Accounting Policies [Abstract]
Nature of Business and Summary of Significant Accounting Policies	Nature of Business and Summary of Significant Accounting Policies Nature of Business Qumu Corporation ("Qumu" or the "Company") provides the software solutions to create, manage, secure, distribute and measure the success of live and on-demand video for the enterprise. The Qumu platform enables global organizations to drive employee engagement, increase access to video, and modernize the workplace by providing a more efficient and effective way to share knowledge. The world’s largest organizations leverage the Qumu platform for a variety of cloud, on-premise and hybrid deployments. Use cases including self-service webcasting, sales enablement, internal communications, product training, regulatory compliance and customer engagement. The Company markets its products to customers primarily in North America, Europe and Asia. The Company views its operations and manages its business as one segment and one reporting unit. Factors used to identify the Company's single operating segment and reporting unit include the financial information available for evaluation by the chief operating decision maker in making decisions about how to allocate resources and assess performance. The Company markets its products and services through regional sales representatives and independent distributors in the United States and international markets. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, for which the current carrying amounts approximate fair market values based on quoted market prices or net asset value; warrant liabilities, for which the fair value of $2.9 million at December 31, 2019 is based on the Company's estimates of assumptions that market participants would use in pricing the liabilities. Revenue Recognition The Company adopted ASC 606, Revenue from Contracts with Customers , as of January 1, 2018. The Company generates revenue through the sale of enterprise video content management software, hardware, maintenance and support, and professional and other services. Software sales may take the form of a perpetual software license, a cloud-hosted software as a service (SaaS) or a term software license. Software licenses and appliances revenue includes sales of perpetual software licenses and hardware. Service revenue includes SaaS, term software licenses, maintenance and support, and professional and other services. An individual sale can range from a single year agreement for thousands of dollars to a multi-year agreement for over a million dollars. The Company follows a five-step model to assess each sale to a customer: identify the legally binding contract, identify the performance obligations, determine the transaction price, allocate the transaction price, and determine whether revenue will be recognized at a point in time or over time. Revenue is recognized upon transfer of control of promised products or services (i.e., performance obligations) to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for promised goods or services. The Company’s performance obligations are satisfied either over time (for cloud-hosted software as a service, maintenance and support, and other services) or at a point in time (for software licenses and hardware). The Company enters into contracts that can include various combinations of software licenses, appliances, maintenance and services, some of which are distinct and are accounted for as separate performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price of the contract to each distinct performance obligation, on a relative basis using its standalone selling price. The Company determines the standalone selling price for software-related elements, including professional services and software maintenance and support contracts, based on the price charged for the deliverable when sold separately. The Company's on-premise term software licenses and technical support for its on-premise term software licenses are distinct from each other. As a result, the software license is recognized upon transfer of control, which is at fulfillment. The revenue allocable to technical support is recognized ratably over the non-cancellable committed term of the agreement. Other items relating to charges collected from customers include reimbursable expenses, shipping and handling charges and sales taxes charges. Charges collected from customers as part of the Company's sales transactions are included in revenues and the associated costs are included in cost of revenues. Sales taxes charged to and collected from customers as part of the Company’s sales transactions are excluded from revenues and recorded as a liability to the applicable governmental taxing authority. Deferred Revenue Deferred revenue consists of billings or payments received in advance of revenue recognition and is recognized as the revenue recognition criteria are met. The deferred revenue balance does not represent the total contract value of annual or multi-year, non-cancellable subscription agreements. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as non-current deferred revenue. Deferred Sales Commissions Sales commissions represent the direct incremental costs related to the acquisition of customer contracts. The Company recognizes commissions as sales and marketing expense at the time the associated product revenue is recognized, requiring establishment of a deferred cost in the event a commission is paid prior to recognition of revenue. The deferred commission amounts are recoverable through the related future revenue streams under non-cancellable customer contracts and commission clawback provisions in the Company's sales compensation plans. Deferred commission costs included in prepaid expenses and other assets were $380,000 and $527,000 at December 31, 2019 and 2018 , respectively. Deferred commission costs in other assets, non-current were $138,000 and $33,000 at December 31, 2019 and 2018 , respectively. The Company recognized commissions expense of $1.9 million and $1.3 million during the years ended December 31, 2019 and 2018 , respectively. Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents are stated at fair value. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are initially recorded at a selling price, which approximates fair value upon the sale of goods or services to customers. The Company maintains an allowance for doubtful accounts to reflect accounts receivable at net realizable value. In judging the adequacy of the allowance for doubtful accounts, the Company considers multiple factors, including historical bad debt experience, the general economic environment, the need for specific client reserves and the aging of the Company’s receivables. A portion of this provision is included in operating expenses as a general and administrative expense and a portion of this provision is included as a reduction of license revenue. A considerable amount of judgment is required in assessing these factors. If the factors utilized in determining the allowance do not reflect future performance, then a change in the allowance for doubtful accounts would be necessary in the period such determination has been made, which would impact future results of operations. Changes to the allowance for doubtful accounts consisted of the following (in thousands): Year Ended December 31, Allowance for Doubtful Accounts: 2019 2018 2017 Balance at beginning of year $ 61 $ 21 $ 34 Write-offs (6 ) — (11 ) Change in provision (10 ) 40 (2 ) Balance at end of year $ 45 $ 61 $ 21 Inventories Inventories are stated at the lower of cost or market. Cost is determined on a first-in, first-out basis. The Company records provisions for potential excess, obsolete and slow-moving inventory. Results could be different if demand for the Company’s products decreased because of economic or competitive conditions, or if products became obsolete because of technical advancements in the industry or by the Company. Inventory included in prepaid expenses and other current assets was $350,000 and $191,000 as of December 31, 2019 and 2018 , respectively. Property and Equipment Property and equipment are stated at cost and depreciated on a straight-line basis over estimated useful lives ranging from one to seven years for most assets. Leasehold improvements are amortized using the straight-line method over the shorter of the property’s useful life or the term of the underlying lease. Repairs and maintenance costs are charged to operations as incurred. The asset cost and related accumulated depreciation or amortization are adjusted for asset retirement or disposal, with the resulting gain or loss, if any, credited or charged to results of operations. Long-lived Assets The Company continually monitors events and changes in circumstances that could indicate that carrying amounts of its long-lived assets, including property and equipment and intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through their undiscounted expected future cash flows. If the future undiscounted cash flows are less than the carrying amount of these assets, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets. Goodwill The Company records goodwill when consideration paid in a purchase acquisition exceeds the fair value of the net tangible assets and the identified intangible assets acquired. Goodwill is not amortized, but rather is tested for impairment annually or more frequently if facts and circumstances warrant a review. The Company has determined that there is a single reporting unit for the purpose of goodwill impairment tests. For purposes of assessing the impairment of goodwill, the Company annually, at its fiscal year end, estimates the fair value of the reporting unit and compares this amount to the carrying value of the reporting unit. If the Company determines that the carrying value of the reporting unit exceeds its fair value, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds its fair value. As of December 31, 2019 , the Company completed its annual impairment test of goodwill. Based upon that evaluation, the Company determined that its goodwill was not impaired. See Note 3–"Intangible Assets and Goodwill." Leases The Company is a lessee in several non-cancellable operating leases, primarily for office space, and finance leases, for certain IT equipment. Beginning January 1, 2019, the Company accounts for leases in accordance with ASU 2016-02, Leases , and the related amendments (collectively, "Topic 842"). The Company determines if an arrangement is or contains a lease at contract inception and recognizes a right of use (ROU) asset and a lease liability at the lease commencement date. For operating leases, the lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. For finance leases, the lease liability is initially measured in the same manner and at the same date as for operating leases, and is subsequently measured at amortized cost using the effective interest method. Key estimates and judgments in accounting for leases under Topic 842 include how the Company determines the discount rate it uses to discount the unpaid lease payments to present value, lease term and lease payments. – ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s information. Therefore, the Company uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. – The lease term for all of the Company’s leases includes the non-cancellable period of the lease plus any additional periods covered by either a Company option to extend the lease that the Company is reasonably certain to exercise, or an option to extend the lease controlled by the lessor. – Lease payments included in the measurement of the lease liability include the fixed payments owed over the lease term, termination penalties, amounts expected to be payable under a residual-value guarantee, and the exercise price of an option to purchase the asset if the Company is reasonably certain to exercise the option. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus any prepaid lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For finance leases, the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. The Company recognizes the lease payments associated with its short-term leases as an expense on a straight-line basis over the lease term. Derivatives Liability In conjunction with the debt financings completed in October 2016 and January 2018, the Company issued two warrants for the purchase of up to an aggregate of 1,239,286 shares of the Company's common stock, which remained unexercised and outstanding at December 31, 2019 . The warrant issued in conjunction with the October 21, 2016 debt financing (Hale warrant) for the purchase of up to 314,286 shares of the Company's common stock expires on October 21, 2026, has an exercise price of $2.80 per share and is transferable. The warrant issued in conjunction with the January 12, 2018 debt financing (ESW warrant) for the purchase of up to 925,000 shares of the Company's common stock expires on January 12, 2028, has an exercise price of $1.96 per share and is transferable. Additionally, the Company issued a warrant to a sales partner, iStudy Co., Ltd., for the purchase of up to 100,000 shares of the Company's common stock; the warrant expires on August 31, 2028, has an exercise price of $2.43 per share and is transferable. The Hale warrant and ESW warrant contain a cash settlement feature upon the occurrence of a certain events, essentially the sale of the Company as defined in the warrant agreements. Upon a sale of the Company, the holder of the iStudy warrant may exercise the warrant or may elect to receive the same consideration as it would have been entitled to receive upon the occurrence of such transaction if it had been the holder of the shares then issuable upon such exercise of the warrant. The Company accounts for the warrants, which are derivative financial instruments, as a current liability based upon the characteristics and provisions of the instruments. The warrants were determined to be ineligible for equity classification because of provisions that allow the holder under certain circumstances, essentially the sale of the Company as defined in the warrant agreements, to receive cash payment or other consideration at the option of the holder in lieu of the Company's common shares. Accordingly, the fair value of the warrants on the dates of issuance was recorded in the Company’s consolidated balance sheets as a liability. See Note 14–"Subsequent Event" for a discussion of the Company's merger agreement with Synacor, Inc., which impacts the cash settlement feature of the Hale warrant and ESW warrant. The Company estimates the fair value of this liability using option pricing models that are based on the individual characteristics of the warrants on the valuation date, which include the Company’s stock price and assumptions for expected volatility, expected life and risk-free interest rate, as well as the present value of the minimum cash payment component of the instrument for the warrants, when applicable. Changes in the assumptions used could have a material impact on the resulting fair value of each warrant. The primary inputs affecting the value of the warrant liability are the Company’s stock price and volatility in the Company's stock price, as well as assumptions about the probability and timing of certain events, such as a change in control or future equity offerings. Increases in the fair value of the underlying stock or increases in the volatility of the stock price generally result in a corresponding increase in the fair value of the warrant liability; conversely, decreases in the fair value of the underlying stock or decreases in the volatility of the stock price generally result in a corresponding decrease in the fair value of the warrant liability. Stock-Based Compensation The Company measures stock-based compensation based on the fair value of the award at the date of grant. For awards subject to time-based vesting, the Company recognizes stock-based compensation on a straight-line basis over the requisite service period for the entire award. Compensation cost is recognized over the vesting period to the extent the requisite service requirements are met, whether or not the award is ultimately exercised. Conversely, when the requisite service requirements are not met and the award is forfeited prior to vesting, any compensation expense previously recognized for the award is reversed. For awards subject to performance conditions, the Company accounts for compensation expense based upon the grant-date fair value of the awards applied to the best estimate of ultimate performance against the respective targets on a straight-line basis over the requisite vesting period of the awards. The performance conditions require management to make assumptions regarding the likelihood of achieving certain performance goals. Changes in these performance assumptions, as well as differences in actual results from management’s estimates, could result in estimated or actual values different from previously estimated fair values. Research and Development Costs Costs related to research, design and development of products are expensed to research and development as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. The Company uses the working model approach to determine technological feasibility. The Company’s products are released soon after technological feasibility has been established. As a result, the Company has not capitalized any software development costs because such costs have not been significant. Royalties for Third-Party Technology Royalties for third-party technology are either paid in advance and capitalized as prepaid royalties or are accrued as incurred and subsequently paid. These royalties are generally expensed to cost of revenue at the greater of a rate based on the contractual or estimated term or an effective royalty rate based on the total projected net revenue for contracts with guaranteed minimums. Each quarter, the Company evaluates the expected future realization of its prepaid royalties, as well as any minimum commitments not yet paid to determine amounts it deems unlikely to be realized through product sales. Any impairments or losses determined before the launch of a product are generally charged to general and administrative expense, and any impairments or losses determined post-launch are charged to cost of revenue. Unrecognized minimum royalty-based commitments are accounted for as executory contracts and, therefore, any losses on these commitments are recognized when the underlying intellectual property is abandoned (i.e., cease use) or the contractual rights to use the intellectual property are terminated. Income Taxes The Company provides for income taxes using the asset and liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some component or all of the deferred tax assets will not be realized. Tax rate changes are reflected in income during the period such changes are enacted. Foreign Currency Translation The functional currency for each of the Company’s international subsidiaries is the respective local currency. The Company translates its financial statements of consolidated entities whose functional currency is not the U.S. dollar into U.S. dollars. The Company translates its assets and liabilities at the exchange rate in effect as of the financial statement date and translates statement of operations accounts using the average exchange rate for the period. Exchange rate differences resulting from translation adjustments are accounted for as a component of accumulated other comprehensive loss. Gains or losses, whether realized or unrealized, due to transactions in foreign currencies are reflected in the consolidated statements of operations under the line item other income (expense). The net losses on foreign currency transactions for the years ended December 31, 2019 , 2018 and 2017 were $260,000 , $55,000 and $356,000 , respectively, and are included in other income (expense) in the consolidated statements of operations. Net Loss Per Share Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is calculated by adjusting both the numerator (net loss) and the denominator (weighted-average number of shares outstanding), giving effect to all potentially dilutive common shares from warrants. The treasury stock method is used for computing potentially dilutive common shares. Under this method, consideration that would be received upon exercise (as well as remaining compensation cost to be recognized for awards not yet vested) is assumed to be used to repurchase shares of stock in the market, with the net number of shares assumed to be issued added to the denominator. In addition, the numerator is adjusted to exclude the changes in the fair value of the dilutive warrants that are classified as a liability but may be settled in shares. For the years ended December 31, 2019 and 2018, the Company reported diluted net loss, as the impact of excluding the warrant income and related potentially dilutive shares was dilutive. Basic and diluted net loss per common share was the same for the year ended December 31, 2017 as the impact of all potentially dilutive securities outstanding was anti-dilutive. Comprehensive Income (Loss) Comprehensive income (loss) includes net income and items defined as other comprehensive income, such as unrealized gains and losses on foreign currency translation adjustments. Such items are reported in the consolidated statements of comprehensive income (loss). Recently Adopted Accounting Standards Leases (Topic 842) On January 1, 2019, the Company adopted ASU 2016-02, Leases , and the related amendments (collectively, "Topic 842"), using the modified retrospective transition approach as of the effective date. The comparative information in the consolidated financial statements has not been revised and continues to be reported under the previously applicable lease accounting guidance. In addition, the Company elected the package of practical expedients, which permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. The Company did not adopt the hindsight practical expedient, and therefore continues to utilize lease terms determined under pre-Topic 842 lease guidance. As a result of adopting Topic 842, the Company recognized additional operating lease liabilities of $1.9 million (of which $759,000 was current and $1.1 million was non-current) and corresponding ROU assets of $1.4 million as of January 1, 2019. Additionally, upon adoption of this standard, the Company recognized a cumulative-effect adjustment to accumulated deficit of $190,000 , net of taxes, as of January 1, 2019. The new lease guidance did not have a material impact on the Company's consolidated statements of operations or cash flows or compliance with debt covenants. For additional information regarding the Company's leases, see Note 4–"Commitments and Contingencies." The cumulative effect of the changes made to the Company's January 1, 2019 consolidated balance sheet from the modified retrospective adoption of Topic 842 is as follows (in thousands): December 31, Adjustments January 1, Assets: Property and equipment $ 545 $ 124 $ 669 Right of use assets – operating leases — 1,367 1,367 Liabilities: Accounts payable and other accrued liabilities $ 2,838 $ (211 ) $ 2,627 Operating lease liabilities — 759 759 Deferred rent 45 (45 ) — Operating lease liabilities, non-current — 1,100 1,100 Deferred rent, non-current 302 (302 ) — Stockholders’ equity: Accumulated deficit $ (58,875 ) $ 190 $ (58,685 ) Adjustments to accounts payable and other accrued liabilities include the derecognition of a contract termination obligation of $218,000 upon adoption of Topic 842. See Note 4–"Commitments and Contingencies" for additional information. Income Statement – Reporting Comprehensive Income (Topic 220) On January 1, 2019, the Company adopted ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220) , which allows a reclassification from accumulated other comprehensive income (loss) to retained earnings (accumulated deficit) for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 and requires certain disclosures regarding stranded tax effects in accumulated other comprehensive income (loss). The Company did not reclassify any income tax effects of the Tax Cuts and Jobs Act of 2017 from accumulated other comprehensive loss to accumulated deficit as a result of the adoption of this standard. Accounting Standards Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which simplifies the accounting for income taxes by removing exceptions within the general principles of Topic 740 regarding the calculation of deferred tax liabilities, the incremental approach for intraperiod tax allocation, and calculating income taxes in an interim period. In addition, the ASU adds clarifications to the accounting for franchise tax (or similar tax) which is partially based on income, evaluating tax basis of goodwill recognized from a business combination, and reflecting the effect of any enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The ASU is effective for fiscal years beginning after December 15, 2020, and will be applied either retrospectively or prospectively based upon the applicable amendments. Early adoption is permitted. The Company does not believe the impact of adopting this standard will be material to its consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820) , which changes the fair value measurement disclosure requirements of ASC 820. The ASU is effective for all entities for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Company does not believe the impact of adopting this standard will be material to its consolidated financial statements disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The purpose of the amendment is to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. The Company does not believe the impact of adopting this standard will be material to its consolidated financial statements.

