Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements and footnotes have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”). Principles of Consolidation The consolidated financial statements include the accounts of Telaria, Inc. and its wholly-owned subsidiaries. All significant inter-company transactions and balances have been eliminated in consolidation. The operating results of TVN have been included in the consolidated financial statements since the date of acquisition on August 3, 2015. Use of Estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions. The Company’s management believes that the estimates, judgments and assumptions used are reasonable based upon information available at the time they are made. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. On an ongoing basis, the Company’s management evaluates estimates, including those related to fair values and useful lives of intangible assets, fair values of stock-based awards, income taxes, and contingent liabilities. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Concentrations of Credit Risk Financial instruments that subject the Company to significant concentrations of credit risk consist primarily of cash and 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 Company’s cash and cash equivalents may exceed federally insured limits at times. The Company has not experienced any losses on cash and cash equivalents to date. The Company determines collectability of its accounts receivable by performing ongoing credit evaluations and monitoring its customers’ accounts receivable balances. For new customers and their agents, which may be advertising agencies or other third-parties, the Company performs a credit check with an independent credit agency and may check credit references to determine creditworthiness. The Company only recognizes revenue when, among other factors, collection is reasonably assured. During the years ended December 31, 2017 and 2016 there were no publishers that accounted for more than 10% of revenue, and one publisher that accounted for 11.5% of revenue for the year ended December 31, 2015 . At December 31, 2017 there were three DSPs that accounted for more than 10% of accounts receivable, which in total is 48.4% of outstanding accounts receivable. At December 31, 2016 , there was two DSP that accounted for more than 38.2% of outstanding accounts receivables. Cash and Cash Equivalents The Company considers cash deposits and all highly liquid investments with an original maturity of three months or less to be cash equivalents. The fair value of the Company’s cash and cash equivalents approximates their cost plus accrued interest because of the short-term nature of the instruments. Fair Value of Financial Instruments The Company utilizes fair value measurements when required. The carrying amounts of cash and cash equivalents, accounts receivable, prepaid expenses and other current assets, restricted cash, accounts payable and accrued expenses approximate fair values as of December 31, 2017 and 2016 due to the short-term nature of those instruments. Restricted Cash At December 31, 2017 and 2016 , the Company had total restricted cash outstanding of $0 and $770 , respectively, which was used to collateralize standby letters of credit for its former headquarters in New York, New York. In 2016, the restricted cash was used to collateralize standby letters of credit for the Company's former headquarters in New York, New York and additional space in Mountain View, California. In 2017, the standby letters of credit were collateralized by offering the available credit facility with Silicon Valley Bank. Accounts Receivable, Net The Company extends credit to customers and generally does not require any security or collateral. Accounts receivable are recorded at the invoiced amount. The Company carries its accounts receivable balances at net realizable value. Management evaluates the collectability of its accounts receivable balances on a periodic basis and determines whether to provide an allowance or if any accounts should be written down and charged to expense as bad debt. The evaluation is based on a past history of collections, current credit conditions, the length of time the account is past due and a past history of write-downs. An accounts receivable balance is considered past due if the Company has not received payments based on agreed-upon terms. The following table presents the changes in the allowance for doubtful accounts: Years Ended December 31, 2017 2016 2015 Allowance for doubtful accounts: Beginning balance $ — $ — $ — Less: write-offs and other adjustments 359 — — Ending balance $ 359 $ — $ — Property and Equipment, Net Property and equipment are stated at cost, less accumulated depreciation. Depreciation expense on property and equipment is calculated using the straight-line method over the following estimated useful lives: Computer hardware 3 years Furniture and fixtures 7 years Computer software 3 years Office equipment 3 years Leasehold improvements are amortized over the shorter of the remaining life of the lease or the life of the asset. The cost of additions and expenditures that extend the useful lives of existing assets, are capitalized, while repairs and maintenance costs are charged to operations as incurred. Impairment of Long-Lived Assets The Company periodically reviews long-lived assets, which consists of its property and equipment and intangible assets, for impairment in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 360, “Accounting for the Impairment or Disposal of Long-Lived Assets,” whenever events or changes in circumstances indicate that the carrying amount of an asset is impaired or the estimated