Business and Summary of Significant Accounting Policies	Oct. 31, 2021
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Business and Summary of Significant Accounting Policies	Business and Summary of Significant Accounting Policies Description of the Business Zscaler, Inc. ("Zscaler," the "Company," "we," "us," or "our") is a cloud security company that developed a platform incorporating core security functionalities needed to enable fast and secure access to cloud resources based on identity, context and organization’s policies. Our solution is a purpose-built, multi-tenant, distributed cloud platform that secures user-to-app, app-to-app, and machine-to-machine communications over any network and any location. We deliver our solutions using a software-as-a-service ("SaaS") business model and sell subscriptions to customers to access our cloud platform, together with related support services. We were incorporated in Delaware in September 2007 and conduct business worldwide, with presence in North America, Europe and Asia. Our headquarters are in San Jose, California. Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and applicable regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting, and include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable required disclosures and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company's audited consolidated financial statements and related notes in its Annual Report on Form 10-K for the fiscal year ended July 31, 2021 (the "Fiscal 2021 Form 10-K"), as filed with the SEC on September 16, 2021. Interim Unaudited Condensed Consolidated Financial Statements The accompanying condensed consolidated balance sheet as of July 31, 2021 was derived from the audited consolidated financial statements as of that date. The accompanying interim condensed consolidated financial statements, including the condensed consolidated balance sheet as of October 31, 2021, the condensed consolidated statements of operations for the three months ended October 31, 2021 and 2020, the condensed consolidated statements of comprehensive loss for the three months ended October 31, 2021 and 2020, the condensed consolidated statements of stockholders’ equity for the three months ended October 31, 2021 and 2020 and the condensed consolidated statements of cash flows for the three months ended October 31, 2021 and 2020 are unaudited. The related financial data and the other financial information disclosed in the accompanying notes to these condensed consolidated financial statements are also unaudited. These interim unaudited condensed consolidated financial statements have been prepared on a basis consistent with our annual consolidated financial statements and, in our opinion, include all normal recurring adjustments necessary to state fairly our quarterly results. The results of operations for the three months ended October 31, 2021 are not necessarily indicative of the results to be expected for our fiscal year ending July 31, 2022 or for any other future fiscal year or interim period. Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of revenue recognition, deferred revenue, deferred contract acquisition costs, valuation of acquired intangible assets, period of benefit generated from our deferred contract acquisition costs, allowance for doubtful accounts, valuation of common stock options and stock-based awards, useful lives of property and equipment, useful lives of acquired intangible assets, recoverability of goodwill, valuation of deferred tax assets and liabilities, loss contingencies related to litigation, fair value and effective interest rate of convertible senior notes, valuation of non-marketable equity investments and the discount rate used for operating leases. Management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Actual results could differ significantly from these estimates, and such differences may be material to the condensed consolidated financial statements. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. We are not aware of any specific event or circumstances that would require an update to our estimates, judgments or assumptions or a revision to the carrying value of our assets or liabilities as of the date of issuance of these condensed consolidated financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained. Fiscal Year Our fiscal year ends on July 31. References to fiscal 2022, for example, refer to our fiscal year ending July 31, 2022. Significant Accounting Policies Our significant accounting policies are described in the Fiscal 2021 Form 10-K. There have been no significant changes to these policies that have had a material impact on the condensed consolidated financial statements and related notes for the three months ended October 31, 2021. Recently Adopted Accounting Pronouncements In October 2021, the Financial Accounting Standards Board ("FASB") issued ASU No. 2021-08, Business Combinations (Topic 805) on Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This standard requires contract assets and contract liabilities from contracts with customers that are acquired in a business combination to be recognized and measured as if the acquirer had originated the original contract. Previously, acquired contract assets and liabilities were measured at fair value. This standard is effective for us in the first quarter of fiscal 2024, though early adoption is permitted. We early adopted this standard in the first quarter of fiscal 2022 and it did not have a material impact to the condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This standard eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. This standard is effective for us in the first quarter of fiscal 2023, using the fully retrospective or modified retrospective method, though early adoption is permitted. We are currently evaluating the potential impact of this standard on the condensed consolidated financial statements.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Disaggregation of Revenue

Subscription and support revenue is recognized over time and accounted for approximately 97% of our revenue for the three months ended October 31, 2021 and 2020, respectively.

