Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) and applicable rules and regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. GAAP have been condensed or omitted, and accordingly the balance sheet as of January 31, 2019, and related disclosures, have been derived from the audited consolidated financial statements at that date but do not include all of the information required by U.S. GAAP for complete consolidated financial statements. These unaudited condensed consolidated financial statements have been prepared on the same basis as the Company’s annual consolidated financial statements and, in the opinion of management, reflect all adjustments (consisting only of normal recurring adjustments) that are necessary for the fair statement of the Company’s condensed consolidated financial information. The results of operations for the three and nine months ended October 31, 2019 are not necessarily indicative of the results to be expected for the year ending January 31, 2020 or for any other interim period or for any other future year.

Certain information and footnote 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, the accompanying interim unaudited condensed consolidated financial statements and related financial information should be read in conjunction with the audited consolidated financial statements and the related notes thereto as of and for the year ended January 31, 2019 included in the Company’s prospectus dated June 11, 2019 filed with the SEC pursuant to Rule 424(b) under the Securities Act of 1933, as amended.

Principles of Consolidation

The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

JOBS Act Accounting Election

The Company is an “emerging growth company” (“EGC”) as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). An EGC may take advantage of specified reduced reporting requirements that are otherwise applicable generally to public companies, including, but not limited to, delayed adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley Act”), reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

The Company may take advantage of these exemptions until it is no longer an EGC. The Company would cease to be an EGC upon the earliest to occur of: (i) the first fiscal year following the fifth anniversary of its initial public offering; (ii) the first fiscal year after annual gross revenue is $1.07 billion or more; (iii) the date on which the Company has, during the previous three-year period, issued more than $1.0 billion in non-convertible debt securities; or (iv) the date on which the Company qualifies as a “large accelerated filer,” as defined in Rule 12b-2 under the Exchange Act, which would occur at the end of any fiscal year in which the market value of the Company’s common stock held by non-affiliates exceeded $700.0 million as of the end of the second quarter of that fiscal year, and as of the end of such fiscal year the Company has been a reporting company for at least 12 months.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the Company’s condensed consolidated financial statements and accompanying notes. These estimates are based on information available as of the date of the condensed consolidated financial statements. On a regular basis, management evaluates these estimates and assumptions. Actual results may differ from these estimates and such difference could be material to the Company’s condensed consolidated financial statements.

Estimates and assumptions used by management affect revenue recognition, the allowance for doubtful accounts, the carrying value of long-lived assets, the useful lives of long-lived assets, the fair value of financial instruments, the period of benefit for deferred contract acquisition costs, the recognition and disclosure of contingent liabilities, income taxes, stock-based compensation, and the fair value of the Company’s common stock and redeemable convertible preferred stock warrants.

Concentration of Credit Risk and Geographic Information

The Company generates revenue from the sale of subscriptions to access its cloud platform and professional services. The Company’s sales team, along with its channel partner network of system integrators and value-added resellers (collectively, “channel partners”), sells the Company’s services worldwide to organizations of all sizes. Due to the nature of the Company’s services and the terms and conditions of the Company’s contracts with its channel partners, the Company’s business could be affected unfavorably if it is not able to continue its relationships with them.

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash, cash equivalents and accounts receivable. The Company’s cash is placed with high-credit-quality financial institutions and issuers, and at times exceed federally insured limits. The Company limits its concentration of risk in cash equivalents and marketable securities by diversifying its investments among a variety of industries and issuers. The Company has not experienced any credit loss relating to its cash equivalents and marketable securities. The Company performs periodic credit evaluations of its customers and generally does not require collateral.

No channel partner or direct customer accounted for 10% or more of the Company’s consolidated accounts receivable as of October 31, 2019. There were no channel partners who accounted for 10% or more of the Company’s consolidated accounts receivable as of January 31, 2019. Outstanding accounts receivable from two of the Company’s direct customers accounted for 10% and 19% of its consolidated accounts receivable as of January 31, 2019.

Revenue from sales to one of the Company’s channel partners accounted for 10% and 15% of its consolidated revenue for the three months ended October 31, 2019 and October 31, 2018, respectively, and 11% and 17% of its consolidated revenue for the nine months ended October 31, 2019 and October 31, 2018, respectively.

There were no direct customers who represented 10% or more of the Company’s total revenue during the three and nine months ended October 31, 2019 and October 31, 2018.

Cash Equivalents and Marketable Securities

The Company considers all highly liquid investments with original maturities of three months or less at date of purchase to be cash equivalents. Cash equivalents as of October 31, 2019 and January 31, 2019 consisted of corporate debt securities and money market funds stated at fair value. The Company classifies investments in marketable securities as available-for-sale securities at the time of purchase. The Company classifies its available-for-sale securities as current or long-term based on the nature of the investments and their availability for use in current operations. Available-for-sale securities are carried at fair value with unrealized gains and losses, if any, included in accumulated other comprehensive income (loss). Unrealized losses are recorded in other income (expense), net, for declines in fair value below the cost of an individual investment that is deemed to be other-than-temporary. The Company did not identify any marketable securities as other-than-temporarily impaired as of October 31, 2019 and January 31, 2019. The Company determines realized gains or losses on the sale of marketable securities on a specific identification method and records such gains or losses in Other income (expense), net. Marketable securities as of October 31, 2019 and January 31, 2019 consisted of corporate debt securities and U.S. treasury securities.

Strategic Investments

In July 2019, the Company agreed to commit up to $10.0 million to a newly formed entity, CrowdStrike Falcon Fund LLC (“Falcon Fund”) in exchange for 50% of the sharing percentage of any distribution by Falcon Fund. Entities associated with Accel, a holder of more than 5% of the Company’s capital stock, also agreed to commit up to $10.0 million to Falcon Fund, and collectively own the remaining 50% of the sharing percentage of Falcon Fund. Falcon Fund is in the business of purchasing, selling, investing and trading in minority equity and convertible debt securities of privately-held companies that develop applications that have potential for substantial contribution to CrowdStrike and its platform. The Company is the manager of the Falcon Fund and controls the investment decisions and day-to-day operations and accordingly will consolidate the Falcon Fund. Falcon Fund has a duration of ten years and may be extended for three additional years. At dissolution, Falcon Fund will be liquidated and the remaining assets will be distributed to the investors based on their respective sharing percentage. As of October 31, 2019, neither the Company nor Accel had made a contribution to Falcon Fund and Falcon Fund had no net assets or operating activities. The Company has elected the measurement alternative for the non-marketable equity investments of the Falcon Fund. Under the measurement alternative, the equity investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The non-marketable equity investments of the Falcon Fund will be valued using significant unobservable inputs or data in inactive markets which require judgment due to the absence of market prices and inherent lack of liquidity. As a result, there could be volatility in the Company’s consolidated statements of operations in future periods due to the valuation and timing of identical or similar investments of the same issuer.

Fair Value of Financial Instruments

The Company’s financial instruments consist of cash equivalents, marketable securities, accounts receivable, accounts payable, accrued expenses, and redeemable convertible preferred stock warrant liability. The carrying values of cash equivalents, accounts receivable, accounts payable, and accrued expenses approximate fair value due to their short-term nature. Refer to Note 3, Fair Value Measurements and Marketable Securities regarding the fair value of the Company’s marketable securities.

