Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies Other than policies noted below, there have been no significant changes to the significant accounting policies disclosed in Note 2 of the audited consolidated financial statements as of January 31, 2021 and 2020 and for the years ended January 31, 2021, 2020, and 2019. Common Stock Warrants Liabilities The Company assumed 10,470,562 publicly-traded warrants (“Public Warrants”) and 6,521,568 private placement warrants issued to NGP Switchback, LLC (“Private Placement Warrants” and, together with the Public Warrants, the “Common Stock Warrants”) upon the Merger, all of which were issued in connection with Switchback’s initial public offering and subsequent overallotment (other than 1,000,000 Private Placement Warrants that were issued in connection with the closing of the Merger) and entitle the holder to purchase one share of the Company’s Common stock, par value $0.0001 (“Common Stock”) at an exercise price of $11.50 per share. During the three months ended April 30, 2021, 6,413,057 Public Warrants and 4,347,712 Private Placement Warrants were exercised. The Public Warrants are publicly traded and are exercisable for cash unless certain conditions occur, such as the failure to have an effective registration statement related to the shares issuable upon exercise or redemption by the Company under certain conditions, at which time the warrants may be cashless exercised. The Private Placement Warrants are non-redeemable The Company evaluated the Common Stock Warrants and concluded that they do not meet the criteria to be classified within stockholders’ equity. The agreement governing the Common Stock Warrants includes a provision (“Replacement of Securities Upon Reorganization”), the application of which could result in a different settlement value for the Common Stock Warrants depending on their holder. Because the holder of an instrument is not an input into the pricing of a fixed-for-fixed Contingent Earnout Liability In connection with the Reverse Recapitalization and pursuant to the Merger Agreement and Plan of Merger dated as of September 23, 2020 by and among the Company, Lightning Merger Sub Inc., and Switchback (“Merger Agreement”), eligible ChargePoint equity holders are entitled to receive additional shares of the Company’s Common Stock upon the Company achieving certain Earnout Triggering Events (as described in the Merger Agreement and Note 9). In accordance with ASC 815-40, The estimated fair value of the contingent consideration was determined using a Monte Carlo simulation using a distribution of potential outcomes on a monthly basis over the Earnout Period (as defined in Note 9) prioritizing the most reliable information available. The assumptions utilized in the calculation are based on the achievement of certain stock price milestones, including the current Company Common Stock price, expected volatility, risk-free rate, expected term and dividend rate. The contingent earnout liability is categorized as a Level 3 fair value measurement (see Fair Value of Financial Instruments accounting policy as described above) because the Company estimates projections during the Earnout Period utilizing unobservable inputs. Contingent earnout payments involve certain assumptions requiring significant judgment and actual results may differ from assumed and estimated amounts. Use of Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results and outcomes could differ significantly from the Company’s estimates, judgments, and assumptions. Significant estimates include determining standalone selling price for performance obligations in contracts with customers, the estimated expected benefit period for deferred contract acquisition costs, allowances for doubtful accounts, inventory reserves, the useful lives of long-lived assets, the determination of the incremental borrowing rate used for operating lease liabilities, the valuation of redeemable convertible preferred stock warrants and common stock warrants, including Common Stock Warrants as a result of the Merger, contingent earnout liability, the value of common stock and other assumptions used to measure stock-based compensation, and the valuation of deferred income tax assets and uncertain tax positions. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions. Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents and accounts receivable. Cash and cash equivalents are held in domestic and foreign cash accounts with large, creditworthy financial institutions. The Company has not experienced any losses on its deposits of cash and cash equivalents through deposits with federally insured commercial banks and at times cash balances may be in excess of federal insurance limits. The Company has not experienced any losses on its deposits of cash and cash equivalents. Accounts receivable are stated at the amount the Company expects to collect. The Company generally does not require collateral or other security in support of accounts receivable. To reduce credit risk, management performs ongoing credit evaluations of its customers’ financial condition. Concentration of credit risk with respect to trade accounts receivable is considered to be limited due to the diversity of the Company’s customer base and geographic sales areas. As of April 30, 2021 and January 31, 2021, one customer individually accounted for 11% and 16% of accounts