Fellow shareholders,

Mark Templeton
President and CEO

Long-standing boundaries separating economies, businesses and people are being removed, 
redrawn, and reinvented. Work is no longer a place. It’s something we do—whatever, whenever, 
wherever—to collaborate, to innovate and to grow. The consumerization of IT is eliminating the 
need for corporate-ownership of devices, networks and datacenters. Monolithic, complex systems 
are giving way to lighter, simpler, more fl exible approaches where people are at the center of 
computing—and cloud services are at their fi ngertips. 

This is precisely the kind of world we planned for.

Citrix virtual computing products and services help over a hundred million people work and play 
from anywhere—gracefully adapting to the pace of change. This is our worthy, long-term purpose, 
delivering the business agility, productivity and effi ciency needed to thrive in a very dynamic world 
where geopolitical, geophysical and geographical change is everywhere. 

Citrix has always been a company motivated by beliefs, guided by principles, and powered by 
determination. We’ve been rewarded by growth. The Citrix way is to question generally accepted 
computing assumptions, and to innovate forward. We believe our vision for virtual computing—from 
collaboration to desktops to clouds—is more valuable every day. Certainly, our record 2010 results 
support this.

Annual Report 2010 • Citrix Systems, Inc. 1

2010: another record year
2010 was a year of important milestones and record results in a range of fi nancial, operational and 
strategic dimensions. Revenue was up 16% to $1.87 billion and non-GAAP earnings per share increased 
15% to $2.08. License revenue was supported by share gains in the desktop virtualization and app 
networking markets and grew 15% over 2009. Our other revenue lines—including our online services 
business, license updates, and technical services grew 17%, 13%, and 31% respectively—helped to 
increase deferred revenue by 26% to a record $779 million.

Our focus on operational effi ciencies continued, generating a non-GAAP operating margin of 26% 
for the year, up more than two percentage points over 2009. Later, in the annual report section, you 
can fi nd a full reconciliation between our non-GAAP and GAAP performance. 

We fi nished 2010 with $1.7 billion in cash and investments on the balance sheet—up 40% for the 
year—driven by a record $616 million in total cash fl ow from operations. As a result, we had the 
fl exibility to repurchase over 8 million, or about 4%, of our outstanding shares. 

Overall, our 2010 business performance demonstrates the growing momentum in our core growth 
markets and excellence in execution. Web collaboration, desktop virtualization and cloud networking 
are being propelled by a broad set of tectonic forces reshaping the face of computing. Work is going 
virtual. Computing is going virtual. Citrix is capitalizing on these historic transformations by enabling 
better ways for people, IT and business to work.

Convergence in collaboration
Social media, web conferencing, document clouds and personal video are converging. Mass adoption 
of these integrated collaboration concepts, however, is still in early stages. So, we’re inventing and 
investing to make it easy for people to connect and work together across businesses, geographies and 
time zones. As one of the world’s top software-as-a-service, or SaaS, providers, we are leveraging the 
reach of our “GoTo” brand, its scalable SaaS platform, and our unique go-to-market know-how.

Our idea is to offer easy-to-use, economical-to-consume virtual meeting and support products that 
require zero up-front capital for customers. This is compelling, and clearly the future for many aspects 
of computing—for even the world’s largest organizations. In 2010, our collaboration business grew 
17%, representing 19% of total Citrix revenue. This growth was led by our GoToMeeting products, 
growing 33% in 2010, and achieving the #2 position in market share as measured by industry analysts.

Collaborative experiences need to be immersive, and available everywhere. So, we’ve introduced 
important innovations including “one-click meetings,” the easiest way to start an online meeting, and 
breakthrough integrated HD video we call HDFaces. We’ve also initiated geographic expansion in 
Europe, making GoToMeeting and GoToAssist available in Germany, France, Austria and Switzerland.

Annual Report 2010 • Citrix Systems, Inc. 

We’ll continue to expand our addressable market geographically and push the innovation
envelope—while keeping the user experience simple, fast and secure.

We have one of the world’s most scalable SaaS platforms, hosting tens of millions of online support 
and collaboration sessions each year. This is the kind of capacity needed to be a long-term player and 
to win. It’s why Skype recently chose the Citrix GoToMeeting platform to add web collaboration to 
their ‘Skype for Business’ solution.

Enabling the virtual desktop revolution
Virtual desktops and apps are just as essential for enabling a fl exible, virtual workstyle as collaboration. 
Demand for virtualization at the desktop is increasing, supported by force multipliers: large-scale 
migration to Windows 7; fast aging of corporate-owned PCs; extreme pressure to reduce desktop 
computing costs; greater need to assure information security; and the diverse array of consumer devices 
coming into the workplace.

These market forces helped our desktop solutions business grow 12% in 2010 to almost $1.14 billion, 
including license growth of 11%. These results were led by XenDesktop, where total revenue was 
$245 million, up over 400% for the year. Primary market demand, coupled with our innovative Trade-up 
Program, allowed us to capture over 10,000 customers, up 300% over 2009, and ship over 4 million 
XenDesktop licenses.

Many of these customers are re-thinking desktop management, moving to delivery of the desktop as an 
on-demand service—instead of a device. XenDesktop enables this, and surged into the #1 market share 
position in 2010 based on its stunning user experience, feature completeness and designed-in security. It 
works with virtually any device because of Citrix Receiver—our universal client for PCs, Macs, thin 
clients, smartphones and tablets. With a simple click or touch, people get a high fi delity user experience 
provided by Citrix HDX technologies—even over wireless connections. At the same time, our industry-
exclusive FlexCast technology allows IT professionals to enable enterprise users—from task workers to 
mobile executives.

2011 will mark another year of innovation to distance us from competitors through better design, 
broader device support, and full integration with cloud-based web and SaaS apps. IT professionals 
using our products will continue with the advantage of a system that can optimize desktop delivery 
around security, or mobility, or agility, or costs—or any mix of these. And users will continue to enjoy 
self-service apps, with an entirely new level of easy access to any Windows, SaaS or web app through a 
single click and a single login. Their apps even automatically synchronize across their devices—a Citrix 
invention we call “follow-me” apps. These are the innovations expected from the market leader.

Annual Report 2010 • Citrix Systems, Inc. 3

Cloud consumerization
Just as consumerization is fl ooding the workplace with “bring-your-own devices and apps,” the 
same phenomenon is coming to the datacenter with “bring-your-own infrastructure and SaaS.” In 
just a few clicks, cloud-based compute, storage and network infrastructure can be added—in a virtual 
way rather than physical—making new IT capacity infi nitely scalable and costs completely variable. 

Our datacenter and cloud businesses grew 29% last year, accounting for 16% of our total revenue. 
NetScaler products led this growth through product line expansion, faster performance and core 
innovation. For example, our new VPX-branded virtual appliances deliver all the power of NetScaler 
as a virtual machine on any standard Intel-based server. And, a breakthrough new feature called 
“pay-as-you-grow” means customers never pay for more capacity than they need, giving them
the economics and elasticity of the cloud in their own datacenters. The product line now spans the 
range—from small, single application virtual appliances to massive, high-end systems—all designed 
to power the world’s busiest web apps, datacenters and clouds.

The transition to public and private clouds represents a fundamental shift in how datacenter services 
are delivered—a shift Citrix is well positioned to capitalize on.

But cloud computing will not succeed under old assumptions around proprietary systems and de 
facto lock-in. In fact, enterprise customers and service providers are nervous about the “cloud wars” 
they see in proprietary cloud infrastructure promoted by every major vendor. That’s why we believe 
our “any-to-any” approach is highly differentiated. We’re making it easy to connect existing datacenters 
into ANY external cloud service, regardless of the hypervisor, network or app platform on either side.

A core technology for this is the open source Xen engine which is already the de facto platform of 
cloud computing. In fact, it powers well over two-thirds of all utility clouds today, including the 
world’s largest at Amazon. Last year, we had many early stage design wins, including with Rackspace, 
the world’s second largest cloud provider, now powered by XenServer. Recently, we announced an 
exciting new collaboration with Amazon Web Services to make cloud computing more open, more 
accessible and more secure.

All this means enterprise customers and service providers can leverage the promise of cloud computing 
without having to bet on which providers, stacks and standards will win in the long run. In other 
words, they get choice and control. In a world of MANY clouds, we’re making it possible for them 
to connect to ANY cloud with industry leading performance, security and ROI.

Looking forward
Computing as we’ve known it is facing a multitude of disruptive forces, creating unprecedented 
stress on today’s industry leaders. Citrix is not hunkering down to ride out “the storm.” We’re 
leading customers with the ideas, products and services they need to embrace the new ways people, 
IT and businesses want to work. 

We’re enabling faster Windows 7 migrations, lowering desktop refresh costs, broadening adoption 
of collaboration, and cloud-enabling datacenters. The business outcomes we impact are providing 
limitless mobility for a workforce; enabling even tighter information security controls; making 
regulatory compliance easier; accelerating merger integrations; increasing employee productivity; 
and creating a greener enterprise footprint. All of this means our customers can say “yes” to virtual 
workstyles, “yes” to consumer devices, “yes” to SaaS apps and “yes” to cloud infrastructure.

Through innovation, thought leadership, industry partnerships and our culture of belief, Citrix is 
offering our customers a bridge into the future.

We think this is the promise and the opportunity of our virtual computing platform. It’s how we’ll 
continue to deliver long-term value for shareholders, employees, partners and customers.

Last December, we celebrated 15 years as a public company. Over that time, the value of Citrix has 
grown by more than 2,300 percent. We are proud of this performance because, as we’ve always held, 
we consider our mission to deliver shareholder and customer value to be a marathon—not a sprint.

In spite of great economic uncertainty and tepid IT spending, we’re growing—in revenue, in profi tability, 
in market reach, in industry status and in strategic value to our customers. I’m proud of the entire 
Citrix team who worked tirelessly to accomplish all of this. And, we’re grateful for the thousands of 
Citrix customers and partners who continue to give us their business, their trust and their enthusiasm 
for our vision.

On behalf of the Board and our employees, we thank you for your support and confi dence.

ITEM 1. BUSINESS

General

Citrix Systems, Inc. is a Delaware corporation founded on April 17, 1989. We design, develop and market

technology solutions that enable IT services to be securely delivered on demand—independent of location,
device or network. Our customers achieve lower IT operating costs, increased information security and greater
business agility using Citrix technologies that enable virtual computing. We market and license our products
directly to enterprise customers, over the web, and through systems integrators, or SIs, in addition to indirectly
through value-added resellers, or VARs, value-added distributors, or VADs, and original equipment
manufacturers, or OEMs.

Business Overview

For over two decades, we have passionately pursued our long-term vision to enable people to work or
play—anywhere through successive waves of invention. The first wave, beginning in the early-1990s, enabled
secure remote access to mission critical applications for thousands of road warriors. This required the invention
of a new way to “transmit” application screens allowing applications to be virtualized instead of installed on the
user’s personal computer, or PC, even over very thin network connections. IT administrators found that
virtualized applications on a central server made them more secure, faster running, easier to update and much
more accessible. The shifting of computing to servers also allowed the invention of thin-clients and network
computers powered by Citrix client and server technologies. Since the early-1990s, we have become a leading
provider of server-based computing solutions and our products have been accepted by thousands of organizations
as strategic infrastructure for user mobility.

In the early 2000s, we turned our focus toward new market opportunities created by the massive

connectivity of the internet, rapid expansion of network bandwidth, and an explosion of device form factors such
as smartphones, tablet PCs and netbooks. In parallel, customers began to realize the increasing value of mobility
technologies like remote access, web collaboration and remote support tools. We also believe that there are
similar opportunities emerging in the datacenter to address high operating costs, inflexible infrastructure, and
new application architectures.

These opportunities have been the driving forces behind our second wave of invention, building on our core

ideas and technologies for virtualizing applications—extending them to adjacent product and technology
markets. Since 2004, we have focused our investments on a broader array of technologies, strategic acquisitions
and new business models. This has expanded our core capabilities beyond application virtualization to include
desktop, client and server virtualization. It has also made Citrix a leading manufacturer of network appliances
and one of the largest providers of software-as-a-service, or SaaS, in the world.

Today, Citrix serves over 230,000 customers and over 100 million users every day in over 100 countries.

Citrix products and services allow people to collaborate, communicate and work virtually anywhere—using any
device they choose. Our virtual computing infrastructure IT services are securely delivered on demand and we
believe our datacenter computing resources are simpler, lower cost and more efficient.

Invention and re-invention has driven our growth. Our diversified product lines, routes to-the-customer, and

business models have been enabled by our virtual computing products that offer collaboration as-a-service,
desktop as-a-service and infrastructure as-a-service.

Products and Services

Our products and services target customers of all sizes—from individuals who subscribe to our GoToMyPC

remote access service, to network engineers who purchase our NetScaler web application devices, or the IT
professional who licenses our XenDesktop infrastructure products. This section provides an overview of our
major product and services offerings.

Desktop Solutions

Our Desktop Solutions—XenDesktop, XenClient and XenApp—reduce the complexity and cost of

administering Windows-based applications and desktops in the enterprise.

• Citrix® XenDesktop® is a fully integrated desktop virtualization system that gives customers the

flexibility to deliver the desktop as a service—dramatically simplifying desktop management for a
broad range of users. XenDesktop is available in a range of packages designed for viral adoption and
several market segments. The Express Edition of XenDesktop is offered as a free download from our
website to allow IT professionals to conduct no-cost trials. The XenDesktop VDI Edition is designed
for virtual desktop projects that only require the hosted virtual machine method of desktop delivery.
The Enterprise and Platinum Editions of XenDesktop include all our major virtual desktop delivery
models in one integrated package, and also include the capabilities of Citrix XenApp for delivering
on-demand applications into virtual or physical desktops. All versions of XenDesktop include Citrix
HDX technologies to give users a high-definition experience—even when using multimedia, real-time
collaboration, USB devices, and 3D graphics content—while consuming 90 percent less bandwidth
than competing solutions. HDX leverages the Citrix ICA® protocol and adds Adaptive Orchestration
which helps optimize performance and bandwidth to fit each unique user scenario. Each edition comes
with user profile management and provisioning services to stream a single desktop image, on-demand,
to multiple servers in the datacenter. All editions feature licensing for both Citrix XenServer and
Microsoft Hyper-V virtualization infrastructure. The most advanced editions include our FlexCast™
delivery technologies which allow virtual desktops to be hosted in the datacenter or run locally at the
endpoint, wherever costs, security or mobility is optimal. We believe that our FlexCast technology
dramatically improves our customer’s return on their investment and makes desktop virtualization a
practical reality for broad, enterprise-wide deployments.

• Citrix® XenApp® is a widely-deployed application virtualization solution that allows enterprise

applications to be centralized and delivered as an on-demand service. XenApp delivers applications in
two ways: (1) hosted—by running application business logic on a central server using our HDX
technologies to securely transmit the application’s user experience to the endpoint device, or
(2) streamed—by running the application locally. Keeping applications under the centralized control of
IT administrators enhances data security and reduces the costs of managing separate clients and
applications on every user’s desktop. The XenApp server runs on Microsoft® Windows Server® 2008,
Windows Server® 2008 R2, Windows Server 2003 x64 Edition to Windows Server 2003, Windows®
2000 Server and several versions of UNIX®. In 2010, we announced Citrix XenApp 6, offering new
enhancements for advanced management and scalability, a rich multimedia experience over any
network and self-service applications with universal device support from PC to Mac to smartphone. We
offer XenApp as a standalone product in different editions. The Platinum Edition includes the most
features and adds powerful capabilities for application performance monitoring, secure sockets layers/
virtual private network, or SSL/VPN, advanced SmartAccess™ control and single sign-on application
security. The capabilities of XenApp are now available in XenDesktop Enterprise and Platinum

4

Editions to provide a complete desktop virtualization system. XenApp continues to be available as a
standalone solution for self-service applications on demand for customers wishing to use it on physical
PCs and with competing virtual desktop products.

Technology

Our products are based on a full range of industry-standard technologies. In addition, certain of our products

are also based on our proprietary technologies.

•

Independent Computing Architecture Protocol, or ICA®, consists of server- and client-side technology
that allows graphical user interfaces to be transmitted securely over any network, and displayed on
almost any client device. We offer client-side support for Windows-, Macintosh-, Linux-, Windows

8

Phone-, iPhone- and Android-based devices such as PCs, laptops, tablets, thin clients, netbooks and
smartphones. ICA allows applications and desktops to run on a central server enabling centralized
management of applications, desktops, end-users, servers, licenses and other system components for
greater efficiency and lower cost. ICA enhances information security by minimizing or eliminating
data from traveling across the network by sending and receiving encrypted representation of screen
pixels, keystrokes and mouse clicks. ICA is uniquely designed to consume minimal network bandwidth
and resist to network latency which allows virtual desktops and applications to be used over LANs,
WANs, WiFi and 3G connections.

• Citrix HDX Technologies is a family of innovations that optimize the end-to-end user experience in

virtual desktop and virtual application environments. These technologies incorporate our ICA protocol
and include HDX Broadcast, MediaStream, Realtime, 3D, Plug-n-Play and IntelliCache features which
work together to provide a hi-definition user experience across a wide array of applications, devices
and networks. HDX also provides Adaptive Orchestration which dynamically adjusts HDX capabilities
to adapt to specific device, network and application scenarios and to deliver a better user experience.

• NetScaler® Software Packet Engine, or the Packet Engine, forms the foundation of our NetScaler line

of products. The Packet Engine allows high-performance networking and packet processing without the
need for special purpose hardware.

• Xen® Open Source Technology is the basis for our hypervisor products, including XenClient. The Xen®
hypervisor is a key component of the XenServer™ product line. See Part I—Item 1A entitled “Risk
Factors,” for more information regarding the open source technology.

• Citrix® Internet Overlay Platform is foundational technology for GoToMeeting, GoToWebinar,

GoToTraining, GoToAssist and GoToAssist Express. The platform implements one of the largest
multicast overlay data networks in the world using the Internet. It provides proprietary screen-sharing
technology that separately optimizes screen transmission for each endpoint device (such as a remote
PC during an online meeting or remote access session).

• Citrix® PSTN/VoIP Bridge is core technology that allows the seamless integration of PSTN/VoIP audio
conferencing. This technology is used extensively in our web-based collaboration and communication
products including GoToMeeting, GoToWebinar, GoToTraining, and Hi-Def Conferencing.

• HDFaces™ in GoToMeeting® delivers high-definition video conferencing and one-to-many video

streaming over the public Internet. It includes proprietary network transport protocols and transcoding

products and go-to-market. These relationships include cross-licensing, OEM, and other arrangements that result
in better solutions for our customers.

Microsoft

Since our inception, we have had a number of license agreements with Microsoft, including patent cross-

license and source code licensing agreements that have provided us access to source code for versions of
Microsoft Windows Server. These agreements are not required for our software development processes on
Windows Server and do not provide for payments to or from Microsoft. The agreements are designed to allow
Citrix to provide technical support for our products that run on the Microsoft Windows Server platform,
including XenApp and XenDesktop. Additionally, we have collaborated with Microsoft on various technologies,
including terminal services, application networking and virtualization.

Additional Relationships

Through our Citrix Ready program, more than 15,000 products have been verified to work with Citrix
technologies. In addition, numerous partners proactively incorporate Citrix products and technologies such as
Citrix Receiver, Citrix XenServer, Citrix XenDesktop, Citrix XenClient, Citrix XenApp, Citrix NetScaler and
Citrix HDX (ICA) technology into their customer offerings. Our HDX and Citrix Receiver technologies are often

and adding value to the next generation of Microsoft Windows Server, virtualization and management products.
We incurred research and development expenses of approximately $326.6 million in 2010, $282.0 million in
2009 and $288.1 million in 2008.

Sales, Marketing and Services

We market and license our products and services through multiple channels worldwide, including VARs,

VADs, SIs, independent software vendors, or ISVs, direct over-the-web and OEMs. These distribution channels
are managed by our worldwide sales and services organization. We provide training and certification to
integrators, VARs and consultants for a full-range of Citrix-based infrastructure products, solutions and services
through our Citrix Partner Network program to members known as Citrix Solution Advisors™. In addition, our
Online Services division provides software as a service through direct corporate sales and direct over-the-web
through our websites.

We offer perpetual and term-based software licenses for our products, along with annual subscriptions for
software updates, technical support and online services. Perpetual licenses allow our customers to use the version
of software initially purchased into perpetuity, while term-based licenses are limited to a specified period of time.
Software update subscriptions give customers the right to upgrade to new software versions if and when any
updates are delivered during the subscription term. Perpetual license software products come primarily in
electronic-based forms and, in selected markets, we offer pre-packaged shrink-wrap products to meet local
customer needs. Our Online Services SaaS products are accessed over the Internet for usage during the
subscription period. Our hardware appliances come pre-loaded with software for which customers can purchase
perpetual licenses and annual support and maintenance.

In 2010, we continued to focus on increasing the productivity of our existing partners and building capacity

through recruitment of new partners to sell and implement our expanding product portfolio. Our channel
incentive program, Citrix Advisor Rewards™, is an innovative influencer program that rewards our partners for
registering projects and providing value-added selling even if they do not fulfill the product. This program has
helped limit channel conflict and increase partner loyalty to us. We regularly take actions to improve the
effectiveness of our partner programs and to strengthen our channel relationships, including managing
non-performing partners, adding new partners with expertise in selling into new markets and forming additional
relationships with global and regional SIs and ISVs. SIs and ISVs have become a more substantial part of our
strategy in the large enterprise and government markets. The SI program includes members such as Accenture
Ltd., Atos Origin, Computer Sciences Corporation, Electronic Data Systems Corporation, Fujitsu-Siemens
Computers GmbH, Hewlett-Packard Company, IBM Global Services, Infosys Technologies Limited and TATA
Consultancy Services Limited, among others. The ISV program has a strong representation from targeted
industry verticals such as healthcare, financial services and telecommunications. Members in the ISV program
include Cerner Corporation, Epic Systems Corporation, ESRI, McKesson Corporation, Microsoft, Oracle
Corporation, Sage Group plc, SAP AG and Siemens Medical Health Solutions, among many others.

Our corporate marketing organization provides sales event support, sales collateral, advertising, direct mail

and public relations coverage to our indirect channels to aid in market development and in attracting new
customers. Our partner development organization actively supports our VADs and VARs to improve their
commitment and capabilities with Citrix solutions. Our customer sales organization consists of field-based
systems sales engineers and corporate sales professionals who work directly with our largest customers and

11

coordinate integration services provided by our VARs and SIs. Additional sales personnel, working in central
locations and in the field, provide additional support including recruitment of prospective partners and technical
training with respect to our products.

Although we work with multiple VADs and VARs, one distributor, Ingram Micro, accounted for 17% of our

total net revenues in 2010, 14% of our total net revenues in 2009 and 12% of our total net revenues in 2008. Our
channel distributor arrangements with Ingram Micro consist of several non-exclusive, independently negotiated
agreements with its subsidiaries, each of which covers different countries or regions. Each of these agreements is
separately negotiated and is independent of any other contract (such as a master distribution agreement). None of
these contracts was individually responsible for over 10% of our total net revenues in each of the last three fiscal
years. In addition, there was no individual VAR that accounted for over 10% of our total net revenues in 2010,
2009 and 2008.

The Citrix Partner Network™ includes three categories of partners: Citrix Solution Advisors™, Citrix
Ready® Technology Partners, and Citrix Global SIs™. This network represents the knowledge, skills and
experience of the entire spectrum of our partners around the world, and makes it easier for end-users to engage
their services and benefit from their solutions. Equally important, the Citrix Partner Network is designed to help
partners build their business by sharing in opportunities for virtualization and networking optimization solutions
that arise from mutual customers and complement the sale of their own products.

We are not obligated to accept product returns from our channel distributors under any conditions, unless

the product item is defective in manufacture. See “Management’s Discussion and Analysis of Financial
Condition and Results of Operations—Critical Accounting Policies and Estimates” and Note 2 to our
consolidated financial statements included in this Annual Report on Form 10-K for the year ended December 31,
2010 for information regarding our revenue recognition policy.

International revenues (sales outside the United States) accounted for approximately 43% of our net

revenues for the year ended December 31, 2010, 44% of our net revenues for the year ended December 31, 2009
and 46% of our net revenues for the year ended December 31, 2008. For detailed information on our international
revenues, please refer to Note 12 to our consolidated financial statements included in this Annual Report on
Form 10-K for the year ended December 31, 2010.

Segment Revenue

During the first quarter of 2010, we changed how we measure profitability internally, develop our annual
plan and allocate our resources from a geography-based approach (which included the Americas; Europe, the
Middle East and Africa; Asia-Pacific and our Online Services division), to a product division-based approach.
This change reflects how we market and sell our products. Accordingly, we have revised our reportable segments
to reflect the way we are currently managing and viewing the business. Our revenues are derived from sales of
Enterprise division products which primarily include our Desktop Solutions, Datacenter and Cloud Solutions and
related technical services and from our Online Services division’s web collaboration, remote access and support
services. The Enterprise division and the Online Services division constitute our two reportable segments. See
Note 12 to our consolidated financial statements included in this Annual Report on Form 10-K for the year ended
December 31, 2010.

Operations

For our application networking products, including NetScaler, Access Gateway and Repeater, we employ

manufacturing capabilities that are both internal and through independent contractors to provide a redundant
source of manufacture and assembly. Internal manufacturing capabilities and independent contractors provide us
with the flexibility needed to meet our customer product and delivery requirements. We have manufacturing
relationships primarily with Flextronics, Super Micro Computer, Inc. and Hewlett Packard, under which we have
subcontracted the majority of our manufacturing activity. These third-party contract manufacturers also provide

12

final test, warehousing and shipping services. This subcontracting activity extends from prototypes to full
production and includes activities such as material procurement, final assembly, test, control, shipment to our
customers and repairs. Together with our contract manufacturers, we design, specify and monitor the tests that
are required to meet internal and external quality standards. Our contract manufacturers manufacture our
products based on forecasted demand for our products. Each of the contract manufacturers procures components
necessary to assemble the products in our forecast and test the products according to our specifications. Products
are then shipped to our channel distributors, VARs or end-users. If the products go unsold for specified periods
of time, we may incur carrying charges or obsolete material charges for products ordered to meet our forecast or
customer orders. In 2010, we did not experience any material difficulties or significant delays in the manufacture
and assembly of our products.

We control all purchasing, inventory, scheduling, order processing and accounting functions related to our
operations. For our software products, production, warehousing and shipping are performed by our independent
contractor HP, Ireland. Master software CD-ROMs, development of user manuals, packaging designs, initial
product quality control and testing are primarily performed at our facilities. In some cases, independent
contractors also duplicate CD-ROMs, print documentation and package and assemble products to our
specifications.

While it is generally our practice to promptly ship product upon receipt of properly finalized purchase
orders, we sometimes have orders that have not shipped upon receipt of a purchase order. Although the amount
of such product license orders may vary, the amount, if any, of such orders at the end of a fiscal year is not
material to our business. We do not believe that backlog, as of any particular date, is a reliable indicator of future
performance.

We believe that our fourth quarter revenues and expenses are affected by a number of seasonal factors,

including the lapse of many corporations’ fiscal year budgets and an increase in amounts paid pursuant to our
sales compensation plans due to compensation plan accelerators that are often triggered in the fourth quarter. We
believe that these seasonal factors are common within our industry. Such factors historically have resulted in first
quarter revenues in any year being lower than the immediately preceding fourth quarter. We expect this trend to
continue through the first quarter of 2011. In addition, our European operations generally generate lower
revenues in the summer months because of the generally reduced economic activity in Europe during the
summer. This seasonal factor also typically results in higher fourth quarter revenues.

