Fiscal 2012 Compared with Fiscal 2011-Financial Performance

Net sales increased 7%, with net product sales increasing 5% and service revenue increasing 12%. Total gross margin decreased by 0.2 percentage points primarily as a result of higher sales discounts and unfavorable product pricing as well as unfavorable product mix shifts. These negative impacts to gross margin were partially offset by lower manufacturing costs, higher volume, lower restructuring charges, and lower amortization and impairment charges from purchased intangible assets. As a percentage of revenue, research and development, sales and marketing, and general and administrative expenses collectively declined by 2.7 percentage points due to the expense reductions we implemented in the fourth quarter of fiscal 2011 and in fiscal 2012. General and administrative expenses increased due primarily to impairment charges on real estate held for sale. Operating income as a percentage of revenue increased by 4.1 percentage points, primarily as a result of our sales increase, lower restructuring charges, lower amortization of purchased intangible assets and operating expense management. Diluted earnings per share increased by 27% from the prior year, a result of both a 24% increase in net income and a decline in our diluted share count of 159 million shares.

Fiscal 2012 Compared with Fiscal 2011-Business Summary

Our solid fiscal 2012 performance reflects continued execution on our plan to deliver profitable growth. In a challenging global macroeconomic environment we grew profits faster than revenue as revenue increased by 7% while net income increased by 24%. Our net income increase was in part due to lower restructuring charges in the current fiscal year.

In fiscal 2012, revenue increased by $2.8 billion. The Americas contributed $1.5 billion of the increase led by higher sales in the United States. APJC contributed $0.9 billion to the revenue increase led by strong sales growth in Japan. EMEA added $0.5 billion to the revenue increase in fiscal 2012. Both our product and service categories experienced revenue growth across each of our geographic segments. We encountered certain challenges from a geographic perspective, such as those we identified in fiscal 2012 related to macroeconomic challenges in much of Europe, which are expected to continue in fiscal 2013. Partially offsetting these challenges, we saw solid growth in fiscal 2012 in certain emerging countries such as Mexico and Brazil within the Americas, China within APJC, and Russia within EMEA. We believe our prospects in most emerging countries are strong and we plan to align more of our resources to meet expected further opportunities in these countries.

From a customer markets standpoint, in fiscal 2012 we had solid revenue growth across the service provider, commercial, and enterprise markets. The public sector customer market experienced flat revenue growth in fiscal 2012 as compared with fiscal 2011. Global public sector spending was a challenge for us in fiscal 2012, particularly in the Americas, with lower U.S. federal government spending, and in parts of EMEA due to continued austerity measures taking place in parts of the region. We expect these challenges in the public sector to continue into fiscal 2013.

In fiscal 2012, net product sales increased by $1.8 billion while service revenue increased by $1.0 billion. Data Center products provided $0.6 billion of the increase in net product sales, our core Switching and NGN Routing products collectively provided $0.6 billion, Service Provider Video provided $0.4 billion, and Wireless products contributed $0.3 billion of the increase. These are key product areas for us, which along with the Service revenue contribution reflect, in our view, the success we are experiencing with our technology architectures and our ability to deliver customer solutions, particularly in the enterprise and service provider data center and cloud environments.

With regard to profitability, our profits grew faster than revenue during fiscal 2012. This was attributable to lower operating expenses as a percentage of revenue driven by the cost reduction efforts we began in fiscal 2011, and substantially completed in fiscal 2012, and lower restructuring charges in fiscal 2012, coupled with relative stability in our gross margin. Our product gross margin benefited from value engineering and other cost savings, such as savings generated from price negotiations with our component suppliers.

In summary, we achieved solid and profitable growth in fiscal 2012, and did so while encountering a challenging global macroeconomic environment. We expect that we will continue to be impacted by some of the same

challenges in fiscal 2013. In particular, we expect to be impacted by continued weakness in the European economy, lower global public sector spending especially with regard to the U.S. federal government and European governments, and a continued conservative approach to IT-related capital spending as our customers respond to this difficult macroeconomic environment.