The Company reports the redeemable convertible preferred stock warrant liability at fair value (see Note 3, Fair Value Measurements). The warrants issued by the Company for redeemable convertible preferred stock in January 2015, December 2016, and March 2017 (see Note 7, Redeemable Convertible Preferred Stock) have been recorded as a liability based on “Level 3” inputs, which consist of unobservable inputs and reflect management’s estimates of assumptions that market participants would use in pricing the liability. The fair value of the warrants was determined using the Black-Scholes option-pricing model, which is affected by changes in inputs to that model including the Company’s stock price, expected stock price volatility, risk-free rate, and contractual term. Immediately prior to the closing of the IPO on June 14, 2019, the redeemable convertible preferred stock warrants converted into 336,386 warrants to purchase Class B common stock on a one-to-one basis. The redeemable convertible preferred stock warrant liability was reclassified to additional paid-in capital.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are recorded at the invoiced amount and are non-interest bearing. Accounts receivable are stated at their net realizable value, net of an allowance for doubtful accounts. The Company has a well-established collections history from its customers. Credit is extended to customers based on an evaluation of their financial condition and other factors. The Company generally does not require collateral from its customers; however, the Company may require payment prior to commencing service in certain instances to limit credit risk. The Company records an allowance for doubtful accounts based on management’s assessment of the collectability of accounts. Management regularly reviews the adequacy of the allowance for doubtful accounts by considering the age of each outstanding invoice, each customer’s expected ability to pay, and the collection history with each customer, when applicable, to determine whether the allowance is appropriate. Amounts deemed uncollectible are written off against the allowance for doubtful accounts. As of October 31, 2019 and January 31, 2019, the allowance for doubtful accounts was $1.4 million and $1.0 million, respectively.

Deferred Offering Costs

Deferred offering costs of $2.9 million have been recorded as other assets on the condensed consolidated balance sheet as of January 31, 2019, and consist of expenses incurred in connection with the Company’s IPO, including legal, accounting, printing, and other IPO-related costs. Subsequent to January 31, 2019, the Company capitalized an additional $3.0 million of offering costs. Upon the close of the IPO on June 14, 2019, all of these deferred offering costs were reclassified to stockholders’ equity and recorded against the proceeds from the offering. As of October 31, 2019, the Company had paid all $5.9 million of these deferred offering costs.

Property and Equipment, Net

Property and equipment, net, is stated at historical cost less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line method over the estimated useful lives of the assets as follows:


Data center and other computer equipment			3 - 5 years
Furniture and equipment			5 years
Purchased software			3 - 5 years
Capitalized internal-use software			3 years
Leasehold improvements			Estimated useful life or term of the lease, whichever is shorter

Expenditures for routine maintenance and repairs are charged to operating expense as incurred. Major renewals and improvements are capitalized and depreciated over their estimated useful lives. Upon retirement or other disposition of property and equipment, the cost and accumulated depreciation are removed from the accounts, and any gain or loss is recorded in operating expenses in the condensed consolidated statements of operations.

Capitalized Internal-Use Software

The Company capitalizes certain development costs incurred in connection with its internal-use software. These capitalized costs are primarily related to the Company’s cloud-delivered solution for next-generation endpoint protection. Costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, internal and external costs, if direct, are capitalized until the software is substantially complete and ready for its intended use. Capitalization ceases upon completion of all substantial testing. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Capitalized costs are recorded as property and equipment, net. Maintenance and training costs are expensed as incurred. Internal-use software is amortized to cost of revenue on a straight-line basis over its estimated useful life of three years. Management evaluates the useful lives of these assets on an annual basis and tests for impairment whenever events or changes in circumstances occur that could impact the recoverability of these assets. There were no impairments of internal-use software during the three months ended October 31, 2019 and October 31, 2018. The Company capitalized $2.2 million and $1.8 million in internal-use software during the three months ended October 31, 2019 and October 31, 2018, respectively, and $5.7 million and $5.0 million during the nine months ended October 31, 2019 and October 31, 2018, respectively. Amortization expense associated with internal-use software totaled $1.6 million and $1.2 million during the three months ended October 31, 2019 and October 31, 2018, respectively, and $4.6 million and $3.5 million during the nine months ended October 31, 2019 and October 31, 2018, respectively. The net book value of capitalized internal-use software was $12.6 million and $11.5 million as of October 31, 2019 and January 31, 2019, respectively.

Intangible Assets, Net

Intangible assets, net, consisting of developed technology, customer relationships, and non-compete agreements, are stated at cost less accumulated amortization. All intangible assets have been determined to have definite lives and are amortized on a straight-line basis over their estimated economic lives of three to five years. Amortization expense related to developed technology is included in cost of revenue, amortization expense related to customer relationships is included in sales and marketing expenses, and amortization expense related to non-compete agreements is included in research and development expenses.

Deferred Contract Acquisition Costs

The Company capitalizes contract acquisition costs that are incremental to the acquisition of customer contracts. Contract acquisition costs are accrued and capitalized upon execution of the sales contract by the customer. Sales commissions for renewal of a contract are not considered commensurate with the commissions paid for the acquisition of the initial contract or follow-on upsell given the substantive difference in commission rates in proportion to their respective contract values. Commissions, including referral fees paid to channel partners, paid upon the initial acquisition of a contract or subsequent upsell are amortized over an estimated period of benefit of four years while commissions paid for renewal contracts are amortized over the contractual term of the renewals. Sales commissions associated with professional service contract are amortized ratably over an estimated period of benefit of six months. The Company capitalized contract acquisition costs of $27.4 million, which is under ASC606, and $13.2 million, which is under ASC 605, during the three months ended October 31, 2019 and October 31, 2018, respectively, and $55.2 million, which is under ASC 606, and $27.5 million, which is under ASC 605, during the nine months ended October 31, 2019 and October 31, 2018, respectively. Contract acquisition cost amortization expense was $9.0 million, which is under ASC 606, and $7.3 million, which was under ASC 605, during the three months ended October 31, 2019 and October 31, 2018, respectively, and $24.1 million, which is under ASC 606, and $19.3 million, which was under ASC 605, during the nine months ended October 31, 2019 and October 31, 2018, respectively.

Impairment of Long-Lived Assets

The Company reviews for impairment of long-lived assets whenever events or changes in circumstances indicate that the carrying amount of the asset (or asset group) may not be recoverable. Events and changes in circumstances considered by the Company in determining whether the carrying value of long-lived assets may not be recoverable, include, but are not limited to: significant changes in performance relative to expected operating results, significant changes in the use of the assets, significant negative industry or economic trends, and changes in the Company’s business strategy. Impairment testing is performed at an asset level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities (an “asset group”). An impairment loss would be recognized when estimated future cash flows expected to result from the use of the asset (or asset group) and its eventual disposition is less than its carrying amount. No impairment indicators were identified by the Company and no impairment losses were recorded by the Company during the three and nine months ended October 31, 2019 and October 31, 2018.

Deferred Revenue

The deferred revenue balance consists of subscription and professional services which have been invoiced upfront and are recognized as revenue only when the revenue recognition criteria are met. The Company typically invoices its customers at the beginning of the term, or in some instances, such as in multi-year arrangements, in installments. Professional services are either invoiced upfront, invoiced in installments, or invoiced as the services are performed. Accordingly, the Company’s deferred revenue balance does not include revenues for future years of multi-year non-cancellable contracts that have not yet been billed.

The Company recognizes subscription revenue ratably over the contract term beginning on the commencement date of each contract, the date that services are made available to customers. Once services are available to customers, the Company records amounts due in accounts receivable and in deferred revenue. To the extent the Company bills customers in advance of the contract commencement date, the accounts receivable and corresponding deferred revenue amounts are netted to zero on the condensed consolidated balance sheets, unless such amounts have been paid as of the balance sheet date.

Redeemable Convertible Preferred Stock Warrants

Warrants related to the Company’s redeemable convertible preferred stock are classified as liabilities on the Company’s consolidated balance sheet. The warrants are subject to reassessment at each balance sheet date, and any change in fair value is recognized as a component of Other income (expense), net, in the condensed consolidated statements of operations. The Company will continue to adjust the liability for changes in fair value until the earlier of the expiration or exercise of the warrants, or upon their automatic conversion into warrants to purchase common stock in connection with a qualified initial public offering (as defined in Note 7, Redeemable Convertible Preferred Stock) such that they qualify for equity classification and no further remeasurement is required.