Competition

We sell our products in intensely competitive markets. Some of our competitors and potential competitors

have significantly greater financial, technical, sales and marketing and other resources than we do. As the
markets for our products and services continue to develop, additional companies, including those with significant
market presence in the computer appliances, software and networking industries could enter the markets in which
we compete and further intensify competition. In addition, we believe price competition could become a more
significant competitive factor in the future. As a result, we may not be able to maintain our historic prices and
margins, which could adversely affect our business, results of operations and financial condition. See
“—Technology Relationships” and Part I—Item 1A entitled “Risk Factors.”

Desktop Solutions

We have established a very large installed customer base in the application virtualization market due to our
early success applying this solution to remote access challenges. Today, this technology is part of an evolution to
a new way of managing desktops which is establishing a larger, encompassing market defined as desktop
virtualization. Our primary competition in this market is the existing IT desktop management practice of
manually configuring physical desktops which is time-consuming, expensive and inconsistent. We also face

13

numerous competitors that provide automation of these processes and alternative approaches including
VMWare’s View product. We believe XenDesktop gives Citrix a competitive advantage by providing customers
multiple ways to manage desktops within one, integrated desktop virtualization system.

Online Services

Our SaaS products for web collaboration, remote support and remote access continue to maintain solid
leadership positions, particularly among small and medium-sized businesses, or SMBs, in extremely competitive
markets. We differentiate our SaaS products by designing simple, secure, reliable and cost-efficient services that
deliver superior customer experience. Our competitors range from large, established technology firms to small,
internet-based startups.

We have been a market leader in SaaS-based secure remote access with our GoToMyPC product for many
years. Our direct competition includes LogMeIn, free solutions such as Microsoft’s Live Mesh and those from
many internet startups. In addition, new remote access features in desktop operating systems like Microsoft
Windows and Macintosh OSX provide alternatives to our solution. We differentiate by continuing our focus on
security, ease-of-use and support for multiple desktop operating systems.

In web collaboration, we compete primarily with Cisco Systems, Inc.’s, or Cisco’s, WebEx product which

currently has the leading market share in this space. Our products, GoToMeeting and GoToWebinar, have proven
competitive based on ease-of-use and the All You Can Meet® pricing model. In 2008, we acquired an audio
services company, with advanced VoIP-based audio technology, giving us an opportunity to market audio
conference calling services directly to SMBs and enterprises. We further differentiate our collaboration products
by integrating PSTN, VoIP and toll-free audio services. We believe these features give us competitive advantage
among individual, prosumer and SMB customers. We expect to continue to expand our collaboration offerings
with GoToTraining™, an online training service purpose-built for the corporate training market.

Our on-demand support products, marketed under the GoToAssist brand, have achieved the largest market
share worldwide for Web-based clientless remote support. This product line includes versions purpose-built for
individual users, consultants and small businesses, positioning Citrix as the only provider of remote support
solutions for all segments of the market. In remote support, we compete with Cisco’s WebEx and LogMeIn.

In addition, to accelerate the European expansion of our Online Services division’s SaaS products, in

February 2011, we acquired Netviewer AG, or Netviewer, a privately held European SaaS vendor in
collaboration and IT services. Netviewer will become part of our Online Services division and enable the
extension of our SaaS leadership in Europe.

Datacenter and Cloud Solutions

In the server virtualization market, we compete directly with VMware which was first to market with this
technology and is widely regarded as the market leader. We believe XenServer, our server virtualization product,
has features that are competitive with VMware’s ESX Server in terms of performance, scalability and other
enterprise-class capabilities. XenServer is offered as a free download which significantly increases the reach of
server virtualization to customers of all sizes and geographies. In 2008, Microsoft entered this market with a
hypervisor-based server virtualization product called Hyper-V which is also available free of charge. We
monetize the XenServer and Hyper-V products by selling advanced management, storage integration and
automation capabilities offered through Citrix® Essentials™.

Our NetScaler web application delivery products compete against other established competitors including,
Cisco and F5 Networks, Inc., or F5. Both compete with us for traditional enterprise sales opportunities, while F5
is our principal competitor in the Internet-centric market segment. We continue to enhance NetScaler’s feature
capability and aggressively market NetScaler to our existing customer base.

14

Our Access Gateway or SSL/VPN product faces competition from Cisco and Juniper Networks, Inc., or
Juniper. Both competitors are well known and established in the SSL/VPN market. In contrast, we have not had a
presence in that market for as long as our competitors and we do not command the same level of brand
recognition. We do, however, have the largest market share measured in units. Our competitive success in this
market has come from bundling our SSL/VPN product with our other products, primarily XenApp, to offer a
comprehensive end-to-end virtual computing solution, a key differentiator for us.

Our Citrix Repeater family of products competes with Cisco, Riverbed Technology, Inc., or Riverbed, and
Blue Coat Systems, or Blue Coat. Cisco enjoys the largest market share, benefiting from their leadership in the
networking market. Riverbed and Blue Coat are less established companies than Citrix, but have the advantage of
being focused solely on WAN optimization. We continue to develop enhanced features and functionality for our
Citrix Repeater products, in addition to optimizing their performance with existing Citrix products, to
differentiate them from our competition. We are also able to bundle them with existing products and aggressively
market them to our installed-base, which we believe gives us a competitive advantage.

Proprietary Technology

Our success is dependent upon certain proprietary technologies and core intellectual property. We have been

awarded numerous domestic and foreign patents and have numerous pending patent applications in the United
States and foreign countries. Our technology is also protected under copyright laws. Additionally, we rely on
trade secret protection and confidentiality and proprietary information agreements to protect our proprietary
technology. We have trademarks or registered trademarks in the United States and other countries, including
Citrix®, Citrix Access Gateway™, Citrix Cloud Center™, Citrix Essentials™, Citrix Receiver™, Citrix Repeater™,
Citrix Subscription Advantage™, Citrix Synergy™, Branch Repeater®, Dazzle®, EdgeSight®, FlexCast™,
GoToAssist®, GoToMeeting®, GoToMyPC®, GoToWebinar®, GoToTraining®, GoView®, GoToLabs™,
GoToManage®, HiDef Conferencing®, HiDef Corporate®, ICA®, nCore™, NetScaler®, Simplicity is Power™,
Support Smarter®, VPX™, Xen®, XenApp®, XenCenter®, XenClient™, XenDesktop® , XenEnterprise®,
XenMotion® XenServer®, Xen Source® and Xen Summit®. While our competitive position could be affected by
our ability to protect our proprietary information, we believe that because of the rapid pace of technological
change in the industry, factors such as the technical expertise, knowledge and innovative skill of our management
and technical personnel, our technology relationships, name recognition, the timeliness and quality of support
services provided by us and our ability to rapidly develop, enhance and market software products could be more
significant in maintaining our competitive position. See Part I—Item 1A entitled “Risk Factors.”

ITEM 1A. RISK FACTORS

Our operating results and financial condition have varied in the past and could in the future vary
significantly depending on a number of factors. From time to time, information provided by us or statements
made by our employees contain “forward-looking” information that involves risks and uncertainties. In
particular, statements contained in this Annual Report on Form 10-K for the year ended December 31, 2010, and
in the documents incorporated by reference into this Annual Report on Form 10-K for the year ended
December 31, 2010, that are not historical facts, including, but not limited to, statements concerning new

program, price protection rights, proprietary technology, security measures, third party licenses, and potential
debt or equity financings constitute forward-looking statements and are made under the safe harbor provisions of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended. These statements are neither promises nor guarantees. Our actual results of operations and financial
condition have varied and could in the future vary materially from those stated in any forward-looking
statements. The following factors, among others, could cause actual results to differ materially from those
contained in forward-looking statements made in this Annual Report on Form 10-K for the year ended
December 31, 2010, in the documents incorporated by reference into this Annual Report on Form 10-K or
presented elsewhere by our management from time to time. Such factors, among others, could have a material
adverse effect upon our business, results of operations and financial condition. We caution readers not to place
undue reliance on any forward-looking statements, which only speak as of the date made. We undertake no
obligation to update any forward-looking statement to reflect events or circumstances after the date on which
such statement is made.

Adverse changes in general economic conditions in any of the major countries in which we do business,
particularly in the United States and Europe, could adversely affect our operating results.

As a global company, we are subject to the risks arising from adverse changes in global economic and
market conditions. The worldwide economy underwent unprecedented turmoil in 2008 and 2009 amid stock
market volatility, difficulties in the financial services sector, tightening of the credit markets, softness in the
housing markets, concerns of inflation and deflation, reduced corporate profits and capital spending, and
economic uncertainties. The continuing uncertainty about future economic conditions in European markets could
negatively impact our current and prospective customers and result in delays or reductions in technology
purchases. As a result, we could experience fewer orders, longer sales cycles, slower adoption of new
technologies and increased price competition, any of which could materially and adversely affect our business,
results of operations and financial condition. Adverse economic conditions also may negatively impact our
ability to obtain payment for outstanding debts owed to us by our customers or other parties with whom we do
business.

16

Our business could be adversely impacted by conditions affecting the information technology market.

The demand for our products and services depends substantially upon the general demand for business-

related computer appliances and software, which fluctuates based on numerous factors, including capital
spending levels, the spending levels and growth of our current and prospective customers, and general economic
conditions. Fluctuations in the demand for our products and services could have a material adverse effect on our
business, results of operations and financial condition. Moreover, the purchase of our products is often
discretionary and may involve a significant commitment of capital and other resources. Future economic
projections for the information technology sector are uncertain as companies continue to reassess their spending
for technology projects. In the past, adverse economic conditions decreased demand for our products and
negatively impacted our financial results. If an uncertain environment for information technology spending
continues, it could negatively impact our business, results of operations and financial condition.

Our long sales cycle for Desktop Solutions sales could cause significant variability in our revenue and
operating results for any particular period.

In recent quarters, a growing number of our large and medium-sized customers have decided to implement

our Desktop Solutions on a departmental or enterprise-wide basis. Our long sales cycle for these large-scale
deployments makes it difficult to predict when these sales will occur, and we may not be able to sustain these
sales on a predictable basis.

We have a long sales cycle for these enterprise-wide sales because:

•

•

•

•

our sales force generally needs to explain and demonstrate the benefits of a large-scale deployment of
our product to potential and existing customers prior to sale;

our service personnel typically spend a significant amount of time assisting potential customers in their
testing and evaluation of our products and services;

our customers are typically large and medium size organizations that carefully research their
technology needs and the many potential projects prior to making capital expenditures for software
infrastructure; and

before making a purchase, our potential customers usually must get approvals from various levels of
decision makers within their organizations, and this process can be lengthy.

The continued long sales cycle for these large-scale deployment sales could make it difficult to predict the

quarter in which sales will occur. Delays in sales could cause significant variability in our revenue and operating
results for any particular period. In addition, large projects with significant IT components may fail to meet our
customers’ business requirements or be canceled before delivery, which likewise could adversely affect our
revenue and operating results for any particular period.

We face intense competition, which could result in fewer customer orders and reduced revenues and margins.

We sell our products in intensely competitive markets. Some of our competitors and potential competitors
have significantly greater financial, technical, sales and marketing and other resources than we do. For example,
our ability to market our Desktop Solutions, including XenDesktop, XenApp, and other future product offerings
and upgrades, could be affected by Microsoft’s licensing and pricing scheme for client devices, servers and
applications. Further, the announcement of the release, and the actual release, of new Windows-based server
operating systems or products incorporating similar features to our products could cause our existing and
potential customers to postpone or cancel plans to license certain of our existing and future product and service
offerings. In addition, alternative products for application delivery directly and indirectly compete with our
current product lines and our online services.

Existing or new products and services that provide alternatives to our products and services, including those

relating to Desktop Solutions, Datacenter and Cloud Solutions and Online Services, including virtual desktop

17

delivery, web collaboration, IP telephony, remote support, application performance monitoring, branch office
application delivery and WAN optimization, and secure sockets layers/virtual private networks, could materially
impact our ability to compete in these markets.

Our current principal competitors in these markets include Microsoft, Cisco, including Cisco’s WebEx
division, F5, Juniper, Riverbed, VMware, Blue Coat and LogMeIn. For further discussion of the competitive
environment for our products, see the section entitled “Competition” in Part 1—Item 1.

As the markets for our products and services continue to develop, additional companies, including
companies with significant market presence in the computer appliances, software and networking industries,
could enter the markets in which we compete and further intensify competition. In addition, we believe price
competition could become a more significant competitive factor in the future. As a result, we may not be able to
maintain our historic prices and margins, which could adversely affect our business, results of operations and
financial condition.

Industry consolidation may result in increased competition.

Some of our competitors have made acquisitions or entered into partnerships or other strategic relationships
to offer a more comprehensive virtualization solution than they individually had previously offered. Additionally,
information technology companies are increasingly seeking to deliver comprehensive IT solutions to end users
that combine enterprise-level hardware and software solutions that may compete with our virtualization and web
collaboration solutions. We expect these trends to continue as IT companies attempt to strengthen or maintain
their market positions in the evolving virtualization, enterprise infrastructure and web collaboration
markets. Many of the companies that are the likely consolidators in our markets have significantly greater
financial, technical and other resources than we do and may be better positioned to acquire and offer
complementary products and services. The companies resulting from these possible combinations may create
more compelling product and service offerings and be able to offer greater pricing flexibility or sales and
marketing support for such offerings than we can. These heightened competitive pressures could result in a loss
of customers or a reduction in our revenues or revenue growth rates, all of which could adversely affect our
business, results of operations and financial condition.

If we lose key personnel or cannot hire enough qualified employees in certain areas of our business, our
ability to manage our business could be adversely affected.

Our success depends, in large part, upon the services of a number of key employees in certain areas of our

business. Except for certain key employees of acquired businesses, we do not have long-term employment
agreements with any of our key personnel. Any officer or employee can terminate his or her relationship with us
at any time. The effective management of our growth, if any, could depend upon our ability to retain our highly-
skilled managerial, technical, sales and services, finance and marketing personnel in certain areas of our
business. If any of those employees leave, we will need to attract and retain replacements for them. We also may
need to add key personnel in the future, including in certain key areas of our business. The market for these
qualified employees is competitive. We could find it difficult to successfully attract, assimilate or retain
sufficiently qualified personnel in sufficient numbers. Furthermore, we may hire key personnel in connection
with our future acquisitions; however, any of these employees will be able to terminate his or her relationship
with us at any time. If we cannot retain and add the necessary staff and resources for these acquired businesses,
our ability to develop acquired products, markets and customers could be adversely affected. Also, we may need
to hire additional personnel to develop new products, product enhancements and technologies. If we cannot add
the necessary staff and resources, our ability to develop future enhancements and features to our existing or
future products could be delayed. Any delays could have a material adverse effect on our business, results of
operations and financial condition.

18

Our Datacenter and Cloud Solutions initiatives present execution and competitive risks.

In 2010, we announced new products and technology initiatives which aim to leverage our virtualization
infrastructure software products into the emerging area of cloud computing. For example, our Citrix OpenCloud
initiative offers solutions to help our customers easily and quickly move or extend key datacenter workloads to
the cloud for increased availability and flexibility. These initiatives present new and difficult technology
challenges. Our customers may choose not to adopt our new products or services, and we may be subject to
claims if customers of these offerings experience service disruptions or failures, security breaches or other
quality issues. Further, the success of these new offerings depends upon the cooperation of third party hardware,
software and cloud hosting vendors to provide interoperability with our products and services and to offer
compatible products and services to end users.

Since the cloud computing market is in the early stages of development, we expect other companies to enter

this market and to introduce their own initiatives that may compete with, or not be compatible with, our cloud
initiatives. These competitive initiatives could limit the degree to which other vendors develop products and
services around our offerings. Additionally, our operating margins in our new initiatives may be lower than those
we have achieved in our more mature product markets, and our new initiatives may not generate sufficient
revenue to recoup our investments in them. If any of these events were to occur, it could adversely affect our
business, results of operations and financial condition.

Sales of our Desktop Solutions constitute a majority of our revenue and decreases in demand for our Desktop
Solutions could adversely affect our results of operations and financial condition.

We anticipate that sales of our Desktop Solutions and related enhancements and upgrades will constitute a
majority of our revenue for the foreseeable future. Our ability to continue to generate revenue from our Desktop
Solutions will depend on market acceptance of Windows Server Operating Systems. Declines and variability in
demand for our Desktop Solutions could occur as a result of:

•

•

•

•

•

•

new competitive product releases and updates to existing products;

termination of our product offerings and enhancements;

potential market saturation;

technological change;

general economic conditions; or

lack of success of entities with which we have a technology relationship.

If our customers do not continue to purchase our Desktop Solutions as a result of these or other factors, our

revenue would decrease and our results of operations and financial condition would be adversely affected. In
addition, modification or termination of certain of our Desktop Solutions may cause variability in our revenue
and make it difficult to predict our revenue growth and trends in our Desktop Solutions as our customers adjust
their purchasing decisions in response to such events.

Our XenDesktop products are based on an emerging technology platform, and the market for this line of
products remains uncertain, which could result in slower revenue growth than currently expected.

Our XenDesktop products and services are based on an emerging technology platform, the success of which

will depend on organizations and customers perceiving technological and operational benefits and cost savings
associated with adopting desktop virtualization solutions. The limited extent to which XenDesktop has been
adopted in the market may make it difficult to evaluate this product’s potential impact on our business because
the market for our XenDesktop products remains uncertain. For example, our primary competition in desktop
virtualization is the existing IT practice of managing physical desktops as a device. To some extent, the success
of our XenDesktop product will depend on IT executives rethinking how desktops can be delivered as a service

19

rather than viewing desktops as a device. To the extent that the adoption of desktop virtualization solutions occur
more slowly or less comprehensively than we expect, the revenue growth associated with our XenDesktop
products may be slower than currently expected, which could adversely affect our business, results of operations
and financial condition.

If we do not develop new products and services or enhancements to our existing products and services, our
business, results of operations and financial condition could be adversely affected.

The markets for our products and services are characterized by:

•

•

•

•

•

rapid technological change;

evolving industry standards;

fluctuations in customer demand;

changes in customer requirements; and

frequent new product and service introductions and enhancements.

Our future success depends on our ability to continually enhance our current products and services and
develop and introduce new products and services that our customers choose to buy. If we are unable to keep pace
with technological developments and customer demands by introducing new products and services and
enhancements, our business, results of operations and financial condition could be adversely affected. Our future
success could be hindered by:

•

•

•

delays in our introduction of new products and services;

delays in market acceptance of new products and services or new releases of our current products and
services; and

our, or a competitor’s, announcement of new product or service enhancements or technologies that
could replace or shorten the life cycle of our existing product and service offerings.

In order for a number of our products to succeed in the future, we believe the demand for technology will

need to shift from the types of products and services we and our competitors have sold in the past to a new
generation of products we now offer. For example, we cannot guarantee that our Desktop Solutions, Online
Services and Datacenter and Cloud Solutions will achieve the broad market acceptance by our channel partners
and entities with which we have a technology relationship, customers and prospective customers necessary to
generate significant revenue. In addition, we cannot guarantee that we will be able to respond effectively to
technological changes or new product announcements by others. If we experience material delays or sales
shortfalls with respect to our new products and services or new releases of our current products and services,
those delays or shortfalls could have a material adverse effect on our business, results of operations and financial
condition.

We believe that we could incur additional development costs, acquisition costs and royalties as we develop,

buy or license new technologies or enhancements to our existing products and services. These added costs and
royalties could increase our cost of revenues and operating expenses. However, we cannot currently quantify the
costs for transactions that have not yet occurred. In addition, we may need to use a significant portion of our cash
and investments to fund acquisition costs.

If we fail to manage our operations and grow revenue, our future operating results could be adversely
affected.

Historically, the scope of our operations, the number of our employees and the geographic area of our
operations and our revenue have grown rapidly. In addition, we have acquired both domestic and international
companies. This growth and the assimilation of acquired operations and their employees could continue to place

20

a significant strain on our managerial, operational and financial resources. We need to continue to implement and
improve additional management and financial systems and controls. We may not be able to manage the current
scope of our operations or future growth effectively and still exploit market opportunities for our products and
services in a timely and cost-effective way. Our future operating results could also depend on our ability to
manage:

•

•

•

our expanding product lines;

our marketing and sales organizations; and

our client support organization to the extent required for any increase in installations of our products.

During the past two years, a large portion of our growth has been attributable to the growth of our Desktop

Solutions, as well as growth in our Online Services and the application networking products in our Datacenter
and Cloud product portfolio. We cannot provide any assurance that these markets and the revenues we derive
from these markets will continue to grow or that we will realize the benefits of our Netviewer acquisition. In
addition, over the last five years we have grown our force of sales professionals that work closely with partners
to sell to primary information technology, or IT, buyers strategic IT executives, desktop operations managers, IT
infrastructure managers, network architects and server operations managers, to address the multiple selling and
buying opportunities presented by our expanded product lines. These and other account penetration efforts are
part of our strategy to increase the usage of our products within our customer’s IT organizations. We cannot
provide any assurance that this strategy will be successful or that the release of our application delivery
infrastructure products or other new products or services will sustain or increase our revenue growth rate.

We may be unable to effectively control our operating expenses, which could negatively impact our
profitability.

Although we endeavor to effectively control our operating expenses, these expenses, which are based on
estimated revenue levels, are relatively fixed in the short term. We cannot assure you that our operating expenses
will be lower than our estimated or actual revenues in any given quarter or that we will not incur unanticipated
expenses. If we experience a shortfall in revenue in any given quarter or if we incur material unanticipated
expenses, we likely will not be able to further reduce operating expenses quickly in response. Any significant
shortfall in revenue or the incurrence of material unanticipated expenses could immediately and adversely affect
our results of operations for that quarter. Also, due to the fixed nature of many of our expenses and the
challenges for revenue growth in the current environment, our income from operations and cash flows from
operating and investing activities could be lower than in recent years.

In addition, to the extent our revenue grows, if at all, we believe that our cost of revenues and certain
operating expenses could also increase. We believe that we could incur additional costs, including royalties, as
we develop, license or buy new technologies or enhancements to our existing products and services. These added
costs and royalties could increase our cost of revenues and operating expenses and lower our gross margins.
However, we cannot currently quantify the costs for such transactions that have not yet occurred or of these
developing trends in our business. In addition, we may need to use a substantial portion of our cash and
investments or issue additional shares of our common stock to fund these additional costs.

Acquisitions present many risks, and we may not realize the financial and strategic goals we anticipate at the
time of an acquisition.

Our growth is dependent upon market growth, our ability to enhance existing products and services, and our

ability to introduce new products and services on a timely basis. We intend to continue to address the need to
develop new products and services and enhance existing products and services through acquisitions of other
companies, product lines and/or technologies. However, acquisitions, including those of high-technology
companies, are inherently risky. We cannot provide any assurance that any of our previous acquisitions,

21

including our acquisition of Netviewer and our other acquisitions over the past three years, or future acquisitions
will be successful in helping us reach our financial and strategic goals either for that acquisition or for us
generally or that the combined company resulting from any acquisition will continue to support the growth
achieved by the companies separately.

The risks we commonly encounter in managing and integrating acquisitions are:

•

•

•

•

•

•

•

difficulties and delays integrating the operations, technologies, and products of the acquired
companies;

undetected errors or unauthorized use of a third-party’s code in products of the acquired companies;

the diversion of management’s attention from normal daily operations of the business;

potential difficulties in completing projects associated with purchased in-process research and
development;

entry into markets in which we have no or limited direct prior experience and where competitors have
stronger market positions and which are highly competitive;

the potential loss of key employees of the acquired company; and

an uncertain revenue and earnings stream from the acquired company, which could unexpectedly dilute
our earnings.

Our failure to manage growth effectively and successfully integrate acquired companies due to these or
other factors could have a material adverse effect on our business, results of operations and financial condition.

The financial and strategic benefits we anticipate from acquiring Netviewer may not be realized.

We acquired Netviewer with the expectation that the acquisition will result in various benefits, including,

among other things, enhanced revenue and profits, greater market presence and development, and enhancements
to our customer base. We expect that the acquisition will expand our SaaS presence in the European markets. We
may not realize any of these benefits. In addition, we may not achieve the anticipated benefits of our acquisition
of Netviewer as rapidly as, or to the extent, anticipated by our management and certain financial or industry
analysts, and others may not perceive the same benefits of the acquisition as we do. For example, Netviewer’s
contribution to our financial results may not meet the current expectations of our management for a number of
reasons, including the integration risks described above, and could dilute our profits beyond the current
expectations of our management. Operations and costs incurred and potential liabilities assumed in connection
with our acquisition of Netviewer also could have an adverse effect on our business, financial condition and
operating results. If these risks materialize, our stock price could be materially adversely affected.

Attractive acquisition opportunities may not be available to us, which could negatively affect the growth of our
business.

Our business strategy includes the selective acquisition of businesses and technologies, such as our
acquisition of Netviewer in the first quarter of 2011. We plan to continue to seek opportunities to expand our
product portfolio, customer base, technology, and technical talent through acquisitions. However, we may not
have the opportunity to make suitable acquisitions on favorable terms in the future, which could negatively
impact the growth of our business. We expect that other companies in our industry will compete with us to
acquire compatible businesses. This competition could increase prices for businesses and technologies that we
would likely pursue, and our competitors may have greater resources than we do to complete these acquisitions.

22

If we determine that any of our goodwill or intangible assets, including technology purchased in acquisitions,
are impaired, we would be required to take a charge to earnings, which could have a material adverse effect
on our results of operations.

We have a significant amount of goodwill and other intangible assets, such as product related intangible
assets, related to our acquisitions. We recorded significant additional goodwill and other intangible asset amounts
in connection with the acquisition of XenSource in 2007. We do not amortize goodwill and intangible assets that
are deemed to have indefinite lives. However, we do amortize certain product related technologies, trademarks,
patents and other intangibles and we periodically evaluate them for impairment. We review goodwill for
impairment annually, or sooner if events or changes in circumstances indicate that the carrying amount could
exceed fair value, at the reporting unit level, which for us, also represents our operating segments. As of
December 31, 2010, we had $921.1 million of goodwill. Fair values are based on discounted cash flows using a
discount rate determined by our management to be consistent with industry discount rates and the risks inherent
in our current business model. Due to uncertain market conditions and potential changes in our strategy and
product portfolio, it is possible that the forecasts we use to support our goodwill and other intangible assets could
change in the future, which could result in non-cash charges that would adversely affect our results of operations
and financial condition.

Furthermore, impairment testing requires significant judgment, including the identification of reporting
units based on our internal reporting structure that reflects the way we manage our business and operations and to
which our goodwill and intangible assets would be assigned. Significant judgments are required to estimate the
fair value of our goodwill and intangible assets, including estimating future cash flows, determining appropriate
discount rates, estimating the applicable tax rates, foreign exchange rates and interest rates, projecting the future
industry trends and market conditions, and making other assumptions. Changes in these estimates and
assumptions, including changes in our reporting structure, could materially affect our determinations of fair
value.

We recorded approximately $57.5 million of goodwill and intangible assets in connection with our

acquisitions in the three years ended December 31, 2010. If the actual revenues and operating profit attributable
to acquired intangible assets are less than the projections we used to initially value these intangible assets when
we acquired them, then these intangible assets may be deemed to be impaired. If we determine that any of the
goodwill or other intangible assets associated with our acquisitions is impaired, then we would be required to
reduce the value of those assets or to write them off completely by taking a charge to current earnings. If we are
required to write down or write off all or a portion of those assets, or if financial analysts or investors believe we
may need to take such action in the future, our stock price and operating results could be materially and adversely
affected.