receivable, net, respectively. For the three months ended April 30, 2021 and 2020, there were no customers that represented 10% or more of total revenue. The Company’s revenue is concentrated in the infrastructure needed for charging EVs, an industry which is highly competitive and rapidly changing. Significant technological changes within the industry or customer requirements, or the emergence of competitive products with new capabilities or technologies, could adversely affect the Company’s operating results. Impact of COVID-19 In March 2020, the World Health Organization characterized COVID-19 COVID-19, COVID-19 As a result of the COVID-19 non-essential While the ultimate duration and extent of the COVID-19 COVID-19 Segment Reporting The Company operates as one operating segment because its chief operating decision maker, who is its Chief Executive Officer, reviews its financial information on a consolidated basis for purposes of making decisions regarding allocating resources and assessing performance. Fair Value of Financial Instruments Fair value is defined as an exchange price that would be received to sell 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. Assets and liabilities measured at fair value are classified into the following categories based on the inputs used to measure fair value: • (Level 1) — Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date; • (Level 2) — Inputs other than quoted prices in active markets that are observable for the asset or liability, either directly or indirectly; and • (Level 3) — Inputs that are unobservable for the asset or liability. The Company classifies financial instruments in Level 3 of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of inputs that are readily observable, either directly or indirectly. The Company’s assessment of a particular input to the fair value measurement requires management to make judgments and consider factors specific to the asset or liability. The fair value hierarchy requires the use of observable market data when available in determining fair value. The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each period. There were no transfers between levels during the periods presented. The Company had no material non-financial assets non-recurring basis The carrying values of the Company’s cash equivalents, accounts receivable, net, accounts payable, and accrued and other current liabilities approximate fair value based on the highly liquid, short-term nature of these instruments. Remaining Performance Obligations Remaining performance obligations represents the amount of contracted future revenue not yet recognized as the amounts relate to undelivered performance obligations, including both deferred revenue and non-cancellable contracted Deferred Revenue Deferred revenue represents billings or payments received in advance of revenue recognition and is recognized in revenue upon transfer of control. Balances consist primarily of software subscription services and extended Assure maintenance services not yet provided as of the balance sheet date. Contract assets, which represent services provided or products transferred to customers in advance of the date the Company has a right to invoice, are netted against deferred revenue on a customer-by-customer basis. non-current Accounting Pronouncements The Company is provided the option to adopt new or revised accounting guidance as an “emerging growth company” under the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”) either (1) within the same periods as those otherwise applicable to public business entities, or (2) within the same time periods as non-public business non-public business Recently Issued Accounting Standards Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, No. 2019-04. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, step-up in In August 2020, the FASB issued ASU 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) 815-40), In October 2020, the FASB issued ASU 2020-08, Codification Improvements to Subtopic 310-20 | 2. Summary of Significant Accounting Policies Use of Estimates The preparation of the accompanying consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions about future events. These estimates and the underlying assumptions affect the amounts of assets and liabilities reported, disclosures about contingent assets and liabilities, and reported amounts of revenue and expenses. Actual results and outcomes could differ significantly from the Company’s estimates, judgments, and assumptions. Significant estimates include determining standalone selling price for performance obligations in contracts with customers, the estimated expected benefit period for deferred contract acquisition costs, allowances for doubtful accounts, inventory reserves, the useful lives of long-lived assets, the determination of the incremental borrowing rate used for operating lease liabilities, the valuation of redeemable convertible preferred stock warrants and common stock warrants, the value of common stock and other assumptions used to measure stock-based compensation, and the valuation of deferred income tax assets and uncertain tax positions. These estimates and assumptions are based on management’s best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, including the current economic environment, which management believes to be reasonable under the circumstances. The Company adjusts