Accounting Policies [Abstract] | |
Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared pursuant to the rules and regulations of the SEC. They do not include all of the information and footnotes required by U.S. generally accepted accounting principles (U.S. GAAP) for complete financial statements. Such interim financial information is unaudited but reflects all adjustments that are, in the opinion of management, necessary for the fair presentation of the interim periods presented and of a normal recurring nature. This quarterly report on Form 10-Q should be read in conjunction with our audited financial statements and footnotes included in our annual report on Form 10-K for the fiscal year ended December 31, 2017. All information is presented in thousands, except per share amounts and where specifically noted. 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 year amounts to conform to the current year 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 quarterly report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2018, or for any future periods. Recent Accounting Standards Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2014-09 (Topic 606) "Revenue from Contracts with Customers." Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) Topic 605 “Revenue Recognition” (Topic 605), and requires entities to recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. We recorded a net decrease to opening accumulated deficit of $1,496 as of January 1, 2018 due to the cumulative impact of adopting Topic 606, with the impact primarily related to the costs to obtain a customer contract ($1,129) , specifically commissions and upfront incentive payments, and from the recognition of revenue from customers with contracts that contain minimum commitments billed ratably over the contract term ($367) . The costs associated with obtaining a customer contract were previously expensed in the period they were incurred. Under Topic 606, these payments have been deferred on our consolidated balance sheets and amortized over the expected life of the customer contract. The impact to sales and marketing expense for the three and nine months ended September 30, 2018 was not material as a result of applying Topic 606. As of September 30, 2018, prepaid commissions were $1,310 , with the short term portion of $767 included in prepaid expenses and other current assets, and the long term portion of $543 included in other assets. For customers with contracts that contain minimum commitments billed ratably over the contract term, previously, we either accrued or deferred revenue based on actual usage. Under Topic 606, we are required to evaluate the impact of estimating variable consideration related to these types of contracts. We use the expected value method to estimate the total revenue of the contract, constrained by the probability that there would not be a significant revenue reversal in a future period, and recognize a pro-rata share of the total revenue of the contract each month. We continue to evaluate the expected value of revenue over the term of the contract and adjust revenue recognition as appropriate. The impact to revenues for the three and nine months ended September 30, 2018 was an increase of $450 and $145 , respectively, as a result of applying Topic 606. 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 commit the customer to a minimum monthly level of usage with additional charges applicable for actual usage above the monthly minimum commitment, or are entirely usage based. 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 the contractual term, we estimate an amount of variable consideration by using either the expected value method or the most likely amount 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 to four years. As of September 30, 2018, we have approximately $6,600 of remaining unsatisfied performance obligations. We recognized revenue of approximately $1,900 and $3,900 during the three and nine months ended September 30, 2018, respectively, related to these types of contracts with our customers. We expect to recognize approximately 25% of the remaining unsatisfied performance obligations in 2018, approximately 55% in 2019 and the remainder in 2020. We may charge the customer an installation fee when services are first activated. We do not charge installation fees for contract renewals. Installation fees are not distinct within the context of the overall contractual commitment with the customer to perform our content delivery service and are therefore recognized 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 doubtful accounts and bad debt expense 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. 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. Consideration is allocated to the performance obligations using the relative standalone selling price method. Generally, arrangements with performance obligations are provided over the same contract period, and therefore, revenue is recognized over the same period. 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 and prepayments made by customers for services to be rendered in future periods. Adopted Accounting Standards - continued In August 2016, the FASB issued ASU No. 2016-15, which amends ASC 230, to clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. The FASB issued ASU 2016-15 with the intent of reducing diversity in practice with respect to eight types of cash flows. This guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We have adopted this guidance effective January 1, 2018. The adoption of this new guidance did not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. We have adopted this guidance effective January 1, 2018. The adoption of this new guidance did not have a material impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, which establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for most leases. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. We are utilizing a comprehensive approach to assess the impact of the guidance on our lease portfolio by reviewing our current accounting policies and practices to identify potential differences that would result from applying the new requirements. We continue to make significant progress on the potential impact on our accounting policies, internal control processes including system readiness and the related disclosures that will be required under the new guidance. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. Early adoption is permitted and should be applied using a modified retrospective approach. We do not plan to early adopt this guidance. We continue to review additional leases to assess the impact under the new guidance, and expect it will result in an increase to total assets and liabilities on our consolidated balance sheet. We expect to utilize the short-term lease recognition and measurement practical expedient, which will lower the overall impact of this guidance on our financial statements. We expect to make an accounting policy election, where leases that are 12 months or less and do not include an option to purchase the underlying asset, will be treated similar to current operating lease accounting. We do not know and cannot reasonably estimate quantitative information related to the impact of the new standard on our financial statements at this time. 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. This guidance will become effective for us in fiscal years beginning after December 15, 2019, including interim periods within that reporting period. We will adopt this guidance using a prospective approach. Earlier adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not plan to early adopt this ASU, and we are currently evaluating the impact of this guidance on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, which simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation-Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. Some of the areas for simplification apply only to nonpublic entities. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this updated guidance are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted. We do not plan to early adopt this ASU. We are currently evaluating the potential impacts of this updated guidance, and do not expect the adoption of this guidance to 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. This guidance will become effective for us in fiscal years beginning after December 15, 2019, including interim periods within that reporting period. Early adoption is permitted upon issuance of this updated guidance. 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 do not plan to early adopt this ASU, and we are currently evaluating the impact of this guidance on our consolidated financial statements. 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 . This guidance will become effective for us in fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact that this guidance will have upon our financial position and results of operations, if any. |

Goodwill and Intangible Assets Disclosure [Abstract] | |
Goodwill | Goodwill We have recorded goodwill as a result of past business acquisitions. Goodwill is recorded when the purchase price paid for an acquisition exceeds the estimated fair value of the net identified tangible and intangible assets acquired. In each of our acquisitions, the objective of the acquisition was to expand our product offerings and customer base and to achieve synergies related to cross selling opportunities, all of which contributed to the recognition of goodwill. No interim indicators of impairment were identified as of September 30, 2018 . Foreign currency translation adjustments increased the carrying amount of goodwill by $ 35 for the three months ended September 30, 2018 . For the nine months ended September 30, 2018 , foreign currency translation adjustments decreased the carrying value of goodwill by $ 371 . |

Line of Credit | Line of Credit In February 2018, we entered into a Fourth Amendment (Fourth Amendment) to the Loan and Security Agreement (the Credit Agreement) with Silicon Valley Bank (SVB) originally entered into in November 2015. Under the Fourth Amendment, we increased the maximum principal commitment amount from $10,000 to $20,000 . Our borrowing capacity is the lesser of the commitment amount or 80% of eligible accounts receivable. The Fourth Amendment extends the Credit Agreement one year. All outstanding borrowings owed under the Credit Agreement become due and payable no later than the final maturity date of November 2, 2020. As of September 30, 2018 , we had no outstanding borrowings, and we had availability under the Credit Agreement of approximately $18,300 . We had no outstanding borrowings at December 31, 2017, and we had availability under the Credit Agreement of approximately $10,000 . As of September 30, 2018 , borrowings under the Credit Agreement bear interest at the current prime rate minus 0.25% . In the event of default, obligations shall bear interest at a rate per annum that is 3% above the then applicable rate. We incurred an amendment fee of $50 upon entering into the Fourth Amendment. The amendment fee and other commitment fees are included in interest expense. During the three months ended September 30, 2018 and 2017, there was no interest expense, and fees expense and amortization was $10 and $18 , respectively. For the nine months ended September 30, 2018 and 2017, there was no interest expense, and fees expense and related amortization was $76 and $42 , respectively. Any borrowings are secured by essentially all of our domestic personal property, with a negative pledge on intellectual property. SVB’s security interest in our foreign subsidiaries is limited to 65% of voting stock of each such foreign subsidiary. Under the Fourth Amendment, we are required to maintain a minimum liquidity of $10,000 at all times, measured quarterly, with a minimum of $5,000 of the $10,000 in cash at SVB. In addition, we are required to maintain an Adjusted Quick Ratio of at least 1.0 to 1.0. We are also subject to certain customary limitations on our ability to, among other things, incur debt, grant liens, make acquisitions and other investments, make certain restricted payments such as dividends, dispose of assets or undergo a change in control. As of September 30, 2018 , we were in compliance with all covenants under the Credit Agreement. |

