Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Business and Significant Accounting Policies	Summary of Business and Significant Accounting Policies Description of Business Zoom Video Communications, Inc. and its subsidiaries (together, “Zoom,” the “Company,” “we,” “us,” or “our”) provide a video-first, unified communications platform. Our platform combines video, audio, phone, screen sharing, and chat functionalities. We were incorporated in the state of Delaware in April 2011 and are headquartered in San Jose, California. Fiscal Year Our fiscal year ends on January 31. References to fiscal year 2021, for example, refer to the fiscal year ending January 31, 2021. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting, and include the accounts of Zoom Video Communications, Inc., its subsidiaries, and a variable interest entity (“VIE”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation. The condensed consolidated balance sheet as of January 31, 2020 included herein was derived from the audited financial statements as of that date, but does not include all disclosures, including certain notes required by GAAP on an annual reporting basis. The unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the balance sheets, statements of operations, statements of comprehensive income, statements of convertible preferred stock and stockholders’ equity (deficit), and statements of cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year or any future period. The unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended January 31, 2020, filed with the SEC on March 20, 2020. Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant items subject to such estimates and assumptions include, but are not limited to, the estimated expected benefit period for deferred contract acquisition costs, the allowance for credit losses, the useful lives of long-lived assets, the incremental borrowing rate for operating leases, the value of common stock and other assumptions used to measure stock-based compensation expense, sales and other tax liabilities, the fair value of the convertible promissory note, and the valuation of deferred income tax assets and uncertain tax positions. Actual results could differ from those estimates. The novel coronavirus (“COVID-19”) pandemic has created, and may continue to create, significant uncertainty in macroeconomic conditions, and the extent of its impact on our operational and financial performance will depend on certain developments, including the duration and spread of the outbreak and the impact on our customers and our sales cycles. During the three months ended April 30, 2020, many of our estimates and assumptions required increased judgment and carried a higher degree of variability and volatility. As events continue to evolve and additional information becomes available, our estimates may change materially in future periods. Summary of Significant Accounting Policies Our significant accounting policies are discussed in Note 1. “Summary of Business and Significant Accounting Policies” in the notes to consolidated financial statements included in our Annual Report on Form 10-K for the year ended January 31, 2020, filed with the SEC on March 20, 2020. There have been no significant changes to these policies during the three months ended April 30, 2020, except as noted below. Restricted Cash Restricted cash consisted of certificates of deposit collateralizing our operating leases, corporate credit cards, and cash from proceeds on international employees’ sales of our common stock, and is included in prepaid expenses and other current assets and other assets, noncurrent in the condensed consolidated balance sheets. As of April 30, 2020 and January 31, 2020, we had $267.1 million and $48.5 million, respectively, of cash from proceeds on international employees’ sales of our common stock. The amount is held in our bank account until it is remitted to the employees and the tax authorities. Due to the restrictions on the use of the funds in the bank account, we have classified the amount as restricted cash included in prepaid expenses and other current assets, and a corresponding amount included in accrued expenses and other current liabilities in the condensed consolidated balance sheets. Allowance for Credit Losses We are exposed to credit losses primarily through our accounts receivable and investments in available-for-sale debt securities. See Note 3 for additional information related to our available-for-sale debt securities. Accounts receivable, net Accounts receivable are recorded for invoiced amounts and amounts for which revenue has been recognized, but not invoiced, net of allowances. Our short-term accounts receivable consist of the following: April 30, 2020 (in thousands) Accounts receivable, gross $ 269,502 Less: allowance for credit losses (8,300) Less: allowance for returns (3,690) Accounts receivable, net $ 257,512 We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable, and changes in such are classified as general and administrative expense in the condensed consolidated statements of operations. The allowance for credit losses is based on management’s