The goodwill balance of $7.2 million at December 31, 2019 reflects the impact of foreign currency exchange rate fluctuations since the acquisition date. As of December 31, 2019 , the Company’s market capitalization, without a control premium, was greater than its book value and, as a result, the Company concluded there was no goodwill impairment. Declines in the Company’s market capitalization or a downturn in its future financial performance and/or future outlook could require the Company to record goodwill and other impairment charges. While a goodwill impairment charge is a non-cash charge, it would have a negative impact on the Company's results of operations.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Leases The Company is obligated under finance leases covering certain IT equipment that expire at various dates over the next three years. The Company also has non-cancellable operating leases, primarily for office space, that expire over the next five years . The Company has two leases that each contain a renewal option for a period of five years . Because the Company is not reasonably certain to exercise this option, the option is not considered in determining the lease term under Topic 842, which was adopted January 1, 2019. During the year ended December 31, 2019 , the Company commenced leases for office space in London, United Kingdom and Hyderabad, India. Many of the Company's leases include escalation clauses, renewal options and/or termination options that are factored into its determination of lease payments under Topic 842 when reasonably certain. These options to extend or terminate a lease are at the Company's discretion. The Company has elected to take the practical expedient and not separate lease and non-lease components of contracts. The Company estimates its incremental borrowing rate to discount the lease payments based on information available at lease commencement under Topic 842. The Company's lease agreements do not contain any material residual value guarantees. The components of lease cost were as follows (in thousands): Year Ended Operating lease cost $ 526 Finance lease cost: Amortization of right of use assets 106 Interest on lease liabilities 11 Total finance cost 117 Total lease cost $ 643 The Company's ROU assets and lease liabilities were reported in the consolidated balance sheet as follows (in thousands): Leases Classification on Balance Sheet December 31, Assets Operating Right of use assets – operating leases $ 1,746 Finance Property and equipment 130 Total lease assets $ 1,876 Liabilities Current Operating Operating lease liabilities $ 587 Finance Financing obligations 83 Non-current Operating Operating lease liabilities, non-current 1,587 Finance Financing obligations, non-current 83 Total lease liabilities $ 2,340 Other information related to leases is as follows (in thousands): Year Ended Supplemental cash flow information: Cash paid for amounts included in the measurement of lease liabilities Operating cash flow from operating leases $ 432 Financing cash flow from finance leases 77 ROU assets obtained in exchange for new lease obligations Finance leases $ 148 Weighted-average remaining lease term: Operating leases 3.8 years Finance leases 2.0 years Weighted-average discount rate: Operating leases 10.0 % Finance leases 6.2 % Future payments used in the measurement of lease liabilities on the consolidated balance sheet as of December 31, 2019 are as follows (in thousands): Operating leases Finance leases 2020 $ 764 $ 91 2021 712 80 2022 672 5 2023 294 — 2024 114 — Thereafter — — Total undiscounted lease payments 2,556 176 Less amount representing interest (382 ) (10 ) Present value of lease liabilities $ 2,174 $ 166 Subleases The Company determined that it had excess capacity at its Minneapolis, Minnesota headquarters and its London, United Kingdom office and effective May 1, 2018 and December 31, 2017, respectively, ceased using portions of its leased spaces, subsequently making them available for occupancy by sublessees. The Company also recorded losses related to the exit activities of $177,000 (net of adjustments for the derecognition of leasehold improvement and deferred rent balances related to the exit activity) and $72,000 , which are included in other income (expense) for the years ended December 31, 2018 and 2017, respectively. The Minneapolis sublease agreement had a term beginning May 2018 and extending through January 2023. On January 17, 2019, the Company terminated the Minneapolis sublease agreement, effective February 15, 2019, and contemporaneously modified the Company's primary lease agreement to relinquish the sublet space to the lessor, and be relieved of future lease payments for the previously sublet space, effective March 1, 2019. Upon modification of the Minneapolis lease agreement, the Company recognized a gain of $21,000 , which is reported in other income (expense) in the Company's consolidated statement of operations for the year ended December 31, 2019 . The London sublease agreement had a term beginning January 2018 and extending through September 2019. Prior to the adoption of Topic 842 on January 1, 2019, the Company accounted for the above subleases under guidance for exit and disposal activities (ASC 420). As such, the Company carried a lease contract termination liability of $218,000 as of December 31, 2018, representing the liability at fair value for the future contractual lease payments, net of expected sublease receipts. A reconciliation of the beginning and ending contract termination obligation balances is as follows (in thousands): London, England Minneapolis, Minnesota Total Contract termination obligation, January 1, 2017 $ — $ — $ — Lease termination costs incurred 72 — 72 Sublease payment received 122 — 122 Contract termination obligation, December 31, 2017 194 — 194 Lease termination costs incurred — 224 224 Accretion expense 14 19 33 Payments on obligations (189 ) (40 ) (229 ) Change in currency exchange rate (4 ) — (4 ) Contract termination obligation, December 31, 2018 15 203 218 Adjustment and reclassification upon adoption of Topic 842 (see Note 1) (15 ) (203 ) (218 ) Contract termination obligation, December 31, 2019 $ — $ — $ — The contract termination obligation is included in other accrued liabilities in the Company's consolidated balance sheets. Sublease income from the Company's subleases was $105,000 and $160,000 for the years ended December 31, 2019 and 2018 . No sublease income was recognized for the year ended December 31, 2017 . Term Loan The Company's term loan, which was paid in full during the year ended December 31, 2019 , is reported in the consolidated balance sheets as follows (in thousands): December 31, 2019 2018 Term loan, remaining principal balance $ — $ 4,000 Unamortized original issue discount — (481 ) Unamortized debt issuance costs — (88 ) Term loan $ — $ 3,431 Credit Agreement – ESW Holdings, Inc. On January 12, 2018, the Company and its wholly-owned subsidiary, Qumu, Inc., entered into a term loan credit agreement (the “ESW credit agreement”) with ESW Holdings, Inc. as lender and administrative agent pursuant to which the Company borrowed $10.0 million in the form of a term loan. Proceeds from the ESW credit agreement were used to pay the remaining outstanding balance of $8.0 million on its previous term loan plus a 10% prepayment fee of $800,000 on January 12, 2018. On November 12, 2019, the Company paid the remaining outstanding principal, accrued interest and prepayment fee on the ESW credit agreement as explained below. Interest on the term loan accrued and compounded monthly at a variable rate per annum equal to the prime rate plus 4.0% . In conjunction with this debt financing, the Company issued a warrant for the purchase of up to 925,000 shares of the Company's common stock, which remained unexercised and outstanding at December 31, 2019 . See Note 5–"Fair Value Measurements" and Note 14–"Subsequent Event" for further discussion of the warrant. On July 19, 2018, the Company paid $6.5 million on its outstanding term loan from ESW Holdings, Inc. under its term loan credit agreement dated January 12, 2018. The payment was comprised of principal of $6.0 million and accrued interest of $463,000 for the period January 12, 2018 to the payment date of July 19, 2018. The Company used a portion of the $9.8 million in net proceeds from the sale of its investment in BriefCam, Ltd. (see Note 10–"Sale of Investment in Software Company") to fund the prepayment. The Company determined that the prepayment of principal constituted a partial extinguishment of debt and, as such, recognized a $1.2 million loss related to the write down of unamortized debt discount and issuance costs. On November 12, 2019, the Company paid the remaining $4.8 million due on its outstanding term loan from ESW Holdings, Inc. under its term loan credit agreement dated January 12, 2018. The payment was comprised of principal of $4.0 million , accrued interest of $528,000 for the period July 19, 2018 to the payment date of November 12, 2019, and prepayment fee of $250,000 . The Company used a portion of the $8.2 million in net proceeds from the issuance of common stock, as described in Note 6–"Stockholders Equity" to fund the payment. The Company recognized a $348,000 loss on debt extinguishment related to the write down of $98,000 of unamortized debt discount and issuance costs and recognition of a $250,000 prepayment fee upon payment of the remaining term loan balance. Contingencies The Company is exposed to a number of asserted and unasserted claims encountered in the normal course of business. Legal costs related to loss contingencies are expensed as incurred. In the opinion of management, the resolution of these matters will not have a material adverse effect on the Company’s financial position or results of operations. The Company’s standard arrangements include provisions indemnifying customers against liabilities if the Company's products infringe a third-party’s intellectual property rights. The Company has not incurred any costs in its continuing operations as a result of such indemnifications and has not accrued any liabilities related to such contingent obligations in the accompanying consolidated financial statements.

