Organization, Consolidation and Presentation of Financial Statements [Abstract]

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 users to safely utilize authorized applications and services based on an organization’s policies. Our solution is a purpose-built, multi-tenant, distributed cloud security platform that secures access for users and devices to applications and services, regardless of 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.

Reverse Stock Split

In March 2018, our board of directors approved an amendment to the Company's amended and restated certificate of incorporation effecting a 2-for-3 reverse stock split of the Company's issued and outstanding shares of common stock and convertible preferred stock. The reverse stock split was effected on March 1, 2018. All issued and outstanding share and per share amounts included in the accompanying condensed consolidated financial statements have been adjusted to reflect this reverse stock split for all periods presented.

Initial Public Offering

In March 2018, we completed our initial public offering ("IPO") of common stock, in which we sold 13,800,000 shares. The shares were sold at an IPO price of $16.00 per share for net proceeds of $205.3 million, after deducting underwriters' discounts and commissions of $15.5 million. In connection with the IPO, we incurred offering costs of $6.2 million which were recorded in stockholders’ equity as a reduction of the net proceeds received from the IPO. Immediately prior to the closing of the IPO, all our outstanding shares of convertible preferred stock were automatically converted into 72,500,750 shares of common stock on a one-to-one basis.

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 footnotes 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, 2018 (the "Fiscal 2018 Form 10-K"), as filed with the SEC on September 13, 2018.

Interim Unaudited Condensed Consolidated Financial Statements

The accompanying condensed balance sheet as of July 31, 2018 was derived from the audited financial statements as of that date. The accompanying interim condensed consolidated financial statements, including the consolidated balance sheets as of January 31, 2019, the consolidated statements of operations for the three and six months ended January 31, 2019 and 2018, the consolidated statements of comprehensive loss for the three and six months ended January 31, 2019 and 2018, the consolidated statements of cash flows for the six months ended January 31, 2019 and 2018, the consolidated statement of redeemable convertible preferred stock and stockholders’ equity (deficit) for the three and six months ended January 31, 2019 and 2018 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 and six months ended January 31, 2019 are not necessarily indicative of the results to be expected for the fiscal year ending July 31, 2019 or for any other future fiscal year or interim period.

JOBS Act Extended Transition Period

We are an emerging growth company ("EGC") as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). As an EGC, the JOBS Act allows us to take advantage of specified reduced reporting requirements that are otherwise generally applicable 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. We have irrevocably elected not to avail ourselves of the extended transition periods available under the JOBS Act for complying with new and revised accounting standards and, therefore, we are subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

As a result of our transition to large accelerated filer status as of July 31, 2019, we will cease to qualify as an emerging growth company and will no longer have the option to take advantage of the extended transition 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, the 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, loss contingencies related to litigation and valuation of deferred tax assets. 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.

Fiscal Year

Our fiscal year ends on July 31. References to fiscal 2019, for example, refer to our fiscal year ending July 31, 2019.

Significant Accounting Policies

Our significant accounting policies are discussed in the "Index to Consolidated Financial Statements, Note 1. Business and Summary of Significant Accounting Policies" in the Fiscal 2018 Form 10-K. There have been no significant changes to these policies that have had a material impact on our condensed consolidated financial statements and related notes for the three and six months ended January 31, 2019. The following describes the impact of certain policies.

Revenue Recognition

We adopted Accounting Standards Codification ("ASC") Topic 606, Revenue From Contracts With Customers ("ASC 606") on August 1, 2017, using the full retrospective transition method.

Disaggregation of Revenue

Subscription and support revenue is recognized over time and accounted for approximately 97% and 99% of our revenue for the three months ended January 31, 2019 and 2018, respectively, and approximately 98% of our revenue for the six months ended January 31, 2019 and 2018.

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 six months ended January 31, 2019 and 2018, we recognized revenue of $68.2 million and $58.6 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 January 31, 2019, the aggregate amount of the transaction price allocated to remaining performance obligations was $461.0 million. We expect to recognize 55% of the transaction price over the next 12 months and 98% of the transaction price over the next three years, with the remainder recognized thereafter.

