| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP). The consolidated financial statements include accounts of Limelight and our wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated. In addition, certain other reclassifications have been made to prior period amounts to conform to the current period presentation. Use of Estimates The preparation of the consolidated financial statements and related disclosures in conformity with U.S. GAAP requires management to make judgments, assumptions, and estimates that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results and outcomes may differ from those estimates. The results of operations presented in this Annual Report on Form 10-K are not necessarily indicative of the results that may be expected for the year ending December 31, 2021, or for any future periods. Foreign Currency Translation The functional currency of our international subsidiaries is the local currency. We translate assets and liabilities of foreign subsidiaries, whose functional currency is their local currency, at exchange rates in effect at the balance sheet date. We translate revenue and expenses at the monthly average exchange rates. We include accumulated net translation adjustments in stockholders’ equity as a component of accumulated other comprehensive income (loss). Due to changes in exchange rates between reporting periods and changes in certain account balances, the foreign currency translation adjustment will change from period to period. During the years ended December 31, 2020, 2019, and 2018, we recorded foreign currency translation gains (losses) of $1,750, $782, and $(1,733), respectively, in our statements of comprehensive income (loss). Our entities occasionally transact in currencies other than their functional currencies. Assets denominated in foreign currencies other than that of the functional currency of the entity are remeasured at period-end exchange rates. Foreign currency-based revenue and expense transactions are measured at transaction date exchange rates. During the years ended December 31, 2020, 2019, and 2018, we recorded a foreign currency re-measurement gain (loss) of approximately $(368), $24, and $(405), respectively, in other income (expense) in the consolidated statements of operations. Recent Accounting Standards Adopted Accounting Standards In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, which requires measurement and recognition of expected credit losses for financial assets held. The standard is to be applied through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. We adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures and there was no cumulative-effect adjustment required. In January 2017, the FASB issued ASU 2017-04, which simplifies the accounting for goodwill impairment. The updated guidance eliminates Step 2 of the impairment test, which requires entities to calculate the implied fair value of goodwill to measure a goodwill impairment charge. Instead, entities will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value, determined in Step 1. We adopted this guidance effective January 1, 2020, using a prospective approach. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-13, which removes, modifies and adds to the disclosure requirements on fair value measurements in Topic 820. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this updated guidance and delay adoption of the additional disclosures until their effective date. We adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. In August 2018, the FASB issued ASU 2018-15 , to help entities evaluate the accounting for fees paid by a customer in a cloud computing arrangement (hosting arrangement) by providing guidance for determining when the arrangement includes a software license. The amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments . We adopted this guidance effective January 1, 2020. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. Recently Issued Accounting Standards In December 2019, the FASB issued ASU 2019-12 to simplifying the accounting for income taxes. ASU 2019-12 is intended to simplify various aspects related to accounting for income taxes, eliminates certain exceptions to the general principles in the Accounting Standards Codification (ASC) Topic 740 related to intra-period tax allocation, simplifies when companies recognize deferred taxes in an interim period, and clarifies certain aspects of the current guidance to promote consistent application. This guidance is effective for public business entities for fiscal years beginning after December 15, 2020, and for interim periods within those fiscal years, with early adoption permitted. ASU 2019-12 requires a retrospective, modified retrospective or prospective transition approach for individual aspects of the ASU. This guidance is applicable to us for our fiscal year beginning January 1, 2021. We are currently evaluating the potential impact of this guidance on our consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, which simplifies the accounting for convertible instruments. ASU 2020-06 eliminates certain models that require separate accounting for embedded conversion features, in certain cases. Additionally, among other changes, the guidance eliminates certain of the conditions for equity classification for contracts in an entity’s own equity. ASU 2020-06 also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and include the effect of share settlement for instruments that may be settled in cash or shares, except for certain liability-classified share-based payment awards. ASU 2020-06 is effective for our fiscal year beginning after December 15, 2021, including interim periods within this fiscal year. Early adoption is permitted, but no earlier than our fiscal year beginning after December 15, 2020, including interim periods within those fiscal years. This guidance can be applied using either a modified or full retrospective approach. We expect to early adopt this guidance on January 1, 2021 on a modified retrospective basis. We expect our total remaining interest expense over the contractual terms of our convertible debt to be approximately $20,000 less than under the existing accounting standards. Adoption is expected to result in an approximate $21,700 decrease in additional paid in capital from the derecognition of the bifurcated equity component, $20,000 