At December 31, 2010, we had $178.1 million of unamortized intangibles, which include product related
technology we purchased in acquisitions or under third-party licenses. These intangibles are primarily associated
with our Datacenter and Cloud Solutions. However, our value added resellers, or VADs, and entities with which
we have technology relationships, customers or prospective customers may not purchase or widely accept our
new products. If we fail to complete the development of our anticipated future product and service offerings,
including product offerings acquired through our acquisitions, if we fail to complete them in a timely manner, or
if we are unsuccessful in selling any new lines of products, appliances and services, we could determine that the
value of the purchased technology is impaired in whole or in part and take a charge to earnings. We could also
incur additional charges in later periods to reflect costs associated with completing those projects that could not
be completed in a timely manner. An impairment charge could have a material adverse effect on our results of
operations. If the actual revenues and operating profit attributable to acquired product and core technologies are
less than the projections we used to initially value product and core technologies when we acquired them, such
intangible assets may be deemed to be impaired. If we determine that any of our intangible assets are impaired,
we would be required to take a related charge to earnings that could have a material adverse effect on our results
of operations.

23

Our business could be adversely affected if we are unable to expand and diversify our distribution channels.

We currently intend to continue to expand our distribution channels by leveraging our relationships with

independent hardware and software vendors and system integrators to encourage them to recommend or
distribute our products. In addition, an integral part of our strategy is to diversify our base of channel
relationships by adding and training more channel members with abilities to reach larger enterprise customers
and to sell our newer products. This strategy will require additional resources, as we will need to expand our
internal sales and service coverage of these customers. If we fail in these efforts and cannot expand, train or
diversify our distribution channels, our business could be adversely affected. In addition to this diversification of
our base, we will need to maintain a healthy mix of channel members who cater to smaller customers. We may
need to add and remove distribution members to maintain customer satisfaction and a steady adoption rate of our
products, which could increase our operating expenses. Through our Citrix Partner Network and other programs,
we are currently investing, and intend to continue to invest, significant resources to develop these channels,
which could reduce our profits.

Our investment portfolio has been subject to impairment charges due to the financial crisis of 2008 in the
capital markets and may be adversely impacted by volatility in the capital markets.

Our investment portfolio as of December 31, 2010 primarily consisted of agency securities, corporate
securities, government securities, commercial paper and municipal securities. As a result of adverse financial
market conditions in 2008 and 2009, investments in some financial instruments posed risks arising from liquidity
and credit concerns. Future adverse market conditions and volatility could create similar risks for investments in
financial instruments. Although we follow an established investment policy and seek to minimize the credit risk
associated with investments by investing primarily in investment grade, highly liquid securities and by limiting
exposure to any one issuer depending on credit quality, we cannot give any assurances that the assets in our
investment portfolio will not lose value, become impaired, or suffer from illiquidity.

We may be required to record impairment charges for other-than-temporary declines in fair market value in
our available-for-sale investments, including our investment issued by AIG Matched Funding Corporation, or the
AIG Capped Floater. Future market conditions and volatility could lead to additional impairment charges, which
could adversely affect our results of operations. Moreover, fluctuations in economic and market conditions could
adversely affect the market value of our investments, and we could lose some of the principal value of our
investment portfolio. A total loss of an investment, dependent on an individual security’s par value, or a
significant decline in the value of our investment portfolio could adversely affect our financial condition.

We could change our licensing programs or subscription renewal programs, which could negatively impact
the timing of our recognition of revenue.

We continually re-evaluate our licensing programs and subscription renewal programs, including specific

license models, delivery methods, and terms and conditions, to market our current and future products and
services. We could implement new licensing programs and subscription renewal programs, including
promotional trade-up programs or offering specified enhancements to our current and future product and service
lines. Such changes could result in deferring revenue recognition until the specified enhancement is delivered or
at the end of the contract term as opposed to upon the initial shipment or licensing of our software product. We
could implement different licensing models in certain circumstances, for which we would recognize licensing
fees over a longer period, including offering additional products in a software-as-a-service model. Changes to our
licensing programs and subscription renewal programs, including the timing of the release of enhancements,
upgrades, maintenance releases, the term of the contract, discounts, promotions and other factors, could impact
the timing of the recognition of revenue for our products, related enhancements and services and could adversely
affect our operating results and financial condition.

24

Sales of our Subscription Advantage product constitute substantially all of our License Updates revenue and a
large portion of our deferred revenue.

We anticipate that sales of our Subscription Advantage product will continue to constitute a substantial
portion of our License Updates revenue. Our ability to continue to generate both recognized and deferred revenue
from our Subscription Advantage product will depend on our customers continuing to perceive value in
automatic delivery of our software upgrades and enhancements. A decrease in demand for our Subscription
Advantage product could occur as a result of a decrease in demand for our Desktop Solutions and our Datacenter
and Cloud Solutions. If our customers do not continue to purchase our Subscription Advantage product, our
License Updates revenue and deferred revenue would decrease significantly and our results of operations and
financial condition would be adversely affected.

As our international sales and operations grow, we could become increasingly subject to additional risks that
could harm our business.

We conduct significant sales and customer support, development and engineering operations in countries

outside of the United States. During the year ended December 31, 2010, we derived approximately 42.7% of our
revenues from sales outside the United States. Our continued growth and profitability could require us to further
expand our international operations. To successfully expand international sales, we must establish additional
foreign operations, hire additional personnel and recruit additional international resellers. In addition, there is
significant competition for entry into high growth markets, such as China. Our international operations are
subject to a variety of risks, which could cause fluctuations in the results of our international operations. These
risks include:

•

•

•

•

•

•

•

•

compliance with foreign regulatory and market requirements;

variability of foreign economic, political and labor conditions;

changing restrictions imposed by regulatory requirements, tariffs or other trade barriers or by U.S.
export laws;

longer accounts receivable payment cycles;

potentially adverse tax consequences;

difficulties in protecting intellectual property;

burdens of complying with a wide variety of foreign laws; and

as we generate cash flow in non-U.S. jurisdictions, if required, we may experience difficulty
transferring such funds to the U.S. in a tax efficient manner.

Our results of operations are also subject to fluctuations in foreign currency exchange rates. In order to
minimize the impact on our operating results, we generally initiate our hedging of currency exchange risks one
year in advance of anticipated foreign currency expenses for those currencies to which we have the greatest
exposure. When the dollar is weak, foreign currency denominated expenses will be higher, and these higher
expenses will be partially offset by the gains realized from our hedging contracts. If the dollar is strong, foreign
currency denominated expenses will be lower. These lower expenses will in turn be partially offset by the losses
incurred from our hedging contracts. There is a risk that there will be fluctuations in foreign currency exchange
rates beyond the one year timeframe for which we hedge our risk.

Our success depends, in part, on our ability to anticipate and address these risks. We cannot guarantee that

these or other factors will not adversely affect our business or operating results.

Unanticipated changes in our tax rates or our exposure to additional income tax liabilities could affect our
operating results and financial condition.

Our future effective tax rates could be favorably or unfavorably affected by unanticipated changes in the

valuation of our deferred tax assets and liabilities, the geographic mix of our revenue, or by changes in tax laws

25

or their interpretation. Significant judgment is required in determining our worldwide provision for income taxes.
In addition, we are subject to the continuous examination of our income tax returns by tax authorities, including
the examination of our income tax returns for 2004 and 2005 by the Internal Revenue Service, or IRS, which
concluded during the third quarter of 2009. We regularly assess the likelihood of adverse outcomes resulting
from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance,
however, that the outcomes from these continuous examinations will not have an adverse effect on our operating
results and financial condition. Additionally, due to the evolving nature of tax rules combined with the large
number of jurisdictions in which we operate, it is possible that our estimates of our tax liability and the
realizability of our deferred tax assets could change in the future, which may result in additional tax liabilities
and adversely affect our results of operations, financial condition and cash flows.

In June 2010, we reached a settlement in principle with the IRS regarding previously disclosed income tax

deficiencies asserted in a Revenue Agent’s Report issued by the IRS. The final settlement requires the
finalization of tax deficiency calculations with the IRS and a written agreement signed by the IRS. It is uncertain
how long it will take to reach a final settlement with the IRS, and there can be no assurances that a final written
agreement will be obtained or that this matter will otherwise be resolved in our favor. An adverse outcome of this
matter could have a material adverse effect on our results of operations and financial condition.

We have credit exposure to our hedging counterparties, which could result in our failure to recover
anticipated net gains from hedging transactions.

In order to minimize volatility in earnings associated with fluctuations in the value of foreign currency
relative to the U.S. dollar, we use financial instruments to hedge our exposure to foreign currencies as we deem
appropriate for a portion of our expenses which are denominated in the local currency of our foreign subsidiaries.
As a result of entering into these contracts with counterparties who are unrelated to us, the risk of a counterparty
default exists in fulfilling the hedge contract. Should there be a counterparty default, we could be unable to
recover anticipated net gains from the transactions.

Security vulnerabilities in our products could have a material adverse impact on our results of operations.

Maintaining the security of computing devices and networks is a critical issue for us and our customers. We

devote significant resources to address security vulnerabilities in our products and services through engineering
more secure products and services, enhancing security and reliability features in our products and services,
deploying security updates to address security vulnerabilities and seeking to respond to known security incidents
in sufficient time to minimize any potential adverse impact. The cost of these measures could reduce our
operating margins. Despite these efforts, actual or perceived security vulnerabilities in our products and systems
may lead to claims against us and harm our reputation, and could lead some customers to seek to return products,
to stop using certain products or services, to reduce or delay future purchases of our products or services, or to
use competing products or services. Customers may also increase their expenditures on protecting their existing
computer systems from attack, which could delay adoption of new technologies. Further, if our customers suffer
any losses or are otherwise harmed in connection with a security incident related to our products or services, we
could be subject to liability claims from our customers. Any of these actions by customers could adversely
impact our results of operations.

Our efforts to protect our intellectual property may not be successful, which could materially and adversely
affect our business.

We rely primarily on a combination of copyright, trademark, patent and trade secret laws, confidentiality

procedures and contractual provisions to protect our source code and other intellectual property. The loss of any
material trade secret, trademark, tradename, patent or copyright could have a material adverse effect on our
business. Despite our precautions, it could be possible for unauthorized third parties to copy, disclose or reverse
engineer certain portions of our products or to otherwise obtain and use our proprietary source code, in which

26

case we could potentially lose future trade secret protection for that source code. If we cannot protect our
proprietary source code against unauthorized copying, disclosure or use, unauthorized third parties could develop
products similar to or better than ours.

Any patents owned by us also could be invalidated, circumvented or challenged. Any of our pending or
future patent applications, whether or not being currently challenged, may not be issued with the scope we seek,
if at all; and if issued, may not provide any meaningful protection or competitive advantage.

In addition, our ability to protect our proprietary rights could be affected by differences in international law
and the enforceability of licenses. The laws of some foreign countries do not protect our intellectual property to
the same extent as do the laws of the United States and Canada. For example, we derive a significant portion of
our sales from licensing our products under “click-to-accept” license agreements that are not signed by licensees
and electronic enterprise customer licensing arrangements that are delivered electronically, all of which could be
unenforceable under the laws of many foreign jurisdictions in which we license our products.

Our products, including products obtained through acquisitions, could infringe third-party intellectual
property rights, which could result in material litigation costs.

We are increasingly subject to infringement claims and may in the future be subject to claims alleging the
unauthorized use of a third-party’s code in our products. This may occur for a variety of reasons, including the
expansion of our product lines, such as our Datacenter and Cloud Solutions and our Online Services division
products, through product development and acquisitions; an increase in patent infringement litigation
commenced by non-practicing entities; the increase in the number of competitors in our industry segments and
the resulting increase in the number of related products and the overlap in the functionality of those products; and
the unauthorized use of a third-party’s code in our product development process. Companies and inventors are
more frequently seeking to patent software despite recent developments in the law that may discourage or
invalidate such patents. As a result, we could receive more patent infringement claims. Responding to any
infringement claim, regardless of its validity, could result in costly litigation costs, monetary damages or
injunctive relief or require us to obtain a license to intellectual property rights of those third parties. Licenses
may not be available on reasonable terms, on terms compatible with the protection of our proprietary rights, or at
all. In addition, attention to these claims could divert our management’s time and attention from developing our
business. If a successful claim is made against us and we fail to develop or license a substitute technology or
negotiate a suitable settlement arrangement, our business, results of operations, financial condition and cash
flows could be materially and adversely affected. In particular, a material adverse impact on our financial
statements could occur in the period in which the effect of an unfavorable final outcome becomes probable and
reasonably estimable.

Our use of “open source” software could negatively impact our ability to sell our products and subject us to
possible litigation.

The products or technologies acquired, licensed or developed by us may incorporate so-called “open source”

software, and we may incorporate open source software into other products in the future. Such open source
software is generally licensed by its authors or other third parties under open source licenses, including, for
example, the GNU General Public License, the GNU Lesser General Public License, “Apache-style” licenses,
“Berkeley Software Distribution,” “BSD-style” licenses, and other open source licenses. We monitor our use of
open source software in an effort to avoid subjecting our products to conditions we do not intend. Although we
believe that we have complied with our obligations under the various applicable licenses for open source
software that we use such that we have not triggered any of these conditions, there is little or no legal precedent
governing the interpretation of many of the terms of these types of licenses. As a result, the potential impact of
these terms on our business may result in unanticipated obligations regarding our products and technologies, such
as requirements that we offer our products that use the open source software for no cost, that we make available

27

source code for modifications or derivative works we create based upon, incorporating or using the open source
software, and/or that we license such modifications or derivative works under the terms of the particular open
source license.

If an author or other third party that distributes open source software were to allege that we had not
complied with the conditions of one or more of these licenses, we could be required to incur significant legal
expenses defending against such allegations. If our defenses were not successful, we could be subject to
significant damages, enjoined from the distribution of our products that contained the open source software, and
required to comply with the terms of the applicable license, which could disrupt the distribution and sale of some
of our products. In addition, if we combine our proprietary software with open source software in an unintended
manner, under some open source licenses we could be required to release the source code of our proprietary
software, which could substantially help our competitors develop products that are similar to or better than ours.

In addition to risks related to license requirements, usage of open source software can lead to greater risks

than use of third-party commercial software, as open source licensors generally do not provide warranties or
assurance of title or controls on the origin of the software.

If open source software programmers, many of whom we do not employ, do not continue to develop and
enhance the open source Xen hypervisor, we may be unable to develop new XenServer products, adequately
enhance our existing XenServer products or meet customer requirements for innovation, quality and price of
these Xen products.

We rely to a significant degree on an informal community of independent open source software

programmers to develop and enhance the Xen hypervisor. A relatively small group of software engineers, many
of whom are not employed by us, are primarily responsible for the development and evolution of the Xen
hypervisor, which is the heart of the XenServer virtualization product. If these programmers fail to adequately
further develop and enhance open source technologies, we would have to rely on other parties to develop and
enhance the Xen hypervisor or we would need to develop and enhance the Xen hypervisor with our own
resources. We cannot predict whether further developments and enhancements to these technologies would be
available from reliable alternative sources. In either event, our development expenses could be increased and our
product release and upgrade schedules could be delayed. Moreover, if third-party software programmers fail to
adequately further develop and enhance the Xen hypervisor, the development and adoption of this virtual server
technology could be stifled and our products, including XenServer, could become less competitive. Delays in
developing, completing or shipping new or enhanced products could result in delayed or reduced revenue for
those products and could also adversely affect customer acceptance of those offerings.

Our inability to maintain or develop our strategic and technology relationships could adversely affect our
business.

Our business depends on strategic and technology relationships. We cannot assure you that those

relationships will continue in the future. We rely on strategic or technology relationships with companies such as
Microsoft, Intel, Dell, Hewlett-Packard Company, Fujitsu Limited and others. We depend on the entities with
which we have strategic or technology relationships to successfully test our products, to incorporate our
technology into their products and to market and sell those products. We cannot assure you that we will be able
to maintain our current strategic and technology relationships or to develop additional strategic and technology
relationships. If the companies with which we have strategic or technology relationships are unable to
incorporate our technology into their products or to market or sell those products, our business, results of
operations and financial condition could be materially adversely affected.

If we lose access to third-party licenses, releases of our products could be delayed.

We believe that we will continue to rely, in part, on third-party licenses to enhance and differentiate our

products. Third-party licensing arrangements are subject to a number of risks and uncertainties, including:

•

undetected errors or unauthorized use of another person’s code in the third party’s software;

28

•

•

•

disagreement over the scope of the license and other key terms, such as royalties payable;

infringement actions brought by third-party licensees; and

termination or expiration of the license.

If we lose or are unable to maintain any of these third-party licenses or are required to modify software
obtained under third-party licenses, it could delay the release of our products. Any delays could have a material
adverse effect on our business, results of operations and financial condition.

Our success depends on our ability to attract and retain and further penetrate large enterprise customers.

We must retain and continue to expand our ability to reach and penetrate large enterprise customers by
adding effective VADs and expanding our consulting services. Our inability to attract and retain large enterprise
customers could have a material adverse effect on our business, results of operations and financial condition.
Large enterprise customers usually request special pricing and purchase of multiple years of subscription and
maintenance up-front and generally have longer sales cycles, which could negatively impact our revenues. By
allowing these customers to purchase multiple years of subscription or maintenance up-front and by granting
special pricing, such as bundled pricing or discounts, to these large customers, we may have to defer recognition
of some or all of the revenue from such sales. This deferral could reduce our revenues and operating profits for a
given reporting period. Additionally, as we attempt to attract and penetrate large enterprise customers, we may
need to increase corporate branding and marketing activities, which could increase our operating expenses. These
efforts may not proportionally increase our operating revenues and could reduce our profits.

We rely on indirect distribution channels and major distributors that we do not control.

We rely significantly on independent distributors and resellers to market and distribute our products and
appliances. For instance, one distributor, Ingram Micro, accounted for 17% of our net revenues in 2010. Our
distributor arrangements with Ingram Micro consist of several non-exclusive, independently negotiated
agreements with our subsidiaries, each of which cover different countries or regions. Moreover, no reseller
accounted for over 10% of our total net revenues in 2010. We do not control our distributors and resellers.
Additionally, our distributors and resellers are not obligated to buy our products and could also represent other
lines of products. We maintain and periodically revise our sales incentive programs for our independent
distributors and resellers, and such program revisions may adversely impact our results of operations. Some of
our distributors and resellers maintain inventories of our packaged products for resale to smaller end-users. If
distributors and resellers reduce their inventory of our packaged products, our business could be adversely
affected. Further, we could maintain individually significant accounts receivable balances with certain
distributors. The financial condition of our distributors could deteriorate and distributors could significantly delay
or default on their payment obligations. Any significant delays, defaults or terminations could have a material
adverse effect on our business, results of operations and financial condition.

For certain of our products we rely on third-party suppliers and contract manufacturers, making us
vulnerable to supply problems and price fluctuations.

We rely on a number of third-party suppliers, who provide hardware or hardware components for our
products, and contract manufacturers. For example, the production, final test, warehousing and shipping for our
Datacenter and Cloud Solutions, including our NetScaler products, Access Gateway products and Citrix Repeater
appliance products, are primarily performed by a third-party contract manufacturer. We do not typically have
long-term supply agreements with our suppliers; and, in most cases, we purchase the products and components
on an as-needed purchase order basis. In some instances, such as with respect to our application networking
products in our Datacenter and Cloud Solutions portfolio, we maintain internal manufacturing capabilities to
supplement third-party contract manufacturers and provide us with the flexibility needed to meet our product
delivery requirements on sales orders on a limited basis. While we have not, to date, experienced any material
difficulties or delays in the manufacture and assembly of our products, our suppliers may encounter problems

29

during manufacturing due to a variety of reasons, including failure to follow specific protocols and procedures,
failure to comply with applicable regulations, equipment malfunction and environmental factors, any of which
could delay or impede their ability to meet our demand. Our reliance on these third-party suppliers and contract
manufacturers subjects us to risks that could harm our business, including:

•

•

•

our suppliers, especially new suppliers, may make errors in manufacturing components that could
negatively affect the efficacy of our products or cause delays in shipment;

our suppliers manufacture products for a range of customers, and fluctuations in demand for the
products these suppliers manufacture for others may affect their ability to deliver components and
products to us in a timely manner; and

our suppliers may encounter financial hardships unrelated to our demand for components, which could
inhibit their ability to fulfill our orders and meet our requirements.

There may be delays associated with establishing additional or replacement suppliers, particularly for
components that are available only from limited sources. Any interruption or delay in the supply of products or
components, or our inability to obtain products or components from alternate sources at acceptable prices in a
timely manner, could impair our ability to meet the demand of our customers and adversely affect our business,
financial condition or results of operations.

Our products could contain errors that could delay the release of new products and may not be detected until
after our products are shipped.

Despite significant testing by us and by current and potential customers, our products, especially new
products or releases or acquired products, could contain errors. In some cases, these errors may not be discovered
until after commercial shipments have been made. Errors in our products could delay the development or release
of new products and could adversely affect market acceptance of our products. Additionally, our products depend
on third- party products, which could contain defects and could reduce the performance of our products or render
them useless. Because our products are often used in mission-critical applications, errors in our products or the
products of third parties upon which our products rely could give rise to warranty or other claims by our
customers, which may have a material adverse effect on our business, financial condition and results of
operations.

We may experience outages, data loss and disruptions of our Online Services division’s services.

The increasing user traffic and complexity of our Online Services division demands more computing power.

We have spent and expect to continue to spend substantial amounts to adequately resource our Online Services
division’s data centers and to upgrade our technology and network infrastructure to handle the increased traffic of
our Collaboration, IT Services, and Access and Cloud services, including GoToMeeting, GoToAssist and
GoToMyPC, and to introduce new services. Maintaining and expanding this infrastructure’s capacity and
geographic footprint is expensive and complex. Inefficiencies or operational failures, including temporary service
outages and temporary or permanent loss of customer data, could diminish the perceived quality and reliability of
our services, and result in liability claims by customers and other third parties, damage to our reputation and loss
of current and potential subscribers, any of which could significantly and adversely affect our financial condition
and the operating results of our Online Services division.

If our security measures are breached and unauthorized access is obtained to our Online Services division
customers’ data, our services may be perceived as not being secure and customers may curtail or stop using
our service.

Use of our Collaboration, IT Services, and Access and Cloud services involves the storage and transmission
of customers’ business and personally identifiable information, and security breaches could expose us to a risk of
loss of this information, litigation and possible liability. If our security measures are breached as a result of

30

third-party action, employee error, malfeasance or otherwise, and, as a result, someone obtains unauthorized
access to one of our online customers’ personally identifiable data, our reputation will be damaged, our business
may suffer and we could incur significant liability. Because techniques used to obtain unauthorized access to or
sabotage systems change frequently and generally are not recognized until launched against a target, we may be
unable to anticipate these techniques or to implement adequate preventative measures. If any compromises of
security were to occur, it could have the effect of substantially reducing the use of the Web for commerce and
communications. Anyone who circumvents our security measures could misappropriate credit card and other
payment information, personally identifiable customer information or cause interruptions in our services or
operations. Fines and liabilities can be significant for breaches of payment card data. In the case of an actual
breach of payment card data, we could incur potential fines at the discretion of the credit card companies. These
fines could include penalties for all compromised account numbers, the costs of any additional fraud detection
activities required by the card associations, costs incurred by credit card issuers associated with the compromise
and additional monitoring of systems for further fraudulent activity. A large breach of payment card data could
also put our ability to process credit card payments at risk. Computer viruses, software programs that disable or
impair computers, have been and continue to be distributed and have rapidly spread over the Internet. Computer
viruses could be introduced into our systems or those of our vendors, which could disrupt our network or make it
inaccessible to our Online Services division customers. If an actual or perceived breach of our security occurs,
the market perception of the effectiveness of our security measures could be harmed and we could lose sales and
customers for our Online Services division, and in the case of an actual breach we could incur fines and other
penalties under privacy and data protection laws, which would significantly and adversely affect our financial
condition and the operating results of our Online Services division.

Evolving regulation of the Web may adversely affect our Online Services division.

As Web commerce continues to evolve, increasing regulation by federal, state or foreign agencies becomes

more likely. For example, we believe increased regulation is likely in the area of laws and regulations applying to
the solicitation, collection, processing or use of personal or consumer information. Additional regulation could
impact our business through increased costs and restrictions on our ability to process and secure customer data.
In addition, taxation of services provided over the Web or other charges imposed by government agencies or by
private organizations for accessing the Web may also be imposed. Any regulation imposing greater fees for Web
use or restricting information exchange over the Web could result in a decline in the use of the Web and the
viability of Web-based services, which would significantly adversely affect our financial condition and the
operating results for our Online Services division.

Regulation of audio services may adversely affect our Online Services division.

In October 2008, our Online Services division acquired Vapps, Inc., or Vapps, a VoIP-based audio services

company, to form our Citrix Online Audio products and services. Certain of these products and services are
subject to various regulatory requirements established by the Federal Communications Commission, or FCC.
FCC regulation may delay or hinder our ability to develop our services and products. The telecommunications
industry is highly regulated in the U.S. at the federal, state and local levels. Various state and international
authorities may also seek to regulate the products and services we provide or will provide. The FCC and state
regulatory authorities may address regulatory non-compliance with a variety of enforcement mechanisms,
including fines, refund orders, injunctive relief, license conditions, and/or license revocation. The regulation of
the telecommunications industry is changing rapidly, and the regulatory environment varies substantially from
jurisdiction to jurisdiction. There can be no assurance that future regulatory, judicial or legislative activities will
not have a material adverse effect on the business, and results of operations of our Online Services division.

Natural disasters or other unanticipated catastrophes that result in a disruption of our operations could
negatively impact our results of operations.

Our worldwide operations are dependent on our network infrastructure, internal technology systems and
website. Significant portions of our computer equipment, intellectual property resources and personnel, including
critical resources dedicated to research and development and administrative support functions are presently located

31

at our corporate headquarters in Fort Lauderdale, Florida, an area of the country that is particularly prone to
hurricanes, and at our various locations in California, an area of the country that is particularly prone to earthquakes.
We also have operations in various domestic and international locations that expose us to additional diverse risks.
The occurrence of natural disasters, such as hurricanes or earthquakes, or other unanticipated catastrophes, such as
telecommunications failures, cyber-attacks, fires or terrorist attacks, at any of the locations in which we do business,
could cause interruptions in our operations. For example, hurricanes have passed through southern Florida causing
extensive damage to the region. In addition, even in the absence of direct damage to our operations, large disasters,
terrorist attacks or other casualty events could have a significant impact on our partners’ and customers’ businesses,
which in turn could result in a negative impact on our results of operations. Extensive or multiple disruptions in our
operations, or our partners’ or customers’ businesses, due to natural disasters or other unanticipated catastrophes
could have a material adverse effect on our results of operations.

If we do not generate sufficient cash flow from operations in the future, we may not be able to fund our
product development and acquisitions and fulfill our future obligations.

Our ability to generate sufficient cash flow from operations to fund our operations and product
development, including the payment of cash consideration in acquisitions and the payment of our other
obligations, depends on a range of economic, competitive and business factors, many of which are outside our
control. We cannot assure you that our business will generate sufficient cash flow from operations, or that we
will be able to liquidate our investments, repatriate cash and investments held in our overseas subsidiaries, sell
assets or raise equity or debt financings when needed or desirable. An inability to fund our operations or fulfill
outstanding obligations could have a material adverse effect on our business, financial condition and results of
operations. For further information, please refer to “Management’s Discussion and Analysis of Financial
Condition and Results of Operations—Liquidity and Capital Resources.”

