PART I

Item 1. Business

General

We are a leading developer, manufacturer and provider of data storage solutions that enable consumers, businesses, governments and other organizations to create, manage, experience and preserve digital content. Our product portfolio includes hard disk drives (“HDDs”) and solid-state drives ("SSDs"). HDDs are our principal products and are today’s primary storage medium for digital content, with the use of solid-state storage products growing rapidly. Our products are marketed under the HGST, WD and G-Technology brand names. Over the last 10 years, we have achieved strong financial results, including consistently strong cash flow generation.

We believe we are well positioned to capitalize on important long-term growth trends in the rapidly changing storage industry - the ongoing expansion in digital content and the growth in the amount of that content being stored. These trends are linked directly to consumers’ and commercial enterprises’ increasingly ubiquitous experience with data and the increasing value of that data. The confluence of data growth and the ability to expand the extraction of value from data is driving the need for the long-term retention of as much data as possible for legal and regulatory purposes and for potential future refinements in a wide range of fields. We believe the ways in which people and organizations are creating and using data are changing and that the amount of data considered useful to store is expanding. We also believe we are strongly positioned to play a role in the continuation of these trends as an enabler of the creation and storage of additional data. With a focus on innovation and value creation, our goal is to grow through continued strong execution and with targeted investments in datacenter infrastructure, mobility and the cloud.

Due to regulatory requirements, we operate our global business through two independent subsidiaries - HGST and WD, both long-time innovators in the storage industry. In March 2014, we submitted an application to the Ministry of Commerce of the People’s Republic of China (“MOFCOM”) to lift the condition it imposed on our Company to operate these businesses separately. At this time, we are awaiting MOFCOM’s response to our application.

Our headquarters are located in Irvine, California. WDC was founded in 1970 as a specialized semiconductor manufacturer and since entering the hard drive industry in 1988, its WD subsidiary has been a technology standard-setter in the industry’s highest volume markets. HGST, a provider of high-value storage in enterprise markets, was acquired by WDC in March 2012. HGST was founded in 2003 through the combination of the HDD businesses of International Business Machines Corporation, the inventor of the HDD, and Hitachi, Ltd. (“Hitachi”). As of June 27, 2014, WDC had approximately 9,400 engineers and one of the industry’s largest patent portfolios with more than 7,000 active patents worldwide.

HGST and WD have relationships with the full range of customers currently addressing storage opportunities. These include storage subsystem suppliers, major server original equipment manufacturers (“OEMs”), Internet and social media infrastructure players, and personal computer (“PC”) and Mac™ OEMs. Through HGST and WD, we sell our products to OEMs, distributors, resellers, cloud infrastructure players, and consumers. We have a strong consumer brand heritage with our WD and G-Technology branded products businesses.

The storage market in which we operate is rapidly changing and evolving. To address these dynamics, we regularly review opportunities to apply our knowledge of data storage technology to markets that we do not currently serve or in markets where we seek to broaden our participation and augment our resources and capabilities. We have taken actions to strengthen our enterprise SSD business with the acquisitions of sTec, Inc. (“sTec”), VeloBit, Inc. ("VeloBit") and Virident Systems, Inc. ("Virident"), and our strategic investments in Skyera, Inc., a provider of enterprise solid-state storage systems, Tegile Systems, Inc., a provider of hybrid storage arrays, and Avere Systems, a supplier of enterprise storage for the hybrid cloud. In making these investments, we seek to develop strategic relationships with technology innovators in the broader storage market to enable our customers to develop highly optimized storage solutions that meet their changing data management needs. We believe we have the technology building blocks to increase our overall market participation and be a full-line data storage solutions supplier. Consistent with our measured and deliberate approach to new market entries in the 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.

Industry

The growth and changes in the global market for digital content storage solutions are being driven by several factors including:

• Proliferation of data. The proliferation of consumer electronics, computing devices, social media and cloud-related infrastructure is driving rapid growth in the creation, sharing and retention of high definition video, high resolution images, e-mail and big data files.

• Evolution in data access and distribution. Increasing demand for data access and distribution anytime and anywhere, facilitated by rapidly improving network accessibility, big data analytics and higher bandwidth, is powering a dramatic increase in the need for data storage at both the local level and at the off-site, network-accessed or “cloud” levels.

• Advancements in storage devices. Technological improvements in the capacity, size, performance, connectivity and power requirements of storage devices continue to meet the demand for higher density and higher performance storage in increasingly diverse applications.

• Growth in consumers’ use of mobile computing and storage and use of digital content in the home and small office.

• Adoption of tiered storage architectures. With the significant increase in data storage demand, enterprises and cloud infrastructure players have adopted tiered storage architectures to improve storage performance and manage the costs of this growth. Tiered storage architectures optimize data storage to the most appropriate storage device, driving increasing demand for high capacity and high performance HDDs and flash-based solid-state storage.

• The development of advanced storage solutions that bypass tiered architectures while delivering the same benefits.

We are a market and customer driven company, focused on growth, innovation and value creation for our customers, employees and shareholders. We develop deep and collaborative relationships with customers aimed at making them more successful, an approach that is being manifested in our role as a trusted advisor and market maker in our served markets. We believe this approach is one of the key factors that will help us continue to achieve strong financial performance. We believe our platform is broad-based and powerful, with growth drivers and unique competitive advantages that will continue to provide us the opportunity to expand our value-creation model within an evolving, changing and growing storage market.

The ability to store large amounts of data is an ongoing enabler of the large amount of digital content being created and utilized. We believe the growth in the number of computing users and connected mobile devices in the world continues unabated, creating more usage and more digital content to be stored. Cloud computing applications are especially noteworthy given that they create multiple copies of photos, videos and other content to ensure efficient distribution and security. We believe unit volumes in the HDD industry were up 3% in fiscal 2014 from fiscal 2013, reflecting strength in gaming and the HDD enterprise markets. In addition, we believe unit volumes in the SSD industry were up 24% in fiscal 2014 from fiscal 2013, reflecting strength in SSD enterprise markets.

Enterprise

Enterprise storage devices consist of performance and capacity HDDs, and SSDs. All of these devices are used in multiple types of enterprise datacenters that provide storage for a range of cloud and corporate applications. Within datacenters, these drives are typically used in servers and storage systems.

Performance applications are essential to the operations of an enterprise and require the greatest capabilities and reliability in HDDs and SSDs. These drives are the most highly engineered product line in the storage industry. The infrastructure to support cloud computing storage is driving the demand for multi-platter high capacity HDDs and enterprise class SSDs in tiered architectures. Cloud computing delivers shared resources, software and information to users on demand on a multitude of devices, such as client PCs, tablets and smart phones. Most cloud computing models consist of services delivered through large datacenters with enterprise-class servers, utilizing tiered architectures to address multiple levels of storage needs. We believe we have established a leading position in supplying advanced multi-platter high capacity HDDs and SSDs to address these needs.

We believe shipments into the enterprise market of the storage industry were up 12% in fiscal 2014 from fiscal 2013. We believe that high capacity HDDs, performance HDDs and SSDs represented 46%, 45% and 9% of the industry unit shipments into enterprise systems in fiscal 2014, respectively. Future growth in the enterprise segment is expected to occur based on public and private cloud-related projects to address the continued growth in data being created and the demand to store much of that data.

Client: Desktop and Notebook PCs

Client storage devices consist of internal HDDs and SSDs for desktop and mobile PCs. Desktop PCs are intended for regular use at single locations in homes and businesses, as well as in multi-user educational and government networks. Mobile PCs, primarily notebook computers, are used both in and away from homes and businesses. We believe that the demand for client computer HDDs and SSDs will continue primarily due to demand in emerging countries, corporate and consumer refreshes, the proliferation of digital content and changing requirements for increasing performance and thinner and lighter devices with lower power consumption.

Mobile HDDs for notebook PCs, have traditionally been in a 2.5-inch form factor with a 9.5 mm height. We believe we have led a trend toward thinner, lighter devices with extended battery life and low power consumption with our family of 7 mm height drives and more recently with our 5 mm height drives. Mobile hybrid drives have not yet attracted widespread adoption due to the challenges of managing the overall cost of PC systems, including new features such as touch screens and sleek designs.

We believe the PC market, which includes notebook and desktop PCs and comprises the client market, was down 5% in fiscal 2014 from fiscal 2013 due to the diversification of the digital content storage market. While the PC market remains the storage industry’s largest unit volume market, it has been declining in recent years while other markets such as cloud, traditional enterprise, branded products, gaming and other solutions have been expanding. Although still in decline, we saw a reduction in the rate of decline in PCs over the last several quarters of fiscal 2014 and we believe the rate of decline in the PC market has moderated.

We believe industry unit shipments of mobile HDDs into the client space decreased 7% in fiscal 2014 from fiscal 2013, while unit shipments of desktop HDDs increased 2% in fiscal 2014 from fiscal 2013. We believe industry unit shipments of SSDs into client compute systems increased 20% in fiscal 2014 from fiscal 2013, while unit shipments of SSDs in PCs increased 40% in fiscal 2014 from fiscal 2013.

Branded Products

External storage devices supplement the storage space on PC systems for home and small office networks and, through wireless connections, the fastest growing category in this market, provide remote access to personal content. These drives, when directly attached to PCs, are ideally suited to back up the data already stored on PC internal drives because of their portability and security features. The growing availability of wireless connectivity is spurring growth of external networked attached storage solutions such as our family of WD My Cloud^TM products. We believe HDD shipments into the external storage market increased 2% in fiscal 2014 from fiscal 2013. Branded products also include media players that connect to a user’s television or home theater system and play digital movies, music and photos from an integrated HDD, Universal Serial Bus (“USB”) mass storage device or content services accessed over the Internet.

Consumer Electronics

HDDs for consumer electronics ("CE") products are primarily used in digital video recorders (“DVRs”), game consoles and security video recording systems. We believe demand for greater storage capacity in these applications will continue to drive growth for higher capacity HDDs.

DVRs offer greater consumer viewing flexibility and enhanced capabilities such as pausing live television, simplifying the process of recording and cataloging recorded television programs and quickly forwarding or returning to any section of a recorded television program. Game consoles enable users to save games, movies, music, pictures and other user generated content. Security surveillance hard drives provide 24/7 reliability and peace of mind for the installation of home or small to medium sized business (“SMB”) security systems. We believe HDD unit shipments into the CE market increased 35% in fiscal 2014 from fiscal 2013. This increase was due in part to a refresh cycle by the world’s two largest game console makers, who introduced new models in fiscal 2014, both of which feature HDDs as standard equipment.

Competition

We compete with manufacturers of HDDs for client compute, client non-compute and enterprise applications and manufacturers of SSDs. The HDD market consists of five principal brands: HGST, Samsung, Seagate, Toshiba and WD. In solid-state products, we compete with a wide range of manufacturers, from small startup companies to multinational corporations, including Intel Corporation, Micron Technology, Inc., Samsung Electronics Co. Ltd., SanDisk Corporation, Seagate Technology LLC and Toshiba Corporation.

7

The storage industry is increasingly utilizing tiered architectures with HDDs and SSDs to address an expanding set of uses and applications. HDDs are highly substitutable due to industry standards that mandate the technical form, fit and function of HDDs, and we believe there are no substantial barriers for existing HDD competitors to offer competing products. HDD attributes include 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, market and use, and we believe that we are generally competitive in all of these factors. Semiconductor media or solid-state technology provides high performance attributes in some enterprise-class applications and client notebook designs and attractive functionality in consumer handheld applications requiring smaller form factors, lower power and less storage capacity, such as smart phones and tablets. With advances in our own solid-state enterprise business, coupled with our actions to strengthen those resources through acquisitions and investments, we believe we are positioned to compete successfully in the enterprise-class solid-state segment of this market. Advances in magnetic, optical or other data storage technologies could also result in competitive products for storing digital content with better performance or lower cost per unit of capacity than our products. We monitor the advantages, disadvantages and advances of the full array of storage technologies on an ongoing basis.

Technology

Hard Disk Drives

HDDs provide non-volatile data storage, which means that the data remains present when power is no longer applied to the device. The primary measures of hard drive performance include:

• Acoustics — sound power emitted during hard drive operation, commonly expressed in decibels, and perceived loudness due to sound pressure, commonly expressed in sones;

9

• Data transfer rate — sustained rate of data transfer to and from the disk, commonly expressed in gigabits per second;

• Power consumption — which is the amount of electricity required to operate the drive, measured in watts;

• Seek time — time needed to position the heads over a selected track on the disk surface, commonly expressed in milliseconds;

• Spindle rotation speed — nominal rotation speed of the disks inside the hard drive, commonly expressed in RPM or latency. Spindle rotation speeds commonly stated as 5,400, 7,200, 10,000 and 15,000 RPM are sometimes approximations; and

• Storage capacity — which is the amount of data that can be stored on the hard drive, commonly expressed in GB or TB.

The storage capacity of a hard drive is determined by the number of disks and each disk’s areal density (track density multiplied by bit density), which is a measure of the amount of data that can be stored on the recording surface of the disk per unit area. Head and magnetic media technologies are two of the key technology components of hard drives affecting areal density. We develop and manufacture a substantial portion of the heads and magnetic media used in our hard drive products. As areal density increases, achieving a given drive capacity potentially reduces product costs over time through reduced component requirements. We also invest considerable resources in research and development, manufacturing infrastructure and capital equipment of head and magnetic media components in order to secure our competitive position and cost structure.

Industry-standard interfaces allow the drives to communicate with the host system. The primary interface for PCs is SATA and the primary interfaces for enterprise systems are Fibre Channel, SAS, SATA and PCIe.

Solid-State Drives

SSDs use semiconductor, non-volatile media, rather than magnetic media and magnetic heads, to store and allow fast access to data without any moving parts. The cost per bit of solid-state drives is more expensive than hard drives, but the higher input/output (“IO”) performance makes solid-state drives an attractive new tier of storage that fits between DRAM memory and hard drives. Solid-state drives are finding growing usage in enterprise storage systems and servers in applications that demand the highest IO performance.

The non-volatile memory in use today for solid-state drives is NAND flash technology. While Single Level Cell Flash provides the highest endurance and performance, the optimal balance of price and performance is usually achieved through the use of Multi-Level Cell Flash. Multiple NAND Flash die are used on a single PCBA and connected in parallel through a controller to the host bus. Various performance classes of solid-state drives are created by varying the number of parallel NAND channels and the speed of controller logic and firmware. The controller contains hardware logic and firmware to buffer the data flow to and from the host, to the NAND Flash, and to manage the reliability and performance of the NAND Flash media.

The typical host interfaces for SSDs include PCIe, SAS and SATA. PCIe products typically offer the highest performance and come on edge cards that plug into the PCIe bus. PCIe defines the hardware and electrical interface but the software protocols are still proprietary today. New standards such as NVMe and SCSI express are emerging to bring more standardized software protocols for communicating with PCIe solid-state drives. SAS and SATA products utilize standardized interfaces similar to hard drives and come in 2.5-inch form factors with differing package heights depending on the application and usage. The typical power consumption for the SAS and SATA interfaces is similar to hard drives, while the power consumption of PCIe form factor devices is typically higher.

Our products generally leverage a common platform for various products within product families, and in some cases across product families, resulting in the commonality of components which reduces our exposure to changes in demand, facilitates inventory management and allows us to achieve lower costs through purchasing economies. This platform strategy also enables our customers to leverage their qualification efforts onto successive product models.

Research and Development

We devote substantial resources to the development of new products and the improvement of existing products. We focus our engineering efforts on coordinating our product design and manufacturing processes to bring our products to market in a cost-effective and timely manner. Research and development expenses totaled $1.7 billion, $1.6 billion and $1.1 billion in 2014, 2013 and 2012, respectively. For a discussion of associated risks, see Item 1A of this Annual Report on Form 10-K.

Patents, Licenses and Proprietary Information

We have more than 7,000 active patents and have many patent applications in process. We believe that although our active 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 our products. We believe that we have adequate cross-licenses and other agreements in place in addition to our own intellectual property portfolio to compete successfully in the storage industry. For a discussion of associated risks, see Item 1A of this Annual Report on Form 10-K.

Manufacturing

We believe that we have significant know-how, unique product manufacturing processes, test and tooling, execution skills and human resources to continue to be successful and to grow, as necessary, our manufacturing operations. We strive to maintain manufacturing flexibility, high manufacturing yields, reliable products, and high-quality components. The critical elements of our HDD production are high volume and utilization, low cost assembly and testing, strict adherence to quality metrics and maintaining close relationships with our strategic component suppliers to access best-in-class technology and manufacturing capacity.

HDD manufacturing is a complex process involving the production and assembly of precision components with narrow tolerances and thorough testing. The assembly process occurs in a “clean room” environment that demands skill in process engineering and efficient space utilization to control the operating costs of this manufacturing environment. Our clean room manufacturing process consists of modular production units, each of which contains a number of work cells. We continually evaluate our manufacturing processes in an effort to increase productivity, sustain and improve quality and decrease manufacturing costs. We continually evaluate which steps in the manufacturing process would benefit from automation and how automated manufacturing processes can improve productivity and reduce manufacturing costs. For our non- HDD products, we leverage the efficiencies of contract manufacturers when strategically advantageous. For a discussion of associated risks, see Item 1A of this Annual Report on Form 10-K.

Materials and Supplies

The main components of the hard drive are a Head-Disk-Assembly (“HDA”) and a Printed Circuit Board Assembly (“PCBA”).

The HDA includes heads, magnetic media, head positioning mechanism (“actuator”) and spindle motor. A rigid base and top cover contain these components in a contamination-controlled environment. One or more disks positioned around a motor-driven spindle hub that rotates the disks comprise the disk-pack assembly. The disk is made up of a smooth substrate on which thin layers of magnetic materials are deposited. The head stack assembly (“HSA”) is comprised of a magnetic positioner and a pivot-arm module on which the head gimbal assemblies ("HGAs"), including suspension, are mounted. Each disk surface has a head suspended directly above it, which can read data from or write data to the spinning disk. Other key components of our hard drives are pre-amps and voice coil magnets.

The PCBA includes both standard and custom integrated circuits, an interface connector to the host computer and a power connector. The integrated circuits on the printed circuit board typically include a power device that controls the motor and HSA positioner, and a System-on-Chip (“SoC”) comprised of a drive interface, controller and recording channel. The drive interface

11

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.

We design and manufacture a substantial portion of the heads and magnetic media required for our products. 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. We depend on an external supply base for all remaining components and materials for use in our HDD product design and manufacturing.

The key components used in the manufacture of our SSDs are the NAND semiconductor media and SoC which are acquired from third party suppliers. The NAND flash products used in our SSDs are sourced from multiple tier-one NAND manufacturers. We have established deep relationships with these vendors to assure continuous supply of NAND, as well as sufficient technical depth of technology access to enable continuous cost and technology leadership of our SSD product portfolio offering. Additionally, we are exploring strategic options to further strengthen and deepen our collaboration with select NAND partners to support the future growth of our SSD business. Additionally, the key component in our media players, the controller, is acquired from third party suppliers.

We believe that our sourcing strategy currently enables us to have the business flexibility needed to select the highest quality, low cost of ownership suppliers as product designs and technologies evolve. We generally retain multiple suppliers for each of our component requirements but in some instances use sole sources for business reasons. Currently, we believe that there are no major issues with component availability. For a discussion of associated risks, see Item 1A of this Annual Report on Form 10-K.

Sales and Distribution

We maintain sales offices in selected parts of the world including the major geographies of the Americas, Asia Pacific, Europe and the Middle East. Our international sales, which include sales to foreign subsidiaries of United States (“U.S.”) companies but do not include sales to U.S. subsidiaries of foreign companies, represented 80%, 78% and 81% of our net revenue for 2014, 2013 and 2012, respectively. Sales to international customers are subject to certain risks not normally encountered in domestic operations, including exposure to tariffs and various trade regulations. For a discussion regarding associated risks, see Item 1A of this Annual Report on Form 10-K.

We perform our marketing and advertising functions internally and through outside firms utilizing both consumer media and trade publications targeting various reseller and end-user categories. We also maintain customer relationships through direct communication and providing information and support through our Web site. In accordance with standard storage industry practice, we provide distributors and retailers with limited price protection and programs under which we reimburse certain marketing expenditures. We also provide distributors, resellers and OEMs with other sales incentive programs.

Original Equipment Manufacturers. OEMs, including large-scale datacenter operators, purchase our products, either directly or through a contract manufacturer such as an original design manufacturer (“ODM”), and assemble them into the devices they build. OEMs typically seek to qualify two or more providers for each generation of products and generally will purchase products from those vendors for the life of that product. Many of our OEM customers utilize just-in-time inventory management processes. As a result, for certain OEMs we maintain a base stock of finished goods inventory in facilities located near or adjacent to the OEM’s operations. In addition, we also sell directly to cloud infrastructure players, which we classify as OEMs for purposes of channel information.

Distributors. We use a broad group of distributors to sell our products to non-direct customers such as small computer and CE manufacturers, dealers, systems integrators, online retailers and other resellers. Distributors generally enter into non-exclusive agreements with us for the purchase and redistribution of our products in specific territories.

Retailers. We sell our branded products directly to a select group of major retailers such as computer superstores, warehouse clubs, online retailers, and computer electronics stores, and authorize sales through distributors to smaller retailers. The retail channel complements our other sales channels while helping to build brand awareness for us and our products. We also sell our branded products through our Web sites.

For each of 2014 and 2012, sales to Hewlett Packard Company accounted for 11% of our net revenue. For 2013, no single customer accounted for 10% or more of our net revenue. For a discussion of associated risks, refer to Item 1A of this Annual Report on Form 10-K. For additional information regarding revenue recognition, sales by geographic region and major

12

customers, 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.

Backlog

A substantial portion of our orders are generally for shipments within 30 to 60 days of the placement of the order. Customers’ purchase orders typically may be canceled with relatively short notice to us, with little or no cost to the customer, or modified by customers to provide for delivery at a later date. In addition, for many of our OEMs utilizing just-in-time inventory, we do not generally require firm order commitments and instead, receive a periodic forecast of requirements. Therefore, backlog information as of the end of a particular period is not necessarily indicative of future levels of our revenue and profit and may not be comparable to prior periods.

Seasonality

We have historically experienced seasonal fluctuations in our business with higher levels of demand in the first and second quarters of our fiscal year as a result of increased customer spending. Seasonality can also be impacted by the growth in emerging markets and macroeconomic conditions. For a discussion of associated risks, see Item 1A of this Annual Report on Form 10-K.

Service and Warranty

We generally warrant our newly manufactured products against defects in materials and workmanship from one to five years from the date of manufacture depending on the type of product. Our warranty obligation is generally limited to repair or replacement. We have engaged third parties in various countries in multiple regions to provide various levels of testing, processing or recertification of returned products for our customers. For a further discussion of our service and warranty policy, see Part II, Item 8, Note 1 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

Environmental Regulation

We are subject to a variety of U.S. and foreign laws and regulations in connection with our operations and relating to the protection of the environment, including those governing discharges of pollutants into the air and water, the management and disposal of hazardous substances, and the cleanup of contaminated sites. Some of our operations require environmental permits and controls to prevent and reduce air and water pollution. These permits are subject to modification, renewal and revocation by issuing authorities. We believe that we have obtained or are in the process of obtaining all necessary environmental permits for our operations.

We have established environmental management systems and continually update our environmental policies and standard operating procedures for our operations worldwide. We believe that our operations are in material compliance with applicable environmental laws, regulations and permits. We budget for operating and capital costs on an ongoing basis to comply with environmental laws.

Our properties have in some cases been operated for many years and may contain soil or groundwater contamination. In certain of our facilities we are undertaking voluntary monitoring of soil and groundwater. Based on available information, including our voluntary monitoring activities, we do not believe that we have a current affirmative legal obligation for any remedial action.

For a discussion of associated risks, see Item 1A of this Annual Report on Form 10-K.

Employees

As of June 27, 2014, we employed a total of 84,072 employees worldwide, excluding temporary employees and contractors. Many of our employees are highly skilled, and our continued success depends in part upon our ability to attract and retain such employees. Accordingly, we offer employee benefit programs which we believe are, in the aggregate, competitive with those offered by our competitors.

While the substantial majority of our employees are not party to a collective bargaining agreement, a majority of our employees in Japan and employees of two of our manufacturing subsidiaries in China are subject to a collective bargaining agreement. While our third manufacturing subsidiary in China has its own labor union of which many of its direct employees are members, it has yet to begin collective bargaining negotiations. We consider our employee relations to be good. For a discussion of associated risks, see Item 1A of this Annual Report on Form 10-K.

Item 1A. Risk Factors

The business, financial condition and operating results of the Company can be affected by a number of factors, whether currently known or unknown, including but not limited to those described below, any one or more of which could, directly or indirectly, cause the Company’s actual results of operations and financial condition to vary materially from past, or from anticipated future, results of operations and financial condition. Any of these factors, in whole or in part, could materially and adversely affect the Company’s business, financial condition, results of operations or the market price of its common stock.

If we fail to realize the anticipated benefits from our acquisition of HGST on a timely basis, or at all, our business and financial condition may be adversely affected.

In connection with obtaining the regulatory approvals required to complete the acquisition of HGST, we agreed to certain conditions required by the Ministry of Commerce of the People’s Republic of China (“MOFCOM”), including adopting measures to keep HGST as an independent competitor until MOFCOM agrees otherwise (with the minimum period being two years from the March 8, 2012 closing date of the acquisition). We worked closely with MOFCOM to finalize an operations plan that outlines in more detail the conditions of the competitive requirement. Compliance with these measures has affected, and may continue to affect, our business and financial conditions in the following ways:

• limits our ability to integrate the businesses of our HGST and WD subsidiaries (and we do not expect to achieve significant operating expense synergies while the hold separate condition continues to exist);

• has caused, and could cause further, difficulties in retaining key employees and delays or uncertainties in making decisions about the combined business;

• has resulted in, and could result in additional, significant costs (including higher capital expenditures relative to our competitors as a result of maintaining separate functions in several areas); and

• has required, and could require additional, changes in business practices.

In March 2014, we submitted an application to MOFCOM requesting that the regulatory restrictions be lifted. However, we cannot predict whether or when these restrictions will be wholly or partially lifted or whether we will be able to realize the anticipated benefits of our acquisition of HGST even if the restrictions are wholly or partially lifted.

15

In connection with obtaining the regulatory approvals required to complete our acquisition of HGST, we divested certain assets to Toshiba and agreed to provide certain support services for those assets for a period of time, and our business will be adversely affected in the event we fail to successfully meet our obligations to Toshiba under the divestiture transaction.

In connection with obtaining the regulatory approvals required to complete our acquisition of HGST, we agreed, subject to review by regulatory agencies in certain jurisdictions, to divest certain assets to Toshiba that would expand Toshiba’s capacity to manufacture 3.5-inch hard drives for the desktop, consumer electronics and near-line (business critical) applications. While this divestiture transaction closed in May 2012, we agreed to provide certain support service for those assets for a period of time. If we are not able to meet our continuing service obligations under our agreement with Toshiba, the jurisdictions that conditioned their approval of the HGST acquisition on the divestiture could impose additional obligations on us, which could adversely affect our business, financial condition and results of operations.

Adverse global economic conditions and credit market uncertainty could harm our business, results of operations and financial condition.

Adverse global economic conditions and uncertain conditions in the credit market have had, and in the future could have, a significant adverse effect on our company and on the storage industry as a whole. Several factors contribute to these conditions and this uncertainty, including, but not limited to, volatility in the financial and real estate markets, cost increases and other macroeconomic factors. Some of the risks and uncertainties we face as a result of these conditions include the following:

• Volatile Demand. 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 rely on credit financing to purchase our products. If negative conditions in the global credit markets prevent our customers’ access to credit, product orders may decrease, which could result in lower revenue. Likewise, if our suppliers, sub-suppliers and sub-contractors (collectively referred to as “suppliers”) face challenges in obtaining credit, in selling their products or otherwise in operating their businesses, they may be unable to offer the materials we use to manufacture our products. These actions could result in reductions in our revenue and increased operating costs, which could adversely affect our business, results of operations and financial condition.

• Restructuring Activities. If demand for our products slows as a result of a deterioration in economic conditions, we may undertake restructuring activities to realign our cost structure with softening demand. The occurrence of restructuring activities could result in impairment charges and other expenses, which could adversely impact our results of operations or financial condition.

• Credit Volatility and Loss of Receivables. We extend credit and payment terms to some of our customers. In addition to ongoing credit evaluations of our customers’ financial condition, we traditionally seek to mitigate our credit risk by purchasing credit insurance on certain of our accounts receivable balances. As a result of the continued uncertainty and volatility in global economic conditions, however, we may find it increasingly difficult to be able to insure these accounts receivable. We could suffer significant losses if a customer whose accounts receivable we have not insured, or have underinsured, fails and is unable to pay us. Additionally, negative or uncertain global economic conditions increase the risk that if a customer whose accounts receivable we have insured fails, the financial condition of the insurance carrier for such customer account may have also deteriorated such that it cannot cover our loss. A significant loss of an accounts receivable that we cannot recover through credit insurance would have a negative impact on our financial results.

• Impairment Charges. Negative or uncertain global economic conditions could result in circumstances, such as a sustained decline in our stock price and market capitalization or a decrease in our forecasted cash flows such that they are insufficient, indicating that the carrying value of our long-lived assets or goodwill may be impaired. If we are required to record a significant charge to earnings in our consolidated financial statements because an impairment of our long-lived assets or goodwill is determined, our results of operations will be adversely affected.

16

We participate in a highly competitive industry that is subject to the risk of declining average selling prices ("ASPs"), volatile gross margins and significant shifts in market share, all of which could adversely affect our operating results.

Demand for our devices, software and solutions that we offer to our customers, which we refer to in this Item 1A. as our “products”, depends in large part on the demand for systems manufactured by our customers and on storage upgrades to existing systems. The demand for systems has been volatile in the past and often has had an exaggerated effect on the demand for our products in any given period. As a result, the storage market has experienced periods of excess capacity, which can lead to liquidation of excess inventories and more intense price competition. If more intense price competition occurs, we may be forced to lower prices sooner and more than expected, which could adversely impact revenue and gross margins. In addition, we compete based on our ability to offer our customers competitive solutions that provide the most current and desired product and service features. We expect that competition will continue to be intense, and there is a risk that our competitors’ products may be less costly, provide better performance or include additional features when compared to our products. Our ASPs and gross margins also tend to decline when there is a shift in the mix of product sales, and sales of lower priced products increase relative to those of higher priced products. In addition, rapid technological changes often reduce the volume and profitability of sales of existing products and increase the risk of inventory obsolescence. These factors, along with others, may result in significant shifts in market share among the industry’s major participants, including a substantial decrease in our market share.

Our failure to accurately forecast market and customer demand for our products, or to quickly adjust to forecast changes, could adversely affect our business and financial results or operating efficiencies.

The data storage industry faces difficulties in accurately forecasting market and customer demand for its products. The variety and volume of products we manufacture is based in part on these forecasts. Accurately forecasting demand has become increasingly difficult for us, our customers and our suppliers in light of the volatility in global economic conditions and industry consolidation, resulting in less availability of historical market data for certain product segments. In addition, because our products are designed to be largely interchangeable with competitors’ products, our demand forecasts may be impacted significantly by the strategic actions of our competitors. As forecasting demand becomes more difficult, the risk that our forecasts are not in line with demand increases. If our forecasts exceed actual market demand, then we could experience periods of product oversupply and price decreases, which could impact our financial performance. If market demand increases significantly beyond our forecasts or beyond our ability to add manufacturing capacity, then we may not be able to satisfy customer product needs, possibly resulting in a loss of market share if our competitors are able to meet customer demands.

We experience significant sales seasonality and cyclicality, which could cause our operating results to fluctuate.

Sales of computer systems, storage subsystems and CE tend to be seasonal and cyclical, and therefore we expect to continue to experience seasonality and cyclicality in our business as we respond to variations in our customers’ demand for our products. However, changes in seasonal and cyclical patterns have made it, and could continue to make it, more difficult for us to forecast demand, especially as a result of the current macroeconomic environment. Changes in the product or channel mix of our business can also impact seasonal and cyclical patterns, adding complexity in forecasting demand. Seasonality and cyclicality also may lead to higher volatility in our stock price. It is difficult for us to evaluate the degree to which seasonality and cyclicality may affect our stock price or business in future periods because of the rate and unpredictability of product transitions and new product introductions and macroeconomic conditions.

