PART I
 
Item 1.   Business
 
 
We design, develop, manufacture and sell hard drives. A hard drive is a device that uses one or more rotating magnetic disks (“magnetic media”) to store and allow fast access to data. Hard drives are key components of computers, including desktop and notebook computers (“PCs”), data storage subsystems and many consumer electronic (“CE”) devices.
 
We sell our products worldwide to original equipment manufacturers (“OEMs”) and original design manufacturers (“ODMs”) for use in computer systems, subsystems or CE devices, and to distributors, resellers and retailers. Our hard drives are used in desktop computers, notebook computers, and enterprise applications such as servers, workstations, network attached storage, storage area networks and video surveillance equipment. Additionally, our hard drives are used in CE applications such as digital video recorders (“DVRs”), and satellite and cable set-top boxes (“STBs”). We also sell our hard drives as stand-alone storage products and integrate them into finished enclosures, embedding application software and offering the products as WD®-branded external storage appliances for personal data backup and portable or expanded storage of digital music, photographs, video and other digital data.
 
Hard drives provide non-volatile data storage, which means that the data remains present when power is no longer applied to the device. Our hard drives currently include 3.5-inch and 2.5-inch form factor drives, having capacities ranging from 40 gigabytes (“GB”) to 2 terabytes (“TB”), nominal rotation speeds up to 10,000 revolutions per minute (“RPM”), and offer interfaces including both Enhanced Integrated Drive Electronics (“EIDE”) and Serial Advanced Technology Attachment (“SATA”). We also embed our hard drives into WD®-branded external storage appliances using interfaces such as USB 2.0, external SATA, FireWiretm and Ethernet network connections with capacities of 160 GB up to 8 TB. In addition, we offer a family of hard drives specifically designed to consume substantially less power than standard drives, utilizing our WD GreenPower Technologytm.
 
In the second quarter of 2009, we began to design, develop, manufacture and sell media players. A media player is a device that connects to a user’s television or home theater system and plays digital movies, music and photos from any of our WD®-branded external hard drives or other USB mass storage devices. We sell our media players worldwide to resellers and retailers under our WD® brand.
 
In the third quarter of 2009, with the acquisition of SiliconSystems, Inc. (“SiliconSystems”), we began to design, develop, manufacture and sell solid-state drives. A solid-state drive is a storage device that uses semiconductor, non-volatile media, rather than magnetic disks and magnetic heads, to store and allow fast access to data. We sell our solid-state drives worldwide to OEMs and distributors for use in the embedded systems market which includes network-communications, industrial, embedded-computing, medical, military, aerospace, media-appliance and data-streaming applications.
 
 
Our business strategy is to provide a broad selection of reliable, high quality hard drives at a low total cost of ownership and with high efficiency and speed. We believe this strategy helps accomplish the following:
 
  •  distinguishes us in the dynamic and competitive hard drive industry;
 
  •  provides great value to our customers;
 
  •  allows us to better achieve consistent financial performance, including strong returns on invested capital; and
 
  •  provides continued diversification of our hard drive product set and entry into additional markets such as solid-state drives and media players.
 
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 design, develop and manufacture hard drives for the desktop and mobile PC, enterprise, CE and branded product retail markets. We believe that growth in the sales of hard drives has continued to outpace the growth in the sales of all PCs as there were approximately 84% more hard drives sold in the market than PCs in calendar 2008, based on industry data. We believe the following factors continue to drive this accelerating growth of hard drive sales in addition to PC applications:
 
  •  consumer use of hard drives for the playing, retention and creation of digital content for personal use in the rapidly growing CE market;
 
  •  growth of the external hard drive or branded products market, permitting the easy storage, portability and backup of digital data such as music, photographs or video;
 
  •  increased use of multiple hard drives in PCs for data backup and expanded storage capacity; and
 
  •  increased use of multiple cost-optimized high performance hard drives in data-intensive applications such as Internet search engines and in hard drive intensive hosts for handheld computing devices.
 
Additionally, we believe that the demand for 2.5-inch hard drives has grown from approximately 16% of the overall hard drive market in calendar 2003 to 41% of the overall hard drive market in calendar 2008, driven by the fast-growing markets for notebook and netbook computers, game consoles and external storage.
 
We design, develop and manufacture solid-state drives for the embedded systems market which includes network-communications, industrial, embedded-computing, medical, military, aerospace, media appliance and data streaming applications. We believe that the growth rate of solid-state drives will be significant over the next four years, with particular opportunities for growth in the enterprise storage, netbooks, and embedded systems markets.
 
We also design, develop and manufacture WD®-branded media players for the retail market. We believe there is a growing need for consumers to play their stored digital content on their television or home theater system in connection with the growing trend in the digitization of rich content and data.
 
These factors and our product expansion strategy have gradually increased our percentage of revenue derived from non-desktop sources. In 2009, 62% of our revenue was from non-desktop sources compared to 56% in 2008.
 
For an additional discussion of risks relating to the hard drive industry, please see Item 1A of this Annual Report on Form 10-K.
 
 
The desktop PC market consists of the overall hard drive market for desktop computers. Individuals use desktop computers in homes, businesses and multi-user networks. Desktop computers use software applications for word processing, spreadsheet, desktop publishing, database management, multimedia, entertainment and for other needs. Hard drives store desktop computer operating system and application software, as well as the data used by the applications.
 
We believe that the demand for hard drives in the desktop PC market has grown in part due to:
 
  •  the overall growth of desktop computer sales;
 
  •  the increasing needs of businesses and individuals for increased storage capacity on their desktop computers;
 
  •  the continuing development of software applications to manage multimedia content; and
 
  •  the increasing use of broadband Internet, including content downloaded from the Internet onto desktop computer hard drives.
 
We believe several other factors affect the rate of desktop computer unit growth, including growth of notebook and netbook computers, maturing desktop PC markets in North America and Western Europe, an increase in first-time buyers of desktop computers in Asia, Eastern Europe and Latin America, and the lengthening of desktop computer replacement cycles.

The mobile PC market consists primarily of notebook and netbook computers. Individuals use mobile computers both in and away from homes and businesses. Like desktop computers, mobile computers use software applications for various needs and hard drives store notebook operating system and application software, and the data used by the applications.
 
We believe that the demand for hard drives in the mobile PC market has grown in part due to:
 
  •  the overall growth of mobile sales, including increased transition from desktop computers to mobile computers;
 
  •  the increased mobility of the workforce;
 
  •  the increasing needs of businesses and individuals for increased storage capacity on their notebook computers;
 
  •  the continuing development of software applications to manage multimedia content; and
 
  •  the increasing use of broadband Internet, including content downloaded from the Internet onto notebook hard drives.
 
We expect the mobile PC market to continue to grow faster than the desktop or enterprise markets in the next three years. As the mobile PC market continues to evolve to a higher volume market, we believe customers are placing increased emphasis on attributes such as quality, availability, reliability, execution, flexibility, capacity, performance, power and the competitive cost structures of their hard drive suppliers. These are the same attributes that have been emphasized for many years by customers in the high-volume desktop PC market.
 
 
The enterprise market for hard drives includes workstations, servers, network attached storage, storage area networks, other computing systems or subsystems, and video surveillance. Historically, hard drives for this market have utilized several interfaces, including the Small Computer Systems Interface (“SCSI”) and Fibre Channel Arbitrated Loop (“FC-AL”). Beginning in 2003, these traditional enterprise interfaces have been supplemented or replaced in certain storage applications by hard drives featuring the Serial Attached SCSI (“SAS”) interface technology, which is supported by industry standards, as well as by SATA. SATA hard drives typically cost customers less than SCSI hard drives while offering higher capacities and maintaining similar reliability, scalability and performance.
 
We believe that enterprise uses of SATA hard drives will continue to increase. During the past few years, a new disk-based back-up application has emerged with high-capacity SATA hard drives augmenting SCSI and SAS hard drives, tape and optical media. This new application, popularly referred to as “near-line” storage, has created a growth market because hard drives back up or access data more quickly than tape or optical solutions, and quickly retrieve critical back-up or near-line data. The availability of SATA hard drive solutions, which are more cost effective than SCSI and SAS hard drives, promotes the increasing use of high-capacity hard drives in near-line storage applications. The low price per capacity of SATA drives has stimulated new applications such as video surveillance, video editing/broadcasting and medical imaging. These applications represent segments of a growing market for high capacity storage in non-computing imaging and multimedia professions.
 
Enterprise-class SATA drives are becoming commonplace for IT infrastructure applications such as databases, scientific computing, web content, web caching, web search engines and electronic mail. These applications have become an important market for high-capacity SATA hard drives. We believe that this market will consume a growing portion of the highest capacity hard drives in the next three years.
 
SAS is the next generation SCSI technology and has been replacing SCSI drives over the past few years. SATA technology is compatible with SAS technology, enabling customers the flexibility of incorporating SATA hard drives in SAS storage systems. We believe the market transition from SCSI to SAS has added to the growth of the enterprise-class SATA market, which currently is estimated to be approximately 47% of the enterprise hard drive market.
 
High-performance server applications, including blade servers, are increasingly using 2.5-inch form factor hard drives, supplanting traditional 3.5-inch drives. Smaller form factors enable more drives per physical space for increased

performance, higher capacity per square foot and lower power consumption. This trend demonstrates the fragmentation of the enterprise hard drive market and the need for application-specific enterprise-class hard drives.
 
 
The use of hard drives in CE products has been a major growth area in recent years. Currently, the three largest segments of this market are:
 
  •  video content in applications such as DVRs;
 
  •  audio and video content in applications such as consumer handheld devices, including MP3 players; and
 
  •  hard drives in game consoles.
 
Since 1999, DVRs have been available for use in home entertainment systems and they offer 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. Additionally, digital video disk (“DVD”) recorders increasingly incorporate hard drives to allow for DVR functionality and faster recording of content onto removable DVDs. The market for these products favors larger capacity hard drives and continues to grow in Japan, North America and Europe. Additionally, the rest of Asia Pacific shows strong interest in this market. We believe growth in this market will continue to build demand for higher capacity hard drives.
 
The proliferation in the CE market of more sophisticated mobile devices including cell phones and MP3 players is driving the delivery of diverse content from hard drive intensive hosts. We believe this is one of the factors influencing increased sales of enterprise-class SATA drives. We also believe that multimedia handheld devices such as video cameras and high-resolution still cameras are enabling consumer production of expansive digital content that requires increasing amounts of small form-factor hard drive storage, as well as high-capacity desktop-class hard drives for editing, manipulation and long-term storage of such content.
 
Hard drives with 1.8-inch or 1.0-inch form factors primarily address the consumer handheld device and portable external storage markets. The majority of hard drives used in portable media players that play both digital audio and video content are 1.8-inch form factors. Currently, we believe the markets for these handheld devices are better served by flash memory as opposed to rotating magnetic storage.
 
 
Most new PC systems include high-speed external interfaces, such as USB 2.0, external SATA, FireWiretm or Ethernet network connections, that permit users to supplement the storage space of their PC systems or home and small office networks with the use of external hard drives. Users store additional programs or multimedia content, and back up internal hard drives with external hard drives, as well as mobile external hard drives for mobility convenience. Although external hard drives are a small part of the overall hard drive market, we believe that sales of external hard drives will continue to grow. External storage can often be the easiest, quickest or only way of adding additional storage capacity to either a desktop or notebook computer. We believe there is an increasing consumer awareness of the need and value of securely storing personal digital content through backup applications and devices. In addition, there is opportunity for external storage as a way of expanding storage capacity in CE devices such as DVRs. We also believe there is a growing need for media players that enable consumers to play digital movies, music and photos, otherwise limited to being viewed on computer screens, from USB mass storage devices on their television or home theater system.
 
 
The solid-state drive market consists primarily of solid-state drives constructed with semiconductor, non-volatile media that retains data even when power is not applied using either single-level cell or multilevel cell NAND media. Our solid-state drive products are currently used in the embedded systems market which includes network-communications, industrial, embedded-computing, medical, military, aerospace, media appliance and data streaming applications.
 