increase in debt from the derecognition of the discount associated with the bifurcated equity component and $1,700 decrease to the opening balance of accumulated deficit, representing the cumulative interest expense recognized related to the amortization of the bifurcated conversion option. We expect to write-off the related deferred tax liabilities with a corresponding adjustment to the valuation allowance, resulting in no net tax impact to the cumulative adjustment to retained earnings. Significant Accounting Policies Revenue Recognition Revenues are recognized when control of the promised goods or services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Our customers generally execute contracts with terms of one year or longer, which are referred to as recurring revenue contracts or long-term contracts. These contracts generally allow the customer access to our network and are either entirely usage based or commit the customer to a minimum monthly level of usage with additional charges applicable for actual usage above the monthly minimum commitment. We define usage as customer data sent or received using our content delivery service, or content that is hosted or cached by us at the request or direction of our customers. For contracts that contain minimum monthly commitments, we recognize revenue equal to the greater of the minimum monthly committed amount or actual usage, if actual usage exceeds the monthly committed amount, using the right to invoice practical expedient allowable under Topic 606. For contracts that contain minimum commitments over a term greater than one month, we estimate an amount of variable consideration by using the expected value method. We include estimates of variable consideration in revenue only when we have a high degree of confidence that revenue will not be reversed in a subsequent reporting period. We believe that the expected value method is the most appropriate estimate of the amount of variable consideration. These customers have entered into contracts with contract terms generally from one We may charge the customer an activation fee when services are first activated. We do not charge activation fees for contract renewals. Activation fees are not distinct within the context of the overall contractual commitment with the customer to perform our content delivery service and are therefore recorded initially as deferred revenue and recognized as revenue ratably over the estimated life of the customer arrangement. We also derive revenue from services and events sold as discrete, non-recurring events or based solely on usage. For these services, we recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. At the inception of a customer contract for service, we make an assessment as to that customer’s ability to pay for the services provided. If we subsequently determine that collection from the customer is not probable, we record an allowance for credit losses or deferred revenue for that customer’s unpaid invoices and cease recognizing revenue for continued services provided until it is probable that revenue will not be reversed in a subsequent reporting period. Our standard payment terms vary by the type and location of our customer but do not contain a financing component. Arrangements with Multiple Performance Obligations Certain of our revenue arrangements include multiple promises to our customers. Revenue arrangements with multiple promises are accounted for as separate performance obligations if each promise is distinct. Such arrangements may include a combination of some or all of the following: content delivery services, video content management services, performance services for website and web application acceleration and security, professional services, cloud storage, edge computing services, and sale of equipment. Judgment may be required in determining whether products or services are considered distinct performance obligations that should be accounted for separately or as one combined performance obligation. Revenue is recognized over the period in which the performance obligations are satisfied, which is generally over the contract term. We have determined that generally most of our products and services do not constitute an individual service offering to our customers, as our promise to the customer is to provide a complete edge services platform, and therefore have concluded that it represents a single performance obligation. We have determined that professional services and hardware sales represent separate performance obligations from that of our edge services platform. Consideration is allocated to the performance obligations using the relative standalone selling price method. Generally, arrangements with multiple performance obligations are provided over the same contract period, and therefore, revenue is recognized over the same period. We determine standalone selling price by evaluating the overall pricing objectives and market conditions. Consideration included our discounting practices, the size and volume of our transactions, the area where services are sold, price lists, historical sales and contract prices. Deferred Revenue Deferred revenue represents amounts billed to customers for which revenue has not been recognized. Deferred revenue primarily consists of the unearned portion of monthly billed service fees, implementation fees, and prepayments made by customers for services to be rendered in future periods. Convertible Senior Notes In July 2020, we issued $125,000 aggregate principal amount of 3.50% convertible senior notes. We separate our convertible senior notes (the Notes) into liability and equity components. The carrying amount of the liability component is calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component representing the conversion option is determined by deducting the fair value of the liability component from the principal amount of the Notes. The excess of the principal amount of the Notes over the carrying amount of the liability component (debt discount) is amortized to interest expense at an effective interest rate over the contractual term of the Notes. The equity component is recorded in additional paid-in capital and is not remeasured as long as it continues to meet the conditions for equity classification. We allocate the issuance costs to the liability and equity components of the Notes