such estimates and assumptions when facts and circumstances dictate. Changes in those estimates resulting from continuing changes in the economic environment will be reflected in the financial statements in future periods. As future events and their effects cannot be determined with precision, actual results could materially differ from those estimates and assumptions. Concentration of Credit Risk and Other Risks and Uncertainties Financial instruments that potentially subject the Company to credit risk consist primarily of cash and cash equivalents, short-term investments, and accounts receivable. Cash and cash equivalents are held in domestic and foreign cash accounts with large, creditworthy financial institutions. The Company has not experienced any losses on its deposits of cash and cash equivalents through deposits with federally insured commercial banks and at times cash balances may be in excess of federal insurance limits. Short-term investments consist of U.S. treasury bills that carry high-credit ratings and accordingly, minimal credit risk exists with respect to these balances. Accounts receivable are stated at the amount the Company expects to collect. The Company generally does not require collateral or other security in support of accounts receivable. To reduce credit risk, management performs ongoing credit evaluations of its customers’ financial condition. Concentration of credit risk with respect to trade accounts receivable is considered to be limited due to the diversity of the Company’s customer base and geographic sales areas. As of January 31, 2021, one customer individually accounted for 16% of accounts receivable, net. As of January 31, 2020, there were no customers that accounted for 10% or more of accounts receivable, net. For the years ended January 31, 2021, 2020, and 2019 there were no customers that represented 10% or more of total revenue. The Company’s revenue is concentrated in the infrastructure needed for charging EVs, an industry which is highly competitive and rapidly changing. Significant technological changes within the industry or customer requirements, or the emergence of competitive products with new capabilities or technologies, could adversely affect the Company’s operating results. In December 2019, COVID-19 COVID-19 COVID-19 While the duration and extent of the COVID-19 COVID-19 COVID-19 COVID-19 COVID-19 While the Company has developed and continues to develop plans to help mitigate the potential negative impact of COVID-19, Segment Reporting Operating segments are defined as components of an entity where discrete financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company operates as one operating segment because its CODM, who is its Chief Executive Officer, reviews its financial information on a consolidated basis for purposes of making decisions regarding allocating resources and assessing performance. The Company has no segment managers who are held accountable by the CODM for operations, operating results, and planning for levels of components below the consolidated unit level. Cash, Cash Equivalents, and Restricted Cash The Company considers all highly liquid investments with an original maturity of three months or less, when purchased, to be cash equivalents. Cash equivalents may be invested in money market funds. Cash and cash equivalents are carried at cost, which approximates their fair value. Restricted cash of $0.4 million as of January 31, 2021 and 2020 and $0.5 million as of January 31, 2019 relates to cash deposits restricted under letters of credit issued in support of customer agreements. The reconciliation of cash, cash equivalents, and restricted cash to amounts presented in the consolidated statements of cash flows were as follows: January 31, 2021 2020 2019 (in thousands) Cash and cash equivalents $ 145,491 $ 72,753 $ 205,238 Restricted cash 400 400 460 Total cash, cash equivalents, and restricted cash $ 145,891 $ 73,153 $ 205,698 Short-term Investments The Company considers investments with original maturities greater than three months and remaining maturities less than one year to be short-term investments. The Company’s short-term investments consist of U.S. treasury bills and are classified as available for sale and reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income (loss). For short-term investments sold prior to maturity, the cost of investments sold is based on the specific identification method. Realized gains and losses on the sale of short-term investments are recorded in other income (expense), net in the consolidated statements of operations. Other-than-temporary Impairment The Company evaluates its short-term investments with unrealized losses for other-than-temporary impairment. When assessing short-term investments for other-than-temporary declines in value, the Company considers factors such as, among other things, the extent and length of time the investment’s fair value has been lower than its cost basis, the financial condition and near-term prospects of the investee, the Company’s ability and intent to retain the investment for a period of time sufficient to allow for any anticipated recovery in fair value, and the expected cash flows from the security. If any adjustment to fair value reflects a decline in the value of the investment that the Company considers to be “other than temporary,” the Company reduces the investment to fair