Overview
Riverbed® has developed an innovative and comprehensive solution to the fundamental problems of wide-area distributed computing. Historically, computing within an organization across wide area networks (WANs) has been plagued by poor performance, IT complexity and high cost. Our Steelhead® products enable our customers to improve the performance of their applications and access to their data across WANs, typically increasing transmission speeds by 5 to 50 times and in some cases by up to 100 times. Our products also offer the ability to simplify IT infrastructure and realize significant capital and operational cost savings. Our goal is to establish our solution as the preeminent performance and efficiency standard for organizations relying on wide-area distributed computing. We believe our products and services can provide significant benefits in millions of locations worldwide.
A common misconception is that increasing or optimizing bandwidth alone can adequately reduce the inefficiencies and performance problems inherent in wide-area distributed computing. Increasing or optimizing bandwidth may allow an organization to increase the amount of data that can traverse a WAN at a given point in time. However, WAN performance problems resulting from the distance between locations across a WAN and resulting from network and application protocol inefficiencies are not addressed by increasing or optimizing bandwidth alone. Inadequate bandwidth is only one of three inter-related causes of these performance problems. We believe that these problems can best be solved by simultaneously addressing all three inter-related root causes: software application protocol inefficiencies, transport network protocol inefficiencies and insufficient or unavailable bandwidth.
Unlike alternative approaches, our Steelhead products simultaneously address these root causes across a broad range of applications. Our products utilize our proprietary software to improve the performance of applications and access to data over distance by reducing:
| Ÿ | application protocol inefficiencies through our proprietary Application Streamlining techniques; |
| Ÿ | network protocol inefficiencies through our proprietary Transport Streamlining techniques; and |
| Ÿ | bandwidth requirements through our proprietary Data Streamlining techniques and data compression. |

Table of Contents
Our Steelhead products are used at both ends of a WAN connection and are designed to be more easily and transparently integrated into existing networks than alternative products. Our products address a broad range of widely used software applications, are scalable across networks of all sizes and address the wide-area distributed computing needs of every major industry.
We were founded in May 2002. Prior to the first commercial shipments of our products in May 2004, our activities were primarily focused on research and development of a comprehensive Wide-area Data Services (WDS) solution for organizations relying on wide-area distributed computing, development of a customer and partner support program to support our product offerings and the hiring of the personnel needed to sell, market and support our products and services. Since that time, our products have been sold to more than 3,500 customers worldwide, from large global organizations with hundreds or thousands of locations to smaller organizations. We sell our products and support directly through our sales force and indirectly through distribution partners, including value-added distributors, value-added resellers (VARs), Systems Integrators and Service Providers. We operate internationally primarily through a number of wholly owned subsidiaries that are designed primarily to support our sales, marketing and support activities outside the United States.
We have achieved broad industry recognition for our innovative technology:The Wall Street Journal selected our Steelhead appliances as a winner of one of its “2005 Technology Innovation Awards.”Network Computing Magazine presented us with its “Well-Connected Award” for Remote Office Solutions in 2006,InfoWorld magazine presented us with a “Technology of the Year” award in 2005, 2006, 2007 and 2008, and in 2006 and 2007, Gartner positioned us in the Leaders’ Quadrant in the “WAN Optimization Controller (WOC) Magic Quadrant.” This report positions vendors in one of four quadrants based on the companies’ vision and ability to execute on that vision.
Industry Background
We believe there are over four million remote offices of U.S. based companies alone. We also believe millions of remote computing locations exist for companies based outside the U.S. Many of these locations represent potential sites for our products.
The WDS market provides global access to data and applications across WANs with local area network (LAN)-like performance. The WDS market is large and growing. The key drivers of demand in this market are the increasingly geographically distributed nature of organizations and employees, the growing business dependence on application performance and real-time access to data and the increasing desirability of consolidation of IT resources to achieve compelling cost, management and data protection benefits.
Increasingly Distributed Organizations and Workforces
Organizations are becoming more geographically distributed, placing operations closer to customers and partners to improve efficiency and responsiveness. Businesses are becoming more global by expanding into new markets, migrating manufacturing facilities to lower-cost locations and outsourcing certain business processes. In addition, mergers, acquisitions, partnerships and joint ventures continue to expand the geographic scope of existing enterprises.
Organizations are Increasingly Dependent on Timely Access to Critical Data and Applications
Application performance and effective access to data are critical to executing, maintaining and expanding business operations. Employees are increasingly dependent on a wide array of software applications to perform their jobs effectively, such as e-mail, document management, enterprise resource planning and customer relationship management.

Benefits of IT Infrastructure Consolidation
As organizations have become more geographically distributed, installing and managing IT infrastructure has become increasingly costly and complex. Accordingly, IT managers often seek to consolidate IT infrastructure resources into headquarters or centralized datacenter locations, which can provide a number of benefits, including:
| Ÿ | reduction in capital costs as IT infrastructure resources (file servers, e-mail servers, web servers, application servers, back-up systems and databases) are consolidated and shared within an organization; |
| Ÿ | reduction in IT support costs as fewer personnel are required to manage more centralized data and applications; |
| Ÿ | more efficient and reliable data back-up and recovery and application and database administration by managing these processes from a central point of control; |
| Ÿ | improved data protection as consolidated IT infrastructure resources are less vulnerable to theft, loss and misuse; and |
| Ÿ | enhanced ability to implement internal controls and comply with other regulatory requirements as centralized data and applications are easier to monitor, store and access. |
Despite these benefits, many organizations have foregone or delayed consolidation projects because of performance problems.
Wide-Area Distributed Computing Challenges
Technological advances in computing, networking, semiconductor and storage technologies have improved users’ ability to access data and use applications rapidly across their LANs and store enormous amounts of information economically. However, these same applications and storage technologies, which were often designed to operate optimally on LANs, perform slowly across WANs and frequently exhibit the following performance challenges:
| Ÿ | delays in accessing, saving and transferring files; |
| Ÿ | slow execution of critical software application functions; |
| Ÿ | incomplete or inconsistent back-up and recovery of sensitive data; and |
| Ÿ | loss of worker productivity and increased end-user frustration. |
Although many companies have attempted to solve these problems solely by adding bandwidth, we believe these performance problems can best be solved by addressing not only bandwidth challenges but also, and usually more importantly, the effects of latency and protocol chattiness:
| Ÿ | Latency and protocol chattiness — “Latency” is the amount of time it takes data to travel distances across a WAN. “Chattiness” refers to the numerous interactions between clients and servers that are often required by applications or network transport protocols to complete an operation or transfer data. When combined in geographically distributed computing environments, latency and chattiness can result in dramatically slower performance. For example, a simple request to open a file may require hundreds if not thousands of sequential round-trip interactions that, when aggregated, can result in substantial delays. This problem arises from two distinct sources: |
| – | Application protocol chattiness — Many business applications were designed for optimal use within LAN environments and employ unique communications procedures that cause high chattiness, resulting in slow performance for the end-user when transmitted over a WAN; and |
5
Table of Contents
| – | Network protocol chattiness — Transmission Control Protocol (TCP), the underlying transport protocol for most WAN traffic, divides data into relatively small packets that are sent sequentially across the WAN, and require return acknowledgement from the recipient. These numerous round trips across the WAN can result in slow performance for the end-user. |
| Ÿ | Bandwidth limitations — Bandwidth is defined as the amount of data that can traverse a network in a given amount of time and is typically measured in megabits per second (Mbps). While most organizations’ LANs typically operate at 100 or 1,000 Mbps, their remote office WAN connections typically operate at 2 Mbps or less. This often results in WAN congestion and poor application and data services performance. In addition, WAN outages limit the effectiveness of workers who are dependent on remote access to data and applications. |
Limitations of Alternative Approaches
Historically, organizations have implemented partial solutions in attempting to improve the performance of wide-area distributed computing, including:
Additional Investment in Bandwidth and IT Infrastructure Resources
| Ÿ | Bandwidth— Organizations often attempt to improve application performance by making costly investments in more bandwidth. While additional bandwidth may reduce network congestion, no amount of bandwidth can address performance issues caused by high latency and application and network protocol chattiness; and |
| Ÿ | IT infrastructure resources — Deploying additional IT infrastructure resources at remote locations can increase selected application and data services performance. However, this approach is expensive, complex to manage and increases the risks of data inconsistency and compromised security. |
Deployment of Point Products
Our competitors have designed products that fail to address all of the root causes of wide-area distributed computing problems for a broad range of applications. Such products, which we refer to as point products, include:
| Ÿ | Caching — Cache-based architectures are application specific, and accordingly only improve the performance of applications for which they are written. For example, wide area file services (WAFS) approaches only address poor performance of file-based applications. Caches store frequently accessed data objects (files, web pages or attachments) locally at remote locations and replicate and synchronize that data with servers, but this approach has limitations. For instance, when an end-user changes and renames a data object, caches no longer recognize that this data object has moved across the network and cannot optimize its transfer. In addition, caching approaches have inflexible architectures with limited ability to extend to other applications and also increase the risk of data inconsistency; and |
| Ÿ | WAN optimization— WAN optimization products, which typically offer some combination of compression, TCP optimization and quality-of-service functions, can result in a reduction of network congestion and more efficient utilization of bandwidth. However, other WAN optimization products typically do not address application chattiness as comprehensively as we do and many do not provide for continued access to remote files during WAN failures. |
In addition to their limited application, these point products often involve deployment and operational complexities that cause network disruption, and inefficiency, and difficulties scaling to large numbers of locations. They may often require server or client re-configuration, or complex pre-installation configuration that demands significant amounts of time from IT personnel.

Table of Contents
Over time, point-product vendors have attempted to incorporate additional functionality to solve for their limitations. These amalgamations of legacy approaches with additional layers of features often suffer from the same underlying issues with their legacy underpinnings; insufficient performance improvement over a broad spectrum of data networking traffic, scaling difficulties, and deployment and operational complexity.
Need for a Comprehensive Solution
Alternative approaches have failed to comprehensively address all of the root causes of wide-area distributed computing problems for a broad range of applications, and offer only limited performance enhancement. Some vendors have attempted to combine capabilities of otherwise more limited approaches through partnerships and acquisitions, but the resulting products have been poorly integrated and have failed to improve the performance of a sufficiently wide array of applications. We believe significant demand exists for an integrated, flexible and comprehensive WDS solution that adequately addresses the root causes of the fundamental performance problems of wide-area distributed computing.
The Riverbed Solution
We have developed an innovative and comprehensive solution that broadly addresses the inter-related root causes of poor performance of wide-area distributed computing: latency and protocol chattiness, and bandwidth limitations. By simultaneously addressing these causes, we are able to improve significantly the performance of applications and access to data across WANs and enable the consolidation of costly IT infrastructure. Our WDS solution consists of the Riverbed Optimization System (RiOS™), our proprietary software that is embedded on a general purpose hardware computing platform to form our Steelhead appliances. We also embed RiOS in our Steelhead Mobile software designed for use on mobile worker laptop computers.
Through the application of our proprietary technology, our WDS solution simultaneously addresses each of these root causes of poor WAN performance:
| Ÿ | Application protocol chattiness — Our Application Streamlining technology significantly reduces unnecessary protocol chattiness for a broad range of applications; |
| Ÿ | Network protocol chattiness — Our Transport Streamlining technology employs a variety of techniques to significantly improve TCP performance. Our technology allows more data to be transmitted in each trip, which reduces the number of trips required; and |
| Ÿ | Bandwidth limitations — Our Data Streamlining technology employs sophisticated data mapping and pattern recognition techniques to minimize the amount of redundant data traversing WAN connections. Our products detect requests for redundant information and send very little more than the data that has actually been modified over the WAN. |
When combined, these key technologies allow us to deliver significant benefits to our customers, including the ability to:
| Ÿ | Accelerate performance of applications and access to data over the WAN— Our solution enables our customers to recognize dramatic increases in performance of applications and access to data across a WAN, typically increasing transmission speeds by 5 to 50 times and in some cases by up to 100 times. Benefits include increased employee productivity, more efficient collaboration of globally distributed workgroups and more consistent rollout and adoption of enterprise applications; |
| Ÿ | Consolidate geographically distributed IT resources— Our solution enables the consolidation of remote office infrastructure, including servers, storage back-up systems, databases and IT |

Table of Contents
support personnel, while achieving more LAN-like performance. Also, consolidation enhances data security by centralizing IT resources in more secure datacenters; |
| Ÿ | Reduce the need for WAN bandwidth — Our solution nearly eliminates redundant traffic traversing the WAN and enables more efficient use of existing bandwidth, reducing the pressure to add bandwidth, which is often expensive or unavailable, as network traffic increases; |
| Ÿ | Shorten storage back-up and replication time over the WAN— Our solution enables back-up and replication of data over the WAN in a fraction of the time previously allocated to the task. Additional benefits to our solution include reduced IT support needed to execute daily back-up procedures, as well as reduced security concerns related to storing and transporting backed-up data on physical tape media at every remote computing location; and |
| Ÿ | Improve productivity and reduce frustration for IT managers and end-users — Our solution allows users in sites linked by a WAN to collaborate and share files and other data without the delays normally caused by WANs. Additional benefits include faster development cycles, better data synchronization, lower error rates and more flexibility with respect to staffing and personnel coordination. |
Our products are designed to be easily and transparently deployed into our customers’ networks. Our products are also designed to be easily managed, scalable across networks of all sizes and to address the wide-area distributed computing needs of every major industry.
The Riverbed Strategy
Our goal is to establish our solution as the preeminent performance and efficiency standard for organizations relying on wide-area distributed computing. Key elements of our strategy include:
| Ÿ | Maintain and extend our technological advantages— We believe that we offer the broadest ability to enable rapid, reliable access to applications and data for our customers. We intend to enhance our position as a leader and innovator in the WDS market. We also intend to continue to sell new capabilities into our installed base; |
| Ÿ | Enhance and extend our product line — We plan to introduce new models of our current products as well as enhancements to their capabilities in order to address our customers’ size and application requirements. We also plan to introduce new products to extend our market and utilize our technology platform to extend our capabilities; |
| Ÿ | Increase market awareness— To generate increased demand for our products, we will continue promoting our brand and the effectiveness of our comprehensive WDS solution; |
| Ÿ | Scale our distribution channels — We intend to leverage and expand our indirect channels to extend our geographic reach and market penetration; and |
| Ÿ | Enhance and extend our support and services capabilities — We plan to enhance and extend our support and services capabilities to continue to support our growing global customer base. |

configuring, monitoring, reporting and upgrading large numbers of Steelhead appliances. The U.S. list prices of our CMC appliances currently range from $4,995 to $49,995.
Our InterceptorTM is a complementary product designed to enable flexible and scalable deployment of a cluster of Steelhead appliances in complex, high traffic data center environments without requiring complex network reconfiguration, making the deployment of a Riverbed-based solution simpler, faster and more scalable than alternatives. The U.S. list price of our Interceptor appliance is currently $34,995.
In addition to accelerating the performance of applications across the WAN, Steelhead and CMC products utilize our Management Streamlining technology to simplify deployment, configuration, management, and ongoing maintenance, thereby lowering the total cost of ownership of our products. Management Streamlining offers the following benefits:
| Ÿ | Ease of deployment — Our products are designed to be more easily and seamlessly integrated into networks than alternative approaches with full support for most existing routing and networking configurations. Steelhead products can automatically detect each other within an organization’s WAN and be automatically configured across WAN links to begin optimizing data without the need to manually set up complicated appliance-to-appliance network tunnels; and |
| Ÿ | Simplified management— Our products simplify remote-site appliance management by enabling remote configuration, management and updating of Steelhead products. In addition, our products also provide performance reporting capabilities necessary to deliver relevant performance information to centralized IT resources. |
In August 2007, we launched Steelhead Mobile, a software product that incorporates RiOS to accelerate the performance of applications and access to data from mobile worker laptops. The U.S. list price of a Steelhead Mobile software license is approximately $350 per concurrently connected end-user. A customer must have at least one Steelhead Appliance in their network to which Steelhead Mobile will connect. A Steelhead Mobile Controller appliance is used to manage Steelhead Mobile connections. The U.S. list price for a Steelhead Mobile Controller bundled with 30 Steelhead Mobile licenses is currently $12,995.
Technology
The Riverbed Optimization System (RiOS) is our proprietary software platform that provides the core intelligence for our Steelhead products. To achieve performance improvements across a broad range of applications, RiOS integrates four key sets of technologies: Data Streamlining, Transport Streamlining, Application Streamlining and Management Streamlining.
Data Streamlining
Our Data Streamlining technologies address bandwidth limitations in existing networks. Our patented approach can be applied to all data and applications that run over TCP to reduce bandwidth consumption by dramatically reducing the need to send the same data multiple times over the WAN. Data Streamlining also supports the classification of individual data packets for quality-of-service and route control.
In a non-optimized WAN setting, each time data is requested by a remote user, all of the data must be sent across the WAN, regardless of whether identical data (or an insignificantly modified version of the data) has previously been sent. In wide-area distributed computing environments where Steelhead products have been deployed, all of the requested data must be sent across the WAN only the first time data is requested by a user, at which time that data is stored by the Steelhead products on both sides of the network. In subsequent requests, redundant data segments will not be sent
9
Table of Contents
regardless of what application is requesting the data or which user is making the request. The detection of repetitive data patterns is very granular, with a typical segment of data being as small as approximately 100 bytes. This fine level of granularity enables Steelhead products to detect tiny changes in files, e-mails, web pages and other application data, sending only those changes across the WAN.
Each end-user request for data is sent directly to the intended authoritative application server as opposed to a cache that typically utilizes a copy of the data. Our Steelhead product intercepts the server response, identifies redundant data patterns and then sends only the new segments across the WAN to the end-user. All of the existing segments are represented by references which point to those already existing segments stored on the end-user side of the WAN connection. In this way, significantly less traffic needs to be sent to deliver large amounts of data to the end-user. In addition, this approach eliminates data consistency issues inherent in cache-based approaches.
Transport Streamlining
Transport Streamlining enhances the performance of the TCP protocol by increasing the amount of data carried per TCP round trip, thereby reducing the number of round trips required to move a given amount of data over the WAN. We accomplish this by both increasing the default TCP payload and by filling the window with references to data rather than actual data.
We also enhance TCP performance by reducing the time associated with creating new TCP connections (especially for small, short-lived transfers), adapting transfer parameters based on real-time network characteristics and assigning priority for necessary packet resends due to packet loss. A component of Transport Streamlining, High Speed TCP, also addresses the TCP chattiness and latency that is particularly pronounced in high speed connections (for example OC-12 (622 Mbps)). Another component of transport streamlining, MXTCP, is designed to address private networks with packet loss.
Application Streamlining
Application Streamlining provides a further mechanism to enhance the performance of specific applications. Many applications were designed for use over a LAN and require hundreds to thousands of interactions between client and server to execute even simple requests, such as opening a file. By understanding the semantics of particular application protocols, Steelhead products reduce chattiness, collapsing hundreds of client-server interactions into a few round trips over the WAN.
While most important business applications that run over TCP immediately benefit from Data Streamlining and Transport Streamlining, Application Streamlining enables us to add additional acceleration for specific applications. We have built specific Application Streamlining modules that support file, e-mail, web, ERP, and database application protocols (CIFS, MAPI, HTTP, Oracle 11i, SSL, NFS and MS-SQL). We have also built special modules to address protocol inefficiencies for common storage back-up and replication applications. We believe these applications are especially inefficient in wide-area distributed computing. We have designed our architecture to enable additional Application Streamlining modules to be incorporated easily over time.
Management Streamlining
Management Streamlining allows for simplified implementation and administration of our Steelhead products. Unlike alternative approaches which usually require changes to clients, servers, routers and switches or the addition of an overlay network of tunnels, Steelhead products are designed to be transparently installed in existing IT infrastructure with minimal administration. The auto-discovery
10
Table of Contents
capabilities of RiOS allow our Steelhead products to identify automatically all Steelhead products on the WAN, typically without a need to reconfigure any network infrastructure. Our products automatically intercept WAN traffic without any further configuration requirements to applications, clients, or other network infrastructure, while allowing non-optimized traffic to simply pass through.
Our RiOS software provides IT administrators with simplified management of Steelhead products through Command Line Interface (CLI), Graphical User Interface (GUI) and an optional Central Management Console.
Other key elements of Management Streamlining include touchless configuration options, over-the-wire software upgrades for Steelhead products, singular and grouped appliance management and customizable reporting analytics.
Customers
Our products have been sold to over 3,500 customers worldwide in every major industry, including manufacturing, finance, technology, government, architecture, engineering and construction, professional services, utilities, healthcare and pharmaceuticals, media and retail. Our products are deployed in a wide range of organizations, from large global organizations with hundreds or thousands of locations to smaller organizations with few locations. During the years ended December 31, 2005, 2006 and 2007, no single customer accounted for 10% or more of our consolidated revenue.
Sales and Marketing
We sell our products and support through indirect distribution partners and our field sales force:
| Ÿ | Indirect distribution partners — We have over 500 channel partners worldwide, primarily VARs and System Integrators. These partners help market and sell our products to a broad array of organizations and allow us to leverage our field sales force; and |
| Ÿ | Field sales force — We have a field sales force that is responsible for managing all direct and indirect sales within each of our geographic territories. |
Our marketing activities include lead generation, advertising, website operations, direct marketing, public relations, technology conferences and trade shows.
Support and Services
We offer tiered customer support programs depending upon the service needs of our customers’ deployments. Support contracts provide customers rights to unspecified software product upgrades and maintenance releases issued when and if available during the support period. Product support includes internet access to technical content, as well as telephone access to technical support personnel. Support contracts typically have a one year term. We have support centers in New York, San Francisco Bay Area, Amsterdam area, London area, Singapore and Tokyo, which enable us to respond at all times. As we expand internationally, we plan to continue to hire additional technical support personnel to service our growing international customer base.
Primary product support for customers of our indirect distribution partners is often provided by the partners themselves and we provide back-up support.
Our product sales include a warranty on hardware and software. Hardware is typically warranted against material defects for 12 months. Software is typically warranted to meet published specifications for a period of 90 days.

