PART I
 
Item 1.   Business
 
General
 
We are a global provider of solutions for the collection, storage, management, protection and use of digital content, including audio and video. Our principal products are hard drives, which are devices that use one or more rotating magnetic disks (“magnetic media”) to store and allow fast access to data. Hard drives are currently the primary storage medium for digital content. Our hard drives are used in desktop and notebook computers, corporate and cloud computing data centers, home entertainment equipment and stand-alone consumer storage devices. In addition to hard drives, our other products include solid-state drives and home entertainment and networking products.
 
Business Strategy
 
Our business strategy is to provide a broad selection of reliable, high quality storage devices at a low total cost of ownership and with high efficiency and speed. We have designed our business strategy to accommodate significant unit and revenue growth with relatively small increases in operating expenses and to consistently achieve high asset utilization. We believe this strategy helps accomplish the following:
 
  •  distinguishes us in the dynamic and competitive electronic data storage industry;
 
  •  provides value to our customers;
 
  •  allows us to better achieve consistent financial performance, including strong returns on invested capital; and
 
  •  provides continued diversification of our storage product portfolio and entry into additional markets.
 
Industry
 
We believe that growth in the unit sales within the electronic data storage industry has continued to outpace the growth in the unit sales of all personal computers (“PCs”). For example, there were approximately 89% more hard drives sold than PCs in calendar 2010, based on industry data. We believe the following factors continue to drive the unit growth of storage device sales in addition to PCs:
 
  •  consumer use of data storage devices for the playing, retention and creation of digital content for personal use;
 
  •  growth of the external storage devices, permitting the easy storage, portability and backup of digital data such as music, photographs or video; and
 
  •  growth of Internet-based applications, such as social networking, and cloud computing which drives the need for digital content storage and distribution.
 
For a discussion of risks relating to the electronic data storage industry, please see Item 1A of this Annual Report on Form 10-K.
 
Client Compute
 
Client compute storage devices consist of internal hard drives and solid-state drives for desktop and mobile PCs. Hard drives and solid-state drives store the computer operating system and application software, as well as the data used by the applications. Desktop PCs are intended for regular use at a single location in homes, businesses and multi-user networks. Mobile PCs, primarily notebook computers, are used both in and away from homes and businesses. We believe that the demand for client compute hard drives and solid-state drives will grow primarily due to the increasing demand in emerging countries, continued corporate refreshes, the proliferation of digital content and requirements for increasing performance, small size and low power consumption.
 
Client Non-Compute
 
External Storage.  External storage devices supplement the storage space of PC systems for home and small office networks, back up data on internal drives and are used for portability and security. We believe there is a growing

Table of Contents

consumer need to back up personal digital content and externally expand storage capacity. Media players connect to a user’s television or home theater system and play digital movies, music and photos from an integrated hard drive, USB mass storage devices or content services accessed over the Internet. We also believe there is a growing need for consumers to play and view their personal stored digital content and premium content from the Internet on their television and home theater system consistent with the growing trend to digitize rich content and data.
 
Consumer Electronics.  Hard drives for CE products are primarily used in digital video recorders (“DVRs”) and game consoles. DVRs offer greater consumer viewing flexibility and enhanced capabilities such as pausing live television, simplifying the process of recording and cataloging recorded television programs and quickly forwarding or returning to any section of a recorded television program. Game consoles enable users to save games, movies, music, pictures and other user generated content. We believe growth in consumer electronics will continue to create demand for higher capacity hard drives. Solid-state drives are also used in consumer electronics products which are primarily designed for small form factor, battery powered consumer hand held devices, such as tablets and smartphones.
 
Enterprise
 
Enterprise storage devices consist of hard drives and solid-state drives for mission critical storage applications, also referred to as traditional enterprise, and nearline storage applications. Mission critical storage applications are essential to the operations of an enterprise and require high performance, high reliability hard drives and solid-state drives. Nearline storage applications are business critical but require higher capacity and lower power consumption hard drives. Nearline hard drives are more cost effective than traditional enterprise hard drives while offering higher capacities and maintaining similar reliability, scalability and performance. Nearline hard drives have stimulated applications such as video surveillance, video editing/broadcasting and medical imaging, and are also becoming commonplace for IT infrastructure applications such as databases, scientific computing, web content, web caching, web search engines and electronic mail. We believe that shipments of nearline hard drive units comprised approximately 41% of enterprise hard drives in calendar 2010 compared to 36% in calendar 2009. We believe that nearline hard drives will continue to consume a growing portion of the highest capacity hard drives in the next three years. Enterprise also consists of solid-state drives for use in embedded applications, such as network communications, industrial, medical, military and aerospace, which require high durability and long life cycles.
 
There is a trend towards centralization of information storage and delivery of Internet-based services through cloud computing. Cloud computing delivers shared resources, software and information to users on demand on a multitude of devices, such as client PCs and handheld computing devices. Most cloud computing models consist of services delivered through large data centers that utilize enterprise-class servers. The infrastructure to support cloud computing storage needs is driving the demand for enterprise-class hard drives and solid-state drives.
 
Other Market Opportunities
 
We regularly review opportunities to apply our knowledge of data storage technology to markets that we do not currently serve. Based on our significant investments, we believe we have the technology building blocks to increase our overall market penetration and be a full-line data storage solutions supplier. Consistent with our measured and deliberate approach to new market entries in the recent past, our approach to additional new markets will be based on a careful assessment of the risks, rewards, requirements and profit potential of such actions.
 
Products
 
We offer a broad line of storage devices. Our hard drives currently include 3.5-inch and 2.5-inch form factors, capacities ranging from 80 gigabytes (“GB”) to 3 terabytes (“TB”), nominal rotation speeds up to 10,000 revolutions per minute (“RPM”), and interfaces such as Serial Advanced Technology Attachment (“SATA”) and Serial Attached SCSI (Small Computer System Interface) (“SAS”). In addition, we offer a family of hard drives specifically designed to consume substantially less power than standard drives, utilizing our WD GreenPower Technologytm. Our solid-state drives currently include 2.5-inch and Compact Flash form factors, capacities ranging from 1 GB to 256 GB, and interfaces such as SATA and PATA.

Research and development expenses totaled $703 million, $611 million and $509 million in 2011, 2010 and 2009, respectively. For a discussion of risks related to our development of new products, see Item 1A of this Annual Report on Form 10-K.
 
Technology and Product Development
 
Hard drives provide non-volatile data storage, which means that the data remains present when power is no longer applied to the device. The primary measures of hard drive performance include:
 
  •  Acoustics — sound power emitted during hard drive operation, commonly expressed in decibels, and perceived loudness due to sound pressure, commonly expressed in sones;
 
  •  Data transfer rate — sustained rate of data transfer to and from the disk, commonly expressed in gigabits per second. One gigabit equals one billion bits;
 
  •  Power Consumption — which is the amount of electricity required to operate the drive, measured in watts;
 
  •  Seek time — time needed to position the heads over a selected track on the disk surface, commonly expressed in milliseconds;
 
  •  Spindle rotation speed — nominal rotation speed of the disks inside the hard drive, commonly expressed in RPM or latency. Spindle rotation speeds commonly stated as 5,400, 7,200 and 10,000 RPM are sometimes approximations; and
 
  •  Storage capacity — which is the amount of data that can be stored on the hard drive, commonly expressed in GB or TB. As defined in the hard drive industry, one GB equals one billion bytes and one TB equals one trillion bytes. A byte is a digital character, typically comprised of eight bits. A bit is a binary digit, the smallest unit of information in a digital system.
 
Industry-standard interfaces allow the drives to communicate with the host system. The primary interface for PCs is SATA and the primary interfaces for enterprise systems are SAS, Fibre Channel Arbitrated Loop (“FC-AL”) and SATA.
 
The main components of the hard drive are a Head-Disk-Assembly (“HDA”) and a Printed Circuit Board Assembly (“PCBA”).
 
The HDA includes heads, magnetic media, head positioning mechanism (“actuator”) and spindle motor. A rigid base and top cover contain these components in a contamination-controlled environment. One or more disks positioned around a motor-driven spindle hub that rotates the disks comprise the disk-pack assembly. The disk is made up of a smooth substrate on which thin layers of magnetic materials are deposited. The head stack assembly (“HSA”) is comprised of a magnetic positioner and a pivot-arm module on which the individual heads, including suspension, are mounted. Each disk has a head suspended directly above it, which can read data from or write data to the spinning disk.
 
The PCBA includes both standard and custom integrated circuits, an interface connector to the host computer and a power connector. The integrated circuits on the printed circuit board typically include a power device that controls the motor and HSA positioner, and a System on Chip (SoC) comprised of a drive interface, controller and recording channel.

Table of Contents

The drive interface receives instructions from the host computer, while the controller directs the flow of data to or from the disks and controls the heads. The location of data on each disk is logically maintained in concentric tracks divided into sectors. The host computer sends instructions to the controller to read data from or write data to the disks, based on logical track and sector locations. Guided by instructions from the controller, the HSA pivots in an arc across the disk until it reaches the selected track of a disk, where the data is recorded or retrieved.
 
The storage capacity of a hard drive is determined by the number of disks and each disk’s areal density (track density multiplied by bit density), which is a measure of the amount of data that can be stored on the recording surface of the disk per unit area. Head and magnetic media technologies are two of the key components affecting areal density. As areal density increases, achieving a given drive capacity potentially reduces product costs over time through reduced component requirements. We are vertically integrated in these two most important technology components of hard drives (heads and magnetic media). We also invest considerable resources in research and development, manufacturing infrastructure and capital equipment of head and magnetic media components, in order to secure our competitive position and cost structure.
 
Solid-state drives use semiconductor, non-volatile media, rather than magnetic media and magnetic heads, to store and allow fast access to data without any moving parts. The capacity of a solid-state drive is based on the total number of megabytes (“MB”) or GB of semiconductor media in the solid-state drive.
 
Our products generally leverage a common platform for various products within product families, and in some cases across product families, resulting in the commonality of components which reduces our exposure to changes in demand, facilitates inventory management and allows us to achieve lower costs through purchasing economies. This platform strategy also enables our customers to leverage their qualification efforts onto successive product models. For a discussion of risks related to technological innovations, see Item 1A of this Annual Report on Form 10-K.
 
Sales and Distribution
 
We maintain sales offices in selected parts of the world including the major geographies of the Americas, Asia Pacific, Europe and the Middle East. Our international sales, which include sales to foreign subsidiaries of United States (“U.S.”) companies but do not include sales to U.S. subsidiaries of foreign companies, represented 83%, 81% and 80% of our net revenue for 2011, 2010 and 2009, respectively. Sales to international customers may be subject to certain risks not normally encountered in domestic operations, including exposure to tariffs and various trade regulations. For a discussion regarding the risks related to sales to international customers, see Item 1A of this Annual Report on Form 10-K.
 
We perform our marketing and advertising functions internally and through outside firms utilizing both consumer media and trade publications targeting various reseller and end-user categories. We also maintain customer relationships through direct communication and providing information and support through our Web site. In accordance with standard hard drive industry practice, we provide distributors and retailers with limited price protection and programs under which we reimburse certain marketing expenditures. We also provide distributors, resellers and OEMs with other sales incentive programs.
 
Original Equipment Manufacturers.  OEMs purchase our products, either directly or through a contract manufacturer such as an original design manufacturer (“ODM”), and assemble them into the devices they build. OEMs typically seek to qualify two or more providers for each generation of products and generally will purchase products from those vendors for the life of that product. Many of our OEM customers utilize just-in-time inventory management processes or supply chain business models that allow for “build-to-order,” in which they do not build until there is a firm order. For certain OEMs, we maintain a base stock of finished goods inventory in facilities located near or adjacent to the OEM’s operations. We believe that our success depends on our ability to maintain and improve our strong relationships with the leading OEMs.
 
Distributors.  We use a broad group of distributors to sell our products to non-direct customers such as small computer and CE manufacturers, dealers, systems integrators, online retailers and other resellers. Distributors generally enter into non-exclusive agreements with us for the purchase and redistribution of our products in specific territories.
 
Retailers.  We sell our branded products directly to a select group of major retailers such as computer superstores, warehouse clubs, online retailers, and computer electronics stores, and authorize sales through distributors to smaller retailers. The retail channel complements our other sales channels while helping to build brand awareness for WD and our products. We also sell our branded products through our Web site.

For 2011 and 2010, no single customer accounted for 10% or more of our net revenue. For 2009, sales to Dell Inc. accounted for 10% of our net revenue. For a discussion of risks related to our customers, refer to Item 1A of this Annual Report on Form 10-K. For additional information regarding revenue recognition, sales by geographic region and major customer information, see Part II, Item 8, Notes 1 and 6 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.
 
Competition
 
We compete with manufacturers of hard drives for client compute, client non-compute and enterprise applications as well as manufacturers of solid-state drives. Our competitors include companies such as Hitachi Global Storage Technologies, Intel Corporation, Micron Technology, Inc., Samsung Electronics Co. Ltd., Seagate Technology, STEC, Inc. and Toshiba Corporation.
 
The storage industry is intensely competitive with hard drive and solid-state suppliers competing for sales to a limited number of major customers. Hard drives are highly substitutable due to the industry mandate of technical form, fit and function standards and we believe there are no substantial barriers for existing competitors to offer competing products. Hard drive manufacturers compete on the basis of product quality and reliability, storage capacity, unit price, product performance, production volume capabilities, delivery capability, leadership in time-to-market, time-to-volume and time-to-quality, service and support and ease of doing business. The relative importance of these factors varies by customer and market and we believe that we are generally competitive in all of these factors. Semiconductor media competes with hard drives along a range of product attributes. In particular, semiconductor media currently offers attractive functionality in consumer handheld applications requiring smaller form factors, lower power and less storage capacity, such as smartphones and tablets. Semiconductor media offers greater performance than hard drives in some storage applications. Advances in magnetic, optical or other data storage technologies could also result in competitive products for storing digital content with better performance or lower cost per unit of capacity than our products. We monitor the advantages, disadvantages and advances of the full array of storage technologies on an ongoing basis.
 
We differentiate WD by focusing on operational excellence, high product quality and reliability, and designing and incorporating into our storage devices desirable product performance attributes. We also differentiate WD by emphasizing non-product related attributes such as availability and rapid response to our customers, which requires accelerated design cycles, customer delivery, production flexibility and timely service and support. We believe that trust in a manufacturer’s reputation, its execution track record and the establishment of strategic relationships have become important factors in the selection of a storage device, particularly in a rapidly changing technology environment.
 
Seasonality
 
We have historically experienced seasonal fluctuations in our business with higher levels of demand in the first and second quarters of our fiscal year. This seasonality is a result of consumer spending at the beginning of the school year and during the holiday season. Seasonality can also be impacted by the growth in emerging markets and macroeconomic conditions. For a discussion of risks related to seasonality in our business, see Item 1A of this Annual Report on Form 10-K.
 
Service and Warranty
 
We generally warrant our newly manufactured products against defects in materials and workmanship from one to five years from the date of manufacture depending on the type of product. Our warranty obligation is generally limited to repair or replacement. We have engaged third parties in various countries in multiple regions to provide various levels of testing, processing and/or recertification of returned products for our customers.

We believe that we have significant know-how, unique product manufacturing processes, test and tooling, execution skills and human resources to continue to be successful and be able to grow, as necessary, our manufacturing operations. We strive to maintain manufacturing flexibility, high manufacturing yields, reliable products, and high-quality components. The critical elements of our hard drive production are high volume and utilization, low cost

assembly and testing, and maintaining close relationships with our strategic component suppliers to access best-of-class technology and manufacturing quality.
 
Hard drive manufacturing is a complex process involving the assembly of precision components with narrow tolerances and thorough testing. The assembly process occurs in a “clean room” environment that demands skill in process engineering and efficient space utilization to control the operating costs of this manufacturing environment. Our clean room manufacturing process consists of modular production units, each of which contains a number of work cells.
 
We continually evaluate our manufacturing processes in an effort to increase productivity, sustain and improve quality and decrease manufacturing costs. We continually evaluate which steps in the manufacturing process would benefit from automation and how automated manufacturing processes can improve productivity and reduce manufacturing costs. We leverage the efficiencies of contract manufacturers when strategically advantageous. For a discussion of risks related to manufacturing, see Item 1A of this Annual Report on Form 10-K.
 
Materials and Supplies
 
We use a number of components, equipment, goods and services in the manufacturing of our products. The key components of our hard drives are:
 
  •  magnetic heads;
 
  •  magnetic media;
 
  •  suspensions with related head gimbal assemblies (“HGAs”) and head stack assemblies (“HSAs”);
 
  •  spindle motors;
 
  •  custom and standard electronics such as system-on-chip, magnetic media, motor controllers, pre-amps and printed circuit boards;
 
  •  base and top covers; and
 
  •  magnets and related voice coil motors.
 