Contingencies | Contingencies Legal Matters Akamai ‘703 Litigation In June 2006, Akamai Technologies, Inc. (Akamai) and the Massachusetts Institute of Technology (MIT) filed a lawsuit against us in the United States District Court for the District of Massachusetts alleging that we were infringing multiple patents assigned to MIT and exclusively licensed by MIT to Akamai. In August 2016, we entered into a settlement and license agreement with Akamai with respect to U.S. Patent No. 6,108,703 (the ’703 patent) and certain other related patents, which settled all asserted and unasserted claims with respect to the licensed patents. The terms of the agreement require us to pay $54,000 over twelve equal quarterly installments, which began on August 1, 2016. We recorded a charge in the quarter ended June 30, 2016 for the full, undiscounted amount of $54,000 . As of September 30, 2018 , there remained $13,500 due to Akamai under the terms of the settlement and license agreement. Other Akamai Litigation In November 2015, we filed a lawsuit against Akamai and XO Communications in the District Court for the Eastern District of Virginia alleging the infringement of six of our patents covering a broad range of inventions that we believe are critical to the effective and efficient delivery of bytes by a content delivery network (the Akamai and XO Litigation). Akamai also filed counterclaims in April 2016, alleging the infringement of five of its patents. We filed an answer to Akamai’s counterclaims, denying each of the allegations of infringement in May 2016. In February 2016, Akamai filed a complaint against us in the District Court for the District of Massachusetts alleging infringement of three of its patents. In April 2016, Akamai amended its complaint by withdrawing one of the asserted patents. In April 2016, we filed our answer to the complaint, denying each of the allegations of infringement, and asserting two counterclaims alleging infringement of two of our patents. In December 2016, Akamai filed a second complaint against us in the District Court for the District of Massachusetts alleging infringement of three additional patents, and we later filed our answer to the complaint, denying each of the allegations of infringement. The two cases were ultimately consolidated into a single action by the court. On April 9, 2018, we entered into a definitive settlement and patent license agreement where the parties agreed to (i) license certain patents to the other party, (ii) a covenant not to sue for three years for certain patents related to the licensed patents, and (iii) settle all outstanding legal disputes between the parties. The terms of the agreement also require Akamai to pay to Limelight a total of $14,900 over five equal quarterly installments. The second quarterly payment of $2,980 was received in July 2018. We include litigation expenses in general and administrative expenses as incurred, as reported in the consolidated statement of operations. Other Matters We are subject to various other legal proceedings and claims, either asserted or unasserted, arising in the ordinary course of business. While the outcome of these claims cannot be predicted with certainty, management does not believe the outcome of any of these matters will have a material adverse effect on our business, financial position, results of operations, or cash flows. Litigation relating to the content delivery services industry is not uncommon, and we are, and from time to time have been, subject to such litigation. No assurances can be given with respect to the extent or outcome of any such litigation in the future. Taxes We are subject to indirect taxation in various states and foreign jurisdictions. Laws and regulations that apply to communications and commerce conducted over the Internet are becoming more prevalent, both in the United States and internationally, and may impose additional burdens on us conducting business online or providing Internet-related services. Increased regulation could negatively affect our business directly, as well as the businesses of our customers, which could reduce their demand for our services. For example, tax authorities in various states and abroad may impose taxes on the Internet-related revenue we generate based on regulations currently being applied to similar but not directly comparable industries. There are many transactions and calculations where the ultimate tax determination is uncertain. In addition, domestic and international taxation laws are subject to change. In the future, we may come under audit, which could result in changes to our tax estimates. We believe we maintain adequate tax reserves, that are not material in amount, to offset potential liabilities that may arise upon audit. Although we believe our tax estimates and associated reserves are reasonable, the final determination of tax audits and any related litigation could be materially different than the amounts established for tax contingencies. To the extent these estimates ultimately prove to be inaccurate, the associated reserves would be adjusted, resulting in the recording of a benefit or expense in the period in which a change in estimate or a final determination is made. |

Earnings Per Share [Abstract] | |
Net Loss per Share | Net Income (Loss) per Share We calculate basic and diluted income (loss) per weighted average share. We use the weighted-average number of shares of common stock outstanding during the period for the computation of basic income (loss) per share. Diluted income (loss) per share include the dilutive effect of all potentially dilutive common stock, including awards granted under our equity incentive compensation plans in the weighted-average number of shares of common stock outstanding. The following table sets forth the components used in the computation of basic and diluted net income (loss) per share for the periods indicated: Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Net (loss) income $ (272 ) $ (1,756 ) $ 15,035 $ (6,718 ) Basic weighted average outstanding shares of common stock 112,760 109,342 111,626 108,376 Basic weighted average outstanding shares of common stock 112,760 109,342 111,626 108,376 Dilutive effect of stock options, restricted stock units, and other equity incentive plans — — 8,399 — Diluted weighted average outstanding shares of common stock 112,760 109,342 120,025 108,376 Basic net income (loss) per share $ — $ (0.02 ) $ 0.13 $ (0.06 ) Diluted net income (loss) per share: $ — $ (0.02 ) $ 0.13 $ (0.06 ) For the three and nine months ended September 30, 2018 and 2017 , respectively, the following potentially dilutive common stock, including awards granted under our equity incentive compensation plans, were excluded from the computation of diluted net loss per share because including them would have been anti-dilutive.