Costs to Obtain and Fulfill a Contract

We capitalize sales commissions 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 following table summarizes the activity of the deferred contract acquisition costs:


	Three Months Ended January 31,						Six Months Ended January 31,
	2019		2018		2019		2018
	(in thousands)
Beginning balance	$	55,978	$	36,002	$	55,910	$	34,662

Total deferred contract acquisition costs	$	60,601	$	39,943	$	60,601	$	39,943

Sales commissions accrued but not paid as of January 31, 2019 and July 31, 2018, totaled $4.6 million and $10.0 million, respectively, which are included within accrued compensation in the condensed consolidated balance sheets.

Deferred Offering Costs

Deferred offering costs consisted of fees and expenses incurred in connection with our IPO, including legal, accounting, printing and other IPO-related costs. Total deferred offering costs of $6.2 million were reclassified to stockholders' equity (deficit) as a reduction of the net proceeds received from the IPO.

Recently Adopted Accounting Pronouncements

In January 2017, the Financial Accounting Standard Board ("FASB") issued Accounting Standard Update ("ASU") No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. The amendment was issued to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions of assets or businesses. This standard provides a screen test to determine when a set (inputs and processes that produce an output) is not a business. The screen requires that when 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 is not a business. We adopted this standard as of August 1, 2018, and it did not have a material impact to our consolidated financial statements.

In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which provides clarity in applying the guidance in Topic 718 around modifications of share-based payment awards. We adopted this standard as of August 1, 2018, and it did not have a material impact to our consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The new standard eliminates the diversity in practice related to the classification of certain cash receipts and payments for debt prepayment or extinguishment costs, the maturing of a zero-coupon bond, the settlement of contingent liabilities arising from a business combination, proceeds from insurance settlements, distributions from certain equity method investees and beneficial interests obtained in a financial asset securitization. We adopted this standard as of August 1, 2018 using the retrospective transition method, and it did not have a material impact to our consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that amounts generally described as restricted cash or restricted cash equivalents be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. We adopted this standard as of August 1, 2018 using the retrospective transition method and we have adjusted our prior period condensed consolidated statement of cash flows to conform to the current presentation.

In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for equity awards granted to nonemployees. For public business entities, it is effective for fiscal years beginning after December 15, 2018, and interim periods therein. Early adoption is permitted. We early adopted this standard as of August 1, 2018 using the prospective transition method, which resulted in a cumulative-effect adjustment of $0.3 million recognized within stockholders' equity, as a reduction of additional paid-in capital against accumulated deficit, on the adoption date.

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,” which 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. The new standard requires capitalized costs to be amortized on a straight-line basis generally over the term of the arrangement, and the financial statement presentation for these capitalized costs would be the same as that of the fees related to the hosting arrangements. For public business entities, this standard is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. We early adopted this standard as of August 1, 2018 using the prospective transition method, and it did not have a material impact to our consolidated financial statements.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, "Disclosure Update and Simplification," amending 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 is effective November 5, 2018. We early adopted this requirement as of August 1, 2018, presenting the activity of the stockholder's equity accounts in the accompanying condensed statements of redeemable convertible preferred stock and stockholders' equity (deficit) for the periods presented.

Recently Issued Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which requires lessees to recognize most leases on their balance sheets that do not meet the definition of a short-term lease but recognize the expenses on their statements of operations in a manner similar to current accounting rules. In July 2018, the FASB issued ASU 2018-10, Leases (Topic 842), Codification Improvements ("ASU 2018-10"), which clarifies certain adoption provisions of the new leases standard such as the application of implicit rate, lessee reassessment of lease classification and certain transition adjustments. In addition, in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842), Targeted Improvements ("ASU 2018-11"), which allows for the adoption of ASU 2016-02 to be applied at the beginning of the year of adoption, as opposed to at the beginning of the earliest year presented in the financial statements. These standards are effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the effect of these standards; however, we anticipate the most significant effects will relate to the recognition of right-of-use assets and lease liabilities arising from our real estate and data center operating leases that do not meet the definition of a short-term lease on the adoption date and providing qualitative and quantitative disclosures in the notes to the condensed 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. The measurement of credit losses for newly recognized financial assets and subsequent changes in the allowance for credit losses are recorded in the statements of operations. For public business entities, it is effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the potential impact of this standard on our consolidated financial statements.

We review the individual securities that have unrealized losses in our short-term investment portfolio on a regular basis to evaluate whether or not any security has experienced an other-than-temporary decline in fair value. We evaluate, among others, whether we have the intention to sell any of these investments 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. Based on this evaluation, we determined that there were no other-than-temporary impairments associated with our short-term investments as of January 31, 2019 and July 31, 2018.