Research and Development
Continued investment in research and development is critical to our business. To this end, we have assembled a team of engineers with expertise in various fields, including networking, applications, storage and systems management. We have invested significant time and financial resources into the development of our products. We plan to expand our product offerings and solutions capabilities in the future and plan to dedicate significant resources to these continued research and development efforts. Further, as we expand internationally and into different sectors, we may incur additional costs to conform our products to comply with local laws or local product specifications.
Research and development expenses were $39.7 million, $19.2 million, and $8.1 million in 2007, 2006, and 2005, respectively.
Manufacturing
We outsource manufacturing of all hardware products. Our manufacturers provide us with limited warranties to cover general component failures, and our larger manufacturing partners provide specific quality control processes and replacement cycle time commitments. In addition, the lead times associated with certain components are lengthy and make rapid changes in quantity requirements and delivery schedules difficult. Although we outsource manufacturing operations for cost-effective scale and flexibility, we perform rigorous quality control testing intended to ensure the reliability of Steelhead appliances once deployed. We provide long term forecasts to our manufacturing partners and we maintain oversight of their supply chain activities.
Shortages in components that we use in our products are possible and our ability to predict the availability of such components may be limited. Some of these components are available only from single or limited sources of supply. Our ability to timely deliver products to our customers would be materially adversely impacted if we needed to qualify replacements for any of a number of the components used in our products.
We outsource our logistics functions to third parties. These third parties ship our products on our behalf and perform certain other shipping and physical distribution capabilities.
Competition
The WDS market is highly competitive and continually evolving. We believe we compete primarily on the basis of offering a comprehensive WDS solution that broadly addresses the root causes of poor performance of wide-area distributed computing. We believe other principal competitive factors in our market include product performance, ability to deploy easily into existing networks and ability to remotely manage products. We believe that our solution performs better than competitive products as measured by a broad range of metrics encompassing application performance, compression ratios and data transfer times. Our ability to sustain such a competitive advantage depends on our ability to achieve continuous technological innovation and adapt to the evolving needs of our customers.
We believe we are currently the only provider of a comprehensive WDS solution. However, a large number of vendors have made acquisitions to enter the WDS market and continue to invest in this area.
Our primary competitors include Cisco Systems (through its Actona acquisition), Juniper Networks (through its Peribit Networks acquisition), Packeteer (through its Tacit Networks acquisition), BlueCoat Systems, F5 Networks (through its Swan Labs acquisition) and Citrix Systems (through its Orbital Data acquisition). We also face competition from a large number of smaller private companies and new market entrants.
12
Table of Contents
We believe that we compete favorably in each of the sub-segments of WAN optimization and WAFS in addition to being the only provider of a comprehensive WDS solution. As we have a purpose-built architecture, compared to many vendors attempts to combine separate technology elements, we believe we have a significant advantage in performance, ease-of-use, and ability to scale to large numbers of locations and employees.
Intellectual Property
Our success as a company depends upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks, as well as customary contractual protections.
We have been granted three United States patents for our Content-Based Segmentation Scheme (which covers aspects of our Data Streamlining), one United States patent for aspects of our Transaction Accelerator system (the architectural framework of RiOS), and one United States patent for our Cooperative Proxy Auto-Discovery and Connection Interception methods and apparatus. The granted United States patents will expire in 2022 or 2023. United States patent filings are intended to provide the holder with a right to exclude others from making, using, selling or importing in the U.S. the inventions covered by the claims of granted patents. We have United States provisional and non-provisional patent applications pending, as well as counterparts pending in other jurisdictions around the world. We do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims. Our granted United States patents, and to the extent any future patents are issued, any such future patents may be contested, circumvented or invalidated over the course of our business, and we may not be able to prevent third parties from infringing these patents. Therefore, the exact effect of having a patent cannot be predicted with certainty.
Our three registered trademarks in the United States are Riverbed, Steelhead and Riverbed (stylized). Our three registered trademarks in Japan are Riverbed, Steelhead and Riverbed (stylized). Our two registered trademarks in the European Community are Steelhead and Riverbed (stylized). We also have United States trademark applications pending to register Riverbed (stylized), RiOS, Interceptor, THINK FAST and the Riverbed Design mark, and a European Community trademark application pending for the mark Riverbed.
In addition to the foregoing protections, we generally control access to and use of our proprietary software and other confidential information through the use of internal and external controls, including contractual protections with employees, contractors, customers and partners, and our software is protected by United States and international copyright laws.
We also incorporate third-party software programs into our products pursuant to license agreements. These software programs enable us, for example, to configure a storage adapter for specific redundant disk setups, initialize and diagnose hardware on certain models, and help manage statistics and reporting. Any disruption in our access to these software programs could result in significant delays in our product releases and could require substantial effort to locate or develop a replacement program.
Employees
As of December 31, 2007, we had 623 employees in offices in all major geographies. Of these, 285 were engaged in sales and marketing, 181 in research and development, 69 in support and services, 83 in finance and administration and 5 in manufacturing. None of our U.S. employees are

represented by labor unions; however, in certain international subsidiaries workers councils represent our employees. We consider current employee relations to be good.
Available Information
Our Internet address is www.riverbed.com. There we make available, free of charge, our annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and any amendments to those reports, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. Our SEC reports can be accessed through the investor relations section of our website. The information found on our website is not part of this or any other report we file with or furnish to the SEC.
| Item 1A. | Risk Factors |
Set forth below and elsewhere in this Annual Report on Form 10-K, and in other documents we file with the SEC, are risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements contained in this Annual Report on Form 10-K. Because of the following factors, as well as other variables affecting our operating results, past financial performance should not be considered as a reliable indicator of future performance and investors should not use historical trends to anticipate results or trends in future periods.
Risks Related to Our Business and Industry
We compete in new and rapidly evolving markets and have a limited operating history, which make it difficult to predict our future operating results.
We were incorporated in May 2002 and shipped our first Steelhead appliance in May 2004. We have a limited operating history and offer a single line of products in an industry characterized by rapid technological change. It is very difficult to forecast our future operating results. You should consider and evaluate our prospects in light of the risks and uncertainty frequently encountered by early stage companies in rapidly evolving markets characterized by rapid technological change, changing customer needs, evolving industry standards and frequent introductions of new products and services. As we encounter rapidly changing customer requirements and increasing competitive pressures, we likely will be required to reposition our product and service offerings and introduce new products and services. We may not be successful in doing so in a timely and appropriately responsive manner, or at all. Furthermore, because we compete in an early stage market, many of our target customers have not purchased products similar to ours and might not have a specific budget for the purchase of our products and services. All of these factors make it difficult to predict our future operating results.
Our operating results may fluctuate significantly, which makes our future results difficult to predict and could cause our operating results to fall below expectations or our guidance.
Our quarterly and annual operating results have varied significantly in the past and will vary significantly in the future, which makes it difficult for us to predict our future operating results. Our operating results may fluctuate due to a variety of factors, many of which are outside of our control, including the changing U.S. and global economic environment, and any of which may cause our stock price to fluctuate. As a result, comparing our operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of our future performance. In addition, revenues in any quarter are largely dependent on customer contracts entered into during that quarter. Moreover, a significant portion of our quarterly sales typically occurs during the last month of the quarter, which we believe reflects customer buying patterns of products similar to ours and other products in the technology industry generally. As a result, our quarterly operating results are difficult to predict even in the near term and a delay in an anticipated sale past the end of a particular quarter may
14
Table of Contents
negatively impact our results of operations for that quarter, or in some cases, that year. A delay in the recognition of revenue, even from just one account, may have a significant negative impact on our results of operations for a given period. If our revenue or operating results fall below the expectations of investors or securities analysts or below any guidance we may provide to the market, the price of our common stock would likely decline substantially. Such a decline could occur, and has occurred in the past, even when we have met our publicly stated revenue and/or earnings guidance. We are rapidly expanding the number of personnel, programs and infrastructure to accommodate and facilitate anticipated future growth. If revenues are less than anticipated, then our financial results would be adversely affected.
In addition to other risk factors listed in this “Risk Factors” section, factors that may affect our operating results include, but are not limited to:
| Ÿ | fluctuations in demand, including due to seasonality, for our products and services. For example, many companies in our industry experience adverse seasonal fluctuations in customer spending patterns, particularly in the first and third quarters; we have experienced these seasonal fluctuations in the past and expect that this trend will continue in the future; |
| Ÿ | fluctuations in sales cycles and prices for our products and services; |
| Ÿ | reductions in customers’ budgets for information technology purchases and delays in their purchasing cycles; |
| Ÿ | general economic conditions in our domestic and international markets; |
| Ÿ | limited visibility into customer spending plans; |
| Ÿ | changing market conditions, including current and potential customer consolidation; |
| Ÿ | customer concentration; |
| Ÿ | the timing of recognizing revenue in any given quarter as a result of software revenue recognition rules, including the extent to which sales transactions in a given period are unrecognizable until a future period or, conversely, the satisfaction of revenue recognition rules in a given period resulting in the recognition of revenue from transactions initiated in prior periods; |
| Ÿ | the sale of our products in the timeframes we anticipate, including the number and size of orders, and the product mix within any such orders, in each quarter; |
| Ÿ | our ability to develop, introduce and ship in a timely manner new products and product enhancements that meet customer requirements; |
| Ÿ | the timing of product releases or upgrades by us or by our competitors; |
| Ÿ | any significant changes in the competitive dynamics of our markets, including new entrants or substantial discounting of products; |
| Ÿ | our ability to control costs, including our operating expenses and the costs of the components we purchase; |
| Ÿ | volatility in our stock price, which may lead to higher stock compensation expenses pursuant to Statement of Financial Accounting Standards No. 123(R); and |
| Ÿ | unpredictable fluctuations in our effective tax rate due to disqualifying dispositions of stock from the employee stock purchase plan and stock options, changes in the valuation of our deferred tax assets or liabilities, changes in actual results versus our estimates, or changes in tax laws, regulations, accounting principles, or interpretations thereof. |

We face intense competition that could reduce our revenue and adversely affect our financial results.
The market for our products is highly competitive and we expect competition to intensify in the future. Other companies may introduce new products in the same markets we serve or intend to enter.
This competition could result in increased pricing pressure, reduced profit margins, increased sales and marketing expenses and failure to increase, or the loss of, market share, any of which would likely seriously harm our business, operating results or financial condition.
Competitive products may in the future have better performance, more and/or better features, lower prices and broader acceptance than our products. Many of our current or potential competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater financial, technical, sales, marketing and other resources than we do. Potential customers may prefer to purchase from their existing suppliers rather than a new supplier regardless of product performance or features. Currently, we face competition from a number of established companies, including Cisco Systems (which acquired Actona Technologies), Juniper Networks (which acquired Peribit Networks), Packeteer (which acquired Tacit Networks), Blue Coat Systems , F5 Networks (which acquired Swan Labs), and Citrix Systems (which acquired Orbital Data). We also face competition from a large number of smaller private companies and new market entrants.
We expect increased competition from other established and emerging companies if our market continues to develop and expand. For example, third parties currently selling our products could market products and services that compete with our products and services. In addition, some of our competitors have made acquisitions or entered into partnerships or other strategic relationships with one another to offer a more comprehensive solution than they individually had offered. We expect this trend to continue as companies attempt to strengthen or maintain their market positions in an evolving industry and as companies enter into partnerships or are acquired. Many of the companies driving this consolidation trend have significantly greater financial, technical and other resources than we do and are better positioned to acquire and offer complementary products and technologies. The companies resulting from these possible consolidations may create more compelling product offerings and be able to offer greater pricing flexibility, making it more difficult for us to compete effectively, including on the basis of price, sales and marketing programs, technology or product functionality. Continued industry consolidation may adversely impact customers’ perceptions of the viability of smaller and even medium-sized technology companies and consequently customers’ willingness to purchase from such companies. These pressures could materially adversely affect our business, operating results and financial condition.
We also face competitive pressures from other sources. For example, Microsoft has announced its intention to improve the performance of its software for remote office users. Our products are designed to improve the performance of many applications, including applications that are based on Microsoft protocols. Accordingly, improvements to Microsoft application protocols may reduce the need for our products, adversely affecting our business, operating results and financial condition. Improvement in other application protocols or in the Transmission Control Protocol (TCP), the underlying transport protocol for most WAN traffic, could have a similar effect. In addition, we market our products, in significant part, on the anticipated cost savings to be realized by organizations if they are able to avoid the purchase of costly IT infrastructure at remote sites by purchasing our products. To the extent other companies are able to reduce the costs associated with purchasing and maintaining servers, storage or applications to be operated at remote sites, our business, operating results and financial condition could be adversely affected.

We rely heavily on indirect distribution partners to sell our products. Disruptions to, or our failure to effectively develop and manage, our distribution channels and the processes and procedures that support them could harm our business.
Our future success is highly dependent upon establishing and maintaining successful relationships with a variety of indirect distribution partners, including value-added resellers. A substantial majority of our revenue is derived through indirect channel sales and we expect indirect channel sales to continue to account for a substantial majority of our total revenue. Accordingly, our revenue depends in large part on the effective performance of these channel partners, and the loss of or reduction in sales to our channel partners could materially reduce our revenues. By relying on indirect channels, we may have little or no contact with the ultimate users of our products, thereby making it more difficult for us to establish brand awareness, ensure proper delivery and installation of our products, service ongoing customer requirements and respond to evolving customer needs. In addition, we recognize a large portion of our revenue based on a sell-through model using information regarding the end user customers that is provided by our channel partners. If those channel partners provide us with inaccurate or untimely information, the amount or timing of our revenues could be adversely impacted.
Recruiting and retaining qualified channel partners and training them in our technology and product offerings requires significant time and resources. In order to develop and expand our distribution channel, we must continue to scale and improve our processes and procedures that support our distribution channel, including investment in systems and training, and those processes and procedures may become increasingly complex and difficult to manage. We have no long-term contracts or minimum purchase commitments with any of our value-added resellers or other indirect distributors, and our contracts with these channel partners do not prohibit them from offering products or services that compete with ours. Our competitors may be effective in providing incentives to existing and potential channel partners to favor their products, to choose not to partner with us, or to prevent or reduce sales of our products. Our channel partners may choose not to offer our products exclusively or at all. If we fail to maintain successful relationships with our channel partners, fail to develop new relationships with channel partners in new markets or expand the number of channel partners in existing markets, fail to manage, train or motivate existing channel partners effectively or if these channel partners are not successful in their sales efforts, sales of our products may decrease and our business, operating results and financial condition would be materially adversely affected.
Adverse economic conditions or reduced information technology spending may harm our business.
Our business depends on the overall demand for information technology, and in particular for Wide-area Data Services, and on the economic health and general willingness to make capital commitments of our current and prospective customers. The market we serve is emerging and the purchase of our products involves material changes to established purchasing patterns and policies. In addition, the purchase of our products is often discretionary and may involve a significant commitment of capital and other resources. In addition, our operating expenses are largely based on anticipated revenue trends and a high percentage of our expenses are, and will continue to be, fixed in the short-term. Uncertainty about future economic conditions makes it difficult to forecast operating results and to make decisions about future investments. Weak economic conditions, or a reduction in information technology spending even if economic conditions improve, would likely harm our business and operating results in a number of ways, including longer sales cycles, lower prices for our products and services and reduced unit sales.

