The following discussion and analysis of our financial condition and results of
operations should be read in conjunction with our condensed consolidated
financial statements and related notes included elsewhere in this Quarterly
Report on Form 10-Q and with our Management's Discussion and Analysis of
Financial Condition and Results of Operations included in our Annual Report on
Form 10-K for the year ended July 31, 2019, filed with the SEC. As discussed in
the section titled "Special Note Regarding Forward-Looking Statements," the
following discussion contains forward-looking statements that involve risks and
uncertainties. Our actual results could differ materially from those discussed
below. Factors that could cause or contribute to such difference include, but
are not limited to, those identified below and those discussed in the section
titled "Risk Factors" and elsewhere in this Quarterly Report on Form 10-Q. Our
fiscal year end is July 31, and our fiscal quarters end on October 31, January
31, April 30 and July 31. Our fiscal year ended July 31, 2019 is referred to as
fiscal 2019 and our fiscal year ending July 31, 2020 is referred to as fiscal
2020.
Overview
Zscaler was incorporated in 2007, during the early stages of cloud adoption and
mobility, based on a vision that the internet would become the new corporate
network as the cloud becomes the new data center. We predicted that with rapid
cloud adoption and increasing workforce mobility, traditional perimeter security
approaches would provide inadequate protection for users and data and an
increasingly poor user experience. We pioneered a security cloud that represents
a fundamental shift in the architectural design and approach to network
security.
We generate revenue primarily from sales of subscriptions to access our cloud
platform, together with related support services. We also generate an immaterial
amount of revenue from professional and other services, which consist primarily
of fees associated with mapping, implementation, network design and training.
Our subscription pricing is calculated on a per-user basis. We recognize
subscription and support revenue ratably over the life of the contract, which is
generally one to three years. As of July 31, 2019, we had expanded our
operations to over 3,900 customers across major industries, with users in 185
countries. Government agencies and some of the largest enterprises in the world
rely on us to help them transform to the cloud, including more than 400 of the
Forbes Global 2000 as of July 31, 2019.
We operate our business as one reportable segment. Our revenue has experienced
significant growth in recent periods. For three months ended October 31, 2019
and 2018, our revenue was $93.6 million and $63.3 million, respectively.
However, we have incurred net losses in all periods since our inception. For
three months ended October 31, 2019 and 2018, our net loss was $17.1 million and
$7.6 million, respectively. We expect we will continue to incur net losses for
the foreseeable future, as we continue investing in our sales and marketing
organization to take advantage of our market opportunity, to invest in research
and development efforts to enhance the functionality of our cloud platform, to
incur additional compliance and other related costs as we operate as a public
company, and address ongoing legal matters and related accruals, certain of
which are described in further detail in Note 8, Commitments and Contingencies,
of our condensed consolidated financial statements included elsewhere in this
Quarterly Report on Form 10-Q.
Certain Factors Affecting Our Performance
Increased Internet Traffic and Adoption of Cloud-Based Software and Security
The adoption of cloud applications and infrastructure, explosion of internet
traffic volumes and shift to mobile-first computing generally, and the pace at
which enterprises adopt the internet as their corporate network in particular,
impact our ability to drive market adoption of our cloud platform. We believe
that most enterprises are in the early stages of a broad transformation to the
cloud. Organizations are increasingly relying on the internet to operate their
businesses, deploying new SaaS applications and migrating internally managed
line-of-business applications to the cloud. However, the growing dependence on
the internet has increased exposure to malicious or compromised websites, and
sophisticated hackers are exploiting the gaps left by legacy network security
appliances. To securely access the internet and transform their networks,
                                       27
--------------------------------------------------------------------------------
  Tabl    e     of Contents
organizations must also make fundamental changes in their network and security
architectures. We believe that most organizations have yet to fully make these
investments. Since we enable organizations to securely transform to the cloud,
we believe that the imperative for organizations to securely move to the cloud
will increase demand for our cloud platform and broaden our customer base.
New Customer Acquisition
We believe that our ability to increase the number of customers on our cloud
platform is an indicator of our market penetration and our future business
opportunities. As of July 31, 2019 and 2018, we had over 3,900 and over 3,250
customers, respectively, across all major geographies. As of July 31, 2019, we
had over 400 of the Forbes Global 2000 as customers. Our ability to continue to
grow this number will increase our future opportunities for renewals and
follow-on sales. We believe that we have significant room to capture additional
market share and intend to continue to invest significantly in sales and
marketing to engage our prospective customers, increase brand awareness, further
leverage our channel partnerships and drive adoption of our solution.
Follow-On Sales
We typically expand our relationship with our customers over time. While most of
our new customers route all of their internet-bound web traffic through our
cloud platform, some of our customers initially use our services for specific
users or specific security functionality. We leverage our land-and-expand model
with the goal of generating incremental revenue, often within the term of the
initial subscription, by increasing sales to our existing customers in one of
three ways:
•expanding deployment of our cloud platform to cover additional users;
•upgrading to a more advanced Business, Transformation or Secure Transformation
suite; and
•selling a ZPA subscription to a ZIA customer, a ZIA subscription to a ZPA
customer, or other features on an a la carte basis.
Investing in Business Growth
Since our founding, we have invested significantly in growing our business. We
intend to continue (i) investing in our research and development organization
and our development efforts to offer new solutions on our platform and (ii)
dedicating resources to update and upgrade our existing solutions. In addition,
we expect our general and administrative expenses to increase in absolute
dollars in the foreseeable future, as we continue to operate as a public company
and deal with ongoing legal matters and related accruals, certain of which are
described in further detail in Note 8, Commitments and Contingencies, of our
condensed consolidated financial statements included elsewhere in this Quarterly
Report on Form 10-Q.
We also intend to continue to invest significantly in sales and marketing to
grow and train our sales force, broaden our brand awareness and expand and
deepen our channel partner relationships. While these planned investments will
increase our operating expenses in the short term, we believe that over the long
term these investments will help us to expand our customer base and grow our
business. We also are investing in programs to increase recognition of our brand
and solutions, including joint marketing activities with our channel partners
and strategic partners.
While we expect our operating expenses to increase in absolute dollars in the
foreseeable future, as a result of these activities, we intend to balance these
investments in future growth with a continued focus on managing our results of
operations and investing judiciously. In the long term we anticipate that these
investments will positively impact our business and results of operations.