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements A hierarchy for inputs used in measuring fair value is in place that distinguishes market data between observable independent market inputs and unobservable market assumptions by the reporting entity. The hierarchy is intended to maximize the use of observable inputs and minimize the use of unobservable inputs by requiring that the most observable inputs be used when available. Three levels within the hierarchy may be used to measure fair value: • Level 1: Inputs are unadjusted quoted prices in active markets for identical assets and liabilities. • Level 2: Inputs include data points that are observable such as quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) such as interest rates and yield curves that are observable for the asset or liability, either directly or indirectly. • Level 3: Inputs are generated from model-based techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect an entity’s own estimates of assumptions that market participants would use in pricing the asset or liability. In conjunction with the debt financings completed in October 2016 and January 2018, the Company issued two warrants for the purchase of up to an aggregate of 1,239,286 shares of the Company's common stock, which remained unexercised and outstanding at December 31, 2019 . The warrant issued in conjunction with the October 2016 debt financing (Hale warrant) for the purchase of up to 314,286 shares of the Company's common stock expires on October 21, 2026, has an exercise price of $2.80 per share and is transferable. The warrant issued in conjunction with the January 2018 debt financing (ESW warrant) for the purchase of up to 925,000 shares of the Company's common stock expires on January 12, 2028, has an exercise price of $1.96 per share and is transferable. Additionally, on August 31, 2018, the Company issued a warrant to a sales partner, iStudy Co., Ltd., (iStudy warrant) for the purchase of up to 100,000 shares of the Company's common stock; the warrant expires on August 31, 2028, has an exercise price of $2.43 per share and is transferable. The Hale warrant and ESW warrant contain a cash settlement feature upon the occurrence of a certain events, essentially the sale of the Company as defined in the warrant agreements. Upon a sale of the Company, the holder of the iStudy warrant may exercise the warrant or may elect to receive the same consideration as it would have been entitled to receive upon the occurrence of such transaction if it had been the holder of the shares then issuable upon such exercise of the warrant. As a result of these features, the warrants are subject to derivative accounting as prescribed under ASC 815. Accordingly, the fair value of the warrants on the dates of issuance was recorded in the Company’s consolidated balance sheets as a liability. See Note 14–"Subsequent Event" for a discussion of the Company's merger agreement with Synacor, Inc., which impacts the cash settlement feature of the Hale warrant and ESW warrant. The warrant liability was recorded in the Company's consolidated balance sheets at its fair value on the respective dates of issuance and is revalued on each subsequent balance sheet date until such instrument is exercised or expires, with any changes in the fair value between reporting periods recorded as other income or expense. During 2019 , 2018 and 2017 , the Company recorded a non-cash gain (loss) from the change in fair value of the warrant liability of $(141,000) , $368,000 and $74,000 , respectively. The gain (loss) for each year resulted from changes in inputs for the Company’s stock price, expected volatility, expected life and risk-free interest rates, as well as the present value of the minimum cash payment component of the instrument for the warrants, when applicable, along with management's assumptions including the probability and timing of certain events, such as a change in control or future equity offerings. The Company estimates the fair value of this liability using option pricing models that are based on the individual characteristics of the warrants on the valuation date, which include the Company’s stock price and assumptions for expected volatility, expected life and risk-free interest rate, as well as the present value of the minimum cash payment component of the instrument for the warrants, when applicable. Changes in the assumptions used could have a material impact on the resulting fair value of each warrant. The primary inputs affecting the value of the warrant liability are the Company’s stock price and volatility in the Company's stock price, as well as assumptions about the probability and timing of certain events, such as a change in control or future equity offerings. Increases in the fair value of the underlying stock or increases in the volatility of the stock price generally result in a corresponding increase in the fair value of the warrant liability; conversely, decreases in the fair value of the underlying stock or decreases in the volatility of the stock price generally result in a corresponding decrease in the fair value of the warrant liability. The Company's evaluation of the probability and timing of a change in control or future equity offering represents an unobservable input that may shorten or lengthen the expected life assumption input of the option pricing model, and may increase or decrease the discounted value of the minimum cash payment component of the warrant liability. The Company’s liabilities measured at fair value on a recurring basis and the fair value hierarchy utilized to determine such fair values is as follows at December 31, 2019 and 2018 (in thousands): Fair Value Measurements Using Total Fair Quoted Prices in Significant Other Significant Liabilities: Derivative warrant liability - ESW warrant $ 2,149 $ — $ — $ 2,149 Derivative warrant liability - Hale warrant 645 — — 645 Derivative warrant liability - iStudy 145 — — 145 Derivative warrant liability $ 2,939 $ — $ — $ 2,939 Fair Value Measurements Using Total Fair Quoted Prices in Significant Other Significant Liabilities: Derivative warrant liability - ESW warrant $ 2,015 $ — $ — $ 2,015 Derivative warrant liability - Hale warrant 750 — — 750 Derivative warrant liability - iStudy 33 — — 33 Derivative warrant liability $ 2,798 $ — $ — $ 2,798 The Company classified the warrant liability as Level 3 due to the lack of relevant observable market data over fair value inputs such as the probability-weighting of the various scenarios in the arrangements. The following table represents a rollforward of the fair value of the Level 3 instruments (significant unobservable inputs): Balance at December 31, 2018 $ 2,798 Change in fair value 141 Balance at December 31, 2019 $ 2,939

Revenue [Abstract]
Revenue	Revenue Nature of Products and Services Perpetual software licenses The Company’s perpetual software license arrangements grant customers the right to use the software indefinitely as it exists at the time of purchase. The Company recognizes revenue for distinct software licenses once the license period has begun and the software has been made available to the customer. Payments for perpetual software license contracts are generally received upon fulfillment of the software product. Term software licenses The Company's term software licenses differ from perpetual software licenses in that the customer's right to use the licensed product has a termination date. Term software licenses are recognized upon transfer of control, which is typically at fulfillment, resulting in up-front revenue recognition. The Company categorizes revenue from term software licenses as subscription, maintenance and support revenue in service revenues. Payments are generally received quarterly or annually in equal or near equal installments over the term of the agreement. Cloud-hosted software as a service Cloud-hosted software as a service (SaaS) arrangements grant customers the right to access and use the licensed products at the outset of an arrangement via third-party cloud providers. Updates are generally made available throughout the entire term of the arrangement, which is generally one to three years. The Company provides an online library and technical support resources in these cloud-hosted SaaS arrangements, which in conjunction with the SaaS license constitute a single, combined performance obligation, and revenue is recognized over the term of the license. Payments are generally received annually in advance of the service period. Hardware The Company sells appliances that are typically drop shipped from third-party suppliers selected by the Company. The transaction price allocated to the appliance is generally recognized as revenue at fulfillment when the customer obtains control of the product. Payments for appliances are generally received upon delivery of the hardware product. Maintenance and support Maintenance and support arrangements grant customers the right to software updates and technical support over the term of the maintenance and support contract. Revenue from maintenance and support is generally recognized ratably over the contract term beginning on the commencement date of each contract, which is upon fulfillment of the software obligation. Payments are generally received annually in advance of the service period. Professional services and training Professional services and training generally consist of software implementation, on-boarding services and best practices consulting. Revenue from professional services contracts is typically recognized as performed, generally using hours expended to measure progress. Services are generally invoiced monthly for work performed. Revenues by product category and geography The Company combines its products and services into three product categories and three geographic regions, based on customer location, as follows (in thousands): Year Ended 2019 2018 2017 Software licenses and appliances $ 4,903 $ 5,814 $ 5,982 Service Subscription, maintenance and support 18,249 17,132 19,374 Professional services and other 2,210 2,067 2,811 Total service 20,459 19,199 22,185 Total