Any shares repurchased under this program will be canceled and returned to authorized but unissued status. This share repurchase program replaced the $9,500 remaining from the previously announced $15,000 share repurchase program. During the three months ended September 30, 2018 , we did no t repurchase any shares under the repurchase program. During the nine months ended September 30, 2018, we purchased and canceled 1,000 shares for $3,800 , including commissions and fees.

Amended and Restated Equity Incentive Plan We established the 2007 Equity Incentive Plan, or the 2007 Plan, which allows for the grant of equity, including stock options and restricted stock unit awards. In June 2016, our stockholders approved the Amended and Restated Equity Incentive Plan, or the Restated 2007 Plan, which amended and restated the 2007 Plan. Approval of the Restated 2007 Plan replaced the terms and conditions of the 2007 Plan with the terms and conditions of the Restated 2007 Plan, and extended the term of the plan to April 2026. There was no increase in the aggregate amount of shares available for issuance. The total number of shares authorized for issuance under the Restated 2007 Plan as of September 30, 2018 was approximately 10,706 . Employee Stock Purchase Plan In June 2013, our stockholders approved our 2013 Employee Stock Purchase Plan (ESPP). The ESPP allows participants to purchase our common stock at a 15% discount of the lower of the beginning or end of the offering period using the closing price on that day. During the three months ended September 30, 2018, we did no t issue any shares under the ESPP. During the nine months ended September 30, 2018, we issued 250 shares under the ESPP. Total cash proceeds from the purchase of the shares under the ESPP was approximately $1,110 . As of September 30, 2018 , shares reserved for issuance to employees under this plan totaled 380 , and we held employee contributions of $911 (included in other current liabilities) for future purchases under the ESPP.

Income Tax Disclosure [Abstract] | |
Income Taxes | Income Taxes Income taxes for the interim periods presented have been included in the accompanying consolidated financial statements on the basis of an estimated annual effective tax rate. Based on an estimated annual effective tax rate and discrete items, income tax expense for the three months ended September 30, 2018 and 2017, was $ 113 and $188 , respectively. For the nine months ended September 30, 2018 and 2017, income tax expense was $ 347 and $ 448 , respectively. Income tax expense was different than the statutory income tax rate primarily due to us providing for a valuation allowance on deferred tax assets in certain jurisdictions, and the recording of state and foreign tax expense for the three and nine month periods. We file income tax returns in jurisdictions with varying statutes of limitations. Tax years 2014 through 2016 remain subject to examination by federal tax authorities. Tax years 2013 through 2016 generally remain subject to examination by state tax authorities. As of September 30, 2018 , we are not under any federal or state examination for income taxes. On December 22, 2017, the Tax Cuts and Jobs Act (the Tax Act) significantly revised the U.S. corporate income tax law, by among other things, reducing the corporate income tax rate to 21% for tax years beginning in 2018, implementing a modified territorial system that includes a one-time transition tax on deemed repatriated earnings of foreign subsidiaries and creating new taxes on certain foreign sourced earnings. Also on December 22, 2017, The SEC staff issued Staff Accounting Bulletin (SAB) 118 to provide guidance for companies that are not able to complete their accounting for the income tax effects of the Tax Act in the period of enactment. SAB 118 provides for a measurement period of up to one year from the date of enactment. During the measurement period, companies need to reflect adjustments to any provisional amounts if it obtains, prepares or analyzes additional information about facts and circumstances that existed as of the enactment date that, if known, would have affected the income tax effects initially reported as provisional amounts. At September 30, 2018 we have not yet completed our analysis of the Tax Act; however, in certain circumstances, as described below, we have made a reasonable estimate of the effects of the Tax Act. Provisional Amounts Our deferred tax balances for the year ending December 31, 2017 reflected an estimated $41 tax benefit related to the re-measurement of a deferred tax liability on a long-lived asset. The remaining impact from the re-measurement of our net U.S. deferred tax asset at the lower 21% rate was offset by the valuation allowance. Our deferred tax balances for the year ending December 31, 2017 reflected the estimated impact from the one-time transition tax that we previously deferred from U.S. income taxes. The transition tax that we calculated resulted in an immaterial amount of additional federal taxable income. The additional taxable income from the transition tax was offset by net operating losses (NOLs) and did not result in cash taxes payable. There were no changes to the provisional amounts recorded as of December 31, 2017. We will consider the revaluation of our deferred balances and the one-time transition tax amount as provisional amounts until we finalize our analysis. The tax provision incorporates assumptions made based upon the Company’s current interpretation of the Tax Act, and may change as we receive additional clarification and implementation guidance and as the interpretation of the Tax Act evolves over time. The Tax Act contains several base broadening provisions that became effective on January 1, 2018 that we do not expect to have a material impact on future earnings due to our NOL and valuation allowance position. Also effective for 2018 is a new Global Intangible Low-Taxed Income inclusion (GILTI). There was no impact to income tax expense related to the GILTI as a result of our NOL and valuation allowance position. We do not expect the GILTI to have a material impact on future earnings due to our NOL and valuation allowance position. |