value through a charge to the consolidated statements of operations and consolidated statements of comprehensive loss. No such adjustments were necessary during the periods presented. Accounts Receivable, net Accounts receivable are recorded at the invoiced amount and are non-interest one-time Beginning Additions Write-offs Ending (in thousands) Year ended January 31, 2021 Allowance for doubtful accounts $ 2,000 $ 121 $ (121 ) $ 2,000 Year ended January 31, 2020 Allowance for doubtful accounts $ 3,124 $ 339 $ (1,463 ) $ 2,000 Year ended January 31, 2019 Allowance for doubtful accounts $ 1,316 $ 1,812 $ (4 ) $ 3,124 Inventories Inventories are stated at the lower of cost or net realizable value. Cost is computed using standard cost, which approximates actual cost, on a first-in, first-out Property and Equipment, net Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the respective assets, as follows: Useful Lives Furniture and fixtures 3 to 5 years Computers and software 3 to 5 years Machinery and equipment 3 to 5 years Tooling 3 to 5 years Leasehold improvements Shorter of the estimated Owned and operated systems 5 to 7 years Leasehold improvements are amortized over the shorter of estimated useful lives of the assets or the lease term. Expenditures for repairs and maintenance are charged to expense as incurred. Upon disposition, the cost and related accumulated depreciation are removed from the accounts and the resulting gain or loss is reflected in the consolidated statements of operations. ChargePoint-as-a-Service Internal-Use The Company capitalizes qualifying internal-use internal-use internal-use Leases On February 1, 2019, the Company early adopted the requirements of Accounting Standards Update (“ASU”) 2016-02, Lessee The Company determines if a contract is a lease or contains a lease at the inception of the contract and reassesses that conclusion if the contract is modified. All leases are assessed for classification as an operating lease or a finance lease. Operating lease right-of-use The Company’s lease liabilities are recognized at the applicable lease commencement date based on the present value of the lease payments required to be paid over the lease term. As the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate to discount the lease payments to present value. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The Company’s ROU assets are also recognized at the applicable lease commencement date. The ROU asset equals the carrying amount of the related lease liability, adjusted for any lease payments made prior to lease commencement and lease incentives provided by the lessor. Variable lease payments are expensed as incurred and do not factor into the measurement of the applicable ROU asset or lease liability. The term of the Company’s leases equals the non-cancellable The Company’s lease contracts often include lease and non-lease non-lease The Company elected the package of practical expedients permitted under the transition guidance, which allows the Company to carry forward 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. The Company has elected, for all classes of underlying assets, not to recognize ROU assets and lease liabilities for leases with a term of twelve months or less. Lease cost for short-term leases is recognized on a straight-line basis over the lease term. Lessor The Company leases networked charging systems to customers within certain CPaaS contracts. The leasing arrangements the Company enters into with lessees are operating leases, and as a result, the underlying asset is carried at its carrying value as owned and operated systems within property and equipment, net on the consolidated balance sheets. Adoption of ASC 842 did not have a material impact on the Company’s accounting as a lessor. Impairment of Long-Lived Assets The Company evaluates long-lived assets or asset groups for impairment whenever events indicate that the carrying amount of an asset or asset group may not be recoverable based on expected future cash flows attributable to that asset or asset group. Recoverability of assets held and used is measured by comparison of the carrying amounts of an asset or an asset group to the estimated future undiscounted cash flows which the asset or asset group is expected to generate. If the carrying amount of an asset or asset group exceeds estimated undiscounted future cash flows, then an impairment charge would be recognized based on the excess of the carrying amount of the asset or asset group over its fair value. Assets to be disposed of are reported at the lower of their carrying amount or fair value less costs to sell. There were no impairments of long-lived assets for the years ended January 31, 2021, 2020, and 2019. Business Combinations The total purchase consideration for an acquisition is measured as the fair value of the assets transferred, equity instruments issued, and liabilities assumed at the acquisition date. Costs that are directly attributable to the acquisition are expensed as incurred and included in general and administrative expense in the Company’s consolidated statements of operations. Identifiable assets (including intangible assets), liabilities assumed (including contingent liabilities), and noncontrolling interests in an acquisition are measured initially at their fair values at the acquisition date. The Company recognizes goodwill if the fair value of the total