estimate for expected credit losses for outstanding accounts receivable. We determine expected credit losses based on historical write-off experience, an analysis of the aging of outstanding receivables, customer payment patterns, the establishment of specific reserves for customers in an adverse financial condition, and adjusted based upon our expectations of changes in macro-economic conditions that may impact the collectability of outstanding receivables, including noncurrent accounts receivable. We also consider current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. We reassess the adequacy of the allowance for credit losses each reporting period. For the three months ended April 30, 2020, our assessment considered business and market disruptions caused by COVID-19 and estimates of credit and collectibility trends. The continued volatility in market conditions and evolving shifts in credit trends are difficult to predict, causing variability and volatility that may have a material impact on our allowance for credit losses in future periods. Below is a rollforward of our allowance for credit losses for the three months ended April 30, 2020: (in thousands) Balance as of January 31, 2020 $ 5,150 Provision for credit losses 3,771 Write-offs (621) Balance as of April 30, 2020 $ 8,300 Available-for-sale Investments Available-for-sale investments consist primarily of high-grade commercial paper, agency bonds, corporate bonds, corporate and other debt securities, U.S. government agency securities, and treasury bills. We classify our marketable securities as available-for-sale at the time of purchase and reevaluate such classification at each balance sheet date. We may sell these securities at any time for use in current operations even if they have not yet reached maturity. As a result, we classify our securities, including those with maturities beyond 12 months, as current assets in the condensed consolidated balance sheets. We carry these securities at fair value and record unrealized gains and losses in accumulated other comprehensive income, which is reflected as a component of stockholders’ equity. We evaluate our securities with unrealized loss positions as to whether the declines in fair value were due to credit losses, and record the portion of impairment relating to the credit losses through allowance for credit losses limited to the amount that fair value was less than the amortized cost basis. Realized gains and losses from the sale of marketable securities are determined based on the specific identification method. Realized gains and losses are reported in interest income and other, net in the condensed consolidated statements of operations. Cloud Computing Arrangement Implementation Costs We capitalize certain implementation costs incurred in a cloud computing arrangement during the application development stage. Costs incurred in the preliminary stages of development are analogous to research and development activities and are expensed as incurred. The preliminary stage includes activities such as formulation and evaluation of alternatives, determination of existence of needed technology, and final selection of alternatives. Once the application development stage is reached, internal and external costs are capitalized until the hosted software is ready for its intended use. Capitalized implementation costs are recorded as deferred costs, and are included in prepaid expenses and other current assets and other assets, noncurrent in the condensed consolidated balance sheets. Maintenance, minor upgrades, and training costs are expensed as incurred. Capitalized implementation costs are amortized over the term of the hosting arrangement on a straight-line basis, and are recorded under operating expenses in the same line item in the condensed consolidated statements of operations as the expense for fees for the associated hosting arrangement. The capitalized implementation costs were not material during the three months ended April 30, 2020. Equity Investment In the third quarter of fiscal year 2020, we made a $3.0 million strategic investment in a private company in the business of designing and developing video communications hardware. In the first quarter of fiscal year 2021, we made an additional $8.0 million strategic investment in this company. We do not have a controlling financial interest in the investee nor the ability to exercise significant influence over the operating and financial policies of the investee. The investment is included within other assets, noncurrent in the condensed consolidated balance sheets. Dividend income, unrealized and realized holding gains or losses, and impairment charges would be reported in interest income and other, net in the condensed consolidated statements of operations. The maximum loss we could incur for this investment is its carrying value. We have elected to measure this investment, which does not have a readily determinable fair value, at its cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer (i.e., using the measurement alternative). At each reporting period, we perform a qualitative assessment considering impairment indicators to evaluate