We believe that the demand for solid-state drives in certain markets has grown in part due to:
 
  •  the increasing performance, measured by input/output per second, in enterprise applications;


7


Table of Contents

 
  •  the increasing low entry cost applications in the netbook markets;
 
  •  the increasing premium performance applications in the desktop and notebook markets; and
 
  •  the increasing requirements of the embedded systems market for high durability and long life cycles.
 
We expect the solid-state drive market to grow faster on a compounded annual growth rate basis than the hard drive market over the next four years.
 
 
We regularly review opportunities to apply our knowledge of data storage technology to markets that we do not currently serve. Based on significant investments we made over the last five years, we believe we have the technology building blocks to increase our overall market penetration and be a full-line hard drive 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.
 
 
We offer a broad line of hard drives designed for various markets. We market our hard drives under brand names including WD Caviar, WD RE, WD VelociRaptor, WD Scorpio, WD Elements, WD AV, My Passport, My Book, My DVR Expander and WD GreenPower Technology.

We also offer a line of WD®-branded media players under the WD TVtm brand name, as well as a line of solid-state drives under the SiliconDrive® brand name.
 
 
The hard drives we design for the desktop PC market currently consist of 3.5-inch form factor products with capacities ranging from 40 GB to 2 TB. These products utilize either the EIDE or SATA interfaces, providing high performance while retaining ease of use and overall low cost of connection. The type of EIDE interface currently used in our hard drives is ATA/100, which signifies a burst data transfer rate of 100 megabytes per second, which is the maximum specified data transition that can be sustained under ideal conditions. The SATA interface available in the majority of our hard drives enables burst transfer rates of up to 3 gigabits (Gb) per second.
 
 
Our hard drives used in mobile products typically include 2.5-inch form factor drives for notebook computers. Although the desktop PC market still accounts for a majority of hard drive sales, unit shipments of hard drives for notebook computers represent a growing share of the total. We entered the 2.5-inch mobile market in September 2004. We are now shipping our seventh generation of the WD Scorpio® product family, offering up to 1 TB of capacity. Our product expansion, including a high-performance hard drive spinning at 7,200 RPM and producing ultra-high capacities for specific applications with a three platter platform, has enabled us to provide customers with a full-line of 2.5-inch mobile drives and helped us enhance our market position in this fast-growing market.

Research and development expenses totaled $509 million, $464 million and $306 million in 2009, 2008 and 2007, respectively.
 
Fiscal 2009 represented the eighth consecutive year of substantial growth in our research and development spending to support our significant broadening of our product and technology portfolios. Over that eight-year period, we grew our research and development spending 350% from $113 million in fiscal 2001 to $509 million in fiscal 2009. As a result of this investment activity, we continue to expand our business beyond the desktop PC market into newer markets or markets in which we have not previously participated. Such investments have allowed us to execute against our strategic objective of revenue diversification to address the growth of new applications for hard drives and fast-growing new market opportunities.

Hard drives record, store and retrieve digital data. Performance attributes of hard drives, such as their ability to access and transmit data and storage capacity, are currently better than removable or floppy disks, optical hard drives and tapes, and they are more cost effective than semiconductor technology. The primary measures of hard drive performance include:
 
  •  “Acoustics” — which is the 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” — which is the sustained rate of data transfer to and from the disk, commonly expressed in gigabits per second. One gigabit equals one billion bits.
 
  •  “Seek time” — which is the time needed to position the heads over a selected track on the disk surface, commonly expressed in milliseconds.
 
  •  “Spindle rotation speed” — which is the 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.
 
  •  “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.
 
  •  “Power Consumption” — which is the amount of electricity required to operate the drive, measured in watts.
 
All of our hard drive products employ similar technology. 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 (“disks”), head positioning mechanism (“actuator”) and spindle motor. A rigid base and top cover contain these components in a contamination-controlled environment. The PCBA includes both standard and custom integrated circuits, an interface connector to the host computer and a power connector.
 
HDA: 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, a pivot-arm module, on which the individual heads

Table of Contents

are mounted. Each disk has a head suspended directly above it, which can read data from or write data to the spinning disk.
 
PCBA: The integrated circuits on the printed circuit board typically include a drive interface and a controller. 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.
 
Industry-standard interfaces allow the hard drive to communicate with the computer. Currently, the primary interfaces for PCs are EIDE (Parallel Advanced Technology Attachment, or “PATA”) and SATA, and the primary interfaces for enterprise systems are SATA, SCSI, SAS, and FC-AL. As computer performance continues to improve, the hard drive will need to deliver information faster. We believe this will continue to drive the PC industry transition to higher speed interfaces, such as SATA and SAS, to facilitate the higher data transfer rates. We currently offer the SATA interface on our WD Caviar®, WD Scorpio® WD® RE, WD VelociRaptortm and WD® AV hard drive families; and EIDE (PATA) on WD Caviar®, WD Scorpio® and WD®AV families.
 
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, determines storage capacity of the hard drive. The higher the areal density, the more information can be stored on a single platter. Achieving a given drive capacity requires fewer disks and heads as the areal density increases, potentially reducing product costs over time through reduced component requirements. In January 2009, we began shipping our WD Caviar® 3.5-inch family of drives at 500 GB per platter (approximately 400 gigabits per square inch) areal density. In July 2009, we began shipping our WD Scorpio® Bluetm 2.5-inch 1 TB drives at 333 GB per platter (approximately 525 gigabits per square inch) areal density.
 
Head technology is one of the key components affecting areal density. Historically, there have been rapid technological changes resulting in several generations of head technology in a relatively short time. However, in recent years the time has lengthened between changes in generations of head technology. The hard drive industry has transitioned from the use of longitudinal magnetic recording (“LMR”) head technology for the head writer function to perpendicular magnetic recording (“PMR”) technology, which allows for significantly higher storage capacities. In addition, the industry has made the transition to tunnel-junction magneto resistive (“TMR”) technology for the head reader function. We have completed the transition to PMR and TMR across all of our product platforms.
 
With the transition to PMR, magnetic media plays a much more important role in achieving higher areal density. PMR demands a much tighter interaction and matching between head and magnetic media designs. We are vertically integrated in the two most important technology components of hard drives (heads and magnetic media), which has enabled us to achieve a more optimum design and utilization of these components.
 
We 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 record, store and retrieve digital data without any moving parts. Attributes, such as fast read/write speeds, low power consumption and robust durability offer greater performance than hard drives in some storage applications but are currently much more costly per gigabyte and are available in much lower capacity points than hard drives. The main components of a solid-state drive are the system-on-chip and semiconductor media. The capacity, measured in megabytes or gigabytes, of a solid-state drive is based on the total number of megabits or gigabits of semiconductor media in the solid-state drive. Industry-standard storage interface protocols, such as SATA, PATA/EIDE/CF and USB 2.0, allow the solid-state drive to communicate with the host system.
 
The WD® product lines generally leverage a common platform for various products within product families with different capacities to serve differing market needs. This platform strategy results in commonality of components across different products within product families and, in some cases, across product families, which reduces 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.

We sell our products globally to OEMs, ODMs, distributors and retailers. OEMs purchase our products, either directly or through a contract manufacturer such as an ODM, and assemble them into the computer or CE systems they build. Distributors typically sell our products to non-direct customers such as small computer and CE manufacturers, dealers, systems integrators, online retailers and other resellers. Retailers typically sell our products directly to end-users through their storefront or online facilities.
 
 
Sales to OEMs, which include sales through ODMs, accounted for 54%, 51% and 48% of our net revenue in 2009, 2008 and 2007, respectively. For 2009 and 2007, sales to Dell Inc. accounted for 10% of our net revenue. For 2008, no single customer accounted for 10%, or more, of our net revenue. We believe that our success depends on our ability to maintain and improve our strong relationships with the leading OEMs.
 
OEMs evaluate and select their hard drive and solid-state drive suppliers based on a number of factors, including quality and reliability, storage capacities, performance characteristics, price, service and support, ease of doing business, and the supplier’s long-term financial stability. They typically seek to qualify two or more providers for each generation of products, and once an OEM has chosen its qualified vendors for a given product, it generally will purchase products from those vendors for the life of that product. To achieve success with OEM qualifications, a supplier must consistently offer products featuring leading technology, quality and reliability at acceptable capacity. Suppliers must quickly achieve volume production of each new generation of high quality and reliable hard drives or solid-state drives, requiring access to flexible, high-capacity, high-quality manufacturing capabilities.
 
Many of our OEM customers utilize just-in-time inventory management processes or supply chain business models that combine “build-to-order,” in which they do not build until there is a firm order, and “contract manufacturing,” in which the OEM contracts assembly work to a contract manufacturer, such as an ODM, who purchases components and assembles the computer based on the OEM’s instructions. For certain OEMs, we maintain a base stock of finished goods inventory in facilities located near or adjacent to the OEM’s operations.
 
For an additional discussion of risks related to our need to adapt to our customers’ business models and maintain customer satisfaction, refer to Item 1A of this Annual Report on Form 10-K.
 
 
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 accounted for approximately 26%, 31% and 36% of our net revenue for 2009, 2008 and 2007, respectively. Distributors generally enter into non-exclusive agreements for specific territories with us for the purchase and redistribution of our products in those territories. We grant our distributors limited price protection rights.
 
 
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. Retailers accounted for approximately 20%, 18% and 16% of our net revenue for 2009, 2008 and 2007, respectively. Our current retail customer base is primarily in the United States (“U.S.”), Canada and Europe. The retail channel complements our other sales channels while helping to build brand awareness for WD and our products. Retailers supply end-users with our products to upgrade their computers, externally store their data for backup or mobility purposes and play their stored digital content on their television or home theater systems. We grant our retailers price protection and limited rights to return product on an inventory rotation basis. We also sell our branded products through our web site.

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 U.S. companies but do not include sales to U.S. subsidiaries of foreign companies, represented 80%, 76% and 68% of our net revenue for 2009, 2008 and 2007, 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 an additional discussion regarding the risks related to sales to international customers, see Item 1A of this Annual Report on Form 10-K.
 
For additional information concerning 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.
 
We perform our marketing and advertising functions internally and through outside firms. We target advertising, worldwide packaging and marketing materials to various reseller and end-user categories. We utilize both consumer media and trade publications. We have programs under which we reimburse qualified distributors and retailers for certain marketing expenditures. We also maintain customer relationships by communicating with our resellers and providing end-users with information and support through our web site.
 
 
We compete primarily with manufacturers of hard drives for use in desktop, notebook, enterprise, CE and external storage products. Our competitors in the hard drive market include companies such as Fujitsu Limited (which has announced that the transfer of its hard drive business to Toshiba has been delayed until September 2009), Hitachi Global Storage Technologies, Samsung Electronics Co. Ltd., Seagate Technology and Toshiba Corporation.
 
The hard drive industry is intensely competitive, with hard drive suppliers competing for sales to a limited number of major customers. Hard drives manufactured by different competitors are highly substitutable due to the industry mandate of technical form, fit and function standards. 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. We believe that we are generally competitive in all of these factors.
 
We believe that there are no substantial barriers for existing competitors to offer competing products. Therefore, we believe that we cannot differentiate WD® hard drive products solely on attributes such as storage capacity, buffer size or time-to-market. Accordingly, we differentiate WD by focusing on operational excellence, high product quality and reliability, and designing and incorporating into our hard drives desirable product performance attributes. Such performance attributes include seek times, data transfer rates, intelligent caching, failure prediction, remote diagnostics, acoustics, error recovery, low operating temperature, low power consumption and optimized streaming capabilities.
 
In addition, we differentiate WD by emphasizing non-product related attributes, including rapid response to our customers. Rapid response requires accelerated design cycles, customer delivery, production flexibility and timely service and support, which contribute to customer satisfaction. We also rely on the strength of the WD brand name with value-added resellers, retailers and solution providers to whom we sell our hard drive products directly and indirectly. 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 hard drive, particularly in a rapidly changing technology environment.
 