Key Business Metrics and Other Financial Measures
We review a number of operating and financial metrics, including the following
key metrics, to measure our performance, identify trends, formulate business
plans and make strategic decisions.
Dollar-Based Net Retention Rate
We believe that dollar-based net retention rate is a key metric to measure the
long-term value of our customer relationships because it is driven by our
ability to retain and expand the recurring revenue generated from our existing
customers. Our dollar-based net retention rate compares the recurring revenue
from a set of customers against the same metric for the prior 12-month period on
a trailing basis. Because our customers have repeat buying patterns and the
average term of our contracts is more than 12 months, we measure this metric
over a set of customers who were with us as of the last day of the same
reporting period in the prior fiscal year. Our dollar-based net retention rate
includes customer attrition. We have not experienced a material increase in
customer attrition rates in recent periods.
We calculate our dollar-based net retention rate as follows:
Denominator: To calculate our dollar-based net retention rate as of the end of a
reporting period, we first establish the ARR from all active subscriptions as of
the last day of the same reporting period in the prior fiscal year. This
effectively represents recurring dollars that we expect in the next 12-month
period from the cohort of customers that existed on the last day of the same
reporting period in the prior fiscal year.
Numerator: We measure the ARR for that same cohort of customers representing all
subscriptions based on confirmed customer orders booked by us as of the end of
the reporting period.
Dollar-based net retention rate is obtained by dividing the numerator by the
denominator. Our dollar-based net retention rate may fluctuate due to a number
of factors, including the performance of our cloud platform; our success in
selling bigger deals for all employees with our Transformation bundle and faster
upsells within a year can reduce our dollar-based net retention rate in future
periods; the timing and the rate of ARR expansion of our existing customers;
potential changes in our rate of renewals and other risk factors described in
this Quarterly Report on Form 10-Q.