We have entered into a credit facility agreement that restricts our ability to conduct our business and failure to
comply with such agreement may have an adverse effect on our business, liquidity and financial position.

We, along with our subsidiary, Citrix Systems International GmbH, maintain a credit facility agreement that

contains financial covenants tied to a maximum consolidated leverage ratio and minimum interest coverage,
among other things. The credit facility agreement also contains affirmative and negative covenants, including
limitations related to our ability to incur future indebtedness, contingent obligations or liens, conduct certain
mergers or acquisitions, make certain investments and loans, alter our capital structure, sell stock or assets and
pay dividends. If we fail to comply with these covenants or any other provision of the credit facility agreement,
we may be in default under the credit facility agreement, and we cannot assure you that we will be able to obtain
the necessary waivers or amendments of such default. Upon an event of default under our credit facility
agreement not otherwise amended or waived, the affected lenders could accelerate the repayment of any
outstanding principal and accrued interest on their outstanding loans and terminate their commitments to lend
additional funds, which may have a material adverse effect on our liquidity and financial position.

Our stock price could be volatile, particularly during times of economic uncertainty and volatility in domestic
and international stock markets, and you could lose the value of your investment.

Our stock price has been volatile and has fluctuated significantly in the past. The trading price of our stock is

likely to continue to be volatile and subject to fluctuations in the future. Your investment in our stock could lose
some or all of its value. Some of the factors that could significantly affect the market price of our stock include:

•

•

•

•

actual or anticipated variations in operating and financial results;

analyst reports or recommendations;

changes in interest rates; and

other events or factors, many of which are beyond our control.

32

The stock market in general, The NASDAQ Global Select Market, and the market for software companies

and technology companies in particular, have experienced extreme price and volume fluctuations. These
fluctuations have often been unrelated or disproportionate to operating performance. These forces reached
unprecedented levels in the second half of 2008, resulting in the bankruptcy or acquisition of, or government
assistance to, several major domestic and international financial institutions and a material decline in economic
conditions. In particular, the U.S. equity markets experienced significant price and volume fluctuations that have
affected the market prices of equity securities of many technology companies. During 2010, our stock price has
experienced volatility, with the closing price of our common stock on The NASDAQ Global Select Market
having ranged from $41.15 on January 25, 2010 to $71.06 on September 28, 2010. These broad market and
industry factors could materially and adversely affect the market price of our stock, regardless of our actual
operating performance.

Changes or modifications in financial accounting standards may have a material adverse impact on our
reported results of operations or financial condition.

From time to time, the Financial Accounting Standards Board, or FASB, either alone or jointly with the

International Accounting Standards Board, IASB, promulgates new accounting principles that could have a
material adverse impact on our reported results of operations or financial condition. For example, in December
2007, the FASB issued authoritative guidance on business combinations. The guidance requires, among other
things, the expensing of direct transaction costs, including deal costs and restructuring costs as incurred and
acquired in-process research and development, or IPR&D, assets to be capitalized, certain contingent assets and
liabilities to be recognized at fair value, and arrangements related to contingent merger consideration may be
required to be measured at fair value until settled, with changes in fair value recognized each period into
earnings. Historically, we have been acquisitive; and if we continue to be so, the authoritative guidance could
have a material adverse impact on our consolidated financials, results of operations and cash flows if we enter
into any material business combinations.

In addition, it is likely that, in the near future, the United States will adopt International Financial Reporting

Standards, IFRS, issued by the IASB. Future accounting standards that we are required to adopt will change the
current accounting treatment that we apply to our financial statements. It is possible that such changes may have
a material adverse effect on our reported results of operations or financial condition.

Our business is subject to seasonal fluctuations that impact our quarterly results.

Our business is subject to seasonal fluctuations. Historically, our net revenues have fluctuated quarterly and

have generally been the highest in the fourth quarter of our fiscal year due to corporate calendar year-end
spending trends. In addition, our European operations generally provide lower revenues in the summer months
because of the generally reduced level of economic activity in Europe during the summer. This seasonal factor
also typically results in higher fourth quarter revenues. Quarterly results are also affected by the timing of the
release of new products and services. Because of the seasonality of our business, results for any quarter,
especially our fourth quarter, are not necessarily indicative of the results that may be achieved for the full fiscal
year.

ITEM 1B. UNRESOLVED STAFF COMMENTS

We have received no written comments regarding our periodic or current reports from the staff of the
Securities and Exchange Commission that were issued 180 days or more preceding the end of our 2010 fiscal
year that remain unresolved.

In addition our Enterprise division owns land and buildings in Fort Lauderdale, Florida with approximately
281,189 square feet of office space used for our corporate headquarter and 42,000 square feet of office space in
EMEA.

We believe that our existing facilities are adequate for our current needs. As additional space is needed in
the future, we believe that suitable space will be available in the required locations on commercially reasonable
terms.

ITEM 3. LEGAL PROCEEDINGS

Due to the nature of our business, we are subject to patent infringement claims, including current suits
against us or one or more of our wholly-owned subsidiaries alleging infringement by various Citrix products and
services. We believe that we have meritorious defenses to the allegations made in these pending suits and intend
to vigorously defend these lawsuits; however, we are unable currently to determine the ultimate outcome of these
or similar matters or the potential exposure to loss, if any.

In addition, we are a defendant in various litigation matters generally arising out of the normal course of
business. Although it is difficult to predict the ultimate outcomes of these cases, we believe that the ultimate
outcomes will not materially affect our business, financial position, results of operations or cash flows.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND

RESULTS OF OPERATIONS

Overview

We design, develop and market technology solutions that enable information technology, or IT, services to
be securely delivered on demand—independent of location, device or network. Our customers achieve lower IT
operating costs, increased information security, and greater business agility using Citrix technologies that enable
virtual computing. We market and license our products directly to enterprise customers, over the web, and
through systems integrators, or SIs, in addition to indirectly through value-added resellers, or VARs, value-added
distributors, or VADs, and original equipment manufacturers, or OEMs.

Executive Summary

Our solutions can fundamentally change an information technology organization’s approach and strategic

value, transforming IT into an on-demand service by centralizing the delivery of applications and desktops.
Further, this approach to IT transforms data centers, making them far more flexible to adapt to the changing
needs of an enterprise.

We believe our approach is unique in the market because we have combined innovative technologies in the

area of desktop management, including but not limited to desktop virtualization and application virtualization,
marketed as our Desktop Solutions, and server virtualization, application networking and optimization, marketed
as our Datacenter and Cloud Solutions, to deliver a comprehensive end-to-end application delivery solution, and
one that, when considered as a whole, is competitively differentiated by its feature set and interoperability.

The global recession that started in 2008 impacted IT spending, and we saw uncertainties surrounding IT

spending, particularly in the European markets in 2010. We expect this trend to continue as we enter 2011. The
overall economic uncertainty may adversely affect sales of our products and services and may result in longer
sales cycles, slower adoption of technologies and increased price competition, particularly in European markets.

In today’s business environment, however, there is a sharp focus on IT products and services that can reduce

cost and deliver a quick, tangible return on investment, or ROI. With our customers focused on economic value
in technology solutions, we intend to continue highlighting our solutions’ abilities to reduce IT costs, increase
business flexibility and deliver ROI.

Our Desktop Solutions are built to transform and reduce the cost of traditional desktop management by
virtualizing the desktop, with our XenDesktop product, and virtualizing applications, with our XenApp product,
in a customer’s datacenter, where they are more easily and efficiently maintained. We plan to continue the
initiatives that we began in the fourth quarter of 2009 and executed on throughout 2010 to accelerate our XenApp
install base’s adoption of our broader Desktop Solutions product portfolio through our XenDesktop trade-up
program.

Our Datacenter and Cloud Solutions, which include XenServer and NetScaler, can alter the traditional
economies of the datacenter by providing much greater levels of flexibility of computing resources, especially
with respect to servers, by improving application performance and thereby reducing the amount of processing
power involved, and allowing easy reconfiguration of servers for multiple purposes.

Our Online Services division is focused on developing and marketing Web-based access, support and
collaboration services. These services are primarily marketed via the Web to large enterprises, medium and small
businesses, prosumers and individuals. Our Online Services division’s web collaboration services offer secure
and cost-effective solutions that allow users to host and actively participate in online meetings, webinars and
training sessions remotely and reduce costs associated with business travel. Our remote access solution offers a
secure, simple and cost efficient way for users to access their desktops remotely, and our remote support
solutions offer secure, on-demand support over the Internet.

37

In addition, we expect to continue to grow our Online Services division by increasing our addressable

market geographically and offering services that appeal to a wider range of customers. To accelerate the
European expansion of our Online Services division, in February 2011, we acquired Netviewer AG, or
Netviewer, a privately held European SaaS vendor in collaboration and IT services. Netviewer will become part
of our Online Services division and enable the extension of our SaaS leadership in Europe.

Our priorities for 2011 are to sustain the long-term growth of our businesses and enhance our current
solutions through technological innovation, engineering excellence, selective and strategic acquisition of
technology, talent and/or companies, and through a commitment to delivering high-quality products and services
to customers and partners.

We expect to continue our 2010 initiatives and make strategic investments in research and development of
existing and new products, and to invest in research and development of advanced and innovative technologies
for future application, including increasing research and development capacity and headcount. We believe that
delivering innovative and high-value solutions through our Enterprise division’s products and our Online
Services division’s services is the key to meeting customer and partner needs and achieving our future
growth.We also intend to continue making significant investments to expand our brand awareness in
virtualization, networking and cloud computing spaces. We also plan to increase sales, consulting and technical
services capacity and headcount to drive larger strategic customer engagements and more focus on SI
partnerships as well as investing in new channel programs that allow our partners to upgrade their capabilities in
desktop virtualization, which we currently believe is our largest area of opportunity.

On January 28, 2009, we announced the implementation of a strategic restructuring program, or the 2009
Strategic Restructuring Program. The 2009 Strategic Restructuring Program included reducing our headcount by
approximately 450 full-time positions. In the year ended December 31, 2009, we incurred a pre-tax charge of
$26.5 million related to employee severance and related costs and costs related to the consolidation of certain of
our facilities.

Summary of Results

For the year ended December 31, 2010 compared to the year ended December 31, 2009, we delivered the

following financial performance:

•

Product License revenue increased 14.9% to $619.5 million;

• License Updates revenue increased 12.8% to $682.2 million;

• Online Services revenue increased 17.0% to $360.6 million;

• Technical Services revenue increased 31.1% to $212.3 million;

• Operating income increased 79.5% to $320.7 million;

• Diluted earnings per share increased 41.0% to $1.46;

• Cash flow from operations increased 27.3% to $616.3 million;

• Cash and investment balances increased 39.6% to $1,685.7 million; and

• Deferred revenues increased 25.9% to $779.0 million.

The increase in our Product License revenue was primarily driven by increased sales of our Datacenter and
Cloud Solutions, led by our Application Networking products and increased sales of our Desktop Solutions, led
by our XenDesktop product and XenDesktop trade-up program. We currently expect our Product License
revenue to increase when comparing the first quarter of 2011 to the first quarter of 2010. The increase in License
Updates revenue was driven by sales of new licenses with Subscription Advantage. Our Online Services revenue

38

increased due to increased sales of our web collaboration services. The increase in Technical Services revenue
was primarily driven by increased sales of support and consulting services related to our Enterprise division’s
products. Our increase in operating income and diluted earnings per share was driven by our increased revenue as
well as operating leverage gained by managing our overall operating expenses. In addition, 2009 operating
margin also included $26.5 million of additional operating expenses related to our 2009 Strategic Restructuring
Program. We currently expect that total revenue will increase when comparing the first quarter of 2011 to the
first quarter of 2010, as well as when comparing the 2011 fiscal year to the 2010 fiscal year.

During 2010, we generated positive operating cash flows of $616.3 million. These cash flows related

primarily to net income of $276.4 million, adjusted for, among other things, non-cash charges including
depreciation and amortization of $138.2 million, stock-based compensation expense of $103.8 million and the
tax effect of stock-based compensation of $51.5 million. Also contributing to these cash inflows is an aggregate
increase in cash flow from our operating assets and liabilities of $144.8 million, net of the effects of acquisitions.
These operating cash inflows are partially offset by the excess benefit from the exercise of stock options of $60.2
million and $46.7 million related to a deferred income tax benefit.

The increase in cash and investments at December 31, 2010 as compared to December 31, 2009, was
primarily due to cash provided by our operating activities of $616.3 million and cash received from the issuance
of common stock under our employee stock-based compensation plans of $353.6 million, partially offset by
expenditures made on our stock repurchases of $433.7 million and purchases of property and equipment of $75.4
million. The increase in deferred revenues at December 31, 2010 compared to December 31, 2009 was primarily
due to increased sales and renewals of our Subscription Advantage product of $102.0 million and increased sales
of our support services of $50.3 million.

Our business is subject to seasonal fluctuations. Historically, our net revenues have fluctuated quarterly and

have generally been the highest in the fourth quarter of our fiscal year due to corporate calendar year-end
spending trends. This seasonal factor also typically results in net revenue during the fourth quarter of any year
being typically higher than the revenue for the first quarter of the subsequent year.

2010 Acquisitions

On September 7, 2010, we acquired all of the issued and outstanding securities of VMLogix Inc., or

VMLogix, a privately held corporation headquartered in Santa Clara, California. VMLogix is a provider of
virtualization management software for private and public cloud computing systems. The total consideration for
this transaction was approximately $13.2 million, comprised of approximately $10.4 million in cash and
approximately $2.8 million related to VMLogix liabilities settled in conjunction with the acquisition. The sources
of funds for this transaction consisted of available cash. We recorded approximately $7.7 million of goodwill,
which is not deductible for tax purposes, and acquired $10.6 million in assets including $7.5 million of
identifiable intangible assets, of which $6.2 million is related to product related intangible assets with a useful
life of 5.0 years and $1.3 million is related to other intangible assets with a useful life of 4.0 years. We assumed
liabilities of approximately $5.1 million in conjunction with the acquisition. In addition, we also assumed stock
options for which the vesting period reset fully upon the closing of the transaction. When these stock options
vest, they will be exercisable for up to 47,784 shares of our common stock. We have included the effect of this
transaction in our results of operations prospectively from the date of the acquisition, which effect was not
material to our consolidated results.

During the first quarter of 2010, we acquired two privately-held companies for a total cash consideration of
approximately $9.2 million. We recorded approximately $2.6 million of goodwill, which is not deductible for tax
purposes, and acquired $9.4 million in assets including $7.1 million of identifiable intangible assets, of which
$6.2 million is related to product related intangible assets with a weighted-average useful life of 5.0 years and
$0.9 million is related to other intangible assets with a weighted-average useful life of 2.0 years. In addition, we

39

assumed liabilities of approximately $2.8 million in conjunction with the acquisitions. We have included the
effects of these transactions in our results of operations prospectively from the respective dates of the
acquisitions, which were not material to our consolidated results.

2008 Acquisition

In October 2008, we acquired all of the issued and outstanding securities of Vapps, Inc., or Vapps, a
privately held corporation headquartered in Hoboken, New Jersey. Vapps offers high quality audio conferencing
solutions to small and medium sized businesses and enterprise and service provider markets that complement our
online services. The total consideration for this transaction was approximately $29.7 million in cash, including
$1.0 million in transaction costs. At the time of the acquisition, if certain financial and operational milestones are
achieved by the Vapps business, contingent consideration of up to approximately $4.4 million may be earned. As
of December 31, 2010, $1.9 million and $1.2 million was earned in 2010 and 2009, respectively. The sources of
funds for this transaction consisted of available cash and investments. In addition, we assumed unvested stock
options upon the closing of the transaction, which will become exercisable (upon vesting) for approximately
0.1 million shares of our common stock. In connection with the Vapps Acquisition, we allocated $21.8 million to
goodwill, $8.2 million to product related technologies and $2.6 million to other intangible assets. The goodwill
related to the Vapps acquisition was allocated to our Online Services division and is not deductible for tax
purposes.

Netviewer AG Acquisition

In December 2010, we entered into an agreement to acquire all of the issued and outstanding securities of
Netviewer AG, or Netviewer, a privately held European SaaS vendor in collaboration and IT services. Netviewer
will become part of our Online Services division and the acquisition will enable the extension of our SaaS
leadership in Europe. The acquisition closed in February 2011 and the total preliminary consideration for this
transaction was approximately $115.0 million and was payable in cash. In addition, in connection with the
acquisition we converted and assumed approximately 99,100 non-vested stock units. Transaction costs associated
with the acquisition are currently estimated at $2.5 million, of which we expensed $2.0 million in 2010 and are
included in general and administrative expense in the accompanying consolidated statements of income for the
year ended December 31, 2010.

In-process Research and Development for Acquisitions

The fair values used in determining the purchase price allocation for certain intangible assets for our
acquisitions were based on estimated discounted future cash flows, royalty rates and historical data, among other
information. Purchased in-process research and development, or IPR&D, of $1.1 million was expensed
immediately upon the closing of the acquisition of Vapps because it pertained to technology that was not
currently technologically feasible, meaning it had not reached the working model stage, did not contain all of the
major functions planned for the product, was not ready for initial customer testing and had no alternative future
use. The fair value assigned to IPR&D was determined using the income approach, which includes estimating the
revenue and expenses associated with a project’s sales cycle and by estimating the amount of after-tax cash flows
attributable to the projects. The future cash flows were discounted to present value utilizing an appropriate risk-
adjusted rate of return, which was 21%. The rate of return determination included a factor that takes into account
the uncertainty surrounding the successful development of the IPR&D.

In 2009, we adopted new accounting rules for acquisitions and future IPR&D will be capitalized. No

IPR&D was capitalized in 2010 and 2009.

Critical Accounting Policies and Estimates

Our discussion and analysis of financial condition and results of operations are based upon our consolidated

financial statements, which have been prepared in accordance with accounting principles generally accepted in

40

the United States. The preparation of these financial statements requires us to make estimates and judgments that
affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent
liabilities. We base these estimates on our historical experience and on various other assumptions that we believe
to be reasonable under the circumstances, and these estimates form the basis for our judgments concerning the
carrying values of assets and liabilities that are not readily apparent from other sources. We periodically evaluate
these estimates and judgments based on available information and experience. Actual results could differ from
our estimates under different assumptions and conditions. If actual results significantly differ from our estimates,
our financial condition and results of operations could be materially impacted.

We believe that the accounting policies described below are critical to understanding our business, results of

operations and financial condition because they involve more significant judgments and estimates used in the
preparation of our consolidated financial statements. An accounting policy is deemed to be critical if it requires
an accounting estimate to be made based on assumptions about matters that are highly uncertain at the time the
estimate is made, and if different estimates that could have been used, or changes in the accounting estimates that
are reasonably likely to occur periodically, could materially impact our consolidated financial statements. We
have discussed the development, selection and application of our critical accounting policies with the Audit
Committee of our Board of Directors and our independent auditors, and our Audit Committee has reviewed our
disclosure relating to our critical accounting policies and estimates in this “Management’s Discussion and
Analysis of Financial Condition and Results of Operations.”

Note 2 to our consolidated financial statements included in this Annual Report on Form 10-K for the year
ended December 31, 2010 describes the significant accounting policies and methods used in the preparation of
our Consolidated Financial Statements.

Revenue Recognition

The accounting related to revenue recognition in the software industry is complex and affected by

interpretations of the rules and an understanding of industry practices, both of which are subject to change. As a
result, revenue recognition accounting rules require us to make significant judgments. In addition, our judgment
is required in assessing the probability of collection, which is generally based on evaluation of customer-specific
information, historical collection experience and economic market conditions. If market conditions continue to
decline, or if the financial condition of our distributors or customers deteriorates, we may be unable to determine
that collectability is probable, and we could be required to defer the recognition of revenue until we receive
customer payments.

We license most of our software products bundled with a one year contract for license updates that provide

the end-user with enhancements and unspecified upgrades to the licensed product on a when and if available
basis. Customers may also elect to purchase subscriptions for license updates, when not bundled with the initial
product license. Customers may also elect to purchase maintenance, technical support, product training or
consulting services. We allocate revenue to license updates, maintenance and any other undelivered elements of
the arrangement based on vendor specific objective evidence, or VSOE, of fair value of each element and such
amounts are deferred until the applicable delivery criteria and other revenue recognition criteria have been met.
The balance of the revenue, net of any discounts inherent in the arrangement, is recognized at the outset of the
arrangement using the residual method as the product licenses are delivered. If we cannot objectively determine
the fair value of each undelivered element based on the VSOE of fair value, we defer revenue recognition until
all elements are delivered or services have been performed, or until fair value can be objectively determined. We
must apply judgment in determining all elements of the arrangement and in determining the VSOE of fair value
for each element, considering the price charged for each product on a stand-alone basis or applicable renewal
rates for subscriptions related to new products.

In the normal course of business, we are not obligated to accept product returns from our distributors under

any conditions, unless the product item is defective in manufacture. We establish provisions for estimated

41

returns, as well as other sales allowances, concurrently with the recognition of revenue. The provisions are
established based upon consideration of a variety of factors, including, among other things, recent and historical
return rates for both, specific products and distributors, and the impact of any new product releases and projected
economic conditions. Our ability to recognize revenue upon shipment to our distributors is predicated on our
ability to reliably estimate returns. If actual experience or changes in market condition impairs our ability to
estimate returns, we would be required to defer the recognition of revenue until the delivery of the product to the
end-user. Product returns are provided for in the consolidated financial statements and have historically been
within our expectations. Allowances for estimated product returns amounted to approximately $0.9 million at
December 31, 2010 and $1.6 million at December 31, 2009. We also record estimated reductions to revenue for
customer programs and incentive offerings including volume-based incentives, at the time the sale is recorded.
We could take actions to increase our customer incentive offerings, which could result in an incremental
reduction to our revenue at the time the incentive is offered.

Stock-Based Compensation

Under the fair value recognition provisions of the authoritative guidance, stock-based compensation cost is

measured at the grant date based on the fair value of the award and is recognized as expense over the requisite
service or performance period, which is the vesting period. We currently use the Black-Scholes option pricing
model to determine the fair value of stock options. The determination of the fair value of stock-based payment
awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions
regarding a number of complex and subjective variables. These variables include our expected stock price
volatility over the term of the awards, the expected term of the award, the risk-free interest rate and any expected
dividends.

For purposes of determining the expected volatility factor, we used the implied volatility in two-year
market-traded options on our common stock based on third party volatility quotes in accordance with the
provisions of Staff Accounting Bulletin, or SAB, No. 107. Our decision to use implied volatility was based upon
the availability of actively traded options on our common stock and our assessment that implied volatility is more
representative of future stock price trends than historical volatility. The expected term of our options is based on
historical employee exercise patterns. We also analyzed our historical pattern of option exercises based on certain
demographic characteristics and we determined that there were no meaningful differences in option exercise
activity based on demographic characteristics. The approximate risk free interest rate is based on the implied
yield available on U.S. Treasury zero-coupon issues with remaining terms equivalent to the expected term on our
options. We do not intend to pay dividends on our common stock in the foreseeable future and, accordingly, we
used a dividend yield of zero in the option pricing model. We are required to estimate forfeitures at the time of
grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use
historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for
those awards that are expected to vest. All stock-based payment awards that vest based on service, including
those with graded vesting schedules, are amortized on a straight-line basis over the requisite service periods of
the awards, which are generally the vesting periods. We issue non-vested stock units with performance goals to
certain senior members of management. The number of non-vested stock units underlying each award may be
determined based on a range of attainment within defined performance goals. We are required to estimate the
attainment that will be achieved related to the defined performance goals and number of non-vested stock units
that will ultimately be awarded in order to recognize compensation expense over the vesting period. If our initial
estimates of performance goal attainment change, the related expense may fluctuate from quarter to quarter based
on those estimates and if the performance goals are not met, no compensation cost will be recognized and any
previously recognized compensation cost will be reversed. As of December 31, 2010, there was $102.2 million of
total unrecognized compensation cost related to options and non-vested stock units. That cost is expected to be
recognized over a weighted-average period of 2.20 years.

If factors change and we employ different assumptions for estimating stock-based compensation expense in

future periods or if we decide to use a different valuation model, the stock-based compensation expense we

42

recognize in future periods may differ significantly from what we have recorded in the current period and could
materially affect our operating income, net income and earnings per share. This may result in a lack of
consistency in future periods and materially affect the fair value estimate of stock-based payments. It may also
result in a lack of comparability with other companies that use different models, methods and assumptions. The
Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options that
have no vesting restrictions and are fully transferable. These characteristics are not present in our option grants.
Existing valuation models, including the Black-Scholes and lattice binomial models, may not provide reliable
measures of the fair values of our stock-based compensation. Consequently, there is a risk that our estimates of
the fair values of our stock-based compensation awards on the grant dates may bear little resemblance to the
actual values realized upon the exercise, expiration, early termination or forfeiture of those stock-based payments
in the future. Certain stock-based payments, such as employee stock options, may expire with little or no intrinsic
value compared to the fair values originally estimated on the grant date and reported in our financial statements.
Alternatively, the value realized from these instruments may be significantly higher than the fair values originally
estimated on the grant date and reported in our financial statements. There is currently no market-based
mechanism or other practical application to verify the reliability and accuracy of the estimates stemming from
these valuation models, nor is there a means to compare and adjust the estimates to actual values. See Notes 2
and 7 to our consolidated financial statements included in this Annual Report on Form 10-K for the year ended
December 31, 2010 for further information regarding our adoption of the authoritative guidance for stock-based
compensation.

Valuation and Classification of Investments

The authoritative guidance, which among other things, defines fair value as the price that would be received

to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the
measurement date (an exit price). Our investments are carried at fair value and in determining their fair value we
are sometimes required to use various alternative valuation techniques. The authoritative guidance establishes a
hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the
use of unobservable inputs by requiring that the most observable inputs be used when available.

The authoritative guidance establishes a three-tier fair value hierarchy, which prioritizes the inputs used in
measuring fair value as follows: the fair value hierarchy gives the highest priority to unadjusted quoted prices in
active markets for identical assets or liabilities, described as Level 1, and the lowest priority to valuation
techniques using unobservable inputs, described as Level 3. Observable inputs are those that market participants
would use in pricing the asset or liability that are based on market data obtained from independent sources, such
as market quoted prices. When Level 1 observable inputs for our investments are not available to determine their
fair value, we must then use other inputs which may include indicative pricing for securities from the same issuer
with similar terms or unobservable inputs that reflect our estimates of the assumptions market participants would
use in pricing the investments based on the best information available in the circumstances. When valuation
techniques, other than those described as Level 1 are utilized, management must make estimations and judgments
in determining the fair value for its investments. The degree to which management’s estimation and judgment is
required is generally dependent upon the market pricing available for the investments, the availability of
observable inputs, the frequency of trading in the investments and the investment’s complexity. If we make
different judgments regarding unobservable inputs we could potentially reach different conclusions regarding the
fair value of our investments.

After we have determined the fair value of our investments, for those that are in an unrealized loss position,

we must then determine if the investment is other-than-temporarily impaired. We review our investments
quarterly for indicators of other-than-temporary impairment. This determination requires significant judgment
and if different judgments are used the classification of the losses related to our investments could differ. In
making this judgment, we employ a systematic methodology that considers available quantitative and qualitative
evidence in evaluating potential impairment of our investments. If the amortized cost of an investment exceeds
its fair value, we evaluate, among other factors, general market conditions, the duration and extent to which the

43

fair value is less than amortized cost and our intent to retain or sell the investment and whether it is more likely
than not that we will not be required to sell the investment before the recovery of its amortized cost basis, which
may not be until maturity. We also consider specific adverse conditions related to the financial health of and
business outlook for the issuer, including industry and sector performance, rating agency actions and changes in
credit default swap levels. Once a decline in fair value is determined to be other-than-temporary, an impairment
charge is recorded and a new cost basis in the investment is established. See Notes 4 and 5 to our consolidated
financial statements and “Liquidity and Capital Resources” for more information on our investments and fair
value measurements.