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 which also 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) are classified within Level II. The fair value of these securities is priced 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.

Assets that are measured at fair value on a recurring basis consisted of the following as of January 31, 2019:


			Level I		Level II		Level III
	Total		Quoted Prices in Active Markets for Identical Assets		Significant Other Observable Inputs		Significant Unobservable Inputs

Legal Matters

Symantec Litigation

We are currently involved in legal proceedings with Symantec. On December 12, 2016, Symantec filed a complaint, which we refer to as Symantec Case 1, in the U.S. District Court for the District of Delaware alleging that "Zscaler’s cloud security platform" infringes U.S. Patent Nos. 6,279,113, 7,203,959 ("’959 patent"), 7,246,227 ("’227 patent"), 7,392,543, 7,735,116, 8,181,036 and 8,661,498. The complaint seeks compensatory damages, an injunction, enhanced damages and attorney fees. On August 2, 2017, the court granted our motion to transfer Symantec Case 1 from the District of Delaware to the Northern District of California. On March 23, 2018, the Northern District of California court granted our motion to dismiss the asserted claims of the ’959 and ’227 patents as invalid based on unpatentable subject matter.

On April 18, 2017, Symantec filed a second complaint, which we refer to as Symantec Case 2, in the U.S. District Court for the District of Delaware alleging that "Zscaler’s cloud security platform" infringes U.S. Patent Nos. 6,285,658 ("’658 patent"), 7,360,249 ("’249 patent"), 7,587,488, 8,316,429 ("’429 patent"), 8,316,446 ("’446 patent"), 8,402,540 and 9,525,696 ("’696 patent"). The complaint seeks compensatory damages, an injunction, enhanced damages and attorney fees.

On June 22, 2017, Symantec filed a notice of voluntary dismissal of its complaint in Symantec Case 2 along with a new complaint alleging infringement of the same patents and adding Symantec Limited as a plaintiff and alleging willful infringement of the ’429 and ’446 patents. On July 31, 2017, the court granted our motion to transfer Symantec Case 2 from the District of Delaware to the Northern District of California. On May 21, 2018, Symantec filed an amended complaint adding allegations of willful infringement of all of the asserted patents in Symantec Case 2. On December 12, 2018, Symantec filed a notice of voluntary dismissal with prejudice of the ’658, ’249, and ’696 Patents asserted in Symantec Case 2.

We have also received letters from Symantec alleging that our "cloud security platform" infringes U.S. Patent Nos. 7,031,327, 7,496,661, 7,543,036 and 7,624,110.

We believe that our technology does not infringe Symantec’s asserted patents and that these patents are invalid.

Should Symantec prevail with its infringement allegations, we could be required to pay substantial damages for past and future sales and/or licensing of our services, enjoined from making, using, selling or otherwise disposing of our services if a license or other right to continue selling our services is not made available to us, and required to pay substantial ongoing royalties and comply with unfavorable terms if such a license is made available to us. Any of these outcomes could result in a material adverse effect on our business. Even if we were to prevail, this litigation could be costly and time-consuming, divert the attention of our management and key personnel from our business operations, deter distributors from selling or licensing our services, and dissuade potential customers from purchasing our services, which would also materially harm our business. 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. In addition, any public announcements of the results of any proceedings in Symantec Case 1 or Case 2 could be negatively perceived by industry or financial analysts and investors, and could cause our stock price to experience volatility or decline.

We have not recorded a liability with respect to Symantec Case 1 or Case 2 based on our determination that a loss in either case is not probable under the applicable accounting standards.

We are vigorously defending Symantec Case 1 and Case 2. We are unable to predict the likelihood of success of Symantec’s infringement claims.

Finjan Litigation

We are currently involved in legal proceedings with Finjan. On December 5, 2017, Finjan filed a complaint, in the U.S. District Court for the Northern District of California alleging that Zscaler’s "Internet Access Bundles," "Private Access Bundle," "Zscaler Enforcement Node," "Secure Web Gateway," "Cloud Firewall," "Cloud Sandbox" and "Cloud Architecture products and services" infringe U.S. Patent Nos. 6,804,780, 7,647,633, 8,677,494 and 7,975,305. The complaint seeks compensatory damages, an injunction, enhanced damages and attorney fees.

We believe our technology does not infringe Finjan’s asserted patents and that Finjan’s patents are invalid.