Non-GAAP Financial Measures
In addition to our results determined in accordance with U.S. GAAP, we believe
the following non-GAAP measures are useful in evaluating our operating
performance. We use the following non-GAAP financial information to evaluate our
ongoing operations and for internal planning and forecasting purposes. We
believe that non-GAAP financial information, when taken collectively, may be
helpful to investors because it provides consistency and comparability with past
financial performance. However, non-GAAP financial information is presented for
supplemental informational purposes only, has limitations as an analytical tool
and should not be considered in isolation or as a substitute for financial
information presented in accordance with U.S. GAAP. In particular, free cash
flow is not a substitute for cash used in operating activities. Additionally,
the utility of free cash flow as a measure of our liquidity is further limited
as it does not represent the total increase or decrease in our cash balance for
a given period. In addition, other companies, including companies in our
industry, may calculate similarly-titled non-GAAP measures differently or may
use other measures to evaluate their performance, all of which could reduce the
usefulness of our non-GAAP financial measures as tools for comparison. A
reconciliation is provided below for each non-GAAP financial measure to the most
directly comparable financial measure stated in accordance with U.S. GAAP.
Investors are encouraged to review the related GAAP financial measures and the

Non-GAAP Gross Profit and Non-GAAP Gross Margin
We define non-GAAP gross profit as GAAP gross profit excluding stock-based
compensation expense and amortization of acquired intangible assets. We define
non-GAAP gross margin as non-GAAP gross profit as a percentage of revenue.
                                                                  Three Months Ended October 31,

Non-GAAP Income from Operations and Non-GAAP Operating Margin
We define non-GAAP income from operations as GAAP loss from operations excluding
stock-based compensation expense, certain litigation-related expenses and
amortization expense of acquired intangible assets. We define non-GAAP operating
margin as non-GAAP income from operations as a percentage of revenue. These
excluded litigation-related expenses are professional fees and related costs
incurred by us in defending against significant claims that we deem not to be in
the ordinary course of our business and, if applicable, accruals related to
estimated losses in connection with these claims. There are many uncertainties
and potential outcomes associated with any litigation, including the expense of
litigation, timing of such expenses, court rulings, unforeseen developments,
complications and delays, each of which may affect our results of operations
from period to period, as well as the unknown magnitude of the potential loss
relating to any lawsuit, all of which are inherently subject to change,
difficult to estimate and could adversely affect our results of operations.
                                                                      Three Months Ended October 31,

Free Cash Flow and Free Cash Flow Margin
Free cash flow is a non-GAAP financial measure that we calculate as net cash
provided by (used in) operating activities less purchases of property, equipment
and other and capitalized internal-use software. Free cash flow margin is
calculated as free cash flow divided by revenue. We believe that free cash flow
and free cash flow margin are useful indicators of liquidity

that provide information to management and investors about the amount of cash
generated from our operations that, after the investments in property, equipment
and other and capitalized internal-use software, can be used for strategic
initiatives, including investing in our business, and strengthening our
financial position.
Free cash flow includes the cyclical impact of inflows and outflows resulting
from contributions to our employee stock purchase plan for which the purchase
period of approximately six months ends in each of our second and fourth fiscal
quarter. As of October 31, 2019, the employee contributions to our employee
stock purchase plan was $5.3 million, which will be reclassified to
stockholders' equity upon issuance of the shares during our second quarter of
fiscal 2020.

Calculated Billings
Calculated billings is a non-GAAP financial measure that we believe is a key
metric to measure our periodic performance. Calculated billings represents our
total revenue plus the change in deferred revenue in a period. Calculated
billings in any particular period aims to reflect amounts invoiced for
subscriptions to access our cloud platform, together with related support
services related to our new and existing customers. We typically invoice our
customers annually in advance, and to a lesser extent quarterly in advance,
monthly in advance or multi-year in advance. Calculated billings increased $23.7
million, or 37%, for the three months ended October 31, 2019 over the three
months ended October 31, 2018. As calculated billings continues to grow in
absolute terms, we expect our calculated billings growth rate to trend down over
time. We also expect that calculated billings will be affected by seasonality in
terms of when we enter into agreements with customers; and the mix of billings
in each reporting period as we typically invoice customers annually in advance,
and to a lesser extent quarterly in advance, monthly in advance or multi-year in
advance.

