Products and Services

Data Storage

Brocade’s storage networking products and services are designed to help customers reduce the cost and complexity of managing business information within a shared data storage environment, while enabling high levels of availability of mission critical business applications. In addition, Brocade’s products and services assist customers in the development and delivery of storage and server consolidation, disaster recovery and data security, and in meeting compliance issues regarding data management. Customers use Brocade’s products to build storage area networks (“SAN”s), which we refer to as “fabrics.” Brocade’s products are generally used in conjunction with servers and storage subsystems, SAN interconnection components such as host bus adapters (“HBAs”), and server and storage management software applications and tools. By utilizing a shared storage, or networked storage solution, enterprises of all types and sizes can more easily share and consolidate server and storage resources, centralize and simplify data management, scale and provision storage resources more effectively, and improve application efficiency, performance and availability. As a result, these enterprises are able to better utilize IT assets, improve productivity of IT personnel, reduce capital and operational expenditures, and more reliably and securely store, manage and administer business information.

Brocade’s family of Fibre Channel SAN backbones, directors, fabric and embedded switches provide interconnections, bandwidth and high-speed routing of data between servers and storage devices. Product models range from entry-level 8-port fabric switches to 896-port directors with multiple options, addressing the needs of small departments and global enterprises alike. These high-performance solutions are available to support requirements both for open systems and mainframe operations. Switches and directors support key applications such as data backup, remote mirroring and high-availability clustering, as well as high-volume transaction processing applications such as enterprise resource planning and data warehousing. Brocade’s storage networking products have been designed to meet the storage networking needs of end-users in environments ranging from small and medium-sized businesses to large enterprises with storage network fabrics that scale to thousands of ports, spread across multiple locations around the world. Brocade’s storage networking products also include HBAs, which connect host computers to a Fibre Channel (“FC”) network.

Brocade offers a variety of fabric extension, switching and routing solutions that are designed to connect two or more data centers over long distances to enhance business continuity and disaster recovery. Brocade’s

(“Dell”), which enables IBM and Dell to rebrand and sell certain of Brocade’s enterprise Ethernet networking products. EMC has also recently expanded its partnership with Brocade which enables EMC to resell Ethernet networking products.

Geographic Information

For the year ended October 30, 2010, domestic and international revenues were approximately 64% and 36% of total net revenues, respectively. For the year ended October 31, 2009, domestic and international revenues were approximately 65% and 35% of total net revenues, respectively. For the year ended October 25, 2008, domestic and international revenues were approximately 63% and 37% of total net revenues, respectively. International revenues primarily consist of sales to customers in Western Europe, the greater Asia Pacific region and Japan. For the year ended October 30, 2010, international revenues increased as a percentage of total net revenues primarily due to growth in the Asia Pacific region. For the year ended October 31, 2009, international revenues decreased as a percentage of total net revenues primarily as a result of Brocade’s acquisition of Foundry Networks, Inc. (“Foundry”), which had a higher concentration of its customer base in North America.

Revenues are attributed to geographic areas based on where Brocade’s products are shipped. However, certain OEM customers take possession of Brocade’s products domestically and then distribute these products to their international customers. Because Brocade accounts for all of those OEM revenues as domestic revenues, Brocade cannot be certain of the extent to which its domestic and international revenue mix is impacted by the practices of its OEM customers. Nevertheless, data provided by OEM customers indicate that international customers may account for a higher percentage of end-user demand than that indicated by Brocade’s mix of domestic and international revenues.

The majority of Brocade’s assets as of October 30, 2010 were attributable to its United States operations. For additional geographic information on Brocade’s revenues and long lived assets, see Note 16 “Segment Information,” of the Notes to Consolidated Financial Statements, which is incorporated herein by reference. Also, for a discussion of the risks attendant to Brocade’s foreign operations, see Part I, Item 1A. Risk Factors of this Form 10-K, which is incorporated herein by reference.

This acquisition expanded Brocade’s professional service offerings and was consistent with its goal of building an end-to-end services portfolio.

On January 29, 2007, Brocade completed its acquisition of McDATA Corporation (“McDATA”), a provider of storage networking and data infrastructure solutions. McDATA is a wholly-owned subsidiary of Brocade. This

8

acquisition enabled Brocade to build stronger relationships with its customers and partners, and provide greater scale and efficiencies to accelerate its growth.

On January 5, 2007, Brocade completed its acquisition of Silverback Systems, Inc. (“Silverback”), a privately held provider of network acceleration technology. This acquisition further enabled Brocade to provide Ethernet-based solutions for data center networks.

From time to time, Brocade has made equity investments in companies that develop technology or provide services that are complementary to or broaden the markets for its products or services and further its business objectives.

Research and Development

The industry in which Brocade competes is subject to rapid technological developments, evolving industry standards, changes in customer requirements, new product introductions and consolidation. As a result, Brocade’s success depends, in part, on its ability to continue to enhance its existing solutions and to develop and introduce new solutions that improve performance and reduce the total cost of ownership in the storage environment. Brocade has invested significantly in product research and development. Brocade continues to enhance and extend its products and increase the speed, performance and port-density of its switching platform. Brocade also continues to expand the value-added services of its intelligent platform to further simplify storage management and to enable more functionality for end-user customers, OEM partners and application partners.

Brocade products are designed to support current industry standards and may continue to support emerging standards that are consistent with its product strategy. Brocade products have been designed around a common platform architecture which facilitates the product design, development and testing cycle, and reduces the time to market for new products and features. Brocade intends to continue to leverage this common architecture to develop and introduce additional hardware and software products and enhancements in the future.

Brocade’s product development process includes the certification of certain of its products by its OEM partners. During this process, Brocade supports its OEM partners in the testing of its new products to ensure they meet quality, functionality and inoperability requirements. The process is completed once the OEM partner has certified the product and announced general availability of that product to their customers.

For the years ended October 30, 2010, October 31, 2009 and October 25, 2008, Brocade’s research and development expenses totaled $354.3 million, $354.8 million and $255.6 million, respectively. All expenditures for research and development costs have been expensed as incurred. In fiscal year 2011, Brocade expects to increase its level of investment, in absolute dollars, in research and development.

Competition

The market for networking solutions is intensely competitive. In particular, Cisco Systems, Inc. (“Cisco”) maintains a large position in the Ethernet and SAN markets and a number of its products compete directly with Brocade’s products. Brocade also competes with other companies, such as Alcatel-Lucent, Arista Networks, Enterasys Networks, Inc., Extreme Networks, Inc., F5 Networks, Inc., Force10 Networks, Inc., HP, Huawei Technologies Co. Ltd., IBM, Juniper Networks, Inc. (“Juniper”) and Oracle Corporation. Some of Brocade’s current and potential competitors have greater market leverage, longer operating histories, greater financial, technical, sales, marketing and other resources, more name recognition and larger installed customer bases.

In addition, Brocade faces significant competition from providers of storage networking products for interconnecting servers and storage. These principal competitors include Cisco and QLogic Corporation (“QLogic”). Brocade also faces other competitors in markets adjacent to the SAN market, such as Cisco and F5 Networks, Inc. in the Layers 4-7 networking market and QLogic and Emulex Corporation in the HBA/CNA markets.

9

New competitors are likely to emerge from the existing Ethernet networking companies in the market as the FCoE standard becomes finalized and additional products come to market. These competitors are likely to use emerging technologies and various routes-to-market to compete with Brocade. In addition, Brocade’s OEM partners, who also have relationships with some of Brocade’s current competitors, could become new competitors by developing, acquiring or introducing products that compete with Brocade’s product offerings, by choosing to sell its competitors’ products instead of Brocade’s products, or by offering preferred pricing or promotions on competitors’ products. Competitive pressure will also likely intensify as technology trends may impact long-standing alliances, partnerships and go-to-market routes.

In addition, as the networking solutions market evolves, additional technologies may become available for interconnecting servers and storage. To the extent that products based upon these technologies provide the ability to connect network servers and storage and support high-performance storage applications, they are likely to compete with Brocade’s current and future products. Competitive technologies include, but are not limited to, emerging products based on 1 Gigabit Ethernet (“GbE”), 10 GbE, 100 GbE, FCoE, Data Center Bridging (“DCB”), InfiniBand and Internet Small Computer System Interface (“iSCSI”) protocols, as well as other storage solutions such as Network Attached Storage and Direct Attached Storage. In addition, networking companies, manufacturers of networking equipment, and other companies may develop competitive products and technologies. Brocade’s OEM partners or other partners could also develop and introduce products that compete with Brocade’s product offerings. Brocade believes the competitive factors in this market include product performance and features, product reliability, price, size, extent of installed base, ability to meet delivery schedules, customer service, technical support and distribution channels.

Manufacturing

Brocade has manufacturing arrangements with Hon Hai Precision Industry Co., Ltd. (“Foxconn”), Sanmina-SCI Corporation (“Sanmina”), Asteel Flash Group (“Flash”), Accton Wireless Broadband Corporation (“Accton”), Motorola, Inc. (“Motorola”) and Quanta Computer Incorporated (“Quanta”) (collectively the “CMs”) under which Brocade provides product forecasts and places purchase orders in advance of the scheduled delivery of products to Brocade’s customers. The required lead time for placing orders with the CMs depends on the specific product. The CMs invoice Brocade based on prices and payment terms mutually agreed upon and set forth in purchase orders Brocade issues to them. Although the purchase orders Brocade places with its CMs are cancelable, the terms of the agreements require Brocade to purchase all inventory materials not returnable, usable by, or sold to other customers of the CMs. In addition, Flextronics International Ltd. (“Flextronics”) is Brocade’s service repair operations provider.

Brocade uses the CMs for final turnkey product assembly; however, Brocade also maintains key component selection and qualification expertise internally. Brocade designs and develops the key components of its products, including application-specific integrated circuits (“ASICs”), operating system and other software, as well as certain details in the fabrication and enclosure of its products. In addition, Brocade determines the components that are incorporated into its products and selects appropriate suppliers of those components.

Although Brocade uses standard parts and components for its products where possible, Brocade’s CMs currently purchase, on Brocade’s behalf, several key components used in the manufacture of its products from single or limited supplier sources. Brocade’s principal single source components include ASICs, built by third-parties based on Brocade’s designs, and Brocade’s principal limited source components include memory, certain oscillators, microprocessors, certain connectors, certain logic chips, certain power supplies, enclosures, programmable logic devices, certain printed circuit boards, certain optical components, packet processors and switching fabrics. In addition, Brocade licenses certain software from third parties that is incorporated into its fabric operating system and other software. See Part I, Item 1A. Risk Factors of this Form 10-K, which is incorporated herein by reference.

Brocade is subject to various environmental and other regulations governing product safety, materials usage, packaging and other environmental impacts in the various countries where its products are sold. For example, many of Brocade’s products are subject to laws and regulations that restrict the use of lead, mercury, hexavalent chromium, cadmium and other substances, and require producers of electrical and electronic equipment to assume responsibility for collecting, treating, recycling and disposing of its products when they have reached the end of their useful life. In Europe, substance restrictions apply to products Brocade sells, and certain of Brocade’s OEM partners require compliance with these or more stringent requirements. Recycling, labeling, financing and related requirements also apply to products Brocade sells in Europe. China has also enacted similar legislation with similar requirements for Brocade’s products or its OEM partners. Brocade may be required to redesign its products to ensure that they comply with any new requirements as well as related requirements imposed by its OEM customers. Brocade also continues to work with its suppliers to ensure they provide Brocade with compliant materials, parts and components. Various other countries and states in the United States have issued, or are in the process of issuing, other environmental regulations that may impose additional restrictions or obligations and require further changes to Brocade’s products.

Patents, Intellectual Property and Licensing

Brocade relies on a combination of patent, copyright, trademark and trade secret laws, and contractual restrictions on disclosure to protect its intellectual property rights in these proprietary technologies. Despite these precautions, the measures Brocade undertakes may not prevent misappropriation or infringement of its proprietary technology. These measures also may not preclude competitors from independently developing products with functionality or features similar to its products.

Brocade maintains a program to identify and obtain patent protection for its selected inventions. As of December 10, 2010, Brocade has 311 patents in the United States and 13 patents in various foreign countries (based on certain U.S. patents or patent applications) that are currently in force and has approximately 317 patent applications pending in the United States and approximately 11 patent applications pending in various foreign countries (based on certain U.S. patents or patent applications). The normal expiration dates of Brocade’s issued patents in the United States range from 2010 to approximately 2027. Although Brocade has patent applications pending, there can be no assurance that patents will be issued from pending applications or that claims allowed on any future patents will be sufficiently broad to protect its technology.

Many of Brocade’s products are designed to include software or other intellectual property licensed from third parties. While it may be necessary in the future to seek or renew licenses relating to various aspects of its products, Brocade believes that such licenses generally could be obtained on commercially reasonable terms. However, failure to obtain such licenses on commercially reasonable terms could materially harm Brocade’s business. See Part I, Item 1A. Risk Factors of this Form 10-K, which is incorporated herein by reference.

From time to time, third parties have asserted patent, copyright and trade secret rights to technologies and standards that are important to Brocade. Third parties assert patent infringement claims against Brocade from time to time in the form of letters, lawsuits and other forms of communication. In addition, from time to time, Brocade receives notification from customers claiming that they are entitled to indemnification or other obligations from Brocade related to infringement claims made against them by third parties.

Seasonality

Historically, our first and fourth fiscal quarters are seasonally stronger quarters from a revenue perspective than our second and third fiscal quarters.

Backlog

Brocade’s business is characterized by short lead-time orders and fast delivery schedules. Sales of its products are generally made pursuant to contracts and purchase orders that are cancelable without significant penalties. These commitments are subject to price negotiations and to changes in quantities of products and delivery schedules in order to reflect changes in customers’ requirements and manufacturing availability. In addition, actual shipments depend on the manufacturing capacity of suppliers and the availability of products from such suppliers. As a result of the foregoing factors, Brocade does not believe that backlog at any given time is a meaningful indicator of its ability to achieve any particular level of revenue or financial performance.

Employees

As of October 30, 2010, Brocade had 4,651 employees. Brocade has not experienced any work stoppages and considers its relations with its employees to be good. Brocade’s employees are currently located in the United States headquarters in San Jose, California, as well as facilities in Broomfield, Colorado, Herndon, Virginia, Plymouth, Minnesota, the European headquarters in Geneva, Switzerland, the Asia Pacific headquarters in Singapore, and other offices throughout North America, Europe, Asia Pacific, Japan and Central and South America.

Item 1A. Risk Factors

Intense competition in the market for networking solutions could prevent Brocade from increasing or maintaining revenue, profitability and cash flows with respect to its networking solutions.

The networking market is becoming increasingly competitive. While Cisco maintains a dominant position in the Ethernet networking market, other companies have strengthened their networking portfolio through acquisitions, including HP’s acquisition of 3Com and IBM’s acquisition of Blade Network Technologies. Both HP and IBM are important OEM partners for Brocade in the Fibre Channel switching market, yet also are competitive with Brocade in other respects. EMC, one of Brocade’s top OEM customers in terms of Fibre Channel sales and a go-to-market and technology partner since 1997, has formed a coalition with Cisco and VMware called the “Virtual Computing Environment” (VCE) through which VCE and its business partners would sell packaged “cloud computing” and data center virtualization solutions. Further, Cisco and EMC announced a joint venture, which is designed to serve as a support and services arm of VCE. The above-referenced acquisition and business partnerships demonstrate the increasingly complex nature of relationships within the networking industry.

Other competitors in the Ethernet networking market include Arista Networks, Alcatel-Lucent, Enterasys Networks, Inc., Extreme Networks, Inc., F5 Networks, Inc., Force10 Networks, Inc., Huawei Technologies Co. Ltd., Juniper Networks, Inc. and most recently, Oracle Corporation through its acquisition of Sun Microsystems, Inc. Brocade also competes with Cisco and QLogic Corporation in the Fibre Channel switching market and with QLogic and Emulex Corporation in the server connectivity or HBA market. Some of these competitors have greater market leverage, longer operating histories, greater financial, technical, sales, marketing and other resources, more name recognition and larger installed customer bases. Brocade’s competitors could also adopt more aggressive pricing policies than Brocade. Brocade believes that competition based on price may become more aggressive than it has traditionally experienced. As a result of these factors, Brocade’s competitors could also devote greater resources to the development, promotion and sale of their products than Brocade and, as a result, may be able to respond more quickly to changes in customer or market requirements. Brocade’s failure to successfully compete in the market would harm Brocade’s business and financial results.

In addition, the advent and customer adoption of new technologies such as Fibre Channel over Ethernet (“FCoE”) and Data Center Bridging (“DCB”), formerly called Converged Enhanced Ethernet (“CEE”), may displace existing solutions in actual customer implementations, leading to erosion of the total addressable market (“TAM”) for Fibre Channel products of the type that Brocade currently delivers. While Brocade offers FCoE products and has recently introduced a new family of DCB products as part of its overall networking portfolio, the potential for reduction of Fibre Channel TAM where Brocade is a market leader may harm Brocade’s business and financial results.

Brocade’s future revenue growth depends on its ability to introduce new products and services on a timely basis and achieve market acceptance of these new products and services.

The market for networking solutions is characterized by rapidly changing technology, accelerating product introduction cycles, changes in customer requirements and evolving industry standards. Brocade’s future success depends largely upon its ability to address the rapidly changing needs of its customers by developing and supplying high-quality, cost-effective products, product enhancements and services on a timely basis and by keeping pace with technological developments and emerging industry standards. This risk will likely become more pronounced as the networking markets become more competitive and as demand for new and improved technologies increases.

Brocade has introduced a significant number of new products in the last 12 months, including products across its family of Ethernet and Data Storage networking solutions, which accounts for a substantial portion of Brocade’s revenues. Brocade has also invested significant R&D resources in developing new products based on Ethernet Fabric technology for server virtualization within data centers. Specifically, Brocade has recently

13

introduced the Brocade VDX Ethernet Fabric Switches powered by its Virtual Cluster Switching (“VCS”) technologies as the first products within this category.

Developing new offerings requires significant upfront investments that may not result in revenue for an extended period of time, if at all. Brocade must achieve widespread market acceptance of Brocade’s new product and service offerings on a timely basis in order to realize the benefits of Brocade’s investments. Additionally, Brocade recently focused substantial resources to emphasize the Ethernet networking market through a channels strategy, including the hiring of incremental new sales persons focused primarily on Brocade’s Ethernet networking products. This focus towards the Ethernet networking market may negatively impact Brocade’s other businesses such as its Data Storage networking products because management’s attention and limited resources such as employees may be reallocated away from Brocade’s Data Storage products and towards Ethernet products instead.

The success of Brocade’s product and service offerings depends on numerous factors, including its ability to:

• Properly determine the market for and define new products and services;

• Develop and introduce the new products and services in a timely manner;

• Differentiate Brocade’s new products and services from its competitors’ technology and product offerings;

• Address the complexities of interoperability of Brocade’s products with its installed base, OEM partners’ server and storage products and its competitors’ products; and

• Maintain high levels of product quality and reliability.

Various factors impacting market acceptance are outside of Brocade’s control, including the following:

• The availability and price of competing products and alternative technologies;

• The cost of certain product subcomponents, which could reduce Brocade’s gross margins;

• Product qualification requirements by Brocade’s OEM partners, which can cause delays in the market acceptance;

• The timing of the adoption of new industry standards relative to Brocade’s development of new technologies and products;

• The ability of its OEM partners to successfully distribute, support and provide training for its products; and

• Customer acceptance of Brocade’s products, including its Ethernet solutions.

If Brocade is not able to successfully develop and market new and enhanced products and services on a timely basis, its business and results of operations will likely be harmed.

As Brocade introduces new or enhanced products, Brocade must also successfully manage the transition from older products to minimize disruption in customers’ ordering patterns, avoid excessive levels of older product inventories and provide sufficient supplies of new products to meet customer demands. When Brocade introduces new or enhanced products, Brocade faces numerous risks relating to product transitions, including the inability to accurately forecast demand, manage excess and obsolete inventories, address new or higher product cost structures, and manage different sales and support requirements due to the type or complexity of the new products. In addition, any customer uncertainty regarding the timeline for rolling out new products or Brocade’s plans for future support of existing products may negatively impact customer purchase decisions.

14

The prices of Brocade’s products have declined in the past and Brocade expects the prices of Brocade’s products to continue to decline, which could reduce Brocade’s revenues, gross margins and profitability.

The average selling price for Brocade’s products has declined in the past, and Brocade expects it to continue to decline in the future as a result of changes in competitive pricing pressure, broader macroeconomic factors, product mix, increased sales discounts, new product introductions by Brocade or Brocade’s competitors, the entrance of new competitors and other factors. Brocade expects that average selling prices per port for Data Storage products will continue to decline at rates consistent with historical rates of low single digits per quarter, and that average selling prices per port for Brocade’s Ethernet products will decline in the low- to mid-single digits; however, average selling prices could decline much faster. Price declines may also increase as competitors ramp up product releases that compete with Brocade’s products. Furthermore, as a result of cautious capital spending in the technology sector, coupled with broader macroeconomic factors, both Brocade and its competitors may pursue more aggressive pricing strategies in an effort to maintain or seek to increase sales levels. If Brocade is unable to offset any negative impact that changes in competitive pricing pressures, broader macroeconomic factors, product mix, increased sales discounts, enhanced marketing programs, new product introductions by Brocade or Brocade’s competitors, or other factors may have on the average selling price of Brocade’s products by increasing the volume of products shipped or reducing product manufacturing costs, Brocade’s total revenues and gross margins will be negatively impacted.

In addition, to maintain Brocade’s gross margins, Brocade must maintain or increase the number of products shipped, develop and introduce new products and product enhancements, and continue to reduce the manufacturing costs of Brocade’s products. While Brocade has successfully reduced the cost of manufacturing Brocade’s products in the past, Brocade may not be able to continue to reduce cost of production at historical rates. Moreover, most of Brocade’s expenses are fixed in the short-term or incurred in advance of receipt of corresponding revenue. As a result, Brocade may not be able to decrease its spending quickly enough or in sufficient amounts to offset any unexpected shortfall in revenues. If this occurs, Brocade could incur losses and Brocade’s operating results and gross margins could be below expectations. Additionally, Brocade’s gross margins may be negatively affected by fluctuations in manufacturing volumes, component costs, foreign currency exchange rates, the mix of product configurations sold and the mix of distribution channels through which its products are sold. In addition, if product or related warranty costs associated with Brocade’s products are greater than previously experienced, Brocade’s gross margins may also be adversely affected. Finally, increased costs resulting from higher-than-anticipated oil prices and the volatility of the value of the U.S. dollar may affect the costs of components used in Brocade’s products and negatively affect Brocade’s gross margins.

The failure to accurately forecast demand for Brocade’s products or the failure to successfully manage the production of Brocade’s products could negatively affect the supply of key components for Brocade’s products and Brocade’s ability to manufacture and sell Brocade’s products.

Brocade provides product forecasts to its contract manufacturers and places purchase orders with them in advance of the scheduled delivery of products to Brocade’s customers. Moreover, in preparing sales and demand forecasts, Brocade relies largely on input from its partners and its resellers and end-user customers. Therefore, if Brocade or its partners are unable to accurately forecast demand, or if Brocade fails to effectively communicate with its distribution partners about end-user demand or other time-sensitive information, the sales and demand forecasts may not reflect the most accurate, up-to-date information. If these forecasts are inaccurate, Brocade may be unable to obtain adequate manufacturing capacity from its contract manufacturers to meet customers’ delivery requirements or Brocade may accumulate excess inventories. Furthermore, Brocade may not be able to identify forecast discrepancies until late in its fiscal quarter. Consequently, Brocade may not be able to make adjustments to its business model. If Brocade is unable to obtain adequate manufacturing capacity from its contract manufacturers, or if Brocade is unable to make necessary adjustments to Brocade’s business model, revenue may be delayed or even lost to Brocade’s competitors and Brocade’s business and financial results may be harmed. If excess inventories accumulate, Brocade’s gross margins may be negatively impacted by write- downs for excess and/or obsolete inventory. In addition, Brocade may experience higher fixed costs as it expands

15

its contract manufacturer capabilities, which could negatively affect Brocade’s ability to react quickly if demand suddenly decreases.

Brocade’s ability to accurately forecast demand also may become increasingly more difficult as Brocade enters new or adjacent markets, introduces new products, begins phasing out certain products, or acquires other companies or businesses. Forecasting demand for new or adjacent markets, particularly where the markets are not yet well-established, may be highly speculative and uncertain. For products that are nearing end of life or are being replaced by new versions, it may be difficult to forecast how quickly to decrease production on the older products and ramp up production on the new products. Brocade may be unable to obtain adequate supply of new product components and/or manufacturing capacity from its contract manufacturers to meet customers’ delivery requirements that may negatively impact revenues, or Brocade may accumulate excess inventories that may negatively impact gross margins due to write-downs for excess and/or obsolete inventory. In addition, acquired companies or businesses may offer less visibility into demand than Brocade typically has experienced, may cause customer uncertainty regarding purchasing decisions, and may use different measures to evaluate demand that are less familiar to Brocade and thus more difficult to accurately predict.

In addition, although the purchase orders placed with Brocade’s contract manufacturers are cancelable in certain circumstances, Brocade could be required to purchase certain unused material not returnable, usable by, or sold to other customers if Brocade cancels any of Brocade’s orders. This purchase commitment exposure is particularly high in periods of new product introductions and product transitions. If Brocade is required to purchase unused material from Brocade’s contract manufacturers, Brocade could incur unanticipated expenses, including write-downs for excess and/or obsolete inventory, and Brocade’s business and financial results could be negatively affected. In the past, Brocade has experienced delays in shipments of its Ethernet products from its contract manufacturers and OEMs, which in turn delayed product shipments to its customers. Brocade may in the future experience similar delays or other problems, such as insufficient quantity of product, acquisition by a competitor or business failure of any of its OEMs, any of which could harm Brocade’s business and operating results.

Brocade is subject to, and may in the future be subject to other, intellectual property infringement claims and litigation that are costly to defend and/or settle, and that could result in significant damage and cost awards against Brocade and limit Brocade’s ability to use certain technologies in the future.

Brocade competes in markets that are frequently subject to claims and related litigation regarding patent and other intellectual property rights. From time to time, third parties have asserted patent, copyright, trade secret, and/or other IP-related claims against Brocade and/or employees of Brocade. These claims may be, and have been in the past, made against Brocade’s products and services, subcomponents of its products, methods performed by its products or used in its operations, or uses of its products by its customers, or may concern Brocade’s hiring of a former employee of the third party claimant. Brocade and companies acquired by Brocade, such as Foundry, have in the past incurred, are currently incurring and will in the future incur substantial expenses to defend against such third-party claims. For instance, Brocade currently is defending patent-related lawsuits, including lawsuits originally filed against Foundry by Enterasys Networks, Inc. and Chrimar Systems, Inc. In addition, Brocade may be subject to indemnification obligations with respect to infringement of third-party intellectual property rights pursuant to Brocade agreements with suppliers, OEM and channel partners or customers. The opposing litigants and other third party asserters of such intellectual property claims may be unreasonable in their positions, or in their demands, or may simply refuse to settle, which could lead to expensive settlement payments, prolonged periods of litigation expenses, additional burden on employees or other resources and distraction from Brocade’s business initiatives and operations. In the event of an adverse determination, Brocade could incur substantial monetary liability and be prohibited from utilizing certain technology, hiring certain people, shipping or importing certain products or incorporating necessary components into Brocade’s products. Suppliers of components or OEM systems to Brocade may be unwilling to, or not be able to, defend or indemnify Brocade against third-party assertions directed at the components or systems they supply to Brocade, and may be unwilling to take licenses that would assure Brocade’s supply of such components or OEM systems.

16

Customers may perceive such third-party intellectual property claims as risks, and may, as a result, be less willing to do business with Brocade. Such litigation could also negatively impact Brocade’s recruiting efforts or ability to retain its employees. Any of the above scenarios could have a material adverse effect on Brocade’s financial position, results of operations, cash flows, and future business prospects.

Brocade’s intellectual property rights may be infringed or misappropriated by others, and Brocade may not be able to protect or enforce its intellectual property rights.

Brocade’s intellectual property rights may be infringed or misappropriated by others. In some cases, such infringement or misappropriation may be undetectable, or enforcement of Brocade’s rights may be impractical. Brocade has filed, and may in the future file, lawsuits against third parties in an effort to enforce its intellectual property rights. For instance, Brocade filed in the fourth quarter of fiscal year 2010 a patent infringement, copyright infringement, trade secret misappropriation and unfair competition lawsuit against A10 Networks, Inc. and certain individuals. Intellectual property litigation is expensive and unpredictable. There can be no assurance that Brocade will prevail in such enforcement efforts, either on the merits, or with respect to particular relief sought, such as damages or an injunction. Further, the opposing party may attempt to prove that the asserted intellectual property rights are invalid or unenforceable, and, if successful, may seek recompense for its attorney fees and costs. Further, the opposing party may counterclaim against Brocade, for example, for infringement of its own patents or intellectual property rights, or other intellectual property, tort or contract claims, which could lead to further expense and potential exposure for Brocade.