purchase consideration and any noncontrolling interests is in excess of the net fair value of the identifiable assets acquired and the liabilities assumed. Determining the fair value of assets acquired and liabilities assumed requires management to use significant judgment and estimates including the selection of valuation methodologies, cost of capital, future cash flows, and discount rates. The Company’s estimates of fair value are based on 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, 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. The Company includes the results of operations of the acquired business in the consolidated financial statements beginning on the acquisition date. Goodwill Goodwill represents the excess of the purchase price of an acquired business over the fair value of the net tangible and identifiable intangible assets acquired. The carrying amount of goodwill is reviewed for impairment at least annually, in the second quarter, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. As of January 31, 2021 and 2020, the Company had a single operating segment and reporting unit structure. As part of the annual goodwill impairment test performed in the second quarter, the Company first performs a qualitative assessment to determine whether further impairment testing is necessary. If, as a result of the qualitative assessment, it is more likely than not that the fair value of the reporting unit is less than its carrying amount, the quantitative impairment test will be required. If the Company has determined it necessary to perform a quantitative impairment assessment, the Company will compare the fair value of the reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value, limited to the total amount of goodwill of the reporting unit. The carrying value of goodwill was $1.2 million as of January 31, 2021 and 2020, and no goodwill impairment has been recognized to date. Fair Value of Financial Instruments Fair value is defined as an exchange price that would be received to sell 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. Assets and liabilities measured at fair value are classified into the following categories based on the inputs used to measure fair value: • (Level 1) — Quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date; • (Level 2) — Inputs other than quoted prices in active markets that are observable for the asset or liability, either directly or indirectly; and • (Level 3) — Inputs that are unobservable for the asset or liability. The Company classifies financial instruments in Level 3 of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of inputs that are readily observable, either directly or indirectly. The Company’s assessment of a particular input to the fair value measurement requires management to make judgments and consider factors specific to the asset or liability. The fair value hierarchy requires the use of observable market data when available in determining fair value. The Company recognizes transfers between levels within the fair value hierarchy, if any, at the end of each period. There were no transfers between levels during the periods presented. The Company had no material non-financial non-recurring The carrying values of the Company’s cash equivalents, short-term investments, accounts receivable, net, accounts payable, and accrued and other current liabilities approximate fair value based on the highly liquid, short-term nature of these instruments. Redeemable Convertible Preferred Stock Warrants Warrants to purchase shares of the Company’s Series B, D, and E redeemable convertible preferred stock are classified as liabilities as the underlying redeemable convertible preferred stock is considered redeemable and may require the Company to transfer assets upon exercise. Redeemable convertible preferred stock warrants are recorded within noncurrent liabilities on the consolidated balance sheets. The warrants were recorded at fair value upon issuance and are subject to remeasurement to fair value at each balance sheet date. Changes in fair value of the redeemable convertible preferred stock warrant liability are recorded in the consolidated statements of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the exercise or expiration of the warrants, conversion of redeemable convertible preferred stock into common stock, or until the redeemable convertible preferred stock is otherwise no longer redeemable. At that time, the redeemable convertible preferred stock warrant liability will be reclassified to redeemable convertible preferred stock or additional paid-in Common Stock Warrants Warrants to purchase shares of the Company’s common stock are equity classified and recognized within additional paid-in paid-in Revenue Recognition On February 1, 2019, the Company early adopted ASU No. 2014-09. • 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; and • Recognition of revenue when, or as, the Company satisfies a performance obligation. Significant judgment and estimates are necessary for the allocation of the proceeds received from an arrangement to the multiple performance obligations and the appropriate timing of revenue recognition. The Company enters into contracts with customers that regularly include promises to transfer multiple products and services, such as charging systems, software subscriptions, extended maintenance, and professional services. For