Our sales to the CE, cloud computing and enterprise markets, representing an increasing percentage of our overall revenue, may grow at a slower rate than current estimates, which could materially adversely impact our operating results.

The secular growth of digital data is resulting in a more diversified mix of revenue from the CE, cloud computing and enterprise markets. As sales into these markets become a more significant portion of our revenue, events or circumstances that adversely impact demand in these markets, or our inability to address that demand successfully, could materially adversely impact our operating results. For example, demand in, or our sales to, these markets may be adversely affected by the following:

• Mobile Devices. There has been and continues to be a rapid growth in devices that do not contain a hard drive such as tablet computers and smart phones. As tablet computers and smart phones provide many of the same capabilities as PCs, they have displaced or materially affected, and may continue to displace or materially affect, the demand for PCs. If we are not successful in adapting our product offerings to include disk drives or alternative storage solutions that address these devices, demand for our products in these markets may decrease and our financial results could be materially adversely affected.

17

• Cloud Computing. Consumers traditionally have stored their data on their PC, often supplemented with personal external storage devices. Most businesses also include similar local storage as a primary or secondary storage location. This storage is typically provided by hard disk drives. Over the last few years, cloud computing has emerged whereby applications and data are hosted, accessed and processed through a third-party provider over a broadband Internet connection, potentially reducing or eliminating the need for, among other things, significant storage inside the accessing computer. If we are not successful in manufacturing compelling products to address the cloud computing opportunity, demand for our products in these markets may decrease and our financial results could be materially adversely affected.

• Obsolete Inventory. In some cases, products we manufacture for these other markets are uniquely configured for a single customer’s application, creating a risk of obsolete inventory if anticipated demand is not actually realized.

• Macroeconomic Conditions. Consumer spending has been, and may continue to be, adversely affected in many regions due to negative macroeconomic conditions and high unemployment levels. Please see the risk factor entitled “Adverse global economic conditions and credit market uncertainty could harm our business, results of operations and financial condition.” for more risks and uncertainties relating to macroeconomic conditions.

In addition, demand in these other markets also could be negatively impacted by developments in the regulation and enforcement of digital rights management and the emergence of new technologies, such as data deduplication, compression and storage virtualization. If we are not able to respond appropriately, these factors could lead to our customers’ storage needs being satisfied at lower prices with lower capacity hard drives or solid-state storage products, thereby decreasing our revenue or putting us at a disadvantage to competing storage technologies. As a result, even with increasing aggregate demand for digital storage, if we fail to anticipate or timely respond to these developments in the demand for storage, our ASPs could decline, which could adversely affect our operating results. Furthermore, our ability to accurately read and respond to market trends, such as trends relating to the Internet or big data, could harm our results.

If we fail to respond to changes in the client compute market (the “PC market”), our operating results could suffer.

While sales to the other markets are becoming a more significant source of revenue, sales to the PC market remain an important part of our business. The PC market, however, has been, and may continue to be, adversely affected by the growth of tablet computers, smart phones and similar devices that perform many of the same capabilities as PCs, the lengthening of product life cycles and macroeconomic conditions. If we fail to respond to changes in the PC market, our operating results could suffer. Additionally, if demand in the PC market is worse than expected as a result of these or other conditions, demand for our products in the PC market may decrease at a faster rate and our operating results may be adversely affected.

Selling to the retail market is an important part of our business, and if we fail to maintain and grow our market share or gain market acceptance of our branded products, our operating results could suffer.

Selling branded products is an important part of our business, and as our branded products revenue increases as a portion of our overall revenue, our success in the retail market becomes increasingly important to our operating results. Our success in the retail market depends in large part on our ability to maintain our brand image and corporate reputation and to expand into and gain market acceptance of our products in multiple channels, including traditional retail, e-commerce and online channels. Adverse publicity, whether or not justified, or allegations of product or service quality issues, even if false or unfounded, could tarnish our reputation and cause our customers to choose products offered by our competitors. In addition, the proliferation of new methods of mass communication facilitated by the Internet makes it easier for false or unfounded allegations to adversely affect our brand image and reputation. If customers no longer maintain a preference for WD^®, HGST™ or G-Technology™ brand products, our operating results may be adversely affected.

Sales in the distribution channel are important to our business, and if we fail to respond to demand changes in distribution markets or if distribution markets for our products weaken, our operating results could suffer.

Our distribution customers typically sell to small computer manufacturers, dealers, systems integrators and other resellers. We face significant competition in this channel as a result of limited product qualification programs and a significant focus on price and availability of product. In addition, the PC market is experiencing a shift to notebook and other mobile devices and, as a result, more computing devices are being delivered to the market as complete systems, which could weaken the distribution market. If we fail to respond to changes in demand in the distribution market, our operating results could suffer. Additionally, if the distribution market weakens as a result of a slowing PC growth rate, technology transitions or a significant change in consumer buying preference, or if we experience significant price declines due to demand changes in the distribution channel, then our operating results would be adversely affected.

Loss of market share with or by a key customer, or consolidation among our customer base, could harm our operating results.

During the quarter ended June 27, 2014, 45% of our revenue came from sales to our top 10 customers and during the fiscal year ended June 27, 2014, 44% of our revenue came from sales to such 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, often resulting in the allocation of risk to us as the supplier. Our ability to maintain strong relationships with our principal customers is essential to our future performance. If we lose a key customer, if any of our key customers reduce their orders of our products or require us to reduce our prices before we are able to reduce costs, if a customer is acquired by one of our competitors or if a key customer suffers financial hardship, our operating results would likely be harmed.

Additionally, if there is consolidation among our customer base, our customers may be able to command increased leverage in negotiating prices and other terms of sale, which could adversely affect our profitability. In addition, if, as a result of increased leverage, customer pressures require us to reduce our pricing such that our gross margins are diminished, we could decide not to sell our products to a particular customer, which could result in a decrease in our revenue. Consolidation among our customer base may also lead to reduced demand for our products, replacement of our products by the combined entity with those of our competitors and cancellations of orders, each of which could harm our operating results.

Also, the storage ecosystem is constantly evolving, and our traditional customer base is changing. Fewer companies now hold greater market share for certain applications and services, such as social media, shopping and streaming media. As a result, the competitive landscape is changing, giving these companies increased leverage in negotiating prices and other terms of sale, which could adversely affect our profitability. In addition, the changes in our evolving customer base create new selling and distribution patterns to which we must adapt. To remain competitive, we must respond to these changes by ensuring we have proper scale in this evolving market, as well as offer products that meet the technological requirements of this customer base at competitive pricing points. To the extent we are not successful in adequately responding to these changes, our operating results could be harmed.

Expansion into new markets may increase the complexity of our business, cause us to increase our research and development expenses to develop new products and technologies or cause our capital expenditures to increase, and if we are unable to successfully adapt our business processes and product offerings as required by these new markets, our ability to grow will be adversely affected.

To remain a significant supplier in the storage industry and to expand into new markets, we will need to offer a broad range of storage products to our customers. We currently offer a variety of 3.5-inch and 2.5-inch hard drives, solid state drives and other products for the PC and other storage markets. As we expand our product line to sell into new markets, the overall complexity of our business increases at an accelerated rate and we become subject to different market dynamics. These dynamics may include, among other things, different demand volume, seasonality, product requirements, sales channels, and warranty and return policies. In addition, expansion into other markets may result in increases in research and development expenses and substantial investments in manufacturing capability or technology enhancements. If we fail to successfully expand into new markets with products that we do not currently offer, we may lose business to our competitors or new entrants who offer these products.

Our vertical integration of head and magnetic media manufacturing makes us dependent on our ability to timely and cost-effectively develop heads and magnetic media with leading technology and overall quality, increasing capital expenditure costs and asset utilization risks for our business.

We develop and manufacture a substantial portion of the heads and magnetic media used in the hard drive products we produce. Consequently, we are more dependent upon our own development and execution efforts and less able to take advantage of head and magnetic media technologies developed by other manufacturers. Technology transition for head and magnetic media designs is critical to increasing our volume production of heads and magnetic media. There can be no assurance, however, that we will be successful in timely and cost-effectively developing and manufacturing heads or magnetic media for products using future technologies. We also may not effectively transition our head or magnetic media design and technology to achieve acceptable manufacturing yields using the technologies necessary to satisfy our customers’ product needs, or we may encounter quality problems with the heads or magnetic media we manufacture. If we are unable to timely and cost-effectively develop heads and magnetic media with leading technology and overall quality, our ability to sell our products may be significantly diminished, which could materially and adversely affect our business and financial results.

In addition, as a result of our vertical integration of head and magnetic media manufacturing, we make more capital investments and carry a higher percentage of fixed costs than we would if we were not vertically integrated. If our overall level of production decreases for any reason, and we are unable to reduce our fixed costs to match sales, our head or magnetic media manufacturing assets may face underutilization that may impact our operating results. We are therefore subject to additional

19

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, as a result of adverse labor rates or availability, we may be required to increase investments in automation, which may cause our capital expenditures to increase. If we do not adequately address the challenges related to our head or magnetic media manufacturing operations, our ongoing operations could be disrupted, resulting in a decrease in our revenue or profit margins and negatively impacting our operating results.

We make significant investments in research and development to improve our technology and develop new technologies, and unsuccessful investments could materially adversely affect our business, financial condition and results of operations.

As a leading supplier of hard drives and a major supplier of enterprise solid state drives, we make significant investments to maintain our existing products and to lead innovation and development of new technologies. This strategy requires us to make significant investments in research and development and, in order to remain competitive, we may increase our capital expenditures and expenses above our historical run-rate model. There can be no assurance that these investments will result in viable technologies or products, or if these investments do result in viable technologies or products, that they will be profitable or accepted by the market. Significant investments in unsuccessful research and development efforts could materially adversely affect our business, financial condition and results of operations. In addition, increased investments in technology could cause our cost structure to fall out of alignment with demand for our products, which would have a negative impact on our financial results.

Current or future competitors may gain a technology advantage or develop an advantageous cost structure that we cannot match.

It may be possible for our current or future competitors to gain an advantage in product technology, manufacturing technology, or process technology, which may allow them to offer products or services that have a significant advantage over the products and services that we offer. Advantages could be in capacity, performance, reliability, serviceability, or other attributes. A competitive cost structure for our products, including critical components, labor and overhead, is also critical to the success of our business. We may be at a competitive disadvantage to any companies that are able to gain a technological or cost structure advantage.

Consolidation within the data storage industry could provide competitive advantages to our competitors.

The data storage industry as a whole has experienced consolidation over the past several years through acquisitions, consolidations and decisions by industry players to exit the industry. Consolidation across the industry, including by our competitors, may enhance their capacity, abilities and resources and lower their cost structure, causing us to be at a competitive disadvantage.

Some of our competitors with diversified business units outside of storage products, may over extended periods of time, sell storage products at prices that we cannot profitably match.

Some of our competitors earn a significant portion of their revenue from business units outside of storage products. Because they do not depend solely on sales of storage products to achieve profitability, they may sell storage products at lower prices and operate their storage 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-storage products to the same customers, they may benefit from selling their storage products at lower prices. Our operating results may be adversely affected if we cannot successfully compete with the pricing by these companies.

If we fail to qualify our products with our customers, it may have a significant adverse impact on our sales and margins.

We regularly engage in new product qualification with our customers. Once a product is accepted for qualification testing, failures or delays in the qualification process can result in delayed or reduced product sales, reduced product margins caused by having to continue to offer a more costly current generation product, or lost sales to that customer until the next generation of products is introduced. The effect of missing a product qualification opportunity is magnified by the limited number of high volume original equipment manufacturers ("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.

20

We are subject to risks related to product defects or the unintended use of our products, which could result in product recalls or epidemic failures and could subject us to warranty claims in excess of our warranty provisions or which are greater than anticipated.

We warrant the majority of our products for periods of one to five years. We test our products in our manufacturing facilities through a variety of means. However, there can be no assurance that our testing will reveal defects in our products, which may not become apparent until after the products have been sold into the market. In addition, our products may be used in a manner that is not intended or anticipated by us, resulting in potential liability. Accordingly, there is a risk that product defects will occur, which could require a product recall. Product recalls can be expensive to implement and, if a product recall occurs during the product’s warranty period, we may be required to replace the defective product. Moreover, there is a risk that product defects may trigger an epidemic failure clause in a customer agreement. If an epidemic failure occurs, we may be required to replace or refund the value of the defective product and to cover certain other costs associated with the consequences of the epidemic failure. In addition, a product recall or epidemic failure may damage our reputation or customer relationships, and may cause us to lose market share with our customers, including our OEM and original design manufacturers ("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 expenses if our warranty provision do not reflect the actual cost of resolving issues related to defects in our products, whether as a result of a product recall, epidemic failure or otherwise. If these additional expenses are significant, it could adversely affect our business, financial condition and operating results.

In addition, third-party components or applications that we incorporate or use in our products may contain defects in design or manufacturing that could unexpectedly result in epidemic failures and subject us to liability.

Because we are dependent on a limited number of qualified suppliers for components, sub-assemblies, equipment, consumables, raw materials, and logistics, a supplier’s inability, unwillingness, or failure to support us in a timely manner with goods or services at a quality level and cost acceptable to us can adversely affect our margins, revenues and operating results.

We depend on an external supply base for technologies, components, equipment and materials for use in our product design and manufacturing. We also depend on service suppliers for providing technical support for our products. In addition, we use logistics partners to manage our JIT (just-in-time) hubs, distribution centers and freight from suppliers to our factories and from our factories to our customers throughout the world. Many of these components and much of this 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 whom are our sole-source suppliers. 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 into our products, technology and equipment that can be used to develop and manufacture our next-generation products efficiently. However, many of the risks that affect us also affect our supply base, including, but not limited to, having single site manufacturing locations based in high risk regions of the world, macro and local economic conditions, shortages of commodity materials, proper management of technology transitions, natural disasters, geo-political risks, compliance with legal requirements, financial instability and exposure to intellectual property and other litigation, including an injunction or other action that could delay shipping. If any of these risks were to affect our suppliers, we could also be adversely affected, especially in the case of products, components or services that are single-sourced. For example, if suppliers are facing increased costs due to the above risks, they may require us to enter into long-term volume agreements to shift the burden of fixed costs to us. Further, we work closely with many of our suppliers to develop new technologies and, as a result, we may become subject to litigation from our suppliers or third parties.

Without a capable and financially stable supply base that has established appropriate relationships within the supply chain and has implemented business processes, strategies and risk management safeguards, we would be unable to develop our products, manufacture them in high volumes, and distribute them to our customers to execute our business plans effectively. As PC demand slows, competition increases from NAND and other consumer devices, the total available market for hard disk drives decreases and costs increase, these suppliers may reevaluate their business models. Our suppliers may be acquired by our competitors, consolidate, or decide to exit the industry, redirect their investments and increase costs to us, each of which may have an adverse effect on our business and operations. In addition, moving to new technologies may require us to align to, and build, a new supply base, such as NAND flash. In the case of NAND suppliers, many of which are involved in developing storage products such as SSD that, in some cases, compete with our products. Our success in these new product areas may be

21

dependent on our ability and their willingness to develop close relationships, with preferential agreements. Where this cannot be done, our business and operations may be adversely affected.

In addition to an external supply base, we also rely on an internal supply chain of heads, media and media substrate. Please see the risk factors entitled, “A fundamental change in recording technology could result in significant increases in our costs and could put us at a competitive disadvantage” and “If we do not properly manage technology transitions, our competitiveness and operating results may be negatively affected” for a review of some of the risks related to our internal supply.

Price volatility, shortages of critical materials or components, or use by other industries of materials and components used in the storage industry, may negatively impact our operating results.

Increases in the cost for certain critical materials and components and oil may increase our costs of manufacturing and transporting our products and key components and may result in lower operating margins if we are unable to pass these increased costs on to our customers. Shortages of critical components such as DRAM and NAND flash, or materials such as glass substrates, stainless steel, aluminum, nickel, neodymium, ruthenium, platinum or cerium, may increase our costs and may result in lower operating margins if we are unable to find ways to mitigate these increased costs. We or our suppliers acquire certain precious metals and rare earth metals like ruthenium, platinum, neodymium and cerium, which are critical to the manufacture of components in our products from a number of countries, including the People’s Republic of China. The government of China or any other nation may impose regulations, quotas or embargoes upon these metals that would restrict the worldwide supply of such metals or increase their cost, both of which could negatively impact our operating results until alternative suppliers are sourced. Furthermore, if other high volume industries increase their demand for materials or components used in our products, our costs may further increase, which could have an adverse effect on our operating margins. In addition, shortages in other components and materials used in our customers’ products could result in a decrease in demand for our products, which would negatively impact our operating results.

Contractual commitments with component suppliers may result in us paying increased charges and cash advances for such components or may cause us to have inadequate or excess component inventory.

To reduce the risk of component shortages, we attempt to provide significant lead times when buying components, which may subject us to cancellation charges if we cancel orders as a result of technology transitions or changes in our component needs. In addition, we may from time to time enter into contractual commitments with component suppliers in an effort to increase and stabilize the supply of those components and enable us to purchase such components at favorable prices. Some of these commitments may require us to buy a substantial number of components from the supplier or make significant cash advances to the supplier; however, these commitments may not result in a satisfactory increase or stabilization of the supply of such components. Furthermore, as a result of uncertain global economic conditions, our ability to forecast our requirements for these components has become increasingly difficult, therefore increasing the risk that our contractual commitments may not meet our actual supply requirements, which could cause us to have inadequate or excess component inventory and adversely affect our operating results and increase our operating costs.

Changes in product life cycles could adversely affect our financial results.

If product life cycles lengthen, we may need to develop new technologies or programs to reduce our costs on any particular product to maintain competitive pricing for that product. If product life cycles shorten, it may result in an increase in our overall expenses and a decrease in our gross margins, both of which could adversely affect our operating results. In addition, shortening of product life cycles also makes it more difficult to recover the cost of product development before the product becomes obsolete. Our failure to recover the cost of product development in the future could adversely affect our operating results.

A fundamental change in recording technology could result in significant increases in our costs and could put us at a competitive disadvantage.

Historically, when the industry experiences a fundamental change in technology, any manufacturer that fails to successfully and timely adjust its designs and processes to accommodate the new technology fails to remain competitive. There are some revolutionary technologies, such as current-perpendicular-to-plane giant magnetoresistance, shingle magnetic recording, heat-assisted magnetic recording, patterned magnetic media and advanced signal processing that if implemented by a competitor on a commercially viable basis ahead of the industry, could put us at a competitive disadvantage. As a result of these technology shifts, we could incur substantial costs in developing new technologies, such as heads, magnetic media, and tools to remain competitive. If we fail to successfully implement these new technologies, or if we are significantly slower than our competitors at implementing new technologies, we may not be able to offer products with capacities that our customers desire, which could harm our operating results.

22

The difficulty of introducing hard drives with higher levels of areal density and the challenges of reducing other costs may impact our ability to achieve historical levels of cost reduction.

Storage capacity of the hard drive, as manufactured by us, is determined by the number of disks and each disk’s areal density. Areal density is a measure of the amount of magnetic bits that can be stored on the recording surface of the disk. Generally, the higher the areal density, the more information can be stored on a single platter. Higher areal densities require existing head and magnetic media technology to be improved or new technologies developed to accommodate more data on a single disk. Historically, we have been able to achieve a large percentage of cost reduction through increases in areal density. Increases in areal density mean that the average drive we sell has fewer heads and disks for the same capacity and, therefore, may result in a lower component cost. However, increasing areal density has become more difficult in the storage industry. If we are not able to increase areal density at the same rate as our competitors or at a rate that is expected by our customers, we may be required to include more components in our drives to meet demand without corresponding incremental revenue, which could negatively impact our operating margins and make achieving historical levels of cost reduction difficult or unlikely. Additionally, increases in areal density may require us to make further capital expenditures on items such as new test equipment needed as a result of an increased number of gigabytes per platter. Our inability to achieve cost reductions could adversely affect our operating results.

If we do not properly manage technology transitions, our competitiveness and operating results may be negatively affected.

The storage markets in which we offer our products continuously undergo technology transitions which we must anticipate and adapt our products to address in a timely manner. If we fail to implement these new technologies successfully, or if we are slower than our competitors at implementing new technologies, we may not be able to competitively offer products that our customers desire, which could harm our operating results.

If we do not properly manage new product development, our competitiveness and operating results may be negatively affected.

As advances in computer hardware and software are made, our customers have demanded a more diversified portfolio of products with new and additional features. In some cases, this demand results in investments in new products for a particular market that do not necessarily expand overall market opportunity, which may negatively affect our operating results.

In addition, the success of our new product introductions depends on a number of other factors, including

• difficulties faced in manufacturing ramp;

• implementing at an acceptable cost product features expected by our customers;

• market acceptance/qualification;

• effective management of inventory levels in line with anticipated product demand;

• quality problems or other defects in the early stages of new product introduction and problems with compatibility between our products and those of our customers that were not anticipated in the design of those products; and

• our ability to increase our software development capability.

Our business may suffer if we fail to successfully anticipate and manage issues associated with our product development.

If we fail to develop and introduce new products that are competitive against alternative storage technologies, our business may suffer.

Our success depends in part on our ability to develop and introduce new products in a timely manner in order to keep pace with technology advancements. Storage technologies like solid-state storage have successfully served mobility markets for products that cannot be serviced using hard drive technology. Advances in semiconductor technology have resulted in solid-state storage emerging as a technology that can be competitive with hard drives for high performance needs in advanced digital computing markets such as enterprise servers and storage. There can be no assurance that we will be successful in anticipating and developing new products for the PC and other storage markets in response to competing storage technologies. If our hard drive and solid state products fail to offer a superior value proposition to alternative storage products, we will be at a competitive disadvantage to companies using alternative technology and our business will suffer.

23

Our operations, and those of certain of our suppliers and customers, are concentrated in large, purpose-built facilities, subjecting us to substantial risk of damage or loss if operations at any of these facilities are disrupted.

As a result of our cost structure and strategy of vertical integration, we conduct our operations at large, high volume, purpose-built facilities in California and in Asia. The facilities of many of our customers, our suppliers and our customers’ suppliers are also concentrated in certain geographic locations in Asia and elsewhere. A localized health risk affecting our employees at these facilities or the staff of our or our customers’ other suppliers, such as the spread of a pandemic influenza, could impair the total volume of our products that we are able to manufacture or sell, which would result in substantial harm to our operating results. Similarly, a fire, flood, earthquake, tsunami or other disaster, condition or event such as political instability, civil unrest or a power outage that adversely affects any of these facilities, including access to or from these facilities by employees or logistics operators, would significantly affect our ability to manufacture or sell our products, which would result in a substantial loss of sales and revenue and a substantial harm to our operating results. For example, prior to the 2011 flooding in Thailand, all of our internal slider capacity and 60% of our hard drive manufacturing capacity was in Thailand. As a result of the flooding in Thailand, our facilities were inundated and temporarily shut down. During that period, our ability to manufacture hard drives was significantly constrained, adversely affecting our business, financial condition and results of operations. A significant event that impacts any of our manufacturing sites, or the sites of our customers or suppliers, could adversely affect our ability to manufacture or sell our products, and our business, financial condition and results of operations could suffer.

Manufacturing and marketing our products globally subjects us to numerous risks.

We are subject to risks associated with our global manufacturing operations and global marketing efforts, including:

• obtaining requisite governmental permits and approvals;

• currency exchange rate fluctuations or restrictions;

• political instability and civil unrest;

• limited transportation availability, delays, and extended time required for shipping, which risks may be compounded in periods of price declines;

• higher freight rates;

• labor challenges, including difficulties finding and retaining talent or responding to labor disputes or disruptions;

• trade restrictions or higher tariffs;

• copyright levies or similar fees or taxes imposed in European and other countries;

• exchange, currency and tax controls and reallocations;

• increasing labor and overhead costs; and

• loss or non-renewal of favorable tax treatment under agreements or treaties with foreign tax authorities.

Terrorist attacks may adversely affect our business and operating results.

The continued threat of terrorist activity and other acts of war or hostility have created uncertainty in the financial and insurance markets and have significantly increased the political, economic and social instability in some of the geographic areas in which we operate. Additionally, it is uncertain what impact the reactions to such acts by various governmental agencies and security regulators worldwide will have on shipping costs. Acts of terrorism, either domestically or abroad, could create further uncertainties and instability. To the extent this results in disruption or delays of our manufacturing capabilities or shipments of our products, our business, operating results and financial condition could be adversely affected.

24

Sudden disruptions to the availability of freight lanes could have an impact on our operations.

We generally ship our products to our customers, and receive shipments from our suppliers, via air, ocean or land freight. The sudden unavailability or disruption of cargo operations or freight lanes caused by, among other things, labor difficulties or disputes, severe weather patterns or other natural disasters, or political instability or civil unrest, could impact our operating results by impairing our ability to timely and efficiently deliver our products.

If we sustain system failures, cyber attacks to our systems or to our products or other data security breaches, we could suffer a loss of revenue and increased costs, exposure to significant liability, reputational harm and other serious negative consequences.

We are heavily dependent on our technology infrastructure, among other functions, to operate our factories, provide and sell our products and services, fulfill orders, manage inventory and bill, collect and make payments and we are subject to laws, rules and regulations in the U.S. and other countries relating to the collection, use and security of user data. Our systems are vulnerable to damage or interruption from natural disasters, power loss, telecommunication failures, cyber attacks such as 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 intentional or unintentional acts by employees. Computer programmers, hackers and others may be able to develop and deploy viruses, worms, and other malicious software programs or otherwise attack our products, to discover or exploit any security vulnerabilities or breach or compromise the security schemes of our products. In addition, sophisticated hardware and operating system software and applications that we produce or procure from third parties may contain defects in design or manufacture, including “bugs” and other problems that could unexpectedly interfere with the operation of the system.

The foregoing security problems could result in, among other consequences, loss or theft of our, our customers’ or our business partners’ intellectual property, proprietary business information or personally identifiable information. The costs to us to eliminate or address the foregoing security problems and security vulnerabilities before or after a cyber incident could be significant. Our remediation efforts may not be successful and could result in interruptions, delays or cessation of service and loss of existing or potential customers that may impede our sales, manufacturing, distribution, or other critical functions. We could lose existing or potential customers in connection with any actual or perceived security vulnerabilities in our products. In addition, breaches of our security measures and the unapproved dissemination of proprietary information or sensitive or confidential data or personal data or information about us, our customers or other third parties, could expose us, our customers, or other affected third parties to a risk of loss or misuse of this information, result in litigation, damage our brand and reputation, or otherwise harm our business, operating results and financial condition. Further, we rely on third-party data management providers whose possible security problems and security vulnerabilities may have similar effects on us.

If we fail to identify, manage, complete and integrate acquisitions, investment opportunities or other significant transactions, it may adversely affect our future results.

As part of our growth strategy, we have completed, and we may continue to pursue, acquisitions of, investment opportunities in, or other significant transactions with companies that are complementary to our business. For example, we completed the acquisition of VeloBit on July 9, 2013, sTec on September 12, 2013, and Virident on October 17, 2013. In order to pursue this part of our growth strategy successfully, we must continue to identify attractive acquisition or investment opportunities, successfully complete the transactions, some of which may be large and complex, and manage post-closing issues such as integration of the acquired company or employees. We may not be able to continue to identify or complete appealing acquisition or investment opportunities given the intense competition for these transactions. Even if we identify and complete suitable corporate transactions, we may not be able to successfully address any integration challenges in a timely manner, or at all. Failing to successfully integrate or realign our business to take advantage of efficiencies or reduce redundancies of an acquisition may result in not realizing all or any of the anticipated benefits of the acquisition. In addition, failing to achieve the financial model projections for an acquisition may result in the incurrence of impairment charges and other expenses, both of which could adversely impact our results of operations or financial condition.

Please also see the risk factors above for specific risks and uncertainties regarding our acquisition of HGST.

25

The loss of our key executive management, staff and skilled employees, the inability to hire and integrate new employees or decisions to realign our business could negatively impact our business prospects.

Our success depends upon the continued contributions of our key management, staff and skilled employees, many of whom would be extremely difficult to replace. Global competition for skilled employees in the data storage industry is intense and, as we attempt to move to a position of technology leadership in the storage industry, our business success becomes increasingly dependent on our ability to retain our key staff and skilled employees, to attract, integrate and retain new skilled employees and to make decisions to realign our business to take advantage of efficiencies or reduce redundancies. Volatility or lack of positive performance in our stock price and the overall markets may adversely affect our ability to retain key staff or skilled employees who have received equity compensation. Additionally, because a substantial portion of our key employees’ compensation is placed “at risk” and linked to the performance of our business, when our operating results are negatively impacted, we are at a competitive disadvantage for retaining and hiring key management, staff and skilled employees versus other companies that pay a relatively higher fixed salary. If we lose our existing key management, staff or skilled employees, or are unable to hire and integrate new key management, staff or skilled employees, or if we fail to implement succession plans for our key management or staff, our operating results would likely be harmed. Furthermore, if we do not realize the anticipated benefits of our intended realignment after we make decisions regarding our personnel and implement our realignment plans, our operating results could be adversely affected.

The nature of our industry and its reliance on intellectual property and other proprietary information subjects us and our suppliers and customers to the risk of significant litigation.

The data storage industry has been characterized by significant litigation. This includes litigation relating to patent and other intellectual property rights, product liability claims and other types of litigation. Litigation can be expensive, lengthy and disruptive to normal business operations. Moreover, the results of litigation are inherently uncertain and may result in adverse rulings or decisions. We may enter into settlements or be subject to judgments that may, individually or in the aggregate, have a material adverse effect on our business, financial condition or operating results. As disclosed in Part II, Item 8, Note 5 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K on November 18, 2011, a sole arbitrator ruled against us in an arbitration in Minnesota. The arbitration involves claims brought by Seagate Technology LLC against us and a now former employee, alleging misappropriation of confidential information and trade secrets. The arbitrator issued an interim award against us in the amount of $525 million plus pre-award interest. On January 23, 2012, the arbitrator issued a final award adding pre-award interest in the amount of $105.4 million, for a total award of $630.4 million. On January 23, 2012, we filed a petition in the District Court of Hennepin County, Minnesota to have the final arbitration award vacated, and a hearing on the petition was held on March 1, 2012. On October 12, 2012, the District Court of Hennepin County, Minnesota vacated, in full, the $630.4 million final arbitration award and ordered that a rehearing be held concerning certain trade secret claims before a new arbitrator. On October 30, 2012, Seagate initiated an appeal of the District Court’s decision with the Minnesota Court of Appeals. On July 22, 2013, the Minnesota Court of Appeals reversed the District Court’s decision and remanded for entry of an order and judgment confirming the arbitration award. We strongly disagree with the decision of the Court of Appeals and believe that the District Court’s decision was correct. On August 20, 2013, the Company filed a petition for review with the Minnesota Supreme Court and, on October 15, 2013, the Company was informed that the Minnesota Supreme Court granted the Company’s petition. The appeal before the Minnesota Supreme Court has been fully briefed, and oral argument was held on February 5, 2014.

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. In addition, our suppliers and customers are subject to similar risks of litigation, and a material, adverse ruling against a supplier or customer could negatively impact our business.

Our reliance on intellectual property and other proprietary information subjects us to the risk that these key ingredients of our business could be copied by competitors.

Our success depends, in significant part, on the proprietary nature of our technology, including non-patentable intellectual property such as our process technology. If a competitor is able to reproduce or otherwise capitalize on our technology despite the safeguards we have in place, it may be difficult, expensive or impossible for us to obtain necessary legal protection. Also, the laws of some foreign countries may not protect our intellectual property to the same extent as do U.S. laws. In addition to patent protection of intellectual property rights, we consider elements of our product designs and processes

26

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 could harm our operating results.

The costs of compliance with state, federal and international legal and regulatory requirements, such as environmental, labor, trade, health, safety and tax regulations, and customers’ standards of corporate citizenship could cause an increase in our operating costs.