Brocade relies on a combination of patent, copyright, trademark and trade secret laws, physical and operational security and contractual restrictions on disclosure, to protect its intellectual property rights in its proprietary technologies, but none of these methods of protection may be entirely reliable, due to, for instance, employee hiring and turnover, geographic dispersion of employees, technology disclosures with suppliers, customers, and partners, unpredictable events, misappropriation or negligence, operations in various countries that do not have well-established or reliable enforcement institutions or customs, and other aspects of doing business on the scale of Brocade’s operations. Brocade attempts to identify its technological developments for assessment of whether to file patent applications, but there can be no assurance that all patentable technological developments will be captured in patent applications. Further, although Brocade has patent applications pending, there can be no assurance that patents will be issued from pending applications, or that claims allowed on any future patents will be sufficiently broad to protect its technology. Further, physical and operational security can be adversely affected by employee carelessness or disregard for policies, malfeasors, or changes in technology, such as the now-near-ubiquitous availability of portable memory devices. The value, validity, and enforceability of intellectual property rights generated by Brocade’s operations, obtained from acquired companies, or purchased from third parties, are subject to many unknowns, and may not ultimately have the value originally anticipated. In addition, due to less developed intellectual property regimes in certain jurisdictions, Brocade may not be able to protect fully its intellectual property as Brocade expands its operations globally.

Brocade uses several different routes to market for executing on its sales strategy including use of an OEM sales model focused on a few major OEM partners, and an expanded channel sales model. The loss of any of these OEM customers or channel partners or any other significant failure to execute on Brocade’s overall sales strategy could significantly reduce Brocade’s revenues and negatively affect Brocade’s financial results.

Brocade recently began to offer its products through new and expanded channels, including through OEMs, resellers, distributors and direct. For example, Brocade recently announced that EMC, in addition to previous announcements with IBM and Dell, would sell Brocade’s Ethernet networking products. However, these new and expanded channels may not generate much, if any, revenue opportunities for Brocade. Offerings through new channels may also require Brocade to make certain significant upfront or ongoing investments. These additional costs may not be recovered or may not provide the desired return on investment if the anticipated benefits are not ultimately successful. These costs may also be larger than anticipated if the expenses associated with this new

17

channels strategy are greater than planned. If Brocade cannot successfully expand its sales channels, Brocade may fail to maintain or grow its business, which would negatively impact its financial results.

Brocade depends on recurring purchases from a limited number of large OEM partners for a substantial portion of its revenues. As a result, these large OEM partners have a significant influence on Brocade’s quarterly and annual financial results. For fiscal years 2010, 2009 and 2008, the same three customers each represented 10% or more of Brocade’s total net revenues. Brocade’s agreements with its OEM partners are typically cancelable, non-exclusive, have no minimum purchase requirements and have no specific timing requirements for purchases. Brocade’s OEM partners could also elect to eliminate, reduce, or rebalance, the amount they purchase from Brocade and/or increase the amount purchased from Brocade’s competitors. Also, one or more of Brocade’s OEM partners could elect to consolidate or enter into a strategic partnership with one of Brocade’s competitors, which could reduce or eliminate Brocade’s future revenue opportunities with that OEM partner. Brocade anticipates that a significant portion of its revenues and operating results will continue to depend on sales to a relatively small number of OEM partners. The loss of any one significant OEM partner, or a decrease in the level of sales to any one significant OEM partner, or unsuccessful quarterly negotiation on key terms, conditions or timing of purchase orders placed during a quarter, would likely cause serious harm to Brocade’s business and financial results.

Brocade’s OEM partners evaluate and qualify Brocade’s products for a limited time period before they begin to market and sell them. Assisting Brocade’s OEM partners through the evaluation process requires significant sales, marketing and engineering management efforts on Brocade’s part, particularly if Brocade’s products are being qualified with multiple distribution partners at the same time. In addition, once Brocade’s products have been qualified, its customer agreements have no minimum purchase commitments. Brocade may not be able to effectively maintain or expand its distribution channels, manage distribution relationships successfully, or market its products through distribution partners. Brocade must continually assess, anticipate and respond to the needs of its distribution partners and their customers, and ensure that its products integrate with their solutions. Brocade’s failure to successfully manage its distribution relationships or the failure of its distribution partners to sell Brocade’s products could reduce Brocade’s revenues significantly. In addition, Brocade’s ability to respond to the needs of its distribution partners in the future may depend on third parties producing complementary products and applications for Brocade’s products. If Brocade fails to respond successfully to the needs of these groups, its business and financial results could be harmed.

The loss or delay of continued orders from any of Brocade’s more significant customers, such as the U.S. government or individual agencies within the U.S. government, or companies within the financial services, education and health sectors, could also cause its revenue and profitability to suffer. For example, if Brocade is unable to offer qualified products to such government customers due to regulations and requirements with respect to country of origin designation, or if Brocade experiences governmental procurement delays due to the timing of approval of the federal budget or other reasons. Brocade’s government orders could decrease, which would negatively impact its revenue and operating results. In addition, Brocade’s ability to attract new customers will depend on a variety of factors, including the cost-effectiveness, reliability, scalability, breadth and depth of its products. In addition, a change in the mix of Brocade’s customers, or a change in the mix of direct and indirect sales, could adversely affect its revenue and gross margins.

Brocade is dependent on sole source and limited source suppliers for certain key components, the loss of which may significantly impact results of operations.

Although Brocade uses standard parts and components for its products where possible, Brocade’s contract manufacturers currently purchase, on Brocade’s behalf, several key components used in the manufacture of its products from single or limited supplier sources. Brocade’s principal single source components include its application-specific integrated circuits (“ASICs”) and Brocade’s principal limited source components include memory, certain oscillators, microprocessors, certain connectors, certain logic chips, power supplies, programmable logic devices, printed circuit boards, certain optical components, packet processors and switching

18

fabrics. Brocade generally acquires these components through purchase orders and has no long-term commitments regarding supply or pricing with such suppliers. If Brocade is unable to obtain these and other components when required or if Brocade experiences significant component defects, Brocade may not be able to deliver Brocade’s products to Brocade’s customers in a timely manner. In addition, a challenging economic or industry environment could cause some of these sole source or limited source suppliers to delay or halt production or to go out of business or be acquired by third parties, which could result in a disruption in Brocade’s supply chain. Brocade’s supply chain could also be disrupted in a variety of other circumstances that may impact its suppliers and partners, including adverse results from intellectual property litigation or natural disasters. As a result, Brocade’s business and financial results could be harmed.

In addition, the loss of any of Brocade’s major third-party contract manufacturers could significantly impact Brocade’s ability to produce its products for an indefinite period of time. Qualifying a new contract manufacturer and commencing volume production is typically a lengthy and expensive process. If Brocade is required to change any of its contract manufacturers or if any of its contract manufacturer experiences delays, disruptions, capacity constraints, component parts shortages or quality control problems in its manufacturing operations, shipment of Brocade’s products to Brocade’s customers could be delayed and result in loss of revenues and Brocade’s competitive position and relationship with customers could be harmed.

Changes in industry structure and market conditions could lead to charges related to discontinuances of certain of Brocade’s products or businesses and asset impairments.

Brocade carries a substantial amount of acquired intangible assets, goodwill and deferred tax assets on its balance sheet. The goodwill and acquired intangibles predominately relate to the Ethernet business in connection with Brocade’s acquisition of Foundry in December 2008. Brocade’s determination of fair value of long-lived assets relies on management’s assumptions of future revenues, operating costs, and other relevant factors. In response to changes in industry and market conditions, Brocade may be required to realign its resources strategically and consider restructuring, disposing of, or otherwise exiting businesses. Any decision to limit investment in, or dispose of or otherwise exit businesses may result in the recording of special charges, such as inventory and technology-related write-offs, workforce reduction costs, charges relating to consolidation of excess facilities, or claims from third parties who were resellers or users of discontinued products. Similarly, if management’s estimates of future operating results change or if there are changes to other assumptions, such as the discount rate applied to future cash flows, the estimate of the fair value of Brocade’s reporting units could change significantly, which could result in goodwill impairment charges. Brocade’s estimates with respect to the useful life or ultimate recoverability of Brocade’s carrying basis of assets, including purchased intangible assets, could change as a result of such assessments and decisions. For example, during the three months ended May 2, 2009, Brocade recorded a non-cash $53.3 million impairment charge in connection with the decision to no longer offer Brocade’s suite of Files products. Brocade is required to perform goodwill impairment tests on an annual basis and between annual tests in certain circumstances, and future goodwill impairment tests may result in a charge to earnings (see Note 4, “Goodwill and Intangible Assets,” of the Notes to Condensed Consolidated Financial Statements, and sensitivity analysis performed in Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations).

Brocade concludes that it is more-likely-than-not that the Company will realize its deferred tax assets based on positive evidence of its history of profits and projections of future income. Accordingly, the Company only applies a valuation allowance on the deferred tax assets relating to capital loss and investment loss carryforwards. In the event future income by jurisdiction is less than what is currently projected, Brocade may be required to apply a valuation allowance to these deferred tax assets in jurisdictions where realization of such assets are no longer more-likely-than-not (see Note 15, “Income Taxes”, of the Notes to Consolidated Financial Statements).

Brocade’s estimates relating to the liabilities for excess facilities are also affected by changes in real estate market conditions. In addition, Brocade has made investments in certain private companies which could become impaired if the operating results of those companies change adversely.

19

Brocade may not realize the anticipated benefits of past or future acquisitions and strategic investments, and integration of acquired companies or technologies may negatively impact Brocade’s business.

Brocade has in the past acquired, or made strategic investments in, other companies, products or technologies, and Brocade expects to make additional acquisitions and strategic investments in the future. Examples of recent acquisitions include Foundry in December 2008, Strategic Business Systems, Inc. in March 2008 and McDATA Corporation in January 2007. Brocade may not realize the anticipated benefits of any of its acquisitions or strategic investments, which involve numerous risks, including:

• Difficulties in successfully integrating the acquired businesses;

• Inability to effectively coordinate sales and marketing efforts to communicate the capabilities of the combined company;

• Revenue attrition in excess of anticipated levels if existing customers alter or reduce their historical buying patterns;

• Unanticipated costs, litigation and other contingent liabilities;

• Diversion of management’s attention from Brocade’s daily operations and business;

• Adverse effects on existing business relationships with suppliers and customers;

• Risks associated with entering into markets in which Brocade has limited or no prior experience;

• Inability to attract and retain key employees;

• Inability to retain key customers, distributors, vendors and other business partners of the acquired business;

• Inability to successfully develop new products and services on a timely basis that address the market opportunities of the combined company;

• Inability to compete effectively against companies already serving the broader market opportunities expected to be available to the combined company;

• Inability to qualify the combined company’s products with OEM partners on a timely basis, or at all;

• Failure to consolidate the combined company’s professional services and customer support organizations;

• Inability to successfully integrate and harmonize financial reporting and information technology systems;

• Failure to successfully manage additional remote locations, including the additional infrastructure and resources necessary to support and integrate such locations;

• Assumption or incurrence of debt and contingent liabilities and related obligations to service such liabilities and Brocade’s ability to satisfy financial and other negative operating covenants;

• Additional costs such as increased costs of manufacturing and service costs, costs associated with excess or obsolete inventory, costs of employee redeployment, relocation and retention, including salary increases or bonuses, accelerated amortization of deferred equity compensation and severance payments, reorganization or closure of facilities, taxes, advisor and professional fees, and termination of contracts that provide redundant or conflicting services;

• Incurrence of significant exit charges if products acquired in business combinations are unsuccessful;

• Incurrence of acquisition and integration related costs, accounting charges, or amortization costs for acquired intangible assets, that could negatively impact Brocade’s operating results and financial condition;

20

• Potential write-down of goodwill, acquired intangible assets and/or deferred tax assets, which are subject to impairment testing on an annual basis, and could significantly impact Brocade’s operating results; and

• Dilution of the ownership percentage held by Brocade’s stockholders to the extent equity is used as consideration or option plans are assumed, such as in the case of the Foundry acquisition, in which approximately 125.1 million additional shares of Brocade common stock became issuable in connection with the assumption or substitution of Foundry equity awards.

If Brocade is not able to successfully integrate businesses, products, technologies or personnel that Brocade acquires, or to realize expected benefits of Brocade’s acquisitions or strategic investments, Brocade’s business and financial results would be adversely affected.

Brocade’s quarterly and annual revenues and operating results may fluctuate in future periods due to a number of factors, which make predicting results of operations difficult and could adversely affect the trading price of Brocade’s stock.

Information technology spending is subject to cyclical and uneven fluctuations. It can be difficult to predict the degree to which the seasonality and uneven sales patterns of Brocade’s OEM partners or other customers will affect Brocade’s business in the future, particularly as Brocade releases new products. While Brocade’s first and fourth fiscal quarters have typically been seasonally stronger quarters than its second and third fiscal quarters, particularly for storage networking products, future buying patterns may differ from historical seasonality. In addition, the Federal budget for government IT spending can be subject to delay and uncertainty from time to time due to political and legislative volatility, which can cause Brocade’s financial results to fluctuate unevenly and unpredictably.

Uneven sales patterns are not only difficult to predict, but also can result in irregular shipment patterns that can cause shortages or underutilized capacity, increase costs due to higher inventory levels, and otherwise adversely impact inventory planning. For example, Brocade’s Ethernet networking business has experienced significantly higher levels of sales towards the end of a period. Orders received towards the end of the period may not ship within the period due to Brocade’s manufacturing lead times. This exposes Brocade to additional inventory risk because Brocade must order products in anticipation of expected future orders and additional sales risk if Brocade is unable to fulfill unanticipated demand. In addition, receipt of a high number of customer orders towards the end of a fiscal quarter will increase reported receivables outstanding as a fraction of reported sales and result in higher days sales outstanding.

Brocade’s quarterly and annual revenues and operating results may vary significantly in the future due to the factors noted above as well as other factors, including but not limited to, the following:

• Disruptions, or a continued decline, in general economic conditions, particularly in the information technology industry;

• Announcements of pending or completed acquisitions or other strategic transactions by Brocade, its competitors or its partners;

• Announcements, introductions and transitions of new products by Brocade, its competitors or its partners;

• The timing of customer orders, product qualifications and product introductions of Brocade’s partners;

• Long and complex sales cycles;

• Internal supply and inventory management objectives of Brocade’s OEM partners and other customers;

• Brocade’s ability to timely produce products that comply with new environmental restrictions or related requirements of its customers;

21

• Brocade’s ability to obtain sufficient supplies of sole- or limited-sourced components, including ASICs, microprocessors, certain connectors, certain logic chips and programmable logic devices;

• Increases in prices of components used in the manufacture of Brocade’s products;

• Variations in the mix of Brocade’s products sold and the mix of distribution channels and geographies through which they are sold;

• Pending or threatened litigation, including any settlements or judgments related to such litigation;

• Stock-based compensation expense that is affected by Brocade’s stock price;

• Examinations by government tax authorities that may have unfavorable outcomes and subject Brocade to additional tax liabilities;

• New legislation and regulatory developments, including increases to tax rates or changes to treatment of an income or expense item; and

• Other risk factors detailed in this section.

Accordingly, Brocade’s quarterly and annual revenues and operating results may vary significantly in future. The results of any prior periods should not be relied upon as an indication of future performance. Brocade cannot assure you that in some future quarter Brocade’s revenues or operating results will not be below Brocade’s projections or the expectations of stock market analysts or investors, which could cause Brocade’s stock price to decline.

The recent economic slowdown adversely affected Brocade’s operating results and financial condition and economic slowdowns in the future may have similar or greater negative impact.

In the past, unfavorable or uncertain economic conditions and reduced global information technology spending rates have resulted in growth rates below historical patterns and have adversely affected Brocade’s operating results. For example, the domestic and global economies recently underwent a period of significant uncertainty and slowdown, which resulted in reduced demand for information technology, including high-performance data networking solutions. In addition, the domestic and global economies could experience a prolonged slowdown or even a “double dip” recession that could further reduce demand for information technology products. Brocade is particularly susceptible to reductions in information technology spending because the purchase of IT-related products is often discretionary and may involve a significant commitment of capital and other resources. Different geographic regions (e.g., EMEA or Japan) may experience greater economic slowdowns and/or longer recovery periods, which may adversely impact IT spending in those regions. Future delays or reductions in information technology spending, domestically and/or internationally, could harm Brocade’s business, results of operations and financial condition in a number of ways, including longer sales cycles, increased inventory provisions, increased production costs, lowered prices for its products and reduced sales volumes. Similarly, if Brocade’s suppliers face challenges in obtaining credit or otherwise in operating their businesses, they may become unable to continue to offer the materials Brocade uses to manufacture its products or may offer the materials at higher prices. These events have caused, and future slowdowns may cause, reductions in Brocade’s revenue, profitability and cash flows; increased price competition and operating costs; longer fulfillment cycles; and may cause many other risks noted in this filing, which could adversely affect Brocade’s business, results of operations and financial condition.

Economic slowdowns can also make it difficult for Brocade, its customers and its suppliers to accurately forecast future product demand. This reduced visibility could cause Brocade to produce excess products that would increase its inventory carrying costs and result in obsolete inventory. Alternatively, this forecasting difficulty could cause a shortage of products or materials used in Brocade’s products that would result in its inability to satisfy demand for its products and a loss of market share.

22

Brocade has extensive international operations, which subjects it to additional business risks.

A significant portion of Brocade’s sales occur in international jurisdictions. In addition, Brocade’s contract manufacturers have significant operations in China. Brocade plans to continue to expand its international operations and sales activities. Brocade’s international sales of its Ethernet networking products have primarily depended on its resellers, including Pan Dacom GmbH in Europe, Stark Technology Inc. in Taiwan, Net One Systems in Japan and Samsung Corporation in Korea. The failure by international resellers to sell Brocade’s products could limit its ability to sustain and grow revenue. Maintenance or expansion of international operations involves inherent risks that Brocade may not be able to control, including:

• Exposure to economic instability or fluctuations in international markets;

• Reduced or limited protection of intellectual property rights, particularly in jurisdictions that have less developed intellectual property regimes such as China and India;

• Managing research and development teams in geographically diverse locations, including teams divided between the United States and India;

• Significant wage inflation in certain growing economies such as India;

• Increased exposure to foreign currency exchange rate fluctuations, including the appreciation of foreign currencies such as the Chinese yuan;

• Supporting multiple languages;

• Recruiting sales and technical support personnel with the skills to design, manufacture, sell and support Brocade’s products;

• Complying with governmental regulation of encryption technology and regulation of imports and exports, including obtaining required import or export approval for its products;

• Increased complexity and costs of managing international operations;

• Commercial laws and business practices that favor local competition;

• Multiple, potentially conflicting, and changing governmental laws, regulations and practices, including differing export, import, tax, labor, anti-bribery and employment laws;

• Longer sales cycles and manufacturing lead times;

• Increased costs of local labor, including labor markets in China and India;

• Difficulties in collecting accounts receivable; and

• Increased complexity of logistics and distribution arrangements.

Failure to manage expansion effectively could seriously harm Brocade’s business, financial condition and prospects. In addition, international political instability may halt or hinder Brocade’s ability to do business and may increase Brocade’s costs. Various events, including the occurrence or threat of terrorist attacks, increased national security measures in the United States and other countries, and military action and armed conflicts, may suddenly increase international tensions. Such events may have an adverse effect on the world economy and could adversely affect Brocade’s business operations or the operations of Brocade’s OEM partners, contract manufacturers and suppliers.

To date, no material amount of Brocade’s international revenues and cost of revenues have been denominated in foreign currencies. As a result, an increase in the value of the U.S. dollar relative to foreign currencies could make Brocade’s products more expensive and, thus, not competitively priced in foreign markets. Additionally, a decrease in the value of the U.S. dollar relative to foreign currencies could increase Brocade’s product and operating costs in foreign locations (e.g., appreciation of the Chinese yuan). In the future, a larger portion of Brocade’s international revenues may be denominated in foreign currencies, which will

23

subject Brocade to additional risks associated with fluctuations in those foreign currencies. In addition, Brocade may be unable to successfully hedge against any such fluctuations.

Business interruptions could adversely affect Brocade’s business.

Brocade’s operations and the operations of its suppliers, contract manufacturers and customers are vulnerable to interruptions by fire, earthquake, hurricane, power loss, telecommunications failure and other events beyond Brocade’s control. For example, a substantial portion of Brocade’s facilities, including its corporate headquarters, is located near major earthquake faults. Brocade does not have multiple site capacity for all of its services in the event of any such occurrence. In the event of a major earthquake, Brocade could experience business interruption, destruction of facilities and loss of life. Brocade carries a limited amount of earthquake insurance, which may not be sufficient to cover earthquake-related losses, and has not set aside funds or reserves to cover other potential earthquake-related losses. Additionally, major public health issues such as an outbreak of a pandemic or epidemic may interrupt business operations in those geographic regions affected by that particular health issue. In addition, one of Brocade’s contract manufacturers has a major facility located in an area that is subject to hurricanes. In the event that a material business interruption occurs that affects Brocade, its suppliers, contract manufacturers or customers, shipments could be delayed and Brocade’s business and financial results could be harmed. Despite Brocade’s implementation of network security measures, its servers may be vulnerable to computer viruses, break-ins, and similar disruptions from unauthorized tampering with its computer systems. Brocade may not carry sufficient insurance to compensate for losses that may occur as a result of any of these events.

Undetected software or hardware errors could increase Brocade’s costs, reduce Brocade’s revenues and delay market acceptance of Brocade’s products.

Networking products frequently contain undetected software or hardware errors, or bugs, when first introduced or as new versions are released. Brocade’s products are becoming increasingly complex and particularly, as Brocade continues to expand its product portfolio to include software-centric products, including software licensed from third parties, errors may be found from time to time in Brocade’s products. In addition, through its acquisitions, Brocade has assumed, and may in the future assume, products previously developed by an acquired company that have not been through the same level of product development, testing and quality control processes used by Brocade, and may have known or undetected errors. Some types of errors also may not be detected until the product is installed in a heavy production or user environment. In addition, Brocade’s products are often combined with other products, including software, from other vendors, and these products often need to interface with existing networks, each of which have different specifications and utilize multiple protocol standards and products from other vendors. As a result, when problems occur, it may be difficult to identify the source of the problem. These problems may cause Brocade to incur significant warranty and repair costs, may divert the attention of engineering personnel from product development efforts, and may cause significant customer relations problems. Moreover, the occurrence of hardware and software errors, whether caused by another vendor’s storage, data management or Ethernet products or Brocade’s, could delay market acceptance of Brocade’s new products.

If Brocade loses key talent or is unable to hire additional qualified talent, Brocade’s business may be harmed.

Brocade’s success depends, to a significant degree, upon the continued contributions of key management, engineering, sales and other talent, many of whom would be difficult to replace. Brocade believes its future success will also depend, in large part, upon Brocade’s ability to attract and retain highly skilled managerial, engineering, sales and other talent, and on the ability of management to operate effectively, both individually and as a group, in geographically diverse locations. There is a limited number of qualified talent in each applicable market and competition for such employees is strong. In particular, Brocade operates in various locations with competitive labor markets including Bangalore, India and San Jose, California, as well as certain emerging labor

24

markets, such as the Eastern European and Latin American markets. In the past, Brocade has experienced difficulty in hiring qualified talent in areas such as ASICs, software, system and test, sales, marketing, service, key management and customer support. Any future declines in Brocade’s stock price will reduce the value of equity awards and may result in additional “underwater” stock options held by its employees. If such a decline in Brocade’s stock price were to occur, Brocade’s ability to incentivize or retain qualified talent could be negatively impacted. Brocade’s ability to retain qualified talent may also be affected by future and recent acquisitions, which may cause uncertainty and loss of key talent. The loss of the services of any of Brocade’s key employees, the inability to attract or retain qualified talent in the future, or delays in hiring required talent, particularly engineers and sales talent, could delay the development and introduction of Brocade’s products or services, and negatively affect Brocade’s ability to sell its products or services.

In addition, companies in the computer storage, networking and server industries whose employees accept positions with competitors may claim that their competitors have engaged in unfair hiring practices or that there will be inappropriate disclosure of confidential or proprietary information. Brocade may be subject to such claims in the future as Brocade seeks to hire additional qualified talent. Such claims could result in litigation. As a result, Brocade could incur substantial costs in defending against these claims, regardless of their merits, and be subject to additional restrictions if any such litigation is resolved against Brocade.

Brocade incurred substantial indebtedness to finance the acquisition of Foundry that decreases Brocade’s business flexibility and access to capital, and increases its borrowing costs, which may adversely affect Brocade’s operations and financial results.

Upon completion of the acquisition of Foundry in December 2008, Brocade increased its indebtedness by approximately $1.1 billion, which is substantially greater than its indebtedness prior to the acquisition. The $1.1 billion debt was originally issued under a term loan facility. While the amount of the debt has been refinanced and reduced in part, the financial and other covenants agreed to by Brocade in connection with such indebtedness and the increased indebtedness and higher debt-to-equity ratio of Brocade in comparison to that of Brocade on a recent historical basis will have the effect, among other things, of reducing Brocade’s flexibility to respond to changing business and economic conditions and increasing borrowing costs, and may adversely affect Brocade’s operations and financial results. The increased indebtedness may also adversely affect Brocade’s ability to access sources of capital or incur certain liens. In addition, Brocade’s failure to comply with these covenants could result in a default under the applicable debt financing agreements, which could permit the holders to accelerate such debt or demand payment in exchange for a waiver of such default. If any of Brocade’s debt is accelerated, Brocade may not have sufficient funds available to repay such debt. The current debt under the Senior Secured Credit Facility has a floating interest rate and an increase in interest rates may negatively impact Brocade’s financial results. The mandatory debt repayment schedule on the Senior Secured Credit Facility may negatively impact Brocade’s cash position and reduce Brocade’s financial flexibility. In addition, any negative changes by rating agencies to Brocade’s credit rating may negatively impact the value and liquidity of Brocade’s debt and equity securities and Brocade’s ability to access sources of capital.

Brocade’s business is subject to increasingly complex corporate governance, public disclosure, accounting and tax requirements, and environmental regulations that could adversely affect Brocade’s business and financial results.

Brocade is subject to changing rules and regulations of federal and state government as well as the stock exchange on which Brocade’s common stock is listed. These entities, including the Public Company Accounting Oversight Board, the FASB, the SEC, the IRS and NASDAQ, have issued a significant number of new and increasingly complex requirements and regulations over the course of the last several years and continue to develop additional regulations and requirements in response to laws enacted by Congress. In addition, the Department of Treasury, the SEC and various Congressional representatives have recently proposed additional rules and regulations that may go into effect in the near future. On July 21, 2010, the Dodd-Frank Wall Street Reform and Protection Act was enacted. The Act included significant corporate governance and executive

25

compensation-related provisions and also required the SEC to adopt additional rules and regulations in areas such as “say on pay” and proxy access. Brocade is also subject to various rules and regulations of certain foreign jurisdictions, including applicable tax regulations. Brocade’s efforts to comply with these requirements have resulted in, and are likely to continue to result in, an increase in expenses and a diversion of management’s time from other business activities. Similarly, any change in the tax law in the jurisdictions in which Brocade does business, including an increase in tax rates or an adverse change in the treatment of an item of income or expense, could result in a material increase in Brocade’s tax expense. For example, in both the 2010 and 2011 budget proposals, the President of the United States and the U.S. Treasury Department proposed changing certain of the U.S. tax rules for U.S. corporations doing business outside the United States. In August 2010, the President enacted into law certain legislation impacting the use of foreign tax credits prospectively. Brocade is evaluating the provisions, but does not expect them to have a material impact to its financial results. Other legislation has not yet been proposed or enacted, but it is possible that these or other changes in the U.S. tax laws could increase Brocade’s U.S. income tax liability in the future.

Brocade is subject to periodic audits or other reviews by such governmental agencies. For example, Brocade is under examination by the IRS for its domestic federal income tax return for the fiscal years 2004 through 2008. In addition, Foundry’s California income tax returns for calendar years 2006 and 2007 are currently being examined by the California Franchise Tax Board. All these examination cycles remain open as of October 30, 2010. Brocade resolved its California income tax audit for the years ended October 25, 2003 and October 30, 2004. To the extent carryforwards from these years are used in the future, the California Franchise Tax Board has the right to audit the carryforward amounts. The SEC also periodically reviews Brocade’s public company filings. Any such examination or review frequently requires management’s time and diversion of internal resources and, in the event of an unfavorable outcome, may result in additional liabilities or adjustments to Brocade’s historical financial results.