useful lives are no longer appropriate. If indicators of impairment exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the asset, an impairment loss is recorded to write the assets down to their estimated fair values. Fair value is estimated based on discounted future cash flows. The Company did not identify any impairment losses in continuing operations related to the Company's long-lived assets during the years ended December 31, 2017 , 2016 and 2015 . Goodwill and Intangible Assets, Net Goodwill represents the excess of the aggregate purchase price paid over the fair value of the net tangible and intangible assets acquired. Intangible assets that are not considered to have an indefinite useful life are amortized over their useful lives. The Company evaluates the estimated remaining useful lives of purchased intangible assets and whether events or changes in circumstances warrant a revision to the remaining period of amortization. Goodwill is not amortized, but rather is subject to an impairment test. The Company evaluates goodwill and other intangible assets with indefinite lives for impairment annually as of October 1st, 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 adopted FASB Accounting Standards Update (“ASU”) 2011-08, “Testing Goodwill for Impairment,” which gives companies the option to qualitatively assess whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. The Company operates as one operating and reporting segment and, therefore, the Company assesses goodwill for impairment annually as one singular reporting unit, using a two-step approach. The first step is to compare the fair value of the reporting unit to the carrying value of the net assets assigned to the reporting unit. If the fair value of the reporting unit is greater than the carrying value of the net assets assigned to the reporting unit, the assigned goodwill is not considered impaired. If the fair value is less than the reporting unit’s carrying value, step two is performed to measure the amount of the impairment, if any. During the year ended December 31, 2015, the Company determined that an impairment indicator was present that required us to perform an interim goodwill impairment analysis prior to October 1st for the reporting unit. This impairment indicator was a decrease in market capitalization below the carrying value of the Company’s net assets. During the three months ended September 30, 2015, the Company conducted an interim impairment test on its goodwill, based on which the Company determined that the implied fair value of goodwill was less than the reporting unit’s carrying value. As a result, the Company recorded a goodwill impairment loss of $20,890 to reduce the carrying value of goodwill to its implied fair value. Due to the sale of the Company's buyer platform, the impairment loss of $20,890 related to the buyer's platform decline in fair value is included in the Company's discontinued operations for the year ended December 31, 2015. The Company did not identify any impairment of its goodwill at December 31, 2017 and 2016 and therefore, for the years ended December 31, 2017 and 2016 , no impairment losses related to goodwill were recorded. The Company also reviews certain identifiable intangible assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of intangible assets are measured by a comparison of the carrying amount of the asset or asset group, using an income approach, to future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets are not recoverable, the impairment to be recognized, if any, is measured by the amount which the carrying amount of the assets exceeds the estimated fair value of the assets or asset group. As the Company operates as one business unit and our long-lived assets do not have identifiable cash flows that are independent of the other assets and liabilities of this business unit, the impairment testing on intangible assets is performed at the entity-level. Intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives on a straight-line method as follows: Customer relationships 5 to 10 years Deferred rent liability The Company recognizes and records rent expense related to its lease agreements, which include rent holidays, rent escalation provisions and renewal options, on a straight-line basis beginning on the commencement date over the term of the lease. The term of the lease begins on the date of possession, which is generally when the Company enters the leased premises. The Company does not assume renewal option terms in its determination of the lease term unless such renewal option is reasonably expected to be exercised upon lease inception. Any lease incentives, which may be in the form of reduced rent payments, rent holidays or landlord incentives, are considered in determining the straight-line rent expense to be recorded over the lease term. Differences between straight-line rent expense and actual rent payments are recorded as a deferred rent liability and presented as either a current or long-term liability in the consolidated balance sheets based on the term of the respective lease agreements. Revenue Recognition The Company generates revenue each time a transaction occurs on our seller platform based on a simple and transparent fee structure established with our publisher partners. The Company does not purchase and re-sell inventory from publishers and does not collect any fees directly from buyers. The Company acts as an agent on behalf of publishers and revenue is recognized net of any inventory costs that we remit to publishers, when a buyer purchases inventory from a publisher on our platform. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether we are acting as the principal or an agent in the transaction. In determining whether the Company is acting as the principal or an agent, management followed the accounting guidance for principal-agent considerations. The determination of whether the Company is acting as a principal or an agent in a transaction involves judgment and is based on an evaluation of the terms of each arrangement, none of which are considered presumptive or determinative. Revenue generated, and costs incurred, related to our seller platform are reported on a net basis as we are not the primary obligor in our seller platform transactions as: (1) the determination of whether to purchase inventory, and the price for such inventory, is generally determined by third party buyers; and (2) we do not generally take on inventory risk. Cost of Revenue The Company's cost of revenue primarily consists of third party hosting fees and licensing fees for third party data. Costs owed to third-party vendors but not yet paid are recorded in the consolidated balance sheets and included as part of accounts payable and accrued expenses. Technology and Development Expenses Technology and development costs primarily consist of salaries, incentive compensation, stock-based compensation and other personnel-related costs for development and engineering personnel. Additional expenses in this category include costs related to development, quality assurance and testing of new technology, maintenance and enhancement of the Company's existing technology and infrastructure as well as consulting, travel and other related overhead. Due to the rapid development and changes in the Company’s business and underlying technology to date, the Company has expensed development costs in the same period that those costs were incurred. Sales and Marketing Expenses Sales and marketing expenses primarily consist of salaries, incentive compensation, stock-based compensation and other personnel-related costs for our marketing and sales and sales support employees. Additional expenses in this category include marketing programs, travel and other related overhead. These costs are expensed when incurred and are included in sales and marketing expenses. Advertising costs, which are comprised of print and internet advertising, were $183 , $17 , and $0 for the years ended December 31, 2017 , 2016 and 2015 , respectively. Stock-Based Compensation Expenses The Company accounts for stock-based compensation expense under FASB ASC 718, “Compensation—Stock Compensation,” which requires the measurement and recognition of stock-based compensation expense based on estimated fair values, for all stock-based payment awards made to employees, and FASB ASC 505-50, “ Equity-Based Payments to Non-Employees ,” which requires the measurement and recognition of stock-based compensation expense based on the estimated fair value of services or goods being received, for all stock-based payment awards made to other service providers and non-employees. The Company measures its stock-based payment awards based on its estimate of the fair value of such award using an option-pricing model, for stock option awards, and the fair value of the Company’s common stock on the date of grant, for restricted stock unit awards. The value of the portion of the award that is ultimately expected to vest is recognized as an expense over the requisite service periods in the Company’s consolidated statements of operations. The Company recognizes compensation expenses for the value of its stock-based payment awards, which have graded vesting criteria based on service and market conditions, using the straight-line method, over the requisite service period of each of the awards, net of actual forfeitures. In the event of modification of the conditions on which stock-based payment awards were granted, an additional expense is recognized for any modification that increases the total fair value of the stock-based payment arrangement or is otherwise beneficial to the employee, other service provider or non-employee at the modification date. Income Taxes Income taxes represents amounts paid or payable (or received or receivable) for the current year and includes any changes in deferred taxes during the year. The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, as well as for operating loss and tax credit carry-forwards. The Company measures deferred tax assets and liabilities using enacted tax rates expected to apply to taxable income in the years in which the Company expects to recover or settle those temporary differences. The Company recognizes the effect of a change in tax rates on deferred tax assets and liabilities in the results of operations in the period that includes the enactment date. Deferred income tax expense represents the change during the period in deferred tax assets and deferred tax liabilities. The components of the deferred tax assets and liabilities are individually classified as non-current. The Company reduces the measurement of a deferred tax asset, if necessary, by a valuation allowance if it is more likely than not that the Company will not realize some or all of the deferred tax asset. As a result of the Company’s historical operating performance and the cumulative net losses incurred to date, the Company does not have sufficient objective evidence to support the recovery of the deferred tax assets. Accordingly, the Company has established a valuation allowance against substantially all of its deferred tax assets for financial reporting purposes because the Company believes it is more likely than not that these deferred tax assets will not be realized. The Company accounts for uncertain tax positions by recognizing the financial statement effects of a tax position only