whether the investment is impaired. If this qualitative assessment indicates that the investment is impaired and the fair value of the investment is less than its carrying amount, the investment would be written down to its fair value. In connection with the additional investment and the indicated change in the observable price of the underlying shares of the investee as a result of orderly transactions, we have recognized a remeasurement gain of $2.5 million on the initial investment. As of April 30, 2020, the carrying amount of this investment was $13.5 million. Convertible Promissory Note In the first quarter of fiscal year 2021, we invested $5.0 million in a five The Convertible Note is included in other assets, noncurrent in the condensed consolidated balance sheets. Interest accrues on the unpaid principal balance on a quarterly basis, and is recognized in interest income and other, net in the condensed consolidated statements of operations. Interest income related to the Convertible Note was immaterial for the three months ended April 30, 2020. We have elected to measure the Convertible Note at fair value (i.e., using the fair value option). Under the fair value option, bifurcation of an embedded derivative is not necessary, and all related gains and losses on the host contract and derivative due to change in the fair value will be reflected in interest income and other, net in the condensed consolidated statements of operations. As of April 30, 2020, the fair value of the Convertible Note investment was measured at $5.0 million. Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which was subsequently amended by ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses , in November 2018. Subsequently, the FASB issued ASU No. 2019-04, ASU No. 2019-05, ASU No. 2019-10, and ASU No. 2019-11 to provide additional guidance on the credit losses standard. ASU No. 2016-13 and the related updates replace the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance is effective for the annual periods in fiscal years beginning after December 15, 2019, and interim periods therein. We adopted the standard as of February 1, 2020, using the modified retrospective method of applying the new standard at the adoption date. Our adoption did not result in any cumulative effect adjustment on our condensed consolidated financial statements upon adoption as of February 1, 2020. 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 . The amendment 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 (and hosting arrangements that include an internal-use software license). The guidance is effective for the annual periods in fiscal years beginning after December 15, 2019, and interim periods therein. We adopted ASU No. 2018-15, prospectively, as of February 1, 2020, and our adoption did not have a material impact on the condensed consolidated financial statements.

Accounts receivable are recorded when we contractually have the right to consideration. In some arrangements, a right to consideration for our performance under the customer contract may occur before invoicing to the customer, resulting in an unbilled accounts receivable. The amount of unbilled accounts receivable included within accounts receivable, net of allowances in the condensed consolidated balance sheets was $19.6 million and $12.5 million as of April 30, 2020 and January 31, 2020, respectively. Contract liabilities consist of deferred revenue. Revenue is deferred when we have the right to invoice in advance of performance under a customer contract. The current portion of deferred revenue balances is recognized over the next 12 months. The amount of revenue recognized during the three months ended April 30, 2020 and 2019 that was included in deferred revenue at the beginning of each period was $98.0 million and $53.6 million, respectively. Remaining Performance Obligation The terms of our subscription agreements are monthly, annual, and multiyear, and we may bill for the full term in advance or on an annual or monthly basis, depending on the billing terms with customers. As of April 30, 2020, the aggregate amount of the transaction price allocated to our remaining performance obligations was $1.1 billion, which consists of both billed consideration in the amount of $551.8 million and unbilled consideration in the amount of $516.1 million that we expect to recognize as revenue. We expect to recognize 72% of our remaining performance obligations as revenue over the next 12 months and the remainder thereafter.

We evaluate, among other factors, whether we have the intention to sell any of these marketable securities and whether it is more likely than not that we will be required to sell any of them before recovery of the amortized cost basis. We have not recorded an allowance for credit losses, as we believe any such losses would be immaterial based on the high-grade credit rating for each of our marketable securities as of the end of each period. There were no material realized gains or losses from available-for-sale securities that were reclassified out of accumulated other comprehensive income for the three months ended April 30, 2020 and 2019.