The IRS is contesting Brocade’s transfer pricing for the cost sharing and buy-in arrangements with its foreign subsidiaries. Brocade appealed the Revenue Agent’s Report to the Appeals Office of the IRS for the years under examination through 2006. The IRS is also examining Brocade’s fiscal year 2007 and 2008 income tax returns. The IRS may make similar claims against Brocade’s transfer pricing arrangements in future examinations. Audits by the IRS are subject to inherent uncertainties and an unfavorable outcome could occur, such as fines or penalties. The occurrence of an unfavorable outcome in any specific period could have a material adverse effect on Brocade’s results of operations for that period or future periods. The expense of defending and resolving such an audit may be significant. The amount of time to resolve an audit is unpredictable and defending Brocade may divert management’s attention from Brocade’s day-to-day business operations, which could adversely affect Brocade’s business.

Brocade is subject to various environmental and other regulations governing product safety, materials usage, packaging and other environmental impacts in the various countries where Brocade’s products are sold. For example, many of Brocade’s products are subject to laws and regulations that restrict the use of lead, mercury, hexavalent chromium, cadmium and other substances, and require producers of electrical and electronic equipment to assume responsibility for collecting, treating, recycling and disposing of Brocade’s products when they have reached the end of their useful life. For example, in Europe, substance restrictions apply to products sold, and certain of Brocade’s partners require compliance with these or more stringent requirements. In addition, recycling, labeling, financing and related requirements apply to products Brocade sells in Europe. China has also enacted similar legislation with similar requirements for Brocade’s products or its partners. Despite Brocade’s efforts to ensure that its products comply with new and emerging requirements, Brocade cannot provide absolute assurance that its products will, in all cases, comply with such requirements. If Brocade’s products do not comply with the substance restrictions under local environmental laws, Brocade could become subject to fines, civil or criminal sanctions and contract damage claims. In addition, Brocade could be prohibited from shipping non-compliant products into one or more jurisdictions and required to recall and replace any non-compliant products already shipped, which would disrupt its ability to ship products and result in reduced revenue, increased obsolete or excess inventories, and harm to Brocade’s business and customer relationships. Brocade’s

26

suppliers may also fail to provide it with compliant materials, parts and components despite Brocade’s requirement to do so, which could impact Brocade’s ability to timely produce compliant products and, accordingly, could disrupt its business.

Brocade relies on licenses from third parties and the loss or inability to obtain any such license could harm its business.

Many of Brocade’s products are designed to include software or other intellectual property licensed from third parties. While it may be necessary in the future to seek or renew licenses relating to various aspects of its products, Brocade believes that, based upon past experience and standard industry practice, such licenses generally can be obtained on commercially reasonable terms. Nonetheless, there can be no assurance that the necessary licenses will be available on acceptable terms, if at all. Brocade’s inability to obtain certain licenses or other rights on favorable terms could have an adverse effect on Brocade’s business (including its ability to continue to distribute or support effected products), operating results and financial condition. In addition, if Brocade fails to carefully manage the use of “open source” software in Brocade’s products, Brocade may be required to license key portions of Brocade’s products on a royalty-free basis or expose key parts of source code.

Brocade is exposed to various risks related to legal proceedings or claims that could adversely affect its operating results.

Brocade is a party to lawsuits in the normal course of its business. Litigation in general can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to predict. Responding to lawsuits brought against Brocade, or legal actions initiated by Brocade, can often be expensive and time-consuming. Unfavorable outcomes from these claims and/or lawsuits could adversely affect Brocade’s business, results of operations, or financial condition, and Brocade could incur substantial monetary liability and/or be required to change its business practices.

Provisions in Brocade’s charter documents, customer agreements and Delaware law could prevent or delay a change in control of Brocade, which could hinder stockholders’ ability to receive a premium for Brocade’s stock.

Provisions of Brocade’s certificate of incorporation and bylaws may discourage, delay or prevent a merger or mergers that a stockholder may consider favorable. These provisions include:

• Authorizing the issuance of preferred stock without stockholder approval;

• Prohibiting cumulative voting in the election of directors;

• Limiting the persons who may call special meetings of stockholders; and

• Prohibiting stockholder actions by written consent.

Certain provisions of Delaware law also may discourage, delay or prevent someone from acquiring or merging with Brocade, and Brocade’s agreements with certain of Brocade’s customers require that Brocade give prior notice of a change of control and grant certain manufacturing rights following a change of control. Brocade’s various change-of-control provisions could prevent or delay a change in control of Brocade, which could hinder stockholders’ ability to receive a premium for Brocade’s stock.

Item 2. Properties

Brocade’s principal administrative, sales, marketing, education, customer support, and research and development facilities are located in approximately 667,000 square feet in San Jose, California. Additional administrative and research and development facilities are located in approximately 213,000 square feet, in aggregate, in Broomfield, Colorado and Plymouth, Minnesota. Approximately 150,000 square feet of such space is leased and 730,000 square feet is owned. Brocade believes that its existing properties, including both owned and leased, are in good condition and are suitable for the conduct of its business. Brocade also productively utilizes the majority of the space in its facilities.

Brocade’s leased properties have expirations through November 2020. In addition to the noted facilities, Brocade leases administrative, sales and marketing office space in various locations to serve its customers throughout the world. On May 23, 2008, the Company purchased property located in San Jose, California, which consisted of three unimproved building parcels that were entitled for approximately 562,000 square feet of space in three buildings. In connection with the purchase, Brocade also engaged a third party as development manager to manage the development and construction of improvements on the property. The construction of the campus, including three office buildings, was completed in fiscal year 2010, and serves as the Company’s headquarters.

Brocade has four operating segments. Due to the interrelation of these segments, these segments use substantially all of the properties at least in part, and Brocade retains the flexibility to use each of the properties in whole or in part for each of the segments.

Brocade’s properties are subject to a perfected first interest in and mortgages on its tangible and intangible assets as further described in Note 9 (see “Borrowing” of Note 9) of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes appearing elsewhere in this Annual Report on Form 10-K.

Overview

We are a leading supplier of end-to-end networking solutions and services for businesses and organizations of all types and sizes, including global enterprises, and service providers. Our business model is driven by our two key markets, namely our core Data Storage business, where we offer directors, switches, top-of-rack switches, end-of-row switches, HBAs, converged network products and server virtualization solutions, and our newer Ethernet business, which we acquired in December 2008 as part of our acquisition of Foundry, where we offer modular and stackable 1 GbE, 10 GbE, and 100 GbE solutions, as well as application delivery, security and wireless solutions.

Growth opportunities in the Data Storage market is expected to be driven by the requirements of key IT initiatives among enterprises such as server virtualization, data center consolidation and migration to higher performance technologies. We have recently implemented several initiatives to help drive both immediate and long-term growth in our Ethernet business. Our Ethernet business strategies are intended to increase net-new enterprise Ethernet accounts, and expand our market share. Moreover, we plan to continue to support our Data Storage and Ethernet growth plans by enhancing our existing partnerships and forming new ones, and through continuous innovation and new product introductions.

We do face challenges, some within and some outside our control, such as the uncertainty in the worldwide macroeconomic climate and its impact on IT spending patterns globally as well as the federal government budget in the United States. While the diversification of our business model helps mitigate some of these challenges and we expect IT spending levels to generally rise in the long-term, it is difficult to offset any such resulting short-term reductions of IT spending.

Going forward, we expect the number of Data Storage and Ethernet ports we ship to fluctuate depending on the demand for our existing and recently introduced Ethernet products and Data Storage products, as well as the timing of product transitions by our OEM partners. We currently expect that average selling prices per port for our Data Storage products will likely decline at rates consistent with historical rates of low single digits per quarter, and that average selling prices per port for our Ethernet products will likely decline in the low-to mid-single digits per quarter.

In an effort to increase our Ethernet revenues and increase our market share, we plan to invest in sales and marketing expenses. Also, with the completion of our Company campus, we expect reduced rent expense to benefit cash flow from operations and reduced capital expenditures. We expect our cash flows to increase in fiscal year 2011 as compared to fiscal year 2010, with which we intend to reduce our existing term loan, build cash balances and/or repurchase our Company’s stock.

Results of Operations

We report our fiscal year on a 52/53-week period ending on the last Saturday in October. As is customary for companies that use the 52/53-week convention, every fifth year contains a 53-week year. Our fiscal year 2010 is a 52-week fiscal year. Our fiscal year 2009 was a 53-week fiscal year, with our second quarter of fiscal year 2009 consisting of fourteen weeks, which was one week longer than a typical quarter. Our next 53-week fiscal year will be fiscal year 2014 and our next 14-week quarter will be in the second quarter of fiscal year 2014.

Effective November 1, 2009, we adopted a new accounting standard which required the separation of the liability and equity components of our convertible subordinated debt that may be settled in cash upon conversion

33

in a manner that reflects our economic interest cost. Accordingly, we bifurcated the debt into debt and equity components and amortized the debt discount that resulted in the “economic interest cost” in our Consolidated Statements of Operations. We have retrospectively applied the change in accounting to all periods presented, and have recast the Consolidated Financial Statements presented in this report.

During fiscal year 2010, we reviewed our cost classification, primarily related to our system engineer (“SE”) costs that were previously classified within cost of revenues. The SE’s primary role has migrated over time from assisting with customer support to primarily performing pre-sales activity to generate future business, which was enabled by the growth of our support organization, such that in 2010 the majority of the SE’s time was spent on pre-sales activity. As a result of this change, we have reclassified the SE costs within our Consolidated Statements of Operations starting in fiscal year 2010. These costs are now presented within sales and marketing expenses, as opposed to cost of revenues. Prior period amounts have not been updated for the new cost classification implemented in fiscal year 2010. See impact of this adjustment within “Gross margin (loss)” and “Sales and marketing expenses” below for comparative purposes.

Our results of operations for the years ended October 30, 2010, October 31, 2009 and October 25, 2008 are reported in this discussion and analysis as a percentage of total net revenues, except for gross margin (loss) with respect to each segment, which is indicated as a percentage of the respective segment net revenues.

Revenues. Our revenues are derived primarily from sales of our Data Storage products, sales of our Ethernet products, and our service and support offerings related to those products.

Our total net revenues are summarized as follows (in thousands, except percentages):

	Fiscal Year Ended
	October  30, 2010		% of Net Revenues			October  31, 2009		% of Net Revenues			Increase/ (Decrease)		% Change
Data Storage	$	1,243,836		59.4	%	$	1,191,077		61.0	%	$	52,759		4.4	%
Ethernet Products		488,188		23.3	%		424,434		21.7	%		63,754		15.0	%
Global Services		362,339		17.3	%		337,415		17.3	%		24,924		7.4	%
Total net revenues	$	2,094,363		100.0	%	$	1,952,926		100.0	%	$	141,437		7.2	%

	Fiscal Year Ended
	October  31, 2009		% of  Net Revenue			October  25, 2008		% of  Net Revenue			Increase/ (Decrease)			% Change
Data Storage	$	1,191,077		61.0	%	$	1,224,156		83.5	%	$	(33,079	)		(2.7	)%
Ethernet Products		424,434		21.7	%		6,581		0.4	%		417,853			6,349.4	%
Global Services		337,415		17.3	%		236,200		16.1	%		101,215			42.9	%
Total net revenues	$	1,952,926		100.0	%	$	1,466,937		100.0	%	$	485,989			33.1	%

The increase in total net revenues for the year ended October 30, 2010 compared with the year ended October 31, 2009 reflects growth in sales across all segments.

• The increase in Data Storage product revenues for the fiscal year 2010 reflects a 14.3% increase in the number of ports shipped, and mix shift from 4 Gb director and switch products to 8 Gb director and switch products, which carry a higher price per port. This was partially offset by a decrease in average selling price per port of 8.7%;

• Ethernet Products revenues for the fiscal year 2010 increased as a result of the inclusion of Foundry, which was acquired during the first fiscal quarter of 2009, for the full first fiscal quarter of 2010, and reflects the implementation of initiatives to drive both immediate and long-term growth in our Ethernet business, which offset the decrease in average selling price of approximately 12.2% during fiscal year 2010; and

34

• The increase in Global Services revenues was primarily a result of the inclusion of Foundry, which was acquired during the first fiscal quarter of 2009, for the full first fiscal quarter of 2010, and higher product revenues during fiscal year 2010.

The increase in total net revenues for the year ended October 31, 2009 compared with the year ended October 25, 2008 reflects growth in sales of Ethernet Products and Global Services offerings.

• Data Storage product revenues for the period were slightly down and reflect a 3.3% decrease in the number of ports shipped from our director and switch products and a decrease in average selling price per port of 10.4%, offset by a mix shift from 4 Gb director and switch products to 8 Gb director products, which carry a higher price per port. We believe the decline in revenues was related to the macroeconomic environment during fiscal year 2009;

• The increase in revenues from Ethernet Products was due to sales of network switching and router products acquired as part of our acquisition of Foundry in December 2008; and

• The increase in Global Services revenues was a result of the acquisition of Foundry in December 2008 and the inclusion of SBS, which was acquired in March 2008, for the full fiscal year 2009, as well as the continued expansion of our installed base.

Our total net revenues by geographical area are summarized as follows (in thousands, except percentages):

	Fiscal Year Ended
	October 30, 2010		% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)			% Change
United States	$	1,340,319		64.0	%	$	1,268,551		65.0	%	$	71,768			5.7	%

Canada, Central and South America		32,091		1.6	%		21,077		1.4	%		11,014		52.3	%
Total net revenues	$	1,952,926		100.0	%	$	1,466,937		100.0	%	$	485,989		33.1	%

(1) Includes net revenues of $254.4 million, $177.0 million and $85.1 million for the years ended October 30, 2010, October 31, 2009 and October 25, 2008 respectively, relating to the Netherlands.

International revenues increased as a percentage of total net revenues for the year ended October 30, 2010 compared with fiscal year 2009 primarily as a result of increased revenues in the Asia Pacific region. International revenues decreased as a percentage of total net revenues for the year ended October 31, 2009 compared with fiscal year 2008 primarily as a result of the higher concentration of revenue in United States associated with the Foundry acquisition. Revenues are attributed to geographic areas based on where our products are shipped. However, certain OEM partners take possession of our products domestically and then distribute these products to their international customers. Because we account for all of those OEM revenues as domestic revenues, we cannot be certain of the extent to which our domestic and international revenue mix is impacted by the practices of our OEM partners, but we believe that international revenues comprise a larger percentage of our total net revenues than the attributed revenues may indicate.

35

A significant portion of our revenue is concentrated among a relatively small number of OEM customers. For the years ended October 30, 2010, October 31, 2009 and October 25, 2008, the same three customers each represented 10% or more of our total net revenues for a combined total of 47% (EMC with 16%, HP with 14% and IBM with 17%), 48% (EMC with 18%, HP with 13% and IBM with 17%) and 65% (EMC with 25%, HP with 18% and IBM with 22%), respectively, of our total net revenues. We expect that a significant portion of our future revenues will continue to come from sales of products to a relatively small number of OEM partners and to the U.S. government or individual agencies within the U.S. government through our distributors. Therefore, the loss of, or a decrease in the level of sales to, or a change in the ordering pattern of any one of these customers could seriously harm our financial condition and results of operations.

A majority of our accounts receivable balance is derived from sales to OEM partners in the computer storage and server industry. As of October 30, 2010, three customers accounted for 17%, 14% and 10%, respectively, of total accounts receivable. As of October 31, 2009, two customers accounted for 16% and 11%, respectively, of total accounts receivable. We perform ongoing credit evaluations of our customers and generally do not require collateral or security interests on accounts receivable balances. We have established reserves for credit losses, sales allowances, and other allowances. While we have not experienced material credit losses in any of the periods presented, there can be no assurance that we will not experience material credit losses in the future.

Gross margin (loss). Gross margin (loss) as stated below is indicated as a percentage of the respective segment net revenues, except for total gross margin, which is stated as a percentage of total net revenues. Gross margin (loss) are summarized as follows (in thousands, except percentages):

	Fiscal Year Ended

Starting fiscal year 2010, gross margin excludes SE costs which have been reclassified as operating expense. For comparative purposes, had the reclassification been affected for fiscal years 2009 and 2008, the adjusted gross margins would have been as follows (in thousands, except percentages):

Total gross margin	$	1,154,046		59.1	%	$	922,139			62.9	%	$	231,907			(3.8	)%

For the year ended October 30, 2010 compared with fiscal year 2009, total gross margin increased in absolute dollars primarily due to higher revenues and exclusion of SE costs in fiscal year 2010. Total gross margin percentage also increased primarily due to the exclusion of SE costs from gross margin. Assuming the SE reclassification was made for fiscal year 2009 on a pro forma basis for comparative purposes, the total gross margin percentage decreased in fiscal year 2010 primarily due to lower Ethernet Products gross margins, as well as lower margins on Global Services, which offset the improved margins in the Data Storage segment.

Gross margin percentage by reportable segment increased or decreased for the year ended October 30, 2010 compared with fiscal year 2009 primarily due to the following factors which reflect the pro forma reclassification of SE costs in fiscal year 2009 for comparative purposes (the percentages below reflect the impact on gross margin):

• Data Storage gross margins relative to net revenues increased due to a 1.0% decrease in amortization of intangible assets related to the McDATA acquisition, and a 1.9% decrease in other manufacturing costs. This was partially offset by an increase in product costs of 0.3% relative to net revenues, primarily due to a decline in average selling price;

• Ethernet Products gross margins relative to net revenues decreased due to a 2.4% increase in product costs relative to net revenues due to lower average selling prices and shifting product mix, partially offset by cost savings, and the impact of purchase price accounting adjustment for the fiscal year 2009 related to deferred revenues. Additionally, other manufacturing costs increased 2.9% primarily on account of inventory write-downs due to product transitions, and higher manufacturing costs tied to new products; and

• Global Services gross margins relative to net revenues decreased due to a 1.3% increase in service and support costs, primarily on account of inventory write-downs in fiscal year 2010 and cash payment pursuant to a one-time settlement of a litigation matter during the first fiscal quarter of 2010. This was partially offset by a 0.6% decrease in stock-based compensation relative to net revenues.

For the year ended October 31, 2009 compared with fiscal year 2008, total gross margin increased in absolute dollars, but total gross margin percentage decreased primarily due to increased mix of Ethernet Products revenue, which carries a lower overall gross margin, purchase accounting adjustments associated with the Foundry acquisition, increased stock-based compensation and increased amortization of intangible assets acquired under the Foundry acquisition.

In addition, gross margin percentage by reportable segment increased or decreased for the year ended October 31, 2009 compared with fiscal year 2008 primarily due to the following factors, which do not reflect the pro forma reclassification of SE costs from cost of revenues to sales and marketing expenses:

• Data Storage product costs relative to net revenues slightly increased primarily due to a 3.4% increase in manufacturing costs and a 0.4% increase in stock-based compensation, both of which are due to headcount growth, partially offset by a 0.8% decrease in product costs and a 0.5% decrease in amortization of intangible assets related to the McDATA acquisition;

• Ethernet Products costs relative to net revenues decreased primarily due to an increase in revenue as a result of the Foundry acquisition, offset by an increase in product costs, amortization of intangible

37

assets and stock-based compensation. The gross loss in Ethernet Products for the year ended October 25, 2008 reflects the former Files operating segment, which has been included within the Ethernet Products reportable segment for the year ended October 31, 2009; and

• Global Services operating costs relative to net revenues decreased primarily due to a 11.2% decrease in service and support spending relative to net revenues as a result of additional revenue generated from the Foundry and SBS acquisitions, partially offset by a 1.6% increase in stock-based compensation and a 0.8% increase in amortization of intangible assets as a result of the SBS acquisition.

Gross margin is primarily affected by average selling price per port, number of ports shipped and cost of revenues. As described above, we expect that average selling prices per port for our Data Storage products will continue to decline at rates consistent with historical rates of low single digits per quarter, and the average selling price per port of our Ethernet Products will decline in the low-to mid-single digits, unless they are further affected by accelerated pricing pressures, new product introductions by us or our competitors, or other factors that may be beyond our control. We believe that we have the ability to partially mitigate the effect of declines in average selling price per port on gross margins by reducing our product and manufacturing operations costs.

Stock-based compensation expense. Stock-based compensation expense is summarized as follows (in thousands, except percentages):

	October 30, 2010		% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	101,625		4.9	%	$	137,219		7.0	%	$	(35,594	)		(25.9	)%
	October 31, 2009		% of Net Revenues			October 25, 2008		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	137,219		7.0	%	$	39,036		2.7	%	$	98,183			251.5	%

The decrease in stock-based compensation expense for the year ended October 30, 2010 compared with the fiscal year ended 2009 was primarily due to the decrease in Foundry-related deferred compensation and the completion of the Company’s long-term, performance-based equity incentive plan on October 31, 2009. The decrease was partially offset by the adoption in fiscal year 2009 of our 2009 Employee Stock Purchase Plan (“ESPP”) for which compensation expense is recognized using the graded vesting method over the twenty-four month offering period in comparison to the six-month offering period under our 1999 ESPP, which was effective for the first seven fiscal months of 2009.

The increase in stock-based compensation expense for the year ended October 31, 2009 compared with fiscal year 2008 was primarily due to increased headcount related to the acquisition of Foundry in December 2008, as well as the adoption of our 2009 ESPP for which compensation expense is recognized using the graded vesting method over the twenty-four month offering period.

Research and development expenses. Research and development (“R&D”) expenses consist primarily of salaries and related expenses for personnel engaged in engineering and R&D activities, fees paid to consultants and outside service providers, nonrecurring engineering charges, prototyping expenses related to the design, development, testing and enhancement of our products, depreciation related to engineering and test equipment, and related IT and facilities expenses.

Fiscal year ended	$	354,809		18.2	%	$	255,571		17.4	%	$	99,238			38.8	%

R&D expenses decreased for the year ended October 30, 2010 compared with the year ended October 31, 2009 due to the following:

	$ Change 2009 to 2010 Year-to-Date (“YTD”)
Salaries and wages	$	(16,150	)
Stock-based compensation		(12,570	)
The decrease in R&D expenses was partially offset by the increase in the following:
Expenses related to IT, facilities and other shared functions		8,933
Depreciation and amortization		6,805
Equipment and furniture		5,321
Outside services		5,185
Nonrecurring engineering expenses		1,518
Various individually insignificant items		409
Total change	$	(549	)

Salaries and wages decreased primarily due to lower bonuses, partially offset by headcount growth. Expenses related to IT, facilities and other shared functions increased primarily due to headcount growth and moving costs associated with preparing our new Company campus for occupancy. Depreciation and amortization increased primarily due to the build-up of our labs. Equipment and furniture increased primarily due to increased equipment purchases. Outside services increased primarily due to projects and certification costs related to our product offerings. Nonrecurring engineering expenses increased primarily due to continued development of new and enhanced products.

R&D expenses increased for the year ended October 31, 2009 compared with the year ended October 25, 2008 due to the following:

	$ Change 2008 to 2009 YTD
Salaries and wages	$	56,712

Outside services		(7,350	)
Total change	$	99,238

The increases in salaries and wages, expenses related to IT, facilities and other shared functions, nonrecurring engineering expenses, depreciation and amortization were primarily the result of headcount growth

39

from the Foundry acquisition. In addition, salaries and wages were higher for the year ended October 31, 2009 compared with fiscal year 2008 due to the extra week during the second quarter of our fiscal year 2009, partially offset by an average of nine days of unpaid time resulting from the implementation of a Company-wide unpaid time off program during fiscal year 2009.

Sales and marketing expenses. Sales and marketing expenses consist primarily of salaries, commissions and related expenses for personnel engaged in sales, marketing and customer service functions, costs associated with promotional and marketing programs, travel expenses, and related IT and facilities expenses.

Fiscal year ended	$	385,155		19.7	%	$	274,311		18.7	%	$	110,844		40.4	%

Starting fiscal year 2010, the Company classifies its SE costs as sales and marketing expenses. For comparative purposes, had the reclassification of SE costs from cost of revenues to sales and marketing expenses been affected for fiscal years 2009 and 2008, the pro forma sales and marketing expenses would have been as follows (in thousands, except percentages):

	October 30, 2010		% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)		% Change
Fiscal year ended	$	534,458		25.5	%	$	505,701		25.9	%	$	28,757		5.7	%

Fiscal year ended	$	505,701		25.9	%	$	336,078		22.9	%	$	169,623		50.5	%

Sales and marketing expenses increased for the year ended October 30, 2010 compared with the year ended October 31, 2009 due to the following, which reflects the pro forma reclassification of SE costs in fiscal year 2009 for comparative purposes:

	$ Change 2009 to 2010 YTD
System engineering costs	$	13,760
Other increases (decreases):
Expenses related to IT, facilities and other shared functions		10,930
Salaries and wages		8,409
Outside services		5,493
Travel expenses		2,584
The increase in sales and marketing expenses was partially offset by the decrease in the following:
Stock-based compensation		(11,689	)
Various individually insignificant items		(730	)
Total change	$	28,757

System engineering costs increased primary due to head count growth. Expenses related to IT, facilities and other shared functions increased primarily due to headcount growth and moving costs associated with our new

40

Company campus. Salaries and wages increased primarily due to headcount growth and higher commissions. Outside services increased primarily due to channel-related marketing and promotions and corporate brand marketing. Travel expenses increased due to headcount growth and initiatives to drive incremental revenue.

Sales and marketing expenses increased for the year ended October 31, 2009 compared with the year ended October 25, 2008 due to the following, which does not reflect the pro forma reclassification of SE costs from cost of revenues:

	$ Change 2008 to 2009 YTD
Salaries and wages	$	63,498
Stock-based compensation		38,168
Expenses related to IT, facilities and other shared functions		7,193
Outside services		4,776
Facility expenses		4,090
Various individually insignificant items		1,743
Advertising and branding expense		(8,624	)
Total change	$	110,844

The increases in salaries and wages, expenses related to IT, facilities and other shared functions, outside services and facility expenses were primarily the result of the Foundry acquisition. In addition, salaries and wages and stock-based compensation were higher for the year ended October 31, 2009 compared with fiscal year 2008 due to the extra week during the second quarter of our fiscal year 2009, partially offset by an average of nine days of unpaid time resulting from the implementation of a Company-wide unpaid time off program during fiscal year 2009. The decrease in advertising and branding expenses was primarily due to higher product launch expenses in 2008.

General and administrative expenses. General and administrative (“G&A”) expenses consist primarily of salaries and related expenses for corporate executives, finance, human resources, legal and investor relations, as well as recruiting expenses, professional fees, other corporate expenses, and related IT and facilities expenses.

G&A expenses are summarized as follows (in thousands, except percentages):

	October 30, 2010		% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)			% Change

Outside services		13,784
Depreciation and amortization		5,873
Facility expenses		4,145
Various individually insignificant items		185
Total change	$	(17,114	)

The expenses related to IT, facilities and other shared functions decreased primarily due to an increase in the amount of total expense allocated to other departments due to headcount growth in those departments. Salaries and wages decreased primarily due to lower bonuses which was partially offset by higher headcount. Outside services and facility expenses increased primarily due to costs associated with preparing our new campus for occupancy, as well as increase in outside services related to information systems projects. Depreciation and amortization increased primarily due to additional furniture and equipment and depreciation related to our new Company campus.

G&A expenses increased for the year ended October 31, 2009 compared with the year ended October 25, 2008 due to the following:

	$ Change 2008 to 2009 YTD
Stock-based compensation	$	13,436
Salaries and wages		6,202
Various individually insignificant items		4,647
Outside services		2,505
Total change	$	26,790

The increase in salaries and wages was primarily the result of headcount growth from the Foundry acquisition. In addition, salaries and wages were higher for the year ended October 31, 2009 compared with fiscal year 2008 due to the extra week during the second quarter of our fiscal year 2009, partially offset by an average of nine days of unpaid time resulting from the implementation of a Company-wide unpaid time off program during fiscal year 2009. The increase in outside services was primarily due to our enterprise reporting system integration as a result of the Foundry acquisition.

Legal fees associated with indemnification obligations and other related costs, net. These expenses consist of legal fees for various matters, including applicable indemnification obligations, defense of the Company in legal proceedings, and actions to pursue claims by the Special Litigation Committee of the Board of Directors. Pursuant to our charter documents and indemnification agreements, we had certain indemnification obligations to our directors, officers and employees, as well as certain former directors, officers and employees. As a result of such obligations and claims filed by the Special Litigation Committee of the Board of Directors, we incurred expenses related to amounts paid to certain former directors, officers and employees of the Company who have

42

been and/or are subject to ongoing SEC, civil actions and/or criminal proceedings in connection with Brocade’s historical stock option granting practices. Effective May 31, 2010, our Board of Director dissolved the Special Litigation Committee.