We expect our gross margins to vary over time and our recent level of product gross margin may not be sustainable.
Our product gross margins vary from quarter to quarter and the recent level of gross margins may not be sustainable and may be adversely affected in the future by numerous factors, including product or sales channel mix shifts, increased price competition, increases in material or labor costs, excess product component or obsolescence charges from our contract manufacturers, increased costs due to changes in component pricing or charges incurred due to component holding periods if our forecasts do not accurately anticipate product demand, warranty related issues, or our introduction of new products or entry into new markets with different pricing and cost structures.
We rely on third parties to perform shipping and other logistics functions on our behalf. A failure or disruption at a logistics partner would harm our business.
Currently, we use third party logistics partners to perform storage, packaging, shipment and handling for us. We intend to utilize additional logistics service providers in connection with any expansion of our international sales. Although the logistics services required by us may be readily available from a number of providers, it is time consuming and costly to qualify and implement these relationships. If one or more of our logistics partners suffers an interruption in its business, or experiences delays, disruptions or quality control problems in its operations, or we choose to change or add additional logistics partners, our ability to ship products to our customers would be delayed and our business, operating results and financial condition would be adversely affected.
We are susceptible to shortages or price fluctuations in our supply chain. Any shortages or price fluctuations in components used in our products could delay shipment of our products.
Shortages in components that we use in our products are possible and our ability to predict the availability of such components may be limited. Some of these components are available only from limited sources of supply. For example, our Steelhead appliances depend on network bypass cards to provide a fail-to-wire capability. These bypass cards use high speed relays available only from a limited number of vendors. In addition, our ability to timely deliver products to our customers would be harmed if we needed to qualify replacements for the systems, motherboards, chassis and storage adapters used in our appliances. We would be similarly impacted by shortages in the availability, or the complete unavailability, of the central processing units, bypass cards, disks, memory, fans and power supplies that we use in our appliances. Specifically, the unavailability of any of these components would prevent us from shipping products because each of these components is necessary to the proper functioning of our appliances. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantity requirements and delivery schedules.
Any growth in our business or the economy is likely to create greater pressures on us and our suppliers to project overall component demand accurately and to establish optimal component inventory levels. In addition, increased demand by third parties for the components we use in our products may lead to decreased availability and higher prices for those components. We carry very little inventory of our product components, and we rely on our suppliers to deliver necessary components to our contract manufacturers in a timely manner based on forecasts we provide. We rely on both purchase orders and long-term contracts with our suppliers. As a result, even if available, we may not be able to secure sufficient components at reasonable prices or of acceptable quality to build products in a timely manner, which would seriously impact our ability to deliver products to our customers, and impact our revenue.

If we fail to predict accurately our manufacturing requirements, we could incur additional costs or experience manufacturing delays which would harm our business. We are dependent on contract manufacturers, and changes to those relationships, expected or unexpected, may result in delays or disruptions that could harm our business.
We depend on independent contract manufacturers to manufacture and assemble our products. We rely on purchase orders or long-term contracts with our contract manufacturers. Some of our contract manufacturers are not obligated to supply products to us for any specific period, in any specific quantity or at any specific price. Our orders may represent a relatively small percentage of the overall orders received by our contract manufacturers from their customers. As a result, fulfilling our orders may not be considered a priority by one or more of our contract manufacturers in the event the contract manufacturer is constrained in its ability to fulfill all of its customer obligations in a timely manner. We provide demand forecasts to our contract manufacturers. If we overestimate our requirements, the contract manufacturers may assess charges or we may have liabilities for excess inventory, each of which could negatively affect our gross margins. Conversely, because lead times for required materials and components vary significantly and depend on factors such as the specific supplier, contract terms and the demand for each component at a given time, if we underestimate our requirements, the contract manufacturers may have inadequate materials and components required to produce our products, which could interrupt manufacturing of our products and result in delays in shipments and deferral or loss of revenue.
Although the contract manufacturing services required to manufacture and assemble our products may be readily available from a number of established manufacturers, it is time consuming and costly to qualify and implement contract manufacturer relationships. Therefore, if one or more of our contract manufacturers suffers an interruption in its business, or experiences delays, disruptions or quality control problems in its manufacturing operations, or we choose to change or add additional contract manufacturers, our ability to ship products to our customers would be delayed.
If functionality similar to that offered by our products is incorporated into existing network infrastructure products, organizations may decide against adding our products to their network, which would harm our business.
Other providers of network infrastructure products are offering or announcing functionality aimed at addressing the problems addressed by our products. For example, Cisco Systems incorporates WAN optimization functionality into certain of its router blades. The inclusion of, or the announcement of intent to include, functionality perceived to be similar to that offered by our products in products that are already generally accepted as necessary components of network architecture or in products that are sold by more established vendors may have an adverse effect on our ability to market and sell our products. Furthermore, even if the functionality offered by other network infrastructure providers is more limited than our products, a significant number of customers may elect to accept such limited functionality in lieu of adding additional appliances from an additional vendor. Many organizations have invested substantial personnel and financial resources to design and operate their networks and have established deep relationships with other providers of network infrastructure products, which may make them reluctant to add new components to their networks, particularly from new vendors. In addition, an organization’s existing vendors or new vendors with a broad product offering may be able to offer concessions that we are not able to match because we currently offer only a single line of products and have fewer resources than many of our competitors. If organizations are reluctant to add additional network infrastructure from new vendors or otherwise decide to work with their existing vendors, our business, operating results and financial condition will be adversely affected.

If we are unable to protect our intellectual property rights, our competitive position could be harmed or we could be required to incur significant expenses to enforce our rights.
We depend on our ability to protect our proprietary technology. We rely on trade secret, patent, copyright and trademark laws and confidentiality agreements with employees and third parties, all of which offer only limited protection. Despite our efforts, the steps we have taken to protect our proprietary rights may not be adequate to preclude misappropriation of our proprietary information or infringement of our intellectual property rights, and our ability to police such misappropriation or infringement is uncertain, particularly in countries outside of the United States. Further, with respect to patent rights, we do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims, and even if patents are issued, they may be contested, circumvented or invalidated over the course of our business. Moreover, the rights granted under any issued patents may not provide us with proprietary protection or competitive advantages, and competitors may be able to develop similar or superior technologies to our own now or in the future. Protecting against the unauthorized use of our products, trademarks and other proprietary rights is expensive, difficult and, in some cases, impossible. Litigation has been necessary and may be necessary in the future to enforce or defend our intellectual property rights, to protect our trade secrets or to determine the validity and scope of the proprietary rights of others. For example, on November 13, 2007, we served Quantum Corporation with a lawsuit, filed in the United States District Court, Northern District of California, alleging patent infringement. Also, on January 9, 2008, we filed an action in the United States District Court, Delaware, against Quantum Corporation and certain of its subsidiaries seeking a declaratory judgment of non-infringement and invalidity with respect to a certain patent owned by Quantum Corporation and/or certain of its subsidiaries. Such litigation could result in substantial costs and diversion of management resources, either of which could harm our business, operating results and financial condition. Furthermore, many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce their intellectual property rights than we do. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property.
Claims by others that we infringe their proprietary technology could harm our business.
Our industry is characterized by the existence of a large number of patents and frequent claims and related litigation regarding patent and other intellectual property rights. In the ordinary course of our business, we are involved in disputes and licensing discussions with others regarding their claimed proprietary rights and cannot assure you that we will always successfully defend ourselves against such claims. Third parties have claimed and may in the future claim that our products or technology infringe their proprietary rights. For example, on October 9, 2007, Quantum Corporation served us with a lawsuit, filed in the United States District Court, Northern District of California, alleging patent infringement. Also, on or about February 13, 2008, Quantum Corporation filed a lawsuit against us in the United States District Court, Northern District of California, alleging patent infringement of an additional patent. We expect that infringement claims may increase as the number of products and competitors in our market increases and overlaps occur. In addition, as we have gained greater visibility and market exposure as a public company, we face a higher risk of being the subject of intellectual property infringement claims. Any claim of infringement by a third party, even those without merit, could cause us to incur substantial costs defending against the claim, and could distract our management from our business. Furthermore, we could be subject to a judgment or voluntarily enter into a settlement, either of which could require us to pay substantial damages. A judgment or settlement could also include an injunction or other court order that could prevent us from offering our products. In addition, we might elect or be required to seek a license for the use of third party intellectual property, which may not be available on commercially reasonable terms or at all, or if available, the payments under such license may harm our operating results and financial condition. Alternatively, we may be required to develop non-infringing technology, which could require significant
20
Table of Contents
effort and expense and may ultimately not be successful. Any of these events pursuant to existing or future infringement claims could seriously harm our business, operating results and financial condition. Third parties may also assert infringement claims against our customers and channel partners. Any of these claims would require us to initiate or defend potentially protracted and costly litigation on their behalf, regardless of the merits of these claims, because we generally indemnify our customers and channel partners from claims of infringement of proprietary rights of third parties. If any of these claims succeed, or if we voluntarily enter into a settlement, we may be forced to pay damages on behalf of our customers or channel partners, which could have a material adverse effect on our business, operating results and financial condition.
Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, our revenue is difficult to predict and may vary substantially from quarter to quarter.
The timing of our revenue is difficult to predict. Our sales efforts involve educating our customers about the use and benefit of our products, including their technical capabilities and potential cost savings to an organization. Customers typically undertake a significant evaluation process that has in the past resulted in a lengthy sales cycle, in some cases over twelve months. Also, as our distribution strategy has evolved into a channel model, utilizing value-added resellers, distributors, systems integrators and service providers, the level of variability in the length of sales cycle across transactions may increase and make it more difficult to predict the timing of many of our sales transactions. We spend substantial time, effort and money in our sales efforts without any assurance that our efforts will produce any sales. In addition, product purchases are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing and other delays. If sales expected from a specific customer for a particular quarter are not realized in that quarter or at all, revenue may be harmed and we may miss our stated guidance for that period.
If we lose key personnel or are unable to attract and retain personnel on a cost-effective basis, our business would be harmed.
Our success is substantially dependent upon the performance of our senior management and key technical and sales personnel. Our management and employees can terminate their employment at any time, and the loss of the services of one or more of our executive officers or other key employees could harm our business. Our success also is substantially dependent upon our ability to attract additional personnel for all areas of our organization, particularly in our sales, research and development and customer service departments. Competition for qualified personnel is intense, and we may not be successful in attracting and retaining such personnel on a timely basis, on competitive terms, or at all. If we are unable to attract and retain the necessary technical, sales and other personnel on a cost-effective basis, especially in light of our recent and anticipated growth, our business, operating results and financial condition would be adversely affected.
We may not generate positive returns on our research and development investments.
Developing our products is expensive, and the investment in product development may involve a long payback cycle or may not generate additional revenue at all. In the year ended December 31, 2007, our research and development expenses were $39.7 million, or approximately 17% of our total revenue. Our future plans include significant investments in research and development and related product opportunities. We believe that we must continue to dedicate a significant amount of resources to our research and development efforts to maintain our competitive position. These investments may take several years to generate positive returns, if ever.

Our ability to sell our products is highly dependent on the quality of our support and services offerings, and our failure to offer high quality support and services would harm our operating results and reputation.
Once our products are deployed within our customers’ networks, our customers depend on our support organization to resolve any issues relating to our products. A high level of support is critical for the successful marketing and sale of our products. If we or our channel partners do not effectively assist our customers in deploying our products, succeed in helping our customers quickly resolve post-deployment issues, and provide effective ongoing support, it would adversely affect our ability to sell our products to existing customers and could harm our reputation with potential customers. In addition, as we expand our operations internationally, our support organization will face additional challenges including those associated with delivering support, training and documentation in languages other than English. As a result, our failure to maintain high quality support and services would harm our operating results and reputation.
If we fail to manage future growth effectively, our business would be harmed.
We have expanded our operations significantly since inception and anticipate that further significant expansion will be required. This future growth, if it occurs, will place significant demands on our management, infrastructure and other resources. To manage any future growth, we will need to hire, integrate and retain highly skilled and motivated employees. We will also need to continue to improve our financial and management controls, reporting systems and procedures. We have converted to a new enterprise resource planning software system that has replaced a substantial majority of our prior finance, sales and inventory management systems. We may encounter delays or difficulties as a result of this conversion, including loss of data and decreases in productivity as our personnel become familiar with new systems. If we experience any delays or difficulties, either in connection with this new enterprise resource planning system or other controls, systems and procedures, our ability to properly run our business could be adversely impacted. For example, deficiencies in our internal controls over financial reporting could result in loss of revenue, improper revenue recognition, or errors in our financial statements. If we do not effectively manage our growth, our business would be harmed.
If we do not successfully anticipate market needs and develop products and product enhancements that meet those needs, or if those products do not gain market acceptance, our business and operating results will be harmed.
We may not be able to anticipate future market needs or be able to develop new products or product enhancements to meet such needs, either on a timely basis or at all. For example, our failure to address additional application-specific protocols, particularly if our competitors are able to provide such functionality, could harm our business. In addition, our inability to diversify beyond our current product offerings could adversely affect our business. Any new products or product enhancements that we introduce, including our recently introduced Steelhead Mobile product, may not achieve any significant degree of market acceptance or be accepted into our sales channel by our channel partners, which would adversely affect our business and operating results.
Organizations are increasingly concerned with the security of their data, and to the extent they elect to encrypt data being transmitted from the point of the end-user in a format that we’re not able to decrypt, rather than only across the WAN, our products will become less effective.
Our products are designed to remove the redundancy associated with repeated data requests over a WAN, either through a private network or a virtual private network (VPN). The ability of our products to reduce such redundancy depends on our products’ ability to recognize the data being requested. Our products currently detect and decrypt some forms of encrypted data. Since most
22
Table of Contents
organizations currently encrypt most of their data transmissions only between sites and not on the LAN, the data is not encrypted when it passes through our products. For those organizations that elect to encrypt their data transmissions from the end-user to the server in a format that we’re not able to decrypt, our products will offer little performance improvement unless we are successful in incorporating additional functionality into our products that address those encrypted transmissions. Our failure to provide such additional functionality could limit the growth of our business and harm our operating results.
If our products do not interoperate with our customers’ networks, installations will be delayed or cancelled, which would harm our business.
Our products must interoperate with our customers’ existing networks, which often have different specifications, utilize multiple protocol standards and products from multiple vendors, and contain multiple generations of products that have been added over time. If we find errors in the existing software or defects in the hardware used in our customers’ networks or problematic network configurations or settings, as we have in the past, we may have to modify our software or hardware so that our products will interoperate with our customers’ networks. This could cause longer installation times for our products and could cause order cancellations, either of which would adversely affect our business, operating results and financial condition. In addition, government and other customers may require our products to comply with certain security or other certifications and standards. If our products are late in achieving or fail to achieve compliance with these certifications and standards, or our competitors achieve compliance with these certifications and standards, we may be disqualified from selling our products to such customers, or at a competitive disadvantage, which would harm our business, operating results and financial condition
Our products are highly technical and may contain undetected software or hardware errors, which could cause harm to our reputation and our business.
Our products, including software product upgrades and releases, are highly technical and complex and, when deployed, are critical to the operation of many networks. Our products have contained and may contain undetected errors, defects or security vulnerabilities. Some errors in our products may only be discovered after a product has been installed and used by customers. Some of these errors may be attributable to third party technologies incorporated into our products, which makes us dependant upon the cooperation and expertise of such third parties for the diagnosis and correction of such errors. Any errors, defects or security vulnerabilities discovered in our products after commercial release could result in loss of revenue or delay in revenue recognition, loss of customers and increased service and warranty cost, any of which could harm our reputation, business, operating results and financial condition. Any such errors, defects or security vulnerabilities could also adversely affect the market’s perception of our products and business. In addition, we could face claims for product liability, tort or breach of warranty, including claims relating to changes to our products made by our channel partners. Our contracts with customers contain provisions relating to warranty disclaimers and liability limitations, which may not be upheld. Defending a lawsuit, regardless of its merit, is costly and may divert management’s attention and harm the market’s perception of us and our products. In addition, if our business liability insurance coverage proves inadequate or future coverage is unavailable on acceptable terms or at all, our business, operating results and financial condition could be adversely impacted.
We may engage in future acquisitions that could disrupt our business and cause dilution to our stockholders.
In the future we may acquire other businesses, products or technologies. We have not made any acquisitions to date. Our ability as an organization to make acquisitions is unproven. We may not be able to find suitable acquisition candidates and we may not be able to complete acquisitions on

