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 intercompany transactions and balances have been eliminated in the accompanying consolidated financial statements. The operating results of SlimCut and TVN have been included in the consolidated financial statements since their dates of acquisition on June 8, 2018 and August 3, 2015, respectively. Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation with no impact on consolidated net income(loss) or cash flows. 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 customer 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, 2018 , and 2017 there was one publisher that accounted for more than 10% of revenue. At December 31, 2018 there was one DSPs that accounted for 32.0% of accounts receivable. At December 31, 2017 , there were three DSPs that together accounted for 48.4% 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, accounts payable and accrued expenses approximate fair values as of December 31, 2018 and 2017 due to the short-term nature of those instruments. 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, 2018 2017 2016 Allowance for doubtful accounts: Beginning balance $ 359 $ — $ — Add: Reserves 1,052 — — Less: Write-offs (429 ) 359 — Ending balance $ 982 $ 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. 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, 2018 , 2017 and 2016 . 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 operates as one operating and reporting segment and therefore, evaluates goodwill and other intangible assets with indefinite lives for impairment impairment annually as one singular reporting unit, on October 1 or more frequently when an event occurs or circumstances change that indicates the carrying value may not be recoverable. The Company has the option to assess goodwill for impairment by first performing 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 amount. If the Company determines that it is not more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, then the two-step goodwill impairment test is not required to be performed. If the Company determines that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying amount, or if the Company does not elect the option to perform an initial qualitative assessment, the Company performs the two-step goodwill impairment test. In the first step, the fair value of the reporting unit is compared to its book value including goodwill. If the fair value of the reporting unit is in excess of its book value, the related goodwill is not impaired and no further analysis is necessary. If the fair value of the reporting unit is less than its book value, there is an indication of potential impairment and a second step is performed. When required, the second step of testing involves calculating the implied fair value of goodwill for the reporting unit. The implied fair value of goodwill is determined in the same manner as goodwill recognized in a business combination, which is the excess of the fair value of the reporting unit determined in step one over the fair value of its net assets, including identifiable intangible assets, as if the reporting unit had been acquired. If the carrying value of the reporting unit's goodwill exceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess. The Company did not identify any impairment of its goodwill at December 31, 2018 , 2017 and 2016 and therefore, for the years ended December 31, 2018 , 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: Technology 5 years Customer relationships 6 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 primarily generates revenue on a transactional basis where it is paid by a publisher each time an advertising impression is monetized on its platform based on a simple and transparent fee structure that the Company establishes with its publisher partners. For substantially all such transactions, the Company acts as an agent on behalf of publishers and revenue is recognized net of any inventory costs that the Company remits to publishers, when a buyer purchases inventory from a publisher on the Company's platform. The determination of whether revenue should be reported on a gross or net basis is based on an assessment of whether the Company is acting as the principal or an agent in the transaction. In determining whether the Company is acting as the principal or an agent, the Company 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. Substantially all of the revenue generated, and costs incurred, related to publisher transactions on the Company's platform reported on a net basis as the Company determined that it acts as an agent for publishers and is not the primary obligor in such transactions, given that: (1) another party is primarily responsible for fulfilling the contract and the Company does not have discretion in establishing prices and (2) the Company does not generally take on inventory risk. For certain transactions, the Company reports revenue on a gross basis, based primarily on its determination that the Company acts as the primary obligor in the delivery of advertising campaigns for buyers with respect to such transactions. Cost of Revenue The Company's cost of revenue primarily consists of third party hosting fees, licensing fees and cost of inventory for third party data and certain publisher costs which we record on a gross basis. 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 $75 , $183 and $17 for the years ended December 31, 2018 , 2017 and 2016, 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. On December 22, 2017, the U.S. President signed the Tax Cuts and Jobs Act (the “Act”) into law. Effective January 1, 2018, among other changes, the Act (1) reduces the U.S. federal corporate tax rate from 35 percent to 21 percent, (2) changes the rules relating to net operating loss ("NOL") carryforwards and carrybacks, (3) eliminates the corporate alternative minimum tax ("AMT") and changes how existing AMT credits can be realized; and (4) requires companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries. Given the significance of the legislation, the U.S. Securities and Exchange Commission (the "SEC") staff issued Staff Accounting Bulletin No.118 ("SAB 118"), which allows registrants to record provisional amounts during a one-year "measurement period". During the measurement period, impacts of the law are expected to be recorded at the time a reasonable estimate for all or a portion of the effects can be made, and provisional amounts can be recognized and adjusted as information becomes available, prepared, or analyzed. As of December 31, 2018, we have not recorded incremental accounting adjustments related to the Act as we continue to consider interpretations of its application. The Tax Act did not have a material impact on our financial statements since our deferred temporary differences in the United States are fully offset by a valuation allowance and we do not have any significant off shore earnings from which to record the mandatory transition tax. We did not record any provision for federal income taxes for the period ended December 31, 2018. 