We design and manufacture a substantial portion of the heads and magnetic media required for our hard drives. We acquire all of the remaining components for our products from third party suppliers. The major components used in the manufacture of our solid-state drives (the semiconductor media and system-on-chip) and in our media players (the controller) are also acquired from third party suppliers. We believe that our sourcing strategy currently enables us to have the business flexibility needed to select the highest quality, low cost of ownership suppliers as product designs and technologies evolve.
 
We generally retain multiple suppliers for each of our component requirements but in some instances use sole sources for business reasons. Currently, we believe that there are no major issues with component availability. For a discussion of risks related to our component supplies, see Item 1A of this Annual Report on Form 10-K.
 
Backlog
 
A substantial portion of our orders are generally for shipments within 30 to 60 days of the placement of the order. Customers’ purchase orders typically may be canceled with relatively short notice to us, with little or no cost to the customer, or modified by customers to provide for delivery at a later date. In addition, for many of our OEMs utilizing just-in-time inventory, we do not generally require firm order commitments and instead, receive a periodic forecast of requirements. Therefore, backlog information as of the end of a particular period is not necessarily indicative of future levels of our revenue and profit and may not be comparable to prior periods.
 
Patents, Licenses and Proprietary Information
 
We own numerous patents and have many patent applications in process. We believe that, although our patents and patent applications have considerable value, the successful manufacturing and marketing of our products depends primarily upon the technical and managerial competence of our staff. Accordingly, the patents held and applied for do not ensure our future success.

Table of Contents

In addition to patent protection of certain intellectual property rights, we consider elements of our product designs and processes to be proprietary and confidential. We believe that our non-patented intellectual property, particularly some of our process technology, is an important factor in our success. We rely upon non-disclosure agreements and contractual provisions and a system of internal safeguards to protect our proprietary information. Despite these safeguards, there is a risk that competitors may obtain and use such information. The laws of foreign jurisdictions in which we conduct business may provide less protection for confidential information than the U.S.
 
We rely on certain technology that we license from other parties to manufacture and sell WD products. We believe that we have adequate cross-licenses and other agreements in place in addition to our own intellectual property portfolio to compete successfully in the hard drive industry. For discussion of risks related to our ownership and use of intellectual property, see Item 1A of this Annual Report on Form 10-K.
 
Environmental Regulation
 
We are subject to a variety of regulations in connection with our operations. We believe that we have obtained or are in the process of obtaining all necessary environmental permits for our operations. For a discussion of risks related to environmental regulation, see Item 1A of this Annual Report on Form 10-K.
 
Employees
 
As of July 1, 2011, we employed a total of 65,431 employees worldwide, excluding temporary employees and contractors. Many of our employees are highly skilled, and our continued success depends in part upon our ability to attract and retain such employees. Accordingly, we offer employee benefit programs which we believe are, in the aggregate, competitive with those offered by our competitors. We consider our employee relations to be good. For a discussion of risks related to our skilled employees, see Item 1A of this Annual Report on Form 10-K.

Item 1A.   Risk Factors
 
The successful completion of our planned acquisition of HGST is subject to risks and uncertainties, including obtaining the requisite regulatory approvals, and our business may suffer in the event we fail to successfully complete the acquisition.
 
In March 2011, we announced our planned acquisition of HGST. Completion of the planned acquisition of HGST is subject to risks and uncertainties, including, but not limited to:
 
  •  Required Government Approvals.  Completion of our planned acquisition of HGST is conditioned upon, among other things, obtaining required governmental approvals. While certain governmental approvals have been obtained, the transaction remains conditioned upon the receipt of approval from the United States, the European Union, the People’s Republic of China, Japan, Korea and Mexico. There is no assurance that we will obtain such approvals or, if obtained, the timing of the approvals. We agreed to take any and all actions to obtain the requisite governmental approvals in specified jurisdictions unless such action would reasonably be expected to materially impair the business operations of the combined company absent such imposed condition. There can be no assurance that conditions or changes will not be imposed and any such conditions or changes could have the effect of jeopardizing or delaying completion of the planned acquisition or reducing the anticipated benefits of the planned acquisition. If we agree to any material conditions in order to obtain any approvals required to complete the planned acquisition, the business and results of operations of the combined company may be adversely affected.
 
  •  Termination Fee.  If the acquisition agreement is terminated by any party because the acquisition has not closed by March 7, 2012, and if, as of the time of such termination, certain regulatory and antitrust closing conditions have not been satisfied due to the failure to receive any required antitrust or competition consent, approval or


12


Table of Contents

  clearance or any action by any certain governmental entities to prevent the acquisition for antitrust or competition reasons, then we will be required to pay a termination fee of $250 million.
 
  •  Transaction Costs.  We have incurred and will continue to incur costs relating to the planned acquisition (including significant legal and financial advisory fees) and many of these costs are payable by us whether or not the planned acquisition is completed.
 
  •  Time and Resources Commitment.  Matters relating to the planned acquisition (including integration planning) have and will continue to require substantial commitments of time and resources by our management team, which could otherwise have been devoted to other opportunities that may have been beneficial to us.
 
  •  Financing.  We may fail to complete the planned financing for the transaction.
 
These risks and uncertainties regarding the acquisition may adversely affect our relationships with our vendors and customers, which could harm our operating results. In addition, in the event that the acquisition is not completed or is delayed, our business could suffer and the current market price of our common stock may decline.
 
Even if we successfully complete our planned acquisition of HGST, we may fail to successfully integrate HGST’s business into our operations and realize the anticipated benefits from such integration on a timely basis, or at all, which could negatively impact our business.
 
The success of our planned acquisition of HGST will depend on our ability to realize the anticipated benefits from integrating HGST’s business into our operations. Due to legal restrictions, we and HGST have conducted, and until the completion of the planned acquisition will conduct, only limited planning regarding the integration of the two companies following the acquisition. Our ongoing business could be disrupted and our management’s attention diverted due to these integration planning activities and as a result of the actual integration of the two companies following the acquisition. Following the planned acquisition, we may fail to realize the anticipated benefits from this integration on a timely basis, or at all, for a variety of reasons, including the following:
 
  •  difficulties entering new markets or manufacturing in new geographies where we have no or limited direct prior experience;
 
  •  difficulties in coordinating geographically separate organizations, which may be subject to additional complications resulting from being geographically distant from our other operations;
 
  •  failure to identify or assess the magnitude of certain liabilities we are assuming in the acquisition, which could result in unexpected litigation or regulatory exposure, unfavorable accounting treatment, unexpected increases in taxes due, a loss of anticipated tax benefits or other adverse effects on our business, operating results or financial condition;
 
  •  failure to realize the anticipated increase in our revenues due to the acquisition if customers adjust their purchasing decisions and allocate more market share to our competitors;
 
  •  difficulties or delays in incorporating acquired technologies or products with our existing product lines and maintaining uniform standards, controls, processes and policies;
 
  •  failure to successfully manage relationships with our combined supplier and customer base;
 
  •  the impact of the March 2011 earthquakes, tsunami and related events in Japan on HGST’s business, component supply or Japan facilities;
 
  •  difficulties integrating and harmonizing business systems;
 
  •  difficulties in modifying HGST’s existing accounting and internal control systems to comply with Section 404 of the Sarbanes-Oxley Act of 2002, to which HGST is not currently subject, which could adversely impact the effectiveness of internal control over financial reporting for the combined company; and
 
  •  the loss of key employees.
 
If we are not able to successfully integrate HGST’s business and technology into our operations, the anticipated benefits and efficiencies of the planned acquisition may not be realized fully or at all, or may take longer to realize than


13


Table of Contents

expected, and our ability to compete, our revenue and gross margins and our results of operations may be adversely affected.
 
The integration of HGST may result in significant restructuring charges that could adversely affect the financial results of the combined company.
 
The financial results of the combined company may be adversely affected by cash expenses and non-cash accounting charges incurred in connection with the combination. The amount and timing of these possible charges are not yet known. The price of our common stock following the acquisition could decline to the extent the combined company’s financial results are materially affected by these charges.
 
The financing of our planned HGST acquisition will dilute our stockholders’ ownership interest in the company, and may have an adverse impact on our liquidity, limit our flexibility in responding to other business opportunities and increase our vulnerability to adverse economic and industry conditions.
 
Our planned acquisition of HGST will be financed by a combination of the issuance of additional shares of our common stock, the use of a significant amount of our cash on hand and the incurrence of a significant amount of indebtedness. The issuance of additional shares of our common stock will dilute your ownership interest in the company. The use of cash on hand and indebtedness to finance the acquisition will reduce our liquidity and could cause us to place more reliance on cash flow from operations to pay principal and interest on our debt, thereby reducing the availability of our cash flow for operations and development activities. The credit agreement we expect to enter into with respect to the indebtedness we will incur to finance the planned acquisition contains restrictive covenants, including financial covenants requiring us to maintain specified financial ratios. Our ability to meet these restrictive covenants can be affected by events beyond our control. The indebtedness and these restrictive covenants will also have the effect, among other things, of impairing our ability to obtain additional financing, if needed, limiting our flexibility in the conduct of our business and making us more vulnerable to economic downturns and adverse competitive and industry conditions. In addition, a breach of the restrictive covenants could result in an event of default under the credit agreement we will enter into with respect to the indebtedness, which, if not cured or waived, could result in the indebtedness becoming immediately due and payable and could have a material adverse effect on our business, financial condition or operating results.
 
Adverse global economic conditions and credit market uncertainty could harm our business, results of operations and financial condition.
 
Adverse global economic conditions and uncertain conditions in the credit market have had, and in the future could have, a significant adverse effect on our company and on the storage industry as a whole. Some of the risks and uncertainties we face as a result of these global economic and credit market conditions include the following:
 
  •  Volatile Demand.  Negative or uncertain global economic conditions could cause many of our direct and indirect customers to delay or reduce their purchases of our products and systems containing our products. In addition, many of our customers rely on credit financing to purchase our products. If negative conditions in the global credit markets prevent our customers’ access to credit, product orders may decrease, which could result in lower revenue. Likewise, if our suppliers, sub-suppliers and sub-contractors (collectively referred to as “suppliers”) face challenges in obtaining credit, in selling their products or otherwise in operating their businesses, they may be unable to offer the materials we use to manufacture our products. These actions could result in reductions in our revenue and increased operating costs, which could adversely affect our business, results of operations and financial condition.
 
  •  Restructuring Activities.  If demand slows significantly as a result of a deterioration in economic conditions or otherwise, we may need to execute restructuring activities to realign our cost structure with softening demand. The occurrence of restructuring activities could result in impairment charges and other expenses, which could adversely impact our results of operations or financial condition.
 
  •  Credit Volatility and Loss of Receivables.  We extend credit and payment terms to some of our customers. In addition to ongoing credit evaluations of our customers’ financial condition, we traditionally seek to mitigate our credit risk by purchasing credit insurance on certain of our accounts receivable balances. As a result of the


14


Table of Contents

  continued uncertainty and volatility in global economic conditions, however, we may find it increasingly difficult to be able to insure these accounts receivable. We could suffer significant losses if a customer whose accounts receivable we have not insured, or have underinsured, fails and is unable to pay us. Additionally, negative or uncertain global economic conditions increase the risk that if a customer whose accounts receivable we have insured fails, the financial condition of the insurance carrier for such customer account may have also deteriorated such that it cannot cover our loss. A significant loss of an accounts receivable that we cannot recover through credit insurance would have a negative impact on our financial results.
 
  •  Impairment Charges.  Negative or uncertain global economic conditions could result in circumstances, such as a sustained decline in our stock price and market capitalization or a decrease in our forecasted cash flows such that they are insufficient, indicating that the carrying value of our long-lived assets or goodwill may be impaired. If we are required to record a significant charge to earnings in our consolidated financial statements because an impairment of our long-lived assets or goodwill is determined, our results of operations will be adversely affected.
 
We participate in a highly competitive industry that is subject to the risk of declining average selling prices (“ASPs”), volatile gross margins and significant shifts in market share, all of which could adversely affect our operating results.
 
Demand for our hard drives depends in large part on the demand for systems manufactured by our customers and on storage upgrades to existing systems. The demand for systems has been volatile in the past and often has had an exaggerated effect on the demand for hard drives in any given period. As a result, the hard drive market has experienced periods of excess capacity, which can lead to liquidation of excess inventories and more intense price competition. If more intense price competition occurs, we may be forced to lower prices sooner and more than expected, which could result in lower ASPs, revenue and gross margins. Our ASPs and gross margins also tend to decline when there is a shift in the mix of product sales, and sales of lower priced products increase relative to those of higher priced products. In addition, rapid technological changes often reduce the volume and profitability of sales of existing products and increase the risk of inventory obsolescence. These factors, along with others, may result in significant shifts in market share among the industry’s major participants.
 
Our failure to accurately forecast market and customer demand for our products, or to quickly adjust to forecast changes, could adversely affect our business and financial results or operating efficiencies.
 
The data storage industry faces difficulties in accurately forecasting market and customer demand for its products. The variety and volume of products we manufacture is based in part on these forecasts. Accurately forecasting demand has become increasingly difficult for us, our customers and our suppliers in light of the volatility in global economic conditions and a recent shift from air to ocean freight in response to increased transportation costs, which requires additional lead times. In addition, because hard drives are designed to be largely substitutable, our demand forecasts may be impacted significantly by the strategic actions of our competitors. As forecasting demand becomes more difficult, the risk that our forecasts are not in line with demand increases. If our forecasts exceed actual market demand, then we could experience periods of product oversupply and price decreases, which could impact our financial performance. If market demand increases significantly beyond our forecasts or beyond our ability to add manufacturing capacity, then we may not be able to satisfy customer product needs, which could result in a loss of market share if our competitors are able to meet customer demands.
 
We experience significant sales seasonality and cyclicality, which could cause our operating results to fluctuate.
 
Sales of computer systems, storage subsystems and consumer electronics tend to be seasonal and cyclical, and therefore we expect to continue to experience seasonality and cyclicality in our business as we respond to variations in our customers’ demand for hard drives. In the desktop, mobile, CE and retail markets, seasonality is partially attributable to the increase in sales of PCs and CE devices during the back-to-school and winter holiday seasons. As such, we anticipate that sales of our products will continue to be lower during the second half of our fiscal year. However, recently we have experienced stronger-than-anticipated demand partially driven by the increased adoption of sea freight in the PC supply chain. In the enterprise market our sales are seasonal because of the capital budgeting and purchasing cycles of our end users. However, changes in seasonal and cyclical patterns have made it, and could continue to make it, more difficult for us to forecast demand, especially in the current macroeconomic environment. Changes in the product or channel mix of our business can also impact seasonal and cyclical patterns, adding complexity in forecasting demand. Seasonality and


15


Table of Contents

cyclicality also may lead to higher volatility in our stock price. It is difficult for us to evaluate the degree to which seasonality and cyclicality may affect our stock price or business in future periods because of the rate and unpredictability of product transitions and new product introductions and macroeconomic conditions.
 
Our customers’ demand for storage capacity may not continue to grow at current industry estimates, which may lower the prices our customers are willing to pay for our products or put us at a disadvantage to competing technologies.
 
Our customers’ demand for storage capacity may not continue to grow at current industry estimates as a result of:
 
  •  Mobile Devices.  There has been a recent rapid growth in CE devices that do not contain a hard drive such as tablet computers and smartphones. While tablet computers and smartphones provide many of the same capabilities as PCs, the extent to which they will displace or materially affect the demand for PCs is uncertain. If device-makers are successful in achieving customer acceptance of these devices as a replacement for traditional computing applications that contain hard drives, or if we are not successful in adapting our product offerings to include alternative storage solutions that address these devices, then demand for our products may decrease.
 
  •  Cloud Computing.  Consumers traditionally have stored their data on their PC, often supplemented with personal external storage devices. Most businesses also include similar local storage as a primary or secondary storage location. This storage is typically provided by hard disk drives. Recently, cloud computing has emerged whereby applications and data are hosted, accessed and processed through a third-party provider over a broadband Internet connection, potentially reducing or eliminating the need for, among other things, significant storage inside the accessing computer. This trend could cause the market for disk drives in computers to decline over time, which could harm our business to the extent this decline is not offset by the sale of our products to customers who provide cloud computing services.
 
Demand for our products also could be negatively impacted by developments in the regulation and enforcement of digital rights management, the emergence of processes such as data deduplication and storage virtualization, economic conditions, and the rate of increase in areal density exceeding the increase in our customers’ demand for storage capacity. These factors could lead to our customers’ storage capacity needs being satisfied at lower prices with lower capacity hard drives or solid-state storage products that we do not offer, thereby decreasing our revenue or putting us at a disadvantage to competing storage technologies. As a result, even with increasing aggregate demand for storage capacity, if we fail to anticipate or timely respond to these developments in the demand for storage, our ASPs could decline, which could adversely affect our operating results.
 
Selling to the retail market is an important part of our business, and if we fail to maintain and grow our market share or gain market acceptance of our branded products, our operating results could suffer.
 
