Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2. Summary of Significant Accounting Policies Use of Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make, on an ongoing basis, estimates and assumptions that affect the amounts reported and disclosed in the financial statements and the accompanying notes. Actual results could differ from these estimates. Such estimates include, but are not limited to, the fair value of acquired intangible assets and goodwill, useful lives of acquired intangible assets and property and equipment, timing and costs associated with our asset retirement obligations, the standalone selling price allocation included in contracts with multiple performance obligations, the expected benefit period for deferred commissions, the useful life of capitalized internal-use software costs, the incremental borrowing rate we use to determine our lease liabilities, the valuation of deferred income tax assets, and unrecognized tax benefits, among others. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Revenue Recognition We derive our revenue primarily from three sources: (1) subscription revenue, which is comprised of subscription fees from customers who have access to our content cloud platform which includes routine customer support; (2) revenue from customers purchasing our premier services package; and (3) revenue from professional services such as implementing best practice use cases, project management and implementation consulting services. Revenue is recognized when control of these services is transferred to a customer. The amount of revenue recognized reflects the consideration we expect to be entitled to in exchange for those services. We determine revenue recognition through the following steps: • Identification of the contract, or contracts, with a customer • Identification of the performance obligations in the contract • Determination of the transaction price • Allocation of the transaction price to the performance obligations in the contract • Recognition of revenue as we satisfy a performance obligation Subscription and Premier Services Revenues We recognize revenue as we satisfy our performance obligation. Accordingly, due to our subscription model, we recognize revenue for our subscription and premier services ratably over the contract term. We typically invoice our customers at the beginning of the term, in multi-year, annual, quarterly or monthly installments. Our subscription and premier services contracts generally range from one to three years in length, are typically non-cancellable and do not contain refund-type provisions. Revenue is presented net of sales and other taxes we collect on behalf of governmental authorities. Professional Services Professional services are generally billed on a fixed price basis, for which revenue is recognized over time based on the proportion performed. Contracts with Multiple Performance Obligations Our contracts can include multiple performance obligations which may consist of some or all of subscription services, premier services, and professional services. For these contracts, we account for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative standalone selling price basis. We determine the standalone selling prices based on our overall pricing objectives, taking into consideration discounting practices, the size and volume of our transactions, the customer demographic, the geographic area where services are sold, price lists, our go-to-market strategy, historical standalone sales and contract prices. Deferred Revenue Deferred revenue consists of billings in advance of revenue recognition generated by our subscription services, premier services, and professional services described above. Cost of Revenue Cost of revenue consists primarily of costs related to providing our subscription services to our paying customers, including employee compensation and related expenses for data center operations, customer support and professional services personnel, payments to outside technology service providers, depreciation of servers and equipment, security services and other tools, as well as amortization expense associated with capitalized internally developed software and acquired technology. We allocate overhead such as rent, information technology costs and employee benefit costs to all departments based on headcount. Deferred Commissions Sales commissions earned by our sales force are considered incremental and recoverable costs of obtaining a contract with a customer. Sales commissions for new contracts are deferred and then amortized on a straight-line basis over a period of benefit that we have estimated to be five years. We determined the period of benefit by taking into consideration the duration of our customer contracts, the life cycles of our technology and other factors. Sales commissions for renewal contracts are deferred and then amortized on a straight-line basis over the related contractual renewal period. Amortization expense is included in sales and marketing expenses on the consolidated statements of operations. We deferred sales commissions costs of $59.2 million, $48.0 million and $44.0 million during the years ended January 31, 2022, 2021 and 2020, respectively, and amortized $45.9 million, $36.1 million and $25.9 million of deferred commissions during the same periods respectively. Certain Risks and Concentrations Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. Although we deposit our cash with multiple financial institutions, our deposits, at times, may exceed deposit insurance coverage limits. We sell to a broad range of customers. Our revenue is derived primarily from the United States across a multitude of industries. Accounts receivable are derived from the delivery of our services to customers primarily located in the United States. We accept and settle our accounts receivable using credit cards, electronic payments and checks. A majority of our lower dollar value invoices are settled by credit card on or near the date of the invoice. We do not require collateral from customers to secure accounts receivable. We maintain an allowance for doubtful accounts based upon the expected collectability, which takes into consideration specific customer creditworthiness and current economic trends. We believe collections of our accounts receivable are probable based on the size, industry diversification, financial condition and past transaction history of our customers. As of January 31, 2022 and 2021, one reseller, which is also a customer, accounted for more than 10% of total accounts receivable. No single customer represented over 10% of revenue in the years ended January 31, 2022 and 2021. One reseller, which is also a customer, represented 10% of revenue for the year ended January 31, 2020. We serve our customers and users from data center facilities operated by third parties. In order to reduce the risk of down time of our subscription services, we have established data centers and third-party cloud computing and hosting providers in various locations in the United States and abroad. We have internal procedures to restore services in the event of disaster at any one of our current data center facilities. Even with these procedures for disaster recovery in place, our cloud services could be significantly interrupted during the implementation of the procedures to restore services. Geographic Locations For the years ended January 31, 2022, 2021 and 2020, revenue attributable to customers in the United States was 68%, 72% and 75%, respectively. For the years ended January 31, 2022, 2021 and 2020 revenue attributable to customers in Japan was 18%, 14%, and 10%, respectively. As of January 31, 2022 and 2021, property and equipment located in the United States was approximately 95% and 96%, respectively. Foreign Currency Translation and Transactions The functional currency of our principal foreign subsidiary is the U.S. dollar; for the other foreign subsidiaries, the functional currency is generally the local currency. Adjustments resulting from translating foreign functional currency financial statements into U.S. dollars for those entities that do not have U.S. dollars as their functional currency are recorded as part of a separate component of the consolidated statements of comprehensive loss. Foreign currency transaction gains and losses are included in the consolidated statements of operations for the period. Monetary assets and liabilities denominated in a foreign currency are translated into U.S. dollars at the exchange rate on the balance sheet date. Revenue and expenses are translated at the average exchange rate during the period. Equity transactions are translated using historical exchange rates. Translation adjustments were $4.5 million and not material as of January 31, 2022 and 2021, respectively. We incurred $3.7 million in foreign currency transaction losses during the year ended January 31, 2022, $2.5 million in foreign currency transaction gains during the year ended January 31, 2021 and $1.1 million in foreign currency transaction losses during the year ended January 31, 2020. Cash and Cash Equivalents We consider all highly liquid investments with an initial maturity of 90 days or less at the date of purchase to be cash equivalents. We maintain such funds in overnight cash deposits, money market funds, and certificates of deposit. Fair Value of Financial Instruments We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. We define fair value as the exchange price that would be received from selling an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Three levels of inputs may be used to measure fair value: • Level 1—Observable inputs are unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2—Observable inputs are quoted prices for similar assets and liabilities in active markets or inputs other than quoted prices which are observable for the assets or liabilities, either directly or indirectly through market corroboration, for substantially the full term of the financial instruments. • Level 3—Unobservable inputs that are supported by little or no market activity and are significant to the fair value of the assets or liabilities. These inputs are based on our own assumptions used to measure assets and liabilities at fair value and require significant management judgment or estimation. Derivative Instruments and Hedging We measure derivative financial instruments at fair value and recognize them as either assets or liabilities on our consolidated balance sheets. We record changes in the fair value of derivative financial instruments designated as cash flow hedges in other comprehensive income (loss). When the hedged transaction affects earnings, we subsequently reclassify the net derivative gain or loss within other comprehensive income (loss) into the same line as the hedged item on the consolidated statements of operations to offset the changes in the hedged transaction. The cash flow effects related to derivative financial instruments designated as cash flow hedges are included within operating activities on our consolidated statements of cash flows. Accounts Receivable and Related Allowance Accounts receivable are recorded at the invoiced amounts and do not bear interest. We maintain an allowance for estimated losses inherent in our accounts receivable portfolio. We assess the collectability of the accounts by taking into consideration the aging of our trade receivables, historical experience, and management judgment. We write off trade receivables against the allowance when management determines a balance is uncollectible and no longer intends to actively pursue collection of the receivable. We record a contract asset when revenue is recognized in advance of invoicing. Contract assets are presented within accounts receivable on the consolidated balance sheets. Property and Equipment Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets, generally three to five years. Leasehold improvements are amortized over the shorter of their estimated useful lives or the remaining lease term. Depreciation commences once the asset is placed in service. Construction in progress is primarily related to the construction or development of property and equipment which have not yet been placed in service for their intended use. Leases We determine whether an arrangement contains a lease at inception. A contract is or contains a lease if the contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. To determine whether a contract is or contains a lease, we consider all relevant facts and circumstances to assess whether the customer has both of the following: • The right to obtain substantially all of the economic benefits from use of the identified asset • The right to direct the use of the identified asset We recognize lease liabilities and right-of-use assets at lease commencement. We measure lease liabilities based on the present value of lease payments over the lease term discounted using the rate implicit in the lease when that rate is readily determinable or our incremental borrowing rate. We estimate our incremental borrowing rate based on an analysis of publicly traded debt securities of companies with credit and financial profiles similar to our own and adjust our incremental borrowing rate to reflect the corresponding lease term. We do not include in the lease term options to extend or terminate the lease unless it is reasonably certain that we will exercise any such options. We account for the lease and non-lease components as a single lease component for all our leases. We measure right-of-use assets based on the corresponding lease liabilities adjusted for (i) prepayments made to the lessor at or before the commencement date, (ii) initial direct costs we incur, and (iii) tenant incentives under the lease. We evaluate the recoverability of our right-of-use assets for possible impairment in accordance with our long-lived assets policy. We do not recognize right-of-use assets or lease liabilities for short-term leases, which have a lease term of twelve months or less, and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term. Operating leases are reflected in operating lease right-of-use assets, operating lease liabilities, and operating lease liabilities, non-current on our consolidated balance sheets. Finance leases are included in property and equipment, net, finance lease liabilities, and finance lease liabilities, non-current on our consolidated balance sheets. We begin recognizing rent expense when the lessor makes the underlying asset available to us. We recognize rent expense under our operating leases on a straight-line basis. For finance leases, we record interest expense on the lease liability in addition to amortizing the right-of-use asset (generally straight-line) over the shorter of the lease term or the useful life of the right-of-use asset. Variable lease payments are expensed as incurred and are not included within the lease liabilities and right-of-use assets calculation. We generally recognize sublease income on a straight-line basis over the sublease term. Business Combinations We allocate the fair value of purchase consideration to the tangible assets acquired, liabilities assumed and intangible assets acquired based on their estimated fair values. The excess of the fair value of purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. Such valuations require management to make significant estimates and assumptions, especially with respect to intangible assets. Significant estimates in valuing certain intangible assets include, but are not limited to, future expected cash flows from acquired users, acquired technology, and trade names from a market participant perspective, useful lives and discount rates. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but which are inherently uncertain and unpredictable and, as a result, actual results may differ from estimates. During the measurement period, which is one year from the acquisition date, we may record adjustments to the assets acquired and liabilities assumed, with the corresponding offset to goodwill. Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. Impairment Assessment of Long-Lived Assets, Including Goodwill and Other Acquired Intangible Assets We evaluate the recoverability of property and equipment for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of property and equipment is not recoverable, the carrying amount of such assets is reduced to fair value. We have not recorded any significant impairment charges during the years presented. We review goodwill for impairment at least annually or more frequently if events or changes in circumstances indicate that the carrying value of goodwill may not be recoverable. We have elected to first assess the qualitative factors to determine whether it is more likely than not that the fair value of our single reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the quantitative goodwill impairment test. If we determine that it is more likely than not that its fair value is less than its carrying amount, then the quantitative goodwill impairment test will be performed. The quantitative goodwill impairment test identifies goodwill impairment and measures the amount of goodwill impairment loss to be recognized by comparing the fair value of our single reporting unit with its carrying amount. If the fair value exceeds its carrying amount, no further analysis is required; otherwise, any excess of the goodwill carrying amount over the implied fair value is recognized as an impairment loss, and the carrying value of goodwill is written down to fair value. No impairment of goodwill has been identified during the years presented. Acquired finite-lived intangible assets are typically amortized over the estimated useful lives of the assets, which is generally two to seven years. We evaluate the recoverability of our intangible assets for possible impairment whenever events or circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the future undiscounted cash flows the assets are expected to generate. If such review indicates that the carrying amount of intangible assets is not recoverable, the carrying amount of such assets is reduced to fair value. We have not recorded any such impairment charges during the years presented. Legal Contingencies From time to time, we are subject to litigation and claims that arise in the ordinary course of business. We investigate litigation and claims as they arise and accrue estimates for resolution of legal and other contingencies when losses are probable and estimable. Because the results of litigation and claims cannot be predicted with certainty, we base our loss accruals on the best information available at the time. As additional information becomes available, we reassess our potential liability and may revise our estimates. Such revisions could have a material impact on future quarterly or annual results of operations. Research and Development Costs Research and development costs include personnel costs, including stock-based compensation expense, associated with our engineering personnel and consultants responsible for the design, development and testing of the product, depreciation of equipment used in research and development and allocated overhead for facilities, information technology, and employee benefit costs. Internal-Use Software Costs We capitalize costs to develop software for internal use incurred during the application development stage. Costs related to preliminary project activities and post implementation activities are expensed as incurred. Once an application has reached the development stage, qualifying internal and external costs are capitalized until the application is substantially complete and ready for its intended use. Capitalized qualifying costs are amortized on a straight-line basis when the software is ready for its intended use over an estimated useful life, which is generally three years. Internal-use software costs also include third-party on-premises software, which is amortized over the lesser of five years or the license term. We evaluate the useful lives of these assets on an annual basis and test for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. We capitalize qualifying implementation costs incurred in a hosting arrangement that is a service contract based on the existing guidance for internally developed software, which is presented as part of our prepaid expenses and other current assets and other long-term assets based on the term of the associated hosting arrangement. Qualifying external and internal costs incurred during the application development stage of implementation are capitalized and costs incurred during the preliminary project and post implementation stages are expensed as incurred. We amortize capitalized qualifying implementation costs on a straight-line basis when the module