Should Finjan prevail with its infringement allegations, we could be required to pay substantial damages for past and future sales and/or licensing of our services, enjoined from making, using, selling or otherwise disposing of our services if a license or other right to continue selling our services is not made available to us, and required to pay substantial ongoing royalties and comply with unfavorable terms if such a license is made available to us. Any of these outcomes could result in a material adverse effect on our business. Even if we were to prevail, this litigation could be costly and time-consuming, divert the attention of our management and key personnel from our business operations, deter distributors from selling or licensing our services, and dissuade potential customers from purchasing our services, which would also materially harm our business. 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. In addition, any public announcements of the results of any proceedings in this matter could be negatively perceived by industry or financial analysts and investors, and could cause our stock price to experience volatility or decline.

While the range of potential loss resulting from the lawsuit cannot be reasonably estimated, we have accrued a total liability of $3.2 million as of January 31, 2019 related to past negotiations with Finjan of which we recognized $0.7 million in fiscal 2018 and $2.5 million in fiscal 2017.

We are vigorously defending this lawsuit. We are unable to predict the likelihood of success of Finjan’s infringement claims.

Other Litigation and Claims

In addition, from time to time we are a party to various litigation matters 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. Except as otherwise described above, 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.

Temporary Equity Disclosure [Abstract]
Preferred Stock	Preferred Stock Upon completion of our IPO, as further described in Note 1, all shares of convertible preferred stock then outstanding, totaling 72,500,750 shares, were automatically converted into an equivalent number of shares of common stock on a one-to-one basis and their carrying value, totaling $207.3 million, inclusive of accretion of Series C and D redeemable convertible preferred stock of $24.7 million, was reclassified to stockholders' equity (deficit). Prior to the IPO, we recognized accretion to the redemption price of Series C and D redeemable convertible preferred stock. Accretion was recognized as a reduction of additional paid-in capital with a corresponding increase to the carrying value of Series C and D redeemable convertible preferred stock. Upon completion of the IPO, the accretion rights of Series C and D redeemable convertible preferred stock were terminated. We recognized accretion of Series C and D redeemable convertible preferred stock of $2.6 million for the three months ended January 31, 2018 and $5.1 million for the six months ended January 31, 2018.

Stock-Based Compensation

Equity Incentive Plans

We adopted the Fiscal Year 2018 Equity Incentive Plan (the "2018 Plan") in fiscal 2018 and the 2007 Stock Plan (the "2007 Plan") in fiscal 2008, collectively referred to as the "Plans." Equity incentive awards granted under the Plans may be either restricted stock units, restricted stock, stock options, nonstatutory stock options, stock appreciation rights, performance units and performance shares to our employees, directors, officers and consultants. In March 2018, in connection with our IPO, the 2007 Plan was terminated along with its remaining balance of shares of common stock available for grant. With the establishment of the 2018 Plan, we no longer grant stock-based awards under the 2007 Plan and any shares underlying stock options that expire or terminate or are forfeited or repurchased by us under the 2007 Plan will be automatically transferred to the 2018 Plan. As of January 31, 2019, we have reserved a total of approximately 18,688,000 shares of common stock for the issuance of equity awards under the 2018 Plan, of which approximately 15,815,000 shares were available for grant on such date.

Stock Options

Under the Plans, the exercise price of a stock option grant must not be less than 100% of the fair market value of the common stock on the date of grant. Generally, stock options vest over four years with 25% of the option shares vesting one year from the date of grant and monthly thereafter over the remaining vesting term. Stock options granted under the 2018 Plan and 2007 Plan are exercisable over a maximum term of ten years and seven years, respectively, from the date of grant. Stock options that are forfeited or canceled shall become available for future grant or sale under the 2018 Plan.

The activity of stock options consisted of the following:


	Outstanding Stock Options	Weighted-Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value
	(in thousands, except per share amounts)
Balance as of July 31, 2018	16,175	$	6.20	5.1	$	470,860
Stock options exercised	(3,511)	$	4.41		$	129,596
Stock options canceled, forfeited or expired	(636)	$	6.22
Balance as of January 31, 2019	12,028	$	6.72	4.9	$	500,853
Exercisable and expected to vest as of July 31, 2018	5,499	$	3.97	4.0	$	172,317
Exercisable and expected to vest as of January 31, 2019	4,055	$	4.52	4.0	$	177,830

The aggregate intrinsic value of the stock options exercised represents the difference between the fair value of our common stock on the date of exercise and their exercise price. The total intrinsic value of options exercised for the six months ended January 31, 2019 and 2018 was $129.6 million and $5.2 million, respectively. The weighted-average grant-date fair value per share of stock options granted for the six months ended January 31, 2018 was $3.12. Since our IPO, we have not granted additional stock options.