Selling branded products is an important part of our business, and as our branded products revenue increases as a portion of our overall revenue, our success in the retail market becomes increasingly important to our operating results. Our success in the retail market depends in large part on our ability to maintain our brand image and corporate reputation and to expand into and gain market acceptance of our products in multiple channels. Adverse publicity, whether or not justified, or allegations of product quality issues, even if false or unfounded, could tarnish our reputation and cause our customers to choose products offered by our competitors. In addition, the proliferation of new methods of mass communication facilitated by the Internet makes it easier for false or unfounded allegations to adversely affect our brand image and reputation. If customers no longer maintain a preference for WD®-brand products, our operating results may be adversely affected.
 
Sales in the distribution channel are important to our business, and if we fail to respond to demand changes in distribution markets or if distribution markets for hard drives weaken, our operating results could suffer.
 
Our distribution customers typically sell to small computer manufacturers, dealers, systems integrators and other resellers. We face significant competition in this channel as a result of limited product qualification programs and a significant focus on price and availability of product. In addition, the PC market is experiencing a shift to notebook and other mobile devices and, as a result, more computing devices are being delivered to the market as complete systems, which could weaken the distribution market. If we fail to respond to changes in demand in the distribution market, our operating results could suffer. Additionally, if the distribution market weakens as a result of a slowing PC growth rate,


16


Table of Contents

technology transitions or a significant change in consumer buying preference, or if we experience significant price declines due to demand changes in the distribution channel, then our operating results would be adversely affected.
 
Loss of market share with or by a key customer, or consolidation among our customer base, could harm our operating results.
 
During the year ended July 1, 2011, a large percentage of our revenue, 49%, came from sales to our top 10 customers. These customers have a variety of suppliers to choose from and therefore can make substantial demands on us, including demands on product pricing and on contractual terms, which often results in the allocation of risk to us as the supplier. Our ability to maintain strong relationships with our principal customers is essential to our future performance. If we lose a key customer, if any of our key customers reduce their orders of our products or require us to reduce our prices before we are able to reduce costs, if a customer is acquired by one of our competitors or if a key customer suffers financial hardship, our operating results would likely be harmed.
 
Additionally, if there is consolidation among our customer base, our customers may be able to command increased leverage in negotiating prices and other terms of sale, which could adversely affect our profitability. In addition, if, as a result of increased leverage, customer pressures require us to reduce our pricing such that our gross margins are diminished, we could decide not to sell our products to a particular customer, which could result in a decrease in our revenue. Consolidation among our customer base may also lead to reduced demand for our products, replacement of our products by the combined entity with those of our competitors and cancellations of orders, each of which could harm our operating results.
 
Our entry into additional storage markets increases the complexity of our business, and if we are unable to successfully adapt our business processes as required by these new markets, we will be at a competitive disadvantage and our ability to grow will be adversely affected.
 
As we expand our product line to sell into additional storage markets, the overall complexity of our business increases at an accelerated rate and we become subject to different market dynamics. The new markets into which we are expanding, or may expand, may have different characteristics from the markets in which we currently exist. These different characteristics may include, among other things, demand volume requirements, demand seasonality, product generation development rates, customer concentrations, warranty and product return policies and performance and compatibility requirements. Our failure to make the necessary adaptations to our business model to address these different characteristics, complexities and new market dynamics could adversely affect our operating results. For example, as we have previously disclosed, we entered the traditional enterprise market in November 2009. In addition to requiring significant capital expenditures, our entry into the traditional enterprise market adds complexity to our business that requires us to effectively adapt our business and management processes to address the unique challenges and different requirements of the traditional enterprise market, while maintaining a competitive operating cost model. If we fail to gain market acceptance in the traditional enterprise storage market, we will remain at a competitive disadvantage to the companies that succeed in this market and our ability to continue our growth will be negatively affected.
 
Expansion into new hard drive markets may cause our capital expenditures to increase, and if we do not successfully expand into new markets, our business may suffer.
 
To remain a significant supplier of hard drives, we will need to offer a broad range of hard drive products to our customers. We currently offer a variety of 3.5-inch or 2.5-inch hard drives for the desktop, mobile, enterprise, CE and external storage markets. However, demand for hard drives may shift to products in form factors or with interfaces that our competitors offer but which we do not. Expansion into other hard drive markets and resulting increases in manufacturing capacity requirements may require us to make substantial additional investments in part because our operations are largely vertically integrated now that we manufacture heads and magnetic media for use in many of the hard drives we manufacture. If we fail to successfully expand into new hard drive markets with products that we do not currently offer, we may lose business to our competitors who offer these products.

Table of Contents

Our vertical integration of head and magnetic media manufacturing makes us dependent on our ability to timely and cost-effectively develop heads and magnetic media with leading technology and overall quality, and creates additional capital expenditure costs and asset utilization risks to our business.
 
Under our business plan, we are developing and manufacturing a substantial portion of the heads and magnetic media used in the hard drive products we manufacture. Consequently, we are more dependent upon our own development and execution efforts and less able to take advantage of head and magnetic media technologies developed by other manufacturers. Technology transition for head and magnetic media designs is critical to increasing our volume production of heads and magnetic media. There can be no assurance, however, that we will be successful in timely and cost-effectively developing and manufacturing heads or magnetic media for products using future technologies. We also may not effectively transition our head or magnetic media design and technology to achieve acceptable manufacturing yields using the technologies necessary to satisfy our customers’ product needs, or we may encounter quality problems with the heads or magnetic media we manufacture. If we are unable to timely and cost-effectively develop heads and magnetic media with leading technology and overall quality, our ability to sell our products may be significantly diminished, which could materially and adversely affect our business and financial results.
 
In addition, as a result of our vertical integration of head and magnetic media manufacturing, we make more capital investments and carry a higher percentage of fixed costs than we would if we were not vertically integrated. If our overall level of production decreases for any reason, and we are unable to reduce our fixed costs to match sales, our head or magnetic media manufacturing assets may face under-utilization that may impact our operating results. We are therefore subject to additional risks related to overall asset utilization, including the need to operate at high levels of utilization to drive competitive costs and the need for assured supply of components that we do not manufacture ourselves. If we do not adequately address the challenges related to our head or magnetic media manufacturing operations, our ongoing operations could be disrupted, resulting in a decrease in our revenue or profit margins and negatively impacting our operating results.
 
We make significant investments in research and development to improve our technology and develop new technologies, and unsuccessful investments could materially adversely affect our business, financial condition and results of operations.
 
Over the past several years, our business strategy has been to derive a competitive advantage by moving from being a follower of new technologies to being a leader in the innovation and development of new technologies. This strategy requires us to make significant investments in research and development and, in attempting to remain competitive, we may increase our capital expenditures and expenses above our historical run-rate model. There can be no assurance that these investments will result in viable technologies or products, or if these investments do result in viable technologies or products, that they will be profitable or accepted by the market. Significant investments in unsuccessful research and development efforts could materially adversely affect our business, financial condition and results of operations. In addition, increased investments in technology could cause our cost structure to fall out of alignment with demand for our products, which would have a negative impact on our financial results.
 
Current or future competitors may gain a technology advantage or develop an advantageous cost structure that we cannot match.
 
It may be possible for our current or future competitors to gain an advantage in product technology, manufacturing technology, or process technology, which may allow them to offer products or services that have a significant advantage over the products and services that we offer. Advantages could be in capacity, performance, reliability, serviceability, or other attributes. A competitive cost structure for our products, including critical components, labor and overhead, is also critical to the success of our business. We may be at a competitive disadvantage to any companies that are able to gain a technological or cost structure advantage.
 
Further industry consolidation could provide competitive advantages to our competitors.
 
The hard drive industry has experienced consolidation over the past several years. Consolidation by our competitors may enhance their capacity, abilities and resources and lower their cost structure, causing us to be at a competitive disadvantage.

Some of our competitors with diversified business units outside the hard drive industry may over extended periods of time sell hard drives at prices that we cannot profitably match.
 
Some of our competitors earn a significant portion of their revenue from business units outside the hard drive industry. Because they do not depend solely on sales of hard drives to achieve profitability, they may sell hard drives at lower prices and operate their hard drive business unit at a loss over an extended period of time while still remaining profitable overall. In addition, if these competitors can increase sales of non-hard drive products to the same customers, they may benefit from selling their hard drives at lower prices. Our operating results may be adversely affected if we cannot successfully compete with the pricing by these companies.
 
If we fail to qualify our products with our customers or if product life cycles lengthen, it may have a significant adverse impact on our sales and margins.
 
We regularly engage in new product qualification with our customers. Once a product is accepted for qualification testing, failures or delays in the qualification process can result in delayed or reduced product sales, reduced product margins caused by having to continue to offer a more costly current generation product, or lost sales to that customer until the next generation of products is introduced. The effect of missing a product qualification opportunity is magnified by the limited number of high volume OEMs, which continue to consolidate their share of the storage markets. Likewise, if product life cycles lengthen, we may have a significantly longer period to wait before we have an opportunity to qualify a new product with a customer, which could reduce our profits because we expect declining gross margins on our current generation products as a result of competitive pressures.
 
We are subject to risks related to product defects, which could result in product recalls or epidemic failures and could subject us to warranty claims in excess of our warranty provisions or which are greater than anticipated.
 
We warrant the majority of our products for periods of one to five years. We test our hard drives in our manufacturing facilities through a variety of means. However, there can be no assurance that our testing will reveal defects in our products, which may not become apparent until after the products have been sold into the market. Accordingly, there is a risk that product defects will occur, which could require a product recall. Product recalls can be expensive to implement and, if a product recall occurs during the product’s warranty period, we may be required to replace the defective product. Moreover, there is a risk that product defects may trigger an epidemic failure clause in a customer agreement. If an epidemic failure occurs, we may be required to replace or refund the value of the defective product and to cover certain other costs associated with the consequences of the epidemic failure. In addition, a product recall or epidemic failure may damage our reputation or customer relationships, and may cause us to lose market share with our customers, including our OEM and ODM customers.
 
Our standard warranties contain limits on damages and exclusions of liability for consequential damages and for misuse, improper installation, alteration, accident or mishandling while in the possession of someone other than us. We record an accrual for estimated warranty costs at the time revenue is recognized. We may incur additional operating expenses if our warranty provision does not reflect the actual cost of resolving issues related to defects in our products, whether as a result of a product recall, epidemic failure or otherwise. If these additional expenses are significant, it could adversely affect our business, financial condition and operating results.
 
Dependence on a limited number of qualified suppliers of components and manufacturing equipment could lead to delays, lost revenue or increased costs.
 
Our future operating results may depend substantially on our suppliers’ ability to timely qualify their components in our programs, and their ability to supply us with these components in sufficient volumes to meet our production requirements. A number of the components that we use are available from only a single or limited number of qualified suppliers, and may be used across multiple product lines. As such, the success of our products depends on our ability to gain access to and integrate parts from reliable component suppliers. To do so, we must maintain effective relationships with our supply base to source our component needs, develop compatible technology, and maintain continuity of supply at reasonable costs. If we fail to maintain effective relationships with our supply base, or if we fail to integrate components from our suppliers effectively, this may adversely affect our ability to develop and deliver the best products to our customers and our profitability could suffer.

Table of Contents

Certain equipment and consumables we use in our manufacturing or testing processes are available only from a limited number of suppliers. Some of this equipment and consumables use materials that at times could be in short supply. If these materials are not available, or are not available in the quantities we require for our manufacturing and testing processes, our ability to manufacture our products could be impacted, and we could suffer significant loss of revenue.
 
Each of the following could also significantly harm our operating results:
 
  •  an unwillingness of a supplier to supply such components or equipment to us;
 
  •  consolidation of key suppliers;
 
  •  failure of a key supplier’s business process;
 
  •  a key supplier’s or sub-supplier’s inability to access credit necessary to operate its business; or
 
  •  failure of a key supplier to remain in business, to remain an independent merchant supplier, or to adjust to market conditions.
 
Shortages of commodity materials or commodity components, price volatility, or use by other industries of materials and components used in the hard drive industry, may negatively impact our operating results.
 
Increases in the cost for certain commodity materials or commodity components may increase our costs of manufacturing and transporting hard drives and key components. Shortages of commodity components such as DRAM and NAND flash, or commodity materials such as glass substrates, stainless steel, aluminum, nickel, neodymium, ruthenium, platinum or cerium, may increase our costs and may result in lower operating margins if we are unable to find ways to mitigate these increased costs. We or our suppliers acquire certain precious metals and rare earth metals like ruthenium, platinum, neodymium and cerium, critical to the manufacture of components in our products from a number of countries, including the People’s Republic of China. The government of China or any other nation may impose regulations, quotas or embargoes upon these metals that would restrict the worldwide supply of such metals and/or increase their cost, both of which could negatively impact our operating results until alternative suppliers are sourced. Furthermore, if other high volume industries increase their demand for materials or components used in our products, our costs may further increase, which could have an adverse effect on our operating margins. In addition, shortages in other commodity components and materials used in our customers’ products could result in a decrease in demand for our products, which would negatively impact our operating results. The volatility in the cost of oil also affects our costs and may result in lower operating margins if we are unable to pass these increased costs on to our customers.
 
Contractual commitments with component suppliers may result in us paying increased charges and cash advances for such components or may cause us to have inadequate or excess component inventory.
 
To reduce the risk of component shortages, we attempt to provide significant lead times when buying components, which may subject us to cancellation charges if we cancel orders as a result of technology transitions or changes in our component needs. In addition, we may from time to time enter into contractual commitments with component suppliers in an effort to increase and stabilize the supply of those components and enable us to purchase such components at favorable prices. Some of these commitments may require us to buy a substantial number of components from the supplier or make significant cash advances to the supplier; however, these commitments may not result in a satisfactory increase or stabilization of the supply of such components. Furthermore, as a result of uncertain global economic conditions, our ability to forecast our requirements for these components has become increasingly difficult, therefore increasing the risk that our contractual commitments may not meet our actual supply requirements, which could cause us to have inadequate or excess component inventory and adversely affect our operating results and increase our operating costs.
 
Failure by certain suppliers to effectively and efficiently develop and manufacture components, technology or production equipment for our products may adversely affect our operations.
 
We rely on suppliers for various component parts that we integrate into our hard drives but do not manufacture ourselves, such as semiconductors, motors, flex circuits and suspensions. Likewise, we rely on suppliers for certain


20


Table of Contents

technology and equipment necessary for advanced development technology for future products. Some of these components, and most of this technology and production equipment, must be specifically designed to be compatible for use in our products or for developing and manufacturing our future products, and are only available from a limited number of suppliers, some of with whom we are sole sourced. We are therefore dependent on these suppliers to be able and willing to dedicate adequate engineering resources to develop components that can be successfully integrated with our products, and technology and production equipment that can be used to develop and manufacture our next-generation products efficiently. The failure of these suppliers to effectively and efficiently develop and manufacture components that can be integrated into our products or technology and production equipment that can be used to develop or manufacture next generation products may cause us to experience inability or delay in our manufacturing and shipment of hard drive products, our expansion into new technology and markets, or our ability to remain competitive with alternative storage technologies, therefore adversely affecting our business and financial results.
 
Changes in product life cycles could adversely affect our financial results.
 
If product life cycles lengthen, we may need to develop new technologies or programs to reduce our costs on any particular product to maintain competitive pricing for that product. If product life cycles shorten, it may result in an increase in our overall expenses and a decrease in our gross margins, both of which could adversely affect our operating results. In addition, shortening of product life cycles also makes it more difficult to recover the cost of product development before the product becomes obsolete. Our failure to recover the cost of product development in the future could adversely affect our operating results.
 
A fundamental change in recording technology could result in significant increases in our operating expenses and could put us at a competitive disadvantage.
 
Historically, when the industry experiences a fundamental change in technology, any manufacturer that fails to successfully and timely adjust its designs and processes to accommodate the new technology fails to remain competitive. There are some revolutionary technologies, such as current-perpendicular-to-plane giant magnetoresistance, shingle magnetic recording, energy assisted magnetic recording, patterned magnetic media and advanced signal processing, that if implemented by a competitor on a commercially viable basis ahead of the industry, could put us at a competitive disadvantage. As a result of these technology shifts, we could incur substantial costs in developing new technologies, such as heads, magnetic media, and tools to remain competitive. If we fail to successfully implement these new technologies, or if we are significantly slower than our competitors at implementing new technologies, we may not be able to offer products with capacities that our customers desire.
 
The difficulty of introducing hard drives with higher levels of areal density and the challenges of reducing other costs may impact our ability to achieve historical levels of cost reduction.
 