The following table summarizes the revenue by region based on the shipping address of customers who have contracted to use our cloud platform:


	Three Months Ended October 31,
	2021				2020
	Amount		% Revenue		Amount		% Revenue

	(in thousands, except per percentage data)
United States	$	113,413	49	%	$	70,159	49	%
Europe, Middle East and Africa	80,549		35	%	55,205		39	%
Asia Pacific	31,052		14	%	14,280		10	%
Other	5,503		2	%	2,934		2	%
Total	$	230,517	100	%	$	142,578	100	%

The following table summarizes the revenue from contracts by type of customer:


	Three Months Ended October 31,
	2021				2020
	Amount		% Revenue		Amount		% Revenue

	(in thousands, except per percentage data)
Channel partners	$	215,073	93	%	$	133,440	94	%
Direct customers	15,444		7	%	9,138		6	%
Total	$	230,517	100	%	$	142,578	100	%

Significant Customers

No single customer accounted for 10% or more of the total revenue in the periods presented. The following table summarizes the concentration of 10% or more of the total balance of accounts receivable, net:


	October 31, 2021	July 31, 2021

Channel partner A	14%	*

(*) Represents less than 10%.

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. Deferred revenue, including current and noncurrent balances as of October 31, 2021 and July 31, 2021 was $647.8 million and $630.6 million, respectively. In the three months ended October 31, 2021 and 2020, we recognized revenue of $206.4 million and $127.6 million, respectively, that was included in the corresponding contract liability balance at the beginning of these periods.

Remaining Performance Obligations

The typical subscription and support term is one to three years. Most of our subscription and support contracts are non-cancelable over the contractual term. However, customers typically have the right to terminate their contracts for cause, if we fail to perform. As of October 31, 2021, the aggregate amount of the transaction price allocated to remaining performance obligations was $1,705.7 million. We expect to recognize 50% of the transaction price over the next 12 months and 97% of the transaction price over the next three years, with the remainder recognized thereafter.

Costs to Obtain and Fulfill a Contract

We capitalize sales commission and associated payroll taxes paid to internal sales personnel that are incremental to the acquisition of channel partner and direct customer contracts. These costs are recorded as deferred contract acquisition costs in the condensed consolidated balance sheets.

The activity of the deferred contract acquisition costs consisted of the following:


	Three Months Ended October 31,
	2021		2020

	(in thousands)
Beginning balance	$	207,030	$	109,915
Capitalization of contract acquisition costs	23,985		18,042
Amortization of deferred contract acquisition costs	(14,912)		(8,678)
Ending balance	$	216,103	$	119,279

The outstanding balance of the deferred contract acquisition costs consisted of the following:


	October 31, 2021		July 31, 2021

	(in thousands)
Deferred contract acquisition costs, current	$	62,067	$	57,373
Deferred contract acquisition costs, noncurrent	154,036		149,657
Total	$	216,103	$	207,030

Sales commissions accrued but not paid as of October 31, 2021 and July 31, 2021, totaled $16.3 million and $46.7 million, respectively, which are included within accrued compensation in the condensed consolidated balance sheets.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer.

We review the individual securities that have unrealized losses in our short-term investment portfolio on a regular basis. We evaluate, among others, whether we have the intention to sell any of these investments and whether it is not more likely than not that we will be required to sell any of them before recovery of the amortized cost basis. Neither of these criteria were met in any period presented. We additionally evaluate whether the decline in fair value of the corporate debt securities below the amortized cost basis is related to credit losses or other factors. Based on this evaluation, we determined that unrealized losses of the above securities were primarily attributable to changes in interest rates and non credit-related factors. Accordingly, we determined that an allowance for credit losses was unnecessary for our short-term investments as of October 31, 2021 and July 31, 2021.

We recorded $3.0 million and $3.9 million of accrued interest receivable within prepaid expenses and other current assets in the condensed consolidated balance sheets as of October 31, 2021 and July 31, 2021, respectively.

