Accounting Policies [Abstract] |
Basis of Presentation | Basis of Presentation and Principles of Consolidation The accompanying interim condensed consolidated financial statements and accompanying notes have been prepared in conformity with generally accepted accounting principles in the United States (U.S. GAAP) and applicable regulations of the Securities and Exchange Commission (the SEC) regarding interim financial reporting, and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. The Company’s fiscal year ends on December 31. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable required disclosures and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and the related notes thereto included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2019.
Principles of Consolidation | All intercompany balances and transactions have been eliminated in consolidation.
Fiscal Period | The Company’s fiscal year ends on December 31.
Use of Estimates | Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes to the condensed consolidated financial statements. Such estimates include, but are not limited to, allowance for doubtful accounts, deferred contract acquisitions costs, the period of benefit generated from the Company’s deferred contract acquisition costs, the capitalization and estimated useful life of internal-use software, the assessment of recoverability of intangible assets and their estimated useful lives, useful lives of property and equipment, liability and equity allocation of convertible senior notes, the determination of the incremental borrowing rate used for operating lease liabilities, the valuation and recognition of stock-based compensation expense, uncertain tax positions, and the recognition and measurement of current and deferred income tax assets and liabilities. Management bases these estimates and assumptions on historical experience and on various other assumptions that management believes to be reasonable. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. The Company is not aware of any specific event or circumstance that would require an update to its estimates or assumptions or a revision of the carrying value of its assets or liabilities as of August 10, 2020, the date of issuance of this Quarterly Report on Form 10-Q. These estimates and assumptions may change in the future, however, as new events occur and additional information is obtained. Actual results could differ materially from these estimates.
Operating Leases | Operating Leases The Company enters into operating lease arrangements for real estate assets related to office space and for co-location assets related to space and equipment located in co-location facilities. The Company determines if an arrangement contains a lease at its inception by assessing whether there is an identified asset and whether the arrangement conveys the right to control the use of the identified asset in exchange for consideration. Operating leases are included in operating lease right-of-use assets, operating lease liabilities, and operating lease liabilities, noncurrent in the Company's condensed consolidated balance sheets. Right-of-use assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make payments arising from the lease. The Company's operating lease arrangements contain both lease and non-lease components. Operating lease right-of-use assets and lease liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Lease payments consist of the fixed payments under the arrangement, less any lease incentives such as tenant improvement allowanc es. Variable lease costs, such as lease payments that depend on an index or a rate, are expensed as incurred and not included within the calculation of right-of-use assets and lease liabilities. At inception of an arrangement, the Company allocates the consideration to the lease and non-lease components and recognizes a right-of-use asset and corresponding lease liability for each lease component. As the implicit rate of the Company's leases is not determinable, the Company uses an incremental borrowing rate (IBR) based on the information available at the lease commencement date in determining the present value of lease payments. The lease expense is recognized on a straight-line basis over the lease term. The Company generally uses the base, non-cancelable lease term when recognizing the right-of-use assets and lease liabilities, unless it is reasonably certain that a renewal or termination option will be exercised. Leases with a term of twelve months or less are not recognized on the consolidated balance sheets. The Company recognizes lease expense for these leases on a straight-line basis over the term of the lease.
Business Combinations | Business Combinations The Company includes the results of operations of the businesses that the Company acquires from the date of acquisition. The fair value of the assets acquired and liabilities assumed is based on their estimated fair values as of the respective date of acquisition. The excess purchase price over the fair value of the net assets acquired and liabilities assumed is recorded as goodwill. Determining the fair value of assets acquired and liabilities assumed requires significant judgment and estimates including the selection of valuation methodologies, future expected cash flows, discount rates, and useful lives. The Company’s estimates of fair value are based on assumptions believed to be reasonable, but which are inherently uncertain and, as a result, actual results may differ from estimates. During the measurement period, not to exceed one year from the date of acquisition, the Company may record adjustments to the assets acquired and liabilities assumed with a corresponding offset to goodwill. At the conclusion of the measurement period, or final determination of the values of assets acquired or liabilities assumed, whichever comes first, any subsequent adjustments are reflected in the condensed consolidated statements of operations. When the Company issues payments or grants of equity to selling stockholders in connection with an acquisition, the Company evaluates whether the payments or awards are compensatory. This evaluation includes whether cash payments or stock award vesting is contingent on the continued employment of the selling stockholder beyond the acquisition date. If continued employment is required for the cash to be paid or stock awards to vest, the award is treated as compensation for post-acquisition services and is recognized as compensation expense. Transaction costs associated with business combinations are expensed as incurred and are included in general and administrative expense in the Company’s condensed consolidated statements of operations.