Table of Contents
favorable terms, if at all. If we do complete acquisitions, we may not ultimately strengthen our competitive position or achieve our goals, or the acquisition may be viewed negatively by customers, financial markets or investors. In addition, with respect to any acquisitions that we make, we may encounter difficulties in integrating personnel and operations from the acquired businesses and in retaining and motivating key personnel from these businesses. Acquisitions may disrupt our ongoing operations, divert management from day-to-day responsibilities and increase our expenses. Future acquisitions may reduce our cash available for operations and other uses and could result in an increase in amortization expense related to identifiable assets acquired, potentially dilutive issuances of equity securities or the incurrence of debt.
Our international sales and operations subject us to additional risks that may harm our operating results.
In 2005, we derived approximately 18% of our revenue from customers outside the United States. This number increased to approximately 37% in the year ended December 31, 2007. We have personnel in numerous countries worldwide. We expect to continue to add personnel in additional countries. Our international operations subject us to a variety of risks, including:
| Ÿ | the difficulty of managing and staffing international offices and the increased travel, infrastructure and legal compliance costs associated with multiple international locations; |
| Ÿ | difficulties in enforcing contracts and collecting accounts receivable, and longer payment cycles, especially in emerging markets; |
| Ÿ | tariffs and trade barriers and other regulatory or contractual limitations on our ability to sell or develop our products in certain foreign markets; |
| Ÿ | increased exposure to foreign currency exchange rate risk; and |
| Ÿ | reduced protection for intellectual property rights in some countries. |
International customers may also require that we localize our products. The product development costs for localizing the user interface of our products, both graphical and textual, could be a material expense to us if the software requires extensive modifications. To date, such changes have not been extensive and the costs have not been material.
As we continue to expand our business globally, our success will depend, in large part, on our ability to anticipate and effectively manage these and other risks associated with our international operations. Our failure to manage any of these risks successfully could harm our international operations, reduce our international sales and harm our business, operating results and financial condition.
Our use of open source and third-party software could impose limitations on our ability to commercialize our products.
We incorporate open source software into our products. Although we monitor our use of open source closely, the terms of many open source licenses have not been interpreted by United States courts, and there is a risk that such licenses could be construed in a manner that could impose unanticipated conditions or restrictions on our ability to commercialize our products. In such event, we could be required to seek licenses from third parties in order to continue offering our products, to re-engineer our products or to discontinue the sale of our products in the event re-engineering cannot be accomplished on a timely basis, any of which could adversely affect our business, operating results and financial condition.
24
Table of Contents
We also incorporate certain third-party technologies, including software programs, into our products and may need to utilize additional third-party technologies in the future. However, licenses to relevant third-party technology may not continue to be available to us on commercially reasonable terms, or at all. Therefore, we could face delays in product releases until equivalent technology can be identified, licensed or developed, and integrated into our current products. These delays, if they occur, could materially adversely affect our business, operating results and financial condition. We currently use third-party software programs in our Steelhead appliances, our Interceptor appliances, our Central Management Console appliances and our recently available Steelhead Mobile software client and controller. For example, in our Steelhead appliances, we use third-party software to configure a storage adapter for specific redundant disk setups as well as to initialize and diagnose hardware on certain models, and in our Central Management Console and Steelhead Mobile Controller appliances we use third-party software to help manage statistics and reporting. Each of these software programs is currently available from only one vendor. As a result, any disruption in our access to these software programs could result in significant delays in our product releases and could require substantial effort to locate or develop a replacement program. If we decide in the future to incorporate into our products any other software program licensed from a third party, and the use of such software program is necessary for the proper operation of our appliances, then our loss of any such license would similarly adversely affect our ability to release our products in a timely fashion.
We are subject to various regulations that could subject us to liability or impair our ability to sell our products.
Our products are subject to a variety of government regulations, including export controls, import controls, environmental laws and required certifications. In particular, our products are subject to U.S. export controls and may be exported outside the U.S. only with the required level of export license or through an export license exception, because we incorporate encryption technology into our products. In addition, various countries regulate the import of certain encryption technology and have enacted laws that could limit our ability to distribute our products or could limit our customers’ ability to implement our products in those countries. Changes in our products or changes in regulations may create delays in the introduction of our products in international markets, prevent our customers with international operations from deploying our products throughout their global systems or, in some cases, prevent the export or import of our products to certain countries altogether. Any change in regulations, shift in approach to the enforcement or scope of existing regulations, or change in the countries, persons or technologies targeted by such regulations, could result in decreased use of our products by, or in our decreased ability to export or sell our products to, existing or potential customers with international operations. We must comply with various and increasing environmental regulations, both domestic and international, regarding the manufacturing and disposal of our products. For example, we must comply with Waste Electrical and Electronic Equipment Directive laws, which are being adopted by certain European Economic Area countries on a country-by-country basis. Failure to comply with these and similar laws on a timely basis, or at all, could have a material adverse effect on our business, operating results and financial condition. This would also be true if we fail to comply, either on a timely basis or at all, with any U.S. environmental laws regarding the manufacturing or disposal of our products. Any decreased use of our products or limitation on our ability to export or sell our products would harm our business, operating results and financial condition.
We incur significant costs as a result of operating as a public company, and our management devotes substantial time to new compliance initiatives.
We incur significant legal, accounting and other expenses as a public company, including costs resulting from regulations regarding corporate governance practices and costs relating to compliance with Section 404 of the Sarbanes-Oxley Act. For example, the listing requirements of the Nasdaq Stock Market’s Global Select Market require that we satisfy certain corporate governance requirements relating to independent directors, audit committees, distribution of annual and interim reports,
25
Table of Contents
stockholder meetings, stockholder approvals, solicitation of proxies, conflicts of interest, stockholder voting rights and codes of conduct. Our management and other personnel devote a substantial amount of time to these compliance initiatives. Moreover, these rules and regulations have increased our legal and financial compliance costs and will make some activities more time-consuming and costly. For example, these rules and regulations could make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.
While we believe that we currently have adequate internal control over financial reporting, we are exposed to risks from legislation requiring companies to evaluate those internal controls.
The Sarbanes-Oxley Act requires that we test our internal control over financial reporting and disclosure controls and procedures. In particular, for the year ended December 31, 2007, we have performed system and process evaluation and testing of our internal control over financial reporting to allow management and our independent registered public accounting firm to report on the effectiveness of our internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act. Our compliance with Section 404 will require that we incur substantial expense and expend significant management time on compliance-related issues. Moreover, if we are not able to comply with the requirements of Section 404 in the future, or if we or our independent registered public accounting firm identify deficiencies in our internal control over financial reporting that are deemed to be material weaknesses, the market price of our stock may decline and we could be subject to sanctions or investigations by the Nasdaq Stock Market’s Global Select Market, the SEC or other regulatory authorities, which would require significant additional financial and management resources.
We are required to expense equity compensation given to our employees, which has reduced our reported earnings, will harm our operating results in future periods and may reduce our stock price and our ability to effectively utilize equity compensation to attract and retain employees.
We historically have used stock options and an employee stock purchase plan as a significant component of our employee compensation program in order to align employees’ interests with the interests of our stockholders, encourage employee retention, and provide competitive compensation packages. The Financial Accounting Standards Board has adopted changes that require companies to record a charge to earnings for employee stock option grants and other equity incentives. We adopted this standard effective January 1, 2006. By causing us to record significantly increased compensation costs, such accounting changes have reduced, and will continue to reduce, our reported earnings, will harm our operating results in future periods, and may require us to reduce the availability and amount of equity incentives provided to employees, which could make it more difficult for us to attract, retain and motivate key personnel. Moreover, if securities analysts, institutional investors and other investors adopt financial models that include stock option expense in their primary analysis of our financial results, our stock price could decline as a result of reliance on these models with higher expense calculations.
If we need additional capital in the future, it may not be available to us on favorable terms, or at all.
We have historically relied on outside financing and cash flow from operations to fund our operations, capital expenditures and expansion. We may require additional capital from equity or debt financing in the future to fund our operations or respond to competitive pressures or strategic opportunities. We may not be able to secure timely additional financing on favorable terms, or at all. The terms of any additional financing may place limits on our financial and operating flexibility. If we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new securities we issue could have rights, preferences and
26
Table of Contents
privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us, if and when we require it, our ability to grow or support our business and to respond to business challenges could be significantly limited.
Our business is subject to the risks of earthquakes, fire, floods and other natural catastrophic events, and to interruption by manmade problems such as computer viruses or terrorism.
Our corporate headquarters are located in the San Francisco Bay Area, a region known for seismic activity. A significant natural disaster, such as an earthquake, fire or a flood, could harm our business, operating results and financial condition. In addition, our servers are vulnerable to computer viruses, break-ins and similar disruptions from unauthorized tampering with our computer systems. In addition, acts of terrorism or war could cause disruptions in our or our customers’ business or the economy as a whole. To the extent that such disruptions result in delays or cancellations of customer orders or the deployment of our products, our business, operating results and financial condition would be adversely affected.
Risks Related to Ownership of Our Common Stock
The trading price of our common stock has been volatile and is likely to be volatile in the future.
The trading prices of the securities of technology companies have been highly volatile. Further, our common stock has a limited trading history. Since our initial public offering in September 2006 through February 14, 2008, our stock price has fluctuated from a low of $13.60 to a high of $52.81. Factors that could affect the trading price of our common stock include, but are not limited to:
| Ÿ | variations in our operating results; |
| Ÿ | announcements of technological innovations, new services or service enhancements, strategic alliances or significant agreements by us or by our competitors; |
| Ÿ | the gain or loss of significant customers; |
| Ÿ | recruitment or departure of key personnel; |
| Ÿ | changes in the estimates of our operating results, either by us or by any securities analysts who follow our common stock, or changes in recommendations by any securities analysts who follow our common stock; |
| Ÿ | significant sales, or announcement of significant sales, of our common stock by us or our stockholders, including our directors and executive officers; |
| Ÿ | announcements by or about us regarding events or news adverse to our business; |
| Ÿ | market conditions in our industry, the industries of our customers and the economy as a whole; and |
| Ÿ | adoption or modification of regulations, policies, procedures or programs applicable to our business. |
If the market for technology stocks or the stock market in general experiences loss of investor confidence, the trading price of our common stock could decline for reasons unrelated to our business, operating results or financial condition. The trading price of our common stock might also decline in reaction to events that affect other companies in our industry or the stock market generally even if these events do not directly affect us. Each of these factors, among others, could cause our stock price to decline. Some companies that have had volatile market prices for their securities have had securities class actions filed against them. If a suit were filed against us, regardless of its merits or outcome, it could result in substantial costs and divert management’s attention and resources.
27
Table of Contents
If securities or industry analysts do not publish research or publish inaccurate or unfavorable research about our business, our stock price and trading volume could decline.
The trading market for our common stock will continue to depend in part on the research and reports that securities or industry analysts publish about us or our business. If we do not continue to maintain adequate research coverage or if one or more of the analysts who covers us downgrades our stock or publishes inaccurate or unfavorable research about our business, our stock price would likely decline. If one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.
Insiders have substantial control over us and will be able to influence corporate matters.
As of December 31, 2007, our directors and executive officers and their affiliates beneficially owned, in the aggregate, approximately 22.1% of our outstanding common stock. As a result, these stockholders will be able to exercise significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions, such as a merger or other sale of our company or its assets. This concentration of ownership could limit your ability to influence corporate matters and may have the effect of delaying or preventing a third party from acquiring control over us.
Anti-takeover provisions in our charter documents and Delaware law could discourage, delay or prevent a change in control of our company and may affect the trading price of our common stock.
We are a Delaware corporation and the anti-takeover provisions of the Delaware General Corporation Law may discourage, delay or prevent a change in control by prohibiting us from engaging in a business combination with an interested stockholder for a period of three years after the person becomes an interested stockholder, even if a change in control would be beneficial to our existing stockholders. In addition, our restated certificate of incorporation and amended and restated bylaws contain provisions that may discourage, delay or prevent a change in our management or control over us that stockholders may consider favorable.
| Item 1B. | Unresolved Staff Comments |
None.
| Item 2. | Properties |
We lease approximately 85,000 square feet of office space in San Francisco, California in a lease that expires in 2014. In addition, we lease approximately 46,000 square feet of office space in Sunnyvale, California pursuant to a lease that expires in 2013. We maintain customer service centers in New York, San Francisco Bay Area, Amsterdam area, London area, Singapore and Tokyo, and sales offices in multiple locations worldwide. We believe that our current facilities are suitable and adequate to meet our current needs and we intend to add new facilities or expand existing facilities as necessary.
| Item 3. | Legal Proceedings |
From time to time, we are subject to various legal proceedings, claims and litigation arising in the ordinary course of business. Other than as discussed in Note 13 to the Consolidated Financial Statements, we do not believe we are party to any currently pending legal proceedings the outcome of which may have a material adverse effect on our financial position, results of operations or cash flows.

(b) Use of Proceeds from Public Offering of Common Stock
In September 2006, we completed our initial public offering (IPO) pursuant to a registration statement on Form S-1 (Registration No. 333-133437) which the SEC declared effective on September 20, 2006. Under the registration statement, we registered the offering and sale of an aggregate of 9,990,321 shares of our common stock, and another 100,000 shares of our common stock sold by a selling stockholder. The offering did not terminate until after the sale of all of the shares registered on the registration statement. All of the shares of common stock issued pursuant to the registration statement, including the shares sold by the selling stockholder, were sold at a price to the public of $9.75 per share. The managing underwriters were Goldman, Sachs & Co., Citigroup Global Markets Inc., Deutsche Bank Securities Inc., and Thomas Weisel Partners LLC.

Table of Contents
As a result of the IPO, we raised a total of $87.5 million in net proceeds after deducting underwriting discounts and commissions of $6.8 million and offering expenses of $3.1 million. On October 2, 2006 we used $1.5 million of our proceeds to pay off our credit facility.
In February 2007, we completed our follow-on public offering pursuant to a registration statement on Form S-1 (Registration No. 333-140544) which the U.S. Securities and Exchange Commission declared effective on February 22, 2007. Under this registration statement, we registered the offering and sale of 2,854,671 shares of our common stock (including 250,000 shares sold by us pursuant to the underwriters’ exercise of their over-allotment option) and another 2,645,329 shares of our common stock sold by certain selling stockholders. The offering did not terminate until after the sale of all of the shares registered on the registration statement. All of the shares of common stock issued pursuant to the registration statement, including the shares sold by the selling stockholders, were sold at a price to the public of $32.50 per share. The managing underwriters were Goldman, Sachs & Co., Deutsche Bank Securities Inc., Citigroup Global Markets Inc., and Thomas Weisel Partners LLC.
As a result of the follow-on public offering, we raised a total of $87.7 million in net proceeds after deducting underwriting discounts and commissions of $4.2 million and other offering costs of $0.9 million. No payments for such expenses were made directly or indirectly to (i) any of our officers or directors or their associates, (ii) any persons owning 10% or more of any class of our equity securities, or (iii) any of our affiliates. We did not receive any proceeds from the sale of shares in the follow-on public offering by the selling stockholders.
We have applied the remaining net proceeds from the IPO and the follow-on public offering to our working capital for general corporate purposes, which may include expansion of our domestic and international sales and marketing organizations, investments in our infrastructure to support our anticipated growth, further development and expansion of our service offerings and possible acquisitions of complementary businesses, technologies or other assets. We have no current agreements or commitments with respect to any material acquisitions. We invested the net proceeds in short-term, interest-bearing, investment grade securities. There has been no material change in the planned use of proceeds from the IPO and the follow-on public offering as described in the final prospectuses filed with respect to such public offerings with the Securities and Exchange Commission pursuant to Rule 424(b).

| Item 7. | Management’s Discussion and Analysis of Financial Condition and Results of Operations |
The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the consolidated financial statements and related notes included elsewhere in this Annual Report on Form 10-K. The information in this Annual Report on Form 10-K contains forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Such statements are based upon current expectations that involve risks and uncertainties. Any statements contained herein that are not statements of historical facts may be deemed to be forward-looking statements.

Overview
We were founded in May 2002 by experienced industry leaders with a vision to improve the performance of wide-area distributed computing. Having significant experience in caching technology, our executive management team understood that existing approaches failed to address adequately all of the root causes of this poor performance. We determined that these performance problems could be best solved by simultaneously addressing inefficiencies in software applications and wide area networks, or WANs, as well as insufficient or unavailable bandwidth. This innovative approach served as the foundation of the development of our products. We began commercial shipments of our products in May 2004 and have since sold our products to over 3,500 customers worldwide. We now offer 13 models of our Steelhead appliances as well as our Central Management Console, Interceptor and Steelhead Mobile product line.
In August 2007 we began selling our new Steelhead® Mobile product line, which includes a software client version of our Steelhead appliances, which delivers LAN-like application performance to any employee laptop, whether on the road, working from home or connected wirelessly in the office.
We are headquartered in San Francisco, California. Our personnel are located throughout the United States and in over twenty countries worldwide. We expect to continue to add personnel in the United States and internationally to provide additional geographic sales, research and development, general and administrative, and technical support coverage.
In September 2006, we completed our initial public offering, or IPO, of common stock in which we sold and issued 9,990,321 shares of our common stock, at an issue price of $9.75 per share. We raised a total of $97.4 million in gross proceeds from the IPO, or approximately $87.5 million in net proceeds after deducting underwriting discounts and commissions of $6.8 million and other offering costs of $3.1 million. Upon the closing of the IPO, all outstanding shares of our convertible preferred stock automatically converted into 39,441,439 shares of common stock.
In February 2007, we completed a follow-on public offering of common stock in which we sold and issued 2,854,671 shares of our common stock, including 250,000 shares sold by us pursuant to the underwriters’ partial exercise of their over-allotment option, at an issue price of $32.50 per share. As a result of the offering, we raised a total of $92.8 million in gross proceeds, or approximately $87.7 million in net proceeds after deducting underwriting discounts and commissions of $4.2 million and other offering costs of $0.9 million.