We are subject to, and may become subject to additional, state, federal and international laws and regulations governing our environmental, labor, trade, health, safety and tax practices. These laws and regulations, particularly those applicable to our international operations, are or may be complex, extensive and subject to change. We will need to ensure that we and our component suppliers timely comply with such laws and regulations, which may result in an increase in our operating costs. Legislation has been, and may in the future be, enacted in locations where we manufacture or sell our products. In addition, climate change and financial reform legislation is a significant topic of discussion and has generated and may continue to generate federal, international or other regulatory responses in the near future. If we or our component suppliers fail to timely comply with applicable legislation, our customers may refuse to purchase our products or we may face increased operating costs as a result of taxes, fines or penalties, which would have a materially adverse effect on our business, financial condition and operating results.

In connection with our compliance with environmental laws and regulations, as well as our compliance with industry environmental initiatives, the standards of business conduct required by some of our customers, and our commitment to sound corporate citizenship in all aspects of our business, we could incur substantial compliance and operating costs and be subject to disruptions to our operations and logistics. In addition, if we were found to be in violation of these laws or noncompliant with these initiatives or standards of conduct, we could be subject to governmental fines, liability to our customers and damage to our reputation and corporate brand which could cause our financial condition or operating results to suffer.

Conflict minerals regulations may cause us to incur additional expenses and could limit the supply and increase the cost of certain components and metals contained in our products.

In August 2012, the SEC adopted new rules establishing diligence and disclosure requirements regarding the use and source of gold, tantalum, tin and tungsten, commonly referred to as 3TG or conflict minerals, that are necessary to the functionality or production of products manufactured or contracted to be manufactured by public companies. These new rules require us to determine and report annually whether such 3TG originated from the Democratic Republic of the Congo or an adjoining country, the first such report was due on June 2, 2014. These new rules could affect our ability to source components that contain 3TG, or 3TG generally, at acceptable prices and could impact the availability of such components or 3TG, since there may be only a limited number of suppliers of “conflict free” 3TG. Our customers, including our OEM customers, may require that our products contain only conflict free 3TG, and our revenues and margins may be harmed if we are unable to meet this requirement at a reasonable price, or at all, or are unable to pass through any increased costs associated with meeting this requirement. Additionally, we may suffer reputational harm with our customers and other stakeholders if our products are not conflict free or if we are unable to sufficiently verify the origins of the 3TG contained in our products through the due diligence procedures that we implement. We could incur significant costs to the extent that we are required to make changes to products, processes, or sources of supply due to the foregoing requirements or pressures. To the extent that proposed conflict minerals legislation is adopted by the European Commission or Canada, these risks could increase.

Violation of applicable laws, including labor or environmental laws, and certain other practices by our suppliers or customers could harm our business.

We expect our suppliers and customers to operate in compliance with applicable laws and regulations, including labor and environmental laws, and to otherwise meet our required standards of conduct. While our internal operating guidelines promote ethical business practices, we do not control our suppliers or customers or their labor or environmental practices. The violation of labor, environmental or other laws by any of our suppliers or customers, or divergence of a supplier’s or customer’s business practices from those generally accepted as ethical, could harm our business by:

• interrupting or otherwise disrupting the shipment of our product components;

• damaging our reputation;

• forcing us to find alternate component sources;

• reducing demand for our products (for example, through a consumer boycott); or

27

• exposing us to potential liability for our suppliers’ or customers’ wrongdoings.

Any decisions to reduce or discontinue paying cash dividends to our shareholders or repurchase shares of our common stock pursuant to our previously announced stock repurchase program could cause the market price for our common stock to decline.

Our payment of quarterly cash dividends and repurchase shares of our common stock pursuant to our stock purchase program will be subject to, among other things, our financial position and results of operations, available cash and cash flow, capital requirements, and other factors. Any reduction or discontinuance by us of the payment of quarterly cash dividends or repurchases of our common stock pursuant to our stock repurchase program could cause the market price of our common stock to decline. Moreover, in the event our payment of quarterly cash dividends or repurchases of shares of our common stock are reduced or discontinued, our failure or inability to resume paying cash dividends or repurchasing shares of our common stock at historical levels could result in a lower market valuation of our common stock.

Fluctuations in currency exchange rates as a result of our international operations may negatively affect our operating results.

Because we manufacture and sell our products abroad, our revenue, margins, operating costs and cash flows are impacted by fluctuations in foreign currency exchange rates. If the U.S. dollar exhibits sustained weakness against most foreign currencies, the U.S. dollar equivalents of unhedged manufacturing costs could increase because a significant portion of our production costs are foreign-currency denominated. Conversely, there would not be an offsetting impact to revenues since revenues are substantially U.S. dollar denominated. Additionally, we negotiate and procure some of our component requirements in U.S. dollars from non-U.S. based vendors. If the U.S. dollar weakens against other foreign currencies, some of our component suppliers may increase the price they charge for their components in order to maintain an equivalent profit margin. If this occurs, it would have a negative impact on our operating results.

Prices for our products are substantially U.S. dollar denominated even when sold to customers that are located outside the United States. Therefore, as a substantial portion of our sales are from countries outside the United States, fluctuations in currency exchanges rates, most notably the strengthening of the U.S. dollar against other foreign currencies, contribute to variations in sales of products in impacted jurisdictions and could adversely impact demand and revenue growth. In addition, currency variations can adversely affect margins on sales of our products in countries outside the United States.

We have attempted to manage the impact of foreign currency exchange rate changes by, among other things, entering into short-term, foreign exchange contracts. However, these contracts do not cover our full exposure and can be canceled by the counterparty if currency controls are put in place.

Increases in our customers’ credit risk could result in credit losses and term extensions under existing contracts with customers with credit losses could result in an increase in our operating costs.

Some of our OEM customers have adopted a subcontractor model that requires us to contract directly with companies, such as ODMs, that provide manufacturing and fulfillment services to our OEM customers. Because these subcontractors are generally not as well capitalized as our direct OEM customers, this subcontractor model exposes us to increased credit risks. Our agreements with our OEM customers may not permit us to increase our product prices to alleviate this increased credit risk. Additionally, as we attempt to expand our OEM and distribution channel sales into emerging economies such as Brazil, Russia, India and China, the customers with the most success in these regions may have relatively short operating histories, making it more difficult for us to accurately assess the associated credit risks. Our acquisition of HGST has also resulted in an increase to our customer credit risk given that we service many of the same customers. Any credit losses we may suffer as a result of these increased risks, or as a result of credit losses from any significant customer, especially in situations where there are term extensions under existing contracts with such customers, would increase our operating costs, which may negatively impact our operating results.

Our operating results fluctuate, sometimes significantly, from period to period due to many factors, which may result in a significant decline in our stock price.

Our quarterly operating results may be subject to significant fluctuations as a result of a number of other factors including:

• the timing of orders from and shipment of products to major customers;

• our product mix;

28

• changes in the prices of our products;

• manufacturing delays or interruptions;

• acceptance by customers of competing products in lieu of our products;

• variations in the cost of and lead times for components for our products;

• limited availability of components that we obtain from a single or a limited number of suppliers;

• seasonal and other fluctuations in demand for systems that use storage devices often due to technological advances; and

• availability and rates of transportation.

We often ship a high percentage of our total quarterly sales in the third month of the quarter, which makes it difficult for us to forecast our financial results before the end of the quarter. As a result of the above or other factors, our forecast of operating results for the quarter may differ materially from our actual financial results. If our results of operations fail to meet the expectations of analysts or investors, it could cause an immediate and significant decline in our stock price.

We have made and continue to make a number of estimates and assumptions relating to our consolidated financial reporting, and actual results may differ significantly from our estimates and assumptions.

We have made and continue to make a number of estimates and assumptions relating to our consolidated financial reporting. The highly technical nature of our products and the rapidly changing market conditions with which we deal means that actual results may differ significantly from our estimates and assumptions. These changes have impacted our financial results in the past and may continue to do so in the future. Key estimates and assumptions for us include:

• price protection adjustments and other sales promotions and allowances on products sold to retailers, resellers and distributors;

• inventory adjustments for write-down of inventories to lower of cost or market value (net realizable value);

• testing of goodwill and other long-lived assets for impairment;

• reserves for doubtful accounts;

• accruals for product returns;

• accruals for warranty costs related to product defects;

• accruals for litigation and other contingencies;

• liabilities for unrecognized tax benefits; and

• expensing of stock-based compensation.

The market price of our common stock is volatile.

The market price of our common stock has been, and may continue to be, volatile. Factors that may significantly affect the market price of our common stock include the following:

• actual or anticipated fluctuations in our operating results, including those resulting from the seasonality of our business;

• 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;

29

• strategic actions by us or competitors, such as acquisitions and restructurings;

• 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;

• proposed or adopted regulatory changes or developments or anticipated or pending investigations, proceedings or litigation that involve or affect us or our competitors;

• conditions and trends in the hard drive, solid state storage, 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;

• failure to meet analysts’ revenue or earnings estimates or changes in financial estimates or publication of research reports and recommendations by financial analysts relating specifically to us or the storage industry in general; and

• macroeconomic conditions that affect the market generally and, in particular, developments related to market conditions for our industry.

In addition, the stock market is subject to fluctuations in the stock prices and trading volumes that affect the market prices of the stock of public companies, including us. These broad market fluctuations have adversely affected and may continue to adversely affect the market price of shares of our common stock. For example, expectations concerning 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.

The resale of shares of common stock issued to Hitachi in connection with our acquisition of HGST could adversely affect the market price of our common stock.

On March 8, 2012, as partial consideration for our acquisition of HGST, we issued 25 million shares of our common stock to Hitachi. On November 6, 2013, Hitachi completed a secondary offering of 12.5 million of these shares. We are required by the terms of an Investor Rights Agreement we entered into with Hitachi to file a Form S-3 registration statement with the Securities and Exchange Commission to register the resale by Hitachi of the remaining shares of common stock by a date designated by Hitachi in consultation with the Company and after reasonable prior notice to the Company. Sales of these shares of our common stock in the public market, or the perception that these sales may occur, could adversely affect the market price of our common stock.

Our cash balances and investment portfolio are subject to various risks, any of which could adversely impact our financial position.

Given the international footprint of our business, we have both domestic and international cash balances and investments. We maintain an investment portfolio of various holdings, security types, and maturities. These investments are subject to general credit, liquidity, market, political, sovereign and interest rate risks, which may be exacerbated by unusual events that affect global financial markets. A material part of our investment portfolio consists of U.S. government securities and bank deposits. If global credit and equity markets experience prolonged periods of decline, or if there is a downgrade of the U.S. government credit rating due to an actual or threatened default on government debt, our investment portfolio may be adversely impacted and we could determine that our investments may experience an other-than-temporary decline in fair value, requiring impairment charges that could adversely affect our financial results. A failure of any of these financial institutions in which deposits exceed FDIC limits could also have an adverse impact on our financial position.

If our internal controls are found to be ineffective, our stock price may be adversely affected.

Our most recent evaluation resulted in our conclusion that as of June 27, 2014, in compliance with Section 404 of the Sarbanes-Oxley Act of 2002, our internal control over financial reporting was effective. If our internal control over financial

30

reporting is found to be ineffective or if we identify a material weakness in our financial reporting in future periods, investors may lose confidence in the reliability of our financial statements, which may adversely affect our stock price.

Restrictive covenants in our credit agreement could restrict current and future operations or limit our flexibility to take certain actions.

Our credit agreement includes covenants relating to our financial performance and financial position. In addition, our credit agreement restricts our ability to take other actions with respect to our current and future operations, including our ability to incur certain additional indebtedness or consolidate, merge or sell assets. Our ability to meet these restrictive covenants may be affected by events that could be beyond our control, and a breach of these restrictive covenants could result in an event of default under the credit agreement, which, if not cured or waived, could result in the indebtedness becoming immediately due and payable and could result in material adverse consequences that negatively impact our business.

From time to time we may become subject to income tax audits or similar proceedings, and as a result we may incur additional costs and expenses or owe additional taxes, interest and penalties that may negatively impact our operating results.

We are subject to income taxes in the United States and certain foreign jurisdictions, and our determination of our tax liability is subject to review by applicable domestic and foreign tax authorities. For example, as we have previously disclosed, we are under examination by the Internal Revenue Service for certain fiscal years and in connection with that examination, we received Revenue Agent Reports seeking certain adjustments to income as disclosed in Part II, Item 8, Note 9 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. Although we believe our tax positions are properly supported, the final timing and resolution of any tax examinations are subject to significant uncertainty and could result in our having to pay amounts to the applicable tax authority in order to resolve examination of our tax positions, which could result in an increase or decrease of our current estimate of unrecognized tax benefits and may negatively impact our financial position, results of operations or cash flows.

We are subject to risks associated with loss or non-renewal of favorable tax treatment under agreements or treaties with foreign tax authorities.

Portions of our operations are subject to a reduced tax rate or are free of tax under various tax holidays that expire in whole or in part from time to time. Many of these holidays may be extended when certain conditions are met, or terminated if certain conditions are not met. If the tax holidays are not extended, or if we fail to satisfy the conditions of the reduced tax rate, then our effective tax rate could increase in the future. In addition, any actions by us to repatriate non-U.S. earnings for which we have not previously provided for U.S. taxes may impact our effective tax rate.

On October 17, 2013, we acquired Virident, a provider of server-side flash storage solutions for virtualization, database, cloud computing and webscale applications. Virident was fully integrated into our HGST subsidiary and became our wholly owned indirect subsidiary. The purchase price of the acquisition was approximately $613 million, consisting of $598 million which was funded with available cash and $15 million related to the fair value of stock options assumed. The acquisition furthered HGST's strategy to address the rapidly changing needs of enterprise customers by delivering intelligent storage solutions that maximize application performance by leveraging the tightly coupled server, storage and network resources of today’s converged datacenter infrastructures. The acquisition of Virident did not have a material impact on our consolidated financial statements for fiscal 2014.

Acquisition of sTec, Inc. (“sTec”)

On September 12, 2013, we completed the acquisition of sTec, a provider of enterprise SSDs. As a result of the acquisition, sTec was fully integrated into our HGST subsidiary and became our wholly owned indirect subsidiary. The acquisition augmented HGST's existing solid-state storage capabilities. The purchase price of the acquisition was approximately $336 million, consisting of $325 million which was funded with available cash and $11 million related to the fair value of stock options and restricted stock units ("RSUs") assumed. The acquisition of sTec did not have a material impact on our consolidated financial statements for fiscal 2014.

Acquisition of VeloBit, Inc. ("VeloBit")

On July 9, 2013, we acquired VeloBit, a privately held provider of high-performance storage I/O optimization software. As a result of the acquisition, VeloBit was fully integrated into our HGST subsidiary and became our wholly owned indirect subsidiary. The acquisition built on HGST's strategy to enhance the overall value of datacenter storage by integrating HGST SSDs with software. The acquisition did not have a material impact on our consolidated financial statements for fiscal 2014.

Hitachi Global Storage Technologies Holdings Pte. Ltd. (“HGST”) Acquisition

On March 8, 2012, we completed the acquisition of Viviti Technologies Ltd., known until shortly before the acquisition as HGST, from Hitachi, Ltd. (“Hitachi”). The acquisition is intended over time, and subject to compliance with the regulatory conditions discussed below under “Maintenance of Competitive Requirement,” to result in a more efficient and innovative customer-focused storage company. We do not expect to achieve significant operating expense synergies while the regulatory conditions are in effect. The aggregate purchase price of the HGST acquisition was approximately $4.7 billion, consisting of $4.6 billion funded with $3.7 billion of existing cash and cash from new debt as well as 25 million newly issued shares of our common stock with a fair value of $877 million, and $102 million related to the fair value of stock options, RSUs and cash-settled stock appreciation rights ("SARs") assumed.

Toshiba Transactions

In connection with the regulatory approval process of the HGST acquisition, we announced on May 15, 2012 that we had closed a transaction with Toshiba Corporation (“Toshiba”) to divest certain 3.5-inch hard drive assets and to purchase Toshiba Storage Device (Thailand) Company Limited (“TSDT”), a wholly owned subsidiary of Toshiba that manufactured hard drives prior to the Thailand flooding in 2011. The net impact of these two transactions was immaterial to our consolidated financial statements. In August 2013, we received a $45 million insurance recovery related to the Thailand flooding for the facilities acquired in connection with the acquisition of TSDT.

Maintenance of Competitive Requirement

In connection with the regulatory approval process of the HGST acquisition, we agreed to certain conditions required by the Ministry of Commerce of the People’s Republic of China (“MOFCOM”), including adopting measures to maintain HGST as an independent competitor until MOFCOM agrees otherwise (with the minimum period being two years from the closing date of March 8, 2012). In March 2014, we submitted an application to MOFCOM requesting that the regulatory restrictions be lifted. At this time, we are awaiting MOFCOM’s response to our application.

For additional information on our acquisition, see Part II, Item 8, Note 15 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

Results of Operations

Fiscal 2014 Overview

In accordance with accounting principles generally accepted in the United States (“U.S. GAAP”), operating results for Virident, sTec, VeloBit and HGST, which were acquired on October 17, 2013, September 12, 2013, July 9, 2013 and March 8, 2012, respectively, are included in our operating results only after the respective dates of acquisition.

In 2014, our net revenue decreased by 1% to $15.1 billion on hard drive shipments of 249 million units as compared to $15.4 billion on shipments of 242 million units in 2013. In 2014, 53% of our net revenue was derived from our enterprise applications, branded products and CE products, as compared to 50% in 2013. Hard drive average selling price (“ASP”) decreased to $58 in 2014 from $61 in 2013. Gross profit as a percentage of revenue increased to 28.8% in 2014 from 28.4% in 2013. Operating income increased from $1.3 billion in 2013 to $1.8 billion in 2014. Operating income in 2014 included $95 million of employee termination, asset impairment and other charges and $52 million of charges related to an arbitration award as compared to $138 million and $681 million for the same charges in 2013, respectively. As a percentage of net revenue, operating income was 11.8% in 2014 compared to 8.2% in 2013. Net income in 2014 was $1.6 billion, or $6.68 per diluted share, compared to $980 million, or $3.98 per diluted share, in 2013.

For the September quarter, we expect overall hard drive industry shipments to increase from the June quarter’s 138 million units primarily as a result of seasonality. We expect our revenue in the September quarter to increase slightly as a result of seasonality and an additional week in our first fiscal quarter of 2015 to realign our fiscal quarter ends.

Fiscal Year 2014 Compared to Fiscal Year 2013

Net Revenue. Net revenue was $15.1 billion for 2014, a decrease of 1% from 2013. ASPs were $58 for 2014, a decrease of $3 from 2013. These decreases were primarily due to modest price declines and a change in product mix, partially offset by an increase in unit shipments. Total hard drive shipments in 2014increased to 249 million units as compared to 242 million units for the prior year primarily due to strength in our consumer electronics solutions, including gaming consoles.

Changes in revenue by geography and channel generally reflect normal fluctuations in market demand and competitive dynamics.

Consistent with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For each of 2014 and 2013, these programs represented 8% of gross revenues. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product.

Gross Profit. Gross profit for 2014 was $4.4 billion, a decrease of $3 million from the prior year. Gross profit as a percentage of net revenue increased to 28.8% in 2014 as compared to 28.4% in 2013. The increase in gross profit as a percentage of net revenue was primarily driven by higher volumes in 2014 as compared to 2013 as well as a continued focus on operational excellence.

Operating Expenses. Total research and development (“R&D”) expense and selling, general and administrative (“SG&A”) expense increased to 16.0% of net revenue in 2014 compared to 14.8% in 2013. R&D expense was $1.7 billion in 2014, an increase of $89 million, or 6%, over the prior year. This increase was primarily due to the inclusion of Virident and sTec's R&D expenses from the dates of acquisition and the continued investment in product development. As a percentage of net revenue, R&D expense increased to 11.0% in 2014 compared to 10.2% in 2013. SG&A expense was $761 million in 2014, an increase of $55 million, or 8%, as compared to 2013. This increase in SG&A expense was primarily due to the inclusion of Virident and sTec's SG&A expenses from the dates of acquisition and the expansion of sales and marketing to support new products and growing markets, partially offset by a $65 million gain on flood-related insurance recovery. SG&A expense as a percentage of net revenue increased to 5.0% in 2014 compared to 4.6% in 2013.

During 2014 and 2013, we recorded $52 million and $681 million, respectively, for charges related to an arbitration award for claims brought against us and a now former employee by Seagate Technology LLC (“Seagate”), alleging misappropriation of confidential information and trade secrets. For further detail see the “Arbitration Award” section below.

39

During 2014, we recorded $95 million of employee termination, asset impairment and other charges. These charges consisted of $27 million of employee termination benefits, $62 million of asset impairment charges and $6 million of other charges. During 2013, we recorded $138 million of employee termination, asset impairment and other charges. These charges consisted of $109 million of employee termination benefits, $14 million of asset impairment charges and $15 million of other charges.

Other Income (Expense). Other expense, net was $39 million in 2014 compared to $44 million in 2013. Interest and other income increased from $11 million in 2013 to $17 million in 2014 primarily due to a $3 million gain on the sale of our auction-rate securities in 2014 and a higher average daily invested cash balance for the period. Interest and other expense increased from $55 million in 2013 to $56 million in 2014, primarily due to a $4 million write-off of debt issuance costs associated with lenders that extinguished or reduced their participation in our newly entered into Credit Agreement (as defined below), offset by lower variable interest rates on our average debt balance in 2014.

Income Tax Provision. Income tax expense was $135 million in 2014 as compared to $242 million in 2013. Tax expense as a percentage of income before taxes was 7.7% in 2014 compared to 19.8% in 2013. Our income tax provision for 2013 also reflects a tax benefit of $37 million as a result of the retroactive extension of the U.S. Federal research and experimentation tax credit (“R&D credit”) that was signed into law on January 2, 2013 as part of the American Taxpayer Relief Act of 2012. The R&D credit, which had previously expired on December 31, 2011, was extended through December 31, 2013. In addition, we recorded an $88 million charge to reduce our previously recognized California deferred tax assets in fiscal 2013 as a result of the enactment of California Proposition 39. California Proposition 39, which was approved by California voters on November 6, 2012, affects California state income tax apportionment for most multi-state taxpayers for tax years beginning on or after January 1, 2013. This proposition reduces our future income apportioned to California, making it less likely for us to realize certain California deferred tax assets. The differences between the effective tax rate and the U.S. Federal statutory rate are primarily due to tax holidays in Malaysia, the Philippines, Singapore and Thailand that expire at various dates from 2015 through 2025 and the current year generation of income tax credits.

As of June 27, 2014, we had a recorded liability for unrecognized tax benefits of $300 million. We recognized a net increase of $60 million in our liability for unrecognized tax benefits during 2014. Interest and penalties recognized on such amounts were not material.

The Internal Revenue Service (“IRS”) previously completed its field examination of our federal income tax returns for fiscal years 2006 and 2007 and issued Revenue Agent Reports that proposed adjustments to income before income taxes of approximately $970 million primarily related to transfer pricing and intercompany payable balances. We disagreed with the proposed adjustments and filed a protest with the IRS Appeals Office. In June 2013, we reached an agreement with the IRS to resolve the transfer pricing issue. This agreement resulted in a decrease in the amount of net operating loss and tax credits realized, but did not have an impact on our consolidated statements of income. The proposed adjustment relating to intercompany payable balances for fiscal years 2006 and 2007 will be addressed in conjunction with the IRS’s examination of our fiscal years 2008 and 2009, which commenced in January 2012. In addition, in January 2012, the IRS commenced an examination of the 2007 fiscal period ended September 5, 2007 of Komag, Incorporated ("Komag"), which was acquired by us on September 5, 2007. In February 2013, the IRS commenced an examination of calendar years 2010 and 2011 of HGST, which was acquired by us on March 8, 2012.

We believe that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in our tax audits are resolved in a manner not consistent with management's expectations, we could be required to adjust our provision for income taxes in the period such resolution occurs. As of June 27, 2014, it was not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of our liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of our tax returns.

Arbitration Award

As disclosed below in Part II, Item 8, Note 5 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K, on November 18, 2011, a sole arbitrator ruled against us in an arbitration in Minnesota. The arbitration involves claims brought by Seagate against us and a now former employee, alleging misappropriation of confidential information and trade secrets. The arbitrator issued an interim award against us in the amount of $525 million plus pre-award interest. On January 23, 2012, the arbitrator issued a final award adding pre-award interest in the amount of $105.4 million, for a total award of $630.4 million. On January 23, 2012, we filed a petition in the District Court of Hennepin County, Minnesota to have the final arbitration award vacated, and a hearing on the petition to vacate was held on March 1, 2012. On October 12, 2012, the District Court of Hennepin County, Minnesota vacated, in full, the $630.4 million final arbitration award

40

and ordered that a rehearing be held concerning certain trade secret claims before a new arbitrator. On October 30, 2012, Seagate initiated an appeal of the District Court's decision with the Minnesota Court of Appeals. On July 22, 2013, the Minnesota Court of Appeals reversed the District Court's decision and remanded for entry of an order and judgment confirming the arbitration award. We strongly disagree with the decision of the Court of Appeals and believe that the District Court’s decision was correct. On August 20, 2013, we filed a petition for review with the Minnesota Supreme Court and, on October 15, 2013, we were informed that the Minnesota Supreme Court granted our petition. The appeal before the Minnesota Supreme Court was fully briefed, and oral argument was held on February 5, 2014. We will continue to vigorously defend ourselves in this matter. In light of uncertainties with respect to this matter, we recorded an accrual of $681 million for this matter in fiscal 2013. This amount was in addition to the $25 million previously accrued in fiscal 2011. In 2014, we recorded an additional $52 million for interest related to the arbitration award. As a result, the total amount accrued of $758 million represents the amount of the final arbitration award, plus interest accrued on the initial arbitration award at the statutory rate of 10% from January 24, 2012 through June 27, 2014.

Fiscal Year 2013 Compared to Fiscal Year 2012

Net Revenue. Net revenue was $15.4 billion for 2013, an increase of 23% from 2012. Total hard drive shipments in 2013 increased to 242 million units as compared to 202 million units for the prior year. The increase in net revenue resulted primarily from the contribution of a full year of HGST operations, partially offset by continued soft industry demand as well as a $1 decrease in ASP from $62 to $61.

Changes in revenue by geography and channel generally reflect normal fluctuations in market demand and competitive dynamics.

Consistent with standard industry practice, we have sales incentive and marketing programs that provide customers with price protection and other incentives or reimbursements that are recorded as a reduction to gross revenue. For 2013, these programs represented 8% of gross revenues compared to 6% in 2012. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product.

Gross Profit. Gross profit for 2013 was $4.4 billion, an increase of $725 million, or 20%, from the prior year. Gross profit as a percentage of net revenue decreased to 28.4% in 2013 from 29.2% in 2012. This percentage decrease was primarily due to a decrease in ASP as well as $101 million of incremental amortization, reflecting a full year of amortization for intangibles related to the acquisition of HGST.

Operating Expenses. Total R&D expense and SG&A expense increased to 14.8% of net revenue in 2013 compared to 12.6% in 2012. R&D expense was $1.6 billion in 2013, an increase of $517 million, or 49%, over the prior year. This increase was primarily due to the inclusion of HGST’s R&D expense for the full year period as well as continued investment in product development to support new programs. As a percentage of net revenue, R&D expense increased to 10.2% in 2013 compared to 8.5% in 2012. SG&A expense was $706 million in 2013, an increase of $188 million, or 36%, as compared to 2012. This increase in SG&A expense was primarily due to the inclusion of a full year of HGST’s SG&A expense and amortization of intangibles related to the acquisition of HGST, partially offset by the inclusion of acquisition-related expenses in the prior-year period. SG&A expense as a percentage of net revenue increased to 4.6% in 2013 compared to 4.2% in 2012.

During 2013, we recorded a $681 million charge related to an arbitration award for claims brought against us and a now former employee by Seagate, alleging misappropriation of confidential information and trade secrets.

During 2013, we recorded $138 million of employee termination benefits and other charges. These charges consisted of $109 million of employee termination benefits, $14 million of asset impairment charges and $15 million of other charges. During 2012, we recorded $56 million of asset impairment charges, $16 million of contract termination and other exit costs and $8 million of employee termination benefits. In addition, during 2012, we recorded $214 million of net charges related to the flooding in Thailand, including $119 million of fixed asset impairments, $61 million of recovery charges, $28 million of write-downs of damaged inventory and $27 million in wage continuation during the shutdown period of our facilities, partially offset by $21 million of insurance recoveries and other cost reimbursements.

Other Income (Expense). Other expense, net was $44 million in 2013 compared to $14 million in 2012. Interest and other income decreased slightly from $12 million in 2012 to $11 million in 2013 primarily due to a lower average daily invested cash balance for the period. Interest and other expense increased from $26 million in 2012 to $55 million in 2013, primarily due to interest on a higher debt balance since the acquisition of HGST.

Income Tax Provision. Income tax expense was $242 million in 2013 as compared to $145 million in 2012. Tax expense as a percentage of income before taxes was 19.8% in 2013 compared to 8.3% in 2012. Our income tax provision for 2013 also reflects a tax benefit of $37 million as a result of the retroactive extension of the R&D credit that was signed into law

41

on January 2, 2013 as part of the American Taxpayer Relief Act of 2012. The R&D credit, which had previously expired on December 31, 2011, was extended through December 31, 2013. In addition, we recorded an $88 million charge to reduce our previously recognized California deferred tax assets in fiscal 2013 as a result of the enactment of California Proposition 39. The differences between the effective tax rate and the U.S. Federal statutory rate are primarily due to tax holidays in Malaysia, the Philippines, Singapore and Thailand that expire at various dates from 2014 through 2025, the current year generation of income tax credits and the effect of California Proposition 39.

As of June 28, 2013, we had a recorded liability for unrecognized tax benefits of approximately $240 million. We recognized a net decrease of $40 million in our liability for unrecognized tax benefits during 2013. Interest and penalties recognized on such amounts were not material.

Liquidity and Capital Resources

We ended 2014 with total cash and cash equivalents of $4.8 billion, an increase of $495 million from June 28, 2013. The following table summarizes our statements of cash flows for the three years ended June 27, 2014 (in millions):

	Years Ended
	June 27, 2014			June 28, 2013			June 29, 2012
Net cash flow provided by (used in):
Operating activities	$	2,816		$	3,119		$	3,067
Investing activities	(1,936		)	(970		)	(4,167		)
Financing activities	(385		)	(1,048		)	819
Effect of exchange rate changes on cash	—			—			(1		)
Net increase (decrease) in cash and cash equivalents	$	495		$	1,101		$	(282	)

Our investment policy is to manage our investment portfolio to preserve principal and liquidity while maximizing return through the full investment of available funds. On January 9, 2014, the outstanding balance on the existing credit facility entered into on March 8, 2012 (the "Prior Credit Facility") was repaid, the Prior Credit Facility was terminated, and we, along with Western Digital Technologies, Inc. ("WDT") and WDI entered into a new credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the "Credit Agreement"). The Credit Agreement provides for $4.0 billion of unsecured loan facilities consisting of a $2.5 billion term loan facility to WDT, and a $1.5 billion revolving credit facility to WDT and WDI (the "Borrowers"). Subject to certain conditions, a Borrower may also elect to expand the credit facilities by, or obtain incremental term loans of, up to $1.0 billion if existing or new lenders provide additional term or revolving commitments. For additional information on the Prior Credit Facility and the Credit Agreement, See Part II, Item 8, Note 3 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K. We believe our current cash, cash equivalents and cash generated from operations as well as our available credit facilities will be sufficient to meet our working capital, debt, dividend, stock repurchase and capital expenditure needs for at least the next twelve months. Our ability to sustain our working capital position is subject to a number of risks that we discuss in Item 1A of this Annual Report on Form 10-K.

A total of $3.5 billion and $2.8 billion of our cash and cash equivalents was held outside of the United States at June 27, 2014 and June 28, 2013, respectively. Substantially all of the amounts held outside of the United States are intended to be indefinitely reinvested in foreign operations. If we are required to pay the arbitration award described in the section “Arbitration Award” above, the award would be paid from one of our foreign subsidiaries using cash and cash equivalents held outside of the United States. On September 13, 2012, our Board of Directors approved a capital allocation plan which includes repurchases of our common stock and the adoption of a quarterly cash dividend policy. Our current plans do not anticipate that we will need funds generated from foreign operations to fund our domestic operations or capital allocation plan. In the event funds from foreign operations are needed in the United States, any repatriation could result in the accrual and payment of additional U.S. income tax.