Product Related Technology Assets

We have acquired product related technology assets from our business combinations and other third party
agreements. In applying purchase accounting, we allocate a portion of purchase price of acquired companies to
the product related technology assets acquired based on their estimated fair values. We typically engage third
party appraisal firms to assist us in determining the fair values and useful lives of product related technology
assets acquired. Such valuations and useful life determinations require us to make significant estimates and
assumptions. These estimates are based on historical experience and information obtained from the management
of the acquired companies and are inherently uncertain. Critical estimates in determining the fair value and useful
lives of the product related technology assets include but are not limited to future expected cash flows earned
from the product related technology and discount rates applied in determining the present value of those cash
flows. Unanticipated events and circumstances may occur which may affect the accuracy or validity of such
assumptions, estimates or actual results.

We review acquired product related technology assets for impairment on a periodic basis by comparing the
estimated net realizable value to the unamortized cost of the technology. The recoverability of these technologies
is primarily dependent upon our ability to commercialize products utilizing these technologies. The estimated net
realizable value of the purchased technology is based on the estimated undiscounted future cash flows derived
from such technology. Our assumptions about future revenues and expenses require significant judgment
associated with the forecast of the performance of our products. Actual revenues and costs could vary
significantly from these forecasted amounts. As of December 31, 2010, the estimated undiscounted future cash
flows expected from product related technology assets from these acquisitions is sufficient to recover their
carrying value. If these products are not ultimately accepted by our customers and distributors, and there is no
alternative future use for the technology, we could determine that some or all of their remaining $114.0 million
carrying value is impaired. In the event of impairment, we would record an impairment charge to earnings that
could have a material adverse effect on our results of operations.

Goodwill

At December 31, 2010, we had $921.1 million in goodwill related to our acquisitions. The goodwill
recorded in relation to these acquisitions is not deductible for tax purposes. Our revenues are derived from sales
of our Enterprise division products which include our Desktop Solutions, Datacenter and Cloud Solutions and
related technical services and from sales of our Online Services division’s web collaboration, remote access and
support services. The Enterprise division and the Online Services division constitute our two reportable
segments. See Note 12 to our consolidated financial statements included in this Annual Report on Form 10-K for
the year ended December 31, 2010 for additional information regarding our reportable segments. We evaluate
goodwill between these segments, which represent our reporting units.

We account for goodwill in accordance with FASB’s authoritative guidance which requires that goodwill
and certain intangible assets are not amortized, but are subject to an annual impairment test. We complete our
goodwill impairment test on an annual basis, during the fourth quarter of our fiscal year, or more frequently, if
changes in facts and circumstances indicate that an impairment in the value of goodwill recorded on our balance
sheet may exist. In order to estimate the fair value of goodwill, we typically estimate future revenue, consider

44

market factors and estimate our future cash flows. Based on these key assumptions, judgments and estimates, we
determine whether we need to record an impairment charge to reduce the value of the goodwill carried on our
balance sheet to its estimated fair value. Assumptions, judgments and estimates about future values are complex
and often subjective. They can be affected by a variety of factors, including external factors such as industry and
economic trends, and internal factors such as changes in our business strategy or our internal forecasts. Although
we believe the assumptions, judgments and estimates we have made in the past have been reasonable and
appropriate, different assumptions, judgments and estimates could materially affect our results of operations.

There was no impairment of goodwill as a result of the annual impairment tests completed during the fourth

quarters of 2010 and 2009. Excluding goodwill, we have no intangible assets deemed to have indefinite lives.

Income Taxes

We are required to estimate our income taxes in each of the jurisdictions in which we operate as part of the
process of preparing our consolidated financial statements. At December 31, 2010, we had approximately $130.0
million in net deferred tax assets. The authoritative guidance requires a valuation allowance to reduce the
deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some portion or
all of the deferred tax assets will not be realized. We review deferred tax assets periodically for recoverability
and make estimates and judgments regarding the expected geographic sources of taxable income and gains from
investments, as well as tax planning strategies in assessing the need for a valuation allowance. At December 31,
2010, we determined that a $14.0 million valuation allowance relating to deferred tax assets for net operating
losses was necessary. If the estimates and assumptions used in our determination change in the future, we could
be required to revise our estimates of the valuation allowances against our deferred tax assets and adjust our
provisions for additional income taxes.

In the ordinary course of global business, there are transactions for which the ultimate tax outcome is
uncertain, thus judgment is required in determining the worldwide provision for income taxes. We provide for
income taxes on transactions based on our estimate of the probable liability. We adjust our provision as
appropriate for changes that impact our underlying judgments. Changes that impact provision estimates include
such items as jurisdictional interpretations on tax filing positions based on the results of tax audits and general
tax authority rulings. Due to the evolving nature of tax rules combined with the large number of jurisdictions in
which we operate, it is possible that our estimates of our tax liability and the realizability of our deferred tax
assets could change in the future, which may result in additional tax liabilities and adversely affect our results of
operations, financial condition and cash flows.

The following discussion relating to the individual financial statement captions, our overall financial

performance, operations and financial position should be read in conjunction with the factors and events
described in “—Overview” and Part 1—Item 1A entitled “Risk Factors,” which could impact our future
performance and financial position.

Revenues

Net revenues of our Enterprise division include the following categories: Product Licenses, License Updates
and Technical Services. Product Licenses primarily represent fees related to the licensing of the following major
products:

• Our Desktop Solutions, comprised primarily of our desktop virtualization product XenDesktop and our

application virtualization product XenApp; and

• Our Datacenter and Cloud Solutions, comprised primarily of our application networking products

NetScaler, Access Gateway and Branch Repeater and our virtual infrastructure products, XenServer
and Essentials for Hyper-V.

In addition, we offer incentive programs to our VADs and VARs to stimulate demand for our products.

Product License revenues associated with these programs are partially offset by these incentives to our VADs
and VARs.

License Updates consist of fees related to our Subscription Advantage program that are recognized ratably

over the term of the contract, which is typically 12 to 24 months. Subscription Advantage is an annual renewable
program that provides subscribers with automatic delivery of unspecified software upgrades, enhancements and
maintenance releases when and if they become available during the term of the subscription. Technical Services
revenues are comprised of fees from technical support services which are recognized ratably over the contract
term, as well as revenues from product training and certification, and consulting services revenue related to
implementation of our products, which is recognized as the services are provided.

Our Online Services division’s revenues consist of fees related to online service agreements from our web

collaboration products which primarily include our GoToMeeting, GoToWebinar, Hi-Def Audio, and
GoToTraining services, our remote access, GoToMyPC, and our remote IT support which primarily include
GoToAssist and GoToManage. Our Online Services revenue is recognized ratably over the contract term.

Product Licenses

Product License revenue increased during 2010 when compared to 2009 primarily due to increased sales of

our Datacenter and Cloud Solutions, led by NetScaler,of $41.3 million and increased sales of our Desktop
Solutions, led by XenDesktop and related programs of $41.2 million. Product License revenue decreased during
2009 when compared to 2008 due to decreased sales of our Desktop Solutions, primarily XenApp, of $81.5
million. The decrease in XenApp sales in 2009 was driven primarily by weakness in the global economy. We
currently expect Product License sales to increase when comparing the first quarter of 2011 to the first quarter of
2010.

License Updates

License Updates revenue increased during 2010 when compared to 2009 primarily due to an increase in new

Subscription Advantage sales, led by increased XenDesktop product sales. License Updates revenue increased

47

during 2009 when compared to 2008 primarily due to renewals related to our Subscription Advantage program
over a larger base of subscribers. We currently anticipate that License Updates revenue will increase when
comparing the first quarter of 2011 to the first quarter of 2010 and when comparing the first quarter of 2011 to
the fourth quarter of 2010 due primarily to renewals of Subscription Advantage.

Online Services

Online Services revenue increased during 2010 when compared to 2009 and during 2009 compared to 2008

primarily due to increased sales of our web collaboration products. We currently expect our Online Services
revenue to increase when comparing the first quarter of 2011 to the first quarter of 2010 and when comparing the
first quarter of 2011 to the fourth quarter of 2010 due primarily to sales of our web collaboration products.

Technical Services

Technical Services revenue increased during 2010 when compared to 2009 primarily due to increases in

support revenues of $22.5 million driven by increased sales of our Datacenter and Cloud Solutions and an
increase in consulting revenues of $15.4 million related to increased sales of our Enterprise division’s products.
Technical Services revenue increased during 2009 when compared to 2008 primarily due to increased sales of
support services related to our Datacenter and Cloud Solutions. We currently expect Technical Services revenues
to increase when comparing the first quarter of 2011 to the first quarter of 2010 consistent with the increase in
Product License revenue described above.

Deferred Revenue

Deferred revenues are primarily comprised of License Updates revenue from Subscription Advantage,

Technical Services revenues related to our support services and consulting contracts and Online Services
revenues from annual service agreements for our Online Services. Deferred revenues increased approximately
$160.1 million as of December 31, 2010 compared to December 31, 2009 primarily due to increased sales and
renewals of our Subscription Advantage product of $102.0 million and increased sales of our support services of
$50.3 million. We currently expect deferred revenue to continue to increase in the first quarter of 2011.

While it is generally our practice to promptly ship our products upon receipt of properly finalized purchase

orders, we sometimes have product license orders that have not shipped. Although the amount of such product
license orders may vary, the amount, if any, of such product license orders at the end of a particular period has
not been material to total revenue at the end of any fiscal year. We do not believe that backlog, as of any
particular date, is a reliable indicator of future performance.

International Revenues

International revenues (sales outside the United States) accounted for approximately 42.7% of our net

revenues for the year ended December 31, 2010, 43.6% of our net revenues for the year ended December 31,
2009 and 45.8% for the year ended December 31, 2008. For detailed information on international revenues,
please refer to Note 12 to our consolidated financial statements included in this Annual Report on Form 10-K for
the year ended December 31, 2010.

Segment Revenues

During the first quarter of 2010, we changed how we measure profitability internally, develop our annual
plan and allocate our resources from a geography-based approach (which included the Americas; Europe, the
Middle East and Africa; Asia-Pacific and our Online Services division), to a product division-based approach.
This change reflects how we market and sell our products. Accordingly, we have revised our reportable segments
to reflect the way we are currently managing and viewing the business. Our revenues are derived from sales of
Enterprise division products which primarily include our Desktop Solutions, Datacenter and Cloud Solutions and
related technical services and from our Online Services division’s web collaboration, remote access and support
services. The Enterprise division and the Online Services division constitute our two reportable segments.

Cost of product license revenues consists primarily of hardware, product media and duplication, manuals,
packaging materials, shipping expense and royalties. Cost of services revenue consists primarily of compensation
and other personnel-related costs of providing technical support and consulting, as well as the costs related to
providing our online services. Also included in cost of net revenues is amortization of product related intangible
assets.

Cost of product license revenues increased during 2010 when compared to 2009 and during 2009 when
compared to 2008 primarily due to increased revenue of our Datacenter and Cloud products, many of which
contain hardware components that have a higher cost than our other software products. We currently anticipate
cost of product license revenues will increase when comparing the first quarter of 2011 to the first quarter of
2010 consistent with product license revenues.

Cost of services revenues increased during 2010 compared to 2009 consistent with the increase in revenue
of technical services related to our Enterprise products as described above. Cost of services revenues increased
$9.5 million during 2009 compared to 2008 primarily due to an increase in revenue of our Online Services. This
increase was partially offset by a decrease of $2.2 million during 2009 compared to 2008 due to decreased
revenue of our Desktop Solutions consulting and educational services, primarily related to lower XenApp
revenue. We currently anticipate cost of services revenues will increase when comparing the first quarter of 2011
to the first quarter of 2010 consistent with the increase in Online Services and Technical Services revenues as
discussed above.

Gross Margin

Gross margin as a percent of revenue was 88.1% for 2010, 88.4% for 2009 and 88.9% for 2008. The slight

decrease in gross margin as a percentage of net revenue for all periods presented was primarily due to the
increase in cost of net revenues as discussed above.

49

Operating Expenses

Foreign Currency Impact on Operating Expenses

A substantial majority of our overseas operating expenses and capital purchasing activities are transacted in
local currencies and are therefore subject to fluctuations in foreign currency exchange rates. In order to minimize
the impact on our operating results, we generally initiate our hedging of currency exchange risks up to 15 months
in advance of anticipated foreign currency expenses. When the dollar is weak, the resulting increase to foreign
currency denominated expenses will be partially offset by the gain in our hedging contracts. When the dollar is
strong, the resulting decrease to foreign currency denominated expenses will be partially offset by the loss in our
hedging contracts. There is a risk that there will be fluctuations in foreign currency exchange rates beyond the
one-year timeframe for which we hedge our risk.

Other Items Impacting Operating Expenses

Under our 2009 Strategic Restructuring Program, we reduced our headcount by approximately 450 full-time
positions and consolidated excess facilities. Due to the 2009 Strategic Restructuring Program, compensation and
employee related costs when comparing 2009 to 2008 decreased by approximately $21.6 million, net of costs
related to the 2009 Strategic Restructuring Program, across all functional areas including research and
development, sales, marketing and services and general and administrative expenses. These savings were
partially offset by strategic investments in the business during 2009. For more information regarding the 2009
Strategic Restructuring Program, see the Executive Summary above.

In addition, during the first quarter of 2009, we revised our methodology for allocating depreciation and

certain facilities-related costs to more closely align these allocated costs to the employees directly utilizing the
assets and facilities. In the fourth quarter of 2008, we recorded a reduction to operating expenses of
approximately $6.4 million related to an adjustment of payroll taxes initially recorded in conjunction with our
voluntary, independent investigation of our historical stock option granting practices which were reduced upon
agreement with the Internal Revenue Service.

Research and development expenses consisted primarily of personnel related costs and facility and

equipment costs directly related to our research and development activities. We expensed substantially all
development costs included in the research and development of our products.

Research and development expenses increased during 2010 as compared to 2009 primarily due to a $30.9

million increase in compensation and other employee related costs. Also contributing to the increase in research
and development expenses was a $10.9 million increase in facilities and related depreciation. These increases
primarily relate to the strategic hiring of headcount in research and development as discussed above in our
Executive Summary.

Research and development expenses decreased during 2009 as compared to 2008 primarily due to a $17.3

million decrease in compensation and other employee related costs due to the implementation of the 2009
Strategic Restructuring Program. Also contributing to the decrease in research and development expenses was an
$8.7 million decrease in stock-based compensation expense primarily related to vesting of awards assumed in
conjunction with our acquisition of XenSource. These decreases were partially offset by a $16.3 million increase

50

in depreciation and facility- related costs due primarily to the revised allocation methodology described above
and by a $5.2 million increase in compensation expense due to the adjustment of goodwill related to our
acquisition of XenSource.

Sales, marketing and services expenses consisted primarily of personnel-related costs, including sales

commissions, the costs of marketing programs aimed at increasing revenue, such as brand development,
advertising, trade shows, public relations and other market development programs and costs related to our
facilities, equipment and information systems that are directly related to our sales, marketing and services
activities.

Sales, marketing and services expenses increased during 2010 compared to 2009 primarily due to a $43.1
million increase in compensation including variable compensation and employee related costs due to additional
headcount in our sales force and technical services group. Also contributing to the increase in sales, marketing
and services expense was a $13.8 million increase in marketing program costs related to our brand awareness
campaigns.

Sales, marketing and services expenses increased during 2009 compared to 2008 primarily due to a $26.2

million increase in depreciation and other facility-related costs due primarily to the revised allocation
methodology described above. Also contributing to the increase in sales, marketing and services expenses was a
$7.4 million increase in marketing program costs related to our worldwide advertising campaigns, a $3.5 million
increase due to an increase in commissions paid to our resellers and a $3.0 million increase due to the settlement
of foreign currency contracts during the period which was offset by lower foreign currency denominated
expenses due to a stronger U.S. dollar. These increases were partially offset by a $34.5 million decrease in
compensation and other employee related costs resulting from the implementation of the 2009 Strategic
Restructuring Program. For more information see, “—Overview” included in this Annual Report on Form 10-K

General and administrative expenses consisted primarily of personnel related costs and expenses related to

outside consultants assisting with information systems, as well as accounting and legal fees. General and
administrative expenses increased during 2010 compared to 2009 primarily due to an increase in compensation
and employee related costs due to additional headcount, primarily in IT.

General and administrative expenses decreased during 2009 compared to 2008 primarily due to a $26.7
million decrease resulting from the revised methodology of allocating depreciation and other facility related costs
as described above (net of current period additions). These decreases were partially offset by an increase in legal
fees of $8.7 million.

2011 Operating Expense Outlook

When comparing the first quarter of 2011 to the first quarter of 2010 we expect operating expenses to
increase across all functional areas, including research and development, sales, marketing and services and
general and administrative due to the investments that we have made in headcount and related expenses during
2010. When comparing the fourth quarter of 2010 to the first quarter of 2011, we expect operating expenses to
remain relatively constant.

Amortization of other intangible assets consists of amortization of customer relationships, trade names and

assets during 2010 as compared to 2009 was primarily due to acquired customer related intangible assets
becoming fully amortized during 2010. The decrease in amortization of other intangible assets during 2009 as
compared to 2008 was not significant. As of December 31, 2010, we had unamortized other identified intangible
assets with estimable useful lives in the net amount of $64.2 million. For more information regarding our
acquisitions see, “—Overview” and Note 3 to our consolidated financial statements included in this Annual
Report on Form 10-K for the year ended December 31, 2010.

On January 28, 2009, we announced the implementation of the 2009 Strategic Restructuring Program, which

primarily included the reduction of our headcount by approximately 450 full-time positions. During 2009, we
incurred a pre-tax charge of $26.5 million of which $21.7 million related to severance and other costs directly
related to the reduction of our workforce and $4.8 million related to the consolidation of certain of our facilities.
The restructuring program was substantially completed by the end of 2009. For more information see,

The decrease in interest income during 2010 as compared to 2009 was primarily due to lower average

interest rates partially offset by higher overall average cash and investment balances during the year. Interest
income decreased during 2009 as compared to 2008 primarily due to lower interest rates earned on cash
equivalents and investment balances. For more information see “—Overview” and “—Liquidity and Capital

Other (expense) income, net is primarily comprised of remeasurement of foreign currency transaction gains

(losses) and realized gains (losses) related to changes in the fair value of our investments that have a decline in
fair value that is considered other-than-temporary, if any, and recognized gains (losses) related to
available-for-sale investments.

Other (expense) income, net increased when comparing 2010 to 2009 primarily due to losses recognized on
prepayments at par of securities purchased at a premium within our available-for-sale investment portfolio. Other
(expense) income, net decreased when comparing 2009 to 2008 primarily due to foreign exchange gains related
to financial statement remeasurement of $10.1 million and a decrease in losses on investments that were
determined to have an other-than-temporary decline in value of $1.5 million. These decreases in other (expense)
income were partially offset by an increase in losses related to our foreign currency transactions of $5.7 million.
For more information see “—Liquidity and Capital Resources” and Note 4 to our consolidated financial
statements included in this Annual Report on Form 10-K for the year ended December 31, 2010.

Income Taxes

We and certain of our subsidiaries are subject to federal income taxes in the U.S. as well as income taxes of
multiple state and foreign jurisdictions. With few exceptions, we are no longer subject to U.S. federal, state and
local, or non-U.S. income tax examinations by tax authorities for years prior to 2004.

In 2010, our effective tax rate increased to approximately 19.1% from (8.6)% when comparing the three
months ended December 31, 2010 to the three months ended December 31, 2009 primarily due to a larger benefit
from higher tax credits recognized in the fourth quarter of 2009. When comparing the twelve months ended
December 31, 2010 to the twelve months ended December 31, 2009, our effective tax rate increased to 17.2%
from 1.5% primarily due to a larger benefit from higher tax credits recognized in 2009 and to a lesser extent
higher income in geographic locations taxed at a higher rate.

We establish tax reserves when, despite our belief that our tax return positions are fully supportable, certain

of these positions may be challenged. While it is often difficult to predict whether we will prevail, we believe
that our tax reserves reflect the probable outcome of known contingencies. As such, included in our effective tax
rate for the year ended December 31, 2010 is an additional tax reserve of approximately $18.9 million related to
uncertainties arising from current and prior tax years partially offset by a reduction of approximately $1.2 million
in tax reserves related to the expiration of a statute of limitations for the 2006 tax year.

As of December 31, 2010, our liabilities related to uncertain tax positions totaled approximately $63.9
million. There was $1.5 million included in the balance at December 31, 2010 for tax positions, which would not
affect the annual effective tax rate and approximately $1.3 million of accrued interest on tax positions, which is
included in income tax expense.

We are subject to the continuous examination of our income tax returns by tax authorities. We regularly
assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our
provision for income taxes. There can be no assurance, however, that the outcomes from these continuous
examinations will not have an adverse effect on our effective tax rate.

In the ordinary course of global business, there are transactions for which the ultimate tax outcome is
uncertain and judgment is required in determining the worldwide provision for income taxes. We provide for

53

income taxes on transactions based on our estimate of the probable liability. We adjust our provision as
appropriate for changes that impact our underlying judgments. Changes that impact provision estimates include
such items as jurisdictional interpretations on tax filing positions based on the results of tax audits and general
tax authority rulings. Due to the evolving nature of tax rules combined with the large number of jurisdictions in
which we operate, it is possible that our estimates of our tax liability and the realizability of our deferred tax
assets could change in the future, which may result in additional tax liabilities and adversely affect our results of
operations, financial condition and cash flows. In June 2010, we reached a settlement in principle with the IRS
regarding certain previously disclosed income tax deficiencies asserted in a Revenue Agent’s Report, or RAR.
Under the terms of the settlement in principle, we would agree to an assessment of income tax deficiencies in full
settlement of all open claims under the RAR and would resolve with finality for future years all of the transfer
pricing issues raised in the RAR. Based on this, we incurred a charge of $13.1 million in 2010 in accordance with
the authoritative guidance. Among other things, the authoritative guidance requires application of a “more likely
than not” threshold to the recognition and non-recognition of tax positions. It further requires that a change in
management judgment related to prior years’ tax positions be recognized in the quarter of such change.

The final settlement requires the finalization of tax deficiency calculations with the IRS and a written
agreement signed by the IRS. It is uncertain how long it will take to reach a final settlement with the IRS. There
can be no assurances that a final written agreement will be obtained or that this matter will otherwise be resolved
in our favor. An adverse outcome of this matter could have a material adverse effect on our results of operations
and financial condition. We are required to estimate our income taxes in each of the jurisdictions in which we
operate as part of the process of preparing our consolidated financial statements. At December 31, 2010, we had
approximately $130.0 million in net deferred tax assets. The authoritative guidance requires a valuation
allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than
not that some portion or all of the deferred tax assets will not be realized. We review deferred tax assets
periodically for recoverability and make estimates and judgments regarding the expected geographic sources of
taxable income and gains from investments, as well as tax planning strategies in assessing the need for a
valuation allowance. At December 31, 2010, we determined that $14.0 million valuation allowance relating to
deferred tax assets for net operating losses and tax credits was necessary. If the estimates and assumptions used
in our determination change in the future, we could be required to revise our estimates of the valuation
allowances against our deferred tax assets and adjust our provisions for additional income taxes.

We maintain certain operational and administrative processes in overseas subsidiaries and its foreign
earnings are taxed at lower foreign tax rates. We do not expect to remit earnings from our foreign subsidiaries.

Liquidity and Capital Resources

During 2010, we generated positive operating cash flows of $616.3 million. These cash flows related

primarily to net income of $276.4 million, adjusted for, among other things, non-cash charges including
depreciation and amortization of $138.2 million, stock-based compensation expense of $103.8 million and the
tax effect of stock-based compensation of $51.5 million. Also contributing to these cash inflows is an aggregate
increase in cash flow from our operating assets and liabilities of $144.8 million, net of the effects of acquisitions.
These operating cash inflows are partially offset by the excess benefit from the exercise of stock options of $60.2
million and $46.7 million related to a deferred income tax benefit. Our investing activities used $457.0 million of
cash consisting primarily of cash paid for net purchases of investments of $335.0 million. Also contributing to
these cash outflows is the purchase of property and equipment of $75.4 million and $46.7 million in cash paid for
licensing agreements, acquisitions and other assets. Our financing activities used cash of $26.3 million, primarily
from expenditures on our stock repurchase program of $433.7 million partially offset by proceeds received from
the issuance of common stock under our employee stock-based compensation plans of $353.6 million and the
excess tax benefit from the exercise of stock options of $60.2 million.

During 2009, we generated positive operating cash flows of $484.0 million. These cash flows related

primarily to net income of $191.0 million, adjusted for, among other things, non-cash charges including

54

depreciation and amortization of $138.6 million, stock-based compensation expense of $111.4 million and a
goodwill adjustment of $5.4 million. Also contributing to these cash inflows is an aggregate increase in cash flow
from our operating assets and liabilities of $87.6 million, net of the effects of acquisitions. These operating cash
inflows are partially offset by $50.8 million related to a deferred income tax benefit, the tax effect of stock-based
compensation of $7.9 million and the excess benefit from the exercise of stock options of $5.2 million. Our
investing activities used $502.9 million of cash consisting primarily of cash paid for net purchases of investments
of $412.7 million. Also contributing to these cash outflows is the purchase of property and equipment of $76.2
million. Our financing activities used cash of $45.5 million, primarily from expenditures on our stock repurchase
program of $214.9 million partially offset by proceeds received from the issuance of common stock under our
employee stock-based compensation plans of $166.0 million.

Historically, significant portions of our cash inflows were generated by our operations. We currently expect

this trend to continue throughout 2011. We believe that our existing cash and investments together with cash
flows expected from operations will be sufficient to meet expected operating and capital expenditure
requirements for the next 12 months. We continue to search for suitable acquisition candidates and could acquire
or make investments in companies we believe are related to our strategic objectives. We could from time to time
seek to raise additional funds through the issuance of debt or equity securities for larger acquisitions.

The increase in cash and investments at December 31, 2010 as compared to December 31, 2009, is primarily

due to cash provided by our operating activities of $616.3 million and cash received from the issuance of
common stock under our employee stock-based compensation plans of $353.6 million partially offset by
expenditures made on our stock repurchases of $433.7 million and purchases of property and equipment of $75.4
million. We generally invest our cash and cash equivalents in investment grade, highly liquid securities to allow
for flexibility in the event of immediate cash needs. Our short-term and long-term investments primarily consist
of interest-bearing securities. See “—Liquidity and Capital Resources” and Note 4 to our consolidated financial
statements included in this Annual Report on Form 10-K for the year ended December 31, 2010 for further
information.

Trading Investments

We held municipal auction rate securities, the majority of which were triple-A rated, whose underlying
assets were generally student loans that were substantially backed by the federal government under the Federal
Family Education Loan Program through investment accounts managed by UBS Financial Services, Inc., or
UBS. The market for municipal auction rate securities in our portfolio began experiencing auction failures in
2008. In November 2008, we formally accepted the terms of a settlement, or the Settlement, from UBS. Upon
accepting the terms of the Settlement, we received an enforceable, non-transferrable right, or the Put Option, that
enabled us to sell our auction rate securities back to UBS. On June 30, 2010, we exercised the Put Option and
sold all of our remaining investments in auction rate securities back to UBS at par. During 2010, we realized a
gain of $6.0 million related to the sale of our investments in auction rate securities and a corresponding loss of
$6.0 million related to the settlement of the Put Option, both of which are included in other (expense) income,
net, in our consolidated statements of income. See Notes 4 and 5 to our consolidated financial statements.

