. • Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Fair Value Methods Fair value is based on quoted market prices, if available. If listed prices or quotes are not available, fair value is based on internally-developed models that primarily use market-based or independently sourced market parameters as inputs. For assets and liabilities measured at fair value, the following section describes the valuation methodologies, key inputs, and significant assumptions. Cash equivalents, consisting primarily of money market instruments and debt securities, represent highly liquid investments with maturities of three months or less at purchase. Generally, market prices are used to determine the fair value of money market instruments and debt securities. The carrying amounts of cash equivalents, accounts receivable, prepaid and other current assets, accounts payable, and accrued liabilities approximate fair value because of the short maturity of these items. The fair value of the Company’s revolving line of credit approximates carrying value based on the Company’s current incremental borrowing rate for similar types of borrowing arrangements. Certain assets, including the equity method investment, warrant asset, right-of-use assets, property and equipment, goodwill, and intangible assets are also subject to measurement at fair value on a non-recurring basis if they are deemed to be impaired as a result of an impairment review. For the years ended December 31, 2019 , 2018 , and 2017 , no impairments were identified on those assets required to be measured at fair value on a non-recurring basis. The Company recorded a contingent consideration liability upon the acquisition of DealerScience in 2018 (Note 5). Contingent consideration is measured at fair value and is based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair-value hierarchy. The valuation of contingent consideration uses assumptions the Company believes a market participant would make. The Company assesses these estimates on an ongoing basis as it obtains additional data impacting the assumptions. Changes in the fair value of contingent consideration related to updated assumptions and estimates are recognized within the consolidated statements of comprehensive loss. The Company determined the fair value of the contingent consideration using the probability-adjusted discounted cash flow method. Because the DealerScience purchase agreement makes payment of the contingent consideration contingent on achievement of certain revenue milestones, the significant unobservable inputs used in the fair value measurement of contingent consideration are the probabilities of achieving those milestones and discount rates. Significant increases or decreases in the probabilities of achieving the milestones would result in a significantly higher or lower fair value measurement, respectively. The following table summarizes the Company’s assets and liabilities at fair value on a recurring basis at December 31, 2019 and 2018 by level within the fair-value hierarchy. These assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement (in thousands): At December 31, 2019 At December 31, 2018 Total Fair Total Fair Level 1 Level 2 Level 3 Value Level 1 Level 2 Level 3 Value Assets: Cash equivalents $ 174,429 $ — $ — $ 174,429 $ 192,207 $ — $ — $ 192,207 Total Assets $ 174,429 $ — $ — $ 174,429 $ 192,207 $ — $ — $ 192,207 Liabilities: Contingent consideration, current $ — $ — $ 2,441 $ 2,441 $ — $ — $ — $ — Contingent consideration, non-current — — 2,336 2,336 — — 4,477 4,477 Total Liabilities $ — $ — $ 4,777 $ 4,777 $ — $ — $ 4,477 $ 4,477 Contingent Consideration Obligations The following table summarizes the changes in the fair value of the contingent consideration obligation (in thousands): Year Ended December 31, 2019 2018 Fair value, at beginning of year $ 4,477 $ — Additions — 4,477 Changes in fair value 300 — Fair value, at end of year $ 4,777 $ 4,477 Concentrations of Credit and Business Risk Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents and accounts receivable. The Company, at times, maintains cash balances at financial institutions in excess of amounts insured by United States government agencies or payable by the United States government directly. The Company places its cash and cash equivalents with high credit quality financial institutions. Credit is extended to customers based on an evaluation of their financial condition and other factors. The Company generally does not require collateral or other security to support accounts receivable. The Company performs ongoing credit evaluations of its customers and maintains an allowance for doubtful accounts based on these evaluations. No single customer comprised more than 10% of the Company’s total revenues for the years ended December 31, 2019 , 2018 , and 2017 . No single customer comprised more than 10% of the Company’s accounts receivable balance at December 31, 2019 and 2018 . The Company’s largest source of unique visitors and unit sales from affinity group marketing partners in 2019 comes from its relationship with United Services Automobile Association (“USAA”), a related party (Note 15). See Note 16 for further details on a short-term agreement executed subsequent to December 31, 2019. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original or remaining maturity at the date of purchase of three months or less to be cash equivalents. At December 31, 2019 and 2018 , cash and cash equivalents were comprised of cash held in money market funds and checking accounts. Accounts Receivable, Allowance for Doubtful Accounts, and Sales Allowances The Company extends credit in the normal course of business to its customers and performs credit evaluations on a case-by-case basis. The Company does not obtain collateral or other security related to its accounts receivable. Accounts receivable are recorded based on the amount due from the customer and do not bear interest. The Company reduces accounts receivable for sales allowances and its allowance for doubtful accounts. For contract assets, the Company records the assets net of sales allowances and an allowance for doubtful accounts, which are estimated in the same manner as for accounts receivable balances. The Company establishes sales allowances at the time of revenue recognition based on its history of adjustments and credits provided to its network of dealers. Sales allowances relate primarily to credits issued where a dealer claims that an introduction was previously identified by the dealer from a source other than the Company. While the dealer is contractually obligated to pay the invoice, the Company may issue a credit against the invoice to maintain overall dealer relations. In assessing the adequacy of its sales allowances, the Company evaluates its history of adjustments and credits made through the date of the issuance of the financial statements. Estimated sales adjustments and credits and ultimate losses may vary from actual results which could be material to the financial statements; however, to date, actual sales allowances have been materially consistent with the Company’s estimates. The Company determines its allowance for doubtful accounts based on its historical write-off experience and specific circumstances that make it likely that recovery will not occur in a particular case. The Company reviews the allowance for doubtful accounts each reporting period and assesses the aging of account balances, with an emphasis on those that are past due over ninety days . Account balances are charged off against the allowance when the Company determines that it is probable the receivable will not be recovered. The Company does not have any off-balance sheet credit exposure related to its customers. The following table summarizes the changes in the allowance for doubtful accounts and sales allowances (in thousands): Year Ended December 31, 2019 2018 2017 Allowances, at beginning of year $ 3,382 $ 3,030 $ 2,600 Charged as a reduction of revenue 11,751 8,703 7,734 Charged to bad debt expense in general and administrative expenses 1,432 1,688 1,385 Write-offs, net of recoveries (9,806 ) (10,039 ) (8,689 ) Allowances, at end of year $ 6,759 $ 3,382 $ 3,030 Property and Equipment, net Property and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, which is generally three years for computer hardware and software, five years for furniture and equipment, and over the shorter of the lease term or the useful life of the assets for leasehold improvements. Maintenance and repairs are expensed as incurred. When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or loss is reflected in the Company’s results of operations. Leases On January 1, 2019, the Company adopted the new lease accounting standard using the modified retrospective transition method applied at the effective date of the standard. The Company determines if an arrangement is a lease at inception and determine the classification of the lease, as either operating or finance, at commencement. The Company does not have any finance leases. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The Company estimates the incremental borrowing rate to reflect the profile of secured borrowing over the expected term of the leases based on the information available at the later of the initial date of adoption or the lease commencement date. The operating lease ROU asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Sublease rental income is recognized as a reduction to the related lease expense on a straight-line basis over the sublease term. See Note 3 for additional information. Software and Website Development Costs The Company accounts for the costs of computer software obtained or developed for internal use in accordance with FASB ASC 350, Intangibles — Goodwill and Other . Computer software development costs and website development costs are expensed as incurred, except for internal use software or website development costs that qualify for capitalization as described below, and include certain employee related expenses, including salaries, bonuses, benefits and stock-based compensation expenses; costs of computer hardware and software; and costs incurred in developing features and functionality. These capitalized costs are included in property and equipment on the consolidated balance sheets. The Company expenses costs incurred in the preliminary project and post-implementation stages of software development and capitalizes costs incurred in the application development stage and costs associated with significant enhancements to existing internal use software applications. Software costs are amortized using the straight-line method over an estimated useful life of three years commencing when the software project is ready for its intended use. Costs incurred related to less significant modifications and enhancements as well as maintenance are expensed as incurred. At December 31, 2019 and 2018 , capitalized software costs were $50.4 million and $86.0 million , respectively, before accumulated amortization of $28.2 million and $62.2 million , respectively. During the years ended December 31, 2019 and 2018 , the Company recorded accelerated amortization of $1.1 million and $1.0 million , respectively, related to software assets that were determined to have shortened useful lives due to upgrades to the Company’s technology infrastructure. Expected amortization expense with respect to capitalized software costs at December 31, 2019 for each of the years through December 31, 2022 is as follows (in thousands): Years ended December 31, 2020 $ 12,302 2021 7,504 2022 2,364 Total amortization expense $ 22,170 