Outlook. We believe that our current value proposition, which enables customers to improve the performance of their applications and access to their data across WANs, while also offering the ability to simplify IT infrastructure and realize significant capital and operations cost savings, should allow us to continue to grow our business. Our product revenue growth rate will depend significantly on continued growth in the wide-area data services, or WDS, market and our ability to continue to attract new customers in that market and generate additional sales from existing customers. Our growth in support and services revenue is dependent upon increasing the number of products under support contracts, which is dependent on both growing our installed base of customers and renewing existing support contracts. Our future profitability and rate of growth will be directly affected by the continued acceptance of our products in the marketplace, as well as the timing and size of orders, product mix, average selling prices and costs of our products and general economic conditions. Our ability to maintain profitability will also be affected by the extent to which we must incur additional expenses to expand our sales, marketing, development, and general and administrative capabilities to grow our business. The largest component of our expenses is personnel costs. Personnel costs consist of salaries, benefits and incentive compensation for our employees, including commissions for sales personnel and stock-based compensation. We expect that each of these expenses will continue to grow in absolute dollars and generally decrease as a percentage of revenue over time.
Revenue. We derive our revenue from sales of our products and support and services. Our revenue has grown rapidly since we began shipping products in May 2004, increasing from $2.6 million for the year ended December 31, 2004 to $236.4 million for the year ended December 31, 2007. As of December 31, 2007, our products had been sold to over 3,500 customers.
We sell our products directly through our sales force and indirectly through resellers. We derived 89% of our revenue through indirect channels in the year ended December 31, 2007. We expect revenue from resellers to continue to constitute a substantial majority of our future revenue.
Cost of Revenue. Cost of product revenue consists of the costs of appliance hardware, manufacturing personnel, manufacturing, shipping and logistics costs, and expenses for inventory obsolescence and warranty obligations. We utilize third parties to jointly develop and manufacture our appliance hardware, embed our proprietary software and perform shipping logistics. Cost of support and service revenue is primarily comprised of the personnel costs of providing technical support and professional services. Cost of ratable product and related support and services consists of hardware, support and service costs related to transactions recognized ratably. As we expand internationally and into other sectors, we may incur additional costs to conform our products to comply with local laws or local product specifications. In addition, as we expand internationally, we will continue to hire additional technical support personnel to support our growing international customer base.
Gross Margin. Our gross margin has been and will continue to be affected by a variety of factors, including the mix and average selling prices of our products, new product introductions and enhancements, the cost of our appliance hardware, cost of support and services personnel, and the mix of distribution channels through which our products are sold.
Operating Expenses. Operating expenses consist of sales and marketing, research and development and general and administrative expenses. Personnel-related costs are the most significant component of each of these expense categories. We grew from 325 employees at December 31, 2006 to 623 employees at December 31, 2007. We expect to continue to hire large numbers of new employees to support our anticipated growth. The timing of these additional hires has and could materially affect our operating expenses, both in absolute dollars and as a percentage of revenue, in any particular period.
35
Table of Contents
Sales and marketing expenses represent the largest component of our operating expenses and include personnel costs, sales commissions, marketing programs and facilities costs. Marketing programs are intended to generate revenue from new and existing customers, and are expensed as incurred. We expect sales and marketing expenses to increase as we hire additional personnel and spend more on marketing programs with the intent to grow our revenue. The majority of our international personnel are engaged in sales, marketing and support activities. The percentage of sales and marketing expenses incurred internationally grew from 11% in 2004 to 30% in the year ended December 31, 2007.
Research and development expenses primarily include personnel costs and facilities costs. Quality assurance, infrastructure and related costs of product quality efforts are also included. We expense research and development expenses as incurred. We are devoting substantial resources to the continued development of additional functionality for existing products and the development of new products. We intend to continue to invest significantly in our research and development efforts because we believe they are essential to maintaining our competitive position. Investments in research and development personnel costs are expected to increase in total dollars.
General and administrative expenses consist primarily of personnel costs related to our executive, finance, human resource, information technology and legal organizations, and fees for professional services. Professional services include outside legal, audit and information technology consulting costs.
Stock-Based Compensation Expense. Effective January 1, 2006, we began to measure and recognize compensation expense for stock-based awards at fair value, in accordance with Statement of Financial Accounting Standard No. 123 (revised 2004),Share-Based Payment, or SFAS 123(R). Prior to the adoption of SFAS 123(R) we accounted for stock options under the intrinsic value method in accordance with Accounting Principles Board Opinion No. 25,Accounting for Stock Issued to Employees, or APB 25. In the fourth quarter of 2006, we implemented the 2006 Employee Stock Purchase Plan, or Purchase Plan. Under the Purchase Plan, employees may purchase shares of common stock at a price per share that is 85% of the lesser of the fair market value of our common stock as of the beginning or the end of a purchase period. The Purchase Plan is compensatory and results in compensation expense accounted for under SFAS 123(R). We expect to continue to incur significant stock-based compensation expense.
Other Income (expense), net. Other income (expense), net primarily includes interest income on cash and marketable securities. Cash has historically been invested in highly liquid investments such as time deposits held at major banks, commercial paper, United States government agency discount notes, money market mutual funds and other money market securities with maturities at the date of purchase of 90 days or less. . In 2006 and 2005, other income (expense), net included the impact of recording our outstanding preferred stock warrants at fair value. Subsequent to our IPO, we were no longer required to re-measure our warrants to fair value.
Critical Accounting Policies and Estimates
Our consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (GAAP). These accounting principles require us to make certain estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented. We believe that the estimates and judgments upon which we rely are reasonable based upon information available to us at the time that these estimates and judgments are made. To the extent there are material differences between these estimates and actual results, our consolidated financial statements could be adversely affected. The accounting policies that reflect our
36
Table of Contents
more significant estimates and judgments and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results include revenue recognition, stock-based compensation, income taxes, inventory valuation and allowances for doubtful accounts.
Revenue Recognition
Our software is integrated on appliance hardware and is essential to the functionality of the product. As a result, we account for revenue in accordance with Statement of Position, or SOP, 97-2,Software Revenue Recognition, as amended by SOP 98-9,Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions, for all transactions involving the sale of software. We recognize product revenue when all of the following have occurred: (1) we have entered into a legally binding arrangement with a customer; (2) delivery has occurred, which is when product title transfers to the customer; (3) customer payment is deemed fixed or determinable and free of contingencies and significant uncertainties; and (4) collection is probable.
Product revenue consists of revenue from sales of our appliances and software licenses. Product sales include a perpetual license to our software. Product revenue is generally recognized upon transfer of title at shipment, assuming all other revenue recognition criteria are met. Shipping charges billed to customers are included in product revenue and the related shipping costs are included in cost of product revenue. Product revenue on sales to resellers is recorded once we have received persuasive evidence of an end-user and all other revenue recognition criteria have been met.
Substantially all of our products have been sold in combination with product support services, which consist of software updates and support. Software updates provide customers with rights to unspecified software product upgrades and to maintenance releases and patches released during the term of the support period. Support includes internet access to technical content, telephone and internet access to technical support personnel and hardware support. Revenue for support services is recognized on a straight-line basis over the service contract term, which is typically one year.
We use the residual method to recognize revenue when a product agreement includes one or more elements to be delivered at a future date and vendor specific objective evidence, or VSOE, of the fair value of all undelivered elements exists. Through December 31, 2007, in virtually all of our contracts, the only element that remained undelivered at the time of delivery of the product was support and updates. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the contract fee is recognized as product revenue. If evidence of the fair value of one or more undelivered elements does not exist, all revenue is generally deferred and recognized when delivery of those elements occurs or when fair value can be established. When the undelivered element is support, revenue for the entire arrangement is bundled and recognized ratably over the support period. Revenue related to these arrangements is included in ratable product and related support and services revenue in the accompanying consolidated statements of operations. VSOE of fair value for elements of an arrangement is based upon the normal pricing and discounting practices for those services when sold separately, and for product support and updates, is additionally measured by the renewal rate offered to the customer. Prior to the third quarter of 2005, we had not established VSOE for the fair value of support contracts provided to our reseller class of customers. As such, prior to the third quarter of 2005, we recognized all revenue on transactions sold through resellers ratably over the term of the support contract, typically one year. Beginning in the third quarter of 2005, we determined that we had established VSOE of fair value of support for products sold to resellers, and began recognizing product revenue upon title transfer at shipment, provided the remaining criteria for revenue recognition had been met.
Our fees are typically considered to be fixed or determinable at the inception of an arrangement, generally based on specific products and quantities to be delivered. Substantially all of our contracts do
37
Table of Contents
not include rights of return or acceptance provisions. To the extent that our agreements contain such terms, we recognize revenue once the acceptance provisions or right of return lapses. Payment terms to customers generally range from net 30 to 60 days. In the event payment terms are provided that differ from our standard business practices, the fees are deemed to not be fixed or determinable and revenue is recognized when the payments become due, provided the remaining criteria for revenue recognition have been met.
We assess the ability to collect from our customers based on a number of factors, including credit worthiness of the customer and past transaction history of the customer. If the customer is not deemed credit worthy, we defer all revenue from the arrangement until payment is received and all other revenue recognition criteria have been met.
Stock-Based Compensation
Prior to January 1, 2006, we accounted for employee stock options using the intrinsic value method in accordance with Accounting Principles Board, or APB, Opinion No. 25,Accounting for Stock Issued to Employees, or APB 25, and Financial Accounting Standards Board Interpretation, or FIN 44,Accounting for Certain Transactions Involving Stock Compensation, an Interpretation of APB No. 25 and had adopted the disclosure only provisions of Statement of Financial Accounting Standards, or SFAS, No. 123,Accounting for Stock-Based Compensation (SFAS 123) and SFAS No. 148,Accounting for Stock-Based Compensation — Transition and Disclosure (SFAS 148) using the minimum value method.
In accordance with APB 25, stock-based compensation expense, which is a non-cash charge, resulted from stock option grants at exercise prices that, for financial reporting purposes, were deemed to be below the estimated fair value of the underlying common stock on the date of grant. Through December 31, 2005, we recorded deferred stock-based compensation relative to these options of approximately $9.9 million which is being amortized over the service period, which generally corresponds to the vesting period of the applicable options on a straight-line basis. During the years ended December 31, 2007, 2006 and 2005 respectively, we amortized $2.3 million, $2.4 million and $1.3 of deferred compensation expense, net of reversals for terminations, relative to these options.
Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS No. 123(R),Share-Based Payment, using the prospective transition method, which requires us to apply the provisions of SFAS 123(R) to new awards granted, and to awards modified, repurchased or cancelled, after the effective date. Under this transition method, stock-based compensation expense recognized beginning January 1, 2006 is based on a combination of the following: (a) the grant-date fair value of stock option and employee stock purchase plan awards granted or modified after January 1, 2006; and (b) the amortization of deferred stock-based compensation related to stock option awards granted prior to January 1, 2006, which was calculated using the intrinsic value method as previously permitted under APB 25.
Under SFAS 123(R), we estimated the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. This model utilizes the estimated fair value of common stock and requires that, at the date of grant, we use the expected term of the option, the expected volatility of the price of our common stock, risk free interest rates and expected dividend yield of our common stock. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Options typically either vest with respect to 25% of the shares one year after the options’ vesting commencement date and the remainder ratably on a monthly basis over the following three years, or ratably on a monthly basis over four years. On September 20, 2006, we implemented our Employee Stock Purchase Plan, or Purchase Plan. Purchase Plan shares typically vest over two years, and include two purchase dates per year. The 2006 Purchase Plan became effective on the effective date of the registration statement relating to
38
Table of Contents
our IPO. Under the Purchase Plan, employees may purchase shares of common stock through payroll deductions at a price per share that is 85% of the lesser of the fair market value of our common stock as of the beginning of an applicable offering period or the applicable purchase date, with purchases generally every six months.
The fair value of options granted and Purchase Plan shares were estimated at the date of grant using the following assumptions:
| Year ended December 31, | ||||
| 2007 | 2006 | |||
Employee and Director Stock Options | ||||
Expected life in years | 4.5-6.0 | 4.5-6.1 | ||
Risk-free interest rate | 3.4%-4.9% | 4.6%-5.1% | ||
Volatility | 51%-62% | 62%-81% | ||
Weighted average fair value of grants | $11.35-$24.40 | $3.67-$18.40 | ||
Purchase Plan | ||||
Expected life in years | 0.5-2.0 | 0.5-2.0 | ||
Risk-free interest rate | 4.0%-5.0% | 4.8%-5.1% | ||
Volatility | 38%-46% | 42%-47% | ||
Weighted average fair value of grants | $8.04-$12.87 | $15.02-$15.52 | ||
The expected term represents the period that stock-based awards are expected to be outstanding. For the year ended December 31, 2007, we have elected to use the simplified method of determining the expected term of stock options as permitted by SEC Staff Accounting Bulletin 107. The computation of expected volatility for the year ended December 31, 2007 is based on the historical volatility of comparable companies from a representative peer group selected based on industry, financial and market capitalization data. As required by SFAS 123(R), we estimated expected forfeitures and are recognizing compensation costs only for those equity awards expected to vest.
As of December 31, 2007, total compensation cost related to stock options granted under SFAS 123(R) to employees and directors but not yet recognized as of December 31, 2007 was approximately $92.7 million, net of estimated forfeitures of $14.0 million. This cost will be amortized on a straight-line basis over the vesting period, which is typically 4 years. Amortization in the years ended December 31, 2007 and 2006 was $18.9 million and $4.3 million, respectively.
As of December 31, 2007, there was $9.1 million left to be amortized under our Purchase Plan, which will be amortized over the remaining Purchase Plan offering period, which is between 8 and 22 months. Amortization in the years ended December 31, 2007 and 2006 was $10.6 million and $2.5 million, respectively.
In accordance with SFAS 123(R), we have presented the cash-related tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options as financing cash flows for the year ended December 31, 2007. Tax benefits presented as financing cash flows for the year ended December 31, 2007 were $850,000. Tax benefits related to stock option exercises for options granted before the adoption of SFAS 123(R) are presented as operating cash flows.
Accounting for Income Taxes
We use the asset and liability method of accounting for income taxes in accordance with FASB Statement No. 109, Accounting for Income Taxes,Accounting for Income Taxes,(SFAS 109). Under this method, income tax expenses or benefits are recognized for the amount of taxes payable or refundable for the current year and for deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our consolidated financial statements or tax
39
Table of Contents
returns. The measurement of current and deferred tax assets and liabilities are based on provisions of currently enacted tax laws. The effects of future changes in tax laws or rates are not contemplated.
As part of the process of preparing consolidated financial statements, we are required to estimate our income taxes and tax contingencies in each of the tax jurisdictions in which we operate prior to the completion and filing of tax returns for such periods. This process involves estimating actual current tax expense together with assessing temporary differences in the treatment of items for tax purposes versus financial accounting purposes that may create net deferred tax assets and liabilities.
We record a valuation allowance to reduce our deferred tax assets to the amount we believe is more likely than not to be realized. In assessing the need for a valuation allowance, we have considered our historical levels of income, expectations of future taxable income and on going tax planning strategies. Because of the uncertainty of the realization of the deferred tax assets, we have recorded a full valuation allowance against our deferred tax assets. Realization of our deferred tax assets is dependent primarily upon future U.S. taxable income.
In June 2006, FASB issued interpretation No. 48,Accounting for Uncertainty in Income Taxes— an interpretation of FASB Statement No. 109, (FIN 48). This interpretation prescribes a recognition threshold and measurement attribute for tax positions taken or expected to be taken in a tax return. This interpretation also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The evaluation of a tax position in accordance with this interpretation is a two-step process. In the first step, recognition, we determine whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step addresses measurement of a tax position that meets the more-likely-than-not criteria. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in an increase in a liability for income taxes payable or a reduction of an income tax refund receivable, or a reduction in a deferred tax asset or an increase in a deferred tax liability, or both. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be de-recognized in the first subsequent financial reporting period in which that threshold is no longer met. We adopted the provisions of FIN 48 on January 1, 2007 and accrued approximately $157,000 as of December 31, 2007 as a result. We have also recognized a decrease in our deferred tax asset of $85,000 as of December 31, 2007. We have elected to record interest and penalties recognized in accordance with FIN 48 in the financial statements as income taxes.
Inventory Valuation
Inventory consists of hardware and related component parts and is stated at the lower of cost (on a first-in, first-out basis) or market. A portion of our inventory relates to evaluation units located at customer locations as some of our customers test our equipment prior to purchasing. Inventory that is obsolete or in excess of our forecasted demand is written down to its estimated realizable value based on historical usage, expected demand, and evaluation unit conversion rate and age. Inherent in our estimates of market value in determining inventory valuation are estimates related to economic trends, future demand for our products and technological obsolescence of our products. Inventory write-downs are reflected as cost of product and amounted to approximately $1.1 million, $1.5 million and $772,000 for the years ended December 31, 2007, 2006 and 2005.

Table of Contents
Allowances for Doubtful Accounts
We make judgments as to our ability to collect outstanding receivables and provide allowances for the applicable portion of receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding invoices. For those invoices not specifically reviewed, provisions are provided at differing rates, based upon the age of the receivable. In determining these percentages, we analyze our historical collection experience and current economic trends. If the historical data we use to calculate the allowance for doubtful accounts does not reflect the future ability to collect outstanding receivables, additional provisions for doubtful accounts may be needed and the future results of operations could be materially affected. The allowance for doubtful accounts was $734,000 and $472,000 and at December 31, 2007 and 2006.
Results of Operations
Revenue
We derive our revenue from sales of our appliances with bundled software licenses and from product support and services. We began shipping our products in May 2004.
Product revenue primarily consists of revenue from sales of our Steelhead products and is typically recognized upon shipment.
Support and services revenue includes unspecified software license updates and product support. Support revenue is recognized ratably over the contractual period, which is typically one year. Service revenue includes professional services and training, which to date has not been significant, and is recognized as the services are performed.
Ratable product and related support and services revenue includes revenue from arrangements in which product and support are bundled and no VSOE of fair value for support pricing in the arrangements exists. The total revenue from these arrangements is recognized ratably over the support period, typically one year.

2007 Compared to 2006: Product revenue increased in 2007 due primarily to an increase in new customers and additional purchases by existing customers. As of December 31, 2007, our products had been sold to over 3,500 customers, compared to approximately 1,600 as of December 31, 2006. We believe the market for our products has grown due to increased market awareness of wide area data services and distributed organizations, which increases dependence on timely access to data and applications.
Substantially all of our customers purchase support when they purchase our products. The increase in support and services revenue on an absolute basis and as a percentage of total revenues is a result of increased product and first year support sales combined with the renewal of support contracts by existing customers. As our customer base grows, we expect the proportion of revenue generated from support and services to increase.
In the year ended December 31, 2007, we derived 89% of our revenue from indirect channels compared to 75% in the year ended December 31, 2006. This increase in indirect channel revenue is due to our increased focus on expanding our indirect channel sales. We expect indirect channel revenue to continue to be a significant portion of our revenue.
We generated 37% of our revenue in the year ended December 31, 2007 from international locations, compared to 27% in the year ended December 31, 2006. We continue to expand into international locations and introduce our products in new markets and expect international revenue to increase in absolute dollars and as a percentage of revenue over time.
2006 Compared to 2005: Product revenue increased in 2006 due primarily to an increase in new customers and additional purchases by existing customers. As of December 31, 2006, our products had been sold to over 1,600 customers, compared to approximately 500 as of December 31, 2005.
The increase in support and services revenue on an absolute basis and as a percentage of total revenue is a result of increased product and first year support sales combined with the renewal of support contracts by existing customers.
The increase in ratable product and related support and services revenue in the year ended December 31, 2006 was due to the amortization of revenue from one of our OEM arrangements. Prior to the second quarter of 2006, we had undelivered obligations to this OEM and all revenue relating to this arrangement was deferred. In the quarter ended June 30, 2006, we satisfied all future obligations to this OEM, except for support. As such, in the second quarter we began amortizing revenue relating to this arrangement over the remaining support period for each sale made under the arrangement. In the year ended December 31, 2006, we recognized $2.2 million of revenue associated with this arrangement.
In the year ended December 31, 2006, we derived 75% of our revenue from indirect channels compared to 59% in the year ended December 31, 2005 due to our increased focus on expanding our indirect sales channels.
We generated 27% of our revenue in the year ended December 31, 2006 from international locations, compared to 18% in the year ended December 31, 2005.