Advances in magnetic, optical or other data storage technologies could result in competitive products 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.
 
High-speed semiconductor media competes with hard drive products in some applications, such as consumer handheld devices and portable external storage. Semiconductor media is much faster in some applications than magnetic hard drives, but currently is not competitive in most applications using 3.5-inch and 2.5-inch form factor hard drives

Table of Contents

from a cost standpoint. Flash memory, a non-volatile semiconductor media, is currently much more costly and, while it has higher “read” performance attributes than hard drives, it has lower “write” performance attributes. Flash memory could become more competitive in the near future for additional applications requiring less storage capacity than that provided by hard drives. However, we believe that the traditional high-volume computing markets will remain the domain of 3.5-inch and 2.5-inch hard drives based on the hard drive industry’s attributes of reliability, availability and cost.
 
Our competitors in the external hard drive market include companies such as EMC Corporation, Hitachi Global Storage Technologies, LaCie Group, Melco Holdings Inc. and Seagate Technology. Our competitors in the solid-state drive market include companies such as Intel Corporation, Micron Technology, Inc., Smart Modular Technologies, Inc., STEC, Inc., and Samsung Electronics Co. Ltd.
 
For an additional discussion of risks related to competition, see Item 1A of this Annual Report on Form 10-K.
 
 
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, including Africa, Asia Pacific, Australia, Europe, India, Latin America, the Middle East and North America to provide various levels of testing, processing and/or recertification of returned products for our customers. In addition, we receive and service returned hard drives at our U.S. facility.
 
 
We believe that we have significant know-how, unique product manufacturing processes, execution skills and human resources to continue to be successful and have the ability to grow, as necessary, our manufacturing operations. To be competitive, we must manufacture high quality hard drives with industry leading time-to-volume production at competitive unit costs. We strive to maintain manufacturing flexibility, high manufacturing yields, reliable products, and high-quality components that we manufacture ourselves, while insisting that our suppliers provide high-quality components at competitive prices. The critical elements of our hard drive production are high volume, low cost assembly and testing, and establishment and maintenance of key supplier relationships. By establishing close relationships with our strategic component suppliers, we believe we access best-of-class technology and manufacturing quality. In addition, 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.
 
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 manufacture hard drives in Malaysia and Thailand. 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 use our wafer fabrication facilities in Fremont, California and our slider fabrication facility in Bang Pa-In, Thailand, to design and manufacture a substantial portion of the heads and head gimbal assemblies (“HGAs”) we include in the hard drives we manufacture. We have deferred the completion of converting our head wafer fabrication facilities in Fremont, California to utilize 8-inch wafers from 6-inch wafers as a result of macroeconomic conditions.
 
We also have magnetic media and substrate design and manufacturing facilities in Malaysia. We use these facilities to design and manufacture most of the magnetic media and substrates that we use in our products.
 
We leverage the efficiencies of contract manufacturers when strategically advantageous.

The following products are the major components currently used in the manufacture of our hard drives:
 
  •  magnetic heads and magnetic media;
 
  •  suspensions with related HGAs and 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 also use several other components in our hard drives such as seals, filters, plastic molded parts, capacitors, resistors, connectors and cables.
 
We design and manufacture a substantial portion of the heads, magnetic media and substrates required for the hard drives we manufacture. We purchase a portion of these components from third party suppliers. 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 player, the controller, are acquired from third party suppliers.
 
We generally retain multiple suppliers for each of our component requirements but in some instances use sole sources for business reasons.
 
For an additional discussion of risks related to our component supplies, see Item 1A of this Annual Report on Form 10-K.
 
 
A substantial portion of our orders are generally for shipments within 30 to 60 days of the placement of the order. We generally negotiate pricing, order lead times, product support requirements and other terms and conditions before receiving a customer’s first purchase order for a product. 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, we make many of our sales to OEMs under just-in-time delivery contracts that do not generally require firm order commitments by the customer until the time of sale. Instead, we receive a periodic forecast of requirements from the customer and invoice the customer upon shipment of the product from the just-in-time warehouse. 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 earlier periods.
 
 
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.
 
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

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 additional discussion of risks related to environmental regulation, see Item 1A of this Annual Report on Form 10-K.
 
 
As of July 3, 2009, we employed a total of 45,991 employees worldwide. This represents a decrease in headcount of approximately 8% since June 27, 2008 and an increase of approximately 56% since June 29, 2007. 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 and most of our competitors nevertheless have difficulty at times hiring and retaining certain skilled employees. We have engaged consultants and contract personnel to fill these needs until full-time employees could be recruited. We consider our employee relations to be good. For additional discussion of risks related to our skilled employees, see Item 1A of this Annual Report on Form 10-K.

Item 1A.   Risk Factors
 
 
If the current worldwide economic downturn continues, many of our direct and indirect customers may delay or reduce their purchases of our products and systems containing our products. In addition, many of our customers in each of the OEM, distribution and retail channels rely on credit financing in order to purchase our products. If the negative conditions in the global credit markets prevent our customers’ access to credit, product orders in these channels may decrease, which could result in lower revenue. Likewise, if our suppliers face challenges in obtaining credit, in selling their products or otherwise in operating their businesses, they may become unable to offer the materials we use to manufacture our products. These actions could result in reductions in our revenue, increased price competition and increased operating costs, which could adversely affect our business, results of operations and financial condition.
 
 
The current negative worldwide economic conditions and market instability make it increasingly difficult for us, our customers and our suppliers to accurately forecast future product demand trends, which could cause us to produce excess products that can depress product prices, increase our inventory carrying costs and result in obsolete inventory. Alternatively, this forecasting difficulty could cause a shortage of products, or materials used in our products, that could result in an inability to satisfy demand for our products and a loss of market share. For a further discussion of these risks, please see the risk factor below entitled “Our failure to accurately forecast market and customer demand for our products could adversely affect our business and financial results or operating efficiencies.”
 
 
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; however, as a result of the current negative worldwide economic conditions, 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, if global economic conditions worsen, the risk increases 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.

As we previously announced, we committed to a business restructuring plan intended to realign our cost structure with a softer demand environment. If the worldwide economic downturn worsens and demand were to soften further, we may be forced to execute additional restructuring activities to realign our cost structure with softening demand. Additional restructuring activities could result in impairment charges and other expenses in excess of what we anticipated when we previously announced our restructuring plan, either of which could adversely impact our results of operations or financial condition.
 
 
If the current worldwide economic downturn continues, it 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.
 
 
Historically, the hard drive industry has experienced declining ASPs. Our ASPs tend to decline when competitors lower prices as a result of decreased costs or to absorb excess capacity, liquidate excess inventories, restructure or attempt to gain market share. Our ASPs also 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. When ASPs in the hard drive industry decline, our ASPs are also likely to decline, which adversely affects our operating results.
 
 
During past economic downturns, as well as over the past few years, the consumer market for computers has shifted significantly towards lower priced systems, and we therefore expect this trend to continue in light of the current negative worldwide macroeconomic conditions. If we are not able to continue to offer a competitively priced hard drive for the low-cost PC market, our share of that market will likely fall, which could harm our operating results. The market for hard drives is also fragmenting into a variety of devices and products. Many industry analysts expect, as do we, that as content increasingly converts to digital technology from the older analog technology, the technology of computers and consumer electronics will continue to converge, and hard drives may be found in many products other than computers, such as various CE devices. Accurately forecasting for future requirements of these new markets remains challenging.
 
Moreover, some devices such as personal video recorders and digital video recorders, or some new PC operating systems which allow greater consumer choice in levels of functionality and therefore greater market differentiation, may require attributes not currently offered in our products, resulting in a need to develop new interfaces, form factors, technical specifications or product features, increasing our overall operational expense without corresponding incremental revenue at this stage. If we are not successful in continuing to deploy our hard drive technology and expertise to develop new products for emerging markets such as the CE market, or if we are required to incur significant costs in developing such products, it may harm our operating results.
 
 
Demand for our hard drives depends 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 intense price competition. If intense price competition occurs, we may be forced to lower prices sooner and more than expected, which could result in lower revenue and gross margins.

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. If our forecasts exceed actual market demand, or if market demand decreases significantly from our forecasts, then we could experience periods of product oversupply and price decreases, which could impact our financial performance. If our forecasts do not meet actual market demand, or 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.
 
Although we receive forecasts from our customers, they are not generally obligated to purchase the forecasted amounts. Sales volumes in the distribution and retail channels are volatile and harder to predict than sales to our OEM or ODM customers. We consider these forecasts in determining our component needs and our inventory requirements. If we fail to accurately forecast our customers’ product demands, we may have inadequate or excess inventory of our products or components, which could adversely affect our operating results.
 
In order to efficiently and timely meet the demands of many of our OEM customers, we position our products in multiple strategic locations based on the amounts forecasted by such customers. If an OEM customer’s actual product demands decrease significantly from its forecast, then we may incur additional costs in relocating the products that have not been purchased by the OEM. This could result in a delay in our product sales and an increase in our operating costs, which may negatively impact our operating results.
 
 
Historically, the industry has experienced periods of variable areal density growth rates. When the rate of areal density growth increases, the rate of increase may exceed the increase in our customers’ demand for aggregate storage capacity. Furthermore, our customers’ demand for storage capacity may not continue to grow at current industry estimates as a result of developments in the regulation and enforcement of digital rights management, the emergence of processes such as cloud computing, data deduplication and storage virtualization, or otherwise. 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, our ASPs could decline, which could adversely affect our operating results.
 
 
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 must make necessary adaptations to our business model to address these complexities. For example, as we have previously disclosed, we have been investing in technology to develop and support a product line to sell to mainstream enterprise market customers. In addition to requiring significant capital expenditures, our entry into the mainstream 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 mainstream enterprise market, while maintaining a competitive operating cost model. If we fail or are delayed in our attempts to enter into the mainstream enterprise storage market, we will remain at a competitive disadvantage to the companies that serve this market and our ability to continue our growth will be negatively affected.
 
 
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.
 
 
While we continue to develop new products and look to expand into new markets, the success of our new product introductions depends on a number of factors, including our ability to anticipate and manage a variety of issues associated with these new products and new markets, such as:
 
  •  difficulties faced in manufacturing ramp;
 
  •  market acceptance;
 
  •  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.
 
Further, we need to identify how any of the new markets into which we are expanding may have different characteristics from the markets in which we currently exist and properly address these differences. These characteristics may include:
 
  •  demand volume requirements;
 
  •  demand seasonality;
 
  •  product generation development rates;
 
  •  customer concentrations;
 
  •  warranty expectations and product return policies; and
 
  •  cost, performance and compatibility requirements.
 
Our business may suffer if we fail to successfully anticipate and manage these issues associated with our product development and market expansion. For example, our branded products are designed to attach to and interoperate with a wide variety of PC and CE devices, and therefore their functionality relies on the manufacturer of such devices, or the associated operating systems, enabling the manufacturer’s devices to operate with our branded products. If our branded products are not compatible with a wide variety of devices, or if device manufacturers design their devices so that our branded products cannot operate with them, and we cannot quickly and efficiently adapt our branded products to address these compatibility issues, our business could suffer.
 
 
The CE and retail markets have different seasonal pricing and volume demand cycles as compared to the PC market. By expanding into these markets, we became exposed to seasonal fluctuations that are different from, and in addition to, those of the PC market. For example, because the primary customer for our branded products are individual consumers, this market has historically experienced a dramatic increase in demand during the winter holiday season. If we do not properly adjust our supply to these new demand cycles, we risk having excess inventory during periods of low demand and insufficient inventory during periods of high demand, which could adversely affect our operating results.

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. If consumer spending continues to decrease as a result of the current worldwide economic downturn, our operating results could suffer because of the increased importance of our branded products business.
 