We classify our commercial paper, agency bonds, corporate bonds, corporate and other debt securities, U.S. government agency securities, treasury bills, and certificates of deposit within Level 2 because they are valued using inputs other than quoted prices that are directly or indirectly observable in the market, including readily available pricing sources for the identical underlying security which may not be actively traded. We classify the Convertible Note as Level 3 due to the lack of relevant observable market data over fair value inputs, such as the probability weighting of the various scenarios that can impact settlement of the arrangement. As of April 30, 2020 and January 31, 2020, the carrying amount of the equity investment was $13.5 million and $3.0 million, respectively. We classify the equity investment as Level 3 within the fair value hierarchy only if an impairment or

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancelable Purchase Obligations As of April 30, 2020, we had additional outstanding non-cancelable purchase obligations with a term of 12 months or longer of $18.0 million, related to third-party cloud hosting to meet the significant increase in usage of our services. Operating Leases Not Yet Commenced As of April 30, 2020, we had additional operating leases for office space that have not yet commenced with undiscounted future lease payments of $8.9 million. These operating leases will commence in the fourth quarter of fiscal year 2021. License Agreement In May 2020, we entered into a license agreement with MPEG LA, LLC (“MPEGLA”) to obtain the rights for future use of licensed intellectual property in exchange for periodic royalty payments. In connection with the license agreement, we agreed to make a royalty payment of $9.8 million to use the technology until December 31, 2020. In addition, we also agreed to make a one-time payment of $9.8 million for past use, which was recorded in general and administrative expenses in our condensed consolidated statements of operations for the three months ended April 30, 2020. Legal Proceedings Beginning on March 30, 2020, multiple putative class actions were filed against us in various U.S. federal district courts and in one state court relating to our alleged privacy and security practices, including alleged data sharing with third parties (the “U.S. Privacy Class Actions”). The plaintiffs claim violations of a variety of state consumer protection and privacy laws, and also assert state constitutional and common law claims, such as negligence and unjust enrichment. They seek to certify both nationwide and state-specific classes of individuals using our services in certain time periods. The plaintiffs seek various forms of injunctive and monetary relief, including restitution, statutory and actual damages, and attorneys’ fees. The federal cases have been transferred to the Northern District of California and have nearly completed the process of being related there for consolidated litigation, with our consent. On April 7, 2020 and April 8, 2020, securities class action complaints were filed against us and two of our officers in the United States District Court for the Northern District of California. The plaintiffs are purported stockholders of the company. The complaints allege, among other things, that we violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 by making false and misleading statements and omissions of material fact about our data privacy and security measures. The complaints seek unspecified damages, interest, fees, and costs. We believe these lawsuits are without merit, and we are vigorously defending ourselves against them. Given the uncertainty of litigation, the preliminary stage of the cases, and the legal standards that must be met for, among other things, class certification and success on the merits, we cannot estimate the reasonably possible loss or range of loss that may result from these actions.

Stockholders' Equity Note [Abstract]
Stockholders’ Equity and Equity Incentive Plan	Stockholders’ Equity and Equity Incentive Plan Common Stock In connection with our initial public offering (“IPO”) in April 2019, our amended and restated certificate of incorporation became effective, which authorized the issuance of 2,000,000,000 shares of Class A common stock, $0.001 par value per share and 300,000,000 shares of Class B common stock, $0.001 par value per share. Class A and Class B common stock are referred to as common stock throughout the notes to the condensed consolidated financial statements, unless otherwise noted. Equity Incentive Plans In 2011, we adopted the 2011 Global Share Plan (“2011 Plan”), under which officers, employees, and consultants may be granted various forms of equity incentive compensation at the discretion of the board of directors, including stock options and restricted stock awards. In connection with the IPO, the shares of Class B common stock remaining available for issuance under the 2011 Plan became available for issuance for a corresponding number of shares of our Class A common stock under the 2019 Equity Incentive Plan (“2019 Plan”). In April 2019, we adopted the 2019 Plan, which is a successor to and continuation of our 2011 Plan and which became effective in connection with our IPO. Our 2019 Plan provides for the grant of stock options, stock appreciation rights, restricted stock awards, restricted