Operating Activities

Net cash provided by operating activities was $2.8 billion in 2014 as compared to $3.1 billion in both 2013 and 2012. 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 used in working capital changes was $234 million for 2014 as compared to net cash provided by working capital changes of $715 million and $324 million for 2013 and 2012, respectively.

42

Our working capital requirements primarily depend on the effective management of our cash conversion cycle, which measures how quickly we can convert our products into cash through sales. The average quarterly cash conversion cycles for the three years ended 2014 were as follows:

	Years Ended
	June 27, 2014		June 28, 2013		June 29, 2012
Days sales outstanding	48		43		49
Days in inventory	41		39		37
Days payables outstanding	(67	)	(66	)	(83	)
Cash conversion cycle	22		16		3

For 2014, our average days sales outstanding (“DSOs”) increased by 5 days, days in inventory (“DIOs”) increased by 2 days, and days payables outstanding (“DPOs”) increased by 1 day. Changes in average DSOs and DIOs are generally related to linearity of shipments and the timing of inventory builds, respectively. Changes in DPOs are generally related to production volume and the timing of purchases during the period. In 2012, the higher DPOs were primarily due to the impact of including HGST’s accounts payable balances as of June 29, 2012, but only including HGST’s cost of sales from the date of acquisition. From time to time, we modify the timing of payments to our vendors. We make modifications primarily to manage our vendor relationships and to manage our cash flows, including our cash balances. Generally, we make the payment modifications through negotiations with our vendors or by granting to, or receiving from, our vendors’ payment term accommodations.

Investing Activities

Net cash used in investing activities for 2014 was $1.9 billion as compared to $970 million for 2013 and $4.2 billion for 2012. During 2014, cash used in investing activities consisted primarily of $823 million related to acquisitions, net of cash acquired, $628 million of capital expenditures, $561 million related to the purchase of investments and $4 million of other investing activities, net, offset by $72 million of proceeds from the sales and maturities of investments. During 2013, cash used in investing activities consisted primarily of $952 million of capital expenditures and $17 million related to the purchase of investments. Capital expenditures in 2014 and 2012 consisted of charges related to the normal replacement of existing assets. Capital expenditures in 2013 primarily consisted of flood recovery and increased capacity for our broadening and growing product portfolio. During 2012, cash used in investing activities consisted of $3.5 billion, net of cash acquired, used for the acquisitions, $76 million of proceeds related to the sale of equipment, and capital expenditures of $717 million.

Our cash equivalents are invested in highly liquid money market funds that are invested in U.S. Treasury securities and U.S. Government Agency securities. In addition, we invest directly in U.S. Treasury securities, U.S. Government Agency securities, commercial paper, bank acceptances and certificates of deposit. During 2014, we sold our entire $14 million portfolio of auction-rate securities, resulting in a gain of $3 million which was included in interest and other income in the consolidated statements of income.

Financing Activities

Net cash used in financing activities was $385 million for 2014 and $1.0 billion for 2013 as compared to net cash provided by financing activities of $819 million for 2012. Net cash used in financing activities for 2014 consisted of $2.5 billion of debt proceeds related to the term loan facility under the Credit Agreement, net of issuance costs, $500 million of debt proceeds related to the revolving credit facility under the Prior Credit Facility and a net $215 million provided by employee stock plans, offset by $2.5 billion used to repay the Prior Credit Facility and make principal payments on the Credit Agreement, as well as $816 million used to repurchase shares of our common stock and $259 million used to pay dividends on our common stock. Net cash used in financing activities for 2013 consisted of $842 million used to repurchase shares of our common stock, $181 million used to pay dividends on our common stock and $230 million used to repay long-term debt, partially offset by a net $205 million provided by employee stock plans. Net cash provided by financing activities for 2012 consisted of the $2.8 billion of proceeds borrowed under the Credit Facility in connection with the acquisition of HGST, net of issuance costs, and a net $141 million provided by employee stock plans, partially offset by $604 million used to repurchase stock and $1.5 billion used to repay our outstanding debt as well as debt assumed in the acquisition of HGST.

Off-Balance Sheet Arrangements

Other than facility lease commitments incurred in the normal course of business and certain indemnification provisions (see “Contractual Obligations and Commitments” below), we do not have any off-balance sheet financing

43

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.

* Included within our consolidated balance sheet

Long-Term Debt

On March 8, 2012, we, in our capacity as the parent entity and guarantor, and the Borrowers, entered into the Prior Credit Facility. The Prior Credit Facility provided for $2.8 billion of unsecured loan facilities, consisting of a $2.3 billion term loan facility and a $500 million revolving credit facility. On January 9, 2014, the outstanding balance on the Prior Credit Facility was repaid, the Prior Credit Facility was terminated, and the new Credit Agreement was entered into.

As of June 27, 2014, no amounts were outstanding under the revolving credit facility of the Credit Agreement and the term loan facility had an outstanding balance of $2.4 billion and a variable interest rate of 1.7%. We are required to make quarterly principal payments on the term loan facility totaling $125 million in fiscal 2015, $156 million in fiscal 2016, $219 million in fiscal 2017, $250 million in fiscal 2018 and the remaining balance of $1.7 billion in fiscal 2019. For additional information, see Part II, Item 8, Note 3 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

The Credit Agreement requires the Company 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 Agreement contains customary covenants, including covenants that limit or restrict the Company’s and its subsidiaries’ ability to incur liens, incur indebtedness, make certain restricted payments, merge or consolidate and enter into certain speculative hedging arrangements, and customary events of default. As of June 27, 2014, the Company was in compliance with all covenants.

Purchase Orders

In the normal course of business, we enter into purchase orders with suppliers for the purchase of 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, containing 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

44

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 commitments.

Foreign Exchange Contracts

We purchase short-term, foreign 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 a description of our current foreign exchange contract commitments and Part II, Item 8, Notes 1 and 12 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.

Indemnifications

In the ordinary course of business, we may provide indemnifications of varying scope and terms to customers, vendors, lessors, business partners and other parties with respect to certain matters, including, but not limited to, losses arising out of our breach of 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.

Unrecognized Tax Benefits

As of June 27, 2014, the cash portion of our total recorded liability for unrecognized tax benefits was $246 million. We estimate the timing of the future payments of these liabilities to be within the next one to eight years. See Part II, Item 8, Note 9 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K for information regarding our total tax liability for unrecognized tax benefits.

Stock Repurchase Program

Since May 18, 2012, our Board of Directors has authorized $3.0 billion for the repurchase of our common stock and the extension of our stock repurchase program until September 13, 2017. We repurchased 10.3 million shares of our common stock for a total cost of $816 million in 2014. The remaining amount available to be purchased under our stock repurchase program as of June 27, 2014 was $1.2 billion. Subsequent to June 27, 2014 and through August 14, 2014, we repurchased an additional 2.0 million shares of our common stock for a total cost of $203 million. We may continue to repurchase our common stock as we deem appropriate and market conditions allow. Repurchases under our stock repurchase program may be made in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. We expect stock repurchases to be funded principally by operating cash flows and borrowings under our Credit Agreement.

Cash Dividend Policy

On September 13, 2012, we announced that our Board of Directors had authorized the adoption of a quarterly cash dividend policy. Under the cash dividend policy, holders of our common stock receive dividends when and as declared by our Board of Directors. In 2014, we declared aggregate cash dividends of $1.25 per share of our common stock, totaling $295 million, of which $201 million was paid during 2014. On August 5, 2014, we announced that our Board of Directors declared a cash dividend of $0.40 per share of our common stock to shareholders of record as of October 3, 2014, which will be paid on October 15, 2014. We may modify, suspend or cancel our cash dividend policy in any manner and at any time. See Part II, Item 5 included in this Annual Report on Form 10-K for further information.

Critical Accounting Policies and Estimates

We have prepared the accompanying consolidated financial statements in accordance with U.S. GAAP. The preparation of the financial statements requires the use of judgments and estimates that affect the reported amounts of revenues,

45

expenses, assets, liabilities and shareholders’ equity. We have adopted accounting policies and practices that are generally accepted in the industry in which we operate. We believe the following are our most critical accounting policies that affect significant areas and involve judgment and estimates made by us. If these estimates differ significantly from actual results, the impact to the consolidated financial statements may be material.

Revenue and Accounts Receivable

In accordance with standard industry practice, we provide distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions, and we provide resellers and OEMs with other sales incentive programs. At the time we recognize revenue to resellers and OEMs, we record a reduction of revenue for estimated price protection until the resellers sell such inventory to their customers and we also record a reduction of revenue for the other programs in effect. We base these adjustments on several factors including anticipated price decreases during the reseller holding period, resellers’ sell-through and inventory levels, estimated amounts to be reimbursed to qualifying customers, historical pricing information and customer claim processing. If customer demand for hard drives or market conditions differs from our expectations, our operating results could be materially affected. We also have programs under which we reimburse qualified distributors and retailers for certain marketing expenditures, which are recorded as a reduction of revenue. These amounts generally vary according to several factors including industry conditions, seasonal demand, competitor actions, channel mix and overall availability of product. Generally, total sales incentive and marketing programs range from 7% to 11% of gross revenues per quarter. For 2014, sales incentive and marketing programs were 8% of gross revenues. Changes in future customer demand and market conditions may require us to adjust our incentive programs as a percentage of gross revenue from the current range. Adjustments to revenues due to changes in accruals for these programs related to revenues reported in prior periods have averaged 0.7% of quarterly gross revenue since the first quarter of fiscal 2012. Customer sales incentive and marketing programs are recorded as a reduction of revenue.

We record an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency, disputes or other collection issues. In addition, we routinely analyze the different receivable aging categories and establish reserves based on a combination of past due receivables and expected future losses based primarily on our historical levels of bad debt losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if our overall loss history changes significantly, an adjustment in our allowance for doubtful accounts would be required, which could materially affect operating results.

We establish provisions against revenue and cost of revenue for sales returns in the same period that the related revenue is recognized. We base these provisions on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.

Warranty

We record an accrual for estimated warranty costs when revenue is recognized. We generally warrant our products for a period of one to five years. Our warranty provision considers estimated product failure rates and trends, estimated replacement costs, estimated repair costs which include scrap costs, and estimated costs for customer compensatory claims related to product quality issues, if any. We use a statistical warranty tracking model to help prepare our estimates and assist us in exercising judgment in determining the underlying estimates. Our statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Our judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base our warranty estimates. We review our warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross profit and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from our estimates, our future results of operations could be materially affected. For a summary of historical changes in estimates related to pre-existing warranty provisions, refer to Part II, Item 8, Note 4 in the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K.

Inventories

We value inventories at the lower of cost (first-in, first-out and weighted average methods) or net realizable value. We use the first-in, first-out (“FIFO”) method to value the cost of the majority of our inventories, while we use the weighted-average method to value precious metal inventories. Weighted-average cost is calculated based upon the cost of precious metals at the time they are received by us. We have determined that it is not practicable to assign specific costs to individual units of precious metals and, as such, we relieve our precious metals inventory based on the weighted-average cost of the inventory at

46

the time the inventory is used in production. The weighted-average method of valuing precious metals does not materially differ from a FIFO method. We record inventory write-downs for the valuation of inventory at the lower of cost or net realizable value by analyzing market conditions and estimates of future sales prices as compared to inventory costs and inventory balances.

We evaluate inventory balances for excess quantities and obsolescence on a regular basis by analyzing estimated demand, inventory on hand, sales levels and other information, and reduce inventory balances to net realizable value for excess and obsolete inventory based on this analysis. Unanticipated changes in technology or customer demand could result in a decrease in demand for one or more of our products, which may require a write down of inventory that could materially affect operating results.

Litigation and Other Contingencies

When we become aware of a claim or potential claim, we assess the likelihood of any loss or exposure. We disclose information regarding each material claim where the likelihood of a loss contingency is probable or reasonably possible. If a loss contingency is probable and the amount of the loss can be reasonably estimated, we record an accrual for the loss. In such cases, there may be an exposure to potential loss in excess of the amount accrued. Where a loss is not probable but is reasonably possible or where a loss in excess of the amount accrued is reasonably possible, we disclose an estimate of the amount of the loss or range of possible losses for the claim if a reasonable estimate can be made, unless the amount of such reasonably possible losses is not material to our financial position, results of operations or cash flows. The ability to predict the ultimate outcome of such matters involves judgments, estimates and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates. Refer to Part II, Item 8, Note 5 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.

Income Taxes

We account for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of our assets and liabilities and expected benefits of utilizing net operating loss and tax credit carryforwards. We record a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each 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 a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in our provision for income taxes. The actual liability for unrealized tax benefits in any such contingency may be materially different from our estimates, which could result in the need to record additional liabilities for unrecognized tax benefits or potentially adjust previously-recorded liabilities for unrealized tax benefits and materially affect our operating results.

47

Stock-based Compensation

We account for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options and cash-settled stock appreciation rights (“SARs”) granted are estimated using a binomial model, and the fair values of all Employee Stock Purchase Plan purchase rights are estimated using the Black-Scholes-Merton option-pricing model. We account for SARs as liability awards based upon our intention to settle such awards in cash. The SARs liability is recognized for that portion of fair value for the service period rendered at the reporting date. The share-based liability is remeasured at each reporting date through the requisite service period. Both the binomial and the Black-Scholes-Merton models require the input of highly subjective assumptions. We are required to use judgment in estimating the amount of stock-based awards that are expected to be forfeited. If actual forfeitures differ significantly from the original estimate, stock-based compensation expense and our results of operations could be materially affected.

Goodwill and Other Long-Lived Assets

The fair value of assets acquired and liabilities assumed in a business acquisition are recognized at the acquisition date, with amounts exceeding the fair values being recognized as goodwill. Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. We perform our annual impairment test as of the first day of our fiscal fourth quarter. We either use qualitative factors to determine whether goodwill is more likely than not impaired or we perform a two-step approach to quantify impairment. If we conclude from the qualitative assessment that goodwill is more likely than not impaired, we are required to follow a two-step approach to quantify the impairment. We are required to use judgment when applying the goodwill impairment test, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. In addition, the estimates used to determine the fair value of each reporting unit may change based on results of operations, macroeconomic conditions or other factors. Changes in these estimates could materially affect our assessment of the fair value and goodwill impairment for each reporting unit.

Other intangible assets consist primarily of technology acquired in business combinations and in-process research and development. In-process research and development is not amortized until the point at which it reaches technological feasibility. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that it may be impaired. Acquired intangibles are amortized on a straight-line basis over their respective estimated useful lives. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If impairment is indicated, the impairment is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets.

Recent Accounting Pronouncements

For a description of recently issued and adopted accounting pronouncements, including the respective dates of adoption and expected effects on our results of operations and financial condition, refer to Part II, Item 8, Note 1 of the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K, which is incorporated by reference in response to this item.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

Disclosure About Foreign Currency Risk

Although the majority of our transactions are in U.S. dollars, some transactions are based in various foreign currencies. We purchase short-term, foreign exchange contracts to hedge the impact of foreign currency exchange fluctuations on certain underlying assets, revenue, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedge transactions is to minimize the impact of foreign currency fluctuations on our results of operations. The contract maturity dates do not exceed 12 months. We do not purchase foreign exchange contracts for trading purposes. See Part II, Item 8, Notes 1 and 12 in the Notes to Consolidated Financial Statements, included in this Annual Report on Form 10-K.

As of June 27, 2014, we had outstanding the following purchased foreign exchange contracts (in millions, except weighted average contract rate):

Disclosure About Other Market Risks

Variable Interest Rate Risk

On January 9, 2014, the outstanding balance on the Prior Credit Facility was repaid, the Prior Credit Facility was terminated, and we entered into the new Credit Agreement.

Borrowings under the Credit Agreement bear interest at a rate equal to, at the option of the applicable Borrower, either (a) a customary London interbank offered rate (a “Eurodollar Rate”) or (b) a customary base rate (a “Base Rate”), in each case plus an applicable margin. The applicable margins range from 1.25% to 2.00% with respect to Eurodollar Rate borrowings and 0.25% to 1.00% with respect to Base Rate borrowings. The Borrowers are also required to pay a commitment fee for the unused portion of the revolving credit facility, which ranges from 0.175% to 0.300% per annum. The applicable margins for borrowings and the commitment fee ranges are determined based upon a leverage ratio of us and our subsidiaries calculated on a consolidated basis. A one percent increase in the variable rate of interest on the term loan and revolving credit facility would increase interest expense by approximately $24 million annually. For additional information, see Part II, Item 8, Note 3 in the Notes to Consolidated Financial Statements included in this Annual Report on Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Western Digital Corporation:

We have audited the accompanying consolidated balance sheets of Western Digital Corporation and subsidiaries as of June 27, 2014 and June 28, 2013, and the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the years in the three-year period ended June 27, 2014. 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 June 27, 2014 and June 28, 2013, and the results of their operations and their cash flows for each of the years in the three-year period ended June 27, 2014, 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 June 27, 2014, based on criteria established in Internal Control — Integrated Framework (1992) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO), and our report dated August 14, 2014, expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Board of Directors and Shareholders

Western Digital Corporation:

We have audited Western Digital Corporation and subsidiaries’ internal control over financial reporting as of June 27, 2014, based on criteria established in Internal Control — Integrated Framework (1992) 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 June 27, 2014, based on criteria established in Internal Control — Integrated Framework (1992) 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 June 27, 2014 and June 28, 2013, the related consolidated statements of income, comprehensive income, shareholders’ equity, and cash flows for each of the years in the three-year period ended June 27, 2014, and the related financial statement schedule, and our report dated August 14, 2014, expressed an unqualified opinion on those consolidated financial statements and financial statement schedule.

WESTERN DIGITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1. Organization and Summary of Significant Accounting Policies

Western Digital Corporation (the “Company” or “Western Digital”) is a leading developer, manufacturer and provider of data storage solutions that enable consumers, businesses, governments and other organizations to create, manage, experience and preserve digital content. The Company's product portfolio includes hard disk drives (“HDDs”) and solid-state drives ("SSDs"). HDDs are the Company's principal products and are today’s primary storage medium for digital content, with the use of solid-state storage products growing rapidly. The Company's products are marketed under the HGST, WD and G-Technology brand names.  The Company currently operate our global business through two independent subsidiaries due to regulatory requirements—HGST and WD.

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 2014, 2013 and 2012 fiscal years which ended on June 27, 2014, June 28, 2013 and June 29, 2012, respectively, consisted of 52 weeks each.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In fiscal 2014 and fiscal 2013, the accounts for all foreign subsidiaries have been remeasured using the U.S. dollar as the functional currency. In fiscal 2012, the accounts for all foreign subsidiaries, except for one Japanese subsidiary in which Yen was the functional currency, have been remeasured using the U.S. dollar as the functional currency. Gains or losses resulting from remeasurement or translation of these accounts from local currencies into U.S. dollars were immaterial to the consolidated financial statements.

The Company acquired Virident Systems, Inc. ("Virident") on October 17, 2013, sTec, Inc. (“sTec”) on September 12, 2013, and VeloBit, Inc. ("VeloBit") on July 9, 2013. In addition, on March 8, 2012, the Company completed its acquisition of all of the issued and paid-up share capital of Viviti Technologies Ltd., known until shortly before acquisition as Hitachi Global Storage Technologies Holdings Pte. Ltd. (“HGST”), from Hitachi, Ltd. (“Hitachi”). These acquisitions are further described in Note 15 below. In connection with the acquisitions, Virident, sTec, VeloBit and HGST became indirect wholly-owned subsidiaries of the Company. The results of operations of Virident, sTec, VeloBit and HGST since the respective dates of acquisition are included in the consolidated financial statements.

Cash and Cash Equivalents

The Company’s cash equivalents represent highly liquid investments in money market funds, which are invested in U.S. Treasury securities and U.S. Government agency securities as well as direct investments in bank acceptances with original maturities when purchased of three months or less. Cash equivalents are carried at cost, which approximates fair value.

Investments

The Company's investments in U.S. Treasury securities, U.S. Government agency securities, commercial paper and certificates of deposit with original maturities at purchase of more than three months. These investments are classified as available-for-sale securities and included within short-term investments and other non-current assets in the consolidated balance sheets. Available-for-sale securities are stated at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss), which is a component of shareholders' equity. The Company evaluates the available-for sale securities in an unrealized loss position for other-than-temporary impairment. The amortized cost of available-for-sale securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest and other income and other in the consolidated statements of income. In addition, realized gains and losses are included in total other expense, net in the consolidated statements of income.

In addition, the Company enters into certain strategic investments for the promotion of business and strategic objectives. These strategic investments are recorded at cost within other non-current assets in the consolidated balance sheets and are

58

WESTERN DIGITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

periodically analyzed to determine whether or not there are indicators of impairment. Lastly, the Company’s investments included auction-rate securities which were all sold during 2014. The Company's auction rate securities were classified as available-for-sale securities and carried at fair value within other non-current assets in the consolidated balance sheets.

Fair Value of Financial Instruments

The carrying amounts of cash equivalents, accounts receivable, investments, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities or, in the case of investments, these are recorded using appropriate market information. The carrying amount of debt approximates fair value because of its variable interest rate.

Concentration of Credit Risk

The Company sells its products to computer manufacturers, resellers and retailers throughout the world. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. The Company maintains allowances for potential credit losses, and such losses have historically been within management’s expectations. At any given point in time, the total amount outstanding from any one of a number of its customers may be individually significant to the Company’s financial results. At June 27, 2014 and June 28, 2013, the Company had two customers that accounted for 29% of the Company's net accounts receivable. At June 27, 2014 and June 28, 2013, the Company had reserves for potential credit losses of $11 million and $9 million, respectively, and net accounts receivable of $2.0 billion and $1.8 billion at each date, 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.

Inventories

The Company values inventories at the lower of cost (first-in, first out and weighted average methods) or net realizable value. The first-in, first-out (“FIFO”) method is used to value the cost of the majority of the Company’s inventories, while the weighted-average method is used to value precious metal inventories. Weighted-average cost is calculated based upon the cost of precious metals at the time they are received by the Company. The Company has determined that it is not practicable to assign specific costs to individual units of precious metals and, as such, precious metals are relieved from inventory based on the weighted-average cost of the inventory at the time the inventory is used in production. The weighted average method of valuing precious metals does not materially differ from a FIFO method. As of June 27, 2014 and June 28, 2013, 92% and 91%, 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 the Company’s products, which may require a write down of inventory that could materially affect operating results.

Property, Plant and Equipment

The cost of property, plant and equipment is depreciated over the estimated useful lives of the respective assets. The Company’s buildings are depreciated over periods ranging from fifteen to thirty years. The majority of the Company’s equipment is depreciated over periods of two to seven years. Depreciation is computed on a straight-line basis. Leasehold improvements are amortized over the lesser of the estimated useful lives of the assets or the related lease terms.

Goodwill and Other Long-Lived Assets

The fair value of assets acquired and liabilities assumed in a business acquisition are recognized at the acquisition date, with amounts exceeding the fair values being recognized as goodwill. Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. The Company performs its annual impairment test as of the first day of its fiscal fourth quarter. The Company either uses qualitative factors to determine whether goodwill is more likely than not impaired or performs a two-step approach to quantify impairment. If the Company concludes from the qualitative assessment that goodwill is more likely than not impaired,

59

WESTERN DIGITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

it is required to follow a two-step approach to quantify the impairment. The Company is required to use judgment when applying the goodwill impairment test, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. In addition, the estimates used to determine the fair value of each reporting unit may change based on results of operations, macroeconomic conditions or other factors. Changes in these estimates could materially affect the Company’s assessment of the fair value and goodwill impairment for each reporting unit. The Company did not record any impairment of goodwill during 2014, 2013, or 2012.

Other intangible assets consist primarily of technology acquired in business combinations and in-process research and development. In-process research and development is not amortized until the point at which it reaches technological feasibility. Instead, it is instead tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that it may be impaired. Acquired intangibles are amortized on a straight-line basis over their respective estimated useful lives. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If impairment is indicated, the impairment is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company recorded impairments to certain long-lived assets in 2014, 2013 and 2012. See Notes 13 and 17.

Revenue and Accounts Receivable

Revenue is recognized when the title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, delivery has occurred, or services have been rendered, the sales price is fixed or determinable and collectability is reasonably assured. The Company establishes provisions against revenue and cost of revenue for estimated sales returns in the same period that the related revenue is recognized based on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.

In accordance with standard industry practice, the Company provides distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions, and the Company provides resellers and OEMs with other sales incentive programs. At the time the Company recognizes revenue to resellers and OEMs, a reduction of revenue is recorded for estimated price protection until the resellers sell such inventory to their customers and the Company also records a reduction of revenue for the other programs in effect. The Company bases these adjustments on several factors including anticipated price decreases during the reseller holding period, reseller’s sell-through and inventory levels, estimated amounts to be reimbursed to qualifying customers, historical pricing information and customer claim processing. If customer demand for the Company's products or market conditions differ from the Company’s expectations, the Company’s operating results could be materially affected. The Company also has programs under which it reimburses qualified distributors and retailers for certain marketing expenditures, which are recorded as a reduction of revenue. Customer sales incentive and marketing programs are recorded as a reduction of revenue.

The Company records an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency, disputes or other collection issues. In addition, the Company routinely analyzes the different receivable aging categories and establishes reserves based on a combination of past due receivables and expected future losses based primarily on its historical levels of bad debt losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if the Company’s overall loss history changes significantly, an adjustment in the Company’s allowance for doubtful accounts would be required, which could materially affect operating results.

Warranty

The Company records an accrual for estimated warranty costs when revenue is recognized. The Company generally warrants its products for a period of one to five years. The warranty provision considers estimated product failure rates and trends, estimated replacement costs, estimated repair costs which include scrap costs, and estimated costs for customer compensatory claims related to product quality issues, if any. A statistical warranty tracking model is used to help prepare estimates and assist the Company in exercising judgment in determining the underlying estimates. The statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Management’s judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base warranty estimates. Management reviews the warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross profit and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return

60

WESTERN DIGITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

trends, costs to repair returned products or costs of customer compensatory claims differ significantly from estimates, future results of operations could be materially affected.

Litigation and Other Contingencies

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

Advertising Expense

Advertising costs are expensed as incurred. Selling, general and administrative expenses of the Company included advertising costs of $60 million, $61 million and $30 million in 2014, 2013 and 2012, respectively.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of assets and liabilities and expected benefits of utilizing net operating loss (“NOL”) and tax credit carryforwards. The Company records a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each period, the Company evaluates the need for a valuation allowance for its deferred tax assets and adjusts the valuation allowance so that the Company records net deferred tax assets only to the extent that it has concluded it is more likely than not that these deferred tax assets will be realized.

The Company recognizes liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. The actual liability for unrealized tax benefits 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, and may materially affect the Company’s operating results.

Income per Common Share

The Company computes basic income per common share using net income and the weighted average number of common shares outstanding during the period. Diluted income per common share is computed using net income and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include certain dilutive outstanding employee stock options, rights to purchase shares of common stock under the Company’s Employee Stock Purchase Plan (“ESPP”) and restricted stock unit awards (“RSUs”).

_______________

* For purposes of computing diluted income per common share, certain potentially dilutive securities have been excluded from the calculation because their effect would have been anti-dilutive.

Stock-based Compensation

The Company accounts for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options and cash-settled stock appreciation rights (“SARs”) granted are estimated using a binomial option-pricing model, and the fair values of all ESPP purchase rights are estimated using the Black-Scholes-Merton option-pricing model. The Company accounts for SARs as liability awards based upon management’s intention to settle such awards in cash. The SARs liability is recognized for that portion of fair value for the service period rendered at the reporting date. The share-based liability is remeasured at each reporting date through the requisite service period. Both the binomial and the Black-Scholes-Merton option-pricing models require the input of highly subjective assumptions. The Company is required to use judgment in estimating the amount of stock-based awards that are expected to be forfeited. If actual forfeitures differ significantly from the original estimate, stock-based compensation expense and the results of operations could be materially affected.

Other Comprehensive Income (Loss)

Other comprehensive income (loss) refers to revenue, expenses, gains and losses that are recorded as an element of shareholders’ equity but are excluded from net income. The Company’s other comprehensive income (loss) is comprised of unrealized gains and losses on foreign exchange contracts, unrealized gains and losses on the Company's available-for-sale securities, foreign currency translation gains and losses and actuarial gains and losses related to pensions. The income tax impact on components of other comprehensive income is immaterial for all periods presented.

Although the majority of the Company’s transactions are in U.S. dollars, some transactions are based in various foreign currencies. The Company purchases short-term, foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Company’s results of operations. These contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Company does not purchase foreign exchange contracts for trading purposes. The Company had foreign exchange contracts with commercial banks for British Pound Sterling, Euro, Japanese Yen, Malaysian Ringgit, Philippine Peso, Singapore Dollar and Thai Baht, which were designated as either cash flow or fair value hedges and had an aggregate notional amount of $1.5 billion and $2.0 billion at June 27, 2014 and June 28, 2013, respectively.

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 and presented within cash flow from operations. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts entered into for manufacturing-related activities are reported in cost of revenue and presented within cash flow from operations. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. The Company determined the ineffectiveness associated with its cash flow hedges to be immaterial for all years presented.

A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of operating expenses. All fair value hedges were determined to be effective. The fair value and the changes in fair value on these contracts were immaterial to the consolidated financial statements for all years presented. See Notes 10 and 12 for additional disclosures related to foreign exchange contracts.

Pensions and Other Postretirement Benefit Plans

The Company has defined benefit pension plans and other postretirement plans covering certain employees in various countries. The benefits are based on the employees’ years of service and compensation. The plans are funded in conformity with the funding requirements of applicable government authorities. The Company amortizes unrecognized actuarial gains and

losses and prior service costs on a straight-line basis over the remaining estimated average service life of the participants. The measurement date for the plans is the Company’s fiscal year-end. The Company recognizes the funded status of its defined benefit pension and postretirement plans in the consolidated balance sheets, with changes in the funded status recognized through accumulated other comprehensive income (loss) in the year in which such changes occur. See Note 14 for additional disclosures related to the Company’s pension and other postretirement benefit plans.

Use of Estimates

Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The Company adopted this pronouncement in the first quarter of fiscal 2014. Since ASU 2013-02 related only to the presentation and disclosure of information, it did not have a material effect on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" ("ASU 2013-11"). The new standard requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The new standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2013, which for the Company is the first quarter of fiscal 2015. The Company does not expect the adoption of ASU 2013-11 to have a material impact on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"), which amends the guidance in former Accounting Standards Codification ("ASC") Topic 605, "Revenue Recognition", to provide a single, comprehensive revenue recognition model for all contracts with customers. The new standard requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in amounts that reflect the consideration to which an entity expects to be entitled in exchange for those goods or services. The new standard also requires entities to enhance disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new standard allows for either a full retrospective or a modified retrospective transition method and is effective for fiscal years beginning after December 15, 2016, which for the Company is the first quarter of fiscal 2018. The Company has not yet selected a transition method and is currently evaluating the impact ASU 2014-09 will have on its consolidated financial statements and related disclosures.

In April 2014, the FASB issued ASU 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"), which amends the criteria for determining which disposals can be presented as discontinued operations and enhances related disclosure requirements. Under the new guidance, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has or may have a major effect on an entity’s operations and financial results. The new standard is effective for fiscal years beginning after December 15, 2014, which for the Company is the first quarter of fiscal 2016. The Company does not expect the adoption of ASU 2014-08 to have a material impact on its consolidated financial statements.