or component of the hosting arrangement is ready for its intended use over the shorter of (i) the contract term plus the renewal period and (ii) three years. The amortization of capitalized qualifying implementation costs is presented in the same line item as fees for the associated hosting arrangement in the consolidated statements of operations. We test for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. Advertising Costs Advertising costs are expensed as incurred and are included in sales and marketing expense. Advertising costs for the years ended January 31, 2022, 2021 and 2020 were $16.6 million, $15.0 million and $25.6 million, respectively. Stock-Based Compensation We determine the fair value of stock options and purchase rights issued to employees under our 2015 Equity Incentive Plan and 2015 Employee Stock Purchase Plan on the date of grant using the Black-Scholes option pricing model, which is impacted by the fair value of our common stock as well as changes in assumptions regarding a number of variables, which include, but are not limited to, the expected common stock price volatility over the term of the awards, the expected term of the awards, risk-free interest rates and the expected dividend yield. We use the market closing price of our Class A common stock as reported on the New York Stock Exchange for the fair value of restricted stock units granted after our IPO. We recognize compensation expense for stock options and restricted stock units, net of estimated forfeitures, on a straight-line basis over the period during which an employee is required to provide services in exchange for the award (generally the vesting period of the award). We estimate future forfeitures at the date of grant and revise the estimates, if necessary, in subsequent periods if actual forfeitures differ from those estimates. We recognize compensation expense of purchase rights granted under our 2015 ESPP on a straight-line basis over the offering period. For performance-based restricted stock units that vest based upon continued service and achievement of certain performance conditions established by the board of directors for a predetermined period, the fair value is determined based upon the market closing price of our Class A common stock on the date of the grant; compensation expense is recognized over the requisite service period if it is probable that the performance condition will be satisfied based on the accelerated attribution method. In addition, we have issued performance-based stock options that vest based upon continued service through the vesting term and achievement of certain market conditions established by the Compensation Committee of our board of directors for a predetermined period. We measure stock-based compensation expense for performance-based stock options containing market conditions based on the estimated grant date fair value determined using the Monte Carlo valuation model; we recognize compensation expense for such awards over the requisite service period using the accelerated attribution method. Income Taxes We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the temporary differences between the financial statement and tax basis of assets and liabilities using the enacted tax rates in effect for the years in which the differences are expected to reverse. The effect on deferred taxes of a change in income tax rates is recognized in the consolidated statements of operations in the period that includes the enactment date. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts we believe are more likely than not to be realized. We recognize tax benefits from uncertain tax positions only if we believe that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. Recently Adopted Accounting Pronouncements In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and by improving consistent application of other areas of Topic 740. We adopted the new standard, effective February 1, 2021, and the adoption did not have a material impact on our consolidated financial statements. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. Reference rate reform refers to the global transition away from certain reference rates, such as LIBOR, and to the introduction of new reference rates that are based on a larger and more liquid population of observable transactions. ASU 2020-04 provides temporary optional expedients and exceptions for applying GAAP to contracts and hedging relationships that reference LIBOR or another reference rate expected to be discontinued as a result of reference rate reform. The amendments in this ASU were effective upon issuance and did not have a material impact on our consolidated financial statements. In August 2020, the FASB issued ASU 2020-06 (ASU 2020-06), Debt – Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity’s Own Equity (Subtopic 815-40). The amendments in this update were implemented by the FASB to reduce the number of accounting models for convertible debt instruments. Under ASU 2020-06, the embedded conversion features are no longer separated from the host contract for convertible instruments with conversion features that are not required to be accounted for as derivatives under Topic 815, or that do not result in substantial premiums accounted for as paid-in capital. Consequently, a convertible debt instrument is accounted for as a single liability measured at its amortized cost, as long as no other features require bifurcation and recognition as derivatives. There is no longer a debt discount representing the difference between the carrying value, excluding issuance costs, and the principal of the convertible debt instrument and, as a result, there is no longer interest expense from the amortization of the debt discount over the term of the convertible debt instrument. The amendments in this update also require the if-converted method to be applied for all convertible instruments when calculating diluted earnings per share. We early adopted the new standard, effective February 1, 2021, using the modified retrospective method. The comparative periods presented and disclosed in the year of adoption are based on legacy guidance. Adoption Impact of ASU 2020-06 on the Opening Balance Sheet as of February 1, 2021 In connection with the adoption of ASU 2020-06, we recognized a $0.6 million decrease of accumulated deficit, a $68.6 million decrease of additional paid-in capital, and a $68.0 million increase of debt, net, noncurrent. The adoption of ASU 2020-06 did not have a material effect on our consolidated statements of operations and cash flows. In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in this update require that an acquirer recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606 instead of fair value on the acquisition date in accordance with Topic 805. We early adopted the new standard, effective November 1, 2021, and the adoption did not have a material impact on our consolidated financial statements.