stock unit (“RSU”) awards, performance awards, and other forms of awards. The maximum number of shares of our Class A common stock that may be issued under our 2019 Plan will not exceed 58,300,889 shares of our Class A common stock, which is the sum of (1) 34,000,000 new shares, plus (2) an additional number of shares not to exceed 24,300,889, consisting of (A) shares that remain available for the issuance of awards under our 2011 Plan as of immediately prior to the time our 2019 Plan became effective and (B) shares of Class B common stock subject to outstanding stock options or other stock awards granted under our 2011 Plan that, on or after the 2019 Plan becomes effective, terminate, or expire prior to exercise or settlement; are not issued because the award is settled in cash; are forfeited because of the failure to vest; or are reacquired or withheld (or not issued) to satisfy a tax withholding obligation or the purchase or exercise price, if any, as such shares become available from time to time. In addition, the number of shares of our Class A common stock reserved for issuance under our 2019 Plan will automatically increase on February 1 of each calendar year, starting on February 1, 2020 through February 1, 2029, in an amount equal to (i) 5% of the total number of shares of our common stock (both Class A and Class B) outstanding on January 31 of the fiscal year before the date of each automatic increase, or (ii) a lesser number of shares determined by our board of directors prior to the applicable February 1. Stock Options A summary of stock option activity under our equity incentive plan and related information is as follows: Stock Options Outstanding Weighted- Weighted- Aggregate (in thousands, except share, life, and per share data) Balance as of January 31, 2020 16,833,009 $ 5.73 7.6 $ 1,191,881 Granted — $ — Exercised (3,232,991) $ 2.97 Canceled/forfeited/expired (52,093) $ 4.63 Balance as of April 30, 2020 13,547,925 $ 6.39 7.6 $ 1,744,720 Vested and exercisable as of April 30, 2020 5,449,596 $ 2.70 7.0 $ 721,922 As of April 30, 2020, unrecognized stock-based compensation expense related to outstanding unvested stock options was $69.0 million, which is expected to be recognized over a weighted-average period of 2.6 years. Restricted Stock Units A summary of RSU activity under our equity incentive plan and related information is as follows: RSUs Unvested Weighted- Unvested as of January 31, 2020 1,964,668 $ 79.11 Granted 419,354 $ 119.62 Vested (37,518) $ 80.36 Canceled/forfeited (33,653) $ 80.78 Unvested as of April 30, 2020 2,312,851 $ 86.42 As of April 30, 2020, unrecognized stock-based compensation expense related to outstanding unvested RSUs was $179.4 million, which is expected to be recognized over a weighted-average period of 3.5 years. 2019 Employee Stock Purchase Plan In April 2019, we adopted the 2019 Employee Stock Purchase Plan (“ESPP”), which became effective in connection with the IPO. A total of 9,000,000 shares of our Class A common stock were initially reserved for issuance under the ESPP. The number of shares of our Class A common stock reserved for issuance will automatically increase on February 1 of each calendar year, beginning on February 1, 2020 through February 1, 2029, by the lesser of (1) 1% of the total number of shares of our common stock (both Class A and Class B) outstanding on the last day of the fiscal year before the date of the automatic increase and (2) 7,500,000 shares; provided that before the date of any such increase, our board of directors may determine that such increase will be less than the amount set forth in clauses (1) and (2). Under our current ESPP, Class A common stock will be purchased for the accounts of employees participating in the ESPP at a price per share equal to the lesser of (1) 85% of the fair market value of a share of our Class A common stock on the first date of an offering or (2) 85% of the fair market value of a share of our Class A common stock on the date of purchase. No employee may purchase shares under the ESPP at a rate in excess of $25,000 worth of our Class A common stock based on the fair market value per share of our Class A common stock at the beginning of an offering for each calendar year such purchase right is outstanding or 3,000 shares. The 2019 ESPP provides for, at maximum, 27 months offering periods with four offering dates, generally in June and December of each year. The first offering period began on April 18, 2019. As of April 30, 2020, 490,268 shares of our Class A common stock have been purchased under the ESPP. As of April 30, 2020, unrecognized stock-based compensation expense related to the ESPP was $48.2 million, which is expected to be recognized over a weighted-average period of 1.1 years. Early Exercise of Common Stock Options Our board of directors authorized certain stock option holders to exercise unvested options to purchase shares of common stock. Shares received from such early exercises are subject to repurchase in the event of the optionee’s termination of service, at the original issuance price, until the options are fully vested. As of April 30, 2020 and January 31, 2020, 408,662 and 466,819 shares of Class B common stock, respectively, were subject to repurchase at a weighted-average price of $2.60 and $2.58 per share, respectively. The cash proceeds received for unvested shares of common stock recorded