Strategic Investments

The carrying amount of our strategic investments, which consist of non-marketable investments, was $5.1 million as of October 31, 2021 and July 31, 2021, which are included within other noncurrent assets in the condensed consolidated balance sheets. There were no material events or circumstances impacting the carrying amount of our strategic investments during the periods presented.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

We measure our financial assets and liabilities at fair value at each reporting period using a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. A financial instrument’s classification within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

Our money market funds are classified within Level I due to the highly liquid nature of these assets and have quoted prices in active markets. Certain of our investments in available-for-sale securities (i.e., U.S. treasury securities, U.S. government agency securities and corporate debt securities), as well as our assets and liabilities arising from our foreign currency forward contracts, are classified within Level II. The fair value of our Level II financial assets and liabilities is determined by using inputs based on non-binding market consensus prices that are primarily corroborated by observable market data or quoted market prices for similar instruments, for substantially the full term of the financial assets and liabilities.

Assets and liabilities that are measured at fair value on a recurring basis consisted of the following as of October 31, 2021:


			Level I		Level II		Level III

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments	Derivative Instruments We implemented a foreign currency risk management program during the three months ended January 31, 2021. As a global business, we are exposed to foreign currency exchange rate risk. Substantially all of our revenue is transacted in U.S. dollars; however, a portion of our cost of revenues and operating expenditures are incurred outside of the United States and are denominated in foreign currencies, making them subject to fluctuations in foreign currency exchange rates. In order to mitigate the impact of foreign currency fluctuations on our future cash flows and earnings, we enter into foreign currency forward contracts, which we designate as cash flow hedges. All cash flow hedges were considered effective during the three months ended October 31, 2021. During the three months ended October 31, 2021, we began to use foreign currency forward contracts to mitigate variability in gains and losses generated from the remeasurement of certain monetary assets and liabilities denominated in foreign currencies. The outstanding non-designated derivative instruments are carried at fair value with changes recorded in other income (expense), net in the condensed consolidated statement of operations in the same period as the changes in fair value from the remeasurement of the underlying assets and liabilities. Cash flows from such derivatives are classified as operating activities. These foreign exchange contracts typically have maturities of approximately one to four months. Changes in the fair value of these derivatives were not material for the three months ended October 31, 2021. As of October 31, 2021 and July 31, 2021, the total notional amount of our outstanding foreign currency forward contracts was $123.4 million and $118.9 million, respectively for designated and $47.7 million and $28.2 million, respectively for non-designated foreign currency forward contracts. The maximum length of time over which forecasted foreign currency denominated operating expenses are hedged is 18 months. Substantially all of the unrealized gains and losses related to our cash flow hedges are expected to be released into earnings over the next 12 months. Refer to Note 4, Fair Value Measurements, for the fair value of our derivative instruments as reported on the condensed consolidated balance sheet as of October 31, 2021 and July 31, 2021. During the three months ended October 31, 2021, the unrealized gains and losses related to our cash flow hedges that were recognized in accumulated other comprehensive income (loss) ("AOCI") and the gains and losses reclassified into the condensed consolidated statement of operations were not material. During the three months ended October 31, 2021, changes in the fair value of our non-designated derivative instruments recorded in other income (expense), net within the condensed consolidated statements of operations were not material. Our derivative contracts expose us to credit risk to the extent that the counterparties may be unable to meet the terms of the underlying contracts. We mitigate this credit risk by transacting with major financial institutions with high credit ratings and standards. We periodically assess the creditworthiness of our counterparties to ensure they continue to meet our credit quality requirements. We also enter into master netting arrangements, which permit net settlement of transactions with the same counterparty. The potential impact of these rights of set-off associated with our derivative instruments was not material as of October 31, 2021 and July 31, 2021. We are not required to pledge, and are not entitled to receive, cash collateral related to these derivative instruments. We do not enter into derivative contracts for trading or speculative purposes.