Immediately prior to the closing of the IPO on June 14, 2019, the redeemable convertible preferred stock warrants converted into 336,386 warrants to purchase Class B common stock on a one-to-one basis. The redeemable convertible preferred stock warrant liability was reclassified to additional paid-in capital. Within the same month, the Company received notice from the holders of 336,386 warrants as to their intentions to exercise the warrants for shares of common stock of the Company. Such shares were settled via net settlement method, which was elected by the holders to reduce the number of shares issued upon exercise to reflect net settlement of the exercise price, resulting in the issuance of 322,278 shares of the Company’s common stock.

Revenue Recognition – ASC 606

The Company adopted ASC 606 on February 1, 2019, using the modified retrospective transition method. Under this method, results for reporting periods beginning on February 1, 2019 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with prior accounting under Topic 605. The Company has shown the effect of applying ASC 606 for the three months ended October 31, 2019 and the nine months ended October 31, 2019 in the disclosures below.

The following table summarizes cumulative effect of changes from the adoption of Topic 606 on the Company’s Condensed Consolidated Balance Sheets as of February 1, 2019:

The adoption of Topic 606 had no impact on net cash provided by or used in operating, investing, or financing activities in the Company’s condensed consolidated statement of cash flows for the three or nine months ended October 31, 2019.

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 the core principle of this standard, the Company applies the following five steps:

1)Identify the contract with a customer

The Company considers the terms and conditions of contracts with customers and its customary business practices in identifying contracts under ASC 606. The Company determines it has a contract with a customer when the contract is approved, each party’s rights regarding the services to be transferred can be identified, payment terms for the services can be identified, it has been determined that the customer has the ability and intent to pay, and the contract has commercial substance. The Company applies judgment in determining the customer’s ability and intent to pay, 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 pertaining 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 from the Company or from third parties, 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 obligations consist of (i) subscriptions and (ii) professional services.

3)Determine the transaction price

The transaction price is determined based on the consideration which the Company is expected to be entitled to in exchange for transferring services to the customer. Variable consideration is included in the transaction price if it is probable that a significant future reversal of cumulative revenue under the contract will not occur. None of the Company’s contracts contain a significant financing component.

4)Allocate the transaction price to performance obligations in the contract

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”).

5)Recognize revenue when or as performance obligations are satisfied

Revenue is recognized at the time the related performance obligation is satisfied by transferring the promised service to the customer. Revenue is recognized when control of the services is transferred to the customer, in an amount that reflects the consideration expected to be received in exchange for those services. The Company generates all its revenue from contracts with customers.

Subscription Revenue

The Company’s Falcon Platform technology solutions are subscription, software as a service (“SaaS”) offerings designed to continuously monitor, share, and mitigate risks from determined attackers. Customers do not have the right to take possession of the cloud-based software platform. Fees are based on several factors, including the solutions subscribed for by the customer and the number of endpoints purchased by the customer. The subscription fees are typically payable within 30 to 60 days after the execution of the arrangement, and thereafter upon renewal or subsequent installment. The Company initially records the subscription fees as deferred revenue and recognizes revenue on a straight-line basis over the term of the agreement.

The typical subscription term is one to three years. Most of the Company’s contracts 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. Some customers have the option to purchase additional subscription at a stated price. These options generally do not provide a material right as they are priced at our SSP.

Professional Services Revenue

The Company offers several types of professional services including incident response and forensic services, surge forensic and malware analysis, and attribution analysis, which are focused on responding to imminent and direct threats, assessing vulnerabilities, and recommending solutions. These services are distinct from subscription services. Professional services do not result in significant customization of the subscription service. The professional services are available through hourly rate and fixed fee contracts, one-time and ongoing engagements, and retainer-based agreements. Revenue for time and materials arrangements is recognized as services are performed and revenue for fixed fees is recognized on a proportional performance basis as the services are performed.

Contracts with Multiple Performance Obligations

Some contracts with customers contain multiple promised services consisting of subscription and professional services that are distinct and accounted for separately. The transaction price is allocated to the separate performance obligations on a relative SSP basis. The SSP is the price at which the Company would sell promised subscription or professional services separately to a customer. Judgment is required to determine the SSP for each distinct performance obligation. The Company determines SSP based on its overall pricing objectives, taking into consideration the type of subscription or professional service and the number of endpoints.

Variable Consideration

Revenue from sales is recorded at the net sales price, which is the transaction price, and includes estimates of variable consideration. The amount of variable consideration that is included in the transaction price is constrained and is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue will not occur when the uncertainty is resolved.

If subscriptions do not meet certain service level commitments, the Company’s customers are entitled to receive service credits, and in certain cases, refunds, each representing a form of variable consideration. The Company has historically not experienced any significant incidents affecting the defined levels of reliability and performance as required by its subscription contracts. Accordingly, any estimated refunds related to these agreements in the condensed consolidated financial statements is not material during the periods presented.

The Company provides rebates and other credits within its contracts with certain resellers, which are estimated based on the most likely amounts expected to be earned or claimed on the related sales transaction. Overall, the transaction price is reduced to reflect the Company’s estimate of the amount of consideration to which it is entitled based on the terms of the contract. Estimated rebates and other credits were not material during the periods presented.

Revenue Recognition – ASC 605

Prior to adopting ASC 606 on February 1, 2019, the Company recognized subscription and professional services when: (1) persuasive evidence of the contract exists in the form of a written contract, amendments to that contract, or purchase orders from a third party; (2) delivery has occurred, or services have been rendered; (3) the price is fixed or determinable; and (4) collectability is reasonably assured based on customer creditworthiness and history of collection.

The timing and the amount the Company recognized as revenue was determined based on the facts and circumstances of each customer’s arrangements. Evidence of an arrangement consisted of a signed customer agreement. The Company considered that the delivery of its solution had commenced once it provided the customer with log-in information and the term of the contract had started. Fees were fixed based on stated rates specified in the customer agreement. The Company assessed collectability based on several factors, including the credit worthiness of the customer and transaction history. If collectability was not reasonably assured, revenue was deferred until the fees were collected.

For arrangements that involve the contemporaneous sale of subscription and professional services, the Company applied the multiple-element arrangement guidance to allocate the arrangement consideration to all deliverables based on their relative selling price. The Company determined that the cloud-based platform subscription has standalone value, because once access is given to the customer, the solutions are fully functional and do not require any additional development, modification, or customization. Professional services have standalone value because they are regularly sold by the Company in separate transactions. Additionally, the performance of these professional services generally does not require highly specialized or technologically skilled individuals and the professional services are not essential to the functionality of the solutions.

The Company used a hierarchy to determine the selling price to be used for allocating revenue to deliverables: (i) vendor-specific objective evidence of fair value (“VSOE”); (ii) third-party evidence of selling price (“TPE”); and (iii) best estimate of selling price (“BESP”). BESP reflected the Company’s best estimates of what the selling prices of elements would be if they were sold regularly on a stand-alone basis. The Company’s process for determining BESP involved management’s judgment and considered numerous factors including the nature of the deliverables themselves and historical discounting practices. The Company updated its estimates of BESP on an ongoing basis as events and circumstances required.

Research and Development Expense

Research and development costs are expensed when incurred, except for certain internal-use software development costs, which may be capitalized as noted above. Research and development expenses consist primarily of personnel and related headcount costs, costs of professional services associated with the ongoing development of the Company’s technology, and allocated overhead.

Advertising

All advertising costs are expensed as incurred and are included in sales and marketing expense in the condensed consolidated statements of operations. The Company incurred $2.2 million and $1.5 million of advertising costs during the three months ended October 31, 2019 and October 31, 2018, respectively, and $5.5 million and $2.6 million during the nine months ended October 31, 2019 and October 31, 2018, respectively.