within accrued expenses and other current liabilities in the condensed consolidated balance sheets were $1.1 million and $1.2 million as of April 30, 2020 and January 31, 2020, respectively. Shares Reserved for Charitable Donations During fiscal year 2020, our board of directors approved the issuance of 500,000 shares of Class A common stock for the sole purpose of being transferred to a nonprofit organization to be formed or identified by us at a future time. As of April 30, 2020, 6,844 shares of Class A common stock have been transferred to a nonprofit organization. We recorded a non-cash charge of $1.0 million for the fair value of the donated shares, which was recorded in general and administrative expense in the condensed consolidated statements of operations for the three months ended April 30, 2020. Stock-Based Compensation The stock-based compensation expense by line item in the accompanying condensed consolidated statements of operations is summarized as follows: Three Months Ended April 30, 2020 2019 (in thousands) Cost of revenue $ 3,249 $ 830 Research and development 5,224 1,164 Sales and marketing 17,123 2,627 General and administrative 3,181 2,041 Total stock-based compensation expense $ 28,777 $ 6,662

The provision for income taxes for the three months ended April 30, 2020 consisted primarily of foreign income taxes and state taxes. For the three months ended April 30, 2020 and 2019, the provision for income taxes differed from the U.S. federal statutory rate primarily due to stock-based compensation and the full valuation allowance on the U.S. and the U.K. deferred tax assets. The realization of tax benefits of net deferred tax assets is dependent upon future levels of taxable income, of an appropriate character, in the periods the items are expected to be deductible or taxable. Based on the available objective evidence during the three months ended April 30, 2020, we believe it is more likely than not that the tax benefits of the U.S. and the U.K. losses incurred may not be realized. Accordingly, we recorded a full valuation allowance against the tax benefits of the U.S. and the U.K. losses incurred. We intend to maintain the full valuation allowance on the U.S. and the U.K. net deferred tax assets until sufficient positive evidence exists to support a reversal of, or decrease in, the valuation allowance.

Summary of Business and Signi_2

Summary of Business and Significant Accounting Policies (Policies)	3 Months Ended
	Apr. 30, 2020
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and applicable regulations of the Securities and Exchange Commission (“SEC”) regarding interim financial reporting, and include the accounts of Zoom Video Communications, Inc., its subsidiaries, and a variable interest entity (“VIE”) for which we are the primary beneficiary. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Significant items subject to such estimates and assumptions include, but are not limited to, the estimated expected benefit period for deferred contract acquisition costs, the allowance for credit losses, the useful lives of long-lived assets, the incremental borrowing rate for operating leases, the value of common stock and other assumptions used to measure stock-based compensation expense, sales and other tax liabilities, the fair value of the convertible promissory note, and the valuation of deferred income tax assets and uncertain tax positions. Actual results could differ from those estimates.
Restricted Cash	Restricted Cash Restricted cash consisted of certificates of deposit collateralizing our operating leases, corporate credit cards, and cash from proceeds on international employees’ sales of our common stock, and is included in prepaid expenses and other current assets and other assets, noncurrent in the condensed consolidated balance sheets.
Allowance for Credit Losses	Allowance for Credit LossesWe are exposed to credit losses primarily through our accounts receivable and investments in available-for-sale debt securities. We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable, and changes in such are classified as general and administrative expense in the condensed consolidated statements of operations. The allowance for credit losses is based on management’s estimate for expected credit losses for outstanding accounts receivable. We determine expected credit losses based on historical write-off experience, an analysis of the aging of outstanding receivables, customer payment patterns, the establishment of specific reserves for customers in an adverse financial condition, and adjusted based upon our expectations of changes in macro-economic conditions that may impact the collectability of outstanding receivables, including noncurrent accounts receivable. We also consider current market conditions and reasonable and supportable forecasts of future economic conditions to inform adjustments to historical loss data. We reassess the adequacy of the allowance for credit losses each reporting period.For the three months ended April 30, 2020, our assessment considered business and market disruptions caused by COVID-19 and estimates of credit and collectibility trends. The continued volatility in market conditions and evolving shifts in credit trends are difficult to predict, causing variability and volatility that may have a material impact on our allowance for credit losses in future periods.