Storage capacity of the hard drive, as manufactured by us, is determined by the number of disks and each disk’s areal density. Areal density is a measure of the amount of magnetic bits that can be stored on the recording surface of the disk. Generally, the higher the areal density, the more information can be stored on a single platter. Higher areal densities require existing head and magnetic media technology to be improved or new technologies developed to accommodate more data on a single disk. Historically, we have been able to achieve a large percentage of cost reduction through increases in areal density. Increases in areal density mean that the average drive we sell has fewer heads and disks for the same capacity and, therefore, may result in a lower component cost. However, increasing areal density has become more difficult in the hard drive industry. If we are not able to increase areal density at the same rate as our competitors or at a rate that is expected by our customers, we may be required to include more components in our drives to meet demand without corresponding incremental revenue, which could negatively impact our operating margins and make achieving historical levels of cost reduction difficult or unlikely. Additionally, increases in areal density may require us to make further capital expenditures on items such as new testing equipment needed as a result of an increased number of GB per platter. Our inability to achieve cost reductions could adversely affect our operating results.

If we do not properly manage technology transitions and new product development, our competitiveness and operating results may be negatively affected.
 
The storage markets in which we offer our products continuously undergo technology transitions which we must anticipate and adapt our products to address in a timely manner. If we fail to implement these new technologies successfully, or if we are slower than our competitors at implementing new technologies, we may not be able to competitively offer products that our customers desire, which could harm our operating results.
 
In addition, the success of our new product introductions depends on a number of other factors, including
 
  •  difficulties faced in manufacturing ramp;
 
  •  implementing at an acceptable cost product features expected by our customers;
 
  •  market acceptance/qualification;
 
  •  effective management of inventory levels in line with anticipated product demand; and
 
  •  quality problems or other defects in the early stages of new product introduction that were not anticipated in the design of those products.
 
Our business may suffer if we fail to successfully anticipate and manage these issues associated with our product development.
 
If we fail to develop and introduce new hard drives that are competitive against alternative storage technologies, our business may suffer.
 
Our success depends in part on our ability to develop and introduce new products in a timely manner in order to keep pace with competing technologies. Alternative storage technologies like solid-state storage technology have successfully served digital entertainment markets for products such as digital cameras, MP3 players, USB flash drives, mobile phones and tablet devices that cannot be economically serviced using hard drive technology. Advances in semiconductor technology have resulted in solid-state storage emerging as a technology that is competitive with hard drives for high performance needs in advanced digital computing markets such as enterprise servers and storage. Solid-state storage is produced by large semiconductor companies who can then sell their storage products at lower prices while still remaining profitable overall. This can help them improve their market share at the expense of the competition. In addition, these semiconductor companies may choose to supply companies like us with semiconductor media at prices that make it difficult, if not impossible, for us to compete with them on a profitable basis. As a result, there can be no assurance that we will be successful in anticipating and developing new products for the desktop, mobile, enterprise, CE and external storage markets in response to solid-state storage, as well as other competing technologies. If our hard drive technology fails to offer higher capacity, performance and reliability with lower cost-per-gigabyte than solid-state storage for the desktop, mobile, enterprise, CE and external storage markets, we will be at a competitive disadvantage to companies using semiconductor technology to serve these markets and our business will suffer.
 
Our manufacturing operations, and those of certain of our suppliers and customers, are concentrated in large, purpose-built facilities, which subjects us to substantial risk of damage or loss if operations at any of these facilities are disrupted.
 
As a result of our cost structure and strategy of vertical integration, we conduct our manufacturing operations at large, high volume, purpose-built facilities. For example, a substantial majority of our requirement for heads is satisfied by wafers fabricated in our Fremont, California facility. Also, we manufacture the majority of our substrates for magnetic media in our Johor, Malaysia facility, and we finish a majority of our magnetic media in our facilities in Penang, Malaysia and Tuas, Singapore. A majority of our high volume hard drive manufacturing operations are conducted in our two facilities in Thailand, with the balance conducted in our Kuala Lumpur, Malaysia facility and the facilities of our contract manufacturers in Asia, Brazil, Europe and the United States. As part of our planned acquisition of HGST, we will also acquire manufacturing facilities located in Japan, China and the Philippines (as well as additional factories in Singapore, Thailand and Malaysia). The manufacturing facilities of many of our customers, our suppliers and our customers’ suppliers are also concentrated in certain geographic locations in Asia and elsewhere. A localized health risk affecting our employees at these facilities or the staff of our or our customers’ other suppliers, such as the spread of the Influenza A (H1N1) or a new pandemic influenza, could impair the total volume of hard drives that we are able to manufacture and/or

sell, which would result in substantial harm to our operating results. Similarly, a fire, flood, earthquake, tsunami or other disaster, condition or event such as political instability, civil unrest or a power outage that adversely affects any of these facilities would significantly affect our ability to manufacture and/or sell hard drives, which would result in a substantial loss of sales and revenue and a substantial harm to our operating results.
 
For example, while we presently do not have manufacturing operations located in Japan, we do source certain components from suppliers with facilities in Japan. The March 2011 earthquakes, tsunami and related events in Japan, including the resulting power outages, have affected and may continue to affect the supply of certain components used in the production of hard drives and systems that include hard drives. The development of events in Japan has, however, been fluid and unpredictable. If we experience any shortage of components of acceptable quality, or any interruption in the supply of required components we cannot promptly obtain from alternative sources at acceptable prices, our operating results would be adversely affected. In addition, even if the events in Japan do not adversely affect our component supply, they may adversely affect the supply of other components our customers use in their systems, which could negatively impact demand for our products and, therefore, our revenues.
 
Manufacturing outside the United States and marketing our products globally subjects us to numerous risks.
 
We are subject to risks associated with our global manufacturing operations and global marketing efforts, including:
 
  •  obtaining requisite U.S. and foreign governmental permits and approvals;
 
  •  currency exchange rate fluctuations or restrictions;
 
  •  political instability and civil unrest;
 
  •  limited transportation availability, delays, and extended time required for shipping, which risks may be compounded in periods of price declines;
 
  •  higher freight rates;
 
  •  labor problems;
 
  •  trade restrictions or higher tariffs;
 
  •  copyright levies or similar fees or taxes imposed in European and other countries;
 
  •  exchange, currency and tax controls and reallocations;
 
  •  increasing labor and overhead costs; and
 
  •  loss or non-renewal of favorable tax treatment under agreements or treaties with foreign tax authorities.
 
Terrorist attacks may adversely affect our business and operating results.
 
The continued threat of terrorist activity and other acts of war or hostility have created uncertainty in the financial and insurance markets and have significantly increased the political, economic and social instability in some of the geographic areas in which we operate. Additionally, it is uncertain what impact the reactions to such acts by various governmental agencies and security regulators worldwide will have on shipping costs. Acts of terrorism, either domestically or abroad, could create further uncertainties and instability. To the extent this results in disruption or delays of our manufacturing capabilities or shipments of our products, our business, operating results and financial condition could be adversely affected.
 
Sudden disruptions to the availability of freight lanes could have an impact on our operations.
 
We generally ship our products to our customers, and receive shipments from our suppliers, via air, ocean or land freight. The sudden unavailability or disruption of cargo operations or freight lanes, such as due to labor difficulties or disputes, severe weather patterns or other natural disasters, or political instability or civil unrest, could impact our operating results by impairing our ability to timely and efficiently deliver our products.

We are vulnerable to system failures or attacks, which could harm our business.
 
We are heavily dependent on our technology infrastructure, among other functions, to operate our factories, sell our products, fulfill orders, manage inventory and bill, collect and make payments. Our systems are vulnerable to damage or interruption from natural disasters, power loss, telecommunication failures, computer viruses, computer denial-of-service attacks and other events. Our business is also subject to break-ins, sabotage and intentional acts of vandalism by third parties as well as employees. Despite any precautions we may take, such problems could result in, among other consequences, interruptions in our business, which could harm our reputation and financial condition.
 
If we fail to identify, manage, complete and integrate acquisitions, investment opportunities or other significant transactions, it may adversely affect our future results.
 
As part of our growth strategy, we may pursue acquisitions of, investment opportunities in or other significant transactions with companies that are complementary to our business. In order to pursue this strategy successfully, we must identify attractive acquisition or investment opportunities, successfully complete the transaction, some of which may be large and complex, and manage post-closing issues such as integration of the acquired company or employees. We may not be able to identify or complete appealing acquisition or investment opportunities given the intense competition for these transactions. Even if we identify and complete suitable corporate transactions, we may not be able to successfully address any integration challenges in a timely manner, or at all. If we fail to successfully integrate an acquisition, we may not realize all or any of the anticipated benefits of the acquisition, and our future results of operations could be adversely affected.
 
If we are unable to retain or hire key staff and skilled employees our business results may suffer.
 
Our success depends upon the continued contributions of our key staff and skilled employees, many of whom would be extremely difficult to replace. Global competition for skilled employees in the data storage industry is intense and, as we attempt to move to a position of technology leadership in the storage industry, our business success becomes increasingly dependent on our ability to retain our key staff and skilled employees as well as attract, integrate and retain new skilled employees. Volatility or lack of positive performance in our stock price and the overall markets may adversely affect our ability to retain key staff or skilled employees who have received equity compensation. Additionally, because a substantial portion of our key employees’ compensation is placed “at risk” and linked to the performance of our business, when our operating results are negatively impacted by global economic conditions, we are at a competitive disadvantage for retaining and hiring key staff and skilled employees versus other companies that pay a relatively higher fixed salary. If we are unable to retain our existing key staff or skilled employees, or hire and integrate new key staff or skilled employees, or if we fail to implement succession plans for our key staff, our operating results would likely be harmed.
 
The nature of our business and our reliance on intellectual property and other proprietary information subjects us to the risk of significant litigation.
 
The data storage industry has been characterized by significant litigation. This includes litigation relating to patent and other intellectual property rights, product liability claims and other types of litigation. Litigation can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of litigation are inherently uncertain and may result in adverse rulings or decisions. We may enter into settlements or be subject to judgments that may, individually or in the aggregate, have a material adverse effect on our business, financial condition or operating results.
 
We evaluate notices of alleged patent infringement and notices of patents from patent holders that we receive from time to time. If claims or actions are asserted against us, we may be required to obtain a license or cross-license, modify our existing technology or design a new non-infringing technology. Such licenses or design modifications can be extremely costly. In addition, we may decide to settle a claim or action against us, which settlement could be costly. We may also be liable for any past infringement. If there is an adverse ruling against us in an infringement lawsuit, an injunction could be issued barring production or sale of any infringing product. It could also result in a damage award equal to a reasonable royalty or lost profits or, if there is a finding of willful infringement, treble damages. Any of these results would increase our costs and harm our operating results.

Our reliance on intellectual property and other proprietary information subjects us to the risk that these key ingredients of our business could be copied by competitors.
 
Our success depends, in significant part, on the proprietary nature of our technology, including non-patentable intellectual property such as our process technology. If a competitor is able to reproduce or otherwise capitalize on our technology despite the safeguards we have in place, it may be difficult, expensive or impossible for us to obtain necessary legal protection. Also, the laws of some foreign countries may not protect our intellectual property to the same extent as do U.S. laws. In addition to patent protection of intellectual property rights, we consider elements of our product designs and processes to be proprietary and confidential. We rely upon employee, consultant and vendor non-disclosure agreements and contractual provisions and a system of internal safeguards to protect our proprietary information. However, any of our registered or unregistered intellectual property rights may be challenged or exploited by others in the industry, which might harm our operating results.
 
The costs of compliance with state, federal and international legal and regulatory requirements, such as environmental, labor, trade and tax regulations, and customers’ standards of corporate citizenship could cause an increase in our operating costs.
 
We may be or become subject to various state, federal and international laws and regulations governing our environmental, labor, trade and tax practices. These laws and regulations, particularly those applicable to our international operations, are or may be complex, extensive and subject to change. We will need to ensure that we and our component suppliers timely comply with such laws and regulations, which may result in an increase in our operating costs. For example, the European Union (“EU”) has enacted the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (“RoHS”) directive, which prohibits the use of certain substances in electronic equipment, and the Waste Electrical and Electronic Equipment (“WEEE”) directive, which obligates parties that place electrical and electronic equipment onto the market in the EU to put a clearly identifiable mark on the equipment, register with and report to EU member countries regarding distribution of the equipment, and provide a mechanism to take back and properly dispose of the equipment. Similar legislation may be enacted in other locations where we manufacture or sell our products. In addition, climate change and financial reform legislation in the United States is a significant topic of discussion and has generated and may continue to generate federal or other regulatory responses in the near future. If we or our component suppliers fail to timely comply with applicable legislation, our customers may refuse to purchase our products or we may face increased operating costs as a result of taxes, fines or penalties, which would have a materially adverse effect on our business, financial condition and operating results.
 
In connection with our compliance with such environmental laws and regulations, as well as our compliance with industry environmental initiatives, the standards of business conduct required by some of our customers, and our commitment to sound corporate citizenship in all aspects of our business, we could incur substantial compliance and operating costs and be subject to disruptions to our operations and logistics. In addition, if we were found to be in violation of these laws or noncompliant with these initiatives or standards of conduct, we could be subject to governmental fines, liability to our customers and damage to our reputation and corporate brand which could cause our financial condition or operating results to suffer.
 
Violation of applicable laws, including labor or environmental laws, and certain other practices by our suppliers could harm our business.
 
We expect our suppliers to operate in compliance with applicable laws and regulations, including labor and environmental laws, and to otherwise meet our required supplier standards of conduct. While our internal operating guidelines promote ethical business practices, we do not control our suppliers or their labor or environmental practices. The violation of labor, environmental or other laws by any of our suppliers, or divergence of a supplier’s business practices from those generally accepted as ethical in the United States, could harm our business by:
 
  •  interrupting or otherwise disrupting the shipment of our product components;
 
  •  damaging our reputation;
 
  •  forcing us to find alternate component sources;
 
  •  reducing demand for our products (for example, through a consumer boycott); or


25


Table of Contents

 
  •  exposing us to potential liability for our supplier’s wrongdoings.
 
Fluctuations in currency exchange rates as a result of our international operations may negatively affect our operating results.
 
Because we manufacture and sell our products abroad, our revenue, margins, operating costs and cash flows are impacted by fluctuations in foreign currency exchange rates. If the U.S. dollar exhibits sustained weakness against most foreign currencies, the U.S. dollar equivalents of unhedged manufacturing costs could increase because a significant portion of our production costs are foreign-currency denominated. Conversely, there would not be an offsetting impact to revenues since revenues are substantially U.S. dollar denominated. Additionally, we negotiate and procure some of our component requirements in U.S. dollars from Japanese and other non-U.S. based vendors. If the U.S. dollar continues to weaken against other foreign currencies, some of our component suppliers may increase the price they charge for their components in order to maintain an equivalent profit margin. If this occurs, it would have a negative impact on our operating results.
 
Prices for our products are substantially U.S. dollar denominated, even when sold to customers that are located outside the United States. Therefore, as a substantial portion of our sales are from countries outside the United States, fluctuations in currency exchanges rates, most notably the strengthening of the U.S. dollar against other foreign currencies, contribute to variations in sales of products in impacted jurisdictions and could adversely impact demand and revenue growth. In addition, currency variations can adversely affect margins on sales of our products in countries outside the United States.
 
We have attempted to manage the impact of foreign currency exchange rate changes by, among other things, entering into short-term, foreign exchange contracts. However, these contracts do not cover our full exposure and can be canceled by the counterparty if currency controls are put in place. Currently, we hedge the Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling with foreign exchange contracts.
 
Increases in our customers’ credit risk could result in credit losses and an increase in our operating costs.
 
Some of our OEM customers have adopted a subcontractor model that requires us to contract directly with companies, such as ODMs, that provide manufacturing and fulfillment services to our OEM customers. Because these subcontractors are generally not as well capitalized as our direct OEM customers, this subcontractor model exposes us to increased credit risks. Our agreements with our OEM customers may not permit us to increase our product prices to alleviate this increased credit risk. Additionally, as we attempt to expand our OEM and distribution channel sales into emerging economies such as Brazil, Russia, India and China, the customers with the most success in these regions may have relatively short operating histories, making it more difficult for us to accurately assess the associated credit risks. Any credit losses we may suffer as a result of these increased risks, or as a result of credit losses from any significant customer, would increase our operating costs, which may negatively impact our operating results.
 
Our operating results fluctuate, sometimes significantly, from period to period due to many factors, which may result in a significant decline in our stock price.
 
Our quarterly operating results may be subject to significant fluctuations as a result of a number of other factors including:
 
  •  the timing of orders from and shipment of products to major customers;
 
  •  our product mix;
 
  •  changes in the prices of our products;
 
  •  manufacturing delays or interruptions;
 
  •  acceptance by customers of competing products in lieu of our products;
 
  •  variations in the cost of and lead times for components for our products;
 
  •  limited availability of components that we obtain from a single or a limited number of suppliers;
 
  •  seasonal and other fluctuations in demand for PCs often due to technological advances; and


26


Table of Contents

 
  •  availability and rates of transportation.
 