Convertible Senior Notes

3 Months Ended

Oct. 31, 2021

Debt Disclosure [Abstract]

Convertible Senior Notes

On June 25, 2020, we issued $1,150.0 million in aggregate principal amount of 0.125% Convertible Senior Notes due 2025 (the “Notes”), including the exercise in full by the initial purchasers of the Notes of their option to purchase an additional $150.0 million principal amount of the Notes. The Notes are unsecured obligations and bear interest at a rate of 0.125% per year and interest is payable semiannually in arrears on January 1 and July 1 of each year, beginning on January 1, 2021. The Notes mature on July 1, 2025, unless earlier converted, redeemed or repurchased. The total net proceeds from the offering, after deducting initial purchase discounts and other debt issuance costs, was $1,130.5 million. Refer to Note 9, Convertible Senior Notes, in the Notes to Consolidated Financial Statements included in our Fiscal 2021 Form 10-K for further information on the Notes.

During the three months ended October 31, 2021, the conditional conversion feature of the Notes was triggered as the last reported sale price of our common stock was greater than or equal to 130% of the conversion price of the Notes for at least 20 trading days during the period of 30 consecutive trading days ending on October 29, 2021 (the last trading day of the fiscal quarter). Accordingly, the Notes are currently convertible, in whole or in part, at the option of the holders from November 1, 2021 through January 31, 2022. Whether the Notes will be convertible following such period will depend on the continued satisfaction of this condition or another conversion condition in the future. Conversion notices received through October 31, 2021 have not been material.

The net carrying amount of the liability component of the Notes consisted of the following:


	October 31, 2021		July 31, 2021

	(in thousands)
Principal amount	$	1,150,000	$	1,150,000

Unamortized debt issuance costs	11,255		11,935
Net carrying amount	$	927,014	$	913,538

The following table sets forth total interest expense recognized related to the Notes:

Amortization of debt discount	12,796		12,049
Amortization of debt issuance costs	680		641
Total	$	13,835	$	13,049

The total fair value of the Notes was $2,449.5 million and $1,931.7 million as of October 31, 2021 and July 31, 2021, respectively. The fair value was determined based on the closing trading price per $1,000 of the Notes as of the last day of trading for the period. We consider the fair value of the Notes as of October 31, 2021 to be a Level II measurement as they are not actively traded. The fair value of the Notes is primarily affected by the trading price of our common stock and market interest rates.

In connection with the pricing of the Notes, we entered into capped call transactions with the option counterparties (the "Capped Calls"). The Capped Calls each have an initial strike price of $150.80 per share, subject to certain adjustments, which corresponds to the initial conversion price of the Notes. The Capped Calls have an initial cap price of $246.76 per share, subject to certain adjustments. The Capped Calls are generally expected to reduce potential dilution to our common stock upon any conversion of the Notes and/or offset any cash payments we are required to make in excess of the principal amount of the converted Notes, as the case may be, with such reduction and/or offset subject to a cap. During the three months ended October 31, 2021 and 2020, we have not exercised any Capped Call options. Refer to Note 9, Convertible Senior Notes, in the Notes to Consolidated Financial Statements included in our Fiscal 2021 Form 10-K for further information on the Capped Calls.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Non-cancelable Purchase Obligations In the normal course of business, we enter into non-cancelable purchase commitments with various third parties to purchase products and services such as technology equipment, subscription-based cloud service arrangements, corporate and marketing events and consulting services. During the three months ended October 31, 2021, there have been no material changes outside the ordinary course of business to our non-cancelable purchase commitments from those disclosed in our Fiscal 2021 Form 10-K. Legal Matters Litigation and Claims We are a party to various litigation matters from time to time and subject to claims that arise in the ordinary course of business, including patent, commercial, product liability, employment, class action, whistleblower and other litigation and claims, as well as governmental and other regulatory investigations and proceedings. In addition, third parties may from time to time assert claims against us in the form of letters and other communications. There is no pending or threatened legal proceeding to which we are a party that, in our opinion, is likely to have a material adverse effect on our future financial results or operations; however, the results of litigation and claims are inherently unpredictable. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors. 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 our results of operations.