arrangements with multiple products or services, the Company evaluates whether the individual products or services qualify as distinct performance obligations. In its assessment of whether products or services are a distinct performance obligation, the Company determines whether the customer can benefit from the product or service on its own or with other readily available resources and whether the service is separately identifiable from other products or services in the contract. This evaluation requires the Company to assess the nature of each of its networked charging systems, subscriptions, and other offerings and how each is provided in the context of the contract, including whether they are significantly integrated which may require judgment based on the facts and circumstances of the contract. The transaction price for each contract is determined based on the amount the Company expects to be entitled to receive in exchange for transferring the promised products or services to the customer. Collectability of revenue is reasonably assured based on historical evidence of collectability of fees the Company charges its customers. The transaction price in the contract is allocated to each distinct performance obligation in an amount that represents the relative amount of consideration expected to be received in exchange for satisfying each performance obligation. Revenue is recognized when performance obligations are satisfied. Revenue is recorded based on the transaction price excluding amounts collected on behalf of third-parties such as sales taxes, which are collected on behalf of and remitted to governmental authorities, or driver fees, collected on behalf of customers who offer public charging for a fee. When agreements involve multiple distinct performance obligations, the Company accounts for individual performance obligations separately if they are distinct. The Company applies significant judgment in identifying and accounting for each performance obligation, as a result of evaluating terms and conditions in contracts. The transaction price is allocated to the separate performance obligations on a relative standalone selling price (“SSP”) basis. The Company determines SSP based on observable standalone selling price when it is available, as well as other factors, including the price charged to its customers, its discounting practices, and its overall pricing objectives, while maximizing observable inputs. In situations where pricing is highly variable, or a product is never sold on a stand-alone basis, the Company estimates the SSP using the residual approach. The Company usually bills its customers at the onset of the arrangement for both the products and a predetermined period of time for services. Contracts for services typically range from annual to multi-year agreements with typical payment terms of 30 to 90 days. Networked charging systems revenue Networked charging systems revenue includes revenue related to the deliveries of EV charging system infrastructure. The Company recognizes revenue from sales of networked charging systems upon shipment to the customer, which is when the performance obligation has been satisfied. Subscriptions revenue Subscriptions revenue consists of services related to Cloud, as well as extended maintenance service plans under Assure. Subscriptions revenue also consists of CPaaS revenue, which combines the customer’s use of the Company’s owned and operated systems with Cloud and Assure programs into a single subscription. CPaaS subscriptions contain a lease for the customer’s use of the Company’s owned and operated systems unless the location allows the Company to receive incremental economic benefit from regulatory credits earned on that owned and operated system. Lessor revenue relates to operating leases and historically has not been material. Subscriptions revenue is recognized over time on a straight-line basis as the Company has a stand-ready obligation to deliver such services to the customer. Other revenue Other revenue consists of fees received for transferring regulatory credits earned for participating in low carbon fuel programs in approved states, charging related fees received from drivers using charging sites owned and operated by the Company, net transaction fees earned for processing payments collected on driver charging sessions at charging sites owned by ChargePoint customers, and other professional services. Revenue from regulatory credits is recognized at the point in time the regulatory credits are transferred. Revenue from fees for owned and operated sites is recognized over time on a straight-line basis over the performance period of the service contract as the Company has a stand-ready obligation to deliver such services. Revenue from driver charging sessions and charging transaction fees is recognized at the point in time the charging session or transaction is completed. Revenue from professional services is recognized as the services are rendered. Revenue Recognition (ASC 605) During the fiscal year ended January 31, 2019, the Company recognized revenue under ASC Topic 605, Revenue Recognition (“ASC 605”) when persuasive evidence of an arrangement existed, delivery had occurred, the fee was fixed or determinable, and collectability was probable. Revenue for this period was generally recognized net of allowances for returns and any taxes collected from customers and subsequently