We often ship a high percentage of our total quarterly sales in the third month of the quarter, which makes it difficult for us to forecast our financial results before the end of the quarter. As a result of the above or other factors, our forecast of operating results for the quarter may differ materially from our actual financial results. If our results of operations fail to meet the expectations of analysts or investors, it could cause an immediate and significant decline in our stock price.
 
We have made and continue to make a number of estimates and assumptions relating to our consolidated financial reporting, and actual results may differ significantly from our estimates and assumptions.
 
We have made and continue to make a number of estimates and assumptions relating to our consolidated financial reporting. The highly technical nature of our products and the rapidly changing market conditions with which we deal means that actual results may differ significantly from our estimates and assumptions. These changes have impacted our financial results in the past and may continue to do so in the future. Key estimates and assumptions for us include:
 
  •  price protection adjustments and other sales promotions and allowances on products sold to retailers, resellers and distributors;
 
  •  inventory adjustments for write-down of inventories to lower of cost or market value (net realizable value);
 
  •  reserves for doubtful accounts;
 
  •  accruals for product returns;
 
  •  accruals for warranty costs related to product defects;
 
  •  accruals for litigation and other contingencies;
 
  •  liabilities for unrecognized tax benefits; and
 
  •  expensing of stock-based compensation.
 
The market price of our common stock is volatile.
 
The market price of our common stock has been, and may continue to be, extremely volatile. Factors that may significantly affect the market price of our common stock include the following:

In addition, general economic conditions may cause the stock market to experience extreme price and volume fluctuations from time to time that particularly affect the stock prices of many high technology companies. These fluctuations often appear to be unrelated to the operating performance of the companies.
 
Securities class action lawsuits are often brought against companies after periods of volatility in the market price of their securities. A number of such suits have been filed against us in the past, and should any new lawsuits be filed, such matters could result in substantial costs and a diversion of resources and management’s attention.
 
Current economic conditions have caused us difficulty in adequately protecting our increased cash and cash equivalents from financial institution failures.
 
The uncertain global economic conditions and volatile investment markets have caused us to hold more cash and cash equivalents than we would hold under normal circumstances. Since there has been an overall increase in demand for low-risk, U.S. government-backed securities with a limited supply in the financial marketplace, we face increased difficulty in adequately protecting our increased cash and cash equivalents from possible sudden and unforeseeable failures by banks and other financial institutions. A failure of any of these financial institutions in which deposits exceed FDIC limits could have an adverse impact on our financial position.
 
If our internal controls are found to be ineffective, our financial results or our stock price may be adversely affected.
 
Our most recent evaluation resulted in our conclusion that as of July 1, 2011, in compliance with Section 404 of the Sarbanes-Oxley Act of 2002, our internal control over financial reporting was effective. We believe that we currently have adequate internal control procedures in place for future periods; however, if our internal control over financial reporting is found to be ineffective or if we identify a material weakness in our financial reporting, investors may lose confidence in the reliability of our financial statements, which may adversely affect our financial results or our stock price.
 
From time to time we may become subject to income tax audits or similar proceedings, and as a result we may incur additional costs and expenses or owe additional taxes, interest and penalties that may negatively impact our operating results.
 
We are subject to income taxes in the United States and certain foreign jurisdictions, and our determination of our tax liability is subject to review by applicable domestic and foreign tax authorities. For example, as we have previously disclosed, we are under examination by the Internal Revenue Service for certain fiscal years and in connection with that examination, we received Revenue Agent Reports seeking certain adjustments to income as disclosed in Part II, Item 8, Note 9 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Although we believe our tax positions are properly supported, the final timing and resolution of the notice of proposed adjustment and the audits are subject to significant uncertainty and could result in our having to pay amounts to the applicable tax authority in order to resolve examination of our tax positions, which could result in an increase or decrease of our current estimate of unrecognized tax benefits and may negatively impact our financial position, results of operations, net income or cash flows.

Not applicable.
 
Item 2.   Properties
 
In the first quarter of fiscal 2011, we began the process of relocating our corporate headquarters from Lake Forest, California to Irvine, California. The Irvine headquarters consist of approximately 365,000 square feet of leased space and house our management, research and development, administrative and sales staff. We continue to lease certain facilities in Lake Forest, California while we complete the relocation. The Lake Forest facilities consist of approximately 67,000 square feet of leased space and house certain engineering and administrative staff. In addition, we lease one facility in Aliso Viejo, California, consisting of approximately 34,000 square feet, which we use to house research and development, administrative and sales staff. We expect to complete the relocation and consolidation of our Lake Forest and Aliso Viejo functions to Irvine in the third quarter of fiscal 2012.

Planned Acquisition of Hitachi Global Storage Technologies
 
On March 7, 2011, we entered into a stock purchase agreement (the “Purchase Agreement”) with Hitachi, Ltd. (“Hitachi”), Viviti Technologies Ltd., until recently known as Hitachi Global Storage Technologies Holdings Pte. Ltd., a wholly owned subsidiary of Hitachi (“HGST”), and Western Digital Ireland, Ltd., our indirect wholly owned subsidiary (“WDI”). Pursuant to the Purchase Agreement, WDI agreed to acquire all of the issued and outstanding paid-up share

Table of Contents

capital of HGST from Hitachi. The planned acquisition is intended to result in a more efficient and innovative customer-focused storage company, with significant operating scale, strong global talent and the industry’s broadest product lineup backed by a rich technology portfolio. The aggregate purchase price of the planned acquisition is estimated to be approximately $4.3 billion, due at closing, and will be funded with existing cash, new debt, and 25 million newly issued shares of our common stock. The Purchase Agreement contains certain termination rights for both us and Hitachi, including the right to terminate the Purchase Agreement if the planned acquisition has not closed by March 7, 2012. If the planned acquisition has not closed by March 7, 2012 due to the failure to receive any required antitrust or competition authority’s consent, approval or clearance or any action by any certain governmental entities to prevent the planned acquisition for antitrust or competition reasons, we will, concurrently with such termination, be required to pay Hitachi a fee of $250 million in cash.
 
On March 7, 2011, in connection with the planned acquisition of HGST, WD, Western Digital Technologies, Inc. (“WDTI”), our wholly-owned subsidiary, and WDI entered into a commitment letter with Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated regarding a new credit facility for an amount of $2.5 billion, consisting of a $500 million revolving credit facility and $2.0 billion in term loans, to be entered into in connection with the closing of the planned acquisition (the “Senior Facility”). Since entering into the commitment letter, Bank of America N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated led the effort to syndicate the Senior Facility for an amount of up to $3.0 billion, consisting of a $500 million revolving credit facility and up to $2.5 billion in term loans. As a result of such effort, WD, WDTI and WDI have fully negotiated definitive loan documents for the Senior Facility with the syndicate members and, subject to customary closing conditions including completion of the acquisition in accordance with the terms, WD, WDTI and WDI fully expect all of these syndicate members to be part of the final lender group. We are required to pay a commitment fee at the rate of 0.35%, per annum, of the aggregate unfunded amount committed to be borrowed under the Senior Facility.
 
The planned acquisition of HGST is subject to several closing conditions, including the receipt of antitrust approvals or the expiration of applicable waiting periods in certain jurisdictions. We have received requests for additional information and are engaged in more in-depth reviews of the pending acquisition initiated by regulatory authorities in the United States, the European Union, the People’s Republic of China, Japan and Korea. We are cooperating fully with each of the regulatory authorities reviewing the proposed transaction. Subject to obtaining the required regulatory approvals or expiration of applicable waiting periods, we expect the transaction to close in our second quarter of fiscal 2012.
 
Results of Operations
 
Fiscal 2011 Overview
 
In 2011, our net revenue decreased by 3% to $9.5 billion on hard drive shipments of 207 million units as compared to $9.8 billion and 194 million units in 2010. In 2011, 64% of our hard drive net revenue was derived from compute markets, including notebook and desktop computers, as compared to 67% in 2010. Hard drive ASP decreased to $45 in 2011 from $50 in 2010. Gross margin percentage decreased to 18.8% in 2011 from 24.4% in 2010. In 2011, operating income decreased from $1.5 billion to $781 million, which included a $25 million accrual for litigation contingencies and $17 million of expenses related to the planned acquisition of HGST. As a percentage of net revenue, operating income was 8.2% in 2011 compared to 15.5% in 2010. Net income in 2011 was $726 million, or $3.09 per diluted share, compared to $1.4 billion, or $5.93 per diluted share, in 2010.
 
For the September quarter, we expect our revenue to increase slightly from the June quarter primarily as a result of seasonality.

Fiscal Year 2011 Compared to Fiscal Year 2010
 
Net Revenue.  Net revenue was $9.5 billion for 2011, a decrease of 3% from 2010. Total hard drive shipments increased to 207 million units as compared to 194 million units for the prior year. The decrease in net revenue resulted primarily from a $5 decrease in ASP from $50 to $45, partially offset by the increase in unit shipments.

Table of Contents

Changes in revenue by geography and channel generally reflect normal fluctuations in market demand and competitive dynamics.
 
In accordance with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For 2011 and 2009, these programs represented 11% of gross revenues compared to 8% in 2010. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product.
 
Gross Margin.  Gross margin for 2011 was $1.8 billion, a decrease of $610 million, or 25% from the prior year. Gross margin as a percentage of net revenue decreased to 18.8% in 2011 from 24.4% in 2010. This decrease was primarily due to an aggressive pricing environment, resulting in a lower ASP.
 
Operating Expenses.  Total research and development (“R&D”) expense and selling, general and administrative (“SG&A”) expense increased to 10.6% of net revenue in 2011 compared to 8.9% in 2010. R&D expense was $703 million in 2011, an increase of $92 million, or 15% over the prior year. As a percentage of net revenue, R&D expense increased to 7.4% in 2011 compared to 6.2% in 2010. This increase in R&D expense was primarily due to the continued investment in product development to support new programs. SG&A expense was $307 million in 2011, an increase of $42 million, or 16%, as compared to 2010. SG&A expense as a percentage of net revenue increased to 3.2% in 2011 compared to 2.7% in 2010. This increase in SG&A expense was primarily due to the expansion of sales and marketing to support new products and growing markets as well as $17 million of expenses related to the planned acquisition of HGST.
 
Other Income (Expense).  Other expense, net was $1 million in 2011 compared to $5 million in 2010. This decrease was primarily due to an increase in interest income of $5 million due to higher average daily invested cash balances and a $1 million decrease in our term loan interest expense due to a lower principal balance, partially offset by acquisition-related debt commitment fees of $2 million.
 
Income Tax Provision.  Income tax expense was $54 million in 2011 as compared to $138 million in 2010. Tax expense as a percentage of income before taxes was 7% in 2011 compared to 9% for 2010. Income tax expense for 2011 reflects the extension of the R&D tax credit that was signed into law in December 2010. The differences between the effective tax rate and the U.S. Federal statutory rate are primarily due to tax holidays in Malaysia, Singapore and Thailand that expire at various dates through 2023 and the current year generation of income tax credits.
 
We recognized a net increase of $15 million in our liability for unrecognized tax benefits during 2011. As of July 1, 2011, we had a recorded liability for unrecognized tax benefits of approximately $245 million. Interest and penalties recognized on such amounts were not material.
 
The United States Internal Revenue Service (“IRS”) is currently examining our fiscal years 2006 and 2007 and calendar years 2005 and 2006 for Komag, Incorporated (“Komag”), which was acquired by us on September 5, 2007. The IRS has completed its field work and proposed certain adjustments. Certain issues have been agreed upon by us and the IRS and certain issues remain unresolved. We have received Revenue Agent Reports (“RARs”) for the agreed issues. We have also received RARs from the IRS for the unresolved issues that seek adjustments to our income before income taxes of approximately $970 million and $380 million for Komag. The issues in dispute relate primarily to transfer pricing and certain other intercompany transactions. We disagree with the proposed adjustments. In May 2011, we filed a protest with the IRS Appeals Office regarding the proposed adjustments for Western Digital. We are continuing discussions with the IRS to resolve the Komag issues.
 
We believe that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in our tax audits are resolved in a manner not consistent with management’s expectations, we could be required to adjust our provision for income taxes in the period such resolution occurs. As of July 1, 2011, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months.
 
Fiscal Year 2010 Compared to Fiscal Year 2009
 
Net Revenue.  Net revenue was $9.8 billion for 2010, an increase of 32% from 2009. Total hard drive shipments increased to 194 million units as compared to 146 million units for the prior year. The increase in net revenue resulted


35


Table of Contents

primarily from an increase in unit shipments due to the strong demand for hard drives, particularly in the mobile PC market. We shipped 80 million mobile drives in 2010 as compared to 55 million units in 2009. The increase in mobile unit shipments was driven by continued strength in notebook and netbook PC demand, coupled with increased customer preference for our product offerings.
 
Changes in revenue by geography generally reflect normal fluctuations in market demand and competitive dynamics, as well as demand strength in Asia, which continues to be driven by the concentration of global manufacturing in that region. Changes in revenue by channel are a result of normal fluctuations in market demand and competitive dynamics.
 
In accordance with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For 2010, these programs represented 8% of gross revenues compared to 11% in 2009 and 10% in 2008, respectively. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product.
 
Gross Margin.  Gross margin for 2010 was $2.4 billion, an increase of $1.1 billion, or 80% over the prior year. Gross margin as a percentage of net revenue increased to 24.4% in 2010 from 17.9% in 2009. This increase was primarily due to higher volume, lower costs, a favorable product mix and a moderate pricing environment.
 
Operating Expenses.  Total R&D expense and SG&A expense decreased to 8.9% of net revenue in 2010 compared to 9.5% in 2009. R&D expense was $611 million in 2010, an increase of $102 million, or 20% over the prior year. This increase in R&D expense was primarily due to a $68 million increase relating to product development to support new programs and a $34 million increase in variable incentive compensation. As a percentage of net revenue, R&D expense decreased to 6.2% in 2010 compared to 6.8% in 2009 primarily due to an increase in net revenue in 2010 compared to 2009. SG&A expense was $265 million in 2010, an increase of $64 million, or 32%, as compared to 2009. This increase in SG&A expense was primarily due to $27 million of expense related to litigation settlements, a $19 million increase in variable incentive compensation and an $18 million increase in the expansion of our sales and marketing presence into new regions. SG&A expense as a percentage of net revenue remained consistent at 2.7% in 2010 and 2009.
 
During 2009, we recorded a $14 million in-process research and development charge related to the acquisition of SiliconSystems. This charge relates to projects that were not ready for commercial production and had no alternative future use and, therefore, the fair value of the development effort did not qualify for capitalization and was immediately expensed. During 2009, we also recorded $112 million in restructuring charges and an $18 million gain on the sale of our substrate manufacturing facility, and related assets, in Sarawak, Malaysia.
 
Other Income (Expense).  Other expense, net was $5 million in 2010 compared to $18 million in 2009. This decrease was primarily due to no impairment charges related to our auction-rate securities in 2010, compared to $10 million in other-than-temporary losses in 2009, as well as decreases in the variable interest rate on a lower amount of debt.
 
Income Tax Provision.  Income tax expense was $138 million in 2010 as compared to $31 million in 2009. Tax expense as a percentage of income before taxes was 9% in 2010 compared to 6% for 2009. In 2009, income tax expense included a provision of $42 million offset by $6 million in tax benefits related to the extension of the U.S. Federal research and development tax credit enacted into law in October 2008, and a favorable adjustment of $5 million to previously recorded tax accruals and credits. Differences between the effective tax rate and the U.S. Federal statutory rate were primarily due to tax holidays in Malaysia and Thailand that expire at various dates through 2022 and the current year generation of income tax credits.
 
We recognized a net $94 million increase in the liability for unrecognized tax benefits during 2010. As of July 2, 2010, we had approximately $230 million of unrecognized tax benefits which, if recognized, would decrease the effective tax rate in subsequent years.

Liquidity and Capital Resources
 
We ended 2011 with total cash and cash equivalents of $3.5 billion, an increase of $756 million from July 2, 2010. The following table summarizes our statements of cash flows for the three years ended July 1, 2011 (in millions):

Net increase in cash and cash equivalents
  $ 756     $ 940     $ 690  
                         
 
Our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing return through the full investment of available funds. We believe our current cash, cash equivalents and cash generated from operations will be sufficient to meet our working capital and capital expenditure needs through the foreseeable future. Our ability to sustain our working capital position is subject to a number of risks that we discuss in Item 1A of this Annual Report on Form 10-K.
 
Operating Activities
 
Net cash provided by operating activities during 2011 was $1.7 billion as compared to $1.9 billion for 2010 and $1.3 billion for 2009. Cash flow from operating activities consists of net income, adjusted for non-cash charges, plus or minus working capital changes. This represents our principal source of cash. Net cash provided by working capital changes was $238 million for 2011 as compared to net cash used to fund working capital of $37 million for 2010 and net cash provided by working capital changes of $198 million for 2009.
 