Convertible Senior Notes | Convertible Senior Notes The Company accounts for its 0.75% Convertible Senior Notes due May 2025 (the Notes) as separate liability and equity components. The carrying amount of the liability component is calculated by measuring the fair value of a similar debt instrument that does not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, is calculated by deducting the fair value of the liability component from the total principal of the convertible notes. The excess of the principal amount of the liability component over its book value (debt discount) is amortized to interest expense over the term of the Notes. In accounting for the issuance costs related to the Notes, the allocation of issuance costs incurred between the liability and equity components was based on their relative values.
Recent Accounting Pronouncements | Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-02, Leases (Topic 842), and since that date, has issued several ASUs to further clarify certain aspects of ASU 2016-02 and provide entities with practical expedients that may be elected upon adoption. The Company adopted the new standard beginning January 1, 2020 using the modified retrospective approach, electing the optional transition approach of not adjusting the comparative period financial statements for the impact of adoption. The Company elected the package of practical expedients permitted under the transition guidance, which allows the Company to carryforward its historical lease classification, its assessment on whether a contract is or contains a lease, and its initial direct costs for any leases that existed prior to adoption of the new standard. In addition, the Company elected not to recognize lease liabilities and related right-of-use assets for leases that, at the lease commencement date, have a lease term of 12 months or less. Adoption of the new standard on January 1, 2020 resulted in the recognition of $50.0 million of operating lease right-of-use assets and $52.8 million of t otal operating lease liabilities o n the Company's condensed consolidated balance sheets. As part of the adoption, the Company also derecognized deferred rent of $2.8 million, primarily consisting of the noncurrent portion, net build-to-suit assets of $9.9 million, the build-to-suit lease financing obligation of $10.5 million, and recorded a cumulative-effect adjustment of $0.6 million to accumulated deficit as of January 1, 2020. Refer to Note 6 to these condensed consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326), Measurement of Credit Losses on Financial Instruments. This ASU changes the methodology for measuring credit losses and requires the establishment of an allowance for estimated credit losses on financial assets, including trade and other receivables, at each reporting date. The Company adopted ASU 2016-13 effective January 1, 2020, noting no material impact on the Company’s condensed consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (ASC 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement. This guidance provides that implementation costs be evaluated for capitalization using the same criteria as that used for internal-use software development costs, with amortization expense being recorded in the same income statement expense line as the hosted service costs and over the expected term of the hosting arrangement. For public business entities, it is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. For all other entities, it is effective for fiscal years beginning after December 15, 2020, and interim periods beginning after December 15, 2021. Early adoption of the amendments in this update is permitted, including adoption in any interim period, for all entities. The Company adopted ASU 2018-15 effective January 1, 2020, noting no material impact on the Company’s condensed consolidated financial statements. In November 2019, the FASB issued ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842). This ASU revises, and staggers, the effective dates for various major updates that have been issued since 2014 to alleviate the burden on both larger public companies as well as private companies, smaller public companies, not-for-profit organizations, and employee benefit plans. The Company adopted ASU 2019-10 effective January 1, 2020, noting no material impact on the Company’s condensed consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (ASC Topic 740). This ASU simplifies accounting for income taxes by removing certain exceptions to the general principles and amending existing guidance to improve consistent application. The amendments in this update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020, with early adoption permitted. The Company adopted ASU 2019-12 effective January 1, 2020, noting no material impact on the Company’s condensed consolidated financial statements. Recently Issued Accounting Pronouncements There have been no recent accounting pronouncements since the filing of the Company's Annual Report on Form 10-K for the year ended December 31, 2019, that may have a material impact on the Company's condensed consolidated financial statements.