Employee Stock Purchase Plan

In fiscal 2018, we adopted the Fiscal Year 2018 Employee Stock Purchase Plan (the "ESPP"). ESPP employee payroll contributions accrued as of October 31, 2021 and July 31, 2021 were $13.3 million and $5.2 million, respectively, and are included within accrued compensation in the condensed consolidated balance sheets. Payroll contributions accrued as of October 31, 2021 will be used to purchase shares at the end of the current ESPP purchase period ending on December 15, 2021. There were no shares issued under the ESPP during the periods presented.

Stock-based Compensation Expense

The components of stock-based compensation expense, net of amounts capitalized in the development of software for internal-use, recognized in the condensed consolidated statements of operations consisted of the following:


	Three Months Ended October 31,

Total	$	89,903	$	57,185

During the three months ended October 31, 2021 and 2020, we capitalized $2.5 million and $1.5 million, respectively, of stock-based compensation associated with the development of software for internal-use.

Income Taxes	3 Months Ended
Income Taxes	Oct. 31, 2021
Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items, if any, that arise during the period. Each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual effective tax rate changes, we make a cumulative adjustment in such period. Our quarterly tax provision, and estimate of our annual effective tax rate, is subject to variation due to several factors, including variability in pre-tax income (or loss), the mix of jurisdictions to which such income relates, changes in how we do business, and tax law developments. Our estimated annual effective tax rate for the year differs from the U.S. statutory rate of 21% as a result of our U.S. losses for which no benefit will be realized, as well as our foreign operations which are subject to tax rates that differ from those in the United States. We recorded a provision for income taxes of $2.5 million and $0.5 million for the three months ended October 31, 2021 and 2020, respectively. We are subject to income tax in the United States as well as other tax jurisdictions in which we conduct business. Earnings from our non-U.S. operations are subject to income taxes in the countries in which we operate. Our provision for income taxes consists primarily of both income and withholding taxes in the foreign jurisdictions in which we conduct business. The realization of deferred tax assets is dependent upon the generation of sufficient taxable income of the appropriate character in future periods. We assess our ability to realize the deferred tax assets on a quarterly basis and we establish a valuation allowance if it is more-likely-than-not that some portion of the deferred tax assets will not be realized. We weigh all available positive and negative evidence, including our earnings history and results of recent operations, scheduled reversals of deferred tax liabilities, projected future taxable income and tax planning strategies. Due to the weight of objectively verifiable negative evidence, including our history of losses in certain jurisdictions, we believe that it is more likely than not that our U.S. federal, state, and U.K. deferred tax assets will not be realized. Accordingly, we have maintained a valuation allowance on our U.S. federal, state and U.K. deferred tax assets.

- Definition

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Net Loss Per Share

Earnings Per Share [Abstract]

Net Loss Per Share

The following table sets forth the computation of basic and diluted net loss per share:


	Three Months Ended October 31,
	2021		2020

	(in thousands)
Net loss	$	(90,801)	$	(55,006)
Weighted-average shares used in computing net loss per share, basic and diluted	139,296		133,452
Net loss per share, basic and diluted	$	(0.65)	$	(0.41)

Since we have reported net losses for all periods presented, we have excluded all potentially dilutive securities from the calculation of the diluted net loss per share as their effect is antidilutive and accordingly, the basic and diluted net loss per share is the same for all periods presented.

The following table summarizes the potentially dilutive securities outstanding as of October 31, 2021 and 2020 that were excluded from the computation of diluted net loss per share as their effect would be antidilutive:


	October 31,
	2021	2020

	(in thousands)

Unvested RSUs and shares of common stock	7,085	8,161
Stock options	2,206	4,475
Unvested PSAs (1)	676	577
Share purchase rights under the ESPP	697	547
Convertible senior notes (2)	7,626	—
Total	18,290	13,760

(1) The number of unvested PSAs is estimated at 100% of the target number of shares granted and excludes unvested PSAs for which performance conditions have not been established as of October 31, 2021 and 2020, as they are not considered outstanding for accounting purposes. Refer to Note 10, Stock-Based Compensation, for further information.