when, based upon technical merits, it is “more-likely-than-not” that the position will be sustained upon examination. Potential interest and penalties associated with unrecognized tax positions are recognized in its provision for income taxes in the consolidated statements of operations. Net Income (Loss) Per Share Attributable to Common Stockholders Basic net income (loss) per share attributable to common stockholders is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. Diluted net income (loss) per share attributable to common stockholders is computed by dividing net income (loss) attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period, adjusted to reflect potentially dilutive securities using the treasury stock method for warrants to purchase common stock, stock option awards and restricted stock unit awards. Due to the Company’s loss from continuing operations, net of income taxes: (i) warrants to purchase common stock; (ii) stock option awards; and (iii) restricted stock unit awards were not included in the computation of diluted net loss per share attributable to common stockholders, as the effects would be anti-dilutive. Accordingly, basic and diluted net loss per share attributable to common stockholders is equal for the years presented. Comprehensive Income (Loss) Comprehensive income (loss) consists of foreign currency translation adjustments. Total comprehensive income (loss) and its components are presented in the accompanying consolidated statements of comprehensive income (loss). Foreign Currency Translation Adjustments The functional currency of the Company’s international subsidiaries is their local currency. The Company translates the financial statements of these subsidiaries to U.S. dollars using period-end exchange rates for assets and liabilities, and average exchange rates for revenue and expenses. Translation gains and losses are recorded in accumulated other comprehensive (loss) income as a component of stockholders’ equity. During the years ended December 31, 2017 , 2016 and 2015 , foreign currency translation adjustment gain and losses of $99 , $(276) , and $(153) respectively, were recorded as a component of comprehensive income (loss) in the consolidated financial statements. Realized and unrealized transaction gains and losses are included in the consolidated statements of operations in the period in which they occur, except on inter-company balances considered to be long-term. Transaction gains and losses on inter-company balances which are considered to be long-term are recorded in accumulated other comprehensive (loss) income. The Company considers its inter-company balances to be long-term in nature. Net (losses) gain resulting from transactions denominated in foreign currencies were accounted for in the Company’s consolidated statements of operations and totaled $44 , $(21) , and $(4) during the years ended December 31, 2017 , 2016 and 2015 , respectively. Recently Issued Accounting Pronouncements FASB Accounting Standards Update No. 2017-09 - Compensation - Stock Compensation (Topic 718) In September 2017, Financial Accounting Standards Board, ("FASB") issued an Accounting Standards Update, ("ASU") No. 2017 - 09 Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. This ASU clarifies and eliminates the diversity of practice as to when a Company must account for the effects of a stock modification. In accordance with the guidance an entity should account for the effects of a modification unless all the following criteria are met: 1. The fair value of the modified award is the same as the fair value of the original award immediately before the original award is modified. If the modification does not affect any of the inputs to the valuation technique that the entity uses to value the award, the entity is not required to estimate the value immediately before and after the modification. 2. The vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified. 3. The classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The requirement is for public business entities to apply the guidance prospectively to annual reporting periods beginning after December 15, 2017 with early adoption permitted, including in the interim periods. The Company does not believe the adoption of this ASU will have a material impact prospectively, to the Company’s consolidated financial statements. FASB Accounting Standards Update No. 2017-04 - Intangibles and Other (Topic 350) In January 2017, FASB issued ASU No. 2017-04, Intangibles and Other (Topic 350): Simplifying the Test for Goodwill Impairment. The pronouncement eliminates Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities). Now the entity compares the fair value of the reporting unit with its carrying amount. The requirement is for public business entities to apply the guidance to annual reporting periods beginning after December 15, 2019. Early adoption is permitted for interim or annual impairment tests after January 1, 2017. The Company does not believe the adoption of this ASU will have a material impact prospectively, to the Company’s consolidated financial statements. FASB Accounting Standards Update No. 2017-01 - Business Combinations (Topic 805) In January 2017, FASB issued ASU No. 2017-01, “Business Combinations (Topic 805): Clarifying the Definition of a Business”. The amendment was issued to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this ASU provide a screen to determine when a set (inputs and processes that produce an output) is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. The requirement is for public business entities to apply the guidance to annual reporting periods beginning after December 15, 2017. The Company does not believe the adoption of this ASU will have a material impact prospectively, to the Company’s consolidated financial statements. FASB Accounting Standards Update No. 2016-18 - Statement of Cash Flows (Topic 230) In November 2016, FASB issued Accounting Standards Update ASU No. 