We sell our branded products directly to a select group of major retailers, such as computer superstores and CE stores, and authorize sales through distributors to other retailers and online resellers. Our current retail customer base is primarily in the U.S., Canada and Europe. We are facing increased competition from other companies for shelf space at a small number of major retailers that have strong buying power and pricing leverage. If we are unable to maintain effective working relationships with major retailers and online resellers, our competitive position in the branded product market may suffer and our operating results may be adversely affected. In addition, if customers no longer maintain a preference for WD®-brand products or if we fail to successfully expand into multiple channels, our operating results may be adversely affected.
 
Additionally, we face strong competition in maintaining and trying to grow our market share in the retail market, particularly because of the relatively low barriers to entry in this market. For example, several additional hard drive manufacturers have recently disclosed plans to expand into the external storage market, and as these companies attempt to gain market share, we may have difficulty in maintaining or growing our market share and there may be increased downward pressure on pricing. We will continue to introduce new products in the retail market that incorporate our disk drives; however, there can be no assurance that these products will gain market acceptance, and if they do not, our operating results could suffer.
 
 
During the year ended July 3, 2009, a large percentage of our revenue, 48%, 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. Even if we successfully qualify a product with a customer, the customer is not generally obligated to purchase any minimum volume of products from us and may be able to cancel an order or terminate its relationship with us at any time. 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.
 
 
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. We may be at a competitive disadvantage to any companies that are able to gain these advantages.

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. Additionally, continued industry consolidation may lead to uncertainty in areas such as component availability, which could negatively impact our cost structure.
 
 
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. If we fail to remain competitive in terms of our technology, quality, service and support, our distribution customers may favor our competitors, and our operating results could suffer. We also face significant risk in the distribution market for hard drives. If the distribution market weakens as a result of a slowing PC growth rate, technology transitions or a significant change in consumer buying preference from white box to branded PCs, or if we experience significant price declines due to oversupply in the distribution channel, then our operating results would be adversely affected.
 
 
The price of hard drives has fallen over time due to increases in supply, cost reductions, technological advances and price reductions by competitors seeking to liquidate excess inventories or attempting to gain market share. 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, taken together, may result in significant shifts in market share among the industry’s major participants. In addition, product recalls can lead to a loss of market share, which could adversely affect our operating results.
 
 
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.
 
 
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 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 latent


22

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. In addition, a product recall may damage our relationship with our customers, and we may 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. If these additional expenses are significant, it could adversely affect our business, financial condition and operating results.
 
 
A competitive cost structure for our products, including critical components, labor and overhead, is critical to the success of our business, and our operating results depend on our ability to maintain competitive cost structures on new and established products. If our competitors are able to achieve a lower cost structure that we are unable to match, we could be at a competitive disadvantage to those competitors.
 
 
Increases in the cost for certain commodity materials may increase our costs of manufacturing and transporting hard drives and key components. Shortages of materials such as stainless steel, aluminum, nickel, neodymium, ruthenium or platinum increase our costs and may result in lower operating margins if we are unable to find ways to mitigate these increased costs. For example, perpendicular recording technology requires increased usage of precious metals such as ruthenium and platinum, the price of which may continue to be volatile, which could adversely affect our operating margins. Furthermore, if other high volume industries increase their demand for materials such as these, our costs may further increase, which could have an adverse effect on our operating margins. The volatility in the cost of oil also affects our transportation costs and may result in lower operating margins if we are unable to pass these increased costs through to our customers.
 
 
We make most of our own heads and magnetic media for some of our product families; however, we do not manufacture many of the component parts used in our hard drives. As a result, 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 effectively manage our relationships with our major component suppliers. We must also effectively integrate different products from a variety of suppliers, each of which employs variations on technology, which can impact, for example, feasible combinations of heads and magnetic media components. For example, in August 2003, we settled litigation with a supplier who previously was the sole source of read channel devices for our hard drives. As a result of the disputes that gave rise to the litigation, our profitability was at risk until another supplier’s read channel devices could be designed into our products. Similar disputes with other strategic component suppliers could adversely affect our operating results.
 
 
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 sub-suppliers or their labor or environmental practices. The violation of labor, environmental or other laws by any of our suppliers or sub-suppliers, or divergence of a supplier’s or sub-supplier’s labor or environmental practices from those generally accepted as ethical in the U.S., could harm our business by:
 
  •  interrupting or otherwise disrupting the shipment of our product components;


23


Table of Contents

 
  •  damaging our reputation;
 
  •  forcing us to find alternate component sources;
 
  •  reducing demand for our products (for example, through a consumer boycott); or
 
  •  exposing us to potential liability for our supplier’s or sub-supplier’s wrongdoings.
 
 
Certain components are available from a limited number of suppliers, and we are sole sourced with some of these suppliers on certain products. Because we depend on a limited number of suppliers for certain product components and manufacturing equipment, each of the following could significantly harm our operating results:
 
  •  an unwillingness of a supplier to supply such components or equipment to us;
 
  •  an increase in the cost of such components or equipment;
 
  •  an extended shortage of required components or equipment;
 
  •  consolidation of key suppliers, such as the acquisition of Brilliant Manufacturing Limited by Nidec Corporation, the acquisition of Agere Systems Inc. by LSI Corporation, the acquisition of Infineon Technologies’ hard drive semiconductor business by LSI Corporation, the acquisition of Alps Electric Co. Ltd.’s magnetic device division’s assets and related intellectual property by TDK Corp, and the acquisition of Magnecomp Precision Technology Public Company Limited by TDK Corp;
 
  •  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, to adjust to market conditions, or to meet our quality, yield or production requirements.
 
 
Our future operating results may also 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. In addition, some of the components (or component types) used in our products are used in other devices, such as mobile telephones and digital cameras. If there is a significant simultaneous upswing in demand for such a component (or component type) from several high volume industries resulting in a supply reduction, if a component is otherwise in short supply, or if a supplier fails to qualify or has a quality issue with a component, we may experience delays or increased costs in obtaining that component. If we are unable to obtain sufficient quantities of materials used in the manufacture of magnetic components, or other necessary components, we may experience production delays which could cause us loss of revenue. If a component becomes unavailable, we could suffer significant loss of revenue.
 
In addition, certain equipment we use in our manufacturing or testing processes is available only from a limited number of suppliers. Some of this equipment uses 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.
 
 
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


24


Table of Contents

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 the current negative worldwide 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.
 
 
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 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.
 
 
Our vertical integration of head and magnetic media manufacturing resulted in a fundamental change in our operating structure, as we now manufacture heads and magnetic media for use in many of the hard drives we manufacture. Consequently, we make more capital investments and carry a higher percentage of fixed costs than we would if we were not vertically integrated. If the 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.
 
In addition, we may incur additional risks, including:
 
  •  failure to continue to leverage the integration of our magnetic media technology with our head technology;
 
  •  insufficient third party sources to satisfy our needs if we are unable to manufacture a sufficient supply of heads or magnetic media;
 
  •  third party head or magnetic media suppliers may not continue to do business with us or may not do business with us on the same terms and conditions we have previously enjoyed;
 
  •  claims that our manufacturing of heads or magnetic media may infringe certain intellectual property rights of other companies; and
 
  •  difficulties locating in a timely manner suitable manufacturing equipment for our head or magnetic media manufacturing processes and replacement parts for such equipment.
 
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.


25


Table of Contents

 
Under our business plan, we are developing and manufacturing a substantial portion of the heads and magnetic media used in some of 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. In addition, we may not have access to external sources of supply without incurring substantial costs which would negatively impact our business and 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.
 
 
New products in the hard drive market typically require higher areal densities than previous product generations, posing formidable technical and manufacturing challenges. Higher areal densities require existing head and magnetic media technology to be improved or new technology developed to accommodate more data on a single disk. In addition, our introduction of new products during a technology transition increases the likelihood of unexpected quality concerns. Our failure to bring high quality new products to market on time and at acceptable costs may put us at a competitive disadvantage to companies that achieve these results.
 
 
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 technologies, such as current-perpendicular-to-plane (“CPP”), energy assisted magnetic recording, patterned magnetic media and other similar potentially breakthrough technology, that will represent revolutionary recording technologies if they can be implemented by a competitor on a commercially viable basis ahead of the industry, which 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. For example, new recording technology requires changes in the manufacturing process of heads and magnetic media, which may cause longer production times and reduce the overall availability of magnetic media in the industry. Additionally, the new technology requires a greater degree of integration between heads and magnetic media which may lengthen our time of development of hard drives using this technology.
 
Furthermore, as we attempt to develop and implement new technologies, we may become more dependent on suppliers to ensure our access to components, technology and production equipment that accommodate the new technology. For example, advanced wafer and magnetic media manufacturing technologies have historically been developed for use in the semiconductor industry prior to the hard drive industry. However, successful implementation of the use of patterned magnetic media with hard drive magnetic media currently presents a significant technical challenge


26

facing the hard drive industry but not the semiconductor industry. Therefore, our suppliers may not be willing to dedicate adequate engineering resources to develop manufacturing equipment for patterned magnetic media prior to a need for the equipment in the semiconductor industry. We believe that if patterned magnetic media technology is not successfully implemented in the hard drive industry, then alternative storage technologies like solid-state storage may more rapidly overtake hard drives as the preferred storage solution for higher capacity storage needs. This result would put us at a competitive disadvantage and negatively impact our operating results.
 
 
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. 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, because increasing areal density has become more difficult in the hard drive industry, such increases may require increases in component costs, and other opportunities to reduce costs may not continue at historical rates. 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.
 
 
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. For example, serial interfaces normally go through cycles in which their maximum speeds double. We must effectively manage the transition of the features of our products to address these faster interface speeds in a timely manner in order to remain competitive and cost effective. If we fail to successfully and timely manage the transition to faster interface speeds, we may be at a competitive disadvantage to other companies that have successfully adapted their products in a timely manner and our operating results 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, or flash memory technology, have helped advance acceptance of “netbooks” in the PC market, and have successfully served digital entertainment markets for products such as digital cameras, MP3 players, USB flash drives and mobile phones that require lower storage capacity devices that cannot be economically manufactured using hard drive technology. Typically, storage needs for higher capacity and performance, with lower cost-per-gigabyte, have been better served by hard drives. However, advances in semiconductor technology have resulted in flash memory emerging as a technology that is competitive with hard drives for niche high performance needs in advanced digital computing markets such as enterprise servers and storage, in spite of the associated challenges in the attributes of cost, capacity and reliability. Additionally, solid-state storage is produced by large semiconductor companies who can sell their products at lower prices and operate their solid-state storage business unit at a loss while still remaining profitable overall in an attempt to gain market share. 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.

In attempting to remain competitive, we may need to increase our capital expenditures and expenses above our historical run-rate model in order to attempt to improve our existing technology and develop new technology. 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.
 
Our head manufacturing operations include a single wafer fabrication facility in California and a single slider fabrication and head gimbal assembly facility in Thailand, our magnetic media operations include three facilities in Malaysia, and our high volume hard drive manufacturing operations include facilities in Thailand and Malaysia, which subjects us to substantial risk of damage or loss if operations at any of these facilities are disrupted.
 
We design and manufacture a substantial portion of the heads and magnetic media required for the hard drives we manufacture. Approximately 80-90% of our requirement for heads is satisfied by wafers fabricated in our Fremont, California facility. Wafers are then sent to our Thailand facility for slider fabrication and wafer slicing and HGA assembly and testing. Additionally, we manufacture the majority of our magnetic media and substrates in three facilities in Malaysia. Our high volume hard drive manufacturing facilities are in Malaysia and Thailand, and the manufacturing facilities of many of our suppliers are also in Asia. A fire, flood, earthquake 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 supply of our heads or magnetic media and limit our ability to manufacture hard drives, which would result in a substantial loss of sales and revenue and a substantial harm to our operating results. Similarly, a localized health risk affecting our employees or the staff of our 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, which would result in substantial harm to our operating results.
 