Stock-Based Compensation

The Company accounts for stock-based awards granted to employees and directors based on the awards’ estimated grant date fair value. The Company estimates the fair value of its stock options using the Black-Scholes option-pricing model. The resulting fair value is recognized on a straight-line basis over the period during which the employee or director is required to provide service in exchange for the award, usually the vesting period, which is generally four years. The Company accounts for forfeitures as they occur.

Prior to the Company’s adoption of ASU 2018-07, stock-based awards issued to non-employees were accounted for at fair value determined by using the Black-Scholes option-pricing model. The Company believes that the fair value of the stock options is more reliably measured than the fair value of the services received. The fair value of each non-employee stock-based award is remeasured each period until a commitment date is reached, which is generally the vesting date. The Company early adopted ASU 2018-07 on February 1, 2019 and began accounting for stock-based awards issued to non-employees the same as it accounts for stock-based awards issued to employees. The effect on the Company’s condensed consolidated financial statements for the three and nine months ended October 31, 2019 was not material.

Restricted stock units (“RSUs”) granted under the 2011 Plan are subject to a service-based vesting condition and a performance-based vesting condition. The service-based vesting condition is generally satisfied based on one of three vesting schedules: (i) vesting of one-fourth of the RSUs on the first “Company vest date” (defined as March 20, June 20, September 20, or December 20) on or following the one-year anniversary of the vesting commencement date with the remainder of the RSUs vesting in twelve equal quarterly installments thereafter, subject to continued service, (ii) vesting in sixteen equal quarterly installments beginning on December 20, 2018, subject to continued service, or (iii) vesting in eight equal quarterly installments beginning on December 20, 2022, subject to continued service. The performance-based vesting condition is satisfied on the earlier of (i) a change in control, in which the consideration paid to holders of shares is either cash, publicly traded securities, or a combination thereof, or (ii) the first Company vest date to occur following the expiration of the lock-up period upon an IPO, subject to continued service through such change in control or lock-up expiration, as applicable. None of the RSUs vest unless the performance-based vesting condition is satisfied. Upon the completion of the IPO, the performance-based vesting condition was met and the Company recognized $17.3 million of deferred expense related to RSUs as of that date in its condensed consolidated statement of operations.

Performance-based stock units (“PSUs”) granted under the 2019 Plan are subject to a performance-based vesting condition. With regard to the performance conditions, the fair value of new or modified awards is equal to the grant date fair market value of the Company’s common stock. PSUs generally vest over a four-year period based on the achievement of specified performance targets for the fiscal year ended January 31, 2020 and subject to continued service through the applicable vesting dates. The compensation cost is recognized over the requisite service period when it is probable that the performance condition will be satisfied. Based on the extent to which the performance targets are achieved, shares ultimately awarded may range from 80% to 100% of the target award amount. If the performance targets are below 80%, no shares will be awarded.

Business Combinations

The Company allocates 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, 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, the Company 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 in the condensed consolidated statement of operations.

Goodwill and Intangible Assets

The Company evaluates and tests the recoverability of goodwill for impairment at least annually, on January 31, or more frequently if circumstances indicate that goodwill may not be recoverable. The Company performs the impairment testing by first assessing qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of its reporting unit is less than its carrying amount. The Company has one reporting unit. If, after assessing the totality of events or circumstances, the Company determines it is more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company performs the first step of a two-step analysis by comparing the book value of net assets to the fair value of the reporting unit. To calculate any potential impairment, the Company compares the fair value of a reporting unit with its carrying amount, including goodwill. Any excess of the carrying amount of the reporting unit’s goodwill over its fair value is recognized as an impairment loss, and the carrying value of goodwill is written down. In assessing the qualitative factors, the Company considers the impact of certain key factors including macroeconomic conditions, industry and market considerations, management turnover, changes in regulation, litigation matters, changes in enterprise value, and overall financial performance. No impairment was recorded during the three and nine months ended October 31, 2019 or October 31, 2018. The change in the goodwill balance during the three and nine months ended October 31, 2019 and October 31, 2018 was due to changes in foreign currency exchange rates.

Acquired intangible assets consisting of identifiable intangible assets, were comprised of developed technology, customer relationships, and non-compete agreements resulting from acquisitions. Acquired intangible assets are recorded at fair value on the date of acquisition and amortized over their estimated economic lives following the pattern in which the economic benefits of the assets will be consumed which is on a straight-line basis. Acquired intangible assets are presented net of accumulated amortization on the condensed consolidated balance sheets. The Company reviews the carrying amounts of intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. The Company measures the recoverability of intangible assets by comparing the carrying amount of each asset to the future undiscounted cash flows it expects the asset to generate. If the Company considers any of these assets to be impaired, the impairment to be recognized equals the amount by which the carrying value of the asset exceeds its fair value. In addition, the Company periodically evaluates the estimated remaining useful lives of long-lived assets to determine whether events or changes in circumstances warrant a revision to the remaining period of depreciation or amortization.

Leases

The Company leases its office space under various noncancelable operating lease agreements and recognizes related rent expense on a straight-line basis over the term of the lease. Certain lease agreements contain rent holidays, scheduled rent increases, lease incentives, and renewal options. Rent holidays and scheduled rent increases are included in the determination of rent expense to be recorded over the lease term. Lease incentives are recognized as a reduction of rent expense on a straight-line basis over the term of the lease. Renewals are not assumed in the determination of the lease term unless they are deemed to be reasonably assured at the inception of the lease. The Company begins to recognize rent expense on the date that the Company obtains the legal right to use and control the leased space.

Foreign Currency Translation

The functional currencies of the Company’s foreign subsidiaries are each country’s local currency. Assets and liabilities of the subsidiaries are translated into U.S. Dollars at exchange rates in effect at the reporting date. Amounts classified in stockholders’ equity/(deficit) are translated at historical exchange rates. Revenue and expenses are translated at the average exchange rates during the period. The resulting translation adjustments are recorded in accumulated other comprehensive income (loss). Foreign currency transaction gains or losses, whether realized or unrealized, are reflected in the condensed consolidated statements of operations within Other income (expense), net, and have not been material for all periods presented.

Income Taxes

The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between the financial statement and tax basis of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.

The Company accounts for unrecognized tax benefits using a more-likely-than-not threshold for financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. The Company establishes a liability for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. The Company records an income tax liability, if any, for the difference between the benefit recognized and measured and the tax position taken or expected to be taken on the Company’s tax returns. To the extent that the assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is made. The liability is adjusted considering changing facts and circumstances, such as the outcome of a tax audit. The provision for income taxes includes the impact of liability provisions and changes to the liability that are considered appropriate. As the Company maintains a full valuation allowance against its deferred tax assets, the changes resulted in no additional tax expense during the three and nine months ended October 31, 2019 or October 31, 2018. As of October 31, 2019, the Company does not expect that changes in the liability for unrecognized tax benefits for the next twelve months will have a material impact on its condensed consolidated financial statements.

Sales Taxes

When sales and other taxes are billed, such amounts are recorded as accounts receivable with a corresponding increase to other current liabilities, respectively. The balances are then removed from the condensed consolidated balance sheet as cash is collected from the customer and as remitted to the respective tax authority.

Segment and Geographic Information

The Company’s chief operating decision maker (“CODM”) is its chief executive officer. The CODM reviews financial information presented on a consolidated basis for the purposes of allocating resources and evaluating financial performance. Accordingly, management has determined that the Company operates as one operating and reportable segment. The Company presents financial information about its geographic areas in Note 12 to the condensed consolidated financial statements.

Net Loss per Share

The Company computes basic and diluted net loss per share attributable to common stockholders for Class A and Class B common stock using the two-class method required for participating securities. The Company considers all series of its redeemable convertible preferred stock to be participating securities. Net loss is attributed to Class A and Class B common stock based on their participation rights. Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period.