Fair Value Measurements

The authoritative guidance defines fair value as an exit price, representing the amount that would either be

received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As

55

such, fair value is a market-based measurement that should be determined based on assumptions that market
participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance
establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

•

•

•

Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities;

Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or
indirectly; and

Level 3. Unobservable inputs in which there is little or no market data, which require the reporting
entity to develop its own assumptions.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

We measure our cash flow hedges at fair value based on indicative prices in active markets and we generally
measure our investments in available-for-sale securities at fair value based on quoted prices in active markets for
identical securities.

We currently hold one available-for-sale investment for which quoted prices are not readily available, our
$50.0 million face value investment issued by AIG Matched Funding Corporation, or the AIG Capped Floater. In
order to measure the AIG Capped Floater at fair value we used a discounted cash flow model. We then
discounted those cash flows at a rate reflecting the market risk inherent in holding an AIG security with a similar
maturity as evidenced by pricing in the markets. Since utilizing a discounted cash flow model required us to
make assumptions that were not directly or indirectly observable regarding the AIG Capped Floater’s fair value.
Accordingly, it is a Level 3 valuation and is included in the table below.

Compared to

56

The increase in accounts receivable at December 31, 2010 compared to December 31, 2009 was primarily

due to an increase in sales, particularly in the last month of 2010 compared to the last month of 2009. The
increase in our allowance for returns when comparing 2010 to 2009 was not significant. The activity in our
allowance for returns was comprised of $3.2 million in credits issued for returns during 2010 offset by $2.4
million of provisions for returns recorded during 2010. Our allowance for doubtful accounts remained relatively
constant when comparing 2010 to 2009. The activity in our allowance for doubtful accounts was primarily
comprised of additional provisions for doubtful accounts of $2.0 million recorded during the year partially offset
by $1.8 million of uncollectible accounts written off, net of recoveries during the year.

From time to time, we could maintain individually significant accounts receivable balances from our
distributors or customers, which are comprised of large business enterprises, governments and small and
medium-sized businesses. If the financial condition of our distributors or customers deteriorates, our operating
results could be adversely affected. At December 31, 2010, one distributor, Ingram Micro, accounted for 17% of
our accounts receivable. At December 31, 2009, one distributor, Ingram Micro, accounted for 14% of our
accounts receivable. For more information regarding significant customers see Note 12 to our consolidated
financial statements included in this Annual Report on Form 10-K for the year ended December 31, 2010.

Credit Facility

Effective on August 9, 2005, we entered into a revolving credit facility, or the Credit Facility, with a group

of financial institutions, or the Lenders. Effective September 27, 2006, we entered into an amendment and
restatement of the Credit Facility, or the Amendment. The Amendment decreased the overall range of interest we
will pay on amounts outstanding on the Credit Facility and lowered the facility fee. In addition, the Amendment
extended the term of the Credit Facility. The Credit Facility, as amended, allows us to increase the revolving
credit commitment up to a maximum aggregate revolving credit commitment of $175.0 million. The Credit
Facility, as amended, will expire on September 27, 2011 and it currently provides for a revolving line of credit in
the aggregate amount of $100.0 million, subject to continued covenant compliance. A portion of the revolving
line of credit (1) in the aggregate amount of $25.0 million may be available for issuances of letters of credit and
(2) in the aggregate amount of $15.0 million may be available for swing line loans. The Credit Facility, as
amended, currently bears interest at the London Interbank Offered Rate, or LIBOR, plus 0.32% and adjusts in the
future in the range of 0.32% to 0.80% above LIBOR based on the level of our total debt and our adjusted
earnings before interest, taxes, depreciation and amortization, or EBITDA. In addition, we are required to pay an
annual facility fee ranging from 0.08% to 0.20% based on the aggregate amount available under the Credit
Facility, as amended, and the level of our total debt and adjusted EBITDA. During the year ended December 31,
2010, no borrowings were made under the Credit Facility, as amended, and as of December 31, 2010 there were
no amounts outstanding under the Credit Facility, as amended.

The Credit Facility, as amended, contains customary default provisions, and we must comply with various
financial and non-financial covenants. The financial covenants consist of a minimum interest coverage ratio and
a maximum consolidated leverage ratio. The primary non-financial covenants contain certain limits on our ability
to pay dividends, conduct certain mergers or acquisitions, make certain investments and loans, incur future
indebtedness or liens, alter our capital structure or sell stock or assets. As of December 31, 2010, we were in
compliance with all covenants of the Credit Facility.

Stock Repurchase Program

Our Board of Directors authorized an ongoing stock repurchase program with a total repurchase authority
granted to us of $2.5 billion. We may use the approved dollar authority to repurchase stock at any time until the
approved amounts are exhausted. The objective of our stock repurchase program is to improve stockholders’
returns. At December 31, 2010, approximately $120.3 million was available to repurchase common stock
pursuant to the stock repurchase program. All shares repurchased are recorded as treasury stock. A portion of the
funds used to repurchase stock over the course of the program was provided by proceeds from employee stock
option exercises and the related tax benefit.

57

We are authorized to make open market purchases of our common stock using general corporate funds.

Additionally, from time to time, we have entered into structured stock repurchase arrangements with large
financial institutions using general corporate funds in order to lower the average cost to acquire shares. These
programs include terms that require us to make up-front payments to the counterparty financial institution and
result in the receipt of stock during or at the end of the agreement or the receipt of either stock or cash at the
maturity of the agreement, depending on market conditions.

During the year ended December 31, 2010, we expended approximately $434.8 million on open market

purchases, repurchasing 8,157,400 shares of outstanding common stock at an average price of $53.31. In
addition, during the third quarter of 2010, we made an up-front payment of $15.0 million to a financial institution
related to a structured stock repurchase agreement. At the maturity of the agreement in the fourth quarter of 2010,
we received $16.1 million in cash, including premiums, and did not take delivery of any shares related to the
agreement due to market conditions. As of December 31, 2010, we did not have any prepaid notional amounts
outstanding related to our structured stock repurchase programs.

During the year ended December 31, 2009, we expended approximately $214.9 million on open market
purchases, repurchasing 6,475,830 shares of outstanding common stock at an average price of $33.19.As of
December 31, 2009, we did not have any prepaid notional amounts outstanding under our structured stock
repurchase programs and during the year we did not make any up-front payments to financial institutions related
to structured stock repurchase agreements.

During the year ended December 31, 2008, we took delivery of 4,406,757 shares at an average price of
$33.30 per share from our structured repurchase agreements and we expended approximately $197.6 million on
open market purchases repurchasing 6,451,591 shares of outstanding common stock at an average price of
$30.63. As of December 31, 2008, we did not have any prepaid notional amounts outstanding under our
structured stock repurchase programs.

Shares for Tax Withholding

During the year ended December 31, 2010, we withheld 123,489 shares from vested stock units totaling

$6.3 million to satisfy tax withholding obligations that arose on the vesting of stock units. These shares are
reflected as treasury stock in our consolidated balance sheet and the related cash outlays reduce our total
repurchase authority.

During the year ended December 31, 2009, we withheld 46,732 shares from vested stock units totaling $1.8

million to satisfy tax withholding obligations that arose on the vesting of stock units. These shares are reflected
as treasury stock in our consolidated balance sheet and the related cash outlays reduce our total repurchase
authority.

Contractual Obligations and Off-Balance Sheet Arrangement

Contractual Obligations

We have certain contractual obligations that are recorded as liabilities in our consolidated financial

statements. Other items, such as operating lease obligations, are not recognized as liabilities in our consolidated
financial statements, but are required to be disclosed in the notes to our consolidated financial statements.

58

The following table summarizes our significant contractual obligations at December 31, 2010 and the future

periods in which such obligations are expected to be settled in cash. Additional details regarding these
obligations are provided in the notes to our consolidated financial statements (in thousands):

Purchase obligations represent non-cancelable commitments to purchase inventory ordered before year-end
of approximately $9.7 million and a contingent obligation to purchase inventory, which is based on amount
of usage, of approximately $8.4 million.
Total contractual obligations do not include agreements where our commitment is variable in nature or
where cancellations without payment provisions exist and excludes $63.9 million of liabilities related to
uncertain tax positions recorded in accordance with authoritative guidance, because we could not make
reasonably reliable estimates of the period or amount of cash settlement with the respective taxing
authorities. See Note 11 to our consolidated financial statements included in this Annual Report on Form
10-K for the year ended December 31, 2010 for further information.

As of December 31, 2010, we did not have any individually material capital lease obligations or other

material long-term commitments reflected on our consolidated balance sheets.

Commitments

Capital expenditures were $75.4 million during 2010, $76.2 million during 2009 and $181.0 million during

2008. During 2010 and 2009, capital expenditures were primarily related to application and infrastructure
delivery to enable growth and enhance management reporting capabilities and leasehold improvements.

Office Leases

We have operating lease obligations through 2018 related to two properties that are not utilized. At

December 31, 2010, the total remaining obligation on these lease obligations was approximately $6.4 million, of
which $2.9 million was accrued as of December 31, 2010, and is reflected in accrued expenses and other current
liabilities and other liabilities in our consolidated financial statements. In calculating these accruals, we made
estimates, based on market information, including the estimated vacancy periods and sublease rates and
opportunities. We periodically re-evaluate our estimates related to the vacant facilities.

Off-Balance Sheet Arrangements

The Company does not have any special purpose entities or off-balance sheet financing arrangements.

59

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The following discussion about our market risk includes “forward-looking statements” that involve risks

and uncertainties. Actual results could differ materially from those projected in the forward-looking statements.
The analysis methods we used to assess and mitigate risk discussed below should not be considered projections
of future events, gains or losses.

We are exposed to financial market risks, including changes in foreign currency exchange rates and interest

rates that could adversely affect our results of operations or financial condition. To mitigate foreign currency
risk, we utilize derivative financial instruments. The counterparties to our derivative instruments are major
financial institutions. All of the potential changes noted below are based on sensitivity analyses performed on our
financial position as of December 31, 2010. Actual results could differ materially.

Discussions of our accounting policies for derivatives and hedging activities are included in Notes 2 and 14

to our consolidated financial statements included in this Annual Report on Form 10-K for the year ended
December 31, 2010.

Exposure to Exchange Rates

A substantial majority of our overseas expense and capital purchasing activities are transacted in local
currencies, including Euros, British pounds sterling, Japanese yen, Australian dollars, Swiss francs, Indian
rupees, Hong Kong dollars, Canadian dollars, Singapore dollars and Chinese renminbi. To reduce our exposure
to a reduction in U.S. dollar value and the volatility of future cash flows caused by changes in currency exchange
rates, we have established a hedging program. We use foreign currency forward contracts to hedge certain
forecasted foreign currency expenditures. Our hedging program significantly reduces, but does not entirely
eliminate, the impact of currency exchange rate movements.

At December 31, 2010 and 2009, we had in place foreign currency forward sale contracts with a notional
amount of $98.5 million and $33.6 million, respectively, and foreign currency forward purchase contracts with a
notional amount of $244.7 million and $224.7 million, respectively. At December 31, 2010, these contracts had
an aggregate fair asset value of $6.4 million and at December 31, 2009, these contracts had an aggregate fair
asset value of $4.8 million. Based on a hypothetical 10% appreciation of the U.S. dollar from December 31, 2010
market rates, the fair value of our foreign currency forward contracts would decrease by $15.3 million, resulting
in a net liability position. Conversely, a hypothetical 10% depreciation of the U.S. dollar from December 31,
2010 market rates would increase the fair value of our foreign currency forward contracts by $15.3 million. In
these hypothetical movements, foreign operating costs would move in the opposite direction. This calculation
assumes that each exchange rate would change in the same direction relative to the U.S. dollar. In addition to the
direct effects of changes in exchange rates quantified above, changes in exchange rates could also change the
dollar value of sales and affect the volume of sales as the prices of our competitors’ products become more or
less attractive. We do not anticipate any material adverse impact to our consolidated financial position, results of
operations, or cash flows as a result of these foreign exchange forward contracts.

Exposure to Interest Rates

We have interest rate exposures resulting from our interest-based available-for-sale. We maintain

available-for-sale investments in debt securities and we limit the amount of credit exposure to any one issuer or
type of instrument. The securities in our investment portfolio are not leveraged. The securities classified as
available-for-sale are subject to interest rate risk. The modeling technique used measures the change in fair
values arising from an immediate hypothetical shift in market interest rates and assumes that ending fair values
include principal plus accrued interest and reinvestment income. If market interest rates were to increase by 100
basis points from December 31, 2010 and 2009 levels, the fair value of the available-for-sale portfolio would
decline by approximately $15.2 million and $8.6 million, respectively. If market interest rates were to decrease
by 100 basis points from December 31, 2010 and 2009 levels, the fair value of the available-for-sale portfolio

60

would increase by approximately $8.9 million and $3.8 million, respectively. These amounts are determined by
considering the impact of the hypothetical interest rate movements on our available-for-sale and trading
investment portfolios. This analysis does not consider the effect of credit risk as a result of the changes in overall
economic activity that could exist in such an environment.

During 2005, we entered into the Credit Facility, as amended in 2006, or the Amended Credit Facility.
Accordingly, we could be exposed to market risk from changes in interest rates on our long-term debt. This
exposure relates to our $100.0 million Amended Credit Facility. Borrowings under the Amended Credit Facility
currently bear interest at variable rates based on LIBOR plus 0.32% and adjusts in the future in the range of
0.32% to 0.80% above LIBOR based on our level of total debt and our adjusted earnings before interest, taxes,
depreciation and amortization, or EBITDA. A hypothetical 1% interest rate change would not have any current
impact on our results of operations as we had no amounts outstanding under the Amended Credit Facility as of
December 31, 2010.

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of December 31, 2010, our management, with the participation of our President and Chief Executive
Officer and our Senior Vice President and Chief Financial Officer, evaluated the effectiveness of our disclosure
controls and procedures pursuant to Rule 13a-15(b) promulgated under the Securities Exchange Act of 1934, as
amended, or the Exchange Act. Based upon that evaluation, our President and Chief Executive Officer and our
Senior Vice President and Chief Financial Officer concluded that, as of December 31, 2010, our disclosure
controls and procedures were effective in ensuring that material information required to be disclosed in the
reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the
time periods specified in the Securities and Exchange Commission’s rules and forms, including ensuring that
such material information is accumulated and communicated to our management, including our President and
Chief Executive Officer and our Senior Vice President and Chief Financial Officer, as appropriate to allow
timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

During the quarter ended December 31, 2010, there were no changes in our internal control over financial

reporting that have materially affected, or are reasonably likely to materially affect, our internal control over
financial reporting.

Management’s Annual Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial
reporting as such term is defined in Exchange Act Rule 13a-15(f). Our internal control system was designed to
provide reasonable assurance to our management and the Board of Directors regarding the preparation and fair
presentation of published financial statements. All internal control systems, no matter how well designed have
inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable
assurance with respect to financial statement preparation and presentation. Our management assessed the
effectiveness of our internal control over financial reporting as of December 31, 2010. In making this assessment,
our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway
Commission, or COSO, in Internal Control—Integrated Framework (the COSO criteria). Based on our
assessment we believe that, as of December 31, 2010, our internal control over financial reporting is effective
based on those criteria. The effectiveness of our internal control over financial reporting as of December 31,
2010 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in
their report which appears below.

62

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Citrix Systems, Inc.

We have audited Citrix Systems, Inc.’s internal control over financial reporting as of December 31, 2010, based
on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission (the COSO criteria). Citrix Systems, Inc.’s management is
responsible for maintaining effective internal control over financial reporting, and for its assessment of the
effectiveness of internal control over financial reporting included in the accompanying Management’s Annual
Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the
company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether effective internal control over financial reporting was maintained in all material respects. Our audit
included obtaining an understanding of internal control over financial reporting, assessing the risk that a material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the
assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe
that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes in
accordance with generally accepted accounting principles. A company’s internal control over financial reporting
includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail,
accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable
assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance
with generally accepted accounting principles, and that receipts and expenditures of the company are being made
only in accordance with authorizations of management and directors of the company; and (3) provide reasonable
assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the
company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

In our opinion, Citrix Systems, Inc. maintained, in all material respects, effective internal control over financial
reporting as of December 31, 2010, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), the consolidated balance sheets of Citrix Systems, Inc. as of December 31, 2010 and 2009, and
the related consolidated statements of income, equity and comprehensive income, and cash flows for each of the
three years in the period ended December 31, 2010 of Citrix Systems, Inc. and our report dated February 24,
2011 expressed an unqualified opinion thereon.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of Citrix Systems, Inc.

We have audited the accompanying consolidated balance sheets of Citrix Systems, Inc. as of December 31, 2010
and 2009, and the related consolidated statements of income, equity and comprehensive income, and cash flows
for each of the three years in the period ended December 31, 2010. Our audits also included the financial
statement schedule listed in the Index at Item 15(a). These financial statements and schedule are the
responsibility of the Company’s management. Our responsibility is to express an opinion on these financial
statements and schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board
(United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the
accounting principles used and significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated
financial position of Citrix Systems, Inc. at December 31, 2010 and 2009, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended December 31, 2010, in conformity
with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule,
when considered in relation to the basic financial statements taken as a whole, presents fairly in all material
respects the information set forth therein.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board
(United States), Citrix Systems, Inc.’s internal control over financial reporting as of December 31, 2010, based
on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission and our report dated February 24, 2011 expressed an unqualified
opinion thereon.

computing. The Company markets and licenses its products directly to enterprise customers, over the web, and
through systems integrators (“SIs”), in addition to indirectly through value-added resellers (“VARs”), value-
added distributors (“VADs”) and original equipment manufacturers (“OEMs”).

2. SIGNIFICANT ACCOUNTING POLICIES

Consolidation Policy

The consolidated financial statements of the Company include the accounts of its wholly-owned subsidiaries

in the Americas, Europe, the Middle East and Africa (“EMEA”), Asia-Pacific and the Online Services division.
All significant transactions and balances between the Company and its subsidiaries have been eliminated in
consolidation. In addition, the Company presents non-controlling interests within the equity section of its
consolidated financial statements in accordance with the revised authoritative guidance for the presentation and
disclosure of non-controlling interests of a consolidated subsidiary.

Cash and Cash Equivalents

Cash and cash equivalents at December 31, 2010 and 2009 include marketable securities, which are
primarily money market funds, commercial paper, agency and government securities, municipal securities and
corporate securities with initial or remaining contractual maturities when purchased of three months or less.

Investments

Short-term and long-term investments at December 31, 2010 and 2009 primarily consist of agency
securities, corporate securities, government securities, municipal securities and commercial paper. Investments
classified as available-for-sale are stated at fair value with unrealized gains and losses, net of taxes, reported in
accumulated other comprehensive income (loss). Investments classified as trading securities are stated at fair
value with unrealized gains and losses reported in earnings. The Company classifies its available-for-sale
investments as current and non-current based on their actual remaining time to maturity. The Company does not
recognize changes in the fair value of its available-for-sale investments in income unless a decline in value is
considered other-than-temporary in accordance with the authoritative guidance.

The Company’s investment policy is designed to limit exposure to any one issuer depending on credit

quality. The Company uses information provided by third parties to adjust the carrying value of certain of its
investments to fair value at the end of each period. Fair values are based on valuation models that use market
quotes and, for certain investments, assumptions as to the creditworthiness of the entities issuing those
underlying instruments.

Accounts Receivable

The Company’s accounts receivable are due primarily from VARs, VADs and end customers. Collateral is
not required. The Company also maintains allowances for doubtful accounts for estimated losses resulting from

F-9

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

the inability of the Company’s customers to make payments. The Company periodically reviews these estimated
allowances, including an analysis of the customers’ payment history and creditworthiness, the age of the trade
receivable balances and current economic conditions that may affect a customer’s ability to pay and it
specifically reserve for those deemed uncollectible. When receivables are charged off, principal amounts of
receivables outstanding are deducted from the allowance. The allowance for doubtful accounts was $3.4 million
and $3.2 million as of December 31, 2010 and 2009, respectively. If the financial condition of a significant
distributor or customer were to deteriorate, the Company’s operating results could be adversely affected. One
distributor, Ingram Micro, accounted for 17% and 14% of gross accounts receivable at December 31, 2010 and
2009, respectively.

Inventory

Inventories are stated at the lower of cost or market on a standard cost basis, which approximates actual

cost. The Company’s inventories primarily consist of finished goods as of December 31, 2010 and 2009.

Property and Equipment

Property and equipment is stated at cost. Depreciation is computed using the straight-line method over the

estimated useful lives of the assets, which is generally three years for computer equipment, software, office
equipment and furniture, the lesser of the lease term or five years for leasehold improvements, which is the
estimated useful life, seven years for the Company’s enterprise resource planning system and 40 years for
buildings.

During 2010 and 2009, the Company retired $8.9 million and $42.4 million, respectively, in property and
equipment that were no longer in use. At the time of retirement, the remaining net book value of these assets was
immaterial and no material asset retirement obligations were associated with them.

Property and equipment consist of the following:

Long-Lived Assets

The Company reviews for impairment of long-lived assets and certain identifiable intangible assets to be
held and used whenever events or changes in circumstances indicate that the carrying amount of such assets may
not be fully recoverable. Determination of recoverability is based on an estimate of undiscounted future cash

F-10

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

flows resulting from the use of the asset and its eventual disposition. Measurement of an impairment loss is based
on the fair value of the asset compared to its carrying value. Long-lived assets and certain identifiable intangible
assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

During 2010 and 2008, the Company did not recognize any impairment charges associated with its long-
lived or intangible assets. During 2009, the Company recognized impairment charges associated with its long-
lived assets of $4.2 million primarily related to information systems.

Goodwill

The Company accounts for goodwill in accordance with the authoritative guidance, which requires that
goodwill and certain intangible assets are not amortized, but are subject to an annual impairment test. There was
no impairment of goodwill as a result of the annual impairment tests completed during the fourth quarters of
2010 and 2009. Excluding goodwill, the Company has no intangible assets deemed to have indefinite lives. See
Note 3 for acquisitions and Note 12 for segment information.

(1) Amount primarily consists of adjustment made by the Company after it determined that it had incorrectly

recorded acquisition-related payments to certain employees in connection with the October 2007 acquisition
of XenSource, Inc. as purchase consideration and goodwill when it should have been recorded as
compensation expense. Accordingly, the Company recorded $5.4 million of compensation expense in 2009
related to this item with a corresponding decrease to goodwill.

Intangible Assets

The Company has intangible assets which were primarily acquired in conjunction with business

combinations and technology purchases. Intangible assets with finite lives are recorded at cost, less accumulated
amortization. Amortization is recognized on a straight-line basis over the estimated useful lives of the respective
assets, generally three to seven years, except for patents, which are amortized over the lesser of their remaining
life or ten years. In accordance with the authoritative guidance, the Company records acquired product related
intangible assets at net realizable value and reviews this technology for impairment on a periodic basis by
comparing the estimated net realizable value to the unamortized cost of the technology. As of December 31,
2010, the Company had $29.8 million in unamortized acquired product related intangibles and recorded $9.2
million in amortization during the year ended December 31, 2010 related to these assets. There have been no
material impairments of these assets for any of the periods presented.

Software Development Costs

The authoritative guidance requires certain internal software development costs related to software to be

sold to be capitalized upon the establishment of technological feasibility. Software development costs incurred
subsequent to achieving technological feasibility have not been significant and substantially all software
development costs have been expensed as incurred.

Internal Use Software

In accordance with the authoritative guidance, the Company capitalizes external direct costs of materials

and services and internal costs such as payroll and benefits of those employees directly associated with the
development of new functionality in internal use software and software developed related to its online service
offerings. The amount of costs capitalized in 2010 and 2009 relating to internal use software was $37.7 million
and $41.5 million, respectively. These costs are being amortized over the estimated useful life of the software,
which is generally three to seven years, and are included in property and equipment in the accompanying
consolidated balance sheets.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Revenue Recognition

The Company markets and licenses products primarily through multiple channels such as VARs, VADs,

SIs, independent software vendors, its websites and OEMs. The Company’s product licenses are generally
perpetual. The Company also separately sells license updates and services, which may include product training,
technical support and consulting services, as well as online services.

The Company’s software products are purchased by both small and medium-sized businesses, with a
minimal number of locations, and larger business enterprises with more complex multiserver environments that
deploy the Company’s software products on a departmental or enterprise-wide basis. Products may be delivered
indirectly by channel distributors or OEMs or directly to the end-user by the Company via packaged product or
download from the Company’s website.

The Company licenses most of its software products bundled with a one year contract for its Subscription
Advantage program. Customers may also elect to purchase subscriptions for license updates, when not bundled
with the initial product purchase. Technical support, product training or consulting services may be purchased
separately by the customer. The Company’s appliance products are integrated with software that is essential to
the functionality of the equipment. Accordingly, for these hardware appliances, the Company accounts for
revenue in accordance with authoritative guidance governing software revenue recognition. Unspecified software
upgrades made available on a when and if available basis, enhancements and technical support can be purchased
for the Company’s appliance products through its maintenance contracts. Effective January 1, 2011, the
Company adopted the provisions of Accounting Standards Update (“ASU”) 2009-14, Software (Topic 985):
Certain Revenue Arrangements That Include Software Elements, and ASU 2009-13, Revenue Recognition (Topic
605): Multiple-Deliverable Revenue Arrangements. The adoption of these standards is not expected to have a
material impact on the Company’s financial position and results of operations. See Note 16.

The Company allocates revenue to license updates and any other undelivered elements of the arrangement

based on VSOE of fair value of each element and such amounts are deferred until the applicable delivery criteria
and other revenue recognition criteria described above have been met. The balance of the revenues, net of any
discounts inherent in the arrangement, is recognized at the outset of the arrangement using the residual method as
the product licenses are delivered. If management cannot objectively determine the fair value of each undelivered
element based on the vendor specific objective evidence (“VSOE”) of fair value, revenue recognition is deferred
until all elements are delivered, all services have been performed, or until fair value can be objectively
determined.

Online services are sold separately. The Company’s online services are purchased by large enterprises,

small and medium-sized businesses, as well as individuals, and are centrally hosted within the Company’s
datacenters. The Company’s online services are considered service arrangements per the authoritative guidance,
accordingly, the Company follows the provisions of Securities and Exchange Commission Staff Accounting
Bulletin (“SAB”) No. 104, Revenue Recognition, when accounting for these service arrangements. Generally, the
Company’s online services are sold separately and not bundled with the Enterprise division’s products and
services.

The Company recognizes revenue when it is earned and when all of the following criteria are met:
persuasive evidence of the arrangement exists; delivery has occurred or the service has been provided and the
Company has no remaining obligations; the fee is fixed or determinable; and collectability is probable. The
Company defines these four criteria as follows:

• Persuasive evidence of the arrangement exists. The Company recognizes revenue on packaged
products and appliances upon shipment to distributors and resellers. For packaged product and

F-13

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

appliance sales, it is the Company’s customary practice to require a purchase order from distributors
and resellers who have previously negotiated a master packaged product distribution or resale
agreement. For electronic and paper license arrangements, the Company typically requires a purchase
order from the distributor, reseller or end-user (depending on the arrangement) and an executed product
license agreement from the end-user. For technical support, product training and consulting services,
the Company requires a purchase order and an executed agreement. For online services, the Company
requires the customer or the reseller to electronically accept the terms of an online services agreement
or execute a contract.