Our working capital requirements primarily depend on the effective management of our cash conversion cycle, which measures how quickly we can convert our products into cash through sales. The average quarterly cash conversion cycles for the three years ended 2011 were as follows:
 
                         
    Years Ended  
    July 1,
    July 2,
    July 3,
 
    2011     2010     2009  
 
Days sales outstanding
    47       46       47  
Days in inventory
    27       23       26  
Days payables outstanding

Cash conversion cycle
    (1 )     (3 )     6  
                         
 
For 2011, our average days sales outstanding (“DSOs”) increased by one day, days in inventory (“DIOs”) increased by four days, and days payables outstanding (“DPOs”) increased by three days. Changes in average DSOs and DIOs are generally related to linearity of shipments and the timing of inventory builds, respectively. Changes in DPOs are generally related to production volume and the timing of purchases during the period. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make the payment modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations.
 
Investing Activities
 
Net cash used in investing activities for 2011 was $793 million as compared to $986 million for 2010 and $551 million for 2009. During 2011, cash used in investing activities consisted of capital expenditures of $778 million and $15 million for equipment related to the acquisition of a semiconductor wafer fabrication facility. During 2010, cash used in investing activities consisted primarily of $737 million for capital expenditures, $233 million used for the acquisition of the magnetic media sputtering operations of Hoya and $20 million used for the acquisition of the land and

building associated with the acquisition of a semiconductor wafer fabrication facility, offset by $3 million of sales related to our auction-rate securities. During 2009, cash used in investing activities consisted primarily of $519 million for capital expenditures and $63 million for the acquisition of SiliconSystems, net of cash acquired, partially offset by $29 million in proceeds from the sale of property and equipment. Capital expenditures in 2011 primarily consisted of the expansion of our head wafer fabrication facilities, continued investment in advanced head technologies and increased capacity for our broadening and growing product portfolio.
 
For fiscal 2012, we expect capital expenditures will be at the upper end of our business model range of between 7 and 8 percent of revenue as we continue the conversion of our head wafer fabrication facilities to utilize 8-inch wafers from 6-inch wafers. We expect depreciation and amortization to be approximately $650 million for fiscal 2012.
 
Our cash equivalents are invested in highly liquid money market funds that are invested in U.S. Treasury securities, U.S. Treasury bills and U.S. Government agency securities. We also have $15 million of auction-rate securities, which are classified as available-for-sale securities.
 
Financing Activities
 
Net cash used in financing activities for 2011 was $106 million as compared to $16 million for 2010 and $64 million for 2009. Net cash used in financing activities for 2011 consisted of $106 million used to repay long-term debt and $50 million used to repurchase shares of our common stock, offset by a net $50 million related to employee stock plans. Net cash used in financing activities for 2010 consisted of $82 million used to repay long-term debt, partially offset by a net $66 million provided by employee stock plans. Net cash used in financing activities for 2009 consisted of $36 million used to repurchase shares of our common stock, $27 million used to repay long-term debt and a net $1 million used by employee stock plans.
 
Off-Balance Sheet Arrangements
 
Other than facility lease commitments incurred in the normal course of business and certain indemnification provisions (see “Contractual Obligations and Commitments” below), we do not have any off-balance sheet financing arrangements or liabilities, guarantee contracts, retained or contingent interests in transferred assets, or any obligation arising out of a material variable interest in an unconsolidated entity. We do not have any majority-owned subsidiaries that are not included in the consolidated financial statements. Additionally, we do not have an interest in, or relationships with, any special-purpose entities.
 
Contractual Obligations and Commitments
 
The following is a summary of our significant contractual cash obligations and commercial commitments as of July 1, 2011 (in millions):

Long-Term Debt
 
In February 2008, WDTI, a wholly-owned subsidiary of the Company, entered into a five-year credit agreement that provided for a $500 million term loan facility. As of July 1, 2011, the remaining balance of the term loan facility was $294 million, which requires principal payments totaling $144 million in 2012 and $150 million in 2013. See Part II, Item 8, Note 3 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

On March 7, 2011, in connection with the planned acquisition of HGST, WD, WDTI and WDI entered into a commitment letter for the Senior Facility. Since entering into the commitment letter, Bank of America N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated led the effort to syndicate the Senior Facility for an amount of up to $3.0 billion, consisting of a $500 million revolving credit facility and up to $2.5 billion in term loans. As a result of such effort, WD, WDTI and WDI have fully negotiated definitive loan documents for the Senior Facility with the syndicate members and, subject to customary closing conditions, including completion of the acquisition in accordance with the terms, WD, WDTI and WDI fully expect all of these syndicate members to be part of the final lender group. We are required to pay a commitment fee at the rate of 0.35%, per annum, of the aggregate unfunded amount committed to be borrowed under the Senior Facility.
 
Purchase Orders
 
In the normal course of business, we enter into purchase orders with suppliers for the purchase of hard drive components used to manufacture our products. These purchase orders generally cover forecasted component supplies needed for production during the next quarter, are recorded as a liability upon receipt of the components, and generally may be changed or canceled at any time prior to shipment of the components. We also enter into purchase orders with suppliers for capital equipment that are recorded as a liability upon receipt of the equipment. Our ability to change or cancel a capital equipment purchase order without penalty depends on the nature of the equipment being ordered. In some cases, we may be obligated to pay for certain costs related to changes to, or cancellation of, a purchase order, such as costs incurred for raw materials or work in process of components or capital equipment.
 
We have entered into long-term purchase agreements with various component suppliers, which contain minimum quantity requirements. However, the dollar amount of the purchases may depend on the specific products ordered, achievement of pre-defined quantity or quality specifications or future price negotiations. The estimated related minimum purchase requirements are included in “Purchase obligations” in the table above. We have also entered into long-term purchase agreements with various component suppliers that carry fixed volumes and pricing which obligate us to make certain future purchases, contingent on certain conditions of performance, quality and technology of the vendor’s components. These arrangements are included under “Purchase obligations” in the table above.
 
We enter into, from time to time, other long-term purchase agreements for components with certain vendors. Generally, future purchases under these agreements are not fixed and determinable as they depend on our overall unit volume requirements and are contingent upon the prices, technology and quality of the supplier’s products remaining competitive. These arrangements are not included under “Purchase obligations” in the table above. Please see Item 1A of this Annual Report on Form 10-K for a discussion of risks related to these commitments.
 
Foreign Exchange Contracts
 
We purchase short-term, foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, revenue, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. See Part II, Item 7A, under the heading “Disclosure About Foreign Currency Risk,” for a description of our current foreign exchange contract commitments and Part II, Item 8, Notes 1 and 11 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.
 
Indemnifications
 
In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of such agreements, products or services to be provided by us, or from intellectual property infringement claims made by third parties. In addition, we have entered into indemnification agreements with our directors and certain of our officers that will require us, among other things, to indemnify them against certain liabilities that may arise by reason of their status or service as directors or officers. We maintain director and officer insurance, which may cover certain liabilities arising from our obligation to indemnify our directors and officers in certain circumstances.
 
It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of prior indemnification claims and the unique facts and circumstances involved in each particular


39


Table of Contents

agreement. Such indemnification agreements may not be subject to maximum loss clauses. Historically, we have not incurred material costs as a result of obligations under these agreements.
 
Unrecognized Tax Benefits
 
As of July 1, 2011, the cash portion of our total recorded liability for unrecognized tax benefits was $147 million. We estimate the timing of the future payments of these liabilities to be within the next one to five years. See Part II, Item 8, Note 9 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for information regarding our total tax liability for unrecognized tax benefits.
 
Stock Repurchase Program
 
Our Board of Directors previously authorized us to repurchase $750 million of our common stock in open market transactions under a stock repurchase program through March 31, 2013. Since the inception of this program in 2005, through July 1, 2011, we have repurchased 20 million shares of our common stock for a total cost of $334 million. We repurchased 1.8 million shares for a total cost of $50 million during 2011. We may continue to repurchase our stock as we deem appropriate and market conditions allow. We expect stock repurchases to be funded principally by operating cash flows.
 
Planned Acquisition Termination Fee
 
If the planned acquisition of HGST has not closed by March 7, 2012 due to the failure to receive any required antitrust or competition authority’s consent, approval or clearance or any action by any certain governmental entities to prevent the planned acquisition for antitrust or competition reasons, we will, concurrently with such termination, be required to pay Hitachi a fee of $250 million in cash.
 
Critical Accounting Policies and Estimates
 
We have prepared the accompanying consolidated financial statements in accordance with U.S. GAAP. The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues, expenses, assets, liabilities and shareholders’ equity. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate. We believe the following are our most critical accounting policies that affect significant areas and involve judgment and estimates made by us. If these estimates differ significantly from actual results, the impact to the consolidated financial statements may be material.
 
Revenue and Accounts Receivable
 
In accordance with standard industry practice, we provide distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions, and we provide resellers and OEMs with other sales incentive programs. At the time we recognize revenue to resellers and OEMs, we record a reduction of revenue for estimated price protection until the resellers sell such inventory to their customers and we also record a reduction of revenue for the other programs in effect. We base these adjustments on several factors including anticipated price decreases during the reseller holding period, resellers’ sell-through and inventory levels, estimated amounts to be reimbursed to qualifying customers, historical pricing information and customer claim processing. If customer demand for hard drives or market conditions differs from our expectations, our operating results could be materially affected. We also have programs under which we reimburse qualified distributors and retailers for certain marketing expenditures, which are recorded as a reduction of revenue. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product. Since 2009, total sales incentive and marketing programs have ranged from 7% to 12% of gross revenues per quarter. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue from the current range. Adjustments to revenues due to changes in accruals for these programs related to revenues reported in prior periods have averaged 0.3% of quarterly gross revenue since the first quarter of fiscal 2009. Customer sales incentive and marketing programs are recorded as a reduction of revenue.
 
We record an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency, disputes or other collection issues. In addition, we routinely analyze the different receivable aging


40


Table of Contents

categories and establish reserves based on a combination of past due receivables and expected future losses based primarily on our historical levels of bad debt losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if our overall loss history changes significantly, an adjustment in our allowance for doubtful accounts would be required, which could materially affect operating results.
 
We establish provisions against revenue and cost of revenue for sales returns in the same period that the related revenue is recognized. We base these provisions on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.
 
Warranty
 
We record an accrual for estimated warranty costs when revenue is recognized. We generally warrant our products for a period of one to five years. Our warranty provision considers estimated product failure rates and trends, estimated repair or replacement costs and estimated costs for customer compensatory claims related to product quality issues, if any. We use a statistical warranty tracking model to help prepare our estimates and assist us in exercising judgment in determining the underlying estimates. Our statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Our judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base our warranty estimates. We review our warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross margin and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from our estimates, our future results of operations could be materially affected. For a summary of historical changes in estimates related to pre-existing warranty provisions, refer to Part II, Item 8, Note 4 in the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K.
 
Inventory
 
We value inventories at the lower of cost (first-in, first-out and weighted average methods) or net realizable value. We use the first-in, first-out (“FIFO”) method to value the cost of the majority of our inventories, while we use the weighted-average method to value precious metal inventories. Weighted-average cost is calculated based upon the cost of precious metals at the time they are received by us. We have determined that it is not practicable to assign specific costs to individual units of precious metals and, as such, we relieve our precious metals inventory based on the weighted-average cost of the inventory at the time the inventory is used in production. The weighted average method of valuing precious metals does not materially differ from a FIFO method. We record inventory write-downs for the valuation of inventory at the lower of cost or net realizable value by analyzing market conditions and estimates of future sales prices as compared to inventory costs and inventory balances.
 
We evaluate inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information, and reduce inventory balances to net realizable value for excess and obsolete inventory based on this analysis. Unanticipated changes in technology or customer demand could result in a decrease in demand for one or more of our products, which may require a write down of inventory that could materially affect operating results.
 
Litigation and Other Contingencies
 
When we become aware of a claim or potential claim, we assess the likelihood of any loss or exposure. We disclose information regarding each material claim where the likelihood of a loss contingency is probable or reasonably possible. If a loss contingency is probable and the amount of the loss can be reasonably estimated, we record an accrual for the loss. In such cases, there may be an exposure to potential loss in excess of the amount accrued. Where a loss is not probable but is reasonably possible, and where a loss in excess of the amount accrued is reasonably possible, we disclose an estimate of the amount of the loss or range of possible losses for the claim if a reasonable estimate can be made, unless the amount of such reasonably possible losses is not material to our financial position, results of operations or cash flows. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual


41


Table of Contents

outcome of such matters could differ materially from management’s estimates. Refer to Part II, Item 8, Note 5 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.
 
Income Taxes
 
We account for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities and expected benefits of utilizing net operating loss and tax credit carryforwards. We record a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each period we evaluate the need for a valuation allowance for our deferred tax assets and we adjust the valuation allowance so that we record net deferred tax assets only to the extent that we conclude it is more likely than not that these deferred tax assets will be realized.
 
We recognize liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in our provision for income taxes. The actual liability for unrealized tax benefits in any such contingency may be materially different from our estimates, which could result in the need to record additional liabilities for unrecognized tax benefits or potentially adjust previously-recorded liabilities for unrealized tax benefits and materially affect our operating results.
 
Stock-based Compensation
 
We account for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options granted are estimated using a binomial model, and the fair values of all Employee Stock Purchase Plan (“ESPP”) purchase rights are estimated using the Black-Scholes-Merton option-pricing model. Both the binomial and the Black-Scholes-Merton models require the input of highly subjective assumptions. We are required to use judgment in estimating the amount of stock-based awards that are expected to be forfeited. If actual forfeitures differ significantly from the original estimate, stock-based compensation expense and our results of operations could be materially affected.
 
Recent Accounting Pronouncements
 
For a description of recently issued and adopted accounting pronouncements, including the respective dates of adoption and expected effects on our results of operations and financial condition, refer to Part II, Item 8, Note 1 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K, which is incorporated by reference in response to this item.
 
Item 7A.   Quantitative and Qualitative Disclosures About Market Risk
 
Disclosure About Foreign Currency Risk
 
Although the majority of our transactions are in U.S. dollars, some transactions are based in various foreign currencies. We purchase short-term, foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, revenue, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedge transactions is to minimize the impact of foreign currency fluctuations on our results of operations. The contract maturity dates do not exceed 12 months. We do not purchase foreign exchange contracts for trading purposes. Currently, we focus on hedging our foreign currency risk related to the Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling. Thai Baht contracts are designated as either cash flow or fair value hedges. Malaysian Ringgit contracts are designated as cash flow hedges. Euro and British Pound Sterling contracts are designated as fair value hedges. See Part II, Item 8, Notes 1 and 11 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.

Disclosure About Other Market Risks
 
Variable Interest Rate Risk
 
Borrowings under the term loan facility bear interest at a rate equal to, at the option of WDTI, either (a) a LIBOR rate determined by reference to the cost of funds for Eurodollar deposits for the interest period relevant to such borrowing, adjusted for certain additional costs (the “Eurocurrency Rate”) or (b) a base rate determined by reference to the higher of (i) the federal funds rate plus 0.50% and (ii) the prime rate as announced by JPMorgan Chase Bank, N.A. (the “Base Rate”); in each case plus an applicable margin. The applicable margin for borrowings under the term loan facility ranges from 1.25% to 1.50% with respect to borrowings at the Eurocurrency Rate and 0.0% to 0.125% with respect to borrowings at the Base Rate. The applicable margins for borrowings under the term loan facility are determined based upon a leverage ratio of the Company and its subsidiaries calculated on a consolidated basis. If the federal funds rate, prime rate or LIBOR rate increase, our interest payments could also increase. A one percent increase in the variable rate of interest on the term loan facility would increase interest expense by approximately $3 million annually.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
The Board of Directors and Shareholders
Western Digital Corporation:
 
We have audited the accompanying consolidated balance sheets of Western Digital Corporation and subsidiaries as of July 1, 2011 and July 2, 2010, and the related consolidated statements of income, shareholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended July 1, 2011. In connection with our audits of the consolidated financial statements, we have also audited the related financial statement schedule. These consolidated financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements and financial statement schedule based on our audits.
 
We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
 
The Board of Directors and Shareholders
Western Digital Corporation:
 
We have audited Western Digital Corporation’s internal control over financial reporting as of July 1, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting appearing under Item 9A. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.
 
We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.
 
A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.
 
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
 
In our opinion, Western Digital Corporation maintained, in all material respects, effective internal control over financial reporting as of July 1, 2011, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Western Digital Corporation and subsidiaries as of July 1, 2011 and July 2, 2010, the related consolidated statements of income, shareholders’ equity and comprehensive income, and cash flows for each of the years in the three-year period ended July 1, 2011, and the related financial statement schedule, and our report dated August 11, 2011, expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
Note 1.  Organization and Summary of Significant Accounting Policies
 
Western Digital Corporation (the “Company” or “Western Digital” or “WD”) is a global provider of solutions for the collection, storage, management, protection and use of digital content, including audio and video. The Company’s principal products are hard drives, which are devices that use one or more rotating magnetic disks (“magnetic media”) to store and allow fast access to data. Hard drives are currently the primary storage medium for digital content. The Company’s hard drives are used in desktop and notebook computers, corporate and cloud computing data centers, home entertainment equipment and stand-alone consumer storage devices. In addition to hard drives, the Company’s other products include solid-state drives and home entertainment and networking products.
 