Diluted earnings per share attributable to common stockholders adjusts basic earnings per share for the potentially dilutive impact of stock options and redeemable convertible preferred stock. As the Company has reported losses for all periods presented, all potentially dilutive securities including redeemable convertible preferred stock, stock options, and warrants, are antidilutive and accordingly, basic net loss per share equals diluted net loss per share.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides guidance for revenue recognition. Under the new guidance, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. In addition, the guidance requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Subsequently, the FASB has issued the following guidance to amend ASU 2014-09: ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date; ASU No. 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net); ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing; ASU No. 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients; and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, which clarifies narrow aspects of Topic 606 or corrects unintended application of the guidance. The Company must adopt ASU No. 2015-14, ASU No. 2016-08, ASU No. 2016-10, ASU No. 2016-12, and ASU No. 2016-20 with ASU No. 2014-09, which are referred to collectively as the “new revenue guidance.” On February 1, 2019, the Company adopted ASU No. 2014-09 using the modified retrospective transition method. Under this method, results for reporting periods beginning on February 1, 2019 are presented under Topic 606, while prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under Topic 605. The Company recorded a cumulative effect adjustment to the opening accumulated deficit of $23.4 million, net of tax, as of the date of adoption. The change resulted from a $23.7 million reduction in commissions expense that the Company capitalized under Topic 606, but would have been recognized during the prior period as commissions expense under its historical accounting practices under Topic 605 and a $0.3 million reduction in revenue that would have been recognized during the prior period under Topic 605.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which changes the definition of a business to assist entities with evaluating when a set of transferred assets and activities is a business. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, the set of transferred assets and activities is not a business. On February 1, 2019, the Company adopted ASU No. 2018-07, which did not have a material effect on the Company’s condensed consolidated financial statements.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This ASU simplifies the accounting for share-based payments to nonemployees by aligning it with the accounting for share-based payments to employees, with certain exceptions. This ASU is effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. For all other entities, this ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. Early adoption is permitted, but no earlier than the adoption date of Topic 606. On February 1, 2019, the Company adopted ASU No. 2018-07, which did not have a material effect on the Company’s condensed consolidated financial statements.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification. This release amends certain disclosure requirements that have become redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders’ equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. The final rule was effective November 5, 2018. The Company adopted this amendment as of February 1, 2019, including presenting the activity of the stockholder’s equity accounts in the accompanying Condensed Consolidated Statements of Redeemable Convertible Preferred Stock and Stockholders’ Equity (Deficit) for the periods presented.

Recently Issued Accounting Pronouncements

Under the JOBS Act, the Company meets the definition of an emerging growth company. The Company has elected to use the extended transition period for complying with new or revised accounting standards pursuant to Section 107(b) of the JOBS Act.

In February 2016, the FASB issued ASU No. 2016-02, Leases. The new guidance supersedes current guidance related to accounting for leases and generally requires an entity to recognize on its balance sheet operating and financing lease liabilities and corresponding right-of-use assets. In July 2018, the FASB issued ASU No. 2018-10, Codification Improvements to Topic 842. This ASU makes 16 technical corrections to the new lease standard and other accounting topics, alleviating unintended consequences from applying the new standard. It does not make any substantive changes to the core provisions or principles of the new standard. In July 2018, the FASB also issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements. This ASU provides (1) an optional transition method that entities can use when adopting the standard and (2) a practical expedient that permits lessors to not separate non-lease components from the associated lease component if certain conditions are met. As an emerging growth company as defined in the JOBS Act, the Company has elected to delay adoption of this ASU until February 1, 2020. ASU No. 2016-02 can be adopted using either full or modified retrospective approach as of the earliest period presented or as of the adoption date with the cumulative effect adjustment to the opening balance recognized in retained earnings in the period of adoption. The Company is currently evaluating the potential impact of these ASUs on its consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU amends guidance on reporting credit losses for assets held at amortized cost basis and available-for-sale debt securities to require that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. In May 2019, the FASB issued an update for ASU No. 2016-13. The standard replaces the existing incurred loss model with an expected credit loss model for financial assets measured at amortized cost, including trade receivables, and requires that credit losses on available-for-sale debt securities be presented as an allowance rather than as a write-down. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the consolidated statements of operations. For public business entities that are SEC filers, this ASU is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. For all other entities, this ASU is effective for fiscal years beginning after December 15, 2020, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This ASU simplifies the measurement of goodwill by eliminating step two of the two-step impairment test. Step two measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. This ASU requires an entity to compare the fair value of a 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. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. As an emerging growth company defined in the JOBS Act, the Company has elected to delay adoption of this ASU until February 1, 2022. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. As an emerging growth company as defined in the JOBS Act, the Company has elected to delay adoption of this ASU until February 1, 2020. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force). This ASU aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software. As an emerging growth company defined in the JOBS Act, the Company has elected to delay adoption of this ASU until February 1, 2021. Entities can choose to adopt this ASU prospectively or retrospectively. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements.

Fair Value Measurements and Marketable Securities

3. Fair Value Measurements and Marketable Securities

The Company follows ASC 820, Fair Value Measurements, with respect to marketable securities that are measured at fair value on a recurring basis. Under the standard, fair value is defined as the exit price, or the amount that would be received to sell an asset or a liability in an orderly transaction between market participants as of the measurement date. The standard also establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use in valuing the asset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect the Company’s assumptions about the factors market participants would use in valuing the asset or liability developed based upon the best information available in the circumstances.

The hierarchy is broken down into three levels as follows:

Level 1 Assets and liabilities whose values are based on unadjusted quoted market prices for identical assets and liabilities in active markets

Level 2 Assets and liabilities whose values are based on quoted prices in markets that are not active or inputs that are observable for substantially the full term of the asset or liability

Level 3 Assets and liabilities whose values are based on prices or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement

Categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

The Company’s fair value hierarchy for its financial assets and liabilities that are measured at fair value on a recurring basis are as follows:


	October 31, 2019														January 31, 2019

__________________________________

(1)Included in “Cash and cash equivalents” on the condensed consolidated balance sheets.

(2)The contingent consideration consists of development milestone payments. The fair value of the contingent consideration was estimated by developing the risk-adjusted discounted value as well as discounted probability-weighted expected payments. That measure is based on Level 3 inputs which are significant inputs that are not observable in the market. Key assumptions at the acquisition date included (a) a discount rate range of 3%-3.02% and (b) three probability-adjusted milestone payments, each $0.2 million. As of January 31, 2019, the first milestone payment of $0.2 million had been made. During the three months ended April 30, 2019, the remaining milestones were deemed not probable of being paid and the remaining contingent consideration of $0.5 million was written off to Other income (expense), net.

(3)Immediately prior to the closing of the IPO on June 14, 2019, the redeemable convertible preferred stock warrants converted into 336,386 warrants to purchase Class B common stock on a one-to-one basis. The redeemable convertible preferred stock warrant liability was reclassified to additional paid-in capital. Within the same month, the Company received notice from the holders of 336,386 warrants as to their intentions to exercise the warrants for shares of common stock of the Company. Such shares were settled via net settlement method, which was elected by the holders to reduce the number of shares issued upon exercise to reflect net settlement of the exercise price, resulting in the issuance of 322,278 shares of the Company’s common stock.

There were no transfers between the levels of the fair value hierarchy during the three and nine months ended October 31, 2019 or October 31, 2018.

At October 31, 2019 and January 31, 2019, the amortized cost of the Company’s cash equivalents and marketable securities approximated their fair value and there were no material realized or unrealized gains or losses, either individually or in the aggregate. In addition, the securities that had been in continuous unrealized loss position per security type and in aggregate are not material as of October 31, 2019 and January 31, 2019. There were no impairments considered “other-than-temporary” as it is more likely than not the Company will hold the securities until maturity or a recovery of the cost basis.