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash. This update requires that a Statement of Cash Flow explain the change during the period in the total cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash should be included with cash & cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the Statement of Cash Flows. Public business entities should apply the guidance to annual reporting periods beginning after December 15, 2017 with early adoption permitted. The Company is currently evaluating the effects, if any, that adoption of this ASU will have on the Company's consolidated financial statements. FASB Accounting Standards Update No. 2016-15 — Classification of Certain Cash Receipts and Cash Payments In August 2016, the FASB issued ASU No. 2016-15, Classification of Certain Cash Receipts and Cash Payments, which clarifies how entities should classify certain cash receipts and cash payments on the statement of cash flows. The new guidance also clarifies how the predominance principle should be applied when cash receipts and cash payments have aspects of more than one class of cash flows. This update is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact that the update will have on its consolidated financial statements and related disclosures. FASB Accounting Standards Update No. 2016-09 — Compensation — Stock Compensation (Topic 718) In March 2016, the FASB issued an ASU No. 2016-09, Compensation -Stock Compensation, which identifies areas for simplification involving several aspects of accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, an option to recognize gross stock compensation expense with actual forfeitures recognized as they occur, as well as certain classifications on the statement of cash flows. This update is effective for fiscal years beginning after December 15, 2016 including interim periods within that reporting period, with early adoption permitted. The Company has adopted the provisions of ASU 2016-09 in the first quarter of 2017. The guidance requires the recognition in the income statement of the income tax effects of vested or settled awards. Further, the guidance requires that the recognition of anticipated tax windfalls/shortfalls be excluded in the calculation of assumed proceeds when applying the treasury stock method. The guidance also allows for the employer to repurchase more of an employee’s shares for tax withholding purposes and not classify the award as a liability that requires valuation on a mark-to-market basis. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. As a result of the adoption, the impact to the financial statements resulted in an increase in the accumulated deficit and a corresponding increase in additional paid-in capital of $94 during the year ended December 31, 2017. FASB Accounting Standards Update No. 2016-02 — Leases (Topic 842) In February 2016, the FASB issued ASU No. 2016-02, Leases, which clarifies and improves existing authoritative guidance related to leasing transactions. This update will require the recognition of lease assets and lease liabilities on the balance sheet and disclosing information about material leasing arrangements. This update is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the impact that the update will have on its consolidated financial statements and related disclosures. FASB Accounting Standards Update No. 2015-16 — Business Combinations (“Topic 805”): Simplifying the Accounting for Measurement-Period Adjustments In September 2015, the FASB issued ASU No. 2015-16, Business Combinations, which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Pursuant to this update, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. This guidance is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. The Company adopted this update in the first quarter of 2017 with no impact on its consolidated financial statements and related disclosures. FASB Accounting Standards Update No. 2014-09 — Revenue from Contracts with Customers In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers that provides a comprehensive model for recognizing revenue with customers. This update clarifies and replaces all existing revenue recognition guidance within U.S. GAAP and may be adopted retrospectively for all periods presented or adopted using a modified retrospective approach. In August 2015, The FASB issued ASU No. 2015-14, Revenue from Contracts with Customers, Deferral of the Effective Date, which deferred the effective date by one year to December 15, 2017 (beginning with the Company’s first quarter in 2018) and permitting early adoption of the standard, but not before the original effective date of December 15, 2016. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers, Principal vs. Agent Consideration (Reporting Gross versus Net), which clarifies the implementation guidance on principal versus agent considerations. The guidance includes indicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The Company will adopt the new standard in the first quarter of 2018 and expects to apply the modified retrospective approach. The Company has assigned internal resources in addition to the engagement of a third-party service provider to assist in evaluating the impact of the new standard on its accounting policies, processes and system requirements. The Company finalized our analysis and the adoption of this guidance will not have a material impact on our consolidated financial statements. |