The Company has prepared its consolidated financial statements in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) and has adopted accounting policies and practices which are generally accepted in the industry in which it operates. The Company’s significant accounting policies are summarized below.
 
Fiscal Year
 
The Company has a 52 or 53-week fiscal year. The 2011 fiscal year which ended on July 1, 2011 consisted of 52 weeks. The 2010 and 2009 fiscal years, which ended on July 2, 2010 and July 3, 2009, respectively, consisted of 52 and 53 weeks each, respectively.
 
Basis of Presentation
 
The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The accounts of foreign subsidiaries have been remeasured using the U.S. dollar as the functional currency. As such, gains or losses resulting from remeasurement of these accounts from local currencies into U.S. dollars are reflected in the results of operations. These gains and losses were immaterial to the consolidated financial statements.
 
On June 30, 2010, the Company acquired the magnetic media sputtering operations of Hoya Corporation and Hoya Magnetics Singapore Pte. Ltd (together, “Hoya”). On March 27, 2009, the Company acquired SiliconSystems, Inc. (“SiliconSystems”). The acquisitions are further described in Note 14. The results of operations of Hoya and SiliconSystems since the dates of their acquisitions are included in the consolidated financial statements.
 
Cash and Cash Equivalents
 
The Company’s cash equivalents represent highly liquid investments in money market funds, which are invested in U.S. Treasury securities, U.S. Treasury bills and U.S. Government agency securities with original maturities when purchased of three months or less.
 
Investments
 
The Company’s investments consist of auction-rate securities, which are primarily backed by insurance products with original maturities greater than three months. The Company has classified these investments as available-for-sale securities and they are carried at fair value within other non-current assets in the consolidated balance sheets.
 
Fair Value of Financial Instruments
 
The carrying amounts of cash equivalents, accounts receivable, investments, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities or, in the case of investments, these are recorded using appropriate market information. The carrying amount of debt approximates fair value because of its variable interest rate.

WESTERN DIGITAL CORPORATION
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
Concentration of Credit Risk
 
The Company sells its products to computer manufacturers, resellers and retailers throughout the world. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. The Company maintains allowances for potential credit losses, and such losses have historically been within management’s expectations. At any given point in time, the total amount outstanding from any one of a number of its customers may be individually significant to the Company’s financial results. At July 1, 2011 and July 2, 2010, the Company had reserves for potential credit losses of $5 million and $6 million, respectively, and net accounts receivable of $1.2 billion and $1.3 billion, respectively.
 
The Company also has cash equivalent and investment policies that limit the amount of credit exposure to any one financial institution or investment instrument and requires that investments be made only with financial institutions or in investment instruments evaluated as highly credit-worthy.
 
Inventory
 
The Company values inventories at the lower of cost (first-in, first out and weighted average methods) or net realizable value. The first-in, first-out (“FIFO”) method is used to value the cost of the majority of the Company’s inventories, while the weighted-average method is used to value precious metal inventories. Weighted-average cost is calculated based upon the cost of precious metals at the time they are received by the Company. The Company has determined that it is not practicable to assign specific costs to individual units of precious metals and, as such, precious metals are relieved from inventory based on the weighted-average cost of the inventory at the time the inventory is used in production. The weighted average method of valuing precious metals does not materially differ from a FIFO method. As of July 1, 2011 and July 2, 2010, 85% and 82% of the inventory was valued using the FIFO method with the remainder valued using the weighted average method. Inventory write-downs are recorded for the valuation of inventory at the lower of cost or net realizable value by analyzing market conditions and estimates of future sales prices as compared to inventory costs and inventory balances.
 
The Company evaluates inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information, and reduces inventory balances to net realizable value for excess and obsolete inventory based on this analysis. Unanticipated changes in technology or customer demand could result in a decrease in demand for one or more of the Company’s products, which may require a write down of inventory that could materially affect operating results.
 
Property, Plant and Equipment
 
The cost of property, plant and equipment is depreciated over the estimated useful lives of the respective assets. The Company’s buildings are depreciated over periods ranging from fifteen to thirty years. The majority of the Company’s equipment is depreciated over periods of three to seven years. Depreciation is computed on a straight-line basis. Leasehold improvements are amortized over the lesser of the estimated useful lives of the assets or the related lease terms.
 
Goodwill and Other Long-Lived Assets
 
The total purchase price in a business combination is allocated to the fair value of assets acquired and liabilities assumed based on their fair values at the acquisition date, with amounts exceeding the fair values being recorded as goodwill. Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. The Company did not record any impairment of goodwill during 2011, 2010 or 2009.
 
Other intangible assets consist primarily of technology acquired in business combinations. Acquired intangibles are amortized on a straight-line basis over their respective estimated useful lives. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
The Company did not record any impairments to long-lived assets during 2011 or 2010. The Company recorded impairments to certain long-lived assets during 2009. See Note 13.
 
Revenue and Accounts Receivable
 
Revenue is recognized when the title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, delivery has occurred, or services have been rendered, the sales price is fixed or determinable and collectability is reasonably assured. The Company establishes provisions against revenue and cost of revenue for estimated sales returns in the same period that the related revenue is recognized based on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.
 
In accordance with standard industry practice, the Company provides distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions, and the Company provides resellers and OEMs with other sales incentive programs. At the time the Company recognizes revenue to resellers and OEMs, a reduction of revenue is recorded for estimated price protection until the resellers sell such inventory to their customers and the Company also records a reduction of revenue for the other programs in effect. The Company bases these adjustments on several factors including anticipated price decreases during the reseller holding period, reseller’s sell-through and inventory levels, estimated amounts to be reimbursed to qualifying customers, historical pricing information and customer claim processing. If customer demand for hard drives or market conditions differ from the Company’s expectations, the Company’s operating results could be materially affected. The Company also has programs under which it reimburses qualified distributors and retailers for certain marketing expenditures, which are recorded as a reduction of revenue. Sales incentive and marketing programs are recorded as a reduction of revenue.
 
The Company records an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency, disputes or other collection issues. In addition, the Company routinely analyzes the different receivable aging categories and establishes reserves based on a combination of past due receivables and expected future losses based primarily on its historical levels of bad debt losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if the Company’s overall loss history changes significantly, an adjustment in the Company’s allowance for doubtful accounts would be required, which could materially affect operating results.
 
The Company establishes provisions against revenue and cost of revenue for sales returns in the same period that the related revenue is recognized. These provisions are based on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.
 
Warranty
 
The Company records an accrual for estimated warranty costs when revenue is recognized. The Company generally warrants its products for a period of one to five years. The warranty provision considers estimated product failure rates and trends, estimated repair or replacement costs and estimated costs for customer compensatory claims related to product quality issues, if any. A statistical warranty tracking model is used to help prepare estimates and assist the Company in exercising judgment in determining the underlying estimates. The statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Management’s judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base warranty estimates. Management reviews the warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross margin and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If

actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from estimates, future results of operations could be materially affected.
 
Litigation and Other Contingencies
 
When the Company becomes aware of a claim or potential claim, the Company assesses the likelihood of any loss or exposure. The Company discloses information regarding each material claim where the likelihood of a loss contingency is probable or reasonably possible. If a loss contingency is probable and the amount of the loss can be reasonably estimated, the Company records an accrual for the loss. In such cases, there may be an exposure to potential loss in excess of the amount accrued. Where a loss is not probable but is reasonably possible and where a loss in excess of the amount accrued is reasonably possible, the Company discloses an estimate of the amount of the loss or range of possible losses for the claim if a reasonable estimate can be made, unless the amount of such reasonably possible losses is not material to the Company’s financial position, results of operations or cash flows. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. See Note 5.
 
Advertising Expense
 
Advertising costs are expensed as incurred. Selling, general and administrative expenses of the Company included advertising costs of $11 million, $7 million, and $5 million in 2011, 2010 and 2009, respectively.
 
Income Taxes
 
The Company accounts for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of assets and liabilities and expected benefits of utilizing net operating loss (“NOL”) and tax credit carryforwards. The Company records a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each period, the Company evaluates the need for a valuation allowance for its deferred tax assets and adjusts the valuation allowance so that the Company records net deferred tax assets only to the extent that it has concluded it is more likely than not that these deferred tax assets will be realized.
 
The Company recognizes liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions, as applicable, and are recorded in the provision for income taxes. The actual liability for unrealized tax benefits may be materially different from the Company’s estimates, which could result in the need to record additional liabilities for unrecognized tax benefits or potentially adjust previously-recorded liabilities for unrealized tax benefits, and may materially affect our operating results.
 
Income per Common Share
 
The Company computes basic income per common share using net income and the weighted average number of common shares outstanding during the period. Diluted income per common share is computed using net income and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include certain dilutive outstanding employee stock options, rights to purchase shares of common stock under the Company’s Employee Stock Purchase Plan (“ESPP”) and restricted stock unit awards.

* For purposes of computing diluted income per common share, certain potentially dilutive securities have been excluded from the calculation because their effect would have been anti-dilutive.
 
Stock-based Compensation
 
The Company accounts for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options granted are estimated using a binomial model, and the fair values of all ESPP purchase rights are estimated using the Black-Scholes-Merton option-pricing model. Both the binomial and the Black-Scholes-Merton option-pricing models require the input of highly subjective assumptions. The Company is required to use judgment in estimating the amount of stock-based awards that are expected to be forfeited. If actual forfeitures differ significantly from the original estimate, stock-based compensation expense and the results of operations could be materially affected.
 
Other Comprehensive Income (Loss)
 
Other comprehensive income (loss) refers to revenue, expenses, gains and losses that are recorded as an element of shareholders’ equity but are excluded from net income. The Company’s other comprehensive income (loss) is comprised of unrealized gains and losses on foreign exchange contracts.
 
Foreign Exchange Contracts
 
Although the majority of the Company’s transactions are in U.S. dollars, some transactions are based in various foreign currencies. The Company purchases short-term, foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, revenue, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Company’s results of operations. These contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Company does not purchase foreign exchange contracts for trading purposes. The Company had outstanding foreign exchange contracts with commercial banks for Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling with aggregate notional amounts of $1.5 billion and $1.1 billion at July 1, 2011 and July 2, 2010, respectively. Thai Baht contracts are designated as either cash flow or fair value hedges. Malaysian Ringgit contracts are designated as cash flow hedges. Euro and British Pound Sterling contracts are designated as fair value hedges.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
If the derivative is designated as a cash flow hedge, the effective portion of the change in fair value of the derivative is initially deferred in other comprehensive income (loss), net of tax. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts entered into for manufacturing-related activities are reported in cost of revenue. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. The Company determined the ineffectiveness associated with its cash flow hedges to be immaterial.
 
A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of operating expenses. All fair value hedges were determined to be effective. The fair value and the changes in fair value on these contracts were not material to the consolidated financial statements for all years presented. See Notes 10 and 11 for additional disclosures related to foreign exchange contracts.
 
Use of Estimates
 
Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates.
 
Recent Accounting Pronouncements
 
In September 2009, the FASB issued Accounting Standards Update (“ASU”) 2009-13, “Multiple-Deliverable Revenue Arrangements” (“ASU 2009-13”), and ASU 2009-14, “Certain Revenue Arrangements That Include Software Elements” (“ASU 2009-14”). ASU 2009-13 amends the revenue guidance under Subtopic 605-25, “Multiple Element Arrangements,” and addresses how to determine whether an arrangement involving multiple deliverables contains more than one unit of accounting and how arrangement consideration shall be measured and allocated to the separate units of accounting in the arrangement. ASU 2009-14 excludes tangible products containing software components and non-software components that function together to deliver the product’s essential functionality from the scope of Subtopic 985-605, “Revenue Recognition.” ASU 2009-13 and ASU 2009-14 are effective for fiscal periods beginning on or after June 15, 2010, which for the Company was the first quarter of fiscal 2011. The Company’s adoption of ASU 2009-13 and ASU 2009-14 had no impact on its consolidated financial statements.
 
In May 2011, the FASB issued ASU 2011-04, “Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (“ASU 2011-04”). ASU 2011-04 clarifies existing fair value measurement and disclosure requirements by amending certain fair value measurement principles and requiring additional disclosures regarding fair value measurements. ASU 2011-04 is effective for fiscal periods beginning after December 15, 2011, which for the Company is the third quarter of fiscal 2012. The Company is currently evaluating the impact that ASU 2011-04 will have on its consolidated financial statements.
 
In June 2011, the FASB issued ASU 2011-05 “Presentation of Comprehensive Income” (“ASU 2011-05”). ASU 2011-05 requires that all non-owner changes in shareholders’ equity be presented either in a single continuous statement of comprehensive income or in two separate but continuous statements. If presented in two separate statements, the first statement should present total net income and its components followed immediately by a second statement of total other comprehensive income, its components and the total comprehensive income. ASU 2011-05 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2011, which for the Company is the first quarter of fiscal 2013. The Company is currently evaluating the impact that ASU 2011-05 will have on its consolidated financial statements.

In February 2008, Western Digital Technologies, Inc. (“WDTI”), a wholly-owned subsidiary of the Company, entered into a five-year Credit Agreement that provided for a $500 million term loan facility. As of July 1, 2011, the term loan facility had a variable interest rate of 1.44% and a remaining balance of $294 million, which requires principal payments totaling $144 million in 2012 and $150 million in 2013. The term loan facility has a maturity date of February 11, 2013. The term loan facility requires WDTI to comply with a leverage ratio and an interest coverage ratio calculated on a consolidated basis for the Company and its subsidiaries. In addition, the term loan facility contains customary covenants, including covenants that limit or restrict WDTI’s and its subsidiaries’ ability to incur liens, incur indebtedness, make certain restricted payments, merge or consolidate and enter into certain speculative hedging arrangements. As of July 1, 2011, WDTI was in compliance with all covenants.

Note 5.   Legal Proceedings
 
When the Company becomes aware of a claim or potential claim, the Company assesses the likelihood of any loss or exposure. The Company discloses information regarding each material claim where the likelihood of a loss contingency is probable or reasonably possible. If a loss contingency is probable and the amount of the loss can be reasonably estimated, the Company records an accrual for the loss. In such cases, there may be an exposure to potential loss in excess of the amount accrued. Where a loss is not probable but is reasonably possible and where a loss in excess of the amount accrued is reasonably possible, the Company discloses an estimate of the amount of the loss or range of possible losses for the claim if a reasonable estimate can be made, unless the amount of such reasonably possible losses is not material to the Company’s financial position, results of operations or cash flows. For the matters described below, the Company has either recorded an accrual for losses that are probable and reasonably estimable or has determined that, while a loss is reasonably possible, a reasonable estimate of the amount of loss or range of possible losses with respect to the claim, including the amount of loss in excess of the amount accrued, cannot be made. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates.

Intellectual Property Litigation
 
On June 20, 2008, plaintiff Convolve, Inc. (“Convolve”) filed a complaint in the Eastern District of Texas against the Company and two other companies alleging infringement of U.S. Patent Nos. 6,314,473 and 4,916,635. The complaint sought unspecified monetary damages and injunctive relief. On October 10, 2008, Convolve amended its complaint to allege infringement of only the ‘473 patent. The ‘473 patent allegedly relates to interface technology to select between certain modes of a disk drive’s operations relating to speed and noise. A trial in the matter began on July 18, 2011 and concluded on July 26, 2011 with a verdict against the Company in an amount that is not material to the Company’s financial position, results of operations or cash flows. The Company is evaluating its post-trial and appellate options.
 
On July 15, 2009, plaintiffs Carl B. Collins and Farzin Davanloo filed a complaint in the Eastern District of Texas against the Company and ten other companies alleging infringement of U.S. Patent Nos. 5,411,797 and 5,478,650.

Employment Litigation
 
On March 20, 2009, plaintiff Ghazala H. Durrani, a former employee of the Company, filed a putative class action complaint in the Alameda County (California) Superior Court. The complaint alleged that certain of the Company’s engineers had been misclassified as exempt employees under California state law and were, therefore, due unspecified amounts for unpaid hourly overtime wages and other amounts, as well as penalties for allegedly missed meal and rest periods. By court order dated April 24, 2009, the case was transferred to the Orange County (California) Superior Court. On or about June 16, 2009, the Company was dismissed from the case without prejudice by stipulation, leaving WDTI as the sole remaining defendant. On or about June 4, 2009, WDTI filed its answer to the complaint, denying the substantive allegations thereof and raising several affirmative defenses. The parties participated in a mediation of the case on June 3, 2010, which led to a proposed settlement of the case. The proposed settlement, which was ultimately approved by the court, resolved the case on a class-wide basis for an immaterial amount that was accrued by the Company in the fourth quarter of fiscal 2010. The court granted final approval of the settlement and entered judgment on February 7, 2011. A final accounting hearing took place on July 11, 2011, at which the court confirmed that the settlement amount was fully paid in accordance with the settlement agreement.
 