revenues $ 25,362 $ 25,013 $ 28,167 Year Ended 2019 2018 2017 North America $ 16,588 $ 16,639 $ 20,494 Europe 7,527 6,453 6,914 Asia 1,247 1,921 759 Total $ 25,362 $ 25,013 $ 28,167 Substantially all revenue from North America is sourced from customers in the United States. The Company has determined that reporting non-domestic revenue by country is not practicable. Significant Judgments The Company's contracts with customers typically contain promises to transfer multiple products and services to a customer. Judgment is required to determine whether each product and/or service is considered to be a distinct performance obligation that should be accounted for separately under the contract. The Company allocates the transaction price to the distinct performance obligations based on relative standalone selling price (“SSP”). The Company estimates SSP by maximizing use of observable prices such as the prices charged to customers on a standalone basis, established prices lists, contractually stated prices, profit margins and other entity-specific factors, or by using information such as market conditions and other observable inputs. However, the selling prices of its software licenses and cloud-hosted SaaS arrangements are highly variable. Thus, the Company estimates SSP for software licenses and cloud-hosted SaaS arrangements using the residual approach, determined based on total transaction price less the SSP of other goods and services promised in the contract. Determining whether licenses and services are distinct performance obligations that should be accounted for separately, or not distinct and thus accounted for together, requires significant judgment. In some arrangements, such as most of the Company’s license arrangements, the Company has concluded that the licenses and associated services are distinct from each other. In others, like the Company’s cloud-hosted SaaS arrangements, the license and certain services are not distinct from each other and therefore the Company has concluded that these promised goods and services are a single, combined performance obligation. If a group of agreements are so closely related that they are, in effect, part of a single arrangement, such agreements are deemed to be one arrangement for revenue recognition purposes. The Company exercises significant judgment to evaluate the relevant facts and circumstances in determining whether the separate agreements should be accounted for separately or as, in substance, a single arrangement. The Company’s judgments about whether a group of contracts comprise a single arrangement can affect the allocation of consideration to the distinct performance obligations, which could have an effect on results of operations for the periods involved. The Company is required to estimate the total consideration expected to be received from contracts with customers. In limited circumstances, the consideration expected to be received is variable based on the specific terms of the contract or based on the Company’s expectations of the term of the contract. Generally, the Company has not experienced significant returns from or refunds to customers. These estimates require significant judgment and the change in these estimates could have an effect on its results of operations during the periods involved. Contract Balances The timing of revenue recognition may differ from the timing of invoicing to customers and these timing differences result in receivables or contract liabilities (deferred revenue) on the Company’s consolidated balance sheet. The Company records deferred revenue when revenue is recognized subsequent to invoicing. The Company’s balances for contract assets totaled $1.1 million and $485,000 as of December 31, 2019 and 2018 , respectively. The Company’s balances for contract liabilities, which are included in current and non-current deferred revenue, totaled $11.6 million and $11.3 million as of December 31, 2019 and 2018 , respectively. During the year ended December 31, 2019 , the Company recognized $9.7 million of revenue that was included in the deferred revenue balance at the beginning of the period. All other activity in deferred revenue is due to the timing of invoices in relation to the timing of revenue as described above. Revenue allocated to remaining performance obligations represents the transaction price allocated to the performance obligations that are unsatisfied, or partially unsatisfied, which includes unearned revenue and amounts that will be invoiced and recognized as revenue in future periods. Contracted but unsatisfied performance obligations were approximately $19.3 million as of December 31, 2019 , of which the Company expects to recognize $11.3 million of revenue over the next 12 months and the remainder thereafter. During the years ended December 31, 2019 and 2018 , no revenue was recognized from performance obligations satisfied in previous periods. Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 to 60 days . In instances where the timing of revenue recognition differs from the timing of invoicing, the Company has determined that its contracts generally do not include a significant financing component. The primary purpose of invoicing terms is to provide customers with simplified and predictable ways of purchasing the Company’s products and services, and not to facilitate financing arrangements.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Stock-Based Compensation	Stock-Based Compensation The Company issues shares pursuant to the 2007 Stock Incentive Plan (the “2007 Plan”) which provides for the grant of stock incentive awards in the form of incentive and non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, performance stock, performance units and other awards in stock to certain key employees, non-employee directors and service providers. The exercise price of stock options granted under the 2007 Plan is equal to the market value on the date of grant. As of December 31, 2019 , there were 3,230,320 shares authorized under the 2007 Plan, of which 604,950 were available for future grant. The Company recognized the following amounts related to the Company’s share-based payment arrangements (in thousands): Year Ended December 31, 2019 2018 2017 Stock-based compensation cost charged against loss, before income tax benefit Stock options $ 331 $ 326 $ 366 Restricted stock and restricted stock units 521 566 765 Performance stock units 5 190 59 Total stock-based compensation costs $ 857 $ 1,082 $ 1,190 Stock-based compensation cost included in: Cost of revenues $ 26 $ 34 $ 39 Operating expenses 831 1,048 1,151 Total stock-based compensation costs $ 857 $ 1,082 $ 1,190 As of December 31, 2019 , compensation expense of $578,000 related to non-vested option awards was not yet recognized and is expected to be recognized over a weighted-average period of 2.4 years. As of December 31, 2019 , compensation expense of $468,000 related to non-vested shares and restricted share unit awards was not yet recognized and is expected to be recognized over a weighted-average period 2.2 years. Stock Options The fair value of each option award is estimated at the date of grant using the Black-Scholes option pricing model. The assumptions used to determine the fair value of stock option awards granted were as follows: Year Ended December 31, 2019 2018 2017 Expected life of options in years 4.70 - 4.75 4.54 - 4.75 4.75 Risk-free interest rate 1.8% - 2.5% 2.6% - 2.9% 1.7% - 2.0% Expected volatility 69.7% - 73.6% 69.6% - 70.5% 64.2% - 66.2% Expected dividend yield —% —% —% The Company reviews these assumptions at the time of each new option award and adjusts them as necessary to ensure proper option valuation. The expected life represents the period that the stock option awards are expected to be outstanding. The Company has concluded that its stock option exercise history does not provide a reasonable basis upon which to estimate expected term, and therefore it uses the simplified method for determining the expected life of stock options granted to employees in 2019 , 2018 and 2017 , which bases the expected life calculation on the average of the vesting term and the contractual term of the awards. The risk-free interest rate is based on the yield of constant maturity U.S. treasury bonds with a remaining term equal to the expected life of the awards. The Company estimated the stock price volatility using weekly price observations over the most recent historical period equal to the expected life of the awards.

Investment in Software Company	Sale of Investment in Software Company As of December 31, 2017, the Company held an investment reported in other assets, non-current, totaling $3.1 million in convertible preferred stock of BriefCam, Ltd. ("BriefCam"), a privately-held Israeli company. During 2018, Canon Inc. (“Canon”) acquired all of the outstanding shares of BriefCam and the Company received $9.7 million from the closing proceeds for its shares of BriefCam, as well as received $100,000 following the satisfaction of a contingency, resulting in a gain on sale of $6.6 million during the year ended December 31, 2018 . Additionally, during the year ended December 31, 2019 , the Company recognized a gain of $41,000 related to the release of cash from escrow in connection with the sale. Prior to its sale, the investment did not have a readily determinable fair value and was recorded at cost, less impairment, if any, plus or minus changes resulting from observable price changes in market-based transactions for an identical or similar investment of the same issuer and is included in other non-current assets. The Company's ownership interest was less than 20% . From the date of the Company's adoption of ASU 2016-01, Financial Instruments – Overall , on January 1, 2018 to the sale of BriefCam, there were no observable price changes or impairments related to the Company’s non-marketable investment in the equity security. The gain on sale was taxable in the U.S. and was offset for federal income tax purposes by current or prior-year tax losses but was subject to applicable state income taxes. The gain on sale was not taxable in Israel.