• Delivery has occurred and the Company has no remaining obligations. For product license and

hardware appliance sales, the Company’s standard delivery method is free-on-board shipping point.
Consequently, it considers delivery of packaged products and appliances to have occurred when the
products are shipped pursuant to an agreement and purchase order. The Company considers delivery of
licenses under electronic licensing agreements to have occurred when the related products are shipped
and the end-user has been electronically provided the software activation keys that allow the end-user
to take immediate possession of the product. For online services, delivery occurs upon providing the
users with their login id and password. For product training and consulting services, the Company
fulfills its obligation when the services are performed. For license updates, technical support and online
services, the Company assumes that its obligation is satisfied ratably over the respective terms of the
agreements, which are typically 12 to 24 months.

•

The fee is fixed or determinable. In the normal course of business, the Company does not provide
customers the right to a refund of any portion of their license fees or extended payment terms. The
Company sells license updates and services, which includes technical support, product training and
consulting services separately. Fees are considered fixed and determinable upon establishment of an
arrangement that contains the final terms of the sale including description, quantity and price of each
products or service purchased. For online services, the fee is considered fixed or determinable if it is
not subject to refund or adjustment.

• Collectability is probable. The Company determines collectability on a customer-by-customer basis
and generally does not require collateral. The Company typically sells product licenses and license
updates to distributors or resellers for whom there are histories of successful collection. New customers
are typically subject to a credit review process that evaluates their financial position and ultimately
their ability to pay. Customers are also subject to an ongoing credit review process. If the Company
determines from the outset of an arrangement that collectability is not probable, revenue recognition is
deferred until customer payment is received and the other parameters of revenue recognition described
above have been achieved. Management’s judgment is required in assessing the probability of
collection, which is generally based on an evaluation of customer specific information, historical
experience and economic market conditions.

Net revenues include the following categories: Product Licenses, License Updates, Online Services and
Technical Services. Product License revenues primarily represent fees related to the licensing of the Company’s
software and hardware appliance products. These revenues are reflected net of sales allowances, cooperative
advertising agreements, reseller rewards and provisions for returns. License Update revenues consist of fees
related to the Subscription Advantage program that are recognized ratably over the term of the contract, which is
typically 12 to 24 months. Subscription Advantage is a renewable program that provides subscribers with
immediate access to software upgrades, enhancements and maintenance releases when and if they become
available during the term of the contract. The Company capitalizes certain third party commissions related to
Subscription Advantage renewals. The capitalized commissions are amortized to Sales, Marketing and Services
expense at the time the related deferred revenue is recognized as revenue. Online Services revenues consist

F-14

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

primarily of fees related to online service agreements, which are recognized ratably over the contract term. In
addition, Online Services revenues may also include set-up fees, which are recognized ratably over the contract
term or the expected customer life, whichever is longer. Technical Services revenues are comprised of fees from
technical support services which are recognized ratably over the contract term as well as revenues from product
training and certification, and consulting services revenue related to the implementation of the Company’s
products, which is recognized as the services are provided. In the normal course of business, the Company is not
obligated to accept product returns from its distributors under any conditions, unless the product item is defective
in manufacture. The Company establishes provisions for estimated returns, as well as other sales allowances,
concurrently with the recognition of revenue. The provisions are established based upon consideration of a
variety of factors, including, among other things, recent and historical return rates for both specific products and
distributors and the impact of any new product releases and projected economic conditions. The Company’s
ability to recognize revenue upon shipment to distributors is predicated on its ability to reliably estimate future
returns. If actual experience or changes in market conditions impair the Company’s ability to estimate returns, it
would be required to defer the recognition of revenue until the delivery of the product to the end-user. Product
returns are provided for in the consolidated financial statements and have historically been within management’s
expectations. Allowances for estimated product returns amounted to approximately $0.9 million and $1.6 million
at December 31, 2010 and December 31, 2009, respectively. The Company also records estimated reductions to
revenue for customer programs and incentive offerings including volume-based incentives. The Company could
take actions to increase its customer incentive offerings, which could result in an incremental reduction to
revenue at the time the incentive is offered.

Product Concentration

The Company derives a substantial portion of its revenues from its Desktop Solutions products, which
include its XenDesktop and XenApp products and related services, and anticipates that these products and future
derivative products and product lines based upon this technology will continue to constitute a majority of its
revenue. The Company could experience declines in demand for its Desktop Solutions and other products,
whether as a result of general economic conditions, the delay or reduction in technology purchases, new
competitive product releases, price competition, lack of success of its strategic partners, technological change or
other factors.

Cost of Net Revenues

Cost of product license revenues consists primarily of hardware, product media and duplication, manuals,
packaging materials, shipping expense, server capacity costs and royalties. In addition, the Company is a party to
licensing agreements with various entities, which give the Company the right to use certain software code in its
products or in the development of future products in exchange for the payment of fixed fees or amounts based
upon the sales of the related product. The licensing agreements generally have terms ranging from one to five
years, and generally include renewal options. However, some agreements may be perpetual unless expressly
terminated. Royalties and other costs related to these agreements are included in cost of net revenues. Cost of
services revenue consists primarily of compensation and other personnel-related costs of providing technical
support and consulting, as well as the Company’s online services. Also included in cost of net revenues is
amortization of product related intangible assets which includes acquired core and product technology and
associated patents.

Foreign Currency

The functional currency for substantially all of the Company’s wholly-owned foreign subsidiaries is the
U.S. dollar. Monetary assets and liabilities of the subsidiaries are remeasured into U.S. dollars at exchange rates

F-15

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

in effect at the balance sheet date, and revenues and expenses are remeasured at average rates prevailing during
the year. Remeasurement and foreign currency transaction gains (losses) of approximately $3.5 million, $4.1
million and $(6.0) million for the years ended December 31, 2010, 2009, and 2008, respectively, are included in
other (expense) income, net, in the accompanying consolidated statements of income.

Derivatives and Hedging Activities

In accordance with the authoritative guidance, the Company records derivatives at fair value as either assets
or liabilities on the balance sheet. For derivatives that are designated as and qualify as effective cash flow hedges,
the portion of gain or loss on the derivative instrument effective at offsetting changes in the hedged item is
reported as a component of accumulated other comprehensive income (loss) and reclassified into earnings as
operating expense, net, when the hedged transaction affects earnings. For derivative instruments that are
designated as and qualify as effective fair value hedges, the gain or loss on the derivative instrument as well as
the offsetting gain or loss on the hedged item attributable to the hedged risk, is recognized in current earnings as
interest income or interest expense during the period of the change in fair values. Derivatives not designated as
hedging instruments are adjusted to fair value through earnings as other (expense) income, net, in the period the
changes in fair value occur. The application of the authoritative guidance could impact the volatility of earnings.

The Company formally documents all relationships between hedging instruments and hedged items, as well
as its risk-management objective and strategy for undertaking various hedge transactions. This process includes
attributing all derivatives that are designated as cash flow hedges to floating rate assets or liabilities or forecasted
transactions and attributing all derivatives that are designated as fair value hedges to fixed rate assets or
liabilities. The Company also formally assesses, both at the inception of the hedge and on an ongoing basis,
whether each derivative is highly effective in offsetting changes in cash flows or fair value of the hedged item.
Fluctuations in the value of the derivative instruments are generally offset by changes in the hedged item;
however, if it is determined that a derivative is not highly effective as a hedge or if a derivative ceases to be a
highly effective hedge, the Company will discontinue hedge accounting prospectively for the affected derivative.

The Company is exposed to risk of default by its hedging counterparties. Although this risk is concentrated

among a limited number of counterparties, the Company’s foreign exchange hedging policy attempts to minimize
it by placing limits on the amount of exposure that may exist with any single financial institution at a time.

Pension Liability

The Company provides retirement benefits to certain employees who are not U.S. based. Generally, benefits

under these programs are based on an employee’s length of service and level of compensation. The majority of
these programs are commonly referred to as termination indemnities, which provide retirement benefits in
accordance with programs mandated by the governments of the countries in which such employees work.

The Company had accrued $5.2 million and $3.0 million for these pension liabilities at December 31, 2010

and 2009, respectively. Expenses for the program for 2010, 2009 and 2008 amounted to $1.1 million, $1.4
million and $0.9 million, respectively.

Advertising Costs

The Company expenses advertising costs as incurred. The Company has advertising agreements with, and
purchases advertising from, online media providers to advertise its online services products. The Company also
has cooperative advertising agreements with certain distributors and resellers whereby the Company will
reimburse distributors and resellers for qualified advertising of Citrix products. Reimbursement is made once the

F-16

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

distributor, reseller or provider provides substantiation of qualified expenses. The Company estimates the impact
of these expenses and recognizes them at the time of product sales as a reduction of net revenue in the
accompanying consolidated statements of income. The total costs the Company recognized related to advertising
was approximately $123.0 million, $99.2 million and $84.6 million, during the years ended December 31, 2010,
2009 and 2008, respectively.

Income Taxes

The Company and one or more of its subsidiaries is subject to United States federal income taxes, as well as

income taxes of multiple state and foreign jurisdictions. With few exceptions, the Company is no longer subject
to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for years prior to 2004.

In the ordinary course of global business, there are transactions for which the ultimate tax outcome is
uncertain; thus, judgment is required in determining the worldwide provision for income taxes. The Company
provides for income taxes on transactions based on its estimate of the probable liability. The Company adjusts its
provision as appropriate for changes that impact its underlying judgments. Changes that impact provision
estimates include such items as jurisdictional interpretations on tax filing positions based on the results of tax
audits and general tax authority rulings. Due to the evolving nature of tax rules combined with the large number
of jurisdictions in which the Company operates, estimates of its tax liability and the realizability of its deferred
tax assets could change in the future, which may result in additional tax liabilities and adversely affect the
Company’s results of operations, financial condition and cash flows.

The Company is required to estimate its income taxes in each of the jurisdictions in which it operates as part

of the process of preparing its consolidated financial statements. The authoritative guidance requires a valuation
allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than
not that some portion or all of the deferred tax assets will not be realized. The Company reviews deferred tax
assets periodically for recoverability and makes estimates and judgments regarding the expected geographic
sources of taxable income and gains from investments, as well as tax planning strategies in assessing the need for
a valuation allowance.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the
United States requires management to make estimates and assumptions that affect the amounts reported in the
consolidated financial statements and accompanying notes. Significant estimates made by management include
the provision for doubtful accounts receivable, the provision to reduce obsolete or excess inventory to market, the
provision for estimated returns, as well as sales allowances, the assumptions used in the valuation of stock-based
awards, the assumptions used in the discounted cash flows to mark certain of its investments to market, the
valuation of the Company’s goodwill, net realizable value of product related intangible assets, the provision for
vacant facility costs, the provision for income taxes and the amortization and depreciation periods for intangible
and long-lived assets. While the Company believes that such estimates are fair when considered in conjunction
with the consolidated financial position and results of operations taken as a whole, the actual amounts of such
items, when known, will vary from these estimates.

Accounting for Stock-Based Compensation

The Company has various stock-based compensation plans for its employees and outside directors and
accounts for stock-based compensation arrangements in accordance with the authoritative guidance, which
requires the Company to measure and record compensation expense in its consolidated financial statements using
a fair value method. See Note 7 for further information regarding the Company’s stock-based compensation
plans.

Net Income Per Share Attributable to Citrix Systems, Inc. Stockholders

Net income per share attributable to Citrix Systems, Inc. stockholders - basic is calculated by dividing
income available to stockholders by the weighted-average number of common shares outstanding during each
period. Net income per share attributable to Citrix Systems, Inc. stockholders - diluted is computed using the
weighted average number of common and dilutive common share equivalents outstanding during the period.
Dilutive common share equivalents consist of shares issuable upon the vesting or exercise of stock awards
(calculated using the treasury stock method) during the period they were outstanding. Certain shares under the
Company’s stock-based compensation programs were excluded from the computation of diluted earnings per
share due to their anti-dilutive effect for the respective periods in which they were outstanding. The
reconciliation of the numerator and denominator of the earnings per share calculation is presented in Note 15.

3. ACQUISITIONS

2010 Acquisitions

On September 7, 2010, the Company acquired all of the issued and outstanding securities of VMLogix, Inc.

(“VMLogix”), a privately held corporation headquartered in Santa Clara, California. VMLogix is a provider of
virtualization management software for private and public cloud computing systems. The total consideration for
this transaction was approximately $13.2 million, comprised of approximately $10.4 million in cash, net of cash
acquired, and approximately $2.8 million related to VMLogix liabilities settled in conjunction with the
acquisition. The source of funds for this transaction consisted of available cash. The Company recorded
approximately $7.7 million of goodwill, which is not deductible for tax purposes, and acquired $10.6 million in
assets including $7.5 million of identifiable intangible assets, of which $6.2 million is related to product related
intangible assets with a useful life of 5.0 years and $1.3 million is related to other intangible assets with a useful
life of 4.0 years. The Company assumed liabilities of approximately $5.1 million in conjunction with the
acquisition. In addition, the Company also assumed stock options for which the vesting period reset fully upon
the closing of the transaction. When these stock options vest, they will be exercisable for up to 47,784 shares of
the Company’s common stock. The Company has included the effect of this transaction in its results of
operations prospectively from the date of the acquisition, which effect was not material to its consolidated
results.

During the first quarter of 2010, the Company acquired two privately-held companies for a total cash
consideration of approximately $9.2 million, net of cash acquired. The Company recorded approximately $2.6
million of goodwill, which is not deductible for tax purposes, and acquired $9.4 million in assets including $7.1
million of identifiable intangible assets, of which $6.2 million is related to product related intangible assets with
a weighted-average useful life of 5.0 years and $0.9 million is related to other intangible assets with a weighted-
average useful life of 2.0 years. In addition, the Company assumed liabilities of approximately $2.8 million in
conjunction with the acquisitions. The Company has included the effects of these transactions in its results of
operations prospectively from the respective dates of the acquisitions, which effects were not material to its
consolidated results.

2008 Acquisition

In October 2008, the Company acquired all of the issued and outstanding securities of Vapps, Inc.

(“Vapps”), a privately held corporation headquartered in Hoboken, New Jersey. Vapps offers high quality audio
conferencing solutions to small and medium sized businesses and enterprise and service provider markets that
complement the Company’s online services. The total consideration for this transaction was approximately $29.7
million in cash, net of cash acquired, including $1.0 million in transaction costs. At the time of the acquisition, if
certain financial and operational milestones are achieved by the Vapps business, contingent consideration of up

F-18

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

to approximately $4.4 million may be earned over a three year period from the date of the acquisition. As of
December 31, 2010, $1.9 million and $1.2 million was earned in 2010 and 2009, respectively. The sources of
funds for this transaction consisted of available cash and investments. In addition, the Company assumed
unvested stock options upon the closing of the transaction, which will become exercisable (upon vesting) for
approximately 0.1 million shares of the Company’s common stock. Revenues from Vapps are included in the
Company’s Online Services revenue. In connection with the Vapps Acquisition, the Company allocated $21.8
million to goodwill, $8.2 million to product related technologies and $2.6 million to other intangible assets. The
goodwill related to the Vapps acquisition was allocated to the Company’s Online Services division and is not
deductible for tax purposes.

Netviewer AG Acquisition

In December 2010, the Company entered into an agreement to acquire all of the issued and outstanding

securities of Netviewer AG (“Netviewer”), a privately held European SaaS vendor in collaboration and IT
services. Netviewer will become part of the Company’s Online Services division and the acquisition will enable
the extension of its SaaS leadership in Europe. The acquisition closed in February 2011 and the total preliminary
consideration for this transaction was approximately $115.0 million and was payable in cash. In addition, in
connection with the acquisition the Company converted and assumed approximately 99,100 non-vested stock
units. Transaction costs associated with the acquisition are currently estimated at $2.5 million, of which the
Company expensed $2.0 million in 2010 and are included in general and administrative expense in the
accompanying consolidated statements of income for the year ended December 31, 2010.

In-process Research and Development

The fair values used in determining the purchase price allocation for certain intangible assets for the
Company’s acquisitions were based on estimated discounted future cash flows, royalty rates and historical data,
among other information. Purchased in-process research and development (“IPR&D”) of $1.1 million was
expensed immediately upon the closing of the acquisition of Vapps because it pertained to technology that was
not currently technologically feasible, meaning it had not reached the working model stage, did not contain all of
the major functions planned for the product, was not ready for initial customer testing and had no alternative
future use. The fair value assigned to IPR&D was determined using the income approach, which includes
estimating the revenue and expenses associated with a project’s sales cycle and by estimating the amount of
after-tax cash flows attributable to the projects. The future cash flows were discounted to present value utilizing
an appropriate risk-adjusted rate of return, which was 21%. The rate of return included a factor that takes into
account the uncertainty surrounding the successful development of the IPR&D.

In 2009, the Company adopted new accounting rules for acquisitions and future IPR&D will be capitalized.

No IPR&D was capitalized in 2010 and 2009.

The change in net unrealized gains (losses) on available-for-sale securities recorded in other comprehensive

income includes unrealized gains (losses) that arose from changes in market value of specifically identified
securities that were held during the period and gains (losses) that were previously unrealized, but have been
recognized in current period net income due to sales, as well as prepayments of available-for-sale investments
purchased at a premium. This reclassification has no effect on total comprehensive income or equity and was
immaterial for all periods presented.

The average remaining maturities of the Company’s short-term and long-term available-for-sale investments

at December 31, 2010 were approximately five months and seven years, respectively.

Realized Gains and Losses on Available-for-sale Investments

For the years ended December 31, 2010 and 2009, the Company had realized gains on the sales of

available-for-sale investments of $0.2 million and $0.6 million, respectively. For the years ended December 31,
2010 and 2009, the Company had realized losses on the sales of available-for-sale investments of $2.4 million
and $0.1 million, respectively. All realized gains and losses related to the sales of available-for-sale investments
are included in other (expense) income, net, in the accompanying consolidated statements of income.

The Company continues to monitor its overall investment portfolio and if the credit ratings of the issuers of

its investments deteriorate or if the issuers experience financial difficulty, including bankruptcy, the Company
may be required to make additional adjustments to the carrying value of the securities in its investment portfolio
and recognize additional impairment charges for declines in fair value that are determined to be other-than-
temporary.

Unrealized Losses on Available-for-sale Investments

The gross unrealized losses on the Company’s available-for-sale investments that are not deemed to be

other-than-temporarily impaired as of December 31, 2010 was $1.9 million compared to $6.0 million as of
December 31, 2009. This decrease was primarily due to a recovery in value of the Company’s investment issued
by AIG Matched Funding Corporation (the “AIG Capped Floater”) with a face value of $50.0 million, which
matures in September 2011. As of December 31, 2010, the unrealized loss related to the AIG Capped Floater was
$0.7 million, which is included in accumulated other comprehensive income (loss). As of the date of this report,

F-20

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

American International Group, Inc. (“AIG”) has not been reported to have defaulted on capital repayments to
holders of its recently matured debt. Because the Company does not intend to sell the AIG Capped Floater and it
is more likely than not that it will not be required to sell the security before the recovery of its amortized cost
basis, which may not occur until maturity, it does not consider the security to be other-than-temporarily impaired.

Trading Investments

The Company held municipal auction rate securities, the majority of which were triple-A rated, whose
underlying assets were generally student loans that were substantially backed by the federal government under
the Federal Family Education Loan Program through investment accounts managed by UBS Financial Services,
Inc. (“UBS”). The market for municipal auction rate securities in the Company’s portfolio began experiencing
auction failures in 2008. In November 2008, the Company formally accepted the terms of a settlement (the
“Settlement”) from UBS. Upon accepting the terms of the Settlement, the Company received an enforceable,
non-transferrable right (the “Put Option”) that enabled it to sell its auction rate securities back to UBS. On
June 30, 2010, the Company exercised the Put Option and sold all of its remaining investments in auction rate
securities back to UBS at par. During 2010, the Company realized a gain of $6.0 million related to the sale of its
investments in auction rate securities and a corresponding loss of $6.0 million related to the settlement of the Put
Option, both of which are included in other (expense) income, net, in the accompanying consolidated statements
of income.

Cost Method Investments

The Company held direct investments in privately-held companies of approximately $21.3 million and
$10.2 million as of December 31, 2010 and 2009, respectively, which are accounted for based on the cost method
and are included under other assets in the accompanying consolidated balance sheets. The Company periodically
reviews these investments for impairment.

5. FAIR VALUE MEASUREMENTS

The authoritative guidance defines fair value as an exit price, representing the amount that would either be

received to sell an asset or be paid to transfer a liability in an orderly transaction between market participants. As
such, fair value is a market-based measurement that should be determined based on assumptions that market
participants would use in pricing an asset or liability. As a basis for considering such assumptions, the guidance
establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

•

•

•

Level 1. Observable inputs such as quoted prices in active markets for identical assets or liabilities;

Level 2. Inputs, other than the quoted prices in active markets, that are observable either directly or
indirectly; and

Level 3. Unobservable inputs in which there is little or no market data, which require the reporting
entity to develop its own assumptions.

The Company measures its cash flow hedges, which are classified as prepaid expenses and other current
assets and accrued expenses and other current liabilities, at fair value based on indicative prices in active markets
and generally measures its investments in available-for-sale securities at fair value based on quoted prices in
active markets for identical securities.

As quoted prices in active markets were not available for the AIG Capped Floater, in order to measure it at
fair value, the Company used a discounted cash flow model. The Company then discounted those cash flows at a
rate reflecting the market risk inherent in holding an AIG security with a similar maturity as evidenced by pricing
in the markets. Since utilizing a discounted cash flow model required the Company to make assumptions that
were not directly or indirectly observable regarding the AIG Capped Floater’s fair value, accordingly it is a Level
3 valuation and is included in the table below.

7. EMPLOYEE STOCK-BASED COMPENSATION AND BENEFIT PLANS

Plans

The Company’s stock-based compensation program is a long-term retention program that is intended to
attract and reward talented employees and align stockholder and employee interests. As of December 31, 2010,
the Company had two stock-based compensation plans under which it was granting stock options and non-vested
stock units. The Company is currently granting stock-based awards from its Amended and Restated 2005 Equity
Incentive Plan (as amended, the “2005 Plan”) and its 2005 Employee Stock Purchase Plan (the “2005 ESPP”). In
connection with certain of the Company’s acquisitions, the Company has assumed several plans from acquired
companies. The Company’s Board of Directors has provided that no new awards will be granted under the
Company’s acquired stock plans. The Company’s superseded and expired stock plans include the Amended and
Restated 1995 Stock Plan, Second Amended and Restated 2000 Director and Officer Stock Option and Incentive
Plan, Second Amended and Restated 1995 Non-Employee Director Stock Option Plan and Third Amended and
Restated 1995 Employee Stock Purchase Plan. Awards previously granted under these plans and still outstanding
typically expire ten years from the date of grant and will continue to be subject to all the terms and conditions of
such plans, as applicable.

Under the terms of the 2005 Plan, the Company is authorized to grant incentive stock options (“ISOs”),

non-qualified stock options (“NSOs”), non-vested stock, non-vested stock units, stock appreciation rights
(“SARs”), and performance units and to make stock-based awards to full and part-time employees of the
Company and its subsidiaries or affiliates, where legally eligible to participate, as well as consultants and
non-employee directors of the Company. Currently, the 2005 Plan provides for the issuance of a maximum of
37,600,000 shares of common stock. Under the 2005 Plan, ISOs must be granted at exercise prices no less than
fair market value on the date of grant, except for ISOs granted to employees who own more than 10% of the
Company’s combined voting power, for which the exercise prices must be no less than 110% of the fair market
value at the date of grant. NSOs and SARs must be granted at no less than fair market value on the date of grant,
or in the case of SARs in tandem with options, at the exercise price of the related option. Non-vested stock
awards may be granted for such consideration in cash, other property or services, or a combination thereof, as
determined by the Company’s Compensation Committee of its Board of Directors. All stock-based awards, other
than the long-term incentive awards discussed below, are exercisable or issuable upon vesting. The Company’s
policy is to recognize compensation cost for awards with only service conditions and a graded vesting schedule
on a straight-line basis over the requisite service period for the entire award. As of December 31, 2010, there
were 26,225,760 shares of common stock reserved for issuance pursuant to the Company’s stock-based
compensation plans and the Company had authorization under its 2005 Plan to grant 13,208,874 additional stock-
based awards.

F-23

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Under the 2005 ESPP, all full-time and certain part-time employees of the Company are eligible to purchase

common stock of the Company twice per year at the end of a six-month payment period (a “Payment Period”).
During each Payment Period, eligible employees who so elect may authorize payroll deductions in an amount no
less than 1% nor greater than 10% of his or her base pay for each payroll period in the Payment Period. At the
end of each Payment Period, the accumulated deductions are used to purchase shares of common stock from the
Company up to a maximum of 12,000 shares for any one employee during a Payment Period. Shares are
purchased at a price equal to 85% of the fair market value of the Company’s common stock on the last business
day of a Payment Period. Employees who, after exercising their rights to purchase shares of common stock in the
2005 ESPP, would own shares representing 5% or more of the voting power of the Company’s common stock,
are ineligible to participate under the 2005 ESPP. The 2005 ESPP provides for the issuance of a maximum of
10,000,000 shares of common stock. As of December 31, 2010, 1,904,576 shares had been issued under the 2005
ESPP. The Company recorded stock-based compensation costs related to the 2005 ESPP of $2.8 million, $2.2
million and $2.3 million for the years ended December 31, 2010, 2009 and 2008, respectively.

Expense Information under the Authoritative Guidance

As required by the authoritative guidance, the Company estimates forfeitures of employee stock options and

recognizes compensation costs only for those awards expected to vest. Forfeiture rates are determined based on
historical experience. The Company also considers whether there have been any significant changes in facts and
circumstances that would affect its forfeiture rate quarterly. Estimated forfeitures are adjusted to actual forfeiture
experience as needed. The Company recorded stock-based compensation costs, related deferred tax assets and tax
benefits of $103.8 million, $31.1 million and $100.1 million, respectively, in 2010, $111.4 million, $32.8 million
and $36.2 million, respectively, in 2009 and $124.6 million, $34.9 million and $16.5 million, respectively, in
2008.

Stock Options

As part of the Company’s 2010 acquisitions, the Company assumed 54,967 options to purchase shares of its
common stock, all of which upon assumption were reset to have a five year life and vest over two to three years
from date of grant. Options granted pursuant to the 2005 Plan typically have a five year life and vest over three
years at a rate of 33.3% of the shares underlying the option one year from date of grant and at a rate of 2.78%
monthly thereafter. A summary of the status and activity of the Company’s fixed option awards is as follows:

million related to options for the years ended December 31, 2010, 2009 and 2008, respectively. As of
December 31, 2010, there was $69.6 million of total unrecognized compensation cost related to stock options.
That cost is expected to be recognized over a weighted-average period of 2.23 years. The total intrinsic value of
stock options exercised during 2010, 2009 and 2008 was $293.7 million, $97.7 million and $44.8 million,
respectively.