Available for Sale Investments	Available-for-sale Investments Available-for-sale investments consist primarily of high-grade commercial paper, agency bonds, corporate bonds, corporate and other debt securities, U.S. government agency securities, and treasury bills. We classify our marketable securities as available-for-sale at the time of purchase and reevaluate such classification at each balance sheet date. We may sell these securities at any time for use in current operations even if they have not yet reached maturity. As a result, we classify our securities, including those with maturities beyond 12 months, as current assets in the condensed consolidated balance sheets. We carry these securities at fair value and record unrealized gains and losses in accumulated other comprehensive income, which is reflected as a component of stockholders’ equity. We evaluate our securities with unrealized loss positions as to whether the declines in fair value were due to credit losses, and record the portion of impairment relating to the credit losses
Cloud Computing Arrangement Implementation Costs	Cloud Computing Arrangement Implementation Costs We capitalize certain implementation costs incurred in a cloud computing arrangement during the application development stage. Costs incurred in the preliminary stages of development are analogous to research and development activities and are expensed as incurred. The preliminary stage includes activities such as formulation and evaluation of alternatives, determination of existence of needed technology, and final selection of alternatives. Once the application development stage is reached, internal and external costs are capitalized until the hosted software is ready for its intended use. Capitalized implementation costs are recorded as deferred costs, and are included in prepaid expenses and other current assets and other assets, noncurrent in the condensed consolidated balance sheets. Maintenance, minor upgrades, and training costs are expensed as incurred. Capitalized implementation costs are amortized over the term of the hosting arrangement on a straight-line basis, and are recorded under operating expenses in the same line item in the condensed consolidated statements of operations as the expense for fees for the associated hosting arrangement. The capitalized implementation costs were not material during the three months ended April 30, 2020.
Convertible Promissory Note	Convertible Promissory Note In the first quarter of fiscal year 2021, we invested $5.0 million in a five The Convertible Note is included in other assets, noncurrent in the condensed consolidated balance sheets. Interest accrues on the unpaid principal balance on a quarterly basis, and is recognized in interest income and other, net in the condensed consolidated statements of operations. Interest income related to the Convertible Note was immaterial for the three months ended April 30, 2020. We have elected to measure the Convertible Note at fair value (i.e., using the fair value option). Under the fair value option, bifurcation of an embedded derivative is not necessary, and all related gains and losses on the host contract and derivative due to change in the fair value will be reflected in interest income and other, net in the condensed consolidated statements of operations. As of April 30, 2020, the fair value of the Convertible Note investment was measured at $5.0 million.
Equity Investment	We do not have a controlling financial interest in the investee nor the ability to exercise significant influence over the operating and financial policies of the investee. The investment is included within other assets, noncurrent in the condensed consolidated balance sheets. Dividend income, unrealized and realized holding gains or losses, and impairment charges would be reported in interest income and other, net in the condensed consolidated statements of operations. The maximum loss we could incur for this investment is its carrying value. We have elected to measure this investment, which does not have a readily determinable fair value, at its cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer (i.e., using the measurement alternative). At each reporting period, we perform a qualitative assessment considering impairment indicators to evaluate whether the investment is impaired. If this qualitative assessment indicates that the investment is impaired and the fair value of the investment is less than its carrying amount, the investment would be written down to its fair value.
Recently Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments , which was subsequently amended by ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses , in November 2018. Subsequently, the FASB issued ASU No. 2019-04, ASU No. 2019-05, ASU No. 2019-10, and ASU No. 2019-11 to provide additional guidance on the credit losses standard. ASU No. 2016-13 and the related updates replace the existing incurred loss impairment model with an expected credit loss model and requires a financial asset measured at amortized cost to be presented at the net amount expected to be collected. The guidance is effective for the annual periods in fiscal years beginning after December 15, 2019, and interim periods therein. We adopted the standard as of February 1, 2020, using the modified retrospective method of applying the new standard at the adoption date. Our adoption did not result in any cumulative effect adjustment on our condensed consolidated financial statements upon adoption as of February 1, 2020. 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 . The amendment 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 (and hosting arrangements that include an internal-use software license). The guidance is effective for the annual periods in fiscal years beginning after December 15, 2019, and interim periods therein. We adopted ASU No. 2018-15, prospectively, as of February 1, 2020, and our adoption did not have a material impact on the condensed consolidated financial statements.