On March 8, 2012 (the “HGST Closing Date”), the Company, in its capacity as the parent entity and guarantor, Western Digital Technologies, Inc. (“WDT”), a wholly owned subsidiary of the Company, and Western Digital Ireland, Ltd. (“WDI”), an indirect wholly owned subsidiary of the Company, entered into a five-year credit agreement (the “Prior Credit Facility”) with Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer, and certain other participating lenders. The Prior Credit Facility provided for $2.8 billion of unsecured loan facilities consisting of a $2.3 billion term loan facility and a $500 million revolving credit facility. On January 9, 2014, WDI used existing cash to repay the outstanding term loan balance of $1.8 billion under the Prior Credit Facility, and the Company, WDT and WDI, entered into a new credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the "Credit Agreement"); WDT paid the outstanding revolving credit facility balance of $500 million under the Prior Credit Facility; and the Company terminated the Prior Credit Facility. In connection with the repayment of the Prior Credit Facility, $4 million of debt issuance costs associated with lenders that extinguished or reduced their participation in the Credit Agreement were written off in fiscal 2014, and are included within interest and other expense in the consolidated statements of income. The Credit Agreement provides for $4.0 billion of unsecured loan facilities consisting of a $2.5 billion term loan facility to WDT and a $1.5 billion revolving credit facility to WDT and WDI (the “Borrowers”). The revolving credit facility includes a $100 million sublimit for letters of credit and a $50 million sublimit for swing line loans. Subject to certain conditions, a Borrower may elect to expand the credit facilities by, or obtain incremental term loans of, up to $1.0 billion if existing or new lenders provide additional term or revolving commitments. The loans under the Credit Agreement have a five-year term. The obligations of the Borrowers under the Credit Agreement are guaranteed by the Company and its material domestic subsidiaries, and the obligations of WDI under the Credit Agreement are also guaranteed by WDT.

The term loans and the revolving credit loans may be prepaid in whole or in part at any time without premium or penalty, subject to certain conditions. As of June 27, 2014, no amounts were outstanding under the revolving credit facility and the term loan facility had a variable interest rate of 1.7% and a remaining, outstanding balance of $2.4 billion. The Company is required to make quarterly principal payments on the term loan facility totaling $125 million in fiscal 2015, $156 million in fiscal 2016, $219 million in fiscal 2017, $250 million in fiscal 2018 and the remaining balance of $1.7 billion in fiscal 2019.

The Credit Agreement requires the Company 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 Agreement contains customary covenants, including covenants that limit or restrict the Company’s and its subsidiaries’ ability to incur liens, incur indebtedness, make certain restricted payments, merge or consolidate and enter into certain speculative hedging arrangements, and customary events of default. As of June 27, 2014, the Company was in compliance with all covenants.

Note 5. Legal Proceedings

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

Solely for purposes of this footnote, “WD” refers to Western Digital Corporation or one or more of its subsidiaries excluding HGST prior to the HGST Closing Date. HGST refers to Hitachi Global Storage Technologies Holdings Pte. Ltd. or one or more of its subsidiaries as of the HGST Closing Date, and “the Company” refers to Western Digital Corporation and all of its subsidiaries on a consolidated basis including HGST.

Intellectual Property Litigation

On June 20, 2008, plaintiff Convolve, Inc. (“Convolve”) filed a complaint in the Eastern District of Texas against WD, HGST, and one other company alleging infringement of U.S. Patent Nos. 6,314,473 and 4,916,635. The complaint sought unspecified monetary damages and injunctive relief. On October 10, 2008, Convolve amended its complaint to allege infringement of only the ‘473 patent. The ‘473 patent allegedly relates to interface technology to select between certain modes of a disk drive’s operations relating to speed and noise. A trial in the matter began on July 18, 2011 and concluded on July 26, 2011 with a verdict against WD and HGST in an amount that is not material to the Company’s financial position, results of operations or cash flows, for which the Company previously recorded an accrual. WD and HGST have filed post-trial motions challenging the verdict. On January 17, 2014, the Court denied the Company’s motion for judgment as a matter of law on invalidity. On May 20, 2014, the Court ordered supplemental briefing related to post-trial motions related to infringement. Convolve and the Company filed their supplemental briefs on May 30, 2014 and June 6, 2014, respectively. Additional post-trial motions are pending, and the Company will evaluate its options for appeal after the Court rules on the remaining post-trial motions. The Company intends to continue to defend itself vigorously in this matter.

On December 7, 2009, plaintiff Nazomi Communications (“Nazomi”) filed a complaint in the Eastern District of Texas against WD and seven other companies alleging infringement of U.S. Patent Nos. 7,080,362 and 7,225,436. Nazomi dismissed the Eastern District of Texas suit after filing a similar complaint in the Central District of California on February 8, 2010. The case was subsequently transferred to the Northern District of California on October 14, 2010. The complaint seeks injunctive relief and unspecified monetary damages, fees and costs. The asserted patents allegedly relate to processor cores capable of Java hardware acceleration. In August 2012, the Court dismissed WD on summary judgment for non-infringement. Nazomi filed a notice of appeal on January 16, 2013. The Federal Circuit heard oral argument on the appeal on November 4, 2013 and affirmed the Court's grant of summary judgment of non-infringement on January 10, 2014. Because Nazomi did not file a petition for a writ of certiorari with the Supreme Court during the requisite time period, this matter is now closed.

On August 1, 2011, plaintiff Guzik Technical Enterprises (“Guzik”) filed a complaint in the Northern District of California against WD and various of its subsidiaries alleging infringement of U.S. Patent Nos. 6,023,145 and 6,785,085, breach of contract and misappropriation of trade secrets. The complaint seeks injunctive relief and unspecified monetary damages, fees and costs. The patents asserted by Guzik allegedly relate to devices used to test hard disk drive heads and media. On November 30, 2013, WD entered into a settlement agreement for an amount that is not material to the Company’s financial position, results of operations or cash flows, for which the Company recorded an accrual in the three months ended December 27, 2013. Guzik is disputing the enforceability of the agreement and on December 27, 2013, WD filed a motion to enforce the agreement. The Court heard oral argument on WD’s motion on January 31, 2014. The Court granted WD’s motion to enforce the settlement agreement on March 21, 2014. On April 14, 2014, Guzik filed a Notice of Appeal to the Federal Circuit. On June

17, 2014, Guzik filed its opening appellate brief. The Company filed its appellate brief on August 14, 2014. WD intends to continue to defend itself vigorously in this matter.

On July 9, 2012, Siemens Aktiengesellschaft (“Siemens”) filed a complaint in German court against WD, Western Digital GmbH, and Digital River International, S.a.r.l. alleging patent infringement of European patent no. EP 674769, which claims an artificial antiferromagnetic (AAF) (aka, synthetic antiferromagnetic) structure for magneto-resistive sensors. On March 14-15, 2013, Western Digital GmbH filed a response of non-infringement and also filed a separate nullity action. Siemens separately served WD on July 15, 2013. The patent expired on December 16, 2013 and, on March 10, 2014, Siemens withdrew its motion for injunctive relief. On February 5, 2014, the Company filed a submission in support of its nullity action. On March 25, 2014, Siemens served an extension of the complaint including WDT as a defendant. On March 28, 2014, Siemens filed its response to WD’s noninfringement submission. On June 27, 2014, WDT filed its response to the extension of the complaint. On or around July 14, 2014, Siemens filed a response to the Company’s nullity action. On July 18, 2014, the Company filed two expert opinions in support of its nullity action. Siemens has until September 5, 2014 to respond to WDT’s response to the extension of the complaint. WD’s deadline to make its last noninfringement submission is September 26, 2014. The oral hearing on infringement is scheduled for October 2, 2014. The oral hearing on the nullity action to challenge the validity of the patent is scheduled for February 3, 2015. WD intends to defend itself vigorously in this matter.

On September 5, 2013, plaintiff Lake Cherokee Hard Drive Technologies, LLC (“Lake Cherokee”) filed a complaint in the Eastern District of Texas against: Marvell Asia PTE, Ltd., Samsung Semiconductor, Inc., Seagate Tech. LLC, Seagate Tech. Int’l., Toshiba Corp., Toshiba Am. Elec. Components, Toshiba Am. Inf. Sys., Inc., Toshiba Am. Inf. Equip. (Philippines), Inc., and WDT alleging infringement of US Patent Nos. 5,844,738 and 5,978,162. Lake Cherokee alleges that WDT’s hard disk drive products that contain Marvell read channel systems-on-a-chip (SOCs) infringe its ’738 and ’162 patents. The complaint seeks unspecified monetary damages, fees and costs. On April 3, 2014, Lake Cherokee and Marvell Semiconductor, Inc. (“MSI”) engaged in mediation which resulted in a settlement-in-principle on April 8, 2014. On April 21, 2014, Lake Cherokee and MSI filed a motion to stay deadlines while the parties finalized a settlement agreement. In this motion, Lake Cherokee and MSI represented to the Court that the settlement between Lake Cherokee and MSI will result in a with-prejudice dismissal of Lake Cherokee’s claims against each of the defendants, including WDT, with respect to their sale or use of Marvell chips. On April 23, 2014, the Court granted a stay of deadlines. On June 6, 2014, Lake Cherokee and MSI participated in an arbitration hearing as to the remaining settlement agreement disputes. WDT intends to defend itself vigorously in this matter.

On September 25, 2013, plaintiff Lake Cherokee filed a complaint in the Eastern District of Texas against: Marvell Semiconductor, Inc., Marvell Asia PTE, Ltd., Dell Inc., and WDT alleging infringement of US Patent No. 5,583,706. Lake Cherokee alleges that WDT’s hard disk drive products that contain Marvell read channel systems-on-a-chip (SOCs) infringe its ’706 patent. The complaint seeks an injunction, unspecified monetary damages, fees and costs. On April 3, 2014, Lake Cherokee and MSI engaged in mediation which resulted in a settlement-in-principle on April 8, 2014. On April 21, 2014, Lake Cherokee and MSI filed a motion to stay deadlines while the parties finalized a settlement agreement. In this motion, Lake Cherokee and MSI represented to the Court that the settlement between Lake Cherokee and MSI will result in a with-prejudice dismissal of Lake Cherokee’s claims against each of the defendants, including WDT, with respect to their sale or use of Marvell chips. On April 23, 2014, the Court granted a stay of deadlines. On June 6, 2014, Lake Cherokee and MSI participated in an arbitration hearing as to the remaining settlement agreement disputes. WDT intends to defend itself vigorously in this matter.

On March 24, 2014, plaintiff Steven F. Reiber (“Reiber”) filed a complaint in the Eastern District of California against the Company, alleging infringement of U.S. Patent Nos. 7,124,927 and 7,389,905. Reiber alleges that the Company’s actions of making, using, distributing, offering for sale and selling in the United States and importing into the United States HDD heads, head gimbal assemblies, and head stack assemblies infringe the claims of the two patents at issue. The complaint seeks an injunction, unspecified monetary damages, fees and costs. Pursuant to the parties' stipulations, the Court has extended the deadline for the Company to respond to the Complaint to September 8, 2014, and set the parties' status conference for October 30, 2014. The Company intends to defend itself vigorously in this matter.

Seagate Matter

On October 4, 2006, plaintiff Seagate Technology LLC (“Seagate”) filed an action in the District Court of Hennepin County, Minnesota, naming as defendants WD and one of its now former employees previously employed by Seagate. The complaint in the action alleged claims based on supposed misappropriation of trade secrets and sought injunctive relief and unspecified monetary damages, fees and costs. On June 19, 2007, WD’s former employee filed a demand for arbitration with the American Arbitration Association. A motion to stay the litigation as against all defendants and to compel arbitration of all Seagate’s claims was granted on September 19, 2007. On September 23, 2010, Seagate filed a motion to amend its claims and add allegations based on the supposed misappropriation of additional confidential information, and the arbitrator granted Seagate’s motion. The arbitration hearing commenced on May 23, 2011 and concluded on July 11, 2011.

On November 18, 2011, the sole arbitrator ruled in favor of WD in connection with five of the eight alleged trade secrets at issue, based on evidence that such trade secrets were known publicly at the time the former employee joined WD. Based on a determination that the employee had fabricated evidence, the arbitrator then concluded that WD had to know of the fabrications. As a sanction, the arbitrator precluded any evidence or defense by WD disputing the validity, misappropriation, or use of the three remaining alleged trade secrets by WD, and entered judgment in favor of Seagate with respect to such trade secrets. Using an unjust enrichment theory of damages, the arbitrator issued an interim award against WD in the amount of $525 million plus pre-award interest at the Minnesota statutory rate of 10% per year. In his decision with respect to these three trade secrets, the arbitrator did not question the relevance, veracity or credibility of any of WD’s ten expert and fact witnesses (other than WD’s former employee), nor the authenticity of any other evidence WD presented. On January 23, 2012, the arbitrator issued a final award adding pre-award interest in the amount of $105.4 million for a total final award of $630.4 million. On January 23, 2012, WD filed a petition in the District Court of Hennepin County, Minnesota to have the final arbitration award vacated. A hearing on the petition to vacate was held on March 1, 2012.

On October 12, 2012, the District Court of Hennepin County, Minnesota vacated, in full, the $630.4 million final arbitration award. Specifically, the Court confirmed the arbitration award with respect to each of the five trade secret claims that WD and the former employee had won at the arbitration and vacated the arbitration award with respect to the three trade secret claims that WD and the former employee had lost at the arbitration. The Court ordered that a rehearing be held concerning those three alleged trade secret claims before a new arbitrator.

On October 30, 2012, Seagate initiated an appeal of the Court’s decision with the Minnesota Court of Appeals. On July 22, 2013, the Minnesota Court of Appeals reversed the District Court’s decision and remanded for entry of an order and judgment confirming the arbitration award. The Company strongly disagrees with the decision of the Court of Appeals and believes that the District Court’s decision was correct. On August 20, 2013, the Company filed a petition for review with the Minnesota Supreme Court and, on October 15, 2013, the Company was informed that the Minnesota Supreme Court granted the Company’s petition. The appeal before the Minnesota Supreme Court was fully briefed, and oral argument was held on February 5, 2014. The Company will continue to vigorously defend itself in this matter. In light of uncertainties with respect to this matter, the Company recorded an accrual of $681 million for this matter in its financial statements in the fourth quarter of fiscal 2013 and recorded additional interest totaling $52 million in 2014, which is included within charges related to arbitration award in the consolidated statements of income. This amount is in addition to the $25 million previously accrued in the fourth quarter of fiscal 2011. The total amount accrued of $758 million represents the amount of the final arbitration award, plus interest accrued on the initial arbitration award at the statutory rate of 10% from January 24, 2012 through June 27, 2014.

Other Matters

On December 22, 2011 the German Central Organization for Private Copying Rights (Zentralstelle für private Überspielungsrechte), ("ZPÜ”), an organization consisting of several levy collecting societies, submitted a pleading to the Copyright Arbitration Board (“CAB”) in Munich claiming retroactive copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce in Germany by WD from January 2008 through December 2010. The CAB was required to issue a settlement proposal within one year of the initiation of the action, failed to do so and requested the parties to consent to continue the deadline. WD declined to provide consent and, on February 1, 2013, WD filed a declaratory relief against ZPÜ in the Higher Regional Court of Munich (the “Higher Court”), seeking an order from the court to determine the copyright levy issue. On May 21, 2013, ZPÜ filed a counter-claim against WD with the Higher Court, seeking copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce from January 2008 through December 2010 based on tariffs published by ZPÜ on November 3, 2011. On May 22, 2014, oral argument on the pleadings occurred. A decision from the Higher Court is expected by October 30, 2014, which either party may appeal. WD intends to defend itself vigorously in this matter.

In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties and is therefore not predictable with assurance, management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability or financial impact to the Company from these other matters could differ materially from those projected.

Note 7. Western Digital Corporation 401(k) Plan

The Company has adopted the Western Digital Corporation 401(k) Plan (the “Plan”). The Plan covers substantially all domestic employees, subject to certain eligibility requirements. The Company makes a basic matching contribution on behalf of each participating eligible employee equal to fifty percent (50%) of the eligible participant’s pre-tax contributions for the contribution cycle not to exceed 5% of the eligible participant’s compensation; provided, however, that each eligible participant shall receive a minimum annual basic matching contribution equal to fifty percent (50%) of the first $4,000 of pre-tax contributions for any calendar year. The Plan was amended effective January 1, 2013, to provide for a year-end true-up matching contribution such that participants who save at least 5% of their eligible compensation for the year receive a minimum annual matching contribution equal to 2.5% of eligible compensation (up to Internal Revenue Service (“IRS”) limitations). Company contributions vest over a 5-year period of employment. For 2014, 2013, and 2012, the Company made Plan contributions of $21 million, $19 million and $12 million, respectively.

Note 8. Shareholders’ Equity

Stock Incentive Plans

In addition to awards assumed in connection with acquisitions, the Company maintains two stock-based incentive plans (collectively, including the assumed awards, referred to as the “Stock Plans”): the amended and restated 2004 Performance Incentive Plan and the Employee Stock Option Plan. No new awards may be granted under the Employee Stock Option Plan. As of June 27, 2014, options to purchase 77,033 shares of the Company’s common stock remained outstanding and exercisable under the Employee Stock Option Plan. Other than for such options, no restricted stock or other awards were outstanding under the Employee Stock Option Plan as of June 27, 2014. Options granted under the Employee Stock Option Plan expire ten years from the date of grant.

The types of awards that may be granted under the 2004 Performance Incentive Plan include stock options, SARs, RSUs, stock bonuses and other forms of awards granted or denominated in the Company’s common stock or units of the Company’s common stock, as well as cash bonus awards. Persons eligible to receive awards under the 2004 Performance Incentive Plan include officers and employees of the Company or any of its subsidiaries, directors of the Company and certain consultants and advisors to the Company or any of its subsidiaries. The vesting of awards under the 2004 Performance Incentive Plan is determined at the date of grant. Each award expires on a date determined at the date of grant; however, the maximum term of options and SARs under the 2004 Performance Incentive Plan is ten years after the grant date of the award. RSUs granted under the 2004 Performance Incentive Plan typically vest over periods ranging from one to four years from the date of grant. To the extent available, the Company issues shares out of treasury stock upon the vesting of awards or the exercise of employee stock options and ESPP.

As of June 27, 2014, the maximum number of shares of the Company’s common stock that was authorized for award grants under the 2004 Performance Incentive Plan was 48.8 million shares. Any shares subject to awards under the Employee Stock Option Plan that are canceled, forfeited or otherwise terminate without having vested or been exercised, as applicable, will become available for other award grants under the 2004 Performance Incentive Plan. Shares issued in respect of stock options and SARs granted under the 2004 Performance Incentive Plan count against the plan’s share limit on a one-for-one basis, whereas shares issued in respect of any other type of award granted through November 7, 2012 under the plan count against the plan’s share limit as 1.35 shares for every one share actually issued in connection with such award. Shares issued in respect of awards granted on or after November 8, 2012 count against the plan’s share limit as 1.72 shares for every one share actually issued in connection with such award. The 2004 Performance Incentive Plan was extended in 2013 and will terminate on August 6, 2022 unless terminated earlier by the Company’s Board of Directors.

Employee Stock Purchase Plan

The Company maintains an ESPP. Under the ESPP, eligible employees may authorize payroll deductions of up to 10% of their eligible compensation during prescribed offering periods to purchase shares of the Company’s common stock at 95% of the fair market value of common stock on either the first day of that offering period or on the applicable exercise date, whichever is less. A participant may participate in only one offering period at a time, and a new offering period generally begins each June 1st and December 1st. Each offering period is generally 24 months and consists of four exercise dates (each, generally six months following the start of the offering period or the preceding exercise date, as the case may be). If the fair market value of the Company’s common stock is less on a given exercise date than on the date of grant, employee participation in that offering period ends and participants are automatically re-enrolled in the next new offering period.

Stock-based Compensation Expense

The Company recognized in expense $85 million, $88 million and $57 million for stock-based compensation related to the vesting of options issued by the Company under the Stock Plans and the ESPP in 2014, 2013 and 2012, respectively. The tax benefit realized as a result of the aforementioned stock-based compensation expense was $22 million, $25 million and $12 million in 2014, 2013 and 2012, respectively. As of June 27, 2014, total compensation cost related to unvested stock options granted under the Stock Plans and ESPP rights issued to employees but not yet recognized was $128 million and will be amortized on a straight-line basis over a weighted average service period of approximately 2.2 years.

For purposes of this footnote, references to RSUs include performance stock unit awards (“PSUs”). The effect of the PSU activity was immaterial to the consolidated financial statements in 2014, 2013 and 2012. The Company granted approximately 1.4 million RSUs during 2014, which are generally payable in an equal number of shares of the Company’s common stock at the time of vesting of the units. The aggregate market value of the shares underlying the RSUs granted in 2014 was $95 million at the date of grant. The compensation expense for granted and assumed RSUs is being recognized as

71

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

expense over the corresponding vesting or measurement periods of the awards. For purposes of recognizing awards granted, the Company has assumed a weighted average forfeiture rate of 3.3% based on a historical analysis indicating forfeitures for these types of awards. The Company recognized in expense $71 million, $52 million and $35 million related to RSUs granted under the Stock Plans that vested during 2014, 2013 and 2012, respectively. The tax benefit realized as a result of the aforementioned expense was $18 million, $14 million and $10 million in 2014, 2013 and 2012, respectively. As of June 27, 2014, the aggregate unamortized fair value of all unvested RSUs granted under the Stock Plans was $91 million, which will be recognized on a straight-line basis over a weighted average vesting period of approximately 1.4 years. In 2013, stock-based compensation expense included $5 million of accelerated expense associated with the employee termination benefits as discussed in Note 17.

The Company recognized in expense $36 million and $46 million related to adjustments to market value as well as the vesting of SARs in 2014 and 2013, respectively, and a benefit of $7 million related to SARs in 2012. The tax benefit realized as a result of the aforementioned SARs expense was $7 million and $4 million in 2014 and 2013, respectively. There was no tax effect in 2012. The SARs will be settled in cash upon exercise. As a result, the Company had a total liability of $61 million related to SARs included in accrued liabilities as of June 27, 2014 in the consolidated balance sheet. As of June 27, 2014, total compensation cost related to unvested SARs issued to employees but not yet recognized was $1 million and will be recognized on a straight-line basis over a weighted average service period of approximately 0.5 years.

Stock Option Activity

The following table summarizes stock option activity under the Stock Plans over the last three fiscal years (in millions, except per share amounts and remaining contractual lives):

	Number of Shares		Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value

Vested and expected to vest after June 27, 2014	9.9		$	36.82	4.5	$	565

If an option has an exercise price that is less than the quoted price of the Company’s common stock at the particular time, the aggregate intrinsic value of that option at that time is calculated based on the difference between the exercise price of the underlying options and the quoted price of the Company’s common stock at that time. As of June 27, 2014, the Company had options outstanding to purchase an aggregate of 10.0 million shares with an exercise price below the quoted price of the Company’s stock on that date resulting in an aggregate intrinsic value of $572 million at that date. During 2014, 2013 and 2012, the aggregate intrinsic value of options exercised under the Stock Plans was $247 million, $211 million and $53 million, respectively, determined as of the date of exercise.

The following table summarizes information about options outstanding and exercisable under the Stock Plans as of June 27, 2014 (in millions, except exercise price):

RSUs outstanding at June 27, 2014	3.7		$	49.77
Expected to vest after June 27, 2014	3.5		$	49.48

The fair value of each RSU is the market price of the Company’s stock on the date of grant. RSUs are generally payable in an equal number of shares of the Company’s common stock at the time of the vesting of the units. The aggregate value of RSUs that became fully-vested during 2014, 2013 and 2012 was $89 million, $71 million and $41 million, respectively, determined as of the vest date. The grant-date fair value of the shares underlying the RSU awards at the date of grant or assumption was $95 million, $74 million and $71 million in 2014, 2013 and 2012, respectively. These amounts are being recognized to expense over the corresponding vesting periods. For purposes of valuing these awards, the Company has assumed a forfeiture rate of 3.3%, 2.0% and 2.4% during 2014, 2013 and 2012, respectively, based on a historical analysis indicating forfeitures for these types of awards.

SARs Activity

The share-based compensation liability for SARs is recognized for the portion of fair value for which service has been rendered at the reporting date. The share-based liability is remeasured at each reporting date, using a binomial option-pricing model, through the requisite service period. As of June 27, 2014, 0.7 million SARs were outstanding with a weighted

73

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

average exercise price of $7.96. There were no SARs granted and all other SARs activity was immaterial to the consolidated financial statements for the year ended June 27, 2014.

Fair Value Disclosure — Binomial Model

The fair value of stock options granted is estimated using a binomial option-pricing model. The binomial model requires the input of highly subjective assumptions. The Company uses historical data to estimate exercise, employee termination, and expected stock price volatility within the binomial model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of stock options granted during the three years ended June 27, 2014 was estimated using the following weighted average assumptions:

	2014	2013	2012
Suboptimal exercise factor	2.07	1.90	1.81
Range of risk-free interest rates	0.10% to 2.44%	0.14% to 1.96%	0.12% to 1.61%
Range of expected stock price volatility	0.27 to 0.50	0.36 to 0.53	0.41 to 0.55
Weighted average expected volatility	0.43	0.49	0.49
Post-vesting termination rate	3.10%	2.16%	2.61%
Dividend yield	1.58%	2.53%	—
Fair value	$24.14	$15.75	$12.91

The weighted average expected term of the Company’s stock options granted during 2014, 2013 and 2012 was 5.0 years, 4.0 years and 4.9 years, respectively.

Fair Value Disclosure — Black-Scholes-Merton Model

The fair value of ESPP purchase rights issued is estimated at the date of grant of the purchase rights using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model requires the input of highly subjective assumptions such as the expected stock price volatility and the expected period until options are exercised. Purchase rights under the ESPP are granted on either June 1st or December 1st of each year.

The fair values of all ESPP purchase rights granted on or prior to June 27, 2014 have been estimated at the date of grant using a Black-Scholes-Merton option-pricing model with the following weighted average assumptions:

	ESPP
	2014	2013	2012
Option life (in years)	1.24	1.24	1.24
Risk-free interest rate	0.26%	0.23%	0.22%
Stock price volatility	0.31	0.42	0.46
Dividend yield	1.64%	1.61%	—
Fair value	$14.62	$10.36	$7.29

Stock Repurchase Program

Since May 18, 2012, the Company's Board of Directors has authorized $3.0 billion for the repurchase of its common stock until September 13, 2017. The Company repurchased 10.3 million shares for a total cost of $816 million during 2014. The remaining amount available to be purchased under the Company’s stock repurchase program as of June 27, 2014 was $1.2 billion. The Company may continue to repurchase its stock as it deems appropriate and market conditions allow. Repurchases under the stock repurchase program may be made in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. The Company expects stock repurchases to be funded principally by operating cash flows and borrowings under the Credit Agreement.

Dividends to Shareholders

On September 13, 2012, the Company announced that its Board of Directors had authorized the adoption of a quarterly cash dividend policy. Under the cash dividend policy, holders of the Company’s common stock receive dividends when and as declared by the Company’s Board of Directors. In 2014, the Company declared aggregate cash dividends of $1.25 per share of the Company’s common stock, totaling $295 million, of which $201 million was paid during 2014. On August 5, 2014, the Company declared a cash dividend of $0.40 per share of its common stock to shareholders of record as of October 3, 2014, which will be paid on October 15, 2014. The Company may modify, suspend or cancel its cash dividend policy in any manner and at any time.

Note 9. Income Taxes

Income Tax Provision

The components of the provision for income taxes were as follows for the three years ended June 27, 2014 (in millions):

	2014			2013			2012
Current:

Domestic-federal	(14		)	(46		)	25
Domestic-state	4			88			(9		)
Income tax provision	$	135		$	242		$	145

The Company’s income tax provision for 2013 reflects a tax benefit of $37 million as a result of the retroactive extension of the U.S. Federal research and experimentation tax credit (“R&D credit”) that was signed into law on January 2, 2013 as part of the American Taxpayer Relief Act of 2012. The R&D credit, which had previously expired on December 31, 2011, was extended through December 31, 2013. In addition, the Company recorded an $88 million charge to reduce its previously recognized California deferred tax assets in 2013 as a result of the enactment of California Proposition 39.

Remaining net undistributed earnings from foreign subsidiaries at June 27, 2014 on which no U.S. tax has been provided amounted to $8.2 billion. The net undistributed earnings are intended to finance local operating requirements and capital investments. Accordingly, an additional U.S. tax provision has not been made on these earnings. The tax liability for

these earnings would be $2.7 billion if the Company repatriated the $8.2 billion in undistributed earnings from the foreign subsidiaries.

Deferred Taxes

Temporary differences and carryforwards, which give rise to a significant portion of deferred tax assets and liabilities as of June 27, 2014 and June 28, 2013 were as follows (in millions):

	2014			2013
Deferred tax assets:
Sales related reserves and accrued expenses not currently deductible	$	38		$	45
Accrued compensation and benefits not currently deductible	190			182
Domestic net operating loss carryforward	130			103

Valuation allowances (included in non-current portion of deferred tax assets)	(128		)	(133		)
Deferred tax assets, net	$	345		$	282

The net deferred tax asset valuation allowance was $128 million as of June 27, 2014. The valuation allowance is based on the Company’s assessment that it is more likely than not that certain deferred tax assets will not be realized in the foreseeable future.

In addition to the deferred tax assets presented above, the Company had additional NOL benefits related to stock-based compensation deductions of $11 million and $13 million at June 27, 2014 and June 28, 2013, respectively. During the current year, the Company generated an additional $66 million of benefits related to stock-based compensation deductions, of which $60 million were utilized in the current year and recorded as a credit to shareholder's equity.

Effective Tax Rate

Reconciliation of the U.S. Federal statutory rate to the Company’s effective tax rate is as follows for the three years ended June 27, 2014:

	2014		2013		2012
U.S. Federal statutory rate	35	%	35	%	35	%
Tax rate differential on international income	(28	)	(19	)	(29	)

Effective tax rate	8	%	20	%	8	%

Tax Holidays and Carryforwards

A substantial portion of the Company’s manufacturing operations in Malaysia, the Philippines, Singapore and Thailand operate under various tax holidays and tax incentive programs which will expire in whole or in part at various dates from 2015 through 2025. Certain of the holidays may be extended if specific conditions are met. The net impact of these tax holidays and tax incentives was to increase the Company’s net earnings by $905 million ($3.74 per diluted share), $899 million ($3.65 per diluted share), and $729 million ($2.98 per diluted share) in 2014, 2013 and 2012, respectively.

As of June 27, 2014, the Company had federal and state NOL carryforwards of $440 million and $480 million, respectively. In addition, as of June 27, 2014, the Company had various federal and state tax credit carryforwards of $331 million combined. The NOL carryforwards available to offset future federal and state taxable income expire at various dates from 2020 to 2032 and 2017 to 2032, respectively. Approximately $50 million of the credit carryforwards available to offset future taxable income expire at various dates from 2016 to 2033. The remaining amount is available indefinitely. NOLs and credits relating to Komag, Incorporated (“Komag”), which was acquired by the Company on September 5, 2007, HGST, sTec and Virident are subject to limitations under Sections 382 and 383 of the Internal Revenue Code. The Company does not expect these limitations to result in a reduction in the total amount of Komag, sTec or Virident's NOLs and credits ultimately realized. The Company expects the total amount of HGST’s NOLs and credits ultimately realized will be reduced by $39 million and $25 million, respectively. Because the Company expects the amount of HGST’s NOLs and credits ultimately realized will be reduced, the Company has adjusted goodwill accordingly.

Uncertain Tax Positions

The Company recognizes liabilities for uncertain tax positions based on a two-step process. First, the tax position is evaluated for recognition by determining if it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to be recognized in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. With the exception of certain unrecognized tax benefits that are directly associated with the tax position taken, unrecognized tax benefits are presented gross in the Company’s balance sheet. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. As of June 27, 2014, such interest and penalties were not material. As of June 27, 2014, the Company had $300 million of unrecognized tax benefits.

WESTERN DIGITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits for the years ended June 27, 2014, June 28, 2013 and June 29, 2012 (in millions):

	2014			2013			2012
Unrecognized tax benefit at beginning of period	$	240		$	280		$	245

Lapse of statute of limitations	—			(7		)	—
Acquisitions	12			—			39
Unrecognized tax benefit at end of period	$	300		$	240		$	280

The Company’s unrecognized tax benefits are primarily included within long-term liabilities in the Company’s consolidated balance sheets. The entire balance of unrecognized tax benefits at June 27, 2014, June 28, 2013 and June 29, 2012, if recognized, would affect the effective tax rate.

The Company files U.S. Federal, U.S. state, and foreign tax returns. For both federal and state tax returns, with few exceptions, the Company is subject to examination for fiscal years 2008 through 2013. In foreign jurisdictions, with few exceptions, the Company is subject to examination for all years subsequent to fiscal 2007. The Company is no longer subject to examination by the IRS for periods prior to 2008, although carry forwards generated prior to those periods may still be adjusted upon examination by the IRS or state taxing authority if they either have been or will be used in a subsequent period.