Stock Option Valuation Information under the Authoritative Guidance

The Company currently uses the Black-Scholes option pricing model to determine the fair value of its stock
options. The determination of the fair value of stock-based payment awards on the date of grant using an option-
pricing model is affected by the Company’s stock price, as well as assumptions regarding a number of complex
and subjective variables. These variables include the Company’s expected stock price, volatility over the term of
the awards, actual employee exercise behaviors, risk-free interest rate and expected dividends. For purposes of
valuing stock options, the Company determined the expected volatility factor by considering the implied
volatility in two-year market-traded options of the Company’s common stock based on third party volatility
quotes in accordance with the provisions of SAB No. 107, Share Based Payment. The Company’s decision to use
implied volatility was based upon the availability of actively traded options on the Company’s common stock
and its assessment that implied volatility is more representative of future stock price trends than historical
volatility. The approximate risk free interest rate was based on the implied yield available on U.S. Treasury zero-
coupon issues with remaining terms equivalent to the Company’s expected term on its options. The expected
term of the Company’s stock options was based on the historical employee exercise patterns. The Company also
periodically analyzes its historical pattern of option exercises based on certain demographic characteristics and
determined that there were no meaningful differences in option exercise activity based on the demographic
characteristics. The Company does not intend to pay dividends on its common stock in the foreseeable future.
Accordingly, the Company used a dividend yield of zero in its option pricing model. The weighted average fair

For the years ended December 31, 2010, 2009 and 2008, the Company recognized stock-based

compensation expense of $13.2 million, $16.6 million and $17.2 million, respectively, related to non-vested
stock. The fair value of non-vested stock released in 2010, 2009 and 2008 was $13.7 million, $16.6 million and
$11.0 million, respectively. As of December 31, 2010, there was no unrecognized compensation cost related to
non-vested stock.

Non-vested Stock Units

Annually, the Company awards vice presidents and senior executives non-vested performance stock units
from the 2005 Plan. The number of non-vested stock units underlying each award is determined one year after
the date of the award and is based on achievement of a specific corporate financial performance goal. If the
performance goal is less than 90% attained, then no non-vested stock units will be issued pursuant to the
authorized award. For performance at and above 90%, the number of non-vested stock units issued is based on a
graduated slope, with the maximum number of non-vested stock units issuable pursuant to the award capped at
125% of the base number of non-vested stock units set forth in the executive’s award agreement. The Company
is required to estimate the attainment that will be achieved related to the defined performance goals and the
number of non-vested stock units that will ultimately be awarded in order to recognize compensation expense
over the vesting period. If the performance goal is met, the non-vested stock units vest 33.33% on each
anniversary subsequent to the date of the award. Each non-vested stock unit, upon vesting, represents the right to
receive one share of the Company’s common stock. If the performance goals are not met, no compensation cost
will ultimately be recognized in that period and any previously recognized compensation cost will be reversed.
During 2010 and 2009, the performance goal was achieved within the range of the graduated slope and there was
no material adjustment to compensation cost related to non-vested stock units granted to executives.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company also awards vice presidents, senior executives and certain other employees non-vested stock

units from the 2005 Plan that vest based on service. These non-vested stock units vest 33.33% on each
anniversary subsequent to the date of the award. Each non-vested stock unit, upon vesting, will represent the
right to receive one share of the Company’s common stock. In addition, the Company awards non-vested stock
units to all of its non-employee directors. These units vest monthly in 12 equal installments based on service and,
upon vesting, each stock unit represents the right to receive one share of the Company’s common stock.

For the years ended December 31, 2010, 2009 and 2008, the Company recognized stock-based

compensation expense of $19.3 million, $13.1 million and $13.6 million, respectively, related to non-vested
stock units. The fair value of the non-vested stock units released in 2010, 2009, 2008 was $11.6 million, $12.1
million and $7.5 million, respectively. As of December 31, 2010, there was $30.7 million of total unrecognized
compensation cost related to non-vested stock units. That cost is expected to be recognized over a weighted-
average period of 2.22 years.

Long-term Incentive Plan

In May 2009, the Company granted certain senior level executives restricted stock unit awards that vest
based on market and service conditions as part of a long-term incentive plan. The number of restricted stock units
underlying each award is determined at the end of a three-year performance period ending December 31, 2011. In
order to vest, the Company’s stock price must appreciate by at least ten percent by the end of the performance
period. If the Company’s stock appreciation is at least ten percent, then the percentage of the restricted stock
units that will vest will be determined by comparing the Company’s stock price appreciation to the appreciation
of the weighted average of two stock market indices comprised of the Standard & Poor’s 500 Index (the “S&P
500”), which has been assigned a two-thirds weighting, and the iShares Standard & Poor’s North America
Technology Index (the “IGM”), which has been assigned a one-third weighting. Based on the level of
performance, up to 200% of the award may vest. After vesting, the shares underlying the award will be issued at
the earliest of six months and one day after the participant’s separation from the Company (other than
termination for cause), the participant’s death, or the effective date of a change in control of the Company. In the
event of a change in control of the Company prior to the end of the performance period, the payout of any award
is limited to a prorated portion of such award based upon a performance assessment prior to the change in control
date.

The market condition requirements are reflected in the grant date fair value of the award, and the

compensation expense for the award will be recognized assuming that the requisite service is rendered regardless
of whether the market conditions are achieved. The grant date fair value of the restricted stock unit awards was
determined through the use of a Monte Carlo simulation model, which utilizes multiple input variables that
determine the probability of satisfying the market condition requirements applicable to each award.

For the years ended December 31, 2010 and 2009, the Company recognized stock-based compensation
expense of $1.5 million and $0.9 million, respectively, related to restricted stock units. As of December 31, 2010,
there was $1.9 million of total unrecognized compensation cost related to restricted stock units. The
unrecognized cost is expected to be recognized over 1.08 years.

Benefit Plan

The Company maintains a 401(k) benefit plan allowing eligible U.S.-based employees to contribute up to
60% of their annual compensation, limited to an annual maximum amount as set periodically by the IRS. The
Company, at its discretion, may contribute up to $0.50 for each dollar of employee contribution. The Company’s
total matching contribution to an employee is typically made at 3% of the employee’s annual compensation. The
Company’s matching contributions were $8.0 million, $7.2 million and $7.3 million in 2010, 2009 and 2008,
respectively. The Company’s contributions vest over a four-year period at 25% per year.

8. CAPITAL STOCK

Stock Repurchase Programs

The Company’s Board of Directors authorized an ongoing stock repurchase program with a total repurchase

authority granted to the Company of $2.5 billion. The Company may use the approved dollar authority to
repurchase stock at any time until the approved amount is exhausted. The objective of the Company’s stock
repurchase program is to improve stockholders’ returns. At December 31, 2010, approximately $120.3 million
was available to repurchase common stock pursuant to the stock repurchase program. All shares repurchased are
recorded as treasury stock. A portion of the funds used to repurchase stock over the course of the program was
provided by proceeds from employee stock option exercises and the related tax benefit.

The Company is authorized to make open market purchases of its common stock using general corporate

funds. Additionally, from time to time, the Company enters into structured stock repurchase arrangements with
large financial institutions using general corporate funds in order to lower the average cost to acquire shares.
These programs include terms that require the Company to make up-front payments to the counterparty financial
institution and result in the receipt of stock during or at the end of the term of the agreement or the receipt of
either stock or cash at the maturity of the agreement, depending on market conditions.

During the year ended December 31, 2010, the Company expended approximately $434.8 million on open
market purchases, repurchasing 8,157,400 shares of outstanding common stock at an average price of $53.31. In
addition, during the third quarter of 2010, the Company made an up-front payment of $15.0 million to a financial
institution related to a structured stock repurchase agreement. At the maturity of the agreement in the fourth

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

quarter of 2010, the Company received $16.1 million in cash, including premiums, and did not take delivery of
any shares related to the agreement due to market conditions. As of December 31, 2010, the Company did not
have any prepaid notional amounts outstanding relating to its structured stock repurchase programs.

During the year ended December 31, 2009, the Company expended approximately $214.9 million on open

market purchases, repurchasing 6,475,830 shares of outstanding common stock at an average price of $33.19. As
of December 31, 2009, the Company did not have any prepaid notional amounts outstanding under its structured
stock repurchase programs and during the year it did not make any up-front payments to financial institutions
related to structured stock repurchase agreements.

During the year ended December 31, 2008, the Company took delivery of 4,406,757 shares at an average

price of $33.30 per share from its structured repurchase agreements and it expended approximately $197.6
million on open market purchases, repurchasing 6,451,591 shares of outstanding common stock at an average
price of $30.63. As of December 31, 2008, the Company did not have any prepaid notional amounts outstanding
under its structured stock repurchase programs.

Shares for Tax Withholding

During the year ended December 31, 2010, the Company withheld 123,489 shares from vested stock units

totaling $6.3 million to satisfy tax withholding obligations that arose on the vesting of shares of stock units.
These shares are reflected as treasury stock in the Company’s consolidated balance sheets and the related cash
outlays reduce the Company’s total stock repurchase authority.

During the year ended December 31, 2009, the Company withheld 46,732 shares from vested stock units

totaling $1.8 million to satisfy tax withholding obligations that arose on the vesting of shares of stock units.
These shares are reflected as treasury stock in the Company’s consolidated balance sheets and the related cash
outlays reduce the Company’s total stock repurchase authority.

Preferred Stock

The Company is authorized to issue 5,000,000 shares of preferred stock, $0.01 par value per share. No

shares of such preferred stock were issued and outstanding at December 31, 2010 or 2009.

9. CREDIT FACILITY

Effective on August 9, 2005, the Company entered into a revolving credit facility (the “Credit Facility”)

with a group of financial institutions (the “Lenders”). Effective September 27, 2006, the Company entered into
an amendment and restatement of its Credit Facility (the “Amendment”). The Amendment decreased the overall
range of interest rates the Company must pay on amounts outstanding on the Credit Facility and lowered the
facility fee. In addition, the Amendment extended the term of the Credit Facility. The Credit Facility, as
amended, allows the Company to increase the revolving credit commitment up to a maximum aggregate
revolving credit commitment of $175.0 million. The Credit Facility, as amended, will expire on September 27,
2011 and it currently provides for a revolving line of credit in the aggregate amount of $100.0 million, subject to
continued covenant compliance. A portion of the revolving line of credit (i) in the aggregate amount of $25.0
million may be available for issuances of letters of credit and (ii) in the aggregate amount of $15.0 million may
be available for swing line loans. The Credit Facility, as amended, currently bears interest at the London
Interbank Offered Rate (“LIBOR”) plus 0.32% and adjusts in the range of 0.32% to 0.80% above LIBOR based
on the level of the Company’s total debt and its adjusted earnings before interest, taxes, depreciation and

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

amortization (“EBITDA”) as defined in the agreement. In addition, the Company is required to pay a quarterly
facility fee ranging from 0.08% to 0.20% based on the aggregate amount available under the Credit Facility, as
amended, and the level of the Company’s total debt and its adjusted EBITDA. Borrowings under the Credit
Facility, as amended, are guaranteed by the Company and certain of the Company’s U.S. and foreign
subsidiaries, which guarantees are secured by a pledge of shares of certain foreign subsidiaries. During the year
ended December 31, 2010, no borrowings were made under the Credit Facility, as amended, and as of
December 31, 2010, there were no amounts outstanding under the Credit Facility, as amended.

The Credit Facility, as amended, contains customary default provisions, and the Company must comply with

various financial and non-financial covenants. The financial covenants consist of a minimum interest coverage
ratio and a maximum consolidated leverage ratio. The primary non-financial covenants contain certain limits on
the Company’s ability to pay dividends, conduct certain mergers or acquisitions, make certain investments and
loans, incur future indebtedness or liens, alter the Company’s capital structure or sell stock or assets. As of
December 31, 2010, the Company was in compliance with all covenants of the Credit Facility.

10. COMMITMENTS AND CONTINGENCIES

Leases

The Company leases certain office space and equipment under various operating leases. In addition to rent,
the leases require the Company to pay for taxes, insurance, maintenance and other operating expenses. Certain of
these leases contain stated escalation clauses while others contain renewal options. The Company recognizes rent
expense on a straight-line basis over the term of the lease, excluding renewal periods, unless renewal of the lease
is reasonably assured.

Rental expense for the years ended December 31, 2010, 2009 and 2008 totaled approximately $54.6 million,
$51.3 million and $46.0 million, respectively. Sublease income for the years ended December 31, 2010, 2009 and
2008 was approximately $0.2 million, $0.1 million and $0.8 million, respectively. Lease commitments under
non-cancelable operating leases with initial or remaining terms in excess of one year and sublease income
associated with non-cancelable subleases, are as follows:

The Company has operating lease obligations through 2018 related to two properties that are not utilized. At
December 31, 2010, the total remaining obligation on these lease obligations was approximately $6.4 million, of
which $2.9 million was accrued as of December 31, 2010, and is reflected in accrued expenses and other current
liabilities and other liabilities in the accompanying consolidated balance sheets. In calculating these accruals, the
Company made estimates, based on market information, including the estimated vacancy periods and sublease
rates and opportunities. The Company periodically re-evaluates its estimates related to the vacant facilities.

Legal Matters

Due to the nature of the Company’s business, it is subject to patent infringement claims, including current
suits against it or one or more of its wholly-owned subsidiaries alleging infringement by various Citrix products
and services. The Company believes that it has meritorious defenses to the allegations made in its pending cases
and intends to vigorously defend these lawsuits; however, it is unable currently to determine the ultimate
outcome of these or similar matters or the potential exposure to loss, if any.

In addition, the Company is a defendant in various litigation matters generally arising out of the normal
course of business. Although it is difficult to predict the ultimate outcomes of these cases, the Company believes
that the ultimate outcomes will not materially affect its business, financial position, results of operations or cash
flows.

Guarantees

The authoritative guidance requires certain guarantees to be recorded at fair value and requires a guarantor
to make disclosures, even when the likelihood of making any payments under the guarantee is remote. For those
guarantees and indemnifications that do not fall within the initial recognition and measurement requirements of
the authoritative guidance, the Company must continue to monitor the conditions that are subject to the
guarantees and indemnifications, as required under existing generally accepted accounting principles, to identify
if a loss has been incurred. If the Company determines that it is probable that a loss has been incurred, any such
estimable loss would be recognized. The initial recognition and measurement requirements do not apply to the
provisions contained in the majority of the Company’s software license agreements that indemnify licensees of
the Company’s software from damages and costs resulting from claims alleging that the Company’s software
infringes the intellectual property rights of a third party. The Company has not made payments pursuant to these
provisions. The Company has not identified any losses that are probable under these provisions and, accordingly,
the Company has not recorded a liability related to these indemnification provisions.

Purchase Obligations

The Company has agreements with suppliers to purchase inventory and estimates its non-cancelable
obligations under these agreements for the fiscal year ended December 31, 2011 to be approximately $9.7
million. The Company also has contingent obligations to purchase inventory for the fiscal year ended
December 31, 2011, which are based on amount of usage, of approximately $8.4 million. The Company did not
have any obligations beyond December 31, 2011.

The authoritative guidance requires a valuation allowance to reduce the deferred tax assets reported if it is

not more likely than not that some portion or all of the deferred tax assets will be realized. At December 31,
2010, the Company determined that a $14.0 million valuation allowance relating to deferred tax assets for net
operating losses was necessary.

The Company does not expect to remit earnings from its foreign subsidiaries. Undistributed earnings of the

Company’s foreign subsidiaries amounted to approximately $1,070.1 million at December 31, 2010. Those
earnings are considered to be permanently reinvested and, accordingly, no U.S. federal and state income taxes
have been provided thereon. Upon distribution of those earnings in the form of dividends or otherwise, the
Company could be subject to both U.S. income taxes (subject to an adjustment for foreign tax credits) and
withholding taxes payable to various foreign countries.

At December 31, 2010, the Company had $95.1 million of remaining net operating loss carry forwards in
the United States from acquisitions. The utilization of these net operating loss carry forwards are limited in any

Company had $8.8 million of remaining net operating loss carry forwards in foreign jurisdictions that do not

At December 31, 2010, the Company had research and development tax credit carry forwards of
approximately $64.4 million that begin to expire in 2024 and a foreign tax credit carry-forward in a foreign

The Company does not expect its unrecognized tax benefits to change significantly over the next 12 months.

At December 31, 2010, there was $1.5 million related to tax positions for which the ultimate deductibility is
highly certain but for which there is uncertainty about the timing of such deductibility. Because of the impact of
deferred tax accounting, other than interest and penalties, the disallowance of the shorter deductibility period
would not affect the annual effective tax rate but would accelerate the payment or receipt of cash to an earlier
period.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

The Company recognizes interest accrued related to unrecognized tax benefits and penalties in income tax
expense. During the year ended December 31, 2010, the Company recognized $0.1 million of expense related to
interest and penalties. The Company has approximately $1.3 million for the payment of interest and penalties
accrued at December 31, 2010.

In June 2010, the Company reached a settlement in principle with the Internal Revenue Service (“IRS”)

regarding certain previously disclosed income tax deficiencies asserted in a Revenue Agent’s Report (the
“RAR”). Under the terms of the settlement in principle, the Company would agree to an assessment of income
tax deficiencies in full settlement of all open claims under the RAR and would resolve with finality for future
years all of the transfer pricing issues raised in the RAR. Based on this, the Company incurred a charge of $13.1
million in 2010 in accordance with the authoritative guidance. Among other things, the authoritative guidance
requires application of a “more likely than not” threshold to the recognition and non-recognition of tax positions.
It further requires that a change in management judgment related to prior years’ tax positions be recognized in
the quarter of such change.

The final settlement requires the finalization of tax deficiency calculations with the IRS and a written

agreement signed by the IRS. This process could take several more months to complete. There can be no
assurances that a final written agreement will be obtained or that this matter will otherwise be resolved in the
Company’s favor. An adverse outcome of this matter could have a material adverse effect on the Company’s
results of operations and financial condition.

12. SEGMENT INFORMATION AND SIGNIFICANT CUSTOMERS

During the first quarter of 2010, the Company changed how it measures profitability internally, develops its
annual plan and allocates its resources from a geography-based approach (which included the Americas, EMEA,
Asia-Pacific and the Company’s Online Services division), to a product division-based approach. This change
reflects how the Company markets and sells its products. Accordingly, the Company has revised its reportable
segments to reflect the way its chief operating decision maker (“CODM”) is currently managing and viewing the
business. In addition, previously reported segment results have been restated to conform to the 2010 presentation.
The Company’s revenues are derived from sales of its Enterprise division products which include its Desktop
Solutions, Datacenter and Cloud Solutions and related technical services and from sales of its Online Services
division’s web collaboration, remote access and support services. The Enterprise division and the Online
Services division constitute the Company’s two reportable segments.

The Company does not engage in intercompany revenue transfers between segments. The Company’s
CODM evaluates the Company’s performance based primarily on profitability from its Enterprise division
products and Online Services division services. Segment profit for each segment includes certain research and
development, sales, marketing, general and administrative expenses directly attributable to the segment as well as
other corporate costs allocated to the segment and excludes certain expenses that are managed outside of the
reportable segments. Costs excluded from segment profit primarily consist of certain restructuring charges,
stock-based compensation costs, amortization of product related technology, amortization of other intangible
assets, in-process research and development, net interest and other (expense) income, net. Accounting policies of
the Company’s segments are the same as its consolidated accounting policies. In addition, the Company will
evaluate goodwill for impairment at the operating segment level, which represents its reporting units.

In fiscal years 2010, 2009 and 2008, one distributor, Ingram Micro, accounted for 17%, 14% and 12%,
respectively, of the Company’s total net revenues. The Company’s distributor arrangements with Ingram Micro
consist of several non-exclusive, independently negotiated agreements with its subsidiaries, each of which cover
different countries or regions. Each of these agreements is separately negotiated and is independent of any other
contract (such as a master distribution agreement). None of these contracts were individually responsible for over
10% of the Company’s total net revenues in each of the last three fiscal years. In fiscal years 2010, 2009 and

14. DERIVATIVE FINANCIAL INSTRUMENTS

Cash Flow Hedges

As of December 31, 2010, the Company’s derivative assets and liabilities resulted from cash flow hedges
related to its forecasted operating expenses transacted in local currencies. A substantial portion of the Company’s
overseas expenses are and will continue to be transacted in local currencies. To protect against fluctuations in
operating expenses and the volatility of future cash flows caused by changes in currency exchange rates, the
Company has established a program that uses foreign exchange forward contracts to hedge its exposure to these
potential changes. The terms of these instruments, and the hedged transactions to which they relate, generally do
not exceed 12 months and the maximum term is 18 months.

Generally, when the dollar is weak, foreign currency denominated expenses will be higher, and these higher
expenses will be partially offset by the gains realized from the Company’s hedging contracts. Conversely, if the
dollar is strong, foreign currency denominated expenses will be lower. These lower expenses will in turn be
partially offset by the losses incurred from the Company’s hedging contracts. The change in the derivative
component in accumulated other comprehensive income (loss) includes unrealized gains or losses that arose from
changes in market value of the effective portion of derivatives that were held during the period, and gains or
losses that were previously unrealized but have been recognized in the same line item as the forecasted
transaction in current period net income due to termination or maturities of derivative contracts. This
reclassification has no effect on total comprehensive income or equity.

The total cumulative unrealized gain on cash flow derivative instruments was $6.1 million and $4.3 million
at December 31, 2010 and 2009, respectively, and is included in accumulated other comprehensive income (loss)
in the accompanying consolidated balance sheets. The net unrealized gain as of December 31, 2010 is expected
to be recognized in income over the next twelve months at the same time the hedged items are recognized in
income.

As of December 31, 2010, the Company had the following net notional foreign currency forward contracts

outstanding (in thousands):

CITRIX SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

A substantial portion of the Company’s overseas assets and liabilities are and will continue to be
denominated in local currencies. To protect against fluctuations in earnings caused by changes in currency
exchange rates when remeasuring the Company’s balance sheet, it utilizes foreign exchange forward contracts to
hedge its exposure to this potential volatility. There were no assets or liabilities related to derivatives not
designated as hedges outstanding as of December 31, 2010 and 2009.

16. RECENT ACCOUNTING PRONOUNCEMENTS

In September 2009, FASB amended the Accounting Standards Codification (“ASC”) as summarized in
Accounting Standards Update (“ASU”) 2009-14, Software (Topic 985): Certain Revenue Arrangements That
Include Software Elements, and ASU 2009-13, Revenue Recognition (Topic 605): Multiple-Deliverable Revenue
Arrangements. As summarized in ASU 2009-14, ASC Topic 985 has been amended to remove from the scope of
industry specific revenue accounting guidance for software and software related transactions, tangible products
containing software components and non-software components that function together to deliver the product’s
essential functionality. As summarized in ASU 2009-13, ASC Topic 605 has been amended: (1) to provide
updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be
separated, and the consideration allocated; (2) to require an entity to allocate revenue in an arrangement using
estimated selling prices of deliverables if a vendor does not have VSOE or third-party evidence of selling price;
and (3) to eliminate the use of the residual method and require an entity to allocate revenue using the relative
selling price method. The accounting changes summarized in ASU 2009-14 and ASU 2009-13 are both effective
for the Company’s fiscal year beginning on January 1, 2011. The Company plans to adopt the standards on a
prospective basis and anticipates an immaterial impact upon adoption.

Information Concerning Non-GAAP Financial Measures Used in This Annual Report (Unaudited)

GAAP diluted earnings per share for the twelve months ended December 31, 2010 was $1.46. GAAP diluted earnings per 
share for the twelve months ended December 31, 2009 was $1.03.Non-GAAP net income and earnings per share for both 
periods excludes the effects of the amortization of intangible assets primarily related to business combinations, stock-based 
compensation  expenses,  charges  recorded  in  connection  with  the  restructuring  program  that  the  company  implemented  in 
January 2009, and the tax effects related to those items.

GAAP operating margin for the twelve months ended December 31, 2010 was 17.1%. GAAP operating margin for the twelve 
months  ended  December  31,  2009  was  11.1%.  Non-GAAP  operating  margin  for  both  periods  excludes  the  effects  of  the 
amortization of intangible assets primarily related to business combinations, stock-based compensation expenses and charges 
recorded in connection with the restructuring program that the company implemented in January 2009.

The  following  table  shows  the  non-GAAP  fi nancial  measures  used  in  this  Annual  Report  reconciled  to  the  most  directly

Pursuant to the requirements of Regulation G, Citrix Systems, Inc. (the “Company”) has provided a reconciliation of each non-GAAP
fi nancial measure used in this 2010 Annual Report to the most directly comparable GAAP fi nancial measure. These measures differ 
from  GAAP  in  that  they  exclude  amortization  primarily  related  to  business  combinations,  stock-based  compensation  expenses, 
charges associated with the Company’s 2009 restructuring program, and the related tax effect of those items. The Company’s basis
for these adjustments is described below.

Management uses these non-GAAP measures for internal reporting and forecasting purposes, when publicly providing its business 
outlook, to evaluate the Company’s performance and to evaluate and compensate the Company’s executives. The Company has 
provided these non-GAAP fi nancial measures in addition to GAAP fi nancial results because it believes that these non-GAAP fi nancial 
measures  provide  useful  information  to  certain  investors  and  fi nancial  analysts  for  comparison  across  accounting  periods  not 
infl uenced by certain non-cash items that are not used by management when evaluating the Company’s historical and prospective 
fi nancial performance. In addition, the Company has historically provided this or similar information and understands that some 
investors and fi nancial analysts fi nd this information helpful in analyzing the Company’s gross margins, operating expenses and net 
income and comparing the Company’s fi nancial performance to that of its peer companies and competitors.

Management  typically  excludes  the  amounts  described  above  when  evaluating  the  Company’s  operating  performance  and 
believes that the resulting non-GAAP measures are useful to investors and fi nancial analysts in assessing the Company’s operating 
performance due to the following factors:

• The Company does not acquire businesses on a predictable cycle. The Company, therefore, believes that the presentation 
of non-GAAP measures that adjust for the impact of amortization and certain stock-based compensation expenses and the 
related  tax  effects  that  are  primarily  related  to  business  combinations  provide  investors  and  fi nancial  analysts  with  a 
consistent basis for comparison across accounting periods; and, therefore, are useful to investors and fi nancial analysts in 
helping them to better understand the Company’s operating results and underlying operational trends.

• Amortization costs and the related tax effects are fi xed at the time of an acquisition, are then amortized over a period of 
several years after the acquisition and generally cannot be changed or infl uenced by management after the acquisition.

• Although  stock-based  compensation  is  an  important  aspect  of  the  compensation  of  the  Company’s  employees  and 
executives, stock-based compensation expense is generally fi xed at the time of grant, then amortized over a period of 
several years after the grant of the stock-based instrument, and generally cannot be changed or infl uenced by management 
after the grant.

• The charges incurred in conjunction with the Company’s restructuring program, which relate to reductions in headcount 
and exit costs associated with consolidating certain facilities, are not anticipated to be ongoing costs; and, thus, are outside
of the normal operations of the Company’s business.  The Company, therefore, believes that the exclusion of these charges 
will better help investors and fi nancial analysts understand the Company’s operating results and underlying operational 
trends as compared to prior periods.

These non-GAAP fi nancial measures are not prepared in accordance with accounting principles generally accepted in the United 
States  (“GAAP”)  and  may  differ  from  the  non-GAAP  information  used  by  other  companies.  There  are  signifi cant  limitations 
associated with the use of non-GAAP fi nancial measures. The additional non-GAAP fi nancial information presented here should be 
considered in conjunction with, and not as a substitute for or superior to, the fi nancial information presented in accordance with 
GAAP (such as net income and earnings per share) and should not be considered measures of the Company’s liquidity. Furthermore,
the Company in the future may exclude amortization, additional charges related to its restructuring program and the related tax
effects from fi nancial measures that it releases, and the Company expects to continue to incur stock-based compensation expenses.