The remaining contractual maturities of marketable securities as of October 31, 2019 and January 31, 2019 were less than one year.

The following summarizes the changes in the redeemable convertible preferred stock warrant liability, which is classified as a Level 3 instrument:


	Three Months Ended October 31,						Nine Months Ended October 31,
	2019		2018		2019		2018
	(in thousands)						(in thousands)
Balance at beginning of period	$	—	$	3,016	$	4,537	$	961
Adjustment resulting from change in fair value recognized in the condensed consolidated statements of operations	—		880		6,022		2,935
Reclassification of liability for redeemable convertible preferred stock warrants to additional paid-in capital upon initial public offering	—		—		(10,559)		—
Balance at end of period	$	—	$	3,896	$	—	$	3,896

The fair value of the redeemable convertible preferred stock warrant liability was estimated using the Black-Scholes option-pricing model and was based on significant inputs not observable in the market, and therefore was classified as a Level 3 instrument. The inputs include the Company’s preferred stock price, expected stock price volatility, risk-free interest rate, and contractual term. No loss and a loss of $0.9 million was recorded as a component of Other income (expense), net, relating to the final remeasurement of the redeemable convertible preferred stock warrant liability during the three months ended October 31, 2019 and October 31, 2018, respectively, and a loss of $6.0 million and $2.9 million during the nine months ended October 31, 2019 and October 31, 2018, respectively.

Secured Revolving Credit Facility	9 Months Ended
Secured Revolving Credit Facility	Oct. 31, 2019
Debt Disclosure [Abstract]
Secured Revolving Credit Facility	5. Secured Revolving Credit Facility In April 2019, the Company entered into a Credit Agreement with Silicon Valley Bank and other lenders, to provide a revolving line of credit of up to $150.0 million, including a letter of credit sub-facility in the aggregate amount of $10.0 million, and a swingline sub-facility in the aggregate amount of $10.0 million. The Company also has the option to request an incremental facility of up to an additional $75.0 million from one or more of the lenders under the Credit Agreement. The amount the Company may borrow under the Credit Agreement may not exceed the lesser of $150.0 million or the Company’s ordinary course recurring subscription revenue for the most recent month, as determined under the Credit Agreement, multiplied by a number that is (i) 6, for the first year after entry into the Credit Agreement; (ii) 5, for the second year after entry into the Credit Agreement; and (iii) 4, thereafter. Under the terms of the Credit Agreement, revolving loans may be either Eurodollar Loans or ABR Loans. Outstanding Eurodollar Loans incur interest at the Eurodollar Rate, which is defined in the Credit Agreement as LIBOR (or any successor thereto), plus a margin between 2.50% and 3.00%, depending on usage. Outstanding ABR Loans incur interest at the highest of (a) the Prime Rate, as published by the Wall Street Journal, (b) the federal funds rate in effect for such day plus 0.50%, and (c) the Eurodollar Rate plus 1.00%, in each case plus a margin between 1.50% and 2.00%, depending on usage. The Company will be charged a commitment fee of 0.2% to 0.3% per year for committed but unused amounts. The Credit Agreement will terminate on April 19, 2022.

Share-based Payment Arrangement [Abstract]

Stock-Based Compensation

9. Stock-Based Compensation

Stock Incentive Plan

In May 2019, the Company’s board of directors adopted, and the stockholders approved the CrowdStrike Holdings, Inc. 2019 Equity Incentive Plan (the “2019 Plan”) with the purpose of granting stock-based awards to employees, directors, officers and consultants, including stock options, restricted stock awards, restricted stock units and performance-based restricted stock units. A total of 8,750,000 shares of Class A common stock were initially available for issuance under the 2019 Plan. The Company’s compensation committee administers the 2019 Plan. The number of shares of our common stock available for issuance under the 2019 Plan is subject to an annual increase on the first day of each fiscal year beginning on February 1, 2020, equal to the lesser of: (i) two percent (2.0%) of outstanding shares of the Company’s capital stock as of the last day of the immediately preceding fiscal year or (ii) such other amount as our board of directors may determine.

The 2011 Plan was terminated on June 10, 2019, which was the business day prior to the effectiveness of the Company’s registration statement on Form S-1 used in connection with the Company’s IPO, and stock-based awards are no longer granted under the 2011 Plan. Any shares underlying stock options that expire or terminate or are forfeited or repurchased under the 2011 Plan will be automatically transferred to the 2019 Plan.

Stock Options

The Company records compensation expense for employee stock options based on the estimated fair value of the options on the date of grant using the Black-Scholes option-pricing model with the assumptions included in the table below. The expected term represents the period that the Company’s share-based awards are expected to be outstanding. The expected term assumptions were determined based on the vesting terms, exercise terms, and contractual lives of the options. The expected stock price volatility is based upon comparable public company data. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the estimated option life.

The fair value of each option was estimated on the date of grant using the following assumptions during the period:


	Nine Months Ended October 31,
	2019	2018

Expected term (in years)	6.05	6.05 - 7.52
Risk-free interest rate	2.0% - 2.4%	2.6% - 3.1%
Expected stock price volatility	37.7% - 37.9%	37.8% - 38.9%
Dividend yield	— %	— %

The following table is a summary of stock option activity for the nine months ended October 31, 2019:


	Number of Shares	Weighted-Average Exercise Price Per Share

Options vested and expected to vest at October 31, 2019	20,701	$	4.55
Options exercisable at October 31, 2019	11,871	$	2.30

Options exercisable include 982,200 options that were unvested as of October 31, 2019.

The aggregate intrinsic value of options vested and exercisable was $608.9 million and $181.1 million as of October 31, 2019 and January 31, 2019, respectively. The weighted-average remaining contractual term of options vested and exercisable was 6.4 years and 7.1 years as of October 31, 2019 and January 31, 2019, respectively.

No options were granted for the three months ended October 31, 2019. The weighted-average grant date fair values of all options granted was $5.81 per share during the three months ended October 31, 2018. The weighted-average grant date fair values of all options granted was $9.51 and $5.59 per share during the nine months ended October 31, 2019 and October 31, 2018, respectively. The total intrinsic value of all options exercised was $17.3 million and $13.4 million during the three months ended October 31, 2019 and October 31, 2018, respectively, and $107.0 million and $21.0 million during the nine months ended October 31, 2019 and October 31, 2018, respectively.

The aggregate intrinsic value of stock options outstanding as of October 31, 2019 and January 31, 2019 was $939.0 million and $286.1 million, respectively, which represents the excess of the fair value of the Company’s common stock over the exercise price of the options multiplied by the number of options outstanding. The weighted-average remaining contractual term of stock options outstanding was 7.3 years and 7.9 years as of October 31, 2019 and January 31, 2019, respectively.

Total unrecognized stock-based compensation expense related to unvested options was $39.1 million as of October 31, 2019. This expense is expected to be amortized on a straight-line basis over a weighted-average vesting period of 2.3 years. Total unrecognized stock-based compensation expense related to unvested options was $45.8 million as of January 31, 2019. This expense is expected to be amortized on a straight-line basis over a weighted-average vesting period of 3.4 years.