 
To achieve consistent success with our customers, we must balance several key attributes such as time-to-market, time-to-volume, quality, cost, service, price and a broad product portfolio. Our operating results will be adversely affected if we fail to:
 
  •  maintain overall quality of products in new and established programs;
 
  •  produce sufficient quantities of products at the capacities our customers demand while managing the integration of new and established technologies;
 
  •  develop and qualify new products that have changes in overall specifications or features that our customers may require for their business needs;
 
  •  obtain commitments from our customers to qualify new products, redesigns of current products, or new components in our existing products;
 
  •  obtain customer qualification of these products on a timely basis by meeting all of our customers’ needs for performance, quality and features;
 
  •  maintain an adequate supply of components required to manufacture our products; or
 
  •  maintain the manufacturing capability to quickly change our product mix between different capacities, form factors and spin speeds in response to changes in customers’ product demands.
 
 
We are subject to risks associated with our foreign manufacturing operations and foreign marketing efforts, including:
 
  •  obtaining requisite U.S. and foreign governmental permits and approvals;


28


Table of Contents

 
  •  currency exchange rate fluctuations or restrictions;
 
  •  political instability and civil unrest, such as the recent protests and violence in Bangkok, Thailand;
 
  •  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 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.
 
 
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.
 
 
We ship the majority of our products to our various customers via air freight. The sudden unavailability of air cargo operations used to ship our products would impair our ability to deliver our products in a timely and efficient manner, which could adversely impact our operating results. We also ship a portion of our product via ocean freight, and events or conditions at shipping ports, such as labor difficulties or disputes, could also impact our operating results by impairing our ability to timely and efficiently deliver these products.
 
 
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.
 
 
While we expect our recent acquisition of SiliconSystems, Inc. to have only a nominal positive impact on our results in the near term, we believe that the acquisition may result in certain more significant future benefits, including technology efficiencies and synergies. However, we may encounter difficulties in the complicated process of integrating SiliconSystems’ business and technology into our existing operations. If we are not able to quickly and cost-effectively integrate SiliconSystems’ business and technology into our operations, our current operations may be disrupted and the future anticipated benefits of the acquisition may not be realized fully or at all. Consequently, our future results of operations may be adversely affected.

Our success depends upon the continued contributions of our key staff and skilled employees, many of whom would be extremely difficult to replace. Worldwide 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. This risk increases during periods of declining stock price, which may cause many of our key staff and skilled employees to lose much of the value of the equity compensation that they have received as an incentive to remain in our employ and work towards the success of our operations. 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 events such as the current global economic downturn, 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 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 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.
 
 
We may be subject to various state, federal and international laws and regulations governing the environment, including those restricting the presence of certain substances in electronic products and making producers of those products financially responsible for the collection, treatment, recycling and disposal of certain products. Such laws and regulations have been passed in several jurisdictions in which we operate. For example, the European Union (“EU”) has


30


Table of Contents

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. We will need to ensure that we comply with such laws and regulations as they are enacted, and that our component suppliers also timely comply with such laws and regulations. If we fail to timely comply with the legislation, our customers may refuse to purchase our products, 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 noncompliance 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.
 
 
Because we manufacture our products abroad, our operating costs are subject to fluctuations in foreign currency exchange rates. Further fluctuations in the exchange rate of the Thai Baht and of the Malaysian Ringgit may negatively impact our operating results. The Thai Baht is a free floating currency while the Malaysian Ringgit exchange rate policy is one of a managed float. We have attempted to manage the impact of foreign currency exchange rate changes by, among other things, entering into short-term, forward contracts. However, these contracts do not cover our full exposure and can be canceled by the issuer if currency controls are put in place. Currently, we hedge the Thai Baht, Malaysian Ringgit, Euro and British Pound Sterling with forward contracts.
 
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 which 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.
 
 
Some of our OEM customers have adopted a subcontractor model that requires us to contract directly with companies, such as ODMs, that provide manufacturing 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 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.

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. In addition, our quarterly projections and 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 components for our products;
 
  •  limited availability of components that we obtain from a single or a limited number of suppliers;
 
  •  competition and consolidation in the data storage industry;
 
  •  seasonal and other fluctuations in demand for PCs often due to technological advances; and
 
  •  availability and rates of transportation.
 
 
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; and
 
  •  liabilities for unrecognized tax benefits.
 
 
The market price of our common stock has been, and may continue to be, extremely volatile. Factors such as the following may significantly affect the market price of our common stock:
 
  •  actual or anticipated fluctuations in our operating results;
 
  •  announcements of technological innovations by us or our competitors which may decrease the volume and profitability of sales of our existing products and increase the risk of inventory obsolescence;
 
  •  new products introduced by us or our competitors;
 
  •  periods of severe pricing pressures due to oversupply or price erosion resulting from competitive pressures or industry consolidation;
 
  •  developments with respect to patents or proprietary rights;


32


Table of Contents

 
  •  conditions and trends in the hard drive, computer, data and content management, storage and communication industries;
 
  •  contraction in our operating results or growth rates that are lower than our previous high growth-rate periods;
 
  •  changes in financial estimates by securities analysts relating specifically to us or the hard drive industry in general; and
 
  •  macroeconomic conditions that affect the market generally.
 
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.
 
 
Our long-term investments consist of auction-rate securities totaling $18 million as of July 3, 2009. The negative conditions in the global credit markets have prevented some investors from liquidating their holdings of auction-rate securities because the amount of securities submitted for sale has exceeded the amount of purchase orders for such securities. If the credit market does not improve, auctions for our invested amounts may continue to fail. If an auction fails for securities in which we have invested, we may be unable to liquidate some or all of our auction-rate securities at par should we need or desire to access the funds invested in those securities. In the event we need or desire to access these funds, we will not be able to do so until a future auction on these investments is successful or a buyer is found outside the auction process. If a buyer is found but is unwilling to purchase the investments at par (or current carrying value), we may incur a loss beyond losses already recognized by us on these securities. For example, during the year ended July 3, 2009, the market values of some of the auction-rate securities we owned were impacted by the macroeconomic credit market conditions, and as a result, we recognized $10 million of other-than-temporary losses to mark the investments to estimated market value. Further, rating downgrades of the security issuer or the third-parties insuring such investments may require us to adjust the carrying value of these investments through an additional impairment charge.
 
 
The negative global economic conditions and volatile investment markets have caused us to hold more cash, cash equivalents and short-term investments 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 short-term investments 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.
 
 
Our most recent evaluation resulted in our conclusion that as of July 3, 2009, 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 or significant deficiency 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.
 
 
As we have previously disclosed, we are under examination of certain of our fiscal years by the U.S. Internal Revenue Service (the “IRS”). Separately, our French subsidiary is under examination by the French tax authorities. Although we


33


Table of Contents

believe our tax positions for the years under review are reasonable, the outcomes and timing of these audits are subject to significant uncertainty and could result in us having to pay amounts to the IRS or French tax authorities 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.

Item 7.   Management’s Discussion and Analysis of Financial Condition and Results of Operations
 
 
The following discussion and analysis contains forward-looking statements within the meaning of the federal securities laws. You are urged to carefully review our description and examples of forward-looking statements included earlier in this Annual Report on Form 10-K immediately prior to Part I, under the heading “Forward Looking Statements.” Forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in the forward-looking statements. You are urged to carefully review the disclosures we make concerning risks and other factors that may affect our business and operating results, including those made in Item 1A of this Annual Report on Form 10-K, as well as our other reports filed with the SEC. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this document. We do not intend, and undertake no obligation, to publish revised forward-looking statements to reflect events or circumstances after the date of this document or to reflect the occurrence of unanticipated events.
 
Our Company
 
We design, develop, manufacture and sell hard drives. A hard drive is a device that uses one or more rotating magnetic disks to store and allow fast access to data. Hard drives are key components of computers, including desktop and notebook computers (“PCs”), data storage subsystems and many consumer electronic (“CE”) devices.
 
We sell our products worldwide to original equipment manufacturers (“OEMs”) and original design manufacturers (“ODMs”) for use in computer systems, subsystems or CE devices, and to distributors, resellers and retailers. Our hard drives are used in desktop computers, notebook computers, and enterprise applications such as servers, workstations, network attached storage, storage area networks and video surveillance equipment. Additionally, our hard drives are used in CE applications such as digital video recorders (“DVRs”), and satellite and cable set-top boxes (“STBs”). We also sell our hard drives as stand-alone storage products and integrate them into finished enclosures, embedding application software and offering the products as WD®-branded external storage appliances for personal data backup and portable or expanded storage of digital music, photographs, video and other digital data.


37


Table of Contents

Hard drives provide non-volatile data storage, which means that the data remains present when power is no longer applied to the device. Our hard drives currently include 3.5-inch and 2.5-inch form factor drives, having capacities ranging from 40 gigabytes (“GB”) to 2 terabytes (“TB”), nominal rotation speeds up to 10,000 revolutions per minute (“RPM”), and offer interfaces including both Enhanced Integrated Drive Electronics (“EIDE”) and Serial Advanced Technology Attachment (“SATA”). We also embed our hard drives into WD®-branded external storage appliances using interfaces such as USB 2.0, external SATA, FireWiretm and Ethernet network connections with capacities of 160 GB up to 8 TB. In addition, we offer a family of hard drives specifically designed to consume substantially less power than standard drives, using our WD GreenPower Technologytm.
 
In the second quarter of 2009, we began to design, develop, manufacture and sell media players. A media player is a device that connects to a user’s television or home theater system and plays digital movies, music and photos from any of our WD®-branded external hard drives or other USB mass storage devices. We sell our media players worldwide to resellers and retailers under our WD® brand.
 
In the third quarter of 2009, we acquired SiliconSystems, Inc (“SiliconSystems”) and began to design, develop, manufacture and sell solid-state drives. A solid-state drive is a storage device that uses semiconductor, non-volatile media, rather than magnetic disks and magnetic heads, to store and allow fast access to data. We sell our solid-state drives worldwide to OEMs and distributors for use in the embedded systems market which includes network-communications, industrial, embedded-computing, medical, military, aerospace, media-appliance and data-streaming applications.
 
Results of Operations
 
On September 5, 2007, we completed our acquisition of Komag, Incorporated (“Komag”) and on March 27, 2009, we completed our acquisition of SiliconSystems. In accordance with U.S. generally accepted accounting principles (“U.S. GAAP”), operating results for Komag and SiliconSystems prior to the dates of their acquisitions are not included in our operating results, which therefore affects our discussion of changes in our revenues and expenses for the periods prior to the acquisitions as compared to the periods after the acquisitions.
 
 
In 2009, our net revenue decreased by 8% to $7.5 billion on hard drive shipments of 146 million units as compared to $8.1 billion and 133 million units, respectively, in 2008. In 2009, 62% of our hard drive revenue was derived from non-desktop sources including CE products, enterprise applications, notebook computers and retail sales as compared to 56% in 2008. Hard drive average selling price decreased to $51 in 2009 from $59 in 2008. Gross margin percentage decreased to 17.9% in 2009 from 21.5% in 2008. Operating income decreased by $487 million to $519 million in 2009, which included a $14 million in-process research and development charge related to the acquisition of SiliconSystems, $112 million of restructuring charges and an $18 million gain on the sale of assets from our media substrate manufacturing facility in Sarawak, Malaysia. Operating income was $1.0 billion in 2008, which included a $49 million in-process research and development charge related to the acquisition of Komag. As a percentage of net revenue, operating income was 7.0% in 2009 compared to 12.4% in 2008. Net income in 2009 was $470 million, or $2.08 per diluted share, compared to $867 million, or $3.84 per diluted share, in 2008.
 