This quarterly report on Form 10-Q should be read in conjunction with our audited financial statements and footnotes included in our annual report on Form 10-K for the fiscal year ended December 31, 2017. All information is presented in thousands, except per share amounts and where specifically noted. 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 year amounts to conform to the current year presentation. |
Use of Estimates | 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 quarterly report on Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2018, or for any future periods. |
Recent Accounting Standards | Recent Accounting Standards Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2014-09 (Topic 606) "Revenue from Contracts with Customers." Topic 606 supersedes the revenue recognition requirements in Accounting Standards Codification (ASC) Topic 605 “Revenue Recognition” (Topic 605), and requires entities to recognize revenue when control of promised goods or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. On January 1, 2018, we adopted Topic 606 using the modified retrospective method applied to those contracts which were not completed as of January 1, 2018. Results for reporting periods beginning after January 1, 2018 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historic accounting under Topic 605. We recorded a net decrease to opening accumulated deficit of $1,496 as of January 1, 2018 due to the cumulative impact of adopting Topic 606, with the impact primarily related to the costs to obtain a customer contract ($1,129) , specifically commissions and upfront incentive payments, and from the recognition of revenue from customers with contracts that contain minimum commitments billed ratably over the contract term ($367) . The costs associated with obtaining a customer contract were previously expensed in the period they were incurred. Under Topic 606, these payments have been deferred on our consolidated balance sheets and amortized over the expected life of the customer contract. The impact to sales and marketing expense for the three and nine months ended September 30, 2018 was not material as a result of applying Topic 606. As of September 30, 2018, prepaid commissions were $1,310 , with the short term portion of $767 included in prepaid expenses and other current assets, and the long term portion of $543 included in other assets. For customers with contracts that contain minimum commitments billed ratably over the contract term, previously, we either accrued or deferred revenue based on actual usage. Under Topic 606, we are required to evaluate the impact of estimating variable consideration related to these types of contracts. We use the expected value method to estimate the total revenue of the contract, constrained by the probability that there would not be a significant revenue reversal in a future period, and recognize a pro-rata share of the total revenue of the contract each month. We continue to evaluate the expected value of revenue over the term of the contract and adjust revenue recognition as appropriate. The impact to revenues for the three and nine months ended September 30, 2018 was an increase of $450 and $145 , respectively, as a result of applying Topic 606. 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 commit the customer to a minimum monthly level of usage with additional charges applicable for actual usage above the monthly minimum commitment, or are entirely usage based. 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 the contractual term, we estimate an amount of variable consideration by using either the expected value method or the most likely amount 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 to four years. As of September 30, 2018, we have approximately $6,600 of remaining unsatisfied performance obligations. We recognized revenue of approximately $1,900 and $3,900 during the three and nine months ended September 30, 2018, respectively, related to these types of contracts with our customers. We expect to recognize approximately 25% of the remaining unsatisfied performance obligations in 2018, approximately 55% in 2019 and the remainder in 2020. We may charge the customer an installation fee when services are first activated. We do not charge installation fees for contract renewals. Installation fees are not distinct within the context of the overall contractual commitment with the customer to perform our content delivery service and are therefore recognized 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 doubtful accounts and bad debt expense 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. 