Early Exercise of Employee Options

The 2011 Stock Plan allows for the early exercise of stock options for certain individuals as determined by the Board of Directors. The consideration received for an early exercise of an option is a deposit of the exercise price and the related dollar amount is recorded as a liability for early exercise of unvested stock options in the condensed consolidated balance sheets. This liability is reclassified to additional paid-in capital as the awards vest. If a stock option is early exercised, the unvested shares may be repurchased by the Company in case of employment termination or for any reason, including death and disability, at the price paid by the purchaser for such shares. There were no issued shares of common stock related to early exercised stock options for the three months ended October 31, 2019. During the nine months ended October 31, 2019, the Company issued 1,037,356 shares of common stock related to early exercised stock options. As of October 31, 2019, the number of shares of common stock related to early exercised stock options subject to repurchase was 1,127,811 shares for $9.6 million. As of January 31, 2019, the number

of shares of common stock related to early exercised stock options subject to repurchase was 545,941 shares for $1.2 million. Common stock purchased pursuant to an early exercise of stock options is not deemed to be outstanding for accounting purposes until those shares vest. The Company includes unvested shares subject to repurchase in the number of shares outstanding on the statement of redeemable convertible preferred stock and stockholders’ equity (deficit).

Restricted Stock Units

Beginning in September 2018, the Company began issuing RSUs to certain employees. These RSUs include a service-based vesting condition and a performance-based vesting condition. The service-based vesting condition is generally satisfied based on one of three vesting schedules: (i) vesting of one-fourth of the RSUs on the first “Company vest date” (defined as March 20, June 20, September 20, or December 20) on or following the one-year anniversary of the vesting commencement date with the remainder of the RSUs vesting in twelve equal quarterly installments thereafter, subject to continued service, (ii) vesting in sixteen equal quarterly installments beginning on December 20, 2018, subject to continued service, or (iii) vesting in eight equal quarterly installments beginning on December 20, 2022, subject to continued service. The performance-based vesting condition is satisfied on the earlier of (i) a change in control, in which the consideration paid to holders of shares is either cash, publicly traded securities, or a combination thereof, or (ii) the first Company vest date to occur following the expiration of the lock-up period upon an IPO, subject to continued service through such change in control or lock-up expiration, as applicable. None of the RSUs vest unless the performance-based vesting condition is satisfied. Upon the completion of the IPO, the performance-based vesting condition was met and the Company recognized $17.3 million of deferred expense related to RSUs as of that date in its condensed consolidated statement of operations.

Expense for RSUs that have a service-based condition only are being amortized on a straight-line basis. Expense for RSUs that have both a service-based and a performance-based condition are being amortized under the accelerated attribution method. Total unrecognized stock-based compensation expense related to unvested RSUs was $137.5 million as of October 31, 2019. This expense is expected to be amortized (subject to acceleration or straight-line basis) over a weighted-average vesting period of 2.3 years. Total unrecognized stock-based compensation expense related to unvested restricted stock units was $51.9 million as of January 31, 2019. This expense is expected to be amortized on an accelerated attribution method over a weighted-average vesting period of 2.2 years.

Performance-based Stock Units

Performance-based stock units (“PSUs”) granted under the 2019 Plan are subject to a performance-based vesting condition. PSUs generally vest over a four-year period based on the achievement of specified performance targets for the fiscal year ended January 31, 2020 and subject to continued service through the applicable vesting dates. The compensation cost is recognized over the requisite service period when it is probable that the performance condition will be satisfied. Based on the extent to which the performance targets are achieved, shares ultimately awarded may range from 80% to 100% of the target award amount. If the performance targets are below 80%, no shares will be awarded.

Expense for PSUs are being amortized under the accelerated attribution method. Total unrecognized stock-based compensation expense related to unvested PSUs was $3.5 million as of October 31, 2019. This expense is expected to be amortized over a weighted-average vesting period of 1.9 years.

The following table is a summary of RSU and PSU activities for the nine months ended October 31, 2019:


	Number of Shares	Weighted- Average Grant Date Fair Value Per Share

Employee Stock Purchase Plan

In May 2019, the board of directors adopted, and the stockholders approved the CrowdStrike Holdings, Inc. 2019 Employee Stock Purchase Plan (“ESPP”), which became effective on June 10, 2019, which was the business day prior to the effectiveness of the Company’s registration statement on Form S-1 used in connection with the Company’s IPO. A total of 3,500,000 shares of Class A common stock were initially reserved for issuance under the ESPP. The Company’s compensation committee administers the ESPP. The number of shares of common stock available for issuance under the ESPP is subject to an annual increase on the first day of each fiscal year beginning on February 1, 2020, equal to the lesser of: (i) one percent (1%) of outstanding shares of the Company’s capital stock as of the last day of the immediately preceding fiscal year or (ii) such other amount as its board of directors may determine.

The ESPP provides for consecutive offering periods that will typically have a duration of approximately 24 months in length and is comprised of four purchase periods of approximately six months in length. The offering periods are scheduled to start on the first trading day on or after June 11 and December 11 of each year. The first offering period commenced on June 11, 2019 and is scheduled to end on the first trading day on or before June 10, 2021.

The ESPP provides eligible employees with an opportunity to purchase shares of the Company’s Class A common stock through payroll deductions of up to 15% of their eligible compensation. A participant may purchase a maximum of 2,500 shares of common stock during a purchase period. Amounts deducted and accumulated by the participant are used to purchase shares of common stock at the end of each six-month purchase period. The purchase price of the shares shall be 85% of the lower of the fair market value of the Class A common stock on (i) the first trading day of the applicable offering period and (ii) the last trading day of each purchase period in the related offering period. Participants may end their participation at any time during an offering period and will be paid their accrued contributions that have not yet been used to purchase shares of common stock. Participation ends automatically upon termination of employment.

Employee payroll contributions ultimately used to purchase shares are reclassified to stockholders’ equity on the purchase date. ESPP employee payroll contributions accrued at October 31, 2019 totaled $10.2 million and are included within accrued compensation in the condensed consolidated balance sheets. The Company recorded stock-based compensation of $4.0 million and $6.3 million during the three and nine months ended October 31, 2019 in connection with the ESPP.

The fair value of the share purchase rights granted under the ESPP during the nine months ended October 31, 2019 was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:


			Nine Months Ended October 31,
			2019

Expected term (in years)			0.5 - 2.0
Risk-free interest rate			1.9 - 2.2%
Expected stock price volatility			33.0 - 35.7%

The Company uses channel partners to complement direct sales and marketing efforts. The partners place an order with the Company after negotiating the order directly with an end customer. The partners negotiate pricing with the end customer and in some rare instances are responsible for certain support levels directly with the end customer. The Company’s contract is with the partner and payment to the Company is not contingent on the receipt of payment from the end customer. The Company recognizes the contractual amount charged to the partners as revenue ratably over the term of the arrangement once access to the Company’s solution has been provided to the end customer.

The Company also uses referral partners who refer customers in exchange for a referral fee. The Company negotiates pricing and contracts directly with the end customer. The Company recognizes revenue from the sales to the end customers, ratably over the term of the contract, once access to the Company’s solution has been provided to the end customer.

Contract Balances

Contract liabilities consist of deferred revenue and include payments received in advance of performance under the contract. Such amounts are recognized as revenue over the contractual period. For the three and nine months ended October 31, 2019, the Company recognized revenue of $103.3 million and $203.7 million, respectively, that were included in the corresponding contract liability balance at the beginning of the period.

The Company receives payments from customers based upon contractual billing schedules. Accounts receivable are recorded when the right to consideration becomes unconditional. Payment terms on invoiced amounts are typically 30 - 60 days. Contract assets include amounts related to the contractual right to consideration for both completed and partially completed performance obligations that may not have been invoiced.

Changes in deferred revenue for the three and nine months ended October 31, 2019 were as follows (in thousands):


	Carrying Amount
	Three Months Ended October 31, 2019		Nine Months Ended October 31, 2019
Beginning Balance	$	369,762	$	290,067
Additions to deferred revenue	202,996		486,876
Recognition of deferred revenue	(125,119)		(329,304)
Ending Balance	$	447,639	$	447,639

Remaining Performance Obligations

The Company’s subscription contracts with its customers have a typical term of one to three years and most subscription contracts are non-cancelable. Customers typically have the right to terminate their contracts for cause as a result of the Company’s failure to perform. As of October 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $577.2 million. The Company expects to recognize 71% of the remaining performance obligations in the 12 months following October 31, 2019, with the remainder to be recognized thereafter.

