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, 2018. 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, 2019, or for any future periods. Recent Accounting Standards Adopted Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, which establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for most leases. In July 2018, the FASB issued ASU No. 2018-11, which amends the guidance to add a method of adoption whereby the issuer may elect to recognize a cumulative effect adjustment at the beginning of the period of adoption. ASU No. 2018-11 does not require comparative period financial information to be adjusted. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. To determine whether a contract conveys the right to control the use of the identified asset for a period of time, the customer has to have both (1) the right to obtain substantially all of the economic benefits from the use of the identified asset and (2) the right to direct the use of the identified asset, a contract does not contain an identified asset if the supplier has a substantive right to substitute such asset ("the leasing criteria"). 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. On January 1, 2019, we adopted ASU No. 2016-02, applying the package of practical expedients to leases that commenced before the effective date whereby we elected to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. We elected to apply the transition provisions as of January 1, 2019, the date of adoption, and we recorded lease ROU assets and related liabilities on our balance sheet of $3.6 million related to our operating leases. We have no financing leases. There was no change to our consolidated statements of operations or cash flows. 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. 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. We adopted this guidance effective January 1, 2019. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, which requires measurement and recognition of expected credit losses for financial assets held. This guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. 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 do not plan to early adopt this ASU. We are in the process of evaluating the potential impact of adopting this new accounting standard on our consolidated financial statements and related disclosures. 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 accounting standard, and we are currently evaluating the impact of this guidance on our consolidated financial statements. 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 accounting standard, 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 do not plan to early adopt this accounting standard, and we are currently evaluating the impact of this guidance on our consolidated financial statements. 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 March 31, 2019, we have approximately $7,800 of remaining unsatisfied performance obligations. We recognized revenue of approximately $2,700 and $1,000 , respectively, during the three months ended March 31, 2019 and 2018, related to these types of contracts with our customers. We expect to recognize approximately 75% of the remaining unsatisfied performance obligations in 2019, approximately 20% in 2020 and the remaining in 2021. 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. Leases We determine if an arrangement is a lease at inception. Operating leases are included in ROU assets, and lease liability obligations 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. Please refer to Note 16 for additional information. 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. We develop an estimate of the number of share-based awards that will be forfeited due to employee turnover. We will continue to use judgment in evaluating the expected term, volatility, and forfeiture rate related to our own share-based awards on a prospective basis, and in incorporating these factors into the model. If our actual experience differs significantly from the assumptions used to compute our share-based compensation cost, or if different assumptions had been used, we may have recorded too much or too little share-based compensation cost. We apply the straight-line attribution method to recognize compensation costs associated with awards that are not subject to graded vesting. For awards that are subject to graded vesting and performance based awards, we recognize compensation costs separately for each vesting tranche. We also estimate when and if performance-based awards will be earned. If an award is not considered probable of being earned, no amount of share-based compensation is recognized. If the award is deemed probable of being earned, related compensation expense is recorded over the estimated service period. To the extent our estimates of awards considered probable of being earned changes, the amount of share-based compensation recognized will also change. |

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 indicators of impairment were identified as of March 31, 2019 .

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 to $20,000 . Our borrowing capacity is the lesser of the commitment amount or 80% of eligible accounts receivable. 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 March 31, 2019 , we had no outstanding borrowings, and we had availability under the Credit Agreement of approximately $20,000 . We had no outstanding borrowings at December 31, 2018, and we had availability under the Credit Agreement of approximately $20,000 . As of March 31, 2019 , 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. Amendment fees and other commitment fees are included in interest expense. During the three months ended March 31, 2019 and 2018, there was no interest expense, and fees expense and amortization was $10 and $59 , 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. 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 March 31, 2019 , we were in compliance with all covenants under the Credit Agreement. |

Commitments and Contingencies Disclosure [Abstract] | |
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 March 31, 2019 , there remained $4,500 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. As of March 31, 2019, there remained $2,980 due from Akamai. 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) Income per Share | Net (Loss) Income per Share We calculate basic and diluted (loss) income per weighted average share. We use the weighted-average number of shares of common stock outstanding during the period for the computation of basic (loss) income per share. Diluted (loss) income 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 (loss) income per share for the periods indicated (in thousands, except per share data): Three Months Ended March 31, 2019 2018 Net (loss) income $ (8,559 ) $ 149 Basic weighted average outstanding shares of common stock 114,410 110,761 Basic weighted average outstanding shares of common stock 114,410 110,761 Dilutive effect of stock options, restricted stock units, and other equity incentive plans — 8,148 Diluted weighted average outstanding shares of common stock 114,410 118,909 Basic net (loss) income per share $ (0.07 ) $ — Diluted net (loss) income per share: $ (0.07 ) $ — For the three months ended March 31, 2019 and 2018 , 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) income per share because including them would have been anti-dilutive.

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 March 31, 2019 was approximately 10,303 . 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 March 31, 2019, we did no t issue any shares under the ESPP. As of March 31, 2019 , shares reserved for issuance to employees under this plan totaled 34 , and we held employee contributions of $841 (included in other current liabilities) for future purchases under the ESPP. Preferred Stock Our board of directors has authorized the issuance of up to 7,500 shares of preferred stock at March 31, 2019 . The preferred stock may be issued in one or more series pursuant to a resolution or resolutions providing for such issuance duly adopted by the board of directors.