Components of Results of Operations
Revenue
We generate revenue primarily from sales of subscriptions to access our cloud
platform, together with related support services. These subscription and related
support services accounted for approximately 99% of our revenue for the three
months ended October 31, 2019 and 2018. Our contracts with our customers do not
at any time provide the customer with the right to take possession of the
software that runs our cloud platform. Our customers may also purchase
professional services, such as mapping, implementation, network design and
training. Professional services account for an immaterial portion of our
revenue.
We generate revenue from contracts with typical durations ranging from one to
three years. We typically invoice our customers annually in advance, and to a
lesser extent quarterly in advance, monthly in advance or multi-year in advance.
We recognize revenue ratably over the life of the contract. Amounts that have
been invoiced are recorded in deferred revenue, or they are recorded in revenue
if the revenue recognition criteria have been met. Subscriptions that are
invoiced annually in advance or multi-year in advance represent a significant
portion of our short-term and long-term deferred revenue in comparison to
invoices issued quarterly in advance or monthly in advance. Accordingly, we
cannot predict the mix of invoicing schedules in any given period.
We generally experience seasonality in terms of when we enter into agreements
with our customers. We typically enter into a higher percentage of agreements
with new customers, as well as renewal agreements with existing customers, in
our second and fourth fiscal quarters. However, because we recognize revenue
ratably over the terms of our subscription contracts, a substantial portion of
the revenue that we report in each period is attributable to the recognition of
deferred revenue relating to agreements that we entered into during previous
periods. Consequently, increases or decreases in new sales or renewals in any
one period may not be immediately reflected as revenue for that period.
Accordingly, the effect of downturns in sales and market acceptance of our
platform, and potential changes in our rate of renewals, may not be fully
reflected in our results of operations until future periods.
Cost of Revenue
Cost of revenue includes expenses related to operating our cloud platform in
data centers, depreciation of our data center equipment, related overhead costs
and the amortization of our capitalized internal-use software. Cost of revenue
also includes employee-related costs, including salaries, bonuses, stock-based
compensation expense and employee benefit costs associated with our customer
support and cloud operations organizations. Cost of revenue also includes
overhead costs for facilities, IT, and amortization and depreciation expense.
As our customers expand and increase the use of our cloud platform driven by
additional applications and connected devices, our cost of revenue will increase
due to higher bandwidth and data center expenses. However, we expect to continue
to benefit from economies of scale as our customers increase the use of our
cloud platform. We intend to continue to invest additional resources in our
cloud platform and our customer support organizations as we grow our business.
The level and timing of investment in these areas could affect our cost of
revenue in the future.
Gross Profit and Gross Margin
Gross profit, or revenue less cost of revenue, and gross margin, or gross profit
as a percentage of revenue, have been and will continue to be affected by
various factors, including the timing of our acquisition of new customers and
our renewals of and follow-on sales to existing customers, the average sales
price of our services, mix of services offered in our solutions, the data center
and bandwidth costs associated with operating our cloud platform, the extent to
which we expand our customer support and cloud operations organizations and the
extent to which we can increase the efficiency of our technology, infrastructure
and data centers through technological improvements. We expect our gross profit
to increase in