remitted to governmental authorities. When a sales arrangement contained multiple elements, the Company first determined whether the delivered items qualify as separate units of accounting. A delivered item qualified as a separate unit of accounting when it had value to the customer on a standalone basis and when an arrangement included a general right of return relative to the delivered item, delivery, or performance of any undelivered items was considered probable or substantially in control of the Company. The Company then allocated revenue to each separate unit of accounting based on the relative selling price method and using the established selling price hierarchy. The selling price for a unit of accounting was based on its vendor specific objective evidence (“VSOE”), if available, third-party evidence (“TPE”) if VSOE was not available, or best estimate of selling price (“ESP”) if neither VSOE nor TPE was available. The Company generally utilized ESP. The objective of ESP was to determine the price at which the Company would transact a sale if the product or service were sold on a standalone basis. ESP was generally used for new or highly customized offerings and solutions or offerings not priced within a narrow range, and it applied to a large proportion of the Company’s arrangements with multiple deliverables. The process for determining ESP requires judgment and considers multiple factors that may vary over time depending upon the unique facts and circumstances related to each deliverable. Lessor Revenue The leasing arrangements the Company enters into with lessees are operating leases. The Company recognizes operating lease revenue on a straight-line basis over the lease term and expenses deferred initial direct costs on the same basis. Operating lease revenue is classified as subscriptions revenue in the Company’s consolidated statements of operations. Operating lease revenue and the future maturities of lease payments from lessees was not material to the consolidated financial statements for all periods presented. Remaining Performance Obligations Remaining performance obligations represents the amount of contracted future revenue not yet recognized as the amounts relate to undelivered performance obligations, including both deferred revenue and non-cancelable Deferred Revenue Deferred revenue represents billings or payments received in advance of revenue recognition and is recognized in revenue upon transfer of control. Balances consist primarily of software subscription services and extended Assure maintenance services not yet provided as of the balance sheet date. Contract assets, which represent services provided or products transferred to customers in advance of the date the Company has a right to invoice, are netted against deferred revenue on a customer-by-customer Cost of Revenue Cost of networked charging systems revenue includes the material costs for parts and manufacturing costs for the hardware products, compensation, including salaries and related personnel expenses, including stock-based compensation, warranty provisions, depreciation of manufacturing related equipment and facilities, amortization of capitalized internal-use Cost of subscriptions revenue includes network and wireless connectivity costs for subscription services, field maintenance costs for Assure to support the Company’s network of systems, depreciation of owned and operated systems used in CPaaS arrangements, amortization of capitalized internal-use Cost of other revenue includes costs for the Company’s owned and operated charging sites, as well as costs of environmental and professional services. Costs to Obtain a Customer Contract Sales commissions are considered incremental and recoverable costs of acquiring customer contracts. Beginning at the Company’s adoption of ASC 606 on February 1, 2019, incremental and recoverable costs for the sale of cloud enabled software and extended maintenance service plans are capitalized as deferred contract acquisition costs within prepaid expenses and other current assets and other assets on the consolidated balance sheets and amortized on a straight-line basis over the anticipated benefit period of five years. The benefit period was estimated by taking into consideration the length of customer contracts, renewals, technology lifecycle, and other factors.

The fair value of each stock option award is estimated on the grant date using the Black-Scholes option pricing model. The Black-Scholes option pricing model requires the input of highly subjective assumptions, including the fair value of the underlying common stock, the expected term of the option, the expected volatility of the price of the Company’s common stock, risk-free interest rates, and the expected dividend yield of the Company’s common stock. The assumptions used to determine the fair value of the awards represent management’s best estimates. These estimates involve inherent uncertainties and the application of management’s judgment. The Company amortizes the fair value of each stock award on a straight-line basis over the requisite service period of the awards. Stock-based compensation expense is based on the value of the portion of stock-based awards that is ultimately expected to vest. As such, the Company’s stock-based compensation is reduced for the estimated forfeitures at the date of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.