Costs to Obtain and Fulfill a Contract

The Company capitalizes sales commission and associated payroll taxes paid to internal sales personnel that are incremental to the acquisition of channel partner and direct customer contracts and would not have occurred absent the customer contract. These costs are recorded as deferred contract acquisition costs on the condensed consolidated balance sheet.

Sales commissions for renewal of a contract are not considered commensurate with the commissions paid for the acquisition of the initial contract or follow-on upsell given the substantive difference in commission rates in proportion to their respective contract values. Commissions, including referral fees paid to channel partners, paid upon the initial acquisition of a contract or subsequent upsell are amortized over an estimated period of benefit of four years while commissions paid for renewal contracts are amortized over the contractual term of the renewals. Sales commissions associated with professional service contracts are amortized ratably over an estimated period of benefit of six months and included in sales and marketing expense in the condensed consolidated statements of operations. In determining the period of benefit for commissions paid for the acquisition of the initial contract, the Company took into consideration the expected subscription term and expected renewals of customer contracts, the historical duration of relationships with customers, customer retention data, and the life of the developed technology. The Company periodically reviews the carrying amount of deferred contract acquisition costs to determine whether events or changes in circumstances have occurred that could impact the period of benefit of these deferred costs. The Company did not recognize any impairment losses of deferred contract acquisition costs during the three and nine months ended October 31, 2019.

The following table summarizes the activity of deferred contract acquisition costs:

Litigation

The Company is currently involved in proceedings before the Trademark Trial and Appeal Board at the U.S. Patent and Trademark Office (the “USPTO”) regarding its U.S. trademark registrations for “CrowdStrike Falcon” and its U.S. application to register its “Falcon OverWatch” trademark. On November 23, 2016, Fair Isaac Corporation (“FICO”) filed a Petition for Cancellation of the Company’s “CrowdStrike Falcon” trademark registrations and a Notice of Opposition against the Company’s “Falcon OverWatch” trademark application before the USPTO, Trademark Trial and Appeal Board (“TTAB”). On January 3, 2017, the Company filed answers to both the cancellation and opposition proceedings, and the proceedings thereafter were consolidated. On November 21, 2018, the Company filed a Petition for Partial Cancellation or Amendment of one of FICO’s “Falcon” trademark registrations, and on December 10, 2018, the parties filed a joint request to consolidate the proceedings and adjust the schedule. On January 16, 2019, FICO moved to dismiss the Company’s petition, and the TTAB thereafter suspended all proceedings pending its ruling on the motions. On July 2, 2019, the TTAB issued an order granting the request to consolidate the proceedings and granting the motion to dismiss with leave to file an amended petition by July 22, 2019. The Company filed its Amended Petition for Cancellation or Amendment on July 22, 2019. On August 12, 2019, FICO moved to dismiss the Company’s Amended Petition for Cancellation. On October 1, 2019, the TTAB issued an order confirming that all proceedings were suspended as of August 12, 2019, pending disposition of the motion to dismiss. The Company is vigorously defending the case, but given the early stage, although a loss may reasonably be possible, the Company is unable to predict the likelihood of success of Fair Isaac’s claims or estimate a loss or range of loss. As a result, no liability has been recorded as of October 31, 2019 or January 31, 2019.

In addition, from time to time the Company is a party to various litigation matters and subject to claims that arise in the ordinary course of business. In addition, third parties may from time to time assert claims against the Company in the form of letters and other communications. For any claims for which the Company believes a liability is both probable and reasonably estimable, the Company records a liability in the period for which it makes this determination. There is no pending or threatened legal proceeding to which the Company is a party that, in the Company’s opinion, is likely to have a material adverse effect on its condensed consolidated financial statements; however, the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse impact on the Company’s business because of defense and settlement costs, diversion of management resources, and other factors. In addition, the expense of litigation and the timing of this expense from period to period are difficult to estimate, subject to change and could adversely affect the Company’s results of operations.

Warranties and Indemnification

The Company’s cloud computing services are typically warranted to perform in a manner consistent with general industry standards that are reasonably applicable and materially in accordance with the Company’s online help documentation under normal use and circumstances.

The Company’s arrangements generally include certain provisions for indemnifying customers against liabilities if its products or services infringe a third party’s intellectual property rights. In addition, for its Falcon Complete module customers, the Company offers a limited warranty, subject to certain conditions, to cover certain costs incurred by the customer in case of a cybersecurity breach. The Company has entered into an insurance policy to cover its potential liability arising from this limited warranty arrangement. To date, the Company has not incurred any material costs because of such obligations and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements.

The Company has also agreed to indemnify its directors and executive officers for costs associated with any fees, expenses, judgments, fines and settlement amounts incurred by any of these persons in any action or proceeding to which any of those persons is, or is threatened to be, made a party by reason of the person’s service as a director or officer, including any action by the Company, arising out of that person’s services as the Company’s director or officer or that person’s services provided to any other company or enterprise at the Company’s request. The Company maintains director and officer insurance coverage that would generally enable the Company to recover a portion of any future amounts paid. The Company may also be subject to indemnification obligations by law with respect to the actions of its employees under certain circumstances and in certain jurisdictions. No liabilities have been accrued associated with this indemnification provision as of October 31, 2019 or January 31, 2019.

Strategic Investments

The Company has elected the measurement alternative for the non-marketable equity investments of the Falcon Fund. Under the measurement alternative, the equity investments are measured at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The non-marketable equity investments of the Falcon Fund will be valued using significant unobservable inputs or data in inactive markets which require judgment due to the absence of market prices and inherent lack of liquidity. As a result, there could be volatility in the Company’s consolidated statements of operations in future periods due to the valuation and timing of identical or similar investments of the same issuer.

Deferred Contract Acquisition Costs

Deferred Contract Acquisition CostsThe Company capitalizes contract acquisition costs that are incremental to the acquisition of customer contracts. Contract acquisition costs are accrued and capitalized upon execution of the sales contract by the customer. Sales commissions for renewal of a contract are not considered commensurate with the commissions paid for the acquisition of the initial contract or follow-on upsell given the substantive difference in commission rates in proportion to their respective contract values. Commissions, including referral fees paid to channel partners, paid upon the initial acquisition of a contract or subsequent upsell are amortized over an estimated period of benefit of four years while commissions paid for renewal contracts are amortized over the contractual term of the renewals. Sales commissions associated with professional service contract are amortized ratably over an estimated period of benefit of six months. The Company capitalized contract acquisition costs of $27.4 million, which is under ASC606, and $13.2 million, which is under ASC 605, during the three months ended October 31, 2019 and October 31, 2018, respectively, and $55.2 million, which is under ASC 606, and $27.5 million, which is under ASC 605, during the nine months ended October 31, 2019 and October 31, 2018, respectively. Contract acquisition cost amortization expense was $9.0 million, which is under ASC 606, and $7.3 million, which was under ASC 605, during the three months ended October 31, 2019 and October 31, 2018, respectively, and $24.1 million, which is under ASC 606, and $19.3 million, which was under ASC 605, during the nine months ended October 31, 2019 and October 31, 2018, respectively

The Company’s effective tax rates of (1.24)% and (1.28)% for the three months ended October 31, 2019 and October 31, 2018, respectively, and (1.48)% and (0.94)% for the nine months ended October 31, 2019 and October 31, 2018, respectively, differ from the U.S. statutory tax rate primarily due to valuation allowance recorded against domestic losses and the tax rate differences between the United States and foreign countries. The Company has a full valuation allowance on its U.S. federal and state deferred tax assets. As a result, consistent with the prior year, the Company is unable to record a tax benefit on these losses because of uncertainty of future profitability.