absolute dollars and gross margin to remain relatively unchanged over the
long-term, although our gross profit and gross margin could fluctuate from
period to period depending on the interplay of all of the above factors.
Operating Expenses
Our operating expenses consist of sales and marketing, research and development
and general and administrative expenses. Personnel costs are the most
significant component of operating expenses and consist of salaries, benefits,
bonuses, stock-based compensation expense and, with respect to sales and
marketing expenses, sales commissions that are recognized as expenses. Operating
expenses also include overhead costs for facilities, IT, depreciation expense
and amortization expense.
Sales and Marketing
Sales and marketing expenses consist primarily of employee compensation and
related expenses, including salaries, bonuses and benefits for our sales and
marketing employees, sales commissions that are recognized as expenses over the
period of benefit, stock-based compensation expense, marketing programs, travel
and entertainment expenses, expenses for conferences and events and allocated
overhead costs. We capitalize our sales commissions and associated payroll taxes
and recognize them as expenses over the estimated period of benefit. The amount
recognized in our sales and marketing expenses reflects the amortization of cost
previously deferred as attributable to each period presented in this Quarterly
Report on Form 10-Q, as described below under "Critical Accounting Policies and
Estimates."
We intend to continue to make significant investments in our sales and marketing
organization to drive additional revenue, further penetrate the market and
expand our global customer base. As a result, we expect our sales and marketing
expenses to continue to increase in absolute dollars and to be our largest
operating expense category for the foreseeable future. In particular, we will
continue to invest in growing and training our sales force, broadening our brand
awareness and expanding and deepening our channel partner relationships.
However, we expect our sales and marketing expenses to decrease as a percentage
of our revenue over the long term, although our sales and marketing expenses may
fluctuate as a percentage of our revenue from period to period due to the timing
and extent of these expenses.
Research and Development
Our research and development expenses support our efforts to add new features to
our existing offerings and to ensure the reliability, availability and
scalability of our solutions. Our cloud platform is software-driven, and our
research and development teams employ software engineers in the design, and the
related development, testing, certification and support, of these solutions.
Accordingly, a majority of our research and development expenses result from
employee-related costs, including salaries, bonuses and benefits, stock-based
compensation expense and costs associated with technology tools used by our
engineers. We expect our research and development expenses to continue to
increase in absolute dollars for the foreseeable future, as we continue to
invest in research and development efforts to enhance the functionality of our
cloud platform, improve the reliability, availability and scalability of our
platform and access new customer markets. However, we expect our research and
development expenses to decrease as a percentage of our revenue over the long
term, although our research and development expenses may fluctuate as a
percentage of our revenue from period to period due to the timing and extent of
these expenses.
General and Administrative
General and administrative expenses consist primarily of employee-related costs,
including salaries and bonuses, stock-based compensation expense and employee
benefit costs for our finance, legal, human resources and administrative
personnel, as well as professional fees for external legal services (including
certain litigation-related expenses), accounting and other related consulting
services. These litigation-related expenses include professional fees and
related costs incurred by us in defending significant claims that we deem not to
be in the ordinary course of our business and, if applicable, accruals

related to estimated losses in connection with these claims. We expect our
general and administrative expenses to increase in absolute dollars for the
foreseeable future, as we continue to incur compliance costs, and other related
costs necessary to operate as a public company, and due to ongoing legal matters
and related accruals, certain of which are described in further detail in Note
8, Commitments and Contingencies to our condensed consolidated financial
statements included elsewhere in this Quarterly Report on Form 10-Q. However, we
expect our general and administrative expenses to decrease as a percentage of
our revenue over the long term, although our general and administrative expenses
may fluctuate as a percentage of our revenue from period to period due to the
timing and extent of these expenses. In particular, litigation-related expenses
related to significant litigation claims may result in significant fluctuations
from period to period as they are inherently subject to change and difficult to
estimate.
Interest Income, net
Interest income consist primarily of income earned on our cash equivalents and
short-term investments and interest earned on outstanding notes receivable
extended to certain current and former employees who early exercised their stock
options. During the three months ended October 31, 2018, the principal amount
and accrued interest of the outstanding notes receivable were fully repaid. For
more information on these notes receivable, refer to Note 9, Stock-Based
Compensation, of our consolidated financial statements included elsewhere in
this Quarterly Report on Form 10-Q.
Other expense, net
Other expense, net consists primarily of foreign currency transaction gains and
losses.
Provision for Income Taxes
Our provision for income taxes consists primarily of income and withholding
taxes in the foreign jurisdictions in which we conduct business and partially
offset by the non U.S. tax benefit for excess stock-based compensation
deduction. We have not recorded any U.S. federal income tax expense. In the U.S.
we have recorded deferred tax assets for which we provide a full valuation
allowance, which includes net operating loss carryforwards and tax credits. We
expect to maintain this full valuation allowance for the foreseeable future as
it is more likely than not that some or all of those deferred tax assets may not
be realized based on our history of losses. Additionally, in the U.K., we have
recorded deferred tax assets for which we provide a full valuation allowance,
which includes net operating loss carryforwards. We expect to maintain this full
valuation allowance for the foreseeable future as it is more likely than not
that some or all of those deferred tax assets may not be realized based on our
history of losses.