During December 2008, our second fiscal quarter, we announced a restructuring plan to realign our cost structure as a result of a softer demand environment. This plan was completed during our third and fourth fiscal quarters of 2009. This resulted in the closure of one of our hard drive manufacturing facilities in Thailand, the disposal of our media substrate manufacturing facility in Sarawak, Malaysia, and headcount reductions throughout the world of approximately 3,300 people. Restructuring costs totaled $112 million and consisted of $81 million of asset 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 approximately $31 million. During our fourth fiscal quarter, we sold our media substrate manufacturing facility, and related assets, in Sarawak, Malaysia for net proceeds of approximately $29 million, resulting in a gain of $18 million. The closure and disposal of our manufacturing facilities was to realign our manufacturing capacity with our expectations regarding demand at that time. During our fourth fiscal quarter, we experienced a much stronger demand than originally anticipated. We expect continuing sequential growth in our first quarter of fiscal 2010. As a result, in our first quarter of fiscal 2010, we reopened the hard drive manufacturing facility in Thailand that we previously closed as part of our restructuring plan.

We also completed our acquisition of SiliconSystems resulting in a total acquisition cost of $66 million, consisting of $65 million in cash paid to SiliconSystems shareholders and $1 million of other direct acquisition costs.

Net Revenue.  Net revenue was $7.5 billion for 2009, a decrease of 8% from 2008. Total unit shipments of hard drives increased to 146 million as compared to 133 million for the prior year. The decrease in revenue primarily resulted from a decline in our ASPs which reflects a more competitive pricing environment, particularly in the notebook and branded markets. The decline in our ASPs was partially offset by an increase in unit shipments of 2.5-inch drives. We shipped 56 million 2.5-inch drives in 2009 as compared to 37 million units in 2008. The increase in 2.5-inch 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 and by channel 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 increases in sales of mobile hard drives to OEMs.
 
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 2009, these programs represented 11% of gross revenues compared to 10% in 2008. 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 2009 was $1.3 billion, a decrease of $402 million, or 23% over the prior year. Gross margin percentage decreased to 17.9% in 2009 from 21.5% in 2008. This decrease is due to a more competitive pricing environment primarily resulting from an increase in product offerings in the mobile and branded markets.
 
Operating Expenses.  Total research and development (“R&D”) expense and selling, general and administrative (“SG&A”) expense increased to 9.5% of net revenue in 2009 compared to 8.5% in 2008. R&D expense was $509 million in 2009, an increase of $45 million, or 10% over the prior year. This increase in R&D expense includes $76 million relating to product development to support new programs offset by a $31 million decrease in variable incentive compensation. As a percentage of net revenue, R&D expense increased to 6.8% in 2009 compared to 5.7% in 2008 primarily due to continued investment in product development. SG&A expense was $201 million in 2009, a decrease of $19 million, or 8.6%, as compared to 2008. This decrease in SG&A expense primarily resulted from a $19 million decrease in variable incentive compensation and a $6 million insurance recovery, offset by a $6 million net increase in the expansion of our sales and marketing presence into new regions. SG&A expense was 2.7% as a percentage of revenue in both 2009 and 2008.
 
During 2009, we recorded a $14 million in-process research and development charge related to the acquisition of SiliconSystems. During 2008, we recorded a $49 million in-process research and development charge related to the acquisition of Komag. These charges relate 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 quality 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 assets from our media substrate manufacturing facility in Sarawak, Malaysia.
 
Other Income (Expense).  Net interest and other expense was $18 million in 2009 compared to $25 million in 2008. This change was primarily due to a decrease in the variable interest rate on our debt and a $3 million decrease in losses on our auction-rate securities.
 
Income Tax Provision.  Income tax expense was $31 million in 2009 compared to $114 million in 2008. Tax expense as a percentage of income before taxes was 6% in 2009 compared to 12% for 2008. Differences between the effective tax rates and the U.S. Federal statutory rate are primarily due to tax holidays and incentive programs and the current year generation of income tax credits. We have tax holidays in Malaysia and Thailand that expire at various times through 2022. In 2009, income tax expense includes 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. In 2008, tax expense included net charges of $60 million for taxes incurred upon the license of certain intellectual property to a foreign subsidiary in our first fiscal quarter.
 
We recognized a $29 million increase in the liability for unrecognized tax benefits during 2009. As of July 3, 2009, we had approximately $136 million of unrecognized tax benefits which, if recognized, would decrease the effective tax rate in subsequent years.
 
 
Net Revenue.  Net revenue was $8.1 billion for 2008, an increase of 48% from 2007. Total unit shipments increased to 133 million as compared to 97 million for the prior year. This unit increase resulted from an increase in higher overall

Table of Contents

demand for hard drives and our continuing diversification into non-desktop markets, including mobile, consumer electronics, enterprise and branded products. For example, we shipped 37 million 2.5 inch drives to the mobile and branded markets in 2008 as compared to 12 million units in 2007. Additionally, we shipped 15 million units to the DVR market in 2008 as compared to 10 million units in 2007. ASPs increased to $59 due to an improved mix of revenues by market category, improved product mix and more favorable demand/supply conditions. Changes in revenue by geography generally reflect normal fluctuations in market demand and competitive dynamics as well as an increase in mobile drives sold to Asia. Changes in revenue by channel are a result of increases in sales of mobile hard drives to OEMs and an increase in sales of branded products due to the growing worldwide acceptance of our My Passport® and My Book® external digital storage appliances.
 
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 the year ended June 27, 2008, these programs represented 10% in 2008 compared to 7% in 2007. 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 2008 was $1.7 billion, an increase of $839 million, or 93% over 2007. Gross margin percentage increased to 21.5% in 2008 from 16.5% in 2007. The factors contributing to this increase were an improved mix of revenues by market category, improved product mix and more favorable demand/supply conditions. Our manufacturing throughput and costs also improved through operational efficiencies, higher utilization and a higher mix of products based on newer, more cost-effective technologies and the contribution of media operations.
 
Operating Expenses.  Total operating expenses, consisting of research and development (“R&D”) and selling, general and administrative (“SG&A”), decreased to 8.5% of net revenue in 2008 compared to 8.9% in 2007. R&D expense was $464 million in 2008, an increase of $158 million, or 52% over the prior year. This increase in R&D expense includes $75 million relating to the acquired media operations, $52 million related to product development to support new programs and $31 million in incentive and equity compensation. As a percentage of net revenue, R&D expense remained consistent at 5.7% in 2008 compared to 5.6% in 2007. SG&A expense was $220 million in 2008, an increase of $41 million, or 23%, as compared to 2007. This increase in SG&A expense includes $28 million for the expansion of sales and marketing to support new products and $13 million in higher incentive and equity compensation. As a percentage of net revenue, SG&A expense decreased to 2.7% in 2008 from 3.3% in 2007 primarily due to an increase in net revenue in 2008 compared to 2007.
 
During 2008, we recorded a $49 million charge to operating expense related to an in-process research and development project acquired from Komag involving technology for higher recording densities on advanced perpendicular recording magnetic media. As these advanced products were not ready for commercial production and had no alternative future use, the fair value of the development effort did not qualify for capitalization and was immediately expensed.
 
Other Income (Expense).  Net interest and other expense was $25 million in 2008 compared to net interest and other income of $28 million in 2007. This decrease is a result of higher debt balances and realized and recognized losses on investments of $13 million.
 
Income Tax Provision.  Income tax expense was $114 million in 2008 compared to an income tax benefit of $121 million in 2007. Tax provision as a percentage of income before taxes was 12% in 2008 compared to tax benefit as a percentage of income of 27% for 2007. Differences between the effective tax rates and the U.S. Federal statutory rate are primarily due to tax holidays and incentive programs and the current year generation of income tax credits. We have tax holidays in Malaysia and Thailand that expire at various times through 2022. In 2008, income tax expense also includes net charges of $60 million for taxes incurred upon the license of certain intellectual property to a foreign subsidiary in our first fiscal quarter. In 2007, the tax provision was impacted by a favorable adjustment to the company’s valuation allowance for deferred tax assets of $126 million. In the fourth quarter of 2007, we reversed the remaining valuation allowance for our deferred tax assets based upon a determination that it was more likely than not that our deferred tax assets will be realized. The realization of the deferred tax assets is primarily dependent on our ability to generate sufficient earnings in certain jurisdictions in future years. The amount of deferred tax assets considered realizable may increase or decrease in subsequent periods based on fluctuating industry or company conditions.

We adopted the provisions of FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of FASB Statement No. 109” (“FIN 48”), as of June 30, 2007. As a result of the implementation of FIN 48, we recognized no adjustment in the net liability for unrecognized tax benefits. The total amount of gross unrecognized tax benefits as of the date of adoption of FIN 48 was $58 million, all of which would affect our effective tax rate if realized. During the year ended June 27, 2008, we recognized a $17 million increase in the liability for unrecognized tax benefits and recorded $32 million of liabilities for unrecognized tax benefits related to Komag. As of June 27, 2008, we had approximately $107 million of unrecognized tax benefits which included the $32 million of gross unrecognized tax benefits related to Komag.
 
Liquidity and Capital Resources
 
We ended 2009 with total cash and cash equivalents of $1.8 billion, an increase of $690 million from June 27, 2008. The following table summarizes the results of our statements of cash flows for the three years ended July 3, 2009:

Net increase in cash and cash equivalents
  $ 690     $ 404     $ 149  
                         
 
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 needs through the foreseeable future. Our ability to sustain our working capital position is subject to a number of risks that are discussed in Item 1A of this Annual Report on Form 10-K.
 
 
Net cash provided by operating activities during 2009 was $1.3 billion as compared to $1.4 billion for 2008 and $618 million for 2007. 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 changes in working capital was $198 million for 2009 as compared to $22 million for 2008 and $78 million used to fund working capital for 2007.
 
Our working capital requirements primarily depend upon the effective management of our cash conversion cycle, which measures how quickly we can convert our products into cash through sales. The following table summarizes the cash conversion cycle for the three years ended 2009:
 
                         
    Years Ended  
    July 3,
    June 27,

For the year ended July 3, 2009, our days sales outstanding (“DSOs”) increased by 1 day, days in inventory (“DIOs”) decreased by 1 day, and days payables outstanding remained consistent with 2008.
 
From time to time, we modify the timing of payments to our vendors. We make these 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 or by granting to or receiving from our vendors payment term accommodations.
 
 
Net cash used in investing activities for 2009 was $551 million as compared to $1.3 billion for 2008 and $383 million for 2007. During 2009, cash used in investing activities primarily consisted of $519 million for capital expenditures and $63 million for the acquisition of SiliconSystems, net of cash acquired. During 2008, cash used in investing activities consisted of $927 million for the acquisition of Komag, net of cash acquired, and $615 million for capital expenditures, partially offset by net cash provided by investments of $221 million. The decrease in capital expenditures in 2009 compared to 2008 was primarily the result of the expected reduction in market demand due to the macroeconomic conditions. Capital expenditures in 2009 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 2010, we expect capital expenditures to be approximately $600 million and depreciation and amortization to be approximately $530 million.
 
Our cash equivalents are invested primarily in readily accessible, AAA rated institutional money market funds which are invested in U.S. Treasury securities, U.S. Treasury bills and U.S. Government agency securities. We also have auction-rate securities that are classified as long-term investments as they are expected to be held until secondary markets become available. These investments are currently accounted for as available-for-sale securities and recorded at fair value within other non-current assets in the consolidated balance sheet. The estimated market values of these investments are subject to fluctuation. The carrying value of our investments in auction-rate securities was reduced from $28 million as of June 27, 2008 to $18 million as of July 3, 2009, as a result of the recognition of $10 million in other-than-temporary losses that were recorded through earnings.
 