We estimated the fair value of employee stock option using the Black-Scholes option pricing model with the following assumptions.


			Six Months Ended January 31, 2018
Expected term (in years)			4.6
Expected stock price volatility			40.4% - 41.5%
Risk-free interest rate			1.7% - 2.6%
Dividend yield			0.0%

Restricted Stock Units

The 2018 Plan allows for the grant of restricted stock units ("RSUs"). Generally, RSUs are subject to a four-year vesting period, with 25% of the shares vesting one year from the date of grant and quarterly thereafter over the remaining vesting term. We began granting RSUs in the fourth quarter of fiscal 2018.

The activity of RSUs consisted of the following:


	RSUs Outstanding	Weighted-Average Grant Date Fair Value per Share		Aggregate Intrinsic Value
	(in thousands, except per share amounts)
Balance as of July 31, 2018	209	$	26.26	$	7,394
Granted	2,888	$	40.20
Vested	(3)	$	44.26	$	111
Canceled, forfeited	(57)	$	40.36
Balance as of January 31, 2019	3,037	$	39.23	$	146,897

Performance Stock Units

The 2018 Plan allows for the grant of performance stock units ("PSUs"). During the six months ended January 31, 2019, the compensation committee of our board of directors approved the grant of PSUs to certain members of our executive team corresponding to the performance periods of fiscal 2019, 2020, 2021 and 2022. In addition, the compensation committee determined and approved the corporate performance metrics for fiscal 2019. The corporate performance metrics corresponding to future fiscal years will be determined and approved in the future for each corresponding fiscal year. Holders of PSUs corresponding to the performance period of fiscal 2019 have the ability to receive up to 150% of the target number of shares granted if maximum achievement of target performance metrics is achieved. The right to receive such awards is subject to achievement of the defined corporate performance metrics corresponding for each fiscal year and continuous service by the employee. Any earned awards are subject to additional time-based vesting in accordance with the respective award agreement. Since the performance conditions of future fiscal years have not been established as of January 31, 2019, these awards are not considered granted for accounting purposes. Therefore, we have not recognized stock-based compensation expense for PSUs corresponding to fiscal years beyond 2019.

The number of unvested PSUs outstanding based on the target number of shares granted consisted of the following as of January 31, 2019:


			Underlying Shares
Performance periods			(in thousands)
Fiscal 2019			464
Fiscal 2020			464
Fiscal 2021			150
Fiscal 2022			150
Total			1,228

The activity of PSUs for which performance conditions have been established and are expected to be earned consisted of the following:


	Underlying Shares	Weighted-Average Grant Date Fair Value per Share		Aggregate Intrinsic Value
	(in thousands, except for share amounts)
Balance as of July 31, 2018	—	—		$	—
Granted	464	$	36.90

Canceled, forfeited	—	—
Balance as of January 31, 2019	464	$	36.90	$	22,456

Employee Stock Purchase Plan

We adopted the Fiscal Year 2018 Employee Stock Purchase Plan (the "ESPP") in the third quarter of fiscal 2018. As of January 31, 2019, a total of 3,397,643 shares of common stock were reserved for issuance under the ESPP. The ESPP provides eligible employees with an opportunity to purchase shares of our common stock through payroll deductions of up to 15% of their eligible compensation. A participant may purchase a maximum of 3,000 shares of common stock during a purchase period. The purchase price of the shares shall be 85% of the lower of the fair market value of our 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. 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 15 and December 15 of each year. Our first ESPP offering period commenced on March 16, 2018. During the quarter ended January 31, 2019, employees purchased approximately 627,000 shares of common stock under our employee stock purchase plan at an average purchase price of $13.86 per share, resulting in total cash proceeds of $8.7 million.

ESPP employee payroll contributions accrued at January 31, 2019 and July 31, 2018, totaled $2.2 million and $4.6 million, respectively, and are included within accrued compensation in the condensed consolidated balance sheets. Employee payroll contributions ultimately used to purchase shares under the ESPP will be reclassified to stockholders' equity on the purchase date.

