Overview


We provide a broad portfolio of cybersecurity products, SaaS solutions and
services that allow organizations to prepare for, prevent, respond to,
investigate and remediate cyber attacks. Our product, subscription and support
solutions include security controls for network, email, endpoint and cloud
security, forensics solutions, our extended detection and response (XDR) SaaS
solution, our security validation SaaS solution, threat intelligence and
analytics solutions, our Helix security operations platform, and managed
services. Our products, SaaS solutions and managed services are complemented by
our technology-enabled Mandiant consulting services, including incident
response, security assessment and transformation services, training and
education services and expertise on demand.
In March 2020, the World Health Organization declared the novel coronavirus
disease (COVID-19) a global pandemic. We operate in geographic locations that
have been impacted by COVID-19. The pandemic has impacted, and could further
impact, our operations and the operations of our customers as a result of
quarantines, various local, state and federal government public health orders,
facility and business closures, supply chain shortages, and travel and logistics
restrictions. While we instituted a global work-from-home policy and restricted
employee travel to essential, business-critical trips toward the end of the
first quarter of 2020, we were able to maintain strong customer relationships
and deliver our technology-enabled managed and professional services to
customers without interruption. As a result, we did not incur significant
disruptions to our operations during the quarter ended March 31, 2021.
We anticipate governments and businesses may take additional actions or extend
existing actions to respond to the risks of the COVID-19 pandemic. We continue
to actively monitor the impacts and potential impacts of the COVID-19 pandemic
in all aspects of our business. Although we are unable to predict the impact of
the COVID-19 pandemic on our business, results of operations, liquidity or
capital resources at this time, we expect we may be negatively affected if the
pandemic and related public health measures result in substantial manufacturing
or supply chain problems, disruptions in local and global economies, volatility
in the global financial markets, overall reductions in demand, delays in
payment, restrictions on the shipment of our products, or other ramifications
from the COVID-19 pandemic. For a further discussion of the uncertainties and
business risks associated with the COVID-19 pandemic, see the section entitled
"Risk Factors" in Part II, Item 1A of this Quarterly Report on Form 10-Q.

Our Business Model
We generate revenue from sales of our network, email endpoint and cloud security
solutions, our security validation platform, our threat intelligence, our
managed detection and response services, our Helix security operations platform,
and our Mandiant professional services. We disaggregate our revenue into two
main categories: (i) product, subscription, and support and (ii) professional
services. For the three months ended March 31, 2021 and 2020, product,
subscription and support revenue as a percentage of total revenue was 74% and
77%, respectively. Revenue from professional services was 26% and 23% for the
three months ended March 31, 2021 and 2020, respectively.

Product, subscription and support
Within the product, subscription and support category, we provide supplemental
data to distinguish between sales of our product solutions that are deployed
on-premise (or in hybrid on-premise/private cloud configurations), and sales of
our platform, cloud-based subscriptions and managed detection and response
services. Security product solutions deployed on-premise (or in hybrid
on-premise/private cloud configurations) are included in the product and related
subscription and support sub-category. Our security validation platform, Helix
security platform, cloud-based security solutions, detection-on-demand, threat
intelligence subscriptions and managed detection and response services are
included in the platform, cloud subscription and managed services sub-category.
For the three months ended March 31, 2021 and 2020, product and related
subscription and support revenue as a percentage of total revenue was
                                       34
--------------------------------------------------------------------------------