Intangible Assets Acquired in Business Combinations The Company values assets acquired and liabilities assumed on each acquisition accounted for as a business combination, and allocates the purchase price to the tangible and intangible assets acquired and liabilities assumed based on its best estimate of fair value. Acquired intangible assets include: trade names, customer relationships, and developed technology. The Company determines the appropriate useful life of intangible assets by performing an analysis of cash flows based on historical experience of the acquired businesses. Intangible assets are amortized over their estimated useful lives based on the pattern in which the economic benefits associated with the asset are expected to be consumed, which to date has approximated the straight-line method of amortization. The estimated useful lives for trade names, customer relationships, and technology are generally, one to fifteen years , two to ten years , and three to ten years , respectively. Long-Lived Assets The Company evaluates the recoverability of its long-lived assets with finite useful lives for impairment whenever events or changes in circumstances indicate that the carrying amounts may not be recoverable. Such triggering events or changes in circumstances may include: a significant decrease in the market price of a long-lived asset, a significant adverse change in the extent or manner in which a long-lived asset is being used, a significant adverse change in legal factors or in the business climate, the impact of competition or other factors that could affect the value of a long-lived asset, a significant deterioration in the amount of revenue or cash flows expected to be generated from an asset group, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of a long-lived asset, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset, or a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously-estimated useful life. The Company performs impairment testing at the asset group level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If events or changes in circumstances indicate that the carrying amount of an asset group may not be recoverable and the expected undiscounted future cash flows attributable to the asset group are less than the carrying amount of the asset group, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Fair value is determined based upon estimated discounted future cash flows. During the years ended December 31, 2019 , 2018 , and 2017 , there were no impairment charges recorded on the Company’s long-lived assets. Goodwill Goodwill represents the excess of the aggregate purchase price paid over the fair value of the identifiable assets and liabilities acquired in the Company’s business combinations. Goodwill is not amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Events or changes in circumstances that could trigger an impairment review include a significant adverse change in business climate, an adverse action or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of use of the acquired assets or the Company’s overall business strategy, significant negative industry or economic trends, significant underperformance relative to expected historical or projected future results of operations, or a decline in the Company’s stock price and market capitalization. During 2019, the Company’s stock price experienced high volatility ranging from a high of $10.39 to a low of $3.01 per share, causing a decline in its enterprise market capitalization. If the Company’s stock price declines further, material write-downs or impairment charges may be required in the future. The magnitude and timing of those charges would be dependent on the severity and duration of the decline and cannot be determined at this time. Any material non-cash impairment charges related to goodwill would have a material adverse effect on the Company’s results of operations and financial condition. The Company has the option to assess goodwill for possible impairment by performing a qualitative analysis to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount or to perform the quantitative impairment test. The quantitative test involves comparing the estimated fair value of a reporting unit with its respective book value, including goodwill. If the estimated fair value exceeds book value, goodwill is considered not to be impaired. If, however, the fair value of the reporting unit is less than book value, an impairment loss is recognized in an amount equal to the excess. The Company tests for goodwill impairment annually at December 31st. During the years ended December 31, 2019 , 2018 , and 2017 , there were no impairment charges recorded on goodwill. In 2019 and 2018, we elected to conduct a quantitative goodwill assessment at December 31, 2019 and 2018 , respectively. The fair value significantly exceeded the carrying value and, accordingly, we concluded that there was no impairment of goodwill at December 31, 2019 and 2018 . During the year ended December 31, 2018, goodwill increased $20.0 million as a result of the DealerScience acquisition. See Note 5 for further details. Warrant On November 19, 2018, TrueCar entered into a warrant agreement with DealerSync, Inc. (“DealerSync”) that entitles TrueCar to purchase up to 2,500,000 shares of DealerSync common stock at $1.60 per share. The warrant expires on November 19, 2020. The fair value was determined using a Monte-Carlo simulation. The Company recorded the fair value of the DealerSync warrant of $1.2 million in “other assets” and corresponding liabilities (the current portion of the liability of $0.2 million recorded in “accrued expenses and other current liabilities” and the non-current portion of $1.0 million recorded in “other liabilities”) in the consolidated balance sheet as of December 31, 2018, reflecting