The loss carryforwards for state tax purposes will expire between 2020 and 2038 if not utilized. At December 31, 2019, $85.8 million of federal net operating loss carryforwards (losses originating in tax years beginning prior to January 1, 2018), expire in years 2022 through 2037, and federal net operating loss of $3.4 million generated since 2018 can be carryforward indefinitely and utilization is limited to 80% of taxable income. The net operating loss expiration related to the state income tax returns that the Company files varies by state. As of December 31, 2019 , the Company had federal and state research and development credit carryforwards of $3.3 million , net of Section 383 limitations, which will begin to expire in 2022 if not utilized. As a result of its acquisition of Qumu, Inc. in October 2011, utilization of U.S. net operating losses and tax credits of Qumu, Inc. are subject to annual limitations under Internal Revenue Code Sections 382 and 383, respectively. The Company has not completed an IRC Section 382 study since 2011. It is possible additional ownership changes have occurred, which may result in additional Section 382 and 383 limitations. Due to the valuation allowance, it is not expected that any such limitation will have an impact on the results of operations of the Company. The Company assessed that the valuation allowance against its U.S. deferred tax assets is still appropriate as of December 31, 2019 and 2018, based on the consideration of all available positive and negative evidence, using the “more likely than not” standard required by ASC 740, Income Taxes . During 2019 the U.K. shifted from a net deferred tax liability to net deferred tax asset position. As such, the Company no longer believes that it is more likely than not that the future results of the operations in the U.K. will generate sufficient taxable income to utilize the deferred tax assets. As of December 31, 2019, a full valuation allowance has been applied against its U.K. deferred tax assets. As of December 31, 2019 , the Company had a cumulative foreign tax loss carryforward of $2.0 million in the U.K. This amount can be carried forward indefinitely. The valuation allowance will be reviewed quarterly and will be maintained until sufficient positive evidence exists to support the reversal of the valuation allowance. On December 22, 2017, the Tax Cuts and Jobs Act (the Tax Act) was enacted, significantly altering U.S. corporate income tax law. Many of the new elements of the Tax Act became effective during 2018, including limitations on the deductibility of interest expense, limitations on executive compensation, as well as international provisions. The Company has considered and incorporated the new provisions into its tax calculations. Such provisions included in the Tax Act did not significantly impact the Company in 2019 and 2018, due to the full valuation allowance on deferred tax assets. The Company may repatriate cash associated with undistributed earnings of its foreign subsidiaries, such that they are not reinvested indefinitely. The repatriation of cash and cash equivalents held by the Company's international subsidiaries would not result in an adverse tax impact on cash given that the future tax consequences of repatriation are expected to be insignificant as a result of the Tax Cuts and Jobs Act of 2017. A reconciliation of the beginning and ending amounts of gross unrecognized tax benefits is presented in the table below (in thousands): Year Ended December 31, 2019 2018 Gross unrecognized tax benefits at beginning of year $ 1,724 $ 1,136 Increases related to: Prior year income tax positions 7 2 Current year income tax positions 49 586 Gross unrecognized tax benefits at end of year $ 1,780 $ 1,724 Included in the balance of unrecognized tax benefits at December 31, 2019 are potential benefits of $585,000 that, if recognized, would affect the effective tax rate. The change in the liability for gross unrecognized tax benefits reflects an increase in reserves established for federal and state uncertain tax positions. The Company does not anticipate that the total amount of unrecognized tax benefits as of December 31, 2019 will change significantly by December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. Total accrued interest and penalties amounted to $28,000 and $5,600 on a gross basis at December 31, 2019 and 2018 , respectively, and are excluded from the reconciliation of unrecognized tax benefits presented above. Interest and penalties recognized in the consolidated statements of operations related to uncertain tax positions amounted to net tax expense of $22,000 and $4,200 in 2019 and 2018 , respectively. The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions.

Subsequent Events [Abstract]
Subsequent Event	Subsequent Event On February 11, 2020, Qumu entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) for a proposed “merger of equals” transaction with Synacor, Inc. (“Synacor”), and Quantum Merger Sub I, Inc., a direct, wholly owned subsidiary of Synacor (“Merger Sub”). Pursuant to the Merger Agreement, and subject to the conditions in the Merger Agreement, Merger Sub will merge with and into Qumu (the “Merger”), with Qumu surviving the Merger as a wholly owned subsidiary of Synacor. At the effective time of the Merger, by virtue of the Merger and without any action on the part of Synacor, Qumu, Merger Sub or any holder of any of the securities of Synacor, Qumu or Merger Sub, each share of common stock of Qumu issued and outstanding immediately prior to the effective time (other than the shares that are owned by Qumu, Synacor or Merger Sub) will be converted into the right to receive 1.61 newly issued shares of common stock of Synacor. Immediately prior to the effective time, each currently outstanding Qumu restricted stock award, restricted stock unit and stock option (the “Qumu Stock Awards”) will become fully vested and any restrictions or risk of forfeiture will lapse. Any Qumu Common Stock required to be issued to the holder of such Qumu Stock Award following such acceleration of vesting or lapse of restrictions shall be deemed to be issued and outstanding as of immediately prior to the effective time and converted into the right to receive Synacor Common Stock at the exchange ratio. Subject to the terms and conditions set forth in the Merger Agreement, at the effective time, each currently outstanding Qumu stock option will terminate and be cancelled, with the holder thereof becoming entitled to receive, on the date on which the effective time occurs, an amount in cash, without interest and subject to applicable withholding, equal to: (i) the excess, if any, of (A) the last reported sales price on Nasdaq of one share of Qumu Common Stock on the Closing Date over (B) the exercise price per share of Qumu Common Stock subject to such Qumu stock option multiplied by (ii) the number of shares of Qumu Common Stock subject to such Qumu stock option at the effective time. However, if the exercise price of such Qumu stock option is equal to or greater than the last reported sales price on Nasdaq on such date, such Qumu stock option will terminate and be cancelled without any consideration being payable in respect thereof. At the effective time, by virtue of the Merger and without necessity of any further action, each Qumu equity award that is granted on or after February 11, 2020, is held by a then current service provider of Qumu and is outstanding immediately prior to the effective time will be assumed by Synacor as specified in the Merger Agreement. The consummation of the Merger is subject to customary closing conditions, including, among others, the approval of the Merger Agreement by Qumu shareholders and the approval of the issuance of shares of Synacor common stock pursuant to the Merger Agreement by the Synacor stockholders. The parties expect the Merger will be completed in the second quarter of calendar year 2020. The foregoing description of the Merger and Merger Agreement does not purport to be complete and is qualified in its entirety by reference to the Merger Agreement, which is filed as Exhibit 2.1 to our Current Report on Form 8-K, filed with the SEC on February 11, 2020. In addition, see Part I – Item 1A – Risk Factors – Risks Relating to the Merger. In connection with the Merger, each holder of a warrant will have the right to receive, upon exercise of the warrant, 1.61 newly issued shares of common stock of Synacor for each share of Qumu common stock then issuable upon such exercise of the warrant. Alternatively, the ESW warrant and Hale warrant each provide that at the request of the holder, Qumu must purchase the warrant from such holder for a purchase price, payable in cash, equal to the greater of the original issuance value in respect of the remaining unexercised portion of the warrant and the Black-Scholes value of the remaining unexercised portion of the warrant through the date of the consummation of the Merger as determined in accordance the warrant. The original issuance value of the ESW warrant is $1,936,535 and the original issuance value of the Hale warrant is $915,389 . The iStudy warrant holder has no right to require a cash purchase of the warrant and the portion of the iStudy warrant not exercised prior to the closing of the Merger will expire at the time of the closing of the Merger. The rights of the holders of the ESW warrant and the Hale warrant to exercise the warrants will expire at the closing of the Merger and any cash purchase price must be paid within five trading days of the request that Qumu purchase the warrant.

Nature of Business and Summar_2

Nature of Business and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2019
Accounting Policies [Abstract]
Nature of Business and Principles of Consolidation	Nature of Business Qumu Corporation ("Qumu" or the "Company") provides the software solutions to create, manage, secure, distribute and measure the success of live and on-demand video for the enterprise. The Qumu platform enables global organizations to drive employee engagement, increase access to video, and modernize the workplace by providing a more efficient and effective way to share knowledge. The world’s largest organizations leverage the Qumu platform for a variety of cloud, on-premise and hybrid deployments. Use cases including self-service webcasting, sales enablement, internal communications, product training, regulatory compliance and customer engagement. The Company markets its products to customers primarily in North America, Europe and Asia. The Company views its operations and manages its business as one segment and one reporting unit. Factors used to identify the Company's single operating segment and reporting unit include the financial information available for evaluation by the chief operating decision maker in making decisions about how to allocate resources and assess performance. The Company markets its products and services through regional sales representatives and independent distributors in the United States and international markets. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments consist primarily of cash and cash equivalents, for which the current carrying amounts approximate fair market values based on quoted market prices or net asset value; warrant liabilities, for which the fair value of $2.9 million at December 31, 2019 is based on the Company's estimates of assumptions that market participants would use in pricing the liabilities.
Revenue Recognition	Revenue Recognition The Company adopted ASC 606, Revenue from Contracts with Customers , as of January 1, 2018. The Company generates revenue through the sale of enterprise video content management software, hardware, maintenance and support, and professional and other services. Software sales may take the form of a perpetual software license, a cloud-hosted software as a service (SaaS) or a term software license. Software licenses and appliances revenue includes sales of perpetual software licenses and hardware. Service revenue includes SaaS, term software licenses, maintenance and support, and professional and other services. An individual sale can range from a single year agreement for thousands of dollars to a multi-year agreement for over a million dollars. The Company follows a five-step model to assess each sale to a customer: identify the legally binding contract, identify the performance obligations, determine the transaction price, allocate the transaction price, and determine whether revenue will be recognized at a point in time or over time. Revenue is recognized upon transfer of control of promised products or services (i.e., performance obligations) to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for promised goods or services. The Company’s performance obligations are satisfied either over time (for cloud-hosted software as a service, maintenance and support, and other services) or at a point in time (for software licenses and hardware). The Company enters into contracts that can include various combinations of software licenses, appliances, maintenance and services, some of which are distinct and are accounted for as separate performance obligations. For contracts with multiple performance obligations, the Company allocates the transaction price of the contract to each distinct performance obligation, on a relative basis using its standalone selling price. The Company determines the standalone selling price for software-related elements, including professional services and software maintenance and support contracts, based on the price charged for the deliverable when sold separately. The Company's on-premise term software licenses and technical support for its on-premise term software licenses are distinct from each other. As a result, the software license is recognized upon transfer of control, which is at fulfillment. The revenue allocable to technical support is recognized ratably over the non-cancellable committed term of the agreement. Other items relating to charges collected from customers include reimbursable expenses, shipping and handling charges and sales taxes charges. Charges collected from customers as part of the Company's sales transactions are included in revenues and the associated costs are included in cost of revenues. Sales taxes charged to and collected from customers as part of the Company’s sales transactions are excluded from revenues and recorded as a liability to the applicable governmental taxing authority.