39% and 47%, respectively. Revenue from platform, cloud subscription and managed
services was 35% and 30% for the three months ended March 31, 2021 and 2020,
respectively.
Sales of our network, email, and endpoint security solutions, platform, cloud
subscriptions and managed detection and response services, initially increase
our deferred revenue. Deferred revenue from our product, subscription and
support sales totaled $800.7 million and $845.3 million, as of March 31, 2021
and December 31, 2020, respectively. The decrease in deferred revenue from our
product, subscription and support sales was due primarily to a decrease in sales
of our appliance hardware and attached DTI cloud and support subscriptions
compared to December 31, 2020.
Product and related subscription and support
Revenue in the product and related subscription and support sub-category
consists primarily of revenue from sales of our network, email and endpoint
security solutions that are deployed on the customer's premise, either as an
integrated security appliance or in distributed hybrid on-premise/private cloud
configurations. Both deployment options are available on pre-configured
appliance hardware or as virtual sensors and include our detection and MVX
analysis technologies, our DTI cloud updates and support services.
Integrated and distributed solutions deployed on virtual sensors are offered as
an "all inclusive" subscription that includes our detection and MVX analysis
technologies, DTI cloud updates, and support services. There is no limit to the
number of virtual sensors a customer can deploy, and capacity can be distributed
throughout the customer's IT environment as needed. Subscription revenue is
recognized ratably over the contractual term, typically one to three years.
Customers purchasing our network and email security subscriptions have the
option of purchasing our appliance hardware at additional cost, but are not
required to do so.
Integrated network and email security solutions can also be deployed on
pre-configured appliance hardware purpose-built for FireEye security solutions
with scalable capacity. Integrated security appliances are delivered with
pre-installed detection and MVX analysis technologies and require subscriptions
to our DTI cloud updates and support services, which are priced as a percentage
of the appliance price per year. Subscription terms are typically one to three
years and include a material right of renewal. Historically, the majority of our
installed base of on-premise network and email security customers purchased our
solutions under this pricing model.
Since our network, email and endpoint security solutions require regular DTI
cloud and software updates to maintain detection efficacy, physical appliances
and virtual sensors, together with the related DTI cloud and support
subscriptions are considered a single performance obligation, whether deployed
as an integrated appliance, virtual sensor or in a distributed hybrid
on-premise/cloud configuration.
As a single performance obligation, revenue from sales of appliance hardware and
related subscriptions is recognized ratably over the contractual term, typically
one to three years. Such contracts typically contain a material right of renewal
option that allows the customer to renew their DTI cloud and support
subscriptions for an additional term at a discount to the original purchase
price of the single performance obligation. For contracts that contain a
material right of renewal option, the value of the performance obligation
allocated to the renewal is recognized ratably over the period between the end
of the initial contractual term and end of the estimated useful life of the
related appliance and license. A small portion of our revenue in the product and
related subscription and support revenue is derived from the sale of our network
forensics appliances and our central management system appliances. These
appliances are not dependent on regular security intelligence updates, and
revenue from these appliances is therefore recognized when ownership is
transferred to our customer, typically at shipment.
Platform, cloud subscriptions and managed services
Revenue in the platform, cloud subscription and managed services sub-category
consists primarily of revenue from sales of our cloud-based network, email and
endpoint security, our detection-on-demand service, our security validation
platform, our threat analytics platform (either standalone or within the Helix
security platform), our Helix security platform, our standalone threat
intelligence subscriptions and our managed detection and response services. The
majority of revenue from our platform, cloud subscription and managed services
category is recognized ratably over the contractual term, generally one to three
years. A small portion of our revenue in the platform, cloud subscription and
managed services category is derived from term licenses of our security
validation platform, and revenue from these sales is recognized when the license
key is issued to the customer.
Professional services
In addition to our product, subscription and support solutions, we offer
professional services, including incident response and other strategic security
consulting services, to our customers who have experienced a cybersecurity
breach or desire assistance assessing and increasing the resilience of their IT
environments to cyber-attack. The majority our professional services are offered
on a time and materials basis, through a fixed fee arrangement, or on a retainer
basis. Revenue from professional services is recognized as services are
delivered. Revenue from our Expertise-on-Demand subscription and some pre-paid
professional services is deferred, and revenue is recognized when services are
delivered. Deferred revenue from professional services as of March 31, 2021 and
December 31, 2020 was $110.0 million and $111.2 million, respectively.

Key Business Metrics
We monitor our key business metrics set forth below to help us evaluate growth
trends, establish budgets, measure the effectiveness of our sales and marketing
efforts, and assess operational efficiencies. We discuss revenue and gross
margin below under "Components of Operating Results." Deferred revenue,
annualized recurring revenue, billings (a non-GAAP metric), net cash flow
provided by (used in) operating activities, and free cash flow (a non-GAAP
metric) are discussed immediately below the following table (in thousands,
except percentages).

  Deferred revenue. Our deferred revenue consists of amounts that we have the
right to invoice but have not yet been recognized into revenue as of the end of
the respective period. We monitor our deferred revenue balance because it
represents a significant portion of revenue to be recognized in future periods.
The majority of our deferred revenue consists of the unamortized balance of
deferred revenue from previously invoiced sales of our security appliance
hardware and non-cancelable contracts for subscriptions to our network, email
and endpoint security solutions, Helix and security validation platforms, threat
intelligence, managed detection and response services and support and
maintenance contracts. Invoiced amounts for such contracts can be for multiple
years, and we classify our deferred revenue as current or non-current depending
on when we expect to recognize the related revenue. If the deferred revenue is
expected to be recognized within 12 months it is classified as current,
otherwise, the deferred revenue is classified as non-current. A table for our
deferred revenue is provided below (in thousands):
                                                     As of March 31,
                                                   2021           2020
                Deferred revenue, current       $ 587,933      $ 572,533
                Deferred revenue, non-current     322,765        347,323
                Total deferred revenue          $ 910,698      $ 919,856


Annualized recurring revenue. Annualized recurring revenue ("ARR") is an
operating metric and represents the annualized revenue run-rate of active term
licenses, subscriptions, and support contracts at the end of a reporting period.
ARR should be viewed independently of revenue and deferred revenue as ARR is an
operating metric and is not intended to be combined with or replace these items.
ARR is not a forecast of future revenue, which can be impacted by contract start
and end dates and renewal rates, and does not include revenue from appliance
hardware and its associated perpetual software, consumption-based contracts or
professional services except for service level agreement payments. We consider
ARR a useful measure of the value of the recurring components of our business
because it reflects both our ability to attract new customers for our solutions
and our success at retaining and expanding our relationships with existing
customers. Further, ARR is not impacted by variations in contract length,
enabling more meaningful comparison to prior periods as we align our invoicing
practices to growing customer preference for annual billing on multi-year
contracts. We disaggregate ARR by the same sub-categories we use for
disaggregation of billings and revenue in the table below (in thousands):
                                                         As of March 31,

Billings. Billings are a non-GAAP financial metric that we define as revenue
recognized in accordance with generally accepted accounting principles ("GAAP")
plus the change in deferred revenue from the beginning to the end of the period,
excluding deferred revenue assumed through acquisitions. We monitor billings as
a supplement to revenue (the corresponding GAAP measure), because billings
impact our deferred revenue, which is an important indicator of the health and
visibility of trends in our business and represents a significant percentage of
future revenue. However, it is important to note that other companies, including
companies in our industry, may not use billings, may define billings
differently, may have different billing frequencies, or may use other financial
measures to evaluate their performance, all of which could reduce the usefulness
of billings as a comparative measure. Additionally, the calculated billings
metric represents the total contract value we have the right to invoice, which
includes multi-year subscriptions to our solutions. Calculated billings are
impacted by changes in average contract length, thereby reducing the usefulness
of comparisons to prior periods. A reconciliation of billings to revenue, the
most directly comparable financial measure calculated and presented in
accordance with GAAP, is provided below (in thousands):

Net cash provided by (used in) operating activities. We monitor net cash
provided by (used in) operating activities as a measure of our overall business
performance. Our net cash provided by (used in) operating activities performance
is driven in large part by sales of our products and from up-front payments for
both subscriptions and support and maintenance services. Monitoring net cash
provided by (used in) operating activities enables us to analyze our financial
performance without the non-cash effects of certain items, such as depreciation,
amortization and stock-based compensation costs, thereby allowing us to better
understand and manage the cash needs of our business.
Free cash flow. Free cash flow is a non-GAAP financial measure we define as net
cash provided by (used in) operating activities, the most directly comparable
GAAP financial measure, less purchases of property and equipment and
demonstration units. We consider free cash flow to be a liquidity measure that
provides useful information to management and investors about the amount of cash
generated by our business that, after the purchases of property and equipment
and demonstration units, can be used by us for strategic opportunities,
including investing in our business, making strategic acquisitions and
strengthening our balance sheet. However, it is important to note that other
companies, including companies in our industry, may not use free cash flow, may
calculate free cash flow differently, or may use other financial measures to
evaluate their performance, all of which could reduce the usefulness of free
cash flow as a comparative measure. A reconciliation of free cash flow to cash
flow provided by (used in) operating activities is provided below (in
thousands):

Factors Affecting our Performance
Market Adoption. We rely on market education to raise awareness of today's cyber
attacks and articulate the need for our products, solutions and services. Our
prospective customers often do not have a specific portion of their IT budgets
allocated for our advanced security solutions. Additionally, the markets for
security validation software such as our Mandiant security validation platform
(formerly Verodin Security Instrumentation Platform), security operations
platforms such as FireEye Helix, and our Mandiant Defense extended detection and
response solution (formerly Respond Analyst) are in the early stages of
development.
We invest heavily in sales and marketing efforts to increase market awareness,
educate prospective customers and drive adoption of our products, solutions and
services. This market education is critical to creating new IT budget dollars or
allocating more of existing IT budget dollars to advanced threat protection,
security validation, security operations management solutions, and extended
detection and response. The degree to which prospective customers recognize the
mission critical need for our solutions will drive our ability to acquire new
customers and increase renewals and follow-on sales opportunities, which, in
turn, will affect our future financial performance.
Sales Productivity. Our sales organization consists of in-house sales teams who
work in collaboration with external channel partners to identify new sales
prospects, sell additional products, subscriptions and services, and provide
post-sale support. Our direct sales teams are organized by territory to target
large enterprise and government customers who typically have sales cycles that
can last several months or more. We have also expanded our inside sales teams to
work with channel partners to expand our customer base of small and medium
enterprises, or SMEs, as well as manage renewals of subscription and support
contracts.
Newly hired sales and marketing employees typically require several months to
establish prospect relationships and achieve full sales productivity. In
addition, although we believe our investments in market education have increased
awareness of us and our solutions globally, sales teams in certain international
markets may face local markets with limited awareness of us and our solutions,
or have specific requirements that are not available with our solutions. These
factors will influence the timing and overall levels of sales productivity,
impacting the rate at which we will be able to convert prospects to sales and
drive revenue growth.
Customer Acquisition and Retention. Since we expect that our existing customers
are likely to expand their deployments and purchase additional solutions from us
over time, we believe new customer acquisition and retention of existing
customers is important to expanding the value of our installed base, which we
monitor through our key business metrics, including annualized recurring
revenue. We believe our ability to maintain strong customer retention and drive
new customer acquisition will have a material impact on future sales of our
security solutions and services and therefore our future financial performance.
Follow-On Sales. To grow our revenue, it is important that our customers make
additional purchases of our products, subscriptions and services. After the
initial sale to a new customer, we focus on expanding our relationship with the
customer to sell additional products, subscriptions and services. Sales to our
existing customer base can take the form of incremental sales of our solutions,
managed services, and professional services either to expand their deployment of
our technologies, to extend their internal security resources with our managed
and professional security services, or continuously measure the effectiveness of
their security controls. Our opportunity to expand our customer relationships
through follow-on sales will increase as we add new customers, broaden our
security solutions portfolio with additional subscriptions and services and
enhance the functionality of our existing solutions. Follow-on sales lead to
increased revenue over the lifecycle of a customer relationship and can
significantly increase the return on our sales and marketing investments. With
many of our large enterprise and government customers, we have realized
follow-on sales that were multiples of the value of their initial purchases.
Components of Operating Results
Revenue
We generate revenue from the sales of our products, subscriptions and services.
Revenue is recognized when a contract has been entered into with a customer, the
performance obligation(s) is (are) identified, the transaction price is
determined and has been allocated to the performance obligation(s) and only then
for each performance obligation after we have satisfied that performance
obligation.
•Product, subscription and support revenue. Our product, subscription and
support revenue is generated from sales of our network, email, and endpoint
security solutions deployed on the customer's premise (or in a hybrid
on-premise/private cloud deployment), as well as our cloud-based security
solutions, threat intelligence subscriptions, security validation and Helix
security platforms, and managed detection and response services.
We combine our virtual sensors and physical appliances and software licenses
with mandatory subscriptions to our DTI cloud updates and support services as a
single performance obligation. As a result, we recognize revenue for this single
performance obligation ratably over the contractual term. Contracts containing
this single performance obligation typically contain a material right of renewal
option. For contracts that contain a material right of renewal option, the
allocated value of the performance obligation is recognized ratably over the
period between the end of the initial contractual term and the end of
                                       38
--------------------------------------------------------------------------------

the estimated useful life of the related appliance and license. Significant
judgment is required in estimating the useful life of our intelligence dependent
appliances and assessing the material rights associated with such products.
Revenue from our security validation and platform solutions, subscriptions to
our cloud-based security and intelligence solutions, and our managed detection
and response services is recognized ratably over the contractual term, typically
one to three years.
•Professional services revenue. Professional services, which includes incident
response, security assessments, and other strategic security consulting
services, are offered on a time-and-material basis, through a fixed fee
arrangement, or on a retainer basis. We recognize the associated revenue as the
services are delivered. Some professional services and our Expertise-on-Demand
subscription are prepaid, and revenue is deferred until services are delivered.
In the fourth quarter of 2020, we experienced an attack from a highly
sophisticated threat actor that targeted and accessed certain Red Team
assessment tools that we use to test our customers' security. This security
incident did not have a material adverse impact to our revenues in the three
months ended March 31, 2021. In addition, we do not expect the incident to
materially impact our revenues going forward.
Cost of Revenue
Our total cost of revenue consists of cost of product, subscription and support
revenue and cost of professional services revenue.
•Cost of product, subscription and support revenue. Cost of product,
subscription and support revenue primarily consists of costs paid to our
third-party contract manufacturers for our appliances, other costs in our
manufacturing operations department, personnel costs associated with maintaining
our threat intelligence, managed detection and response services, and global
customer support operations, and hosting costs paid to third party cloud
platform providers. Personnel costs associated with our manufacturing operations
department, our threat intelligence, our managed detection and response services
and our global customer support organization consist of salaries, benefits,
bonuses and stock-based compensation. Overhead costs consist of certain
facilities, depreciation and information technology costs. Our cost of product,
subscription and support revenue also includes product testing costs, shipping
costs and allocated overhead costs. If revenue from sales of product,
subscriptions and support declines, the cost of product, subscription and
support revenue may increase as a percentage of product, subscription and
support revenue due to the fixed nature of a portion of these costs.
Additionally, our appliance related cost of goods sold is capitalized and
amortized on a systematic basis that is consistent with the pattern of transfer
to which the asset relates.
•Cost of professional services revenue. Cost of professional services revenue
primarily consists of personnel costs for our services organization and
allocated overhead costs. If sales of our professional services decline or we
are unable to maintain our chargeability rates, our cost of professional
services revenue may increase as a percentage of professional services revenue.
Gross Margin
Gross margin, or gross profit as a percentage of revenue, has been and will
continue to be affected by a variety of factors, including our average selling
prices, the mix between products, subscription and support and services sold,
the mix of revenue among products, subscriptions and services and manufacturing
costs. We expect our gross margins to fluctuate slightly over time depending on
these factors.
Operating Expenses
Our operating expenses consist of research and development, sales and marketing
and general and administrative expenses. Personnel costs are the most
significant component of operating expenses and consist of salaries, benefits,
bonuses, stock-based compensation and, with regard to sales and marketing
expense, sales commissions. Operating expenses also include allocated overhead
costs consisting of certain facilities, depreciation and information technology
costs.
In the fourth quarter of 2020, we experienced an attack from a highly
sophisticated threat actor that targeted and accessed certain Red Team
assessment tools that we use to test our customers' security. This security
incident did not have a material adverse impact to our operating expenses during
the three months ended March 31, 2021. In addition, we do not expect the
incident to materially impact our operating expenses in future periods.
•Research and development. Research and development expense consists primarily
of personnel costs and allocated overhead. Research and development expense also
includes prototype related expenses. We expect research and development expense
to remain relatively flat in terms of absolute dollars and decrease slightly as
a percentage of total revenue.
•Sales and marketing. Sales and marketing expense consists primarily of
personnel costs, incentive commission costs and allocated overhead. Commission
costs are capitalized and amortized over the expected period of benefit, taking
into consideration the pattern of transfer to which the asset relates and the
expected renewal period. When commissions paid for
                                       39
--------------------------------------------------------------------------------

initial contracts are higher than those paid for renewal contracts, the initial
commissions are not commensurate and as such, are recognized over the expected
period of benefit. Renewal commissions are generally amortized over the renewal
period.
Sales and marketing expense also includes costs for market development programs,
promotional and other marketing activities, travel, depreciation of
proof-of-concept evaluation units and outside consulting costs. These costs are
recognized as incurred. We expect sales and marketing expense to increase in
absolute dollars and remain relatively flat or decrease slightly as a percentage
of total revenue.
•General and administrative. General and administrative expense consists of
personnel costs, professional service costs and allocated overhead. General and
administrative personnel include our executive, finance, human resources,
facilities and legal organizations. Professional service costs consist primarily
of legal, auditing, accounting and other consulting costs. We expect general and
administrative expense to stay relatively flat in terms of absolute dollars and
remain relatively flat or decrease slightly as a percentage of total revenue.
•Restructuring Charges. In April 2020, August 2020 and December 2020, we
implemented restructuring plans designed to align our resources with the
strategic initiatives of the business. These restructuring plans resulted in a
reduction of 7% of our total workforce as well as the exiting and downsizing of
certain real estate facilities and the impairment of certain assets. The
expenses incurred primarily consisted of employee severance charges and other
termination benefits, as well as real estate and related fixed asset charges for
the consolidation or exiting of certain leased facilities.
Interest Income
Interest income consists of interest earned on our cash and cash equivalent and
investment balances. We have historically invested our cash in money-market
funds and other short-term, high quality securities. We expect interest income
to vary each reporting period depending on our average cash and cash equivalent
and investment balances during the respective reporting periods, types and mix
of investments and market interest rates.
Interest Expense
Interest expense consists primarily of interest at the stated rate (coupon) and
amortization of discounts and issuance costs relating to our convertible notes.
We expect interest expense to decrease slightly as a result of the repurchase of
Series A Notes in June 2020.
Other Income (Expense), Net
Other income (expense), net includes gains or losses on the disposal of fixed
assets, gains or losses from our equity-method investment, gains or losses on
the extinguishment of convertible notes, foreign currency re-measurement gains
and losses and foreign currency transaction gains and losses. We expect other
income (expense), net to fluctuate primarily as a result of foreign exchange
rate movements.
Provision for (Benefit from) Income Taxes
Provision for income taxes relates primarily to income taxes payable in foreign
jurisdictions where we conduct business, withholding taxes, and state income
taxes in the United States. The provision is offset by tax benefits primarily
related to the reversal of valuation allowances previously established against
our deferred tax assets. Should the tax benefits exceed the provision, then a
net tax benefit from income taxes is reflected for the period. Income in certain
countries may be taxed at statutory tax rates that are lower than the U.S.
statutory tax rate. As a result, our overall effective tax rate over the
long-term may be lower than the U.S. federal statutory tax rate due to net
income being subject to foreign income tax rates that are lower than the U.S.
federal statutory rate.

Product, subscription and support revenue increased by $8.9 million, or 5%,
during the three months ended March 31, 2021 compared to the three months ended
March 31, 2020. The increase was comprised of an increase in platform, cloud
subscription and managed services revenue of $17.5 million, which was partially
offset by a decrease in product and related subscription and support revenue of
$8.5 million. The increase in platform, cloud subscription and managed services
reflected increased recognition of deferred revenue associated with sales of our
threat intelligence subscriptions, our cloud-based email and endpoint security,
our validation platform solutions, our Helix platform, and our Managed Defense
managed security service. The decrease in product and related subscription and
support revenue was primarily due to a decrease in the product and related
subscription and support deferred revenue, from which revenue is recognized. The
decrease in deferred revenue reflected a decrease in sales of our on-premise
solutions as customers migrate to cloud-based solutions.
Professional services revenue increased by $12.7 million, or 25%, during the
three months ended March 31, 2021 compared to the three months ended March 31,
2020. The increase was primarily driven by an increase in number of engagements
enabled by an increase in professional services personnel and an increase in mix
of incident response services with higher rates per hour as compared to the same
period in 2020.
Our international revenue increased $11.7 million, or 14%, during the three
months ended March 31, 2021 compared to the three months ended March 31, 2020.
The increase reflects growth in sales from certain international regions
compared to prior periods as a result of an increase in revenue recognized from
a build-up of deferred revenue from prior periods.

The cost of product, subscription and support revenue decreased by $1.2 million,
or 2%, during the three months ended March 31, 2021 compared to the three months
ended March 31, 2020. The decrease in cost of product, subscription and support
revenue was primarily due to a $0.5 million decrease in third-party cloud
hosting costs, and a $0.4 million decrease in travel and entertainment costs
which we attribute to the COVID-19 pandemic.
The cost of professional services revenue increased by $4.2 million, or 15%,
during the three months ended March 31, 2021 compared to the three months ended
March 31, 2020. The increase in cost of professional services revenue was
primarily due to a $5.1 million increase in personnel costs due to increased
headcount assigned to projects, and a $1.7 million increase in stock-based
compensation partially offset by a $1.8 million decrease in travel and
entertainment costs which we attribute to the COVID-19 pandemic.
Gross margin percentage increased by 2% during the three months ended March 31,
2021 compared to the three months ended March 31, 2020. The increase was
primarily due to lower travel and expense costs which we attribute to the
COVID-19 pandemic, efficiencies within our cloud hosting costs and a higher mix
of incident response services which carry a higher rate per hour.

Research and Development
Research and development expense increased by $4.9 million, or 7%, during the
three months ended March 31, 2021 compared to the three months ended March 31,
2020. The increase was primarily due to an increase of $3.1 million in
stock-based compensation expense, and an increase of $0.5 million in third-party
consulting costs, offset by a decrease of $0.4 million in travel and
entertainment expense which we attribute to the COVID-19 pandemic.
                                       43
--------------------------------------------------------------------------------

Sales and Marketing
Sales and marketing expense decreased by $0.6 million, or 1%, during the three
months ended March 31, 2021 compared to the three months ended March 31, 2020.
The decrease was primarily due to a decrease of $4.2 million in travel and
entertainment expense which we attribute to the COVID-19 pandemic, and a
decrease of $1.5 million in marketing program costs. These decreases were
partially offset by increases of $2.5 million in stock-based compensation
expense, $1.7 million in commissions expense and $0.5 million in consulting
costs.
General and Administrative
General and administrative expense decreased by $0.9 million, or 3%, during the
three months ended March 31, 2021 compared to the three months ended March 31,
2020. The decrease was primarily due to a decrease of $4.1 million in payroll
related costs primarily driven by lower headcount as a result of the
restructuring plans implemented in 2020, and a decrease of $0.3 million in
travel and entertainment expense which we attribute to the COVID-19 pandemic,
partially offset by an increase of $1.6 million in stock-based compensation
expense and an increase of $2.3 million in professional services costs.
Restructuring Charges
No restructuring charges were incurred during the three months ended March 31,
2021. During the three months ended March 31, 2020, we incurred restructuring
charges of approximately $11.0 million, which primarily related to employee
severance charges and other termination benefits as well as certain facilities
exit costs under our January 2020 restructuring plan.