The IRS previously completed its field examination of the Company’s federal income tax returns for fiscal years 2006 and 2007 and issued Revenue Agent Reports that proposed adjustments to income before income taxes of approximately $970 million primarily related to transfer pricing and intercompany payable balances. The Company disagreed with the proposed adjustments and filed a protest with the IRS Appeals Office. In June 2013, the Company reached an agreement with the IRS to resolve the transfer pricing issue. This agreement resulted in a decrease in the amount of net operating loss and tax credits realized, but did not have an impact to the Company’s consolidated statements of income. The proposed adjustment relating to intercompany payable balances for fiscal years 2006 and 2007 will be addressed in conjunction with the IRS’s examination of the Company’s fiscal years 2008 and 2009, which commenced in January 2012. In addition, in January 2012, the IRS commenced an examination of the 2007 fiscal period ended September 5, 2007 of Komag. In February 2013, the IRS commenced an examination of calendar years 2010 and 2011 of HGST, which was acquired by the Company on March 8, 2012.

The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of June 27, 2014, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s tax returns.

Note 10. Fair Value Measurements

Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3. Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.

Assumptions

Weighted-Average Assumptions

The weighted-average actuarial assumptions used to determine benefit obligations for the Japanese defined benefit pension plans were as follows for 2014, 2013 and 2012:

83

WESTERN DIGITAL CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

	2014		2013		2012
Discount rate	1.6	%	1.6	%	1.8	%
Rate of compensation increase	1.0	%	0.9	%	1.4	%

The weighted-average actuarial assumptions used to determine benefit costs for the Japanese defined benefit pension plans were as follows for 2014, 2013 and 2012:

	2014		2013		2012
Discount rate	1.6	%	1.8	%	1.9	%
Expected long-term rate of return on plan assets	3.5	%	3.5	%	3.5	%
Rate of compensation increase	0.9	%	1.2	%	1.4	%

The Company develops a discount rate by calculating when the estimated benefit payments will be due. Management in Japan then matches the benefit payments to AA or higher bond ratings that match the timing of the expected benefit payments to determine the appropriate discount rate.

The Company develops the expected long-term rate of return on plan assets by analyzing rates of return in Japan as well as the investment portfolio applicable to the plan. Management’s estimates of future rates of return on assets is based in large part on the projected rate of return from the respective investment managers using a long-term view of historical returns, as well as actuarial recommendations using the most current generational and mortality tables and rates.

The Company develops the rate of compensation increase assumptions using local compensation practices and historical rates of increases.

Plan Assets

Investment Policies and Strategies

The investment policy in Japan is to generate a stable return on investments over a long-term horizon in order to have adequate pension funds to meet the Company’s future obligations. In order to achieve this investment goal, a diversified portfolio with target asset allocation and expected rate of return is established by considering factors such as composition of participants, level of funded status, capacity to absorb risks, and the current economic environment. The target asset allocation is 35% in equity securities, 62% in debt securities and the remaining 3% in other assets. Risk management is accomplished through diversification, periodic review of plan asset performance, and appropriate realignment of asset allocation. Assumptions regarding the expected long-term rate of return on plan assets are periodically reviewed and are based on the historical trend of returns, the risk and correlation of each asset, and the latest economic environment.

The expected long-term rate of return is estimated based on many factors, including expected forecast for inflation, risk premiums for each asset class, expected asset allocation, current and future financial market conditions, and diversification and rebalancing strategies. Historical return patterns and correlations, consensus return forecasts, and other relevant financial factors are analyzed periodically by the investment advisor so as to ensure that the expected long-term rate of return is reasonable and appropriate.

⁽³⁾  Fixed income mutual funds invest primarily in fixed income securities.

Assets held in defined benefit plans in the Philippines, Taiwan and Thailand were less than $1 million and are not presented in the above table. There were no significant movements of assets between any level categories in 2014, 2013 or 2012.

Fair Value Valuation Techniques

Equity securities are valued at the closing price reported on the stock exchange on which the individual securities are traded. Equity commingled/mutual funds are typically valued using the net asset value (“NAV”) provided by the investment manager or administrator of the fund. The NAV is based on the value of the underlying assets owned by the fund, minus liabilities and divided by the number of shares or units outstanding. These assets are classified as either Level 1 or Level 2, depending on availability of quoted market prices for identical or similar assets.

If available, fixed income securities are valued using the close price reported on the major market on which the individual securities are traded and are classified as Level 1. The fair value of other fixed income securities is typically estimated using pricing models and quoted prices of securities with similar characteristics, and is generally classified as Level 2.

Cash includes money market accounts that are valued at their cost plus interest on a daily basis, which approximates fair value. Short-term investments represent securities with original maturities of one year or less. These assets are classified as either Level 1 or Level 2.

Cash Flows

Contributions

The Company’s expected employer contributions for 2015 are $14 million for its Japanese defined benefit pension plans.

Estimated Future Benefits Payments

Annual benefit payments from the Japanese defined benefit pension plans are estimated to range from $7 million to $11 million annually over the next five years.

Note 15. Acquisitions

Acquisition of Virident

On October 17, 2013, the Company acquired Virident, a provider of server-side flash storage solutions for virtualization, database, cloud computing and webscale applications. As a result of the acquisition, Virident has been fully integrated into the Company's HGST subsidiary and become a wholly owned indirect subsidiary of the Company. The purchase price of the acquisition was approximately $613 million, consisting of $598 million which was funded with available cash, and $15 million related to the fair value of stock options assumed. The acquisition furthered HGST's strategy to address the rapidly changing

needs of enterprise customers by delivering intelligent storage solutions that maximize application performance by leveraging the tightly coupled server, storage and network resources of today’s converged datacenter infrastructures.

The Company identified and recorded the assets acquired and liabilities assumed at their estimated fair values at the date of acquisition, and allocated the remaining value of $506 million to goodwill. The values assigned to the acquired assets and liabilities were finalized as of the date of this Annual Report on Form 10-K. The individual tangible and intangible assets acquired as well as the liabilities assumed in the acquisition were immaterial to the Company's consolidated financial statements. In addition, pro forma financial information has not been presented as the acquisition did not have a material impact on the Company’s consolidated financial statements in 2014.

The final purchase price allocation for Virident was as follows (in millions):

	October 17, 2013
Tangible assets acquired and liabilities assumed	$	58
Intangible assets	49
Goodwill	506
Total	$	613

Since the date of acquisition, the Company recorded an increase of $4 million to goodwill to reflect an adjustment to the value of deferred tax assets and an adjustment to the value of investments acquired in the acquisition of Virident. The $506 million of goodwill recognized is primarily attributable to the benefits the Company expects to derive from an ability to create server-side flash storage solutions leveraging the core technology acquired and is not expected to be deductible for tax purposes. The impact to revenue and net income attributable to Virident was immaterial to the Company’s consolidated financial statements in 2014.

Acquisition of sTec

On September 12, 2013, the Company completed its acquisition of sTec, a provider of enterprise solid-state drives. As a result of the acquisition, sTec has been fully integrated into the Company's HGST subsidiary and become a wholly owned indirect subsidiary of the Company. The purchase price of the acquisition was approximately $336 million, consisting of $325 million which was funded with available cash, and $11 million related to the fair value of stock options and RSUs assumed. The acquisition augmented HGST's existing solid-state storage capabilities.

The Company identified and recorded the assets acquired and liabilities assumed at their estimated fair values at the date of acquisition, and allocated the remaining value of $89 million to goodwill. The values assigned to the acquired assets and liabilities are based on preliminary estimates of fair value available as of the date of this Annual Report on Form 10-K, and may be adjusted as further information becomes available during the measurement period of up to 12 months from the date of the acquisition. The primary areas of the preliminary purchase price allocation that are not yet finalized due to information that may become available subsequently include contingencies and income taxes, and any changes in these fair values could potentially result in material adjustments to goodwill. The individual tangible and intangible assets acquired as well as the liabilities assumed in the acquisition were immaterial to the Company's consolidated financial statements. In addition, pro forma financial information has not been presented as the acquisition did not have a material impact on the Company’s consolidated financial statements for 2014.

The preliminary purchase price allocation for sTec was as follows (in millions):

	September 12, 2013
Tangible assets acquired and liabilities assumed	$	189
Intangible assets	58
Goodwill	89
Total	$	336

Since the date of acquisition, the Company recorded a $1 million increase to goodwill to reflect an adjustment to the value of deferred tax assets acquired in the acquisition of sTec. The $89 million of goodwill recognized is primarily attributable to the benefits the Company expects to derive from augmenting HGST's existing solid-state storage capabilities and accelerating its ability to expand its participation in the growing area of enterprise solid-state drives and is not expected to be deductible for tax

Acquisition of VeloBit

On July 9, 2013, the Company acquired VeloBit, a privately held provider of high-performance storage I/O optimization software. As a result of the acquisition, VeloBit was fully integrated into the Company's HGST subsidiary and became a wholly owned indirect subsidiary of the Company. The acquisition built on HGST's strategy to enhance the overall value of datacenter storage by integrating HGST SSDs with software. The acquisition was not material to the Company's consolidated financial statements.

Note 16. Thailand Flooding

In October 2011, severe flooding in Thailand inundated all of the Company’s Thailand manufacturing facilities and submerged certain equipment located there. These facilities included the Company’s magnetic head slider fabrication facilities, as well as its hard drive, head gimbal assembly and head stack assembly facilities. As a result, the Company recorded $235 million of flood-related charges in fiscal 2012, offset by $21 million of insurance recoveries and other cost reimbursements. These charges are separately stated as a line item, “Charges related to flooding, net,” within operating expenses on the consolidated statements of income.

The Company maintains insurance coverage that provides property and business interruption coverage in the event of losses arising from flooding. The Company has submitted claims to its insurers and is awaiting a determination of how much of its total losses will be covered by insurance.

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

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As required by SEC Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures (as such term is defined in Rule 13a-15(e) under the Exchange Act) as of the end of the period covered by this Annual Report on Form 10-K.

Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this Annual Report on Form 10-K, our disclosure controls and procedures were effective.

Management’s Report on Internal Control over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (ii) provide reasonable assurance that the transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and our directors; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Our management evaluated the effectiveness of our internal control over financial reporting using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (1992). Based on this evaluation, our management concluded that our internal control over financial reporting was effective as of the end of the period covered by this Annual Report on Form 10-K. KPMG LLP, our independent registered public accounting firm, which audited the consolidated financial statements included in this Annual Report on Form 10-K, has issued an audit report on our internal control over financial reporting. See page 51 herein.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during the fourth fiscal quarter ended June 27, 2014, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations of Effectiveness of Controls

Our management, including our Chief Executive Officer and our Chief Financial Officer, does not expect our internal controls over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a system of internal control over financial reporting, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Summary of Compensation Arrangements

for

Named Executive Officers and Directors

NAMED EXECUTIVE OFFICERS

Base Salaries. The current annual base salaries for the current executive officers of Western Digital Corporation (the “Company”) who were named in the Summary Compensation Table in the Company’s Proxy Statement that was filed with the Securities and Exchange Commission in connection with the Company’s 2013 Annual Meeting of Stockholders (the “Named Executive Officers”) are as follows:

Named Executive Officer	Title	Current Base Salary
Stephen D. Milligan	President and Chief Executive Officer	$	1,050,000
Timothy M. Leyden	Chief Financial Officer	$	700,000
Michael D. Cordano	President, HGST Subsidiary	$	700,000
James J. Murphy	President, WD Subsidiary	$	550,000

Semi-Annual Bonuses. Under the Company’s Incentive Compensation Plan (the “ICP”), the Named Executive Officers are also eligible to receive semi-annual cash bonus awards that are determined based on the Company’s achievement of performance goals pre-established by the Compensation Committee (the “Committee”) of the Company’s Board of Directors as well as other discretionary factors. The ICP, including the performance goals established by the Committee for the second half of fiscal 2014, are further described in the Company’s current report on form 8-K filed with the Securities and Exchange Commission on February 10, 2014, which is incorporated herein by reference.

Additional Compensation. The Named Executive Officers are also eligible to receive equity-based incentives and discretionary bonuses as determined from time to time by the Committee, are entitled to participate in various Company plans, and are subject to other written agreements, in each case as set forth in exhibits to the Company’s filings with the Securities and Exchange Commission. In addition, the Named Executive Officers may be eligible to receive perquisites and other personal benefits as disclosed in the Company’s Proxy Statement filed with the Securities and Exchange Commission in connection with the Company’s 2013 Annual Meeting of Stockholders.

DIRECTORS

Annual Retainer and Committee Retainer Fees. The following table sets forth the current annual retainer and committee membership fees payable to each of the Company’s non-employee directors other than the Hitachi Designated Directors:

Type of Fee	Current Annual Retainer Fees
Annual Retainer	$	75,000
Lead Independent Director Retainer	$	20,000
Non-Executive Chairman of Board Retainer	$	100,000
Additional Committee Retainers
•     Audit Committee	$	15,000
•     Compensation Committee	$	12,500
•     Governance Committee	$	7,500
Additional Committee Chairman Retainers
•     Audit Committee	$	25,000
•     Compensation Committee	$	22,500
•     Governance Committee	$	12,500

The retainer fee to the Company’s lead independent director referred to above is paid only if the Chairman of the Board is an employee of the Company. Effective commencing with the Company’s 2010 Annual Meeting of Stockholders, the annual retainer fees are paid immediately following the Annual Meeting of Stockholders.

Non-employee directors do not receive a separate fee for each Board of Directors or committee meeting they attend. However, the Company reimburses all non-employee directors for reasonable out-of-pocket expenses incurred to attend each Board of Directors or committee meeting. Mr. Milligan, who is an employee of the Company, does not receive any compensation for his service on the Board or any Board committee.

Additional Director Compensation. The Company’s non-employee directors are also entitled to participate in the following other Company plans as set forth in exhibits to the Company’s filings with the Securities and Exchange Commission: Non-Employee Director Restricted Stock Unit Grant Program, as adopted under the Company’s Amended and Restated 2004 Performance Incentive Plan; and Deferred Compensation Plan.

Hitachi Designated Director Compensation Program. On August 14, 2013, we entered into an agreement with Hitachi, Ltd. (“Hitachi”) by which we agreed to make certain payments to Hitachi in lieu of our prior undertaking in the Investor Rights Agreement to compensate the Hitachi Designated Directors on the same basis that we compensate other non-employee directors. For each of the Hitachi Designated Directors, Hitachi received an initial payment of $260,959, which is reported in the “Director Compensation Table for Fiscal 2013” in the Company’s Proxy Statement that was filed with the Securities and Exchange Commission in connection with the Company’s 2013 Annual Meeting of Stockholders. For each year of service commencing with the 2013 Annual Meeting of Stockholders, Hitachi is entitled to a cash payment with respect to each continuing Hitachi Designated Director equal to the base annual retainer otherwise payable to one of our other non-employee directors pursuant to our non-employee director compensation policy then in effect (which is summarized above). Hitachi also will be entitled to an additional cash payment(s) determined by reference to the grants of RSUs the Hitachi Designated Directors would have been granted had such Hitachi Designated Directors participated in our Non-Employee Director Restricted Stock Unit Grant Program under our 2004 Performance Incentive Plan. Such cash payment(s) will be payable to Hitachi within ten (10) days after the date on which such hypothetical RSUs would have vested had such units actually been granted to the Hitachi Designated Directors under the terms of the program, and will be calculated based on the number of units that would have vested multiplied by the closing price of a share of our common stock on the vesting date. Hitachi will not be entitled to any cash payment with respect to any hypothetical RSUs for which the applicable vesting conditions would not have been satisfied by the applicable Hitachi Designated Director. The Hitachi Designated Directors are not entitled to any compensation from us for their service on our Board of Directors but are entitled to the same travel and expense reimbursement as our other non-employee directors.

Accounting Policies [Abstract]

Organization and Summary of Significant Accounting Policies

Note 1. Organization and Summary of Significant Accounting Policies

Western Digital Corporation (the “Company” or “Western Digital”) is a leading developer, manufacturer and provider of data storage solutions that enable consumers, businesses, governments and other organizations to create, manage, experience and preserve digital content. The Company's product portfolio includes hard disk drives (“HDDs”) and solid-state drives ("SSDs"). HDDs are the Company's principal products and are today’s primary storage medium for digital content, with the use of solid-state storage products growing rapidly. The Company's products are marketed under the HGST, WD and G-Technology brand names.  The Company currently operate our global business through two independent subsidiaries due to regulatory requirements—HGST and WD.

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 2014, 2013 and 2012 fiscal years which ended on June 27, 2014, June 28, 2013 and June 29, 2012, respectively, consisted of 52 weeks each.

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In fiscal 2014 and fiscal 2013, the accounts for all foreign subsidiaries have been remeasured using the U.S. dollar as the functional currency. In fiscal 2012, the accounts for all foreign subsidiaries, except for one Japanese subsidiary in which Yen was the functional currency, have been remeasured using the U.S. dollar as the functional currency. Gains or losses resulting from remeasurement or translation of these accounts from local currencies into U.S. dollars were immaterial to the consolidated financial statements.

The Company acquired Virident Systems, Inc. ("Virident") on October 17, 2013, sTec, Inc. (“sTec”) on September 12, 2013, and VeloBit, Inc. ("VeloBit") on July 9, 2013. In addition, on March 8, 2012, the Company completed its acquisition of all of the issued and paid-up share capital of Viviti Technologies Ltd., known until shortly before acquisition as Hitachi Global Storage Technologies Holdings Pte. Ltd. (“HGST”), from Hitachi, Ltd. (“Hitachi”). These acquisitions are further described in Note 15 below. In connection with the acquisitions, Virident, sTec, VeloBit and HGST became indirect wholly-owned subsidiaries of the Company. The results of operations of Virident, sTec, VeloBit and HGST since the respective dates of acquisition are included in the consolidated financial statements.

Cash and Cash Equivalents

The Company’s cash equivalents represent highly liquid investments in money market funds, which are invested in U.S. Treasury securities and U.S. Government agency securities as well as direct investments in bank acceptances with original maturities when purchased of three months or less. Cash equivalents are carried at cost, which approximates fair value.

Investments

The Company's investments in U.S. Treasury securities, U.S. Government agency securities, commercial paper and certificates of deposit with original maturities at purchase of more than three months. These investments are classified as available-for-sale securities and included within short-term investments and other non-current assets in the consolidated balance sheets. Available-for-sale securities are stated at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss), which is a component of shareholders' equity. The Company evaluates the available-for sale securities in an unrealized loss position for other-than-temporary impairment. The amortized cost of available-for-sale securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest and other income and other in the consolidated statements of income. In addition, realized gains and losses are included in total other expense, net in the consolidated statements of income.

In addition, the Company enters into certain strategic investments for the promotion of business and strategic objectives. These strategic investments are recorded at cost within other non-current assets in the consolidated balance sheets and are periodically analyzed to determine whether or not there are indicators of impairment. Lastly, the Company’s investments included auction-rate securities which were all sold during 2014. The Company's auction rate securities were classified as available-for-sale securities and carried at fair value within other non-current assets in the consolidated balance sheets.

Fair Value of Financial Instruments

The carrying amounts of cash equivalents, accounts receivable, investments, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities or, in the case of investments, these are recorded using appropriate market information. The carrying amount of debt approximates fair value because of its variable interest rate.

Concentration of Credit Risk

The Company sells its products to computer manufacturers, resellers and retailers throughout the world. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. The Company maintains allowances for potential credit losses, and such losses have historically been within management’s expectations. At any given point in time, the total amount outstanding from any one of a number of its customers may be individually significant to the Company’s financial results. At June 27, 2014 and June 28, 2013, the Company had two customers that accounted for 29% of the Company's net accounts receivable. At June 27, 2014 and June 28, 2013, the Company had reserves for potential credit losses of $11 million and $9 million, respectively, and net accounts receivable of $2.0 billion and $1.8 billion at each date, 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.

Inventories

The Company values inventories at the lower of cost (first-in, first out and weighted average methods) or net realizable value. The first-in, first-out (“FIFO”) method is used to value the cost of the majority of the Company’s inventories, while the weighted-average method is used to value precious metal inventories. Weighted-average cost is calculated based upon the cost of precious metals at the time they are received by the Company. The Company has determined that it is not practicable to assign specific costs to individual units of precious metals and, as such, precious metals are relieved from inventory based on the weighted-average cost of the inventory at the time the inventory is used in production. The weighted average method of valuing precious metals does not materially differ from a FIFO method. As of June 27, 2014 and June 28, 2013, 92% and 91%, 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 the Company’s products, which may require a write down of inventory that could materially affect operating results.

Property, Plant and Equipment

The cost of property, plant and equipment is depreciated over the estimated useful lives of the respective assets. The Company’s buildings are depreciated over periods ranging from fifteen to thirty years. The majority of the Company’s equipment is depreciated over periods of two to seven years. Depreciation is computed on a straight-line basis. Leasehold improvements are amortized over the lesser of the estimated useful lives of the assets or the related lease terms.

Goodwill and Other Long-Lived Assets

The fair value of assets acquired and liabilities assumed in a business acquisition are recognized at the acquisition date, with amounts exceeding the fair values being recognized as goodwill. Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. The Company performs its annual impairment test as of the first day of its fiscal fourth quarter. The Company either uses qualitative factors to determine whether goodwill is more likely than not impaired or performs a two-step approach to quantify impairment. If the Company concludes from the qualitative assessment that goodwill is more likely than not impaired, it is required to follow a two-step approach to quantify the impairment. The Company is required to use judgment when applying the goodwill impairment test, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. In addition, the estimates used to determine the fair value of each reporting unit may change based on results of operations, macroeconomic conditions or other factors. Changes in these estimates could materially affect the Company’s assessment of the fair value and goodwill impairment for each reporting unit. The Company did not record any impairment of goodwill during 2014, 2013, or 2012.

Other intangible assets consist primarily of technology acquired in business combinations and in-process research and development. In-process research and development is not amortized until the point at which it reaches technological feasibility. Instead, it is instead tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that it may be impaired. Acquired intangibles are amortized on a straight-line basis over their respective estimated useful lives. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If impairment is indicated, the impairment is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company recorded impairments to certain long-lived assets in 2014, 2013 and 2012. See Notes 13 and 17.

Revenue and Accounts Receivable

Revenue is recognized when the title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, delivery has occurred, or services have been rendered, the sales price is fixed or determinable and collectability is reasonably assured. The Company establishes provisions against revenue and cost of revenue for estimated sales returns in the same period that the related revenue is recognized based on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.

In accordance with standard industry practice, the Company provides distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions, and the Company provides resellers and OEMs with other sales incentive programs. At the time the Company recognizes revenue to resellers and OEMs, a reduction of revenue is recorded for estimated price protection until the resellers sell such inventory to their customers and the Company also records a reduction of revenue for the other programs in effect. The Company bases these adjustments on several factors including anticipated price decreases during the reseller holding period, reseller’s sell-through and inventory levels, estimated amounts to be reimbursed to qualifying customers, historical pricing information and customer claim processing. If customer demand for the Company's products or market conditions differ from the Company’s expectations, the Company’s operating results could be materially affected. The Company also has programs under which it reimburses qualified distributors and retailers for certain marketing expenditures, which are recorded as a reduction of revenue. Customer sales incentive and marketing programs are recorded as a reduction of revenue.

The Company records an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency, disputes or other collection issues. In addition, the Company routinely analyzes the different receivable aging categories and establishes reserves based on a combination of past due receivables and expected future losses based primarily on its historical levels of bad debt losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if the Company’s overall loss history changes significantly, an adjustment in the Company’s allowance for doubtful accounts would be required, which could materially affect operating results.

Warranty

The Company records an accrual for estimated warranty costs when revenue is recognized. The Company generally warrants its products for a period of one to five years. The warranty provision considers estimated product failure rates and trends, estimated replacement costs, estimated repair costs which include scrap costs, and estimated costs for customer compensatory claims related to product quality issues, if any. A statistical warranty tracking model is used to help prepare estimates and assist the Company in exercising judgment in determining the underlying estimates. The statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Management’s judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base warranty estimates. Management reviews the warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross profit and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from estimates, future results of operations could be materially affected.

Litigation and Other Contingencies

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

Advertising Expense

Advertising costs are expensed as incurred. Selling, general and administrative expenses of the Company included advertising costs of $60 million, $61 million and $30 million in 2014, 2013 and 2012, respectively.

Income Taxes

The Company accounts for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of assets and liabilities and expected benefits of utilizing net operating loss (“NOL”) and tax credit carryforwards. The Company records a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each period, the Company evaluates the need for a valuation allowance for its deferred tax assets and adjusts the valuation allowance so that the Company records net deferred tax assets only to the extent that it has concluded it is more likely than not that these deferred tax assets will be realized.

The Company recognizes liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. The actual liability for unrealized tax benefits 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, and may materially affect the Company’s operating results.

Income per Common Share

The Company computes basic income per common share using net income and the weighted average number of common shares outstanding during the period. Diluted income per common share is computed using net income and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include certain dilutive outstanding employee stock options, rights to purchase shares of common stock under the Company’s Employee Stock Purchase Plan (“ESPP”) and restricted stock unit awards (“RSUs”).

The following table illustrates the computation of basic and diluted income per common share (in millions, except per share data):

	Years Ended
	June 27, 2014		June 28, 2013		June 29, 2012
Net income	$	1,617	$	980	$	1,612

Diluted	$	6.68	$	3.98	$	6.58
Anti-dilutive potential common shares excluded*	2		3		5

_______________

* For purposes of computing diluted income per common share, certain potentially dilutive securities have been excluded from the calculation because their effect would have been anti-dilutive.

Stock-based Compensation

The Company accounts for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options and cash-settled stock appreciation rights (“SARs”) granted are estimated using a binomial option-pricing model, and the fair values of all ESPP purchase rights are estimated using the Black-Scholes-Merton option-pricing model. The Company accounts for SARs as liability awards based upon management’s intention to settle such awards in cash. The SARs liability is recognized for that portion of fair value for the service period rendered at the reporting date. The share-based liability is remeasured at each reporting date through the requisite service period. Both the binomial and the Black-Scholes-Merton option-pricing models require the input of highly subjective assumptions. The Company is required to use judgment in estimating the amount of stock-based awards that are expected to be forfeited. If actual forfeitures differ significantly from the original estimate, stock-based compensation expense and the results of operations could be materially affected.

Other Comprehensive Income (Loss)

Other comprehensive income (loss) refers to revenue, expenses, gains and losses that are recorded as an element of shareholders’ equity but are excluded from net income. The Company’s other comprehensive income (loss) is comprised of unrealized gains and losses on foreign exchange contracts, unrealized gains and losses on the Company's available-for-sale securities, foreign currency translation gains and losses and actuarial gains and losses related to pensions. The income tax impact on components of other comprehensive income is immaterial for all periods presented.

The following table illustrates the changes in the balances of each component of accumulated comprehensive income for 2014, 2013 and 2012:

	Actuarial Pension Gains (Losses)			Foreign Currency Translation Gains (Losses)			Unrealized Gains (Losses) on Foreign Exchange Contracts			Accumulated Other Comprehensive Income (Loss)

Foreign Exchange Contracts

Although the majority of the Company’s transactions are in U.S. dollars, some transactions are based in various foreign currencies. The Company purchases short-term, foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Company’s results of operations. These contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Company does not purchase foreign exchange contracts for trading purposes. The Company had foreign exchange contracts with commercial banks for British Pound Sterling, Euro, Japanese Yen, Malaysian Ringgit, Philippine Peso, Singapore Dollar and Thai Baht, which were designated as either cash flow or fair value hedges and had an aggregate notional amount of $1.5 billion and $2.0 billion at June 27, 2014 and June 28, 2013, respectively.

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 and presented within cash flow from operations. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts entered into for manufacturing-related activities are reported in cost of revenue and presented within cash flow from operations. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. The Company determined the ineffectiveness associated with its cash flow hedges to be immaterial for all years presented.

A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of operating expenses. All fair value hedges were determined to be effective. The fair value and the changes in fair value on these contracts were immaterial to the consolidated financial statements for all years presented. See Notes 10 and 12 for additional disclosures related to foreign exchange contracts.

Pensions and Other Postretirement Benefit Plans

The Company has defined benefit pension plans and other postretirement plans covering certain employees in various countries. The benefits are based on the employees’ years of service and compensation. The plans are funded in conformity with the funding requirements of applicable government authorities. The Company amortizes unrecognized actuarial gains and losses and prior service costs on a straight-line basis over the remaining estimated average service life of the participants. The measurement date for the plans is the Company’s fiscal year-end. The Company recognizes the funded status of its defined benefit pension and postretirement plans in the consolidated balance sheets, with changes in the funded status recognized through accumulated other comprehensive income (loss) in the year in which such changes occur. See Note 14 for additional disclosures related to the Company’s pension and other postretirement benefit plans.

Use of Estimates

Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates.

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The Company adopted this pronouncement in the first quarter of fiscal 2014. Since ASU 2013-02 related only to the presentation and disclosure of information, it did not have a material effect on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" ("ASU 2013-11"). The new standard requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The new standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2013, which for the Company is the first quarter of fiscal 2015. The Company does not expect the adoption of ASU 2013-11 to have a material impact on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"), which amends the guidance in former Accounting Standards Codification ("ASC") Topic 605, "Revenue Recognition", to provide a single, comprehensive revenue recognition model for all contracts with customers. The new standard requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in amounts that reflect the consideration to which an entity expects to be entitled in exchange for those goods or services. The new standard also requires entities to enhance disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new standard allows for either a full retrospective or a modified retrospective transition method and is effective for fiscal years beginning after December 15, 2016, which for the Company is the first quarter of fiscal 2018. The Company has not yet selected a transition method and is currently evaluating the impact ASU 2014-09 will have on its consolidated financial statements and related disclosures.

In April 2014, the FASB issued ASU 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"), which amends the criteria for determining which disposals can be presented as discontinued operations and enhances related disclosure requirements. Under the new guidance, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has or may have a major effect on an entity’s operations and financial results. The new standard is effective for fiscal years beginning after December 15, 2014, which for the Company is the first quarter of fiscal 2016. The Company does not expect the adoption of ASU 2014-08 to have a material impact on its consolidated financial statements.

Acquisition

Note 15. Acquisitions

Acquisition of Virident

On October 17, 2013, the Company acquired Virident, a provider of server-side flash storage solutions for virtualization, database, cloud computing and webscale applications. As a result of the acquisition, Virident has been fully integrated into the Company's HGST subsidiary and become a wholly owned indirect subsidiary of the Company. The purchase price of the acquisition was approximately $613 million, consisting of $598 million which was funded with available cash, and $15 million related to the fair value of stock options assumed. The acquisition furthered HGST's strategy to address the rapidly changing needs of enterprise customers by delivering intelligent storage solutions that maximize application performance by leveraging the tightly coupled server, storage and network resources of today’s converged datacenter infrastructures.

The Company identified and recorded the assets acquired and liabilities assumed at their estimated fair values at the date of acquisition, and allocated the remaining value of $506 million to goodwill. The values assigned to the acquired assets and liabilities were finalized as of the date of this Annual Report on Form 10-K. The individual tangible and intangible assets acquired as well as the liabilities assumed in the acquisition were immaterial to the Company's consolidated financial statements. In addition, pro forma financial information has not been presented as the acquisition did not have a material impact on the Company’s consolidated financial statements in 2014.

The final purchase price allocation for Virident was as follows (in millions):

	October 17, 2013
Tangible assets acquired and liabilities assumed	$	58
Intangible assets	49
Goodwill	506
Total	$	613

Since the date of acquisition, the Company recorded an increase of $4 million to goodwill to reflect an adjustment to the value of deferred tax assets and an adjustment to the value of investments acquired in the acquisition of Virident. The $506 million of goodwill recognized is primarily attributable to the benefits the Company expects to derive from an ability to create server-side flash storage solutions leveraging the core technology acquired and is not expected to be deductible for tax purposes. The impact to revenue and net income attributable to Virident was immaterial to the Company’s consolidated financial statements in 2014.