Fourth Quarter Snapshot

For the fourth quarter of fiscal 2012, as compared with the corresponding period in fiscal 2011, net sales increased by 4%, with net product sales increasing by 3% and service revenue increasing by 12%. With regard to our geographic segment performance, on a year-over-year basis, net sales increased by 7% in the Americas, decreased by 5% in EMEA, and increased by 9% in APJC. Total gross margin decreased by 0.7 percentage points, primarily as a result of higher sales discounts and unfavorable product pricing as well as unfavorable product mix shifts, partially offset by lower manufacturing costs and higher volume. As a percentage of revenue, research and development, sales and marketing, and general and administrative expenses collectively declined by 1.6 percentage points. For the fourth quarter of fiscal 2012, general and administrative expenses include $202 million of real estate charges, primarily related to impairment charges on real estate held for sale. Operating income as a percentage of revenue increased by 7.3 percentage points, primarily as a result of lower restructuring and other charges in the fourth quarter of fiscal 2012 and our sales increase. Diluted earnings per share increased by 64% from the prior year period, primarily as a result of a 56% increase in net income and also, to a lesser degree, from a decline of 142 million in our diluted share count.

Strategy and Focus Areas

We began in fiscal 2011, and had largely completed by the end of fiscal 2012, realigning our sales, services and engineering organizations in order to simplify our operating model, drive faster innovation, and focus on our five foundational priorities:

• Leadership in our core business (routing, switching, and associated services) which includes comprehensive security and mobility solutions

• Collaboration

• Data center virtualization and cloud

• Video

• Architectures for business transformation

We believe that focusing on these priorities best positions us to continue to expand our share of our customers' information technology spending. For a full discussion of our strategy and focus areas, see Item 1. Business.

Other Key Financial Measures

The following is a summary of our other key financial measures for fiscal 2012
compared with fiscal 2011 (in millions, except days sales outstanding in
accounts receivable ("DSO") and annualized inventory turns):



                                                            Fiscal        Fiscal

   Annualized inventory turns                                   11.7          11.8

Our product backlog at the end of fiscal 2012 was $5.0 billion, or 11% of fiscal 2012 net sales, compared with $4.5 billion at the end of fiscal 2011, or 10% of fiscal 2011 net sales.

CRITICAL ACCOUNTING ESTIMATES

The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States requires us to make judgments, assumptions, and estimates that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. Note 2 to the Consolidated Financial Statements describes the significant accounting policies and methods used in the preparation of the Consolidated Financial Statements. The accounting policies described below are significantly affected by critical accounting estimates. Such accounting policies require significant judgments, assumptions, and estimates used in the preparation of the Consolidated Financial Statements, and actual results could differ materially from the amounts reported based on these policies.

Revenue Recognition

Revenue is recognized when all of the following criteria have been met:

• Persuasive evidence of an arrangement exists. Contracts, Internet commerce agreements, and customer purchase orders are generally used to determine the existence of an arrangement.

• Delivery has occurred. Shipping documents and customer acceptance, when applicable, are used to verify delivery.

• The fee is fixed or determinable. We assess whether the fee is fixed or determinable based on the payment terms associated with the transaction and whether the sales price is subject to refund or adjustment.

• Collectibility is reasonably assured. We assess collectibility based primarily on the creditworthiness of the customer as determined by credit checks and analysis, as well as the customer's payment history.

In instances where final acceptance of the product, system, or solution is specified by the customer, revenue is deferred until all acceptance criteria have been met. When a sale involves multiple deliverables, such as sales of products that include services, the multiple deliverables are evaluated to determine the unit of accounting, and the entire fee from the arrangement is allocated to each unit of accounting based on the relative selling price. Revenue is recognized when the revenue recognition criteria for each unit of accounting are met.