Deferred Revenue	Deferred Revenue Deferred revenue consists of billings or payments received in advance of revenue recognition and is recognized as the revenue recognition criteria are met. The deferred revenue balance does not represent the total contract value of annual or multi-year, non-cancellable subscription agreements. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as current deferred revenue, and the remaining portion is recorded as non-current deferred revenue.
Deferred Commissions	Deferred Sales Commissions Sales commissions represent the direct incremental costs related to the acquisition of customer contracts. The Company recognizes commissions as sales and marketing expense at the time the associated product revenue is recognized, requiring establishment of a deferred cost in the event a commission is paid prior to recognition of revenue. The deferred commission amounts are recoverable through the related future revenue streams under non-cancellable customer contracts and commission clawback provisions in the Company's sales compensation plans. Deferred commission costs included in prepaid expenses and other assets were $380,000 and $527,000 at December 31, 2019 and 2018 , respectively. Deferred commission costs in other assets, non-current were $138,000 and $33,000 at December 31, 2019 and 2018 , respectively. The Company recognized commissions expense of $1.9 million and $1.3 million during the years ended December 31, 2019 and 2018 , respectively.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash and cash equivalents are stated at fair value.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are initially recorded at a selling price, which approximates fair value upon the sale of goods or services to customers. The Company maintains an allowance for doubtful accounts to reflect accounts receivable at net realizable value. In judging the adequacy of the allowance for doubtful accounts, the Company considers multiple factors, including historical bad debt experience, the general economic environment, the need for specific client reserves and the aging of the Company’s receivables. A portion of this provision is included in operating expenses as a general and administrative expense and a portion of this provision is included as a reduction of license revenue. A considerable amount of judgment is required in assessing these factors. If the factors utilized in determining the allowance do not reflect future performance, then a change in the allowance for doubtful accounts would be necessary in the period such determination has been made, which would impact future results of operations.
Inventories	Inventories Inventories are stated at the lower of cost or market. Cost is determined on a first-in, first-out basis. The Company records provisions for potential excess, obsolete and slow-moving inventory. Results could be different if demand for the Company’s products decreased because of economic or competitive conditions, or if products became obsolete because of technical advancements in the industry or by the Company. Inventory included in prepaid expenses and other current assets was $350,000 and $191,000 as of December 31, 2019 and 2018 , respectively.
Property and Equipment	Property and Equipment Property and equipment are stated at cost and depreciated on a straight-line basis over estimated useful lives ranging from one to seven years for most assets. Leasehold improvements are amortized using the straight-line method over the shorter of the property’s useful life or the term of the underlying lease. Repairs and maintenance costs are charged to operations as incurred. The asset cost and related accumulated depreciation or amortization are adjusted for asset retirement or disposal, with the resulting gain or loss, if any, credited or charged to results of operations.
Long-lived Assets	Long-lived Assets The Company continually monitors events and changes in circumstances that could indicate that carrying amounts of its long-lived assets, including property and equipment and intangible assets may not be recoverable. When such events or changes in circumstances occur, the Company assesses the recoverability of long-lived assets by determining whether the carrying value of such assets will be recovered through their undiscounted expected future cash flows. If the future undiscounted cash flows are less than the carrying amount of these assets, the Company recognizes an impairment loss based on the excess of the carrying amount over the fair value of the assets.
Goodwill	Goodwill The Company records goodwill when consideration paid in a purchase acquisition exceeds the fair value of the net tangible assets and the identified intangible assets acquired. Goodwill is not amortized, but rather is tested for impairment annually or more frequently if facts and circumstances warrant a review. The Company has determined that there is a single reporting unit for the purpose of goodwill impairment tests. For purposes of assessing the impairment of goodwill, the Company annually, at its fiscal year end, estimates the fair value of the reporting unit and compares this amount to the carrying value of the reporting unit. If the Company determines that the carrying value of the reporting unit exceeds its fair value, an impairment charge is recognized in the amount by which the carrying amount of the asset exceeds its fair value. As of December 31, 2019 , the Company completed its annual impairment test of goodwill. Based upon that evaluation, the Company determined that its goodwill was not impaired. See Note 3–"Intangible Assets and Goodwill."
Leases	Leases The Company is a lessee in several non-cancellable operating leases, primarily for office space, and finance leases, for certain IT equipment. Beginning January 1, 2019, the Company accounts for leases in accordance with ASU 2016-02, Leases , and the related amendments (collectively, "Topic 842"). The Company determines if an arrangement is or contains a lease at contract inception and recognizes a right of use (ROU) asset and a lease liability at the lease commencement date. For operating leases, the lease liability is initially and subsequently measured at the present value of the unpaid lease payments at the lease commencement date. For finance leases, the lease liability is initially measured in the same manner and at the same date as for operating leases, and is subsequently measured at amortized cost using the effective interest method. Key estimates and judgments in accounting for leases under Topic 842 include how the Company determines the discount rate it uses to discount the unpaid lease payments to present value, lease term and lease payments. – ASC 842 requires a lessee to discount its unpaid lease payments using the interest rate implicit in the lease or, if that rate cannot be readily determined, its incremental borrowing rate. Generally, the Company cannot determine the interest rate implicit in the lease because it does not have access to the lessor’s information. Therefore, the Company uses its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate for a lease is the rate of interest it would have to pay on a collateralized basis to borrow an amount equal to the lease payments under similar terms. – The lease term for all of the Company’s leases includes the non-cancellable period of the lease plus any additional periods covered by either a Company option to extend the lease that the Company is reasonably certain to exercise, or an option to extend the lease controlled by the lessor. – Lease payments included in the measurement of the lease liability include the fixed payments owed over the lease term, termination penalties, amounts expected to be payable under a residual-value guarantee, and the exercise price of an option to purchase the asset if the Company is reasonably certain to exercise the option. The ROU asset is initially measured at cost, which comprises the initial amount of the lease liability adjusted for lease payments made at or before the lease commencement date, plus any initial direct costs incurred less any lease incentives received. For operating leases, the ROU asset is subsequently measured throughout the lease term at the carrying amount of the lease liability, plus initial direct costs, plus any prepaid lease payments, less the unamortized balance of lease incentives received. Lease expense for lease payments is recognized on a straight-line basis over the lease term. For finance leases, the ROU asset is subsequently amortized using the straight-line method from the lease commencement date to the earlier of the end of its useful life or the end of the lease term. The Company has elected not to recognize ROU assets and lease liabilities for short-term leases that have a lease term of 12 months or less. The Company recognizes the lease payments associated with its short-term leases as an expense on a straight-line basis over the lease term.
Derivative Liability	Derivatives Liability In conjunction with the debt financings completed in October 2016 and January 2018, the Company issued two warrants for the purchase of up to an aggregate of 1,239,286 shares of the Company's common stock, which remained unexercised and outstanding at December 31, 2019 . The warrant issued in conjunction with the October 21, 2016 debt financing (Hale warrant) for the purchase of up to 314,286 shares of the Company's common stock expires on October 21, 2026, has an exercise price of $2.80 per share and is transferable. The warrant issued in conjunction with the January 12, 2018 debt financing (ESW warrant) for the purchase of up to 925,000 shares of the Company's common stock expires on January 12, 2028, has an exercise price of $1.96 per share and is transferable. Additionally, the Company issued a warrant to a sales partner, iStudy Co., Ltd., for the purchase of up to 100,000 shares of the Company's common stock; the warrant expires on August 31, 2028, has an exercise price of $2.43 per share and is transferable. The Hale warrant and ESW warrant contain a cash settlement feature upon the occurrence of a certain events, essentially the sale of the Company as defined in the warrant agreements. Upon a sale of the Company, the holder of the iStudy warrant may exercise the warrant or may elect to receive the same consideration as it would have been entitled to receive upon the occurrence of such transaction if it had been the holder of the shares then issuable upon such exercise of the warrant. The Company accounts for the warrants, which are derivative financial instruments, as a current liability based upon the characteristics and provisions of the instruments. The warrants were determined to be ineligible for equity classification because of provisions that allow the holder under certain circumstances, essentially the sale of the Company as defined in the warrant agreements, to receive cash payment or other consideration at the option of the holder in lieu of the Company's common shares. Accordingly, the fair value of the warrants on the dates of issuance was recorded in the Company’s consolidated balance sheets as a liability. See Note 14–"Subsequent Event" for a discussion of the Company's merger agreement with Synacor, Inc., which impacts the cash settlement feature of the Hale warrant and ESW warrant. The Company estimates the fair value of this liability using option pricing models that are based on the individual characteristics of the warrants on the valuation date, which include the Company’s stock price and assumptions for expected volatility, expected life and risk-free interest rate, as well as the present value of the minimum cash payment component of the instrument for the warrants, when applicable. Changes in the assumptions used could have a material impact on the resulting fair value of each warrant. The primary inputs affecting the value of the warrant liability are the Company’s stock price and volatility in the Company's stock price, as well as assumptions about the probability and timing of certain events, such as a change in control or future equity offerings. Increases in the fair value of the underlying stock or increases in the volatility of the stock price generally result in a corresponding increase in the fair value of the warrant liability; conversely, decreases in the fair value of the underlying stock or decreases in the volatility of the stock price generally result in a corresponding decrease in the fair value of the warrant liability.