Acquisition of sTec

On September 12, 2013, the Company completed its acquisition of sTec, a provider of enterprise solid-state drives. As a result of the acquisition, sTec has been fully integrated into the Company's HGST subsidiary and become a wholly owned indirect subsidiary of the Company. The purchase price of the acquisition was approximately $336 million, consisting of $325 million which was funded with available cash, and $11 million related to the fair value of stock options and RSUs assumed. The acquisition augmented HGST's existing solid-state storage capabilities.

The Company identified and recorded the assets acquired and liabilities assumed at their estimated fair values at the date of acquisition, and allocated the remaining value of $89 million to goodwill. The values assigned to the acquired assets and liabilities are based on preliminary estimates of fair value available as of the date of this Annual Report on Form 10-K, and may be adjusted as further information becomes available during the measurement period of up to 12 months from the date of the acquisition. The primary areas of the preliminary purchase price allocation that are not yet finalized due to information that may become available subsequently include contingencies and income taxes, and any changes in these fair values could potentially result in material adjustments to goodwill. The individual tangible and intangible assets acquired as well as the liabilities assumed in the acquisition were immaterial to the Company's consolidated financial statements. In addition, pro forma financial information has not been presented as the acquisition did not have a material impact on the Company’s consolidated financial statements for 2014.

The preliminary purchase price allocation for sTec was as follows (in millions):

	September 12, 2013
Tangible assets acquired and liabilities assumed	$	189
Intangible assets	58
Goodwill	89
Total	$	336

Since the date of acquisition, the Company recorded a $1 million increase to goodwill to reflect an adjustment to the value of deferred tax assets acquired in the acquisition of sTec. The $89 million of goodwill recognized is primarily attributable to the benefits the Company expects to derive from augmenting HGST's existing solid-state storage capabilities and accelerating its ability to expand its participation in the growing area of enterprise solid-state drives and is not expected to be deductible for tax purposes. The impact to revenue and net income attributable to sTec was immaterial to the Company’s consolidated financial statements for 2014 .

Acquisition of VeloBit

On July 9, 2013, the Company acquired VeloBit, a privately held provider of high-performance storage I/O optimization software. As a result of the acquisition, VeloBit was fully integrated into the Company's HGST subsidiary and became a wholly owned indirect subsidiary of the Company. The acquisition built on HGST's strategy to enhance the overall value of datacenter storage by integrating HGST SSDs with software. The acquisition was not material to the Company's consolidated financial statements.

Fair Value Measurements

Note 10. Fair Value Measurements

Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three levels:

Level 1. Quoted prices in active markets for identical assets or liabilities.

Level 2. Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3. Inputs that are unobservable for the asset or liability and that are significant to the fair value of the assets or liabilities.

The following table presents information about the Company’s financial assets and liabilities that are measured at fair value on a recurring basis as of June 27, 2014, and indicates the fair value hierarchy of the valuation techniques utilized to determine such value (in millions):

Legal Proceedings

Note 5. Legal Proceedings

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

Solely for purposes of this footnote, “WD” refers to Western Digital Corporation or one or more of its subsidiaries excluding HGST prior to the HGST Closing Date. HGST refers to Hitachi Global Storage Technologies Holdings Pte. Ltd. or one or more of its subsidiaries as of the HGST Closing Date, and “the Company” refers to Western Digital Corporation and all of its subsidiaries on a consolidated basis including HGST.

Intellectual Property Litigation

On June 20, 2008, plaintiff Convolve, Inc. (“Convolve”) filed a complaint in the Eastern District of Texas against WD, HGST, and one other company alleging infringement of U.S. Patent Nos. 6,314,473 and 4,916,635. The complaint sought unspecified monetary damages and injunctive relief. On October 10, 2008, Convolve amended its complaint to allege infringement of only the ‘473 patent. The ‘473 patent allegedly relates to interface technology to select between certain modes of a disk drive’s operations relating to speed and noise. A trial in the matter began on July 18, 2011 and concluded on July 26, 2011 with a verdict against WD and HGST in an amount that is not material to the Company’s financial position, results of operations or cash flows, for which the Company previously recorded an accrual. WD and HGST have filed post-trial motions challenging the verdict. On January 17, 2014, the Court denied the Company’s motion for judgment as a matter of law on invalidity. On May 20, 2014, the Court ordered supplemental briefing related to post-trial motions related to infringement. Convolve and the Company filed their supplemental briefs on May 30, 2014 and June 6, 2014, respectively. Additional post-trial motions are pending, and the Company will evaluate its options for appeal after the Court rules on the remaining post-trial motions. The Company intends to continue to defend itself vigorously in this matter.

On December 7, 2009, plaintiff Nazomi Communications (“Nazomi”) filed a complaint in the Eastern District of Texas against WD and seven other companies alleging infringement of U.S. Patent Nos. 7,080,362 and 7,225,436. Nazomi dismissed the Eastern District of Texas suit after filing a similar complaint in the Central District of California on February 8, 2010. The case was subsequently transferred to the Northern District of California on October 14, 2010. The complaint seeks injunctive relief and unspecified monetary damages, fees and costs. The asserted patents allegedly relate to processor cores capable of Java hardware acceleration. In August 2012, the Court dismissed WD on summary judgment for non-infringement. Nazomi filed a notice of appeal on January 16, 2013. The Federal Circuit heard oral argument on the appeal on November 4, 2013 and affirmed the Court's grant of summary judgment of non-infringement on January 10, 2014. Because Nazomi did not file a petition for a writ of certiorari with the Supreme Court during the requisite time period, this matter is now closed.

On August 1, 2011, plaintiff Guzik Technical Enterprises (“Guzik”) filed a complaint in the Northern District of California against WD and various of its subsidiaries alleging infringement of U.S. Patent Nos. 6,023,145 and 6,785,085, breach of contract and misappropriation of trade secrets. The complaint seeks injunctive relief and unspecified monetary damages, fees and costs. The patents asserted by Guzik allegedly relate to devices used to test hard disk drive heads and media. On November 30, 2013, WD entered into a settlement agreement for an amount that is not material to the Company’s financial position, results of operations or cash flows, for which the Company recorded an accrual in the three months ended December 27, 2013. Guzik is disputing the enforceability of the agreement and on December 27, 2013, WD filed a motion to enforce the agreement. The Court heard oral argument on WD’s motion on January 31, 2014. The Court granted WD’s motion to enforce the settlement agreement on March 21, 2014. On April 14, 2014, Guzik filed a Notice of Appeal to the Federal Circuit. On June 17, 2014, Guzik filed its opening appellate brief. The Company filed its appellate brief on August 14, 2014. WD intends to continue to defend itself vigorously in this matter.

On July 9, 2012, Siemens Aktiengesellschaft (“Siemens”) filed a complaint in German court against WD, Western Digital GmbH, and Digital River International, S.a.r.l. alleging patent infringement of European patent no. EP 674769, which claims an artificial antiferromagnetic (AAF) (aka, synthetic antiferromagnetic) structure for magneto-resistive sensors. On March 14-15, 2013, Western Digital GmbH filed a response of non-infringement and also filed a separate nullity action. Siemens separately served WD on July 15, 2013. The patent expired on December 16, 2013 and, on March 10, 2014, Siemens withdrew its motion for injunctive relief. On February 5, 2014, the Company filed a submission in support of its nullity action. On March 25, 2014, Siemens served an extension of the complaint including WDT as a defendant. On March 28, 2014, Siemens filed its response to WD’s noninfringement submission. On June 27, 2014, WDT filed its response to the extension of the complaint. On or around July 14, 2014, Siemens filed a response to the Company’s nullity action. On July 18, 2014, the Company filed two expert opinions in support of its nullity action. Siemens has until September 5, 2014 to respond to WDT’s response to the extension of the complaint. WD’s deadline to make its last noninfringement submission is September 26, 2014. The oral hearing on infringement is scheduled for October 2, 2014. The oral hearing on the nullity action to challenge the validity of the patent is scheduled for February 3, 2015. WD intends to defend itself vigorously in this matter.

On September 5, 2013, plaintiff Lake Cherokee Hard Drive Technologies, LLC (“Lake Cherokee”) filed a complaint in the Eastern District of Texas against: Marvell Asia PTE, Ltd., Samsung Semiconductor, Inc., Seagate Tech. LLC, Seagate Tech. Int’l., Toshiba Corp., Toshiba Am. Elec. Components, Toshiba Am. Inf. Sys., Inc., Toshiba Am. Inf. Equip. (Philippines), Inc., and WDT alleging infringement of US Patent Nos. 5,844,738 and 5,978,162. Lake Cherokee alleges that WDT’s hard disk drive products that contain Marvell read channel systems-on-a-chip (SOCs) infringe its ’738 and ’162 patents. The complaint seeks unspecified monetary damages, fees and costs. On April 3, 2014, Lake Cherokee and Marvell Semiconductor, Inc. (“MSI”) engaged in mediation which resulted in a settlement-in-principle on April 8, 2014. On April 21, 2014, Lake Cherokee and MSI filed a motion to stay deadlines while the parties finalized a settlement agreement. In this motion, Lake Cherokee and MSI represented to the Court that the settlement between Lake Cherokee and MSI will result in a with-prejudice dismissal of Lake Cherokee’s claims against each of the defendants, including WDT, with respect to their sale or use of Marvell chips. On April 23, 2014, the Court granted a stay of deadlines. On June 6, 2014, Lake Cherokee and MSI participated in an arbitration hearing as to the remaining settlement agreement disputes. WDT intends to defend itself vigorously in this matter.

On September 25, 2013, plaintiff Lake Cherokee filed a complaint in the Eastern District of Texas against: Marvell Semiconductor, Inc., Marvell Asia PTE, Ltd., Dell Inc., and WDT alleging infringement of US Patent No. 5,583,706. Lake Cherokee alleges that WDT’s hard disk drive products that contain Marvell read channel systems-on-a-chip (SOCs) infringe its ’706 patent. The complaint seeks an injunction, unspecified monetary damages, fees and costs. On April 3, 2014, Lake Cherokee and MSI engaged in mediation which resulted in a settlement-in-principle on April 8, 2014. On April 21, 2014, Lake Cherokee and MSI filed a motion to stay deadlines while the parties finalized a settlement agreement. In this motion, Lake Cherokee and MSI represented to the Court that the settlement between Lake Cherokee and MSI will result in a with-prejudice dismissal of Lake Cherokee’s claims against each of the defendants, including WDT, with respect to their sale or use of Marvell chips. On April 23, 2014, the Court granted a stay of deadlines. On June 6, 2014, Lake Cherokee and MSI participated in an arbitration hearing as to the remaining settlement agreement disputes. WDT intends to defend itself vigorously in this matter.

On March 24, 2014, plaintiff Steven F. Reiber (“Reiber”) filed a complaint in the Eastern District of California against the Company, alleging infringement of U.S. Patent Nos. 7,124,927 and 7,389,905. Reiber alleges that the Company’s actions of making, using, distributing, offering for sale and selling in the United States and importing into the United States HDD heads, head gimbal assemblies, and head stack assemblies infringe the claims of the two patents at issue. The complaint seeks an injunction, unspecified monetary damages, fees and costs. Pursuant to the parties' stipulations, the Court has extended the deadline for the Company to respond to the Complaint to September 8, 2014, and set the parties' status conference for October 30, 2014. The Company intends to defend itself vigorously in this matter.

Seagate Matter

On October 4, 2006, plaintiff Seagate Technology LLC (“Seagate”) filed an action in the District Court of Hennepin County, Minnesota, naming as defendants WD and one of its now former employees previously employed by Seagate. The complaint in the action alleged claims based on supposed misappropriation of trade secrets and sought injunctive relief and unspecified monetary damages, fees and costs. On June 19, 2007, WD’s former employee filed a demand for arbitration with the American Arbitration Association. A motion to stay the litigation as against all defendants and to compel arbitration of all Seagate’s claims was granted on September 19, 2007. On September 23, 2010, Seagate filed a motion to amend its claims and add allegations based on the supposed misappropriation of additional confidential information, and the arbitrator granted Seagate’s motion. The arbitration hearing commenced on May 23, 2011 and concluded on July 11, 2011.

On November 18, 2011, the sole arbitrator ruled in favor of WD in connection with five of the eight alleged trade secrets at issue, based on evidence that such trade secrets were known publicly at the time the former employee joined WD. Based on a determination that the employee had fabricated evidence, the arbitrator then concluded that WD had to know of the fabrications. As a sanction, the arbitrator precluded any evidence or defense by WD disputing the validity, misappropriation, or use of the three remaining alleged trade secrets by WD, and entered judgment in favor of Seagate with respect to such trade secrets. Using an unjust enrichment theory of damages, the arbitrator issued an interim award against WD in the amount of $525 million plus pre-award interest at the Minnesota statutory rate of 10% per year. In his decision with respect to these three trade secrets, the arbitrator did not question the relevance, veracity or credibility of any of WD’s ten expert and fact witnesses (other than WD’s former employee), nor the authenticity of any other evidence WD presented. On January 23, 2012, the arbitrator issued a final award adding pre-award interest in the amount of $105.4 million for a total final award of $630.4 million. On January 23, 2012, WD filed a petition in the District Court of Hennepin County, Minnesota to have the final arbitration award vacated. A hearing on the petition to vacate was held on March 1, 2012.

On October 12, 2012, the District Court of Hennepin County, Minnesota vacated, in full, the $630.4 million final arbitration award. Specifically, the Court confirmed the arbitration award with respect to each of the five trade secret claims that WD and the former employee had won at the arbitration and vacated the arbitration award with respect to the three trade secret claims that WD and the former employee had lost at the arbitration. The Court ordered that a rehearing be held concerning those three alleged trade secret claims before a new arbitrator.

On October 30, 2012, Seagate initiated an appeal of the Court’s decision with the Minnesota Court of Appeals. On July 22, 2013, the Minnesota Court of Appeals reversed the District Court’s decision and remanded for entry of an order and judgment confirming the arbitration award. The Company strongly disagrees with the decision of the Court of Appeals and believes that the District Court’s decision was correct. On August 20, 2013, the Company filed a petition for review with the Minnesota Supreme Court and, on October 15, 2013, the Company was informed that the Minnesota Supreme Court granted the Company’s petition. The appeal before the Minnesota Supreme Court was fully briefed, and oral argument was held on February 5, 2014. The Company will continue to vigorously defend itself in this matter. In light of uncertainties with respect to this matter, the Company recorded an accrual of $681 million for this matter in its financial statements in the fourth quarter of fiscal 2013 and recorded additional interest totaling $52 million in 2014, which is included within charges related to arbitration award in the consolidated statements of income. This amount is in addition to the $25 million previously accrued in the fourth quarter of fiscal 2011. The total amount accrued of $758 million represents the amount of the final arbitration award, plus interest accrued on the initial arbitration award at the statutory rate of 10% from January 24, 2012 through June 27, 2014.

Other Matters

On December 22, 2011 the German Central Organization for Private Copying Rights (Zentralstelle für private Überspielungsrechte), ("ZPÜ”), an organization consisting of several levy collecting societies, submitted a pleading to the Copyright Arbitration Board (“CAB”) in Munich claiming retroactive copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce in Germany by WD from January 2008 through December 2010. The CAB was required to issue a settlement proposal within one year of the initiation of the action, failed to do so and requested the parties to consent to continue the deadline. WD declined to provide consent and, on February 1, 2013, WD filed a declaratory relief against ZPÜ in the Higher Regional Court of Munich (the “Higher Court”), seeking an order from the court to determine the copyright levy issue. On May 21, 2013, ZPÜ filed a counter-claim against WD with the Higher Court, seeking copyright levies for multimedia hard drives, external hard drives and network hard drives sold or introduced into commerce from January 2008 through December 2010 based on tariffs published by ZPÜ on November 3, 2011. On May 22, 2014, oral argument on the pleadings occurred. A decision from the Higher Court is expected by October 30, 2014, which either party may appeal. WD intends to defend itself vigorously in this matter.

In the normal course of business, the Company is subject to other legal proceedings, lawsuits and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these other matters is subject to many uncertainties and is therefore not predictable with assurance, management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations or cash flows. However, there can be no assurance with respect to such result, and monetary liability or financial impact to the Company from these other matters could differ materially from those projected.

Extraordinary and Unusual Items [Abstract]

Thailand Flooding

Note 16. Thailand Flooding

In October 2011, severe flooding in Thailand inundated all of the Company’s Thailand manufacturing facilities and submerged certain equipment located there. These facilities included the Company’s magnetic head slider fabrication facilities, as well as its hard drive, head gimbal assembly and head stack assembly facilities. As a result, the Company recorded $235 million of flood-related charges in fiscal 2012, offset by $21 million of insurance recoveries and other cost reimbursements. These charges are separately stated as a line item, “Charges related to flooding, net,” within operating expenses on the consolidated statements of income.

The Company maintains insurance coverage that provides property and business interruption coverage in the event of losses arising from flooding. The Company has submitted claims to its insurers and is awaiting a determination of how much of its total losses will be covered by insurance.

Shareholders' Equity

Note 8. Shareholders’ Equity

Stock Incentive Plans

In addition to awards assumed in connection with acquisitions, the Company maintains two stock-based incentive plans (collectively, including the assumed awards, referred to as the “Stock Plans”): the amended and restated 2004 Performance Incentive Plan and the Employee Stock Option Plan. No new awards may be granted under the Employee Stock Option Plan. As of June 27, 2014, options to purchase 77,033 shares of the Company’s common stock remained outstanding and exercisable under the Employee Stock Option Plan. Other than for such options, no restricted stock or other awards were outstanding under the Employee Stock Option Plan as of June 27, 2014. Options granted under the Employee Stock Option Plan expire ten years from the date of grant.

The types of awards that may be granted under the 2004 Performance Incentive Plan include stock options, SARs, RSUs, stock bonuses and other forms of awards granted or denominated in the Company’s common stock or units of the Company’s common stock, as well as cash bonus awards. Persons eligible to receive awards under the 2004 Performance Incentive Plan include officers and employees of the Company or any of its subsidiaries, directors of the Company and certain consultants and advisors to the Company or any of its subsidiaries. The vesting of awards under the 2004 Performance Incentive Plan is determined at the date of grant. Each award expires on a date determined at the date of grant; however, the maximum term of options and SARs under the 2004 Performance Incentive Plan is ten years after the grant date of the award. RSUs granted under the 2004 Performance Incentive Plan typically vest over periods ranging from one to four years from the date of grant. To the extent available, the Company issues shares out of treasury stock upon the vesting of awards or the exercise of employee stock options and ESPP.

As of June 27, 2014, the maximum number of shares of the Company’s common stock that was authorized for award grants under the 2004 Performance Incentive Plan was 48.8 million shares. Any shares subject to awards under the Employee Stock Option Plan that are canceled, forfeited or otherwise terminate without having vested or been exercised, as applicable, will become available for other award grants under the 2004 Performance Incentive Plan. Shares issued in respect of stock options and SARs granted under the 2004 Performance Incentive Plan count against the plan’s share limit on a one-for-one basis, whereas shares issued in respect of any other type of award granted through November 7, 2012 under the plan count against the plan’s share limit as 1.35 shares for every one share actually issued in connection with such award. Shares issued in respect of awards granted on or after November 8, 2012 count against the plan’s share limit as 1.72 shares for every one share actually issued in connection with such award. The 2004 Performance Incentive Plan was extended in 2013 and will terminate on August 6, 2022 unless terminated earlier by the Company’s Board of Directors.

Employee Stock Purchase Plan

The Company maintains an ESPP. Under the ESPP, eligible employees may authorize payroll deductions of up to 10% of their eligible compensation during prescribed offering periods to purchase shares of the Company’s common stock at 95% of the fair market value of common stock on either the first day of that offering period or on the applicable exercise date, whichever is less. A participant may participate in only one offering period at a time, and a new offering period generally begins each June 1st and December 1st. Each offering period is generally 24 months and consists of four exercise dates (each, generally six months following the start of the offering period or the preceding exercise date, as the case may be). If the fair market value of the Company’s common stock is less on a given exercise date than on the date of grant, employee participation in that offering period ends and participants are automatically re-enrolled in the next new offering period.

Stock-based Compensation Expense

The Company recognized in expense $85 million, $88 million and $57 million for stock-based compensation related to the vesting of options issued by the Company under the Stock Plans and the ESPP in 2014, 2013 and 2012, respectively. The tax benefit realized as a result of the aforementioned stock-based compensation expense was $22 million, $25 million and $12 million in 2014, 2013 and 2012, respectively. As of June 27, 2014, total compensation cost related to unvested stock options granted under the Stock Plans and ESPP rights issued to employees but not yet recognized was $128 million and will be amortized on a straight-line basis over a weighted average service period of approximately 2.2 years.

For purposes of this footnote, references to RSUs include performance stock unit awards (“PSUs”). The effect of the PSU activity was immaterial to the consolidated financial statements in 2014, 2013 and 2012. The Company granted approximately 1.4 million RSUs during 2014, which are generally payable in an equal number of shares of the Company’s common stock at the time of vesting of the units. The aggregate market value of the shares underlying the RSUs granted in 2014 was $95 million at the date of grant. The compensation expense for granted and assumed RSUs is being recognized as expense over the corresponding vesting or measurement periods of the awards. For purposes of recognizing awards granted, the Company has assumed a weighted average forfeiture rate of 3.3% based on a historical analysis indicating forfeitures for these types of awards. The Company recognized in expense $71 million, $52 million and $35 million related to RSUs granted under the Stock Plans that vested during 2014, 2013 and 2012, respectively. The tax benefit realized as a result of the aforementioned expense was $18 million, $14 million and $10 million in 2014, 2013 and 2012, respectively. As of June 27, 2014, the aggregate unamortized fair value of all unvested RSUs granted under the Stock Plans was $91 million, which will be recognized on a straight-line basis over a weighted average vesting period of approximately 1.4 years. In 2013, stock-based compensation expense included $5 million of accelerated expense associated with the employee termination benefits as discussed in Note 17.

The Company recognized in expense $36 million and $46 million related to adjustments to market value as well as the vesting of SARs in 2014 and 2013, respectively, and a benefit of $7 million related to SARs in 2012. The tax benefit realized as a result of the aforementioned SARs expense was $7 million and $4 million in 2014 and 2013, respectively. There was no tax effect in 2012. The SARs will be settled in cash upon exercise. As a result, the Company had a total liability of $61 million related to SARs included in accrued liabilities as of June 27, 2014 in the consolidated balance sheet. As of June 27, 2014, total compensation cost related to unvested SARs issued to employees but not yet recognized was $1 million and will be recognized on a straight-line basis over a weighted average service period of approximately 0.5 years.

Stock Option Activity

The following table summarizes stock option activity under the Stock Plans over the last three fiscal years (in millions, except per share amounts and remaining contractual lives):

	Number of Shares		Weighted Average Exercise Price Per Share		Weighted Average Remaining Contractual Life (in years)	Aggregate Intrinsic Value
Options outstanding at July 1, 2011	10.2		$	22.49

Vested and expected to vest after June 27, 2014	9.9		$	36.82	4.5	$	565

If an option has an exercise price that is less than the quoted price of the Company’s common stock at the particular time, the aggregate intrinsic value of that option at that time is calculated based on the difference between the exercise price of the underlying options and the quoted price of the Company’s common stock at that time. As of June 27, 2014, the Company had options outstanding to purchase an aggregate of 10.0 million shares with an exercise price below the quoted price of the Company’s stock on that date resulting in an aggregate intrinsic value of $572 million at that date. During 2014, 2013 and 2012, the aggregate intrinsic value of options exercised under the Stock Plans was $247 million, $211 million and $53 million, respectively, determined as of the date of exercise.

The following table summarizes information about options outstanding and exercisable under the Stock Plans as of June 27, 2014 (in millions, except exercise price):

	Options Outstanding				Options Exercisable
Range of Exercise Prices	Number of Shares	Weighted Average Remaining Contractual Life (in years)	Weighted Average Exercise Price		Number of Shares	Weighted Average Exercise Price
$3.08 – $23.78	2.5	4.7	$	13.41	1.6	$	13.79

RSU Activity

The following table summarizes RSU activity (in millions, except weighted average grant date fair value):

	Number of Shares		Weighted Average Grant Date Fair Value
RSUs outstanding at July 1, 2011	3.1		$	28.85
Granted	1.6		32.87
Assumed	0.4		38.98
Vested	(1.3	)	24.58
Forfeited or expired	(0.1	)	32.01
RSUs outstanding at June 29, 2012	3.7		$	33.19
Granted	1.7		43.14
Vested	(1.4	)	37.89
Forfeited or expired	(0.4	)	35.46
RSUs outstanding at June 28, 2013	3.6		$	35.82

Assumed	0.2		62.73
Vested	(1.3	)	33.61
Forfeited or expired	(0.2	)	47.62
RSUs outstanding at June 27, 2014	3.7		$	49.77
Expected to vest after June 27, 2014	3.5		$	49.48

The fair value of each RSU is the market price of the Company’s stock on the date of grant. RSUs are generally payable in an equal number of shares of the Company’s common stock at the time of the vesting of the units. The aggregate value of RSUs that became fully-vested during 2014, 2013 and 2012 was $89 million, $71 million and $41 million, respectively, determined as of the vest date. The grant-date fair value of the shares underlying the RSU awards at the date of grant or assumption was $95 million, $74 million and $71 million in 2014, 2013 and 2012, respectively. These amounts are being recognized to expense over the corresponding vesting periods. For purposes of valuing these awards, the Company has assumed a forfeiture rate of 3.3%, 2.0% and 2.4% during 2014, 2013 and 2012, respectively, based on a historical analysis indicating forfeitures for these types of awards.

SARs Activity

The share-based compensation liability for SARs is recognized for the portion of fair value for which service has been rendered at the reporting date. The share-based liability is remeasured at each reporting date, using a binomial option-pricing model, through the requisite service period. As of June 27, 2014, 0.7 million SARs were outstanding with a weighted average exercise price of $7.96. There were no SARs granted and all other SARs activity was immaterial to the consolidated financial statements for the year ended June 27, 2014.

Fair Value Disclosure — Binomial Model

The fair value of stock options granted is estimated using a binomial option-pricing model. The binomial model requires the input of highly subjective assumptions. The Company uses historical data to estimate exercise, employee termination, and expected stock price volatility within the binomial model. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The fair value of stock options granted during the three years ended June 27, 2014 was estimated using the following weighted average assumptions:

	2014	2013	2012
Suboptimal exercise factor	2.07	1.90	1.81
Range of risk-free interest rates	0.10% to 2.44%	0.14% to 1.96%	0.12% to 1.61%
Range of expected stock price volatility	0.27 to 0.50	0.36 to 0.53	0.41 to 0.55
Weighted average expected volatility	0.43	0.49	0.49
Post-vesting termination rate	3.10%	2.16%	2.61%
Dividend yield	1.58%	2.53%	—
Fair value	$24.14	$15.75	$12.91

The weighted average expected term of the Company’s stock options granted during 2014, 2013 and 2012 was 5.0 years, 4.0 years and 4.9 years, respectively.

Fair Value Disclosure — Black-Scholes-Merton Model

The fair value of ESPP purchase rights issued is estimated at the date of grant of the purchase rights using the Black-Scholes-Merton option-pricing model. The Black-Scholes-Merton option-pricing model requires the input of highly subjective assumptions such as the expected stock price volatility and the expected period until options are exercised. Purchase rights under the ESPP are granted on either June 1st or December 1st of each year.

The fair values of all ESPP purchase rights granted on or prior to June 27, 2014 have been estimated at the date of grant using a Black-Scholes-Merton option-pricing model with the following weighted average assumptions:

	ESPP
	2014	2013	2012
Option life (in years)	1.24	1.24	1.24
Risk-free interest rate	0.26%	0.23%	0.22%
Stock price volatility	0.31	0.42	0.46
Dividend yield	1.64%	1.61%	—
Fair value	$14.62	$10.36	$7.29

Stock Repurchase Program

Since May 18, 2012, the Company's Board of Directors has authorized $3.0 billion for the repurchase of its common stock until September 13, 2017. The Company repurchased 10.3 million shares for a total cost of $816 million during 2014. The remaining amount available to be purchased under the Company’s stock repurchase program as of June 27, 2014 was $1.2 billion. The Company may continue to repurchase its stock as it deems appropriate and market conditions allow. Repurchases under the stock repurchase program may be made in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. The Company expects stock repurchases to be funded principally by operating cash flows and borrowings under the Credit Agreement.

Stock Reserved for Issuance

The following table summarizes all shares of common stock reserved for issuance at June 27, 2014 (in millions):

	Number of Shares
Maximum shares issuable in connection with:
Outstanding awards and shares available for award grants	23.6

Total	29.5

Dividends to Shareholders

On September 13, 2012, the Company announced that its Board of Directors had authorized the adoption of a quarterly cash dividend policy. Under the cash dividend policy, holders of the Company’s common stock receive dividends when and as declared by the Company’s Board of Directors. In 2014, the Company declared aggregate cash dividends of $1.25 per share of the Company’s common stock, totaling $295 million, of which $201 million was paid during 2014. On August 5, 2014, the Company declared a cash dividend of $0.40 per share of its common stock to shareholders of record as of October 3, 2014, which will be paid on October 15, 2014. The Company may modify, suspend or cancel its cash dividend policy in any manner and at any time.

Western Digital Corporation 401(k) Plan

Note 7. Western Digital Corporation 401(k) Plan

The Company has adopted the Western Digital Corporation 401(k) Plan (the “Plan”). The Plan covers substantially all domestic employees, subject to certain eligibility requirements. The Company makes a basic matching contribution on behalf of each participating eligible employee equal to fifty percent (50%) of the eligible participant’s pre-tax contributions for the contribution cycle not to exceed 5% of the eligible participant’s compensation; provided, however, that each eligible participant shall receive a minimum annual basic matching contribution equal to fifty percent (50%) of the first $4,000 of pre-tax contributions for any calendar year. The Plan was amended effective January 1, 2013, to provide for a year-end true-up matching contribution such that participants who save at least 5% of their eligible compensation for the year receive a minimum annual matching contribution equal to 2.5% of eligible compensation (up to Internal Revenue Service (“IRS”) limitations). Company contributions vest over a 5-year period of employment. For 2014, 2013, and 2012, the Company made Plan contributions of $21 million, $19 million and $12 million, respectively.

Income Taxes

Note 9. Income Taxes

Pre-tax Income

The domestic and foreign components of income before income taxes were as follows for the three years ended June 27, 2014 (in millions):

	2014		2013		2012
Foreign	$	1,664	$	870	$	1,559
Domestic	88		352		198
Income before income taxes	$	1,752	$	1,222	$	1,757

Income Tax Provision

The components of the provision for income taxes were as follows for the three years ended June 27, 2014 (in millions):

	2014			2013			2012
Current:
Foreign	$	47		$	57		$	12
Domestic-federal	98			149			98
Domestic-state	3			1			1
Deferred:
Foreign	(3		)	(7		)	18
Domestic-federal	(14		)	(46		)	25
Domestic-state	4			88			(9		)
Income tax provision	$	135		$	242		$	145

The Company’s income tax provision for 2013 reflects a tax benefit of $37 million as a result of the retroactive extension of the U.S. Federal research and experimentation tax credit (“R&D credit”) that was signed into law on January 2, 2013 as part of the American Taxpayer Relief Act of 2012. The R&D credit, which had previously expired on December 31, 2011, was extended through December 31, 2013. In addition, the Company recorded an $88 million charge to reduce its previously recognized California deferred tax assets in 2013 as a result of the enactment of California Proposition 39.

Remaining net undistributed earnings from foreign subsidiaries at June 27, 2014 on which no U.S. tax has been provided amounted to $8.2 billion. The net undistributed earnings are intended to finance local operating requirements and capital investments. Accordingly, an additional U.S. tax provision has not been made on these earnings. The tax liability for these earnings would be $2.7 billion if the Company repatriated the $8.2 billion in undistributed earnings from the foreign subsidiaries.