The amount of product and service revenue recognized in a given period is affected by our judgment as to whether an arrangement includes multiple deliverables and, if so, our valuation of the units of accounting for multiple deliverables. According to the accounting guidance prescribed in Accounting Standards Codification ("ASC") 605, Revenue Recognition, we use vendor-specific objective evidence of selling price ("VSOE") for each of those units, when available. We determine VSOE based on our normal pricing and discounting practices for the specific product or service when sold separately. In determining VSOE, we require that a substantial majority of the historical standalone transactions have the selling prices for a product or service fall within a reasonably narrow pricing range, generally evidenced by approximately 80% of such historical standalone transactions falling within plus or minus 15% of the median rates. When VSOE does not exist, we apply the selling price hierarchy to applicable multiple-deliverable arrangements. Under the selling price hierarchy, third-party evidence of selling price ("TPE") will be considered if VSOE does not exist, and estimated selling price ("ESP") will be used if neither VSOE nor TPE is available. Generally, we are not able to determine TPE because our go-to-market strategy differs from that of others in our markets, and the extent of our proprietary technology varies among comparable products or services from those of our peers. In determining ESP, we apply significant judgment as we weigh a variety of factors, based on the facts and circumstances of the arrangement. We typically arrive at an ESP for a product or service that is not sold separately by considering company-specific factors such as geographies, competitive landscape, internal costs, profitability objectives, pricing practices used to establish bundled pricing, and existing portfolio pricing and discounting.

Some of our sales arrangements have multiple deliverables containing software and related software support components. Such sales arrangements are subject to the accounting guidance in ASC 985-605, Software-Revenue Recognition.

As our business and offerings evolve over time, our pricing practices may be required to be modified accordingly, which could result in changes in selling prices, including both VSOE and ESP, in subsequent periods. There were no material impacts during fiscal 2012, nor do we currently expect a material impact in fiscal 2013 on our revenue recognition due to any changes in our VSOE, TPE, or ESP.

Revenue deferrals relate to the timing of revenue recognition for specific transactions based on financing arrangements, service, support, and other factors. Financing arrangements may include sales-type, direct-financing, and operating leases, loans, and guarantees of third-party financing. Our deferred revenue for products was $3.7 billion as of each July 28, 2012 and July 30, 2011. Technical support services revenue is deferred and recognized ratably over the period during which the services are to be performed, which typically is from one to three years. Advanced services revenue is recognized upon delivery or completion of performance. Our deferred revenue for services was $9.2 billion and $8.5 billion as of July 28, 2012 and July 30, 2011, respectively.

We make sales to distributors and retail partners which we refer to as two-tier systems 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. Our distributors and retail partners participate in various cooperative marketing and other programs, and we maintain estimated accruals and allowances for these programs. If actual credits received by our distributors and retail partners under these programs were to deviate significantly from our estimates, which are based on historical experience, our revenue could be adversely affected.

Allowances for Receivables and Sales Returns

The allowances for receivables were as follows (in millions, except
percentages):



                                                July 28, 2012        July 30, 2011
 Allowance for doubtful accounts               $           207      $           204
 Percentage of gross accounts receivable                   4.5 %                4.2 %
 Allowance for credit loss-lease receivables   $           247      $           237
 Percentage of gross lease receivables                     7.2 %                7.6 %
 Allowance for credit loss-loan receivables    $           122      $           103
 Percentage of gross loan receivables                      6.8 %                7.0 %

The allowance for doubtful accounts is based on our assessment of the collectibility of customer accounts. We regularly review the adequacy of these allowances by considering internal factors such as historical experience, credit quality and age of the receivable balances as well as external factors such as economic conditions that may affect a customer's ability to pay and expected default frequency rates, which are published by major third-party credit-rating agencies and are generally updated on a quarterly basis. We also consider the concentration of receivables outstanding with a particular customer in assessing the adequacy of our allowances for doubtful accounts. If a major customer's creditworthiness deteriorates, if actual defaults are higher than our historical experience, or if other circumstances arise, our estimates of the recoverability of amounts due to us could be overstated, and additional allowances could be required, which could have an adverse impact on our revenue.