Stock-Based Compensation	Stock-Based Compensation The Company measures stock-based compensation based on the fair value of the award at the date of grant. For awards subject to time-based vesting, the Company recognizes stock-based compensation on a straight-line basis over the requisite service period for the entire award. Compensation cost is recognized over the vesting period to the extent the requisite service requirements are met, whether or not the award is ultimately exercised. Conversely, when the requisite service requirements are not met and the award is forfeited prior to vesting, any compensation expense previously recognized for the award is reversed. For awards subject to performance conditions, the Company accounts for compensation expense based upon the grant-date fair value of the awards applied to the best estimate of ultimate performance against the respective targets on a straight-line basis over the requisite vesting period of the awards. The performance conditions require management to make assumptions regarding the likelihood of achieving certain performance goals. Changes in these performance assumptions, as well as differences in actual results from management’s estimates, could result in estimated or actual values different from previously estimated fair values.
Research and Development Costs	Research and Development Costs Costs related to research, design and development of products are expensed to research and development as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. The Company uses the working model approach to determine technological feasibility. The Company’s products are released soon after technological feasibility has been established. As a result, the Company has not capitalized any software development costs because such costs have not been significant.
Royalties for Third-Party Technology	Royalties for Third-Party Technology Royalties for third-party technology are either paid in advance and capitalized as prepaid royalties or are accrued as incurred and subsequently paid. These royalties are generally expensed to cost of revenue at the greater of a rate based on the contractual or estimated term or an effective royalty rate based on the total projected net revenue for contracts with guaranteed minimums. Each quarter, the Company evaluates the expected future realization of its prepaid royalties, as well as any minimum commitments not yet paid to determine amounts it deems unlikely to be realized through product sales. Any impairments or losses determined before the launch of a product are generally charged to general and administrative expense, and any impairments or losses determined post-launch are charged to cost of revenue. Unrecognized minimum royalty-based commitments are accounted for as executory contracts and, therefore, any losses on these commitments are recognized when the underlying intellectual property is abandoned (i.e., cease use) or the contractual rights to use the intellectual property are terminated.
Income Taxes	Income Taxes The Company provides for income taxes using the asset and liability method, which requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some component or all of the deferred tax assets will not be realized. Tax rate changes are reflected in income during the period such changes are enacted.
Foreign Currency Translation	Foreign Currency Translation The functional currency for each of the Company’s international subsidiaries is the respective local currency. The Company translates its financial statements of consolidated entities whose functional currency is not the U.S. dollar into U.S. dollars. The Company translates its assets and liabilities at the exchange rate in effect as of the financial statement date and translates statement of operations accounts using the average exchange rate for the period. Exchange rate differences resulting from translation adjustments are accounted for as a component of accumulated other comprehensive loss. Gains or losses, whether realized or unrealized, due to transactions in foreign currencies are reflected in the consolidated statements of operations under the line item other income (expense). The net losses on foreign currency transactions for the years ended December 31, 2019 , 2018 and 2017 were $260,000 , $55,000 and $356,000 , respectively, and are included in other income (expense) in the consolidated statements of operations.
Net Loss Per Share	Net Loss Per Share Basic net loss per common share is computed by dividing net loss by the weighted-average number of common shares outstanding during the period. Diluted net loss per share is calculated by adjusting both the numerator (net loss) and the denominator (weighted-average number of shares outstanding), giving effect to all potentially dilutive common shares from warrants. The treasury stock method is used for computing potentially dilutive common shares. Under this method, consideration that would be received upon exercise (as well as remaining compensation cost to be recognized for awards not yet vested) is assumed to be used to repurchase shares of stock in the market, with the net number of shares assumed to be issued added to the denominator. In addition, the numerator is adjusted to exclude the changes in the fair value of the dilutive warrants that are classified as a liability but may be settled in shares. For the years ended December 31, 2019 and 2018, the Company reported diluted net loss, as the impact of excluding the warrant income and related potentially dilutive shares was dilutive.
Comprehensive Income (Loss)	Comprehensive Income (Loss) Comprehensive income (loss) includes net income and items defined as other comprehensive income, such as unrealized gains and losses on foreign currency translation adjustments. Such items are reported in the consolidated statements of comprehensive income (loss).
New Accounting Pronouncements	Recently Adopted Accounting Standards Leases (Topic 842) On January 1, 2019, the Company adopted ASU 2016-02, Leases , and the related amendments (collectively, "Topic 842"), using the modified retrospective transition approach as of the effective date. The comparative information in the consolidated financial statements has not been revised and continues to be reported under the previously applicable lease accounting guidance. In addition, the Company elected the package of practical expedients, which permits the Company not to reassess under the new standard its prior conclusions about lease identification, lease classification and initial direct costs. The Company did not adopt the hindsight practical expedient, and therefore continues to utilize lease terms determined under pre-Topic 842 lease guidance. As a result of adopting Topic 842, the Company recognized additional operating lease liabilities of $1.9 million (of which $759,000 was current and $1.1 million was non-current) and corresponding ROU assets of $1.4 million as of January 1, 2019. Additionally, upon adoption of this standard, the Company recognized a cumulative-effect adjustment to accumulated deficit of $190,000 , net of taxes, as of January 1, 2019. The new lease guidance did not have a material impact on the Company's consolidated statements of operations or cash flows or compliance with debt covenants. For additional information regarding the Company's leases, see Note 4–"Commitments and Contingencies." The cumulative effect of the changes made to the Company's January 1, 2019 consolidated balance sheet from the modified retrospective adoption of Topic 842 is as follows (in thousands): December 31, Adjustments January 1, Assets: Property and equipment $ 545 $ 124 $ 669 Right of use assets – operating leases — 1,367 1,367 Liabilities: Accounts payable and other accrued liabilities $ 2,838 $ (211 ) $ 2,627 Operating lease liabilities — 759 759 Deferred rent 45 (45 ) — Operating lease liabilities, non-current — 1,100 1,100 Deferred rent, non-current 302 (302 ) — Stockholders’ equity: Accumulated deficit $ (58,875 ) $ 190 $ (58,685 ) Adjustments to accounts payable and other accrued liabilities include the derecognition of a contract termination obligation of $218,000 upon adoption of Topic 842. See Note 4–"Commitments and Contingencies" for additional information. Income Statement – Reporting Comprehensive Income (Topic 220) On January 1, 2019, the Company adopted ASU 2018-02, Income Statement – Reporting Comprehensive Income (Topic 220) , which allows a reclassification from accumulated other comprehensive income (loss) to retained earnings (accumulated deficit) for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 and requires certain disclosures regarding stranded tax effects in accumulated other comprehensive income (loss). The Company did not reclassify any income tax effects of the Tax Cuts and Jobs Act of 2017 from accumulated other comprehensive loss to accumulated deficit as a result of the adoption of this standard. Accounting Standards Not Yet Adopted In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes , which simplifies the accounting for income taxes by removing exceptions within the general principles of Topic 740 regarding the calculation of deferred tax liabilities, the incremental approach for intraperiod tax allocation, and calculating income taxes in an interim period. In addition, the ASU adds clarifications to the accounting for franchise tax (or similar tax) which is partially based on income, evaluating tax basis of goodwill recognized from a business combination, and reflecting the effect of any enacted changes in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The ASU is effective for fiscal years beginning after December 15, 2020, and will be applied either retrospectively or prospectively based upon the applicable amendments. Early adoption is permitted. The Company does not believe the impact of adopting this standard will be material to its consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-13, Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820) , which changes the fair value measurement disclosure requirements of ASC 820. The ASU is effective for all entities for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Company does not believe the impact of adopting this standard will be material to its consolidated financial statements disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment . The purpose of the amendment is to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. This standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022. Early adoption is permitted. The Company does not believe the impact of adopting this standard will be material to its consolidated financial statements.