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 the purchase of the Company's common stock, stock option awards and restricted stock unit awards. Due to the Company’s loss from continuing operations, net of income taxes: (i) stock option awards; and (ii) 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 component is 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, 2018 , 2017 and 2016 , foreign currency translation adjustment gain and losses of $(717) , $99 , and $(276) respectively, were recorded as a component of comprehensive income (loss) in the consolidated financial statements. Net (losses) gain resulting from transactions denominated in foreign currencies were accounted for in the Company’s consolidated statements of operations and totaled $4 , $44 , and $(21) during the years ended December 31, 2018 , 2017 and 2016 , respectively. Recently Issued Accounting Pronouncements FASB Accounting Standards Update No. 2018-15 - Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) In August 2018, Financial Accounting Standards Board, ("FASB") issued an Accounting Standards Update, ("ASU") No. 2018-15 Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract. The amendments in this update align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The requirement is for public business entities to apply the guidance to annual reporting periods beginning after December 15, 2019 with early adoption permitted, including interim periods. The Company does not believe the adoption of this amendment will have a material impact prospectively to the Company's consolidated financial statements and related disclosures. FASB Accounting Standards Update No. 2018-13 - Fair Value Measurement (Topic 820) In August 2018, FASB issued ASU No. 2018-13 Fair Value Measurements (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in the update modify the disclosure requirements on fair value measurements in Topic 820, including the removal, modification and additions of certain disclosure requirements for Level 3 fair value measurements and for transfers between Level 1 and Level 2 of the fair value hierarchy. The requirement is for all entities that are required to make disclosures about recurring or nonrecurring fair value measurements to apply the guidance to annual reporting periods beginning after December 15, 2019 with early adoption permitted for any modified or removed disclosures only. The Company does not believe adoption of this amendment will have a material impact prospectively to the Company's consolidated financial statements and related disclosures. FASB Accounting Standards Update No. 2018-07 - Improvements to Nonemployee Share-Based Payment Accounting (Topic 718) In June 2018, FASB issued an ASU No. 2018-07 Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. The amendment simplifies the accounting for equity based payments to nonemployees by expanding the scope of Topic 718 to include nonemployees. The requirement is for public business entities to apply the guidance to annual reporting periods beginning after December 15, 2018 with early adoption permitted, including interim periods. The Company does not believe adoption of this amendment will have a material impact prospectively to the Company's consolidated financial statements and related disclosures. FASB Accounting Standards Update No. 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220) In February 2018, FASB issued an ASU No. 2018-02 Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The amendments in this update allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. The requirement is for public business entities to apply the guidance to annual reporting periods beginning after December 15, 2018 with early adoption permitted, including the interim periods. The Company is currently evaluating the impact the update will have on its consolidated financial statements and related disclosures. 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 adopted this update in the first quarter of 2018 on a prospective basis. The adoption of this update did not have a material impact on the Company’s consolidated financial statements and related disclosures. 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. This ASU eliminates Step 2 of the goodwill impairment test and requires a goodwill impairment to be measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of its goodwill. The ASU is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company adopted this ASU during the third quarter of 2018 and did not have a material impact on its 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 adopted this update on a prospective basis in the first quarter of 2018 with no material impact to the Company's consolidated financial statements and related disclosures. 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 adopted this update in the first quarter of 2018 and included restricted cash in cash and cash equivalents in the Company's 2018 consolidated financial statements and a $770 increase in cash used in operating activities on the Company's condensed and consolidated statements of cash flows for 2017. 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. The Company adopted this update in the first quarter of 2018 with no material impact to the Company's consolidated financial statements and related disclosures. FASB Accounting Standards Update No. 2016-02 — Leases (Topic 842) In February 2016, the FASB issued ASU No. 2016-02, This ASU will require the recognition of lease assets and liabilities for operating leases with terms of more than 12 months. The presentation of leases within the consolidated statement of operations and cash flows will be substantially consistent with current accounting guidance. This ASU, which is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those annual periods, will have a material impact on our consolidated balance sheets. We have completed the implementation of a lease accounting system. We plan to adopt the ASU effective January 1, 2019 |