On February 26, 2010, and as thereafter amended on August 23, 2010 and December 22, 2010, plaintiff Tariq Sadaat, a former employee of the Company, filed a putative class action complaint in the Orange County (California) Superior Court against the Company, WDTI, Kelly Services, Inc., a Delaware corporation (“Kelly Services”), and certain other unnamed individuals. Plaintiff sought to represent certain hourly employees who were assigned to work at certain of the Company’s facilities by Kelly Services, a temporary staffing agency. In this regard, the complaint alleged that the hourly employees were due unspecified sums for unpaid overtime wages and other amounts, as well as penalties for allegedly missed meal and rest periods. The complaint sought unspecified damages including lost wages, penalties under the California Labor Code and other statutes, compensatory and punitive damages, declaratory relief, injunctive relief, interest, attorneys’ fees and costs. The Company’s response to the complaint was filed and served in January 2011. The parties participated in a mediation of the case, which led to a proposed settlement of Sadaat’s individual claims for an immaterial amount. The Court approved the proposed settlement on July 26, 2011, and dismissed the complaint in its entirety, with prejudice as to Sadaat’s individual claims and without prejudice as to the alleged class claims.
 
Other Matters
 
In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties and is therefore not predictable with assurance, management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability or financial impact to the Company from these other matters could differ materially from those projected.

Note 7.  Western Digital Corporation 401(k) Plan
 
The Company has adopted the Western Digital Corporation 401(k) Plan (the “Plan”). The Plan covers substantially all domestic employees, subject to certain eligibility requirements. The Company makes a basic matching contribution on behalf of each participating eligible employee equal to fifty percent (50%) of the eligible participant’s pre-tax contributions for the contribution cycle not to exceed 5% of the eligible participant’s compensation; provided, however, that each eligible participant shall receive a minimum annual basic matching contribution equal to fifty percent (50%) of the first $4,000 of pre-tax contributions for any calendar year. Company contributions vest over a 5-year period of employment. For 2011, 2010 and 2009, the Company made Plan contributions of $9 million, $9 million, and $7 million, respectively.
 
Note 8.  Shareholders’ Equity
 
Stock Incentive Plans
 
The Company maintains four stock-based incentive plans (collectively referred to as the “Stock Plans”): the amended and restated 2004 Performance Incentive Plan, the Employee Stock Option Plan, the Broad-Based Stock Incentive Plan and the Stock Option Plan for Non-Employee Directors. No new awards may be granted under the Employee Stock Option Plan, the Broad-Based Stock Incentive Plan or the Stock Option Plan for Non-Employee Directors (collectively referred to as the “Prior Stock Plans”). As of July 1, 2011, options to purchase 1.2 million shares of the Company’s common stock remained outstanding and exercisable under the Prior Stock Plans. Other than for such options, no restricted stock or other awards were outstanding under the Prior Stock Plans as of July 1, 2011. Options granted under the Prior Stock Plans expire either five or ten years from the date of grant.

The types of awards that may be granted under the 2004 Performance Incentive Plan include stock options, stock appreciation rights, restricted stock units (“RSUs”), stock bonuses and other forms of awards granted or denominated in the Company’s common stock or units of the Company’s common stock, as well as cash bonus awards. Persons eligible to receive awards under the 2004 Performance Incentive Plan include officers or employees of the Company or any of its subsidiaries, directors of the Company and certain consultants and advisors to the Company or any of its subsidiaries. The vesting of awards under the Performance Incentive Plan is determined at the date of grant. Each award expires on a date determined at the date of grant; however, the maximum term of options and stock appreciation rights under the 2004 Performance Incentive Plan is ten years after the grant date of the award. RSUs granted under the 2004 Performance Incentive Plan typically vest over periods ranging from one to five years from the date of grant.
 
As of July 1, 2011, the maximum number of shares of the Company’s common stock that was authorized for award grants under the 2004 Performance Incentive Plan was 37.2 million shares. Any shares subject to awards under the Prior Stock Plans that are canceled, forfeited or otherwise terminate without having vested or been exercised, as applicable, will become available for other award grants under the 2004 Performance Incentive Plan. Shares issued in respect of stock options and stock appreciation rights granted under the 2004 Performance Incentive Plan count against the plan’s share limit on a one-for-one basis, whereas shares issued in respect of any other type of award granted under the plan count against the plan’s share limit as 1.35 shares for every one share actually issued in connection with such award. The 2004 Performance Incentive Plan will terminate on September 20, 2014 unless terminated earlier by the Company’s Board of Directors.
 
Employee Stock Purchase Plan
 
The Company maintains an ESPP. Under the ESPP, eligible employees may authorize payroll deductions of up to 10% of their eligible compensation during prescribed offering periods to purchase shares of the Company’s common stock at 95% of the fair market value of common stock on either the first day of that offering period or on the applicable exercise date, whichever is less. A participant may participate in only one offering period at a time, and a new offering period generally begins each June 1st and December 1st. Each offering period is generally 24 months and consists of four exercise dates (each, generally six months following the start of the offering period or the preceding exercise date, as the case may be). If the fair market value of the Company’s common stock is less on a given exercise date than on the date of grant, employee participation in that offering period ends and participants are automatically re-enrolled in the next new offering period.
 
Stock-based Compensation Expense
 
The Company recognized in expense $37 million, $37 million and $24 million for stock-based compensation related to the vesting of options granted by the Company under the Stock Plans and the ESPP in 2011, 2010 and 2009, respectively. As of July 1, 2011, total compensation cost related to unvested stock options granted under the Stock Plans and ESPP rights issued to employees but not yet recognized was $60 million and will be amortized on a straight-line basis over a weighted average service period of approximately 2.2 years.
 
The Company recognized in expense $32 million, $23 million and $23 million related to restricted stock and restricted stock unit awards granted under the Stock Plans that vested during 2011, 2010 and 2009, respectively. As of July 1, 2011, the aggregate unamortized fair value of all unvested restricted stock unit awards granted under the Stock Plans was $41 million, which will be recognized on a straight-line basis over a weighted average vesting period of approximately 1.3 years.

If an option has an exercise price that is less than the quoted price of the Company’s common stock at the particular time, the aggregate intrinsic value of that option at that time is calculated based on the difference between the exercise price of the options and the quoted price of the Company’s common stock at that time. As of July 1, 2011, the Company had options outstanding to purchase an aggregate of 10.1 million shares with an exercise price below the quoted price of the Company’s stock on that date resulting in an aggregate intrinsic value of $145 million at that date. During 2011, 2010 and 2009, the aggregate intrinsic value of options exercised under the Stock Plans was $25 million, $72 million and $8 million, respectively, determined as of the date of exercise.

multiple at which employees are likely to exercise stock options and the expected employee termination rate. The Company uses historical data to estimate option exercise, employee termination, and expected stock price volatility within the binomial model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of stock options granted during the three years ended July 1, 2011 was estimated using the following weighted average assumptions:
 
             
    2011   2010   2009

Fair Value Disclosure — Black-Scholes-Merton Model
 
The fair value of ESPP purchase rights issued is estimated at the date of grant of the purchase rights using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model was developed for use in estimating the fair value of traded options that have no vesting restrictions and are fully transferable. The Black-Scholes-Merton option-pricing model requires the input of highly subjective assumptions such as the expected stock price volatility and the expected period until options are exercised. Purchase rights under the current ESPP provisions are granted on either June 1 or December 1 of each year.
 
The fair values of all ESPP purchase rights granted on or prior to July 1, 2011 have been estimated at the date of grant using a Black-Scholes-Merton option-pricing model with the following weighted average assumptions:

The fair value of each RSU is the market price of our stock on the date of grant. The aggregate value of RSUs that became fully-vested during 2011 and 2010 was $23 million and $43 million, respectively, determined as of the vest date. RSUs are generally payable in an equal number of shares of the Company’s common stock at the time of vesting of the units. The grant-date fair value of the shares underlying the restricted stock awards at the date of grant was $26 million, $45 million and $19 million in 2011, 2010 and 2009, respectively. These amounts are being recognized to expense over the corresponding vesting periods. For purposes of valuing these awards, the Company has assumed a forfeiture rate of 1.82%, 1.55%, and 0.0% during 2011, 2010, and 2009, respectively, based on a historical analysis indicating forfeitures for these types of awards.
 
Stock Repurchase Program
 
The Company’s Board of Directors previously authorized the repurchase of $750 million of common stock in open market transactions under a stock repurchase program through March 31, 2013. Since the inception of this program in 2005, through July 1, 2011, the Company has repurchased 20 million shares of its common stock for a total cost of $334 million. The Company repurchased 1.8 million shares for a total cost of $50 million during 2011. The Company may continue to repurchase stock as the Company deems appropriate and market conditions allow. The Company expects stock repurchases to be funded principally by operating cash flows.
 
Stock Purchase Rights
 
On April 6, 2001, the Company adopted a plan to protect shareholders’ rights in the event of a proposed takeover of the Company (the “2001 Rights Plan”). The 2001 Rights Plan expired on April 6, 2011. During the term of the 2001 Rights Plan, each share of the Company’s outstanding common stock carried one Right to Purchase Series A Junior Participating Preferred Stock (the “Right”). The Right enabled the holder, under certain circumstances, to purchase Series A Junior Participating Preferred Stock of Western Digital at an exercise price of $50.00 per share ten days after a person or group publicly announced it had acquired or had tendered an offer for 15%, or more, of the Company’s outstanding common stock. The Rights were redeemable by the Company at $0.001 per Right.

Remaining net undistributed earnings from foreign subsidiaries at July 1, 2011 on which no U.S. tax has been provided amounted to $4.7 billion. The net undistributed earnings are intended to finance local operating requirements and capital investments. Accordingly, an additional U.S. tax provision has not been made on these earnings. The tax liability for these earnings would be $1.6 billion if the Company repatriated the $4.7 billion in undistributed earnings from the foreign subsidiaries.

The increase in NOL benefits relates to the current year stock based compensation deductions which will result in a future benefit of $17 million. This $17 million will be recorded as a credit to shareholders’ equity when an incremental benefit is recognized after considering all other tax attributes available to the Company.

Tax Holidays and Carryforwards
 
A substantial portion of the Company’s manufacturing operations in Malaysia, Singapore and Thailand operate under various tax holidays and tax incentive programs which will expire in whole or in part at various dates through 2023. Certain of the holidays may be extended if specific conditions are met. The net impact of these tax holidays and tax incentives was to increase the Company’s net earnings by $362 million ($1.54 per diluted share), $560 million ($2.40 per diluted share), and $241 million ($1.07 per diluted share) in 2011, 2010, and 2009, respectively.
 
As of July 1, 2011, the Company had federal and state NOL carryforwards of $185 million and $52 million, respectively. In addition, as of July 1, 2011, the Company had various federal and state tax credit carryforwards of $251 million combined. The NOL carryforwards available to offset future federal and state taxable income expire at various dates from 2021 to 2030 and 2015 to 2020, respectively. Approximately $140 million of the credit carryforwards available to offset future taxable income expire at various dates from 2012 to 2030. The remaining amount is available indefinitely. NOLs and credits relating to Komag, Incorporated (“Komag”), which was acquired by the Company on September 5, 2007, are subject to limitations under Section 382 and 383 of the Internal Revenue Code. The Company does not expect these limitations to result in a reduction in the total amount of NOLs and credits ultimately realized.
 
Uncertain Tax Positions
 
The Company recognizes liabilities for uncertain tax positions based on a two-step process. First, the tax position is evaluated for recognition by determining if it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to be recognized in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. With the exception of certain unrecognized tax benefits that are directly associated with the tax position taken, unrecognized tax benefits are presented gross in the Company’s balance sheet. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. As of July 1, 2011, such interest and penalties were not material.
 
As of July 1, 2011, the Company had $245 million of unrecognized tax benefits.

The entire balance of unrecognized tax benefits at July 1, 2011, if recognized, would affect the effective tax rate.
 
The Company files U.S. Federal, U.S. state, and foreign tax returns. For both federal and state tax returns, with few exceptions, the Company is subject to examination for fiscal years 2008 through 2011. In foreign jurisdictions, with few exceptions, the Company is subject to examination for all years subsequent to fiscal 2006. The Company is no longer subject to examination by the Internal Revenue Service (“IRS”) for periods prior to 2006, although carry forwards generated prior to those periods may still be adjusted upon examination by the IRS or state taxing authority if they either have been or will be used in a subsequent period.
 
The IRS is currently examining fiscal years 2006 and 2007 for the Company and calendar years 2005 and 2006 for Komag. The IRS has completed its field work and proposed certain adjustments. Certain issues have been agreed upon by the Company and the IRS and certain issues remain unresolved. The Company has received Revenue Agent Reports (“RARs”) for the agreed issues. The Company has also received RARs from the IRS for the unresolved issues which seek adjustments to income before income taxes of $970 million for the Company and $380 million for Komag. The issues in dispute relate primarily to transfer pricing and certain other intercompany transactions. The Company disagrees with the proposed adjustments. In May 2011, the Company filed a protest with the IRS Appeals Office regarding the proposed adjustments. The Company is continuing discussions with the IRS to resolve the Komag issues.
 
The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of July 1, 2011, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s uncertain tax positions.
 
Note 10.  Fair Value Measurements
 
Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:
 
Level 1.  Quoted prices in active markets for identical assets or liabilities.
 
Level 2.  Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
 
Level 3.  Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.

impairment charges, $27 million of employee termination benefits and $4 million of contract termination and other exit costs. Total cash expenditures related to the restructuring activities were $31 million. The asset impairment charge of $81 million consisted of $76 million primarily related to the land, buildings, machinery and equipment at the manufacturing facilities in Thailand and Malaysia and $5 million related to a customer relationship intangible asset acquired from Komag. The impairment charge is based on the excess of the carrying values over the estimated fair values of the assets.

Note 14.   Acquisitions
 
Planned Acquisition of Hitachi Global Storage Technologies
 
On March 7, 2011, the Company entered into a stock purchase agreement (the “Purchase Agreement”) with Hitachi, Ltd. (“Hitachi”), Viviti Technologies Ltd., until recently known as Hitachi Global Storage Technologies Holdings Pte. Ltd., a wholly owned subsidiary of Hitachi (“HGST”), and Western Digital Ireland, Ltd., an indirect wholly owned subsidiary of the Company (“WDI”). Pursuant to the Purchase Agreement, WDI agreed to acquire all of the issued and outstanding paid-up share capital of HGST from Hitachi. The planned acquisition is intended to result in a more efficient and innovative customer-focused storage company, with significant operating scale, strong global talent and the industry’s broadest product lineup backed by a rich technology portfolio. The aggregate purchase price of the planned acquisition is estimated to be approximately $4.3 billion, due at closing, and will be funded with existing cash, new debt, and 25 million newly issued shares of the Company’s common stock. The Purchase Agreement contains certain termination rights for both the Company and Hitachi, including the right to terminate the Purchase Agreement if the planned acquisition has not closed by March 7, 2012. If the planned acquisition has not closed by March 7, 2012 due to the failure to receive any required antitrust or competition authority’s consent, approval or clearance or any action by any certain governmental entities to prevent the planned acquisition for antitrust or competition reasons, the Company will, concurrently with such termination, be required to pay Hitachi a fee of $250 million in cash. During 2011, the Company incurred $17 million of expenses related to the planned acquisition of HGST which are included within selling, general and administrative expense in the consolidated statements of income.
 
On March 7, 2011, in connection with the planned acquisition of HGST, the Company, WDTI and WDI entered into a commitment letter with Bank of America, N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated regarding a new credit facility for an amount of $2.5 billion, consisting of a $500 million revolving credit facility and $2.0 billion in term loans, to be entered into in connection with the closing of the planned acquisition (the “Senior Facility”). Since entering into the commitment letter, Bank of America N.A. and Merrill Lynch, Pierce, Fenner & Smith Incorporated led the effort to syndicate the Senior Facility for an amount of up to $3.0 billion, consisting of a $500 million revolving credit facility and up to $2.5 billion in term loans. As a result of such effort, the Company, WDTI and WDI have fully negotiated definitive loan documents for the Senior Facility with the syndicate members and, subject to customary closing conditions including completion of the acquisition in accordance with its terms, the Company, WDTI and WDI fully expect all of these syndicate members to be part of the final lender group. In addition, the Company is required to pay a commitment fee at the rate of 0.35%, per annum, of the aggregate unfunded amount committed to be borrowed under the Senior Facility. For 2011, the Company incurred debt commitment fees of $2 million related to the acquisition.
 
The planned acquisition of HGST is subject to several closing conditions, including the receipt of antitrust approvals or the expiration of applicable waiting periods in certain jurisdictions. The Company has received requests for