2007 Compared to 2006: The increase in cost of product revenue was due primarily to increased hardware costs associated with higher revenue. Cost of support and services revenue increased as we added more technical support headcount domestically and abroad to support our growing customer base. Technical support and services headcount was 69 employees as of December 31, 2007 compared to 33 employees as of December 31, 2006.
Gross margins increased to 72% in the year ended December 31, 2007 from 67% in the year ended December 31, 2006 primarily due to higher margins on product revenue as a result of lower unit product costs and decreases in inventory valuation and warranty provisions as a percentage of product revenue.
2006 Compared to 2005: The increase in cost of product revenue was due primarily to increased hardware costs associated with increased shipments of our products to customers. Cost of support and services revenue increased as we added more technical support headcount domestically and abroad to support our growing customer base. Technical support headcount was 33 employees as of December 31, 2006 compared to 15 employees as of December 31, 2005. Cost of ratable product and related support and services increased due to more ratable reseller arrangements being amortized in the first half of 2006 partially offset by a decrease in the third quarter of 2006 as reseller arrangements entered into in the third quarter of 2005 were no longer recognized ratably and the one year amortization period for these contracts was complete.
Gross margins increased to 67% in the year ended December 31, 2006 from 63% in the year ended December 31, 2005 primarily due to increased margins on support and services as a result of growing our support installed base and support renewals at a greater rate than support personnel costs.

2007 Compared to 2006: The increase in sales and marketing expenses was primarily due to an increase in the number of sales and marketing employees, as sales and marketing headcount grew to 285 employees as of December 31, 2007 from 151 employees as of December 31, 2006. The increase in employees resulted in higher salary expense, employee related benefits and fees for recruitment of new employees. Additionally, commission expense increased in the year ended December 31, 2007 as compared to the year ended December 31, 2006 due to the substantial increase in revenue. Salaries, bonuses and commissions accounted for $18.5 million, marketing related activities accounted for $5.3 million, facilities and information technology expenses attributable to sales and marketing accounted for $4.8 million, and travel and entertainment expenses accounted for $3.5 million of the $47.6 million increase in sales and marketing expenses. Stock-based compensation, which was $15.2 million in the year ended December 31, 2007 compared to $4.6 million in the year ended December 31, 2006, accounted for approximately $10.6 million of the increase in sales and marketing expenses.
We plan to continue to make significant investments in sales and marketing with the intent to add new customers and increase penetration within our existing customer base by increasing the number of sales personnel worldwide, expanding our domestic and international sales and marketing activities, increasing channel penetration, building brand awareness and sponsoring additional marketing events. We expect future sales and marketing expenses to continue to increase and continue to be our most significant operating expense. Generally sales personnel are not immediately productive and sales and marketing expenses do not immediately result in revenue. Hiring additional sales personnel reduces short-term operating margins until the sales personnel become productive and generate revenue. Accordingly, the timing of sales personnel hiring and the rate at which they become productive will affect our future performance.
2006 Compared to 2005: The increase in sales and marketing expenses was primarily due to an increase in the number of sales and marketing employees, as sales and marketing headcount grew to 151 employees as of December 31, 2006 from 77 employees as of December 31, 2005. The increase in employees resulted in higher salary expense, employee-related benefits and fees for recruitment of new employees. Additionally, commission expense increased in the year ended December 31, 2006 as compared to the year ended December 31, 2005 due to the substantial increase in revenue. Salaries and commissions accounted for $15.3 million, travel and entertainment expenses accounted for $2.2 million, and marketing related activities accounted for $1.8 million of the $28.4 million increase in sales and marketing expenses. Stock-based compensation, which was $4.6 million in the year ended December 31, 2006 compared to $482,000 in the year ended December 31, 2005, accounted for approximately $4.2 million of the increase in sales and marketing expenses. The percentage of sales and marketing expenses incurred internationally grew to 34% in the year ended December 31, 2006 from 27% in the year ended December 31, 2005.

2007 Compared to 2006: Research and development expenses increased in the year ended December 31, 2007 compared to the year ended December 31, 2006 due to an increase in personnel and facility-related costs as a result of research and development headcount increasing to 181 employees as of December 31, 2007 from 109 employees as of December 31, 2006. Salaries and bonuses accounted for $6.2 million, facilities and information technology expenses accounted for $4.7 million and professional services account for $1.0 million of the $20.5 million increase in research and development expenses. Stock-based compensation, which was $8.6 million in the year ended December 31, 2007 compared to $2.5 million in the year ended December 31, 2006, accounted for $6.1 million of the increase in research and development expenses. We plan to continue to invest in research and development as we develop new products and make further enhancements to existing models.
2006 Compared to 2005: Research and development expenses increased in the year ended December 31, 2006 compared to the year ended December 31, 2005 due to an increase in personnel and facility related costs as a result of research and development headcount increasing to 109 employees as of December 31, 2006 from 66 employees as of December 31, 2005. Salaries accounted for $5.1 million of the $11.1 million increase in research and development expenses. Stock-based compensation, which was $2.5 million in the year ended December 31, 2006 compared to $397,000 in the year ended December 31, 2005, accounted for $2.1 million of the increase in research and development expenses. In addition, depreciation and related expenses increased as a result of additional information technology assets purchased in the second half of 2005 and in 2006.
General and Administrative Expenses
General and administrative expenses consist primarily of compensation for personnel and facilities costs related to our executive, finance, human resources, information technology and legal organizations, and fees for professional services. Professional services include outside legal, audit and information technology consulting costs.

2007 Compared to 2006: The increase in general and administrative expenses for the year ended December 31, 2007 compared to the year ended December 31, 2006 is due to an increase in personnel costs, primarily as a result of headcount increasing to 83 employees as of December 31, 2007 from 32 employees as of December 31, 2006, and an increase in professional services fees. Salaries and bonuses accounted for $2.7 million and professional service fees accounted for approximately $6.1 million of the $15.5 million increase in general and administrative expenses. Professional service fees increased due to increased Sarbanes-Oxley compliance fees, contract labor, information technology consulting fees and audit and tax advisory fees. Stock-based compensation,

which was $5.4 million in the year ended December 31, 2007 compared to $1.5 million in the year ended December 31, 2006, accounted for approximately $3.9 million of the increase in general and administrative expenses.
2006 Compared to 2005: The increase in general and administrative expenses for the year ended December 31, 2006 compared to the year ended December 31, 2005 is due to an increase in personnel costs, primarily as a result of headcount increasing to 32 employees as of December 31, 2006 from 16 employees as of December 31, 2005, and an increase in professional services fees. Salaries accounted for $1.8 million and professional service fees accounted for $1.7 million of the $5.8 million increase in general and administrative expenses. The additional personnel and professional services fees were primarily to address the legal, finance, human resources, recruiting and information technology functions required of a public company. Stock-based compensation, which was $1.5 million in the year ended December 31, 2006 compared to $368,000 in the year ended December 31, 2005, accounted for approximately $1.2 million of the increase in general and administrative expenses.

2007 Compared to 2006: Other income (expense), net, increased in the year ended December 31, 2007 primarily due to interest income on higher cash and marketable securities balances. We did not have interest expense in 2007, as we paid off the balance of our credit facility on October 2, 2006. Other expense decreased due to recording our preferred stock warrants to fair value in 2006 and no such adjustment was required in 2007. In the year ended December 31, 2006 we recognized a $644,000 charge to record our preferred stock warrants at fair value. Subsequent to our IPO, we were no longer required to record the warrants to fair value. Other expense in the year ended December 31, 2007 consists primarily of foreign currency losses.
2006 Compared to 2005: Other income (expense), net increased in 2006 due primarily to interest income on higher cash balances. In February 2006, we received net proceeds of $19.9 million from the issuance of 3,738,318 shares of Series D convertible preferred stock. In September 2006, we received net IPO proceeds of $87.5 million. Interest expense decreased slightly as we paid off the balance of our credit facility on October 2, 2006. Other expense increased due to recording our preferred stock warrants to fair value. In 2006 and 2005 we recorded $644,000 and $230,000 of warrant expense respectively. Subsequent to our IPO, we were no longer required to record the warrants to fair value.
Provision for Income Taxes
Prior to the first quarter of 2007, we had incurred operating losses and, accordingly, had not recorded a provision for income taxes for any of the periods presented other than foreign provisions for income tax. For the year ended December 31, 2007, we generated operating profits. After applying our available net operating loss and tax credit carryforwards, our tax provision accrued for the year ended December 31, 2007 consists of federal, foreign and state provisions for income tax.
46
Table of Contents
Since inception, we recorded a valuation allowance against our net deferred tax assets due to operating losses incurred. Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets were fully offset by a valuation allowance. If not utilized, the federal and state net operating loss and tax credit carryforwards will expire between 2013 and 2026 while the foreign net operating losses do not expire. Utilization of the federal and state net operating losses and credit carryforwards is subject to annual limitation that are applicable when we experienced an “ownership change”, by a change in significant stockholder allocation or equity structure.
If our recent trend of profitability continues, we may determine that there is sufficient positive evidence to support a reversal of, or decrease in, the valuation allowance. If we were to reverse all or some part of our valuation allowance and recognize all or some part of our deferred tax assets, our financial statements in the period of reversal would likely reflect an increase in assets on our balance sheet and a corresponding tax benefit to our statement of operations in the amount of the reversal.
Our effective tax rate for 2007 has fluctuated on a quarterly basis. Our effective tax rate is and can be affected by such items as disqualifying dispositions of stock from the Purchase Plan and incentive stock options, by changes in the valuation of our deferred tax assets or liabilities, or by changes in tax laws, regulations, accounting principles, or interpretations thereof. In addition, we are subject to potential income tax audits on open tax years by any taxing jurisdiction for which we operate in. The taxing authorities of the most significant jurisdictions are the United States Internal Revenue Service, California Franchise Tax Board and HM Revenue and Customs in the United Kingdom. Since all filed federal and California franchise tax returns have shown operating losses, we do not anticipate any material adjustments to the provisions relating to these returns. The statute of limitations for federal, state, and UK tax purposes are generally three, four, and three years respectively; however, we continue to carryover tax attributes prior to these periods for federal and state purposes, which would still be open for examination by the respective tax authorities. All years since our inception are open to tax examinations.

Our operating results may fluctuate due to a variety of factors, many of which are outside of our control. As a result, comparing our operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of our future performance. In addition, a significant portion of our quarterly sales typically occurs during the last month of the quarter, which we believe reflects customer buying patterns of products similar to ours and other products in the technology industry generally. As a result, our quarterly operating results are difficult to predict even in the near term.
Commencing with the first shipment of our products in the second quarter of 2004, revenue has increased sequentially each quarter, due to increases in the number of products sold to new and existing customers and international expansion. Cost of revenue has increased sequentially each quarter in absolute dollars; however, has decreased over time as a percentage of revenue. The increase in gross margins is primarily due to higher margins on product revenue as a result of lower unit product costs. Operating expenses in all quarters increased sequentially as we continued to add headcount and related costs to accommodate our growing business.

Cash and Cash Equivalents
Cash and cash equivalents consist of highly liquid investments in time deposits held at major banks, commercial paper, United States government agency discount notes, money market mutual funds and other money market securities with original maturities at the date of purchase of 90 days or less.
Marketable securities consist of government sponsored enterprise obligations and corporate bonds and notes. As of December 31, 2007 and 2006, the marketable securities are recorded at amortized cost, which approximates fair market value.
Pursuant to certain lease agreements and as security for our merchant services agreement with our financial institution, we are required to maintain cash reserves, classified as restricted cash. Current restricted cash totaled $142,000 at December 31, 2007 and $121,000 at December 31, 2006, and long-term restricted cash totaled $3.5 million and $1.5 million at December 31, 2007 and 2006, respectively. Long-term restricted cash is included in other assets in the consolidated balance sheets and consists primarily of funds held as collateral for letters of credit for the security deposit on the leases of our corporate headquarters and is restricted until the end of the lease terms on August 30, 2010 and July 31, 2014.
Since the fourth quarter of 2004, we have expanded our operations internationally. Our sales contracts are principally denominated in United States dollars and as such, the increase in our revenue derived from international customers, has not affected our cash flows from operations. As we fund our international operations, our cash and cash equivalents are affected by changes in exchange rates. To date, the foreign currency effect on our cash and cash equivalents has not been material.
Cash Flows from Operating Activities
Our largest source of operating cash flows is cash collections from our customers. Our primary uses of cash from operating activities are for personnel related expenditures, product costs, outside services and rent payments. Our cash flows from operating activities will continue to be affected principally by the extent to which we grow our revenue and spend on hiring personnel in order to grow our business. The timing of hiring sales personnel in particular affects cash flows as there is a lag between the hiring of sales personnel and the generation of revenue and cash flows from sales personnel.
Cash provided by operating activities was $48.2 million in the year ended December 31, 2007 compared to $297,000 in the year ended December 31, 2006 primarily due to increased profitability. In the first nine months of 2006, we experienced negative cash flows from operations as we continued to expand our business and build our infrastructure domestically and internationally.

Cash Flows from Investing Activities
Cash flows used in investing activities primarily relate to investments in marketable securities and capital expenditures to support our growth.
Cash used in investing activities increased in the year ended December 31, 2007 compared to the year ended December 31, 2006 due to additional purchases of marketable securities. Additionally, capital expenditures increased in 2007 compared to 2006 primarily resulting from leasehold improvement additions associated with our new corporate headquarters and software purchased for internal use associated with our ERP system. Restricted cash outlays increased in 2007 due to the cash collateralized $1.6 million letter of credit required for our new corporate headquarters.
Cash Flows from Financing Activities
Prior to September 2006, we financed our operations primarily through private sales of convertible preferred stock totaling $56.3 million and collections from customers and, to a lesser extent, borrowings under our credit facility. In February 2006, we sold 3,738,318 shares of our Series D convertible preferred stock for net proceeds of $19.9 million. In September 2006, we completed our IPO and received net proceeds of $87.5 million. In February 2007, we completed a follow-on public offering of our common stock and received net proceeds of $87.7 million.
On June 7, 2004, we entered into a loan and security agreement with a financial institution for a $2.5 million credit facility, and we borrowed $1.4 million and $1.1 million in 2004 and 2005, respectively. We made principal payments of $625,000 in the first six months of 2006 and repaid the remaining balance on our loan on October 2, 2006.
In addition to proceeds from our follow-on offering of common stock, cash flows from financing activities in the year ended December 31, 2007 consisted of cash proceeds and tax benefits received from the exercise of stock options and stock purchases under our Purchase Plan.
We believe that our net proceeds from operations, together with our cash and marketable securities balances at December 31, 2007, will be sufficient to fund our projected operating requirements for at least the next 12 months. Our future capital requirements will depend on many factors, including our rate of revenue growth, the expansion of our sales and marketing activities, the timing and extent of expansion into new territories, the timing of introductions of new products and enhancements to existing products, and the continuing market acceptance of our products. We may enter into arrangements for potential investments in, or acquisitions of, complementary businesses, services or technologies, which also could require us to seek additional equity or debt financing. Additional funds may not be available on terms favorable to us or at all.

| Item 7A. | Quantitative and Qualitative Disclosures about Market Risk |
Foreign Currency Risk
Our sales contracts are principally denominated in United States dollars and therefore our revenue is not subject to foreign currency risk. We do incur certain operating expenses in currencies other than the U.S. dollar and therefore are subject to volatility in cash flows due to fluctuations in foreign currency exchange rates, particularly changes in the British pound, Euro, Australian dollar and Singapore dollar. To date, we have not entered into any hedging contracts since exchange rate fluctuations have had minimal impact on our operating results and cash flows.
Interest Rate Sensitivity
We had unrestricted cash and cash equivalents totaling $163.0 million and $105.3 million at December 31, 2007 and 2006, respectively. The unrestricted cash and cash equivalents are held for working capital purposes. We do not enter into investments for trading or speculative purposes. Cash and cash equivalents include highly liquid investments with a maturity of ninety days or less at the time of purchase. Cash equivalents consist primarily of money market securities, U.S. treasury bills, U.S. agency discount notes and commercial paper. Due to the high investment quality and short duration of these investments, we do not believe that we have any material exposure to changes in the fair market value as a result of changes in interest rates. Declines in interest rates, however, will reduce future investment income. If overall interest rates had fallen by 10% in 2007, our interest income on cash and cash equivalents would have declined approximately $772,000, assuming consistent investment levels.

PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders
Riverbed Technology, Inc.
We have audited the accompanying consolidated balance sheets of Riverbed Technology, Inc. as of December 31, 2007 and 2006, and the related consolidated statements of operations, preferred stock and stockholders’ equity (deficit) and cash flows for each of the three years in the period ended December 31, 2007. Our audits also included the financial statement schedule listed in the index at Item 15(b). These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements 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 Riverbed Technology, Inc. at December 31, 2007 and 2006, and the consolidated results of its operations and its cash flows for each of the three years in the period ended December 31, 2007, 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.
As discussed in Note 1 to the consolidated financial statements, under the headings Stock-Based Compensation and Accounting for Income Taxes, the Company adopted Statement of Financial Accounting Standards No. 123(R), “Share-Based Payment”, effective January 1, 2006 and Financial Accounting Standards Board (FASB) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109”,effective January 1, 2007. As discussed in Note 2 to the consolidated financial statements, the Company adopted FASB Staff Position 150-5 (FSP 150-5) “Issuer’s Accounting under FASB Statement No. 150 for Freestanding Warrants and Other Similar Instruments on Shares that are Redeemable,”during the year ended December 31, 2005.
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Riverbed Technology, Inc.’s internal control over financial reporting as of December 31, 2007, 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 14, 2008 expressed an unqualified opinion thereon.