Legal fees associated with indemnification obligations and other related costs, net, are summarized as follows (in thousands, except percentages):

	October 30, 2010			% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)			% Change

Fiscal year ended	$	23,941			1.2	%	$	48,673		3.3	%	$	(24,732	)		(50.8	)%

Legal fees decreased for the year ended October 30, 2010 compared with fiscal year 2009 primarily due to resolution of multiple legal proceedings related to the Special Litigation Committee’s litigation.

Legal fees decreased for the year ended October 31, 2009 compared with fiscal year 2008 primarily due to resolution of multiple legal proceedings related to the Special Litigation Committee’s litigation and certain settlements received in connection with that litigation, as well as a decrease in legal expenses in connection with the litigation filed on behalf of the Company by the Special Litigation Committee of the Board of Directors.

Provision for class action lawsuit. This expense is in connection with the resolution of our class action lawsuit in fiscal year 2008. We did not record any expenses for fiscal years 2010 and 2009. Provision for class action lawsuit is summarized as follows (in thousands, except percentages):

	October 31, 2009		% of Net Revenues			October 25, 2008		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	—		—	%	$	160,000		10.9	%	$	(160,000	)		(100.0	)%

The $160.0 million in provision for class action lawsuit during the year ended October 25, 2008 was based on the preliminary settlement reached on May 30, 2008 between Brocade and the lead plaintiffs for the federal securities class action. In December 2008, we deposited $160.0 million into an escrow account on behalf of the plaintiff class to be released upon final approval of the proposed settlement by the Federal District Court. On January 26, 2009, the Federal District Court granted final approval of the settlement and the amount was released from escrow.

Amortization of intangible assets. Amortization of intangible assets is summarized as follows (in thousands, except percentages):

	October 30, 2010		% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	65,623		3.1	%	$	68,718		3.5	%	$	(3,095	)		(4.5	)%
	October 31, 2009		% of Net Revenues			October 25, 2008		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	68,718		3.5	%	$	31,484		2.1	%	$	37,234			118.3	%

During the year ended October 30, 2010, we recorded amortization of intangible assets related to the acquisitions of McDATA, Silverback, SBS and Foundry. The decrease in amortization of intangible assets for the year ended October 30, 2010 compared with fiscal year 2009 was primarily due to the full amortization of a portion of the McDATA-related intangible assets.

43

During the year ended October 31, 2009, we recorded amortization of intangible assets related to the acquisitions of McDATA, Silverback, SBS and Foundry. The increase in amortization of intangible assets for the year ended October 31, 2009 compared with fiscal year 2008 was primarily due to the acquisition of Foundry in December 2008 and the acquisition of SBS in March 2008.

Intangible assets are recorded based on estimates of fair value at the time of the acquisition and identifiable intangible assets are amortized on a straight-line basis over their estimated useful lives (see Note 4, “Goodwill and Intangible Assets,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K).

Acquisition and integration costs. Acquisition and integration costs are summarized as follows (in thousands, except percentages):

	October 30, 2010		% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	204		—	%	$	5,127		0.3	%	$	(4,923	)		(96.0	)%

Fiscal year ended	$	5,127		0.3	%	$	682		—	%	$	4,445			651.8	%

For each of the years ended October 30, 2010, October 31, 2009 and October 25, 2008, we recorded acquisition and integration costs primarily for consulting services and other professional fees in connection with our acquisition and integration of Foundry which we acquired on December 18, 2008.

Restructuring costs and facilities lease loss (benefit), net. Restructuring costs and facilities lease loss benefit, net, are summarized as follows (in thousands, except percentages):

	October 30, 2010		% of Net Revenues			October 31, 2009		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	1,059		0.1	%	$	2,329		0.1	%	$	(1,270	)		(54.5	)%
	October 31, 2009		% of Net Revenues			October 25, 2008		% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	2,329		0.1	%	$	2,731		0.2	%	$	(402	)		(14.7	)%

Restructuring costs and facilities lease loss (benefit), net, for the year ended October 30, 2010 was due to $0.5 million of restructuring costs, primarily severance payments related to certain realignment within our global services segment and $0.5 million related to estimated facility lease losses, net of expected sublease income recorded during the year ended October 30, 2010.

Restructuring costs and facilities lease loss (benefit), net, for the year ended October 31, 2009 was primarily due to $2.7 million in restructuring costs primarily related to severance payments in connection with the decision to no longer offer our suite of Files products, partially offset by a benefit of $0.3 million related to estimated facilities lease losses, net of expected sublease income, recorded during the year ended October 31, 2009. This benefit represented a change in estimate. We revised certain estimates and assumptions, including those related to estimated sublease rates, estimated time to sublease the facilities, expected future operating costs, and expected future use of the facilities.

Restructuring costs and facilities lease loss (benefit), net, for the year ended October 25, 2008 was primarily due to the restructuring of our Files business in the fourth fiscal quarter of 2008 to better align the cost structure with revenue performance, which resulted in $3.3 million in restructuring costs. This was partially offset by a benefit of $0.6 million related to estimated facilities lease losses, net of expected sublease income. This benefit represented a change in estimate associated with the reoccupation of expected sublease space by us.

In-process research and development. We did not record any in-process research and development (“IPR&D”) charge for the years ended October 30, 2010 and October 25, 2008. IPR&D for the year ended October 31, 2009 and October 25, 2008 is summarized as follows (in thousands, except percentages):

	October 31, 2009		% of Net Revenues			October 25, 2008		% of Net Revenues			Increase/ (Decrease)		% Change
Fiscal year ended	$	26,900		1.4	%	$	—		—	%	$	26,900		100.0	%

On December 18, 2008, we completed our acquisition of Foundry. In connection with this acquisition, we recorded a $26.9 million IPR&D charge (see Note 3, “Acquisitions,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K).

The IPR&D was written off because the acquired technologies had not reached technological feasibility and had no alternative uses. Technological feasibility is defined as being equivalent to completion of a beta-phase working prototype in which there is no remaining risk relating to the development. At the time of the acquisition in December 2008, Foundry was developing new products in multiple product areas that qualify as IPR&D. These efforts included FastIron SuperX Family, FastIron CX, NetIron CER, TurboIron and various other projects. Development efforts for these projects have been completed.

Goodwill and acquisition-related intangible assets impairment. We did not record any goodwill and acquisition-related intangible assets impairment for the years ended October 30, 2010 and October 25, 2008. Goodwill and acquisition-related intangible assets impairment for the year ended October 31, 2009 is summarized as follows (in thousands, except percentages):

	October 31, 2009		% of Net Revenues			October 25, 2008		% of Net Revenues			Increase/ (Decrease)		% Change
Fiscal year ended	$	53,306		2.7	%	$	—		—	%	$	53,306		100.0	%

During the second quarter of fiscal year 2009, we made a decision to no longer offer our suite of Files products. After the acquisition of Foundry, Files was combined with IP Layer 4-7/ADP to create the IP Layer 4-7/ADP operating segment. The integration of Files into the IP Layer 4-7/ADP operating segment was at a preliminary stage when the decision was made to cease development of the Files business. Accordingly, we assessed the potential impairment of the goodwill and long-lived assets relating to the Files business on a standalone basis.

As a result of the goodwill impairment analysis, we determined that all of the goodwill and acquisition-related intangible assets associated with the Files business were impaired. During the three months ended May 2, 2009, we recorded a $53.3 million impairment charge, which is comprised of a non-cash goodwill impairment charge of $45.8 million and a non-cash acquisition-related intangible assets impairment charge of $7.5 million.

Consistent with prior years, we performed our annual goodwill impairment test using measurement data as of the first day of the second fiscal quarter of 2010. The estimated fair value of IP Layer 2-3 exceeded its carrying value by approximately $58 million and the estimated fair value of IP Layer 4-7/ADP also exceeded its carrying value by approximately $58 million. The respective fair values of our remaining reporting units exceeded carrying value by a much larger amount. Based on the goodwill impairment test results, our reporting units passed step one of the impairment test and no further testing is required. The sensitivity of these test results is discussed under the “Critical Accounting Estimates” section below.

Interest and other income (loss), net. Interest and other income (loss), net, are summarized as follows (in thousands, except percentages):

	October 30, 2010			% of Net Revenues			October 31, 2009			% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	(6,452	)		(0.3	)%	$	(2,382	)		(0.1	)%	$	(4,070	)		(170.9	)%
	October 31, 2009			% of Net Revenues			October 25, 2008			% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	(2,382	)		(0.1	)%	$	26,867			1.8	%	$	(29,249	)		(108.9	)%

For the year ended October 30, 2010 compared with the corresponding periods in fiscal year 2009, the decrease in interest and other income (loss), net, was primarily due to lower interest income in fiscal year 2010 resulting from a decrease in investment balances, as well as foreign exchange losses recognized in fiscal year 2010.

For the year ended October 31, 2009 compared with the corresponding periods in fiscal year 2008, the decrease in interest and other income (loss), net, was primarily related to a decrease in investment balances due to the Foundry acquisition, as well as a $4.4 million increase in acquisition-related financing charges.

Interest expense. Interest expense primarily represents the interest cost associated with our term loan, senior secured notes and convertible subordinated debt (see Note 9, “Borrowings,” of the Notes to Consolidated Financial Statements). Interest expense is summarized as follows (in thousands, except percentages):

	October 30, 2010			% of Net Revenues			October 31, 2009			% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	(85,858	)		(4.1	)%	$	(99,294	)		(5.1	)%	$	(13,436	)		(13.5	)%
	October 31, 2009			% of Net Revenues			October 25, 2008			% of Net Revenues			Increase/ (Decrease)			% Change
Fiscal year ended	$	(99,294	)		(5.1	)%	$	(17,249	)		(1.2	)%	$	82,045			475.7	%

Interest expense decreased for the year ended October 30, 2010 compared with fiscal year 2009 primarily as a result of the Company electing to make accelerated payments towards the principal of the term loan since it was obtained in the fourth fiscal quarter of 2008 and the retirement of convertible subordinated debt on February 16, 2010.

Interest expense increased for the year ended October 31, 2009 compared with fiscal year 2008 primarily as a result of $92.3 million in interest expense incurred on the term loan and the revolving credit facility which were obtained to finance the Foundry acquisition, partially offset by capitalization of interest cost in connection with the development of our campus during the year ended October 31, 2009.

We obtained the term loan during the fourth fiscal quarter of 2008. In January 2010, we issued $600 million of long-term fixed rate notes and used the proceeds to pay down a substantial portion of the outstanding term loan, and retire the convertible subordinated debt. As of October 30, 2010 and October 31, 2009, the carrying value of the outstanding balance of our term loan was $325.9 million and $898.9 million, respectively. The Company fully paid off the principal of the convertible subordinated debt assumed from the McDATA acquisition for a total amount of $172.5 million on February 16, 2010.

Fiscal year ended	$	(602	)		(0.0	)%	$	(6,874	)		(0.5	)%	$	(6,272	)		(91.2	)%

For the year ended October 30, 2010 compared with fiscal year 2009, the increase in loss on sale of investments and property, net, was primarily related to the $8.7 million loss on the sale of owned property in San Jose during the first quarter of fiscal year 2010 to an unrelated third party (see Note 13, “Sale-Leaseback Transaction” of the Notes to Consolidated Financial Statements).

Loss on sale of investments, net, decreased for the year ended October 31, 2009 compared with fiscal year 2008. The $0.6 million in loss on sale of investments for the year ended October 31, 2009 was due to a loss of $0.6 million on the disposition of portfolio investments at amounts below the carrying value. We had a $6.9 million loss on sales of investment for the year ended October 25, 2008 due to a loss of $6.0 million on sale of our equity investments in a publicly traded company and a loss of $0.9 million on the disposition of portfolio investments at amounts below carrying value.

Loss on impairment of portfolio investments. We did not record any loss on impairment of portfolio investments for the years ended October 30, 2010 and October 31, 2009. Loss on impairment of portfolio investments for fiscal year ended October 25, 2008 is summarized as follows (in thousands, except percentages):

As of October 25, 2008, we determined that the declines in the fair value for certain of our portfolio investments primarily associated with non-marketable investments were other than temporary due to the significant deterioration of the financial condition of the investees. As a result, for the year ended October 25, 2008, we recorded impairment charges of $8.8 million.

Income tax provision (benefit). Income tax provision (benefit) and the effective tax rates are summarized as follows (in thousands, except effective tax rates):

Effective tax rate		(7.9	)%		(10.0	)%		(636.1	)%

We recorded a tax benefit for the year ended October 30, 2010 compared to a tax provision in fiscal year 2009 primarily due to the following on a net basis (additionally, see Note 15, “Income Taxes,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K):

• A benefit from the release of certain reserves relates to the settlement of the Company’s fiscal year 2003 IRS audit;

• A benefit from the release of pre fiscal year 2005 California R&D credit reserves as a result of the Notice of Proposed Adjusted Carryover Amount issued by the FTB;

47

• A benefit from the release of certain reserves relating to foreign subsidiaries;

• A benefit from the confirmation by the U.S. Court of Appeals for the Ninth Circuit of the tax court’s decision in Xilinx, Inc. v. Commissioner related to certain stock option treatment;

• A benefit from the recent IRS decision to concede the intercompany gross receipts issue for R&D credit calculations;

• A benefit from the settlement of the Foundry IRS audit;

• A nonrecurring loss on the sale of property; and

• A benefit from a law change allowing 5-year carryback on net operating losses as a result of the American Recovery and Reinvestment Act of 2009 effective on November 20, 2009; partially offset by

• The lapse of the Federal R&D credit periods after December 31, 2009.

Based on the fiscal year 2011 financial forecast, we currently expect the effective tax rate to be higher than fiscal year 2010. As estimates and judgments are used to project such domestic and international earnings, the impact to our tax provision could vary if the current planning or assumptions change. Given that the tax rate is driven by several different factors, it is not possible to estimate our future tax rate with a high degree of certainty.

Our effective tax rate increased for the year ended October 31, 2009 compared with fiscal year 2008 primarily due to a one-time valuation allowance release in the second fiscal quarter of 2008.

To the extent that international revenues and earnings differ from those historically achieved, a factor largely influenced by the buying behavior of our customers and OEM partners or by unfavorable prospective and retrospective effects of changing tax laws and regulations, our income tax provision could change.

Estimates and judgments are required in the determination of the recoverability of certain deferred tax assets, which arise from variable stock option expense, net operating losses, tax carry forwards and temporary differences between the tax and financial statement recognition of revenues and expenses.

We apply a recognition threshold and measurement attribute for the financial statement recognition and measurement of an income tax position taken or expected to be taken on a tax return. Recognition of a tax position is determined when it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority.

The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. The threshold and measurement attribute we apply for the accounting for uncertainty in income taxes recognized in the financial statements will continue to require significant judgment by management. Resolution of these uncertainties in a manner inconsistent with our expectations could have a material impact on our results of operations.

The IRS and other tax authorities regularly examine our income tax returns. We are currently under negotiations with the Appeals division of the IRS for the audit of fiscal years 2004 through 2006, which we expect to resolve during the next twelve months. In addition, we are in negotiations with the foreign tax authorities to receive collateral relief on transfer pricing settlements with the IRS. We believe that our reserves for unrecognized tax benefits are adequate for open tax years. The timing of the resolution of income tax examinations, as well as the amounts and timing of related settlements, is highly uncertain. The Company believes that before the end of fiscal year 2011, it is reasonably possible that either certain audits will conclude or the statute of limitations relating to certain income tax examination periods will expire, or both. Given the

48

uncertainty as to settlement terms, the timing of payments and the impact of such settlements on other uncertain tax positions, the range of estimated potential decreases in underlying uncertain tax positions is between $0 and $15 million. For additional discussion, see Note 15, “Income Taxes,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

Liquidity and Capital Resources

	October 30, 2010			October 31, 2009			Increase/ (Decrease)
	(in thousands)			(in thousands)
Cash and cash equivalents	$	333,984		$	334,193		$	(209	)
Short-term investments		1,998			4,678			(2,680	)
Restricted cash		—			12,502			(12,502	)
Total	$	335,982		$	351,373		$	(15,391	)
Percentage of total assets		9	%		10	%

We use cash generated by operations as our primary source of liquidity. We expect that cash provided by operating activities may fluctuate in future periods as a result of a number of factors, including fluctuations in our operating results, the rate at which products are shipped during the quarter, accounts receivable collections, inventory and supply chain management, and the timing and amount of tax and other payments. For additional discussion, see “Part I—Item 1A. Risk Factors.”

Based on past performance and current expectations, we believe that internally generated cash flows are generally sufficient to support business operations, capital expenditures, contractual obligations, and other liquidity requirements associated with our operations for at least the next twelve months. Also, we have up to $125 million available under our revolving credit facility, and we can factor our trade receivables up to the maximum amount available at any time of our $50 million factoring facility to provide additional liquidity. We paid off our convertible subordinated debt due on February 15, 2010 through our existing cash on hand, together with proceeds from the Senior Secured Notes issued on January 20, 2010. There are no other transactions, arrangements, or other relationships with unconsolidated entities or other persons that are reasonably likely to materially affect liquidity and the availability of and our requirements for capital resources.

Financial Condition

Cash and cash equivalents, restricted cash and short-term investments as of October 30, 2010 decreased by $15.4 million over the balance as of October 31, 2009 primarily due to the accelerated payments towards the principal of the term loan and payments made to retire our convertible subordinated debt and revolving credit facility, as well as increased purchases of property and equipment, and shares we repurchased during the fiscal year ended October 30, 2010, partially offset by proceeds from our senior secured notes and increased cash provided by operating activities. For the fiscal ended October 30, 2010, we generated $298.5 million in cash from operating activities, which was higher than our net income for the same period primarily as a result of adjustments to net income for non-cash items related to depreciation and amortization, amortization of debt issuance costs and stock-based compensation expense, partially offset by a decrease in accounts payable, and accrued employee compensation and an increase in accounts receivable.

Accounts receivable days sales outstanding, which is a measure of the average number of days that a company takes to collect revenue after a sale has been made, for the year ended October 30, 2010 was 57 days, flat from 57 days for the year ended October 31, 2009.

Net cash used in investing activities for the year ended October 30, 2010 totaled $168.4 million and was primarily the result of $201.6 million in purchase of property and equipment, offset by $30.2 million in proceeds resulting from the sale of property.

49

Net cash used in financing activities for the year ended October 30, 2010 totaled $127.7 million and was primarily the result of payment of principal related to the term loan of $583.0 million, payment to retire the convertible subordinated debt and revolving credit facility of $172.5 million and $14.1 million, respectively, and common stock repurchases of $25.0 million, partially offset by net proceeds from the issuance of Senior Secured Notes of $588.0 million and proceeds from the issuance of common stock from ESPP purchases and stock option exercises of $81.6 million.

Net proceeds from the issuance of common stock in connection with employee participation in our equity compensation plans have historically been a significant component of our liquidity. The extent to which our employees participate in these programs generally increases or decreases based upon changes in the market price of our common stock. As a result, our cash flow resulting from the issuance of common stock in connection with employee participation in equity compensation plans will vary.

Fiscal Year 2010 Compared to Fiscal Year 2009

Operating Activities. Net cash provided by operating activities increased by $183.0 million for the year ended October 30, 2010 compared with fiscal year 2009. The increase was primarily due to an increase in net income, and the $160.0 million payment of the liability associated with the settlement of the class action lawsuit in fiscal year 2009. This increase was partially offset by a decrease in accrued employee compensation, and accounts payable during fiscal year 2010.

Investing Activities. Net cash used in investing activities decreased by $30.7 million for the year ended October 30, 2010 compared with fiscal year 2009. The decrease was primarily due to cash paid in connection with the Foundry acquisition during the fiscal year ended October 31, 2009 and increased proceeds from the sale of property during the fiscal year ended October 30, 2010. This decrease was partially offset by a decrease in restricted cash which was released to finance a portion of the Foundry acquisition, as well as increased purchase of property and equipment and decreased proceeds from maturities and sale of short-term and long-term investments.

Financing Activities. Net cash used in financing activities increased by $90.1 million for the year ended October 30, 2010 compared with fiscal year 2009. The increase was primarily due to increased payment of principal related to the term loan, payment to retire the convertible subordinated debt and revolving credit facility, decreased proceeds from the issuance of common stock, and increased common stock repurchases made during the year ended October 30, 2010, partially offset by increased proceeds from the issuance of Senior Secured Notes and decreased payment of senior underwriting fees related to the term loan.

Fiscal Year 2009 Compared to Fiscal Year 2008

Operating Activities. Net cash provided by operating activities decreased by $323.0 million for the year ended October 31, 2009 compared with fiscal year 2008. The decrease was primarily due to net loss, the $160.0 million payment of the liability associated with the settlement of the class action lawsuit, decreased accounts receivable collections and increased payments with respect to accounts payable, accrued employee compensation and other accrued liabilities during the year ended October 31, 2009.

Investing Activities. Net cash used in investing activities decreased by $1,040.4 million for the year ended October 31, 2009 compared with fiscal year 2008. The decrease was primarily due to a decrease in restricted cash which was released to finance a portion of the Foundry acquisition, as well as decreased purchases of investments and marketable equity securities as we continued to prioritize our use of cash for debt repayment. The decrease was partially offset by cash paid in connection with the Foundry acquisition and decreased proceeds from the maturities and sales of investments and marketable equity securities.

Financing Activities. Net cash provided by financing activities decreased by $982.3 million for the year ended October 31, 2009 compared with fiscal year 2008. The decrease was primarily due to the proceeds

50

received in fiscal year 2008 from the term loan and the payment of principal and senior underwriting fees in fiscal year 2009 related to the term loan, partially offset by decreased common stock repurchases and increased proceeds from the issuance of common stock from ESPP and stock option exercises, and proceeds from the revolving credit facility.

Liquidity

Manufacturing and Purchase Commitments. We have manufacturing arrangements with contract manufacturers under which we provide twelve-month product forecasts and place purchase orders in advance of the scheduled delivery of products to our customers. Our purchase commitments reserve reflects our estimate of purchase commitments we do not expect to consume in normal operations within the next twelve months, in accordance with our policy (see Note 10, “Commitments and Contingencies,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K).

Company Campus Contractual Obligations. On May 23, 2008, we purchased property located in San Jose, California, which consisted of three unimproved building parcels that were entitled for approximately 562,000 square feet of space in three buildings. Construction of the Company campus was completed in third fiscal quarter of 2010 and serves as the Company’s headquarters. For additional discussion, see Note 10, “Commitments and Contingencies,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

Income Taxes. We accrue U.S. income taxes on the earnings of our foreign subsidiaries unless the earnings are considered indefinitely reinvested outside of the United States. We intend to reinvest current and accumulated earnings of our foreign subsidiaries for expansion of our business operations outside the United States for an indefinite period of time.

The IRS and other tax authorities regularly examine our income tax returns (see Note 15, “Income Taxes,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K). We believe we have adequate reserves for all open tax years.

Senior Secured Credit Facility. A portion of our outstanding debt is related to the financing of the Foundry acquisition, the costs and expenses related to the merger, and the ongoing working capital and other general corporate purposes of the combined organization after consummation of the merger (see Note 9, “Borrowings,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K). We have the following resources available to obtain short-term or long-term financing, if we need additional liquidity, as of October 30, 2010 (in thousands):

	Original Amount Available		October 30, 2010
			Used		Available
Revolving credit facility	$	125,000	$	—	$	125,000
Total	$	125,000	$	—	$	125,000

Trade Receivables Factoring Facility. We have an agreement with a financial institution to sell certain of our trade receivables from customers with limited, non-credit related, recourse provisions. The sale of receivables eliminates our credit exposure in relation to these receivables. Total trade receivables sold under our factoring facility are summarized as follows (in thousands):

	Fiscal Year Ended
	October 30, 2010		October 31, 2009
Trade receivables sold under factoring agreement	$	61,408	$	—

51

Under the terms of the factoring agreement, the remaining available amount of the factoring facility as of October 30, 2010 is $25.9 million.

Senior Secured Notes. In January 2010, we issued $600 million of long-term fixed rate notes and used the proceeds to pay down a substantial portion of the outstanding term loan, and retire the convertible subordinated debt due on February 15, 2010 (see Note 9, “Borrowings,” of the Notes to Consolidated Financial Statements).

Contractual Obligations

The following table summarizes our contractual obligations, including interest expense, and commitments as of October 30, 2010 (in thousands):

	Total		Less than 1 Year		1 – 3 Years		3 – 5 Years		More than 5 Years

Unrecognized tax benefits and related accrued interest (5)	$	139,812	$	n/a	$	n/a	$	n/a	$	n/a

(1) Amount reflects total anticipated cash payments, including anticipated interest payments.

(2) Amount excludes contractual sublease income of $39.5 million, which consists of $5.5 million to be received in less than one year, $12.8 million to be received in one to three years, $13.6 million to be received in three to five years and $7.6 million to be received in more than five years.

(3) Amount reflects total gross purchase commitments under our manufacturing arrangements with third-party contract manufacturers. Of this amount, we have accrued $4.9 million for estimated purchase commitments that we do not expect to consume in normal operations within the next twelve months, in accordance with our policy.

(4) Amount reflects $10.4 million in capital expenditures in connection with the development of the corporate campus.

(5) As of October 30, 2010, we had a liability for unrecognized tax benefits of $136.8 million and a net accrual for the payment of related interest and penalties of $3.0 million. We expect to resolve the fiscal year 2004 through 2006 IRS audit during the next twelve months. As such, after we reach settlement with the IRS, we expect to record a corresponding adjustment to our unrecognized tax benefits. Due to availability of net operating losses, the IRS audit settlement is not expected to result in a significant tax payment. Other than the expected 2004 to 2006 settlement, we are unable to make a reasonably reliable estimate of the timing of payments in individual years due to uncertainties in the timing of tax audit outcome.

Share Repurchase Program. As of November 29, 2007, our Board of Directors authorized a total of $800.0 million for the repurchase of our common stock. The purchases may be made, from time to time, in the open market or by privately negotiated transactions and will be funded from available working capital. The number of shares to be purchased and the timing of purchases will be based on the level of our cash balances, general business and market conditions, and other factors, including alternative investment opportunities. For the year

52

ended October 30, 2010, we repurchased 4.5 million shares for an aggregate purchase price of $25.0 million. Approximately $389.1 million remains authorized for future repurchases under this program as of October 30, 2010. We are subject to certain covenants relating to our borrowings that restrict the amount of our Company’s shares that we can repurchase. As of October 30, 2010, we can repurchase up to an additional $75 million of our Company’s shares under the terms of our senior secured credit facility, provided our consolidated senior secured leverage ratio as defined in the credit agreement is under 2.00. We made no repurchases for the year ended October 31, 2009 due to prioritizing our use of cash for debt repayment following the close of the Foundry acquisition.

Off-Balance Sheet Arrangements

As part of our ongoing business, we do not participate in transactions that generate material relationships with unconsolidated entities or financial partnerships, such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or for other contractually narrow or limited purposes. As of October 30, 2010, we did not have any significant off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of SEC Regulation S-K.

Critical Accounting Estimates

Our discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these Consolidated Financial Statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We evaluate, on an ongoing basis, our estimates and judgments, including, but not limited to, those related to sales allowances and programs, bad debts, stock-based compensation, allocation of purchase price of acquisitions, excess inventory and purchase commitments, restructuring costs, facilities lease losses, impairment of goodwill and intangible assets, litigation, income taxes and investments. We base our estimates on historical experience and assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

The methods, estimates and judgments we use in applying our most critical accounting policies have a significant impact on the results that we report in our Consolidated Financial Statements. We believe the following critical accounting policies, among others, require significant estimates and judgments used in the preparation of our consolidated financial statements.

Revenue recognition. Our multiple-element product offerings include networking hardware with embedded software products and support, which are considered separate units of accounting. For certain of our products, software and non-software components function together to deliver the tangible products’ essential functionality. We allocate revenue to each element in a multiple-element arrangement based upon their relative selling price. When applying the relative selling price method, we determine the selling price for each deliverable using vendor-specific objective evidence (“VSOE”) of selling price, if it exists, or third-party evidence (“TPE”) of selling price. If neither VSOE nor TPE of selling price exist for a deliverable, we use our best estimate of selling price for that deliverable. Revenue allocated to each element is then recognized when the basic revenue recognition criteria are met for each element.

Consistent with our methodology under previous accounting guidance, we determine VSOE based on our normal pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, we require that a substantial majority of the selling prices for a product or service fall within a reasonably narrow pricing range, generally evidenced by approximately 80% of such historical stand-alone transactions falling within ±15% of the median rates. For post-contract customer support, however, we consider stated renewal rates in determining VSOE.

53

In most instances, we are not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to us infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, we attempt to establish selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, our go-to-market strategy differs from that of our peers and our offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, we are unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, we are typically not able to determine TPE.

When we are unable to establish selling price using VSOE or TPE, we use estimated selling price (“ESP”) in our allocation of the arrangement consideration. The objective of ESP is to determine the price at which we would transact a sale if the product or service were sold on a stand-alone basis. ESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings.

We determine ESP for a product or service by considering multiple factors including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives and pricing practices. The determination of ESP is made through consultation with and formal approval by our management, taking into consideration the go-to-market strategy. If circumstances related to our estimates for revenue recognition change, our allocation of revenue to each element in a multiple-element arrangement may also change.

Stock-based compensation. We grant stock options for shares in the Company’s common stock, restricted stock units and other types of equity compensation awards to our employees and directors under various equity compensation plans. For additional discussion, see Note 14, “Stock-Based Compensation,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

The compensation expense for stock-based awards is adjusted for an estimated impact of forfeitures and is recognized over the expected term of the award under a graded vesting method. In addition, we record stock-based compensation expense in connection with shares issued under our employee stock purchase plan using the graded vesting method over the twenty-four month offering period.

We use the Black-Scholes option pricing model to determine the fair value of stock options granted when the measurement date is certain. We also use the Black-Scholes option pricing model to determine the fair value of the option component of employee stock purchase plan shares. The determination of the fair value of stock-based awards using the option pricing model is affected by our stock price as well as assumptions regarding a number of complex and subjective variables. These variables include our expected stock price volatility over the expected term of the awards, projected and actual employee stock option exercise behaviors, risk-free interest rates, estimated forfeitures and expected dividends.

We estimate the expected term of stock options granted by calculating the average term from our historical stock option exercise experience. We do not anticipate paying any cash dividends in the foreseeable future, and therefore we use an expected dividend yield of zero in the option pricing model. We are required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. We use historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. We use implied volatilities from traded options of the Company’s common stock and historical volatilities of the Company’s common stock to estimate volatility over the expected term of the awards.

The assumptions used in calculating the fair value of stock-based awards represent management’s best estimates, but these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and we use different assumptions, our stock-based compensation expense could be materially different in the future.

54

Acquisitions—Purchase Price Allocation. We allocate the purchase price of an acquired business to the assets acquired and liabilities assumed, including identifiable intangible assets, based on their respective fair values at the acquisition date. The excess of the purchase price over the fair value of the underlying acquired net tangible and intangible assets, if any, is recorded as goodwill. Management estimates the fair value of assets and liabilities based upon quoted market prices, the carrying value of the acquired assets and widely accepted valuation techniques. We adjust the preliminary purchase price allocation, as necessary, typically up to one year after the acquisition closing date as we obtain more information regarding asset valuations and liabilities assumed. For additional discussion, see Note 3, “Acquisitions,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

Inventory valuation and purchase commitment liabilities. We write down inventory and record purchase commitment liabilities for estimated excess and obsolete inventory equal to the difference between the cost of inventory and the estimated fair value based upon forecast of future product demand, product transition cycles and market conditions. Any significant unanticipated changes in demand or technological development could have a significant impact on the value of our inventory and purchase commitments, and our reported results. If actual market conditions are less favorable than those projected, additional inventory write-downs, purchase commitment liabilities and charges against earnings may be required. For additional discussion, see Note 10, “Commitments and Contingencies,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

Restructuring costs and facilities lease losses. We monitor and regularly evaluate our organizational structure and associated operating expenses. Depending on events and circumstances, we may decide to take additional actions to reduce future operating costs as our business requirements evolve. In determining restructuring charges, we analyze our future operating requirements, including the required headcount by business functions and facility space requirements. Our restructuring costs and any resulting accruals involve significant estimates made by management using the best information available at the time the estimates are made. In recording severance accruals, we record a liability when all of the following conditions have been met: employees’ rights to receive compensation for future absences is attributable to employees’ services already rendered; the obligation relates to rights that vest or accumulate; payment of the compensation is probable; and the amount can be reasonably estimated. In recording facilities lease loss accruals, we make various assumptions, including the time period over which the facilities are expected to be vacant, expected sublease terms, expected sublease rates, expected future operating costs, and expected future use of the facilities. Our estimates involve a number of risks and uncertainties, some of which are beyond our control, including future real estate market conditions and our ability to successfully enter into subleases or lease termination agreements with terms as favorable as those assumed when arriving at our estimates. We regularly evaluate a number of factors to determine the appropriateness and reasonableness of our restructuring and facilities lease loss accruals, including the various assumptions noted above. If actual results differ significantly from our estimates, we may be required to adjust our restructuring and facilities lease loss accruals in the future. For additional discussion, see Note 5, “Liabilities Associated with Facilities Lease Losses,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

Impairment of goodwill and intangible assets. Goodwill is generated as a result of business combinations. We conduct our goodwill impairment test annually, as of the first day of the second fiscal quarter, or whenever events or changes in facts and circumstances indicate that the fair value of the reporting unit may be less than its carrying amount. Events which might indicate impairment include, but are not limited to, strategic decisions made in response to economic and competitive conditions, the impact of the economic environment on our customer base, material negative changes in relationships with significant customers, and/or a significant decline in our stock price for a sustained period. For additional discussion, see Note 4, “Goodwill and Intangible Assets,” of the Notes to Consolidated Financial Statements in Part II, Item 8 of this Form 10-K.

We apply a two-step approach in testing goodwill for impairment for each reporting unit, which we have determined to be at the operating segment level. The reporting units are determined by the components of our

55

operating segments that constitute a business for which both (i) discrete financial information is available and (ii) segment management regularly reviews the operating results of that component. Data Storage, IP Layer 2-3, which includes Open System Interconnection Reference Model (“OSI”) Layer 2-3 products, IP Layer 4-7/ADP, which includes OSI Layer 4-7 products, and Global Services are our four reporting units.

The first step tests for potential impairment by comparing the fair value of reporting units with reporting units’ net asset values. If the fair value of the reporting unit exceeds the carrying value of the reporting unit’s net assets, then goodwill is not impaired and no further testing is required. If the fair value of reporting unit is below the reporting unit’s carrying value, then the second step is required to measure the amount of potential impairment. The second step requires an assignment of the reporting unit’s fair value to the reporting unit’s assets and liabilities, using the initial acquisition accounting guidance in ASC 805 Business Combinations, to determine the implied fair value of the reporting unit’s goodwill. The implied fair value of the reporting unit’s goodwill is then compared with the carrying amount of the reporting unit’s goodwill to determine the goodwill impairment loss to be recognized, if any. If the carrying value of a reporting unit’s goodwill exceeds its implied fair value, we record an impairment loss equal to the difference.

To determine the reporting unit’s fair values, we use the income approach, the market approach, or a combination thereof. The income approach provides an estimate of fair value based on discounted expected future cash flows. The market approach provides an estimate of the fair value of our four reporting units using various price or market multiples applied to the reporting unit’s operating results and then applying an appropriate control premium. During our fiscal year 2010 annual goodwill impairment test under the first step, we used a combination of approaches to estimate reporting units’ fair values, but we relied primarily on the income approach results, using management’s recent, post-recession cash flow projections for each reporting unit and risk-adjusted discount rates. We believe that the income approach is more representative of reporting units’ fair value compared to market approach results due to conditions of current financial markets and other market factors.

Determining the fair value of a reporting unit or an intangible asset is judgmental in nature and involves the use of significant estimates and assumptions. We based our fair value estimates on assumptions we believe to be reasonable, but that are unpredictable and inherently uncertain. Estimates and assumptions with respect to the determination of the fair value of our reporting units using the income approach include, among other inputs:

• Our operating forecasts;

• Revenue growth rates; and

• Risk-commensurate discount rates and costs of capital.

Our estimates of revenues and costs are based on historical data, various internal estimates and a variety of external sources, and are developed as part of our regular long-range planning process. The control premium used in market or combined approaches is determined by considering control premiums offered as part of acquisitions that have occurred in a reporting unit’s comparable market segments.

Based on our step one analysis results, we believe that all our reporting units pass the step one test and no further testing is required. However, because some of the inherent assumptions and estimates used in determining the fair value of these reportable segments are outside the control of management, changes in these underlying assumptions can adversely impact fair value. The sensitivity analysis below quantifies the impact of key assumptions on our reporting units’ fair value estimates. The principal key assumptions impacting our estimates were (i) discount rates and (ii) discounted expected future cash flows (“DCF”) terminal value multipliers. As the discount rates, ultimately, reflect the risk of achieving reporting units’ revenue and cash flow projections, we don’t believe that a separate sensitivity analysis for changes in revenue and cash flow projections is meaningful or useful.

The estimated fair value of IP Layer 2-3 reporting unit exceeded its carrying value by approximately $58 million and the estimated fair value of IP Layer 4-7/ADP reporting unit also exceeded its carrying value by approximately $58 million. The respective fair values of our remaining reporting units exceeded carrying value by significant amounts and were not subject to the sensitivity analysis presented below.

The following table summarizes the approximate impact that a change in principal key assumptions would have on the estimated fair value of IP Layer 2-3 reporting unit, leaving all other assumptions unchanged:

	Change			Approximate Impact  on Fair Value (In millions)		Excess of Fair Value over Carrying Value (In millions)
Discount rate		±1	%	$	(47) – 50	$	11 – 108
DCF terminal value multiplier		±0.5x		$	(41) – 41	$	17 – 99

The following table summarizes the approximate impact that a change in principal key assumptions would have on the estimated fair value of IP Layer 4-7/ADP reporting unit, leaving all other assumptions unchanged:

	Change			Approximate Impact  on Fair Value (In millions)		Excess of Fair Value over Carrying Value (In millions)
Discount rate		±1	%	$	(11) – 12	$	47 – 70
DCF terminal value multiplier		±0.5x		$	(11) – 11	$	47 – 69

Accounting for income taxes. The determination of our tax provision is subject to estimates and judgments due to operations in multiple tax jurisdictions inside and outside the United States. Sales to our international customers are principally taxed at rates that are lower than the United States statutory rates. The ability to maintain our current effective tax rate is contingent upon existing tax laws in both the United States and in the respective countries in which our international subsidiaries are located. Future changes in domestic or international tax laws could affect the continued realization of the tax benefits we are currently receiving and expect to receive from international sales. In addition, an increase in the percentage of our total revenue from international customers or in the mix of international revenue among particular tax jurisdictions could change our overall effective tax rate. Also, our current effective tax rate assumes that United States income taxes are not provided for undistributed earnings of certain non-United States subsidiaries. These earnings could become subject to United States federal and state income taxes and foreign withholding taxes, as applicable, should they be either deemed or actually remitted from our international subsidiaries to the United States. In addition, we evaluate the expected realization of our deferred tax assets and assess the need for a valuation allowance on a quarterly basis. As of October 30, 2010, our net deferred tax asset balance was 270.5 million. We believe that sufficient positive evidence exists from historical operations and projections of U.S. taxable income in future years to conclude that it is more likely than not that we would realize our deferred tax assets. Historical operations were impacted by discrete events that if excluded would show that we have cumulative profits for the prior 12 quarters ended October 30, 2010. Accordingly, we only apply a valuation allowance on the deferred tax assets relating to capital loss and investments loss carryforwards due to limited carrforward periods and the character of such tax attributes. In the event future income by jurisdiction is less than what is currently projected, we may be required to apply a valuation allowance to these deferred tax assets in jurisdictions for which realization is no longer determined to be more likely than not.

Accounting for uncertain tax benefits. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. We apply a recognition threshold and measurement attribute for financial statement disclosure of tax positions taken or expected to be taken on a tax return. Recognition of a tax position is determined when it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is

57

greater than 50% likely of being realized upon ultimate settlement with a taxing authority. The threshold and measurement attribute requires significant judgment by management. Resolution of these uncertainties in a manner inconsistent with our expectations could have a material impact on our results of operations.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

In the normal course of business, we are exposed to market risks related to changes in interest rates, foreign currency exchange rates and equity prices that could impact our financial position and results of operations. Our risk management strategy with respect to these three market risks may include the use of derivative financial instruments. We use derivative contracts only to manage existing underlying exposures of the Company. Accordingly, we do not use derivative contracts for speculative purposes. Our risks and risk management strategy are outlined below. Actual gains and losses in the future may differ materially from the sensitivity analyses presented below based on changes in the timing and amount of interest rates and our actual exposures and hedges.

Interest Rate Risk

Our exposure to market risk due to changes in the general level of United States interest rates relates primarily to our term loan and cash equivalents.

We are exposed to changes in interest rates as a result of our borrowings under our term loan. As of October 30, 2010, the weighted-average interest rate on the term loan was 7.0%, which represents the minimum interest rate under the credit agreement. The current market rates are such that a 1% increase in market rates would still result in a 7.0% interest rate on the term loan. However, based on outstanding principal indebtedness of $350.9 million under our term loan as of October 30, 2010, if market rates average 1% above the interest rate floor over the remaining term of the debt, which would result from an increase in market rates of approximately 3.2%, our annual interest expense would increase by approximately $7.6 million.

Our cash and cash equivalents are primarily maintained at five major financial institutions in the United States. The primary objective of our investment activities is the preservation of principal while maximizing investment income and minimizing risk.

The Company did not have any material investments as of October 30, 2010 and October 31, 2009 that are sensitive to changes in interest rates.

Foreign Currency Exchange Rate Risk

We are exposed to foreign currency exchange rate risk inherent in conducting business globally in numerous currencies, of which the most significant to our operations for fiscal year 2010 were the Chinese yuan, the euro, the Japanese yen, the British pound, the Singapore dollar and the Swiss franc. We are primarily exposed to foreign currency fluctuations related to operating expenses and cost of inventory components denominated in currencies other than the U.S. dollar. As such, we benefit from a stronger U.S. dollar and may be adversely affected by a weaker U.S. dollar relative to the foreign currency. We use foreign currency forward contracts designated as cash flow hedges to protect against the foreign currency exchange rate risks inherent in our forecasted operating expenses denominated in currencies other than the U.S. dollar. We recognize the gains and losses on foreign currency forward contracts in the same period as the remeasurement losses and gains of the related foreign currency denominated exposures.

We also may enter into other non-designated derivatives that consist primarily of forward contracts to minimize the risk associated with the foreign exchange effects of revaluing monetary assets and liabilities. Monetary assets and liabilities denominated in foreign currencies and any associated outstanding forward contracts are marked-to-market with realized and unrealized gains and losses included in “Other income (loss), net.”

Alternatively, we may choose not to hedge the foreign currency risk associated with our foreign currency exposures if such exposure acts as a natural foreign currency hedge for other offsetting amounts denominated in

59

the same currency or if the currency is difficult or too expensive to hedge. As of October 30, 2010, we held $112.0 million in cash flow derivative instruments denominated in the Euro, Japanese yen, British pound, Singapore dollar and Swiss franc. The maximum length of time over which we are hedged as of October 30, 2010 is through November 4, 2011.

We have performed a sensitivity analysis as of October 30, 2010, using a modeling technique that measures the change in the fair values arising from a hypothetical 10% adverse movement in the levels of foreign currency exchange rates relative to the U.S. dollar, with all other variables held constant. The analysis covers all of our foreign currency contracts offset by the underlying exposures. The foreign currency exchange rates we used were based on market rates in effect at October 30, 2010. The sensitivity analysis indicated that a hypothetical 10% adverse movement in foreign currency exchange rates would not result in a material foreign exchange loss as of October 30, 2010.

Equity Price Risk

We had no investments in publicly traded equity securities as of October 30, 2010 and October 31, 2009. We monitor our equity investments for impairment on a periodic basis. In the event that the carrying value of the equity investment exceeds its fair value, and we determine the decline in value to be other-than-temporary, we reduce the carrying value to its current fair value. Generally, we do not attempt to reduce or eliminate our market exposure on these equity securities. We do not purchase our equity securities with the intent to use them for speculative purposes. The aggregate cost of our equity investments in non-publicly traded companies was $7.0 million and $6.8 million at October 30, 2010 and October 31, 2009.

Our common stock is quoted on the NASDAQ Global Select Market under the symbol “BRCD.” On October 29, 2010, the last business day of our fourth fiscal quarter of 2010, the last reported sale price of our common stock on the NASDAQ Global Select Market was $6.35 per share.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Brocade Communications Systems, Inc.:

We have audited the accompanying consolidated balance sheets of Brocade Communications Systems, Inc. and subsidiaries (the Company) as of October 30, 2010 and October 31, 2009, and the related consolidated statements of operations, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended October 30, 2010. In connection with our audit of the consolidated financial statements, we also have audited the accompanying financial statement schedule. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the auditing 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, 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 consolidated financial statements referred to above present fairly, in all material respects, the financial position of Brocade Communications Systems, Inc. and subsidiaries as of October 30, 2010 and October 31, 2009, and the results of their operations and their cash flows for each of the years in the three-year period ended October 30, 2010, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.

As discussed in note 2 to the consolidated financial statements, the Company adopted new accounting standards for convertible debt instruments and revenue recognition as of November 1, 2009. The Company also changed its method of accounting for uncertainty in income taxes and recorded a cumulative effect adjustment as of the beginning of the year ended October 25, 2008.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the Company’s internal control over financial reporting as of October 30, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated December 17, 2010 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of Presentation and Reclassification

The fiscal year for Brocade Communications Systems, Inc. (“Brocade” or the “Company”) is the 52 or 53 weeks ending on the last Saturday in October. As is customary for companies that use the 52/53-week convention, every fifth year contains a 53-week year. Fiscal year 2010 is a 52-week fiscal year and fiscal year 2009 and 2008 were 53-week and 52-week fiscal years, respectively. The second quarter of fiscal year 2009 consisted of fourteen weeks, which was one week longer than a typical quarter. The Company’s next 53-week fiscal year will be fiscal year 2014 and our next 14-week quarter will be in the second quarter of fiscal year 2014. The Consolidated Financial Statements include the accounts of Brocade and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated.

Reclassification

During fiscal year 2010, we reviewed our cost classification, primarily related to our system engineer (“SE”) costs that were previously classified within cost of revenues. The SE’s primary role has migrated over time from assisting with customer support to primarily performing pre-sales activity to generate future business, which was enabled by the growth of our support organization, such that in 2010 the majority of the SE’s time was spent on pre-sale activity. As a result of this change, we have reclassified the SE costs within our Consolidated Statements of Operations starting in fiscal year 2010. These costs are now presented within sales and marketing expenses, as opposed to cost of revenues. This reclassification did not impact revenues, income from operations, net income, or earnings per share for 2010. Prior period amounts have not been updated for the new cost classification implemented in fiscal year 2010.

For fiscal year 2010, $134.3 million of SE costs are included in sales and marketing expenses. For comparative purposes, had the reclassification been affected for fiscal years 2009 and 2008, the pro forma cost of revenues for each of the Company’s reportable segment and sales and marketing expenses would have been as follows (in thousands):

	Pro Forma Amount
	Fiscal Year Ended October  31, 2009		Fiscal Year Ended October  25, 2008
Cost of revenues
Data Storage	$	408,026	$	393,283
Ethernet Products		228,908		10,133
Global Services		161,946		141,382
Total cost of revenues		798,880		544,798
Sales and marketing expenses	$	505,701	$	336,078

2. Summary of Significant Accounting Policies

Cash and Cash Equivalents

The Company considers all highly liquid investments with an original or remaining maturity of three months or less at the date of purchase to be cash equivalents.

Restricted Cash

During fiscal year 2009, the Company entered into an agreement with one of the defendants in connection with the Special Litigation Committee’s litigation. Under this agreement, the Company received $12.5 million, which was held in restricted cash pending settlement of certain contingencies. On February 3, 2010, these contingencies were satisfied and the restrictions on the cash were removed.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Investments and Equity Securities

Investment securities with an original maturity of more than three months that mature less than one year from the Consolidated Balance Sheet date are considered short-term investments. Investment securities with an original or remaining maturity of one year or more and which the Company has the ability and intent to hold are considered long-term investments. Investments are classified as available-for-sale and are recorded on the accompanying Consolidated Balance Sheets at fair value.

Equity securities are classified as available-for-sale when there are no restrictions on the Company’s ability to immediately liquidate such securities. Marketable equity securities are recorded at fair value.

Unrealized holding gains and losses related to the Company’s investments and equity securities are included as a separate component of accumulated other comprehensive loss on the accompanying Consolidated Balance Sheets, net of any related tax effect. Realized gains and losses are calculated based on the specific identification method and are included in “Other income (loss), net,” on the Consolidated Statements of Operations.

The Company recognizes an impairment charge when the declines in the fair values of its investments and equity securities below the cost basis are assessed to be other-than-temporary. An other-than-temporary impairment is triggered when there is an intent to sell the security, it is more likely than not that the security will be required to be sold before recovery, or the security is not expected to recover the entire amortized cost basis of the security. The Company also considers various factors in determining whether to recognize an impairment charge, including the length of time and extent to which the fair value has been less than the cost basis and the financial condition and near-term prospects of the investee. For impairments involving credit losses, the Company recognizes the credit loss component in earnings and the remainder of the impairment is recorded in accumulated other comprehensive loss.

From time to time the Company makes equity investments in non-publicly traded companies. These investments are included in “Other assets” on the accompanying Consolidated Balance Sheets and are generally accounted for under the cost method as the Company does not have the ability to exercise significant influence over the respective investee’s operating and financial policies nor does it have a liquidation preference that is substantive. The Company monitors its investments in non-publicly traded companies for impairment on a quarterly basis and makes appropriate reductions in carrying values when such impairments are determined to be other-than-temporary. Impairment charges are included in “Other income (loss), net,” on the Consolidated Statements of Operations. Factors considered in determining an impairment include, but are not limited to, the current business environment including competition and uncertainty of financial condition, going concern considerations such as the rate at which the investee company utilizes cash and the investee company’s ability to obtain additional private financing to fulfill its stated business plan, the need for changes to the investee company’s existing business model due to changing business environments and its ability to successfully implement necessary changes, and comparable valuations. If an investment is determined to be impaired, a determination is made as to whether such impairment is other-than-temporary.

Fair Value of Financial Instruments

The fair value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, restricted cash, accounts payable and accrued liabilities, approximate cost because of their short maturities. The fair value of the Company’s investments is primarily determined using quoted market prices for those securities or similar financial instruments.

Convertible Debt Instruments

In the first fiscal quarter of 2010, the Company adopted a new standard issued by the Financial Accounting Standards Board (“FASB”) that changed the accounting for convertible debt instruments with cash settlement features. As of adoption, this new accounting standard applied to the Company’s convertible subordinated debt. Under the previous accounting standard, the convertible subordinated debt was recognized entirely as a liability. In accordance with adopting this new accounting standard, Brocade retrospectively recognized both a liability and an equity component of the convertible subordinated debt at fair value. The liability component is recognized as the fair value of a similar instrument that does not have a conversion feature at issuance. The equity component, which is the value of the conversion feature at issuance, is recognized as the difference between the proceeds from the issuance of the convertible subordinated debt and the fair value of the liability component, after adjusting for the deferred tax impact. The convertible subordinated debt was issued at a coupon rate of 2.25%, which was below that of a comparable instrument that does not have a conversion feature (8.75%). Therefore, the valuation of the debt component, using the income approach, resulted in a debt discount. The debt discount is reduced over the expected life of the debt, which is also the stated life of the debt. For additional discussion, see Note 9, “Borrowings,” of the Notes to Consolidated Financial Statements.

As a result of applying this new accounting standard retrospectively to all periods presented, the Company recognized the following incremental effects on individual line items on the Consolidated Statements of Operations (in thousands, except per share amounts):

	Fiscal Year Ended October 31, 2009
	Before Adoption			Adjustments			After Adoption
Interest expense	$	(91,281	)	$	(8,013	)	$	(99,294	)

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Derivative Financial Instruments

In the normal course of business, the Company is exposed to fluctuations in interest rates and the exchange rates associated with foreign currencies. The derivatives entered into by the Company qualify for and are designated as foreign currency cash flow hedges.

The derivatives are recognized on the Consolidated Balance Sheets at their respective fair values. Changes in fair values of outstanding cash flow hedges that are highly effective are recorded in accumulated other comprehensive loss until earnings are affected by the variability of cash flows of the underlying hedged transaction. In most cases, amounts recorded in accumulated other comprehensive loss will be released to earnings at maturity of the related derivative. The recognition of effective hedge results offsets the gains or losses on the underlying exposure. Cash flows from derivative transactions are classified according to the nature of the risk being hedged.

The Company formally documents all relationships between hedging instruments and hedged items, as well as the risk-management objective and strategy for undertaking hedge transactions. This documentation includes linking all derivatives either to specific assets and liabilities on the consolidated balance sheets or specific firm commitments or forecasted transactions. The Company also formally assesses both at the hedge’s inception and on an ongoing basis whether the derivatives used in hedging transactions have been highly effective in offsetting changes in the cash flows of hedged items and whether those derivatives may be expected to remain highly effective in future periods. When it is determined that a derivative is not, or has ceased to be, highly effective as a hedge, the Company discontinues hedge accounting prospectively, as discussed below.

The Company discontinues hedge accounting prospectively when (i) the derivative is no longer highly effective in offsetting changes in the cash flows of a hedged item (including hedged items such as firm commitments or forecasted transactions); (ii) the derivative expires or is sold, terminated or exercised; (iii) it is no longer probable that the forecasted transaction will occur; or (iv) management determines that designating the derivative as a hedging instrument is no longer appropriate.

When the Company discontinues hedge accounting, but it continues to be probable that the forecasted transaction will occur in the originally expected period, the gain or loss on the derivative remains in accumulated other comprehensive loss and is reclassified into earnings when the forecasted transaction affects earnings. However, if it is no longer probable that a forecasted transaction will occur by the end of the originally specified time period or within an additional two-month period of time thereafter, the gain or loss that was in accumulated other comprehensive loss will be recognized immediately in earnings. In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company will carry the derivative at its fair value on the Consolidated Balance Sheet until maturity and will recognize future changes in the fair value in current period earnings. Any hedge ineffectiveness is recorded in current period earnings within “Other income (loss), net.” Effectiveness is assessed based on the comparison of current forward rates to the rates established on the Company’s hedges.

Inventories

Inventories are stated at the lower of cost or market, using the first-in, first-out method. Inventory costs include material, labor and overhead. The Company records inventory write-downs based on excess and obsolete inventory determined primarily by future demand forecast. A portion of the Company’s inventory is located offsite at customers’ hubs, service depots and at contract manufacturers’ locations. Cash flows related to the sale of inventories are classified as cash flows from operating activities.

71

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation and amortization. Depreciation is computed using the straight-line method over the estimated useful lives of the assets. An estimated useful life of 4 years is used for computer equipment and software, except for the Company’s enterprise-wide, integrated business information system which is depreciated over 5 to 7 years. Effective May 1, 2010, the Company prospectively changed the estimated useful life of its furniture from 4 years to 7 years for furniture placed in service on or after that date, including furniture on capital lease. The Company will continue to use the straight-line method to depreciate furniture. The change in useful life was adopted because the life of the new furniture is estimated to be longer than previously purchased furniture. Furniture placed in service prior to May 1, 2010 will continue to be depreciated over 4 years using the straight-line method. Estimated useful lives of up to 4 years are used for engineering and other equipment and an estimated useful life of 30 years is used for buildings. Leasehold improvements are amortized using the straight-line method over the shorter of the useful life of the asset or the remaining term of the lease.

Brocade evaluates long-lived assets, such as property and equipment, for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable in accordance with ASC 360-10 Property, Plant and Equipment. Brocade assesses the fair value of the assets based on the undiscounted future cash flow the assets are expected to generate and recognizes an impairment loss when estimated undiscounted future cash flow expected to result from the use of the asset plus net proceeds expected to result from the disposition of the asset, if any, are less than the carrying value of the asset. When Brocade identifies an impairment, Brocade reduces the carrying amount of the asset to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values.

Goodwill and Intangible Assets

The Company capitalizes goodwill at cost and evaluates goodwill on an annual basis during its second fiscal quarter or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss is recognized to the extent that the carrying amount of goodwill exceeds the asset’s implied fair value. Events which might indicate impairment include, but are not limited to, strategic decisions made in response to economic and competitive conditions, the impact of the economic environment on the Company’s customer base, material negative changes in relationships with significant customers, and/or a significant decline in the Company’s stock price for a sustained period.

Intangible assets are carried at cost less accumulated amortization. Amortization is recognized over the estimated useful life of the respective asset. The Company evaluates intangible assets for impairment whenever events or changes in circumstances indicate that the carrying value of such assets may not be recoverable. Examples of such events or circumstances include, but are not limited to, significant underperformance relative to historical or projected future operating results, significant changes in the manner of use of acquired assets or the strategy for the Company’s business, significant negative industry or economic trends, and/or a significant decline in the Company’s stock price for a sustained period. Impairment is recognized based on the difference between the fair value of the asset and its carrying value, and fair value is generally measured based on discounted cash flow analyses. For additional discussion, see Note 4, “Goodwill and Intangible Assets,” of the Notes to Consolidated Financial Statements.

Trade Receivables Factoring Facility

During April 2010, the Company entered into a trade receivables factoring facility with a financial institution to sell certain of its trade receivables from customers with limited, non-credit related, recourse provisions. The sale of receivables eliminates the credit exposure of the Company in relation to these receivables.

72

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company pays facility administration fees to the financial institution on a quarterly basis. Under the terms of the factoring agreement, the maximum available amount of the factoring facility outstanding at any one time is $50.0 million, which is subject to change based on the financial institution’s approval. During the fiscal year ended October 30, 2010, $61.4 million of trade receivables were sold under the terms of the factoring facility. Sales of trade receivables are recorded as a reduction of trade accounts receivable. The losses resulting from the discount on the sale of receivables for the fiscal year ended October 30, 2010 were immaterial and are included in “Other income (loss), net” on the Consolidated Statement of Operations. Facility administration fees for the fiscal year ended October 30, 2010 were immaterial and are included in “General and administrative expenses” on the Consolidated Statements of Operations.

Litigation Costs

The Company is subject to the possibility of legal actions arising in the ordinary course of business. The Company regularly monitors the status of pending legal actions to evaluate both the magnitude and likelihood of any potential losses. An accrual for these potential losses is made when they are probable and the amount of loss, or possible range of loss, can be reasonably estimated. In addition, recoveries are shown as a reduction in litigation costs in the period in which they are realized.

Concentrations

Financial instruments that potentially subject the Company to concentrations of credit risk consist primarily of cash, cash equivalents, short-term investments and accounts receivable. Cash, cash equivalents and short-term investments are primarily maintained at five major financial institutions in the United States. Deposits held with banks may be redeemed upon demand and may exceed the amount of insurance provided on such deposits.

A majority of the Company’s accounts receivable balance is derived from sales to OEM partners in the computer storage and server industry. As of October 30, 2010, three customers accounted for 17%, 14% and 10%, respectively, of total accounts receivable. As of October 31, 2009, two customers accounted for 16% and 11%, respectively, of total accounts receivable. The Company performs ongoing credit evaluations of its customers and generally does not require collateral on accounts receivable balances. The Company has established reserves for credit losses, sales allowances, and other allowances.

For the years ended October 30, 2010, October 31, 2009 and October 25, 2008, the same three customers each represented 10% or more of our total net revenues for a combined total of 47% (EMC with 16%, HP with 14% and IBM with 17%), 48% (EMC with 18%, HP with 13% and IBM with 17%) and 65% (EMC with 25%, HP with 18% and IBM with 22%), respectively.

The Company currently relies on single and limited sources for multiple key components used in the manufacture of its products. Additionally, the Company relies on multiple contract manufacturers for the production of its products, including Hon Hai Precision Industry Co., Ltd., Sanmina-SCI Corporation, Asteel Flash Group, Accton Wireless Broadband Corporation, Motorola, Inc. and Quanta Computer Incorporated (collectively the “CMs”). Although the Company uses standard parts and components for its products where possible, the Company’s CMs currently purchase, on their behalf, several key components used in the manufacture of products from single or limited supplier sources.

Revenue Recognition

Product revenue. Substantially all of the Company’s products are integrated with software that is essential to the functionality of the equipment. Additionally, the Company provides unspecified software upgrades and

73

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

enhancements related to the equipment through its maintenance contracts for most of its products. Product revenue is generally recognized when all of the following criteria have been met:

• Persuasive evidence of an arrangement exists;

• Delivery has occurred;

• The fee is fixed or determinable; and

• Collectability is reasonably assured or collection is probable.

For newly introduced products, many of the Company’s large OEM customers require a product qualification period during which the Company’s products are tested and approved by the OEM customers for sale to their customers. Revenue recognition and related cost are deferred for shipments to new OEM customers and for shipments of newly introduced products to existing OEM customers until satisfactory evidence of completion of the product qualification has been received from the OEM customer. In addition, revenue from sales to the Company’s distributor customers is recognized in the same period in which the product is actually sold by the distributor (sell-through).

The Company reduces revenue for estimated sales allowances at the time of shipment and sales programs at the later of revenue recognition or communication of the commitment for sales incentives. Sales allowances are estimated based on historical sales returns. Sales programs are estimated based on approved sales programs versus claims under such sales programs, current trends and the Company’s expectations regarding future activity. In addition, the Company maintains an allowance for doubtful accounts, which is also accounted for as a reduction in revenue. The Company establishes the allowance for doubtful accounts to ensure accounts receivables are not overstated due to uncollectability. The Company maintains bad debt reserves based upon the analysis of accounts receivable, historical collection patterns, customer concentrations, customer creditworthiness, current economic trends, changes in customer payment terms and practices, and customer communication. The Company records a specific reserve for individual accounts when it becomes aware of a customer’s likely inability to meet its financial obligations, such as in the case of bankruptcy filings or deterioration in the customer’s operating results or financial position. If circumstances related to customers change, the Company would further adjust estimates of the recoverability of receivables.

In October 2009, the FASB amended the accounting standards for revenue recognition to remove tangible products containing software components and non-software components that function together to deliver the products’ essential functionality from the scope of industry-specific software revenue recognition guidance. In October 2009, the FASB also amended the accounting standards for multiple deliverable revenue arrangements to:

• provide updated guidance on whether multiple deliverables exist, how the deliverables in an arrangement should be separated, and how the consideration should be allocated;

• require an entity to allocate revenue in an arrangement using estimated selling price (“ESP”) of deliverables if a vendor does not have vendor-specific objective evidence (“VSOE”) of selling price or third-party evidence (“TPE”) of selling price; and

• eliminate the use of the residual method and require an entity to allocate revenue using the relative selling price method.

The Company elected to early adopt this accounting guidance at the beginning of its first quarter of fiscal year 2010 on a prospective basis for applicable transactions originating or materially modified after October 31, 2009.

74

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Multiple-element arrangements. The Company’s multiple-element product offerings include networking hardware with embedded software products and support, which are considered separate units of accounting. For certain of the Company’s products, software and non-software components function together to deliver the tangible products’ essential functionality.

For transactions entered into prior to the first quarter of fiscal year 2010, the Company allocated revenue to each element in a multiple-element arrangement based upon VSOE of the fair value of the element, or if VSOE was not available for the delivered element, by application of the residual method. In the application of the residual method, the Company allocated revenue to the undelivered elements based on VSOE of fair value for those elements and allocated the residual revenue to the delivered elements. VSOE of the fair value for an element was based upon the price charged when the element was sold separately. Revenue allocated to each element was then recognized when the basic revenue recognition criteria was met for each element. For sales of products that contained multiple elements and where software was incidental, the Company determined the separate units of accounting that existed within the arrangement. If more than one unit of accounting existed, the arrangement consideration was allocated to each unit of accounting using the residual fair value method. Revenue was recognized for each unit of accounting when all the revenue recognition criteria had been met for that unit of accounting.

Under the new accounting guidance, the Company allocates revenue to each element in a multiple-element arrangement based upon their relative selling price. When applying the relative selling price method, the Company determines the selling price for each deliverable using VSOE of selling price, if it exists, or TPE of selling price. If neither VSOE nor TPE of selling price exist for a deliverable, the Company uses its best estimate of selling price for that deliverable. Revenue allocated to each element is then recognized when the basic revenue recognition criteria are met for each element.

Consistent with its methodology under previous accounting guidance, the Company determines VSOE based on its normal pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, the Company requires that a substantial majority of the selling prices for a product or service fall within a reasonably narrow pricing range, generally evidenced by approximately 80% of such historical stand-alone transactions falling within ±15% of the median rates. For post-contract customer support (“PCS”), however, the Company considers stated renewal rates in determining VSOE.

In most instances, the Company is not able to establish VSOE for all deliverables in an arrangement with multiple elements. This may be due to the Company infrequently selling each element separately, not pricing products within a narrow range, or only having a limited sales history. When VSOE cannot be established, the Company attempts to establish selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. Generally, the Company’s go-to-market strategy differs from that of its peers and its offerings contain a significant level of customization and differentiation such that the comparable pricing of products with similar functionality cannot be obtained. Furthermore, the Company is unable to reliably determine what similar competitor products’ selling prices are on a stand-alone basis. Therefore, the Company is typically not able to determine TPE.

When the Company is unable to establish selling price using VSOE or TPE, the Company uses ESP in its allocation of the arrangement consideration. The objective of ESP is to determine the price at which the Company would transact a sale if the product or service were sold on a stand-alone basis. ESP is generally used for offerings that are not typically sold on a stand-alone basis or for new or highly customized offerings.

The Company determines ESP for a product or service by considering multiple factors including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives and

pricing practices. The determination of ESP is made through consultation with and formal approval by the Company’s management, taking into consideration the go-to-market strategy.

The Company regularly reviews VSOE, TPE and ESP and maintains internal controls over the establishment and updates of these estimates. There was no material impact on revenues during the fiscal year ended October 30, 2010 nor does the Company expect a material impact in the near term from changes in VSOE, TPE or ESP.

The following table shows total net revenues as reported and unaudited pro forma total net revenues that would have been reported during the fiscal year ended October 30, 2010 if the transactions entered into or materially modified after October 31, 2009 were subject to previous accounting guidance:

	As Reported		Pro Forma Basis as  if the Previous Accounting Guidance Was in Effect
	In thousands
Total net revenues for the twelve months ended October 30, 2010	$	2,094,363	$	2,084,353

The impact to total net revenues during the fiscal year ended October 30, 2010 of the accounting guidance was primarily to net product revenues. Since the use of the residual method is eliminated under the new accounting standards, any discounts offered by the Company are allocated to all deliverables, rather than only products delivered upfront.

The new accounting standards for revenue recognition if applied in the same manner to the year ended October 31, 2009 would not have had a material impact on total net revenues for that fiscal year. In terms of the timing and pattern of revenue recognition, the new accounting guidance for revenue recognition is not expected to have a significant effect on total net revenues in periods after the initial adoption when applied to multiple-element arrangements based on current go-to-market strategies due to the existence of VSOE on PCS and consistent ESP across most of our product offerings.

Services revenue. Services revenue consists of training and maintenance arrangements, including PCS, separately priced extended warranties and other professional services. PCS services are offered under renewable, annual fee-based contracts or as part of multiple-element arrangements, and typically include telephone support and upgrades and enhancements to the Company’s operating system software. Revenue related to PCS elements is deferred and recognized ratably over the contractual period. PCS contracts are typically one to three years in length.

Professional services are offered under hourly or fixed fee-based contracts or as part of multiple-element arrangements. Professional services revenue is recognized as services are performed. Training revenue is recognized upon completion of the training.

Warranty Expense

The Company provides standard warranties on its products ranging from one year to limited lifetime warranties. Estimated future warranty costs are accrued at the time of shipment and charged to cost of revenues based upon historical experience, current trends and the Company’s expectations regarding future experience.

Foreign Currency

Assets and liabilities of the Company’s international subsidiaries in which the local currency is the functional currency are translated into U.S. dollars at period-end exchange rates. Income and expenses are

76

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

translated into U.S. dollars at the average exchange rates during the period. The resulting translation adjustments are included in the Company’s Consolidated Balance Sheets in the stockholders’ equity section as a component of accumulated other comprehensive loss. Foreign exchange gains and losses for assets and liabilities of the Company’s international subsidiaries in which the local currency is the U.S. dollar are recorded in the Company’s Consolidated Statement of Operations.

Software Development Costs

Eligible software development costs are capitalized upon the establishment of technological feasibility, which is defined as being equivalent to completion of a beta-phase working prototype. Total eligible software development costs have not been material to date.

Costs related to internally developed software and software purchased for internal use are capitalized. As of October 30, 2010 and October 31, 2009 a net book value of $3.7 million and $5.4 million, respectively, related to the purchase and subsequent implementation and upgrade of the Company’s enterprise wide integrated business information system was included in “Property and equipment, net.” These costs are being depreciated over the estimated useful lives of five to seven years.

Advertising Costs

The Company expenses all advertising costs as incurred. Advertising costs were $7.9 million, $5.9 million and $8.4 million for the years ended October 30, 2010, October 31, 2009 and October 25, 2008, respectively.

Capitalized Interest Costs

Interest costs related to major construction projects, specifically the Company campus project, are capitalized until the asset is ready for service. Capitalized interest is calculated by multiplying the weighted-average interest rate on the Senior Secured Credit Facility, Senior Secured Notes and convertible debt by the qualifying costs. Interest capitalized may not exceed gross interest expense for the period. As the qualifying asset is moved to the depreciation and amortization pool, the related capitalized interest is also transferred and is amortized over the useful life of the related asset. Interest costs of $7.8 million, $9.1 million and $1.0 million were capitalized for the years ended October 30, 2010, October 31, 2009 and October 25, 2008, respectively. Construction of the Company campus was completed in the third quarter of fiscal year 2010.

Income Taxes

The Company accounts for income taxes under the assets and liabilities method. Under this method, the Company recognizes income tax expense for the amount of taxes payable or refundable for the current year. Deferred tax assets and liabilities are recognized for the expected tax consequences of temporary differences between the tax bases of assets and liabilities and their reported amounts, along with net operating loss carry forwards and credit carry forwards. A valuation allowance is recognized to the extent that it is more likely than not that the tax benefits will not be realized. For additional discussion, see Note 15, “Income Taxes,” of the Notes to Consolidated Financial Statements.

The Company adopted the provisions of ASC 740-10 Income Taxes (“ASC 740-10”), effective at the beginning of fiscal year 2008. ASC 740-10 prescribes a recognition threshold and measurement attribute for financial statement purposes of tax positions taken or expected to be taken on a tax return. Recognition of a tax position is determined when it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. Upon its adoption of ASC 740-10, the Company

77

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

applied the provisions of ASC 740-10 to all income tax positions. The cumulative effect of applying the provisions of ASC 740-10 in the amount of $3.1 million has been reported as an adjustment to the opening balance of accumulated deficit on the Company’s Consolidated Balance Sheet as of the beginning of fiscal year 2008.

Computation of Net Income (Loss) per Share

Basic net income (loss) per share is computed using the weighted-average number of common shares outstanding during the period, less shares subject to repurchase. Diluted net income per share is computed using the weighted-average number of common shares outstanding and potentially dilutive common shares outstanding during the period that have a dilutive effect on earnings per share. Potentially dilutive common shares result from the assumed exercise of outstanding stock options, assumed vesting of outstanding restricted stock units and awards, assumed issuance of stock under the employee stock purchase plan using the treasury stock method, and the assumed conversion of outstanding convertible subordinated debt using the if-converted method. In a net loss position, diluted net loss per share is computed using only the weighted-average number of common shares outstanding during the period, less shares subject to repurchase, as any additional common shares would be antidilutive.

Stock-Based Compensation

The Company accounts for employee equity awards under the fair value method. Accordingly, the Company measures stock-based compensation at the grant date based on the fair value of the award. The fair value of stock options and the Employee Stock Purchase Plan (“ESPP”) is estimated using the Black-Scholes option pricing model. Estimated compensation cost relating to restricted stock units is based on the fair value of the Company’s common stock on the date of the grant. The Company records stock-based compensation expense over the twenty-four month offering period in connection with shares issued under its ESPP. The compensation expense for stock-based awards is reduced by an estimate for forfeitures and is recognized over the expected term of the award under a graded vesting method. For additional discussion, see Note 14, “Stock-Based Compensation,” of the Notes to Consolidated Financial Statements.

The Company accounts for the tax effects of share-based payment awards using the alternative transition method, which includes simplified methods to establish the beginning balance of the additional paid-in capital pool (“APIC Pool”) related to the tax effects of employee stock-based compensation and to determine the subsequent impact on the APIC Pool and consolidated statement of cash flows of the tax effects of employee stock-based compensation awards.

Use of Estimates in Preparation of Consolidated Financial Statements

The preparation of consolidated financial statements and related disclosures in conformity with U.S. generally accepted accounting principles requires management to make estimates and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. Estimates are used for, but not limited to sales allowances and programs, allowance for doubtful account, stock-based compensation, purchase price allocations, warranty obligations, inventory valuation and purchase commitments, restructuring costs, facilities lease losses, impairment of goodwill and intangible assets, litigation, income taxes and investments. Actual results may differ materially from these estimates.

Recent Accounting Pronouncements

In January 2010, the FASB issued an update to ASC 820-10 Measuring Liabilities at Fair Values (“ASC 820-10”). The update to ASC 820-10 requires disclosure of significant transfers in and out of Level 1 and Level 2 measurements and the reasons for the transfers, and a gross presentation of activity within the Level 3

78

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

rollforward, presenting separately information about purchases, sales issuances and settlements. The update to ASC 820-10 was adopted by the Company in the second quarter of fiscal year 2010, except for the gross presentation of the Level 3 rollforward which will be adopted by the Company in the second quarter of fiscal year 2011. The Company does not expect the adoption of the update to ASC 820-10 to have a material impact on its financial position, results of operations, or cash flows.

In April 2010, the FASB issued an update to ASC 718 Compensation—Stock Compensation (“ASC 718”). The update to ASC 718 clarifies that a share-based payment award with an exercise price denominated in the currency of a market in which a substantial portion of the Company’s equity securities trades should not be considered to contain a condition that is not a market, performance, or service condition. Therefore, such an award should not be classified as a liability if it otherwise qualifies as equity. The update to ASC 718 will be adopted by the Company in the first quarter of fiscal year 2012, with earlier adoption permitted. The Company is currently evaluating the impact of the update to ASC 718, but does not expect the adoption to have a material impact on its financial position, results of operations, or cash flows.

3. Acquisitions

Foundry Networks, Inc.

On December 18, 2008, the Company completed its acquisition of Foundry Networks, Inc. (“Foundry”) in accordance with the Agreement and Plan of Merger, which the Company entered into on July 21, 2008, as well as with Amendment No. 1 to the Agreement and Plan of Merger, which the Company entered into on November 7, 2008 (as amended, the “Foundry Merger Agreement”). As a result of the merger, Foundry is now a wholly-owned subsidiary of the Company and was converted to a limited liability company under applicable Delaware law in the third fiscal quarter of 2009.

The Company recorded the acquisition using the purchase method of accounting and, accordingly, has included the results of operations of Foundry in the accompanying Consolidated Statements of Operations from December 18, 2008, the date the acquisition was completed.

The total purchase price of the Foundry acquisition was $2.8 billion and is comprised of the following (in thousands):

	Amount (in  thousands)
Cash tendered for shares of outstanding common stock of Foundry (1)	$	2,506,474
Fair value of stock options and awards assumed and accelerated in connection with acquisition		254,312
Direct transaction costs		27,395
Total purchase price	$	2,788,181

(1) This amount includes $248.4 million paid by the Company to acquire 14.0 million shares of Foundry common stock in the open market before the consummation of the acquisition, net of $3.5 million in dividends received.

Direct transaction costs include investment banking, legal and accounting fees and other external costs directly related to the acquisition.

The Company allocated the total purchase consideration to the net assets acquired and liabilities assumed, including identifiable intangible assets, based on their respective fair values at the acquisition date, resulting in initial goodwill of approximately $1,475.6 million, which is not deductible for income tax purposes. Goodwill

79

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

represents the excess of the purchase price over the fair value of the underlying acquired net tangible and intangible assets. The factors that contributed to the recognition of goodwill included securing buyer-specific synergies that increase revenue and profits and are not otherwise available to a marketplace participant, acquiring a talented workforce, and significant cost-saving opportunities. The allocation of the purchase price reflects various estimates and analyses.

The Company also allocated $26.9 million to in-process research and development (“IPR&D”) which was charged to operating expense at the consummation of the business combination. The value assigned to the Foundry IPR&D was determined by estimating costs to develop the purchased IPR&D into commercially viable products, estimating the resulting net cash flows from the projects when completed, and discounting the net cash flows to their present values. The revenue estimates used in the net cash flow forecasts were based on estimates of relevant market sizes and growth factors, expected trends in technology, and the nature and expected timing of new product introductions by Foundry and its competitors.

The rate utilized to discount the net cash flows to their present values was based on Foundry’s weighted-average cost of capital. The weighted-average cost of capital was adjusted to reflect the difficulties and uncertainties in completing each project and thereby achieving technological feasibility, the percentage of completion of each project, anticipated market acceptance and penetration, market growth rates, and risks related to the impact of potential changes in future target markets. Based on these factors, a discount rate of 12.5% was deemed appropriate for valuing the IPR&D. The estimates used in valuing IPR&D were based upon assumptions believed to be reasonable but which are inherently uncertain and unpredictable.

Of the total purchase price, approximately $392.3 million has been allocated to amortizable intangible assets acquired. The amortizable intangible assets are being amortized on a straight-line basis over their estimated useful lives as follows:

	Amount (in  thousands)		Weighted- Average Useful Life (in years)
Developed products technology	$	191,300		5.00
Customer relationships	$	194,500		5.00
Order backlog	$	6,500		0.25

The following unaudited pro forma financial information for the twelve months ended October 30, 2009 and October 25, 2008 presents a summary of the results of operations of the Company assuming the acquisition of Foundry occurred at the beginning of the period presented. The unaudited pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the merger had taken place at the beginning of each of the periods presented, nor is it indicative of future operating results (in thousands, except per share amounts):

	Twelve Months Ended			Twelve Months Ended
	October 31, 2009 (1)  (3)			October 25, 2008 (2)  (3)
Total net revenues	$	2,029,973		$	2,112,229

to December 18, 2008, and Foundry’s historical results for the period October 26, 2008 to December 18, 2008, including goodwill and acquisition-related intangible assets impairment of $53.3 million, amortization for acquired intangible assets, elimination of IPR&D charge and acquisition-related fees, and related tax effects.

(2) The unaudited pro forma financial results for the twelve months ended October 25, 2008 include Brocade’s historical results for the twelve months ended October 25, 2008 and Foundry’s historical results for the three months ended December 31, 2007 and nine months ended September 30, 2008, including provision for class action lawsuit of $160.0 million, release of the valuation allowance of $174.4 million, amortization for acquired intangible assets, adjustment to interest expense, and related tax effects.

(3) Brocade’s historical results for the twelve months ended October 31, 2009 and October 25, 2008 reflect the incremental effects on individual line items on the Consolidated Statement of Operation as a result of retrospectively applying the new accounting standard for convertible debt instruments (see Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements).

Strategic Business Systems, Inc.

On March 17, 2008, the Company completed its acquisition of Strategic Business Systems, Inc. (“SBS”), a privately held provider of IT professional services for medium-size and large enterprises in both the commercial and federal government sectors. This acquisition expanded the Company’s professional service offerings and was consistent with its goal of building an end-to-end services portfolio.

The results of operations of SBS are included in the accompanying Consolidated Statements of Operations from the date of the acquisition. The Company does not consider the acquisition of SBS to be material to its results of operations and is therefore not presenting pro forma financial information of operations.

4. Goodwill and Intangible Assets

(1) As adjusted due to adoption of update to ASC 470-20 relating to accounting for convertible debt instruments. See Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements.

(2) During the second quarter of fiscal year 2009, the Company made a decision to no longer offer its suite of Files products and concluded that the fair value of the Files reporting unit was less than its carrying amount. The fair value of the Files business was determined using comparable companies’ data. The Company conducted the second step of the goodwill impairment test and determined that all of the Files goodwill was impaired. Accordingly, the Company recorded a goodwill impairment charge of $45.8 million for the three months ended May 2, 2009.

(3) The goodwill adjustment of $39.8 million was primarily a result of the realization of deferred tax assets and tax benefit of stock options exercised from acquired companies and includes $1.7 million of Foundry purchase accounting adjustments, and the adjustment resulting from the adoption of a new accounting standard for its convertible debt from acquired companies. See Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements.

(4) The goodwill adjustment of $15.0 million was primarily a result of realization of deferred tax assets and tax benefit of stock options exercised from acquired companies, partially offset by the impact of adoption of the new accounting standard for its convertible debt from acquired companies.

The Company conducts its goodwill impairment test annually, as of the first day of the second fiscal quarter, or whenever events or changes in facts and circumstances indicate that the fair value of the reporting unit may be less than its carrying amount. For the fiscal year 2010 annual goodwill impairment test, the Company used the income approach, the market approach, or a combination thereof, to determine each reporting unit’s fair value. The income approach provides an estimate of fair value based on discounted expected future cash flows. The market approach provides an estimate of fair value using various price or market multiples applied to the reporting unit’s operating results and then applying an appropriate control premium. During the fiscal year 2010 annual goodwill impairment test under the first step, the Company used a combination of approaches to estimate each reporting unit’s fair value, but relied primarily on the income approach results, using management’s recent, post-recession cash flow projections for each reporting unit and risk-adjusted discount rates. The Company believes that the income approach is more representative of a reporting unit’s fair value compared to market approach results due to conditions of current financial markets and other market factors.

Determining the fair value of a reporting unit or an intangible asset requires judgment and involves the use of significant estimates and assumptions. The Company based its fair value estimates on assumptions it believes to be reasonable, but that are unpredictable and inherently uncertain. Estimates and assumptions with respect to the determination of the fair value of its reporting units using the income approach include, among other inputs:

• The Company’s operating forecasts;

• Revenue growth rates; and

• Risk-commensurate discount rates and costs of capital.

The Company’s estimates of revenues and costs are based on historical data, various internal estimates and a variety of external sources, and are developed as part of our regular long-range planning process. The control premium used in market or combined approaches is determined by considering control premiums offered as part of the acquisitions that have occurred in the reporting units’ comparable market segments. Based on goodwill impairment analysis results during the second fiscal quarter of 2010, the Company determined that no impairment needed to be recorded. During the fiscal year ended October 30, 2010, there were no facts and circumstances that indicated that the fair value of the reporting units may be less than their current carrying amount.

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company records impairment losses on long-lived assets used in operations when indications of impairment are present and the undiscounted cash flows estimated to be generated by those assets are less than the assets’ carrying amounts. If such assets are considered to be impaired, the impairment charge recognized is the amount by which the carrying amount of the assets exceeds the fair value of the assets. As a result of the impairment of the Files reporting unit in fiscal year 2009, the Company performed an impairment analysis for long-lived Files assets, including its intangible assets. The analysis indicated that all of the intangible assets associated with the Files business were not recoverable. As a result, the Company recorded an acquisition-related intangible assets impairment charge associated with the Files business of $7.5 million during the second quarter of fiscal year 2009.

Intangible assets other than goodwill are amortized over the following estimated remaining useful lives, unless the Company has determined these lives to be indefinite. The following tables present details of the Company’s intangible assets (in thousands, except for weighted-average remaining useful life):

(1) Depreciation expense was approximately $72.8 million, $59.9 million and $49.8 million for the years ended October 30, 2010, October 31, 2009 and October 25, 2008, respectively.

(2) Effective May 1, 2010, the Company prospectively changed the estimated useful life of its furniture from 4 years to 7 years for furniture placed in service on or after that date. The Company will continue to use the straight-line method to depreciate furniture. The change in useful life was adopted because the life of the new furniture is estimated to be longer than previously purchased furniture. The impact to the Company’s results of operations during the fiscal year ended October 30, 2010 was not material. Furniture placed in service prior to May 1, 2010 will continue to be depreciated over 4 years using the straight-line method and have a net book value of $3.0 million as of October 30, 2010. In addition, furniture and fixtures include the following amounts under leases as of October 30, 2010 and October 31, 2009:

8. Fair Value Measurements

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and it considers assumptions that market participants would use when pricing the asset or liability. The Company applies fair value measurements for both financial and nonfinancial assets and liabilities. The Company has no nonfinancial assets and liabilities that are required to be measured at fair value on a recurring basis as of October 30, 2010.

In the first fiscal quarter of 2010, the Company adopted provisions of ASC 820 for the Company’s nonfinancial assets and nonfinancial liabilities that are measured at fair value on a nonrecurring basis in periods subsequent to initial recognition. ASC 820 specifies, on a prospective basis, the way in which fair value measurements should be made for these assets and liabilities and additional disclosures related to the measurements. There were no fair value measurements recorded for such assets and liabilities during fiscal year 2010 since adoption.

The fair value of the Company’s financial instruments, including cash and cash equivalents, accounts receivable, restricted cash, accounts payable and accrued liabilities, approximate cost because of their short maturities.

In the second fiscal quarter of 2010, the Company adopted the update to ASC 820-10, which requires disclosure of significant transfers in and out of Level 1 and Level 2 measurements and the reasons for the transfers. There were no transfers of this nature during fiscal year ended October 30, 2010.

The Company did not elect to measure any eligible financial instruments at fair value and report unrealized gains and losses on items for which the fair value option has been elected in earnings at each subsequent reporting date.

Fair Value Hierarchy

The Company utilizes a fair value hierarchy that maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. There are three levels of inputs that may be used to measure fair value:

Level 1

Observable inputs that reflect quoted prices in active markets for identical assets or liabilities. Brocade’s assets utilizing Level 1 inputs include money market funds.

Level 2

Inputs that reflect quoted prices for similar assets or liabilities in active markets, quoted prices for identical assets or liabilities in less active markets, or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data. Brocade’s assets and liabilities utilizing Level 2 inputs include corporate bonds and derivative instruments, respectively.

Level 3

Unobservable inputs that reflect the Company’s own assumptions incorporated in valuation techniques used to determine fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available. Brocade has no assets or liabilities utilizing Level 3 inputs.

Assets and liabilities measured at fair value on a recurring basis as of October 30, 2010 were as follows (in thousands):

(2) During fiscal year 2009, the Company transferred $4.7 million of corporate bonds from assets utilizing Level 1 inputs to assets utilizing Level 2 inputs due to a decrease in quotable prices in an active market, as well as a less active market for the bonds.

The Company uses a midpoint of the highest bid and lowest offering obtained from market makers to value its corporate bonds. The Company uses observable market prices for comparable instruments to value its derivative instruments.

9. Borrowings

Senior Secured Notes

On January 20, 2010, the Company issued $300.0 million aggregate principal amount of its 6.625% Senior Secured Notes due 2018 at an issue price of 99.239% of the principal amount of the notes (the “2018 Notes”) and $300.0 million aggregate principal amount of its 6.875% Senior Secured Notes due 2020 at an issue price of 99.114% of the principal amount of the notes (the “2020 Notes” and, together with the 2018 Notes, the “Senior Secured Notes”), in a private placement to “qualified institutional buyers” in the United States defined in Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and outside the United States pursuant to Regulation S under the Securities Act (the “Notes Offering”). The 2018 Notes mature on January 15, 2018 and bear interest at a rate of 6.625% per annum, payable semi-annually on January 15 and July 15 of each year, commencing on July 15, 2010. The 2020 Notes mature on January 15, 2020 and bear interest at a rate of 6.875% per annum, payable semi-annually on January 15 and July 15 of each year, commencing on July 15, 2010. The Company’s obligations under the Senior Secured Notes are guaranteed by certain of the Company’s domestic subsidiaries (the “Subsidiary Guarantors”). The obligations of the Company and the Subsidiary Guarantors under the Senior Secured Notes and the related guarantees are secured by liens, subject to certain exceptions and permitted liens and subject to the terms of an intercreditor agreement, on all assets of the Company and the Subsidiary Guarantors that secure any obligations under the Senior Secured Credit Facility, as described below.

The Company used approximately $435.0 million of the net proceeds of the Notes Offering to prepay a portion of the outstanding term loan under the Senior Secured Credit Facility on January 20, 2010, and used the remaining net proceeds, together with cash on hand, to retire on February 16, 2010 the 2.25% subordinated convertible notes (“2.25% Notes”) originally issued by McDATA, a wholly owned subsidiary of Brocade.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

As of October 30, 2010, the liability associated with the 2018 Notes of $297.9 million, net of the debt discount of $2.1 million, and the liability associated with the 2020 Notes of $297.5 million, net of the debt discount of $2.5 million, are together reported as “Senior Secured Notes,” on the Consolidated Balance Sheets.

Debt issuance costs totaling $11.0 million associated with the Senior Secured Notes are classified entirely as long-term and have been capitalized as deferred financing costs, with $0.7 million amortized as of October 30, 2010. As of October 30, 2010, deferred financing costs were $10.3 million and are reported within “Other assets” on the Consolidated Balance Sheets. The deferred financing costs of the 2018 Notes and the 2020 Notes are being amortized using the effective interest method over the eight-year and ten-year term of the debt, respectively. No payments were made towards the principal of the Senior Secured Notes during the fiscal year ended October 30, 2010. As of October 30, 2010, the approximate fair value of the Company’s senior secured notes was $645.4 million, estimated based on broker trading prices.

The 2018 Notes were issued pursuant to an indenture, dated as of January 20, 2010 (the “2018 Indenture”), among the Company, the Subsidiary Guarantors and Wells Fargo Bank, National Association, as trustee. The 2020 Notes were issued pursuant to an indenture, dated as of January 20, 2010 (the “2020 Indenture” and, together with the 2018 Indenture, the “Indentures”), among the Company, the Subsidiary Guarantors and Wells Fargo Bank, National Association, as trustee.

On or after January 15, 2013, the Company may redeem all or a part of the 2018 Notes at the redemption prices set forth in the 2018 Indenture, plus accrued and unpaid interest and special interest, if any, to the applicable redemption date. In addition, at any time prior to January 15, 2013, the Company may, on one or more than one occasion, redeem some or all of the 2018 Notes at any time at a redemption price equal to 100% of the principal amount of the 2018 Notes redeemed, plus a “make-whole” premium as of, and accrued and unpaid interest and special interest, if any, to the applicable redemption date. On or after January 15, 2015, the Company may redeem all or a part of the 2020 Notes at the redemption prices set forth in the 2020 Indenture, plus accrued and unpaid interest and special interest, if any, to the applicable redemption date. In addition, at any time prior to January 15, 2015, the Company may, on one or more than one occasion, redeem some or all of the 2020 Notes at any time at a redemption price equal to 100% of the principal amount of the 2020 Notes redeemed, plus a “make-whole” premium as of, and accrued and unpaid interest and special interest, if any, to the applicable redemption date. At any time prior to January 15, 2013, the Company may also redeem up to 35% of the aggregate principal amount of the 2018 Notes and 2020 Notes, using the proceeds of certain qualified equity offerings, at the redemption prices set forth in the 2018 Indenture and the 2020 Indenture, respectively.

If the Company experiences specified change of control triggering events, it must offer to repurchase the Senior Secured Notes at a repurchase price equal to 101% of the principal amount of the Senior Secured Notes repurchased, plus accrued and unpaid interest and special interest, if any, to the applicable repurchase date. If the Company or its subsidiaries sell assets under certain specified circumstances, the Company must offer to repurchase the Senior Secured Notes at a repurchase price equal to 100% of the principal amount of the Senior Secured Notes repurchased, plus accrued and unpaid interest and special interest, if any, to the applicable repurchase date.

Each of the Indentures contains covenants that, among other things, restrict the ability of the Company and its restricted subsidiaries to:

• pay dividends, make investments or make other restricted payments;

• incur additional indebtedness;

• sell assets;

89

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

• enter into transactions with affiliates;

• incur liens;

• permit consensual encumbrances or restrictions on the Company’s restricted subsidiaries’ ability to pay dividends or make certain other payments to the Company;

• consolidate, merge, sell or otherwise dispose of all or substantially all of the Company’s or its restricted subsidiaries’ assets; and

• designate subsidiaries as unrestricted.

These covenants are subject to a number of other limitations and exceptions set forth in the Indentures. The Company was in compliance with all applicable covenants as of October 30, 2010.

Each of the Indentures provides for customary events of default, including, but not limited to, cross defaults to specified other debt of the Company and its subsidiaries. In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding Senior Secured Notes will become due and payable immediately without further action or notice. If any other event of default under either indenture occurs or is continuing, the applicable trustee or holders of at least 25% in aggregate principal amount of the then outstanding 2018 Notes or 2020 Notes, as applicable, may declare all of the 2018 Notes or 2020 Notes, respectively, to be due and payable immediately.

In connection with the issuance of the Senior Secured Notes, the Company and the Subsidiary Guarantors also entered into registration rights agreements with the initial purchasers relating to each series of the Senior Secured Notes. Under the terms of these registration rights agreements, with respect to each series of the Senior Secured Notes, the Company and the Subsidiary Guarantors are required to use commercially reasonable efforts to file with the SEC a registration statement relating to an offer to exchange the applicable series of notes for an issue of SEC-registered notes (the “Exchange Notes”) with terms identical to the applicable series of the Senior Secured Notes (except that the Exchange Notes will not be subject to restrictions on transfer or to any increase in annual interest rate) and maintain the effectiveness of such registration statement until 180 days after the closing of the applicable exchange offer. In addition, the Company and the Subsidiary Guarantors were required to consummate each exchange offers within 60 days after the effective date of the registration statement and in the event the Company and the Subsidiary Guarantors failed to consummate an exchange offer by January 20, 2011, additional interest up to 1.0% per annum would have been payable on the applicable series of Senior Secured Notes. The Company and the Subsidiary Guarantors filed a registration statement on Form S-4 relating to such an offer to exchange on June 18, 2010, the registration statement was declared effective by the SEC on August 24, 2010, and both exchange offers were consummated on October 1, 2010.

Senior Secured Credit Facility

On October 7, 2008, the Company entered into a credit agreement with the following lenders, Bank of America, N.A., Morgan Stanley Senior Funding, Inc., Banc of America Securities LLC, HSBC Bank USA National Association and Keybank National Association. The credit agreement provides for (i) a five-year $1,100.0 million term loan facility and (ii) a five-year $125.0 million revolving credit facility, which includes a $25.0 million swing line loan subfacility and a $25.0 million letter of credit subfacility. On January 8, 2010, the Company entered into an amendment and waiver to the credit agreement, among other things, (i) to increase flexibility under certain financial and other covenants, (ii) to permit the Company to issue additional senior indebtedness in aggregate principal amount outstanding at any time of up to $600.0 million, (iii) to permit the Company to issue additional subordinated indebtedness in aggregate principal amount outstanding at any time of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

up to $600.0 million, and (iv) to permit the Company to sell its accounts receivable and lease receivables for fair market value with the aggregate amount paid for such receivables, net of collections, not at any time exceeding $125.0 million. On January 20, 2010, the Company closed its offering of its 2018 Notes and its 2020 Notes as described above. The Company applied approximately $435.0 million of the proceeds of this offering to prepay the term loan, whereupon the amendment and waiver to credit agreement became effective.

The net proceeds of the term loan facility were used to finance a portion of the Company’s acquisition of Foundry. In addition to the term loan facility, during the year ended October 31, 2009, the Company drew $14.1 million from the $125.0 million revolving credit facility to finance a small portion of the merger. The Company may draw additional proceeds from the revolving credit facility in the future for ongoing working capital and other general corporate purposes. The term loan facility and revolving credit facility are referred to together as the “Senior Secured Credit Facility.” On April 30, 2010, the Company fully paid off the principal of the revolving credit facility for an approximate total amount of $14.1 million.

Loans under the Senior Secured Credit Facility bear interest, at the Company’s option, at a rate equal to either the London Interbank Offered Rate (“LIBOR rate”), plus an applicable margin equal to 4.0% per annum or the prime lending rate, plus an applicable margin equal to 3.0% per annum. The applicable margin with respect to revolving loans is subject to adjustment based on the Company’s consolidated senior secured leverage ratio, as defined in the credit agreement. The LIBOR rate floor is 3.0% per annum and the prime lending rate floor is 4.0% per annum, in each case, for the life of the Senior Secured Credit Facility. For the fiscal year ended October 30, 2010, the weighted-average interest rate on the term loan was 7.0%.

The Company is permitted to make voluntary prepayments at any time (without payment of a premium, other than in the case of a repricing transaction in respect of the term loan facility), and is required to make mandatory prepayments on the term loan (without payment of a premium) with (i) net cash proceeds from non-ordinary course asset sales (subject to reinvestment rights and other exceptions), (ii) net cash proceeds from issuances of debt (other than certain permitted debt), and (iii) casualty proceeds and condemnation awards (subject to reinvestment rights and other exceptions). The Company is required to pay quarterly installments on the term loan equal to an aggregate annual amount of 5% of the original principal amount thereof in the first and second year, 10% in the third year, 20% in the fourth year and 60% in the fifth year, with any remaining balance payable on the final maturity date of the term loan. Upon a repricing of the term loan (including through a refinancing) that results in the weighted-average yield or applicable rate of such term loan immediately after such repricing to be lower than such yield or rate immediately prior to such repricing, a 2.0% premium is payable during the first year following the closing and a 1.0% premium is payable during the second year following the closing.

Debt issuance costs totaling $31.6 million associated with financing the acquisition have been capitalized as deferred financing costs, with $14.3 million amortized as of October 30, 2010. As of October 30, 2010 and October 31, 2009, deferred financing costs were $17.3 million and $21.4 million, respectively, and are reported within “Other assets” on the Consolidated Balance Sheets. The deferred financing costs are being amortized using the effective interest method over the five-year term of the debt. During the twelve months ended October 30, 2010, the Company paid $583.0 million towards the principal of the term loan, $560.0 million of which were voluntary prepayments. As of October 30, 2010, the approximate fair value of the Company’s senior secured credit facility was $354.5 million, estimated based on broker trading prices.

The obligations of the Company and its subsidiary guarantors under the Senior Secured Credit Facility and the related guarantees there under are secured, subject to customary permitted liens and other agreed upon exceptions, by (i) a first priority pledge of all of the equity interests of each of the Company’s direct and indirect

91

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

subsidiaries and (ii) a perfected first priority interest in and mortgages on all tangible and intangible assets of the Company and each subsidiary guarantor, except, in the case of a foreign subsidiary, to the extent such pledge would be prohibited by applicable law or would result in materially adverse tax consequences (limited, in the case of a first-tier foreign subsidiary, to 65% of the voting stock and 100% of the non-voting stock of such first-tier foreign subsidiary). In addition, the term loan has not been registered with the SEC as of October 30, 2010.

The credit agreement contains customary representations and warranties and customary affirmative and negative covenants applicable to the Company and its subsidiaries, including, among other things, restrictions on liens, indebtedness, investments, fundamental changes, dispositions, capital expenditures, prepayment of other indebtedness, redemption or repurchase of subordinated indebtedness, share repurchases, dividends and other distributions. The credit agreement contains financial covenants that require the Company to maintain a minimum consolidated fixed charge coverage ratio, a maximum consolidated leverage ratio and a maximum consolidated senior secured leverage ratio, each as defined in the credit agreement and described further below. The credit agreement also includes customary events of default, including cross-defaults on the Company’s material indebtedness and change of control. The Company was in compliance with all applicable covenants as of October 30, 2010 and October 31, 2009.

Covenant Compliance

Under the Senior Secured Credit Facility and the associated indentures, certain limitations, restrictions and defaults could occur if the Company is not able to satisfy and remain in compliance with specified financial ratios.

Consolidated Earnings Before Interest, Taxes, Depreciation and Amortization (“EBITDA”), as defined in the credit agreement, is used to determine the Company’s compliance with certain covenants in the Senior Secured Credit Facility. Consolidated EBITDA is defined as:

• Consolidated net income

Plus:

• Consolidated interest charges;

• Provision for federal, state, local and foreign income taxes;

• Depreciation and amortization expense;

• Fees, costs and expenses incurred on or prior to the closing date in connection with the acquisition and the financing thereof;

• Non-cash restructuring charges incurred in connection with the acquisition, all as approved by Banc of America Securities LLC and Morgan Stanley Senior Funding, Inc.;

• Other non-recurring expenses reducing consolidated net income which do not represent a cash item in such period or future periods;

• Any non-cash stock-based compensation expense; and

• Legal fees associated with the indemnification obligations for the benefit of former officers and directors in connection with Brocade’s historical stock option litigation;

Minus:

• Federal, state, local and foreign income tax credits; and

• All non-cash items increasing consolidated net income.

In addition, the Company must comply with the following financial covenants as noted below:

Consolidated Fixed Charge Coverage Ratio

Consolidated fixed charge coverage ratio means, at any date of determination, the ratio of (a) (i) consolidated EBITDA (excluding interest expense attributable to the campus sale-leaseback), plus (ii) rentals payable under leases of real property, less (iii) the aggregate amount of all capital expenditures to (b) consolidated fixed charges; provided that, for purposes of calculating the consolidated fixed charge coverage ratio for any period ending prior to the first anniversary of the closing date, consolidated interest charges shall be an amount equal to actual consolidated interest charges from the closing date through the date of determination multiplied by a fraction the numerator of which is 365 and the denominator of which is the number of days from the closing date through the date of determination.

In accordance with the amendment and waiver to the credit agreement, the Company has agreed that it will not permit the consolidated fixed charge coverage ratio as of the end of any fiscal quarter during any period set forth below to be less than the ratio set forth below opposite such period:

Four Fiscal Quarters Ending During Period:	Minimum Consolidated Fixed Charge Coverage Ratio

Convertible Subordinated Debt

On January 29, 2007, effective upon the consummation of the merger with McDATA, the Company fully and unconditionally guaranteed and became a co-obligor on the 2.25% Notes of McDATA. The 2.25% Notes were convertible into McDATA’s Class A common stock at a conversion rate of 93.3986 shares per $1,000 principal amount of notes (aggregate of approximately 16.1 million shares) at any time prior to February 15, 2010, subject to adjustments. Pursuant to Brocade’s merger agreement with McDATA, at the effective time of the merger, each outstanding share of McDATA’s Class A common stock, $0.01 par value per share, was converted into the right to receive 0.75 of a share of Brocade’s common stock, $0.001 par value per share, together with cash in lieu of fractional shares. Concurrent with the issuance of the 2.25% Notes, McDATA entered into share option transactions using approximately $20.5 million of net proceeds. As part of these share option transactions, McDATA purchased options that cover approximately 12.1 million shares of common stock, at a strike price of $14.28. McDATA also sold options that cover approximately 12.7 million shares of common stock, at a strike price of $20.11. The net cost of the share option transactions was recorded against additional paid-in capital. On February 16, 2010, the Company fully paid off the principal of the 2.25% Notes for a total amount of $172.5 million.

Company Campus Contractual Obligations. On May 23, 2008, Brocade purchased property located in San Jose, California, which consisted of three unimproved building parcels that were entitled for approximately 562,000 square feet of space in three buildings. The total purchase price for the property was $50.9 million. In connection with the purchase, Brocade also engaged a third party as development manager to manage the development and construction of improvements on the property. Brocade’s obligation for development and construction of three buildings and a parking garage on the purchased property was approximately $176.3 million (in addition to the purchase price for the property), payable in various installments through approximately January 2011. Brocade’s obligation for tenant improvements for the campus was approximately $80.2 million, in addition to the $8.0 million that the Company has agreed to pay the developer on May 22, 2011 or earlier. Brocade financed the purchase and the development through operating cash flows. In connection with the purchase, Brocade also obtained a four-year option, exercisable at its sole discretion through May 22, 2012, to purchase a fourth unimproved approximate four acre parcel for a fixed price of approximately $26.0 million. The costs incurred to date in connection with the Company campus are approximately $305.0 million and the remaining capital expenditures are approximately $10.4 million as of October 30, 2010.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

(1) Included in the $4.5 million in liabilities accrued for warranties issued during the year ended October 31, 2009 is $1.9 million in warranty liabilities assumed as part of the Foundry acquisition.

In addition, the Company has standard indemnification clauses contained within its various customer contracts. As such, the Company indemnifies the parties to whom it sells its products with respect to the Company’s product infringing upon any patents, trademarks, copyrights, or trade secrets, as well as against bodily injury or damage to real or tangible personal property caused by a defective Company product. As of October 30, 2010, there have been no known material events or circumstances that have resulted in a customer contract-related indemnification liability to the Company.

Manufacturing and Purchase Commitments

Brocade has manufacturing arrangements with CMs under which Brocade provides twelve-month product forecasts and places purchase orders in advance of the scheduled delivery of products to Brocade’s customers. The required lead time for placing orders with the CMs depends on the specific product. The CMs invoice Brocade based on prices and payment terms mutually agreed upon and set forth in purchase orders it issues to them. Although the purchase orders Brocade places with its CMs are cancelable, the terms of the agreements require Brocade to purchase all inventory components not returnable, usable by, or sold to other customers of the CMs.

As of October 30, 2010, the Company’s aggregate commitment to the CMs for inventory components used in the manufacture of Brocade products was $284.4 million, which the Company expects to utilize during future normal ongoing operations, net of a purchase commitments reserve of $4.9 million. The Company’s purchase commitments reserve reflects the Company’s estimate of purchase commitments it does not expect to consume in normal ongoing operations within the next twelve months.

Income Taxes

The Company is subject to several ongoing audits. For additional discussion, see Note 15, “Income Taxes,” of the Notes to Consolidated Financial Statements. The Company believes it has adequate reserves for all open tax years.

Legal Proceedings

Initial Public Offering Litigation

On July 20, 2001, the first of a number of putative class actions for violations of the federal securities laws was filed in the United States District Court for the Southern District of New York against Brocade, certain of its officers and directors, and certain of the underwriters for Brocade’s initial public offering (“IPO”) of securities. A consolidated amended class action captioned, In re Brocade Communications Systems, Inc. Initial Public Offering Securities Litigation, No. 01 Civ. 6613, was filed on April 19, 2002. The complaint generally alleges that various underwriters engaged in improper and undisclosed activities related to the allocation of shares in Brocade’s initial public offering and seeks unspecified damages for claims under the Exchange Act on behalf of a purported class of purchasers of common stock from May 24, 1999 to December 6, 2000. The lawsuit against Brocade was coordinated for pretrial proceedings with a number of other pending litigations challenging underwriter practices in over 300 cases as In re Initial Public Offering Securities Litigation, 21 MC 92 (SAS), including actions against McDATA Corporation, Inrange Technologies Corporation (“Inrange”) (which was first acquired by Computer Network Technology Corporation (“CNT”) and subsequently acquired by McDATA as part of the CNT acquisition), and Foundry (collectively, the “Brocade Entities”), and certain of each entity’s respective officers and directors, and initial public offering underwriters.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The parties have reached a global settlement of the coordinated litigation, under which the insurers will pay the full amount of settlement share allocated to the Brocade Entities, and the Brocade Entities will bear no financial liability. On October 5, 2009, the Court granted final approval of the settlement. Certain objectors have appealed the Court’s final order.

Intellectual Property Litigation

On June 21, 2005, Enterasys Networks, Inc. (“Enterasys”) filed a lawsuit against Foundry (and Extreme Networks, Inc.) in the United States District Court for the District of Massachusetts alleging that certain of Foundry’s products infringe six of Enterasys’ patents and seeking injunctive relief, as well as unspecified damages. On August 28, 2007, the Court granted Foundry’s motion to stay the case based on petitions that Foundry had filed with the United States Patent and Trademark Office (“USPTO”) in 2007 for reexamination of five of the six Enterasys patents. Two of the patents received final rejections during their respective reexaminations, in which the USPTO held that the claims were invalid. Enterasys filed appeals of those rejections with the USPTO’s Board of Patent Appeals and Interferences in 2009. The USPTO issued reexamination certificates for the remaining three patents undergoing reexamination indicating that the patents were valid over the references that Foundry had submitted. On August 7, 2009, Brocade filed a new petition with the USPTO for reexamination of one of the patents that had received a reexamination certificate, but the USPTO upheld the patent as valid over the references that Brocade had submitted, and issued a reexamination certificate on July 6, 2010. On March 31, 2010, Brocade filed a new petition for reexamination of another of the patents that had received a reexamination certificate, and on December 1, 2010, the USPTO issued an initial Office Action rejecting the patent’s claims. Meanwhile, on May 21, 2010, the Court lifted the stay of the litigation, and Enterasys subsequently dropped from the litigation the two patents that are on appeal at the USPTO. Accordingly, four patents remain at issue in the litigation, of which one of the patents is currently undergoing reexamination in the USPTO. No trial date has been set.

On September 6, 2006, Chrimar Systems, Inc. (“Chrimar”) filed a lawsuit against Foundry (and D-Link Corporation and PowerDsine, Ltd.) in the United States District Court for the Eastern District of Michigan alleging that certain of Foundry’s products infringe Chrimar’s U.S. Patent 5,406,260 and seeking injunctive relief, as well as unspecified damages. Discovery has been completed. No trial date has been set.

On August 4, 2010, Brocade and Foundry Networks LLC (“Plaintiffs”) filed a lawsuit against A10 Networks, Inc. (“A10”), A10’s founder and other individuals in the United States District Court for the Northern District of California. On October 29, 2010, Plaintiffs filed an amended complaint. In the amended complaint, Brocade alleged that A10 and the individual defendants have misappropriated Plaintiff’s trade secrets, infringed copyrighted works, interfered with existing contracts between the Plaintiffs and their employees, breached contracts, breached their fiduciary duties and duties of loyalty, and that certain of A10’s products infringe ten of Brocade’s patents. Brocade is seeking injunctive relief, as well as monetary damages. The above action replaces and supplements the previous action against A10 filed by Brocade on April 23, 2010 in the United States District Court for the District of Delaware, which was dismissed without prejudice. No trial date has been set.

On November 10, 2010, A10 filed a lawsuit against Brocade and a Brocade reseller in the Superior Court of the State of California, in the County of Santa Clara. A10 alleges that Brocade obtained unauthorized access to an A10 product. A10 seeks compensatory and punitive damages, and injunctive relief. At the outset of the case, A10 sought a temporary restraining order enjoining any further access to the A10 product by Brocade, and for return of the product to A10. On November 11, 2010, the Court denied A10’s motion for a temporary restraining order. On November 30, 2010, Brocade filed a motion to stay the case in view of Brocade’s Federal Court lawsuit against A10. No trial date has been set.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

General

From time to time, the Company is subject to other legal proceedings and claims in the ordinary course of business, including claims of alleged infringement of trademarks, copyrights, patents and/or other intellectual property rights, and commercial contract disputes. Third parties assert patent infringement claims against the Company from time to time in the form of letters, lawsuits and other forms of communication. In addition, from time to time, the Company receives notification from customers claiming that they are entitled to indemnification or other obligations from the Company related to infringement claims made against them by third parties. Litigation, even if the Company is ultimately successful, can be costly and divert management’s attention away from the day-to-day operations of the Company.

The Company records a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. The Company reviews the need for any such liability on a quarterly basis. Except as may be noted above, the Company has not recorded any such material liabilities as of October 30, 2010 other than with respect to one litigation matter relating to a commercial contract dispute.

11. Derivative Instruments and Hedging Activities

In the normal course of business, the Company is exposed to fluctuations in interest rates and the exchange rates associated with foreign currencies. The Company’s primary objective for holding derivative financial instruments is to manage foreign currency exchange rate risk. The Company currently does not enter into derivative instruments to manage credit risk. However, the Company manages its exposure to credit risk through its investment policies. The Company generally enters into derivative transactions with high-credit quality counterparties and, by policy, limits the amount of credit exposure to any one counterparty based on its analysis of that counterparty’s relative credit standing. The amounts subject to credit risk related to derivative instruments are generally limited to the amounts, if any, by which a counterparty’s obligations exceed the Company’s obligations with that counterparty.

Foreign Currency Exchange Rate Risk

A majority of the Company’s revenue, expense and capital purchasing activities is transacted in U.S. dollars. However, the Company is exposed to foreign currency exchange rate risk inherent in conducting business globally in numerous currencies, of which the most significant to its operations for the fiscal year ended October 30, 2010 were the Chinese yuan, the euro, the Japanese yen, the British pound, the Singapore dollar and the Swiss franc. The Company is primarily exposed to foreign currency fluctuations related to operating expenses denominated in currencies other than the U.S. dollar. The Company has established a foreign currency risk management program to protect against fluctuations in the volatility of future cash flows caused by changes in foreign currency exchange rates. This program reduces, but does not always entirely eliminate, the impact of foreign currency exchange rate movements. The Company’s foreign currency risk management program includes foreign currency derivatives with cash flow hedge accounting designation that utilizes foreign currency forward contracts to hedge exposures to the variability in the U.S. dollar equivalent of anticipated non-U.S. dollar-denominated cash flows. These instruments generally have a maturity of less than one year. For these derivatives, the Company reports the after-tax gain or loss from the effective portion of the hedge as a component of accumulated other comprehensive loss in stockholders’ equity and reclassifies it into earnings in the same period in which the hedged transaction affects earnings as part of “Other income (loss), net” on the consolidated statements of operations.

The Company also may enter into other non-designated derivatives that consist primarily of forward contracts to minimize the risk associated with the foreign exchange effects of revaluing monetary assets and liabilities. Monetary assets and liabilities denominated in foreign currencies and any associated outstanding

99

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

forward contracts are marked-to-market with realized and unrealized gains and losses included in “Other income (loss), net.” There were no forward contracts of this nature outstanding as of October 30, 2010.

For amounts not associated with foreign currency forward contracts, gains and losses from transactions denominated in foreign currencies are included in the Company’s net income (loss) as part of “Other income (loss), net,” in the accompanying Consolidated Statements of Operations. The Company recognized foreign currency transaction losses of $6.6 million for the fiscal year ended October 30, 2010 and foreign currency transaction gains of $4.5 million and $4.6 million for the fiscal years ended October 31, 2009 and October 25, 2008, respectively.

Volume of Derivative Activity

Total gross notional amounts, presented by currency, are as follows (in thousands):

In United States Dollars	October 30, 2010		October 31, 2009
Euro	$	53,700	$	61,790
Japanese yen		14,306		11,523
British pound		22,018		23,991
Singapore dollar		12,427		15,319
Swiss franc		9,554		7,385
Total	$	112,005	$	120,008

The Company utilizes a rolling hedge strategy for the majority of its foreign currency forward contracts with cash flow hedge accounting designation that hedges exposures to the variability in the U.S. dollar equivalent of anticipated non-U.S. dollar-denominated cash flows. All of the Company’s foreign currency forward contracts are single delivery, which are settled at maturity involving one cash payment exchange.

Net unrealized loss positions are recorded within “Other accrued liabilities”, and net unrealized gain positions are recorded within “Prepaid and other current assets.” As of October 30, 2010, the Company had a gross unrealized gain of $6.7 million included in “Prepaid and other current assets.” The amount of $6.7 million represents effective hedges and is reported as a component of accumulated other comprehensive loss. Hedge ineffectiveness, which is reported in the Consolidated Statements of Operations, was not significant.

12. Equity Compensation Plans

In April 2009, the stockholders of Brocade approved the Company’s 2009 Stock Plan, 2009 Director Plan and 2009 Employee Stock Purchase Plan (“2009 ESPP”), and such plans are now part of the Company’s equity compensation plans. The Company’s 1999 Stock Plan, 1999 Director Option Plan and 1999 Employee Stock Purchase Plan each expired in March 2009 by their terms.

2009 Stock Plan

The 2009 Stock Plan provides for the grant of stock options, restricted stock, restricted stock units, stock appreciation rights, performance units and performance shares, and other stock or cash awards to employees, directors and consultants. Per the terms of the 2009 Stock Plan, 48.0 million shares of the Company’s common stock are reserved for issuance under the plan, plus the following:

• Any shares subject to stock options or similar awards granted under the Company’s 1999 Stock Plan, 1999 Nonstatutory Stock Option Plan (“NSO Plan”) and 2001 McDATA Equity Incentive Plan that expire or otherwise terminate without having been exercised in full; and

100

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

• Shares issued pursuant to awards granted under the Company’s 1999 Stock Plan, 1999 NSO Plan and 2001 McDATA Equity Incentive Plan that are forfeited to or repurchased by the Company, with the maximum number of shares to be added to the 2009 Stock Plan pursuant to this clause equal to 40,335,624 shares.

2009 Director Plan

The 2009 Director Plan provides for the grant of stock options and restricted stock units to non-employee directors of the Company. The Board of Directors has reserved 2.0 million shares of the Company’s common stock for issuance under the 2009 Director Plan, plus any shares subject to stock options or similar awards granted under the Company’s 1999 Director Option Plan that expire or otherwise terminate without having been exercised in full, and shares issued pursuant to awards granted under the Company’s 1999 Director Option Plan that are forfeited to or repurchased by the Company, with the maximum number of shares to be added to the 2009 Director Plan pursuant to this clause equal to 870,000 shares.

2009 Employee Stock Purchase Plan

The 2009 ESPP permits eligible employees to purchase shares of the Company’s common stock through payroll deductions for up to 15% of qualified compensation during the offering period. The purchase price is 85% of the lesser of the fair market value of the Company’s common stock on (i) the first trading day of the offering period, or (ii) the last day of each six-month purchase period; provided, however, that the purchase price for subsequent offering periods may be determined by the administrator, subject to compliance with the terms of the 2009 ESPP. A total of 35.0 million shares of the Company’s common stock are reserved for issuance under the 2009 ESPP. The 2009 ESPP is implemented through consecutive, overlapping offering periods of up to approximately twenty-four months. The offering periods generally start with the first trading day on or after June 1 and December 1 each year and end on the last trading day in the periods ending twenty-four months later, unless the fair market value of the Company’s common stock on the last day of a purchase period is lower than the fair market value of the Company’s common stock on the first trading day of the offering period, in which case the offering period will end early, immediately after the purchase period, and a new offering period will commence on or about such date. Each offering period will be divided into four purchase periods of approximately six months in length. Eligible employees may purchase no more than 3,750 shares of the Company’s common stock during each six-month purchase period. As of October 30, 2010, 27.2 million shares were available for issuance under the 2009 ESPP.

Equity Compensation Plans

The Company grants stock options, restricted stock awards and restricted stock units for shares of the Company’s common stock and other types of equity compensation awards to its employees and directors under the various equity compensation plans described above. In accordance with the terms of the 2009 Stock Plan and the 2009 Director Plan, each award granted with an exercise price that is less than fair market value, which includes all grants of restricted stock awards, restricted stock units, performance shares and performance units, will count against the applicable plan’s share reserve as 1.56 shares for every one share subject to such award. In addition, the exercise price of stock options and stock appreciation rights granted under the 2009 Stock Plan must be at least equal to the fair market value of the Company’s common stock on the date of grant and the exercise price of incentive stock options granted to any participant who owns more than 10% of the total voting power of all classes of the Company’s outstanding stock must be at least 110% of the fair market value of the Company’s common stock on the date of grant.

The term of a stock option and a stock appreciation right may not exceed seven years, except that, with respect to any participant who owns 10% of the voting power of all classes of the Company’s outstanding capital

101

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

stock, the term of an incentive stock option may not exceed five years. The majority of the stock options, restricted stock awards and restricted stock units granted under the Company’s equity compensation plans vest over a period of four years. Certain options and awards granted under the 2009 Stock Plan vest over shorter or longer periods.

At October 30, 2010, approximately 149.0 million shares were authorized for future issuance under the Company’s equity compensation plans, which include stock options, shares to be issued pursuant to the 2009 ESPP, restricted stock units and other awards, and shares of Brocade common stock that became issuable in connection with the assumption or substitution of Foundry equity awards. A total of 48.4 million shares of common stock were available for grant under the Company’s equity compensation plans as of October 30, 2010. At October 31, 2009, approximately 190.8 million shares were authorized for future issuance under the Company’s equity compensation plans, which include stock options, shares issued pursuant to the 2009 Employee Stock Purchase Plan, and restricted stock units and other awards. A total of 67.1 million shares of common stock were available for grant under the Company’s equity compensation plans as of October 31, 2009. Awards that expire, or are canceled without delivery of shares, generally become available for issuance under the Company’s equity compensation plans.

1999 Nonstatutory Stock Option Plan

In September 1999, the Board of Directors approved the Company’s 1999 NSO Plan. The 1999 NSO Plan provides for the grant of nonstatutory stock options to employees and consultants. A total of 51.4 million shares of the Company’s common stock have been reserved for issuance under the 1999 NSO Plan. As of October 30, 2010, the Company has reserved 18.8 million shares of authorized but unissued shares of common stock for future issuance upon exercise of options under the 1999 NSO Plan.

McDATA Equity Plans

On January 29, 2007, effective upon the consummation of the merger, Brocade assumed the McDATA equity plans. As of October 30, 2010, options to purchase approximately 2.8 million shares of converted common stock, restricted stock and other equity awards remained outstanding under former McDATA equity plans.

Long-Term Incentive Plan

On July 30, 2007, the Board of Directors approved a long-term, performance-based equity incentive plan under the Company’s then applicable 1999 Stock Plan. On November 24, 2009, the Compensation Committee of the Board of Directors approved the issuance of approximately 2.0 million RSUs under the Company’s long-term, performance-based equity incentive plan. The fair value of the restricted stock units granted under the Long-Term Incentive Plan was estimated using a Monte Carlo simulation which required assumptions for expected volatilities, correlation coefficients and risk-free interest rates. Expected volatilities were derived using a method that calculates historical volatility over a period equal to the length of the measurement period for the Long-Term Incentive Plan and the companies included in the related index. Correlation coefficients were based on the same data used to calculate historical volatilities and were used to model how our stock price moves in relation to the companies included in the related index. The Company used a risk-free interest rates that is equal to the yield of a zero-coupon U.S. Treasury bill that is commensurate with each measurement period. As of October 31, 2009, $17.7 million in compensation expense related to these awards had been recognized. Liability-classified awards are required to be remeasured to current fair value at each reporting date until settlement. In accordance with the applicable accounting standard, for the twelve months ended October 30, 2010, the Company recorded a $3.5 million benefit related to these awards as a result of the decrease in Brocade’s closing

share price on November 24, 2009, the date of settlement, from when these awards were fair valued as of October 31, 2009. As of October 30, 2010, Brocade has no remaining unrecognized compensation expense related to these awards.

Employee 401(k) Plan

The Company sponsors the Brocade Communications Systems, Inc. 401(k) Plan (“401(k) Plan”), which qualifies under Section 401(k) of the Internal Revenue Code and is designed to provide retirement benefits for its eligible employees through tax-deferred salary deductions.

Employees may elect to contribute up to 60% of their eligible compensation to the 401(k) Plan. Employee contributions are limited to a maximum annual amount as set periodically by the Internal Revenue Service (“IRS”). The Company matches employee contributions dollar for dollar up to a maximum of $3,000 per calendar year per person. All matching contributions vest immediately. The Company’s matching contributions to the 401(k) Plan totaled $8.7 million, $7.8 million and $5.8 million for the years ended October 30, 2010, October 31, 2009 and October 25, 2008, respectively.

13. Sale-Leaseback Transaction

During fiscal year 2010, the Company sold an owned property to an unrelated third party. Net proceeds from this sale were $30.2 million. Concurrent with this sale, the Company entered into an agreement to lease the property back from the purchaser over a minimum lease term of two years. The Company considers this lease as a normal leaseback and classified the lease as an operating lease. Beginning in the fourth fiscal quarter of 2010, the Company actively uses only a certain portion of the property and has recognized a reserve related to facilities lease loss for the unused portion. An $8.7 million loss on the sale of the property was recognized immediately upon execution of the sale and is recorded within “Gain (loss) on sale of investments and property, net” on the Consolidated Statements of Operations.

The following table presents unrecognized compensation expense, net of estimated forfeitures, of the Company’s equity compensation plans as of October 30, 2010, which is expected to be recognized over the following weighted-average periods, (in thousands, except for weighted-average period):

	Unrecognized Compensation Expense		Weighted- Average Period (in years)

Stock Options

When the measurement date is certain, the fair value of each option granted during the respective period is estimated on the date of grant using the Black-Scholes valuation model and the assumptions noted in the following table. The dividend yield reflects that Brocade has not paid any cash dividends since inception and does not anticipate paying cash dividends in the foreseeable future. The risk-free interest rate is based on the implied yield on a U.S. Treasury zero-coupon issue with a remaining term equal to the expected term of the option. The expected volatility is based on an equal weighted-average of implied volatilities from traded options of the Company’s common stock and historical volatility of the Company’s common stock. The expected term is based on historical exercise behavior.

The weighted-average grant date fair value of stock options granted during the years ended October 30, 2010, October 31, 2009 and October 25, 2008 was $2.89, $2.10 and $2.69, respectively. The total intrinsic value of stock options exercised for the years ended October 30, 2010, October 31, 2009 and October 25, 2008 was $51.7 million, $128.9 million and $12.4 million, respectively.

From May 1999 through July 2003, the Company granted 98.8 million options subject to variable accounting as the measurement date of the options granted was not certain. As of October 30, 2010, 0.5 million options with a weighted-average exercise price of $18.47 and a weighted-average contractual life of 1.16 years remain outstanding and continue to be accounted for under variable accounting.

Employee Stock Purchase Plan

Under Brocade’s employee stock purchase plans, including the 2009 ESPP and the 1999 Employee Stock Purchase Plan (together, the “Brocade ESPP”), eligible employees can participate and purchase shares semi-annually at the lower of 85% of the fair market value of the Company’s common stock on (i) the first trading day of the offering period, or (ii) the last day of each six-month purchase period. The Brocade ESPP permits eligible employees to purchase common stock through payroll deductions for up to 15% of qualified compensation. The

106

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

Company accounts for the Brocade ESPP as a compensatory plan and recorded compensation expense of $33.7 million, $22.7 million and $6.6 million for the years ended October, 30, 2010, October 31, 2009 and October 25, 2008, respectively. Compensation expense computed under the fair value method for ESPP shares issued is being amortized under a graded vesting method over the twenty-four month offering period. In addition, the Company accounts for changes in percentage contribution elected by employees, as well as decreases in the Company’s common stock price on the last day of each six-month purchase period as compared to the common stock price on the first trading day of the offering period, by applying modification accounting which results in an increase in compensation expense during the period of modification.

The fair value of the option component of Brocade ESPP shares was estimated using the Black-Scholes option pricing model using the following weighted-average assumptions:

	Fiscal Year Ended
Employee Stock Purchase Plan	October 30, 2010			October 31, 2009			October 25, 2008
Expected dividend yield		0.0	%		0.0	%		0.0	%
Risk-free interest rate		0.6	%		0.8	%		2.6	%
Expected volatility		67.8	%		76.4	%		43.0	%
Expected term (in years) (1)		1.5			1.2			0.5

(1) The ESPP shares valued for the years ended October 25, 2008 fall under the 1999 Employee Stock Purchase Plan, which is based on a six-month offering period.

In addition, as part of its acquisition of Foundry, the Company became the administrator of Foundry’s 1999 Employee Stock Purchase Plan (“Foundry ESPP”), which expired on May 31, 2009. As a result of Brocade’s assumption of rights under the Foundry ESPP, Foundry employees who became Brocade employees were granted the right to purchase shares of the Company’s common stock at the lower of 85% of the fair market value of the Company’s common stock, as adjusted in accordance with the Foundry Merger Agreement at (i) the beginning of a rolling two-year offering period or (ii) the end of each semi-annual offering period, subject to a plan limit on the number of shares that may be purchased in an offering period. During the year ended October 31, 2009, the Company issued 4.9 million shares under the Foundry ESPP. The Company accounts for the Foundry ESPP as a compensatory plan and recorded compensation expense of $2.5 million for the year ended October 31, 2009.

Restricted Stock Awards

No restricted stock awards were issued for the years ended October 30, 2010, October 31, 2009 and October 25, 2008. When and if granted, restricted stock awards are not transferable until fully vested, and all unvested shares upon termination are subject to repurchase. The fair value of each award is based on the Company’s closing stock price on the date of grant.

U.S. federal income taxes and foreign withholding taxes associated with the repatriation of earnings of the Company’s foreign subsidiaries were not provided for a cumulative total of $337.7 million of undistributed earnings of the Company’s foreign subsidiaries. The Company intends to reinvest current and accumulated earnings of its foreign subsidiaries for expansion of its business operations outside the United States for an indefinite period of time. If these earnings were distributed to the United States in the form of dividends or otherwise, or if the shares of the relevant foreign subsidiaries were sold or otherwise transferred, the Company could be subject to additional U.S. income taxes, net of foreign tax credits, and foreign withholding taxes. Determination of the amount of unrecognized deferred income tax liability related to these earnings is not practicable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

The Company believes that sufficient positive evidence exists from historical operations and projections of taxable income in future years to conclude that it was more likely than not that the Company would realize its deferred tax assets. Historical operations were impacted by discrete events that if excluded would show that the Company has cumulative profits for the prior 12 quarters ending October 30, 2010. Accordingly, the Company only applies a valuation allowance on the deferred tax assets relating to capital loss carryforwards and investments loss carryforward due to limited carryforward periods and the character of such tax attributes. In the event future income by jurisdiction is less than what is currently projected, the Company may be required to apply a valuation allowance to these deferred tax assets in jurisdictions for which realization is no longer determined to be more likely than not.

As of October 30, 2010, the Company had federal net operating loss carryforwards of $851.5 million, California state net operating loss carryforwards of $66.8 million and other significant states net operating loss carryforwards of approximately $152.2 million. Additionally, the Company had $97.3 million of federal tax credits and $131.9 million of state tax credits. The federal net operating loss and other tax credit carryforwards expire on various dates between 2018 through 2030. The state net operating loss and credit carryforwards expire on various dates between 2010 through 2030. Under the current tax law, net operating loss and credit carryforwards available to offset future income in any given year may be limited by statute or upon the occurrence of certain events, including significant changes in ownership interests.

As a result of the McDATA and Foundry acquisitions, all the tax attributes from both companies are subject to an annual limitation, but the Company expects to use all the tax attributes before expiration.

The Company applies a recognition threshold and measurement attribute for the financial statement recognition and measurement of an income tax position taken or expected to be taken on a tax return. Recognition of a tax position is determined when it is more likely than not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement with a taxing authority.

A reconciliation of the beginning and ending amount of total gross unrecognized tax benefits, excluding accrued net interest and penalties of $3.0 million, for the year ended October 30, 2010, is as follows (in thousands):

	October 30, 2010			October 31, 2009
Unrecognized tax benefits, beginning balance	$	170,947		$	118,259
Gross increases for tax positions taken in prior periods		2,666			43,106
Gross decreases for tax positions taken in prior periods		(4,618	)		(1,229	)
Gross increases for tax positions taken in current period		7,805			18,416
Changes due to settlements with taxing authorities		(37,366	)		(919	)
Reductions resulting from lapses of statutes of limitations		(2,622	)		(6,686	)
Unrecognized tax benefits, ending balance	$	136,812		$	170,947

As of October 30, 2010, the Company had unrecognized tax benefits of $128.9 million, all of which, if recognized, would result in a reduction of the Company’s effective tax rate.

For the year ended October 30, 2010, the Company recorded income tax benefit of $8.7 million, primarily as a result of foreign taxes, offset by discrete benefits from the release of certain reserves mainly relating to the

111

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

settlement of the Company’s fiscal year 2003 Internal Revenue Service (“IRS”) audit and related remeasurements of various uncertain tax positions, concession from the IRS on treatment of intercompany gross receipts for the research and development credits, Franchise Tax Board (“FTB”) research and development credits carried forward to fiscal year 2005, and statute expirations of tax years of foreign subsidiaries.

The timing of the resolution of income tax examinations, as well as the amounts and timing of related settlements, is highly uncertain. The Company believes that before the end of fiscal year 2011, it is reasonably possible that either certain audits will conclude or the statute of limitations relating to certain income tax examination periods will expire, or both. Given the uncertainty as to settlement terms, the timing of payments and the impact of such settlements on other uncertain tax positions, the range of estimated potential decreases in underlying uncertain tax positions is between $0 and $15 million.

The Company classifies interest and penalties related to unrecognized tax benefits as a component of income tax expense. During the year ended October 30, 2010, the Company expensed $0.9 million for net interest and penalties related to income tax liabilities through income tax expense. The total net interest and penalties accrued as of October 30, 2010 was $3.0 million. During the year ended October 31, 2009, the Company expensed $0.7 million for net interest and penalties related to income tax liabilities through income tax expense.

In June 2010, the Company executed a closing agreement for fiscal year 2003 with the IRS, resolving the issues related to Brocade’s transfer pricing arrangement. The Company’s fiscal years 2004 through 2008 are still under IRS examination. The IRS is contesting the Company’s transfer pricing for the cost sharing and buy-in arrangements with its foreign subsidiaries, and may make similar claims against the Company’s transfer pricing arrangements in future examinations. The calendar years 2006 and 2007 FTB audit of Foundry’s California income tax returns are ongoing. All of these audits are still ongoing and the Company believes its reserves are adequate to cover any potential assessments that may result from these examinations. Due to the availability of net operating losses and credits, the Company does not expect a significant tax liability from the settlement of the audits.

Of the total tax benefits (detriments) resulting from the exercise of employee stock options and employee participation in the Company’s equity compensation plans, the amounts recorded to stockholders’ equity were approximately $(2.2) million in fiscal year 2010, $(0.8) million in fiscal year 2009, and $18.6 million in fiscal year 2008.

16. Segment Information

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 (“CODM”), or decision-making group, in deciding how to allocate resources and in assessing performance. Currently, the CODM is the Chief Executive Officer.

As a result of the Foundry acquisition during the first quarter of fiscal year 2009, Brocade reorganized into four operating segments, of which two are individually reportable segments: Data Storage and Global Services; and two, Internet Protocol (“IP”) Layer 2-3 and IP Layer 4-7/ Application Delivery Products (“IP Layer 4-7/ADP”), are combined into one reportable segment: Ethernet Products. The objective of this new organization is to enable the Company to more effectively focus on growth opportunities, while being well-positioned to more rapidly scale and accommodate new business opportunities, including potential future acquisitions. These

112

BROCADE COMMUNICATIONS SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—(Continued)

segments are organized principally by product category. The types of products and services from which each reportable segment derives its revenues are as follows:

• Data Storage includes infrastructure products and solutions including directors, switches, routers, fabric-based software applications, distance/extension products, as well as management applications and utilities to centralize data management. Data Storage also includes the server portfolio, which is comprised of host bus adapters (“HBAs”), converged network adapters, mezzanine cards, as well as switch modules for bladed servers;

• Ethernet Products includes Open Systems Interconnection Reference Model (“OSI”) Layer 2-3 switches and routers which enable efficient use of bandwidth-intensive network business applications and digital entertainment on both local area networks and wide area networks, OSI Layer 4–7 switches which allow enterprises and service providers to build highly available network infrastructures that efficiently direct the flow of traffic, and file area network products and associated management solutions; and

• Global Services include break/fix maintenance, extended warranty, installation, consulting, network management, and related software maintenance and support revenue.

Financial decisions and the allocation of resources are based on the information from the Company’s internal management reporting system. At this point in time, the Company does not track all of its assets by operating segments. The majority of the Company’s assets as of October 30, 2010, October 31, 2009 and October 25, 2008 were attributable to its United States operations.

Summarized financial information by reportable segment for the years ended October 30, 2010, October 31, 2009 and October 25, 2008, based on the internal management reporting system, is as follows (in thousands):

17. Gain (Loss) on Sale of Investments and Property, net, and Loss on Impairment of Portfolio Investments

The Company had an immaterial gain on sale of investments for the year ended October 30, 2010 and immaterial loss on sale of investment for the year ended October 31, 2009. For the year ended October 25, 2008, the Company had $6.9 million in net loss on sale of investments primarily due to the sale of the Company’s equity investment in a publicly traded company. The Company also determined that the declines in the fair value for certain of its portfolio investments primarily associated with non-marketable investments were other-than-temporary due to the significant deterioration of the financial condition of the investees. As a result, for the year ended October 25, 2008, the Company recorded impairment charges of $8.8 million. The carrying value of the Company’s equity investments in non-publicly traded companies at October 30, 2010, October 31, 2009 and October 25, 2008 was $7.0 million, $6.8 million and $6.8 million, respectively.

During the year ended October 30, 2010, the Company recognized an $8.7 million loss on the sale of property. See Note 13, “Sale-Leaseback Transaction,” of the Notes to Consolidated Financial Statements.

19. Related Party and Other Transactions

During the normal course of business, the Company purchases certain equipment from vendors who are also its customers and with whom the Company has contractual arrangements. The equipment purchased by the Company is primarily used for testing purposes in its development labs or otherwise consumed internally. The Company believes that all such transactions are on an arms-length basis and are subject to terms no more favorable than those with unrelated parties.

20. Guarantor and Non-Guarantor Subsidiaries

On January 20, 2010, the Company issued in total $600.0 million aggregate principal amount of its Senior Secured Notes. As discussed in Note 9, “Borrowings,” of the Notes to Consolidated Financial Statements, the Company’s obligations under the Senior Secured Notes are guaranteed by certain of the Company’s domestic subsidiaries. The Senior Secured Notes are not guaranteed by the Company’s Canadian or other foreign subsidiaries. The following tables present consolidated financial statements for the parent company, the Subsidiary Guarantors and the foreign non-guarantor subsidiaries, respectively. The consolidated financial statements for prior periods have been adjusted due to changes to the accounting for convertible debt instruments. For additional discussion, see Note 2, “Summary of Significant Accounting Policies,” of the Notes to Consolidated Financial Statements.

Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, as of the end of the period covered by this Annual Report on Form 10-K (the “Evaluation Date”).

The purpose of this evaluation is to determine if, as of the Evaluation Date, our disclosure controls and procedures are effective such that the information required to be disclosed in our Securities and Exchange Commission (“SEC”) reports (i) is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms, and (ii) is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.

Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the Evaluation Date, our disclosure controls and procedures were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended October 30, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Management’s Report on Internal Control over Financial Reporting

The management of Brocade Communications Systems, Inc. is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rule 13a-15(f) or 15d-15(f) of the Securities Exchange Act of 1934. The Company’s internal control over financial reporting is a process designed by, or under the supervision of, the Company’s principal executive and principal financial officers, and effected by the Company’s Board of Directors, management and other personnel, 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 and includes those policies and procedures that:

• pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets of the Company;

• 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

• 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.

Our management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and procedures or internal control over financial reporting will prevent all errors and all fraud. A control system, no matter how well designed and implemented, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must

125

reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues within a company are detected. The inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and may not be detected.

Our management assessed the effectiveness of the Company’s internal control over financial reporting as of October 30, 2010, utilizing the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework. Based on our management’s assessment, we believe that, as of October 30, 2010, our internal control over financial reporting was effective based on those criteria. The effectiveness of our internal control over financial reporting as of October 30, 2010 has been audited by KPMG LLP, Brocade’s independent registered public accounting firm, as stated in their report which is included on page 127 of this Annual Report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Stockholders

Brocade Communications Systems, Inc.:

We have audited Brocade Communications Systems, Inc. and subsidiaries’ (the Company) internal control over financial reporting as of October 30, 2010, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting appearing in Item 9A. 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, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included 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 U.S. 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 U.S. 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, the Company maintained, in all material respects, effective internal control over financial reporting as of October 30, 2010, based on criteria established in Internal Control—Integrated Framework issued by the COSO.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Brocade Communications Systems, Inc. and subsidiaries as of October 30, 2010 and October 31, 2009, and the related consolidated statements of operations, stockholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended October 30, 2010. In connection with our audits of the consolidated financial statements, we have also audited the accompanying financial statement schedule. Our report dated December 17, 2010 expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.

Amendment # 6 to Goods Agreement

10/22/2010

This Amendment No. 6, (“Amendment”) amends the terms and conditions of Goods Agreement # (Buyer #4999RO0015 and Supplier # ROC-P-68) (“GA”) between International Business Machines Corporation (“Buyer”) and Brocade Communications Systems, Incorporated (“Supplier”). Unless otherwise noted, this Amendment is effective upon signature of both parties. Transactions performed under this Amendment will be conducted in accordance with and be subject to the terms and conditions of this Amendment and the GA, and any applicable Work Authorizations “(WA’s”). Any capitalized terms not defined in this Amendment will have the meaning set forth in the GA. In the event of a conflict in the terms of this Amendment and that of the BA or SOW, the order of precedence will be: (i) this Amendment, (ii) the GA.

The parties agree to amend the GA as follows:

1. Delete Section 8.1, Paragraph 1, “Microcode License” in its entirety and replace with the following Section 8.1, Paragraph 1:

• Microcode License – Supplier hereby grants Buyer a non-exclusive, worldwide, right and license under all applicable intellectual property rights of Supplier to (i) use, execute and display all device drivers, firmware and software of Supplier used in the support and operation of the Products, including upgrades, updates, bug fixes or back-up versions of the same (“the Microcode”), in object code format only, in conjunction with, or for use with the Products, (ii) reproduce, distribute and license the Microcode, in object code format only, as part of, in conjunction with or for use with the Products sold or leased by Buyer to end users and as part of a standalone diagnostic, update, utility or CIM/CDM Provider distributed by Buyer, (iii) reproduce and distribute the Microcode, in object code format only, without any requirement that the Microcode be distributed with or used with the Products, but when the Microcode is included in Buyer’s software for use on a system that does not contain a Product, Buyer shall ensure that the Microcode is not evoked and remains latent at all times; and (iv) to authorize, license and sublicense third parties to do any, some or all of the foregoing. Buyer shall distribute the Microcode (as incorporated into the Products) with an end user agreement which is legally enforceable in the jurisdiction within which the Products are distributed, and which is no less protective of Supplier’s rights than this Agreement. All rights in and to the Microcode which are not granted to Buyer herein are expressly reserved to Supplier.

This Amendment and the GA as amended, are the sole and exclusive statement of the of the agreement between the parties with regard to the subject matter of this Amendment, and they supersede and replace any other agreement or understanding, whether written or oral, with regard to the subject matter. Any signed copy of this Amendment made by reliable means (e.g. photocopy or facsimile) shall be considered an original.

The Parties hereto have caused this Amendment to be signed by their respective duly authorized representatives.