Revenue increased by $30.3 million, or 48% for the three months ended October
31, 2019, compared to the three months ended October 31, 2018. The increase was
driven by an increase in users and sales of additional subscriptions to existing
customers as reflected by our dollar-based net retention rate of 120% for the
trailing 12 months ended October 31, 2019. The remainder of the increase in
revenue was attributable to the addition of new customers, which contributed
$11.7 million in revenue, as we increased our customer base by 17% from October
31, 2018 to October 31, 2019.

Cost of revenue increased by $7.5 million, or 62%, for the three months ended
October 31, 2019, compared to the three months ended October 31, 2018. The
overall increase in cost of revenue was driven primarily by the expanded use of
our cloud platform by existing and new customers, which led to an increase of
$4.1 million for data center and equipment related costs for hosting and
operating of our cloud platform for our expanded customer base. Additionally,
our employee-related expenses increased by $2.5 million, inclusive of an
increase of $0.9 million in stock-based compensation expense, driven primarily
by a 46% increase in headcount in our customer support and cloud operations
organizations from October 31, 2018 to October 31, 2019 and by the shift from
granting stock options to restricted stock units subsequent to our IPO. The
remainder of the increase was primarily attributable to increased expenses of
$0.5 million for professional fees.
Gross margin decreased from 81% during the three months ended October 31, 2018
to 79% during the three months ended October 31, 2019. The decrease in gross
margin was primarily due to increased stock-based compensation expense and, to a
lesser extent, from increased amortization expense of acquired intangible
assets.

Sales and marketing expenses increased by $22.9 million, or 63%, for the three
months ended October 31, 2019, compared to the three months ended October 31,
2018. The increase was primarily due to an increase of $14.2 million in
employee-related expenses, inclusive of an increase of $7.2 million in
stock-based compensation expense, driven by a 35% increase in headcount from
October 31, 2018 to October 31, 2019 and by the shift from granting stock
options to restricted stock units subsequent to our IPO. Additionally, our sales
and marketing expenses increased by $4.6 million primarily due to growth of
certain major sales and marketing events held during our current fiscal quarter,
including our Zenith Live events. The remainder of the increase was primarily
attributable to increased expenses of $2.0 million in sales commissions expense
and $1.8 million in travel expenses.

Research and development expenses increased by $7.1 million, or 54%, for the
three months ended October 31, 2019, compared to the three months ended October
31, 2018 as we continued to develop and enhance the functionality of our cloud
platform. The increase was primarily driven by an increase of $7.5 million in
employee-related expenses, inclusive of an increase of $2.1 million in
stock-based compensation expense, driven by a 38% increase in headcount from
October 31, 2018 to October 31, 2019 and by the shift from granting stock
options to restricted stock units subsequent to our IPO. The remainder of the
increase was primarily attributable to increased expenses of $1.6 million for
facility, IT and professional services. These increases in expense were
partially offset by decreased expenses of $2.3 million, as a result of higher
capitalized internal-use software development costs.

Interest income, net increased by $0.4 million for the three months ended

Other expense, net decreased by $0.2 million for the three months ended October

Our provision for income taxes increased by $0.5 million for the three months
ended October 31, 2019, compared to the three months ended October 31, 2018,
primarily related to income taxes in the foreign jurisdictions in which we
operate.
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 benefit of a portion of our earnings being taxed at rates lower than the
U.S. statutory rate.
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 our 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.
Liquidity and Capital Resources
As of October 31, 2019, our principal sources of liquidity were cash, cash
equivalents and short-term investments totaling $377.6 million which were held
for working capital and general corporate purposes. Our cash equivalents and
investments consist of highly liquid investments in money market funds, U.S.
treasury securities, U.S. government agency securities and corporate debt
securities.
In March 2018, upon completion of our IPO, we received net proceeds of $205.3
million, net of 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. Previously, we have financed our operations principally through
private placements of our equity securities, as well as payments received from
customers using our cloud platform and services.
We have generated significant operating losses from operations, as reflected in
our accumulated deficit of $241.5 million as of October 31, 2019. We expect to
continue to incur operating losses and have in the past and may in the future
generate negative cash flows from operations in future periods due to expected
investments to grow our business.
We believe that our existing cash, cash equivalents and short-term investments
will be sufficient to fund our operating and capital needs for at least the next
12 months from the issuance of our financial statements. Our assessment of the
period of time through which our financial resources will be adequate to support
our operations is a forward-looking statement and involves risks and
uncertainties. Our actual results could vary as a result of, and our future
capital requirements, both near-term and long-term, will depend on, many
factors, including our growth rate, the timing and extent of spending to support
our research and development efforts, the expansion of sales and marketing and
international operating activities, the timing of new introductions of solutions
or features, and the continuing market acceptance of our services. We have and
may in the future enter into arrangements to acquire or invest in complementary
businesses, services and technologies, including intellectual property rights.
We have based this estimate on assumptions that may prove to be wrong, and we
could use our available capital resources sooner than we currently expect. We
may be required to seek additional equity or debt financing. In the event that
additional financing is required from outside sources, we may not be able to
raise it on terms acceptable to us or at all. If we are unable to raise
additional capital when desired, or if we cannot expand our operations or
otherwise capitalize on our business opportunities because we lack sufficient
capital, our business, operating results and financial condition would be
adversely affected.
We typically invoice our customers annually in advance, and to a lesser extent
quarterly in advance, monthly in advance or multi-year in advance. Therefore, a
substantial source of our cash is from such prepayments, which are included on
our consolidated balance sheets as a contract liability. Deferred revenue
consists of the unearned portion of billed fees for
                                       39

our subscriptions, which is subsequently recognized as revenue in accordance
with our revenue recognition policy. As of October 31, 2019, we had deferred
revenue of $245.9 million, of which $218.2 million was recorded as a current
liability and is expected to be recorded as revenue in the next 12 months,
provided all other revenue recognition criteria have been met. Subscriptions
that are invoiced annually in advance or multi-year in advance contribute
significantly to our short-term and long-term deferred revenue in comparison to
our invoices issued quarterly in advance or monthly in advance. Accordingly, we
cannot predict the mix of invoicing schedules in any given period.
The following table summarizes our cash flows for the periods presented:

Operating Activities
Net cash provided by operating activities during the three months ended October
31, 2019 was $21.4 million, which resulted from a net loss of $17.1 million,
adjusted for non-cash charges of $30.7 million and net cash inflows of $7.8
million from changes in operating assets and liabilities. Non-cash charges
primarily consisted of $18.4 million for stock-based compensation expense, $5.5
million for amortization of deferred contract acquisition costs, $3.6 million
for depreciation and amortization expense, $2.6 million for amortization of
operating lease right-of-use assets and $0.8 million for amortization expense of
acquired intangible assets. Net cash inflows from changes in operating assets
and liabilities were primarily the result of a decrease of $22.9 million in
accounts receivable primarily due to timing of billings and collections and an
increase of $1.4 million in accrued compensation. Net cash inflows were
partially offset by cash outflows resulting from an increase of $6.2 million in
deferred contract acquisition costs, as our sales commission payments increased
due to addition of new customers and expansion of our existing customer
subscriptions, decrease of $5.3 million in deferred revenue due to billing
seasonality, an increase of $2.5 million in prepaid expenses, other current and
noncurrent assets to balance our working capital requirements, a decrease of
$2.0 million in operating lease liabilities, and a decrease of $0.5 million in
accrued expenses, other current and noncurrent liabilities.
Net cash provided by operating activities during the three months ended October
31, 2018 was $11.0 million, which resulted from a net loss of $7.6 million,
adjusted for non-cash charges of $13.9 million and net cash inflows of $4.7
million from changes in operating assets and liabilities. Non-cash charges
primarily consisted of $7.6 million for stock-based compensation expense, $4.3
million of amortization of deferred contract acquisition costs and $2.2 million
of depreciation and amortization expense. Net cash inflows from changes in
operating assets and liabilities were primarily the result of a decrease of
$12.4 million in accounts receivable primarily due to timing of billings and
collections, an increase of $2.1 million in accrued expenses, other current and
noncurrent liabilities, an increase of $1.3 million in deferred revenue from
advanced invoicing in accordance with our subscription contracts, offset by a
decrease of $4.7 million in accrued compensation, an increase of $4.4 million in
deferred contract acquisition costs as our sales commission payments increased
due to addition of new customers and expansion of our existing customer
subscriptions, an increase of $1.1 million in prepaid expenses, other current
and noncurrent assets, and a decrease of $0.8 million in accounts payable.
Investing Activities
Net cash used in investing activities during the three months ended October 31,
2019 of $33.6 million was primarily attributable to the purchases of short-term
investments of $88.4 million and capital expenditures of $12.0 million to
support

the growth of our cloud platform and investments in leasehold improvements
associated with our new corporate headquarters. These transactions were
partially offset by proceeds from the maturities of short-term investments of
$66.8 million.
Net cash used in investing activities during the three months ended October 31,
2018 of $115.3 million was primarily attributable to the purchase of short-term
investments of $137.4 million, investments in capital expenditures of $5.8
million to support our cloud platform and headcount and payments for acquired
intangible assets of $1.5 million. These activities were partially offset by
proceeds from the maturities of short-term investments of $29.3 million.
Financing Activities
Net cash provided by financing activities of $3.1 million during the three
months ended October 31, 2019 was due to proceeds from the exercise of stock
options.
Net cash provided by financing activities of $11.4 million during the three
months ended October 31, 2018 was primarily due to $9.8 million in proceeds from
the exercise of stock options, primarily as a result of the termination of our
initial public offering lock-up period ending in September 2018, and $1.9
million in proceeds from repayments of notes receivable for early exercised
stock options. Proceeds were partially offset by $0.2 million in payments of
offering costs related to our IPO.
Contractual Obligations and Commitments
During the three months ended October 31, 2019, there have been no material
changes outside the ordinary course of business to our contractual obligations
and commitments from those disclosed in Management's Discussion and Analysis of
Financial Condition and Results of Operations, set forth in Part II, Item 7, or
our Annual Report on Form 10-K for the fiscal year ended July 31, 2019 filed
with the SEC on September 18, 2019. See Note 7, Operating Leases to our
condensed consolidated financial statements included elsewhere in this Quarterly
Report on Form 10-Q for a table of our contractual obligations and commitments
as of October 31, 2019.
Off-Balance Sheet Arrangements
As of October 31, 2019, we did not have any relationships with unconsolidated
organizations or financial partnerships, such as structured finance or special
purpose entities, which would have been established for the purpose of
facilitating off-balance sheet arrangements or other contractually narrow or
limited purposes.
As of October 31, 2019, we had outstanding irrevocable standby unsecured letters
of credits for an aggregate value of $3.1 million with a bank, which serve as
security under certain real estate leases included in Note 7, Operating Leases
to our condensed consolidated financial statements included elsewhere in this
Quarterly Report on Form 10-Q.
Critical Accounting Policies and Estimates
Our financial statements are prepared in accordance with U.S. GAAP. The
preparation of these financial statements requires us to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenue and
expenses, as well as related disclosures. We evaluate our estimates and
assumptions on an ongoing basis. Our estimates are based on historical
experience and various other assumptions that we believe to be reasonable under
the circumstances. Our actual results could differ from these estimates. We
refer to accounting estimates of this type as critical accounting policies and
estimates, which we discuss below.
Our significant accounting policies are discussed in Note 1, Business and
Summary of Significant Accounting Policies to our consolidated financial
statements included in the Company's Form 10-K filed with the SEC on September
18, 2019.