REPORT OF ERNST & YOUNG LLP, INDEPENDENT REGISTERED
PUBLIC ACCOUNTING FIRM
The Board of Directors and Stockholders
Riverbed Technology, Inc.
We have audited Riverbed Technology Inc.’s internal control over financial reporting as of December 31, 2007 based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Riverbed Technology, 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 which is contained in Part I, Item 9A of this Annual Report on From 10-K under the heading “Management’s 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, Riverbed Technology, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007 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 as of December 31, 2007 and 2006, and the related consolidated statements of operations, preferred stock and stockholders’ equity (deficit) and cash flows for each of the three years in the period ended December 31, 2007 and our report dated February 14, 2008 expressed an unqualified opinion thereon.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES
Organization
Riverbed Technology, Inc. was founded on May 23, 2002 and has developed a comprehensive solution to the fundamental problems of wide-area distributed computing. Our products enable our customers simply and efficiently to improve the performance of their applications and access to their data over wide area networks (WANs).
Public Offerings
In September 2006, we completed our initial public offering, or IPO, of common stock in which we sold and issued 9,990,321 shares of our common stock, including 1,290,321 shares sold by us pursuant to the underwriters’ exercise of their over-allotment option, at an issue price of $9.75 per share. We raised a total of $97.4 million in gross proceeds from the IPO, or approximately $87.5 million in net proceeds after deducting underwriting discounts and commissions of $6.8 million and other offering costs of $3.1 million. Upon the closing of the IPO, all shares of convertible preferred stock outstanding automatically converted into 39,441,439 shares of common stock.
In February 2007, we completed a follow-on public offering of common stock in which we sold and issued 2,854,671 shares of our common stock, including 250,000 shares sold by us pursuant to the underwriters’ partial exercise of their over-allotment option, at an issue price of $32.50 per share. As a result of the offering, we raised a total of $92.8 million in gross proceeds, or approximately $87.7 million in net proceeds after deducting underwriting discounts and commissions of $4.2 million and other offering costs of $0.9 million.
Significant Accounting Policies
Basis of Financial Statements
The consolidated financial statements include our accounts and the accounts of our wholly owned subsidiaries. Intercompany transactions and balances have been eliminated.
Use of Estimates
Our consolidated financial statements are prepared in accordance with Generally Accepted Accounting Principles, or GAAP. These accounting principles require us to make certain estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the consolidated financial statements, as well as the reported amounts of revenue and expenses during the periods presented. Significant estimates and assumptions made by management include the determination of the fair value of stock awards issued, inventory valuation and the allowance for doubtful accounts. We believe that the estimates and judgments upon which we rely are reasonable based upon information available to us at the time that these estimates and judgments are made. To the extent there are material differences between these estimates and actual results, our consolidated financial statements will be affected.
Revenue Recognition
Our software is integrated on appliance hardware and is essential to the functionality of the product. As a result, we account for revenue in accordance with Statement of Position, or SOP, 97-2,Software Revenue Recognition, as amended by SOP 98-9,Modification of SOP 97-2, Software Revenue Recognition, With Respect to Certain Transactions, for all transactions involving the sale of

software. We recognize product revenue when all of the following have occurred: (1) we have entered into a legally binding arrangement with a customer; (2) delivery has occurred, which is when product title transfers to the customer; (3) customer payment is deemed fixed or determinable and free of contingencies and significant uncertainties; and (4) collection is probable.
Product revenue consists of revenue from sales of our appliances and software licenses. Product sales include a perpetual license to our software. Product revenue is generally recognized upon transfer of title at shipment, assuming all other revenue recognition criteria are met. Shipping charges billed to customers are included in product revenue and the related shipping costs are included in cost of product revenue. Product revenue on sales to resellers is recorded once we have received persuasive evidence of an end-user and all other revenue recognition criteria have been met.
Substantially all of our products have been sold in combination with support services, which consist of software updates and support. Software updates provide customers with rights to unspecified software product upgrades and to maintenance releases and patches released during the term of the support period. Support includes internet access to technical content, telephone and internet access to technical support personnel and hardware support. Revenue for support services is recognized on a straight-line basis over the service contract term, which is typically one year.
We use the residual method to recognize revenue when a product agreement includes one or more elements to be delivered at a future date and vendor specific objective evidence, or VSOE, of the fair value of all undelivered elements exists. Through December 31, 2007, in virtually all of our contracts, the only element that remained undelivered at the time of delivery of the product was support and updates. Under the residual method, the fair value of the undelivered elements is deferred and the remaining portion of the contract fee is recognized as product revenue. If evidence of the fair value of one or more undelivered elements does not exist, all revenue is generally deferred and recognized when delivery of those elements occurs or when fair value can be established. When the undelivered element for which we do not have a fair value is support, revenue for the entire arrangement is bundled and recognized ratably over the support period. Revenue related to these arrangements is included in ratable product and related support and services revenue in the accompanying consolidated statements of operations. VSOE of fair value for elements of an arrangement is based upon the normal pricing and discounting practices for those services when sold separately and for support and updates is additionally measured by the renewal rate offered to the customer. Prior to the third quarter of 2005, we had not established VSOE for the fair value of support contracts provided to our reseller class of customers. As such, prior to the third quarter of 2005, we recognized all revenue on transactions sold through resellers ratably over the term of the support contract, typically one year. Beginning in the third quarter of 2005, we determined that we had established VSOE of fair value of support for products sold to resellers, and began recognizing product revenue upon delivery, provided the remaining criteria for revenue recognition had been met.
Our fees are typically considered to be fixed or determinable at the inception of an arrangement, generally based on specific products and quantities to be delivered. Substantially all of our contracts do not include rights of return or acceptance provisions. To the extent that our agreements contain such terms, we recognize revenue once the acceptance provisions or right of return lapses. Payment terms to customers generally range from net 30 to 60 days. In the event payment terms are provided that differ from our standard business practices, the fees are deemed to not be fixed or determinable and revenue is recognized when the payments become due, provided the remaining criteria for revenue recognition have been met.

We assess the ability to collect from our customers based on a number of factors, including credit worthiness of the customer and past transaction history of the customer. If the customer is not deemed credit worthy, we defer all revenue from the arrangement until payment is received and all other revenue recognition criteria have been met.
Stock-Based Compensation
Prior to January 1, 2006, we accounted for employee stock options using the intrinsic value method in accordance with Accounting Principles Board, or APB, Opinion No. 25,Accounting for Stock Issued to Employees, or APB 25, and Financial Accounting Standards Board Interpretation, or FIN 44,Accounting for Certain Transactions Involving Stock Compensation, an Interpretation of APB No. 25 and had adopted the disclosure only provisions of Statement of Financial Accounting Standards, or SFAS, No. 123,Accounting for Stock-Based Compensation (SFAS 123) and SFAS No. 148,Accounting for Stock-Based Compensation — Transition and Disclosure (SFAS 148) using the minimum value method.
In accordance with APB 25, stock-based compensation expense, which is a non-cash charge, resulted from stock option grants at exercise prices that, for financial reporting purposes, were deemed to be below the estimated fair value of the underlying common stock on the date of grant. Through December 31, 2005, we recorded deferred stock-based compensation relative to these options of approximately $9.9 million which is being amortized over the service period, which generally corresponds to the vesting period of the applicable options on a straight-line basis. During the years ended December 31, 2007, 2006 and 2005 respectively, we amortized $2.3 million, $2.4 million and $1.3 of deferred compensation expense, net of reversals for terminations, relative to these options.
Effective January 1, 2006, we adopted the fair value recognition provisions of SFAS No. 123(R),Share-Based Payment, using the prospective transition method, which requires us to apply the provisions of SFAS 123(R) to new awards granted, and to awards modified, repurchased or cancelled, after the effective date. Under this transition method, stock-based compensation expense recognized beginning January 1, 2006 is based on a combination of the following: (a) the grant-date fair value of stock option and employee stock purchase plan awards granted or modified after January 1, 2006; and (b) the amortization of deferred stock-based compensation related to stock option awards granted prior to January 1, 2006, which was calculated using the intrinsic value method as previously permitted under APB 25.
Under SFAS 123(R), we estimated the fair value of stock options granted using the Black-Scholes option-pricing formula and a single option award approach. This model utilizes the estimated fair value of common stock and requires that, at the date of grant, we use the expected term of the option, the expected volatility of the price of our common stock, risk free interest rates and expected dividend yield of our common stock. This fair value is then amortized on a straight-line basis over the requisite service periods of the awards, which is generally the vesting period. Options typically either vest with respect to 25% of the shares one year after the options’ vesting commencement date and the remainder ratably on a monthly basis over the following three years, or ratably on a monthly basis over four years. On September 20, 2006, we implemented our Employee Stock Purchase Plan, or Purchase Plan. Purchase Plan shares typically vest over two years, and include two purchase dates per year. The 2006 Purchase Plan became effective on the effective date of the registration statement relating to our IPO. Under the Purchase Plan, employees may purchase shares of common stock through payroll deductions at a price per share that is 85% of the lesser of the fair market value of our common stock as of the beginning of an applicable offering period or the applicable purchase date, with purchases generally every six months.

Weighted average fair value of grants | $8.04 – $12.87 | $15.02 – $15.52 | ||
The expected term represents the period that stock-based awards are expected to be outstanding. For the year ended December 31, 2007, we have elected to use the simplified method of determining the expected term of stock options as permitted by SEC Staff Accounting Bulletin 107. The computation of expected volatility for the year ended December 31, 2007 is based on the historical volatility of comparable companies from a representative peer group selected based on industry, financial and market capitalization data. As required by SFAS 123(R), management estimated expected forfeitures and is recognizing compensation costs only for those equity awards expected to vest.
As of December 31, 2007, total compensation cost related to stock options granted under SFAS 123(R) to employees and directors but not yet recognized was approximately $92.7 million, net of estimated forfeitures of $14.0 million. This cost will be amortized on a straight-line basis over the vesting period, which is typically 4 years. Amortization in the years ended December 31, 2007 and 2006 was $18.9 million and $4.3 million, respectively.
As of December 31, 2007, there was $9.1 million, net of estimated forfeitures of approximately $840,000, left to be amortized under our Purchase Plan, which will be amortized over the remaining Purchase Plan offering period, which is between 8 to 22 months. Amortization in the years ended December 31, 2007 and 2006 was $10.6 million and $2.5 million, respectively.
In accordance with SFAS 123(R), we have presented the cash-related tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options as financing cash flows for the year ended December 31, 2007. Tax benefits presented as financing cash flows for the year ended December 31, 2007 were $850,000. Tax benefits related to stock option exercises for options granted before the adoption of SFAS 123(R) are presented as operating cash flows.
Accounting for Income Taxes
We use the asset and liability method of accounting for income taxes in accordance with FASB Statement No. 109, Accounting for Income Taxes,Accounting for Income Taxes(SFAS 109). Under this method, income tax expenses or benefits are recognized for the amount of taxes payable or refundable for the current year and for deferred tax liabilities and assets for the future tax

consequences of events that have been recognized in our consolidated financial statements or tax returns. The measurement of current and deferred tax assets and liabilities are based on provisions of currently enacted tax laws. The effects of future changes in tax laws or rates are not contemplated.
As part of the process of preparing consolidated financial statements, we are required to estimate our income taxes and tax contingencies in each of the tax jurisdictions in which we operate prior to the completion and filing of tax returns for such periods. This process involves estimating actual current tax expense together with assessing temporary differences in the treatment of items for tax purposes versus financial accounting purposes that may create net deferred tax assets and liabilities.
We record a valuation allowance to reduce our deferred tax assets to the amount we believe is more likely than not to be realized. In assessing the need for a valuation allowance, we have considered our historical levels of income, expectations of future taxable income and on-going tax planning strategies. Because of the uncertainty of the realization of the deferred tax assets, we have recorded a full valuation allowance against our deferred tax assets. Realization of our deferred tax assets is dependent primarily upon future U.S. taxable income.
In June 2006, FASB issued interpretation No. 48, “Accounting for Uncertainty in Income Taxes-an interpretation of FASB Statement No. 109 (FAS No. 109)” (“FIN 48”). This interpretation prescribes a recognition threshold and measurement attribute for tax positions taken or expected to be taken in a tax return. This interpretation also provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The evaluation of a tax position in accordance with this interpretation is a two-step process. In the first step, recognition, the Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The second step addresses measurement of a tax position that meets the more-likely-than-not criteria. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in an increase in a liability for income taxes payable or a reduction of an income tax refund receivable, or a reduction in a deferred tax asset or an increase in a deferred tax liability or both. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be de-recognized in the first subsequent financial reporting period in which that threshold is no longer met. We adopted the provisions of FIN 48 on January 1, 2007 and have accrued approximately $157,000 as of December 31, 2007 as a result. We have also recognized a decrease in our deferred tax asset of $85,000 as of December 31, 2007. We have elected to record interest and penalties recognized in accordance with FIN 48 in the financial statements as income taxes.
Inventory Valuation
Inventory consists of hardware and related component parts and is stated at the lower of cost (on a first-in, first-out basis) or market. A portion of our inventory relates to evaluation units located at customer locations as some of our customers test our equipment prior to purchasing. Inventory that is obsolete or in excess of our forecasted demand is written down to its estimated realizable value based on historical usage, expected demand, and evaluation unit conversion rate and age. Inherent in our estimates of market value in determining inventory valuation are estimates related to economic trends, future demand for our products and technological obsolescence of our products. Inventory write-downs

are reflected as cost of product and amounted to approximately $1.1 million, $1.5 million and $772,000 for the years ended December 31, 2007, 2006 and 2005, respectively.
Allowances for Doubtful Accounts
We make judgments as to our ability to collect outstanding receivables and provide allowances for the portion of trade receivables when collection becomes doubtful. Provisions are made based upon a specific review of all significant outstanding invoices. For those invoices not specifically reviewed, provisions are provided at differing rates, based upon the age of the receivable. In determining these rates, we analyze our historical collection experience and current economic trends. The allowance for doubtful accounts was $734,000 and $472,000 at December 31, 2007 and 2006.
Software Development Costs
We account for costs incurred for computer software purchased or developed for internal use in accordance with Statement of position 98-1 (SOP 98-1),Accounting for the Cost of Computer Software Developed or Obtained for Internal Use.SOP 98-1 requires companies to capitalize qualifying computer software costs, which are incurred during the application development stage, and amortize them over the software’s estimated useful life.
We capitalized $2.1 million, $1.3 million and $69,000 in internal use software during the years ended December 31, 2007, 2006 and 2005, respectively. Amortization expense related to these assets totaled $343,000, $43,000 and $31,000 during the years ended December 31, 2007, 2006 and 2005, respectively.
Warranty Reserve
Upon shipment of products to our customers, we provide for the estimated cost to repair or replace products that may be returned under warranty. Our warranty period is typically 12 months from the date of shipment to the end-user customer for hardware and 90 days for software. For existing products, the reserve is estimated based on actual historical experience. For new products, the warranty reserve is based on historical experience of similar products until such time as sufficient historical data has been collected for the new product. Warranty reserves amounted to approximately $1.1 million and $735,000 at December 31, 2007 and 2006.
The following is a summary of the warranty reserve activity for the three years ended December 31, 2007:
(in thousands) | Beginning balance | Additions charged to operations | Warranty costs incurred | Ending balance | |||||||||
Warranty reserve analysis: | |||||||||||||
Year ended December 31, 2005 | $ | 45 | $ | 382 | (289 | ) | $ | 138 | |||||

Year ended December 31, 2007 | $ | 735 | $ | 1,983 | $ | (1,629 | ) | $ | 1,089 | ||||
Cash and Cash Equivalents
We consider all highly liquid investments purchased with original maturities at the date of purchase of three months or less to be cash equivalents. Cash and cash equivalents are stated at cost, which approximates fair value.

Marketable Securities
We determine the appropriate classification of investments in marketable securities at the time of purchase in accordance with Statement of Financial Accounting Standards No. 115,Accounting for Certain Investments in Debt and Equity Securities, and reevaluate such determination at each balance sheet date. Securities, which are classified as available for sale at December 31, 2007 and 2006, are carried at fair value, with the unrealized gains and losses reported as a separate component of stockholders’ equity. Unrealized gains and losses to date have been immaterial. Fair value is determined based on quoted market rates. Realized gains and losses and declines in value judged to be other-than-temporary on securities available for sale are included as a component of interest income. The cost of securities sold is based on the specific-identification method. Interest on securities classified as available for sale is included as a component of interest income.
Deferred Inventory Costs
When our products have been delivered, but the product revenue associated with the arrangement has been deferred as a result of not meeting the revenue recognition criteria in SOP 97-2, we also defer the related inventory costs for the delivered items in accordance with Accounting Research Bulletin 43,Restatement and Revision of Accounting Research Bulletins. Deferred inventory costs amounted to approximately $2.3 million and $3.5 million at December 31, 2007 and December 31, 2006, respectively, and are included in prepaid expenses and other current assets in the consolidated balance sheets.
Spares
We hold spare parts to service our customers who purchase support. We classify spare parts as other long term assets and amortize the spares over an estimated useful life of three years. At December 31, 2007 and 2006 our spare parts balance was $2.5 million and $876,000, respectively. In the years ended December 31, 2007 and 2006, we amortized $711,000 and $192,000, respectively, to cost of support and services relating to spares.
Concentrations of Risk
Financial instruments that are potentially subject to concentrations of credit risk consist primarily of cash, cash equivalents, marketable securities, and trade receivables. Investment policies have been implemented that limit investments to investment grade securities. The risk with respect to trade receivables is mitigated by credit evaluations we perform on our customers and by the diversification of our customer base. No customer represented more than 10% of our revenue for the years ended December 31, 2007, 2006 or 2005.
We outsource the production of our hardware to third-party manufacturing facilities. We rely on purchase orders or long-term contracts with our contract manufacturers. At December 31, 2007, we had no long-term contractual commitment with any manufacturer; however, we did have a 90 day commitment totaling $6.1 million.
Foreign Currency Translation
While the majority of our revenue contracts are denominated in United States dollars, we incur certain operating expenses in various foreign currencies. The functional currency of our foreign

operations is the local country’s currency. Consequently, expenses of operations outside the United States are translated into United States dollars using average exchange rates for the period reported while assets and liabilities of operations outside the United States are translated into United States dollars using end of period exchange rates. Foreign currency translation adjustments not affecting net income are included in stockholders’ equity as a component of accumulated other comprehensive income (loss) in the accompanying consolidated balance sheets. The revaluation effect of foreign currency fluctuations on intercompany balances is recorded to foreign currency gain (loss) and included in other income (expense) in the accompanying consolidated statements of operations. Foreign currency losses included in other income (expense) for the years ended December 31, 2007, 2006 and 2005 were $349,000, $219,000 and $63,000, respectively.
Comprehensive Income (Loss)
Comprehensive income (loss) consists of other comprehensive income and net income (loss). Other comprehensive income includes certain changes in equity that are excluded from net loss. Specifically, cumulative foreign currency translation adjustments and unrealized losses on marketable securities are included in accumulated other comprehensive income. Comprehensive loss has been reflected in the consolidated statements of convertible preferred stock and stockholders’ equity (deficit).
Accumulated other comprehensive income (loss) was $53,000 and ($16,000) at December 31, 2007 and 2006, resulting primarily from foreign currency translation adjustments.
Impairment of Long-Lived Assets
We review long-lived assets and identifiable intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of these assets may not be recoverable. We assess these assets for impairment based on estimated undiscounted future cash flows from these assets. If the carrying value of the assets exceeds the estimated future undiscounted cash flows, a loss is recorded for the excess of the asset’s carrying value over the fair value. To date we have not recognized any impairment loss for long-lived assets.
Advertising
All advertising costs are expensed as incurred. Advertising expenses were $2.4 million, $295,000 and $836,000 for the years ended December 31, 2007, 2006 and 2005.
Research and Development
All costs to develop our products are expensed as incurred. Software development costs are capitalized beginning when a product’s technological feasibility has been established and ending when a product is available for general release to customers. Generally, our products are released soon after technological feasibility has been established. As a result, costs subsequent to achieving technological feasibility have not been significant and all software development costs have been expensed as incurred.
Freestanding Preferred Stock Warrants
Freestanding warrants and other similar instruments related to shares that are redeemable are accounted for in accordance with FASB Statement No. 150,Accounting for Certain Financial