The fair value of the purchase right for the ESPP is estimated on the date of grant using the Black-Scholes model with the following assumptions:


			Six Months Ended January 31, 2019
Expected term (in years)			0.5 - 2.0
Expected stock price volatility			44.0% - 61.9%
Risk-free interest rate			2.5% - 2.7%
Dividend yield			0.0%

Early Exercise of Employee Options

The 2007 Plan allowed 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 considered to be a deposit of the exercise price and is reflected as liability in the condensed consolidated balance sheets and reclassified to additional paid-in capital as the awards vest. Upon an employee’s termination, we have the option to repurchase unvested shares at a price per share equal to the lesser of the fair market value of the shares at the time of the repurchase or the original purchase price. During the six months ended January 31, 2019 and 2018, we reclassified to additional paid-in capital $0.6 million and $1.0 million, respectively, related to awards vested during these periods. As of January 31, 2019 and July 31, 2018, the number of shares of common stock subject to repurchase was 238,662 shares and 422,528 shares with an aggregate purchase price of $1.0 million and $1.6 million, respectively.

Notes Receivable from Stockholders

Prior to fiscal 2017, we entered into notes receivable agreements with certain of our current and former executives and employees in connection with the exercise of their stock options. The outstanding principal amount and related accrued interest on the notes are presented as contra-equity in the condensed consolidated balance sheets until the notes are fully settled. As of July 31, 2018, the carrying amount of the outstanding notes receivable, inclusive of accrued interest of $0.1 million, was $2.1 million. During the six months ended January 31, 2019, the principal amount and accrued interest of the outstanding notes were fully repaid, resulting in cash proceeds of $2.1 million.

Stock-based Compensation Expense

The components of stock-based compensation expense recognized in the condensed consolidated statements of operations consisted of the following:


	Three Months Ended January 31,						Six Months Ended January 31,
	2019		2018		2019		2018
	(in thousands)
Cost of revenue	$	619	$	126	1,122		$	235
Sales and marketing	5,517		985		8,318		1,770
Research and development	4,398		494		7,193		892
General and administrative	2,693		459		4,180		900
Total stock-based compensation expense	$	13,227	$	2,064	$	20,813	$	3,797

As of January 31, 2019, the unrecognized stock-based compensation cost was $148.5 million, which we expect to amortize over a weighted-average period of 3.5 years.

Income Taxes	6 Months Ended
Income Taxes	Jan. 31, 2019
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% primarily due to the earnings of our foreign subsidiaries being taxed at rates higher than the U.S. statutory rate. We recorded a provision for income taxes of $0.5 million and $0.4 million for the three months ended January 31, 2019 and 2018, respectively, and $0.9 million and $0.6 million for the six months ended January 31, 2019 and 2018, respectively. We are subject to income tax in the U.S. 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 and state deferred tax assets will not be realized. Accordingly, we have maintained a valuation allowance on our U.S. federal and state deferred tax assets. During the three months ended October 31, 2018, we determined that due to the weight of objectively verifiable negative evidence, our U.K. deferred tax assets are no longer more likely than not to be realized in the future and a full valuation allowance was recorded. We have maintained the valuation allowance for the period ended January 31, 2019. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 or the Tax Act was enacted. The Tax Act contains several key tax provisions that affect us, including, but not limited to, reducing the U.S. federal corporate tax rate from 34% to 21% imposing a one-time mandatory transition tax on previously untaxed foreign earnings, and changing rules related to the use of net operating loss carryforwards created in tax years beginning after December 31, 2017. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allows us to record provisional amounts during a measurement period not to extend beyond one year past the enactment date. We currently maintain a full valuation allowance recorded against our U.S. federal deferred tax assets. As such, the provisional estimate associated with the remeasurement of our deferred tax assets and the one-time mandatory transition tax was offset by a change in our valuation allowance which resulted in no income tax expense or benefit. During the period ended January 31, 2019, we completed our accounting for the Tax Act in accordance with SAB 118. Because of the full valuation allowance recorded against our U.S. federal deferred tax assets, there was no incremental tax expense (or benefit) recognized related to finalizing the accounting for the Tax Act. We have elected to account for the tax effects of GILTI as a period cost.

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 attributable to common stockholders as their effect is antidilutive and accordingly, basic and diluted net loss per share attributable to common stockholders is the same for all periods presented.

The following table summarizes the unweighted outstanding potentially dilutive securities that were excluded from the computation of the diluted net loss per share attributable to common stockholders because the impact of including them would have been antidilutive:
