 SUMMARY
 
The Company
 
We design, manufacture, and sell Internet Protocol (IP)-based networking and other products related to the communications and information technology (IT) industry and provide services associated with these products and their use. We provide a broad line of products for transporting data, voice, and video within buildings, across campuses, and around the world. Our products are designed to transform how people connect, communicate, and collaborate. Our products are installed at enterprise businesses, public institutions, telecommunications companies, commercial businesses and personal residences.
 
We conduct our business globally and are managed geographically in five segments: the United States and Canada, European Markets, Emerging Markets, Asia Pacific, and Japan. The Emerging Markets theater consists of Eastern Europe, Latin America, the Middle East and Africa, and Russia and the Commonwealth of Independent States.
 
We sell IP-based networking and other products and services related to the communications and IT industry. Our products and services are designed to address a wide range of customers’ needs, including improving productivity, reducing costs, and gaining a competitive advantage. In addition, our products and services are designed to help customers build their own network infrastructures that support tools and applications that allow them to communicate with key stakeholders, including customers, prospects, business partners, suppliers, and employees. We focus on delivering networking products and solutions that are designed to simplify and secure customers’ network infrastructures. We believe that integrating multiple network services into our products helps our customers reduce their total cost of network ownership. Our product offerings fall into the following categories: our core technologies, routing and switching; advanced technologies; and other products. In addition to our product offerings, we provide a broad range of service offerings, including technical support services and advanced services. Our customer base spans virtually all types of public and private agencies and businesses, comprising enterprise businesses, service providers, commercial customers, and consumers.
 
Our products are used individually or as integrated offerings to connect personal and business computing devices to networks or computer networks with each other—whether they are within a building, across a campus, or around the world. Our breadth of product and service offerings across multiple technology segments enables us to offer a wide range of products and services to meet customer-specific requirements. We also provide products and services that allow customers to transition their various networks to a single multiservice data, voice, and video network, enabling economies of scale.

compared to net income of $2.2 billion, or $0.37 per fully diluted share (based on 6.0 billion shares used in per-share calculation), for the three months ended October 25, 2008.
 
Cash flows from operations were $1.5 billion for the first three months of fiscal 2010, compared with $2.7 billion for the first three months of fiscal 2009, and compared with $2.0 billion for the fourth quarter of fiscal 2009. Cash and cash equivalents and investments were $35.4 billion at the end of the first quarter of fiscal 2010, compared with $35.0 billion at the end of the fourth quarter of fiscal 2009.
 
Proposed Acquisitions of Tandberg ASA and Starent Networks, Corp.
 
On October 1, 2009, we announced our entry into an agreement to acquire Tandberg ASA for a cash purchase price of approximately $3.0 billion, although the purchase consideration is denominated in a foreign currency and, as such, the U.S. dollar equivalent is dependent on exchange rates. On October 13, 2009, we announced our entry into an agreement to acquire Starent Networks, Corp., under the terms of which we agreed to pay $35 per share in cash in exchange for each share of Starent Networks, Corp. and assume outstanding equity awards for an aggregate purchase price of approximately $2.9 billion. Each acquisition is subject to customary closing conditions, including the respective seller’s stockholder acceptance or approval and regulatory approvals, and each acquisition is expected to close in the first half of calendar year 2010, although there can be no assurance that either transaction will be completed on the terms to which we have agreed, or at all. In addition, any expected benefits to Cisco from completing these acquisitions will be subject to risks, including those referred to in the section of this prospectus supplement entitled “Risk Factors,” including the risk factor entitled “We have made and expect to continue to make acquisitions that could disrupt our operations and harm our operating results.”

Ratio of Earnings to Fixed Charges

For purposes of determining the ratio of earnings to fixed charges, “earnings” represent earnings before income taxes, noncontrolling interest and cumulative effect of accounting changes. “Fixed charges” represent interest expense plus that portion of rent expense that, in our opinion, approximates the interest component of rental expense.

 RISK FACTORS
 
Set forth below are risks and uncertainties that could cause our actual results to differ materially from the results contemplated by the forward-looking statements contained in this prospectus supplement, the accompanying prospectus and the documents incorporated by reference herein and therein.
 
Risks Related to Our Business
 
Our operating results may fluctuate in future periods, which may adversely affect our stock price.
 
Our operating results have been in the past, and will continue to be, subject to quarterly and annual fluctuations as a result of numerous factors, some of which may contribute to more pronounced fluctuations in an uncertain global economic environment. These factors include:
 
 	Ÿ	 	Fluctuations in demand for our products and services, especially with respect to telecommunications service providers and Internet businesses, in part due to changes in the global economic environment	
 
 	Ÿ	 	Changes in sales and implementation cycles for our products and reduced visibility into our customers’ spending plans and associated revenue	
 
 	Ÿ	 	Our ability to maintain appropriate inventory levels and purchase commitments	
 
 	Ÿ	 	Price and product competition in the communications and networking industries, which can change rapidly due to technological innovation and different business models from various geographic regions	
 
 	Ÿ	 	The overall movement toward industry consolidation among both our competitors and our customers	
 
 	Ÿ	 	The introduction and market acceptance of new technologies and products and our success in new and evolving markets, including emerging and advanced technologies, as well as the adoption of new standards	
 
 	Ÿ	 	Variations in sales channels, product costs, or mix of products sold	
 
 	Ÿ	 	The timing, size, and mix of orders from customers	
 
 	Ÿ	 	Manufacturing and customer lead times	
 
 	Ÿ	 	Fluctuations in our gross margins, and the factors that contribute to such fluctuations, as described below	
 
 	Ÿ	 	Our ability to achieve targeted cost reductions, such as the resource realignment and expense reduction that is described in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section in our 2009 Annual Report to Shareholders	
 
 	Ÿ	 	The ability of our customers, channel partners, contract manufacturers and suppliers to obtain financing or to fund capital expenditures, especially during a period of global credit market disruption or in the event of customer, channel partner, contract manufacturer or supplier financial problems	
 
 	Ÿ	 	Share-based compensation expense	
 
 	Ÿ	 	Actual events, circumstances, outcomes, and amounts differing from judgments, assumptions, and estimates used in determining the values of certain assets (including the amounts of related valuation allowances), liabilities, and other items reflected in our Consolidated Financial Statements	
 
 	Ÿ	 	How well we execute on our strategy and operating plans	
 
 	Ÿ	 	Benefits anticipated from our investments in engineering, sales and manufacturing activities	
 
S-8

Table of Contents

 	Ÿ	 	Changes in tax laws or regulations or accounting rules, such as increased use of fair value measures and the potential requirement that U.S. registrants prepare financial statements in accordance with International Financial Reporting Standards (IFRS)	
 
As a consequence, operating results for a particular future period are difficult to predict, and, therefore, prior results are not necessarily indicative of results to be expected in future periods. Any of the foregoing factors, or any other factors discussed elsewhere herein, could have a material adverse effect on our business, results of operations, and financial condition that could adversely affect our stock price.
 
Our operating results may be adversely affected by unfavorable economic and market conditions and the uncertain geopolitical environment.
 
Challenging economic conditions worldwide have from time to time contributed, and may continue to contribute, to slowdowns in the communications and networking industries at large, as well as to specific segments and markets in which we operate, resulting in:
 
 	Ÿ	 	Reduced demand for our products as a result of continued constraints on IT-related capital spending by our customers, particularly service providers, and other customer markets as well	
 
 	Ÿ	 	Increased price competition for our products, not only from our competitors but also as a consequence of customers disposing of unutilized products	
 
 	Ÿ	 	Risk of excess and obsolete inventories	
 
 	Ÿ	 	Risk of supply constraints	
 
 	Ÿ	 	Risk of excess facilities and manufacturing capacity	
 
 	Ÿ	 	Higher overhead costs as a percentage of revenue and higher interest expense	
 
The turmoil in the global credit markets, the instability in the geopolitical environment in many parts of the world and other disruptions, such as changes in energy costs, may continue to put pressure on global economic conditions. Our operating results in one or more segments may also be affected by uncertain or changing economic conditions particularly germane to that segment or to particular customer markets within that segment. The world has been experiencing a global macroeconomic downturn, and if global economic and market conditions, or economic conditions in the United States or other key markets, remain uncertain, persist, or deteriorate further, we may experience material impacts on our business, operating results, and financial condition.
 
During the recent global economic downturn and while the related market uncertainty persists, we have been investing in market adjacencies and also in the United States and select emerging countries, and if the return on these investments is lower or develops more slowly than we expect, our operating results may be harmed.
 
We continue to realign resources to focus on certain market adjacencies, such as enterprise data center virtualization, video/visual networking, collaboration architectures, and globalization, primarily in targeted geographic locations and to focus efforts particularly where we believe the economic recovery will progress the fastest, such as the United States and selected emerging countries, creating opportunities for us even while other countries or markets may not be recovering. However, the return on our investments in such market adjacencies and in such geographic markets may be lower, or may develop more slowly, than we expect. If we do not achieve the benefits anticipated from these investments (including if our selection of areas for investment does not play out as we expect), or if the achievement of these benefits is delayed, our operating results may be adversely affected.

Our revenue for a particular period is difficult to predict, and a shortfall in revenue may harm our operating results.
 
As a result of a variety of factors discussed in our Annual Report on Form 10-K for the year ended July 25, 2009, our revenue for a particular quarter is difficult to predict, especially in light of the recent global economic downturn and related market uncertainty. Our net sales declined in fiscal 2009 and may decline further or may grow at a slower rate than in past periods. Our ability to meet financial expectations could also be adversely affected if the nonlinear sales pattern seen in some of our past quarters recurs in future periods. We have experienced periods of time during which shipments have exceeded net bookings or manufacturing issues have delayed shipments, leading to nonlinearity in shipping patterns. In addition to making it difficult to predict revenue for a particular period, nonlinearity in shipping can increase costs, because irregular shipment patterns result in periods of underutilized capacity and periods in which overtime expenses may be incurred, as well as in potential additional inventory management-related costs. In addition, to the extent that manufacturing issues and any related component shortages result in delayed shipments in the future, and particularly in periods in which we and our contract manufacturers are operating at higher levels of capacity, it is possible that revenue for a quarter could be adversely affected if such matters occur and are not remediated within the same quarter.
 
The timing of large orders can also have a significant effect on our business and operating results from quarter to quarter, primarily in the United States and in our Emerging Markets theater and other emerging countries. From time to time, we receive large orders that have a significant effect on our operating results in the period in which the order is recognized as revenue. The timing of such orders is difficult to predict, and the timing of revenue recognition from such orders may affect period to period changes in net sales. As a result, our operating results could vary materially from quarter to quarter based on the receipt of such orders and their ultimate recognition as revenue.
 
Inventory management remains an area of focus. Similar to what is happening in the industry, we are seeing some product lead time extensions stemming from supplier constraints based upon their labor and other actions taken during the global economic downturn. Longer manufacturing lead times in the past have caused some customers to place the same order multiple times within our various sales channels and to cancel the duplicative orders upon receipt of the product, or to place orders with other vendors with shorter manufacturing lead times. Such multiple ordering (along with other factors) or risk of order cancellation may cause difficulty in predicting our sales and, as a result, could impair our ability to manage parts inventory effectively. In addition, our efforts to improve manufacturing lead-time performance may result in corresponding reductions in order backlog. A decline in backlog levels could result in more variability and less predictability in our quarter-to-quarter net sales and operating results. Increases in our purchase commitments to shorten lead times could also lead to excess and obsolete inventory charges if the demand for our products is less than our expectations.
 
We plan our operating expense levels based primarily on forecasted revenue levels. These expenses and the impact of long-term commitments are relatively fixed in the short term. A shortfall in revenue could lead to operating results being below expectations because we may not be able to quickly reduce these fixed expenses in response to short-term business changes.
 
Any of the above factors could have a material adverse impact on our operations and financial results.
 
We expect gross margin to vary over time, and our level of product gross margin may not be sustainable.
 
Our level of product gross margins may not be sustainable and may continue to be adversely affected by numerous factors, including:
 
 	Ÿ	 	Changes in customer, geographic, or product mix, including mix of configurations within each product group	
 
 	Ÿ	 	Introduction of new products, including products with price-performance advantages	
 
 	Ÿ	 	Our ability to reduce production costs	
 
 	Ÿ	 	Entry into new markets, including markets with different pricing and cost structures, through acquisitions or internal development

 	Ÿ	 	How well we execute on our strategy and operating plans	
 
Changes in service gross margin may result from various factors such as changes in the mix between technical support services and advanced services, as well as the timing of technical support service contract initiations and renewals and the addition of personnel and other resources to support higher levels of service business in future periods.
 
Sales to the service provider market are especially volatile, and weakness in sales orders from this industry may harm our operating results and financial condition.
 
Sales to the service provider market have been characterized by large and sporadic purchases, especially relating to our router sales and sales of certain of our advanced technologies, in addition to longer sales cycles. In the past, we have experienced significant weakness in sales to service providers over certain extended periods of time as market conditions have fluctuated. Sales activity in this industry depends upon the stage of completion of expanding network infrastructures; the availability of funding; and the extent to which service providers are affected by regulatory, economic, and business conditions in the country of operations. Weakness in orders from this industry, including as a result of any slowdown in capital expenditures by service providers (which may be more prevalent during a global economic downturn), could have a material adverse effect on our business, operating results, and financial condition. For example, during fiscal 2009, we experienced a slowdown in service provider capital expenditures globally, which may continue in future quarters. Orders from this industry could decline for many reasons other than the competitiveness of our products and services within their respective markets. For example, in the past, many of our service provider customers have been materially and adversely affected by slowdowns in the general economy, by overcapacity, by changes in the service provider market, by regulatory developments, and by constraints on capital availability, resulting in business failures and substantial reductions in spending and expansion plans. These conditions have materially harmed our business and operating results in the past, and some of these or other conditions in the service provider market could affect our business and operating results in any future period. Finally, service provider customers typically have longer implementation cycles; require a broader range of services, including design services; demand that vendors take on a larger share of risks; often require acceptance provisions, which can lead to a delay in revenue recognition; and expect financing from vendors. All these factors can add further risk to business conducted with service providers.
 
Disruption of or changes in our distribution model could harm our sales and margins.
 
If we fail to manage distribution of our products and services properly, or if our distributors’ financial condition or operations weaken, our revenue and gross margins could be adversely affected.
 
S-11

Table of Contents
A substantial portion of our products and services is sold through our channel partners, and the remainder is sold through direct sales. Our channel partners include systems integrators, service providers, other resellers, distributors, and retail partners. Systems integrators and service providers typically sell directly to end users and often provide system installation, technical support, professional services, and other support services in addition to network equipment sales. Systems integrators also typically integrate our products into an overall solution, and a number of service providers are also systems integrators. Distributors stock inventory and typically sell to systems integrators, service providers, and other resellers. In addition, home networking products are generally sold through distributors and retail partners. We refer to sales through distributors and retail partners as our two-tier system of sales to the end customer. Revenue from distributors and retail partners is recognized based on a sell-through method using information provided by them. These distributors and retail partners are generally given business terms that allow them to return a portion of inventory, receive credits for changes in selling prices, and participate in various cooperative marketing programs. If sales through indirect channels increase, this may lead to greater difficulty in forecasting the mix of our products and, to a degree, the timing of orders from our customers.
 
Historically, we have seen fluctuations in our gross margins based on changes in the balance of our distribution channels. Although variability to date has not been significant, there can be no assurance that changes in the balance of our distribution model in future periods would not have an adverse effect on our gross margins and profitability.
 
Some factors could result in disruption of or changes in our distribution model, which could harm our sales and margins, including the following:
 
 	Ÿ	 	We compete with some of our channel partners, including through our direct sales, which may lead these channel partners to use other suppliers that do not directly sell their own products or otherwise compete with them	
 
 	Ÿ	 	Some of our channel partners may demand that we absorb a greater share of the risks that their customers may ask them to bear	
 
 	Ÿ	 	Some of our channel partners may have insufficient financial resources and may not be able to withstand changes and challenges in business conditions	
 
 	Ÿ	 	Revenue from indirect sales could suffer if our distributors’ financial condition or operations weaken	
 
In addition, we depend on our channel partners globally to comply with applicable regulatory requirements. To the extent that they fail to do so, that could have a material adverse effect on our business, operating results, and financial condition.
 
The markets in which we compete are intensely competitive, which could adversely affect our achievement of revenue growth.
 
The markets in which we compete are characterized by rapid change, converging technologies, and a migration to networking and communications solutions that offer relative advantages. These market factors represent a competitive threat to us. We compete with numerous vendors in each product category. The overall number of our competitors providing niche product solutions may increase. Also, the identity and composition of competitors may change as we increase our activity in our advanced technology markets and market adjacencies. As we continue to expand globally, we may see new competition in different geographic regions. In particular, we have experienced price-focused competition from competitors in Asia, especially from China, and we anticipate this will continue. Our competitors include: Alcatel-Lucent; ARRIS Group, Inc.; Aruba Networks, Inc.; Avaya Inc.; Belden Inc.; Brocade Communications Systems, Inc.; Check Point Software Technologies Ltd.; Citrix Systems, Inc.; D-Link Corporation; LM Ericsson Telephone Company; Extreme Networks, Inc.; F5 Networks, Inc.; Force10 Networks, Inc.; Fortinet, Inc.; Hewlett-Packard Company; Huawei Technologies Co., Ltd.; International Business Machines Corporation; Juniper Networks, Inc.; LogMeIn, Inc.; Meru Networks, Inc.; Microsoft Corporation; Motorola, Inc.; NETGEAR, Inc.; Nortel Networks Corporation; Riverbed Technology, Inc.; and Symantec Corporation; among others.

Some of these companies compete across many of our product lines, while others are primarily focused in a specific product area. Barriers to entry are relatively low, and new ventures to create products that do or could compete with our products are regularly formed. In addition, some of our competitors may have greater resources, including technical and engineering resources, than we do. As we expand into new markets, we will face competition not only from our existing competitors but also from other competitors, including existing companies with strong technological, marketing, and sales positions in those markets. We also sometimes face competition from resellers and distributors of our products. Companies with whom we have strategic alliances in some areas may be competitors in other areas.
 
For example, the enterprise data center is undergoing a fundamental transformation arising from the convergence of technologies, including computing, networking, storage, and software, that previously were siloed. Due to several factors, including the availability of highly scalable and general purpose microprocessors, application-specific integrated circuits offering advanced services, standards based protocols, cloud computing and virtualization, the application of these converging technologies is spanning multiple, previously independent, technology segments. Also, some of our current and potential competitors for enterprise data center business have made acquisitions, or announced new strategic alliances, designed to position them to provide end-to-end technology solutions for the enterprise data center. As a result of all of these developments, we face greater competition in the development and sale of enterprise data center technologies, including competition from entities that are among our long-term strategic alliance partners. Companies that are strategic alliance partners in some areas of our business may acquire or form alliances with our competitors, thereby reducing their business with us.
 
The principal competitive factors in the markets in which we presently compete and may compete in the future include:
 
 	Ÿ	 	The ability to provide a broad range of networking and communications products and services	
 
 	Ÿ	 	Product performance	
 
 	Ÿ	 	Price	
 
 	Ÿ	 	The ability to introduce new products, including products with price-performance advantages	
 
 	Ÿ	 	The ability to reduce production costs	
 
 	Ÿ	 	The ability to provide value-added features such as security, reliability, and investment protection	
 
 	Ÿ	 	Conformance to standards	
 
 	Ÿ	 	Market presence	
 
 	Ÿ	 	The ability to provide financing	
 
 	Ÿ	 	Disruptive technology shifts and new business models	
 
We also face competition from customers to which we license or supply technology and suppliers from which we transfer technology. The inherent nature of networking requires interoperability. As such, we must cooperate and at the same time compete with many companies. Any inability to effectively manage these complicated relationships with customers, suppliers, and strategic alliance partners could have a material adverse effect on our business, operating results, and financial condition and accordingly affect our chances of success.
 
Our inventory management relating to our sales to our two-tier distribution channel is complex, and excess inventory may harm our gross margins.
 
We must manage our inventory relating to sales to our distributors and retail partners effectively, because inventory held by them could affect our results of operations. Our distributors and retail partners may increase orders during periods of product shortages, cancel orders if their inventory is too high, or delay orders in

anticipation of new products. They also may adjust their orders in response to the supply of our products and the products of our competitors that are available to them and in response to seasonal fluctuations in end-user demand. Revenue to our distributors and retail partners is recognized based on a sell-through method using information provided by them, and they are generally given business terms that allow them to return a portion of inventory, receive credits for changes in selling price, and participate in various cooperative marketing programs. Inventory management remains an area of focus as we balance the need to maintain strategic inventory levels to ensure competitive lead times against the risk of inventory obsolescence because of rapidly changing technology and customer requirements. If we ultimately determine that we have excess inventory, we may have to reduce our prices and write down inventory, which in turn could result in lower gross margins.
 
Supply chain issues, including financial problems of contract manufacturers or component suppliers, or a shortage of adequate component supply or manufacturing capacity that increased our costs or caused a delay in our ability to fulfill orders, could have an adverse impact on our business and operating results, and our failure to estimate customer demand properly may result in excess or obsolete component supply, which could adversely affect our gross margins.
 
The fact that we do not own or operate the bulk of our manufacturing facilities and that we are reliant on our extended supply chain could have an adverse impact on the supply of our products and on our business and operating results:
 
 	Ÿ	 	Any financial problems of either contract manufacturers or component suppliers could either limit supply or increase costs	
 
 	Ÿ	 	Reservation of manufacturing capacity at our contract manufacturers by other companies, inside or outside of our industry, could either limit supply or increase costs	
 
A reduction or interruption in supply; a significant increase in the price of one or more components; a failure to adequately authorize procurement of inventory by our contract manufacturers; a failure to appropriately cancel, reschedule, or adjust our requirements based on our business needs; or a decrease in demand for our products could materially adversely affect our business, operating results, and financial condition and could materially damage customer relationships. Furthermore, as a result of binding price or purchase commitments with suppliers, we may be obligated to purchase components at prices that are higher than those available in the current market. In the event that we become committed to purchase components at prices in excess of the current market price when the components are actually used, our gross margins could decrease. As the economic recovery takes hold, some tightening of supply has been observed in some components. See the risk factor above entitled “Our revenue for a particular period is difficult to predict, and a shortfall in revenue may harm our operating results.”
 
Our growth and ability to meet customer demands depend in part on our ability to obtain timely deliveries of parts from our suppliers and contract manufacturers. We have experienced component shortages in the past, including shortages caused by manufacturing process issues, that have affected our operations. We may in the future experience a shortage of certain component parts as a result of our own manufacturing issues, manufacturing issues at our suppliers or contract manufacturers, capacity problems experienced by our suppliers or contract manufacturers, or strong demand in the industry for those parts. A return to growth in the economy is likely to create greater pressures on us and our suppliers to accurately project overall component demand and component demands within specific product categories and to establish optimal component levels. For example, similar to what is happening in the industry we are seeing some product lead time extensions stemming from supplier constraints based upon their labor and other actions taken during the global economic downturn. If shortages or delays persist, the price of these components may increase, or the components may not be available at all, and we may also encounter shortages if we do not accurately anticipate our needs. We may not be able to secure enough components at reasonable prices or of acceptable quality to build new products in a timely manner in the quantities or configurations needed. Accordingly, our revenue and gross margins could suffer until other sources can be developed. Our operating results would also be adversely affected if, anticipating greater demand than actually develops, we commit to the purchase of more components than we need, which is more likely to

occur in a period of demand uncertainties such as we are currently experiencing. There can be no assurance that we will not encounter these problems in the future. Although in many cases we use standard parts and components for our products, certain components are presently available only from a single source or limited sources, and a global economic downturn and related market uncertainty could negatively impact one or more of these sources. We may not be able to diversify sources in a timely manner, which could harm our ability to deliver products to customers and seriously impact present and future sales.
 
We believe that we may be faced with the following challenges in the future:
 
 	Ÿ	 	New markets in which we participate may grow quickly, which may make it difficult to quickly obtain significant component capacity	
 
 	Ÿ	 	As we acquire companies and new technologies, we may be dependent, at least initially, on unfamiliar supply chains or relatively small supply partners	
 
 	Ÿ	 	We face competition for certain components that are supply-constrained, from existing competitors, and companies in other markets	
 
Manufacturing capacity and component supply constraints could be significant issues for us. We purchase components from a variety of suppliers and use several contract manufacturers to provide manufacturing services for our products. During the normal course of business, in order to improve manufacturing lead-time performance and to help ensure adequate component supply, we enter into agreements with contract manufacturers and suppliers that either allow them to procure inventory based upon criteria as defined by us or that establish the parameters defining our requirements. In certain instances, these agreements allow us the option to cancel, reschedule, and adjust our requirements based on our business needs prior to firm orders being placed. If we fail to anticipate customer demand properly, an oversupply of parts could result in excess or obsolete components that could adversely affect our gross margins. For additional information regarding our purchase commitments with contract manufacturers and suppliers, see Note 11 to the Consolidated Financial Statements contained in our 2009 Annual Report to Shareholders.
 
Our key manufacturing facility for Scientific-Atlanta’s products is located in Juarez, Mexico, and we may be materially and adversely affected by any prolonged disruption in the operation of this facility.
 
We depend upon the development of new products and enhancements to existing products, and if we fail to predict and respond to emerging technological trends and customers’ changing needs, our operating results and market share may suffer.
 
The markets for our products are characterized by rapidly changing technology, evolving industry standards, new product introductions, and evolving methods of building and operating networks. Our operating results depend on our ability to develop and introduce new products into existing and emerging markets and to reduce the production costs of existing products. We believe the industry is evolving to enable personal and business process collaboration enabled by networked Web 2.0, the technologies that enable user collaboration, as part of the second major phase of the Internet. As such, many of our strategic initiatives and investments are aimed at meeting the requirements that a network capable of multiple party, collaborative interaction would demand, and the investments we have made and our architectural approach are designed to enable networked Web 2.0 and the increased use of the network as the platform for all forms of communications and IT. Also, in March 2009 we launched our Unified Computing System (UCS), our next-generation enterprise data center platform architected to unite computing, network, storage access, and virtualization resources in a single system, which is designed to address the fundamental transformation occurring in the enterprise data center. UCS is one of several market adjacencies on which we are focusing resources. The process of developing new technology is complex and uncertain, and if we fail to accurately predict customers’ changing needs and emerging technological trends our business could be harmed. We must commit significant resources, including the investments we have been making in market adjacencies and in the United States and select emerging countries mentioned above, to developing new products before knowing whether our investments will result in products the market will accept. In particular, if our model of the evolution of networking to collaborative systems does not emerge as we believe it will, or if the industry does not evolve as we believe it will, or if our strategy for
 
S-15

Table of Contents
addressing this evolution is not successful, many of our strategic initiatives and investments may be of no or limited value. Furthermore, we may not execute successfully on that vision because of errors in product planning or timing, technical hurdles that we fail to overcome in a timely fashion, or a lack of appropriate resources. This could result in competitors providing those solutions before we do and loss of market share, net sales, and earnings. The success of new products depends on several factors, including proper new product definition, component costs, timely completion and introduction of these products, differentiation of new products from those of our competitors, and market acceptance of these products. There can be no assurance that we will successfully identify new product opportunities, develop and bring new products to market in a timely manner, or achieve market acceptance of our products or that products and technologies developed by others will not render our products or technologies obsolete or noncompetitive. The products and technologies that we identify as “emerging technologies” or “advanced technologies” may not prove to have the market success we anticipate, and we may not successfully identify and invest in other emerging or advanced technologies.
 
Over the long term we intend to increase our investment in engineering, sales, service and manufacturing activities, and these investments may achieve delayed, or lower than expected benefits which could harm our operating results.
 
While recently we have focused on managing our costs and expenses, over the long term, we intend to continue to add personnel and other resources to our engineering, sales, service, and manufacturing functions as we focus on developing emerging technologies, the next wave of advanced technologies, growing the commercial market segment, capitalizing on our emerging market opportunities, enhancing our evolving support model and increasing our market share gains. We are likely to recognize the costs associated with these investments earlier than some of the anticipated benefits, and the return on these investments may be lower, or may develop more slowly, than we expect. If we do not achieve the benefits anticipated from these investments, or if the achievement of these benefits is delayed, our operating results may be adversely affected.
 
Our business substantially depends upon the continued growth of the Internet and Internet-based systems.
 
A substantial portion of our business and revenue depends on growth and evolution of the Internet, including the continued development of networked Web 2.0 as part of the second major phase of the Internet, and on the deployment of our products by customers who depend on such continued growth and evolution. To the extent that an economic slowdown and reduction in capital spending adversely affect spending on Internet infrastructure, as we are currently seeing, we could experience material harm to our business, operating results, and financial condition.
 
Because of the rapid introduction of new products and changing customer requirements related to matters such as cost-effectiveness and security, we believe that there could be performance problems with Internet communications in the future, which could receive a high degree of publicity and visibility. Because we are a large supplier of networking products, our business, operating results, and financial condition may be materially adversely affected, regardless of whether or not these problems are due to the performance of our own products. Such an event could also result in a material adverse effect on the market price of our common stock independent of direct effects on our business.
 
Changes in industry structure and market conditions could lead to charges related to discontinuances of certain of our products or businesses and asset impairments.
 
In response to changes in industry and market conditions, we may be required to strategically realign our resources 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. Our estimates
 
S-16

Table of Contents
with respect to the useful life or ultimate recoverability of our carrying basis of assets, including purchased intangible assets, could change as a result of such assessments and decisions. Further, our estimates relating to the liabilities for excess facilities are affected by changes in real estate market conditions. Additionally, we are 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.
 
We have made and expect to continue to make acquisitions that could disrupt our operations and harm our operating results.
 
Our growth depends upon market growth, our ability to enhance our existing products, and our ability to introduce new products on a timely basis. We intend to continue to address the need to develop new products and enhance existing products through acquisitions of other companies, product lines, technologies, and personnel. Acquisitions involve numerous risks, including the following:
 
 	Ÿ	 	Difficulties in integrating the operations, systems, technologies, products, and personnel of the acquired companies, particularly companies with large and widespread operations and/or complex products, such as Scientific-Atlanta and WebEx	
 
 	Ÿ	 	Diversion of management’s attention from normal daily operations of the business and the challenges of managing larger and more widespread operations resulting from acquisitions	
 
 	Ÿ	 	Potential difficulties in completing projects associated with in-process research and development intangibles	
 
 	Ÿ	 	Difficulties in entering markets in which we have no or limited direct prior experience and where competitors in such markets have stronger market positions	
 
 	Ÿ	 	Initial dependence on unfamiliar supply chains or relatively small supply partners	
 
 	Ÿ	 	Insufficient revenue to offset increased expenses associated with acquisitions	
 
 	Ÿ	 	The potential loss of key employees, customers, distributors, vendors and other business partners of the companies we acquire following and continuing after announcement of acquisition plans	
 
Acquisitions may also cause us to:
 
 	Ÿ	 	Issue common stock that would dilute our current shareholders’ percentage ownership	
 
 	Ÿ	 	Use a substantial portion of our cash resources, as we did in connection with our fiscal 2007 acquisition of WebEx, or incur debt, as we did in fiscal 2006 when we issued and sold $6.5 billion in senior unsecured notes to fund our acquisition of Scientific-Atlanta	
 
 	Ÿ	 	Significantly increase our interest expense, leverage and debt service requirements if we incur additional debt to pay for an acquisition	
 
 	Ÿ	 	Assume liabilities	
 
 	Ÿ	 	Record goodwill and nonamortizable intangible assets that are subject to impairment testing on a regular basis and potential periodic impairment charges	
 
 	Ÿ	 	Incur amortization expenses related to certain intangible assets	
 
 	Ÿ	 	Incur tax expenses related to the effect of acquisitions on our intercompany research and development (R&D) cost sharing arrangement and legal structure	
 
 	Ÿ	 	Incur large and immediate write-offs and restructuring and other related expenses	
 
 	Ÿ	 	Become subject to intellectual property or other litigation	
 
Mergers and acquisitions of high-technology companies are inherently risky and subject to many factors outside of our control, and no assurance can be given that our previous or future acquisitions will be successful

and will not materially adversely affect our business, operating results, or financial condition. Failure to manage and successfully integrate acquisitions could materially harm our business and operating results. Prior acquisitions have resulted in a wide range of outcomes, from successful introduction of new products and technologies to a failure to do so. Even when an acquired company has already developed and marketed products, there can be no assurance that product enhancements will be made in a timely fashion or that pre-acquisition due diligence will have identified all possible issues that might arise with respect to such products.
 
From time to time, we have made acquisitions that resulted in charges in an individual quarter. These charges may occur in any particular quarter, resulting in variability in our quarterly earnings. In addition, our effective tax rate for future periods is uncertain and could be impacted by mergers and acquisitions. Risks related to new product development also apply to acquisitions. Please see the risk factors above, including the risk factor entitled “We depend upon the development of new products and enhancements to existing products, and if we fail to predict and respond to emerging technological trends and customers’ changing needs, our operating results and market share may suffer” for additional information.
 
Entrance into new or developing markets exposes us to additional competition and will likely increase demands on our service and support operations.
 
As we focus on new market opportunities—for example, storage; wireless; security; transporting data, voice, and video traffic across the same network; and other advanced technologies, emerging technologies and market adjacencies—we will increasingly compete with large telecommunications equipment suppliers as well as startup companies. Several of our competitors may have greater resources, including technical and engineering resources, than we do. Additionally, as customers in these markets complete infrastructure deployments, they may require greater levels of service, support, and financing than we have provided in the past, especially in the Emerging Markets theater. Demand for these types of service, support, or financing contracts may increase in the future. There can be no assurance that we can provide products, service, support, and financing to effectively compete for these market opportunities.
 
Further, provision of greater levels of services, support and financing by us may result in a delay in the timing of revenue recognition. In addition, entry into other markets, including our entry into the consumer market, has subjected and will subject us to additional risks, particularly to those markets, including the effects of general market conditions and reduced consumer confidence.
 
Industry consolidation may lead to increased competition and may harm our operating results.
 
There has been a trend toward industry consolidation in our markets for several years. We expect this trend to continue as companies attempt to strengthen or hold their market positions in an evolving industry and as companies are acquired or are unable to continue operations. For example, some of our current and potential competitors for enterprise data center business have made acquisitions, or announced new strategic alliances, designed to position them with the ability to provide end-to-end technology solutions for the enterprise data center. Companies that are strategic alliance partners in some areas of our business may acquire or form alliances with our competitors, thereby reducing their business with us. We believe that industry consolidation may result in stronger competitors that are better able to compete as sole-source vendors for customers. This could lead to more variability in our operating results and could have a material adverse effect on our business, operating results, and financial condition. Furthermore, particularly in the service provider market, rapid consolidation will lead to fewer customers, with the effect that loss of a major customer could have a material impact on results not anticipated in a customer marketplace composed of more numerous participants.
 
Product quality problems could lead to reduced revenue, gross margins, and net income.
 
We produce highly complex products that incorporate leading-edge technology, including both hardware and software. Software typically contains bugs that can unexpectedly interfere with expected operations. There can

be no assurance that our preshipment testing programs will be adequate to detect all defects, either ones in individual products or ones that could affect numerous shipments, which might interfere with customer satisfaction, reduce sales opportunities, or affect gross margins. In the past, we have had to replace certain components and provide remediation in response to the discovery of defects or bugs in products that we had shipped. Although the cost of such remediation has not been material in the past, there can be no assurance that such a remediation, depending on the product involved, would not have a material impact. An inability to cure a product defect could result in the failure of a product line, temporary or permanent withdrawal from a product or market, damage to our reputation, inventory costs, or product reengineering expenses, any of which could have a material impact on our revenue, margins, and net income.
 
Due to the global nature of our operations, political or economic changes or other factors in a specific country or region could harm our operating results and financial condition.
 
We conduct significant sales and customer support operations in countries outside of the United States; maintain a manufacturing facility for a substantial portion of our video systems products in Juarez, Mexico; and also depend on non-U.S. operations of our contract manufacturers, component suppliers and distribution partners. Although sales in our Emerging Markets theater have decreased during the recent global economic downturn, prior to such time our Emerging Markets theater has been a relatively fast growing theater, and we have announced plans to expand our commitments and expectations in this theater. As such, our growth depends in part on our increasing sales into this theater. We also intend to expand our level of business activity in two large emerging countries, India and China, and our growth in the Asia Pacific theater will also depend in part upon our increasing sales in these countries. Our future results could be materially adversely affected by a variety of factors relating to our operations outside the United States, any or all of which could have a material adverse effect on our operating results and financial condition, including, among others, the following:
 
 	Ÿ	 	The worldwide impact of the recent global economic downturn and related market uncertainty	
 
 	Ÿ	 	Foreign currency exchange rates	
 
 	Ÿ	 	Political or social unrest	
 
 	Ÿ	 	Economic instability or weakness or natural disasters in a specific country or region; environmental and trade protection measures and other legal and regulatory requirements, some of which may affect our ability to import our products to export our products from, or sell our products in various countries	
 
 	Ÿ	 	Political considerations that affect service provider and government spending patterns	
 
 	Ÿ	 	Health or similar issues, such as a pandemic or epidemic (including the H1N1 virus outbreak)	
 
 	Ÿ	 	Difficulties in staffing and managing international operations	
 
 	Ÿ	 	Adverse tax consequences, including imposition of withholding or other taxes on payments by subsidiaries	
 
We are exposed to the credit risk of some of our customers and to credit exposures in weakened markets, which could result in material losses.
 
Most of our sales are on an open credit basis, with typical payment terms of 30 days in the United States and, because of local customs or conditions, longer in some markets outside the United States. We monitor individual customer payment capability in granting such open credit arrangements, seek to limit such open credit to amounts we believe the customers can pay, and maintain reserves we believe are adequate to cover exposure for doubtful accounts. Beyond our open credit arrangements, we have also experienced demands for customer financing and facilitation of leasing arrangements. We expect demand for customer financing to continue, and recently we have been experiencing an increase in this demand as the credit markets have been impacted by the recent global economic downturn and related market uncertainty, including increased demand from customers in

certain countries within our Emerging Markets theater. We believe customer financing is a competitive factor in obtaining business, particularly in serving customers involved in significant infrastructure projects. Our loan financing arrangements may include not only financing the acquisition of our products and services but also providing additional funds for other costs associated with network installation and integration of our products and services.
 
Our exposure to the credit risks relating to our financing activities described above may increase if our customers are adversely affected by a global economic downturn, or if there is a continuation or worsening of the downturn. Although we have programs in place that are designed to monitor and mitigate the associated risk, including monitoring of particular risks in certain geographic areas, there can be no assurance that such programs will be effective in reducing our credit risks.
 
In the past, there have been significant bankruptcies among customers both on open credit and with loan or lease financing arrangements, particularly among Internet businesses and service providers, causing us to incur economic or financial losses. There can be no assurance that additional losses will not be incurred. Although these losses have not been material to date, future losses, if incurred, could harm our business and have a material adverse effect on our operating results and financial condition. A portion of our sales is derived through our distributors and retail partners. These distributors and retail partners are generally given business terms that allow them to return a portion of inventory, receive credits for changes in selling prices, and participate in various cooperative marketing programs. We maintain estimated accruals and allowances for such business terms. However, distributors tend to have more limited financial resources than other resellers and end-user customers and therefore represent potential sources of increased credit risk, because they may be more likely to lack the reserve resources to meet payment obligations. Additionally, to the degree that turmoil in the credit markets makes it more difficult for some customers to obtain financing, those customers’ ability to pay could be adversely impacted, which in turn could have a material adverse impact on our business, operating results, and financial condition.
 
We are exposed to fluctuations in currency exchange rates that could negatively impact our financial results and cash flows.
 
Because a significant portion of our business is conducted outside the United States, we face exposure to adverse movements in foreign currency exchange rates. These exposures may change over time as business practices evolve, and they could have a material adverse impact on our financial results and cash flows. Historically, our primary exposures have related to nondollar-denominated sales in Japan, Canada, and Australia and certain nondollar-denominated operating expenses and service cost of sales in Europe, Latin America, and Asia, where we sell primarily in U.S. dollars. Additionally, we have exposures to emerging market currencies, which can have extreme currency volatility. An increase in the value of the dollar could increase the real cost to our customers of our products in those markets outside the United States where we sell in dollars, and a weakened dollar could increase the cost of local operating expenses and procurement of raw materials to the extent that we must purchase components in foreign currencies.
 
Currently, we enter into foreign exchange forward contracts and options to reduce the short-term impact of foreign currency fluctuations on certain foreign currency receivables, investments, and payables. In addition, we periodically hedge anticipated foreign currency cash flows. Our attempts to hedge against these risks may not be successful, resulting in an adverse impact on our net income.
 
During the first quarter of fiscal 2010, we entered into transactions to hedge a portion of the foreign currency consideration payable in connection with our announced, pending acquisition of Tandberg ASA. These transactions produced gains that were recognized in the first quarter of 2010, and we could recognize losses or gains of a similar or greater magnitude in connection with those transactions or in connection with any similar transactions entered into in connection with that acquisition or future acquisitions. In addition, as the purchase consideration for Tandberg ASA is denominated in a foreign currency, the amount of U.S. dollar equivalent for the Tandberg ASA acquisition is dependent on exchange rates.

Our proprietary rights may prove difficult to enforce.
 
We generally rely on patents, copyrights, trademarks, and trade secret laws to establish and maintain proprietary rights in our technology and products. Although we have been issued numerous patents and other patent applications are currently pending, there can be no assurance that any of these patents or other proprietary rights will not be challenged, invalidated, or circumvented or that our rights will, in fact, provide competitive advantages to us. Furthermore, many key aspects of networking technology are governed by industrywide standards, which are usable by all market entrants. In addition, there can be no assurance that patents will be issued from pending applications or that claims allowed on any patents will be sufficiently broad to protect our technology. In addition, the laws of some foreign countries may not protect our proprietary rights to the same extent as do the laws of the United States. The outcome of any actions taken in these foreign countries may be different than if such actions were determined under the laws of the United States. Although we are not dependent on any individual patents or group of patents for particular segments of the business for which we compete, if we are unable to protect our proprietary rights to the totality of the features (including aspects of products protected other than by patent rights) in a market, we may find ourselves at a competitive disadvantage to others who need not incur the substantial expense, time, and effort required to create innovative products that have enabled us to be successful.
 
We may be found to infringe on intellectual property rights of others.
 
Third parties, including customers, have in the past and may in the future assert claims or initiate litigation related to exclusive patent, copyright, trademark, and other intellectual property rights to technologies and related standards that are relevant to us. These assertions have increased over time as a result of our growth and the general increase in the pace of patent claims assertions, particularly in the United States. Because of the existence of a large number of patents in the networking field, the secrecy of some pending patents, and the rapid rate of issuance of new patents, it is not economically practical or even possible to determine in advance whether a product or any of its components infringes or will infringe on the patent rights of others. The asserted claims and/or initiated litigation can include claims against us or our manufacturers, suppliers, or customers, alleging infringement of their proprietary rights with respect to our existing or future products or components of those products. Regardless of the merit of these claims, they can be time-consuming, result in costly litigation and diversion of technical and management personnel, or require us to develop a non-infringing technology or enter into license agreements. Where claims are made by customers, resistance even to unmeritorious claims could damage customer relationships. There can be no assurance that licenses will be available on acceptable terms and conditions, if at all, or that our indemnification by our suppliers will be adequate to cover our costs if a claim were brought directly against us or our customers. Furthermore, because of the potential for high court awards that are not necessarily predictable, it is not unusual to find even arguably unmeritorious claims settled for significant amounts. If any infringement or other intellectual property claim made against us by any third party is successful, if we are required to indemnify a customer with respect to a claim against the customer, or if we fail to develop non-infringing technology or license the proprietary rights on commercially reasonable terms and conditions, our business, operating results, and financial condition could be materially and adversely affected.
 
Our exposure to risks associated with the use of intellectual property may be increased as a result of acquisitions, as we have a lower level of visibility into the development process with respect to such technology or the care taken to safeguard against infringement risks. Further, in the past, third parties have made infringement and similar claims after we have acquired technology that had not been asserted prior to our acquisition.
 
We rely on the availability of third-party licenses.
 
Many of our products are designed to include software or other intellectual property licensed from third parties. It may be necessary in the future to seek or renew licenses relating to various aspects of these products. There can be no assurance that the necessary licenses would be available on acceptable terms, if at all. The inability to obtain certain licenses or other rights or to obtain such licenses or rights on favorable terms, or the
 
S-21

Table of Contents
need to engage in litigation regarding these matters, could have a material adverse effect on our business, operating results, and financial condition. Moreover, the inclusion in our products of software or other intellectual property licensed from third parties on a nonexclusive basis could limit our ability to protect our proprietary rights in our products.
 
Our operating results and future prospects could be materially harmed by uncertainties of regulation of the Internet.
 
Currently, few laws or regulations apply directly to access or commerce on the Internet. We could be materially adversely affected by regulation of the Internet and Internet commerce in any country where we operate. Such regulations could include matters such as voice over the Internet or using IP, encryption technology, sales taxes on Internet product sales, and access charges for Internet service providers. The adoption of regulation of the Internet and Internet commerce could decrease demand for our products and, at the same time, increase the cost of selling our products, which could have a material adverse effect on our business, operating results, and financial condition.
 
Changes in telecommunications regulation and tariffs could harm our prospects and future sales.
 
Changes in telecommunications requirements, or regulatory requirements in other industries in which we operate, in the United States or other countries could affect the sales of our products. In particular, we believe that there may be future changes in U.S. telecommunications regulations that could slow the expansion of the service providers’ network infrastructures and materially adversely affect our business, operating results, and financial condition.
 
Future changes in tariffs by regulatory agencies or application of tariff requirements to currently untariffed services could affect the sales of our products for certain classes of customers. Additionally, in the United States, our products must comply with various requirements and regulations of the Federal Communications Commission and other regulatory authorities. In countries outside of the United States, our products must meet various requirements of local telecommunications and other industry authorities. Changes in tariffs or failure by us to obtain timely approval of products could have a material adverse effect on our business, operating results, and financial condition.
 
Failure to retain and recruit key personnel would harm our ability to meet key objectives.
 
Our success has always depended in large part on our ability to attract and retain highly skilled technical, managerial, sales, and marketing personnel. Competition for these personnel is intense, especially in the Silicon Valley area of Northern California. Stock incentive plans are designed to reward employees for their long-term contributions and provide incentives for them to remain with us. Volatility or lack of positive performance in our stock price or equity incentive awards, or changes to our overall compensation program, including our stock incentive program, resulting from the management of share dilution and share-based compensation expense or otherwise, may also adversely affect our ability to retain key employees. As a result of one or more of these factors, we may increase our hiring in geographic areas outside the United States, which could subject us to additional geopolitical and exchange rate risk. The loss of services of any of our key personnel; the inability to retain and attract qualified personnel in the future; or delays in hiring required personnel, particularly engineering and sales personnel, could make it difficult to meet key objectives, such as timely and effective product introductions. In addition, companies in our industry whose employees accept positions with competitors frequently claim that competitors have engaged in improper hiring practices. We have received these claims in the past and may receive additional claims to this effect in the future.
 
Adverse resolution of litigation or governmental investigations may harm our operating results or financial condition.
 
We are a party to lawsuits in the normal course of our business. Litigation can be expensive, lengthy, and disruptive to normal business operations. Moreover, the results of complex legal proceedings are difficult to

predict. In addition, Brazilian authorities are investigating our Brazilian subsidiary and certain of its current and former employees, as well as a Brazilian importer of our products, and its affiliates and employees, relating to the allegation of evading import taxes and other alleged improper transactions involving the subsidiary and the importer. We are conducting a thorough review of the matter. During fiscal 2009, Brazilian authorities asserted claims against us for calendar years 2003 and 2004, and we believe claims may also be asserted for calendar year 2005 through calendar year 2007. We believe the asserted claims are without merit and intend to defend the claims vigorously. In addition, we are investigating the allegations regarding improper transactions. We have proactively communicated with United States authorities to provide information and report on our findings, and the United States authorities are currently investigating such allegations. An unfavorable resolution of lawsuits or governmental investigations could have a material adverse effect on our business, operating results, or financial condition. For additional information regarding certain of the matters in which we are involved, see Item 3, “Legal Proceedings,” contained in Part I of our Annual Report on Form 10-K for the year ended July 25, 2009.
 
Changes in our provision for income taxes or adverse outcomes resulting from examination of our income tax returns could adversely affect our results.
 
Our provision for income taxes is subject to volatility and could be adversely affected by earnings being lower than anticipated in countries that have lower tax rates and higher than anticipated in countries that have higher tax rates; by changes in the valuation of our deferred tax assets and liabilities; by expiration of or lapses in the R&D tax credit laws; by transfer pricing adjustments including the effect of acquisitions on our intercompany R&D cost sharing arrangement and legal structure; by tax effects of nondeductible compensation; by tax costs related to intercompany realignments; by changes in accounting principles; or by changes in tax laws and regulations including possible U.S. changes to the taxation of earnings of our foreign subsidiaries, and the deductibility of expenses attributable to foreign income, or the foreign tax credit rules. Significant judgment is required to determine the recognition and measurement attribute prescribed in the accounting guidance for uncertainty in income taxes. The accounting guidance for uncertainty in income taxes applies to all income tax positions, including the potential recovery of previously paid taxes, which if settled unfavorably could adversely impact our provision for income taxes or additional paid-in capital. Further, as a result of certain of our ongoing employment and capital investment actions and commitments, our income in certain countries is subject to reduced tax rates and in some cases is wholly exempt from tax. Our failure to meet these commitments could adversely impact our provision for income taxes. In addition, we are subject to the continuous examination of our income tax returns by the Internal Revenue Service and other tax authorities. We regularly assess the likelihood of adverse outcomes resulting from these examinations to determine the adequacy of our provision for income taxes. There can be no assurance that the outcomes from these continuous examinations will not have an adverse effect on our operating results and financial condition.
 
Our business and operations are especially subject to the risks of earthquakes, floods, and other natural catastrophic events.
 
Our corporate headquarters, including certain of our research and development operations are located in the Silicon Valley area of Northern California, a region known for seismic activity. Additionally, a certain number of our facilities are located near rivers that have experienced flooding in the past. A significant natural disaster, such as an earthquake, a hurricane, or a flood, could have a material adverse impact on our business, operating results, and financial condition.
 
Man-made problems such as computer viruses or terrorism may disrupt our operations and harm our operating results.
 
Despite our implementation of network security measures our servers are vulnerable to computer viruses, break-ins, and similar disruptions from unauthorized tampering with our computer systems. Any such event could have a material adverse effect on our business, operating results, and financial condition. Efforts to limit the ability of malicious third parties to disrupt the operations of the Internet or undermine our own security efforts may meet with resistance. In addition, the continued threat of terrorism and heightened security and

Table of Contents
military action in response to this threat, or any future acts of terrorism, may cause further disruptions to the economies of the United States and other countries and create further uncertainties or otherwise materially harm our business, operating results, and financial condition. Likewise, events such as widespread blackouts could have similar negative impacts. To the extent that such disruptions or uncertainties result in delays or cancellations of customer orders or the manufacture or shipment of our products, our business, operating results, and financial condition could be materially and adversely affected.
 
We are exposed to fluctuations in the market values of our portfolio investments and in interest rates; impairment of our investments could harm our earnings.
 
We maintain an investment portfolio of various holdings, types, and maturities. These securities are generally classified as available-for-sale and, consequently, are recorded on our Consolidated Balance Sheets at fair value with unrealized gains or losses reported as a component of accumulated other comprehensive income, net of tax. Our portfolio includes fixed income securities and equity investments in publicly traded companies, the values of which are subject to market price volatility to the extent unhedged. If such investments suffer market price declines, as we experienced with some of our investments during the first quarter of fiscal 2009, we may recognize in earnings the decline in the fair value of our investments below their cost basis when the decline is judged to be other than temporary. For information regarding the sensitivity of and risks associated with the market value of portfolio investments and interest rates, refer to the section titled “Quantitative and Qualitative Disclosures About Market Risk” included in our 2009 Annual Report to Shareholders. Our investments in private companies are subject to risk of loss of investment capital. These investments are inherently risky because the markets for the technologies or products they have under development are typically in the early stages and may never materialize. We could lose our entire investment in these companies.
 
If we do not successfully manage our strategic alliances, we may not realize the expected benefits from such alliances and we may experience increased competition or delays in product development.
 
We have several strategic alliances with large and complex organizations and other companies with which we work to offer complementary products and services and are in the process of establishing a joint venture to market services associated with our UCS products. These arrangements are generally limited to specific projects, the goal of which is generally to facilitate product compatibility and adoption of industry standards. There can be no assurance we will realize the expected benefits from these strategic alliances or from the joint venture. If successful, these relationships may be mutually beneficial and result in industry growth. However, alliances carry an element of risk because, in most cases, we must compete in some business areas with a company with which we have a strategic alliance and, at the same time, cooperate with that company in other business areas. Also, if these companies fail to perform or if these relationships fail to materialize as expected, we could suffer delays in product development or other operational difficulties. Joint ventures can be difficult to manage, given the potentially different interests of joint venture partners.
 
Our stock price may be volatile.
 
Historically, our common stock has experienced substantial price volatility, particularly as a result of variations between our actual financial results and the published expectations of analysts and as a result of announcements by our competitors and us. Furthermore, speculation in the press or investment community about our strategic position, financial condition, results of operations, business, security of our products, or significant transactions can cause changes in our stock price. In addition, the stock market has experienced extreme price and volume fluctuations that have affected the market price of many technology companies, in particular, and that have often been unrelated to the operating performance of these companies. These factors, as well as general economic and political conditions and the announcement of proposed and completed acquisitions or other significant transactions, or any difficulties associated with such transactions, by us or our current or potential competitors, may materially adversely affect the market price of our common stock in the future. Additionally, volatility, lack of positive performance in our stock price or changes to our overall compensation program including our stock incentive program may adversely affect our ability to retain key employees, virtually all of whom are compensated, in part, based on the performance of our stock price.

Risks Related to the Offering
 
The notes are structurally subordinated to the liabilities of our subsidiaries.
 
The notes are our obligations exclusively and not of any of our subsidiaries. A significant portion of our operations is conducted through our subsidiaries. Our subsidiaries are separate legal entities that have no obligation to pay any amounts due under the notes or to make any funds available therefor, whether by dividends, loans or other payments. Except to the extent we are a creditor with recognized claims against our subsidiaries, all claims of creditors (including trade creditors) and holders of preferred stock, if any, of our subsidiaries will have priority with respect to the assets of such subsidiaries over our claims (and therefore the claims of our creditors, including holders of the notes). Consequently, the notes will be effectively subordinated to all liabilities of any of our subsidiaries and any subsidiaries that we may in the future acquire or establish. As of July 25, 2009, our subsidiaries had approximately $3.8 billion of outstanding liabilities, including trade payables but excluding intercompany liabilities and deferred revenue.
 
The notes are subject to prior claims of any secured creditors, and if a default occurs, we may not have sufficient funds to fulfill our obligations under the notes.
 
The notes are our unsecured general obligations, ranking equally with other senior unsecured indebtedness, including previously issued notes. The indenture governing the notes permits us and our subsidiaries to incur additional, secured debt under specified circumstances. If we incur any secured debt, our assets and the assets of our subsidiaries will be subject to prior claims by our secured creditors. In the event of our bankruptcy, liquidation, reorganization or other winding up, assets that secure debt will be available to pay obligations on the notes only after all debt secured by those assets has been repaid in full. Holders of the notes will participate in our remaining assets ratably with all of our unsecured and unsubordinated creditors, including our trade creditors. If we incur any additional obligations that rank equally with the notes, including trade payables, the holders of those obligations will be entitled to share ratably with the holders of the notes and the previously issued notes in any proceeds distributed upon our insolvency, liquidation, reorganization, dissolution or other winding up. This may have the effect of reducing the amount of proceeds paid to you. If there are not sufficient assets remaining to pay all these creditors, all or a portion of the notes then outstanding would remain unpaid.
 
Negative covenants in the indenture will have a limited effect.
 
The indenture governing the notes contains only limited negative covenants that apply to us and our subsidiaries. These covenants do not limit the amount of additional debt that we may incur. In addition, the limitation on liens and limitation on sale and lease-back covenants contain exceptions that will, subject to certain limitations, allow us and our subsidiaries to create, grant or incur liens or security interests with respect to our headquarters and certain other material facilities. You should read “ Description of Debt Securities—Covenants ” in the accompanying prospectus for a description of these covenants. In light of these exceptions, holders of the notes may be structurally or contractually subordinated to new lenders.
 
Changes in our credit ratings may adversely affect your investment in the notes.
 
The major debt rating agencies routinely evaluate our debt. These ratings are not recommendations to purchase, hold or sell the notes, inasmuch as the ratings do not comment as to market price or suitability for a particular investor, are limited in scope, and do not address all material risks relating to an investment in the notes, but rather reflect only the view of each rating agency at the time the rating is issued. The ratings are based on current information furnished to the ratings agencies by us and information obtained by the ratings agencies from other sources. An explanation of the significance of such rating may be obtained from such rating agency. There can be no assurance that such credit ratings will remain in effect for any given period of time or that such ratings will not be lowered, suspended or withdrawn entirely by the rating agencies, if, in each rating agency’s
 
S-25

Table of Contents
judgment, circumstances so warrant. Actual or anticipated changes or downgrades in our credit ratings, including any announcement that our ratings are under further review for a downgrade, could affect the market value and liquidity of the notes and increase our corporate borrowing costs.
 
There may not be active trading markets for the notes.
 
There is no existing market for any series of the notes and we do not intend to apply for listing of the notes on any securities exchange or any automated quotation system. Accordingly, there can be no assurance that trading markets for the notes will ever develop or will be maintained. Further, there can be no assurance as to the liquidity of any market that may develop for the notes, your ability to sell your notes or the prices at which you will be able to sell your notes. Future trading prices of the notes will depend on many factors, including prevailing interest rates, our financial condition and results of operations, the then-current ratings assigned to the notes and the market for similar securities. Any trading markets that develop would be affected by many factors independent of and in addition to the foregoing, including:
 
 	Ÿ	 	time remaining to the maturity of the notes	
 
 	Ÿ	 	outstanding amount of the notes	
 
 	Ÿ	 	the terms related to optional redemption of the notes	
 
 	Ÿ	 	the level, direction and volatility of market interest rates generally	
 
There can be no assurance that our operating results and financial condition will not be adversely affected by our incurrence of senior unsecured debt.
 
We have issued senior unsecured notes in an aggregate principal amount of $10.5 billion (the “previously issued notes”), of which $500 million matured and was paid in full on February 20, 2009 and the balance will mature at specific dates in 2011, 2016, 2019 and 2039. The outstanding previously issued notes bear fixed-rate interest payable semi-annually. In addition, the amount of our long-term debt will increase by the principal amount of the notes sold in this offering. The fair value of the long-term debt is subject to market interest rate volatility. The instruments governing the previously issued notes and the notes sold in this offering contain certain covenants applicable to us and our subsidiaries that may adversely affect our ability to incur certain liens or engage in certain types of sale and leaseback transactions. We cannot assure you that the indebtedness represented by the notes, in addition to our other indebtedness, will not adversely affect our operating results or financial condition.

The 2.90% Senior Notes due 2014 (the “2014 notes”), the 4.45% Senior Notes due 2020 (the “2020 notes”) and the 5.50% Senior Notes due 2040 (the “2040 notes”) will be issued as separate series of debt securities under an indenture to be entered into on or about November 17, 2009 between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). The 2014 notes will mature on November 17, 2014, the 2020 notes will mature on January 15, 2020 and the 2040 notes will mature on January 15, 2040.
 
Unless previously redeemed or purchased and cancelled, we will repay the notes in cash at 100% of their principal amount together with accrued and unpaid interest thereon at maturity. We will pay principal of and interest on the notes in U.S. dollars.
 
The notes will be our senior unsecured debt obligations and will rank equally among themselves and with all of our other present and future senior unsecured indebtedness.
 
The 2014 notes, the 2020 notes and the 2040 notes will be redeemable by us at any time prior to maturity as described below under “—Optional Redemption.”
 
The notes will be issued in registered, book-entry form only without interest coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.
 
The notes will not be subject to a sinking fund. The notes will be subject to defeasance as described in the accompanying prospectus.
 
The indenture and the notes do not limit the amount of indebtedness which may be incurred or the amount of securities which may be issued by us or our subsidiaries, and contain no financial or similar restrictions on us or our subsidiaries, except as described under “Description of Debt Securities—Covenants” in the accompanying prospectus.
 
The notes will be issued in an aggregate initial principal amount of $500,000,000 in the case of the 2014 notes, $2,500,000,000 in the case of the 2020 notes and $2,000,000,000 in the case of the 2040 notes, subject to our ability to issue additional notes of any series which may be of that same series as described under “Description of Debt Securities—Further Issues,” in the accompanying prospectus.
 
If the scheduled maturity date or redemption date for the notes of any series falls on a day that is not a business day, the payment of interest and principal will be made on the next succeeding business day, and no interest on such payment shall accrue for the period from and after the scheduled maturity date or redemption date, as the case may be.
 
Interest
 
The 2014 notes will bear interest at a rate of 2.90% per annum, the 2020 notes will bear interest at a rate of 4.45% per annum and the 2040 notes will bear interest at a rate of 5.50% per annum. Interest on the 2014 notes, the 2020 notes and the 2040 notes will accrue from November 17, 2009, or from the most recent interest payment date to which interest has been paid or provided for, to but excluding the relevant interest payment date. We will make interest payments on the 2014 notes semiannually in arrears on May 17 and November 17 of each year, beginning on May 17, 2010, to the person in whose name such notes are registered at the close of business on the immediately preceding May 1 and November 1, as applicable. We will make interest payments on the 2020 notes and 2040 notes semiannually in arrears on January 15 and July 15 of each year,
 
S-30

Table of Contents
beginning on January 15, 2010, to the person in whose name such notes are registered at the close of business on the immediately preceding January 1 or July 1, as applicable. Interest on the notes will be computed on the basis of a 360-day year of twelve 30-day months.
 
If an interest payment date falls on a day that is not a business day, the interest payment shall be made on the next succeeding business day, and no interest on such payment shall accrue for the period from and after such interest payment date.
 
Optional Redemption
 
The notes of each series are redeemable, as a whole or in part, at our option, at any time or from time to time, upon notice mailed to the registered address of each holder of notes at least 30 days but not more than 60 days prior to the date of redemption. The “make-whole premium” redemption price will be equal to the greater of (1) 100% of the principal amount of the notes to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments (as defined below) on such notes discounted to the date of redemption, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the sum of the applicable Treasury Rate (as defined below) plus 10 basis points with respect to the 2014 notes, 15 basis points with respect to the 2020 notes and 20 basis points with respect to the 2040 notes. Accrued interest will be paid to but excluding the redemption date.
 
“Treasury Rate” means, with respect to any redemption date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the third business day immediately preceding that redemption date) of the Comparable Treasury Issue (as defined below), assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price (as defined below) for that redemption date.
 
“Comparable Treasury Issue” means the United States Treasury security selected by a Reference Treasury Dealer (as defined below) as selected by us as having an actual or interpolated maturity comparable to the remaining term of the notes called for redemption, that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of notes called for redemption.
 
“Comparable Treasury Price” means, with respect to any redemption date, the average, as determined by us, of the Reference Treasury Dealer Quotations (as defined below) for that redemption date.
 
“Reference Treasury Dealer” means Barclays Capital Inc., Credit Suisse Securities (USA) LLC and Deutsche Bank Securities Inc. and one other primary U.S. Government securities dealer selected by us, and each of their respective successors. If it shall cease to be a primary U.S. Government securities dealer, we will substitute another nationally recognized investment banking firm that is a primary U.S. Government securities dealer.
 
“Reference Treasury Dealer Quotations” means, on any redemption date, the average, as determined by us, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us by the Reference Treasury Dealer at 3:30 p.m., New York City time, on the third business day preceding that redemption date.
 
“Remaining Scheduled Payments” means the remaining scheduled payments of principal of and interest on the notes called for redemption that would be due after the related redemption date but for that redemption. If that redemption date is not an interest payment date with respect to the notes called for redemption, the amount of the next succeeding scheduled interest payment on such notes will be reduced by the amount of interest accrued to such redemption date.
 
S-31

Table of Contents
We will prepare and mail a notice of redemption to each holder of notes to be redeemed by first-class mail at least 30 and not more than 60 days prior to the date fixed for redemption. On and after a redemption date, interest will cease to accrue on the notes called for redemption (unless we default in the payment of the redemption price and accrued interest). On or before a redemption date, we will deposit with a paying agent (or the Trustee) money sufficient to pay the redemption price of and accrued interest on the notes to be redeemed on that date. If less than all of the notes are to be redeemed, the notes to be redeemed shall be selected by the Trustee pro rata or by lot or by a method the Trustee deems to be fair and appropriate.

 MATERIAL UNITED STATES INCOME TAX CONSIDERATIONS
 
The following discussion summarizes the material U.S. federal income tax considerations that may be relevant to you if you invest in the notes. Except as discussed under “ —Non-U.S. holders ” and “ —Information reporting and backup withholding ” below, the discussion generally applies only to holders of notes that are U.S. holders. You will be a U.S. holder if you are (i) an individual who is a citizen or resident of the United States for U.S. federal income tax purposes; (ii) a corporation (or other entity taxable as a corporation) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; (iii) an estate, the income of which is subject to U.S. federal income taxation regardless of its source; or (iv) a trust if (A) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (B) the trust has in effect a valid election in effect under applicable Treasury Regulations to be treated as a United States person for U.S. federal income tax purposes. A “non-U.S. holder” is a beneficial owner of a note that is not a U.S. holder.
 
This summary applies only to notes that are held: (i) as capital assets (generally, property held for investment) and (ii) by those holders who purchased notes on original issuance at the “issue price” (generally, the first price at which a substantial portion of the notes is sold for cash to the public (not including bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers)). This summary does not address all of the considerations that may be relevant to you if you are an investor that is subject to special tax rules, such as a bank, thrift, real estate investment trust, regulated investment company, insurance company, dealer in securities or currencies, trader in securities or commodities that elects mark to market treatment, person that will hold notes as a position in a “straddle,” conversion, integrated transaction or other similar transaction, tax-exempt organization, partnership or other entity classified as a partnership for U.S. federal income tax purposes, a former citizen or resident of the United States, a person who is liable for the alternative minimum tax, or a U.S. holder whose “functional currency” is not the U.S. dollar. If an entity that is treated as a partnership for U.S. federal income tax purposes holds the notes, the tax treatment of a partner generally will depend on the status of the partner and the activities of the partnership. If you are a partner in such an entity, you should consult your tax advisor as to the U.S. federal income tax consequences of holding notes. In addition, this discussion does not describe any tax consequences arising out of the tax laws of any state, local or foreign jurisdiction, or any possible applicability of U.S. federal gift or estate tax.
 
This summary is based on the provisions of the Internal Revenue Code of 1986, as amended, (the “Code”), and the U.S. federal income tax regulations promulgated under the Code (the “Treasury Regulations”), rulings and judicial decisions thereunder as of the date hereof, all of which may change. Any change could apply retroactively and could affect the continued validity of this summary.
 
You should consult your tax advisor about the tax consequences of purchasing or holding notes, including the relevance to your particular situation of the considerations discussed below, as well as the relevance to your particular situation of state, local, foreign or other tax laws.
 
Payments or accruals of interest
 
Payments or accruals of interest on a note will be taxable to you as ordinary income at the time that you actually or constructively receive or accrue such amounts (in accordance with your regular method of tax accounting).
 
Repurchase options
 
We may redeem the notes, in whole or in part, at our option (see “ Description of Notes—Optional Redemption ”). If the amount or timing of any payment on a note is contingent, the note could be subject to special rules that apply to “contingent payment debt instruments.” The optional redemption provision should not cause a note to be treated as creating a “contingent payment debt instrument” for purposes of the original issue discount provisions of the Code.

Sale, exchange, redemption and retirement of notes
 
When you sell or exchange a note, or if a note that you hold is retired or redeemed, you generally will recognize taxable gain or loss equal to the difference between the amount you realize on the transaction (less any accrued interest, which will be subject to tax in the manner described above under “ —Payments or accruals of interest ”) and your tax basis in the note. Initially, your tax basis in a note generally will equal the amount you paid for the note.
 
The gain or loss that you recognize on the sale, exchange, redemption or retirement of a note generally will be capital gain or loss. The capital gain or loss on the sale, exchange, redemption or retirement of a note will be long-term capital gain or loss if you have held the note for more than one year on the date of disposition. Net long-term capital gain recognized by an individual U.S. holder generally is subject to tax at a lower rate than net short-term capital gain or ordinary income. The ability of U.S. holders to offset capital losses against ordinary income is limited.
 
Non-U.S. holders
 
For purposes of the discussion below, interest and gain on the sale, redemption or repayment of notes will be considered to be “U.S. trade or business income” if such income or gain is (i) effectively connected with the non-U.S. holder’s conduct of a U.S. trade or business and (ii) in the case of a non-U.S. holder eligible for the benefits of a bilateral income tax treaty to which the United States is a party, attributable to a U.S. permanent establishment (or, in the case of an individual, a fixed base) in the United States.
 
Subject to the discussion below regarding backup withholding, interest paid on the notes to a non-U.S. holder generally will not be subject to U.S. federal income or withholding tax if such interest is not U.S. trade or business income and is “portfolio interest.” Generally, interest on the notes will qualify as portfolio interest if the non-U.S. holder:
 
 	(i)	 	does not actually or constructively own 10% or more of the total combined voting power of all classes of our stock entitled to vote,	
 
 	(ii)	 	is not a controlled foreign corporation (in general, a foreign corporation is a controlled foreign corporation if more than 50% of its stock, by voting power or value, is owned, actually or constructively, by one or more U.S. persons that each owns, actually or constructively, at least 10% of the corporation’s voting power) with respect to which we are a “related person” within the meaning of the Code,	
 
 	(iii)	 	is not a bank that is receiving the interest on a loan made in the ordinary course of its trade or business, and	
 
 	(iv)	 	either (a) certifies, under penalties of perjury on a Form W-8BEN (or such successor form as the IRS designates), prior to the payment that such holder is not a U.S. person and provides such holder’s name and address, or (b) holds the note through certain foreign intermediaries or certain foreign partnerships and satisfies the certification requirements under the applicable Treasury Regulations.	
 
The gross amount of payments of interest that do not qualify as portfolio interest and that are not U.S. trade or business income will be subject to U.S. withholding tax at a rate of 30% unless an applicable treaty applies to reduce or eliminate withholding. U.S. trade or business income will be taxed at regular, graduated U.S. rates (as if earned by a U.S. holder) rather than the 30% gross withholding tax rate. In the case of a non-U.S. holder that is a corporation, such U.S. trade or business income may also be subject to the branch profits tax equal to 30% (or a lower rate under an applicable income tax treaty) on the non-U.S. holder’s earnings and profits for the taxable year, subject to adjustments.
 
To claim the benefits of a treaty exemption from or reduction in withholding, a non-U.S. holder must, prior to the payment of interest, provide a properly executed Form W-8BEN (or such successor form as the IRS
 
S-34

Table of Contents
designates). To claim an exemption from withholding because income is U.S. trade or business income, a non-U.S. holder must, prior to the payment of interest, provide a properly executed Form W-8ECI (or such successor form as the IRS designates). These forms may need to be periodically updated. A non-U.S. holder that is claiming the benefits of a treaty may be required in certain instances to obtain a U.S. taxpayer identification number (“TIN”) and to provide it on a Form W-8BEN.
 
Subject to the discussion below concerning backup withholding, if you are a non-U.S. holder, any gain you realize on a sale, exchange, redemption or other disposition of notes generally will be exempt from U.S. federal income tax, including withholding tax. This exemption will not apply to you if (i) the gain is U.S. trade or business income, in which case the branch profits tax may also apply if you are a corporate non-U.S. holder; or (ii) you are an individual who is present in the United States for 183 or more days in the taxable year of the disposition and certain other requirements are met.
 
Special rules may apply to certain non-U.S. holders (or their beneficial owners), such as “controlled foreign corporations,” “passive foreign investment companies,” and certain expatriates, that are subject to special treatment under the Code. Such non-U.S. holders (or their beneficial owners) should consult their own tax advisors to determine the U.S. federal, state, local and other tax consequences that may be relevant to them.
 
Information reporting and backup withholding
 
If you are a U.S. holder, you will generally be subject to information reporting and may also be subject to backup withholding, currently at a rate of 28%, when you receive interest payments on a note or proceeds upon the sale or other disposition of a note. Certain U.S. holders (including, among others, corporations) are generally not subject to information reporting or backup withholding. In addition, backup withholding will not apply if you provide your TIN to the payor in the prescribed manner unless: (A) the IRS notifies us or our agent that the TIN you provided is incorrect; (B) you fail to report interest and dividend payments that you receive on your tax return and the IRS notifies us or our agent that withholding is required; or (C) you fail to certify under penalties of perjury that (i) you provided to us with your correct TIN, (ii) you are not subject to backup withholding, and (iii) you are a U.S. person (including a U.S. resident alien).
 
Information returns will be filed with the IRS in connection with payments on the notes to non-U.S. holders. If you are a non-U.S. holder, you may have to comply with certification procedures to establish your non-U.S. status in order to avoid additional information reporting and backup withholding tax requirements. The certification procedures required to claim the exemption from withholding tax on interest income described above will satisfy these certification requirements.
 
The amount of any backup withholding from a payment to a holder may be allowed as a credit against the holder’s U.S. federal income tax liability and may entitle the holder to a refund, provided that the required information is timely furnished to the IRS.
 
THE PRECEDING DISCUSSION OF FEDERAL INCOME TAX CONSEQUENCES IS FOR GENERAL INFORMATION ONLY AND IS NOT TAX ADVICE. ACCORDINGLY, EACH INVESTOR SHOULD CONSULT HIS, HER OR ITS OWN TAX ADVISOR AS TO PARTICULAR TAX CONSEQUENCES TO HIM, HER OR IT OF PURCHASING, HOLDING AND DISPOSING OF NOTES, INCLUDING THE APPLICABILITY AND EFFECT OF ANY STATE, LOCAL OR FOREIGN TAX LAWS, AND OF ANY PROPOSED CHANGES IN APPLICABLE LAW.

The underwriters are offering the notes subject to their receipt and acceptance of the notes from us, to their right to reject any order in whole or in part and to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the notes offered by this prospectus supplement are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the notes offered by this prospectus supplement if any such notes are taken.
 
The underwriters initially propose to offer part of the notes of each series directly to the public at the offering prices described on the cover page of this prospectus supplement. In addition, the underwriters initially propose to offer part of the 2014 notes to certain dealers at a price that represents a concession not in excess of 0.20% of the principal amount of the 2014 notes, part of the 2020 notes to certain dealers at a price that represents a concession not in excess of 0.30% of the principal amount of the 2020 notes and part of the 2040 notes to certain dealers at a price that represents a concession not in excess of 0.45% of the principal amount of the 2040 notes. Any underwriter may allow, and any such dealer may reallow, a concession not in excess of 0.075% of the principal amount of the 2014 notes, 0.125% of the principal amount of the 2020 notes and 0.25% of the principal amount of the 2040 notes to certain other dealers. After the initial offering of the notes, the underwriters may from time to time vary the offering prices and other selling terms.
 
The following table shows the underwriting discounts that we will pay to the underwriters in connection with this offering:

 	  	Paid By Us	 	
Per 2014 note	  	 	0.35	% 	
Per 2020 note	  	 	0.45	%

We have also agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, or to contribute to payments which the underwriters may be required to make in respect of any such liabilities.
 
In connection with the offering of the notes, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the prices of the notes. Specifically, the underwriters may overallot in connection with the offering of the notes, creating a syndicate short position. In addition, the underwriters may bid for, and purchase, notes in the open market to cover syndicate short positions or to stabilize the prices of the notes. Finally, the underwriting syndicate may reclaim selling concessions allowed for distributing the notes in the offering of the notes, if the syndicate repurchases previously distributed notes in syndicate covering transactions, stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market prices of the notes above independent market levels. The underwriters are not required to engage in any of these activities, and may end any of them at any time.
 
Expenses associated with this offering to be paid by us, other than underwriting discounts, are estimated to be $900,000. The underwriters have agreed to reimburse us for certain of our out-of-pocket expenses in connection with this offering.
 
We expect to deliver the notes against payment therefor on or about the date specified in the last paragraph of the cover page of this prospectus supplement, which will be the fifth business day following the date of the pricing of the notes. Under Rule 15c6-1 of the Exchange Act, trades in the secondary market are required to settle in three business days, unless the parties to a trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the date of pricing or the next succeeding business day will be required, by virtue of the fact that the notes initially will settle in T+5, to specify alternative settlement arrangements to prevent a failed settlement.
 
From time to time in the ordinary course of their respective businesses, certain of the underwriters and their affiliates have engaged in and may in the future engage in commercial banking, derivatives and/or investment banking transactions with us and our affiliates. Affiliates of the underwriters are lenders under our revolving credit facility, for which these affiliates have been and will be paid customary fees. In addition, Richard M. Kovacevich, one of our directors, is the Chairman of Wells Fargo & Company. Wells Fargo & Company is the parent of Wells Fargo Securities, LLC, one of the senior co-managers of this offering.
 
Standard Chartered Bank is not a U.S.-registered broker-dealer and, therefore, to the extent that it intends to effect any sales of the notes in the United States, it will do so through one or more U.S.-registered broker-dealers as permitted by FINRA regulations.
 
European Economic Area
 
In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive, each underwriter has represented and agreed that with effect from and including the date on which the Prospectus Directive is implemented in that Member State it has not made and will not make an offer of notes to the public in that Member State, except that it may, with effect from and including such date, make an offer of notes to the public in that Member State:
 
 	Ÿ	 	at any time to legal entities which are authorised or regulated to operate in the financial markets or, if not so authorised or regulated, whose corporate purpose is solely to invest in securities;	
 
 	Ÿ	 	at any time to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000; and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts;

 	Ÿ	 	to fewer than 100 natural or legal persons (other than qualified investors as defined in the Prospectus Directive) subject to obtaining the prior consent of the representatives for any such offer; or	
 
 	Ÿ	 	at any time in any other circumstances which do not require the publication by us of a prospectus pursuant to Article 3 of the Prospectus Directive.	
 
For the purposes of the above, the expression an “offer of notes to the public” in relation to any notes in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the notes to be offered so as to enable an investor to decide to purchase or subscribe the notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State and the expression Prospectus Directive means Directive 2003/71/EC and includes any relevant implementing measure in that Member State.
 
United Kingdom
 
Each underwriter has represented and agreed that it has only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000) in connection with the issue or sale of the notes in circumstances in which Section 21(1) of such Act does not apply to us and it has complied and will comply with all applicable provisions of such Act with respect to anything done by it in relation to any notes in, from or otherwise involving the United Kingdom.
 
 LEGAL MATTERS
 
Fenwick & West LLP, Mountain View, California, will pass upon the authorization and validity of the securities. Davis Polk & Wardwell LLP, Menlo Park, California, is representing the underwriters. As of November 6, 2009, attorneys of Fenwick & West LLP beneficially owned an aggregate of approximately 225,000 shares of our common stock.

 RATIO OF EARNINGS TO FIXED CHARGES
 
The following table contains our ratio of earnings to fixed charges for the periods indicated.

For purposes of determining the ratio of earnings to fixed charges, “earnings” represent earnings before income taxes, minority interest and cumulative effect of accounting changes. “Fixed charges” represent interest expense plus that portion of rent expense that, in our opinion, approximates the interest component of rental expense.

 DESCRIPTION OF DEBT SECURITIES
 
General
 
The debt securities offered by this prospectus will be issued under an indenture between us and The Bank of New York Mellon Trust Company, N.A., as trustee (the “Trustee”). We have filed the form of indenture as an exhibit to the registration statement of which this prospectus is a part. We have summarized selected provisions of the indenture and the debt securities below. This summary is not complete and is qualified in its entirety by reference to the indenture.
 
We may issue debt securities at any time and from time to time, in one or more series, under the indenture. We will describe the particular terms of each series of debt securities we offer in a supplement to this prospectus. If any particular terms of the debt securities described in a prospectus supplement differ from any of the terms described in this prospectus, then the terms described in the applicable prospectus supplement will supersede the terms described in this prospectus. The terms of our debt securities will include those set forth in the indenture and those made a part of the indenture by the Trust Indenture Act of 1939, as amended. You should carefully read the summary below, the applicable prospectus supplement and the provisions of the indenture that may be important to you before investing in our debt securities.
 
Ranking
 
The debt securities offered by this prospectus will:
 
 	Ÿ	 	be our senior unsecured obligations;	
 
 	Ÿ	 	rank equally with all of our other unsecured and unsubordinated indebtedness; and	
 
 	Ÿ	 	with respect to the assets and earnings of our subsidiaries, effectively rank below all of the liabilities of our subsidiaries.	
 
The indenture does not limit the amount of debt securities or other unsecured debt which we or our subsidiaries may issue. A significant portion of our assets are owned through our subsidiaries, many of which have significant liabilities of their own which will be structurally senior to the debt securities. None of our subsidiaries will have any obligations with respect to the debt securities. Therefore, our rights and the rights of our creditors, including holders of debt securities, to participate in the distribution of the assets of any subsidiary upon any such subsidiary’s liquidation may be subject to the prior claims of the subsidiary’s other creditors.
 
Subject to exceptions, and subject to compliance with the applicable requirements set forth in the indenture, we may discharge our obligations under the indenture with respect to our debt securities as described below under “— Defeasance .”
 
Further Issues
 
Subject to the limitations contained in the indenture, we may from time to time, without notice to or the consent of the registered holders of a series of debt securities, create and issue further debt securities of any such series ranking equally with the debt securities of the corresponding series in all respects (or in all respects other than the payment of interest accruing prior to the issue date of such further debt securities or except, in some cases, for the first payment of interest following the issue date of such further debt securities). Such further debt securities may be consolidated and form a single series with the debt securities of the corresponding series and have the same terms as to status, redemption or otherwise as the debt securities of the corresponding series.

 	Ÿ	 	any provisions for redemption of the debt securities;	
 
 	Ÿ	 	any provisions that would allow or obligate us to redeem or purchase the debt securities prior to their maturity pursuant to any sinking fund or analogous provision or at the option of the holder;

 	Ÿ	 	any provisions that would determine payments on the debt securities by reference to an index or a formula;	
 
 	Ÿ	 	any foreign currency, currencies or currency units in which payments on the debt securities will be payable and the manner for determining the equivalent amount in U.S. dollars;	
 
 	Ÿ	 	any provisions for payments on the debt securities in one or more currencies or currency units other than those in which the debt securities are stated to be payable;

 	Ÿ	 	if the principal amount to be paid at the stated maturity of the debt securities is not determinable as of one or more dates prior to the stated maturity, the amount that will be deemed to be the principal amount as of any such date for any purpose;	
 
 	Ÿ	 	any additional provisions relating to defeasance of the debt securities;	
 
 	Ÿ	 	whether we will issue the debt securities in the form of global securities or certificates, the depositories for global securities and provisions for exchanging or transferring debt securities;	
 
 	Ÿ	 	whether the interest rate of the debt securities may be reset;

5

Table of Contents

 	Ÿ	 	any other terms of the debt securities consistent with the indenture.	
 
Any limit on the maximum total principal amount for any series of the debt securities may be increased by resolution of our board of directors. We may sell the debt securities, including original issue discount securities, at a substantial discount below their stated principal amount. If there are any special United States federal income tax considerations applicable to debt securities we sell at an original issue discount, we will describe them in a prospectus supplement. In addition, we will describe in the prospectus supplement any special United States federal income tax considerations and any other special considerations for any debt securities we sell which are denominated in a currency or currency unit other than U.S. dollars.
 
Exchange and Transfer
 
Holders generally will be able to exchange debt securities for other debt securities of the same series with the same total principal amount and the same terms but in different authorized denominations.
 
Holders may present debt securities for exchange or for registration of transfer at the office of the security registrar or at the office of any transfer agent we designate for that purpose. The security registrar or designated transfer agent will exchange or transfer the debt securities if it is satisfied with the documents of title and identity of the person making the request. We will not charge a service charge for any exchange or registration of transfer of debt securities. However, we and the security registrar may require payment of a sum sufficient to cover any tax or other governmental charge payable for the registration of transfer or exchange. Unless we inform you otherwise in the prospectus supplement, we will appoint the Trustee as security registrar. We will identify any transfer agent in addition to the security registrar in the prospectus supplement. At any time we may:
 
 	Ÿ	 	designate additional transfer agents;	
 
 	Ÿ	 	rescind the designation of any transfer agent; or	
 
 	Ÿ	 	approve a change in the office of any transfer agent.	
 
However, we are required to maintain a transfer agent in each place of payment for the debt securities at all times. If we elect to redeem a series of debt securities, neither we nor the Trustee will be required to:
 
 	Ÿ	 	issue, register the transfer of or exchange any debt securities of that series during the period beginning at the opening of business 15 days before the day we mail the notice of redemption for the series and ending at the close of business on the day the notice is mailed; or	
 
 	Ÿ	 	register the transfer or exchange of any debt security of that series so selected for redemption, except for any portion not to be redeemed.	
 
Payment and Paying Agents
 
Under the indenture, we will pay interest on the debt securities to the persons in whose names the debt securities are registered at the close of business on the regular record date for each interest payment. However, unless we inform you otherwise in the prospectus supplement, we will pay the interest payable on the debt securities at their stated maturity to the persons to whom we pay the principal amount of the debt securities. The initial payment of interest on any series of debt securities issued between a regular record date and the related interest payment date will be payable in the manner provided by the terms of the series, which we will describe in the prospectus supplement.

Table of Contents
Unless we inform you otherwise in the prospectus supplement, we will pay principal, premium, if any, and interest on the debt securities at the offices of the paying agents we designate. However, except in the case of a global security, we will pay interest by:
 
 	Ÿ	 	check mailed to the address of the person entitled to the payment as it appears in the security register; or	
 
 	Ÿ	 	if you are a holder with an aggregate principal amount in excess of $2.0 million, by wire transfer in immediately available funds to the place and account designated in writing at least fifteen days prior to the interest payment date by the person entitled to the payment as specified in the security register.	
 
We will designate the Trustee as the sole paying agent for the debt securities unless we inform you otherwise in the prospectus supplement. If we initially designate any other paying agents for a series of debt securities, we will identify them in the prospectus supplement. At any time, we may designate additional paying agents or rescind the designation of any paying agents. However, we are required to maintain a paying agent in each place of payment for the debt securities at all times.
 
Any money deposited with the Trustee or any paying agent for the payment of principal, premium, if any, and interest on the debt securities that remains unclaimed for two years after the date the payments became due, may be repaid to us upon our request. After we have been repaid, holders entitled to those payments may only look to us for payment as our unsecured general creditors. The Trustee and any paying agents will not be liable for those payments after we have been repaid.
 
Covenants
 
The indenture contains covenants including, among others, the following:
 
Consolidation, Merger and Conveyance, Transfer and Lease of Assets
 
We may not consolidate with or merge into, or convey, transfer or lease our properties and assets substantially as an entirety to, any person, referred to as a “successor person” unless:
 
 	Ÿ	 	either (a) we are the continuing person or (b) the resulting, surviving or transferee person is an entity organized under the laws of the United States;	
 
 	Ÿ	 	the successor person expressly assumes our obligations with respect to the debt securities and the indenture;	
 
 	Ÿ	 	immediately after giving effect to the transaction, no event of default, and no event which, after notice or lapse of time or both, would become an event of default, shall have occurred and be continuing; and	
 
 	Ÿ	 	we or the successor person have delivered to the Trustee the certificates and opinions required under the indenture.	
 
Limitation on Liens
 
Neither we nor any of our wholly-owned subsidiaries will create or incur any Lien on any Principal Property, whether now owned or hereafter acquired, in order to secure any Indebtedness, without effectively providing that the notes shall be equally and ratably secured until such time as such Indebtedness is no longer secured by such Lien, except:
 
 	Ÿ	 	Liens existing as of the closing date of the offering of the notes;	
 
 	Ÿ	 	Liens granted after the closing date of the offering of the notes created in favor of the holders of the notes;

Table of Contents

 	Ÿ	 	Liens securing Indebtedness which are incurred to extend, renew or refinance Indebtedness which is secured by Liens permitted to be incurred under the Indenture.	
 
 	Ÿ	 	Liens created in substitution of or as replacements for any Liens described in the preceding three bullet points; provided that based on a good faith determination of one of our Senior Officers, the Principal Property encumbered under any such substitute or replacement Lien is substantially similar in nature to the Principal Property encumbered by the otherwise permitted Lien which is being replaced; and	
 
 	Ÿ	 	Permitted Liens.	
 
Notwithstanding the foregoing, we may, without equally and ratably securing the notes, create or incur Liens which would otherwise be subject to the restrictions set forth in the preceding paragraph, if after giving effect thereto, Aggregate Debt does not exceed the greater of (i) 15% of Consolidated Net Worth calculated as of the date of the creation or incurrence of the Lien or (ii) 15% of Consolidated Net Worth calculated as of the date of the issuance of the notes.
 
Limitation on Sale and Lease-Back Transactions
 
Neither we nor any of our wholly-owned subsidiaries will enter into any sale and lease-back transaction for the sale and leasing back of any Principal Property, whether now owned or hereafter acquired, unless:
 
 	Ÿ	 	such transaction was entered into prior to the closing date of the offering of the notes;	
 
 	Ÿ	 	such transaction was for the sale and leasing back to us of any Principal Property by one of our subsidiaries;	
 
 	Ÿ	 	such transaction involves a lease for not more than three years (or which may be terminated by us within a period of not more than three years);	
 
 	Ÿ	 	we would be entitled to incur Indebtedness secured by a mortgage on the property to be leased in an amount equal to Attributable Liens with respect to such sale and lease-back transaction without equally and ratably securing the notes pursuant to the first paragraph of “—Limitation on Liens” above; or	
 
 	Ÿ	 	we apply an amount equal to the net proceeds from the sale of the Principal Property to the purchase of another Principal Property or to the retirement of long-term Indebtedness within 365 days before or after the effective date of any such sale and lease-back transaction; provided that in lieu of applying such amount to such retirement, we may deliver debt securities to the Trustee for cancellation, such debt securities to be credited at the cost thereof to us.	
 
Notwithstanding the foregoing, we and our wholly-owned subsidiaries may enter into any sale lease-back transaction which would otherwise be subject to the foregoing restrictions if after giving effect thereto and at the time of determination, Aggregate Debt does not exceed the greater of (i) 15% of Consolidated Net Worth calculated as of the closing date of the sale-leaseback transaction or (ii) 15% of Consolidated Net Worth calculated as of the closing date of the offering of the notes.

Events of Default
 
Each of the following will be an event of default under the indenture for a series of debt securities:
 
 	Ÿ	 	our failure to pay principal or premium, if any, on that series when due at maturity, upon redemption or otherwise;	
 
 	Ÿ	 	our failure to pay any interest on that series for 30 days after the interest becomes due;	
 
 	Ÿ	 	our failure to perform, or our breach of, any other covenant, agreement or condition in the indenture in respect of that series for 60 days after either the Trustee or holders of at least 25% in principal amount of the outstanding debt securities of that series have given us written notice of the breach in the manner required by the indenture; and	
 
 	Ÿ	 	specified events involving our bankruptcy, insolvency or reorganization.	
 
An event of default under one series of debt securities does not necessarily constitute an event of default under any other series of debt securities. If an event of default for a series of debt securities occurs and is continuing (other than an event of default described in the fifth bullet point above), either the Trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series may declare the
 
10

Table of Contents
principal amount plus accrued and unpaid interest of all the debt securities of that series due and immediately payable. In order to declare the principal amount and accrued and unpaid interest of that series of debt securities due and immediately payable, the Trustee or the holders must deliver a notice that satisfies the requirements of the indenture. Upon a declaration by the Trustee or the holders, we will be obligated to pay the principal amount plus accrued and unpaid interest of the series of debt securities so declared due and payable.
 
If an event of default described in the fifth bullet point above occurs and is continuing, then the entire principal amount plus accrued and unpaid interest of the outstanding debt securities (or such lesser amount as may be provided in the terms of the securities) will automatically become due immediately and payable without any declaration or other act on the part of the Trustee or any holder.
 
However, after any declaration of acceleration of a series of debt securities or any automatic acceleration under the fifth bullet point above, but before a judgment or decree for payment has been obtained, the holders of a majority in principal amount of outstanding debt securities of any series may rescind this accelerated payment requirement if all existing events of default, except for nonpayment of the principal and interest on the debt securities of that series that has become due solely as a result of the accelerated payment requirement, have been cured or waived and if the rescission of acceleration would not conflict with any judgment or decree. The holders of a majority in principal amount of the outstanding debt securities of any series also have the right to waive past defaults, except a default in paying principal, premiums, if any, or interest on any outstanding debt security, or in respect of a covenant or provision that cannot be modified or amended without the consent of all holders of the debt securities of that series.
 
If an event of default occurs and is continuing, the Trustee will generally have no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders offer reasonable indemnity to the Trustee. The holders of a majority in principal amount of the outstanding debt securities of any series will generally have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on the Trustee for the debt securities of that series, provided that:
 
 	Ÿ	 	the direction is not in conflict with any law or the indenture;	
 
 	Ÿ	 	the Trustee may take any other action it deems proper which is not inconsistent with the direction; and	
 
 	Ÿ	 	the Trustee will generally have the right to decline to follow the direction if an officer of the Trustee determines, in good faith, that the proceeding would involve the Trustee in personal liability or would otherwise be contrary to applicable law or would be unduly prejudicial to the rights of any other holder of a debt security.	
 
A holder of a debt security of any series may only pursue a remedy under the indenture if:
 
 	Ÿ	 	the holder gives the Trustee written notice of a continuing event of default for that series;	
 
 	Ÿ	 	holders of at least 25% in principal amount of the outstanding debt securities of that series make a written request to the Trustee to institute proceedings with respect to the event of default;	
 
 	Ÿ	 	the holders offer reasonable indemnity to the Trustee;	
 
 	Ÿ	 	the Trustee fails to pursue that remedy within 60 days after receipt of the notice, request and offer of indemnity; and	
 
 	Ÿ	 	during that 60-day period, the holders of a majority in principal amount of the debt securities of that series do not give the Trustee a direction inconsistent with the request.	
 
However, these limitations do not apply to a suit by a holder of a debt security demanding payment of the principal, premium, if any, or interest on a debt security on or after the date the payment is due.
 
11

Table of Contents
We will be required to furnish to the Trustee annually a statement by some of our officers regarding our performance or observance of any of the terms of the indenture and specifying all of our known defaults, if any.
 
Modification and Waiver
 
When authorized by resolution of our board of directors, we may enter into one or more supplemental indentures with the Trustee without the consent of the holders of the debt securities in order to:

When authorized by resolution of our board of directors, we may enter into one or more supplemental indentures with the Trustee in order to add to, change or eliminate provisions of an indenture or to modify the rights of the holders of one or more series of debt securities if we obtain the consent of the holders of a majority in principal amount of the outstanding debt securities of all series affected by the supplemental indenture, treated as one class. However, without the consent of the holders of each outstanding debt security affected by the supplemental indenture, we may not enter into a supplemental indenture that:
 
 	Ÿ	 	reduces the rates of or changes the time for payment of interest on the debt securities;	
 
 	Ÿ	 	reduces the principal amount of, or changes the maturity of, any debt security;

Defeasance
 
When we use the term defeasance, we mean discharge from some or all of our obligations under the indenture. If we irrevocably deposit with the Trustee funds or government securities sufficient to make payments of all principal, premium, if any, and interest on the debt securities of a series on the dates those payments are due and payable and comply with all other conditions to defeasance set forth in the indenture, then, at our option, either of the following will occur:
 
 	Ÿ	 	we will be discharged from our obligations with respect to the debt securities of that series, which is referred to in this prospectus as “legal defeasance”; or	
 
 	Ÿ	 	we will no longer have any obligation to comply with the restrictive covenants under the indenture, and the related events of default will no longer apply to us, but some of our other obligations under the indenture and the debt securities of that series, including our obligation to make payments on those debt securities, will survive, collectively referred to in this prospectus as “covenant defeasance”;	
 
provided that no default with respect to the outstanding debt securities of that series has occurred and is continuing at the time of such deposit after giving effect to the deposit, or in the case of legal defeasance, no default relating to bankruptcy or insolvency has occurred and is continuing at any time on or before the 91 st day after the date of such deposit, it being understood that this condition is not deemed satisfied until after the 91 st day.
 
If we legally defease a series of debt securities, the holders of the debt securities of the series affected will not be entitled to the benefits of the indenture, except for our obligations to:
 
 	Ÿ	 	the rights of holders to receive principal, premium, if any, interest and the redemption price when due;	
 
 	Ÿ	 	register the transfer or exchange of debt securities; and	
 
 	Ÿ	 	replace mutilated, destroyed, lost or stolen debt securities.	
 
We may legally defease a series of debt securities notwithstanding any prior exercise of our option of covenant defeasance in respect of such series.
 
We will be required to deliver to the Trustee an opinion of counsel that the deposit and related defeasance would not cause the holders of the debt securities to recognize gain or loss for federal income tax purposes and that the holders would be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if the deposit and related defeasance had not occurred. If we elect legal defeasance, that opinion of counsel must be based upon a ruling from the United States Internal Revenue Service or a change in law to that effect.
 
Satisfaction and Discharge
 
We may discharge our obligations under the indenture while securities remain outstanding if (1) all outstanding debt securities issued under the indenture have become due and payable, (2) all outstanding debt
 
13

Table of Contents
securities issued under the indenture have or will become due and payable at their stated maturity within one year or (3) all outstanding debt securities issued under the indenture are scheduled for redemption in one year, and in each case, we have deposited with the Trustee an amount sufficient to pay and discharge all outstanding debt securities issued under the indenture on the date of their scheduled maturity or the scheduled date of the redemption, paid all other amounts payable under the indenture and delivered to the Trustee all certificates required by the indenture.
 
Book-Entry System
 
We have obtained the information in this section concerning The Depository Trust Company (“DTC”), Clearstream Banking, Luxembourg (“Clearstream, Luxembourg”) and Euroclear Bank S.A./N.V., as operator of the Euroclear System (“Euroclear”) and their book-entry systems and procedures from sources that we believe to be reliable. We take no responsibility for an accurate portrayal of this information. In addition, the description of the clearing systems in this section reflects our understanding of the rules and procedures of DTC, Clearstream, Luxembourg and Euroclear as they are currently in effect. Those systems could change their rules and procedures at any time.
 
Unless otherwise specified in a prospectus supplement, the debt securities will initially be represented by one or more fully registered global notes. Each such global note will be deposited with, or on behalf of, DTC or any successor thereto and registered in the name of Cede & Co. (DTC’s nominee). You may hold your interests in the global notes in the United States through DTC, or in Europe through Clearstream, Luxembourg or Euroclear, either as a participant in such systems or indirectly through organizations which are participants in such systems. Clearstream, Luxembourg and Euroclear will hold interests in the global notes on behalf of their respective participating organizations or customers through customers’ securities accounts in Clearstream, Luxembourg’s or Euroclear’s names on the books of their respective depositaries, which in turn will hold those positions in customers’ securities accounts in the depositaries’ names on the books of DTC. Citibank, N.A. will act as depositary for Clearstream, Luxembourg and JPMorgan Chase Bank will act as depositary for Euroclear.
 
So long as DTC or its nominee is the registered owner of the global securities representing the debt securities, DTC or such nominee will be considered the sole owner and holder of the debt securities for all purposes of the debt securities and the indenture. Except as provided below, owners of beneficial interests in the debt securities will not be entitled to have the debt securities registered in their names, will not receive or be entitled to receive physical delivery of the debt securities in definitive form and will not be considered the owners or holders of the debt securities under the indenture, including for purposes of receiving any reports delivered by us or the Trustee pursuant to the indenture. Accordingly, each person owning a beneficial interest in a debt security must rely on the procedures of DTC or its nominee and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, in order to exercise any rights of a holder of debt securities.
 
Unless and until we issue the debt securities in fully certificated, registered form under the limited circumstances described below under the heading “ —Certificated Debt Securities ”:
 
 	Ÿ	 	you will not be entitled to receive a certificate representing your interest in the debt securities;	
 
 	Ÿ	 	all references in this prospectus or an accompanying prospectus supplement to actions by holders will refer to actions taken by DTC upon instructions from its direct participants; and	
 
 	Ÿ	 	all references in this prospectus or an accompanying prospectus supplement to payments and notices to holders will refer to payments and notices to DTC or Cede & Co., as the registered holder of the debt securities, for distribution to you in accordance with DTC procedures.

Table of Contents
The Depository Trust Company
 
DTC will act as securities depositary for the debt securities. The debt securities will be issued as fully registered debt securities registered in the name of Cede & Co. DTC is:
 
 	Ÿ	 	a limited-purpose trust company organized under the New York Banking Law;	
 
 	Ÿ	 	a “banking organization” under the New York Banking Law;	
 
 	Ÿ	 	a member of the Federal Reserve System;	
 
 	Ÿ	 	a “clearing corporation” under the New York Uniform Commercial Code; and	
 
 	Ÿ	 	a “clearing agency” registered under the provisions of Section 17A of the Securities Exchange Act of 1934, as amended.	
 
DTC holds securities that its direct participants deposit with DTC. DTC facilitates the settlement among direct participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in direct participants’ accounts, thereby eliminating the need for physical movement of securities certificates.
 
Direct participants of DTC include securities brokers and dealers (including the underwriters), banks, trust companies, clearing corporations and certain other organizations. DTC is owned by a number of its direct participants. Indirect participants of DTC, such as securities brokers and dealers, banks and trust companies, can also access the DTC system if they maintain a custodial relationship with a direct participant.
 
Purchases of debt securities under DTC’s system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each beneficial owner is in turn to be recorded on the records of direct participants and indirect participants. Beneficial owners will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct participants or indirect participants through which such beneficial owners entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in debt securities, except as provided below in “—Ce rtificated Debt Securities .”
 
To facilitate subsequent transfers, all debt securities deposited with DTC are registered in the name of DTC’s nominee, Cede & Co. The deposit of debt securities with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities. DTC’s records reflect only the identity of the direct participants to whose accounts such debt securities are credited, which may or may not be the beneficial owners. The participants will remain responsible for keeping account of their holdings on behalf of their customers.
 
Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.
 
Book-Entry Format
 
Under the book-entry format, the Trustee will pay interest or principal payments to Cede & Co., as nominee of DTC. DTC will forward the payment to the direct participants, who will then forward the payment to the indirect participants (including Clearstream, Luxembourg or Euroclear) or to you as the beneficial owner. You may experience some delay in receiving your payments under this system. Neither we, the Trustee nor any

Table of Contents
paying agent has any direct responsibility or liability for the payment of principal or interest on the debt securities to owners of beneficial interests in the debt securities.
 
DTC is required to make book-entry transfers on behalf of its direct participants and is required to receive and transmit payments of principal, premium, if any, and interest on the debt securities. Any direct participant or indirect participant with which you have an account is similarly required to make book-entry transfers and to receive and transmit payments with respect to the debt securities on your behalf. We and the Trustee have no responsibility for any aspect of the actions of DTC, Clearstream, Luxembourg or Euroclear or any of their direct or indirect participants. In addition, we and the Trustee have no responsibility or liability for any aspect of the records kept by DTC, Clearstream, Luxembourg, Euroclear or any of their direct or indirect participants relating to or payments made on account of beneficial ownership interests in the debt securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. We also do not supervise these systems in any way.
 
The Trustee will not recognize you as a holder under the indenture, and you can only exercise the rights of a holder indirectly through DTC and its direct participants. DTC has advised us that it will only take action regarding a debt security if one or more of the direct participants to whom the debt security is credited directs DTC to take such action and only in respect of the portion of the aggregate principal amount of the debt securities as to which that participant or participants has or have given that direction. DTC can only act on behalf of its direct participants. Your ability to pledge debt securities to non-direct participants, and to take other actions, may be limited because you will not possess a physical certificate that represents your debt securities.
 
Neither DTC nor Cede & Co. (nor such other DTC nominee) will consent or vote with respect to the debt securities unless authorized by a direct participant in accordance with DTC’s procedures. Under its usual procedures, DTC will mail an omnibus proxy to us as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the debt securities are credited on the record date (identified in a listing attached to the omnibus proxy).
 
Clearstream, Luxembourg or Euroclear will credit payments to the cash accounts of Clearstream, Luxembourg customers or Euroclear participants in accordance with the relevant system’s rules and procedures, to the extent received by its depositary. These payments will be subject to tax reporting in accordance with relevant United States tax laws and regulations. Clearstream, Luxembourg or the Euroclear Operator, as the case may be, will take any other action permitted to be taken by a holder under the indenture on behalf of a Clearstream, Luxembourg customer or Euroclear participant only in accordance with its relevant rules and procedures and subject to its depositary’s ability to effect those actions on its behalf through DTC.
 
DTC, Clearstream, Luxembourg and Euroclear have agreed to the foregoing procedures in order to facilitate transfers of the debt securities among participants of DTC, Clearstream, Luxembourg and Euroclear. However, they are under no obligation to perform or continue to perform those procedures, and they may discontinue those procedures at any time.
 
Transfers Within and Among Book-Entry Systems
 
Transfers between DTC’s direct participants will occur in accordance with DTC rules. Transfers between Clearstream, Luxembourg customers and Euroclear participants will occur in accordance with its applicable rules and operating procedures.
 
DTC will effect cross-market transfers between persons holding directly or indirectly through DTC, on the one hand, and directly or indirectly through Clearstream, Luxembourg customers or Euroclear participants, on the other hand, in accordance with DTC rules on behalf of the relevant European international clearing system by its depositary. However, cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in that system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing

Table of Contents
system will, if the transaction meets its settlement requirements, instruct its depositary to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream, Luxembourg customers and Euroclear participants may not deliver instructions directly to the depositaries.
 
Because of time-zone differences, credits of securities received in Clearstream, Luxembourg or Euroclear resulting from a transaction with a DTC direct participant will be made during the subsequent securities settlement processing, dated the business day following the DTC settlement date. Those credits or any transactions in those securities settled during that processing will be reported to the relevant Clearstream, Luxembourg customer or Euroclear participant on that business day. Cash received in Clearstream, Luxembourg or Euroclear as a result of sales of securities by or through a Clearstream,
 
Luxembourg customer or a Euroclear participant to a DTC direct participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream, Luxembourg or Euroclear cash amount only as of the business day following settlement in DTC.
 
Although DTC, Clearstream, Luxembourg and Euroclear has agreed to the foregoing procedures in order to facilitate transfers of debt securities among their respective participants, they are under no obligation to perform or continue to perform such procedures and such procedures may be discontinued at any time.
 
Certificated Debt Securities
 
Unless and until they are exchanged, in whole or in part, for debt securities in definitive form in accordance with the terms of the debt securities, the debt securities may not be transferred except (1) as a whole by DTC to a nominee of DTC or (2) by a nominee of DTC to DTC or another nominee of DTC or (3) by DTC or any such nominee to a successor of DTC or a nominee of such successor.
 
We will issue debt securities to you or your nominees, in fully certificated registered form, rather than to DTC or its nominees, only if:
 
 	Ÿ	 	we advise the Trustee in writing that DTC is no longer willing or able to discharge its responsibilities properly or that DTC is no longer a registered clearing agency under the Securities Exchange Act of 1934, as amended, and the Trustee or we are unable to locate a qualified successor within 90 days;	
 
 	Ÿ	 	an event of default has occurred and is continuing under the indenture; or	
 
 	Ÿ	 	we, at our option, elect to terminate the book-entry system through DTC.	
 
If any of the three above events occurs, DTC is required to notify all direct participants that debt securities in fully certificated registered form are available through DTC. DTC will then surrender the global note representing the debt securities along with instructions for re-registration. The Trustee will re-issue the debt securities in fully certificated registered form and will recognize the registered holders of the certificated debt securities as holders under the indenture.
 
Unless and until we issue the debt securities in fully certificated, registered form, (1) you will not be entitled to receive a certificate representing your interest in the debt securities; (2) all references in this prospectus or an accompanying prospectus supplement to actions by holders will refer to actions taken by the depositary upon instructions from their direct participants; and (3) all references in this prospectus or an accompanying prospectus supplement to payments and notices to holders will refer to payments and notices to the depositary, as the registered holder of the debt securities, for distribution to you in accordance with its policies and procedures.
 
Notices
 
Holders will receive notices by mail at their addresses as they appear in the security register.

Table of Contents
Title
 
We may treat the person in whose name a debt security is registered on the applicable record date as the owner of the debt security for all purposes, whether or not it is overdue.
 
Governing Law
 
New York law will govern the indenture and the debt securities.
 
Regarding the Trustee
 
We and our affiliates maintain various commercial and service relationships with The Bank of New York Mellon Trust Company, N.A. and its affiliates in the ordinary course of business. Affiliates of The Bank of New York Mellon Trust Company, N.A. may in the future engage in lending, interest rate swap and other hedging transactions with us and our affiliates.
 
If an event of default occurs under the indenture and is continuing, the Trustee will be required to use the degree of care and skill of a prudent person in the conduct of that person’s own affairs. The Trustee will not become obligated to exercise any of its powers under the indenture at the request of any of the holders of any debt securities issued under the indenture unless those holders have offered the Trustee indemnity satisfactory to it.
 
If the Trustee becomes one of our creditors, its rights to obtain payment of claims in specified circumstances, or to realize for its own account on certain property received in respect of any such claim as security or otherwise will be limited under the terms of the indenture. The Trustee may engage in certain other transactions; however, if the Trustee acquires any conflicting interest (within the meaning specified under the Trust Indenture Act of 1939, as amended), it will be required to eliminate the conflict or resign.
 
 PLAN OF DISTRIBUTION
 
We may sell the offered securities (a) through agents; (b) through underwriters or dealers; (c) directly to one or more purchasers; or (d) through a combination of any of these methods of sale. We will identify the specific plan of distribution, including any underwriters, dealers, agents or direct purchasers and their compensation in a prospectus supplement.
 
 LEGAL MATTERS
 
Unless otherwise specified in the prospectus supplement accompanying this prospectus, Fenwick & West LLP, 801 California Street, Mountain View, California 94041, will provide opinions regarding the authorization and validity of the securities. Any underwriters will also be advised about the validity of the securities and other legal matters by their own counsel, which will be named in the prospectus supplement.