Revenue | In accordance with ASC 606, revenue is recognized when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration that the Company expects to be entitled to receive in exchange for these services. To achieve this standard, the Company applies the following five steps: 1. Identify the contract with a customer The Company considers the terms and conditions of the contracts and its customary business practices in identifying its contracts under ASC 606. The Company determines it has a contract with a customer when the contract is approved, the Company can identify each party’s rights regarding the services to be transferred, the Company can identify the payment terms, the Company has determined that collectibility is probable, and the contract has commercial substance. The Company applies judgment in determining that collectibility is probable, which is based on a variety of factors, including the customer’s historical payment experience or, in the case of a new customer, credit and financial information relevant to the customer. 2. Identify the performance obligations in the contract Performance obligations promised in a contract are identified based on the services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the service either on its own or together with other resources that are readily available to the Company, and are distinct in the context of the contract, whereby the transfer of the services is separately identifiable from other promises in the contract. The Company’s performance obligation primarily consists of subscription and support services, as they are provided over the same service period. 3. Determine the transaction price The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring services to the customer. Usage-based variable consideration is recognized in the period it is incurred. None of the Company’s contracts contain a significant financing component. 4. Allocate the transaction price to performance obligations in the contract The subscription and support services in the Company’s contracts are considered a single performance obligation, and thus the entire transaction price is allocated to the single performance obligation. 5. Recognize revenue when or as the Company satisfies a performance obligation Revenue is recognized at the time the related performance obligation is satisfied by transferring the service to a customer. Revenue is recognized when control of the services is transferred to the Company’s customers, in an amount that reflects the consideration that the Company expects to be entitled to receive in exchange for those services. The Company generates sales directly through its sales team and through its channel partners. Revenue from sales to channel partners are recorded once all revenue recognition criteria above are met. Channel partners generally receive an order from an end-customer prior to placing an order with the Company. Payment from channel partners is not contingent on the partner’s collection from end-customers. The Company has determined that it is acting as an agent in these arrangements and records this revenue on a net basis. Subscription and Support Revenue The Company generates revenue primarily from sales to its customers of subscriptions to access its platform, together with related support services. Arrangements with customers generally do not provide the customer with the right to take possession of the Company’s software operating its global cloud platform at any time. Instead, customers are granted continuous access to the Company’s global cloud platform over the contractual period. Access to the Company’s platform and products is considered a monthly series comprising one performance obligation. A time-elapsed output method is used to measure progress because the Company transfers control evenly over the contractual period. Accordingly, the fixed consideration related to subscription and support revenue is generally recognized on a straight-line basis over the contract term beginning on the date that the Company’s service is made available to the customer. Usage-based consideration is primarily related to fees charged for the Company’s customer’s use of excess bandwidth when accessing the Company’s platform in a given period and is recognized as revenue in the period in which the usage occurs. The typical subscription and support term for the Company’s contracted customers, which consist of customers that enter into contracts for the Company's Enterprise subscription plan (and which the Company previously referred to as enterprise customers), is one year and subscription and support term lengths range from one to three years. Most of the Company’s contracts with contracted customers are non-cancelable over the contractual term. Customers typically have the right to terminate their contracts for cause if the Company fails to perform in accordance with the contractual terms. For the Company’s pay-as-you-go customers, which consist of customers that sign up for the Company's Pro or Business subscription plans through the Company's website (and which the Company previously referred to as self-serve customers), subscription and support terms are typically monthly. Variable Consideration If the Company’s services do not meet certain service level commitments, its customers are entitled to receive service credits, and in certain cases, refunds, each representing a form of variable consideration. Revenue from sales is recorded at the net sales price, which is the transaction price, and includes estimates of these forms of variable consideration to the extent that a significant reversal of cumulative revenue will not occur in a future period. The Company has historically not experienced any incidents that had a material impact on its consolidated financial statements. Accordingly, any estimated refunds related to these agreements in the condensed consolidated financial statements are not material during the periods presented. Usage-based consideration is primarily related to fees charged for the Company’s customer’s use of excess bandwidth when accessing the Company’s platform in a given period and is recognized as revenue in the period in which the usage occurs.