 
Net cash used by financing activities for 2009 was $64 million as compared to net cash provided by financing activities for 2008 of $326 million. Net cash used in financing activities was $86 million for 2007. The net cash provided by financing activities in 2009 consisted of $28 million provided by the issuance of stock under employee plans, offset by $36 million used to repurchase our common stock, a $24 million decrease in excess tax benefits from employee stock plans, $5 million in tax withholding obligations paid in connection with the vesting of stock awards under employee stock plans, and $27 million used to repay long-term debt. The net cash provided by financing activities in 2008 consisted of $500 million in net proceeds from debt, $89 million provided by an increase in excess tax benefits from employee stock plans, $65 million provided by the issuance of stock under employee stock plans, offset by a $250 million repayment of convertible debentures assumed in the acquisition of Komag, $60 million used to repurchase our common stock, $13 million used to repay other long-term debt and $5 million in tax withholding obligations paid in connection with the vesting of stock awards under employee stock plans. The net cash used in financing activities in 2007 consisted of $73 million used for repurchases of our common stock, $43 million used for repayments of long-term debt, $9 million in tax withholding obligations paid in connection with the vesting of stock awards under employee stock plans, offset by $39 million provided by the issuance of stock under employee plans.
 
 
Other than facility and equipment 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.

In February 2008, Western Digital Technologies, Inc. (“WDTI”), a wholly-owned subsidiary of the Company, entered into a five-year Credit Agreement (“Credit Facility”) that provides for a $750 million unsecured loan consisting of a $500 million term loan facility and a $250 million revolving credit facility. The revolving credit facility includes borrowing capacity available for letters of credit and for short-term borrowings referred to as swingline. In addition, WDTI may elect to expand the Credit Facility by up to $250 million if existing or new lenders provide additional term or revolving commitments. The $500 million term loan had a variable interest rate of 1.63% as of July 3, 2009 and requires sixteen quarterly principal payments, that began in June 2009, of approximately $19 million, $25 million, $31 million and $50 million per quarter for each four quarter increment. The Credit 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 Credit 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 3, 2009, WDTI had $250 million available for future borrowings on the revolving credit facility and was in compliance with all covenants.
 
 
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.
 
 
We purchase short-term, forward exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, 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 our current forward exchange contract commitments.
 
 
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 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.
 
 
Our Board of Directors previously authorized us to repurchase $750 million of our common stock in open market transactions under a program through March 31, 2013. Since the inception of this stock repurchase program in 2005, through July 3, 2009, we have repurchased 18 million shares for a total cost of $284 million (including commissions). We expect stock repurchases to be funded principally by operating cash flows. We may continue to repurchase our stock as we deem appropriate and market conditions allow.
 
Critical Accounting Policies and Estimates
 
We have prepared the accompanying consolidated financial statements in conformity with accounting principles generally accepted in the U.S. (“U.S. GAAP”). The preparation of the financial statements requires the use of judgment 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.
 
 
In accordance with standard industry practice, we provide resellers with limited price protection for inventories held by resellers at the time of published list price reductions and other sales incentive programs. In accordance with current accounting standards, we recognize revenue upon delivery to OEMs, ODMs and resellers and record a reduction of revenue for estimated price protection and other programs in effect until the resellers sell such inventory to their customers. We base 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 our expectations, our operating results could be 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. We apply the provisions of Emerging Issues Task Force No. 01-9, “Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor’s Products)” and such sales incentive and marketing programs 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 2007, 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 increase 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 0.2% of quarterly gross revenue since 2007.
 
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 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 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 negatively affect operating results.
 
 
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 we exercise 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. 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. Also, during a period of declining revenue, the percentage of warranty utilization to revenue may increase. 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. For a summary of historical changes in estimates related to pre-existing warranty provisions, refer to Part II, Item 8, Note 4 of the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K.
 
 
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 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 first-in, first-out 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 negatively affect operating results.

We apply SFAS No. 5, “Accounting for Contingencies,” to determine when and how much to accrue for and disclose related to legal and other contingencies. Accordingly, we disclose material contingencies deemed to be reasonably possible and accrue loss contingencies when, in consultation with our legal advisors, we conclude that a loss is probable and reasonably estimable (Refer to Part II, Item 8, Note 5 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K). 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.
 
 
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 (“NOL”) 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 quarter 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 the two-step process prescribed in Financial Accounting Standards Board (“FASB”) Interpretation No. 48, “Accounting for Uncertainty in Income Taxes- an interpretation of FASB Statement No. 109.” 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 benefit 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.
 
 
We account for all stock-based compensation in accordance with the fair value recognition provisions of SFAS No. 123(R), “Share-Based Payment” (“SFAS 123(R)”). Under these provisions, 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”) shares 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. Under SFAS 123(R), 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 impacted.
 
 
In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS 157”). SFAS 157 establishes a framework for measuring fair value under U.S. GAAP and expands disclosures about fair value measurement. In February 2008, FASB issued FASB Staff Position 157-2, “Effective Date of FASB Statement 157” (“FSP 157-2”), which delays the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis, until fiscal years beginning after November 15, 2008 and interim periods within those years, which for us is the first quarter of fiscal 2010. The partial adoption of SFAS 157 for financial assets and financial liabilities in our first quarter of fiscal 2009 did not have a material impact on our consolidated financial statements. We are currently evaluating the impact the adoption of SFAS 157 will have on the non-financial assets and non-financial liabilities in our consolidated financial statements.
 
In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits entities to choose to measure many financial assets and financial liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings.

Table of Contents

We chose not to elect the fair value option for eligible items, and accordingly, the adoption of SFAS 159 in the first quarter of fiscal 2009 had no impact on our consolidated financial statements.
 
In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations” (“SFAS 141(R)”). SFAS 141(R) establishes principles and requirements for how the acquirer of a business recognizes and measures in its financial statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree. SFAS 141(R) also provides guidance for recognizing and measuring the goodwill acquired in the business combination or a gain from a bargain purchase and determines what information to disclose to enable users of financial statements to evaluate the nature and financial effects of the business combination. SFAS 141(R) applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008, which for us is the first quarter of fiscal 2010. SFAS 141(R) will impact the Company’s consolidated financial statements for business combinations with an acquisition date on or after adoption in the first quarter of fiscal 2010.
 
In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities-an amendment of FASB Statement No. 133” (“SFAS 161”). SFAS 161 updates guidance regarding disclosure requirements for derivative instruments and hedging activities. The adoption of SFAS 161 in our third quarter of fiscal 2009 did not have a material impact on our consolidated financial statements.
 
In April 2008, the FASB issued FSP FAS 142-3, “Determination of the Useful Life of Intangible Assets” (“FSP FAS 142-3”), which amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under FASB Statement No. 142 “Goodwill and Other Intangible Assets”. FSP FAS 142-3 is effective for fiscal years beginning on or after December 15, 2008, which for us is the first quarter of fiscal 2010. We are currently evaluating the impact the adoption of FSP FAS 142-3 will have on our consolidated financial statements.
 
In April 2009, the FASB issued FSP FAS 107-1 and ABP 28-1, “Interim Disclosures about Fair Value of Financial Instruments” (“FSP FAS 107-1 and ABP 28-1”), which amends SFAS No. 107, “Disclosures about Fair Value of Financial Instruments”, and ABP Opinion No. 28, “Interim Financial Reporting”, to require disclosures about fair value of financial instruments in interim and annual reporting periods. FSP FAS 107-1 and ABP 28-1 is effective for interim reporting periods ending after June 15, 2009, which for us is the first quarter of fiscal 2010.
 
In April 2009, the FASB issued FSP FAS 115-2 and FAS 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments” (“FSP FAS 115-2 and FAS 124-2”), which amends the other-than-temporary impairment guidance in U.S. GAAP for debt securities to make the guidance more operational and to modify the presentation and disclosure of other-than-temporary impairments on debt and equity securities in the financial statements. The adoption of FSP FAS 115-2 and FAS 124-2 in the fourth quarter of fiscal 2009 did not have a material impact on our consolidated financial statements.
 
In May 2009, the FASB issued SFAS 165, “Subsequent Events” (“SFAS 165”) which establishes accounting and disclosure requirements for events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. SFAS 165 requires disclosure of the date through which the Company has evaluated subsequent events for recognition or disclosure. SFAS 165 also requires events that provide additional evidence about conditions that existed at the date of the balance sheet and the related estimates to be recognized in the financial statements. Events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after the balance sheet date but before the financial statements are issued or available to be issued should not be recognized, but should be disclosed if material. The adoption of SFAS 165 in the fourth quarter of fiscal 2009 did not have a material impact on our consolidated financial statements.
 
Item 7A.   Quantitative and Qualitative Disclosures About Market 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, 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 short-term foreign exchange contracts for trading purposes. Currently, we focus on hedging our foreign currency risk related to the Thai Baht, Malaysian Ringgit, Euro and the British Pound Sterling. Malaysian Ringgit contracts are designated as cash flow hedges. Euro and British Pound Sterling contracts are designated as fair value hedges. Thai Baht contracts are designated as both cash flow and fair value hedges. See Part II, Item 8, Note 1 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.
 
As of July 3, 2009, we had outstanding the following purchased foreign exchange contracts (in millions, except weighted average contract rate):

In 2009, 2008 and 2007, total net realized transaction and forward exchange contract currency gains and losses were not material to our consolidated financial statements.
 
 
 
Borrowings under the Credit 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 margin for revolving loan borrowings under the revolving credit facility ranges from 0.8% to 1.125% 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 Credit 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 increases, our interest payments could also increase. A one percent increase in the variable rate of interest on the Credit Facility would increase interest expense by approximately $5 million annually.
 
 
Our long-term investments consist of auction-rate securities totaling $18 million as of July 3, 2009. The negative conditions in the global credit markets have prevented us from liquidating some of our holdings of auction rate securities because the amount of securities submitted for sale has exceeded the amount of purchase orders for such securities. If the credit markets do not improve, auctions for our invested amounts may continue to fail. If this occurs, we may be unable to liquidate some or all of our auction-rate securities at par should we need or desire to access the funds invested in those securities prior to maturity of the underlying assets. In the event we need or desire to access these funds, we will not be able to do so until a future auction on these investments is successful or a buyer is found outside the auction process. If a buyer is found but is unwilling to purchase the investments at par, we may incur a loss. The market values of some of the auction-rate securities we owned were impacted by the macroeconomic credit market conditions. Rating downgrades of the security issuer or the third-parties insuring such investments may require us to adjust the carrying value of these investments through an impairment charge. Based on our ability to access our cash, cash equivalents and cash generated from operations, we do not anticipate these investments will affect our ability to execute our current business plan.

Western Digital Corporation:
 
We have audited the accompanying consolidated balance sheets of Western Digital Corporation and subsidiaries as of July 3, 2009 and June 27, 2008, 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 3, 2009. 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.
 
In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Western Digital Corporation and subsidiaries as of July 3, 2009 and June 27, 2008, and the results of their operations and their cash flows for each of the years in the three-year period ended July 3, 2009, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
 
We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Western Digital Corporation and subsidiaries’ internal control over financial reporting as of July 3, 2009, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated August 13, 2009 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

Western Digital Corporation:
 
We have audited Western Digital Corporation and subsidiaries’ internal control over financial reporting as of July 3, 2009, 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 and subsidiaries maintained, in all material respects, effective internal control over financial reporting as of July 3, 2009, 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 3, 2009 and June 27, 2008, 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 3, 2009, and the related financial statement schedule, and our report dated August 13, 2009 expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.

WESTERN DIGITAL CORPORATION
 
 
Note 1.   Organization and Summary of Significant Accounting Policies
 
Western Digital Corporation (the “Company” or “Western Digital” or “WD”) designs, develops, manufactures and sells hard drives. A hard drive is a device that stores data on one or more rotating magnetic media to allow fast access to data. The Company sells its products worldwide to original equipment manufacturers and original design manufacturers for use in computer systems, subsystems or CE devices, and to distributors, resellers and retailers. The Company’s hard drives are used in desktop computers, notebook computers, external storage appliances, enterprise applications such as servers, workstations, network attached storage, storage area networks and video surveillance equipment and in consumer electronics products such as digital video recorders and satellite and cable set-top boxes.
 