based on the proportion of the proceeds allocated to the debt and equity components. Issuance costs attributable to the liability component are amortized to interest expense using the effective interest method over the contractual terms of the Notes. Issuance costs attributable to the equity component are netted with the equity component in stockholders’ equity. Cash and Cash Equivalents We hold our cash and cash equivalents in checking, money market, and highly-liquid investments. We consider all highly liquid investments with maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents are deposited in or managed by major financial institutions and at times exceed Federal Deposit Insurance Corporation insurance limits. Investments in Marketable Securities We hold investments in marketable securities, consisting of municipal bonds, investment grade corporate debt securities, and certificates of deposit. Management determines the appropriate classification of its marketable securities at the time of purchase and reevaluates such classification as of each balance sheet date. We have classified our investments, which are all debt securities, in marketable securities as available-for-sale and as current, as our marketable securities are available to fund current operations. Our available-for-sale investments are carried at estimated fair value with any unrealized gains and losses, net of taxes, included in accumulated other comprehensive income (loss) in stockholders' equity. Available-for-sale debt securities with an amortized cost basis in excess of estimated fair value are assessed to determine what amount of that difference, if any, is caused by expected credit losses. Expected credit losses on available-for-sale debt securities are recognized in other income (expense), net on our condensed consolidated statements of operations, and any remaining unrealized losses, net of taxes, are included in accumulated other comprehensive income (loss) in stockholders' equity. Credit losses on our marketable securities portfolio for the year ended December 31, 2020 were not material. We determine realized gains or losses on sale of marketable securities on a specific identification method and record such gains or losses as interest and other income (expense), net. Accounts Receivable Trade accounts receivable are recorded at the invoiced amounts and do not bear interest. We record reserves against our accounts receivable balance for service credits and for doubtful accounts. Estimates are used in determining both of these reserves. The allowance for credit losses are included as a component of general and administrative expenses. All trade receivables are reported on the Consolidated Balance Sheets at their amortized cost adjusted for any write-offs and net of allowances for credit losses. We maintain an allowance for credit losses, which represents an estimate of expected losses of our receivables considering current market conditions and estimates for supportable forecasts when appropriate. The estimate is a result of our ongoing assessments and evaluations of collectability, historical loss experience, and future expectations in estimating credit losses for our trade receivables. For trade receivables, we apply a reserve percentage to the specific age of the receivable to estimate the allowance for doubtful accounts. The reserve percentages are determined based on our historical write-off experience. Determination of the proper amount of allowance requires management to exercise judgment about the timing, frequency and severity of potential credit losses that could materially affect the provision for credit losses and, as a result, net earnings. The allowance takes into consideration numerous quantitative and qualitative factors that include receivable type, historical loss experience, delinquency trends, collection experience, current economic conditions, estimates for supportable forecasts, when appropriate, and credit risk characteristics. Our reserve for service credits relates to credits that are expected to be issued to customers during the ordinary course of business. These credits typically relate to customer disputes and billing adjustments and are estimated at the time the revenue is recognized and recorded as a reduction of revenues. Estimates for service credits are based on an analysis of credits issued in previous periods. We evaluate the credit risk of the customer when extending credit based on a combination of various financial and qualitative factors that may affect our customers’ ability to pay. These factors may include the customer’s financial condition, past payment experience, and credit bureau information. Property and Equipment Property and equipment are carried at cost less accumulated depreciation or amortization. Depreciation and amortization are computed using the straight-line method over the assets’ estimated useful lives of the applicable asset. Network equipment 3 years Computer equipment and software 3 years Furniture and fixtures 3-5 years Other equipment 3-5 years Leasehold improvements are amortized over the shorter of the asset’s estimated useful life or the respective lease term. Repairs and maintenance are charged to expense as incurred. Goodwill and Other Intangible Assets Goodwill represents costs in excess of fair values assigned to the underlying net assets of the acquired company. Goodwill is not amortized but instead is tested for impairment annually or more frequently if events or changes in circumstances indicate goodwill might be impaired. We have concluded that we have one reporting unit and assigned the entire balance of goodwill to this reporting unit. The estimated fair value of the reporting unit is determined using a market approach. Our market capitalization is adjusted for a control premium based on the estimated average and median control premiums of transactions involving companies comparable to us. As of our annual impairment testing date of October 31, 2020, management determined that goodwill was not impaired. Contingencies We record contingent liabilities resulting from asserted and unasserted claims when it is probable that a loss has been incurred and the amount of the loss is reasonably estimable. We disclose contingent liabilities when there is a reasonable possibility that the ultimate loss will exceed the recorded liability. Additionally, estimating