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. Consideration is allocated to the performance obligations using the relative standalone selling price method. Generally, arrangements with performance obligations are provided over the same contract period, and therefore, revenue is recognized over the same period. 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 and prepayments made by customers for services to be rendered in future periods. Adopted Accounting Standards - continued In August 2016, the FASB issued ASU No. 2016-15, which amends ASC 230, to clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows. The FASB issued ASU 2016-15 with the intent of reducing diversity in practice with respect to eight types of cash flows. This guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We have adopted this guidance effective January 1, 2018. The adoption of this new guidance did not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. ASU 2017-09 will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. Under ASU 2017-09, an entity will not apply modification accounting to a share-based payment award if the award's fair value, vesting conditions and classification as an equity or liability instrument are the same immediately before and after the change. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. We have adopted this guidance effective January 1, 2018. The adoption of this new guidance did not have a material impact on our consolidated financial statements. Recently Issued Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, which establishes a right-of-use model that requires a lessee to record a right-of-use asset and a lease liability on the balance sheet for most leases. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. We are utilizing a comprehensive approach to assess the impact of the guidance on our lease portfolio by reviewing our current accounting policies and practices to identify potential differences that would result from applying the new requirements. We continue to make significant progress on the potential impact on our accounting policies, internal control processes including system readiness and the related disclosures that will be required under the new guidance. This guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within that reporting period. Early adoption is permitted and should be applied using a modified retrospective approach. We do not plan to early adopt this guidance. We continue to review additional leases to assess the impact under the new guidance, and expect it will result in an increase to total assets and liabilities on our consolidated balance sheet. We expect to utilize the short-term lease recognition and measurement practical expedient, which will lower the overall impact of this guidance on our financial statements. We expect to make an accounting policy election, where leases that are 12 months or less and do not include an option to purchase the underlying asset, will be treated similar to current operating lease accounting. We do not know and cannot reasonably estimate quantitative information related to the impact of the new standard on our financial statements at this time. 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. This guidance will become effective for us in fiscal years beginning after December 15, 2019, including interim periods within that reporting period. We will adopt this guidance using a prospective approach. Earlier adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. We do not plan to early adopt this ASU, and we are currently evaluating the impact of this guidance on our consolidated financial statements. In June 2018, the FASB issued ASU 2018-07, which simplifies several aspects of the accounting for nonemployee share-based payment transactions resulting from expanding the scope of Topic 718, Compensation-Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. Some of the areas for simplification apply only to nonpublic entities. The amendments specify that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. The amendments also clarify that Topic 718 does not apply to share-based payments used to effectively provide (1) financing to the issuer or (2) awards granted in conjunction with selling goods or services to customers as part of a contract accounted for under Topic 606, Revenue from Contracts with Customers. The amendments in this updated guidance are effective for public business entities for fiscal years beginning after December 15, 2018, including interim periods within that fiscal year. Early adoption is permitted. We do not plan to early adopt this ASU. We are currently evaluating the potential impacts of this updated guidance, and do not expect the adoption of this guidance to 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. This guidance will become effective for us in fiscal years beginning after December 15, 2019, including interim periods within that reporting period. Early adoption is permitted upon issuance of this updated guidance. 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 do not plan to early adopt this ASU, and we are currently evaluating the impact of this guidance on our consolidated financial statements. 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 . This guidance will become effective for us in fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in any interim period. We are currently evaluating the impact that this guidance will have upon our financial position and results of operations, if any. |