The Company also designs, develops, manufactures and sells solid-state drives and media players. A solid-state drive is a storage device that uses semiconductor, non-volatile media, rather than magnetic disks and magnetic heads, to store and allow fast access to data. The Company sells its solid-state drives worldwide to OEMs and distributors for use in the embedded systems market which includes network-communications, industrial, embedded-computing, medical, military, aerospace, media-appliance and data-streaming applications. A media player is a device that connects to a user’s television or home theater system and plays digital movies, music and photos from any of the Company’s WD®-branded external hard drives or other USB mass storage devices. The Company sells its media players worldwide to resellers and retailers under the WD® brand.
 
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 2009 fiscal year which ended on July 3, 2009 consisted of 53 weeks. The 2008 and 2007 fiscal years, which ended on June 27, 2008 and June 29, 2007, respectively, consisted of 52 weeks each.
 
 
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 March 27, 2009, the Company completed its acquisition of SiliconSystems, Inc. (“SiliconSystems”). On September 5, 2007, the Company completed its acquisition of Komag, Inc. (“Komag”). The acquisitions are further described in Note 14 below. The results of operations of SiliconSystems and Komag since the dates of their acquisitions are included in the consolidated financial statements. The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, including SiliconSystems and Komag. All significant inter-company accounts and transactions have been eliminated in consolidation.
 
 
The Company’s cash equivalents represent highly liquid investments in money market funds, U.S. Treasury securities, and U.S. Government agency securities with original maturities of three months or less.
 
 
The Company’s investments consist primarily of auction-rate securities, which are primarily investments in insurance products with original maturities greater than three months. The Company has classified these investments as


57


Table of Contents

 
WESTERN DIGITAL CORPORATION
 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
“available for sale” securities under Statement of Financial Accounting Standards (“SFAS”) No. 115 “Accounting for Certain Investments in Debt and Equity Securities” and they are carried at fair value.
 
 
The carrying amounts of cash and 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.
 
 
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 3, 2009 and June 27, 2008, the Company had reserves for potential credit losses of $14 million and $8 million, respectively, and net accounts receivable of $926 million and $1.0 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.
 
 
The Company values inventory at the lower of cost (first-in, first out and weighted average methods) or net realizable value. The first-in, first-out 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 first-in, first-out method. As of July 3, 2009 and June 27, 2008, 82% and 78%, respectively, 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 our products, which may require a write down of inventory that could negatively affect operating results.
 
 
The cost of property and equipment is depreciated over the estimated useful lives of the respective assets. The Company’s buildings are being depreciated over periods ranging from fifteen to thirty years. The majority of the Company’s equipment is being 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.

In accordance with SFAS No. 141, “Business Combinations” (“SFAS 141”), 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. In accordance with SFAS No. 142, “Goodwill and Other Intangible Assets”, 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 2009.
 
Other intangible assets consist of technology acquired in business combinations. Acquired intangibles are amortized on a straight-line basis over their respective estimated useful lives. In accordance with SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets” (“SFAS 144”), long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. The Company recorded impairments to certain long-lived assets during 2009. See Note 13.
 
 
The Company recognizes revenue in accordance with SEC Staff Accounting Bulletin (“SAB”) No. 104, “Revenue Recognition in Financial Statements” (“SAB No. 104”). Under SAB No. 104, 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 negatively affect operating results.
 
In accordance with standard industry practice, the Company provides resellers with limited price protection for inventories held by resellers at the time of published list price reductions and other sales incentive programs. In accordance with current accounting standards, the Company recognizes revenue upon delivery to OEMs, ODMs and resellers and records a reduction of revenue for estimated price protection and other programs in effect until the resellers sell such inventory to their customers. 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 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. The Company applies the provisions of Emerging Issues Task Force No. 01-9, “Accounting for Consideration Given by a Vendor to a Customer (Including a Reseller of the Vendor’s Products),” and such 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 affect operating results.
 
 
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 with estimates and assists in exercising


59

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
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. 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. Also, during a period of declining revenue, the percentage of warranty utilization to revenue may increase. 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.
 
 
Advertising costs are expensed as incurred. Selling, general and administrative expenses of the Company include advertising costs of $5 million, $3 million and $5 million in 2009, 2008 and 2007, respectively.
 
 
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 the two-step process prescribed in FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes — an interpretation of Financial Accounting Standards Board (“FASB”) Statement No. 109” (“FIN 48”). 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 the provision for income taxes. The actual liability for unrealized tax benefit in any such contingency 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.
 
 
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 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 our Employee Stock Purchase Plan (“ESPP”) and restricted stock and stock unit awards.

* For purposes of computing diluted income per common share, common share equivalents with an exercise price that exceeded the average fair market value of common stock for the period are considered anti-dilutive and have been excluded from the calculation.
 
 
The Company accounts for all stock-based compensation in accordance with the fair value recognition provisions in SFAS No. 123(R). Under the fair value recognition provisions of SFAS 123(R), 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 models require the input of highly subjective assumptions. Under SFAS 123(R), 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 impacted.
 
 
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.
 
 
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, forward 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. The contracts have maturity dates that do not exceed 12 months. The Company does not purchase short-term forward exchange contracts for trading purposes.
 
The Company applies the provisions of SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities” (“SFAS 133”), as amended, which establishes accounting and reporting standards for derivative instruments embedded in other contracts and for hedging activities. The Company had outstanding forward exchange contracts with

commercial banks for Thai Baht, Malaysian Ringgit, British Pound Sterling and Euro with values of $583 million and $1.3 billion at July 3, 2009 and June 27, 2008, respectively. Malaysian Ringgit contracts are designated as cash flow hedges. Euro and British Pound Sterling contracts are designated as fair value hedges. Thai Baht contracts are designated as either cash flow or fair value hedges.
 
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 revenues. 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 has determined that all of its cash flow hedging instruments for all years presented were effective as defined under SFAS 133.
 
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 as defined under SFAS 133. Changes in fair value on these contracts were not material to the consolidated financial statements for all years presented.
 
 
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 which are consistent throughout the periods presented. However, actual results could differ from these estimates.
 
 
Certain prior year amounts have been reclassified to conform to the current year presentation.
 
 
The Company evaluated subsequent events through August 13, 2009, the date these financial statements were issued, and there were no material subsequent events that required recognition or additional disclosure in these financial statements.
 
 
In September 2006, FASB issued SFAS 157, “Fair Value Measurement” (“SFAS 157”), which establishes a framework for measuring fair value under U.S. GAAP and expands disclosures about fair value measurement. In February 2008, FASB issued FASB Staff Position 157-2, “Effective Date of FASB Statement 157” (“FSP 157-2”), which delayed the effective date of SFAS 157 for all nonfinancial assets and nonfinancial liabilities, except those that are recognized or disclosed at fair value in the financial statements on a recurring basis, until fiscal years beginning after November 15, 2008 and interim periods within those years, which for the Company is the first quarter of fiscal 2010. The partial adoption of SFAS 157 for financial assets and financial liabilities in the Company’s first quarter of fiscal 2009 did not have a material impact on its consolidated financial statements. See Note 10. The Company is currently evaluating the impact the adoption of SFAS 157 will have on the non-financial assets and non-financial liabilities in its consolidated financial statements.
 
In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities” (“SFAS 159”). SFAS 159 permits entities to choose to measure many financial assets and financial liabilities at fair value. Unrealized gains and losses on items for which the fair value option has been elected are reported in earnings. The Company chose not to elect the fair value option for eligible items, and accordingly, the adoption of SFAS 159 in the first quarter of fiscal 2009 had no impact on the Company’s consolidated financial statements.
 
In December 2007, the FASB issued SFAS No. 141(R), “Business Combinations” (“SFAS 141(R)”). SFAS 141(R) establishes principles and requirements for how the acquirer of a business recognizes and measures in its financial

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)
 
statements the identifiable assets acquired, the liabilities assumed, and any noncontrolling interest in the acquiree. SFAS 141(R) also provides guidance for recognizing and measuring the goodwill acquired in the business combination or a gain from a bargain purchase and determines what information to disclose to enable users of financial statements to evaluate the nature and financial effects of the business combination. SFAS 141(R) applies prospectively to business combinations for which the acquisition date is on or after the beginning of the first annual reporting period beginning on or after December 15, 2008, which for the Company is the first quarter of fiscal 2010. SFAS 141(R) will impact the Company’s consolidated financial statements for business combinations with an acquisition date on or after adoption in the first quarter of fiscal 2010.
 
In March 2008, the FASB issued SFAS No. 161, “Disclosures about Derivative Instruments and Hedging Activities-an amendment of FASB Statement No. 133” (“SFAS 161”). SFAS 161 updates guidance regarding disclosure requirements for derivative instruments and hedging activities. The adoption of SFAS 161 in the Company’s third quarter of fiscal 2009 did not have a material impact on its consolidated financial statements.
 
In April 2008, the FASB issued FSP FAS 142-3, “Determination of the Useful Life of Intangible Assets” (“FSP FAS 142-3”), which amends the factors that should be considered in developing renewal or extension assumptions used to determine the useful life of a recognized intangible asset under FASB Statement No. 142 “Goodwill and Other Intangible Assets”. FSP FAS 142-3 is effective for fiscal years beginning on or after December 15, 2008, which for the Company is the first quarter of fiscal year 2010. The Company is currently evaluating the impact the adoption of FSP FAS 142-3 will have on its consolidated financial statements.
 
In April 2009, the FASB issued FSP FAS 107-1 and ABP 28-1, “Interim Disclosures about Fair Value of Financial Instruments” (“FSP FAS 107-1 and ABP 28-1”), which amends SFAS No. 107, “Disclosures about Fair Value of Financial Instruments”, and ABP Opinion No. 28, “Interim Financial Reporting”, to require disclosures about fair value of financial instruments in interim and annual reporting periods. FSP FAS 107-1 and ABP 28-1 is effective for interim reporting periods ending after June 15, 2009, which for the Company is the first quarter of fiscal 2010.
 
In April 2009, the FASB issued FSP FAS 115-2 and FAS 124-2, “Recognition and Presentation of Other-Than-Temporary Impairments” (“FSP FAS 115-2 and FAS 124-2”), which amends the other-than-temporary impairment guidance in U.S. GAAP for debt securities to make the guidance more operational and to modify the presentation and disclosure of other-than-temporary impairments on debt and equity securities in the financial statements. The adoption of FSP FAS 115-2 and FAS 124-2 in the Company’s fourth quarter of fiscal 2009 did not have a material impact on its consolidated financial statements.
 
In May 2009, the FASB issued SFAS 165, “Subsequent Events” (“SFAS 165”), which establishes accounting and disclosure requirements for events or transactions that occur after the balance sheet date but before financial statements are issued or are available to be issued. SFAS 165 requires disclosure of the date through which the Company has evaluated subsequent events for recognition or disclosure. SFAS 165 also requires events that provide additional evidence about conditions that existed at the date of the balance sheet and the related estimates to be recognized in the financial statements. Events that provide evidence about conditions that did not exist at the date of the balance sheet but arose after the balance sheet date but before the financial statements are issued or available to be issued should not be recognized, but should be disclosed if material. The adoption of SFAS 165 in the Company’s fourth quarter of fiscal 2009 did not have a material impact 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 (“Credit Facility”) that provides for a $750 million unsecured loan consisting of a $500 million term loan facility and a $250 million revolving credit facility. The revolving credit facility includes borrowing capacity available for letters of credit and for short-term borrowings referred to as swingline. In addition, WDTI may elect to expand the Credit Facility by up to $250 million if existing or new lenders provide additional term or revolving commitments. The $500 million term loan had a variable interest rate of 1.63% as of July 3, 2009 and requires sixteen quarterly principal payments, that began in June 2009, of approximately $19 million, $25 million, $31 million and $50 million per quarter for each four quarter increment. The Credit 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.

Note 5.   Legal Proceedings
 
In the normal course of business, the Company is subject to legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these 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 matters or the specified matters below, 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 legal proceedings, lawsuits and other claims could differ materially from those projected.