Interest income decreased for the three months ended March 31, 2021 compared to
the three months ended March 31, 2020, due primarily to a lower rate of return
on balances in our cash and cash equivalents and investments.
Interest Expense

Interest expense decreased for the three months ended March 31, 2021 compared to
the three months ended March 31, 2020 primarily due to the repurchase of a
portion of our convertible notes in June 2020. Interest expense pertains
primarily to the amortization of discount and issuance costs related to our
convertible notes.

Other income (expense), net, increased for the three months ended March 31, 2021
compared to the three months ended March 31, 2020 primarily due to a
$1.1 million release of interest related to payroll tax liability in the three
months ended March 31, 2021.

        Effective tax rate                      (3.1)  %                   (1.2) %


The provision for income taxes increased for the three months ended March 31,
2021 compared to the three months ended March 31, 2020. The increase in the
provision for income taxes was primarily due to a tax benefit from our
acquisition of Verodin, Inc. included in the three months ended March 31, 2020
but was not in the three months ended March 31, 2021.

As of March 31, 2021, our cash and cash equivalents of $517.0 million were held
for working capital, capital expenditures, investment in technology, debt
servicing and business acquisition purposes, of which approximately $86.1
million was held outside of the United States. We consider the undistributed
earnings of our foreign subsidiaries as of March 31, 2021 to be indefinitely
reinvested outside the United States on the basis of estimates that future
domestic cash generation will be sufficient to meet future domestic cash needs
and our plan for reinvestment of our foreign subsidiaries' undistributed
earnings.
In December 2020, we issued and sold 400,000 shares of a newly designated 4.5%
Series A Convertible Preferred Stock, par value $0.0001 per share, at a price of
$1,000 per share, for an aggregate purchase price of $400.0 million.
In November 2020, we acquired Respond Software, a cybersecurity investigation
automation company. In connection with this acquisition, we paid cash
consideration of $116.1 million and assumed $5.0 million in net tangible
liabilities.
In January 2020, we acquired Cloudvisory, a provider of cloud visibility and
control solutions. Total consideration for the acquisition was $13.2 million in
cash. We also assumed $0.3 million in net tangible liabilities.
Our principal sources of liquidity are existing cash and cash equivalents and
short-term investments and any cash inflow from operations, which we believe
will be sufficient to meet our anticipated cash needs for at least the next 12
months. While we have experienced delays in collections which we attribute to
the COVID-19 pandemic, we believe we will be able to manage liquidity to meet
our anticipated cash needs for at least the next 12 months. Our future capital
requirements will depend on many factors, including our growth rate, the timing
and extent of spending to support development efforts, the efficiency of our
marketing and sales activities, the introduction of new and enhanced product and
service offerings, the cost of any future acquisitions of technology or
businesses, and the continuing market acceptance of our products. In the event
that additional financing is required from outside sources, we may not be able
to raise such financing on terms acceptable to us or at all. If we are unable to
raise additional capital when desired, our business, operating results and
financial condition would be adversely affected.

Contractual Obligations and Commitments
There have been no significant changes to our contractual obligations and

Off-Balance Sheet Arrangements
As of March 31, 2021, we did not have any relationships with unconsolidated
entities or financial partnerships, such as structured finance or special
purpose entities, which were established for the purpose of facilitating
off-balance sheet arrangements or other purposes.
Use of Estimates
Our condensed consolidated financial statements have been prepared in accordance
with U.S. generally accepted accounting principles. The preparation of these
condensed consolidated financial statements requires us to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenue,
expenses, and related disclosures. We base our estimates on historical
experience and on various other assumptions that we believe are reasonable under
the circumstances. We evaluate our estimates and assumptions on an ongoing
basis. Actual results may differ from these estimates. To the extent that there
are material differences between these estimates and our actual results, our
future financial statements will be affected.
Summary of Significant Accounting Policies
There have been no significant changes to our significant accounting policies as
of and for the three months ended March 31, 2021, as compared to the significant
accounting policies described in our Annual Report on Form 10-K for the year