The allowance for credit loss on financing receivables is also based on the assessment of collectibility of customer accounts. We regularly review the adequacy of the credit allowances determined either on an individual or a collective basis. When evaluating the financing receivables on an individual basis, we consider historical experience, credit quality and age of receivable balances, and economic conditions that may affect a customer's ability to pay. As discussed in Note 7 to the Consolidated Financial Statements, effective at the beginning of the second quarter of fiscal 2012 we refined our methodology for determining the portion of our allowance for credit loss that is evaluated on a collective basis. The refinement consists of more systematically giving effect to economic conditions, concentration of risk and correlation. We also began to use expected default frequency rates published by a major third-party credit-rating agency as well as our own historical loss rate in the event of default. Determination of expected default frequency rates and loss factors associated with internal credit risk

ratings as well as assessing economic conditions, concentration of risk, and correlation are complex and subjective. Our ongoing consideration of all these factors could result in an increase in our allowance for credit loss in the future, which could adversely affect our revenue.

Both accounts receivable and financing receivables are charged off at the point when they are considered uncollectible.

A reserve for future sales returns is established based on historical trends in product return rates. The reserve for future sales returns as of July 28, 2012 and July 30, 2011 was $129 million and $106 million, respectively, and was recorded as a reduction of our accounts receivable. If the actual future returns were to deviate from the historical data on which the reserve had been established, our revenue could be adversely affected.

Inventory Valuation and Liability for Purchase Commitments with Contract Manufacturers and Suppliers

Our inventory balance was $1.7 billion and $1.5 billion as of July 28, 2012 and July 30, 2011, respectively. Inventory is written down based on excess and obsolete inventories determined primarily by future demand forecasts. Inventory write-downs are measured as the difference between the cost of the inventory and market, based upon assumptions about future demand, and are charged to the provision for inventory, which is a component of our cost of sales. At the point of the loss recognition, a new, lower cost basis for that inventory is established, and subsequent changes in facts and circumstances do not result in the restoration or increase in that newly established cost basis.

We record a liability for firm, noncancelable, and unconditional purchase commitments with contract manufacturers and suppliers for quantities in excess of our future demand forecasts consistent with the valuation of our excess and obsolete inventory. As of July 28, 2012, the liability for these purchase commitments was $193 million, compared with $168 million as of July 30, 2011, and was included in other current liabilities.

Our provision for inventory was $115 million, $196 million, and $94 million for fiscal 2012, 2011, and 2010, respectively. The provision for the liability related to purchase commitments with contract manufacturers and suppliers was $151 million, $114 million, and $8 million in fiscal 2012, 2011, and 2010, respectively. On a combined basis, the $44 million decline in our provisions for inventory and purchase commitments with contract manufacturers and suppliers for fiscal 2012 was primarily due to the absence in the current fiscal year of charges we recorded in connection with the restructuring and realignment of our consumer business during fiscal 2011. If there were to be a sudden and significant decrease in demand for our products, or if there were a higher incidence of inventory obsolescence because of rapidly changing technology and customer requirements, we could be required to increase our inventory write-downs, and our liability for purchase commitments with contract manufacturers and suppliers, and accordingly our profitability could be adversely affected. We regularly evaluate our exposure for inventory write-downs and the adequacy of our liability for purchase commitments. Inventory and supply chain management remain areas of focus as we balance the need to maintain supply chain flexibility to help ensure competitive lead times with the risk of inventory obsolescence, particularly in light of current macroeconomic uncertainties and conditions and the resulting potential for changes in future demand forecast.

Warranty Costs

The liability for product warranties, included in other current liabilities, was $415 million as of July 28, 2012, compared with $342 million as of July 30, 2011. See Note 12 to the Consolidated Financial Statements. Our products are generally covered by a warranty for periods ranging from 90 days to five years, and for some products we provide a limited lifetime warranty. We accrue for warranty costs as part of our cost of sales based on associated material costs, technical support labor costs, and associated overhead. Material cost is estimated based primarily upon historical trends in the volume of product returns within the warranty period and the cost to repair or replace the equipment. Technical support labor cost is estimated based primarily upon historical trends in the rate of customer cases and the cost to support the customer cases within the warranty period. Overhead cost is applied based on estimated time to support warranty activities.

The provision for product warranties issued during fiscal 2012, 2011, and 2010 was $661 million, $456 million, and $469 million, respectively. The increase in . . .