the benefit received as part of its commercial sales agent agreement with DealerSync. In June 2019, the Company terminated its commercial sales agent agreement with DealerSync, resulting in the write-off of the warrant asset and corresponding liability. The net impact of the write-offs was immaterial to the Company’s consolidated statements of comprehensive loss during the year ended December 31, 2019. Revenue Recognition In May 2014, the FASB issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard replaces all existing revenue recognition guidance under GAAP. The Company adopted the new revenue standard as of January 1, 2018 using the modified retrospective transition method. Results for reporting periods beginning after January 1, 2018 are presented under the new revenue standard, while prior period amounts are not adjusted and continue to be reported in accordance with prior revenue guidance. See Note 4 for further details. Under the new revenue standard, the Company recognizes revenue when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration it expects to be entitled to in exchange for those goods or services. The Company determines revenue recognition through the following steps: • Identification of the contract, or contracts, 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, the performance obligation or obligations are satisfied. Dealer Revenue Dealer revenue is comprised of Auto Buying Program revenue as well as revenue from TrueCar Trade and DealerScience. Auto Buying Program revenues include fees paid by customers participating in the Company’s dealer network with which the Company has an agreement (“TrueCar Certified Dealers” or “Dealers”). TrueCar Certified Dealers pay the Company fees in one of three ways: on a per-vehicle basis for sales to Auto Buying Program users, on a per-introduction basis for sales to Auto Buying Program users, or under a subscription arrangement. Contracts are cancellable by the Dealer or the Company at any time. The Company does not provide significant Dealer financing terms. The Company’s performance obligation to TrueCar Certified Dealers is the same for all payment types for our Auto Buying Program revenues: to provide Dealers with introductions to in-market consumers through the use of the TrueCar platform, so that those Dealers have the opportunity to sell vehicles to those consumers. Control transfers to Dealers upon delivery of introductions, which is the point at which the Company recognizes revenue. When a user decides to proceed with a vehicle purchase through the Company, the user provides his or her name, address, email, and phone number during the process of obtaining price offers on actual vehicle inventory, which gives the Company the identity and source of a TrueCar introduction provided to a specific Dealer before an actual sale occurs. After a sale occurs, the Company receives information regarding the sale, including the identity of the purchaser, through the Dealer Management System used by the Dealer that made the sale. The Company also receives information regarding vehicle sales from a variety of other data sources, including third-party car sales aggregators, car dealer networks, and other publicly available sources (collectively, “sales data”) and uses this sales data to further verify that a sale has occurred between an Auto Buying Program user and a TrueCar Certified Dealer, as well as to invoice the Dealer shortly after the completion of the sales transaction. Actual vehicle sales data is reported on a daily basis shortly following the date of sale. Pay-Per-Sale. Under the old revenue standard, in years prior to 2018, the Company recognized revenue for fee arrangements based on a per-vehicle basis when the vehicle sale had occurred between the Auto Buying Program user and the Dealer. Under the new revenue standard for fee arrangements based on a pay-per-sale billing model, revenue for the Auto Buying Program is recognized when introductions are delivered to the Dealer and for the amount that the Company estimates it will be able to earn. To formulate this estimate, the Company uses the expected value method based primarily on an analysis of the expected number of sales resulting from in-period introductions. This estimate is based on historical introductions to vehicle sale close rate trends as well as actual sales measured in period. Under the contractual terms and conditions of arrangements with TrueCar Certified Dealers that pay on a per-vehicle-sale basis, the Dealer is not obligated to pay the Company until a vehicle sale has occurred between the Auto Buying Program user and the Dealer, for which the introduction was provided to the Dealer by the Company. Contractually, the Dealers’ obligation to pay is not contingent on verification or acceptance of the transaction by the Dealer. As a result, revenue recognition occurs earlier than billing as an estimate of the variable consideration to be received upon control transfer of the delivered introduction, resulting in a contract asset. Pay-Per-Introduction. Under fee arrangements based on a pay-per-introduction billing model, revenue for the Auto Buying Program is recognized when introductions are delivered. The Company also recognizes revenue from Dealers under subscription agreements. Subscription fee arrangements are short-term in nature with terms ranging from one to six months and are also cancellable by the Dealer or the Company at any time. Subscription arrangements fall into three types: flat-rate subscriptions, subscriptions subject to downward adjustment based on a minimum number of vehicle sales (“guaranteed sales”), and subscriptions based on introduction volume, including those subject to downward adjustment based on a minimum number of introductions (“guaranteed introductions”). For all subscription arra |