Instruments with Characteristics of Both Liabilities and Equity. On March 31, 2003, we issued a warrant for the purchase of 32,967 shares of Series A convertible preferred stock with an exercise price of $0.455 per share. On June 7, 2004, we issued warrants for the purchase of 100,000 shares of Series B convertible preferred stock with an exercise price of $0.836 per share. Under Statement No. 150, these warrants that were related to our convertible preferred stock were classified as liabilities on the consolidated balance sheet. The warrants were subject to re-measurement at each balance sheet date and any change in fair value was recognized as a component of other income (expense), net. Subsequent to the IPO and the associated conversion of our outstanding convertible preferred stock to common stock, the warrants were reclassified to common stock and additional paid-in-capital and are no longer subject to re-measurement. During the year ended December 31, 2006, the warrants to purchase 100,000 common shares were exercised. During the year ended December 31, 2007, the warrants to purchase 32,967 shares were exercised.
Prior to the adoption of Statement No. 150, we accounted for freestanding warrants for the purchase of our convertible preferred stock under EITF Issue No. 96-18,Accounting for Equity Instruments That Are Issued to Other Than Employees for Acquiring, or in Conjunction with Selling Goods or Services.We accounted for the cumulative effect of the change in accounting principle as of the beginning of the third quarter of 2005. The impact consisted of a $280,000 cumulative charge for adoption as of July 1, 2005, reflecting the fair value of the warrants as of that date.
2. NET INCOME (LOSS) PER COMMON SHARE
Basic net income (loss) per common share is computed by dividing net income (loss) by the weighted average number of vested common shares outstanding during the period. Diluted net income (loss) per common share is computed by giving effect to all potential dilutive common shares, including options, common stock subject to repurchase, warrants and convertible preferred stock.
The following table sets forth the computation of income (loss) per share:

3. CASH, CASH EQUIVALENTS AND MARKETABLE SECURITIES
Cash, Cash Equivalents and Marketable Securities
Cash and cash equivalents consist primarily of highly liquid investments in time deposits held at major banks, commercial paper, United States government agency discount notes, money market mutual funds and other money market securities with original maturities at the date of purchase of 90 days or less. The carrying value of cash and cash equivalents at December 31, 2007 and 2006 was approximately $163.0 million and $105.3 million, and the weighted average interest rates were 5.0% and 5.3%, respectively. The carrying value approximates fair value at December 31, 2007 and 2006.
Marketable securities, which are classified as available for sale at December 31, 2007, are carried at fair value, with the unrealized gains and losses reported as a separate component of stockholders’ equity. Marketable securities consist of government sponsored enterprise obligations and corporate bonds and notes. As of December 31, 2007 and 2006, the marketable securities are recorded at amortized cost which approximates fair market value. All investments mature in one year or less.

Proceeds from the sales of available-for-sale securities were $39.0 million and $0 in the years ended December 31, 2007 and 2006, respectively. There were no gross realized gains or losses recorded on those sales during 2007 and 2006, respectively. Net unrealized holding losses on available-for-sale securities in the amount of $15,000 and $0 as of December 31, 2007 and 2006, respectively, have been included in accumulated other comprehensive income.
We evaluate investments with unrealized losses to determine if the losses are other than temporary. The gross unrealized losses were primarily due to changes in interest rates. We have determined that the gross unrealized losses at December 31, 2007 are temporary. In making this
determination, we considered the financial condition and near-term prospects of the issuers, the

magnitude of the losses compared to the investments’ cost, the length of time the investments have been in an unrealized loss position and our ability to hold the investment to maturity. Investments with unrealized losses have been in an unrealized loss position for less than a year.
Restricted Cash
Pursuant to certain lease agreements and as security for our merchant services agreement with our financial institution, we are required to maintain cash reserves, classified as restricted cash. Current restricted cash totaled $142,000 and $121,000 at December 31, 2007 and 2006, respectively. Long-term restricted cash totaled $3.5 million and $1.5 million at December 31, 2007 and 2006, respectively. Long-term restricted cash is included in other assets in the consolidated balance sheets and consists primarily of funds held as collateral for letters of credit for the security deposit on the leases of our corporate headquarters. The long-term restricted cash is restricted until the end of the lease terms on August 30, 2010 and July 31, 2014.

5. FIXED ASSETS
Fixed assets are stated at cost. Depreciation is calculated using the straight-line method over the estimated useful lives of the respective assets, which is typically two to five years. Leasehold improvements are amortized using the straight-line method over the shorter of the lease term or estimated useful life of the asset. Repair and maintenance costs are expensed as incurred.

Deferred revenue, non-current | 6,634 | 2,245 | ||||
Total deferred revenue | $ | 33,479 | $ | 19,082 | ||
Deferred product revenue relates to arrangements where not all revenue recognition criteria have been met. Deferred support revenue represents customer payments made in advance for annual support contracts. Support contracts are typically billed on a per annum basis in advance and revenue is recognized ratably over the support period. Deferred ratable product and related support and services revenue consists of deferred revenue on transactions where VSOE of fair value of support had not been established and the entire arrangement is being recognized ratably over the support period. Deferred revenue, non-current consists primarily of customer payments made in advance for support contracts with terms of more than 12 months.
7. GUARANTEES
Our agreements with customers, as well as our reseller agreements, generally include certain provisions for indemnifying customers and resellers and their affiliated parties against liabilities if our products infringe a third party’s intellectual property rights. To date, we have not incurred any material costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in our consolidated financial statements.
As permitted or required under Delaware law and to the maximum extent allowable under that law, we have certain obligations to indemnify our officers, directors and certain key employees for certain events or occurrences while the officer, director or employee is or was serving at our request in such capacity. These indemnification obligations are valid as long as the director, officer or employee

acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. The maximum potential amount of future payments we could be required to make under these indemnification obligations is unlimited; however, we have a director and officer insurance policy that mitigates our exposure and enables us to recover a portion of any future amounts paid.
8. LEASE COMMITMENTS
We lease our facilities under non-cancelable operating lease agreements. Future minimum commitments for these operating leases in place as of December 31, 2007 with a remaining non-cancelable lease term in excess of one year are as follows:

The terms of certain lease agreements provide for rental payments on a graduated basis. We recognize rent expense on the straight-line basis over the lease period and have accrued for rent expense incurred but not paid. Rent expense under operating leases was $5.3 million, $2.1 million, and $763,000 for the years ended December 31, 2007, 2006 and 2005, respectively.
On September 26, 2006, we entered into an Agreement of Sublease, or Sublease, for new corporate headquarters, and on March 21, 2007 entered into another lease agreement to expand our corporate headquarters as well as extend the term of the existing Sublease mentioned above. The terms of the leases are from February 1, 2007 and March 31, 2007, respectively, to July 31, 2014. The aggregate minimum lease commitment for the combined leases is $21.3 million and is included in the table above. We have entered into two letters of credit totaling $3.0 million to serve as security deposits for the leases, which is included in other assets in the consolidated balance sheet.
On July 3, 2007, we entered into a lease agreement for office space in Sunnyvale, California. The term of the lease is for five years and seven months commencing on January 1, 2008. The aggregate minimum lease commitment is $4.7 million and is reflected in the table above. On July 2, 2007, we entered into a letter of credit in the amount of $500,000 to serve as the security deposit for the lease.
9. COMMON STOCK
In July 2002, our board of directors adopted the 2002 Stock Plan, or 2002 Plan. In September 2006, all shares of common stock available for grant under the 2002 Plan transferred to the 2006 Equity Incentive Plan, or 2006 Plan.

Table of Contents
RIVERBED TECHNOLOGY, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
In April and May 2006, our board of directors approved the 2006 Plan, the Purchase Plan and the 2006 Director Stock Option Plan, which became effective upon our IPO.
The Plans provide for automatic replenishments as follows:
| Ÿ | 2006 Plan—increased on January 1 of each year for five years, beginning in 2007, by a number equal to the lesser of (i) 4,000,000 shares or (ii) 5% of the shares of common stock outstanding at that time or (iii) the number of shares determined by the Board. |
| Ÿ | 2006 Employee Stock Purchase Plan—increased on January 1 of each year by a number of shares equal to the lesser of (i) 750,000 shares or (ii) 1% of the shares of common stock outstanding at that time or (iii) the number of shares determined by the Board. |
| Ÿ | 2006 Director Option Plan—increased on January 1 of each year by 250,000 shares. |
Options issued under our stock option plans are generally for periods not to exceed 10 years and are issued at the fair value of the shares of common stock on the date of grant as determined by the Board of Directors. Following the IPO, the fair value of our common stock is determined by the last sale price of such stock on the Nasdaq Global Market. Options typically either vest with respect to 25% of the shares one year after the options’ vesting commencement date and the remainder ratably on a monthly basis over the following three years, or ratably on a monthly basis over four years. Options granted under the 2002 Plan prior to May 31, 2006 have a maximum term of ten years. Beginning May 31, 2006, options granted under the 2002 Plan had a maximum term of seven years. Options granted under the 2006 Plan had a maximum term of seven years and options granted under the 2006 Director Option Plan had a maximum term of 10 years. Prior to March 28, 2006, employees in the United States had the right to exercise their options granted under the 2002 Plan prior to vesting. For options granted beginning March 28, 2006, optionees may only exercise vested shares. Any unvested stock issued under the 2002 Plan is subject to repurchase by us. Grants made pursuant to the 2006 Plan do not provide for the early exercise of options.
The Purchase Plan became effective on the effective date of the registration statement relating to our IPO. Under the Purchase Plan, employees may purchase shares of common stock through payroll deductions at a price per share that is 85% of the lesser of the fair market value of our common stock as of the beginning of an applicable offering period or the applicable purchase date, with purchases generally every six months. Employees’ payroll deductions may not exceed 15% of their compensation. Employees may purchase up to 2,000 shares per purchase period provided that the value of the shares purchased in any calendar year does not exceed IRS regulations. As of December 31, 2007, 1,428,033 shares were available under the Purchase Plan.

As of December 31, 2007, we had net operating loss carryforwards for federal, state and foreign income tax purposes of $15.1 million, $16.9 million and $3.7 million, respectively. We also had federal and state research and development tax credit carryforwards of approximately $2.9 million and $2.8 million, respectively.
Realization of deferred tax assets is dependent upon future earnings, if any, the timing and amount of which are uncertain. Accordingly, the net deferred tax assets were fully offset by a valuation allowance. If not utilized, the federal and state net operating loss and tax credit carryforwards will expire between 2013 and 2026 while the foreign net operating losses do not expire. Due to prior changes in ownership in 2002 and 2003, we have approximately $425,000 and $393,000 of federal and state net operating losses carryforwards which are subject to an annual limitation on utilization. In addition, we also have approximately $152,000 and $146,000 of federal and state research and development tax credit carryforwards, which are subject to an annual limitation.
We track the portion of our federal and state net operating loss carryforwards attributable to stock option benefits in a separate memo account pursuant to SFAS 123(R). Therefore, these amounts are no longer included in gross or net deferred tax assets. Pursuant to SFAS 123(R), footnote 82, the benefit of these net operating loss and tax credit carryforwards will only be recorded to equity when they reduce cash taxes payable. We elected to use the “with-and-without” approach for utilizing the tax benefits of stock option exercises under SFAS 123(R). These benefits would result in a credit to additional paid-in-capital when they reduce income taxes payable. We recognized a reduction in taxes payable for the tax benefit of stock option exercises during 2007 of $4.3 million.

Included in the unrecognized tax benefits of $298,000 at December 31, 2007 was approximately $242,000 of tax benefits that, if recognized, would reduce our annual effective tax rate. We did not accrue for any interest and penalty associated with the uncertain tax position. We do not expect our unrecognized tax benefits to change significantly over the next 12 months. The statute of limitations for federal, state, and UK tax purposes are generally three, four, and three years respectively; however, we continue to carryover tax attributes prior to these periods for federal and state purposes, which would still be open for examination by the respective tax authorities. All years since our inception are open to tax examinations.
11. SEGMENT INFORMATION
FASB Statement No. 131,Disclosures about Segments of an Enterprise and Related Information, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer. Our Chief Executive Officer reviews financial information presented on a consolidated basis, accompanied by information about revenue by geographic region for purposes of allocating resources and evaluating financial performance. We have one business activity and there are no segment managers who are held accountable for operations, operating results and plans for levels or components below the consolidated unit level. Accordingly, we are considered to be in a single reporting segment and operating unit structure.
Revenue by geography is based on the billing address of the customer. The following table sets forth revenue and long-lived assets by geographic area:

13. LEGAL MATTERS
On October 9, 2007, Quantum Corporation served us with a lawsuit, filed in the United States District Court, Northern District of California, alleging patent infringement of United States Patent No. 5,990,810 (the “‘810 patent”). Quantum seeks unspecified damages and injunctive relief.
On November 13, 2007, we counterclaimed against Quantum Corporation and served Quantum with a lawsuit, filed in the United States District Court, Northern District of California, alleging patent infringement of United States Patent No. 7,116,249. Trial on our claim against Quantum is currently scheduled to begin February 2, 2009.
On January 9, 2008, we moved to dismiss Quantum’s complaint for infringement in the United States District Court, Northern District of California, for lack of standing. Our motion was granted by the Court on February 4, 2008.
On January 9, 2008, we filed an action in the United States District Court, Delaware, against Quantum and certain of its subsidiaries seeking a declaratory judgment of non-infringement and invalidity with respect to the ‘810 patent.
On or about February 13, 2008, Quantum filed a lawsuit against us in the United States District Court, Northern District of California, alleging patent infringement of United States Patent No. 6,622,164 (the “‘164 Patent”). We have not yet been served with this lawsuit.
On February 14, 2008, Quantum moved to dismiss our complaint in the United States District Court, Delaware or, in the alternative, to transfer the action to the United States District Court, Northern District of California. In addition, Quantum moved for leave to file an amended counterclaim in the United States District Court, Northern District of California to add claims for infringement of the ‘810 Patent and the ‘164 Patent.
We believe that Quantum’s actions against us are without merit and we intend to vigorously defend against these claims. We currently are unable to estimate the possible loss or range of loss associated with these actions.
From time to time, we are involved in various legal proceedings, claims and litigation arising in the ordinary course of business. There are no other currently pending legal proceedings at December 31,

For the year ended December 31, 2007, we recognized $787,000 of revenue from a customer who, as of December 31, 2007, held approximately 10% of our stock. As of December 31, 2007, we had accounts receivable from this customer of approximately $559,000.
15. NEW ACCOUNTING PRONOUNCEMENTS
In September 2006, the FASB issued Statement No. 157,Fair Value Measurements,which defines fair value, establishes a framework for measuring fair value and expands fair value measurement disclosures. SFAS 157 is effective for fiscal years beginning after November 15, 2007. We are currently evaluating the impact of the pending adoption of SFAS 157 on our consolidated financial statements.
In February 2007, the FASB issued Statement No. 159,The Fair Value Option for Financial Assets and Financial Liabilities, including an amendment of FASB Statement No. 115, which allows an entity the irrevocable option to elect fair value for the initial and subsequent measurement for certain financial assets and liabilities under an instrument-by-instrument election. Subsequent measurements for the financial assets and liabilities an entity elects to fair value will be recognized in earnings. SFAS 159 also establishes additional disclosure requirements. SFAS 159 is effective for fiscal years beginning after November 15, 2007, with early adoption permitted provided that the entity also adopts SFAS 157. We are currently evaluating the impact of the adoption of SFAS 159 on our consolidated financial statements.
In June 2007, the FASB ratified EITF 07-3,Accounting for Non-Refundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities.EITF 07-3 requires that non-refundable advance payments for goods or services that will be used or rendered for future research and development activities be deferred and capitalized and recognized as an expense as the goods are delivered or the related services are performed. EITF 07-3 is effective, on a prospective basis, for fiscal years beginning after December 15, 2007. We are currently evaluating the impact of the pending adoption of EITF 07-3 on our consolidated financial statements.

(a.) Management’s Report on Internal Control Over Financial Reporting
Our management is responsible for establishing and maintaining adequate internal control over our financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. There are inherent limitations in the effectiveness of any internal control, including the possibility of human error and the circumvention or overriding of controls. Accordingly, even any effective internal control can provide only reasonable assurance with respect to financial statement preparation. Further, because of changes in conditions, the effectiveness of any internal control may vary over time.
Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our internal control over financial reporting as of December 31, 2007. In making this assessment, management used the framework set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) inInternal Control-Integrated Framework.
Based on our assessment, using those criteria, our management concluded that, as of December 31, 2007, our internal control over financial reporting was effective.

(b.) Changes in Internal Control Over Financial Reporting
There was no change in our internal control over financial reporting that occurred during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
(c.) Evaluation of Disclosure Controls and Procedures
Based on our management’s evaluation (with the participation of our principal executive officer and principal financial officer), as of December 31, 2007, the end of the period covered by this report, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act) were effective to ensure that information required to be disclosed by us in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.