(2) The shares underlying the conversion option in the Notes were not considered in the calculation of diluted net loss per share as the effect would have been antidilutive. Based on the initial conversion price, the entire outstanding principal amount of the Notes as of October 31, 2021 would have been convertible into approximately 7.6 million shares of our common stock, as reflected in the above table. As we expect to settle the principal amount of the Notes in cash, only the amount by which the conversion value exceeds the aggregate principal amount of the Notes (the "conversion spread") is considered in the diluted earnings per share computation under the treasury stock method. The conversion spread has a dilutive impact on diluted net income per share when the average market price of our common stock for a given reporting period exceeds the initial conversion price of $150.80 per share for the Notes. Conversion notices received through October 31, 2021 have not been material. In connection with the issuance of the Notes, we entered into Capped Calls, which will not be included in the computation of the number of diluted shares outstanding, as their effect would be antidilutive. The Capped Calls are expected to partially offset the potential dilution to our common stock upon any conversion of the Notes.

Business and Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Oct. 31, 2021
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 conformity with accounting principles generally accepted in the United States ("U.S. GAAP") and applicable regulations of the Securities and Exchange Commission ("SEC") regarding interim financial reporting, and include the accounts of the Company and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Certain information and note disclosures normally included in the financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the applicable required disclosures and regulations of the SEC. Therefore, these unaudited condensed consolidated financial statements and accompanying notes should be read in conjunction with the Company's audited consolidated financial statements and related notes in its Annual Report on Form 10-K for the fiscal year ended July 31, 2021 (the "Fiscal 2021 Form 10-K"), as filed with the SEC on September 16, 2021.
Use of Estimates	Use of Estimates The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates, judgments and assumptions that affect the amounts reported and disclosed in the financial statements and accompanying notes. Such estimates include, but are not limited to, the determination of revenue recognition, deferred revenue, deferred contract acquisition costs, valuation of acquired intangible assets, period of benefit generated from our deferred contract acquisition costs, allowance for doubtful accounts, valuation of common stock options and stock-based awards, useful lives of property and equipment, useful lives of acquired intangible assets, recoverability of goodwill, valuation of deferred tax assets and liabilities, loss contingencies related to litigation, fair value and effective interest rate of convertible senior notes, valuation of non-marketable equity investments and the discount rate used for operating leases. Management determines these estimates and assumptions based on historical experience and on various other assumptions that are believed to be reasonable. Actual results could differ significantly from these estimates, and such differences may be material to the condensed consolidated financial statements. Due to the COVID-19 pandemic, there is ongoing uncertainty and significant disruption in the global economy and financial markets. We are not aware of any specific event or circumstances that would require an update to our estimates, judgments or assumptions or a revision to the carrying value of our assets or liabilities as of the date of issuance of these condensed consolidated financial statements. These estimates, judgments and assumptions may change in the future, as new events occur or additional information is obtained.
Fiscal Year	Fiscal Year Our fiscal year ends on July 31. References to fiscal 2022, for example, refer to our fiscal year ending July 31, 2022.
Recently Adopted Accounting Pronouncements; Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In October 2021, the Financial Accounting Standards Board ("FASB") issued ASU No. 2021-08, Business Combinations (Topic 805) on Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This standard requires contract assets and contract liabilities from contracts with customers that are acquired in a business combination to be recognized and measured as if the acquirer had originated the original contract. Previously, acquired contract assets and liabilities were measured at fair value. This standard is effective for us in the first quarter of fiscal 2024, though early adoption is permitted. We early adopted this standard in the first quarter of fiscal 2022 and it did not have a material impact to the condensed consolidated financial statements. Recently Issued Accounting Pronouncements Not Yet Adopted In June 2020, the FASB issued ASU No. 2020-06, Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40). This standard eliminates the beneficial conversion and cash conversion accounting models for convertible instruments. It also amends the accounting for certain contracts in an entity’s own equity that are currently accounted for as derivatives because of specific settlement provisions. In addition, the new guidance modifies how particular convertible instruments and certain contracts that may be settled in cash or shares impact the diluted earnings per share computation. This standard is effective for us in the first quarter of fiscal 2023, using the fully retrospective or modified retrospective method, though early adoption is permitted. We are currently evaluating the potential impact of this standard on the condensed consolidated financial statements.