Deferred Taxes

Temporary differences and carryforwards, which give rise to a significant portion of deferred tax assets and liabilities as of June 27, 2014 and June 28, 2013 were as follows (in millions):

	2014			2013
Deferred tax assets:
Sales related reserves and accrued expenses not currently deductible	$	38		$	45
Accrued compensation and benefits not currently deductible	190			182
Domestic net operating loss carryforward	130			103
Business credit carryforward	155			123
Long-lived assets	58			47
Other	65			71
Total deferred tax assets	636			571
Deferred tax liabilities:
Long-lived assets	(152		)	(156		)
Other	(11		)	—
Total deferred tax liabilities	(163		)	(156		)
Valuation allowances	(128		)	(133		)
Deferred tax assets, net	$	345		$	282
Deferred tax assets:
Current portion (included in other current assets)	$	184		$	160
Non-current portion (included in other non-current assets)	452			411
Total deferred tax assets	636			571
Deferred tax liabilities:
Current portion (included in other current assets)	(2		)	—
Non-current portion (included in other non-current assets)	(161		)	(156		)
Total deferred tax liabilities	(163		)	(156		)
Valuation allowances (included in non-current portion of deferred tax assets)	(128		)	(133		)
Deferred tax assets, net	$	345		$	282

The net deferred tax asset valuation allowance was $128 million as of June 27, 2014. The valuation allowance is based on the Company’s assessment that it is more likely than not that certain deferred tax assets will not be realized in the foreseeable future.

In addition to the deferred tax assets presented above, the Company had additional NOL benefits related to stock-based compensation deductions of $11 million and $13 million at June 27, 2014 and June 28, 2013, respectively. During the current year, the Company generated an additional $66 million of benefits related to stock-based compensation deductions, of which $60 million were utilized in the current year and recorded as a credit to shareholder's equity.

Effective Tax Rate

Reconciliation of the U.S. Federal statutory rate to the Company’s effective tax rate is as follows for the three years ended June 27, 2014:

	2014		2013		2012
U.S. Federal statutory rate	35	%	35	%	35	%
Tax rate differential on international income	(28	)	(19	)	(29	)
Tax effect of U.S. permanent differences	2		—		3
State income tax, net of federal tax	—		8		1
Income tax credits	(1	)	(4	)	(2	)
Effective tax rate	8	%	20	%	8	%

Tax Holidays and Carryforwards

A substantial portion of the Company’s manufacturing operations in Malaysia, the Philippines, Singapore and Thailand operate under various tax holidays and tax incentive programs which will expire in whole or in part at various dates from 2015 through 2025. Certain of the holidays may be extended if specific conditions are met. The net impact of these tax holidays and tax incentives was to increase the Company’s net earnings by $905 million ($3.74 per diluted share), $899 million ($3.65 per diluted share), and $729 million ($2.98 per diluted share) in 2014, 2013 and 2012, respectively.

As of June 27, 2014, the Company had federal and state NOL carryforwards of $440 million and $480 million, respectively. In addition, as of June 27, 2014, the Company had various federal and state tax credit carryforwards of $331 million combined. The NOL carryforwards available to offset future federal and state taxable income expire at various dates from 2020 to 2032 and 2017 to 2032, respectively. Approximately $50 million of the credit carryforwards available to offset future taxable income expire at various dates from 2016 to 2033. The remaining amount is available indefinitely. NOLs and credits relating to Komag, Incorporated (“Komag”), which was acquired by the Company on September 5, 2007, HGST, sTec and Virident are subject to limitations under Sections 382 and 383 of the Internal Revenue Code. The Company does not expect these limitations to result in a reduction in the total amount of Komag, sTec or Virident's NOLs and credits ultimately realized. The Company expects the total amount of HGST’s NOLs and credits ultimately realized will be reduced by $39 million and $25 million, respectively. Because the Company expects the amount of HGST’s NOLs and credits ultimately realized will be reduced, the Company has adjusted goodwill accordingly.

Uncertain Tax Positions

The Company recognizes liabilities for uncertain tax positions based on a two-step process. First, the tax position is evaluated for recognition by determining if it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. If the tax position is deemed more-likely-than-not to be sustained, the tax position is then assessed to determine the amount of benefit to be recognized in the financial statements. The amount of the benefit that may be recognized is the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. With the exception of certain unrecognized tax benefits that are directly associated with the tax position taken, unrecognized tax benefits are presented gross in the Company’s balance sheet. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. As of June 27, 2014, such interest and penalties were not material. As of June 27, 2014, the Company had $300 million of unrecognized tax benefits.

The following is a tabular reconciliation of the total amounts of unrecognized tax benefits for the years ended June 27, 2014, June 28, 2013 and June 29, 2012 (in millions):

	2014			2013			2012
Unrecognized tax benefit at beginning of period	$	240		$	280		$	245
Gross increases related to current year tax positions	27			29			14
Gross increases related to prior year tax positions	26			10			—
Gross decreases related to prior year tax positions	(5		)	(8		)	—
Settlements	—			(64		)	(18		)
Lapse of statute of limitations	—			(7		)	—
Acquisitions	12			—			39
Unrecognized tax benefit at end of period	$	300		$	240		$	280

The Company’s unrecognized tax benefits are primarily included within long-term liabilities in the Company’s consolidated balance sheets. The entire balance of unrecognized tax benefits at June 27, 2014, June 28, 2013 and June 29, 2012, if recognized, would affect the effective tax rate.

The Company files U.S. Federal, U.S. state, and foreign tax returns. For both federal and state tax returns, with few exceptions, the Company is subject to examination for fiscal years 2008 through 2013. In foreign jurisdictions, with few exceptions, the Company is subject to examination for all years subsequent to fiscal 2007. The Company is no longer subject to examination by the IRS for periods prior to 2008, although carry forwards generated prior to those periods may still be adjusted upon examination by the IRS or state taxing authority if they either have been or will be used in a subsequent period.

The IRS previously completed its field examination of the Company’s federal income tax returns for fiscal years 2006 and 2007 and issued Revenue Agent Reports that proposed adjustments to income before income taxes of approximately $970 million primarily related to transfer pricing and intercompany payable balances. The Company disagreed with the proposed adjustments and filed a protest with the IRS Appeals Office. In June 2013, the Company reached an agreement with the IRS to resolve the transfer pricing issue. This agreement resulted in a decrease in the amount of net operating loss and tax credits realized, but did not have an impact to the Company’s consolidated statements of income. The proposed adjustment relating to intercompany payable balances for fiscal years 2006 and 2007 will be addressed in conjunction with the IRS’s examination of the Company’s fiscal years 2008 and 2009, which commenced in January 2012. In addition, in January 2012, the IRS commenced an examination of the 2007 fiscal period ended September 5, 2007 of Komag. In February 2013, the IRS commenced an examination of calendar years 2010 and 2011 of HGST, which was acquired by the Company on March 8, 2012.

The Company believes that adequate provision has been made for any adjustments that may result from tax examinations. However, the outcome of tax audits cannot be predicted with certainty. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. As of June 27, 2014, it is not possible to estimate the amount of change, if any, in the unrecognized tax benefits that is reasonably possible within the next twelve months. Any significant change in the amount of the Company’s liability for unrecognized tax benefits would most likely result from additional information or settlements relating to the examination of the Company’s tax returns.

_____________________

⁽¹⁾   During fiscal 2014 the Japan entity assumed benefit obligations and plan assets from Hitachi. These pension obligations related to former Hitachi employees who were hired into the HGST Japan entity during or soon after the 2012 acquisition of HGST by the Company.

The following table presents the unfunded amounts as recognized on the Company’s consolidated balance sheets as of June 27, 2014 and June 28, 2013 (in millions):

	2014		2013
Current liabilities	$	1	$	1
Non-current liabilities	63		66
Net amount recognized	$	64	$	67

The accumulated benefit obligation for the Japanese defined benefit pension plans was $255 million at June 27, 2014. As of June 27, 2014, net actuarial losses for the Japanese defined benefit pension plans of $10 million are included in accumulated other comprehensive income (loss) in the consolidated balance. There were no prior service credits for the defined benefit pension plans recognized in accumulated other comprehensive income (loss) in the consolidated balance sheet as of June 27, 2014. The amount expected to be amortized into net periodic benefit cost in fiscal 2015 is immaterial to the consolidated financial statements.

Assumptions

Weighted-Average Assumptions

The weighted-average actuarial assumptions used to determine benefit obligations for the Japanese defined benefit pension plans were as follows for 2014, 2013 and 2012:

	2014		2013		2012
Discount rate	1.6	%	1.6	%	1.8	%
Rate of compensation increase	1.0	%	0.9	%	1.4	%

The weighted-average actuarial assumptions used to determine benefit costs for the Japanese defined benefit pension plans were as follows for 2014, 2013 and 2012:

	2014		2013		2012
Discount rate	1.6	%	1.8	%	1.9	%
Expected long-term rate of return on plan assets	3.5	%	3.5	%	3.5	%
Rate of compensation increase	0.9	%	1.2	%	1.4	%

The Company develops a discount rate by calculating when the estimated benefit payments will be due. Management in Japan then matches the benefit payments to AA or higher bond ratings that match the timing of the expected benefit payments to determine the appropriate discount rate.

The Company develops the expected long-term rate of return on plan assets by analyzing rates of return in Japan as well as the investment portfolio applicable to the plan. Management’s estimates of future rates of return on assets is based in large part on the projected rate of return from the respective investment managers using a long-term view of historical returns, as well as actuarial recommendations using the most current generational and mortality tables and rates.

The Company develops the rate of compensation increase assumptions using local compensation practices and historical rates of increases.

Plan Assets

Investment Policies and Strategies

The investment policy in Japan is to generate a stable return on investments over a long-term horizon in order to have adequate pension funds to meet the Company’s future obligations. In order to achieve this investment goal, a diversified portfolio with target asset allocation and expected rate of return is established by considering factors such as composition of participants, level of funded status, capacity to absorb risks, and the current economic environment. The target asset allocation is 35% in equity securities, 62% in debt securities and the remaining 3% in other assets. Risk management is accomplished through diversification, periodic review of plan asset performance, and appropriate realignment of asset allocation. Assumptions regarding the expected long-term rate of return on plan assets are periodically reviewed and are based on the historical trend of returns, the risk and correlation of each asset, and the latest economic environment.

The expected long-term rate of return is estimated based on many factors, including expected forecast for inflation, risk premiums for each asset class, expected asset allocation, current and future financial market conditions, and diversification and rebalancing strategies. Historical return patterns and correlations, consensus return forecasts, and other relevant financial factors are analyzed periodically by the investment advisor so as to ensure that the expected long-term rate of return is reasonable and appropriate.

Assets held in defined benefit plans in the Philippines, Taiwan and Thailand were less than $1 million and are not presented in the above table. There were no significant movements of assets between any level categories in 2014, 2013 or 2012.

Fair Value Valuation Techniques

Equity securities are valued at the closing price reported on the stock exchange on which the individual securities are traded. Equity commingled/mutual funds are typically valued using the net asset value (“NAV”) provided by the investment manager or administrator of the fund. The NAV is based on the value of the underlying assets owned by the fund, minus liabilities and divided by the number of shares or units outstanding. These assets are classified as either Level 1 or Level 2, depending on availability of quoted market prices for identical or similar assets.

If available, fixed income securities are valued using the close price reported on the major market on which the individual securities are traded and are classified as Level 1. The fair value of other fixed income securities is typically estimated using pricing models and quoted prices of securities with similar characteristics, and is generally classified as Level 2.

Cash includes money market accounts that are valued at their cost plus interest on a daily basis, which approximates fair value. Short-term investments represent securities with original maturities of one year or less. These assets are classified as either Level 1 or Level 2.

Cash Flows

Contributions

The Company’s expected employer contributions for 2015 are $14 million for its Japanese defined benefit pension plans.

Estimated Future Benefits Payments

Annual benefit payments from the Japanese defined benefit pension plans are estimated to range from $7 million to $11 million annually over the next five years.

Long-term debt	$	2,313		$	1,725

On March 8, 2012 (the “HGST Closing Date”), the Company, in its capacity as the parent entity and guarantor, Western Digital Technologies, Inc. (“WDT”), a wholly owned subsidiary of the Company, and Western Digital Ireland, Ltd. (“WDI”), an indirect wholly owned subsidiary of the Company, entered into a five-year credit agreement (the “Prior Credit Facility”) with Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer, and certain other participating lenders. The Prior Credit Facility provided for $2.8 billion of unsecured loan facilities consisting of a $2.3 billion term loan facility and a $500 million revolving credit facility. On January 9, 2014, WDI used existing cash to repay the outstanding term loan balance of $1.8 billion under the Prior Credit Facility, and the Company, WDT and WDI, entered into a new credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto (the "Credit Agreement"); WDT paid the outstanding revolving credit facility balance of $500 million under the Prior Credit Facility; and the Company terminated the Prior Credit Facility. In connection with the repayment of the Prior Credit Facility, $4 million of debt issuance costs associated with lenders that extinguished or reduced their participation in the Credit Agreement were written off in fiscal 2014, and are included within interest and other expense in the consolidated statements of income. The Credit Agreement provides for $4.0 billion of unsecured loan facilities consisting of a $2.5 billion term loan facility to WDT and a $1.5 billion revolving credit facility to WDT and WDI (the “Borrowers”). The revolving credit facility includes a $100 million sublimit for letters of credit and a $50 million sublimit for swing line loans. Subject to certain conditions, a Borrower may elect to expand the credit facilities by, or obtain incremental term loans of, up to $1.0 billion if existing or new lenders provide additional term or revolving commitments. The loans under the Credit Agreement have a five-year term. The obligations of the Borrowers under the Credit Agreement are guaranteed by the Company and its material domestic subsidiaries, and the obligations of WDI under the Credit Agreement are also guaranteed by WDT.

The term loans and the revolving credit loans may be prepaid in whole or in part at any time without premium or penalty, subject to certain conditions. As of June 27, 2014, no amounts were outstanding under the revolving credit facility and the term loan facility had a variable interest rate of 1.7% and a remaining, outstanding balance of $2.4 billion. The Company is required to make quarterly principal payments on the term loan facility totaling $125 million in fiscal 2015, $156 million in fiscal 2016, $219 million in fiscal 2017, $250 million in fiscal 2018 and the remaining balance of $1.7 billion in fiscal 2019.

The Credit Agreement requires the Company 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 Agreement contains customary covenants, including covenants that limit or restrict the Company’s and its subsidiaries’ ability to incur liens, incur indebtedness, make certain restricted payments, merge or consolidate and enter into certain speculative hedging arrangements, and customary events of default. As of June 27, 2014, the Company was in compliance with all covenants.

Organization and Summary of Significant Accounting Policies (Policies)

12 Months Ended

Jun. 27, 2014

Accounting Policies [Abstract]

Fiscal Year

Fiscal Year

The Company has a 52 or 53-week fiscal year. The 2014, 2013 and 2012 fiscal years which ended on June 27, 2014, June 28, 2013 and June 29, 2012, respectively, consisted of 52 weeks each.

Basis of Presentation

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In fiscal 2014 and fiscal 2013, the accounts for all foreign subsidiaries have been remeasured using the U.S. dollar as the functional currency. In fiscal 2012, the accounts for all foreign subsidiaries, except for one Japanese subsidiary in which Yen was the functional currency, have been remeasured using the U.S. dollar as the functional currency. Gains or losses resulting from remeasurement or translation of these accounts from local currencies into U.S. dollars were immaterial to the consolidated financial statements.

The Company acquired Virident Systems, Inc. ("Virident") on October 17, 2013, sTec, Inc. (“sTec”) on September 12, 2013, and VeloBit, Inc. ("VeloBit") on July 9, 2013. In addition, on March 8, 2012, the Company completed its acquisition of all of the issued and paid-up share capital of Viviti Technologies Ltd., known until shortly before acquisition as Hitachi Global Storage Technologies Holdings Pte. Ltd. (“HGST”), from Hitachi, Ltd. (“Hitachi”). These acquisitions are further described in Note 15 below. In connection with the acquisitions, Virident, sTec, VeloBit and HGST became indirect wholly-owned subsidiaries of the Company. The results of operations of Virident, sTec, VeloBit and HGST since the respective dates of acquisition are included in the consolidated financial statements

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company’s cash equivalents represent highly liquid investments in money market funds, which are invested in U.S. Treasury securities and U.S. Government agency securities as well as direct investments in bank acceptances with original maturities when purchased of three months or less. Cash equivalents are carried at cost, which approximates fair value.

Investments

Investments

The Company's investments in U.S. Treasury securities, U.S. Government agency securities, commercial paper and certificates of deposit with original maturities at purchase of more than three months. These investments are classified as available-for-sale securities and included within short-term investments and other non-current assets in the consolidated balance sheets. Available-for-sale securities are stated at fair value with unrealized gains and losses included in accumulated other comprehensive income (loss), which is a component of shareholders' equity. The Company evaluates the available-for sale securities in an unrealized loss position for other-than-temporary impairment. The amortized cost of available-for-sale securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion are included in interest and other income and other in the consolidated statements of income. In addition, realized gains and losses are included in total other expense, net in the consolidated statements of income.

In addition, the Company enters into certain strategic investments for the promotion of business and strategic objectives. These strategic investments are recorded at cost within other non-current assets in the consolidated balance sheets and are periodically analyzed to determine whether or not there are indicators of impairment. Lastly, the Company’s investments included auction-rate securities which were all sold during 2014. The Company's auction rate securities were classified as available-for-sale securities and carried at fair value within other non-current assets in the consolidated balance sheets.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts of cash equivalents, accounts receivable, investments, accounts payable and accrued expenses approximate fair value for all periods presented because of the short-term maturity of these assets and liabilities or, in the case of investments, these are recorded using appropriate market information. The carrying amount of debt approximates fair value because of its variable interest rate.

Concentration of Credit Risk

Concentration of Credit Risk

The Company sells its products to computer manufacturers, resellers and retailers throughout the world. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. The Company maintains allowances for potential credit losses, and such losses have historically been within management’s expectations. At any given point in time, the total amount outstanding from any one of a number of its customers may be individually significant to the Company’s financial results. At June 27, 2014 and June 28, 2013, the Company had two customers that accounted for 29% of the Company's net accounts receivable. At June 27, 2014 and June 28, 2013, the Company had reserves for potential credit losses of $11 million and $9 million, respectively, and net accounts receivable of $2.0 billion and $1.8 billion at each date, 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.

Inventories

Inventories

The Company values inventories at the lower of cost (first-in, first out and weighted average methods) or net realizable value. The first-in, first-out (“FIFO”) method is used to value the cost of the majority of the Company’s inventories, while the weighted-average method is used to value precious metal inventories. Weighted-average cost is calculated based upon the cost of precious metals at the time they are received by the Company. The Company has determined that it is not practicable to assign specific costs to individual units of precious metals and, as such, precious metals are relieved from inventory based on the weighted-average cost of the inventory at the time the inventory is used in production. The weighted average method of valuing precious metals does not materially differ from a FIFO method. As of June 27, 2014 and June 28, 2013, 92% and 91%, 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 the Company’s products, which may require a write down of inventory that could materially affect operating results.

Property, Plant and Equipment

Property, Plant and Equipment

The cost of property, plant and equipment is depreciated over the estimated useful lives of the respective assets. The Company’s buildings are depreciated over periods ranging from fifteen to thirty years. The majority of the Company’s equipment is depreciated over periods of two to seven years. Depreciation is computed on a straight-line basis. Leasehold improvements are amortized over the lesser of the estimated useful lives of the assets or the related lease terms.

Goodwill and Other Long-Lived Assets

Goodwill and Other Long-Lived Assets

The fair value of assets acquired and liabilities assumed in a business acquisition are recognized at the acquisition date, with amounts exceeding the fair values being recognized as goodwill. Goodwill is not amortized. Instead, it is tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that goodwill may be impaired. The Company performs its annual impairment test as of the first day of its fiscal fourth quarter. The Company either uses qualitative factors to determine whether goodwill is more likely than not impaired or performs a two-step approach to quantify impairment. If the Company concludes from the qualitative assessment that goodwill is more likely than not impaired, it is required to follow a two-step approach to quantify the impairment. The Company is required to use judgment when applying the goodwill impairment test, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. In addition, the estimates used to determine the fair value of each reporting unit may change based on results of operations, macroeconomic conditions or other factors. Changes in these estimates could materially affect the Company’s assessment of the fair value and goodwill impairment for each reporting unit. The Company did not record any impairment of goodwill during 2014, 2013, or 2012.

Other intangible assets consist primarily of technology acquired in business combinations and in-process research and development. In-process research and development is not amortized until the point at which it reaches technological feasibility. Instead, it is instead tested for impairment on an annual basis or more frequently whenever events or changes in circumstances indicate that it may be impaired. Acquired intangibles are amortized on a straight-line basis over their respective estimated useful lives. Long-lived assets are tested for recoverability whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. If impairment is indicated, the impairment is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The Company recorded impairments to certain long-lived assets in 2014, 2013 and 2012. See Notes 13 and 17.

Revenue and Accounts Receivable

Revenue and Accounts Receivable

Revenue is recognized when the title and risk of loss have passed to the customer, there is persuasive evidence of an arrangement, delivery has occurred, or services have been rendered, the sales price is fixed or determinable and collectability is reasonably assured. The Company establishes provisions against revenue and cost of revenue for estimated sales returns in the same period that the related revenue is recognized based on existing product return notifications. If actual sales returns exceed expectations, an increase in the sales return accrual would be required, which could materially affect operating results.

In accordance with standard industry practice, the Company provides distributors and retailers (collectively referred to as “resellers”) with limited price protection for inventories held by resellers at the time of published list price reductions, and the Company provides resellers and OEMs with other sales incentive programs. At the time the Company recognizes revenue to resellers and OEMs, a reduction of revenue is recorded for estimated price protection until the resellers sell such inventory to their customers and the Company also records a reduction of revenue for the other programs in effect. The Company bases these adjustments on several factors including anticipated price decreases during the reseller holding period, reseller’s sell-through and inventory levels, estimated amounts to be reimbursed to qualifying customers, historical pricing information and customer claim processing. If customer demand for the Company's products or market conditions differ from the Company’s expectations, the Company’s operating results could be materially affected. The Company also has programs under which it reimburses qualified distributors and retailers for certain marketing expenditures, which are recorded as a reduction of revenue. Customer sales incentive and marketing programs are recorded as a reduction of revenue.

The Company records an allowance for doubtful accounts by analyzing specific customer accounts and assessing the risk of loss based on insolvency, disputes or other collection issues. In addition, the Company routinely analyzes the different receivable aging categories and establishes reserves based on a combination of past due receivables and expected future losses based primarily on its historical levels of bad debt losses. If the financial condition of a significant customer deteriorates resulting in its inability to pay its accounts when due, or if the Company’s overall loss history changes significantly, an adjustment in the Company’s allowance for doubtful accounts would be required, which could materially affect operating results.

Warranty

Warranty

The Company records an accrual for estimated warranty costs when revenue is recognized. The Company generally warrants its products for a period of one to five years. The warranty provision considers estimated product failure rates and trends, estimated replacement costs, estimated repair costs which include scrap costs, and estimated costs for customer compensatory claims related to product quality issues, if any. A statistical warranty tracking model is used to help prepare estimates and assist the Company in exercising judgment in determining the underlying estimates. The statistical tracking model captures specific detail on hard drive reliability, such as factory test data, historical field return rates, and costs to repair by product type. Management’s judgment is subject to a greater degree of subjectivity with respect to newly introduced products because of limited field experience with those products upon which to base warranty estimates. Management reviews the warranty accrual quarterly for products shipped in prior periods and which are still under warranty. Any changes in the estimates underlying the accrual may result in adjustments that impact current period gross profit and income. Such changes are generally a result of differences between forecasted and actual return rate experience and costs to repair. If actual product return trends, costs to repair returned products or costs of customer compensatory claims differ significantly from estimates, future results of operations could be materially affected.

Litigation and Other Contingencies

Litigation and Other Contingencies

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

Advertising Expense

Advertising Expense

Advertising costs are expensed as incurred. Selling, general and administrative expenses of the Company included advertising costs of $60 million, $61 million and $30 million in 2014, 2013 and 2012, respectively.

Income Taxes

Income Taxes

The Company accounts for income taxes under the asset and liability method, which provides that deferred tax assets and liabilities be recognized for temporary differences between the financial reporting basis and the tax basis of assets and liabilities and expected benefits of utilizing net operating loss (“NOL”) and tax credit carryforwards. The Company records a valuation allowance when it is more likely than not that the deferred tax assets will not be realized. Each period, the Company evaluates the need for a valuation allowance for its deferred tax assets and adjusts the valuation allowance so that the Company records net deferred tax assets only to the extent that it has concluded it is more likely than not that these deferred tax assets will be realized.

The Company recognizes liabilities for uncertain tax positions based on a two-step process. To the extent a tax position does not meet a more-likely-than-not level of certainty, no benefit is recognized in the financial statements. If a position meets the more-likely-than-not level of certainty, it is recognized in the financial statements at the largest amount that has a greater than 50% likelihood of being realized upon ultimate settlement. Interest and penalties related to unrecognized tax benefits are recognized on liabilities recorded for uncertain tax positions and are recorded in the provision for income taxes. The actual liability for unrealized tax benefits 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, and may materially affect the Company’s operating results.

Income Per Common Share

Income per Common Share

The Company computes basic income per common share using net income and the weighted average number of common shares outstanding during the period. Diluted income per common share is computed using net income and the weighted average number of common shares and potentially dilutive common shares outstanding during the period. Potentially dilutive common shares include certain dilutive outstanding employee stock options, rights to purchase shares of common stock under the Company’s Employee Stock Purchase Plan (“ESPP”) and restricted stock unit awards (“RSUs”).

The following table illustrates the computation of basic and diluted income per common share (in millions, except per share data):

	Years Ended
	June 27, 2014		June 28, 2013		June 29, 2012
Net income	$	1,617	$	980	$	1,612

Diluted	$	6.68	$	3.98	$	6.58
Anti-dilutive potential common shares excluded*	2		3		5

_______________

* For purposes of computing diluted income per common share, certain potentially dilutive securities have been excluded from the calculation because their effect would have been anti-dilutive.

Stock-based Compensation

Stock-based Compensation

The Company accounts for all stock-based compensation at fair value. Stock-based compensation cost is measured at the grant date based on the value of the award and is recognized as expense over the vesting period. The fair values of all stock options and cash-settled stock appreciation rights (“SARs”) granted are estimated using a binomial option-pricing model, and the fair values of all ESPP purchase rights are estimated using the Black-Scholes-Merton option-pricing model. The Company accounts for SARs as liability awards based upon management’s intention to settle such awards in cash. The SARs liability is recognized for that portion of fair value for the service period rendered at the reporting date. The share-based liability is remeasured at each reporting date through the requisite service period. Both the binomial and the Black-Scholes-Merton option-pricing models require the input of highly subjective assumptions. The Company is required to use judgment in estimating the amount of stock-based awards that are expected to be forfeited. If actual forfeitures differ significantly from the original estimate, stock-based compensation expense and the results of operations could be materially affected.

Other Comprehensive Income (Loss)

Other Comprehensive Income (Loss)

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, unrealized gains and losses on the Company's available-for-sale securities, foreign currency translation gains and losses and actuarial gains and losses related to pensions. The income tax impact on components of other comprehensive income is immaterial for all periods presented.

The following table illustrates the changes in the balances of each component of accumulated comprehensive income for 2014, 2013 and 2012:

	Actuarial Pension Gains (Losses)			Foreign Currency Translation Gains (Losses)			Unrealized Gains (Losses) on Foreign Exchange Contracts			Accumulated Other Comprehensive Income (Loss)

Foreign Exchange Contracts

Foreign Exchange Contracts

Although the majority of the Company’s transactions are in U.S. dollars, some transactions are based in various foreign currencies. The Company purchases short-term, foreign exchange contracts to hedge the impact of foreign currency fluctuations on certain underlying assets, liabilities and commitments for operating expenses and product costs denominated in foreign currencies. The purpose of entering into these hedging transactions is to minimize the impact of foreign currency fluctuations on the Company’s results of operations. These contract maturity dates do not exceed 12 months. All foreign exchange contracts are for risk management purposes only. The Company does not purchase foreign exchange contracts for trading purposes. The Company had foreign exchange contracts with commercial banks for British Pound Sterling, Euro, Japanese Yen, Malaysian Ringgit, Philippine Peso, Singapore Dollar and Thai Baht, which were designated as either cash flow or fair value hedges and had an aggregate notional amount of $1.5 billion and $2.0 billion at June 27, 2014 and June 28, 2013, respectively.

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 and presented within cash flow from operations. These amounts are subsequently recognized into earnings when the underlying cash flow being hedged is recognized into earnings. Recognized gains and losses on foreign exchange contracts entered into for manufacturing-related activities are reported in cost of revenue and presented within cash flow from operations. Hedge effectiveness is measured by comparing the hedging instrument’s cumulative change in fair value from inception to maturity to the underlying exposure’s terminal value. The Company determined the ineffectiveness associated with its cash flow hedges to be immaterial for all years presented.

A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of operating expenses. All fair value hedges were determined to be effective. The fair value and the changes in fair value on these contracts were immaterial to the consolidated financial statements for all years presented. See Notes 10 and 12 for additional disclosures related to foreign exchange contracts.

Pensions and Other Postretirement Benefit Plans

A change in the fair value of fair value hedges is recognized in earnings in the period incurred and is reported as a component of operating expenses. All fair value hedges were determined to be effective. The fair value and the changes in fair value on these contracts were immaterial to the consolidated financial statements for all years presented. See Notes 10 and 12 for additional disclosures related to foreign exchange contracts.

Pensions and Other Postretirement Benefit Plans

The Company has defined benefit pension plans and other postretirement plans covering certain employees in various countries. The benefits are based on the employees’ years of service and compensation. The plans are funded in conformity with the funding requirements of applicable government authorities. The Company amortizes unrecognized actuarial gains and losses and prior service costs on a straight-line basis over the remaining estimated average service life of the participants. The measurement date for the plans is the Company’s fiscal year-end. The Company recognizes the funded status of its defined benefit pension and postretirement plans in the consolidated balance sheets, with changes in the funded status recognized through accumulated other comprehensive income (loss) in the year in which such changes occur. See Note 14 for additional disclosures related to the Company’s pension and other postretirement benefit plans.

Use of Estimates

Use of Estimates

Company management has made estimates and assumptions relating to the reporting of certain assets and liabilities in conformity with U.S. GAAP. These estimates and assumptions have been applied using methodologies that are consistent throughout the periods presented. However, actual results could differ materially from these estimates.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In February 2013, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” (“ASU 2013-02”). The new standard requires an entity to provide information about the amounts reclassified out of accumulated other comprehensive income by component. The Company adopted this pronouncement in the first quarter of fiscal 2014. Since ASU 2013-02 related only to the presentation and disclosure of information, it did not have a material effect on the Company’s consolidated financial statements.

In July 2013, the FASB issued ASU 2013-11, "Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists" ("ASU 2013-11"). The new standard requires the presentation of certain unrecognized tax benefits as reductions to deferred tax assets rather than as liabilities in the consolidated balance sheets when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The new standard is effective for fiscal years and interim periods within those fiscal years, beginning after December 15, 2013, which for the Company is the first quarter of fiscal 2015. The Company does not expect the adoption of ASU 2013-11 to have a material impact on its consolidated financial statements.

In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers" ("ASU 2014-09"), which amends the guidance in former Accounting Standards Codification ("ASC") Topic 605, "Revenue Recognition", to provide a single, comprehensive revenue recognition model for all contracts with customers. The new standard requires an entity to recognize revenue in a manner that depicts the transfer of promised goods or services to customers in amounts that reflect the consideration to which an entity expects to be entitled in exchange for those goods or services. The new standard also requires entities to enhance disclosures about the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The new standard allows for either a full retrospective or a modified retrospective transition method and is effective for fiscal years beginning after December 15, 2016, which for the Company is the first quarter of fiscal 2018. The Company has not yet selected a transition method and is currently evaluating the impact ASU 2014-09 will have on its consolidated financial statements and related disclosures.

In April 2014, the FASB issued ASU 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity" ("ASU 2014-08"), which amends the criteria for determining which disposals can be presented as discontinued operations and enhances related disclosure requirements. Under the new guidance, a disposal of a component of an entity or a group of components of an entity is required to be reported in discontinued operations if the disposal represents a strategic shift that has or may have a major effect on an entity’s operations and financial results. The new standard is effective for fiscal years beginning after December 15, 2014, which for the Company is the first quarter of fiscal 2016. The Company does not expect the adoption of ASU 2014-08 to have a material impact on its consolidated financial statements.