We currently expect to recognize share-based compensation expense of $9,053 during the remainder of 2019, $8,349 in 2020 and the remainder thereafter based on scheduled vesting of the stock options and restricted stock units outstanding at March 31, 2019 . On February 1, 2019, the compensation committee of our board of directors approved a stock for salary program wherein eligible participants elected to receive payment of his or her base salary in shares of our common stock beginning on February 1, 2019. The shares of common stock will be issued under our Amended and Restated 2007 Equity Incentive Plan. Eligible program participants include our Chief Executive Officer and his direct reports. The stock for salary program permits eligible participants to receive 0 , 25 , 50 , 75 , or 100% of his or her 2019 salary (including any increases that may occur during the year) in shares of our common stock. On the last trading day of each calendar month, each participant will receive the number of shares of our common stock determined by dividing (i) 1/12th of his or her enrolled salary by (ii) the trailing 30-day closing average of our common stock, rounded up to the nearest whole share. Once an election is made, it runs for the full year 2019 and is irrevocable and the program will automatically terminate on the earlier to occur of January 1, 2020 or the date upon which Limelight's common stock trades on the Nasdaq at $4.00 per share or greater. Participation levels may not be changed after the close of the enrollment period. Once purchased, there is no vesting period for the shares. During 2019, our Chief Executive Officer and two of his direct reports have elected to participate in the program. Each of the three participants elected to receive 50% of their respective salary in stock. As a result of their participation in the program, we will issue 33 shares of common stock and recorded $101 of share based compensation expense during the three months ended March 31, 2019. |

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 (benefit) for the three months ended March 31, 2019 and 2018, was $ 124 and $(15) , respectively. Income tax expense (benefit) 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 month periods. We file income tax returns in jurisdictions with varying statutes of limitations. Tax years 2015 through 2018 remain subject to examination by federal tax authorities. Tax years 2014 through 2018 generally remain subject to examination by state tax authorities. As of March 31, 2019 , we are not under any federal or state examination for income taxes. For the three months ended March 31, 2019, there was no impact to income tax expense related to the Global Intangible Low-Taxed Income inclusion (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. |

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, 2018. All information is presented in thousands, except per share amounts and where specifically noted.

Recent Accounting Standards | Recent Accounting Standards Adopted Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, which establishes a right-of-use (ROU) model that requires a lessee to record a ROU asset and a lease liability on the balance sheet for most leases. In July 2018, the FASB issued ASU No. 2018-11, which amends the guidance to add a method of adoption whereby the issuer may elect to recognize a cumulative effect adjustment at the beginning of the period of adoption. ASU No. 2018-11 does not require comparative period financial information to be adjusted. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the income statement. ASU 2016-02 defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. To determine whether a contract conveys the right to control the use of the identified asset for a period of time, the customer has to have both (1) the right to obtain substantially all of the economic benefits from the use of the identified asset and (2) the right to direct the use of the identified asset, a contract does not contain an identified asset if the supplier has a substantive right to substitute such asset ("the leasing criteria"). 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. On January 1, 2019, we adopted ASU No. 2016-02, applying the package of practical expedients to leases that commenced before the effective date whereby we elected to not reassess the following: (i) whether any expired or existing contracts contain leases; (ii) the lease classification for any expired or existing leases; and (iii) initial direct costs for any existing leases. We elected to apply the transition provisions as of January 1, 2019, the date of adoption, and we recorded lease ROU assets and related liabilities on our balance sheet of $3.6 million related to our operating leases. We have no financing leases. There was no change to our consolidated statements of operations or cash flows. 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. 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. We adopted this guidance effective January 1, 2019. The adoption of this guidance did not have a material impact on our consolidated financial statements and related disclosures. Recently Issued Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, which requires measurement and recognition of expected credit losses for financial assets held. This guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. 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 do not plan to early adopt this ASU. We are in the process of evaluating the potential impact of adopting this new accounting standard on our consolidated financial statements and related disclosures. 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 accounting standard, and we are currently evaluating the impact of this guidance on our consolidated financial statements. 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 accounting standard, 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 do not plan to early adopt this accounting standard, and we are currently evaluating the impact of this guidance on our consolidated financial statements. 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 March 31, 2019, we have approximately $7,800 of remaining unsatisfied performance obligations. We recognized revenue of approximately $2,700 and $1,000 , respectively, during the three months ended March 31, 2019 and 2018, related to these types of contracts with our customers. We expect to recognize approximately 75% of the remaining unsatisfied performance obligations in 2019, approximately 20% in 2020 and the remaining in 2021. 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. Leases We determine if an arrangement is a lease at inception. Operating leases are included in ROU assets, and lease liability obligations 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. Please refer to Note 16 for additional information. 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. We develop an estimate of the number of share-based awards that will be forfeited due to employee turnover. We will continue to use judgment in evaluating the expected term, volatility, and forfeiture rate related to our own share-based awards on a prospective basis, and in incorporating these factors into the model. If our actual experience differs significantly from the assumptions used to compute our share-based compensation cost, or if different assumptions had been used, we may have recorded too much or too little share-based compensation cost. We apply the straight-line attribution method to recognize compensation costs associated with awards that are not subject to graded vesting. For awards that are subject to graded vesting and performance based awards, we recognize compensation costs separately for each vesting tranche. We also estimate when and if performance-based awards will be earned. If an award is not considered probable of being earned, no amount of share-based compensation is recognized. If the award is deemed probable of being earned, related compensation expense is recorded over the estimated service period. To the extent our estimates of awards considered probable of being earned changes, the amount of share-based compensation recognized will also change. |