the loss, or range of loss, associated with a contingency requires analysis of multiple factors, and changes in law or other developments may ultimately cause our judgments to change. Therefore, actual losses in any future period are inherently uncertain and may be materially different from our estimate. Long-Lived Assets We review our long-lived assets for impairment annually, or whenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. We recognize an impairment loss if the sum of the expected long-term undiscounted cash flows that the long-lived asset group is expected to generate is less than the carrying amount of the long-lived asset being evaluated. We treat any write-downs as permanent reductions in the carrying amounts of the assets. We concluded that the carrying amounts of our long-lived assets at December 31, 2020, and 2019, are fully realizable and have not recorded any impairment losses. Leases We determine if an arrangement is a lease at inception. Operating leases are included in ROU assets, and lease liability obligations are included in our consolidated balance sheets. ROU assets represent our right to use an underlying asset for the lease term and lease liability obligations represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. We have lease agreements with lease and non-lease components and account for such components as a single lease component. As most of our leases do not provide an implicit rate, we estimated our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The ROU asset also includes any lease payments made and excludes lease incentives and lease direct costs. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease term. Upon review of our co-location and bandwidth arrangements, we have determined that such arrangements did not meet the leasing criteria, and therefore, were not included in our ROU asset and lease liability obligations on our balance sheet. We have determined that our real estate leases with terms in excess of one year and which do not include an option to purchase the underlying asset, do meet the leasing criteria. Please refer to Note 16 "Operating Leases - Right of Use Assets and Purchase Commitments" for additional information. Cost of Revenue Cost of revenues consists primarily of fees paid to network providers for bandwidth and backbone, costs incurred for non-settlement free peering and connection to Internet service provider networks and fees paid to data center operators for housing network equipment in third party network data centers, also known as co-location costs. Cost of revenues also includes leased warehouse space and utilities, depreciation of network equipment used to deliver our content delivery services, payroll and related costs, and share-based compensation for our network operations and professional services personnel. We enter into contracts for bandwidth with third party network providers with terms typically ranging from several months to three years. These contracts generally commit us to pay minimum monthly fees plus additional fees for bandwidth usage above contracted minimums. A portion of the global computing platform traffic delivery is completed through direct connection to ISP networks, called peering. Research and Development Research and development costs consist primarily of payroll and related personnel costs for the design, development, deployment, testing, operation, and enhancement of our services, and network. Costs incurred in the development of our services are expensed as incurred. Advertising Costs Costs associated with advertising are expensed as incurred. Advertising expenses, which are comprised of Internet, trade show, and publications advertising, were approximately $2,228, $2,120, and $2,169 for the years ended December 31, 2020, 2019, and 2018, respectively. Income Taxes We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more likely than not be realized. In making such determination, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax planning strategies, and recent financial performance on a jurisdiction by jurisdiction basis. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we would make an adjustment to the valuation allowance, which would reduce the provision for income taxes. We recognize uncertain income tax positions in our financial statements when it is more-likely-than-not the position will be sustained upon examination. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted in response to the COVID-19 pandemic. The CARES Act, among other things, permits NOL carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. In addition, the CARES Act allows NOLs incurred in 2018, 2019, and 2020 to be carried back to each of the five preceding taxable years to generate a refund of previously paid income taxes. We have evaluated the impact of the CARES Act, and do not expect that the NOL carryback provision of the CARES Act to result in a cash benefit to us. Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents approximate fair value due to the nature and short maturity of those instruments. The respective fair values of marketable securities are determined based on quoted market prices or other readily available market information, which approximate fair values. The carrying amounts of accounts receivable, accounts payable, and accrued liabilities reported in the consolidated balance sheets approximate their respective fair values due to the immediate or short-term maturity of these financial instruments. Share-Based Compensation We account for our share-based compensation awards using the fair-value method. The grant date fair value was determined using the Black-Scholes-Merton pricing model. The Black-Scholes-Merton valuation calculation requires us to make key assumptions such as future stock price volatility, expected terms, risk-free rates, and dividend yield. Our expected volatility is derived from our volatility rate as a publicly traded company. The expected term is based on our historical experience. The risk-free interest factor is based on the United States Treasury yield curve in effect at the time of the grant for zero coupon United States Treasury notes with maturities of approximately equal to each grant’s expected term. We have never paid cash dividends and do not currently intend to pay cash dividends, and therefore, we have assumed a 0% dividend yield. |
